I've compared performance (space and time) for a number of ways to store numpy arrays. Few of them support multiple arrays per file, but perhaps it's useful anyway.
Npy and binary files are both really fast and small for dense data. If the data is sparse or very structured, you might want to use npz with compression, which'll save a lot of space but cost some load time.
If portability is an issue, binary is better than npy. If human readability is important, then you'll have to sacrifice a lot of performance, but it can be achieved fairly well using csv (which is also very portable of course).
More details and the code are available at the github repo.
You don't need --header "Content-Length: $LENGTH".
curl --request POST --data-binary "@template_entry.xml" $URL
Note that GET request does not support content body widely.
Also remember that POST request have 2 different coding schema. This is first form:
$ nc -l -p 6666 & $ curl --request POST --data-binary "@README" http://localhost:6666 POST / HTTP/1.1 User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6 Host: localhost:6666 Accept: */* Content-Length: 9309 Content-Type: application/x-www-form-urlencoded Expect: 100-continue .. -*- mode: rst; coding: cp1251; fill-column: 80 -*- .. rst2html.py README README.html .. contents::
You probably request this:
-F/--form name=content (HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content- Type multipart/form-data according to RFC2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.
If you're dealing with files above 2 GB, you'll find that the above methods fail.
It's much easier just to hand the stream off to MD5 and allow that to chunk your file for you:
private byte[] computeFileHash(string filename)
{
MD5 md5 = MD5.Create();
using (FileStream fs = new FileStream(filename, FileMode.Open))
{
byte[] hash = md5.ComputeHash(fs);
return hash;
}
}
The answer of @alexandre with base64 does the trick.
The explanation why that works for IE is here
https://en.m.wikipedia.org/wiki/Data_URI_scheme
Under header 'format' where it says
Some browsers (Chrome, Opera, Safari, Firefox) accept a non-standard ordering if both ;base64 and ;charset are supplied, while Internet Explorer requires that the charset's specification must precede the base64 token.
Maybe encode them into a known set - something like base 64 is a popular choice.
Easiest way to do this with Chartjs. Just add below line in options:
pieceLabel: {
fontColor: '#000'
}
Best of luck
With synchronized blocks, you can have multiple synchronizers, so that multiple simultaneous but non-conflicting things can go on at the same time.
%
(any host) (see manual for details)The current problem is the first one, but right after you resolve it you will likely get the second one.
If your page is refreshed on submitting - yes, but only through the querystring: http://www.bloggingdeveloper.com/post/JavaScript-QueryString-ParseGet-QueryString-with-Client-Side-JavaScript.aspx (You must use method "GET" then). Else, you can return its value from the php script.
A standard prolog predicate will do this.
isfive(5).
will evaluate to true if you call it with 5 and fail(return false) if you run it with anything else. For not equal you use \=
isNotEqual(A,B):- A\=B.
Technically it is does not unify, but it is similar to not equal.
Learn Prolog Now is a good website for learning prolog.
Edit: To add another example.
isEqual(A,A).
I know this is an old question but I came across this today since I needed to test for this in my site. It seems the answers above are needlessly complicated. To establish the site protocol, all you have to do is test $_SERVER['HTTPS']
If the protocol is using HTTPS, then $_SERVER['HTTPS']
will return 'on'. If not, the variable will remain empty.
For example:
// test if HTTPS is being used. If it is, the echo will return '$SSL_test: on'. If not HTTPS, '$SSL_test' will remain empty.
$SSL_test = $_SERVER['HTTPS'];
echo '<p>$SSL_test: '.$SSL_test.'</p>';
if($SSL_test == true) {
echo 'You\'re using SSL';
} else {
echo 'You\'re not using SSL';
}
You can use the above to easily and cleanly test for HTTPS and implement accordingly. :)
Try this:
$(document).bind("contextmenu",function(e){
return false;
});
I just wanted to extend Alex's great answer to make it appropriate if you happen to want to duplicate an entire set of records:
SET @x=7;
CREATE TEMPORARY TABLE tmp SELECT * FROM invoices;
UPDATE tmp SET id=id+@x;
INSERT INTO invoices SELECT * FROM tmp;
I just had to do this and found Alex's answer a perfect jumping off point!. Of course, you have to set @x to the highest row number in the table (I'm sure you could grab that with a query). This is only useful in this very specific situation, so be careful using it when you don't wish to duplicate all rows. Adjust the math as necessary.
To conditionally check the length of the string, use CASE
.
SELECT CASE WHEN LEN(comments) <= 60
THEN comments
ELSE LEFT(comments, 60) + '...'
END As Comments

This question doesn't really have anything to do with how require()
works. Basically, whatever you set module.exports
to in your module will be returned from the require()
call for it.
This would be equivalent to:
var square = function(width) {
return {
area: function() {
return width * width;
}
};
}
There is no need for the new
keyword when calling square
. You aren't returning the function instance itself from square
, you are returning a new object at the end. Therefore, you can simply call this function directly.
For more intricate arguments around new
, check this out: Is JavaScript's "new" keyword considered harmful?
In order to delete a cookie set the expires
date to something in the past. A function that does this would be.
var delete_cookie = function(name) {
document.cookie = name + '=;expires=Thu, 01 Jan 1970 00:00:01 GMT;';
};
Then to delete a cookie named roundcube_sessauth
just do.
delete_cookie('roundcube_sessauth');
There isn't a single answer to this question as there are too many variables, but SHA2 is not yet really cracked (see: Lifetimes of cryptographic hash functions) so it is still a good algorithm to use to store passwords in. The use of salt is good because it prevents attack from dictionary attacks or rainbow tables. Importance of a salt is that it should be unique for each password. You can use a format like [128-bit salt][512-bit password hash] when storing the hashed passwords.
The only viable way to attack is to actually calculate hashes for different possibilities of password and eventually find the right one by matching the hashes.
To give an idea about how many hashes can be done in a second, I think Bitcoin is a decent example. Bitcoin uses SHA256 and to cut it short, the more hashes you generate, the more bitcoins you get (which you can trade for real money) and as such people are motivated to use GPUs for this purpose. You can see in the hardware overview that an average graphic card that costs only $150 can calculate more than 200 million hashes/s. The longer and more complex your password is, the longer time it will take. Calculating at 200M/s, to try all possibilities for an 8 character alphanumberic (capital, lower, numbers) will take around 300 hours. The real time will most likely less if the password is something eligible or a common english word.
As such with anything security you need to look at in context. What is the attacker's motivation? What is the kind of application? Having a hash with random salt for each gives pretty good protection against cases where something like thousands of passwords are compromised.
One thing you can do is also add additional brute force protection by slowing down the hashing procedure. As you only hash passwords once, and the attacker has to do it many times, this works in your favor. The typical way to do is to take a value, hash it, take the output, hash it again and so forth for a fixed amount of iterations. You can try something like 1,000 or 10,000 iterations for example. This will make it that many times times slower for the attacker to find each password.
Several years ago, the float
property used to solve that problem with the table
approach using display: table;
and display: table-row;
and display: table-cell;
.
But now with the flex property, you can solve it with 3 lines of code: display: flex;
and flex-wrap: wrap;
and flex: 1 0 50%;
.parent {
display: flex;
flex-wrap: wrap;
}
.child {
// flex: flex-grow flex-shrink flex-basis;
flex: 1 0 50%;
}
1 0 50%
are the flex
values we gave to: flex-grow flex-shrink flex-basis
respectively. It's a relatively new shortcut in flexbox to avoid typing them individually. I hope this helps someone out there
You can't. This is an open issue in TypeScript: https://github.com/Microsoft/TypeScript/issues/19573
Backtrace dumps a whole lot of garbage that you don't need. It takes is very long, difficult to read. All you usuall ever want is "what called what from where?" Here is a simple static function solution. I usually put it in a class called 'debug', which contains all of my debugging utility functions.
class debugUtils {
public static function callStack($stacktrace) {
print str_repeat("=", 50) ."\n";
$i = 1;
foreach($stacktrace as $node) {
print "$i. ".basename($node['file']) .":" .$node['function'] ."(" .$node['line'].")\n";
$i++;
}
}
}
You call it like this:
debugUtils::callStack(debug_backtrace());
And it produces output like this:

Here's how you do it for SQL Server. Someone else can translate it to MySQL. Parsing CSV Values Into Multiple Rows.
SELECT Author,
NullIf(SubString(',' + Phrase + ',' , ID , CharIndex(',' , ',' + Phrase + ',' , ID) - ID) , '') AS Word
FROM Tally, Quotes
WHERE ID <= Len(',' + Phrase + ',') AND SubString(',' + Phrase + ',' , ID - 1, 1) = ','
AND CharIndex(',' , ',' + Phrase + ',' , ID) - ID > 0
The idea is to cross join to a predefined table Tally which contains integer 1 through 8000 (or whatever big enough number) and run SubString
to find the right ,word, position.
Yes, if you really want / need to do it you can use PowerMock. This should be considered a last resort. With PowerMock you can cause it to return a mock from the call to the constructor. Then do the verify on the mock. That said, csturtz's is the "right" answer.
Here is the link to Mock construction of new objects
You can jump through hoops and convert your solution to a lapply

or apply
call. (I see @jonw shows one way to do this.) Other than that what you have already is perfectly acceptable code.
If these are all a time series or similar then the following might be a suitable alternative, which plots each series in it's own panel on a single plotting region. We use the zoo
package as it handles ordered data like this very well indeed.
require(zoo)
set.seed(1)
## example data
dat <- data.frame(X = cumsum(rnorm(100)), Y = cumsum(rnorm(100)),
Z = cumsum(rnorm(100)))
## convert to multivariate zoo object
datz <- zoo(dat)
## plot it
plot(datz)

Try using pandoc
pandoc -f html -t docx -o output.docx input.html
If the input or output format is not specified explicitly, pandoc will attempt to guess it from the extensions of the input and output filenames.

So you can even use
pandoc -o output.docx input.html
Problem Solved,
I edited the file /etc/postfix/master.cf
and commented
-o smtpd_relay_restrictions=permit_sasl_authenticated,reject
and changed the line from

To print the current working Directory i.e. pwd just type command like:
echo "the PWD is : ${pwd}"
To view the files just browse them from the command prompt (cmd
), eg.:
c:\>cd \Windows\assembly\GAC_32
c:\Windows\assembly\GAC_32> dir
To add and remove files from the GAC use the tool gacutil
git init
git remote add origin [email protected]:<user>/<repo>.git
git remote -v
git pull origin master

for(String c : keys)
{

for(Car c : values)
{
System.out.println(c.getDiscription());
}
/*keySet and the values methods serve as “views” into the Map.

for(Map.Entry<String, Car> e : cars)
{
System.out.println("Keys = " + e.getKey());
System.out.println("Values = " + e.getValue().getDiscription() + "\n");
}
To add to the other answers, a common use case I have found for setattr()
is when using configs. It is common to parse configs from a file (.ini file or whatever) into a dictionary. So you end up with something like:
configs = {'memory': 2.5, 'colour': 'red', 'charge': 0, ... }
If you want to then assign these configs to a class to be stored and passed around, you could do simple assignment:
MyClass.memory = configs['memory']
MyClass.colour = configs['colour']
MyClass.charge = configs['charge']
...
However, it is much easier and less verbose to loop over the configs, and setattr()
like so:
for name, val in configs.items():
setattr(MyClass, name, val)
As long as your dictionary keys have the proper names, this works very well and is nice and tidy.
*Note, the dict keys need to be strings as they will be the class object names.

Here's a one-line solution with mapfile:
$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "<regexp>")
Example:
$ arr=("Adam" "Bob" "Claire"$'\n'"Smith" "David" "Eve" "Fred")
$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"
Size: 6 Contents: Adam Bob Claire
Smith David Eve Fred
$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "^Claire\nSmith$")
$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"
Size: 5 Contents: Adam Bob David Eve Fred
This method allows for great flexibility by modifying/exchanging the grep command and doesn't leave any empty strings in the array.
I have been busy using different posts and methods for two days trying to figure it out. I urge anyone to START by looking at the post by Eggs, and mess around with the codepen he and others have built.
This has been the only solution to work properly for me that I have found. I recommend his answer as a solution/ a good starting point at minimum for those of us still figuring out this problem in our own web applications.
I haven't gotten enough reputation yet to comment on his post, otherwise I would. I can't even vote on it yet or I would do that too.
This is the actual code I used:
html::before {
content: ' ';
display: block;
background-image: url('path-to-your-image');
background-position: bottom left;
/*For my instance this is how I have built my bg image. Indexes off the
bottom left for consistency*/
background-size: cover;
top: 0;
bottom: 0;
left: 0;
right: 0;
position: fixed;
z-index: -10;
/*I haven't tested my full app functionality after changing the z-index, but everything appears to work flawlessly right now.*/
}
I tried everything with his original code. When I had
background-position: center;
chrome (on latest android update as of 1/8/18) would lag with updating the image's position, so when scrolling through the website there would be a patch of color where my navbar/URL bar of the browser was. Then it would disappear after the browser recalculated the image center(is what I assume was happening).
So, I recommend making an image around your footer or header like I did, and setting either top left/right or bottom left/right for your position.
In summary, THIS WORKS for me. So try it out if you're reading down this far and nothing has worked yet. Though you should've already hit the original post by now.
Thank you Eggs, and the other fellows you collaborated with on your Codepen.
Just as another alternative you could use HASHBYTES, something like this:
SELECT *
FROM a_table
WHERE HASHBYTES('sha1', attribute) = HASHBYTES('sha1', 'k')
l=[['A', 1], ['B', 2], ['C', 3]]
d={}
for i,j in l:
d.setdefault(i,j)
print(d)
write code in body tag like this
<body style="background-image: url('Image URL');" >
</body>
You can generalize @Nithin's answer to work directly with DRF's existing serializer system by generating a parser class to parse specific fields which are then fed directly into the standard DRF serializers:
from django.http import QueryDict
import json
from rest_framework import parsers
def gen_MultipartJsonParser(json_fields):
class MultipartJsonParser(parsers.MultiPartParser):
def parse(self, stream, media_type=None, parser_context=None):
result = super().parse(
stream,
media_type=media_type,
parser_context=parser_context
)
data = {}
# find the data field and parse it
qdict = QueryDict('', mutable=True)
for json_field in json_fields:
json_data = result.data.get(json_field, None)
if not json_data:
continue
data = json.loads(json_data)
if type(data) == list:
for d in data:
qdict.update({json_field: d})
else:
qdict.update({json_field: data})
return parsers.DataAndFiles(qdict, result.files)
return MultipartJsonParser
This is used like:
class MyFileViewSet(ModelViewSet):
parser_classes = [gen_MultipartJsonParser(['tags', 'permissions'])]
# ^^^^^^^^^^^^^^^^^^^
# Fields that need to be further JSON parsed
....
Here is an example Dockerfile leveraging several clever techniques to all you to run a full conda environment for every RUN
stanza. You can use a similar approach to execute any arbitrary prep in a script file.
Note: there is a lot of nuance when it comes to login/interactive vs nonlogin/noninteractive shells, signals, exec
, the way multiple args are handled, quoting, how CMD and ENTRYPOINT interact, and a million other things, so don't be discouraged if when hacking around with these things, stuff goes sideways. I've spent many frustrating hours digging through all manner of literature and I still don't quite get how it all clicks.

Simple solution not sure if this has been suggested or not. This also may not work for some things. That being said this is the simple solution below.
new SelectListItem { Value = "1", Text = "Waiting Invoices", Selected = true}
List<SelectListItem> InvoiceStatusDD = new List<SelectListItem>();
InvoiceStatusDD.Add(new SelectListItem { Value = "0", Text = "All Invoices" });
InvoiceStatusDD.Add(new SelectListItem { Value = "1", Text = "Waiting Invoices", Selected = true});
InvoiceStatusDD.Add(new SelectListItem { Value = "7", Text = "Client Approved Invoices" });
@Html.DropDownList("InvoiceStatus", InvoiceStatusDD)
You can also do something like this for a database driven select list. you will need to set selected in your controller
@Html.DropDownList("ApprovalProfile", (IEnumerable<SelectListItem>)ViewData["ApprovalProfiles"], "All Employees")
Something like this but better solutions exist this is just one method.
foreach (CountryModel item in CountryModel.GetCountryList())
{
if (item.CountryPhoneCode.Trim() != "974")
{
countries.Add(new SelectListItem { Text = item.CountryName + " +(" + item.CountryPhoneCode + ")", Value = item.CountryPhoneCode });
}
else {
countries.Add(new SelectListItem { Text = item.CountryName + " +(" + item.CountryPhoneCode + ")", Value = item.CountryPhoneCode,Selected=true });
}
}

I know this answer doesn't really match "with no extraneous information.", but I still think this list is more useful then just the filenames.
if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then

else

The above logic should be what you are looking for.
To reverse
byte[] bytemsg=msg.getBytes();
you can use
String text = new String(bytemsg);
using a BigInteger just complicates things, in fact it not clear why you want a byte[]. What are planing to do with the BigInteger or byte[]? What is the point?
I think that your problem is actually with not correctly indenting init function.It should be like this
class MyClass():
def __init__(self, filename):
pass
def parse_file():
pass
You need to type result
to an array of string const result: string[] = [];
.
Much simpler to understand approach:
dict = { 'a':302, 'e':53, 'g':302, 'h':100 }
max_value_keys = [key for key in dict.keys() if dict[key] == max(dict.values())]
print(max_value_keys) # prints a list of keys with max value
Output: ['a', 'g']
Now you can choose only one key:
maximum = dict[max_value_keys[0]]
You may do the following:
git -m master master-old #rename current master
git checkout -b master #create a new branch master
git push -f origin master #force push to master
But force pushing is a bad idea if other people are sharing this repository. Force push will cause their revision history to conflict with the new one.
This works good

I noticed in the Android source that almost every operation forces the Bundle to unparcel its data. So if (like me) you need to do this frequently for debugging purposes, the below is very quick to type:
Bundle extras = getIntent().getExtras();
extras.isEmpty(); // unparcel
System.out.println(extras);
There is an important bit that is not mentioned in the article to which you linked and that is flex-basis
. By default flex-basis
is auto
.
From the spec:
If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)
Each flex item has a flex-basis
which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow
) among the items. With auto
, that basis is the contents size (or defined size with width
, etc.). As a result, items with bigger text within are being given more space overall in your example.
If you want your elements to be completely even, you can set flex-basis: 0
. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow
.
li {
flex-grow: 1;
flex-basis: 0;
/* ... */
}
This diagram from the spec does a pretty good job of illustrating the point.
And here is a working example with your fiddle.
The generic method for this is fairly simple:
public static String convertSecondsToHMmSs(long seconds) {
long s = seconds % 60;
long m = (seconds / 60) % 60;
long h = (seconds / (60 * 60)) % 24;
return String.format("%d:%02d:%02d", h,m,s);
}
I have met the same problem. My project is running on the local server. I checked my php code.
$db = mysqli_connect('localhost', 'root', 'root', 'smart');
I use localhost
to connect to my local database. That maybe the cause of the problem which you're describing. You can modify your HOSTS
file. Add the line
127.0.0.1 localhost
.
You can define foreign key by:
public class Parent
{
public int Id { get; set; }
public virtual ICollection<Child> Childs { get; set; }
}
public class Child
{
public int Id { get; set; }
// This will be recognized as FK by NavigationPropertyNameForeignKeyDiscoveryConvention
public int ParentId { get; set; }
public virtual Parent Parent { get; set; }
}
Now ParentId is foreign key property and defines required relation between child and existing parent. Saving the child without exsiting parent will throw exception.
If your FK property name doesn't consists of the navigation property name and parent PK name you must either use ForeignKeyAttribute data annotation or fluent API to map the relation
Data annotation:
// The name of related navigation property
[ForeignKey("Parent")]
public int ParentId { get; set; }
Fluent API:
modelBuilder.Entity<Child>()
.HasRequired(c => c.Parent)
.WithMany(p => p.Childs)
.HasForeignKey(c => c.ParentId);
Other types of constraints can be enforced by data annotations and model validation.
Edit:
You will get an exception if you don't set ParentId
. It is required property (not nullable). If you just don't set it it will most probably try to send default value to the database. Default value is 0 so if you don't have customer with Id = 0 you will get an exception.
In my Notepad++ 7.2.2
, the Preferences
section it's a bit different.
The option is located at: Settings

I prefer to use border-spacing
as it allows more flexibility. For instance, you could do
table {
border-spacing: 0 2px;
}
Which would only collapse the vertical borders and leave the horizontal ones in tact, which is what it sounds like the OP was actually looking for.
Note that border-spacing: 0
is not the same as border-collapse: collapse
. You will need to use the latter if you want to add your own border to a tr
as seen here.
You can use Gson
.
Step 1
Add compile
compile 'com.google.code.gson:gson:2.8.2'
Step 2
Convert json to Kotlin Bean
(use JsonToKotlinClass)
Like this
Json
data
{
"timestamp": "2018-02-13 15:45:45",
"code": "OK",
"message": "user info",
"path": "/user/info",
"data": {
"userId": 8,
"avatar": "/uploads/image/20180115/1516009286213053126.jpeg",
"nickname": "",
"gender": 0,
"birthday": 1525968000000,
"age": 0,
"province": "",
"city": "",
"district": "",
"workStatus": "Student",
"userType": 0
},
"errorDetail": null
}
Kotlin Bean
class MineUserEntity {
data class MineUserInfo(
val timestamp: String,
val code: String,
val message: String,
val path: String,
val data: Data,
val errorDetail: Any
)
data class Data(
val userId: Int,
val avatar: String,
val nickname: String,
val gender: Int,
val birthday: Long,
val age: Int,
val province: String,
val city: String,
val district: String,
val workStatus: String,
val userType: Int
)
}
Step 3
Use Gson
var gson = Gson()
var mMineUserEntity = gson?.fromJson(response, MineUserEntity.MineUserInfo::class.java)
Restarting the device works for me. Using adb install can get the apk installed, but it's annoying to use it everytime you launch the app when debugging within eclipse.
You don't need to pass this
, there already is the event
object passed by default automatically, which contains event.target
which has the object it's coming from. You can lighten your syntax:
This:
<p onclick="doSomething()">
Will work with this:
function doSomething(){
console.log(event);
console.log(event.target);
}
You don't need to instantiate the event
object, it's already there. Try it out. And event.target
will contain the entire object calling it, which you were referencing as "this" before.
Now if you dynamically trigger doSomething() from somewhere in your code, you will notice that event
is undefined. This is because it wasn't triggered from an event of clicking. So if you still want to artificially trigger the event, simply use dispatchEvent
:
document.getElementById('element').dispatchEvent(new CustomEvent("click", {'bubbles': true}));
Then doSomething()
will see event
and event.target
as per usual!
No need to pass this
everywhere, and you can keep your function signatures free from wiring information and simplify things.
No. It's automatically called.
json = " { \"success\" : false, \"errors\": { \"text\" : \"??????!\" } }";
return new MemoryStream(Encoding.UTF8.GetBytes(json));
git rebase -i HEAD~<quantity of your commits>
(i.e. git rebase -i HEAD~5
)txt
file change pick
keyword to squash
for all commits, except first commit (which is on the top). For top one change it to reword
(which means you will provide a new comment for this commit in the next step) and click SAVE! If in vim, press esc
then save by entering wq!
and press enter.Done
compile
is a configuration
that is usually introduced by a plugin (most likely the java plugin) Have a look at the gradle userguide for details about configurations. For now adding the java plugin on top of your build script should do the trick:
apply plugin:'java'
Reverse a String without even using a new string. Lets say
String input = "Mark Henry";
//Just to convert into char array. One can simply take input in char array.
Char[] array = input.toCharArray(input);
int a = input.length;
for(int i=0; i<(array.length/2 -1) ; i++)
{
array[i] = array[i] + array[a];
array[a] = array[i] - array[a];
array[i] = array[i] - array[a--];
}

asserts position at the end of the string
To print the columns with a specific string, you use the // search pattern. For example, if you are looking for second columns that contains abc:
awk '$2 ~ /abc/'
... and if you want to print only a particular column:
awk '$2 ~ /abc/ { print $3 }'
... and for a particular line number:
awk '$2 ~ /abc/ && FNR == 5 { print $3 }'
In this case you might want to use the functions np.hstack and np.vstack
arr = np.array([])
arr = np.hstack((arr, np.array([1,2,3])))
# arr is now [1,2,3]
arr = np.vstack((arr, np.array([4,5,6])))
# arr is now [[1,2,3],[4,5,6]]
You also can use the np.concatenate function.

With Exuberant ctags, you can create tag files with file information:
ctags --extra=+f -R *
Then, open file from VIM with
:tag filename
You can also use <tab>
to autocomplete file name.
This should work in your case without removing namespaces:
XmlNode idNode = myXmlDoc.GetElementsByTagName("id")[0];
Note: this answer applies only to Angular components and directives, NOT services.
I had this same issue when ngOnInit
(and other lifecycle hooks) were not firing for my components, and most searches led me here.
The issue is that I was using the arrow function syntax (=>
) like this:
class MyComponent implements OnInit {
// Bad: do not use arrow function
public ngOnInit = () => {
console.log("ngOnInit");
}
}
Apparently that does not work in Angular 6. Using non-arrow function syntax fixes the issue:
class MyComponent implements OnInit {
public ngOnInit() {
console.log("ngOnInit");
}
}
That is not how the TryGetValue
works. It returns true
or false
based on whether the key is found or not, and sets its out
parameter to the corresponding value if the key is there.
If you want to check if the key is there or not and do something when it's missing, you need something like this:
bool hasValue = Data_Array.TryGetValue("XML_File", out value);
if (hasValue) {
xmlfile = value;
} else {
// do something when the value is not there
}
Another option is to store the object in value as a string:
<select [ngModel]="selectedDevice | json" (ngModelChange)="onChange($event)">
<option [value]="i | json" *ngFor="let i of devices">{{i}}</option>
</select>
component:
onChange(val) {
this.selectedDevice = JSON.parse(val);
}
This was the only way I could get two way binding working to set the select value on page load. This was because my list that populates the select box was not the exact same object as my select was bound to and it needs to be the same object, not just same property values.
the only thing you can do is to change your signature to
public static <E> E[] appendToArray(E[] array, E item)
Important details:
Generic expressions preceding the return value always introduce (declare) a new generic type variable.
Additionally, type variables between types (ArrayUtils
) and static methods (appendToArray
) never interfere with each other.
So, what does this mean:
In my answer <E>
would hide the E
from ArrayUtils<E>
if the method wouldn't be static
. AND <E>
has nothing to do with the E
from ArrayUtils<E>
.
To reflect this fact better, a more correct answer would be:
public static <I> I[] appendToArray(I[] array, I item)
Use the user agent from $_SERVER['HTTP_USER_AGENT']
,
and for simple detection you can use this script:
<?php
//Detect special conditions devices
$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$Android = stripos($_SERVER['HTTP_USER_AGENT'],"Android");
$webOS = stripos($_SERVER['HTTP_USER_AGENT'],"webOS");
//do something with this information
if( $iPod || $iPhone ){
//browser reported as an iPhone/iPod touch -- do something here
}else if($iPad){
//browser reported as an iPad -- do something here
}else if($Android){
//browser reported as an Android device -- do something here
}else if($webOS){
//browser reported as a webOS device -- do something here
}
?>
If you want to know more details of the user device I recommended to use one of the following solutions: http://51degrees.mobi or http://deviceatlas.com
I had this issue, grid lines appeared to be missing on some cells.
Took me awhile to figure out that the color of those cells were white. I clicked format cell, pattern and then selected "no color" (instead of white) The the grid lines were visible again.
I hope this helps others as it took me a while to figure out why.
I know this is late but it might be of some use:
echo "<pre>";
print_r($array);
echo "</pre>";
In my case I just ignored the following in application.properties file:
# Hibernate
#spring.jpa.hibernate.ddl-auto=update
It works for me....
Just use CSS.
.myclass
{
text-transform:capitalize;
}
@Html.Partial("NameOfPartialView")
If you have the char array null terminated, you can assign the char array to the string:
char[] chArray = "some characters";
String String(chArray);
As for your loop code, it looks right, but I will try on my controller to see if I get the same problem.
Follow the Instructions from the Ruby Installer Developer Kit Wiki:
cd C:\Ruby193\DevKit
ruby dk.rb init
ruby dk.rb review
ruby dk.rb install
To return to the problem at hand, you should be able to install JSON (or otherwise test that your DevKit successfully installed) by running the following commands which will perform an install of the JSON gem and then use it:
gem install json --platform=ruby
ruby -rubygems -e "require 'json'; puts JSON.load('[42]').inspect"
First of all, regular expressions should not have surrounding quotes, so '/\s/g' should be /\s/g
In order to replace all non-alphanumerical characters with dashes, this should work (using your example code):
$("#Restaurant_Name").keyup(function(){
var Text = $(this).val();
Text = Text.toLowerCase();
Text = Text.replace(/[^a-zA-Z0-9]+/g,'-');
$("#Restaurant_Slug").val(Text);
});
That should do the trick...
Simple Solution
If you are working with pure html/js/css files.
Install this small server(link) app in chrome. Open the app and point the file location to your project directory.
Goto the url shown in the app.
Edit: Smarter solution using Gulp
Step 1: To install Gulp. Run following command in your terminal.
npm install gulp-cli -g
npm install gulp -D
Step 2: Inside your project directory create a file named gulpfile.js. Copy the following content inside it.
var gulp = require('gulp');
var bs = require('browser-sync').create();
gulp.task('serve', [], () => {
bs.init({
server: {
baseDir: "./",
},
port: 5000,
reloadOnRestart: true,
browser: "google chrome"
});
gulp.watch('./**/*', ['', bs.reload]);
});
Step 3: Install browser sync gulp plugin. Inside the same directory where gulpfile.js is present, run the following command
npm install browser-sync gulp --save-dev
Step 4: Start the server. Inside the same directory where gulpfile.js is present, run the following command
gulp serve
The recommended way to create random integers with NumPy these days is to use numpy.random.Generator.integers
. (documentation)
import numpy as np
import pandas as pd
rng = np.random.default_rng()
df = pd.DataFrame(rng.integers(0, 100, size=(100, 4)), columns=list('ABCD'))
df

0 58 96 82 24
1 21 3 35 36
2 67 79 22 78

4 73 6 70 96
... ... ... ... ...
95 76 32 28 51
96 33 68 54 77

As mentioned in the other answers, you don't need jQuery to do this; you can just use the standard properties.
However, it seems you don't seem to know the difference between window.location.replace(url)
and window.location = url
.
window.location.replace(url)
replaces the current location in the address bar by a new one. The page that was calling the function, won't be included in the browser history. Therefore, on the new location, clicking the back button in your browser would make you go back to the page you were viewing before you visited the document containing the redirecting JavaScript.window.location = url
redirects to the new location. On this new page, the back button in your browser would point to the original page containing the redirecting JavaScript.Of course, both have their use cases, but it seems to me like in this case you should stick with the latter.
P.S.: You probably forgot two slashes after http:
on line 2 of your JavaScript:
url = "http://abc.com/" + temp;
I found the new emulator Build.HARDWARE = "ranchu"
.
Reference:https://groups.google.com/forum/#!topic/android-emulator-dev/dltBnUW_HzU
And also I found the Android official way to check whether emulator or not.I think it's good reference for us.
Since Android API Level 23 [Android 6.0]
package com.android.internal.util;
/**
* @hide
*/
public class ScreenShapeHelper {
private static final boolean IS_EMULATOR = Build.HARDWARE.contains("goldfish");
}
We have ScreenShapeHelper.IS_EMULATOR
to check whether emulator.
Since Android API Level 24 [Android 7.0]
package android.os;
/**
* Information about the current build, extracted from system properties.
*/
public class Build {
/**
* Whether this build was for an emulator device.
* @hide
*/
public static final boolean IS_EMULATOR = getString("ro.kernel.qemu").equals("1");
}
We have Build.IS_EMULATOR
to check whether emulator.
The way the official to check whether emulator is not new,and also maybe not enough,the answers above also mentioned.
But this maybe show us that the official will provide the way of official to check whether emulator or not.
As using the above all ways mentioned,right now we can also use the two ways about to check whether emulator.
How to access the com.android.internal
package and @hide
and wait for the official open SDK.

Remove all white spaces and create an fixed-size or immutable List (See asList
API docs)
final String str = "dog, cat, bear, elephant, ..., giraffe";
List<String> list = Arrays.asList(str.replaceAll("\\s", "").split(","));
// result: [dog, cat, bear, elephant, ..., giraffe]
It is possible to also use replaceAll(\\s+", "")
but maximum efficiency depends on the use case. (see @GurselKoca answer to Removing whitespace from strings in Java)
Perhaps... If you happen to use the Publish Wizard (like I did) and select the "Precompile during publishing" checkbox (like I did) and see the same symptoms...
Yeah, I beat myself over the head, but after unchecking this box, a seemingly unrelated setting, all the symptoms described go away after redeploying.
Hopefully this fixes some folks.
Process text to and from Unicode at the I/O boundaries of your program using open
with the encoding
parameter. Make sure to use the (hopefully documented) encoding of the file being read. The default encoding varies by OS (specifically, locale.getpreferredencoding(False)
is the encoding used), so I recommend always explicitly using the encoding
parameter for portability and clarity (Python 3 syntax below):
with open(filename, 'r', encoding='utf8') as f:
text = f.read()
# process Unicode text
with open(filename, 'w', encoding='utf8') as f:
f.write(text)
If still using Python 2 or for Python 2/3 compatibility, the io
module implements open
with the same semantics as Python 3's open
and exists in both versions:
import io
with io.open(filename, 'r', encoding='utf8') as f:
text = f.read()
# process Unicode text
with io.open(filename, 'w', encoding='utf8') as f:
f.write(text)
You can use this example to handle your problem:
System.out.printf( "%-15s %15s %n", "name", "lastname");
System.out.printf( "%-15s %15s %n", "Bill", "Smith");
You can play with the "%" until you find the right alignment to satisfy your needs
@Arnon Rotem-Gal-Oz answer is right for the most part. But I would like to point out the difference between df['year']=df['year'].astype(int)
and df.year.astype(int)
. df.year.astype(int)
returns a view of the dataframe and doesn't not explicitly change the type, atleast in pandas 0.24.2. df['year']=df['year'].astype(int)
explicitly change the type because it's an assignment. I would argue that this is the safest way to permanently change the dtype of a column.
Example:
df = pd.DataFrame({'Weed': ['green crack', 'northern lights', 'girl scout
cookies'], 'Qty':[10,15,3]})
df.dtypes
Weed object, Qty int64
df['Qty'].astype(str)
df.dtypes
Weed object, Qty int64
Even setting the inplace arg to True doesn't help at times. I don't know why this happens though. In most cases inplace=True equals an explicit assignment.
df['Qty'].astype(str, inplace = True)
df.dtypes
Weed object, Qty int64
Now the assignment,
df['Qty'] = df['Qty'].astype(str)
df.dtypes
Weed object, Qty object

No. Any valid string is a valid key. It can even have "
as long as you escape it:
{"The \"meaning\" of life":42}
There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.
Change column position:
ALTER TABLE Employees
CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;
If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:
ALTER TABLE UserOrder
CHANGE order_id order_id INT(11) NOT NULL FIRST;
If you want this type of code to run in IE11 (which does not support much of ES6 at all), then you need to get a 3rd party promise library (like Bluebird), include that library and change your coding to use ES5 coding structures (no arrow functions, no let
, etc...) so you can live within the limits of what older browsers support.
Or, you can use a transpiler (like Babel) to convert your ES6 code to ES5 code that will work in older browsers.
Here's a version of your code written in ES5 syntax with the Bluebird promise library:
<script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/3.3.4/bluebird.min.js"></script>
<script>
'use strict';
var promise = new Promise(function(resolve) {
setTimeout(function() {
resolve("result");
}, 1000);
});
promise.then(function(result) {
alert("Fulfilled: " + result);
}, function(error) {
alert("Rejected: " + error);
});

One way I've found to do this is to create an img tag and set the src attribute to the file you are looking for. The onload or onerror of the img element will fire based on whether the file exists. You can't load any data using this method, but you can determine if a particular file exists or not.

This is better than getting from sys.columns
because it shows DATA_TYPE
directly.
You can do like this:
List<String> yourList = new ArrayList<String>();
Collections.sort(yourList, Collections.reverseOrder());
Collection has a default Comparator that can help you with that.
Also, if you want to use some Java 8 new features, you can do like that:
List<String> yourList = new ArrayList<String>();
yourList = yourList.stream().sorted(Collections.reverseOrder()).collect(Collectors.toList());

The fact that primitives are signed in Java is irrelevant to how they're represented in memory / transit - a byte is merely 8 bits and whether you interpret that as a signed range or not is up to you. There is no magic flag to say "this is signed" or "this is unsigned".
As primitives are signed the Java compiler will prevent you from assigning a value higher than +127 to a byte (or lower than -128). However, there's nothing to stop you downcasting an int (or short) in order to achieve this:
int i = 200; // 0000 0000 0000 0000 0000 0000 1100 1000 (200)
byte b = (byte) 200; // 1100 1000 (-56 by Java specification, 200 by convention)
/*
* Will print a negative int -56 because upcasting byte to int does
* so called "sign extension" which yields those bits:
* 1111 1111 1111 1111 1111 1111 1100 1000 (-56)
*

add this to your package.json file
scripts {
"dev": "nodemon --watch '**/*.ts' --exec 'ts-node' index.ts"
}
and to make this work you also need to install ts-node as dev-dependency
yarn add ts-node -D
run yarn dev
to start the dev server
" Hello " , " This " , "is ", "Sorting ", "Example"
First of all you provided spaces in " Hello "
and " This "
, spaces have a lower value than alphabetic characters in Unicode, so it gets printed first. (The rest of the characters were sorted alphabetically).
Now upper case letters have a lower value than lower case letter in Unicode, so "Example" and "Sorting" gets printed, then at last "is "
which has the highest value.
From the spec:
All characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark (U+0022), reverse solidus [backslash] (U+005C), and the control characters U+0000 to U+001F
Just because e.g. Bell (U+0007) doesn't have a single-character escape code does not mean that you don't need to escape it. Use the Unicode escape sequence \u0007
.
Probably the best solution is to look at the threeparttable/threeparttablex packages.

If you want to study code how to setup a "Baseline" web application with ViewModels I can advise to download this code on GitHub: https://github.com/ajsaulsberry/BlipAjax. I developed large enterprise applications. When you do this its problematic to setup a good architecture that handles all this "ViewModel" functionality. I think with BlipAjax you will have a very Good "baseline" to start with. Its just a simple website, but great in its simplicity. I like the way they used the English language to point at whats really needed in the application.
You could use complete unix paths like:
PATH=$PATH:/c/python26
git config --global merge.tool meld
git config --global mergetool.meld.path /c/Program files (x86)/meld/bin/meld
This is what is described in "How to get meld working with git on Windows"
Or you can adopt the wrapper approach described in "Use Meld with Git on Windows"
# set up Meld as the default gui diff tool
$ git config --global diff.guitool meld
# set the path to Meld
$ git config --global mergetool.meld.path C:/meld-1.6.0/Bin/meld.sh
With a script meld.sh
:
#!/bin/env bash
C:/Python27/pythonw.exe C:/meld-1.6.0/bin/meld $@
abergmeier mentions in the comments:
I had to do:
git config --global merge.tool meld
git config --global mergetool.meld.path /c/Program files (x86)/Meld/meld/meldc.exe
Note that meldc.exe was especially created to be invoked on Windows via console. Thus meld.exe will not work properly.
CenterOrbit mentions in the comments for Mac OS to install homebrew, and then:
brew cask install meld
git config --global merge.tool meld
git config --global diff.guitool meld
This happens because LatLngBounds()
does not take two arbitrary points as parameters, but SW and NE points
use the .extend()
method on an empty bounds object
var bounds = new google.maps.LatLngBounds();
bounds.extend(myPlace);
bounds.extend(Item_1);
map.fitBounds(bounds);

It sounds like you are going to be storing the value that input field contains after the form is submitted, which means you are using a scripting language. I would use it instead of JavaScript as most scripting languages have better time/date formatting options. In PHP you could do something like this:
<input id="date" name="date" value="<?php echo date("M j, Y - g:i"); ?>"/>
Which would fill the field with "Jun 16, 2009 - 8:58"
PEAR::Mail_Mime? Sure, PEAR dependency of (min) 2 files (just mail_mime itself if you edit it to remove the pear dependencies), but it works well. Additionally, most servers have PEAR installed to some extent, and in the best cases they have Pear/Mail and Pear/Mail_Mime. Something that cannot be said for most other libraries offering the same functionality.
You may also consider looking in to PHP's IMAP extension. It's a little more complicated, and requires more setup (not enabled or installed by default), but is must more efficient at compilng and sending messages to an IMAP capable server.
lots of methods available in php to read a file like exec, file_get_contents, curl and fopen but it depend on your requirement and file permission
Visit this file_get_contents vs cUrl
Basically file_get_contents for for you
$data = file_get_contents($file_url);
It looks like you want to convert the list to a list of numbers
>>> foo = ['-1.2', '0.0', '1']
>>> bar = map(float, foo)
>>> bar
[-1.2, 0.0, 1.0]
>>> min(bar)
-1.2
or if it really is strings you want, that you want to use min
's key
argument
>>> foo = ['-1.2', '0.0', '1']
>>> min(foo, key=float)
'-1.2'
Apparently, there's a lot of "dead wood" in the "build" directories of a project.
Under linux/unix, a simple way to get a clean, private backup is to use the "tar" command along with the "--exclude=String" option.
For example, to create an archive of all my apps while excluding the build directories, I have a script that creates the following 2 commands :
cd $HOME/android/Studio
tar cvf MyBackup-2017-07-13.tar Projects --exclude=build
You can either define the right default value into the model you want to edit with this form or you can specify an empty_data option so your code become:
$form = $this
->createFormBuilder($breed)
->add(
'species',
'entity',
array(
'class' => 'BFPEduBundle:Item',
'property' => 'name',
'empty_data' => 123,
'query_builder' => function(ItemRepository $er) {
return $er
->createQueryBuilder('i')
->where("i.type = 'species'")
->orderBy('i.name', 'ASC')
;
}
)
)
->add('breed', 'text', array('required'=>true))
->add('size', 'textarea', array('required' => false))
->getForm()
;
You can change style directly for scene using .root
class:
.root {
-fx-background-image: url("https://www.google.com/images/srpr/logo3w.png");
}
Add this to CSS and load it as "Uluk Biy" described in his answer.
2^31-1 bytes. So, a little less than 2^31-1 characters for varchar(max) and half that for nvarchar(max).
tar -cvzf destination_folder source_folder -X /home/folder/excludes.txt
-X indicates a file which contains a list of filenames which must be excluded from the backup. For Instance, you can specify *~ in this file to not include any filenames ending with ~ in the backup.

You're very close:
while IFS=$'\t' read -r -a myArray
do
echo "${myArray[0]}"
echo "${myArray[1]}"
echo "${myArray[2]}"
done < myfile
(The -r
tells read
that \
isn't special in the input data; the -a myArray
tells it to split the input-line into words and store the results in myArray
; and the IFS=$'\t'
tells it to use only tabs to split words, instead of the regular Bash default of also allowing spaces to split words as well. Note that this approach will treat one or more tabs as the delimiter, so if any field is blank, later fields will be "shifted" into earlier positions in the array. Is that O.K.?)
if you are using centOS or Red Hat, you should first update SElinux. Execute the following statement
ausearch -c 'sshd' --raw | audit2allow -M my-sshd
then you need to execute
semodule -i my-sshd.pp

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)
#include <iostream>
int main()
{
std::cout<<"Hello World!\n";
return 0;
}
C++ language has no such thing as typeof
. You must be looking at some compiler-specific extension. If you are talking about GCC's typeof
, then a similar feature is present in C++11 through the keyword decltype
. Again, C++ has no such typeof
keyword.
typeid
is a C++ language operator which returns type identification information at run time. It basically returns a type_info
object, which is equality-comparable with other type_info
objects.
Note, that the only defined property of the returned type_info
object has is its being equality- and non-equality-comparable, i.e. type_info
objects describing different types shall compare non-equal, while type_info
objects describing the same type have to compare equal. Everything else is implementation-defined. Methods that return various "names" are not guaranteed to return anything human-readable, and even not guaranteed to return anything at all.
Note also, that the above probably implies (although the standard doesn't seem to mention it explicitly) that consecutive applications of typeid
to the same type might return different type_info
objects (which, of course, still have to compare equal).
I had the same problem in windows The error was that I had installed several versions of PHP and the Environment Variables were routing to wrong Path of php see image example
I had the same problem,
Set all text/varchar collations in phpMyAdmin to utf-8 and in php files add this:
mysql_set_charset("utf8", $your_connection_name);
This solved it for me.
Just for the sake of completeness, here is a solution with lambda and method reference:
Description: The following method
String
with the pattern yyyy-MM-dd
into a Timestamp
, if a valid input is given,null
, if a null
value is given,DateTimeParseException
, if an invalid input is givenCode:
static Timestamp convertStringToTimestamp(String strDate) {
return Optional.ofNullable(strDate) // wrap the String into an Optional
.map(str -> LocalDate.parse(str).atStartOfDay()) // convert into a LocalDate and fix the hour:minute:sec to 00:00:00
.map(Timestamp::valueOf) // convert to Timestamp
.orElse(null); // if no value is present, return null
}
Validation:
This method can be tested with those unit tests:
(with Junit5 and Hamcrest)
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenValidInput() {
// given
String strDate = "2020-01-30";
// when
final Timestamp result = convertStringToTimestamp(strDate);
// then
final LocalDateTime dateTime = LocalDateTime.ofInstant(result.toInstant(), ZoneId.systemDefault());
assertThat(dateTime.getYear(), is(2020));
assertThat(dateTime.getMonthValue(), is(1));
assertThat(dateTime.getDayOfMonth(), is(30));
}
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenInvalidInput() {
// given
String strDate = "7770-91-30";
// when, then
assertThrows(DateTimeParseException.class, () -> convertStringToTimestamp(strDate));
}
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenNullInput() {
// when
final Timestamp result = convertStringToTimestamp(null);
// then
assertThat(result, is(nullValue()));
}
Usually, the string to parse comes with another format. A way to deal with it is to use a formatter to convert it to another format. Here is an example:
Input: 20200130 11:30
Pattern: yyyyMMdd HH:mm
Output: Timestamp of this input
Code:
static Timestamp convertStringToTimestamp(String strDate) {
final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm");
return Optional.ofNullable(strDate) //
.map(str -> LocalDateTime.parse(str, formatter))
.map(Timestamp::valueOf) //
.orElse(null);
}
Test:
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenValidInput() {
// given
String strDate = "20200130 11:30";
// when
final Timestamp result = convertStringToTimestamp(strDate);
// then
final LocalDateTime dateTime = LocalDateTime.ofInstant(result.toInstant(), ZoneId.systemDefault());
assertThat(dateTime.getYear(), is(2020));
assertThat(dateTime.getMonthValue(), is(1));
assertThat(dateTime.getDayOfMonth(), is(30));
assertThat(dateTime.getHour(), is(11));
assertThat(dateTime.getMinute(), is(30));
}
like:
$('#Create .myClass, #Edit .myClass').plugin({
options: here
});
You can specify any number of selectors to combine into a single result. This multiple expression combinator is an efficient way to select disparate elements. The order of the DOM elements in the returned jQuery object may not be identical, as they will be in document order. An alternative to this combinator is the .add() method.
All answers above are incomplete, the problem here lies in linker ld
rather than compiler collect2: ld returned 1 exit status
. When you are compiling your fib.c
to object:
$ gcc -c fib.c
$ nm fib.o
0000000000000028 T fibo
U floor
U _GLOBAL_OFFSET_TABLE_
0000000000000000 T main
U pow
U printf
Where nm
lists symbols from object file. You can see that this was compiled without an error, but pow
, floor
, and printf
functions have undefined references, now if I will try to link this to executable:
$ gcc fib.o
fib.o: In function `fibo':
fib.c:(.text+0x57): undefined reference to `pow'
fib.c:(.text+0x84): undefined reference to `floor'
collect2: error: ld returned 1 exit status
Im getting similar output you get. To solve that, I need to tell linker where to look for references to pow
, and floor
, for this purpose I will use linker -l
flag with m
which comes from libm.so
library.
$ gcc fib.o -lm
$ nm a.out

You can now see, functions pow
, floor
are linked to GLIBC_2.2.5
.
Parameters order is important too, unless your system is configured to use shared librares by default, my system is not, so when I issue:
$ gcc -lm fib.o
fib.o: In function `fibo':
fib.c:(.text+0x57): undefined reference to `pow'
fib.c:(.text+0x84): undefined reference to `floor'
collect2: error: ld returned 1 exit status
Note -lm
flag before object file. So in conclusion, add -lm
flag after all other flags, and parameters, to be sure.
Use a library to (a) read the sound file(s) and (b) play them back. (I'd recommend trying both yourself at some point in your spare time, but...)

I know this is an old question, but I think this is the definitive answer.
listViewRamos.Items[i].Focused = true;
listViewRamos.Items[i].Selected = true;
listViewRemos.Items[i].EnsureVisible();
If there is a chance the control does not have the focus but you want to force the focus to the control, then you can add the following line.
listViewRamos.Select();
Why Microsoft didn't just add a SelectItem()
method that does all this for you is beyond me.
UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

Sets the timeout to 5 minutes instead of the default 110 seconds (what an odd default?)

If security is important to you then opening the file for writing and closing it again will not be enough. At least some of the information will still be on the storage device and could be found, for example, by using a disc recovery utility.
Suppose, for example, the file you're erasing contains production passwords and needs to be deleted immediately after the present operation is complete.
Zero-filling the file once you've finished using it helps ensure the sensitive information is destroyed.
On a recent project we used the following code, which works well for small text files. It overwrites the existing contents with lines of zeros.
import os
def destroy_password_file(password_filename):
with open(password_filename) as password_file:
text = password_file.read()
lentext = len(text)
zero_fill_line_length = 40
zero_fill = ['0' * zero_fill_line_length
for _
in range(lentext // zero_fill_line_length + 1)]
zero_fill = os.linesep.join(zero_fill)
with open(password_filename, 'w') as password_file:
password_file.write(zero_fill)
Note that zero-filling will not guarantee your security. If you're really concerned, you'd be best to zero-fill and use a specialist utility like File Shredder or CCleaner to wipe clean the 'empty' space on your drive.
Why Server.Transfer
? Response.Redirect(Request.RawUrl)
would get you what you need.
Another way is to call an external process such as curl.exe. Curl by default displays a progress bar, average download speed, time left, and more all formatted neatly in a table. Put curl.exe in the same directory as your script
from subprocess import call
url = ""

I found that along with setting the -p port values, Docker for Windows uses vpnkit and inbound traffic for it was disabled by default on my host machine's firewall. After enabling the inbound TCP rules for vpnkit I was able to access my containers from other machines on the local network.
There are two ways:
The best way is to remove the <p>
altogether. It is acting according to specification when it adds space.
Alternately, use CSS to style the <p>
. Something like:
ul li p {
padding: 0;
margin: 0;
display: inline;
}
All answers here provide good and working code. But someone would be dissatisfied that they all use ContentType
as return type and not JsonResult
.
Unfortunately JsonResult
is using JavaScriptSerializer
without option to disable it. The best way to get around this is to inherit JsonResult
.
I copied most of the code from original JsonResult
and created JsonStringResult
class that returns passed string as application/json
. Code for this class is below
public class JsonStringResult : JsonResult
{
public JsonStringResult(string data)
{
JsonRequestBehavior = JsonRequestBehavior.DenyGet;
Data = data;
}
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
if (JsonRequestBehavior == JsonRequestBehavior.DenyGet &&
String.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
{
throw new InvalidOperationException("Get request is not allowed!");
}
HttpResponseBase response = context.HttpContext.Response;
if (!String.IsNullOrEmpty(ContentType))
{
response.ContentType = ContentType;
}
else
{
response.ContentType = "application/json";
}
if (ContentEncoding != null)
{
response.ContentEncoding = ContentEncoding;
}
if (Data != null)
{
response.Write(Data);
}
}
}
Example usage:
var json = JsonConvert.SerializeObject(data);
return new JsonStringResult(json);
I'd personally suggest using a different unit of measurement than px
. I don't think that pixels have much relevance in terms of print; ideally you'd use:
I'm sure there are others, and one excellent article about print-css can be found here: Going to Print, by Eric Meyer.
The answers here work for just 2 cells, but as soon as those columns have more in them it can lead to a bit more complexity. I think I've found a generalized solution for any number of cells in multiple columns.
#Goals Get a vertical sequence of tags on mobile to arrange themselves in whatever order the design calls for on tablet/desktop. In this concrete example, one tag must enter flow earlier than it normally would, and another later than it normally would.
##Mobile
[1 headline]
[2 image]
[3 qty]
[4 caption]
[5 desc]
##Tablet+
[2 image ][1 headline]
[ ][3 qty ]
[ ][5 desc ]
[4 caption][ ]
[ ][ ]
So headline needs to shuffle right on tablet+, and technically, so does desc - it sits above the caption tag that precedes it on mobile. You'll see in a moment 4 caption is in trouble too.
Let's assume every cell could vary in height, and needs to be flush top-to-bottom with its next cell (ruling out weak tricks like a table).
As with all Bootstrap Grid problems step 1 is to realize the HTML has to be in mobile-order, 1 2 3 4 5, on the page. Then, determine how to get tablet/desktop to reorder itself in this way - ideally without Javascript.
The solution to get 1 headline
and 3 qty
to sit to the right not the left is to simply set them both pull-right
. This applies CSS float: right
, meaning they find the first open space they'll fit to the right. You can think of the browser's CSS processor working in the following order: 1 fits in to the right top corner. 2 is next and is regular (float: left
), so it goes to top-left corner. Then 3, which is float: right
so it leaps over underneath 1.
But this solution wasn't enough for 4 caption
; because the right 2 cells are so short 2 image
on the left tends to be longer than the both of them combined. Bootstrap Grid is a glorified float hack, meaning 4 caption
is float: left
. With 2 image
occupying so much room on the left, 4 caption
attempts to fit in the next available space - often the right column, not the left where we wanted it.
The solution here (and more generally for any issue like this) was to add a hack tag, hidden on mobile, that exists on tablet+ to push caption out, that then gets covered up by a negative margin - like this:
[2 image ][1 headline]
[ ][3 qty ]
[ ][4 hack ]
[5 caption][6 desc ^^^]
[ ][ ]
http://jsfiddle.net/b9chris/52VtD/16633/
HTML:
<div id=headline class="col-xs-12 col-sm-6 pull-right">Product Headline</div>
<div id=image class="col-xs-12 col-sm-6">Product Image</div>
<div id=qty class="col-xs-12 col-sm-6 pull-right">Qty, Add to cart</div>
<div id=hack class="hidden-xs col-sm-6">Hack</div>
<div id=caption class="col-xs-12 col-sm-6">Product image caption</div>
<div id=desc class="col-xs-12 col-sm-6 pull-right">Product description</div>
CSS:
#hack { height: 50px; }
@media (min-width: @screen-sm) {
#desc { margin-top: -50px; }
}
So, the generalized solution here is to add hack tags that can disappear on mobile. On tablet+ the hack tags allow displayed tags to appear earlier or later in the flow, then get pulled up or down to cover up those hack tags.
Note: I've used fixed heights for the sake of the simple example in the linked jsfiddle, but the actual site content I was working on varies in height in all 5 tags. It renders properly with relatively large variance in tag heights, especially image and desc.
Note 2: Depending on your layout, you may have a consistent enough column order on tablet+ (or larger resolutions), that you can avoid use of hack tags, using margin-bottom
instead, like so:
Note 3: This uses Bootstrap 3. Bootstrap 4 uses a different grid set, and won't work with these examples.

just use a Button with android:drawableRight properties like this:
<Button android:id="@+id/btnNovaCompra" android:layout_width="wrap_content"
android:text="@string/btn_novaCompra"
android:gravity="center"
android:drawableRight="@drawable/shoppingcart"
android:layout_height="wrap_content"/>
Close()
- It is used to close the browser or page currently which is having the focus.
Quit()
- It is used to shut down the web driver instance or destroy the web driver instance(Close all the windows).
Dispose()
- I am not aware of this method.
SELECT * FROM `permlog` as one
RIGHT JOIN (SELECT MAX(id) as max_id FROM `permlog`) as two
ON one.id = two.max_id
How about this:
from pandas import *
idx = Int64Index([171, 174, 173])
df = DataFrame(index = idx, data =([1,2,3]))
print df
It gives me:
0
171 1
174 2
173 3
Is this what you are looking for?
In XML you can add this line to the EditText
View
where 140 is the maximum number of characters:
android:maxLength="140"
define
I use for global constants.
const
I use for class constants.
You cannot define
into class scope, and with const
you can. Needless to say, you cannot use const
outside class scope.
Also, with const
, it actually becomes a member of the class, and with define
, it will be pushed to global scope.
I had this problem once for no apparent reason. It was happenning locally whilst I was running through the aspnet development server. It had been working and I reverted everything to a state where it had previously been working and still it didn't work. I looked in the chrome debugger and the jquery-1.7.1.min.js had loaded without any problems. It was all very confusing. I still don't know what the problem was but closing the browser, closing the development server and then trying again sorted it out.
You can use the modify the code below to write your file from whatever class or function is handling the text. One wonders though why the world needs a new text editor...
import java.io.*;
public class Main {
public static void main(String[] args) {
try {
String str = "SomeMoreTextIsHere";
File newTextFile = new File("C:/thetextfile.txt");
FileWriter fw = new FileWriter(newTextFile);
fw.write(str);
fw.close();
} catch (IOException iox) {
//do stuff with exception
iox.printStackTrace();
}
}
}
FWIW, I got this error when I was implementing core data in to an existing project. It turned out I forgot to link CoreData.h to my project. I had already added the CoreData framework to my project but solved the issue by linking to the framework in my pre-compiled header just like Apple's templates do:
#import <Availability.h>
#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>
#endif
You don't need the QCoreApplication
at all, just include your Qt objects as you would other objects, for example:
#include <QtCore>
int main()
{
QVector<int> a; // Qt object
for (int i=0; i<10; i++)
{
a.append(i);
}
/* manipulate a here */
return 0;
}
Why are you using a macro? Excel has Password Protection built-in. When you select File/Save As... there should be a Tools button by the Save button, click it then "General Options" where you can enter a "Password to Open" and a "Password to Modify".
If you want to read any created function, this how we do it:
<input type="button" value="sports" onClick="window.open('<?php sports();?>', '_self');">

subprocess.call(" python script2.py 1", shell=True)
Like others have said, it's not possible with just JavaScript due to the security model of such.
If you are able to, I'd recommend one of the below solutions..both of which use a flash component for the client side validations; however, are wired up using Javascript/jQuery. Both work very well and can be used with any server-side tech.
If you are looking for a way to pass additional URL parameters (not controller, action, id, etc), here's a robust method for doing so:
object_path(@object, params: request.query_parameters)
That will pass along utm parameters or any other additional params you don't want to lose.
Some awk
version.
awk '/19:55/{c=5} c-->0'

If c

Make the submit button the main image you are using. So the form tags would come first then submit button which is your only image so the image is your clickable image form. Then just make sure to put whatever you are passing before the submit button code.
If you are using ASP.NET MVC Core 3 or newer, IHostingEnvironment

If you do what it suggests and recompile with the "-Xlint:unchecked" switch, it will give you more detailed information.
As well as the use of raw types (as described by the other answers), an unchecked cast can also cause the warning.
Once you've compiled with -Xlint, you should be able to rework your code to avoid the warning. This is not always possible, particularly if you are integrating with legacy code that cannot be changed. In this situation, you may decide to suppress the warning in places where you know that the code is correct:
@SuppressWarnings("unchecked")
public void myMethod()
{
//...
}
use this code in manifest.xml
<uses-sdk
android:minSdkVersion="16"
android:maxSdkVersion="17"
tools:overrideLibrary="x"/>
You can force update your master
branch as follows:
git checkout upstreambranch
git branch master upstreambranch -f
git checkout master
git push origin master -f
For the ones who have problem to merge into main
branch (Which is the new default one in Github) you can use the following:
git checkout master
git branch main master -f
git checkout main
git push origin main -f
The following command will force both branches to have the same history:
git branch [Branch1] [Branch2] -f
I found it easier to just take over the template from Bootstrap-ui. I have left the commented HTML still in-place to show what I changed.
Overwrite their default template:
<script type="text/ng-template" id="myDlgTemplateWrapper.html">
<div tabindex="-1" role="dialog" class="modal fade" ng-class="{in: animate}"
ng-style="{'z-index': 1050 + index*10, display: 'block'}" ng-click="close($event)">
<!-- <div class="modal-dialog"
ng-class="{'modal-sm': size == 'sm', 'modal-lg': size == 'lg'}"
>
<div class="modal-content" modal-transclude></div>
</div>-->
<div modal-transclude>
<!-- Your content goes here -->
</div>
</div>
</script>
Modify your dialog template (note the wrapper DIVs containing "modal-dialog" class and "modal-content" class):
<script type="text/ng-template" id="myModalContent.html">
<div class="modal-dialog {{extraDlgClass}}"
style="width: {{width}}; max-width: {{maxWidth}}; min-width: {{minWidth}}; ">
<div class="modal-content">
<div class="modal-header bg-primary">
<h3>I am a more flexible modal!</h3>
</div>
<div class="modal-body"
style="min-height: {{minHeight}}; height: {{height}}; max-height {{maxHeight}}; ">
<p>Make me any size you want</p>
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn btn-warning" ng-click="cancel()">Cancel</button>
</div>
</div>
</div>
</script>
And then call the modal with whatever CSS class or style parameters you wish to change (assuming you have already defined "app" somewhere else):
<script type="text/javascript">
app.controller("myTest", ["$scope", "$modal", function ($scope, $modal)
{
// Adjust these with your parameters as needed
$scope.extraDlgClass = undefined;
$scope.width = "70%";
$scope.height = "200px";
$scope.maxWidth = undefined;
$scope.maxHeight = undefined;
$scope.minWidth = undefined;
$scope.minHeight = undefined;
$scope.open = function ()
{
$scope.modalInstance = $modal.open(
{
backdrop: 'static',
keyboard: false,
modalFade: true,
templateUrl: "myModalContent.html",
windowTemplateUrl: "myDlgTemplateWrapper.html",
scope: $scope,
//size: size, - overwritten by the extraDlgClass below (use 'modal-lg' or 'modal-sm' if desired)
extraDlgClass: $scope.extraDlgClass,
width: $scope.width,
height: $scope.height,
maxWidth: $scope.maxWidth,
maxHeight: $scope.maxHeight,
minWidth: $scope.minWidth,
minHeight: $scope.minHeight
});
$scope.modalInstance.result.then(function ()
{
console.log('Modal closed at: ' + new Date());
},
function ()
{
console.log('Modal dismissed at: ' + new Date());
});
};
$scope.ok = function ($event)
{
if ($event)
$event.preventDefault();
$scope.modalInstance.close("OK");
};
$scope.cancel = function ($event)
{
if ($event)
$event.preventDefault();
$scope.modalInstance.dismiss('cancel');
};
$scope.openFlexModal = function ()
{
$scope.open();
}
}]);
</script>
Add an "open" button and fire away.
<button ng-controller="myTest" class="btn btn-default" type="button" ng-click="openFlexModal();">Open Flex Modal!</button>
Now you can add whatever extra class you want, or simply change width/height sizes as necessary.
I further enclosed it within a wrapper directive, which is should be trivial from this point forward.
Cheers.
Runtime is somewhat opposite to design-time and compile-time/link-time. Historically it comes from slow mainframe environment where machine-time was expensive.
there are two properties of urllib.URLopener()
namely:
addheaders = [('User-Agent', 'Python-urllib/1.17'), ('Accept', '*/*')]
and
version = 'Python-urllib/1.17'
.
To fool the website you need to changes both of these values to an accepted User-Agent. for e.g.
Chrome browser : 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.149 Safari/537.36'
Google bot : 'Googlebot/2.1'
like this
import urllib
page_extractor=urllib.URLopener()
page_extractor.addheaders = [('User-Agent', 'Googlebot/2.1'), ('Accept', '*/*')]
page_extractor.version = 'Googlebot/2.1'
page_extractor.retrieve(<url>, <file_path>)
changing just one property does not work because the website marks it as a suspicious request.
For further reference, a one liner that can be applied in, for example, !#/bin/sh
scripts.
EPOCH="`perl -e 'use Time::Local; print timelocal('${SEC}','${MIN}','${HOUR}','${DAY}','${MONTH}','${YEAR}'),\"\n\";'`"
Just remember to avoid octal values!
>>> import subprocess
>>> subprocess.call('echo $HOME')
Traceback (most recent call last):
...
OSError: [Errno 2] No such file or directory
>>>
>>> subprocess.call('echo $HOME', shell=True)
/user/khong
0
Setting the shell argument to a true value causes subprocess to spawn an intermediate shell process, and tell it to run the command. In other words, using an intermediate shell means that variables, glob patterns, and other special shell features in the command string are processed before the command is run. Here, in the example, $HOME was processed before the echo command. Actually, this is the case of command with shell expansion while the command ls -l considered as a simple command.

In a servlet based artifact, such as @WebServlet
, @WebFilter
and @WebListener
, you can grab a "plain vanilla" JSF @ManagedBean @RequestScoped
by:
Bean bean = (Bean) request.getAttribute("beanName");
and @ManagedBean @SessionScoped
by:
Bean bean = (Bean) request.getSession().getAttribute("beanName");
and @ManagedBean @ApplicationScoped
by:
Bean bean = (Bean) getServletContext().getAttribute("beanName");
Note that this prerequires that the bean is already autocreated by JSF beforehand. Else these will return null
. You'd then need to manually create the bean and use setAttribute("beanName", bean)
.
If you're able to use CDI @Named
instead of the since JSF 2.3 deprecated @ManagedBean
, then it's even more easy, particularly because you don't anymore need to manually create the beans:
@Inject
private Bean bean;
Note that this won't work when you're using @Named @ViewScoped
because the bean can only be identified by JSF view state and that's only available when the FacesServlet
has been invoked. So in a filter which runs before that, accessing an @Inject
ed @ViewScoped
will always throw ContextNotActiveException
.
Only when you're inside @ManagedBean
, then you can use @ManagedProperty
:
@ManagedProperty("#{bean}")
private Bean bean;
Note that this doesn't work inside a @Named
or @WebServlet
or any other artifact. It really works inside @ManagedBean
only.
If you're not inside a @ManagedBean
, but the FacesContext
is readily available (i.e. FacesContext#getCurrentInstance()
doesn't return null
), you can also use Application#evaluateExpressionGet()
:
FacesContext context = FacesContext.getCurrentInstance();
Bean bean = context.getApplication().evaluateExpressionGet(context, "#{beanName}", Bean.class);
which can be convenienced as follows:
@SuppressWarnings("unchecked")
public static <T> T findBean(String beanName) {
FacesContext context = FacesContext.getCurrentInstance();
return (T) context.getApplication().evaluateExpressionGet(context, "#{" + beanName + "}", Object.class);
}
and can be used as follows:
Bean bean = findBean("bean");

In summary, two ways were introduced
1) using order by DBMS_RANDOM.VALUE clause
2) using sample([%]) function
The first way has advantage in 'CORRECTNESS' which means you will never fail get result if it actually exists, while in the second way you may get no result even though it has cases satisfying the query condition since information is reduced during sampling.
The second way has advantage in 'EFFICIENT' which mean you will get result faster and give light load to your database. I was given an warning from DBA that my query using the first way gives loads to the database
You can choose one of two ways according to your interest!
Here are a few options:
In Perl, you can choose alternate delimiters. You're not confined to m//
. You could choose another, such as m{}
. Then escaping isn't necessary. As a matter of fact, Damian Conway in "Perl Best Practices" asserts that m{}
is the only alternate delimiter that ought to be used, and this is reinforced by Perl::Critic (on CPAN). While you can get away with using a variety of alternate delimiter characters, //
and {}
seem to be the clearest to decipher later on. However, if either of those choices result in too much escaping, choose whichever one lends itself best to legibility. Common examples are m(...)
, m[...]
, and m!...!
.
In cases where you either cannot or prefer not to use alternate delimiters, you can escape the forward slashes with a backslash: m/\/[^/]+$/
for example (using an alternate delimiter that could become m{/[^/]+$}
, which may read more clearly). Escaping the slash with a backslash is common enough to have earned a name and a wikipedia page: Leaning Toothpick Syndrome. In regular expressions where there's just a single instance, escaping a slash might not rise to the level of being considered a hindrance to legibility, but if it starts to get out of hand, and if your language permits alternate delimiters as Perl does, that would be the preferred solution.
You can use TypeScript's native string interpolation in case if your only goal to eliminate ugly string concatenations and boring string conversions:
var yourMessage = `Your text ${yourVariable} your text continued ${yourExpression} and so on.`
NOTE:
At the right side of the assignment statement the delimiters are neither single or double quotes, instead a special char called backtick or grave accent.
The TypeScript compiler will translate your right side special literal to a string concatenation expression. With other words this syntax is not relies the ECMAScript 6 feature instead a native TypeScript feature. Your generated javascript code remains compatible.
To complement the existing helpful answers:
Using Bash's own regex-matching operator, =~
, is a faster alternative in this case, given that you're only matching a single value already stored in a variable:
set -- '12-34-5678' # set $1 to sample value
kREGEX_DATE='^[0-9]{2}[-/][0-9]{2}[-/][0-9]{4}$' # note use of [0-9] to avoid \d
[[ $1 =~ $kREGEX_DATE ]]
echo $? # 0 with the sample value, i.e., a successful match
Note, however, that the caveat re using flavor-specific regex constructs such as \d
equally applies:
While =~
supports EREs (extended regular expressions), it also supports the host platform's specific extension - it's a rare case of Bash's behavior being platform-dependent.
To remain portable (in the context of Bash), stick to the POSIX ERE specification.
Note that =~
even allows you to define capture groups (parenthesized subexpressions) whose matches you can later access through Bash's special ${BASH_REMATCH[@]}
array variable.
Further notes:
$kREGEX_DATE
is used unquoted, which is necessary for the regex to be recognized as such (quoted parts would be treated as literals).
While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \
.
\<
is supported to match word boundaries, [[ 3 =~ \<3 ]] && echo yes
doesn't work, but re='\<3'; [[ 3 =~ $re ]] && echo yes
does.I've changed variable name REGEX_DATE
to kREGEX_DATE
(k
signaling a (conceptual) constant), so as to ensure that the name isn't an all-uppercase name, because all-uppercase variable names should be avoided to prevent conflicts with special environment and shell variables.
Here's a concise method to cut the first X characters using cut(1)

You are not setting the layout_weight
property. Your code reads weight="1"
and it should read android:layout_weight="1"
.
I have used (iTextSharp) in the past with nice results.
It would appear as though this event has some clipboardData
property attached to it (it may be nested within the originalEvent
property). The clipboardData
contains an array of items and each one of those items has a getAsString()
function that you can call. This returns the string representation of what is in the item.
Those items also have a getAsFile()
function, as well as some others which are browser specific (e.g. in webkit browsers, there is a webkitGetAsEntry()
function).
For my purposes, I needed the string value of what is being pasted. So, I did something similar to this:
$(element).bind("paste", function (e) {
e.originalEvent.clipboardData.items[0].getAsString(function (pStringRepresentation) {
debugger;
// pStringRepresentation now contains the string representation of what was pasted.
// This does not include HTML or any markup. Essentially jQuery's $(element).text()
// function result.
});
});
You'll want to perform an iteration through the items, keeping a string concatenation result.
The fact that there is an array of items makes me think more work will need to be done, analyzing each item. You'll also want to do some null/value checks.
Another easier way to print the whole string is to call values
on the dataframe.
df = pd.DataFrame({'one' : ['one', 'two',
'This is very long string very long string very long string veryvery long string']})
print(df.values)
The Output will be
[['one']
['two']
['This is very long string very long string very long string veryvery long string']]
The method you are trying to use checks if the button is active:
btnAdd.isEnabled()
When enabled, any component associated with this object is active and able to fire this object's actionPerformed method.
This method does not check if the button is pressed.
If i understand your question correctly, you want to disable your "Add" button after the user clicks "Check out".
Try disabling your button at start: btnAdd.setEnabled(false)
or after the user presses "Check out"
Try this. It uses the split
function which is a core part of javascript, nothing to do with jQuery.
var parts = html.split(":-"),
i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
$("#" + parts[i]).text(parts[i + 1]);
}
The pack
method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize
or setBounds
(which also sets the frame location). In general, using pack is preferable to calling setSize
, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.
