The reason why your image is resizing which is because it is fluid. You have two ways to do it:
Either give a fixed dimension to your image using CSS like:
.carousel-inner > .item > img { width:640px; height:360px; }
A second way to can do this:
.carousel { width:640px; height:360px; }
I use cmder
(a command line emulator)
It allows you to run all Linux commands inside a Windows machine.
It can be downloaded from https://cmder.net/
I really like it
Here is example of pseudo-random generator when neither $RANDOM nor /dev/urandom is available
echo $(date +%S) | grep -o .$ | sed s/0/10/
Here is a generic script you can use in SQL server. just amend the start and end dates:
IF EXISTS (SELECT * FROM information_schema.tables WHERE Table_Name = 'Calendar' AND Table_Type = 'BASE TABLE')
BEGIN
DROP TABLE [Calendar]
END
CREATE TABLE [Calendar]
(
[CalendarDate] DATETIME
)
DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = GETDATE()
SET @EndDate = DATEADD(d, 365, @StartDate)
WHILE @StartDate <= @EndDate
BEGIN
INSERT INTO [Calendar]
(
CalendarDate
)
SELECT
@StartDate
SET @StartDate = DATEADD(dd, 1, @StartDate)
END
If you want a more advanced calendar here is one I found on the net a while ago:

Well firstly C doesn't have public/private/virtual functions. That's C++ and it has different conventions. In C typically you have:
C++ is more complex. I've seen a real mix here. Camel case for class names or lowercase+underscores (camel case is more common in my experience). Structs are used rarely (and typically because a library requires them, otherwise you'd use classes).
echo 0.0.0.0 websitename.com >> %WINDIR%\System32\Drivers\Etc\Hosts
the >>
appends the output of echo
to the file.
Note that there are two reasons this might not work like you want it to. You may be aware of these, but I mention them just in case.
First, it won't affect a web browser, for example, that already has the current, "real" IP address resolved. So, it won't always take effect right away.
Second, it requires you to add an entry for every host name on a domain; just adding websitename.com
will not block www.websitename.com
, for example.
If you are using (org.springframework.jdbc.datasource.DriverManagerDataSource)
in ApplicationContext.xml
to specify Database details then use below simple property to specify the schema.
<property name="schema" value="schemaName" />
infowindow is local variable and window is not available at time of close()
var latlng = new google.maps.LatLng(-34.397, 150.644);
var infowindow = null;
...
google.maps.event.addListener(marker, 'click', function() {
if (infowindow) {
infowindow.close();
}
infowindow = new google.maps.InfoWindow();
...
});
...
Yes. Although I use the following code.
.carousel.fade
{
opacity: 1;
.item
{
-moz-transition: opacity ease-in-out .7s;
-o-transition: opacity ease-in-out .7s;
-webkit-transition: opacity ease-in-out .7s;
transition: opacity ease-in-out .7s;
left: 0 !important;
opacity: 0;
top:0;
position:absolute;
width: 100%;
display:block !important;
z-index:1;
&:first-child{
top:auto;
position:relative;
}
&.active
{
opacity: 1;
-moz-transition: opacity ease-in-out .7s;
-o-transition: opacity ease-in-out .7s;
-webkit-transition: opacity ease-in-out .7s;
transition: opacity ease-in-out .7s;
z-index:2;
}
}
}
Then change the class on the carousel from "carousel slide" to "carousel fade". This works in safari, chrome, firefox, and IE 10. It will correctly downgrade in IE 9, however, the nice face effect doesn't happen.
Edit: Since this answer has gotten so popular I've added the following which rewritten as pure CSS instead of the above which was LESS:
.carousel.fade {
opacity: 1;
}
.carousel.fade .item {
-moz-transition: opacity ease-in-out .7s;
-o-transition: opacity ease-in-out .7s;
-webkit-transition: opacity ease-in-out .7s;
transition: opacity ease-in-out .7s;
left: 0 !important;
opacity: 0;
top:0;
position:absolute;
width: 100%;
display:block !important;
z-index:1;
}
.carousel.fade .item:first-child {
top:auto;
position:relative;
}
.carousel.fade .item.active {
opacity: 1;
-moz-transition: opacity ease-in-out .7s;
-o-transition: opacity ease-in-out .7s;
-webkit-transition: opacity ease-in-out .7s;
transition: opacity ease-in-out .7s;
z-index:2;
}
After a lot of time spent trying all these technique in a Dialog, I finally had this idea : attach the theme to the Dialog itself and not to the TextInputLayout.
<style name="AppTheme_Dialog" parent="Theme.AppCompat.Dialog">
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorWhite</item>
<item name="colorAccent">@color/colorPrimary</item>
</style>
inside onCreate :
public class myDialog extends Dialog {
private Activity activity;
private someVars;
public PopupFeedBack(Activity activity){
super(activity, R.style.AppTheme_Dialog);
setContentView(R.layout.myView);
....}}
cheers :)

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.
var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

HTML5 introduced a file upload api that allows you to monitor the progress of file uploads but for older browsers there's plupload a framework that specifically made to monitor file uploads and give information about them. plus it has plenty of callbacks so it can work across all browsers
Use this one to change only font size not the name of the font
label1.Font = new System.Drawing.Font(label1.Font.Name, 24F);
This usually happens to me if I misplace a return statement, for example:
Adding a return statement, or in my case, moving it to correct scope will do the trick:
Swift 4.2 , In my case , using isKind function .
isKind(of:) Returns a Boolean value that indicates whether the receiver is an instance of given class or an instance of any class that inherits from that class.
let items : [AnyObject] = ["A", "B" , ... ]
for obj in items {
if(obj.isKind(of: NSString.self)){
print("String")
}
}

Use #pragma warning ( push )
, then #pragma warning ( disable )
, then put your code, then use #pragma warning ( pop )
as described here:
#pragma warning( push )
#pragma warning( disable : WarningCode)

You can also try this one if u need it in almost all places in the page.
U can configure it in a general way then just use it.
In this way u can also use HTML element and anything u want :)

Even more can be found here.
If u want the popup after click, u can change the JS option to trigger: "click"
like this-
return ..;

, trigger: "click"
......
};
U also can customize it in HTML ading data-trigger="click"
like this-
<a id="try_ppover" href="#" data-toggle="popover" data-trigger="click" title="Popover Header" data-content="<div class='jumbotron'>Some content inside the popover</div>">Toggle popover</a>
I think it will be more oriented code and more re-usable and more helpful to all :).
The accepted answer didn't work for me as my page jumped slightly on click, messing up my scroll animation.
I decided to update the entire URL using window.history.replaceState
rather than using the window.location.hash
method. Thus circumventing the hashChange event fired by the browser.
// Only fire when URL has anchor
$('a[href*="#"]:not([href="#"])').on('click', function(event) {
// Prevent default anchor handling (which causes the page-jumping)
event.preventDefault();
if ( location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname ) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if ( target.length ) {
// Smooth scrolling to anchor
$('html, body').animate({
scrollTop: target.offset().top
}, 1000);
// Update URL
window.history.replaceState("", document.title, window.location.href.replace(location.hash, "") + this.hash);
}
}
});
This works for me:
scrollview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
scrollview.post(new Runnable() {
public void run() {
scrollview.fullScroll(View.FOCUS_DOWN);
}
});
}
});
In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.
In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.
With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.
One option is to put the subquery in a LEFT JOIN
:
select sum ( t.graduates ) - t1.summedGraduates
from table as t
left join
(
select sum ( graduates ) summedGraduates, id
from table
where group_code not in ('total', 'others' )
group by id
) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates
Perhaps a better option would be to use SUM
with CASE
:
select sum(case when group_code = 'total' then graduates end) -
sum(case when group_code not in ('total','others') then graduates end)

If you installed xcode and upgraded to mountain lion, or you don't have the latest command line tools installed, or you have zsh or other shells, you can shortcut to some of the embedded tools in the developer directory with:
xcrun make
You can also use google-collections (guava) Joiner class if you want to customize the print format
Gson 1.6 now includes a low-level streaming API and a new parser which is actually faster than Jackson.
The source tree you are requiring is still available within the git repository, however, you will need the SHA1 of the commit that you are interested in. I would assume that you can get the SHA1 from the current clone you have?
If you can get that SHA1, the you can create a branch / reset there to have the identical repository.

Had same problem. Just did a quick look up apache2 error.log
file and it said exactly what was the problem:
> sh: /usr/sbin/sendmail: Permission denied
So, the solution was to give proper permissions for /usr/sbin/sendmail
file (it wasn't accessible from php).
Command to do this would be:
> chmod 777 /usr/sbin/sendmail
be sure that it even exists!
Try this one to push basic authentication at url:
curl -i http://username:[email protected]/api/users -H "Authorization: Bearer mytoken123"
^^^^^^^^^^^^^^^^^^
If above one doesn't work, then you have nothing to do with it. So try the following alternates.
You can pass the token under another name. Because you are handling the authorization from your Application. So you can easily use this flexibility for this special purpose.
curl -i http://dev.myapp.com/api/users \
-H "Authorization: Basic Ym9zY236Ym9zY28=" \
-H "Application-Authorization: mytoken123"
Notice I have changed the header into Application-Authorization
. So from your application catch the token under that header and process what you need to do.
Another thing you can do is, to pass the token
through the POST
parameters and grab the parameter's value from the Server side. For example passing token with curl post parameter:
-d "auth-token=mytoken123"
The reason i could not delete some of the users via 'drop' statement was that there is a bug in Mysql http://bugs.mysql.com/bug.php?id=62255 with hostname containing upper case letters. The solution was running following query:
DELETE FROM mysql.user where host='Some_Host_With_UpperCase_Letters';
I am still trying to figure the other issue where the root user with all permissions are unable to grant privileges to new user for particular database
If there is space between the letters of the font, you need to use quote.

Take a look at the LobBasicSample for an example to use CLOB, BLOB, NLOB datatypes.
Java9 uses byte[] to store String.value, so you can only get about 1GB Strings in Java9. Java8 on the other hand can have 2GB Strings.
By character I mean "char"s, some character is not representable in BMP(like some of the emojis), so it will take more(currently 2) chars.
Obvious caveats aside, if your array was actually like the one above, you could do
if [[ ${arr[*]} =~ d ]]
then

If you don't care about the data, you can drop database first and then recreate it:
DROP DATABASE IF EXISTS dbname;
CREATE DATABASE dbname;
A standard http GET request should do it. Then you can use JSON.parse() to make it into a json object.
function Get(yourUrl){
var Httpreq = new XMLHttpRequest(); // a new request
Httpreq.open("GET",yourUrl,false);
Httpreq.send(null);
return Httpreq.responseText;
}
then
var json_obj = JSON.parse(Get(yourUrl));
console.log("this is the author name: "+json_obj.author_name);
that's basically it
Further, people usually want to remove all *.pyc
, *.pyo
files and __pycache__
directories recursively in the current directory.
Command:
find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf
You can also try Nullable(T) Properties:
DateTime UpdatedTime = _objHotelPackageOrder.UpdatedDate.HasValue
? DateTime.Now : _objHotelPackageOrder.UpdatedDate.Value;
the squeel
gem provides an incredibly easy way to accomplish this (prior to this I used something like @coloradoblue's method):
names = ["Kroger", "Walmart", "Target", "Aldi"]
matching_stores = Grocery.where{name.like_any(names)}

Because someone asked for the Data.Table version of this, and because the given data.frame solution does not work with data.table, I am providing the solution below.
Basically, use the :=

status = as.data.table(occupationalStatus)
head(status, 10)

0 is, by definition, a magic number. EXIT_SUCCESS is almost universally equal to 0, happily enough. So why not just return/exit 0?
exit(EXIT_SUCCESS); is abundantly clear in meaning.
exit(0); on the other hand, is counterintuitive in some ways. Someone not familiar with shell behavior might assume that 0 == false == bad, just like every other usage of 0 in C. But no - in this one special case, 0 == success == good. For most experienced devs, not going to be a problem. But why trip up the new guy for absolutely no reason?
tl;dr - if there's a defined constant for your magic number, there's almost never a reason not to used the constant in the first place. It's more searchable, often clearer, etc. and it doesn't cost you anything.
Change that import to

In my case, another program had added PATH
changes to .bashrc
If the other program changed the PATH
after nvm's initialisation, then nvm's PATH
changes would be forgotten, and we would get the system node on our PATH
(or no node).
The solution was to move the nvm setup to the bottom of .bashrc
### BAD .bashrc ###
# NVM initialisation
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
# Some other program adding to the PATH:
export PATH="$ANT_ROOT:$PATH"
Solution:
### GOOD .bashrc ###
# Some other program adding to the PATH:
export PATH="$ANT_ROOT:$PATH"
# NVM initialisation
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
(This was with bash 4.2.46 on CentOS. It seems to me like a bug in bash, but I may be mistaken.)

boolean right = isBinarySearchTree(node.getRight(), node.getValue(), max);
return left && right && (node.getValue()<max) && (node.getValue()>=min);
}
Hope it will help you. Sorry if i am diverting from the topic as i felt it's worth mentioning this here.

In general you cannot rely on a fixed pixel size for fonts, the user may be scaling the screen and the defaults are not always the same (depends on DPI settings of the screen etc.).
Maybe have a look at this (pixel to point) and this link.
But of course you can set the font size to px, so that you do know how many pixels the font actually is. This may help if you really need a fixed layout, but this practice reduces accessibility of your web site.
Both .container
and .container-fluid
are responsive (i.e. they change the layout based on the screen width), but in different ways (I know, the naming doesn't make it sound that way).
Short Answer:
.container
is jumpy / choppy resizing, and
.container-fluid
is continuous / fine resizing at width: 100%.
From a functionality perspective:
.container-fluid
continuously resizes as you change the width of your window/browser by any amount, leaving no extra empty space on the sides ever, unlike how .container
does. (Hence the naming: "fluid" as opposed to "digital", "discrete", "chunked", or "quantized").
.container
resizes in chunks at several certain widths. In other words, it will be different specific aka "fixed" widths different ranges of screen widths.
Semantics: "fixed width"
You can see how naming confusion can arise. Technically, we can say .container
is "fixed width", but it is fixed only in the sense that it doesn't resize at every granular width. It's actually not "fixed" in the sense that it's always stays at a specific pixel width, since it actually can change size.
From a fundamental perspective:
.container-fluid
has the CSS property width: 100%;
, so it continually readjusts at every screen width granularity.
.container-fluid {
width: 100%;
}
.container
has something like "width = 800px" (or em, rem etc.), a specific pixel width value at different screen widths. This of course is what causes the element width to abruptly jump to a different width when the screen width crosses a screen width threshold. And that threshold is governed by CSS3 media queries, which allow you to apply different styles for different conditions, such as screen width ranges.
@media screen and (max-width: 400px){
.container {
width: 123px;
}
}
@media screen and (min-width: 401px) and (max-width: 800px){
.container {
width: 456px;
}
}
@media screen and (min-width: 801px){
.container {
width: 789px;
}
}
Beyond
You can make any fixed widths element responsive via media queries, not just .container
elements, since media queries is exactly how .container
is implemented by bootstrap in the background (see JKillian's answer for the code).
I got an exception when using rs.last()
if(rs.last()){
rowCount = rs.getRow();
rs.beforeFirst();
}
:
java.sql.SQLException: Invalid operation for forward only resultset
it's due to by default it is ResultSet.TYPE_FORWARD_ONLY

the solution is:
stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
Use the <embed>
element:
<embed src="file.swf" width="854" height="480"></embed>
To simplify the answare let's look on the following code:
#include "stdafx.h"
#include <iostream>
using namespace std;
class A
{
private:
int m_id;
static int count;
public:
A() {count++; m_id = count;}
A(int id) { m_id = id; }
~A() {cout<< "Destructor A " <<m_id<<endl; }
};
int A::count = 0;
void f1()
{
A* arr = new A[10];
//delete operate only one constructor, and crash!
delete arr;
//delete[] arr;
}
int main()
{
f1();
system("PAUSE");
return 0;
}
The output is: Destructor A 1 and then it's crashing (Expression: _BLOCK_TYPE_IS_VALID(phead- nBlockUse)).
We need to use: delete[] arr; becuse it's delete the whole array and not just one cell!
try to use delete[] arr; the output is: Destructor A 10 Destructor A 9 Destructor A 8 Destructor A 7 Destructor A 6 Destructor A 5 Destructor A 4 Destructor A 3 Destructor A 2 Destructor A 1
The same principle is for an array of pointers:
void f2()
{
A** arr = new A*[10];
for(int i = 0; i < 10; i++)
{
arr[i] = new A(i);
}
for(int i = 0; i < 10; i++)
{
delete arr[i];//delete the A object allocations.
}
delete[] arr;//delete the array of pointers
}
if we'll use delete arr instead of delete[] arr. it will not delete the whole pointers in the array => memory leak of pointer objects!
There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.
You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.
When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.
As distributionUrl
is still pointing to older version, upgrade wrapper using:
gradle wrapper --gradle-version 5.1.1

Repetition in regex by default is greedy: they try to match as many reps as possible, and when this doesn't work and they have to backtrack, they try to match one fewer rep at a time, until a match of the whole pattern is found. As a result, when a match finally happens, a greedy repetition would match as many reps as possible.
The ?
as a repetition quantifier changes this behavior into non-greedy, also called reluctant (in e.g. Java) (and sometimes "lazy"). In contrast, this repetition will first try to match as few reps as possible, and when this doesn't work and they have to backtrack, they start matching one more rept a time. As a result, when a match finally happens, a reluctant repetition would match as few reps as possible.
Let's compare these two patterns: A.*Z
and A.*?Z
.
Given the following input:
eeeAiiZuuuuAoooZeeee
The patterns yield the following matches:
A.*Z
yields 1 match: AiiZuuuuAoooZ
(see on rubular.com)A.*?Z
yields 2 matches: AiiZ
and AoooZ
(see on rubular.com)Let's first focus on what A.*Z
does. When it matched the first A
, the .*
, being greedy, first tries to match as many .
as possible.
eeeAiiZuuuuAoooZeeee
\_______________/
A.* matched, Z can't match
Since the Z
doesn't match, the engine backtracks, and .*
must then match one fewer .
:
eeeAiiZuuuuAoooZeeee
\______________/
A.* matched, Z still can't match
This happens a few more times, until finally we come to this:
eeeAiiZuuuuAoooZeeee
\__________/
A.* matched, Z can now match
Now Z
can match, so the overall pattern matches:
eeeAiiZuuuuAoooZeeee
\___________/
A.*Z matched
By contrast, the reluctant repetition in A.*?Z
first matches as few .
as possible, and then taking more .
as necessary. This explains why it finds two matches in the input.
Here's a visual representation of what the two patterns matched:
eeeAiiZuuuuAoooZeeee
\__/r \___/r r = reluctant
\____g____/ g = greedy
In many applications, the two matches in the above input is what is desired, thus a reluctant .*?
is used instead of the greedy .*
to prevent overmatching. For this particular pattern, however, there is a better alternative, using negated character class.
The pattern A[^Z]*Z
also finds the same two matches as the A.*?Z
pattern for the above input (as seen on ideone.com). [^Z]
is what is called a negated character class: it matches anything but Z
.
The main difference between the two patterns is in performance: being more strict, the negated character class can only match one way for a given input. It doesn't matter if you use greedy or reluctant modifier for this pattern. In fact, in some flavors, you can do even better and use what is called possessive quantifier, which doesn't backtrack at all.
This example should be illustrative: it shows how the greedy, reluctant, and negated character class patterns match differently given the same input.
eeAiiZooAuuZZeeeZZfff
These are the matches for the above input:
A[^Z]*ZZ
yields 1 match: AuuZZ
(as seen on ideone.com)A.*?ZZ
yields 1 match: AiiZooAuuZZ
(as seen on ideone.com)A.*ZZ
yields 1 match: AiiZooAuuZZeeeZZ
(as seen on ideone.com)Here's a visual representation of what they matched:
___n
/ \ n = negated character class
eeAiiZooAuuZZeeeZZfff r = reluctant
\_________/r / g = greedy

The spaces are DOSs/CMDs Problems so you should go to the Path via:
cd "c:\program files\Microsoft Virtual PC"
and then simply start VPC via:
start Virtual~1.exe -pc MY-PC -launch
~1
means the first exe
with "Virtual"
at the beginning. So if there is a "Virtual PC.exe"
and a "Virtual PC1.exe"
the first would be the Virtual~1.exe
and the second Virtual~2.exe
and so on.
Or use a VNC-Client like VirtualBox.

Just to expand on an earlier answer, something like this does it for me:
NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"];
Note: This retrieves the "Phone number" that was entered during the iPhone's iTunes activation and can be null or an incorrect value. It's NOT read from the SIM card.
At least that does in 2.1. There are a couple of other interesting keys in NSUserDefaults that may also not last. (This is in my app which uses a UIWebView)
WebKitJavaScriptCanOpenWindowsAutomatically
NSInterfaceStyle

How can I push my tag to the remote repository so that all client computers can see it?
Run this to push mytag
to your git origin (eg: GitHub or GitLab)
git push origin refs/tags/mytag
It's better to use the full "refspec" as shown above (literally refs/tags/mytag
) just in-case mytag
is actually v1.0.0
and is ambiguous (eg: because there's a branch also named v1.0.0
).
A tar.gz is a tar file inside a gzip file, so 1st you must unzip the gzip file with gunzip -d filename.tar.gz
, and then use tar
to untar it. However, since gunzip
says it isn't in gzip format, you can see what format it is in with file filename.tar.gz
, and use the appropriate program to open it.
If you don't want to generate and store the file on the server, are you willing to store the status, e.g. file-in-progress, file-complete? Your "waiting" page could poll the server to know when the file generation is complete. You wouldn't know for sure that the browser started the download but you'd have some confidence.
It is terrible, but you can try to use
select
SUBSTRING(Table1.Col1,0,PATINDEX('%|%=',Table1.Col1)) as myString
from
Table1
This code is probably not 100% right though. need to be adjusted
It is a C extension from the GCC compiler , see http://gcc.gnu.org/onlinedocs/gcc/Typeof.html
It's a matter of preference, but I prefer to see scripts that consistently use the slash - this way all "units" of work (creating a PL/SQL object, running a PL/SQL anonymous block, and executing a DML statement) can be picked out more easily by eye.
Also, if you eventually move to something like Ant for deployment it will simplify the definition of targets to have a consistent statement delimiter.
Extension to parse decimal number from string.

My fix for IE10 + IE11. Basically what happens is that you add a DIV within an wrapping-element that has to be recalculated. Then just remove it and voila; works like a charm :)
_initForceBrowserRepaint: function() {
$('#wrapper').append('<div style="width=100%" id="dummydiv"></div>');
$('#dummydiv').width(function() { return $(this).width() - 1; }).width(function() { return $(this).width() + 1; });
$('#dummydiv').remove();
},
You'll get that error once your numbers are greater than sys.maxsize
:
>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long
You can confirm this by checking:
>>> import sys
>>> sys.maxsize
2147483647
To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:
>>> preds = np.zeros((1, 3))
You need to install ENU\x64\SQLEXPRWT_x64_ENU.exe which is Express with Tools (RTM release. SP1 release can be found here).
As the page states
Express with Tools (with LocalDB) Includes the database engine and SQL Server Management Studio Express) This package contains everything needed to install and configure SQL Server as a database server. Choose either LocalDB or Express depending on your needs above.
So install this and use the management studio included with it.

Since JPA 2.0 a TypedQuery
can be used:
TypedQuery<SimpleEntity> q =
em.createQuery("select t from SimpleEntity t", SimpleEntity.class);
List<SimpleEntity> listOfSimpleEntities = q.getResultList();
for (SimpleEntity entity : listOfSimpleEntities) {
// do something useful with entity;
}
There is a way with struct namespace.
The benefit is all enum variables are under a specific namespace to avoid pollution.
The issue is that we could only use var
not const
type OrderStatusType string
var OrderStatus = struct {
APPROVED OrderStatusType
APPROVAL_PENDING OrderStatusType
REJECTED OrderStatusType
REVISION_PENDING OrderStatusType
}{
APPROVED: "approved",
APPROVAL_PENDING: "approval pending",
REJECTED: "rejected",
REVISION_PENDING: "revision pending",
}
In your manifest file, try adding the following to the <activity>
that you want to show the keyboard when the activity starts:
android:windowSoftInputMode="stateVisible"
This should cause the keyboard to become visible when the activity starts.

(EDITED) I made it so it stops after 100 times
@echo off
goto actual
set /a loopcount=0
:actual
set /a loopcount=%loopcount% + 1
echo %random% %random% %random% %random%
timeout 1 /nobreak>nul
if %loopcount%== 100 goto stop
goto actual
:stop
exit
This will generate 4 random numbers ever 1 second 100 times. Take out the "timeout 1 /nobreak>nul" to make it go super fast.
RPC is another key difference. Thrift generates code to implement RPC clients and servers wheres Protocol Buffers seems mostly designed as a data-interchange format alone.

Some explain from C++Primer 5th Page 35
If we assign an out-of-range value to an object of unsigned type, the result is the remainder of the value modulo the number of values the target type can hold.
For example, an 8-bit unsigned char can hold values from 0 through 255, inclusive. If we assign a value outside the range, the compiler assigns the remainder of that value modulo 256.
unsigned char c = -1; // assuming 8-bit chars, c has value 255
If we assign an out-of-range value to an object of signed type, the result is undefined. The program might appear to work, it might crash, or it might produce garbage values.
Page 160: If any operand is an unsigned type, the type to which the operands are converted depends on the relative sizes of the integral types on the machine.
... When the signedness differs and the type of the unsigned operand is the same as or larger than that of the signed operand, the signed operand is converted to unsigned.
The remaining case is when the signed operand has a larger type than the unsigned operand. In this case, the result is machine dependent. If all values in the unsigned type fit in the large type, then the unsigned operand is converted to the signed type. If the values don't fit, then the signed operand is converted to the unsigned type.
For example, if the operands are long and unsigned int, and int and long have the same size, the length will be converted to unsigned int. If the long type has more bits, then the unsigned int will be converted to long.
I found reading this book is very helpful.
It seems to me to be a bug in PHP. The error
'Fatal error: Uncaught Error: Using $this when not in object context in'
appears in the function using $this
, but the error is that the calling function is using non-static function as a static. I.e:
Class_Name
{
function foo()
{
$this->do_something(); // The error appears there.
}
function do_something()
{
///
}
}
While the error is here:
Class_Name::foo();
If this is your detail.html
I don't see where do you load detail.js

Maybe this

As stated by others, your question is ambiguous at best. The problem is, you want to represent the object as a string, and then be able to construct the object again from that string.
However, note that while many object types in Java have string representations, this does not guarantee that an object can be constructed from its string representation.
To quote this source,
Object serialization is the process of saving an object's state to a sequence of bytes, as well as the process of rebuilding those bytes into a live object at some future time.
So, you see, what you want might not be possible. But it is possible to save your object's state to a byte sequence, and then reconstruct it from that byte sequence.
The bundle id (app ID) has a binding relationship with the apple id (apple id is the Apple development account, which also belongs to a certain development team). When the app is created, the bundle id (app ID) is already associated with you The development team is bound, so your app is being sent to other colleagues, he opens it in Xcode, and connects the real machine with a data cable to debug it will report the error as above;
To Solution
Follow the prompts to change the bundle id
Because some functions, such as third-party login, are bound to the bundle id to apply for the app key, etc., the bundle id cannot be modified. Then please find the apple id account registered by the bundle id before. Here, I will change It’s ok to become the apple id account I registered in the company group
If other colleagues in your group can run this app successfully on a real machine, it means that the "description file" corresponding to the apple id "certificate" used by him is correct.

Just change your password in the site. The old authentication will became outdated and Chrome will request it again.
Since I had a terminal open, I did a simple script to change the password and in two keypresses it were incremented.
To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
For Android Studio 3.0.0 and above:
allprojects {
repositories {
jcenter()
google()
}
}

It should be absolutely fixed the issue
This seems a little confused.
Opening your application in another window or tab will require your entire application to be re-bootstrapped, and then for your router to... pick up that url, convert it into a route, and load the appropriate component.
This is exactly what will happen if you just use a link instead. In fact, that's all that's happening.
The point of the router is to swap components in and out of your router-outlet, which is something that's been bootstrapped and exists within the confines of your running application and isn't shared across multiple windows.
You can solve this by using Data Transfer Objects (DTO's).
These are a bit like viewmodels where you put in the properties you need and you can map them manually in your controller or by using third-party solutions like AutoMapper.
With DTO's you can :

You should open command prompt, go to

"WHERE id = 1 ")
assert query.first().name == "Welcome to my blog"
I know this is an old question, but it is the top google result for "gitbash homedir windows" so figured I'd add my findings.

I tried setting HOME and HOMEDIR variables in windows.
I tried setting HOME and HOMEDIR variables in the git installation'setc/profile file.
I tried editing the "Start in" on the git-bash shortcut to be C:/user/myusername.
"env" command inside the git-bash shell would show correct c:/user/myusername. But git-bash would still start in U:
What ultimately fixed it for me was editing the git-bash shortcut and removing the "--cd-to-home" from the Target line.

On some servers and web hosts, it's possible to disable ModSecurity via .htaccess
, but be aware that you can only switch it on or off, you can't disable individual rules.
But a good practice that still keeps your site secure is to disable it only on specific URLs, rather than your entire site. You can specify which URLs to match via the regex in the <If>
statement below...
### DISABLE mod_security firewall
### Some rules are currently too strict and are blocking legitimate users
### We only disable it for URLs that contain the regex below
### The regex below should be placed between "m#" and "#"
### (this syntax is required when the string contains forward slashes)
<IfModule mod_security.c>
<If "%{REQUEST_URI} =~ m#/admin/#">
SecFilterEngine Off
SecFilterScanPOST Off
</If>
</IfModule>
For the Platform Independent Users or Windows users, what you can do is:
import runtime:
import (
"runtime"
"strings"
)
and then trim the string like this:
if runtime.GOOS == "windows" {
input = strings.TrimRight(input, "\r\n")
} else {
input = strings.TrimRight(input, "\n")
}
now you can compare it like that:
if strings.Compare(input, "a") == 0 {
//....yourCode
}
This is a better approach when you're making use of STDIN on multiple platforms.
This happens because on windows lines end with "\r\n"
which is known as CRLF, but on UNIX lines end with "\n"
which is known as LF and that's why we trim "\n"
on unix based operating systems while we trim "\r\n"
on windows.

How this works:
__get
, __set
, __call
and __callStatic
are invoked when the method or property is inaccessible. Your $bar
is public and therefor not inaccessible.
See the section on Property Overloading in the manual:
__set()
is run when writing data to inaccessible properties.__get()
is utilized for reading data from inaccessible properties.
The magic methods are not substitutes for getters and setters. They just allow you to handle method calls or property access that would otherwise result in an error. As such, there are much more related to error handling. Also note that they are considerably slower than using proper getter and setter or direct method calls.

It depends on how you format the Guid:
Guid.NewGuid().ToString()
=> 36 characters (Hyphenated)
outputs: 12345678-1234-1234-1234-123456789abc
Guid.NewGuid().ToString("D")
=> 36 characters (Hyphenated, same as ToString()
)
outputs: 12345678-1234-1234-1234-123456789abc
Guid.NewGuid().ToString("N")
=> 32 characters (Digits only)
outputs: 12345678123412341234123456789abc
Guid.NewGuid().ToString("B")
=> 38 characters (Braces)
outputs: {12345678-1234-1234-1234-123456789abc}
Guid.NewGuid().ToString("P")
=> 38 characters (Parentheses)
outputs: (12345678-1234-1234-1234-123456789abc)
Guid.NewGuid().ToString("X")
=> 68 characters (Hexadecimal)
outputs: {0x12345678,0x1234,0x1234,{0x12,0x34,0x12,0x34,0x56,0x78,0x9a,0xbc}}
I usually do this:
Const Q = """"
Dim a, g
a = "xyz"
g = "abcd " & Q & a & Q
If you need to wrap strings in quotes more often in your code and find the above approach noisy or unreadable, you can also wrap it in a function:
a = "xyz"
g = "abcd " & Q(a)
Function Q(s)
Q = """" & s & """"
End Function
For people in the future seeing this, postgres

You can probably bank on this being true for most...double check however!
First you have to create a migration, you can use the migrate:make command on the laravel artisan CLI.Old laravel version like laravel 4 you may use this command for Laravel 4:
php artisan migrate:make add_paid_to_users
And for laravel 5 version
for Laravel 5+:
php artisan make:migration add_paid_to_users_table --table=users
Then you need to use the Schema::table() . And you have to add the column:
public function up()
{
Schema::table('users', function($table) {
$table->integer('paid');
});
}
further you can check this
If you don't want to include the backslash, but only the text after it, try this: ([^\\]+)$
or for unix: ([^\/]+)$
Then you will be able to reference your files by using a path such as @".\my_html.html"
Copy to Output Directory will put the file in the same folder as your binary dlls when the project is built. This works with any content file, even if its in a sub folder.
If you use a sub folder, that too will be copied in to the bin folder so your path would then be @".\my_subfolder\my_html.html"
In order to create a URI you can use locally (instead of served via the web), you'll need to use the file protocol, using the base directory of your binary - note: this will only work if you set the Copy to Ouptut Directory as above or the path will not be correct.
This is what you need:
string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Url = new Uri(String.Format("file:///{0}/my_html.html", curDir));
You'll have to change the variables and names of course.
If you have not ejected from CRA yet, you can't easily modify your webpack config. The config file is hidden in node_modules/react_scripts/config/webpackDevServer.config.js
. You are discouraged to change that config.

to true
to disable the host check:
DANGEROUSLY_DISABLE_HOST_CHECK=true yarn start

Consider creating a function which can return a table and be used in a query.
https://msdn.microsoft.com/en-us/library/ms186755.aspx
The main difference between a function and a procedure is that a function makes no changes to any table. It only returns a value.
In this example I'm creating a query to give me the counts of all the columns in a given table which aren't null or empty.
There are probably many ways to clean this up. But it illustrates a function well.
USE Northwind
CREATE FUNCTION usp_listFields(@schema VARCHAR(50), @table VARCHAR(50))
RETURNS @query TABLE (
FieldName VARCHAR(255)
)
BEGIN
INSERT @query
SELECT
'SELECT ''' + @table+'~'+RTRIM(COLUMN_NAME)+'~''+CONVERT(VARCHAR, COUNT(*)) '+
'FROM '+@schema+'.'+@table+' '+
' WHERE isnull("'+RTRIM(COLUMN_NAME)+'",'''')<>'''' UNION'
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table and TABLE_SCHEMA = @schema
RETURN
END
Then executing the function with
SELECT * FROM usp_listFields('Employees')
produces a number of rows like:
SELECT 'Employees~EmployeeID~'+CONVERT(VARCHAR, COUNT(*)) FROM dbo.Employees WHERE isnull("EmployeeID",'')<>'' UNION
SELECT 'Employees~LastName~'+CONVERT(VARCHAR, COUNT(*)) FROM dbo.Employees WHERE isnull("LastName",'')<>'' UNION
SELECT 'Employees~FirstName~'+CONVERT(VARCHAR, COUNT(*)) FROM dbo.Employees WHERE isnull("FirstName",'')<>'' UNION

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.
This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html
(It also includes the drag/drop interface but that's easily ignored.)
Basically what it comes down to is this:
<input id="files" type="file" />
<script>
document.getElementById('files').addEventListener('change', function(e) {
var file = this.files[0];
var xhr = new XMLHttpRequest();
(xhr.upload || xhr).addEventListener('progress', function(e) {
var done = e.position || e.loaded
var total = e.totalSize || e.total;
console.log('xhr progress: ' + Math.round(done/total*100) + '%');
});
xhr.addEventListener('load', function(e) {
console.log('xhr upload complete', e, this.responseText);
});
xhr.open('post', '/URL-HERE', true);
xhr.send(file);
});
</script>
(demo: http://jsfiddle.net/rudiedirkx/jzxmro8r/)
So basically what it comes down to is this =)
xhr.send(file);
Where file
is typeof Blob
: http://www.w3.org/TR/FileAPI/
Another (better IMO) way is to use FormData
. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.
var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);
FormData
makes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).
All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.
This is how I handled the request (1 image per request) in PHP:
if ( isset($_FILES['file']) ) {
$filename = basename($_FILES['file']['name']);
$error = true;
// Only upload if on my home win dev machine
if ( isset($_SERVER['WINDIR']) ) {
$path = 'uploads/'.$filename;
$error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
}
$rsp = array(
'error' => $error, // Used in JS
'filename' => $filename,
'filepath' => '/tests/uploads/' . $filename, // Web accessible
);
echo json_encode($rsp);
exit;
}

I'm aware the question is php
oriented, but the best way to redirect a POST
request is probably using .htaccess
, ie:
RewriteEngine on
RewriteCond %{REQUEST_URI} string_to_match_in_url
RewriteCond %{REQUEST_METHOD} POST
RewriteRule ^(.*)$ https://domain.tld/$1 [L,R=307]
Explanation:
By default, if you want to redirect request with POST data, browser redirects it via GET with 302 redirect
. This also drops all the POST data associated with the request. Browser does this as a precaution to prevent any unintentional re-submitting of POST transaction.
But what if you want to redirect anyway POST request with it’s data? In HTTP 1.1, there is a status code for this. Status code 307
indicates that the request should be repeated with the same HTTP method and data. So your POST request will be repeated along with it’s data if you use this status code.
What it seems like to me is that by calling the keys method you're returning to python a dictionary object when it's looking for a list or a tuple. So try taking all of the keys in the dictionary, putting them into a list and then using the for loop.
The name
property is marked as protected
. This was added in TypeScript 1.3 and is now firmly established.
The makeSound
method is marked as abstract
, as is the class. You cannot directly instantiate an Animal
now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.
abstract class Animal {
constructor(protected name: string) { }
abstract makeSound(input : string) : string;
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name: string) { super(name); }
makeSound(input : string) : string {

move() {

super.move(5);
}

The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:
class Animal {
constructor(public name) { }
makeSound(input : string) : string {
throw new Error('This method is abstract');
}
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
(2017) SIMPLE ES6 composable arrow functions
I can't resist sharing this for those who may be writing some modern functional/compositional js using ES6. Here are some slick one-liners I am using in a color module that does color interpolation for data visualization.
Note that this does not handle the alpha channel at all.
const arrayToRGBString = rgb => `rgb(${rgb.join(',')})`;
const hexToRGBArray = hex => hex.match(/[A-Za-z0-9]{2}/g).map(v => parseInt(v, 16));
const rgbArrayToHex = rgb => `#${rgb.map(v => v.toString(16).padStart(2, '0')).join('')}`;
const rgbStringToArray = rgb => rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/).splice(1, 3)
.map(v => Number(v));
const rgbStringToHex = rgb => rgbArrayToHex(rgbStringToArray(rgb));
BTW, If you like this style/syntax, I wrote a full color module (modern-color) you can grab from npm. I made it so I could use prop getters for conversion and parse virtually anything (Color.parse(anything)). Worth a look if you deal with color a lot like I do.

In objective c you can use CGRectContainsPoint(yourview.frame, touchpoint)
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
UITouch* touch = [touches anyObject];
CGPoint touchpoint = [touch locationInView:self.view];
if( CGRectContainsPoint(yourview.frame, touchpoint) ) {
}else{
}}
In swift 3 yourview.frame.contains(touchpoint)
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let touch:UITouch = touches.first!
let touchpoint:CGPoint = touch.location(in: self.view)
if wheel.frame.contains(touchpoint) {
}else{
}
}
I also needed what you've been searching for and did some research.
I found JSC3D (https://code.google.com/p/jsc3d/). It's a project written entirely in Javascript and uses the HTML canvas. It has been tested for Opera, Chrome, Firefox, Safari, IE9 and more.
Then you have services as p3d.in and Sketchfab that give you a nice reader to view 3D models on a web page: they use HTML5 and WebGL. They both have a free version.
If you override a parent method in its child, child objects will always use the overridden version. But; you can use the keyword super
to call the parent method, inside the body of the child method.
public class PolyTest{
public static void main(String args[]){
new Child().foo();
}
}
class Parent{
public void foo(){
System.out.println("I'm the parent.");
}
}
class Child extends Parent{
@Override
public void foo(){
//super.foo();
System.out.println("I'm the child.");
}
}
This would print:
I'm the child.
Uncomment the commented line and it would print:
I'm the parent.
I'm the child.
You should look for the concept of Polymorphism.
I know the answer by @Pascal Thivent has solved the issue. I would like to add a bit more to his answer to others who might be surfing this thread.
If you are like me in the initial days of learning and wrapping your head around the concept of using the @OneToMany
annotation with the 'mappedBy
' property, it also means that the other side holding the @ManyToOne
annotation with the @JoinColumn
is the 'owner' of this bi-directional relationship.
Also, mappedBy
takes in the instance name (mCustomer
in this example) of the Class variable as an input and not the Class-Type (ex:Customer) or the entity name(Ex:customer).
BONUS :
Also, look into the orphanRemoval
property of @OneToMany
annotation. If it is set to true, then if a parent is deleted in a bi-directional relationship, Hibernate automatically deletes it's children.
As described in Cast Functions and Operators:
The type for the result can be one of the following values:
BINARY[(N)]
CHAR[(N)]
DATE
DATETIME
DECIMAL[(M[,D])]
SIGNED [INTEGER]
TIME
UNSIGNED [INTEGER]
Therefore, you should use:
SELECT CAST(PROD_CODE AS UNSIGNED) FROM PRODUCT
Try this:
REGEXP '^[a-z0-9]+$'
As regexp is not case sensitive except for binary fields.
According to the LanguageManual, you can use unix_timestamp()
to get the "current time stamp using the default time zone." If you need to convert that to something more human-readable, you can use from_unixtime(unix_timestamp())
.
Hope that helps.
SELECT username FROM all_users ORDER BY username;
response[0]
is not defined, check if it is defined and then check for its property title.
if(typeof response[0] !== 'undefined' && typeof response[0].title !== 'undefined'){
//Do something
}
You're probably just getting a stack overflow here. The array is too big to fit in your program's stack address space.
If you allocate the array on the heap you should be fine, assuming your machine has enough memory.
int* array = new int[1000000];
But remember that this will require you to delete[]
the array. A better solution would be to use std::vector<int>
and resize it to 1000000 elements.
rows = int(input('How many stars in each row do you want?'))
columns = int(input('How many columns do you want?'))
i = 0
for i in range(columns):
print ("*" * rows)
i = i + 1
Under Ubuntu or debian, you can view crontab by /var/spool/cron/crontabs/
and then a file for each user is in there. That's only for user-specific crontab's of course.
For Redhat 6/7 and Centos, the crontab is under /var/spool/cron/
.
The problem happened to me just in production just because I imported jquery with HTTP and not HTTPS (and production is HTTPS)
A very interesting project is disruptor. It has a ringbuffer and is used from what I know in financial applications.
See here: code of ringbuffer
I checked both Guava's EvictingQueue and ArrayDeque.
ArrayDeque does not limit growth if it's full it will double size and hence is not precisely acting like a ringbuffer.
EvictingQueue does what it promises but internally uses a Deque to store things and just bounds memory.
Hence, if you care about memory being bounded ArrayDeque is not fullfilling your promise. If you care about object count EvictingQueue uses internal composition (bigger object size).
A simple and memory efficient one can be stolen from jmonkeyengine. verbatim copy

Pandas
uses matplotlib
as a library for basic plots. The easiest way in your case will using the following:
import pandas as pd
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
df.plot(x='col_name_1', y='col_name_2', style='o')
However, I would recommend to use seaborn
as an alternative solution if you want have more customized plots while not going into the basic level of matplotlib.
In this case you the solution will be following:
import pandas as pd
import seaborn as sns
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df)
Something like this should do it for you.
Sub CombineColumns1()
Dim xRng As Range
Dim i As Long, j As Integer
Dim xNextRow As Long
Dim xTxt As String

xTxt = .RangeSelection.Address

If xRng Is Nothing Then Exit Sub
j = xRng.Columns(1).Column
For i = 4 To xRng.Columns.Count Step 3
'Need to recalculate the last row, as some of the final columns may not have data in all rows
xNextRow = .Cells(.Rows.Count, j).End(xlUp).Row + 1
.Range(xRng.Cells(1, i), xRng.Cells(xRng.Rows.Count, i + 2)).Copy .Cells(xNextRow, j)
.Range(xRng.Cells(1, i), xRng.Cells(xRng.Rows.Count, i + 2)).Clear
Next
End With
End Sub
You could do this too.
Sub TransposeFormulas()
Dim vFormulas As Variant
Dim oSel As Range
If TypeName(Selection) <> "Range" Then
MsgBox "Please select a range of cells first.", _
vbOKOnly + vbInformation, "Transpose formulas"
Exit Sub
End If
Set oSel = Selection
vFormulas = oSel.Formula
vFormulas = Application.WorksheetFunction.Transpose(vFormulas)
oSel.Offset(oSel.Rows.Count + 2).Resize(oSel.Columns.Count, oSel.Rows.Count).Formula = vFormulas
End Sub

I know this is a really old question but i think i have a solution In the newer versions of openCV fonts are repesented by a number like this
FONT_HERSHEY_SIMPLEX = 0,
FONT_HERSHEY_PLAIN = 1,
FONT_HERSHEY_DUPLEX = 2,
FONT_HERSHEY_COMPLEX = 3,
FONT_HERSHEY_TRIPLEX = 4,
FONT_HERSHEY_COMPLEX_SMALL = 5,
FONT_HERSHEY_SCRIPT_SIMPLEX = 6,
FONT_HERSHEY_SCRIPT_COMPLEX = 7,
FONT_ITALIC = 16
so all you have to do is replace the font name with the corresponding number
cv2.putText(image,"Hello World!!!", (x,y), 0, 2, 255)
again i know its an old question but it may help someone in the future
The best video playback/encoding library I have ever seen is ffmpeg. It plays everything you throw at it. (It is used by MPlayer.) It is written in C but I found some Java wrappers.
In-Short Differences are
1) PCL is not going to have Full Access to .NET Framework , where as SharedProject has.
2) #ifdef for platform specific code - you can not write in PCL (#ifdef option isn’t available to you in a PCL because it’s compiled separately, as its own DLL, so at compile time (when the #ifdef is evaluated) it doesn’t know what platform it will be part of. ) where as Shared project you can.
3) Platform specific code is achieved using Inversion Of Control in PCL , where as using #ifdef statements you can achieve the same in Shared Project.
An excellent article which illustrates differences between PCL vs Shared Project can be found at the following link
http://hotkrossbits.com/2015/05/03/xamarin-forms-pcl-vs-shared-project/
I assume you are using TCP sockets for the client-server interaction? One way to send different types of data to the server and have it be able to differentiate between the two is to dedicate the first byte (or more if you have more than 256 types of messages) as some kind of identifier. If the first byte is one, then it is message A, if its 2, then its message B. One easy way to send this over the socket is to use DataOutputStream/DataInputStream
:
Client:
Socket socket = ...; // Create and connect the socket
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());
// Send first message
dOut.writeByte(1);
dOut.writeUTF("This is the first type of message.");
dOut.flush(); // Send off the data
// Send the second message
dOut.writeByte(2);
dOut.writeUTF("This is the second type of message.");
dOut.flush(); // Send off the data
// Send the third message
dOut.writeByte(3);
dOut.writeUTF("This is the third type of message (Part 1).");
dOut.writeUTF("This is the third type of message (Part 2).");
dOut.flush(); // Send off the data
// Send the exit message
dOut.writeByte(-1);
dOut.flush();
dOut.close();
Server:
Socket socket = ... // Set up receive socket
DataInputStream dIn = new DataInputStream(socket.getInputStream());
boolean done = false;
while(!done) {
byte messageType = dIn.readByte();
switch(messageType)
{
case 1: // Type A
System.out.println("Message A: " + dIn.readUTF());
break;
case 2: // Type B
System.out.println("Message B: " + dIn.readUTF());
break;
case 3: // Type C
System.out.println("Message C [1]: " + dIn.readUTF());
System.out.println("Message C [2]: " + dIn.readUTF());
break;
default:
done = true;
}
}
dIn.close();
Obviously, you can send all kinds of data, not just bytes and strings (UTF).
Note that writeUTF
writes a modified UTF-8 format, preceded by a length indicator of an unsigned two byte encoded integer giving you 2^16 - 1 = 65535
bytes to send. This makes it possible for readUTF
to find the end of the encoded string. If you decide on your own record structure then you should make sure that the end and type of the record is either known or detectable.
The problem is that t.join() blocks the click event, the main thread does not get back to the event loop to process repaints. See Why ttk Progressbar appears after process in Tkinter or TTK progress bar blocked when sending email
LENGTH()
does return the string length (just verified). I suppose that your data is padded with blanks - try
SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;
instead.
As OraNob
mentioned, another cause could be that CHAR
is used in which case LENGTH()
would also return the column width, not the string length. However, the TRIM()
approach also works in this case.

Your setters are strange, which is why you may be seeing a problem.
First, consider whether you even need these setters - if so, they should take a List<string>
, not just a string
:
set
{
_subHead = value;
}
These lines:
newSec.subHead.Add("test string");
Are calling the getter and then call Add
on the returned List<string>
- the setter is not invoked.
I know this answer is kinda old and there are some very good answers who already solve the problem. In order to expand the issue I'd like to mention one more thing that has driven me crazy for the last 4 or 5 hours.
It is VERY VERY VERY important that your properties in your model class have the set attribute enabled.
This WILL NOT work (parameter still null):
/* Action code */
[HttpPost]
public Weird NOURLAuthenticate([FromBody] Weird form) {
return form;
}
/* Model class code */
public class Weird {
public string UserId {get;}
public string UserPwd {get;}
}
This WILL work:
/* Action code */
[HttpPost]
public Weird NOURLAuthenticate([FromBody] Weird form) {
return form;
}
/* Model class code */
public class Weird {
public string UserId {get; set;}
public string UserPwd {get; set;}
}
I have also got stuck into this and believe me disabling SELinux is not a good idea.
Please just use below and you are good,
sudo restorecon -R /var/www/mysite

Use Json
class instead of Content
as shown following:
// When I want to return an error:
if (!isFileSupported)
{
Response.StatusCode = (int) HttpStatusCode.BadRequest;
return Json("The attached file is not supported", MediaTypeNames.Text.Plain);
}
else
{
// When I want to return sucess:
Response.StatusCode = (int)HttpStatusCode.OK;
return Json("Message sent!", MediaTypeNames.Text.Plain);
}
Also set contentType:
contentType: 'application/json; charset=utf-8',
mysqli_select_db()
should have 2 parameters, the connection link and the database name -
mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));
Using mysqli_error
in the die statement will tell you exactly what is wrong as opposed to a generic error message.
$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
ADD COLUMN `ping_status` INT(1) NOT NULL
AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";
I believe you need to have ADD COLUMN
and use AFTER
, not BEFORE
.
In case you want to place column at the beginning of a table, use the FIRST
statement:
$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
ADD COLUMN `ping_status` INT(1) NOT NULL
FIRST";
error in the very first line public class StaticDemo {
Any Class A
which has access modifier as public
must have a separate source file as A.java
or A.jav
. This is specified in JLS 7.6 section:
If and only if packages are stored in a file system (§7.2), the host system may choose to enforce the restriction that it is a compile-time error if a type is not found in a file under a name composed of the type name plus an extension (such as .java or .jav) if either of the following is true:
The type is referred to by code in other compilation units of the package in which the type is declared.
The type is declared public (and therefore is potentially accessible from code in other packages).
However, you may have to remove public
access modifier from the Class declaration StaticDemo
. Then as StaticDemo
class will have no modifier it will become package-private, That is, it will be visible only within its own package.
Check out Controlling Access to Members of a Class
Try this:
function welcomeMessage() { var shape1 = new Shape(); //alert(shape1.draw()); alert(shape1.hasOwnProperty("name")); }
When working with reflection in JavaScript, member objects are always refered to as the name as a string. For example:
for(i in obj) { ... }
The loop iterator i will be hold a string value with the name of the property. To use that in code you have to address the property using the array operator like this:
for(i in obj) { alert("The value of obj." + i + " = " + obj[i]); }
Here you get JSONObject so change this line:
JSONArray jsonArray = new JSONArray(readlocationFeed);
with following:
JSONObject jsnobject = new JSONObject(readlocationFeed);
and after
JSONArray jsonArray = jsnobject.getJSONArray("locations");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject explrObject = jsonArray.getJSONObject(i);
}

In addition to user701648's answer, you can store your credentials in your home folder (global for all projects), instead of project folder using the following command
$ git config --global credential.helper store

The directory you're switching to is on another drive, you need to switch to that drive using :

D:\Docs\Java>
You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start()
. The headers will be sent automatically when any HTML is output.
Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.
Move the session_start()
to the top of your document :
<?php session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php'; // more PHP code here.
Or you can use the ANDROID_ID setting from Android.Provider.Settings.System (as described here strazerre.com).
This has the advantage that it doesn't require special permissions but can change if another application has write access and changes it (which is apparently unusual but not impossible).
Just for reference here is the code from the blog:
import android.provider.Settings;
import android.provider.Settings.System;
String androidID = System.getString(this.getContentResolver(),Secure.ANDROID_ID);
Implementation note: if the ID is critical to the system architecture you need to be aware that in practice some of the very low end Android phones & tablets have been found reusing the same ANDROID_ID (9774d56d682e549c was the value showing up in our logs)
I've used Sothink SWF decompiler a couple of times, the only problem is that as project gets more complex, the output of decompiler gets harder to compile back again. But it ensures that you can get your .as files most of the time, compilable fla is a question.
Make the list a character vector (not a vector of names)
rm(list = c('temp1','temp2'))
or
rm(temp1, temp2)
might fail working with link_directories, then add each static library like following:
target_link_libraries(foo /path_to_static_library/libbar.a)
The "0x" counts towards the eight character count. You need "%#010x"
.
Note that #
does not append the 0x to 0 - the result will be 0000000000
- so you probably actually should just use "0x%08x"
anyway.
Following are some things I found in my collection of obscure Ruby.
So, in Ruby, a simple no-bells implementation of the Unix command cat
would be:
#!/usr/bin/env ruby
puts ARGF.read
ARGF
is your friend when it comes to input; it is a virtual file that gets all input from named files or all from STDIN.
ARGF.each_with_index do |line, idx|
print ARGF.filename, ":", idx, ";", line
end
# print all the lines in every file passed via command line that contains login
ARGF.each do |line|
puts line if line =~ /login/
end
Thank goodness we didn’t get the diamond operator in Ruby, but we did get ARGF
as a replacement. Though obscure, it actually turns out to be useful. Consider this program, which prepends copyright headers in-place (thanks to another Perlism, -i
) to every file mentioned on the command-line:
#!/usr/bin/env ruby -i
Header = DATA.read
ARGF.each_line do |e|
puts Header if ARGF.pos - e.length == 0
puts e
end

There is not official api support which means that it is not documented for the public and the libraries may change at any time. I realize you don't want to leave the application but here's how you do it with an intent for anyone else wondering.
public void sendData(int num){
String fileString = "..."; //put the location of the file here
Intent mmsIntent = new Intent(Intent.ACTION_SEND);
mmsIntent.putExtra("sms_body", "text");
mmsIntent.putExtra("address", num);
mmsIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(fileString)));
mmsIntent.setType("image/jpeg");
startActivity(Intent.createChooser(mmsIntent, "Send"));
}
I haven't completely figured out how to do things like track the delivery of the message but this should get it sent.
You can be alerted to the receipt of mms the same way as sms. The intent filter on the receiver should look like this.
<intent-filter>
<action android:name="android.provider.Telephony.WAP_PUSH_RECEIVED" />
<data android:mimeType="application/vnd.wap.mms-message" />
</intent-filter>
Put your code in a method.
Try this:
public class MyClass {
public static void main(String[] args) {
UserInput input = new UserInput();
input.name();
}
}
Then "run" the class from your IDE
Currently you can use what docker offers now for a general and more complete cleaning:
docker system prune
To additionally remove any stopped containers and all unused images (not just dangling images), add the -a
flag to the command:
docker system prune -a
When it comes to memory usage, x86 is limited to circa 3 / 3,5 Gb, while x64 works fine with 4 Gb and more.
Moreover, when it comes to Windows, x86 will run on both X86 and x64 processors, while x64 requires x64 processor only.
It's possible to have a property of type List<T>
but your class needs to be passed the T
too.
public class ClassName<T>
{
public List<T> MyProperty { get; set; }
}
You should not attempt to parse HTML with regex. HTML is not a regular language, so any regex you come up with will likely fail on some esoteric edge case. Please refer to the seminal answer to this question for specifics. While mostly formatted as a joke, it makes a very good point.
The following examples are Java, but the regex will be similar -- if not identical -- for other languages.
String target = someString.replaceAll("<[^>]*>", "");
Assuming your non-html does not contain any < or > and that your input string is correctly structured.
If you know they're a specific tag -- for example you know the text contains only <td>
tags, you could do something like this:
String target = someString.replaceAll("(?i)<td[^>]*>", "");
Edit: Omega brought up a good point in a comment on another post that this would result in multiple results all being squished together if there were multiple tags.
For example, if the input string were <td>Something</td><td>Another Thing</td>
, then the above would result in SomethingAnother Thing
.
In a situation where multiple tags are expected, we could do something like:
String target = someString.replaceAll("(?i)<td[^>]*>", " ").replaceAll("\\s+", " ").trim();
This replaces the HTML with a single space, then collapses whitespace, and then trims any on the ends.
AFAIK you can't do that.
What I did at my place of work, is transfer the files to your home
(~
) folder (or really any folder that you have full permissions in, i.e chmod 777
or variants) via WinSCP, and then SSH to to your linux machine and sudo
from there to your destination folder.
Another solution would be to change permissions of the directories you are planning on uploading the files to, so your user (which is without sudo
privileges) could write to those dirs.
I would also read about WinSCP Remote Commands for further detail.
The res
argument in the http.get()
callback is not the body, but rather an http.ClientResponse object. You need to assemble the body:
var url = 'http://graph.facebook.com/517267866/?fields=picture';
http.get(url, function(res){
var body = '';
res.on('data', function(chunk){
body += chunk;
});
res.on('end', function(){
var fbResponse = JSON.parse(body);
console.log("Got a response: ", fbResponse.picture);
});
}).on('error', function(e){
console.log("Got an error: ", e);
});

What about trying with VLOOKUP
? The syntax is:
=VLOOKUP(cell you want to copy, range you want to copy, 1, FALSE).
It should do the trick.
I faced the same issue, and I found out the problem was the location of my images.
Instead of saving them into the src
folder, you should store them in the public
directory and have direct access.
Kudos.
Below is example you can use:
create temp table test2 (
id1 numeric,
id2 numeric,
id3 numeric,
id4 numeric,
id5 numeric,
id6 numeric,
id7 numeric,
id8 numeric,
id9 numeric,
id10 numeric)
with (oids = false);
do
$do$
declare
i int;
begin
for i in 1..100000
loop
insert into test2 values (random(), i * random(), i / random(), i + random(), i * random(), i / random(), i + random(), i * random(), i / random(), i + random());
end loop;
end;
$do$;
In client application (application is not web application, e.g may be swing app)
private static ApplicationContext context = new ClassPathXmlApplicationContext("test-client.xml");
context.getBean(name);
No need of web.xml. ApplicationContext as container for getting bean service. No need for web server container. In test-client.xml there can be Simple bean with no remoting, bean with remoting.
Conclusion: In Scenario 1 applicationContext and DispatcherServlet
are not related.
In a server application (application deployed in server e.g Tomcat). Accessed service via remoting from client program (e.g Swing app)
Define listener in web.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
At server startup ContextLoaderListener
instantiates beans defined in applicationContext.xml.
Assuming you have defined the following in applicationContext.xml:
<import resource="test1.xml" />
<import resource="test2.xml" />
<import resource="test3.xml" />
<import resource="test4.xml" />
The beans are instantiated from all four configuration files test1.xml, test2.xml, test3.xml, test4.xml.
Conclusion: In Scenario 2 applicationContext and DispatcherServlet
are not related.
In a web application with spring MVC.
In web.xml define:
<servlet>
<servlet-name>springweb</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springweb</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
When Tomcat starts, beans defined in springweb-servlet.xml are instantiated.
DispatcherServlet
extends FrameworkServlet
. In FrameworkServlet
bean instantiation takes place for springweb . In our case springweb is FrameworkServlet.
Conclusion: In Scenario 3 applicationContext and DispatcherServlet
are not related.
In web application with spring MVC. springweb-servlet.xml for servlet and applicationContext.xml for accessing the business service within the server program or for accessing DB service in another server program.
In web.xml the following are defined:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springweb</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springweb</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
At server startup, ContextLoaderListener
instantiates beans defined in applicationContext.xml; assuming you have declared herein:
<import resource="test1.xml" />
<import resource="test2.xml" />
<import resource="test3.xml" />
<import resource="test4.xml" />
The beans are all instantiated from all four test1.xml, test2.xml, test3.xml, test4.xml. After the completion of bean instantiation defined in applicationContext.xml, beans defined in springweb-servlet.xml are instantiated.
So the instantiation order is: the root (application context), then FrameworkServlet.
Now it should be clear why they are important in which scenario.
After try few different ways, i found that if you don't want to use:
let audience = Audience.Public.toRaw()
You can still archive it using a struct
struct Audience {
static let Public = "Public"
static let Friends = "Friends"
static let Private = "Private"
}
then your code:
let audience = Audience.Public
will work as expected. It isn't pretty and there are some downsides because you not using a "enum", you can't use the shortcut only adding .Private neither will work with switch cases.
Included with git — Run git gui
from the command line, and the Windows msysgit installer adds it to the Start menu.
Git GUI can do a majority of what you'd need to do with git. Including stage changes, configure git and repositories, push changes, create/checkout/delete branches, merge, and many other things.
One of my favourite features is the "stage line" and "stage hunk" shortcuts in the right-click menu, which lets you commit specific parts of a file. You can achieve the same via git add -i
, but I find it easier to use.
It isn't the prettiest application, but it works on almost all platforms (being based upon Tcl/Tk)
Also included with git. It is a git history viewer, and lets you visualise a repository's history (including branches, when they are created, and merged). You can view and search commits.
Goes together nicely with git-gui.
Mac OS X application. Mainly an equivalent of git log
, but has some integration with github (like the "Network view").
Looks pretty, and fits with Mac OS X. You can search repositories. The biggest critisism of Gitnub is that it shows history in a linear fashion (a single branch at a time) - it doesn't visualise branching and merging, which can be important with git, although this is a planned improvement.

Intends to be a "gitk clone for OS X".
It can visualise non-linear branching history, perform commits, view and search commits, and it has some other nice features like being able to "Quicklook" any file in any revision (press space in the file-list view), export any file (via drag and drop).
It is far better integrated into OS X than git-gui
/gitk
, and is fast and stable even with exceptionally large repositories.
The original git repository pieter has not updated recently (over a year at time of writing). A more actively maintained branch is available at brotherbard/gitx - it adds "sidebar, fetch, pull, push, add remote, merge, cherry-pick, rebase, clone, clone to"

gitg is a git repository viewer targeting gtk+/GNOME. One of its main objectives is to provide a more unified user experience for git frontends across multiple desktops. It does this not be writing a cross-platform application, but by close collaboration with similar clients for other operating systems (like GitX for OS X).
Gitbox is a Mac OS X graphical interface for Git version control system. In a single window you see branches, history and working directory status.
Everyday operations are easy: stage and unstage changes with a checkbox. Commit, pull, merge and push with a single click. Double-click a change to show a diff with FileMerge.app.
The Gity website doesn't have much information, but from the screenshots on there it appears to be a feature rich open source OS X git gui.
Meld is a visual diff and merge tool. You can compare two or three files and edit them in place (diffs update dynamically). You can compare two or three folders and launch file comparisons. You can browse and view a working copy from popular version control systems such such as CVS, Subversion, Bazaar-ng and Mercurial [and Git].
A Git GUIfor OSX by Steve Dekorte.
At a glance, see which remote branches have changes to pull and local repos have changes to push. The git ops of add, commit, push, pull, tag and reset are supported as well as visual diffs and visual browsing of project hieracy that highlights local changes and additions.

EGit is an Eclipse Team provider for the Git version control system. Git is a distributed SCM, which means every developer has a full copy of all history of every revision of the code, making queries against the history very fast and versatile.
The EGit project is implementing Eclipse tooling on top of the JGit Java implementation of Git.
Open Source for Windows - installs everything you need to work with Git in a single package, easy to use.
Git Extensions is a toolkit to make working with Git on Windows more intuitive. The shell extension will intergrate in Windows Explorer and presents a context menu on files and directories. There is also a Visual Studio plugin to use git from Visual Studio.
Big thanks to dbr for elaborating on the git gui stuff.
SourceTree is a free Mac client for Git, Mercurial and SVN. Built by Atlassian, the folks behind BitBucket, it seems to work equally well with any VC system, which allows you to master a single tool for use with all of your projects, however they're version-controlled. Feature-packed, and FREE.
Expert-Ready & Feature-packed for both novice and advanced users:
Review outgoing and incoming changesets. Cherry-pick between branches. Patch handling, rebase, stash / shelve and much more.
I have been looking for this for a few hours, this was the first article i came accross and although it has the best answer, the most popular answers i think are off the mark. Certainly for what i needed. weichsel's and shakazed's answers were right on the button but a bit obscured in the articles. To put you right to the project. Here: Just create a new Android project based on existing sample. Choose ApiDemos:
Look under the source folder
ApiDemos/src/com/example/android/apis/graphics/spritetext
And you will find everything you need.
As per Google recaptcha documentation
localhost domains are no longer supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key
It's the null conditional operator. It basically means:
"Evaluate the first operand; if that's null, stop, with a result of null. Otherwise, evaluate the second operand (as a member access of the first operand)."
In your example, the point is that if a
is null
, then a?.PropertyOfA
will evaluate to null
rather than throwing an exception - it will then compare that null
reference with foo
(using string's ==
overload), find they're not equal and execution will go into the body of the if
statement.
In other words, it's like this:
string bar = (a == null ? null : a.PropertyOfA);
if (bar != foo)
{
...
}
... except that a
is only evaluated once.
Note that this can change the type of the expression, too. For example, consider FileInfo.Length
. That's a property of type long
, but if you use it with the null conditional operator, you end up with an expression of type long?
:
FileInfo fi = ...; // fi could be null
long? length = fi?.Length; // If fi is null, length will be null
Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.
HTML:
<h1>Hello world!</h1>
Javascript (jQuery):
$(document).ready(function(){
$('h1').css({ 'width':'100%', 'text-align':'center' });
var h1 = $('h1').height();
var h = h1/2;
var w1 = $(window).height();
var w = w1/2;
var m = w - h
$('h1').css("margin-top",m + "px")
});
This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top
of the h1. The beauty of this method is that it works on multiple-line h1
s.
EDIT: I modified it so that it centered it every time the window is resized.
