For bootstrap its works
<span class="form-control">$ <input type="text"/></span>
Don't use class="form-control" in input field.
remove this in your manifest file
xmlns:tools="http://schemas.android.com/tools"
You can use a window MAX() like this:
SELECT
*,
max_date = MAX(date) OVER (PARTITION BY group)
FROM table
to get max dates per group
alongside other data:
group date cash checks max_date
----- -------- ---- ------ --------
1 1/1/2013 0 0 1/3/2013
2 1/1/2013 0 800 1/1/2013
1 1/3/2013 0 700 1/3/2013
3 1/1/2013 0 600 1/5/2013
1 1/2/2013 0 400 1/3/2013
3 1/5/2013 0 200 1/5/2013
Using the above output as a derived table, you can then get only rows where date
matches max_date
:
SELECT
group,
date,
checks
FROM (
SELECT
*,
max_date = MAX(date) OVER (PARTITION BY group)
FROM table
) AS s
WHERE date = max_date
;
to get the desired result.
Basically, this is similar to @Twelfth's suggestion but avoids a join and may thus be more efficient.
You can try the method at SQL Fiddle.
If all you want is calling ravel
on your (nested, I s'pose?) list, you can do that directly, numpy
will do the casting for you:
L = [[1,None,3],["The", "quick", object]]
np.ravel(L)
# array([1, None, 3, 'The', 'quick', <class 'object'>], dtype=object)
Also worth mentioning that you needn't go through numpy
at all.
How about using name attribute for old browsers and id attribute to the new browsers. Both options will be used and fallback method will be implemented by default!!!
I'd re-iterate Donny V. answer and Josh's
"The only reason I wouldn't use the async version is if I were trying to support an older version of .NET that does not already have built in async support."
(and upvote if I had the reputation.)
I can't remember the last time if ever, I was grateful of the fact HttpWebRequest threw exceptions for status codes >= 400. To get around these issues you need to catch the exceptions immediately, and map them to some non-exception response mechanisms in your code...boring, tedious and error prone in itself. Whether it be communicating with a database, or implementing a bespoke web proxy, its 'nearly' always desirable that the Http driver just tell your application code what was returned, and leave it up to you to decide how to behave.
Hence HttpClient is preferable.
In Python:
# as Peter van der Wal's answer
re.split(r'\r\n|\r|\n', text, flags=re.M)

str.splitlines()
alert("I will get back to you soon\nThanks and Regards\nSaurav Kumar");

No, you cannot run windows containers directly on Linux.
But you can run Linux on Windows.
Windows Server/10 comes packaged with base image of ubuntu OS (after september 2016 beta service pack). That is the reason you can run linux on windows and not other wise. Check out here. https://thenewstack.io/finally-linux-containers-really-will-run-windows-linuxkit/
You can change between OS containers Linux and windows by right clicking on the docker in tray menu.
I ran into the same issue. What I needed to do was add a reference at the top of the class and change the CultureInfo of the thread that is currently executing.
using System.Threading;
string cultureName = "fr-CA";
Thread.CurrentThread.CurrentCulture = new CultureInfo(cultureName);
DateTime theDate = new DateTime(2015, 11, 06);
theDate.ToString("g");
Console.WriteLine(theDate);
All you have to do is change the culture name, for example: "en-US" = United States "fr-FR" = French-speaking France "fr-CA" = French-speaking Canada etc...
It's for validation purposes.
Validation It is common to validate a model after binding user input to it. Spring 3 provides support for declarative validation with JSR-303. This support is enabled automatically if a JSR-303 provider, such as Hibernate Validator, is present on your classpath. When enabled, you can trigger validation simply by annotating a Controller method parameter with the @Valid annotation: After binding incoming POST parameters, the AppointmentForm will be validated; in this case, to verify the date field value is not null and occurs in the future.
Look here for more info:
http://blog.springsource.com/2009/11/17/spring-3-type-conversion-and-validation/
I also faced the same problem.I resolved by doing the build by following steps as.
-->Right click on the project select RunAs ->Run configurations
Select your project as BaseDirectory. In place of goals give eclipse:eclipse install
-->In the second tab give -Xmx1024m as VM arguments.
You cloned your repo with SSH clone.
git config --get remote.origin.url
[email protected]:company/product/production.git
But you want to get http url to open it in the browser or share it:
git config --get remote.origin.url | sed -e 's/:/\//g'| sed -e 's/ssh\/\/\///g'| sed -e 's/git@/https:\/\//g'
https://gitlab.com/company/product/production.git
GitHub or GitLab doesn’t matter.
Just add to the CommandArgument
parameter and read it out on the Click
handler:
<asp:LinkButton ID="ENameLinkBtn" runat="server"
style="font-weight: 700; font-size: 8pt;" CommandArgument="YourValueHere"
OnClick="ENameLinkBtn_Click" >
Then in your click event:
protected void ENameLinkBtn_Click(object sender, EventArgs e)
{
LinkButton btn = (LinkButton)(sender);
string yourValue = btn.CommandArgument;
// do what you need here
}
Also you can set the CommandArgument
argument when binding if you are using the LinkButton
in any bindable controls by doing:
CommandArgument='<%# Eval("SomeFieldYouNeedArguementFrom") %>'
Unlike jQuery
in order to read raw JSON
you will need to decode it in PHP.
print_r(json_decode(file_get_contents("php://input"), true));
php://input
is a read-only stream that allows you to read raw data from the request body.
$_POST
is form variables, you will need to switch to form
radiobutton in postman
then use:
foo=bar&foo2=bar2
To post raw json
with jquery
:
$.ajax({
"url": "/rest/index.php",
'data': JSON.stringify({foo:'bar'}),
'type': 'POST',
'contentType': 'application/json'
});
if you want to start application with cmd use this code:
string YourApplicationPath = "C:\\Program Files\\App\\MyApp.exe"
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.WindowStyle = ProcessWindowStyle.Hidden;
processInfo.FileName = "cmd.exe";
processInfo.WorkingDirectory = Path.GetDirectoryName(YourApplicationPath);
processInfo.Arguments = "/c START " + Path.GetFileName(YourApplicationPath);
Process.Start(processInfo);
In .NET 4.5, at least, there's this version that is much shorter and has the added bonus of evaluating any file criteria for inclusion in the list:
public static IEnumerable<string> GetAllFiles(string path,
Func<FileInfo, bool> checkFile = null)
{
string mask = Path.GetFileName(path);
if (string.IsNullOrEmpty(mask)) mask = "*.*";
path = Path.GetDirectoryName(path);
string[] files = Directory.GetFiles(path, mask, SearchOption.AllDirectories);
foreach (string file in files)
{
if (checkFile == null || checkFile(new FileInfo(file)))
yield return file;
}
}
Use like this:
var list = GetAllFiles(mask, (info) => Path.GetExtension(info.Name) == ".html").ToList();
The while increments the i. So you get:
data[1][0]
data[2][0]
data[3][0]
...
It looks like name doesn't match any of the the elements of data. So, the while still increments and you reach the end of the array. I'll suggest to use for loop.
@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs
sizes so you won't notice, but if you used anything else (e.g. col-sm
, col-md
, etc), you'd understand.
Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/
.left-side {
background-color: blue;
padding-bottom: 1000px;
margin-bottom: -1000px;
height: 100%;
}
.something {
height: 100%;
background-color: red;
padding-bottom: 1000px;
margin-bottom: -1000px;
height: 100%;
}
.row {
background-color: green;
overflow: hidden;
}
Should we include a little JS? Because CSS was not basically created for this job. CSS was just a style sheet to add styles to the HTML, but its pseudo classes can do something that the basic CSS can't do. For example button:active
active is pseudo.
Reference:
http://css-tricks.com/pseudo-class-selectors/ You can learn more about pseudo here!
Your code:
The code that you're having the basic but helpfull. And yes :active
will only occur once the click event is triggered.
button {
font-size: 18px;
border: 2px solid gray;
border-radius: 100px;
width: 100px;
height: 100px;
}
button:active {
font-size: 18px;
border: 2px solid red;
border-radius: 100px;
width: 100px;
height: 100px;
}
This is what CSS would do, what rlemon suggested is good, but that would as he suggested would require a
tag.
How to use CSS:
You can use :focus
too. :focus
would work once the click is made and would stay untill you click somewhere else, this was the CSS, you were trying to use CSS, so use :focus
to make the buttons change.
What JS would do:
The JavaScript's jQuery library is going to help us for this code. Here is the example:
$('button').click(function () {
$(this).css('border', '1px solid red');
}
This will make sure that the button stays red even if the click gets out. To change the focus type (to change the color of red to other) you can use this:
$('button').click(function () {
$(this).css('border', '1px solid red');
// find any other button with a specific id, and change it back to white like
$('button#red').css('border', '1px solid white');
}
This way, you will create a navigation menu. Which will automatically change the color of the tabs as you click on them. :)
Hope you get the answer. Good luck! Cheers.
I wrote a small CLI in Python and added GFM support. It's called Grip (Github Readme Instant Preview).
Install it with:
$ pip install grip
And to use it, simply:
$ grip
Then visit localhost:5000
to view the readme.md
file at that location.
You can also specify your own file:
$ grip CHANGES.md
And change port:
$ grip 8080
And of course, specifically render GitHub-Flavored Markdown, optionally with repository context:
$ grip --gfm --context=username/repo issue.md
Notable features:
stdin
and export to stdout
added in 3.0Hope this helps someone here. Check it out.
It seems to me like using a REGEX in this case would just be overkill. Why not just just strpos to find the space character. Also, there's nothing special about the space character in regular expressions, you should be able to search for it the same as you would search for any other character. That is, unless you disabled pattern whitespace, which would hardly be necessary in this case.
The simple way is to connect the delegate of UITextField
to self (self.mytestField.delegate = self
) and dismiss the keyboard in the method textFieldShouldReturn
using [textField resignFirstResponder];
Another way to dismiss the keyboard is the following:
Objective-C
[self.view endEditing:YES];
Swift:
self.view.endEditing(true)
Put [self.view endEditing:YES];
where you would like to dismiss the keyboard (Button event, Touch event, etc.).
You can check this
[Route("Report/MyReport")]
public IHttpActionResult GetReport()
{
string url = "https://localhost:44305/Templates/ReportPage.html";
System.Uri uri = new System.Uri(url);
return Redirect(uri);
}
Since none of the answers mentioned the upcoming Ranges library, which is available in the standard library since C++20, and currently separately available on GitHub as range-v3
, I would like to add a way to perform this conversion using it.
To modify the string in-place:
str |= action::transform([](unsigned char c){ return std::tolower(c); });
To generate a new string:
auto new_string = original_string
| view::transform([](unsigned char c){ return std::tolower(c); });
(Don't forget to #include <cctype>
and the required Ranges headers.)
Note: the use of unsigned char
as the argument to the lambda is inspired by cppreference, which states:
Like all other functions from
<cctype>
, the behavior ofstd::tolower
is undefined if the argument's value is neither representable asunsigned char
nor equal toEOF
. To use these functions safely with plainchar
s (orsigned char
s), the argument should first be converted tounsigned char
:char my_tolower(char ch) { return static_cast<char>(std::tolower(static_cast<unsigned char>(ch))); }
Similarly, they should not be directly used with standard algorithms when the iterator's value type is
char
orsigned char
. Instead, convert the value tounsigned char
first:std::string str_tolower(std::string s) { std::transform(s.begin(), s.end(), s.begin(), // static_cast<int(*)(int)>(std::tolower) // wrong // [](int c){ return std::tolower(c); } // wrong // [](char c){ return std::tolower(c); } // wrong [](unsigned char c){ return std::tolower(c); } // correct ); return s; }
You can use karma-jasmine plugin to set the default time out interval globally.
Add this config in karma.conf.js
module.exports = function(config) {
config.set({
client: {
jasmine: {
timeoutInterval: 10000
}
}
})
}
Use:
if (function_exists('curl_file_create')) { // php 5.5+
$cFile = curl_file_create($file_name_with_full_path);
} else { //
$cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);
You can also refer:
http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/
Important hint for PHP 5.5+:
Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
From the screenshot I can see that you want to pass "user" and "password" values to the service. You have send the parameter values in the request header part which is wrong.
The values are sent in the request body and not in the request header.
Also your syntax is wrong.
Correct syntax is: {"user":"user_val","password":"password_val"}.
Also check what is the the content type. It should match with the content type you have set to your service.
If you are using git for Windows.

In case this is of use to some newer dev's because its not specified above. Just to be very explicit:
You need two things if using onConfigurationChanged:
An onConfigurationChanged
method in your Activity Class
Specify in your manifest which configuration changes will be handled by your onConfigurationChanged
method
The manifest snippet in the above answers, while no doubt correct for the particular app that manifest belongs to, is NOT exactly what you need to add in your manifest to trigger the onConfigurationChanged method in your Activity Class. i.e. the below manifest entry may not be correct for your app.
<activity name= ".MainActivity" android:configChanges="orientation|screenSize"/>
In the above manifest entry, there are various Android actions for android:configChanges=""
which can trigger the onCreate in your Activity lifecycle.
This is very important - The ones NOT Specified in the manifest are the ones that trigger your onCreate and The ones specified in the manifest are the ones that trigger your onConfigurationChanged
method in your Activity Class.
So you need to identify which config changes you need to handle yourself. For the Android Encyclopedically Challenged like me, I used the quick hints pop-out in Android Studio and added in almost every possible configuration option. Listing all of these basically said that I would handle everything and onCreate will never be called due to configurations.
<activity name= ".MainActivity" android:configChanges="screenLayout|touchscreen|mnc|mcc|density|uiMode|fontScale|orientation|keyboard|layoutDirection|locale|navigation|smallestScreenSize|keyboardHidden|colorMode|screenSize"/>
Now obviously I don't want to handle everything, so I began eliminating the above options one at a time. Re-building and testing my app after each removal.
Another important point: If there is just one configuration option being handled automatically that triggers your onCreate (You do not have it listed in your manifest above), then it will appear like onConfigurationChanged
is not working. You must put all relevant ones into your manifest.
I ended up with 3 that were triggering onCreate originally, then I tested on an S10+ and I was still getting the onCreate, so I had to do my elimination exercise again and I also needed the |screenSize
. So test on a selection of platforms.
<activity name= ".MainActivity" android:configChanges="screenLayout|uiMode|orientation|screenSize"/>
So my suggestion, although I'm sure someone can poke holes in this:
Add your onConfigurationChanged
method in your Activity Class with a TOAST or LOG so you can see when its working.
Add all possible configuration options to your manifest.
Confirm your onConfigurationChanged
method is working by testing your app.
Remove each config option from your manifest file one at a time, testing your app after each.
Test on as large a variety of devices as possible.
Do not copy/paste my snippet above to your manifest file. Android updates change the list, so use the pop-out Android Studio hints to make sure you get them all.
I hope this saves someone some time.
My onConfigurationChanged
method just for info below. onConfigurationChanged
is called in the lifecycle after the new orientation is available, but before the UI has been recreated. Hence my first if
to check the orientation works correctly, and then the 2nd nested if
to look at the visibility of my UI ImageView also works correctly.
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
pokerCardLarge = findViewById(R.id.pokerCardLgImageView);
if(pokerCardLarge.getVisibility() == pokerCardLarge.VISIBLE){
Bitmap image = ((BitmapDrawable)pokerCardLarge.getDrawable()).getBitmap();
pokerCardLarge.setVisibility(pokerCardLarge.VISIBLE);
pokerCardLarge.setImageBitmap(image);
}
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
pokerCardLarge = findViewById(R.id.pokerCardLgImageView);
if(pokerCardLarge.getVisibility() == pokerCardLarge.VISIBLE){
Bitmap image = ((BitmapDrawable)pokerCardLarge.getDrawable()).getBitmap();
pokerCardLarge.setVisibility(pokerCardLarge.VISIBLE);
pokerCardLarge.setImageBitmap(image);
}
}
}
I think this simply demonstrates what you are trying to achieve:
# coding: utf-8
class Class():
count = 0
names = []
def __init__(self,name):
self.number = Class.count
self.name = name
Class.count += 1
Class.names.append(name)
l=[]
l.append(Class("uno"))
l.append(Class("duo"))
print l
print l[0].number, l[0].name
print l[1].number, l[1].name
print Class.count, Class.names
Run the code above and you get:-
[<__main__.Class instance at 0x6311b2c>,
<__main__.Class instance at 0x63117ec>]
0 uno
1 duo
2 ['uno', 'duo']

sudo docker cp path/on/your/machine adam_ubuntu:/root/path_in_container

Steps for executing the 'Lex' program:
I faced the same problem and I was able to fix it using @slomek's answer but the issue resurfaced after that.
I finally fixed it by adding my project's output folder to the JUnit test's run configuration. Steps are:
Project properties -> Java Build Path -> Default output folder
<project-folder>/bin
Run -> Run Configurations...
Classpath
tabUser Entries
- even if the project is already included there
Advanced -> Add folder
to add the output folderThis issue might be due to weird project setup in Eclipse - e.g. source folder with nested maven projects imported as a single project/folder (at least that was how my project was setup).
I also spent several hours fighting with this as well. The fix is real simple. Edit your Entitlements.plist file in the root of your project's directory. Find the line that says <key>get-task-allow</key>
. Underneath it should be <false/>
. Change that to <true/>
.
Try out this will solve ur problem ....
EditText etxt = (EditText)findviewbyid(R.id.etxt);
String str_value = etxt.getText().toString();
Ruby 2.6.0 enables casting to an integer without raising an exception, and will return nil
if the cast fails. And since nil
mostly behaves like false
in Ruby, you can easily check for an integer like so:
if Integer(my_var, exception: false)
# do something if my_var can be cast to an integer
end
You can do:
>>> a = 'ZENOVW'
>>> ''.join(sorted(a))
'ENOVWZ'
With Jenkins CLI you do not have to reload everything - you just can load the job (update-job command). You can't use tokens with CLI, AFAIK - you have to use password or password file.
Token name for user can be obtained via http://<jenkins-server>/user/<username>/configure
- push on 'Show API token' button.
Here's a link on how to use API tokens (it uses wget
, but curl
is very similar).
Avoid using
RETURN
statement when you are using
BEGIN TRY
...
END TRY
BEGIN CATCH
...
END CATCH
and
BEGIN, COMMIT & ROLLBACK
statements in SQL stored procedures
All DDL statements in Oracle PL/SQL should use Execute Immediate before the statement. Hence you should use:
execute immediate 'truncate table schema.tablename';

To expound on Stephane's answer.
I got this error when I tried to grant remote connections privileges of a particular database to a root
user on MySQL server by running the command:
USE database_name;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
This gave an error:
ERROR 1133 (42000): Can't find any matching row in the user table
Here's how I fixed it:
First, confirm that your MySQL server allows for remote connections. Use your preferred text editor to open the MySQL server configuration file:
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Scroll down to the bind-address line and ensure that is either commented out or replaced with 0.0.0.0
(to allow all remote connections) or replaced with Ip-Addresses that you want remote connections from.
Once you make the necessary changes, save and exit the configuration file. Apply the changes made to the MySQL config file by restarting the MySQL service:
sudo systemctl restart mysql
Next, log into the MySQL server console on the server it was installed:
mysql -u root -p
Enter your mysql user password
Check the hosts that the user you want has access to already. In my case the user is root
:
SELECT host FROM mysql.user WHERE user = "root";
This gave me this output:
+-----------+
| host |
+-----------+
| localhost |
+-----------+
Next, I ran the command below which is similar to the previous one that was throwing errors, but notice that I added a password to it this time:
USE database_name;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'my-password';
Note: %
grants a user remote access from all hosts on a network. You can specify the Ip-Address of the individual hosts that you want to grant the user access from using the command - GRANT ALL PRIVILEGES ON *.* TO 'root'@'Ip-Address' IDENTIFIED BY 'my-password';
Afterwhich I checked the hosts that the user now has access to. In my case the user is root
:
SELECT host FROM mysql.user WHERE user = "root";
This gave me this output:
+-----------+
| host |
+-----------+
| % |
| localhost |
+-----------+
Finally, you can try connecting to the MySQL server from another server using the command:
mysql -u username -h mysql-server-ip-address -p
Where u represents user, h represents mysql-server-ip-address and p represents password. So in my case it was:
mysql -u root -h 34.69.261.158 -p
Enter your mysql user password
You should get this output depending on your MySQL server version:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 4

That's all.
I hope this helps
The following approach will work only if the chars are 1 byte. (Default unicode will not work since it is 2 bytes)
public static byte[] ToByteArray(string value)
{
char[] charArr = value.ToCharArray();
byte[] bytes = new byte[charArr.Length];
for (int i = 0; i < charArr.Length; i++)
{
byte current = Convert.ToByte(charArr[i]);
bytes[i] = current;
}
return bytes;
}
Keeping it simple
I was getting the exact same error for forgetting to remove the .class extension when running the JAVA class. So instead of this:
java myClass.class
One should do this:
java myClass
You need to change public void klik(PaintEventArgs pea, EventArgs e)
to public void klik(object sender, System.EventArgs e)
because there is no Click
event handler with parameters PaintEventArgs pea, EventArgs e
.
I don't know if this was true at the time of the original posting, but the siblings method allows selectors, so a reduction of what the OP listed should work.
$(this).siblings(':not(.closedTab)');
You can simply use:
List<string> items = new List<string>() { "foo", "boo", "john", "doe" };
Console.WriteLine(string.Join(",", items));
Happy coding!
Renaming a worksheet manually in Excel, you hit a limit of 31 chars, so I'd suggest that that's a hard limit.
I had a similar issue and it turned out that i had to add an extra entry in cmake
to include the files.
Since i was also using the zmq library I had to add this to the included libraries as well.
Nothing helps me but this:

You are calling get with the wrong argument.
It should be:

The existing answers which leverage SJCL, CryptoJS, and/or WebCrypto aren't necessarily wrong but they're not as safe as you might initially suspect. Generally you want to use libsodium. First I'll explain why, then how.
Short answer: In order for your encryption to actually be secure, these libraries expect you to make too many choices e.g. the block cipher mode (CBC, CTR, GCM; if you can't tell which of the three I just listed is secure to use and under what constraints, you shouldn't be burdened with this sort of choice at all).
Unless your job title is cryptography engineer, the odds are stacked against you implementing it securely.
CryptoJS offers a handful of building blocks and expects you to know how to use them securely. It even defaults to CBC mode (archived).
Read this write-up on AES-CBC vulnerabilities.
WebCrypto is a potluck standard, designed by committee, for purposes that are orthogonal to cryptography engineering. Specifically, WebCrypto was meant to replace Flash, not provide security.
SJCL's public API and documentation begs users to encrypt data with a human-remembered password. This is rarely, if ever, what you want to do in the real world.
Additionally: Its default PBKDF2 round count is roughly 86 times as small as you want it to be. AES-128-CCM is probably fine.
Out of the three options above, SJCL is the least likely to end in tears. But there are better options available.
You don't need to choose between a menu of cipher modes, hash functions, and other needless options. You'll never risk screwing up your parameters and removing all security from your protocol.
Instead, libsodium just gives you simple options tuned for maximum security and minimalistic APIs.
crypto_box()
/ crypto_box_open()
offer authenticated public-key encryption.
crypto_secretbox()
/ crypto_secretbox_open()
offer shared-key authenticated encryption.
Additionally, libsodium has bindings in dozens of popular programming languages, so it's very likely that libsodium will just work when trying to interoperate with another programming stack. Also, libsodium tends to be very fast without sacrificing security.
First, you need to decide one thing:
If you selected the first option, get CipherSweet.js.
The documentation is available online. EncryptedField
is sufficient for most use cases, but the EncryptedRow
and EncryptedMultiRows
APIs may be easier if you have a lot of distinct fields you want to encrypt.
With CipherSweet, you don't need to even know what a nonce/IV is to use it securely.
Additionally, this handles int
/float
encryption without leaking facts about the contents through ciphertext size.
Otherwise, you'll want sodium-plus, which is a user-friendly frontend to various libsodium wrappers. Sodium-Plus allows you to write performant, asynchronous, cross-platform code that's easy to audit and reason about.
To install sodium-plus, simply run...
npm install sodium-plus
There is currently no public CDN for browser support. This will change soon. However, you can grab sodium-plus.min.js
from the latest Github release if you need it.
const { SodiumPlus } = require('sodium-plus');_x000D_
let sodium;_x000D_
_x000D_
(async function () {_x000D_

_x000D_
console.log(decrypted.toString());_x000D_

The documentation for sodium-plus is available on Github.
If you'd like a step-by-step tutorial, this dev.to article has what you're looking for.
Use svn cat
or svn export
.
For that, you don't need to fetch the working directory, but you will not be able to commit any changes you make. If you need to make changes and commit them, you need a working directory, but you don't have to fetch it completely. Checkout the revision where the directory was still/almost empty, and then use 'svn cat' to extract the file from HEAD.
Yes, this could be done with a regular expression. Keep in mind that Java's regular expressions have different syntax from SQL's "like". Instead of "%
", you would have ".*
", and instead of "?
", you would have ".
".
What makes it somewhat tricky is that you would also have to escape any characters that Java treats as special. Since you're trying to make this analogous to SQL, I'm guessing that ^$[]{}\
shouldn't appear in the regex string. But you will have to replace ".
" with "\\.
" before doing any other replacements. (Edit: Pattern.quote(String)
escapes everything by surrounding the string with "\Q
" and "\E
", which will cause everything in the expression to be treated as a literal (no wildcards at all). So you definitely don't want to use it.)
Furthermore, as Dave Webb says, you also need to ignore case.
With that in mind, here's a sample of what it might look like:
public static boolean like(String str, String expr) {
expr = expr.toLowerCase(); // ignoring locale for now
expr = expr.replace(".", "\\."); // "\\" is escaped to "\" (thanks, Alan M)
// ... escape any other potentially problematic characters here
expr = expr.replace("?", ".");
expr = expr.replace("%", ".*");
str = str.toLowerCase();
return str.matches(expr);
}
You can suppress the space by printing an empty string to stdout between the print
statements.
>>> import sys
>>> for i in range(20):
... print 'a',
... sys.stdout.write('')
...
aaaaaaaaaaaaaaaaaaaa
However, a cleaner solution is to first build the entire string you'd like to print and then output it with a single print
statement.
I went to the docker settings and changed the image space available. It reached the limit while creating the new image with docker build
. So I just increased the amount available.
As others have pointed out, output can be buffered within your program before a console or shell has a chance to see it.
On unix-like systems, including macs, stdout
has line-based buffering by default. This means that your program empties its stdout
buffer as soon as it sees a newline.
However, on windows, newlines are no longer special, and full buffering is used. Windows doesn't support line buffering at all; see the msdn page on setvbuf.
So on windows, a good approach is to completely shut off stdout
buffering like so:
setvbuf (stdout, NULL, _IONBF, 0);
Here's a very minimal and secure implementation of a Claims based Authentication using JWT token in an ASP.NET Core Web API.
first of all, you need to expose an endpoint that returns a JWT token with claims assigned to a user:
/// <summary>
/// Login provides API to verify user and returns authentication token.
/// API Path: api/account/login
/// </summary>
/// <param name="paramUser">Username and Password</param>
/// <returns>{Token: [Token] }</returns>
[HttpPost("login")]
[AllowAnonymous]
public async Task<IActionResult> Login([FromBody] UserRequestVM paramUser, CancellationToken ct)
{
var result = await UserApplication.PasswordSignInAsync(paramUser.Email, paramUser.Password, false, lockoutOnFailure: false);
if (result.Succeeded)
{
UserRequestVM request = new UserRequestVM();
request.Email = paramUser.Email;
ApplicationUser UserDetails = await this.GetUserByEmail(request);
List<ApplicationClaim> UserClaims = await this.ClaimApplication.GetListByUser(UserDetails);
var Claims = new ClaimsIdentity(new Claim[]
{
new Claim(JwtRegisteredClaimNames.Sub, paramUser.Email.ToString()),
new Claim(UserId, UserDetails.UserId.ToString())
});
//Adding UserClaims to JWT claims
foreach (var item in UserClaims)
{
Claims.AddClaim(new Claim(item.ClaimCode, string.Empty));
}
var tokenHandler = new JwtSecurityTokenHandler();
// this information will be retrived from you Configuration
//I have injected Configuration provider service into my controller
var encryptionkey = Configuration["Jwt:Encryptionkey"];
var key = Encoding.ASCII.GetBytes(encryptionkey);
var tokenDescriptor = new SecurityTokenDescriptor
{
Issuer = Configuration["Jwt:Issuer"],
Subject = Claims,
// this information will be retrived from you Configuration
//I have injected Configuration provider service into my controller
Expires = DateTime.UtcNow.AddMinutes(Convert.ToDouble(Configuration["Jwt:ExpiryTimeInMinutes"])),
//algorithm to sign the token
SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)
};
var token = tokenHandler.CreateToken(tokenDescriptor);
var tokenString = tokenHandler.WriteToken(token);
return Ok(new
{
token = tokenString
});
}
return BadRequest("Wrong Username or password");
}
now you need to Add Authentication to your services in your ConfigureServices
inside your startup.cs to add JWT authentication as your default authentication service like this:
services.AddAuthentication(x =>
{
x.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
x.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(cfg =>
{
cfg.RequireHttpsMetadata = false;
cfg.SaveToken = true;
cfg.TokenValidationParameters = new TokenValidationParameters()
{
//ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(configuration["JWT:Encryptionkey"])),
ValidateAudience = false,
ValidateLifetime = true,
ValidIssuer = configuration["Jwt:Issuer"],
//ValidAudience = Configuration["Jwt:Audience"],
//IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["JWT:Key"])),
};
});
now you can add policies to your authorization services like this:
services.AddAuthorization(options =>
{
options.AddPolicy("YourPolicyNameHere",
policy => policy.RequireClaim("YourClaimNameHere"));
});
ALTERNATIVELY, You can also (not necessary) populate all of your claims from your database as this will only run once on your application startup and add them to policies like this:
services.AddAuthorization(async options =>
{
var ClaimList = await claimApplication.GetList(applicationClaim);
foreach (var item in ClaimList)
{
options.AddPolicy(item.ClaimCode, policy => policy.RequireClaim(item.ClaimCode));
}
});
now you can put the Policy filter on any of the methods that you want to be authorized like this:
[HttpPost("update")]
[Authorize(Policy = "ACC_UP")]
public async Task<IActionResult> Update([FromBody] UserRequestVM requestVm, CancellationToken ct)
{
//your logic goes here
}
Hope this helps
You can use stuff in place of replace for avoiding the bug that Hamlet Hakobyan has mentioned
CREATE FUNCTION dbo.StripWWWandCom (@input VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
DECLARE @Work VARCHAR(250)
SET @Work = @Input
--SET @Work = REPLACE(@Work, 'www.', '')
SET @Work = Stuff(@Work,1,4, '')
SET @Work = REPLACE(@Work, '.com', '')
RETURN @work
END
// This allows us to resize the image. It prevents skewed images and
// also vertically long images caused by trying to maintain the aspect
// ratio on images who's height is larger than their width
public void ResizeImage(string OriginalFile, string NewFile, int NewWidth, int MaxHeight, bool OnlyResizeIfWider)
{
System.Drawing.Image FullsizeImage = System.Drawing.Image.FromFile(OriginalFile);
// Prevent using images internal thumbnail
FullsizeImage.RotateFlip(System.Drawing.RotateFlipType.Rotate180FlipNone);
FullsizeImage.RotateFlip(System.Drawing.RotateFlipType.Rotate180FlipNone);
if (OnlyResizeIfWider)
{
if (FullsizeImage.Width <= NewWidth)
{
NewWidth = FullsizeImage.Width;
}
}
int NewHeight = FullsizeImage.Height * NewWidth / FullsizeImage.Width;
if (NewHeight > MaxHeight)
{
// Resize with height instead
NewWidth = FullsizeImage.Width * MaxHeight / FullsizeImage.Height;
NewHeight = MaxHeight;
}
System.Drawing.Image NewImage = FullsizeImage.GetThumbnailImage(NewWidth, NewHeight, null, IntPtr.Zero);
// Clear handle to original file so that we can overwrite it if necessary
FullsizeImage.Dispose();
// Save resized picture
NewImage.Save(NewFile);
}
Two solutions for this:
PHP function nl2br()
:
e.g.,
echo nl2br("This\r\nis\n\ra\nstring\r");
// will output
This<br />
is<br />
a<br />
string<br />
Wrap the input in <pre></pre>
tags.
I experienced this today. The value in Config was the updated one but the application would return the older value, stop and starting the solution did nothing.
So I cleared the .Net Temp folder.
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
It shouldn't create bugs but to be safe close your solution down first. Clear the Temporary ASP.NET Files then load up your solution.
My issue was sorted.
This happens when classes belonging to the same package are loaded from different JAR files, and those JAR files have signatures signed with different certificates - or, perhaps more often, at least one is signed and one or more others are not (which includes classes loaded from directories since those AFAIK cannot be signed).
So either make sure all JARs (or at least those which contain classes from the same packages) are signed using the same certificate, or remove the signatures from the manifest of JAR files with overlapping packages.
The code you posted gives the critical value for a one-sided test (Hence the answer to you question is simply:
abs(qt(0.25, 40)) # 75% confidence, 1 sided (same as qt(0.75, 40))
abs(qt(0.01, 40)) # 99% confidence, 1 sided (same as qt(0.99, 40))
Note that the t-distribution is symmetric. For a 2-sided test (say with 99% confidence) you can use the critical value
abs(qt(0.01/2, 40)) # 99% confidence, 2 sided
Another approach in spark 2.1.0
is to use --conf spark.driver.userClassPathFirst=true
during spark-submit which changes the priority of dependency load, and thus the behavior of the spark-job, by giving priority to the jars the user is adding to the class-path with the --jars
option.
I would choose an existing and already tested solution. For example this from rxjs in typescript:
function isNumeric(val: any): val is number | string {
// parseFloat NaNs numeric-cast false positives (null|true|false|"")
// ...but misinterprets leading-number strings, particularly hex literals ("0x...")
// subtraction forces infinities to NaN
// adding 1 corrects loss of precision from parseFloat (#15100)
return !isArray(val) && (val - parseFloat(val) + 1) >= 0;
}
Without rxjs isArray() function and with simplefied typings:
function isNumeric(val: any): boolean {
return !(val instanceof Array) && (val - parseFloat(val) + 1) >= 0;
}
You should always test such functions with your use cases. If you have special value types, this function may not be your solution. You can test the function here.
Results are:
enum : CardTypes.Debit : true
decimal : 10 : true
hexaDecimal : 0xf10b : true
binary : 0b110100 : true
octal : 0o410 : true
stringNumber : '10' : true
string : 'Hello' : false
undefined : undefined : false
null : null : false
function : () => {} : false
array : [80, 85, 75] : false
turple : ['Kunal', 2018] : false
object : {} : false
As you can see, you have to be careful, if you use this function with enums.
Try this:
Swift 2.0:
textField.userInteractionEnabled = false
Swift 3.0:
textField.isUserInteractionEnabled = false
Or in storyboard uncheck "User Interaction Enabled"
If you would like to query all columns
List<Users> list_users = new List<Users>();
MySqlConnection cn = new MySqlConnection("connection");
MySqlCommand cm = new MySqlCommand("select * from users",cn);
try
{
cn.Open();
MySqlDataReader dr = cm.ExecuteReader();
while (dr.Read())
{
list_users.Add(new Users(dr));
}
}
catch { /* error */ }
finally { cn.Close(); }
The User's constructor would do all the "dr.GetString(i)"
If you want to give your integer values, you can use a structure like below
public enum A
{
B(0),
C(10),
None(11);
int id;
private A(int i){id = i;}
public int GetID(){return id;}
public boolean IsEmpty(){return this.equals(A.None);}
public boolean Compare(int i){return id == i;}
public static A GetValue(int _id)
{
A[] As = A.values();
for(int i = 0; i < As.length; i++)
{
if(As[i].Compare(_id))
return As[i];
}
return A.None;
}
}
You can use a background image
.application-title img {_x000D_
width:200px;_x000D_
height:200px;_x000D_
box-sizing:border-box;_x000D_
padding-left: 200px;_x000D_
/*width of the image*/_x000D_
background: url(http://lorempixel.com/200/200/city/2) left top no-repeat;_x000D_
}
_x000D_
<div class="application-title">_x000D_
<img src="http://lorempixel.com/200/200/city/1/">_x000D_
</div><br />_x000D_
Original Image: <br />_x000D_
_x000D_
<img src="http://lorempixel.com/200/200/city/1/">
_x000D_
in visualstudio 2008 you could use this code :
var _assembly = System.Reflection.Assembly
.GetExecutingAssembly().GetName().CodeBase;
var _path = System.IO.Path.GetDirectoryName(_assembly) ;
You can try these snippets.
In [16]:mydata = {'x' : [10, 50, 18, 32, 47, 20], 'y' : ['12', '11', 'N/A', '13', '15', 'N/A']} In [17]:df=pd.DataFrame(mydata) In [18]:df.y[df.y=="N/A"]=np.nan Out[19]:df x y 0 10 12 1 50 11 2 18 NaN 3 32 13 4 47 15 5 20 NaN
Well, it's fairly simple to do.
On the window resize event handler, calculate how much the window has grown/shrunk, and use that fraction to adjust 1) Height, 2) Width, 3) Canvas.Top, 4) Canvas.Left properties of all the child controls inside the canvas.
Here's the code:
private void window1_SizeChanged(object sender, SizeChangedEventArgs e)
{
myCanvas.Width = e.NewSize.Width;
myCanvas.Height = e.NewSize.Height;
double xChange = 1, yChange = 1;
if (e.PreviousSize.Width != 0)
xChange = (e.NewSize.Width/e.PreviousSize.Width);
if (e.PreviousSize.Height != 0)
yChange = (e.NewSize.Height / e.PreviousSize.Height);
foreach (FrameworkElement fe in myCanvas.Children )
{
/*because I didn't want to resize the grid I'm having inside the canvas in this particular instance. (doing that from xaml) */
if (fe is Grid == false)
{
fe.Height = fe.ActualHeight * yChange;
fe.Width = fe.ActualWidth * xChange;
Canvas.SetTop(fe, Canvas.GetTop(fe) * yChange);
Canvas.SetLeft(fe, Canvas.GetLeft(fe) * xChange);
}
}
}
First of all, you do not have to develop any form yourself : phpMyAdmin, depending on its configuration (i.e. config.inc.php
) will display an identification form, asking for a login and password.
To get that form, you should not use :
$cfg['Servers'][$i]['auth_type'] = 'config';
But you should use :
$cfg['Servers'][$i]['auth_type'] = 'cookie';
(At least, that's what I have on a server which prompts for login/password, using a form)
For more informations, you can take a look at the documentation :
'config'
authentication ($auth_type = 'config'
) is the plain old way: username and password are stored in config.inc.php.'cookie'
authentication mode ($auth_type = 'cookie'
) as introduced in 2.2.3 allows you to log in as any valid MySQL user with the help of cookies.
Username and password are stored in cookies during the session and password is deleted when it ends.
You can use Jquery's on method and listen for the scroll
event.
All the above mentioned answers will almost fullfill the purpose. However, You need to drop the temp table after all the operation on it. You can follow-
INSERT INTO #TempTable (ID, Date, Name) SELECT id, date, name FROM physical_table;
IF OBJECT_ID('tempdb.dbo.#TempTable') IS NOT NULL DROP TABLE #TempTable;
I found that if the value passed is a string type, it must be followed by 'px' (i.e. 90px), where if the value is an integer, it will append the px automatically. the width and height properties are more forgiving (either type works).
var x = "90";
var y = "120"
$(selector).css( { left: x, top: y } ) //doesn't work
$(selector).css( { left: x + "px", top: y + "px" } ) //does work
x = 90;
y = 120;
$(selector).css( { left: x, top: y } ) //does work
I've used the following method to detect if a string contains only whitespace. It also matches empty strings.
if (/^\s*$/.test(myStr)) {
// the string contains only whitespace
}
More accurate for Edge (do not include latest IE 15) is:
@supports (display:-ms-grid) { ... }
@supports (-ms-ime-align:auto) { ... }
works for all Edge versions (currently up to IE15).
Just copy your favicon on: /yourappname/mainapp(ex:core)/static/mainapp(ex:core)/img
Then go to your mainapp template(ex:base.html) and just copy this, after {% load static %} because you must load first the statics.
<link href="{% static 'core/img/favi_x.png' %}" rel="shortcut icon" type="image/png" />
I was getting this error attempting to run "php artisan migrate" on Windows with a virtual box / vagrant / homestead installation.
The documentation said I had to run this command on the virtual machine.
This worked!!!
make sure to do it inside your current project folder.
You can use the V3 API to get a raw file like this (you'll need an OAuth token):
curl -H 'Authorization: token INSERTACCESSTOKENHERE' -H 'Accept: application/vnd.github.v3.raw' -O -L https://api.github.com/repos/*owner*/*repo*/contents/*path*
All of this has to go on one line. The -O
option saves the file in the current directory. You can use -o filename
to specify a different filename.
To get the OAuth token follow the instructions here: https://help.github.com/articles/creating-an-access-token-for-command-line-use
I've written this up as a gist as well: https://gist.github.com/madrobby/9476733
Lets try the shortest possible definition:
Lexical Scoping defines how variable names are resolved in nested functions: inner functions contain the scope of parent functions even if the parent function has returned.
That is all there is to it!
Here is the solution to copy files from Linux to Windows using SCP without password by ssh:
Install sshpass in Linux machine to skip password prompt
Script
sshpass -p 'xxxxxxx' scp /home/user1/*.* [email protected]:/d/test/
Details:
sshpass -p 'password' scp /source_path/*.* windowsusername@windowsMachine_ip:/destination_drive/subfolder/
You can use link-rewriting to append a unique identifier to all your URLs when starting at a single page (e.g. index.html/jsp/whatever). The browser will use the same cookies for all your tabs so everything you put in cookies will not be unique.
Inside the DataTemplate
you're working in the context of a Rule
, that's why you cannot bind to SelectedRule.Name
-- there is no such property on a Rule
.
To bind to the original data context (which is your ViewModel) you can write:
<TextBlock Text="{Binding ElementName=lbRules, Path=DataContext.SelectedRule.Name}" />
UPDATE: regarding the SelectedItem property binding, it looks perfectly valid, I tried the same on my machine and it works fine. Here is my full test app:
XAML:
<Window x:Class="TestWpfApplication.ListBoxSelectedItem"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="ListBoxSelectedItem" Height="300" Width="300"
xmlns:app="clr-namespace:TestWpfApplication">
<Window.DataContext>
<app:ListBoxSelectedItemViewModel/>
</Window.DataContext>
<ListBox ItemsSource="{Binding Path=Rules}" SelectedItem="{Binding Path=SelectedRule, Mode=TwoWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Name:" />
<TextBox Text="{Binding Name}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Window>
Code behind:
namespace TestWpfApplication
{
/// <summary>
/// Interaction logic for ListBoxSelectedItem.xaml
/// </summary>
public partial class ListBoxSelectedItem : Window
{
public ListBoxSelectedItem()
{
InitializeComponent();
}
}
public class Rule
{
public string Name { get; set; }
}
public class ListBoxSelectedItemViewModel
{
public ListBoxSelectedItemViewModel()
{
Rules = new ObservableCollection<Rule>()
{
new Rule() { Name = "Rule 1"},
new Rule() { Name = "Rule 2"},
new Rule() { Name = "Rule 3"},
};
}
public ObservableCollection<Rule> Rules { get; private set; }
private Rule selectedRule;
public Rule SelectedRule
{
get { return selectedRule; }
set
{
selectedRule = value;
}
}
}
}
If you'd like to add text at the end of each line in-place (in the same file), you can use -i
parameter, for example:
sed -i'.bak' 's/$/:80/' foo.txt
However -i

So you can consider using ex
(which is equivalent to vi -e
/vim -e
):
ex +"%s/$/:80/g" -cwq foo.txt
which will add :80
to each line, but sometimes it can append it to blank lines.
So better method is to check if the line actually contain any number, and then append it, for example:
ex +"g/[0-9]/s/$/:80/g" -cwq foo.txt
If the file has more complex format, consider using proper regex, instead of [0-9]
.
Example: ajshdjashdjashdlasdlhdlSTARTasdasdsdaasdENDaknsdklansdlknaldknaaklsdn
1) START\w*END
return: STARTasdasdsdaasdEND - will give you words between START and END
2) START\d*END
return: START12121212END - will give you numbers between START and END
3) START\d*_\d*END
return: START1212_1212END - will give you numbers between START and END having _
If you want to change a color to single column try this:
dataGridView1.EnableHeadersVisualStyles = false;
dataGridView1.Columns[0].HeaderCell.Style.BackColor = Color.Magenta;
dataGridView1.Columns[1].HeaderCell.Style.BackColor = Color.Yellow;
Try this one if you want to create a virtual column "age" within a select statement:
select brand, name, "10" as age from cars...
I had existing tsconfig files for 4 existing projects in my solution. After upgrading to vs2017 I experienced this problem. It was fixed by adding the (supposedly default) include and exclude sections to the files, as described by NicoJuicy.
You can retrieve it from the post object like so:
global $post;
$post->post_name;
I've just been fighting with this today. Let's call the behavior of removing the extra line breaks "continuation." A little experimenting finds the following behavior:
Please note that I tried all of this with Outlook 2007. YMMV.
So if possible, end all bullet items with a sentence-terminating punctuation mark, a tab, or even three spaces.
use zip
columns = zip(*rows) #transpose rows to columns
print columns[0] #print the first column
#you can also do more with the columns
print columns[1] # or print the second column
columns.append([7,7,7]) #add a new column to the end
backToRows = zip(*columns) # now we are back to rows with a new column
print backToRows
you can also use numpy
a = numpy.array(a)
print a[:,0]
Edit: zip object is not subscriptable. It need to be converted to list to access as list:
column = list(zip(*row))
I had the same exception on Tomcat.. I found another problem - when i use wsimport over maven plugin to generate stubs for more then 1 WSDLs - class ObjectFactory
(stubs references to this class) contains methods ONLY for one wsdl. So you should merge all methods in one ObjectFactory
class (for each WSDL) or generate each wsdl stubs in different directories (there will be separates ObjectFactory
classes). It solves problem for me with this exception..J
You need to use command:
git config --global core.editor "'C:\Program Files\Microsoft VS Code\code.exe' -n -w"
Make sure you can start your editor from Git Bash
If you want to use Code.exe with short path, you can do this by adding the following line to your .bash_profile:
alias vscode="C:/Program\ Files/Microsoft\ VS\ Code/Code.exe"
And now, you can call it using only vscode
command(or whatever you named it)
Some additional info:
Setup will add Visual Studio Code to your %PATH%, so from the console you can type 'code' to open VS Code on that folder. You will need to restart your console after the installation for the change to the %PATH% environmental variable to take effect.

The LTrim function to remove leading spaces and the RTrim function to remove trailing spaces from a string variable. It uses the Trim function to remove both types of spaces and means before and after spaces of string.

The type attribute is used to define the MIME type within the HTML document. Depending on what DOCTYPE you use, the type value is required in order to validate the HTML document.
The language attribute lets the browser know what language you are using (Javascript vs. VBScript) but is not necessarily essential and, IIRC, has been deprecated.
The indexes capable of placing a unique key constraint on a table are PRIMARY
and UNIQUE
indexes.
To remove the unique key constraint on a column but keep the index, you could remove and recreate the index with type INDEX
.
Note that it is a good idea for all tables to have an index marked PRIMARY
.
I know there's a lot of answers here, but they all seem a bit confusing. So after doing some research from the Java oracle study guide, I've come up with three different scenarios of when to use && or &. The three scenarios are logical AND, bitwise AND, and boolean AND.
Logical AND:
Logical AND (aka Conditional AND) uses the && operator. It's short-circuited meaning: if the left operand is false, then the right operand will not be evaluated.
Example:
int x = 0;
if (false && (1 == ++x) {
System.out.println("Inside of if");
}
System.out.println(x); // "0"
In the above example the value printed to the console of x will be 0, because the first operand in the if statement is false, hence java has no need to compute (1 == ++x) therefore x will not be computed.
Bitwise AND: Bitwise AND uses the & operator. It's used to preform a bitwise operation on the value. It's much easier to see what's going on by looking at operation on binary numbers ex:
int a = 5; // 5 in binary is 0101
int b = 12; // 12 in binary is 1100
int c = a & b; // bitwise & preformed on a and b is 0100 which is 4
As you can see in the example, when the binary representations of the numbers 5 and 12 are lined up, then a bitwise AND preformed will only produce a binary number where the same digit in both numbers have a 1. Hence 0101 & 1100 == 0100. Which in decimal is 5 & 12 == 4.
Boolean AND: Now the boolean AND operator behaves similarly and differently to both the bitwise AND and logical AND. I like to think of it as preforming a bitwise AND between two boolean values (or bits), therefore it uses & operator. The boolean values can be the result of a logical expression too.
It returns either a true or false value, much like the logical AND, but unlike the logical AND it is not short-circuited. The reason being, is that for it to preform that bitwise AND, it must know the value of both left and right operands. Here's an ex:
int x = 0;
if (false & (1 == ++x) {
System.out.println("Inside of if");
}
System.out.println(x); //"1"
Now when that if statement is ran, the expression (1 == ++x) will be executed, even though the left operand is false. Hence the value printed out for x will be 1 because it got incremented.
This also applies to Logical OR (||), bitwise OR (|), and boolean OR (|) Hope this clears up some confusion.
You're using integer division.
Try 7.0/10
instead.
I think that you are looking for something like this:
function rightclick() {
var rightclick;
var e = window.event;
if (e.which) rightclick = (e.which == 3);
else if (e.button) rightclick = (e.button == 2);
alert(rightclick); // true or false, you can trap right click here by if comparison
}
(http://www.quirksmode.org/js/events_properties.html)
And then use the onmousedown even with the function rightclick() (if you want to use it globally on whole page you can do this <body onmousedown=rightclick(); >
This just allow positive integers.
^[0-9]*[1-9][0-9]*$
You can do it using only the shell, no need for tr

I use this as part of my utils. With this we can not only set shadow but also can get a rounded corner for any UIView
. Also you could set what color shadow you prefer. Normally black is preferred but sometimes, when the background is non-white you might want something else. Here's what I use -
in utils.m
+ (void)roundedLayer:(CALayer *)viewLayer
radius:(float)r
shadow:(BOOL)s
{
[viewLayer setMasksToBounds:YES];
[viewLayer setCornerRadius:r];
[viewLayer setBorderColor:[RGB(180, 180, 180) CGColor]];
[viewLayer setBorderWidth:1.0f];
if(s)
{
[viewLayer setShadowColor:[RGB(0, 0, 0) CGColor]];
[viewLayer setShadowOffset:CGSizeMake(0, 0)];
[viewLayer setShadowOpacity:1];
[viewLayer setShadowRadius:2.0];
}
return;
}
To use this we need to call this - [utils roundedLayer:yourview.layer radius:5.0f shadow:YES];
It would be better to have a check before getting the string.
$newstring = substr($dynamicstring, -7);
if characters are greater then 7 return last 7 characters else return the provided string.
or do this if you need to return message or error if length is less then 7
$newstring = (strlen($dynamicstring)>7)?substr($dynamicstring, -7):"message";
You should remember when to use everyone and that is it
the href is used with links
<a href="#"></a>
<link rel="stylesheet" href="style.css" />
the src is used with scripts and images
<img src="the_image_link" />
<script type="text/javascript" src="" />
the url is used generally in CSS to include something, for exemple to add a background image
selector { background-image: url('the_image_link'); }
In a project I worked at we solved this problem by implement something we called 'Batch' requests. We defined a path /batch
where we accepted json in the following format:
[
{
path: '/docs',
method: 'post',
body: {
doc_number: 1,
binder: 1
}
},
{
path: '/docs',
method: 'post',
body: {
doc_number: 5,
binder: 8
}
},
{
path: '/docs',
method: 'post',
body: {
doc_number: 6,
binder: 3
}
},
]
The response have the status code 207 (Multi-Status) and looks like this:
[
{
path: '/docs',
method: 'post',
body: {
doc_number: 1,
binder: 1
}
status: 200
},
{
path: '/docs',
method: 'post',
body: {
error: {
msg: 'A document with doc_number 5 already exists'
...
}
},
status: 409
},
{
path: '/docs',
method: 'post',
body: {
doc_number: 6,
binder: 3
},
status: 200
},
]
You could also add support for headers in this structure. We implemented something that proved useful which was variables to use between requests in a batch, meaning we can use the response from one request as input to another.
Facebook and Google have similar implementations:
https://developers.google.com/gmail/api/guides/batch
https://developers.facebook.com/docs/graph-api/making-multiple-requests
When you want to create or update a resource with the same call I would use either POST or PUT depending on the case. If the document already exist, do you want the entire document to be:
In case you want the behavior from alternative 1 you should use a POST and in case you want the behavior from alternative 2 you should use PUT.
http://restcookbook.com/HTTP%20Methods/put-vs-post/
As people already suggested you could also go for PATCH, but I prefer to keep API's simple and not use extra verbs if they are not needed.
Just after your Page_Load add this:
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
Note that I don't do anything in the function.

Coming from someone who has tried a number of "C# IDEs" on the Mac, your best bet is to install a virtual desktop with Windows and Visual Studio. It really is the best development IDE out there for .NET, nothing even comes close.
On a related note: I hate XCode.
Update: Use Xamarin Studio. It's solid.
You can use isin
method:
In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})
In [2]: df
Out[2]:
A B
0 5 1
1 6 2
2 3 3
3 4 5
In [3]: df[df['A'].isin([3, 6])]
Out[3]:
A B
1 6 2
2 3 3
And to get the opposite use ~
:
In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
A B
0 5 1
3 4 5
It uses commas as separators. So you can either set sep=","
or just use read.csv
:
x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593 9
The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table
thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):
State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582
And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table
with the default quote
argument (but not read.csv
):
01,089,24,033,MD,Prince George's County,13,30,1040
Here's an alternative way of tackling the problem:
Instead of trying to "fix it in post" why don't you truncate the description before the table needs to try and fit it into its columns? I did it like this:
<ng-container matColumnDef="description">
<th mat-header-cell *matHeaderCellDef> {{ 'Parts.description' | translate }} </th>
<td mat-cell *matCellDef="let element">
{{(element.description.length > 80) ? ((element.description).slice(0, 80) + '...') : element.description}}
</td>
</ng-container>
So I first check if the array is bigger than a certain length, if Yes then truncate and add '...' otherwise pass the value as is. This enables us to still benefit from the auto-spacing the table does :)
I have run through this. My case was more involved. The project was packaged fine from maven command line.
Couple of things I made. 1. One class has many imports that confused eclipse. Cleaning them fixed part of the problem 2. One case was about a Setter, pressing F3 navigating to that Setter although eclipse complained it is not there. So I simply retyped it and it worked fine (even for all other Setters)
I am still struggling with Implicit super constructor Item() is undefined for default constructor. Must define an explicit constructor"
var foo = [ { "a" : "1" }, { "b" : "2" }, { "a" : "1" } ];
var bar = _.map(_.groupBy(foo, function (f) {
return JSON.stringify(f);
}), function (gr) {
return gr[0];
}
);
Lets break this down. First lets group the array items by their stringified value
var grouped = _.groupBy(foo, function (f) {
return JSON.stringify(f);
});
grouped
looks like:
{
'{ "a" : "1" }' = [ { "a" : "1" } { "a" : "1" } ],
'{ "b" : "2" }' = [ { "b" : "2" } ]
}
Then lets grab the first element from each group
var bar = _.map(grouped, function(gr)
return gr[0];
});
bar
looks like:
[ { "a" : "1" }, { "b" : "2" } ]
Put it all together:
var foo = [ { "a" : "1" }, { "b" : "2" }, { "a" : "1" } ];
var bar = _.map(_.groupBy(foo, function (f) {
return JSON.stringify(f);
}), function (gr) {
return gr[0];
}
);
Instead of myFile.js write your files like myFile.mjs. This extension comes with all the goodies of es6, but I mean I recommend you to you webpack and Babel
The "d.ts" file is used to provide typescript type information about an API that's written in JavaScript. The idea is that you're using something like jQuery or underscore, an existing javascript library. You want to consume those from your typescript code.
Rather than rewriting jquery or underscore or whatever in typescript, you can instead write the d.ts file, which contains only the type annotations. Then from your typescript code you get the typescript benefits of static type checking while still using a pure JS library.
You can use the datapart to maintain time date type and you can compare it to another time.
Check below example:
declare @fromtime time = '09:30'
declare @totime time
SET @totime=CONVERT(TIME, CONCAT(DATEPART(HOUR, GETDATE()),':', DATEPART(MINUTE, GETDATE())))
if @fromtime <= @totime
begin print 'true' end
else begin print 'no' end
Mac users just open /Users/(USERNAME)/.bash_profile
this file in a editor.
and add this line to add path.
export PATH="/Users/myuser/Library/Android/sdk/platform-tools":$PATH
this is the default path if you install adb via studio. and dont forget to change the username in this line.
The always @* would never trigger as no Right hand arguments change. Why not use a wire with assign?
module top (
input wire clk,
output wire [7:0] led
);
wire [7:0] data_reg ;
assign data_reg = 8'b10101011;
assign led = data_reg;
endmodule
If you actually want a flop where you can change the value, the default would be in the reset clause.
module top
(
input clk,
input rst_n,
input [7:0] data,
output [7:0] led
);
reg [7:0] data_reg ;
always @(posedge clk or negedge rst_n) begin
if (!rst_n)
data_reg <= 8'b10101011;
else
data_reg <= data ;
end
assign led = data_reg;
endmodule
Hope this helps

As an alternative to @Mark Byers' approach, you can use while True
:

while True: # infinite loop
n = raw_input("\n\nTrue, False or Correct?: ")
if n == "Correct":
break # stops the loop
elif n == "True":
# etc.

Those are called #include guards.
Once the header is included, it checks if a unique value (in this case HEADERFILE_H
) is defined. Then if it's not defined, it defines it and continues to the rest of the page.
When the code is included again, the first ifndef
fails, resulting in a blank file.
That prevents double declaration of any identifiers such as types, enums and static variables.
and the convolution is defined through a multiplication in transform domain:

It selects all elements where the class name contains the string "span"
somewhere. There's also ^=
for the beginning of a string, and $=
for the end of a string. Here's a good reference for some CSS selectors.
I'm only familiar with the bootstrap classes spanX
where X is an integer, but if there were other selectors that ended in span
, it would also fall under these rules.
It just helps to apply blanket CSS rules.

To merge the sets in the array Sets, you can do
var Sets = [set1, set2, set3];
var merged = new Set([].concat(...Sets.map(set => Array.from(set))));
It is slightly mysterious to me why the following, which should be equivalent, fails at least in Babel:
var merged = new Set([].concat(...Sets.map(Array.from)));
I wrote my self a helper method to get patterns for this.
public static String getPattern(int month) {
String first = "MMMM dd";
String last = ", yyyy";
String pos = (month == 1 || month == 21 || month == 31) ? "'st'" : (month == 2 || month == 22) ? "'nd'" : (month == 3 || month == 23) ? "'rd'" : "'th'";
return first + pos + last;
}
and then we can call it as
LocalDate localDate = LocalDate.now();//For reference
int month = localDate.getDayOfMonth();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern(getPattern(month));
String date = localDate.format(formatter);
System.out.println(date);
the output is

To get the selected value of a spinner you can follow this example.
Create a nested class that implements AdapterView.OnItemSelectedListener. This will provide a callback method that will notify your application when an item has been selected from the Spinner.
Within "onItemSelected" method of that class, you can get the selected item:
public class YourItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
String selected = parent.getItemAtPosition(pos).toString();
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}
Finally, your ItemSelectedListener needs to be registered in the Spinner:
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
If the seq
command available on your system:
for i in `seq 2 $max`
do
echo "output: $i"
done
If not, then use poor man's seq
with perl
:
seq=`perl -e "\$,=' ';print 2..$max"`
for i in $seq
do
echo "output: $i"
done
Watch those quote marks.
I resolved this by clearing App Data.
Cypress documentation admits that App Data can get corrupted:
Cypress maintains some local application data in order to save user preferences and more quickly start up. Sometimes this data can become corrupted. You may fix an issue you have by clearing this app data.
cypress open
File
-> View App Data
cy
whose content should look something
like this: production
all.log
browsers
bundles
cache
projects
proxy
state.json
cy

I know its not relevant to this post but might help others converting HTML to PDF on client side. This is a simple solution if you use kendo. It also preserves the css (most of the cases).
var generatePDF = function() {_x000D_
kendo.drawing.drawDOM($("#formConfirmation")).then(function(group) {_x000D_
kendo.drawing.pdf.saveAs(group, "Converted PDF.pdf");_x000D_

For end of line use:
git diff --ignore-space-at-eol
Instead of what are you using currently:
git diff -w (--ignore-all-space)
For start of line... you are out of luck if you want a built in solution.
However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".
With a React Native running in the emulator,
Press ctrl+m (for Linux, I suppose it's the same for Windows and ?+m for Mac OS X)
or run the following in terminal:
adb shell input keyevent 82
This should work.
using System.Drawing.Printing;
...
PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "The printer name"; // Load the appropriate printer's setting
After that, the various properties of PrinterSettings can be read.
Note that ps.isValid()
can see if the printer actually exists.
Edit: One additional comment. Microsoft recommends you use a PrintDocument and modify its PrinterSettings rather than creating a PrinterSettings directly.
In the question you have mentioned the user as root, one thing I should mention is that the instance ID is not dependent on the user.
For Node developers,
var meta = new AWS.MetadataService();
meta.request("/latest/meta-data/instance-id", function(err, data){
console.log(data);
});
I've written scripts before that simply use telnet to connect to port 80, then transmit the text:
HTTP/1.0 GET /index.html
followed by two CR/LF sequences.
Provided you get back some form of HTTP response, you can generally assume the site is functioning.
I know this is a jQuery
related question, but now days with JS ES6 things are much easier. Since there is no pure javascript
answer, I thought I could add a simple pure javascript
solution to this, which in my opinion is much cleaner, by using the fetch()
API. This a modern way to implements network requests. In your case, since you already have a form element we can simply use it to build our request.
const form = document.forms["orderproductForm"];
const formInputs = form.getElementsByTagName("input");
let formData = new FormData();
for (let input of formInputs) {
formData.append(input.name, input.value);
}
fetch(form.action,
{
method: form.method,
body: formData
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.log(error.message))
.finally(() => console.log("Done"));
Use a try catch block like below:
try {
const phoneNumber = this.phoneUtil.parseAndKeepRawInput(value, this.countryCode);
}catch(e){}
Prior answers focused on nominal data (e.g. unordered). If there is a reason to impose order for an ordinal variable, then one would use:
# Transform to category
df['zipcode_category'] = df['zipcode_category'].astype('category')
# Add ordered category
df['zipcode_ordered'] = df['zipcode_category']
# Setup the ordering
df.zipcode_ordered.cat.set_categories(
new_categories = [90211, 90210], ordered = True, inplace = True
)
# Output IDs
df['zipcode_ordered_id'] = df.zipcode_ordered.cat.codes
print(df)
# zipcode_category zipcode_ordered zipcode_ordered_id
# 90210 90210 1
# 90211 90211 0
More details on setting ordered categories can be found at the pandas website:
https://pandas.pydata.org/pandas-docs/stable/user_guide/categorical.html#sorting-and-order
Repartition: Shuffle the data into a NEW number of partitions.
Eg. Initial data frame is partitioned in 200 partitions.
df.repartition(500)
: Data will be shuffled from 200 partitions to new 500 partitions.
Coalesce: Shuffle the data into existing number of partitions.
df.coalesce(5)
: Data will be shuffled from remaining 195 partitions to 5 existing partitions.

This works in Firefox 3.0, but not in MSIE 8, nor in Opera 9.62:
jQuery('#destinations').children('option[value="1"]').hide();
jQuery('#destinations').children('option[value="1"]').css('display','none');
But rather hiding an option, one can simply disable it:
jQuery('#destinations').val('2');
jQuery('#destinations').children('option[value="1"]').attr('disabled','disabled');
The first of the the two lines above is for Firefox and pass focus to the 2nd option (assuming it has value="2"). If we omit it, the option is disabled, but the still displays the "enabled" option before we drop it down. Hence, we pass focus to another option to avoid this.
You need the modal in your HTML. When the delete button is clicked it popup the modal. It's also important to prevent the click of that button from submitting the form. When the confirmation is clicked the form will submit.

This is absolutely possible. Although you shouldn't do it unless you know what you are dealing with. Took me about 2 days to figure it out. Here is a stored procedure where i enter: ---database name (schema name is "_" for readability) ---table name ---column ---column data type (column added is always null, otherwise you won't be able to insert) ---the position of the new column.
Since I'm working with tables from SAM toolkit (and some of them have > 80 columns) , the typical variable won't be able to contain the query. That forces the need of external file. Now be careful where you store that file and who has access on NTFS and network level.
Cheers!

The following works for mercurial by only committing if there are changes. So the build only fails if the commit fails.
hg id | grep "+" || exit 0
hg commit -m "scheduled commit"
find out what the date was 5 days ago from today in php
$date = strtotime(date("Y-m-d", strtotime("-5 day")));
find out what the date was n days ago from today in php
$date = strtotime(date("Y-m-d", strtotime("-n day")));
You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.
mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )
mysql $link
generally means, the resource object of the established mysqli connection to query the database.
So there are two ways of solving this problem
mysqli_query();
$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql");
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));
Or, Using mysql_query()
(This is now obselete)
$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());
As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .
See it might be worked -------
UPDATE table_name SET column_name=replace(column_name, ' ', '') //Remove white space
UPDATE table_name SET column_name=replace(column_name, '\n', '') //Remove newline
UPDATE table_name SET column_name=replace(column_name, '\t', '') //Remove all tab
Thanks Subroto
This is what I would do:
// num is your number
// amount is your percentage
function per(num, amount){
return num*amount/100;
}
...
<html goes here>
...
alert(per(10000, 35.8));
Right, click on the project. Go to Maven -> Update Project.
The dependencies will automatically be installed.
I suggest just use the Path.GetFullPath()
string tagetFileFullNameToBeChecked;
try
{
Path.GetFullPath(tagetFileFullNameToBeChecked)
}
catch(AugumentException ex)
{
// invalid chars found
}
Check out Regular Expressions.
NOW()
, TODAY()
, RAND()
, or RANDBETWEEN()
formulasPress Backspace ? or Del on any empty cell to immediately trigger a recalculation of formulas depending on NOW()
, TODAY()
, RAND()
, or RANDBETWEEN()
(in all Sheets of the whole Spreadsheet, as usual).
(If no empty cell is at hand, you can delete a filled cell instead and then undo that with Ctrl+z.)
INDIRECT()
formulas are unfortunately not updated like this by default.
INDIRECT()
formulasYou can update a (range of) cells of INDIRECT()
formulas by pasting the range on itself:
You can use Ctrl+A to select the whole current Sheet in step 1.. But for large Sheets then the other 2 operations can take several seconds each.
A trick to know when the process of copying a large range has finished:
Copy some single cell before copying your range: The single cell losing its dotted border will be your notification of the large copy finishing.
`CREATE TRIGGER `category_before_ins_tr` BEFORE INSERT ON `category`

hide back button with bellow code...
[self.navigationItem setHidesBackButton:YES animated:YES];
or
[self.navigationItem setHidesBackButton:YES];
Also if you have custom UINavigationBar
then try bellow code
self.navigationItem.leftBarButtonItem = nil;
This is iteration using block approach:
NSDictionary *dict = @{@"key1":@1, @"key2":@2, @"key3":@3};
[dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
NSLog(@"%@->%@",key,obj);
// Set stop to YES when you wanted to break the iteration.
}];
With autocompletion is very fast to set, and you do not have to worry about writing iteration envelope.
Ok what you probably want will be provide to you by result of:
in CSS:
div { column-count: 2; }
in html:
<div> some text, bla bla bla </div>
In CSS you make div to split your paragraph on to column, you can make them 3, 4...
If you want to have many differend paragraf like that, then put id or class in your div:
You can't rely on order of dictionaries, but you may try this:
mydict['Apple'].items()[0][0]
If you want the order to be preserved you may want to use this: http://www.python.org/dev/peps/pep-0372/#ordered-dict-api
I worked a little bit the method that Rawling posted here to find more than one line in the same file until the end. This is what worked for me:
foreach (var line in File.ReadLines(pathToFile))
{
if (line.Contains("CustomerEN") && current == null)
{
current = new List<string>();
current.Add(line);
}
else if (line.Contains("CustomerEN") && current != null)
{
current.Add(line);
}
}
string s = String.Join(",", current);
MessageBox.Show(s);
You can't do it by C#, but you can edit MSIL.
IL code of your Main method:
.method private hidebysig static void Main() cil managed
{
.entrypoint
.maxstack 1
.locals init (
[0] class MsilEditing.A a)
L_0000: nop
L_0001: newobj instance void MsilEditing.B::.ctor()
L_0006: stloc.0
L_0007: ldloc.0
L_0008: callvirt instance void MsilEditing.A::X()
L_000d: nop
L_000e: ret
}
You should change opcode in L_0008 from callvirt to call
L_0008: call instance void MsilEditing.A::X()
It is a problem with Java InputStream. When the stream is read once the file offset position counter is moved to the end of file. On the subsequent read by using the same stream you'll get this error. So you have to close and reopen the stream again or call inputStream.reset()
to reset the offset counter to its initial position.
You can use full datetime
variables with timedelta
, and by providing a dummy date then using time
to just get the time value.
For example:
import datetime
a = datetime.datetime(100,1,1,11,34,59)
b = a + datetime.timedelta(0,3) # days, seconds, then other fields.
print(a.time())
print(b.time())
results in the two values, three seconds apart:
11:34:59
11:35:02
You could also opt for the more readable
b = a + datetime.timedelta(seconds=3)
if you're so inclined.
If you're after a function that can do this, you can look into using addSecs
below:
import datetime
def addSecs(tm, secs):
fulldate = datetime.datetime(100, 1, 1, tm.hour, tm.minute, tm.second)
fulldate = fulldate + datetime.timedelta(seconds=secs)
return fulldate.time()
a = datetime.datetime.now().time()
b = addSecs(a, 300)
print(a)
print(b)
This outputs:
09:11:55.775695
09:16:55
You can ignore the peer dependency warnings by using the --force flag with Angular cli when updating dependencies.
ng update @angular/cli @angular/core --force
For a full list of options, check the docs: https://angular.io/cli/update
Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.
A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt
and jshint
.
These lines add more meaning
Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.
Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:
There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.
Please Note that grunt plugin is also an npm package.
Question-1
When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json
It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.
Question-2
When should I ever install packages explicitly like that without adding them to the file that manages dependencies
It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request
, then you have two options:
OR
npm install --save request
--save
options adds the dependency to package.json file as well. If you don't specify --save
option, it will only download the package but the json file will be unaffected.
You can do this either way, there will not be a substantial difference.
Type.GetType("namespace.qualified.TypeName")
only works when the type is found in either mscorlib.dll or the currently executing assembly.
If neither of those things are true, you'll need an assembly-qualified name:
Type.GetType("namespace.qualified.TypeName, Assembly.Name")
Since you are using Access to compose the query, you have to stick to Access's version of SQL.
To choose between several different return values, use the switch() function. So to translate and extend your example a bit:
select switch(
age > 40, 4,
age > 25, 3,
age > 20, 2,
age > 10, 1,
true, 0
) from demo
The 'true' case is the default one. If you don't have it and none of the other cases match, the function will return null.
The Office website has documentation on this but their example syntax is VBA and it's also wrong. I've given them feedback on this but you should be fine following the above example.
The documentation is here: http://docs.jquery.com/Ajax/jQuery.ajax
But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.
You would call it like this:
$.ajax({
url: 'mypage.html',
success: function(){
alert('success');
},
error: function(){
alert('failure');
}
});
I have shown the success and error function taking no arguments, but they can receive arguments.
The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.
The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.
The way I made object creator with auto list:
var list = [];
function saveToArray(x) {
list.push(x);
};
function newObject () {
saveToArray(this);
};
grep
matches, grep -v
does the inverse. If you need to "match A but not B" you usually use pipes:
grep "${PATT}" file | grep -v "${NOTPATT}"
