Piece of cake.
Use 960Grids Go to the automatic layout builder and make a two column, fluid design. Build a left column to the width of grids that works....this is the only challenge using grids and it's very easy once you read a tutorial. In a nutshell, each column in a grid is a certain width, and you set the amount of columns you want to use. To get a column that's exactly a certain width, you have to adjust your math so that your column width is exact. Not too tough.
No chance of wrapping because others have already fought that battle for you. Compatibility back as far as you likely will ever need to go. Quick and easy....Now, download, customize and deploy.
Voila. Grids FTW.
Simply write one line in the constructor:
setResizable(false);
This will make it impossible to resize the frame.
some tests we did in our team show that A.class.isAssignableFrom(B.getClass())
works faster than B instanceof A
. this can be very useful if you need to check this on large number of elements.
Something like this:
array.sort(function(a, b){
var nameA=a.name.toLowerCase(), nameB=b.name.toLowerCase();
if (nameA < nameB) //sort string ascending
return -1;
if (nameA > nameB)
return 1;
return 0; //default return value (no sorting)
});
You are propably pasting them directly into a query. Istead you should "escape" them, using appriopriate function - mysql_real_escape_string, mysqli_real_escape_string or PDO::quote depending on extension you are using.
Many good tipps already, but the shortest and easiest (not necessarily the best) has yet to be mentioned:

Please note that this fix may only apply to IntelliJ users!! (More information at the bottom of this post that should apply to everyone.)
Fixed this problem! I use IntelliJ and it turns out I just had misconfigured the way I was including the google-play-services_lib
module as a dependency.
As I fixed this entirely through GUI and not at all by editing any files, here's a couple of screenshots:
So my Project Structure started off looking like this...
Then I removed the google-play-services
library from my dependencies list by selecting it and then clicking the minus button at the bottom. Notice the error at the bottom of the dialog, as my project absolutely does require this library. But don't worry, we'll re-add it soon!
Next I added google-play-services_lib
as a module dependency instead of a library dependency. Then I hit the up arrow button at the bottom a couple times to move this dependency to the top of the list. But notice the error at the bottom (we're still not done yet!)
I then clicked the lightbulb at the bottom of the dialog in the error message area to bring up this little small popup that gives two choices (Add to dependencies... or Remove Library). Click the Add to dependencies... option!
A new small dialog window should have popped up. It gave me two choices, one for my main project (it's name is blurred out), and then another for the google-play-services_lib
project. Yours may have a bunch more depending on your project (like you may see actionbarsherlock
, stuff like that). Select google-play-services_lib
and click okay!
And finally, you're done! I hope this helps someone else out there!
I believe the reason that this issue was happening to begin with is because I thought that I had properly included the entire google-play-services_lib
project into my overall project... but I actually had not, and had instead only properly included its jar file (google-play-services_lib/libs/google-play-services.jar
). That jar file only includes code, not Android resources values, and so as such the @integer/google_play_services_version
value was never really in my project. But the code was able to be used in my project, and so that made it seem like everything was fine.
And as a side note, fixing this issue also seems to have fixed the GooglePlayServicesUtil.getErrorDialog(...).show()
crash that I used to have. But that could also have been fixed by the update, not really 100% sure there.
If you need to manipulate it on the client side, you can't use the Visible property on the server side. Instead, set its CSS display style to "none". For example:
<asp:Label runat="server" id="Label1" style="display: none;" />
Then, you could make it visible on the client side with:
document.getElementById('Label1').style.display = 'inherit';
You could make it hidden again with:
document.getElementById('Label1').style.display = 'none';
Keep in mind that there may be issues with the ClientID being more complex than "Label1" in practice. You'll need to use the ClientID with getElementById, not the server side ID, if they differ.
Switch to the develop branch:
$ git checkout develop
Creates feature/foo branch of develop.
$ git checkout -b feature/foo develop
merge the changes to develop without a fast-forward
$ git checkout develop
$ git merge --no-ff myFeature
Now push changes to the server
$ git push origin develop
$ git push origin feature/foo
Did you try showing your window using the ShowDialog method?
Don't forget to set the Owner property on the dialog window to the main window. This will avoid weird behavior when Alt+Tabbing, etc.
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
You are somewhat close, but you should put your function inside the document.ready
event handler instead of the other-way-around.
Another way to do this is by placing your AJAX call in a generic function and call that function from an AJAX callback to loop through a set of requests in order:
$(function () {
//setup an array of AJAX options,
//each object will specify information for a single AJAX request
var ajaxes = [
{
url : '<url>',
data : {...},
callback : function (data) { /*do work on data*/ }
},
{
url : '<url2>',
data : {...},
callback : function (data) { /*maybe something different (maybe not)*/ }
}
],
current = 0;
//declare your function to run AJAX requests
function do_ajax() {
//check to make sure there are more requests to make
if (current < ajaxes.length) {
//make the AJAX request with the given info from the array of objects
$.ajax({
url : ajaxes[current].url,
data : ajaxes[current].data,
success : function (serverResponse) {
//once a successful response has been received,
//no HTTP error or timeout reached,
//run the callback for this request
ajaxes[current].callback(serverResponse);
},
complete : function () {
//increment the `current` counter
//and recursively call our do_ajax() function again.
current++;
do_ajax();
//note that the "success" callback will fire
//before the "complete" callback
}
});
}
}
//run the AJAX function for the first time once `document.ready` fires
do_ajax();
});
In this example, the recursive call to run the next AJAX request is being set as the complete
callback so that it runs regardless of the status of the current response. Meaning that if the request times out or returns an HTTP error (or invalid response), the next request will still run. If you require subsequent requests to only run when a request is successful, then using the success
callback to make your recursive call would likely be best.

It's also possible to customise your bootstrap build by using:
http://twitter.github.com/bootstrap/customize.html
All the plugins are included by default.
exitcode = data.wait()
. The child process will be blocked If it writes to standard output/error, and/or reads from standard input, and there are no peers.
A possible solution from git config
:
git config --global mergetool.keepBackup false
After performing a merge, the original file with conflict markers can be saved as a file with a
.orig
extension.
If this variable is set tofalse
then this file is not preserved.
Defaults totrue
(i.e. keep the backup files).
The alternative being not adding or ignoring those files, as suggested in this gitguru article,
git mergetool
saves the merge-conflict version of the file with a “.orig
” suffix.
Make sure to delete it before adding and committing the merge or add*.orig
to your.gitignore
.
Berik suggests in the comments to use:
find . -name \*.orig
find . -name \*.orig -delete
Charles Bailey advises in his answer to be aware of internal diff tool settings which could also generate those backup files, no matter what git settings are.
.bak
, as mentioned in its manual).So you need to reset those settings as well.
If you want to execute that command, you should probably change:
PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'
to:
PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)
# To read data from csv file
Dataset = pd.read_csv('Data.csv')
X = Dataset.iloc[:, :-1].values
# To calculate mean use imputer class
from sklearn.impute import SimpleImputer
imputer = SimpleImputer(missing_values=np.nan, strategy='mean')
imputer = imputer.fit(X[:, 1:3])
X[:, 1:3] = imputer.transform(X[:, 1:3])
Ok, per pix0r's, Sparks' and Dave's answers it looks like there are three ways to do this:
NameVirtualHost *:80
).Add your virtual host (~line 36):
<VirtualHost *:80>
DocumentRoot C:\Projects\transitCalculator\trunk
ServerName transitcalculator.localhost
<Directory C:\Projects\transitCalculator\trunk>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
Open your hosts file (C:\Windows\System32\drivers\etc\hosts).
Add
127.0.0.1 transitcalculator.localhost #transitCalculator
to the end of the file (before the Spybot - Search & Destroy stuff if you have that installed).
Now you can access that directory by browsing to http://transitcalculator.localhost/.
Starting ~line 200 of your http.conf
file, copy everything between <Directory "C:/xampp/htdocs">
and </Directory>
(~line 232) and paste it immediately below with C:/xampp/htdocs
replaced with your desired directory (in this case C:/Projects
) to give your server the correct permissions for the new directory.
Find the <IfModule alias_module></IfModule>
section (~line 300) and add
Alias /transitCalculator "C:/Projects/transitCalculator/trunk"
(or whatever is relevant to your desires) below the Alias
comment block, inside the module tags.
Edit ~line 176 in C:\xampp\apache\conf\httpd.conf; change DocumentRoot "C:/xampp/htdocs"
to #DocumentRoot "C:/Projects"
(or whatever you want).
Edit ~line 203 to match your new location (in this case C:/Projects
).
Notes:
In my case missing header files were the reason libxcb

You want str replace, because performance-wise it's much cheaper and still fits your needs!
$title = str_replace( array( '\'', '"', ',' , ';', '<', '>' ), ' ', $rawtitle);
(Unless this is all about security and sql injection, in that case, I'd rather to go with a POSITIVE list of ALLOWED characters... even better, stick with tested, proven routines.)
Btw, since the OP talked about title-setting: I wouldn't replace special chars with nothing, but with a space. A superficious space is less of a problem than two words glued together...

Things are about to change on the "eol conversion" front, with the upcoming Git 1.7.2:
A new config setting core.eol
is being added/evolved:
This is a replacement for the 'Add "
core.eol
" config variable' commit that's currently inpu
(the last one in my series).
Instead of implying that "core.autocrlf=true
" is a replacement for "* text=auto
", it makes explicit the fact thatautocrlf
is only for users who want to work with CRLFs in their working directory on a repository that doesn't have text file normalization.
When it is enabled, "core.eol" is ignored.Introduce a new configuration variable, "
core.eol
", that allows the user to set which line endings to use for end-of-line-normalized files in the working directory.
It defaults to "native
", which means CRLF on Windows and LF everywhere else. Note that "core.autocrlf
" overridescore.eol
.
This means that:[core] autocrlf = true
puts CRLFs in the working directory even if
core.eol
is set to "lf
".core.eol:
Sets the line ending type to use in the working directory for files that have the
text
property set.
Alternatives are 'lf', 'crlf' and 'native', which uses the platform's native line ending.
The default value isnative
.
Other evolutions are being considered:
For 1.8, I would consider making
core.autocrlf
just turn on normalization and leave the working directory line ending decision to core.eol, but that will break people's setups.
git 2.8 (March 2016) improves the way core.autocrlf
influences the eol:
See commit 817a0c7 (23 Feb 2016), commit 6e336a5, commit df747b8, commit df747b8 (10 Feb 2016), commit df747b8, commit df747b8 (10 Feb 2016), and commit 4b4024f, commit bb211b4, commit 92cce13, commit 320d39c, commit 4b4024f, commit bb211b4, commit 92cce13, commit 320d39c (05 Feb 2016) by Torsten Bögershausen (tboegi
).

convert.c
: refactorcrlf_action
Refactor the determination and usage of
crlf_action
.
Today, when no "crlf
" attribute are set on a file,crlf_action
is set toCRLF_GUESS
. UseCRLF_UNDEFINED
instead, and search for "text
" or "eol
" as before.Replace the old
CRLF_GUESS
usage:
CRLF_GUESS && core.autocrlf=true -> CRLF_AUTO_CRLF
CRLF_GUESS && core.autocrlf=false -> CRLF_BINARY
CRLF_GUESS && core.autocrlf=input -> CRLF_AUTO_INPUT
Make more clear, what is what, by defining:
- CRLF_UNDEFINED : No attributes set. Temparally used, until core.autocrlf
and core.eol is evaluated and one of CRLF_BINARY,
CRLF_AUTO_INPUT or CRLF_AUTO_CRLF is selected
- CRLF_BINARY : No processing of line endings.
- CRLF_TEXT : attribute "text" is set, line endings are processed.
- CRLF_TEXT_INPUT: attribute "input" or "eol=lf" is set. This implies text.
- CRLF_TEXT_CRLF : attribute "eol=crlf" is set. This implies text.
- CRLF_AUTO : attribute "auto" is set.
- CRLF_AUTO_INPUT: core.autocrlf=input (no attributes)
- CRLF_AUTO_CRLF : core.autocrlf=true (no attributes)
As torek adds in the comments:
all these translations (any EOL conversion from
eol=
orautocrlf
settings, and "clean
" filters) are run when files move from work-tree to index, i.e., duringgit add
rather than atgit commit
time.
(Note thatgit commit -a
or--only
or--include
do add files to the index at that time, though.)
For more on that, see "What is difference between autocrlf and eol".
It's not as easy as it seems to implement a control like that. Explorer works with shell items, not filesystem items (ex: the control panel, the printers folder, and so on).

Here is the best way to set your root password : Source Link Step 3 is working perfectly for me.
Commands for You
- sudo mysql
- SELECT user,authentication_string,plugin,host FROM mysql.user;
- ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
- FLUSH PRIVILEGES;
- SELECT user,authentication_string,plugin,host FROM mysql.user;
- exit
Now you can use the Password for the root user is 'password' :
- mysql -u root -p
- CREATE USER 'sammy'@'localhost' IDENTIFIED BY 'password';
- GRANT ALL PRIVILEGES ON . TO 'sammy'@'localhost' WITH GRANT OPTION;
- FLUSH PRIVILEGES;
- exit
Test your MySQL Service and Version:
systemctl status mysql.service
sudo mysqladmin -p -u root version

The data-* attributes is used to store custom data private to the page or application
So Bootstrap uses these attributes for saving states of objects
when you render
a request tou coctext
some information:
for exampel:
return render(request, 'path to template',{'username' :username , 'email'.email})
you can acces to it on template like this :
for variabels :
{% if username %}{{ username }}{% endif %}
for array :
{% if username %}{{ username.1 }}{% endif %}
{% if username %}{{ username.2 }}{% endif %}
you can also name array objects in views.py
and ten use it like:
{% if username %}{{ username.first }}{% endif %}

std::less<>
when using custom classes with operator<
If you are dealing with a set of your custom class that has operator<
defined, then you can just use std::less<>
.
As mentioned at http://en.cppreference.com/w/cpp/container/set/find C++14 has added two new find
APIs:
template< class K > iterator find( const K& x );
template< class K > const_iterator find( const K& x ) const;
which allow you to do:
main.cpp
#include <cassert>
#include <set>
class Point {
public:
// Note that there is _no_ conversion constructor,
// everything is done at the template level without
// intermediate object creation.
//Point(int x) : x(x) {}
Point(int x, int y) : x(x), y(y) {}
int x;
int y;
};
bool operator<(const Point& c, int x) { return c.x < x; }
bool operator<(int x, const Point& c) { return x < c.x; }
bool operator<(const Point& c, const Point& d) {
return c.x < d;
}
int main() {
std::set<Point, std::less<>> s;
s.insert(Point(1, -1));
s.insert(Point(2, -2));
s.insert(Point(0, 0));
s.insert(Point(3, -3));
assert(s.find(0)->y == 0);
assert(s.find(1)->y == -1);
assert(s.find(2)->y == -2);
assert(s.find(3)->y == -3);
// Ignore 1234, find 1.
assert(s.find(Point(1, 1234))->y == -1);
}
Compile and run:
g++ -std=c++14 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

As mentioned, in Swift most of the time you can achieve what you need with the ?
optional unwrapper operator. This allows you to call a method on an object if and only if the object exists (not nil
) and the method is implemented.
In the case where you still need respondsToSelector:
, it is still there as part of the NSObject
protocol.
If you are calling respondsToSelector:
on an Obj-C type in Swift, then it works the same as you would expect. If you are using it on your own Swift class, you will need to ensure your class derives from NSObject
.
Here's an example of a Swift class that you can check if it responds to a selector:
class Worker : NSObject
{
func work() { }
func eat(food: AnyObject) { }
func sleep(hours: Int, minutes: Int) { }
}
let worker = Worker()
let canWork = worker.respondsToSelector(Selector("work")) // true
let canEat = worker.respondsToSelector(Selector("eat:")) // true
let canSleep = worker.respondsToSelector(Selector("sleep:minutes:")) // true
let canQuit = worker.respondsToSelector(Selector("quit")) // false
It is important that you do not leave out the parameter names. In this example, Selector("sleep::")
is not the same as Selector("sleep:minutes:")
.
Set the default password in the .pgpass file. If the server does not save the password, it is because it is not set in the .pgpass file, or the permissions are open and the file is therefore ignored.
Read more about the password file here.
Also, be sure to check the permissions: on *nix systems the permissions on .pgpass must disallow any access to world or group; achieve this by the command chmod 0600 ~/.pgpass. If the permissions are less strict than this, the file will be ignored.
Have you tried logging-in using PGAdmin? You can save the password there, and modify the pgpass file.
You can have any length, but of course, there can be a memory issue on the computer if the String input is too long. The output is always 32 characters.
Here is how the default implementation (ASP.NET Framework or ASP.NET Core) works. It uses a Key Derivation Function with random salt to produce the hash. The salt is included as part of the output of the KDF. Thus, each time you "hash" the same password you will get different hashes. To verify the hash the output is split back to the salt and the rest, and the KDF is run again on the password with the specified salt. If the result matches to the rest of the initial output the hash is verified.
Hashing:
public static string HashPassword(string password)
{
byte[] salt;
byte[] buffer2;
if (password == null)
{
throw new ArgumentNullException("password");
}
using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, 0x10, 0x3e8))
{
salt = bytes.Salt;
buffer2 = bytes.GetBytes(0x20);
}
byte[] dst = new byte[0x31];
Buffer.BlockCopy(salt, 0, dst, 1, 0x10);
Buffer.BlockCopy(buffer2, 0, dst, 0x11, 0x20);
return Convert.ToBase64String(dst);
}
Verifying:
public static bool VerifyHashedPassword(string hashedPassword, string password)
{
byte[] buffer4;
if (hashedPassword == null)
{
return false;
}
if (password == null)
{
throw new ArgumentNullException("password");
}
byte[] src = Convert.FromBase64String(hashedPassword);
if ((src.Length != 0x31) || (src[0] != 0))
{
return false;
}
byte[] dst = new byte[0x10];
Buffer.BlockCopy(src, 1, dst, 0, 0x10);
byte[] buffer3 = new byte[0x20];
Buffer.BlockCopy(src, 0x11, buffer3, 0, 0x20);
using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, dst, 0x3e8))
{
buffer4 = bytes.GetBytes(0x20);
}
return ByteArraysEqual(buffer3, buffer4);
}

Having html collection of selects you can check if every select has option with specific value and filter those which don't match condition:
//get select collection:
let selects = $('select')
//reduce if select hasn't at least one option with value 1
.filter(function () { return [...this.children].some(el => el.value == 1) });

For those who are not satisfied with the mentioned (excellent) posts, you can use your programming skills to make a variable (PHP or whichever) and have it store the multiple class names.
That's the best hack I could come up with.
<style>
.red { color: red; }
.bold { font-weight: bold; }
</style>
<? define('DANGERTEXT','red bold'); ?>
Then apply the global variable to the element you desire rather than the class names themselves
<span class="<?=DANGERTEXT?>"> Le Champion est Ici </span>
well there are really enough examples for this, but anyway, here you go

//lets take a new CSP with a new 2048 bit rsa key pair
var csp = new RSACryptoServiceProvider(2048);

pubKey = (RSAParameters)xs.Deserialize(sr);
}
//conversion for the private key is no black magic either ... omitted
//we have a public key ... let's get a new csp and load that key
csp = new RSACryptoServiceProvider();
csp.ImportParameters(pubKey);
//we need some data to encrypt
var plainTextData = "foobar";
//for encryption, always handle bytes...
var bytesPlainTextData = System.Text.Encoding.Unicode.GetBytes(plainTextData);
//apply pkcs#1.5 padding and encrypt our data
var bytesCypherText = csp.Encrypt(bytesPlainTextData, false);
//we might want a string representation of our cypher text... base64 will do
var cypherText = Convert.ToBase64String(bytesCypherText);
/*
* some transmission / storage / retrieval
*
* and we want to decrypt our cypherText
*/
//first, get our bytes back from the base64 string ...
bytesCypherText = Convert.FromBase64String(cypherText);
//we want to decrypt, therefore we need a csp and load our private key
csp = new RSACryptoServiceProvider();
csp.ImportParameters(privKey);
//decrypt and strip pkcs#1.5 padding
bytesPlainTextData = csp.Decrypt(bytesCypherText, false);
//get our original plainText back...
plainTextData = System.Text.Encoding.Unicode.GetString(bytesPlainTextData);
}
}
}
as a side note: the calls to Encrypt() and Decrypt() have a bool parameter that switches between OAEP and PKCS#1.5 padding ... you might want to choose OAEP if it's available in your situation
Between int32
and int32_t
, (and likewise between int8
and int8_t
) the difference is pretty simple: the C standard defines int8_t
and int32_t
, but does not define anything named int8
or int32
-- the latter (if they exist at all) is probably from some other header or library (most likely predates the addition of int8_t
and int32_t
in C99).
Plain int
is quite a bit different from the others. Where int8_t
and int32_t
each have a specified size, int
can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits).
On the other hand, int
is guaranteed to be present in every implementation of C, where int8_t
and int32_t
are not. It's probably open to question whether this matters to you though. If you use C on small embedded systems and/or older compilers, it may be a problem. If you use it primarily with a modern compiler on desktop/server machines, it probably won't be.
Oops -- missed the part about char
. You'd use int8_t
instead of char if (and only if) you want an integer type guaranteed to be exactly 8 bits in size. If you want to store characters, you probably want to use char
instead. Its size can vary (in terms of number of bits) but it's guaranteed to be exactly one byte. One slight oddity though: there's no guarantee about whether a plain char
is signed or unsigned (and many compilers can make it either one, depending on a compile-time flag). If you need to ensure its being either signed or unsigned, you need to specify that explicitly.

The second parameter is optional and is the name of the target window.
If you want to create a nested dictionary given a list (arbitrary length) for a path and perform a function on an item that may exist at the end of the path, this handy little recursive function is quite helpful:
def ensure_path(data, path, default=None, default_func=lambda x: x):
"""
Function:
- Ensures a path exists within a nested dictionary
Requires:
- `data`:
- Type: dict
- What: A dictionary to check if the path exists
- `path`:
- Type: list of strs
- What: The path to check
Optional:
- `default`:
- Type: any
- What: The default item to add to a path that does not yet exist
- Default: None
- `default_func`:
- Type: function
- What: A single input function that takes in the current path item (or default) and adjusts it
- Default: `lambda x: x` # Returns the value in the dict or the default value if none was present
"""
if len(path)>1:
if path[0] not in data:
data[path[0]]={}
data[path[0]]=ensure_path(data=data[path[0]], path=path[1:], default=default, default_func=default_func)
else:
if path[0] not in data:
data[path[0]]=default
data[path[0]]=default_func(data[path[0]])
return data
Example:
data={'a':{'b':1}}
ensure_path(data=data, path=['a','c'], default=[1])
print(data) #=> {'a':{'b':1, 'c':[1]}}
ensure_path(data=data, path=['a','c'], default=[1], default_func=lambda x:x+[2])
print(data) #=> {'a': {'b': 1, 'c': [1, 2]}}
This works well for creating scripts, as you do not have to include other files:
#!/bin/bash
ssh <my_user>@<my_host> "bash -s" << EOF
# here you just type all your commmands, as you can see, i.e.
touch /tmp/test1;
touch /tmp/test2;
touch /tmp/test3;
EOF
# you can use '$(which bash) -s' instead of my "bash -s" as well
# but bash is usually being found in a standard location
# so for easier memorizing it i leave that out
# since i dont fat-finger my $PATH that bad so it cant even find /bin/bash ..
Using CSS3:
<div class="outer">
<div class="inner"/>
</div>
Css:
.outer {
display : flex;
align-items : center;
}
use "justify-content: center;" to align elements horizontally
Note: This might not work in old IE's

The one major advantage of a view over a stored procedure is that you can use a view just like you use a table. Namely, a view can be referred to directly in the FROM
clause of a query. E.g., SELECT * FROM dbo.name_of_view
.
In just about every other way, stored procedures are more powerful. You can pass in parameters, including out
parameters that allow you effectively to return several values at once, you can do SELECT
, INSERT
, UPDATE
, and DELETE
operations, etc. etc.
If you want a View's ability to query from within the FROM
clause, but you also want to be able to pass in parameters, there's a way to do that too. It's called a table-valued function.
Here's a pretty useful article on the topic:
EDIT: By the way, this sort of raises the question, what advantage does a view have over a table-valued function? I don't have a really good answer to that, but I will note that the T-SQL syntax for creating a view is simpler than for a table-valued function, and users of your database may be more familiar with views.
In C# 7 we can use tuples to accomplish this:
public List<(int SomeVariable, string AnotherVariable)> TheMethod(SomeParameter)
{
using (MyDC TheDC = new MyDC())
{
var TheQueryFromDB = (....
select new { SomeVariable = ....,
AnotherVariable = ....}
).ToList();
return TheQueryFromDB
.Select(s => (
SomeVariable = s.SomeVariable,
AnotherVariable = s.AnotherVariable))
.ToList();
}
}
You might need to install System.ValueTuple
nuget package though.
To remove a remote:
git remote remove origin
To add a remote:
git remote add origin yourRemoteUrl
and finally
git push -u origin master
I do it like this (to retrieve a specific get-parameter, here 'parameterName'):
var parameterValue = decodeURIComponent(window.location.search.match(/(\?|&)parameterName\=([^&]*)/)[2]);
In case you need to convert the returned date of a select statement to a specific format you may use the following:
select to_char(DATE (*date_you_want_to_select*)::date, 'DD/MM/YYYY') as "Formated Date"
I got the same console warning, when an ajax request was firing, so my form was also not working properly.
I disabled caching on the server's ajax call with the following response headers:
Cache-Control: no-cache, no-store, must-revalidate
Expires: -1
Pragma: no-cache
After this, the form was working. Refer to the server language (c#, php, java etc) you are using on how to add these response headers.
For me, the following did the trick:
git config --global receive.denyCurrentBranch updateInstead
I set up drive F:, almost in its entirety, to sync between my Windows 10 desktop and my Windows 10 laptop, using Git. I ended up running the above command on both machines.
First I shared the desktop's F drive on the network. Then I was able to clone it on my laptop by running:
F:
git clone 'file://///DESKTOP-PC/f'
Unfortunately, all the files ended up under "F:\f" on my laptop, not under F:\ directly. But I was able to cut and paste them manually. Git still worked from the new location afterwards.
Then I tried making some changes to files on the laptop, committing them, and pushing them back to the desktop. That didn't work until I ran the git config command mentioned above.
Note that I ran all these commands from within Windows PowerShell, on both machines.
UPDATE: I still had issues pushing changes, in some cases. I finally just started pulling changes instead, by running the following on the computer I want to pull the latest commit(s) to:
git pull --all --prune
You're missing an ending anchor.
if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
// ...
}
EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:
if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
// ...
}
try this:

This is what the res.locals object is for. Setting variables directly on the request object is not supported or documented. res.locals is guaranteed to hold state over the life of a request.
An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any). Otherwise, this property is identical to app.locals.
This property is useful for exposing request-level information such as the request path name, authenticated user, user settings, and so on.
app.use(function(req, res, next) {
res.locals.user = req.user;
res.locals.authenticated = !req.user.anonymous;
next();
});
To retrieve the variable in the next middleware:
app.use(function(req, res, next) {
if (res.locals.authenticated) {
console.log(res.locals.user.id);
}
next();
});
IntVar = int("".join(filter(str.isdigit, StringVar)))
I would also vote for Mosty Mostacho's solution with minor modification to his query code:
SELECT a.i, a.j, (
SELECT count(*) from test b where a.j >= b.j AND a.i = b.i
) AS row_number FROM test a
Which will give the same result:
+------+------+------------+
| i | j | row_number |
+------+------+------------+
| 1 | 11 | 1 |
| 1 | 12 | 2 |
| 1 | 13 | 3 |
| 2 | 21 | 1 |
| 2 | 22 | 2 |
| 2 | 23 | 3 |
| 3 | 31 | 1 |
| 3 | 32 | 2 |
| 3 | 33 | 3 |
| 4 | 14 | 1 |
+------+------+------------+
for the table:
+------+------+
| i | j |
+------+------+
| 1 | 11 |
| 1 | 12 |
| 1 | 13 |
| 2 | 21 |
| 2 | 22 |
| 2 | 23 |
| 3 | 31 |
| 3 | 32 |
| 3 | 33 |
| 4 | 14 |
+------+------+
With the only difference that the query doesn't use JOIN and GROUP BY, relying on nested select instead.
I ended up using GitKraken . I've installed, auth and connected to my repo in 30 seconds.

I was struggling with a similar logic for a few days, and after checking several forums and Q&A boards to little avail it turns out the solution was actually pretty simple.
"mondate"
is somewhat similar to "Date"
except that adding n
adds n
months rather than n
days:
> library(mondate)
> d <- as.Date("2004-01-31")
> as.mondate(d) + 1
mondate: timeunits="months"
[1] 2004-02-29

marker.setIcon(ResourcesCompat.getDrawable(getResources(), R.drawable.miubicacion, null));
Below is how I got this working.
The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.
[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]
[HttpPost]
public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)
{
var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
}
The JQuery script used to call this action method:
var requestData = {
InvoiceNumber: $.trim(this.value),
SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
};
$.ajax({
url: '/en/myController/GetDataForInvoiceNumber',
type: 'POST',
data: JSON.stringify(requestData),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
CheckIfInvoiceFound(result);
},
async: true,
processData: false
});
You can use VLOOKUP, but this requires a wrapper function to return True
or False
. Not to mention it is (relatively) slow. Use COUNTIF or MATCH instead.
Fill down this formula in column K next to the existing values in column I (from I1
to I2691
):
=COUNTIF(<entire column E range>,<single column I value>)>0
=COUNTIF($E$1:$E$99504,$I1)>0
You can also use MATCH:
=NOT(ISNA(MATCH(<single column I value>,<entire column E range>)))
=NOT(ISNA(MATCH($I1,$E$1:$E$99504,0)))

One solution to this is to bind all your callback to your object with javascript's bind
method.
You can do this with a named method,
function MyNamedMethod() {
// You can now call methods on "this" here
}
doCallBack(MyNamedMethod.bind(this));
Or with an anonymous callback
doCallBack(function () {
// You can now call methods on "this" here
}.bind(this));
Doing these instead of resorting to var self = this
shows you understand how the binding of this
behaves in javascript and doesn't rely on a closure reference.
Also, the fat arrow operator in ES6 basically is the same a calling .bind(this)
on an anonymous function:
doCallback( () => {
// You can reference "this" here now
});
A terser way, either with rev
:
x[!(!duplicated(x) & rev(!duplicated(rev(x))))]
... rather than fromLast
:
x[!(!duplicated(x) & !duplicated(x, fromLast = TRUE))]
... and as a helper function to provide either logical vector or elements from original vector :
duplicates <- function(x, as.bool = FALSE) {
is.dup <- !(!duplicated(x) & rev(!duplicated(rev(x))))
if (as.bool) { is.dup } else { x[is.dup] }
}
Treating vectors as data frames to pass to table
is handy but can get difficult to read, and the data.table
solution is fine but I'd prefer base R solutions for dealing with simple vectors like IDs.
There is a workaround by capturing clicks on document.body
and then checking event target.
document.body.addEventListener( 'click', function ( event ) {
if( event.srcElement.id == 'btnSubmit' ) {
someFunc();
};
} );
For a pure Ruby solution combine URI.parse
with CGI.parse
(this can be used even if Rails/Rack etc. are not required):
CGI.parse(URI.parse(url).query)
# => {"name1" => ["value1"], "name2" => ["value1", "value2", ...] }
I had this issue for a day until I found the real resolution. Instead of trying to force unmount an smb share that is hung, mount the share with the "soft" option. If a process attempts to connect to the share that is not available it will stop trying after a certain amount of time.
soft Make the mount soft. Fail file system calls after a number of seconds.
mount -t smbfs -o soft //username@server/share /users/username/smb/share
stat /users/username/smb/share/file
stat: /users/username/smb/share/file: stat: Operation timed out
May not be a real answer to your question but it is a solution to the problem
Don't reinvent the wheel! Import this amazing library:
https://github.com/giggsey/libphonenumber-for-php
$defaultCountry = 'SE'; // Based on the country of the user
$phoneUtil = PhoneNumberUtil::getInstance();
$swissNumberProto = $phoneUtil->parse($phoneNumber, $defaultCountry);
return $phoneUtil->format($swissNumberProto, PhoneNumberFormat::INTERNATIONAL);
It is based on Google's library for parsing, formatting, and validating international phone numbers: https://github.com/google/libphonenumber
If you dig into NSInteger's implementation:
#if __LP64__
typedef long NSInteger;
#else
typedef int NSInteger;
#endif
Simply, the NSInteger typedef does a step for you: if the architecture is 32-bit, it uses int
, if it is 64-bit, it uses long
. Using NSInteger, you don't need to worry about the architecture that the program is running on.
Here's one that works well in JavaScript. It's in a string because that's what the Dojo widget was expecting.
It matches a 10 digit North America NANP number with optional extension. Spaces, dashes and periods are accepted delimiters.
"^(\\(?\\d\\d\\d\\)?)( |-|\\.)?\\d\\d\\d( |-|\\.)?\\d{4,4}(( |-|\\.)?[ext\\.]+ ?\\d+)?$"
For MySQL Workbench 6.1: in the home window click on the server instance(connection)/ or create a new one. In the thus opened 'connection' tab click on 'server' -> 'data import'. The rest of the steps remain as in Vishy's answer.
You can iterate through arraylist to identify the index and eventually the object which you need to modify. You can use for-each for the same as below:
for(Customer customer : myList) {
if(customer!=null && "Doe".equals(customer.getName())) {
customer.setEmail("[email protected]");
break;
}
}
Here customer is a reference to the object present in Arraylist, If you change any property of this customer reference, these changes will reflect in your object stored in Arraylist.
This won't fail on Linq2Objects, but it will fail for Linq2SQL, so I am assuming that you are talking about the SQL provider or something similar.
The reason has to do with the way that the SQL provider handles your lambda expression. It doesn't take it as a function Func<P,T>
, but an expression Expression<Func<P,T>>
. It takes that expression tree and translates it so an actual SQL statement, which it sends off to the server.
The translator knows how to handle basic operators, but it doesn't know how to handle methods on objects. It doesn't know that IsNullOrEmpty(x)
translates to return x == null || x == string.empty
. That has to be done explicitly for the translation to SQL to take place.
This is how i managed to install the thing in my indigo

My answer is basically very similar to that of Rubzen. I use the image as the object value, btw. Two versions work for me:
{
"name": "Silver Card",
"logo": require('./golden-card.png'),
or
const goldenCard = require('./golden-card.png');
{ "name": "Silver Card",
"logo": goldenCard,
Without wrappers - but that is different application, too.
I have checked also "import" solution and in few cases it works (what is not surprising, that is applied in pattern App.js in React), but not in case as mine above.
Just to complement m59's correct answer, here is a working jsfiddle:
<body ng-app='myApp'>
<div>
<button my-directive>Click Me!</button>
</div>
<h1>{{2+3}}</h1>
</body>
git-bash
reports
fatal: Unable to create <Path to git repo>/.git/index.lock
: File exists.
Deleting index.lock
makes the error go away.
Or simply export VERBOSE environment variable on the shell like this:
export VERBOSE=1
$(document).ready(function(){
$('.lbOn').click();
});
Suppose this would work too.
If you want to set the background using a hex color you could do this:
var bc = new BrushConverter();
myTextBox.Background = (Brush)bc.ConvertFrom("#FFXXXXXX");
Or you could set up a SolidColorBrush resource in XAML, and then use findResource in the code-behind:
<SolidColorBrush x:Key="BrushFFXXXXXX">#FF8D8A8A</SolidColorBrush>
myTextBox.Background = (Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");
This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....
To cover the identities listed:
IIS_IUSRS:
This is analogous to the old IIS6 IIS_WPG
group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.
IUSR:
This account is analogous to the old IUSR_<MACHINE_NAME>
local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).
For more information about IIS_IUSRS
and IUSR
see:
DefaultAppPool:
If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name>
will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool
created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>
. You also won't see these pool accounts in your computers User Manager. See the following for more information:
ASP.NET v4.0:
-
This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool
above.
NETWORK SERVICE:
-
The NETWORK SERVICE
account is a built-in identity introduced on Windows 2003. NETWORK SERVICE
is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).
In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE
). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" />
setting in web.config
file locally (if that setting is locked then it would need to be done by an admin in the machine.config
file).
Setting <identity impersonate="true">
is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).
In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR
or a specific custom anonymous account.
LOCAL SERVICE:
The LOCAL SERVICE
account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:
LOCAL SYSTEM:
You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.
In Practice:
In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity
. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity
:
In the website you should then configure the Authentication feature:
Right click and edit the Anonymous Authentication entry:
Ensure that "Application pool identity" is selected:
When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0
pool permissions then you can either do this via Explorer:
Click the "Check Names" button:
Or you can do this using the ICACLS.EXE
utility:
icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)
...or...if you site's application pool is called BobsCatPicBlog
then:
icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)
I hope this helps clear things up.
Update:
I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:
The difference between the 'Local System' account and the 'Network Service' account?
Use the method setAnimation(null) to stop an animation, it exposed as public method in
View.java, it is the base class for all widgets, which are used to create interactive UI components (buttons, text fields, etc.).
/**
* Sets the next animation to play for this view.
* If you want the animation to play immediately, use
* {@link #startAnimation(android.view.animation.Animation)} instead.
* This method provides allows fine-grained
* control over the start time and invalidation, but you
* must make sure that 1) the animation has a start time set, and
* 2) the view's parent (which controls animations on its children)
* will be invalidated when the animation is supposed to
* start.
*
* @param animation The next animation, or null.
*/
public void setAnimation(Animation animation)
If a pipeline is too complicated to wrap in $(...)
, consider writing a function. Any local variables available at the time of definition will be accessible.

If you have es6-shim
or your tsconfig.json
target es6
, you could use ES6 Map to make it.
var myDict = new Map();
myDict.set('key1','value1');
myDict.set('key2','value2');
<div *ngFor="let keyVal of myDict.entries()">
key:{{keyVal[0]}}, val:{{keyVal[1]}}
</div>
XSLT.
XSLT is weird enough that most people just ignore it. If you must use it, you need an XSLT Shaman to give you the magic incantations to make things go.
The data.table
package has its IDate
class and functionalities similar to lubridate
or the zoo
package. You could do:
dt = data.table(
Name = c('Joe', 'Amy', 'John'),
JoiningDate = c('12/31/09', '10/28/09', '05/06/10'),
AmtPaid = c(1000, 100, 200)
)
require(data.table)
dt[ , JoiningDate := as.IDate(JoiningDate, '%m/%d/%y') ]
You can keep note of below possibilities:
null
.However with multiple null
keys and values it will only take a null key value pair once.
Map<String, String> codes = new HashMap<String, String>();
codes.put(null, null);
codes.put(null,null);
codes.put("C1", "Acathan");
for(String key:codes.keySet()){
System.out.println(key);
System.out.println(codes.get(key));
}
output will be :
null //key of the 1st entry
null //value of 1st entry
C1
Acathan
null
only onceoptions.put(null, null);
Person person = sample.searchPerson(null);
It depends on the implementation of your searchPerson
method
if you want multiple values to be null
, you can implement accordingly
Map<String, String> codes = new HashMap<String, String>();
codes.put(null, null);
codes.put("X1",null);
codes.put("C1", "Acathan");
codes.put("S1",null);
for(String key:codes.keySet()){
System.out.println(key);
System.out.println(codes.get(key));
}
output:
null
null
X1
null
S1
null
C1
Acathan
The real reason because set
does not work is the fact, that it uses the hash function to distinguish different values. This means that sets only allows hashable objects. Why a list is not hashable is already pointed out.
from datetime import datetime, timedelta
yesterday = datetime.now() - timedelta(days=1)
yesterday.strftime('%m%d%y')
To change all classes for an element:
document.getElementById("ElementID").className = "CssClass";
To add an additional class to an element:
document.getElementById("ElementID").className += " CssClass";
To check if a class is already applied to an element:
if ( document.getElementById("ElementID").className.match(/(?:^|\s)CssClass(?!\S)/) )
If the machine is being a firewall then your solution is a very sensible one: the alternative being able to query the firewall which ends-up being very dependent on the type of firewall (if at all possible).
You can also use the latest

Am I getting it because the act of calling it via e.extractAll("th") also passes in self as an argument?
Yes, that's precisely it. If you like, the first parameter is the object name, e
that you are calling it with.
And if so, by removing the self in the call, would I be making it some kind of class method that can be called like Extractor.extractAll("th")?
Not quite. A classmethod needs the @classmethod
decorator, and that accepts the class as the first paramater (usually referenced as cls
). The only sort of method that is given no automatic parameter at all is known as a staticmethod, and that again needs a decorator (unsurprisingly, it's @staticmethod
). A classmethod is used when it's an operation that needs to refer to the class itself: perhaps instantiating objects of the class; a staticmethod is used when the code belongs in the class logically, but requires no access to class or instance.
But yes, both staticmethods and classmethods can be called by referencing the classname as you describe: Extractor.extractAll("th")
.
The li
tag has a property called list-style-position
. This makes your bullets inside or outside the list. On default, it’s set to inside
. That makes your text wrap around it. If you set it to outside
, the text of your li
tags will be aligned.
The downside of that is that your bullets won't be aligned with the text outside the ul
. If you want to align it with the other text you can use a margin.
ul li {
/*
* We want the bullets outside of the list,
* so the text is aligned. Now the actual bullet
* is outside of the list’s container
*/
list-style-position: outside;
/*
* Because the bullet is outside of the list’s
* container, indent the list entirely
*/
margin-left: 1em;
}

elementAfter making the change suggested above by Martin, I was still getting the same error. I had to make an additional change to my parsing code. I was parsing the XML file via a DocumentBuilder as shown in the oracle docs: https://docs.oracle.com/javase/7/docs/api/javax/xml/validation/package-summary.html
// parse an XML document into a DOM tree
DocumentBuilder parser = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = parser.parse(new File("example.xml"));
The problem was that DocumentBuilder is not namespace aware by default. The following additional change resolved the issue:
// parse an XML document into a DOM tree
DocumentBuilderFactory dmfactory = DocumentBuilderFactory.newInstance();
dmfactory.setNamespaceAware(true);
DocumentBuilder parser = dmfactory.newDocumentBuilder();
Document document = parser.parse(new File("example.xml"));
I've been using Bitvise SSH Server and it's really great. From install to administration it does it all through a GUI so you won't be putting together a sshd_config file. Plus if you use their client, Tunnelier, you get some bonus features (like mapping shares, port forwarding setup up server side, etc.) If you don't use their client it will still work with the Open Source SSH clients.
It's not Open Source and it costs $39.95, but I think it's worth it.
UPDATE 2009-05-21 11:10: The pricing has changed. The current price is $99.95 per install for commercial, but now free for non-commercial/personal use. Here is the current pricing.
parser.add_argument
also has a switch required. You can use required=False
.
Here is a sample snippet with Python 2.7:
parser = argparse.ArgumentParser(description='get dir')
parser.add_argument('--dir', type=str, help='dir', default=os.getcwd(), required=False)
args = parser.parse_args()
you can use numpy to avoid looping:

In your component
let today: string;
ngOnInit() {
this.today = new Date().toISOString().split('T')[0];
}
and in your html file
<input name="date" [(ngModel)]="today" type="date" required>
For Java 11 you can use new HTTP client:
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("http://localhost/api"))
.header("Content-Type", "application/json")
.POST(ofInputStream(() -> getClass().getResourceAsStream(
"/some-data.json")))
.build();
client.sendAsync(request, BodyHandlers.ofString())
.thenApply(HttpResponse::body)
.thenAccept(System.out::println)
.join();
You can use publisher from InputStream, String, File. Converting JSON to the String or IS you can with Jackson.
In the query design:
Note:
If you don't sort, the field will be removed by access. So, make sure you've unchecked show and sorted the column.
I received this error when I tried to launch app from Xcode as I figured I had selected distribution profile only. Build was successful so I created .ipa file. I used testflightapp.com to run the app. You can use iTunes as well.

Here's an example I found on this blog.
$cn2 = new-object system.data.SqlClient.SQLConnection("Data Source=machine1;Integrated Security=SSPI;Initial Catalog=master");
$cmd = new-object system.data.sqlclient.sqlcommand("dbcc freeproccache", $cn2);
$cn2.Open();
if ($cmd.ExecuteNonQuery() -ne -1)
{
echo "Failed";
}
$cn2.Close();
Presumably you could substitute a different TSQL statement where it says dbcc freeproccache
.
Here is simple code. You must set an id for your input. Here call it 'myInput':
var myform = document.getElementById('myform');
myform.onsubmit = function(){
document.getElementById('myInput').value = '1';
myform.submit();
};

For those having issues with selection highlight for the top and bottom row where the background rectangle shows up on selection you need to set the selector for your listview to transparent color.
listView.setSelector(R.color.transparent);
In color.xml just add the following -
<color name="transparent">#00000000</color>
For all of you who answered correctly with the jQuery method of $('#idnamehere').show()/.hide()
, thank you.
It seems <script src="http://code.jquery.com/jquery.js"></script>

Thanks a million, though, and sorry for wasting your time!
This is how I got rid of the error:
WebDriverException: Error forwarding the new session cannot find : {platform=WINDOWS, ensureCleanSession=true, browserName=internet explorer, version=11}
In your nodeconfig.json, the version must be a String, not an integer.
So instead of using "version": 11
use "version": "11"
(note the double quotes).

PDO is the standard, it's what most developers will expect to use. mysqli was essentially a bespoke solution to a particular problem, but it has all the problems of the other DBMS-specific libraries. PDO is where all the hard work and clever thinking will go.

I think the workaround should be set it as

Yes, you can use jQuery to make this done, the idea is
Use a hidden value in your form, and copy the value from external text box to this hidden value just before submitting the form.
<form name="input" action="handle_email.php" method="post">
<input type="hidden" name="email" id="email" />
<input type="submit" value="Submit" />
</form>
<script>
$("form").submit(function() {
var emailFromOtherTextBox = $("#email_textbox").val();
$("#email").val(emailFromOtherTextBox );
return true;
});
</script>

I recently faced similar issue where the atom editor will not close. Neither was responding. Kill / kill -9 / force exit from Activity Monitor - didn't work. Finally had to restart my mac to close the app.
Given
volumes:
- /dir/on/host:/var/www/html
if /dir/on/host
doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html
. Whatever content you had before in /var/www/html
inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.
we had similar header issue with Amazon (AWS) S3 presigned Post failing on some browsers.

Use Test-Path:
if (!(Test-Path $exactadminfile) -and !(Test-Path $userfile)) {
Write-Warning "$userFile absent from both locations"
}
Placing the above code in your ForEach
loop should do what you want
srand(time(NULL));
int nRandonNumber = rand()%((nMax+1)-nMin) + nMin;
printf("%d\n",nRandonNumber);
It seems that your
$(".modal").on('shown.bs.modal') // One way Or
You can do this in a slight different way, like this
$('.btn').click(function(){
// Send the src on click of button to the iframe. Which will make it load.
$(".openifrmahere").find('iframe').attr("src","http://www.hf-dev.info");
$('.modal').modal({show:true});
// Hide the loading message
$(".openifrmahere").find('iframe').load(function() {
$('.loading').hide();
});
})
If you have moved your project to new machine or importing it from git, then try this.
It worked for me.
The accepted answer is correct but I will rewrite complete steps for java
.
I am currently using Swagger V2
with Spring Boot 2
and it's straightforward 3 step process.
Step 1: Add required dependencies in pom.xml
file. The second dependency is optional use it only if you need Swagger UI
.
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
Step 2: Add configuration class
@Configuration
@EnableSwagger2
public class SwaggerConfig {
public static final Contact DEFAULT_CONTACT = new Contact("Usama Amjad", "https://stackoverflow.com/users/4704510/usamaamjad", "[email protected]");
public static final ApiInfo DEFAULT_API_INFO = new ApiInfo("Article API", "Article API documentation sample", "1.0", "urn:tos",
DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList<VendorExtension>());
@Bean
public Docket api() {
Set<String> producesAndConsumes = new HashSet<>();
producesAndConsumes.add("application/json");
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(DEFAULT_API_INFO)
.produces(producesAndConsumes)
.consumes(producesAndConsumes);
}
}
Step 3: Setup complete and now you need to document APIs in controllers
@ApiOperation(value = "Returns a list Articles for a given Author", response = Article.class, responseContainer = "List")
@ApiResponses(value = { @ApiResponse(code = 200, message = "Success"),
@ApiResponse(code = 404, message = "The resource you were trying to reach is not found") })
@GetMapping(path = "/articles/users/{userId}")
public List<Article> getArticlesByUser() {
// Do your code
}
Usage:
You can access your Documentation from http://localhost:8080/v2/api-docs
just copy it and paste in Postman to import collection.
Optional Swagger UI: You can also use standalone UI without any other rest client via http://localhost:8080/swagger-ui.html
and it's pretty good, you can host your documentation without any hassle.
Recaptcha contact form 7 and Recaptcha v3 solution.

}
More Than One Contact Form Page?
body:not(.page-id-12):not(.page-id-43) .grecaptcha-badge {

You can add more “nots” if you have more contact form pages.
body:not(.page-id-45):not(.page-id-78):not(.page-id-98) .grecaptcha-badge {

}
Make sure that your body section will like this:
<body>
Change it so that it looks like this:

Seems like an old question but still relevant.
I think it is a blocked update issue.
The main problem is the new URL (route) is supposed to be rendered by the same component(Costumers
) as you are currently in (current URL).
So solution is rather simple, make the window url as a prop, so react has a chance to detect the prop change (therefore the url change), and act accordingly.
A nice usecase described in the official react blog called Recommendation: Fully uncontrolled component with a key.
So the solution is to change from
render() {
return(
<ul>
to
render() {
return(
<ul key={this.props.location.pathname}>
So whenever the location changed by react-router, the component got scrapped (by react) and a new one gets initiated with the right values (by react).
Oh, and pass the location
as prop to the component(Costumers
) where the redirect will happen if it is not passed already.
Hope it helps someone.
Since it seems nobody mentioned deepdiff
, I will add it here for completeness. I find it very convenient for getting diff of (nested) objects in general:
pip install deepdiff
import deepdiff
import json
dict_1 = {
"a": 1,
"nested": {
"b": 1,
}
}
dict_2 = {
"a": 2,
"nested": {
"b": 2,
}
}
diff = deepdiff.DeepDiff(dict_1, dict_2)
print(json.dumps(diff, indent=4))
{
"values_changed": {
"root['a']": {
"new_value": 2,
"old_value": 1
},
"root['nested']['b']": {
"new_value": 2,
"old_value": 1
}
}
}
Note about pretty-printing the result for inspection: The above code works if both dicts have the same attribute keys (with possibly different attribute values as in the example). However, if an "extra"
attribute is present is one of the dicts, json.dumps()
fails with
TypeError: Object of type PrettyOrderedSet is not JSON serializable
Solution: use diff.to_json()
and json.loads()
/ json.dumps()
to pretty-print:
import deepdiff
import json
dict_1 = {
"a": 1,
"nested": {
"b": 1,
},
"extra": 3
}
dict_2 = {
"a": 2,
"nested": {
"b": 2,
}
}
diff = deepdiff.DeepDiff(dict_1, dict_2)
print(json.dumps(json.loads(diff.to_json()), indent=4))
Output:
{
"dictionary_item_removed": [
"root['extra']"
],

"old_value": 1
},
"root['nested']['b']": {

}
Alternative: use pprint
, results in a different formatting:
import pprint
# same code as above
pprint.pprint(diff, indent=4)
Output:

'old_value': 1},
"root['nested']['b']": { 'new_value': 2,
'old_value': 1}}}
Tested Code:
$("input").css("background","red");
Complete:
$('input:text').focus(function () {
$(this).css({ 'background': 'Black' });
});
$('input:text').blur(function () {
$(this).css({ 'background': 'red' });
});

The @Nadun's version did not work for me, sizing wasn't working well. Removed the direction="column"
or changing it to row
, helps with building vertical login forms with responsive sizing.
<Grid
container
spacing={0}
alignItems="center"
justify="center"
style={{ minHeight: "100vh" }}
>
<Grid item xs={6}></Grid>
</Grid>;
Import the entire JQuery's contents in the Global scope. This inserts $ into the current scope, containing all the exported bindings from the JQuery.
import * as $ from 'jquery';
Now the $ belongs to the window object.
Interestingly enough, it is possible to initialize arrays in any way at any time in the program, provided they are members of a struct
or union
.
Example program:
#include <stdio.h>
struct ccont
{
char array[32];
};
struct icont
{
int array[32];
};
int main()
{
int cnt;
char carray[32] = { 'A', 66, 6*11+1 }; // 'A', 'B', 'C', '\0', '\0', ...
int iarray[32] = { 67, 42, 25 };
struct ccont cc = { 0 };
struct icont ic = { 0 };
/* these don't work
carray = { [0]=1 }; // expected expression before '{' token
carray = { [0 ... 31]=1 }; // (likewise)
carray = (char[32]){ [0]=3 }; // incompatible types when assigning to type 'char[32]' from type 'char *'
iarray = (int[32]){ 1 }; // (likewise, but s/char/int/g)
*/
// but these perfectly work...
cc = (struct ccont){ .array='a' }; // 'a', '\0', '\0', '\0', ...
// the following is a gcc extension,
cc = (struct ccont){ .array={ [0 ... 2]='a' } }; // 'a', 'a', 'a', '\0', '\0', ...
ic = (struct icont){ .array={ 42,67 } }; // 42, 67, 0, 0, 0, ...
// index ranges can overlap, the latter override the former
// (no compiler warning with -Wall -Wextra)
ic = (struct icont){ .array={ [0 ... 1]=42, [1 ... 2]=67 } }; // 42, 67, 67, 0, 0, ...
for (cnt=0; cnt<5; cnt++)
printf("%2d %c %2d %c\n",iarray[cnt], carray[cnt],ic.array[cnt],cc.array[cnt]);
return 0;
}

If you want to enable debug logging in tomcat for TLD scanned jars then you have to change /conf/logging.properties file in tomcat directory.
uncomment the line :
org.apache.jasper.servlet.TldScanner.level = FINE
FINE level is for debug log.
This should work for normal tomcat.
If the tomcat is running under eclipse. Then you have to set the path of tomcat logging.properties in eclipse.
Now the jar files that scanned for TLDs should show in the log.
PeanutButter.INI is a Nuget-packaged class for INI files manipulation. It supports read/write, including comments – your comments are preserved on write. It appears to be reasonably popular, is tested and easy to use. It's also totally free and open-source.

Or something else you were shooting for?
From Django docs:
The include tag should be considered as an implementation of "render this subtemplate and include the HTML", not as "parse this subtemplate and include its contents as if it were part of the parent". This means that there is no shared state between included templates -- each include is a completely independent rendering process.
So Django doesn't grab any blocks from your commondata.html and it doesn't know what to do with rendered html outside blocks.
Why should not use jquery popup for this purpose.I use bpopup
for this purpose.See more about this.
http://dinbror.dk/bpopup/
Just add this to your Action file in some div or td, so that it comes with incoming XML object
<script type="text/javascript">
$("#formname").resetForm();
</script>
Where "formname" is the id of form you want to edit
I wasn't able to use Model::truncate()
as it would error:
SQLSTATE[42000]: Syntax error or access violation: 1701 Cannot truncate a table referenced in a foreign key constraint
And unfortunately Model::delete()
doesn't work (at least in Laravel 5.0):
Non-static method Illuminate\Database\Eloquent\Model::delete() should not be called statically, assuming $this from incompatible context
But this does work:
(new Model)->newQuery()->delete()
That will soft-delete all rows, if you have soft-delete set up. To fully delete all rows including soft-deleted ones you can change to this:
(new Model)->newQueryWithoutScopes()->forceDelete()
You can go to IE Tools -> Internet options -> Advanced Tab
. Under Advanced, check for security and put a check on the 1st 2 options which says,"Allow active content from CDs to run on My Computer* and Allow active content to run in files on My Computer*"
Restart your browser and the ActiveX scripts will not be shown.
Changing from hauth.done=Facebook to hauth_done=Facebook in the Valid OAuth redirect URIs fixed it for me.
jnettop is another candidate.

It sounds like you have a memory leak. The problem isn't handling many images, it's that your images aren't getting deallocated when your activity is destroyed.
It's difficult to say why this is without looking at your code. However, this article has some tips that might help:
http://android-developers.blogspot.de/2009/01/avoiding-memory-leaks.html
In particular, using static variables is likely to make things worse, not better. You might need to add code that removes callbacks when your application redraws -- but again, there's not enough information here to say for sure.
In MacOS Cmd+C is useful to minimizing the full screen
No -- AL is the 8 least significant bits of AX. AX is the 16 least significant bits of EAX.
Perhaps it's easiest to deal with if we start with 04030201h in eax. In this case, AX will contain 0201h, AH wil contain 02h and AL will contain 01h.
I think this would be a more simpler way of outputting your results.
Sorry for using my own data should be easy to replace .
$query = "SELECT * FROM category ";
$result = mysqli_query($connection, $query);
while($row = mysqli_fetch_assoc($result))
{
$cat_id = $row['cat_id'];
$cat_title = $row['cat_title'];
echo $cat_id . " " . $cat_title ."<br>";
}
This would output :
Here is another alternative answer to this issue. This extension method works quite well. This solves the issues of the string being shorter than the maximum length and also the maximum length being negative.
public static string Left( this string str, int length ) {
if (str == null)
return str;
return str.Substring(0, Math.Min(Math.Abs(length), str.Length));
}
Another solution would be to limit the length to be non-negative values, and just zero-out negative values.
public static string Left( this string str, int length ) {
if (str == null)
return str;
return str.Substring(0, Math.Min(Math.Max(0,length), str.Length));
}
If you are targeting more modern browsers, life can be very simple. try:
.elem{
height: 100vh;
}
if you need it at 50% of the page, replace 100 with 50.

i confirm doesn't work. i use phonegap 6.0.5 and cordova 6.2.0
Might want to try
keytool -import -trustcacerts -noprompt -keystore <full path to cacerts> -storepass changeit -alias $REMHOST -file $REMHOST.pem
i honestly have no idea where it puts your certificate if you just write cacerts
just give it a full path
It's not always just a default constraint that prevents from droping a column and sometimes indexes can also block you from droping the constraint. So I wrote a procedure that drops any index or constraint on a column and the column it self at the end.

DROP procedure ADM_delete_column;

Probably depending on the XML feed you may/may not need to use __toString()
; I had to use the __toString()
otherwise it is returning the string inside an SimpleXMLElement. Maybe I need to drill down the object further ...
Replace:
$authorization = "Bearer 080042cad6356ad5dc0a720c18b53b8e53d4c274"
with:
$authorization = "Authorization: Bearer 080042cad6356ad5dc0a720c18b53b8e53d4c274";
to make it a valid and working Authorization header.

I can think of a situation where postfix is slower than prefix increment:
Imagine a processor with register A
is used as accumulator and it's the only register used in many instructions (some small microcontrollers are actually like this).
Now imagine the following program and their translation into a hypothetical assembly:
Prefix increment:
a = ++b + c;
; increment b
LD A, [&b]
INC A
ST A, [&b]
; add with c
ADD A, [&c]
; store in a
ST A, [&a]
Postfix increment:
a = b++ + c;
; load b
LD A, [&b]
; add with c
ADD A, [&c]
; store in a
ST A, [&a]
; increment b
LD A, [&b]
INC A
ST A, [&b]
Note how the value of b
was forced to be reloaded. With prefix increment, the compiler can just increment the value and go ahead with using it, possibly avoid reloading it since the desired value is already in the register after the increment. However, with postfix increment, the compiler has to deal with two values, one the old and one the incremented value which as I show above results in one more memory access.
Of course, if the value of the increment is not used, such as a single i++;
statement, the compiler can (and does) simply generate an increment instruction regardless of postfix or prefix usage.
As a side note, I'd like to mention that an expression in which there is a b++
cannot simply be converted to one with ++b
without any additional effort (for example by adding a - 1
). So comparing the two if they are part of some expression is not really valid. Often, where you use b++
inside an expression you cannot use ++b
, so even if ++b
were potentially more efficient, it would simply be wrong. Exception is of course if the expression is begging for it (for example a = b++ + 1;
which can be changed to a = ++b;
).
You can do this:
DB::transaction(function() {
//
});
Everything inside the Closure executes within a transaction. If an exception occurs it will rollback automatically.
this could work for you.
using System.Linq;
DirectoryInfo info = new DirectoryInfo("PATH_TO_DIRECTORY_HERE");
FileInfo[] files = info.GetFiles().OrderBy(p => p.CreationTime).ToArray();
foreach (FileInfo file in files)
{
// DO Something...
}
Since 3.5, anything inherited from System.Collection.IEnumerable has the convenient extension method OfType available.
If your collection is from ICollection or IEnumerable, you can just do this:
List<ManagementObject> managementList = ManagementObjectCollection.OfType<ManagementObject>().ToList();
Can't find any way simpler. : )
I think this should be java.net.SocketException as its definition is stated for a TCP error.

Here is how to synchronize PHP (>=5.3) and MySQL timezones per session and user settings. Put this where it runs when you need set and synchronized timezones.
date_default_timezone_set($my_timezone);
$n = new \DateTime();
$h = $n->getOffset()/3600;
$i = 60*($h-floor($h));
$offset = sprintf('%+d:%02d', $h, $i);
$this->db->query("SET time_zone='$offset'");
Where $my_timezone is one in the list of PHP timezones: http://www.php.net/manual/en/timezones.php
The PHP timezone has to be converted into the hour and minute offset for MySQL. That's what lines 1-4 do.
Acknowledging the fact that the asker specifically requested jQuery and that the answer selected is correct, it should be noted that this problem doesn't actually need jQuery per say. If one desires to solve this problem without it, one can simply set the onClick
attribute of the checkboxes that he or she wants to add additional functionality to, like so:
HTML:
<form id="myform">
<input type="checkbox" name="check1" value="check1" onClick="cbChanged(this);">
<input type="checkbox" name="check2" value="check2" onClick="cbChanged(this);">
</form>
javascript:
function cbChanged(checkboxElem) {
if (checkboxElem.checked) {
// Do something special
} else {
// Do something else
}
}
Fiddle: http://jsfiddle.net/Y9f66/1/
Code coverage is great, but functionality coverage is even better. I don't believe in covering every single line I write. But I do believe in writing 100% test coverage of all the functionality I want to provide (even for the extra cool features I came with myself and which were not discussed during the meetings).
I don't care if I would have code which is not covered in tests, but I would care if I would refactor my code and end up having a different behaviour. Therefore, 100% functionality coverage is my only target.
This is almost certainly performance reasons. For example, imagine a parser that goes through a 500k ByteBuffer containing strings.
There are 3 approaches to returning the string content:
Build a String[] at parse time, one character at a time. This will take a noticeable amount of time. We can use == instead of .equals to compare cached references.
Build an int[] with offsets at parse time, then dynamically build String when a get() happens. Each String will be a new object, so no caching returned values and using ==
Build a CharSequence[] at parse time. Since no new data is stored (other than offsets into the byte buffer), the parsing is much lower that #1. At get time, we don't need to build a String, so get performance is equal to #1 (much better than #2), as we're only returning a reference to an existing object.
In addition to the processing gains you get using CharSequence, you also reduce the memory footprint by not duplicating data. For example, if you have a buffer containing 3 paragraphs of text, and want to return either all 3 or a single paragraph, you need 4 Strings to represent this. Using CharSequence you only need 1 buffer with the data, and 4 instances of a CharSequence implementation that tracks the start and length.
Historically, the first extensions used for C++ were .c
and .h
, exactly like for C. This caused practical problems, especially the .c
which didn't allow build systems to easily differentiate C++ and C files.
Unix, on which C++ has been developed, has case sensitive file systems. So some used .C
for C++ files. Other used .c++
, .cc
and .cxx
. .C
and .c++
have the problem that they aren't available on other file systems and their use quickly dropped. DOS and Windows C++ compilers tended to use .cpp
, and some of them make the choice difficult, if not impossible, to configure. Portability consideration made that choice the most common, even outside MS-Windows.
Headers have used the corresponding .H
, .h++
, .hh
, .hxx
and .hpp
. But unlike the main files, .h
remains to this day a popular choice for C++ even with the disadvantage that it doesn't allow to know if the header can be included in C context or not. Standard headers now have no extension at all.
Additionally, some are using .ii
, .ixx
, .ipp
, .inl
for headers providing inline definitions and .txx
, .tpp
and .tpl
for template definitions. Those are either included in the headers providing the definition, or manually in the contexts where they are needed.
Compilers and tools usually don't care about what extensions are used, but using an extension that they associate with C++ prevents the need to track out how to configure them so they correctly recognize the language used.
2017 edit: the experimental module support of Visual Studio recognize .ixx
as a default extension for module interfaces, clang++ is recognizing .c++m
, .cppm
and .cxxm
for the same purpose.
I'm sorry to answer an old post but I was looking for a solution and came across this question.
There are many workarounds for this issue to still display the scrollbar, like giving the container a 100% height and an overflow-y: scroll
styling.
In my case I just created a div with a scrollbar which I display while adding overflow: hidden
to the body:
function disableScroll() {
document.getElementById('scrollbar').style.display = 'block';
document.body.style.overflow = 'hidden';
}
The element scrollbar must have this styles:
overflow-y: scroll; top: 0; right: 0; display: none; height: 100%; position: fixed;
This shows a grey scrollbar, hope it helps future visitors.
If your Postgres was working and suddenly you encountered with this error, my problem was resolved just by restarting Postgres service or container.
The constant values (uses in fixtures or assertions) should be initialized in their declarations and final
(as never change)
the object under test should be initialized in the setup method because we may set things on. Of course we may not set something now but we could set it later. Instantiating in the init method would ease the changes.
dependencies of the object under test if these are mocked, should not even be instantiated by yourself : today the mock frameworks can instantiate it by reflection.
A test without dependency to mock could look like :
public class SomeTest {
Some some; //instance under test
static final String GENERIC_ID = "123";
static final String PREFIX_URL_WS = "http://foo.com/ws";
@Before
public void beforeEach() {
some = new Some(new Foo(), new Bar());
}
@Test
public void populateList()
...
}
}
A test with dependencies to isolate could look like :
@RunWith(org.mockito.runners.MockitoJUnitRunner.class)
public class SomeTest {
Some some; //instance under test
static final String GENERIC_ID = "123";
static final String PREFIX_URL_WS = "http://foo.com/ws";
@Mock
Foo fooMock;
@Mock
Bar barMock;
@Before
public void beforeEach() {
some = new Some(fooMock, barMock);
}
@Test
public void populateList()
...
}
}
