mysqldump --extended-insert=FALSE
Be aware that multiple inserts will be slower than one big insert.
I've had a similar issue, that took a bit to troubleshoot, so I thought to share it:
The namespace that could not be resolved in my case was Company.Project.Common.Models.EF. I had added a file in a new Company.Project.BusinessLogic.Common namespace.
The majority of the files were having a
using Company.Project;
And then referencing the models as Common.Models.EF. All the files that also had a
using Company.Project.BusinessLogic;
Were failing as VS could not determine which namespace to use.
The solution has been to change the second namespace to Company.Project.BusinessLogic.CommonServices
in angular4 foreach like that. try this.
selectChildren(data, $event) {
let parentChecked = data.checked;
this.hierarchicalData.forEach(obj => {
obj.forEach(childObj=> {
value.checked = parentChecked;
});
});
}
For a more convenient installer, you may want to use
apt-cyg
as your package manager. Its syntax similar to
apt-get
, which is a plus. For this, follow the above
steps and then use Cygwin Bash for the following steps
wget https://raw.githubusercontent.com/transcode-open/apt-cyg/master/apt-cyg
chmod +x apt-cyg
mv apt-cyg /usr/local/bin
Now that apt-cyg
is installed. Here are few examples of
installing some packages
apt-cyg install nano
apt-cyg install git
apt-cyg install ca-certificates
This is example code I have written for you to understand this concept:
var foo = 5;
bar = 2;
fooba = 3;
// Execute an anonymous function
(function() {
bar = 100; //overwrites global scope bar
var foo = 4; //a new foo variable is created in this' function's scope
var fooba = 900; //same as above
document.write(foo); //prints 4
document.write(bar); //prints 100
document.write(fooba); //prints 900
})();
document.write('<br/>');
document.write('<br/>');
document.write(foo); //prints 5
document.write(bar); //prints 100
document.write(fooba); //prints 3
You don't need a function for it - simply use the bracket notation:
var side = columns['right'];
This is equal to dot notation, var side = columns.right;
, except the fact that right
could also come from a variable, function return value, etc., when using bracket notation.
If you NEED a function for it, here it is:
function read_prop(obj, prop) {
return obj[prop];
}
To answer some of the comments below that aren't directly related to the original question, nested objects can be referenced through multiple brackets. If you have a nested object like so:
var foo = { a: 1, b: 2, c: {x: 999, y:998, z: 997}};
you can access property x
of c
as follows:
var cx = foo['c']['x']
If a property is undefined, an attempt to reference it will return undefined
(not null
or false
):
foo['c']['q'] === null
// returns false
foo['c']['q'] === false
// returns false
foo['c']['q'] === undefined
// returns true
You can set the title in action-bar using AndroidManifest.xml
. Add label to the activity
<activity
android:name=".YourActivity"
android:label="Your Title" />

If you’re deploying a large migration or need to disable access to your application for some length of time, you can use Heroku’s built in maintenance mode. It will serve a static page to all visitors, while still allowing you to run rake tasks or console commands.
$ heroku maintenance:on
Maintenance mode enabled.
and later
$ heroku maintenance:off
Maintenance mode disabled.
In the WPF application, you can handle this by handling TextChanged
event:
void arsDigitTextBox_TextChanged(object sender, System.Windows.Controls.TextChangedEventArgs e)
{
Regex regex = new Regex("[^0-9]+");
bool handle = regex.IsMatch(this.Text);
if (handle)
{
StringBuilder dd = new StringBuilder();
int i = -1;
int cursor = -1;
foreach (char item in this.Text)
{
i++;
if (char.IsDigit(item))
dd.Append(item);
else if(cursor == -1)
cursor = i;
}
this.Text = dd.ToString();
if (i == -1)
this.SelectionStart = this.Text.Length;
else

First of all, forget about GNUStep tools. Neither ProjectManager nor ProjectCenter can be called an IDE. With all due respect, it looks like guys from GNUStep project are stuck in the late 80-s (which is when NeXTSTEP first appeared).
ctags
support Objective-C since r771 (be sure to pick the pre-release 5.9 version and add --langmap=ObjectiveC:.m.h
to the command line, see here), so you'll have decent code completion/tag navigation.
Here's a short howto on adding Objective-C support to Vim tagbar plugin.
The same applies to etags
shipped with modern Emacsen, so you can start with Emacs Objective C Mode. YASnippet will provide useful templates:
and if you want something more intelligent than the basic tags-based code completion, take a look at this question.
CDT supports Makefile
-based projects:
-- so technically you can build your Objective-C projects out of the box (on Windows, you'll need the Cygwin or MinGW toolchain). The only problem is the code editor which will report plenty of errors against what it thinks is a pure C code (on-the-fly code checking can be turned off, but still...). If you want proper syntax highlighting, you can add Eclim to your Eclipse and enjoy all the good features of both Eclipse and Vim (see above).
Another promising Eclipse plugin is Colorer, but it doesn't support Objective-C as of yet. Feel free to file a feature request though.
SlickEdit, among other features of a great IDE, does support Objective-C. While it is fairly complex to learn (not as complex as Emacs though), I believe this is your best option provided you don't mind purchasing it (the price is quite affordable).
Additionally, it has an Eclipse plugin which can be used as an alternative to the stand-alone editor.
Rumor has it there exists a KDevelop patch (15 year old, but who cares?). I personally don't think KDevelop is feature-superior compared to Emacsen, so I wouldn't bother trying it.
The above also applies to Objective-C development on Linux, since all of the tools mentioned are more or less portable.
#include <iostream>
#include <iomanip>
using namespace std;
You can enter the line using namespace std;
for your convenience. Otherwise, you'll have to explicitly add std::
every time you wish to use cout
, fixed
, showpoint
, setprecision(2)
and endl
int main()
{
double num1 = 3.12345678;
cout << fixed << showpoint;
cout << setprecision(2);
cout << num1 << endl;
return 0;
}
You can use a lookaround:
^(?=.*[A-Za-z0-9])[A-Za-z0-9 _]*$
It will check ahead that the string has a letter or number, if it does it will check that the rest of the chars meet your requirements. This can probably be improved upon, but it seems to work with my tests.
UPDATE:
Adding modifications suggested by Chris Lutz:
^(?=.*[^\W_])[\w ]*$/
you can use this.finish() if you want to close current activity.
this.finish()
Ok, as this thread appears among the first results of google and for other users having the same question, you don't have to reivent the wheel as pointed by trueboroda there is the ng2-file-upload library which simplify this process of uploading a file with angular 6 and 7 all you need to do is:
Install the latest Angular CLI
yarn add global @angular/cli
Then install rx-compat for compatibility concern
npm install rxjs-compat --save
Install ng2-file-upload
npm install ng2-file-upload --save
Import FileSelectDirective Directive in your module.
import { FileSelectDirective } from 'ng2-file-upload';
Add it to [declarations] under @NgModule:
declarations: [ ... FileSelectDirective , ... ]
In your component
import { FileUploader } from 'ng2-file-upload/ng2-file-upload';
...
export class AppComponent implements OnInit {
public uploader: FileUploader = new FileUploader({url: URL, itemAlias: 'photo'});
}
Template
<input type="file" name="photo" ng2FileSelect [uploader]="uploader" />

Updated version for SQL Server 2017 using STRING_AGG function to construct the pivot column list:
create table temp
(
date datetime,
category varchar(3),
amount money
);
insert into temp values ('20120101', 'ABC', 1000.00);
insert into temp values ('20120201', 'DEF', 500.00);
insert into temp values ('20120201', 'GHI', 800.00);
insert into temp values ('20120210', 'DEF', 700.00);
insert into temp values ('20120301', 'ABC', 1100.00);
DECLARE @cols AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX);
SET @cols = (SELECT STRING_AGG(category,',') FROM (SELECT DISTINCT category FROM temp WHERE category IS NOT NULL)t);
set @query = 'SELECT date, ' + @cols + ' from
(
select date
, amount
, category
from temp
) x
pivot
(
max(amount)
for category in (' + @cols + ')
) p ';
execute(@query);
drop table temp;
An alternate to the above solutions is using Aliases for Tables:
UPDATE T1 SET T1.extrasPrice = (SELECT SUM(T2.Price) FROM BookingPitchExtras T2 WHERE T2.pitchID = T1.ID)
FROM BookingPitches T1;
This Might be one way.
SELECT TOP 1 [Column Name] FROM (SELECT [Column Name] FROM [table]
WHERE [conditions]
UNION ALL
SELECT 0 )A ORDER BY [Column Name] DESC
You are attempting to call
List<EmailData>.Add(string,string,string). Try this:

def removeduplicates(a):
seen = set()
for i in a:
if i not in seen:
seen.add(i)
return seen
print(removeduplicates([1,1,2,2]))
FireFox is reporting that the response did not even specify the character encoding in the header, eg. Content-Type: text/html; charset=utf-8
and not just Content-Type: text/plain;
.
What web server are you using? Are you sure you are not requesting a non-existing page (404) that responds poorly?
As suggested you need to use ng-options and unfortunately I believe you need to reference the array element for a default (unless the array is an array of strings).
The JavaScript:
function AppCtrl($scope) {
$scope.operators = [
{value: 'eq', displayName: 'equals'},
{value: 'neq', displayName: 'not equal'}
]
$scope.filterCondition={
operator: $scope.operators[0]
}
}
The HTML:
<body ng-app ng-controller="AppCtrl">
<div>Operator is: {{filterCondition.operator.value}}</div>
<select ng-model="filterCondition.operator" ng-options="operator.displayName for operator in operators">
</select>
</body>
But for a better check:
if(str === null || str === '')
{
//enter code here
}

You can also find range of prime numbers till the given number by user.
CODE:
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Input a number to find Prime numbers\n");
int inp = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("\n Prime Numbers are:\n------------------------------");
int count = 0;
for (int i = 1; i <= inp; i++)
{
for (int j = 2; j < i; j++) // j=2 because if we divide any number with 1 the remaider will always 0, so skip this step to minimize time duration.
{
if (i % j != 0)
{
count += 1;
}
}
if (count == (i - 2))
{
Console.Write(i + "\t");
}
count = 0;
}
Console.ReadKey();
}
}
an Enum is a safe-type so you can't assign a new value at the runtime. Moreover you can use it in a switch statement (like an int).
Here are another 2 options that allow you to invoke SaveChanges() in a for each loop.
The first option is use one DBContext to generate your list objects to iterate through, and then create a 2nd DBContext to call SaveChanges() on. Here is an example:
//Get your IQueryable list of objects from your main DBContext(db)
IQueryable<Object> objects = db.Object.Where(whatever where clause you desire);
//Create a new DBContext outside of the foreach loop
using (DBContext dbMod = new DBContext())
{
//Loop through the IQueryable
foreach (Object object in objects)
{
//Get the same object you are operating on in the foreach loop from the new DBContext(dbMod) using the objects id
Object objectMod = dbMod.Object.Find(object.id);
//Make whatever changes you need on objectMod
objectMod.RightNow = DateTime.Now;
//Invoke SaveChanges() on the dbMod context
dbMod.SaveChanges()
}
}
The 2nd option is to get a list of database objects from the DBContext, but to select only the id's. And then iterate through the list of id's (presumably an int) and get the object corresponding to each int, and invoke SaveChanges() that way. The idea behind this method is grabbing a large list of integers, is a lot more efficient then getting a large list of db objects and calling .ToList() on the entire object. Here is an example of this method:
//Get the list of objects you want from your DBContext, and select just the Id's and create a list
List<int> Ids = db.Object.Where(enter where clause here)Select(m => m.Id).ToList();
var objects = Ids.Select(id => db.Objects.Find(id));
foreach (var object in objects)
{
object.RightNow = DateTime.Now;
db.SaveChanges()
}
Many of the previous answers used backtracking. This is the asymptotically optimal way O(n*n!) of generating permutations after initial sorting

while (j >= 0 && seq[j] >= seq[j + 1]) {
--j;
}
if (j == -1)
return false;// no more perm
// 3: Find last l such that seq[j] <= seq[l], then exchange elements j and l
int l = len - 1;
while (seq[j] >= seq[l]) {
--l;
}
swap(seq, j, l);
// 4: Reverse elements j+1 ... count-1:
reverseSubArray(seq, j + 1, len - 1);
// return seq, add store next perm
return true;
}
private static void swap(char[] a, int i, int j) {
char temp = a[i];
a[i] = a[j];
a[j] = temp;
}

}
}

Depending on the type of your variable, one of abs(int)
, labs(long)
, llabs(long long)
, imaxabs(intmax_t)
, fabsf(float)
, fabs(double)
, or fabsl(long double)
.
Those functions are all part of the C standard library, and so are present both in Objective-C and plain C (and are generally available in C++ programs too.)
(Alas, there is no habs(short)
function. Or scabs(signed char)
for that matter...)
Apple's and GNU's Objective-C headers also include an ABS()
macro which is type-agnostic. I don't recommend using ABS()
however as it is not guaranteed to be side-effect-safe. For instance, ABS(a++)
will have an undefined result.
If you're using C++ or Objective-C++, you can bring in the <cmath>
header and use std::abs()
, which is templated for all the standard integer and floating-point types.
You can open with
startActivityForResult(new Intent(android.provider.Settings.ACTION_SETTINGS), 0);
You can return by pressing back button on device.
When I had this issue the cause was a relative reference to template files when using the ui.bootstrap.modal module.
templateUrl: 'js/templates/modal.html'
This works from a root domain (www.example.com) but when a path is added (www.example.com/path/) the reference breaks. The answer in my case was simply to making the reference absolute (js/ -> /js/).
templateUrl: '/js/templates/modal.html'
Ok, finally found the solution.
Probably due to lack of experience with ReactJS and web development...
var Task = React.createClass({
render: function() {
var percentage = this.props.children + '%';
....
<div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
...
I created the percentage variable outside in the render function.
If sometimes a link! will not work. so create a temporary object and take all values from the writable object then change the value and assign it to the writable object. it should perfectly.
var globalObject = {

}
function() {
let localObject = {
name:'a',
age:21
}
this.globalObject = localObject;

If anyone still reading this thread and not able to get this working, I'm very sorry to tell you this way to intercept motion event is considered as bug and fix in android >=4.2.
The motion event you intercepted, although has action as ACTION_OUTSIDE, return 0 in getX and getY. This means you can not see all the motion position on screen, nor can you do anything. I know the doc said It will get x and y, but the truth is it WILL NOT. It seems that this is to block key logger.
If anyone do have a workaround, please leave your comment.
ref: Why does ACTION_OUTSIDE return 0 everytime on KitKat 4.4.2?
I've been using the following:
INSERT INTO [TableName] (ID, Name)
values (NEWID(), NEWID())
GO 10
It will add ten rows with unique GUIDs for ID and Name.
Note: do not end the last line (GO 10) with ';' because it will throw error: A fatal scripting error occurred. Incorrect syntax was encountered while parsing GO.
As mentioned here - https://kite.com/python/answers/how-to-append-a-list-as-a-row-to-a-pandas-dataframe-in-python, you'll need to first convert the list to a series then append the series to dataframe.
df = pd.DataFrame([[1, 2], [3, 4]], columns = ["a", "b"])
to_append = [5, 6]
a_series = pd.Series(to_append, index = df.columns)
df = df.append(a_series, ignore_index=True)
Search for the Gemfile file in your project, go to that directory and then run "bundle install". prior to running this command make sure you have installed the gem "sudo gem install bundler"
I was getting a consistent 15 second delay on the first request after 4 minutes of inactivity. My problem was that my app was using Windows Integrated Authentication to SQL Server and the service profile was in a different domain than the server. This caused a cross-domain authentication from IIS to SQL upon app initialization - and this was the real source of my delay. I changed to using a SQL login instead of windows authentication. The delay was immediately gone. I still have all the app initialization settings in place to help improve performance but they may have not been needed at all in my case.
Note that sometimes you will want to use the class type name inside its own definition, for example when using Python Typing module, e.g.
class Tree:
def __init__(self, left: Tree, right: Tree):
self.left = left
self.right = right
This will also result in
NameError: name 'Tree' is not defined
That's because the class has not been defined yet at this point. The workaround is using so called Forward Reference, i.e. wrapping a class name in a string, i.e.
class Tree:
def __init__(self, left: 'Tree', right: 'Tree'):
self.left = left
self.right = right
This is a bit late but may help someone. Not sure if diff or rsync spit out just filenames in a bare format like this. Thanks to plhn for giving that nice solution which I expanded upon below.
If you want just the filenames so it's easy to just copy the files you need in a clean format, you can use the find command.
comm -23 <(find dir1 | sed 's/dir1/\//'| sort) <(find dir2 | sed 's/dir2/\//'| sort) | sed 's/^\//dir1/'
This assumes that both dir1 and dir2 are in the same parent folder. sed just removes the parent folder so you can compare apples with apples. The last sed just puts the dir1 name back.
If you just want files:
comm -23 <(find dir1 -type f | sed 's/dir1/\//'| sort) <(find dir2 -type f | sed 's/dir2/\//'| sort) | sed 's/^\//dir1/'
Similarly for directories:
comm -23 <(find dir1 -type d | sed 's/dir1/\//'| sort) <(find dir2 -type d | sed 's/dir2/\//'| sort) | sed 's/^\//dir1/'

Add one more condition in where clause
SELECT * FROM product
WHERE pdate >= DATEADD(day,-30,GETDATE())
and pdate <= getdate()
Or use DateDiff
SELECT * FROM product
WHERE DATEDIFF(day,pdate,GETDATE()) between 0 and 30
I opened up my Software & Updates program
and switched from my country to the main servers like so:
After I done this and run the sudo apt update
commando again, my problems where gone.
I have occurred the same error look following example-
async.waterfall([function(waterCB) {
waterCB(null);
}, function(**inputArray**, waterCB) {
waterCB(null);
}], function(waterErr, waterResult) {
console.log('Done');
});
In the above waterfall function, I am accepting inputArray parameter in waterfall 2nd function. But this inputArray not passed in waterfall 1st function in waterCB.
Cheak your function parameters Below are a correct example.
async.waterfall([function(waterCB) {
waterCB(null, **inputArray**);
}, function(**inputArray**, waterCB) {
waterCB(null);
}], function(waterErr, waterResult) {
console.log('Done');
});
Thanks
One of these will work...
<head>_x000D_
<meta http-equiv='refresh' content='0; URL=http://example.com/'>_x000D_
</head>
_x000D_
...or it can done with JavaScript:
window.location.href = 'https://example.com/';
_x000D_
The way I handled this was switching the className of a label based on a condition. This way you only need one label and you can have different classes for different states... Hope that helps!
In my case, I needed an additional command,
git branch --unset-upstream
to get my renamed branch to push up to origin newname
.
(For ease of typing), I first git checkout oldname
.
Then run the following:
git branch -m newname <br/>
git push origin :oldname*or*
git push origin --delete oldname
git branch --unset-upstream
git push -u origin newname
or git push origin newname
This extra step may only be necessary because I (tend to) set up remote tracking on my branches via git push
-u
origin oldname
. This way, when I have oldname
checked out, I subsequently only need to type git push
rather than git push origin oldname
.
If I do not use the command git branch --unset-upstream
before git push origin newbranch
, git re-creates oldbranch
and pushes newbranch
to origin oldbranch
-- defeating my intent.
There is an .Offset property on a Range class which allows you to do just what you need
ActiveCell.Offset(numRows, numCols)
follow up on a comment:
Dim newRange as Range
Set newRange = Range(ActiveCell, ActiveCell.Offset(numRows, numCols))
and you can verify by MsgBox newRange.Address
One way to do this is by changing the parent of the overlapping picture box to the PictureBox over which it is lapping. Since the Visual Studio designer doesn't allow you to add a PictureBox to a PictureBox, this will have to be done in your code (Form1.cs) and within the Intializing function:
public Form1()
{
InitializeComponent();
pictureBox7.Controls.Add(pictureBox8);
pictureBox8.Location = new Point(0, 0);
pictureBox8.BackColor = Color.Transparent;
}
Just change the picture box names to what ever you need. This should return:
If you also want the values you can use the inspect
module
import inspect
def func(a, b, c):
frame = inspect.currentframe()
args, _, _, values = inspect.getargvalues(frame)
print 'function name "%s"' % inspect.getframeinfo(frame)[2]
for i in args:
print " %s = %s" % (i, values[i])
return [(i, values[i]) for i in args]
>>> func(1, 2, 3)
function name "func"
a = 1
b = 2
c = 3
[('a', 1), ('b', 2), ('c', 3)]
These need to go as different commands e.g.:
NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"
The expansion $NAME
to empty string is done by the shell earlier, before running echo
, so at the time the NAME
variable is passed to the echo
command's environment, the expansion is already done (to null string).
To get the same result in one command:
NAME=sam printenv NAME
Way 1: only works for dataURL, not for other types of url.
function dataURLtoFile(dataurl, filename) {
var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
while(n--){
u8arr[n] = bstr.charCodeAt(n);
}
return new File([u8arr], filename, {type:mime});
}
//Usage example:
var file = dataURLtoFile('data:image/png;base64,......', 'a.png');
console.log(file);
Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)
//return a promise that resolves with a File instance
function urltoFile(url, filename, mimeType){
mimeType = mimeType || (url.match(/^data:([^;]+);/)||'')[1];
return (fetch(url)
.then(function(res){return res.arrayBuffer();})
.then(function(buf){return new File([buf], filename, {type:mimeType});})
);
}
//Usage example:
urltoFile('data:image/png;base64,......', 'a.png')
.then(function(file){
console.log(file);
})
Both works in Chrome and Firefox.
Try to replace all the " and ' with a \ before them. Do this just for the msget object(String, I guess). Don't forget that \ must be escaped too.
The SublimeText 3 Column-Select plugin should be all you need. Install that, then make sure you have something like the following in your 'Default (OSX).sublime-keymap' file:
// Column mode
{ "keys": ["ctrl+alt+up"], "command": "column_select", "args": {"by": "lines", "forward": false}},
{ "keys": ["ctrl+alt+down"], "command": "column_select", "args": {"by": "lines", "forward": true}},
{ "keys": ["ctrl+alt+pageup"], "command": "column_select", "args": {"by": "pages", "forward": false}},
{ "keys": ["ctrl+alt+pagedown"], "command": "column_select", "args": {"by": "pages", "forward": true}},
{ "keys": ["ctrl+alt+home"], "command": "column_select", "args": {"by": "all", "forward": false}},
{ "keys": ["ctrl+alt+end"], "command": "column_select", "args": {"by": "all", "forward": true}}
What exactly about it did not work for you?
What about scipy.interpolate.splrep (with degree 1 and no smoothing):
>> tck = scipy.interpolate.splrep([1, 2, 3, 4, 5], [1, 4, 9, 16, 25], k=1, s=0)
>> scipy.interpolate.splev(6, tck)
34.0
It seems to do what you want, since 34 = 25 + (25 - 16).
Also seem pdfjam: http://www2.warwick.ac.uk/fac/sci/statistics/staff/academic/firth/software/pdfjam/
match_var = a==b
that should more than suffice
you cant use a - in a variable name as it thinks that is match
(minus) var
match=1
var=2
print match-var #prints -1
if you have lower version and getting problem importing project with high gradle version and want to run the project without updating gradle than
open your gradle file(Project) and do the small change
dependencies {
/*Higher Gradle version*/
// classpath 'com.android.tools.build:gradle:3.0.0-alpha4'
/*Add this line and remove the Higher one*/
classpath 'com.android.tools.build:gradle:2.3.3'
}
[2.3.3 is stand for your gradle version]
in your case change version to 3.2 or 3.2.0 something like that

I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.
With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:
|--------|-------------------|
| P(dBm) | P(mW) |
|--------|-------------------|
| 50 | 100000 |
| 40 | 10000 | strong transmitter
| 30 | 1000 | ^
| 20 | 100 | |
| 10 | 10 | |
| 0 | 1 |
| -10 | 0.1 |
| -20 | 0.01 |
| -30 | 0.001 |
| -40 | 0.0001 |
| -50 | 0.00001 | |
| -60 | 0.000001 | |
| -70 | 0.0000001 | v
| -80 | 0.00000001 | sensitive receiver
| -90 | 0.000000001 |
|--------|-------------------|
When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.
When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.
Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).
For each conflicted file you get, you can specify
git checkout --ours -- <paths>
# or
git checkout --theirs -- <paths>
From the git checkout
docs
git checkout [-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...
--ours
--theirs
When checking out paths from the index, check out stage #2 (ours
) or #3 (theirs
) for unmerged paths.The index may contain unmerged entries because of a previous failed merge. By default, if you try to check out such an entry from the index, the checkout operation will fail and nothing will be checked out. Using
-f
will ignore these unmerged entries. The contents from a specific side of the merge can be checked out of the index by using--ours
or--theirs
. With-m
, changes made to the working tree file can be discarded to re-create the original conflicted merge result.
Just for grins, and in case somebody else runs into a similar error:
I got the infamous "missing separator" error because I had invoked a rule defining a function as
($eval $(call function,args))
rather than
$(eval $(call function,args))
i.e. ($
rather than $(

If you're on Django 1.10 or newer AND Postgres as your database, you can use ArrayField. It's better to use than django-taggit
or other alternatives, as it's native to the Django framework.
https://docs.djangoproject.com/en/3.1/ref/contrib/postgres/fields/#arrayfield
from django.db import models
from django.contrib.postgres.fields import ArrayField
class ChessBoard(models.Model):
board = ArrayField(
ArrayField(
models.CharField(max_length=10, blank=True),
size=8,
),
size=8,
)
If you're on Django 3.1 or newer they've added support for JSONField with most database backends (MariaDB 10.2.7+, MySQL 5.7.8+, Oracle, PostgreSQL, and SQLite 3.9.0+). You can use this to store your Array!
https://docs.djangoproject.com/en/3.1/ref/models/fields/#jsonfield
from django.db import models
class ChessBoard(models.Model):
list_of_pieces = models.JSONField()
You can access the USB drive by its drive letter. To know the drive letter you can run this command:
C:\>wmic logicaldisk where drivetype=2 get deviceid, volumename, description
From here you will get the drive letter (Device ID) of your USB drive.
For example if its F: then run the following command in command prompt to see its contents:
C:\> F:
F:\> dir
set escape on
... node_name = 'Geometric Vectors \& Matrices' ...
or alternatively:
set define off
... node_name = 'Geometric Vectors & Matrices' ...
The first allows you to use the backslash to escape the &.
The second turns off & "globally" (no need to add a backslash anywhere). You can turn it on again by set define on
and from that line on the ampersands will get their special meaning back, so you can turn it off for some parts of the script and not for others.
every approach above includes a lot more work than this one AFAICT...
( mysqldump --add-drop-table --no-data -u root -p database | grep 'DROP TABLE' ) > ./drop_all_tables.sql
mysql -u root -p database < ./drop_all_tables.sql
The above method for Visual Studio didn't seem to apply to Visual Studio 2013, but I was able to find the described checkbox using the Project Menu and selecting my project (probably the last item on the submenu) to get to the dialog with the checkbox (on the Build tab).
For converting a list of dictionaries to a pandas DataFrame, you can use "append":
We have a dictionary called dic
and dic has 30 list items (list1
, list2
,…, list30
)
total_df
)total_df
with list1
total_df
total_df=list1
nums=Series(np.arange(start=2, stop=31))
for num in nums:
total_df=total_df.append(dic['list'+str(num)])
This is how I did a similar thing. I have tiles that are thumbnails to YouTube videos. When I click the tile, it redirects me to a 'player' page that uses the 'video_id' to render the correct video to the page.
<GridTile
key={video_id}
title={video_title}
containerElement={<Link to={`/player/${video_id}`}/>}
>
ETA: Sorry, just noticed that you didn't want to use the LINK or REDIRECT components for some reason. Maybe my answer will still help in some way. ; )
If you are able to run a script, here is what I did for a similar situation:
Using a dictionary/hashMap (associative array) and variables for the sed
command, we can loop through the array to replace several strings. Including a wildcard in the name_pattern
will allow to replace in-place in files with a pattern (this could be something like name_pattern='File*.txt'
) in a specific directory (source_dir
).
All the changes are written in the logfile
in the destin_dir
#!/bin/bash
source_dir=source_path
destin_dir=destin_path
logfile='sedOutput.txt'
name_pattern='File.txt'
echo "--Begin $(date)--" | tee -a $destin_dir/$logfile
echo "Source_DIR=$source_dir destin_DIR=$destin_dir "
declare -A pairs=(
['WHAT1']='FOR1'
['OTHER_string_to replace']='string replaced'
)
for i in "${!pairs[@]}"; do
j=${pairs[$i]}
echo "[$i]=$j"
replace_what=$i
replace_for=$j
echo " "
echo "Replace: $replace_what for: $replace_for"
find $source_dir -name $name_pattern | xargs sed -i "s/$replace_what/$replace_for/g"
find $source_dir -name $name_pattern | xargs -I{} grep -n "$replace_for" {} /dev/null | tee -a $destin_dir/$logfile
done
echo " "
echo "----End $(date)---" | tee -a $destin_dir/$logfile
First, the pairs array is declared, each pair is a replacement string, then WHAT1
will be replaced for FOR1
and OTHER_string_to replace
will be replaced for string replaced
in the file File.txt
. In the loop the array is read, the first member of the pair is retrieved as replace_what=$i
and the second as replace_for=$j
. The find
command searches in the directory the filename (that may contain a wildcard) and the sed -i
command replaces in the same file(s) what was previously defined. Finally I added a grep
redirected to the logfile to log the changes made in the file(s).
This worked for me in GNU Bash 4.3
sed 4.2.2
and based upon VasyaNovikov's answer for Loop over tuples in bash.
Instead of
Image.open(picture.jpg)
Img.show
You should have
from PIL import Image
#...
img = Image.open('picture.jpg')
img.show()
You should probably also think about an other system to show your messages, because this way it will be a lot of manual work. Look into string substitution (using %s
or .format()
).
I have found the answer to this, and it is annoyingly/frustratingly simple! Basically the reply to addresses needed to be added before the from address as such:
$mail->addReplyTo('[email protected]', 'Reply to name');
$mail->SetFrom('[email protected]', 'Mailbox name');
Looking at the phpmailer code in more detail this is the offending line:
public function SetFrom($address, $name = '',$auto=1) {
$address = trim($address);
$name = trim(preg_replace('/[\r\n]+/', '', $name)); //Strip breaks and trim
if (!self::ValidateAddress($address)) {
$this->SetError($this->Lang('invalid_address').': '. $address);
if ($this->exceptions) {
throw new phpmailerException($this->Lang('invalid_address').': '.$address);
}
echo $this->Lang('invalid_address').': '.$address;
return false;
}
$this->From = $address;
$this->FromName = $name;
if ($auto) {
if (empty($this->ReplyTo)) {
$this->AddAnAddress('ReplyTo', $address, $name);
}
if (empty($this->Sender)) {
$this->Sender = $address;
}
}
return true;
}
Specifically this line:
if (empty($this->ReplyTo)) {
$this->AddAnAddress('ReplyTo', $address, $name);
}
Thanks for your help everyone!
For anyone who finds this page looking for unix timestamp w/ milliseconds, the documentation says
moment().valueOf()
or
+moment();
you can also get it through moment().format('x')
(or .format('X')
[capital X] for unix seconds with decimal milliseconds), but that will give you a string. Which moment.js won't actually parse back afterwards, unless you convert/cast it back to a number first.
string startTime = "7:00 AM";
string endTime = "2:00 PM";
TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
Console.WriteLine(duration);
Console.ReadKey();
Will output: 07:00:00.
It also works if the user input military time:
string startTime = "7:00";
string endTime = "14:00";
TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
Console.WriteLine(duration);
Console.ReadKey();
Outputs: 07:00:00.
To change the format: duration.ToString(@"hh\:mm")

Addendum:
Over the years it has somewhat bothered me that this is the most popular answer I have ever given; the original answer never actually explained why the OP's code didn't work despite the fact that it is perfectly valid. The only reason it gets so many votes is because the post comes up on Google when people search for a combination of the terms "C#", "timespan", and "between".
This happened to me also. And I found the javaw.exe in C:\Windows\System32 got deleted after the windows update. Copied one more time and Eclipse started all fine.

Configure NLog via XML, but Programmatically
What? Did you know that you can specify the NLog XML directly to NLog from your app, as opposed to having NLog read it from the config file? Well, you can. Let's say that you have a distributed app and you want to use the same configuration everywhere. You could keep a config file in each location and maintain it separately, you could maintain one in a central location and push it out to the satellite locations, or you could probably do a lot of other things. Or, you could store your XML in a database, get it at app startup, and configure NLog directly with that XML (maybe checking back periodically to see if it had changed).
string xml = @"<nlog>
<targets>
<target name='console' type='Console' layout='${message}' />
</targets>
<rules>
<logger name='*' minlevel='Error' writeTo='console' />
</rules>
</nlog>";
StringReader sr = new StringReader(xml);
XmlReader xr = XmlReader.Create(sr);
XmlLoggingConfiguration config = new XmlLoggingConfiguration(xr, null);
LogManager.Configuration = config;
//NLog is now configured just as if the XML above had been in NLog.config or app.config
logger.Trace("Hello - Trace"); //Won't log
logger.Debug("Hello - Debug"); //Won't log
logger.Info("Hello - Info"); //Won't log
logger.Warn("Hello - Warn"); //Won't log
logger.Error("Hello - Error"); //Will log
logger.Fatal("Hello - Fatal"); //Will log
//Now let's change the config (the root logging level) ...
string xml2 = @"<nlog>
<targets>
<target name='console' type='Console' layout='${message}' />
</targets>
<rules>
<logger name='*' minlevel='Trace' writeTo='console' />
</rules>
</nlog>";
StringReader sr2 = new StringReader(xml2);
XmlReader xr2 = XmlReader.Create(sr2);
XmlLoggingConfiguration config2 = new XmlLoggingConfiguration(xr2, null);
LogManager.Configuration = config2;
logger.Trace("Hello - Trace"); //Will log
logger.Debug("Hello - Debug"); //Will log
logger.Info("Hello - Info"); //Will log
logger.Warn("Hello - Warn"); //Will log
logger.Error("Hello - Error"); //Will log
logger.Fatal("Hello - Fatal"); //Will log
I'm not sure how robust this is, but this example provides a useful starting point for people that might want to try configuring like this.
I know this is an old question but anyway it might help someone.
I tend to use PHP_EOL
for this purposes (due to cross-platform compatibility).
echo "line 1".PHP_EOL."line 2".PHP_EOL;

I also faced the same problem and the problem was that the libraries were missing in some of the following files.
settings.gradle, app/build.gradle, package.json, MainApplication.java
Suppose the library is react-native-vector-icons then it should be mentioned in following files;
compile project(':react-native-vector-icons')
include ':react-native-vector-icons' project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')
Import the dependency: import com.oblador.vectoricons.VectorIconsPackage;
and then add: new VectorIconsPackage() in getPackages() method.
Simple, but effective!
Math.floor(number) === number;
I have string that displays UTF-8 encoded characters
There is no such thing in .NET. The string class can only store strings in UTF-16 encoding. A UTF-8 encoded string can only exist as a byte[]. Trying to store bytes into a string will not come to a good end; UTF-8 uses byte values that don't have a valid Unicode codepoint. The content will be destroyed when the string is normalized. So it is already too late to recover the string by the time your DecodeFromUtf8() starts running.
Only handle UTF-8 encoded text with byte[]. And use UTF8Encoding.GetString() to convert it.
Since none of the suggestions above helped me with charts.js 2.1.4, I solved it by adding the value 0 to my data set array (but no extra label):

I wasn't satisfied with the rounded top and bottom to the shadow present in Deefour's solution so created my own.
inset
box-shadow
creates a nice uniform shadow with the top and bottom cut off.
To use this effect on the sides of your element, create two pseudo elements :before
and :after
positioned absolutely on the sides of the original element.
div:before, div:after {
content: " ";

Edit
Depending on your design, you may be able to use clip-path
, as shown in @Luke's answer. However, note that in many cases this still results in the shadow tapering off at the top and bottom as you can see in this example:
div {
width: 100px;
height: 100px;
background: #EEE;
box-shadow: 0 0 15px 0px #000;
clip-path: inset(0px -15px 0px -15px);
position: relative;
margin: 0 50px;
}

global $post;
echo $post->ID;
I know it's an old topic but still. I've just met the problem in the code I am debugging at work and maybe somebody may have similar issue...
Let's say the code looks like this:
$positions = $this->positions() || [];
You would expect (as you are used to from e.g. javascript) that when $this->positions() returns false or null, $positions is empty array. But it isn't. The value is TRUE or FALSE depends on what $this->positions() returns.
If you need to get value of $this->positions() or empty array, you have to use:
$positions = $this->positions() or [];
EDIT:
The above example doesn't work as intended but the truth is that ||
and or
is not the same... Try this:
<?php
function returnEmpty()
{
//return "string";
//return [1];
return null;
}
$first = returnEmpty() || [];
$second = returnEmpty() or [];
$third = returnEmpty() ?: [];
var_dump($first);
var_dump($second);
var_dump($third);
echo "\n";
This is the result:
bool(false)
NULL
array(0) {
}
So, actually the third option ?:
is the correct solution when you want to set returned value or empty array.
$positions = $this->positions() ?: [];
Tested with PHP 7.2.1
You can use $(!!)
to recompute (not re-use) the output of the last command.
The !!
on its own executes the last command.
$ echo pierre
pierre
$ echo my name is $(!!)
echo my name is $(echo pierre)
my name is pierre
//create a file handler by opening the file
$myTextFileHandler = @fopen("filelist.txt","r+");
//truncate the file to zero
//or you could have used the write method and written nothing to it
@ftruncate($myTextFileHandler, 0);
//use location header to go back to index.html
header("Location:index.html");
I don't exactly know where u want to show the result.
It's not possible with Notepad but HERE'S THE EASY SOLUTION:
You will need the freeware Expresso v3.1 http://www.ultrapico.com/ExpressoDownload.htm
I resorted to another piece of free software: Expresso by Ultrapico.
Paste your whole text to be searched into the "Sample text" pane of Expresso,
Press the "Run match" button. Right click in the "Search results pane" and "Export to..." or "Copy matched text to clipboard".
N.B.: The original author is @Andreas Jansson but it is hidden in a comment, so since this page is high ranked in Google Search I leave it here for others.
If you have anything in particular you want to hide (like a proprietary algorithm), put that on the server, or put it in a Flash movie and call it with JavaScript. Writing ActionScript is very similar to writing JavaScript, and you can communicate between JavaScript and ActionScript. You can do the same with Silverlight, but Silverlight doesn't have the penetration Flash does.
However, remember that any mobile phones can run your JavaScript, but not Silverlight or Flash, so you're crippling your mobile users if you go with Flash or Silverlight.
If all that you want is to see the disassembly with the INTC call, use objdump -d as someone mentioned but use the -static option when compiling. Otherwise the fopen function is not compiled into the elf and is linked at runtime.
In your second part, you should use new = original.copy()
.copy
and =
are different things.
/^\d{4}$/ This will check if a string consists of only 4 numbers. In this scenario, to input a year 989, you can give 0989 instead.
name
field works well. It provides a reference to the elements
.
parent.children
- Will list all elements with a name field of the parent.
parent.elements
- Will list only form elements
such as input-text, text-area, etc
var form = document.getElementById('form-1');_x000D_
console.log(form.children.firstname)_x000D_
console.log(form.elements.firstname)_x000D_
console.log(form.elements.progressBar); // undefined_x000D_
console.log(form.children.progressBar);_x000D_
console.log(form.elements.submit); // undefined
_x000D_
<form id="form-1">_x000D_
<input type="text" name="firstname" />_x000D_
<input type="file" name="file" />_x000D_
<progress name="progressBar" value="20" min="0" max="100" />_x000D_
<textarea name="address"></textarea>_x000D_
<input type="submit" name="submit" />_x000D_
</form>
_x000D_
Note: For .elements
to work, the parent
needs to be a <form> tag
. Whereas, .children
will work on any HTML-element
- such as <div>, <span>, etc
.
Good Luck...
There's one issue with using self.title = @"title";
If you're using Navigation Bar along with Tab bar, the above line also changes the label for the Tab Bar Item. To avoid this, use what @testing suggested
self.navigationItem.title = @"MyTitle";
It seems you need DataFrame.var
:
Normalized by N-1 by default. This can be changed using the ddof argument
var1 = credit_card.var()
Sample:
#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
A B C D E
0 8 8 3 7 7
1 0 4 2 5 2
2 2 2 1 0 8
3 4 0 9 6 2
4 4 1 5 3 4
var1 = credit_card.var()
print (var1)
A 8.8
B 10.0
C 10.0
D 7.7
E 7.8
dtype: float64
var2 = credit_card.var(axis=1)
print (var2)
0 4.3
1 3.8
2 9.8
3 12.2
4 2.3
dtype: float64
If need numpy solutions with numpy.var
:
print (np.var(credit_card.values, axis=0))
[ 7.04 8. 8. 6.16 6.24]
print (np.var(credit_card.values, axis=1))
[ 3.44 3.04 7.84 9.76 1.84]
Differences are because by default ddof=1
in pandas
, but you can change it to 0
:
var1 = credit_card.var(ddof=0)
print (var1)
A 7.04
B 8.00
C 8.00
D 6.16
E 6.24
dtype: float64
var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0 3.44
1 3.04
2 7.84
3 9.76
4 1.84

I guess you're using windows 7 with the Orwell Dev CPP
This version of Dev CPP is good for windows 8 only. However on Windows 7 you need the older version of it which is devcpp-4.9.9.2_setup.exe Download it from the link and use it. (Don't forget to uninstall any other version already installed on your pc) Also note that the older version does not work with windows 8.

connect the mysql database by installing a library. here, picked the stable and easy to use node-mysql module.
npm install [email protected]

System.out.println(b.equals(a) ? "equal" : "different");
System.out.println((long) b == a ? "equal" : "different");
list.append
returns None
, since it is an in-place operation and you are assigning it back to dates_dict[key]
. So, the next time when you do dates_dict.get(key, []).append
you are actually doing None.append
. That is why it is failing. Instead, you can simply do
dates_dict.setdefault(key, []).append(date)
But, we have collections.defaultdict
for this purpose only. You can do something like this
from collections import defaultdict
dates_dict = defaultdict(list)
for key, date in cur:
dates_dict[key].append(date)
This will create a new list object, if the key
is not found in the dictionary.
Note: Since the defaultdict
will create a new list if the key is not found in the dictionary, this will have unintented side-effects. For example, if you simply want to retrieve a value for the key, which is not there, it will create a new list and return it.

Referring to @dylanvanw answer. You might still out of luck. I found that you might have a different path that you have installed Python. In my case, I have to move Chromedriver.exe from the cache path (C:\Users\Poom.wdm\drivers\chromedriver\win32\84.0.4147.30) to C:\Python38 then it work!
Use this to get an admin window with either bash or cmd running, from any directories context menue. Just right click on a directory name, and select the entry or hit the highlited button.
This is based on the chere tool and the unfortunately not working answer (for me) from link_boy. It works fine for me using Windows 8,
A side effect is the different color in the admin cmd window. To use this on bash, you can change the .bashrc file of the admin user.
I coudln't get the "background" version (right click into an open directory) to run. Feel free to add it.

Since you added a new property to the model, you must first delete the database. Then manage.py migrations then manage.py migrate.
As I don't plan to support old MS IE versions at all, I've simply replaced all references to browser.msie
with false
.
Not a nice solution, I know, but it works for me.
(Actually, they appeared as !browser.msie
, which could be omitted from the conditions.)
Try using the data
option of the $.ajax
function. More info here.
$('#btnSaveComments').click(function () {
var comments = $('#txtComments').val();
var selectedId = $('#hdnSelectedId').val();
$.ajax({
url: '<%: Url.Action("SaveComments")%>',
data: { 'id' : selectedId, 'comments' : comments },
type: "post",
cache: false,
success: function (savingStatus) {
$("#hdnOrigComments").val($('#txtComments').val());
$('#lblCommentsNotification').text(savingStatus);
},
error: function (xhr, ajaxOptions, thrownError) {
$('#lblCommentsNotification').text("Error encountered while saving the comments.");
}
});
});
You can try the Class Based View called RedirectView
from django.views.generic.base import RedirectView
urlpatterns = patterns('',
url(r'^$', 'macmonster.views.home'),
#url(r'^macmon_home$', 'macmonster.views.home'),
url(r'^macmon_output/$', 'macmonster.views.output'),
url(r'^macmon_about/$', 'macmonster.views.about'),
url(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
)
Notice how as url
in the <url_to_home_view>
you need to actually specify the url.
permanent=False
will return HTTP 302, while permanent=True
will return HTTP 301.
Alternatively you can use django.shortcuts.redirect
Update for Django 2+ versions
With Django 2+, url()
is deprecated and replaced by re_path()
. Usage is exactly the same as url()
with regular expressions. For replacements without the need of regular expression, use path()
.
from django.urls import re_path
re_path(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
While writing my own object.IsNumeric()
extension method based on Saul Dolgin's answer to this question I ran into a potential issue in that you will get an OverflowException
if you try it with double.MaxValue
or double.MinValue
.
My "solution" was to combine the accepted answer from Noldorin with the one from Saul Dolgin and add a pattern matching switch before trying to parse anything (and use some C#7 goodness to tidy up a bit):
public static bool IsNumeric(this object obj)
{
if (obj == null) return false;
switch (obj)
{
case sbyte _: return true;
case byte _: return true;
case short _: return true;
case ushort _: return true;
case int _: return true;
case uint _: return true;
case long _: return true;
case ulong _: return true;
case float _: return true;
case double _: return true;
case decimal _: return true;
}
string s = Convert.ToString(obj, CultureInfo.InvariantCulture);
return double.TryParse(s, NumberStyles.Any, NumberFormatInfo.InvariantInfo, out double _);
}
Make sure the target window that you (or Facebook) is posting a message to, has completed loading. Most of the times I've gotten this error were when an iframe I was sending messages to had failed to load.
In my case, I was getting value of <input type="text">
with JQuery and I did it like this:
var newUserInfo = { "lastName": inputLastName[0].value, "userName": inputUsername[0].value,
"firstName": inputFirstName[0] , "email": inputEmail[0].value}
And I was constantly getting this exception
com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_OBJECT token at [Source: java.io.PushbackInputStream@39cb6c98; line: 1, column: 54] (through reference chain: com.springboot.domain.User["firstName"]).
And I banged my head for like an hour until I realised that I forgot to write .value
after this"firstName": inputFirstName[0]
.
So, the correct solution was:
var newUserInfo = { "lastName": inputLastName[0].value, "userName": inputUsername[0].value,
"firstName": inputFirstName[0].value , "email": inputEmail[0].value}
I came here because I had this problem and I hope I save someone else hours of misery.
Cheers :)
This one liner replaces all the ^M characters:
dos2unix <file-name>
You can call this from inside Perl or directly on your Unix prompt.
You are trying to decode an object that is already decoded. You have a str
, there is no need to decode from UTF-8 anymore.
Simply drop the .decode('utf-8')
part:
header_data = data[1][0][1]
As for your fetch()
call, you are explicitly asking for just the first message. Use a range if you want to retrieve more messages. See the documentation:
The message_set options to commands below is a string specifying one or more messages to be acted upon. It may be a simple message number (
'1'
), a range of message numbers ('2:4'
), or a group of non-contiguous ranges separated by commas ('1:3,6:9'
). A range can contain an asterisk to indicate an infinite upper bound ('3:*'
).
The following regex will work for both:
text = text.replaceAll("('|\")", "\\\\$1");
These examples are fine, I wanted to point out that you can achieve the same result using an Intent. The intent opens the Contacts app with the fields you provide already filled in.
It's up to the user to save the newly created contact.
You can read about it here: https://developer.android.com/training/contacts-provider/modify-data.html
Intent contactIntent = new Intent(ContactsContract.Intents.Insert.ACTION);
contactIntent.setType(ContactsContract.RawContacts.CONTENT_TYPE);
contactIntent
.putExtra(ContactsContract.Intents.Insert.NAME, "Contact Name")
.putExtra(ContactsContract.Intents.Insert.PHONE, "5555555555");
startActivityForResult(contactIntent, 1);
startActivityForResult() gives you the opportunity to see the result.
I've noticed the resultCode works on >5.0 devices,
but I have an older Samsung (<5) that always returns RESULT_CANCELLED (0).
Which I understand is the default return if an activity doesn't expect to return anything.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (requestCode == 1)
{
if (resultCode == Activity.RESULT_OK) {
Toast.makeText(this, "Added Contact", Toast.LENGTH_SHORT).show();
}
if (resultCode == Activity.RESULT_CANCELED) {
Toast.makeText(this, "Cancelled Added Contact", Toast.LENGTH_SHORT).show();
}
}
}

You can use laravel MessageBag to add our own messages to existing messages.
To use MessageBag you need to use:
use Illuminate\Support\MessageBag;
In the controller:
MessageBag $message_bag
$message_bag->add('message', trans('auth.confirmation-success'));
return redirect('login')->withSuccess($message_bag);
Hope it will help some one.
Use the split function.
static void Main(string[] args)
{
string s = "223232-1.jpg";
Console.WriteLine(s.Split('-')[0]);
s = "443-2.jpg";
Console.WriteLine(s.Split('-')[0]);
s = "34443553-5.jpg";
Console.WriteLine(s.Split('-')[0]);
Console.ReadKey();
}
If your string doesn't have a -
then you'll get the whole string.
It's explained in great detail in the docs, but I'll try to summarize:
matching
means git push
will push all your local branches to the ones with the same name on the remote. This makes it easy to accidentally push a branch you didn't intend to.
simple
means git push
will push only the current branch to the one that git pull
would pull from, and also checks that their names match. This is a more intuitive behavior, which is why the default is getting changed to this.
This setting only affects the behavior of your local client, and can be overridden by explicitly specifying which branches you want to push on the command line. Other clients can have different settings, it only affects what happens when you don't specify which branches you want to push.
After making changes to the pg_hba.conf
or postgresql.conf
files, the cluster needs to be reloaded to pick up the changes.
From the command line: pg_ctl reload
From within a db (as superuser): select pg_reload_conf();
From PGAdmin: right-click db name, select "Reload Configuration"
Note: the reload is not sufficient for changes like enabling archiving, changing shared_buffers
, etc -- those require a cluster restart.

It should be noted that the documentation recommends using a Layout
rather than Canvas.drawText
directly. My full answer about using a StaticLayout
is here, but I will provide a summary below.
String text = "This is some text.";
TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);
int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);
Here is a fuller example in the context of a custom view:
public class MyView extends View {
String mText = "This is some text.";
TextPaint mTextPaint;
StaticLayout mStaticLayout;
// use this constructor if creating MyView programmatically
public MyView(Context context) {
super(context);
initLabelView();
}
// this constructor is used when created from xml
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
initLabelView();
}
private void initLabelView() {
mTextPaint = new TextPaint();
mTextPaint.setAntiAlias(true);
mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
mTextPaint.setColor(0xFF000000);
// default to a single line of text
int width = (int) mTextPaint.measureText(mText);
mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
// New API alternate
//
// StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
// .setAlignment(Layout.Alignment.ALIGN_NORMAL)
// .setLineSpacing(1, 0) // multiplier, add
// .setIncludePad(false);
// mStaticLayout = builder.build();
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Tell the parent layout how big this view would like to be
// but still respect any requirements (measure specs) that are passed down.
// determine the width
int width;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
if (widthMode == MeasureSpec.EXACTLY) {
width = widthRequirement;
} else {
width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
if (widthMode == MeasureSpec.AT_MOST) {
if (width > widthRequirement) {
width = widthRequirement;
// too long for a single line so relayout as multiline
mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
}
}
}
// determine the height
int height;
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
if (heightMode == MeasureSpec.EXACTLY) {
height = heightRequirement;
} else {
height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
if (heightMode == MeasureSpec.AT_MOST) {
height = Math.min(height, heightRequirement);
}
}
// Required call: set width and height
setMeasuredDimension(width, height);
}

Writing a decorator that works with and without parameter is a challenge because Python expects completely different behavior in these two cases! Many answers have tried to work around this and below is an improvement of answer by @norok2. Specifically, this variation eliminates the use of locals()
.
Following the same example as given by @norok2:
import functools
def multiplying(f_py=None, factor=1):
assert callable(f_py) or f_py is None
def _decorator(func):
@functools.wraps(func)
def wrapper(*args, **kwargs):
return factor * func(*args, **kwargs)
return wrapper
return _decorator(f_py) if callable(f_py) else _decorator
@multiplying
def summing(x): return sum(x)
print(summing(range(10)))
# 45
@multiplying()
def summing(x): return sum(x)
print(summing(range(10)))
# 45
@multiplying(factor=10)
def summing(x): return sum(x)
print(summing(range(10)))
# 450
The catch is that the user must supply key,value pairs of parameters instead of positional parameters and the first parameter is reserved.
Just a small addition to Nick's answer (which works great !) :
If you want to allow spaces in between letters, for example , you may restrict to enter only letters in full name, but it should allow space as well - just list the space as below with a comma. And in the same way if you need to allow any other specific character:
jQuery.validator.addMethod("lettersonly", function(value, element)
{
return this.optional(element) || /^[a-z," "]+$/i.test(value);
}, "Letters and spaces only please");
Install Entity framework to the current project using the below command: PM> Install-Package EntityFramework -IncludePrerelease
Add a class "MyDBContext" in the Model folder as given below:
public class MyDBContext : DbContext { public MyDBContext() { } }
Now enable migrations for the current project with the below command: PM> enable-migrations
Maybe
SELECT count(*) FROM (
SELECT COUNT(*) FROM Movies GROUP BY ID HAVING count(Genre) = 4
) AS the_count_total
although that would not be the sum of all the movies, just how many have 4 genre's.
So maybe you want
SELECT sum(
SELECT COUNT(*) FROM Movies GROUP BY ID having Count(Genre) = 4
) as the_sum_total
When the JVM loads classes, or otherwise sees a literal string, or some code intern
s a string, it adds the string to a mostly-hidden lookup table that has one copy of each such string. If another copy is added, the runtime arranges it so that all the literals refer to the same string object. This is called "interning". If you say something like
String s = "test";
return (s == "test");
it'll return true
, because the first and second "test" are actually the same object. Comparing interned strings this way can be much, much faster than String.equals
, as there's a single reference comparison rather than a bunch of char
comparisons.
You can add a string to the pool by calling String.intern()
, which will give you back the pooled version of the string (which could be the same string you're interning, but you'd be crazy to rely on that -- you often can't be sure exactly what code has been loaded and run up til now and interned the same string). The pooled version (the string returned from intern
) will be equal to any identical literal. For example:
String s1 = "test";
String s2 = new String("test"); // "new String" guarantees a different object
System.out.println(s1 == s2); // should print "false"
s2 = s2.intern();
System.out.println(s1 == s2); // should print "true"
Two options:
for (let item in MotifIntervention) {
if (isNaN(Number(item))) {
console.log(item);
}
}
Or
Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));
String enums look different than regular ones, for example:
enum MyEnum {
A = "a",
B = "b",
C = "c"
}
Compiles into:
var MyEnum;
(function (MyEnum) {
MyEnum["A"] = "a";
MyEnum["B"] = "b";
MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));
Which just gives you this object:
{
A: "a",
B: "b",
C: "c"
}
You can get all the keys (["A", "B", "C"]
) like this:
Object.keys(MyEnum);
And the values (["a", "b", "c"]
):
Object.keys(MyEnum).map(key => MyEnum[key])
Or using Object.values():
Object.values(MyEnum)
Kubernetes is an open source project that brings 'Google style' cluster management capabilities to the world of virtual machines, or 'on the metal' scenarios. It works very well with modern operating system environments (like CoreOS or Red Hat Atomic) that offer up lightweight computing 'nodes' that are managed for you. It is written in Golang and is lightweight, modular, portable and extensible. We (the Kubernetes team) are working with a number of different technology companies (including Mesosphere who curate the Mesos open source project) to establish Kubernetes as the standard way to interact with computing clusters. The idea is to reproduce the patterns that we see people needing to build cluster applications based on our experience at Google. Some of these concepts include:
So with Kubernetes alone you will have something that is simple, easy to get up-and-running, portable and extensible that adds 'cluster' as a noun to the things that you manage in the lightest weight manner possible. Run an application on a cluster, and stop worrying about an individual machine. In this case, cluster is a flexible resource just like a VM. It is a logical computing unit. Turn it up, use it, resize it, turn it down quickly and easily.
With Mesos, there is a fair amount of overlap in terms of the basic vision, but the products are at quite different points in their lifecycle and have different sweet spots. Mesos is a distributed systems kernel that stitches together a lot of different machines into a logical computer. It was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application run well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps. It is somewhat more heavy weight than the Kubernetes project, but is getting easier and easier to manage thanks to the work of folks like Mesosphere.
Now what gets really interesting is that Mesos is currently being adapted to add a lot of the Kubernetes concepts and to support the Kubernetes API. So it will be a gateway to getting more capabilities for your Kubernetes app (high availability master, more advanced scheduling semantics, ability to scale to a very large number of nodes) if you need them, and is well suited to run production workloads (Kubernetes is still in an alpha state).
When asked, I tend to say:
Kubernetes is a great place to start if you are new to the clustering world; it is the quickest, easiest and lightest way to kick the tires and start experimenting with cluster oriented development. It offers a very high level of portability since it is being supported by a lot of different providers (Microsoft, IBM, Red Hat, CoreOs, MesoSphere, VMWare, etc).
If you have existing workloads (Hadoop, Spark, Kafka, etc), Mesos gives you a framework that let's you interleave those workloads with each other, and mix in a some of the new stuff including Kubernetes apps.
Mesos gives you an escape valve if you need capabilities that are not yet implemented by the community in the Kubernetes framework.
Here's some full and simple code to do this. This worked fine when I used it.
var processStartInfo = new ProcessStartInfo
{
FileName = @"C:\SomeProgram",
Arguments = "Arguments",
RedirectStandardOutput = true,
UseShellExecute = false
};
var process = Process.Start(processStartInfo);
var output = process.StandardOutput.ReadToEnd();
process.WaitForExit();
Note that this only captures standard output; it doesn't capture standard error. If you want both, use this technique for each stream.
You can add Connection Timeout=180;
to your connection string
you have parse that Json
string using JSON.parse()
..
}).done(function(data){
obj = JSON.parse(data);
alert(obj.jobtitel);
});
If anyone came here trying to do this with a decimal like me:
myFloat = parseFloat(myString);
If you just need an Int, that's well covered in the other answers.
Even if it s late i hope i can help someone. if dropdown menu or submenu is on the right side of screen it's open on the left side, if menu or submenu is on the left it's open on the right side.
$(".dropdown-toggle").on("click", function(event){//"show.bs.dropdown"
var liparent=$(this.parentElement);
var ulChild=liparent.find('ul');
var xOffset=liparent.offset().left;
var alignRight=($(document).width()-xOffset)<xOffset;
if (liparent.hasClass("dropdown-submenu"))
{
ulChild.css("left",alignRight?"-101%":"");
}
else
{
ulChild.toggleClass("dropdown-menu-right",alignRight);
}
});
To detect vertical position you can also add
$( document ).ready(function() {
var liparent=$(".dropdown");
var yOffset=liparent.offset().top;
var toTop=($(document).height()-yOffset)<yOffset;
liparent.toggleClass("dropup",toTop);
});
Try to use IF(condition, value1, value2)
SELECT ID, HEADING,
IF(action_type='Income',action_amount,0) as Income,
IF(action_type='Expense',action_amount,0) as Expense
I had the same issue. After much searching I decided to reconfigure my server in Eclipse. (ie clean it as suggested by Benson Go to Project Explorer, Servers and Delete (ensure you also delete contents on disk) Then go to Windows->Preferences->Server->Runtime Environments Remove the Tomcat server and then add it back in.
This cleans up the server.xml, webxml, context.xml files. It basically rewrites them. Something in one of mine (or multiple things) were awry and this fixes it. A bit simpler than trying to find the offending tags/lines
You can use ORDER BY
clause to sort data rows by values in columns. Something like
=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C, D")
If you’d like to order by some columns descending, others ascending, you can add desc
/asc
, ie:
=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C desc, D")
It is all about preventing definitions from clashing with other code linked in to your project. It means you can keep things separate.
For example you can have one method called "run" in your code and you will still be able to call your method rather than the "run" method that has been defined in some other library that you have linked in.
You should use new when you want an object to be created on the heap instead of the stack. This allows an object to be accessed from outside the current function or procedure, through the aid of pointers.
It might be of use to you to look up pointers and memory management in C++ since these are things you are unlikely to have come across in other languages.
Country is a categorical variable and I want to see how many occurences of country exist in the data set. In other words, how many records/attendees are from each Country
barplot(summary(df$Country))
First way is
function function1()
{
var variable1=12;
function2(variable1);
}
function function2(val)
{
var variableOfFunction1 = val;
// Then you will have to use this function for the variable1 so it doesn't really help much unless that's what you want to do. }
Second way is
var globalVariable;
function function1()
{
globalVariable=12;
function2();
}
function function2()
{
var local = globalVariable;
}
I checked play.google.com/store/apps/details?id=and.p2l&hl=en They are not locating the user's current location at all. So based on the number itself they are judging the location of the user. Like if the number starts from 240 ( in US) they they are saying location is Maryland but the person can be in California. So i don't think they are getting the user's location through LocationListner of Java at all.
There's pycron which I really as a Cron implementation for windows, but there's also the built in scheduler which should work just fine for what you need (Control Panel -> Scheduled Tasks -> Add Scheduled Task).

If you're on the New Google Sheets, this is all you need to do, according to the docs:
change your recalculation setting to "On change and every minute" in your spreadsheet at File > Spreadsheet settings.
This will make the entire sheet update itself every minute, on the server side, regardless of whether you have the spreadsheet up in your browser or not.
If you're on the old Google Sheets, you'll want to add a cell with this formula to achieve the same functionality:
=GoogleClock()
EDIT to include old and new Google Sheets and change to =GoogleClock()

Here I am going to explain not only the GROUP clause use, but also the Aggregate functions use.
The GROUP BY
clause is used in conjunction with the aggregate functions to group the result-set by one or more columns. e.g.:
-- GROUP BY with one parameter:
SELECT column_name, AGGREGATE_FUNCTION(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name;
-- GROUP BY with two parameters:
SELECT
column_name1,
column_name2,
AGGREGATE_FUNCTION(column_name3)
FROM
table_name
GROUP BY
column_name1,
column_name2;
Remember this order:
SELECT (is used to select data from a database)
FROM (clause is used to list the tables)
WHERE (clause is used to filter records)
GROUP BY (clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns)
HAVING (clause is used in combination with the GROUP BY clause to restrict the groups of returned rows to only those whose the condition is TRUE)
ORDER BY (keyword is used to sort the result-set)
You can use all of these if you are using aggregate functions, and this is the order that they must be set, otherwise you can get an error.
Aggregate Functions are:
MIN() returns the smallest value in a given column
MAX() returns the maximum value in a given column.
SUM() returns the sum of the numeric values in a given column
AVG() returns the average value of a given column
COUNT() returns the total number of values in a given column
COUNT(*) returns the number of rows in a table
SQL script examples about using aggregate functions:
Let's say we need to find the sale orders whose total sale is greater than $950. We combine the HAVING
clause and the GROUP BY
clause to accomplish this:
SELECT
orderId, SUM(unitPrice * qty) Total
FROM
OrderDetails
GROUP BY orderId
HAVING Total > 950;
Counting all orders and grouping them customerID and sorting the result ascendant. We combine the COUNT
function and the GROUP BY
, ORDER BY
clauses and ASC
:
SELECT
customerId, COUNT(*)
FROM
Orders
GROUP BY customerId
ORDER BY COUNT(*) ASC;
Retrieve the category that has an average Unit Price greater than $10, using AVG
function combine with GROUP BY
and HAVING
clauses:
SELECT
categoryName, AVG(unitPrice)
FROM
Products p
INNER JOIN
Categories c ON c.categoryId = p.categoryId
GROUP BY categoryName
HAVING AVG(unitPrice) > 10;
Getting the less expensive product by each category, using the MIN
function in a subquery:
SELECT categoryId,
productId,
productName,
unitPrice
FROM Products p1
WHERE unitPrice = (
SELECT MIN(unitPrice)
FROM Products p2
WHERE p2.categoryId = p1.categoryId)
The following statement groups rows with the same values in both categoryId and productId columns:
SELECT
categoryId, categoryName, productId, SUM(unitPrice)
FROM
Products p
INNER JOIN
Categories c ON c.categoryId = p.categoryId
GROUP BY categoryId, productId
boolean alltrue = true;
for(int i = 0; alltrue && i<booleanArray.length(); i++)
alltrue &= booleanArray[i];
I think this looks ok and behaves well...

This happens because of your application does not allow to append iframe from origin other than your application domain.
If your application have web.config then add the following tag in web.config
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="X-Frame-Options" value="ALLOW" />
</customHeaders>
</httpProtocol>
</system.webServer>
This will allow application to append iframe from other origin also. You can also use the following value for X-Frame-Option
X-FRAME-OPTIONS: ALLOW-FROM https://example.com/
Instead of parsing it manually it's better to use pathinfo function:
$path_parts = pathinfo($value);
$extension = strtolower($path_parts['extension']);
$fileName = $path_parts['filename'];
Best way to close a Swing frame programmatically is to make it behave like it would when the "X" button is pressed. To do that you will need to implement WindowAdapter that suits your needs and set frame's default close operation to do nothing (DO_NOTHING_ON_CLOSE).
Initialize your frame like this:
private WindowAdapter windowAdapter = null;
private void initFrame() {
this.windowAdapter = new WindowAdapter() {
// WINDOW_CLOSING event handler
@Override
public void windowClosing(WindowEvent e) {
super.windowClosing(e);
// You can still stop closing if you want to
int res = JOptionPane.showConfirmDialog(ClosableFrame.this, "Are you sure you want to close?", "Close?", JOptionPane.YES_NO_OPTION);
if ( res == 0 ) {
// dispose method issues the WINDOW_CLOSED event
ClosableFrame.this.dispose();
}
}
// WINDOW_CLOSED event handler
@Override
public void windowClosed(WindowEvent e) {
super.windowClosed(e);
// Close application if you want to with System.exit(0)
// but don't forget to dispose of all resources
// like child frames, threads, ...
// System.exit(0);
}
};
// when you press "X" the WINDOW_CLOSING event is called but that is it
// nothing else happens
this.setDefaultCloseOperation(ClosableFrame.DO_NOTHING_ON_CLOSE);
// don't forget this
this.addWindowListener(this.windowAdapter);
}
You can close the frame programmatically by sending it the WINDOW_CLOSING event, like this:
WindowEvent closingEvent = new WindowEvent(targetFrame, WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(closingEvent);
This will close the frame like the "X" button was pressed.

Till i understand your question,you want to put two conditions to select a row to be deleted.for that,you need to do:
public void deleteEntry(long row,String key_name) {
db.delete(DATABASE_TABLE, KEY_ROWID + "=" + row + " and " + KEY_NAME + "=" + key_name, null);
/*if you just have key_name to select a row,you can ignore passing rowid(here-row) and use:
db.delete(DATABASE_TABLE, KEY_NAME + "=" + key_name, null);

Reading from /dev/random or /dev/urandom character special files is the way to go.
These devices return truly random numbers when read and are designed to help application software choose secure keys for encryption. Such random numbers are extracted from an entropy pool that is contributed by various random events. {LDD3, Jonathan Corbet, Alessandro Rubini, and Greg Kroah-Hartman]
These two files are interface to kernel randomization, in particular
void get_random_bytes_arch(void* buf, int nbytes)
which draws truly random bytes from hardware if such function is by hardware implemented (usually is), or it draws from entropy pool (comprised of timings between events like mouse and keyboard interrupts and other interrupts that are registered with SA_SAMPLE_RANDOM).
dd if=/dev/urandom count=4 bs=1 | od -t d
This works, but writes unneeded output from dd
to stdout. The command below gives just the integer I need. I can even get specified number of random bits as I need by adjustment of the bitmask given to arithmetic expansion:
me@mymachine:~/$ x=$(head -c 1 /dev/urandom > tmp && hexdump
-d tmp | head -n 1 | cut -c13-15) && echo $(( 10#$x & 127 ))
I don't understand how other answers don't answer the original question about how to use PHP (not very consistent with the title).
PHP files or PHP code embedded in HTML code start always with the tag <?php
and ends with ?>
.
You can embed PHP code inside HTML like this (you have to save the file using .php
extension to let PHP server recognize and process it, ie: index.php):
<body>
<?php echo "<div>Hello World!</div>" ?>
</body>
or you can use a whole php file, ie: test.php:
<?php
$mycontent = "Hello World!";
echo "<div>$mycontent</div>";
?> // is not mandatory to put this at the end of the file
there's no document.ready
in PHP, the scripts are processed when they are invoked from the browser or from another PHP file.
It is because you forgot to pass in event
into the click
function:
$('.menuOption').on('click', function (e) { // <-- the "e" for event
e.preventDefault(); // now it'll work
var categories = $(this).attr('rel');
$('.pages').hide();
$(categories).fadeIn();
});
On a side note, e
is more commonly used as opposed to the word event
since Event
is a global variable in most browsers.
const arr= [1, 2, 3]
arr.forEach(function(element){
if(arr[arr.length-1] === element){
console.log("Last Element")
}
})
THis is somthing that should be done in the application layer.
For example, in php it is a s simple as
Edit Added the db connection stuff. No external anything needed.
$sql = "select ...";
$db = new PDO ( "mysql:$dbname", $user, $password) ;
$stmt = $db->prepare($sql);
$stmt->execute();
$result = $stmt->fetchAll();
file_put_contents("output.txt", json_encode($result));
You can use:
public YourClass[] AllProducts()
{
try
{
using (UserDataDataContext db = new UserDataDataContext())
{
return db.mrobProducts.Where(x => x.Status == 1)
.OrderBy(x => x.ID)
.Select(x => new YourClass { ID = x.ID, Name = x.Name, Price = x.Price})
.ToArray();
}
}
catch
{
return null;
}
}
And here is YourClass
implementation:
public class YourClass
{
public string Name {get; set;}
public int ID {get; set;}
public int Price {get; set;}
}
And your AllProducts
method's return type must be YourClass[]
.
import sys
def hello(a, b):
print 'hello and that\'s your sum: {0}'.format(a + b)
if __name__ == '__main__':
hello(int(sys.argv[1]), int(sys.argv[2]))
Moreover see @thibauts answer about how to call python script.
you can do it like that:
<td>
<div style="width: 100%; position: relative; float: left;">inner div</div>
</td>
Please check this example here: Accessing Structure Members
There is explained that the right way to do it is like this:
strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);
An alternative way:
SELECT ...
FROM bla
WHERE finalDate = (SELECT MAX(finalDate) FROM bla) AND
rownum = 1

I have been researching this for a few days, following endless leads that got close, but not quite, to what I was after.
My need is for a simple list of 'symbol, sector, industry'. I'm working in Java and don't want to use any platform native code.
It seems that most other data, like quotes, etc., is readily available.
Finally, followed a suggestion to look at 'finviz.com'. Looks like just the ticket. Try using the following:
http://finviz.com/export.ashx?v=111&t=aapl,cat&o=ticker This comes back as lines, csv style, with a header row, ordered by ticker symbol. You can keep adding tickers. In code, you can read the stream. Or you can let the browser ask you whether to open or save the file.
http://finviz.com/export.ashx?v=111&&o=ticker Same csv style, but pulls all available symbols (a lot, across global exchanges)
Replace 'export' with 'screener' and the data will show up in the browser.
There are many more options you can use, one for every screener element on the site.
So far, this is the most powerful and convenient programmatic way to get the few pieces of data I couldn't otherwise seem to easily get. And, it looks like this site could well be a single source for most of what you might need other than real- or near-real-time quotes.
use Result Rows.
row() method returns a single result row.
$id = $this
-> db
-> select('id')
-> where('email', $email)
-> limit(1)
-> get('users')
-> row();
then, you can simply use as you want. :)
echo "ID is" . $id;
Just had a look at the DOM (document.scripts[1].attributes) of this page that uses google analytics. I can tell you that google is using async="".
[type="text/javascript", async="", src="http://www.google-analytics.com/ga.js"]
There is a mongoose way for doing it.
const itemId = 2;
const query = {
item._id: itemId
};
Person.findOne(query).then(doc => {
item = doc.items.id(itemId );
item["name"] = "new name";
item["value"] = "new value";
doc.save();
//sent respnse to client
}).catch(err => {
console.log('Oh! Dark')
});
You can do this using del
and the /S
flag (to tell it to recurse all files from all subdirectories):
del /S C:\Path\to\directory\*
The RD command can also be used. Recursively delete quietly without a prompt:
@RD /S /Q %VAR_PATH%
ALL YOU HAVE TO DO:
HTML:
<table id="my-table"><tr>
<td> CELL 1 With a lot of text in it</td>
<td> CELL 2 </td>
<td> CELL 3 </td>
<td> CELL 4 With a lot of text in it </td>
<td> CELL 5 </td>
</tr></table>
CSS:
#my-table{width:100%;} /*or whatever width you want*/
#my-table td{width:2000px;} /*something big*/
if you have th
you need to set it too like this:
#my-table th{width:2000px;}
iOS 10
Use app-prefs:
App-prefs:root=MOBILE_DATA_SETTINGS_ID
See gist
You can do this safely (i.e. won't be bugged by files with spaces or \n
in their name) with bash:
$ shopt -s nullglob
$ logfiles=(*.log)
$ echo ${#logfiles[@]}
You need to enable nullglob
so that you don't get the literal *.log
in the $logfiles
array if no files match. (See How to "undo" a 'set -x'? for examples of how to safely reset it.)
If you have only two or three condition(sizes)
then you can use @Overide onMeasure
like
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
And change your size for these conditions in CustomView class easily.

I know this is an old questions but none of the solutions seemed like a good practice hence I am putting how I have solved this issue:
Tried solving this issue by using Homebrew but it was also installing node in /usr/local directory
which would again cause EACCES
error.
Had to use a version manager like nvm for more informations see the official npm guide.
For various operating system.
nvm installs node and it's modules in the user's HOME FOLDER thereby solving EACCES
issues.
A Simple Copy-Paste code snippet:
-(void)LoadLocalHtmlFile:(NSString *)fileName onWebVu:(UIWebView*)webVu
{
[webVu loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:fileName ofType:@"html"]isDirectory:NO]]];
}
Note:
Make sure the html file's Target membership is checked otherwise following exception will get thrown :-
Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:isDirectory:]: nil string parameter'
try importing the below package from random import*
Why fight it? Why not simply control your table width using the bootstrap grid?
<div class="row">
<div class="col-sm-6">
<table></table>
</div>
</div>
This will create a table that is half (6 out of 12) of the width of the containing element.
I sometimes use inline styles as per the other answers, but it is discouraged.
Bootstrap 4 has some nice helper classes for width like w-25
, w-50
, w-75
, w-100
, and w-auto
. This will make the table 50% width:
<table class="w-50"></table>
Here's the doc: https://getbootstrap.com/docs/4.0/utilities/sizing/
you can close it programmatically by calling
$('#form-dialog').dialog('close')
whenever you want.
Here's a short version:
$('#ddlCodes').change(function() {
$('#txtEntry2').text($(this).find(":selected").text());
});
karim79 made a good catch, judging by your element name txtEntry2
may be a textbox, if it's any kind of input, you'll need to use .val()
instead or .text()
like this:
$('#txtEntry2').val($(this).find(":selected").text());
For the "what's wrong?" part of the question: .text()
doesn't take a selector, it takes text you want it set to, or nothing to return the text already there. So you need to fetch the text you want, then put it in the .text(string)
method on the object you want to set, like I have above.
There is a nice gem especially for uploading files : carrierwave. If the wiki does not help , there is a nice RailsCast about the best way to use it . Summarizing , there is a field type file
in Rails forms , which invokes the file upload dialog. You can use it , but the 'magic' is done by carrierwave
gem .
I don't know what do you mean with "how to write to a file" , but I hope this is a nice start.
1. About @Component
@Component functs similarily to @Configuration.
They both indicate that the annotated class has one or more beans need to be registered to Spring-IOC-Container
.
The class annotated by @Component, we call it Component of Spring
. It is a concept that contains several beans.
Component class
needs to be auto-scanned by Spring for registering those beans of the component class
.
2. About @Bean
@Bean is used to annotate the method of component-class
(as mentioned above). It indicate the instance retured by the annotated method needs to be registered to Spring-IOC-Container
.
3. Conclusion
The difference between them two is relatively obivious, they are used in different circumstances
.
The general usage is:
// @Configuration is implemented by @Component
@Configuration
public ComponentClass {
@Bean
public FirstBean FirstBeanMethod() {
return new FirstBean();
}
@Bean
public SecondBean SecondBeanMethod() {
return new SecondBean();
}
}
Implemented using Custom Function. This will check whether the string value can be converted to Decimal safely
CREATE FUNCTION [dbo].[TryParseAsDecimal]
(
@Value NVARCHAR(4000)
,@Precision INT
,@Scale INT
)
RETURNS BIT
AS
BEGIN
IF(ISNUMERIC(@Value) =0) BEGIN
RETURN CAST(0 AS BIT)
END
SELECT @Value = REPLACE(@Value,',','') --Removes the comma
--This function validates only the first part eg '1234567.8901111111'
--It validates only the values before the '.' ie '1234567.'
DECLARE @Index INT
DECLARE @Part1Length INT
DECLARE @Part1 VARCHAR(4000)
SELECT @Index = CHARINDEX('.', @Value, 0)
IF (@Index>0) BEGIN
--If decimal places, extract the left part only and cast it to avoid leading zeros (eg.'0000000001' => '1')
SELECT @Part1 =LEFT(@Value, @Index-1);
SELECT @Part1=SUBSTRING(@Part1, PATINDEX('%[^0]%', @Part1+'.'), LEN(@Part1));
SELECT @Part1Length = LEN(@Part1);
END
ELSE BEGIN
SELECT @Part1 =CAST(@Value AS DECIMAL);
SELECT @Part1Length= LEN(@Part1)
END
IF (@Part1Length > (@Precision-@Scale)) BEGIN
RETURN CAST(0 AS BIT)
END
RETURN CAST(1 AS BIT)
END
