If you want to allow the user to browse for a file, you need to have an input type="file"
The closest you could get to your requirement would be to place the input type="file"
on the page and hide it. Then, trigger the click event of the input when the button is clicked:
#myFileInput {
display:none;
}
<input type="file" id="myFileInput" />
<input type="button"
onclick="document.getElementById('myFileInput').click()"
value="Select a File" />
Here's a working fiddle.
Note: I would not recommend this approach. The input type="file"
is the mechanism that users are accustomed to using for uploading a file.
This behavior is expected. flex container will stretch all its children by default. Image have no exception. (ie, parent will have align-items: stretch
property )
To keep the aspect ratio we've two solutions:
align-items: stretch
property to align-items: flex-start
or align-self: center
etc,
http://jsfiddle.net/e394Lqnt/3/or
align-self: center
or align-self: flex-start
etc.
http://jsfiddle.net/e394Lqnt/2/In google chrome element.value return the name + the path, but a fake path. Thus, for my case I used the name attribute on the file like below :
function getFileData(myFile){
var file = myFile.files[0];
var filename = file.name;
}
this is the call from the page :
<input id="ph1" name="photo" type="file" class="jq_req" onchange="getFileData(this);"/>
@Alex Martelli
's answer is great!
But it work only for one element at time (WHERE name = 'Joan'
)
If you take out the WHERE
clause, the query will return all the root rows together...
I changed a little bit for my situation, so it can show the entire tree for a table.
table definition:
CREATE TABLE [dbo].[mar_categories] (
[category] int IDENTITY(1,1) NOT NULL,
[name] varchar(50) NOT NULL,
[level] int NOT NULL,
[action] int NOT NULL,
[parent] int NULL,
CONSTRAINT [XPK_mar_categories] PRIMARY KEY([category])
)
(level
is literally the level of a category 0: root, 1: first level after root, ...)
and the query:
WITH n(category, name, level, parent, concatenador) AS
(
SELECT category, name, level, parent, '('+CONVERT(VARCHAR (MAX), category)+' - '+CONVERT(VARCHAR (MAX), level)+')' as concatenador
FROM mar_categories
WHERE parent is null
UNION ALL
SELECT m.category, m.name, m.level, m.parent, n.concatenador+' * ('+CONVERT (VARCHAR (MAX), case when ISNULL(m.parent, 0) = 0 then 0 else m.category END)+' - '+CONVERT(VARCHAR (MAX), m.level)+')' as concatenador
FROM mar_categories as m, n
WHERE n.category = m.parent
)
SELECT distinct * FROM n ORDER BY concatenador asc
(You don't need to concatenate the level
field, I did just to make more readable)
the answer for this query should be something like:
I hope it helps someone!
now, I'm wondering how to do this on MySQL... ^^
Try the following configuration:
log4j.rootLogger=TRACE, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n
log4j.appender.debugLog=org.apache.log4j.FileAppender
log4j.appender.debugLog.File=logs/debug.log
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n
log4j.appender.reportsLog=org.apache.log4j.FileAppender
log4j.appender.reportsLog.File=logs/reports.log
log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout
log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n
log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false
log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false
Then configure the loggers in the Java code accordingly:
static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");
Do you want output to go to stdout
? If not, change the first line of log4j.properties
to:
log4j.rootLogger=OFF
and get rid of the stdout
lines.
composer require vendor/package:version
for example:
composer require refinery29/test-util:0.10.2
download rpm packages and run the following command:
rpm -Uvh glibc-2.15-60.el6.x86_64.rpm \
glibc-common-2.15-60.el6.x86_64.rpm \
glibc-devel-2.15-60.el6.x86_64.rpm \
glibc-headers-2.15-60.el6.x86_64.rpm
You can use .present? which comes included with ActiveSupport.
@city = @user.city.present?
# etc ...
You could even write it like this
def show
%w(city state bio contact twitter mail).each do |attr|
instance_variable_set "@#{attr}", @user[attr].present?
end
end
It's worth noting that if you want to test if something is blank, you can use .blank?
(this is the opposite of .present?
)
Also, don't use foo == nil
. Use foo.nil?
instead.
by XML:
<EditText
android:id="@+id/search_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/search"
android:imeOptions="actionSearch"
android:inputType="text" />
By Java:
editText.clearFocus();
InputMethodManager in = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
in.hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);
Most vanilla JS Ready functions do NOT consider the scenario where the DOMContentLoaded
handler is set after the document is already loaded - Which means the function will never run. This can happen if you look for DOMContentLoaded
within an async
external script (<script async src="file.js"></script>
).
The code below checks for DOMContentLoaded
only if the document's readyState
isn't already interactive
or complete
.
var DOMReady = function(callback) {
document.readyState === "interactive" || document.readyState === "complete" ? callback() : document.addEventListener("DOMContentLoaded", callback());
};
DOMReady(function() {
//DOM ready!
});
If you want to support IE aswell:
var DOMReady = function(callback) {
if (document.readyState === "interactive" || document.readyState === "complete") {
callback();
} else if (document.addEventListener) {
document.addEventListener('DOMContentLoaded', callback());
} else if (document.attachEvent) {
document.attachEvent('onreadystatechange', function() {
if (document.readyState != 'loading') {
callback();
}
});
}
};
DOMReady(function() {
// DOM ready!
});
Syntax:
$(selector).text()
returns the text content.
$(selector).text(content)
sets the text content.
$(selector).text(function(index, curContent))
sets text content using a function.

Here is one that works for multiple duplicates and you don't need to specify any values:
List = ['A', 'B', 'A', 'C', 'E', 'B'] # duplicate two 'A's two 'B's
ix_list = []
for i in range(len(List)):
try:
dup_ix = List[(i+1):].index(List[i]) + (i + 1) # dup onwards + (i + 1)
ix_list.extend([i, dup_ix]) # if found no error, add i also
except:
pass
ix_list.sort()
print(ix_list)
[0, 1, 2, 5]
Html.CheckBox is doing something weird - if you view source on the resulting page, you'll see there's an <input type="hidden" />
being generated alongside each checkbox, which explains the "true false" values you're seeing for each form element.
Try this, which definitely works on ASP.NET MVC Beta because I've just tried it.
Put this in the view instead of using Html.CheckBox():
<% using (Html.BeginForm("ShowData", "Home")) { %>
<% foreach (var o in ViewData.Model) { %>
<input type="checkbox" name="selectedObjects" value="<%=o.Id%>">
<%= o.Name %>
<%}%>
<input type="submit" value="Submit" />
<%}%>
Your checkboxes are all called selectedObjects
, and the value
of each checkbox is the GUID of the corresponding object.
Then post to the following controller action (or something similar that does something useful instead of Response.Write())
public ActionResult ShowData(Guid[] selectedObjects) {
foreach (Guid guid in selectedObjects) {
Response.Write(guid.ToString());
}
Response.End();
return (new EmptyResult());
}
This example will just write the GUIDs of the boxes you checked; ASP.NET MVC maps the GUID values of the selected checkboxes into the Guid[] selectedObjects
parameter for you, and even parses the strings from the Request.Form collection into instantied GUID objects, which I think is rather nice.
You can easily apply colours on cell and rows.
$sheet->cell(1, function($row)
{
$row->setBackground('#CCCCCC');
});
$sheet->row(1, ['Col 1', 'Col 2', 'Col 3']);
$sheet->row(1, function($row)
{
$row->setBackground('#CCCCCC');
});
you can use the jQuery parseJSON method:
var Data = $.parseJSON(response);
Explaining multiple-inheritance with virtual bases requires a knowledge of the C++ object model. And explaining the topic clearly is best done in an article and not in a comment box.
The best, readable explanation I found that solved all my doubts on this subject was this article: http://www.phpcompiler.org/articles/virtualinheritance.html
You really won't need to read anything else on the topic (unless you are a compiler writer) after reading that...
your solution is
var i;
for(i=10; i>=0; i= i-1){
var s;
for(s=0; s<i; s = s+1){
document.write("*");
}
//printing new line
document.write("<br>");
}
void foo<TOne, TTwo>()
where TOne : BaseOne
where TTwo : BaseTwo

Use fs.writeFileSync inside the try/catch block as below.
`var fs = require('fs');
try {
const file = fs.writeFileSync(ASIN + '.json', JSON.stringify(results))
console.log("JSON saved");
return results;
} catch (error) {
console.log(err);
}`
If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}"
should do the trick.
Note: I post this answer if someone in the future face the same problem as me. For me the following line wasn't enought:
android:configChanges="orientation"
When I rotated the screen, the method `onConfigurationChanged(Configuration newConfig) did't get called.
Solution: I also had to add "screenSize" even if the problem had to do with the orientation. So in the AndroidManifest.xml - file, add this:
android:configChanges="keyboardHidden|orientation|screenSize"
Then implement the method onConfigurationChanged(Configuration newConfig)
Here is the code I was looking for :
DDL.SelectedIndex = DDL.Items.IndexOf(DDL.Items.FindByText("PassedValue"));
Or
DDL.SelectedIndex = DDL.Items.IndexOf(DDL.Items.FindByValue("PassedValue"));
Make sure of the conflict origin: if it is the result of a git merge
, see Brian Campbell's answer.
But if is the result of a git rebase
, in order to discard remote (their) changes and use local changes, you would have to do a:
git checkout --theirs -- .
See "Why is the meaning of “ours
” and “theirs
” reversed"" to see how ours
and theirs
are swapped during a rebase (because the upstream branch is checked out).
this.dtOptions = {
order: [],
columnDefs: [ {
'targets': [0], /* column index [0,1,2,3]*/
'orderable': false, /* true or false */
}],
........ rest all stuff .....
}
The above worked fine for me.
(I am using Angular version 7, angular-datatables version 6.0.0 and bootstrap version 4)

These Should work correctly On Google Chrome and Mozilla Firefox (if you are running with old version of firefox, so you have to install Firebug plugin)
On Internet Explorer 8 or higher you must do as follow:

You will first need to create a custom layout xml which will represent a single item in your list. You will add your two buttons to this layout along with any other items you want to display from your list.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/list_item_string"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:paddingLeft="8dp"
android:textSize="18sp"
android:textStyle="bold" />
<Button
android:id="@+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:text="Delete" />
<Button
android:id="@+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/delete_btn"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:text="Add" />
</RelativeLayout>
Next you will need to create a Custom ArrayAdapter Class which you will use to inflate your xml layout, as well as handle your buttons and on click events.
public class MyCustomAdapter extends BaseAdapter implements ListAdapter {
private ArrayList<String> list = new ArrayList<String>();
private Context context;
public MyCustomAdapter(ArrayList<String> list, Context context) {
this.list = list;
this.context = context;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int pos) {
return list.get(pos);
}
@Override
public long getItemId(int pos) {
return list.get(pos).getId();
//just return 0 if your list items do not have an Id variable.
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.my_custom_list_layout, null);
}
//Handle TextView and display string from your list
TextView listItemText = (TextView)view.findViewById(R.id.list_item_string);
listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners
Button deleteBtn = (Button)view.findViewById(R.id.delete_btn);
Button addBtn = (Button)view.findViewById(R.id.add_btn);
deleteBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//do something
list.remove(position); //or some other task
notifyDataSetChanged();
}
});
addBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//do something
notifyDataSetChanged();
}
});
return view;
}
}
Finally, in your activity you can instantiate your custom ArrayAdapter class and set it to your listview.
public class MyActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_activity);
//generate list
ArrayList<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
//instantiate custom adapter
MyCustomAdapter adapter = new MyCustomAdapter(list, this);
//handle listview and assign adapter
ListView lView = (ListView)findViewById(R.id.my_listview);
lView.setAdapter(adapter);
}
Hope this helps!
Another way to use .ui in your code is:
from PyQt4 import QtCore, QtGui, uic
class MyWidget(QtGui.QWidget)
...
#somewhere in constructor:
uic.loadUi('MyWidget.ui', self)
both approaches are good. Do not forget, that if you use Qt resource files (extremely useful) for icons and so on, you must compile it too:
pyrcc4.exe -o ui/images_rc.py ui/images/images.qrc
Note, when uic
compiles interface, it adds 'import images_rc' at the end of .py file, so you must compile resources into the file with this name, or rename it in generated code.
You could use a Data URI to supply the image data, for example:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<image width="20" height="20" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="/>
</svg>
The image will go through all normal svg transformations.
But this technique has disadvantages, for example the image will not be cached by the browser
Another way to do this is to use the Ruby on Rails debugger. There's a Ruby on Rails guide about debugging at http://guides.rubyonrails.org/debugging_rails_applications.html
Basically, start the server with the -u option:
./script/server -u
And then insert a breakpoint into your script where you would like to have access to the controllers, helpers, etc.
class EventsController < ApplicationController
def index
debugger
end
end
And when you make a request and hit that part in the code, the server console will return a prompt where you can then make requests, view objects, etc. from a command prompt. When finished, just type 'cont' to continue execution. There are also options for extended debugging, but this should at least get you started.
It can be done by simply declaring one function which will handle all your swipe UISwipeGestureRecognizer directions. Here is my code:
let swipeGestureRight = UISwipeGestureRecognizer(target: self, action:#selector(ViewController.respondToSwipeGesture(_:)) )
swipeGestureRight.direction = UISwipeGestureRecognizerDirection.right
self.view .addGestureRecognizer(swipeGestureRight)
let swipeGestureLeft = UISwipeGestureRecognizer(target: self, action: #selector(ViewController.respondToSwipeGesture(_:)))
swipeGestureLeft.direction = UISwipeGestureRecognizerDirection.left
self.view.addGestureRecognizer(swipeGestureLeft)
let swipeGestureUp = UISwipeGestureRecognizer(target: self, action: #selector(ViewController.respondToSwipeGesture(_:)))
swipeGestureUp.direction = UISwipeGestureRecognizerDirection.up
self.view.addGestureRecognizer(swipeGestureUp)
let swipeGestureDown = UISwipeGestureRecognizer(target: self, action: #selector(ViewController.respondToSwipeGesture(_:)))
swipeGestureDown.direction = UISwipeGestureRecognizerDirection.down
self.view.addGestureRecognizer(swipeGestureDown)
Here is the function which will hande the swipedirection functionality:
func respondToSwipeGesture(_ sender: UIGestureRecognizer) {
if let swipeGesture = sender as? UISwipeGestureRecognizer {
switch swipeGesture.direction {
case UISwipeGestureRecognizerDirection.right:
print("right swipe")
case UISwipeGestureRecognizerDirection.left:
print("leftSwipe")
case UISwipeGestureRecognizerDirection.up:
print("upSwipe")
case UISwipeGestureRecognizerDirection.down:
print("downSwipe")
default:
break
}
}
}
The VOLUME
command will mount a directory inside your container and store any files created or edited inside that directory on your hosts disk outside the container file structure, bypassing the union file system.
The idea is that your volumes can be shared between your docker containers and they will stay around as long as there's a container (running or stopped) that references them.
You can have other containers mount existing volumes (effectively sharing them between containers) by using the --volumes-from
command when you run a container.
The fundamental difference between VOLUME
and -v
is this: -v
will mount existing files from your operating system inside your docker container and VOLUME
will create a new, empty volume on your host and mount it inside your container.
Example:
VOLUME /var/lib/mysql
.some-volume
And then,
docker run --volumes-from some-volume docker-image-name:tag
some-volume
mounted in /var/lib/mysql
Note: Using --volumes-from
will mount the volume over whatever exists in the location of the volume. I.e., if you had stuff in /var/lib/mysql
, it will be replaced with the contents of the volume.
I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.
I had <meta http-equiv="x-ua-compatible" content="ie=edge">
on the page.
In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.
There is a great implementation of NavigationDrawer
that follows the Google Material Design Guidelines (and compatible down to API 10) - The MaterialDrawer library (link to GitHub). As of time of writing, May 2017, it's actively supported.
It's available in Maven Central repo. Gradle dependency setup:
compile 'com.mikepenz:materialdrawer:5.9.1'
Maven dependency setup:
<dependency>
<groupId>com.mikepenz</groupId>
<artifactId>materialdrawer</artifactId>
<version>5.9.1</version>
</dependency>
Do you have ROWS of data (horizontal) as you stated or COLUMNS (vertical)?
If it's the latter you can use "Text to columns" functionality to convert a whole column "in situ" - to do that:
Select column > Data > Text to columns > Next > Next > Choose "Date" under "column data format" and "YMD" from dropdown > Finish
....otherwise you can convert with a formula by using
=TEXT(A1,"0000-00-00")+0
and format in required date format
If you use Spring you can:
1) create a log4j configuration file, e.g. "/WEB-INF/classes/log4j-myapp.properties" DO NOT name it "log4j.properties"
Example:
log4j.rootLogger=ERROR, stdout, rollingFile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n
log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=${myWebapp-instance-root}/WEB-INF/logs/application.log
log4j.appender.rollingFile.MaxFileSize=512KB
log4j.appender.rollingFile.MaxBackupIndex=10
log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.rollingFile.Encoding=UTF-8
We'll define "myWebapp-instance-root" later on point (3)
2) Specify config location in web.xml:
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j-myapp.properties</param-value>
</context-param>
3) Specify a unique variable name for your webapp's root, e.g. "myWebapp-instance-root"
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>myWebapp-instance-root</param-value>
</context-param>
4) Add a Log4jConfigListener:
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
If you choose a different name, remember to change it in log4j-myapp.properties, too.
See my article (Italian only... but it should be understandable): http://www.megadix.it/content/configurare-path-relativi-log4j-utilizzando-spring
UPDATE (2009/08/01) I've translated my article to English: http://www.megadix.it/node/136
Here's a revised version of your code which still works plus it illustrates how to raise a ValueError
the way you want. By-the-way, I think find_last()
, find_last_index()
, or something simlar would be a more descriptive name for this function. Adding to the possible confusion is the fact that Python already has a container object method named __contains__()
that does something a little different, membership-testing-wise.
def contains(char_string, char):
largest_index = -1
for i, ch in enumerate(char_string):
if ch == char:
largest_index = i
if largest_index > -1: # any found?
return largest_index # return index of last one
else:
raise ValueError('could not find {!r} in {!r}'.format(char, char_string))
print(contains('mississippi', 's')) # -> 6
print(contains('bababa', 'k')) # ->
Traceback (most recent call last):
File "how-to-raise-a-valueerror.py", line 15, in <module>
print(contains('bababa', 'k'))
File "how-to-raise-a-valueerror.py", line 12, in contains
raise ValueError('could not find {} in {}'.format(char, char_string))
ValueError: could not find 'k' in 'bababa'
Update — A substantially simpler way
Wow! Here's a much more concise version—essentially a one-liner—that is also likely faster because it reverses (via [::-1]
) the string before doing a forward search through it for the first matching character and it does so using the fast built-in string index()
method. With respect to your actual question, a nice little bonus convenience that comes with using index()
is that it already raises a ValueError
when the character substring isn't found, so nothing additional is required to make that happen.
Here it is along with a quick unit test:
def contains(char_string, char):
# Ending - 1 adjusts returned index to account for searching in reverse.
return len(char_string) - char_string[::-1].index(char) - 1
print(contains('mississippi', 's')) # -> 6
print(contains('bababa', 'k')) # ->
Traceback (most recent call last):
File "better-way-to-raise-a-valueerror.py", line 9, in <module>
print(contains('bababa', 'k'))
File "better-way-to-raise-a-valueerror", line 6, in contains
return len(char_string) - char_string[::-1].index(char) - 1
ValueError: substring not found

Simple way is that you have "Collections" in Java. You just need to call it and use "reverse()" method of it.
Example usage:
ArrayList<Integer> yourArrayList = new ArrayList<>();
yourArrayList.add(1);
yourArrayList.add(2);
yourArrayList.add(3);
//yourArrayList is: 1,2,3
Collections.reverse(yourArrayList);
// Now, yourArrayList is: 3,2,1

You can directly give the source property of the current object in the img src attribute. Please see my code below:
<div *ngFor="let brochure of brochureList">
<img class="brochure-poster" [src]="brochure.imageUrl" />
</div>
NOTE: You can as well use string interpolation but that is not a legit way to do it. Property binding was created for this very purpose hence better use this.
NOT RECOMMENDED :
<img class="brochure-poster" src="{{brochure.imageUrl}}"/>
Its because that defeats the purpose of property binding. It is more meaningful to use that for setting the properties. {{}} is a normal string interpolation expression, that does not reveal to anyone reading the code that it makes special meaning. Using [] makes it easily to spot the properties that are set dynamically.
Here is my brochureList contains the following json received from service(you can assign it to any variable):

},
{
"productId":2,

sudo vim /Applications/MAMP/Library/my.cnf
And Add like this
[mysqld]

The approach I suggest is a bit verbose but I found it to scale pretty well into complex apps. When you want to show a modal, fire an action describing which modal you'd like to see:
this.props.dispatch({
type: 'SHOW_MODAL',
modalType: 'DELETE_POST',
modalProps: {
postId: 42
}
})
(Strings can be constants of course; I’m using inline strings for simplicity.)
Then make sure you have a reducer that just accepts these values:
const initialState = {
modalType: null,
modalProps: {}
}
function modal(state = initialState, action) {
switch (action.type) {
case 'SHOW_MODAL':
return {
modalType: action.modalType,
modalProps: action.modalProps
}
case 'HIDE_MODAL':
return initialState
default:
return state
}
}
/* .... */
const rootReducer = combineReducers({
modal,
/* other reducers */
})
Great! Now, when you dispatch an action, state.modal
will update to include the information about the currently visible modal window.
At the root of your component hierarchy, add a <ModalRoot>
component that is connected to the Redux store. It will listen to state.modal
and display an appropriate modal component, forwarding the props from the state.modal.modalProps
.
// These are regular React components we will write soon
import DeletePostModal from './DeletePostModal'
import ConfirmLogoutModal from './ConfirmLogoutModal'
const MODAL_COMPONENTS = {
'DELETE_POST': DeletePostModal,
'CONFIRM_LOGOUT': ConfirmLogoutModal,
/* other modals */
}
const ModalRoot = ({ modalType, modalProps }) => {
if (!modalType) {
return <span /> // after React v15 you can return null here
}
const SpecificModal = MODAL_COMPONENTS[modalType]
return <SpecificModal {...modalProps} />
}
export default connect(
state => state.modal
)(ModalRoot)
What have we done here? ModalRoot
reads the current modalType
and modalProps
from state.modal
to which it is connected, and renders a corresponding component such as DeletePostModal
or ConfirmLogoutModal
. Every modal is a component!
There are no general rules here. They are just React components that can dispatch actions, read something from the store state, and just happen to be modals.
For example, DeletePostModal
might look like:
import { deletePost, hideModal } from '../actions'
const DeletePostModal = ({ post, dispatch }) => (
<div>
<p>Delete post {post.name}?</p>
<button onClick={() => {
dispatch(deletePost(post.id)).then(() => {
dispatch(hideModal())
})
}}>
Yes
</button>
<button onClick={() => dispatch(hideModal())}>
Nope
</button>
</div>
)
export default connect(
(state, ownProps) => ({
post: state.postsById[ownProps.postId]
})
)(DeletePostModal)
The DeletePostModal
is connected to the store so it can display the post title and works like any connected component: it can dispatch actions, including hideModal
when it is necessary to hide itself.
It would be awkward to copy-paste the same layout logic for every “specific” modal. But you have components, right? So you can extract a presentational <Modal>
component that doesn’t know what particular modals do, but handles how they look.
Then, specific modals such as DeletePostModal
can use it for rendering:
import { deletePost, hideModal } from '../actions'
import Modal from './Modal'
const DeletePostModal = ({ post, dispatch }) => (
<Modal
dangerText={`Delete post ${post.name}?`}
onDangerClick={() =>
dispatch(deletePost(post.id)).then(() => {
dispatch(hideModal())
})
})
/>
)
export default connect(
(state, ownProps) => ({
post: state.postsById[ownProps.postId]
})
)(DeletePostModal)
It is up to you to come up with a set of props that <Modal>
can accept in your application but I would imagine that you might have several kinds of modals (e.g. info modal, confirmation modal, etc), and several styles for them.
The last important part about modals is that generally we want to hide them when the user clicks outside or presses Escape.
Instead of giving you advice on implementing this, I suggest that you just don’t implement it yourself. It is hard to get right considering accessibility.
Instead, I would suggest you to use an accessible off-the-shelf modal component such as react-modal
. It is completely customizable, you can put anything you want inside of it, but it handles accessibility correctly so that blind people can still use your modal.
You can even wrap react-modal
in your own <Modal>
that accepts props specific to your applications and generates child buttons or other content. It’s all just components!
There is more than one way to do it.
Some people don’t like the verbosity of this approach and prefer to have a <Modal>
component that they can render right inside their components with a technique called “portals”. Portals let you render a component inside yours while actually it will render at a predetermined place in the DOM, which is very convenient for modals.
In fact react-modal
I linked to earlier already does that internally so technically you don’t even need to render it from the top. I still find it nice to decouple the modal I want to show from the component showing it, but you can also use react-modal
directly from your components, and skip most of what I wrote above.
I encourage you to consider both approaches, experiment with them, and pick what you find works best for your app and for your team.
Same can be done with async await and arrow function
server.get('/usersList', async (req, res) => {
const users = await User.find({});
const userMap = {};
users.forEach((user) => {
userMap[user._id] = user;
});
res.send(userMap);
});
You have to loop through the array, no other way to check all elements. Just one correction for the code - if all elements are negative, maxValue will be 0 at the end. You should initialize it with the minimum possible value for integer.
And if you are going to search the array many times it's a good idea to sort it first, than searching is faster (binary search) and minimum and maximum elements are just the first and the last.
see here
The consumable media types of the mapped request, narrowing the primary mapping.
the producer is used to narrow the primary mapping, you send request should specify the exact header to match it.
.list-wrap {
width: 355px;
height: 100%;
position: relative;
.list {
position: absolute;
top: 0;
bottom: 0;
overflow-y: auto;
width: 100%;
}
}
map(float, mylist)
should do it.
(In Python 3, map ceases to return a list object, so if you want a new list and not just something to iterate over, you either need list(map(float, mylist)
- or use SilentGhost's answer which arguably is more pythonic.)
It's not necessary to call repaint unless you need to render something specific onto a component. "Something specific" meaning anything that isn't provided internally by the windowing toolkit you're using.
From another point of view: Consider that you want to make some changes on a single String. for example you want to make the letters Uppercase and so on. you make another class named "Tools" for these actions. there is no meaning of making instance of "Tools" class because there is not any kind of entity available inside that class (compare to "Person" or "Teacher" class). So we use static keyword in order to use "Tools" class without making any instance of that, and when you press dot after class name ("Tools") you can have access to the methods you want.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(Tools.ToUpperCase("Behnoud Sherafati"));
Console.ReadKey();
}
}
public static class Tools
{
public static string ToUpperCase(string str)
{
return str.ToUpper();
}
}
}
First we'll consider loops where the number of iterations of the inner loop is independent of the value of the outer loop's index. For example:
for (i = 0; i < N; i++) {
for (j = 0; j < M; j++) {
sequence of statements
}
}
The outer loop executes N times. Every time the outer loop executes, the inner loop executes M times. As a result, the statements in the inner loop execute a total of N * M times. Thus, the total complexity for the two loops is O(N2).
A new version for the scenario where the callback will be called by some other function, not your own code, and you want to add additional parameters.
For example, let's pretend that you have a lot of nested calls with success and error callbacks. I will use angular promises for this example but any javascript code with callbacks would be the same for the purpose.
someObject.doSomething(param1, function(result1) {
console.log("Got result from doSomething: " + result1);
result.doSomethingElse(param2, function(result2) {
console.log("Got result from doSomethingElse: " + result2);
}, function(error2) {
console.log("Got error from doSomethingElse: " + error2);
});
}, function(error1) {
console.log("Got error from doSomething: " + error1);
});
Now you may want to unclutter your code by defining a function to log errors, keeping the origin of the error for debugging purposes. This is how you would proceed to refactor your code:
someObject.doSomething(param1, function (result1) {
console.log("Got result from doSomething: " + result1);
result.doSomethingElse(param2, function (result2) {
console.log("Got result from doSomethingElse: " + result2);
}, handleError.bind(null, "doSomethingElse"));
}, handleError.bind(null, "doSomething"));
/*
* Log errors, capturing the error of a callback and prepending an id
*/
var handleError = function (id, error) {
var id = id || "";
console.log("Got error from " + id + ": " + error);
};
The calling function will still add the error parameter after your callback function parameters.
You just need to turn SSL off to send your request.
Proxy and others come with various errors.
Make sure that the directory exists, you have permission to access it and add the file to the path to write the log:
File file = new File("D:/Data/" + item.getFileName());
In this case, UIButton

I wanted to reuse "UIBarButtonItem

doesn't offer method sendActionsForControlEvents:
But luckily, UIBarButtonItem
has properties for target & action.
if(notHappy){
SEL exit = self.navigationItem.rightBarButtonItem.action;
id world = self.navigationItem.rightBarButtonItem.target;
[world performSelector:exit];
}
Here, rightBarButtonItem
is of type UIBarButtonItem
.
You probably don't included the path to mysql headers, which can be found at /usr/include/mysql, on several unix systems I think. See this post, it may be helpfull.
By the way, related with the question of that guy above, about syntastic configuration. One can add the following to your ~/.vimrc:
let b:syntastic_c_cflags = '-I/usr/include/mysql'
and you can always check the wiki page of the developers on github. Enjoy!
To count all occurrences, use -o
. Try this:
echo afoobarfoobar | grep -o foo | wc -l
And man grep
of course (:
Some suggest to use just grep -co foo
instead of grep -o foo | wc -l
.
Don't.
This shortcut won't work in all cases. Man page says:
-c print a count of matching lines
Difference in these approaches is illustrated below:
1.
$ echo afoobarfoobar | grep -oc foo
1
As soon as the match is found in the line (a{foo}barfoobar
) the searching stops. Only one line was checked and it matched, so the output is 1
. Actually -o
is ignored here and you could just use grep -c
instead.
2.
$ echo afoobarfoobar | grep -o foo
foo
foo
$ echo afoobarfoobar | grep -o foo | wc -l
2
Two matches are found in the line (a{foo}bar{foo}bar
) because we explicitly asked to find every occurrence (-o
). Every occurence is printed on a separate line, and wc -l
just counts the number of lines in the output.
nop... just open the four dateis: content.xml; server.xml; tomcat-users.xml and web.xml in the tap servers. There are some text. Change the number of port 8080 to 8081
For me it was the "Start In" - I accidentally left in the '.py' at the end of the name of my program. And I forgot to capitalize the name of the folder it was in ('Apps').
decimal
.columnName decimal(precision, scale)
. Precision says the total number of digits that can be held in the number, scale says how many of those are after the decimal place, so decimal(3,2)
is a number which can be represented as #.##
; decimal(5,3)
would be ##.###
. decimal
and numeric
are essentially the same thing. However decimal
is ANSI compliant, so always use that unless told otherwise (e.g. by your company's coding standards).Example Scenarios
decimal(5,4)
.decimal(3,2)
.Example:
if object_id('Demo') is null
create table Demo
(
Id bigint not null identity(1,1) constraint pk_Demo primary key
, Name nvarchar(256) not null constraint uk_Demo unique
, SomePercentValue decimal(3,2) constraint chk_Demo_SomePercentValue check (SomePercentValue between 0 and 1)
, SomePrecisionPercentValue decimal(5,2) constraint chk_Demo_SomePrecisionPercentValue check (SomePrecisionPercentValue between 0 and 1)
)

Quite straight. This can be a good starting point
int makeDir(char *fullpath, mode_t permissions){
int i=0;
char *arrDirs[20];
char aggrpaz[255];
arrDirs[i] = strtok(fullpath,"/");
strcpy(aggrpaz, "/");
while(arrDirs[i]!=NULL)
{
arrDirs[++i] = strtok(NULL,"/");
strcat(aggrpaz, arrDirs[i-1]);
mkdir(aggrpaz,permissions);
strcat(aggrpaz, "/");
}
i=0;
return 0;
}
You parse this function a full path plus the permissions you want, i.e S_IRUSR, for a full list of modes go here https://techoverflow.net/2013/04/05/how-to-use-mkdir-from-sysstat-h/
The fullpath string will be split by the "/" character and individual dirs will be appended to the aggrpaz string one at a time. Each loop iteration calls the mkdir function, passing it the aggregate path so far plus the permissions. This example can be improved, I am not checking the mkdir function output and this function only works with absolute paths.
The following interface became deprecated in pip 10:

from pip.download import PipSession
So I switched it just to simple text parsing:

s for s in [
line.split('#', 1)[0].strip(' \t\n') for line in f
] if s != ''
]
If your Gridview
used with AutoGenerateDeleteButton="true"
, you may convert it to LinkButton
:
Click GridView Tasks and then Edit Columns.
Select Delete in Selected fields, and click on Convert this field into a TemplateField. Then click OK:
Now your LinkButton
will be generated. You can add OnClientClick
event to the LinkButton
like this:
OnClientClick="return confirm('Are you sure you want to delete?'); "
"UPDATE TableName SET TableField = TableField + 1 WHERE SomeFilterField = @ParameterID"
Action method needs to return FileResult with either a stream, byte[], or virtual path of the file. You will also need to know the content-type of the file being downloaded. Here is a sample (quick/dirty) utility method. Sample video link How to download files using asp.net core

Here's a solution which will work even when JavaScript is disabled:
<form action="login.html">
<button type="submit">Login</button>
</form>
The trick is to surround the button with its own <form>
tag.
I personally prefer the <button>
tag, but you can do it with <input>
as well:
<form action="login.html">
<input type="submit" value="Login"/>
</form>
I created a more developed jQuery plugin that allows you to lock or unlock the map with a nice button.
This plugin disables the Google Maps iframe with a transparent overlay div and adds a button for unlockit. You must press for 650 milliseconds to unlock it.

In plain English, the syntax explained:

do_something_if_condition_is_met;
}
else{
do_something_else_if_condition_is_not_met;
}
Can be written as:
condition ? do_something_if_condition_is_met : do_something_else_if_condition_is_not_met;
To create a new branch (locally):
With the commit hash (or part of it)
git checkout -b new_branch 6e559cb
or to go back 4 commits from HEAD
git checkout -b new_branch HEAD~4
Once your new branch is created (locally), you might want to replicate this change on a remote of the same name: How can I push my changes to a remote branch
For discarding the last three commits, see Lunaryorn's answer below.
For moving your current branch HEAD to the specified commit without creating a new branch, see Arpiagar's answer below.

It is perfectly valid (at least by HTML 4.01 and XHTML 1.0 standards) to nest either a <span>
inside an <a>
or an <a>
inside a <span>
.
Just to prove it to yourself, you can always check it out an the W3C MarkUp Validation Service
I tried validating:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Title</title>
</head>
<body>
<p>
<a href="http://www.google.com/"><span>Google</span></a>
</p>
</body>
</html>
And also the same as above, but with the <a>
inside the <span>
i.e.
<span><a href="http://www.google.com">Google</a></span>
with both HTML 4.01 and XHTML 1.0 doctypes, and both passed validation successfully!
Only thing to be aware of is to ensure that you close the tags in the correct order. So if you start with a <span>
then an <a>
, make sure you close the <a>
tag first before closing the <span>
and vice-versa.
No. But there are other options out there like Overlib, and jQuery that allow you this freedom.
Personally, I would suggest jQuery as the route to take. It's typically very unobtrusive, and requires no additional setup in the markup of your site (with the exception of adding the jquery script tag in your <head>).
In bootstrap 3 the format is

A way to do it without losing the changes you wanted:
git reset cc4b63b
git stash
git push -f origin alpha-0.3.0
git stash pop
Then you can choose the files you meant to push

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"
android:scrollbars="vertical"/>

I figured it out. Basically it's an async issue. You can't just submit and expect to render the subsequent page immediately. You have to wait until the onLoad event for the next page is triggered. My code is below:
var page = new WebPage(), testindex = 0, loadInProgress = false;
page.onConsoleMessage = function(msg) {
console.log(msg);
};
page.onLoadStarted = function() {
loadInProgress = true;
console.log("load started");
};
page.onLoadFinished = function() {
loadInProgress = false;
console.log("load finished");
};
var steps = [
function() {
//Load Login Page
page.open("https://website.com/theformpage/");
},
function() {
//Enter Credentials
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].elements["email"].value="mylogin";
arr[i].elements["password"].value="mypassword";
return;
}
}
});
},
function() {
//Login
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].submit();
return;
}
}
});
},
function() {
// Output content of page to stdout after form has been submitted
page.evaluate(function() {
console.log(document.querySelectorAll('html')[0].outerHTML);
});
}
];
interval = setInterval(function() {
if (!loadInProgress && typeof steps[testindex] == "function") {
console.log("step " + (testindex + 1));
steps[testindex]();
testindex++;
}
if (typeof steps[testindex] != "function") {
console.log("test complete!");
phantom.exit();
}
}, 50);
PowerShell solution
Using Posh-SSH:
New-SSHSession -ComputerName 0.0.0.0 -Credential $cred | Out-Null
Invoke-SSHCommand -SessionId 1 -Command "nohup sleep 5 >> abs.log &" | Out-Null
The functions need to be defined before being used. There is no mechanism is sh to pre-declare functions, but a common technique is to do something like:
main() { case "$choice" in true) process_install;; false) process_exit;; esac } process_install() { commands... commands... } process_exit() { commands... commands... } main()
gcc has a so-called "case range" extension:
http://gcc.gnu.org/onlinedocs/gcc-4.2.4/gcc/Case-Ranges.html#Case-Ranges
I used to use this when I was only using gcc. Not much to say about it really -- it does sort of what you want, though only for ranges of values.
The biggest problem with this is that only gcc supports it; this may or may not be a problem for you.
(I suspect that for your example an if
statement would be a more natural fit.)
You can use regular expression operator (~), separated by (|) as described in Pattern Matching
select column_a from table where column_a ~* 'aaa|bbb|ccc'
That is a "set subtraction" operation. Use the set data structure for that.
In Python 2.7:
x = {1,2,3,4,5,6,7,8,9,0}
y = {1,3,5,7,9}
print x - y
Output:
>>> print x - y
set([0, 8, 2, 4, 6])

I think the confusion in your question is because you have React components which you are being passed the id "Progress1", "Progress2" etc. I believe this is not setting the html attribute 'id', but the React component property. e.g.
class ProgressBar extends React.Component {
constructor(props) {
super(props)
this.state = {
id: this.props.id <--- ID set from <ProgressBar id="Progress1"/>
}
}
}
As mentioned in some of the answers above you absolutely can use document.querySelector
inside of your React app, but you have to be clear that it is selecting the html output of your components' render methods. So assuming your render output looks like this:
render () {
const id = this.state.id
return (<div id={"progress-bar-" + id}></div>)
}
Then you can elsewhere do a normal javascript querySelector call like this:
let element = document.querySelector('#progress-bar-Progress1')
This works in Hibernate 4(Tested).
String hql="select count(*) from Book";
Query query= getCurrentSession().createQuery(hql);
Long count=(Long) query.uniqueResult();
return count;
Where getCurrentSession() is:
@Autowired
private SessionFactory sessionFactory;
private Session getCurrentSession(){
return sessionFactory.getCurrentSession();
}

This is the ASCII format.
Please consider that:
Some data (like URLs) can be sent over the Internet using the ASCII character-set. Since data often contain characters outside the ASCII set, so it has to be converted into a valid ASCII format.
To find it yourself, you can visit https://en.wikipedia.org/wiki/ASCII, there you can find big tables of characters. The one you are looking is in Control Characters
table.
Digging to table you can find

In the html file you can use Dec and Hex representation of charters
The Dec
is represented with

For everyone having the same issue, make sure you actually wrote "120px" instead of only "120". This was my mistake and it drove me crazy.
almost a decade passed but the issue still valid with Asp.Net Core 2.2 as well.
I managed it by adding data-val-number

According to Google's Machine Learning Glossary, an epoch is defined as
"A full training pass over the entire dataset such that each example has been seen once. Thus, an epoch represents N/batch_size
training iterations, where N is the total number of examples."
If you are training model for 10 epochs with batch size 6, given total 12 samples that means:
the model will be able to see whole dataset in 2 iterations ( 12 / 6 = 2) i.e. single epoch.
overall, the model will have 2 X 10 = 20 iterations (iterations-per-epoch X no-of-epochs)
re-evaluation of loss and model parameters will be performed after each iteration!

Install lxml from http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml for your python version. It's a precompiled WHL with required modules/dependencies.
The site lists several packages, when e.g. using Win32 Python 3.9, use lxml-4.5.2-cp39-cp39-win32.whl
.
Download the file, and then install with:
pip install C:\path\to\downloaded\file\lxml-4.5.2-cp39-cp39-win32.whl

you should use mysql
command. It's a command line client for mysql RDBMS, and comes with most mysql installations: http://dev.mysql.com/doc/refman/5.1/en/mysql.html
To stop or start mysql database (you rarely should need doing that 'by hand'), use proper init script with stop
or start
parameter, usually /etc/init.d/mysql stop
. This, however depends on your linux distribution. Some new distributions encourage service mysql start
style.
You're logging in by using mysql
sql shell.
The error comes probably because double '-p' parameter. You can provide -ppassword
or just -p
and you'll be asked for password interactively. Also note, that some instalations might use mysql (not root) user as an administrative user. Check your sqlyog configuration to obtain working connection parameters.

Q: Can vue-router open link in new tab progammaticaly
A: No. use a normal link.
A variable that shows caps lock state:
let isCapsLockOn = false;
document.addEventListener( 'keydown', function( event ) {
var caps = event.getModifierState && event.getModifierState( 'CapsLock' );
if(isCapsLockOn !== caps) isCapsLockOn = caps;
});
document.addEventListener( 'keyup', function( event ) {
var caps = event.getModifierState && event.getModifierState( 'CapsLock' );
if(isCapsLockOn !== caps) isCapsLockOn = caps;
});
works on all browsers => canIUse
C++20 introduced a guarantee that time_since_epoch
is relative to the UNIX epoch, and cppreference.com gives an example that I've distilled to the relevant code, and changed to units of seconds rather than hours:
#include <iostream>
#include <chrono>
int main()
{
const auto p1 = std::chrono::system_clock::now();
std::cout << "seconds since epoch: "
<< std::chrono::duration_cast<std::chrono::seconds>(
p1.time_since_epoch()).count() << '\n';
}
Using C++17 or earlier, time()
is the simplest function - seconds since Epoch, which for Linux and UNIX at least would be the UNIX epoch. Linux manpage here.
The cppreference page linked above gives this example:
#include <ctime>
#include <iostream>
int main()
{
std::time_t result = std::time(nullptr);
std::cout << std::asctime(std::localtime(&result))
<< result << " seconds since the Epoch\n";
}

Here is how to install it:

I think you should use python wheels for distribution instead of egg now.
Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.
let's say you want a pointer to point at the address 0x28ff4402, the usual way is
uint32_t *ptr;
ptr = (uint32_t*) 0x28ff4402 //type-casting the address value to uint32_t pointer
*ptr |= (1<<13) | (1<<10); //access the address how ever you want
So the short way is to use a MACRO,
#define ptr *(uint32_t *) (0x28ff4402)
The only viable solution in my opinion is to use
ID INT IDENTITY(1,1)
column to get SQL Server to handle the automatic increment of your numeric valueSo try this:
CREATE TABLE dbo.tblUsers
(ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
UserID AS 'UID' + RIGHT('00000000' + CAST(ID AS VARCHAR(8)), 8) PERSISTED,
.... your other columns here....
)
Now, every time you insert a row into tblUsers
without specifying values for ID
or UserID
:
INSERT INTO dbo.tblUsersCol1, Col2, ..., ColN)
VALUES (Val1, Val2, ....., ValN)
then SQL Server will automatically and safely increase your ID
value, and UserID
will contain values like UID00000001
, UID00000002
,...... and so on - automatically, safely, reliably, no duplicates.
Update: the column UserID
is computed - but it still OF COURSE has a data type, as a quick peek into the Object Explorer reveals:
I believe your problem is this: in your while loop, n is divided by 2, but never cast as an integer again, so it becomes a float at some point. It is then added onto y, which is then a float too, and that gives you the warning.
Actually I am preferring to use NEW_BROKER
,it is working fine on all cases:
ALTER DATABASE [dbname] SET NEW_BROKER WITH ROLLBACK IMMEDIATE;
If above not worked properly. Then, make sure that u have installed the visual studio first before installation of IIS,
For better solution uninstall visual studio and then again install first IIS properly then visual studio
You can just use the View.setId(integer)
for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views
you add programmatically.
According to
View
documentationThe identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.
So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

Probabily you are using XMAPP as service, to restart XMAPP properly, you have to open XMAPP control panel un-check both "Svc" mdodules against Apache and MySQL. Then click on exit, now restart XMAPP and you are done.
Thanks to @Birchlabs' comment, now it is tons easier with this special Mac-only DNS name available:
docker run -e DB_PORT=5432 -e DB_HOST=docker.for.mac.host.internal
From 17.12.0-cd-mac46, docker.for.mac.host.internal
should be used instead of docker.for.mac.localhost
. See release note for details.
@helmbert's answer well explains the issue. But Docker for Mac does not expose the bridge network, so I had to do this trick to workaround the limitation:
$ sudo ifconfig lo0 alias 10.200.10.1/24
Open /usr/local/var/postgres/pg_hba.conf
and add this line:
host all all 10.200.10.1/24 trust
Open /usr/local/var/postgres/postgresql.conf
and edit change listen_addresses
:
listen_addresses = '*'
Reload service and launch your container:
$ PGDATA=/usr/local/var/postgres pg_ctl reload
$ docker run -e DB_PORT=5432 -e DB_HOST=10.200.10.1 my_app
What this workaround does is basically same with @helmbert's answer, but uses an IP address that is attached to lo0
instead of docker0
network interface.

As of Swift 3 / 4 / 5, this is done as follows.
To add a new element to the end of an Array.
anArray.append("This String")
To append a different Array to the end of your Array.
anArray += ["Moar", "Strings"]
anArray.append(contentsOf: ["Moar", "Strings"])
To insert a new element into your Array.
anArray.insert("This String", at: 0)
To insert the contents of a different Array into your Array.
anArray.insert(contentsOf: ["Moar", "Strings"], at: 0)
More information can be found in the "Collection Types" chapter of "The Swift Programming Language", starting on page 110.
If I'm correct in thinking that you want to find the minimum value of a function for all possible pairs of 2 elements from a list...
l = [1,2,3,4,5]
def f(i,j):
return i+j
# Prints min value of f(i,j) along with i and j
print min( (f(i,j),i,j) for i in l for j in l)
Regarding Fred the Fantastic's answer:
Not every JPEG marker between C0
-CF
are SOF
markers; I excluded DHT (C4
), DNL (C8
) and DAC (CC
). Note that I haven't looked into whether it is even possible to parse any frames other than C0
and C2
in this manner. However, the other ones seem to be fairly rare (I personally haven't encountered any other than C0
and C2
).
Either way, this solves the problem mentioned in comments by Malandy with Bangles.jpg
(DHT erroneously parsed as SOF).
The other problem mentioned with 1431588037-WgsI3vK.jpg
is due to imghdr
only being able detect the APP0 (EXIF) and APP1 (JFIF) headers.
This can be fixed by adding a more lax test to imghdr (e.g. simply FFD8
or maybe FFD8FF
?) or something much more complex (possibly even data validation). With a more complex approach I've only found issues with: APP14 (FFEE
) (Adobe); the first marker being DQT (FFDB
); and APP2 and issues with embedded ICC_PROFILEs.
Revised code below, also altered the call to imghdr.what()
slightly:
import struct
import imghdr
def test_jpeg(h, f):
# SOI APP2 + ICC_PROFILE
if h[0:4] == '\xff\xd8\xff\xe2' and h[6:17] == b'ICC_PROFILE':
print "A"
return 'jpeg'
# SOI APP14 + Adobe
if h[0:4] == '\xff\xd8\xff\xee' and h[6:11] == b'Adobe':
return 'jpeg'
# SOI DQT
if h[0:4] == '\xff\xd8\xff\xdb':
return 'jpeg'
imghdr.tests.append(test_jpeg)
def get_image_size(fname):
'''Determine the image type of fhandle and return its size.
from draco'''
with open(fname, 'rb') as fhandle:
head = fhandle.read(24)
if len(head) != 24:
return
what = imghdr.what(None, head)
if what == 'png':
check = struct.unpack('>i', head[4:8])[0]
if check != 0x0d0a1a0a:
return
width, height = struct.unpack('>ii', head[16:24])
elif what == 'gif':
width, height = struct.unpack('<HH', head[6:10])
elif what == 'jpeg':
try:
fhandle.seek(0) # Read 0xff next
size = 2
ftype = 0
while not 0xc0 <= ftype <= 0xcf or ftype in (0xc4, 0xc8, 0xcc):
fhandle.seek(size, 1)
byte = fhandle.read(1)
while ord(byte) == 0xff:
byte = fhandle.read(1)
ftype = ord(byte)
size = struct.unpack('>H', fhandle.read(2))[0] - 2
# We are at a SOFn block
fhandle.seek(1, 1) # Skip `precision' byte.
height, width = struct.unpack('>HH', fhandle.read(4))
except Exception: #IGNORE:W0703

I think may be more automatic, grunt task usemin take care to do all this jobs for you, only need some configuration:
Save a copy of your spreadsheet first (just in case).
Insert two new columns to the left of the numbered column.
Put a k in the first row of the first (new) column.
Copy it (the k).
Go to the original first column (now the third column) and leave your cursor on the first row that has data.
Hit ctrl and down arrow (at the same time) to jump to the bottom of the populated data range for your original first column.
Left arrow twice to get to the new first column, the one with a k at the very top.
Hit Ctrl-shift-up arrow to go to the first cell with data populated (the original k you put in), highlighting all the cells in-between your starting and ending point.
Use paste (ctrl-v, right-click or whatever your preferred method), and it'll fill all those cells with a k.
Then use the "Concatenate" formula in the second column. Its two arguments will be the column of Ks (column A, first column) and the column with the numbers in it.
This will get you a column with the results of the K column and your numbers.
Hope this helps! The ctrl-shift-arrow and ctrl-arrow shortcuts are amazing for working with large datasets in Excel.

There is no proper way to add multiple jar libraries from the folder using Maven. If there are only few dependencies, it is probably easier to configure maven-install-plugin

I needed to do replicate these heights properly in a pre-ICS compatibility app and dug into the framework core source. Both answers above are sort of correct.
It basically boils down to using qualifiers. The height is defined by the dimension "action_bar_default_height"
It is defined to 48dip for default. But for -land it is 40dip and for sw600dp it is 56dip.

Currently from MySQL 8
you can set the following to a DATE

, in the Default

If you put just curdate()
it will fail. You need the extra (

Its function depends on the builders that you have in your project (they can choose to interpret clean command however they like) and whether you have auto-build turned on. If auto-build is on, invoking clean is equivalent of a clean build. First artifacts are removed, then a full build is invoked. If auto-build is off, clean will remove the artifacts and stop. You can then invoke build manually later.
Try doing this:
adb kill-server && adb start-server
(that restarts adb) Also you can try to edit an adb config file .android/adb_usb.ini
and add a line 04e8
after the header. Restart adb required for changes to take effect.

You can use now() to set the value of a datetime column, but keep in mind that you can't use that as a default value.
Recently I experienced a problem using optimization with g++
. The problem was related to a PCI card, where the registers (for command and data) were repreented by a memory address. My driver mapped the physical address to a pointer within the application and gave it to the called process, which worked with it like this:
unsigned int * pciMemory;
askDriverForMapping( & pciMemory );
...
pciMemory[ 0 ] = someCommandIdx;
pciMemory[ 0 ] = someCommandLength;
for ( int i = 0; i < sizeof( someCommand ); i++ )
pciMemory[ 0 ] = someCommand[ i ];
The card didn't act as expected. When I saw the assembly I understood that the compiler only wrote someCommand[ the last ]
into pciMemory
, omitting all preceding writes.
In conclusion: be accurate and attentive with optimization.
If you want more Thread to be created, in above case you have to repeat the code inside run method or at least repeat calling some method inside.
Try this, which will help you to call as many times you needed. It will be helpful when you need to execute your run more then once and from many place.
class A extends Thread {
public void run() {
//Code you want to get executed seperately then main thread.
}
}
Main class
A obj1 = new A();
obj1.start();
A obj2 = new A();
obj2.start();
I'm not sure how much of your "slowness" will be due to the loop you're doing to find entries with particular attribute values, but you can remove this loop by being more specific with your filter. Try this page for some guidance ... Search Filter Syntax
Well, there's nothing really that can pass through that, other than %
wildcard. It could be dangerous if you were using LIKE
statement as attacker could put just %
as login if you don't filter that out, and would have to just bruteforce a password of any of your users.
People often suggest using prepared statements to make it 100% safe, as data can't interfere with the query itself that way.
But for such simple queries it probably would be more efficient to do something like $login = preg_replace('/[^a-zA-Z0-9_]/', '', $login);
The answer which suggests something like taskkill /f /im java.exe
will probably work, but if you want to kill only one java process instead of all, I can suggest doing it with the help of window titles. Expample:
start "MyProgram" "C:/Program Files/Java/jre1.8.0_201/bin/java.exe" -jar MyProgram.jar
taskkill /F /FI "WINDOWTITLE eq MyProgram" /T
In my case I had to do this:
for index, user in enumerate(users):
table_body.append([])
table_body[index].append(user.user.id)
table_body[index].append(user.user.username)
Output:
[[1, 'john'], [2, 'bill']]
There's a trick you can do with the pre-processor.
It has the potential down sides that it will collapse white-space, and could be confusing for people reading the code.
But, it has the up side that you don't need to escape quote characters inside it.
#define QUOTE(...) #__VA_ARGS__
const char *sql_query = QUOTE(
SELECT word_id
FROM table1, table2
WHERE table2.word_id = table1.word_id
ORDER BY table1.word ASC
);
the preprocessor turns this into:
const char *sql_query = "SELECT word_id FROM table1, table2 WHERE table2.word_id = table1.word_id ORDER BY table1.word ASC";
I've used this trick when I was writing some unit tests that had large literal strings containing JSON. It meant that I didn't have to escape every quote character \".
If I were you I'd just use a scanner and use ".nextByte()". You can cast that to a char and you're good.
You have Full data + Transaction log backups, right? You can restore to another Database from backups and then sync the deleted rows back. Lots of work though...
(Have you looked at Redgate's SQL Log Rescue? Update: it's SQL Server 2000 only)
There is Log Explorer
Note that if you've merged remote branches or have local commits and want to go back to the remote HEAD you must do:
git reset --hard origin/HEAD
HEAD
alone will only refer to the local commit/merge -- several times I have forgotten that when resetting and end up with "your repository is X commits ahead.." when I fully intended to nuke ALL changes/commits and return to the remote branch.

Using svcutil, you can create interfaces and classes (data contracts) from the WSDL.
svcutil your.wsdl (or svcutil your.wsdl /l:vb if you want Visual Basic)
This will create a file called "your.cs" in C# (or "your.vb" in VB.NET) which contains all the necessary items.
Now, you need to create a class "MyService" which will implement the service interface (IServiceInterface) - or the several service interfaces - and this is your server instance.
Now a class by itself doesn't really help yet - you'll need to host the service somewhere. You need to either create your own ServiceHost instance which hosts the service, configure endpoints and so forth - or you can host your service inside IIS.
Use the -O file
option.
E.g.
wget google.com
...
16:07:52 (538.47 MB/s) - `index.html' saved [10728]
vs.
wget -O foo.html google.com
...
16:08:00 (1.57 MB/s) - `foo.html' saved [10728]
The Html.Hidden creates a hidden input but you have to specify the name and all the attributes you want to give that field and value. The Html.HiddenFor
creates a hidden input for the object that you pass to it, they look like this:
Html.Hidden("yourProperty",model.yourProperty);
Html.HiddenFor(m => m.yourProperty)
In this case the output is the same!
If you want to use loops You can try like this: (diff and cmp are much more efficient. )
while read line
do
flag = 0
while read line2
do
if ( "$line" = "$line2" )
then
flag = 1
fi
done < file1
if ( flag -eq 0 )
then
echo $line > file3
fi
done < file2
Note: The program is only to provide a basic insight into what can be done if u dont want to use system calls such as diff n comm..
The Accept Ranges
header (the bit in writeHead()
) is required for the HTML5 video controls to work.
I think instead of just blindly send the full file, you should first check the Accept Ranges
header in the REQUEST, then read in and send just that bit. fs.createReadStream
support start
, and end
option for that.
So I tried an example and it works. The code is not pretty but it is easy to understand. First we process the range header to get the start/end position. Then we use fs.stat
to get the size of the file without reading the whole file into memory. Finally, use fs.createReadStream
to send the requested part to the client.
var fs = require("fs"),
http = require("http"),
url = require("url"),
path = require("path");
http.createServer(function (req, res) {
if (req.url != "/movie.mp4") {
res.writeHead(200, { "Content-Type": "text/html" });
res.end('<video src="http://localhost:8888/movie.mp4" controls></video>');
} else {
var file = path.resolve(__dirname,"movie.mp4");
fs.stat(file, function(err, stats) {
if (err) {
if (err.code === 'ENOENT') {
// 404 Error if file not found
return res.sendStatus(404);
}
res.end(err);
}
var range = req.headers.range;
if (!range) {
// 416 Wrong range
return res.sendStatus(416);
}
var positions = range.replace(/bytes=/, "").split("-");
var start = parseInt(positions[0], 10);
var total = stats.size;
var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
var chunksize = (end - start) + 1;
res.writeHead(206, {
"Content-Range": "bytes " + start + "-" + end + "/" + total,
"Accept-Ranges": "bytes",
"Content-Length": chunksize,
"Content-Type": "video/mp4"
});
var stream = fs.createReadStream(file, { start: start, end: end })
.on("open", function() {
stream.pipe(res);
}).on("error", function(err) {
res.end(err);
});
});
}
}).listen(8888);
Update
Apple has clarified that slicing occurs independent of enabling bitcode. I've observed this in practice as well where a non-bitcode enabled app will only be downloaded as the architecture appropriate for the target device.
Original
Bitcode. Archive your app for submission to the App Store in an intermediate representation, which is compiled into 64- or 32-bit executables for the target devices when delivered.
Slicing. Artwork incorporated into the Asset Catalog and tagged for a platform allows the App Store to deliver only what is needed for installation.
The way I read this, if you support bitcode, downloaders of your app will only get the compiled architecture needed for their own device.
You can add a class to each of your .row
divs to add some space in between them like so:
.spacer {
margin-top: 40px; /* define margin as you see fit */
}
You can then use it like so:
<div class="row spacer">
<div class="span4">...</div>
<div class="span4">...</div>
<div class="span4">...</div>
</div>
<div class="row spacer">
<div class="span4">...</div>
<div class="span4">...</div>
<div class="span4">...</div>
</div>
This seems to me to be what the question is after, no need for formatters:
NSDate *date = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];
NSInteger hour = [components hour];
NSInteger minute = [components minute];
I've made similar thing with YouTube's IFRAME where the iframe is inside a grid that always changed based on portrait/landscape so this code worked for:
So the code for this question is:
// Layout resize
let height = window.innerHeight;
let width = window.document.getElementById('player').parentNode.clientWidth;
height = width / 1.77;
<div id="player"></div>
... etc ..
function onYouTubeIframeAPIReady() {
// Layout resize
let height = window.innerHeight;
let width = window.document.getElementById('player').parentNode.clientWidth;
height = width / 1.77;
player = new YT.Player('player', {
width: '100%',
height: height,
videoId: currentVideoId,
playerVars: {
'autoplay': 0,
'loop': 0,
'mute': 0,
'controls': 0,
'enablejsapi': 1,
'playsinline': 0,
'rel': 0,
'widget_referrer': 'http://my domain ...'
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange,
'onError': onError
}
});
}
$.ajax({
type: "POST",
data: {data:the_id},
url: "http://localhost/test/index.php/data/count_votes",
success: function(data){
//data will contain the vote count echoed by the controller i.e.
"yourVoteCount"
//then append the result where ever you want like
$("span#votes_number").html(data); //data will be containing the vote count which you have echoed from the controller
}
});
in the controller
$data = $_POST['data']; //$data will contain the_id
//do some processing
echo "yourVoteCount";
Clarification
i think you are confusing
{data:the_id}
with
success:function(data){
both the data
are different for your own clarity sake you can modify it as
success:function(vote_count){
$(span#someId).html(vote_count);
I know this post has been (very well) answered by Aquarelle but just in case somebody is having this issue with other tag forms with no text such as inputs i'll leave this here:
If you have an input in your form and placeholder is not showing because a white space at the beginning, this may be caused for you "value" attribute. In case you are using variables to fill the value of an input check that there are no white spaces between the commas and the variables.
example using twig for php framework symfony :
<input type="text" name="subject" value="{{ subject }}" placeholder="hello" /> <-- this is ok
<input type="text" name="subject" value" {{ subject }} " placeholder="hello" /> <-- this will not show placeholder
In this case the tag between {{ }} is the variable, just make sure you are not leaving spaces between the commas because white space is also a valid character.
For future readers!
Starting from material components android 1.2.0-alpha01, you have slider
component
ex:
<com.google.android.material.slider.Slider
android:id="@+id/slider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:valueFrom="20f"
android:valueTo="70f"
android:stepSize="10" />
Try passing width=200
as additional paramater when creating the Label.
This should work in creating label with specified width.
If you want to change it later, you can use:
label.config(width=200)
As you want to change the size of font itself you can try:
label.config(font=("Courier", 44))
Maybe a bit late but this might help others for MSSQL
;WITH RecordCount AS ( SELECT ROW_NUMBER() OVER (ORDER BY
COLUMN_NAME) AS [RowNumber] FROM TABLE_NAME ) SELECT
MAX(RowNumber) FROM RecordCount
An easier tool to monitor the tracking tags is to use the Chrome extension (probably available, or the equivalent for other browsers) - Google Tag Assistant. This will show what tags are firing, what problems it has found, and even breaks out stuff like eCommerce values for easy reading. Also works with the Google Tag Manager, and can handle multiple sets of tags on the page.
String[] a= {"tube", "are", "fun"};
Arrays.asList(a).contains("any");
According to PHPMailer Manual, full answer would be :
$mail->AddEmbeddedImage(filename, cid, name);
//Example
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');
Use Case :
$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Embedded Image: <img alt="PHPMailer" src="cid:my-attach"> Here is an image!';
If you want to display an image with a remote URL :
$mail->addStringAttachment(file_get_contents("url"), "filename");
I came here to find a way to edit the theme, but could not find it on my Mac. After a deep dive, finally I found the install place:
~/.vscode/extensions
All extensions in there!
This problem had been bugging me for years the only workaround for me was to ask our networks team to make exceptions on our firewall so that certain URL requests didn't need to be authenticated on the proxy which is not ideal.
Recently I upgraded the project to .NET 4 from 3.5 and the code just started working using the default credentials for the proxy, no hardcoding of credentials etc.
request.Proxy.Credentials = CredentialCache.DefaultCredentials;
For JQuery 1.7+ use:
$('input[type=checkbox]').on('change', function() {

});
If you want to keep your CustomView
and its xib
independent of File's Owner
, then follow these steps
File's Owner
field empty.xib
file of your CustomView
and set its Custom Class
as CustomView
(name of your custom view class)IBOutlet
in .h
file of your custom view..xib
file of your custom view, click on view and go in Connection Inspector
. Here you will all your IBOutlets which you define in .h
filein .m
file of your CustomView
class, override the init
method as follow
-(CustomView *) init{
CustomView *result = nil;
NSArray* elements = [[NSBundle mainBundle] loadNibNamed: NSStringFromClass([self class]) owner:self options: nil];
for (id anObject in elements)
{
if ([anObject isKindOfClass:[self class]])
{
result = anObject;
break;
}
}
return result;
}
Now when you want to load your CustomView
, use the following line of code
[[CustomView alloc] init];
subprocess.Popen
takes a list of arguments:
from subprocess import Popen, PIPE
process = Popen(['swfdump', '/tmp/filename.swf', '-d'], stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()
There's even a section of the documentation devoted to helping users migrate from os.popen
to subprocess
.
You can do it without modifying the XML stream: Tell the XmlReader to not be so picky.
Setting the XmlReaderSettings.ConformanceLevel
to ConformanceLevel.Fragment
will let the parser ignore the fact that there is no root node.
XmlReaderSettings settings = new XmlReaderSettings();
settings.ConformanceLevel = ConformanceLevel.Fragment;
using (XmlReader reader = XmlReader.Create(tr,settings))
{
...
}
Now you can parse something like this (which is an real time XML stream, where it is impossible to wrap with a node).

If you want to link, say, libapplejuice statically, but not, say, liborangejuice, you can link like this:
gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary
There's a caveat -- if liborangejuice
uses libapplejuice
, then libapplejuice
will be dynamically linked too.
You'll have to link liborangejuice
statically alongside with libapplejuice
to get libapplejuice
static.
And don't forget to keep -Wl,-Bdynamic
else you'll end up linking everything static, including libc
(which isn't a good thing to do).
You can try this.
Workbooks("Tire.xls").Activate
ThisWorkbook.Sheets("Sheet1").Select

Here's a version, again using the cross product logic, written in Clojure.
(defn is-left? [line point]
(let [[[x1 y1] [x2 y2]] (sort line)
[x-pt y-pt] point]
(> (* (- x2 x1) (- y-pt y1)) (* (- y2 y1) (- x-pt x1)))))
Example usage:
(is-left? [[-3 -1] [3 1]] [0 10])
true
Which is to say that the point (0, 10) is to the left of the line determined by (-3, -1) and (3, 1).
NOTE: This implementation solves a problem that none of the others (so far) does! Order matters when giving the points that determine the line. I.e., it's a "directed line", in a certain sense. So with the above code, this invocation also produces the result of true
:
(is-left? [[3 1] [-3 -1]] [0 10])
true
That's because of this snippet of code:
(sort line)
Finally, as with the other cross product based solutions, this solution returns a boolean, and does not give a third result for collinearity. But it will give a result that makes sense, e.g.:
(is-left? [[1 1] [3 1]] [10 1])
false
Using PHP's mail()
function it's possible. Remember mail function will not work on a Local server.
<?php
$to = '[email protected]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [email protected]' . "\r\n" .
'Reply-To: [email protected]' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
?>
Reference:
I got this error due to not pointing the script to the correct path. So make absolutely sure that you are pointing to the correct path in you html file.
I was using Write #1 "Print my Line" instead I tried Print #1, "Print my Line" and it give me all the data without default Quote(")
Dim strFile_Path As String
strFile_Path = ThisWorkbook.Path & "\" & "XXXX" & VBA.Format(VBA.Now, "dd-MMM-yyyy hh-mm") & ".txt"

The problem is that you used the select option, this is where you went wrong. Select signifies that a textbox or textArea has a focus. What you need to do is use change. "Fires when a new choice is made in a select element", also used like blur when moving away from a textbox or textArea.
function start(){
document.getElementById("activitySelector").addEventListener("change", addActivityItem, false);
}
function addActivityItem(){
//option is selected
alert("yeah");
}
window.addEventListener("load", start, false);
Create an initializer for it:
# config/initializers/time_formats.rb
Add something like this to it:
Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y"
And then use it the following way:
post.updated_at.to_s(:custom_datetime)
?? Your have to restart rails server for this to work.

Unique is a keyword used in the Create Table() directive to denote that a field will contain unique data, usually used for natural keys, foreign keys etc.
For example:
Create Table Employee(
Emp_PKey Int Identity(1, 1) Constraint PK_Employee_Emp_PKey Primary Key,
Emp_SSN Numeric Not Null Unique,
Emp_FName varchar(16),
Emp_LName varchar(16)
)
i.e. Someone's Social Security Number would likely be a unique field in your table, but not necessarily the primary key.
Distinct is used in the Select statement to notify the query that you only want the unique items returned when a field holds data that may not be unique.
Select Distinct Emp_LName
From Employee
You may have many employees with the same last name, but you only want each different last name.
Obviously if the field you are querying holds unique data, then the Distinct keyword becomes superfluous.
Just found the answer, in this SO question (literally, inside the question, not any answer):
SELECT @@servername
returns servername\instance as far as this is not the default instance
SELECT @@servicename
returns instance name, even if this is the default (MSSQLSERVER)
You cannot assign NULL
or 0
to a C++ std::string
object, because the object is not a pointer. This is one key difference from C-style strings; a C-style string can either be NULL
or a valid string, whereas C++ std::string
s always store some value.
There is no easy fix to this. If you'd like to reserve a sentinel value (say, the empty string), then you could do something like
const std::string NOT_A_STRING = "";
mValue = NOT_A_STRING;
Alternatively, you could store a pointer to a string so that you can set it to null:
std::string* mValue = NULL;
if (value) {
mValue = new std::string(value);
}
Hope this helps!
This rule
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o producer.o consumer.o AddRemove.o
is wrong. It says to create a file named producer.o (with -o producer.o
), but you want to create a file named main
. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET:
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o $@ producer.o consumer.o AddRemove.o
As Shahbaz rightly points out, the gmake professionals would also use $^
which expands to all the prerequisites in the rule. In general, if you find yourself repeating a string or name, you're doing it wrong and should use a variable, whether one of the built-ins or one you create.
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o $@ $^

Let's say the child view controller has a UISlider
and we want to pass the value of the slider back to the parent via a delegate.
In the child view controller's header file, declare the delegate type and its methods:
ChildViewController.h
#import <UIKit/UIKit.h>
// 1. Forward declaration of ChildViewControllerDelegate - this just declares
// that a ChildViewControllerDelegate type exists so that we can use it
// later.
@protocol ChildViewControllerDelegate;
// 2. Declaration of the view controller class, as usual
@interface ChildViewController : UIViewController
// Delegate properties should always be weak references
// See http://stackoverflow.com/a/4796131/263871 for the rationale
// (Tip: If you're not using ARC, use `assign` instead of `weak`)
@property (nonatomic, weak) id<ChildViewControllerDelegate> delegate;
// A simple IBAction method that I'll associate with a close button in
// the UI. We'll call the delegate's childViewController:didChooseValue:
// method inside this handler.
- (IBAction)handleCloseButton:(id)sender;
@end
// 3. Definition of the delegate's interface
@protocol ChildViewControllerDelegate <NSObject>
- (void)childViewController:(ChildViewController*)viewController
didChooseValue:(CGFloat)value;
@end
In the child view controller's implementation, call the delegate methods as required.
ChildViewController.m
#import "ChildViewController.h"
@implementation ChildViewController
- (void)handleCloseButton:(id)sender {
// Xcode will complain if we access a weak property more than
// once here, since it could in theory be nilled between accesses
// leading to unpredictable results. So we'll start by taking
// a local, strong reference to the delegate.
id<ChildViewControllerDelegate> strongDelegate = self.delegate;
// Our delegate method is optional, so we should
// check that the delegate implements it
if ([strongDelegate respondsToSelector:@selector(childViewController:didChooseValue:)]) {
[strongDelegate childViewController:self didChooseValue:self.slider.value];
}
}
@end
In the parent view controller's header file, declare that it implements the ChildViewControllerDelegate
protocol.
RootViewController.h
#import <UIKit/UIKit.h>
#import "ChildViewController.h"
@interface RootViewController : UITableViewController <ChildViewControllerDelegate>
@end
In the parent view controller's implementation, implement the delegate methods appropriately.
RootViewController.m
#import "RootViewController.h"
@implementation RootViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
ChildViewController *detailViewController = [[ChildViewController alloc] init];
// Assign self as the delegate for the child view controller
detailViewController.delegate = self;
[self.navigationController pushViewController:detailViewController animated:YES];
}
// Implement the delegate methods for ChildViewControllerDelegate
- (void)childViewController:(ChildViewController *)viewController didChooseValue:(CGFloat)value {
// Do something with value...
// ...then dismiss the child view controller
[self.navigationController popViewControllerAnimated:YES];
}
@end
Hope this helps!
Unfortunately, it's not in the .NET Framework itself. My wish is that you could integrate with FileZilla, but I don't think it exposes an interface. They do have scripting I think, but it won't be as clean obviously.
I've used CuteFTP in a project which does SFTP. It exposes a COM component which I created a .NET wrapper around. The catch, you'll find, is permissions. It runs beautifully under the Windows credentials which installed CuteFTP, but running under other credentials requires permissions to be set in DCOM.
There is a blog post with some C# sample code on how to do it here.
// First date of the current date
echo date('Y-m-d', mktime(0, 0, 0, date('m'), 1, date('Y')));
echo '<br />';
// Last date of the current date
echo date('Y-m-d', mktime(0, 0, 0, date('m')+1, 0, date('Y')));
The boolean builtins are capitalized: True
and False
.
Note also that you can do checker = bool(some_decision)
as a bit of shorthand -- bool
will only ever return True
or False
.
It's good to know for future reference that classes defining __nonzero__
or __len__
will be True
or False
depending on the result of those functions, but virtually every other object's boolean result will be True
(except for the None
object, empty sequences, and numeric zeros).
Performance wise StringBuffer is much better than String ; because whenever you apply concatenation on String Object then new String object are created on each concatenation.
Principal Rule : String are immutable(Non Modifiable) and StringBuffer are mutable(Modifiable)
Here is the programmatic experiment where you get the performance difference
public class Test {
public static int LOOP_ITERATION= 100000;
public static void stringTest(){
long startTime = System.currentTimeMillis();
String string = "This";
for(int i=0;i<LOOP_ITERATION;i++){
string = string+"Yasir";
}
long endTime = System.currentTimeMillis();
System.out.println(endTime - startTime);
}
public static void stringBufferTest(){
long startTime = System.currentTimeMillis();
StringBuffer stringBuffer = new StringBuffer("This");
for(int i=0;i<LOOP_ITERATION;i++){
stringBuffer.append("Yasir");
}
long endTime = System.currentTimeMillis();
System.out.println(endTime - startTime);
}
public static void main(String []args){
stringTest()
stringBufferTest();
}
}
Output of String are in my machine 14800
Output of StringBuffer are in my machine 14

If you don't see the Active Directory, it's because you did not install AD LS Users and Computer Feature. Go to Manage - Add Roles & Features. Within Add Roles and Features Wizard, on Features tab, select Remote Server Administration Tools, select - Role Admininistration Tools - Select AD DS and DF LDS Tools.
After that, you can see the PS Active Directory package.
To color each cell based on its current integer value, the following should work, if you have a recent version of Excel. (Older versions don't handle rgb as well)
Sub Colourise()
'
' Colourise Macro
'
' Colours all selected cells, based on their current integer rgb value
' For e.g. (it's a bit backward from what you might expect)
' 255 = #ff0000 = red
' 256*255 = #00ff00 = green
' 256*256*255 #0000ff = blue
' 255 + 256*256*255 #ff00ff = magenta
' and so on...
'
' Keyboard Shortcut: Ctrl+Shift+C (or whatever you want to set it to)
'
For Each cell In Selection
If WorksheetFunction.IsNumber(cell) Then
cell.Interior.Color = cell.Value
End If
Next cell
End Sub
If instead of a number you have a string then you can split the string into three numbers and combine them using rgb().
You also can do it with functional programming:
from functools import reduce
reduce(lambda df1, df2: df1.merge(df2, "outer"), mydfs)
The full procedure that worked for me to transfer ALL branches and tags is, combining the answers of @vikas027 and @kumarahul:
~$ git clone <url_of_old_repo>
~$ cd <name_of_old_repo>
~$ git remote add new-origin <url_of_new_repo>
~$ git push new-origin --mirror
~$ git push new-origin refs/remotes/origin/*:refs/heads/*
~$ git push new-origin --delete HEAD
The last step is because a branch named HEAD
appears in the new remote due to the wildcard
I also had some trouble with my scrollable modals, so I did something like this:
$('.modal').on('shown.bs.modal', function () {
$('body').addClass('modal-open');
// BS adds some padding-right to acomodate the scrollbar at right
$('body').removeAttr('style');
})
$(".modal [data-toggle='modal']").click(function(){
$(this).closest(".modal").modal('hide');
});
It will serve for any modal whithin a modal that comes to appear. Note that the first its closed so the second can appear. No changes in the Bootstrap structure.
This question (Stream Way to get index of first element matching boolean) has marked the current question as a duplicate, so I can not answer it there; I am answering it here.
Here is a generic solution to get the matching index that does not require an external library.
If you have a list.
public static <T> int indexOf(List<T> items, Predicate<T> matches) {
return IntStream.range(0, items.size())
.filter(index -> matches.test(items.get(index)))
.findFirst().orElse(-1);
}
And call it like this:
int index = indexOf(myList, item->item.getId()==100);
And if using a collection, try this one.
public static <T> int indexOf(Collection<T> items, Predicate<T> matches) {
int index = -1;
Iterator<T> it = items.iterator();
while (it.hasNext()) {
index++;
if (matches.test(it.next())) {
return index;
}
}
return -1;
}
The only way to make this work for IE is to set you web server to treat requests for *.ico to call your server side scripting language (PHP, .NET, etc). Also setup *.ico to redirect to a single script and have this script deliver the correct favicon file. I'm sure there is still going to be some interesting issues with cache if you want to be able to bounce back and forth in the same browser between different favicons.
After a bit of time (and more searching), I found this blog entry by Jomo Fisher.
One of the recent problems we’ve seen is that, because of the support for side-by-side runtimes, .NET 4.0 has changed the way that it binds to older mixed-mode assemblies. These assemblies are, for example, those that are compiled from C++\CLI. Currently available DirectX assemblies are mixed mode. If you see a message like this then you know you have run into the issue:
Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.
[Snip]
The good news for applications is that you have the option of falling back to .NET 2.0 era binding for these assemblies by setting an app.config flag like so:
<startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup>
So it looks like the way the runtime loads mixed-mode assemblies has changed. I can't find any details about this change, or why it was done. But the useLegacyV2RuntimeActivationPolicy
attribute reverts back to CLR 2.0 loading.
