This is for latest iOS Versions(Modified with Xcode 9.3, Swift 4.1). Below are all the stages which makes the lifecycle of a UIViewController
complete.
loadView()
loadViewIfNeeded()
viewDidLoad()
viewWillAppear(_ animated: Bool)
viewWillLayoutSubviews()
viewDidLayoutSubviews()
viewDidAppear(_ animated: Bool)
viewWillDisappear(_ animated: Bool)
viewDidDisappear(_ animated: Bool)
Let me explain all those stages.
1. loadView
This event creates/loads the view that the controller manages. It can load from an associated nib file or an empty UIView
if null was found.
This makes it a good place to create your views in code programmatically.
This is where subclasses should create their custom view hierarchy if they aren't using a nib. Should never be called directly. Only override this method when you programmatically create views and assign the root view to the
view
property Don't call super method when you override loadView
2. loadViewIfNeeded
If incase the view of current viewController
has not been set yet then this method will load the view but remember, this is only available in iOS >=9.0. So if you are supporting iOS <9.0 then don't expect it to come into the picture.
Loads the view controller's view if it has not already been set.
3. viewDidLoad
The viewDidLoad
event is only called when the view is created and loaded into memory but the bounds for the view are not defined yet. This is a good place to initialise the objects that the view controller is going to use.
Called after the view has been loaded. For view controllers created in code, this is after -loadView. For view controllers unarchived from a nib, this is after the view is set.
4. viewWillAppear
This event notifies the viewController
whenever the view appears on the screen. In this step the view has bounds that are defined but the orientation is not set.
Called when the view is about to made visible. Default does nothing.
5. viewWillLayoutSubviews
This is the first step in the lifecycle where the bounds are finalised. If you are not using constraints or Auto Layout you probably want to update the subviews here. This is only available in iOS >=5.0. So if you are supporting iOS <5.0 then don't expect it to come into the picture.
Called just before the view controller's view's layoutSubviews method is invoked. Subclasses can implement as necessary. The default is a nop.
6. viewDidLayoutSubviews
This event notifies the view controller that the subviews have been setup. It is a good place to make any changes to the subviews after they have been set. This is only available in iOS >=5.0. So if you are supporting iOS <5.0 then don't expect it to come into the picture.
Called just after the view controller's view's layoutSubviews method is invoked. Subclasses can implement as necessary. The default is a nop.
7. viewDidAppear
The viewDidAppear
event fires after the view is presented on the screen. Which makes it a good place to get data from a backend service or database.
Called when the view has been fully transitioned onto the screen. Default does nothing
8. viewWillDisappear
The viewWillDisappear
event fires when the view of presented viewController
is about to disappear, dismiss, cover or hide behind other viewController
. This is a good place where you can restrict your network calls, invalidate timer or release objects which is bound to that viewController
.
Called when the view is dismissed, covered or otherwise hidden.
9. viewDidDisappear
This is the last step of the lifecycle that anyone can address as this event fires just after the view of presented viewController
has been disappeared, dismissed, covered or hidden.
Called after the view was dismissed, covered or otherwise hidden. Default does nothing
Now as per Apple when you are implementing this methods you should remember to call super
implementation of that specific method.
If you subclass UIViewController, you must call the super implementation of this method, even if you aren't using a NIB. (As a convenience, the default init method will do this for you, and specify nil for both of this methods arguments.) In the specified NIB, the File's Owner proxy should have its class set to your view controller subclass, with the view outlet connected to the main view. If you invoke this method with a nil nib name, then this class'
-loadView
method will attempt to load a NIB whose name is the same as your view controller's class. If no such NIB in fact exists then you must either call-setView:
before-view
is invoked, or override the-loadView
method to set up your views programatically.
Hope this helped. Thanks.
UPDATE - As @ThomasW pointed inside comment viewWillLayoutSubviews
and viewDidLayoutSubviews
will also be called at other times when subviews of the main view are loaded, for example when cells of a table view or collection view are loaded.
UPDATE - As @Maria pointed inside comment, description of loadView
was updated
Response headers are generally set on the server. Set 'Access-Control-Allow-Headers'
to 'Content-Type'
on server side
Here's a piece of code I put in my scripts that I wan't to run in py2/3-agnostic environment:
# Thank you, python2-3 team, for making such a fantastic mess with
# input/raw_input :-)
real_raw_input = vars(__builtins__).get('raw_input',input)
Now you can use real_raw_input. It's quite expensive but short and readable. Using raw input is usually time expensive (waiting for input), so it's not important.
In theory, you can even assign raw_input instead of real_raw_input but there might be modules that check existence of raw_input and behave accordingly. It's better stay on the safe side.
Code offset dynamic for dynamic page
var pos=$('#send').offset().top;
$('#loading').offset({ top : pos-220});
I was facing the same issue and I tried all the above answers. But unfortunately, none of the above worked.
As a note, I finally solve this by pip uninstall distribute
.
Timestamptz vs Timestamp
The timestamptz field in Postgres is basically just the timestamp field where Postgres actually just stores the “normalised” UTC time, even if the timestamp given in the input string has a timezone.
If your input string is: 2018-08-28T12:30:00+05:30 , when this timestamp is stored in the database, it will be stored as 2018-08-28T07:00:00.
The advantage of this over the simple timestamp field is that your input to the database will be timezone independent, and will not be inaccurate when apps from different timezones insert timestamps, or when you move your database server location to a different timezone.
To quote from the docs:
For timestamp with time zone, the internally stored value is always in UTC (Universal Coordinated Time, traditionally known as Greenwich Mean Time, GMT). An input value that has an explicit time zone specified is converted to UTC using the appropriate offset for that time zone. If no time zone is stated in the input string, then it is assumed to be in the time zone indicated by the system’s TimeZone parameter, and is converted to UTC using the offset for the timezone zone. To give a simple analogy, a timestamptz value represents an instant in time, the same instant for anyone viewing it. But a timestamp value just represents a particular orientation of a clock, which will represent different instances of time based on your timezone.
For pretty much any use case, timestamptz is almost always a better choice. This choice is made easier with the fact that both timestamptz and timestamp take up the same 8 bytes of data.

Best cross browser solution (mostly for IE support) like @Steve said is to make a div 98px in width and height than add a border 1px around it, or you could make a background image for div 100x100 px and draw a border on it.
In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.
But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:
{ Id: 1,
name:'john',
phones:[{title:'home',number:111111,...},
{title:'office',number:22222,...}]
}
sends
{ Id: 1,
name:'john',
phones:[object object]
phones:[object object]
}
For older JVM, in linux...
private static String getPid() throws IOException {
byte[] bo = new byte[256];
InputStream is = new FileInputStream("/proc/self/stat");
is.read(bo);
for (int i = 0; i < bo.length; i++) {
if ((bo[i] < '0') || (bo[i] > '9')) {
return new String(bo, 0, i);
}
}
return "-1";
}
Pointers can be used like any other iterators:
int x[3] = {1, 2, 3};
std::vector<int> v(x, x + 3);
test(v)
use :
socket.Disconnect() //ok
do not use :
socket.disconnect()
I wrote something like this ....
private void frmMain_Load(object sender, EventArgs e)
{
cboFromCurrency.Items.Clear();
cboComboBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
cboComboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
// Load data in comboBox => cboComboBox1.DataSource = .....
// Other things
}
private void cboComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
cboComboBox1.DroppedDown = false;
}
That's all (Y)
Here's an example using underscore functions.
var exampleArray = [{name: 'moe', age: 40}, {name: 'larry', age: 50}, {name: 'curly', age: 60}];
var finalArray = _.compact(_.pluck(exampleArray,"name")).join(",");
Final output would be "moe,larry,curly"
According to @zombat's answer, it's better to validate the Anonymous Functions first:
function exampleMethod($anonFunc) {
//execute anonymous function
if (is_callable($anonFunc)) {
$anonFunc();
}
}
Or validate argument type since PHP 5.4.0:
function exampleMethod(callable $anonFunc) {}
Sometimes the parent ppid cannot be killed, hence kill the zombie pid
kill -9 $(ps -A -ostat,pid | awk '/[zZ]/{ print $2 }')
Assuming you want a run-on of three or more zeros to be removed and your example is one string:
$test_str ="0002030050400000234892839000239074";
$fixed_str = preg_replace('/000+/','',$test_str);
You can make the regex pattern fit what you need if my assumptions are off.
This help?
AFAIK there is no possibility beside from using keys or expect if you are using the command line version ssh
. But there are library bindings for the most programming languages like C, python, php, ... . You could write a program in such a language. This way it would be possible to pass the password automatically. But note this is of course a security problem as the password will be stored in plain text in that program
Use the util namespace, you will be able to register the list as a bean in your application context. You can then reuse the list to inject it in other bean definitions.
private boolean isAppExist() {
PackageManager pm = getPackageManager();
try {
PackageInfo info = pm.getPackageInfo("com.facebook.katana", PackageManager.GET_META_DATA);
} catch (PackageManager.NameNotFoundException e) {
return false;
}
return true;
}
if (isFacebookExist()) {showToast(" Facebook is install.");}
else {showToast(" Facebook is not install.");}
If you got a Apache Maven project, it's easy to use this package in your project. Just specify it in your pom.xml
:

</properties>
<dependencies>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>

pygame
is not distributed via pip
. See this link which provides windows binaries ready for installation.
Finally, use these commands to install pygame wheel with pip
Python 2 (usually called pip)
pip install file.whl
Python 3 (usually called pip3)
pip3 install file.whl
Another tutorial for installing pygame for windows can be found here. Although the instructions are for 64bit windows, it can still be applied to 32bit
I usually do what Josh recommended, but brainstormed and tested a slightly hokey alternative that I felt like sharing.
You can take advantage of the fact that COUNT(ColumnName) doesn't count NULLs, and use something like this:
SELECT COUNT(NULLIF(0, myColumn))
FROM AD_CurrentView
NULLIF - returns NULL if the two passed in values are the same.
Advantage: Expresses your intent to COUNT rows instead of having the SUM() notation. Disadvantage: Not as clear how it is working ("magic" is usually bad).
For TypeScript users:
toggle(event: Event): void {
let elementId: string = (event.target as Element).id;
// do something with the id...
}
enum can reduce many types of "errors" and make the code more manageable
#define STATE_GOOD 0
#define STATE_BAD 1
#define STATE_OTHER 2
int STATE = STATE_OTHER
The definition has no constraints. It's simply just a substitution. It is not able to limit all conditions of the state. When the STATE is assigned to 5, the program will be wrong, because there is no matching state. But the compiler is not going to warn STATE = 5
So it is better to use like this
typedef enum SampleState {
SampleStateGood = 0,
SampleStateBad,
SampleStateOther
} SampleState;
SampleState state = SampleStateGood;
You have two options,
-If you want the value:
Dim MyValue as Variant ' or string/date/long/...
MyValue = ThisWorkbook.Sheets(1).Range("A1").Value
-if you want the cell object:
Dim oCell as Range ' or object (but then you'll miss out on intellisense), and both can also contain more than one cell.
Set oCell = ThisWorkbook.Sheets(1).Range("A1")
Yes. Importing CSS file into another CSS file is possible.
It must be the first rule in the style sheet using the @import rule.
@import "mystyle.css";
@import url("mystyle.css");
The only caveat is that older web browsers will not support it. In fact, this is one of the CSS 'hack' to hide CSS styles from older browsers.
Refer to this list for browser support.
When we write VBA code it is often desired to have the VBA Macro code not visible to end-users. This is to protect your intellectual property and/or stop users messing about with your code. Just be aware that Excel's protection ability is far from what would be considered secure. There are also many VBA Password Recovery [tools] for sale on the www.
To protect your code, open the Excel Workbook and go to Tools>Macro>Visual Basic Editor (Alt+F11). Now, from within the VBE go to Tools>VBAProject Properties and then click the Protection page tab and then check "Lock project from viewing" and then enter your password and again to confirm it. After doing this you must save, close & reopen the Workbook for the protection to take effect.
(Emphasis mine)
Seems like your best bet. It won't stop people determined to steal your code but it's enough to stop casual pirates.
Remember, even if you were able to distribute a compiled copy of your code there'd be nothing to stop people decompiling it.
If you installed pip like this:
- sudo apt install python-pip
- sudo apt install python3-pip
Uninstall them like this:
- sudo apt remove python-pip
- sudo apt remove python3-pip
Not Knowing all of your requirements. For example, are you trying to uniquely identify a computer from all of the computers in the world, or are you just trying to uniquely identify a computer from a set of users of your application. Also, can you create files on the system?
If you are able to create a file. You could create a file and use the creation time of the file as your unique id. If you create it in user space then it would uniquely identify a user of your application on a particular machine. If you created it somewhere global then it could uniquely identify the machine.
Again, as most things, How fast is fast enough.. or in this case, how unique is unique enough.
I wrote a cross-platform library color_ostream for this, with the support of ANSI color, 256 color and true color, all you have to do is directly including it and changing cout to rd_cout like this.
| std | basic color | 256 color | true color |
| :----: | :----: | :----: | :----: |
| std::cout | color_ostream::rd_cout | color_ostream::rd256_cout | color_ostream::rdtrue_cout |
| std::wcout | color_ostream::rd_wcout | color_ostream::rd256_wcout | color_ostream::rdtrue_wcout |
| std::cerr | color_ostream::rd_cerr | color_ostream::rd256_cerr | color_ostream::rdtrue_cerr |
| std::wcerr | color_ostream::rd_wcerr | color_ostream::rd256_wcerr | color_ostream::rdtrue_wcerr |
| std::clog | color_ostream::rd_clog | color_ostream::rd256_clog | color_ostream::rdtrue_clog |
| std::wclog | color_ostream::rd_wclog | color_ostream::rd256_wclog | color_ostream::rdtrue_wclog |
Here is an simple example:
//hello.cpp
#include "color_ostream.h"
using namespace color_ostream;
int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[]) {
rd_wcout.imbue(std::locale(std::locale(),"",LC_CTYPE));
rd_wcout << L"Hello world\n";
rd_wcout << L"Hola Mundo\n";
rd_wcout << L"Bonjour le monde\n";
rd256_wcout << L"\n256 color" << std::endl;
rd256_wcout << L"Hello world\n";
rd256_wcout << L"Hola Mundo\n";
rd256_wcout << L"Bonjour le monde\n";
rdtrue_wcout << L"\ntrue color" << std::endl;
rdtrue_wcout << L"Hello world\n";
rdtrue_wcout << L"Hola Mundo\n";
rdtrue_wcout << L"Bonjour le monde\n";
return 0;
}
As was mentioned in an older version (2009) of the "Tree Conflict" design document:
XFAIL conflict from merge of add over versioned file
This test does a merge which brings a file addition without history onto an existing versioned file.
This should be a tree conflict on the file of the 'local obstruction, incoming add upon merge
' variety. Fixed expectations in r35341.
(This is also called "evil twins" in ClearCase by the way):
a file is created twice (here "added" twice) in two different branches, creating two different histories for two different elements, but with the same name.
The theoretical solution is to manually merge those files (with an external diff tool) in the destination branch 'B2
'.
If you still are working on the source branch, the ideal scenario would be to remove that file from the source branch B1
, merge back from B2
to B1
in order to make that file visible on B1
(you will then work on the same element).
If a merge back is not possible because merges only occurs from B1
to B2
, then a manual merge will be necessary for each B1->B2
merges.
Borrowing from this answer, it seems like the cleanest solution is to use io.TextIOWrapper
. I managed to solve this problem for myself as follows:
from io import TextIOWrapper
...
with open(filename, 'wb') as csvfile, TextIOWrapper(csvfile, encoding='utf-8', newline='') as wrapper:
csvwriter = csv.writer(wrapper)
for data_row in data:
csvwriter.writerow(data_row)
The above answer is not compatible with Python 2. To have compatibility, I suppose one would simply need to wrap all the writing logic in an if
block:
if sys.version_info < (3,):
# Python 2 way of handling CSVs
else:
# The above logic
The font used in menus, dialogs and tool windows can be changed in Settings > Appearance & Behavior > Use custom font.
Take a look at example and do in similar way
(sorce from http://jessenoller.com/2009/02/05/ssh-programming-with-paramiko-completely-different/):
ssh.connect('127.0.0.1', username='jesse',
password='lol')
stdin, stdout, stderr = ssh.exec_command(
"sudo dmesg")
stdin.write('lol\n')
stdin.flush()
data = stdout.read.splitlines()
for line in data:
if line.split(':')[0] == 'AirPort':
print line
I could be misinterpreting your question, but, yes, this is possible. The way that I would go about doing it is this:
var oElement = document.getElementById('elementId'); // get a reference to your element
oElement.onclick = clickHandler; // assign its click function a function reference
function clickHandler() {
// this function will be called whenever the element is clicked
// and can also be called from the context of other functions
}
Now, whenever this element is clicked, the code in clickHandler
will execute. Similarly, you can execute the same code by calling the function from within the context of other functions (or even assign clickHandler
to handle events triggered by other elements)>
A subtle alternative to MaxNoe's answer where you aren't explicitly setting the ticks but instead setting the cadence.
import matplotlib.pyplot as plt
from matplotlib.ticker import (AutoMinorLocator, MultipleLocator)
fig, ax = plt.subplots(figsize=(10, 8))
# Set axis ranges; by default this will put major ticks every 25.
ax.set_xlim(0, 200)
ax.set_ylim(0, 200)
# Change major ticks to show every 20.
ax.xaxis.set_major_locator(MultipleLocator(20))
ax.yaxis.set_major_locator(MultipleLocator(20))
# Change minor ticks to show every 5. (20/4 = 5)
ax.xaxis.set_minor_locator(AutoMinorLocator(4))
ax.yaxis.set_minor_locator(AutoMinorLocator(4))
# Turn grid on for both major and minor ticks and style minor slightly
# differently.
ax.grid(which='major', color='#CCCCCC', linestyle='--')
ax.grid(which='minor', color='#CCCCCC', linestyle=':')
Another option is to use \dfrac instead of \frac, which makes the whole fraction larger and hence more readable.
And no, I don't know if there is an option to get something in between \frac and \dfrac, sorry.
Getting into a non-password protected Java keystore and changing the password can be done with a help of Java programming language itself.
That article contains the code for that:
I found the following simple solution for specifying a user in the HttpContext: https://forums.asp.net/post/5828182.aspx
The getRequestURL()
omits the port when it is 80 while the scheme is http
, or when it is 443 while the scheme is https
.
So, just use getRequestURL()
if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:
StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();
This worked for me.
You need to run it twice once for globals followed by locals
for name in dir():
if not name.startswith('_'):
del globals()[name]
for name in dir():
if not name.startswith('_'):
del locals()[name]
Same problem. The workaround was changing the publish settings from Release to Debug. Re-publish and then change back to Release...
Using ES6 you could do like:
const removeElements = (elms) => elms.forEach(el => el.remove());_x000D_
_x000D_
// Use like:_x000D_
removeElements( document.querySelectorAll(".remove") );
_x000D_
<p class="remove">REMOVE ME</p>_x000D_
<p>KEEP ME</p>_x000D_
<p class="remove">REMOVE ME</p>
_x000D_
As already stated, it's a warning not an error, but (if like me) you want things to run without warnings, you can disable that warning, then re-enable it again when you're done.
SET sql_notes = 0; -- Temporarily disable the "Table already exists" warning
CREATE TABLE IF NOT EXISTS ...
SET sql_notes = 1; -- And then re-enable the warning again
I see a lot of suggestions here, but this collection is missing the following.
button.setOnClickListener(::onButtonClicked)
and in the current class we have a method like this:
private fun onButtonClicked(view: View) {
// do stuff
}
Intelephense 1.3 added undefined type, function, constant, class constant, method, and property diagnostics, where previously in 1.2 there was only undefined variable diagnostics.
Some frameworks are written in a way that provide convenient shortcuts for the user but make it difficult for static analysis engines to discover symbols that are available at runtime.
Stub generators like https://github.com/barryvdh/laravel-ide-helper help fill the gap here and using this with Laravel will take care of many of the false diagnostics by providing concrete definitions of symbols that can be easily discovered.
Still, PHP is a very flexible language and there may be other instances of false undefined symbols depending on how code is written. For this reason, since 1.3.3, intelephense has config options to enable/disable each category of undefined symbol to suit the workspace and coding style.
These options are:
intelephense.diagnostics.undefinedTypes
intelephense.diagnostics.undefinedFunctions
intelephense.diagnostics.undefinedConstants
intelephense.diagnostics.undefinedClassConstants
intelephense.diagnostics.undefinedMethods
intelephense.diagnostics.undefinedProperties
intelephense.diagnostics.undefinedVariables
Setting all of these to false except intelephense.diagnostics.undefinedVariables
will give version 1.2 behaviour. See the VSCode settings UI and search for intelephense
.
Use this html code it will surely help you
<input type="button" value="NEXT" onclick="document.write('<?php //call a function here ex- 'fun();' ?>');" />
one limitation is that it is taking more time to run so wait for few seconds it will work
This is working for me (i use laravel 5.6).

You can simply run sudo service docker start
which will start running your docker server. You can check if you have the docker server by running service --status-all
, you should see docker listed.
If you want to get key from value, its best to use bidimap (bi-directional maps) , you can get key from value in O(1) time.
But, the drawback with this is you can only use unique keyset and valueset.
There is a data structure called Table in java, which is nothing but map of maps like
Table< A, B , C > == map < A , map < B, C > >
Here you can get map<B,C>
by querying T.row(a);
, and you can also get map<A,C>
by querying T.column(b);
In your special case, insert C as some constant.
So, it like < a1, b1, 1 > < a2, b2 , 1 > , ...
So, if you find via T.row(a1) ---> returns map of --> get keyset this returned map.
If you need to find key value then, T.column(b2) --> returns map of --> get keyset of returned map.
Advantages over the previous case :
To avoid having to hardcode an absolute path, you can use the following method that will find and execute your script if it is in your root directory.
public static void runScript() throws IOException, InterruptedException {
ProcessBuilder processBuilder = new ProcessBuilder("./nameOfScript.sh");
//Sets the source and destination for subprocess standard I/O to be the same as those of the current Java process.
processBuilder.inheritIO();
Process process = processBuilder.start();
int exitValue = process.waitFor();
if (exitValue != 0) {
// check for errors
new BufferedInputStream(process.getErrorStream());
throw new RuntimeException("execution of script failed!");
}
}
A robust way to check if an object is an array in javascript is detailed here:
Here are two functions from the xa.js framework which I attach to a utils = {}
‘container’. These should help you properly detect arrays.
var utils = {};
/**
* utils.isArray
*
* Best guess if object is an array.
*/
utils.isArray = function(obj) {
// do an instanceof check first
if (obj instanceof Array) {
return true;
}
// then check for obvious falses
if (typeof obj !== 'object') {
return false;
}
if (utils.type(obj) === 'array') {
return true;
}
return false;
};
/**
* utils.type
*
* Attempt to ascertain actual object type.
*/
utils.type = function(obj) {
if (obj === null || typeof obj === 'undefined') {
return String (obj);
}
return Object.prototype.toString.call(obj)
.replace(/\[object ([a-zA-Z]+)\]/, '$1').toLowerCase();
};
If you then want to check if an object is in an array, I would also include this code:
/**
* Adding hasOwnProperty method if needed.
*/
if (typeof Object.prototype.hasOwnProperty !== 'function') {
Object.prototype.hasOwnProperty = function (prop) {
var type = utils.type(this);
type = type.charAt(0).toUpperCase() + type.substr(1);
return this[prop] !== undefined
&& this[prop] !== window[type].prototype[prop];
};
}
And finally this in_array function:
function in_array (needle, haystack, strict) {
var key;
if (strict) {
for (key in haystack) {
if (!haystack.hasOwnProperty[key]) continue;
if (haystack[key] === needle) {
return true;
}
}
} else {
for (key in haystack) {
if (!haystack.hasOwnProperty[key]) continue;
if (haystack[key] == needle) {
return true;
}
}
}
return false;
}
In my case it was the wrong ownership for /var/lib/php/session
. I changed that to the Apache user and group (the user and group that the webserver runs as) and all was well.

Personally, I found that, since we maintain a ngRoutes
collection (long story) i find the most enjoyment from:
GOTO(ri) {
this.router.navigate(this.ngRoutes[ri]);
}
I actually use it as part of one of our interview questions. This way, I can get a near-instant read at who's been developing forever by watching who twitches when they run into GOTO(1)
for Homepage redirection.
EDIT:
The OP was not looking to use cross-domain requests, but jQuery supports JSONP as of v1.5. See jQuery.ajax(), specificically the crossDomain
parameter.
The regular jQuery Ajax requests will not work cross-site, so if you want to query a remote RESTful web service, you'll probably have to make a proxy on your server and query that with a jQuery get request. See this site for an example.
If it's a SOAP web service, you may want to try the jqSOAPClient plugin.
You will need to do an Ajax call I suspect. Here is an example of an Ajax called made by jQuery to get you started. The Code logs in a user to my system but returns a bool as to whether it was successful or not. Note the ScriptMethod and WebMethod attributes on the code behind method.
in markup:
var $Username = $("#txtUsername").val();
var $Password = $("#txtPassword").val();
//Call the approve method on the code behind
$.ajax({
type: "POST",
url: "Pages/Mobile/Login.aspx/LoginUser",
data: "{'Username':'" + $Username + "', 'Password':'" + $Password + "' }", //Pass the parameter names and values
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
error: function (jqXHR, textStatus, errorThrown) {
alert("Error- Status: " + textStatus + " jqXHR Status: " + jqXHR.status + " jqXHR Response Text:" + jqXHR.responseText) },
success: function (msg) {
if (msg.d == true) {
window.location.href = "Pages/Mobile/Basic/Index.aspx";
}
else {
//show error
alert('login failed');
}
}
});
In Code Behind:
/// <summary>
/// Logs in the user
/// </summary>
/// <param name="Username">The username</param>
/// <param name="Password">The password</param>
/// <returns>true if login successful</returns>
[WebMethod, ScriptMethod]
public static bool LoginUser( string Username, string Password )
{
try
{
StaticStore.CurrentUser = new User( Username, Password );
//check the login details were correct
if ( StaticStore.CurrentUser.IsAuthentiacted )
{
//change the status to logged in
StaticStore.CurrentUser.LoginStatus = Objects.Enums.LoginStatus.LoggedIn;
//Store the user ID in the list of active users
( HttpContext.Current.Application[ SessionKeys.ActiveUsers ] as Dictionary<string, int> )[ HttpContext.Current.Session.SessionID ] = StaticStore.CurrentUser.UserID;
return true;
}
else
{
return false;
}
}
catch ( Exception ex )
{
return false;
}
}
A bit late to the party but still - I prefer using numpy where:

df['First Season'] = np.where(df['First Season'] > 1990, 1, df['First Season'])

Top level await
is not supported. There are a few discussions by the standards committee on why this is, such as this Github issue.
There's also a thinkpiece on Github about why top level await is a bad idea. Specifically he suggests that if you have code like this:
// data.js
const data = await fetch( '/data.json' );
export default data;
Now any file that imports data.js
won't execute until the fetch completes, so all of your module loading is now blocked. This makes it very difficult to reason about app module order, since we're used to top level Javascript executing synchronously and predictably. If this were allowed, knowing when a function gets defined becomes tricky.
My perspective is that it's bad practice for your module to have side effects simply by loading it. That means any consumer of your module will get side effects simply by requiring your module. This badly limits where your module can be used. A top level await
probably means you're reading from some API or calling to some service at load time. Instead you should just export async functions that consumers can use at their own pace.
If you set up your project with the default gradle package structure, i.e.:
src/main/java
src/main/resources
src/test/java
src/test/resources
then you won't need to modify sourceSets to run your tests. Gradle will figure out that your test classes and resources are in src/test. You can then run as Oliver says above. One thing to note: Be careful when setting property files and running your test classes with both gradle and you IDE. I use Eclipse, and when running JUnit from it, Eclipse chooses one classpath (the bin directory) whereas gradle chooses another (the build directory). This can lead to confusion if you edit a resource file, and don't see your change reflected at test runtime.
I know it is too late to answer to this question. But, I thought it would still be nice to share how I sorted this out when I had the same issue. Here is what I did.
DECLARE @Number int = 1;
SELECT RIGHT('0'+ CONVERT(VARCHAR, @Number), 2)
--OR
SELECT RIGHT(CONVERT(VARCHAR, 100 + @Number), 2)
GO
I had success with easy killing all active httpd processes in Monitor Activity tool:
1) close XAMPP control
2) open Monitor Activity
3) select filter for All processes (default is My processes)
4) in fulltext search type: httpd
5) kill all showen items
6) relaunch XAMPP control and launch apache again
And answering this seven years after the question was asked, it is possible to do this comparison using built-in methods:
Month.toInt("January") > Month.toInt("May")
becomes
Array.FindIndex( CultureInfo.CurrentCulture.DateTimeFormat.MonthNames,
t => t.Equals("January", StringComparison.CurrentCultureIgnoreCase)) >
Array.FindIndex( CultureInfo.CurrentCulture.DateTimeFormat.MonthNames,
t => t.Equals("May", StringComparison.CurrentCultureIgnoreCase))
Which can be refactored into an extension method for simplicity. The following is a LINQPad example (hence the Dump()
method calls):
void Main()
{
("January".GetMonthIndex() > "May".GetMonthIndex()).Dump();
("January".GetMonthIndex() == "january".GetMonthIndex()).Dump();
("January".GetMonthIndex() < "May".GetMonthIndex()).Dump();
}
public static class Extension {
public static int GetMonthIndex(this string month) {
return Array.FindIndex( CultureInfo.CurrentCulture.DateTimeFormat.MonthNames,
t => t.Equals(month, StringComparison.CurrentCultureIgnoreCase));
}
}
With output:
False
True
True
I also ran into the same problem with TestNG version 6.14.2
However, this was due to a foolish mistake on my end and there is no issue whatsoever with maven, testng or eclipse. What I was doing was -
The best answer I can find, is in one of the comments here. Adding it to the answer so that someone won't miss the comment and should definitely try this out. It fixed the issue for me.
We need to map the solution folder to a drive using the "subst" command in command prompt- e.g., subst z:
And then open the solution from this drive (z in this case). This would shorten the path as much as possible and could solve the lengthy filename issue.
In C you get an implicit conversion from void *
to any other (data) pointer.
mkdir [-switch] foldername
-p
is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.
From the man page:
-p, --parents no error if existing, make parent directories as needed
Example:
mkdir -p storage/framework/{sessions,views,cache}
This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.

PUT ing
PUT /binders/{id}/docs
Create or update, and relate a single document to a binder
e.g.:

PATCH ing
PATCH /docs
Create docs if they do not exist and relate them to binders
e.g.:
PATCH /docs HTTP/1.1
[

I'll include additional insights later, but in the meantime if you want to, have a look at RFC 5789, RFC 6902 and William Durand's Please. Don't Patch Like an Idiot blog entry.

A minor update to this: a sender should never set the Return-Path:
header. There's no such thing as a Return-Path:
header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From
unless the local system needs some kind of quirky routing.
It's a common misunderstanding because users rarely see an email without a Return-Path:
header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path:
header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4
If you are using Sql Server (any edition, even express) then you can install Sql Server Reporting Services. This allows the creation of reports through a visual studio plugin, or through a browser control and can export the reports in a variety of formats, including PDF. You can view the reports through the winforms report viewer control which is included, or take advantage of all of the built in generated web content.
The learning curve is not very steep at all if you are used to using datasets in Visual Studio.
You can use:
EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal

There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.
Spring doc "Registering the handler and the schema" shows how it should be done.
In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.
From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.
As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:
http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd
This means that (in xsi:schemaLocation)
http://www.springframework.org/schema/context/spring-context-2.5.xsd
will be validated against
org/springframework/context/config/spring-context-2.5.xsd
in the classpath.
http://www.springframework.org/schema/context/spring-context-3.0.xsd
or
http://www.springframework.org/schema/context/spring-context.xsd
will be validated against
org/springframework/context/config/spring-context-3.0.xsd
in the classpath.
http://www.springframework.org/schema/context/spring-context-2.1.xsd
is not defined so Spring will look for it using the literal URL defined in schemaLocation.
First of all, anyone can create 2 keys. One to encrypt data, and another to decrypt data. The former can be a private key, and the latter a public key, AND VICERZA.
Second of all, in simplest terms, a Certificate Authority (CA) offers the service of creating a certificate for you. How? They use certain values (the CA's issuer name, your server's public key, company name, domain, etc.) and they use their SUPER DUPER ULTRA SECURE SECRET private key and encrypt this data. The result of this encrypted data is a SIGNATURE.
So now the CA gives you back a certificate. The certificate is basically a file containing the values previously mentioned (CA's issuer name, company name, domain, your server's public key, etc.), INCLUDING the signature (i.e. an encrypted version of the latter values).
Now, with all that being said, here is a REALLY IMPORTANT part to remember: your device/OS (Windows, Android, etc.) pretty much keeps a list of all major/trusted CA's and their PUBLIC KEYS (if you're thinking that these public keys are used to decrypt the signatures inside the certificates, YOU ARE CORRECT!).
Ok, if you read the above, this sequential example will be a breeze now:
Why? Think about it, only this public key can decrypt the signature in such a way that the contents look like they did before the private key encrypted them.
This is one of the main reasons (if not the main reason) why the above standard was created.
Let's say hacker-Jane intercepts internet-user-Bob's request, and replies with her own certificate. However, hacker-Jane is still careful enough to state in the certificate that the issuer was Example-CA. Lastly, hacker-Jane remembers that she has to include a signature on the certificate. But what key does Jane use to sign (i.e. create an encrypted value of the certificate main contents) the certificate?????
So even if hacker-Jane signed the certificate with her own key, you see what's gonna happen next. The browser is gonna say: "ok, this certificate is issued by Example-CA, let's decrypt the signature with Example-CA's public key". After decryption, the browser notices that the certificate contents don't match at all. Hence, the browser gives a very clear warning to the user, and it says it doesn't trust the connection.
I found that I was using a selector for my rendorTo div that I was using to render my column highcharts graph. Apparently it adds the selector for you so you just need to pass id.
renderTo: $('#myGraphDiv') to a string 'myGraphDiv' this fixed the error hope this helps someone else out as well.
You need to use Arrow function ()=>

LCASE or UCASE respectively.
Example:
SELECT UCASE(MyColumn) AS Upper, LCASE(MyColumn) AS Lower
FROM MyTable
I had the same problem and resolved it by changing the character set of the column. Even though your database has a default character set of utf-8
I think it's possible for database columns to have a different character set in MySQL. Here's the SQL QUERY I used:

A bit late but this is what I'm doing with journald
. It's pretty powerful.
You need to be running your docker containers on an OS with systemd-journald
.
docker run -d --log-driver=journald myapp
This pipes the whole lot into host's journald which takes care of stuff like log pruning, storage format etc and gives you some cool options for viewing them:
journalctl CONTAINER_NAME=myapp -f
which will feed it to your console as it is logged,
journalctl CONTAINER_NAME=myapp > output.log
which gives you the whole lot in a file to take away, or
journalctl CONTAINER_NAME=myapp --since=17:45
Plus you can still see the logs via docker logs ....
if that's your preference.
No more > my.log
or -v "/apps/myapp/logs:/logs"
etc
Have you tried QCoreApplication::applicationDirPath()
qDebug() << "App path : " << qApp->applicationDirPath();
It may be obvious but, by stating the Range and not including which workbook or worksheet then it may be trying to CountA() on a different sheet entirely. I find to fully address these things saves a lot of headaches.
For only validating syntax:
shellcheck [programPath]
For running the program only if syntax passes, so debugging both syntax and execution:
shellproof [programPath]
Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).
javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456
Then load the properties to your environment from your code. This makes your application configurable.
FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);
You can use the WooCommerce Layered Nav widget, which allows you to use different sets of attributes as filters for products. Here's the "official" description:
Shows a custom attribute in a widget which lets you narrow down the list of products when viewing product categories.
If you look into plugins/woocommerce/widgets/widget-layered_nav.php, you can see the way it operates with the attributes in order to set filters. The URL then looks like this:
... and the digits are actually the id-s of the different attribute values, that you want to set.
It depends what you mean by "it". The iterator knows what index it's reached, yes - in the case of a List<T>
or an array. But there's no general index within IEnumerator<T>
. Whether it's iterating over an indexed collection or not is up to the implementation. Plenty of collections don't support direct indexing.
(In fact, foreach
doesn't always use an iterator at all. If the compile-time type of the collection is an array, the compiler will iterate over it using array[0]
, array[1]
etc. Likewise the collection can have a method called GetEnumerator()
which returns a type with the appropriate members, but without any implementation of IEnumerable
/IEnumerator
in sight.)
Options for maintaining an index:
for
loopUse a projection which projects each item to an index/value pair, e.g.
foreach (var x in list.Select((value, index) => new { value, index }))
{
// Use x.value and x.index in here
}
Use my SmartEnumerable
class which is a little bit like the previous option
All but the first of these options will work whether or not the collection is naturally indexed.
Once I realized I was running an Oracle database, not MySQL, I found the answer
select * from v$database;
or
select ora_database_name from dual;
Try both. Credit and source goes to: http://www.perlmonks.org/?node_id=520376.

In the year 2010 I would have joined the author of this questions and would have strongly voted for JOIN
, but with much more experience (especially in MySQL) I can state: Yes subqueries can be better. I've read multiple answers here; some stated subqueries are faster, but it lacked a good explanation. I hope I can provide one with this (very) late answer:
First of all, let me say the most important: There are different forms of sub-queries
And the second important statement: Size matters
If you use sub-queries, you should be aware of how the DB-Server executes the sub-query. Especially if the sub-query is evaluated once or for every row! On the other side, a modern DB-Server is able to optimize a lot. In some cases a subquery helps optimizing a query, but a newer version of the DB-Server might make the optimization obsolete.
SELECT moo, (SELECT roger FROM wilco WHERE moo = me) AS bar FROM foo
Be aware that a sub-query is executed for every resulting row from foo
.
Avoid this if possible; it may drastically slow down your query on huge datasets. However, if the sub-query has no reference to foo
it can be optimized by the DB-server as static content and could be evaluated only once.
SELECT moo FROM foo WHERE bar = (SELECT roger FROM wilco WHERE moo = me)
If you are lucky, the DB optimizes this internally into a JOIN
. If not, your query will become very, very slow on huge datasets because it will execute the sub-query for every row in foo
, not just the results like in the select-type.
SELECT moo, bar
FROM foo
LEFT JOIN (
SELECT MIN(bar), me FROM wilco GROUP BY me
) ON moo = me
This is interesting. We combine JOIN
with a sub-query. And here we get the real strength of sub-queries. Imagine a dataset with millions of rows in wilco
but only a few distinct me
. Instead of joining against a huge table, we have now a smaller temporary table to join against. This can result in much faster queries depending on database size. You can have the same effect with CREATE TEMPORARY TABLE ...
and INSERT INTO ... SELECT ...
, which might provide better readability on very complex queries (but can lock datasets in a repeatable read isolation level).
SELECT moo, bar
FROM (
SELECT moo, CONCAT(roger, wilco) AS bar
FROM foo
GROUP BY moo
HAVING bar LIKE 'SpaceQ%'
) AS temp_foo
ORDER BY bar
You can nest sub-queries in multiple levels. This can help on huge datasets if you have to group or sort the results. Usually the DB-Server creates a temporary table for this, but sometimes you do not need sorting on the whole table, only on the resultset. This might provide much better performance depending on the size of the table.
Sub-queries are no replacement for a JOIN
and you should not use them like this (although possible). In my humble opinion, the correct use of a sub-query is the use as a quick replacement of CREATE TEMPORARY TABLE ...
. A good sub-query reduces a dataset in a way you cannot accomplish in an ON
statement of a JOIN
. If a sub-query has one of the keywords GROUP BY
or DISTINCT
and is preferably not situated in the select fields or the where statement, then it might improve performance a lot.
When it shows the red writing - the error , don't close the emulator - leave it as is and run the application again.
With Java 8, interfaces can have static methods. They can also have concrete instance methods, but not instance fields.
There are really two questions here:
There was no strong technical reason why interfaces couldn't have had static methods in previous versions. This is summed up nicely by the poster of a duplicate question. Static interface methods were initially considered as a small language change, and then there was an official proposal to add them in Java 7, but it was later dropped due to unforeseen complications.
Finally, Java 8 introduced static interface methods, as well as override-able instance methods with a default implementation. They still can't have instance fields though. These features are part of the lambda expression support, and you can read more about them in Part H of JSR 335.
The answer to the second question is a little more complicated.
Static methods are resolvable at compile time. Dynamic dispatch makes sense for instance methods, where the compiler can't determine the concrete type of the object, and, thus, can't resolve the method to invoke. But invoking a static method requires a class, and since that class is known statically—at compile time—dynamic dispatch is unnecessary.
A little background on how instance methods work is necessary to understand what's going on here. I'm sure the actual implementation is quite different, but let me explain my notion of method dispatch, which models observed behavior accurately.
Pretend that each class has a hash table that maps method signatures (name and parameter types) to an actual chunk of code to implement the method. When the virtual machine attempts to invoke a method on an instance, it queries the object for its class and looks up the requested signature in the class's table. If a method body is found, it is invoked. Otherwise, the parent class of the class is obtained, and the lookup is repeated there. This proceeds until the method is found, or there are no more parent classes—which results in a NoSuchMethodError
.
If a superclass and a subclass both have an entry in their tables for the same method signature, the sub class's version is encountered first, and the superclass's version is never used—this is an "override".
Now, suppose we skip the object instance and just start with a subclass. The resolution could proceed as above, giving you a sort of "overridable" static method. The resolution can all happen at compile-time, however, since the compiler is starting from a known class, rather than waiting until runtime to query an object of an unspecified type for its class. There is no point in "overriding" a static method since one can always specify the class that contains the desired version.
Here's a little more material to address the recent edit to the question.
It sounds like you want to effectively mandate a constructor-like method for each implementation of IXMLizable
. Forget about trying to enforce this with an interface for a minute, and pretend that you have some classes that meet this requirement. How would you use it?
class Foo implements IXMLizable<Foo> {
public static Foo newInstanceFromXML(Element e) { ... }
}
Foo obj = Foo.newInstanceFromXML(e);
Since you have to explicitly name the concrete type Foo
when "constructing" the new object, the compiler can verify that it does indeed have the necessary factory method. And if it doesn't, so what? If I can implement an IXMLizable
that lacks the "constructor", and I create an instance and pass it to your code, it is an IXMLizable
with all the necessary interface.
Construction is part of the implementation, not the interface. Any code that works successfully with the interface doesn't care about the constructor. Any code that cares about the constructor needs to know the concrete type anyway, and the interface can be ignored.
An old thread, but...Answer of Konerak works, but why would you even set size of a container by default. What I prefer is to use code wherever no matter of hog big page size is. So this my code:
<style>
#container {
position: relative;
height: 100%;
}
#footer {
position: absolute;
bottom: 0;
}
</style>
</HEAD>
<BODY>
<div id="container">
<h1>Some heading</h1>
<p>Some text you have</p>
<br>
<br>
<div id="footer"><p>Rights reserved</p></div>
</div>
</BODY>
</HTML>
The trick is in <br>
where you break new line. So, when page is small you'll see footer at bottom of page, as you want.
BUT, when a page is big SO THAT YOU MUST SCROLL IT DOWN, then your footer is going to be 2 new lines under the whole content above. And If you will then make page bigger, your footer is allways going to go DOWN. I hope somebody will find this useful.
@datenstation had the correct concept. Here is a working example that uses CTE to cache variable's names:
CREATE VIEW vwImportant_Users AS
WITH params AS (
SELECT
varType='%Admin%',
varMinStatus=1)
SELECT status, name
FROM sys.sysusers, params
WHERE status > varMinStatus OR name LIKE varType
SELECT * FROM vwImportant_Users
also via JOIN
WITH params AS ( SELECT varType='%Admin%', varMinStatus=1)
SELECT status, name
FROM sys.sysusers INNER JOIN params ON 1=1
WHERE status > varMinStatus OR name LIKE varType
also via CROSS APPLY
WITH params AS ( SELECT varType='%Admin%', varMinStatus=1)
SELECT status, name
FROM sys.sysusers CROSS APPLY params
WHERE status > varMinStatus OR name LIKE varType
If you're using SQL Server 2005, you could use the FOR XML PATH command.
SELECT [VehicleID]
, [Name]
, (STUFF((SELECT CAST(', ' + [City] AS VARCHAR(MAX))
FROM [Location]
WHERE (VehicleID = Vehicle.VehicleID)
FOR XML PATH ('')), 1, 2, '')) AS Locations
FROM [Vehicle]
It's a lot easier than using a cursor, and seems to work fairly well.
The most correct way is to use HttpContext.Current.Server.MapPath("~/App_Data");
. This means you can only retrieve the path from a method where the HttpContext
is available. It makes sense: the App_Data directory is a web project folder structure [1].
If you need the path to ~/App_Data from a class where you don't have access to the HttpContext
you can always inject a provider interface using your IoC container:
public interface IAppDataPathProvider
{
string GetAppDataPath();
}
Implement it using your HttpApplication
:
public class AppDataPathProvider : IAppDataPathProvider
{
public string GetAppDataPath()
{
return MyHttpApplication.GetAppDataPath();
}
}
Where MyHttpApplication.GetAppDataPath
looks like:
public class MyHttpApplication : HttpApplication
{
// of course you can fetch&store the value at Application_Start
public static string GetAppDataPath()
{
return HttpContext.Current.Server.MapPath("~/App_Data");
}
}

302 is a response indicating change of resource location - "Found".
The url where the resource should be now located should be in the response 'Location' header.
The "jump" should be done by the requesting client (make a new request to the resource url in the response Location header field).

You can initialize a Dictionary
(and other collections) inline. Each member is contained with braces:
Dictionary<int, StudentName> students = new Dictionary<int, StudentName>
{
{ 111, new StudentName { FirstName = "Sachin", LastName = "Karnik", ID = 211 } },
{ 112, new StudentName { FirstName = "Dina", LastName = "Salimzianova", ID = 317 } },
{ 113, new StudentName { FirstName = "Andy", LastName = "Ruth", ID = 198 } }
};
See Microsoft Docs for details.
You can add header "Content-Type: text/html; charset=UTF-8" to your message body.
$headers = "Content-Type: text/html; charset=UTF-8";
If you use native mail()
function $headers array will be the 4th parameter
mail($to, $subject, $message, $headers)
If you user PEAR Mail::factory() code will be:
$smtp = Mail::factory('smtp', $params);
$mail = $smtp->send($to, $headers, $body);
I changed the memory limit from .htaccess and this problem got resolved.
I was trying to scan my website from one of the antivirus plugin and there I was getting this problem. I increased memory by pasting this in my .htaccess file in Wordpress folder:

After scan was over, I removed this line to make the size as it was before.
To UPLOAD a single file, you will need to create a bash script. Something like the following should work on OS X if you have sshpass
installed.

sftpx <password> <user@hostname> <localfile> <remotefile>
Put this script somewhere in your path and call it sftpx
:
#!/bin/bash

export TMPDIR=/tmp/$RND
export FILENAME=$(basename "$4")
export DSTDIR=$(dirname "$4")
mkdir $TMPDIR
cp "$3" $TMPDIR/$FILENAME
export SSHPASS=$1
sshpass -e sftp -oBatchMode=no -b - $2 << !
lcd $TMPDIR
cd $DSTDIR
put $FILENAME
bye
!
rm $TMPDIR/$FILENAME
rmdir $TMPDIR
Actually, in Python 3 the module imp
is marked as DEPRECATED. Well, at least that's true for 3.4.
Instead the reload
function from the importlib
module should be used:
https://docs.python.org/3/library/importlib.html#importlib.reload
But be aware that this library had some API-changes with the last two minor versions.
Here is a more general answer for future viewers of this question. The layout we will make is below:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dynamic_linearlayout);
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll_example);
// Add textview 1
TextView textView1 = new TextView(this);
textView1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
textView1.setText("programmatically created TextView1");
textView1.setBackgroundColor(0xff66ff66); // hex color 0xAARRGGBB
textView1.setPadding(20, 20, 20, 20);// in pixels (left, top, right, bottom)
linearLayout.addView(textView1);
// Add textview 2
TextView textView2 = new TextView(this);
LayoutParams layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
layoutParams.gravity = Gravity.RIGHT;
layoutParams.setMargins(10, 10, 10, 10); // (left, top, right, bottom)
textView2.setLayoutParams(layoutParams);
textView2.setText("programmatically created TextView2");
textView2.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
textView2.setBackgroundColor(0xffffdbdb); // hex color 0xAARRGGBB
linearLayout.addView(textView2);
}
Note that for LayoutParams
you must specify the kind of layout for the import, as in
import android.widget.LinearLayout.LayoutParams;
Otherwise you need to use LinearLayout.LayoutParams
in the code.
Here is the xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ll_example"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ff99ccff"
android:orientation="vertical" >
</LinearLayout>
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// NOTE: setContentView is below, not here
// Create new LinearLayout
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setBackgroundColor(0xff99ccff);
// Add textviews
TextView textView1 = new TextView(this);
textView1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
textView1.setText("programmatically created TextView1");
textView1.setBackgroundColor(0xff66ff66); // hex color 0xAARRGGBB
textView1.setPadding(20, 20, 20, 20); // in pixels (left, top, right, bottom)
linearLayout.addView(textView1);
TextView textView2 = new TextView(this);
LayoutParams layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
layoutParams.gravity = Gravity.RIGHT;
layoutParams.setMargins(10, 10, 10, 10); // (left, top, right, bottom)
textView2.setLayoutParams(layoutParams);
textView2.setText("programmatically created TextView2");
textView2.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
textView2.setBackgroundColor(0xffffdbdb); // hex color 0xAARRGGBB
linearLayout.addView(textView2);
// Set context view
setContentView(linearLayout);
}
@Override

Well... I would like you to understand more specific areas of space. \t
is actually assorted as a horizontal space, not a vertical space. (test out inserting \t
in Notepad)
If you use Java, simply use \v
. See the reference below.
\h
- A horizontal whitespace character:
[\t\xA0\u1680\u180e\u2000-\u200a\u202f\u205f\u3000]
\v
- A vertical whitespace character:
[\n\x0B\f\r\x85\u2028\u2029]
But I am aware that you use .NET. So my answer to replacing every vertical space is..
string replacement = Regex.Replace(s, @"[\n\u000B\u000C\r\u0085\u2028\u2029]", "");
I faced the same issue, after reference somewhere, it worked as below changing:

You can use setenv.bat or .sh to pass the environment variables to the Tomcat.
Create CATALINA_BASE/bin/setenv.bat or .sh file and put the following line in it, and then start the Tomcat.
On Windows:
set APP_MASTER_PASSWORD=foo
On Unix like systems:
export APP_MASTER_PASSWORD=foo
Plain HTML does not support this. You'll need to use some JavaScript code.
Also, note that large parts of the world are using a popup blocker nowadays. You may want to reconsider your design!
You can use the in place option -i
of sed
for Linux and Unix:
sed -i 's/[ \t]*$//' "$1"
Be aware the expression will delete trailing t
's on OSX (you can use gsed
to avoid this problem). It may delete them on BSD too.
If you don't have gsed, here is the correct (but hard-to-read) sed syntax on OSX:
sed -i '' -E 's/[ '$'\t'']+$//' "$1"
Three single-quoted strings ultimately become concatenated into a single argument/expression. There is no concatenation operator in bash, you just place strings one after the other with no space in between.
The $'\t'
resolves as a literal tab-character in bash (using ANSI-C quoting), so the tab is correctly concatenated into the expression.
Here's why: As it is says in the Javadoc:
The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.
This check is done in the next()
method of the iterator (as you can see by the stacktrace). But we will reach the next()
method only if hasNext()
delivered true, which is what is called by the for each to check if the boundary is met. In your remove method, when hasNext()
checks if it needs to return another element, it will see that it returned two elements, and now after one element was removed the list only contains two elements. So all is peachy and we are done with iterating. The check for concurrent modifications does not occur, as this is done in the next()
method which is never called.
Next we get to the second loop. After we remove the second number the hasNext method will check again if can return more values. It has returned two values already, but the list now only contains one. But the code here is:
public boolean hasNext() {
return cursor != size();
}
1 != 2, so we continue to the next()
method, which now realizes that someone has been messing with the list and fires the exception.
Hope that clears your question up.
List.remove()
will not throw ConcurrentModificationException
when it removes the second last element from the list.
If you're at the top level - or able to cleanly get to the top level - of the thread, then just returning is nice. Throwing an exception isn't as clean, as you need to be able to check that nothing's going to catch the exception and ignore it.
The reason you need to use Thread.currentThread()
in order to call interrupt()
is that interrupt()
is an instance method - you need to call it on the thread you want to interrupt, which in your case happens to be the current thread. Note that the interruption will only be noticed the next time the thread would block (e.g. for IO or for a monitor) anyway - it doesn't mean the exception is thrown immediately.
If you have installed docker on Windows 10 Pro with Hyper-V enabled and you are still not able to run Docker on Windows 10, then, as the error suggests, your docker daemon is not started.
The following steps helped me to start docker successfully:
Use command on cmd(Admin mode)
docker-machine restart default
Then you'll get a message something like:
open
C:\User\\{User_name}\\.docker\machine\machines\default\config.json
:
The system cannot find the file specified.
Go to the docker icon which will be on your windows tray (bottom right corner of the desktop)
Right click on the docker icon > Settings > Reset > Restart Docker
It will take few moments
Then you'll see the following message:
Docker is running with the green indicator
Note: If you already had Docker containers running on your system, then don't follow these steps. You may lose the existing containers.
You may also want to consider the possibility of using SWT (another Java GUI library). Pros and cons of each are listed at:
In your button1_click function you are using '==' for button2.Enabled == true;
This should be button2.Enabled = true;
You can just go for String
replace method.-
line1 = line1.replace("\"", "");
You are having a very common closure problem in the for in
loop:
Variables enclosed in a closure share the same single environment, so by the time the click
callback from the addListener
is called, the loop will have run its course and the info
variable will be left pointing to the last object, which happens to be the last InfoWindow
created.
In this case, one easy way to solve this problem would be to augment your Marker
object with the InfoWindow
:
var marker = new google.maps.Marker({map: map, position: point, clickable: true});
marker.info = new google.maps.InfoWindow({
content: '<b>Speed:</b> ' + values.inst + ' knots'
});
google.maps.event.addListener(marker, 'click', function() {
marker.info.open(map, marker);
});
This can be quite a tricky topic, if you are not familiar with how closures work. You may to check out the following Mozilla article for a brief introduction:
Also keep in mind, that the v3 API allows multiple InfoWindow
s on the map. If you intend to have just one InfoWindow
visible at the time, you should instead use a single InfoWindow
object, and then open it and change its content whenever the marker is clicked (Source).
So you want to split on spaces, and on commas and periods that aren't surrounded by numbers. This should work:
r" |(?<![0-9])[.,](?![0-9])"
The simplest way to extract data from a DataTable
when you have multiple data types (not just strings) is to use the Field<T>
extension method available in the System.Data.DataSetExtensions
assembly.
var id = row.Field<int>("ID"); // extract and parse int
var name = row.Field<string>("Name"); // extract string
From MSDN, the Field<T>
method:
Provides strongly-typed access to each of the column values in the DataRow.
This means that when you specify the type it will validate and unbox the object.
For example:
// iterate over the rows of the datatable
foreach (var row in table.AsEnumerable()) // AsEnumerable() returns IEnumerable<DataRow>
{
var id = row.Field<int>("ID"); // int
var name = row.Field<string>("Name"); // string
var orderValue = row.Field<decimal>("OrderValue"); // decimal
var interestRate = row.Field<double>("InterestRate"); // double
var isActive = row.Field<bool>("Active"); // bool
var orderDate = row.Field<DateTime>("OrderDate"); // DateTime
}
It also supports nullable types:
DateTime? date = row.Field<DateTime?>("DateColumn");
This can simplify extracting data from DataTable
as it removes the need to explicitly convert or parse the object into the correct types.
Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/
The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.
Setting Up a Custom SSH Server
The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.
You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.
How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.
Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.
To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.
Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.
Example 10-1. sshserver.py

The problem was that the ID column wasn't getting any value. I saw on @Martin Smith SQL Fiddle that he declared the ID column with DEFAULT newid
and I didn't..

Try this. Fix permissions on files:
cd /opt/Popcorn (or wherever it is)
chmod -R 555 * (755 if not ok)
chown -R root:root *
“sudo su” to get permissions on your filesystem.
Swift 4 with saving array types
extension Array {
func take(_ elementsCount: Int) -> [Element] {
let min = Swift.min(elementsCount, count)
return Array(self[0..<min])
}
}
If you want just a single field, you could use fetchColumn instead of fetch - http://www.php.net/manual/en/pdostatement.fetchcolumn.php
I would recommend replace()
rather than attach()
/detach()
in your tab handling.
Or, switch to ViewPager
. Here is a sample project showing a ViewPager
, with tabs, hosting 10 maps.
The second is almost correct:
{
"foos" : [{
"prop1":"value1",
"prop2":"value2"
}, {
"prop1":"value3",
"prop2":"value4"
}]
}
Downloading Wget is not necessary; the .NET Framework has web client classes built in.
$wc = New-Object system.Net.WebClient;
$sms = Read-Host "Enter SMS text";
$sms = [System.Web.HttpUtility]::UrlEncode($sms);
$smsResult = $wc.downloadString("http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$sms&encoding=windows-1255")
I had the same error, when I copied a project to another computer.
I then checked all properties of the project on both machines, and the only thing that was different was the order of items in Java Build Path - tab Order and Export.
I moved the items Android X.X.X and Android Dependencies above the other 2 in the list (in my case, src and gen folders) and voila, it worked again!
I'm not really sure if the different order was actually the problem, but at least changing it (and saving the properties again) seemed to help...
You need to alias the subquery. Thus, your statement should be:
Select Z.id
From (
Select id, time
From dbo.tablea
Union All
Select id, time
From dbo.tableb
) As Z
Group By Z.id

So basically you want to convert a String into an Integer right! here is what I mostly use and that is also mentioned in official documentation..
fn main() {
let char = "23";
let char : i32 = char.trim().parse().unwrap();
println!("{}", char + 1);
}
This works for both String and &str Hope this will help too.
In Express 4.x, there is an attachment()
method to Response
:
res.attachment();
// Content-Disposition: attachment
res.attachment('path/to/logo.png');
// Content-Disposition: attachment; filename="logo.png"
// Content-Type: image/png
EDITED: The best solution is using NavigationEvents, you don't need to create listeners manually :)
Calling a callback function is not highly recommended, check this example using a listener (Remember to remove all listeners from componentWillUnMount with this option)
Component A
navigateToComponentB() {
const { navigation } = this.props
this.navigationListener = navigation.addListener('willFocus', payload => {
this.removeNavigationListener()
const { state } = payload
const { params } = state
//update state with the new params
const { otherParam } = params
this.setState({ otherParam })
})
navigation.push('ComponentB', {
returnToRoute: navigation.state,
otherParam: this.state.otherParam
})
}
removeNavigationListener() {
if (this.navigationListener) {
this.navigationListener.remove()
this.navigationListener = null
}
}
componentWillUnmount() {
this.removeNavigationListener()
}
Commponent B
returnToComponentA() {
const { navigation } = this.props
const { routeName, key } = navigation.getParam('returnToRoute')
navigation.navigate({ routeName, key, params: { otherParam: 123 } })
}

If you make sure that this is the first event handler work, something like this might do the trick:
$('*').click(function(event) {
if (this === event.target) { // only fire this handler on the original element
alert('clicked');
}
});
Note that, if you have lots of elements in your page, this will be Really Very Slow, and it won't work for anything added dynamically.
You may also get that error when CSRF "token" for the active user session is out of date, even if the token was specified in ajax request.
Yes, you can do
git push https://username:[email protected]/file.git --all
in this case https://username:[email protected]/file.git
replace the origin
in git push origin --all

Regarding 0xCC
and 0xCD
in particular, these are relics from the Intel 8088/8086 processor instruction set back in the 1980s. 0xCC
is a special case of the software interrupt opcode INT
0xCD
. The special single-byte version 0xCC
allows a program to generate interrupt 3.
Although software interrupt numbers are, in principle, arbitrary, INT 3
was traditionally used for the debugger break or breakpoint function, a convention which remains to this day. Whenever a debugger is launched, it installs an interrupt handler for INT 3
such that when that opcode is executed the debugger will be triggered. Typically it will pause the currently running programming and show an interactive prompt.
Normally, the x86 INT
opcode is two bytes: 0xCD
followed by the desired interrupt number from 0-255. Now although you could issue 0xCD 0x03
for INT 3
, Intel decided to add a special version--0xCC
with no additional byte--because an opcode must be only one byte in order to function as a reliable 'fill byte' for unused memory.
The point here is to allow for graceful recovery if the processor mistakenly jumps into memory that does not contain any intended instructions. Multi-byte instructions aren't suited this purpose since an erroneous jump could land at any possible byte offset where it would have to continue with a properly formed instruction stream.
Obviously, one-byte opcodes work trivially for this, but there can also be quirky exceptions: for example, considering the fill sequence 0xCDCDCDCD
(also mentioned on this page), we can see that it's fairly reliable since no matter where the instruction pointer lands (except perhaps the last filled byte), the CPU can resume executing a valid two-byte x86 instruction CD CD
, in this case for generating software interrupt 205 (0xCD).
Weirder still, whereas CD CC CD CC
is 100% interpretable--giving either INT 3
or INT 204
--the sequence CC CD CC CD
is less reliable, only 75% as shown, but generally 99.99% when repeated as an int-sized memory filler.
A very simple thing I use:
try() {
"$@" || (e=$?; echo "$@" > /dev/stderr; exit $e)
}
Answer by @Ben proved to be useful for me. But I needed to check the product version as it was the main increment happening in my software and followed semantic versioning.
myFileVersionInfo.ProductVersion
This method met my expectations
Update: Instead of explicitly mentioning dll path in program (as needed in production version), we can get product version using Assembly.
Assembly assembly = Assembly.GetExecutingAssembly();
FileVersionInfo fileVersionInfo =FileVersionInfo.GetVersionInfo(assembly.Location);
string ProdVersion= fileVersionInfo.ProductVersion;
It's as simple as this:
unsigned int foo;
int bar = 10;
foo = (unsigned int)bar;
Or vice versa...
If you are storing keys/values as strings, then this will work:
HashMap<String, String> newMap = new HashMap<String, String>();
newMap.put("my_code", "shhh_secret");
String value = newMap.get("my_code");
The question is what gets populated in the HashMap (key & value)
No need to add commands anymore. For those who are new to Visual Studio Code and searching for an easy way to format code on saving, kindly follow the below steps.

in Mac or using the below screenshot.You are done. Thank you.
You can access any private field of an arbitrary type with code like this:
Foo foo = new Foo();
string c = foo.GetFieldValue<string>("_bar");
For that you need to define an extension method that will do the work for you:
public static class ReflectionExtensions {
public static T GetFieldValue<T>(this object obj, string name) {
// Set the flags so that private and public fields from instances will be found
var bindingFlags = BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance;
var field = obj.GetType().GetField(name, bindingFlags);
return (T)field?.GetValue(obj);
}
}
label {_x000D_
padding: 10px 0;_x000D_
position: relative;_x000D_
}
_x000D_
Add some padding-top and padding-bottom instead of height.
If you want to send the message to a predetermined person, such as yourself, you can set it so that the channel it would be messaging to would be their (your) own userID. So for instance, if you're using the discord bot tutorials from Digital Trends, where it says "to: ", you would continue with their (or your) userID. For instance, with how that specific code is set up, you could do "to: userID", and it would message that person. Or, if you want the bot to message you any time someone uses a specific command, you could do "to: '12345678890'", the numbers being a filler for the actual userID. Hope this helps!
Pug (renamed from 'Jade') is a templating engine for full stack web app development. It provides a neat and clean syntax for writing HTML and maintains strict whitespace indentation (like Python). It has been implemented with JavaScript APIs. The language mainly supports two iteration constructs: each and while. 'for' can be used instead 'each'. Kindly consult the language reference here:
https://pugjs.org/language/iteration.html
Here is one of my snippets: each/for iteration in pug_screenshot
import os
os.listdir("path") # returns list
Consider two class-typed variables:
class Boo { ... };
Boo b0; // mutable object
const Boo b1; // non-mutable object
Now you are able to call any member function of Boo
on b0
, but only const
-qualified member functions on b1
.
There is a simple function subtract
which moment library gives us to subtract time from some time.
Using it is also very simple.
moment(Date.now()).subtract(7, 'days'); // This will subtract 7 days from current time
moment(Date.now()).subtract(3, 'd'); // This will subtract 3 days from current time
//You can do this for days, years, months, hours, minutes, seconds
//You can also subtract multiple things simulatneously
//You can chain it like this.
moment(Date.now()).subtract(3, 'd').subtract(5. 'h'); // This will subtract 3 days and 5 hours from current time
//You can also use it as object literal
moment(Date.now()).subtract({days:3, hours:5}); // This will subtract 3 days and 5 hours from current time
Hope this helps!
Changing index.js
to index.ts
fixed this error for me. (I did not have any .ts
files before this).
Note: remember to change anywhere you reference index.js
to index.ts
except of course, where you reference your main file. By convention this is probably in your lib
or dist
folders.
My tsconfig.json:
{
"compilerOptions": {
"target": "es2016",
"module": "commonjs",
"outDir": "./dist",
"strict": true,
"esModuleInterop": true,
"inlineSourceMap": true,
"noImplicitAny": false
}
}
My outDir
is ./dist
so I reference my main in my package.json as "main": "dist/index.js"

With Kristina's answer as inspiration, I created an open source tool called Variety which does exactly this: https://github.com/variety/variety
Source code of CSS/JS we usually minified/compress. Now if we want to debug those minified files then we have to add following line at the end of minified file
/*# sourceMappingURL=bootstrap.min.css.map */
This tells compiler where is source file actually mapped.
In the case of JS its make sense
but in the case of CSS, its actually debugging of SCSS.
To Remove Warning: remove /*# sourceMappingURL=bootstrap.min.css.map */ from the end of minified file
, .
I've used this method successfully:
System.Reflection.Assembly.GetExecutingAssembly().CreateInstance(string className)
You'll need to cast the returned object to your desired object type.
For those who even yet have the problem, try enabling "Build project automatically" in the Java compiler settings and see if that makes a difference as it worked for me.
var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;
if (!isNaN(top)) {
$("#app_scroler").click(function () {
$('html, body').animate({
scrollTop: top
}, 100);
});
}
if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800
var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;
Alternative: Stream.concat()
Stream.concat(map.values().stream(), listContainer.lst.stream())
.collect(Collectors.toList()
If you don't want to wrap a table under any div:
table{
table-layout: fixed;
}
tbody{
display: block;
overflow: auto;
}
Now Java8 allows us to define even Static Methods in Interface.
interface X {
static void foo() {
System.out.println("foo");
}
}
class Y implements X {
//...
}
public class Z {
public static void main(String[] args) {
X.foo();
// Y.foo(); // won't compile because foo() is a Static Method of X and not Y
}
}
Note: Methods in Interface are still public abstract by default if we don't explicitly use the keywords default/static to make them Default methods and Static methods resp.

An alternative answer is,
sudo yum list \*java-1\* | grep open
than select one from list and install that
for example,
sudo yum install java-1.7.0-openjdk.x86_64
v-flex does not have a display flex! Inspect v-flex in your browser and you will find out it is just a simple block div.
So, you should override it with display: flex
in your HTML or CSS to make it work with justify-content.
As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils
module (Thanks Oliver)
Here is the proper way to do it:
#xlrd, xlutils and xlwt modules need to be installed.
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy
rb = open_workbook("names.xls")
wb = copy(rb)
s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')
This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.
Your script is right. But by default is of None type. So it considers true of any other value other than None is assigned to args.argument_name variable.
I would suggest you to add a action="store_true". This would make the True/False type of flag. If used its True else False.
import argparse
parser = argparse.ArgumentParser('parser-name')
parser.add_argument("-f","--flag",action="store_true",help="just a flag argument")
usage
$ python3 script.py -f
After parsing when checked with args.f it returns true,
args = parser.parse_args()
print(args.f)
>>>true
In java, there are two types of parameters, implicit parameters and explicit parameters. Explicit parameters are the arguments passed into a method. The implicit parameter of a method is the instance that the method is called from. Arguments are simply one of the two types of parameters.
I created a string extension for this, hope it helps.
public static string GetStringAfterChar(this string value, char substring)
{
if (!string.IsNullOrWhiteSpace(value))
{
var index = value.LastIndexOf(substring);
return index > 0 ? value.Substring(index + 1) : value;
}
return string.Empty;
}
Swift3
You can use subscript syntax to access the Character at a particular String index.
let greeting = "Guten Tag!"
let index = greeting.index(greeting.startIndex, offsetBy: 7)
greeting[index] // a
or we can do a String Extension in Swift 4
extension String {
func getCharAtIndex(_ index: Int) -> Character {
return self[self.index(self.startIndex, offsetBy: index)]
}
}
USAGE:
let foo = "ABC123"
foo.getCharAtIndex(2) //C
If you can hard-code the number of players
Player[] thePlayers = {
new Player(0),
new Player(1),
new Player(2),
new Player(3)
};
You have two typing errors in your code:
struct timeval,
should be
struct timeval
and after the printf()
parenthesis you need a semicolon.
Also, depending on the compiler, so simple a cycle might just be optimized out, giving you a time of 0 microseconds whatever you do.
Finally, the time calculation is wrong. You only take into accounts the seconds, ignoring the microseconds. You need to get the difference between seconds, multiply by one million, then add "after" tv_usec
and subtract "before" tv_usec
. You gain nothing by casting an integer number of seconds to a float.
I'd suggest checking out the man page for struct timeval
.
This is the code:
#include <stdio.h>
#include <sys/time.h>
int main (int argc, char** argv) {
struct timeval tvalBefore, tvalAfter; // removed comma
gettimeofday (&tvalBefore, NULL);
int i =0;
while ( i < 10000) {
i ++;
}
gettimeofday (&tvalAfter, NULL);
// Changed format to long int (%ld), changed time calculation
printf("Time in microseconds: %ld microseconds\n",
((tvalAfter.tv_sec - tvalBefore.tv_sec)*1000000L
+tvalAfter.tv_usec) - tvalBefore.tv_usec
); // Added semicolon
return 0;
}
I had this issue after my database was working fine for long time. It turned out it was some data corruption.
In the error log I had:

Create 2 apps and
In /initializers/env_variables.rb
if Rails.env == 'development'
ENV['FB_APP_ID'] = "HERE"
ENV["FB_SECRET"] = "HERE"
else
ENV['FB_APP_ID'] = "HERE"
ENV["FB_SECRET"] = "HERE"
end
In your test, you are comparing the two TestParent
beans, not the single TestedChild
bean.
Also, Spring proxies your @Configuration
class so that when you call one of the @Bean
annotated methods, it caches the result and always returns the same object on future calls.

I had the same issue, but it was resolved by going to gmail's security settings and Allowing Less Secure apps. The Code from Domenic & Donny works, but only if you enabled that setting
If you are signed in (to Google) you can follow this link and toggle "Turn on" for "Access for less secure apps"
Try this if this works for you
android:background="@drawable/drop_shadow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="3dp"
android:paddingTop="3dp"
android:paddingRight="4dp"
android:paddingBottom="5dp"
You cannot do it. C compiler cannot do such a complex thing on stack.
You have to use heap and dynamic allocation.
What you really need to do:
Use *access(boardAux, x, y, size) = 42 to interact with the matrix.
In my case (Xcode 6.1, iOS 8.2) I did not see the update in AppStore. I found Xcode 6.2 for download and pressed "Install". Then, it installed and asked for the update (more than 2 Gb). Xcode 6.2 works correctly with iOS 8.2 and iOS 8.1.2
Hopefully this tip will help somebody else...
Just fixed this issue. import c2 or import numpy was not working. Uninstalled the most current version of numpy. Tried to install numpy==1.15.2 just like specified above, did not work. Tried numpy==1.19.3 IT worked. I guess not all versions work perfectly with all versions of python and dependencies. So keep uninstalling and install one that works.
I was working with this a few days ago, and noticed that sometimes you will need to use the get()
function to print the results of your variable.
ie :
varnames = c('jan', 'feb', 'march')
file_names = list_files('path to multiple csv files saved on drive')
assign(varnames[1], read.csv(file_names[1]) # This will assign the variable
From there, if you try to print the variable varnames[1]
, it returns 'jan'.
To work around this, you need to do
print(get(varnames[1]))
In order to get Android device name you have to add only a single line of code:
android.os.Build.MODEL;
Found here: getting-android-device-name
If you think of the body of a loop as a subroutine, continue
is sort of like return
. The same keyword exists in C, and serves the same purpose. Here's a contrived example:
for(int i=0; i < 10; ++i) {
if (i % 2 == 0) {
continue;
}
System.out.println(i);
}
This will print out only the odd numbers.
What you want is not possible. You have to create two parameters, and bind them separately:
select p from Person p where p.forename = :forename and p.surname = :surname
...
query.setParameter("forename", name.getForename());
query.setParameter("surname", name.getSurname());
Be aware that, as written, Peter's solution will "accept" 0000
. If you want to validate numbers between 1000
and 999999
, then that is another problem :-)
^[1-9][0-9]{3,5}$
for example will block inserting 0
at the beginning of the string.
If you want to accept 0 padding, but only up to a lengh of 6, so that 001000
is valid, then it becomes more complex. If we use look-ahead then we can write something like
^(?=[0-9]{4,6}$)0*[1-9][0-9]{3,}$
This first checks if the string is long 4-6 (?=[0-9]{4,6}$)
, then skips the 0s 0*
and search for a non-zero [1-9]
followed by at least 3 digits [0-9]{3,}
.
