In additon to other answers - very often, you do not have to iterate using the index but you can simply use a for-each expression:
my_list = ['a', 'b', 'c']
for item in my_list:
print item
See my answer to a similar question here.
It sounds like you want a background-image to keep it's own aspect ratio while expanding to 100% width and getting cropped off on the top and bottom. If that's the case, do something like this:
.chapter {
position: relative;
height: 1200px;
z-index: 1;
}
#chapter1 {
background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
background-repeat: no-repeat;
background-size: 100% auto;
background-position: center top;
background-attachment: fixed;
}
jsfiddle: http://jsfiddle.net/ndKWN/3/
The problem with this approach is that you have the container elements at a fixed height, so there can be space below if the screen is small enough.
If you want the height to keep the image's aspect ratio, you'll have to do something like what I wrote in an edit to the answer I linked to above. Set the container's height
to 0 and set the padding-bottom
to the percentage of the width:
.chapter {
position: relative;
height: 0;
padding-bottom: 75%;
z-index: 1;
}
#chapter1 {
background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
background-repeat: no-repeat;
background-size: 100% auto;
background-position: center top;
background-attachment: fixed;
}
jsfiddle: http://jsfiddle.net/ndKWN/4/
You could also put the padding-bottom
percentage into each #chapter
style if each image has a different aspect ratio. In order to use different aspect ratios, divide the height of the original image by it's own width, and multiply by 100 to get the percentage value.
If your vectors are sorted*, check out set_union from <algorithm>.
set_union(A.begin(), A.end(), B.begin(), B.end(), AB.begin());

I wrote a program with wpf
and used Database for showing images and this is my code:
SqlConnection con = new SqlConnection(@"Data Source=HITMAN-PC\MYSQL;
Initial Catalog=Payam;
Integrated Security=True");
SqlDataAdapter da = new SqlDataAdapter("select * from news", con);
DataTable dt = new DataTable();
da.Fill(dt);
string adress = dt.Rows[i]["ImgLink"].ToString();
ImageSource imgsr = new BitmapImage(new Uri(adress));
PnlImg.Source = imgsr;
You're going to have to rely on each individual's machine having the correct file associations. If you try and open the application from JavaScript/VBScript in a web page, the spawned application is either going to itself be sandboxed (meaning decreased permissions) or there are going to be lots of security prompts.
My suggestion is to look to SharePoint server for this one. This is something that we know they do and you can edit in place, but the question becomes how they manage to pull that off. My guess is direct integration with Office. Either way, this isn't something that the Internet is designed to do, because I'm assuming you want them to edit the original document and not simply create their own copy (which is what the default behavior of file://
would be.
So depending on you options, it might be possible to create a client side application that gets installed on all your client machines and then responds to a particular file handler that says go open this application on the file server. Then it wouldn't really matter who was doing it since all browsers would simply hand off the request to you. You would have to create your own handler like fileserver://
.
A View whose background color you can specify would do (height=a few dpi). Looked in real code and here it is:
<LinearLayout
android:id="@+id/lineA"
android:layout_width="fill_parent"
android:layout_height="2dp"
android:background="#000000" />
Note that it may be any kind of View
.
I guess the best way to do this is like this :

If you want to know the row and column of a value in a matrix
or data.frame
, consider using the arr.ind=TRUE
argument to which
:

row col
7 7 3
So 1578 is in column 3 (which you already know) and row 7.
I use @see to annotate methods of an interface implementation class where the description of the method is already provided in the javadoc of the interface.

You could create a new List
and addAll()

If your goal is to remove all elements from the list, you can iterate over each item, and then call:

It is a conflict (bug) between Themes inside style.xml file in android versions 7 (Api levels 24,25) & 8 (api levels 26,27), when you have
android:screenOrientation="portrait"
:inside specific activity (that crashes) in AndroidManifest.xml
&
<item name="android:windowIsTranslucent">true</item>
in the theme that applied to that activity inside style.xml
It can be solve by these ways according to your need :
1- Remove on of the above mentioned properties that make conflict
2- Change Activity orientation to one of these values as you need : unspecified
or behind
and so on that can be found here : Google reference for android:screenOrientation
`
3- Set the orientation programmatically in run time

Both are supported. To quote the Arduino homepage,
The core libraries are written in C and C++ and compiled using avr-gcc
Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.
If you don't have a problem integrating a small batch application, there is this program called Cmdow.exe that will allow you to hide console windows based on console title.
Console.Title = "MyConsole";
System.Diagnostics.Process HideConsole = new System.Diagnostics.Process();
HideConsole.StartInfo.UseShellExecute = false;
HideConsole.StartInfo.Arguments = "MyConsole /hid";
HideConsole.StartInfo.FileName = "cmdow.exe";
HideConsole.Start();
Add the exe to the solution, set the build action to "Content", set Copy to Output Directory to what suits you, and cmdow will hide the console window when it is ran.
To make the console visible again, you just change the Arguments
HideConsole.StartInfo.Arguments = "MyConsole /Vis";
I had exactly the same problem lately, and I installed Wireshark (it is a network monitoring tool). You can see everything with this, except encrypted traffic (HTTPS).

How about .toDateString()
?
Alternatively, use .getDate()
, .getMonth()
, and .getYear()
?
In my mind, if you want to group things by date, you simply want to access the date, not set it. Through having some set way of accessing the date field, you can compare them and group them together, no?
Check out all the fun Date methods here: MDN Docs
Edit: If you want to keep it as a date object, just do this:
var newDate = new Date(oldDate.toDateString());
Date's constructor is pretty smart about parsing Strings (though not without a ton of caveats, but this should work pretty consistently), so taking the old Date and printing it to just the date without any time will result in the same effect you had in the original post.

In Kotlin I have created an extension function for the Context. It takes a @StringRes and optionally you can provide parameters as well.
fun Context.fromHtmlWithParams(@StringRes stringRes: Int, parameter : String? = null) : Spanned {
val stringText = if (parameter.isNullOrEmpty()) {
this.getString(stringRes)
} else {
this.getString(stringRes, parameter)
}
return Html.fromHtml(stringText, Html.FROM_HTML_MODE_LEGACY)
}
Usage
tv_directors.text = context?.fromHtmlWithParams(R.string.directors, movie.Director)
I solved this (partially) by adding some lines of code to the bootstrap css library. You will have to modify tooltip.js, tooltip.less, popover.js, and popover.less
in tooltip.js, add this case in the switch statement there
case 'bottom-right':
tp = {top: pos.top + pos.height, left: pos.left + pos.width}
break
in tooltip.less, add these two lines in .tooltip{}
&.bottom-right { margin-top: -2px; }
&.bottom-right .tooltip-arrow { #popoverArrow > .bottom(); }
do the same in popover.js and popover.less. Basically, wherever you find code where other positions are mentioned, add your desired position accordingly.
As I mentioned earlier, this solved the problem partially. My problem now is that the little arrow of the popover does not appear.
note: if you want to have the popover in top-left, use top attribute of '.top' and left attribute of '.left'
Transactions are intended to run completely or not at all. The only way to complete a transaction is to commit, any other way will result in a rollback.
Therefore, if you begin and then not commit, it will be rolled back on connection close (as the transaction was broken off without marking as complete).
Since localStorage is a global object, you can add a watch in the dev tools. Just enter the dev tools, goto "watch", click on "Click to add..." and type in "localStorage".
colnames(trSamp)[2] <- "newname2"
attempts to set the second column's name. Your object only has one column, so the command throws an error. This should be sufficient:
colnames(trSamp) <- "newname2"

In python 2.7 you can use NumPy's numpy.std()

In Java, you can invoke that method using reflection provided that security manager allows it.
I just had a look at the source - Protractor is waiting for Angular only in a few cases (like when element.all
is invoked, or setting / getting location).
So Protractor won't wait for Angular to stabilise after every command.
Also, it looks like sometimes in my tests I had a race between Angular digest cycle and click event, so sometimes I have to do:
elm.click();
browser.driver.sleep(1000);
browser.waitForAngular();
using sleep to wait for execution to enter AngularJS context (triggered by click
event).

It uses the equals method on the objects. So unless Thing overrides equals and uses the variables stored in the objects for comparison, it will not return true on the contains()
method.
The syntax to disable an HTML input is as follows:

Another way to send header information to JavaScript would be through cookies. The server can extract whatever data it needs from the request headers and send them back inside a Set-Cookie
response header — and cookies can be read in JavaScript. As keparo says, though, it's best to do this for just one or two headers, rather than for all of them.

Running source
from a cronfile won't work as cron uses /bin/sh
as its default shell, which doesn't support source
. You need to set the SHELL environment variable to be /bin/bash
:
SHELL=/bin/bash
*/10 * * * * root source /path/to/virtualenv/bin/activate && /path/to/build/manage.py some_command > /dev/null
It's tricky to spot why this fails as /var/log/syslog
doesn't log the error details. Best to alias yourself to root so you get emailed with any cron errors. Simply add yourself to /etc/aliases
and run sendmail -bi
.

This is what you should do. It should work in that you have a 1 second animation, then a 4 second delay between iterations:
@keyframes barshine {
0% {
background-image:linear-gradient(120deg,rgba(255,255,255,0) 0%,rgba(255,255,255,0.25) -5%,rgba(255,255,255,0) 0%);
}
20% {
background-image:linear-gradient(120deg,rgba(255,255,255,0) 10%,rgba(255,255,255,0.25) 105%,rgba(255,255,255,0) 110%);
}
}
.progbar {
animation: barshine 5s 0s linear infinite;
}
So I've been messing around with this a lot and you can do it without being very hacky. This is the simplest way to put in a delay between animation iterations that's 1. SUPER EASY and 2. just takes a little logic. Check out this dance animation I've made:
.dance{
animation-name: dance;
-webkit-animation-name: dance;
animation-iteration-count: infinite;
-webkit-animation-iteration-count: infinite;

-ms-transform: rotate(20deg);
transform: rotate(20deg);
}
}
I actually came here trying to figure out how to put a delay in the animation, when I realized that you just 1. extend the duration of the animation and shirt the proportion of time for each animation. Beore I had them each lasting .5 seconds for the total duration of 2.5 seconds. Now lets say i wanted to add a delay equal to the total duration, so a 2.5 second delay.
You animation time is 2.5 seconds and delay is 2.5, so you change duration to 5 seconds. However, because you doubled the total duration, you'll want to halve the animations proportion. Check the final below. This worked perfectly for me.
@-webkit-keyframes dance {
0% {
-webkit-transform: rotate(0deg);
-moz-transform: rotate(0deg);
-o-transform: rotate(0deg);
-ms-transform: rotate(0deg);
transform: rotate(0deg);
}
10% {
-webkit-transform: rotate(20deg);

}
20% {
-webkit-transform: rotate(-120deg);
-moz-transform: rotate(-120deg);
-o-transform: rotate(-120deg);
-ms-transform: rotate(-120deg);
transform: rotate(-120deg);
}
30% {
-webkit-transform: rotate(0deg);
-moz-transform: rotate(0deg);
-o-transform: rotate(0deg);
-ms-transform: rotate(0deg);
transform: rotate(0deg);
}
40% {
-webkit-transform: rotate(-120deg);
-moz-transform: rotate(-120deg);

-moz-transform: rotate(0deg);
-o-transform: rotate(0deg);
-ms-transform: rotate(0deg);
transform: rotate(0deg);
}
}
In sum:
These are the calcultions you'd probably use to figure out how to change you animation's duration and the % of each part.
desired_duration = x
desired_duration = animation_part_duration1 + animation_part_duration2 + ... (and so on)
desired_delay = y
total duration = x + y
animation_part_duration1_actual = animation_part_duration1 * desired_duration / total_duration

You could use the INDIRECT function. This takes a string and converts it into a range
More info here
=INDIRECT("K"&A2)
But it's preferable to use INDEX as it is less volatile.
=INDEX(K:K,A2)
This returns a value or the reference to a value from within a table or range

I would like to add to the answers of BalusC and Pascal Thivent another common use of insertable=false, updatable=false
:
Consider a column that is not an id but some kind of sequence number. The responsibility for calculating the sequence number may not necessarily belong to the application.
For example, sequence number starts with 1000 and should increment by one for each new entity. This is easily done, and very appropriately so, in the database, and in such cases these configurations makes sense.
for Earth plugin APIs, create the balloon outside your loop and pass your counter to the function to get unique contents for each placemark!

Image workaround with transparent pixels on the right to serve as right margin.
The image workaround for the same is to create a PNG or GIF image (image file formats that support transparency) which has a transparent portion on the right of the image exactly equal to the number of pixels that you want to give a right margin of (eg: 5px, 10px, etc.)
This works well consistently across fixed widths as well as widths in percentages. Practically a good solution for accordion headers having a plus/minus or up/down arrow image on the header's right!
Downside: Unfortunately, you cannot use JPG unless the background portion of the container and the background color of the CSS background image are of the same flat color (with out a gradient/vignette), mostly white/black etc.
USE [ECMIS]
GO
EXEC dbo.sp_changedbowner @loginame = N'sa', @map = false
GO
It works.
Check all the references carefully
For me cleaning entire solution by deleting manually, updating (removing and adding) references again with version in sync with target machine and then building with with Copy Local > False for GAC assemblies solves the problem.
Once I faced the same issue. I was trying to take svn checkout using repository URL consisting of DOMAIN NAME. I tried to connect using IP address in place of DOMAIN NAME and I was able to take checkout
May be this time stamp fit you better Code
Function LastInputTimeStamp() As Date
LastInputTimeStamp = Now()
End Function
and each time you input data in defined cell (in my example below it is cell C36) you'll get a new constant time stamp. As an example in Excel file may use this
=IF(C36>0,LastInputTimeStamp(),"")
typeof myObj.prop2 === 'function';
will let you know if the function is defined.
if(typeof myObj.prop2 === 'function') {
alert("It's a function");
} else if (typeof myObj.prop2 === 'undefined') {
alert("It's undefined");
} else {
alert("It's neither undefined nor a function. It's a " + typeof myObj.prop2);
}
\0
is zero character. In C
it is mostly used to indicate the termination of a character string. Of course it is a regular character and may be used as such but this is rarely the case.
The simpler versions of the built-in string manipulation functions in C
require that your string is null-terminated(or ends with \0
).
After some searching and piecing together a couple of different solutions along with my own stuff, I came up with this function:
function parse_place(place)
{
var location = [];
for (var ac = 0; ac < place.address_components.length; ac++)
{
var component = place.address_components[ac];
switch(component.types[0])
{
case 'locality':
location['city'] = component.long_name;
break;
case 'administrative_area_level_1':
location['state'] = component.long_name;
break;
case 'country':
location['country'] = component.long_name;
break;
}
};
return location;
}
To configure Sublime to always use tabs try the adding the following to preferences->settings-user:
{
"tab_size": 4,
"translate_tabs_to_spaces": false
}
More information here: http://www.sublimetext.com/docs/2/indentation.html
you can use regex as the delimiter:
pd.read_csv("whitespace.csv", header=None, delimiter=r"\s+")
It would be something like this.
String text = textArea.getText();
Scanner reader = new Scanner(text).useDelimiter("\n");
while(reader.hasNext())
String line = reader.next();
try{
Integer.parseInt(line);
//it worked
}
catch(NumberFormatException e){
//it failed
}
}
If your media query condition is true then your CSS with that condition will work. That means CSS within your media query's condition pixel size will effect, or else if the condition will fail that mean if the device's width is greater than 1024px than your CSS will not work.Because your media query condition false.
max-width
is your max CSS limit till that width.
You can use mmc:
At that point you will be able to manage services as if they were on your local machine.
If you are trying to make more than just one folder on the root of the sdcard,
ex. Environment.getExternalStorageDirectory() + "/Example/Ex App/"
then instead of folder.mkdir()
you would use folder.mkdirs()
I've made this mistake in the past & I took forever to figure it out.
The reason is one servlet container is already running on port 8080 and you are trying to run another one on port 8080.
Check what processes are running at available ports.
For Windows :
netstat -ao |find /i "listening"
OR
netstat -ano | find "8080"
(Note: 8080 is port fail to start)
Now try to reLaunch or stop your application.
Taskkill /F /IM 6592 Note: Mention correct Process Id
right click on the console and select terminate/disconnect all
Task Manager
and end Java(tm) platform se binaryAnother option is :
Go to application.properties
file set server.port=0
. This will cause Spring Boot to use a random free port every time it starts.
Style the row-element with css:
border-bottom: 1px solid black;
SET out_number=SQRT(input_number);
Instead of this write:
select SQRT(input_number);
Please don't write SET out_number
and your input parameter should be:
PROCEDURE `test`.`my_sqrt`(IN input_number INT, OUT out_number FLOAT)
I fixed the problem with deleting .vs folder on project folder.
VS will generate new config for this project.
(a) Django is a framework, not a language
(b) I'm not sure what you're missing - there is no reason why you can't have business logic in a web application. In Django, you would normally expect presentation logic to be separated from business logic. Just because it is hosted in the same application server, it doesn't follow that the two layers are entangled.
(c) Django does provide templating, but it doesn't provide rich libraries for generating client-side content.
You cannot directly see the query result using mysql_query its only fires the query in mysql nothing else.
For getting the result you have to add a lil things in your script like
require_once('db.php');
$sql="SELECT * FROM modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) ) FROM modul1open) ORDER BY idM1O LIMIT 1";
$result = mysql_query($sql);
//echo [$result];
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
print_r($row);
}
This will give you result;
Just telling you about one other possibility: I like using friend definitions for that:
namespace Math
{
class Matrix
{
public:
[...]
friend std::ostream& operator<< (std::ostream& stream, const Matrix& matrix) {
[...]
}
};
}
The function will be automatically targeted into the surrounding namespace Math
(even though its definition appears within the scope of that class) but will not be visible unless you call operator<< with a Matrix object which will make argument dependent lookup find that operator definition. That can sometimes help with ambiguous calls, since it's invisible for argument types other than Matrix. When writing its definition, you can also refer directly to names defined in Matrix and to Matrix itself, without qualifying the name with some possibly long prefix and providing template parameters like Math::Matrix<TypeA, N>
.
It may happen when you don't have any files. Try to create a text file then follow the following commands
git add .
git commit -m "first commit"
git push --set-upstream origin master
Thanks @vpekar for your implementation. It helped a lot. I just found that it misses the tf-idf weight while calculating the cosine similarity. The Counter(word) returns a dictionary which has the list of words along with their occurence.
cos(q, d) = sim(q, d) = (q · d)/(|q||d|) = (sum(qi, di)/(sqrt(sum(qi2)))*(sqrt(sum(vi2))) where i = 1 to v)
Please feel free to view my code here. But first you will have to download the anaconda package. It will automatically set you python path in Windows. Add this python interpreter in Eclipse.
Finally, Anaconda3-2020.07 is out and its core is Python 3.8!

Regarding the comment of Andrew Mairose - Although a fine solution, I would just like to add that this solution will not work on fixed size lists.
You could attempt doing like so:
Arrays.asList(new String[]{"a", "b", null, "c", " "})
.removeIf(item -> item == null || "".equals(item));
But you'll encounter an UnsupportedOperationException at java.util.AbstractList.remove
(since asList
returns a non-resizable List).
A different solution might be this:
List<String> collect =
Stream.of(new String[]{"a", "b", "c", null, ""})
.filter(item -> item != null && !"".equals(item))
.collect(Collectors.toList());
Which will produce a nice list of strings :-)
>>> df.groupby('id').first()
value
id
1 first
2 first
3 first

If you need id
as column:
>>> df.groupby('id').first().reset_index()
id value
0 1 first
1 2 first
2 3 first
3 4 second
4 5 first
5 6 first

To get n first records, you can use head():
>>> df.groupby('id').head(2).reset_index(drop=True)
id value
0 1 first
1 1 second
2 2 first
3 2 second

Just found this old thread, looking for some kind of escape sequence to blank the actual line.
It's quite funny no one came to the idea (or I have missed it) that printf returns the number of characters written. So just print '\r' + as many blank characters as printf returned and you will exactly blank the previuosly written text.
int BlankBytes(int Bytes)
{
char strBlankStr[16];
sprintf(strBlankStr, "\r%%%is\r", Bytes);
printf(strBlankStr,"");
return 0;
}
int main(void)
{
int iBytesWritten;
double lfSomeDouble = 150.0;
iBytesWritten = printf("test text %lf", lfSomeDouble);
BlankBytes(iBytesWritten);
return 0;
}
As I cant use VT100, it seems I have to stick with that solution

Well, for starters, you might not wanna overuse echo, because (as is the problem in your case) you can very easily make mistakes on quotation marks.
This would fix your problem:
echo "<a href=\"http://www.whatever.com/$param\">Click Here</a>";
but you should really do this
<?php
$param = "test";
?>
<a href="http://www.whatever.com/<?php echo $param; ?>">Click Here</a>
You have a few options:
c(vector, values)
append(vector, values)
vector[(length(vector) + 1):(length(vector) + length(values))] <- values
The first one is the standard approach. The second one gives you the option to append someplace other than the end. The last one is a bit contorted but has the advantage of modifying vector
(though really, you could just as easily do vector <- c(vector, values)
.
Notice that in R you don't need to cycle through vectors. You can just operate on them in whole.
Also, this is fairly basic stuff, so you should go through some of the references.
Some more options based on OP feedback:
for(i in values) vector <- c(vector, i)
See if the below helps you:
I was using the following earlier:
ClientScript.RegisterClientScriptBlock(Page.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>");
After implementing AJAX in this page, it stopped working. After reading your blog, I changed the above to:
ScriptManager.RegisterClientScriptBlock(imgBtnSubmit, this.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>", false);
This is working perfectly fine.

The .git
at the end of the repository name is just a convention. Typically, on git servers repositories are kept in directories named project.git
. The git client and protocol honours this convention by testing for project.git
when only project
is specified.
git://[email protected]/peter/first_app.git
is not a valid git url. git repositories can be identified and accessed via various url schemes specified here. [email protected]:peter/first_app.git
is the ssh
url mentioned on that page.
git
is flexible. It allows you to track your local branch against almost any branch of any repository. While master
(your local default branch) tracking origin/master
(the remote default branch) is a popular situation, it is not universal. Many a times you may not want to do that. This is why the first git push
is so verbose. It tells git what to do with the local master
branch when you do a git pull
or a git push
.
The default for git push
and git pull
is to work with the current branch's remote. This is a better default than origin master. The way git push determines this is explained here.
git
is fairly elegant and comprehensible but there is a learning curve to walk through.
if you are using XDocument.Load(url);
to fetch xml from another domain, it's possible that the host will reject the request and return and unexpected (non-xml) result, which results in the above XmlException
See my solution to this eventuality here: XDocument.Load(feedUrl) returns "Data at the root level is invalid. Line 1, position 1."
You can try the faulthandler module. Install it using pip install faulthandler
and add:
import faulthandler, signal
faulthandler.register(signal.SIGUSR1)
at the beginning of your program. Then send SIGUSR1 to your process (ex: kill -USR1 42
) to display the Python traceback of all threads to the standard output. Read the documentation for more options (ex: log into a file) and other ways to display the traceback.
The module is now part of Python 3.3. For Python 2, see http://faulthandler.readthedocs.org/
The problem may be with jquery selector you've chosen
$("video")
is not a selector
The right selector may be putting an id element for video tag i.e.
Let's say your video element looks like this:
<video id="vid1" width="480" height="267" oster="example.jpg" durationHint="33">
<source src="video1.ogv" />
<source src="video2.ogv" />
</video>
Then you can select it via $("#vid1")
with hash mark (#), id selector in jquery.
If a video element is exposed in function,then you have access to HtmlVideoElement (HtmlMediaElement).This elements has control over video element,in your case you can use pause()
method for your video element.
Check reference for VideoElement here.
Also check that there is a fallback reference here.
Your flex items have
flex: 0 0 200px; /* <aside> */
flex: 1 0 auto; /* <article> */
That means:
The <aside>
will start at 200px
wide.
Then it won't grow nor shrink.
The <article>
will start at the width given by the content.
Then, if there is available space, it will grow to cover it.
Otherwise it won't shrink.
To prevent horizontal overflow, you can:
flex-basis: 0
and then let them grow with a positive flex-grow
.flex-shrink
to let them shrink if there isn't enough space.To prevent vertical overflow, you can
min-height
instead of height
to allow the flex items grow more if necessaryoverflow
different than visible on the flex itemsoverflow

main, aside, article {
margin: 10px;

min-height: 50px; /* min-height instead of height */
}
main {
display: flex;

Although not a complete answer to your question, there are shortcut keys in Excel to change the formatting of the selected cell(s) to either Date or Time (unfortunately, I haven't found one for Date+Time).
So, if you're just looking for dates, you can perform the following:
Ctrl
+Shift
+3
For formatting as Times, use Ctrl
+Shift
+2
.
You can use this in SQL SERVER
SELECT CONVERT(nvarchar(19),ColumnName,121) AS [Changed On] FROM Table
I will throw my vote behind Raphael - the cross-browser support, clean API and consistent updates (so far) make it a joy to use. It plays very nicely with jQuery too. Processing is cool, but more useful as a demo for bleeding-edge stuff at the moment.
You need to call the
$.parseJSON();
For example:
...
success: function(data){
var json = $.parseJSON(data); // create an object with the key of the array
alert(json.html); // where html is the key of array that you want, $response['html'] = "<a>something..</a>";
},
error: function(data){
var json = $.parseJSON(data);
alert(json.error);
} ...
see this in http://api.jquery.com/jQuery.parseJSON/
if you still have the problem of slashes: search for security.magicquotes.disabling.php or: function.stripslashes.php
Note:
This answer here is for those who try to use $.ajax
with the dataType
property set to json
and even that got the wrong response type. Defining the header('Content-type: application/json');
in the server may correct the problem, but if you are returning text/html
or any other type, the $.ajax
method should convert it to json
. I make a test with older versions of jQuery and only after version 1.4.4
the $.ajax
force to convert any content-type to the dataType
passed. So if you have this problem, try to update your jQuery version.
According to the error message, you declared myLoc
as a pointer to an NSInteger (NSInteger *myLoc
) rather than an actual NSInteger (NSInteger myLoc
). It needs to be the latter.
You can use it to transform some aggregate functions into analytic:
SELECT MAX(date)
FROM mytable
will return 1
row with a single maximum,
SELECT MAX(date) OVER (ORDER BY id)
FROM mytable
will return all rows with a running maximum.
As Eric Wendelin mentioned, you can do something like this:
str1 = "pattern"
var re = new RegExp(str1, "g");
"pattern matching .".replace(re, "regex");
This yields "regex matching ."
. However, it will fail if str1 is "."
. You'd expect the result to be "pattern matching regex"
, replacing the period with "regex"
, but it'll turn out to be...
regexregexregexregexregexregexregexregexregexregexregexregexregexregexregexregexregexregex
This is because, although "."
is a String, in the RegExp constructor it's still interpreted as a regular expression, meaning any non-line-break character, meaning every character in the string. For this purpose, the following function may be useful:
RegExp.quote = function(str) {
return str.replace(/([.?*+^$[\]\\(){}|-])/g, "\\$1");
};
Then you can do:
str1 = "."
var re = new RegExp(RegExp.quote(str1), "g");
"pattern matching .".replace(re, "regex");
yielding "pattern matching regex"
.
The getElementsByClassName
method is now natively supported by the most recent versions of Firefox, Safari, Chrome, IE and Opera, you could make a function to check if a native implementation is available, otherwise use the Dustin Diaz method:
function getElementsByClassName(node,classname) {
if (node.getElementsByClassName) { // use native implementation if available
return node.getElementsByClassName(classname);
} else {
return (function getElementsByClass(searchClass,node) {
if ( node == null )
node = document;
var classElements = [],
els = node.getElementsByTagName("*"),
elsLen = els.length,
pattern = new RegExp("(^|\\s)"+searchClass+"(\\s|$)"), i, j;
for (i = 0, j = 0; i < elsLen; i++) {
if ( pattern.test(els[i].className) ) {
classElements[j] = els[i];
j++;
}
}
return classElements;
})(classname, node);
}
}
Usage:
function toggle_visibility(className) {
var elements = getElementsByClassName(document, className),
n = elements.length;
for (var i = 0; i < n; i++) {
var e = elements[i];
if(e.style.display == 'block') {
e.style.display = 'none';
} else {
e.style.display = 'block';
}
}
}

Your sys.path is kind of unusual, as each entry is prefixed with /usr/intel. I guess numpy is installed in the usual non-prefixed place, e.g. it. /usr/share/pyshared/numpy on my Ubuntu system.

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.
So if you want to use your code, you could do:
df = DataFrame(eval(data))
But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:
data = []
for row in result_set:
data.append({'value': row["tag_expression"], 'key': row["tag_name"]})
But probably even this is not needed, as depending on what is exactly in your result_set
you could probably:
DataFrame(result_set)

In the past when un managed nand was the most popular storage technology, yaffs2 was the most common file system. This days there are few devices using un-managed nand, and those still in use are slowly migrating to ubifs.
Today most common storage is emmc (managed nand), for such devices ext4 is far more popular, but, this file system is slowly clears its way for f2fs (flash friendly fs).
Edit: f2fs will probably won't make it as the common fs for flash devices (including android)
Just in case you have a preference for how negative numbers are formatted:
p "%x" % -1 #=> "..f"
p -1.to_s(16) #=> "-1"
I'd personally make use of the table.insert
function:
table.insert(a,"b");
This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time.

I have encountered problem installing numpy package to pycharm and finally figured out. I hope it would be helpful for someone having the same problem in installing numpy and other packages on pycharm.
Pycharm Setting :
Go to File => Setting => Project => Project Interpreter. On this window select the appropriate project interpreter. After this, a list of packages under the selected project interpreter will be shown. From the list select pip and check if the version column and the latest version column are the same. If different upgrade the version to the latest version by selecting the pip and using the upward triangle sign on the right side of the lists. Once the upgrading completed successfully, you can now add new packages from the plus sign.
I hope this would be clear and useful for someone.
You can also look at the SampleSyncAdapter sample from the SDK. It may help you.
users.toList().RemoveAll(user => <your condition>)
From the manual:
To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
Obviously, you should replace 95
by 10
. The large number they use is 2^64 - 1, by the way.
The generic Returns<T>
method can handle this situation nicely.
_mock.Setup(x => x.DoSomething(It.IsAny<string>())).Returns<string>(x => x);
Or if the method requires multiple inputs, specify them like so:
_mock.Setup(x => x.DoSomething(It.IsAny<string>(), It.IsAny<int>())).Returns((string x, int y) => x);
You can use:
$answer.replace(' ' , '')
or
$answer -replace " ", ""

I'd say vim is definitely worth learning. I picked it up last summer, and it is now my editor of choice for just about everything (java is a stretch, but doable when I don't need extensive analysis support). As everyone has already affirmed, it is a wonderfully efficient tool.
For what it's worth, I only learned a fairly small subset of vim's features (which took a day or two) from a graphical tutorial, and a few odds and ends from here (long read), and the search and replace functionality, and I was hooked. I've learned things since then, but at my leisure. I'd say the learning curve flattens out at this point, but then, I was using it pretty heavily and was surrounded by others who were, too.
One solution you could use is to assign a more generalized class to any div you want the click event handler bound to.
For example:
HTML:
<body>
<div id="dog" class="selected" data-selected="false">dog</div>
<div id="cat" class="selected" data-selected="true">cat</div>
<div id="mouse" class="selected" data-selected="false">mouse</div>
<div class="dog"><img/></div>
<div class="cat"><img/></div>
<div class="mouse"><img/></div>
</body>
JS:
$( ".selected" ).each(function(index) {
$(this).on("click", function(){
// For the boolean value
var boolKey = $(this).data('selected');
// For the mammal value
var mammalKey = $(this).attr('id');
});
});
HashMap<String, String> hashMap = new HashMap<>();
String[] stringValues= new String[hashMap.values().size()];
hashMap.values().toArray(stringValues);
Why not hide the input element and replace it with a label element with the same content?
I puzzled over how the React TODOMVC app accomplished this same thing and this is the strategy they came up with.
To see it in action, check out the app below, and watch the CSS properties of the TODO items when you double click them and then click away.

When you render the page you can have either an editable input, or a non-editable label with display:none; depending on your media query.
Instead of CharSet.forName, using com.google.common.base.Charsets from Google's Guava (http://code.google.com/p/guava-libraries/wiki/StringsExplained#Charsets) is is slightly nicer:
InputStream is = new ByteArrayInputStream( myString.getBytes(Charsets.UTF_8) );
Which CharSet you use depends entirely on what you're going to do with the InputStream, of course.
There are too many methods to check for hidden elements. This is the best choice (I just recommended you):
Using jQuery, make an element, "display:none", in CSS for hidden.
The point is:
$('element:visible')
And an example for use:
$('element:visible').show();

I would also use navigation.navigate. If someone has the same problem and also uses nested navigators, this is how it would work:

Have look at dom4j or jdom. Both libraries allow creating a Document and allow printing the document as xml. Both are widly used, pretty easy to use and you'll find a lot of examples and snippets.
You need something like this: https://github.com/axkibe/lsyncd It is a tool which combines rsync and inotify - the former is a tool that mirrors, with the correct options set, a directory to the last bit. The latter tells the kernel to notify a program of changes to a directory ot file. It says:
It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes.
But - according to Digital Ocean at https://www.digitalocean.com/community/tutorials/how-to-mirror-local-and-remote-directories-on-a-vps-with-lsyncd - it ought to be in the Ubuntu repository!
I have similar requirements, and this tool, which I have yet to try, seems suitable for the task.
There are many answers recommend to use: Array.prototype.push(a, b)
. It's nice way, BUT if you will have really big b, you will have stack overflow error (because of too many args). Be careful here.
See What is the most efficient way to concatenate N arrays? for more details.
Simple Example:
break
leaves the loop.
int m = 0;
for(int n = 0; n < 5; ++n){
if(n == 2){
break;
}
m++;
}
System.out.printl("m:"+m); // m:2
continue
will go back to start loop.
int m = 0;
for(int n = 0; n < 5; ++n){
if(n == 2){
continue; // Go back to start and dont execute m++
}
m++;
}
System.out.printl("m:"+m); // m:4
This should works
$token = "YOUR_BEARER_AUTH_TOKEN";

You can change directory using this command like : currently if you current working directoris c:\ drive the if you want to go to your D:\ drive then type this command
cd /d D:\
now your current working directory is D:\ drive so you want go to Java directory under Docs so type below command :
cd Docs\Java
note : d stands for drive
You can use datetime's strftime function to get this. The problem is that time's strftime accepts a timetuple that does not carry microsecond information.
from datetime import datetime
datetime.now().strftime("%H:%M:%S.%f")
Should do the trick!
I prefer just going into less

Even better: hit v to start editing (in vim, of course!), at that location. Now, note that vim

Might be helpful for those that tried using the deprecated method above.

That method must be called on the Dispose
method of objects that implements the IDisposable
, in this way the GC wouldn't call the finalizer another time if someones calls the Dispose
method.
The short answer is that not only is static
useful, it is pretty well always going to be desired.
First, note that static
and constexpr
are completely independent of each other. static
defines the object's lifetime during execution; constexpr
specifies that the object should be available during compilation. Compilation and execution are disjoint and discontiguous, both in time and space. So once the program is compiled, constexpr
is no longer relevant.
Every variable declared constexpr
is implicitly const
but const
and static
are almost orthogonal (except for the interaction with static const
integers.)
The C++
object model (§1.9) requires that all objects other than bit-fields occupy at least one byte of memory and have addresses; furthermore all such objects observable in a program at a given moment must have distinct addresses (paragraph 6). This does not quite require the compiler to create a new array on the stack for every invocation of a function with a local non-static const array, because the compiler could take refuge in the as-if
principle provided it can prove that no other such object can be observed.
That's not going to be easy to prove, unfortunately, unless the function is trivial (for example, it does not call any other function whose body is not visible within the translation unit) because arrays, more or less by definition, are addresses. So in most cases, the non-static const(expr)
array will have to be recreated on the stack at every invocation, which defeats the point of being able to compute it at compile time.
On the other hand, a local static const
object is shared by all observers, and furthermore may be initialized even if the function it is defined in is never called. So none of the above applies, and a compiler is free not only to generate only a single instance of it; it is free to generate a single instance of it in read-only storage.
So you should definitely use static constexpr
in your example.
However, there is one case where you wouldn't want to use static constexpr
. Unless a constexpr
declared object is either ODR-used or declared static
, the compiler is free to not include it at all. That's pretty useful, because it allows the use of compile-time temporary constexpr
arrays without polluting the compiled program with unnecessary bytes. In that case, you would clearly not want to use static
, since static
is likely to force the object to exist at runtime.
Or, KISS.

I suggest you create your own list of operator words that you take out of the stopword list. Sets can be conveniently subtracted, so:
operators = set(('and', 'or', 'not'))
stop = set(stopwords...) - operators
Then you can simply test if a word is in
or not in
the set without relying on whether your operators are part of the stopword list. You can then later switch to another stopword list or add an operator.
if word.lower() not in stop:
# use word
"top" is usually available on Solaris.
If not then revert to "vmstat" which is available on most UNIX system.
It should look something like this (from an AIX box)
vmstat System configuration: lcpu=4 mem=12288MB ent=2.00 kthr memory page faults cpu ----- ----------- ------------------------ ------------ ----------------------- r b avm fre re pi po fr sr cy in sy cs us sy id wa pc ec 2 1 1614644 585722 0 0 1 22 104 0 808 29047 2767 12 8 77 3 0.45 22.3
the colums "avm" and "fre" tell you the total memory and free memery.
a "man vmstat" should get you the gory details.
You can validate point a and b compactly by doing something like the following:
#!/bin/sh
MYVAL=$(echo ${1} | awk '/^[0-9]+$/')
MYVAL=${MYVAL:?"Usage - testparms <number>"}
echo ${MYVAL}
Which gives us ...
$ ./testparams.sh
Usage - testparms <number>
$ ./testparams.sh 1234
1234
$ ./testparams.sh abcd
Usage - testparms <number>
This method should work fine in sh.
In my project I'm doing this and it works fine:

For applications such as Squirrel SQL Client (http://squirrel-sql.sourceforge.net/) version 4 you can set "serverTimezone" under "driver properties" to GMT+1

If you don't want to modify the original object.
Remove a property without mutating the object
If mutability is a concern, you can create a completely new object by copying all the properties from the old, except the one you want to remove.
let myObject = {
"ircEvent": "PRIVMSG",
"method": "newURI",
"regex": "^http://.*"
};
let prop = 'regex';
const updatedObject = Object.keys(myObject).reduce((object, key) => {
if (key !== prop) {
object[key] = myObject[key]
}
return object
}, {})
console.log(updatedObject);

(question) Don't you get that info in
select * from pg_user;
or using the view pg_stat_activity:
select * from pg_stat_activity;
Added:
the view says:
One row per server process, showing database OID, database name, process ID, user OID, user name, current query, query's waiting status, time at which the current query began execution, time at which the process was started, and client's address and port number. The columns that report data on the current query are available unless the parameter stats_command_string has been turned off. Furthermore, these columns are only visible if the user examining the view is a superuser or the same as the user owning the process being reported on.
can't you filter and get that information? that will be the current users on the Database, you can use began execution time to get all queries from last 5 minutes for example...
something like that.
I know it's not your specific problem, but I faced the same symptoms when I configured a static IP address in the network adapter settings and forgot to enter a "Default Gateway".
Leaving the field blank, the network icon shows an Internet connection, and I could ping internal servers but not external ones, so I assumed it was a DNS problem. NSLookup still worked, but of course, ping failed to find the server (again, seemed like a DNS issue.) Anyway, one more thing to check. =P
Apart from custom class or .Net 4.0 Tuples, since C# 7.0 there is a new feature called ValueTuple, which is a struct that can be used in this case. Instead of writing:
Tuple<string, int> t = new Tuple<string, int>("Hello", 4);
and access values through t.Item1
and t.Item2
, you can simply do it like that:
(string message, int count) = ("Hello", 4);
or even:
(var message, var count) = ("Hello", 4);
Your formula generates numbers between min and min + max.
The one Google found generates numbers between min and max.
Google wins!
Also, change this:
SelBranchVal = SelBranchVal + "," + InvForm.SelBranch[x].value;
to
SelBranchVal = SelBranchVal + InvForm.SelBranch[x].value+ "," ;

will be empty
UNIT TESTING
Unit testing includes testing of smallest unit of code which usually are functions or methods. Unit testing is mostly done by developer of unit/method/function, because they understand the core of a function. The main goal of the developer is to cover code by unit tests.
It has a limitation that some functions cannot be tested through unit tests. Even after the successful completion of all the unit tests; it does not guarantee correct operation of the product. The same function can be used in few parts of the system while the unit test was written only for one usage.
FUNCTIONAL TESTING
It is a type of Black Box testing where testing will be done on the functional aspects of a product without looking into the code. Functional testing is mostly done by a dedicated Software tester. It will include positive, negative and BVA techniques using un standardized data for testing the specified functionality of product. Test coverage is conducted in an improved manner by functional tests than by unit tests. It uses application GUI for testing, so it’s easier to determine what exactly a specific part of the interface is responsible for rather to determine what a code is function responsible for.

The SSA is instituting a new policy the where all previously unused sequences are will be available for use.
Goes into affect June 25, 2011.
Taken from the new FAQ:
What changes will result from randomization?
The SSA will eliminate the geographical significance of the first three digits of the SSN, currently referred to as the area number, by no longer allocating the area numbers for assignment to individuals in specific states. The significance of the highest group number (the fourth and fifth digits of the SSN) for validation purposes will be eliminated. Randomization will also introduce previously unassigned area numbers for assignment excluding area numbers 000, 666 and 900-999. Top
Will SSN randomization assign group number (the fourth and fifth digits of the SSN) 00 or serial number (the last four digits of the SSN) 0000?
SSN randomization will not assign group number 00 or serial number 0000. SSNs containing group number 00 or serial number 0000 will continue to be invalid.

In my case ,I created a project and made its minSdkVersion=9
and targetSdkVersion=17
. I used automatically generated libs/android-support-v4.jar
. I also had to make use of ActionBarActivity
using android-support-v7-appcomapt.jar
. So I just copied the android-support-v7-appcompat.jar
file from android-sdk/extras/andrid/support/v7/appcompat/libs
folder and pasted it to my project libs
folder. And this caused the above error.
So basically,I needed to put android-support-v4.jar
file from android-sdk/extras/andrid/support/v7/appcompat/libs
as well to my project libs
folder. As per my knowledge the v7.jar
file had dependencies on v4.jar
file. So ,it needed it own v4.jar
file,instead of my project,automatically created v4.jar
file.
Generally, I agree with @kgrittn's advice. Go for it.
But to address your basic question about concat()
: The new function concat()
is useful if you need to deal with null values - and null has neither been ruled out in your question nor in the one you refer to.
If you can rule out null values, the good old (SQL standard) concatenation operator ||
is still the best choice, and @luis' answer is just fine:
SELECT col_a || col_b;
If either of your columns can be null, the result would be null in that case. You could defend with COALESCE
:
SELECT COALESCE(col_a, '') || COALESCE(col_b, '');
But that get tedious quickly with more arguments. That's where concat()
comes in, which never returns null, not even if all arguments are null. Per documentation:
NULL arguments are ignored.
SELECT concat(col_a, col_b);
The remaining corner case for both alternatives is where all input columns are null in which case we still get an empty string ''
, but one might want null instead (at least I would). One possible way:
SELECT CASE
WHEN col_a IS NULL THEN col_b
WHEN col_b IS NULL THEN col_a
ELSE col_a || col_b
END;
This gets more complex with more columns quickly. Again, use concat()
but add a check for the special condition:
SELECT CASE WHEN (col_a, col_b) IS NULL THEN NULL
ELSE concat(col_a, col_b) END;
How does this work?
(col_a, col_b)
is shorthand notation for a row type expression ROW (col_a, col_b)
. And a row type is only null if all columns are null. Detailed explanation:
Also, use concat_ws()
to add separators between elements (ws
for "with separator").
An expression like the one in Kevin's answer:
SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;
is tedious to prepare for null values in PostgreSQL 8.3 (without concat()
). One way (of many):
SELECT COALESCE(
CASE
WHEN $1.zipcode IS NULL THEN $1.city
WHEN $1.city IS NULL THEN $1.zipcode
ELSE $1.zipcode || ' - ' || $1.city
END, '')
|| COALESCE(', ' || $1.state, '');
STABLE
concat()
and concat_ws()
are STABLE
functions, not IMMUTABLE
because they can invoke datatype output functions (like timestamptz_out
) that depend on locale settings.
Explanation by Tom Lane.
This prohibits their direct use in index expressions. If you know that the result is actually immutable in your case, you can work around this with an IMMUTABLE
function wrapper. Example here:
You could use the Description
attribute, as Yuriy suggested. The following extension method makes it easy to get the description for a given value of the enum:
public static string GetDescription(this Enum value)
{
Type type = value.GetType();
string name = Enum.GetName(type, value);
if (name != null)
{
FieldInfo field = type.GetField(name);
if (field != null)
{
DescriptionAttribute attr =
Attribute.GetCustomAttribute(field,
typeof(DescriptionAttribute)) as DescriptionAttribute;
if (attr != null)
{
return attr.Description;
}
}
}
return null;
}
You can use it like this:
public enum MyEnum
{
[Description("Description for Foo")]
Foo,
[Description("Description for Bar")]
Bar
}
MyEnum x = MyEnum.Foo;
string description = x.GetDescription();

Specify "required" keyword in one of the select statements. If you want to change the default way of its appearance. You can follow these steps. This is just for extra info if you have any intention to modify the default behavior.
Add the following into you .css
file.
/* style all elements with a required attribute */
:required {
background: red;
}
For more information you can refer following URL.
ContactNumbers = new List<ContactNumber>();
If you want it to be passed in, just take
public Human(List<ContactNumber> numbers)
{
ContactNumbers = numbers;
}
Added for reference to future people who find this via google: You might want to look at the {% overextend %} tag provided by the mezzanine library for cases like this.
Here's a working solution (2019): put this code inside your login logic;
GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject json, GraphResponse response) {
// Application code
if (response.getError() != null) {
System.out.println("ERROR");
} else {
System.out.println("Success");
String jsonresult = String.valueOf(json);
System.out.println("JSON Result" + jsonresult);
String fbUserId = json.optString("id");
String fbUserFirstName = json.optString("name");
String fbUserEmail = json.optString("email");
//String fbUserProfilePics = "http://graph.facebook.com/" + fbUserId + "/picture?type=large";
Log.d("SignUpActivity", "Email: " + fbUserEmail + "\nName: " + fbUserFirstName + "\nID: " + fbUserId);
}
Log.d("SignUpActivity", response.toString());
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
setResult(RESULT_CANCELED);
Toast.makeText(SignUpActivity.this, "Login Attempt Cancelled", Toast.LENGTH_SHORT).show();
}
@Override
public void onError(FacebookException error) {
Toast.makeText(SignUpActivity.this, "An Error Occurred", Toast.LENGTH_LONG).show();
error.printStackTrace();
}
});
In my case solution was on iframe class adding:
display: block;
margin-right: auto;
margin-left: auto;
Here is a very simple way (3 lines of code) using the Fullscreen API and RequestFullscreen method that I used, which is compatible across all popular browsers:
var elem = document.getElementsByTagName('video')[0];_x000D_
var fullscreen = elem.webkitRequestFullscreen || elem.mozRequestFullScreen || elem.msRequestFullscreen;_x000D_
fullscreen.call(elem); // bind the 'this' from the video object and instantiate the correct fullscreen method.
_x000D_
If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.
To trigger an event after ng-repeat has rendered try this directive:
var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
restrict: 'A',
link: function (scope, element, attr) {
if (scope.$last === true) {
$timeout(function () {
scope.$emit('ngRepeatFinished');
});
}
}
}
});
Complete example in angular: http://jsfiddle.net/ADukg/6880/
I got the directive from here: Use AngularJS just for routing purposes
If it wasn't checked in as a Java Project, you can add the java nature as shown here.
<input type="hidden" id="date"/>
<script>document.getElementById("date").value = new Date().toJSON().slice(0,10)</script>
if (select == "") {
alert("Please select a selection");
return false;
That should work for you. It just did for me.
Read line by line, not the whole file:
for line in open(file_name, 'rb'):
# process line here
Even better use with
for automatically closing the file:
with open(file_name, 'rb') as f:
for line in f:
# process line here
The above will read the file object using an iterator, one line at a time.
This is my personal solution, based on the information here (this thread):
var Divs = new Array();
var Elemns = document.getElementsByClassName("divisao");
try {
Divs = Elemns.prototype.slice.call(Elemns);
} catch(e) {
Divs = $A(Elemns);
}
Where $A was described by Gareth Davis in his post:
function $A(iterable) {
if (!iterable) return [];
if ('toArray' in Object(iterable)) return iterable.toArray();
var length = iterable.length || 0, results = new Array(length);
while (length--) results[length] = iterable[length];
return results;
}
If browser supports the best way, ok, otherwise will use the cross browser.
Pseudocode
var ifr = document.createElement('iframe');
var frm = document.createElement('form');
frm.setAttribute("action", "yoururl");
frm.setAttribute("method", "post");
// create hidden inputs, add them
// not shown, but similar (create, setAttribute, appendChild)
ifr.appendChild(frm);
document.body.appendChild(ifr);
frm.submit();
You probably want to style the iframe, to be hidden and absolutely positioned. Not sure cross site posting will be allowed by the browser, but if so, this is how to do it.
Using modernizr
Modernizr.addTest('ie', function () {
var ua = window.navigator.userAgent;
var msie = ua.indexOf('MSIE ') > 0;
var ie11 = ua.indexOf('Trident/') > 0;
var ie12 = ua.indexOf('Edge/') > 0;
return msie || ie11 || ie12;
});
Ensure debug mode is on - either add APP_DEBUG=true
to .env file or set an environment variable
Log files are in storage/logs folder. laravel.log
is the default filename. If there is a permission issue with the log folder, Laravel just halts. So if your endpoint generally works - permissions are not an issue.
In case your calls don't even reach Laravel or aren't caused by code issues - check web server's log files (check your Apache/nginx config files to see the paths).
If you use PHP-FPM, check its log files as well (you can see the path to log file in PHP-FPM pool config).
So this may not be the issue for you, but I was struggling with this error. I discovered what was causing my problem, though I can't really explain as to why.
For me, mysqli_connect was working fine where the connection was made on pages in any various sub-directory. For some reason though, the same code referenced on pages in the root directory was returning this error. The strange thing is that it was working fine on my localhost environment in MAMP in the root directory, however on my shared host it was not.
After struggling to figure out what was giving me "Error 500" white screen from this "PHP Fatal Error," I went through the code and stumbled upon this code in the error handling that was suggested by the PHP Manual (https://www.php.net/manual/en/mysqli.error.php).
if (!mysqli_query($link, "SET a=1")) {
printf("Error message: %s\n", mysqli_error($link));
}
I randomly decided to remove it and, voila, connection to the database working in root directories. Maybe someone smarter than me can explain this, for anyone struggling with a similar issue.
At the time of writing this I have discovered that chromedriver 2.46 or 2.36 works well with Chrome 75.0.3770.100
Documentation here: http://chromedriver.chromium.org/downloads states align driver and browser alike but I found I had issues even with the most up-to-date driver when using Chrome 75
I am running Selenium 2 on Windows 10 Machine.
