The packages at http://windows.php.net/download/ all contain the php\_intl.dll
which is located in the subdir ext/
.
All you have to do is to check if your extension_dir points to the right directory and add (or uncomment) the extension=php\_intl.dll
directive.
Run php --ini
and notice file path on Loaded Configuration File
.
Then run command like cat -n /etc/php/7.2/cli/php.ini | grep intl
to find if the extension is commented or not.
Then update loaded configuration file by commenting line by adding ;
such as ;extension=intl
This can happen when you install php-intl
package and also enable the same extension on php.ini
file.
You can't do this in C#. Use a const int
instead.
No. Java doesn't support default parameters like C++. You need to define a different method:
public int doSomething()
{
return doSomething(value1, value2);
}
You probably want a dict instead of separate variables. For example
d = {}
for i in range(3):
d["group" + str(i)] = self.getGroup(selected, header+i)
If you insist on actually modifying local variables, you could use the locals
function:
for i in range(3):
locals()["group"+str(i)] = self.getGroup(selected, header+i)
On the other hand, if what you actually want is to modify instance variables of the class you're in, then you can use the setattr
function
for i in group(3):
setattr(self, "group"+str(i), self.getGroup(selected, header+i)
And of course, I'm assuming with all of these examples that you don't just want a list:
groups = [self.getGroup(i,header+i) for i in range(3)]
While that particular idiom is common, even more common is for people to use =
when they mean ==
. The convention when you really mean the =
is to use an extra layer of parentheses:
while ((list = list->next)) { // yes, it's an assignment
>>> myDict
{'lastName': ['Stone', 'Lee'], 'age': ['12'], 'firstName': ['Alan', 'Mary-Ann'],
'address': ['34 Main Street, 212 First Avenue']}
>>> Set = set()
>>> not ['' for Key, Values in myDict.items() for Value in Values if 'Mary' in Value and Set.add(Key)] and list(Set)
['firstName']
As Gregg Lind suggested, you can use reword to be prompted to only change the commit message (and leave the commit intact otherwise):
git rebase -i HEAD~n
Here, n
is the list of last n commits.
For example, if you use git rebase -i HEAD~4
, you may see something like this:
pick e459d80 Do xyz
pick 0459045 Do something
pick 90fdeab Do something else
pick facecaf Do abc
Now replace pick with reword for the commits you want to edit the messages of:
pick e459d80 Do xyz
reword 0459045 Do something
reword 90fdeab Do something else
pick facecaf Do abc
Exit the editor after saving the file, and next you will be prompted to edit the messages for the commits you had marked reword, in one file per message. Note that it would've been much simpler to just edit the commit messages when you replaced pick
with reword
, but doing that has no effect.

First change the array to a string by using implode() function. E.g $number=array(1,2,3,4,5,...);
$stringofnumber=implode("|",$number);
then pass the string to a session. e.g $_SESSION['string']=$stringofnumber;
so when you go to the page where you want to use the array, just explode your string. e.g
$number=explode("|", $_SESSION['string']);
finally number is your array but remember to start array on the of each page.
This is all nicely lined up including the field label. Lining up the field label was the tricky part.

You can use xp_dirtree
It takes three parameters:
Path of a Root Directory, Depth up to which you want to get files and folders and the last one is for showing folders only or both folders and files.
EXAMPLE: EXEC xp_dirtree 'C:\', 2, 1
ASCII to int:
ord('a')
gives 97
And back to a string:
str(unichr(97))
chr(97)
gives 'a'
Bounds checked:
[a[index] for index in (1,2,5,20) if 0 <= index < len(a)]
# [11, 12, 15]
You can avoid rolling your own Component subclass completely by using the JXImagePanel class from the free SwingX libraries.
Use the bootstrap classes col-xx-#
and col-xx-offset-#
So what is happening here is your screen is getting divided into 12 columns. In col-xx-#
, #
is the number of columns you cover and offset is the number of columns you leave.
For xx
, in a general website, md
is preferred and if you want your layout to look the same in a mobile device, xs
is preferred.
With what I can make of your requirement,
<div class="row">
<div class="col-md-4">First Div</div>
<div class="col-md-8">Second DIV </div>
</div>
Should do the trick.
Your code is fine. There's no problem with returning Strings
in this manner.
In Java, a String
is a reference to an immutable object. This, coupled with garbage collection, takes care of much of the potential complexity: you can simply pass a String
around without worrying that it would disapper on you, or that someone somewhere would modify it.
If you don't mind me making a couple of stylistic suggestions, I'd modify the code like so:
public String time_to_string(long t) // time in milliseconds
{
if (t < 0)
{
return "-";
}
else
{
int secs = (int)(t/1000);
int mins = secs/60;
secs = secs - (mins * 60);
return String.format("%d:%02d", mins, secs);
}
}
As you can see, I've pushed the variable declarations as far down as I could (this is the preferred style in C++ and Java). I've also eliminated ans
and have replaced the mix of string concatenation and String.format()
with a single call to String.format()
.
There is one more way to achieve it:-
Private Sub UserForm_Initialize()
Dim list As Object
Set list = UserForm1.Controls.Add("Forms.ListBox.1", "hello", True)
With list
.Top = 30
.Left = 30
.Width = 200
.Height = 340
.ColumnHeads = True
.ColumnCount = 2
.ColumnWidths = "100;100"
.MultiSelect = fmMultiSelectExtended
.RowSource = "Sheet1!C4:D25"
End With End Sub
Here, I am using the range C4:D25 as source of data for the columns. It will result in both the columns populated with values.
The properties are self explanatory. You can explore other options by drawing ListBox in UserForm and using "Properties Window (F4)" to play with the option values.
Each row in /proc/$PID/maps
describes a region of contiguous virtual memory in a process or thread. Each row has the following fields:
address perms offset dev inode pathname
08048000-08056000 r-xp 00000000 03:0c 64593 /usr/sbin/gpm
-
will appear instead of the r
/w
/x
. If a region is not shared, it is private, so a p
will appear instead of an s
. If the process attempts to access memory in a way that is not permitted, a segmentation fault is generated. Permissions can be changed using the mprotect
system call.mmap
), this is the offset in the file where the mapping begins. If the memory was not mapped from a file, it's just 0.[heap]
, [stack]
, or [vdso]
. [vdso]
stands for virtual dynamic shared object. It's used by system calls to switch to kernel mode. Here's a good article about it: "What is linux-gate.so.1?"You might notice a lot of anonymous regions. These are usually created by mmap
but are not attached to any file. They are used for a lot of miscellaneous things like shared memory or buffers not allocated on the heap. For instance, I think the pthread library uses anonymous mapped regions as stacks for new threads.
Swift 4.1 and 5. We use queues in many places in our code. So, I created Threads class with all queues. If you don't want to use Threads class you can copy the desired queue code from class methods.
class Threads {
static let concurrentQueue = DispatchQueue(label: "AppNameConcurrentQueue", attributes: .concurrent)
static let serialQueue = DispatchQueue(label: "AppNameSerialQueue")
// Main Queue
class func performTaskInMainQueue(task: @escaping ()->()) {
DispatchQueue.main.async {
task()
}
}
// Background Queue
class func performTaskInBackground(task:@escaping () throws -> ()) {
DispatchQueue.global(qos: .background).async {
do {
try task()
} catch let error as NSError {
print("error in background thread:\(error.localizedDescription)")
}
}
}
// Concurrent Queue
class func perfromTaskInConcurrentQueue(task:@escaping () throws -> ()) {
concurrentQueue.async {
do {
try task()
} catch let error as NSError {
print("error in Concurrent Queue:\(error.localizedDescription)")
}
}
}
// Serial Queue
class func perfromTaskInSerialQueue(task:@escaping () throws -> ()) {
serialQueue.async {
do {
try task()
} catch let error as NSError {
print("error in Serial Queue:\(error.localizedDescription)")
}
}
}
// Perform task afterDelay
class func performTaskAfterDealy(_ timeInteval: TimeInterval, _ task:@escaping () -> ()) {
DispatchQueue.main.asyncAfter(deadline: (.now() + timeInteval)) {
task()
}
}
}
Example showing the use of main queue.
override func viewDidLoad() {
super.viewDidLoad()
Threads.performTaskInMainQueue {
//Update UI
}
}
Usually there is a dos2unix
command you can use for this. Just make sure you read the manual as the GNU and BSD versions differ on how they deal with the arguments.
BSD version:
dos2unix $FILENAME $FILENAME_OUT
mv $FILENAME_OUT $FILENAME
GNU version:
dos2unix $FILENAME
Alternatively, you can create your own dos2unix
with any of the proposed answers here, for example:
function dos2unix(){
[ "${!}" ] && [ -f "{$1}" ] || return 1;
{ echo ':set ff=unix';
echo ':wq';
} | vim "${1}";
}
Actually the apk file is just a zip archive, so you can try to rename the file to theappname.apk.zip
and extract it with any zip utility (e.g. 7zip).
The androidmanifest.xml
file and the resources will be extracted and can be viewed whereas the source code is not in the package - just the compiled .dex file ("Dalvik Executable")
There is no way you can delete a pull request yourself -- you and the repo owner (and all users with push access to it) can close it, but it will remain in the log. This is part of the philosophy of not denying/hiding what happened during development.
However, if there are critical reasons for deleting it (this is mainly violation of Github Terms of Service), Github support staff will delete it for you.
Whether or not they are willing to delete your PR for you is something you can easily ask them, just drop them an email at [email protected]
UPDATE: Currently Github requires support requests to be created here: https://support.github.com/contact
easiest way, I think download Eric, unzip go to sources, open python directory, drag the install script into the python icon, not folder, follow prompts
Working on Mac I followed the answer of Sean Patrick Floyd placing a settings.xml like above in my user folder /Users/user/.m2/
But this did not help. So I opened a Terminal and did a ls -la on the folder. This was showing
-rw-r--r--@
thus staff and everone can at least read the file. So I wondered if the message isn't wrong and if the real cause is the lack of write permissions. I set the file to:
-rw-r--rw-@
This did it. The message disappeared.
This will throw a NullPointerException
- as will any attempt to invoke an instance method on a null
reference - but in cases like this you should make an explicit check against null
:
if ((test != null) && !test.isEmpty())
This is much better, and clearer, than propagating an Exception
.
You can write a method that takes the type as a generic parameter:
void GenericProcessMessage<T>(T message)
{
MessageProcessor<T> processor = messageProcessors[typeof(T)]
as MessageProcessor<T>;
// Call method processor or whatever you need to do
}
Then you need a way to call the method with the correct generic argument. You can do this with reflection:
public void ProcessMessage(object message)
{
Type messageType = message.GetType();
MethodInfo method = this.GetType().GetMethod("GenericProcessMessage");
MethodInfo closedMethod = method.MakeGenericMethod(messageType);
closedMethod.Invoke(this, new object[] {message});
}
As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project
(dotnet new xunit
) you'll find coverlet reference already present in csproj
file because Coverlet
is the default coverage tool for every .NET Core and >= .NET 5 applications.
Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.
Example report:
While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.
Guide:
If you want code coverage in .xml files you can run any of these commands:
dotnet test --collect:"XPlat Code Coverage"
dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura
A more powerful and flexible example can be found here: C# File Upload with form fields, cookies and headers
The best solution to me is to create a client service that you'll instantiate with your token an use it to wrap axios
.
import axios from 'axios';
const client = (token = null) => {
const defaultOptions = {
headers: {
Authorization: token ? `Token ${token}` : '',
},
};
return {
get: (url, options = {}) => axios.get(url, { ...defaultOptions, ...options }),
post: (url, data, options = {}) => axios.post(url, data, { ...defaultOptions, ...options }),
put: (url, data, options = {}) => axios.put(url, data, { ...defaultOptions, ...options }),
delete: (url, options = {}) => axios.delete(url, { ...defaultOptions, ...options }),
};
};
const request = client('MY SECRET TOKEN');
request.get(PAGES_URL);
In this client, you can also retrieve the token from the localStorage / cookie, as you want.
Use the hasClass
method:
jQueryCollection.hasClass(className);
or
$(selector).hasClass(className);
The argument is (obviously) a string representing the class you are checking, and it returns a boolean (so it doesn't support chaining like most jQuery methods).
Note: If you pass a className
argument that contains whitespace, it will be matched literally against the collection's elements' className
string. So if, for instance, you have an element,
<span class="foo bar" />
then this will return true
:
$('span').hasClass('foo bar')
and these will return false
:
$('span').hasClass('bar foo')
$('span').hasClass('foo bar')
Use isinstance(obj, basestring)
for an object-to-test obj
.

I know this is an old question but it does not yet appear to have an answer. I've duplicated this situation, but I'm writing the server app, so I've been able to establish what happens on the server side as well. The client sends the certificate when the server asks for it and if it has a reference to a real certificate in the s_client command line. My server application is set up to ask for a client certificate and to fail if one is not presented. Here is the command line I issue:
Yourhostname here -vvvvvvvvvv
s_client -connect <hostname>:443 -cert client.pem -key cckey.pem -CAfile rootcert.pem -cipher ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH -tls1 -state
When I leave out the "-cert client.pem" part of the command the handshake fails on the server side and the s_client command fails with an error reported. I still get the report "No client certificate CA names sent" but I think that has been answered here above.
The short answer then is that the server determines whether a certificate will be sent by the client under normal operating conditions (s_client is not normal) and the failure is due to the server not recognizing the CA in the certificate presented. I'm not familiar with many situations in which two-way authentication is done although it is required for my project.
You are clearly sending a certificate. The server is clearly rejecting it.
The missing information here is the exact manner in which the certs were created and the way in which the provider loaded the cert, but that is probably all wrapped up by now.
Correct output:
'{"data":[{"id":"1","reason":"hello\\nworld"},{"id":"2","reason":"it\\nworks"}]}'
function json_entities( $data = null )
{
//stripslashes
return str_replace( '\n',"\\"."\\n",
htmlentities(
utf8_encode( json_encode( $data) ) ,
ENT_QUOTES | ENT_IGNORE, 'UTF-8'
)
);
}
Without any extra package, 3 being the number of groups:
> findInterval(das$wt, unique(quantile(das$wt, seq(0, 1, length.out = 3 + 1))), rightmost.closed = TRUE)
[1] 1 1 1 2 2 2 3 1 3 3 3 2 1 3 2
You can speed up the quantile computation by using a representative sample of the values of interest. Double check the documentation of the FindInterval
function.
You need to use the await keyword when use async and your function return type should be generic Here is an example with return value:
public async Task<object> MethodName()
{
return await Task.FromResult<object>(null);
}
Here is an example with no return value:
public async Task MethodName()
{
await Task.CompletedTask;
}

The properties on the style
object are only the styles applied directly to the element (e.g., via a style
attribute or in code). So .style.marginTop
will only have something in it if you have something specifically assigned to that element (not assigned via a style sheet, etc.).
To get the current calculated style of the object, you use either the currentStyle
property (Microsoft) or the getComputedStyle
function (pretty much everyone else).
Example:
var p = document.getElementById("target");
var style = p.currentStyle || window.getComputedStyle(p);
display("Current marginTop: " + style.marginTop);
Fair warning: What you get back may not be in pixels. For instance, if I run the above on a p
element in IE9, I get back "1em"
.
The TextWatcher
interface has 3 callbacks methods which are all called in the following order when a change occurred to the text:
beforeTextChanged(CharSequence s, int start, int count, int after)
s
parameter is the text before any change is applied.start
parameter is the position of the beginning of the changed part in the text.count
parameter is the length of the changed part in the s
sequence since the start
position.after
parameter is the length of the new sequence which will replace the part of the s
sequence from start
to start+count
.TextView
from this method (by using myTextView.setText(String newText)
).onTextChanged(CharSequence s, int start, int before, int count)`
beforeTextChanged
method but called after the text changes.s
parameter is the text after changes have been applied.start
parameter is the same as in the beforeTextChanged
method.count
parameter is the after
parameter in the beforeTextChanged method.before
parameter is the count
parameter in the beforeTextChanged method.TextView
from this method (by using myTextView.setText(String newText)
).afterTextChanged(Editable s)
TextView
from this method.TextView
, the TextWatcher
will be triggered again, starting an infinite loop. You should then add like a boolean _ignore
property which prevent the infinite loop.new TextWatcher() {
boolean _ignore = false; // indicates if the change was made by the TextWatcher itself.
@Override
public void afterTextChanged(Editable s) {
if (_ignore)
return;
_ignore = true; // prevent infinite loop
// Change your text here.
// myTextView.setText(myNewText);
_ignore = false; // release, so the TextWatcher start to listen again.
}
// Other methods...
}
TextViewListener
Personally, I made my custom text listener, which gives me the 4 parts in separate strings, which is, for me, much more intuitive to use.
/**

ETA 24 Apr 17
I wanted to simplify this a bit with some async
/await
magic, as it makes it a lot more succinct:
Using the same promisified-observable:
const startObservable = (domNode) => {
var targetNode = domNode;
var observerConfig = {
attributes: true,
childList: true,
characterData: true
};
return new Promise((resolve) => {
var observer = new MutationObserver(function (mutations) {
// For the sake of...observation...let's output the mutation to console to see how this all works
mutations.forEach(function (mutation) {
console.log(mutation.type);
});
resolve(mutations)
});
observer.observe(targetNode, observerConfig);
})
}
Your calling function can be as simple as:
const waitForMutation = async () => {
const button = document.querySelector('.some-button')
if (button !== null) button.click()
try {
const results = await startObservable(someDomNode)
return results
} catch (err) {
console.error(err)
}
}
If you wanted to add a timeout, you could use a simple Promise.race
pattern as demonstrated here:
const waitForMutation = async (timeout = 5000 /*in ms*/) => {
const button = document.querySelector('.some-button')
if (button !== null) button.click()
try {
const results = await Promise.race([
startObservable(someDomNode),
// this will throw after the timeout, skipping
// the return & going to the catch block
new Promise((resolve, reject) => setTimeout(
reject,
timeout,
new Error('timed out waiting for mutation')
)
])
return results
} catch (err) {
console.error(err)
}
}
Original
You can do this without libraries, but you'd have to use some ES6 stuff, so be cognizant of compatibility issues (i.e., if your audience is mostly Amish, luddite or, worse, IE8 users)
First, we'll use the MutationObserver API to construct an observer object. We'll wrap this object in a promise, and resolve()
when the callback is fired (h/t davidwalshblog)david walsh blog article on mutations:
const startObservable = (domNode) => {
var targetNode = domNode;
var observerConfig = {
attributes: true,
childList: true,
characterData: true
};
return new Promise((resolve) => {
var observer = new MutationObserver(function (mutations) {
// For the sake of...observation...let's output the mutation to console to see how this all works
mutations.forEach(function (mutation) {
console.log(mutation.type);
});
resolve(mutations)
});
observer.observe(targetNode, observerConfig);
})
}
Then, we'll create a generator function
. If you haven't used these yet, then you're missing out--but a brief synopsis is: it runs like a sync function, and when it finds a yield <Promise>
expression, it waits in a non-blocking fashion for the promise to be fulfilled (Generators do more than this, but this is what we're interested in here).
// we'll declare our DOM node here, too
let targ = document.querySelector('#domNodeToWatch')
function* getMutation() {
console.log("Starting")
var mutations = yield startObservable(targ)
console.log("done")
}
A tricky part about generators is they don't 'return' like a normal function. So, we'll use a helper function to be able to use the generator like a regular function. (again, h/t to dwb)
function runGenerator(g) {
var it = g(), ret;
// asynchronously iterate over generator
(function iterate(val){
ret = it.next( val );
if (!ret.done) {
// poor man's "is it a promise?" test
if ("then" in ret.value) {
// wait on the promise
ret.value.then( iterate );
}
// immediate value: just send right back in
else {
// avoid synchronous recursion
setTimeout( function(){
iterate( ret.value );
}, 0 );
}
}
})();
}
Then, at any point before the expected DOM mutation might happen, simply run runGenerator(getMutation)
.
Now you can integrate DOM mutations into a synchronous-style control flow. How bout that.

Basically, you do this to store a value in the Session object:
Session["FirstName"] = FirstNameTextBox.Text;
To retrieve the value:
var firstName = Session["FirstName"];
Use Decimal.Truncate
It removes the fractional part from the decimal.
int i = (int)Decimal.Truncate(12.66m)
See In eclipse, ctrl-click goes to the declaration of the method I clicked. For interfaces with one implementation, how can I just directly to that implementation? for some alternative solutions.
YurkamTim is right. It needs only a modification:
After function($) you need a pointer to the external variable by "use(&$searchedValue)" and then you can access the external variable. Also you can modify it.
$neededObject = array_filter(
$arrayOfObjects,
function ($e) use (&$searchedValue) {
return $e->id == $searchedValue;
}
);
The property you need is location.hash. For example:
location.hash = 'top'; //would jump to named anchor "top
I don't know how to do the nice scroll animation without the use of dojo or some toolkit like that, but if you just need it to jump to an anchor, location.hash should do it.

Assembly code is discussed here.
"An assembly language is a low-level language for programming computers. It implements a symbolic representation of the numeric machine codes and other constants needed to program a particular CPU architecture."
Machine code is discussed here.
"Machine code or machine language is a system of instructions and data executed directly by a computer's central processing unit."
Basically, assembler code is the language and it is translated to object code (the native code that the CPU runs) by an assembler (analogous to a compiler).
Use a double for the sum, otherwise you are doing an integer division and you won't get any decimals:
private double calculateAverage(List <Integer> marks) {
if (marks == null || marks.isEmpty()) {
return 0;
}
double sum = 0;
for (Integer mark : marks) {
sum += mark;
}
return sum / marks.size();
}
or using the Java 8 stream API:
return marks.stream().mapToInt(i -> i).average().orElse(0);
If you find yourself applying those 2 roles often you can wrap them in their own Authorize. This is really an extension of the accepted answer.
using System.Web.Mvc;
public class AuthorizeAdminOrMember : AuthorizeAttribute
{
public AuthorizeAdminOrMember()
{
Roles = "members, admin";
}
}
And then apply your new authorize to the Action. I think this looks cleaner and reads easily.
public class MyController : Controller
{
[AuthorizeAdminOrMember]
public ActionResult MyAction()
{
return null;
}
}
This is what worked for me -
When the hidden.bs.modal
event is fired, jQuery
's .remove()
function can remove the element that has .modal-backdrop
class. So each time the modal is closed, the modal-backdrop will be removed.
//setting callback function for 'hidden.bs.modal' event
$('#modal').on('hidden.bs.modal', function(){
//remove the backdrop
$('.modal-backdrop').remove();
})
Good Luck.
None of these answers worked for me, at least not for scrolling down a facebook search result page, but I found after a lot of testing this solution:

driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
Divs=driver.find_element_by_tag_name('div').text
if 'End of Results' in Divs:
print 'end'
break
else:

lots of correct answers, but as I landed here to copy & paste a folder rename with history, I found that this
git mv <old name> <new name>
will move the old folder (itself) to nest within the new folder
while
git mv <old name>/ <new name>
(note the '/') will move the nested content from the old folder to the new folder
both commands didn't copy along the history of nested files. I eventually renamed each nested folder individually ?
git mv <old name>/<nest-folder> <new name>/<nest-folder>
If you just put '/' in the href it will reload the current window.

If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web

There are many plugins for doing that. I normally use datatables it works great. http://datatables.net/

If you are using wamp stack, it will be fixed by open port in Firewall (Control Pannel). It work for my case (detail how to open port 80: https://tips.alocentral.com/open-tcp-port-80-in-windows-firewall/)
The following are some of the ways to remove docker images/containers:
docker rmi image_name:version/image-id
docker rmi $(docker images -qf "dangling=true")
docker rm $(docker kill $(docker ps -aq))
Note: Replace kill
with stop
for graceful shutdown
Use grep to remove all except my-image
and ubuntu
docker rmi $(docker images | grep -v 'ubuntu\|my-image' | awk {'print $3'})
Or (without awk)
docker rmi $(docker images --quiet | grep -v $(docker images --quiet ubuntu:my-image))
Did you try using the UIButton
from the Interface builder (that has rounded corners) and experimenting with the settings to make it look like a label. if all you want is to display static text within.
JSON does not know anything about dates. What .NET does is a non-standard hack/extension.
I would use a format that can be easily converted to a Date
object in JavaScript, i.e. one that can be passed to new Date(...)
. The easiest and probably most portable format is the timestamp containing milliseconds since 1970.
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;
and you leave it null
(0
) when persisting. (null
if you use the Integer
/ Long
wrappers)
In some cases the AUTO
strategy is resolved to SEQUENCE
rathen than to IDENTITY
or TABLE
, so you might want to manually set it to IDENTITY
or TABLE
(depending on the underlying database).
It seems SEQUENCE
+ specifying the sequence name worked for you.

Simplest way I found:

Try this:
Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row
Range("A2:L" & Lastrow).Select
Let's pretend that the value of Lastrow
is 50. When you use the following:
Range("A2:L2" & Lastrow).Select
Then it is selecting a range from A2 to L250.
You can use DataSet.Tables(0).Columns.Contains(name)
to check whether the DataTable
contains a column with a particular name.
Using ggplot
and a little dplyr
for data manipulation:
set.seed(42)
df <- data.frame(x = rep(1:10,each=5), y = rnorm(50))
library(ggplot2)
library(dplyr)
df.summary <- df %>% group_by(x) %>%
summarize(ymin = min(y),
ymax = max(y),
ymean = mean(y))
ggplot(df.summary, aes(x = x, y = ymean)) +
geom_point(size = 2) +
geom_errorbar(aes(ymin = ymin, ymax = ymax))
If there's an additional grouping column (OP's example plot has two errorbars per x value, saying the data is sourced from two files), then you should get all the data in one data frame at the start, add the grouping variable to the dplyr::group_by
call (e.g., group_by(x, file)
if file
is the name of the column) and add it as a "group" aesthetic in the ggplot, e.g., aes(x = x, y = ymean, group = file)
.
Add an Application Configuration File
item to your project (Right -Click Project > Add item). This will create a file called app.config
in your project.
Edit the file by adding entries like <add key="keyname" value="someValue" />
within the <appSettings>
tag.
Add a reference to the System.Configuration
dll, and reference the items in the config using code like ConfigurationManager.AppSettings["keyname"]
.
You can use varargs
public function yourFunction(Parameter... parameters)

I heartily recommended dbVis. The client runs on Mac, Windows and Linux and supports a variety of database servers, including PostgreSQL.
you try this code---

The existing answers will fail if the string is empty or only has one character. Options:
String substring = str.length() > 2 ? str.substring(str.length() - 2) : str;
or
String substring = str.substring(Math.max(str.length() - 2, 0));
That's assuming that str
is non-null, and that if there are fewer than 2 characters, you just want the original string.

Hash functions for algorithmic use have usually 2 goals, first they have to be fast, second they have to evenly distibute the values across the possible numbers. The hash function also required to give the all same number for the same input value.
if your values are strings, here are some examples for bad hash functions:
string[0]
- the ASCII characters a-Z are way more often then othersstring.lengh()
- the most probable value is 1Good hash functions tries to use every bit of the input while keeping the calculation time minimal. If you only need some hash code, try to multiply the bytes with prime numbers, and sum them.
This solution worked for me.
The problem with setting location.hash
is that the page will jump to that id if it's found on the page.
The problem with window.history.pushState
is that it adds an entry to the history for each tab the user clicks. Then when the user clicks the back
button, they go to the previous tab. (this may or may not be what you want. it was not what I wanted).
For me, replaceState
was the better option in that it only replaces the current history, so when the user clicks the back
button, they go to the previous page.
$('#tab-selector').tabs({
activate: function(e, ui) {
window.history.replaceState(null, null, ui.newPanel.selector);
}
});
Check out the History API docs on MDN.

I was getting the same error in python 3.4.3 too and I tried using the solutions mentioned here and elsewhere with no success.
Microsoft makes a compiler available for Python 2.7 but it didn't do me much good since I am on 3.4.3.
Python since 3.3 has transitioned over to 2010 and you can download and install Visual C++ 2010 Express for free here: https://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express
Here is the official blog post talking about the transition to 2010 for 3.3: http://blog.python.org/2012/05/recent-windows-changes-in-python-33.html
Because previous versions gave a different error for vcvarsall.bat I would double check the version you are using with "pip -V"
C:\Users\B>pip -V
pip 6.0.8 from C:\Python34\lib\site-packages (python 3.4)
As a side note, I too tried using the latest version of VC++ (2013) first but it required installing 2010 express.
From that point forward it should work for anyone using the 32 bit version, if you are on the 64 bit version you will then get the ValueError: ['path'] message because VC++ 2010 doesn't have a 64 bit compuler. For that you have to get the Microsoft SDK 7.1. I can't hyperlink the instruction for 64 bit because I am limited to 2 links per post but its at
Python PIP has issues with path for MS Visual Studio 2010 Express for 64-bit install on Windows 7
why is it that even managed languages provide a finally-block despite resources being deallocated automatically by the garbage collector anyway?
Actually, languages based on Garbage collectors need "finally" more. A garbage collector does not destroy your objects in a timely manner, so it can not be relied upon to clean up non-memory related issues correctly.
In terms of dynamically-allocated data, many would argue that you should be using smart-pointers.
However...
RAII moves the responsibility of exception safety from the user of the object to the designer
Sadly this is its own downfall. Old C programming habits die hard. When you're using a library written in C or a very C style, RAII won't have been used. Short of re-writing the entire API front-end, that's just what you have to work with. Then the lack of "finally" really bites.

I had simillar problem. After a big headache I found, that my ActionBarDrawerToggle was modifying the icon, also when it should not modify the icon (because I didn't give reference to toolbar to the toggle component). So in my NavigationDrawerFragment class (that handles the opening and closing) in setUp(...)
method I set
mDrawerToggle.setHomeAsUpIndicator(R.drawable.app_icon);
and finally it worked.
Just add disabled as a class on your anchor:
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b></a>
So all together something like:
<ul class="nav">
<li class="dropdown">
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><a href="#">Link 1</a></li>
<li><a href="#">Link 2</a></li>
</ul>
</li>
</ul>
img
{
max-width: 100%;
min-width: 300px;
height: auto;
}
Make sure the required dlls are exported (or copied manually) to the bin folder when building your application.
I don't think that you need to use each()
, you can use standard for loop
var children = $element.children().not(".pb-sortable-placeholder");
for (var i = 0; i < children.length; i++) {
var currentChild = children.eq(i);
// whatever logic you want
var oldPosition = currentChild.data("position");
}
this way you can have the standard for loop features like break
and continue
works by default
also, the debugging will be easier
If you have this error while you create segues with the view controllers not with the UI elements you have to change sender: Any?
to this
@IBAction func backButtonPressed(_ sender: Any) {
performSegue(withIdentifier: "goToMainScreen", sender: self)
}
It will work.
For this case: user signup form, user must choose a username that is not taken.
This means we have to create a customized validation rule, which will send async http request with remote server.
<input name="user_name" type="text" >
$("form").validate({
rules: {
'user_name': {
// here jquery validate will start a GET request, to
// /interface/users/is_username_valid?user_name=<input_value>
// the response should be "raw text", with content "true" or "false" only
remote: '/interface/users/is_username_valid'
},
},
class Interface::UsersController < ActionController::Base
def is_username_valid
render :text => !User.exists?(:user_name => params[:user_name])
end
end
Your XML is not entirely clear, but arrays XML can cause force closes if you make them numbers, and/or put white space in their definition.

This may be helpful to someone. If you copied and pasted your form data (which has the datepicker input box, ensure you do not inadvertently copy the class="hasDatepicker"
This means your input box should look like this:
<input id="dateChooser" name="dateChooser" type="text" value=""/>
NOT
<input id="dateChooser" name="dateChooser" type="text" value="" class="hasDatepicker">
I made that mistake inadvertently. Removing the class and allowing the jQuery UI call appeared to fix it.
Hope that helps someone!
Add below code in the onCreate function:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
And then override: @Override public boolean onOptionsItemSelected(MenuItem item){ onBackPressed(); return true; }
There's a new built-in solution for this in .NET 4 - IStructuralEquatable
static bool ByteArrayCompare(byte[] a1, byte[] a2)
{
return StructuralComparisons.StructuralEqualityComparer.Equals(a1, a2);
}
ABCPDF can do so as well -- check out http://www.websupergoo.com/helppdf6net/default.html
The folder is part of the URL you set when you create request
: "ftp://www.contoso.com/test.htm"
. If you use "ftp://www.contoso.com/wibble/test.htm"
then the file will be uploaded to a folder named wibble
.
You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory
to make the wibble
folder if it doesn't already exist.
RelativeLayout works the same way, the last image in the relative layout wins.
As the other answers mentioned, dispatch_async from the main thread is fine.
However, depending on your use case, there is a side effect that you may consider a disadvantage: since the block is scheduled on a queue, it won't execute until control goes back to the run loop, which will have the effect of delaying your block's execution.
For example,
NSLog(@"before dispatch async");
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"inside dispatch async block main thread from main thread");
});
NSLog(@"after dispatch async");
Will print out:
before dispatch async
after dispatch async
inside dispatch async block main thread from main thread
For this reason, if you were expecting the block to execute in-between the outer NSLog's, dispatch_async would not help you.
You could create a random number using FLOOR(RAND() * n) as randnum
(n is an integer), however if you do not need the same random number to be repeated then you will have to somewhat store in a temp table. So you can check it against with where randnum not in (select * from temptable)
...
Short answer - no.
You will only be charged for the time that your instance is up and running, in hour increments. If you are using other services in conjunction you may be charged for those but it would be separate from your server instance.
you need to use os.system
module to execute shell command
import os
os.system('command')
if you want to save the output for later use, you need to use subprocess
module
import subprocess
child = subprocess.Popen('command',stdout=subprocess.PIPE,shell=True)
output = child.communicate()[0]
No, that's not really possible, as
The goal of the MD5 and its family of hashing functions is
Think that you can get the MD5 of any string, even very long. And the MD5 is only 16 bytes long (32 if you write it in hexa to store or distribute it more easily). If you could reverse them, you'd have a magical compacting scheme.
This being said, as there aren't so many short strings (passwords...) used in the world, you can test them from a dictionary (that's called "brute force attack") or even google for your MD5. If the word is common and wasn't salted, you have a reasonable chance to succeed...
got the same error when trying to cross compile the raspberry pi kernel on ubunto 14.04.03 64bit under VM. the solution was found here:
-Install packages used for cross compiling on the Ubuntu box.
sudo apt-get install gcc-arm-linux-gnueabi make git-core ncurses-dev
-Download the toolchain
cd ~
git clone https://github.com/raspberrypi/tools
-Add the toolchain to your path
PATH=$PATH:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin
notice the x64 version in the path command
No, is not possible to downgrade a database. 10.50.1600 is the SQL Server 2008 R2 version. There is absolutely no way you can restore or attach this database to the SQL Server 2008 instance you are trying to restore on (10.00.1600 is SQL Server 2008). Your only options are:
I think you can use thread like demon-thread for reading your input and your output reader will already be in while loop in main thread so you can read and write at same time.You can modify your program like this:
Thread T=new Thread(new Runnable() {
@Override
public void run() {
while(true)
{
String input = scan.nextLine();
input += "\n";
try {
writer.write(input);
writer.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
} );
T.start();
and you can reader will be same as above i.e.
while ((line = reader.readLine ()) != null) {
System.out.println ("Stdout: " + line);
}
make your writer as final otherwise it wont be able to accessible by inner class.
For an advanced user text input is the best, if the user knows the date format, it is very fast. For a not so advanced user I suggest using a datepicker. Since usually you also have advanced and non-advanced users I suggest a combination of text input and datepicker.
Try this ...
StringRequest sr = new StringRequest(type,url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// valid response
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// error
}
}){
@Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("username", username);
params.put("password", password);
params.put("grant_type", "password");
return params;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<String, String>();
// Removed this line if you dont need it or Use application/json
// params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
The previous remarks about deleting or removing a connection are absolutely a possibility. But you can also get this error when you attempt to invoke a package that uses project level connections (instead of package level connections).
If you are using project level connections and still want to use dtexec, never fear there is a way. I would not recommend converting them to package level connections (assuming you created them as project level connections for a good reason).
You will need to deploy your SSIS project. Your SSIS server will need to have a catalog created (https://msdn.microsoft.com/en-us/library/gg471509.aspx). Once you have the catalog, in your SSIS project select Project->Deploy and follow the wizard. The result will be a *.ispac file generated in your SSIS solution folder/bin/Development
Now for the money command, instead of invoking your package with a simple: dtexec.exe /f "package.dtsx"
instead call it this way: dtexec.exe /project "<...>/project.ispac" /package "<...>/package.dtsx"
The ispac file has the project level connection info that is needed to execute your package and you should be set!
Old post, but I thought I would share my solution because there aren't many solutions out there for this issue.
If you're running an old Windows Server 2003 machine, you likely need to install a hotfix (KB938397).
This problem occurs because the Cryptography API 2 (CAPI2) in Windows Server 2003 does not support the SHA2 family of hashing algorithms. CAPI2 is the part of the Cryptography API that handles certificates.
https://support.microsoft.com/en-us/kb/938397
For whatever reason, Microsoft wants to email you this hotfix instead of allowing you to download directly. Here's a direct link to the hotfix from the email:
http://hotfixv4.microsoft.com/Windows Server 2003/sp3/Fix200653/3790/free/315159_ENU_x64_zip.exe
To prevent JUnit from instantiating your test base class just make it
public abstract class MyTestBaseClass { ... whatever... }
(@Ignore reports it as ignored which I reserve for temporarily ignored tests.)
These answers were very helpful. Thank you.
My contribution below adds an array where multiple days can return false (we're closed every Tuesday, Wednesday and Thursday). And I bundled the specific dates plus years and the no-weekends functions.
If you want weekends off, add [Saturday], [Sunday] to the closedDays array.
$(document).ready(function(){
$("#datepicker").datepicker({
beforeShowDay: nonWorkingDates,
numberOfMonths: 1,
minDate: '05/01/09',
maxDate: '+2M',
firstDay: 1
});
function nonWorkingDates(date){
var day = date.getDay(), Sunday = 0, Monday = 1, Tuesday = 2, Wednesday = 3, Thursday = 4, Friday = 5, Saturday = 6;
var closedDates = [[7, 29, 2009], [8, 25, 2010]];
var closedDays = [[Monday], [Tuesday]];
for (var i = 0; i < closedDays.length; i++) {
if (day == closedDays[i][0]) {
return [false];
}
}
for (i = 0; i < closedDates.length; i++) {
if (date.getMonth() == closedDates[i][0] - 1 &&
date.getDate() == closedDates[i][1] &&
date.getFullYear() == closedDates[i][2]) {
return [false];
}
}
return [true];
}
});
This problem is about SSL connection. When you try to connect to some resource https protocol requires to create secured connection. That means only your browser and website server know what data is being sent in requests bodies. This security is achieved by ssl certificates that stored on website and are being downloaded by your browser (or any other client, Spring RestTemplate with Apache Http Client behind in our case) with first connection to host. There are RSA256 encryption and many other cool things around. But in the end of a day: In case certificate is not registered or is invalid you will see certificate error (HTTPS connection is not secure). To fix certificate error website provider need to buy it for particular website or fix somehow e.g. https://www.register.com/ssl-certificates
Right way how problem can be solved
Not a right way how problem can be solved
import SSL certificate to Java cacerts (certificate storage)
keytool -importcert -trustcacerts -noprompt -storepass changeit -alias citrix -keystore "C:\Program Files\Java\jdk-11.0.2\lib\security\cacerts" -file citrix.cer
Dirty (Insecure) way how problem can be solved
make RestTemplate to ignore SSL verification
@Bean
public RestTemplateBuilder restTemplateBuilder(@Autowired SSLContext sslContext) {
return new RestTemplateBuilder() {
@Override
public ClientHttpRequestFactory buildRequestFactory() {
return new HttpComponentsClientHttpRequestFactory(
HttpClients.custom().setSSLSocketFactory(
new SSLConnectionSocketFactory(sslContext
, NoopHostnameVerifier.INSTANCE)).build());
}
};
}
@Bean
public SSLContext insecureSslContext() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
return SSLContexts.custom()
.loadTrustMaterial(null, (x509Certificates, s) -> true)
.build();
}
Adding to the answer of stackoverflowuser2010, in the general case you can just use
data = np.array([[1,1,1],[2,2,2],[3,3,3]])
vector = np.array([1,2,3])
data / vector.reshape(-1,1)
This will turn your vector into a column matrix/vector
. Allowing you to do the elementwise operations as you wish. At least to me, this is the most intuitive way going about it and since (in most cases) numpy will just use a view of the same internal memory for the reshaping it's efficient too.
code that works, but output is:
10
20
30
40
50
so:
List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
for (Integer number : myCoords) {
System.out.println(number);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
Don't worry...! Follow these below steps and you will get your signed .apk file. I was also worry about that, but these step get ride me off from the frustration. Steps to sign your application:
Right click on the project in Eclipse -> Android Tools -> Export Unsigned Application Package (like here we export our GoogleDriveApp.apk to Desktop)
Sign the application using your keystore and the jarsigner tool (follow below steps):
Open cmd-->change directory where your "jarsigner.exe" exist (like here in my system it exist at "C:\Program Files\Java\jdk1.6.0_17\bin"
Now enter belwo command in cmd:
jarsigner -verbose -keystore c:\users\android\debug.keystore c:\users\pir fahim\Desktops\GoogleDriveApp.apk my_keystore_alias
It will ask you to provide your password: Enter Passphrase for keystore: It will sign your apk.To verify that the signing is successful you can run:
jarsigner -verify c:\users\pir fahim\Desktops\GoogleDriveApp.apk
It should come back with: jar verified.
Method 2
If you are using eclipse with ADT, then it is simple to compiled, signed, aligned, and ready the file for distribution.what you have to do just follow this steps.
These steps will compiled, signed and zip aligned your project and now you are ready to distribute your project or upload at Google Play store.
Use
git apply patchfile
if possible.
patch -p1 < patchfile
has potential side-effect.
git apply
also handles file adds, deletes, and renames if they're described in the git diff
format, which patch
won't do. Finally, git apply
is an "apply all or abort all" model where either everything is applied or nothing is, whereas patch can partially apply patch files, leaving your working directory in a weird state.
Here is a one line lambda:
df[map(lambda x :x not in ['b'], list(df.columns))]

It can also be done using array_walk
:
function array_sum_values(array $input, $key) {
$sum = 0;
array_walk($input, function($item, $index, $params) {
if (!empty($item[$params[1]]))
$params[0] += $item[$params[1]];
}, array(&$sum, $key)
);
return $sum;
}
var_dump(array_sum_values($arr, 'gozhi'));
Not so readable like previous solutions but it works :)
Right click on drawable folder_new_file- click on advanced button_ link to file in the file system_ then click on browse. finish
It should also be mentioned, that Set-PSDebug is similar to the old-school echo on
batch command:
Set-PSDebug -Trace 1
This command will result in showing every line of the executing script:
When the
Trace
parameter has a value of1
, each line of script is traced as it runs. When the parameter has a value of2
, variable assignments, function calls, and script calls are also traced. If theStep
parameter is specified, you're prompted before each line of the script runs.
I don't have enough reputation to add in comments, so I just write some of my findings of this annoying TypeError here:
Basically, I think it's a bug in the json.dump()
function in Python 2 only - It can't dump a Python (dictionary / list) data containing non-ASCII characters, even you open the file with the encoding = 'utf-8'
parameter. (i.e. No matter what you do). But, json.dumps()
works on both Python 2 and 3.
To illustrate this, following up phihag's answer: the code in his answer breaks in Python 2 with exception TypeError: must be unicode, not str
, if data
contains non-ASCII characters. (Python 2.7.6, Debian):
import json
data = {u'\u0430\u0431\u0432\u0433\u0434': 1} #{u'?????': 1}
with open('data.txt', 'w') as outfile:
json.dump(data, outfile)
It however works fine in Python 3.
If you want to bring information from a database into a textarea tag for editing: The input tag not to display data that occupy several lines: rows no work, tag input is one line.
<!--input class="article-input" id="article-input" type="text" rows="5" value="{{article}}" /-->
The textarea tag has no value, but work fine with handlebars
<textarea class="article-input" id="article-input" type="text" rows="9" >{{article}}</textarea>
If your goal is to diallow multiple instaces of a form, consider following ...
public class MyForm : Form
{
private static MyForm alreadyOpened = null;
public MyForm()
{
// If the form already exists, and has not been closed
if (alreadyOpened != null && !alreadyOpened.IsDisposed)
{
alreadyOpened.Focus(); // Bring the old one to top
Shown += (s, e) => this.Close(); // and destroy the new one.
return;
}
// Otherwise store this one as reference
alreadyOpened = this;
// Initialization
InitializeComponent();
}
}

First set position
of the parent DIV to relative
(specifying the offset, i.e. left
, top
etc. is not necessary) and then apply position: absolute
to the child DIV with the offset you want.
It's simple and should do the trick well.
With Docker 1.13 (Q4 2016), you now have:
docker system prune -a
will delete ALL unused data (i.e., in order: containers stopped, volumes without containers and images with no containers).
docker system prune
without -a will remove (for images) only dangling images, or images without a tag, as commented by smilebomb.
See PR 26108 and commit 86de7c0, which are introducing a few new commands to help facilitate visualizing how much space the Docker daemon data is taking on disk and allowing for easily cleaning up "unneeded" excess.
docker system prune -a
WARNING! This will remove:
- all stopped containers
- all volumes not used by at least one container
- all images without at least one container associated to them
Are you sure you want to continue? [y/N] y
As wjv comments,
There is also
docker {container,image,volume,network} prune
, which may be used to remove unused instances of just one type of object.
Introduced in commit 913e5cb, only for Docker 1.13+.

Misconception Common misconception with column ordering is that, I should (or could) do the pushing and pulling on mobile devices, and that the desktop views should render in the natural order of the markup. This is wrong.
Reality Bootstrap is a mobile first framework. This means that the order of the columns in your HTML markup should represent the order in which you want them displayed on mobile devices. This mean that the pushing and pulling is done on the larger desktop views. not on mobile devices view..

I created an extension to show all the annotations using some code from here and there in swift. This will not show all annotations if they can't be shown even at maximum zoom level.
import MapKit
extension MKMapView {
func fitAllAnnotations() {
var zoomRect = MKMapRectNull;
for annotation in annotations {
let annotationPoint = MKMapPointForCoordinate(annotation.coordinate)
let pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1);
zoomRect = MKMapRectUnion(zoomRect, pointRect);
}

If you are producing the entire output yourself, you can use sprintf()
, e.g.
> sprintf("%.10f",0.25)
[1] "0.2500000000"
specifies that you want to format a floating point number with ten decimal points (in %.10f
the f
is for float and the .10
specifies ten decimal points).
I don't know of any way of forcing R's higher level functions to print an exact number of digits.
Displaying 100 digits does not make sense if you are printing R's usual numbers, since the best accuracy you can get using 64-bit doubles is around 16 decimal digits (look at .Machine$double.eps on your system). The remaining digits will just be junk.
<xsl:text disable-output-escaping="yes">& </xsl:text>
will do the trick.
for var index = self.indexOfObject(object); index != NSNotFound; index = self.indexOfObject(object)
is for loop in C-style and has been removed
Change your code to something like this to remove all similar object if it have looped:
let indexes = arrContacts.enumerated().filter { $0.element == contacts[indexPath.row] }.map{ $0.offset }
for index in indexes.reversed() {
arrContacts.remove(at: index)
}
is_numeric
returns true
for decimals and integers. So if your user lazily enters 1
instead of 1.00
it will still return true
:
echo is_numeric(1); // true
echo is_numeric(1.00); // true
You may wish to convert the integer to a decimal with PHP, or let your database do it for you.
For making a CORS request one must add headers to the request along with the same he needs to check of mode_header is enabled in Apache.
For enabling headers in Ubuntu:
sudo a2enmod headers
For php server to accept request from different origin use:
Header set Access-Control-Allow-Origin *
Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"
In the recent go versions from 1.14 onwards, we have to do go mod vendor
before building or running, since by default go appends -mod=vendor
to the go commands.
So after doing go mod vendor
, if we try to build, we won't face this issue.
Yes there is, as long as you are using a .xls
format spreadsheet (the default for Excel up to 2003). For Excel 2007 onwards, the default is .xlsx
, which is a fairly secure format, and this method will not work.
As Treb says, it's a simple comparison. One method is to simply swap out the password entry in the file using a hex editor (see Hex editors for Windows). Step by step example:
Copy the lines starting with the following keys:
CMG=....
DPB=...
GC=...
FIRST BACKUP the excel file you don't know the VBA password for, then open it with your hex editor, and paste the above copied lines from the dummy file.

The simplest solution would be (using 'upstream
' as the remote name referencing the original repo forked):
git remote add upstream /url/to/original/repo
git fetch upstream
git checkout master
git reset --hard upstream/master
git push origin master --force
(Similar to this GitHub page, section "What should I do if I’m in a bad situation?")
Be aware that you can lose changes done on the master
branch (both locally, because of the reset --hard
, and on the remote side, because of the push --force
).
An alternative would be, if you want to preserve your commits on master
, to replay those commits on top of the current upstream/master
.
Replace the reset part by a git rebase upstream/master
. You will then still need to force push.
See also "What should I do if I’m in a bad situation?"
A more complete solution, backing up your current work (just in case) is detailed in "Cleanup git master branch and move some commit to new branch".
See also "Pull new updates from original GitHub repository into forked GitHub repository" for illustrating what "upstream
" is.
Note: recent GitHub repos do protect the master
branch against push --force
.
So you will have to un-protect master
first (see picture below), and then re-protect it after force-pushing).
Note: on GitHub specifically, there is now (February 2019) a shortcut to delete forked repos for pull requests that have been merged upstream.

Short answer:
Restart your router, and this problem will be fixed. (But if your restart button is not working, you need to do a nine-step process to do the restart. Hitting the restart button is just one of them.)
Long answer: Let's learn how to restart the router.
telnet 192.168.1.1
Run these commands:
mount_root ## this remounts your partitions from read-only to read/write mode
firstboot ## This will reset your router after reboot
reboot -f ## And force reboot

When you are selecting INTO a variable and there are no records returned you should get a NO DATA FOUND error. I believe the correct way to write the above code would be to wrap the SELECT statement with it's own BEGIN/EXCEPTION/END block. Example:
...
v_final_grade NUMBER;
v_letter_grade CHAR(1);
BEGIN
BEGIN
SELECT final_grade
INTO v_final_grade
FROM enrollment
WHERE student_id = v_student_id
AND section_id = v_section_id;
EXCEPTION
WHEN NO_DATA_FOUND THEN
v_final_grade := NULL;
END;
CASE -- outer CASE
WHEN v_final_grade IS NULL THEN
...
CURDATE()
will give current date while NOW()
will give full date time.
Run the queries, and you will find out whats the difference between them.
SELECT NOW(); -- You will get 2010-12-09 17:10:18
SELECT CURDATE(); -- You will get 2010-12-09
You can scale image that will also reduce the size of your image. There is a library for it you can download and use it. https://github.com/niraj124124/Images-Files-scale-and-compress.git
How to use 1)Import the compressor-v1.0. jar to your project. 2)Add the below sample code to test. ResizeLimiter resize = ImageResizer.build(); resize.scale("inputImagePath", "outputImagePath",imageWidth, imageHeight); Many more methods are there according to your requirement

Too bad Oracle has limitations like these. Sure, the result for a column not in the GROUP BY would be random, but sometimes you want that. Silly Oracle, you can do this in MySQL/MSSQL.
BUT there is a work around for Oracle:
While the following line does not work
SELECT unique_id_col, COUNT(1) AS cnt FROM yourTable GROUP BY col_A;
You can trick Oracle with some 0's like the following, to keep your column in scope, but not group by it (assuming these are numbers, otherwise use CONCAT)
SELECT MAX(unique_id_col) AS unique_id_col, COUNT(1) AS cnt
FROM yourTable GROUP BY col_A, (unique_id_col*0 + col_A);
You could do, assuming you have an array with value and array length: arrayVal[i]
, arrayLength
:
int sum = 0;
for (int i = 0; i < arrayLength; i++) {
sum += arrayVal[i];
}
System.out.println("the sum is" + sum);
I hope this helps.
Ugly hack to fix it using some shell magic, not a great solution but might inspire others with similar problems :)

Got this same error recently in a python app using requests on ubuntu 14.04LTS, that I thought had been running fine (maybe it was and some update occurred). Doing the steps below fixed it for me:

man git-pull
More precisely, git pull runs git fetch with the given parameters and calls git merge to merge the retrieved branch heads into the current branch. With --rebase, it runs git rebase instead of git merge.

Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

This being a very old question but worth adding that I have just had a similar issue where a background colour on a footer
element in my case didn't show. I added a position: relative
which worked.
In some cases (e.g. unique list elements), set operations can be used.
>>> a=[2,3,4]
>>> set(a) - set([2,3]) != set(a)
True
>>>
Or, using set.isdisjoint(),
>>> not set(a).isdisjoint(set([2,3]))
True
>>> not set(a).isdisjoint(set([5,6]))
False
>>>
When you perform operations on Background thread and you want to update UI, you can not call or set anything from background thread. In case of WPF you need Dispatcher.BeginInvoke and in case of WinForms you need Invoke method.
WPF:
// assuming "this" is the window containing your progress bar..
// following code runs in background worker thread...
for(int i=0;i<count;i++)
{
DoSomething();
this.Dispatcher.BeginInvoke((Action)delegate(){
this.progressBar.Value = (int)((100*i)/count);
});
}
WinForms:
// assuming "this" is the window containing your progress bar..
// following code runs in background worker thread...
for(int i=0;i<count;i++)
{
DoSomething();
this.Invoke(delegate(){
this.progressBar.Value = (int)((100*i)/count);
});
}
for WinForms delegate may require some casting or you may need little help there, dont remember the exact syntax now.
In some cases, you may run into a problem of synchronization with this method.
I wrote the callback call inside a setTimeout
function, and it worked synchronously just fine =)
E.G:
function obterJson(callback) {
jqxhr = $.getJSON(window.location.href + "js/data.json", function(data) {
setTimeout(function(){
callback(data);
},0);
}
Create WScript.Shell object and invoke Run() method on it.

It would be great to use axios for the api request which supports cancellation, interceptors etc. Along with axios, l use react-redux for state management and redux-saga/redux-thunk for the side effects.
cmake's ExternalProject_Add
indeed can used, but what I did not like about it - is that it performs something during build, continuous poll, etc... I would prefer to build project during build phase, nothing else. I have tried to override ExternalProject_Add
in several attempts, unfortunately without success.
Then I have tried also to add git submodule, but that drags whole git repository, while in certain cases I need only subset of whole git repository. What I have checked - it's indeed possible to perform sparse git checkout, but that require separate function, which I wrote below.
#-----------------------------------------------------------------------------

I have added two function calls below just to illustrate how to use the function.
Someone might not like to checkout master / trunk, as that one might be broken - then it's always possible to specify specific tag.
Checkout will be performed only once, until you clear the cache folder.
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
ch1 = (DataGridViewCheckBoxCell)dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[0];
if (ch1.Value == null)
ch1.Value=false;
switch (ch1.Value.ToString())
{
case "True":
ch1.Value = false;
break;
case "False":
ch1.Value = true;
break;
}
MessageBox.Show(ch1.Value.ToString());
}
best solution to find if the checkbox in the datagridview is checked or not.
Normally there's no need for that. First of all
echo $CLASSPATH
If there's something in there, you probably want to check Applications -> Utilites -> Java.

The query below would return the NO_OF_RESULTS you would like to be returned..
curl -XGET 'localhost:9200/foo/_search?size=NO_OF_RESULTS' -d '
{
"query" : {
"match_all" : {}
}
}'
Now, the question here is that you want all the records to be returned. So naturally, before writing a query, you wont know the value of NO_OF_RESULTS.
How do we know how many records exist in your document? Simply type the query below
curl -XGET 'localhost:9200/foo/_search' -d '
This would give you a result that looks like the one below
{
hits" : {
"total" : 2357,
"hits" : [
{
..................
The result total tells you how many records are available in your document. So, that's a nice way to know the value of NO_OF RESULTS
curl -XGET 'localhost:9200/_search' -d '
Search all types in all indices
curl -XGET 'localhost:9200/foo/_search' -d '
Search all types in the foo index
curl -XGET 'localhost:9200/foo1,foo2/_search' -d '
Search all types in the foo1 and foo2 indices
curl -XGET 'localhost:9200/f*/_search
Search all types in any indices beginning with f
curl -XGET 'localhost:9200/_all/type1,type2/_search' -d '
Search types user and tweet in all indices
var root = document.createElement("div");
root.innerHTML = "My name is <b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";
var texts = [].map.call( root.querySelectorAll("b"), function(v){
return v.textContent || v.innerText || "";
});
//["Bob", "20", "programming"]
ls -l $file | awk '{print $6}'

I have been in similar situation before. In Command prompt, you type 'start-ssh-agent' and voila! The ssh-agent will be started. Input the passphrase if it asked you.
I had the same issue I solved it like that:
axios.delete(url, {data:{username:"user", password:"pass"}, headers:{Authorization: "token"}})
If you are looking to reduce the size using coding itself, you can follow this code in php.
<?php
function compress($source, $destination, $quality) {
$info = getimagesize($source);
if ($info['mime'] == 'image/jpeg')
$image = imagecreatefromjpeg($source);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source);
imagejpeg($image, $destination, $quality);
return $destination;
}
$source_img = 'source.jpg';
$destination_img = 'destination .jpg';
$d = compress($source_img, $destination_img, 90);
?>
$d = compress($source_img, $destination_img, 90);
This is just a php function that passes the source image ( i.e., $source_img
), destination image ( $destination_img
) and quality for the image that will take to compress ( i.e., 90 ).
$info = getimagesize($source);
The getimagesize()
function is used to find the size of any given image file and return the dimensions along with the file type.
You can use contains:
string[] example = { "sample1", "sample2" };
var result = (from c in example where c.Contains("2") select c);
// returns only sample2
Android comes with a built-in YesNoPreference class that does exactly what you want (a confirm dialog with yes and no options). See the official source code here.
Unfortunately, it is in the com.android.internal.preference
package, which means it is a part of Android's private APIs and you cannot access it from your application (private API classes are subject to change without notice, hence the reason why Google does not let you access them).
Solution: just re-create the class in your application's package by copy/pasting the official source code from the link I provided. I've tried this, and it works fine (there's no reason why it shouldn't).
You can then add it to your preferences.xml
like any other Preference. Example:
<com.example.myapp.YesNoPreference
android:dialogMessage="Are you sure you want to revert all settings to their default values?"
android:key="com.example.myapp.pref_reset_settings_key"
android:summary="Revert all settings to their default values."
android:title="Reset Settings" />
Which looks like this:
If using in fragment then simply write
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
// Do something on UiThread
}
});
I have jus implement this library:https://github.com/jose78/go-collection. This is an example about how to use the Foreach loop:
package main
import (
"fmt"
col "github.com/jose78/go-collection/collections"
)
type user struct {
name string
age int
id int
}
func main() {
newList := col.ListType{user{"Alvaro", 6, 1}, user{"Sofia", 3, 2}}
newList = append(newList, user{"Mon", 0, 3})
newList.Foreach(simpleLoop)
if err := newList.Foreach(simpleLoopWithError); err != nil{
fmt.Printf("This error >>> %v <<< was produced", err )
}
}
var simpleLoop col.FnForeachList = func(mapper interface{}, index int) {
fmt.Printf("%d.- item:%v\n", index, mapper)
}
var simpleLoopWithError col.FnForeachList = func(mapper interface{}, index int) {
if index > 1{
panic(fmt.Sprintf("Error produced with index == %d\n", index))
}
fmt.Printf("%d.- item:%v\n", index, mapper)
}
The result of this execution should be:
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}
2.- item:{Mon 0 3}
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}

Since Go 1.11+, GOPATH is no longer recommended, the new way is using Go Modules.
simple
:Create a directory:
mkdir simple
cd simple
Create a new module:
go mod init github.com/username/simple
# Here, the module name is: github.com/username/simple.
# You're free to choose any module name.
# It doesn't matter as long as it's unique.
# It's better to be a URL: so it can be go-gettable.
Put all your files in that directory.
Finally, run:
go run .
Alternatively, you can create an executable program by building it:
go build .
# then:
./simple # if you're on xnix
# or, just:
simple # if you're on Windows
For more information, you may read this.
Go has included support for versioned modules as proposed here since 1.11. The initial prototype vgo was announced in February 2018. In July 2018, versioned modules landed in the main Go repository. In Go 1.14, module support is considered ready for production use, and all users are encouraged to migrate to modules from other dependency management systems.
A backslash needs to be escaped with another backslash.

Java enums are not like C or C++ enums, which are really just labels for integers.
Java enums are implemented more like classes - and they can even have multiple attributes.
public enum Ids {
OPEN(100), CLOSE(200);
private final int id;
Ids(int id) { this.id = id; }
public int getValue() { return id; }
}
The big difference is that they are type-safe which means you don't have to worry about assigning a COLOR enum to a SIZE variable.
See http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html for more.

PowerShell doesn't really provide any alternative to separate programs for either, but for structured data Out-Grid

Head

using the -First

Sed

.
However as PowerShell passes (.NET) objects – with all their typed structure, eg. dates remain DateTime
instances – rather than just strings, which each command needs to parse itself, much of sed
and other such programs are redundant.

Beautiful! Your solution was 99%... instead of "this.scrollY", I used "$(window).scrollTop()". What's even better is that this solution only requires the jQuery1.2.6 library (no additional libraries needed).
The reason I wanted that version in particular is because that's what ships with MVC currently.
Here's the code:
$(document).ready(function() {
$("#topBar").css("position", "absolute");
});
$(window).scroll(function() {
$("#topBar").css("top", $(window).scrollTop() + "px");
});
string x ="Hi ,World";
string y = x;
char[] whitespace = new char[]{ ' ',\t'};
string[] fooArray = y.Split(whitespace); // now you have an array of 3 strings
y = String.Join(" ", fooArray);
string[] target = { "Hi", "World", "VW_Slep" };
for (int i = 0; i < target.Length; i++)
{
string v = target[i];
string results = Array.Find(fooArray, element => element.StartsWith(v, StringComparison.Ordinal));
//
if (results != null)
{ MessageBox.Show(results); }
}
Here’s some code you can use to get a list of all the open windows. Actually, you get a dictionary where each item is a KeyValuePair where the key is the handle (hWnd) of the window and the value is its title. It also finds pop-up windows, such as those created by MessageBox.Show
.
using System.Runtime.InteropServices;
using HWND = System.IntPtr;
/// <summary>Contains functionality to get all the open windows.</summary>
public static class OpenWindowGetter
{
/// <summary>Returns a dictionary that contains the handle and title of all the open windows.</summary>
/// <returns>A dictionary that contains the handle and title of all the open windows.</returns>
public static IDictionary<HWND, string> GetOpenWindows()
{
HWND shellWindow = GetShellWindow();
Dictionary<HWND, string> windows = new Dictionary<HWND, string>();
EnumWindows(delegate(HWND hWnd, int lParam)
{
if (hWnd == shellWindow) return true;
if (!IsWindowVisible(hWnd)) return true;
int length = GetWindowTextLength(hWnd);
if (length == 0) return true;
StringBuilder builder = new StringBuilder(length);
GetWindowText(hWnd, builder, length + 1);
windows[hWnd] = builder.ToString();
return true;
}, 0);
return windows;
}
private delegate bool EnumWindowsProc(HWND hWnd, int lParam);
[DllImport("USER32.DLL")]
private static extern bool EnumWindows(EnumWindowsProc enumFunc, int lParam);
[DllImport("USER32.DLL")]
private static extern int GetWindowText(HWND hWnd, StringBuilder lpString, int nMaxCount);
[DllImport("USER32.DLL")]
private static extern int GetWindowTextLength(HWND hWnd);
[DllImport("USER32.DLL")]
private static extern bool IsWindowVisible(HWND hWnd);
[DllImport("USER32.DLL")]
private static extern IntPtr GetShellWindow();
}
And here’s some code that uses it:
foreach(KeyValuePair<IntPtr, string> window in OpenWindowGetter.GetOpenWindows())
{
IntPtr handle = window.Key;
string title = window.Value;
Console.WriteLine("{0}: {1}", handle, title);
}
So I was having a similar issue and I managed to solve it by putting the script tag with my JS file after the closing body tag.
I assume it's because it makes sure there's something to reference, but I am not entirely sure.
I have JSONObject like this: {"status":[{"Response":"success"}]}
.
If I want to convert the JSONObject value, which is a JSONArray into JSONObject automatically without using any static value, here is the code for that.
JSONArray array=new JSONArray();
JSONObject obj2=new JSONObject();
obj2.put("Response", "success");
array.put(obj2);
JSONObject obj=new JSONObject();
obj.put("status",array);
Converting the JSONArray to JSON Object:
Iterator<String> it=obj.keys();
while(it.hasNext()){
String keys=it.next();
JSONObject innerJson=new JSONObject(obj.toString());
JSONArray innerArray=innerJson.getJSONArray(keys);
for(int i=0;i<innerArray.length();i++){
JSONObject innInnerObj=innerArray.getJSONObject(i);
Iterator<String> InnerIterator=innInnerObj.keys();
while(InnerIterator.hasNext()){
System.out.println("InnInnerObject value is :"+innInnerObj.get(InnerIterator.next()));
}
}
Since the answers deviate I decided to test this and post the result - including the test example.
The server here just writes data to a client and does not expect any input.
The server:
ServerSocket serverSocket = new ServerSocket(4444);
Socket clientSocket = serverSocket.accept();
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
while (true) {
out.println("output");
if (out.checkError()) System.out.println("ERROR writing data to socket !!!");
System.out.println(clientSocket.isConnected());
System.out.println(clientSocket.getInputStream().read());
// thread sleep ...
// break condition , close sockets and the like ...
}
If you are just interested in the use of Access-Control-Allow-Origin:*
You can do that with this .htaccess
file at the site root.
Header set Access-Control-Allow-Origin "*"
Some useful information here: http://enable-cors.org/server_apache.html
An alternative that worked for me is to tell Maven to use http: instead of https: when using Maven Central by adding the following to settings.xml:
<settings>
.
.
.
<mirrors>
<mirror>
<id>central-no-ssl</id>
<name>Central without ssl</name>
<url>http://repo.maven.apache.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
.
.
.
</settings>
Your mileage may vary of course.
