Even with a default value, you can always override the column data with null
.
The NOT NULL
restriction won't let you update that row after it was created with null
value
Alter TABLE 'TARGET' add 'ShouldAddColumn' Integer Not Null default "0"
MYSQL IS NOT NULL WITH JOINS AND SELECT, INSERT INTO, DELETE & LOGICAL OPERATOR LIKE OR , NOT
Using IS NOT NULL On Join Conditions
SELECT * FROM users
LEFT JOIN posts ON post.user_id = users.id
WHERE user_id IS NOT NULL;
Using IS NOT NULL With AND Logical Operator
SELECT * FROM users
WHERE email_address IS NOT NULL
AND mobile_number IS NOT NULL;
Using IS NOT NULL With OR Logical Operator
SELECT * FROM users
WHERE email_address IS NOT NULL
OR mobile_number IS NOT NULL;
ISNULL(
case textcolum1
WHEN '' THEN NULL
ELSE textcolum1
END
,textcolum2) textcolum1
I typically use something like this:
if exists (select * from dbo.sysobjects
where id = object_id(N'dbo.MyView') and
OBJECTPROPERTY(id, N'IsView') = 1)
drop view dbo.MyView
go
create view dbo.MyView [...]
In my case my request object inherited from base object. Without knowingly I added a property with int? in my request object and my base object also has same property ( same name ) with int datatype. I noticed this and deleted the property which I added in request object and after that it worked fine.

Try to uninstall angular and then reinstall
npm uninstall --save @angular/(then whatever component you want deleted)
after that, a box with babyblue color border will appear with suggestion to update and install angular back up.
You are just supposed to provide the predict
method with the same 2D array, but with one value that you want to process (or more). In short, you can just replace
[0.58,0.76]
With
[[0.58,0.76]]
And it should work.
EDIT: This answer became popular so I thought I'd add a little more explanation about ML. The short version: we can only use predict
on data that is of the same dimensionality as the training data (X
) was.
In the example in question, we give the computer a bunch of rows in X
(with 2 values each) and we show it the correct responses in y
. When we want to predict
using new values, our program expects the same - a bunch of rows. Even if we want to do it to just one row (with two values), that row has to be part of another array.
You must setup postgresql-server-dev-X.Y, where X.Y. your's servers version, and it will install libpq-dev and other servers variables at modules for server side developing. In my case it was
apt-get install postgresql-server-dev-9.5
Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: libmysqlclient18 mysql-common Use 'apt-get autoremove' to remove them. The following extra packages will be installed:
libpq-dev Suggested packages: postgresql-doc-10 The following NEW packages will be installed: libpq-dev postgresql-server-dev-9.5
In your's case
sudo apt-get install postgresql-server-dev-X.Y
sudo apt-get install python-psycopg2
ActionBar actionBar;

You can use the search function available in the location object. The search function gives the parameter part of the URL. Details can be found in Location Object.
You will have to parse the resulting string for getting the variables and their values, e.g. splitting them on '='.
If you're on MacOS and using homebrew I found this answer extremely helpful:
https://stackoverflow.com/a/27708774/4062901
For me, my server was running but because of an upgrade I was having issues connecting (note: I use brew services). If Postgres is running, try cat /usr/local/var/postgres/server.log
and see what the logs say. My error was a migration, not a connection issue.
Also after the manual migration they propose (which does work but) I found there was no longer a table for my user. Try this command to fix that: createdb

I lack the reputation to comment but ctime from Marlon Abeykoons response did not give the correct result for me. Using mtime does the trick though. (key=os.path.getmtime))
import glob
import os
list_of_files = glob.glob('/path/to/folder/*') # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getmtime)
print latest_file
I found two answers for that problem:
python os.path.getctime max does not return latest Difference between python - getmtime() and getctime() in unix system
A space in a CSS selector selects child elements.
.btn input
This is basically what you wrote and it would select <input>
elements within any element that has the btn
class.
I think you're looking for
input[disabled].btn:hover, input[disabled].btn:active, input[disabled].btn:focus
This would select <input>
elements with the disabled
attribute and the btn
class in the three different states of hover
, active
and focus
.
Using Desandro's imagesloaded plugin
1 - hide images in css:
#content img {
display:none;
}
2 - fade in images on load with javascript:
var imgLoad = imagesLoaded("#content");
imgLoad.on( 'progress', function( instance, image ) {
$(image.img).fadeIn();
});
As environments are inherited from the parent process, you could write an add-in for Visual Studio that modifies its environment variables before you perform the start. I am not sure how easy that would be to put into your process.
Using pure JavaScript.It's very easy using local storage.

localStorage.setItem("txtValue2", mobile);
localStorage.setItem("txtValue3", telephone);

You have forgotten a *
between -3.7
and (prof[x])
.
Thus:
for x in range(len(prof)):
PB = 2.25 * (1 - math.pow(math.e, (-3.7 * (prof[x])/2.25))) * (math.e, (0/2.25)))
Also, there seems to be missing an (
as I count 6 times (
and 7 times )
, and I think (math.e, (0/2.25))
is missing a function call (probably math.pow
, but thats just a wild guess).
It could be your Hibernate entity relationship causing the issue...simply stop lazy loading of that related entity...for example...I resolved below by setting lazy="false" for customerType.
<class name="Customer" table="CUSTOMER">
<id name="custId" type="long">
<column name="CUSTID" />
<generator class="assigned" />
</id>
<property name="name" type="java.lang.String">
<column name="NAME" />
</property>
<property name="phone" type="java.lang.String">
<column name="PHONE" />
</property>
<property name="pan" type="java.lang.String">
<column name="PAN" />
</property>
<many-to-one name="customerType" not-null="true" lazy="false"></many-to-one>
</class>
</hibernate-mapping>
insert byte to specific place.

If you prefer shorter if else statement, you can use this shorthand:
<%= typeof(id)!== 'undefined' ? id : '' %>
It means display the id if is valid and blank if it wasn't.

It is now this For swift 3,
let button = (sender as AnyObject)
button.setTitle("Your text", for: .normal)
(The constant declaration of the variable is not necessary just make sure you use the sender from the button like this) :
(sender as AnyObject).setTitle("Your text", for: .normal)
Remember this is used inside the IBAction of your button.
Hey! I'm the developer of wxMathPlot! The project is active: I just took a long time to get a new release, because the code needed a partial rewriting to introduce new features. Take a look to the new 0.1.0 release: it is a great improvement from old versions. Anyway, it doesn't provide 3D (even if I always thinking about it...).
Try this first, you may be passing a Null Model:
@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
<label for="Image">Change picture</label>
}
else
{
<label for="Image">Add picture</label>
}
Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.
<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>
When doing Flask Basic auth I got this error and then I realized I had wrapped_view(**kwargs) and it worked after changing it to wrapped_view(*args, **kwargs).
I know this is an old post, but I just came across this problem on Windows 10 running Python 3.8.5 and Git 2.28.0.windows.1
Somehow I had several different 2.7x versions of Python installed as well. I removed every version of Python (3x and 2x), downloaded the official installer here, installed 3.8.5 fresh (just used the defaults) which installed Python 3.8.5 at this location:
C:\Users\(my username)\AppData\Local\Programs\Python\Python38
Then to get the command python
to work in my git bash shell, I had to manually add the path to Python38
to my path variable following the instructions listed here. This is important to note because on the python installer at the bottom of the first modal that comes up it asks if you want to add the python path to your PATH
environment variable. I clicked the checkbox next to this but it didn't actually add the path, hence the need to manually add the path to my PATH
environment variable.
Now using my gitbash shell I can browse to a directory with a python script in it and just type python theScriptName.py
and it runs no problem.
I wanted to post this because this is all I had to do to get my gitbash shell to allow me to run python scripts. I think there might have been some updates so I didn't need to do any of the other solutions listed here. At any rate, this is another thing to try if you are having issues running python scripts in your gitbash shell on a Windows 10 machine.
Enjoy.
I think you'll get what you want with the -maxdepth 1
option, based on your current command structure. If not, you can try looking at the man page for find
.
Relevant entry (for convenience's sake):
-maxdepth levels
Descend at most levels (a non-negative integer) levels of direc-
tories below the command line arguments. `-maxdepth 0' means
only apply the tests and actions to the command line arguments.
Your options basically are:
# Do NOT show hidden files (beginning with ".", i.e., .*):
find DirsRoot/* -maxdepth 0 -type f
Or:
# DO show hidden files:
find DirsRoot/ -maxdepth 1 -type f
You should look for a hosting company that provides such feature, but standard simple static+PHP+MySQL hosting won't let you use node.js.
You need either find a hosting designed for node.js or buy a Virtual Private Server and install it yourself.
It can also be used as below:
from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)
The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-"
for a red line, or by explicitely stating the color
argument.
import matplotlib.pyplot as plt
plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line
plt.show()
See also the plot command's documentation.
In case you already have a line with a certain color, you can change that with the lines2D.set_color()
method.
line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")
import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line
plt.show()
If you want to change this color later on, you can do so by
plt.gca().get_lines()[0].set_color("black")
This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them
for ax in plt.gcf().axes:
ax.get_lines()[0].set_color("black")
and if you have more lines you can loop over them as well.
UPDATE: (5 years later)
Note: If you decide to use Kappa Architecture (Event Sourcing + CQRS), then you do not need updated date at all. Since your data is an immutable, append-only event log, you only ever need event created date. Similar to the Lambda Architecture, described below. Then your application state is a projection of the event log (derived data). If you receive a subsequent event about existing entity, then you'll use that event's created date as updated date for your entity. This is a commonly used (and commonly misunderstood) practice in miceroservice systems.
UPDATE: (4 years later)
If you use ObjectId
as your _id
field (which is usually the case), then all you need to do is:
let document = {
updatedAt: new Date(),
}
Check my original answer below on how to get the created timestamp from the _id
field.
If you need to use IDs from external system, then check Roman Rhrn Nesterov's answer.
UPDATE: (2.5 years later)
You can now use the #timestamps option with mongoose version >= 4.0.
let ItemSchema = new Schema({
name: { type: String, required: true, trim: true }
},
{
timestamps: true
});
If set timestamps, mongoose assigns createdAt
and updatedAt
fields to your schema, the type assigned is Date
.
You can also specify the timestamp fileds' names:
timestamps: { createdAt: 'created_at', updatedAt: 'updated_at' }
Note: If you are working on a big application with critical data you should reconsider updating your documents. I would advise you to work with immutable, append-only data (lambda architecture). What this means is that you only ever allow inserts. Updates and deletes should not be allowed! If you would like to "delete" a record, you could easily insert a new version of the document with some
timestamp
/version
filed and then set adeleted
field totrue
. Similarly if you want to update a document – you create a new one with the appropriate fields updated and the rest of the fields copied over.Then in order to query this document you would get the one with the newest timestamp or the highest version which is not "deleted" (thedeleted
field is undefined or false`).Data immutability ensures that your data is debuggable – you can trace the history of every document. You can also rollback to previous version of a document if something goes wrong. If you go with such an architecture
ObjectId.getTimestamp()
is all you need, and it is not Mongoose dependent.
ORIGINAL ANSWER:
If you are using ObjectId as your identity field you don't need created_at
field. ObjectIds have a method called getTimestamp()
.
ObjectId("507c7f79bcf86cd7994f6c0e").getTimestamp()
This will return the following output:
ISODate("2012-10-15T21:26:17Z")
More info here How do I extract the created date out of a Mongo ObjectID
In order to add updated_at
filed you need to use this:
var ArticleSchema = new Schema({
updated_at: { type: Date }
// rest of the fields go here
});
ArticleSchema.pre('save', function(next) {
this.updated_at = Date.now();
next();
});
This should do it:
<StackPanel>
<TextBox x:Name="TheTextBox" />
<Button Content="Click Me">
<Button.Style>
<Style TargetType="Button">
<Setter Property="IsEnabled" Value="True" />
<Style.Triggers>
<DataTrigger Binding="{Binding Text, ElementName=TheTextBox}" Value="">
<Setter Property="IsEnabled" Value="False" />
</DataTrigger>
</Style.Triggers>

This is a bit dated but there may be others looking for answers to the same question. You should think about what protection spaces make sense for your APIs. For example, you may want to identify and authenticate client application access to your APIs to restrict their use to known, registered client applications. In this case, you can use the Basic
authentication scheme with the client identifier as the user-id and client shared secret as the password. You don't need proprietary authentication schemes just clearly identify the one(s) to be used by clients for each protection space. I prefer only one for each protection space but the HTTP standards allow both multiple authentication schemes on each WWW-Authenticate header response and multiple WWW-Authenticate headers in each response; this will be confusing for API clients which options to use. Be consistent and clear then your APIs will be used.
In my case, I needed to retrieve the username to enable the script to change the path, ie. c:\users\%username%\
. I needed to start the script by changing the path to the users desktop. I was able to do this, with help from above and elsewhere, by using the get-location applet.
You may have another, or even better way to do it, but this worked for me:
$Path = Get-Location
Set-Location $Path\Desktop
Using the ES2015 Spread operator:
[...Array(n)].map()
const res = [...Array(10)].map((_, i) => {
return i * 10;
});
// as a one liner
const res = [...Array(10)].map((_, i) => i * 10);
Or if you don't need the result:
[...Array(10)].forEach((_, i) => {
console.log(i);
});
// as a one liner
[...Array(10)].forEach((_, i) => console.log(i));
Or using the ES2015 Array.from operator:
Array.from(...)
const res = Array.from(Array(10)).map((_, i) => {
return i * 10;
});
// as a one liner
const res = Array.from(Array(10)).map((_, i) => i * 10);
Note that if you just need a string repeated you can use String.prototype.repeat.
console.log("0".repeat(10))
// 0000000000
Its a start, it can list:
models = Dir.new("#{RAILS_ROOT}/app/models").entries

If you NPM those modules you can serve them using static redirect.
First install the packages:
npm install jquery
npm install bootstrap
Then on the server.js:
var express = require('express');
var app = express();
// prepare server
app.use('/api', api); // redirect API calls
app.use('/', express.static(__dirname + '/www')); // redirect root
app.use('/js', express.static(__dirname + '/node_modules/bootstrap/dist/js')); // redirect bootstrap JS
app.use('/js', express.static(__dirname + '/node_modules/jquery/dist')); // redirect JS jQuery
app.use('/css', express.static(__dirname + '/node_modules/bootstrap/dist/css')); // redirect CSS bootstrap
Then, finally, at the .html:
<link rel="stylesheet" href="/css/bootstrap.min.css">
<script src="/js/jquery.min.js"></script>
<script src="/js/bootstrap.min.js"></script>
I would not serve pages directly from the folder where your server.js file is (which is usually the same as node_modules) as proposed by timetowonder, that way people can access your server.js file.
Of course you can simply download and copy & paste on your folder, but with NPM you can simply update when needed... easier, I think.
First of all, don’t fix it this way
if ( ! $scope.$$phase) {
$scope.$apply();
}
It does not make sense because $phase is just a boolean flag for the $digest cycle, so your $apply() sometimes won’t run. And remember it’s a bad practice.
Instead, use $timeout
$timeout(function(){
// Any code in here will automatically have an $scope.apply() run afterwards
$scope.myvar = newValue;
// And it just works!
});
If you are using underscore or lodash, you can use defer():
_.defer(function(){
$scope.$apply();
});
You can try
if(dtOne.Year == dtTwo.Year && dtOne.Month == dtTwo.Month && dtOne.Day == dtTwo.Day)

My latest issue was how to integrate CKFinder for image upload in CKEditor. Here the solution.
Download CKEditor and extract in your web folder root.
Download CKFinder and extract withing ckeditor folder.
Then add references to the CKEditor, CKFinder and put
<CKEditor:CKEditorControl ID="CKEditorControl1" runat="server"></CKEditor:CKEditorControl>
to your aspx page.
In code behind page OnLoad event add this code snippet
protected override void OnLoad(EventArgs e)
{
CKFinder.FileBrowser _FileBrowser = new CKFinder.FileBrowser();
_FileBrowser.BasePath = "ckeditor/ckfinder/";
_FileBrowser.SetupCKEditor(CKEditorControl1);
}
Edit Confic.ascx file.
public override bool CheckAuthentication()
{
return true;
}
// Perform additional checks for image files.
SecureImageUploads = true;

I'd suggest, to add in the nugget package:
Install-Package OpenDialog
Then the way to used it is:
Gat.Controls.OpenDialogView openDialog = new Gat.Controls.OpenDialogView();
Gat.Controls.OpenDialogViewModel vm = (Gat.Controls.OpenDialogViewModel)openDialog.DataContext;
vm.IsDirectoryChooser = true;
vm.Show();
WPFLabel.Text = vm.SelectedFilePath.ToString();

When the using()

Note you can add the Microsoft.AspNetCore.WebUtilities
nuget package from Microsoft and then use this to append values to query string:
QueryHelpers.AddQueryString(longurl, "action", "login1")
QueryHelpers.AddQueryString(longurl, new Dictionary<string, string> { { "action", "login1" }, { "attempts", "11" } });
in your css :
#txtComputer {

I understand you want to display using HTMl but you can also open the PDF file using php by pointing out the path and the browser will render it in a few simple steps
<?php
$your_file_name = "url_here";
//Content type and this case its a PDF
header("Content-type: application/pdf");
header("Content-Length: " . filesize($your_file_name ));
//Display the file
readfile($your_file_name );
?>
Here is a solution worked for me and also, I found all of the above solutions are correct. My excel model got corrupted and which is why my code (similar to this one) stopped working. Here is what worked for me and is working every time-
Your compound PRIMARY KEY
specification already does what you want. Omit the line that's giving you a syntax error, and omit the redundant CONSTRAINT
(already implied), too:
CREATE TABLE tags
(
question_id INTEGER NOT NULL,
tag_id SERIAL NOT NULL,
tag1 VARCHAR(20),
tag2 VARCHAR(20),
tag3 VARCHAR(20),
PRIMARY KEY(question_id, tag_id)
);
NOTICE: CREATE TABLE will create implicit sequence "tags_tag_id_seq" for serial column "tags.tag_id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "tags_pkey" for table "tags"
CREATE TABLE
pg=> \d tags
Table "public.tags"
Column | Type | Modifiers
-------------+-----------------------+-------------------------------------------------------
question_id | integer | not null
tag_id | integer | not null default nextval('tags_tag_id_seq'::regclass)
tag1 | character varying(20) |
tag2 | character varying(20) |
tag3 | character varying(20) |
Indexes:
"tags_pkey" PRIMARY KEY, btree (question_id, tag_id)
NumberFormat and DecimalFormat are definitely what you want. Also, note the NumberFormat.setRoundingMode()
method. You can use it to control how rounding or truncation is applied during formatting.
Go to Tools > Options. In the tree on the left, select SQL Server Object Explorer. Set the option "Value for Edit Top Rows command" to 0. It'll now allow you to view and edit the entire table from the context menu.
As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().
Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static
for the example. Once it's done, add this line in your server code:
app.use("/static", express.static('./static/'));
This will effectively serve every file in your "static" folder via the /static route.
Querying your index.js file in the client thus becomes:
<script src="static/index.js"></script>
input[disabled], input[disabled]:hover { background-color:#444; }
You can try viewport units (CSS3):
div {
height: 95vh;
width: 95vw;
}
Per Josh Bloch - Item 65: Don't ignore Exceptions of Effective Java:
use plt.figure(dpi=1200)

If you are in taxonomy page.
That's how you get all details about the taxonomy.
get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
This is how you get the taxonomy id
$termId = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) )->term_id;
But if you are in post page (taxomony -> child)
$terms = wp_get_object_terms( get_queried_object_id(), 'taxonomy-name');
$term_id = $terms[0]->term_id;
I have found Adobe Dreamweaver to be quite good at that. However, it's not free.
--save-dev
saves semver spec into "devDependencies" array in your package descriptor file, --save
saves it into "dependencies" instead.
None of the above worked.. but installing a new version of MySQL did the trick.
package com.programmingfree.springshop.controller;

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details

Why not:
onItemClick: function (event) {
event.currentTarget.style.backgroundColor = '#ccc';
},
render: function() {
return (
<div>
<ul>
<li onClick={this.onItemClick}>Component 1</li>
</ul>
</div>
);
}
And if you want to be more React-ive about it, you might want to set the selected item as state of its containing React component, then reference that state to determine the item's color within render
:
onItemClick: function (event) {
this.setState({ selectedItem: event.currentTarget.dataset.id });
//where 'id' = whatever suffix you give the data-* li attribute
},
render: function() {
return (
<div>
<ul>
<li onClick={this.onItemClick} data-id="1" className={this.state.selectedItem == 1 ? "on" : "off"}>Component 1</li>
<li onClick={this.onItemClick} data-id="2" className={this.state.selectedItem == 2 ? "on" : "off"}>Component 2</li>
<li onClick={this.onItemClick} data-id="3" className={this.state.selectedItem == 3 ? "on" : "off"}>Component 3</li>
</ul>
</div>
);
},
You'd want to put those <li>
s into a loop, and you need to make the li.on
and li.off
styles set your background-color
.
Here's my reason why ...
I have populated a JavaFX ComboBox with the values of an Enum. I have an interface, Identifiable (specifying one method: identify), that allows me to specify how any object identifies itself to my application for searching purposes. This interface enables me to scan lists of any type of objects (whichever field the object may use for identity) for an identity match.
I'd like to find a match for an identity value in my ComboBox list. In order to use this capability on my ComboBox containing the Enum values, I must be able to implement the Identifiable interface in my Enum (which, as it happens, is trivial to implement in the case of an Enum).
@Controller
is used to mark classes as Spring MVC Controller.@RestController
is a convenience annotation that does nothing more than adding the @Controller
and @ResponseBody
annotations (see: Javadoc)So the following two controller definitions should do the same
@Controller
@ResponseBody
public class MyController { }
@RestController
public class MyRestController { }
NSData *imageData = UIImagePNGRepresentation(myImage.image);
Whilst the listed answer is correct, may I suggest that if your column is to hold case sensitive strings you read the documentation and alter your table definition accordingly.
In my case this amounted to defining my column as:
`tag` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT ''
This is in my opinion preferential to adjusting your queries.
Since you are using jQuery, how about using a trigger-reset:
$(document).ready(function(){
$('#shares').trigger(':reset');
});

Keys helps React identify which items have changed/added/removed and should be given to the elements inside the array to give the elements a stable identity.
With that in mind, there are basically three different strategies as described bellow:
As React Documentation explains, we need to give stable identity to the elements and because of that, carefully choose the strategy that best suits your needs:
As we can see also in React Documentation, is not recommended the use of index for keys "if the order of items may change. This can negatively impact performance and may cause issues with component state".
In case of static elements like tables, lists, etc, I recommend using a tool called shortid.
1) Install the package using NPM/YARN:
npm install shortid --save
2) Import in the class file you want to use it:
import shortid from 'shortid';
2) The command to generate a new id is shortid.generate().
3) Example:
renderDropdownItems = (): React.ReactNode => {
const { data, isDisabled } = this.props;
const { selectedValue } = this.state;
const dropdownItems: Array<React.ReactNode> = [];
if (data) {
data.forEach(item => {
dropdownItems.push(
<option value={item.value} key={shortid.generate()}>
{item.text}
</option>
);
});
}
return (
<select
value={selectedValue}
onChange={this.onSelectedItemChanged}
disabled={isDisabled}
>
{dropdownItems}
</select>
);
};
IMPORTANT: As React Virtual DOM relies on the key, with shortid every time the element is re-rendered a new key will be created and the element will loose it's html state like focus or cursor position. Consider this when deciding how the key will be generated as the strategy above can be useful only when you are building elements that won't have their values changed like lists or read only fields.
If the element is sortable and you have a unique ID of the item, combine it with some extra string (in case you need to have the same information twice in a page). This is the most recommended scenario.
Example:
renderDropdownItems = (): React.ReactNode => {
const elementKey:string = 'ddownitem_';
const { data, isDisabled } = this.props;
const { selectedValue } = this.state;
const dropdownItems: Array<React.ReactNode> = [];
if (data) {
data.forEach(item => {
dropdownItems.push(
<option value={item.value} key={${elementKey}${item.id}}>
{item.text}
</option>
);
});
}
return (
<select
value={selectedValue}
onChange={this.onSelectedItemChanged}
disabled={isDisabled}
>
{dropdownItems}
</select>
);
};
As a last resort, for editable (but non sortable) fields like input, you can use some the index with some starting text as element key cannot be duplicated.
Example:
renderDropdownItems = (): React.ReactNode => {
const elementKey:string = 'ddownitem_';
const { data, isDisabled } = this.props;
const { selectedValue } = this.state;
const dropdownItems: Array<React.ReactNode> = [];
if (data) {
data.forEach((item:any index:number) => {
dropdownItems.push(
<option value={item.value} key={${elementKey}${index}}>
{item.text}
</option>
);
});
}
return (
<select
value={selectedValue}
onChange={this.onSelectedItemChanged}
disabled={isDisabled}
>
{dropdownItems}
</select>
);
};
Hope this helps.
If you mean to change default directory for "Node.js command prompt", when you launch it, then (Windows case)
change the default path in the row which looks like
if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
with your path. It could be for example
if "%CD%\"=="%~dp0" cd /d "c://MyDirectory/"
if you mean to change directory once when you launched "Node.js command prompt", then execute the following command in the Node.js command prompt:
cd c:/MyDirectory/
Others Answers Are Correct But for More Detail check this Post Pull to Refresh
Enable refreshing in Storyboard
When you’re working with a UITableViewController, the solution is fairly simple: First, Select the table view controller in your storyboard, open the attributes inspector, and enable refreshing:
A UITableViewController comes outfitted with a reference to a UIRefreshControl out of the box. You simply need to wire up a few things to initiate and complete the refresh when the user pulls down.
Override viewDidLoad()
In your override of viewDidLoad(), add a target to handle the refresh as follows:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.refreshControl?.addTarget(self, action: "handleRefresh:", forControlEvents: UIControlEvents.ValueChanged)
}
refreshControl.endRefreshing()

If you want to access a property from inside a class you should:
private $classNumber = 8;
The data returned by the JSON is in json format : which is simply an arrays of values. Thats why you are seeing [object Object],[object Object],[object Object].
You have to iterate through that values to get actuall value. Like the following
jQuery provides $.each() for iterations, so you could also do this:
$.getJSON("url_with_json_here", function(data){
$.each(data, function (linktext, link) {
console.log(linktext);
console.log(link);
});
});
Now just create an Hyperlink using that info.
To do this without any headache:
git status
, let's say branch "development".git clone
the project from repository.git checkout development
.rsync
, excluding .git folder: rsync -azv --exclude '.git' gitrepo1 newrepo/gitrepo1
. You don't have to do this with rsync
of course, but it does it so smooth.The benefit of this approach: you are good to continue exactly where you left off: your older branch, unstaged changes, etc.
You can use this code for generating has code for a given string.
int hash = 7;
for (int i = 0; i < strlen; i++) {
hash = hash*31 + charAt(i);
}
ASP.Net Web API has Authorization Server build-in already. You can see it inside Startup.cs when you create a new ASP.Net Web Application with Web API template.
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
// In production mode set AllowInsecureHttp = false
AllowInsecureHttp = true
};
All you have to do is to post URL encoded username and password inside query string.
/Token/userName=johndoe%40example.com&password=1234&grant_type=password

Because present version of matplotlib.pylab.scatter
support assigning: array of colour name string, array of float number with colour map, array of RGB or RGBA.
this answer is dedicate to @Oxinabox's endless passion for correcting the 2013 version of myself in 2015.
you have two option of using scatter command with multiple colour in a single call.
as pylab.scatter
command support use RGBA array to do whatever colour you want;
back in early 2013, there is no way to do so, since the command only support single colour for the whole scatter point collection. When I was doing my 10000-line project I figure out a general solution to bypass it. so it is very tacky, but I can do it in whatever shape, colour, size and transparent. this trick also could be apply to draw path collection, line collection....
the code is also inspired by the source code of pyplot.scatter
, I just duplicated what scatter does without trigger it to draw.
the command pyplot.scatter
return a PatchCollection
Object, in the file "matplotlib/collections.py" a private variable _facecolors
in Collection
class and a method set_facecolors
.
so whenever you have a scatter points to draw you can do this:
# rgbaArr is a N*4 array of float numbers you know what I mean
# X is a N*2 array of coordinates
# axx is the axes object that current draw, you get it from
# axx = fig.gca()
# also import these, to recreate the within env of scatter command
import matplotlib.markers as mmarkers
import matplotlib.transforms as mtransforms
from matplotlib.collections import PatchCollection
import matplotlib.markers as mmarkers
import matplotlib.patches as mpatches
# define this function
# m is a string of scatter marker, it could be 'o', 's' etc..
# s is the size of the point, use 1.0
# dpi, get it from axx.figure.dpi
def addPatch_point(m, s, dpi):
marker_obj = mmarkers.MarkerStyle(m)
path = marker_obj.get_path()
trans = mtransforms.Affine2D().scale(np.sqrt(s*5)*dpi/72.0)
ptch = mpatches.PathPatch(path, fill = True, transform = trans)
return ptch
patches = []
# markerArr is an array of maker string, ['o', 's'. 'o'...]
# sizeArr is an array of size float, [1.0, 1.0. 0.5...]
for m, s in zip(markerArr, sizeArr):
patches.append(addPatch_point(m, s, axx.figure.dpi))
pclt = PatchCollection(
patches,
offsets = zip(X[:,0], X[:,1]),
transOffset = axx.transData)
pclt.set_transform(mtransforms.IdentityTransform())
pclt.set_edgecolors('none') # it's up to you
pclt._facecolors = rgbaArr
# in the end, when you decide to draw
axx.add_collection(pclt)
# and call axx's parent to draw_idle()
Another option would be file_get_contents()
:
// $xml_str = your xml
// $url = target url
$post_data = array('xml' => $xml_str);
$stream_options = array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded' . "\r\n",
'content' => http_build_query($post_data)));
$context = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);
You could just use an even simpler typedef
:
typedef char *string;
Then, your malloc would look like a usual malloc:
string s = malloc(maxStringLength);
Set up a simple repository using a web server with its default configuration. The key is the directory structure. The documentation does not mention it explicitly, but it is the same structure as a local repository.
To set up an internal repository just requires that you have a place to put it, and then start copying required artifacts there using the same layout as in a remote repository such as repo.maven.apache.org. Source
Add a file to your repository like this:
mvn install:install-file \
-Dfile=YOUR_JAR.jar -DgroupId=YOUR_GROUP_ID
-DartifactId=YOUR_ARTIFACT_ID -Dversion=YOUR_VERSION \
-Dpackaging=jar \
-DlocalRepositoryPath=/var/www/html/mavenRepository
If your domain is example.com
and the root directory of the web server is located at /var/www/html/
, then maven can find "YOUR_JAR.jar" if configured with <url>http://example.com/mavenRepository</url>
.
With macros!
#include<stdio.h>
#define x001(a) a
#define x002(a) x001(a);x001(a)
#define x004(a) x002(a);x002(a)
#define x008(a) x004(a);x004(a)

return 0;
}
For macOS I use two commands together to show information about the processes listening on the machine and process connecting to remote servers. In other words, to check the listening ports and the current (TCP) connections on a host you could use the two following commands together
1. netstat -p tcp -p udp
2. lsof -n -i4TCP -i4UDP
Thought I would add my input, hopefully it can end up helping someone.
You can check if you got your remote setup right and have the proper permissions with
git ls-remote origin
if you called your remote "origin". If you get an error you probably don't have your security set up correctly such as uploading your public key to github for example. If things are setup correctly, you will get a list of the remote references. Now
git fetch origin
will work barring any other issues like an unplugged network cable.
Once you have that done, you can get any branch you want that the above command listed with
git checkout some-branch
this will create a local branch of the same name as the remote branch and check it out.
This works on Windows:
java -cp "lib/*" %MAINCLASS%
where %MAINCLASS%
of course is the class containing your main method.
Alternatively:
java -cp "lib/*" -jar %MAINJAR%
where %MAINJAR%
is the jar file to launch via its internal manifest.
EDIT: Updated for jQuery 1.8
Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: Added code to make it a jQuery function.
For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
'-moz-transform' : 'rotate('+ degrees +'deg)',
'-ms-transform' : 'rotate('+ degrees +'deg)',
'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.
Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.
Here is a jsFiddle.
If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.
HTML
<div class="rotate">
<h1>Rotatey text</h1>
</div>
CSS
/* Totally for style */
.rotate {
background: #F02311;
color: #FFF;
width: 200px;
height: 200px;
text-align: center;
font: normal 1em Arial;
position: relative;
top: 50px;
left: 50px;
}
/* The real code */
.rotated {
-webkit-transform: rotate(45deg); /* Chrome, Safari 3.1+ */
-moz-transform: rotate(45deg); /* Firefox 3.5-15 */
-ms-transform: rotate(45deg); /* IE 9 */
-o-transform: rotate(45deg); /* Opera 10.50-12.00 */
transform: rotate(45deg); /* Firefox 16+, IE 10+, Opera 12.10+ */
}
jQuery
Make sure these are wrapped in $(document).ready
$('.rotate').click(function() {
$(this).toggleClass('rotated');
});
Custom intervals
var rotation = 0;
$('.rotate').click(function() {
rotation += 5;
$(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
'-moz-transform' : 'rotate('+ rotation +'deg)',
'-ms-transform' : 'rotate('+ rotation +'deg)',
'transform' : 'rotate('+ rotation +'deg)'});
});
Latest version of Notepad++ got a new built-in plugin manager which works nicely.
There is no CREATE TABLE IF NOT EXISTS... but you can write a simple procedure for that, something like:
CREATE OR REPLACE FUNCTION prc_create_sch_foo_table() RETURNS VOID AS $$
BEGIN
EXECUTE 'CREATE TABLE /* IF NOT EXISTS add for PostgreSQL 9.1+ */ sch.foo (
id serial NOT NULL,
demo_column varchar NOT NULL,
demo_column2 varchar NOT NULL,
CONSTRAINT pk_sch_foo PRIMARY KEY (id));
CREATE INDEX /* IF NOT EXISTS add for PostgreSQL 9.5+ */ idx_sch_foo_demo_column ON sch.foo(demo_column);
CREATE INDEX /* IF NOT EXISTS add for PostgreSQL 9.5+ */ idx_sch_foo_demo_column2 ON sch.foo(demo_column2);'
WHERE NOT EXISTS(SELECT * FROM information_schema.tables
WHERE table_schema = 'sch'
AND table_name = 'foo');
EXCEPTION WHEN null_value_not_allowed THEN
WHEN duplicate_table THEN
WHEN others THEN RAISE EXCEPTION '% %', SQLSTATE, SQLERRM;
END; $$ LANGUAGE plpgsql;
If you're trying to do interpolation for microtemplating, I like Mustache.js for that purpose.
sudo apt install libssl-dev
works on ubuntu 18.04.
the solution is simple if you importing
import org.junit.Test;
you have to run as junit 4
right click ->run as->Test config-> test runner-> as junit 4
For example this will start XBMC:
adb shell am start -a android.intent.action.MAIN -n org.xbmc.xbmc/android.app.NativeActivity
(More general answers are already posted, but I missed a nice example here.)
Easy — just use Font Awesome 5's default fa-[size]x
classes. You can scale icons up to 10x of the parent element's font-size
Read the docs about icon sizing.
Examples:
<span class="fas fa-info-circle fa-6x"></span>
<span class="fas fa-info-circle fa-7x"></span>
<span class="fas fa-info-circle fa-8x"></span>
<span class="fas fa-info-circle fa-9x"></span>
<span class="fas fa-info-circle fa-10x"></span>
ES6 / ES2015 provides an API for asking whether a string ends with something, which enables writing a cleaner and more readable function.
const stripTrailingSlash = (str) => {
return str.endsWith('/') ?
str.slice(0, -1) :
str;
};
Just for the record, there is a new HTTP Response Header called Clear-Site-Data
. If your server reply includes a Clear-Site-Data: "cookies"
header, then the authentication credentials (not only cookies) should be removed. I tested it on Chrome 77 but this warning shows on the console:
Clear-Site-Data header on 'https://localhost:9443/clear': Cleared data types:
"cookies". Clearing channel IDs and HTTP authentication cache is currently not
supported, as it breaks active network connections.
And the auth credentials aren't removed, so this doesn't works (for now) to implement basic auth logouts, but maybe in the future will. Didn't test on other browsers.

Simply write autofocus in the textfield. This is simple and it works like this:
<input name="abc" autofocus></input>
Hope this helps.
Important:
Make sure you're using System.Windows.Media.Brush
and not System.Drawing.Brush
They're not compatible and you'll get binding errors.
The color enumeration you need to use is also different
System.Windows.Media.Colors.Aquamarine (class name isColors
) <--- use this one System.Drawing.Color.Aquamarine (class name isColor
)
If in doubt use Snoop
and inspect the element's background property to look for binding errors - or just look in your debug log.
from the FAQ
elem = $("#elemid");
if (elem.is (".class")) {
// whatever
}
or:
elem = $("#elemid");
if (elem.hasClass ("class")) {
// whatever
}
Your interior <div>
elements should likely both be float:left
. Divs size to 100% the size of their container width automatically. Try using display:inline-block
instead of width:auto
on the container div. Or possibly float:left
the container and also apply overflow:auto
. Depends on what you're after exactly.
use the ternary operator ?:
change this
<?php if ($requestVars->_name == '') echo $redText; ?>
with
<?php echo ($requestVars->_name == '') ? $redText : ''; ?>
In short
// (Condition)?(thing's to do if condition true):(thing's to do if condition false);
In Android you can create shared buffer between C++ and Java (with directAlloc method) and manipulate it in both sides.
The GNU libc will print out information to /dev/tty
regarding some fatal conditions before it calls abort()
(which then triggers SIGABRT
), but if you are running your program as a service or otherwise not in a real terminal window, these message can get lost, because there is no tty to display the messages.
See my post on redirecting libc to write to stderr instead of /dev/tty:
One can also make use of the tracemalloc
module from the Python standard library. It seems to work well for objects whose class is implemented in C (unlike Pympler, for instance).
Her is another R base
approach:
From your example: Some date:
Some_date<-"01/01/1979"
We tell R, "That is a Date"
Some_date<-as.Date(Some_date)
We extract the month:
months(Some_date)
output: [1] "January"
Finally, we can convert it to a numerical variable:
as.numeric(as.factor(months(Some_date)))
outpt: [1] 1
You could use absolute positioning to pin the footer to the base of the parent div. I have also added 10px padding-bottom to the wrap (match the height of the footer). The absolute positioning is relative to the parent div rather than outside of the flow since you have already given it the position relative attribute.
body{ height:20000px }
#wrapper {padding:10%;}
#wrap{
float: left;
padding-bottom: 10px;
position: relative;
width: 40%;
background:#ccc;
}
#fixed{
position:absolute;
width:100%;
left: 0;
bottom: 0;
padding:0px;
height:10px;
background-color:#333;
}
Make sure your database myAttribute field contains null instead of zero.
Some cookies, such as referrer urls, have =
in them. As a result, simply splitting on =
will cause irregular results, and the previous answers here will breakdown over time (or immediately depending on your depth of use).
This takes only the first instance of the equals sign. It returns an object with the cookie's key value pairs.
// Returns an object of key value pairs for this page's cookies
function getPageCookies(){
// cookie is a string containing a semicolon-separated list, this split puts it into an array
var cookieArr = document.cookie.split(";");
// This object will hold all of the key value pairs
var cookieObj = {};
// Iterate the array of flat cookies to get their key value pair
for(var i = 0; i < cookieArr.length; i++){
// Remove the standardized whitespace
var cookieSeg = cookieArr[i].trim();
// Index of the split between key and value
var firstEq = cookieSeg.indexOf("=");
// Assignments
var name = cookieSeg.substr(0,firstEq);
var value = cookieSeg.substr(firstEq+1);
cookieObj[name] = value;
}
return cookieObj;
}
Use of the netstat -a
command will give you a list of connections to your system/server where you are executing the command.
For example it will display as below, where 35070 is the port number
TCP 10.144.0.159:**52121** sd-s-fgh:35070 ESTABLISHED
you have to add parameter also @zip
SqlConnection conn = new SqlConnection("Data Source=;Initial Catalog=;Persist Security Info=True;User ID=;Password=");
conn.Open();
SqlCommand command = new SqlCommand("Select id from [table1] where name=@zip", conn);
//
// Add new SqlParameter to the command.
//
command.Parameters.AddWithValue("@zip","india");
int result = (Int32) (command.ExecuteScalar());
using (SqlDataReader reader = command.ExecuteReader())
{
// iterate your results here
Console.WriteLine(String.Format("{0}",reader["id"]));
}
conn.Close();
You can access variables to any class without creating objects, if its extended by Application. They can be called globally and their state is maintained till application is not killed.
I use new Date().getTime()
, which will avoid collisions unless you have multiple requests happening within the same millisecond:
$.get('/getdata?_=' + new Date().getTime(), function(data) {
console.log(data);
});
Edit: This answer is several years old. It still works (hence I haven't deleted it), but there are better/cleaner ways of achieving this now. My preference is for this method, but this answer is also useful if you want to disable caching for every request during the lifetime of a page.
@nickf's correct. However, to be a little more precise:
// if you try to print it, it will return something like:
// Sat Mar 21 2009 20:13:07 GMT-0400 (Eastern Daylight Time)
// This time comes from the user's machine.
var myDate = new Date();
So if you want to display it as mm/dd/yyyy, you would do this:
var displayDate = (myDate.getMonth()+1) + '/' + (myDate.getDate()) + '/' + myDate.getFullYear();
Check out the full reference of the Date object. Unfortunately it is not nearly as nice to print out various formats as it is with other server-side languages. For this reason there-are-many-functions available in the wild.
You can use a simple regex like this:
public static string StripHTML(string input)
{
return Regex.Replace(input, "<.*?>", String.Empty);
}
Be aware that this solution has its own flaw. See Remove HTML tags in String for more information (especially the comments of @mehaase)
Another solution would be to use the HTML Agility Pack.
You can find an example using the library here: HTML agility pack - removing unwanted tags without removing content?
You can also try this:
Python 2.x:
python -c "import sys; print '\n'.join(sys.path)"
Python 3.x:
python3 -c "import sys; print('\n'.join(sys.path))"
The output will be more readable and clean, like so:
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload /Library/Python/2.7/site-packages /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC
Another way to compare two dates, is through the toISOString()
method. This is especially useful when comparing to a fixed date kept in a string, since you can avoid creating a short-lived object. By virtue of the ISO 8601 format, you can compare these strings lexicographically (at least when you're using the same timezone).
I'm not necessarily saying that it's better than using time objects or timestamps; just offering this as another option. There might be edge cases when this could fail, but I haven't stumbled upon them yet :)
Write the root logger as below for logging on both console and FILE
log4j.rootLogger=ERROR,console,FILE
And write the respective definitions like Target, Layout, and ConversionPattern (MaxFileSize for file etc).
Reimeus is right, you see this because of in.close in your chooseCave(). Also, this is wrong.
if (playAgain == "yes") {
play = true;
}
You should use equals instead of "==".
if (playAgain.equals("yes")) {
play = true;
}
I'd like to propose
np.min(np.append(np.where(aa>5)[0],np.inf))
This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where
returns an empty array).
You can do this in your code:
final ListView lv = (ListView) convertView.findViewById(R.id.list_view);
for (int i = 0; i < lv.getChildCount(); i++) {
((TextView)lv.getChildAt(i)).setTextColor(getResources().getColor(R.color.black));
}
No solution worked for me until I've checked and set app Tests target to same provisioning profile as main app. Or if you are using automatic singing make sure you have same team selected in Tests target.
For assemblies not in GAC, and which are referred in the build, sometimes this error also happens if the platform target does not match. So match the assembly platform type to the one where it is being used.
You could just write a little script that would try to import all the modules and tell you which ones are failing and which ones are working:
import pip
if __name__ == '__main__':
for package in pip.get_installed_distributions():
pack_string = str(package).split(" ")[0]
try:
if __import__(pack_string.lower()):
print(pack_string + " loaded successfully")
except Exception as e:
print(pack_string + " failed with error code: {}".format(e))
Output:
zope.interface loaded successfully
zope.deprecation loaded successfully
yarg loaded successfully
xlrd loaded successfully
WMI loaded successfully
Werkzeug loaded successfully
WebOb loaded successfully
virtualenv loaded successfully
...
Word of warning this will try to import everything so you'll see things like PyYAML failed with error code: No module named pyyaml
because the actual import name is just yaml. So as long as you know your imports this should do the trick for you.
To kill a process by a specific keyword you could create an alias in ~/.bashrc
(linux) or ~/.bash_profile
(mac).
alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"
Something like this should work: From Frans Bouma's Blog
SELECT * FROM
(
SELECT a.*, rownum r__
FROM
(
SELECT * FROM ORDERS WHERE CustomerID LIKE 'A%'
ORDER BY OrderDate DESC, ShippingDate DESC
) a
WHERE rownum < ((pageNumber * pageSize) + 1 )
)
WHERE r__ >= (((pageNumber-1) * pageSize) + 1)
rand() returns the next (pseudo) random number in a series. What's happening is you have the same series each time its run (default '1'). To seed a new series, you have to call srand() before you start calling rand().
If you want something random every time, you might try:
srand (time (0));
I just wanted to answer something new for this question - J2V8
.
Author Ian Bull says "Rhino and Nashorn are two common JavaScript runtimes, but these did not meet our requirements in a number of areas:
Neither support ‘Primitives‘. All interactions with these platforms require wrapper classes such as Integer, Double or Boolean. Nashorn is not supported on Android. Rhino compiler optimizations are not supported on Android. Neither engines support remote debugging on Android.""
As Mikkel posted before Collections.rotate is a simple way. I'm using this method for moving items up- and downward in a List.
public static <T> void moveItem(int sourceIndex, int targetIndex, List<T> list) {
if (sourceIndex <= targetIndex) {
Collections.rotate(list.subList(sourceIndex, targetIndex + 1), -1);
} else {
Collections.rotate(list.subList(targetIndex, sourceIndex + 1), 1);
}
}
This is because your <h1>
is the width of the centercol. Specify a width on the <h1>
and use margin: 0 auto;
if you want it centered.
Or, alternatively, you could float the <h1>
, which would make it only exactly as wide as the text.
As of June 2020, adding role='button'
to any HTML tag would add cursor: "pointer"

The DATEADD() function adds or subtracts a specified time interval from a date.
DATEADD(datepart,number,date)
datepart(interval) can be hour, second, day, year, quarter, week etc; number (increment int); date(expression smalldatetime)
For example if you want to add 30 days to current date you can use something like this
select dateadd(dd, 30, getdate())
To Substract 30 days from current date
select dateadd(dd, -30, getdate())
Class with private constructor is static.
Declare your class like this:
public class eOAuth {
private eOAuth(){}
public final static int ECodeOauthInvalidGrant = 0x1;
public final static int ECodeOauthUnknown = 0x10;
public static GetSomeStuff(){}
}
and you can used without initialization:
if (value == eOAuth.ECodeOauthInvalidGrant)
eOAuth.GetSomeStuff();
...
Use this:
<a href="<?php echo(($_SERVER['HTTPS'] ? 'https://' : 'http://').$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]); ?>">Whatever</a>
It will create a HREF using the current URL...
Octave is basically an open source version of MATLAB. It was written to be just that. MATLAB has a very nice GUI which makes it a bit easier to use but the next stable release of OCTAVE will also have a GUI, which I have tested in the unstable release, and looks fantastic. Octave is much more buggy because it was developed and maintained by a group of volunteers, where the development of MATLAB is funded by millions of dollars by industry. I'm still a student and am using a student version of MATLAB, but I am thinking of going over to Octave once the stable version with the GUI is released.
MATLAB is probably a lot more powerful than Octave, and the algorithms run faster, but for most applications, Octave is more than adequate and is, in my opinion' an amazing tool that is completely free, where Octave is completely free.
I would say use MATLAB while you can use the academic version, but the switch to Octave should be seamless as they use the exact same syntax.
Lastly, there is the issue of SIMULINK. If you want to do simulation or control system design (there are probably a million other uses) SIMULINK is fantastic and comes with MATLAB. I don't think any other comes close to this, although Scilab is apparently a 'good' open source alternative, I haven't tried it.
Peace.
Running the following command
composer remove Vendor/Package Name
That's all. No need composer update. Vendor/Package Name is just directory as installed before
cron
is dangerous. If one instance of cron fails to finish before the next is due, they are likely to fight each other.
It would be better to have a continuously running job that would delete some rows, sleep some, then repeat.
Also, INDEX(datetime)
is very important for avoiding deadlocks.
But, if the datetime test includes more than, say, 20% of the table, the DELETE
will do a table scan. Smaller chunks deleted more often is a workaround.
Another reason for going with smaller chunks is to lock fewer rows.
Bottom line:
INDEX(datetime)
Other deletion techniques: http://mysql.rjweb.org/doc.php/deletebig

You have to less secure the security of the mail sender. if the problem persist I think It can be caused by the antivirus, try to disable it ..
The documentation here encourages listening to the onbeforeunload event and/or adding an event listener on window.
window.addEventListener('beforeunload', function(event) {
//do something here
}, false);
You can also just populate the .onunload or .onbeforeunload properties of window with a function or a function reference.
Though behaviour is not standardized across browsers, the function may return a value that the browser will display when confirming whether to leave the page.
what about this:
# get difference between dates `"01.12.2013"` and `"31.12.2013"`
# weeks
difftime(strptime("26.03.2014", format = "%d.%m.%Y"),
strptime("14.01.2013", format = "%d.%m.%Y"),units="weeks")
Time difference of 62.28571 weeks
# months
(as.yearmon(strptime("26.03.2014", format = "%d.%m.%Y"))-

I got tired of waiting for this to get built into SVN. I was using tortoiseSVN with ignore-on-commit, but that pops up a user dialog box that you can't suppress from the command line, and when I run my build script and go and make a cup of tea, I hate it when I come back to discover it's waiting for user input 10% of the way through.
So here's a windows powershell script that commits only files that aren't in a changelist:
# get list of changed files into targets
[XML]$svnStatus = svn st -q --xml C:\SourceCode\Monad
# select the nodes that aren't in a changelist
$fileList = $svnStatus.SelectNodes('/status/target/entry[wc-status/@item != "unversioned"]') | Foreach-Object {$_.path};
# create a temp file of targets
$fileListPath = [IO.Path]::GetTempFileName();
$fileList | out-file $fileListPath -Encoding ASCII
# do the commit
svn commit --targets $fileListPath -m "Publish $version" --keep-changelists
# remove the temp file
Remove-Item $filelistPath
There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).
With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.
On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.
Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.
P.D.: my father worked at graphic arts, this is why i know this... :-P

IUSR is part of IIS_IUSER group.so i guess you can remove the permissions for IUSR without worrying. Further Reading
However, a problem arose over time as more and more Windows system services started to run as NETWORKSERVICE. This is because services running as NETWORKSERVICE can tamper with other services that run under the same identity. Because IIS worker processes run third-party code by default (Classic ASP, ASP.NET, PHP code), it was time to isolate IIS worker processes from other Windows system services and run IIS worker processes under unique identities. The Windows operating system provides a feature called "Virtual Accounts" that allows IIS to create unique identities for each of its Application Pools. DefaultAppPool is the by default pool that is assigned to all Application Pool you create.
To make it more secure you can change the IIS DefaultAppPool Identity to ApplicationPoolIdentity.
Regarding permission, Create and Delete summarizes all the rights that can be given. So whatever you have assigned to the IIS_USERS group is that they will require. Nothing more, nothing less.
hope this helps.
Intellisense does work for C# 6, and it's great.
For running console apps you should set up some additional tools:
&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}
npm
.yo
: npm install -g yo grunt-cli generator-aspnet bower
c:\Users\Username\.dnx\bin\dnvm.cmd upgrade -u
Then you can use yo
as wizard for Console Application: yo aspnet
Choose name and project type. After that go to created folder cd ./MyNewConsoleApp/
and run dnu restore
To execute your program just type >run
in Command Palette (Ctrl+Shift+P
), or execute dnx . run
in shell from the directory of your project.
For completeness and simplicity sake, the following should be fine:

It does the job quite well in my case, but others seem to have issues with whitespace. In that case, the answer from ucefkh
provides a workaround from a comment in the PHP manual.
Looks like the path you gave doesn't have any bootstrap files in them.
href="~/lib/bootstrap/dist/css/bootstrap.min.css"
Make sure the files exist over there , else point the files to the correct path, which should be in your case
href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"
If it were me, I would avoid any risky revision editing and do the following instead:
Create a new branch on the SHA where 222 was committed, basically as a bookmark.
Switch back to the main branch. In it, revert commit 222.
Push all the commits that have been made, which will push commit 111 only, because 222 was reverted.
Work on the branch from step #1 if needed. Merge from the trunk to it as needed to keep it up to date. I wouldn't bother with stash.
When it's time for the changes in commit 222 to go in, that branch can be merged to trunk.
It seems that it doesn't turn it into a string. Try
row.HeaderCell.Value = String.Format("{0}", row.Index + 1);
If we consider common scenarios where this exception can be thrown, accessing properties withing object at the top.
Ex:
string postalcode=Customer.Address.PostalCode;
//if customer or address is null , this will through exeption
in here , if address is null , then you will get NullReferenceException.
So, as a practice we should always use null check, before accessing properties in such objects (specially in generic)
string postalcode=Customer?.Address?.PostalCode;
//if customer or address is null , this will return null, without through a exception
For nested dictionary/JSON lookups, you can use dictor
pip install dictor
dict object
{
"characters": {
"Lonestar": {
"id": 55923,
"role": "renegade",
"items": [
"space winnebago",
"leather jacket"
]
},
"Barfolomew": {
"id": 55924,
"role": "mawg",
"items": [
"peanut butter jar",
"waggy tail"
]
},
"Dark Helmet": {
"id": 99999,
"role": "Good is dumb",
"items": [
"Shwartz",
"helmet"
]
},
"Skroob": {
"id": 12345,
"role": "Spaceballs CEO",
"items": [
"luggage"
]
}
}
}
to get Lonestar's items, simply provide a dot-separated path, ie
import json
from dictor import dictor
with open('test.json') as data:
data = json.load(data)
print dictor(data, 'characters.Lonestar.items')
>> [u'space winnebago', u'leather jacket']
you can provide fallback value in case the key isnt in path
theres tons more options you can do, like ignore letter casing and using other characters besides '.' as a path separator,
Add
export PATH=$PATH:/home/me/play

In order to link the issue number to your commit message, you should add:
#issue_number
in your git commit message.
Example Commit Message from Udacity Git Commit Message Style Guide
feat: Summarize changes in around 50 characters or less
More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of the commit and the rest of the text as the body. The
blank line separating the summary from the body is critical (unless
you omit the body entirely); various tools like `log`, `shortlog`
and `rebase` can get confused if you run the two together.
Explain the problem that this commit is solving. Focus on why you
are making this change as opposed to how (the code explains that).
Are there side effects or other unintuitive consequenses of this
change? Here's the place to explain them.
Further paragraphs come after blank lines.
- Bullet points are okay, too
- Typically a hyphen or asterisk is used for the bullet, preceded
by a single space, with blank lines in between, but conventions
vary here
If you use an issue tracker, put references to them at the bottom,
like this:

it depends on your need, u can use either this.renderIcon()
or bind this.renderIcon.bind(this)

This is how you call a method outside the render.
buttonClick(){
console.log("came here")
}
render() {
return (
<div className="patient-container">
<button onClick={this.buttonClick.bind(this)}>Click me</button>

The recommended way is to write a separate component and import it.
and how do I then make the warning go away?
You are probably going to have to reinstall or upgrade your NuGet packages to fix this.
Was looking at how to trust a certificate while using jenkins cli, and found https://issues.jenkins-ci.org/browse/JENKINS-12629 which has some recipe for that.
This will give you the certificate:
openssl s_client -connect ${HOST}:${PORT} </dev/null
if you are interested only in the certificate part, cut it out by piping it to:
| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'
and redirect to a file:
> ${HOST}.cert
Then import it using keytool:
keytool -import -noprompt -trustcacerts -alias ${HOST} -file ${HOST}.cert \
-keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}
In one go:
HOST=myhost.example.com
PORT=443
KEYSTOREFILE=dest_keystore
KEYSTOREPASS=changeme
# get the SSL certificate
openssl s_client -connect ${HOST}:${PORT} </dev/null \
| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert
# create a keystore and import certificate
keytool -import -noprompt -trustcacerts \
-alias ${HOST} -file ${HOST}.cert \
-keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}
# verify we've got it.
keytool -list -v -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS} -alias ${HOST}
There is a much simpler solution for that.
Actually treating the items of JArray
as JObject
works.
Here is an example:
Let's say we have such array of JSON objects:
JArray jArray = JArray.Parse(@"[
{
""name"": ""Croke Park II"",
""url"": ""http://twitter.com/search?q=%22Croke+Park+II%22"",
""promoted_content"": null,
""query"": ""%22Croke+Park+II%22"",
""events"": null
},
{
""name"": ""Siptu"",
""url"": ""http://twitter.com/search?q=Siptu"",
""promoted_content"": null,
""query"": ""Siptu"",
""events"": null
}]");
To get access each item we just do the following:
foreach (JObject item in jArray)
{
string name = item.GetValue("name").ToString();
string url = item.GetValue("url").ToString();
// ...
}
In this particular case, due to the dangers cited in other answers, I would
Edit in e.g. Vim and :%s/\s/\\\0/g
, escaping all space characters with a backslash.
Then :%s/^/rm -rf /
, prepending the command. With -r
you don't have to worry to have directories listed after the files contained therein, and with -f
it won't complain due to missing files or duplicate entries.
Run all the commands: $ source 1.txt
You want to loop on the .Rows, and access the column for the row like q("column")
Just:
For Each q In dtDataTable.Rows
strDetail = q("Detail")

I know this is a old thread but I've just had to do this. While the other approaches here work, I wanted an easy way to be able to affect a lot of calls to string.format
. So adding the Math.Truncate
to all the calls to wasn't really a good option. Also as some of the formatting is stored in a database, it made it even worse.
Thus, I made a custom format provider which would allow me to add truncation to the formatting string, eg:
string.format(new FormatProvider(), "{0:T}", 1.1299); // 1.12
string.format(new FormatProvider(), "{0:T(3)", 1.12399); // 1.123
string.format(new FormatProvider(), "{0:T(1)0,000.0", 1000.9999); // 1,000.9
The implementation is pretty simple and is easily extendible to other requirements.
public class FormatProvider : IFormatProvider, ICustomFormatter
{
public object GetFormat(Type formatType)
{
if (formatType == typeof (ICustomFormatter))
{
return this;
}
return null;
}
public string Format(string format, object arg, IFormatProvider formatProvider)
{
if (arg == null || arg.GetType() != typeof (double))
{
try
{
return HandleOtherFormats(format, arg);
}
catch (FormatException e)
{
throw new FormatException(string.Format("The format of '{0}' is invalid.", format));
}
}
if (format.StartsWith("T"))
{
int dp = 2;
int idx = 1;
if (format.Length > 1)
{
if (format[1] == '(')
{
int closeIdx = format.IndexOf(')');
if (closeIdx > 0)
{
if (int.TryParse(format.Substring(2, closeIdx - 2), out dp))
{
idx = closeIdx + 1;
}
}
else
{
throw new FormatException(string.Format("The format of '{0}' is invalid.", format));
}
}
}
double mult = Math.Pow(10, dp);
arg = Math.Truncate((double)arg * mult) / mult;
format = format.Substring(idx);
}
try
{
return HandleOtherFormats(format, arg);
}
catch (FormatException e)
{
throw new FormatException(string.Format("The format of '{0}' is invalid.", format));
}
}
private string HandleOtherFormats(string format, object arg)
{
if (arg is IFormattable)
{
return ((IFormattable) arg).ToString(format, CultureInfo.CurrentCulture);
}
return arg != null ? arg.ToString() : String.Empty;
}
}
You can use file redirection to redirected the sorted output:
sort input-file > output_file
Or you can use the -o
, --output=FILE
option of sort to indicate the same input and output file:
sort -o file file
Without repeating the filename (with bash brace expansion)
sort -o file{,}
?? Note: A common mistake is to try to redirect the output to the same input file
(e.g. sort file > file
). This does not work as the shell is making the redirections (not the sort(1) program) and the input file (as being the output also) will be erased just before giving the sort(1) program the opportunity of reading it.
You can convert .jar file to .exe on these ways:
(source: viralpatel.net)
1- JSmooth .exe wrapper:
JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a web site.
JSmooth provides a variety of wrappers for your java application, each of them having their own behaviour: Choose your flavour!
Download: http://jsmooth.sourceforge.net/
2- JarToExe 1.8
Jar2Exe is a tool to convert jar files into exe files.
Following are the main features as describe in their website:
Download: http://www.brothersoft.com/jartoexe-75019.html
3- Executor
Package your Java application as a jar, and Executor will turn the jar into a Windows exe file, indistinguishable from a native application. Simply double-clicking the exe file will invoke the Java Runtime Environment and launch your application.
Download: http://mpowers.net/executor/
EDIT: The above link is broken, but here is the page (with working download) from the Internet Archive. http://web.archive.org/web/20090316092154/http://mpowers.net/executor/
4- Advanced Installer
Advanced Installer lets you create Windows MSI installs in minutes. This also has Windows Vista support and also helps to create MSI packages in other languages.
Download: http://www.advancedinstaller.com/
Let me know other tools that you have used to convert JAR to EXE.
The accepted solution here is incorrect. Try this in the HTML:
onchange="setTwoNumberDecimal(this)"
and the function to look like:
function setTwoNumberDecimal(el) {
el.value = parseFloat(el.value).toFixed(2);
};
I also found useful to run this:
./gradlew dI --dependency <your library>
This shows how are being dependencies resolved (dependencyInsight
) and help you debugging into where do you need to force or exclude libraries in your build.gradle
See: https://docs.gradle.org/current/userguide/tutorial_gradle_command_line.html

The main purpose of the interfaces is that it makes a contract between you and any other class that implement that interface which makes your code decoupled and allows expandability.
Along with Java 14, it starts supporting Record. You may want to check that https://docs.oracle.com/en/java/javase/14/docs/api/java.base/java/lang/Record.html
public record Person (String name, String address) {}
Person person = new Person("Esteban", "Stormhaven, Tamriel");
And there are Sealed Classes after Java 15. https://openjdk.java.net/jeps/360
sealed interface Shape permits Circle, Rectangle {
record Circle(Point center, int radius) implements Shape { }
record Rectangle(Point lowerLeft, Point upperRight) implements Shape { }
}

For the original question based on Bootstrap 3, the solution was to use push-pull.
In Bootstrap 4 it's now possible to change the order, even when the columns are full-width stacked vertically, thanks to Bootstrap 4 flexbox. OFC, the push pull method will still work, but now there are other ways to change column order in Bootstrap 4, making it possible to re-order full-width columns.
Method 1 - Use flex-column-reverse
for xs
screens:
<div class="row flex-column-reverse flex-md-row">
<div class="col-md-3">
sidebar
</div>
<div class="col-md-9">
main
</div>
</div>
Method 2 - Use order-first
for xs
screens:
<div class="row">
<div class="col-md-3">
sidebar
</div>
<div class="col-md-9 order-first order-md-last">
main
</div>
</div>
Bootstrap 4(alpha 6): http://www.codeply.com/go/bBMOsvtJhD
Bootstrap 4.1: https://www.codeply.com/go/e0v77yGtcr
Original 3.x Answer
For the original question based on Bootstrap 3, the solution was to use push-pull for the larger widths, and then the columns will show is their natural order on smaller (xs) widths. (A-B reverse to B-A).
<div class="container">
<div class="row">
<div class="col-md-9 col-md-push-3">
main
</div>
<div class="col-md-3 col-md-pull-9">
sidebar
</div>
</div>
</div>
Bootstrap 3: http://www.codeply.com/go/wgzJXs3gel
@emre stated, "You cannot change the order of columns in smaller screens but you can do that in large screens". However, this should be clarified to state: "You cannot change the order of full-width "stacked" columns.." in Bootstrap 3.

If it does not solve your problem then check whether your XML files are not open by another thread using these configuration files.. and provide some more details if still persists.
Loop in reverse by decrementing i
to avoid the problem:
for (var i = arrayOfObjects.length - 1; i >= 0; i--) {
var obj = arrayOfObjects[i];
if (listToDelete.indexOf(obj.id) !== -1) {
arrayOfObjects.splice(i, 1);
}
}
Or use filter
:
var newArray = arrayOfObjects.filter(function(obj) {
return listToDelete.indexOf(obj.id) === -1;
});
Most of the solutions presented here would crash for large values and should not be used in production code.
If you don't care for very large values use this code to clamp the Double
to max/min Int
values.
let bigFloat = Float.greatestFiniteMagnitude
let smallFloat = -bigFloat
extension Float {
func toIntTruncated() -> Int {
let maxTruncated = min(self, Float(Int.max).nextDown)
let bothTruncated = max(maxTruncated, Float(Int.min))
return Int(bothTruncated)
}
}
// This crashes:
// let bigInt = Int(bigFloat)
// this works for values up to 9223371487098961920
let bigInt = bigFloat.toIntTruncated()
let smallInt = smallFloat.toIntTruncated()
According to the article Chris Corio: Teach Your Apps To Play Nicely With Windows Vista User Account Control, MSDN Magazine, Jan. 2007, only ShellExecute
checks the embedded manifest and prompts the user for elevation if needed, while CreateProcess
and other APIs don't. Hope it helps.

You can do that without an I/O redirection:
sed -i 's/$/\n/' filename
You can also use this command to append a newline to a list of files:
find dir -name filepattern | xargs sed -i 's/$/\n/' filename
For echo
, some shells implement it as a shell builtin command. It might not accept the -e
option. If you still want to use echo
, try to find where the echo
binary file is, using which echo
. In most cases, it is located in /bin/echo
, so you can use /bin/echo -e "\n"
to echo a new line.
Basically this error comes when npm server is not started.
So at first check the npm server status, if it's not running then start npm with command npm start
and you can see in terminal:
Loading dependency graph done.
Now npm is started and run your app in another terminal with command
react-native run-android
Is it possible that you can avoid using wsdl2java? You can straight away use CXF FrontEnd APIs to invoke your SOAP Webservice. The only catch is that you need to create your SEI and VOs on your client end. Here is a sample code.
package com.aranin.weblog4j.client;
import com.aranin.weblog4j.services.BookShelfService;
import com.aranin.weblog4j.vo.BookVO;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class DemoClient {
public static void main(String[] args){
String serviceUrl = "http://localhost:8080/weblog4jdemo/bookshelfservice";
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(BookShelfService.class);
factory.setAddress(serviceUrl);
BookShelfService bookService = (BookShelfService) factory.create();
//insert book
BookVO bookVO = new BookVO();
bookVO.setAuthor("Issac Asimov");
bookVO.setBookName("Foundation and Earth");
String result = bookService.insertBook(bookVO);
System.out.println("result : " + result);
bookVO = new BookVO();
bookVO.setAuthor("Issac Asimov");
bookVO.setBookName("Foundation and Empire");
result = bookService.insertBook(bookVO);
System.out.println("result : " + result);
bookVO = new BookVO();
bookVO.setAuthor("Arthur C Clarke");
bookVO.setBookName("Rama Revealed");
result = bookService.insertBook(bookVO);
System.out.println("result : " + result);
//retrieve book
bookVO = bookService.getBook("Foundation and Earth");
System.out.println("book name : " + bookVO.getBookName());
System.out.println("book author : " + bookVO.getAuthor());
}
}

The account which is running the service might not have mapped the D:-drive (they are user-specific). Try sharing the directory, and use full UNC-path in your backupConfig
.
Your watcher
of type FileSystemWatcher
is a local variable, and is out of scope when the OnStart
method is done. You probably need it as an instance or class variable.
I've used encodeURIComponent() and decodeURIComponent() too.
If You have Legacy Cordova framework having issues with NPM and Cordova command. I would suggest the below option.
Create file android/res/xml/network_security_config.xml -
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">Your URL(ex: 127.0.0.1)</domain>
</domain-config>
</network-security-config>
AndroidManifest.xml -
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:networkSecurityConfig="@xml/network_security_config"
...>
...
</application>
</manifest>
Use initial default values for all parameters like below
public string GetFindBooks(string author="", string title="", string isbn="", string somethingelse="", DateTime? date= null)
{
// ...
}
I'm not expert enough in the inner workings of Postgres to know why your query with the double condition in the WHERE
clause be not working. But one way to get around this would be to use a UNION
of the two queries which you know do work:
SELECT * FROM table_name WHERE boolean_column IS NULL
UNION
SELECT * FROM table_name WHERE boolean_column = FALSE
You could also try using COALESCE
:
SELECT * FROM table_name WHERE COALESCE(boolean_column, FALSE) = FALSE
This second query will replace all NULL
values with FALSE
and then compare against FALSE
in the WHERE
condition.
Same problem occurred with me while creating a view. The view was present earlier then due to some changes it got removed But when I tried to add it again it was showing me "view already exists" error message.
Solution:
You can do one thing manually.
It will create the table successfully.
Java implicitly assumes a reference to the current object for methods called like this. So
// Test2.java
public class Test2 {
public void testMethod() {
testMethod2();
}
// ...
}
Is exactly the same as
// Test2.java
public class Test2 {
public void testMethod() {
this.testMethod2();
}
// ...
}
I prefer the second version to make more clear what you want to do.
If you're really lucky, like I was, you can go back into your text editor and hit 'undo'.
I know that's not really a proper answer, but it saved me half a day's work so hopefully it'll do the same for someone else!
The exception android.view.InflateException: Binary XML file line: #... Error inflating class fragment
might happen if you manipulate with getActivity()
inside your fragment before onActivityCreated()
get called. In such case you receive a wrong activity reference and can't rely on that.
For instance the next pattern is wrong:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
final View view = inflater.inflate(R.layout..., container, false);
Button button = getActivity().findViewById(R.id...);
button.setOnClickListener(...); - another problem: button is null
return view;
}
Correct pattern #1
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
final View view = inflater.inflate(R.layout..., container, false);
Button button = view.findViewById(R.id...);
button.setOnClickListener(...);
return view;
}
Correct pattern #2
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Button button = getActivity().findViewById(R.id...);
button.setOnClickListener(...);
}
As often stated before, you should not use regular expressions to process XML or HTML documents. They do not perform very well with HTML and XML documents, because there is no way to express nested structures in a general way.
You could use the following.
String result = Regex.Replace(htmlDocument, @"<[^>]*>", String.Empty);
This will work for most cases, but there will be cases (for example CDATA containing angle brackets) where this will not work as expected.
It May be due to some exceptions like (Parsing NUMERIC to String or vise versa).
Please verify cell values either are null or do handle Exception and see.
