This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n
and the output of np.add.reduce()
are both scalars, this implies that the problem lies with xm
and ym
, the two of which are simply your x
and y
inputs minus their respective means.
Based on this, my guess is that your x
and y
inputs have different shapes from one another, making them incompatible for element-wise multiplication.
** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

----- 2016-07-04 MariaDB 10.2.1 -- Release Note -- -----
Support for DEFAULT with expressions (MDEV-10134).
----- 2018-10-22 8.0.13 General Availability -- -- -----
MySQL now supports use of expressions as default values in data type specifications. This includes the use of expressions as default values for the BLOB, TEXT, GEOMETRY, and JSON data types, which previously could not be assigned default values at all. For details, see Data Type Default Values.
If you're running on Passenger, then the default is to run in production, in your apache conf:
<VirtualHost *:80>
ServerName application_name.rails.local
DocumentRoot "/Users/rails/application_name/public"
RailsEnv production ## This is the default
</VirtualHost>
If you're just running a local server with mongrel or webrick, you can do:
./script/server -e production
or in bash:
RAILS_ENV=production ./script/server
actually overriding the RAILS_ENV constant in the enviornment.rb should probably be your last resort, as it's probably not going to stay set (see another answer I gave on that)
Create a Drawable XML file
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="@android:color/white" />
<stroke
android:width="1dp"
android:color="@color/md_white_1000" />
In your layout you add the drawable as a background on the imageView.
<ImageView
android:layout_width="200dp"
android:layout_height="200dp"
android:src="@drawable/photo"
android:background="@drawable/roundcorners"/>
Then you add this line in your Java code.
ImageView.setClipToOutline(true);
Note: this only works with level 21+
According to some developers, "Core Java" refers to package API java.util.*
, which is mostly used in coding.
The term "Core Java" is not defined by Sun, it's just a slang definition.
J2ME / J2EE still depend on J2SDK API's for compilation and execution.
Nobody would say java.util.*
is separated from J2SDK for usage.
If you want a (almost) one-liner:
from collections import deque d = {} deque((d.setdefault(year, []).append(value) for year, value in source_of_data), maxlen=0)
Using dict.setdefault
, you can encapsulate the idea of "check if the key already exists and make a new list if not" into a single call. This allows you to write a generator expression which is consumed by deque
as efficiently as possible since the queue length is set to zero. The deque will be discarded immediately and the result will be in d
.
This is something I just did for fun. I don't recommend using it. There is a time and a place to consume arbitrary iterables through a deque, and this is definitely not it.
I had a similar issue when performing a file download through Javascript. Adding the download attribute made no difference but adding target='_blank' did - I no longer get the 'Resource interpreted as Document...' console message.
Here's my nicely simple code:
var link = document.createElement('a');
link.target = '_blank';
link.href = url;
document.body.appendChild(link); // Required for Firefox
link.click();
link.remove();
I haven't tried it with direct HTML but would expect it to work.
Note I discovered that Firefox requires the link to be appended to the document whereas Chrome will work without it.
So I had the same problem because I wasn't in the right directory where my file was located. So when I ran javac Example.java
(for me) it said it couldn't find it. But I needed to go to where my Example.java
file was located. So I used the command cd
and right after that the location of the file. That worked for me. Tell me if it helps! Thanks!
No you can't set the image src attribute via CSS. The closest you can get is, as you say, background
or background-image
. I wouldn't recommend doing that anyway as it would be somewhat illogical.
However, there is a CSS3 solution available to you, if the browsers you're targeting are able to use it. Use content:url
as described in Pacerier's answer. You can find other, cross-browser solutions in the other answers below.
the declaration is generally the most 'useful', but that depends on how you want to use the class.
both is not valid.
Solution using Decorators that survives minification/uglification
We use code generation to decorate our Entity classes with metadata like so:
@name('Customer')
export class Customer {
public custId: string;
public name: string;
}
Then consume with the following helper:
export const nameKey = Symbol('name');
/**
* To perserve class name though mangling.
* @example
* @name('Customer')
* class Customer {}
* @param className
*/
export function name(className: string): ClassDecorator {
return (Reflect as any).metadata(nameKey, className);
}
/**
* @example
* const type = Customer;
* getName(type); // 'Customer'
* @param type
*/
export function getName(type: Function): string {
return (Reflect as any).getMetadata(nameKey, type);
}
/**
* @example
* const instance = new Customer();
* getInstanceName(instance); // 'Customer'
* @param instance
*/
export function getInstanceName(instance: Object): string {
return (Reflect as any).getMetadata(nameKey, instance.constructor);
}

From plt.imshow()
official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.
%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower', extent = [0, 10000, 0, 10], aspect = 1000)
Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.
plt.imshow(data, origin = 'lower', extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')
To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1]
and y_max - y_min = y_res * data.shape[0]
, where extent = [x_min, x_max, y_min, y_max]
. By default, aspect = 1
, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!
plt.imshow(data, origin = 'lower', extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower', extent = [0, 5, 0, 5])
The aspect of color pixel is x_res / y_res
. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])
) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower', extent = [0, 15, 0, 10], aspect = 1.5)
The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.
plt.imshow(data, origin = 'lower', extent = [0, 15, 0, 10], aspect = 1.2)
Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.

{
tv[i] = new TextView(this);
RelativeLayout.LayoutParams params=new RelativeLayout.LayoutParams
((int)LayoutParams.WRAP_CONTENT,(int)LayoutParams.WRAP_CONTENT);
params.leftMargin = 50;
params.topMargin = i*50;
tv[i].setText(str[i]);
tv[i].setTextSize((float) 20);
tv[i].setPadding(20, 50, 20, 50);
tv[i].setLayoutParams(params);
rl.addView(tv[i]);

Threads within the same process share the Memory, but each thread has its own stack and registers, and threads store thread-specific data in the heap. Threads never execute independently, so the inter-thread communication is much faster when compared to inter-process communication.
Processes never share the same memory. When a child process creates it duplicates the memory location of the parent process. Process communication is done by using pipe, shared memory, and message parsing. Context switching between threads is very slow.

Having used Mono, I would NOT recommend it. The Mono runtime is bundled with your app, so your apk ends up being bloated at more than 6MB. A better programming solution for C# would be dot42. Both Mono and dot42 are licensed products.
Personally, I would recommend using Java with the IntelliJ IDEA dev environment. I say this for 3 reasons:
I have been a C# programmer for 12 years and started developing for Android with C# but ended up jumping ship and going the Java route. The languages are so similar you really won't notice much of a learning curve.
P.S. If you want to use LINQ, serialization and other handy features that are native to C# then you just need to look for the equivalent java library.

VSCode is incredibly faster than VS. Files open instantly from Unity. VS is very slow. VSCode launches instantly. VS takes forever to launch.
VS can literally compile code, build apps and so on, it's a huge IDE like Unity itself or XCode. VSCode is indeed "just" a full-featured text editor. VSCode is NOT a compiler (far less a huge, build-everything system that can literally create apps and software of all types): VSCode is literally "just a text editor".
With VSCode, you DO need to install the "Visual Studio Code" package. (Not to be confused with the "Visual Studio" package.) (It seems to me that VS works fine without the VS package, but, with VS Code, you must install Unity's VSCode package.)
When you first download and install VSCode, simply open any C# file on your machine. It will instantly prompt you to install the needed C# package. This is harmless and easy.
Unfortunately VSCode generally has only one window! You cannot, really, easily drag files to separate windows. If this is important to you, you may need to go with VS.
The biggest problem with VS is that the overall concept of settings and preferences are absolutely horrible. In VS, it is all-but impossible to change the font, etc. In contrast, VSCode has FANTASTIC preferences - dead simple, never a problem.
As far as I can see, every single feature in VS which you use in Unity is present in VSCode. (So, code coloring, jump to definitions, it understands/autocompletes every single thing in Unity, it opens from Unity, double clicking something in the Unity console opens the file to that line, etc etc)
If you are used to VS. And you want to change to VSCode. It's always hard changing editors, they are so intimate, but it's pretty similar; you won't have a big heartache.
In short if you're a VS for Unity3D user,
and you're going to try VSCode...
VSCode is on the order of 19 trillion times faster in every way. It will blow your mind.
It does seem to have every feature.
Basically VS is the world's biggest IDE and application building system: VSCode is just an editor. (Indeed, that's exactly what you want with Unity, since Unity itself is the IDE.)
Don't forget to just click to install the relevant Unity package.
If I'm not mistaken, there is no reason whatsoever to use VS with Unity.
Unity is an IDE so you just need a text editor, and that is what VSCode is. VSCode is hugely better in both speed and preferences. The only possible problem - multiple-windows are a bit clunky in VSCode!
If you are using VS with Unity. There is an infuriating problem where often VS will try to open twice, that is you will end up with two or more copies of VS running. Nobody has ever been able to fix this or figure out what the hell causes it. Fortunately, this problem never happens with VSCode.
There are no installers, etc etc etc. On the download page, you download a zipped Mac app. Put it in the Applications folder and you're done.

To keep the "Explorer" list of files on the left tidy, in the Unity case:
I'd like to add that TypeGuards only work on strings or numbers, if you want to compare an object use instanceof

}
The best way I settled with is to set proxy environment variables right before using conda
or pip
install/update commands. Simply run:
set HTTP_PROXY=http://username:password@proxy_url:port
For example, your actual command could be like
set HTTP_PROXY=http://yourname:[email protected]_company.com:8080
If your company uses https proxy, then also
set HTTPS_PROXY=https://username:password@proxy_url:port
Once you exit Anaconda prompt then this setting is gone, so your username/password won't be saved after the session.
I didn't choose other methods mentioned in Anaconda documentation or some other sources, because they all require hardcoding of username/password into
.condarc
or .netrc
configuration files (also this won't work for PIP)All of these are unsafe and will require constant update later. And if you forget where to update? More troubleshooting will come your way...
Last one is not working now, take this one, it worked for me.

For extending control functionality like this, I like to use extension methods so that it can be reused easily. Here is a starter extensions file that contains an extension to disable sorting on a datagridview.
To use it, just include it in your project and call like this
myDatagridView.DisableSorting()

Imports System.ComponentModel

Imports System.Runtime.CompilerServices
Imports System.Windows.Forms

You can very easily override the val
function to trigger change by replacing it with a proxy to the original val
function.
just add This code somewhere in your document (after loading jQuery)
(function($){
var originalVal = $.fn.val;
$.fn.val = function(){
var result =originalVal.apply(this,arguments);
if(arguments.length>0)
$(this).change(); // OR with custom event $(this).trigger('value-changed');
return result;
};
})(jQuery);
A working example: here
(Note that this will always trigger change
when val(new_val)
is called even if the value didn't actually changed.)
If you want to trigger change ONLY when the value actually changed, use this one:
//This will trigger "change" event when "val(new_val)" called
//with value different than the current one
(function($){
var originalVal = $.fn.val;
$.fn.val = function(){
var prev;
if(arguments.length>0){
prev = originalVal.apply(this,[]);
}
var result =originalVal.apply(this,arguments);
if(arguments.length>0 && prev!=originalVal.apply(this,[]))
$(this).change(); // OR with custom event $(this).trigger('value-changed')
return result;
};
})(jQuery);

I know this was asked awhile back, but I found a comprehensive list of the virtual keyboard key codes right in MSDN, for use in C/C++. This also includes the mouse events. Note it is different than the javascript key codes (I noticed it around the VK_OEM section).
Here's the link:

Font's don't have a color; only when using the font you can set the color of the component. For example, when using a JTextArea:
JTextArea txt = new JTextArea();
Font font = new Font("Verdana", Font.BOLD, 12);
txt.setFont(font);
txt.setForeground(Color.BLUE);
According to this link, the createFont() method creates a new Font object with a point size of 1 and style PLAIN. So, if you want to increase the size of the Font, you need to do this:
Font font = Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"));
return font.deriveFont(12f);
If your threads don't do I/O, synchronization, etc., and there's nothing else running, 1 thread per core will get you the best performance. However that very likely not the case. Adding more threads usually helps, but after some point, they cause some performance degradation.
Not long ago, I was doing performance testing on a 2 quad-core machine running an ASP.NET application on Mono under a pretty decent load. We played with the minimum and maximum number of threads and in the end we found out that for that particular application in that particular configuration the best throughput was somewhere between 36 and 40 threads. Anything outside those boundaries performed worse. Lesson learned? If I were you, I would test with different number of threads until you find the right number for your application.
One thing for sure: 4k threads will take longer. That's a lot of context switches.
You should check your project facets in the project configuration. This is where you may uncheck the JSF dependency.
if result is None:
print "error parsing stream"
elif result:
print "result pass"
else:
print "result fail"
keep it simple and explicit. You can of course pre-define a dictionary.
messages = {None: 'error', True: 'pass', False: 'fail'}
print messages[result]
If you plan on modifying your simulate
function to include more return codes, maintaining this code might become a bit of an issue.
The simulate
might also raise an exception on the parsing error, in which case you'd either would catch it here or let it propagate a level up and the printing bit would be reduced to a one-line if-else statement.
For a similar situation I used this PKCS #5: Password-Based Cryptography Standard from RSA laboratories. You can avoid storing password, by substituting it with something that can be generated only from the password (in one sentence). There are some JavaScript implementations.

This answer took me forever to find as well. I discovered that all you have to do is concatenate the URL ('?' after the file name and extension) with the URL-encoded query string. It doesn't even look like you have to set the POST cURL options. See the fake example below:
//create URL
$exampleURL = 'http://www.example.com/example.php?';
// create curl resource
$ch = curl_init();
// build URL-encoded query string
$data = http_build_query(
array('first' => 'John', 'last' => 'Smith', '&'); // set url
curl_setopt($ch, CURLOPT_URL, $exampleURL . $data);
// return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources <br/>
curl_close($ch);
You can also use file_get_contents()

// read entire webpage file into a string
$output = file_get_contents($exampleURL . $data);
SJF are two type - i) non preemptive SJF ii)pre-emptive SJF
I have re-arranged the processes according to Arrival time. here is the non preemptive SJF
A.T= Arrival Time
B.T= Burst Time
C.T= Completion Time
T.T = Turn around Time = C.T - A.T
W.T = Waiting Time = T.T - B.T
Here is the preemptive SJF Note: each process will preempt at time a new process arrives.Then it will compare the burst times and will allocate the process which have shortest burst time. But if two process have same burst time then the process which came first that will be allocated first just like FCFS.
This doesn't work and it shouldn't because it would be a giant security hole.
Have a look at the new File System API. It allows you to request access to a virtual, sandboxed filesystem governed by the browser. You will have to request your user to "upload" their file into the sandboxed filesystem once, but afterwards you can work with it very elegantly.
While this definitely is the future, it is still highly experimental and only works in Google Chrome as far as CanIUse knows.
I found this answer very effective but not very easy to read for me.
To make it more clear you can invert the key and the value of a dictionary. This is make the keys values and the values keys, as seen here.
mydict = {'george':16,'amber':19}
res = dict((v,k) for k,v in mydict.iteritems())
print(res[16]) # Prints george
or
mydict = {'george':16,'amber':19}
dict((v,k) for k,v in mydict.iteritems())[16]
which is essentially the same that this other answer.
Well, it's fairly simple to do.
On the window resize event handler, calculate how much the window has grown/shrunk, and use that fraction to adjust 1) Height, 2) Width, 3) Canvas.Top, 4) Canvas.Left properties of all the child controls inside the canvas.
Here's the code:
private void window1_SizeChanged(object sender, SizeChangedEventArgs e)
{
myCanvas.Width = e.NewSize.Width;
myCanvas.Height = e.NewSize.Height;
double xChange = 1, yChange = 1;
if (e.PreviousSize.Width != 0)
xChange = (e.NewSize.Width/e.PreviousSize.Width);
if (e.PreviousSize.Height != 0)
yChange = (e.NewSize.Height / e.PreviousSize.Height);
foreach (FrameworkElement fe in myCanvas.Children )
{
/*because I didn't want to resize the grid I'm having inside the canvas in this particular instance. (doing that from xaml) */
if (fe is Grid == false)
{
fe.Height = fe.ActualHeight * yChange;
fe.Width = fe.ActualWidth * xChange;
Canvas.SetTop(fe, Canvas.GetTop(fe) * yChange);
Canvas.SetLeft(fe, Canvas.GetLeft(fe) * xChange);
}
}
}
I think this is shortest answer(but for constuctions like , you will have another discussion, I also have regex to convert "<bcm:info></bcm:info>"
to "<info></info>
" but it wasn't optimized, If someone ask me I will share it. So, my solution is:
public string RemoveAllNamespaces(string xmlDocument)
{
return Regex.Replace(xmlDocument, @"\sxmlns(\u003A\w+)?\u003D\u0022.+\u0022", " ");
}
Or you can do the same using sql query:
Click on SQL present along side Structure
TRUNCATE tablename; //offers better performance, but used only when all entries need to be cleared
or
DELETE FROM tablename; //returns the number of rows deleted
You should try detect the first line.
Then the:
if(n == 0){
line = words[n]+"\n";
}
I'm not sure, but maybe it helps.
Below code will help you
@Html.Label(@item.Date.Value.ToString("dd - M - yy"))
Both the other answers accomplish what you want.
You can use the pivot
functionality to arrange the data in a nice table
df.groupby(['Fruit','Name'],as_index = False).sum().pivot('Fruit','Name').fillna(0)
Name Bob Mike Steve Tom Tony

Apples 16.0 9.0 10.0 0.0 0.0
Grapes 35.0 0.0 0.0 87.0 15.0
Oranges 67.0 57.0 0.0 15.0 1.0
Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).
The 'trick' here is to use the node priority to as the vote count...
The data is:
vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote
,"vote": {
".read" : true
,".write" : true
,"$issue" : {
"user" : {
"$user" : {
".validate" : "!data.exists() &&
newData.val()==data.parent().parent().child('count').getPriority()+1 &&
newData.val()==newData.GetPriority()"
user can only vote once && count must be one higher than current count && data value must be same as priority.
}
}
,"count" : {
".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
newData.getPriority()==data.getPriority()+1 "
}
count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.
}
}
Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.
<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
window.fb = new Firebase('https:...vote/iss1/');
window.fb.child('count').once('value', function (dss) {
votes = dss.getPriority();
for (var i=1;i<10;i++) vote(dss,i+votes);
} );
function vote(dss,count)
{
var user='user/zz' + count; // replace with auth.id or whatever
window.fb.child(user).setWithPriority(count,count);
window.fb.child('count').setWithPriority(user,count);
}
</script>
The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)
The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).
It means you're passing the variable by reference.
In fact, in a declaration of a type, it means reference, just like:
int x = 42;
int& y = x;
declares a reference to x
, called y
.
var $iframe = document.getElementByID('myIfreme');
var childDocument = iframe.contentDocument ? iframe.contentDocument : iframe.contentWindow.document;
childDocument.documentElement.scrollTop = 0;
var filePath = context.Server.MapPath(Convert.ToString(ConfigurationManager.AppSettings["ErrorLogFile"]));
var file = new FileInfo(filePath);
file.Directory.Create();
If the directory already exists, this method does nothing.
var sw = new StreamWriter(filePath, true);
sw.WriteLine(Enter your message here);
sw.Close();

Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long
and is separate from the int
type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int
type has been dropped completely.
That's just an implementation detail, though — as long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.
You can find all the gory details in PEP 0237.
Due to my subversion state, I had to get creative. svn st
showed M
,A
and ~
statuses. I only wanted M
and A
so...
svn st | grep ^[A\|M] | cut -d' ' -f8- > targets.txt
This command says find all the lines output by svn st
that start with M
or A
, cut using space delimiter, then get colums 8 to the end. Dump that into targets.txt and overwrite.
Then modify targets.txt to prune the file list further. Then run below to commit:
svn ci -m "My commit message" --targets targets.txt
Probably not the most common use case, but hopefully it helps someone.
I understand/hope that the lists have the same length: No, your only bet is going with a plain old standard for loop.

Ok guys it can be done easy in photoshop.
Open png photo and then check image -> mode value(i had indexed color). Go image -> mode and check rgb color. Now change your color EASY.
These are the droids you're looking for. This is taken from validator.js which is the library you should really use to do this. But if you want to roll your own, who am I to stop you? If you want pure regex then you can just take out the length check. I think it's a good idea to test the length of the URL though if you really want to determine compliance with the spec.
function isURL(str) {
var urlRegex = '^(?!mailto:)(?:(?:http|https|ftp)://)(?:\\S+(?::\\S*)?@)?(?:(?:(?:[1-9]\\d?|1\\d\\d|2[01]\\d|22[0-3])(?:\\.(?:1?\\d{1,2}|2[0-4]\\d|25[0-5])){2}(?:\\.(?:[0-9]\\d?|1\\d\\d|2[0-4]\\d|25[0-4]))|(?:(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)(?:\\.(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)*(?:\\.(?:[a-z\\u00a1-\\uffff]{2,})))|localhost)(?::\\d{2,5})?(?:(/|\\?|#)[^\\s]*)?$';
var url = new RegExp(urlRegex, 'i');
return str.length < 2083 && url.test(str);

From Dockerfile reference:
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.The
ENV
instruction sets the environment variable<key>
to the value<value>
.
The environment variables set usingENV
will persist when a container is run from the resulting image.
So if you need build-time customization, ARG
is your best choice.
If you need run-time customization (to run the same image with different settings), ENV
is well-suited.
If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable
Given the number of combinations involved, using ENV
to set those features at runtime is best here.
But you can combine both by:
ARG
ARG
as an ENV
That is, with a Dockerfile including:
ARG var
ENV var=${var}
You can then either build an image with a specific var
value at build-time (docker build --build-arg var=xxx
), or run a container with a specific runtime value (docker run -e var=yyy
)
The question is tagged WPF but the answers so far are specific WinForms and Win32.
To do this in WPF, simply construct a KeyEventArgs and call RaiseEvent on the target. For example, to send an Insert key KeyDown event to the currently focused element:
var key = Key.Insert; // Key to send
var target = Keyboard.FocusedElement; // Target element
var routedEvent = Keyboard.KeyDownEvent; // Event to send
target.RaiseEvent(
new KeyEventArgs(
Keyboard.PrimaryDevice,
PresentationSource.FromVisual(target),
0,
key)
{ RoutedEvent=routedEvent }
);
This solution doesn't rely on native calls or Windows internals and should be much more reliable than the others. It also allows you to simulate a keypress on a specific element.
Note that this code is only applicable to PreviewKeyDown, KeyDown, PreviewKeyUp, and KeyUp events. If you want to send TextInput events you'll do this instead:
var text = "Hello";
var target = Keyboard.FocusedElement;
var routedEvent = TextCompositionManager.TextInputEvent;
target.RaiseEvent(
new TextCompositionEventArgs(
InputManager.Current.PrimaryKeyboardDevice,
new TextComposition(InputManager.Current, target, text))
{ RoutedEvent = routedEvent }
);
Also note that:
Controls expect to receive Preview events, for example PreviewKeyDown should precede KeyDown
Using target.RaiseEvent(...) sends the event directly to the target without meta-processing such as accelerators, text composition and IME. This is normally what you want. On the other hand, if you really do what to simulate actual keyboard keys for some reason, you would use InputManager.ProcessInput() instead.
I created a new device. Deleted the previous one.
The solution proposed by @smileyborg is almost perfect. If you have a custom cell and you want one or more UILabel
with dynamic heights then the systemLayoutSizeFittingSize method combined with AutoLayout enabled returns a CGSizeZero
unless you move all your cell constraints from the cell to its contentView (as suggested by @TomSwift here How to resize superview to fit all subviews with autolayout?).
To do so you need to insert the following code in your custom UITableViewCell implementation (thanks to @Adrian).
- (void)awakeFromNib{
[super awakeFromNib];
for (NSLayoutConstraint *cellConstraint in self.constraints) {
[self removeConstraint:cellConstraint];
id firstItem = cellConstraint.firstItem == self ? self.contentView : cellConstraint.firstItem;
id seccondItem = cellConstraint.secondItem == self ? self.contentView : cellConstraint.secondItem;
NSLayoutConstraint *contentViewConstraint =
[NSLayoutConstraint constraintWithItem:firstItem
attribute:cellConstraint.firstAttribute
relatedBy:cellConstraint.relation
toItem:seccondItem
attribute:cellConstraint.secondAttribute
multiplier:cellConstraint.multiplier
constant:cellConstraint.constant];
[self.contentView addConstraint:contentViewConstraint];
}
}
Mixing @smileyborg answer with this should works.
Atom has a built-in line ending selector package
More details here: https://github.com/atom/line-ending-selector
One other point that I didn't see anyone make:
If you don't do anything in your catch {} block, having a try...catch is pointless. I see this all the time:
try
{
//Code here
}
catch
{
throw;
}
Or worse:
try
{
//Code here
}
catch(Exception ex)
{
throw ex;
}
Worst yet:
try
{
//Code here
}
catch(Exception ex)
{
throw new System.Exception(ex.Message);
}
For iOS you need to use the touchmove event as well as the scroll event like this:
document.addEventListener("touchmove", ScrollStart, false);
document.addEventListener("scroll", Scroll, false);
function ScrollStart() {
//start of scroll event for iOS
}
function Scroll() {
//end of scroll event for iOS
//and
//start/end of scroll event for other browsers
}
I created a function:
CREATE FUNCTION [dbo].[fnPadLeft](@int int, @Length tinyint)
RETURNS varchar(255)
AS
BEGIN
DECLARE @strInt varchar(255)
SET @strInt = CAST(@int as varchar(255))
RETURN (REPLICATE('0', (@Length - LEN(@strInt))) + @strInt);
END;
Use: select dbo.fnPadLeft(123, 10)
Returns: 0000000123
terrific answer from DuckPuncher, for Python3 make sure you install pdfminer2 and do:
import io
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
def convert_pdf_to_txt(path):
rsrcmgr = PDFResourceManager()
retstr = io.StringIO()
codec = 'utf-8'
laparams = LAParams()
device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
fp = open(path, 'rb')
interpreter = PDFPageInterpreter(rsrcmgr, device)
password = ""
maxpages = 0
caching = True
pagenos = set()
for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,
password=password,
caching=caching,
check_extractable=True):
interpreter.process_page(page)
fp.close()
device.close()
text = retstr.getvalue()
retstr.close()
return text
One way is to use a script tag to import the variables you want to your views:
<script type="text/javascript">
window.base_url = <?php echo json_encode(base_url()); ?>;
</script>
Here, I wrapped the base_url with json_encode so that it'll automatically escape any characters to valid Javascript. I put base_url to the global Window so you can use it anywhere just by calling base_url, but make sure to put the script tag above any Javascript that calls it. With your given example:
...
$('#style_color').attr("href", base_url + "assets/css/themes/" + color_ + ".css");
I finally found the answer for 2019. You need to add 'IIS APPPOOL\DefaultAppPool' to the list of users that have security rights to the directory that is to be modified. Make sure they have full rights.
In the collapse package recently released on CRAN, I have attempted to compress most of the common apply functionality into just 2 functions:
dapply
(Data-Apply) applies functions to rows or (default) columns of matrices and data.frames and (default) returns an object of the same type and with the same attributes (unless the result of each computation is atomic and drop = TRUE
). The performance is comparable to lapply
for data.frame columns, and about 2x faster than apply
for matrix rows or columns. Parallelism is available via mclapply
(only for MAC). Syntax:
dapply(X, FUN, ..., MARGIN = 2, parallel = FALSE, mc.cores = 1L,
return = c("same", "matrix", "data.frame"), drop = TRUE)
Examples:
# Apply to columns:
dapply(mtcars, log)
dapply(mtcars, sum)
dapply(mtcars, quantile)
# Apply to rows:
dapply(mtcars, sum, MARGIN = 1)
dapply(mtcars, quantile, MARGIN = 1)
# Return as matrix:
dapply(mtcars, quantile, return = "matrix")
dapply(mtcars, quantile, MARGIN = 1, return = "matrix")
# Same for matrices ...
BY
is a S3 generic for split-apply-combine computing with vector, matrix and data.frame method. It is significantly faster than tapply
, by
and aggregate
(an also faster than plyr
, on large data dplyr
is faster though). Syntax:
BY(X, g, FUN, ..., use.g.names = TRUE, sort = TRUE,
expand.wide = FALSE, parallel = FALSE, mc.cores = 1L,
return = c("same", "matrix", "data.frame", "list"))
Examples:
# Vectors:
BY(iris$Sepal.Length, iris$Species, sum)
BY(iris$Sepal.Length, iris$Species, quantile)
BY(iris$Sepal.Length, iris$Species, quantile, expand.wide = TRUE) # This returns a matrix
# Data.frames
BY(iris[-5], iris$Species, sum)
BY(iris[-5], iris$Species, quantile)
BY(iris[-5], iris$Species, quantile, expand.wide = TRUE) # This returns a wider data.frame
BY(iris[-5], iris$Species, quantile, return = "matrix") # This returns a matrix
# Same for matrices ...
Lists of grouping variables can also be supplied to g
.
Talking about performance: A main goal of collapse is to foster high-performance programming in R and to move beyond split-apply-combine alltogether. For this purpose the package has a full set of C++ based fast generic functions: fmean
, fmedian
, fmode
, fsum
, fprod
, fsd
, fvar
, fmin
, fmax
, ffirst
, flast
, fNobs
, fNdistinct
, fscale
, fbetween
, fwithin
, fHDbetween
, fHDwithin
, flag
, fdiff
and fgrowth
. They perform grouped computations in a single pass through the data (i.e. no splitting and recombining).
Syntax:
fFUN(x, g = NULL, [w = NULL,] TRA = NULL, [na.rm = TRUE,] use.g.names = TRUE, drop = TRUE)
Examples:
v <- iris$Sepal.Length
f <- iris$Species
# Vectors
fmean(v) # mean
fmean(v, f) # grouped mean
fsd(v, f) # grouped standard deviation
fsd(v, f, TRA = "/") # grouped scaling
fscale(v, f) # grouped standardizing (scaling and centering)
fwithin(v, f) # grouped demeaning
w <- abs(rnorm(nrow(iris)))
fmean(v, w = w) # Weighted mean
fmean(v, f, w) # Weighted grouped mean
fsd(v, f, w) # Weighted grouped standard-deviation
fsd(v, f, w, "/") # Weighted grouped scaling
fscale(v, f, w) # Weighted grouped standardizing
fwithin(v, f, w) # Weighted grouped demeaning
# Same using data.frames...
fmean(iris[-5], f) # grouped mean
fscale(iris[-5], f) # grouped standardizing
fwithin(iris[-5], f) # grouped demeaning
# Same with matrices ...
In the package vignettes I provide benchmarks. Programming with the fast functions is significantly faster than programming with dplyr or data.table, especially on smaller data, but also on large data.
This was very helpful. Angular doesn't work exactly like JQuery. It has its own jsonp() method, which indeed requires "&callback=JSON_CALLBACK" at the end of the query string. Here's an example:
var librivoxSearch = angular.module('librivoxSearch', []);
librivoxSearch.controller('librivoxSearchController', function ($scope, $http) {
$http.jsonp('http://librivox.org/api/feed/audiobooks/author/Melville?format=jsonp&callback=JSON_CALLBACK').success(function (data) {
$scope.data = data;
});
});
Then display or manipulate {{ data }} in your Angular template.
q = input("Apple")
w = input("Ball")
Definition = {'apple': q, 'ball': w}
Pretty late, but you can also do this by annotating a @BeforeStep method:
@BeforeStep
public void beforeStep(final StepExecution stepExecution) {
JobParameters parameters = stepExecution.getJobExecution().getJobParameters();
//use your parameters
}
Another easy way to generate a self signed certificate is to use Jexus Manager,

File mode, write and binary. Since you are writing a .jpg file, it looks fine.
But if you supposed to read that jpg file you need to use 'rb'
More info
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.
After getting the element as jQuery object via other means than its class, then
var className = $('#sidebar div:eq(14)').attr('class');
should do the trick. For the ID use .attr('id')
.
If you are inside an event handler or other jQuery method, where the element is the pure DOM node without wrapper, you can use:
this.className // for classes, and
this.id // for IDs
Both are standard DOM methods and well supported in all browsers.

Take any web application whether it is Gmail or Facebook or Instagram or any other web application, it's all about exchanging data or information between the end user and the application or the UI and the back end application. Even in Spring MVC world there are two ways to exchange data:
What we are interested here is how the data is communicated from the UI to Controller. This can also be done in 2 ways:
Using an HTML Form: Consider the below scenario,
When we submit the form data from the web browser, we can access that data in our Controller class as an object. When we submit an HTML form, the Spring Container does four things. It will,
To get this whole thing to work, we'll have to follow certain steps.
We first need to define a model class, like User, in which the number of fields should exactly match the number of fields in the HTML form. Also, the names that we use in the HTML form should match the names that we have in the Java class. These two are very important. Names should match, the number of fields in the form should match the number of fields in the class that we create. Once we do that, the Container will automatically read the data that comes in, creates an object of this model, sets the values and it hands it over to the Controller. To read those values inside the Controller, we use the @ModelAttribute annotation on the method parameters. When we create methods in the Controller, we are going to use the @ModelAttribute and add a parameter to it which will automatically have this object given by the Container.
Here is an example code for registering an user:
@RequestMapping(value = "registerUser", method = RequestMethod.POST)
public String registerUser(@ModelAttribute("user") User user, ModelMap model) {
model.addAttribute("user", user);
return "regResult";
}
Hope this diagrammatic explanation helped!
You must use the column names and then set the values to insert (both ? marks):
//insert 1st row
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting);
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();
To achieve what you are looking for you can use the viewport-percentage length vw
.
Here is a quick example I made on jsfiddle.
HTML:
<div class="square">
<h1>This is a Square</h1>
</div>
CSS:
.square {
background: #000;
width: 50vw;
height: 50vw;
}
.square h1 {
color: #fff;
}
I am sure there are many other ways to do this but this way seemed the best to me.
Not currently. If you look at the source code (from this point in time Oct 2012), you'll see that the call to XHR open is actually hard-coded to be asynchronous (the third parameter is true):
xhr.open(method, url, true);
You'd need to write your own service that did synchronous calls. Generally that's not something you'll usually want to do because of the nature of JavaScript execution you'll end up blocking everything else.
... but.. if blocking everything else is actually desired, maybe you should look into promises and the $q service. It allows you to wait until a set of asynchronous actions are done, and then execute something once they're all complete. I don't know what your use case is, but that might be worth a look.
Outside of that, if you're going to roll your own, more information about how to make synchronous and asynchronous ajax calls can be found here.
I hope that is helpful.
EDIT: As of 2019, e.metaKey
is supported on all major browsers as per the MDN.
Note that on Windows, although the ? Windows key is considered to be the "meta" key, it is not going to be captured by browsers as such.
This is only for the command key on MacOS/keyboards.
Unlike Shift/Alt/Ctrl, the Cmd (“Apple”) key is not considered a modifier key—instead, you should listen on keydown
/keyup
and record when a key is pressed and then depressed based on event.keyCode
.
Unfortunately, these key codes are browser-dependent:

I found the solution to the problem of serializing entities was as follows:
#config/config.yml
services:
serializer.method:
class: Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer
serializer.encoder.json:
class: Symfony\Component\Serializer\Encoder\JsonEncoder
serializer:
class: Symfony\Component\Serializer\Serializer
arguments:
- [@serializer.method]
- {json: @serializer.encoder.json }
in my controller:
$serializer = $this->get('serializer');
$entity = $this->get('doctrine')
->getRepository('myBundle:Entity')
->findOneBy($params);
$collection = $this->get('doctrine')
->getRepository('myBundle:Entity')
->findBy($params);
$toEncode = array(
'response' => array(
'entity' => $serializer->normalize($entity),
'entities' => $serializer->normalize($collection)
),
);
return new Response(json_encode($toEncode));
other example:
$serializer = $this->get('serializer');
$collection = $this->get('doctrine')
->getRepository('myBundle:Entity')
->findBy($params);
$json = $serializer->serialize($collection, 'json');
return new Response($json);
you can even configure it to deserialize arrays in http://api.symfony.com/2.0
I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.
int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
for(int i=0; i<=names.size()-1; ++i) {
if(names[i]==req_name){
cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
return 0;
}
else if(names[i]!=req_name && i==names.size()-1) {
cout<<"That name is not an element in this vector"<<'\n';
} else {
continue;
}
}
The best solution in C#/all static .NET languages is to use the CodeDOM for such things. (As a note, its other main purpose is for dynamically constructing bits of code, or even whole classes.)
Here's a nice short example take from LukeH's blog, which uses some LINQ too just for fun.
using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.CSharp;
using System.CodeDom.Compiler;
class Program
{
static void Main(string[] args)
{
var csc = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } });
var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll" }, "foo.exe", true);
parameters.GenerateExecutable = true;
CompilerResults results = csc.CompileAssemblyFromSource(parameters,
@"using System.Linq;
class Program {
public static void Main(string[] args) {
var q = from i in Enumerable.Range(1,100)
where i % 2 == 0
select i;
}
}");
results.Errors.Cast<CompilerError>().ToList().ForEach(error => Console.WriteLine(error.ErrorText));
}
}
The class of primary importance here is the CSharpCodeProvider
which utilises the compiler to compile code on the fly. If you want to then run the code, you just need to use a bit of reflection to dynamically load the assembly and execute it.
Here is another example in C# that (although slightly less concise) additionally shows you precisely how to run the runtime-compiled code using the System.Reflection
namespace.
I have found using the jQuery .val() method to have a significant drawback.
<select id="gate"></select>
$("#gate").val("Gateway 2");
If this select box (or any other input object) is in a form and there is a reset button used in the form, when the reset button is clicked the set value will get cleared and not reset to the beginning value as you would expect.
This seems to work the best for me.
For Select boxes
<select id="gate"></select>
$("#gate option[value='Gateway 2']").attr("selected", true);
For text inputs
<input type="text" id="gate" />
$("#gate").attr("value", "your desired value")
For textarea inputs
<textarea id="gate"></textarea>
$("#gate").html("your desired value")
For checkbox boxes
<input type="checkbox" id="gate" />
$("#gate option[value='Gateway 2']").attr("checked", true);
For radio buttons
<input type="radio" id="gate" value="this"/> or <input type="radio" id="gate" value="that"/>
$("#gate[value='this']").attr("checked", true);
SELECT CONVERT(VARCHAR(10), GETDATE(), 105) + ' ' + CONVERT(VARCHAR(10), GETDATE(), 108)

Of course you could write a program that monitors the clipboard and displays an annoying SaveAs-dialog for every image in the clipboard ;-). I guess you can even find out if the last key pressed was PrintScreen to limit the number of false positives.
While I'm thinking about it.. you could also google for someone who already did exactly that.

Actually, the "Checkout to specific local branch"
from Claus's answer isn't needed as well.
You can just do changes, execute git commit -am "message"
and then use "Git Publisher" with "Branch to push" = /refs/heads/master
(or develop or whatever branch you need to push to), "Target remote name" = origin.
I resolved this problem by separating my content into two tables.
One table is the header row.
The seconds is also <table>
tag, but wrapped by <div>
with static height and overflow scroll.
In light of apparent dislike for how I've attempted to answer the OP's question. The literal answer is, a promise is something shared w/ other objects, while a deferred should be kept private. Primarily, a deferred (which generally extends Promise) can resolve itself, while a promise might not be able to do so.
If you're interested in the minutiae, then examine Promises/A+.
So far as I'm aware, the overarching purpose is to improve clarity and loosen coupling through a standardized interface. See suggested reading from @jfriend00:
Rather than directly passing callbacks to functions, something which can lead to tightly coupled interfaces, using promises allows one to separate concerns for code that is synchronous or asynchronous.
Personally, I've found deferred especially useful when dealing with e.g. templates that are populated by asynchronous requests, loading scripts that have networks of dependencies, and providing user feedback to form data in a non-blocking manner.
Indeed, compare the pure callback form of doing something after loading CodeMirror in JS mode asynchronously (apologies, I've not used jQuery in a while):
/* assume getScript has signature like: function (path, callback, context)
and listens to onload && onreadystatechange */
$(function () {
getScript('path/to/CodeMirror', getJSMode);
// onreadystate is not reliable for callback args.
function getJSMode() {
getScript('path/to/CodeMirror/mode/javascript/javascript.js',
ourAwesomeScript);
};
function ourAwesomeScript() {
console.log("CodeMirror is awesome, but I'm too impatient.");
};
});
To the promises formulated version (again, apologies, I'm not up to date on jQuery):
/* Assume getScript returns a promise object */
$(function () {
$.when(
getScript('path/to/CodeMirror'),
getScript('path/to/CodeMirror/mode/javascript/javascript.js')
).then(function () {
console.log("CodeMirror is awesome, but I'm too impatient.");
});
});
Apologies for the semi-pseudo code, but I hope it makes the core idea somewhat clear. Basically, by returning a standardized promise, you can pass the promise around, thus allowing for more clear grouping.
Short answer: AngularJS ("jqlite") doesn't support this. Include jQuery on your page (before including Angular), and it should work. See https://groups.google.com/d/topic/angular/H4haaMePJU0/discussion
Just loop...
foreach(var table in DataSet1.Tables) {
foreach(var col in table.Columns) {
...
}
foreach(var row in table.Rows) {
object[] values = row.ItemArray;
...
}
}
Chaining is cool, why dismiss it?
Anyway, here is another option in one replace:
string.replace(/#|_/g,function(match) {return (match=="#")?"":" ";})
The replace will choose "" if match=="#", " " if not.
[Update] For a more generic solution, you could store your replacement strings in an object:
var replaceChars={ "#":"" , "_":" " };
string.replace(/#|_/g,function(match) {return replaceChars[match];})
About the removal of componentWillReceiveProps
: you should be able to handle its uses with a combination of getDerivedStateFromProps
and componentDidUpdate
, see the React blog post for example migrations. And yes, the object returned by getDerivedStateFromProps
updates the state similarly to an object passed to setState
.
In case you really need the old value of a prop, you can always cache it in your state with something like this:
state = {
cachedSomeProp: null
// ... rest of initial state
};
static getDerivedStateFromProps(nextProps, prevState) {
// do things with nextProps.someProp and prevState.cachedSomeProp
return {
cachedSomeProp: nextProps.someProp,
// ... other derived state properties
};
}
Anything that doesn't affect the state can be put in componentDidUpdate
, and there's even a getSnapshotBeforeUpdate
for very low-level stuff.
UPDATE: To get a feel for the new (and old) lifecycle methods, the react-lifecycle-visualizer package may be helpful.

You can use the Enum::valueOf()

It sounds like you might need to create and query linked database servers in SQL Server
At the moment you've created a query that's going between different databases using a 3 part name mydatabase.dbo.mytable
but you need to go up a level and use a 4 part name myserver.mydatabase.dbo.mytable
, see this post on four part naming for more info
edit
The four part naming for your existing query would be as shown below (which I suspect you may have already tried?), but this assumes you can "get to" the remote database with the four part name, you might need to edit your host file / register the server or otherwise identify where to find database.windows.net
.
INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
([InvoiceNumber]
,[TotalAmount]
,[IsActive]
,[CreatedBy]
,[UpdatedBy]
,[CreatedDate]
,[UpdatedDate]
,[Remarks])
SELECT [InvoiceNumber]
,[TotalAmount]
,[IsActive]
,[CreatedBy]
,[UpdatedBy]
,[CreatedDate]
,[UpdatedDate]
,[Remarks] FROM [BC1-PC].[testdabse].[dbo].[invoice]
If you can't access the remote server then see if you can create a linked database server:
EXEC sp_addlinkedserver [database.windows.net];
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR
[database.windows.net].basecampdev.dbo.invoice;
GO
Then you can just query against MyEmployee
without needing the full four part name
The trick is to add environment variables to sudoers
file via sudo visudo
command and add these lines:
Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"
taken from ArchLinux wiki.
For Ubuntu 14, you need to specify in separate lines as it returns the errors for multi-variable lines:
Defaults env_keep += "http_proxy"
Defaults env_keep += "https_proxy"
Defaults env_keep += "HTTP_PROXY"
Defaults env_keep += "HTTPS_PROXY"
The EOF
character recognized by the command interpreter on Windows (and MSDOS, and CP/M) is 0x1a (decimal 26, aka Ctrl+Z aka SUB)
It can still be be used today for example to mark the end of a human-readable header in a binary file: if the file begins with "Some description\x1a"
the user can dump the file content to the console using the TYPE
command and the dump will stop at the EOF
character, i.e. print Some description and stop, instead of continuing with the garbage that follows.
MSDN says:
This delegate is used by the Array.ForEach method and the List.ForEach method to perform an action on each element of the array or list.
Except that, you can use it as a generic delegate that takes 1-3 parameters without returning any value.
I haven't tested this on a 500 code, but it works on others like 200, 302 and 404.
response=$(curl --write-out '%{http_code}' --silent --output /dev/null servername)
Note, format provided for --write-out should be quoted.
As suggested by @ibai, add --head
to make a HEAD only request. This will save time when the retrieval is successful since the page contents won't be transmitted.
Depending on the library you are using the standard GNU C Predefined Mathematical Constants are here... https://www.gnu.org/software/libc/manual/html_node/Mathematical-Constants.html
You already have them so why redefine them? Your system desktop calculators probably have them and are even more accurate so you could but just be sure you're not conflicting with existing defined ones to save on compile warnings as they tend to get defaults for things like that. Enjoy!
Here is a simple example to get the selected value of dropdown in javascript
First we design the UI for dropdown
<div class="col-xs-12">
<select class="form-control" id="language">
<option>---SELECT---</option>
<option>JAVA</option>
<option>C</option>
<option>C++</option>
<option>PERL</option>
</select>
Next we need to write script to get the selected item
<script type="text/javascript">
$(document).ready(function () {
$('#language').change(function () {
var doc = document.getElementById("language");
alert("You selected " + doc.options[doc.selectedIndex].value);
});
});
Now When change the dropdown the selected item will be alert.

Assuming your page is available under "http://example.com"

driver = webdriver.Firefox()
driver.get("http://example.com")
Select element by id:
inputElement = driver.find_element_by_id("a1")

Now you can simulate hitting ENTER:
inputElement.send_keys(Keys.ENTER)
or if it is a form you can submit:
inputElement.submit()

Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:
defaults write NSGlobalDomain KeyRepeat -int 0
Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.
You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.

.Text
gives you a string representing what is displayed on the screen for the cell. Using .Text is usually a bad idea because you could get ####
.Value2
gives you the underlying value of the cell (could be empty, string, error, number (double) or boolean)
.Value
gives you the same as .Value2 except if the cell was formatted as currency or date it gives you a VBA currency (which may truncate decimal places) or VBA date.
Using .Value or .Text is usually a bad idea because you may not get the real value from the cell, and they are slower than .Value2

H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
- Small file size for longer recording time and better network transmission.
- Fluent and better video quality for real time playback
- More efficient mobile surveillance applicationH264 is now enshrined in MPEG4 as part 10 also known as AVC
Refer to: http://www.velleman.eu/downloads/3/h264_vs_mpeg4_en.pdf

The comparator should be only for the key, not for the whole entry. It sorts the entries based on the keys.
You should change it to something as follows
SortedMap<String, Double> myMap =
new TreeMap<String, Double>(new Comparator<String>()
{
public int compare(String o1, String o2)
{
return o1.compareTo(o2);
}
});
Update
You can do something as follows (create a list of entries in the map and sort the list base on value, but note this not going to sort the map itself) -
List<Map.Entry<String, Double>> entryList = new ArrayList<Map.Entry<String, Double>>(myMap.entrySet());
Collections.sort(entryList, new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Entry<String, Double> o1, Entry<String, Double> o2) {
return o1.getValue().compareTo(o2.getValue());
}
});

First of all, a caveat. Why do you want to use telnet? telnet is an old protocol, unsafe and impractical for remote access. It's been (almost)totally replaced by ssh.
To answer your questions, it depends. It depends on the telnet client you use. If you use microsoft telnet, you can't. Microsoft telnet does not have any mean to send commands from a batch file or a command line.

In your program you would have opened the connections and left open without closing it.
I faced a same problem and finally identified.
I added this code, after try catch.
finally{
try {
rs.close();
p.close();
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Here dataTpe is "json" so, data/reqParam must be in the form of string while calling API, many as much as object as you want but at last inside $.ajax's data stringify the object.
let person= { name: 'john',
age: 22
};
var personStr = JSON.stringify(person);
$.ajax({
url: "@Url.Action("METHOD", "CONTROLLER")",
type: "POST",
data: JSON.stringify( { param1: personStr } ),
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (response) {
console.log("Success");
},
error: function (error) {
console.log("error found",error);
}
});
OR,
$.ajax({
url: "@Url.Action("METHOD", "CONTROLLER")",
type: "POST",
data: personStr,
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (response) {
console.log("Success");
},
error: function (error) {
console.log("error found",error);
}
});
You can do it like this using Lodash get
_.get(object, 'a[0].b.c');
To "update" the Toast message after unchecking some items, just put this line inside the for loop:
if (sp.valueAt(i))
so it results:
for(int i=0;i<sp.size();i++)
{
if (sp.valueAt(i))
str+=names[sp.keyAt(i)]+",";
}
It's very much considered one of those things you Do Not Do, but was probably listed as a reserved word to avoid confusion for developers.
For the latest version, first open a Powershell window, go to any folder (e.g. c:\projects\
) and run the following
# Get nuget.exe command line
wget https://dist.nuget.org/win-x86-commandline/latest/nuget.exe -OutFile nuget.exe
# Download the C# Roslyn compiler (just a few megs, no need to 'install')
.\nuget.exe install Microsoft.Net.Compilers
# Compiler, meet code
.\Microsoft.Net.Compilers.1.3.2\tools\csc.exe .\HelloWorld.cs
# Run it
.\HelloWorld.exe
An example HelloWorld.cs
using System;
public class HelloWorld {
public static void Main()
{
Console.WriteLine("Hello world!");
}
}
You can also try the new C# interpreter ;)
.\Microsoft.Net.Compilers.1.3.2\tools\csi.exe
> Console.WriteLine("Hello world!");
Hello world!
If you are using Swift, this will do the same:
buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)
Hope that helps!
Write-back and write-through describe policies when a write hit occurs, that is when the cache has the requested information. In these examples, we assume a single processor is writing to main memory with a cache.
Write-through: The information is written to the cache and memory, and the write finishes when both have finished. This has the advantage of being simpler to implement, and the main memory is always consistent (in sync) with the cache (for the uniprocessor case - if some other device modifies main memory, then this policy is not enough), and a read miss never results in writes to main memory. The obvious disadvantage is that every write hit has to do two writes, one of which accesses slower main memory.
Write-back: The information is written to a block in the cache. The modified cache block is only written to memory when it is replaced (in effect, a lazy write). A special bit for each cache block, the dirty bit, marks whether or not the cache block has been modified while in the cache. If the dirty bit is not set, the cache block is "clean" and a write miss does not have to write the block to memory.
The advantage is that writes can occur at the speed of the cache, and if writing within the same block only one write to main memory is needed (when the previous block is being replaced). The disadvantages are that this protocol is harder to implement, main memory can be not consistent (not in sync) with the cache, and reads that result in replacement may cause writes of dirty blocks to main memory.
The policies for a write miss are detailed in my first link.
These protocols don't take care of the cases with multiple processors and multiple caches, as is common in modern processors. For this, more complicated cache coherence mechanisms are required. Write-through caches have simpler protocols since a write to the cache is immediately reflected in memory.

In Ubuntu 16.04 LTS with composer globally installed, this worked for me.
Edit the .bashrc file in your home directory puting the path to the composer bin folder that is located in /your/home/.config/composer/vendor/bin
echo 'export PATH="$PATH:$HOME/.config/composer/vendor/bin"' >> ~/.bashrc
source ~/.bashrc
If not works, verify the path to the composer bin directory and close and reopen the terminal. Otherwise, try to logoff and login in the Ubuntu.
Also works in ubuntu 18.04. Thanks @chifliiiii for your feedback.
You can use floating:

The difference between page and window with respect to WPF: Page vs Window in WPF?
From the Android Developer Site link
"adjustResize"
The activity's main window is always resized to make room for the soft keyboard on screen.
"adjustPan"
The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.
according to your comment, use following in your activity manifest
<activity android:windowSoftInputMode="adjustResize"> </activity>
From the man git-stash
page:
The modifications stashed away by this command can be listed with git stash list, inspected with git stash show
show [<stash>]
Show the changes recorded in the stash as a diff between the stashed state and
its original parent. When no <stash> is given, shows the latest one. By default,
the command shows the diffstat, but it will accept any format known to git diff
(e.g., git stash show -p stash@{1} to view the second most recent stash in patch
form).
To list the stashed modifications
git stash list
To show files changed in the last stash
git stash show
So, to view the content of the most recent stash, run
git stash show -p
To view the content of an arbitrary stash, run something like
git stash show -p stash@{1}
Here are the significant differences between lateinit var
and by lazy { ... }
delegated property:
lazy { ... }
delegate can only be used for val
properties, whereas lateinit
can only be applied to var
s, because it can't be compiled to a final
field, thus no immutability can be guaranteed;
lateinit var
has a backing field which stores the value, and by lazy { ... }
creates a delegate object in which the value is stored once calculated, stores the reference to the delegate instance in the class object and generates the getter for the property that works with the delegate instance. So if you need the backing field present in the class, use lateinit
;
In addition to val
s, lateinit
cannot be used for nullable properties or Java primitive types (this is because of null
used for uninitialized value);
lateinit var
can be initialized from anywhere the object is seen from, e.g. from inside a framework code, and multiple initialization scenarios are possible for different objects of a single class. by lazy { ... }
, in turn, defines the only initializer for the property, which can be altered only by overriding the property in a subclass. If you want your property to be initialized from outside in a way probably unknown beforehand, use lateinit
.
Initialization by lazy { ... }
is thread-safe by default and guarantees that the initializer is invoked at most once (but this can be altered by using another lazy
overload). In the case of lateinit var
, it's up to the user's code to initialize the property correctly in multi-threaded environments.
A Lazy
instance can be saved, passed around and even used for multiple properties. On contrary, lateinit var
s do not store any additional runtime state (only null
in the field for uninitialized value).
If you hold a reference to an instance of Lazy
, isInitialized()
allows you to check whether it has already been initialized (and you can obtain such instance with reflection from a delegated property). To check whether a lateinit property has been initialized, you can use property::isInitialized
since Kotlin 1.2.
A lambda passed to by lazy { ... }
may capture references from the context where it is used into its closure.. It will then store the references and release them only once the property has been initialized. This may lead to object hierarchies, such as Android activities, not being released for too long (or ever, if the property remains accessible and is never accessed), so you should be careful about what you use inside the initializer lambda.
Also, there's another way not mentioned in the question: Delegates.notNull()
, which is suitable for deferred initialization of non-null properties, including those of Java primitive types.
This is simple code to do it, I avoided all checks but this is the main idea.
public String parse(String jsonLine) {
JsonElement jelement = new JsonParser().parse(jsonLine);
JsonObject jobject = jelement.getAsJsonObject();
jobject = jobject.getAsJsonObject("data");
JsonArray jarray = jobject.getAsJsonArray("translations");
jobject = jarray.get(0).getAsJsonObject();
String result = jobject.get("translatedText").getAsString();
return result;
}
To make the use more generic - you will find that Gson's javadocs are pretty clear and helpful.
We could type our variable with an explicit return type:
const script: HTMLScriptElement = document.getElementsByName(id).item(0);
Or assert as (needed with TSX):
const script = document.getElementsByName(id).item(0) as HTMLScriptElement;
Or in simpler cases assert with angle-bracket syntax.
A type assertion is like a type cast in other languages, but performs no special checking or restructuring of data. It has no runtime impact, and is used purely by the compiler.

I just experienced this same problem with the Laravel 4 php framework which uses the guzzlehttp/guzzle
composer package. For some reason, the SSL certificate for mailgun stopped validating suddenly and I got that same "error 60" message.
If, like me, you are on a shared hosting without access to php.ini
, the other solutions are not possible. In any case, Guzzle has this client initializing code that would most likely nullify the php.ini
effects:
// vendor/guzzlehttp/guzzle/src/Client.php
$settings = [
'allow_redirects' => true,
'exceptions' => true,
'decode_content' => true,
'verify' => __DIR__ . '/cacert.pem'
];
Here Guzzle forces usage of its own internal cacert.pem file, which is probably now out of date, instead of using the one provided by cURL's environment. Changing this line (on Linux at least) configures Guzzle to use cURL's default SSL verification logic and fixed my problem:
'verify' => true
You can also set this to false
if you don't care about the security of your SSL connection, but that's not a good solution.
Since the files in vendor
are not meant to be tampered with, a better solution would be to configure the Guzzle client on usage, but this was just too difficult to do in Laravel 4.
Hope this saves someone else a couple hours of debugging...
The Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the request been a GET.
It doesn't matter what the content-type is.
Extension at post below.
XAMPP should have come with a "fake" sendmail program. In that case, you can use sendmail as well:
[mail function]
; For Win32 only.
; http://php.net/smtp
;SMTP = localhost
; http://php.net/smtp-port
;smtp_port = 25
; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = [email protected]
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "C:/xampp/sendmail/sendmail.exe -t -i"
Sendmail should have a sendmail.ini
with it; it should be configured as so:
# Example for a user configuration file
# Set default values for all following accounts.
defaults
logfile "C:\xampp\sendmail\sendmail.log"
# Mercury
#account Mercury
#host localhost
#from postmaster@localhost
#auth off
# A freemail service example
account ACCOUNTNAME_HERE
tls on
tls_certcheck off
host smtp.gmail.com
from EMAIL_HERE
auth on
user EMAIL_HERE
password PASSWORD_HERE
# Set a default account
account default : ACCOUNTNAME_HERE
Of course, replace ACCOUNTNAME_HERE with an arbitrary account name, replace EMAIL_HERE with a valid email (such as a Gmail or Hotmail), and replace PASSWORD_HERE with the password to your email. Now, you should be able to send mail. Remember to restart Apache (from the control panel or the batch files) to allow the changes to PHP to work.
The Java runtime you try to execute your program with is an earlier version than Java 7 which was the target you compile your program for.
For Ubuntu use
apt-get install openjdk-7-jdk
to get Java 7 as default. You may have to uninstall openjdk-6 first.
1) Maybe oveflow: hidden; will do the trick?
2) You need to set the size of each div with the text and button so that each of these divs have the same height. Then for your button:
button {
position: absolute;
bottom: 0;
}
I don't want to name names, but someone appears to be completely wrong. The referenced standards body stated the following: submissions 465 tcp Message Submission over TLS protocol [IESG] [IETF_Chair] 2017-12-12 [RFC8314]
If you are so inclined, you may wish to read the referenced RFC.
This seems to clearly imply that port 465 is the best way to force encrypted communication and be sure that it is in place. Port 587 offers no such guarantee.
To compare with an int do this:
<?php
$date = date("m");
$dateToCompareTo = 05;
if (strval($date) == strval($dateToCompareTo)) {
echo "They are the same";
}
?>
If you consider that the child item should be deleted when the parent is deleted, then it is an identifying relationship.
If the child item should be kept even though the parent is deleted, then it is a non-identifying relatio?ship.
As an example, I have a training database with trainees, trainings, diplomas and training sessions :
Only training sessions should be deleted if one of the related trainee, training or diploma is deleted.
I ran into this very problem trying to send mail with javax.mail from a web application in a web server running Java 7. Internal mail server destinations failed with "network unreachable", despite telnet and ping working from the same host, and while external mail servers worked. I tried
System.setProperty("java.net.preferIPv4Stack" , "true");
in the code, but that failed. So the parameter value was probably cached earlier by the system. Setting the VM argument
-Djava.net.preferIPv4Stack=true
in the web server startup script worked.
One further bit of evidence: in a very small targeted test program, setting the system property in the code did work. So the parameter is probably cached when the first Socket is used, probably not just as the JVM starts.
Searched on the go-nuts email list and found a solution posted by Peter Froehlich on 11/15/2009.
package main
import "fmt"
func main() {
dict := map[string]int {"foo" : 1, "bar" : 2}
value, ok := dict["baz"]
if ok {
fmt.Println("value: ", value)
} else {
fmt.Println("key not found")
}
}
Or, more compactly,
if value, ok := dict["baz"]; ok {
fmt.Println("value: ", value)
} else {
fmt.Println("key not found")
}
Note, using this form of the if
statement, the value
and ok
variables are only visible inside the if
conditions.
window.document.onkeydown = function(){};
Another way to do this is:
// inflate the layout
View myLayout = LayoutInflater.from(this).inflate(R.layout.MY_LAYOUT,null);
// load the text view
TextView myView = (TextView) myLayout.findViewById(R.id.MY_VIEW);
Here's another solution using df.transform
and df.set_index
:
>>> (df['teams']
.transform([lambda x:x[0], lambda x:x[1]])
.set_axis(['team1','team2'],
axis=1,
inplace=False)
)
team1 team2
0 SF NYG
1 SF NYG
2 SF NYG
3 SF NYG
4 SF NYG
5 SF NYG
6 SF NYG
I go with
HttpContext.Current.Request.ServerVariables["HTTP_HOST"]
If you read a string from an XML file, the line break \n
in this string will not work in UILabel
text. The \n
is not parsed to a line break.
Here is a little trick to solve this issue:
// correct next line \n in string from XML file
NSString *myNewLineStr = @"\n";
myLabelText = [myLabelText stringByReplacingOccurrencesOfString:@"\\n" withString:myNewLineStr];
myLabel.text = myLabelText;
So you have to replace the unparsed \n
part in your string by a parsed \n
in a hardcoded NSString
.
Here are my other label settings:
myLabel.numberOfLines = 0;
myLabel.backgroundColor = [UIColor lightGrayColor];
myLabel.textColor = [UIColor redColor];
myLabel.font = [UIFont fontWithName:@"Helvetica Neue" size:14.0];
myLabel.textAlignment = UITextAlignmentCenter;
Most important is to set numberOfLines
to 0
(= unlimited number of lines in label).
No idea why Apple has chosen to not parse \n
in strings read from XML?
Hope this helps.
Edit If you are asking about security, see my addendum at the bottom Edit
PHP has a serialize function provided for this specific purpose. Pass it an array, and it will give you a string representation of it. When you want to convert it back to an array, you just use the unserialize function.
$data = array('one'=>1, 'two'=>2, 'three'=>33);
$dataString = serialize($data);
//send elsewhere
$data = unserialize($dataString);
This is often used by lazy coders to save data to a database. Not recommended, but works as a quick/dirty solution.
Addendum
I was under the impression that you were looking for a way to send the data reliably, not "securely". No matter how you pass the data, if it is going through the users system, you cannot trust it at all. Generally, you should store it somewhere on the server & use a credential (cookie, session, password, etc) to look it up.
CSS (or jQuery, for that matter) can't animate between display: none;
and display: block;
. Worse yet: it can't animate between height: 0
and height: auto
. So you need to hard code the height (if you can't hard code the values then you need to use javascript, but this is an entirely different question);
#main-image{
height: 0;
overflow: hidden;
background: red;
-prefix-animation: slide 1s ease 3.5s forwards;
}
@-prefix-keyframes slide {
from {height: 0;}
to {height: 300px;}
}
You mention that you're using Animate.css, which I'm not familiar with, so this is a vanilla CSS.
You can see a demo here: http://jsfiddle.net/duopixel/qD5XX/
I moved workbench.xmi located at workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi to a backup folder. Then started eclipse and waited for all background processes to finish. Then I closed eclipse and moved my backup copy of workbench.xmi back (overwriting the one created with the last launch). Eclipse launched fine and I got all my settings back.

In Microsoft C/C++, you can use the built-in _CRT_STRINGIZE()
to print constants. Many of my stdafx.h
files contain some combination of these:
#pragma message("_MSC_VER is " _CRT_STRINGIZE(_MSC_VER))
#pragma message("_MFC_VER is " _CRT_STRINGIZE(_MFC_VER))
#pragma message("_ATL_VER is " _CRT_STRINGIZE(_ATL_VER))
#pragma message("WINVER is " _CRT_STRINGIZE(WINVER))
#pragma message("_WIN32_WINNT is " _CRT_STRINGIZE(_WIN32_WINNT))
#pragma message("_WIN32_IE is " _CRT_STRINGIZE(_WIN32_IE))
#pragma message("NTDDI_VERSION is " _CRT_STRINGIZE(NTDDI_VERSION))
and outputs something like this:
_MSC_VER is 1915
_MFC_VER is 0x0E00
_ATL_VER is 0x0E00
WINVER is 0x0600
_WIN32_WINNT is 0x0600

Feel free to use the above class in your project. For example, you could give your users a selection of font families and set the typeface based on their preference.
A small incomplete example:
final List<FontListParser.SystemFont> fonts = FontListParser.safelyGetSystemFonts();
String[] items = new String[fonts.size()];
for (int i = 0; i < fonts.size(); i++) {
items[i] = fonts.get(i).name;
}
new AlertDialog.Builder(this).setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
FontListParser.SystemFont selectedFont = fonts.get(which);
// TODO: do something with the font
Toast.makeText(getApplicationContext(), selectedFont.path, Toast.LENGTH_LONG).show();
}
}).show();

"I want a Bitmap d, that is grayscale. I do see a consructor that includes System.Drawing.Imaging.PixelFormat, but I don't understand how to use that."
Here is how to do this
Bitmap grayScaleBP = new
System.Drawing.Bitmap(2, 2, System.Drawing.Imaging.PixelFormat.Format16bppGrayScale);
EDIT: To convert to grayscale
Bitmap c = new Bitmap("fromFile");
Bitmap d;
int x, y;
// Loop through the images pixels to reset color.
for (x = 0; x < c.Width; x++)
{
for (y = 0; y < c.Height; y++)
{
Color pixelColor = c.GetPixel(x, y);
Color newColor = Color.FromArgb(pixelColor.R, 0, 0);
c.SetPixel(x, y, newColor); // Now greyscale
}
}
d = c; // d is grayscale version of c
