There is a download for the Google API Python Client library that contains the library and all of its dependencies, named something like google-api-python-client-gae-<version>.zip in the downloads section of the project. Just unzip this into your App Engine project.
Instead of installing the bloated IIS, I get mine resolved by installing Internet Information Services Hostable Web Core from the Windows Features
All the answers are pointing to a Lambda expression with an NRE (Null Reference Exception). I have found that it also occurs when using Linq to Entities. I thought it would be helpful to point out that this exception is not limited to just an NRE inside a Lambda expression.
This must be the world's most generic error message because I got it today on the following command using Excel Interop:
Excel.WorkbookConnection conn;
conn.ODBCConnection.Connection = "DSN=myserver;";
What fixed it was specifying ODBC in the connection string:
conn.ODBCConnection.Connection = "ODBC;DSN=myserver;";
On the off chance anyone else has this error, I hope it helps.
You see the two empty -D
entries in the g++
command line? They're causing the problem. You must have values in the -D
items e.g. -DWIN32
if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:
SYSTEM ?= generic
ENVIRONMENT ?= generic
in the makefile which gives them default values.
Your output looks to be missing the all important output:
<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers
just to clarify, what actually got sent to g++
was -D -DWindows_NT
, i.e. define a preprocessor macro called -DWindows_NT
; which is of course not a valid identifier (similarly for -D -I.
)
I Think this is because of IIS is unable to find the root folder. i.e wwwroot. Restarting the IIS wont be helpful in some scenarios. if the root path has changed, you should bring it back to %SystemDrive%\inetpub\wwwroot
by right clicking sites node in IIS and changing physical path to the above one.
and make sure that your application pool is asp.net v4.0 and running in integrated mode

Note that both of these example are NOT extension methods like the example above.
Lastly... apologies for my extensive/excessive comments (I had a anal/mean prof that beat it into me! ;)
Just wanted to clarify this for myself, while using the new reflection API based on TypeInfo
- where BindingFlags
is not available reliably (depending on target framework).
In the 'new' reflection, to get the static properties for a type (not including base class(es)) you have to do something like:
IEnumerable<PropertyInfo> props =
type.GetTypeInfo().DeclaredProperties.Where(p =>
(p.GetMethod != null && p.GetMethod.IsStatic) ||
(p.SetMethod != null && p.SetMethod.IsStatic));
Caters for both read-only or write-only properties (despite write-only being a terrible idea).
The DeclaredProperties
member, too doesn't distinguish between properties with public/private accessors - so to filter around visibility, you then need to do it based on the accessor you need to use. E.g - assuming the above call has returned, you could do:
var publicStaticReadable = props.Where(p => p.GetMethod != null && p.GetMethod.IsPublic);
There are some shortcut methods available - but ultimately we're all going to be writing a lot more extension methods around the TypeInfo
query methods/properties in the future. Also, the new API forces us to think about exactly what we think of as a 'private' or 'public' property from now on - because we must filter ourselves based on individual accessors.
Could you not just have a different Draw method for each type that you want to Draw? Then call the overloaded Draw method passing in the object of type itemType to be drawn.
Your question does not make it clear whether itemType genuinely refers to objects of differing types.
In addition mysql passwords when not using the IDENTIFIED BY
clause, may be blank values, if non-blank, they may be encrypted. But yes USAGE
is used to modify an account by granting simple resource limiters such as MAX_QUERIES_PER_HOUR
, again this can be specified by also
using the WITH clause, in conjuction with GRANT USAGE
(no privileges added) or GRANT ALL
, you can also specify GRANT USAGE
at the global level, database level, table level,etc....
It is worth noting that @Marius's second answer could be used as pure Javascript solution.

I think you need str.contains
, if you need rows where values of column date
contains string 07311954
:
print df[df['date'].astype(str).str.contains('07311954')]
Or if type
of date
column is string
:
print df[df['date'].str.contains('07311954')]
If you want check last 4 digits for string
1954
in column date
:
print df[df['date'].astype(str).str[-4:].str.contains('1954')]
Sample:
print df['date']

Look at the traceback:
Traceback (most recent call last):
File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
out = iter(out)
TypeError: 'bool' object is not iterable
Your code isn't iterating the value, but the code receiving it is.
The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)
) or enclose it in a tuple ((False,)
).
Always read the traceback: it's correct, and it's helpful.

The modern equivalent of goto
(arguable, only my opinion, etc) is explicit exception handling:
Edited to highlight the code reuse better.
Pretend pseudocode in a fake python-like language with goto
:
def myfunc1(x)
if x == 0:
goto LABEL1
return 1/x
def myfunc2(z)
if z == 0:
goto LABEL1
return 1/z
myfunc1(0)
myfunc2(0)
:LABEL1
print 'Cannot divide by zero'.
Compared to python:
def myfunc1(x):
return 1/x
def myfunc2(y):
return 1/y
try:
myfunc1(0)
myfunc2(0)
except ZeroDivisionError:
print 'Cannot divide by zero'
Explicit named exceptions are a significantly better way to deal with non-linear conditional branching.
I have used frames at my continuing education commercial site for over 15 years. Frames allow the navigation frame to load material into the main frame using the target feature while leaving the navigator frame untouched. Furthermore, Perl scripts operate quite well from a frame form returning the output to the same frame. I love frames and will continue using them. CSS is far too complicated for practical use. I have had no problems using frames with HTML5 with IE, Safari, Chrome, or Firefox.
The answer from dhams is correct (after having been edited several times), but as the many edits of the code shows, it is difficult to write correct and robust code for deleting a directory (with sub-dirs) yourself. So I strongly suggest using Apache Commons IO, or some other API that does this for you:
import org.apache.commons.io.FileUtils;
...
// Delete local cache dir (ignoring any errors):
FileUtils.deleteQuietly(context.getCacheDir());
PS: Also delete the directory returned by context.getExternalCacheDir() if you use that.
To be able to use Apache Commons IO, add this to your build.gradle
file, in the dependencies
part:
compile 'commons-io:commons-io:2.4'
==
and !=
do not take into account the data type of the variables you compare. So these would all return true:
'0' == 0
false == 0
NULL == false
===
and !==
do take into account the data type. That means comparing a string to a boolean will never be true because they're of different types for example. These will all return false:
'0' === 0
false === 0
NULL === false
You should compare data types for functions that return values that could possibly be of ambiguous truthy/falsy value. A well-known example is strpos()
:
// This returns 0 because F exists as the first character, but as my above example,
// 0 could mean false, so using == or != would return an incorrect result
var_dump(strpos('Foo', 'F') != false); // bool(false)
var_dump(strpos('Foo', 'F') !== false); // bool(true), it exists so false isn't returned
What if you specified the default value to return, instead of using default(T)?
public static T GetQueryString<T>(string key, T defaultValue) {...}
It makes calling it easier too:
var intValue = GetQueryString("intParm", Int32.MinValue);
var strValue = GetQueryString("strParm", "");
var dtmValue = GetQueryString("dtmPatm", DateTime.Now); // eg use today's date if not specified
The downside being you need magic values to denote invalid/missing querystring values.
UPDATE TABLE
SET EndDate = CAST('2017-12-31' AS DATE)
WHERE Id = '123'
Assuming not null longVal
Integer intVal = ((Number)longVal).intValue();
It works for example y you get an Object that can be an Integer or a Long. I know that is ugly, but it happens...
Simplest way:
>>> from datetime import datetime
>>> dt = datetime(2008, 1, 1, 0, 0, 0, 0)
>>> dt.strftime("%s")
'1199163600'
Edit: @Daniel is correct, this would convert it to the machine's timezone. Here is a revised answer:
>>> from datetime import datetime, timezone
>>> epoch = datetime(1970, 1, 1, 0, 0, 0, 0, timezone.utc)
>>> dt = datetime(2008, 1, 1, 0, 0, 0, 0, timezone.utc)
>>> int((dt-epoch).total_seconds())
'1199145600'
In fact, its not even necessary to specify timezone.utc
, because the time difference is the same so long as both datetime
have the same timezone (or no timezone).
>>> from datetime import datetime
>>> epoch = datetime(1970, 1, 1, 0, 0, 0, 0)
>>> dt = datetime(2008, 1, 1, 0, 0, 0, 0)
>>> int((dt-epoch).total_seconds())
1199145600
Convert your x-axis data from text to datetime.datetime
, use datetime.strptime
:
>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
datetime.datetime(2012, 5, 31, 19, 0)
This is an example of how to plot data once you have an array of datetimes:
import matplotlib.pyplot as plt
import datetime
import numpy as np
x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)
plt.plot(x,y)
plt.show()
The problem is your dataType
and the format of your data
parameter. I just tested this in a sandbox and the following works:
C#
[HttpPost]
public string ConvertLogInfoToXml(string jsonOfLog)
{
return Convert.ToString(jsonOfLog);
}
javascript
<input type="button" onclick="test()"/>
<script type="text/javascript">
function test() {
data = { prop: 1, myArray: [1, "two", 3] };
//'data' is much more complicated in my real application
var jsonOfLog = JSON.stringify(data);
$.ajax({
type: 'POST',
dataType: 'text',
url: "Home/ConvertLogInfoToXml",
data: "jsonOfLog=" + jsonOfLog,
success: function (returnPayload) {
console && console.log("request succeeded");
},
error: function (xhr, ajaxOptions, thrownError) {
console && console.log("request failed");
},
processData: false,
async: false
});
}
</script>
Pay special attention to data
, when sending text, you need to send a variable that matches the name of your parameter. It's not pretty, but it will get you your coveted unformatted string.
When running this, jsonOfLog looks like this in the server function:
jsonOfLog "{\"prop\":1,\"myArray\":[1,\"two\",3]}" string

Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.
Gantt chart for this ques will be:

This line:
[self dismissViewControllerAnimated:YES completion:nil];
isn't sending a message to itself, it's actually sending a message to its presenting VC, asking it to do the dismissing. When you present a VC, you create a relationship between the presenting VC and the presented one. So you should not destroy the presenting VC while it is presenting (the presented VC can't send that dismiss message back…). As you're not really taking account of it you are leaving the app in a confused state. See my answer Dismissing a Presented View Controller in which I recommend this method is more clearly written:
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil];
In your case, you need to ensure that all of the controlling is done in mainVC
. You should use a delegate to send the correct message back to MainViewController from ViewController1, so that mainVC can dismiss VC1 and then present VC2.
In VC2 VC1 add a protocol in your .h file above the @interface:
@protocol ViewController1Protocol <NSObject>
- (void)dismissAndPresentVC2;
@end
and lower down in the same file in the @interface section declare a property to hold the delegate pointer:
@property (nonatomic,weak) id <ViewController1Protocol> delegate;
In the VC1 .m file, the dismiss button method should call the delegate method
- (IBAction)buttonPressedFromVC1:(UIButton *)sender {
[self.delegate dissmissAndPresentVC2]
}
Now in mainVC, set it as VC1's delegate when creating VC1:
- (IBAction)present1:(id)sender {
ViewController1* vc = [[ViewController1 alloc] initWithNibName:@"ViewController1" bundle:nil];
vc.delegate = self;
[self present:vc];
}
and implement the delegate method:
- (void)dismissAndPresent2 {
[self dismissViewControllerAnimated:NO completion:^{
[self present2:nil];
}];
}
present2:
can be the same method as your VC2Pressed:
button IBAction method. Note that it is called from the completion block to ensure that VC2 is not presented until VC1 is fully dismissed.
You are now moving from VC1->VCMain->VC2 so you will probably want only one of the transitions to be animated.
update
In your comments you express surprise at the complexity required to achieve a seemingly simple thing. I assure you, this delegation pattern is so central to much of Objective-C and Cocoa, and this example is about the most simple you can get, that you really should make the effort to get comfortable with it.
In Apple's View Controller Programming Guide they have this to say:
Dismissing a Presented View Controller
When it comes time to dismiss a presented view controller, the preferred approach is to let the presenting view controller dismiss it. In other words, whenever possible, the same view controller that presented the view controller should also take responsibility for dismissing it. Although there are several techniques for notifying the presenting view controller that its presented view controller should be dismissed, the preferred technique is delegation. For more information, see “Using Delegation to Communicate with Other Controllers.”
If you really think through what you want to achieve, and how you are going about it, you will realise that messaging your MainViewController to do all of the work is the only logical way out given that you don't want to use a NavigationController. If you do use a NavController, in effect you are 'delegating', even if not explicitly, to the navController to do all of the work. There needs to be some object that keeps a central track of what's going on with your VC navigation, and you need some method of communicating with it, whatever you do.
In practice Apple's advice is a little extreme... in normal cases, you don't need to make a dedicated delegate and method, you can rely on [self presentingViewController] dismissViewControllerAnimated:
- it's when in cases like yours that you want your dismissing to have other effects on remote objects that you need to take care.
Here is something you could imagine to work without all the delegate hassle...
- (IBAction)dismiss:(id)sender {
[[self presentingViewController] dismissViewControllerAnimated:YES
completion:^{
[self.presentingViewController performSelector:@selector(presentVC2:)
withObject:nil];
}];
}
After asking the presenting controller to dismiss us, we have a completion block which calls a method in the presentingViewController to invoke VC2. No delegate needed. (A big selling point of blocks is that they reduce the need for delegates in these circumstances). However in this case there are a few things getting in the way...
present2
- you can end up with difficult-to-debug errors or crashes. Delegates help you to avoid this.So please... take the time to learn delegation!
update2
In your comment you have managed to make it work by using this in VC2's dismiss button handler:
[self.view.window.rootViewController dismissViewControllerAnimated:YES completion:nil];
This is certainly much simpler, but it leaves you with a number of issues.
Tight coupling
You are hard-wiring your viewController structure together. For example, if you were to insert a new viewController before mainVC, your required behaviour would break (you would navigate to the prior one). In VC1 you have also had to #import VC2. Therefore you have quite a lot of inter-dependencies, which breaks OOP/MVC objectives.
Using delegates, neither VC1 nor VC2 need to know anything about mainVC or it's antecedents so we keep everything loosely-coupled and modular.
Memory
VC1 has not gone away, you still hold two pointers to it:
presentedViewController
propertypresentingViewController
propertyYou can test this by logging, and also just by doing this from VC2
[self dismissViewControllerAnimated:YES completion:nil];
It still works, still gets you back to VC1.
That seems to me like a memory leak.
The clue to this is in the warning you are getting here:
[self presentViewController:vc2 animated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];
// Attempt to dismiss from view controller <VC1: 0x715e460>
// while a presentation or dismiss is in progress!
The logic breaks down, as you are attempting to dismiss the presenting VC of which VC2 is the presented VC. The second message doesn't really get executed - well perhaps some stuff happens, but you are still left with two pointers to an object you thought you had got rid of. (edit - I've checked this and it's not so bad, both objects do go away when you get back to mainVC)
That's a rather long-winded way of saying - please, use delegates. If it helps, I made another brief description of the pattern here:
Is passing a controller in a construtor always a bad practice?
update 3
If you really want to avoid delegates, this could be the best way out:
In VC1:
[self presentViewController:VC2
animated:YES
completion:nil];
But don't dismiss anything... as we ascertained, it doesn't really happen anyway.
In VC2:
[self.presentingViewController.presentingViewController
dismissViewControllerAnimated:YES
completion:nil];
As we (know) we haven't dismissed VC1, we can reach back through VC1 to MainVC. MainVC dismisses VC1. Because VC1 has gone, it's presented VC2 goes with it, so you are back at MainVC in a clean state.
It's still highly coupled, as VC1 needs to know about VC2, and VC2 needs to know that it was arrived at via MainVC->VC1, but it's the best you're going to get without a bit of explicit delegation.

Something has deleted your ibdata1 file where InnoDB keeps the dictionary. Definitely it's not MySQL who does it.
UPDATE: I made a tutorial on how to fix the error - https://youtu.be/014KbCYayuE
Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:
"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage
which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh
"thought" that it is run in the regular terminal and since it may be accomplished by simple posix
functions, it is beyond what simple bash
offers.
I know that it's posible to pass references of pointers, I did it last week, but I can't remember what the syntax was, as your code looks correct to my brain right now. However another option is to use pointers of pointers:
Myfunc(String** s)
I am using this from PowerShell:

HTML4 specification states that:
Inline elements may contain only data and other inline elements
Span is an inline element, therefore having span inside span is valid. There's a related question: Can <span> tags have any type of tags inside them? which makes it completely clear.
HTML5 specification (including the most current draft of HTML 5.3 dated November 16, 2017) changes terminology, but it's still perfectly valid to place span inside another span.

[Context] In a virtual machine of WinXP.
My "java.exe" was in the Oracle11g folder, under the path "C:\Oracle11g\product\11.2.0\dbhome_1\jdk\bin\java.exe".
Hope it helps!!
I guess to some degree it's a DBA vs. developer issue.
As a dev mostly, I'd say don't use it unless you absolutely positively have to - because using it can break your ADO.NET code (as documented by Microsoft).
And I guess as a DBA, you'd be more on the other side - use it whenever possible unless you really must prevent it's usage.
Also, if your devs ever use the "RecordsAffected" being returned by ADO.NET's ExecuteNonQuery
method call, you're in trouble if everyone uses SET NOCOUNT ON
since in this case, ExecuteNonQuery will always return 0.
Also see Peter Bromberg's blog post and check out his position.
So it really boils down to who gets to set the standards :-)

Multiple backgrounds!
body {_x000D_
background: #eb01a5;_x000D_
background-image: url("IMAGE_URL"); /* fallback */_x000D_
background-image: url("IMAGE_URL"), linear-gradient(#eb01a5, #d13531); /* W3C */_x000D_
}
_x000D_
These 2 lines are the fallback for any browser that doesn't do gradients. See notes for stacking images only IE < 9 below.
The final line sets a background image and gradient for browsers that can handle them.
Nearly all current browsers have support for multiple background images and css backgrounds. See http://caniuse.com/#feat=css-gradients for browser support. For a good post on why you don't need multiple browser prefixes, see http://codepen.io/thebabydino/full/pjxVWp/
Layer Stack
It should be noted that the first defined image will be topmost in the stack. In this case, the image is on TOP of the gradient.
For more information about background layering see http://www.w3.org/TR/css3-background/#layering.
Stacking images ONLY (no gradients in the declaration) For IE < 9
IE9 and up can stack images this same way. You could use this to create a gradient image for ie9, though personally, I wouldn't. However to be noted when using only images, ie < 9 will ignore the fallback statement and not show any image. This does not happen when a gradient is included. To use a single fallback image in this case I suggest using Paul Irish's wonderful Conditional HTML element along with your fallback code:
.lte9 #target{ background-image: url("IMAGE_URL"); }
Background position, sizing etc.
Other properties that would apply to a single image may also be comma separated. If only 1 value is supplied, that will be applied to all stacked images including the gradient. background-size: 40px;
will constrain both the image and the gradient to 40px height and width. However using background-size: 40px, cover;
will make the image 40px and the gradient will cover the element. To only apply a setting to one image, set the default for the other: background-position: 50%, 0 0;
or for browsers that support it use initial
: background-position: 50%, initial;
You may also use the background shorthand, however this removes the fallback color and image.
body{
background: url("IMAGE_URL") no-repeat left top, linear-gradient(#eb01a5, #d13531);
}
The same applies to background-position, background-repeat, etc.
You should specify
<input type="checkbox" name="Days[]" value="Daily">Daily<br>
as array.
Add []
to all names Days
and work at php with this like an array.
After it, you can INSERT
values at different columns at db, or use implode
and save values into one column.
Didn't tested it, but you can try like this. Don't forget to replace mysql
with mysqli
.
<html>
<body>
<form method="post" action="chk123.php">
Flights on: <br/>
<input type="checkbox" name="Days[]" value="Daily">Daily<br>
<input type="checkbox" name="Days[]" value="Sunday">Sunday<br>
<input type="checkbox" name="Days[]" value="Monday">Monday<br>
<input type="checkbox" name="Days[]" value="Tuesday">Tuesday <br>
<input type="checkbox" name="Days[]" value="Wednesday">Wednesday<br>
<input type="checkbox" name="Days[]" value="Thursday">Thursday <br>
<input type="checkbox" name="Days[]" value="Friday">Friday<br>
<input type="checkbox" name="Days[]" value="Saturday">Saturday <br>
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>
<?php
// Make a MySQL Connection
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());
$checkBox = implode(',', $_POST['Days']);
if(isset($_POST['submit']))
{
$query="INSERT INTO example (orange) VALUES ('" . $checkBox . "')";
mysql_query($query) or die (mysql_error() );
echo "Complete";
}
?>
Using Following Code You Solve thisQuestion.... If you run a file using localhost server than this problem solve by following Jsp Page Code.This Code put Between Head Tag in jsp file
<style type="text/css">
<%@include file="css/style.css" %>
</style>
<script type="text/javascript">
<%@include file="js/script.js" %>

Actually the correct answer to this is to just add the schema to your document, like so
<packages xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
...and you're done :)
If the XSD is not already cached and unavailable, you can add it as follows from the NuGet console
Install-Package NuGet.Manifest.Schema -Version 2.0.0
Once this is done, as noted in a comment below, you may want to move it from your current folder to the official schema folder that is found in
%VisualStudioPath%\Xml\Schemas
if [ $var1 != $var2 ]
then
echo "$var1"
else
echo "$var2"
fi
pip show <package name>
will provide the location for Windows and macOS, and I'm guessing any system. :)
For example:
> pip show cvxopt
Name: cvxopt
Version: 1.2.0
...
Location: /usr/local/lib/python2.7/site-packages
Why not use a generator instead?
private IEnumerable<string> ReadLogLines(string logPath) {
using(StreamReader reader = File.OpenText(logPath)) {
string line = "";
while((line = reader.ReadLine()) != null) {
yield return line;
}
}
}
Then you can use it like you would use the list:
var logFile = ReadLogLines(LOG_PATH);
foreach(var s in logFile) {
// Do whatever you need
}
Of course, if you need to have a List<string>
, then you will need to keep the entire file contents in memory. There's really no way around that.
I created my own Gem, but I did it in a directory that is not in my load path:
$ pwd
/Users/myuser/projects
$ gem build my_gem/my_gem.gemspec
Then I ran irb
and tried to load the Gem:
> require 'my_gem'
LoadError: cannot load such file -- my_gem
I used the global variable $: to inspect my load path and I realized I am using RVM. And rvm has specific directories in my load path $:
. None of those directories included my ~/projects directory where I created the custom gem.
So one solution is to modify the load path itself:
$: << "/Users/myuser/projects/my_gem/lib"
Note that the lib directory is in the path, which holds the my_gem.rb file which will be required in irb:
> require 'my_gem'
=> true
Now if you want to install the gem in RVM path, then you would need to run:
$ gem install my_gem
But it will need to be in a repository like rubygems.org.
$ gem push my_gem-0.0.0.gem
Pushing gem to RubyGems.org...
Successfully registered gem my_gem
You can try "request.get_full_path()"
If your HTML is well-formed, you can easily employ an XML parser to do the job for you... If you're only reading, SAX would be ideal.
$scope.clearSearch = function () {
$scope.searchAll = "";
};
JsFiddle of how you could do it without using inline JS.
As said already in the comments you can use the csv
library in python. csv means comma separated values which seems exactly your case: a label and a value separated by a comma.
Being a category and value type I would rather use a dictionary type instead of a list of tuples.
Anyway in the code below I show both ways: d
is the dictionary and l
is the list of tuples.
import csv
file_name = "test.txt"
try:
csvfile = open(file_name, 'rt')
except:
print("File not found")
csvReader = csv.reader(csvfile, delimiter=",")
d = dict()
l = list()
for row in csvReader:
d[row[1]] = row[0]
l.append((row[0], row[1]))
print(d)
print(l)
You can also change the name attribute of your form elements to be something generated so that the browser won't keep track of it. HOWEVER firefox 2.x+ and google chrome seems to not have much problems with that if the request url is identical. Try basically adding a salt request param and a salt field name for the sign-up form.
However I think autocomplete="off" is still top solution :)
For is()
import static org.hamcrest.CoreMatchers.*;
For assertThat()

For when() and verify()

Please change
con = (HttpURLConnection) new URL("http://localhost:8080/myapp/service/generate").openConnection();

The simplest answer is add the ref="some name" in the input text element and call the below function.
componentDidMount(){
this.refs.field_name.focus();
}
// here field_name is ref name.
<input type="text" ref="field_name" />
This had no effect for me:
public void changeTheme(int newTheme) {
setTheme(newTheme);
recreate();
}
But this worked:
int theme = R.style.default;
protected void onCreate(Bundle savedInstanceState) {
setTheme(this.theme);
super.onCreate(savedInstanceState);
}
public void changeTheme(int newTheme) {
this.theme = newTheme;
recreate();
}
eaccelerator could be causing the problem since it compiles PHP into blocks...I've had this problem with an Amazon AWS server on a site with heavy load. Free up Inodes by deleting the eaccelerator cache in /var/cache/eaccelerator if you continue to have issues.
rm -rf /var/cache/eaccelerator/*
(or whatever your cache dir)

Model
public class Book
{
public string Title {get;set;}
public string Author {get;set;}
}
Controller
public class BookController : Controller
{
[HttpPost]
public ActionResult Create(Book model, IEnumerable<HttpPostedFileBase> fileUpload)
{
throw new NotImplementedException();
}
}
And View
@using (Html.BeginForm("Create", "Book", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.EditorFor(m => m)
<input type="file" name="fileUpload[0]" /><br />
<input type="file" name="fileUpload[1]" /><br />
<input type="file" name="fileUpload[2]" /><br />
<input type="submit" name="Submit" id="SubmitMultiply" value="Upload" />
}
Note title of parameter from controller action must match with name of input elements
IEnumerable<HttpPostedFileBase> fileUpload
-> name="fileUpload[0]"
fileUpload
must match
I've an object (basically a VO) in Java and I don't know its type. I need to get values which are not null in that object.
Maybe you don't necessary need reflection for that -- here is a plain OO design that might solve your problem:
Validation
which expose a method validate
which checks the fields and return whatever is appropriate. Validation
and check that easily.I guess that you need the field that are null to display an error message in a generic way, so that should be enough. Let me know if this doesn't work for you for some reason.
The following key combinations are used to do things:
CTRL + M + M → Collapse / Expand current preset area (e.g. Method)
CTRL + M + H → Collapse / Hide (Expand) current selection
CTRL + M + O → Collapse all(Collapse declaration bodies)
CTRL + M + A → Collapse all
CTRL + M + X → Expand all
CTRL + M + L → Toggle all
There some options in the context menu under Outlining.
You can also use Windows PowerShell with the following command:
if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
[System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
}
Make sure to check that the source does not exist before calling CreateEventSource, otherwise it will throw an exception.

In my case, I was getting this error because I had an input named x
and I was creating (without realizing it) a local variable called x
. I thought I was trying to access an element of the input x
(which was an array), while I was actually trying to access an element of the local variable x
(which was a scalar).
I use following to clear session and clear aspnet_sessionID
:
HttpContext.Current.Session.Clear();
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));

Why perform the summation forwards when you can do it backwards? Given:
std::vector<int> v; // vector to be summed
int sum_of_elements(0); // result of the summation
We can use subscripting, counting backwards:
for (int i(v.size()); i > 0; --i)
sum_of_elements += v[i-1];
We can use range-checked "subscripting," counting backwards (just in case):
for (int i(v.size()); i > 0; --i)
sum_of_elements += v.at(i-1);
We can use reverse iterators in a for loop:
for(std::vector<int>::const_reverse_iterator i(v.rbegin()); i != v.rend(); ++i)
sum_of_elements += *i;
We can use forward iterators, iterating backwards, in a for loop (oooh, tricky!):
for(std::vector<int>::const_iterator i(v.end()); i != v.begin(); --i)
sum_of_elements += *(i - 1);
We can use accumulate
with reverse iterators:
sum_of_elems = std::accumulate(v.rbegin(), v.rend(), 0);
We can use for_each
with a lambda expression using reverse iterators:
std::for_each(v.rbegin(), v.rend(), [&](int n) { sum_of_elements += n; });
So, as you can see, there are just as many ways to sum the vector backwards as there are to sum the vector forwards, and some of these are much more exciting and offer far greater opportunity for off-by-one errors.
for w64-based computers you have to install mingw64. If pkg-config.exe is missing then, you can refer to http://ftp.acc.umu.se/pub/gnome/binaries/win64/dependencies/
Unzip and copy/merge pkg-config.exe into your C:\mingw-w64 installation, eg. into on my pc into C:\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin
To return a value from a VBScript function, assign the value to the name of the function, like this:
Function getNumber
getNumber = "423"

This is from the Docker documentation itself, might be of help, simple and plain:
"The host directory is, by its nature, host-dependent. For this reason, you can’t mount a host directory from Dockerfile, the VOLUME instruction does not support passing a host-dir, because built images should be portable. A host directory wouldn’t be available on all potential hosts.".

I haven't used either, but I was going to at one point and they seemed like they should work.
I presume that this question is a continuation of this one.
What are you trying to do? Do you really want to dynamically change the text in your TextView objects when the user clicks a button? You can certainly do that, if you have a reason, but, if the text is static, it is usually set in the main.xml file, like this:
<TextView
android:id="@+id/rate"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/rate"
/>
The string "@string/rate" refers to an entry in your strings.xml file that looks like this:
<string name="rate">Rate</string>
If you really want to change this text later, you can do so by using Nikolay's example - you'd get a reference to the TextView by utilizing the id defined for it within main.xml, like this:
final TextView textViewToChange = (TextView) findViewById(R.id.rate);
textViewToChange.setText(
"The new text that I'd like to display now that the user has pushed a button.");
Try this: Left-click the tab, making a copy of the whole sheet, then cut the cells you want to keep the same and paste them into your original worksheet.
maybe you need to set your window-size dimension. just like:
options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--window-size=1920x1080');
browser = webdriver.Chrome(options=options,executable_path = './chromedriver')
if also not working, try increase window-size dimension.
What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.
You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

If you only need to find a free port for later use, here is a snippet similar to a previous answer, but shorter, using socketserver:
import socketserver
with socketserver.TCPServer(("localhost", 0), None) as s:
free_port = s.server_address[1]
Note that the port is not guaranteed to remain free, so you may need to put this snippet and the code using it in a loop.
Bash is a Command Line Interface that was created over twenty-seven years ago by Brian Fox as a free software replacement for the Bourne Shell. A shell is a specific kind of Command Line Interface. Bash is "open source" which means that anyone can read the code and suggest changes. Since its beginning, it has been supported by a large community of engineers who have worked to make it an incredible tool. Bash is the default shell for Linux and Mac. For these reasons, Bash is the most used and widely distributed shell.
Windows has a different Command Line Interface, called Command Prompt. While this has many of the same features as Bash, Bash is much more popular. Because of the strength of the open source community and the tools they provide, mastering Bash is a better investment than mastering Command Prompt.
To use Bash on a Windows computer, we need to download and install a program called Git Bash. Git Bash (Is the Bash for windows) allows us to easily access Bash as well as another tool called Git, inside the Windows environment.
du
is handy, but find
is useful in case if you want to calculate the size of some files only (for example, using filter by extension). Also note that find
themselves can print the size of each file in bytes. To calculate a total size we can connect dc
command in the following manner:
find . -type f -printf "%s + " | dc -e0 -f- -ep
Here find
generates sequence of commands for dc
like 123 + 456 + 11 +
.
Although, the completed program should be like 0 123 + 456 + 11 + p
(remember postfix notation).
So, to get the completed program we need to put 0
on the stack before executing the sequence from stdin, and print the top number after executing (the p
command at the end).
We achieve it via dc
options:
-e0
is just shortcut for -e '0'
that puts 0
on the stack,-f-
is for read and execute commands from stdin (that generated by find
here),-ep
is for print the result (-e 'p'
).To print the size in MiB like 284.06 MiB
we can use -e '2 k 1024 / 1024 / n [ MiB] p'
in point 3 instead (most spaces are optional).
There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.
When you define your list as:
List myList = new ArrayList();
you can only call methods and reference members that are defined in the List interface. If you define it as:
ArrayList myList = new ArrayList();
you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.
Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).
That's called polymorphism. You can read up on it.

Create a PowerShell script with the following code in the file.
param([string]$path)
Get-ChildItem $path | Where-Object {$_.LinkType -eq 'SymbolicLink'} | select name, target
This creates a script with a path parameter. It will list all symbolic links within the path provided as well as the specified target of the symbolic link.
If you want a timestamp instead of just a date with sysdate, you can specify a timezone using systimestamp:
select systimestamp at time zone 'UTC' from dual
outputs: 29-AUG-17 06.51.14.781998000 PM UTC
For character processing, use Unicode strings:
PythonWin 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AMD64)] on win32.
>>> s='ABC??def'
>>> import re
>>> re.sub(r'[^\x00-\x7f]',r' ',s) # Each char is a Unicode codepoint.
'ABC def'
>>> b = s.encode('utf8')
>>> re.sub(rb'[^\x00-\x7f]',rb' ',b) # Each char is a 3-byte UTF-8 sequence.
b'ABC def'
But note you will still have a problem if your string contains decomposed Unicode characters (separate character and combining accent marks, for example):
>>> s = 'mañana'
>>> len(s)
6
>>> import unicodedata as ud
>>> n=ud.normalize('NFD',s)
>>> n
'man~ana'
>>> len(n)
7
>>> re.sub(r'[^\x00-\x7f]',r' ',s) # single codepoint
'ma ana'
>>> re.sub(r'[^\x00-\x7f]',r' ',n) # only combining mark replaced
'man ana'
It looks to me like it's because you are instantiating your TabListener every time... so the system is recreating your fragment from the savedInstanceState and then you are doing it again in your onCreate.
You should wrap that in a if(savedInstanceState == null)
so it only fires if there is no savedInstanceState.
You do not have serial
package installed.
Try pip install serial
to install the module.
Alternatively, install it in binary form from here:
Note that you always install precompiled binaries at your own risk.
The first recursive call moves all the pieces except the biggest one from source to by using dest as the auxilary pile. When done all the pieces except the biggest will lie on by and the biggest one is free. Now you can move the biggest one to dest and use another recursive call to move all the pieces from by to dest.
The recursive calls won't know anything about the biggest piece (i.e. they will ignore it), but that's ok because the recursive calls will only deal with the pieces that are smaller and thus can be moved onto and off the biggest piece freely.
This works for me:
adb shell dumpsys activity
And this to show current activity name:
adb shell dumpsys activity activities | grep mFocusedActivity | cut -d . -f 5 | cut -d ' ' -f 1
Well, you're on the right path, Benno!
There are some tips regarding VBA programming that might help you out.
Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.
As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.
Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.
Now, let's have a draft code...
Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.
Hope it helps!
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oSheet As Excel.Worksheet
'We only want to do something if the changed cell is B6, right?
If Target.Address = "$B$6" Then
'Checks if it's a number...
If IsNumeric(Target.Value) Then
'Let's avoid values out of your bonds, correct?
If Target.Value > 0 And Target.Value < 51 Then
'Let's assign the worksheet we'll show / hide rows to one variable and then
' use only the reference to the variable itself instead of the sheet name.
' It's safer.
'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
' the sheet index within the workbook
Set oSheet = ActiveWorkbook.Sheets("Sheet 2")
'We'll unhide before hide, to ensure we hide the correct ones
oSheet.Range("A7:A56").EntireRow.Hidden = False
oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True
End If
End If
End If
End Sub
The object, method, and property names in the .NET language bindings do not exactly correspond to those in the Java bindings. One of the principles of the project is that each language binding should "feel natural" to those comfortable coding in that language. In C#, the code you'd want for executing JavaScript is as follows
IWebDriver driver; // assume assigned elsewhere
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("return document.title");
Note that the complete documentation of the WebDriver API for .NET can be found at this link.

An excellent 2014 IBM research paper “An Updated Performance Comparison of Virtual Machines and Linux Containers” by Felter et al. provides a comparison between bare metal, KVM, and Docker containers. The general result is: Docker is nearly identical to native performance and faster than KVM in every category.
The exception to this is Docker’s NAT — if you use port mapping (e.g., docker run -p 8080:8080
), then you can expect a minor hit in latency, as shown below. However, you can now use the host network stack (e.g., docker run --net=host
) when launching a Docker container, which will perform identically to the Native column (as shown in the Redis latency results lower down).
They also ran latency tests on a few specific services, such as Redis. You can see that above 20 client threads, highest latency overhead goes Docker NAT, then KVM, then a rough tie between Docker host/native.
Just because it’s a really useful paper, here are some other figures. Please download it for full access.
Taking a look at Disk I/O:
Now looking at CPU overhead:
Now some examples of memory (read the paper for details, memory can be extra tricky):
You want to put it in the very beginning, before return type. But most Compilers ignore it. If it's defined, and it has a smaller block of code, most compilers consider it inline anyway.
Not sure anyone is still interested, but this information was posted about Twitter (and here too):

For converting date to string check this thread
Convert java.util.Date to String
And for converting string to date try this,
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class StringToDate
{
public static void main(String[] args) throws ParseException
{
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
String strDate = "14/03/2003 08:05:10";
System.out.println("Date - " + sdf.parse(strDate));

It could be solved by re.search()
import re
url = 'https://docs.google.com/spreadsheet/ccc?key=blah-blah-blah-blah#gid=1'

.sort()
, in pymongo, takes key
and direction
as parameters.
So if you want to sort by, let's say, id
then you should .sort("_id", 1)
For multiple fields:
.sort([("field1", pymongo.ASCENDING), ("field2", pymongo.DESCENDING)])
You can use the minDate
property, like this:
$("input.DateFrom").datepicker({
changeMonth: true,
changeYear: true,
dateFormat: 'yy-mm-dd',
minDate: 0, // 0 days offset = today
maxDate: 'today',
onSelect: function(dateText) {
$sD = new Date(dateText);
$("input#DateTo").datepicker('option', 'minDate', min);
}
});
You can also specify a date, like this:
minDate: new Date(), // = today
Swift 4 solution
Three simple steps:
Change the constraints, e.g.:
heightAnchor.constant = 50
Tell the containing view
that its layout is dirty and that the autolayout should recalculate the layout:
self.view.setNeedsLayout()
In animation block tell the layout to recalculate the layout, which is equivalent of setting the frames directly (in this case the autolayout will set the frames):
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
Complete simplest example:
heightAnchor.constant = 50
self.view.setNeedsLayout()
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
Sidenote
There is an optional 0th step - before changing the constraints you might want to call self.view.layoutIfNeeded()
to make sure that the starting point for the animation is from the state with old constraints applied (in case there were some other constraints changes that should not be included in animation):
otherConstraint.constant = 30
// this will make sure that otherConstraint won't be animated but will take effect immediately
self.view.layoutIfNeeded()
heightAnchor.constant = 50
self.view.setNeedsLayout()
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
Since with iOS 10 we got a new animating mechanism - UIViewPropertyAnimator
, we should know that basically the same mechanism applies to it. The steps are basically the same:
heightAnchor.constant = 50
self.view.setNeedsLayout()
let animator = UIViewPropertyAnimator(duration: 0.5, timingParameters: UICubicTimingParameters(animationCurve: .linear))
animator.addAnimations {
self.view.layoutIfNeeded()
}
animator.startAnimation()
Since animator
is an encapsulation of the animation, we can keep reference to it and call it later. However, since in the animation block we just tell the autolayout to recalculate the frames, we have to change the constraints before calling startAnimation
. Therefore something like this is possible:
// prepare the animator first and keep a reference to it
let animator = UIViewPropertyAnimator(duration: 0.5, timingParameters: UICubicTimingParameters(animationCurve: .linear))
animator.addAnimations {
self.view.layoutIfNeeded()
}
// at some other point in time we change the constraints and call the animator
heightAnchor.constant = 50
self.view.setNeedsLayout()
animator.startAnimation()
The order of changing constraints and starting an animator is important - if we just change the constraints and leave our animator for some later point, the next redraw cycle can invoke autolayout recalculation and the change will not be animated.
Also, remember that a single animator is non-reusable - once you run it, you cannot "rerun" it. So I guess there is not really a good reason to keep the animator around, unless we use it for controlling an interactive animation.
instead of os.walk
, just use os.listdir
Accepted answer doesn't work with "use strict" as the "with" statement throws an error. So instead:
$.post(url, function (data) {
var w = window.open('about:blank', 'windowname');
w.document.write(data);
w.document.close();
});
Also, make sure 'windowname' doesn't have any spaces in it because that will fail in IE :)
In a one to many and many to one relationship this error will occur. If you attempt to devote same instance from many to one entity to more than one instance from one to many entity.
For example, each person can have many books but each of these books can be owned by only one person if you consider more than one owner for a book this issue is raised.
A tad more generic copy/paste function for your project.
sumjq = function(selector) {
var sum = 0;
$(selector).each(function() {
sum += Number($(this).text());
});
return sum;
}
console.log(sumjq('.price'));
You were almost there : just add theme(legend.title=element_blank())
ggplot(df, aes(x, y, colour=g)) +
geom_line(stat="identity") +
theme(legend.position="bottom") +
theme(legend.title=element_blank())
This page on Cookbook for R gives plenty of details on how to customize legends.
Another simple way that's supported by all browsers would be:
HTML:
<form class="disabled">
<input type="text" name="name" />
<input type="radio" name="gender" value="male">
<input type="radio" name="gender" value="female">
<input type="checkbox" name="vegetarian">
</form>
CSS:
.disabled {
pointer-events: none;
opacity: .4;
}
But be aware, that the tabbing still works with this approach and the elements with focus can still be manipulated by the user.
You have to catch the error just as you're already doing for your save()
call and since you're handling multiple errors here, you can try
multiple calls sequentially in a single do-catch block, like so:
func deleteAccountDetail() {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
do {
let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
} catch {
print(error)
}
}
Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws
then try
to call the method. For example:
func deleteAccountDetail() throws {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
}
If you're using PDO:
$offset="+10:00";
$db->exec("SET time_zone='".$offset."';");
If you're using MySQLi:
$db->MySQLi->query("SET time_zone='".$offset."';");
More about formatting the offset here: https://www.sitepoint.com/synchronize-php-mysql-timezone-configuration/
I would rather use split()
instead of Regex for this operation:
function getUrlParams() {
var result = {};
var params = (window.location.search.split('?')[1] || '').split('&');
for(var param in params) {
if (params.hasOwnProperty(param)) {
var paramParts = params[param].split('=');
result[paramParts[0]] = decodeURIComponent(paramParts[1] || "");
}
}
return result;
}
If you want it outside of loop then use the below code.
<?php
$author_id = get_post_field ('post_author', $cause_id);
$display_name = get_the_author_meta( 'display_name' , $author_id );
echo $display_name;
?>
First of all can I just say that I really really love the Internet community for all that it does in providing answers to everybody. I don't post a lot but everybody's posting here and on so many boards helped me so much! None of them gave me the right answer mind you, but here is my unique solution to this nightmare of a spending 2 solid days trying to install MySQL 5.5.9 on Snow Leopard 10.6. Skip to bottom for resolution.
Here's what happened.
I had a server crash recently. The server was rebuilt and of course MySQL 5.5.8 didn't work. What a worthless piece. I had 5.1.54 on my other machine. That had been a pain to install as well but not like this.
I had all sorts of issues installing with the dmg from mysql.org, installing mysql5 using macports, uninstalling trying to revert to 5.1.54 (couldn't because I couldn't find the receipt file with that info even though I followed the directions). After rming everything I could find related to mysql and then reinstalling 5.5.8 everything worked! Until I rebooted... ? I looked in my system preference mysql pane and found mysql server wasn't starting. (skip to end for resolution)
My first error (super common) included: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' and numerous other EXTREMELY common issues related to mysql.sock http://forums.mysql.com/read.php?11,9689,13272
Here were things I tried: 1)Create /etc/my.cnf file with the proper paths to mysql.sock. I even tried modifying mysql.server with vi directly. Modifying the php.ini was worthless. Nothing worked because MySQL wasn't starting, therefore it wasn't creating mysql.sock in the first place. Maybe you can point to the directory it is being created, and not the actual full file path i.e. not /tmp/mysql.sock but /tmp It was suggested but wasn't working because there was no mysql.sock because mysqld wasn't spawning.
2)Basedir and datadir modifications didn't work because there was no mysql.sock to point too.
Why? Because the mysql daemon wasn't starting. Without anything to start mysqld and thereby create mysql.sock I was doomed. They are an important part of the solution but if you try them and still get errors, you will know why.
3)sudo chown -R root:wheel /Library/StartupItems/MySQLCOM/
didn't solve my problem. I ended up having that folder and all items set to root:wheel though in the end, because it was one of the many things recommended and its working. Maybe it could remain _mysql but wheel works.
4)Copy mysql.sock from another machine. Doesn't work. I had searched and searched my new machine and couldn't find mysql.sock. I was using find / | grep mysql.sock because locate mysql wasn't finding anything. Besides I was trying so many different things it wasn't updating enough to find my new installs. I now like find much more than locate, even though you can update the locate db. Anyhow you can't copy mysql.sock, even if you tar it because its a 0 byte file.
THE RESOLUTION: I finally stumbled onto the solution. I finally just typed mysqld from command line while I was in the proper bin directory. It said another process was running. _mysql was spawning a process that I could see in the Activity Monitor. I killed the active mysql process and when I typed mysqld again I found it was creating my mysql.sock file in the /private/tmp/mysql.sock
The mysql pref pane wouldn't start the right process on login, so I just disabled that for being worthless. It wouldn't start mysql because no mysql.sock was being created.
By then I had figured out that mysqld creates mysql.sock. I then found /opt/local/mysql/ and typed "open bin" in the terminal window. This opened the directory with mysqld in it.
I went to login items in the system preferences in my account settings and dragged and dropped the mysqld file onto the startup items there. THAT worked. Finally!
It works flawlessly because mysqld is starting up at login, which means mysql.sock is being created so no more errors about not being able to find mysql.sock.
The maximum number of characters that will be accepted as input. This can be greater that specified by SIZE , in which case the field will scroll appropriately. The default is unlimited.
<input type="text" maxlength="2" id="sessionNo" name="sessionNum" onkeypress="return isNumberKey(event)" />
However, this may or may not be affected by your handler. You may need to use or add another handler function to test for length, as well.
In Java 8 we can also make use of streams e.g.
String[] strings = Stream.of("First", "Second", "Third").toArray(String[]::new);
In case we already have a list of strings (stringList
) then we can collect into string array as:
String[] strings = stringList.stream().toArray(String[]::new);
To mock a static method that return void for e.g. Fileutils.forceMKdir(File file),
Sample code:
File file =PowerMockito.mock(File.class);
PowerMockito.doNothing().when(FileUtils.class,"forceMkdir",file);
It could also be a python version issue. I had to pick the right one to make it work.
Get today's date (& time) and apply them as maximum date.
Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Mounth -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());
ALSO WE MAY DO THIS (check this Stackoverflow answer for System.currentTimeMillis() vs Calendar method)
long now = System.currentTimeMillis() - 1000;
dp_time.setMinDate(now);
dp_time.setMaxDate(now+(1000*60*60*24*7)); //After 7 Days from Now
Well, you can modify the value of the counter, but that is obviously a brittle solution. You can load your content via AJAX after you have determined the site is not within a frame - also not a great solution, but it hopefully avoids firing the on beforeunload event (I am assuming).
Edit: Another idea. If you detect you are in a frame, ask the user to disable javascript, before clicking on a link that takes you to the desired URL (passing a querystring that lets your page know to tell the user that they can re-enable javascript once they are there).
Edit 2: Go nuclear - if you detect you are in a frame, just delete your document body content and print some nasty message.
Edit 3: Can you enumerate the top document and set all functions to null (even anonymous ones)?
If you'd decide for a solution acting "in place" you could take a look at this one:
>>> d = [ { 'a':'1' , 'b':'2' , 'c':'3' }, { 'd':'4' , 'e':'5' , 'f':'6' } ]
>>> [dt.update({k: int(v)}) for dt in d for k, v in dt.iteritems()]
[None, None, None, None, None, None]
>>> d
[{'a': 1, 'c': 3, 'b': 2}, {'e': 5, 'd': 4, 'f': 6}]
Btw, key order is not preserved because that's the way standard dictionaries work, ie without the concept of order.
I've fought the HTML email battle before. Here are some of my tips about styling for maximum compatibility between email clients.
Inline styles are you best friend. Absolutely don't link style sheets and do not use a <style>
tag (GMail, for example, strips that tag and all it's contents).
Against your better judgement, use and abuse tables. <div>
s just won't cut it (especially in Outlook).
Don't use background images, they're spotty and will annoy you.
Remember that some email clients will automatically transform typed out hyperlinks into links (if you don't anchor <a>
them yourself). This can sometimes achieve negative effects (say if you're putting a style on each of the hyperlinks to appear a different color).
Be careful hyperlinking an actual link with something different. For example, don't type out http://www.google.com
and then link it to https://gmail.com/
. Some clients will flag the message as Spam or Junk.
Save your images in as few colors as possible to save on size.
If possible, embed your images in your email. The email won't have to reach out to an external web server to download them and they won't appear as attachments to the email.
And lastly, test, test, test! Each email client does things way differently than a browser would do.
If this didn't work:
<ImageView
android:layout_gravity="center_horizontal"
android:paddingTop="10px"
android:paddingBottom="5px"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:src="@android:drawable/divider_horizontal_bright" />
Try this raw View:
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="#000000" />
This is because pushd is a builtin function in bash. So it is not related to the PATH variable and also it is not supported by /bin/sh (which is used by default by make. You can change that by setting SHELL (although it will not work directly (test1)).
You can instead run all the commands through bash -c "..."
. That will make the commands, including pushd/popd, run in a bash environment (test2).
SHELL = /bin/bash
test1:
@echo before
@pwd
@pushd /tmp
@echo in /tmp
@pwd
@popd
@echo after
@pwd
test2:
@/bin/bash -c "echo before;\
pwd; \
pushd /tmp; \
echo in /tmp; \
pwd; \
popd; \
echo after; \
pwd;"
When running make test1 and make test2 it gives the following:
prompt>make test1
before
/download/2011/03_mar
make: pushd: Command not found
make: *** [test1] Error 127
prompt>make test2
before
/download/2011/03_mar
/tmp /download/2011/03_mar
in /tmp
/tmp
/download/2011/03_mar
after
/download/2011/03_mar
prompt>
For test1, even though bash is used as a shell, each command/line in the rule is run by itself, so the pushd command is run in a different shell than the popd.
Maybe I am missing something (lots of many-upvotes-members answers here that seem to be looking at this different to I, which would seem implausible that I am correct), but length is not the correct terminology for counting something. Length is usually used to obtain what you are getting, and not what you are wanting.
$cars.count
should give you what you seem to be looking for.
I comment out //api 'com.google.android.gms:play-services-ads:15.0.1'
it worked for me after sync
Actually an other way to solve this could be, overwriting the CSS with insertRule
.
It gives the ability to inject CSS rules to an existing/new stylesheet. In my concrete example it would look like this:
//creates a new `style` element in the document
var sheet = (function(){
var style = document.createElement("style");
// WebKit hack :(
style.appendChild(document.createTextNode(""));
// Add the <style> element to the page
document.head.appendChild(style);
return style.sheet;
})();
//add the actual rules to it
sheet.insertRule(
"ul#mainFilter a:hover { color: #0000EE }" , 0
);

About ZeroMQ aka 0MQ, as you might already know, it's the one that will get you the most messages per seconds (they were about 4 millions per sec on their ref server last time I checked), but as you might also already know, the documentation is non existent. You will have a hard time finding how to start the server(s), let alone how to use them. I guess that's partly why no one contributed about 0MQ yet.
Have fun!
You can do your whole program in one line! Yes, that is right, one line!
Console.WriteLine(DateTime.Now.ToString("yyyy.MM.dd"));
You may notice that I did not use the same date format as you. That is because you should use the International Date Format as described in this W3C document. Every time you don't use it, somewhere a cute little animal dies.
You will need to assign an ID to the checkbox:
<input id="checkboxId" type="checkbox" checked="" name="copyNewAddrToBilling">
and then in JavaScript:
document.getElementById("checkboxId").checked = false;
Syntax:
$data = Model::whereIn('field_name', [1, 2, 3])->get();
Use for Users Model
$usersList = Users::whereIn('id', [1, 2, 3])->get();
<script>
function numberWithCommas(x) {
return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
</script>
Use:
numberWithCommas(200000);
==> 200,000
No application written in 2017 (or thereafter) that intends to incorporate serious cryptography should use RSA any more. There are better options for PHP public-key cryptography.
There are two big mistakes that people make when they decide to encrypt with RSA:
sodium_crypto_box_seal()
(libsodium)$keypair = sodium_crypto_box_keypair();
$publicKey = sodium_crypto_box_publickey($keypair);
// ...
$encrypted = sodium_crypto_box_seal(
$plaintextMessage,
$publicKey
);
// ...
$decrypted = sodium_crypto_box_seal_open(
$encrypted,
$keypair
);
Simple and secure. Libsodium will be available in PHP 7.2, or through PECL for earlier versions of PHP. If you need a pure-PHP polyfill, get paragonie/sodium_compat.
The only reason to use RSA in 2017 is, "I'm forbidden to install PECL extensions and therefore cannot use libsodium, and for some reason cannot use paragonie/sodium_compat either."
Your protocol should look something like this:
Instead of implementing this yourself, check out EasyRSA.
Further reading: Doing RSA in PHP correctly.
This will get you the difference between two DateTime objects in milliseconds:
DateTime d1 = new DateTime();
DateTime d2 = new DateTime();
long diffInMillis = d2.getMillis() - d1.getMillis();
I have tried the awnsers before but this did not work. Now I jsut used a LinearLayout instead of a TextureView, now it is working without any problem. Hope it helps some others who have the same problem. :)
view = (LinearLayout) findViewById(R.id.view); //this is initialized in the constructor
openWindowOnButtonClick();
public void openWindowOnButtonClick()
{
view.setAlpha((float)0.5);
FloatingActionButton fb = (FloatingActionButton) findViewById(R.id.floatingActionButton);
final InputMethodManager keyboard = (InputMethodManager) getSystemService(getBaseContext().INPUT_METHOD_SERVICE);
fb.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// check if the Overlay should be visible. If this value is false, it is not shown -> show it.
if(view.getVisibility() == View.INVISIBLE)
{
view.setVisibility(View.VISIBLE);
keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
Log.d("Overlay", "Klick");
}
else if(view.getVisibility() == View.VISIBLE)
{
view.setVisibility(View.INVISIBLE);
keyboard.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
}
Include the class that you are using Within your text file, then intelliSense will know where to look when you type within your text file. This works for me.
So it’s important to check the Unreal API to see where the included class is so that you have the path to type on the include line. Hope that makes sense.
Test with this in trackingCode.html:
<script type="text/javascript">
$(function() {
show_alert();
function show_alert() {
alert("Inside the jQuery ready");
}
});
</script>
Try setting a default value in the css (to let it know where you want it to start out)
position: relative;
transition: all 2s ease 0s;
top: 0; /* start out at position 0 */
Apple Docs:
- (id)initWithFrame:(CGRect)frame
collectionViewLayout:(UICollectionViewLayout *)layoutParameters
Use this method when initializing a collection view object programmatically. If you specify nil for the layout parameter, you must assign a layout object to the collectionViewLayout property before displaying the collection view onscreen. If you do not, the collection view will be unable to present any items onscreen.
This method is the designated initializer.
This method is used to initialize the UICollectionView
.
here you provide frame and a UICollectionViewLayout
object.
UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc]init];
At the end, add UICollectionView
as a subview
to your view.
Now collection view is added pro grammatically. You can go on learning.
Happy learning!! Hope it helps you.

I had a similar problem understanding why JpaRespository.getOne(id) does not work and throw an error.
I went and change to JpaRespository.findById(id) which requires you to return an Optional.
This is probably my first comment on StackOverflow.
Unfortunately, no. This feature is not available for facebook albums.
i found that i had a timer running in the background. when the activity is killed, yet the timer still running. in the timer finish callback i access fragment object to do some work, and here is the bug!!!! the fragment exists but the activity isn't.
if you have service of timer or any background threads, make sure to not access fragments objects.
You should look into require.js or head.js for this.

I have been playing around with using padding for center alignment. You will need to define the top level outer-container size, but the inner container should resize, and you can set the padding at different percentage values.
<div class='container'>
<img src='image.jpg' />
</div>
.container {
padding: 20%;
background-color: blue;
}
img {
width: 100%;
}
Use modulo
whenever a number x is a multiple of some number y, then always x % y equal to 0, which can be used as a check. So use
if (j % 4 == 0)
Not that simple:
python -c "import os; os.putenv('MY_DATA','1233')"
$ echo $MY_DATA # <- empty
But:
python -c "import os; os.putenv('MY_DATA','123'); os.system('bash')"
$ echo $MY_DATA #<- 123
Using display:inline-block;
it will work only for a correct sentence with spaces like

Why not using word-wrap: break-word;
? it's made to allow long words to be able to break and wrap onto the next line.

The easiest way I've found to place objects on the left is using FlowLayout.
JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
adding a component normally to this panel will place it on the left
ElementTree.Element
to a String?For Python 3:
xml_str = ElementTree.tostring(xml, encoding='unicode')
For Python 2:
xml_str = ElementTree.tostring(xml, encoding='utf-8')
The following is compatible with both Python 2 & 3, but only works for Latin characters:
xml_str = ElementTree.tostring(xml).decode()
from xml.etree import ElementTree
xml = ElementTree.Element("Person", Name="John")
xml_str = ElementTree.tostring(xml).decode()
print(xml_str)
Output:
<Person Name="John" />
Despite what the name implies, ElementTree.tostring()
returns a bytestring by default in Python 2 & 3. This is an issue in Python 3, which uses Unicode for strings.
In Python 2 you could use the
str
type for both text and binary data. Unfortunately this confluence of two different concepts could lead to brittle code which sometimes worked for either kind of data, sometimes not. [...]To make the distinction between text and binary data clearer and more pronounced, [Python 3] made text and binary data distinct types that cannot blindly be mixed together.
Source: Porting Python 2 Code to Python 3
If we know what version of Python is being used, we can specify the encoding as unicode
or utf-8
. Otherwise, if we need compatibility with both Python 2 & 3, we can use decode()
to convert into the correct type.
For reference, I've included a comparison of .tostring()
results between Python 2 and Python 3.
ElementTree.tostring(xml)
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />
ElementTree.tostring(xml, encoding='unicode')
# Python 3: <Person Name="John" />
# Python 2: LookupError: unknown encoding: unicode
ElementTree.tostring(xml, encoding='utf-8')
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />
ElementTree.tostring(xml).decode()
# Python 3: <Person Name="John" />
# Python 2: <Person Name="John" />
Thanks to Martijn Peters for pointing out that the str
datatype changed between Python 2 and 3.
In most scenarios, using str()
would be the "cannonical" way to convert an object to a string. Unfortunately, using this with Element
returns the object's location in memory as a hexstring, rather than a string representation of the object's data.
from xml.etree import ElementTree
xml = ElementTree.Element("Person", Name="John")
print(str(xml)) # <Element 'Person' at 0x00497A80>

Try this RegEx: Matching special charecters which we use in paragraphs and alphabets
Javascript : /^[a-zA-Z]+(([\'\,\.\-_ \/)(:][a-zA-Z_ ])?[a-zA-Z_ .]*)*$/.test(str)
.test(str) returns boolean value if matched true and not matched false
c# : ^[a-zA-Z]+(([\'\,\.\-_ \/)(:][a-zA-Z_ ])?[a-zA-Z_ .]*)*$
Note: For those dealing with CJK text (Chinese, Japanese, and Korean), the double-byte space (Unicode \u3000
) is not included in \s
for any implementation I've tried so far (Perl, .NET, PCRE, Python). You'll need to either normalize your strings first (such as by replacing all \u3000
with \u0020
), or you'll have to use a character set that includes this codepoint in addition to whatever other whitespace you're targeting, such as [ \t\u3000]
.
If you're using Perl or PCRE, you have the option of using the \h
shorthand for horizontal whitespace, which appears to include the single-byte space, double-byte space, and tab, among others. See the Match whitespace but not newlines (Perl) thread for more detail.
However, this \h
shorthand has not been implemented for .NET and C#, as best I've been able to tell.
This is a stronger regex replace that won't replace %% that are already doubled in the input.
str = str.replaceAll("(?:[^%]|\\A)%(?:[^%]|\\z)", "%%");

use parseInt
var total = parseInt(a) + parseInt(b);
$('#total_price').val(total);
Simply put:
SELECT *

Where 1/21/2012 is the date and you want all data, including that date.
SELECT *
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'
Use a between if you're selecting time between two dates

By default, the created subprocess does not have its own terminal or console. All its standard I/O (i.e. stdin, stdout, stderr) operations will be redirected to the parent process, where they can be accessed via the streams obtained using the methods getOutputStream(), getInputStream(), and getErrorStream(). The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, or even deadlock.
Kotlin standard lib doesn't provide Random Number Generator API. If you aren't in a multiplatform project, it's better to use the platform api (all the others answers of the question talk about this solution).
But if you are in a multiplatform context, the best solution is to implement random by yourself in pure kotlin for share the same random number generator between platforms. It's more simple for dev and testing.
To answer to this problem in my personal project, i implement a pure Kotlin Linear Congruential Generator. LCG is the algorithm used by java.util.Random
. Follow this link if you want to use it :
https://gist.github.com/11e5ddb567786af0ed1ae4d7f57441d4
My implementation purpose nextInt(range: IntRange)
for you ;).
Take care about my purpose, LCG is good for most of the use cases (simulation, games, etc...) but is not suitable for cryptographically usage because of the predictability of this method.
If anyone looking for a drop-in, zero-config and zero-dependencies library for the above use-case, try pace.js (http://github.hubspot.com/pace/docs/welcome/).
It automatically hooks to events (ajax, readyState, history pushstate, js event loop etc) and show a customizable loader.
Worked well with our react/relay projects (handles navigation changes using react-router, relay requests) (Not affliated; had used pace.js for our projects and it worked great)
When your class implements Comparable, the compareTo
method of the class is defining the "natural" ordering of that object. That method is contractually obligated (though not demanded) to be in line with other methods on that object, such as a 0 should always be returned for objects when the .equals()
comparisons return true.
A Comparator is its own definition of how to compare two objects, and can be used to compare objects in a way that might not align with the natural ordering.
For example, Strings are generally compared alphabetically. Thus the "a".compareTo("b")
would use alphabetical comparisons. If you wanted to compare Strings on length, you would need to write a custom comparator.
In short, there isn't much difference. They are both ends to similar means. In general implement comparable for natural order, (natural order definition is obviously open to interpretation), and write a comparator for other sorting or comparison needs.
For those looking for the shortex mutex example:
#include <mutex>
int main() {
std::mutex m;
m.lock();
// do thread-safe stuff
m.unlock();
}

just a note, I just installed mysql on an ubuntu 16.04 server. I tried different options in the following order:
sudo apt-get install python-mysqldb
: Was installed correctly, but unfortunatelly python returned ImportError: No module named 'mysql'
wget http://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python_2.1.4-1ubuntu16.04_all.deb
. Installed correctly with sudo dpckg -i package_name
, but python returned the same error. wget http://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-2.1.6.tar.gz
(used 2.1.4 at that time)tar -xf mysql-connector-python-2.1.6.tar.gz
cd mysql-connector-python-2.1.6/

Did not investigate why the first two failed, might try later. Hope this helps someone.
Save the following into a file with ".reg" suffix:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe]
"CodePage"=dword:0000fde9
Double click this file, and regedit will import it.
It basically sets the key HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe\CodePage
to 0xfde9 (65001 in decimal system).
Position the cursor inside the class, then press ALT + Ins and select Getters and Setters
from the contextual menu.
class foo(object):
mStatic = 12
def __init__(self):
self.x = "OBj"
Considering that foo has no access to x at all (FACT)
the conflict now is in accessing mStatic by an instance or directly by the class .
think of it in the terms of Python's memory management :
12 value is on the memory and the name mStatic (which accessible from the class)
points to it .
c1, c2 = foo(), foo()
this line makes two instances , which includes the name mStatic that points to the value 12 (till now) .
foo.mStatic = 99
this makes mStatic name pointing to a new place in the memory which has the value 99 inside it .
and because the (babies) c1 , c2 are still following (daddy) foo , they has the same name (c1.mStatic & c2.mStatic ) pointing to the same new value .
but once each baby decides to walk alone , things differs :
c1.mStatic ="c1 Control"
c2.mStatic ="c2 Control"
from now and later , each one in that family (c1,c2,foo) has its mStatica pointing to different value .
[Please, try use id() function for all of(c1,c2,foo) in different sates that we talked about , i think it will make things better ]
and this is how our real life goes . sons inherit some beliefs from their father and these beliefs still identical to father's ones until sons decide to change it .
HOPE IT WILL HELP
There are no PowerShell-native commands for Base64 conversion - yet (as of PowerShell [Core] 7.1), but adding dedicated cmdlets has been suggested.
For now, direct use of .NET is needed.
Important:
Base64 encoding is an encoding of binary data using bytes whose values are constrained to a well-defined 64-character subrange of the ASCII character set representing printable characters, devised at a time when sending arbitrary bytes was problematic, especially with the high bit set (byte values > 0x7f).
Therefore, you must always specify explicitly what character encoding the Base64 bytes do / should represent.
Ergo:
on converting TO Base64, you must first obtain a byte representation of the string you're trying to encode using the character encoding the consumer of the Base64 string expects.
on converting FROM Base64, you must interpret the resultant array of bytes as a string using the same encoding that was used to create the Base64 representation.
Examples:
Note:
The following examples convert to and from UTF-8 encoded strings:
To convert to and from UTF-16LE ("Unicode") instead, substitute [Text.Encoding]::Unicode
for [Text.Encoding]::UTF8
Convert TO Base64:
PS> [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes('Motörhead'))
TW90w7ZyaGVhZA==
Convert FROM Base64:
PS> [Text.Encoding]::Utf8.GetString([Convert]::FromBase64String('TW90w7ZyaGVhZA=='))
Motörhead
The Python with
statement is built-in language support of the Resource Acquisition Is Initialization
idiom commonly used in C++. It is intended to allow safe acquisition and release of operating system resources.
The with
statement creates resources within a scope/block. You write your code using the resources within the block. When the block exits the resources are cleanly released regardless of the outcome of the code in the block (that is whether the block exits normally or because of an exception).
Many resources in the Python library that obey the protocol required by the with
statement and so can used with it out-of-the-box. However anyone can make resources that can be used in a with statement by implementing the well documented protocol: PEP 0343
Use it whenever you acquire resources in your application that must be explicitly relinquished such as files, network connections, locks and the like.
It's working for me:
DependencyObject GetTopLevelControl(DependencyObject control)
{
DependencyObject tmp = control;
DependencyObject parent = null;
while((tmp = VisualTreeHelper.GetParent(tmp)) != null)
{
parent = tmp;
}
return parent;
}
The name of the spyder executable was changed to spyder3.exe in python version 3. I install pyqt5 and spyder via pip and was able to launch spyder3. I first tried without installing pyqt5 and nothing happened. Once I installed pyqt5, then spyder 3 opened.
Try the following from a windows cmd.exe prompt:
C:\Users\..>pip install pyqt5
C:\Users\..>pip install spyder
C:\Users\..>spyder3
The following code -
element.sendKeys("");
tries to find an input tag box to enter some information, while
new Actions(driver).moveToElement(element).perform();
is more appropriate as it will work for image elements, link elements, dropdown boxes etc.
Therefore using moveToElement() method makes more sense to focus on any generic WebElement on the web page.
For an input box you will have to click() on the element to focus.
new Actions(driver).moveToElement(element).click().perform();
while for links and images the mouse will be over that particular element,you can decide to click() on it depending on what you want to do.
If the click() on an input tag does not work -
Since you want this function to be generic, you first check if the webElement is an input tag or not by -
if("input".equals(element.getTagName()){
element.sendKeys("");
}
else{
new Actions(driver).moveToElement(element).perform();
}
You can make similar changes based on your preferences.

You can compare for exactly the same type using:
class A {
}
var a = new A();
var typeOfa = a.GetType();
if (typeOfa == typeof(A)) {
}
typeof returns the Type object from a given class.
But if you have a type B, that inherits from A, then this comparison is false. And you are looking for IsAssignableFrom.
class B : A {
}
var b = new B();
var typeOfb = b.GetType();
if (typeOfb == typeof(A)) { // false
}
if (typeof(A).IsAssignableFrom(typeOfb)) { // true
}
You can add "download" attribute inside your tag to download files.

One way to do this is to create an instance of the ofstream class, and use it to write to your file. Here's a link to a website that has some example code, and some more information about the standard tools available with most implementations of C++:
For completeness, here's some example code:
// using ofstream constructors.
#include <iostream>
#include <fstream>
std::ofstream outfile ("test.txt");
outfile << "my text here!" << std::endl;
outfile.close();
You want to use std::endl to end your lines. An alternative is using '\n' character. These two things are different, std::endl flushes the buffer and writes your output immediately while '\n' allows the outfile to put all of your output into a buffer and maybe write it later.
On my localhost everything was ok, but on server it helped me “set_locale” and “utf-8” at “mb_strtolower”.
<?
setlocale( LC_ALL, "en_US.UTF8" );
function slug( $str, $char = "-", $tf = "lowercase" )
{
$str = iconv( "utf-8", "us-ascii//translit//ignore", $str ); // transliterate
$str = str_replace( "'", "", $str ); // remove “'” generated by iconv
$str = preg_replace( "~[^a-z0-9]+~ui", $char, $str ); // replace unwanted by single “-”
$str = trim( $str, $char ); // trim “-”
if( $tf == "lowercase" ) $str = mb_strtolower( $str, "utf-8" ); // lowercase
elseif( $tf == "uppercase" ) $str = mb_strtoupper( $str, "utf-8" );
return $str;
}
?>
Test
$string = "--+ešcržýá091354--––—_-6íé???ß?ac … elnszzAC ELNS Z///+++||||..Z";

Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).
It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).
But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.
A good example: here
And a good documentation from Mozilla: here
As you need access to your hostname variable in every component, and to change it to localhost while in development mode, or to production hostname when in production mode, you can define this variable in the prototype.
Like this:
Vue.prototype.$hostname = 'http://localhost:3000'
And $hostname will be available in all Vue instances:
new Vue({
beforeCreate: function () {
console.log(this.$hostname)
}
})
In my case, to automatically change from development to production, I've defined the $hostname prototype according to a Vue production tip variable in the file where I instantiated the Vue.
Like this:
Vue.config.productionTip = false
Vue.prototype.$hostname = (Vue.config.productionTip) ? 'https://hostname' : 'http://localhost:3000'
An example can be found in the docs: Documentation on Adding Instance Properties
More about production tip config can be found here:

Not having a compiler by me right now, I'll answer by asking a question:
Have you tried this? Does it work?
long key = -1L;
PreparedStatement statement = connection.prepareStatement();
statement.executeUpdate(YOUR_SQL_HERE, PreparedStatement.RETURN_GENERATED_KEYS);
ResultSet rs = statement.getGeneratedKeys();
if (rs != null && rs.next()) {
key = rs.getLong(1);
}
Disclaimer: Obviously, I haven't compiled this, but you get the idea.
PreparedStatement is a subinterface of Statement, so I don't see a reason why this wouldn't work, unless some JDBC drivers are buggy.
I had a similar problem to yours on windows as the following.
D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex
adb: error: failed to copy '/data/local/tmp/com.packagename_dumped_1766.dex' to 'D:\ProgramFiles\Android\com.packagename_dumped_1766.dex': remote Permission denied
My solution:
At first I also made an attempt to use cat
as ansi_lumen answered, but I got into trouble about CR and LR (\r\n
) characters.
And then I just had to change those file permisions by chmod
and pulled again to this problem was solved without introducing other problems. After that, may
we need to restore their original permissions as Goran Devs answered.
So just pay a little attention.
TL;DR
My story:
Firstly, I used the cat
to download all files from android to my windows,
@echo off
cd /d %~dp0
:: %~dp0 = D:\ProgramFiles\Android\
SET ThisBatDir=%~dp0
:: adb shell ls /data/local/tmp/com.packagename_dumped_* > %~dp0\dump_file_list.txt
FOR /f "delims=" %%a in ('adb shell ls /data/local/tmp/com.packagename_dumped_*') do call :processline %%a %%~nxa
goto :eof
:: https://stackoverflow.com/questions/232651/why-the-system-cannot-find-the-batch-label-specified-is-thrown-even-if-label-e
:processline
SET RemoteFullPath=%1
set FileName=%2
:: echo "%RemoteFullPath%|%ThisBatDir%|%FileName%"
call adb shell su -c cat %RemoteFullPath% > %ThisBatDir%%FileName%
goto :eof
:eof
However, those downloaded dex
files were broken because of CR and LR (\r\n
) characters on windows.
We can use hexdump
to inspect its content in Hex+ASCII form (or Notepad++ with "View > Show Symbol > Show All Characters" checked). Note, the 5th and 6th byte (0d 0a)).

D:\ProgramFiles\Android> adb shell ls -l /data/local/tmp
-rwxrwxrwx root root 57344 2020-03-28 17:45 com.packagename_dumped_1766.dex
As a result, I made it.
D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex

JPA is an API, one which Hibernate implements.Hibernate predates JPA. Before JPA, you write native hibernate code to do your ORM. JPA is just the interface, so now you write JPA code and you need to find an implementation. Hibernate happens to be an implementation.
So your choices are this: hibernate, toplink, etc...
The advantage to JPA is that it allows you to swap out your implementation if need be. The disadvantage is that the native hibernate/toplink/etc... API may offer functionality that the JPA specification doesn't support.
Another fast solution that saves boilerplate code is Lombok EqualsAndHashCode annotation. It is easy, elegant and customizable. And does not depends on the IDE. For example;
import lombok.EqualsAndHashCode;
@EqualsAndHashCode(of={"errorNumber","messageCode"}) // Will only use this fields to generate equals.
public class ErrorMessage{
private long errorNumber;
private int numberOfParameters;
private Level loggingLevel;
private String messageCode;
See the options avaliable to customize which fields to use in the equals. Lombok is avalaible in maven. Just add it with provided scope:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.14.8</version>
<scope>provided</scope>
</dependency>
You don't have a continuous block of memory in order to allocate 762MB, your memory is fragmented and the allocator cannot find a big enough hole to allocate the needed memory.
There should not be a space after name
.
Incorrect:
{% url 'author' name = p.article_author.name.username %}
Correct:
{% url 'author' name=p.article_author.name.username %}
Set a breakpoint on malloc_error_break() by opening the Breakpoint Navigator (View->Navigators->Show Breakpoint Navigator or ?8), clicking the plus button in the lower left corner, and selecting "Add Symbolic Breakpoint". In the popup that comes up, enter malloc_error_break
in the Symbol field, then click Done.
EDIT: openfrog added a screenshot and indicated that he's already tried these steps without success after I posted my answer. With that edit, I'm not sure what to say. I haven't seen that fail to work myself, and indeed I always keep a breakpoint on malloc_error_break set.
To improve upon the answer with the most upticks, some of you may have noticed on the initial load of the page that the chevrons all point in the same direction. This is corrected by adding the class "collapsed" to elements that you want to load collapsed.

Here is a working fiddle: http://jsfiddle.net/3gYa3/585/
Are you looking for the following?
File.open(yourfile, 'w') { |file| file.write("your text") }
given you have a div element you need to scroll inside, try this piece of code
document.querySelector('div').scroll(x,y)
this works with me inside a div with a scroll, this should work with you in case you pointed the mouse over this element and then tried to scroll down or up. If it manually works, it should work too
I think this will work even though this was forever ago.
SELECT employee_number, Row_Number()
OVER (PARTITION BY course_code ORDER BY course_completion_date DESC ) as rownum
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
AND rownum = 1
If you want to get the last Id if the date is the same then you can use this assuming your primary key is Id.
SELECT employee_number, Row_Number()
OVER (PARTITION BY course_code ORDER BY course_completion_date DESC, Id Desc) as rownum FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
AND rownum = 1
My solution here is to loop, just to avoid duplicate option
<select class="form-control" name="status" >
<?php $lists = ['Current', 'Win', 'Lose']; ?>
@foreach($lists as $list)
<option value={{$list}} {{(old('status') == $list?'selected':'')}} >{{$list}}</option>
@endforeach
</select>
When using a glob pattern, a question mark represents a single character and an asterisk represents a sequence of zero or more characters:
if [[ $gg == ????grid* ]] ; then echo $gg; fi
When using a regular expression, a dot represents a single character and an asterisk represents zero or more of the preceding character. So ".*
" represents zero or more of any character, "a*
" represents zero or more "a", "[0-9]*
" represents zero or more digits. Another useful one (among many) is the plus sign which represents one or more of the preceding character. So "[a-z]+
" represents one or more lowercase alpha character (in the C locale - and some others).
if [[ $gg =~ ^....grid.*$ ]] ; then echo $gg; fi
For remove in NestJS need to add option to Shema() decorator

I know this post is old but here is what I found.
It doesn't work when I link it this way(with /
before css/style.css
on the href
attribute.
<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />
However, when I removed /
I'm able to link properly with the css file
It should be like this(without /
).
<link rel="stylesheet" media="all" href="CSS/Style.css" type="text/css" />
This was giving me trouble on my project. Hope it will help somebody else.
Use mktemp -d
. It creates a temporary directory with a random name and makes sure that file doesn't already exist. You need to remember to delete the directory after using it though.
The MySQL documentation has information on mapping MySQL types to Java types. In general, for MySQL datetime and timestamps you should use java.sql.Timestamp
. A few resources include:

EDIT:
As others have indicated, the suggestion of using strings may lead to issues.
UPDATE your_table set your_field="" where your_field is null
Dennis answer is correct. However I would like to explain the solution in a bit more detailed way (for Windows User):
regedit
into the search field.HKEY_LOCAL_MACHINE\Software\JavaSoft
(Windows 10 seems to now have this here: HKEY_LOCAL_MACHINE\Software\WOW6432Node\JavaSoft
)New
-> Key
Prefs
and everything should work.Alternatively, save and execute a *.reg
file with the following content:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs]
I just tried on windows XP, it worked
local computer: sc \\. delete [service-name]
Deleting services in Windows Server 2003
We can use sc.exe in the Windows Server 2003 to control services, create services and delete services. Since some people thought they must directly modify the registry to delete a service, I would like to share how to use sc.exe to delete a service without directly modifying the registry so that decreased the possibility for system failures.
To delete a service:
Click “start“ - “run“, and then enter “cmd“ to open Microsoft Command Console.
Enter command:
sc servername delete servicename
For instance, sc \\dc delete myservice
(Note: In this example, dc is my Domain Controller Server name, which is not the local machine, myservice is the name of the service I want to delete on the DC server.)
Below is the official help of all sc functions:
DESCRIPTION:
SC is a command line program used for communicating with the
NT Service Controller and services.
