Please let me complete the answer by @LukeH with some sample code, as I have tested it I believe it may be useful for some:
public class Order
{
public string OrderId { get; set; }
public DateTime OrderDate { get; set; }
public int Quantity { get; set; }
public int Total { get; set; }
public Order(string orderId, DateTime orderDate, int quantity, int total)
{
OrderId = orderId;
OrderDate = orderDate;
Quantity = quantity;
Total = total;
}
}
public void SampleDataAndTest()
{
List<Order> objListOrder = new List<Order>();
objListOrder.Add(new Order("tu me paulo ", Convert.ToDateTime("01/06/2016"), 1, 44));
objListOrder.Add(new Order("ante laudabas", Convert.ToDateTime("02/05/2016"), 2, 55));
objListOrder.Add(new Order("ad ordinem ", Convert.ToDateTime("03/04/2016"), 5, 66));
objListOrder.Add(new Order("collocationem ", Convert.ToDateTime("04/03/2016"), 9, 77));
objListOrder.Add(new Order("que rerum ac ", Convert.ToDateTime("05/02/2016"), 10, 65));
objListOrder.Add(new Order("locorum ; cuius", Convert.ToDateTime("06/01/2016"), 1, 343));
Console.WriteLine("Sort the list by date ascending:");
objListOrder.Sort((x, y) => x.OrderDate.CompareTo(y.OrderDate));
foreach (Order o in objListOrder)
Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);
Console.WriteLine("Sort the list by date descending:");
objListOrder.Sort((x, y) => y.OrderDate.CompareTo(x.OrderDate));
foreach (Order o in objListOrder)
Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);
Console.WriteLine("Sort the list by OrderId ascending:");
objListOrder.Sort((x, y) => x.OrderId.CompareTo(y.OrderId));
foreach (Order o in objListOrder)
Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

I am using Debian 8 live off a USB. I was locked out of the system after 10 min of inactivity. The password that was required to log back in to the system for the user was:
login : Debian Live User
password : live
I hope this helps
You could follow a solution similar to "How do I force “git pull” to overwrite local files?":
git fetch --all
git reset --hard origin/abranch
git checkout $branch
That would involve only one fetch.
With Git 2.23+, git checkout
is replaced here with git switch
(presented here) (still experimental).
git switch -f $branch
(with -f
being an alias for --discard-changes
, as noted in Jan's answer)
Proceed even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
See my answer to Stack Overflow question Finish All previous activities.
What you need is to add the Intent.FLAG_CLEAR_TOP
. This flag makes sure that all activities above the targeted activity in the stack are finished and that one is shown.
Another thing that you need is the SINGLE_TOP
flag. With this one you prevent Android from creating a new activity if there is one already created in the stack.
Just be wary that if the activity was already created, the intent with these flags will be delivered in the method called onNewIntent(intent)
(you need to overload it to handle it) in the target activity.
Then in onNewIntent
you have a method called restart or something that will call finish()
and launch a new intent toward itself, or have a repopulate()
method that will set the new data. I prefer the second approach, it is less expensive and you can always extract the
onCreate
logic into a separate method that you can call for populate.
For those wishing to install a small number of packages in conda with pip then using,
sudo $(which pip) install <instert_package_name>
worked for me.
Explainaton
It seems, for me anyway, that which pip
is very reliable for finding the conda env pip path to where you are. However, when using sudo
, this seems to redirect paths or otherwise break this.
Using the $(which pip)
executes this independently of the sudo
or any of the commands and is akin to running /home/<username>/(mini)conda(3)/envs/<env_name>/pip
in Linux. This is because $()
is run separately and the text output added to the outer command.
gossi's extension of David Coallier's method:
Check these two lines:
from = arguments[i];
Object.getOwnPropertyNames(from).forEach(function (name) {
One need to check "from" against null object... If for example merging an object that comes from an Ajax response, previously created on a server, an object property can have a value of "null", and in that case the above code generates an error saying:
"from" is not a valid object
So for example, wrapping the "...Object.getOwnPropertyNames(from).forEach..." function with an "if (from != null) { ... }" will prevent that error occurring.
Make it a background image that is centered.
.wrapper {background:transparent url(yourimage.jpg) no-repeat center center;}
<div class="wrapper">
...input boxes and labels and submit button here
</div>
You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.
You can use angularjs form state form.$submitted
.
Initially form.$submitted
value will be false
and will became true
after successful form submit.
there is a little problem here because the
if (typeof item !== 'string') {
return false
}
will not stop the foreach. So the function will return true even if the array does contain none string values.
This seems to wok for me:
function isStringArray(value: any): value is number[] {
if (Object.prototype.toString.call(value) === '[object Array]') {
if (value.length < 1) {
return false;
} else {
return value.every((d: any) => typeof d === 'string');
}
}
return false;
}

Try this:
void prime_num(long num)
{
// bool isPrime = true;
for (long i = 0; i <= num; i++)
{
bool isPrime = true; // Move initialization to here
for (long j = 2; j < i; j++) // you actually only need to check up to sqrt(i)
{
if (i % j == 0) // you don't need the first condition
{
isPrime = false;
break;
}
}
if (isPrime)
{
Console.WriteLine ( "Prime:" + i );
}
// isPrime = true;

It's not immediately obvious from the documentation why the following does not work:
<span style={font-size: 1.7} class="glyphicon glyphicon-remove-sign"></span>
But when doing it entirely inline:
"em"
class
is className
The correct way looks like this:
<span style={{fontSize: 1.7 + "em"}} className="glyphicon glyphicon-remove-sign"></span>
you can use indexing.. After indexing, if select * from XXXX results should be as per the index, But only result set.. not structrue of Table
First, you need to understand the difference between window
and document
. The window
object is a top level client side object. There is nothing above the window
object. JavaScript is an object orientated language. You start with an object and apply methods to its properties or the properties of its object groups. For example, the document
object is an object of the window
object. To change the document
's background color, you'd set the document
's bgcolor
property.
window.document.bgcolor = "red"
To answer your question, There is no difference in the end result between window
and document
scrollTop
. Both will give the same output.
In general use document
mainly to register events and use window
to do things like scroll
, scrollTop
, and resize
.
I know this thread has been idle for a while, but I just wanted to add my two cents to supplement jariq's comment...
Per manual, you don't necessary want to use -password
option.
Let's say mykey.key
has a password and your want to protect iphone-dev.p12
with another password, this is what you'd use:
pkcs12 -export -inkey mykey.key -in developer_identity.pem -out iphone_dev.p12 -passin pass:password_for_mykey -passout pass:password_for_iphone_dev

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:
var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";
console.log( JSON.stringify(display) );
This will print:
["none","block","none"]
This is how JSON actually serializes array. However what you want to see is something like:
{"0":"none","1":"block","2":"none"}
To get this format you want to serialize object, not array. So let's rewrite above code like this:
var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";
console.log( JSON.stringify(display2) );
This will print in the format you want.
You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

If the file exists and contains data, then it is possible to generate the fieldname
parameter for csv.DictWriter
automatically:
# read header automatically
with open(myFile, "r") as f:
reader = csv.reader(f)
for header in reader:
break
# add row to CSV file
with open(myFile, "a", newline='') as f:
writer = csv.DictWriter(f, fieldnames=header)
writer.writerow(myDict)
About half of the answers here are the same String.hashCode
hash function taken from Java. It dates back to 1981 from Gosling Emacs, is extremely weak, and makes zero sense performance-wise in modern JavaScript. In fact, implementations could be significantly faster by using ES6 Math.imul
, but no one took notice. We can do much better than this, at essentially identical performance.
Here's something I did—cyrb53, a simple but high quality 53-bit hash. It's quite fast, provides very good hash distribution, and has significantly lower collision rates compared to any 32-bit hash.
const cyrb53 = function(str, seed = 0) {
let h1 = 0xdeadbeef ^ seed, h2 = 0x41c6ce57 ^ seed;
for (let i = 0, ch; i < str.length; i++) {
ch = str.charCodeAt(i);
h1 = Math.imul(h1 ^ ch, 2654435761);
h2 = Math.imul(h2 ^ ch, 1597334677);
}
h1 = Math.imul(h1 ^ (h1>>>16), 2246822507) ^ Math.imul(h2 ^ (h2>>>13), 3266489909);
h2 = Math.imul(h2 ^ (h2>>>16), 2246822507) ^ Math.imul(h1 ^ (h1>>>13), 3266489909);
return 4294967296 * (2097151 & h2) + (h1>>>0);
};
It is similar to the well-known MurmurHash/xxHash algorithms, it uses a combination of multiplication and Xorshift to generate the hash, but not as thorough. As a result it's faster than either in JavaScript and significantly simpler to implement. Furthermore, keep in mind this is not a secure algorithm, if privacy/security is a concern, this is not for you.
Like any proper hash, it has an avalanche effect, which basically means small changes in the input have big changes in the output making the resulting hash appear more 'random':
"501c2ba782c97901" = cyrb53("a")
"459eda5bc254d2bf" = cyrb53("b")
"fbce64cc3b748385" = cyrb53("revenge")
"fb1d85148d13f93a" = cyrb53("revenue")
You can also supply a seed for alternate streams of the same input:
"76fee5e6598ccd5c" = cyrb53("revenue", 1)
"1f672e2831253862" = cyrb53("revenue", 2)
"2b10de31708e6ab7" = cyrb53("revenue", 3)
Technically, it is a 64-bit hash, that is, two uncorrelated 32-bit hashes computed in parallel, but JavaScript is limited to 53-bit integers. If convenient, the full 64-bit output can be used by altering the return statement with a hex string or array.
return [h2>>>0, h1>>>0];
// or
return (h2>>>0).toString(16).padStart(8,0)+(h1>>>0).toString(16).padStart(8,0);
Be aware that constructing hex strings drastically slows down batch processing. The array is more efficient, but obviously requires two checks instead of one.
Just for fun, here's the smallest hash I could come up with that's still decent. It's a 32-bit hash in 89 chars with better quality randomness than even FNV or DJB2:
TSH=s=>{for(var i=0,h=9;i<s.length;)h=Math.imul(h^s.charCodeAt(i++),9**9);return h^h>>>9}
Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):
Sub Module for Connecting to MS SQL with Remote Host & Username/Password
Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String
'Setup the connection string for accessing MS SQL database
'Make sure to change:
'1: PASSWORD
'2: USERNAME
'3: REMOTE_IP_ADDRESS
'4: DATABASE
ConnectionString = "Provider=SQLOLEDB.1;Password=PASSWORD;Persist Security Info=True;User ID=USERNAME;Data Source=REMOTE_IP_ADDRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=DATABASE"
'Opens connection to the database
cnn.Open ConnectionString
'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
cnn.CommandTimeout = 900
'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
StrQuery = "SELECT TOP 10 * FROM tbl_table"
'Performs the actual query
rst.Open StrQuery, cnn
'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook
Sheets(1).Range("A2").CopyFromRecordset rst
End Sub
You can use the with_fileglob
loop for this:
- copy:
src: "{{ item }}"
dest: /etc/fooapp/
owner: root
mode: 600
with_fileglob:
- /playbooks/files/fooapp/*
Take a look at FileSaver.js. It provides a handy saveAs
function which takes care of most browser specific quirks.
"UPDATE TableName SET TableField = TableField + 1 WHERE SomeFilterField = @ParameterID"
The length of the segment is not important, thus using a square root is not required and should be avoided since we could lose some precision.
class Point:
def __init__(self, x, y):
self.x = x
self.y = y
class Segment:
def __init__(self, a, b):
self.a = a
self.b = b
def is_between(self, c):
# Check if slope of a to c is the same as a to b ;
# that is, when moving from a.x to c.x, c.y must be proportionally
# increased than it takes to get from a.x to b.x .
# Then, c.x must be between a.x and b.x, and c.y must be between a.y and b.y.
# => c is after a and before b, or the opposite
# that is, the absolute value of cmp(a, b) + cmp(b, c) is either 0 ( 1 + -1 )
# or 1 ( c == a or c == b)
a, b = self.a, self.b
return ((b.x - a.x) * (c.y - a.y) == (c.x - a.x) * (b.y - a.y) and
abs(cmp(a.x, c.x) + cmp(b.x, c.x)) <= 1 and
abs(cmp(a.y, c.y) + cmp(b.y, c.y)) <= 1)
Some random example of usage :
a = Point(0,0)
b = Point(50,100)
c = Point(25,50)
d = Point(0,8)
print Segment(a,b).is_between(c)
print Segment(a,b).is_between(d)

Just to add to the other answers, there are still noteworthy differences here, specifically when dealing with <svg>
elements.
I have used both .childNodes
and .children
and have preferred working with the HTMLCollection
delivered by the .children
getter.
Today however, I ran into issues with IE/Edge failing when using .children
on an <svg>
.
While .children
is supported in IE on basic HTML elements, it isn't supported on document/document fragments, or SVG elements.
For me, I was able to simply grab the needed elements via .childNodes[n]
because I don't have extraneous text nodes to worry about. You may be able to do the same, but as mentioned elsewhere above, don't forget that you may run into unexpected elements.
Hope this is helpful to someone scratching their head trying to figure out why .children
works elsewhere in their js on modern IE and fails on document or SVG elements.
It might be a little late to the discussion but inevitably someone will stumble onto this post like I did. I found the answer I was looking for and thought I'd post my own take on it. The following JSfiddle includes how to layer .PNG's with transparency. Jerska's mention of the transparency attribute for the div's CSS was the solution: http://jsfiddle.net/jyef3fqr/
HTML:
<button id="toggle-box">toggle</button>
<div id="box" style="display:none;" ><img src="x"></div>
<button id="toggle-box2">toggle</button>
<div id="box2" style="display:none;"><img src="xx"></div>
<button id="toggle-box3">toggle</button>
<div id="box3" style="display:none;" ><img src="xxx"></div>
CSS:
#box {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:1;
}
#box2 {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:2;
background-color : transparent;
}
#box3 {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:2;
background-color : transparent;
}
body {background-color:#c0c0c0; }
JS:
$('#toggle-box').click().toggle(function() {
$('#box').animate({ width: 'show' });
}, function() {
$('#box').animate({ width: 'hide' });
});
$('#toggle-box2').click().toggle(function() {
$('#box2').animate({ width: 'show' });
}, function() {
$('#box2').animate({ width: 'hide' });
});
$('#toggle-box3').click().toggle(function() {
$('#box3').animate({ width: 'show' });
}, function() {
$('#box3').animate({ width: 'hide' });
});
And my original inspiration:http://jsfiddle.net/5g1zwLe3/ I also used paint.net for creating the transparent PNG's, or rather the PNG's with transparent BG's.
Many of the answers here involve looping through an object and "manually" (albeit programmatically) creating a parent property that stores the reference to the parent. The two ways of implementing this seem to be...
init
function to loop through at the time the nested object is created, or...Both approaches have the same issue...
How do you maintain parents as the nested object grows/changes??
If I add a new sub-sub-object, how does it get its parent property filled? If you're (1) using an init
function, the initialization is already done and over, so you'd have to (2) pass the object through a function to search for new children and add the appropriate parent property.
Using ES6 Proxy to add parent
whenever an object/sub-object is set
The approach below is to create a handler for a proxy always adds a parent property each time an object is set. I've called this handler the parenter
handler. The parenter
responsibilities are to recognize when an object is being set and then to...
Create a dummy proxy with the appropriate parent
and the parenter
handler
var p = new Proxy({parent: target}, parenter);
Copy in the supplied objects properties-- Because you're setting the proxy properties in this loop the parenter
handler is working recursively; nested objects are given parents at each level
for(key in value){
p[key] = value[key];
}
Set the proxy not the supplied object
return target[prop] = p;
Full code
var parenter = {
set: function(target, prop, value){
if(typeof value === "object"){
var p = new Proxy({parent: target}, parenter);
for(key in value){
p[key] = value[key];
}
return target[prop] = p;
}else{
target[prop] = value;
}
}
}
var root = new Proxy({}, parenter);
// some examples
root.child1 = {
color: "red",
value: 10,
otherObj: {
otherColor: "blue",
otherValue: 20
}
}
// parents exist/behave as expected
console.log(root.child1.color) // "red"
console.log(root.child1.otherObj.parent.color) // "red"
// new children automatically have correct parent
root.child2 = {color: "green", value3: 50};
console.log(root.child2.parent.child1.color) // "red"
// changes are detected throughout
root.child1.color = "yellow"
console.log(root.child2.parent.child1.color) // "yellow"
Notice that all root children always have parent properties, even children that are added later.
As noted in comments above, while still on some UA implementations, readAsBinaryString
method didn't made its way to the specs and should not be used in production.
Instead, use readAsArrayBuffer
and loop through it's buffer
to get back the binary string :
document.querySelector('input').addEventListener('change', function() {_x000D_
_x000D_
var reader = new FileReader();_x000D_
reader.onload = function() {_x000D_
_x000D_
var arrayBuffer = this.result,_x000D_
array = new Uint8Array(arrayBuffer),_x000D_
binaryString = String.fromCharCode.apply(null, array);_x000D_
_x000D_
console.log(binaryString);_x000D_
_x000D_
}_x000D_
reader.readAsArrayBuffer(this.files[0]);_x000D_
_x000D_
}, false);
_x000D_
<input type="file" />_x000D_
<div id="result"></div>
_x000D_
For a more robust way to convert your arrayBuffer in binary string, you can refer to this answer.
Yes, the file API does provide a way to convert your File, in the <input type="file"/>
to a binary string, thanks to the FileReader Object and its method readAsBinaryString
.
[But don't use it in production !]
document.querySelector('input').addEventListener('change', function(){_x000D_
var reader = new FileReader();_x000D_
reader.onload = function(){_x000D_
var binaryString = this.result;_x000D_
document.querySelector('#result').innerHTML = binaryString;_x000D_
}_x000D_
reader.readAsBinaryString(this.files[0]);_x000D_
}, false);
_x000D_
<input type="file"/>_x000D_
<div id="result"></div>
_x000D_
If you want an array buffer, then you can use the readAsArrayBuffer()
method :
document.querySelector('input').addEventListener('change', function(){_x000D_
var reader = new FileReader();_x000D_
reader.onload = function(){_x000D_
var arrayBuffer = this.result;_x000D_
console.log(arrayBuffer);_x000D_
document.querySelector('#result').innerHTML = arrayBuffer + ' '+arrayBuffer.byteLength;_x000D_
}_x000D_
reader.readAsArrayBuffer(this.files[0]);_x000D_
}, false);
_x000D_
<input type="file"/>_x000D_
<div id="result"></div>
_x000D_
One possible reason for the database being locked that I ran into with SQLite is when I tried to access a row that was being written by one app, and read by another at the same time. You may want to set a busy timeout in your SQLite wrapper that will spin and wait for the database to become free (in the original c++ api the function is sqlite3_busy_timeout). I found that 300ms was sufficient in most cases.
But I doubt this is the problem, based on your post. Try other recommendations first.
The commit should be present in your local, check by using git log
.
If the commit is not present then try git fetch
to update the local with the latest remote.
You probably can't. Here's something that comes close. You won't get content to flow around it if there's space below.
http://jsfiddle.net/ThnLk/1289
.stuck {
position: fixed;
top: 10px;
left: 10px;
bottom: 10px;
width: 180px;
overflow-y: scroll;
}
You can do a percentage height as well:
http://jsfiddle.net/ThnLk/1287/
.stuck {
max-height: 100%;
}
In IE11 Windows 7 this worked for me,
background-size: 100% 100%;
You can simply typecast, and it will do the conversion for you, e.g.
var with = (double?) jToken[key] ?? 100;
It will automatically return null
if said key is not present in the object, so there's no need to test for it.
With Groovy, you can leverage Ant to do:

Here is code that will upload multiple images at once, into a specific folder!
The HTML:
<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">
</ul>
The PHP:
<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$name = $_FILES["images"]["name"][$key];
//$ext = pathinfo($name, PATHINFO_EXTENSION);
$name = explode("_", $name);
$imagename='';
foreach($name as $letter){
$imagename .= $letter;
}
move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" . $imagename);
}
}
echo "<h2>Successfully Uploaded Images</h2>";
And finally, the JavaSCript/Ajax:
(function () {
var input = document.getElementById("images"),
formdata = false;
function showUploadedItem (source) {
var list = document.getElementById("image-list"),
li = document.createElement("li"),
img = document.createElement("img");
img.src = source;
li.appendChild(img);
list.appendChild(li);
}
if (window.FormData) {
formdata = new FormData();
document.getElementById("btn").style.display = "none";
}
input.addEventListener("change", function (evt) {
document.getElementById("response").innerHTML = "Uploading . . ."
var i = 0, len = this.files.length, img, reader, file;
for ( ; i < len; i++ ) {
file = this.files[i];
if (!!file.type.match(/image.*/)) {
if ( window.FileReader ) {
reader = new FileReader();
reader.onloadend = function (e) {
showUploadedItem(e.target.result, file.fileName);
};
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("images[]", file);
}
}
}
if (formdata) {
$.ajax({
url: "submit_image.php",
type: "POST",
data: formdata,
processData: false,
contentType: false,
success: function (res) {
document.getElementById("response").innerHTML = res;
}
});
}
}, false);
}());
Hope this helps
I generally prefer defining my own: const double PI = 2*acos(0.0);
because not all implementations provide it for you.
The question of whether this function gets called at runtime or is static'ed out at compile time is usually not an issue, because it only happens once anyway.
Misconception Common misconception with column ordering is that, I should (or could) do the pushing and pulling on mobile devices, and that the desktop views should render in the natural order of the markup. This is wrong.
Reality Bootstrap is a mobile first framework. This means that the order of the columns in your HTML markup should represent the order in which you want them displayed on mobile devices. This mean that the pushing and pulling is done on the larger desktop views. not on mobile devices view..

Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n
will work.
If you use anything else you will cause issues with cut and paste on Windows platforms.
The line breaks will be canonicalised by windows browsers when the form is submitted, but if you send the form down to the browser with \n
linebreaks, you will find that the text will not copy and paste correctly between for example notepad and the textarea.
Interestingly, in spite of the Unix line end convention being \n
, the standard in most text-based network protocols including HTTP, SMTP, POP3, IMAP, and so on is still \r\n
. Yes, it may not make a lot of sense, but that's history and evolving standards for you!
I found one way to access the shared folder without giving the username and password.
We need to change the share folder protect settings in the machine where the folder has been shared.
Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.
By doing the above settings we can access the shared folder without any username/password.
string FileExtn = System.IO.Path.GetExtension(fpdDocument.PostedFile.FileName);
The above method works fine with the firefox and IE , i am able to view all types of files like zip,txt,xls,xlsx,doc,docx,jpg,png
but when i try to find the extension of file from googlechrome , i failed.
JSONP is a simple way to overcome browser restrictions when sending JSON responses from different domains from the client.
But the practical implementation of the approach involves subtle differences that are often not explained clearly.
Here is a simple tutorial that shows JSON and JSONP side by side.
All the code is freely available at Github and a live version can be found at http://json-jsonp-tutorial.craic.com
You can add a click event handler for this:
document.getElementById('button').onclick = function() {
alert("button was clicked");
}?;?
This will alert when it's clicked, if you want to track it for later, just set a variable to true in that function instead of alerting, or variable++
if you want to count the number of clicks, whatever your ultimate use is. You can see an example here.

I've had my drivers installed and the Arduino connected through an unpowered usb hub. Moving it to an USB port of my computer made it work.
You can simply do:
"123456".Select(q => new string(q,1)).ToArray();
to have an enumerable of integers, as per comment request, you can:
"123456".Select(q => int.Parse(new string(q,1))).ToArray();
It is a little weak since it assumes the string actually contains numbers.
I know this is old, but something to point out. If you think everything is as its supposed to, check your .gitignore file :)
You might have the folder locally, but if the folder is in your git ignore then its not on the server, which means Docker cannot find that folder as it does not exist.

You have provided so few details, so I'll try to answer your question without them.
You can use Interpolation:
<img src={{imagePath}} />
Or you can use a template expression:
<img [src]="imagePath" />
In a ngFor loop it might look like this:
<div *ngFor="let student of students">
<img src={{student.ImagePath}} />
</div>
Just to improve YCR's answer:
1) I added black lines on x and y axis. Otherwise they are made transparent too.
2) I added a transparent theme to the legend key. Otherwise, you will get a fill there, which won't be very esthetic.
Finally, note that all those work only with pdf and png formats. jpeg fails to produce transparent graphs.
MyTheme_transparent <- theme(
panel.background = element_rect(fill = "transparent"), # bg of the panel
plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
panel.grid.major = element_blank(), # get rid of major grid
panel.grid.minor = element_blank(), # get rid of minor grid
legend.background = element_rect(fill = "transparent"), # get rid of legend bg
legend.box.background = element_rect(fill = "transparent"), # get rid of legend panel bg
legend.key = element_rect(fill = "transparent", colour = NA), # get rid of key legend fill, and of the surrounding
axis.line = element_line(colour = "black") # adding a black line for x and y axis
)

The first comments out the PRINT instructions, the second prevents PRINT instruction because of a NULL if condition. If optimization is set, the compiler should strip out never executed instructions like: if(0) print("hello world"); or ((void)0);

What are the target browsers? Different browsers set different default CSS rules. Try including a CSS reset, such as the meyerweb CSS reset or normalize.css, to remove those defaults. Google "CSS reset vs normalize" to see the differences.
Expanding on Danny's Solution, but with all sorts of ways to report ages for younger folk (note, today is datetime.date(2015,7,17)
):
def calculate_age(born):

When the age is less than 2 years, reports age in months, rounded down.
When the age is less than 6 months, reports the age in weeks, rounded down.
When the age is less than 2 weeks, reports the age in days.

As Kyle suggested, you can measure the client browser viewport size without taking into account the size of the scroll bars this way.
Sample (Viewport dimensions WITHOUT scroll bars)
// First you forcibly request the scroll bars to hidden regardless if they will be needed or not.
$('body').css('overflow', 'hidden');
// Take your measures.
// (These measures WILL NOT take into account scroll bars dimensions)
var heightNoScrollBars = $(window).height();
var widthNoScrollBars = $(window).width();
// Set the overflow css property back to it's original value (default is auto)
$('body').css('overflow', 'auto');
Alternatively if you wish to find the dimensions of the client viewport while taking into account the size of the scroll bars, then this sample bellow best suits you.
First don't forget to set you body tag to be 100% width and height just to make sure the measurement is accurate.
body {
width: 100%; // if you wish to measure the width and take into account the horizontal scroll bar.
height: 100%; // if you wish to measure the height while taking into account the vertical scroll bar.
}
Sample (Viewport dimensions WITH scroll bars)
// First you forcibly request the scroll bars to be shown regardless if they will be needed or not.
$('body').css('overflow', 'scroll');
// Take your measures.
// (These measures WILL take into account scroll bars dimensions)
var heightWithScrollBars = $(window).height();
var widthWithScrollBars = $(window).width();
// Set the overflow css property back to it's original value (default is auto)
$('body').css('overflow', 'auto');
It looks like there's not a straightforward solution for HTTPS-based cloning regarding GitLab. Therefore if you want a SSH-based cloning, you should take account these three forthcoming steps:
Create properly an SSH key using your email used to sign up. I would use the default filename to key for Windows. Don't forget to introduce a password!
$ ssh-keygen -t rsa -C "[email protected]" -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key ($PWD/.ssh/id_rsa): [\n]
Enter passphrase (empty for no passphrase):[your password]
Enter same passphrase again: [your password]
Your identification has been saved in $PWD/.ssh/id_rsa.
Your public key has been saved in $PWD/.ssh/id_rsa.pub.
Copy and paste all content from the recently id_rsa.pub
generated into Setting>SSH keys>Key from your GitLab profile.
Get locally connected:
$ ssh -i $PWD/.ssh/id_rsa [email protected]
Enter passphrase for key "$PWD/.ssh/id_rsa": [your password]

With multiple phones and beacons at the same location, it's going to be difficult to measure proximity with any high degree of accuracy. Try using the Android "b and l bluetooth le scanner" app, to visualize the signal strengths (distance) variations, for multiple beacons, and you'll quickly discover that complex, adaptive algorithms may be required to provide any form of consistent proximity measurement.
You're going to see lots of solutions simply instructing the user to "please hold your phone here", to reduce customer frustration.
Adding to All of these good answer a summary to how to initialize a structure (union and Array) in C, focused especially on the Designed Initializer.
struct point
{
double x;
double y;
double z;
}
p = {1.2, 1.3};
The Designed Initializer came up since the ISO C99 and is a different and more dynamic way to initialize in C when initializing struct
, union
or an array
.
The biggest difference to standard initialization is that you don't have to declare the elements in a fixed order and you can also omit element.
From The GNU Guide:
Standard C90 requires the elements of an initializer to appear in a fixed order, the same as the order of the elements in the array or structure being initialized.
In ISO C99 you can give the elements in random order, specifying the array indices or structure field names they apply to, and GNU C allows this as an extension in C90 mode as well
Standard Initialization
int a[6] = { 0, 0, 15, 0, 29, 0 };
Designed Initialization
int a[6] = {[4] = 29, [2] = 15 }; // or
int a[6] = {[4]29 , [2]15 }; // or
int widths[] = { [0 ... 9] = 1, [10 ... 99] = 2, [100] = 3 };
Standard Initialization
struct point { int x, y; };
Designed Initialization
struct point p = { .y = 2, .x = 3 }; or
struct point p = { y: 2, x: 3 };
Standard Initialization
int a[6] = { 0, v1, v2, 0, v4, 0 };
Designed Initialization
int a[6] = { [1] = v1, v2, [4] = v4 };
Labeling the elements of an array initializer
int whitespace[256] = { [' '] = 1, ['\t'] = 1, ['\h'] = 1,
['\f'] = 1, ['\n'] = 1, ['\r'] = 1 };
write a series of ‘.fieldname’ and ‘[index]’ designators before an ‘=’ to specify a nested subobject to initialize
struct point ptarray[10] = { [2].y = yv2, [2].x = xv2, [0].x = xv0 };
If you ever end up with the same problem with Scala and SBT:
Go to Project Structure. The shortcut is (CTRL + ALT + SHIFT + S)
On the far left list, choose Project Settings > Modules
On the module list right of that, select the module of your project name (without the build) and choose the sources tab
In middle, expand the folder that the root of your project for me that's /home/<username>/IdeaProjects/<projectName>
Look at the Content Root section on the right side, the red paths are directories that you haven't made. You'll want to put the properties file in a Resources directory. So I created src/main/resources
and put log4j.properties in it. I believe you can also modify the Content Root to put it wherever you want (I didn't do this).
I ran my code with a SBT configuration and it found my log4j.properties file.
After changing the ID it android.R.id.custom, I needed to add the following to get the View to display:
((View) f1.getParent()).setVisibility(View.VISIBLE);
However, this caused the new View to render in a big parent view with no background, breaking the dialog box in two parts (text and buttons, with the new View in between). I finally got the effect that I wanted by inserting my View next to the message:
LinearLayout f1 = (LinearLayout)findViewById(android.R.id.message).getParent().getParent();
I found this solution by exploring the View tree with View.getParent() and View.getChildAt(int). Not really happy about either, though. None of this is in the Android docs and if they ever change the structure of the AlertDialog, this might break.
If you are a Windows user, you may either remove or update your credentials in Credential Manager.
In Windows 10, go to the below path:
Control Panel → All Control Panel Items → Credential Manager
Or search for "credential manager" in your "Search Windows" section in the Start menu.
Then from the Credential Manager, select "Windows Credentials".
Credential Manager will show many items including your outlook and GitHub repository under "Generic credentials"
You click on the drop down arrow on the right side of your Git: and it will show options to edit and remove. If you remove, the credential popup will come next time when you fetch or pull. Or you can directly edit the credentials there.
Although I was expecting an automatic solution (fitting to the screen automatically), resizing solves the problem as well.
import cv2
cv2.namedWindow("output", cv2.WINDOW_NORMAL) # Create window with freedom of dimensions
im = cv2.imread("earth.jpg") # Read image
imS = cv2.resize(im, (960, 540)) # Resize image
cv2.imshow("output", imS) # Show image
cv2.waitKey(0) # Display the image infinitely until any keypress
It works, when you use both lines:
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"
dict(zip([1,2,3,4], [a,b,c,d]))
If the lists are big you should use itertools.izip
.
If you have more keys than values, and you want to fill in values for the extra keys, you can use itertools.izip_longest
.
Here, a
, b
, c
, and d
are variables -- it will work fine (so long as they are defined), but you probably meant ['a','b','c','d']
if you want them as strings.
zip
takes the first item from each iterable and makes a tuple, then the second item from each, etc. etc.
dict
can take an iterable of iterables, where each inner iterable has two items -- it then uses the first as the key and the second as the value for each item.
You need to enter the width % for each cell. But wait, there's a better way to do that, it's called CSS:
<style>
.equalDivide tr td { width:25%; }
</style>
<table class="equalDivide" cellpadding="0" cellspacing="0" width="100%" border="0">
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
You're close.
The LIKE operator works with strings (CHAR, NVARCHAR, etc). so you need to concattenate the '%' symbol to the string...
MS SQL Server:
SELECT * FROM table1,table2 WHERE table1.x LIKE table2.y + '%'
Use of LIKE, however, is often slower than other operations. It's useful, powerful, flexible, but has performance considerations. I'll leave those for another topic though :)
EDIT:
I don't use MySQL, but this may work...
SELECT * FROM table1,table2 WHERE table1.x LIKE CONCAT(table2.y, '%')
From Erlang Programming (2009): Erlang concurrency is fast and scalable. Its processes are lightweight in that the Erlang virtual machine does not create an OS thread for every created process. They are created, scheduled, and handled in the VM, independent of underlying operating system.
Erlang implements a preemptive scheduler, which allows each process to run for a set period of time without blocking a system thread for too long, which gives each process some cpu time to be executed. The number of system threads depends on the number of cores if I'm not mistaking, and processes can be removed from one thread and moved to another if the load becomes uneven, this is all handled by the Erlang scheduler.
It seems to me that simply: ls -lt mydirectory
does the job...
You can use the QMessage object to create a Message Box then add buttons :
QMessageBox msgBox;
msgBox.setWindowTitle("title");
msgBox.setText("Question");
msgBox.setStandardButtons(QMessageBox::Yes);
msgBox.addButton(QMessageBox::No);
msgBox.setDefaultButton(QMessageBox::No);
if(msgBox.exec() == QMessageBox::Yes){
// do something
}else {
// do something else
}
As for me, most elegant way is yield break

This error occurs when, for example, we create a mock inside another mock
mock {
on { x() } doReturn mock {
on { y() } doReturn z()
}
}
The solution to this is to create the child mock in a variable and use the variable in the scope of the parent mock to prevent the mock creation from being explicitly nested.
val liveDataMock = mock {
on { y() } doReturn z()
}
mock {
on { x() } doReturn liveDataMock
}

You may do the following:
git -m master master-old #rename current master
git checkout -b master #create a new branch master
git push -f origin master #force push to master
But force pushing is a bad idea if other people are sharing this repository. Force push will cause their revision history to conflict with the new one.
Please Add this into your gradle file
android {
...
defaultConfig {
...
multiDexEnabled true
}
}
AND also add the below dependency in your gradle
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
OR another option would be: In your manifest file add the MultiDexApplication package from the multidex support library in the application tag.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.multidex.myapplication">
<application
...
android:name="android.support.multidex.MultiDexApplication">
...
</application>
</manifest>
For anyone having this problem with docker-compose
.
When you have more than one project (i.e. in different folders) with similar services you need to run docker-compose stop
in each of your other projects.
Writing to the out stream from the process is the wrong direction. 'out' in that case means from the process to you. Try getting/writing to the input stream for the process and reading from the output stream to see the results.
These are the ways :
1. /proc/meminfo
MemTotal: 8152200 kB
MemFree: 760808 kB
You can write a code or script to parse it.
2. Use sysconf by using below macros
sysconf (_SC_PHYS_PAGES) * sysconf (_SC_PAGESIZE);
3. By using sysinfo system call
int sysinfo(struct sysinfo *info);
struct sysinfo { .
.
unsigned long totalram; /*Total memory size to use */
unsigned long freeram; /* Available memory size*/
.
.
};
So many great answers but since I've just written a function (plotMultipleHistograms()
in 'basicPlotteR' package) function to do this, I thought I would add another answer.
The advantage of this function is that it automatically sets appropriate X and Y axis limits and defines a common set of bins that it uses across all the distributions.
Here's how to use it:
# Install the plotteR package
install.packages("devtools")
devtools::install_github("JosephCrispell/basicPlotteR")
library(basicPlotteR)
# Set the seed
set.seed(254534)
# Create random samples from a normal distribution
distributions <- list(rnorm(500, mean=5, sd=0.5),
rnorm(500, mean=8, sd=5),
rnorm(500, mean=20, sd=2))
# Plot overlapping histograms
plotMultipleHistograms(distributions, nBins=20,
colours=c(rgb(1,0,0, 0.5), rgb(0,0,1, 0.5), rgb(0,1,0, 0.5)),
las=1, main="Samples from normal distribution", xlab="Value")
The plotMultipleHistograms()
function can take any number of distributions, and all the general plotting parameters should work with it (for example: las
, main
, etc.).
Also with python3 you might find convenient to use Extended Iterable Unpacking to handle optional positional arguments without additional dependencies:
try:
_, arg1, arg2, arg3, *_ = sys.argv + [None] * 2
except ValueError:
print("Not enough arguments", file=sys.stderr) # unhandled exception traceback is meaningful enough also
exit(-1)
The above argv
unpack makes arg2
and arg3
"optional" - if they are not specified in argv
, they will be None, while if the first is not specified, ValueError will be thouwn:
Traceback (most recent call last):
File "test.py", line 3, in <module>
_, arg1, arg2, arg3, *_ = sys.argv + [None] * 2
ValueError: not enough values to unpack (expected at least 4, got 3)
If these are the parameters of url-string then you need to add them through '?' and '&' chars, for example http://example.com/index.aspx?username=Api_user&password=Api_password.
If these are the parameters of POST request, then you need to create POST data and write it to request stream. Here is sample method:
private static string doRequestWithBytesPostData(string requestUri, string method, byte[] postData,
CookieContainer cookieContainer,
string userAgent, string acceptHeaderString,
string referer,
string contentType, out string responseUri)
{
var result = "";
if (!string.IsNullOrEmpty(requestUri))
{
var request = WebRequest.Create(requestUri) as HttpWebRequest;
if (request != null)
{
request.KeepAlive = true;
var cachePolicy = new RequestCachePolicy(RequestCacheLevel.BypassCache);
request.CachePolicy = cachePolicy;
request.Expect = null;
if (!string.IsNullOrEmpty(method))
request.Method = method;
if (!string.IsNullOrEmpty(acceptHeaderString))
request.Accept = acceptHeaderString;
if (!string.IsNullOrEmpty(referer))
request.Referer = referer;
if (!string.IsNullOrEmpty(contentType))
request.ContentType = contentType;
if (!string.IsNullOrEmpty(userAgent))
request.UserAgent = userAgent;
if (cookieContainer != null)
request.CookieContainer = cookieContainer;
request.Timeout = Constants.RequestTimeOut;
if (request.Method == "POST")
{
if (postData != null)
{
request.ContentLength = postData.Length;
using (var dataStream = request.GetRequestStream())
{
dataStream.Write(postData, 0, postData.Length);
}
}
}
using (var httpWebResponse = request.GetResponse() as HttpWebResponse)
{
if (httpWebResponse != null)
{
responseUri = httpWebResponse.ResponseUri.AbsoluteUri;
cookieContainer.Add(httpWebResponse.Cookies);
using (var streamReader = new StreamReader(httpWebResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}
}
}
}
responseUri = null;
return null;
}
A quick and easy way to perform the migration is to use the schematic NPM package schematics-scss-migrate. this package rename all css to scss file :
ng add schematics-scss-migrate
You could use this to wrap urllib2:
def URLRequest(url, params, method="GET"):
if method == "POST":
return urllib2.Request(url, data=urllib.urlencode(params))
else:
return urllib2.Request(url + "?" + urllib.urlencode(params))
That will return a Request object that has result data and response codes.
My Experience with this issue using WPF C# coping to clipboard and System.Threading.ThreadStateException
is here with my code that worked correctly with all browsers:
Thread thread = new Thread(() => Clipboard.SetText("String to be copied to clipboard"));
thread.SetApartmentState(ApartmentState.STA); //Set the thread to STA
thread.Start();
thread.Join();
credits to this post here
But this works only on localhost, so don't try this on a server, as it's not going to work.
On server-side, I did it by using zeroclipboard
. The only way, after a lot of research.
STA (Single Threaded Apartment) is basically the concept that only one thread will interact with your code at a time. Calls into your apartment are marshaled via windows messages (using a non-visible) window. This allows calls to be queued and wait for operations to complete.
MTA (Multi Threaded Apartment) is where many threads can all operate at the same time and the onus is on you as the developer to handle the thread security.
There is a lot more to learn about threading models in COM, but if you are having trouble understanding what they are then I would say that understanding what the STA is and how it works would be the best starting place because most COM objects are STA’s.
Apartment Threads, if a thread lives in the same apartment as the object it is using then it is an apartment thread. I think this is only a COM concept because it is only a way of talking about the objects and threads they interact with…
Query for just a single known column:
session.query(MyTable.col1).count()
on windows subsystem for linux I had to navigate to the subsystem root by cd ~/
then touch .gitignore
and then update the global gitignore configuration in there.
I hope it helps someone.
By 'return non-false', they mean to return any value which would not work out to boolean false. So you could return true
, 1
, 'non-false'
, or whatever else you can think up.
Basically in JDBC most of these properties are not configurable in the API like that, rather they depend on implementation. The way JDBC handles this is by allowing the connection URL to be different per vendor.
So what you do is register the driver so that the JDBC system can know what to do with the URL:
DriverManager.registerDriver((Driver) Class.forName("com.mysql.jdbc.Driver").newInstance());
Then you form the URL:
String url = "jdbc:mysql://[host][,failoverhost...][:port]/[database][?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]"
And finally, use it to get a connection:
Connection c = DriverManager.getConnection(url);
In more sophisticated JDBC, you get involved with connection pools and the like, and application servers often have their own way of registering drivers in JNDI and you look up a DataSource from there, and call getConnection on it.
In terms of what properties MySQL supports, see here.
EDIT: One more thought, technically just having a line of code which does Class.forName("com.mysql.jdbc.Driver") should be enough, as the class should have its own static initializer which registers a version, but sometimes a JDBC driver doesn't, so if you aren't sure, there is little harm in registering a second one, it just creates a duplicate object in memeory.
I had a similar problem. If all you want is for some info to be displayed when you hover over a marker, instead of clicking it, then I found that a good alternative to using an info Window was to set a title on the marker. That way whenever you hover the mouse over the marker the title displays like an ALT tag. 'marker.setTitle('Marker '+id);' It removes the need to create a listener for the marker too
This is a variation of n3rds solution above. No sorting by using ORDER BY is needed, as MIN() is used.
Remember that CustomerID (or whatever other numerical column you use for progress) must have a unique constraint. Furthermore, to make it as fast as possible CustomerID must be indexed on.
-- Declare & init
DECLARE @CustomerID INT = (SELECT MIN(CustomerID) FROM Sales.Customer); -- First ID
DECLARE @Data1 VARCHAR(200);
DECLARE @Data2 VARCHAR(200);
-- Iterate over all customers
WHILE @CustomerID IS NOT NULL
BEGIN
-- Get data based on ID
SELECT @Data1 = Data1, @Data2 = Data2
FROM Sales.Customer
WHERE [ID] = @CustomerID ;
-- call your sproc
EXEC dbo.YOURSPROC @Data1, @Data2
-- Get next customerId
SELECT @CustomerID = MIN(CustomerID)
FROM Sales.Customer
WHERE CustomerID > @CustomerId
END
I use this approach on some varchars I need to look over, by putting them in a temporary table first, to give them an ID.
This works for me:
start: function(event, ui) {
var start_pos = ui.item.index();
ui.item.data('start_pos', start_pos);
},
update: function (event, ui) {
var start_pos = ui.item.data('start_pos');
var end_pos = ui.item.index();
//$('#sortable li').removeClass('highlights');
}

Here is an example using css3:
CSS:
html, body {
height: 100%;
margin: 0;
}
#wrap {
padding: 10px;
min-height: -webkit-calc(100% - 100px); /* Chrome */
min-height: -moz-calc(100% - 100px); /* Firefox */
min-height: calc(100% - 100px); /* native */
}
.footer {
position: relative;
clear:both;
}
HTML:
<div id="wrap">
body content....
</div>
<footer class="footer">
footer content....
</footer>
Update
As @Martin pointed, the ´position: relative´ is not mandatory on the .footer
element, the same for clear:both
. These properties are only there as an example. So, the minimum css necessary to stick the footer on the bottom should be:
html, body {
height: 100%;
margin: 0;
}
#wrap {
min-height: -webkit-calc(100% - 100px); /* Chrome */
min-height: -moz-calc(100% - 100px); /* Firefox */
min-height: calc(100% - 100px); /* native */
}
Also, there is an excellent article at css-tricks showing different ways to do this: https://css-tricks.com/couple-takes-sticky-footer/
Android Studio now has learned to work with GitHub fork repositories (you don't even have to add "upstream" remote repository by console command).
Open menu VCS ? Git
And pay attention to the two last popup menu items:
Rebase my GitHub fork
Create Pull Request
Try them. I use the first one to synchronize my local repository. Anyway the branches from the parent remote repository ("upstream") will be accessible in Android Studio after you click "Rebase my GitHub fork", and you will be able to operate with them easily.
(I use Android Studio 3.0 with "Git integration" and "GitHub" plugins.)

To catch errors with subprocess.check_output()
, you can use CalledProcessError
. If you want to use the output as string, decode it from the bytecode.
# \return String of the output, stripped from whitespace at right side; or None on failure.
def runls():
import subprocess
try:
byteOutput = subprocess.check_output(['ls', '-a'], timeout=2)
return byteOutput.decode('UTF-8').rstrip()
except subprocess.CalledProcessError as e:
print("Error in ls -a:\n", e.output)
return None
Depending on what you want to do, you can try:
browser.waitForAngular();
or
btnLoginEl.click().then(function() {
// do some stuff
});
to solve the promise. It would be better if you can do that in the beforeEach
.
NB: I noticed that the expect() waits for the promise inside (i.e. getCurrentUrl) to be solved before comparing.
I find, that psql show password prompt even you define PGPASSWORD variable, but you can specify -w option for psql to omit password prompt.
Assuming that you know that the root elements are zero, here's the pseudocode to output to text:
function PrintLevel (int curr, int level)
//print the indents
for (i=1; i<=level; i++)
print a tab
print curr \n;
for each child in the table with a parent of curr
PrintLevel (child, level+1)
for each elementID where the parentid is zero
PrintLevel(elementID, 0)

First of all you have to define 2 variables globally inside your view controller.
var player: AVPlayer!
var playerViewController: AVPlayerViewController!
Here I'm adding player to a desired view.
@IBOutlet weak var playerView: UIView!
Then add following code to the viewDidLoad method.
let videoURL = URL(string: "videoUrl")
self.player = AVPlayer(url: videoURL!)
self.playerViewController = AVPlayerViewController()
playerViewController.player = self.player
playerViewController.view.frame = self.playerView.frame
playerViewController.player?.pause()
self.playerView.addSubview(playerViewController.view)
If you are not defining player and playerViewController globally, you won't be able to embed player.
UPDATE for .NET 5!
The below applies on/after NOV2020 when .NET 5 is officially out.
(see quick terminology section below, not just the How-to's)
dotnet publish --output "{any directory}" --runtime {runtime} --configuration {Debug|Release} -p:PublishSingleFile={true|false} -p:PublishTrimmed={true|false} --self-contained {true|false}
example:
dotnet publish --output "c:/temp/myapp" --runtime win-x64 --configuration Release -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true
*In above 2 cases, the latest .net5 SDK will be automatically installed on your PC.
Click Start and choose Folder target, click next and choose Folder
Enter any folder location, and click Finish
Choose a Target Runtime and tick on Produce Single File and save.*
Click Publish
Open a terminal in the location you published your app, and run the .exe. Example:
Target Runtime
See the list of RID's
Deployment Mode
Enable ReadyToRun compilation
TLDR: it's .Net5's equivalent of Ahead of Time Compilation (AOT). Pre-compiled to native code, app would usually boot up faster. App more performant (or not!), depending on many factors. More info here
Trim unused assemblies
When set to true, dotnet will generate a very lean and small .exe and only include what it needs. Be careful here. Example: when using reflection in your app you probably don't want to set this flag to true.
Previous Post
UPDATE (31-OCT-2019)
For anyone that wants to do this via a GUI and:
Note
Notice the large file size for such a small application
You can add the "PublishTrimmed" property. The application will only include components that are used by the application. Caution: don't do this if you are using reflection
Publish again
as a beginner, i import acm packages, and in this package, run() starts executing of a thread, init() initialize the Java Applet.
For add environment variable please add \ after bin like below
C:\Program Files\MongoDB\Server\3.2\bin\
Then try below code in command prompt to run mongo server from parent folder of data folder.
mongod -dbpath ./data
For my case I am unable to run mongo from command prompt(normal mode). You should run as administrator. It also works on git bash.
You can use Random.Next(int maxValue)
:
Return: A 32-bit signed integer greater than or equal to zero, and less than maxValue; that is, the range of return values ordinarily includes zero but not maxValue. However, if maxValue equals zero, maxValue is returned.
var r = new Random();
// print random integer >= 0 and < 100
Console.WriteLine(r.Next(100));
For this case however you could use Random.Next(int minValue, int maxValue)
, like this:
// print random integer >= 1 and < 101
Console.WriteLine(r.Next(1, 101);)
// or perhaps (if you have this specific case)
Console.WriteLine(r.Next(100) + 1);
With pure CSS, nothing fancy with :before
and :after
, no transforms, you can turn off the default appearance and then style it with an inline background image like the following example. This works in Chrome, Firefox, Safari, and now Edge (Chromium Edge).
INPUT[type=checkbox]:focus
{
outline: 1px solid rgba(0, 0, 0, 0.2);
}
INPUT[type=checkbox]
{
background-color: #DDD;
border-radius: 2px;
appearance: none;
-webkit-appearance: none;
-moz-appearance: none;
width: 17px;
height: 17px;
cursor: pointer;
position: relative;
top: 5px;
}
INPUT[type=checkbox]:checked
{
background-color: #409fd6;
background: #409fd6 url("data:image/gif;base64,R0lGODlhCwAKAIABAP////3cnSH5BAEKAAEALAAAAAALAAoAAAIUjH+AC73WHIsw0UCjglraO20PNhYAOw==") 3px 3px no-repeat;
}

<form>
<label><input type="checkbox"> I Agree To Terms & Conditions</label>
</form>

You can use GCD (in the example with a 10 second delay):
let triggerTime = (Int64(NSEC_PER_SEC) * 10)
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), { () -> Void in
self.functionToCall()
})
DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
self.functionToCall()
})
DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
//call any function
}
Edit: The bitset stuff below is maybe an interesting read, but the answer itself is a bit dated. Some of this functionality is changing around in 2.x. Also Slawek points out in another answer that the terms
query is an easy way to DRY up the search in this case. Refactored at the end for current best practices. —nz
You'll probably want a Bool Query (or more likely Filter alongside another query), with a should
clause.
The bool query has three main properties: must
, should
, and must_not
. Each of these accepts another query, or array of queries. The clause names are fairly self-explanatory; in your case, the should
clause may specify a list filters, a match against any one of which will return the document you're looking for.
From the docs:
In a boolean query with no
must
clauses, one or moreshould
clauses must match a document. The minimum number of should clauses to match can be set using theminimum_should_match
parameter.
Here's an example of what that Bool query might look like in isolation:
{
"bool": {
"should": [
{ "term": { "tag": "c" }},
{ "term": { "tag": "d" }}
]
}
}
And here's another example of that Bool query as a filter within a more general-purpose Filtered Query:
{
"filtered": {
"query": {
"match": { "title": "hello world" }
},
"filter": {
"bool": {
"should": [
{ "term": { "tag": "c" }},
{ "term": { "tag": "d" }}
]
}
}
}
}
Whether you use Bool as a query (e.g., to influence the score of matches), or as a filter (e.g., to reduce the hits that are then being scored or post-filtered) is subjective, depending on your requirements.
It is generally preferable to use Bool in favor of an Or Filter, unless you have a reason to use And/Or/Not (such reasons do exist). The Elasticsearch blog has more information about the different implementations of each, and good examples of when you might prefer Bool over And/Or/Not, and vice-versa.
Elasticsearch blog: All About Elasticsearch Filter Bitsets
Update with a refactored query...
Now, with all of that out of the way, the terms
query is a DRYer version of all of the above. It does the right thing with respect to the type of query under the hood, it behaves the same as the bool
+ should
using the minimum_should_match
options, and overall is a bit more terse.
Here's that last query refactored a bit:
{
"filtered": {
"query": {
"match": { "title": "hello world" }
},
"filter": {
"terms": {
"tag": [ "c", "d" ],
"minimum_should_match": 1
}
}
}
}
I know this is very late to the game ... but this always works for me:
ssh-add ~/.ssh/KEY_PAIR_NAME.pem
ssh user_name@<instance public dns/ip>
e.g.
ssh [email protected]
hope this helps someone.
From the doc :
Capturing groups</a> are indexed from left
* to right, starting at one. Group zero denotes the entire pattern, so
* the expression m.group(0) is equivalent to m.group().
So capture group 0 send the whole line.
Your code can be fixed as follows:
import numpy as np, cv
vis = np.zeros((384, 836), np.float32)
h,w = vis.shape
vis2 = cv.CreateMat(h, w, cv.CV_32FC3)
vis0 = cv.fromarray(vis)
cv.CvtColor(vis0, vis2, cv.CV_GRAY2BGR)
Short explanation:
np.uint32
data type is not supported by OpenCV (it supports uint8
, int8
, uint16
, int16
, int32
, float32
, float64
)cv.CvtColor
can't handle numpy arrays so both arguments has to be converted to OpenCV type. cv.fromarray
do this conversion.cv.CvtColor
must have the same depth. So I've changed source type to 32bit float to match the ddestination.Also I recommend you use newer version of OpenCV python API because it uses numpy arrays as primary data type:
import numpy as np, cv2
vis = np.zeros((384, 836), np.float32)
vis2 = cv2.cvtColor(vis, cv2.COLOR_GRAY2BGR)
If this is really bothering you, why not write your own method isBetween(orderBean.getFiles().size(),0,5)
?
Another option is to use isEmpty
as it is a tad clearer:
if(!orderBean.getFiles().isEmpty() && orderBean.getFiles().size() < 5)
//Returns a random number in the range (0.0f, 1.0f).
// 0111 1111 1111 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000
// seee eeee eeee vvvv vvvv vvvv vvvv vvvv vvvv vvvv vvvv vvvv vvvv vvvv vvvv vvvv
// sign = 's'
// exponent = 'e'
// value = 'v'
double DoubleRand() {
typedef unsigned long long uint64;
uint64 ret = 0;
for (int i = 0; i < 13; i++) {
ret |= ((uint64) (rand() % 16) << i * 4);
}
if (ret == 0) {
return rand() % 2 ? 1.0f : 0.0f;
}
uint64 retb = ret;
unsigned int exp = 0x3ff;
retb = ret | ((uint64) exp << 52);
double *tmp = (double*) &retb;
double retval = *tmp;
while (retval > 1.0f || retval < 0.0f) {
retval = *(tmp = (double*) &(retb = ret | ((uint64) (exp--) << 52)));
}
if (rand() % 2) {
retval -= 0.5f;
}
return retval;
}
This should do the trick, I used this Wikipedia article to help create this. I believe it to be as good as drand48();
You can use the latest scope provided by Laravel with the field you would like to filter, let's say it'll be ordered by ID, then:
Model::latest('id')->first();
So in this way, you can avoid ordering by created_at
field by default at Laravel.
ALTER DATABASE [DatabaseName] SET READ_WRITE
If you are creating an array then there is no difference, however, the following is neater:
String[] suit = {
"spades",
"hearts",
"diamonds",
"clubs"
};
But, if you want to pass an array into a method you have to call it like this:
myMethod(new String[] {"spades", "hearts"});
myMethod({"spades", "hearts"}); //won't compile!
double r2()
{
return (rand() % 10001) / 10000.0;
}
Here I have written a few steps for How to Get RegID and Notification starting from scratch
You can find a complete tutorial here:
Code snippet to get Registration ID (Device Token for Push Notification).
Configure project for GCM
To enable GCM in our project we need to add a few permissions to our manifest file. Go to AndroidManifest.xml
and add this code:
Add Permissions
<uses-permission android:name="android.permission.INTERNET”/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name=“.permission.RECEIVE" />
<uses-permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE" />
<permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
Add GCM Broadcast Receiver declaration in your application tag:
<application
<receiver
android:name=".GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" ]]>
<intent-filter]]>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="" />
</intent-filter]]>
</receiver]]>
<application/>
Add GCM Service declaration
<application
<service android:name=".GcmIntentService" />
<application/>
Now Go to your Launch/Splash Activity
Add Constants and Class Variables
private final static int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
public static final String EXTRA_MESSAGE = "message";
public static final String PROPERTY_REG_ID = "registration_id";
private static final String PROPERTY_APP_VERSION = "appVersion";
private final static String TAG = "LaunchActivity";
protected String SENDER_ID = "Your_sender_id";
private GoogleCloudMessaging gcm =null;
private String regid = null;
private Context context= null;
Update OnCreate and OnResume methods
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_launch);
context = getApplicationContext();
if (checkPlayServices()) {
gcm = GoogleCloudMessaging.getInstance(this);
regid = getRegistrationId(context);
if (regid.isEmpty()) {
registerInBackground();
} else {
Log.d(TAG, "No valid Google Play Services APK found.");
}
}
}
@Override
protected void onResume() {
super.onResume();
checkPlayServices();
}

Best thing I found is: https://github.com/mattt/TTTAttributedLabel
It's a UILabel subclass so you can just drop it in, and then to change the line height:
myLabel.lineHeightMultiple = 0.85;
myLabel.leading = 2;
If you have a String object you want to tokenize, favor using String's split method over a StringTokenizer. If you're parsing text data from a source outside your program, like from a file, or from the user, that's where a Scanner comes in handy.
You can follow these steps :
$('SelectorToPrint').printElement();
Change Your Web.Config file as below. It will act like charm.
In node <system.webServer>
add below portion of code
<modules runAllManagedModulesForAllRequests="true">

This may work:
jdialog.addWindowListener(new WindowAdapter() {
public void windowClosed(WindowEvent e) {
System.out.println("jdialog window closed event received");
}

You're trying to declare strategy
twice, and that's why you're getting the above error. The following works without any complaints (compiled with gcc -ansi -pedantic -Wall
):
#include <stdio.h>
enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;
int main(int argc, char** argv){
printf("strategy: %d\n", strategy);
return 0;
}
If instead of the above, the second line were changed to:
...
enum { RANDOM, IMMEDIATE, SEARCH } strategy;
strategy = IMMEDIATE;
...
From the warnings, you could easily see your mistake:
enums.c:5:1: warning: data definition has no type or storage class [enabled by default]
enums.c:5:1: warning: type defaults to ‘int’ in declaration of ‘strategy’ [-Wimplicit-int]
enums.c:5:1: error: conflicting types for ‘strategy’
enums.c:4:36: note: previous declaration of ‘strategy’ was here
So the compiler took strategy = IMMEDIATE
for a declaration of a variable called strategy
with default type int
, but there was already a previous declaration of a variable with this name.
However, if you placed the assignment in the main()
function, it would be a valid code:
#include <stdio.h>
enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;
int main(int argc, char** argv){
strategy=SEARCH;
printf("strategy: %d\n", strategy);
return 0;
}
You can try and add a new run configuration: Run -> Run Configurations ... -> Select "Java Appliction" and click "New".
Alternatively use the shortcut: place the cursor in the class, then press Alt + Shift + X
to open up a context menu, then press J
.
I spent more than a week to convert the whole project and came to a solution below:
First, de-integrate the cocopods dependency from the project and then start converting the project to the latest swift version.
Go to Project Directory in the Terminal and Type:
pod deintegrate
This will de-integrate cocopods from the project and No traces of CocoaPods will be left in the project. But at the same time, it won't delete the xcworkspace and podfiles. It's ok if they are present.
Now you have to open xcodeproj(not xcworkspace) and you will get lots of errors because you have called cocoapods dependency methods in your main projects.
So to remove those errors you have two options:
Once all the errors get removed you can convert the code to the latest swift version.
Sometimes if you are getting weird errors then try cleaning derived data and try again.
if
takes a command and checks its return value. [
is just a command.
if grep -q ...
then
....
else
....
fi
A quick string "GOTCHA" with JSON Unmarshall which will add wrapping quotes to strings.
(example: the string value of {"first_name":" I have whitespace "}
will convert to "\" I have whitespace \""
)
Before you can trim anything, you'll need to remove the extra quotes first:
// ScrubString is a string that might contain whitespace that needs scrubbing.
type ScrubString string
// UnmarshalJSON scrubs out whitespace from a valid json string, if any.
func (s *ScrubString) UnmarshalJSON(data []byte) error {
ns := string(data)
// Make sure we don't have a blank string of "\"\"".
if len(ns) > 2 && ns[0] != '"' && ns[len(ns)] != '"' {
*s = ""
return nil
}
// Remove the added wrapping quotes.
ns, err := strconv.Unquote(ns)
if err != nil {
return err
}
// We can now trim the whitespace.
*s = ScrubString(strings.TrimSpace(ns))
return nil
}
You need some sort of Inter Process Communication. Use a pipe or a shared buffer.
Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();
You can .write()
the content into the iframe document. Example:
<iframe id="FileFrame" src="about:blank"></iframe>
<script type="text/javascript">
var doc = document.getElementById('FileFrame').contentWindow.document;
doc.open();
doc.write('<html><head><title></title></head><body>Hello world.</body></html>');
doc.close();
</script>
Here is a full program example of a for-each macro in C99:
#include <stdio.h>
typedef struct list_node list_node;
struct list_node {
list_node *next;
void *data;
};
#define FOR_EACH(item, list) \
for (list_node *(item) = (list); (item); (item) = (item)->next)
int
main(int argc, char *argv[])
{
list_node list[] = {
{ .next = &list[1], .data = "test 1" },
{ .next = &list[2], .data = "test 2" },
{ .next = NULL, .data = "test 3" }
};
FOR_EACH(item, list)
puts((char *) item->data);
return 0;
}
"set -e
" is probably the easiest way to do this. Just put that before any commands in your program.
What about -mmin
?
find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
-exec rm -f {} \;
From man find:
-mmin n File's data was last modified n minutes ago.
Also, make sure to test this first!
... -exec echo rm -f '{}' \; ^^^^ Add the 'echo' so you just see the commands that are going to get run instead of actual trying them first.
In Managed C++, static class syntax is:-
public ref class BitParser abstract sealed
{
public:
static bool GetBitAt(...)
{

}
... better late than never...
Why JSON RPC:
In case of REST APIs, we have to define a controller for each functionality/method we might need. As a result if we have 10 methods that we want accessible to a client, we have to write 10 controllers to interface the client's request to a particular method.
Another factor is, even though we have different controllers for each method/functionality, the client has to remember wether to use POST or GET. This complicates things further. On top of that to send data, one has to set the content type of the request if POST is used.
In case of JSON RPC, things are greatly simplified because most JSONRPC servers operate on POST HTTP methods and the content type is always application/json. This takes the load off of remembering to use proper HTTP method and content settings on client side.
One doesn't have to create separate controllers for different methods/functionalities the server wants to expose to a client.
Why REST:
You have separate URLs for different functionality the server wants to expose to client side. As a result, you can embed these urls.
Most of these points are debatable and completely depend upon the need of a person.
Decision tree between ES5, ES6 and TypeScript
Do you mind having a build step?
Do you want to use types?
ES5 is the JavaScript you know and use in the browser today it is what it is and does not require a build step to transform it into something that will run in today's browsers
ES6 (also called ES2015) is the next iteration of JavaScript, but it does not run in today's browsers. There are quite a few transpilers that will export ES5 for running in browsers. It is still a dynamic (read: untyped) language.
TypeScript provides an optional typing system while pulling in features from future versions of JavaScript (ES6 and ES7).
Note: a lot of the transpilers out there (i.e. babel, TypeScript) will allow you to use features from future versions of JavaScript today and exporting code that will still run in today's browsers.
On GitHub, you can use HTML directly instead of Markdown:
<a href="url"><img src="http://url.to/image.png" align="left" height="48" width="48" ></a>
This should make it.
Adrian's answer threw "fatal: This operation must be run in a work tree." The following is what worked for us.
git worktree add <new-dir> --no-checkout --detach
cd <new-dir>
git checkout <some-ref> -- <existing-dir>
Notes:
--no-checkout
Do not checkout anything into the new worktree.--detach
Do not create a new branch for the new worktree.<some-ref>
works with any ref, for instance, it works with HEAD~1
.git worktree prune
. I'd like expand on @JustAGuy's answer. The method I prefer is to use AWS CLI
to create a config file. The reason is, with the config file, the CLI
or the SDK
will automatically look for credentials in the ~/.aws
folder. And the good thing is that AWS CLI
is written in python.
You can get cli from pypi if you don't have it already. Here are the steps to get cli set up from terminal
$> pip install awscli #can add user flag
$> aws configure
AWS Access Key ID [****************ABCD]:[enter your key here]
AWS Secret Access Key [****************xyz]:[enter your secret key here]
Default region name [us-west-2]:[enter your region here]
Default output format [None]:
After this you can access boto
and any of the api without having to specify keys (unless you want to use a different credentials).
Today, I can use Promise
in Node.js
as a plain Javascript method.
A simple and basic example to Promise
(with KISS way):
Plain Javascript Async API code:
function divisionAPI (number, divider, successCallback, errorCallback) {
if (divider == 0) {
return errorCallback( new Error("Division by zero") )
}
successCallback( number / divider )
}
Promise
Javascript Async API code:
function divisionAPI (number, divider) {
return new Promise(function (fulfilled, rejected) {
if (divider == 0) {
return rejected( new Error("Division by zero") )
}
fulfilled( number / divider )
})
}
(I recommend visiting this beautiful source)
Also Promise
can be used with together async\await
in ES7
to make the program flow wait for a fullfiled
result like the following:
function getName () {
return new Promise(function (fulfilled, rejected) {
var name = "John Doe";
// wait 3000 milliseconds before calling fulfilled() method
setTimeout (
function() {
fulfilled( name )
},
3000
)
})
}
async function foo () {
var name = await getName(); // awaits for a fulfilled result!
console.log(name); // the console writes "John Doe" after 3000 milliseconds
}
foo() // calling the foo() method to run the code
Another usage with the same code by using .then()
method
function getName () {
return new Promise(function (fulfilled, rejected) {
var name = "John Doe";
// wait 3000 milliseconds before calling fulfilled() method
setTimeout (
function() {
fulfilled( name )
},
3000
)
})
}
// the console writes "John Doe" after 3000 milliseconds
getName().then(function(name){ console.log(name) })
Promise
can also be used on any platform that is based on Node.js like react-native
.
Bonus: An hybrid method
(The callback method is assumed to have two parameters as error and result)
function divisionAPI (number, divider, callback) {
return new Promise(function (fulfilled, rejected) {
if (divider == 0) {
let error = new Error("Division by zero")
callback && callback( error )
return rejected( error )
}
let result = number / divider
callback && callback( null, result )
fulfilled( result )
})
}
The above method can respond result for old fashion callback and Promise usages.
Hope this helps.
If you have Exchange 2010:
(In my case, the error message didn't contain " for [email protected]")
This shows how to add a receive connector: http://exchangeserverpro.com/how-to-configure-a-relay-connector-for-exchange-server-2010/
But I also needed to perform a step found here: http://recover-email.blogspot.com.au/2013/12/how-to-solve-exchange-smtp-server-error.html
- Go to Exchange Management Shell and run the command
- Get-ReceiveConnector "JiraTest" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"
While working on this, I ran the following on the affected server's PowerShell console until the error went away:
Send-MailMessage -From "[email protected]" -To "[email protected]" -Subject "Test Email" -Body "This is a test"
Have a look at the example http://www.cplusplus.com/reference/clibrary/cstdarg/va_arg/, they pass the number of arguments to the method but you can ommit that and modify the code appropriately (see the example).
Most of the options are problematic for multi-select. Place Title attribute, and make first option as data-hidden="true"
<select class="selectpicker" title="Some placeholder text...">
<option data-hidden="true"></option>
<option>First</option>
<option>Second</option>
</select>

Try... csv download.
<?php
mysql_connect('hostname', 'username', 'password');
mysql_select_db('dbname');
$qry = mysql_query("SELECT * FROM tablename");
$data = "";
while($row = mysql_fetch_array($qry)) {
$data .= $row['field1'].",".$row['field2'].",".$row['field3'].",".$row['field4']."\n";
}
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="filename.csv"');
echo $data; exit();
?>
Following procedure helped me solve this issue but i don't know why.
Even if it seems to be the same query executing it did not throw this error
dup2( STDIN_FILENO, newfd )
And read:
char reading[ 1025 ];
int fdin = 0, r_control;
if( dup2( STDIN_FILENO, fdin ) < 0 ){
perror( "dup2( )" );
exit( errno );
}
memset( reading, '\0', 1025 );
while( ( r_control = read( fdin, reading, 1024 ) ) > 0 ){
printf( "<%s>", reading );
memset( reading, '\0', 1025 );
}
if( r_control < 0 )
perror( "read( )" );
close( fdin );
But, I think that fcntl
can be a better solution

For System.Timers.Timer, on separate thread, if SynchronizingObject is not set.
static System.Timers.Timer DummyTimer = null;
static void Main(string[] args)
{
try
{
Console.WriteLine("Main Thread Id: " + System.Threading.Thread.CurrentThread.ManagedThreadId);
DummyTimer = new System.Timers.Timer(1000 * 5); // 5 sec interval
DummyTimer.Enabled = true;
DummyTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnDummyTimerFired);
DummyTimer.AutoReset = true;
DummyTimer.Start();
Console.WriteLine("Hit any key to exit");
Console.ReadLine();
}
catch (Exception Ex)
{
Console.WriteLine(Ex.Message);
}
return;
}
static void OnDummyTimerFired(object Sender, System.Timers.ElapsedEventArgs e)
{
Console.WriteLine(System.Threading.Thread.CurrentThread.ManagedThreadId);
return;
}
Output you'd see if DummyTimer fired on 5 seconds interval:
Main Thread Id: 9
12
12
12
12
12
...
So, as seen, OnDummyTimerFired is executed on Workers thread.
No, further complication - If you reduce interval to say 10 ms,
Main Thread Id: 9
11
13
12
22
17
...
This is because if prev execution of OnDummyTimerFired isn't done when next tick is fired, then .NET would create a new thread to do this job.
Complicating things further, "The System.Timers.Timer class provides an easy way to deal with this dilemma—it exposes a public SynchronizingObject property. Setting this property to an instance of a Windows Form (or a control on a Windows Form) will ensure that the code in your Elapsed event handler runs on the same thread on which the SynchronizingObject was instantiated."

Try this function for get root directory path:
get_template_directory_uri();
The solution is simple.
After installing Node, you should restart your VScode and run npm install command.
What your code tries to do is call a program named cd ..
. What you want is call a command named cd
.
But cd
is a shell internal. So you can only call it as
subprocess.call('cd ..', shell=True) # pointless code! See text below.
But it is pointless to do so. As no process can change another process's working directory (again, at least on a UNIX-like OS, but as well on Windows), this call will have the subshell change its dir and exit immediately.
What you want can be achieved with os.chdir()
or with the subprocess
named parameter cwd
which changes the working directory immediately before executing a subprocess.
For example, to execute ls
in the root directory, you either can do
wd = os.getcwd()
os.chdir("/")
subprocess.Popen("ls")
os.chdir(wd)
or simply
subprocess.Popen("ls", cwd="/")

You have a couple of options:
Remove the out-of-the-box ROOT/
directory from tomcat and rename your war file to ROOT.war
before deploying it.
Deploy your war as (from your example) war_name.war
and configure the context root in conf/server.xml
to use your war file :
<Context path="" docBase="war_name" debug="0" reloadable="true"></Context>
The first one is easier, but a little more kludgy. The second one is probably the more elegant way to do it.
"2.7.0_bf4fda703454".split("_")
gives a list of strings:
In [1]: "2.7.0_bf4fda703454".split("_")
Out[1]: ['2.7.0', 'bf4fda703454']
This splits the string at every underscore. If you want it to stop after the first split, use "2.7.0_bf4fda703454".split("_", 1)
.
If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables:
In [8]: lhs, rhs = "2.7.0_bf4fda703454".split("_", 1)
In [9]: lhs
Out[9]: '2.7.0'
In [10]: rhs
Out[10]: 'bf4fda703454'
An alternative is to use partition()
. The usage is similar to the last example, except that it returns three components instead of two. The principal advantage is that this method doesn't fail if the string doesn't contain the separator.
If you want for some reason to convert your file to base-64 string. Like if you want to pass it via internet, etc... you can do this
Byte[] bytes = File.ReadAllBytes("path");
String file = Convert.ToBase64String(bytes);
And correspondingly, read back to file:
Byte[] bytes = Convert.FromBase64String(b64Str);
File.WriteAllBytes(path, bytes);
You could use wait for exit or you can catch the HasExited property and update your UI to keep the user "informed" (expectation management):
System.Diagnostics.Process process = System.Diagnostics.Process.Start("cmd.exe");
while (!process.HasExited)
{
//update UI
}
//done

<input type='text' name='stud_name' id="stud_name" value=""/>
Age: <select name='age' id="age">
<option value='1' stud_name='sre'>23</option>
<option value='2' stud_name='sam'>24</option>
<option value='5' stud_name='john'>25</option>
</select>
<input type='submit' name='submit'/>
</form>
jquery code :
<script type="text/javascript" src="jquery.js"></script>
<script>
$(function() {
$("#age").change(function(){
var option = $('option:selected', this).attr('stud_name');
$('#stud_name').val(option);
});
});
</script>

This is a bit more readable:
Object[] allValues = all.getDeclaringClass().getEnumConstants();

If the call to cmp_configs is inside its own function definition, you should be fine. I'll give an example.
def a():
b() # b() hasn't been defined yet, but that's fine because at this point, we're not
# actually calling it. We're just defining what should happen when a() is called.
a() # This call fails, because b() hasn't been defined yet,
# and thus trying to run a() fails.
def b():
print "hi"
a() # This call succeeds because everything has been defined.
In general, putting your code inside functions (such as main()) will resolve your problem; just call main() at the end of the file.
A memory error means that your program has ran out of memory. This means that your program somehow creates too many objects.
In your example, you have to look for parts of your algorithm that could be consuming a lot of memory. I suspect that your program is given very long strings as inputs. Therefore, s[i:j+1]
could be the culprit, since it creates a new list. The first time you use it though, it is not necessary because you don't use the created list. You could try to see if the following helps:
if j + 1 < a:
sub_strings.append(s[i:j+1])
To replace the second list creation, you should definitely use a buffer object, as suggested by glglgl.
Also note that since you use if j >= i:
, you don't need to start your xrange
at 0. You can have:
for i in xrange(0, a):
for j in xrange(i, a):
# No need for if j >= i
A more radical alternative would be to try to rework your algorithm so that you don't pre-compute all possible sub-strings. Instead, you could simply compute the substring that are asked.
Try /E
To get a full list of options: xcopy /?
git reset --hard
git push origin HEAD --force
If one or more of the commits is tagged, delete the tag(s) first. Otherwise the tagged commit is not removed.
In Visual Studio the Diff can be called using Command Window
and then Tools.DiffFiles
command
Command Window
by hotkeys Ctrl + W, A
or by menu View -> Other Windows -> Command Window
Tools.DiffFiles "FirstFile.cs" "SecondFile.cs"
I suggest to use
#selector {
text-transform: capitalize;
}
or
#selector::first-letter {
text-transform: uppercase;
}
By the way, check this w3schools link: http://www.w3schools.com/cssref/pr_text_text-transform.asp
The original syntax will work with BASH but not with DASH. On debian systems you might think you are using bash, but maybe dash instead. If /bin/dash/exist then try temporarily renaming dash to something like no.dash, and then create soft a link, aka ln -s /bin/bash /bin/dash and see if that fixes the problem.
There is no Gacutil included in the .net 4.0 standard installation. They have moved the GAC too, from %Windir%\assembly to %Windir%\Microsoft.NET\Assembly.
They havent' even bothered adding a "special view" for the folder in Windows explorer, as they have for the .net 1.0/2.0 GAC.
Gacutil is part of the Windows SDK, so if you want to use it on your developement machine, just install the Windows SDK for your current platform. Then you will find it somewhere like this (depending on your SDK version):
C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools
There is a discussion on the new GAC here: .NET 4.0 has a new GAC, why?
If you want to install something in GAC on a production machine, you need to do it the "proper" way (gacutil was never meant as a tool for installing stuff on production servers, only as a development tool), with a Windows Installer, or with other tools. You can e.g. do it with PowerShell and the System.EnterpriseServices dll.
On a general note, and coming from several years of experience, I would personally strongly recommend against using GAC at all. Your application will always work if you deploy the DLL with each application in its bin folder as well. Yes, you will get multiple copies of the DLL on your server if you have e.g. multiple web apps on one server, but it's definitely worth the flexibility of being able to upgrade one application without breaking the others (by introducing an incompatible version of the shared DLL in the GAC).
Use a for
loop to iterate through your array. For each string, create a new option
element, assign the string as its innerHTML
and value
, and then append it to the select
element.
var cuisines = ["Chinese","Indian"];
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
var opt = document.createElement('option');
opt.innerHTML = cuisines[i];
opt.value = cuisines[i];
sel.appendChild(opt);
}
UPDATE: Using createDocumentFragment
and forEach
If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment
acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild
operation so that the DOM only updates once, instead of n
times.
var cuisines = ["Chinese","Indian"];
var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();
cuisines.forEach(function(cuisine, index) {
var opt = document.createElement('option');
opt.innerHTML = cuisine;
opt.value = cuisine;
fragment.appendChild(opt);
});
sel.appendChild(fragment);
The basic steps are:
Use a custom authentication provider
<bean id="myAuthenticationProvider" class="myProviderImplementation" scope="singleton">
...
</bean>
Make your custom provider return a custom UserDetails
implementation. This UserDetailsImpl
will have a getAuthorities()
like this:
public Collection<GrantedAuthority> getAuthorities() {
List<GrantedAuthority> permissions = new ArrayList<GrantedAuthority>();
for (GrantedAuthority role: roles) {
permissions.addAll(getPermissionsIncludedInRole(role));
}
return permissions;
}
Of course from here you could apply a lot of optimizations/customizations for your specific requirements.
