Your model is null
because the way you're supplying the inputs to your form means the model binder has no way to distinguish between the elements. Right now, this code:
@foreach (var planVM in Model)
{
@Html.Partial("_partialView", planVM)
}
is not supplying any kind of index to those items. So it would repeatedly generate HTML output like this:
<input type="hidden" name="yourmodelprefix.PlanID" />
<input type="hidden" name="yourmodelprefix.CurrentPlan" />
<input type="checkbox" name="yourmodelprefix.ShouldCompare" />
However, as you're wanting to bind to a collection, you need your form elements to be named with an index, such as:
<input type="hidden" name="yourmodelprefix[0].PlanID" />
<input type="hidden" name="yourmodelprefix[0].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[0].ShouldCompare" />
<input type="hidden" name="yourmodelprefix[1].PlanID" />
<input type="hidden" name="yourmodelprefix[1].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[1].ShouldCompare" />
That index is what enables the model binder to associate the separate pieces of data, allowing it to construct the correct model. So here's what I'd suggest you do to fix it. Rather than looping over your collection, using a partial view, leverage the power of templates instead. Here's the steps you'd need to follow:
EditorTemplates
folder inside your view's current folder (e.g. if your view is Home\Index.cshtml
, create the folder Home\EditorTemplates
).PlanCompareViewModel.cshtml
.Now, everything you have in your partial view wants to go in that template:
@model PlanCompareViewModel
<div>
@Html.HiddenFor(p => p.PlanID)
@Html.HiddenFor(p => p.CurrentPlan)
@Html.CheckBoxFor(p => p.ShouldCompare)
<input type="submit" value="Compare"/>
</div>
Finally, your parent view is simplified to this:
@model IEnumerable<PlanCompareViewModel>
@using (Html.BeginForm("ComparePlans", "Plans", FormMethod.Post, new { id = "compareForm" }))
{
<div>
@Html.EditorForModel()
</div>
}
DisplayTemplates
and EditorTemplates
are smart enough to know when they are handling collections. That means they will automatically generate the correct names, including indices, for your form elements so that you can correctly model bind to a collection.
@Html.Partial("_Header", new ViewDataDictionary { { "HeaderName", "User Management" }, { "TitleName", "List Of Users" } })
or
@{Html.RenderPartial("_Header", new ViewDataDictionary { { "HeaderName", "User Management" }, { "TitleName", "List Of Users" } });}
Partial Page(_Header):
<div class="row titleBlock">
<h1>@ViewData["HeaderName"].ToString()</h1>
<h5>@ViewData["TitleName"].ToString()</h5>
</div>
You need to create a view model. Something like this should do...
public class FullNameViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
public FullNameViewModel() { }
public FullNameViewModel(string firstName, string lastName)
{
this.FirstName = firstName;
this.LastName = lastName;
}
}
then from your action result pass the model
return View("FullName", new FullNameViewModel("John", "Doe"));
and you will be able to access @Model.FirstName
and @Model.LastName
accordingly.
Small tweek to the above
@Ajax.ActionLink(
"Click Here to Load the Partial View",
"ActionName",
"ControlerName",
null,
new AjaxOptions { UpdateTargetId = "toUpdate" }
)
<div id="toUpdate"></div>
function getCaretPosition() {
var x = 0;
var y = 0;
var sel = window.getSelection();
if(sel.rangeCount) {
var range = sel.getRangeAt(0).cloneRange();
if(range.getClientRects()) {
range.collapse(true);
var rect = range.getClientRects()[0];
if(rect) {
y = rect.top;
x = rect.left;
}
}
}
return {
x: x,
y: y
};
}
That would work depending on what client.get does when passed undefined as its first parameter.
Something like this would be safer:
app.get('/:key?', function(req, res, next) {
var key = req.params.key;
if (!key) {
next();
return;
}
client.get(key, function(err, reply) {
if(client.get(reply)) {
res.redirect(reply);
}
else {
res.render('index', {
link: null
});
}
});
});
There's no problem in calling next() inside the callback.
According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.
I don't consider the use of VOLUME good in any case, except if you are creating an image for yourself and no one else is going to use it.
I was impacted negatively due to VOLUME exposed in base images that I extended and only came up to know about the problem after the image was already running, like wordpress that declares the /var/www/html
folder as a VOLUME, and this meant that any files added or changed during the build stage aren't considered, and live changes persist, even if you don't know. There is an ugly workaround to define web directory in another place, but this is just a bad solution to a much simpler one: just remove the VOLUME directive.
You can achieve the intent of volume easily using the -v
option, this not only make it clear what will be the volumes of the container (without having to take a look at the Dockerfile and parent Dockerfiles), but this also gives the consumer the option to use the volume or not.
It's also bad to use VOLUMES due to the following reasons, as said by this answer:
However, the VOLUME instruction does come at a cost.
- Users might not be aware of the unnamed volumes being created, and continuing to take up storage space on their Docker host after containers are removed.
- There is no way to remove a volume declared in a Dockerfile. Downstream images cannot add data to paths where volumes exist.
The latter issue results in problems like these.
Having the option to undeclare a volume would help, but only if you know the volumes defined in the dockerfile that generated the image (and the parent dockerfiles!). Furthermore, a VOLUME could be added in newer versions of a Dockerfile and break things unexpectedly for the consumers of the image.
Another good explanation (about the oracle image having VOLUME, which was removed): https://github.com/oracle/docker-images/issues/640#issuecomment-412647328
More cases in which VOLUME broke stuff for people:
A pull request to add options to reset properties the parent image (including VOLUME), was closed and is being discussed here (and you can see several cases of people affected adversely due to volumes defined in dockerfiles), which has a comment with a good explanation against VOLUME:
Using VOLUME in the Dockerfile is worthless. If a user needs persistence, they will be sure to provide a volume mapping when running the specified container. It was very hard to track down that my issue of not being able to set a directory's ownership (/var/lib/influxdb) was due to the VOLUME declaration in InfluxDB's Dockerfile. Without an UNVOLUME type of option, or getting rid of it altogether, I am unable to change anything related to the specified folder. This is less than ideal, especially when you are security-aware and desire to specify a certain UID the image should be ran as, in order to avoid a random user, with more permissions than necessary, running software on your host.
The only good thing I can see about VOLUME is about documentation, and I would consider it good if it only did that (without any side effects).
TL;DR
I consider that the best use of VOLUME is to be deprecated.
It is not possible in on step or you need to keep the reference to the array. If you can change the reference this can help:
String[] n = new String[]{"google","microsoft","apple"};
final List<String> list = new ArrayList<String>();
Collections.addAll(list, n);
list.remove("apple");
n = list.toArray(new String[list.size()]);
I not recommend the following but if you worry about performance:
String[] n = new String[]{"google","microsoft","apple"};
final String[] n2 = new String[2];
System.arraycopy(n, 0, n2, 0, n2.length);
for (int i = 0, j = 0; i < n.length; i++)
{
if (!n[i].equals("apple"))
{
n2[j] = n[i];
j++;
}
}
I not recommend it because the code is a lot more difficult to read and maintain.
As you can see, 01/01/1970 returns 0, which means it is the lowest possible date.
new Date('1970-01-01Z00:00:00:000') //returns Thu Jan 01 1970 01:00:00 GMT+0100 (Central European Standard Time)
new Date('1970-01-01Z00:00:00:000').getTime() //returns 0
new Date('1970-01-01Z00:00:00:001').getTime() //returns 1
Simple solution:
git init
git add =A
git commit -m "your commit"
git push -u origin master
if you want add folder to existing repo ..then add folder to local project code
git rm --cached ./folderName
git add ./folderName
after that
git status
git commit -m "your commit"
git push -u origin master
Your code is correct. Kindly mark small correction.

return false;
}

return super.onOptionsItemSelected(item);
}
}
The use of the deprecated new Buffer()
constructor (i.E. as used by Yarn) can cause deprecation warnings. Therefore one should NOT use the deprecated/unsafe Buffer constructor.
According to the deprecation warning new Buffer()
should be replaced with one of:
Buffer.alloc()
Buffer.allocUnsafe()
or Buffer.from()
Another option in order to avoid this issue would be using the safe-buffer package instead.
You can also try (when using yarn..):
yarn global add yarn
as mentioned here: Link
Another suggestion from the comments (thx to gkiely): self-update
Note: self-update is not available. See policies for enforcing versions within a project
In order to update your version of Yarn, run
curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

As olt already pointed out, Image.paste
doesn't work properly, when source and destination both contain alpha.
Consider the following scenario:
Two test images, both contain alpha:
layer1 = Image.open("layer1.png")
layer2 = Image.open("layer2.png")
Compositing image using Image.paste
like so:
final1 = Image.new("RGBA", layer1.size)
final1.paste(layer1, (0,0), layer1)
final1.paste(layer2, (0,0), layer2)
produces the following image (the alpha part of the overlayed red pixels is completely taken from the 2nd layer. The pixels are not blended correctly):
Compositing image using Image.alpha_composite
like so:
final2 = Image.new("RGBA", layer1.size)
final2 = Image.alpha_composite(final2, layer1)
final2 = Image.alpha_composite(final2, layer2)
produces the following (correct) image:
jus do this import { shallow, mount } from "enzyme";
const store = mockStore({
startup: { complete: false }
});
describe("==== Testing App ======", () => {
const setUpFn = props => {
return mount(
<Provider store={store}>
<App />
</Provider>
);
};
let wrapper;
beforeEach(() => {
wrapper = setUpFn();
});
I was using a virtual environment on Ubuntu 18.04, and since I only wanted to install it as a client, I only had to do:
sudo apt install libpq-dev
pip install psycopg2
And installed without problems. Of course, you can use the binary as other answers said, but I preferred this solution since it was stated in a requirements.txt file.

There is a modern port for this Turbo C graphics interface, it's called WinBGIM, which emulates BGI graphics under MinGW/GCC.
I haven't it tried but it looks promising. For example initgraph creates a window, and from this point you can draw into that window using the good old functions, at the end closegraph deletes the window. It also has some more advanced extensions (eg. mouse handling and double buffering).
When I first moved from DOS programming to Windows I didn't have internet, and I begged for something simple like this. But at the end I had to learn how to create windows and how to handle events and use device contexts from the offline help of the Windows SDK.

You can use momentjs
to implement date-time filter in angularjs.
For example:
angular.module('myApp')
.filter('formatDateTime', function ($filter) {
return function (date, format) {
if (date) {
return moment(Number(date)).format(format || "DD/MM/YYYY h:mm A");
}
else
return "";
};
});
Where date is in time stamp format.
A solution for this problem with a filtered ngRepeat could have been with Mutation events, but they are deprecated (without immediate replacement).
Then I thought of another easy one:
app.directive('filtered',function($timeout) {
return {
restrict: 'A',link: function (scope,element,attr) {
var elm = element[0]
,nodePrototype = Node.prototype
,timeout
,slice = Array.prototype.slice
;
elm.insertBefore = alt.bind(null,nodePrototype.insertBefore);
elm.removeChild = alt.bind(null,nodePrototype.removeChild);
function alt(fn){
fn.apply(elm,slice.call(arguments,1));
timeout&&$timeout.cancel(timeout);
timeout = $timeout(altDone);
}
function altDone(){
timeout = null;
console.log('Filtered! ...fire an event or something');
}
}
};
});
This hooks into the Node.prototype methods of the parent element with a one-tick $timeout to watch for successive modifications.
It works mostly correct but I did get some cases where the altDone would be called twice.
Again... add this directive to the parent of the ngRepeat.

To read binary ASCII characters with great speed using only your head:
Letters start with leading bits 01. Bit 3 is on (1) for lower case, off (0) for capitals. Scan the following bits 4–8 for the first that is on, and select the starting letter from the same index in this string: “PHDBA” (think P.H.D., Bachelors in Arts). E.g. 1xxxx = P, 01xxx = H, etc. Then convert the remaining bits to an integer value (e.g. 010 = 2), and count that many letters up from your starting letter. E.g. 01001010 => H+2 = J.

Why were you using an Hashmap if what you wanted was to put it into a JSONObject?
EDIT: As per http://www.json.org/javadoc/org/json/JSONArray.html
EDIT2: On the JSONObject method used, I'm following the code available at: https://github.com/stleary/JSON-java/blob/master/JSONObject.java#L2327 , that method is not deprecated.
We're storing a string representation of the JSONObject, not the JSONObject itself
Try like this:
$url = 'url_to_post';
// this is only part of the data you need to sen
$customer_data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" => "Mother","last_name" => "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
// As per your API, the customer data should be structured this way
$data = array("customer" => $customer_data);
// And then encoded as a json string
$data_string = json_encode($data);
$ch=curl_init($url);
curl_setopt_array($ch, array(
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $data_string,
CURLOPT_HEADER => true,
CURLOPT_HTTPHEADER => array('Content-Type:application/json', 'Content-Length: ' . strlen($data_string)))
));
$result = curl_exec($ch);
curl_close($ch);
The key thing you've forgotten was to json_encode your data. But you also may find it convenient to use curl_setopt_array to set all curl options at once by passing an array.
Try this using regular expression:
import re
data['result'] = data['result'].map(lambda x: re.sub('[-+A-Za-z]',x)
It seems you can change the colour of the checkbox in grayscale by using CSS only.

[ ]
defines a character class. So every character you set there, will match. [012]
will match 0
or 1
or 2
and [0-2]
behaves the same.
What you want is groupings to define a or-statement. Use (s|season)
for your issue.
Btw. you have to watch out. Metacharacters in normal regex (or inside a grouping) are different from character class. A character class is like a sub-language. [$A]
will only match $
or A
, nothing else. No escaping here for the dollar.
Sometime we need to compile one single file out of thousand files to fix the problem. In such a case, One can create same folder structure like class path, decompile the file into java or copy java file from source code. Make required changes, compile one particular file into class with all dependency/classes in place and finally replace the class file. Finally restart the container. Once war is exploded file will not be replaced.
I struggled with this, too. My specific setup is: Your host.ini (with the modern names):
[test3]
test3-1 ansible_host=abc.def.ghi.pqr ansible_port=1212
test3-2 ansible_host=abc.def.ghi.stu ansible_port=1212
plus a play fill_file.yml
---
- remote_user: ec2-user
hosts: test3
tasks:
- name: fill file
template:
src: file.j2
dest: filled_file.txt
plus a template file.j2 , like
{% for host in groups['test3'] %}
{{ hostvars[host].ansible_host }}
{% endfor %}
This worked for me, the result is
abc.def.ghi.pqr
abc.def.ghi.stu
I have to admit it's ansible 2.7, not 2.1. The template is a variation of an example in https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html.
The accepted answer didn't work in my setup. With a template
{{ hostvars['test3'].ansible_host }}
my play fails with "AnsibleUndefinedVariable: \"hostvars['test3']\" is undefined" .
Remark: I tried some variations, but failed, occasionally with "ansible.vars.hostvars.HostVars object has no element "; Some of this might be explained by what they say. in https://github.com/ansible/ansible/issues/13343#issuecomment-160992631
hostvars emulates a dictionary [...]. hostvars is also lazily loaded
POST allows for an arbitrary length of data to be sent to a server, but there are limitations based on timeouts/bandwidth etc.
I think basically, it's safer to assume that it's not okay to send lots of data.
The simplest way to do this is to install Json.NET
from nuget and add the [JsonIgnore]
attribute to the virtual property in the class, for example:
public string Name { get; set; }
public string Description { get; set; }
public Nullable<int> Project_ID { get; set; }
[JsonIgnore]
public virtual Project Project { get; set; }
Although these days, I create a model with only the properties I want passed through so it's lighter, doesn't include unwanted collections, and I don't lose my changes when I rebuild the generated files...
The following code works:
@Override
protected synchronized void onDraw(Canvas canvas)
{
int stars = getNumStars();
float rating = getRating();
try
{
bitmapWidth = getWidth() / stars;
}
catch (Exception e)
{
bitmapWidth = getWidth();
}
float x = 0;
for (int i = 0; i < stars; i++)
{
Bitmap bitmap;
Resources res = getResources();
Paint paint = new Paint();
if ((int) rating > i)
{
bitmap = BitmapFactory.decodeResource(res, starColor);
}
else
{
bitmap = BitmapFactory.decodeResource(res, starDefault);
}
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, getHeight(), getHeight(), true);
canvas.drawBitmap(scaled, x, 0, paint);
canvas.save();
x += bitmapWidth;
}
super.onDraw(canvas);
}
Your code and schema are OK. You probably trying on previous version of table.
http://sqlfiddle.com/#!2/9dc64/1/0
Your table even has no UNIQUE, so that error is impossible on that table.
Backup data from that table, drop it and re-create.
Maybe you tried to run that CREATE TABLE IF NOT EXIST
. It was not created, you have old version, but there was no error because of IF NOT EXIST
.
You may run SQL like this to see current table structure:
DESCRIBE my_table;
Edit - added later:
Try to run this:
DROP TABLE `my_table`; --make backup - it deletes table
CREATE TABLE `my_table` (
`number` int(11) NOT NULL,
`name` varchar(50) NOT NULL,
`money` int(11) NOT NULL,
PRIMARY KEY (`number`,`name`),
UNIQUE (`number`, `name`) --added unique on 2 rows
) ENGINE=MyISAM;
The application/x-www-form-urlencoded
Content-type header is not needed. Unless the request handler expects the parameters coming from request body. Try it out:
curl -X DELETE "http://localhost:5000/locations?id=3"
or
curl -X GET "http://localhost:5000/locations?id=3"
If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user
, picked from your example), then the syntax is quite simple:
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin('a.user', 'u')
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
Since you are applying a condition on the joined result here, using a LEFT JOIN
or simply JOIN
is the same.
If no association is available, then the query looks like following
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin(
'User\Entity\User',
'u',
\Doctrine\ORM\Query\Expr\Join::WITH,
'a.user = u.id'
)
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
This will produce a resultset that looks like following:
array(
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
// ...
)
Sometimes if you are making a target via make files double check that all c files are named correctly with correct file structure.
Both proposed possibilities (std::swap
and std::iter_swap
) work, they just have a slightly different syntax.
Let's swap a vector's first and second element, v[0]
and v[1]
.
We can swap based on the objects contents:
std::swap(v[0],v[1]);
Or swap based on the underlying iterator:
std::iter_swap(v.begin(),v.begin()+1);
Try it:
int main() {
int arr[] = {1,2,3,4,5,6,7,8,9};
std::vector<int> * v = new std::vector<int>(arr, arr + sizeof(arr) / sizeof(arr[0]));
// put one of the above swap lines here
// ..
for (std::vector<int>::iterator i=v->begin(); i!=v->end(); i++)
std::cout << *i << " ";
std::cout << std::endl;
}
Both times you get the first two elements swapped:
2 1 3 4 5 6 7 8 9
Because UTF-8 is multibyte and there is no char corresponding to your combination of \xe9
plus following space.
Why should it succeed in both utf-8 and latin-1?
Here how the same sentence should be in utf-8:
>>> o.decode('latin-1').encode("utf-8")
'a test of \xc3\xa9 char'
This is an issue that can happen in Android Studio if you modify Project Structure Modules. In this case you may need to add the dependencies again. In a text editor edit the 'build.gradle' file to include the required dependencies:
dependencies {
compile 'com.android.support:appcompat-v7:+'
compile fileTree(dir: 'libs', include: ['*.jar'])
}
This should update your '{your_project_name}.iml' file with lib components:
<orderEntry type="library" exported="" name="appcompat-v7-19.0.1" level="project" />

I have opened an issue requesting this functionality for Google Guava. Perhaps someone would care to support it.
Just do:
echo substr($string, 0, -3);
You don't need to use a strlen
call, since, as noted in the substr docs:
If length is given and is negative, then that many characters will be omitted from the end of string
You can Do this
var array = [];
// assigning values to corresponding keys
array[0] = "Main page";
array[1] = "Guide page";
array[2] = "Articles page";
array[3] = "Forum board";
array.forEach(value => {
console.log(value)
})
function download(text, name, type) {_x000D_
var a = document.getElementById("a");_x000D_
var file = new Blob([text], {type: type});_x000D_
a.href = URL.createObjectURL(file);_x000D_
a.download = name;_x000D_
}
_x000D_
<a href="" id="a">click here to download your file</a>_x000D_
<button onclick="download('file text', 'myfilename.txt', 'text/plain')">Create file</button>
_x000D_
And you would then download the file by putting the download attribute on the anchor tag.
The reason I like this better than creating a data url is that you don't have to make a big long url, you can just generate a temporary url.
Here is another solution I wrote in C# to auto startup native node server or pm2 server on Windows.
Logarithmic running time (O(log n)
) essentially means that the running time grows in proportion to the logarithm of the input size - as an example, if 10 items takes at most some amount of time x
, and 100 items takes at most, say, 2x
, and 10,000 items takes at most 4x
, then it's looking like an O(log n)
time complexity.
I know this question is 4 years old, but I have a couple different options:
tar --to-command grep
The following line will look in example.tgz
for PATTERN
. This is similar to @Jester's example, but I couldn't get his pattern matching to work.
tar xzf example.tgz --to-command 'grep --label="$TAR_FILENAME" -H PATTERN ; true'
tar -tzf
The second option is using tar -tzf
to list the files, then go through them with grep
. You can create a function to use it over and over:
targrep () {
for i in $(tar -tzf "$1"); do
results=$(tar -Oxzf "$1" "$i" | grep --label="$i" -H "$2")
echo "$results"
done
}
Usage:
targrep example.tar.gz "pattern"
However, avpicture_get_size is defined.
No, as the header (<libavcodec/avcodec.h>
) just declares it.
The definition is in the library itself.
So you might like to add the linker option to link libavcodec
when invoking gcc:
-lavcodec
Please also note that libraries need to be specified on the command line after the files needing them:
gcc -I$HOME/ffmpeg/include program.c -lavcodec
Not like this:
gcc -lavcodec -I$HOME/ffmpeg/include program.c
Referring to Wyzard's comment, the complete command might look like this:
gcc -I$HOME/ffmpeg/include program.c -L$HOME/ffmpeg/lib -lavcodec
For libraries not stored in the linkers standard location the option -L
specifies an additional search path to lookup libraries specified using the -l
option, that is libavcodec.x.y.z
in this case.
For a detailed reference on GCC's linker option, please read here.

It seems working :
HTML :
<input type='text' id="pointspossible"/>
<input type='text' id="pointsgiven" />
<input type='text' id="pointsperc" disabled/>
JavaScript :
$(function(){
$('#pointspossible').on('input', function() {
calculate();
});
$('#pointsgiven').on('input', function() {
calculate();
});
function calculate(){
var pPos = parseInt($('#pointspossible').val());
var pEarned = parseInt($('#pointsgiven').val());
var perc="";
if(isNaN(pPos) || isNaN(pEarned)){
perc=" ";
}else{
perc = ((pEarned/pPos) * 100).toFixed(3);
}
$('#pointsperc').val(perc);
}
});
You can use radio groups to achieve that functionality:
<input type="radio" name="choice" value="yes" />Yes
<input type="radio" name="choice" value="No" />No
<input type="radio" name="choice" value="null" />null
You're looking for absolute value, mate. Math.abs(-5)
returns 5...
Have you checked/changed the updatePolicy settings for your repositories in your settings.xml
.
This element specifies how often updates should attempt to occur. Maven will compare the local POM's timestamp (stored in a repository's maven-metadata file) to the remote. The choices are: always, daily (default), interval:X (where X is an integer in minutes) or never.
Try to set it to always
.
It's an encoding error - so if it's a unicode string, this ought to fix it:
text.encode("windows-1252").decode("utf-8")
If it's a plain string, you'll need an extra step:
text.decode("utf-8").encode("windows-1252").decode("utf-8")
Both of these will give you a unicode string.
By the way - to discover how a piece of text like this has been mangled due to encoding issues, you can use chardet:
>>> import chardet
>>> chardet.detect(u"And the Hip’s coming, too")
{'confidence': 0.5, 'encoding': 'windows-1252'}
Probably something like this:
original_list = dictionary.get('C1')
new_list = []
for item in original_list:
new_list.append(item+10)
dictionary['C1'] = new_list
Refactoring the above methods and showing with the use:
private String[] languages = {"pt", "en", "es"};
private Integer indexOf(String[] arr, String str){
for (int i = 0; i < arr.length; i++)
if(arr[i].equals(str)) return i;
return -1;
}
indexOf(languages, "en")
I think the "best answer" above, albeit programmatically accurate, does not actually answer the question posed. the question asks how to change the pointer in the mouseover event. I see posts about how one may have an error somewhere is not answering the question. In the accepted answer, the mouseover event is blank (onmouseover=""
) and the style option, instead, is included. Baffling why this was done.
There may be nothing wrong with the inquirer's link. consider the following html:
<a id=test_link onclick="alert('kinda neat);">Click ME!</a>
When a user mouse's over this link, the pointer will not change to a hand...instead, the pointer will behave like it's hovering over normal text. One might not want this...and so, the mouse pointer needs to be told to change.
the answer being sought for is this (which was posted by another):
<a id=test_link onclick="alert('Nice!');"
onmouseover="this.style.cursor='pointer';">Click ME!</a>
However, this is ... a nightmare if you have lots of these, or use this kind of thing all over the place and decide to make some kind of a change or run into a bug. better to make a CSS class for it:
a.lendhand {
cursor: pointer;
}
then:
<a class=lendhand onclick="alert('hand is lent!');">Click ME!</a>
there are many other ways which would be, arguably, better than this method. DIVs, BUTTONs, IMGs, etc might prove more useful. I see no harm in using <a>...</a>
, though.

Visitor Pattern as the same underground implementation to Aspect Object programming..
For example if you define a new operation without changing the classes of the elements on which it operates
You could look at using Lattice. In this example I have defined a grid over which I want to plot z~x,y. It looks something like this. Note that most of the code is just building a 3D shape that I plot using the wireframe function.
The variables "b" and "s" could be x or y.
require(lattice)
# begin generating my 3D shape
b <- seq(from=0, to=20,by=0.5)
s <- seq(from=0, to=20,by=0.5)
payoff <- expand.grid(b=b,s=s)
payoff$payoff <- payoff$b - payoff$s
payoff$payoff[payoff$payoff < -1] <- -1
# end generating my 3D shape
wireframe(payoff ~ s * b, payoff, shade = TRUE, aspect = c(1, 1),
light.source = c(10,10,10), main = "Study 1",
scales = list(z.ticks=5,arrows=FALSE, col="black", font=10, tck=0.5),
screen = list(z = 40, x = -75, y = 0))
function relativepath($to){
$a=explode("/",$_SERVER["PHP_SELF"] );
$index= array_search("$to",$a);
$str="";
for ($i = 0; $i < count($a)-$index-2; $i++) {
$str.= "../";
}
return $str;
}
Here is the best solution i made about that, you just need to specify at which level you want to stop, but the problem is that you have to use this folder name one time.
At least at STS (SpringSource Tool Suite) groups are numbered starting form 0, so replace string will be
replace: ((TypeName)$0)
It is important to understand that the transaction buffer is limited to 1 MB, regardless of device capabilities or app. This buffer is used with every API calls you make and is shared amongst all transactions an app is currently running.
I believe it also holds some specific object like parcels and such (Parcel.obtain())
, so it's important to always match every obtain()
with a recycle()
.
This error can easily happen on API calls returning a lot of data, even though the returned data is less than 1 MB (if other transactions are still running).
For example, the PackageManager.getInstalledApplication()
call returns a list of all apps installed. Adding specific flags allows to retrieve a lot of extra data. Doing so is likely to fail, so it's recommended not to retrieve any extra data and retrieve those on a per-app basis.
However the call may still fail, so it's important to surround it with a catch
and be able to retry if necessary.
As far as I know, there's no work-around to such issue except retrying and making sure to retrieve as little information as possible.
If you want to scan to the end of the string (stripping out a newline if there), just use:
char *x = "19 cool kid";
sscanf (x, "%d %[^\n]", &age, buffer);
That's because %s
only matches non-whitespace characters and will stop on the first whitespace it finds. The %[^\n]
format specifier will match every character that's not (because of ^
) in the selection given (which is a newline). In other words, it will match any other character.
Keep in mind that you should have allocated enough space in your buffer to take the string since you cannot be sure how much will be read (a good reason to stay away from scanf/fscanf
unless you use specific field widths).
You could do that with:
char *x = "19 cool kid";
char *buffer = malloc (strlen (x) + 1);
sscanf (x, "%d %[^\n]", &age, buffer);
(you don't need * sizeof(char)
since that's always 1 by definition).
A simple expansion that doesn't require the datetime
module and isn't handicapped like some other solutions is to use simple string replacement like so:
import logging
import time
class MyFormatter(logging.Formatter):
def formatTime(self, record, datefmt=None):
ct = self.converter(record.created)
if datefmt:
if "%F" in datefmt:
msec = "%03d" % record.msecs
datefmt = datefmt.replace("%F", msec)
s = time.strftime(datefmt, ct)
else:
t = time.strftime("%Y-%m-%d %H:%M:%S", ct)
s = "%s,%03d" % (t, record.msecs)
return s
This way a date format can be written however you want, even allowing for region differences, by using %F
for milliseconds. For example:
log = logging.getLogger(__name__)
log.setLevel(logging.INFO)
sh = logging.StreamHandler()
log.addHandler(sh)
fm = MyFormatter(fmt='%(asctime)s-%(levelname)s-%(message)s',datefmt='%H:%M:%S.%F')
sh.setFormatter(fm)
log.info("Foo, Bar, Baz")
# 03:26:33.757-INFO-Foo, Bar, Baz
This can also be done in the GUI:
If your page is deeply pathed or might move around and your JS script is at "~/JS/Registration.js" of your web folder, you can try the following:
<script src='<%=ResolveClientUrl("~/JS/Registration.js") %>'
type="text/javascript"></script>
Because I never found a solution to this I decided to upgrade my LAMP environment. I went to Ubuntu 10.4 LTS with PHP 5.3.x. This seems to have stopped the problem for me.
You'd probably want to look at the HTML to see if you can find strings that are unique and near your text, then you can use line/char-offsets to get to the data.
Could be awkward in Java, if there aren't any XML classes similar to the ones found in System.XML.Linq
in C#.
Similar issue where I was getting permissions failed. On my setup, I SSH in only. So What I did to correct the issue was
sudo MySQL
SELECT User, Host FROM mysql.user WHERE Host <> '%';
MariaDB [(none)]> SELECT User, Host FROM mysql.user WHERE Host <> '%';
+-------+-------------+
| User | Host |
+-------+-------------+
| root | 169.254.0.% |
| foo | 192.168.0.% |
| bar | 192.168.0.% |
+-------+-------------+
4 rows in set (0.00 sec)
I need these users moved to 'localhost'. So I issued the following:
UPDATE mysql.user SET host = 'localhost' WHERE user = 'foo';
UPDATE mysql.user SET host = 'localhost' WHERE user = 'bar';
Run SELECT User, Host FROM mysql.user WHERE Host <> '%'; again and we see:
MariaDB [(none)]> SELECT User, Host FROM mysql.user WHERE Host <> '%';
+-------+-------------+
| User | Host |
+-------+-------------+
| root | 169.254.0.% |
| foo | localhost |
| bar | localhost |
+-------+-------------+
4 rows in set (0.00 sec)
And then I was able to work normally again. Hope that helps someone.
$ mysql -u foo -p

SELECT * FROM my_table where DATE(start_date) > '2011-01-01';
I wanted to remove all tags except for those that match a pattern so that I could delete all but the last couple of months of production tags, here's what I used to great success:
Delete All Remote Tags & Exclude Expression From Delete
git tag -l | grep -P '^(?!Production-2017-0[89])' | xargs -n 1 git push --delete origin
Delete All Local Tags & Exclude Expression From Delete
git tag -l | grep -P '^(?!Production-2017-0[89])' | xargs git tag -d
Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.
For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".
Visual Aid on Freeze Panes in Excel 2010 - http://www.dummies.com/how-to/content/how-to-freeze-panes-in-an-excel-2010-worksheet.html
Microsoft Reference Guide (More Complicated, but resourceful none the less) - http://office.microsoft.com/en-us/excel-help/freeze-or-lock-rows-and-columns-HP010342542.aspx
You can do this in QtDesigner. Just click on your button then go to icon property and then choose your image file.
These methods will work, but without an explicit id as a PK then determining which rows to delete could be a problem. The bounce out into a temp table delete from original and re-insert without the dupes seems to be the simplest.
Perhaps you're asking about keeping such things going...
Of course you'll invoke a full table scan for the queries and if the table containing the scores that need to be tallied (aggregations) is large you might want a better performing solution, you can create a secondary table and use rules, such as on insert
- you might look into it.
Not all RDBMS engines have rules, though!
See if this is what you want to do:
@echo off
for /f "delims=" %%a in ('wmic OS Get localdatetime ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set HH=%dt:~8,2%
set Min=%dt:~10,2%
set Sec=%dt:~12,2%
set stamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%
copy "F:\Folder\File 1.xlsx" "F:\Folder\Archive\File 1 - %stamp%.xlsx"
@html.label and @html.textbox are use when you want bind it to your model in a easy way...which cannot be achieve by input etc. in one line
You can just go with:
if(!$strings{$string}) ....
You can create a batch file with .bat
extension with the following contents

git revert
simply creates a new commit that is the opposite of an existing commit.
It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:
$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
1 file changed, 1 insertion(+)
create mode 100644 README.md
$ echo "bad update" > README.md
$ git commit -am "bad update"
[master a1b9870] bad update
1 file changed, 1 insertion(+), 1 deletion(-)
In this example the commit history has two commits and the last one is a mistake. Using git revert:
$ git revert HEAD
[master 1db4eeb] Revert "bad update"
1 file changed, 1 insertion(+), 1 deletion(-)
There will be 3 commits in the log:
$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit
So there is a consistent history of what has happened, yet the files are as if the bad update never occured:
cat README.md
Initial text
It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).
do you have to do something else after?
A git revert
is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.
Do you have to commit the changes revert made or does revert directly commit to the repo?
git revert
is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.
Obviously you'll need to push again and probably announce to the team.
Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).
I've found that in 17.09 there is a simplest way to do it within docker container:
$ cat /proc/self/cgroup | head -n 1 | cut -d '/' -f3
4de1c09d3f1979147cd5672571b69abec03d606afcc7bdc54ddb2b69dec3861c
Or like it has already been told, a shorter version with
$ cat /etc/hostname
4de1c09d3f19
Or simply:
$ hostname
4de1c09d3f19
The localhost refers to the device on which the code is running, in this case the emulator.
If you want to refer to the computer which is running the Android simulator, use the IP address 10.0.2.2 instead.

You can add a class to the button and put some script redirecting it.
I do it this way:
<button class='buttonClass'>button name</button>
<script>
$(".buttonClass').click(function(){

});
</script>
You can simply use the NPM package var_dump
npm install var_dump --save-dev
Usage:
const var_dump = require('var_dump')
var variable = {
'data': {
'users': {
'id': 12,
'friends': [{
'id': 1,
'name': 'John Doe'
}]
}
}
}
// print the variable using var_dump
var_dump(variable)
This will print:
object(1) {
["data"] => object(1) {
["users"] => object(2) {
["id"] => number(12)
["friends"] => array(1) {
[0] => object(2) {
["id"] => number(1)
["name"] => string(8) "John Doe"
}
}
}
}
}

asks the manager to look up a color given a resource ID
As tangens said, the size of an array is fixed. But you have to instantiate it first, else it will be only a null reference.
String[] where = new String[10];
This array can contain only 10 elements. So you can append a value only 10 times. In your code you're accessing a null reference. That's why it doesnt work. In order to have a dynamically growing collection, use the ArrayList.

Two divs, one for header, one for data. Make the data div scrollable, and use JavaScript to set the width of the columns in the header to be the same as the widths in the data. I think the data columns widths need to be fixed rather than dynamic.
Include following line in your method there you want to trigger click event
angular.element('#btn_you_want_to_click_progmaticallt').triggerHandler('click');
});
Additionally a simpler example:
return (T)Activator.CreateInstance(typeof(T), new object[] { weight });
Note that using the new() constraint on T is only to make the compiler check for a public parameterless constructor at compile time, the actual code used to create the type is the Activator class.
You will need to ensure yourself regarding the specific constructor existing, and this kind of requirement may be a code smell (or rather something you should just try to avoid in the current version on c#).

Depending on what you want you might be interested in the SPL Object Storage class.
http://php.net/manual/en/class.splobjectstorage.php
It lets you use objects as keys, has an interface to count, get the hash and other goodies.
$s = new SplObjectStorage;
$o1 = new stdClass;
$o2 = new stdClass;
$o2->foo = 'bar';
$s[$o1] = 'baz';
$s[$o2] = 'bingo';
echo $s[$o1]; // 'baz'
echo $s[$o2]; // 'bingo'
Rows("2:2").Select
ActiveWindow.FreezePanes = True
Select a different range for a different effect, much the same way you would do manually. The "Freeze Top Row" really just is a shortcut new in Excel 2007 (and up), it contains no added functionality compared to earlier versions of Excel.
JonSkeet has a good answer but as an alternative if you wanted to keep the result more portable you could convert the date into an ISO 8601 format which could then be read into most other frameworks but this may fall outside your requirements.
value.ToUniversalTime().ToString("O");
The method array.toString()
actually calls array.join()
which result in a string concatenated by commas. ref
var array = ['a','b','c','d','e','f'];_x000D_
document.write(array.toString()); // "a,b,c,d,e,f"
_x000D_
Also, you can implicitly call Array.toString()
by making javascript coerce the Array
to an string
, like:
//will implicitly call array.toString()
str = ""+array;
str = `${array}`;
The join() method joins all elements of an array into a string.
It accepts a separator
as argument, but the default is already a comma ,
str = arr.join([separator = ','])
var array = ['A', 'B', 'C'];
var myVar1 = array.join(); // 'A,B,C'
var myVar2 = array.join(', '); // 'A, B, C'
var myVar3 = array.join(' + '); // 'A + B + C'
var myVar4 = array.join(''); // 'ABC'
If any element of the array is undefined or null , it is treated as an empty string.
It is available pretty much everywhere today, since IE 5.5 (1999~2000).
Another option is
if (myString?.trim()) {
...
}
This might be more desirable, that is use float instead
SELECT fullName, CAST(totalBal as float) totalBal FROM client_info ORDER BY totalBal DESC
public int height(Node node){
if(node==null)return 0;
else{
int l=height(node.leftChild);
int r=height(node.rightChild);

int r= height(n.rightChild);
System.out.println(l + " " +r);
if(Math.abs(l-r)>1)

I'm using intelliJ 15 community edition and I'm able to right click a file and select 'add to .gitignore'
Some of the tutorials I found that are easy to understand are:
It makes way more sense to break up your list into page-sized chunks, and only query your database one chunk at a time. This drastically reduces server processing time and page load time, as well as gives your user smaller pieces of info to digest, so he doesn't choke on whatever crap you're trying to feed him. The act of doing this is called pagination.
A basic pagination routine seems long and scary at first, but once you close your eyes, take a deep breath, and look at each piece of the script individually, you will find it's actually pretty easy stuff
The script:
// find out how many rows are in the table
$sql = "SELECT COUNT(*) FROM numbers";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];
// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);
// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
// cast var as int
$currentpage = (int) $_GET['currentpage'];
} else {
// default page num
$currentpage = 1;
} // end if
// if current page is greater than total pages...
if ($currentpage > $totalpages) {
// set current page to last page
$currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
// set current page to first page
$currentpage = 1;
} // end if
// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;
// get the info from the db
$sql = "SELECT id, number FROM numbers LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
// echo data
echo $list['id'] . " : " . $list['number'] . "<br />";
} // end while
/****** build the pagination links ******/
// range of num links to show
$range = 3;
// if not on page 1, don't show back links
if ($currentpage > 1) {
// show << link to go back to page 1
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
// get previous page num
$prevpage = $currentpage - 1;
// show < link to go back to 1 page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if
// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
} // end else
} // end if
} // end for
// if not on last page, show forward and last page links
if ($currentpage != $totalpages) {
// get next page
$nextpage = $currentpage + 1;
// echo forward link for next page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>></a> ";
// echo forward link for lastpage
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>>></a> ";
} // end if
/****** end build pagination links ******/
?>
This tutorial is intended for developers who wish to give their users the ability to step through a large number of database rows in manageable chunks instead of the whole lot in one go.
Here is what official hibernate docs tell us about this:
You can count the number of query results without returning them:
( (Integer) session.createQuery("select count(*) from ....").iterate().next() ).intValue()
However, it doesn't always return Integer
instance, so it is better to use java.lang.Number
for safety.
If the field name are different in entities
var result = from x in entity
join y in entity2 on
new {
field1= x.field1,
field2 = x.field2
}
equals
new {
field1= y.field1,
field2= y.myfield
}
select new {x,y});
This is a free library and works very easily : OpenHtmlToPdf
string timeStampForPdfName = DateTime.Now.ToString("yyMMddHHmmssff");
string serverPath = System.Web.Hosting.HostingEnvironment.MapPath("~/FolderName");
string pdfSavePath = Path.Combine(@serverPath, "FileName" + timeStampForPdfName + ".FileExtension");
//OpenHtmlToPdf Library used for Performing PDF Conversion
var pdf = Pdf.From(HTML_String).Content();
//FOr writing to file from a ByteArray
File.WriteAllBytes(pdfSavePath, pdf.ToArray()); // Requires System.Linq
If you have both jdk8 and jdk9 installed, you have to check wich version is
in the path and where JAVA_HOME is pointing to.
In the log you posted, I see that JAVA_HOME is leading to the JDK9.
modify your globel JAVA_HOME env var to target JDK8 or you can change JAVA_HOME in powershell before you use the cordova CLI if you want to use jdk8 only for cordova:
$env:JAVA_HOME="C:\Program Files\Java\jdk1.8.0_151"
**cordova build android**
The InnoDB engine does not store deleted data. As you insert and delete rows, unused space is left allocated within the InnoDB storage files. Over time, the overall space will not decrease, but over time the 'deleted and freed' space will be automatically reused by the DB server.
You can further tune and manage the space used by the engine through an manual re-org of the tables. To do this, dump the data in the affected tables using mysqldump, drop the tables, restart the mysql service, and then recreate the tables from the dump files.
The method you are trying to call is an instance-level method; you do not have an instance.
static
methods belong to the class, non-static
methods belong to instances of the class.
In singleton pattern you can create the singleton as an instance of a derived type, you can't do that with a static class.
Quick Example:
if( useD3D )
IRenderer::instance = new D3DRenderer
else
IRenderer::instance = new OpenGLRenderer
Just found a proper working solution for other guys,
// Returns true or false based on the radio button checked_x000D_
$('#test1').prop('checked')_x000D_
_x000D_
_x000D_
$('body').on('change','input[type="radio"]',function () {_x000D_
alert('Test1 checked = ' + $('#test1').prop('checked') + '. Test2 checked = ' + $('#test2').prop('checked') + '. Test3 checked = ' + $('#test3').prop('checked'));_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="radio" runat="server" name="testGroup" id="test1" /><label for="<%=test1.ClientID %>" style="cursor:hand" runat="server">Test1</label>_x000D_
_x000D_
<input type="radio" runat="server" name="testGroup" id="test2" /><label for="<%=test2.ClientID %>" style="cursor:hand" runat="server">Test2</label>_x000D_
_x000D_
<input type="radio" runat="server" name="testGroup" id="test3" /> <label for="<%=test3.ClientID %>" style="cursor:hand">Test3</label>
_x000D_
and in your method you can use like
return $('#test2').prop('checked');
I'd go for recursions:
l = ['a', 'b', 'c', 'd', 'e', ' ']
d = dict([(k, v) for k,v in zip (l[::2], l[1::2])])
Exactly like in JavaScript, you can use the parseInt
or parseFloat
functions, or simply use the unary +
operator:
var x = "32";
var y: number = +x;
All of the mentioned techniques will have correct typing and will correctly parse simple decimal integer strings like "123"
, but will behave differently for various other, possibly expected, cases (like "123.45"
) and corner cases (like null
).
Table taken from this answer
You should have that property defined in your model or entity class.
set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%
The single quotes do not indicate a string, they make it starts: 'C:\
instead of C:\
so
%name%
is the usual syntax for expanding a variable, the !name!
syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION
first, or by running the command prompt with CMD /V:ON
.
Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4
to keep the current PATH content, and add something to the end.
You can use the following methods to update the value of a reactive form control. Any of the following method will suit for your need.
Methods using setValue()
this.form.get("dept").setValue(selected.id);
this.form.controls["dept"].setValue(selected.id);
Methods using patchValue()
this.form.get("dept").patchValue(selected.id);
this.form.controls['dept'].patchValue(selected.id);
this.form.patchValue({"dept": selected.id});
Last method will loop thorough all the controls in the form so it is not preferred when updating single control
You can use any of the method inside the event handler
deptSelected(selected: { id: string; text: string }) {
// any of the above method can be added here
}
You can update multiple controls in the form group if required using the
this.form.patchValue({"dept": selected.id, "description":"description value"});
Try ^CTR.\*
, which literally means start of line, CTR, anything.
This will be case-sensitive, and setting non-case-sensitivity will depend on your programming language, or use ^[Cc][Tt][Rr].\*
if cross-environment case-insensitivity matters.
You can change
Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)
to
Range("B3:B65536").Copy
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues
BTW, if you have xls file (excel 2003), you would get an error if your lastrow
would be greater 3.
Try to use this code instead:
Sub Get_Data()
Dim lastrowDB As Long, lastrow As Long
Dim arr1, arr2, i As Integer
With Sheets("DB")
lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
End With
arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")
For i = LBound(arr1) To UBound(arr1)
With Sheets("Sheet1")
lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
End With
Next
Application.CutCopyMode = False
End Sub
Note, above code determines last non empty row on DB
sheet in column A
(variable lastrowDB
). If you need to find lastrow for each destination column in DB
sheet, use next modification:
For i = LBound(arr1) To UBound(arr1)
With Sheets("DB")
lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
End With
' NEXT CODE
Next
You could also use next approach instead Copy/PasteSpecial
. Replace
.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
with
Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value
Add this key in plist file...Everything will be alright..

Let's say you have three classes: Enemy1, Enemy2, Enemy3. This is how you instantiate them directly:
Enemy1()
Enemy2()
Enemy3()
but this will also work:
x = Enemy1
x()
x = Enemy2
x()
x = Enemy3
x()
Is this what you meant?
PEP 3101 proposes the replacement of the %
operator with the new, advanced string formatting in Python 3, where it would be the default.
Copy this export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk
to hadoop-env.sh
file.
JAVA_HOME
is the location where java binaries are present.
I had a very similar issue and I'm not quite sure what you're having a problem with, as your suggested code worked great for me. It immediately (a requirement of yours) triggers the following change code.
$('#selectField').change(function(){
if($('#selectField').val() == 'N'){
$('#secondaryInput').hide();
} else {
$('#secondaryInput').show();
}
});
Then I take the value from the database (this is used on a form for both new input and editing existing records), set it as the selected value, and add the piece I was missing to trigger the above code, ".change()".
$('#selectField').val(valueFromDatabase).change();
So that if the existing value from the database is 'N', it immediately hides the secondary input field in my form.
Assign each div a class
. Then you can perform actions on all of them:
$(".divClass").hide();
So each button can do:
$(".divClass").hide()
$("#specificDiv").show();
You can make this more generic, and use the obvious convention - the button and the div with the same number in the id are related. So:
$(".button").click(function() {
var divId = "#div" + $(this).attr("id").replace("showdiv", "");
$(".divClass").hide();
$(divId).show();
}
One has to remember that regexps aren't a silver bullet for everything string-y. Some stuff are simpler to do with a cursor and linear, manual, seeking. A CFL would do the trick pretty trivially, but there aren't many CFL implementations (afaik).
For those using git with Jenkins under a windows system, you need to configure the location of git.exe under: Manage Jenkins => Global Tool Configuration => Git => Path to Git executable and fill-in the path to git.exe, for example; C:\Program Files\Git\bin\git.exe
To clarify. What is important to know is that:
Here is a working snippet of code, where we do a little bit of date manipulation to ensure Mongo (here i am using mongoose module and want results for rows whose date attribute is less than (before) the date given as myDate param) can handle it correctly:
var inputDate = new Date(myDate.toISOString());
MyModel.find({
'date': { $lte: inputDate }
})
But if your Android App is only for personal purpose or created by you alone, you can use:
me.app_name.app
Whenever you want to use ant thread safe version of ant collection object,take help of java.util.concurrent.* package. It has almost all concurrent version of unsynchronized collection objects. eg: for ArrayList, you have java.util.concurrent.CopyOnWriteArrayList
You can do Collections.synchronizedCollection(any collection object),but remember this classical synchr. technique is expensive and comes with performence overhead. java.util.concurrent.* package is less expensive and manage the performance in better way by using mechanisms like
copy-on-write,compare-and-swap,Lock,snapshot iterators,etc.
So,Prefer something from java.util.concurrent.* package
You can also do this with linq if you'd like
var names = new List<string>() { "John", "Anna", "Monica" };
var joinedNames = names.Aggregate((a, b) => a + ", " + b);
Although I prefer the non-linq syntax in Quartermeister's answer and I think Aggregate
might perform slower (probably more string concatenation operations).
For C# 3.0, extension methods may only exist in top-level static classes.
the following will do:
date -d "$(date +%Y-%m-1) -1 month" +%-m
date -d "$(date +%Y-%m-1) 0 month" +%-m
date -d "$(date +%Y-%m-1) 1 month" +%-m
or as you need:
LAST_MONTH=`date -d "$(date +%Y-%m-1) -1 month" +%-m`
NEXT_MONTH=`date -d "$(date +%Y-%m-1) 1 month" +%-m`
THIS_MONTH=`date -d "$(date +%Y-%m-1) 0 month" +%-m`
you asked for output like 9,10,11, so I used the %-m
%m
(without -) will produce output like 09,... (leading zero)
this also works for more/less than 12 months:
date -d "$(date +%Y-%m-1) -13 month" +%-m
just try
date -d "$(date +%Y-%m-1) -13 month"
to see full result
Reply to abccd and Question to anyone:
The command: C:\Python34\Scripts>py -3 -m pip install pandas
executed just fine. Unfortunately, I can't import Pandas.
Directory path: C:\users\myname\downloads\miniconda3\lib\site-packages
My Question: How is it that Pandas' dependency packages(numpy, python-dateutil, pytz, six) also having the same above directory path are able to import just fine but Pandas does not?
import pandas
Traceback (most recent call last):
File "<pyshell#9>", line 1, in <module>

I finally got Pandas reinstalled and imported with the help of the following web pages: *http://pandas.pydata.org/pandas-docs/stable/pandas.pdf (Pages 403 and 404 of 2215 ... 2.2.2 Installing Pandas with Miniconda) *https://conda.io/docs/user-guide/install/download.html *https://conda.io/docs/user-guide/getting-started.html
After installing Miniconda, I created a new environment area to get Pandas reinstalled and imported. This new environment included the current Python version 3.6.3. I could not import Pandas using Python 3.4.4.
This sort of protection is normally provided by using HTTPS, so that all communication between the web server and the client is encrypted.

Try this regex, it works for me:
function isUrl(s) {
var regexp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/
return regexp.test(s);
}
Yes, ToList
will create a new list, but because in this case MyObject
is a reference type then the new list will contain references to the same objects as the original list.
Updating the SimpleInt
property of an object referenced in the new list will also affect the equivalent object in the original list.
(If MyObject
was declared as a struct
rather than a class
then the new list would contain copies of the elements in the original list, and updating a property of an element in the new list would not affect the equivalent element in the original list.)

Simple as that.
:focus
and :active
are two different states.
:focus
represents the state when the element is currently selected to receive input and :active
represents the state when the element is currently being activated by the user.For example let's say we have a <button>
. The <button>
will not have any state to begin with. It just exists. If we use Tab to give "focus" to the <button>
, it now enters its :focus
state. If you then click (or press space), you then make the button enter its (:active
) state.
On that note, when you click on an element, you give it focus, which also cultivates the illusion that :focus
and :active
are the same. They are not the same. When clicked the button is in :focus:active
state.
An example:
<style type="text/css">_x000D_
button { font-weight: normal; color: black; }_x000D_
button:focus { color: red; }_x000D_
button:active { font-weight: bold; }_x000D_
</style>_x000D_
_x000D_
<button>_x000D_
When clicked, my text turns red AND bold!<br />_x000D_
But not when focused only,<br />_x000D_
where my text just turns red_x000D_
</button>
_x000D_

I know this question already has an answer, but I found out an even simpler way of doing this.
Just add
<tr height = 20px></tr>
Into the table where you want to have an empty row. It works fine in my program and it's probably the quickest solution possible.
ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;
This is all you need to:
id
columnCredit is given to @resnyanskiy who gave this answer in a comment.
int StringToWString(std::wstring &ws, const std::string &s)
{
std::wstring wsTmp(s.begin(), s.end());
ws = wsTmp;
return 0;
}
Following code gives intended results.
string text="some interesting text\nsome text that should be in the same line\r\nsome
text should be in another line"
var results = text.Split(new[] {"\n","\r\n"}, StringSplitOptions.None);
To remove all child elements from your div:
$('#mysweetdiv').empty();
.removeData()
and the corresponding .data()
function are used to attach data behind an element, say if you wanted to note that a specific list element referred to user ID 25 in your database:
var $li = $('<li>Joe</li>').data('id', 25);
If you use the JSON Serializer, you can simply store your object in string format as such
myHiddenText.value = JSON.stringify( myObject );
You can then get the value back with
myObject = JSON.parse( myHiddenText.value );
However, if you're not going to pass this value across page submits, it might be easier for you, and you'll save yourself a lot of serialization, if you just tuck it away as a global javascript variable.

grep -rHInE '/bin/sh' /
returns over 2700 results) expect a fully POSIX shell at/bin/sh
. The bash shell isn't just POSIX plus extra builtins. There are builtins (and more) that behave entirely different than those in POSIX. I FULLY support avoiding POSIX (and the fallacy that any script that you didn't test on another shell is going to work because you think you avoided basmisms) and just using bashism. But you do that with a proper shebang in your script. Not by pulling the POSIX shell out from under the entire OS. (Unless you have time to verify all 2700 plus scripts that come with Linux plus all those in any packages you install.)

You might not be aware that an import is global already. If you export an object (singleton) it is then globally accessible as an import statement and it can also be modified globally.
If you want to initialize something globally but ensure its only modified once, you can use this singleton approach that initially has modifiable properties but then you can use Object.freeze
after its first use to ensure its immutable in your init scenario.
const myInitObject = {}
export default myInitObject
then in your init method referencing it:
import myInitObject from './myInitObject'
myInitObject.someProp = 'i am about to get cold'
Object.freeze(myInitObject)
The myInitObject
will still be global as it can be referenced anywhere as an import but will remain frozen and throw if anyone attempts to modify it.
https://codesandbox.io/s/react-typescript-playground-forked-h8rpu
(what I was looking for actually) In this scenario you can also initialize global objects cleanly when referencing environment variables.
Creating a .env file at the root of your project with prefixed REACT_APP_
variables inside does quite nicely. You can reference within your JS and JSX process.env.REACT_APP_SOME_VAR
as you need AND it's immutable by design.
This avoids having to set window.myVar = %REACT_APP_MY_VAR%
in HTML.

If you have a single Buffer
you can use its toString
method that will convert all or part of the binary contents to a string using a specific encoding. It defaults to utf8
if you don't provide a parameter, but I've explicitly set the encoding in this example.
var req = http.request(reqOptions, function(res) {
...
res.on('data', function(chunk) {
var textChunk = chunk.toString('utf8');
// process utf8 text chunk
});
});
If you have streamed buffers like in the question above where the first byte of a multi-byte UTF8
-character may be contained in the first Buffer
(chunk) and the second byte in the second Buffer
then you should use a StringDecoder
. :
var StringDecoder = require('string_decoder').StringDecoder;
var req = http.request(reqOptions, function(res) {
...
var decoder = new StringDecoder('utf8');
res.on('data', function(chunk) {
var textChunk = decoder.write(chunk);
// process utf8 text chunk
});
});
This way bytes of incomplete characters are buffered by the StringDecoder
until all required bytes were written to the decoder.
Result Set
are actually contains multiple rows of data, and use a cursor to point out current position. So in your case, rs4.getString(1)
only get you the data in first column of first row. In order to change to next row, you need to call next()
a quick example
while (rs.next()) {
String sid = rs.getString(1);
String lid = rs.getString(2);
// Do whatever you want to do with these 2 values
}
there are many useful method in ResultSet
, you should take a look :)
The Microsoft certification material addresses this same question. In the .NET world, the overhead for the StringBuilder object makes a simple concatenation of 2 String objects more efficient. I would assume a similar answer for Java strings.
Swift 5
//MARK:- if you are in UITabBarController
self.selectedIndex = 1
or
tabBarController?.selectedIndex = 1
Basically, what is happening is that your user is either closing the browser tab, or is navigating away to a different page, before communication was complete. Your webserver (Jetty) generates this exception because it is unable to send the remaining bytes.
org.eclipse.jetty.io.EofException: null

This is not an error on your application logic side. This is simply due to user behavior. There is nothing wrong in your code per se.
There are two things you may be able to do:
I created a bot to get User or GroupChat id,
just send the /my_id
to telegram bot @get_id_bot
.
It does not only work for user chat ID, but also for group chat ID.
To get group chat ID, first you have to add the bot to the group,
then send /my_id
in the group.
Here's the link to the bot.
Rename the Column by doing the following:
dataTable.Columns["ColumnName"].ColumnName = "newColumnName";
The typeof
operator isn't an infix (so the LHS of your example doesn't make sense).
You need to use it like so...
if (typeof a_string == 'string') {
// This is a string.
}
Remember, typeof
is an operator, not a function. Despite this, you will see typeof(var)
being used a lot in the wild. This makes as much sense as var a = 4 + (1)
.
Also, you may as well use ==
(equality comparison operator) since both operands are String
s (typeof
always returns a String
), JavaScript is defined to perform the same steps had I used ===
(strict comparison operator).
As Box9 mentions, this won't detect a instantiated String
object.
You can detect for that with....
var isString = str instanceof String;
...or...
var isString = str.constructor == String;
But this won't work in a multi window
environment (think iframe
s).
You can get around this with...
var isString = Object.prototype.toString.call(str) == '[object String]';
But again, (as Box9 mentions), you are better off just using the literal String
format, e.g. var str = 'I am a string';
.
I was working on the bounding box problem as a side issue to finding all the points within SrcRad radius of a static LAT, LONG point. There have been quite a few calculations that use
maxLon = $lon + rad2deg($rad/$R/cos(deg2rad($lat)));
minLon = $lon - rad2deg($rad/$R/cos(deg2rad($lat)));
to calculate the longitude bounds, but I found this to not give all the answers that were needed. Because what you really want to do is
(SrcRad/RadEarth)/cos(deg2rad(lat))
I know, I know the answer should be the same, but I found that it wasn't. It appeared that by not making sure I was doing the (SRCrad/RadEarth) First and then dividing by the Cos part I was leaving out some location points.
After you get all your bounding box points, if you have a function that calculates the Point to Point Distance given lat, long it is easy to only get those points that are a certain distance radius from the fixed point. Here is what I did. I know it took a few extra steps but it helped me
-- GLOBAL Constants
gc_pi CONSTANT REAL := 3.14159265359; -- Pi
-- Conversion Factor Constants
gc_rad_to_degs CONSTANT NUMBER := 180/gc_pi; -- Conversion for Radians to Degrees 180/pi
gc_deg_to_rads CONSTANT NUMBER := gc_pi/180; --Conversion of Degrees to Radians
lv_stat_lat -- The static latitude point that I am searching from
lv_stat_long -- The static longitude point that I am searching from
-- Angular radius ratio in radians
lv_ang_radius := lv_search_radius / lv_earth_radius;
lv_bb_maxlat := lv_stat_lat + (gc_rad_to_deg * lv_ang_radius);
lv_bb_minlat := lv_stat_lat - (gc_rad_to_deg * lv_ang_radius);
--Here's the tricky part, accounting for the Longitude getting smaller as we move up the latitiude scale
-- I seperated the parts of the equation to make it easier to debug and understand
-- I may not be a smart man but I know what the right answer is... :-)
lv_int_calc := gc_deg_to_rads * lv_stat_lat;
lv_int_calc := COS(lv_int_calc);
lv_int_calc := lv_ang_radius/lv_int_calc;
lv_int_calc := gc_rad_to_degs*lv_int_calc;
lv_bb_maxlong := lv_stat_long + lv_int_calc;
lv_bb_minlong := lv_stat_long - lv_int_calc;
-- Now select the values from your location datatable
SELECT * FROM (
SELECT cityaliasname, city, state, zipcode, latitude, longitude,
-- The actual distance in miles
spherecos_pnttopntdist(lv_stat_lat, lv_stat_long, latitude, longitude, 'M') as miles_dist
FROM Location_Table
WHERE latitude between lv_bb_minlat AND lv_bb_maxlat
AND longitude between lv_bb_minlong and lv_bb_maxlong)
WHERE miles_dist <= lv_limit_distance_miles
order by miles_dist
;
I have exactly the same issue with you. I have TortoiseSVN installed on my windows, I have also eclipse installed, in the eclipse, I have the subclipse 1.4 installed.
here is the issue I have proxy settings, I can open the repo through web browser, for some reason, I cannot open a repo through svn. I tried to change the proxy following the link below Eclipse Kepler not connecting to internet via proxy. It doesn't work.
Finally I found out a solution
You have to change the proxy setting in TortoiseSVN. After I enable the proxy setting the same with my browser. The issue is gone.
here is the link of how to enable proxy setting in TortoiseSVN https://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-settings.html Seach "Network Settings" on the page above
There is no need to use :checkbox
, also replace #activelist
with #inactivelist
:
$('#inactivelist').change(function () {
alert('changed');
});
First you create method in your fragment
like
public void name()
{
}
in your activity
you add this
add onCreate()
method
myfragment fragment=new myfragment()
finally call the method where you want to call add this
fragment.method_name();
try this code
Here is the another solution. Please check this.
$first = '10/30/2017'; //starting date
$last= '10/11/2017'; //ending date
$first_time_arr=explode('/',$first);
$last_time_arr=explode('/',$last);
//create timestamp of starting date
$start_timestamp=mktime(0,0,0, $first_time_arr[0], $first_time_arr[1],$first_time_arr[2]);
//create timestamp of ending date
$end_timestamp=mktime(0,0,0, $last_time_arr[0], $last_time_arr[1],$last_time_arr[2]);
$date_arr=array();
for($i=$start_timestamp;$i<=$end_timestamp;$i=$i+86400){
$date_arr[]=date("Y-m-d",$i); //this will save all dates in array
}

Has anyone else noticed that the json string/object is invalid in all answers except for David Hedlund's? :)
JSON objects must be formatted in the following manner: {"key": ("value" | 0 | false)}. Also, writing it out as a string requires much less than stringifying the object...

For .Net 4+:
string s = "{ \"user\" : { \"id\" : 12345, \"screen_name\" : \"twitpicuser\"}}";
var serializer = new JavaScriptSerializer();
dynamic usr = serializer.DeserializeObject(s);
var UserId = usr["user"]["id"];
For .Net 2/3.5: This code should work on JSON with 1 level
samplejson.aspx

var serializer = new JavaScriptSerializer();
Dictionary<string, object> result = (serializer.DeserializeObject(s) as Dictionary<string, object>);
var UserId = result["id"];

To lock whole workbook from opening, Thisworkbook.password
option can be used in VBA.
If you want to Protect Worksheets, then you have to first Lock the cells with option Thisworkbook.sheets.cells.locked = True
and then use the option Thisworkbook.sheets.protect password:="pwd"
.
Primarily search for these keywords: Thisworkbook.password
or Thisworkbook.Sheets.Cells.Locked

Just ran into this issue and lost the whole day solving it. Try to increase memory_limit
, that worked for me!
There's no proper way to cast this to int
in general case. C99 standard library provides intptr_t
and uintptr_t
typedefs, which are supposed to be used whenever the need to perform such a cast comes about. If your standard library (even if it is not C99) happens to provide these types - use them. If not, check the pointer size on your platform, define these typedefs accordingly yourself and use them.
This is handled by adding some padding
to the top of the <body>
.
As per Bootstrap's documentation on .navbar-fixed-top
, try out your own values or use our snippet below. Tip: By default, the navbar
is 50px
high.
body {
padding-top: 70px;
}
Also, take a look at the source for this example and open starter-template.css
.
Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.
To get the string representation using at least 4 digits:
int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"
1: I have downloaded the mysql-connector-java-5.1.24-bin.jar
Okay.
2: I have created a lib folder in my project and put the jar in there.
Wrong. You need to drop JAR in /WEB-INF/lib
folder. You don't need to create any additional folders.
3: properties of project->build path->add JAR and selected the JAR above.
Unnecessary. Undo it all to avoid possible conflicts.
4: I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql
This exception can have 2 causes:
JDBC URL is not recognized by any of the loaded JDBC drivers. Indeed, the JDBC URL is wrong, there should as per the MySQL JDBC driver documentation be another colon between the scheme and the host.
jdbc:mysql://localhost:3306/mysql
Hmm, Arraylist can be used in cases like follows I guess:
For eg, you need to import and access all elements in a contact list (the size of which is unknown to you)
your exists syntax is wrong and you should seperate DDL with go like below
if exists(select 1 from sys.views where name='tst' and type='v')
drop view tst;
go
create view tst
as
select * from test
you also can check existence test, with object_id like below
if object_id('tst','v') is not null
drop view tst;
go
create view tst
as
select * from test
In SQL 2016,you can use below syntax to drop
Drop view if exists dbo.tst
From SQL2016 CU1,you can do below
create or alter view vwTest
as
select 1 as col;
go
You can pass an instance of java.lang.Class that represents the type, i.e.
private void foo(Class cls)
You can also use:
Range( RangeName ).end(xlDown).row
to find the last row with data in it starting at your named range.

These are all good answers. BUT if you're feeling lazy, and the file isn't that big, and security is not an issue (you know you don't have a tainted filename), then you can shell out:
$x=`cat /tmp/foo`; # note backticks, qw"cat ..." also works
public boolean isAlertPresent()
{
try
{
driver.switchTo().alert();
return true;
} // try
catch (NoAlertPresentException Ex)
{
return false;
} // catch
} // isAlertPresent()
