Maybe node.js has changed, but it seems there are some problems with the other solutions (using node v8.1.2):
file.close()
in the finish
event. Per default the fs.createWriteStream
is set to autoClose: https://nodejs.org/api/fs.html#fs_fs_createwritestream_path_optionsfile.close()
should be called on error. Maybe this is not needed when the file is deleted (unlink()
), but normally it is: https://nodejs.org/api/stream.html#stream_readable_pipe_destination_optionsstatusCode !== 200
fs.unlink()
without a callback is deprecated (outputs warning)dest
file exists; it is overriddenBelow is a modified solution (using ES6 and promises) which handles these problems.
const http = require("http");
const fs = require("fs");
function download(url, dest) {
return new Promise((resolve, reject) => {
const file = fs.createWriteStream(dest, { flags: "wx" });
const request = http.get(url, response => {
if (response.statusCode === 200) {
response.pipe(file);
} else {
file.close();
fs.unlink(dest, () => {}); // Delete temp file
reject(`Server responded with ${response.statusCode}: ${response.statusMessage}`);
}
});
request.on("error", err => {
file.close();
fs.unlink(dest, () => {}); // Delete temp file
reject(err.message);
});
file.on("finish", () => {
resolve();
});
file.on("error", err => {
file.close();
if (err.code === "EEXIST") {
reject("File already exists");
} else {
fs.unlink(dest, () => {}); // Delete temp file
reject(err.message);
}
});
});
}
In the cell you want your result to appear, use the following formula:
=COUNTIF(A1:A200,"<>")
That will count all cells which have a value and ignore all empty cells in the range of A1 to A200.

In Notepad++ you don't need to use Regular Expressions for this.
Hold down alt to allow you to select a rectangle of text across multiple rows at once. Select the chunk you want to be rid of, and press delete.
Most people recommend using notifyDataSetChanged()
, but I found this link pretty useful. In fact using clear
and add
you can accomplish the same goal using less memory footprint, and more responsibe app.
For example:
notesListAdapter.clear();
notes = new ArrayList<Note>();
notesListAdapter.add(todayNote);
if (birthdayNote != null) notesListAdapter.add(birthdayNote);
/* no need to refresh, let the adaptor do its job */
Your script syntax is valid bash and good.
Possible causes for the failure:
Your bash
is not really bash but ksh
or some other shell which doesn't understand bash's parameter substitution. Because your script looks fine and works with bash.
Do ls -l /bin/bash
and check it's really bash and not sym-linked to some other shell.
If you do have bash on your system, then you may be executing your script the wrong way like: ksh script.sh
or sh script.sh
(and your default shell is not bash). Since you have proper shebang, if you have bash ./script.sh
or bash ./script.sh
should be fine.
If we have 3 parameters (t0, a0, a1)
for Relu, that is we want to implement
if x > t0:
x = x * a1
else:
x = x * a0
We can use the following code:
X = X * (X > t0) * a1 + X * (X < t0) * a0
X
there is a matrix.
Just use it as you would a non-concurrent collection. The Concurrent[Collection] classes wrap the regular collections so that you don't have to think about synchronizing access.
Edit: ConcurrentLinkedList isn't actually just a wrapper, but rather a better concurrent implementation. Either way, you don't have to worry about synchronization.
Updating state every second in the react class. Note the my index.js passes a function that return current time.
import React from "react";
class App extends React.Component {
constructor(props){
super(props)
this.state = {
time: this.props.time,
}
}
updateMe() {
setInterval(()=>{this.setState({time:this.state.time})},1000)
}
render(){
return (
<div className="container">
<h1>{this.state.time()}</h1>
<button onClick={() => this.updateMe()}>Get Time</button>
</div>
);
}
}
export default App;
The difference between MyString[0]
and MyString.ToCharArray()[0]
is that the former treats the string as a read-only array, while ToCharArray()
creates a new array. The former will be quicker (along with easier) for almost anything where it will work, but ToCharArray
can be necessary if you have a method that needs to accept an array, or if you want to change the array.
If the string isn't known to be non-null and non-empty you could do:
string.IsNullOrEmpty(MyString) ? (char?)null : MyString[0]
which returns a char?
of either null or the first character in the string, as appropriate.
I'm assuming what you want to do is run a command without an interface (possibly automatically?). On windows there are a number of options for what you are looking for:
Best: write your program as a windows service. These will start when no one logs into the server. They let you select the user account (which can be different than your own) and they will restart if they fail. These run all the time so you can automate tasks at specific times or on a regular schedule from within them. For more information on how to write a windows service you can read a tutorial online such as (http://msdn.microsoft.com/en-us/library/zt39148a(v=vs.110).aspx).
Better: Start the command and hide the window. Assuming the command is a DOS command you can use a VB or C# script for this. See here for more information. An example is:
Set objShell = WScript.CreateObject("WScript.Shell")
objShell.Run("C:\yourbatch.bat"), 0, True
You are still going to have to start the command manually or write a task to start the command. This is one of the biggest down falls of this strategy.
Hope that helps some!
That error is a parse error. The parser is throwing it while going through the code, trying to understand it. No code is being executed yet in the parsing stage. Because of that it hasn't yet executed the error_reporting
line, therefore the error reporting settings aren't changed yet.
You cannot change error reporting settings (or really, do anything) in a file with syntax errors.
The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!
If you want to hide them anyway: error_reporting(0);
WebRTC is designed for high-performance, high quality communication of video, audio and arbitrary data. In other words, for apps exactly like what you describe.
WebRTC apps need a service via which they can exchange network and media metadata, a process known as signaling. However, once signaling has taken place, video/audio/data is streamed directly between clients, avoiding the performance cost of streaming via an intermediary server.
WebSocket on the other hand is designed for bi-directional communication between client and server. It is possible to stream audio and video over WebSocket (see here for example), but the technology and APIs are not inherently designed for efficient, robust streaming in the way that WebRTC is.
As other replies have said, WebSocket can be used for signaling.
I maintain a list of WebRTC resources: strongly recommend you start by looking at the 2013 Google I/O presentation about WebRTC.
Even if it is a little bit late, i solved the PATH problem by removing every space.
;C:\Program Files\PostgreSQL\9.5\bin;C:\Program Files\PostgreSQL\9.5\lib
works for me now.
That's not exactly what I had in mind. What do you do if you have a generic type to only be known at runtime?
public MyDTO toObject() {
try {
var methodInfo = MethodBase.GetCurrentMethod();
if (methodInfo.DeclaringType != null) {
var fullName = methodInfo.DeclaringType.FullName + "." + this.dtoName;
Type type = Type.GetType(fullName);
if (type != null) {
var obj = JsonConvert.DeserializeObject(payload);
//var obj = JsonConvert.DeserializeObject<type.MemberType.GetType()>(payload); // <--- type ?????
...
}
}
// Example for java.. Convert this to C#
return JSONUtil.fromJSON(payload, Class.forName(dtoName, false, getClass().getClassLoader()));
} catch (Exception ex) {
throw new ReflectInsightException(MethodBase.GetCurrentMethod().Name, ex);
}
}
In your case all you need to do is to find object in array and use Array.prototype.splice()
method, read more details here:
var arr = [{id: 1, name: "Person 1"}, {id:2, name:"Person 2"}];_x000D_
_x000D_
// Find item index using _.findIndex (thanks @AJ Richardson for comment)_x000D_
var index = _.findIndex(arr, {id: 1});_x000D_
_x000D_
// Replace item at index using native splice_x000D_
arr.splice(index, 1, {id: 100, name: 'New object.'});_x000D_
_x000D_
// "console.log" result_x000D_
document.write(JSON.stringify( arr ));
_x000D_
<script src="//cdnjs.cloudflare.com/ajax/libs/lodash.js/2.4.1/lodash.min.js"></script>
_x000D_
You could also do something like this :
const str = "hi, there"_x000D_
_x000D_
const res = str.includes("hello") || str.includes("hi") || str.includes('howdy');_x000D_
_x000D_
console.log(res);
_x000D_
Whenever one of your includes return true, value will be true, otherwise, it's going to be false. This works perfectly fine with ES6.
Just a recommendation:
I'd recommend using the DOM table implementation, it's very straight forward and easy to use, you really don't need jQuery for this task.
var table = document.getElementById('tblOne');
var rowLength = table.rows.length;
for(var i=0; i<rowLength; i+=1){
var row = table.rows[i];
//your code goes here, looping over every row.
//cells are accessed as easy
var cellLength = row.cells.length;
for(var y=0; y<cellLength; y+=1){
var cell = row.cells[y];
//do something with every cell here
}
}
- What does the ENABLE_BITCODE actually do, will it be a non-optional requirement in the future?
I'm not sure at what level you are looking for an answer at, so let's take a little trip. Some of this you may already know.
When you build your project, Xcode invokes clang
for Objective-C targets and swift
/swiftc
for Swift targets. Both of these compilers compile the app to an intermediate representation (IR), one of these IRs is bitcode. From this IR, a program called LLVM takes over and creates the binaries needed for x86 32 and 64 bit modes (for the simulator) and arm6/arm7/arm7s/arm64 (for the device). Normally, all of these different binaries are lumped together in a single file called a fat binary.
The ENABLE_BITCODE option cuts out this final step. It creates a version of the app with an IR bitcode binary. This has a number of nice features, but one giant drawback: it can't run anywhere. In order to get an app with a bitcode binary to run, the bitcode needs to be recompiled (maybe assembled or transcoded… I'm not sure of the correct verb) into an x86 or ARM binary.
When a bitcode app is submitted to the App Store, Apple will do this final step and create the finished binaries.
Right now, bitcode apps are optional, but history has shown Apple turns optional things into requirements (like 64 bit support). This usually takes a few years, so third party developers (like Parse) have time to update.
- can I use the above method without any negative impact and without compromising a future appstore submission?
Yes, you can turn off ENABLE_BITCODE and everything will work just like before. Until Apple makes bitcode apps a requirement for the App Store, you will be fine.
- Are there any performance impacts if I enable / disable it?
There will never be negative performance impacts for enabling it, but internal distribution of an app for testing may get more complicated.
As for positive impacts… well that's complicated.
For distribution in the App Store, Apple will create separate versions of your app for each machine architecture (arm6/arm7/arm7s/arm64) instead of one app with a fat binary. This means the app installed on iOS devices will be smaller.
In addition, when bitcode is recompiled (maybe assembled or transcoded… again, I'm not sure of the correct verb), it is optimized. LLVM is always working on creating new a better optimizations. In theory, the App Store could recreate the separate version of the app in the App Store with each new release of LLVM, so your app could be re-optimized with the latest LLVM technology.
Use the command dir
to list all the directories and files in a directory; ls
is a unix command.
VB6 Installs just fine on Windows 7 (and Windows 8 / Windows 10) with a few caveats.
Here is how to install it:
C:\Windows
called MSJAVA.DLL
. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero-byte file, the installation of moldy Java is bypassed, and no reboot will be required.SETUP.EXE
, select Run As Administrator
.C:\Program Files\Microsoft Visual Studio\VB98\
After changing these settings, fire up the IDE, and things should be back to normal, and the IDE is no longer sluggish.

DTO
is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.
DTO
should only contain private fields for your data, getters, setters, and constructors.DTO
is not recommended to add business logic methods to such classes, but it is OK to add some util methods.DAO
is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).
Here is an example of how the DAO and DTO interfaces would look like:
interface PersonDTO {
String getName();
void setName(String name);
//.....
}
interface PersonDAO {
PersonDTO findById(long id);
void save(PersonDTO person);
//.....
}
The MVC
is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.
As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

Here are some examples which assume $element
is a jQuery
element:
// Element width including overflow (scrollbar)
$element[0].offsetWidth; // 1280 in your case
// Element width excluding overflow (scrollbar)
$element[0].clientWidth; // 1280 - scrollbarWidth
// Scrollbar width
$element[0].offsetWidth - $element[0].clientWidth; // 0 if no scrollbar
1. show collections; // Display all collections
2. show tables // Display all collections
3. db.getCollectionNames(); // Return array of collection. Example :[ "orders", "system.profile" ]
Detailed information for every collection:
db.runCommand( { listCollections: 1.0, authorizedCollections: true, nameOnly: true } )
To list collections list based on a search string.
db.getCollectionNames().filter(function (CollectionName) { return /<Search String>/.test(CollectionName) })
Example: Find all collection having "import" in the name
db.getCollectionNames().filter(function (CollectionName) { return /import/.test(CollectionName) })
Just use the following command
git show a2c25061

{
Console.WriteLine(val);

You can user pagination of Instagram PHP API: https://github.com/cosenary/Instagram-PHP-API/wiki/Using-Pagination
Something like that:
$Instagram = new MetzWeb\Instagram\Instagram(array(
"apiKey" => IG_APP_KEY,
"apiSecret" => IG_APP_SECRET,
"apiCallback" => IG_APP_CALLBACK
));
$Instagram->setSignedHeader(true);
$pictures = $Instagram->getUserMedia(123);
do {
foreach ($pictures->data as $picture_data):
echo '<img src="'.$picture_data->images->low_resolution->url.'">';
endforeach;
} while ($pictures = $instagram->pagination($pictures));
VLookup
You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".
External Reference
To reference a cell of the same Workbook use the following pattern:
<Sheetname>!<Cell>
Example:
Table1!A1
To reference a cell of a different Workbook use this pattern:
[<Workbook_name>]<Sheetname>!<Cell>
Example:
[MyWorkbook]Table1!A1
This is the best method i think so.
$base_url = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != "off") ? "https" : "http");
$base_url .= "://".$_SERVER['HTTP_HOST'];
$base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
echo $base_url;
a = [0,1,2,3,127,200,255]
print str.join("", ("%02x" % i for i in a))
prints

(Also note that your code will fail for integers in the range from 10 to 15.)
You are just missing the first argument to connect
, which is the mapStateToProps
method. Excerpt from the Redux todo app:
const mapStateToProps = (state) => {
return {
todos: getVisibleTodos(state.todos, state.visibilityFilter)
}
}
const mapDispatchToProps = (dispatch) => {
return {
onTodoClick: (id) => {
dispatch(toggleTodo(id))
}
}
}
const VisibleTodoList = connect(
mapStateToProps,
mapDispatchToProps
)(TodoList)
Here's some code that works for us. We found MSIE to be hit and miss with DomContentLoaded
, there appears to be some delay when no additional resources are cached (up to 300ms based on our console logging), and it triggers too fast when they are cached. So we resorted to a fallback for MISE. You also want to trigger the doStuff()
function whether DomContentLoaded
triggers before or after your external JS files.
// detect MSIE 9,10,11, but not Edge
ua=navigator.userAgent.toLowerCase();isIE=/msie/.test(ua);
function doStuff(){
//
}
if(isIE){
// play it safe, very few users, exec ur JS when all resources are loaded
window.onload=function(){doStuff();}
} else {
// add event listener to trigger your function when DOMContentLoaded
if(document.readyState==='loading'){
document.addEventListener('DOMContentLoaded',doStuff);
} else {
// DOMContentLoaded already loaded, so better trigger your function
doStuff();
}
}
Follow up to accepted answer.
You need something other than CTRL-D to designate the end if using this in a script. Try this instead:
cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF
This will append text to the stated file (not including "EOF").
It utilizes a here document (or heredoc).
However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.
This variation will work when you are typing directly on the command line:
sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'
Or you can use tee
instead to avoid the command line sudo issue seen when using the heredoc with cat:
tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF
Use That :
$(selector).trigger("change");
OR
$('#id').trigger("click");
OR
$('.class').trigger(event);
Trigger can be any event that javascript support.. Hope it's easy to understandable to all of You.
This means that you must declare strict mode by writing "use strict"
at the beginning of the file or the function to use block-scope declarations.
EX:
function test(){
"use strict";
let a = 1;
}
The method you used (AddWithValue
) doesn't convert null
values to database nulls. You should use DBNull.Value
instead:
myCommand.Parameters.AddWithValue(
"@SurgeryDate",
someDate == null ? DBNull.Value : (object)someDate
);
This will pass the someDate
value if it is not null
, or DBNull.Value
otherwise. In this case correct value will be passed to the database.
When you use 'getResource' on a Class, a relative path is resolved based on the package the Class is in. When you use 'getResource' on a ClassLoader, a relative path is resolved based on the root folder.
If you use an absolute path, both 'getResource' methods will start at the root folder.

To restore your Homebrew setup try this:
cd /usr/local/Homebrew/Library && git stash && git clean -d -f && git reset --hard && git pull
It is called closure.
Basically, the function defined within other function is accessible only within this function. But may be passed as a result and then this result may be called.
It is a very powerful feature. You can see more explanation here:
For Swift 5 just the same as Swift 4
let button = UIButton()
button.frame = CGRect(x: self.view.frame.size.width - 60, y: 60, width: 50, height: 50)
button.backgroundColor = UIColor.red
button.setTitle("Name your Button ", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
@objc func buttonAction(sender: UIButton!) {
print("Button tapped")
}
If you are clearing the cluster so that you can start again, then, in addition to what @rib47 said, I also do the following to ensure my systems are in a state ready for kubeadm init
again:
kubeadm reset -f
rm -rf /etc/cni /etc/kubernetes /var/lib/dockershim /var/lib/etcd /var/lib/kubelet /var/run/kubernetes ~/.kube/*
iptables -F && iptables -X
iptables -t nat -F && iptables -t nat -X
iptables -t raw -F && iptables -t raw -X
iptables -t mangle -F && iptables -t mangle -X
systemctl restart docker
You then need to re-install docker.io
, kubeadm
, kubectl
, and kubelet
to make sure they are at the latest versions for your distribution before you re-initialize the cluster.
EDIT: Discovered that calico adds firewall rules to the raw
table so that needs clearing out as well.
If you need your certificate for HTTPS connections you can add the .bks file as a raw resource to your application and extend DefaultHttpConnection so your certificates are used for HTTPS connections.

I think that's up to you to show that dialog for choosing. For Gallery you'll use that code, and for Camera try this.
OPTION 1: Add this line to ~/.zshrc:
export "PATH=$HOME/pear/bin:$PATH"
After that you need to run source ~/.zshrc
in order your changes to take affect OR close this window and open a new one
OPTION 2: execute it inside the terminal console to add this path only to the current terminal window session. When you close the window/session, it will be lost.
Because the operating system may not do so. The flush operation forces the file data into the file cache in RAM, and from there it's the OS's job to actually send it to the disk.
You're trying to insert $newdate
into your db. You need to convert it to a string first. Use the DateTime::format
method to convert back to a string.
It works for me in all the browsers:
document.onkeydown = function(){
switch (event.keyCode){
case 116 : //F5 button
event.returnValue = false;
event.keyCode = 0;
return false;
case 82 : //R button
if (event.ctrlKey){
event.returnValue = false;
event.keyCode = 0;
return false;
}
}
}
The (A==B).all()
solution is very neat, but there are some built-in functions for this task. Namely array_equal
, allclose
and array_equiv
.
(Although, some quick testing with timeit
seems to indicate that the (A==B).all()
method is the fastest, which is a little peculiar, given it has to allocate a whole new array.)

Other than that, I'm not sure how much more concise you can get, without maybe writing your own specialized "First" and "FirstOrDefault" extension methods.

I just wanted to add this answer specifically for Mac Users.
My server was running perfectly fine until I updated my xcode. The while starting my rails server the error was shown like this
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

And there was suggestion to install mysql2 gem at the end of the error message. So when i tried installing it I got the error as above mentioned in this question. The error I got is as follows
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
So as suggested in this post I tried 'brew install mysql' and that quitted saying that mysql version so and so already installed. But there was warning before it saying
Warning: You have not agreed to the Xcode license.
Builds will fail! Agree to the license by opening Xcode.app or running:
xcodebuild -license
Then I tried this sudo xcodebuild -license
and type 'agree' at the end. You have to be root to agree to the license.
After this, I again tried bundle install and then everything is working fine as normal. [ Even due to this xcode updation, I had problem with my tower also.]
lazy-init is the attribute of bean. The values of lazy-init can be true and false. If lazy-init is true, then that bean will be initialized when a request is made to bean. This bean will not be initialized when the spring container is initialized and if lazy-init is false then the bean will be initialized with the spring container initialization.
A user agent style sheet is a ”default style sheet” provided by the browser (e.g., Chrome, Firefox, Edge, etc.) in order to present the page in a way that satisfies ”general presentation expectations.” For example, a default style sheet would provide base styles for things like font size, borders, and spacing between elements. It is common to employ a reset style sheet to deal with inconsistencies amongst browsers.
From the specification...
A user agent's default style sheet should present the elements of the document language in ways that satisfy general presentation expectations for the document language. ~ The Cascade.
For more information about user agents in general, see user agent.
We faced the same problem:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error error opening file /fs01/app/rms01/external/logs/SH_EXT_TAB_VGAG_DELIV_SCHED.log
In our case we had a RAC with 2 nodes. After giving write permission on the log directory, on both sides, everything worked fine.
There can be another way which saves the day. Just init a new Dialog with desired layout and just show it. I need it for showing a loadingView over a DialogFragment and this was the only way I succeed.
Dialog topDialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
topDialog.setContentView(R.layout.dialog_top);
topDialog.show();
bringToFront() might not work in some cases like mine. But content of dialog_top layout must override anything on the ui layer. But anyway, this is an ugly workaround.
If using Sql Server Management Studio Designer just select both rows (Shift+Click) and Set Primary Key.
Nice clean solution:

fpassthru($fp);
fclose($fp);

The above code snippets is easy method to get values from the user.
use JSON.stringify(userData)
to coverty json object to string.
var dataStore = $.cookie("basket-data", JSON.stringify($("#ArticlesHolder").data()));
and for getting back from cookie use JSON.parse()
var data=JSON.parse($.cookie("basket-data"))
This is super old, but hopefully this helps somebody. I'm sending responses with different error codes back and this is the only solution I've found that works in
$.ajax({
data: {
"data": "mydata"
},
type: "POST",
url: "myurl"
}).done(function(data){
alert(data);
}).fail(function(data){
alert(data.responseText)
});
Since JQuery deprecated the success
and error
functions, it's you need to use done
and fail
, and access the data with data.responseText
when in fail
, and just with data
when in done
. This is similar to @Marco Pavan 's answer, but you don't need any JQuery plugins or anything to use it.
You can drop the range(len())
:
weights_h = [[random.random() for e in inputs[0]] for e in range(hiden_neurons)]
But really, you should probably use numpy.
In [9]: numpy.random.random((3, 3))
Out[9]:
array([[ 0.37052381, 0.03463207, 0.10669077],
[ 0.05862909, 0.8515325 , 0.79809676],
[ 0.43203632, 0.54633635, 0.09076408]])
My preferred method is not to do that at all. The age of constants pretty much died when Java 5 introduced typesafe enums. And even before then Josh Bloch published a (slightly more wordy) version of that, which worked on Java 1.4 (and earlier).
Unless you need interoperability with some legacy code there's really no reason to use named String/integer constants anymore.
I had to add blank lines after a table and I manage it adding many divs as I need it with a css style with padding-top set it up, like this. I've used a template engine (underscore) to loop through the number of lines I need to add.
<% var maxRow = 30; var pos = items.models.length; %>
<% for( pos; pos < maxRow; pos++ ){ %>
<div class="blankRow"></div>
<% }; %>
My css file:
.blankRow:{ padding-top: 15px;}
Create a button with an id share and add the following code snippet.
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "Your body here";
String shareSub = "Your subject here";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, shareSub);
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share using"));
}
});
The above code snippet will open the share chooser on share button click action. However, note...The share code snippet might not output very good results using emulator. For actual results, run the code snippet on android device to get the real results.
SELECT COLUMN_NAME 'all_columns'

You should loop by rows and then columns with a structure like
for ...row index...
for ...column index...
print
but I guess this is homework so just try it out yourself.
Swap the row/column index in the for loops depending on if you need to go across first and then down, vs. down first and then across.
If you have hosted your website already it advisable to use the email or create an offical mail to send the email Let say your url is www.example.com.

Then change your smtp which will be mail.example.com. The ssl will remain 465
Presuming every new branch in your tree is a div, I have implemented this solution with 2 functions:
function fillArray(vector1,vector2){
for (var i = 0; i < vector1.length; i++){
if (vector1[i].id.indexOf('q17_') == 0)
vector2.push(vector1[i]);
if(vector1[i].tagName == 'DIV')
fillArray (document.getElementById(vector1[i].id).children,vector2);
}
}
function selectAllElementsInsideDiv(divId){
var matches = new Array();
var searchEles = document.getElementById(divId).children;
fillArray(searchEles,matches);
return matches;
}
Now presuming your div's id is 'myDiv', all you have to do is create an array element and set its value to the function's return:
var ElementsInsideMyDiv = new Array();
ElementsInsideMyDiv = selectAllElementsInsideDiv('myDiv')
I have tested it and it worked for me. I hope it helps you.
Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this
String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");
and now you have a String which can be parsed back to java.lang.Number
, for example,
long veryLongNumber = Long.parseLong(intStr);
Or you can use the java 8 streams, if you hate regex,
String strOfInts = Arrays
.stream(intArray)
.mapToObj(String::valueOf)
.reduce((a, b) -> a.concat(",").concat(b))
.get();
If you are looking to render JSON as HTML and it can be collapsed/opened, you can use this directive that I just made to render it nicely:
In the situation where you are NOT going to use this over and over (i.e. not needed in your style sheet), inline style statements usually work anywhere they would work inyour style sheet. E.g:
<div data-role="controlgroup" data-type="horizontal" style="text-align:center;">
try it like this
StringBuilder sb = new StringBuilder();
foreach (ListItem item in ddlAge.Items)
{
if (item.Selected)
{
string sqlCommand = "SELECT * from TableA WHERE Age IN (@Age)";
SqlConnection sqlCon = new SqlConnection(connectString);
SqlCommand sqlComm = new SqlCommand();
sqlComm.Connection = sqlCon;
sqlComm.CommandType = System.Data.CommandType.Text;
sqlComm.CommandText = sqlCommand;
sqlComm.CommandTimeout = 300;
sqlComm.Parameters.Add("@Age", SqlDbType.NVarChar);
sb.Append(item.Text + ",");
sqlComm.Parameters["@Age"].Value = sb.ToString().TrimEnd(',');
}
}

This is an example that works out of the box. If you want less "hacky", you should use inheritance library or such.
Well in a file animal.js you would write:
var method = Animal.prototype;
function Animal(age) {
this._age = age;
}
method.getAge = function() {
return this._age;
};
module.exports = Animal;
To use it in other file:
var Animal = require("./animal.js");
var john = new Animal(3);
If you want a "sub class" then inside mouse.js:
var _super = require("./animal.js").prototype,
method = Mouse.prototype = Object.create( _super );
method.constructor = Mouse;
function Mouse() {
_super.constructor.apply( this, arguments );
}
//Pointless override to show super calls
//note that for performance (e.g. inlining the below is impossible)
//you should do
//method.$getAge = _super.getAge;
//and then use this.$getAge() instead of super()
method.getAge = function() {
return _super.getAge.call(this);
};
module.exports = Mouse;
Also you can consider "Method borrowing" instead of vertical inheritance. You don't need to inherit from a "class" to use its method on your class. For instance:
var method = List.prototype;
function List() {
}
method.add = Array.prototype.push;
...
var a = new List();
a.add(3);
console.log(a[0]) //3;
I think this will be much simpler for beginners in JavaScript
//The function checks if the password and confirm password match
// Then disables the submit button for mismatch but enables if they match
function checkPass()
{
//Store the password field objects into variables ...
var pass1 = document.getElementById("register-password");
var pass2 = document.getElementById("confirm-password");
//Store the Confimation Message Object ...
var message = document.getElementById('confirmMessage');
//Set the colors we will be using ...
var goodColor = "#66cc66";
var badColor = "#ff6666";
//Compare the values in the password field
//and the confirmation field
if(pass1.value == pass2.value){
//The passwords match.
//Set the color to the good color and inform
//the user that they have entered the correct password
pass2.style.backgroundColor = goodColor;
message.style.color = goodColor;
message.innerHTML = "Passwords Match!"
//Enables the submit button when there's no mismatch
var tabPom = document.getElementById("btnSignUp");
$(tabPom ).prop('disabled', false);
}else{
//The passwords do not match.
//Set the color to the bad color and
//notify the user.
pass2.style.backgroundColor = badColor;
message.style.color = badColor;
message.innerHTML = "Passwords Do Not Match!"
//Disables the submit button when there's mismatch
var tabPom = document.getElementById("btnSignUp");
$(tabPom ).prop('disabled', true);
}
}
If you want to search on both FROM and TO airports, you'll want to join on the Airports table twice - then you can use both from and to tables in your results set:

Airports fromAirports on Flights.fairport = fromAirports.code
INNER JOIN

So my question is: Is there a way to tell the compiler that a long long int is the also a int64_t, just like long int is?
This is a good question or problem, but I suspect the answer is NO.
Also, a long int
may not be a long long int
.
# if __WORDSIZE == 64 typedef long int int64_t; # else __extension__ typedef long long int int64_t; # endif
I believe this is libc. I suspect you want to go deeper.
In both 32-bit compile with GCC (and with 32- and 64-bit MSVC), the output of the program will be:
int: 0 int64_t: 1 long int: 0 long long int: 1
32-bit Linux uses the ILP32 data model. Integers, longs and pointers are 32-bit. The 64-bit type is a long long
.
Microsoft documents the ranges at Data Type Ranges. The say the long long
is equivalent to __int64
.
However, the program resulting from a 64-bit GCC compile will output:
int: 0 int64_t: 1 long int: 1 long long int: 0
64-bit Linux uses the LP64
data model. Longs are 64-bit and long long
are 64-bit. As with 32-bit, Microsoft documents the ranges at Data Type Ranges and long long is still __int64
.
There's a ILP64
data model where everything is 64-bit. You have to do some extra work to get a definition for your word32
type. Also see papers like 64-Bit Programming Models: Why LP64?
But this is horribly hackish and does not scale well (actual functions of substance, uint64_t, etc)...
Yeah, it gets even better. GCC mixes and matches declarations that are supposed to take 64 bit types, so its easy to get into trouble even though you follow a particular data model. For example, the following causes a compile error and tells you to use -fpermissive
:
#if __LP64__
typedef unsigned long word64;
#else
typedef unsigned long long word64;
#endif
// intel definition of rdrand64_step (http://software.intel.com/en-us/node/523864)
// extern int _rdrand64_step(unsigned __int64 *random_val);
// Try it:
word64 val;
int res = rdrand64_step(&val);
It results in:
error: invalid conversion from `word64* {aka long unsigned int*}' to `long long unsigned int*'
So, ignore LP64
and change it to:
typedef unsigned long long word64;
Then, wander over to a 64-bit ARM IoT gadget that defines LP64
and use NEON:
error: invalid conversion from `word64* {aka long long unsigned int*}' to `uint64_t*'
It is true that a java class can implement multiple interfaces at the same time, but there is a catch here. If in a class, you are trying to implement two java interfaces, which contains methods with same signature but diffrent return type, in that case you will get compilation error.
interface One
{
int m1();
}
interface Two
{
float m1();
}
public class MyClass implements One, Two{
int m1() {}
float m1() {}
public static void main(String... args) {
}
}
output :
prog.java:14: error: method m1() is already defined in class MyClass
public float m1() {}

prog.java:11: error: MyClass is not abstract and does not override abstract method m1() in Two
public class MyClass implements One, Two{

You can use the re
module for regexes, but regexes are probably overkill for what you want. I might try something like
z.write(article[:article.index("</html>") + 7]
This is much cleaner, and should be much faster than a regex based solution.
If someone using gulp, it show an error if we use document.getElementById()

context.Entry(entry).CurrentValues.SetValues(entity);
}

}
This was in an async method, but I've forgot to put await before GetEntryAsync, and so I got this same error...
To avoid handling exceptions use a regular expression to make sure you have all digits first:
//Checking for Regular expression that matches digits
if(value.matches("\\d+")) {
Integer.parseInt(value);
}

The difference with look-arounds and just regular groups are that with regular groups the comma would be part of the match, and with look-arounds it wouldn't. In this case it doesn't make a difference though.
Using the release version of MVC, here is what I do:

I obviously have some application specific stuff in here regarding the path construction, but the returning of the FileStreamResult is nice and simple.
I did some performance testing in regards to this action against your everyday call to the image (bypassing the controller) and the difference between the averages was only about 3 milliseconds (controller avg was 68ms, non-controller was 65ms).
I had tried some of the other methods mentioned in answers here and the performance hit was much more dramatic... several of the solutions responses were as much as 6x the non-controller (other controllers avg 340ms, non-controller 65ms).

I had the same problem with three projects in one solution and all of the suggestions didn't work until I made a reference in the reference file of the web site project to the project where the edmx file sits.
You could use something like a set from Programming in Lua:
function Set (list)
local set = {}
for _, l in ipairs(list) do set[l] = true end
return set
end
Then you could put your list in the Set and test for membership:
local items = Set { "apple", "orange", "pear", "banana" }
if items["orange"] then
-- do something
end
Or you could iterate over the list directly:
local items = { "apple", "orange", "pear", "banana" }
for _,v in pairs(items) do
if v == "orange" then
-- do something
break
end
end
Open up your file using regular old vanilla Notepad that comes with Windows.
It will show you the encoding of the file when you click "Save As...".
It'll look like this:
Whatever the default-selected encoding is, that is what your current encoding is for the file.
If it is UTF-8, you can change it to ANSI and click save to change the encoding (or visa-versa).
I realize there are many different types of encoding, but this was all I needed when I was informed our export files were in UTF-8 and they required ANSI. It was a onetime export, so Notepad fit the bill for me.
FYI: From my understanding I think "Unicode" (as listed in Notepad) is a misnomer for UTF-16.
More here on Notepad's "Unicode" option: Windows 7 - UTF-8 and Unicdoe

As of May 2017, multiple FROM
s can be used in a single Dockerfile.
See "Builder pattern vs. Multi-stage builds in Docker" (by Alex Ellis) and PR 31257 by Tõnis Tiigi.
The general syntax involves adding
FROM
additional times within your Dockerfile - whichever is the lastFROM
statement is the final base image. To copy artifacts and outputs from intermediate images useCOPY --from=<base_image_number>
.
FROM golang:1.7.3 as builder

RUN apk --no-cache add ca-certificates

what is a base image?
A set of files, plus EXPOSE
'd ports, ENTRYPOINT
and CMD
.
You can add files and build a new image based on that base image, with a new Dockerfile
starting with a FROM
directive: the image mentioned after FROM
is "the base image" for your new image.
does it mean that if I declare
neo4j/neo4j
in aFROM
directive, that when my image is run the neo database will automatically run and be available within the container on port 7474?
Only if you don't overwrite CMD
and ENTRYPOINT
.
But the image in itself is enough: you would use a FROM neo4j/neo4j
if you had to add files related to neo4j
for your particular usage of neo4j
.
You can also set background is transparent. So the button looks like fit your icon.

Instead of if-else condition use if in both conditions. it will work that way but not sure why.
Update 2:
Xcode 9 appears to have a "feature" where it will ignore the file's current line endings, and instead just use your default line-ending setting when inserting lines into a file, resulting in files with mixed line endings.
I'm pretty sure this bug didn't exist in Xcode 7; not sure about Xcode 8. The good news is that it appears to be fixed in Xcode 10.
For the time it existed, this bug caused a small amount of hilarity in the codebase I refer to in the question (which to this day uses autocrlf=false
), and led to many "EOL" commit messages and eventually to my writing a git pre-commit
hook to check for/prevent introducing mixed line endings.
Update:
Note: As noted by VonC, starting from Git 2.8, merge markers will not introduce Unix-style line-endings to a Windows-style file.
Original:
One little hiccup that I've noticed with this setup is that when there are merge conflicts, the lines git adds to mark up the differences do not have Windows line-endings, even when the rest of the file does, and you can end up with a file with mixed line endings, e.g.:
// Some code<CR><LF>
<<<<<<< Updated upstream<LF>
// Change A<CR><LF>
=======<LF>
// Change B<CR><LF>
>>>>>>> Stashed changes<LF>
// More code<CR><LF>
This doesn't cause us any problems (I imagine any tool that can handle both types of line-endings will also deal sensible with mixed line-endings--certainly all the ones we use do), but it's something to be aware of.
The other thing* we've found, is that when using git diff
to view changes to a file that has Windows line-endings, lines that have been added display their carriage returns, thus:
// Not changed
+ // New line added in^M
+^M
// Not changed
// Not changed
* It doesn't really merit the term: "issue".
What about this?
my_string = "123,456.908"
commas_removed = my_string.replace(',', '') # remove comma separation
my_float = float(commas_removed) # turn from string to float.
In short:
my_float = float(my_string.replace(',', ''))
It seems that 32809 is a general error message. After struggling for some time, I found that I had not clicked on the "Enable Macros" security button at the below the workbook ribbon. Once I did this, everything worked fine.
Please take care that the epoch time is in second and Date object accepts Long value which is in milliseconds. Hence you would have to multiply epoch value with 1000 to use it as long value . Like below :-
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
sdf.setTimeZone(TimeZone.getTimeZone(timeZone));
Long dateLong=Long.parseLong(sdf.format(epoch*1000));
To sort the array by the value of the "title" key use:
uasort($myArray, function($a, $b) {
return strcmp($a['title'], $b['title']);
});
strcmp compare the strings.
uasort() maintains the array keys as they were defined.
It's all in the tutorial how to do that:
ContentValues args = new ContentValues();
args.put(columnName, newValue);
db.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null);
Use ContentValues
to set the updated columns and than the update()
method in which you have to specifiy, the table and a criteria to only update the rows you want to update.
With method chaining:
product = (
df1.assign(key=1)
.merge(df2.assign(key=1), on="key")
.drop("key", axis=1)
)
Change the file name if your file name is like pandas.py or pd.py, it will shadow the real name otherwise.
This is what I did:
EF:
using (var context = new SomeDBContext())
{
foreach (var item in model.ShopItems) // ShopItems is a posted list with values
{
var feature = context.Shop
.Where(h => h.ShopID == 123 && h.Type == item.Type).ToList();
feature.ForEach(a => a.SortOrder = item.SortOrder);
}
context.SaveChanges();
}
Hope helps someone.
I found a simple way to auto-detect file encodings - change the file to a text file (on a mac rename the file extension to .txt) and drag it to a Mozilla Firefox window (or File -> Open). Firefox will detect the encoding - you can see what it came up with under View -> Character Encoding.
I changed my file's encoding using TextMate once I knew the correct encoding. File -> Reopen using encoding and choose your encoding. Then File -> Save As and change the encoding to UTF-8 and line endings to LF (or whatever you want)
This format works, but it doesn't seem to be an official way of doing so
http://maps.google.com/maps?q=loc:36.26577,-92.54324
Also you may want to take a look at this. They have a few answers and seem to indicate that this is the new method:
http://maps.google.com/maps?&z=10&q=36.26577+-92.54324&ll=36.26577+-92.54324
You can use valueOf("a1")
if you want to look up by String
from help (spec -h):
-l, --line LINE_NUMBER Execute example group or example at given line.
(does not work for dynamically generated examples)
Example: spec spec/runner_spec.rb -l 162
The problem is that the columns used in the ORDER BY
aren't specified in the DISTINCT
. To do this, you need to use an aggregate function to sort on, and use a GROUP BY
to make the DISTINCT
work.
Try something like this:
SELECT DISTINCT Category, MAX(CreationDate)
FROM MonitoringJob
GROUP BY Category
ORDER BY MAX(CreationDate) DESC, Category
You are missing the directive that states the connection uses SSL

"I swap each bytes right?" -> yes, to convert between little and big endian, you just give the bytes the opposite order. But at first realize few things:
uint32_t
is 32bits, which is 4 bytes, which is 8 HEX digits0xf
retrieves the 4 least significant bits, to retrieve 8 bits, you need 0xff
so in case you want to swap the order of 4 bytes with that kind of masks, you could:
uint32_t res = 0;
b0 = (num & 0xff) << 24; ; least significant to most significant
b1 = (num & 0xff00) << 8; ; 2nd least sig. to 2nd most sig.
b2 = (num & 0xff0000) >> 8; ; 2nd most sig. to 2nd least sig.
b3 = (num & 0xff000000) >> 24; ; most sig. to least sig.
res = b0 | b1 | b2 | b3 ;
I was working on some groovy code, which doesn't auto-format on save. What I did was right-click on the code pane, then chose ESLint Fix. That fixed my indents.
I had this happen when I was trying to use a deployment key because that is exactly what I wanted.
I could connect via ssh -T [email protected]
and it would tell me I had access to read the repository I wanted, but git clone
would fail.
Clearing out ~/.ssh/known_hosts
, generating a new key via ssh-keygen
, adding that new key to bitbucket, and retrying fixed it for me.
I found this version most suitable for all cases. It doesn't remove all whitespaces.
For example "a (test) b" -> "a b"
"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim();
"Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();
I recommend Google protocol buffers. I had the chance to test drive the library on a new project and it's remarkably easy to use. The library is heavily optimized for performance.
Protobuf is different than other serialization solutions mentioned here in the sense that it does not serialize your objects, but rather generates code for objects that are serialization according to your specification.
A generic solution with a timeout:
import time
def onerror_retry(exception, callback, timeout=2, timedelta=.1):
end_time = time.time() + timeout
while True:
try:
yield callback()
break
except exception:
if time.time() > end_time:
raise
elif timedelta > 0:
time.sleep(timedelta)
Usage:
for retry in onerror_retry(SomeSpecificException, do_stuff):
retry()
I need more information really but it will be along the lines of..
SELECT table1.*, table2.col1, table2.col3 FROM table1 JOIN table2 USING(id)
according the documentation, this should do it...
RESET QUERY CACHE
Only redirection won't work, since there's nothing to connect the now-open file descriptors. So no, there is no way like this.
You can get to the root from within each site using $_SERVER['DOCUMENT_ROOT']
. For testing ONLY you can echo out the path to make sure it's working, if you do it the right way. You NEVER want to show the local server paths for things like includes and requires.
Site 1
echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/';
Includes under site one would be at:
echo $_SERVER['DOCUMENT_ROOT'].'/includes/'; // should be '/main_web_folder/includes/';
Site 2
echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/blog/';
The actual code to access includes from site1 inside of site2 you would say:
include($_SERVER['DOCUMENT_ROOT'].'/../includes/file_from_site_1.php');
It will only use the relative path of the file executing the query if you try to access it by excluding the document root
and the root
slash:
//(not as fool-proof or non-platform specific)
include('../includes/file_from_site_1.php');
Included paths have no place in code on the front end (live) of the site anywhere, and should be secured and used in production environments only.
Additionally for URLs on the site itself you can make them relative to the domain. Browsers will automatically fill in the rest because they know which page they are looking at. So instead of:
<a href='http://www.__domain__name__here__.com/contact/'>Contact</a>
You should use:
<a href='/contact/'>Contact</a>
For good SEO you'll want to make sure that the URLs for the blog do not exist in the other domain, otherwise it may be marked as a duplicate site. With that being said you might also want to add a line to your robots.txt
file for ONLY site1:
User-agent: *
Disallow: /blog/
Look up your IP address and include this snippet of code:
function is_dev(){
//use the external IP from Google.
//If you're hosting locally it's 127.0.01 unless you've changed it.
$ip_address='xxx.xxx.xxx.xxx';
if ($_SERVER['REMOTE_ADDR']==$ip_address){
return true;
} else {
return false;
}
}
if(is_dev()){
echo $_SERVER['DOCUMENT_ROOT'];
}
Remember if your ISP changes your IP, as in you have a DCHP Dynamic IP, you'll need to change the IP in that file to see the results. I would put that file in an include, then require it on pages for debugging.
If you're okay with modern methods like using the browser console log you could do this instead and view it in the browser's debugging interface:
if(is_dev()){
echo "<script>".PHP_EOL;
echo "console.log('".$_SERVER['DOCUMENT_ROOT']."');".PHP_EOL;
echo "</script>".PHP_EOL;
}
Try this:
SELECT DATEDIFF(dd, 0,GETDATE()) + CONVERT(DATETIME,'03:30:00.000')
Use PUT for updating incomplete/partial resource.
You can accept jObject as parameter and parse its value to update the resource.
Below is the function which you can use as a reference :
public IHttpActionResult Put(int id, JObject partialObject)
{
Dictionary<string, string> dictionaryObject = new Dictionary<string, string>();
foreach (JProperty property in json.Properties())
{
dictionaryObject.Add(property.Name.ToString(), property.Value.ToString());
}
int id = Convert.ToInt32(dictionaryObject["id"]);
DateTime startTime = Convert.ToDateTime(orderInsert["AppointmentDateTime"]);
Boolean isGroup = Convert.ToBoolean(dictionaryObject["IsGroup"]);
//Call function to update resource
update(id, startTime, isGroup);
return Ok(appointmentModelList);
}
org.apache.commons.lang3.StringUtils:
public static String replaceIgnoreCase(String text, String searchString, String replacement)
Case insensitively replaces all occurrences of a String within another String.
Have a look at what happens if you run javaws.exe directly from the command line.
Any time you get the...
"Fatal error: Call to a member function bind_param() on boolean"
...it is likely because there is an issue with your query. The prepare()
might return FALSE
(a Boolean), but this generic failure message doesn't leave you much in the way of clues. How do you find out what is wrong with your query? You ask!
First of all, make sure error reporting is turned on and visible: add these two lines to the top of your file(s) right after your opening <?php
tag:
error_reporting(E_ALL);
ini_set('display_errors', 1);
If your error reporting has been set in the php.ini you won't have to worry about this. Just make sure you handle errors gracefully and never reveal the true cause of any issues to your users. Revealing the true cause to the public can be a gold engraved invitation for those wanting to harm your sites and servers. If you do not want to send errors to the browser you can always monitor your web server error logs. Log locations will vary from server to server e.g., on Ubuntu the error log is typically located at /var/log/apache2/error.log
. If you're examining error logs in a Linux environment you can use tail -f /path/to/log
in a console window to see errors as they occur in real-time....or as you make them.
Once you're squared away on standard error reporting adding error checking on your database connection and queries will give you much more detail about the problems going on. Have a look at this example where the column name is incorrect. First, the code which returns the generic fatal error message:
$sql = "SELECT `foo` FROM `weird_words` WHERE `definition` = ?";
$query = $mysqli->prepare($sql)); // assuming $mysqli is the connection
$query->bind_param('s', $definition);
$query->execute();
The error is generic and not very helpful to you in solving what is going on.
With a couple of more lines of code you can get very detailed information which you can use to solve the issue immediately. Check the prepare()
statement for truthiness and if it is good you can proceed on to binding and executing.
$sql = "SELECT `foo` FROM `weird_words` WHERE `definition` = ?";
if($query = $mysqli->prepare($sql)) { // assuming $mysqli is the connection
$query->bind_param('s', $definition);
$query->execute();
// any additional code you need would go here.
} else {
$error = $mysqli->errno . ' ' . $mysqli->error;
echo $error; // 1054 Unknown column 'foo' in 'field list'
}
If something is wrong you can spit out an error message which takes you directly to the issue. In this case there is no foo
column in the table, solving the problem is trivial.
If you choose, you can include this checking in a function or class and extend it by handling the errors gracefully as mentioned previously.
Auth was closest but his answer throws a type mismatch error.
As for the other answers you should avoid using an error to test for a condition, if you can, because at the very least it complicates debugging (what if something else is causing that error).
Here's a simple, complete solution:
option explicit
Function foo() As Variant
Dim bar() As String
If (Not Not bar) Then
ReDim Preserve bar(0 To UBound(bar) + 1)
Else
ReDim Preserve bar(0 To 0)
End If
bar(UBound(bar)) = "it works!"
foo = bar
End Function
The answer to your question is that you need to have permissions. Type the following code in your manifest.xml file:
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.WRITE_OWNER_DATA"></uses-permission>
<uses-permission android:name="android.permission.READ_OWNER_DATA"></uses-permission>`
It worked for me...
I had this same problem and resolved it by making sure all references to the previous version of crystal from the Web Config file, the server, and the publishing workstation were removed. Other than the full trust basically everything that user707217 did, I did and it worked for my upgraded Web application
You can certainly format the date yourself..
var mydate = new Date(form.startDate.value);
var month = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"][mydate.getMonth()];
var str = month + ' ' + mydate.getFullYear();
You can also use an external library, such as DateJS.
Here's a DateJS example:
<script src="http://www.datejs.com/build/date.js" type="text/javascript"></script>
<script>
var mydate = new Date(form.startDate.value);
var str = mydate.toString("MMMM yyyy");
window.alert(str);
</script>
You can use enumeration and a map, so your string will become the key and enum value is value for that key.
It is really easy to do a bulk insert in Laravel using Eloquent or the query builder.
You can use the following approach.
$data = [
['user_id'=>'Coder 1', 'subject_id'=> 4096],
['user_id'=>'Coder 2', 'subject_id'=> 2048],
//...
];
Model::insert($data); // Eloquent approach
DB::table('table')->insert($data); // Query Builder approach
In your case you already have the data within the $query
variable.
Use reindex
to get all columns you need. It'll preserve the ones that are already there and put in empty columns otherwise.
p = p.reindex(columns=['1Sun', '2Mon', '3Tue', '4Wed', '5Thu', '6Fri', '7Sat'])
So, your entire code example should look like this:
df = pd.read_csv(CsvFileName)
p = df.pivot_table(index=['Hour'], columns='DOW', values='Changes', aggfunc=np.mean).round(0)
p.fillna(0, inplace=True)
columns = ["1Sun", "2Mon", "3Tue", "4Wed", "5Thu", "6Fri", "7Sat"]
p = p.reindex(columns=columns)
p[columns] = p[columns].astype(int)
You can do it very easily with a Cloud Management software -like enStratus, RightScale or Scalr (disclaimer: I work there). With the cloned farm you can:
You can create a Global Class
like this:
public class GlobalClass extends Application{
private String name;
private String email;
public String getName() {
return name;
}
public void setName(String aName) {
name = aName;
}
public String getEmail() {
return email;
}
public void setEmail(String aEmail) {
email = aEmail;
}
}
Then define it in the manifest:
<application
android:name="com.example.globalvariable.GlobalClass" ....
Now you can set values to global variable like this:
final GlobalClass globalVariable = (GlobalClass) getApplicationContext();
globalVariable.setName("Android Example context variable");
You can get those values like this:
final GlobalClass globalVariable = (GlobalClass) getApplicationContext();
final String name = globalVariable.getName();
Please find complete example from this blog Global Variables
In addition to answer by kch (I didn't find how to leave a comment to that, sorry):
You don't have to specify variables as ENV
variables before the rake
command. You can just set them as usual command line parameters like that:
rake mytask var=foo
and access those from your rake file as ENV variables like such:
p ENV['var'] # => "foo"
There's a very simple way if you got your APK allready on your Smartphone. Just use one of these APPs:
jQuery UI extends the jQuery native toggleClass
to take a second optional parameter: duration
toggleClass( class, [duration] )
lambda should be useful for this case. For example,
create function y=x+1
y=lambda x:x+1
call the function
y(1)
then return 2
.
you can use something like this
var my_array = [1,2,3,4,5,6];_x000D_
delete my_array[4];_x000D_
console.log(my_array.filter(function(a){return typeof a !== 'undefined';})); // [1,2,3,4,6]
_x000D_
I know its too late but this solution is working perfect for both .net framework and .net core:
@System.Web.HttpUtility.JavaScriptStringEncode()
The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.
The way you get your original array back is by using Convert.FromBase64String
:
byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);
I too had this issue, however nothing I tried above and in several other posts worked.. except for this.
For me, I changed the bundle identifier since we have a different bundle ID for distribution versus development.
My hardware is allowed on this provision and my team account is valid but it was throwing the above error on some other framework.
Turns out that I needed to completely remove the old version of the app completely from my phone. And not just deleting it the standard way.
Solution :
Evidently on installing the same app under the same team under a different bundle ID, if your not starting completely from scratch, there are some references to frameworks that get muddied.
Hope this helps someone.
Given that what you want is to determine the full id of the element based upon just the prefix, you're going to have to do a search of the entire DOM (or at least, a search of an entire subtree if you know of some element that is always guaranteed to contain your target element). You can do this with something like:
function findChildWithIdLike(node, prefix) {
if (node && node.id && node.id.indexOf(prefix) == 0) {
//match found
return node;
}
//no match, check child nodes
for (var index = 0; index < node.childNodes.length; index++) {
var child = node.childNodes[index];
var childResult = findChildWithIdLike(child, prefix);
if (childResult) {
return childResult;
}
}
};
Here is an example: http://jsfiddle.net/xwqKh/
Be aware that dynamic element ids like the ones you are working with are typically used to guarantee uniqueness of element ids on a single page. Meaning that it is likely that there are multiple elements that share the same prefix. Probably you want to find them all.
If you want to find all of the elements that have a given prefix, instead of just the first one, you can use something like what is demonstrated here: http://jsfiddle.net/xwqKh/1/

Think about somebody doing help(yourmodule)
at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help
in terms of amount of information). So if you have in x.py

class Blah(object):
"""This class does blah blah."""
then:
>>> import x; help(x)
shows:
Help on module x:

As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).
I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.
I think your problem can be solved using a simple symbolic link, but you are creating the symbolic link to the wrong file. As far as I know virtualenv is installed to /Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenv
, (you can change the numbers for your Python version) so the command for creating the symbolic link should be:
ln -s /Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenv /usr/local/bin/virtualenv
I did a bit of searching and found that if one is being pedantic then yes it might be considered useless...in particular situations...it depends on how time sensitive your requirements are...
Check out this quote from the Java Sun site:
The real-time clock and System.nanoTime() are both based on the same system call and thus the same clock.
With Java RTS, all time-based APIs (for example, Timers, Periodic Threads, Deadline Monitoring, and so forth) are based on the high-resolution timer. And, together with real-time priorities, they can ensure that the appropriate code will be executed at the right time for real-time constraints. In contrast, ordinary Java SE APIs offer just a few methods capable of handling high-resolution times, with no guarantee of execution at a given time. Using System.nanoTime() between various points in the code to perform elapsed time measurements should always be accurate.
Java also has a caveat for the nanoTime() method:
This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time. The value returned represents nanoseconds since some fixed but arbitrary time (perhaps in the future, so values may be negative). This method provides nanosecond precision, but not necessarily nanosecond accuracy. No guarantees are made about how frequently values change. Differences in successive calls that span greater than approximately 292.3 years (263 nanoseconds) will not accurately compute elapsed time due to numerical overflow.
It would seem that the only conclusion that can be drawn is that nanoTime() cannot be relied upon as an accurate value. As such, if you do not need to measure times that are mere nano seconds apart then this method is good enough even if the resulting returned value is negative. However, if you're needing higher precision, they appear to recommend that you use JAVA RTS.
So to answer your question...no nanoTime() is not useless....its just not the most prudent method to use in every situation.
The problem here is that in your code the program is calling 'null.length()' which is not defined if the argument passed to the function is null. That's why the exception is thrown.
While creating a fragment transaction, make sure to add the following code.
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
Also make sure, to commit the transaction after adding it to backstack
I was hoping for an über one liner like:
$("img.screenshot").attr("src", $(this).replace("foo", "bar"));
IntelliJ IDEA Plugins / GenerateSerialVersionUID https://plugins.jetbrains.com/plugin/?idea&id=185
very nice, very easy to install. you can install that from plugins menu, select install from disk, select the jar file you unpacked in the lib folder. restart, control + ins, and it pops up to generate serial UID from menu. love it. :-)

Moq cannot mock non-virtual methods and sealed classes. While running a test using mock object, MOQ actually creates an in-memory proxy type which inherits from your "XmlCupboardAccess" and overrides the behaviors that you have set up in the "SetUp" method. And as you know in C#, you can override something only if it is marked as virtual which isn't the case with Java. Java assumes every non-static method to be virtual by default.
Another thing I believe you should consider is introducing an interface for your "CupboardAccess" and start mocking the interface instead. It would help you decouple your code and have benefits in the longer run.
Lastly, there are frameworks like : TypeMock and JustMock which work directly with the IL and hence can mock non-virtual methods. Both however, are commercial products.
In EclipseLink to get the SQL for a specific Query at runtime you can use the DatabaseQuery API:
Query query = em.createNamedQuery("findMe");
Session session = em.unwrap(JpaEntityManager.class).getActiveSession();
DatabaseQuery databaseQuery = ((EJBQueryImpl)query).getDatabaseQuery();
databaseQuery.prepareCall(session, new DatabaseRecord());
String sqlString = databaseQuery.getSQLString();
This SQL will contain ? for parameters. To get the SQL translated with the arguments you need a DatabaseRecord with the parameter values.
DatabaseRecord recordWithValues= new DatabaseRecord();
recordWithValues.add(new DatabaseField("param1"), "someValue");
String sqlStringWithArgs =
databaseQuery.getTranslatedSQLString(session, recordWithValues);

You can call the get()
method of AsyncTask
(or the overloaded get(long, TimeUnit)
). This method will block until the AsyncTask
has completed its work, at which point it will return you the Result
.
It would be wise to be doing other work between the creation/start of your async task and calling the get
method, otherwise you aren't utilizing the async task very efficiently.
Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.
Use the subplots_adjust()
function to move the bottom of the subplot up:
fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.
Then play with the offset in the legend bbox_to_anchor
part of the legend command, to get the legend box where you want it. Some combination of setting the figsize
and using the subplots_adjust(bottom=...)
should produce a quality plot for you.
Alternative: I simply changed the line:
fig = plt.figure(1)
to:
fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')
and changed
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))
to
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))
and it shows up fine on my screen (a 24-inch CRT monitor).
Here figsize=(M,N)
sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport
option when including graphics.
var currentDateTime = dateTime.Now();
var date=currentDateTime.Date;
A pull request is just that: a request to merge one branch into another.
Your pull request doesn't "contain" anything, it's just a marker saying "please merge this branch into that one".
The set of changes the PR shows in the web UI is just the changes between the target branch and your feature branch. To modify your pull request, you must modify your feature branch, probably with a force push to the feature branch.
In your case, you'll probably want to amend your commit. Not sure about your exact situation, but some combination of interactive rebase and add -p
should sort you out.

Thanks HansUp for your answer, it is very helpful and it works!
I found three patterns working in Access, yours is the best, because it works in all cases.
INNER JOIN, your variant. I will call it "closed set pattern". It is possible to join more than two tables to the same table with good performance only with this pattern.
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM
((class
INNER JOIN person AS cr
ON class.C_P_ClassRep=cr.P_Nr
)
INNER JOIN person AS cr2
ON class.C_P_ClassRep2nd=cr2.P_Nr
)
;
INNER JOIN "chained-set pattern"
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM person AS cr
INNER JOIN ( class
INNER JOIN ( person AS cr2
) ON class.C_P_ClassRep2nd=cr2.P_Nr
) ON class.C_P_ClassRep=cr.P_Nr
;
CROSS JOIN with WHERE
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM class, person AS cr, person AS cr2
WHERE class.C_P_ClassRep=cr.P_Nr AND class.C_P_ClassRep2nd=cr2.P_Nr
;
You are doing mistake in "configuration_page.jsp" file. here in this file , function loadXMLDoc() 's line number 2 should be like this:
var config=document.getElementsByName('configselect').value;
because you have declared only the name
attribute in your <select>
tag. So you should get this element by name.
After correcting this, it will run without any JavaScript error
From memory, you call stringstream::str()
to get the std::string
value out.
ActiveWorkbook.FullName would be better I think, in case you have the VBA Macro stored in another Excel Workbook, but you want to get the details of the Excel you are editing, not where the Macro resides.
If they reside in the same file, then it does not matter, but if they are in different files, and you want the file where the Data is rather than where the Macro is, then ActiveWorkbook is the one to go for, because it deals with both scenarios.
First of all, you should use none of them. You are using wrapper
type, which should rarely be used in case you have a primitive type.
So, you should use boolean
rather.
Further, we initialize the boolean
variable to false
to hold an initial default value which is false. In case you have declared it as instance variable, it will automatically be initialized to false
.
But, its completely upto you, whether you assign a default value or not. I rather prefer to initialize them at the time of declaration.
But if you are immediately assigning to your variable, then you can directly assign a value to it, without having to define a default
value.
So, in your case I would use it like this: -
boolean isMatch = email1.equals (email2);
Using extended slice syntax
word = input ("Type a word which you want to reverse: ")
def reverse(word):
word = word[::-1]
return word
print (reverse(word))
You can try this:
$( "#data" ).val([ "100", "101" ]);
The only good use case for recursion mutex is when an object contains multiple methods. When any of the methods modify the content of the object, and therefore must lock the object before the state is consistent again.
If the methods use other methods (ie: addNewArray() calls addNewPoint(), and finalizes with recheckBounds()), but any of those functions by themselves need to lock the mutex, then recursive mutex is a win-win.
For any other case (solving just bad coding, using it even in different objects) is clearly wrong!
The accepted answer previously contained new Buffer()
, which is considered a security issue in node versions greater than 6 (although it seems likely for this usecase that the input can always be coerced to a string).
The Buffer
constructor is deprecated according to the documentation.
Here is an example of a vulnerability that can result from using it in the ws library.
The code snippets should read:
console.log(Buffer.from("Hello World").toString('base64'));
console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii'));
After this answer was written, it has been updated and now matches this.
How to use conditional in ng-class:
Solution 1:
<i ng-class="{'icon-autoscroll': autoScroll, 'icon-autoscroll-disabled': !autoScroll}"></i>
Solution 2:
<i ng-class="{true: 'icon-autoscroll', false: 'icon-autoscroll-disabled'}[autoScroll]"></i>
Solution 3 (angular v.1.1.4+ introduced support for ternary operator):
<i ng-class="autoScroll ? 'icon-autoscroll' : 'icon-autoscroll-disabled'"></i>
class Mammal(object):
#mammal stuff
class Dog(Mammal):
#doggie stuff
You're close. A really simple solution is just to get the length from the 'run' objects returned. No need to bother with 'load' or 'loads':
len(data['result'][0]['run'])
Ok I was running into the same issue. What I failed to notice is that I was using json_decode() instead of using json_encode() so for those who are going to come here please make sure you are using the right function, which is json_encode()
Note: Depends on what you are working on but make sure you are using the right function.
Unfortunately MySQL does not support SQL check constraints. You can define them in your DDL query for compatibility reasons but they are just ignored.
There is a simple alternative
You can create BEFORE INSERT
and BEFORE UPDATE
triggers which either cause an error or set the field to its default value when the requirements of the data are not met.
Example for BEFORE INSERT
working after MySQL 5.5
DELIMITER $$
CREATE TRIGGER `test_before_insert` BEFORE INSERT ON `Test`
FOR EACH ROW
BEGIN
IF CHAR_LENGTH( NEW.ID ) < 4 THEN
SIGNAL SQLSTATE '12345'
SET MESSAGE_TEXT := 'check constraint on Test.ID failed';
END IF;
END$$
DELIMITER ;
Prior to MySQL 5.5 you had to cause an error, e.g. call a undefined procedure.
In both cases this causes an implicit transaction rollback. MySQL does not allow the ROLLBACK statement itself within procedures and triggers.
If you don't want to rollback the transaction ( INSERT / UPDATE should pass even with a failed "check constraint" you can overwrite the value using SET NEW.ID = NULL
which will set the id to the fields default value, doesn't really make sense for an id tho
Edit: Removed the stray quote.
Concerning the :=
operator:
Unlike
=
, the:=
operator is never interpreted as a comparison operator. This means you can use:=
in any valid SQL statement (not just in SET statements) to assign a value to a variable.
https://dev.mysql.com/doc/refman/5.6/en/assignment-operators.html
Concerning backtick identifier quotes:
The identifier quote character is the backtick (“`”)
If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks
It looks like you want:
public static string GetRandomBits()
Without static
, you would need an object before you can call the GetRandomBits()
method. However, since the implementation of GetRandomBits()
does not depend on the state of any Program
object, it's best to declare it static
.
I have similar formula for the First and Last Day
The First Day of the month
FirstDay = DateSerial(Year(Date),Month(Date),1)
The zero Day of the next month is the Last Day of the month
LastDay = DateSerial(Year(Date),Month(Date)+ 1,0)

As all the previous answers indicated, it's very well possible, and pretty easy in newer iOS versions.
I know this is not a technical answer, but since a lot of people do make it wrong (thus effectively violating licenses which may cost you a lot of money if you're being sued), let me strengthen one caveat here: Embedding a custom font in an iOS (or any other kind) app is basically redistributing the font. Most licenses for commercial fonts do forbid redistribution, so please make sure you're acting according to the license.
