element in HTML represents preformatted text. Text within this element is typically displayed in a non-proportional font exactly as it is laid out in the file. Whitespaces inside this element are displayed as typed. It is usually used for showing computer code or output.
If you have jQuery enabled you can use an escapeXml function and not have to worry about escaping arrows or special characters.
<pre>
${fn:escapeXml('
<!-- all your code -->
')};
</pre>
<p style="text-indent: 5em;">
The first line of this paragraph will be indented about five characters, similar to a tabbed indent.

Starting Python 3.8
, and the introduction of assignment expressions (PEP 572) (:=
operator), we can now capture the condition value re.search(pattern, statement)
in a variable (let's all it match
) in order to both check if it's not None
and then re-use it within the body of the condition:
if match := re.search('I love (\w+)', statement):
print(f'He loves {match.group(1)}')
elif match := re.search("Ich liebe (\w+)", statement):
print(f'Er liebt {match.group(1)}')
elif match := re.search("Je t'aime (\w+)", statement):
print(f'Il aime {match.group(1)}')
You can use {}
arround your variable, to separate it from what's after:
echo "{$test}y"
As reference, you can take a look to the Variable parsing - Complex (curly) syntax section of the PHP manual.
The property file task is for editing properties files. It contains all sorts of nice features that allow you to modify entries. For example:
<propertyfile file="build.properties">
<entry key="build_number"
type="int"
operation="+"
value="1"/>
</propertyfile>
I've incremented my build_number
by one. I have no idea what the value was, but it's now one greater than what it was before.
<echo>
task to build a property file instead of <propertyfile>
. You can easily layout the content and then use <propertyfile>
to edit that content later on.Example:
<echo file="build.properties">
# Default Configuration
source.dir=1
dir.publish=1
# Source Configuration
dir.publish.html=1
</echo>
Example:
<propertyfile file="default.properties"
comment="Default Configuration">
<entry key="source.dir" value="1"/>
<entry key="dir.publish" value="1"/>
<propertyfile>
<propertyfile file="source.properties"
comment="Source Configuration">
<entry key="dir.publish.html" value="1"/>
<propertyfile>
<concat destfile="build.properties">
<fileset dir="${basedir}">
<include name="default.properties"/>
<include name="source.properties"/>
</fileset>
</concat>
<delete>
<fileset dir="${basedir}">
<include name="default.properties"/>
<include name="source.properties"/>
</fileset>
</delete>

The Mark Dickinson answer, although complete, didn't work with the float(52.15) case. After some tests, there is the solution that I'm using:
import decimal
def value_to_decimal(value, decimal_places):
decimal.getcontext().rounding = decimal.ROUND_HALF_UP # define rounding method
return decimal.Decimal(str(float(value))).quantize(decimal.Decimal('1e-{}'.format(decimal_places)))
(The conversion of the 'value' to float and then string is very important, that way, 'value' can be of the type float, decimal, integer or string!)
Hope this helps anyone.
That is because the if statements returns false since d doesn't contain b + a i.e "someonedamage"
Like this?
In LINQ:
var sortedList = originalList.OrderBy(foo => !foo.AVC)
.ToList();
Or in-place:
originalList.Sort((foo1, foo2) => foo2.AVC.CompareTo(foo1.AVC));
As Jon Skeet says, the trick here is knowing that false
is considered to be 'smaller' than true.
If you find that you are doing these ordering operations in lots of different places in your code, you might want to get your type Foo
to implement the IComparable<Foo>
and IComparable
interfaces.

Apple lifted the restrictions on non-Objective C/C/C++ apps -- you just can't load code that isn't in the app bundle.
MonoTouch lets you use .NET languages -- C# is directly supported, but if you have Windows, you can make assemblies in any .NET language and use it.
There are rumors that Apple is going to support other languages directly -- I keep hearing ruby, but they are just rumors.
I think Lua is being used for game logic on a lot of apps.
EDIT (in 2018): Generally you can use any language that you can get to compile for iOS or even install language interpreters. The main thing you cannot do is load code from the Internet that wasn't in the app bundle.
People do this all of the time anyway (see React Native apps loading JavaScript from servers), but, technically, it's not allowed. The main thing that will get you attention from Apple if you make some kind of App Store that loads whole App-like things.
EDIT (in 2020): from @Pylot in comments: I know this is a long time ago, but now at least technically you can load code that isn’t embedded in the app, as you can write with JavaScript using the webview. Not staying your answer is wrong or anything, I definitely agree with you. but I was looking for something and found this post on the way. Figured if anyone sees this it might help them out.
Because you send custom headers so your CORS request is not a simple request, so the browser first sends a preflight OPTIONS request to check that the server allows your request.
If you turn on CORS on the server then your code will work. You can also use JavaScript fetch instead (here)

If you are looking for something very accurate, you need to use some better tool than tf-idf. Universal sentence encoder is one of the most accurate ones to find the similarity between any two pieces of text. Google provided pretrained models that you can use for your own application without a need to train from scratch anything. First, you have to install tensorflow and tensorflow-hub:
pip install tensorflow
pip install tensorflow_hub
The code below lets you convert any text to a fixed length vector representation and then you can use the dot product to find out the similarity between them
import tensorflow_hub as hub
module_url = "https://tfhub.dev/google/universal-sentence-encoder/1?tf-hub-format=compressed"
# Import the Universal Sentence Encoder's TF Hub module
embed = hub.Module(module_url)
# sample text
messages = [
# Smartphones
"My phone is not good.",
"Your cellphone looks great.",
# Weather
"Will it snow tomorrow?",
"Recently a lot of hurricanes have hit the US",
# Food and health
"An apple a day, keeps the doctors away",
"Eating strawberries is healthy",
]
similarity_input_placeholder = tf.placeholder(tf.string, shape=(None))
similarity_message_encodings = embed(similarity_input_placeholder)
with tf.Session() as session:
session.run(tf.global_variables_initializer())
session.run(tf.tables_initializer())
message_embeddings_ = session.run(similarity_message_encodings, feed_dict={similarity_input_placeholder: messages})
corr = np.inner(message_embeddings_, message_embeddings_)
print(corr)
heatmap(messages, messages, corr)
and the code for plotting:
def heatmap(x_labels, y_labels, values):
fig, ax = plt.subplots()
im = ax.imshow(values)
# We want to show all ticks...
ax.set_xticks(np.arange(len(x_labels)))
ax.set_yticks(np.arange(len(y_labels)))
# ... and label them with the respective list entries
ax.set_xticklabels(x_labels)
ax.set_yticklabels(y_labels)
# Rotate the tick labels and set their alignment.
plt.setp(ax.get_xticklabels(), rotation=45, ha="right", fontsize=10,
rotation_mode="anchor")
# Loop over data dimensions and create text annotations.
for i in range(len(y_labels)):
for j in range(len(x_labels)):
text = ax.text(j, i, "%.2f"%values[i, j],
ha="center", va="center", color="w",
fontsize=6)
fig.tight_layout()
plt.show()
as you can see the most similarity is between texts with themselves and then with their close texts in meaning.
IMPORTANT: the first time you run the code it will be slow because it needs to download the model. if you want to prevent it from downloading the model again and use the local model you have to create a folder for cache and add it to the environment variable and then after the first time running use that path:
tf_hub_cache_dir = "universal_encoder_cached/"
os.environ["TFHUB_CACHE_DIR"] = tf_hub_cache_dir
# pointing to the folder inside cache dir, it will be unique on your system
module_url = tf_hub_cache_dir+"/d8fbeb5c580e50f975ef73e80bebba9654228449/"
embed = hub.Module(module_url)

It depends on what the integer is supposed to encode. You could convert the date to a number of milliseconds from some previous time. People often do this affixed to 12:00 am January 1 1970, or 1900, etc., and measure time as an integer number of milliseconds from that point. The datetime
module (or others like it) will have functions that do this for you: for example, you can use int(datetime.datetime.utcnow().timestamp())
.
If you want to semantically encode the year, month, and day, one way to do it is to multiply those components by order-of-magnitude values large enough to juxtapose them within the integer digits:
2012-06-13 --> 20120613 = 10,000 * (2012) + 100 * (6) + 1*(13)
def to_integer(dt_time):
return 10000*dt_time.year + 100*dt_time.month + dt_time.day
E.g.
In [1]: import datetime
In [2]: %cpaste
Pasting code; enter '--' alone on the line to stop or use Ctrl-D.
:def to_integer(dt_time):
: return 10000*dt_time.year + 100*dt_time.month + dt_time.day
: # Or take the appropriate chars from a string date representation.
:--
In [3]: to_integer(datetime.date(2012, 6, 13))
Out[3]: 20120613
If you also want minutes and seconds, then just include further orders of magnitude as needed to display the digits.
I've encountered this second method very often in legacy systems, especially systems that pull date-based data out of legacy SQL databases.
It is very bad. You end up writing a lot of hacky code for aligning dates, computing month or day offsets as they would appear in the integer format (e.g. resetting the month back to 1 as you pass December, then incrementing the year value), and boiler plate for converting to and from the integer format all over.
Unless such a convention lives in a deep, low-level, and thoroughly tested section of the API you're working on, such that everyone who ever consumes the data really can count on this integer representation and all of its helper functions, then you end up with lots of people re-writing basic date-handling routines all over the place.
It's generally much better to leave the value in a date context, like datetime.date
, for as long as you possibly can, so that the operations upon it are expressed in a natural, date-based context, and not some lone developer's personal hack into an integer.
Another approach is to (ab)use the PostgreSQL GUC mechanism to create variables. See this prior answer for details and examples.
You declare the GUC in postgresql.conf
, then change its value at runtime with SET
commands and get its value with current_setting(...)
.
I don't recommend this for general use, but it could be useful in narrow cases like the one mentioned in the linked question, where the poster wanted a way to provide the application-level username to triggers and functions.
I am not 100% sure where all of the other suggestions are trying to go, but the issue is basically related to the extension that you have on the file. If you save the file as a Excel 97/2003 workbook it will not allow you to see all million rows. Create a new sheet and save it as a workbook and you will see all million. Note: the extension will be .xlsx
Be careful when iterating over arrays!!
It is a common misconception that using the index of the element in the array is an acceptable way of suppressing the error you are probably familiar with:
Each child in an array should have a unique "key" prop.
However, in many cases it is not! This is anti-pattern that can in some situations lead to unwanted behavior.
key
propReact uses the key
prop to understand the component-to-DOM Element relation, which is then used for the reconciliation process. It is therefore very important that the key always remains unique, otherwise there is a good chance React will mix up the elements and mutate the incorrect one. It is also important that these keys remain static throughout all re-renders in order to maintain best performance.
That being said, one does not always need to apply the above, provided it is known that the array is completely static. However, applying best practices is encouraged whenever possible.
A React developer said in this GitHub issue:
- key is not really about performance, it's more about identity (which in turn leads to better performance). randomly assigned and changing values are not identity
- We can't realistically provide keys [automatically] without knowing how your data is modeled. I would suggest maybe using some sort of hashing function if you don't have ids
- We already have internal keys when we use arrays, but they are the index in the array. When you insert a new element, those keys are wrong.
In short, a key
should be:
key
propAs per the explanation above, carefully study the following samples and try to implement, when possible, the recommended approach.
<tbody>
{rows.map((row, i) => {
return <ObjectRow key={i} />;
})}
</tbody>
This is arguably the most common mistake seen when iterating over an array in React. This approach isn't technically "wrong", it's just... "dangerous" if you don't know what you are doing. If you are iterating through a static array then this is a perfectly valid approach (e.g. an array of links in your navigation menu). However, if you are adding, removing, reordering or filtering items, then you need to be careful. Take a look at this detailed explanation in the official documentation.
class MyApp extends React.Component {
constructor() {
super();
this.state = {
arr: ["Item 1"]
}
}
click = () => {
this.setState({
arr: ['Item ' + (this.state.arr.length+1)].concat(this.state.arr),
});
}
render() {
return(
<div>
<button onClick={this.click}>Add</button>
<ul>
{this.state.arr.map(
(item, i) => <Item key={i} text={"Item " + i}>{item + " "}</Item>
)}
</ul>
</div>
);
}
}
const Item = (props) => {
return (
<li>
<label>{props.children}</label>
<input value={props.text} />
</li>
);
}
ReactDOM.render(<MyApp />, document.getElementById("app"));

In this snippet we are using a non-static array and we are not restricting ourselves to using it as a stack. This is an unsafe approach (you'll see why). Note how as we add items to the beginning of the array (basically unshift), the value for each <input>
remains in place. Why? Because the key
doesn't uniquely identify each item.
In other words, at first Item 1
has key={0}
. When we add the second item, the top item becomes Item 2
, followed by Item 1
as the second item. However, now Item 1
has key={1}
and not key={0}
anymore. Instead, Item 2
now has key={0}
!!
As such, React thinks the <input>
elements have not changed, because the Item
with key 0
is always at the top!
So why is this approach only sometimes bad?
This approach is only risky if the array is somehow filtered, rearranged, or items are added/removed. If it is always static, then it's perfectly safe to use. For example, a navigation menu like ["Home", "Products", "Contact us"]
can safely be iterated through with this method because you'll probably never add new links or rearrange them.
In short, here's when you can safely use the index as key
:
Had we instead, in the snippet above, pushed the added item to the end of the array, the order for each existing item would always be correct.
<tbody>
{rows.map((row) => {
return <ObjectRow key={Math.random()} />;
})}
</tbody>
While this approach will probably guarantee uniqueness of the keys, it will always force react to re-render each item in the list, even when this is not required. This a very bad solution as it greatly impacts performance. Not to mention that one cannot exclude the possibility of a key collision in the event that Math.random()
produces the same number twice.
Unstable keys (like those produced by
Math.random()
) will cause many component instances and DOM nodes to be unnecessarily recreated, which can cause performance degradation and lost state in child components.
<tbody>
{rows.map((row) => {
return <ObjectRow key={row.uniqueId} />;
})}
</tbody>
This is arguably the best approach because it uses a property that is unique for each item in the dataset. For example, if rows
contains data fetched from a database, one could use the table's Primary Key (which typically is an auto-incrementing number).
The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys
componentWillMount() {
let rows = this.props.rows.map(item => {
return {uid: SomeLibrary.generateUniqueID(), value: item};
});
}
...
<tbody>
{rows.map((row) => {
return <ObjectRow key={row.uid} />;
})}
</tbody>
This is also a good approach. If your dataset does not contain any data that guarantees uniqueness (e.g. an array of arbitrary numbers), there is a chance of a key collision. In such cases, it is best to manually generate a unique identifier for each item in the dataset before iterating over it. Preferably when mounting the component or when the dataset is received (e.g. from props
or from an async API call), in order to do this only once, and not each time the component re-renders. There are already a handful of libraries out there that can provide you such keys. Here is one example: react-key-index.
This will work if youtube app installed. If not, a chooser will show up to select other application:
Uri uri = Uri.parse( "https://www.youtube.com/watch?v=bESGLojNYSo" );
uri = Uri.parse( "vnd.youtube:" + uri.getQueryParameter( "v" ) );
startActivity( new Intent( Intent.ACTION_VIEW, uri ) );

The most famous library to create some GUI in C language is certainly GTK.
With this library you can easily create some buttons (for your example). When a user clicks on the button, a signal is emitted and you can write a handler to do some actions.

Your regexp seems to validate both the file name and the extension. Is that what you need? I'll assume it's just the extension and would use a regexp like this:
\.(jpg|gif|doc|pdf)$
And set the matching to be case insensitive.
check your value which you want to store in integer column. I think this is greater then range of integer. if you want to store value greater then integer range. you should use bigint datatype

As I said in comments - you should always use parameters in your query - NEVER EVER concatenate together your SQL statements yourself.
Also: I would recommend to separate the click event handler from the actual code to insert the data.
So I would rewrite your code to be something like
In your web page's code-behind file (yourpage.aspx.cs
)
private void button1_Click(object sender, EventArgs e)
{
string connectionString = "Data Source=DELL-PC;initial catalog=AdventureWorks2008R2 ; User ID=sa;Password=sqlpass;Integrated Security=SSPI;";
InsertData(connectionString,
textBox1.Text.Trim(), -- first name
textBox2.Text.Trim(), -- last name
textBox3.Text.Trim(), -- user name
textBox4.Text.Trim(), -- password
Convert.ToInt32(comboBox1.Text), -- age
comboBox2.Text.Trim(), -- gender
textBox7.Text.Trim() ); -- contact
}
In some other code (e.g. a databaselayer.cs
):
private void InsertData(string connectionString, string firstName, string lastname, string username, string password
int Age, string gender, string contact)
{
// define INSERT query with parameters
string query = "INSERT INTO dbo.regist (FirstName, Lastname, Username, Password, Age, Gender,Contact) " +
"VALUES (@FirstName, @Lastname, @Username, @Password, @Age, @Gender, @Contact) ";
// create connection and command
using(SqlConnection cn = new SqlConnection(connectionString))
using(SqlCommand cmd = new SqlCommand(query, cn))
{
// define parameters and their values
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar, 50).Value = firstName;
cmd.Parameters.Add("@Lastname", SqlDbType.VarChar, 50).Value = lastName;
cmd.Parameters.Add("@Username", SqlDbType.VarChar, 50).Value = userName;
cmd.Parameters.Add("@Password", SqlDbType.VarChar, 50).Value = password;
cmd.Parameters.Add("@Age", SqlDbType.Int).Value = age;
cmd.Parameters.Add("@Gender", SqlDbType.VarChar, 50).Value = gender;
cmd.Parameters.Add("@Contact", SqlDbType.VarChar, 50).Value = contact;
// open connection, execute INSERT, close connection
cn.Open();
cmd.ExecuteNonQuery();
cn.Close();
}
}
Code like this:
I had this problem when installing a new SQL Server 2012 standalone Server.
Cause: When installing SQL Managemnt Tools it will install the VS Shell. It seems like this is all you need but this ist not enough! (it actually shows it will install VS) Strangly the path and the application are shown in windows put you can't open them without the error.
Fix: You need to also install "SQL Server Data Tools" via Feature Add with the SQL-Server.iso
Hope this helps someone... i took me quite a while.
I set the Advanced->Refspec field to refs/tags/[your tag name]
. This seems simpler than the various other suggestions for Refspec, but it worked just fine for me.
UPDATE 23/7/2014 - Actually, after further testing, it turns out this didn't work as expected. It appears that the HEAD version was still being checked out. Please undo this as the accepted answer. I ended up getting a working solution by following the post from gotgenes in this thread (30th March). The issue mentioned in that post of unnecessary triggering of builds was not an issue for me, as my job is triggered from an upstream job, not from polling SCM.
UPDATE APR-2018 - Note in the comments that this does work for one person, and agrees with Jenkins documentation.
You can quickly get to blur effect by doing the following.
// Add this to build.gradle app //
Compile ' com.github.jgabrielfreitas:BlurImageView:1.0.1 '
// Add to XML
<com.jgbrielfreitas.core.BlurImageView
android:id="@+id/iv_blur_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
//Add this to java
Import com.jgabrielfreitas.core.BlueImageView;
// Under public class *activity name * //
BlurImageView myBlurImage;
// Under Oncreate//
myBlurImage = (ImageView) findViewById(R.id.iv_blur_image)
MyBlurImage.setBlue(5)
I hope that helps someone
Just check if response[0]
is undefined:
if(response[0] !== undefined) { ... }
If you still need to explicitly check the title, do so after the initial check:
if(response[0] !== undefined && response[0].title !== undefined){ ... }
I had this same issue and when I had an incorrect IP for session.save_path for memcached sessions. Changing it to the correct IP fixed the problem.

You can use unionByName to make this:
df = df_1.unionByName(df_2)
unionByName is available since Spark 2.3.0.

All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.vehicals_details_row, parent, false);
Button deleteImageView = (Button) row.findViewById(R.id.DeleteImageView);
deleteImageView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//...
}
});
}
But you can get an issue - listView row not clickable. Solution:
android:focusable="true"
android:focusable="false"
This is my code for a function that gets the tasks and gets their names, also adding them into a list to be accessed from a list. It creates temp files with the data, reads the files and gets the task name with the .exe suffix, and arranges the files to be deleted when the program has exited with System.exit(0), it also hides the processes being used to get the tasks and also java.exe so that the user can't accidentally kill the process that runs the program all together.

Sometimes this happens because symlinks are not allowed in template settings:
Advanced > Developer > Template Settings > Allow Symlinks
You could just use a simple JavaScript regular expression to test for purely numeric characters:
/^[0-9]+$/.test(input);
This returns true if the input is numeric or false if not.
or for event keycode, simple use below :
// Allow: backspace, delete, tab, escape, enter, ctrl+A and .
if ($.inArray(e.keyCode, [46, 8, 9, 27, 13, 110, 190]) !== -1 ||
// Allow: Ctrl+A
(e.keyCode == 65 && e.ctrlKey === true) ||
// Allow: home, end, left, right
(e.keyCode >= 35 && e.keyCode <= 39)) {
// let it happen, don't do anything
return;
}
var charValue = String.fromCharCode(e.keyCode)
, valid = /^[0-9]+$/.test(charValue);
if (!valid) {
e.preventDefault();
}
You're right that the JetBrains help page isn't very clear. On OS X, you'll want to use the launcher at:
/Applications/PyCharm.app/Contents/MacOS/pycharm
Or, for community edition:
/Applications/PyCharm\ CE.app/Contents/MacOS/pycharm
Unfortunately, adding a symlink to this binary wouldn't work for me (the launcher would crash). Setting an alias worked, though. Add this in your .bash_profile
(or whatever shell you use):
alias pycharm="/Applications/PyCharm CE.app/Contents/MacOS/pycharm"
Then, you can run commands with simply pycharm
.
With this you can do things like open a project:
pycharm ~/repos/my-project
Or open a specific line of a file in a project:
pycharm ~/repos/my-project --line 42 ~/repos/my-project/script.py
Or view the diff of two files (they don't need to be part of a project):
pycharm ~/some_file.txt ~/Downloads/some_other_file.txt
Note that I needed to pass absolute paths to those files or PyCharm couldn't find them..
If you're running your PHP script from the command-line, passthru()
has one large benefit. It will let you execute scripts/programs such as vim
, dialog
, etc, letting those programs handle control and returning to your script only when they are done.
If you use system()
or exec()
to execute those scripts/programs, it simply won't work.
Gotcha: For some reason, you can't execute less
with passthru()
in PHP.
Try this solution and it worked. this problem is caused because ADB is unable to connect to the android servers to fetch updates. (If at home try turning off firewall)
http
, not https
)This should work immediately.
Not a queue example, but extremely simple :)
class MyHouse {
private boolean pizzaArrived = false;
public void eatPizza(){
synchronized(this){
while(!pizzaArrived){
wait();
}
}
System.out.println("yumyum..");
}
public void pizzaGuy(){
synchronized(this){
this.pizzaArrived = true;
notifyAll();
}
}
}
Some important points:
1) NEVER do
if(!pizzaArrived){
wait();
}
Always use while(condition), because
while(!pizzaExists){ wait(); }
.2) You must hold the lock (synchronized) before invoking wait/nofity. Threads also have to acquire lock before waking.
3) Try to avoid acquiring any lock within your synchronized block and strive to not invoke alien methods (methods you don't know for sure what they are doing). If you have to, make sure to take measures to avoid deadlocks.
4) Be careful with notify(). Stick with notifyAll() until you know what you are doing.
5)Last, but not least, read Java Concurrency in Practice!
With VSTS the url is, When you copy git clone url from vsts you always get
https://orgname@dev.azure.com/org/project/_git/repo
Replace orgname@ with your alternate username that you would have created in VSTS -> profile -> Security.
final git url -
https://alternateusername@dev.azure.com/org/project/_git/repo
You can define the _CRT_SECURE_NO_WARNINGS symbol to suppress them and undefine it to reinstate them back.
abs(x-y)
will do exactly what you're looking for:
In [1]: abs(1-2)
Out[1]: 1
In [2]: abs(2-1)
Out[2]: 1
as all said this will do so
new ArrayList<>(Arrays.asList("1","2","3","4"));
and the common newest way to create array is observableArrays
ObservableList: A list that allows listeners to track changes when they occur.
for Java SE you can try
FXCollections.observableArrayList(new Element(1), new Element(2), new Element(3));
that is according to Oracle Docs
observableArrayList() Creates a new empty observable list that is backed by an arraylist. observableArrayList(E... items) Creates a new observable array list with items added to it.
also in Java 9 it's a little bit easy:
List<String> list = List.of("element 1", "element 2", "element 3");
MySQL does allow NULL
values for datetime
fields. I just tested it:
mysql> create table datetimetest (testcolumn datetime null default null);
Query OK, 0 rows affected (0.10 sec)
mysql> insert into datetimetest (testcolumn) values (null);
Query OK, 1 row affected (0.00 sec)
mysql> select * from datetimetest;
+------------+
| testcolumn |
+------------+
| NULL |
+------------+
1 row in set (0.00 sec)
I'm using this version:
mysql> select version();
+-----------+
| version() |
+-----------+
| 5.0.45 |
+-----------+
1 row in set (0.03 sec)
EDIT #1: I see in your edit that the error message you are getting in PHP indicates that you are passing an empty string (i.e. ''
), not null
. An empty string is different than null
and is not a valid datetime
value which is why you are getting that error message. You must pass the special sql keyword null
if that's what you mean. Also, don't put any quotes around the word null
. See my insert
statement above for an example of how to insert null
.
EDIT #2: Are you using PDO? If so, when you bind your null param, make sure to use the [PDO::PARAM_NULL][1]
type when binding a null
. See the answer to this stackoverflow question on how to properly insert null
using PDO.
I found that it was necessary to enter the architecture names by hand:
I don't know why this was necessary, i.e. why these values were not inherited from Xcode itself. But as soon as I did this, the problem went away.
Make sure enable this settings from iOS 9:
App Transport Security Settings in Info.plist to ensure loading image from URL so that it will allow download image and set it.
And write this code:
NSURL *url = [[NSURL alloc]initWithString:@"http://feelgrafix.com/data/images/images-1.jpg"];
NSData *data =[NSData dataWithContentsOfURL:url];
quickViewImage.image = [UIImage imageWithData:data];
Try this code
final EditText editText = findViewById(R.id.name); // your edittext id in xml
Button submit = findViewById(R.id.submit_button); // your button id in xml
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{
String string = editText.getText().toString();
Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
}
});
There's also ShortGuid - A shorter and url friendly GUID class in C#. It's available as a Nuget. More information here.
PM> Install-Package CSharpVitamins.ShortGuid
Usage:
Guid guid = Guid.NewGuid();
ShortGuid sguid1 = guid; // implicitly cast the guid as a shortguid
Console.WriteLine(sguid1);
Console.WriteLine(sguid1.Guid);
This produces a new guid, uses that guid to create a ShortGuid, and displays the two equivalent values in the console. Results would be something along the lines of:
ShortGuid: FEx1sZbSD0ugmgMAF_RGHw
Guid: b1754c14-d296-4b0f-a09a-030017f4461f
Use the isSelected method.
You can also use an ItemListener so you'll be notified when it's checked or unchecked.
This can be achieved using TextEditingController
.
To have an initial value you can add
TextEditingController _controller = TextEditingController(text: 'initial value');
or
If you are using TextFormField
you have a initialValue
property there. Which basically provides this initialValue
to the controller automatically.
TextEditingController _controller = TextEditingController();
TextFormField(
controller: _controller,
initialValue: 'initial value'
)
To clear the text you can use
_controller.clear()
method.
Yes, 1 byte does encode a character (inc spaces etc) from the ASCII set. However in data units assigned to character encoding it can and often requires in practice up to 4 bytes. This is because English is not the only character set. And even in English documents other languages and characters are often represented. The numbers of these are very many and there are very many other encoding sets, which you may have heard of e.g. BIG-5, UTF-8, UTF-32. Most computers now allow for these uses and ensure the least amount of garbled text (which usually means a missing encoding set.) 4 bytes is enough to cover these possible encodings. I byte per character does not allow for this and in use it is larger often 4 bytes per possible character for all encodings, not just ASCII. The final character may only need a byte to function or be represented on screen, but requires 4 bytes to be located in the rather vast global encoding "works".

Sure you can query your Database with SHOW TABLES
and then loop through all the records but that is extra code lines and work.

I had the same problem and it might look so easy but it solved my problem. I have tried all the solutions recommended here but there was no problem just a day ago. So I thought the problem might be about the Session data. I tried to stop and run apache and mysql services but it didn't work also. Then I realized there are buttons on phpMyAdmin just below its logo on the left side. The button next to "Home"; "Empty Session Data" solved all of my problems.
After much aggravation this is what I have found to work"simply". First thing, I am using MYSQL Workbench and the import would not work as it should, as the import dump file would always revert to the original schema name. I spent several hours trying every thing to no avail,all for a spelling error. I solved the issue by opening one of the .sql dump files in notebook and hand editing the typo's of the schema name, take care to rename all instances schema name has three in the beginning, save the file and then import. this worked perfectly for me and hope that it will help others looking for the simple answer to changing database names/schema names. One more tip that I have found true, when programs do not do as they should go to the "source" literally find the source code. Hope this helps someone
Low rep so they wont let me comment on the prior/post answer(it keeps changing rank or position), so I added it here. reverse engineering will work fine as long as there is no data in the sever table. if data exists and you try to update the server after the name change it will either pull an error or just create a new database/schema with no data, I know I tried ten times to no avail. The above works simply and avoids headaches, as one can review the SQL code for other errors if any or change table names or creation data. the .sql file is just a compiled SQL code so in theory one could copy and add it through PHP or the script console of the database management tool.

You can read here about the behaviour of attributes in many different browsers, including IE.
element.setAttribute()
should do the trick, even in IE. Did you try it? If it doesn't work, then maybe
element.attributeName = 'value'
might work.
You can do this by using CSS: JSFiddle
HTML:
<select>
<option>Text 1</option>
<option>Text 2</option>
<option>Text 3</option>
</select>
CSS:
select option:first-child { color:red; }
Or if you absolutely need to use JavaScript (not adviced for this): JSFiddle
JavaScript:
$(function() {
$("select option:first-child").addClass("highlight");
});
CSS:
.highlight { color:red; }
FrameLayout is designed to block out an area on the screen to display a single item. Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other. You can, however, add multiple children to a FrameLayout and control their position within the FrameLayout by assigning gravity to each child, using the
android:layout_gravity
attribute.Child views are drawn in a stack, with the most recently added child on top. The size of the FrameLayout is the size of its largest child (plus padding), visible or not (if the FrameLayout's parent permits).
A RelativeLayout is a very powerful utility for designing a user interface because it can eliminate nested view groups and keep your layout hierarchy flat, which improves performance. If you find yourself using several nested LinearLayout groups, you may be able to replace them with a single RelativeLayout.
(Current docs here)
A TableLayout consists of a number of
TableRow
objects, each defining a row (actually, you can have other children, which will be explained below). TableLayout containers do not display border lines for their rows, columns, or cells. Each row has zero or more cells; each cell can hold one View object. The table has as many columns as the row with the most cells. A table can leave cells empty. Cells can span columns, as they can in HTML.The width of a column is defined by the row with the widest cell in that column.
Note: Absolute Layout is deprecated.
From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.
The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.
If this issue is causing serious problems, here are a few things I would suggest:
Revert back to JDK 1.7.0_25 until a fix is added to the JDK.
Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.
Try the JDK early releases as they come out. One of them might fix your problem.
Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.
This was probably only in my case, but I had reloaded some files from a backup and things were not working, including this. After doing a full clean (Product > Clean or Shift + Command + K) it worked. Probably something got messed up in a precompiled header. Chances are that's not the problem for you, but it's worth a shot.
This can be resolved by specifying the specific column names desired from the specific table like so:
$c = Customer::leftJoin('orders', function($join) {
$join->on('customers.id', '=', 'orders.customer_id');
})
->whereNull('orders.customer_id')
->first([
'customers.id',
'customers.first_name',
'customers.last_name',
'customers.email',
'customers.phone',
'customers.address1',
'customers.address2',
'customers.city',
'customers.state',
'customers.county',
'customers.district',
'customers.postal_code',
'customers.country'
]);
I would like to add something.

This is how to install a normal MSI file silently:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"
Quick explanation:
/L*V "C:\Temp\msilog.log"= verbose logging at indicated path
/QN = run completely silently
/i = run install sequence
The msiexec.exe command line is extensive with support for a variety of options. Here is another overview of the same command line interface. Here is an annotated versions (was broken, resurrected via way back machine).
It is also possible to make a batch file a lot shorter with constructs such as for loops as illustrated here for Windows Updates.
If there are check boxes that must be checked during the setup, you must find the appropriate PUBLIC PROPERTIES attached to the check box and set it at the command line like this:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log" STARTAPP=1 SHOWHELP=Yes
These properties are different in each MSI. You can find them via the verbose log file or by opening the MSI in Orca, or another appropriate tool. You must look either in the dialog control section or in the Property table for what the property name is. Try running the setup and create a verbose log file first and then search the log for messages ala "Setting property..." and then see what the property name is there. Then add this property with the value from the log file to the command line.
Also have a look at how to use transforms to customize the MSI beyond setting command line parameters: How to make better use of MSI files
For the date, you can use datetime.date.today()
or datetime.datetime.now().date()
.
For the time, you can use datetime.datetime.now().time()
.
However, why have separate fields for these in the first place? Why not use a single DateTimeField
?
You can always define helper functions on the model that return the .date()
or .time()
later if you only want one or the other.
For me the git:// just doesn't work through the proxy although the https:// does. This caused some bit of headache because I was running scripts that all used git:// so I couldn't just easily change them all. However I found this GEM
git config --global url."https://github.com/".insteadOf git://github.com/
While you can't use floating point division in Bash you can use fixed point division. All that you need to do is multiply your integers by a power of 10 and then divide off the integer part and use a modulo operation to get the fractional part. Rounding as needed.
#!/bin/bash
n=$1
d=$2
# because of rounding this should be 10^{i+1}
# where i is the number of decimal digits wanted
i=4
P=$((10**(i+1)))
Pn=$(($P / 10))
# here we 'fix' the decimal place, divide and round tward zero
t=$(($n * $P / $d + ($n < 0 ? -5 : 5)))
# then we print the number by dividing off the interger part and
# using the modulo operator (after removing the rounding digit) to get the factional part.
printf "%d.%0${i}d\n" $(($t / $P)) $(((t < 0 ? -t : t) / 10 % $Pn))
Try playing around with this method:
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView
layout:(UICollectionViewLayout*)collectionViewLayout
insetForSectionAtIndex:(NSInteger)section {
UIEdgeInsets insets = UIEdgeInsetsMake(?, ?, ?, ?);
return insets;
}
You normally forward the request to a JSP for display. JSP is a view technology which provides a template to write plain vanilla HTML/CSS/JS in and provides ability to interact with backend Java code/variables with help of taglibs and EL. You can control the page flow with taglibs like JSTL. You can set any backend data as an attribute in any of the request, session or application scope and use EL (the ${}
things) in JSP to access/display them. You can put JSP files in /WEB-INF
folder to prevent users from directly accessing them without invoking the preprocessing servlet.
Kickoff example:
@WebServlet("/hello")
public class HelloWorldServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String message = "Hello World";
request.setAttribute("message", message); // This will be available as ${message}
request.getRequestDispatcher("/WEB-INF/hello.jsp").forward(request, response);
}
}
And /WEB-INF/hello.jsp
look like:
<!DOCTYPE html>
<html lang="en">
<head>
<title>SO question 2370960</title>
</head>
<body>
<p>Message: ${message}</p>
</body>
</html>
When opening http://localhost:8080/contextpath/hello this will show
Message: Hello World
in the browser.

File name: ".whatever you want"
(with the leading dot)
You can do it in Explorer (in Windows 7) by adding a period at the end of the filename:
.whatever you want.
Windows will automatically remove the trailing dot when you validate.
The comma got eaten by the quotes!
This part:
("username," visitorName);
Should be this:
("username", visitorName);
Aside: For pasting code into the console, you can paste them in one line at a time to help you pinpoint where things went wrong ;-)
Note that the ansible
command doesn't collect facts, but the ansible-playbook
command does. When running ansible -m setup
, the setup module happens to run the fact collection so you get the facts, but running ansible -m command
does not. Therefore the facts aren't available. This is why the other answers include playbook YAML files and indicate the lookup works.
The MultiCell
is used for print text with multiple lines. It has the same atributes of Cell
except for ln
and link
.
$pdf->MultiCell( 200, 40, $reportSubtitle, 1);
What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).
MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])
You can read the full documentation here.
There are 2 options to find matching text; string.match
or string.find
.
Both of these perform a regex search on the string to find matches.
string.find()
string.find(subject string, pattern string, optional start position, optional plain flag)
Returns the startIndex
& endIndex
of the substring found.
The plain
flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger)
being interpreted as a regex capture group matching for tiger
, it instead looks for (tiger)
within a string.
Going the other way, if you want to regex match but still want literal special characters (such as .()[]+-
etc.), you can escape them with a percentage; %(tiger%)
.
You will likely use this in combination with string.sub
str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
string.match()
string.match(s, pattern, optional index)
Returns the capture groups found.
str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
If the bytes use an appropriate character encoding already; you could print them directly:
sys.stdout.buffer.write(data)
or
nwritten = os.write(sys.stdout.fileno(), data) # NOTE: it may write less than len(data) bytes
You need to use return value of replaceAll()
method. replaceAll()
does not replace the characters in the current string, it returns a new string with replacement.
- String objects are immutable, their values cannot be changed after they are created.
- You may use replace() instead of replaceAll() if you don't need regex.
String str = "abcd=0; efgh=1";
String replacedStr = str.replaceAll("abcd", "dddd");
System.out.println(str);
System.out.println(replacedStr);
outputs
abcd=0; efgh=1
dddd=0; efgh=1
A quick search using...
apt search Xlib.h
Turns up the package libx11-dev but you shouldn't need this for pure OpenGL programming. What tutorial are you using?
You can add Xlib.h to your system by running the following...
sudo apt install libx11-dev
I simply use
git fetch origin
to fetch the remote changes, and then I view both local and pending remote commits (and their associated changes) with the nice gitk tool involving the --all
argument like:
gitk --all
Really, there isn't. there are about a half-zillion different regex syntaxes; they seem to come down to Perl, EMACS/GNU, and AT&T in general, but I'm always getting surprised too.
Use Type.IsAssignableTo
(as of .NET 5.0):
typeof(MyType).IsAssignableTo(typeof(IMyInterface));
As stated in a couple of comments IsAssignableFrom may be considered confusing by being "backwards".
The xlsxwriter
library is great for creating .xlsx
files. The following snippet generates an .xlsx
file from a list of dicts while stating the order and the displayed names:
from xlsxwriter import Workbook
def create_xlsx_file(file_path: str, headers: dict, items: list):
with Workbook(file_path) as workbook:
worksheet = workbook.add_worksheet()
worksheet.write_row(row=0, col=0, data=headers.values())
header_keys = list(headers.keys())
for index, item in enumerate(items):
row = map(lambda field_id: item.get(field_id, ''), header_keys)
worksheet.write_row(row=index + 1, col=0, data=row)
headers = {
'id': 'User Id',
'name': 'Full Name',
'rating': 'Rating',
}
items = [
{'id': 1, 'name': "Ilir Meta", 'rating': 0.06},
{'id': 2, 'name': "Abdelmadjid Tebboune", 'rating': 4.0},
{'id': 3, 'name': "Alexander Lukashenko", 'rating': 3.1},
{'id': 4, 'name': "Miguel Díaz-Canel", 'rating': 0.32}
]
create_xlsx_file("my-xlsx-file.xlsx", headers, items)
Note 1 - I'm purposely not answering to the exact case the OP presented. Instead, I'm presenting a more generic solution IMHO most visitors seek. This question's title is well-indexed in search engines and tracks lots of traffic
Note 2 - If you're not using Python3.6 or newer, consider using
OrderedDict
inheaders
. Before Python3.6 the order indict
was not preserved.
Search for a null value by using \00
For example:
ldapsearch -D cn=admin -w pass -s sub -b ou=users,dc=acme 'manager=\00' uid manager
Make sure if you use the null value on the command line to use quotes around it to prevent the OS shell from sending a null character to LDAP. For example, this won't work:
ldapsearch -D cn=admin -w pass -s sub -b ou=users,dc=acme manager=\00 uid manager
There are various sites that reference this, along with other special characters. Example:
try:
git ls-files --error-unmatch <file name>
will exit with 1 if file is not tracked
My approach to the problem is similar to the way datayeah did it. I had a lot of hardcoded width and height values and the app looked fine on a specific device. So I got the screen height of the device and just created a factor to scale the hardcoded values.
double heightFactor = MediaQuery.of(context).size.height/708
where 708 is the height of the specific device.
npm pack
+ package.json
This is what worked for me:
module project
, execute npm pack
:This will build a <package-name>-<version>.tar.gz
file.
consumer project
Ideally you can put all such files in a tmp
folder in your consumer-project
root:
package.json
:"dependencies": {
"my-package": "file:/./tmp/my-package-1.3.3.tar.gz"
}
Install
the packages:npm install
or npm i
or yarn
consumer-project's node_modules
folder.Good Luck...
Try this:
$(":focus").each(function() {
alert("Focused Elem_id = "+ this.id );
});
So you know the key, value pair that you want to delete in advance? It's just much clearer to do this, then:
table.delete(key);
for (K key: table.keySet()) {
// do whatever you need to do with the rest of the keys
}
You could use reduce:
const arr = ["q", "w", "w", "e", "i", "u", "r"]
arr.reduce((acc, cur) => {
if(acc[cur]) {
acc.duplicates.push(cur)
} else {
acc[cur] = true //anything could go here
}
}, { duplicates: [] })
Result would look like this:
{ ...Non Duplicate Values, duplicates: ["w"] }
That way you can do whatever you want with the duplicate values!
String[] str = {};
But
return {};
won't work as the type information is missing.
You did not supply the file handling code, but I assume you made the same mistake everyone does when first writing such a thing: the filewatcher event will be raised as soon as the file is created. However, it will take some time for the file to be finished. Take a file size of 1 GB for example. The file may be created by another program (Explorer.exe copying it from somewhere) but it will take minutes to finish that process. The event is raised at creation time and you need to wait for the file to be ready to be copied.
You can wait for a file to be ready by using this function in a loop.
Add set nocount on
to the beginning of the stored proc (if you're on SQL Server). I just solved this problem in my own work and it was caused by intermediate results, such as "1203 Rows Affected"
, being loaded into the Recordset
I was trying to use.
I haven't had to do this, so take this with a grain of salt and a big helping of "test, test, test".
What happens if (in a safe controlled test environment) you directly modify the Host
column in the mysql.user
and probably mysql.db
tables? (E.g., with an update
statement.) I don't think MySQL uses the user's host as part of the password encoding (the PASSWORD
function doesn't suggest it does), but you'll have to try it to be sure. You may need to issue a FLUSH PRIVILEGES
command (or stop and restart the server).
For some storage engines (MyISAM, for instance), you may also need to check/modify the .frm
file any views that user has created. The .frm
file stores the definer, including the definer's host. (I have had to do this, when moving databases between hosts where there had been a misconfiguration causing the wrong host to be recorded...)
If your DBMS supports the notation, you need a separate set of parentheses for each row:
INSERT INTO Data(Col1) VALUES ('Hello'), ('World');
The cross-referenced question shows examples for inserting into two columns.
Alternatively, every SQL DBMS supports the notation using separate statements, one for each row to be inserted:
INSERT INTO Data (Col1) VALUES ('Hello');
INSERT INTO Data (Col1) VALUES ('World');
For me, changing the ownership of /var/lib/mongodb and /tmp/mongodb-27017.sock to mongodb was the way to go.
Just do:
sudo chown -R mongodb:mongodb /var/lib/mongodb
and then:
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock
and then start or restart the mongodb server:
sudo systemctl start mongod
or
sudo systemctl restart mongod
and check the status
sudo systemctl status mongod
jQuery provides several selectors (full list) in order to make the queries you are looking for work. To address your question "In other cases is it possible to use other selectors like "contains, less than, greater than, etc..."." you can also use contains, starts with, and ends with to look at these html5 data attributes. See the full list above in order to see all of your options.
The basic querying has been covered above, and using John Hartsock's answer is going to be the best bet to either get every data-company element, or to get every one except Microsoft (or any other version of :not
).
In order to expand this to the other points you are looking for, we can use several meta selectors. First, if you are going to do multiple queries, it is nice to cache the parent selection.
var group = $('ul[data-group="Companies"]');
Next, we can look for companies in this set who start with G
var google = $('[data-company^="G"]',group);//google
Or perhaps companies which contain the word soft
var microsoft = $('[data-company*="soft"]',group);//microsoft
It is also possible to get elements whose data attribute's ending matches
var facebook = $('[data-company$="book"]',group);//facebook
//stored selector_x000D_
var group = $('ul[data-group="Companies"]');_x000D_
_x000D_
//data-company starts with G_x000D_
var google = $('[data-company^="G"]',group).css('color','green');_x000D_
_x000D_
//data-company contains soft_x000D_
var microsoft = $('[data-company*="soft"]',group).css('color','blue');_x000D_
_x000D_
//data-company ends with book_x000D_
var facebook = $('[data-company$="book"]',group).css('color','pink');
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<ul data-group="Companies">_x000D_
<li data-company="Microsoft">Microsoft</li>_x000D_
<li data-company="Google">Google</li>_x000D_
<li data-company ="Facebook">Facebook</li>_x000D_

This way you can create Observable from data, in my case I need to maintain shopping cart:
service.ts
export class OrderService {
cartItems: BehaviorSubject<Array<any>> = new BehaviorSubject([]);
cartItems$ = this.cartItems.asObservable();
// I need to maintain cart, so add items in cart
addCartData(data) {
const currentValue = this.cartItems.value; // get current items in cart
const updatedValue = [...currentValue, data]; // push new item in cart
if(updatedValue.length) {
this.cartItems.next(updatedValue); // notify to all subscribers
}
}
}
Component.ts
export class CartViewComponent implements OnInit {
cartProductList: any = [];
constructor(
private order: OrderService
) { }
ngOnInit() {
this.order.cartItems$.subscribe(items => {
this.cartProductList = items;
});
}
}
This works for me.
json.load() accepts file object, parses the JSON data, populates a Python dictionary with the data and returns it back to you.
Suppose JSON file is like this:
{
"emp_details":[
{
"emp_name":"John",
"emp_emailId":"[email protected]"
},
{
"emp_name":"Aditya",
"emp_emailId":"[email protected]"
}
]
}
import json
# Opening JSON file
f = open('data.json',)
# returns JSON object as
# a dictionary
data = json.load(f)
# Iterating through the json
# list
for i in data['emp_details']:
print(i)
# Closing file
f.close()
#Output:
{'emp_name':'John','emp_emailId':'[email protected]'}
{'emp_name':'Aditya','emp_emailId':'[email protected]'}
You may want to try View.getRootView()
.
Add each line of the code to a variable and then write the variable to your inner HTML. See below:
var div = document.createElement('div');
div.setAttribute('class', 'post block bc2');
var str = "First Line";
str += "Second Line";
str += "So on, all of your lines";
div.innerHTML = str;
document.getElementById('posts').appendChild(div);

The problem is that
find . -mmin -60
outputs:
.
./file1
./file2
Note the line with one dot?
That makes ls
list the whole directory exactly the same as when ls -l .
is executed.
One solution is to list only files (not directories):
find . -mmin -60 -type f | xargs ls -l
But it is better to use directly the option -exec of find:
find . -mmin -60 -type f -exec ls -l {} \;
Or just:
find . -mmin -60 -type f -ls
Which, by the way is safe even including directories:
find . -mmin -60 -ls
From documentation:
Matplotlib can only read PNGs natively. Further image formats are supported via the optional dependency on Pillow.
So in case of PNG
we may use plt.imread()
. In other cases it's probably better to use Pillow
directly.
If you would like to use awk
then this would work too
awk -F= '{$2="xxx";print}' OFS="\=" filename
The trivial solution is to put those newlines where you want them.
var="a
b
c"
Yes, that's an assignment wrapped over multiple lines.
However, you will need to double-quote the value when interpolating it, otherwise the shell will split it on whitespace, effectively turning each newline into a single space (and also expand any wildcards).
echo "$p"
Generally, you should double-quote all variable interpolations unless you specifically desire the behavior described above.
If you want to implement autocomplete functionality, then Completion Suggester is the most neat solution. The next blog post contains a very clear description how this works.
In two words, it's an in-memory data structure called an FST which contains valid suggestions and is optimised for fast retrieval and memory usage. Essentially, it is just a graph. For instance, and FST containing the words hotel
, marriot
, mercure
, munchen
and munich
would look like this:
Why not just run this: No need for special permissions
SELECT
name,
object_id,
create_date,
modify_date
FROM
sys.tables
WHERE
name like '%yourTablePattern%'
ORDER BY
modify_date
If you are styling calc in a GWT project, its parser might not parse calc for you as it did not for me... the solution is to wrap it in a css literal like this:
height: literal("-moz-calc(100% - (20px + 30px))");
height: literal("-webkit-calc(100% - (20px + 30px))");
height: literal("calc(100% - (20px + 30px))");
If you aren't allowing the column to be Null you need to provide a default to populate existing rows. e.g.
ALTER TABLE dbo.YourTbl ADD
newcol int NOT NULL CONSTRAINT DF_YourTbl_newcol DEFAULT 0
On Enterprise Edition this is a metadata only change since 2012
You need a SMPT Server in order for
... mail($to,$subject,$message,$headers);
to work.
You could try light weight SMTP servers like xmailer
For my PHP application the solution was include utf8_decode function for each variable get in $_POST
.
Ex: (SERVER SIDE)
if( strtoupper($_SERVER['REQUEST_METHOD']) == "POST" ){
$variable = htmlentities($_POST['variable']); // wrong
$variable = htmlentities( utf8_decode($_POST['variable']) ); // right
}
Abraços!!! (Bye Bye!!!)
Then you'd want to do this instead:
print str(int(1.0/3.0*100))+'%'
The .0
denotes them as floats and int()
rounds them to integers afterwards again.
Set the Screen orientation to portrait in Manifest file under the activity Tag.
it works for me after changing MaxPermSize=512M to MaxPermSize=256M
You want your if
check to be:
{% if not loop.last %}
,
{% endif %}
Note that you can also shorten the code by using If Expression:
{{ ", " if not loop.last else "" }}
If you worked the correct way to create your migrations by using the command Add-Migration "Name_Of_Migration"
then you can do the following to get a clean start (reset, with loss of data, of course):
Update-database -TargetMigration:0
Normally your DB is empty now since the down methods were executed.
Update-database
This will recreate your DB to your current migration
If the database is InnoDB then it might be a better idea to use foreign keys and cascade on delete, this would do what you want and also result in no redundant data being stored.
For this example however I don't think you need the first s:
DELETE s
FROM spawnlist AS s
INNER JOIN npc AS n ON s.npc_templateid = n.idTemplate
WHERE n.type = "monster";
It might be a better idea to select the rows before deleting so you are sure your deleting what you wish to:
SELECT * FROM spawnlist
INNER JOIN npc ON spawnlist.npc_templateid = npc.idTemplate
WHERE npc.type = "monster";
You can also check the MySQL delete syntax here: http://dev.mysql.com/doc/refman/5.0/en/delete.html
hash = {"apple" => "fruit", "carrot" => "vegetable"}
array = hash.keys #=> ["apple", "carrot"]
it's that simple
You can do it manually. (I know, that that isn't great solution, but..)
use while
loop till the result
hasn't a value
kickOff().then(function(result) {
while(true){
if (result === undefined) continue;
else {
$("#output").append(result);
return;
}
}
});
Example:
<input type="button" value="Click me" id="myButton">
<script>
var myButton = document.getElementById("myButton");
var test = "zipzambam";
myButton.onclick = function(eventObject) {
if (!eventObject) {
eventObject = window.event;
}
if (!eventObject.target) {
eventObject.target = eventObject.srcElement;
}
alert(eventObject.target);
alert(test);
};
(function(myMessage) {
alert(myMessage);
})("Hello");
</script>
I prefer a simple adaptation of csgillespie's method, foregoing the need of a function definition:
d[apply(d!=0, 1, all),]
where d
is your data frame.
Chances are that you've not included the header file that declares system()
.
In order to be able to compile C++ code that uses functions which you don't (manually) declare yourself, you have to pull in the declarations. These declarations are normally stored in so-called header files that you pull into the current translation unit using the #include
preprocessor directive. As the code does not #include
the header file in which system()
is declared, the compilation fails.
To fix this issue, find out which header file provides you with the declaration of system()
and include that. As mentioned in several other answers, you most likely want to add #include <cstdlib>

3x the same plot with differnt y-labeling
Minimal example
import numpy as np
import matplotlib as mpl
import matplotlib.pylab as plt
from matplotlib.ticker import FormatStrFormatter
fig, axs = mpl.pylab.subplots(1, 3)
xs = np.arange(10)
ys = 1 + xs ** 2 * 1e-3
axs[0].set_title('default y-labeling')
axs[0].scatter(xs, ys)
axs[1].set_title('custom y-labeling')
axs[1].scatter(xs, ys)
axs[2].set_title('x, pos arguments')
axs[2].scatter(xs, ys)
fmt = lambda x, pos: '1+ {:.0f}e-3'.format((x-1)*1e3, pos)
axs[1].yaxis.set_major_formatter(mpl.ticker.FuncFormatter(fmt))
fmt = lambda x, pos: 'x={:f}\npos={:f}'.format(x, pos)
axs[2].yaxis.set_major_formatter(mpl.ticker.FuncFormatter(fmt))
You can also use 'real'-functions instead of lambdas, of course. https://matplotlib.org/3.1.1/gallery/ticks_and_spines/tick-formatters.html
To track down the correct parameters you need to go first to ?plot.default
, which refers you to ?par
and ?axis
:
plot(1, 1 ,xlab="x axis", ylab="y axis", pch=19,
col.lab="red", cex.lab=1.5, # for the xlab and ylab
col="green") # for the points
Use Meta-b / Meta-f to move backward/forward by a word respectively.
In OSX, Meta translates as ESC, which sucks.
But alternatively, you can open terminal preferences -> settings -> profile -> keyboard and check "use option as meta key"
You can place a text-box to the report and add an expression with the following value in it:
="Report generation date: " & Format(Globals!ExecutionTime,"dd/MM/yyyy h:mm:ss tt" )

This is just a warning and it doesn't make problem for your project to run, you can just ignore it and continue coding. But if you're obsessed about clean coding, same as me, you have two options:
f1
then type trim trailing whitespace
.Following will give you active connections/ queries in postgres DB-
SELECT
pid
,datname
,usename
,application_name
,client_hostname
,client_port
,backend_start
,query_start
,query
,state
FROM pg_stat_activity
WHERE state = 'active';
You may use 'idle' instead of active to get already executed connections/queries.
Just use div { padding: 20px; }
and substract 40px
from your original div
width.
Like Philip Wills pointed out, you can also use box-sizing
instead of substracting 40px
:
div {
padding: 20px;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
The -moz-box-sizing
is for Firefox.
One other answer to the same error message (this just fixed my problem) is that the System drive was low on disk space. Meaning about 700kb free. Deleting a lot of unused stuff on this really old server and then restarting IIS and the website (probably only IIS was necessary) cause the problem to disappear for me.
I'm sure the other answers are more useful for most people, but for a quick fix, just make sure that the System drive has some free space.
It sounds like you are going to be storing the value that input field contains after the form is submitted, which means you are using a scripting language. I would use it instead of JavaScript as most scripting languages have better time/date formatting options. In PHP you could do something like this:
<input id="date" name="date" value="<?php echo date("M j, Y - g:i"); ?>"/>
Which would fill the field with "Jun 16, 2009 - 8:58"
This is a stab in the dark, but maybe do you need to wrap your JSON arguments; like say something like this:
data: "{'Ids':[{'Id1':'2'},{'Id2':'2'}]}"
Make sure your JSON is properly formed?
Java 8 supports default methods in interfaces. And in JDK 8 a lot of old interfaces now have new default methods. For example, now in CharSequence we have chars and codePoints methods.
If source level of your project is lower than 1.8, then compiler doesn't allow you to use default methods in interfaces. So it cannot compile classes that directly on indirectly depend on this interfaces.
If I get your problem right, then you have two solutions. First solution is to rollback to JDK 7, then you will use old CharSequence interface without default methods. Second solution is to set source level of your project to 1.8, then your compiler will not complain about default methods in interfaces.
NB: Should you want the year to be based on some reference date, the code below calculates the dates for the between
statement:
declare @referenceTime datetime = getutcdate()
select *
from myTable
where SomeDate
between dateadd(year, year(@referenceTime) - 1900, '01-01-1900') --1st Jan this year (midnight)
and dateadd(millisecond, -3, dateadd(year, year(@referenceTime) - 1900, '01-01-1901')) --31st Dec end of this year (just before midnight of the new year)
Similarly, if you're using a year value, swapping year(@referenceDate)
for your reference year's value will work
declare @referenceYear int = 2010
select *
from myTable
where SomeDate
between dateadd(year,@referenceYear - 1900, '01-01-1900') --1st Jan this year (midnight)
and dateadd(millisecond, -3, dateadd(year,@referenceYear - 1900, '01-01-1901')) --31st Dec end of this year (just before midnight of the new year)
I'm not sure that I understand what you mean by "rights of ownership".
If User B owns a stored procedure, User B can grant User A permission to run the stored procedure
GRANT EXECUTE ON b.procedure_name TO a
User A would then call the procedure using the fully qualified name, i.e.
BEGIN
b.procedure_name( <<list of parameters>> );
END;
Alternately, User A can create a synonym in order to avoid having to use the fully qualified procedure name.
CREATE SYNONYM procedure_name FOR b.procedure_name;
BEGIN
procedure_name( <<list of parameters>> );
END;
Another option is snprintf
:
double pi = 3.1415926;
std::string s(16, '\0');
auto written = std::snprintf(&s[0], s.size(), "%.2f", pi);
s.resize(written);
Demo. Error handling should be added, i.e. checking for written < 0
.
After some fiddling with a script I came to this action. Copy and save it in a .bat file:
FOR /F "usebackq tokens=5" %%i IN (`netstat -aon ^| find "3306"`) DO taskkill /F /PID %%i
Change 'find "3306"' in the port number which needs to be free. Then run the file as administrator. It will kill all the processes running on this port.
Just use this code as the basis of a simple JQuery plugin.
$.extend({
distinct : function(anArray) {
var result = [];
$.each(anArray, function(i,v){
if ($.inArray(v, result) == -1) result.push(v);
});
return result;
}
});
Use as so:
$.distinct([0,1,2,2,3]);

Valentin Rocher's method works if you've extended your view, but if you're using an event listener, use this:
view.setOnTouchListener(new OnTouchListener()
{
public boolean onTouch(View v, MotionEvent event)
{
Toast toast = Toast.makeText(
getApplicationContext(),
"View touched",
Toast.LENGTH_LONG
);
toast.show();
return true;
}
});
// Obtain MotionEvent object
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis() + 100;
float x = 0.0f;
float y = 0.0f;
// List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
int metaState = 0;
MotionEvent motionEvent = MotionEvent.obtain(
downTime,
eventTime,
MotionEvent.ACTION_UP,
x,
y,
metaState
);
// Dispatch touch event to view
view.dispatchTouchEvent(motionEvent);
For more on obtaining a MotionEvent object, here is an excellent answer: Android: How to create a MotionEvent?
Content insets solve the problem of having content that goes underneath other parts of the User Interface and yet still remains reachable using scroll bars. In other words, the purpose of the Content Inset is to make the interaction area smaller than its actual area.
Consider the case where we have three logical areas of the screen:
TOP BUTTONS
TEXT
BOTTOM TAB BAR
and we want the TEXT to never appear transparently underneath the TOP BUTTONS, but we want the Text to appear underneath the BOTTOM TAB BAR and yet still allow scrolling so we could update the text sitting transparently under the BOTTOM TAB BAR.
Then we would set the top origin to be below the TOP BUTTONS, and the height to include the bottom of BOTTOM TAB BAR. To gain access to the Text sitting underneath the BOTTOM TAB BAR content we would set the bottom inset to be the height of the BOTTOM TAB BAR.
Without the inset, the scroller would not let you scroll up the content enough to type into it. With the inset, it is as if the content had extra "BLANK CONTENT" the size of the content inset. Blank text has been "inset" into the real "content" -- that's how I remember the concept.
Well, here's an example for overloaded constructors.
public class Employee
{
private String name;
private int age;
public Employee()
{
System.out.println("We are inside Employee() constructor");
}
public Employee(String name)
{
System.out.println("We are inside Employee(String name) constructor");
this.name = name;
}
public Employee(String name, int age)
{
System.out.println("We are inside Employee(String name, int age) constructor");
this.name = name;
this.age = age;
}
public Employee(int age)
{
System.out.println("We are inside Employee(int age) constructor");
this.age = age;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public int getAge()
{
return age;
}
public void setAge(int age)
{
this.age = age;
}
}
In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.
Here are some resources which throw more light on constructor overloading in java,
Here is an awesome and precise explanation I found.
TIMESTAMP used to track changes of records, and update every time when the record is changed. DATETIME used to store specific and static value which is not affected by any changes in records.
TIMESTAMP also affected by different TIME ZONE related setting. DATETIME is constant.
TIMESTAMP internally converted a current time zone to UTC for storage, and during retrieval convert the back to the current time zone. DATETIME can not do this.
TIMESTAMP is 4 bytes and DATETIME is 8 bytes.
TIMESTAMP supported range: ‘1970-01-01 00:00:01' UTC to ‘2038-01-19 03:14:07' UTC DATETIME supported range: ‘1000-01-01 00:00:00' to ‘9999-12-31 23:59:59'

The answer is NO you can't. Why?
Because the LDAP standard describes a LDAP-SEARCH as kind of function with 4 parameters:
You are interested in the filter. You've got a summary here (it's provided by Microsoft for Active Directory, it's from a standard). The filter is composed, in a boolean way, by expression of the type Attribute Operator Value
.
So the filter you give does not mean anything.
On the theoretical point of view there is ExtensibleMatch that allows buildind filters on the DN path, but it's not supported by Active Directory.
As far as I know, you have to use an attribute in AD to make the distinction for users in the two OUs.
It can be any existing discriminator attribute, or, for example the attribute called OU which is inherited from organizationalPerson
class. you can set it (it's not automatic, and will not be maintained if you move the users) with "staff" for some users and "vendors" for others and them use the filter:
(&(objectCategory=person)(|(ou=staff)(ou=vendors)))
I know this is a question regarding the CSS.Tooltips library. However, for anyone else came here resulting from google search "tooltip for input box" like I did, here is the simplest way:
<input title="This is the text of the tooltip" value="44"/>
an abstract method must be call override in derived class other wise it will give compile-time error and in virtual you may or may not override it's depend if it's good enough use it
Example:
abstract class twodshape
{
public abstract void area(); // no body in base class
}
class twodshape2 : twodshape
{
public virtual double area()
{
Console.WriteLine("AREA() may be or may not be override");
}
}
Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure
show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.
Try to convert Prize into decimal format...
import java.math.BigDecimal;
import java.math.RoundingMode;
public class Bigdecimal {
public static boolean isEmpty (String st) {
return st == null || st.length() < 1;
}
public static BigDecimal bigDecimalFormat(String Preis){
//MathContext mi = new MathContext(2);
BigDecimal bd = new BigDecimal(0.00);
bd = new BigDecimal(Preis);
return bd.setScale(2, RoundingMode.HALF_UP);
}
public static void main(String[] args) {
String cost = "12.12";
if (!isEmpty(cost) ){
try {
BigDecimal intCost = bigDecimalFormat(cost);
System.out.println(intCost);
List<Book> books = bookService.findBooksCheaperThan(intCost);
} catch (NumberFormatException e) {
System.out.println("This is not a number");
System.out.println(e.getMessage());
}
}
}
}
One can use these simple javascript within the input tag.
<input type="text" name="your_name" value="your_value"
onfocus="this.setSelectionRange(this.value.length, this.value.length);"
autofocus />

I am using WebAPI 3 and was facing the same issue. The issue has resolve as @Rytis added his solution. And I think in WebAPI 3, we don't need to define method RegisterWebApi
.
My change was only in web.config file and is working.
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="GET, POST" />
</customHeaders>

Thanks for you solution @Rytis!
Try this until a non-no answer appears:

this.child;
interestingProperty = "5";
...
}
function child() {
this.parent;
...
}
a = new parent();
a.child = new child();
a.child.parent = a; // this gives the child a reference to its parent
alert(a.interestingProperty+" === "+a.child.parent.interestingProperty);
Look at this tutorial or this one, they are both pretty simple. If you are interested in an alternative this is how you do file I/O in C.
Some things to keep in mind, use single quotes '
when dealing with single characters, and double "
for strings. Also it is a bad habit to use global variables when not necessary.

Android supports string formatting using HTML tags in the strings xml. So the following would work:
<string name="label_testinghtmltags"><u>This text has an underscore</u></string>
Then you just use it as you normally would. You can see more in the documentation here
Update:
To further expand on the answer, the documentation says:
... the
format(String, Object...)
andgetString(int, Object...)
methods strip all the style information from the string. . The work-around to this is to write the HTML tags with escaped entities, which are then recovered with fromHtml(String), after the formatting takes place
For example, the resulting string from the following code snippet will not show up as containing underscored elements:
<string name="html_bold_test">This <u>%1$s</u> has an underscore</string>
String result = getString(R.string.html_bold_test, "text")
However the result from the following snippet would contain underscores:
<string name="html_bold_test">This <u> %1$s </u> has an underscore</string>
String result = Html.fromHtml(getString(R.string.html_bold_test, "text"))
You can name cells. This is done by clicking the Name Box (that thing next to the formula bar which says "A1" for example) and typing a name, such as, "myvar". Now you can use that name instead of the cell reference:
= myvar*25
In android gradle 0.4.0 you can just do:
println System.env.HOME
classpath com.android.tools.build:gradle-experimental:0.4.0

ACBD18DB4CC2F85CEDEF654FCCC4A4D8
It would return NULL but if taken as BIGINT would show the number
I used this solution for same problem.
HTML code should change to this:
<input type="text" name="username" />
<input type="text" name="password" id="txt_password" />
and jQuery code should be in document.ready

$(this).attr('type','password');
});

You can use the toolchain file mechanism of cmake for this purpose, see e.g. here. You write a toolchain file for each compiler containing the corresponding definitions. At config time, you run e.g
cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/clang-toolchain.cmake ..
and all the compiler information will be set during the project() call from the toolchain file. Though in the documentation is mentionend only in the context of cross-compiling, it works as well for different compilers on the same system.
That's it! There is no command for deleting your virtual environment. Simply deactivate it and rid your application of its artifacts by recursively removing it.
Note that this is the same regardless of what kind of virtual environment you are using. virtualenv
, venv
, Anaconda environment, pyenv
, pipenv
are all based the same principle here.

in viewDidLoadA little extension to the above answers. The trailing >
directs the input into the file, overwriting existing content. However, one particularly convenient use is the double arrow >>
that appends, adding your new content to the end of the file, as in:
cat <<EOF >> /etc/fstab
data_server:/var/sharedServer/authority/cert /var/sharedFolder/sometin/authority/cert nfs
data_server:/var/sharedServer/cert /var/sharedFolder/sometin/vsdc/cert nfs
EOF
This extends your fstab
without you having to worry about accidentally modifying any of its contents.

If you develop for Android KitKat or newer, you could also use a switch statement (see: Android coding with switch (String)). e.g.
switch(yourString)
{
case "john":
//do something for john
case "mary":
//do something for mary
}
$text='<span style="font-weight: bold;">Foo</span>';
$text=preg_replace( '/<span style="font-weight: bold;">(.*?)<\/span>/', '<strong>$1</strong>',$text);
Note: only work for your example.
Use the following statement: SHOW INDEX FROM your_table
And then check the result for the fields: row["Table"], row["Key_name"]
Make sure you write "Key_name" correctly

OR
// If you are looking for equal value then no need to add =
Model::where('column_1','value_1')->where('column_2','value_2')->get();
OR
Model::where(['column_1' => 'value_1','column_2' => 'value_2'])->get();
For Font Awesome 5 SVG version, use

Serial Data Speed:
Data rate (bps) = 1/Tb Tb is the time duration of 1 bit If the bit duration is 2ms then data rate is 1/2x10-3 , which is about 500 bps.
Baud rate:
Baud rate is defined as no. of signalling elements(symbols) in a given unit of time (say 1 sec) or it means number of time signal changes its state.When the signal is binary then baud rate and bit rate are same.
Bit rate:- Bit rate is nothing but number of bits transmitted per second.For example if Bit rate is 1000 bps then 1000 bits are i.e. 0s or 1s transmitted per second.
There are few other terms similar to this (i.e serial speed, bit rate, baud rate, USB transfer rate),and i guess(?) the values that are printed on serial monitor relates to serial speed, baud rate and USB transfer rate. Bit rate isn't an another term, please correct me if i am wrong, because serial monitor prints some values at an interval of time and value is definitely a set of bits. so if one value is printed i can say no of bits present in the respective value which gets printed on serial monitor per unit time will be the bit rate.

Go to your Command prompt/terminal and change path to project directory. Generate key for your application. This is unique for every application so don't make copy paste.
Just run the following command. Key will automatically save to your .env file
php artisan key:generate
Try this
SELECT DATEADD(MINUTE,HOW_MANY_MINUTES,TO_WHICH_TIME)
Here MINUTE
is constant which indicates er are going to add/subtract minutes from TO_WHICH_TIME
specifier. HOW_MANY_MINUTES
is the interval by which we need to add minutes, if it is specified negative, time will be subtracted, else would be added to the TO_WHICH_TIME
specifier and TO_WHICH_TIME
is the original time to which you are adding MINUTE
.
Hope this helps.
As per the PHP manual - parse_url should not be used to validate a URL.
Unfortunately, it seems that filter_var('example.com', FILTER_VALIDATE_URL)
does not perform any better.
Both parse_url()
and filter_var()
will pass malformed URLs such as http://...
Therefore in this case - regex is the better method.
Try this, works!
Excel.Worksheet sheet = xlWorkSheet;
Excel.Series series1 = seriesCollection.NewSeries();
Excel.Range rng = (Excel.Range)xlWorkSheet.Range[xlWorkSheet.Cells[3, 13], xlWorkSheet.Cells[pp, 13]].Cells;
series1.Values = rng;
it's simple, set canvas width and height to screen.width and screen.height. then press F11! think F11 should make full screen in most browsers does in FFox and IE.
I ran into this myself. My recommendation: If you have ownership of the datasource, don't use a List. Use a BindingList. The BindingList has events that fire when items are added or changed, and the DataGridView will automatically update itself when these events are fired.
You can do this using del
and the /S
flag (to tell it to recurse all files from all subdirectories):
del /S C:\Path\to\directory\*
The RD command can also be used. Recursively delete quietly without a prompt:
@RD /S /Q %VAR_PATH%
To find count of unique elements of list use the combination of len()
and set()
.
>>> ls = [1, 2, 3, 4, 1, 1, 2]
>>> len(ls)
7
>>> len(set(ls))
4
