Its not very elegant but in case you cant change the creation of dictionary, and all you need is a dirty hack, how about this:
var item = MyDictionary.Where(x => x.Key.ToLower() == MyIndex.ToLower()).FirstOrDefault();
if (item != null)
{
TheValue = item.Value;
}
Actually I don't see any nulls:
given:
static void Main()
{
string[] testArray = new string[]
{
"aa",
"ab",
"ac",
"ad",
"ab",
"af"
};
Array.Sort(testArray, StringComparer.InvariantCulture);
Array.ForEach(testArray, x => Console.WriteLine(x));
}
I obtained:
DataTable DT = new DataTable();
DT.Columns.Add("first", typeof(string));
DT.Columns.Add("second", typeof(string));
DT.Rows.Add("ss", "test1");
DT.Rows.Add("sss", "test2");
DT.Rows.Add("sys", "test3");
DT.Rows.Add("ss", "test4");
DT.Rows.Add("ss", "test5");
DT.Rows.Add("sts", "test6");
var dr = DT.AsEnumerable().GroupBy(S => S.Field<string>("first")).Select(S => S.First()).
Select(S => new KeyValuePair<string, string>(S.Field<string>("first"), S.Field<string>("second"))).
ToDictionary(S => S.Key, T => T.Value);
foreach (var item in dr)
{
Console.WriteLine(item.Key + "-" + item.Value);
}
Use the ToDictionary
method directly.
var result =
// as Jon Skeet pointed out, OrderBy is useless here, I just leave it
// show how to use OrderBy in a LINQ query
myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
.ToDictionary(mc => mc.KeyProp.ToString(),
mc => mc.ValueProp.ToString(),
StringComparer.OrdinalIgnoreCase);
The accepted answer only shows files in the current directory's tree. To show all of the tracked files that have been committed (on the current branch), use
git ls-tree --full-tree --name-only -r HEAD
--full-tree
makes the command run as if you were in the repo's root directory.-r
recurses into subdirectories. Combined with --full-tree
, this gives you all committed, tracked files.--name-only
removes SHA / permission info for when you just want the file paths.HEAD
specifies which branch you want the list of tracked, committed files for. You could change this to master
or any other branch name, but HEAD
is the commit you have checked out right now.This is the method from the accepted answer to the ~duplicate question https://stackoverflow.com/a/8533413/4880003.
inplace=True
is used depending if you want to make changes to the original df or not.
df.drop_duplicates()
will only make a view of dropped values but not make any changes to df
df.drop_duplicates(inplace = True)
will drop values and make changes to df.
Hope this helps.:)
In my case I figured out that the session cookie had a domain that included www.
prefix, while I was requesting page with no www.
.
Adding www.
to the URL immediately fixed the problem. Later I changed cookie's domain to be set to .mysite.com
instead of www.mysite.com
.
You need:
sprintf(Buffer,"Hello World");
sprintf(Buffer + strlen(Buffer),"Good Morning");
sprintf(Buffer + strlen(Buffer),"Good Afternoon");
and of course you need your buffer to be big enough.
If you're just on Mac this tasks.json
file:
{
"version": "0.1.0",
"command": "open",
"args": ["${file}"],
}
...is all you need to open the current file in Safari, assuming its extension is ".html".
Create tasks.json
as described above and invoke it with ?+shift+b.
If you want it to open in Chrome then:
{
"version": "0.1.0",
"command": "open",
"args": ["-a", "Chrome.app", "${file}"],
}
This will do what you want, as in opening in a new tab if the app is already open.
No we can't nest forms within another form like this
<form name='form1'>
<form name='form2'>
//some code here
</form>
</form>
it will work in some cases but it is not recommended for universal platforms. You can use plenty of SUBMIT buttons inside a single form, but you can't manage a nested form appropriately.
In your onCreate()
method add this line
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
and, in the same Activity, add this method to handle the button click
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
this.finish();
return true;
}
return super.onOptionsItemSelected(item);
}
A JTable normally forms the View part of an MVC implementation. You'll want to remove rows from your model. The JTable, which should be listening for these changes, will update to reflect this removal. Hence you won't find removeRow() or similar as a method on JTable.
I ran into this issue as well. I hate to dump on EF because it works so well, but it is just slow. In most cases I just want to find a record or update/insert. Even simple operations like this are slow. I pulled back 1100 records from a table into a List and that operation took 6 seconds with EF. For me this is too long, even saving takes too long.
I ended up making my own ORM. I pulled the same 1100 records from a database and my ORM took 2 seconds, much faster than EF. Everything with my ORM is almost instant. The only limitation right now is that it only works with MS SQL Server, but it could be changed to work with others like Oracle. I use MS SQL Server for everything right now.
If you would like to try my ORM here is the link and website:
https://github.com/jdemeuse1204/OR-M-Data-Entities
Or if you want to use nugget:
PM> Install-Package OR-M_DataEntities
Documentation is on there as well
Alternatively, you could setup your submodules so that rather than being in their default detached head state you check out a branch.
Edited to add:
One way is to checkout a particular branch of the submodule when you add it with the -b flag:
git submodule add -b master <remote-repo> <path-to-add-it-to>
Another way is to just go into the submodule directory and just check it out
git checkout master
Quoting http://php.net/manual/en/intro.mssql.php:
The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.
Once you downloaded that, follow the instructions at this page:
In a nutshell:
Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:extension=php_sqlsrv_53_nts_vc9.dll
Restart the Web server.
See Also (copied from that page)
The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:
The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.
The drivers can also be used with PDO.
In newer versions(>=1.8.0) of docker, you can do this
docker build -f Dockerfile.db .
docker build -f Dockerfile.web .
A big save.
EDIT: update versions per raksja's comment
EDIT: comment from @vsevolod: it's possible to get syntax highlighting in VS code by giving files .Dockerfile extension(instead of name) e.g. Prod.Dockerfile, Test.Dockerfile etc.
Here is a better way for doing it. Hope this helps

The thing is that you are using the option -t
when running your container.
Could you check if enabling the tty
option (see reference) in your docker-compose.yml file the container keeps running?

The unwanted side effects of simple folder delete or installing over existing installation have been removed by a script written by Kyle Fuller - deintegrate and here is the proper workflow:
Install clean:
$ sudo gem install cocoapods-clean
Run deintegrate in the folder of the project:
$ pod deintegrate
Clean (this tool is no longer available):
$ pod clean
Modify your podfile (delete the lines with the pods you don't want to use anymore) and run:
$ pod install
Done.
The \s
metacharacter matches whitespace characters.
Here are the docs about the "new" format syntax. An example would be:
"({:d} goals, ${:d})".format(self.goals, self.penalties)
If both goals
and penalties
are integers (i.e. their default format is ok), it could be shortened to:
"({} goals, ${})".format(self.goals, self.penalties)
And since the parameters are fields of self
, there's also a way of doing it using a single argument twice (as @Burhan Khalid noted in the comments):
"({0.goals} goals, ${0.penalties})".format(self)
Explaining:
{}
means just the next positional argument, with default format;{0}
means the argument with index 0
, with default format;{:d}
is the next positional argument, with decimal integer format;{0:d}
is the argument with index 0
, with decimal integer format.There are many others things you can do when selecting an argument (using named arguments instead of positional ones, accessing fields, etc) and many format options as well (padding the number, using thousands separators, showing sign or not, etc). Some other examples:
"({goals} goals, ${penalties})".format(goals=2, penalties=4)
"({goals} goals, ${penalties})".format(**self.__dict__)
"first goal: {0.goal_list[0]}".format(self)
"second goal: {.goal_list[1]}".format(self)
"conversion rate: {:.2f}".format(self.goals / self.shots) # '0.20'
"conversion rate: {:.2%}".format(self.goals / self.shots) # '20.45%'
"conversion rate: {:.0%}".format(self.goals / self.shots) # '20%'
"self: {!s}".format(self) # 'Player: Bob'
"self: {!r}".format(self) # '<__main__.Player instance at 0x00BF7260>'
"games: {:>3}".format(player1.games) # 'games: 123'
"games: {:>3}".format(player2.games) # 'games: 4'
"games: {:0>3}".format(player2.games) # 'games: 004'
Note: As others pointed out, the new format does not supersede the former, both are available both in Python 3 and the newer versions of Python 2 as well. Some may say it's a matter of preference, but IMHO the newer is much more expressive than the older, and should be used whenever writing new code (unless it's targeting older environments, of course).
Mutations expect two arguments: state
and payload
, where the current state of the store is passed by Vuex itself as the first argument and the second argument holds any parameters you need to pass.
The easiest way to pass a number of parameters is to destruct them:
mutations: {
authenticate(state, { token, expiration }) {
localStorage.setItem('token', token);
localStorage.setItem('expiration', expiration);
}
}
Then later on in your actions you can simply
store.commit('authenticate', {
token,
expiration,
});
Sorry for digging out an old thread, but I think sunetos' answer isn't correct (or isn't the full answer). I've done some experiments (using ProcessStartInfo in c#) and it seems that the 'arguments' string for a commandline command is limited to 2048 characters in XP and 32768 characters in Win7. I'm not sure what the 8191 limit refers to, but I haven't found any evidence of it yet.
Among several options for shading and tinting:
For shades, multiply each component by 1/4, 1/2, 3/4, etc., of its previous value. The smaller the factor, the darker the shade.
For tints, calculate (255 - previous value), multiply that by 1/4, 1/2, 3/4, etc. (the greater the factor, the lighter the tint), and add that to the previous value (assuming each.component is a 8-bit integer).
Note that color manipulations (such as tints and other shading) should be done in linear RGB. However, RGB colors specified in documents or encoded in images and video are not likely to be in linear RGB, in which case a so-called inverse transfer function needs to be applied to each of the RGB color's components. This function varies with the RGB color space. For example, in the sRGB color space (which can be assumed if the RGB color space is unknown), this function is roughly equivalent to raising each sRGB color component (ranging from 0 through 1) to a power of 2.2. (Note that "linear RGB" is not an RGB color space.)

Some compilers may not replace any string concatenations with StringBuilder equivalents. Be sure to consider which compilers your source will use before relying on compile time optimizations.
Don't forget to call sizeToFit()
after you change image if you then use size of UIImageView to set UIScrollView contentSize and/or compute zoom scale
let image = UIImage(named: "testImage")
imageView.image = image
imageView.sizeToFit()
scrollView.contentSize = imageView.bounds.size
I solved my problem by running below command
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
$configValue = Mage::getStoreConfig('sectionName/groupName/fieldName');
sectionName, groupName and fieldName are present in etc/system.xml file of your module.
The above code will automatically fetch config value of currently viewed store.
If you want to fetch config value of any other store than the currently viewed store then you can specify store ID as the second parameter to the getStoreConfig
function as below:
$store = Mage::app()->getStore(); // store info
$configValue = Mage::getStoreConfig('sectionName/groupName/fieldName', $store);
select * from *table_name* where *datetime_column* between '01/01/2009' and curdate()
or using >=
and <=
:
select * from *table_name* where *datetime_column* >= '01/01/2009' and *datetime_column* <= curdate()
Simply said asynchronous execution is doing stuff in the background.
For example if you want to download a file from the internet you might use a synchronous function to do that but it will block your thread until the file finished downloading. This can make your application unresponsive to any user input.
Instead you could download the file in the background using asynchronous method. In this case the download function returns immediately and program execution continues normally. All the download operations are done in the background and your program will be notified when it's finished.

Nowadays you can use reversed block-based enumeration. A simple example code:
NSMutableArray *array = [@[@{@"name": @"a", @"shouldDelete": @(YES)},
@{@"name": @"b", @"shouldDelete": @(NO)},
@{@"name": @"c", @"shouldDelete": @(YES)},
@{@"name": @"d", @"shouldDelete": @(NO)}] mutableCopy];
[array enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
if([obj[@"shouldDelete"] boolValue])
[array removeObjectAtIndex:idx];
}];
Result:
(
{
name = b;
shouldDelete = 0;
},
{
name = d;
shouldDelete = 0;
}
)
another option with just one line of code:
[array filterUsingPredicate:[NSPredicate predicateWithFormat:@"shouldDelete == NO"]];
Use the Java 8 solution. Note DatatypeConverter can still be used, but it is now within the java.xml.bind
module which will need to be included.
module org.example.foo {
requires java.xml.bind;
}
Java 8 now provides java.util.Base64
for encoding and decoding base64.
Encoding
byte[] message = "hello world".getBytes(StandardCharsets.UTF_8);
String encoded = Base64.getEncoder().encodeToString(message);
System.out.println(encoded);
// => aGVsbG8gd29ybGQ=
Decoding
byte[] decoded = Base64.getDecoder().decode("aGVsbG8gd29ybGQ=");
System.out.println(new String(decoded, StandardCharsets.UTF_8));
// => hello world
Since Java 6 the lesser known class javax.xml.bind.DatatypeConverter
can be used. This is part of the JRE, no extra libraries required.
Encoding
byte[] message = "hello world".getBytes("UTF-8");
String encoded = DatatypeConverter.printBase64Binary(message);
System.out.println(encoded);
// => aGVsbG8gd29ybGQ=
Decoding
byte[] decoded = DatatypeConverter.parseBase64Binary("aGVsbG8gd29ybGQ=");
System.out.println(new String(decoded, "UTF-8"));
// => hello world
Using

Can you believe that the treeview on the image below does not use any JavaScript, but relies only on CSS3? Check out this CSS3 TreeView, which is good with Twitter BootStrap:

Assuming that you have a DHCP server running at your router I would use:
# /etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
After changing the file issue (as root):
/etc/init.d/networking restart
If the structures are of compatible types, yes, you can, with something like:
memcpy (dest_struct, source_struct, sizeof (*dest_struct));
The only thing you need to be aware of is that this is a shallow copy. In other words, if you have a char *
pointing to a specific string, both structures will point to the same string.
And changing the contents of one of those string fields (the data that the char *
points to, not the char *
itself) will change the other as well.
If you want a easy copy without having to manually do each field but with the added bonus of non-shallow string copies, use strdup
:
memcpy (dest_struct, source_struct, sizeof (*dest_struct));
dest_struct->strptr = strdup (source_struct->strptr);
This will copy the entire contents of the structure, then deep-copy the string, effectively giving a separate string to each structure.
And, if your C implementation doesn't have a strdup
(it's not part of the ISO standard), get one from here.

The best way I like in xcode5 is to change product name in building settings. Search "product name" in "building settings", and change it.
The fastest way to check if a string contains another string is using indexOf
:
if (code.indexOf('ST1') !== -1) {
// string code has "ST1" in it
} else {
// string code does not have "ST1" in it
}
os.system() returns some unix output, not the command output. So, if there is no error then exit code written as 0.
If you plan to get first element often - you can extend QuerySet in this direction:
class FirstQuerySet(models.query.QuerySet):
def first(self):
return self[0]
class ManagerWithFirstQuery(models.Manager):
def get_query_set(self):
return FirstQuerySet(self.model)
Define model like this:
class MyModel(models.Model):
objects = ManagerWithFirstQuery()
And use it like this:
first_object = MyModel.objects.filter(x=100).first()
Another way to do this would be to add this line to the assembly info of the web application:
// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
Similar to Shriek's.
I tried Noah's suggestion which leads to the best solution up to now.
Just insert \let\cleardoublepage\clearpage
before all the parts with the blank pages
Especially when you use \documentclass[12pt,a4paper]{book}
frederic snyers's advice \documentclass[oneside]{book}
is also very good and solves the problem, but if we just want to use the book.cls or article.cls, the one would make a big difference presenting your particles.
Hence, Big support to \let\cleardoublepage\clearpage
for the people who will ask the same question in the future.
Well, It's a bit late for this but I've just started learning Qt and maybe this could help somebody out there:
If you're using Qt Creator then when you've started creating the project you were asked to choose a kit to be used with your project, Let's say you chose Desktop Qt <version-here> MinGW 64-bit
. For Qt 5, If you opened the Qt folder of your installation, you'll find a folder with the version of Qt installed as its name inside it, here you can find the kits you can choose from.
You can go to /PATH/FOR/Qt/mingw<version>_64/include
and here you'll find all the includes you can use in your program, just search for QApplication
and you'll find it inside the folder QtWidgets
, So you can use #include <QtWidgets/QApplication>
since the path starts from the include
folder.
The same goes for other headers if you're stuck with any and for other kits.
Note: "all the includes you can use" doesn't mean these are the only ones you can use, If you include iostream
for example then the compiler will include it from /PATH/FOR/Qt/Tools/mingw<version>_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/c++/iostream
If in node.js, some new configurations as of Mocha v6:
Option 1: Create .mocharc.json
in project's root directory:
{
"spec": "path/to/test/files"
}
Option 2: add mocha
property in project's package.json
:
{
...
"mocha": {
"spec": "path/to/test/files"
}
}
More options are here.
Reviving an old question because it seems to appear at the top of search results.
I wanted to retain transition effects while still being able to style the actionlink so I came up with this solution.
<div class="parent-style-one"> @Html.ActionLink("Homepage", "Home", "Home") </div>
.parent-style-one { /* your styles here */ }
.parent-style-one a { text-decoration: none; }
.parent-style-one a:hover { text-decoration: underline; -webkit-transition-duration: 1.1s; /* Safari */ transition-duration: 1.1s; }
This way I only target the child elements of the div in this case the action link and still be able to apply transition effects.
Since January 7th, 2019, it is possible: unlimited free private repositories on GitHub!
... But for up to three collaborators per private repository.
Nat Friedman just announced it by twitter:
Today(!) we’re thrilled to announce unlimited free private repos for all GitHub users, and a new simplified Enterprise offering:
"New year, new GitHub: Announcing unlimited free private repos and unified Enterprise offering"
For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free.
Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly.
Starting today, those scenarios, and many more, are possible on GitHub at no cost.Public repositories are still free (of course—no changes there) and include unlimited collaborators.
For bold,
mySpannable.setSpan(new StyleSpan(Typeface.BOLD),termStart,termStop,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Another solution that doesn't require changing your existing code:

threads_list = list()
t = Thread(target=lambda q, arg1: q.put(foo(arg1)), args=(que, 'world!'))
t.start()
threads_list.append(t)
# Add more threads here
...
threads_list.append(t2)
...
threads_list.append(t3)
...
# Join all the threads
for t in threads_list:
t.join()
# Check thread's return value
while not que.empty():

I'm not familiar with napping, but using Golang's net/http
package works fine (playground):
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`)
req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
req.Header.Set("X-Custom-Header", "myvalue")
req.Header.Set("Content-Type", "application/json")
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
panic(err)
}
defer resp.Body.Close()
fmt.Println("response Status:", resp.Status)
fmt.Println("response Headers:", resp.Header)
body, _ := ioutil.ReadAll(resp.Body)
fmt.Println("response Body:", string(body))
}
Iterate over a copy instead, such as the one returned by items()

What if your lists contain duplicates like this:
v1 = ['s', 'h', 'e', 'e', 'p']
v2 = ['s', 's', 'h']
Sets do not contain duplicates. So, the following line returns True.
set(v2).issubset(v1)
To count for duplicates, you can use the code:
v1 = sorted(v1)
v2 = sorted(v2)
def is_subseq(v2, v1):
"""Check whether v2 is a subsequence of v1."""
it = iter(v1)
return all(c in it for c in v2)
So, the following line returns False.
is_subseq(v2, v1)
Both Tom and Burton's answers work for me eventually, but I had a little trouble figuring out how to apply them to a ModelChoiceField
.
The only trick to it is that the choices are stored as tuples of (<model's ID>, <model's unicode repr>)
, so if you want to set the initial model selection, you pass the model's ID as the initial value, not the object itself or it's name or anything else. Then it's as simple as:
form = EmployeeForm(initial={'manager': manager_employee_id})
Alternatively the initial
argument can be ignored in place of an extra line with:
form.fields['manager'].initial = manager_employee_id
os.path.dirname
is what you are looking for -
os.path.dirname(r"C:\folder1\folder2\filename.xml")
Make sure you prepend r
to the string so that its considered as a raw string.
Demo -
In [46]: os.path.dirname(r"C:\folder1\folder2\filename.xml")
Out[46]: 'C:\\folder1\\folder2'
If you just want folder2
, you can use os.path.basename
with the above, Example -
os.path.basename(os.path.dirname(r"C:\folder1\folder2\filename.xml"))
Demo -
In [48]: os.path.basename(os.path.dirname(r"C:\folder1\folder2\filename.xml"))
Out[48]: 'folder2'
In additional you should disable your antivirus or manage it to open 80 port on your system.
An index friendly way of doing this is:
where (field is not null and field <> '')
If there aren't many rows or this field isn't indexed, you can use:
where isnull(field,'') <> ''
First, add the iOS Simulator to Applications:
ln -s /Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app /Applications/iPhone\ Simulator.app
From there you can open it in Finder or drag it to the launch bar.

Try this. It is not watertight1, but it might be good enough:
function addhttp($url) {
if (!preg_match("@^[hf]tt?ps?://@", $url)) {
$url = "http://" . $url;
}
return $url;
}
1. That is, prefixes like "fttps://" are treated as valid.
Use show create table tbl_name
to view the foreign keys
You can use this syntax to drop a foreign key:
ALTER TABLE tbl_name DROP FOREIGN KEY fk_symbol
There's also more information here (see Frank Vanderhallen post): http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html
Just to add to everything already said, you may access the input
s either with the name
or id
using preferably the elements
property of the Object form, because without it you may get a property of the form named "foo" rather than an HTML element. And according to @Paul D. Waite it's perfectly ok to have both name and id.
var myForm = document.getElementById("myform")_x000D_
console.log(myForm.foo.value) // hey_x000D_
console.log(myForm.foo2.value) // hey_x000D_
//preferable_x000D_
console.log(myForm.elements.foo.value) // hey_x000D_
console.log(myForm.elements.foo2.value) // hey
_x000D_
<form id="myform">_x000D_
<input type="text" name="foo" id="foo2" value="hey">_x000D_
</form>
_x000D_
According to MDN on the HTMLFormElement.elements page
The HTMLFormElement property elements returns an HTMLFormControlsCollection listing all the form controls contained in the element. Independently, you can obtain just the number of form controls using the length property.
You can access a particular form control in the returned collection by using either an index or the element's name or id.
The string
class's Replace
method can also be used to remove multiple characters from a string:
Dim newstring As String
newstring = oldstring.Replace(",", "").Replace(";", "")
"[a-z]y
: Copy text to the [a-z] register
Use :!
to go to the edit command
Ctrl + R: Follow the register identity to paste what you copy.
It used to CentOS 7.
Your regex ^[0-9]
matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $
to the end:
^[0-9]*$
This accepts any number of digits, including none. To accept one or more digits, change the *
to +
. To accept exactly one digit, just remove the *
.
UPDATE: You mixed up the arguments to IsMatch
. The pattern should be the second argument, not the first:
if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))
CAUTION: In JavaScript, \d
is equivalent to [0-9]
, but in .NET, \d
by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9]
(or supply the RegexOptions.ECMAScript flag).
Consent with @georg-
I would say then why we need lame os.path.join
- better to use str.join
or unicode.join
e.g.
sys.path.append('{0}'.join(os.path.dirname(__file__).split(os.path.sep)[0:-1]).format(os.path.sep))
I have just noticed that Bjarne Stroustrup labels %
as the remainder operator, not the modulo operator.
I would bet that this is its formal name in the ANSI C & C++ specifications, and that abuse of terminology has crept in. Does anyone know this for a fact?
But if this is the case then C's fmodf() function (and probably others) are very misleading. they should be labelled fremf(), etc
Try just:
powershell.exe -noexit D:\Work\SQLExecutor.ps1 -gettedServerName "MY-PC"
Once a dom element is created, the tag is immutable, I believe. You'd have to do something like this:
$(this).replaceWith($('<h5>' + this.innerHTML + '</h5>'));
It is very simple to make a variable global in a class:
a = 0
class b():
global a
a = 10
>>> a
10
It should work the way you intended.
$array = array('value-0', 'value-1', 'value-2', 'value-3', 'value-4', 'value-5' /* … */);
$key = 4;
$value = $array[$key];
echo $value; // value-4
But maybe there is no element with the key 4
. If you want to get the fiveth item no matter what key it has, you can use array_slice
:
$value = array_slice($array, 4, 1);
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import static java.nio.file.StandardCopyOption.*;
Path yourFile = Paths.get("path_to_your_file\text.txt");
Files.move(yourFile, yourFile.resolveSibling("text1.txt"));
To replace an existing file with the name "text1.txt":
Files.move(yourFile, yourFile.resolveSibling("text1.txt"),REPLACE_EXISTING);
Delete parent:
$(document).on("click", ".remove", function() {
$(this).parent().remove();
});
Delete all parents:
$(document).on("click", ".remove", function() {
$(this).parents().remove();
});
Strangely enough,
package main
func main () {
var sessions = map[string] chan int{};
delete(sessions, "moo");
}
seems to work. This seems a poor use of resources though!
Another way is to check for existence and use the value itself:
package main
func main () {
var sessions = map[string] chan int{};
sessions["moo"] = make (chan int);
_, ok := sessions["moo"];
if ok {
delete(sessions, "moo");
}
}
You are replacing the starting tag and then putting that back in innerHTML
, so the code will be invalid. Make all the replacements before you put the code back in the element:
var html = strMessage1.innerHTML;
html = html.replace( /aaaaaa./g,'<a href=\"http://www.google.com/');
html = html.replace( /.bbbbbb/g,'/world\">Helloworld</a>');
strMessage1.innerHTML = html;
You can parse the pom file with JDOM (http://www.jdom.org/).
Server side:
if (mysql_query($query)) {

Client side:

alert("Thank you for subscribing!");
}
when you add a new data set to a geom you need to use the data=
argument. Or put the arguments in the proper order mapping=..., data=...
. Take a look at the arguments for ?geom_line
.
Thus:
p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red")
Or:
p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red")
Just put:
import { Observable} from 'rxjs';
Just like that. Nothing more or less.
At the end you will get your Public dns.
The fix is that yes, vertical padding and margin are relative to width, but top
and bottom
aren't.
So just place a div inside another, and in the inner div, use something like top:50%
(remember position
matters if it still doesn't work)
I would expect:
Use ngStorage
For All Your AngularJS Local Storage Needs. Please note that this is NOT a native part of the Angular JS framework.

Check the Demo
Try to use limit in your query. It's because of full disk as said by @Monsters X.
I have also faced this problem and solved by limit in query, because the thousands of records were there. Now working good :)
Heres a simple solution in Swift 5/iOS 13.
extension Date {
func toMilliseconds() -> Int64 {
Int64(self.timeIntervalSince1970 * 1000)
}
init(milliseconds:Int) {
self = Date().advanced(by: TimeInterval(integerLiteral: Int64(milliseconds / 1000)))
}
}
This however assumes you have calculated the difference between UTF time and local time and adjusted and accounted for in the milliseconds. For that look to calendar
var cal = Calendar.current
cal.timeZone = TimeZone(abbreviation: "UTC")!
let difference = cal.compare(dateGiven, to: date, toGranularity: .nanosecond)
I don't know which version of Python you are using but I tried this in Python 3 and made a few changes and it looks like it works. The raw_input function seems to be the issue here. I changed all the raw_input functions to "input()" and I also made minor changes to the printing to be compatible with Python 3. AJ Uppal is correct when he says that you shouldn't name a variable and a function with the same name. See here for reference:
TypeError: 'int' object is not callable
My code for Python 3 is as follows:

I noticed a small bug in your code as well. This function should ideally convert pounds to kilograms but it looks like when it prints, it is printing "Centimeters" instead of kilograms.
def convertPK():
input_P = float(input(("Pounds: ")))
P_conv = input_P * 0.45
# Printing error in the line below
print("Centimeters: {P_conv}\n")
restart = str(input("Do you wish to make another conversion? [y]Yes or [n]no: "))

I hope this helps.
I use the following to create a temp exact as the table but without the identity:
SELECT TOP 0 CONVERT(INT,0)myid,* INTO #temp FROM originaltable
ALTER TABLE #temp DROP COLUMN id
EXEC tempdb.sys.sp_rename N'#temp.myid', N'id', N'COLUMN'
Gets a warning about renames but no big deal. I use this on production class systems. Helps make sure the copy will follow any future table modifications and the temp produced is capable of getting rows additional times within a task. Please note that the PK constraint is also removed - if you need it you can add it at the end.

<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"></script>
Put this before the line that loads the additional methods.
Also, you should get the additional methods from the CDN as well, rather than jquery.bassistance.de.

Python 3.10 (use |
): Example for a function which takes a single argument that is either an int
or str
and returns either an int
or str
:
def func(arg: int | str) -> int | str:
^^^^^^^^^ ^^^^^^^^^
type of arg return type
Python 3.5 - 3.9 (use typing.Union
):
from typing import Union
def func(arg: Union[int, str]) -> Union[int, str]:
^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^
type of arg return type
For the special case of X | None
you can use Optional[X]
.
Try your code like this:
var app = express();
app.get('/test', function(req, res) {
res.sendFile('views/test.html', {root: __dirname })
});
Use res.sendFile instead of reading the file manually so express can handle setting the content-type properly for you.
You don't need the app.engine
line, as that is handled internally by express.
Some explanation (at least for Fragments - never tried with pure Activity). Hope it helps someone to understand Android better.
Most popular answer by Arun George is correct but don't work in some cases.
The answer by Marco HC uses Runnable wich is a last resort due to additional CPU load.
The answer is - you should simply choose correct place to call to setSelection(), for example it works for me:
@Override
public void onResume() {
super.onResume();
yourSpinner.setSelection(pos);
}
But it won't work in onCreateView(). I suspect that is the reason for the interest to this topic.
The secret is that with Android you can't do anything you want in any method - oops:( - components may just not be ready. As another example - you can't scroll ScrollView neither in onCreateView() nor in onResume() (see the answer here)
From the PHP Manual:
Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

Running:
npm install
from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).
You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.
To prevent this, just create a symlink to the relocated node_modules from your app dir:
ln -s ../node_modules node_modules
Be sure that the tag "php" is stick in the code like this:
?php phpinfo(); ?>
Not like this:
? php phpinfo(); ?>
OR the server will treat it as a (normal word), so the server will not understand the language you are writing to deal with it so it will be blank.

If you are using Bootstrap Tables
add this code snippet to your bootstrap_table.js
BootstrapTable.prototype.removeRow = function (params) {
if (!params.hasOwnProperty('index')) {
return;
}
var len = this.options.data.length;
if ((params.index > len) || (params.index < 0)){
return;
}
this.options.data.splice(params.index, 1);
if (len === this.options.data.length) {
return;
}
this.initSearch();
this.initPagination();
this.initBody(true);
};
Then in your var allowedMethods = [
add 'removeRow'
Finally you can use $("#your-table").bootstrapTable('removeRow',{index:1});

Without resorting gridspec entirely, the following might also be used to remove the gaps by setting wspace and hspace to zero:
import matplotlib.pyplot as plt
plt.clf()
f, axarr = plt.subplots(4, 4, gridspec_kw = {'wspace':0, 'hspace':0})
for i, ax in enumerate(f.axes):
ax.grid('on', linestyle='--')
ax.set_xticklabels([])
ax.set_yticklabels([])
plt.show()
plt.close()
Resulting in:
It really depends on what you're trying to accomplish. If you have no else clause then if(!doSomething())
seems fine. However, if you have
if(!doSomething()) {
...
}
else {
// do something else
}
I'd probably reverse that logic to remove the !
operator and make the if
clause slightly more clear.
The best way to setup Flutter on Mac
1. Open a new terminal window
2. Type: git clone https://github.com/flutter/flutter.git -b stable
Wait for the SDK to clone onto your machine
3. Type: export PATH="$PATH:`pwd`/flutter/bin", which adds flutter tool to your path
4. Type: flutter doctor , which downloads additional dependencies
Wait for dependencies to download and install
First of all, try the 32 Bit Version of the Import Wizard. This shows a lot more supported import formats.
Background: All depends on your Office (Runtimes Engines) installation.
If you dont't have Office 2007 or greater installed, the Import Wizard (32 Bit) only allows you to import Excel 97-2003 (.xls) files.
If you have the Office 2010 and geater (comes also in 64 Bit, not recommended) installed, the Import Wizard also supports Excel 2007+ (.xlsx) files.
To get an overview on the runtimes see 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine
I can think of doing it in two ways:
Storing the file in file system in any directory (say dir1
) and renaming it which ensures that the name is unique for every file (may be a timestamp) (say xyz123.jpg
), and then storing this name in some DataBase. Then while generating the JSON you pull this filename and generate a complete URL (which will be http://example.com/dir1/xyz123.png
)and insert it in the JSON.
Base 64 Encoding, It's basically a way of encoding arbitrary binary data in ASCII text. It takes 4 characters per 3 bytes of data, plus potentially a bit of padding at the end. Essentially each 6 bits of the input is encoded in a 64-character alphabet. The "standard" alphabet uses A-Z, a-z, 0-9 and + and /, with = as a padding character. There are URL-safe variants. So this approach will allow you to put your image directly in the MongoDB, while storing it Encode the image and decode while fetching it, it has some of its own drawbacks:
A.) Canvas
Load the image into an Image-Object, paint it to a canvas and convert the canvas back to a dataURL.
function convertToDataURLviaCanvas(url, callback, outputFormat){
var img = new Image();
img.crossOrigin = 'Anonymous';
img.onload = function(){
var canvas = document.createElement('CANVAS');
var ctx = canvas.getContext('2d');
var dataURL;
canvas.height = this.height;
canvas.width = this.width;
ctx.drawImage(this, 0, 0);
dataURL = canvas.toDataURL(outputFormat);
callback(dataURL);
canvas = null;
};
img.src = url;
}
Usage
convertToDataURLviaCanvas('http://bit.ly/18g0VNp', function(base64Img){
// Base64DataURL
});
Supported input formats

B.) FileReader
Load the image as blob via XMLHttpRequest and use the FileReader API to convert it to a data URL.
function convertFileToBase64viaFileReader(url, callback){
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function () {
callback(reader.result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', url);
xhr.send();
}
This approach
Usage
convertFileToBase64viaFileReader('http://bit.ly/18g0VNp', function(base64Img){
// Base64DataURL
});
I am assuming you are using java 7, thus you get a compiler warning, when you don't close the resource you should close your scanner usually in a finally block.
Scanner scanner = null;
try {
scanner = new Scanner(System.in);
//rest of the code
}
finally {
if(scanner!=null)
scanner.close();
}
Or even better: use the new Try with resource statement:
try(Scanner scanner = new Scanner(System.in)){
//rest of your code
}
You can also see this error when selecting for a union where corresponding columns can be null.
select * from (select D.dept_no, D.nullable_comment
from dept D
union
select R.dept_no, NULL
from redundant_dept R
)
This apparently confuses the parser, a solution is to assign a column alias to the always null column.
select * from (select D.dept_no, D.comment
from dept D
union
select R.dept_no, NULL "nullable_comment"
from redundant_dept R
)
The alias does not have to be the same as the corresponding column, but the column heading in the result is driven by the first query from among the union members, so it's probably a good practice.
If pressing the Insert key doesn't work, try doubleclicking the INS/OVR label in the lower right corner of Visual Studio.
What is your polynomial? If you're "processing" it, I'm envisioning some sort of tree of sub-expressions being generated at some point, and would think that it would be much simpler to use that to generate your string than to re-parse the raw expression with a regex.
Just throwing a different way of thinking out there. I'm not sure what else is going on in your app.
Varargs can be used when we are unsure about the number of arguments to be passed in a method. It creates an array of parameters of unspecified length in the background and such a parameter can be treated as an array in runtime.
If we have a method which is overloaded to accept different number of parameters, then instead of overloading the method different times, we can simply use varargs concept.
Also when the parameters' type is going to vary then using "Object...test" will simplify the code a lot.
For example:
public int calculate(int...list) {
int sum = 0;
for (int item : list) {
sum += item;
}
return sum;
}
Here indirectly an array of int type (list) is passed as parameter and is treated as an array in the code.
For a better understanding follow this link(it helped me a lot in understanding this concept clearly): http://www.javadb.com/using-varargs-in-java
P.S: Even I was afraid of using varargs when I didn't knw abt it. But now I am used to it. As it is said: "We cling to the known, afraid of the unknown", so just use it as much as you can and you too will start liking it :)
you can try :
$("#MediaPlayer").ready(function(){
$("html, body").delay(2000).animate({
scrollTop: $('#MediaPlayer').offset().top
}, 2000);
});
Font myFont = new Font("Serif", Font.BOLD, 12);
, then use a setFont method on your components like
JButton b = new JButton("Hello World");
b.setFont(myFont);
I have just uploaded this Vim plugin for the development of Java Maven projects.
And don't forget to set the highlighting if you haven't already:

In the case of a 'missing' image there are several things to consider:
When XAML can't locate a resource it might ignore it (when it won't throw a XamlParseException
)
The resource must be properly added and defined:
Make sure it exists in your project where expected.
Make sure it is built with your project as a resource.
(Right click ? Properties ? BuildAction='Resource')
Another thing to try in similar cases, which is also useful for reusing of the image (or any other resource):
Define your image as a resource in your XAML:
<UserControl.Resources>
<Image x:Key="MyImage" Source.../>
</UserControl.Resources>
And later use it in your desired control(s):
<Button Content="{StaticResource MyImage}" />
Java provides a default constructor which takes no arguments and performs no special actions or initializations, when no explicit constructors are provided.
The only action taken by the implicit default constructor is to call the superclass constructor using the super() call. Constructor arguments provide you with a way to provide parameters for the initialization of an object.
Below is an example of a cube class containing 2 constructors. (one default and one parameterized constructor).
public class Cube1 {
int length;
int breadth;
int height;
public int getVolume() {
return (length * breadth * height);
}
Cube1() {
length = 10;
breadth = 10;
height = 10;
}
Cube1(int l, int b, int h) {
length = l;
breadth = b;
height = h;
}
public static void main(String[] args) {
Cube1 cubeObj1, cubeObj2;
cubeObj1 = new Cube1();
cubeObj2 = new Cube1(10, 20, 30);
System.out.println("Volume of Cube1 is : " + cubeObj1.getVolume());
System.out.println("Volume of Cube1 is : " + cubeObj2.getVolume());
}
}
I Usually go for 422 (Unprocessable entity) if something in the required parameters didn't match what the API endpoint required (like a too short password) but for a missing parameter i would go for 406 (Unacceptable).
You want to restrict to input fields that are of type text so use the selector input[type=text]
rather than input
(which will apply to all input fields (e.g. those of type submit as well)).
When I use a non-default modules in my scripts I call the function below. Beside the module name you can provide a minimum version.
# See https://www.powershellgallery.com/ for module and version info
Function Install-ModuleIfNotInstalled(
[string] [Parameter(Mandatory = $true)] $moduleName,
[string] $minimalVersion
) {
$module = Get-Module -Name $moduleName -ListAvailable |`
Where-Object { $null -eq $minimalVersion -or $minimalVersion -ge $_.Version } |`
Select-Object -Last 1
if ($null -ne $module) {
Write-Verbose ('Module {0} (v{1}) is available.' -f $moduleName, $module.Version)
}
else {
Import-Module -Name 'PowershellGet'
$installedModule = Get-InstalledModule -Name $moduleName -ErrorAction SilentlyContinue
if ($null -ne $installedModule) {
Write-Verbose ('Module [{0}] (v {1}) is installed.' -f $moduleName, $installedModule.Version)
}
if ($null -eq $installedModule -or ($null -ne $minimalVersion -and $installedModule.Version -lt $minimalVersion)) {
Write-Verbose ('Module {0} min.vers {1}: not installed; check if nuget v2.8.5.201 or later is installed.' -f $moduleName, $minimalVersion)
#First check if package provider NuGet is installed. Incase an older version is installed the required version is installed explicitly
if ((Get-PackageProvider -Name NuGet -Force).Version -lt '2.8.5.201') {
Write-Warning ('Module {0} min.vers {1}: Install nuget!' -f $moduleName, $minimalVersion)
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Scope CurrentUser -Force
}
$optionalArgs = New-Object -TypeName Hashtable
if ($null -ne $minimalVersion) {
$optionalArgs['RequiredVersion'] = $minimalVersion
}
Write-Warning ('Install module {0} (version [{1}]) within scope of the current user.' -f $moduleName, $minimalVersion)
Install-Module -Name $moduleName @optionalArgs -Scope CurrentUser -Force -Verbose
}
}
}
usage example:
Install-ModuleIfNotInstalled 'CosmosDB' '2.1.3.528'
Please let me known if it's usefull (or not)
If you can afford working via the file data, you can do
find -mmin +14400 -delete
This worked for me
<div style="display: flex; position: absolute; width: 100%;">
<div style="white-space: nowrap; overflow: hidden;text-overflow: ellipsis;">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero. Sed cursus ante dapibus diam. Sed nisi.
</div>
</div>
Adding position:absolute
to the parent container made it work.

The problem with your macro is that once you have opened your destination Workbook (xlw
in your code sample), it is set as the ActiveWorkbook object and you get an error because TextBox1 doesn't exist in that specific Workbook. To resolve this issue, you could define a reference object to your actual Workbook before opening the other one.
Sub UploadData()
Dim xlo As New Excel.Application
Dim xlw As New Excel.Workbook
Dim myWb as Excel.Workbook
Set myWb = ActiveWorkbook
Set xlw = xlo.Workbooks.Open("c:\myworkbook.xlsx")
xlo.Worksheets(1).Cells(2, 1) = myWb.ActiveSheet.Range("d4").Value
xlo.Worksheets(1).Cells(2, 2) = myWb.ActiveSheet.TextBox1.Text
xlw.Save
xlw.Close
Set xlo = Nothing
Set xlw = Nothing
End Sub
If you prefer, you could also use myWb.Activate
to put back your main Workbook as active. It will also work if you do it with a Worksheet object. Using one or another mostly depends on what you want to do (if there are multiple sheets, etc.).

I just figured out how to do this:
It appears that when you add a parent folder to version control, Eclipse adds all sub-folders. Once the sub-folders are added to version control, it is not possible to ignore them.
Here's how to do it:
Right click on the top level folder and add to version control Right click on the child folder you want to ignore, revert Right click on the child folder you want to ignore, svn:ignore (which will now be available)
So, there is a simple fix for this. It is admittedly awkward, but it works. xcopy will not prompt to find out if the destination is a directory or file IF the new file(filename) already exists. If you precede your xcopy command with a simple echo to the new filename, it will overwrite the empty file. Example
echo.>newfile.txt
xcopy oldfile.txt newfile.txt /Y
I need to decrypt a password. The password is crypted with password_hash function.
$password = 'examplepassword'; $crypted = password_hash($password, PASSWORD_DEFAULT);
Its not clear to me if you need password_verify
, or you are trying to gain unauthorized access to the application or database. Other have talked about password_verify
, so here's how you could gain unauthorized access. Its what bad guys often do when they try to gain access to a system.
First, create a list of plain text passwords. A plain text list can be found in a number of places due to the massive data breaches from companies like Adobe. Sort the list and then take the top 10,000 or 100,000 or so.
Second, create a list of digested passwords. Simply encrypt or hash the password. Based on your code above, it does not look like a salt is being used (or its a fixed salt). This makes the attack very easy.
Third, for each digested password in the list, perform a select in an attempt to find a user who is using the password:
$sql_script = 'select * from USERS where password="'.$digested_password.'"'
Fourth, profit.
So, rather than picking a user and trying to reverse their password, the bad guy picks a common password and tries to find a user who is using it. Odds are on the bad guy's side...
Because the bad guy does these things, it would behove you to not let users choose common passwords. In this case, take a look at ProCheck, EnFilter or Hyppocrates (et al). They are filtering libraries that reject bad passwords. ProCheck achieves very high compression, and can digest multi-million word password lists into a 30KB data file.
A simplier option is to just capture the digits and replace them.
const name = 'preceding_text_0_following_text';_x000D_
const matcher = /(\d+)/;_x000D_
_x000D_
// Replace with whatever you would like_x000D_
const newName = name.replace(matcher, 'NEW_STUFF');_x000D_
console.log("Full replace", newName);_x000D_
_x000D_
// Perform work on the match and replace using a function_x000D_
// In this case increment it using an arrow function_x000D_
const incrementedName = name.replace(matcher, (match) => ++match);_x000D_
console.log("Increment", incrementedName);
_x000D_

C# has two "equals" concepts: Equals
and ReferenceEquals
. For most classes you will encounter, the ==
operator uses one or the other (or both), and generally only tests for ReferenceEquals
when handling reference types (but the string
Class is an instance where C# already knows how to test for value equality).
Equals
compares values. (Even though two separate int
variables don't exist in the same spot in memory, they can still contain the same value.)ReferenceEquals
compares the reference and returns whether the operands point to the same object in memory.Example Code:
var s1 = new StringBuilder("str");
var s2 = new StringBuilder("str");
StringBuilder sNull = null;
s1.Equals(s2); // True
object.ReferenceEquals(s1, s2); // False
s1 == s2 // True - it calls Equals within operator overload
s1 == sNull // False
object.ReferenceEquals(s1, sNull); // False
s1.Equals(sNull); // Nono! Explode (Exception)
Here is another way to get the function parameters without using any module.
def get_parameters(func):
keys = func.__code__.co_varnames[:func.__code__.co_argcount][::-1]
sorter = {j: i for i, j in enumerate(keys[::-1])}
values = func.__defaults__[::-1]
kwargs = {i: j for i, j in zip(keys, values)}
sorted_args = tuple(
sorted([i for i in keys if i not in kwargs], key=sorter.get)
)
sorted_kwargs = {
i: kwargs[i] for i in sorted(kwargs.keys(), key=sorter.get)
}
return sorted_args, sorted_kwargs
def f(a, b, c="hello", d="world"): var = a
print(get_parameters(f))
Output:
(('a', 'b'), {'c': 'hello', 'd': 'world'})
To install and run any version of Python in the same system follow my guide below.
For example say you want to install Python 2.x and Python 3.x on the same Windows system.
Install both of their binary releases anywhere you want.
Running simply the command python
the executable that is first met in PATH will be chosen for launch. In other words, add the Python directories manually. The one you add first will be selected when you type python
. Consecutive python programs (increasing order that their directories are placed in PATH) will be chosen like so:
python
python
etc.. No matter the order of "pythons" you can:
In my example I have Python 2.7.14 installed first and Python 3.5.3. This is how my PATH variable starts with:
PATH=C:\Program Files\Microsoft MPI\Bin\;C:\Python27;C:\Program Files\Python_3.6\Scripts\;C:\Program Files\Python_3.6\;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Common Files\Intel\Shared
...
Note that Python 2.7 is first and Python 3.5 second.
python
command will launch python 2.7 (if Python 3.5 the same command would launch Python 3.5). py -2
launches Python 2.7 (because it happens that the second Python is Python 3.5 which is incompatible with py -2
).
Running py -3
launches Python 3.5 (because it's Python 3.x) py -4
. This may change if/when Python version 4 is released. Now py -4
or py -5
etc. on my system outputs: Requested Python version (4) not installed
or Requested Python version (5) not installed
etc.
Hopefully this is clear enough.
Since I reached two questions searching for my problem in a slightly different way, I am replicating my answer in case you end up here.
In the called function, you can define your type with:
emitWordCount(event: { target: HTMLInputElement }) {
this.countUpdate.emit(event.target.value);
}
This assumes you are only interested in the target
property, which is the most common case. If you need to access the other properties of event
, a more comprehensive solution involves using the &
type intersection operator:
event: Event & { target: HTMLInputElement }
You can also go more specific and instead of using HTMLInputElement
you can use e.g. HTMLTextAreaElement
for textareas.
From this wikipedia entry:
The JDK is a subset of what is loosely defined as a software development kit (SDK) in the general sense. In the descriptions which accompany their recent releases for Java SE, EE, and ME, Sun acknowledge that under their terminology, the JDK forms the subset of the SDK which is responsible for the writing and running of Java programs. The remainder of the SDK is composed of extra software, such as Application Servers, Debuggers, and Documentation.
The "extra software" seems to be Glassfish, MySQL, and NetBeans. This page gives a comparison of the various packages you can get for the Java EE SDK.
We have roughly four different options to register a filter using Spring.
Firstly, we can create a Spring bean implementing Filter or extending HttpFilter:
@Component
public class MyFilter extends HttpFilter {
@Override
protected void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
throws IOException, ServletException {
// Implementation details...
chain.doFilter(request, response);
}
}
Secondly, we can create a Spring bean extending GenericFilterBean:
@Component
public class MyFilter extends GenericFilterBean {
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain)
throws IOException, ServletException {
//Implementation details...
chain.doFilter(currentRequest, servletResponse);
}
}
Alternatively we can use the FilterRegistrationBean class:
@Configuration
public class FilterConfiguration {
private final MyFilter myFilter;
@Autowired
public FilterConfiguration(MyFilter myFilter) {
this.myFilter = myFilter;
}
@Bean
public FilterRegistrationBean<MyFilter> myFilterRegistration() {
FilterRegistrationBean<DateLoggingFilter> filterRegistrationBean = new FilterRegistrationBean<>();
filterRegistrationBean.setFilter(myFilter);
filterRegistrationBean.setUrlPatterns(Collections.singletonList("/*"));
filterRegistrationBean.setDispatcherTypes(DispatcherType.REQUEST);
filterRegistrationBean.setOrder(Ordered.LOWEST_PRECEDENCE - 1);
return filterRegistrationBean;
}
}
And lastly we can use the @WebFilter annotation with @ServletComponentScan:
@WebFilter(urlPatterns = "/*", dispatcherTypes = {DispatcherType.REQUEST})
public class MyFilter extends HttpFilter {
@Override
protected void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
throws IOException, ServletException {
// Implementation details...
chain.doFilter(request, response);
}
}
public class WordChangeInCapital{
public static void main(String[] args)
{
String s="this is string example";
System.out.println(s);
//this is input data.
//this example for a string where each word must be started in capital letter
StringBuffer sb=new StringBuffer(s);
int i=0;
do{
b.replace(i,i+1,sb.substring(i,i+1).toUpperCase());
i=b.indexOf(" ",i)+1;
} while(i>0 && i<sb.length());
System.out.println(sb.length());
}
}
Simplest way.

First of all jar
creates a jar, and does not run it. Try java -jar
instead.
Second, why do you pass the class twice, as FQCN (com.mycomp.myproj.dir2.MainClass2
) and as file (com/mycomp/myproj/dir2/MainClass2.class
)?
Edit:
It seems as if java -jar
requires a main class to be specified. You could try java -cp your.jar com.mycomp.myproj.dir2.MainClass2 ...
instead. -cp
sets the jar on the classpath and enables java to look up the main class there.
As this answer says, you can also just wrap your code in an anonymous function like this:
expect(function(){
model.get('z');
}).to.throw('Property does not exist in model schema.');
In Python, the Scipy library can be used to convert the 2-D NumPy matrix into a Sparse matrix. SciPy 2-D sparse matrix package for numeric data is scipy.sparse
The scipy.sparse package provides different Classes to create the following types of Sparse matrices from the 2-dimensional matrix:
CSR (Compressed Sparse Row) or CSC (Compressed Sparse Column) formats support efficient access and matrix operations.
Example code to Convert Numpy matrix into Compressed Sparse Column(CSC) matrix & Compressed Sparse Row (CSR) matrix using Scipy classes:
import sys # Return the size of an object in bytes
import numpy as np # To create 2 dimentional matrix
from scipy.sparse import csr_matrix, csc_matrix
# csr_matrix: used to create compressed sparse row matrix from Matrix
# csc_matrix: used to create compressed sparse column matrix from Matrix
create a 2-D Numpy matrix
A = np.array([[1, 0, 0, 0, 0, 0],\
[0, 0, 2, 0, 0, 1],\
[0, 0, 0, 2, 0, 0]])
print("Dense matrix representation: \n", A)
print("Memory utilised (bytes): ", sys.getsizeof(A))
print("Type of the object", type(A))
Print the matrix & other details:
Dense matrix representation:
[[1 0 0 0 0 0]
[0 0 2 0 0 1]
[0 0 0 2 0 0]]
Memory utilised (bytes): 184
Type of the object <class 'numpy.ndarray'>
Converting Matrix A to the Compressed sparse row matrix representation using csr_matrix Class:
S = csr_matrix(A)
print("Sparse 'row' matrix: \n",S)
print("Memory utilised (bytes): ", sys.getsizeof(S))
print("Type of the object", type(S))
The output of print statements:
Sparse 'row' matrix:
(0, 0) 1
(1, 2) 2
(1, 5) 1
(2, 3) 2
Memory utilised (bytes): 56
Type of the object: <class 'scipy.sparse.csr.csc_matrix'>
Converting Matrix A to Compressed Sparse Column matrix representation using csc_matrix Class:
S = csc_matrix(A)
print("Sparse 'column' matrix: \n",S)
print("Memory utilised (bytes): ", sys.getsizeof(S))
print("Type of the object", type(S))
The output of print statements:
Sparse 'column' matrix:
(0, 0) 1
(1, 2) 2
(2, 3) 2
(1, 5) 1
Memory utilised (bytes): 56
Type of the object: <class 'scipy.sparse.csc.csc_matrix'>
As it can be seen the size of the compressed matrices is 56 bytes and the original matrix size is 184 bytes.
For a more detailed explanation and code examples please refer to this article: https://limitlessdatascience.wordpress.com/2020/11/26/sparse-matrix-in-machine-learning/
After testing the proposed solutions described above, I found only these few of lines would work.
I am using Ubuntu 16.04.
cmake_minimum_required(VERSION 3.13)

Assembly language has no direct means of printing anything. Your assembler may or may not come with a library that supplies such a facility, otherwise you have to write it yourself, and it will be quite a complex function. You also have to decide where to print things - in a window, on the printer? In assembler, none of this is done for you.
search(searchText) {
let arrayOfMatchedObjects = arrayOfAllObjects.filter(object => {
return JSON.stringify(object)
.toString()
.toLowerCase()
.includes(searchText);
});
return arrayOfMatchedObjects;
}
This could be very simple, easy, fast and understandable Search function for some of you just like me.
Just recently found out about this. With apis as:
targetSdkVersion 26
ActivityManager.getCurrentActivity(context)
Hope this is of any use.
In Python you may use the in
operator. You can do stuff like this:
>>> "c" in "abc"
True
Taking this further, you can check for complex structures, like tuples:
>>> (2, 4, 8) in ((1, 2, 3), (2, 4, 8))
True
You have to put all your assets in app/public
folder, and to access them from your views you can use asset()
helper method.
Ex. you can retrieve assets/images/image.png
in your view as following:
<img src="{{asset('assets/images/image.png')}}">
I have found one another simple way to store the data into the database
models.py
class LinkModel(models.Model):
link = models.CharField(max_length=500)
shortLink = models.CharField(max_length=30,unique=True)
In database I have only 2 variables
views.py
class HomeView(TemplateView):
def post(self,request, *args, **kwargs):
form = LinkForm(request.POST)
if form.is_valid():
text = form.cleaned_data['link'] # text for link
dbobj = LinkModel()
dbobj.link = text
self.no = self.gen.generateShortLink() # no for shortLink
dbobj.shortLink = str(self.no)
dbobj.save() # Saving from views.py
In this I have created the instance of model in views.py only and putting/saving data into 2 variables from views only.
If you're using Entity Framework, exception.ToString()
will not gives you the details of DbEntityValidationException
exceptions. You might want to use the same method to handle all your exception, like:
catch (Exception ex)
{
Log.Error(GetExceptionDetails(ex));
}
Where GetExceptionDetails
contains something like this:
public static string GetExceptionDetails(Exception ex)
{
var stringBuilder = new StringBuilder();
while (ex != null)
{
switch (ex)
{
case DbEntityValidationException dbEx:
var errorMessages = dbEx.EntityValidationErrors.SelectMany(x => x.ValidationErrors).Select(x => x.ErrorMessage);
var fullErrorMessage = string.Join("; ", errorMessages);
var message = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
stringBuilder.Insert(0, dbEx.StackTrace);
stringBuilder.Insert(0, message);
break;
default:
stringBuilder.Insert(0, ex.StackTrace);
stringBuilder.Insert(0, ex.Message);
break;
}
ex = ex.InnerException;
}
return stringBuilder.ToString();
}
Simply as bellow;
$this->db->get('table_name')->num_rows();
This will get number of rows/records. however you can use search parameters as well;
$this->db->select('col1','col2')->where('col'=>'crieterion')->get('table_name')->num_rows();
However, it should be noted that you will see bad bad errors if applying as below;
$this->db->get('table_name')->result()->num_rows();
here it it
var ffversion = '18';
var is_firefox = navigator.userAgent.toLowerCase().indexOf('firefox/'+ffversion) > -1;
alert(is_firefox);
#1- Run this to configure the region once and for all:
aws configure set region us-east-1 --profile admin
Change admin
next to the profile if it's different.
Change us-east-1
if your region is different.
#2- Run your command again:
aws ecs list-container-instances --cluster default
Your use of ERB suggests that you are in Rails. If so, then consider truncate
, a built-in helper which will do the job for you:
<% question = truncate(question, :length=>30) %>
I had a CASE statement with WHEN column = 'sometext & more text' THEN ....
I replaced it with WHEN column = 'sometext ' || CHR(38) || ' more text' THEN ...
you could also use WHEN column LIKE 'sometext _ more text' THEN ...
(_ is the wildcard for a single character)
It's worth mentioning that if you are simply using S3 for backups, you should just zip the folder and then upload that. This Will save you upload time and costs.
If you are not sure how to do efficient zipping from the terminal have a look here for OSX.
And $ zip -r archive_name.zip folder_to_compress
for Windows.
Alternatively a client such as 7-Zip would be sufficient for Windows users
What's happening is that since the the TextView is filling the whole width of the inner LinearLayout it is already in the horizontal center of the layout. When you use android:layout_gravity
it places the widget, as a whole, in the gravity specified. Instead of placing the whole widget center what you're really trying to do is place the content in the center which can be accomplished with android:gravity="center_horizontal"
and the android:layout_gravity
attribute can be removed.
This another helpful code:
"2011-05-19 10:30:14".to_datetime.strftime('%a %b %d %H:%M:%S %Z %Y')
If you follow your link, it tells you that the error results from the $injector not being able to resolve your dependencies. This is a common issue with angular when the javascript gets minified/uglified/whatever you're doing to it for production.
The issue is when you have e.g. a controller;
angular.module("MyApp").controller("MyCtrl", function($scope, $q) {
// your code
})
The minification changes $scope
and $q
into random variables that doesn't tell angular what to inject. The solution is to declare your dependencies like this:
angular.module("MyApp")
.controller("MyCtrl", ["$scope", "$q", function($scope, $q) {
// your code
}])
That should fix your problem.
Just to re-iterate, everything I've said is at the link the error message provides to you.
Simply said and without revealing the kitchen secrets:
a set in general, is a collection that contains no duplicate elements, and whose elements are in no particular order. So, A HashSet<T>
is similar to a generic List<T>
, but is optimized for fast lookups (via hashtables, as the name implies) at the cost of losing order.
The accepted answer helped me but I got tripped up while doing concatenation of varchars involving case statements. I know the OP's question does not involve case statements but I thought this would be helpful to post here for others like me who ended up here while struggling to build long dynamic SQL statements involving case statements.
When using case statements with string concatenation the rules mentioned in the accepted answer apply to each section of the case statement independently.
declare @l_sql varchar(max) = ''
set @l_sql = @l_sql +
case when 1=1 then
--without this correction the result is truncated
--CONVERT(VARCHAR(MAX), '')
+REPLICATE('1', 8000)
+REPLICATE('1', 8000)
end
print len(@l_sql)
The __import__
function can be a bit hard to understand.
If you change
i = __import__('matplotlib.text')
to
i = __import__('matplotlib.text', fromlist=[''])
then i
will refer to matplotlib.text
.
In Python 2.7 and Python 3.1 or later, you can use importlib
:
import importlib
i = importlib.import_module("matplotlib.text")
Some notes
If you're trying to import something from a sub-folder e.g. ./feature/email.py
, the code will look like importlib.import_module("feature.email")
You can't import anything if there is no __init__.py
in the folder with file you are trying to import
In MySql, alice name may not work, therefore put the original column name in the CASE statement
SELECT col1 as a, CASE WHEN col1 = 'test' THEN 'yes' END as value FROM table;
Sometimes above query also may return error, I don`t know why (I faced this problem in my two different development machine). Therefore put the CASE statement into the "(...)" as below:
SELECT col1 as a, (CASE WHEN col1 = 'test' THEN 'yes' END) as value FROM table;
if(window.location.href.indexOf("?added-to-cart=555") >= 0)
It's window.location.href
, not window.location
.
The problem, or at least one problem with your code is here:-
def insert(self,node,someNumber):
if node is None:
node = Node(someNumber)
else:
if node.data > someNumber:
self.insert(node.rchild,someNumber)
else:
self.insert(node.rchild, someNumber)
return
You see the statement "if node.data > someNumber:" and the associated "else:" statement both have the same code after them. i.e you do the same thing whether the if statement is true or false.
I'd suggest you probably intended to do different things here, perhaps one of these should say self.insert(node.lchild, someNumber) ?
Using Gradle & Lombok, here is the simplest configuration for Log4j2 that worked for me using the latest Spring Boot (2.4.1 at this time) :
configurations {
compileOnly { extendsFrom annotationProcessor }
compile.exclude module: 'spring-boot-starter-logging'
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-security'
implementation 'org.springframework.boot:spring-boot-starter-web-services'
implementation 'org.springframework.boot:spring-boot-starter-log4j2'
compileOnly 'org.projectlombok:lombok'
// (*** other dependencies ***)
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.security:spring-security-test'
}
I noticed you will get errors if you include spring-bbot-starter-log4j2
as a compileOnly
dependency instead of as an implementation
.
Just annotate your classes with @Log4j2
(or @Slf4j
) and lombok will make available a log
variable you can use for logging.
As usual, provide a log4j2.xml
configuration file in your /src/main/resources
folder.
I think you're looking for export
- though I could be wrong.. I've never played with tcsh before. Use the following syntax:
export VARIABLE=value
Use "javascript.validate.enable": false
in your VS Code settings, It doesn't disable ESLINT. I use both ESLINT & Flow. Simply follow the instructions Flow For Vs Code Setup
Adding this line in settings.json. Helps
"javascript.validate.enable": false
what you proposed with a change at the parenthesis at the Run command worked fine with VBA for me
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
Dim errorCode As Integer
wsh.Run "C:\folder\runbat.bat", windowStyle, waitOnReturn
I just used Midhat's answer but appended CopyToDataTable()
on the end.
The code below is an extension to the answer that I used to quickly enable some paging.
int pageNum = 1;
int pageSize = 25;
DataTable dtPage = dt.Rows.Cast<System.Data.DataRow>().Skip((pageNum - 1) * pageSize).Take(pageSize).CopyToDataTable();
int foo = Integer.parseInt("1001", 2);
works just fine if you are dealing with positive numbers but if you need to deal with signed numbers you may need to sign extend your string then convert to an Int
public class bit_fun {
public static void main(String[] args) {
int x= (int)Long.parseLong("FFFFFFFF", 16);
System.out.println("x =" +x);
System.out.println(signExtend("1"));
x= (int)Long.parseLong(signExtend("1"), 2);
System.out.println("x =" +x);
System.out.println(signExtend("0"));
x= (int)Long.parseLong(signExtend("0"), 2);
System.out.println("x =" +x);
System.out.println(signExtend("1000"));
x= (int)Long.parseLong(signExtend("1000"), 2);
System.out.println("x =" +x);
System.out.println(signExtend("01000"));
x= (int)Long.parseLong(signExtend("01000"), 2);
System.out.println("x =" +x);
}
private static String signExtend(String str){
//TODO add bounds checking
int n=32-str.length();
char[] sign_ext = new char[n];
Arrays.fill(sign_ext, str.charAt(0));
return new String(sign_ext)+str;
}
}
output:
x =-1
11111111111111111111111111111111
x =-1
00000000000000000000000000000000
x =0
11111111111111111111111111111000
x =-8
00000000000000000000000000001000
x =8
I hope that helps!
Since you're running Ubuntu, your system crontab is located at /etc/crontab
.
As the root user (or using sudo), you can simply edit this file and specify the user that should run this command. Here is the format of entries in the system crontab and how you should enter your command:
# m h dom mon dow user command
*/1 * * * * www-data php5 /var/www/web/includes/crontab/queue_process.php >> /var/www/web/includes/crontab/queue.log 2>&1
Of course the permissions for your php script and your log file should be set so that the www-data
user has access to them.
You can give like this
public static function getAll()
{
return $posts = $this->all()->take(2)->get();
}
And when you call statically inside your controller function also..
This is not exactly beautiful but without extra software
class timeit():
from datetime import datetime
def __enter__(self):
self.tic = self.datetime.now()
def __exit__(self, *args, **kwargs):
print('runtime: {}'.format(self.datetime.now() - self.tic))
Then you can run it like:
with timeit():
# your code, e.g.,
print(sum(range(int(1e7))))
% 49999995000000
% runtime: 0:00:00.338492
Pickle uses different protocols
to convert your data to a binary stream.
In python 2 there are 3 different protocols (0
, 1
, 2
) and the default is 0
.
In python 3 there are 5 different protocols (0
, 1
, 2
, 3
, 4
) and the default is 3
.
You must specify in python 3 a protocol lower than 3
in order to be able to load the data in python 2. You can specify the protocol
parameter when invoking pickle.dump
.
As @FelixKling pointed out, the most likely scenario is that the nodes you are looking for do not exist (yet).
However, modern development practices can often manipulate document elements outside of the document tree either with DocumentFragments or simply detaching/reattaching current elements directly. Such techniques may be used as part of JavaScript templating or to avoid excessive repaint/reflow operations while the elements in question are being heavily altered.
Similarly, the new "Shadow DOM" functionality being rolled out across modern browsers allows elements to be part of the document, but not query-able by document.getElementById and all of its sibling methods (querySelector, etc.). This is done to encapsulate functionality and specifically hide it.
Again, though, it is most likely that the element you are looking for simply is not (yet) in the document, and you should do as Felix suggests. However, you should also be aware that that is increasingly not the only reason that an element might be unfindable (either temporarily or permanently).
You can write an event handler for onsubmit
that removes the name
attribute from all of the input fields that you want not to be included in the form submission.
Here's a quick untested example:
var noSubmitElements = [ 'someFormElementID1', 'someFormElementID2' ]; //...
function submitForm() {
for( var i = 0, j = noSubmitElements.length; i < j; i++ ) {
document.getElementById(noSubmitElements[i]).removeAttribute('name');
}
}
form.onsubmit = submitForm;
Here I find the outliers in x
and substitute them with the median of a window of points (win
) around them (taking from Benjamin Bannier answer the median deviation)
def outlier_smoother(x, m=3, win=3, plots=False):
''' finds outliers in x, points > m*mdev(x) [mdev:median deviation]
and replaces them with the median of win points around them '''
x_corr = np.copy(x)
d = np.abs(x - np.median(x))
mdev = np.median(d)
idxs_outliers = np.nonzero(d > m*mdev)[0]
for i in idxs_outliers:
if i-win < 0:
x_corr[i] = np.median(np.append(x[0:i], x[i+1:i+win+1]))
elif i+win+1 > len(x):
x_corr[i] = np.median(np.append(x[i-win:i], x[i+1:len(x)]))
else:
x_corr[i] = np.median(np.append(x[i-win:i], x[i+1:i+win+1]))
if plots:
plt.figure('outlier_smoother', clear=True)
plt.plot(x, label='orig.', lw=5)
plt.plot(idxs_outliers, x[idxs_outliers], 'ro', label='outliers')
plt.plot(x_corr, '-o', label='corrected')
plt.legend()
return x_corr
If you are having trouble tracing the definitions, you can use the preprocessed output of the compiler which will tell you all you need to know. E.g.
$ cat test.c
#include <stdio.h>
$ cc -E test.c | grep off_t
typedef long int __off_t;
typedef __off64_t __loff_t;
__off_t __pos;
__off_t _old_offset;
typedef __off_t off_t;
extern int fseeko (FILE *__stream, __off_t __off, int __whence);
extern __off_t ftello (FILE *__stream) ;
If you look at the complete output you can even see the exact header file location and line number where it was defined:
# 132 "/usr/include/bits/types.h" 2 3 4
typedef unsigned long int __dev_t;
typedef unsigned int __uid_t;
typedef unsigned int __gid_t;
typedef unsigned long int __ino_t;
typedef unsigned long int __ino64_t;
typedef unsigned int __mode_t;
typedef unsigned long int __nlink_t;
typedef long int __off_t;
typedef long int __off64_t;
...
# 91 "/usr/include/stdio.h" 3 4
typedef __off_t off_t;
singletonList can hold instance of any object. Object state can be modify.
List<Character> list = new ArrayList<Character>();
list.add('X');
list.add('Y');
System.out.println("Initial list: "+ list);
List<List<Character>> list2 = Collections.singletonList(list);
list.add('Z');
System.out.println(list);
System.out.println(list2);
We can not define unmodifiableList like above.
document.getElementById("idframe").contentWindow.document.getElementById("idelement").value;
Network debugging requires Xcode 9.0 or later running on macOS 10.12.4 or later, and on the device, requires iOS 11.0 or later, or tvOS 11.0 or later.
iPhone
iOS 11 won't be available for 32bit devices, i.e. iPhone 5 and iPhone 5c and below. The first 64bit iPhone is 5s.
iPad
iPad mini 2 will be the oldest iPad with iOS 11 support.
iPod
iPod needs to be an iPod 6 to be able to run iOS.
If you use your devices not only for developing but also for production, be warned that a beta OS is not for the faint hearted ;-)
Pretty sad, eh? The way I usually do it is build up a container of iterators instead of deleting during traversal. Then loop through the container and use map.erase()
std::map<K,V> map;
std::list< std::map<K,V>::iterator > iteratorList;
for(auto i : map ){
if ( needs_removing(i)){
iteratorList.push_back(i);
}
}
for(auto i : iteratorList){
map.erase(*i)
}
Anyway, the documentation covers all the things.
Once the activity is created, the
onCreateOptionsMenu()
method is called only once, as described above. The system keeps and re-uses theMenu
you define in this method until your activity is destroyed. If you want to change the Options Menu any time after it's first created, you must override theonPrepareOptionsMenu()
method. This passes you the Menu object as it currently exists. This is useful if you'd like to remove, add, disable, or enable menu items depending on the current state of your application.
E.g.
@Override
public boolean onPrepareOptionsMenu (Menu menu) {
if (isFinalized) {
menu.getItem(1).setEnabled(false);
// You can also use something like:
// menu.findItem(R.id.example_foobar).setEnabled(false);
}
return true;
}
On Android 3.0 and higher, the options menu is considered to always be open when menu items are presented in the action bar. When an event occurs and you want to perform a menu update, you must call invalidateOptionsMenu()
to request that the system call onPrepareOptionsMenu()
.
In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager
then find Xml Tools
plugin. Tick the box and click Install
Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now
).
Following dialog will open:
Click on ...
. Point to XSD file and I am pretty sure you'll be able to handle things from here.
Hope this saves you some time.
EDIT:
Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1
plugin manager is back under a different guise... Plugin Admin
so now you can simply update notepad++ and have it back.
You need to run your test with a Spring context and a transaction manager, e.g.,
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/your-applicationContext.xml"})
@TransactionConfiguration(transactionManager="txMgr")
public class StudentSystemTest {
@Test
public void testTransactionalService() {
// test transactional service
}
@Test
@Transactional
public void testNonTransactionalService() {
// test non-transactional service
}
}
See chapter 3.5.8. Transaction Management
of the Spring reference for further details.
I needed something like that, so I went to the commons collections and used the SetUniqueList
, but when I ran some performance test, I found that it seems not optimized comparing to the case if I want to use a Set
and obtain an Array
using the Set.toArray()
method.
The SetUniqueTest
took 20:1 time to fill and then traverse 100,000 Strings comparing to the other implementation, which is a big deal difference.
So, if you worry about the performance, I recommend you to use the Set and Get an Array instead of using the SetUniqueList
, unless you really need the logic of the SetUniqueList
, then you'll need to check other solutions...
Testing code main method:
public static void main(String[] args) {
SetUniqueList pq = SetUniqueList.decorate(new ArrayList());
Set s = new TreeSet();
long t1 = 0L;
long t2 = 0L;
String t;
t1 = System.nanoTime();
for (int i = 0; i < 200000; i++) {
pq.add("a" + Math.random());
}
while (!pq.isEmpty()) {
t = (String) pq.remove(0);
}
t1 = System.nanoTime() - t1;
t2 = System.nanoTime();
for (int i = 0; i < 200000; i++) {
s.add("a" + Math.random());
}
s.clear();
String[] d = (String[]) s.toArray(new String[0]);
s.clear();
for (int i = 0; i < d.length; i++) {
t = d[i];
}
t2 = System.nanoTime() - t2;
System.out.println((double)t1/1000/1000/1000); //seconds
System.out.println((double)t2/1000/1000/1000); //seconds
System.out.println(((double) t1) / t2); //comparing results
}

Now all clients allow to do it, but it's not pretty simple.
In any Telegram client:
Administrators
It's just the wrong order
var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
$('#box').append(e);
e.attr('id', 'myid');
Append first and then access/set attr.
The best way to do this is this:
datetimepicker.Format = DatetimePickerFormat.Custom;
datetimepicker.CustomFormat = "HH:mm tt";
datetimepicker.ShowUpDowm = true;

You could also use lambda
. Useful if you're using django.utils.timezone.now
date = models.DateField(_("Date"), default=lambda: now().date())
Source article: Passing a list as an argument to a vararg method
Use the toArray(T[] arr)
method.
.getMap(locations.toArray(new WorldLocation[locations.size()]))
(toArray(new WorldLocation[0])
also works, but you would allocate a zero-length array for no reason.)
Here's a complete example:
public static void method(String... strs) {
for (String s : strs)
System.out.println(s);
}
...
List<String> strs = new ArrayList<String>();
strs.add("hello");
strs.add("world");
method(strs.toArray(new String[strs.size()]));
// ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Double quotes should work too... it should create a string, then it should APPEND/INSERT the casted STRING value of $myVar in between 2 empty strings.

What worked for me:
Go to config.inc.php.
Change
$cfg['Servers'][$i]['AllowNoPassword'] = true;
to
$cfg['Servers'][$i]['AllowNoPassword'] = false;
Change
$cfg['Servers'][$i]['password'] = '';
to
$cfg['Servers'][$i]['password'] = ' ';
Change
$cfg['Servers'][$i]['auth_type'] = 'config';
to
$cfg['Servers'][$i]['auth_type'] = 'http';
Reload the page http://localhost/phpmyadmin
Type : root
pass : (empty)
Now you have access to it. :)
The ID is only guaranteed to be generated at flush time. Persisting an entity only makes it "attached" to the persistence context. So, either flush the entity manager explicitely:
em.persist(abc);
em.flush();
return abc.getId();
or return the entity itself rather than its ID. When the transaction ends, the flush will happen, and users of the entity outside of the transaction will thus see the generated ID in the entity.
@Override
public ABC addNewABC(ABC abc) {
abcDao.insertABC(abc);
return abc;
}
For React.js, the following is what worked for me in the footer...
