Here's a way to do it in Python without NumPy. Create a function that returns what you want and use a list comprehension, or the map function.
>>> a = [1, 2, 3, -4, 5]
>>> def zero_if_negative(x):
... if x < 0:
... return 0
... return x
...
>>> [zero_if_negative(x) for x in a]
[1, 2, 3, 0, 5]
>>> map(zero_if_negative, a)
[1, 2, 3, 0, 5]
We need to remember that the {% endif %}
comes after the {% else %}
.
So this is an example:
{% if someTest %}
<p> Something is True </p>
{% else %}
<p> Something is False </p>
{% endif %}
I know this doesn't use flexbox, but for the simple use-case of three items (one at left, one at center, one at right), this can be accomplished easily using display: grid
on the parent, grid-area: 1/1/1/1;
on the children, and justify-self
for positioning of those children.
<div style="border: 1px solid red; display: grid; width: 100px; height: 25px;">_x000D_
<div style="border: 1px solid blue; width: 25px; grid-area: 1/1/1/1; justify-self: left;"></div>_x000D_
<div style="border: 1px solid blue; width: 25px; grid-area: 1/1/1/1; justify-self: center;"></div>_x000D_
<div style="border: 1px solid blue; width: 25px; grid-area: 1/1/1/1; justify-self: right;"></div>_x000D_
</div>

I have used the following logic in SSRS reports.
BUS_DATE = 17-09-2013
X=DATEADD(MONTH,-1,BUS_DATE) = 17-08-2013
Y=DAY(BUS_DATE)=17
first_date = DATEADD(DAY,-Y+1,X)=01-08-2013
last_date = DATEADD(DAY,-Y,BUS_DATE)=31-08-2013
It appears that as of Java 7, David Santamaria's answer doesn't work reliably any more. It looks like you can still reliably use a Socket to test the connection, however.
private static boolean available(int port) {
System.out.println("--------------Testing port " + port);
Socket s = null;
try {
s = new Socket("localhost", port);
// If the code makes it this far without an exception it means
// something is using the port and has responded.
System.out.println("--------------Port " + port + " is not available");
return false;
} catch (IOException e) {
System.out.println("--------------Port " + port + " is available");
return true;
} finally {
if( s != null){
try {
s.close();
} catch (IOException e) {
throw new RuntimeException("You should handle this error." , e);
}
}
}
}
I got it
Cells(1, 1).Value = StartDate
Cells(1, 1).NumberFormat = "dd/mm/yyyy"
Basically, I need to set the cell format, instead of setting the date.
Self plug: I have just released a new Java HTML parser: jsoup. I mention it here because I think it will do what you are after.
Its party trick is a CSS selector syntax to find elements, e.g.:
String html = "<html><head><title>First parse</title></head>"
+ "<body><p>Parsed HTML into a doc.</p></body></html>";
Document doc = Jsoup.parse(html);
Elements links = doc.select("a");
Element head = doc.select("head").first();
See the Selector javadoc for more info.
This is a new project, so any ideas for improvement are very welcome!
I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.
I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.
<input type="password" placeholder="Enter New Password" autocomplete="new-password">

Don't know why, my Neon Eclipse still having this issue, it doesn't seem to be fixed in Mars version as many people said.
I found that using command is too troublesome, I delete the plugin away via the Eclipse Installation Manager.
Just select the plugin "Dali Java Persistence Tools -JPA Support" and click "uninstall" will do. Please take note my screen below doesn't have that because I already uninstalled.
It depends upon what you mean by split. If you want to iterate over words in a line, which is in a variable, you can just iterate. For example, let's say the variable line
is this is a line
. Then you can do this:
for word in $line; do echo $word; done
This will print:
this
is
a
line
for .. in $var
splits $var
using the values in $IFS
, the default value of which means "split blanks and newlines".
If you want to read lines from user or a file, you can do something like:
cat $filename | while read line
do
echo "Processing new line" >/dev/tty
for word in $line
do
echo $word
done
done
For anything else, you need to be more explicit and define your question in more detail.
Note: Edited to remove bashism, but I still kept cat $filename | ...
because I like it more than redirection.
Give the textbox an id of "txtValue" and change the input button declaration to the following:
<input type="button" value="submit" onclick="verifyorder(document.getElementById('txtValue').value)" />
Check out XmlTextReader class for instance.
You can even use this one. worked well for me
$("#registerform").attr("action", "register.php?btnsubmit=Save")
$('#registerform').submit();
this will submit btnsubmit =Save as GET value to register.php form.
Try this, I have got success response ..it's working
$("#divId").css("background-image", "url('data:image/png;base64," + base64String + "')");
you can use pathlib
from pathlib import Path
Path(r"C:\folder1\folder2\filename.xml").parts[-2]
The output of the above was this:

Try to declare UseHttpGet over your method.
[ScriptMethod(UseHttpGet = true)]

Easy way for older C++, or C:
#include <time.h> // includes clock_t and CLOCKS_PER_SEC
int main() {
clock_t start, end;
start = clock();
// ...code to measure...
end = clock();
double duration_sec = double(end-start)/CLOCKS_PER_SEC;
return 0;
}
Timing precision in seconds is 1.0/CLOCKS_PER_SEC
This works for me in Ansible 2.9:
variable1 = www.example.com.
variable2 = www.example.org.
when: ".com" in variable1
and for not:
when: not ".com" in variable2
I solved that adding a Web facet.
If the main intent is to check whether the supplied value is not found in a list, maybe you can use the extended regular expression matching built in BASH via the "equal tilde" operator (see also this answer):

The SQL-Server implementation of this will be:

From Files and Filegroups Architecture
Secondary data files
Secondary data files make up all the data files, other than the primary data file. Some databases may not have any secondary data files, while others have several secondary data files. The recommended file name extension for secondary data files is .ndf.
Also from file extension NDF - Microsoft SQL Server secondary data file
See Understanding Files and Filegroups
Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.
The recommended file name extension for secondary data files is .ndf.
/
For example, three files, Data1.ndf, Data2.ndf, and Data3.ndf, can be created on three disk drives, respectively, and assigned to the filegroup fgroup1. A table can then be created specifically on the filegroup fgroup1. Queries for data from the table will be spread across the three disks; this will improve performance. The same performance improvement can be accomplished by using a single file created on a RAID (redundant array of independent disks) stripe set. However, files and filegroups let you easily add new files to new disks.

Found a one-liner that works in Chrome 66 from: http://www.yournewdesigner.com/css-experiments/javascript-window-close-firefox.html
TLDR: tricks the browser into believing JavaScirpt opened the current tab/window
window.open('', '_parent', '').close();
So for completeness
<input type="button" name="close" value="close" onclick="window.close();">
Though let it also be noted that readers may want to place this into a function that fingerprints which browsers require such trickery, because Firefox 59 doesn't work with the above.
I know that there is already a solution to this question, but I found an alternative to this issue and maybe it could help someone.
I was having trouble with setting the frame of my sub view because certain values were referring to its position within the main view. So if you don't want to update your frame by changing the whole frame via CGRect, you can simply change a value of the frame and then update it.
// keep reference to you frames
var questionView = questionFrame.frame
var answerView = answerFrame.frame
// update the values of the copy
questionView.size.height = CGFloat(screenSize.height * 0.70)
answerView.size.height = CGFloat(screenSize.height * 0.30)
// set the frames to the new frames
questionFrame.frame = questionView
answerFrame.frame = answerView
Put your if condition inside resize
function:
var windowsize = $(window).width();
$(window).resize(function() {
windowsize = $(window).width();

//if the window is greater than 440px wide then turn on jScrollPane..
$('#pane1').jScrollPane({
scrollbarWidth:15,
scrollbarMargin:52
});
}

Pure html is not able to do what you want. My suggestion would be to write a simple javascript function to do the roudning for you.
This is not possible.
In Python, there really isn't any such thing as a "variable". What Python really has are "names" which can have objects bound to them. It makes no difference to the object what names, if any, it might be bound to. It might be bound to dozens of different names, or none.
Consider this example:
foo = 1
bar = 1
baz = 1
Now, suppose you have the integer object with value 1, and you want to work backwards and find its name. What would you print? Three different names have that object bound to them, and all are equally valid.
In Python, a name is a way to access an object, so there is no way to work with names directly. There might be some clever way to hack the Python bytecodes or something to get the value of the name, but that is at best a parlor trick.
If you know you want print foo
to print "foo"
, you might as well just execute print "foo"
in the first place.
EDIT: I have changed the wording slightly to make this more clear. Also, here is an even better example:
foo = 1
bar = foo
baz = foo
In practice, Python reuses the same object for integers with common values like 0 or 1, so the first example should bind the same object to all three names. But this example is crystal clear: the same object is bound to foo, bar, and baz.
Little addition in answer if you have different user rather then dbo
then do like this.
EXEC [ServerName].[DatabaseName].dbo.sp_HelpText '[user].[storedProcName]'
There is no solution that works for all use cases. If you use the $request->get('_route') method, or its variants, it will return '_internal' for cases where forwarding took place.
If you need a solution that works even with forwarding, you have to use the new RequestStack service, that arrived in 2.4, but this will break ESI support:
$requestStack = $container->get('request_stack');
$masterRequest = $requestStack->getMasterRequest(); // this is the call that breaks ESI
if ($masterRequest) {
echo $masterRequest->attributes->get('_route');
}
You can make a twig extension out of this if you need it in templates.
Continued discussion & other solutions covered at How to sort an (associative) array by value? with the best solution (for my case) being by saml (quoted below).
Arrays can only have numeric indexes. You'd need to rewrite this as either an Object, or an Array of Objects.
var status = new Array();
status.push({name: 'BOB', val: 10});
status.push({name: 'TOM', val: 3});
status.push({name: 'ROB', val: 22});
status.push({name: 'JON', val: 7});
If you like the status.push
method, you can sort it with:
status.sort(function(a,b) {
return a.val - b.val;
});
I presume you've got validate_required() function from this page: http://www.w3schools.com/js/js_form_validation.asp?
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
}
In this case your last condition will not work as you expect it.
You can replace it with this:
if (password.value != cpassword.value) {
alert("Your password and confirmation password do not match.");
cpassword.focus();
return false;
}
Set your local domain to mywebsite.example.com
(and redirect it to localhost) -- even though the usual is to use mywebsite.dev
. This will allow robust automatic testing.
Although authorizing .test
and .dev
is not allowed, authorizing example.com
is allowed in google oauth2.
(You can redirect any domain to localhost in your hosts file (unix/linux: /etc/hosts
))
Why mywebsite.example.com
?
Because example.com
is a reserved domain name. So
not-redirected-by-mistake.example.com
.To use a simple example, I had a counter that needed to summarise unique IP addresses per visited page on a site. Which is basically grouping by pagename and then by IP. I solved it with a combination of DISTINCT and GROUP BY.
SELECT pagename, COUNT(DISTINCT ipaddress) AS visit_count FROM log_visitors GROUP BY pagename ORDER BY visit_count DESC;

Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 255 before MySQL 5.0.3, and 0 to 65,535 in 5.0.3 and later versions. The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.
- So ...
< MySQL 5.0.3 use TEXT
or
>= MySQL 5.0.3 use VARCHAR(2083)
The problem is that they're all the same exact list in memory. When you use the [x]*n
syntax, what you get is a list of n
many x
objects, but they're all references to the same object. They're not distinct instances, rather, just n
references to the same instance.
To make a list of 3 different lists, do this:
x = [[] for i in range(3)]
This gives you 3 separate instances of []
, which is what you want
[[]]*n
is similar to
l = []
x = []
for i in range(n):
x.append(l)
While [[] for i in range(3)]
is similar to:
x = []
for i in range(n):
x.append([]) # appending a new list!
In [20]: x = [[]] * 4
In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object
In [22]: x=[[] for i in range(4)]
In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

I've seen this style being used:
if (when || who || format || data || len);
Step-1: Your Model class
public class RechargeMobileViewModel
{
public string CustomerFullName { get; set; }
public string TelecomSubscriber { get; set; }
public int TotalAmount { get; set; }
public string MobileNumber { get; set; }
public int Month { get; set; }
public List<SelectListItem> getAllDaysList { get; set; }
// Define the list which you have to show in Drop down List
public List<SelectListItem> getAllWeekDaysList()
{
List<SelectListItem> myList = new List<SelectListItem>();
var data = new[]{
new SelectListItem{ Value="1",Text="Monday"},
new SelectListItem{ Value="2",Text="Tuesday"},
new SelectListItem{ Value="3",Text="Wednesday"},
new SelectListItem{ Value="4",Text="Thrusday"},
new SelectListItem{ Value="5",Text="Friday"},
new SelectListItem{ Value="6",Text="Saturday"},
new SelectListItem{ Value="7",Text="Sunday"},
};
myList = data.ToList();
return myList;
}
}
Step-2: Call this method to fill Drop down in your controller Action
namespace MvcVariousApplication.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
RechargeMobileViewModel objModel = new RechargeMobileViewModel();
objModel.getAllDaysList = objModel.getAllWeekDaysList();
return View(objModel);
}
}
}
Step-3: Fill your Drop-Down List of View as follows
@model MvcVariousApplication.Models.RechargeMobileViewModel
@{
ViewBag.Title = "Contact";
}
@Html.LabelFor(model=> model.CustomerFullName)
@Html.TextBoxFor(model => model.CustomerFullName)
@Html.LabelFor(model => model.MobileNumber)
@Html.TextBoxFor(model => model.MobileNumber)
@Html.LabelFor(model => model.TelecomSubscriber)
@Html.TextBoxFor(model => model.TelecomSubscriber)
@Html.LabelFor(model => model.TotalAmount)
@Html.TextBoxFor(model => model.TotalAmount)
@Html.LabelFor(model => model.Month)
@Html.DropDownListFor(model => model.Month, new SelectList(Model.getAllDaysList, "Value", "Text"), "-Select Day-")
You can delete everything and recreate database + seeds with both:
rake db:reset
: loads from schema.rbrake db:drop db:create db:migrate db:seed
: loads from migrationsMake sure you have no connections to db (rails server, sql client..) or the db won't drop.
schema.rb is a snapshot of the current state of your database generated by:
rake db:schema:dump
Just use:
ViewController *viewController = [[ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
navController.navigationBarHidden = YES;
[self presentViewController:navController animated:YES completion: nil];
[viewController release];
[navController release];
instead you could easily do it this way :
<html>
<body>
<script type="text/javascript">
<?php
$myVar = "hello";
?>
document.write("<?php echo $myVar ?>");
</script>
</body>
try this one

urlc.setConnectTimeout(3000);
urlc.setReadTimeout(4000);
urlc.connect();
// networkcode2 = urlc.getResponseCode();
return (urlc.getResponseCode() == 200);
} catch (IOException e) {

NetworkInfo networkInfo = cm.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {

return false;
}
}
you'll have to add the following permission to your manifest file:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
Then call like that:
if((new ConnectionDetector(MyService.this)).isConnectingToInternet()){
Log.d("internet status","Internet Access");
}else{
Log.d("internet status","no Internet Access");
}
Generally speaking, you should not put anything into META-INF yourself. Instead, you should rely upon whatever you use to package up your JAR. This is one of the areas where I think Ant really excels: specifying JAR file manifest attributes. It's very easy to say something like:
<jar ...>
<manifest>
<attribute name="Main-Class" value="MyApplication"/>
</manifest>
</jar>
At least, I think that's easy... :-)
The point is that META-INF should be considered an internal Java meta directory. Don't mess with it! Any files you want to include with your JAR should be placed in some other sub-directory or at the root of the JAR itself.
Your best bet is to have a look at strptime()
Something along the lines of
>>> from datetime import datetime
>>> date_str = 'Tue May 08 15:14:45 +0800 2012'
>>> date = datetime.strptime(date_str, '%a %B %d %H:%M:%S +0800 %Y')
>>> date
datetime.datetime(2012, 5, 8, 15, 14, 45)
Im not sure how to do the +0800 timezone unfortunately, maybe someone else can help out with that.
The formatting strings can be found at http://docs.python.org/library/time.html#time.strftime and are the same for formatting the string for printing.
Hope that helps
Mark
PS, Your best bet for timezones in installing pytz from pypi. ( http://pytz.sourceforge.net/ ) in fact I think pytz has a great datetime parsing method if i remember correctly. The standard lib is a little thin on the ground with timezone functionality.
Well, you could erase()
the first character too (note that erase()
modifies the string):
m_VirtualHostName.erase(0, 1);
m_VirtualHostName.erase(m_VirtualHostName.size() - 1);
But in this case, a simpler way is to take a substring:
m_VirtualHostName = m_VirtualHostName.substr(1, m_VirtualHostName.size() - 2);
Be careful to validate that the string actually has at least two characters in it first...
Hm.. My solution is working:
Mymodel.objects.filter(date_time_field__startswith=datetime.datetime(1986, 7, 28))
No, you can simply use com.fasterxml.jackson.databind.ObjectMapper
.
Most likely you forgot to fix your import
-statements, delete all references to codehaus and you're golden.

Supplementing the answer by p.s.w.g
, here are three other ways of achieving this using lodash
4.17.5
, without using _.includes()
:
Say you want to add object entry
to an array of objects numbers
, only if entry
does not exist already.
let numbers = [
{ to: 1, from: 2 },
{ to: 3, from: 4 },
{ to: 5, from: 6 },
{ to: 7, from: 8 },
{ to: 1, from: 2 } // intentionally added duplicate
];
let entry = { to: 1, from: 2 };
/*
* 1. This will return the *index of the first* element that matches:
*/
_.findIndex(numbers, (o) => { return _.isMatch(o, entry) });
// output: 0
/*
* 2. This will return the entry that matches. Even if the entry exists
* multiple time, it is only returned once.
*/
_.find(numbers, (o) => { return _.isMatch(o, entry) });
// output: {to: 1, from: 2}
/*
* 3. This will return an array of objects containing all the matches.
* If an entry exists multiple times, if is returned multiple times.
*/
_.filter(numbers, _.matches(entry));
// output: [{to: 1, from: 2}, {to: 1, from: 2}]
If you want to return a Boolean
, in the first case, you can check the index that is being returned:
_.findIndex(numbers, (o) => { return _.isMatch(o, entry) }) > -1;
// output: true

In batch, the >
is a redirection sign used to output data into a text file. The compare op's available (And recommended) for cmd are below (quoted from the if /?
help):
where compare-op may be one of:
EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal
That should explain what you want. The only other compare-op is ==
which can be switched with the if not
parameter. Other then that rely on these three letter ones.
You can use
public static final String HELLO = "hello";
if you have many string constants, you can use external property file / simple "constant holder" class

This other comment about using a new network comes pretty close to the solution for me, and was working for a while, but I found a better way thanks to some talk over in another question
Create a network with:
docker network create your-network --subnet 172.24.24.0/24
Then, at the bottom of docker-compose.yaml, put this:
networks:
default:
external:
name: your-network
Done. No need to add networks to all container definitions etc. and you can re-use the network with other docker-compose files as well if you'd like.
You would get an error for using sns.figure.savefig("output.png")
in seaborn 0.8.1.
Instead use:
import seaborn as sns
df = sns.load_dataset('iris')
sns_plot = sns.pairplot(df, hue='species', size=2.5)
sns_plot.savefig("output.png")

There is a fast way to initialize array of any type with given value. It works very well with large arrays. Algorithm is as follows:
For 1 000 000
elements int
array it is 4 times faster than regular loop initialization (i5, 2 cores, 2.3 GHz, 4GiB memory, 64 bits):
loop runtime 0.004248 [seconds]
memfill() runtime 0.001085 [seconds]
#include <stdio.h>
#include <time.h>
#include <string.h>
#define ARR_SIZE 1000000
void memfill(void *dest, size_t destsize, size_t elemsize) {
char *nextdest = (char *) dest + elemsize;
size_t movesize, donesize = elemsize;
destsize -= elemsize;
while (destsize) {
movesize = (donesize < destsize) ? donesize : destsize;
memcpy(nextdest, dest, movesize);
nextdest += movesize; destsize -= movesize; donesize += movesize;
}
}
int main() {
clock_t timeStart;
double runTime;
int i, a[ARR_SIZE];
timeStart = clock();
for (i = 0; i < ARR_SIZE; i++)
a[i] = 9;
runTime = (double)(clock() - timeStart) / (double)CLOCKS_PER_SEC;
printf("loop runtime %f [seconds]\n",runTime);
timeStart = clock();
a[0] = 10;
memfill(a, sizeof(a), sizeof(a[0]));
runTime = (double)(clock() - timeStart) / (double)CLOCKS_PER_SEC;
printf("memfill() runtime %f [seconds]\n",runTime);
return 0;
}
So do the following ,
Lets say your branch name is my_branch and this has the extra commits.
git checkout -b my_branch_with_extra_commits
(Keeping this branch saved under a different name)gitk
(Opens git console)git checkout my_branch
gitk
(This will open the git console )reset branch to here
" git pull --rebase origin branch_name_to _merge_to
git cherry-pick <SHA you copied in step 3. >
Now look at the local branch commit history and make sure everything looks good.
gene_name = no_headers.iloc[1:,[1]]
This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:
gene_name[x]
you now have a Series object with a single value. You can't hash the Series.
The solution is to create Series from the start.
gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]
Also, where you have orph_dict[gene_name[x]] =+ 1
, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1
to increment the counter.
I had the same question for macOS.
But the root cause was not installing Six. My macOS shipped Python version 2.7 was being usurped by a Python2 version I inherited by installing a package via brew

If you are allowed to run real native binaries, then this is your compiler:
https://github.com/ircmaxell/php-compiler
It's a PHP compiler written in PHP!
It compiles PHP code to its own VM code. This VM code can then either be interpreted by its own interpreter (also written in PHP, isn't that crazy?) or it can be translated to Bitcode. And using the LLVM compiler framework (clang
and co), this Bitcode can be compiled into a native binary for any platform that LLVM supports (pretty much any platform that matters today). You can choose to either do that statically or each time just before the code is executed (JIT style). So the only two requirements for this compiler to work on your system is an installed PHP interpreter and an installed clang
compiler.
If you are not allowed to run native binaries, you could use the compiler above as an interpreter and let it interpret its own VM code, yet this will be slow as you are running a PHP interpreter that itself is running on a PHP engine, so you have a "double interpretation".
I haven't actually had a chance to try this myself yet, but next time I'm setting up a project with a big requirement for INotifyPropertyChanged I'm intending on writing a Postsharp attribute that will inject the code at compile time. Something like:
[NotifiesChange]
public string FirstName { get; set; }
Will become:
private string _firstName;
public string FirstName
{
get { return _firstname; }
set
{
if (_firstname != value)
{
_firstname = value;
OnPropertyChanged("FirstName")
}
}
}
I'm not sure if this will work in practice and I need to sit down and try it out, but I don't see why not. I may need to make it accept some parameters for situations where more than one OnPropertyChanged needs to be triggered (if, for example, I had a FullName property in the class above)
Currently I'm using a custom template in Resharper, but even with that I'm getting fed up of all my properties being so long.
Ah, a quick Google search (which I should have done before I wrote this) shows that at least one person has done something like this before here. Not exactly what I had in mind, but close enough to show that the theory is good.
It has to do with the Normal Form for the SQL language. IF
statements can, by definition, only take a single SQL statement. However, there is a special kind of SQL statement which can contain multiple SQL statements, the BEGIN-END
block.
If you omit the BEGIN-END
block, your SQL will run fine, but it will only execute the first statement as part of the IF
.
Basically, this:
IF @Term = 3
INSERT INTO @Classes
SELECT
XXXXXX
FROM XXXX blah blah blah
is equivalent to the same thing with the BEGIN-END
block, because you are only executing a single statement. However, for the same reason that not including the curly-braces on an IF
statement in a C-like language is a bad idea, it is always preferable to use BEGIN
and END
.
Here's a practical example (build a dataset from your current location):
$ds = new-object System.Data.DataSet
$ds.Tables.Add("tblTest")
[void]$ds.Tables["tblTest"].Columns.Add("Name",[string])
[void]$ds.Tables["tblTest"].Columns.Add("Path",[string])
dir | foreach {
$dr = $ds.Tables["tblTest"].NewRow()
$dr["Name"] = $_.name
$dr["Path"] = $_.fullname
$ds.Tables["tblTest"].Rows.Add($dr)
}
$ds.Tables["tblTest"]
$ds.Tables["tblTest"]
is an object that you can manipulate just like any other Powershell object:
$ds.Tables["tblTest"] | foreach {
write-host 'Name value is : $_.name
write-host 'Path value is : $_.path
}
In my Visual Studio 2019 it worked only after I set the AutoSizeColumnsMode
property to None
.
if you are use using notepad: then
public String toString(){
return ""; ---now here you can use variables which you have created for your class
}
if you are using eclipse IDE then press
-alt +shift +s
-click on override toString method here you will get options to select what type of variables you want to select.
The code can be written simpler as following.
view.subviews.forEach { $0.removeFromSuperview() }
angularBlogServices.factory('BlogPost', ['$resource',
function($resource) {
return $resource("./Post/:id", {}, {
get: {method: 'GET', cache: true, isArray: false},
save: {method: 'POST', cache: false, isArray: false},
update: {method: 'PUT', cache: false, isArray: false},
delete: {method: 'DELETE', cache: false, isArray: false}
});
}]);
set cache to be true.
If you just want to delete the address assigned to the user and not to affect on User entity class you should try something like that:
@Entity
public class User {
@OneToMany(mappedBy = "addressOwner", cascade = CascadeType.ALL)
protected Set<Address> userAddresses = new HashSet<>();
}
@Entity
public class Addresses {
@ManyToOne(cascade = CascadeType.REFRESH) @JoinColumn(name = "user_id")
protected User addressOwner;
}
This way you dont need to worry about using fetch in annotations. But remember when deleting the User you will also delete connected address to user object.
$hash_type$salt$password
If the hash does not use a salt, then there is no $
sign for that. The actual hash in your case is after the 2nd $
The reason for this is, so you can have many types of hashes with different salts and feeds that string into a function that knows how to match it with some other value.
With WinForms you can use the ErrorProvider in conjunction with the Validating
event to handle the validation of user input. The Validating
event provides the hook to perform the validation and ErrorProvider gives a nice consistent approach to providing the user with feedback on any error conditions.

SELECT CONVERT_TZ() will work for that.but its not working for me.
Why, what error do you get?
SELECT CONVERT_TZ(displaytime,'GMT','MET');
should work if your column type is timestamp, or date
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_convert-tz
Test how this works:
SELECT CONVERT_TZ(a_ad_display.displaytime,'+00:00','+04:00');
Check your timezone-table
SELECT * FROM mysql.time_zone;
SELECT * FROM mysql.time_zone_name;
http://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html
If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql
program to load the Time Zone Tables. Please try this
shell> mysql_tzinfo_to_sql /usr/share/zoneinfo
or if not working read more: http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html
The relevant specification for PUT and POST is RFC 2616 §9.5ff.
POST creates a child resource, so POST to /items
creates a resources that lives under the /items
resource.
Eg. /items/1
. Sending the same post packet twice will create two resources.
PUT is for creating or replacing a resource at a URL known by the client.
Therefore: PUT is only a candidate for CREATE where the client already knows the url before the resource is created. Eg. /blogs/nigel/entry/when_to_use_post_vs_put
as the title is used as the resource key
PUT replaces the resource at the known url if it already exists, so sending the same request twice has no effect. In other words, calls to PUT are idempotent.
The RFC reads like this:
The fundamental difference between the POST and PUT requests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resource that will handle the enclosed entity. That resource might be a data-accepting process, a gateway to some other protocol, or a separate entity that accepts annotations. In contrast, the URI in a PUT request identifies the entity enclosed with the request -- the user agent knows what URI is intended and the server MUST NOT attempt to apply the request to some other resource. If the server desires that the request be applied to a different URI,
Note: PUT has mostly been used to update resources (by replacing them in their entireties), but recently there is movement towards using PATCH for updating existing resources, as PUT specifies that it replaces the whole resource. RFC 5789.
Update 2018: There is a case that can be made to avoid PUT. See "REST without PUT"
With “REST without PUT” technique, the idea is that consumers are forced to post new 'nounified' request resources. As discussed earlier, changing a customer’s mailing address is a POST to a new “ChangeOfAddress” resource, not a PUT of a “Customer” resource with a different mailing address field value.
taken from REST API Design - Resource Modeling by Prakash Subramaniam of Thoughtworks
This forces the API to avoid state transition problems with multiple clients updating a single resource, and matches more nicely with event sourcing and CQRS. When the work is done asynchronously, POSTing the transformation and waiting for it to be applied seems appropriate.
Here is another lib and seems to be the best in my opinion. I did not write it..
UPDATE:
This code seems to work best for me and it moves the entire Actionbar similar to the G+ app.

When a method only takes a reference type as a parameter (say a generic method constrained to be a class via the new
constraint), you will not be able to pass a reference type to it and have to box it.
This is also true for any methods that take object
as a parameter - this will have to be a reference type.
This is the preferred method for iOS 7 and higher
In your application's Info.plist
, set View controller-based status bar appearance
to YES
.
Override preferredStatusBarStyle
(Apple docs) in each of your view controllers. For example:
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
If you have preferredStatusBarStyle
returning a different preferred status bar style based on something that changes inside of your view controller (for example, whether the scroll position or whether a displayed image is dark), then you will want to call setNeedsStatusBarAppearanceUpdate()
when that state changes.
iOS before version 7, deprecated method
Apple has deprecated this, so it will be removed in the future. Use the above method so that you don't have to rewrite it when the next iOS version is released.
If your application will support In your application's Info.plist
, set View controller-based status bar appearance
to NO
.
In appDelegate.swift
, the didFinishLaunchingWithOptions
function, add:
UIApplication.shared.statusBarStyle = .lightContent
For Navigation Controller
If you use a navigation controller and you want the preferred status bar style of each view controller to be used and set View controller-based status bar appearance
to YES
in your application's info.plist
extension UINavigationController {
open override var preferredStatusBarStyle: UIStatusBarStyle {
return topViewController?.preferredStatusBarStyle ?? .default
}
}
You want .children()
instead (documentation here):
$(this).closest('tr').children('td.two').text();
I would always encode in UTF-8. From the Wikipedia page on percent encoding:
The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values. This requirement was introduced in January 2005 with the publication of RFC 3986. URI schemes introduced before this date are not affected.
It seems like because there were other accepted ways of doing URL encoding in the past, browsers attempt several methods of decoding a URI, but if you're the one doing the encoding you should use UTF-8.
For Laravel 5.x, use $storage_path = storage_path()
.
From the Laravel 5.0 docs:
storage_path
Get the fully qualified path to the
storage
directory.
Note also that, for Laravel 5.1 and above, per the Laravel 5.1 docs:
You may also use the
storage_path
function to generate a fully qualified path to a given file relative to the storage directory:$path = storage_path('app/file.txt');
I've solved this problem using JDK 7 with this code:
package FileCreationDate;
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.Date;
import java.util.concurrent.TimeUnit;
public class Main
{
public static void main(String[] args) {
File file = new File("c:\\1.txt");
Path filePath = file.toPath();
BasicFileAttributes attributes = null;
try
{
attributes =
Files.readAttributes(filePath, BasicFileAttributes.class);
}
catch (IOException exception)
{
System.out.println("Exception handled when trying to get file " +
"attributes: " + exception.getMessage());
}
long milliseconds = attributes.creationTime().to(TimeUnit.MILLISECONDS);
if((milliseconds > Long.MIN_VALUE) && (milliseconds < Long.MAX_VALUE))
{
Date creationDate =
new Date(attributes.creationTime().to(TimeUnit.MILLISECONDS));
System.out.println("File " + filePath.toString() + " created " +
creationDate.getDate() + "/" +
(creationDate.getMonth() + 1) + "/" +
(creationDate.getYear() + 1900));
}
}
}
The following will create a variable length set of arguments of the type of string:
print(String arg1, String... arg2)
You can then refer to arg2
as an array of Strings. This is a new feature in Java 5.
Suppose your HTML form has id="form_id"

I found the answer today. Maybe its too late but still I think its a much better one. Check this one https://jsfiddle.net/Amar_newDev/khb2oyru/5/
Try to change the CSS code : <ul> max-width:1%; margin:auto; text-align:left; </ul>
max-width:80% or something like that.
Try experimenting you might find something new.
This might not be the best method, but you can ignore the conversion error if all else fails. Mine was an issue of nulls not converting properly, so I just ignored the error and the dates came in as dates and the nulls came in as nulls, so no data quality issues--not that this would always be the case. To do this, right click on your source, click Edit, then Error Output. Go to the column that's giving you grief and under Error change it to Ignore Failure.
Doing $('body').find();
is not necessary when looking up by ID; there is no performance gain.
Please also note that having an ID that starts with a number is not valid HTML:
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").
right-click the view in the object-explorer, select "script view as...", then "create to" and then "new query editor window"
The other answers assume that the array contains strings. My method is better, because it will work even if the array contains null, undefined, or other non-strings.
var notdefined;
var myarray = ['a', 'c', null, notdefined, 'nulk', 'BYE', 'nulm'];
myarray.sort(ignoreCase);
alert(JSON.stringify(myarray)); // show the result
function ignoreCase(a,b) {
return (''+a).toUpperCase() < (''+b).toUpperCase() ? -1 : 1;
}
The null
will be sorted between 'nulk' and 'nulm'. But the undefined
will be always sorted last.
I was using find
to provide a list of files for xgettext
, and wanted to omit a specific directory and its contents. I tried many permutations of -path
combined with -prune
but was unable to fully exclude the directory which I wanted gone.
Although I was able to ignore the contents of the directory which I wanted ignored, find
then returned the directory itself as one of the results, which caused xgettext
to crash as a result (doesn't accept directories; only files).
My solution was to simply use grep -v
to skip the directory that I didn't want in the results:
find /project/directory -iname '*.php' -or -iname '*.phtml' | grep -iv '/some/directory' | xargs xgettext
Whether or not there is an argument for find
that will work 100%, I cannot say for certain. Using grep
was a quick and easy solution after some headache.
The only way I know is this:
Reassure that preferences | Basic Notes Client configuration | Drag and drop saves as eml file is checked
1) Drag your email to e.g. your desktop or to an explorer instance (will be saved as an eml file).
2) Attach this file to your opened email by either selecting it with the paperclip menu item or drag 'n drop the file into the opened email.
Here's my solution:
public static int div_by_3(long a) {
a <<= 30;
for(int i = 2; i <= 32 ; i <<= 1) {
a = add(a, a >> i);
}
return (int) (a >> 32);
}
public static long add(long a, long b) {
long carry = (a & b) << 1;
long sum = (a ^ b);
return carry == 0 ? sum : add(carry, sum);
}
First, note that
1/3 = 1/4 + 1/16 + 1/64 + ...
Now, the rest is simple!
a/3 = a * 1/3
a/3 = a * (1/4 + 1/16 + 1/64 + ...)
a/3 = a/4 + a/16 + 1/64 + ...
a/3 = a >> 2 + a >> 4 + a >> 6 + ...
Now all we have to do is add together these bit shifted values of a! Oops! We can't add though, so instead, we'll have to write an add function using bit-wise operators! If you're familiar with bit-wise operators, my solution should look fairly simple... but just in-case you aren't, I'll walk through an example at the end.
Another thing to note is that first I shift left by 30! This is to make sure that the fractions don't get rounded off.
11 + 6
1011 + 0110
sum = 1011 ^ 0110 = 1101
carry = (1011 & 0110) << 1 = 0010 << 1 = 0100
Now you recurse!
1101 + 0100
sum = 1101 ^ 0100 = 1001
carry = (1101 & 0100) << 1 = 0100 << 1 = 1000
Again!
1001 + 1000
sum = 1001 ^ 1000 = 0001
carry = (1001 & 1000) << 1 = 1000 << 1 = 10000
One last time!
0001 + 10000
sum = 0001 ^ 10000 = 10001 = 17
carry = (0001 & 10000) << 1 = 0
Done!
It's simply carry addition that you learned as a child!

This implementation failed because we can not add all terms of the equation:

f(a, i) = a/4 + a/4^2 + ... + a/4^i
Suppose the reslut of div_by_3(a)

The first (excellent) answer stated -
The method with count() is unsafe. If another session deletes the row that met the condition after the line with the count(*), and before the line with the select ... into, the code will throw an exception that will not get handled.
Not so. Within a given logical Unit of Work Oracle is totally consistent. Even if someone commits the delete of the row between a count and a select Oracle will, for the active session, obtain the data from the logs. If it cannot, you will get a "snapshot too old" error.
I prefer the following one-liner approach using str.rsplit():
my_filename.rsplit('.', 1)[0] + '.jpg'
Example:
>>> my_filename = '/home/user/somefile.txt'
>>> my_filename.rsplit('.', 1)
>>> ['/home/user/somefile', 'txt']
The trim() method removes whitespace from both sides of a string.
You can use a Javascript replace method to remove white space like
"hello world".replace(/\s/g, "");
var out = "hello world".replace(/\s/g, "");_x000D_
console.log(out);

I recommend you to use the open-source package guzzle that is fully unit tested and uses the latest coding practices.
Installing Guzzle
Go to the command line in your project folder and type in the following command (assuming you already have the package manager composer installed). If you need help how to install Composer, you should have a look here.
php composer.phar require guzzlehttp/guzzle
Using Guzzle to send a POST request
The usage of Guzzle is very straight forward as it uses a light-weight object-oriented API:
// Initialize Guzzle client
$client = new GuzzleHttp\Client();
// Create a POST request
$response = $client->request(

Short answer: in POST requests, values are sent in the "body" of the request. With web-forms they are most likely sent with a media type of application/x-www-form-urlencoded
or multipart/form-data
. Programming languages or frameworks which have been designed to handle web-requests usually do "The Right Thing™" with such requests and provide you with easy access to the readily decoded values (like $_REQUEST
or $_POST
in PHP, or cgi.FieldStorage()
, flask.request.form
in Python).
Now let's digress a bit, which may help understand the difference ;)
The difference between GET
and POST
requests are largely semantic. They are also "used" differently, which explains the difference in how values are passed.
When executing a GET
request, you ask the server for one, or a set of entities. To allow the client to filter the result, it can use the so called "query string" of the URL. The query string is the part after the ?
. This is part of the URI syntax.
So, from the point of view of your application code (the part which receives the request), you will need to inspect the URI query part to gain access to these values.
Note that the keys and values are part of the URI. Browsers may impose a limit on URI length. The HTTP standard states that there is no limit. But at the time of this writing, most browsers do limit the URIs (I don't have specific values). GET
requests should never be used to submit new information to the server. Especially not larger documents. That's where you should use POST
or PUT
.
When executing a POST
request, the client is actually submitting a new document to the remote host. So, a query string does not (semantically) make sense. Which is why you don't have access to them in your application code.
POST
is a little bit more complex (and way more flexible):
When receiving a POST request, you should always expect a "payload", or, in HTTP terms: a message body. The message body in itself is pretty useless, as there is no standard (as far as I can tell. Maybe application/octet-stream?) format. The body format is defined by the Content-Type
header. When using a HTML FORM
element with method="POST"
, this is usually application/x-www-form-urlencoded
. Another very common type is multipart/form-data if you use file uploads. But it could be anything, ranging from text/plain
, over application/json
or even a custom application/octet-stream
.
In any case, if a POST
request is made with a Content-Type
which cannot be handled by the application, it should return a 415
status-code.
Most programming languages (and/or web-frameworks) offer a way to de/encode the message body from/to the most common types (like application/x-www-form-urlencoded
, multipart/form-data
or application/json
). So that's easy. Custom types require potentially a bit more work.
Using a standard HTML form encoded document as example, the application should perform the following steps:
Content-Type
field415
status codeAgain, languages like PHP, or web-frameworks for other popular languages will probably handle this for you. The exception to this is the 415
error. No framework can predict which content-types your application chooses to support and/or not support. This is up to you.
A PUT
request is pretty much handled in the exact same way as a POST
request. The big difference is that a POST
request is supposed to let the server decide how to (and if at all) create a new resource. Historically (from the now obsolete RFC2616 it was to create a new resource as a "subordinate" (child) of the URI where the request was sent to).
A PUT
request in contrast is supposed to "deposit" a resource exactly at that URI, and with exactly that content. No more, no less. The idea is that the client is responsible to craft the complete resource before "PUTting" it. The server should accept it as-is on the given URL.
As a consequence, a POST
request is usually not used to replace an existing resource. A PUT
request can do both create and replace.
There are also "path parameters" which can be used to send additional data to the remote, but they are so uncommon, that I won't go into too much detail here. But, for reference, here is an excerpt from the RFC:
Aside from dot-segments in hierarchical paths, a path segment is considered opaque by the generic syntax. URI producing applications often use the reserved characters allowed in a segment to delimit scheme-specific or dereference-handler-specific subcomponents. For example, the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes. For example, one URI producer might use a segment such as "name;v=1.1" to indicate a reference to version 1.1 of "name", whereas another might use a segment such as "name,1.1" to indicate the same. Parameter types may be defined by scheme-specific semantics, but in most cases the syntax of a parameter is specific to the implementation of the URIs dereferencing algorithm.
This task can be accomplished using one of the android's main building block named as Intents and One of the methods public void startActivity (Intent intent)
which belongs to your Activity class.
An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.
An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
Refer the official docs -- http://developer.android.com/reference/android/content/Intent.html
public void startActivity (Intent intent)
-- Used to launch a new activity.
So suppose you have two Activity class --
PresentActivity -- This is your current activity from which you want to go the second activity.
NextActivity -- This is your next Activity on which you want to move.
So the Intent would be like this
Intent(PresentActivity.this, NextActivity.class)
Finally this will be the complete code
public class PresentActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.content_layout_id);
final Button button = (Button) findViewById(R.id.button_id);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Intent activityChangeIntent = new Intent(PresentActivity.this, NextActivity.class);
// currentContext.startActivity(activityChangeIntent);
PresentActivity.this.startActivity(activityChangeIntent);
}
});
}
}

.join(model.ClassificationItem)
.join(model.EnumerationValue)
.filter_by(id=c.row.id)

)
)
sqlalchemy.sql.expression.desc(column) Produce a descending ORDER BY clause element.
e.g.:
from sqlalchemy import desc stmt = select([users_table]).order_by(desc(users_table.c.name))
will produce SQL as:
SELECT id, name FROM user ORDER BY name DESC
The desc() function is a standalone version of the ColumnElement.desc() method available on all SQL expressions, e.g.:
stmt = select([users_table]).order_by(users_table.c.name.desc())
Parameters column – A ColumnElement (e.g. scalar SQL expression) with which to apply the desc() operation.

angular.element(domElement).injector()
to get the current app injector
angular.element(domElement).controller()
to get a hold of the ng-controller instance.

The number in parentheses specifies the precision of fractional seconds to be stored. So, (0)
would mean don't store any fraction of a second, and use only whole seconds. The default value if unspecified is 6 digits after the decimal separator.
So an unspecified value would store a date like:
TIMESTAMP 24-JAN-2012 08.00.05.993847 AM
And specifying (0)
stores only:
TIMESTAMP(0) 24-JAN-2012 08.00.05 AM
Dominc has the right idea, but put the calculation on the other side of the expression.
SELECT * FROM my_table WHERE endTime < DATE_SUB(CONVERT_TZ(NOW(), @@global.time_zone, 'GMT'), INTERVAL 30 MINUTE)
This has the advantage that you're doing the 30 minute calculation once instead of on every row. That also means MySQL can use the index on that column. Both of thse give you a speedup.

I've made it to be simple as possible. but it still in its early days. Let me know the feedback so I could improve it.
This assumes a few things, that you know what the output file name will be and that your data comes as a string. I'm sure you can modify the following to meet your needs:
// Needed Imports
import java.io.ByteArrayInputStream;
import sun.misc.BASE64Decoder;
def sourceData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAPAAAADwCAYAAAA+VemSAAAgAEl...==';
// tokenize the data
def parts = sourceData.tokenize(",");
def imageString = parts[1];
// create a buffered image
BufferedImage image = null;
byte[] imageByte;
BASE64Decoder decoder = new BASE64Decoder();
imageByte = decoder.decodeBuffer(imageString);
ByteArrayInputStream bis = new ByteArrayInputStream(imageByte);
image = ImageIO.read(bis);
bis.close();
// write the image to a file
File outputfile = new File("image.png");
ImageIO.write(image, "png", outputfile);
Please note, this is just an example of what parts are involved. I haven't optimized this code at all and it's written off the top of my head.
I think you can just do
std::string s( MyVector.begin(), MyVector.end() );
where MyVector is your std::vector.

Editing file /etc/apt/sources.list.d/additional-repositories.list

worked for me, this post was very helpful https://github.com/typora/typora-issues/issues/2065
Nothing in the example says that the "classes implementing the same interface". MovieCatalog
is a type and CustomerPreferenceDao
is another type. Spring can easily tell them apart.
In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".
What the examples show is various ways that you can use to inject beans into fields, methods and constructors.
The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:
This autowiring will fail:
@Autowired
public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }
Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier
:
@Autowired
public void prepare( @Qualifier("bean1") Interface1 bean1,
@Qualifier("bean2") Interface1 bean2 ) { ... }
From all I have read you cannot do exactly what you want without javascript. If you float left before text
<div style="float:left;">widget</div> here is some CONTENT, etc.
Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content
here is some CONTENT, etc. <div style="float:left;">widget</div>
Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:
here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>
In your question you are using bootstrap which just adds row-fluid::after { content: ""}
which resolves the border/background issue.
Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/
<div class="container-fluid">
<div class="row-fluid">
<div class="offset1 span8 pull-right">
... Widget 1...
</div>
.... a lot of content ....
<div class="span8" style="margin-left: 0;">
... Widget 2...
</div>
</div>
</div><!--/.fluid-container-->
For the checked out branch, in the case the commit you want to point to is ahead of the current branch (which should be the case unless you want to undo the last commits of the current branch), you can simply do:
git merge --ff-only <commit>
This makes a softer alternative to git reset --hard
, and will fail if you are not in the case described above.
To do the same thing for a non checked out branch, the equivalent would be:
git push . <commit>:<branch>
Someone mentioned using slower chips to prevent ions from flipping bits as easily. In a similar fashion perhaps use a specialized cpu/ram that actually uses multiple bits to store a single bit. Thus providing a hardware fault tolerance because it would be very unlikely that all of the bits would get flipped. So 1 = 1111 but would need to get hit 4 times to actually flipped. (4 might be a bad number since if 2 bits get flipped its already ambiguous). So if you go with 8, you get 8 times less ram and some fraction slower access time but a much more reliable data representation. You could probably do this both on the software level with a specialized compiler(allocate x amount more space for everything) or language implementation (write wrappers for data structures that allocate things this way). Or specialized hardware that has the same logical structure but does this in the firmware.
I wanted to add something to the answer already provided. maven-compiler-plugin by default will compile your project using Java 1.5 which is where m2e get's its information.
That's why you have to explicitly declare the maven-compiler-plugin in your project with something other then 1.5. Your effective pom.xml
will implicitly use the default set in the maven-compiler-plugin pom.xml
.
This is the already proposed and accepted solution as a method on the Array prototype:
Array.prototype.sortNumeric = function () {
return this.sort((a, b) => a - b);
};
Array.prototype.sortNumericDesc = function () {
return this.sort((a, b) => b - a);
};
Replace all latters from any language in 'A', and if you wish for example all digits to 0:
return str.replace(/[^\s!-@[-`{-~]/g, "A").replace(/\d/g, "0");
Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.
1. Can not instantiate abstract class: Classes defined as abstract may not be instantiated, and any class that contains at least one abstract method must also be abstract.
Example below :
abstract class AbstractClass
{
abstract protected function getValue();
abstract protected function prefixValue($prefix);
public function printOut() {
echo "Hello how are you?";
}
}
$obj=new AbstractClass();
$obj->printOut();
//Fatal error: Cannot instantiate abstract class AbstractClass
2. Any class that contains at least one abstract method must also be abstract: Abstract class can have abstract and non-abstract methods, but it must contain at least one abstract method. If a class has at least one abstract method, then the class must be declared abstract.
Note: Traits support the use of abstract methods in order to impose requirements upon the exhibiting class.
Example below :
class Non_Abstract_Class
{
abstract protected function getValue();
public function printOut() {
echo "Hello how are you?";
}
}
$obj=new Non_Abstract_Class();
$obj->printOut();
//Fatal error: Class Non_Abstract_Class contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Non_Abstract_Class::getValue)
3. An abstract method can not contain body: Methods defined as abstract simply declare the method's signature - they cannot define the implementation. But a non-abstract method can define the implementation.
abstract class AbstractClass
{
abstract protected function getValue(){
return "Hello how are you?";
}
public function printOut() {
echo $this->getValue() . "\n";
}
}
class ConcreteClass1 extends AbstractClass
{
protected function getValue() {
return "ConcreteClass1";
}
public function prefixValue($prefix) {
return "{$prefix}ConcreteClass1";
}
}
$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue('FOO_') ."\n";
//Fatal error: Abstract function AbstractClass::getValue() cannot contain body
4. When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child :If you inherit an abstract class you have to provide implementations to all the abstract methods in it.
abstract class AbstractClass
{
// Force Extending class to define this method
abstract protected function getValue();
// Common method
public function printOut() {
print $this->getValue() . "<br/>";
}
}
class ConcreteClass1 extends AbstractClass
{
public function printOut() {
echo "dhairya";
}
}
$class1 = new ConcreteClass1;
$class1->printOut();
//Fatal error: Class ConcreteClass1 contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (AbstractClass::getValue)
5. Same (or a less restricted) visibility:When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child; additionally, these methods must be defined with the same (or a less restricted) visibility. For example, if the abstract method is defined as protected, the function implementation must be defined as either protected or public, but not private.
Note that abstract method should not be private.
abstract class AbstractClass
{
abstract public function getValue();
abstract protected function prefixValue($prefix);
public function printOut() {
print $this->getValue();
}
}
class ConcreteClass1 extends AbstractClass
{
protected function getValue() {
return "ConcreteClass1";
}
public function prefixValue($prefix) {
return "{$prefix}ConcreteClass1";
}
}
$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue('FOO_') ."<br/>";
//Fatal error: Access level to ConcreteClass1::getValue() must be public (as in class AbstractClass)
6. Signatures of the abstract methods must match:When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child;the signatures of the methods must match, i.e. the type hints and the number of required arguments must be the same. For example, if the child class defines an optional argument, where the abstract method's signature does not, there is no conflict in the signature.
abstract class AbstractClass
{
abstract protected function prefixName($name);
}
class ConcreteClass extends AbstractClass
{
public function prefixName($name, $separator = ".") {
if ($name == "Pacman") {
$prefix = "Mr";
} elseif ($name == "Pacwoman") {
$prefix = "Mrs";
} else {
$prefix = "";
}
return "{$prefix}{$separator} {$name}";
}
}
$class = new ConcreteClass;
echo $class->prefixName("Pacman"), "<br/>";
echo $class->prefixName("Pacwoman"), "<br/>";
//output: Mr. Pacman
// Mrs. Pacwoman
7. Abstract class doesn't support multiple inheritance:Abstract class can extends another abstract class,Abstract class can provide the implementation of interface.But it doesn't support multiple inheritance.
interface MyInterface{
public function foo();
public function bar();
}
abstract class MyAbstract1{
abstract public function baz();
}
abstract class MyAbstract2 extends MyAbstract1 implements MyInterface{
public function foo(){ echo "foo"; }
public function bar(){ echo "bar"; }
public function baz(){ echo "baz"; }
}
class MyClass extends MyAbstract2{
}
$obj=new MyClass;
$obj->foo();
$obj->bar();
$obj->baz();
//output: foobarbaz
Note: Please note order or positioning of the classes in your code can affect the interpreter and can cause a Fatal error. So, when using multiple levels of abstraction, be careful of the positioning of the classes within the source code.
below example will cause Fatal error: Class 'horse' not found
class cart extends horse {
public function get_breed() { return "Wood"; }
}
abstract class horse extends animal {
public function get_breed() { return "Jersey"; }
}
abstract class animal {
public abstract function get_breed();
}
$cart = new cart();
print($cart->get_breed());
Collections.sort(teamsName.subList(1, teamsName.size()));
The code above will reflect the actual sublist of your original list sorted.
Note: imp is deprecated since Python 3.4 in favor of importlib
As mentioned the imp module provides you loading functions:
imp.load_source(name, path)
imp.load_compiled(name, path)
I've used these before to perform something similar.
In my case I defined a specific class with defined methods that were required. Once I loaded the module I would check if the class was in the module, and then create an instance of that class, something like this:
import imp
import os
def load_from_file(filepath):
class_inst = None
expected_class = 'MyClass'
mod_name,file_ext = os.path.splitext(os.path.split(filepath)[-1])
if file_ext.lower() == '.py':
py_mod = imp.load_source(mod_name, filepath)
elif file_ext.lower() == '.pyc':
py_mod = imp.load_compiled(mod_name, filepath)
if hasattr(py_mod, expected_class):
class_inst = getattr(py_mod, expected_class)()
return class_inst
From angular 7 and up, since ngModel is deprecated, we can simply use the control to get the new selected value very easily in a reactive way.
Example:
<form [formGroup]="frmMyForm">
<select class="form-control" formControlName="fieldCtrl">
<option value=""></option>
<option value="val1">label val 1</option>
<option value="val2">label val 2</option>
<option value="val3">label val 3</option>
</select>
</form>
this.frmMyForm.get('fieldCtrl').valueChanges.subscribe( value => {
this.selectedValue = value;
});
By using this fully reactive way, we can upgrade older angular application version to newer ones more easily.
If you want formated number then use
SELECT TO_CHAR(number, 'fmt')
FROM DUAL;
SELECT TO_CHAR('123', 999.99)
FROM DUAL;
Result 123.00
If you want easy to use libraries, you can use the NUGET packages:
Note these are 3rd-Party packages - you can use them for basic functionality for free, but if you want more features there might be a "pro" version.
They are using a two-dimensional object array (i.e. object[][] cells
) to read / write data.
Thread safe simply means that it may be used from multiple threads at the same time without causing problems. This can mean that access to any resources are synchronized, or whatever.
If the JSON data in your array is sorted in some way, there are a variety of searches you could implement. However, if you're not dealing with a lot of data then you're probably going to be fine with an O(n) operation here (as you have). Anything else would probably be overkill.

The lambda you pass to Where
can include any normal C# code, for example the &&
operator:
.Where(l => l.Title != string.Empty && l.InternalName != string.Empty)
Html Code:
<select id="multiple" multiple="multiple" name="multiple">
<option value=""> -- Select -- </option>
<option value="1">Opt1</option>
<option value="2">Opt2</option>
<option value="3">Opt3</option>
<option value="4">Opt4</option>
<option value="5">Opt5</option>
</select>
JQuery Code:
$('#multiple :selected').each(function(i, sel){
alert( $(sel).val() );
});
Hope it works
For the parent:
display: flex;
You should add some prefixes http://css-tricks.com/using-flexbox/
Edit: Only drawback is IE as usual, IE9 does not support flex. http://caniuse.com/flexbox
Edit 2: As @toddsby noted, align items is for parent, and its default value actually is stretch. If you want a different value for child, there is align-self property.

Alternatively, to change all characters except numbers and letters, try:

Since JDK 11:
String file = ...
Path path = Paths.get(file);

// Or readString(path, someCharset), if you need a Charset different from UTF-8
For my university project, I was looking for a parser / evaluator supporting both basic formulas and more complicated equations (especially iterated operators). I found very nice open source library for JAVA and .NET called mXparser. I will give a few examples to make some feeling on the syntax, for further instructions please visit project website (especially tutorial section).
https://mathparser.org/mxparser-tutorial/
And few examples
1 - Simple furmula
Expression e = new Expression("( 2 + 3/4 + sin(pi) )/2");
double v = e.calculate()
2 - User defined arguments and constants
Argument x = new Argument("x = 10");
Constant a = new Constant("a = pi^2");
Expression e = new Expression("cos(a*x)", x, a);
double v = e.calculate()
3 - User defined functions
Function f = new Function("f(x, y, z) = sin(x) + cos(y*z)");
Expression e = new Expression("f(3,2,5)", f);
double v = e.calculate()
4 - Iteration
Expression e = new Expression("sum( i, 1, 100, sin(i) )");
double v = e.calculate()
Found recently - in case you would like to try the syntax (and see the advanced use case) you can download the Scalar Calculator app that is powered by mXparser.

For the error 5, i did the opposite to the solution above. "The first Error 5: Access Denied error was resolved by giving permissions to the output directory to the NETWORK SERVICE account."
I changed mine to local account, instead of network service account, and because i was logged in as administrator it worked
I had a very similar problem. The goal was to mock a service that persists Objects and can return them by their name. The service looks like this:
public class RoomService {
public Room findByName(String roomName) {...}
public void persist(Room room) {...}
}
The service mock uses a map to store the Room instances.
RoomService roomService = mock(RoomService.class);
final Map<String, Room> roomMap = new HashMap<String, Room>();
// mock for method persist
doAnswer(new Answer<Void>() {
@Override
public Void answer(InvocationOnMock invocation) throws Throwable {
Object[] arguments = invocation.getArguments();
if (arguments != null && arguments.length > 0 && arguments[0] != null) {
Room room = (Room) arguments[0];
roomMap.put(room.getName(), room);
}
return null;
}
}).when(roomService).persist(any(Room.class));
// mock for method findByName
when(roomService.findByName(anyString())).thenAnswer(new Answer<Room>() {
@Override
public Room answer(InvocationOnMock invocation) throws Throwable {
Object[] arguments = invocation.getArguments();
if (arguments != null && arguments.length > 0 && arguments[0] != null) {
String key = (String) arguments[0];
if (roomMap.containsKey(key)) {
return roomMap.get(key);
}
}
return null;
}
});
We can now run our tests on this mock. For example:
String name = "room";
Room room = new Room(name);
roomService.persist(room);
assertThat(roomService.findByName(name), equalTo(room));
assertNull(roomService.findByName("none"));
There is a bot that echoes your chat id upon starting a conversation.
Just search for @chatid_echo_bot
and tap /start
. It will echo your chat id.
Another option is @getidsbot
which gives you much more information. This bot also gives information about a forwarded message (from user, to user, chad ids, etc) if you forward the message to the bot.
I just had the same problem. It is not a network permission but rather thread issue. Below code helped me to solve it. Put is in main activity
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (android.os.Build.VERSION.SDK_INT > 9)
{
StrictMode.ThreadPolicy policy = new
StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
I've found the Sync with Active Document
button in the solution explorer to be the the most effective (this may be a vs2013 feature!)
in my case, the war file generated didn't pick up the properties file so had to clean install again in IntelliJ editor.
Just an enhancement to the existing answer.
CGPoint bottomOffset = CGPointMake(0, self.scrollView.contentSize.height - self.scrollView.bounds.size.height + self.scrollView.contentInset.bottom);
[self.scrollView setContentOffset:bottomOffset animated:YES];
It takes care of the bottom inset as well (in case you're using that to adjust your scroll view when the keyboard is visible)
You should be able to do this with a pretty standard DAO recordset loop. You can see some examples at the following links:
http://msdn.microsoft.com/en-us/library/bb243789%28v=office.12%29.aspx
http://www.granite.ab.ca/access/email/recordsetloop.htm
My own standard loop looks something like this:
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM Contacts")
'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
rs.MoveFirst 'Unnecessary in this case, but still a good habit
Do Until rs.EOF = True
'Perform an edit
rs.Edit
rs!VendorYN = True
rs("VendorYN") = True 'The other way to refer to a field
rs.Update
'Save contact name into a variable
sContactName = rs!FirstName & " " & rs!LastName
'Move to the next record. Don't ever forget to do this.
rs.MoveNext
Loop
Else
MsgBox "There are no records in the recordset."
End If
MsgBox "Finished looping through records."
rs.Close 'Close the recordset
Set rs = Nothing 'Clean up
This finally became a part of support v4 library, NestedScrollView. So, no longer local hacks is needed for most of cases I'd guess.
There is no difference in terms of functionality
The addwithvalue
method takes an object as the value. There is no type data type checking. Potentially, that could lead to error if data type does not match with SQL table. The add
method requires that you specify the Database type first. This helps to reduce such errors.

OK, we may get confused when we hear about null
and undefined
, but let's start it simple, they both are falsy and similar in many ways, but weird part of JavaScript, make them a couple of significant differences, for example, typeof null
is 'object'
while typeof undefined
is 'undefined'
.
typeof null; //"object"
typeof undefined; //"undefined";
But if you check them with ==
as below, you see they are both falsy:
null==undefined; //true
Also you can assign null
to an object property or to a primitive, while undefined
can simply be achieved by not assigning to anything.
I create a quick image to show the differences for you at a glance.
I think you're not using GROUP BY properly.
The point of GROUP BY is to organize your table into sections based off a certain column or columns before performing math/aggregate functions.
For example, in this table:
Name Age Salary
Bob 25 20000
Sally 42 40000
John 42 90000
A SELECT statement could GROUP BY name (Bob, Sally, and John would each be separate groups), Age (Bob would be one group, Sally and John would be another), or Salary (pretty much same result as name).
Grouping by "1" doesn't make any sense because "1" is not a column name.
SELECT
(select count(*) from foo1 where ID = '00123244552000258')
+
(select count(*) from foo2 where ID = '00123244552000258')
+
(select count(*) from foo3 where ID = '00123244552000258')
This is an easy way.
You need to load your JNI library.
System.loadLibrary loads the DLL from the JVM path (JDK bin path).
If you want to load an explicit file with a path, use System.load()
See also: Difference between System.load() and System.loadLibrary in Java
For this purpose, you can use git-extras
$ git delete-merged-branches
Deleted feature/themes (was c029ab3).
Deleted feature/live_preview (was a81b002).
Deleted feature/dashboard (was 923befa).
you can use Intent for this:
Intent browserIntent = new Intent("android.intent.action.VIEW", Uri.parse("your Url"));
startActivity(browserIntent);
There are a couple of things you can't do with a primitive type:
null
valueObject
sUnless you need any of those, you should prefer primitive types, since they require less memory.
That should work. Better if you pass a function to val
:
$('#replyBox').val(function(i, text) {
return text + quote;
});
This way you avoid searching the element and calling val
twice.
This could be added to the accepted answer for a 'cross-browser' solution.

The most common way of doing this is to include the binary as base-64 in an element. However, this is a workaround, and adds a bit of volume to the file.
For example, this is the bytes 00 to 09 (note we needed 16 bytes to encode 10 bytes worth of data):
<xml><image>AAECAwQFBgcICQ==</image></xml>
how you do this encoding varies per architecture. For example, with .NET you might use Convert.ToBase64String
, or XmlWriter.WriteBase64
.
Try putting your text in another div inside your span:
i.e.

@Vel Genov's answer is correct, except when the version of Xcode can't be updated because it is the latest version for your current version of Mac OS. If you know there is a newer Xcode (for example, it won't load an app onto a device with a recent version of iOS) then it's necessary to first upgrade Mac OS.
Further note for those like me with old Mac Pro 5.1. Upgrading to Mojave required installing the metal gpu (Sapphire AMD Radeon RX 560 in my case) but make sure only HDMI monitor is installed (not 4K! 1080 only). Only then did install Mojave say firmware update required and shut computer down. Long 2 minute power button hold and it all upgraded fine after that!

You can't declare an extern
local method inside of a method, or any other method with an attribute. Move your DLL import into the class:
using System.Runtime.InteropServices;
public class WindowHandling
{
[DllImport("User32.dll")]
public static extern int SetForegroundWindow(IntPtr point);
public void ActivateTargetApplication(string processName, List<string> barcodesList)
{
Process p = Process.Start("notepad++.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
IntPtr processFoundWindow = p.MainWindowHandle;
}
}
When your class implements Comparable, the compareTo
method of the class is defining the "natural" ordering of that object. That method is contractually obligated (though not demanded) to be in line with other methods on that object, such as a 0 should always be returned for objects when the .equals()
comparisons return true.
A Comparator is its own definition of how to compare two objects, and can be used to compare objects in a way that might not align with the natural ordering.
For example, Strings are generally compared alphabetically. Thus the "a".compareTo("b")
would use alphabetical comparisons. If you wanted to compare Strings on length, you would need to write a custom comparator.
In short, there isn't much difference. They are both ends to similar means. In general implement comparable for natural order, (natural order definition is obviously open to interpretation), and write a comparator for other sorting or comparison needs.
Here's a useful of an open source game that uses a lot of collisions: http://robocode.sourceforge.net/
You may take a look at the code and complement with the answers written here.
While iterating over a list or array with this method:
ar = [10, 11, 12]
for i in ar:
theSum = theSum + ar[i]
You are actually getting the values of list or array sequentially in i
variable.
If you print the variable i
inside the for loop
. You will get following output:
10
11
12
However, in your code you are confusing i
variable with index value of array. Therefore, while doing ar[i]
will mean ar[10]
for the first iteration. Which is of course index out of range throwing IndexError
Edit You can read this for better understanding of different methods of iterating over array or list in Python
This is how to use chai to deeply test associative arrays.
I had an issue trying to assert that two associative arrays were equal. I know that these shouldn't really be used in javascript but I was writing unit tests around legacy code which returns a reference to an associative array. :-)
I did it by defining the variable as an object (not array) prior to my function call:
var myAssocArray = {}; // not []
var expectedAssocArray = {}; // not []
expectedAssocArray['myKey'] = 'something';
expectedAssocArray['differentKey'] = 'something else';
// legacy function which returns associate array reference
myFunction(myAssocArray);
assert.deepEqual(myAssocArray, expectedAssocArray,'compare two associative arrays');
The return type of a procedure is int.
You can also return result sets (as your code currently does) (okay, you can also send messages, which are strings)
Those are the only "returns" you can make. Whilst you can add table-valued parameters to a procedure (see BOL), they're input only.
Edit:
(Or as another poster mentioned, you could also use a Table Valued Function, rather than a procedure)
I know this is an older post, but it helped me out. I've also found that for bootstrap v4 you can also change the arrow color by overriding the controls like this:
.carousel-control-prev-icon {
background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E") !important;
}
.carousel-control-next-icon {
background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M2.75 0l-1.5 1.5 2.5 2.5-2.5 2.5 1.5 1.5 4-4-4-4z'/%3E%3C/svg%3E") !important;
}
Where you change fill='%23fff'
the fff at the end to any hexadecimal value that you want. For example:
fill='%23000'
for black, fill='%23ff0000'
for red and so on. Just a note, I haven't tested this without the !important declaration.
try this:
/////// Controller post and get simple text value
[HttpPost]
public string Contact(string message)
{
return "<h1>Hi,</h1>we got your message, <br />" + message + " <br />Thanks a lot";
}
//// in the view add reference to the Javascript (jQuery) files
@section Scripts{
<script src="~/Scripts/modernizr-2.6.2.js"></script>
<script src="~/Scripts/jquery-1.8.2.intellisense.js"></script>
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
}
/// then add the Post method as following:
<script type="text/javascript">
/// post and get text value
$("#send").on("click", function () {
$.post('', { message: $('#msg').val() })
//// empty post('') means post to the default controller,
///we are not pacifying different action or controller
/// however we can define a url as following:
/// var url = "@(Url.Action("GetDataAction", "GetDataController"))"
.done(function (response) {
$("#myform").html(response);
})
.error(function () { alert('Error') })
.success(function () { alert('OK') })
return false;
});
Now let's say you want to do it using $.Ajax and JSON:
// Post JSON data add using System.Net;
[HttpPost]
public JsonResult JsonFullName(string fname, string lastname)
{
var data = "{ \"fname\" : \"" + fname + " \" , \"lastname\" : \"" + lastname + "\" }";
//// you have to add the JsonRequestBehavior.AllowGet
//// otherwise it will throw an exception on run-time.
return Json(data, JsonRequestBehavior.AllowGet);
}
Then, inside your view: add the event click on a an input of type button, or even a from submit: Just make sure your JSON data is well formatted.
$("#jsonGetfullname").on("click", function () {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "@(Url.Action("JsonFullName", "Home"))",
data: "{ \"fname\" : \"Mahmoud\" , \"lastname\" : \"Sayed\" }",
dataType: "json",
success: function (data) {
var res = $.parseJSON(data);
$("#myform").html("<h3>Json data: <h3>" + res.fname + ", " + res.lastname)
},
error: function (xhr, err) {
alert("readyState: " + xhr.readyState + "\nstatus: " + xhr.status);
alert("responseText: " + xhr.responseText);
}
})
});

To test without copy elision and see you copy/move constructors/operators in action add "-fno-elide-constructors".
Even with no optimizations (-O0 ), GCC and Clang will still do copy elision, which has the effect of skipping copy/move constructors in some cases. See this question for the details about copy elision.
However, in Clang 3.4 it does trigger a bug (an invalid temporary object without calling constructor), which is fixed in 3.5.
Using pdfbox we can achive this
Example :
public static void main(String args[]) {
PDFParser parser = null;
PDDocument pdDoc = null;
COSDocument cosDoc = null;
PDFTextStripper pdfStripper;
String parsedText;
String fileName = "E:\\Files\\Small Files\\PDF\\JDBC.pdf";
File file = new File(fileName);
try {
parser = new PDFParser(new FileInputStream(file));
parser.parse();
cosDoc = parser.getDocument();
pdfStripper = new PDFTextStripper();
pdDoc = new PDDocument(cosDoc);
parsedText = pdfStripper.getText(pdDoc);
System.out.println(parsedText.replaceAll("[^A-Za-z0-9. ]+", ""));
} catch (Exception e) {
e.printStackTrace();
try {
if (cosDoc != null)
cosDoc.close();
if (pdDoc != null)
pdDoc.close();
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
I managed to fix it :D heres the code.
var divh = document.getElementById('first').offsetHeight;
$("#first").css('height', '100px');
$("div:first").click(function() {
$("#first").animate({
height: divh
}, 1000);
});
In earlier versions of NPM modules were always placed in /usr/local/lib/node or wherever you specified the npm root within the .npmrc file. However, in NPM 1.0+ modules are installed in two places. You can have modules installed local to your application in /.node_modules or you can have them installed globally which will use the above.
More information can be found at https://github.com/isaacs/npm/blob/master/doc/install.md
The targetNamespace
of your XML Schema does not match the namespace of the Root element (dot in Test.Namespace
vs. comma in Test,Namespace
)
Once you make the above agree, you have to consider that your element2
has an attribute order that is not in your XSD.
From the command line it would be just:
svn update
(in the directory you've got a copy of a SVN project).
I've seen a lot of examples that use "break" but none that use "continue".
It still would require a flag of some sort in the inner loop:
while( some_condition )
{
// outer loop stuff
...
bool get_out = false;
for(...)
{
// inner loop stuff
...
get_out = true;
break;
}
if( get_out )
{
some_condition=false;
continue;
}
// more out loop stuff
...
}
To perform a linear regression between two vectors x
and y
follow these steps:
[p,err] = polyfit(x,y,1); % First order polynomial
y_fit = polyval(p,x,err); % Values on a line
y_dif = y - y_fit; % y value difference (residuals)
SSdif = sum(y_dif.^2); % Sum square of difference
SStot = (length(y)-1)*var(y); % Sum square of y taken from variance
rsq = 1-SSdif/SStot; % Correlation 'r' value. If 1.0 the correlelation is perfect
For x=[10;200;7;150]
and y=[0.001;0.45;0.0007;0.2]
I get rsq = 0.9181
.

This is excellent practice.
By creating variables inside loops, you ensure their scope is restricted to inside the loop. It cannot be referenced nor called outside of the loop.
This way:
If the name of the variable is a bit "generic" (like "i"), there is no risk to mix it with another variable of same name somewhere later in your code (can also be mitigated using the -Wshadow
warning instruction on GCC)
The compiler knows that the variable scope is limited to inside the loop, and therefore will issue a proper error message if the variable is by mistake referenced elsewhere.
Last but not least, some dedicated optimization can be performed more efficiently by the compiler (most importantly register allocation), since it knows that the variable cannot be used outside of the loop. For example, no need to store the result for later re-use.
In short, you are right to do it.
Note however that the variable is not supposed to retain its value between each loop. In such case, you may need to initialize it every time. You can also create a larger block, encompassing the loop, whose sole purpose is to declare variables which must retain their value from one loop to another. This typically includes the loop counter itself.
{
int i, retainValue;
for (i=0; i<N; i++)
{
int tmpValue;
/* tmpValue is uninitialized */
/* retainValue still has its previous value from previous loop */
/* Do some stuff here */
}
/* Here, retainValue is still valid; tmpValue no longer */
}
For question #2: The variable is allocated once, when the function is called. In fact, from an allocation perspective, it is (nearly) the same as declaring the variable at the beginning of the function. The only difference is the scope: the variable cannot be used outside of the loop. It may even be possible that the variable is not allocated, just re-using some free slot (from other variable whose scope has ended).
With restricted and more precise scope come more accurate optimizations. But more importantly, it makes your code safer, with less states (i.e. variables) to worry about when reading other parts of the code.
This is true even outside of an if(){...}
block. Typically, instead of :
int result;
(...)
result = f1();
if (result) then { (...) }
(...)
result = f2();
if (result) then { (...) }
it's safer to write :
(...)
{
int const result = f1();
if (result) then { (...) }
}
(...)
{
int const result = f2();
if (result) then { (...) }
}
The difference may seem minor, especially on such a small example.
But on a larger code base, it will help : now there is no risk to transport some result
value from f1()
to f2()
block. Each result
is strictly limited to its own scope, making its role more accurate. From a reviewer perspective, it's much nicer, since he has less long range state variables to worry about and track.
Even the compiler will help better : assuming that, in the future, after some erroneous change of code, result
is not properly initialized with f2()
. The second version will simply refuse to work, stating a clear error message at compile time (way better than run time). The first version will not spot anything, the result of f1()
will simply be tested a second time, being confused for the result of f2()
.
The open-source tool CppCheck (a static analysis tool for C/C++ code) provides some excellent hints regarding optimal scope of variables.
In response to comment on allocation: The above rule is true in C, but might not be for some C++ classes.
For standard types and structures, the size of variable is known at compilation time. There is no such thing as "construction" in C, so the space for the variable will simply be allocated into the stack (without any initialization), when the function is called. That's why there is a "zero" cost when declaring the variable inside a loop.
However, for C++ classes, there is this constructor thing which I know much less about. I guess allocation is probably not going to be the issue, since the compiler shall be clever enough to reuse the same space, but the initialization is likely to take place at each loop iteration.
It's not quite what you want, but it's possible using modern javascript to create an EML file on the client and stream that to the user's file system, which should open a rich email containing HTML in their mail program, such as Outlook:

Javascript
(function () {
var textFile = null,
makeTextFile = function (text) {
var data = new Blob([text], {type: 'text/plain'});
if (textFile !== null) {
window.URL.revokeObjectURL(textFile);
}
textFile = window.URL.createObjectURL(data);
return textFile;
};
var create = document.getElementById('create'),
textbox = document.getElementById('textbox');
create.addEventListener('click', function () {
var link = document.getElementById('downloadlink');
link.href = makeTextFile(textbox.value);
link.style.display = 'block';
}, false);
})();
Writing the followin code to print anything on LogCat works perfectly fine!!
int score=0;
score++;
System.out.println(score);
prints score on LogCat.Try this
So you are doing this a bit backwards. Typically you'd do something like this:
?<div class='article'>
Article 1
</div>
<div class='article'>
Article 2
</div>
<div class='article'>
Article 3
</div>?
And then in your jQuery:
$('.article').click(function(){
article = $(this).text(); //$(this) is what you clicked!
});?
When I see things like #search-item .search-article
, #search-item .search-article
, and #search-item .search-article
I sense you are overspecifying your CSS which makes writing concise jQuery very difficult. This should be avoided if at all possible.
