I would write this in Notepad or WordPad for a basic logoff command:
@echo off
shutdown -l
This is basically the same as clicking start and logoff manually, but it is just slightly faster if you have the batch file ready.

public override void Execute(CoroutineExecutionContext context)
{
Application.Current.Shutdown();
base.Execute(context);
}
}

OnCompleted(this, new ResultCompletionEventArgs { WasCancelled = true });
}
}
Take a look at the Event Log API. Case a) (bluescreen, user cut the power cord or system hang) causes a note ('system did not shutdown correctly' or something like that) to be left in the 'System' event log the next time the system is rebooted properly. You should be able to access it programmatically using the above API (honestly, I've never used it but it should work).
<service android:name=".Service2"
android:process="@string/app_name"
android:exported="true"
android:isolatedProcess="true"
/>
Declare this in your manifest. Give a custom name to your process and make that process isolated and exported .
There is no .net native method for shutting off the computer. You need to P/Invoke the ExitWindows or ExitWindowsEx API call.
I found this topic while searching for run script for startup and shutdown Windows 10. Those answers above didn't working. For me on windows 10 worked when I put scripts to task scheduler. How to do this: press window key and write Task scheduler, open it, then on the right is Add task... button. Here you can add scripts. PS: I found action for startup and logout user, there is not for shutdown.

net stop MySQL
To Start MySQL Service
net start MySQL.

# service mysqld start
# service mysqld stop
# service mysqld restart
I know this answer is late but i hope it helps for some one.
You're obviously not closing your file descriptors before opening new ones. Are you on windows or linux?
wmic bios get serialnumber
if run from a command line (start-run should also do the trick) prints out on screen the Serial Number of the product,
(for example in a toshiba laptop it would print out the serial number of the laptop.
with this serial number you can then identify your laptop model if you need ,from the makers service website-usually..:):)

Specify "required" keyword in one of the select statements. If you want to change the default way of its appearance. You can follow these steps. This is just for extra info if you have any intention to modify the default behavior.
Add the following into you .css
file.
/* style all elements with a required attribute */
:required {
background: red;
}
For more information you can refer following URL.
JSONArray jsonChildArray = (JSONArray) jsonChildArray.get("LanguageLevels");
JSONObject secObject = (JSONObject) jsonChildArray.get(1);
I think this should work, but i do not have the possibility to test it at the moment..
If you have a more complicated use case than described in the answer of Glennie Helles Sindholt e.g. you have other/few non-join column names that are also same and want to distinguish them while selecting it's best to use aliasses, e.g:
df3 = df1.select("a", "b").alias("left")\
.join(df2.select("a", "b").alias("right"), ["a"])\
.select("left.a", "left.b", "right.b")
df3.columns
['a', 'b', 'b']

This is a known bug on the initial 2.5.1, and has been fixed in early 2007 (Redhat 2.5.1-5) according to the bug reports. Unfortunately Apple is still using 2.5.1 even on Mac OS X 10.7.2.
You could get a newer version via Homebrew (3.0) or MacPorts (2.26) or fink (3.0-1).
Edit: Apparently it has been fixed on OS X 10.11 (or maybe earlier), even though the grep version reported is still 2.5.1.

I was looking into this issue a bit for my own purposes; I had a slice of structs (including some pointers) and I wanted to make sure I got it right; ended up on this thread, and wanted to share my results.
To practice, I did a little go playground: https://play.golang.org/p/9i4gPx3lnY
which evals to this:
package main
import "fmt"
type Blah struct {
babyKitten int
kittenSays *string
}
func main() {
meow := "meow"
Blahs := []Blah{}
fmt.Printf("Blahs: %v\n", Blahs)
Blahs = append(Blahs, Blah{1, &meow})
fmt.Printf("Blahs: %v\n", Blahs)
Blahs = append(Blahs, Blah{2, &meow})
fmt.Printf("Blahs: %v\n", Blahs)
//fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
Blahs = nil
meow2 := "nyan"
fmt.Printf("Blahs: %v\n", Blahs)
Blahs = append(Blahs, Blah{1, &meow2})
fmt.Printf("Blahs: %v\n", Blahs)
fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
}
Running that code as-is will show the same memory address for both "meow" and "meow2" variables as being the same:
Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
Blahs: []
Blahs: [{1 0x1030e0f0}]
kittenSays: nyan
which I think confirms that the struct is garbage collected. Oddly enough, uncommenting the commented print line, will yield different memory addresses for the meows:
Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
kittenSays: meow
Blahs: []
Blahs: [{1 0x1030e0f8}]
kittenSays: nyan
I think this may be due to the print being deferred in some way (?), but interesting illustration of some memory mgmt behavior, and one more vote for:
[]MyStruct = nil

It is the severity level of the error
. The levels are from 11 - 20 which throw an error in SQL
. The higher the level, the more severe the level and the transaction
should be aborted.
You will get the syntax error when you do:
RAISERROR('Cannot Insert where salary > 1000').
Because you have not specified the correct parameters
(severity level
or state
).
If you wish to issue a warning and not an exception
, use levels 0 - 10.
From MSDN:
severity
Is the user-defined severity level associated with this message. When using msg_id to raise a user-defined message created using sp_addmessage, the severity specified on RAISERROR overrides the severity specified in sp_addmessage. Severity levels from 0 through 18 can be specified by any user. Severity levels from 19 through 25 can only be specified by members of the sysadmin fixed server role or users with ALTER TRACE permissions. For severity levels from 19 through 25, the WITH LOG option is required.
state
Is an integer from 0 through 255. Negative values or values larger than 255 generate an error. If the same user-defined error is raised at multiple locations, using a unique state number for each location can help find which section of code is raising the errors. For detailed description here
The simplest answer would be
--Setup a test table called "t1"
create table t1
(date datetime,
value int)
-- Load the data. -- Note: date format different than in the question
insert into t1
Select '5/18/2010 13:00',40
union all
Select '5/18/2010 14:00',20
union all
Select '5/18/2010 15:00',60
union all
Select '5/18/2010 16:00',30
union all
Select '5/18/2010 17:00',60
union all
Select '5/18/2010 18:00',25
-- find the row with the max qty and min date.
select *
from t1
where value =
(select max(value) from t1)
and date =
(select min(date)
from t1
where value = (select max(value) from t1))
I know you can do the "TOP 1" answer, but usually your solution gets just complicated enough that you can't use that for some reason.
After studying some jQuery at Codeacademy I found a solution to bind a key with the animate property. The whole idea was to animate without scrolling to jump from one section to another. The example from Codeacademy was to move Mario through the DOM but I applied this for my website sections (CSS with 100% height). Here is a part of the code:
$(document).keydown(function(key) {
switch(parseInt(key.which, 10)) {
case 39:
$('section').animate({top: "-=100%"}, 2000);
break;
case 37:
$('section').animate({top: "+=100%"}, 2000);
break;
default:
break;
}
});
I think you could use this for any letter and property.

(list.Count() + 9) / 10
Everything else here is either overkill or simply wrong (except for bestsss' answer, which is awesome). We do not want the overhead of a function call (Math.Truncate()
, Math.Ceiling()
, etc.) when simple math is enough.
OP's question generalizes (pigeonhole principle) to:
How many boxes do I need to store
x
objects if onlyy
objects fit into each box?
The solution:
(x + y - 1) ÷ y
using integer division.You'll recall from 3rd grade math that integer division is what we're doing when we say 5 ÷ 2 = 2
.
Floating-point division is when we say 5 ÷ 2 = 2.5
, but we don't want that here.
Many programming languages support integer division. In languages derived from C, you get it automatically when you divide int
types (short
, int
, long
, etc.). The remainder/fractional part of any division operation is simply dropped, thus:
5 / 2 == 2
Replacing our original question with x = 5
and y = 2
we have:
How many boxes do I need to store 5 objects if only 2 objects fit into each box?
The answer should now be obvious: 3 boxes
-- the first two boxes hold two objects each and the last box holds one.
(x + y - 1) ÷ y =
(5 + 2 - 1) ÷ 2 =
6 ÷ 2 =
3
So for the original question, x = list.Count()
, y = 10
, which gives the solution using no additional function calls:
(list.Count() + 9) / 10
Are you passing the DISPLAY parameter to your Jenkins job?
I assume you are trying to execute the tests in headless mode, too. So setup some x service (i.e. Xvfb) and pass the DISPLAY number to your job. Worked for me.
You can hide an image using javascript like this:
document.images['imageName'].style.visibility = hidden;
If that isn't what you are after, you need to explain yourself more clearly.
Every response here is using vImageBoxConvolve_ARGB8888 this function is really, really slow, that is fine, if the performance is not a high priority requirement, but if you are using this for transitioning between two View Controllers (for example) this approach means times over 1 second or maybe more, that is very bad to the user experience of your application.
If you prefer leave all this image processing to the GPU (And you should) you can get a much better effect and also awesome times rounding 50ms (supposing that you have a time of 1 second in the first approach), so, lets do it.
First download the GPUImage Framework (BSD Licensed) here.
Next, Add the following classes (.m and .h) from the GPUImage (I'm not sure that these are the minimum needed for the blur effect only)
GPUImageTwoPassTextureSamplingFilter
iOS/GPUImage-Prefix.pch
Next, create a category on UIImage, that will add a blur effect to an existing UIImage:
#import "UIImage+Utils.h"
#import "GPUImagePicture.h"
#import "GPUImageSolidColorGenerator.h"
#import "GPUImageAlphaBlendFilter.h"
#import "GPUImageBoxBlurFilter.h"
@implementation UIImage (Utils)
- (UIImage*) GPUBlurredImage
{
GPUImagePicture *source =[[GPUImagePicture alloc] initWithImage:self];
CGSize size = CGSizeMake(self.size.width * self.scale, self.size.height * self.scale);
GPUImageBoxBlurFilter *blur = [[GPUImageBoxBlurFilter alloc] init];
[blur setBlurRadiusInPixels:4.0f];
[blur setBlurPasses:2.0f];
[blur forceProcessingAtSize:size];
[source addTarget:blur];
GPUImageSolidColorGenerator * white = [[GPUImageSolidColorGenerator alloc] init];
[white setColorRed:1.0f green:1.0f blue:1.0f alpha:0.1f];
[white forceProcessingAtSize:size];
GPUImageAlphaBlendFilter * blend = [[GPUImageAlphaBlendFilter alloc] init];
blend.mix = 0.9f;
[blur addTarget:blend];
[white addTarget:blend];
[blend forceProcessingAtSize:size];
[source processImage];
return [blend imageFromCurrentlyProcessedOutput];
}
@end
And last, add the following frameworks to your project:
AVFoundation CoreMedia CoreVideo OpenGLES
Yeah, got fun with this much faster approach ;)

The mouse's position is reported on the event
object received by a handler for the mousemove
event, which you can attach to the window (the event bubbles):
(function() {
document.onmousemove = handleMouseMove;
function handleMouseMove(event) {
var eventDoc, doc, body;
event = event || window.event; // IE-ism
// If pageX/Y aren't available and clientX/Y are,
// calculate pageX/Y - logic taken from jQuery.
// (This is to support old IE)
if (event.pageX == null && event.clientX != null) {
eventDoc = (event.target && event.target.ownerDocument) || document;
doc = eventDoc.documentElement;
body = eventDoc.body;
event.pageX = event.clientX +
(doc && doc.scrollLeft || body && body.scrollLeft || 0) -
(doc && doc.clientLeft || body && body.clientLeft || 0);
event.pageY = event.clientY +
(doc && doc.scrollTop || body && body.scrollTop || 0) -
(doc && doc.clientTop || body && body.clientTop || 0 );
}
// Use event.pageX / event.pageY here
}
})();
(Note that the body of that if
will only run on old IE.)
Example of the above in action - it draws dots as you drag your mouse over the page. (Tested on IE8, IE11, Firefox 30, Chrome 38.)
If you really need a timer-based solution, you combine this with some state variables:
(function() {
var mousePos;
document.onmousemove = handleMouseMove;
setInterval(getMousePosition, 100); // setInterval repeats every X ms
function handleMouseMove(event) {
var dot, eventDoc, doc, body, pageX, pageY;
event = event || window.event; // IE-ism
// If pageX/Y aren't available and clientX/Y are,
// calculate pageX/Y - logic taken from jQuery.
// (This is to support old IE)
if (event.pageX == null && event.clientX != null) {
eventDoc = (event.target && event.target.ownerDocument) || document;
doc = eventDoc.documentElement;
body = eventDoc.body;
event.pageX = event.clientX +
(doc && doc.scrollLeft || body && body.scrollLeft || 0) -
(doc && doc.clientLeft || body && body.clientLeft || 0);
event.pageY = event.clientY +
(doc && doc.scrollTop || body && body.scrollTop || 0) -
(doc && doc.clientTop || body && body.clientTop || 0 );
}
mousePos = {
x: event.pageX,
y: event.pageY
};
}
function getMousePosition() {
var pos = mousePos;
if (!pos) {
// We haven't seen any movement yet
}
else {
// Use pos.x and pos.y
}
}
})();
As far as I'm aware, you can't get the mouse position without having seen an event, something which this answer to another Stack Overflow question seems to confirm.
Side note: If you're going to do something every 100ms (10 times/second), try to keep the actual processing you do in that function very, very limited. That's a lot of work for the browser, particularly older Microsoft ones. Yes, on modern computers it doesn't seem like much, but there is a lot going on in browsers... So for example, you might keep track of the last position you processed and bail from the handler immediately if the position hasn't changed.
On Debian 9 I had to:
$ sudo update-ca-certificates --fresh
$ export SSL_CERT_DIR=/etc/ssl/certs
I'm not sure why, but this enviroment variable was never set.
Try this solution use NavUtils.navigateUpFromSameTask(this); in the child activity: https://stackoverflow.com/a/49980835/7308789
$http is a promise too, you can make it simpler:
return $q.all(tasks.map(function(d){
return $http.post('upload/tasks',d).then(someProcessCallback, onErrorCallback);
}));
Pandas
uses matplotlib
as a library for basic plots. The easiest way in your case will using the following:
import pandas as pd
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
df.plot(x='col_name_1', y='col_name_2', style='o')
However, I would recommend to use seaborn
as an alternative solution if you want have more customized plots while not going into the basic level of matplotlib.
In this case you the solution will be following:
import pandas as pd
import seaborn as sns
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df)
I had one long table td cell, this forced the table to the edges of the browser and looked ugly. I just wanted that column to be fixed size only and break the words when it reaches the specified width. So this worked well for me:
<td><div style='width: 150px;'>Text to break here</div></td>
You don't need to specify any kind of style to table, tr elements. You may also use overflow:hidden; as suggested by other answers but it causes for the excess text to disappear.
This should solve your problem:
td {
/* <http://www.w3.org/wiki/CSS/Properties/text-align>
* left, right, center, justify, inherit
*/
text-align: center;
/* <http://www.w3.org/wiki/CSS/Properties/vertical-align>
* baseline, sub, super, top, text-top, middle,
* bottom, text-bottom, length, or a value in percentage
*/
vertical-align: top;
}
mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).
I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

The Python way - it is easier to receive forgiveness than ask permission!
If you don't use ngRoute module, i.e. you don't have $viewContentLoaded event.
You can use another directive method:
angular.module('someModule')
.directive('someDirective', someDirective);
someDirective.$inject = ['$rootScope', '$timeout']; //Inject services
function someDirective($rootScope, $timeout){
return {
restrict: "A",
priority: Number.MIN_SAFE_INTEGER, //Lowest priority
link : function(scope, element, attr){
$timeout(
function(){
$rootScope.$emit("Some:event");
}
);
}
};
}
Accordingly to trusktr's answer it has lowest priority. Plus $timeout will cause Angular to run through an entire event loop before callback execution.
$rootScope used, because it allow to place directive in any scope of the application and notify only necessary listeners.
$rootScope.$emit will fire an event for all $rootScope.$on listeners only. The interesting part is that $rootScope.$broadcast will notify all $rootScope.$on as well as $scope.$on listeners Source
A dict (really, a defaultdict) gives you a pretty easy way to do this trick:
from collections import defaultdict
bool_mapping = defaultdict(bool) # Will give you False for non-found values
for val in ['True', 'yes', ...]:
bool_mapping[val] = True
print(bool_mapping['True']) # True
print(bool_mapping['kitten']) # False
It's really easy to tailor this method to the exact conversion behavior you want -- you can fill it with allowed Truthy and Falsy values and let it raise an exception (or return None) when a value isn't found, or default to True, or default to False, or whatever you want.

I had a similar requirement to this but my replace var contained an ampersand. Escaping the ampersand like this solved my problem:
replace="salt & pepper"
echo "pass the salt" | sed "s/salt/${replace/&/\&}/g"
There are many ways to convert an int to ASCII (depending on your needs) but here is a way to convert each integer byte to an ASCII character:
private static String toASCII(int value) {
int length = 4;
StringBuilder builder = new StringBuilder(length);
for (int i = length - 1; i >= 0; i--) {
builder.append((char) ((value >> (8 * i)) & 0xFF));
}
return builder.toString();
}
For example, the ASCII text for "TEST" can be represented as the byte array:
byte[] test = new byte[] { (byte) 0x54, (byte) 0x45, (byte) 0x53, (byte) 0x54 };
Then you could do the following:
int value = ByteBuffer.wrap(test).getInt(); // 1413829460
System.out.println(toASCII(value)); // outputs "TEST"
...so this essentially converts the 4 bytes in a 32-bit integer to 4 separate ASCII characters (one character per byte).
yourSelect.setAttribute( "onchange", "yourFunction()" );
I had a similar goal - and came to this solution:
select *
from jobdetails as JD
where not exists ( select code from table_of_codes as TC
where JD.job_no like TC.code )
I'm assuming that your various codes ('0711%', '0712%', etc), including the %, are stored in a table, which I'm calling *table_of_codes*, with field code.
If the % is not stored in the table of codes, just concatenate the '%'. For example:
select *
from jobdetails as JD
where not exists ( select code from table_of_codes as TC
where JD.job_no like concat(TC.code, '%') )
The concat() function may vary depending on the particular database, as far as I know.
I hope that it helps. I adapted it from:

If you want to rotate a vector you should construct what is known as a rotation matrix.
Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are
x' = x cos ? - y sin ?
y' = x sin ? + y cos ?
To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider
Unit vector along X axis = <1, 0>
x' = 1 cos 90 - 0 sin 90 = 0
y' = 1 sin 90 + 0 cos 90 = 1
New coordinates of the vector, <x', y'> = <0, 1> ? Y-axis
When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is
|cos ? -sin ?| |x| = |x cos ? - y sin ?| = |x'|
|sin ? cos ?| |y| |x sin ? + y cos ?| |y'|
That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be
|cos ? -sin ? 0| |x| |x cos ? - y sin ?| |x'|
|sin ? cos ? 0| |y| = |x sin ? + y cos ?| = |y'|
| 0 0 1| |z| | z | |z'|
around the Y-axis would be
| cos ? 0 sin ?| |x| | x cos ? + z sin ?| |x'|
| 0 1 0| |y| = | y | = |y'|
|-sin ? 0 cos ?| |z| |-x sin ? + z cos ?| |z'|
around the X-axis would be
|1 0 0| |x| | x | |x'|
|0 cos ? -sin ?| |y| = |y cos ? - z sin ?| = |y'|
|0 sin ? cos ?| |z| |y sin ? + z cos ?| |z'|
Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.
Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.
I hope this clarifies basic rotation.
The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.
I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).
A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.
DT[order(-x)]
works as expected. I have data.table version 1.9.4. Maybe this was fixed in a recent version.
Also, I suggest the setorder(DT, -x)
syntax in keeping with the set* commands like setnames
, setkey
Seems like last_accessed_on, is a date time, and you are converting '23-07-2014 09:37:00' to a varchar. This would not work, and give you conversion errors. Try
last_accessed_on= convert(datetime,'23-07-2014 09:37:00', 103)
I think you can avoid the cast though, and update with '23-07-2014 09:37:00'. It should work given that the format is correct.
Your query is not going to work because in last_accessed_on (which is DateTime2 type), you are trying to pass a Varchar value.
You query would be
UPDATE student_queues SET Deleted=0 , last_accessed_by='raja', last_accessed_on=convert(datetime,'23-07-2014 09:37:00', 103)
WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'
In your example you should mock Listener item and use Mockito.verify to check interactions with it

Some where able to get an updated favicon by adding an URL parameter: ?v=1
after the link href which changes the resource link and therefore loads the favicon without cache (thanks @Stanislav).
<link rel="icon" type="image/x-icon" href="favicon.ico?v=2" />
How did you import the favicon? How you should add it.
Normal favicon:
<link rel="icon" href="favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />
PNG/GIF favicon:
<link rel="icon" type="image/gif" href="favicon.gif" />
<link rel="icon" type="image/png" href="favicon.png" />
in the <head>
Tag.
Another thing could be the problem that chrome can't display favicons, if it's local (not uploaded to a webserver). Only if the file/icon would be in the downloads directory chrome is allowed to load this data - more information about this can be found here: local (file://) website favicon works in Firefox, not in Chrome or Safari- why?
Try to rename it from favicon.{whatever}
to {yourfaviconname}.{whatever}
but I would suggest you to still have the normal favicon. This has solved my issue on IE.
Found another solution for this which works great! I simply added my favicon as Base64 Encoded Image directly inside the tag like this:

I'm not exactly sure where my problem was, but I believe it was because I was using the same global packages from both npm and Yarn.
I uninstalled all the npm global packages, then when using yarn commands once again, the problem was gone.
To see global packages installed...
for npm:
npm ls -g --depth=0
for Yarn:
yarn global list
I then uninstalled each package I saw in the npm listing, using:
npm uninstall -g <package-name>
I had similar problems for one of my projects to create a URI object from a string. I couldn't find any clean solution either. Here's what I came up with :
public static URI encodeURL(String url) throws MalformedURLException, URISyntaxException
{
URI uriFormatted = null;
URL urlLink = new URL(url);
uriFormatted = new URI("http", urlLink.getHost(), urlLink.getPath(), urlLink.getQuery(), urlLink.getRef());
return uriFormatted;
}
You can use the following URI constructor instead to specify a port if needed:
URI uri = new URI(scheme, userInfo, host, port, path, query, fragment);
For Windows 7 x86 you can also download the ISO: http://www.microsoft.com/en-us/download/confirmation.aspx?id=8442
And run \Setup\WinSDKDebuggingTools\dbg_x86.msi
WinDbg.exe will then be installed (default location) to: C:\Program Files (x86)\Debugging Tools for Windows (x86)
It will work.
long yourmilliseconds = System.currentTimeMillis();
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd,yyyy HH:mm");
Date resultdate = new Date(yourmilliseconds);
System.out.println(sdf.format(resultdate));
I use the free file searching program Everything, search for *.sql files across my C: drive, and then sort by Last Modified, and then browse by the date I think it was probably last executed.
It usually brings up loads of autorecovery files from a variety of locations. And you don't have to worry where the latest version of SSMS/VS is saving the backup files this version.
You need to create a separate interface for your custom methods:
public interface AccountRepository
extends JpaRepository<Account, Long>, AccountRepositoryCustom { ... }
public interface AccountRepositoryCustom {
public void customMethod();
}
and provide an implementation class for that interface:
public class AccountRepositoryImpl implements AccountRepositoryCustom {
@Autowired
@Lazy
AccountRepository accountRepository; /* Optional - if you need it */
public void customMethod() { ... }
}

Note that the naming scheme has changed between versions. See https://stackoverflow.com/a/52624752/66686 for details.
All hover is doing behind the scenes is binding to the mouseover and mouseout property. I would bind and unbind your functions from those events individually.
For example, say you have the following html:
<a href="#" class="myLink">Link</a>
then your jQuery would be:
$(document).ready(function() {
function mouseOver()
{
$(this).css('color', 'red');
}
function mouseOut()
{
$(this).css('color', 'blue');
}
// either of these might work
$('.myLink').hover(mouseOver, mouseOut);
$('.myLink').mouseover(mouseOver).mouseout(mouseOut);
// otherwise use this
$('.myLink').bind('mouseover', mouseOver).bind('mouseout', mouseOut);
// then to unbind
$('.myLink').click(function(e) {
e.preventDefault();
$('.myLink').unbind('mouseover', mouseOver).unbind('mouseout', mouseOut);
});
});
Here's a solution for those that may still be struggling. You want to add a mouseover
event on the 'parent' element of the child element(s) you want detected. The below code shows you how to go about it.
const wrapper = document.getElementById('wrapper') //parent element
const position = document.getElementById("displaySelection")
wrapper.addEventListener('mousemove', function(e) {
let elementPointed = document.elementFromPoint(e.clientX, e.clientY)
console.log(elementPointed)
});
To add to the valuable content, I would like to create this reminder on why sometimes RegEx within VBA is not ideal. Not all expressions are supported, but instead may throw an Error 5017
and may leave the author guessing (which I am a victim of myself).
Whilst we can find some sources on what is supported, it would be helpfull to know which metacharacters etc. are not supported. A more in-depth explaination can be found here. Mentioned in this source:
"Although "VBScript’s regular expression ... version 5.5 implements quite a few essential regex features that were missing in previous versions of VBScript. ... JavaScript and VBScript implement Perl-style regular expressions. However, they lack quite a number of advanced features available in Perl and other modern regular expression flavors:"
So, not supported are:
\A
, alternatively use the ^
caret to match postion before 1st char in string\Z
, alternatively use the $
dollar sign to match postion after last char in string(?<=a)b
(whilst postive LookAhead is supported)(?<!a)b
(whilst negative LookAhead is supported)\{uFFFF}
/i
(case sensitivity) or /g
(global) etc. Set these through the RegExp
object properties > RegExp.Global = True
and RegExp.IgnoreCase = True
if available.'
comments in script I already hit a wall more than once using regular expressions within VBA. Usually with LookBehind
but sometimes I even forget the modifiers. I have not experienced all these above mentioned backdrops myself but thought I would try to be extensive referring to some more in-depth information. Feel free to comment/correct/add. Big shout out to regular-expressions.info for a wealth of information.
P.S. You have mentioned regular VBA methods and functions, and I can confirm they (at least to myself) have been helpful in their own ways where RegEx would fail.
For preloading background images set with CSS, the most efficient answer i came up with was a modified version of some code I found that did not work:
$(':hidden').each(function() {
var backgroundImage = $(this).css("background-image");
if (backgroundImage != 'none') {
tempImage = new Image();
tempImage.src = backgroundImage;
}
});
The massive benefit of this is that you don't need to update it when you bring in new background images in the future, it will find the new ones and preload them!
Use :
getline(cin, input);
the function can be found in
#include <string>

When trying to make changes to a Pandas dataframe using a function, we use 'inplace=True' if we want to commit the changes to the dataframe. Therefore, the first line in the following code changes the name of the first column in 'df' to 'Grades'. We need to call the database if we want to see the resulting database.
df.rename(columns={0: 'Grades'}, inplace=True)
df
We use 'inplace=False' (this is also the default value) when we don't want to commit the changes but just print the resulting database. So, in effect a copy of the original database with the committed changes is printed without altering the original database.
Just to be more clear, the following codes do the same thing:
#Code 1
df.rename(columns={0: 'Grades'}, inplace=True)
#Code 2
df=df.rename(columns={0: 'Grades'}, inplace=False}
With serialize the data as JSON and Base64, dependency jquery.cookie.js :

}
var getCookieObj = function (key) {
var cookie = $.cookie(key);
if (typeof cookie === "undefined") return null;
return JSON.parse(atob(cookie));
}

Just as Matt says, use Process.Start.
You can pass a URL, or a document. They will be started by the registered application.
Example:
Process.Start("Test.Txt");
This will start Notepad.exe with Text.Txt loaded.

Solved:
At the end of the file /etc/security/limits.conf
you need to add the following lines:
* soft nofile 16384
* hard nofile 16384
In the current console from root (sudo does not work) to do:
ulimit -n 16384
Although this is optional, if it is possible to restart the server.
In /etc/nginx/nginx.conf
file to register the new value worker_connections
equal to 16384
divide by value worker_processes
.
If not did ulimit -n 16384
, need to reboot, then the problem will recede.
PS:
If after the repair is visible in the logs error accept() failed (24: Too many open files)
:
In the nginx configuration, propevia (for example):
worker_processes 2;
worker_rlimit_nofile 16384;
events {
worker_connections 8192;
}
In addition to the other answers.
If you control the structure of the DataTable there is a shortcut for adding rows:
// Assume you have a data table defined as in your example named dt dt.Rows.Add("Name", "Marks");
The DataRowCollection.Add() method has an overload that takes a param array of objects. This method lets you pass as many values as needed, but they must be in the same order as the columns are defined in the table.
So while this is a convenient way to add row data, it can be risky to use. If the table structure changes your code will fail.
The objdump
tool can tell you this information. If you invoke objdump
with the -x
option, to get it to output all headers then you'll find the shared object dependencies right at the start in the "Dynamic Section".

on my system gives the following information in the "Dynamic Section":

The direct shared object dependencies are listing as 'NEEDED' values. So in the example above, libXpm.so.4
on my system just needs libX11.so.6
and libc.so.6
.
It's important to note that this doesn't mean that all the symbols needed by the binary being passed to objdump
will be present in the libraries, but it does at least show what libraries the loader will try to load when loading the binary.
This may or not help someone, but it might be a quick reference. This is also similar to all the answers presented above.
I have a lot of locations that generate list using the structure below:
return (
{myList.map(item => (
<>
<div class="some class">
{item.someProperty}
....
</div>
</>
)}
)
After a little trial and error (and some frustrations), adding a key property to the outermost block resolved it. Also, note that the <>
tag is now replaced with the <div>
tag now.
return (
{myList.map((item, index) => (
<div key={index}>
<div class="some class">
{item.someProperty}
....
</div>
</div>
)}
)
Of course, I've been naively using the iterating index (index) to populate the key value in the above example. Ideally, you'd use something which is unique to the list item.
Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.
from numpy.polynomial import Polynomial
p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())
p
uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with
pnormal = p.convert(domain=(-1, 1))
I guess you're talking about C#. If so, you can try this
ArrayList CompareArrayList(ArrayList a, ArrayList b)
{
ArrayList output = new ArrayList();
for (int i = 0; i < a.Count; i++)
{
string str = (string)a[i];
if (!b.Contains(str))
{
if(!output.Contains(str)) // check for dupes
output.Add(str);
}
}
return output;
}
If anyone comes here after me, this is the answer that worked for me.
NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)

On my AWS beanstalk server, I don't see $_SERVER['HTTPS'] variable. I do see $_SERVER['HTTP_X_FORWARDED_PROTO'] which can be either 'http' or 'https' so if you're hosting on AWS, use this:
if ($_SERVER['HTTP_HOST'] != 'localhost' and $_SERVER['HTTP_X_FORWARDED_PROTO'] != "https") {
$location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $location);
exit;
}
You have at least two issues in your code:
ng-change="getScoreData(Score)
Angular doesn't see getScoreData
method that refers to defined service
getScoreData: function (Score, callback)
We don't need to use callback since GET
returns promise. Use then
instead.
Here is a working example (I used random address only for simulation):
HTML
<select ng-model="score"
ng-change="getScoreData(score)"
ng-options="score as score.name for score in scores"></select>
<pre>{{ScoreData|json}}</pre>
JS
var fessmodule = angular.module('myModule', ['ngResource']);
fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {
$scope.scores = [{
name: 'Bukit Batok Street 1',
URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
}, {
name: 'London 8',
URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
}];
$scope.getScoreData = function(score) {
ScoreDataService.getScoreData(score).then(function(result) {
$scope.ScoreData = result;
}, function(result) {
alert("Error: No data returned");
});
};
});
fessmodule.$inject = ['$scope', 'ScoreDataService'];
fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {
var factory = {
getScoreData: function(score) {
console.log(score);
var data = $http({
method: 'GET',
url: score.URL
});
return data;
}
}
return factory;
}]);

You can get this exception at many different places in the MVC framework (e.g. it can't create the controller, or it can't create a model to give that controller).
The only easy way I've found to diagnose this problem is to override MVC as close to the exception as possible with your own code. Then your code will break inside Visual Studio when this exception occurs, and you can read the Type causing the problem from the stack trace.
This seems like a horrible way to approach this problem, but it's very fast, and very consistent.
For example, if this error is occurring inside the MVC DefaultModelBinder (which you will know by checking the stack trace), then replace the DefaultModelBinder with this code:
public class MyDefaultModelBinder : System.Web.Mvc.DefaultModelBinder
{
protected override object CreateModel(System.Web.Mvc.ControllerContext controllerContext, System.Web.Mvc.ModelBindingContext bindingContext, Type modelType)
{
return base.CreateModel(controllerContext, bindingContext, modelType);
}
}
And update your Global.asax.cs:
public class MvcApplication : System.Web.HttpApplication
{
...
protected void Application_Start(object sender, EventArgs e)
{
ModelBinders.Binders.DefaultBinder = new MyDefaultModelBinder();
}
}
Now the next time you get that exception, Visual Studio will stop inside your MyDefaultModelBinder class, and you can check the "modelType" property to see what type caused the problem.
The example above works for when you get the "No parameterless constructor defined for this object" exception during model binding, only. But similar code can be written for other extension points in MVC (e.g. controller construction).
You're going to want the second field after the colon, not the first.
grep -n "text to find" file.txt | cut -f2 -d:

Perhaps if you'd use ??
operator when assigning your string variable, it might help you.
string str = SomeMethodThatReturnsaString() ?? "";
// if SomeMethodThatReturnsaString() returns a null value, "" is assigned to str.
This is an old question, but the current answers are incorrect :)
Use yum whatprovides, with the absolute path to the file you want (which may be wildcarded). For example:
yum whatprovides '*bin/grep'
Returns
grep-2.5.1-55.el5.x86_64 : The GNU versions of grep pattern matching utilities.
Repo : base
Matched from:
Filename : /bin/grep
You may prefer the output and speed of the repoquery
tool, available in the yum-utils
package.
sudo yum install yum-utils
repoquery --whatprovides '*bin/grep'
grep-0:2.5.1-55.el5.x86_64
grep-0:2.5.1-55.el5.x86_64
repoquery
can do other queries such as listing package contents, dependencies, reverse-dependencies, etc.
At work we have a common library that is used by a few different projects all in a single repository. Originally we used the published (private) version (npm install --save rp-utils) but that lead to a lot of needless version updates as we developed. The library lives in a sister directory to the applications and we are able to use a relative path instead of a version. Instead of "rp-utils": "^1.3.34" in package.json it now is:
{
"dependencies": { ...
"rp-utils": "../rp-utils",
...
the rp-utils directory contains a publishable npm package

Something none of the other answers touch on is that your first loop is indexing though the list. Whereas the for-each loop is using an Iterator
. Some lists like LinkedList
will iterate faster with an Iterator
versus get(i)
. This is because because link list's iterator keeps track of the current pointer. Whereas each get
in your for i=0 to 9 has to recompute the offset into the linked list. In general, its better to use for-each or an Iterator
because it will be using Collection
s iterator, which in theory is optimized for the collection type.

It's a prefix to indicate the number is in hexadecimal rather than in some other base. The C programming language uses it to tell compiler.
Example :
0x6400
translates to 6*16^3 + 4*16^2 + 0*16^1 +0*16^0 = 25600.
When compiler reads 0x6400
, It understands the number is hexadecimal with the help of 0x term. Usually we can understand by (6400)16 or (6400)8
or any base ..
Hope Helped in some way.

By default android will set Holo to the Dark theme. There is no theme called Holo.Dark, there's only Holo.Light, that's why you are getting the resource not found error.
So just set it to:

The NuGet documentation provides instructions on how to accomplish this and I just followed them successfully for Visual Studio 2015 & Visual Studio 2017 against VSTS (Azure-hosted TFS). Everything is fully updated as of Nov 2016 Aug 2018.
I recommend you follow NuGet's instructions but just to recap what I did:
packages
folder is not committed to TFS. If it is, get it out of there..sln
file exists in unless otherwise specified (NuGet's instructions aren't completely clear on this)..nuget
folder. You can use Windows Explorer to name it .nuget.
for it to successfully save as .nuget
(it automatically removes the last period) but directly trying to name it .nuget
may not work (you may get an error or it may change the name, depending on your version of Windows).
Or name the directory nuget, and open the parent directory in command line prompt. type. ren nuget .nugetNuGet.config
file and add the following contents and save it:NuGet.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<solution>
<add key="disableSourceControlIntegration" value="true" />
</solution>
</configuration>
.sln
's folder and create a new text file and name it .tfignore
(if using Windows Explorer, use the same trick as above and name it .tfignore.
).tfignore:
# Ignore the NuGet packages folder in the root of the repository.
# If needed, prefix 'packages' with additional folder names if it's
# not in the same folder as .tfignore.
packages
# include package target files which may be required for msbuild,
# again prefixing the folder name as needed.
!packages/*.targets
.tfignore
file and .nuget
folder to all of my various solutions and committed them and I no longer have the packages
folder trying to sneak into my source control repo!While not mine, I have found this .tfignore
template by sirkirby to be handy. The example in my answer covers the Nuget packages
folder but this template includes some other things as well as provides additional examples that can be useful if you wish to customize this further.

Anyways, the only improvement I have to point out is about avoiding extra blank column in excel after paste. Adding one line dataGridView1.RowHeadersVisible = false;
hides so called "Row Header" which appears on the left most part of DataGridView, and so it is not selected and copied to clipboard when you do dataGridView1.SelectAll();
private void copyAlltoClipboard()
{
//to remove the first blank column from datagridview
dataGridView1.RowHeadersVisible = false;
dataGridView1.SelectAll();
DataObject dataObj = dataGridView1.GetClipboardContent();
if (dataObj != null)
Clipboard.SetDataObject(dataObj);
}
private void button3_Click_1(object sender, EventArgs e)
{
copyAlltoClipboard();

Assuming that you have and trust (to be authoritative) the list of escape characters Java regex uses (would be nice if these characters were exposed in some Pattern class member) you can use the following method to escape the character if it is indeed necessary:
private static final char[] escapeChars = { '<', '(', '[', '{', '\\', '^', '-', '=', '$', '!', '|', ']', '}', ')', '?', '*', '+', '.', '>' };
private static String regexEscape(char character) {
for (char escapeChar : escapeChars) {
if (character == escapeChar) {
return "\\" + character;
}
}
return String.valueOf(character);
}
As many others have answered: Java doesn't support user-defined operator overloading.
Maybe this is off-topic, but I want to comment on some things I read in some answers.
About readability.
Compare:
Look again!
Which one is more readable?
A programming language that allows the creation of user-defined types, should allow them to act in the same way as the built-in types (or primitive types).
So Java breaks a fundamental principle of Generic Programming:
We should be able to interchange objects of built-in types with objects of user-defined types.
(You may be wondering: "Did he say 'objects of built-in'?". Yes, see here.)
About String concatenation:
Mathematicians use the symbol + for commutative operations on sets.
So we can be sure that a + b = b + a.
String concatenation (in most programming languages) doesn't respect this common mathematical notation.
a := "hello"; b := "world"; c := (a + b = b + a);
or in Java:
String a = "hello"; String b = "world"; boolean c = (a + b).equals(b + a);
Extra:
Notice how in Java equality and identity are confused.
The == (equality) symbol means:
a. Equality for primitive types.
b. Identity-check for user-defined types, therefore, we are forced to use the function equals() for equality.
But... What has this to do with operator overloading?
If the language allows the operator overloading the user could give the proper meaning to the equality operator.
There are a lot of things in C that aren't technically needed because they can be more or less easily implemented in terms of other things. Here is an incomplete list:
Imagine what your code would look like without these and you may find your answer. The ternary operator is a form of "syntactic sugar" that if used with care and skill makes writing and understanding code easier.
If you want to know the location of you NPM packages, you should:
which npm // locate a program file in the user's path SEE man which
// OUTPUT SAMPLE
/usr/local/bin/npm
la /usr/local/bin/npm // la: aliased to ls -lAh SEE which la THEN man ls
lrwxr-xr-x 1 t04435 admin 46B 18 Sep 10:37 /usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
So given that npm is a NODE package itself, it is installed in the same location as other packages(EUREKA). So to confirm you should cd into node_modules and list the directory.
cd /usr/local/lib/node_modules/
ls
#SAMPLE OUTPUT
@angular npm .... all global npm packages installed

I suddenly had the same problem, after no noteworthy changes.
I solved it by deleting the app/build

Here's an approach using generators:
function* square(n) {
for (var i = 0; i < n; i++ ) yield i*i;
}
Then you can write
console.log(...square(7));
Another idea is:
[...Array(5)].map((_, i) => i*i)
Array(5)
creates an unfilled five-element array. That's how Array
works when given a single argument. We use the spread operator to create an array with five undefined elements. That we can then map. See http://ariya.ofilabs.com/2013/07/sequences-using-javascript-array.html.
Alternatively, we could write
Array.from(Array(5)).map((_, i) => i*i)
or, we could take advantage of the second argument to Array#from
to skip the map
and write
Array.from(Array(5), (_, i) => i*i)
A horrible hack which I saw recently, which I do not recommend you use, is
[...1e4+''].map((_, i) => i*i)

Ok so if I understand well you're trying to get a random string password which contains 5 letters and 3 numbers randomly positioned and so which has a length of 8 characters and you accept maj and min letters, you can do that with the following function:
function randPass(lettersLength,numbersLength) {
var j, x, i;
var result = '';
var letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
var numbers = '0123456789';
for (i = 0; i < lettersLength; i++ ) {
result += letters.charAt(Math.floor(Math.random() * letters.length));
}
for (i = 0; i < numbersLength; i++ ) {
result += numbers.charAt(Math.floor(Math.random() * numbers.length));
}
result = result.split("");
for (i = result.length - 1; i > 0; i--) {
j = Math.floor(Math.random() * (i + 1));
x = result[i];
result[i] = result[j];
result[j] = x;
}
result = result.join("");
return result
}
function randPass(lettersLength,numbersLength) {_x000D_
var j, x, i;_x000D_
var result = '';_x000D_
var letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';_x000D_
var numbers = '0123456789';_x000D_
for (i = 0; i < lettersLength; i++ ) {_x000D_

Docker requires your command to keep running in the foreground. Otherwise, it thinks that your applications stops and shutdown the container.
So if your docker entry script is a background process like following:
/usr/local/bin/confd -interval=30 -backend etcd -node $CONFIG_CENTER &
The '&' makes the container stop and exit if there are no other foreground process triggered later. So the solution is just remove the '&' or have another foreground CMD running after it, such as
tail -f server.log
The data members and function members that operate on the instance of the type are called instance members. The int’s ToString method (for example) are examples of instance members. By default, members are instance members. Data members and function members that don’t operate on the instance of the type, but rather on the type itself, must be marked as static. The Test.Main and Console.WriteLine methods are static methods. The Console class is actually a static class, which means all its members are static. You never actually create instances of a Console—one console is shared across the whole application.

If you dig into NSInteger's implementation:
#if __LP64__
typedef long NSInteger;
#else
typedef int NSInteger;
#endif
Simply, the NSInteger typedef does a step for you: if the architecture is 32-bit, it uses int
, if it is 64-bit, it uses long
. Using NSInteger, you don't need to worry about the architecture that the program is running on.

) or current document (in case of link
) and the destination anchor or resource defined by this attribute. When we write:
<link href="style.css" rel="stylesheet" />
The browser understands that this resource is a stylesheet and the processing parsing of the page is not paused (rendering might be paused since the browser needs the style rules to paint and render the page). It is not similar to dumping the contents of the css file inside the style
tag. (Hence it is advisable to use link
rather than @import
for attaching stylesheets to your html document.)
src (Source) attribute just embeds the resource in the current document at the location of the element's definition. For eg. When the browser finds
<script src="script.js"></script>
The loading and processing of the page is paused until this the browser fetches, compiles and executes the file. It is similar to dumping the contents of the js file inside the script
tag. Similar is the case with img
tag. It is an empty tag and the content, that should come inside it, is defined by the src
attribute. The browser pauses the loading until it fetches and loads the image. [so is the case with iframe
]
This is the reason why it is advisable to load all JavaScript files at the bottom (before the </body>
tag)
update : Refer @John-Yin's answer for more info on how it is implemented as per HTML 5 specs.
Like Jon Skeet says, use the Process.Exited
:
proc.StartInfo.FileName = exportPath + @"\" + fileExe;
proc.Exited += new EventHandler(myProcess_Exited);
proc.Start();
inProcess = true;
while (inProcess)
{
proc.Refresh();
System.Threading.Thread.Sleep(10);
if (proc.HasExited)
{
inProcess = false;
}
}
private void myProcess_Exited(object sender, System.EventArgs e)
{
inProcess = false;
Console.WriteLine("Exit time: {0}\r\n" +
"Exit code: {1}\r\n", proc.ExitTime, proc.ExitCode);
}
You need to give a function to be called after the time delay as the second argument to after
:
after(delay_ms, callback=None, *args)
Registers an alarm callback that is called after a given time.
So what you really want to do is this:
tiles_letter = ['a', 'b', 'c', 'd', 'e']
def add_letter():
rand = random.choice(tiles_letter)
tile_frame = Label(frame, text=rand)
tile_frame.pack()
root.after(500, add_letter)
tiles_letter.remove(rand) # remove that tile from list of tiles
root.after(0, add_letter) # add_letter will run as soon as the mainloop starts.
root.mainloop()
You also need to schedule the function to be called again by repeating the call to after
inside the callback function, since after
only executes the given function once. This is also noted in the documentation:
The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself
Note that your example will throw an exception as soon as you've exhausted all the entries in tiles_letter
, so you need to change your logic to handle that case whichever way you want. The simplest thing would be to add a check at the beginning of add_letter
to make sure the list isn't empty, and just return
if it is:
def add_letter():
if not tiles_letter:
return
rand = random.choice(tiles_letter)
tile_frame = Label(frame, text=rand)
tile_frame.pack()
root.after(500, add_letter)
tiles_letter.remove(rand) # remove that tile from list of tiles

You can use the .input-group
class like this:
<div class="input-group">
<input type="text" class="form-control"/>
<span class="input-group-addon">
<i class="fa fa-search"></i>
</span>
</div>
You can use the .input-append
class like this:
<div class="input-append">
<input class="span2" type="text">
<button type="submit" class="btn">
<i class="icon-search"></i>
</button>
</div>
Both will look like this:

Ten years later and I had the same problem. I solved it in the following way:
That is all :)
As to me, i need to caffe to my python path. I can add it's path to the file
/home/xy/.bashrc
by add
export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH
.
to my /home/xy/.bashrc
file.
But when I use pycharm, the path is still not in.
So I can add path to PYTHONPATH
variable, by run -> edit Configuration.
To check the status of Hyper-v in Windows 10,
right click <"start"> ? Run ? OptionalFeatures.exe, ? look for the "Hyper-V" option.
The box should be empty, not checked or shaded.
Make sure to fully power down and reboot the host after changing the Hyper-v setting.
PS
Docker known for activating this "Hyper-V" without asking for user opinion and then Oracle VirtualBox does not want to work.
I know this is really old, but this is the simplest way to query for Map.
Simply implement the ResultSetExtractor interface to define what type you want to return. Below is an example of how to use this. You'll be mapping it manually, but for a simple map, it should be straightforward.
jdbcTemplate.query("select string1,string2 from table where x=1", new ResultSetExtractor<Map>(){
@Override
public Map extractData(ResultSet rs) throws SQLException,DataAccessException {
HashMap<String,String> mapRet= new HashMap<String,String>();
while(rs.next()){
mapRet.put(rs.getString("string1"),rs.getString("string2"));
}
return mapRet;
}
});
This will give you a return type of Map that has multiple rows (however many your query returned) and not a list of Maps. You can view the ResultSetExtractor docs here: http://docs.spring.io/spring-framework/docs/2.5.6/api/org/springframework/jdbc/core/ResultSetExtractor.html
you can save them into a $_SESSION variable and then when the user calls that page again populate all the inputs with their respective session variables.
To update each submodule, you could invoke the following command (at the root of the repository):
git submodule -q foreach git pull -q origin master
You can remove the -q option to follow the whole process.
You can very easily iterate over dictionaries, too:
for team, scores in NL_East.iteritems():
runs_scored = float(scores[0])
runs_allowed = float(scores[1])
win_percentage = round((runs_scored**2)/((runs_scored**2)+(runs_allowed**2))*1000)
print '%s: %.1f%%' % (team, win_percentage)
When you create any activity in android file you have to specify it in AndroidManifest.xml like
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".MyCreativityActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".OrderScreen"></activity>
</application>
This is how you can add .jar
file in Android Studio 2.1.3.
I was also facing the same issue

I can't seem to find where my code has gone wrong. Here is my full error:
Parse error: syntax error, unexpected T_VARIABLE on line x
What I am trying
$sql = 'SELECT * FROM dealer WHERE id="'$id.'"';
Answer
Parse error: A problem with the syntax of your program, such as leaving a semicolon off of the end of a statement or, like the case above, missing the .
operator. The interpreter stops running your program when it encounters a parse error.
In simple words this is a syntax error, meaning that there is something in your code stopping it from being parsed correctly and therefore running.
What you should do is check carefully at the lines around where the error is for any simple mistakes.
That error message means that in line x of the file, the PHP interpreter was expecting to see an open parenthesis but instead, it encountered something called T_VARIABLE
. That T_VARIABLE
thing is called a token
. It's the PHP interpreter's way of expressing different fundamental parts of programs. When the interpreter reads in a program, it translates what you've written into a list of tokens. Wherever you put a variable in your program, there is aT_VARIABLE
token in the interpreter's list.
Good read: List of Parser Tokens
So make sure you enable at least E_PARSE
in your php.ini
. Parse errors should not exist in production scripts.
I always recommended to add the following statement, while coding:
error_reporting(E_ALL);
Also, a good idea to use an IDE which will let you know parse errors while typing. You can use:

The tutorial is cheating because it is starting with a greyscale image encoded in RGB, so they are just slicing a single color channel and treating it as greyscale. The basic steps you need to do are to transform from the RGB colorspace to a colorspace that encodes with something approximating the luma/chroma model, such as YUV/YIQ or HSL/HSV, then slice off the luma-like channel and use that as your greyscale image. matplotlib
does not appear to provide a mechanism to convert to YUV/YIQ, but it does let you convert to HSV.
Try using matplotlib.colors.rgb_to_hsv(img)
then slicing the last value (V) from the array for your grayscale. It's not quite the same as a luma value, but it means you can do it all in matplotlib
.
Background:
Alternatively, you could use PIL or the builtin colorsys.rgb_to_yiq()
to convert to a colorspace with a true luma value. You could also go all in and roll your own luma-only converter, though that's probably overkill.

Based on @EdChum's answer, you can try the following solution:
df[df.columns[pd.Series(df.columns).str.contains("foo")]]
This will be really helpful in case not all the columns you want to select start with foo
. This method selects all the columns that contain the substring foo
and it could be placed in at any point of a column's name.
In essence, I replaced .startswith()
with .contains()
.
You need to read and write document.cookie
if (document.cookie.indexOf("visited=") >= 0) {
// They've been here before.
alert("hello again");
}
else {
// set a new cookie
expiry = new Date();
expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes
// Date()'s toGMTSting() method will format the date correctly for a cookie
document.cookie = "visited=yes; expires=" + expiry.toGMTString();
alert("this is your first time");
}

Yes, you can use json_encode
to take your HTML string and escape it as necessary.
Note that in JSON, the top level item must be an array or object (that's not true anymore), it cannot just be a string. So you'll want to create an object and make the HTML string a property of the object (probably the only one), so the resulting JSON looks something like:
{"html": "<p>I'm the markup</p>"}
I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value
directly without relating to additional objects.
my solution is a sum up of everything above with little tricks I added, basically I added this to my html code
<script>var exports = {"__esModule": true};</script>
<script src="js/file.js"></script>
this even allows you to use import
instead of require
if you're using electron or something, and it works fine with typescript 3.5.1, target: es3 -> esnext.
As an addition to Darin Dimitrov's answer:
If you only want this particular line to use a certain (different from standard) format, you can use in MVC5:
@Html.EditorFor(model => model.Property, new {htmlAttributes = new {@Value = @Model.Property.ToString("yyyy-MM-dd"), @class = "customclass" } })
Because the operating system may not do so. The flush operation forces the file data into the file cache in RAM, and from there it's the OS's job to actually send it to the disk.
I would go for it.next()
for the simple reason that next()
is guaranteed to be implemented, while remove()
is an optional operation.
E next()
Returns the next element in the iteration.
void remove()
Removes from the underlying collection the last element returned by the iterator (optional operation).
This answer is for the impatient/ have deadlines to meet to, only a part/simple explanation is below:
So
in C++, with name mangling uniquely identities each function
in C, even without name mangling uniquely identities each function
To change the behaviour of C++, that is, to specify that name mangling should not happen for a particular function, you can use extern "C" before the function name, for whatever reason, like exporting a function with a specific name from a dll, for use by its clients.

In my case i forgot to add the () after the function name inside the render function of a react component
public render() {
let ctrl = (
<>
<div className="aaa">
{this.renderView}
</div>
</>
);
return ctrl;
};
private renderView() : JSX.Element {
// some html
};
Changing the render method, as it states in the error message to
<div className="aaa">
{this.renderView()}
</div>
fixed the problem
If the only characters to consider are letters then you can do:
select X from myTable where upper(X) = lower(X)
But of course that won't filter out other characters, just letters.
The previous answers were in the right track, but the complete answer for this is going to Disabling rules only for a group of files, there you'll find the documentation needed to disable/enable rules for certain folders (Because in some cases you don't want to ignore the whole thing, only disable certain rules). Example:
{
"env": {},
"extends": [],
"parser": "",
"plugins": [],
"rules": {},
"overrides": [
{
"files": ["test/*.spec.js"], // Or *.test.js
"rules": {

You need to use overflow option like below:
.nav{
max-height: 300px;
overflow-y: scroll;
}
Change the height according to amount of items you need to show
Span starts out as an inline element. You can change its display attribute to block, for instance, and its height/width attributes will start to take effect.
The solution from parisjohn above works fine with me. Plus the code looks clean and easy to understand. In my case there are a few functions to call using Pool, so I modified parisjohn's code a bit below. I made call to be able to call several functions, and the function names are passed in the argument dict from go()
:
from multiprocessing import Pool
class someClass(object):
def __init__(self):
pass
def f(self, x):
return x*x
def g(self, x):
return x*x+1
def go(self):
p = Pool(4)
sc = p.map(self, [{"func": "f", "v": 1}, {"func": "g", "v": 2}])
print sc
def __call__(self, x):
if x["func"]=="f":
return self.f(x["v"])
if x["func"]=="g":
return self.g(x["v"])
sc = someClass()
sc.go()

Performance to be compared with the for loop version of Goran.it answer.
Vadim Shender response is great. You can also use a simpler decorator like below:
import datetime
def calc_timing(original_function):
def new_function(*args,**kwargs):
start = datetime.datetime.now()
x = original_function(*args,**kwargs)
elapsed = datetime.datetime.now()
print("Elapsed Time = {0}".format(elapsed-start))
return x
return new_function()
@calc_timing
def a_func(*variables):
print("do something big!")
Sub AddColor()
For Each cell In Selection
R = Round(cell.Value)
G = Round(cell.Offset(0, 1).Value)
B = Round(cell.Offset(0, 2).Value)
Cells(cell.Row, 1).Resize(1, 4).Interior.Color = RGB(R, G, B)
Next cell
End Sub
Assuming that there are 3 columns R, G and B (in this order). Select first column ie R. press alt+F11 and run the above code. We have to select the first column (containing R or red values) and run the code every time we change the values to reflect the changes.
I hope this simpler code helps !
Despite following the accepted answer exactly, I was still unable to get the service to start-- I was instead given a failure message during installation stating that the service that was just installed could not be started, as it did not exist, despite using this.serviceInstaller.ServiceName
rather than a literal...
I eventually found an alternative solution that makes use of the command line:
private void serviceInstaller_AfterInstall(object sender, InstallEventArgs e) {
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C sc start " + this.serviceInstaller.ServiceName;
Process process = new Process();
process.StartInfo = startInfo;
process.Start();
}
The following are the ways we can use to check the dependencies:
Method 1: Using sp_depends
sp_depends 'dbo.First'
GO
Method 2: Using information_schema.routines
SELECT *
FROM information_schema.routines ISR
WHERE CHARINDEX('dbo.First', ISR.ROUTINE_DEFINITION) > 0
GO
Method 3: Using DMV sys.dm_sql_referencing_entities
SELECT referencing_schema_name, referencing_entity_name,
referencing_id, referencing_class_desc, is_caller_dependent
FROM sys.dm_sql_referencing_entities ('dbo.First', 'OBJECT');
GO
from datetime import datetime,timedelta
today=datetime.today()

yesterday=today-datetime,timedelta(days=1)
print("Yesterday date:",yesterday)
tommorrow=today+datetime.timedelta(days=1)
print("Tommorrow Date:",tommorrow)
the
:checked
pseudo-class initially applies to such elements that have the HTML4selected
andchecked
attributes
Source: w3.org
So, this CSS works, although styling the color
is not possible in every browser:
option:checked { color: red; }
An example of this in action, hiding the currently selected item from the drop down list.
option:checked { display:none; }
_x000D_
<select>_x000D_
<option>A</option>_x000D_
<option>B</option>_x000D_
<option>C</option>_x000D_
</select>
_x000D_
To style the currently selected option in the closed dropdown as well, you could try reversing the logic:
select { color: red; }
option:not(:checked) { color: black; } /* or whatever your default style is */
I did it like this. For group named Editor
.
# views.py
def index(request):
current_user_groups = request.user.groups.values_list("name", flat=True)
context = {
"is_editor": "Editor" in current_user_groups,
}
return render(request, "index.html", context)
template
# index.html
{% if is_editor %}
<h1>Editor tools</h1>
{% endif %}
NOTE: Programs compiled with high-optimization levels (-O3, -O4) cannot generate many debugging symbols for optimized variables, in-lined functions and unrolled loops, regardless of the symbols being embedded (-g) or extracted (objcopy) into a '.debug' file.
Alternate approaches are
The first option provides a means to rebuild the production code with full debugging and symbols at a later date. Being able to re-build the original production code with no optimizations is a tremendous help for debugging. (NOTE: This assumes testing was done with the optimized version of the program).
Your build system can create a .c file loaded with the compile date, commit, and other VCS details. Here is a 'make + git' example:
program: program.o version.o
program.o: program.cpp program.h
build_version.o: build_version.c
build_version.c:
@echo "const char *build1=\"VCS: Commit: $(shell git log -1 --pretty=%H)\";" > "$@"
@echo "const char *build2=\"VCS: Date: $(shell git log -1 --pretty=%cd)\";" >> "$@"
@echo "const char *build3=\"VCS: Author: $(shell git log -1 --pretty="%an %ae")\";" >> "$@"
@echo "const char *build4=\"VCS: Branch: $(shell git symbolic-ref HEAD)\";" >> "$@"
# TODO: Add compiler options and other build details
.TEMPORARY: build_version.c
After the program is compiled you can locate the original 'commit' for your code by using the command: strings -a my_program | grep VCS
VCS: PROGRAM_NAME=my_program
VCS: Commit=190aa9cace3b12e2b58b692f068d4f5cf22b0145
VCS: BRANCH=refs/heads/PRJ123_feature_desc
VCS: AUTHOR=Joe Developer [email protected]
VCS: COMMIT_DATE=2013-12-19
All that is left is to check-out the original code, re-compile without optimizations, and start debugging.
If you need to mock a static method, it is a strong indicator for a bad design. Usually, you mock the dependency of your class-under-test. If your class-under-test refers to a static method - like java.util.Math#sin for example - it means the class-under-test needs exactly this implementation (of accuracy vs. speed for example). If you want to abstract from a concrete sinus implementation you probably need an Interface (you see where this is going to)?
The accepted answer does not work.
If your page loads URLs via Javascript, the navigationType
will be UIWebViewNavigationTypeOther

Create a Game model which extends Eloquent and use this:
Game::take(30)->skip(30)->get();
take()
here will get 30 records and skip()
here will offset to 30 records.
In recent Laravel versions you can also use:
Game::limit(30)->offset(30)->get();

The insert statement actually has a syntax for doing just that. It's a lot easier if you specify the column names rather than selecting "*" though:
INSERT INTO new_table (Foo, Bar, Fizz, Buzz)
SELECT Foo, Bar, Fizz, Buzz
FROM initial_table
-- optionally WHERE ...
I'd better clarify this because for some reason this post is getting a few down-votes.
The INSERT INTO ... SELECT FROM syntax is for when the table you're inserting into ("new_table" in my example above) already exists. As others have said, the SELECT ... INTO syntax is for when you want to create the new table as part of the command.
You didn't specify whether the new table needs to be created as part of the command, so INSERT INTO ... SELECT FROM should be fine if your destination table already exists.
I use apache common IO to read a text file into a single string

simple and "clean". you can even set encoding of the text file with no hassle.
String str = FileUtils.readFileToString(file, "UTF-8");
Since uintptr_t
is not guaranteed to be there in C++/C++11, if this is a one way conversion you can consider uintmax_t
, always defined in <cstdint>
.
auto real_param = reinterpret_cast<uintmax_t>(param);
To play safe, one could add anywhere in the code an assertion:
static_assert(sizeof (uintmax_t) >= sizeof (void *) ,
"No suitable integer type for conversion from pointer type");

Using VS2013 just tested this and it appears reliable and consistent. This is similar to some comments above but adds another method that's quicker.
(1st) In Windows File Explorer highlight and copy all 3 Form files (.vb or .cs, .designer, .resx)
(2nd) This can be accomplished 2 ways:
(2a-1) In File Explorer paste the 3 files into the project folder with your other forms
(2a-2) In VS Solution Explorer, turn 'Show All Files' on, Right Click on the pasted form & 'Include in Project'. It should work without other changes.
Or, I think better:
(2b-1) In VS, click into Solution Explorer and paste w/Control-C. (For some reason the right-click context menu in Solution Explorer may not show a paste option, but it works from the keyboard.) This method adds the form to the project directly without having to 'Include in Project' as above. With this method you can add as many forms at a time as you like (all 3 files for each) in a single step.
If using 4.5+ Framework I would use ReadOnlyDictionary (also ReadOnly Collection for lists) to do readonly mappings/constants. It's implemented in the following way.
static class SomeClass
{
static readonly ReadOnlyDictionary<string,int> SOME_MAPPING
= new ReadOnlyDictionary<string,int>(
new Dictionary<string,int>()
{
{ "One", 1 },
{ "Two", 2 }
}
)
}
SQLAlchemy introduced that in version 1.0.0
:
Bulk operations - SQLAlchemy docs
With these operations, you can now do bulk inserts or updates!
For instance, you can do:
s = Session()
objects = [
User(name="u1"),
User(name="u2"),
User(name="u3")

Here, a bulk insert will be made.
I had the same problem. Solution in my case: run CMD as ADMINISTRATOR. then type and execute: "lsnrctl start" wait about 2 minutes then should work. (in my case was only 50 seconds, but just to be on the safe side)
I also faced similar issue here is the details when uploading logo using dropdown logo upload box
<div>
<div class="uploader greyLogoBox" id="uploader" flex="64" onclick="$('#filePhoto').click()">
<img id="imageBox" src="{{ $ctrl.companyLogoUrl }}" alt=""/>
<input type="file" name="userprofile_picture" id="filePhoto" ngf-select="$ctrl.createUploadLogoRequest()"/>
<md-icon ng-if="!$ctrl.isLogoPresent" class="upload-icon" md-font-set="material-icons">cloud_upload</md-icon>
<div ng-if="!$ctrl.isLogoPresent" class="text">Drag and drop a file here, or click to upload</div>
</div>
<script type="text/javascript">
var imageLoader = document.getElementById('filePhoto');
imageLoader.addEventListener('change', handleImage, false);
function handleImage(e) {
var reader = new FileReader();
reader.onload = function (event) {
$('.uploader img').attr('src',event.target.result);
}
reader.readAsDataURL(e.target.files[0]);
}
</script>
</div>

.uploader {
position:relative;
overflow:hidden;
height:100px;
max-width: 75%;
margin: auto;
text-align: center;

}
.drag-drop-zone {

}
}
.uploader img{
max-width: 464px;
max-height: 100px;
z-index:1;

}
.greyLogoBox {

#filePhoto{
position:absolute;
width:464px;
height:100px;
left:0;
top:0;
z-index:2;
opacity:0;
cursor:pointer;
}
before correction my code was :
function handleImage(e) {
var reader = new FileReader();
reader.onload = function (event) {
onclick="$('#filePhoto').click()"
$('.uploader img').attr('src',event.target.result);
}
reader.readAsDataURL(e.target.files[0]);
}
The error in console:
I solved it by removing onclick="$('#filePhoto').click()"
from div tag.
Having the following XML:
<node>Text1<subnode/>text2</node>
How do I select either the first or the second text node via XPath?
Use:
/node/text()
This selects all text-node children of the top element (named "node") of the XML document.
/node/text()[1]
This selects the first text-node child of the top element (named "node") of the XML document.
/node/text()[2]
This selects the second text-node child of the top element (named "node") of the XML document.
/node/text()[someInteger]
This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:
/node/text()[position() = someInteger]
Use count(d.ertek)
or count(d.id)
instead of count(d)
. This can be happen when you have composite primary key at your entity.
Without seeing said object list, I believe you should be binding to the DataGrid's ItemsSource
property, not its DataContext
.
<DataGrid x:Name="Imported" VerticalAlignment="Top" ItemsSource="{Binding Source=list}" AutoGenerateColumns="False" CanUserResizeColumns="True">
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
<DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
</DataGrid.Columns>
</DataGrid>
(This assumes that the element [UserControl, etc.] that contains the DataGrid has its DataContext bound to an object that contains the list
collection. The DataGrid is derived from ItemsControl
, which relies on its ItemsSource
property to define the collection it binds its rows to. Hence, if list
isn't a property of an object bound to your control's DataContext, you might need to set both DataContext={Binding list}
and ItemsSource={Binding list}
on the DataGrid...)
Here's a more valid way which also check if your textbox is filled with only blanks.
// When spaces are not allowed
if (string.IsNullOrWhiteSpace(txtBox1.Text) || string.IsNullOrWhiteSpace(txtBox2.Text))
//...give error...
// When spaces are allowed
if (string.IsNullOrEmpty(txtBox1.Text) || string.IsNullOrEmpty(txtBox2.Text))
//...give error...
The edited answer of @Habib.OSU is also fine, this is just another approach.
The easiest way is probably with VLOOKUP()
. This will require the 2nd worksheet to have the employee number column sorted though. In newer versions of Excel, apparently sorting is no longer required.
For example, if you had a "Sheet2" with two columns - A = the employee number, B = the employee's name, and your current worksheet had employee numbers in column D and you want to fill in column E, in cell E2, you would have:
=VLOOKUP($D2, Sheet2!$A$2:$B$65535, 2, FALSE)
Then simply fill this formula down the rest of column D.
Explanation:
$D2
specifies the value to search for.Sheet2!$A$2:$B$65535
specifies the range of cells to search in. Excel will search for the value in the first column of this range (in this case Sheet2!A2:A65535
). Note I am assuming you have a header cell in row 1.2
specifies a 1-based index of the column to return from within the searched range. The value of 2
will return the second column in the range Sheet2!$A$2:$B$65535
, namely the value of the B
column.FALSE
says to only return exact matches.This worked for me. Put your cursor at the beginning of the word you want to replace, then
CtrlK, CtrlD, CtrlD ...
That should select as many instances of the word as you like, then you can just type the replacement.
Alternative answer, you can use this JDBC URL directly in your datasource configuration:
jdbc:mysql://yourserver:3306/yourdatabase?zeroDateTimeBehavior=convertToNull
Edit:
Datetimes with all-zero components (0000-00-00 ...) — These values can not be represented reliably in Java. Connector/J 3.0.x always converted them to NULL when being read from a ResultSet.
Connector/J 3.1 throws an exception by default when these values are encountered as this is the most correct behavior according to the JDBC and SQL standards. This behavior can be modified using the zeroDateTimeBehavior configuration property. The allowable values are:
- exception (the default), which throws an SQLException with an SQLState of S1009.
- convertToNull, which returns NULL instead of the date.
- round, which rounds the date to the nearest closest value which is 0001-01-01.
Update: Alexander reported a bug affecting mysql-connector-5.1.15 on that feature. See CHANGELOGS on the official website.
UPDATE will not do anything if the row does not exist.
Where as the INSERT OR REPLACE would insert if the row does not exist, or replace the values if it does.
Option using dplyr
require(dplyr)
dt<-as.data.frame(matrix(runif(10*10),10,10))
dt <- select(dt, -V1, -V2, -V3, -V4)
cor(dt)
If someone else is looking how to stop Flask server inside win32 service - here it is. It's kinda weird combination of several approaches, but it works well. Key ideas:
shutdown
endpoint which can be used for graceful shutdown. Note: it relies on request.environ.get
which is usable only inside web request's context (inside @app.route
-ed function)SvcStop
method uses requests
to do HTTP request to the service itself.myservice_svc.py
import win32service
import win32serviceutil
import win32event
import servicemanager
import time
import traceback
import os
import myservice
class MyServiceSvc(win32serviceutil.ServiceFramework):
_svc_name_ = "MyServiceSvc" # NET START/STOP the service by the following name
_svc_display_name_ = "Display name" # this text shows up as the service name in the SCM
_svc_description_ = "Description" # this text shows up as the description in the SCM
def __init__(self, args):
os.chdir(os.path.dirname(myservice.__file__))
win32serviceutil.ServiceFramework.__init__(self, args)
def SvcDoRun(self):
# ... some code skipped
myservice.start()
def SvcStop(self):
"""Called when we're being shut down"""
myservice.stop()
# tell the SCM we're shutting down
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
servicemanager.PYS_SERVICE_STOPPED,
(self._svc_name_, ''))
if __name__ == '__main__':
os.chdir(os.path.dirname(myservice.__file__))
win32serviceutil.HandleCommandLine(MyServiceSvc)

def shutdown():
shutdown_func = request.environ.get('werkzeug.server.shutdown')
if shutdown_func is None:
raise RuntimeError('Not running werkzeug')
shutdown_func()
return "Shutting down..."

resp = requests.get('http://localhost:5001/shutdown')
200 (cache) means Firefox is simply using the locally cached version. This is the fastest because no request to the Web server is made.
304 means Firefox is sending a "If-Modified-Since" conditional request to the Web server. If the file has not been updated since the date sent by the browser, the Web server returns a 304 response which essentially tells Firefox to use its cached version. It is not as fast as 200 (cache) because the request is still sent to the Web server, but the server doesn't have to send the contents of the file.
To your last question, I don't know why the two JavaScript files in the same directory are returning different results.
You have to select and send the form data as well:
$("#post-btn").click(function(){
$.post("process.php", $("#reg-form").serialize(), function(data) {
alert(data);
});
});
Take a look at the documentation for the jQuery serialize
method, which encodes the data from the form fields into a data-string to be sent to the server.
search your code you must be referring to color in color.xml
in an xml drawable.
go and give hex code instead of referencing....
Example:
in drawable.xml
you must have called
android:fillColor="@color/blue"
change it to android:fillColor="#ffaacc"
hope it solve your problem...
if version < 8.4.0
pg_dump -D -t <table> <database>
Add -a
before the -t
if you only want the INSERTs, without the CREATE TABLE etc to set up the table in the first place.
version >= 8.4.0
pg_dump --column-inserts --data-only --table=<table> <database>
getattr
calls method by name from an object.
But this object should be parent of calling class.
The parent class can be got by super(self.__class__, self)
class Base:
def call_base(func):
"""This does not work"""
def new_func(self, *args, **kwargs):
name = func.__name__
getattr(super(self.__class__, self), name)(*args, **kwargs)
return new_func
def f(self, *args):
print(f"BASE method invoked.")
def g(self, *args):
print(f"BASE method invoked.")
class Inherit(Base):
@Base.call_base
def f(self, *args):
"""function body will be ignored by the decorator."""
pass
@Base.call_base
def g(self, *args):
"""function body will be ignored by the decorator."""
pass
Inherit().f() # The goal is to print "BASE method invoked."
There are lots of solutions:
b = Arrays.copyOf(a, a.length);
Which allocates a new array, copies over the elements of a
, and returns the new array.
Or
b = new int[a.length];
System.arraycopy(a, 0, b, 0, b.length);
Which copies the source array content into a destination array that you allocate yourself.
Or
b = a.clone();
which works very much like Arrays.copyOf()
. See this thread.
Or the one you posted, if you reverse the direction of the assignment in the loop:
b[i] = a[i]; // NOT a[i] = b[i];
Basically you have two ways to iterate over all elements:
1. Using recursion (the most common way I think):
public static void main(String[] args) throws SAXException, IOException,
ParserConfigurationException, TransformerException {
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document document = docBuilder.parse(new File("document.xml"));
doSomething(document.getDocumentElement());
}
public static void doSomething(Node node) {
// do something with the current node instead of System.out
System.out.println(node.getNodeName());
NodeList nodeList = node.getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++) {
Node currentNode = nodeList.item(i);
if (currentNode.getNodeType() == Node.ELEMENT_NODE) {
//calls this method for all the children which is Element
doSomething(currentNode);
}
}
}
2. Avoiding recursion using getElementsByTagName()
method with *
as parameter:
public static void main(String[] args) throws SAXException, IOException,
ParserConfigurationException, TransformerException {
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document document = docBuilder.parse(new File("document.xml"));
NodeList nodeList = document.getElementsByTagName("*");
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
// do something with the current element
System.out.println(node.getNodeName());
}
}
}
I think these ways are both efficient.
Hope this helps.
