In my case: I forgot to activate virtualenv
I installed "pip install example" in the wrong virtualenv
You are using a forward declaration for the type MainWindowClass
. That's fine, but it also means that you can only declare a pointer or reference to that type. Otherwise the compiler has no idea how to allocate the parent object as it doesn't know the size of the forward declared type (or if it actually has a parameterless constructor, etc.)
So, you either want:
// forward declaration, details unknown
class A;
class B {
A *a; // pointer to A, ok
};
Or, if you can't use a pointer or reference....
// declaration of A
#include "A.h"
class B {
A a; // ok, declaration of A is known
};
At some point, the compiler needs to know the details of A
.
If you are only storing a pointer to A
then it doesn't need those details when you declare B
. It needs them at some point (whenever you actually dereference the pointer to A
), which will likely be in the implementation file, where you will need to include the header which contains the declaration of the class A
.
// B.h
// header file
// forward declaration, details unknown
class A;
class B {
public:
void foo();
private:
A *a; // pointer to A, ok
};
// B.cpp
// implementation file
#include "B.h"
#include "A.h" // declaration of A
B::foo() {
// here we need to know the declaration of A
a->whatever();
}

void QWidget::setWindowTitle ( const QString & )
EDIT: If you are using QtDesigner, on the property tab, there is an editable property called windowTitle which can be found under the QWidget section. The property tab can usually be found on the lower right part of the designer window.
For future people struggling with a similar problem, the situation is that the compiler simply cannot find the type you are using (even if your Intelisense can find it).
This can be caused in many ways:
#include
the header that defines it.#ifndef BLAH_H
) are defective (your #ifndef BLAH_H
doesn't match your #define BALH_H
due to a typo or copy+paste mistake).#define MYHEADER_H
, even if they are in separate directories)new Vector()
should be new Vector<int>()
)NamespaceA::NamespaceB
, AND a <global scope>::NamespaceB
, if you are already within NamespaceA
, it'll look in NamespaceA::NamespaceB
and not bother checking <global scope>::NamespaceB
) unless you explicitly access it.To explicitly access something in the global namespace, prefix it with ::
, as if the global namespace is a namespace with no name (e.g. ::MyType
or ::MyNamespace::MyType
).
'Common Table Expression' feature is not available in MySQL, so you have to go to make a view or temporary table to solve, here I have used a temporary table.
The stored procedure mentioned here will solve your need. If I want to get all my team members and their associated members, this stored procedure will help:
----------------------------------
user_id | team_id
----------------------------------
admin | NULL
ramu | admin
suresh | admin
kumar | ramu
mahesh | ramu
randiv | suresh
-----------------------------------
Code:
DROP PROCEDURE `user_hier`//
CREATE DEFINER=`root`@`localhost` PROCEDURE `user_hier`(in team_id varchar(50))
BEGIN
declare count int;
declare tmp_team_id varchar(50);
CREATE TEMPORARY TABLE res_hier(user_id varchar(50),team_id varchar(50))engine=memory;
CREATE TEMPORARY TABLE tmp_hier(user_id varchar(50),team_id varchar(50))engine=memory;
set tmp_team_id = team_id;
SELECT COUNT(*) INTO count FROM user_table WHERE user_table.team_id=tmp_team_id;
WHILE count>0 DO
insert into res_hier select user_table.user_id,user_table.team_id from user_table where user_table.team_id=tmp_team_id;
insert into tmp_hier select user_table.user_id,user_table.team_id from user_table where user_table.team_id=tmp_team_id;
select user_id into tmp_team_id from tmp_hier limit 0,1;
select count(*) into count from tmp_hier;
delete from tmp_hier where user_id=tmp_team_id;
end while;
select * from res_hier;
drop temporary table if exists res_hier;
drop temporary table if exists tmp_hier;
end
This can be called using:
mysql>call user_hier ('admin')//
I would use a generic iterator of property/value over the array. No jQuery required.
arr = [{prop1: 'val1', prop2: 'val2'}, {prop1: 'val3', prop2: 'val4'}];
objectPropInArray(arr, 'prop1', 'val3'); // <-- returns true
function objectPropInArray(list, prop, val) {
if (list.length > 0 ) {
for (i in list) {
if (list[i][prop] === val) {
return true;
}
}
}
return false;

It work for me. I hope it can hepl you!
I would like to add that Using the library momentjs in javascript you can have the whole data information in an object with:
const today = moment(1557697070824.94).toObject();
You should obtain an object with this properties:
today: {
date: 15,
hours: 2,
milliseconds: 207,
minutes: 31,
months: 4
seconds: 22,
years: 2019
}
It is very useful when you have to calculate dates.
You can use File.Exists to check if the file exists and create it using File.Create if required. Make sure you check if you have access to create files at that location.
Once you are certain that the file exists, you can write to it safely. Though as a precaution, you should put your code into a try...catch block and catch for the exceptions that function is likely to raise if things don't go exactly as planned.
The path for your git is invalid. Copy the path from File -> Settings -> Version Control -> Git and search that folder and you can see the path to your Git is not valid. Reset the path with correct location and test it. The error should be gone.
In my case, Get specific version, even checking both check boxes and undoing all pending changes didn't work.
Checked the work spaces. Edit current workspace. Check all paths. The solution path was incorrect and was pointing to a deleted folder.
Fixed the path and get latest worked fine.
This RE will do:
/^(?:[0-9]+[a-z]|[a-z]+[0-9])[a-z0-9]*$/i
Explanation of RE:
(?:...)
creates an unreferenced group/i
is the ignore-case flag, so that a-z
== a-zA-Z
.You need to use v-bind:
or its alias :
. For example,
<a v-bind:href="'/job/'+ r.id">
or
<a :href="'/job/' + r.id">
Might be you forgotten to place the Main class and Test Case class in /src/test/java. Check it Once.
Probably very trivial, but I solved it by just converting the input to numpy array.
For the neural network architecture,
model = Sequential()
model.add(Conv2D(32, (5, 5), activation="relu", input_shape=(32, 32, 3)))
When the input was,
n_train = len(train_y_raw)
train_X = [train_X_raw[:,:,:,i] for i in range(n_train)]
train_y = [train_y_raw[i][0] for i in range(n_train)]
But when I changed it to,
n_train = len(train_y_raw)
train_X = np.asarray([train_X_raw[:,:,:,i] for i in range(n_train)])
train_y = np.asarray([train_y_raw[i][0] for i in range(n_train)])
It fixed the issue.
I found the answer, and in spite of what I reported, it was NOT browser specific. The bug was in my function code, and would have occurred in any browser. It boils down to this. I had two lines in my code that were FireFox/FireBug specific. They used console.log. In IE, they threw an error, so I commented them out (or so I thought). I did a crappy job commenting them out, and broke the bracketing in my function.
Original Code (with console.log in it):
if (sxti.length <= 50) console.log('sxti=' + sxti);
if (sxph.length <= 50) console.log('sxph=' + sxph);
Broken Code (misplaced brackets inside comments):
if (sxti.length <= 50) { //console.log('sxti=' + sxti); }
if (sxph.length <= 50) { //console.log('sxph=' + sxph); }
Fixed Code (fixed brackets outside comments):
if (sxti.length <= 50) { }//console.log('sxti=' + sxti);
if (sxph.length <= 50) { }//console.log('sxph=' + sxph);
So, it was my own sloppy coding. The function really wasn't defined, because a syntax error kept it from being closed.
Oh well, live and learn. ;)
I came across the same issue as well. Not sure why this is working but it indeed works: Try add ENGINE INNODB after your create query.
mysql> create table course
-> (course_id varchar(7),
-> title varchar (50),
-> dept_name varchar(20),
-> credits numeric(2,0),
-> primary key(course_id),
-> foreign key (dept_name) references department) ENGINE INNODB;
I know this is an old question but thought I'd share how I resolved the issue.
If you're using Visual Studio and this error occurs, you can try to attach to process (CTRL+ALT+P) and find the "(program).exe" process. When you try to attach to it, an error will display stating that it failed to attach which removes the process from "running" (even though it's not...) You'll also be able to delete the (program).exe from your Debug folder.
Hope this helps someone! :)

In Chrome (possible Safari too) you can inspect an element, then right click on the tag you want to get the xpath for, then you can copy the xpath to select that element.
That depends on what you want to do, but as you said, getting an entity reference using find()
and then just updating that entity is the easiest way to do that.
I'd not bother about performance differences of the various methods unless you have strong indications that this really matters.
Basing on this tutorial, here a very basic way to do that:
$('your_trigger_element_selector').on('click', function(){
var data = new FormData();
data.append('input_file_name', $('your_file_input_selector').prop('files')[0]);
// append other variables to data if you want: data.append('field_name_x', field_value_x);
$.ajax({
type: 'POST',
processData: false, // important
contentType: false, // important
data: data,
url: your_ajax_path,
dataType : 'json',
// in PHP you can call and process file in the same way as if it was submitted from a form:
// $_FILES['input_file_name']
success: function(jsonData){
...
}
...
});
});
Don't forget to add proper error handling
As I understand it, this is the default way of using the web driver.
Which whitespace character? The empty string is pretty unambiguous - it's a sequence of 0 characters. However, " "
, "\t"
and "\n"
are all strings containing a single character which is characterized as whitespace.
If you just mean a space, use a space. If you mean some other whitespace character, there may well be a custom escape sequence for it (e.g. "\t"
for tab) or you can use a Unicode escape sequence ("\uxxxx"
). I would discourage you from including non-ASCII characters in your source code, particularly whitespace ones.
EDIT: Now that you've explained what you want to do (which should have been in your question to start with) you'd be better off using Regex.Split
with a regular expression of \s
which represents whitespace:
Regex regex = new Regex(@"\s");
string[] bits = regex.Split(text.ToLower());
See the Regex Character Classes documentation for more information on other character classes.
I am going to assume this is a WinForms questions (which it feels like, based on it being a "program" rather than a website/app). In which case you can simple do the following to change the text colour of a label:
myLabel.ForeColor = System.Drawing.Color.Red;
Or any other colour of your choice. If you want to be more specific you can use an RGB value like so:
myLabel.ForeColor = Color.FromArgb(0, 0, 0);//(R, G, B) (0, 0, 0 = black)
Having different colours for different users can be done a number of ways. For example, you could allow each user to specify their own RGB value colours, store these somewhere and then load them when the user "connects".
An alternative method could be to just use 2 colours - 1 for the current user (running the app) and another colour for everyone else. This would help the user quickly identify their own messages above others.
A third approach could be to generate the colour randomly - however you will likely get conflicting values that do not show well against your background, so I would suggest not taking this approach. You could have a pre-defined list of "acceptable" colours and just pop one from that list for each user that joins.
When you use Object.defineProperties
, by default writable
is set to false
, so _year
and edition
are actually read only properties.
Explicitly set them to writable: true
:
_year: {
value: 2004,
writable: true
},
edition: {
value: 1,
writable: true
},
Check out MDN for this method.
writable
true
if and only if the value associated with the property may be changed with an assignment operator.

I also got a similar error when forced to use TLS1.2 for java 6. And I handled it thanks to this library:
Clone Source Code: https://github.com/tobszarny/ssl-provider-jvm16
Add Main Class:
public static void main(String[] args) throws Exception {
try {
String apiUrl = "https://domain/api/query?test=123";
URL myurl = new URL(apiUrl);
HttpsURLConnection con = (HttpsURLConnection) myurl.openConnection();
con.setSSLSocketFactory(new TSLSocketConnectionFactory());
int responseCode = con.getResponseCode();
System.out.println("GET Response Code :: " + responseCode);
} catch (Exception ex) {
ex.printStackTrace();
}
}
As a side note, consider passing strings in setWord() as const references to avoid excess copying. Also, in displayWord, consider making this a const function to follow const-correctness.
void setWord(const std::string& word) {
theWord = word;
}
Make the builder a static
class. Then it will work. If it is non-static, it would require an instance of its owning class - and the point is not to have an instance of it, and even to forbid making instances without the builder.
public class NutritionFacts {
public static class Builder {
}
}
Reference: Nested classes
This works:
var form = $(this).closest('form');
form = form.serializeArray();
form = form.concat([
{name: "customer_id", value: window.username},
{name: "post_action", value: "Update Information"}
]);
$.post('/change-user-details', form, function(d) {
if (d.error) {
alert("There was a problem updating your user details")
}
});
I would suggest the use of exists
instead of in
because in some scenarios that implies null values the behavior is different, so
CREATE TRIGGER sampleTrigger

Check your routing method:
if your routing state is like this
.state('app.register', {
url: '/register',
views: {
'menuContent': {
templateUrl: 'templates/register.html',
}
}
})
then you should use
$location.path("/app/register");
You can create one more class naming
.flex-control-thumbs-without-width li {
width: auto;
float: initial; or none
}
Add this class whenever you need to override like below,
<li class="flex-control-thumbs flex-control-thumbs-without-width"> </li>
And do remove whenever you don't need for other <li>
I use this time format: "{birthDate": "2018-05-24T13:56:13Z}"

What worked for me was adding a div around the content. Originally i had this. Css applied to the td had no effect.
<td>
@Html.DisplayFor(modelItem => item.Message)
</td>
Then I wrapped the content in a div and the css worked as expected
<td>
<div class="largeContent">
@Html.DisplayFor(modelItem => item.Message)
</div>
</td>
Got a solution that runs. Don't know if it is optimal though. What I do is to split the string according to http://blogs.oracle.com/aramamoo/2010/05/how_to_split_comma_separated_string_and_pass_to_in_clause_of_select_statement.html

For AutoCompleteTextView
things are more complicated because wrapping it in TextInputLayout
and applying this theme breaks floating label behaviour.
You need to fix this in code:
private void setStyleForTextForAutoComplete(int color) {
Drawable wrappedDrawable = DrawableCompat.wrap(autoCompleteTextView.getBackground());
DrawableCompat.setTint(wrappedDrawable, color);
autoCompleteTextView.setBackgroundDrawable(wrappedDrawable);
}
and in Activity.onCreate
:
setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
autoCompleteTextView.setOnFocusChangeListener((v, hasFocus) -> {
if(hasFocus) {
setStyleForTextForAutoComplete(getResources().getColor(R.color.blue));
} else {
if(autoCompleteTextView.getText().length() == 0) {
setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
}
}
});
You can also use Ghostscript to merge different PDFs. You can even use it to merge a mix of PDFs, PostScript (PS) and EPS into one single output PDF file:
gs \
-o merged.pdf \
-sDEVICE=pdfwrite \
-dPDFSETTINGS=/prepress \
input_1.pdf \
input_2.pdf \
input_3.eps \
input_4.ps \
input_5.pdf
However, I agree with other answers: for your use case of merging PDF file types only, pdftk
may be the best (and certainly fastest) option.
Update:
If processing time is not the main concern, but if the main concern is file size (or a fine-grained control over certain features of the output file), then the Ghostscript way certainly offers more power to you. To highlight a few of the differences:
You can use Instance.ToShortDateString() for the date,
and Instance.ToShortTimeString() for the time to get date and time from the same instance.
One of the Related posts gave me the (simple) answer.
Apparently the auto
value on the grid-template-rows
property does exactly what I was looking for.
.grid {
display:grid;
grid-template-columns: 1fr 1.5fr 1fr;
grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
grid-gap:10px;
height: calc(100vh - 10px);
}
I have use below code to encode the special character by specifying encode format.
String text = "This is an example é";
byte[] byteText = text.getBytes(Charset.forName("UTF-8"));
//To get original string from byte.
String originalString= new String(byteText , "UTF-8");
delete from table where id <> 2
edit: to correct syntax for MySQL
It is really hard to determine if it is iso-8859-1. If you have a text with only 7 bit characters that could also be iso-8859-1 but you don't know. If you have 8 bit characters then the upper region characters exist in order encodings as well. Therefor you would have to use a dictionary to get a better guess which word it is and determine from there which letter it must be. Finally if you detect that it might be utf-8 than you are sure it is not iso-8859-1
Encoding is one of the hardest things to do because you never know if nothing is telling you
Modals always load the content into an element on the page, which more often than not is a div
. Think of this div
as the iframe
equivalent when it comes to jQuery UI Dialogs. Now it depends on your requirements whether you want static content that resides within the page or you want to fetch the content from some other location. You may use this code and see if it works for you:

There are, however, a few things which you should keep in mind. You will not be able to load remote URL's on your local system, you need to upload to a server if you want to load remote URL. Even then, you may only load URL's which belong to the same domain; e.g. if you upload this file to 'www.example.com' you may only access files hosted on 'www.example.com'. For loading external links this might help. All this information you will find in the link as suggested by @Robin.
how about (for char c
)
int i = (int)(c - '0');
which does substraction of the char value?
Re the API question (comments), perhaps an extension method?
public static class CharExtensions {
public static int ParseInt32(this char value) {
int i = (int)(value - '0');
if (i < 0 || i > 9) throw new ArgumentOutOfRangeException("value");
return i;
}
}
then use int x = c.ParseInt32();
from manual:
: [arguments] No effect; the command does nothing beyond expanding arguments and performing any specified redirections. A zero exit code is returned.
As this returns always zero therefore is is similar to be used as true

I did some research and found out that byte.Parse is even slower than Convert.ToByte. The fastest conversion I could come up with uses approximately 15 ticks per byte.
public static byte[] StringToByteArrayFastest(string hex) {
if (hex.Length % 2 == 1)
throw new Exception("The binary key cannot have an odd number of digits");
byte[] arr = new byte[hex.Length >> 1];
for (int i = 0; i < hex.Length >> 1; ++i)
{
arr[i] = (byte)((GetHexVal(hex[i << 1]) << 4) + (GetHexVal(hex[(i << 1) + 1])));
}
return arr;
}
public static int GetHexVal(char hex) {
int val = (int)hex;
//For uppercase A-F letters:
//return val - (val < 58 ? 48 : 55);
//For lowercase a-f letters:
//return val - (val < 58 ? 48 : 87);
//Or the two combined, but a bit slower:
return val - (val < 58 ? 48 : (val < 97 ? 55 : 87));
}
// also works on .NET Micro Framework where (in SDK4.3) byte.Parse(string) only permits integer formats.

The current "pipable" variant of this operator is called finalize()
(since RxJS 6). The older and now deprecated "patch" operator was called finally()
(until RxJS 5.5).
I think finalize()
operator is actually correct. You say:
do that logic only when I subscribe, and after the stream has ended
which is not a problem I think. You can have a single source
and use finalize()
before subscribing to it if you want. This way you're not required to always use finalize()
:
let source = new Observable(observer => {
observer.next(1);
observer.error('error message');
observer.next(3);
observer.complete();
}).pipe(
publish(),
);
source.pipe(
finalize(() => console.log('Finally callback')),
).subscribe(
value => console.log('#1 Next:', value),
error => console.log('#1 Error:', error),
() => console.log('#1 Complete')
);
source.subscribe(
value => console.log('#2 Next:', value),
error => console.log('#2 Error:', error),
() => console.log('#2 Complete')
);
source.connect();
This prints to console:
#1 Next: 1
#2 Next: 1
#1 Error: error message
Finally callback
#2 Error: error message

As mentioned by removing the colon :
and replacing with slash /
before the sid worked for me.
I have had this issue before, too.
The idiom (shared by quite a few other languages) for an unused variable is a single underscore _
. Code analysers typically won't complain about _
being unused, and programmers will instantly know it's a shortcut for i_dont_care_wtf_you_put_here
. There is no way to iterate without having an item variable - as the Zen of Python puts it, "special cases aren't special enough to break the rules".
Yes, you need OpenSSL to work correctly. My backup testing site worked, my live server didn't. Difference? Live server didn't have OpenSSL within PHP configuration.
As an example, I am using a login modal window, where the modal window is the parent, the login form is the child and the login button calls back to the modal parent's close function.
The parent modal contains the function to close the modal. This parent passes the close function to the login child component.
import { Component} from '@angular/core';
import { LoginFormComponent } from './login-form.component'
@Component({
selector: 'my-modal',
template: `<modal #modal>
<login-form (onClose)="onClose($event)" ></login-form>
</modal>`
})
export class ParentModalComponent {
modal: {...};
onClose() {
this.modal.close();
}
}
After the child login component submits the login form, it closes the parent modal using the parent's callback function
import { Component, EventEmitter, Output } from '@angular/core';
@Component({
selector: 'login-form',
template: `<form (ngSubmit)="onSubmit()" #loginForm="ngForm">
<button type="submit">Submit</button>
</form>`
})
export class ChildLoginComponent {
@Output() onClose = new EventEmitter();
submitted = false;
onSubmit() {
this.onClose.emit();
this.submitted = true;
}
}
A list is considered to be False
if it has no elements, so you can do something like this:
{% if mylist %}
<p>I have a list!</p>
{% else %}
<p>I don't have a list!</p>
{% endif %}
TL;DR Use GetProcessVersion
.
All of these function are available in Windows XP [desktop apps | UWP apps].
GetProcessVersion
uses a Process ID and returns 0 if the process of the given id is not running.
GetExitCodeProcess
uses a Process handle and gives you the process exit code, if the code is STILL_ACTIVE (259) the process is still running so you could check if it is not STILL_ACTIVE (259) meaning that the process is not running. This is likely to work in basically every situation, unless the process exits with code 259.
WaitForSingleObject
uses a Process handle with the SYNCHRONIZE access right and returns 0 if the process is not running. You should not specify INFINITE for the dwMilliseconds parameter because the function would not return until the process state became signaled(process is terminated).
The right answer (using Python 2.7 and later, since check_output()
was introduced then) is:
py2output = subprocess.check_output(['python','py2.py','-i', 'test.txt'])
To demonstrate, here are my two programs:
py2.py:
import sys
print sys.argv
py3.py:
import subprocess
py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'])
print('py2 said:', py2output)
Running it:
$ python3 py3.py
py2 said: b"['py2.py', '-i', 'test.txt']\n"
Here's what's wrong with each of your versions:
py2output = subprocess.check_output([str('python py2.py '),'-i', 'test.txt'])
First, str('python py2.py')
is exactly the same thing as 'python py2.py'
—you're taking a str
, and calling str
to convert it to an str
. This makes the code harder to read, longer, and even slower, without adding any benefit.
More seriously, python py2.py
can't be a single argument, unless you're actually trying to run a program named, say, /usr/bin/python\ py2.py
. Which you're not; you're trying to run, say, /usr/bin/python
with first argument py2.py
. So, you need to make them separate elements in the list.
Your second version fixes that, but you're missing the '
before test.txt'
. This should give you a SyntaxError
, probably saying EOL while scanning string literal
.
Meanwhile, I'm not sure how you found documentation but couldn't find any examples with arguments. The very first example is:
>>> subprocess.check_output(["echo", "Hello World!"])
b'Hello World!\n'
That calls the "echo"
command with an additional argument, "Hello World!"
.
Also:
-i is a positional argument for argparse, test.txt is what the -i is
I'm pretty sure -i
is not a positional argument, but an optional argument. Otherwise, the second half of the sentence makes no sense.
First you don't need to change anything yet.
Those nonstandard behaviors remain the default for TIMESTAMP but as of MySQL 5.6.6 are deprecated and this warning appears at startup
Now if you want to move to new behaviors you have to add this line in your my.cnf
in the [mysqld] section.
explicit_defaults_for_timestamp = 1
The location of my.cnf (or other config files) vary from one system to another. If you can't find it refer to https://dev.mysql.com/doc/refman/5.7/en/option-files.html
I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:
multiDexEnabled true
And it worked!
Example
android {
compileSdkVersion 27
buildToolsVersion '27.0.1'
defaultConfig {
applicationId "com.xx.xxx"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
multiDexEnabled true //Add this
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
And clean the project.
I was using eclipse and after trying all the other answers it didn't work for me.
In the end, what worked for me was moving the ojdb7.jar
to top in the Build Path. This occurs when multiple jars have conflicting same classes.
- Select project in
Project Explorer
- Right click on
Project -> Build Path -> Configure Build Path
- Go to
Order and Export
tab and selectojdbc.jar
- Click button
TOP
to move it to top
The Uri.parse(extras.getString("imageUri"))
was causing an error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Intent android.content.Intent.putExtra(java.lang.String, android.os.Parcelable)' on a null object reference
So I changed to the following:
intent.putExtra("imageUri", imageUri)
and
Uri uri = (Uri) getIntent().get("imageUri");
This solved the problem.
Like this?
public static void Test()
{
using (var image = Image.FromFile(@"c:\logo.png"))
using (var newImage = ScaleImage(image, 300, 400))
{
newImage.Save(@"c:\test.png", ImageFormat.Png);
}
}
public static Image ScaleImage(Image image, int maxWidth, int maxHeight)
{
var ratioX = (double)maxWidth / image.Width;
var ratioY = (double)maxHeight / image.Height;
var ratio = Math.Min(ratioX, ratioY);
var newWidth = (int)(image.Width * ratio);
var newHeight = (int)(image.Height * ratio);
var newImage = new Bitmap(newWidth, newHeight);
using (var graphics = Graphics.FromImage(newImage))
graphics.DrawImage(image, 0, 0, newWidth, newHeight);
return newImage;
}
I got this on Firefox (FF58). I fixed this with:
dom.moduleScripts.enabled
in about:config
Source: Import page on mozilla (See Browser compatibility)
type="module"
to your script tag where you import the js file<script type="module" src="appthatimports.js"></script>
./

, ../
or http://
before)import * from "./mylib.js"
For more examples, this blog post is good.
Be careful that when you using:
curl -H "Authorization: token_str" http://www.example.com
token_str
and Authorization
must be separated by white space, otherwise server-side will not get the HTTP_AUTHORIZATION
environment.
This is the most exhaustive answer so far and gets rid of the need for a $i
variable floating around. It is a combo of Kip and Gnarf's answers.
$array = array( 'cat' => 'meow', 'dog' => 'woof', 'cow' => 'moo', 'computer' => 'beep' );
foreach( array_keys( $array ) as $index=>$key ) {
// display the current index + key + value
echo $index . ':' . $key . $array[$key];
// first index
if ( $index == 0 ) {
echo ' -- This is the first element in the associative array';
}
// last index
if ( $index == count( $array ) - 1 ) {
echo ' -- This is the last element in the associative array';
}
echo '<br>';
}
Hope it helps someone.
With OpenSSL you can convert pfx to Apache compatible format with next commands:
openssl pkcs12 -in domain.pfx -clcerts -nokeys -out domain.cer
openssl pkcs12 -in domain.pfx -nocerts -nodes -out domain.key
First command extracts public key to domain.cer
.
Second command extracts private key to domain.key
.
Update your Apache configuration file with:
<VirtualHost 192.168.0.1:443>
...
SSLEngine on
SSLCertificateFile /path/to/domain.cer
SSLCertificateKeyFile /path/to/domain.key
...
</VirtualHost>
Maybe something like this:
import matplotlib.pyplot
import pylab
x = [1,2,3,4]
y = [3,4,8,6]
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
EDIT:
Let me see if I understand you correctly now:
You have:
test1 | test2 | test3
test3 | 1 | 0 | 1
test4 | 0 | 1 | 0
test5 | 1 | 1 | 0
Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.
Let's say you results are stored in a 2-D list:
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
We want to transform them into two variables so we are able to plot them.
And I believe this code will give you what you are looking for:
import matplotlib
import pylab
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
x = []
y = []
for ind_1, sublist in enumerate(results):
for ind_2, ele in enumerate(sublist):
if ele == 1:
x.append(ind_1)
y.append(ind_2)
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
Notice that I do need to import pylab
, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.
@basarat's answer was great. Here is simplified but a little bit extended example you can use:
export type TMyEnumType = 'value1'|'value2';
export class MyEnumType {
static VALUE1: TMyEnumType = 'value1';
static VALUE2: TMyEnumType = 'value2';
}
console.log(MyEnumType.VALUE1); // 'value1'
const variable = MyEnumType.VALUE2; // it has the string value 'value2'
switch (variable) {
case MyEnumType.VALUE1:
// code...
case MyEnumType.VALUE2:
// code...
}
Basically in java, continue is a statement. So continue statement is normally used with the loops to skip the current iteration.
For how and when it is used in java, refer link below. It has got explanation with example.

Using Android studio 1.5.1 i got the following warnings:
Call requires API level 16 (current min is 9): android.view.View#setBackground
and the complaints about deprecation
'setBackgroundDrawable(android.graphics.drawable.Drawable)' is deprecated
Using this format, i got rid of both:
if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN) {
//noinspection deprecation
layout.setBackgroundDrawable(drawable);
} else {
layout.setBackground(drawable);
}
Combining answers https://stackoverflow.com/a/8462/1037948 (declaration via bit-shifting) and https://stackoverflow.com/a/9117/1037948 (using combinations in declaration) you can bit-shift previous values rather than using numbers. Not necessarily recommending it, but just pointing out you can.
Rather than:
[Flags]
public enum Options : byte
{
None = 0,
One = 1 << 0, // 1
Two = 1 << 1, // 2
Three = 1 << 2, // 4
Four = 1 << 3, // 8
// combinations
OneAndTwo = One | Two,
OneTwoAndThree = One | Two | Three,
}
You can declare
[Flags]
public enum Options : byte
{
None = 0,
One = 1 << 0, // 1
// now that value 1 is available, start shifting from there
Two = One << 1, // 2
Three = Two << 1, // 4
Four = Three << 1, // 8
// same combinations
OneAndTwo = One | Two,
OneTwoAndThree = One | Two | Three,
}
Confirming with LinqPad:
foreach(var e in Enum.GetValues(typeof(Options))) {
string.Format("{0} = {1}", e.ToString(), (byte)e).Dump();
}
Results in:
None = 0
One = 1
Two = 2
OneAndTwo = 3
Three = 4
OneTwoAndThree = 7
Four = 8
How about alias gcc99= gcc -std=c99
?
You've started right - now you just need to fill the each student
structure in the array:
struct student
{
public int s_id;
public String s_name, c_name, dob;
}
class Program
{
static void Main(string[] args)
{
student[] arr = new student[4];
for(int i = 0; i < 4; i++)
{
Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
arr[i].s_id = Int32.Parse(Console.ReadLine());
arr[i].s_name = Console.ReadLine();
arr[i].c_name = Console.ReadLine();
arr[i].s_dob = Console.ReadLine();
}
}
}
Now, just iterate once again and write these information to the console. I will let you do that, and I will let you try to make program to take any number of students, and not just 4.
On Angular 6, I access parent properties by injecting the parent via constructor. Not the best solution but it works:
constructor(@Optional() public parentComponentInjectionObject: ParentComponent){
// And access like this:
parentComponentInjectionObject.thePropertyYouWantToAccess;
}
In Javascript method names are camel case, so it's replace
, not Replace
:
$scope.newString = oldString.replace("stackover","NO");
Note that contrary to how the .NET Replace
method works, the Javascript replace
method replaces only the first occurrence if you are using a string as first parameter. If you want to replace all occurrences you need to use a regular expression so that you can specify the global (g) flag:
$scope.newString = oldString.replace(/stackover/g,"NO");
See this example.
The character set is part of the locale, which is determined by the value of NLS_LANG
. As the documentation makes clear this is an operating system variable:
NLS_LANG
is set as an environment variable on UNIX platforms.NLS_LANG
is set in the registry on Windows platforms.
Now we can use ALTER SESSION
to change the values for a couple of locale elements, NLS_LANGUAGE and NLS_TERRITORY. But not, alas, the character set. The reason for this discrepancy is - I think - that the language and territory simply effect how Oracle interprets the stored data, e.g. whether to display a comma or a period when displaying a large number. Wheareas the character set is concerned with how the client application renders the displayed data. This information is picked up by the client application at startup time, and cannot be changed from within.
subprocess.Popen
takes a cwd
argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'
), or use r'd:\test\local'
so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t
part will be translated to a tab.
So, your new line should look like:
subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')
To use your Python script path as cwd, import os
and define cwd using this:
os.path.dirname(os.path.realpath(__file__))
1) PYTHONPATH
is an environment variable which you can set to add additional directories where python will look for modules and packages. e.g.:
# make python look in the foo subdirectory of your home directory for
# modules and packages
export PYTHONPATH=${PYTHONPATH}:${HOME}/foo
Here I use the sh
syntax. For other shells (e.g. csh
,tcsh
), the syntax would be slightly different. To make it permanent, set the variable in your shell's init file (usually ~/.bashrc).
2) Ubuntu comes with python already installed. There may be reasons for installing other (independent) python versions, but I've found that to be rarely necessary.
3) The folder where your modules live is dependent on PYTHONPATH
and where the directories were set up when python was installed. For the most part, the installed stuff you shouldn't care about where it lives -- Python knows where it is and it can find the modules. Sort of like issuing the command ls
-- where does ls
live? /usr/bin
? /bin
? 99% of the time, you don't need to care -- Just use ls
and be happy that it lives somewhere on your PATH
so the shell can find it.
4) I'm not sure I understand the question. 3rd party modules usually come with install instructions. If you follow the instructions, python should be able to find the module and you shouldn't have to care about where it got installed.
5) Configure PYTHONPATH
to include the directory where your module resides and python will be able to find your module.

MySQL has a concept of user-defined variables.
They are loosely typed variables that may be initialized somewhere in a session and keep their value until the session ends.
They are prepended with an @
sign, like this: @var
You can initialize this variable with a SET
statement or inside a query:
SET @var = 1
SELECT @var2 := 2
When you develop a stored procedure in MySQL, you can pass the input parameters and declare the local variables:
DELIMITER //
CREATE PROCEDURE prc_test (var INT)
BEGIN
DECLARE var2 INT;
SET var2 = 1;
SELECT var2;
END;
//
DELIMITER ;
These variables are not prepended with any prefixes.
The difference between a procedure variable and a session-specific user-defined variable is that a procedure variable is reinitialized to NULL
each time the procedure is called, while the session-specific variable is not:
CREATE PROCEDURE prc_test ()
BEGIN
DECLARE var2 INT DEFAULT 1;
SET var2 = var2 + 1;
SET @var2 = @var2 + 1;
SELECT var2, @var2;
END;
SET @var2 = 1;
CALL prc_test();
var2 @var2
--- ---
2 2
CALL prc_test();
var2 @var2
--- ---
2 3
CALL prc_test();
var2 @var2
--- ---
2 4
As you can see, var2
(procedure variable) is reinitialized each time the procedure is called, while @var2
(session-specific variable) is not.
(In addition to user-defined variables, MySQL also has some predefined "system variables", which may be "global variables" such as @@global.port
or "session variables" such as @@session.sql_mode
; these "session variables" are unrelated to session-specific user-defined variables.)
Try the following.
$d = [datetime](Get-ItemProperty -Path $source -Name LastWriteTime).lastwritetime
This is part of the item property weirdness. When you run Get-ItemProperty it does not return the value but instead the property. You have to use one more level of indirection to get to the value.
Using absolute
as position
is not responsive + mobile friendly. I would suggest using a div
with a background-image
and then placing text in the div
will place text over the image. Depending on your html, you might need to use height
with vh
value
It seems that MacPorts could be installed in El Capitan right now: https://www.macports.org/install.php Then you probably can install gdb by link you mentioned.
<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;
echo date("H:i", $elapsed);
?>
I just want to add one important thing you can do with a forwarded class not mentioned in the answer of Luc Touraille.
What you can do with an incomplete type:
Define functions or methods which accept/return pointers/references to the incomplete type and forward that pointers/references to another function.
void f6(X*) {}
void f7(X&) {}
void f8(X* x_ptr, X& x_ref) { f6(x_ptr); f7(x_ref); }
A module can pass through an object of a forward declared class to another module.
I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.
I changed the line
.ui-helper-hidden-accessible { position: absolute !important; clip: rect(1px 1px 1px 1px); clip: rect(1px,1px,1px,1px); }
to
.ui-helper-hidden-accessible { position: absolute !important; }
and everything works now. Otherwise try upping the z-index as Soldierflup suggested.
// dict is Dictionary<string, Foo>
Foo[] foos = new Foo[dict.Count];
dict.Values.CopyTo(foos, 0);
// or in C# 3.0:
var foos = dict.Values.ToArray();
The compiler doesn't know that Environment.Exit() does not return. Why not just "return" from Main()?
Yes, you can use jQuery's attribute selector for that.
var linksToGoogle = $('a[href="http://google.com"]');
Alternatively, if your interest is rather links starting with a certain URL, use the attribute-starts-with selector:
var allLinksToGoogle = $('a[href^="http://google.com"]');
The python error says that wordInput
is not an iterable -> it is of NoneType.
If you print wordInput
before the offending line, you will see that wordInput
is None
.
Since wordInput
is None
, that means that the argument passed to the function is also None
. In this case word
. You assign the result of pickEasy
to word
.
The problem is that your pickEasy
function does not return anything. In Python, a method that didn't return anything returns a NoneType.
I think you wanted to return a word
, so this will suffice:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
I mean, why not a p/invoke method?
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
public class AppInfo
{
[DllImport("kernel32.dll", CharSet = CharSet.Auto, ExactSpelling = false)]
private static extern int GetModuleFileName(HandleRef hModule, StringBuilder buffer, int length);
private static HandleRef NullHandleRef = new HandleRef(null, IntPtr.Zero);
public static string StartupPath
{
get
{
StringBuilder stringBuilder = new StringBuilder(260);
GetModuleFileName(NullHandleRef, stringBuilder, stringBuilder.Capacity);
return Path.GetDirectoryName(stringBuilder.ToString());
}
}
}
You would use it just like the Application.StartupPath:
Console.WriteLine("The path to this executable is: " + AppInfo.StartupPath + "\\" + System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe");
One can use invisible iframes to get the cookies. Let's say there are two domains, a.com and b.com. For the index.html of domain a.com one can add (notice height=0 width=0):
<iframe height="0" id="iframe" src="http://b.com" width="0"></iframe>
That way your website will get b.com cookies assuming that http://b.com sets the cookies.
The next thing would be manipulating the site inside the iframe through JavaScript. The operations inside iframe may become a challenge if one doesn't own the second domain. But in case of having access to both domains referring the right web page at the src of iframe should give the cookies one would like to get.
You can use MATLAB-style tic
-toc
functions, if you prefer. See this other SO question
The way a cherry-pick works is by taking the diff a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying it to your current branch.
So, if a commit has two or more parents, it also represents two or more diffs - which one should be applied?
You're trying to cherry pick fd9f578
, which was a merge with two parents. So you need to tell the cherry-pick command which one against which the diff should be calculated, by using the -m
option. For example, git cherry-pick -m 1 fd9f578
to use parent 1 as the base.
I can't say for sure for your particular situation, but using git merge
instead of git cherry-pick
is generally advisable. When you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m
into that one commit. You lose all their history, and glom together all their diffs. Your call.
You can write a simple castMethod like the one below.
private <T> T castObject(Class<T> clazz, Object object) {
return (T) object;
}
In your method you should be using it like
public ConnectParams(HashMap<String,Object> object) {
for (Map.Entry<String, Object> entry : object.entrySet()) {
try {
Field f = this.getClass().getField(entry.getKey());
f.set(this, castObject(entry.getValue().getClass(), entry.getValue()); /* <= CASTING PROBLEM */
} catch (NoSuchFieldException ex) {
log.error("did not find field '" + entry.getKey() + '"');
} catch (IllegalAccessException ex) {
log.error(ex.getMessage());
}
}
}
import/export
is now doing the job with ES6. I still tend to prefix not exported functions with _
if most of my functions are exported.
If you export only a class (like in angular projects), it's not needed at all.
export class MyOpenClass{
open(){
doStuff()
this._privateStuff()
return close();
}
_privateStuff() { /* _ only as a convention */}
}
function close(){ /*... this is really private... */ }
input[type="checkbox"] {
/* your style */
}
But this will only work for browsers except IE7 and below, for those you will have to use a class.
For MacOS Maveriks (10.9 and perhaps later versions too), Apache Ant does not come bundled with the operating system and so must be installed manually. You can use brew to easily install ant. Simply execute the following command in a terminal window to install brew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
It's a medium sized download which took me 10min to download and install. Just follow the process which involves installing various components. If you already have brew installed, make sure it's up to date by executing:
brew update
Once installed you can simply type:
brew install ant
Ant is now installed and available through the "ant" command in the terminal.
To test the installation, just type "ant -version
" into a terminal window. You should get the following output:
Apache Ant(TM) version X.X.X compiled on MONTH DAY YEAR
If you are getting errors installing Brew, try uninstalling first using the command:
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

Technically, Node.js isn't proper JavaScript as we know it, since there isn't a Document Object Model (DOM). For instance, JavaScript scripts that run in the browser will not work. At all. The solution would be to run JavaScript with a headless browser. Fortunately there is a project still active: Mozilla Firefox has a headless mode.
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Headless_mode
$ /Applications/Firefox.app/Contents/MacOS/firefox -headless index.html
*** You are running in headless mode.
You can't have optional arguments that default to a certain value in Java. The nearest thing to what you are talking about is java varargs whereby you can pass an arbitrary number of arguments (of the same type) to a method.
In view file (HTML or EJS)

}

What about this:
var txt="";

txt += nyc[x];

If you don't want the weekends to appear at all, simply:
CSS
th.ui-datepicker-week-end,
td.ui-datepicker-week-end {
display: none;
}
You will find the siblings() and parent() methods useful here.
// assuming A1 is clicked
$('div a').click(function(e) {
$(this); // A1
$(this).parent(); // the div containing A1
$(this).siblings(); // A2 and A3
});
Combining those methods with andSelf() will let you manipulate any combination of those elements you want.
Edit: The comment left by Mark regarding event delegation on Shog9's answer is a very good one. The easiest way to accomplish this in jQuery would be by using the live() method.
// assuming A1 is clicked
$('div a').live('click', function(e) {
$(this); // A1
$(this).parent(); // the div containing A1
$(this).siblings(); // A2 and A3
});
I think it actually binds the event to the root element, but the effect is that same. Not only is it more flexible, it also improves performance in a lot of cases. Just be sure to read the documentation to avoid any gotchas.
The command line utility nmap can do this too:
nmap -sP 192.168.1.*
Before you begin to curse your application you need to check this:
Is your application the only one using that instance of SQL Server. a. If the answer to that is NO then you need to investigate how the other applications are consuming resources on your SQl Server.run b. If the answer is yes then you must investigate your application.
Run SQL Server Profiler and check what activity is happening in other applications (1a) using SQL Server and check your application as well (1b).
If indeed your application is starved off of resources then you need to make farther investigations. For more read on this http://sqlserverplanet.com/troubleshooting/sql-server-slowness

EDIT: This answer is old and likely out of date. Just a heads up so it doesn't lead folks astray. I no longer use Angular so I'm not in a good position to make improvements.
It's actually pretty good logic but you can simplify things a bit.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.model = { name: 'World' };
$scope.name = "Felipe";
});
app.directive('myDirective', function($compile) {
return {
restrict: 'AE', //attribute or element
scope: {
myDirectiveVar: '=',
//bindAttr: '='
},
template: '<div class="some">' +
'<input ng-model="myDirectiveVar"></div>',
replace: true,
//require: 'ngModel',
link: function($scope, elem, attr, ctrl) {
console.debug($scope);
//var textField = $('input', elem).attr('ng-model', 'myDirectiveVar');
// $compile(textField)($scope.$parent);
}
};
});
<body ng-controller="MainCtrl">
This scope value <input ng-model="name">
<my-directive my-directive-var="name"></my-directive>
</body>
.some {
border: 1px solid #cacaca;
padding: 10px;
}
You can see it in action with this Plunker.
Here's what I see:
EDIT As mentioned by Mark in his comment, there's no reason that you can't use ng-model, just to keep with convention.
In general, your directives should use the isolated scope (which you did correctly) and use the '=' type scope if you want a value in your directive to always map to a value in the parent scope.
Here's an idea. Imagine an HSV cylinder
Define the upper and lower limits you want for the Brightness and Saturation. This defines a square cross section ring within the space.
Now, scatter N points randomly within this space.
Then apply an iterative repulsion algorithm on them, either for a fixed number of iterations, or until the points stabilise.
Now you should have N points representing N colours that are about as different as possible within the colour space you're interested in.

For same error code i had quite different reason, I'm sharing here to help
I had web api action like below
public IHttpActionResult GetBooks (int id)
I changed the method to accept two parameters category and author so i changed the parameters as below, i also put the attribute [Httppost]
public IHttpActionResult GetBooks (int category, int author)
I also changed ajax options like below and at this point i start getting error 405 method not allowed
var options = {
url: '/api/books/GetBooks',
type: 'POST',
dataType: 'json',
cache: false,
traditional: true,
data: {
category: 1,
author: 15
}
}
When i created class for web api action parameters like below error was gone
public class BookParam
{
public int Category { get; set; }
public int Author { get; set; }
}
public IHttpActionResult GetBooks (BookParam param)
In my case, Swift Mailer couldn't help either. I found a solution here: http://forum.powweb.com/showthread.php?t=73406 - so after EHLO command one needs to send STARTTLS command, enabling cryptography with stream_socket_enable_crypto( $connection, true, STREAM_CRYPTO_METHOD_TLS_CLIENT );
and again EHLO command. Only this allowed me to send emails with my "stubborn" SMTP server.
For shorter JavaScript-Code use this:
myApp.service('userService', [
'$q', function($q) {
this.initialized = $q.when();
this.user = {
access: false
};
this.isAuthenticated = function() {
this.user = {
first_name: 'First',
last_name: 'Last',
email: '[email protected]',
access: 'institution'
};
return this.initialized;
};
}
]);
You know that you loose the binding to userService.user by overwriting it with a new object instead of setting only the objects properties?
Here is what I mean as a example of my plnkr.co example code (Working example: http://plnkr.co/edit/zXVcmRKT1TmiBCDL4GsC?p=preview):
angular.module('myApp', []).service('userService', [
'$http', '$q', '$rootScope', '$location', function ($http, $q, $rootScope, $location) {
this.initialized = $q.when(null);
this.user = {
access: false
};
this.isAuthenticated = function () {
this.user.first_name = 'First';
this.user.last_name = 'Last';
this.user.email = '[email protected]';
this.user.access = 'institution';
return this.initialized;
};
}]);
angular.module('myApp').controller('myCtrl', ['$scope', 'userService', function ($scope, userService) {
$scope.user = userService.user;
$scope.callUserService = function () {
userService.isAuthenticated().then(function () {
$scope.thencalled = true;
});
};
}]);
Add this in your js file:
$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
and add this to your server file:
$params = json_decode(file_get_contents('php://input'), true);
That should work.
You could try using Texter and create something unlikely like:
./p , triggered by space and replacing the text with %c
I just tested it and it works fine. The only gotcha is to use a rare sequence, as Texter cannot restrict this to just cmd.
There are probably other utilities of this kind which could work, and even AutoHotKey, upon which Texter is built could do it better, but Texter is easy :-)
The key checks for FAST REFRESH includes the following:
1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.
No 3 is easy to miss and worth highlighting here
For me the problem was a configuration file that was missing an Element.
This can be done using ServerSocket, same as on JavaSE. This class is available on Android. android.permission.INTERNET
is required.
The only more tricky part, you need a separate thread wait on the ServerSocket, servicing sub-sockets that come from its accept
method. You also need to stop and resume this thread as needed. The simplest approach seems to kill the waiting thread by closing the ServerSocket.
If you only need a server while your activity is on the top, starting and stopping ServerSocket thread can be rather elegantly tied to the activity life cycle methods. Also, if the server has multiple users, it may be good to service requests in the forked threads. If there is only one user, this may not be necessary.
If you need to tell the user on which IP is the server listening,use NetworkInterface.getNetworkInterfaces(), this question may tell extra tricks.
Finally, here there is possibly the complete minimal Android server that is very short, simple and may be easier to understand than finished end user applications, recommended in other answers.
You can use the minus operator or Math.abs. These work for all negative integers EXCEPT for Integer.MIN_VALUE! If you do 0 - MIN_VALUE the answer is still MIN_VALUE.
there is a soap config section in your php.ini file, which control the wsdl access cache, may be shown as:
[soap]
; Enables or disables WSDL caching feature.
soap.wsdl_cache_enabled=1 ;
Sets the directory name where SOAP extension will put cache files.
soap.wsdl_cache_dir="/tmp"
; (time to live) Sets the number of second while cached file will be used ; instead of original one.
soap.wsdl_cache_ttl=86400
if wsdl file cache is enabled, it may cause this problem when changing wsdl URI in php code.
in this example, you can just delete file start with wsdl-
under /tmp
directory.
or you just set soap.wsdl_cache_enabled=0;
and soap.wsdl_cache_ttl=0;
PHP will fetch the wsdl file every-time you visit the page.

Sometimes \n\r etc not work, here to figure it out, what your actually regular expression should be.
Advantage of this trick: If you want to replace in multiple file at once, you must need this method. Above will not work...
You can't wait()
on an object unless the current thread owns that object's monitor. To do that, you must synchronize
on it:
class Runner implements Runnable
{
public void run()
{
try
{
synchronized(Main.main) {
Main.main.wait();
}
} catch (InterruptedException e) {}
System.out.println("Runner away!");
}
}
The same rule applies to notify()
/notifyAll()
as well.
The Javadocs for wait()
mention this:
This method should only be called by a thread that is the owner of this object's monitor. See the
Throws:notify
method for a description of the ways in which a thread can become the owner of a monitor.
IllegalMonitorStateException
– if the current thread is not the owner of this object's monitor.
And from notify()
:
A thread becomes the owner of the object's monitor in one of three ways:
- By executing a synchronized instance method of that object.
- By executing the body of a
synchronized
statement that synchronizes on the object.- For objects of type
Class
, by executing a synchronized static method of that class.
Using this code it will be responsive also.

In handlebar version 3.0 onwards,
{{#each users as |user userId|}}
Id: {{userId}} Name: {{user.name}}
{{/each}}
In this particular example, user will have the same value as the current context and userId will have the index value for the iteration. Refer - http://handlebarsjs.com/block_helpers.html in block helpers section
You need to make sure that the value you pass to the directory
argument is an absolute path, corrected for the current location of your application.
The best way to do this is to configure UPLOAD_FOLDER
as a relative path (no leading slash), then make it absolute by prepending current_app.root_path
:
@app.route('/uploads/<path:filename>', methods=['GET', 'POST'])
def download(filename):
uploads = os.path.join(current_app.root_path, app.config['UPLOAD_FOLDER'])
return send_from_directory(directory=uploads, filename=filename)
It is important to reiterate that UPLOAD_FOLDER
must be relative for this to work, e.g. not start with a /
.
A relative path could work but relies too much on the current working directory being set to the place where your Flask code lives. This may not always be the case.

</form>
_x000D_
Well when creating this example I somehow got a little confused. "ValueText" vs >Current NodeText< Isn't .val()
supposed to run on the data of the value attribute? Anyway I and you me may clear up this sooner or later.
However the point for now is:
When working with form data use .val().
When dealing with the mostly read only data in between the tag use .text() or .append() to append text.
I'm successfully using the following to update options dynamically:
$control.select2('destroy').empty().select2({data: [{id: 1, text: 'new text'}]});
In my case it was because I was using the alpha version of support library 28. Looks like Google marks these pre release versions as testOnly. If you really want to release like this (for instance, you want to push an internal beta like I did), you can add this line to your gradle.properties file:
android.injected.testOnly=false
After reading Sime Vidas's answer, I searched more and found a very straight-forward and easy-to-understand explanation in the angular docs.
HTML attribute vs. DOM property
-------------------------------
Attributes are defined by HTML. Properties are defined by the DOM (Document Object Model).
A few HTML attributes have 1:1 mapping to properties.
id
is one example.Some HTML attributes don't have corresponding properties.
colspan
is one example.Some DOM properties don't have corresponding attributes.
textContent
is one example.Many HTML attributes appear to map to properties ... but not in the way you might think!
That last category is confusing until you grasp this general rule:
Attributes initialize DOM properties and then they are done. Property values can change; attribute values can't.
For example, when the browser renders
<input type="text" value="Bob">
, it creates a corresponding DOM node with avalue
property initialized to "Bob".When the user enters "Sally" into the input box, the DOM element
value
property becomes "Sally". But the HTMLvalue
attribute remains unchanged as you discover if you ask the input element about that attribute:input.getAttribute('value')
returns "Bob".The HTML attribute
value
specifies the initial value; the DOMvalue
property is the current value.
The
disabled
attribute is another peculiar example. A button'sdisabled
property isfalse
by default so the button is enabled. When you add thedisabled
attribute, its presence alone initializes the button'sdisabled
property totrue
so the button is disabled.Adding and removing the
disabled
attribute disables and enables the button. The value of the attribute is irrelevant, which is why you cannot enable a button by writing<button disabled="false">Still Disabled</button>.
Setting the button's
disabled
property disables or enables the button. The value of the property matters.The HTML attribute and the DOM property are not the same thing, even when they have the same name.
Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:
---
# this is just to avoid a call to |default on each iteration
- set_fact:
postconf_d: {}
- name: 'get postfix default configuration'
command: 'postconf -d'
register: command
# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
set_fact:
postconf_d: >
{{
postconf_d |
combine(
dict([ item.partition('=')[::2]|map('trim') ])
)
with_items: command.stdout_lines
This will give the following output (stripped for the example):
"postconf_d": {
"alias_database": "hash:/etc/aliases",
"alias_maps": "hash:/etc/aliases, nis:mail.aliases",
"allow_min_user": "no",
"allow_percent_hack": "yes"
}
Going even further, parse the lists in the 'value':
- name: 'set postfix default configuration as fact'
set_fact:
postconf_d: >-
{% set key, val = item.partition('=')[::2]|map('trim') -%}
{% if ',' in val -%}
{% set val = val.split(',')|map('trim')|list -%}
{% endif -%}
{{ postfix_default_main_cf | combine({key: val}) }}
with_items: command.stdout_lines
...
"postconf_d": {
"alias_database": "hash:/etc/aliases",
"alias_maps": [
"hash:/etc/aliases",
"nis:mail.aliases"
],
"allow_min_user": "no",
"allow_percent_hack": "yes"
}
A few things to notice:
in this case it's needed to "trim" everything (using the >-
in YAML and -%}
in Jinja), otherwise you'll get an error like:
FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\" {u'...
obviously the {% if ..
is far from bullet-proof
in the postfix case, val.split(',')|map('trim')|list
could have been simplified to val.split(', ')
, but I wanted to point out the fact you will need to |list
otherwise you'll get an error like:
"|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
Hope this can help.

Simplest solution: Use Unicode Characters
No expression
or other packages needed.
Not sure if this is a newer feature for ggplot, but it works.
It also makes it easy to mix Greek and regular text (like adding '*' to the ticks)
Just use unicode characters within the text string. seems to work well for all options I can think of. Edit: previously it did not work in facet labels. This has apparently been fixed at some point.
library(ggplot2)
ggplot(mtcars,
aes(mpg, disp, color=factor(gear))) +
geom_point() +
labs(title="Title (\u03b1 \u03a9)", # works fine
x= "\u03b1 \u03a9 x-axis title", # works fine
y= "\u03b1 \u03a9 y-axis title", # works fine
color="\u03b1 \u03a9 Groups:") + # works fine
scale_x_continuous(breaks = seq(10, 35, 5),
labels = paste0(seq(10, 35, 5), "\u03a9*")) + # works fine; to label the ticks

I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:
1) I set up a form so I can use a POST method.
2) When the user is done drawing, he can click the "Save" button.
3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.
document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();
4) When the form is submited I have this small php script:
<?php
$upload_dir = somehow_get_upload_dir(); //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>
You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:
clean:
@if [ "test" = "test" ]; then\
echo "Hello world";\
fi
Note that the closing ";" and "\" are necessary.

It is possible to code even the solution like this for example :
var loop = function(i, data, callback) {
if (i < data.length) {
//TODO("SELECT * FROM stackoverflowUsers;", function(res) {
//data[i].meta = res;
console.log(i, data[i].title);
return loop(i+1, data, errors, callback);
//});
} else {
return callback(data);
}
};
loop(0, [{"title": "hello"}, {"title": "world"}], function(data) {
console.log("DONE\n"+data);
});
On the other hand, it is much slower than a "for".
Otherwise, the excellent Async library can do this: https://caolan.github.io/async/docs.html#each
This is the best and easy way to import font from google and
this is also a standard method to import font
Paste this code on your index page or on header
<link href='http://fonts.googleapis.com/css?family=Oswald:400,300,700' rel='stylesheet' type='text/css'>
other method is to import on css like this:
@import url(http://fonts.googleapis.com/css?family=Oswald:400,300,700);
on your Css file as this code
body {
font-family: 'Oswald', sans-serif !important;
}
Note : The @import code line will be the first lines in your css file (style.css, etc.css). They can be used in any of the .css files and should always be the first line in these files. The following is an example:
Unsorted vector:
if (std::find(v.begin(), v.end(),value)!=v.end())
...
Sorted vector:
if (std::binary_search(v.begin(), v.end(), value)
...
P.S. may need to include <algorithm>

What is the difference between them?
Image: the generic Linux kernel binary image file.
zImage: a compressed version of the Linux kernel image that is self-extracting.
uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.
Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:
Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.
(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)
Which type of kernel image do I have to use?
You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.
ADDENDUM
I know that u-boot needs a kernel in uImage format.
That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.
(A lot of theoretical and conceptual explanation has been given above)
Below are some of the practical examples when I used static_cast, dynamic_cast, const_cast, reinterpret_cast.
(Also referes this to understand the explaination : http://www.cplusplus.com/doc/tutorial/typecasting/)
static_cast :
OnEventData(void* pData)
{
......
// pData is a void* pData,
// EventData is a structure e.g.
// typedef struct _EventData {
// std::string id;
// std:: string remote_id;
// } EventData;
// On Some Situation a void pointer *pData
// has been static_casted as
// EventData* pointer
EventData *evtdata = static_cast<EventData*>(pData);
.....
}
dynamic_cast :
void DebugLog::OnMessage(Message *msg)
{
static DebugMsgData *debug;
static XYZMsgData *xyz;
if(debug = dynamic_cast<DebugMsgData*>(msg->pdata)){
// debug message
}
else if(xyz = dynamic_cast<XYZMsgData*>(msg->pdata)){
// xyz message
}
else/* if( ... )*/{
// ...
}
}
const_cast :
// *Passwd declared as a const
const unsigned char *Passwd
// on some situation it require to remove its constness
const_cast<unsigned char*>(Passwd)
reinterpret_cast :
typedef unsigned short uint16;
// Read Bytes returns that 2 bytes got read.
bool ByteBuffer::ReadUInt16(uint16& val) {
return ReadBytes(reinterpret_cast<char*>(&val), 2);
}
The answers so far only consider the worth of have a null
key, but the question also asks about any number of null values
.
The benefit of storing the value null
against a key in a HashMap is the same as in databases, etc - you can record a distinction between having a value that is empty (e.g. string ""), and not having a value at all (null).
You can just put a small script and then check. It won't allow you to visit previous page.
This is done in JavaScript.
<script type="text/javascript">
function preventbackbutton() { window.history.forward(); }
setTimeout("preventbackbutton()", 0);
window.onunload = function () { null };
</script>
The window.onunload function fires when you try to visit back or previous page through browser.

If you are using eclipse, you should modify the context.xml, from the server project created in your eclipse package explorer. When using tomcat in eclipse it is the only one valid, the others are ignored or overwriten
Using HTML5 mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your application (e.g. index.html). Requiring a <base>
tag is also important for this case, as it allows AngularJS to differentiate between the part of the url that is the application base and the path that should be handled by the application. For more information, see AngularJS Developer Guide - Using $location HTML5 mode Server Side.
When you have html5Mode enabled, the #
character will no longer be used in your urls. The #
symbol is useful because it requires no server side configuration. Without #
, the url looks much nicer, but it also requires server side rewrites. Here are some examples:
<VirtualHost *:80>
ServerName my-app
DocumentRoot /path/to/app
<Directory /path/to/app>
RewriteEngine on
# Don't rewrite files or directories
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
# Rewrite everything else to index.html to allow html5 state links
RewriteRule ^ index.html [L]
</Directory>
</VirtualHost>
server {
server_name my-app;
index index.html;
root /path/to/app;
location / {
try_files $uri $uri/ /index.html;
}
}

you can use the return
statement without any parameter to exit a function
def foo(element):
do something
if check is true:
do more (because check was succesful)
else:

do much much more...
or raise an exception if you want to be informed of the problem

else:
raise Exception("cause of the problem")
do much much more...
You can't modify the keys nor the values directly in a ForEach, but you can modify their members. E.g., this should work:
public class State {
public int Value;
}
...
Dictionary<string, State> colStates = new Dictionary<string,State>();
int OtherCount = 0;
foreach(string key in colStates.Keys)
{
double Percent = colStates[key].Value / TotalCount;
if (Percent < 0.05)
{
OtherCount += colStates[key].Value;
colStates[key].Value = 0;
}
}
colStates.Add("Other", new State { Value = OtherCount } );
TLDR:First determine where in the pipeline you're getting the error from (scroll looking for screenshots of something that resembles your error), make changes to get something new, repeat.
If you are seeing the file located here...
%SystemDrive%\inetpub\custerr\\500.htm
...which generally looks like this:
...then you know you are seeing the currently configured error page in **IIS ** and you do NOT need to change the ASP.net customErrors setting, asp error detail setting, or "show friendly http errors" browser setting.
You may want to look at the above referenced path instead of trusting my screenshot just in case somebody changed it.
In this case, you are seeing the setting of <httpErrors> or in IIS Manager it's Error Pages --> Edit Feature Settings. The default for this is errorMode=DetailedLocalOnly at the server node level (as opposed to the site level) which means that while you will see this configured error page while remote, you should be able to log on locally to the server and see the full error which should look something like this:
You should have everything that you need at that point to fix the current error.
That leaves a couple of possibilities.
Change your site's httpErrors to "Detailed" so you can see it remotely. But if it doesn't work your error might already be a config error, see #3 immediately above. So you might be stuck with #4 or #5 and you're going to need somebody from your server team.
...and you expect to see something like this...
...then you need to change "Send errors to browser" to true in IIS Manager, under Site --> IIS --> ASP --> Debugging Properties
or this...
...you need to disable friendly errors in your browser or use fiddler's webview to look at the actual response vs what your browser chooses to show you.
If you see this...
...then custom errors is working but you don't have a custom error page (of course at this point were talking about .net and not classic asp). You need to change your customErrors tag in your web.config to RemoteOnly to view on the server, or Off to view remotely.
If you see something that is styled like your site, then custom errors is likely On or RemoteOnly and it's displaying the custom page (Views->Shared->Error.cshtml in MVC for example). That said, it is unlikely but possible that somebody changed the pages in IIS for httpErrors so see the first section on that.

According to the ALTER DATABASE SET documentation, there is still a possibility that after setting a database to SINGLE_USER mode you won't be able to access that database:
Before you set the database to SINGLE_USER, verify the AUTO_UPDATE_STATISTICS_ASYNC option is set to OFF. When set to ON, the background thread used to update statistics takes a connection against the database, and you will be unable to access the database in single-user mode.
So, a complete script to drop the database with existing connections may look like this:
DECLARE @dbId int
DECLARE @isStatAsyncOn bit
DECLARE @jobId int
DECLARE @sqlString nvarchar(500)
SELECT @dbId = database_id,
@isStatAsyncOn = is_auto_update_stats_async_on
FROM sys.databases
WHERE name = 'db_name'
IF @isStatAsyncOn = 1
BEGIN
ALTER DATABASE [db_name] SET AUTO_UPDATE_STATISTICS_ASYNC OFF
-- kill running jobs
DECLARE jobsCursor CURSOR FOR
SELECT job_id
FROM sys.dm_exec_background_job_queue
WHERE database_id = @dbId
OPEN jobsCursor
FETCH NEXT FROM jobsCursor INTO @jobId
WHILE @@FETCH_STATUS = 0
BEGIN
set @sqlString = 'KILL STATS JOB ' + STR(@jobId)
EXECUTE sp_executesql @sqlString
FETCH NEXT FROM jobsCursor INTO @jobId
END
CLOSE jobsCursor
DEALLOCATE jobsCursor
END
ALTER DATABASE [db_name] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DROP DATABASE [db_name]
Another way to accomplish this if you still have that issue is by doing the following :
Thanks, Sufian.
SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;
Just make sure that in the SELECT line you specify which table columns you are using, either by full reference, or by alias. Any of the following will work:
SELECT *
SELECT t1.*,t2.column2
SELECT A.table1.column1, t2.*
etc.

I don't think you should ever provide the False

test = df.sort_values(by='one', ascending = False)
The relational algebra allows interchangeability of the predicates in the WHERE
clause and the INNER JOIN
, so even INNER JOIN
queries with WHERE
clauses can have the predicates rearrranged by the optimizer so that they may already be excluded during the JOIN
process.
I recommend you write the queries in the most readable way possible.
Sometimes this includes making the INNER JOIN
relatively "incomplete" and putting some of the criteria in the WHERE
simply to make the lists of filtering criteria more easily maintainable.
For example, instead of:
SELECT *
FROM Customers c
INNER JOIN CustomerAccounts ca
ON ca.CustomerID = c.CustomerID
AND c.State = 'NY'
INNER JOIN Accounts a
ON ca.AccountID = a.AccountID
AND a.Status = 1
Write:
SELECT *
FROM Customers c
INNER JOIN CustomerAccounts ca
ON ca.CustomerID = c.CustomerID
INNER JOIN Accounts a
ON ca.AccountID = a.AccountID
WHERE c.State = 'NY'
AND a.Status = 1
But it depends, of course.

Answer in Swift:
Add delegate UIGestureRecognizerDelegate
to your UITableViewController.
Within UITableViewController:
override func viewDidLoad() {
super.viewDidLoad()
let longPressGesture:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: "handleLongPress:")
longPressGesture.minimumPressDuration = 1.0 // 1 second press
longPressGesture.delegate = self
self.tableView.addGestureRecognizer(longPressGesture)
}
And the function:
func handleLongPress(longPressGesture:UILongPressGestureRecognizer) {
let p = longPressGesture.locationInView(self.tableView)
let indexPath = self.tableView.indexPathForRowAtPoint(p)
if indexPath == nil {
print("Long press on table view, not row.")
}
else if (longPressGesture.state == UIGestureRecognizerState.Began) {
print("Long press on row, at \(indexPath!.row)")
}
}

I believe the best way to store Lat/Lng in MySQL is to have a POINT column (2D datatype) with a SPATIAL index.
CREATE TABLE `cities` (
`zip` varchar(8) NOT NULL,
`country` varchar (2) GENERATED ALWAYS AS (SUBSTRING(`zip`, 1, 2)) STORED,
`city` varchar(30) NOT NULL,
`centre` point NOT NULL,
PRIMARY KEY (`zip`),
KEY `country` (`country`),
KEY `city` (`city`),
SPATIAL KEY `centre` (`centre`)
) ENGINE=InnoDB;
INSERT INTO `cities` (`zip`, `city`, `centre`) VALUES
('CZ-10000', 'Prague', POINT(50.0755381, 14.4378005));
Try this
padding:8px;
overflow: hidden;
zoom: 1;
text-align: left;

font-family: "Trebuchet MS",Arial,Sans;
line-height: 24px;
color: black;
border-bottom: solid 1px #BBB;

This is full css.. Why you use padding:0 8px
, then override it with paddings? This is what you need...

In addition to the answers above. You can do it programmatically by implementing the TrustManager:
TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
@Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1)
throws CertificateException {}
@Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1)
throws CertificateException {}
}
};
SSLContext sc=null;
try {
sc = SSLContext.getInstance("SSL");
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
try {
sc.init(null, trustAllCerts, new java.security.SecureRandom());
} catch (KeyManagementException e) {
e.printStackTrace();
}
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
// Create all-trusting host name verifier
HostnameVerifier validHosts = new HostnameVerifier() {
@Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
};
// All hosts will be valid
HttpsURLConnection.setDefaultHostnameVerifier(validHosts);
However this is not a good practice for production.
This example on How to disable SSL certificat validation in Java contains a utility class you can copy in your project.
Use this one:
Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")
With rng.Validation
.Delete 'delete previous validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Formula1:="='" & ws.Name & "'!" & range1.Address
End With
Note that when you're using Dim range1, rng As range
, only rng
has type of Range
, but range1
is Variant
. That's why I'm using Dim range1 As Range, rng As Range
.
About meaning of parameters you can read is MSDN, but in short:
Type:=xlValidateList
means validation type, in that case you should select value from listAlertStyle:=xlValidAlertStop
specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.Operator:= xlBetween
is odd. It can be used only if two formulas are provided for validation.Formula1:="='" & ws.Name & "'!" & range1.Address
for list data validation provides address of list with values (in format =Sheet!A1:A5
)I needed to enable the JUnit plugin, after I linked my project with the jar files.
To enable the JUnit plugin, go to File->Settings, type "JUnit" in the search bar, and under "Plugins," check "JUnit.
vikingsteve's advice above will probably get the libraries linked right. Otherwise, open File->Project Structure, go to Libraries, hit the plus, and then browse to
C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 14.1.1\lib\
and add these jar files:
hamcrest-core-1.3.jar
junit-4.11.jar
junit.jar
JButton
has a model which answers these question:
isArmed()
, isPressed()
, isRollOVer()
etc. Hence you can ask the model for the answer you are seeking:
if(jButton1.getModel().isPressed())
System.out.println("the button is pressed");
This error will also occur if you call .ps1
file from a .bat
file and file path has spaces.
The fix is to make sure there are no spaces in the path of .ps1
file.
Both OpenJDK and Oracle JDK are created and maintained currently by Oracle only.
OpenJDK and Oracle JDK are implementations of the same Java specification passed the TCK (Java Technology Certification Kit).
Most of the vendors of JDK are written on top of OpenJDK by doing a few tweaks to [mostly to replace licensed proprietary parts / replace with more high-performance items that only work on specific OS] components without breaking the TCK compatibility.
Many vendors implemented the Java specification and got TCK passed. For example, IBM J9, Azul Zulu, Azul Zing, and Oracle JDK.
Almost every existing JDK is derived from OpenJDK.
As suggested by many, licensing is a change between JDKs.
Starting with JDK 11 accessing the long time support Oracle JDK/Java SE will now require a commercial license. You should now pay attention to which JDK you're installing as Oracle JDK without subscription could stop working. source
You mean fast enumeration? You question is very unclear.
A normal for loop would look a bit like this:
unsigned int i, cnt = [someArray count];
for(i = 0; i < cnt; i++)
{
// do loop stuff
id someObject = [someArray objectAtIndex:i];
}
And a loop with fast enumeration, which is optimized by the compiler, would look like this:
for(id someObject in someArray)
{
// do stuff with object
}
Keep in mind that you cannot change the array you are using in fast enumeration, thus no deleting nor adding when using fast enumeration
For those who are looking for java.lang.UnsatisfiedLinkError: no pdf_java in java.library.path
I was facing same exception; I tried everything and important things to make it work are:
It worked with tomcat 6.
In the database, there are two options:
I've used bytea columns with great success in the past storing 10+gb of images with thousands of rows. PG's TOAST functionality pretty much negates any advantage that blobs have. You'll need to include metadata columns in either case for filename, content-type, dimensions, etc.
I solved it by adding this to the /etc/profile - system wide (or to user local .profile, or _.bash_profile_):
# SSH-AGENT
#!/usr/bin/env bash
SERVICE='ssh-agent'
WHOAMI=`who am i |awk '{print $1}'`
if pgrep -u $WHOAMI $SERVICE >/dev/null
then
echo $SERVICE running.
else
echo $SERVICE not running.
echo starting
ssh-agent > ~/.ssh/agent_env
fi
. ~/.ssh/agent_env
This starts a new ssh-agent if not running for the current user, or re-sets the ssh-agent env parameter if running.
I realize this is an old post but as I just ran into the same issue and had trouble finding the answer I thought I'd add a bit.
So @hammar's answer is correct. Using push.default simple
is, in a way, like configuring tracking on your branches so you don't need to specify remotes and branches when pushing and pulling. The matching
option will push all branches to their corresponding counterparts on the default remote (which is the first one that was set up unless you've configured your repo otherwise).
One thing I hope others find useful in the future is that I was running Git 1.8 on OS X Mountain Lion and never saw this error. Upgrading to Mavericks is what suddenly made it show up (running git --version
will show git version 1.8.3.4 (Apple Git-47)
which I'd never seen until the update to the OS.
SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

Edit:
This one doesn't work in IE and opera, but seems to work for firefox, safari and chrome.
Try using a custom answer.
For example:
import org.mockito.Mockito;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
public class CustomAnswer implements Answer<Object> {
public Object answer(InvocationOnMock invocation) throws Throwable {
Answer<Object> answer = null;
if (isAbstract(invocation.getMethod().getModifiers())) {
answer = Mockito.RETURNS_DEFAULTS;
} else {
answer = Mockito.CALLS_REAL_METHODS;
}
return answer.answer(invocation);
}
}
It will return the mock for abstract methods and will call the real method for concrete methods.
If you look at the this code example (which works for Python 2 and 3) you'll see the function definition below which can extract
for an entire stack trace, whether or not there has been an exception:
def sentry_friendly_trace(get_last_exception=True):
try:
current_call = list(map(frame_trans, traceback.extract_stack()))
alert_frame = current_call[-4]
before_call = current_call[:-4]
err_type, err, tb = sys.exc_info() if get_last_exception else (None, None, None)
after_call = [alert_frame] if err_type is None else extract_all_sentry_frames_from_exception(tb)
return before_call + after_call, err, alert_frame
except:
return None, None, None
Of course, this function depends on the entire gist linked above, and in particular extract_all_sentry_frames_from_exception()
and frame_trans()
but the exception info extraction totals less than around 60 lines.
Hope that helps!
To print the names of all files in and below $dir of size 0:
find "$dir" -size 0
Note that not all implementations of find
will produce output by default, so you may need to do:
find "$dir" -size 0 -print
Two comments on the final loop in the question:
Rather than iterating over every other word in a string and seeing if the alternate values are zero, you can partially eliminate the issue you're having with whitespace by iterating over lines. eg:
printf '1 f1\n0 f 2\n10 f3\n' | while read size path; do
test "$size" -eq 0 && echo "$path"; done
Note that this will fail in your case if any of the paths output by ls contain newlines, and this reinforces 2 points: don't parse ls
, and have a sane naming policy that doesn't allow whitespace in paths.
Secondly, to output the data from the loop, there is no need to store the output in a variable just to echo
it. If you simply let the loop write its output to stdout, you accomplish the same thing but avoid storing it.
You can simply set the status code of the response to 200 like the following
public ActionResult SomeMethod(parameters...)
{
//others code here
...
Response.StatusCode = 200;
return YourObject;
}
PHP's config can be set in multiple places:
php.ini
(usually in /etc somewhere)php_value
)php.ini
(use the command php -i | grep memory_limit
to check the CLI conf)php_value
)ini_set()
)In PHPinfo's output, the "Master" value is the compiled-in default value, and the "Local" value is what's actually in effect. It can be either unchanged from the default, or overridden in any of the above locations.
Also note that PHP generally has different .ini files for command-line and webserver-based operation. Checking phpinfo()
from the command line will report different values than if you'd run it in a web-based script.
Since this question has been answered, another solution has been launched.
https://github.com/appjs/appjs
At the time of this writing, this is the end-all solution for packaging node.js apps through a stripped down chromium package compiled into an executable.
Edit: AppJS is no longer active, but itself suggests a fork called deskshell.
I add in myApp.java, after @SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
And changed
@SpringBootApplication => @Configuration
So, I have this in my main class (myApp.java)
package br.com.company.project.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class SomeApplication {
public static void main(String[] args) {
SpringApplication.run(SomeApplication.class, args);
}
}
And work for me! =)
Why not grab them from dependencies
in package.json
?
Of course, this will only give you the ones you actually saved, but you should be doing that anyway.
console.log(Object.keys(require('./package.json').dependencies));
?php
/* Database config */
$db_host = 'localhost';
$db_user = '~';
$db_pass = '~';
$db_database = 'banners';
/* End config */
$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_database);
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
?>
If you are using the prawn gem for Ruby on Rails to generate your PDF, you can use the following additional gem to active the print dialog:
If Symfony 4 or 5, juste use this code (Where name is the name of your field):

Try Winhttrack
...offline browser utility.
It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. HTTrack is fully configurable, and has an integrated help system.
WinHTTrack is the Windows 2000/XP/Vista/Seven release of HTTrack, and WebHTTrack the Linux/Unix/BSD release...
I don't know if you fixed it, but I did had the same issue, finally it was a dumb thing, I had:
<script src="jquery-ui/jquery-ui.min.css" rel="stylesheet">
but it should be:
<link href="jquery-ui/jquery-ui.min.css" rel="stylesheet">
Just change <scrip>
to <link>
and src
to href
This could help.
It requires the footer height to be a fixed number. Basically, you have a div inside the footer div with it's normal content, with position: absolute
, and then the image with position: relative
, a negative z-index
so it stays "below" everything, and a negative top
value of the footer's height minus the image height (in my example, 50px - 600px = -550px
). Tested in Chrome 8, FireFox 3.6 and IE 9.
Try this:
array = [
function() {},
function() {},
function() {}

function loop() {
array.forEach(item) {
