I've been working with PDO lately and the answer above is completely right, but I just wanted to document that the following works as well.
$nametosearch = "Tobias";
$conn = new PDO("server", "username", "password");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sth = $conn->prepare("SELECT `id` from `tablename` WHERE `name` = :name");
$sth->bindParam(':name', $nametosearch);
// Or sth->bindParam(':name', $_POST['namefromform']); depending on application
$sth->execute();
Use AFNetworking; Put other parameters in the parameter dictionary and append the image data in form data.
//Upload Image Using AFNetworking

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"error = %@", error);

[strError stringByAppendingString:STR_ERR_MESSAGE];
}];
if(strError.length>0){
return NO;

Keep It Simple Stupid whenever possible.
Adding NODE_PATH

is deprecated and is replaced by adding "baseUrl": "./src"

If you look at the code of %in%
function (x, table) match(x, table, nomatch = 0L) > 0L
then you should be able to write your version of opposite. I use
`%not in%` <- function (x, table) is.na(match(x, table, nomatch=NA_integer_))
Another way is:
function (x, table) match(x, table, nomatch = 0L) == 0L
I think ForkJoinPool and related enhancement to Executor Framework is an important addition in Java 7.

The key is git submodules.
Start reading the Submodules chapter of the Git Community Book or of the Users Manual
Say you have repository PROJECT1, PROJECT2, and MEDIA...
cd /path/to/PROJECT1
git submodule add ssh://path.to.repo/MEDIA
git commit -m "Added Media submodule"
Repeat on the other repo...
Now, the cool thing is, that any time you commit changes to MEDIA, you can do this:
cd /path/to/PROJECT2/MEDIA
git pull
cd ..
git add MEDIA
git commit -m "Upgraded media to version XYZ"
This just recorded the fact that the MEDIA submodule WITHIN PROJECT2 is now at version XYZ.
It gives you 100% control over what version of MEDIA each project uses. git submodules are great, but you need to experiment and learn about them.
With great power comes the great chance to get bitten in the rump.
$(document).on('keyup','#search_product',function(){
$( "#search_product" ).autocomplete({
source:function(request,response){
$.post("<?= base_url('ecommerce/autocomplete') ?>",{'name':$( "#search_product" ).val()}).done(function(data, status){
response(JSON.parse(data));
});
}
});
});
PHP code :
public function autocomplete(){
$name=$_POST['name'];
$result=$this->db->select('product_name,sku_code')->like('product_name',$name)->get('product_list')->result_array();
$names=array();
foreach($result as $row){
$names[]=$row['product_name'];
}
echo json_encode($names);
}
You can also pass in a variable and/or object if you wanted to.
var str1:String = "John"
var str2:String = "Bob"
var myArray = ["Steve", "Bill", "Linus", "Bret"]
//add to the end of the array with append
myArray.append(str1)
myArray.append(str2)
To add them to the front:
//use 'insert' instead of append
myArray.insert(str1, atIndex:0)
myArray.insert(str2, atIndex:0)
//Swift 3
myArray.insert(str1, at: 0)
myArray.insert(str2, at: 0)
As others have already stated, you can no longer use '+=' as of xCode 6.1
Depending on what you want to compare the stash with (local working tree / parent commit / head commit), there are actually several commands available, amongst which the good old git diff
, and the more specific git stash show
:
+--------------------------------------------------------------------------+
¦ Compare stash with ? ¦ git diff ¦ git stash show ¦
¦----------------------+-------------------------------+-------------------¦
¦ Local working tree ¦ git diff stash@{0} ¦ git stash show -l ¦
¦----------------------¦-------------------------------¦-------------------¦
¦ Parent commit ¦ git diff stash@{0}^ stash@{0} ¦ git stash show -p ¦
¦----------------------¦-------------------------------¦-------------------¦
¦ HEAD commit ¦ git diff stash@{0} HEAD ¦ / ¦
+--------------------------------------------------------------------------+
While git stash show
looks more user friendly on first sight, git diff
is actually more powerful in that it allows specifying filenames for a more focused diff. I've personally set up aliases for all of these commands in my zsh git plugin.
Try this very simple approach:
/*make sure that value is included in the options value of the dropdownlist
e.g.
(<select><option value='CA'>California</option><option value='AK'>Alaska</option> </select>)
*/
$('#mycontrolId').val(myvalue).attr("selected", "selected");
^[a-zA-Z]
means any a-z or A-Z at the start of a line
[^a-zA-Z]
means any character that IS NOT a-z OR A-Z
SELECT ID
FROM A
WHERE ID NOT IN (
SELECT ID
FROM B);
SELECT ID
FROM A a
WHERE NOT EXISTS (
SELECT 1
FROM B b
WHERE b.ID = a.ID)
SELECT a.ID
FROM A a
LEFT OUTER JOIN B b
ON a.ID = b.ID
WHERE b.ID IS NULL
DELETE
FROM A
WHERE ID NOT IN (
SELECT ID
FROM B)
The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.
HTML
<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
Nothing here
</div>
You can use CSS to style the main section of the dialog but not the title
.custom-ui-widget-header-warning {
background: #EBCCCC;
font-size: 1em;
}
You need some JS to style the title
$(function() {
$("#nonmodal1").dialog({
minWidth: 400,
minHeight: 'auto',
autoOpen: false,
dialogClass: 'custom-ui-widget-header-warning',
position: {
my: 'center',
at: 'left'
}
});
$("#dialog1").click(function() {
if ($("#nonmodal1").dialog("isOpen") === true) {
$("#nonmodal1").dialog("close");
} else {
$("#nonmodal1").dialog("open").prev().css('background','#D9534F');
}
});
});
The example only shows simple styling (background) but you can make it as complex as you wish.
You can see it in action here:
I was facing the same problem and I tried using JsonSetting to ignore the self-referencing error its kinda work until I got a class which self-referencing very deeply and my dot-net process hangs on Json writing value.
My Problem
public partial class Company : BaseModel
{
public Company()
{
CompanyUsers = new HashSet<CompanyUser>();
}
public string Name { get; set; }
public virtual ICollection<CompanyUser> CompanyUsers { get; set; }
}
public partial class CompanyUser
{
public int Id { get; set; }
public int CompanyId { get; set; }
public int UserId { get; set; }
public virtual Company Company { get; set; }
public virtual User User { get; set; }
}
public partial class User : BaseModel
{
public User()
{
CompanyUsers = new HashSet<CompanyUser>();
}
public string DisplayName { get; set; }
public virtual ICollection<CompanyUser> CompanyUsers { get; set; }
}
You can see the problem in User class it's referencing to CompanyUser class which is a self-referencing.
Now, I'm calling the GetAll Method which includes all the relational properties.
cs.GetAll("CompanyUsers", "CompanyUsers.User");
On this stage my DotNetCore process hangs on Executing JsonResult, writing value ... and never come. In my Startup.cs, I've already set the JsonOption. For some reason EFCore is including nested property which I'm not asking Ef to give.
options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
expected behavior should be this
Hey EfCore can you please include "CompanyUsers" data as well in my Company class so that i can easily access the data.
then
Hey EfCore can you also please include the "CompanyUsers.User" data as well so that i can easily access the data like this Company.CompanyUsers.First().User.DisplayName
at this stage i should only get this "Company.CompanyUsers.First().User.DisplayName" and it should not give me Company.CompanyUsers.First().User.CompanyUsers which causing the self-referencing issue; Technically it shouldn't give me User.CompanyUsers as CompanyUsers is a navigational property. But, EfCore get very excited and giving me User.CompanyUsers.
So, I decided to write an extension method for property to be excluded from the object (it's actually not excluding it's just setting the property to null). Not only that it will also work on array properties as well. below is the code I'm also going to export the nuget package for other users (not sure if this even helps someone). Reason is simple because I'm too lazy to write .Select(n => new { n.p1, n.p2}); I just don't want to write select statement to exclude only 1 property!
This is not the best code (I'll update at some stage) as I have written in a hurry and though this might help someone who wants to exclude (set null) in the object with arrays also.
public static class PropertyExtensions
{
public static void Exclude<T>(this T obj, Expression<Func<T, object>> expression)
{
var visitor = new PropertyVisitor<T>();
visitor.Visit(expression.Body);
visitor.Path.Reverse();
List<MemberInfo> paths = visitor.Path;
Action<List<MemberInfo>, object> act = null;
int recursiveLevel = 0;
act = (List<MemberInfo> vPath, object vObj) =>
{
// set last propert to null thats what we want to avoid the self-referencing error.
if (recursiveLevel == vPath.Count - 1)
{
if (vObj == null) throw new ArgumentNullException("Object cannot be null");
vObj.GetType().GetMethod($"set_{vPath.ElementAt(recursiveLevel).Name}").Invoke(vObj, new object[] { null });
return;
}
var pi = vObj.GetType().GetProperty(vPath.ElementAt(recursiveLevel).Name);
if (pi == null) return;
var pv = pi.GetValue(vObj, null);
if (pi.PropertyType.IsArray || pi.PropertyType.Name.Contains("HashSet`1") || pi.PropertyType.Name.Contains("ICollection`1"))
{
var ele = (IEnumerator)pv.GetType().GetMethod("GetEnumerator").Invoke(pv, null);
while (ele.MoveNext())
{
recursiveLevel++;
var arrItem = ele.Current;
act(vPath, arrItem);
recursiveLevel--;
}
if (recursiveLevel != 0) recursiveLevel--;
return;
}
else
{
recursiveLevel++;
act(vPath, pv);
}
if (recursiveLevel != 0) recursiveLevel--;
};
// check if the root level propert is array
if (obj.GetType().IsArray)
{
var ele = (IEnumerator)obj.GetType().GetMethod("GetEnumerator").Invoke(obj, null);
while (ele.MoveNext())
{
recursiveLevel = 0;
var arrItem = ele.Current;
act(paths, arrItem);
}
}
else
{
recursiveLevel = 0;
act(paths, obj);
}
}
public static T Explode<T>(this T[] obj)
{
return obj.FirstOrDefault();
}
public static T Explode<T>(this ICollection<T> obj)
{
return obj.FirstOrDefault();
}
}
above extension class will give you the ability to set the property to null to avoid the self-referencing loop even arrays.

{
if (!(node.Member is PropertyInfo))
{
throw new ArgumentException("The path can only contain properties", nameof(node));

Cases:
Case 1: Exclude only property without any array
p.Exclude(n => n.AddressDetail.CountryDetail.CountryName);
Case 2: Exclude property with 1 array
p1.Exclude(n => n.AddressDetail.CountryDetail2.Explode().CountryName);
Case 3: Exclude property with 2 nested array
p1.Exclude(n => n.AddressDetail.CountryDetail2.Explode().CountryDetail.Explode().Name);
Case 4: EF GetAll Query With Includes
var query = cs.GetAll("CompanyUsers", "CompanyUsers.User").ToArray();
query.Exclude(n => n.Explode().CompanyUsers.Explode().User.CompanyUsers);
return query;
You have notice that Explode() method its also a extension method just for our expression builder to get the property from array property. Whenever there is a array property use the .Explode().YourPropertyToExclude or .Explode().Property1.MyArrayProperty.Explode().MyStupidProperty. Above code helps me to avoid the self-referencing so deep as deep i want. Now i can use GetAll and exclude the property which i don;t want!
Thank you for reading this big post!
The string has a substring method that returns the string at the specified position.
String name="123456789";
System.out.println(name.substring(0,1));
None of the answers solved exactly my problem (the solution file I was running was trying to find xcopy to copy a dll after generation).
What solved it for me was going into menu "Project -> Properties"
Then in the window that opens choosing on the left pane: "Configuration Properties -> VC++ Directories
On the right pane under "General" choosing "Executable Directories "
And then adding:
$(SystemRoot)\system32;$(SystemRoot);$(SystemRoot)\System32\Wbem;$(SystemRoot)\System32\WindowsPowerShell\v1.0\;$(ExecutablePath)
None of these answers were sufficient for me, using Jenkins CI v.1.555, Git Client plugin v.1.6.4, and Git plugin 2.0.4.
I wanted a job to build for one Git repository for one specific, fixed (i.e., non-parameterized) tag. I had to cobble together a solution from the various answers plus the "build a Git tag" blog post cited by Thilo.
git push --tags
+refs/tags/*:refs/remotes/origin/tags/*
*/tags/<TAG_TO_BUILD>
(replacing <TAG_TO_BUILD>
with your actual tag name).Adding the Refspec for me turned out to be critical. Although it seemed the git repositories were fetching all the remote information by default when I left it blank, the Git plugin would nevertheless completely fail to find my tag. Only when I explicitly specified "get the remote tags" in the Refspec field was the Git plugin able to identify and build from my tag.
Update 2014-5-7: Unfortunately, this solution does come with an undesirable side-effect for Jenkins CI (v.1.555) and the Git repository push notification mechanism à la Stash Webhook to Jenkins: any time any branch on the repository is updated in a push, the tag build jobs will also fire again. This leads to a lot of unnecessary re-builds of the same tag jobs over and over again. I have tried configuring the jobs both with and without the "Force polling using workspace" option, and it seemed to have no effect. The only way I could prevent Jenkins from making the unnecessary builds for the tag jobs is to clear the Refspec field (i.e., delete the +refs/tags/*:refs/remotes/origin/tags/*
).
If anyone finds a more elegant solution, please edit this answer with an update. I suspect, for example, that maybe this wouldn't happen if the refspec specifically was +refs/tags/<TAG TO BUILD>:refs/remotes/origin/tags/<TAG TO BUILD>
rather than the asterisk catch-all. For now, however, this solution is working for us, we just remove the extra Refspec after the job succeeds.
Recursion is used in things like BSP trees for collision detection in game development (and other similar areas).
Html.Action is a poorly designed technology. Because in your page Controller you can't receive the results of computation in your Partial Controller. Data flow is only Page Controller => Partial Controller.
To be closer to WebForm UserControl (*.ascx) you need to:
Create a page Model and a Partial Model
Place your Partial Model as a property in your page Model
In this situation you can use it like:
public class MyController : Controller
{
....
public MyController()
{
MyChildController = new MyControllerPartial(this.ViewData);
}
[HttpPost]
public ActionResult Index(MyPageViewModel model)
{
...
int childResult = MyChildController.ProcessSomething(model.MyPartialModel);
...
}
}
P.S. In step 3 you can use Html.Partial("PartialViewName", Model.MyPartialModel, <clone_ViewData_with_prefix_MyPartialModel>). For more details see ASP.NET MVC partial views: input name prefixes
Implicit declarations are not valid in C.
C99 removed this feature (present in C89).
gcc
chooses to only issue a warning by default with -std=c99
but a compiler has the right to refuse to translate such a program.
Only thing that worked for me is this function:
Sub DoTrim()
Dim cell As Range
Dim str As String
For Each cell In Selection.Cells
If cell.HasFormula = False Then
str = Left(cell.Value, 1) 'space
While str = " " Or str = Chr(160)
cell.Value = Right(cell.Value, Len(cell.Value) - 1)
str = Left(cell.Value, 1) 'space
Wend
str = Right(cell.Value, 1) 'space
While str = " " Or str = Chr(160)
cell.Value = Left(cell.Value, Len(cell.Value) - 1)
str = Right(cell.Value, 1) 'space
Wend
End If
Next cell
End Sub
You can try the keyword use
in Closure functions or Lambdas if this fits your intention... PHP 7.0 though. Not that's its better, but just an alternative.
$foo = "New";
$closure = (function($bar) use ($foo) {
echo "$foo $bar";
})("York");
Service references are another example where partial classes are useful to separate generated code from user-created code.
You can "extend" the service classes without having them overwritten when you update the service reference.
I made an experiment using the magic method __call. Not sure if I should post it (because of all the "DO NOT USE MAGIC METHODS" warnings in the other answers and comments) but i'll leave it here.. just in case someone find it useful.
public function __call($_name, $_arguments){
$action = substr($_name, 0, 4);
$varName = substr($_name, 4);
if (isset($this->{$varName})){
if ($action === "get_") return $this->{$varName};
if ($action === "set_") $this->{$varName} = $_arguments[0];
}
}
Just add that method above in your class, now you can type:
class MyClass{
private foo = "bar";
private bom = "bim";
// ...
// public function __call(){ ... }
// ...
}
$C = new MyClass();
// as getter
$C->get_foo(); // return "bar"
$C->get_bom(); // return "bim"
// as setter
$C->set_foo("abc"); // set "abc" as new value of foo
$C->set_bom("zam"); // set "zam" as new value of bom
This way you can get/set everything in your class if it exist so, if you need it for only a few specific elements, you could use a "whitelist" as filter.
Example:
private $callWhiteList = array(
"foo" => "foo",
"fee" => "fee",
// ...
);
public function __call($_name, $_arguments){
$action = substr($_name, 0, 4);
$varName = $this->callWhiteList[substr($_name, 4)];
if (!is_null($varName) && isset($this->{$varName})){
if ($action === "get_") return $this->{$varName};
if ($action === "set_") $this->{$varName} = $_arguments[0];
}
}
Now you can only get/set "foo" and "fee".
You can also use that "whitelist" to assign custom names to access to your vars.
For example,
private $callWhiteList = array(
"myfoo" => "foo",
"zim" => "bom",
// ...
);
With that list you can now type:
class MyClass{
private foo = "bar";
private bom = "bim";
// ...
// private $callWhiteList = array( ... )
// public function __call(){ ... }
// ...
}
$C = new MyClass();
// as getter
$C->get_myfoo(); // return "bar"
$C->get_zim(); // return "bim"
// as setter
$C->set_myfoo("abc"); // set "abc" as new value of foo
$C->set_zim("zam"); // set "zam" as new value of bom
.
.
.
That's all.
Doc: __call() is triggered when invoking inaccessible methods in an object context.

or FileWriter
to write back to the file, applying the changes.
I think there is a more efficient way of getting the iterator's position of the scanner at some point, in order to better implement editting. But since files are either open for reading, or writing, I'm not sure regarding that.
In any case, you can use libraries already available for parsing of XML files, which have all of this implemented already and will allow you to do what you want easily.
In fact, it is very easy.
composer update
will do all this for you, but it will also update the other packages.
To remove a package without updating the others, specifiy that package in the command, for instance:
composer update monolog/monolog
will remove the monolog/monolog
package.
Nevertheless, there may remain some empty folders or files that cannot be removed automatically, and that have to be removed manually.

Thanks Attack. I wanted to use jQuery.
You pointed me in the right direction, and this is what I ended up with:
Here is a link to the plugin: https://plugins.jquery.com/textfill/
And a link to the source: http://jquery-textfill.github.io/
;(function($) {
$.fn.textfill = function(options) {
var fontSize = options.maxFontPixels;
var ourText = $('span:visible:first', this);
var maxHeight = $(this).height();
var maxWidth = $(this).width();
var textHeight;
var textWidth;
do {
ourText.css('font-size', fontSize);
textHeight = ourText.height();
textWidth = ourText.width();
fontSize = fontSize - 1;
} while ((textHeight > maxHeight || textWidth > maxWidth) && fontSize > 3);
return this;
}
})(jQuery);
$(document).ready(function() {
$('.jtextfill').textfill({ maxFontPixels: 36 });
});
and my html is like this
<div class='jtextfill' style='width:100px;height:50px;'>
<span>My Text Here</span>
</div>
This is my first jquery plugin, so it's probably not as good as it should be. Pointers are certainly welcome.
This solution will help to calculate the height and width at runtime.
let messageText = "Your Text String"
let size = CGSize.init(width: 250, height: 1000)
let options = NSStringDrawingOptions.usesFontLeading.union(.usesLineFragmentOrigin)
let estimateFrame = NSString(string: messageText).boundingRect(with: size, options: options, attributes: [NSAttributedString.Key.font: UIFont(name: "HelveticaNeue", size: 17)!], context: nil)
Here you can calculate the estimated height that your string would take and pass it to the UILabel frame.
estimateFrame.Width
estimateFrame.Height
To get all the artisan command, type...
php artisan
If you want to clear view cache, just use:
php artisan view:clear
If you don't know how to use specific artisan command, just add "help" (see below)

Add something like this to it:
Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y"
And then use it the following way:

Have you tried the SVG text element?
.append("text").text(function(d, i) { return d[whichevernode];})
rect element doesn't permit text element inside of it. It only allows descriptive elements (<desc>, <metadata>, <title>
) and animation elements (<animate>, <animatecolor>, <animatemotion>, <animatetransform>, <mpath>, <set>
)
Append the text element as a sibling and work on positioning.
UPDATE
Using g grouping, how about something like this? fiddle
You can certainly move the logic to a CSS class you can append to, remove from the group (this.parentNode)
You can use
Trace.WriteLine()
to write to the Output window when debugging a unit test.
You can do this a couple of ways:
Use the -w option to change the working directory:
-w, --workdir="" Working directory inside the container
https://docs.docker.com/engine/reference/commandline/run/#set-working-directory--w
Pass the entire argument to /bin/bash:
docker run image /bin/bash -c "cd /path/to/somewhere; python a.py"
For the simple answer, you can use Link
component from react-router
, instead of button
. There is ways to change the route in JS, but seems you don't need that here.
<span className="input-group-btn">
<Link to="/login" />Click to login</Link>
</span>
To do it programmatically in 1.0.x, you do like this, inside your clickHandler function:
this.history.pushState(null, 'login');
Taken from upgrade doc here
You should have this.history
placed on your route handler component by react-router
. If it child component beneath that mentioned in routes
definition, you may need pass that down further

.table-vcenter {
td,
th {

Contrary to what pointy says, the blur()
method does exist and is a part of the w3c standard. The following exaple will work in every modern browser (including IE):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Javascript test</title>
<script type="text/javascript" language="javascript">
window.onload = function()
{
var field = document.getElementById("field");
var link = document.getElementById("link");
var output = document.getElementById("output");
field.onfocus = function() { output.innerHTML += "<br/>field.onfocus()"; };
field.onblur = function() { output.innerHTML += "<br/>field.onblur()"; };
link.onmouseover = function() { field.blur(); };
};
</script>
</head>
<body>
<form name="MyForm">
<input type="text" name="field" id="field" />
<a href="javascript:void(0);" id="link">Blur field on hover</a>
<div id="output"></div>
</form>
</body>
</html>
Note that I used link.onmouseover
instead of link.onclick
, because otherwise the click itself would have removed the focus.
Since you're using knockout, you should consider using the knockout utility function arrayMap()
and it's other array utility functions.
Here's a listing of array utility functions and their equivalent LINQ methods:
arrayFilter() -> Where()
arrayFirst() -> First()
arrayForEach() -> (no direct equivalent)
arrayGetDistictValues() -> Distinct()
arrayIndexOf() -> IndexOf()
arrayMap() -> Select()
arrayPushAll() -> (no direct equivalent)
arrayRemoveItem() -> (no direct equivalent)
compareArrays() -> (no direct equivalent)
So what you could do in your example is this:
var mapped = ko.utils.arrayMap(selectedFruits, function (fruit) {
return fruit.id;
});
If you want a LINQ like interface in javascript, you could use a library such as linq.js which offers a nice interface to many of the LINQ methods.
var mapped = Enumerable.From(selectedFruits)
.Select("$.id") // 1 of 3 different ways to specify a selector function
.ToArray();
There is a modern API dedicated for this purpose - Broadcast Channel
It is as easy as:
var bc = new BroadcastChannel('test_channel');
bc.postMessage('This is a test message.'); /* send */
bc.onmessage = function (ev) { console.log(ev); } /* receive */
There is no need for the message to be just a DOMString, any kind of object can be sent.
Probably, apart from API cleanness, it is the main benefit of this API - no object stringification.
Currently supported only in Chrome and Firefox, but you can find a polyfill that uses localStorage.
You see the two empty -D
entries in the g++
command line? They're causing the problem. You must have values in the -D
items e.g. -DWIN32
if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:
SYSTEM ?= generic
ENVIRONMENT ?= generic
in the makefile which gives them default values.
Your output looks to be missing the all important output:
<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers
just to clarify, what actually got sent to g++
was -D -DWindows_NT
, i.e. define a preprocessor macro called -DWindows_NT
; which is of course not a valid identifier (similarly for -D -I.
)
Combining two byte[]
using iTextSharp up to version 5.x:
internal static MemoryStream mergePdfs(byte[] pdf1, byte[] pdf2)
{
MemoryStream outStream = new MemoryStream();
using (Document document = new Document())
using (PdfCopy copy = new PdfCopy(document, outStream))
{
document.Open();
copy.AddDocument(new PdfReader(pdf1));
copy.AddDocument(new PdfReader(pdf2));
}
return outStream;
}
Instead of the byte[]
's it's possible to pass also Stream
's
For me the problem was tied to having the same file included in the bundle resources twice. Not sure how that happened, but I removed one of them and it compiled fine with the new build system.
Well yes, the access exception is due to the fact that document.domain
must match in your parent and your iframe, and before they do, you won't be able to programmatically set the document.domain
property of your iframe.
I think your best option here is to point the page to a template of your own:
iframe.src = '/myiframe.htm#' + document.domain;
And in myiframe.htm:
document.domain = location.hash.substring(1);
Logically there are no difference at all. Performance-wise there are -typically, on most DBMSes- no difference at all.
This is a common question. In base, the option you're looking for is aggregate
. Assuming your data.frame
is called "mydf", you can use the following.
> aggregate(B ~ A, mydf, sum)
A B
1 1 5
2 2 3
3 3 11
I would also recommend looking into the "data.table" package.
> library(data.table)
> DT <- data.table(mydf)
> DT[, sum(B), by = A]
A V1
1: 1 5
2: 2 3
3: 3 11
I think it's first worth noting that without javascript (plain html), the form
element submits when clicking either the <input type="submit" value="submit form">
or <button>submits form too</button>
. In javascript you can prevent that by using an event handler and calling e.preventDefault()
on button click, or form submit. e
is the event object passed into the event handler. With react, the two relevant event handlers are available via the form as onSubmit
, and the other on the button via onClick
.
Example: http://jsbin.com/vowuley/edit?html,js,console,output
const format1 = "YYYY-MM-DD HH:mm:ss"
const format2 = "YYYY-MM-DD"
var date1 = new Date("2020-06-24 22:57:36");
var date2 = new Date();
dateTime1 = moment(date1).format(format1);
dateTime2 = moment(date2).format(format2);
document.getElementById("demo1").innerHTML = dateTime1;
document.getElementById("demo2").innerHTML = dateTime2;
_x000D_
<!DOCTYPE html>
<html>
<body>

This is a bad way of doing it, but it worked for me when trying to interpret escaped octals passed in a string argument.
input_string = eval('b"' + sys.argv[1] + '"')
It's worth mentioning that there is a difference between eval and ast.literal_eval (eval being way more unsafe). See Using python's eval() vs. ast.literal_eval()?
I finally solved this myself. If anyone else is having this problem, here is my solution:
I created a new method:
public function curl_del($path)
{
$url = $this->__url.$path;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
$result = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return $result;
}
Update 2
Since this seems to help some people, here is my final curl DELETE method, which returns the HTTP response in JSON decoded object:
/**
* @desc Do a DELETE request with cURL
*
* @param string $path path that goes after the URL fx. "/user/login"
* @param array $json If you need to send some json with your request.
* For me delete requests are always blank
* @return Obj $result HTTP response from REST interface in JSON decoded.
*/
public function curl_del($path, $json = '')
{
$url = $this->__url.$path;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$result = json_decode($result);
curl_close($ch);
return $result;
}
Jenkins stores some of the related builds data like the following:
The working directory is stored in the directory {JENKINS_HOME}/workspace/

{JENKINS_HOME}/workspace/{JOBNAME}
The configuration for all jobs stored in the directory {JENKINS_HOME}/jobs/
.
Each job store its related builds data in the directory
{JENKINS_HOME}/jobs/{JOBNAME}
Each job folder contains:
The job configuration file is {JENKINS_HOME}/jobs/{JOBNAME}/config.xml
The job builds are stored in {JENKINS_HOME}/jobs/{JOBNAME}/builds/
See the Jenkins documentation for a visual representation and further details.

i find best for do it fast and simple
find ur item in list
var d = Details.Where(x => x.ProductID == selectedProduct.ID).SingleOrDefault();
make clone from current
OrderDetail dd = d;
Update ur clone
dd.Quantity++;
find index in list
int idx = Details.IndexOf(d);
remove founded item in (1)
Details.Remove(d);
insert
if (idx > -1)
Details.Insert(idx, dd);
else
Details.Insert(Details.Count, dd);
I found this interesting though
if ( $value + 0 eq $value) {
# A number
push @args, $value;
} else {
# A string
push @args, "'$value'";
}

With this code you will be also able to get MacAddress in Android 6.0 also
public static String getMacAddr() {
try {
List <NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
for (NetworkInterface nif: all) {
if (!nif.getName().equalsIgnoreCase("wlan0")) continue;
byte[] macBytes = nif.getHardwareAddress();
if (macBytes == null) {
return "";
}
StringBuilder res1 = new StringBuilder();
for (byte b: macBytes) {
//res1.append(Integer.toHexString(b & 0xFF) + ":");
res1.append(String.format("%02X:", b));
}
if (res1.length() > 0) {
res1.deleteCharAt(res1.length() - 1);
}
return res1.toString();
}
} catch (Exception ex) {}
return "02:00:00:00:00:00";
}
EDIT 1. This answer got a bug where a byte that in hex form got a single digit, will not appear with a "0" before it. The append to res1 has been changed to take care of it.
Though this isn't a DIRECT answer to your question, I just encountered a similar problem, and thought I'd mentioned it:
I had an instance where it was instantiating a new (no doubt very inefficent) record for data.frame (a result of recursive searching) and it was giving me the same error.
I had this:
return(
data.frame(
user_id = gift$email,
sourced_from_agent_id = gift$source,
method_used = method,
given_to = gift$account,
recurring_subscription_id = NULL,
notes = notes,
stringsAsFactors = FALSE
)
)
turns out... it was the = NULL. When I switched to = NA, it worked fine. Just in case anyone else with a similar problem hits THIS post as I did.

All you guys need to learn to navigate with tools that predate GPS. Something like a sextant, octant, backstaff or an astrolabe.
If you have receive the signal from 3 different locations then you only need to measure the signal strength and make a ratio from those locations. Simple triangle calculation where a2+b2=c2. The stronger the signal strength the closer the device is to the receiver.

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str())

Actually, none of these answers reflect current state of the art with Git (v2.29 by time of writing this answer). In the latest versions of Git, cache
, winstore
, wincred
are deprecated.
If you want to clone a Bitbucket repository via HTTPS, e.g.
git clone https://[email protected]/SomeOrganization/SomeRepo.git
.gitconfig
accordingly (global or local)[credential]
helper = manager
You can locate your .gitconfig
by executing this command.
git config --list --show-origin
git clone https://[email protected]/SomeOrganization/SomeRepo.git
and wait until log on window appears. Use your user name from the url (kutlime in my case) and your generated app password as a password.
The dat file has some lines of extra information before the actual data. Skip them with the skip
argument:
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)
An easy way to check this if you are unfamiliar with the dataset is to first use readLines
to check a few lines, as below:
readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
n=10)
# [1] "Ozone data from CZ03 2009" "Local time: GMT + 0"
# [3] "" "Date Hour Value"
# [5] "01.01.2009 00:00 34.3" "01.01.2009 01:00 31.9"
# [7] "01.01.2009 02:00 29.9" "01.01.2009 03:00 28.5"
# [9] "01.01.2009 04:00 32.9" "01.01.2009 05:00 20.5"
Here, we can see that the actual data starts at [4]
, so we know to skip the first three lines.
If you really only wanted the Value
column, you could do that by:
as.vector(
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)$Value)
Again, readLines
is useful for helping us figure out the actual name of the columns we will be importing.
But I don't see much advantage to doing that over reading the whole dataset in and extracting later.
I'm doing in this way and it works .
HttpHeaders headers = createHttpHeaders(map);
public HttpHeaders createHttpHeaders(Map<String, String> map)
{
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
for (Entry<String, String> entry : map.entrySet()) {
headers.add(entry.getKey(),entry.getValue());
}
return headers;
}
// Pass headers here
String requestJson = "{ // Construct your JSON here }";
logger.info("Request JSON ="+requestJson);
HttpEntity<String> entity = new HttpEntity<String>(requestJson, headers);
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);
logger.info("Result - status ("+ response.getStatusCode() + ") has body: " + response.hasBody());
logger.info("Response ="+response.getBody());
Hope this helps
You can use underscore.js : http://underscorejs.org/#intersection
You have needed methods for array :
_.difference([1, 2, 3, 4, 5], [5, 2, 10]);
=> [1, 3, 4]
_.intersection([1, 2, 3], [101, 2, 1, 10], [2, 1]);
=> [1, 2]
Use crontab to add job
crontab -e
And job should be in this format:
00 19 * * 1,3,5 /home/user/somejob.sh
Works Fine. Try this,
private void addImageButton_Click(object sender, EventArgs e)
{
OpenFileDialog of = new OpenFileDialog();
//For any other formats
of.Filter = "Image Files (*.bmp;*.jpg;*.jpeg,*.png)|*.BMP;*.JPG;*.JPEG;*.PNG";
if (of.ShowDialog() == DialogResult.OK)
{
pictureBox1.ImageLocation = of.FileName;
}
}
One option:
run git gc
manually to condense a number of pack files into one or a few pack files.
This operation is persistent (i.e. the large pack file will retain its compression behavior) so it may be beneficial to compress a repository periodically with git gc --aggressive
Another option is to save the code and .git somewhere and then delete the .git and start again using this existing code, creating a new git repository (git init
).
Assuming the application you are attempting to run in the background is CLI based, you can try calling the scheduled jobs using Hidden Start

Here's what I do. I find the minimum first then after the minimum is found, it is removed from ArrayList.
ArrayList<Integer> a = new ArrayList<>();
a.add(3);
a.add(6);
a.add(2);
a.add(5);
while (a.size() > 0) {
int min = 1000;
for (int b:a) {
if (b < min)
min = b;
}
System.out.println("minimum: " + min);
System.out.println("index of min: " + a.indexOf((Integer) min));
a.remove((Integer) min);
}
Well, this one liner might qualify (uses Guava Ranges)
ContiguousSet<Integer> integerList = ContiguousSet.create(Range.closedOpen(0, 10), DiscreteDomain.integers());
System.out.println(integerList);
This doesn't create a List<Integer>
, but ContiguousSet
offers much the same functionality, in particular implementing Iterable<Integer>
which allows foreach
implementation in the same way as List<Integer>
.
In older versions (somewhere before Guava 14) you could use this:
ImmutableList<Integer> integerList = Ranges.closedOpen(0, 10).asSet(DiscreteDomains.integers()).asList();
System.out.println(integerList);
Both produce:
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
I do not remember from where I copied this function, but it looks like it is not listed and it is working for me
function rm_rf($path) {
if (@is_dir($path) && is_writable($path)) {
$dp = opendir($path);
while ($ent = readdir($dp)) {
if ($ent == '.' || $ent == '..') {
continue;
}
$file = $path . DIRECTORY_SEPARATOR . $ent;
if (@is_dir($file)) {
rm_rf($file);
} elseif (is_writable($file)) {
unlink($file);
} else {
echo $file . "is not writable and cannot be removed. Please fix the permission or select a new path.\n";
}
}
closedir($dp);
return rmdir($path);
} else {
return @unlink($path);
}
}
It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?
Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:
UPDATE INVOICE
SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
, INV_TOTAL = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)
WHERE INV_ID = I_INV_ID;
Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.
Use Window.location.href to take the url in javascript. it's a property that will tell you the current URL location of the browser. Setting the property to something different will redirect the page.
if (window.location.href.indexOf('franky') > -1) {
alert("your url contains the name franky");
}
I know this is an old question, but looking at the original question, it looks like the user just wanted to run a command as root, that's what I need to do when I was searching for an answer and stumbled across the question.
So this one is worth knowing in my opinion:
vagrant ssh servername -c "echo vagrant | sudo -S shutdown 0"
vagrant
is the password being echoed into the the sudo command, because as we all know, the vagrant account has sudo privileges and when you sudo, you need to specify the password of the user account, not root..and of course by default, the vagrant user's password is vagrant
!
By default you need root privileges to shutdown so I guess doing a shutdown is a good test.
Obviously you don't need to specify a server name if there is only one for that vagrant environment. Also, we're talking about local vagrant virtual machine to the host, so there isn't really any security issue that I can see.
Hope this helps.
For me issue is resolved by changing envs like this:
env.put("LDAP_BASEDN", base)
env.put(Context.SECURITY_PRINCIPAL,"user@domain")
If you go here you can find a comprehensive matrix that includes both the NLog and Log4Net libs as well as Enterprise Lib and other products.
Somebody could argue that the matrix is done in a way to underline the features of the only commercial lib present in the matrix. I think it's true but it was useful anyway to drive my choice versus NLog.

One thing you could do would be to create a dictionary. Might be a little sloppy considering your looking for 64 elements but it gets the job done. Im not sure if its the "preferred way" to do it but it worked for me using an array of structs.

You can use a web-service from http://ip-api.com
in your php code, do as follow :
<?php
$ip = $_REQUEST['REMOTE_ADDR']; // the IP address to query
$query = @unserialize(file_get_contents('http://ip-api.com/php/'.$ip));
if($query && $query['status'] == 'success') {
echo 'Hello visitor from '.$query['country'].', '.$query['city'].'!';
} else {
echo 'Unable to get location';
}
?>
the query have many other informations:
array (
'status' => 'success',
'country' => 'COUNTRY',
'countryCode' => 'COUNTRY CODE',
'region' => 'REGION CODE',
'regionName' => 'REGION NAME',
'city' => 'CITY',
'zip' => ZIP CODE,
'lat' => LATITUDE,
'lon' => LONGITUDE,
'timezone' => 'TIME ZONE',
'isp' => 'ISP NAME',
'org' => 'ORGANIZATION NAME',
'as' => 'AS NUMBER / NAME',
'query' => 'IP ADDRESS USED FOR QUERY',
)
kubectl exec -it POD_NAME -c CONTAINER_NAME bash - then kill 1
Assuming the container is run as root which is not recommended.
In my case when I changed the application config, I had to reboot the container which was used in a sidecar pattern, I would kill the PID for the spring boot application which is owned by the docker user.
This is an example to read and write binary jjpg or wmv video file. FILE *fout; FILE *fin;
Int ch;
char *s;
fin=fopen("D:\\pic.jpg","rb");
if(fin==NULL)
{ printf("\n Unable to open the file ");
exit(1);
}
fout=fopen("D:\\ newpic.jpg","wb");
ch=fgetc(fin);
while (ch!=EOF)
{
s=(char *)ch;
printf("%c",s);
ch=fgetc (fin):
fputc(s,fout);
s++;
}
printf("data read and copied");
fclose(fin);
fclose(fout);
I will rename variables to reduce confusion. n -> nf or nmain. x -> xf or xmain:
def f(nf, xf):
nf = 2
xf.append(4)
print 'In f():', nf, xf
def main():
nmain = 1
xmain = [0,1,2,3]
print 'Before:', nmain, xmain
f(nmain, xmain)
print 'After: ', nmain, xmain
main()
When you call the function f, the Python runtime makes a copy of xmain and assigns it to xf, and similarly assigns a copy of nmain to nf.
In the case of n, the value that is copied is 1.
In the case of x the value that is copied is not the literal list [0, 1, 2, 3]. It is a reference to that list. xf and xmain are pointing at the same list, so when you modify xf you are also modifying xmain.
If, however, you were to write something like:
xf = ["foo", "bar"]
xf.append(4)
you would find that xmain has not changed. This is because, in the line xf = ["foo", "bar"] you have change xf to point to a new list. Any changes you make to this new list will have no effects on the list that xmain still points to.
Hope that helps. :-)
Application pools are used to separate set of IIS worker processes that share the same configuration. Application pools enable us to isolate our web application for better security, reliability, and availability
Ah I think a understand now. Have a look if this really is what you want:
$(".start").keyup(function(){
$(this).closest('tr').find("input").each(function() {
alert(this.value)
});
});
This will give you all input values of a row.
Update:
To get the value of not all elements you can use :not()
:
$(this).closest('tr').find("input:not([name^=desc][name^=phone])").each(function() {
alert(this.value)
});
Actually I am not 100% sure whether it works this way, maybe you have to use two not
s instead of this one combining both conditions.
If you need one item to be left aligned (like a header) but then multiple items right aligned (like 3 images), then you would do something like this:
h1 {
flex-basis: 100%; // forces this element to take up any remaining space
}
img {
margin: 0 5px; // small margin between images
height: 50px; // image width will be in relation to height, in case images are large - optional if images are already the proper size
}
Here's what that will look like (only relavent CSS was included in snippet above)
I am using Debian 8 live off a USB. I was locked out of the system after 10 min of inactivity. The password that was required to log back in to the system for the user was:
login : Debian Live User
password : live
I hope this helps
Beware of recipes like this
target:
MY_ID=$(GENERATE_ID);
echo $MY_ID;
It does two things wrong. The first line in the recipe is executed in a separate shell instance from the second line. The variable is lost in the meantime. Second thing wrong is that the $
is not escaped.
target:
MY_ID=$(GENERATE_ID); \
echo $$MY_ID;
Both problems have been fixed and the variable is useable. The backslash combines both lines to run in one single shell, hence the setting of the variable and the reading of the variable afterwords, works.
I realize the original post said how to get the results of a shell command into a MAKE variable, and this answer shows how to get it into a shell variable. But other readers may benefit.
One final improvement, if the consumer expects an "environment variable" to be set, then you have to export it.
my_shell_script
echo $MY_ID
would need this in the makefile
target:
export MY_ID=$(GENERATE_ID); \
./my_shell_script;
Hope that helps someone. In general, one should avoid doing any real work outside of recipes, because if someone use the makefile with '--dry-run' option, to only SEE what it will do, it won't have any undesirable side effects. Every $(shell)
call is evaluated at compile time and some real work could accidentally be done. Better to leave the real work, like generating ids, to the inside of the recipes when possible.
If you want to create a temp table after check exist table.You can use the following code
DROP TABLE IF EXISTS tempdb.dbo.#temptable
CREATE TABLE #temptable
(
SiteName NVARCHAR(50),
BillingMonth varchar(10),
Consumption INT,
)
After creating the temporary table, you can insert data into this table as a regular table:
INSERT INTO #temptable
SELECT COLUMN1,...
FROM
(...)
or
INSERT INTO #temptable
VALUES (value1, value2, value3, ...);
The SELECT statement is used to select data from a temp table.
SELECT * FROM #temptable
you can manually remove the temporary table by using the DROP TABLE statement:
DROP TABLE #temptable;

in oninvalid
, change your code with this:
oninvalid="this.setCustomValidity('Lütfen isaretli yerleri doldurunuz')"
<form><input type="text" name="company_name" oninvalid="this.setCustomValidity('Lütfen isaretli yerleri doldurunuz')" required /><input type="submit">_x000D_
</form>
_x000D_
The following should work, but you may need to change the format:
echo date('l F jS, Y (m-d-Y)', strtotime('+3 months', strtotime($DateToAdjust)));
README.md
or .mkdn
or .markdown
denotes that the file is markdown formatted.
Markdown is a markup language. With it you can easily display headers or have italic words, or bold or almost anything that can be done to text
What do you mean, the error only shows up when you assign? For example on GCC, with no assignment in sight:
int main() {
struct blah *b = 0;
*b; // this is line 6
}
incompletetype.c:6: error: dereferencing pointer to incomplete type
.
The error is at line 6, that's where I used an incomplete type as if it were a complete type. I was fine up until then.
The mistake is that you should have included whatever header defines the type. But the compiler can't possibly guess what line that should have been included at: any line outside of a function would be fine, pretty much. Neither is it going to go trawling through every text file on your system, looking for a header that defines it, and suggest you should include that.
Alternatively (good point, potatoswatter), the error is at the line where b
was defined, when you meant to specify some type which actually exists, but actually specified blah
. Finding the definition of the variable b
shouldn't be too difficult in most cases. IDEs can usually do it for you, compiler warnings maybe can't be bothered. It's some pretty heinous code, though, if you can't find the definitions of the things you're using.
If the DLL is of type COM library, then you can use pythonnet.
pip install pythonnet
Then in your python code, try the following
import clr
clr.AddReference('path_to_your_dll')
then instantiate an object as per the class in the DLL, and access the methods within it.
This looks like a CSV file, so you could use the python csv module to read it. For example:
import csv
crimefile = open(fileName, 'r')
reader = csv.reader(crimefile)
allRows = [row for row in reader]
Using the csv module allows you to specify how things like quotes and newlines are handled. See the documentation I linked to above.
$('input[type=file]').val()
That'll get you the file selected.
However, you can't set the value yourself.
sed would be a better choice (stream editor)
tail -n0 -f <file> | sed -n '/search string/p'
and then if you wanted the tail command to exit once you found a particular string:
tail --pid=$(($BASHPID+1)) -n0 -f <file> | sed -n '/search string/{p; q}'
Obviously a bashism: $BASHPID will be the process id of the tail command. The sed command is next after tail in the pipe, so the sed process id will be $BASHPID+1.

I think that the best approach is to assign the onclick handler unobtrusively.
Something like this:
window.onload = function(){
var myLink = document.getElementsById('myLinkId');
myLink.onclick = function(){
parse('#', false, '<a href="xyz');
return false;
}
}
//...
<a href="#" id="myLink">Test</a>
Nicholas Westby provided a great solution in a awesome article.
If you want Deserializing JSON to one of many possible classes that implement an interface like that:
public class Person
{
public IProfession Profession { get; set; }
}
public interface IProfession
{
string JobTitle { get; }
}
public class Programming : IProfession
{
public string JobTitle => "Software Developer";
public string FavoriteLanguage { get; set; }
}
public class Writing : IProfession
{
public string JobTitle => "Copywriter";
public string FavoriteWord { get; set; }
}
public class Samples
{
public static Person GetProgrammer()
{
return new Person()
{
Profession = new Programming()
{
FavoriteLanguage = "C#"
}
};
}
}
You can use a custom JSON converter:
public class ProfessionConverter : JsonConverter
{
public override bool CanWrite => false;
public override bool CanRead => true;
public override bool CanConvert(Type objectType)
{
return objectType == typeof(IProfession);
}
public override void WriteJson(JsonWriter writer,
object value, JsonSerializer serializer)
{
throw new InvalidOperationException("Use default serialization.");
}
public override object ReadJson(JsonReader reader,
Type objectType, object existingValue,
JsonSerializer serializer)
{
var jsonObject = JObject.Load(reader);
var profession = default(IProfession);
switch (jsonObject["JobTitle"].Value())
{
case "Software Developer":
profession = new Programming();
break;
case "Copywriter":
profession = new Writing();
break;
}
serializer.Populate(jsonObject.CreateReader(), profession);
return profession;
}
}
And you will need to decorate the "Profession" property with a JsonConverter attribute to let it know to use your custom converter:
public class Person
{
[JsonConverter(typeof(ProfessionConverter))]
public IProfession Profession { get; set; }
}
And then, you can cast your class with an Interface:
Person person = JsonConvert.DeserializeObject<Person>(jsonString);
I think you can do what you want to do by running the build via a docker command which itself is run inside a docker container. See Docker can now run within Docker | Docker Blog. A technique like this, but which actually accessed the outer docker from with a container, was used, e.g., while exploring how to Create the smallest possible Docker container | Xebia Blog.
Another relevant article is Optimizing Docker Images | CenturyLink Labs, which explains that if you do end up downloading stuff during a build, you can avoid having space wasted by it in the final image by downloading, building and deleting the download all in one RUN step.
No, how you are doing it is correct.

I had a similar issue when calling the WPF window out of WinForms.
var wpfwindow = new ScreenBoardWPF.IzbiraProjekti();
ElementHost.EnableModelessKeyboardInterop(wpfwindow);
wpfwindow.Show();
However, showing window as a dialog, it worked
var wpfwindow = new ScreenBoardWPF.IzbiraProjekti();
ElementHost.EnableModelessKeyboardInterop(wpfwindow);
wpfwindow.ShowDialog();

Compatibility Supports Says that
Under compatibility level 110, the default style for CAST and CONVERT
operations on time
and datetime2
data types is always 121. If your query relies on the old behavior, use a compatibility level less than 110, or explicitly specify the 0 style in the affected query.
That means by default datetime2
is CAST as varchar
to 121 format
. For ex; col1
and col2
formats (below) are same (other than the 0s at the end)
SELECT CONVERT(varchar, GETDATE(), 121) col1,
CAST(convert(datetime2,GETDATE()) as varchar) col2,
CAST(GETDATE() as varchar) col3
--Results
COL1 | COL2 | COL3
2013-02-08 09:53:56.223 | 2013-02-08 09:53:56.2230000 | Feb 8 2013 9:53AM
FYI, if you use CONVERT
instead of CAST
you can use a third parameter to specify certain formats as listed here on MSDN
A simple (but maybe flawed) way that works in Python 2 and 3:
import time
import datetime
def utc_to_local(dt):
return dt - datetime.timedelta(seconds = time.timezone)
Its advantage is that it's trivial to write an inverse function
If there is no sub-directory, you can also take
ls | xargs -I {} dos2unix "{}"

As you want to specifically search for a wildcard character you need to escape that
This is done by adding the ESCAPE
clause to your LIKE
expression. The character that is specified with the ESCAPE
clause will "invalidate" the following wildcard character.
You can use any character you like (just not a wildcard character). Most people use a \
because that is what many programming languages also use
So your query would result in:
select *
from Manager
where managerid LIKE '\_%' escape '\'
and managername like '%\_%' escape '\';
But you can just as well use any other character:
select *
from Manager
where managerid LIKE '#_%' escape '#'
and managername like '%#_%' escape '#';

It looks like you forgot the prefix on the color attribute. Try

You've got a couple regexes now which will do what you want, so that's adequately covered.
What hasn't been mentioned is why your attempt won't work: Inside a character class, $
(as well as ^
, .
, and /
) has no special meaning, so [/$]
matches either a literal /
or a literal $
rather than terminating the regex (/
) or matching end-of-line ($
).
The vroom package provides a 'tidy' method of selecting / dropping columns by name during import. Docs: https://www.tidyverse.org/blog/2019/05/vroom-1-0-0/#column-selection
The vroom argument 'col_select' makes selecting columns to keep (or omit) more straightforward. The interface for col_select is the same as dplyr::select().
Select columns by namedata <- vroom("flights.tsv", col_select = c(year, flight, tailnum))

# * * * * * user-name command to be executed
I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.
To run something every minute:
* * * * * username /var/www/html/a.php
To run something at midnight of every day:
0 0 * * * username /var/www/html/reset.php
You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:
chmod +x file.php
Start your php file with a shebang so that your shell knows which interpreter to use:
#!/usr/bin/php
<?php
// your code here
I'd suggest marking the Hibernate DAO class with @Primary
, i.e. (assuming you used @Repository
on HibernateDeviceDao
):
@Primary
@Repository
public class HibernateDeviceDao implements DeviceDao
This way it will be selected as the default autowire candididate, with no need to autowire-candidate
on the other bean.
Also, rather than using @Autowired @Qualifier
, I find it more elegant to use @Resource
for picking specific beans, i.e.
@Resource(name="jdbcDeviceDao")
DeviceDao deviceDao;
If you have <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
but want this: <?xml version="1.0" encoding="UTF-8"?>
Just do:
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
marshaller.setProperty("com.sun.xml.internal.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
I can recommend the SVG Primer (published by the W3C), which covers this topic: http://www.w3.org/Graphics/SVG/IG/resources/svgprimer.html#SVG_in_HTML
If you use <object>
then you get raster fallback for free*:
<object data="your.svg" type="image/svg+xml">
<img src="yourfallback.jpg" />
</object>
*) Well, not quite for free, because some browsers download both resources, see Larry's suggestion below for how to get around that.
2014 update:
If you want a non-interactive svg, use <img>
with script fallbacks
to png version (for older IE and android < 3). One clean and simple
way to do that:
<img src="your.svg" onerror="this.src='your.png'">
.
This will behave much like a GIF image, and if your browser supports declarative animations (SMIL) then those will play.
If you want an interactive svg, use either <iframe>
or <object>
.
If you need to provide older browsers the ability to use an svg plugin, then use <embed>
.
For svg in css background-image
and similar properties, modernizr is one choice for switching to fallback images, another is depending on multiple backgrounds to do it automatically:
div {
background-image: url(fallback.png);
background-image: url(your.svg), none;
}
Note: the multiple backgrounds strategy doesn't work on Android 2.3 because it supports multiple backgrounds but not svg.
An additional good read is this blogpost on svg fallbacks.
We can also use SQL kind of expression inside filter :
Note -> Here I am showing two conditions and a date range for future reference :
ordersDf.filter("order_status = 'PENDING_PAYMENT' AND order_date BETWEEN '2013-07-01' AND '2013-07-31' ")
This is another method . Passing array as a pointer to the function
void generateArray(int *array, int size) {
srand(time(0));
for (int j=0;j<size;j++)
array[j]=(0+rand()%9);
}
int main(){
const int size=5;
int a[size];
generateArray(a, size);
return 0;
}
Here is simple overlay div without using any gif, This can be applied over another div.
<style>
.loader {
position: relative;
border: 16px solid #f3f3f3;
border-radius: 50%;
border-top: 16px solid #3498db;
width: 70px;
height: 70px;
left:50%;
top:50%;
-webkit-animation: spin 2s linear infinite; /* Safari */
animation: spin 2s linear infinite;
}
#overlay{
position: absolute;
top:0px;
left:0px;
width: 100%;
height: 100%;
background: black;
opacity: .5;
}
.container{
position:relative;
height: 300px;
width: 200px;
border:1px solid
}
/* Safari */
@-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
</style>
<h2>How To Create A Loader</h2>
<div class="container">
<h3>Overlay over this div</h3>
<div id="overlay">
<div class="loader"></div>
</div>
<div>
Make left-margin: 2em or so will push the whole text including first line to right 2em. Than add text-indent (applicable to first line) as -2em or so.. This brings first line back to start without margin. I tried it for list tags
<style>
ul li{
margin-left: 2em;
text-indent: -2em;
}
</style>
To append to an array, just use the +=
operator.
$Target += $TargetObject
Also, you need to declare $Target = @()
before your loop because otherwise, it will empty the array every loop.
You didn't state what web server you were using, but Apache has a nice little module called Mime Magic which it uses to determine the type of a file when told to do so. It reads some of the file's content and tries to figure out what type it is based on the characters found. And as Dave Webb Mentioned the MimeTypes Module under python will work, provided an extension is handy.
Alternatively, if you are sitting on a UNIX box you can use sys.popen('file -i ' + fileName, mode='r')
to grab the MIME type. Windows should have an equivalent command, but I'm unsure as to what it is.
First I am afraid your question contains a little mistake. There is not method writeline in class Console. Instead class Console provides method writer() that returns PrintWriter. This print writer has println().
Now what is the difference between
System.console().writer().println("hello from console");
and
System.out.println("hello system out");
If you run your application from command line I think there is no difference. But if console is unavailable System.console() returns null while System.out still exists. This may happen if you invoke your application and perform redirect of STDOUT to file.
Here is an example I have just implemented.
import java.io.Console;
public class TestConsole {
public static void main(String[] args) {
Console console = System.console();
System.out.println("console=" + console);
console.writer().println("hello from console");
}
}
When I ran the application from command prompt I got the following:
$ java TestConsole
console=java.io.Console@93dcd
hello from console
but when I redirected the STDOUT to file...
$ java TestConsole >/tmp/test
Exception in thread "main" java.lang.NullPointerException
at TestConsole.main(TestConsole.java:8)
Line 8 is console.writer().println()
.
Here is the content of /tmp/test
console=null
I hope my explanations help.
npm install @types/jasmine
As mentioned in some comments the "types": ["jasmine"]
is not needed anymore, all @types
packages are automatically included in compilation (since v2.1 I think).
In my opinion the easiest solution is to exclude the test files in your tsconfig.json like:
"exclude": [
"node_modules",
"**/*.spec.ts"
]
This works for me.
Further information in the official tsconfig docs.
Another option is using the overloaded + operator
:
>>> l = ['hello','world']
>>> l = ['foo'] + l
>>> l
['foo', 'hello', 'world']
You can get another validation on this tutorial : http://twitterbootstrap.org/bootstrap-form-validation
They use JQuery validation.
jquery.validate.js
jquery.validate.min.js
jquery-1.7.1.min.js
And you'll get the source code there.

happy coding.
Use .closest()
with a selector:
var $div = $('#divid').closest('div[class^="div-a"]');
This code worked for me
public static void main(String[] args) {
try {
java.net.URL myUr = new java.net.URL("http://path");
System.out.println("Instantiated new URL: " + connection_url);
}
catch (MalformedURLException e) {
e.printStackTrace();
}
}
Instantiated new URL: http://path
Update your SP and handle exception in it using declare handler with get diagnostics so that you will know if there is an exception. e.g.
CREATE DEFINER=`root`@`localhost` PROCEDURE `validar_egreso`(
IN codigo_producto VARCHAR(100),
IN cantidad INT,
OUT valido INT(11)
)
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
GET DIAGNOSTICS CONDITION 1
@p1 = RETURNED_SQLSTATE, @p2 = MESSAGE_TEXT;
SELECT @p1, @p2;
END
DECLARE resta INT(11);
SET resta = 0;
SELECT (s.stock - cantidad) INTO resta
FROM stock AS s
WHERE codigo_producto = s.codigo;
IF (resta > s.stock_minimo) THEN
SET valido = 1;
ELSE
SET valido = -1;
END IF;
SELECT valido;
END
We can separate out section of which we need to convert in PDF
For example, if table is in class "pdf-table-wrap"
After this, we need to call html2canvas function combined with jsPDF
following is sample code
var pdf = new jsPDF('p', 'pt', [580, 630]);
html2canvas($(".pdf-table-wrap")[0], {
onrendered: function(canvas) {
document.body.appendChild(canvas);
var ctx = canvas.getContext('2d');
var imgData = canvas.toDataURL("image/png", 1.0);
var width = canvas.width;
var height = canvas.clientHeight;
pdf.addImage(imgData, 'PNG', 20, 20, (width - 10), (height));
}
});
setTimeout(function() {
//jsPDF code to save file
pdf.save('sample.pdf');
}, 0);
Complete tutorial is given here http://freakyjolly.com/create-multipage-html-pdf-jspdf-html2canvas/
If you want the month year unique pair, using apply is pretty sleek.
df['mnth_yr'] = df['date_column'].apply(lambda x: x.strftime('%B-%Y'))
Outputs month-year in one column.
Don't forget to first change the format to date-time before, I generally forget.
df['date_column'] = pd.to_datetime(df['date_column'])
if(!$('#select-box').find("option:contains('" + thevalue + "')").length){_x000D_
//do stuff_x000D_
}
_x000D_
Try with this combination of Lambda expressions:
employees.ToList().ForEach(emp =>
{
collection.AddRange(emp.Departments);
emp.Departments.ToList().ForEach(dept => dept.SomeProperty = null);
});
Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:
s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum
Select the below code and drag that into in BOOKMARK BAR (if you don't see it, enable from Browser Settings), then EDIT that link :
javascript:var my_params = prompt("Enter your parameters", "var1=aaaa&var2=bbbbb"); var Target_LINK = prompt("Enter destination", location.href); function post(path, params) { var xForm = document.createElement("form"); xForm.setAttribute("method", "post"); xForm.setAttribute("action", path); for (var key in params) { if (params.hasOwnProperty(key)) { var hiddenField = document.createElement("input"); hiddenField.setAttribute("name", key); hiddenField.setAttribute("value", params[key]); xForm.appendChild(hiddenField); } } var xhr = new XMLHttpRequest(); xhr.onload = function () { alert(xhr.responseText); }; xhr.open(xForm.method, xForm.action, true); xhr.send(new FormData(xForm)); return false; } parsed_params = {}; my_params.split("&").forEach(function (item) { var s = item.split("="), k = s[0], v = s[1]; parsed_params[k] = v; }); post(Target_LINK, parsed_params); void(0);
That's all! Now you can visit any website, and click that button in BOOKMARK BAR!
The above method sends data using XMLHttpRequest
method, so, you have to be on the same domain while triggering the script. That's why I prefer sending data with a simulated FORM SUBMITTING, which can send the code to any domain - here is code for that:
javascript:var my_params=prompt("Enter your parameters","var1=aaaa&var2=bbbbb"); var Target_LINK=prompt("Enter destination", location.href); function post(path, params) { var xForm= document.createElement("form"); xForm.setAttribute("method", "post"); xForm.setAttribute("action", path); xForm.setAttribute("target", "_blank"); for(var key in params) { if(params.hasOwnProperty(key)) { var hiddenField = document.createElement("input"); hiddenField.setAttribute("name", key); hiddenField.setAttribute("value", params[key]); xForm.appendChild(hiddenField); } } document.body.appendChild(xForm); xForm.submit(); } parsed_params={}; my_params.split("&").forEach(function(item) {var s = item.split("="), k=s[0], v=s[1]; parsed_params[k] = v;}); post(Target_LINK, parsed_params); void(0);
if you are using Jupyter Notebook, How about....
%%timeit
df.isnull().any().any()
or
%timeit
df.isnull().values.sum()
or, are there anywhere NaNs in the data, if yes, where?
df.isnull().any()
This command works for me. It does its work recursively
find . -name "node_modules" -type d -prune -exec rm -rf '{}' +
. - current folder
"node_modules" - folder name
first of all;
a Fragment
must be inside a FragmentActivity
, that's the first rule,
a FragmentActivity
is quite similar to a standart Activity
that you already know, besides having some Fragment oriented methods
second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView
, where you inflate your layout, think of it as the setContentLayout
here is an example:
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { mView = inflater.inflate(R.layout.fragment_layout, container, false); return mView; }
and continu your work based on that mView, so to find a View
by id, call mView.findViewById(..);
for the FragmentActivity
part:
the xml part "must" have a FrameLayout
in order to inflate a fragment in it
<FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout>
as for the inflation part
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();
begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site
# Every 30 minutes, not on the hour<br>
# Grabs maxlifetime directly from \`php -i\`<br>
# doesn't care if /var/lib/php5 exists, errs go to /dev/null<br>
09,39 * * * * find /var/lib/php5/ -type f -cmin +$(echo "\`php -i|grep -i session.gc_maxlifetime|cut -d' ' -f3\` / 60" | bc) -exec rm -f {} \\; >/dev/null 2>&1
The Breakdown:
Only files: find /var/lib/php5/ -type f
Older than minutes: -cmin
Get php settings: $(echo "`php -i|grep -i session.gc_maxlifetime
Do the math: |cut -d' ' -f3` / 60" | bc)
RM matching files: -exec rm -f {} \;
You simply use the destroy()
method to delete the specified widgets like this:
lbl = tk.Label(....)
btn = tk.Button(....., command=lambda: lbl.destroy())
Using this you can completely destroy the specific widgets.
I had the same issue and deleting the store and reading didn't work. I had to do the following.
Get a copy of OpenSSL. It is available for Windows. Or use a Linux box as they all pretty much all have it.
Run the following to export to a key file:
openssl pkcs12 -in certfile.pfx -out backupcertfile.key
openssl pkcs12 -export -out certfiletosignwith.pfx -keysig -in backupcertfile.key
Then in the project properties you can use the PFX file.
I don't believe this is a good pattern to use in general. Link will run your onClick event and then navigate to the route, so there will be a slight delay navigating to the new route. A better strategy is to navigate to the new route with the 'to' prop as you have done, and in the new component's componentDidMount() function you can fire your hello function or any other function. It will give you the same result, but with a much smoother transition between routes.
For context, I noticed this while updating my redux store with an onClick event on Link like you have here, and it caused a ~.3 second blank-white-screen delay before mounting the new route's component. There was no api call involved, so I was surprised the delay was so big. However, if you're just console logging 'hello' the delay might not be noticeable.
When creating constants in a jar file, it is often helpful to let users extend enum values. We used enums for PropertyFile keys and got stuck because nobody could add any new ones! Below would have worked much better.
Given:
public interface Color {
String fetchName();
}
and:
public class MarkTest {
public static void main(String[] args) {
MarkTest.showColor(Colors.BLUE);
MarkTest.showColor(MyColors.BROWN);
}
private static void showColor(Color c) {
System.out.println(c.fetchName());
}
}
one could have one enum in the jar:
public enum Colors implements Color {
BLUE, RED, GREEN;
@Override
public String fetchName() {
return this.name();
}
}
and a user could extend it to add his own colors:
public enum MyColors implements Color {
BROWN, GREEN, YELLOW;
@Override
public String fetchName() {
return this.name();
}
}
Use security.ignored
property:
security.ignored=/**
security.basic.enable: false
will just disable some part of the security auto-configurations but your WebSecurityConfig
still will be registered.
There is a default security password generated at startup
Try to Autowired
the AuthenticationManagerBuilder
:
@Override
@Autowired
protected void configure(AuthenticationManagerBuilder auth) throws Exception { ... }
Its simple:
Make your element hidden first like this:
<div id="hidden" style="display:none;">
Hi this is hidden
</div>
Then call your javascript:
<script type="text/javascript">
$(document).ready(function() {
$.fancybox("#hidden");
});
</script>
Check out the image below:
Another example:
<div id="example2" style="display:none;">
<img src="http://theinstitute.ieee.org/img/07tiProductsandServicesiStockphoto-1311258460873.jpg" />
</div>
<script type="text/javascript">
$(document).ready(function() {
$.fancybox("#example2");
});
</script>
pip install pywin32
didn't work for me but pypiwin32
did.
I believe you can just assign the empty set ({}
) to your variable.
struct x instance;
for(i = 0; i < n; i++) {
instance = {};
/* Do Calculations */
}
As odd as it sound when you want to permit nested attributes you do specify the attributes of nested object within an array. In your case it would be
Update as suggested by @RafaelOliveira
params.require(:measurement)
.permit(:name, :groundtruth => [:type, :coordinates => []])
On the other hand if you want nested of multiple objects then you wrap it inside a hash… like this
params.require(:foo).permit(:bar, {:baz => [:x, :y]})
Rails actually have pretty good documentation on this: http://api.rubyonrails.org/classes/ActionController/Parameters.html#method-i-permit
For further clarification, you could look at the implementation of permit
and strong_parameters
itself: https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/metal/strong_parameters.rb#L246-L247
The other answers were not completely satisfying to me. Here's what worked for postgresql-9.1 on Xubuntu 12.04.1 LTS.
Connect to the default database with user postgres:
sudo -u postgres psql template1
Set the password for user postgres, then exit psql (Ctrl-D):
ALTER USER postgres with encrypted password 'xxxxxxx';
Edit the pg_hba.conf
file:
sudo vim /etc/postgresql/9.1/main/pg_hba.conf
and change "peer" to "md5" on the line concerning postgres:
local all postgres
peermd5
To know what version of postgresql you are running, look for the version folder under /etc/postgresql
. Also, you can use Nano or other editor instead of VIM.
Restart the database :
sudo /etc/init.d/postgresql restart
(Here you can check if it worked with psql -U postgres
).
Create a user having the same name as you (to find it, you can type whoami
):
sudo createuser -U postgres -d -e -E -l -P -r -s
<my_name>
The options tell postgresql to create a user that can login, create databases, create new roles, is a superuser, and will have an encrypted password. The really important ones are -P -E, so that you're asked to type the password that will be encrypted, and -d so that you can do a createdb
.
Beware of passwords: it will first ask you twice the new password (for the new user), repeated, and then once the postgres password (the one specified on step 2).
Again, edit the pg_hba.conf
file (see step 3 above), and change "peer" to "md5" on the line concerning "all" other users:
local all all
peermd5
Restart (like in step 4), and check that you can login without -U postgres:
psql template1
Note that if you do a mere psql
, it will fail since it will try to connect you to a default database having the same name as you (i.e. whoami
). template1 is the admin database that is here from the start.
Now createdb <dbname>
should work.
The server's address is stored in config.php
Not necessarily better, but since it's nice to have options here's how to do it using Jinja statements:
- debug:
msg: "{% for address in network.addresses.private_man %}\
{% if address.type == 'fixed' %}\
{{ address.addr }}\
{% endif %}\
{% endfor %}"
Or if you prefer to put it all on one line:
- debug:
msg: "{% for address in network.addresses.private_man if address.type == 'fixed' %}{{ address.addr }}{% endfor %}"
Which returns:
ok: [localhost] => {
"msg": "172.16.1.100"
}
If you plan to create a PHP package you most likely want to put in on Packagist to make it available for other with composer.
Composer has the as naming-convention to use vendorname/package-name-is-lowercase-with-hyphens
.
If you plan to create a JS package you probably want to use npm. One of their naming conventions is to not permit upper case letters in the middle of your package name.
Therefore, I would recommend for PHP and JS packages to use lowercase-with-hyphens
and name your packages in composer or npm identically to your package on GitHub.
Don't forget to close your form with a </form>
. That stopped submit() working for me.
If there's a padding error it probably means your string is corrupted; base64-encoded strings should have a multiple of four length. You can try adding the padding character (=
) yourself to make the string a multiple of four, but it should already have that unless something is wrong
This will do:
#include <fstream>
#include <iostream>
using std::fstream;
int main(int argc, char *argv[]) {
fstream file;
file.open("test.txt",std::ios::out);
file << fflush;
file.close();
}
An answer to your Question from 2019:
It depends on what version of ECMAScript you use.
Pre ES6:
Use any of the answers below, e.g.:
for (var m in myMap){
for (var i=0;i<myMap[m].length;i++){
... do something with myMap[m][i] ...
}
}
For ES6 (ES 2015):
You should use a Map
object, which has the entries()
function:
var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");
for (const [key, value] of myMap.entries()) {
console.log(key, value);
}
For ES8 (ES 2017):
Object.entries()
was introduced:
const object = {'a': 1, 'b': 2, 'c' : 3};
for (const [key, value] of Object.entries(object)) {
console.log(key, value);
}
Edit 2017:
use ggplot and theme(legend.position = ""):
library(ggplot2)
library(reshape2)
set.seed(121)
a=sample(1:100,5)
b=sample(1:100,5)
c=sample(1:100,5)
df = data.frame(number = 1:5,a,b,c)
df_long <- melt(df,id.vars = "number")
ggplot(data=df_long,aes(x = number,y=value, colour=variable)) +geom_line() +
theme(legend.position="bottom")
Original answer 2012: Put the legend on the bottom:
set.seed(121)
a=sample(1:100,5)
b=sample(1:100,5)
c=sample(1:100,5)
dev.off()
layout(rbind(1,2), heights=c(7,1)) # put legend on bottom 1/8th of the chart
plot(a,type='l',ylim=c(min(c(a,b,c)),max(c(a,b,c))))
lines(b,lty=2)
lines(c,lty=3,col='blue')
# setup for no margins on the legend
par(mar=c(0, 0, 0, 0))

Use a comma to specify two (or more) different rules:
@media screen and (max-width: 995px),
screen and (max-height: 700px) {
...
}
From https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries
Commas are used to combine multiple media queries into a single rule. Each query in a comma-separated list is treated separately from the others. Thus, if any of the queries in a list is true, the entire media statement returns true. In other words, lists behave like a logical or operator.
I actually like the previous answer (don't use the SP), but if you're tied to the SP itself for some reason, you could use it to populate a temp table, and then join on the temp table. Note that you're going to cost yourself some additional overhead there, but it's the only way I can think of to use the actual stored proc.
Again, you may be better off in-lining the query from the SP into the original query.
I know this is a little old but I wanted to add an updated answer with f-strings which were introduced in Python version 3.6:
msg['Subject'] = f'Auto Hella Restart Report {sys.argv[1]}'
In your example a credit card is expired on 6/2008.
Without knowing what you are doing I cannot say definitively you should not be validating ahead of time but be aware that sometimes business rules defy all logic.
For example, where I used to work they often did not process a card at all or would continue on transaction failure simply so they could contact the customer and get a different card.
You do not need to use substring at all since your format
doesn't hold that info.
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";
Date fechaNueva = format.parse(fechaStr);
System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29
Clustering aims at finding groups in data. “Cluster” is an intuitive concept and does not have a mathematically rigorous definition. The members of one cluster should be similar to one another and dissimilar to the members of other clusters. A clustering algorithm operates on an unlabeled data set Z and produces a partition on it.
For Classes and Class Labels, class contains similar objects, whereas objects from different classes are dissimilar. Some classes have a clear-cut meaning, and in the simplest case are mutually exclusive. For example, in signature verification, the signature is either genuine or forged. The true class is one of the two, no matter that we might not be able to guess correctly from the observation of a particular signature.
I have tried something like this and it works as expected:
f = open("c:\\log.log", 'r+b')
f.write("\x5F\x9D\x3E")
f.read(100)
f.close()
Where:
f.read(size) - To read a file’s contents, call f.read(size), which reads some quantity of data and returns it as a string.
And:
f.write(string) writes the contents of string to the file, returning None.
Also if you open Python tutorial about reading and writing files you will find that:
'r+' opens the file for both reading and writing.
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'.
I got this error and i fixed the issue with iconv
function like following:
iconv('latin5', 'utf-8', $data['index']);
this is my solution, it works with the most common domains, you can fit the array of extensions as you need:
$SubDomain = explode('.', explode('|ext|', str_replace(array('.com', '.net', '.org'), '|ext|',$_SERVER['HTTP_HOST']))[0]);
There is probably another table with a foreign key referencing the primary key you are trying to change.
To find out which table caused the error you can run SHOW ENGINE INNODB STATUS
and then look at the LATEST FOREIGN KEY ERROR
section.
To represent a unicode string as a string of bytes is known as encoding. Use u'...'.encode(encoding)
.
Example:
>>> u'æøå'.encode('utf8') '\xc3\x83\xc2\xa6\xc3\x83\xc2\xb8\xc3\x83\xc2\xa5' >>> u'æøå'.encode('latin1') '\xc3\xa6\xc3\xb8\xc3\xa5' >>> u'æøå'.encode('ascii') UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-5: ordinal not in range(128)
You typically encode a unicode string whenever you need to use it for IO, for instance transfer it over the network, or save it to a disk file.
To convert a string of bytes to a unicode string is known as decoding. Use unicode('...', encoding)
or '...'.decode(encoding).
Example:
>>> u'æøå' u'\xc3\xa6\xc3\xb8\xc3\xa5' # the interpreter prints the unicode object like so >>> unicode('\xc3\xa6\xc3\xb8\xc3\xa5', 'latin1') u'\xc3\xa6\xc3\xb8\xc3\xa5' >>> '\xc3\xa6\xc3\xb8\xc3\xa5'.decode('latin1') u'\xc3\xa6\xc3\xb8\xc3\xa5'
You typically decode a string of bytes whenever you receive string data from the network or from a disk file.
I believe there are some changes in unicode handling in python 3, so the above is probably not correct for python 3.

I updated to Yosemite and Android Studio wouldn't clean my projects or Run them on virtual or real device because of the following error:
Failed to complete Gradle execution.Cause:Supplied javaHome is not a valid folder. You supplied: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
After some research and trouble shooting, I found that the JDK file that was being pointed to at "/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home" wasn't there; all of "JavaVirtualMachines/1.6.0.jdk/Contents/Home" was missing from "/System/Library/Java". So, I copied "JavaVirtualMachines/1.6.0.jdk/Contents/Home" over from "/Library/Java/" to "/System/Library/Java/" and cha ching! I was back in business.

I solved it in two steps. To rename folder using mv command you need rights to do so, if you don't have right you can follow these steps. Suppose you want to rename casesensitive to Casesensitive.
Step 1: Rename the folder (casesensitive) to something else from explorer. eg Rename casesensitive to folder1 commit this change.
Step 2: Rename this newly named folder(folder1) to the expected case sensitive name (Casesensitive ) eg. Rename folder1 to Casesensitive. Commit this change.
The worst one I saw was the non-use :-)
Someone wrote a strcpy (I think that was it... over 10 years ago now) function inside of a method (because they didn't want the overhead of calling strcpy... sigh).
They clued in that it wouldn't work for Japanese characters so they added an "if" at the start to do ASCII or Unicode. At that point the code was about a screen long... likely killing cache coherency and erasing his supposed savings for the inlining of the code.
The code was identical save for the types (so should have used a macro).
Of course the strcpy that they wrote was much much much slower than the hand tuned assembler one that was in the standard library...
Of course if they had just done it all as a macro it could have been replaced with a call to strcpy...
Of course I quit the company (not directly because of that...)
DT[order(-x)]
works as expected. I have data.table version 1.9.4. Maybe this was fixed in a recent version.
Also, I suggest the setorder(DT, -x)
syntax in keeping with the set* commands like setnames
, setkey
Nothing above worked, this is what worked for me:
ftype Python.File=C:\Path\to\python.exe "%1" %*
This command should be run in Command prompt launched as administrator
Warning: even if the path in this command is set to python35, if you have python36 installed it's going to set the default to python36. To prevent this, you can temporarily change the folder name from Python36
to xxPython36
, run the command and then remove the change to the Python 36 folder.
Mmh ... there are many ways. I answer another network discovery question, and I write a little getting started.
Some tcpip stacks reply to icmp broadcasts. So you can try a PING to your network broadcast address.
For example, you have ip 192.168.1.1 and subnet 255.255.255.0
Note : on step 3. you get the lists of the MAC-to-IP cached entries, so there are also the hosts in your subnet you exchange data to in the last minutes, even if they don't reply to icmp_get.
Note (2) : now I am on linux. I am not sure, but it can be windows doesn't reply to icm_get via broadcast.
Is it the only one device attached to your pc ? Is it a router or another simple pc ?
