There are a few other choices in case the Adobe ActiveX isn't what you're looking for (since Acrobat must be present on the user machine and you can't ship it yourself).
For creating the PDF preview, first have a look at some other discussions on the subject on StackOverflow:
In the last two I talk about a few things you can try:
You can get a commercial renderer (PDFViewForNet, PDFRasterizer.NET, ABCPDF, ActivePDF, XpdfRasterizer and others in the other answers...).
Most are fairly expensive though, especially if all you care about is making a simple preview/thumbnails.
In addition to Omar Shahine's code snippet, there is a CodeProject article that shows how to use the Adobe ActiveX, but it may be out of date, easily broken by new releases and its legality is murky (basically it's ok for internal use but you can't ship it and you can't use it on a server to produce images of PDF).
You could have a look at the source code for SumatraPDF, an OpenSource PDF viewer for windows.
There is also Poppler, a rendering engine that uses Xpdf as a rendering engine. All of these are great but they will require a fair amount of commitment to make make them work and interface with .Net and they tend to be be distributed under the GPL.
You may want to consider using GhostScript as an interpreter because rendering pages is a fairly simple process.
The drawback is that you will need to either re-package it to install it with your app, or make it a pre-requisite (or at least a part of your install process).
It's not a big challenge, and it's certainly easier than having to massage the other rendering engines into cooperating with .Net.
I did a small project that you will find on the Developer Express forums as an attachment.
Be careful of the license requirements for GhostScript through.
If you can't leave with that then commercial software is probably your only choice.
The code won't work without an icon. So, add the setSmallIcon
call to the builder chain like this for it to work:
.setSmallIcon(R.drawable.icon)
Android 8 introduced a new requirement of setting the channelId
property by using a NotificationChannel
.
private NotificationManager mNotificationManager;
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(mContext.getApplicationContext(), "notify_001");
Intent ii = new Intent(mContext.getApplicationContext(), RootActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, ii, 0);
NotificationCompat.BigTextStyle bigText = new NotificationCompat.BigTextStyle();
bigText.bigText(verseurl);
bigText.setBigContentTitle("Today's Bible Verse");
bigText.setSummaryText("Text in detail");
mBuilder.setContentIntent(pendingIntent);
mBuilder.setSmallIcon(R.mipmap.ic_launcher_round);
mBuilder.setContentTitle("Your Title");
mBuilder.setContentText("Your text");
mBuilder.setPriority(Notification.PRIORITY_MAX);
mBuilder.setStyle(bigText);
mNotificationManager =
(NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
// === Removed some obsoletes
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
String channelId = "Your_channel_id";
NotificationChannel channel = new NotificationChannel(
channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_HIGH);
mNotificationManager.createNotificationChannel(channel);
mBuilder.setChannelId(channelId);
}
mNotificationManager.notify(0, mBuilder.build());
BrowserWindow
only has an effect on Windows and Linux platforms. you have to package the .icns for max
To set the icon on OS X using electron-packager
, set the icon using the --icon switch.
It will need to be in .icns format for OS X. There is an online icon converter which can create this file from your .png.
--icon
switch. Here is what you can do.
build
in your project directory and put the .icns
the icon in the directory as named icon.icns
.electron-builder --dir
.You will find your application icon will be automatically picked up from that directory location and used for an application while packaging.
Note: The given answer is for recent version of
electron-builder
and tested with electron-builder v21.2.0
depending on you application, i suggest using FLOAT(9,6)
spatial keys will give you more features, but in by production benchmarks the floats are much faster than the spatial keys. (0,01 VS 0,001 in AVG)
Changing Floating action button background color by using below line
app:backgroundTint="@color/blue"
Changing Floating action button icon color
android:tint="@color/white"
Disabling all other options in authentication tab of iis except windows authentication resolved my issue. Please check..
Steps:
Please check this and let me know the feedback. It worked for me. hope it will work for you also..
In case you're reading text from the clipboard in a Chrome extension, with 'clipboardRead' permission allowed, you can use the below code:
function readTextFromClipboardInChromeExtension() {
var ta = $('<textarea/>');
$('body').append(ta);
ta.focus();
document.execCommand('paste');
var text = ta.val();
ta.blur();
ta.remove();
return text;
}
So if you just have a string and not a window.location you could use...
String.prototype.toUrl = function(){
if(!this && 0 < this.length)
{
return undefined;
}
var original = this.toString();
var s = original;
if(!original.toLowerCase().startsWith('http'))
{
s = 'http://' + original;
}
s = this.split('/');
var protocol = s[0];
var host = s[2];
var relativePath = '';
if(s.length > 3){
for(var i=3;i< s.length;i++)
{
relativePath += '/' + s[i];
}
}
s = host.split('.');
var domain = s[s.length-2] + '.' + s[s.length-1];
return {
original: original,
protocol: protocol,
domain: domain,
host: host,
relativePath: relativePath,
getParameter: function(param)
{
return this.getParameters()[param];
},
getParameters: function(){
var vars = [], hash;
var hashes = this.original.slice(this.original.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
};};
How to use.
var str = "http://en.wikipedia.org/wiki/Knopf?q=1&t=2";
var url = str.toUrl;
var host = url.host;
var domain = url.domain;
var original = url.original;
var relativePath = url.relativePath;
var paramQ = url.getParameter('q');
var paramT = url.getParamter('t');
Where is this info kept ("this connection is between computer
A
and serverF
")?
A TCP connection is recognized by source IP and port and destination IP and port. Your OS, all intermediate session-aware devices and the server's OS will recognize the connection by this.
HTTP works with request-response: client connects to server, performs a request and gets a response. Without keep-alive, the connection to an HTTP server is closed after each response. With HTTP keep-alive you keep the underlying TCP connection open until certain criteria are met.
This allows for multiple request-response pairs over a single TCP connection, eliminating some of TCP's relatively slow connection startup.
When The IIS (F) sends keep alive header (or user sends keep-alive) , does it mean that (E,C,B) save a connection
No. Routers don't need to remember sessions. In fact, multiple TCP packets belonging to same TCP session need not all go through same routers - that is for TCP to manage. Routers just choose the best IP path and forward packets. Keep-alive is only for client, server and any other intermediate session-aware devices.
which is only for my session ?
Does it mean that no one else can use that connection
That is the intention of TCP connections: it is an end-to-end connection intended for only those two parties.
If so - does it mean that keep alive-header - reduce the number of overlapped connection users ?
Define "overlapped connections". See HTTP persistent connection for some advantages and disadvantages, such as:
if so , for how long does the connection is saved to me ? (in other words , if I set keep alive- "keep" till when?)
An typical keep-alive response looks like this:
Keep-Alive: timeout=15, max=100
See Hypertext Transfer Protocol (HTTP) Keep-Alive Header for example (a draft for HTTP/2 where the keep-alive header is explained in greater detail than both 2616 and 2086):
A host sets the value of the timeout
parameter to the time that the host will allows an idle connection to remain open before it is closed. A connection is idle if no data is sent or received by a host.
The max
parameter indicates the maximum number of requests that a client will make, or that a server will allow to be made on the persistent connection. Once the specified number of requests and responses have been sent, the host that included the parameter could close the connection.
However, the server is free to close the connection after an arbitrary time or number of requests (just as long as it returns the response to the current request). How this is implemented depends on your HTTP server.
This worked for me
I recently had the same problem and used the solution provided by Harry Joy. That solution only works with with zero-based enumaration though. I also wouldn't consider it save as it doesn't deal with indexes that are out of range.
The solution I ended up using might not be as simple but it's completely save and won't hurt the performance of your code even with big enums:
public enum Example {
UNKNOWN(0, "unknown"), ENUM1(1, "enum1"), ENUM2(2, "enum2"), ENUM3(3, "enum3");
private static HashMap<Integer, Example> enumById = new HashMap<>();
static {
Arrays.stream(values()).forEach(e -> enumById.put(e.getId(), e));
}
public static Example getById(int id) {
return enumById.getOrDefault(id, UNKNOWN);
}
private int id;
private String description;
private Example(int id, String description) {
this.id = id;
this.description= description;
}
public String getDescription() {
return description;
}
public int getId() {
return id;
}
}
If you are sure that you will never be out of range with your index and you don't want to use UNKNOWN
like I did above you can of course also do:
public static Example getById(int id) {
return enumById.get(id);
}
This was bugging me too, since this was a standard feature in Sublime Text 2, but somehow automatic indentation no longer worked in Sublime Text 3 for HTML files.
My solution was to find the Miscellaneous.tmPreferences file from Sublime Text 2 (found under %AppData%/Roaming/Sublime Text 2/Packages/HTML) and copy those settings to the same file for ST3.
Now package handling has been made more difficult for ST3, but luckily you can just add the files to your %AppData%/Roaming/Sublime Text 3/Packages folder and they overwrite default settings in the install directory. Just save this file as "%AppData%/Roaming/Sublime Text 3/Packages/HTML/Miscellaneous.tmPreferences" and auto indent works again like it did in ST2.

I got mine working after I realised that the lambda authoriser was failing and for some unknown reason that was being translated into a CORS error. A simple fix to my authoriser (and some authoriser tests that I should have added in the first place) and it worked. For me the API Gateway action 'Enable CORS' was required. This added all the headers and other settings I needed in my API.

Perhaps the best two browser techs for this are Canvas, with Flash as a back up.
We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.
With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.

You can use this code instead.
<div id="" style="overflow-y:scroll; overflow-x:hidden; height:400px;">
overflow-x: The overflow-x property specifies what to do with the left/right edges of the content - if it overflows the element's content area.
overflow-y: The overflow-y property specifies what to do with the top/bottom edges of the content - if it overflows the element's content area.
Values
visible: Default value. The content is not clipped, and it may be rendered outside the content box.
hidden: The content is clipped - and no scrolling mechanism is provided.
scroll: The content is clipped and a scrolling mechanism is provided.
auto: Should cause a scrolling mechanism to be provided for overflowing boxes.
initial: Sets this property to its default value.
inherit Inherits this property from its parent element.
As with the release of iOS7
you no longer need to use an external framework or library. The iOS ecosystem with AVFoundation now fully supports scanning almost every code from QR over EAN to UPC.
Just have a look at the Tech Note and the AVFoundation programming guide. AVMetadataObjectTypeQRCode
is your friend.
Here is a nice tutorial which shows it step by step: iPhone QR code scan library iOS7
Just a little example on how to set it up:

[self.session addOutput:self.output];
[self.session addInput:self.input];
[self.output setMetadataObjectsDelegate:self queue:dispatch_get_main_queue()];
self.output.metadataObjectTypes = @[AVMetadataObjectTypeQRCode];

In my code I have no direct access to the 'preparedStatement' so I cannot use batch, I just pass it the query and a list of parameters. The trick however is to create a variable length insert statement, and a LinkedList of parameters. The effect is the same as the top example, with variable parameter input length.See below (error checking omitted). Assuming 'myTable' has 3 updatable fields: f1, f2 and f3
String []args={"A","B","C", "X","Y","Z" }; // etc, input list of triplets
final String QUERY="INSERT INTO [myTable] (f1,f2,f3) values ";
LinkedList params=new LinkedList();
String comma="";
StringBuilder q=QUERY;
for(int nl=0; nl< args.length; nl+=3 ) { // args is a list of triplets values
params.add(args[nl]);
params.add(args[nl+1]);
params.add(args[nl+2]);
q.append(comma+"(?,?,?)");
comma=",";
}
int nr=insertIntoDB(q, params);
in my DBInterface class I have:
int insertIntoDB(String query, LinkedList <String>params) {
preparedUPDStmt = connectionSQL.prepareStatement(query);
int n=1;
for(String x:params) {
preparedUPDStmt.setString(n++, x);
}
int updates=preparedUPDStmt.executeUpdate();
return updates;
}
Do it like this:
$foo = new stdClass();
$foo->{"bar"} = '1234';
now try:
echo $foo->bar; // should display 1234
If you have control over running the cscript executable then run the X:\windows\syswow64\cscript.exe
version which is the 32bit implementation.
You can use typeof(N)
to get the actual object type, but what you want to do is check the tag, not the type of the DOM element.
In that case, use the elem.tagName
or elem.nodeName
property.
if you want to get really creative, you can use a dictionary of tagnames and anonymous closures instead if a switch or if/else.
Here is an another answer: You need to format the tow dates to fit the same fromat to be able to compare them as string.
Date questionDate = question.getStartDate();
Date today = new Date();
SimpleDateFormat dateFormatter = new SimpleDateFormat ("yyyy/MM/dd");
String questionDateStr = dateFormatter.format(questionDate);
String todayStr = dateFormatter.format(today);
if(questionDateStr.equals(todayStr)) {
System.out.println("Both are equals");
}
If you are working on a windows forms project you can try the following:
Add items to the ListBox
as KeyValuePair
objects:
listBox.Items.Add(new KeyValuePair(key, value);
Then you will be able to retrieve them the following way:
KeyValuePair keyValuePair = listBox.Items[index];
var value = keyValuePair.Value;
clearfix
should contain the floating elements but in your html you have added clearfix
only after floating right that is your pull-right
so you should do like this:
<div class="clearfix">
<div id="sidebar">
<ul>
<li>A</li>
<li>A</li>
<li>C</li>
<li>D</li>
<li>E</li>
<li>F</li>
<li>...</li>
<li>Z</li>
</ul>
</div>
<div id="main">
<div>
<div class="pull-right">
<a>RIGHT</a>
</div>
</div>
<div>MOVED BELOW Z</div>
</div>
Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden;
as you have done in your main.
Try this.
using System.Xml.Linq;
void Main()
{
StringBuilder result = new StringBuilder();
//Load xml
XDocument xdoc = XDocument.Load("data.xml");
//Run query
var lv1s = from lv1 in xdoc.Descendants("level1")
select new {
Header = lv1.Attribute("name").Value,
Children = lv1.Descendants("level2")
};
//Loop through results
foreach (var lv1 in lv1s){
result.AppendLine(lv1.Header);
foreach(var lv2 in lv1.Children)
result.AppendLine(" " + lv2.Attribute("name").Value);
}
Console.WriteLine(result);
}
To add the new repo location,
git remote add new_repo_name new_repo_url
Then push the content to the new location
git push new_repo_name master
Finally remove the old one
git remote rm origin
After that you can do what bdonlan said and edit the.git/config file to change the new_repo_name to origin. If you don't remove the origin (original remote repository), you can simply just push changes to the new repo with
git push new_repo_name master
I think the easiest way is to divide two integers and increase by one :
int r = list.Count() / 10;
r += (list.Count() % 10 == 0 ? 0 : 1);
No need of libraries or functions.
edited with the right code.
In C++, there are three distinct character types:
char
signed char
unsigned char
If you are using character types for text, use the unqualified char
:
'a'
or '0'
."abcde"
It also works out as a number value, but it is unspecified whether that value is treated as signed or unsigned. Beware character comparisons through inequalities - although if you limit yourself to ASCII (0-127) you're just about safe.
If you are using character types as numbers, use:
signed char
, which gives you at least the -127 to 127 range. (-128 to 127 is common)unsigned char
, which gives you at least the 0 to 255 range."At least", because the C++ standard only gives the minimum range of values that each numeric type is required to cover. sizeof (char)
is required to be 1 (i.e. one byte), but a byte could in theory be for example 32 bits. sizeof
would still be report its size as 1
- meaning that you could have sizeof (char) == sizeof (long) == 1
.

Since Bootstrap 3 you have to use checkbox-inline and radio-inline classes on the label.
This takes care of vertical alignment.
<label class="checkbox-inline">

<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1

SOAP web service always make a POST operation whereas using REST you can choose specific HTTP methods like GET, POST, PUT, and DELETE.
Example: to get an item using SOAP you should create a request XML, but in the case of REST you can just specify the item id in the URL itself.
$("body").stop().animate({
scrollTop: 0
}, 500, 'swing', function () {
console.log(confirm('Like This'))
}
);

Create a User-Defined TableType
in your database:
CREATE TYPE [dbo].[MyTableType] AS TABLE(
[Id] int NOT NULL,
[Name] [nvarchar](128) NULL
)
and define a parameter in your Stored Procedure
:
CREATE PROCEDURE [dbo].[InsertTable]
@myTableType MyTableType readonly
AS
BEGIN
insert into [dbo].Records select * from @myTableType
END
and send your DataTable
directly to sql server:
using (var command = new SqlCommand("InsertTable") {CommandType = CommandType.StoredProcedure})
{
var dt = new DataTable(); //create your own data table
command.Parameters.Add(new SqlParameter("@myTableType", dt));
SqlHelper.Exec(command);
}
To edit the values inside stored-procedure, you can declare a local variable with the same type and insert input table into it:
DECLARE @modifiableTableType MyTableType
INSERT INTO @modifiableTableType SELECT * FROM @myTableType
Then, you can edit @modifiableTableType
:
UPDATE @modifiableTableType SET [Name] = 'new value'
MongoDB needs data directory to store data.
Default path is /data/db
When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx
permission to user.
If you want to change the path of your data directory then you should specify it while starting mongod server like,
mongod --dbpath /data/<path> --port <port no>
This should help you start your mongod server with custom path and port.
Use JOIN to join the subqueries and use ON to say where the rows from each subquery must match:
SELECT T1.col_a, T1.col_b, T2.col_c
FROM (SELECT col_a, col_b, ...etc...) AS T1
JOIN (SELECT col_a, col_c, ...etc...) AS T2
ON T1.col_a = T2.col_a
If there are some values of col_a that are in T1 but not in T2, you can use a LEFT OUTER JOIN instead.
Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.
From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).
I do this quite often on results returned from a query..
e.g.
// $MyQueryResult is an array of results from a query
foreach ($MyQueryResult as $key=>$value)
{
${$key}=$value;
}
Now I can just use $MyFieldname (which is easier in echo statements etc) rather than $MyQueryResult['MyFieldname']
Yep, it's probably lazy, but I've never had any problems.
my recipe:
<form>
<input type=hidden name=action value=login><!-- the magic! -->
<input type=text name=email>
<input type=text name=password>
<input type=submit name=action value=login>
<input type=submit name=action value="forgot password">
</form>
It will send the default hidden field if none of the buttons are 'clicked'.
if they are clicked, they have preference and it's value is passed.
Set its layout_height="0dp"
*, add a blank View
beneath it (or blank ImageView
or just a FrameLayout
) with a layout_height
also equal to 0dp
, and set both Views to have a layout_weight="1"
This will stretch each View equally as it fills the screen. Since both have the same weight, each will take 50% of the screen.
*See adamp's comment for why that works and other really helpful tidbits.

There's no simple answer to this question. Apple's mobile version of WebKit, used in iPhones, iPod Touches, and iPads, will scale the page to fit the screen, at which point the user can zoom in and out freely.
That said, you can design your page to minimize the amount of zooming necessary. Your best bet is to make the width and height the same as the lower resolution of the iPad, since you don't know which way it's oriented; in other words, you would make your page 768x768, so that it will fit well on the iPad's screen whether it's oriented to be 1024x768 or 768x1024.
More importantly, you'd want to design your page with big controls with lots of space that are easy to hit with your thumbs - you could easily design a 768x768 page that was very cluttered and therefore required lots of zooming. To accomplish this, you'll likely want to divide your controls among a number of web pages.
On the other hand, it's not the most worthwhile pursuit. If while designing you find opportunities to make your page more "finger-friendly", then go for it...but the reality is that iPad users are very comfortable with moving around and zooming in and out of the page to get to things because it's necessary on most web sites. If anything, you probably want to design it so that it's conducive to this type of navigation.
Make boxes with relevant grouped data that can be easily double-tapped to focus on, and keep related controls close to each other. iPad users will most likely appreciate a page that facilitates the familiar zoom-and-pan navigation they're accustomed to more than they will a page that has fewer controls so that they don't have to.
As of spring boot 2 the server.contextPath
property is deprecated. Instead you should use server.servlet.contextPath
.
So in your application.properties file add:
server.servlet.contextPath=/myWebApp
For more details see: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#servlet-specific-server-properties
The usage of yield is similar to the keyword return, except that it will return a generator. And the generator object will only traverse once.
yield has two benefits:
There is another clear explanation maybe help you.
Instead of instantiating the FileUpload
in your code behind file, just declare it in your markup file (.aspx file):
<asp:FileUpload ID="fileUpload" runat="server" />
Then you will be able to access all of the properties of the control, such as HasFile
.
Despite that the other answers are correct and thoroughly explained, I found some difficulties understanding them. Here is the method I used (Taken from here):
openssl pkcs12 -in filename.pfx -out cert.pem -nodes
Extracts the private key form a PFX to a PEM file:
openssl pkcs12 -in filename.pfx -nocerts -out key.pem
Exports the certificate (includes the public key only):
openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
Removes the password (paraphrase) from the extracted private key (optional):
openssl rsa -in key.pem -out server.key
In the above solution, repeated here:
f = open('file.txt', 'r')
try:
# do stuff with f
finally:
f.close()
if something bad happens (you never know ...) after opening the file successfully and before the try, the file will not be closed, so a safer solution is:
f = None
try:
f = open('file.txt', 'r')
# do stuff with f
finally:
if f is not None:
f.close()
If you would like to do it in a more functional way (immutability) I would return a new date object instead of modifying the existing and I wouldn't alter the prototype but create a standalone function. Here is the example:
//JS
function addHoursToDate(date, hours) {
return new Date(new Date(date).setHours(date.getHours() + hours));
}
//TS
function addHoursToDate(date: Date, hours: number): Date {
return new Date(new Date(date).setHours(date.getHours() + hours));
}
let myDate = new Date();
console.log(myDate)
console.log(addHoursToDate(myDate,2))

There are two ways to capture network traffic directly from an Android emulator:
Copy and run an ARM-compatible tcpdump binary on the emulator, writing output to the SD card, perhaps (e.g. tcpdump -s0 -w /sdcard/emulator.cap
).
Run emulator -tcpdump emulator.cap -avd my_avd
to write all the emulator's traffic to a local file on your PC
In both cases you can then analyse the pcap file with tcpdump or Wireshark as normal.
To answer the original question - there are various ways to do this, but the following would be the simplest.
If you already have a handle to the child node that you want to remove, i.e. you have a JavaScript variable that holds a reference to it:
myChildNode.parentNode.removeChild(myChildNode);
Obviously, if you are not using one of the numerous libraries that already do this, you would want to create a function to abstract this out:
function removeElement(node) {
node.parentNode.removeChild(node);
}
EDIT: As has been mentioned by others: if you have any event handlers wired up to the node you are removing, you will want to make sure you disconnect those before the last reference to the node being removed goes out of scope, lest poor implementations of the JavaScript interpreter leak memory.

One solution would be to use the key of your items to remove them -- you can both the keys and the values, when looping using foreach.
For instance :
$arr = array(
'a' => 123,
'b' => 456,
'c' => 789,
);
foreach ($arr as $key => $item) {
if ($item == 456) {
unset($arr[$key]);
}
}
var_dump($arr);
Will give you this array, in the end :
array
'a' => int 123
'c' => int 789
Which means that, in your case, something like this should do the trick :
foreach($images as $key => $image)
{
if($image == 'http://i27.tinypic.com/29yk345.gif' ||
$image == 'http://img3.abload.de/img/10nx2340fhco.gif' ||
$image == 'http://i42.tinypic.com/9pp2456x.gif')
{
unset($images[$key]);
}
}
To answer your question - nginx picks the first server if there's no match. See documentation:
If its value does not match any server name, or the request does not contain this header field at all, then nginx will route the request to the default server for this port. In the configuration above, the default server is the first one...
Now, if you wanted to have a default catch-all server that, say, responds with 404 to all requests, then here's how to do it:
server {
listen 80 default_server;
listen 443 ssl default_server;
server_name _;
ssl_certificate <path to cert>
ssl_certificate_key <path to key>
return 404;
}
Note that you need to specify certificate/key (that can be self-signed), otherwise all SSL connections will fail as nginx will try to accept connection using this default_server and won't find cert/key.
Unfortunately, it's not completely portable. It's usually integral, but it can be any "integer or real-floating type".
It is important to recognize that the copyright laws have changed and that for non-US sources, especially after the USA joining the Berne Convention on March 1, 1989, copyright registration in not necessary for enforcement of a copyright notice.
Here is a resumé quoted from the Cornell University Law School (copied on March 4, 2015 from https://www.law.cornell.edu/wex/copyright:
"Copyright
copyright: an overview
The U.S. Copyright Act, 17 U.S.C. §§ 101 - 810, is Federal legislation enacted by Congress under its Constitutional grant of authority to protect the writings of authors. See U.S. Constitution, Article I, Section 8. Changing technology has led to an ever expanding understanding of the word "writings." The Copyright Act now reaches architectural design, software, the graphic arts, motion pictures, and sound recordings. See § 106. As of January 1, 1978, all works of authorship fixed in a tangible medium of expression and within the subject matter of copyright were deemed to fall within the exclusive jurisdiction of the Copyright Act regardless of whether the work was created before or after that date and whether published or unpublished. See § 301. See also preemption.
The owner of a copyright has the exclusive right to reproduce, distribute, perform, display, license, and to prepare derivative works based on the copyrighted work. See § 106. The exclusive rights of the copyright owner are subject to limitation by the doctrine of "fair use." See § 107. Fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching, scholarship, or research is not copyright infringement. To determine whether or not a particular use qualifies as fair use, courts apply a multi-factor balancing test. See § 107.
Copyright protection subsists in original works of authorship fixed in any tangible medium of expression from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. See § 102. Copyright protection does not extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery. For example, if a book is written describing a new system of bookkeeping, copyright protection only extends to the author's description of the bookkeeping system; it does not protect the system itself. See Baker v. Selden, 101 U.S. 99 (1879).
According to the Copyright Act of 1976, registration of copyright is voluntary and may take place at any time during the term of protection. See § 408. Although registration of a work with the Copyright Office is not a precondition for protection, an action for copyright infringement may not be commenced until the copyright has been formally registered with the Copyright Office. See § 411.
Deposit of copies with the Copyright Office for use by the Library of Congress is a separate requirement from registration. Failure to comply with the deposit requirement within three months of publication of the protected work may result in a civil fine. See § 407. The Register of Copyrights may exempt certain categories of material from the deposit requirement.
In 1989 the U.S. joined the Berne Convention for the Protection of Literary and Artistic Works. In accordance with the requirements of the Berne Convention, notice is no longer a condition of protection for works published after March 1, 1989. This change to the notice requirement applies only prospectively to copies of works publicly distributed after March 1, 1989.
The Berne Convention also modified the rule making copyright registration a precondition to commencing a lawsuit for infringement. For works originating from a Berne Convention country, an infringement action may be initiated without registering the work with the U.S. Copyright Office. However, for works of U.S. origin, registration prior to filing suit is still required.
The federal agency charged with administering the act is the Copyright Office of the Library of Congress. See § 701 of the act. Its regulations are found in Parts 201 - 204 of title 37 of the Code of Federal Regulations."
If the execution planner says they're the same, they're the same. Use whichever one will make your intention more obvious -- in this case, the second.
Nothing was working for me.
PHP_EOL
. "\r\n";
$NEWLINE_RE = '/(\r\n)|\r|\n/'; // take care of all possible newline-encodings in input file
$var = preg_replace($NEWLINE_RE,'', $var);
Works for me:
$admin_email_Body = $admin_mail_body .'<br>' ."\r\n";
$admin_email_Body .= 'This is line 2 <br>' ."\r\n";
$admin_email_Body .= 'This is line 3 <br>' ."\r\n";
Your function return type is a single character (char
). You should return a pointer to the first element of the character array. If you can't use pointers, then you are screwed. :(
To clear from the current position to the end of the current line, do this:
public static void ClearToEndOfCurrentLine()
{
int currentLeft = Console.CursorLeft;
int currentTop = Console.CursorTop;
Console.Write(new String(' ', Console.WindowWidth - currentLeft));
Console.SetCursorPosition(currentLeft, currentTop);
}
Since you don't want to add a class to cells containing an icon, how about this...
Wrap the contents of each non-icon td
in a span
:
<td><span>consectetur</span></td>
<td><span>adipiscing</span></td>
<td><span>elit</span></td>
And use this CSS:
td {
text-align: center;
}
td span {
text-align: left;
display: block;
}
I wouldn't normally post an answer in this situation, but this seems too long for a comment.
Remember that a multi-dimensional array is like a table. You don't have an x element and a y element for each entry; you have a string at (for instance) table[1,2]
.
So, each entry is still only one string (in your example), it's just an entry at a specific x/y value. So, to get both entries at table[1, x]
, you'd do a nested for loop. Something like the following (not tested, but should be close)
for (int x = 0; x < table.Length; x++)
{
for (int y = 0; y < table.Length; y += 2)
{
Console.WriteLine("{0} {1}", table[x, y], table[x, y + 1]);
}
}
Modern Jest allows you to make more checks on a rejected value. For example:
const request = Promise.reject({statusCode: 404})
await expect(request).rejects.toMatchObject({ statusCode: 500 });
will fail with error
Error: expect(received).rejects.toMatchObject(expected)
- Expected
+ Received
Object {
- "statusCode": 500,
+ "statusCode": 404,
}
Apple keep changing things for no reason: Swift 4+:

thanks apple for wasting people time to figure out what "font size" methods they need to use!
Start by adding a regular matInput to your template. Let's assume you're using the formControl directive from ReactiveFormsModule to track the value of the input.
Reactive forms provide a model-driven approach to handling form inputs whose values change over time. This guide shows you how to create and update a simple form control, progress to using multiple controls in a group, validate form values, and implement more advanced forms.
import { FormsModule, ReactiveFormsModule } from "@angular/forms"; //this to use ngModule
...
imports: [
BrowserModule,
AppRoutingModule,
HttpModule,
FormsModule,
RouterModule,
ReactiveFormsModule,
BrowserAnimationsModule,
MaterialModule],
To open the Eye Dropper simply:
Its main functionality is to inspect pixel color values by clicking them though with its new features you can also see your page's existing colors palette or material design palette by clicking on the two arrows icon at the bottom. It can get quite handy when designing your page.
You can use git add -i
to get an interactive version of git add
, although that's not exactly what you're after. The simplest thing to do is, after having git add
ed, use git status
to see what is staged or not.
Using git add .
isn't really recommended unless it's your first commit. It's usually better to explicitly list the files you want staged, so that you don't start tracking unwanted files accidentally (temp files and such).
try below:
var temp_datetime_obj = new Date();
collection.find({
start_date:{
$gte: new Date(temp_datetime_obj.toISOString())
}
}).toArray(function(err, items) {
/* you can console.log here */
});
Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.
You should read Working with Auto Layout Programmatically and Visual Format Language.
You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.
You might be using a windows or linux computer where you have not logged into git hub so the certificate is not verified. From the sytem where you are getting error login to github with the credential then try to use the command it will work . Good Luck

You may also find pprint helpful.
You're right: String is a subset of Object. Since String is more "precise" than Object, you should cast it to use it as an argument for System.out.println().
Why use a regex?
name.contains(" ")
That should work just as well, and be faster.
@eakssjo's benchmark is broken - measures creating hashes in loop vs creating regexes in loop. Fixed version (plus I've added List::Util::first
and List::MoreUtils::any
):
use List::Util qw(first);
use List::MoreUtils qw(any);
use Benchmark;
my @list = ( 1..10_000 );
my $hit = 5_000;
my $hit_regex = qr/^$hit$/; # precompute regex
my %params;
$params{$_} = 1 for @list; # precompute hash
timethese(
100_000, {
'any' => sub {
die unless ( any { $hit_regex } @list );
},
'first' => sub {
die unless ( first { $hit_regex } @list );
},
'grep' => sub {
die unless ( grep { $hit_regex } @list );
},
'hash' => sub {
die unless ( $params{$hit} );
},
});
And result (it's for 100_000 iterations, ten times more than in @eakssjo's answer):
Benchmark: timing 100000 iterations of any, first, grep, hash...
any: 0 wallclock secs ( 0.67 usr + 0.00 sys = 0.67 CPU) @ 149253.73/s (n=100000)
first: 1 wallclock secs ( 0.63 usr + 0.01 sys = 0.64 CPU) @ 156250.00/s (n=100000)
grep: 42 wallclock secs (41.95 usr + 0.08 sys = 42.03 CPU) @ 2379.25/s (n=100000)
hash: 0 wallclock secs ( 0.01 usr + 0.00 sys = 0.01 CPU) @ 10000000.00/s (n=100000)
(warning: too few iterations for a reliable count)
Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.
If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.
Use cut
:
cut -c6-
This prints each line of the input starting at column 6 (the first column is 1).
An example of Python's way of doing "ternary" expressions:
i = 5 if a > 7 else 0
translates into
if a > 7:
i = 5
else:
i = 0
This actually comes in handy when using list comprehensions, or sometimes in return statements, otherwise I'm not sure it helps that much in creating readable code.
The readability issue was discussed at length in this recent SO question better way than using if-else statement in python.
It also contains various other clever (and somewhat obfuscated) ways to accomplish the same task. It's worth a read just based on those posts.
This is another method I use because changing DropDownSyle
to DropDownList
makes it look 3D and sometimes its just plain ugly.
You can prevent user input by handling the KeyPress

You want to ask is "what is the difference between a mutable and a non-mutable array or dictionary." Many times there different terms are used to describe things that you already know about. In this case, you can replace the term "mutable" with "dynamic." So, a mutuable dictionary or array is one that is "dynamic" and can change at runtime, whereas a non-mutable dictionary or array is one that is "static" and defined in your code and does not change at runtime (in other words, you will not be adding, deleting or possibly sorting the elements.)
As to how it is done, you are asking us to repeat the documentation here. All you need to do is to search in sample code and the Xcode documentation to see exactly how it is done. But the mutable thing threw me too when I was first learning, so I'll give you that one!

There's an ipython notebook with all this code here. I've learned a lot from 'overflow so hopefully someone will find this useful.
I would strongly suggest you to read through the docs, for similar methods. If you are interested in context path, have a look here, ServletContext.getContextPath().
The pure Groovy solutions that read the global env
variable don't print all environment variables (e. g. they are missing variables from the environment
block, from withEnv
context and most of the machine-specific variables from the OS). Using shell steps it is possible to get a more complete set, but that requires a node
context, which is not always wanted.
Here is a solution that uses the getContext
step to retrieve and print the complete set of environment variables, including pipeline parameters, for the current context.
Caveat: Doesn't work in Groovy sandbox. You can use it from a trusted shared library though.
def envAll = getContext( hudson.EnvVars )
echo envAll.collect{ k, v -> "$k = $v" }.join('\n')
Changing this project setting solve the issue for me.
There are two ways to add one dictionary to another.
Update (modifies orig
in place)
orig.update(extra) # Python 2.7+
orig |= extra # Python 3.9+
Merge (creates a new dictionary)
# Python 2.7+
dest = collections.ChainMap(orig, extra)
dest = {k: v for d in (orig, extra) for (k, v) in d.items()}
# Python 3
dest = {**orig, **extra}
dest = {**orig, 'D': 4, 'E': 5}
# Python 3.9+
dest = orig | extra
Note that these operations are noncommutative. In all cases, the latter is the winner. E.g.
orig = {'A': 1, 'B': 2} extra = {'A': 3, 'C': 3} dest = orig | extra # dest = {'A': 3, 'B': 2, 'C': 3} dest = extra | orig # dest = {'A': 1, 'B': 2, 'C': 3}
It is also important to note that only from Python 3.7 (and CPython 3.6)
dict
s are ordered. So, in previous versions, the order of the items in the dictionary may vary.

LD_LIBRARY_PATH
is the default library path which is accessed to check for available dynamic and shared libraries. It is specific to linux distributions.
It is similar to environment variable PATH
in windows that linker checks for possible implementations during linking time.
Here's the Java code using registerDefaultNetworkCallback
(and registerNetworkCallback
for API < 24):
ConnectivityManager.NetworkCallback networkCallback = new ConnectivityManager.NetworkCallback() {
@Override
public void onAvailable(Network network) {
// network available
}
@Override
public void onLost(Network network) {
// network unavailable
}
};
ConnectivityManager connectivityManager =
(ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
connectivityManager.registerDefaultNetworkCallback(networkCallback);
} else {
NetworkRequest request = new NetworkRequest.Builder()
.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET).build();
connectivityManager.registerNetworkCallback(request, networkCallback);
}
Here is C code to check if two points are on the opposite sides of the line segment. Using this code you can check if two segments intersect as well.
// true if points p1, p2 lie on the opposite sides of segment s1--s2
bool oppositeSide (Point2f s1, Point2f s2, Point2f p1, Point2f p2) {
//calculate normal to the segment
Point2f vec = s1-s2;
Point2f normal(vec.y, -vec.x); // no need to normalize
// vectors to the points
Point2f v1 = p1-s1;
Point2f v2 = p2-s1;
// compare signs of the projections of v1, v2 onto the normal
float proj1 = v1.dot(normal);
float proj2 = v2.dot(normal);
if (proj1==0 || proj2==0)
cout<<"collinear points"<<endl;
return(SIGN(proj1) != SIGN(proj2));
}
If you are using your EditText in Dialog or creating dynamically and You can't set it from xml then this example will help you in setting that type of key board while you are using dynamic Edit Text etc
myEditTxt.setInputType(InputType.TYPE_CLASS_NUMBER);
where myEditTxt is the dynamic EDIT TEXT object(name)
ListenForClients
is getting invoked twice (on two different threads) - once from the constructor, once from the explicit method call in Main
. When two instances of the TcpListener
try to listen on the same port, you get that error.
1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib
Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.Place the following after the setContentView() method.
final EditText edit = (EditText) findViewById(R.id.Your_Edit_ID);
String emailString = (String) edit.getText().toString();
Log.d("email",emailString);
Here is using just one command without cURL. Super simple.
echo file_get_contents('https://www.server.com', false, stream_context_create([
'http' => [
'method' => 'POST',
'header' => "Content-type: application/x-www-form-urlencoded",
'content' => http_build_query([
'key1' => 'Hello world!', 'key2' => 'second value'
])
]
]));
For the sake of completeness, here's another possible solution:
SELECT sensorID,timestamp,sensorField1,sensorField2
FROM sensorTable s1
WHERE timestamp = (SELECT MAX(timestamp) FROM sensorTable s2 WHERE s1.sensorID = s2.sensorID)
ORDER BY sensorID, timestamp;
Pretty self-explaining I think, but here's more info if you wish, as well as other examples. It's from the MySQL manual, but above query works with every RDBMS (implementing the sql'92 standard).
I know this is an older post but it may be useful for those who are looking to show a .NET server side image using jQuery.
You have to use a slightly different logic.
So, $("#<%=myServerimg.ClientID%>").show() will not work if you hid the image using myServerimg.visible = false.
Instead, use the following on server side:
myServerimg.Style.Add("display", "none")
Here is a way that removes the lines containing "YOURTEXT" completely:
.*YOURTEXT.*[\r]?[\n]
(replace YOURTEXT with your text)The given regular expression matches both Windows and Unix end of lines.
If your text contains characters that have a special meaning for regular expression, like the backslash, you will need to escape them.
Check the errorlevel
in an if
statement, and then exit /b
(exit the batch file only, not the entire cmd.exe process) for values other than 0.
same-executable-over-and-over.exe /with different "parameters"
if %errorlevel% neq 0 exit /b %errorlevel%
If you want the value of the errorlevel to propagate outside of your batch file
if %errorlevel% neq 0 exit /b %errorlevel%
but if this is inside a for
it gets a bit tricky. You'll need something more like:
setlocal enabledelayedexpansion
for %%f in (C:\Windows\*) do (
same-executable-over-and-over.exe /with different "parameters"
if !errorlevel! neq 0 exit /b !errorlevel!
)
Edit: You have to check the error after each command. There's no global "on error goto" type of construct in cmd.exe/command.com batch. I've also updated my code per CodeMonkey, although I've never encountered a negative errorlevel in any of my batch-hacking on XP or Vista.
You can use Pandas library to read the first few lines from the huge dataset.
import pandas as pd
data = pd.read_csv("names.csv", nrows=1)
You can mention the number of lines to be read in the nrows parameter.
I did a modify with the Visual Studio from Control Panel, Programs and Features. The SDK was not at first apparent so I installed the Common Tools which lo and behold did include the SDK Update 3.
The <Leader>
key is mapped to \ by default. So if you have a map of <Leader>t
, you can execute it by default with \+t. For more detail or re-assigning it using the mapleader
variable, see
:help leader
To define a mapping which uses the "mapleader" variable, the special string "<Leader>" can be used. It is replaced with the string value of "mapleader". If "mapleader" is not set or empty, a backslash is used instead. Example: :map <Leader>A oanother line <Esc> Works like: :map \A oanother line <Esc> But after: :let mapleader = "," It works like: :map ,A oanother line <Esc> Note that the value of "mapleader" is used at the moment the mapping is defined. Changing "mapleader" after that has no effect for already defined mappings.
I think the correct answer should be java.sql.Timestamp is NOT timezone specific. Timestamp is a composite of java.util.Date and a separate nanoseconds value. There is no timezone information in this class. Thus just as Date this class simply holds the number of milliseconds since January 1, 1970, 00:00:00 GMT + nanos.
In PreparedStatement.setTimestamp(int parameterIndex, Timestamp x, Calendar cal) Calendar is used by the driver to change the default timezone. But Timestamp still holds milliseconds in GMT.
API is unclear about how exactly JDBC driver is supposed to use Calendar. Providers seem to feel free about how to interpret it, e.g. last time I worked with MySQL 5.5 Calendar the driver simply ignored Calendar in both PreparedStatement.setTimestamp and ResultSet.getTimestamp.
Make use of the very convenient and free interactive location simulator for Android phones and tablets (named CATLES). It mocks the GPS-location on a system-wide level (even within the Google Maps or Facebook apps) and it works on physical as well as virtual devices:
You can run this command for making a factory reset:
killall dropbear uhttpd; sleep 1; mtd -r erase rootfs_data
This function allows you to create a directory on the user home directory.
private static void createDirectory(final String directoryName) {
final File homeDirectory = new File(System.getProperty("user.home"));
final File newDirectory = new File(homeDirectory, directoryName);
if(!newDirectory.exists()) {
boolean result = newDirectory.mkdir();
if(result) {
System.out.println("The directory is created !");
}
} else {
System.out.println("The directory already exist");
}
}
Strings in C# already have a char indexer
string test = "this is a test";
Console.WriteLine(test[0]);
And...
if(test[0] == 't')
Console.WriteLine("The first letter is 't'");
This works too...
Console.WriteLine("this is a test"[0]);
And this...
foreach (char c in "this is a test")
Console.WriteLine(c);
EDIT:
I noticed the question was updated with regards to char[] arrays. If you must have a string[] array, here's how you split a string at each character in c#:
string[] test = Regex.Split("this is a test", string.Empty);
foreach (string s in test)
{
Console.WriteLine(s);
}
The limitations of a 32-bit JVM on a 64-bit OS will be exactly the same as the limitations of a 32-bit JVM on a 32-bit OS. After all, the 32-bit JVM will be running In a 32-bit virtual machine (in the virtualization sense) so it won't know that it's running on a 64-bit OS/machine.
The one advantage to running a 32-bit JVM on a 64-bit OS versus a 32-bit OS is that you can have more physical memory, and therefore will encounter swapping/paging less frequently. This advantage is only really fully realized when you have multiple processes, however.
Maybe you can try this:
void foo(const char* str)
{
// Do something
}
foo("Hello")
It works for me
I know this is an old thread, but if anyone is looking for an answer of why their procedures doesn't work in the workbench and think the only result is "Query canceled" or anything like that without clues:
the output with errors or problems is hiddenl. I do not know why, I do understand it's annoying, but it is there. just move your cursor above the line above the message, it will turn in an double arrow (up and down) you can then click and drag that line up, then you will see a console with the message you missed!
When you think "check to see if a in b", think hashes (in this case, sets). The fastest way is to hash the list you want to check, and then check each item in there.
This is why Joe Koberg's answer is fast: checking set intersection is very fast.
When you don't have a lot of data though, making sets can be a waste of time. So, you can make a set of the list and just check each item:
tocheck = [1,2] # items to check
a = [2,3,4] # the list
a = set(a) # convert to set (O(len(a)))
print [i for i in tocheck if i in a] # check items (O(len(tocheck)))
When the number of items you want to check is small, the difference can be negligible. But check lots of numbers against a large list...
tests:
from timeit import timeit
methods = ['''tocheck = [1,2] # items to check
a = [2,3,4] # the list
a = set(a) # convert to set (O(n))
[i for i in tocheck if i in a] # check items (O(m))''',
'''L1 = [2,3,4]
L2 = [1,2]
[i for i in L1 if i in L2]''',
'''S1 = set([2,3,4])
S2 = set([1,2])
S1.intersection(S2)''',
'''a = [1,2]
b = [2,3,4]
any(x in a for x in b)''']
for method in methods:
print timeit(method, number=10000)
print
methods = ['''tocheck = range(200,300) # items to check
a = range(2, 10000) # the list
a = set(a) # convert to set (O(n))
[i for i in tocheck if i in a] # check items (O(m))''',
'''L1 = range(2, 10000)
L2 = range(200,300)
[i for i in L1 if i in L2]''',
'''S1 = set(range(2, 10000))
S2 = set(range(200,300))
S1.intersection(S2)''',
'''a = range(200,300)
b = range(2, 10000)
any(x in a for x in b)''']
for method in methods:
print timeit(method, number=1000)
speeds:
M1: 0.0170331001282 # make one set
M2: 0.0164539813995 # list comprehension
M3: 0.0286040306091 # set intersection
M4: 0.0305438041687 # any

M3: 0.466138124466 # set intersection
M4: 0.668627977371 # any
The method that is consistently fast is to make one set (of the list), but the intersection works on large data sets the best!
Assuming you have a test.json
file with the following content:
{"67790": {"1": {"kwh": 319.4}}}
Then, the code below will load
the json file, update the data inside using dict.update()
and dump
into the test.json
file:
import json
a_dict = {'new_key': 'new_value'}
with open('test.json') as f:
data = json.load(f)
data.update(a_dict)
with open('test.json', 'w') as f:
json.dump(data, f)
Then, in test.json
, you'll have:
{"new_key": "new_value", "67790": {"1": {"kwh": 319.4}}}
Hope this is what you wanted.
If you are not root user then, use following commands:
There are two ways to do it -
1.
sudo vi path_to_file/file_name
Press Esc and then type below respectively
:wq //save and exit :q! //exit without saving
When using nano: after you finish editing press ctrl+x then it will ask save Y/N.
If you want to save press Y, if not press N. And press enter to exit the editor.
This post is just to mention an additional option. In case you need to set custom R libs in your Linux shell script you may easily do so by
export R_LIBS="~/R/lib"
See R admin guide on complete list of options.
First you create a MySQL table to store images, like for example:
create table testblob (
image_id tinyint(3) not null default '0',
image_type varchar(25) not null default '',
image blob not null,
image_size varchar(25) not null default '',
image_ctgy varchar(25) not null default '',
image_name varchar(50) not null default ''
);
Then you can write an image to the database like:
/***
* All of the below MySQL_ commands can be easily
* translated to MySQLi_ with the additions as commented
***/
$imgData = file_get_contents($filename);
$size = getimagesize($filename);
mysql_connect("localhost", "$username", "$password");
mysql_select_db ("$dbname");
// mysqli
// $link = mysqli_connect("localhost", $username, $password,$dbname);
$sql = sprintf("INSERT INTO testblob
(image_type, image, image_size, image_name)
VALUES
('%s', '%s', '%d', '%s')",
/***
* For all mysqli_ functions below, the syntax is:
* mysqli_whartever($link, $functionContents);
***/
mysql_real_escape_string($size['mime']),
mysql_real_escape_string($imgData),
$size[3],
mysql_real_escape_string($_FILES['userfile']['name'])
);
mysql_query($sql);
You can display an image from the database in a web page with:
$link = mysql_connect("localhost", "username", "password");
mysql_select_db("testblob");
$sql = "SELECT image FROM testblob WHERE image_id=0";
$result = mysql_query("$sql");
header("Content-type: image/jpeg");
echo mysql_result($result, 0);
mysql_close($link);
Add a class:
.com_box:after {
content: '';
position: absolute;
left: 18px;
top: 50px;
width: 0;
height: 0;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-top: 20px solid #000;
clear: both;
}
Updated your jsfiddle: http://jsfiddle.net/wrm4y8k6/8/
If you are using select as inline to other component, then you can also use like given below.
<select onChange={(val) => this.handlePeriodChange(val.target.value)} className="btn btn-sm btn-outline-secondary dropdown-toggle">
<option value="TODAY">Today</option>
<option value="THIS_WEEK" >This Week</option>
<option value="THIS_MONTH">This Month</option>
<option value="THIS_YEAR">This Year</option>
<option selected value="LAST_AVAILABLE_DAY">Last Availabe NAV Day</option>
</select>
And on the component where select is used, define the function to handle onChange like below:
handlePeriodChange(selVal) {
this.props.handlePeriodChange(selVal);
}
If you decorate the User
class with the XmlType
to match the required capitalization:
[XmlType("user")]
public class User
{
...
}
Then the XmlRootAttribute
on the XmlSerializer
ctor can provide the desired root and allow direct reading into List<>:
// e.g. my test to create a file
using (var writer = new FileStream("users.xml", FileMode.Create))
{
XmlSerializer ser = new XmlSerializer(typeof(List<User>),
new XmlRootAttribute("user_list"));
List<User> list = new List<User>();
list.Add(new User { Id = 1, Name = "Joe" });
list.Add(new User { Id = 2, Name = "John" });
list.Add(new User { Id = 3, Name = "June" });
ser.Serialize(writer, list);
}
...
// read file
List<User> users;
using (var reader = new StreamReader("users.xml"))
{
XmlSerializer deserializer = new XmlSerializer(typeof(List<User>),
new XmlRootAttribute("user_list"));
users = (List<User>)deserializer.Deserialize(reader);
}
This should work:
git show branch:file
Where branch can be any ref (branch, tag, HEAD, ...) and file is the full path of the file. To export it you could use
git show branch:file > exported_file
You should also look at VonC's answers to some related questions:
UPDATE 2015-01-19:
Nowadays you can use relative paths with git show a1b35:./file.txt
.
Simply check it by calling post method on your layout or view
view.post( new Runnable() {
@Override
public void run() {
// your layout is now drawn completely , use it here.
}
});
As declaration of array list in java is like
public class ArrayList<E> extends AbstractList<E> implements List<E>, RandomAccess, Cloneable, Serializable
There is numerous way you can create and initialize array list in java.
1) List list = new ArrayList();
2) List<type> myList = new ArrayList<>();
3) List<type> myList = new ArrayList<type>();
4) Using Utility class
List<Integer> list = Arrays.asList(8, 4);
Collections.unmodifiableList(Arrays.asList("a", "b", "c"));
5) Using static factory method
List<Integer> immutableList = List.of(1, 2);
6) Creation and initializing at a time
List<String> fixedSizeList = Arrays.asList(new String[] {"Male", "Female"});
Again you can create different types of list. All has their own characteristics
List a = new ArrayList();
List b = new LinkedList();
List c = new Vector();
List d = new Stack();
List e = new CopyOnWriteArrayList();
Well in JavaScript you can check two strings for values same as integers so yo can do this:
"A" < "B"
"A" == "B"
"A" > "B"
And therefore you can make your own function that checks strings the same way as the strcmp()
.
So this would be the function that does the same:
function strcmp(a, b)
{
return (a<b?-1:(a>b?1:0));
}
ls -lR
is what you were looking for, or atleast I was. cheers

For this issue need to add the partition for date column values, If last partition 20201231245959, then inserting the 20210110245959 values, this issue will occurs.
For that need to add the 2021 partition into that table
ALTER TABLE TABLE_NAME ADD PARTITION PARTITION_NAME VALUES LESS THAN (TO_DATE('2021-12-31 24:59:59', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')) NOCOMPRESS
You can also set the title of your chart by adding the title parameter as follows
ax.set(xlabel='common xlabel', ylabel='common ylabel', title='some title')
As a fallback solution, you could wrap your classes in a parent element like this:
<div>
<div>This text should appear as normal</div>
<p>This text should be blue.</p>
<div>
<!-- first-child / first-of-type starts from here -->
<p class="myclass1">This text should appear red.</p>
<p class="myclass2">This text should appear green.</p>
</div>
</div>
You can use the :last-of-type
pseudo-class:
tr > td:last-of-type {
/* styling here */
}

Check out the W3C CSS guidelines for more info.
I ran into the exact same problem under identical circumstances. I don't have the tnsnames.ora file, and I wanted to use SQL*Plus with Easy Connection Identifier format in command line. I solved this problem as follows.
The SQL*Plus® User's Guide and Reference gives an example:
sqlplus hr@\"sales-server:1521/sales.us.acme.com\"
Pay attention to two important points:
I found these good questions to detect service name via existing connection: 1, 2. Try this query for example:
SELECT value FROM V$SYSTEM_PARAMETER WHERE UPPER(name) = 'SERVICE_NAMES'
Selenium WebDriver C# code for selecting item from Drop Down:
IWebElement EducationDropDownElement = driver.FindElement(By.Name("education"));
SelectElement SelectAnEducation = new SelectElement(EducationDropDownElement);
There are 3 ways to select drop down item: i)Select by Text ii) Select by Index iii) Select by Value
Select by Text:
SelectAnEducation.SelectByText("College");//There are 3 items - Jr.High, HighSchool, College
Select by Index:
SelectAnEducation.SelectByIndex(2);//Index starts from 0. so, 0 = Jr.High 1 = HighSchool 2 = College
Select by Value:
SelectAnEducation.SelectByValue("College");//There are 3 values - Jr.High, HighSchool, College
For full numbers (non-floats) in Angular you can use:
if (Number.isInteger(yourVariable)) {
...
}
In PrimeFaces 3.0, that style get applied on the generated inner <div>
of the table cell, not on the <td>
as you (and I) would expect. The following example should work out for you:
<p:dataTable styleClass="myTable">
with
.myTable td:nth-child(1) {
width: 20px;
}
In PrimeFaces 3.5 and above, it should work exactly the way you coded and expected.
Precision of a number is the number of digits.
Scale of a number is the number of digits after the decimal point.
What is generally implied when setting precision and scale on field definition is that they represent maximum values.
Example, a decimal field defined with precision=5
and scale=2
would allow the following values:
123.45
(p=5,s=2)12.34
(p=4,s=2)12345
(p=5,s=0)123.4
(p=4,s=1)0
(p=0,s=0)The following values are not allowed or would cause a data loss:
12.345
(p=5,s=3) => could be truncated into 12.35
(p=4,s=2)1234.56
(p=6,s=2) => could be truncated into 1234.6
(p=5,s=1)123.456
(p=6,s=3) => could be truncated into 123.46
(p=5,s=2)123450
(p=6,s=0) => out of rangeNote that the range is generally defined by the precision: |value| < 10^p
...
I don't know if my answer would make sense to many, but I too faced the same issue and the solution was outrageously simple. All I had to do was to open the program which I used to run the code as an administrator. (right-click --> Run as Administrator).
That was all.
This function does the trick. It's an adaptation of this, fairly longer implementation this repo ..
const color = (str) => {
let rgb = [];
// Changing non-hexadecimal characters to 0
str = [...str].map(c => (/[0-9A-Fa-f]/g.test(c)) ? c : 0).join('');
// Padding string with zeroes until it adds up to 3
while (str.length % 3) str += '0';
// Dividing string into 3 equally large arrays
for (i = 0; i < str.length; i += str.length / 3)
rgb.push(str.slice(i, i + str.length / 3));
// Formatting a hex color from the first two letters of each portion
return `#${rgb.map(string => string.slice(0, 2)).join('')}`;
}
You can read here about the behaviour of attributes in many different browsers, including IE.
element.setAttribute()
should do the trick, even in IE. Did you try it? If it doesn't work, then maybe
element.attributeName = 'value'
might work.
Same as AMIB answer, for soft delete error "Unknown column 'table_alias.deleted_at'",
just add ->withTrashed()
then handle it yourself like ->whereRaw('items_alias.deleted_at IS NULL')
You can change the row height of the Datagridview in the
.cs [Design]
.
Then click the datagridview Properties
.
Look for RowTemplate
and expand it,
then type the value in the Height
.

Want to format it automatically when you save the file???
then Goto Window > Preferences > Java > Editor > Save Actions
and configure your save actions.
Along with saving, you can format, Organize imports,add modifier ‘final’ where possible etc
The explanation from Scott Meyers in Effective C++ might help understand when to use them:
Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.

I just tried some of the suggestions here and while I was able to use the browser back button, when I clicked on a menu selection the [Authorize] token for that [ActionResult] sent me right back to the login screen.
Here is my logout code:
FormsAuthentication.SignOut();
Response.Cookies.Remove(FormsAuthentication.FormsCookieName);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
HttpCookie cookie = HttpContext.Request.Cookies[FormsAuthentication.FormsCookieName];
if (cookie != null)
{
cookie.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Add(cookie);
}
Although the back function on the browser took me back and displayed the secured menu (I am still working on that) I was not able to do anything that was secured in the app.
Hope this helps
Try:
chcp 65001
which will change the code page to UTF-8. Also, you need to use Lucida console fonts.
Not gonna happen with CSS only
Inline javascript
<a href='index.html'
onmouseover='this.style.textDecoration="none"'
onmouseout='this.style.textDecoration="underline"'>
Click Me
</a>
In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:
<a href="http://www.w3.org/Style/CSS"
style="{color: blue; background: white} /* a+=0 b+=0 c+=0 */
:visited {color: green} /* a+=0 b+=1 c+=0 */
:hover {background: yellow} /* a+=0 b+=1 c+=0 */
:visited:hover {color: purple} /* a+=0 b+=2 c+=0 */
">

but it was never implemented in the release of the spec as far as I know.

Probably an evolution, it appears that inline css filters works nicely on elements, in a certain way.
Declaring a drop-shadow css filter, in an svg element, in both a class or inline does NOT works, as specified earlier.
But, at least in Firefox, with the following wizardry:
Appending the filter declaration inline, with javascript, after DOM load.
// Does not works, with regular dynamic css styling:
shadow0.oninput = () => {
rect1.style.filter = "filter:drop-shadow(0 0 " + shadow0.value + "rem black);"
}
// Okay! Inline styling, appending.
shadow1.oninput = () => {
rect1.style += " ;filter:drop-shadow(0 0 " + shadow1.value + "rem black);"
rect2.style += " ;filter:drop-shadow(0 0 " + shadow1.value + "rem black);"
}

A soft git reset will put committed changes back into your index. Next, checkout the branch you had intended to commit on. Then git commit with a new commit message.
git reset --soft <commit>
git checkout <branch>
git commit -m "Commit message goes here"
From git docs:
git reset [<mode>] [<commit>]
This form resets the current branch head to and possibly updates the index (resetting it to the tree of ) and the working tree depending on . If is omitted, defaults to --mixed. The must be one of the following:
--soft
Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.
According to the documentation:
$validator = Validator::make($request->all(), [
'file' => 'max:500000',
]);
The value is in kilobytes. I.e. max:10240
= max 10 MB.
This will do the trick :-
new Date().valueOf()
You can execute your task in a different thread. threading.Timer
will let you execute a given callback once after some time has elapsed, if you want to execute your task, for example, as long as the callback returns True
(this is actually what glib.timeout_add
provides, but you might not have it installed in windows) or until you cancel it, you can use this code:
import logging, threading, functools
import time
logging.basicConfig(level=logging.NOTSET,
format='%(threadName)s %(message)s')
class PeriodicTimer(object):
def __init__(self, interval, callback):
self.interval = interval
@functools.wraps(callback)
def wrapper(*args, **kwargs):
result = callback(*args, **kwargs)
if result:
self.thread = threading.Timer(self.interval,
self.callback)
self.thread.start()
self.callback = wrapper
def start(self):
self.thread = threading.Timer(self.interval, self.callback)
self.thread.start()
def cancel(self):
self.thread.cancel()
def foo():
logging.info('Doing some work...')
return True
timer = PeriodicTimer(1, foo)
timer.start()
for i in range(2):
time.sleep(2)
logging.info('Doing some other work...')
timer.cancel()
Example output:
Thread-1 Doing some work...
Thread-2 Doing some work...
MainThread Doing some other work...
Thread-3 Doing some work...
Thread-4 Doing some work...
MainThread Doing some other work...
Note: The callback isn't executed every interval execution. Interval is the time the thread waits between the callback finished the last time and the next time is called.
Since there can be multiple columns with same name , we should first rename the columns. Here is code for the solution.
df.columns=list(range(0,len(df.columns)))
df.drop(columns=[1,2])#drop second and third columns
In order to get the group chat id, do as follows:

This is about as efficient as it gets. The important part only gets executed every 15 seconds and the script sleeps the rest of the time (thus not wasting cycles).
Two example works for me, for your reference.

Typically you would always put the hyphen first in the []
match section. EG, to match any alphanumeric character including hyphens (written the long way), you would use [-a-zA-Z0-9]
Most of these answers work only for a simple case when you are not sending attachment. In my case I need sometimes to send attachment (ACTION_SEND) or two attachments (ACTION_SEND_MULTIPLE).
So I took best approaches from this thread and combined them. It's using support library's ShareCompat.IntentBuilder
but I show only apps which match the ACTION_SENDTO with "mailto:" uri. This way I get only list of email apps with attachment support:
fun Activity.sendEmail(recipients: List<String>, subject: String, file: Uri, text: String? = null, secondFile: Uri? = null) {
val originalIntent = createEmailShareIntent(recipients, subject, file, text, secondFile)
val emailFilterIntent = Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"))
val originalIntentResults = packageManager.queryIntentActivities(originalIntent, 0)
val emailFilterIntentResults = packageManager.queryIntentActivities(emailFilterIntent, 0)
val targetedIntents = originalIntentResults
.filter { originalResult -> emailFilterIntentResults.any { originalResult.activityInfo.packageName == it.activityInfo.packageName } }
.map {
createEmailShareIntent(recipients, subject, file, text, secondFile).apply { `package` = it.activityInfo.packageName }
}
.toMutableList()
val finalIntent = Intent.createChooser(targetedIntents.removeAt(0), R.string.choose_email_app.toText())
finalIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toTypedArray())
startActivity(finalIntent)
}
private fun Activity.createEmailShareIntent(recipients: List<String>, subject: String, file: Uri, text: String? = null, secondFile: Uri? = null): Intent {
val builder = ShareCompat.IntentBuilder.from(this)
.setType("message/rfc822")
.setEmailTo(recipients.toTypedArray())
.setStream(file)
.setSubject(subject)
if (secondFile != null) {
builder.addStream(secondFile)
}
if (text != null) {
builder.setText(text)
}
return builder.intent
}
Sometimes your Xcode project file gets messed up, especially if you have an old project and first created it with an older version of Xcode/iPhone SDK.
What you need to do is open up the project file in a text editor, search for the 'long string' from your error and manually erase that line.
In fact, you should just go ahead and erase any line that points to any provisioning profiles. Then reopen the project in Xcode, go to the settings and reselect your new profile. This clears up issues like that most of the time.
The lines that point to the provisioning profiles will look like this:
PROVISIONING_PROFILE = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";
"PROVISIONING_PROFILE[sdk=iphoneos*]" = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";
SJLJ (setjmp/longjmp): – available for 32 bit and 64 bit – not “zero-cost”: even if an exception isn’t thrown, it incurs a minor performance penalty (~15% in exception heavy code) – allows exceptions to traverse through e.g. windows callbacks
DWARF (DW2, dwarf-2) – available for 32 bit only – no permanent runtime overhead – needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown over e.g. Windows system DLLs.
SEH (zero overhead exception) – will be available for 64-bit GCC 4.8.

JObject joResponse = JObject.Parse(response);
JObject ojObject = (JObject)joResponse["response"];
JArray array= (JArray)ojObject ["chats"];
int id = Convert.ToInt32(array[0].toString());
If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:
sudo mv geckodriver /usr/local/bin
And it should work.
virtualenv --python=/usr/local/bin/python3 <VIRTUAL ENV NAME>
this will add python3
path for your virtual enviroment.
I like jQuery Token input. Actually prefer the UI over some of the other options mentioned above.

Also see: http://railscasts.com/episodes/258-token-fields for an explanation
If (Not IsNull(Me.id.Value)) Then
DoCmd.GoToRecord , , acNext
End If
Hi, you need to put this in form activate, and have an id field named id...
this way it passes until it reaches the one without id (AKA new one)...
You might want to take a look at Icon fonts. http://css-tricks.com/examples/IconFont/
EDIT: I'm using Font-Awesome on my latest project. You can even bootstrap it. Simply put this in your <head>
:
<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.min.css" rel="stylesheet">
<!-- And if you want to support IE7, add this aswell -->
<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome-ie7.min.css" rel="stylesheet">
And then go ahead and add some icon-links like this:
<a class="icon-thumbs-up"></a>
Here's the full cheat sheet
--edit--
Font-Awesome uses different class names in the new version, probably because this makes the CSS files drastically smaller, and to avoid ambiguous css classes. So now you should use:
<a class="fa fa-thumbs-up"></a>
EDIT 2:
Just found out github also uses its own icon font: Octicons It's free to download. They also have some tips on how to create your very own icon fonts.
UICollectionView has changed in iOS 10 introducing some problems to solutions above.
Here is a good guide: https://littlebitesofcocoa.com/241-uicollectionview-cell-pre-fetching
Cells now stay around for a bit after going off-screen. Which means that sometimes we might not be able to get hold of a cell in didDeselectItemAt indexPath
in order to adjust it. It can then show up on screen un-updated and un-recycled. prepareForReuse
does not help this corner case.
The easiest solution is disabling the new scrolling by setting isPrefetchingEnabled
to false. With this, managing the cell's display with
cellForItemAt
didSelect
didDeselect
works as it used to.
However, if you'd rather keep the new smooth scrolling behaviour it's better to use willDisplay
:
func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
let customCell = cell as! CustomCell
if customCell.isSelected {
customCell.select()
} else {
customCell.unselect()
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
//Don't even need to set selection-specific things here as recycled cells will also go through willDisplay
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let cell = collectionView.cellForItem(at: indexPath) as? CustomCell
cell?.select()
}
func collectionView(_ collectionView: UICollectionView, didDeselectItemAt indexPath: IndexPath) {
let cell = collectionView.cellForItem(at: indexPath) as? CustomCell
cell?.unselect() // <----- this can be null here, and the cell can still come back on screen!
}
With the above you control the cell when it's selected, unselected on-screen, recycled, and just re-displayed.
data.frame[row_number, column_number] = new_value
For example, if x
is your data.frame:
x[1, 4] = 5
Honestly, I hate all the solutions I've seen so far, and I'll tell you why: They just don't seem to ever align it right...so here's what I usually do:
I know what pixel values each div and their respective margins hold...so I do the following.
I'll create a wrapper div that has an absolute position and a left value of 50%...so this div now starts in the middle of the screen, and then I subtract half of all the content of the div's width...and I get BEAUTIFULLY scaling content...and I think this works across all browsers, too. Try it for yourself (this example assumes all content on your site is wrapped in a div tag that uses this wrapper class and all content in it is 200px in width):
.wrapper {
position: absolute;
left: 50%;
margin-left: -100px;
}
EDIT: I forgot to add...you may also want to set width: 0px; on this wrapper div for some browsers to not show the scrollbars, and then you may use absolute positioning for all inner divs.
This also works AMAZING for vertically aligning your content as well using top: 50% and margin-top. Cheers!
Here is a Swift 3 version of Sam Wirch's guide to swift posted by William T.
extension UIImage {
static func resizedCroppedImage(image: UIImage, newSize:CGSize) -> UIImage? {
var ratio: CGFloat = 0
var delta: CGFloat = 0
var offset = CGPoint.zero
if image.size.width > image.size.height {
ratio = newSize.width / image.size.width
delta = (ratio * image.size.width) - (ratio * image.size.height)
offset = CGPoint(x: delta / 2, y: 0)
} else {
ratio = newSize.width / image.size.height
delta = (ratio * image.size.height) - (ratio * image.size.width)
offset = CGPoint(x: 0, y: delta / 2)
}
let clipRect = CGRect(x: -offset.x, y: -offset.y, width: (ratio * image.size.width) + delta, height: (ratio * image.size.height) + delta)
UIGraphicsBeginImageContextWithOptions(newSize, true, 0.0)
UIRectClip(clipRect)
image.draw(in: clipRect)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage
}
}
I also tried this answer but was not entirely happy with the result. I kept googling around and finally found a Nuget Package that helped me to manage the result I wanted, anno 2021. I would like to share it with the former developers of Stack Overflow.
I used this Nuget Package Gu.WPF.Geometry found via this Github Repository. All credits for develoment should go to Johan Larsson, the owner of this package.
How I used it? I wanted to have the commands as buttons below the zoombox, as shown here in MachineLayoutControl.xaml
.
<UserControl
x:Class="MyLib.MachineLayoutControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:effects="http://gu.se/Geometry">

<ResourceDictionary Source="Resources/ResourceDictionaries/AllResourceDictionariesCombined.xaml" />
</UserControl.Resources>
<Grid Margin="0">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Border
Grid.Row="0"
Margin="0,0"
Padding="0"
BorderThickness="1"
Style="{StaticResource Border_Head}"
Visibility="Visible">
<effects:Zoombox
x:Name="ImageBox"
IsManipulationEnabled="True"
MaxZoom="10"
MinZoom="0.1"
Visibility="{Binding Zoombox_Visibility}">
<ContentControl Content="{Binding Viewing_Canvas}" />
</effects:Zoombox>
</Border>
<StackPanel
Grid.Column="1"
Margin="10"
HorizontalAlignment="Right"
Orientation="Horizontal">
<Button
Command="effects:ZoomCommands.Increase"
CommandParameter="2.0"
CommandTarget="{Binding ElementName=ImageBox}"
Content="Zoom In"
Style="{StaticResource StyleForResizeButtons}" />
<Button
Command="effects:ZoomCommands.Decrease"
CommandParameter="2.0"
CommandTarget="{Binding ElementName=ImageBox}"
Content="Zoom Out"
Style="{StaticResource StyleForResizeButtons}" />
<Button
Command="effects:ZoomCommands.Uniform"
CommandTarget="{Binding ElementName=ImageBox}"
Content="See Full Machine"
Style="{StaticResource StyleForResizeButtons}" />
<Button
Command="effects:ZoomCommands.UniformToFill"
CommandTarget="{Binding ElementName=ImageBox}"
Content="Zoom To Machine Width"
Style="{StaticResource StyleForResizeButtons}" />
</StackPanel>
</Grid>
</UserControl>
In the underlying Viewmodel, I had the following relevant code:
public Visibility Zoombox_Visibility { get => movZoombox_Visibility; set { movZoombox_Visibility = value; OnPropertyChanged(nameof(Zoombox_Visibility)); } }
public Canvas Viewing_Canvas { get => mdvViewing_Canvas; private set => mdvViewing_Canvas = value; }
Also, I wanted that immediately on loading, the Uniform to Fill Command was executed, this is something that I managed to do in the code-behind MachineLayoutControl.xaml.cs
. You see that I only set the Zoombox to visible if the command is executed, to avoid "flickering" when the usercontrol is loading.
public partial class MachineLayoutControl : UserControl
{
#region Constructors
public MachineLayoutControl()
{
InitializeComponent();
Loaded += MyWindow_Loaded;
}
#endregion Constructors
#region EventHandlers
private void MyWindow_Loaded(object sender, RoutedEventArgs e)
{
Application.Current.Dispatcher.BeginInvoke(
DispatcherPriority.ApplicationIdle,
new Action(() =>
{
ZoomCommands.Uniform.Execute(null, ImageBox);
((MachineLayoutControlViewModel)DataContext).Zoombox_Visibility = Visibility.Visible;
}));
}
#endregion EventHandlers
}
You're doing something wrong (probably too small read buffer). On a machine of undecent age (Athlon 2x1800MP from 2002) that has DMA on disk probably out of whack (6.6M/s is damn slow when doing sequential reads):
Create a 1G file with "random" data:
# dd if=/dev/sdb of=temp.dat bs=1M count=1024
1073741824 bytes (1.1 GB) copied, 161.698 s, 6.6 MB/s
# time sha1sum -b temp.dat
abb88a0081f5db999d0701de2117d2cb21d192a2 *temp.dat
1m5.299s
# time md5sum -b temp.dat
9995e1c1a704f9c1eb6ca11e7ecb7276 *temp.dat
1m58.832s
This is also weird, md5 is consistently slower than sha1 for me (reran several times).
EDIT: You should check out Needle. It does this for you and supports multipart data, and a lot more.
I figured out I was missing a header
var request = require('request');
request.post({
headers: {'content-type' : 'application/x-www-form-urlencoded'},
url: 'http://localhost/test2.php',
body: "mes=heydude"
}, function(error, response, body){
console.log(body);
});
Well, here is one solution I ended up with, but I hope there's a more elegant one...
StringBuilder result = new StringBuilder();
for(int i=0; i<name.length(); i++) {
char tmpChar = name.charAt( i );
if (Character.isLetterOrDigit( tmpChar) || tmpChar == '_' ) {
result.append( tmpChar );
}
}
result
ends up with the desired result...
There's no such thing as a memory leak in Java. Memory leak is a phrase borrowed from C et al. Java deals with memory allocation internally with the help of the GC. There's memory wastefulness (ie. leaving stranded objects), but not memory leak.
If you'd checked the results of stream.Read
, you'd have seen that it hadn't read anything - because you haven't rewound the stream. (You could do this with stream.Position = 0;
.) However, it's easier to just call ToArray
:
settingsString = LocalEncoding.GetString(stream.ToArray());
(You'll need to change the type of stream
from Stream
to MemoryStream
, but that's okay as it's in the same method where you create it.)
Alternatively - and even more simply - just use StringWriter
instead of StreamWriter
. You'll need to create a subclass if you want to use UTF-8 instead of UTF-16, but that's pretty easy. See this answer for an example.
I'm concerned by the way you're just catching Exception
and assuming that it means something harmless, by the way - without even logging anything. Note that using
statements are generally cleaner than writing explicit finally
blocks.
df.filter(df.location.contains('google.com'))
You can use plain SQL in
filter
df.filter("location like '%google.com%'")
or with DataFrame column methods
df.filter(df.location.like('%google.com%'))
If you're using ZLib in your project, then you need to find :
#if 1
in zconf.h and replace(uncomment) it with :
#if HAVE_UNISTD_H /* ...the rest of the line
If it isn't ZLib I guess you should find some alternative way to do this. GL.
