First of all, use INTEL x86... this as CPU/ABI. Secondly, uncheck Snapshot if it is checked. Keep the Target upto Android 4.2.2
Windows 10 Solution:
For me this issue was due to downloading and creating an AVD using Android Studio and then trying to use that virtual device with the Ionic command line. I resolved this by deleting all existing emulators and creating a new one from the command line.
(the avdmanager file typically lives in C:\Users\\Android\sdk\tools\bin)
List existing emulators: avdmanager list avd
Delete an existing emulator: avdmanager delete avd -n emulator_name
Add system image: sdkmanager "system-images;android-24;default;x86_64"
Create new emulator: sdkmanager "system-images;android-27;google_apis_playstore;x86"
If it is a string
then use the built in float
on it to do the conversion for instance:
print( "%.5f" % float("1.43572e-03"))

According to me, this would happen if there are two offending classes of same name but with different version. Usually, it happens due to servlet-api.jar. If its present in lib folder of your war, then pls remove it using whichever tool used for building war. Or in case of maven, add the dependency with scope specified as "provided". This will solve the compilation issue and at run time it will refer to jar provided by server environment. Pls configure the dependency as follows:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>

$('.integerOnly').keyup(function (event) { //This is to protect if user copy-pastes some character value ,..
valKeyUp = this.value; //In that case, pasted text is replaced with old value,
if (!new RegExp('^[0-9]*$').test(valKeyUp)) { //which is stored in 'valKeyDown' at keydown event.
$(this).val(valKeyDown); //It is not possible to check this inside 'integerOnly' function as,
} //one cannot get the text printed by keydown event
}); //(that's why, this is checked on keyup)
$('.integerOnly').bind('input propertychange', function(e) { //if user copy-pastes some character value using mouse
valKeyUp = this.value;
if (!new RegExp('^[0-9]*$').test(valKeyUp)) {

The above code worked for me. On mobile browsers, when the user clicked on the back button, we wanted to restore the page state as per his previous visit.
Following is a simple working example to explain how standarization calculation works. The theory part is already well explained in other answers.
>>>import numpy as np
>>>data = [[6, 2], [4, 2], [6, 4], [8, 2]]
>>>a = np.array(data)
>>>np.std(a, axis=0)
array([1.41421356, 0.8660254 ])
>>>np.mean(a, axis=0)
array([6. , 2.5])
>>>from sklearn.preprocessing import StandardScaler
>>>scaler = StandardScaler()
>>>scaler.fit(data)
>>>print(scaler.mean_)
#Xchanged = (X-µ)/s WHERE s is Standard Deviation and µ is mean
>>>z=scaler.transform(data)
>>>z
Calculation
As you can see in the output, mean is [6. , 2.5] and std deviation is [1.41421356, 0.8660254 ]
Data is (0,1) position is 2 Standardization = (2 - 2.5)/0.8660254 = -0.57735027
Data in (1,0) position is 4 Standardization = (4-6)/1.41421356 = -1.414
Result After Standardization
Check Mean and Std Deviation After Standardization
Note: -2.77555756e-17 is very close to 0.

Chrome doesn't render the fonts like Firefox or any other browser does. This is generally a problem in Chrome running on Windows only. If you want to make the fonts smooth, use the -webkit-font-smoothing
property on yer h4
tags like this.
h4 {
-webkit-font-smoothing: antialiased;
}
You can also use subpixel-antialiased
, this will give you different type of smoothing (making the text a little blurry/shadowed). However, you will need a nightly version to see the effects. You can learn more about font smoothing here.
you may also try full xpath, I had a similar issue where I had to click on an element which has a property javascript onclick function. the full xpath method worked and no interactable exception was thrown.
I would use submodules (as Pat Notz) or two distinct repositories. If you modify your binary files too often, then I would try to minimize the impact of the huge repository cleaning the history:
I had a very similar problem several months ago: ~21 GB of MP3 files, unclassified (bad names, bad id3's, don't know if I like that MP3 file or not...), and replicated on three computers.
I used an external hard disk drive with the main Git repository, and I cloned it into each computer. Then, I started to classify them in the habitual way (pushing, pulling, merging... deleting and renaming many times).
At the end, I had only ~6 GB of MP3 files and ~83 GB in the .git directory. I used git-write-tree
and git-commit-tree
to create a new commit, without commit ancestors, and started a new branch pointing to that commit. The "git log" for that branch only showed one commit.
Then, I deleted the old branch, kept only the new branch, deleted the ref-logs, and run "git prune": after that, my .git folders weighted only ~6 GB...
You could "purge" the huge repository from time to time in the same way: Your "git clone"'s will be faster.
solution is easy:
replace
mask = (50 < df['heart rate'] < 101 &
140 < df['systolic blood pressure'] < 160 &
90 < df['dyastolic blood pressure'] < 100 &
35 < df['temperature'] < 39 &
11 < df['respiratory rate'] < 19 &
95 < df['pulse oximetry'] < 100
, "excellent", "critical")
by
mask = ((50 < df['heart rate'] < 101) &
(140 < df['systolic blood pressure'] < 160) &
(90 < df['dyastolic blood pressure'] < 100) &
(35 < df['temperature'] < 39) &
(11 < df['respiratory rate'] < 19) &
(95 < df['pulse oximetry'] < 100)
, "excellent", "critical")
For SQL Server 2005 and above use Coalesce for nulls
and I am using Cast or Convert if there are numeric values
-
declare @CodeNameString nvarchar(max)
select @CodeNameString = COALESCE(@CodeNameString + ',', '') + Cast(CodeName as varchar) from AccountCodes ORDER BY Sort
select @CodeNameString
This probably isn't the most elegant way to do it, but it gets the job done.

You Can Too Do This:
Step 1)Convert Your Private Channel To Public Channel
Step 2)Set The ChannelName For This Channel
Step 3)then you Can change this Channel to Private
Step 4)Now Sending Your Message Using @ChannelName That you Set In Step 3
note:For Step 1 You Can Change One of Your Public Channel To Private For a short time.
you can use this code
if (DecimalVariable.Equals(null))
{
//something statements
}
In Visual Studio Code you can:
Explorer
Select for compare
Compare with '[NAME OF THE PREVIOUSLY SELECTED FILE]'
This is something I need all the time so I created a bash function for it. It's based on glenn jackman's answer.
Add this to your .bash_profile etc.
function regex { gawk 'match($0,/'$1'/, ary) {print ary['${2:-'0'}']}'; }
Capture regex for each line in file
$ cat filename | regex '.*'
Capture 1st regex capture group for each line in file
$ cat filename | regex '(.*)' 1
Another way you can do even if someone already provide Java 8 walk.
This one will provide you all files recursively
private Stream<File> files(File file) {
return file.isDirectory()
? Arrays.stream(file.listFiles()).flatMap(this::files)
: Stream.of(file);
}
That code doesn't work very well i fixed it a little bit
var el = $('.caja-pago');
var elpos_original = el.offset().top;
$(window).scroll(function(){
var elpos = el.offset().top;
var windowpos = $(window).scrollTop();
var finaldestination = windowpos;
if(windowpos<elpos_original) {
finaldestination = elpos_original;
el.stop().animate({'top':400},500);
} else {
el.stop().animate({'top':windowpos+10},500);
}
});
You may need to upgrade your mongo shell. I had version 2.4.9 of the mongo shell locally, and I got this error trying to connect to a mongo 3 database. Upgrading the shell version to 3 solved the problem.
Sphinx is mainly a tool for formatting docs written independently from the source code, as I understand it.
For generating API docs from Python docstrings, the leading tools are pdoc and pydoctor. Here's pydoctor's generated API docs for Twisted and Bazaar.
Of course, if you just want to have a look at the docstrings while you're working on stuff, there's the "pydoc" command line tool and as well as the help()
function available in the interactive interpreter.
I'm learning about async/await, and ran into a situation where I need to call an async method synchronously. How can I do that?
The best answer is you don't, with the details dependent on what the "situation" is.
Is it a property getter/setter? In most cases, it's better to have asynchronous methods than "asynchronous properties". (For more info, see my blog post on asynchronous properties).
Is this an MVVM app and you want to do asynchronous data binding? Then use something like my NotifyTask
, as described in my MSDN article on asynchronous data binding.
Is it a constructor? Then you probably want to consider an asynchronous factory method. (For more info, see my blog post on asynchronous constructors).
There's almost always a better answer than to do sync-over-async.
If it's not possible for your situation (and you know this by asking a question here describing the situation), then I'd recommend just using synchronous code. Async all the way is best; sync all the way is second-best. Sync-over-async is not recommended.
However, there are a handful of situations where sync-over-async is necessary. Specifically, you are constrained by the calling code so that you have to be sync (and have absolutely no way to re-think or re-structure your code to allow asynchrony), and you have to call async code. This is a very rare situation, but it does come up from time to time.
In that case, you would need to use one of the hacks described in my article on brownfield async
development, specifically:
GetAwaiter().GetResult()
). Note that this can cause deadlocks (as I describe on my blog).Task.Run(..).GetAwaiter().GetResult()
). Note that this will only work if the asynchronous code can be run on a thread pool thread (i.e., is not dependent on a UI or ASP.NET context).Nested message loops are the most dangerous of all the hacks, because it causes re-entrancy. Re-entrancy is extremely tricky to reason about, and (IMO) is the cause of most application bugs on Windows. In particular, if you're on the UI thread and you block on a work queue (waiting for the async work to complete), then the CLR actually does some message pumping for you - it'll actually handle some Win32 messages from within your code. Oh, and you have no idea which messages - when Chris Brumme says "Wouldn’t it be great to know exactly what will get pumped? Unfortunately, pumping is a black art which is beyond mortal comprehension.", then we really have no hope of knowing.
So, when you block like this on a UI thread, you're asking for trouble. Another cbrumme quote from the same article: "From time to time, customers inside or outside the company discover that we are pumping messages during managed blocking on an STA [UI thread]. This is a legitimate concern, because they know that it’s very hard to write code that’s robust in the face of reentrancy."
Yes, it is. Very hard to write code that's robust in the face of reentrancy. And nested message loops force you to write code that's robust in the face of reentrancy. This is why the accepted (and most-upvoted) answer for this question is extremely dangerous in practice.
If you are completely out of all other options - you can't redesign your code, you can't restructure it to be async - you are forced by unchangeable calling code to be sync - you can't change the downstream code to be sync - you can't block - you can't run the async code on a separate thread - then and only then should you consider embracing reentrancy.
If you do find yourself in this corner, I would recommend using something like Dispatcher.PushFrame
for WPF apps, looping with Application.DoEvents
for WinForm apps, and for the general case, my own AsyncContext.Run
.
Use a HashSet<string>
instead of a List<string>
. It is prepared to perform a better performance because you don't need to provide checks for any items. The collection will manage it for you. That is the difference between a list
and a set
. For sample:
HashSet<string> set = new HashSet<string>();
set.Add("a");
set.Add("a");
set.Add("b");
set.Add("c");
set.Add("b");
set.Add("c");
set.Add("a");
set.Add("d");
set.Add("e");
set.Add("e");
var total = set.Count;
Total is 5
and the values are a
, b
, c
, d
, e
.
The implemention of List<T>
does not give you nativelly. You can do it, but you have to provide this control. For sample, this extension method
:
public static class CollectionExtensions
{
public static void AddItem<T>(this List<T> list, T item)
{
if (!list.Contains(item))
{
list.Add(item);
}
}
}
and use it:
var list = new List<string>();
list.AddItem(1);
list.AddItem(2);
list.AddItem(3);
list.AddItem(2);
list.AddItem(4);
list.AddItem(5);
As i have implemented, and it is working fine. you just need to add column width using matColumnDef="description"
for example :
<mat-table #table [dataSource]="dataSource" matSortDisableClear>
<ng-container matColumnDef="productId">
<mat-header-cell *matHeaderCellDef>product ID</mat-header-cell>
<mat-cell *matCellDef="let product">{{product.id}}</mat-cell>
</ng-container>
<ng-container matColumnDef="productName">
<mat-header-cell *matHeaderCellDef>Name</mat-header-cell>
<mat-cell *matCellDef="let product">{{product.name}}</mat-cell>
</ng-container>
<ng-container matColumnDef="actions">
<mat-header-cell *matHeaderCellDef>Actions</mat-header-cell>
<mat-cell *matCellDef="let product">
<button (click)="view(product)">
<mat-icon>visibility</mat-icon>
</button>
</mat-cell>
</ng-container>
<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
<mat-row *matRowDef="let row; columns: displayedColumns"></mat-row>
</mat-table>
here matColumnDef
is
productId
, productName
and action
now we apply width by matColumnDef
styling
.mat-column-productId {
flex: 0 0 10%;
}
.mat-column-productName {
flex: 0 0 50%;
}
and remaining width is equally allocated to other columns
Two ways of dealing with it
div
inside tbody
tagdiv
inside tr
tagBoth approaches are valid, if you see feference: https://stackoverflow.com/a/23440419/2305243
If array is type of objects, then the simplest way is
let foo_object // Item to remove
this.foo_objects = this.foo_objects.filter(obj => obj !== foo_object);
If at all possible, its always a good idea to create your XML using the XML classes rather than string manipulation - one of the benefits being that the classes will automatically escape characters as needed.
You convert type np.dot(X, T)
to float32 like this:
z=np.array(np.dot(X, T),dtype=np.float32)
def sigmoid(X, T):
return (1.0 / (1.0 + np.exp(-z)))
Hopefully it will finally work!
You can get errors working correctly without hacking global.cs, messing with HandleErrorAttribute, doing Response.TrySkipIisCustomErrors, hooking up Application_Error, or whatever:
In system.web (just the usual, on/off)
<customErrors mode="On">
<error redirect="/error/401" statusCode="401" />
<error redirect="/error/500" statusCode="500" />
</customErrors>
and in system.webServer
<httpErrors existingResponse="PassThrough" />
Now things should behave as expected, and you can use your ErrorController to display whatever you need.
There is another solution you can try by using only the css here is the answer i posted in another post: jQuery Accordion change font awesome icon class on click
Short version of (correct) tzaman answer will be (for fresh SVN)
svn switch ^/branches/v1p2p3
--relocate
switch is deprecated anyway, when it needed you'll have to use svn relocate
command
Instead of creating snapshot-branch (ReadOnly) you can use tags (conventional RO labels for history)
On Windows, the caret character (^
) must be escaped:
svn switch ^^/branches/v1p2p3
The easiest way I found to fix this was to set the height of the body and html elements to 100.1% for any request where the user agent was an iphone. This only works in Landscape mode, but thats all I needed.
html.iphone,
html.iphone body { height: 100.1%; }
Check it out at https://www.360jungle.com/virtual-tour/25
So it would become:
List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
Iterator<Integer> myListIterator = myCoords.iterator();
while (myListIterator.hasNext()) {
Integer coord = myListIterator.next();
System.out.print("\r" + coord);
try{
Thread.sleep(2000);
}catch(Exception e){
// handle the exception...
}
}
}
Assuming you've fixed the syntax errors (you've closed the select box before the name attribute), you're using the same name for the select box as the submit button. Give the select box a different name.
map<string,string>m;
auto it=m.begin();//get iterator to the first element of map(m)
return m->first;//return first string(1st string in map<string,string>m)
//Incase you want the second string
//you can use return m->second(2st string in map<string,string>m)
//if you want to iterate the whole map you can use loop
for(auto it:m)//m is a map
cout<<it->first<<endl;
There is no best way, it depends on your use case.
Person
(you should start the name with a capital letter) is called the constructor function. This is similar to classes in other OO languages.Update: As requested examples for the third way.
Dependent properties:
The following does not work as this
does not refer to book
. There is no way to initialize a property with values of other properties in a object literal:
var book = {
price: somePrice * discount,
pages: 500,
pricePerPage: this.price / this.pages
};
instead, you could do:
var book = {
price: somePrice * discount,
pages: 500
};
book.pricePerPage = book.price / book.pages;
// or book['pricePerPage'] = book.price / book.pages;
Dynamic property names:
If the property name is stored in some variable or created through some expression, then you have to use bracket notation:
var name = 'propertyName';
// the property will be `name`, not `propertyName`
var obj = {
name: 42
};
// same here
obj.name = 42;
// this works, it will set `propertyName`
obj[name] = 42;
Since you are using jQuery you can use this onClick handler which calls click
:
$("#datepicker").click()
This is the same as $("#datepicker").trigger("click")
.
For a jQuery-free version check out this answer on SO.
If you're open to using jQuery:
<script type="text/javascript">
function fncsave()
{
$('#<%= savebtn.ClientID %>').click();
}
</script>
Also, if you are using .NET 4 or better you can make the ClientIDMode == static
and simplify the code:
<script type="text/javascript">
function fncsave()
{
$("#savebtn").click();
}
</script>
Reference: MSDN Article for Control.ClientIDMode
Assuming you have the following constructor
class MyClass {
public MyClass(Long l, String s, int i) {
}
}
You will need to show you intend to use this constructor like so:
Class classToLoad = MyClass.class;
Class[] cArg = new Class[3]; //Our constructor has 3 arguments
cArg[0] = Long.class; //First argument is of *object* type Long
cArg[1] = String.class; //Second argument is of *object* type String
cArg[2] = int.class; //Third argument is of *primitive* type int
Long l = new Long(88);
String s = "text";
int i = 5;
classToLoad.getDeclaredConstructor(cArg).newInstance(l, s, i);
ARIA (Accessible Rich Internet Applications) defines a way to make Web content and Web applications more accessible to people with disabilities.
The hidden
attribute is new in HTML5 and tells browsers not to display the element. The aria-hidden
property tells screen-readers if they should ignore the element. Have a look at the w3 docs for more details:
https://www.w3.org/WAI/PF/aria/states_and_properties#aria-hidden
Using these standards can make it easier for disabled people to use the web.
Have you tried the =DateValue()
function?
To include time value, just add the functions together:
=DateValue(A1)+TimeValue(A1)
In file /etc/ssh/sshd_config
# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no
Uncomment the second line, and, if needed, change yes to no.
Then run
service ssh restart
This worked for me:
var backgroundColor = window.getComputedStyle ? window.getComputedStyle(myDiv, null).getPropertyValue("background-color") : myDiv.style.backgroundColor;
And, even better:
var getStyle = function(element, property) {
return window.getComputedStyle ? window.getComputedStyle(element, null).getPropertyValue(property) : element.style[property.replace(/-([a-z])/g, function (g) { return g[1].toUpperCase(); })];
};
var backgroundColor = getStyle(myDiv, "background-color");
This below code will give selected row, you can parse the values from it and send to the AJAX call.
$(".selected").click(function () {
var row = $(this).parent().parent().parent().html();
});
here is my solution:
$(el).on('touchstart', function(e) {
var link = $(e.target.parentNode).closest('a')
if(link.length > 0) {
window.location.href = link.attr('href');
}
});
Use the pandas.DataFrame.round() method like this:
df = df.round({'value1': 0})
Any columns not included will be left as is.
It is already said in other answers . I did it like placing Spinner inside a CardView and changed the cardBackgroundColor . You could use some other views also and set its background either drawable or color . Thus it doesn't affect Spinner drop down arrow. As the spinner dropdown arrow disappears if we set background to Spinner.
<androidx.cardview.widget.CardView
android:id="@+id/cardView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:cardCornerRadius="6dp"
app:cardBackgroundColor="@color/white">
<Spinner
android:id="@+id/spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"/>
</androidx.cardview.widget.CardView>
Ugh, just spent an hour trying to figure this out. In my case I had a background set, however it was set to a color. This is not enough, you need to have the background of the view set to a drawable.
e.g. This won't have a shadow:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="165dp"
android:background="@color/ight_grey"
android:elevation="20dp"
android:orientation="vertical"
/>
but this will
<LinearLayout
android:layout_width="match_parent"
android:layout_height="165dp"
android:background="@drawable/selector_grey"
android:elevation="20dp"
android:orientation="vertical"
/>
EDIT: Have also discovered that if you use a selector as a background, if you don't have the corner set then the shadow won't show up in the Preview window but it will show up on the device
e.g. This doesn't have a shadow in preview:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="@color/white" />
<stroke
android:width="1dp"
android:color="@color/grey"/>
</shape>
</item>
</selector>
but this does:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="@color/white" />
<corners android:radius="1dp" />
<stroke
android:width="1dp"
android:color="@color/grey"/>
</shape>
</item>
</selector>
you should use "append" mode redirection >>
instead of >
Many of these solutions here ignore git
version tags which still means you have to track version in multiple places (bad). I approached this with the following goals:
git
repogit tag
/push
and setup.py upload
steps with a single command that takes no inputs.From a make release
command, the last tagged version in the git repo is found and incremented. The tag is pushed back to origin
.
The Makefile
stores the version in src/_version.py
where it will be read by setup.py
and also included in the release. Do not check _version.py
into source control!
setup.py
command reads the new version string from package.__version__

This does the heavy lifting how to process and increment the version number from git
.
The my_module/_version.py
file is imported into my_module/__init__.py
. Put any static install config here that you want distributed with your module.
from ._version import __version__
__author__ = ''
__email__ = ''
The last step is to read the version info from the my_module
module.
from setuptools import setup, find_packages
pkg_vars = {}
with open("{MODULE}/_version.py") as fp:
exec(fp.read(), pkg_vars)
setup(
version=pkg_vars['__version__'],
...
...
)
Of course, for all of this to work you'll have to have at least one version tag in your repo to start.
git tag -a v0.0.1
go to Services, find SQL Server Browser, right click --> Properties --> General tab --> Startup Type --> select automatic . Then go back to configuration management, start it.

You have to use Javascript Filereader for this. (Introduction into filereader-api: http://www.html5rocks.com/en/tutorials/file/dndfiles/)
Once the user have choose a image you can read the file-path of the chosen image and place it into your html.
Example:
<form id="form1" runat="server">
<input type='file' id="imgInp" />
<img id="blah" src="#" alt="your image" />
</form>
Javascript:
function readURL(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#blah').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
$("#imgInp").change(function(){
readURL(this);
});
I had the same problem for a bit. I noticed that I had:
Data Source= (localdb)\v11.0"
Simply by adding one back-slash it solved the problem for me:
Data Source= (localdb)\\v11.0"
I found the best way to do this is with ChronoUnit.
long minutes = ChronoUnit.MINUTES.between(fromDate, toDate);
long hours = ChronoUnit.HOURS.between(fromDate, toDate);

As we can see the raw method is slower the buffered.
you never set d[a]
to any value.
Because of this, d[a]
evaluates to undefined
, and you can't set properties on undefined
.
If you add d[a] = {}
right after d = {}
things should work as expected.
Alternatively, you could use an object initializer:
d[a] = {
greetings: b,
data: c
};
Or you could set all the properties of d
in an anonymous function instance:
d = new function () {
this[a] = {
greetings: b,
data: c
};
};
If you're in an environment that supports ES2015 features, you can use computed property names:
d = {
[a]: {
greetings: b,
data: c
}
};
If X
does NOT have a value, it will be assigned the value of Y
. Else, it will preserve it's original value, 5 in this example:
irb(main):020:0> x = 5
=> 5
irb(main):021:0> y = 10
=> 10
irb(main):022:0> x ||= y
=> 5
# Now set x to nil.
irb(main):025:0> x = nil
=> nil
irb(main):026:0> x ||= y
=> 10

I would recommend having a look at the plyr
package.
It might not be as fast as data.table or other packages, but it is quite instructive, especially when starting with R and having to do some data manipulation.
> DF <- data.frame(A = c("1", "1", "2", "3", "3"), B = c(2, 3, 3, 5, 6))
> library(plyr)
> DF.sum <- ddply(DF, c("A"), summarize, B = sum(B))
> DF.sum

Remove the definitions and check if the conditional is on debug mode. You do not need to check if the directive is on release mode.
Something like this:
#if DEBUG
Console.WriteLine("Mode=Debug");
#else
Console.WriteLine("Mode=Release");
#endif
This looks OK for SQL Server 2008. For SS2005 & earlier, you need to repeat the VALUES statement.
INSERT INTO dbo.MyTable (ID, Name)
VALUES (123, 'Timmy')
VALUES (124, 'Jonny')
VALUES (125, 'Sally')
EDIT:: My bad. You have to repeat the 'INSERT INTO' for each row in SS2005.
INSERT INTO dbo.MyTable (ID, Name)
VALUES (123, 'Timmy')
INSERT INTO dbo.MyTable (ID, Name)
VALUES (124, 'Jonny')
INSERT INTO dbo.MyTable (ID, Name)
VALUES (125, 'Sally')
Simply add this to your java module's build.gradle. It will include dependent libraries in archive.
mainClassName = "com.company.application.Main"
jar {
manifest {
attributes "Main-Class": "$mainClassName"
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
This will result in [module_name]/build/libs/[module_name].jar file.
Adding nan to list, and the below works for me:
some_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456',np.nan]
any([i for i in [x for x in some_list if str(x) != 'nan'] if "abc" in i])
You can't cast an IEnumerable<T> to a List<T>.
But you can accomplish this using LINQ:
var result = ((IEnumerable)myObject).Cast<object>().ToList();
My synopsis of rfc2397 is:
Once you've got your base64 encoded image data put it inside the <Image></Image> tags prefixed with "data:{mimetype};base64,
" this is similar to the prefixing done in the parenthesis of url()
definition in CSS or in the quoted value of the src
attribute of the img
tag in [X]HTML. You can test the data url in firefox by putting the data:image/...
line into the URL field and pressing enter, it should show your image.
For actually encoding I think we need to go over all your options, not just PHP, because there's so many ways to base64 encode something.
base64
command line tool. It's part of the GNU coreutils (v6+) and pretty much default in any Cygwin, Linux, GnuWin32 install, but not the BSDs I tried. Issue: $ base64 imagefile.ico > imagefile.base64.txt
A note on mime-types:
I would prefer you use one of image/png
image/jpeg
or image/gif
as I can't find the popular image/x-icon
. Should that be image/vnd.microsoft.icon
?
Also the other formats are much shorter.

Just wanted to give a vb.net (as with c language if want to convert..) I was having similar problem for uninstal of one of my programs, dropping the DB was bit tricky, yes could get users to go into server drop it using Express, but thats not clean, after few looks around got a perfect little bit of code together...
Sub DropMyDatabase()
Dim Your_DB_To_Drop_Name As String = "YourDB"
Dim Your_Connection_String_Here As String = "SERVER=MyServer;Integrated Security=True"
Dim Conn As SqlConnection = New SqlConnection(Your_Connection_String_Here)
Dim AlterStr As String = "ALTER DATABASE " & Your_DB_To_Drop_Name & " SET OFFLINE WITH ROLLBACK IMMEDIATE"
Dim AlterCmd = New SqlCommand(AlterStr, Conn)
Dim DropStr As String = "DROP DATABASE " & Your_DB_To_Drop_Name
Dim DropCmd = New SqlCommand(DropStr, Conn)
Try
Conn.Open()
AlterCmd.ExecuteNonQuery()
DropCmd.ExecuteNonQuery()
Conn.Close()
Catch ex As Exception
If (Conn.State = ConnectionState.Open) Then
Conn.Close()
End If
MsgBox("Failed... Sorry!" & vbCrLf & vbCrLf & ex.Message)
End Try
End Sub
Hope this helps anyone looking xChickenx
UPDATE Using this converter here is the C# version :
public void DropMyDatabase()
{
var Your_DB_To_Drop_Name = "YourDB";
var Your_Connection_String_Here = "SERVER=MyServer;Integrated Security=True";
var Conn = new SqlConnection(Your_Connection_String_Here);
var AlterStr = "ALTER DATABASE " + Your_DB_To_Drop_Name + " SET OFFLINE WITH ROLLBACK IMMEDIATE";
var AlterCmd = new SqlCommand(AlterStr, Conn);
var DropStr = "DROP DATABASE " + Your_DB_To_Drop_Name;
var DropCmd = new SqlCommand(DropStr, Conn);
try
{
Conn.Open();
AlterCmd.ExecuteNonQuery();
DropCmd.ExecuteNonQuery();
Conn.Close();
}
catch(Exception ex)
{
if((Conn.State == ConnectionState.Open))
{
Conn.Close();
}
Trace.WriteLine("Failed... Sorry!" + Environment.NewLine + ex.Message);
}
}
I would also trim the input field, cause a space could make it look like filled
if ($.trim($('#person_data[document_type]').val()) != '')
{
}
Or ast.literal_eval
(this is safe, unlike eval
):
ast.literal_eval("0xffff")
Demo:
>>> import ast
>>> ast.literal_eval("0xffff")

Had the same issue with module not found. Turns out I had a component
import Picture from './Picture/Picture';
at the very bottom of all the imports. When I moved it below import React, { Component } from 'react';
, it worked.
AppCompat v21 builds themes that require the new APIs provided in API 21 (Android 5.0). To compile your application with AppCompat, you must also compile against API 21. The recommended setup for compiling/building with API 21 is a compileSdkVersion
of 21
and a buildToolsVersion
of 21.0.1
(which is the highest at this time - you always want to use the latest build tools).
It failed because you used ajax="false"
. This fires a full synchronous request which in turn causes a full page reload, causing the oncomplete
to be never fired (note that all other ajax-related attributes like process
, onstart
, onsuccess
, onerror
and update
are also never fired).
That it worked when you removed actionListener
is also impossible. It should have failed the same way. Perhaps you also removed ajax="false"
along it without actually understanding what you were doing. Removing ajax="false"
should indeed achieve the desired requirement.
Also is it possible to execute actionlistener and oncomplete simultaneously?
No. The script can only be fired before or after the action listener. You can use onclick
to fire the script at the moment of the click. You can use onstart
to fire the script at the moment the ajax request is about to be sent. But they will never exactly simultaneously be fired. The sequence is as follows:
onclick
JavaScript code is executedprocess
and current HTML DOM treeonstart
JavaScript code is executedprocess
actionListener
JSF backing bean method is executedaction
JSF backing bean method is executedupdate
and current JSF component treeonsuccess
JavaScript code is executedonerror
JavaScript code is executedupdate
based on ajax response and current HTML DOM treeoncomplete
JavaScript code is executedNote that the update
is performed after actionListener
, so if you were using onclick
or onstart
to show the dialog, then it may still show old content instead of updated content, which is poor for user experience. You'd then better use oncomplete
instead to show the dialog. Also note that you'd better use action
instead of actionListener
when you intend to execute a business action.
range()
and xrange()
take a third parameter that specifies a step. So you can do the following.
range(10, 0, -1)
Which gives
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
But for iteration, you should really be using xrange
instead. So,
xrange(10, 0, -1)
Note for Python 3 users: There are no separate
range
andxrange
functions in Python 3, there is justrange
, which follows the design of Python 2'sxrange
.
const arr= [1, 2, 3]
arr.forEach(function(element){
if(arr[arr.length-1] === element){
console.log("Last Element")
}
})
Using DatabaseUtils.queryNumEntries()
:
public long getProfilesCount() {
SQLiteDatabase db = this.getReadableDatabase();
long count = DatabaseUtils.queryNumEntries(db, TABLE_NAME);
db.close();
return count;
}
or (more inefficiently)
public int getProfilesCount() {
String countQuery = "SELECT * FROM " + TABLE_NAME;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(countQuery, null);
int count = cursor.getCount();
cursor.close();
return count;
}
In Activity:
int profile_counts = db.getProfilesCount();
db.close();
Yes if you are using Python 3.3+. You can use the built-in unittest.mock
to assert method called. For Python 2.6+ use the rolling backport Mock
, which is the same thing.
Here is a quick example in your case:
from unittest.mock import MagicMock
aw = aps.Request("nv1")
aw.Clear = MagicMock()
aw2 = aps.Request("nv2", aw)
assert aw.Clear.called
Unfortunately, it doesn't look like file_get_contents()
really offers that degree of control. The cURL extension is usually the first to come up, but I would highly recommend the PECL_HTTP extension (http://pecl.php.net/package/pecl_http) for very simple and straightforward HTTP requests. (it's much easier to work with than cURL)
I worked a little bit the method that Rawling posted here to find more than one line in the same file until the end. This is what worked for me:
foreach (var line in File.ReadLines(pathToFile))
{
if (line.Contains("CustomerEN") && current == null)
{
current = new List<string>();
current.Add(line);
}
else if (line.Contains("CustomerEN") && current != null)
{
current.Add(line);
}
}
string s = String.Join(",", current);
MessageBox.Show(s);
The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.
import numpy as np
names = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 , 0.5678 , 0.9123 ])
ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats
np.savetxt('test.txt', ab, fmt="%10s %10.3f")
Update: This example also works properly in Python 3 by using the 'U6'
Unicode string dtype, when creating the ab
structured array, instead of the 'S6'
byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1'
in Python 3.
I am referring to these variables only from the C perspective.
From the perspective of the C language, all that matters is extent, scope, linkage, and access; exactly how items are mapped to different memory segments is up to the individual implementation, and that will vary. The language standard doesn't talk about memory segments at all. Most modern architectures act mostly the same way; block-scope variables and function arguments will be allocated from the stack, file-scope and static variables will be allocated from a data or code segment, dynamic memory will be allocated from a heap, some constant data will be stored in read-only segments, etc.
For a direct scroll:
getListView().setSelection(21);
For a smooth scroll:
getListView().smoothScrollToPosition(21);
You definitely need to map your servlet onto some URL. If you use Java EE 6 (that means at least Servlet API 3.0) then you can annotate your servlet like
@WebServlet(name="helloServlet", urlPatterns={"/hello"})
public class HelloWorld extends HttpServlet {
//rest of the class
Then you can just go to the localhost:8080/yourApp/hello
and the value should be displayed. In case you can't use Servlet 3.0 API than you need to register this servlet into web.xml
file like
<servlet>
<servlet-name>helloServlet</servlet-name>
<servlet-class>crunch.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>helloServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
I also think chart.Boxplot is the best option, it gives you the position of the mean but if you have a matrix with returns all you need is one line of code to get all the boxplots in one graph.

Box Plot of Return Matrix
chart.Boxplot(returnscc.z, names=T, horizontal=TRUE, colorset="darkgreen", as.Tufte =F,
mean.symbol = 20, median.symbol="|", main="Return Distributions Comparison",
element.color = "darkgray", outlier.symbol = 20,
xlab="Continuously Compounded Returns", sort.ascending=F)
You can try changing the mean.symbol, and remove or change the median.symbol. Hope it helped. :)
I have trouble wrapping my head around lambda expressions because I work in Visual FoxPro, which has Macro substitution and the ExecScript{} and Evaluate() functions, which seem to serve much the same purpose.
? Calculator(10, 23, "a + b")
? Calculator(10, 23, "a - b");
FUNCTION Calculator(a, b, op)
RETURN Evaluate(op)
One definite benefit to using formal lambdas is (I assume) compile-time checking: Fox won't know if you typo the text string above until it tries to run it.
This is also useful for data-driven code: you can store entire routines in memo fields in the database and then just evaluate them at run-time. This lets you tweak part of the application without actually having access to the source. (But that's another topic altogether.)
With JUnit 5 I was able to solve this using the @RepeatedTest annotation:
@RepeatedTest(10)
public void testMyCode() {
//your test code goes here
}
Note that @Test
annotation shouldn't be used along with @RepeatedTest
.
can't you just subset the columns in either df first?
[i for i in df.columns if i not in df2.columns]
dfNew = merge(df **[i for i in df.columns if i not in df2.columns]**, df2, left_index=True, right_index=True, how='outer')
You can push data from the server to the browser via Server Side Events. This is essentially a unidirectional stream that a client can "subscribe" to from a browser. From here, you could just create new Notification
objects as SSEs stream into the browser:
var source = new EventSource('/events');
source.on('message', message => {
var notification = new Notification(message.title, {
body: message.body
});
});
A bit old, but this article by Eric Bidelman explains the basics of SSE and provides some server code examples as well.
You could actually do this in a single malloc by allocating for the Vector and the array at the same time. Eg:
struct Vector y = (struct Vector*)malloc(sizeof(struct Vector) + 10*sizeof(double));
y->x = (double*)((char*)y + sizeof(struct Vector));
y->n = 10;
This allocates Vector 'y', then makes y->x point to the extra allocated data immediate after the Vector struct (but in the same memory block).
If resizing the vector is required, you should do it with the two allocations as recommended. The internal y->x array would then be able to be resized while keeping the vector struct 'y' intact.
Google Maps API v3:
I initialized Google Map and added markers to it. Later, I wanted to retrieve all markers and did it simply by accessing the map property "markers".
var map = new GMaps({
div: '#map',
lat: 40.730610,
lng: -73.935242,
});
var myMarkers = map.markers;
You can loop over it and access all Marker methods listed at Google Maps Reference.
You might have problem on Windows while adding jar to maven because of syntax.
Try encapsulating -D parameters with double quotas like this;
mvn install:install-file "-Dfile=ojdbc6.jar" "-DgroupId=com.oracle" "-DartifactId=ojdbc6" "-Dversion=11.2.0" "-Dpackaging=jar"
Be aware of you should use same version/atifactId/groupId inside your pom.xml. You can't use version 11.2.0.3 after command above. You have to put his in you pom.xml;
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
</dependency>
If you want to use another version, like 12.1.0.1, you should run above command with that version or other info

EDIT: Are you using canvas transforms? If so, you'll have to track the transformation matrix. The following method should measure the height of text with the initial transform.
EDIT #2: Oddly the code below does not produce correct answers when I run it on this StackOverflow page; it's entirely possible that the presence of some style rules could break this function.
The canvas uses fonts as defined by CSS, so in theory we can just add an appropriately styled chunk of text to the document and measure its height. I think this is significantly easier than rendering text and then checking pixel data and it should also respect ascenders and descenders. Check out the following:
var determineFontHeight = function(fontStyle) {
var body = document.getElementsByTagName("body")[0];
var dummy = document.createElement("div");
var dummyText = document.createTextNode("M");
dummy.appendChild(dummyText);
dummy.setAttribute("style", fontStyle);
body.appendChild(dummy);
var result = dummy.offsetHeight;
body.removeChild(dummy);
return result;
};
//A little test...
var exampleFamilies = ["Helvetica", "Verdana", "Times New Roman", "Courier New"];
var exampleSizes = [8, 10, 12, 16, 24, 36, 48, 96];
for(var i = 0; i < exampleFamilies.length; i++) {
var family = exampleFamilies[i];
for(var j = 0; j < exampleSizes.length; j++) {
var size = exampleSizes[j] + "pt";
var style = "font-family: " + family + "; font-size: " + size + ";";
var pixelHeight = determineFontHeight(style);
console.log(family + " " + size + " ==> " + pixelHeight + " pixels high.");
}
}
You'll have to make sure you get the font style correct on the DOM element that you measure the height of but that's pretty straightforward; really you should use something like
var canvas = /* ... */
var context = canvas.getContext("2d");
var canvasFont = " ... ";
var fontHeight = determineFontHeight("font: " + canvasFont + ";");
context.font = canvasFont;
/*
do your stuff with your font and its height here.
*/
Try using this for horizontal elements that won't center correctly.
width: calc (width: 100% - width whatever else is off centering it)
For example if your side navigation bar is 200px:
width: calc(100% - 200px);
you can do this:
<div class="picture1"> </div>
and put this into your css file:
div.picture1 {
width:100px; /*width of your image*/
height:100px; /*height of your image*/
background-image:url('yourimage.file');
margin:0; /* If you want no margin */
padding:0; /*if your want to padding */
}
otherwise, just use them as plain
One of the benefit of using the resource file is accessing the resources by names, so the image can change, the image name can change, as long as the resource is kept up to date correct image will show up.
Here is a cleaner approach to accomplish this: Assuming Resources.resx is in 'UI.Images' namespace, add the namespace reference in your xaml like this:
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:UI="clr-namespace:UI.Images"
Set your Image source like this:
<Image Source={Binding {x:Static UI:Resources.Search}} />
where 'Search' is name of the resource.
Meder Omuraliev suggested to use an event handler and set scrollTo(0,0). This is an example for Wassim-azirar. Bringing it all together, I assume this is the final solution.
We have 3 problems: the scrollbar, scrolling with mouse, and keyboard. This hides the scrollbar:
html, body{overflow:hidden;}
Unfortunally, you can still scroll with the keyboard: To prevent this, we can:
function keydownHandler(e) {
var evt = e ? e:event;
var keyCode = evt.keyCode;
if (keyCode==38 || keyCode==39 || keyCode==40 || keyCode==37){ //arrow keys
e.preventDefault()
scrollTo(0,0);
}
}
document.onkeydown=keydownHandler;
The scrolling with the mouse just naturally doesn't work after this code, so we have prevented the scrolling.
For example: https://jsfiddle.net/aL7pes70/1/
The first value is the precision and the second is the scale, so 18,0
is essentially 18 digits with 0 digits after the decimal place. If you had 18,2
for example, you would have 18 digits, two of which would come after the decimal...
example of 18,2: 1234567890123456.12
There is no functional difference between numeric
and decimal
, other that the name and I think I recall that numeric came first, as in an earlier version.
And to answer, "can I add (-10) in that column?" - Yes, you can.
You simply don't call the function.
>>>def x():
>>> print(20)
>>>y = x
>>>y()
20
The brackets tell python that you are calling the function, so when you put them there, it calls the function and assigns y
the value returned by x
(which in this case is None
).
How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?
You can undo changes to tracked files with:
git reset HEAD --hard
You can remove untracked files with:
git clean -f
You can remove untracked files and directories with:
git clean -fd
but you can't undo change to untracked files.
You can remove ignored and untracked files and directories
git clean -fdx
but you can't undo change to ignored files.
You can also set clean.requireForce
to false
:
git config --global --add clean.requireForce false
to avoid using -f
(--force
) when you use git clean
.
try getTimezoneOffset()
of the Date
object:
var curdate = new Date()
var offset = curdate.getTimezoneOffset()
This method returns time zone offset in minutes which is the difference between GMT and local time in minutes.
That is the class name and System.identityHashCode() separated by the '@' character. What the identity hash code represents is implementation-specific. It often is the initial memory address of the object, but the object can be moved in memory by the VM over time. So (briefly) you can't rely on it being anything.
Getting the memory addresses of variables is meaningless within Java, since the JVM is at liberty to implement objects and move them as it seems fit (your objects may/will move around during garbage collection etc.)
Integer.toBinaryString() will give you an integer in binary form.
For 3.x version
$( '.modal' ).modal( 'hide' ).data( 'bs.modal', null );
For 2.x version (risky; read comments below) When you create bootstrap modal three elements on your page being changed. So if you want to completely rollback all changes, you have to do it manually for each of it.
$( '.modal' ).remove();
$( '.modal-backdrop' ).remove();
$( 'body' ).removeClass( "modal-open" );
write() only takes a single string argument, so you could do this:
outf.write(str(num))
or
outf.write('{}'.format(num)) # more "modern"
outf.write('%d' % num) # deprecated mostly
Also note that write
will not append a newline to your output so if you need it you'll have to supply it yourself.
Aside:
Using string formatting would give you more control over your output, so for instance you could write (both of these are equivalent):
num = 7
outf.write('{:03d}\n'.format(num))
num = 12
outf.write('%03d\n' % num)
to get three spaces, with leading zeros for your integer value followed by a newline:
007
012
format() will be around for a long while, so it's worth learning/knowing.
{{ data.0 }}
should work.
Let's say you wrote data.obj
django tries data.obj
and data.obj()
. If they don't work it tries data["obj"]
. In your case data[0]
can be written as {{ data.0 }}
. But I recommend you to pull data[0]
in the view and send it as separate variable.
With awk:
curl -sS http://the_repo/com/stackoverflow/the_artifact/maven-metadata.xml | grep latest | awk -F'<latest>' '{print $2}' | awk -F'</latest>' '{print $1}'
With sed:
curl -sS http://the_repo/com/stackoverflow/the_artifact/maven-metadata.xml | grep latest | sed 's:<latest>::' | sed 's:</latest>::'
It's generally considered a bad idea to ignore exceptions. Usually, if it's appropriate, you want to either notify the user of the issue (if they would care) or at the very least, log the exception, or print the stack trace to the console.
However, if that's truly not necessary (you're the one making the decision) then no, there's no other way to ignore an exception that forces you to catch it. The only revision, in that case, that I would suggest is explicitly listing the the class of the Exceptions you're ignoring, and some comment as to why you're ignoring them, rather than simply ignoring any exception, as you've done in your example.
This is the result from
library(scales)
show_col(hue_pal()(4))
show_col(hue_pal()(3))
I made this work in this way:
<button class="btn" ng-click='toggleClass($event)'>button one</button>
<button class="btn" ng-click='toggleClass($event)'>button two</button>
in your controller:
$scope.toggleClass = function (event) {
$(event.target).toggleClass('active');
}
if ($_SERVER['REQUEST_METHOD'] == 'POST')
is the correct way, you can send a post request without any post data.
In SQL without SELECT
you cannot result anything. Instead of IF-ELSE
block I prefer to use CASE
statement for this
SELECT CASE
WHEN EXISTS (SELECT 1
FROM tblGLUserAccess
WHERE GLUserName = 'xxxxxxxx') THEN 1
ELSE 2
END
I use this and it works right
@Id
@GeneratedValue(generator = "SEC_ODON", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "SEC_ODON", sequenceName = "SO.SEC_ODON",allocationSize=1)
@Column(name="ID_ODON", unique=true, nullable=false, precision=10, scale=0)
public Long getIdOdon() {
return this.idOdon;
}
Try df['quantity'] = df['quantity'] * -1
.
You can redirect by this method also:
return Yii::$app->response->redirect(['user/index', 'id' => 10]);
If you want to send the Header information immediately use with send().This method adds a Location header to the current response.
return Yii::$app->response->redirect(['user/index', 'id' => 10])->send();
If you want the complete URL then use like Url::to(['user/index', 'id' => 302])
with the header of use yii\helpers\Url;
.

Just adding on to carlpett's answer. For a much useful view of the files, you could pipe the output to ls.
find . -maxdepth 1 -type f|ls -lt|less
Shows the most recently modified files in a list format, quite useful when you have downloaded a lot of files, and want to see a non-cluttered version of the recent ones.
Your formula is wrong. You probably meant something like:
=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")
Another equivalent:
=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")
Or even shorter:
=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))
OR EVEN SHORTER:
=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))
It may be worth considering if having your menu without any associated scope is the right way to go. Its not really the angular way.
But, if it is the way you need to go, then you can do it by adding the functions to $rootScope and then within those functions using $broadcast to send events. your controller then uses $on to listen for those events.
Another thing to consider if you do end up having your menu without a scope is that if you have multiple routes, then all of your controllers will have to have their own upate and get functions. (this is assuming you have multiple controllers)
Here is code to set default radio button set to true
@Html.RadioButtonFor(m => m.Gender, "Male", new { @checked = "checked", id = "rdGender", name = "rbGender" })
If you have proportioned elements, you could use:
.valid {
background-position: 98% center;
}
.half .valid {
background-position: 96% center;
}
In this example, .valid
would be the class with the picture and .half
would be a row with half the size of the standard one.
Dirty, but works as a charm and it's reasonably manageable.
i was getting an error saying Permission Denied after running any 'ng' command (ng --version). I googled for a while and tried clearing npm cache npm cache verify
, uninstalling my global angular cli (npm uninstall -g @angular/cli
) and reinstalling Angular/cli (npm install -g @angular/cli
) etc.. but it would give an error say its already installed. but the node_modules folder here wouldn't have any angular folder.. reinstalled node even then restarted my computer.
ANSWER: Finally I found that the ng.cmd and ng.ps1 files in C:\Users\JaGoodwin\AppData\Roaming\npm\
here were still there (in npm folder).. even though I did npm uninstall -g @angular/cli
. those files were causing ng (angular/cli) to think it was still installed. i deleted those files then npm install -g @angular/[email protected]
(version i need) I then removed my projects node_modules and then ran npm install
and now can run my angular project using ng serve
.
C:\Users\JaGoodwin\AppData\Roaming\npm\
Find this by folder searching %APPDATA% in your windows search bar.
I tried changing value="true"
to ng-value="true"
, and it seems to work.
<input type="radio" name="response2" data-ng-model="choice.isUserAnswer" ng-value="true" />
Also, to get both inputs to work in your example, you'd have to give different name to each input -- e.g. response
should become response1
and response2
.
I had a similar error but with different context when I uploaded a *.p file to Google Drive. I tried to use it later in a Google Colab session, and got this error:
1 with open("/tmp/train.p", mode='rb') as training_data:
----> 2 train = pickle.load(training_data)
UnpicklingError: invalid load key, '<'.
I solved it by compressing the file, upload it and then unzip on the session. It looks like the pickle file is not saved correctly when you upload/download it so it gets corrupted.

Yes there is. With .NET 3.5:
int sum = arr.Sum();
Console.WriteLine(sum);
If you're not using .NET 3.5 you could do this:
int sum = 0;
Array.ForEach(arr, delegate(int i) { sum += i; });
Console.WriteLine(sum);
And a UICollectionView
version, based on kolaworld's answer:
https://stackoverflow.com/a/43162226/1452758
Needs testing. Works so far on iOS 9.2, Xcode 9.2 beta 2, with scrolling a collectionView to an index, as a closure.
extension UICollectionView
{
/// Calls reloadsData() on self, and ensures that the given closure is
/// called after reloadData() has been completed.
///
/// Discussion: reloadData() appears to be asynchronous. i.e. the
/// reloading actually happens during the next layout pass. So, doing
/// things like scrolling the collectionView immediately after a
/// call to reloadData() can cause trouble.

/// This method uses CATransaction to schedule the closure.
func reloadDataThenPerform(_ closure: @escaping (() -> Void))
{
CATransaction.begin()
CATransaction.setCompletionBlock(closure)
self.reloadData()
CATransaction.commit()
}
}
Usage:
myCollectionView.reloadDataThenPerform {
myCollectionView.scrollToItem(at: indexPath,
at: .centeredVertically,
animated: true)

Relying on column order is generally a bad idea in SQL. SQL is based on Relational theory where order is never guaranteed - by design. You should treat all your columns and rows as having no order and then change your queries to provide the correct results:
For Columns:
For Rows:
Hope this helps...
if all you're trying to do is get the value of a single entry in a map, there's no need to loop over any collection at all. simplifying gautum's response slightly, you can get the value of a named map entry as follows:
<c:out value="${map['key']}"/>
where 'map' is the collection and 'key' is the string key for which you're trying to extract the value.
You can use any one of the below methods
If you are using java.text.DecimalFormat
DecimalFormat decimalFormat = NumberFormat.getCurrencyInstance();
decimalFormat.setMinimumFractionDigits(2);
System.out.println(decimalFormat.format(4.0));
OR
DecimalFormat decimalFormat = new DecimalFormat("#0.00");
System.out.println(decimalFormat.format(4.0));
If you want to convert it into simple string format
System.out.println(String.format("%.2f", 4.0));
All the above code will print 4.00

Thanks for all your help! Using all your clues, I've written routine to do exactly what I want -- python-like string formatting using dictionary. Since I'm Java newbie, any hints are appreciated.
public static String dictFormat(String format, Hashtable<String, Object> values) {
StringBuilder convFormat = new StringBuilder(format);
Enumeration<String> keys = values.keys();
ArrayList valueList = new ArrayList();
int currentPos = 1;
while (keys.hasMoreElements()) {
String key = keys.nextElement(),
formatKey = "%(" + key + ")",
formatPos = "%" + Integer.toString(currentPos) + "$";
int index = -1;
while ((index = convFormat.indexOf(formatKey, index)) != -1) {
convFormat.replace(index, index + formatKey.length(), formatPos);
index += formatPos.length();
}
valueList.add(values.get(key));
++currentPos;
}
return String.format(convFormat.toString(), valueList.toArray());
}
ListBuffer
is a mutable list which has constant-time append, and constant-time conversion into a List
.
List
is immutable and has constant-time prepend and linear-time append.
How you construct your list depends on the algorithm you'll use the list for and the order in which you get the elements to create it.
For instance, if you get the elements in the opposite order of when they are going to be used, then you can just use a List
and do prepends. Whether you'll do so with a tail-recursive function, foldLeft
, or something else is not really relevant.
If you get the elements in the same order you use them, then a ListBuffer
is most likely a preferable choice, if performance is critical.
But, if you are not on a critical path and the input is low enough, you can always reverse
the list later, or just foldRight
, or reverse
the input, which is linear-time.
What you DON'T do is use a List
and append to it. This will give you much worse performance than just prepending and reversing at the end.
In my case..

I changed the 'Untitlted Folder' name by going upward one directory where the untitled folder and other docs are listed.
Tick the little white box in front of the 'Untitled Folder', a 'rename' button will show up at the top. Then click and change the folder name into whatever kinky name you want.
See the 'Rename' button?
I've fixed this…by simply opening a new tab.
Why it wasn't working I'm not entirely sure, but it could have something to do with how Chrome deals with multiple downloads on a page, perhaps it thought they were spam and just ignored them.
You could create a new repo with
git init
and then use
git fetch url-to-repo branchname:refs/remotes/origin/branchname
to fetch just that one branch into a local remote-tracking branch.
Because &
has a lesser priority than ==
.
Your code is equivalent to a[0] & (1 == 0)
, and unless a[0]
is a boolean this won't compile...
You need to:
(a[0] & 1) == 0
etc etc.
(yes, Java does hava a boolean &
operator -- a non shortcut logical and)
For repeating an action in the future, there is the built in setInterval
function that you can use instead of setTimeout
.
It has a similar signature, so the transition from one to another is simple:
setInterval(function() {
// do stuff
}, duration);
Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.
DIR="$( cd "$( dirname "$0" )" && pwd )"
By switching directories in a subshell, we can then call pwd
and get the correct path of the script regardless of context.
You can then use $DIR
as "$DIR/path/to/file"
Simplified, non-technical explanation: A web serivce allows a PROGRAM to talk to a web page, instead of using your browser to open a web page.
Example: I can go to maps.google.com, and type in my home address, and see a map of where I live in my browser.
But what if you were writing a computer program where you wanted to take an address and show a pretty map, just like Google maps?
Well, you could write a whole new mapping program from scratch, OR you could call a web service that Google maps provides, send it the address, and it will return a graphical map of the location, which you can display in your program.
There is a lot more to it, as some of the other posts go into, but the upshot is that it allows your application to either retrieve information FROM, or submit information TO some resource. Some other examples:
Use the modulus (%
) operator:
6 % 3 == 0
7 % 3 == 1
public Form1()
{
InitializeComponent();
//this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
this.MaximizeBox = false;
this.MinimizeBox = false;
}
The fastest solution if you are not embedding js into your template is:
Put <script type="text/javascript"> window.CSRF_TOKEN = "{{ csrf_token }}"; </script>
before your reference to script.js file in your template, then add csrfmiddlewaretoken
into your data
dictionary:
$.ajax({
type: 'POST',
url: somepathname + "do_it/",
data: {csrfmiddlewaretoken: window.CSRF_TOKEN},
success: function() {
console.log("Success!");
}
})
If you do embed your js into the template, it's as simple as: data: {csrfmiddlewaretoken: '{{ csrf_token }}'}
The toString()
method returns a textual representation of an object. A basic implementation is already included in java.lang.Object
and so because all objects inherit from java.lang.Object
it is guaranteed that every object in Java has this method.
Overriding the method is always a good idea, especially when it comes to debugging, because debuggers often show objects by the result of the toString()
method. So use a meaningful implementation but use it for technical purposes. The application logic should use getters:
public class Contact {
private String firstName;
private String lastName;
public Contact (String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
public String getFirstName() {return firstName;}
public String getLastName() {return lastName;}
public String getContact() {
return firstName + " " + lastName;
}
@Override
public String toString() {
return "["+getContact()+"]";
}
}
In old vi, b
moves the cursor to the beginning of the word before cursor, w
moves the cursor to the beginning of the word after cursor, e
moves cursor at the end of the word after cursor and dw
deletes from the cursor to the end of the word.
If you type wbdw
, you delete the word around cursor, even if the cursor is at the beginning or at the end of the word. Note that whitespaces after a word are considerer to be part of the word to be deleted.
Simply do this
var key = "keyOne";
var obj = {};
obj[key] = someValue;
One more thing to check: if you've set up HTTPS access before setting up PHP -- I used certbot -- you'll need to make the changes in /etc/nginx/sites-available/default twice because there will be two server blocks (one listening on port 80 and one listening on port 443).
(I was setting up this server primarily for email and didn't have any use for PHP when I first installed nginx just as a way to run certbot more easily.)
We can find hive version by
above cmds works on hive 0.13 and above.
Set system:sun.java.command;
gives the hive version from hue hive editor it gives the the jar name which includes the version.
It is CMD + P (or CTRL + P) by default. However the keyboard bindings may differ according to your preferences.
To know your bindings go to the "Keyboard Shortcuts" settings and search for "Go to File"
Escaping parameters like that is usually source of frustration and feels a lot like a time wasted. I see you're on v2 so I would suggest using a technique that Joel "Jaykul" Bennet blogged about a while ago.
Long story short: you just wrap your string with @' ... '@ :
Start-Process \\server\toto.exe @'
-batch=B -param="sort1;parmtxt='Security ID=1234'"
'@
(Mind that I assumed which quotes are needed, and which things you were attempting to escape.) If you want to work with the output, you may want to add the -NoNewWindow
switch.
BTW: this was so important issue that since v3 you can use --%
to stop the PowerShell parser from doing anything with your parameters:
\\server\toto.exe --% -batch=b -param="sort1;paramtxt='Security ID=1234'"
... should work fine there (with the same assumption).

Send params from View to an other View, from Sender View to Receiver View use viewParam and includeViewParams=true
In Sender
Sender.xhtml
<f:metadata>
<f:viewParam name="ID" value="#{senderMB._strID}" />
</f:metadata>
“includeViewParams=true”
in return String of click button event
Click button fire senderMB.clickBtnDetail(dto) with dto from senderMB._arrDataSender.xhtml
<p:dataTable rowIndexVar="index" id="dataTale"value="#{senderMB._arrData}" var="dto">
<p:commandButton action="#{senderMB.clickBtnDetail(dto)}" value="??"
ajax="false"/>
</p:dataTable>
In senderMB.clickBtnDetail(dto) we assign _strID with argument we got from button event (dto), here this is Sender_DTO and assign to senderMB._strID
Sender_MB.java
public String clickBtnDetail(sender_DTO sender_dto) {
this._strID = sender_dto.getStrID();
return "Receiver?faces-redirect=true&includeViewParams=true";
}
The link when clicked will become http://localhost:8080/my_project/view/Receiver.xhtml?*ID=12345*
In Recever
Receiver.xhtml
<f:metadata><f:viewParam name="ID" value="#{receiver_MB._strID}"/></f:metadata>
It will get param ID from sender View and assign to receiver_MB._strID
Receiver.xhtml
<f:event listener="#{receiver_MB.preRenderView}" type="preRenderView" />
into f:metadata tag
Receiver.xhtml
<f:metadata>
<f:viewParam name="ID" value="#{receiver_MB._strID}" />
<f:event listener="#{receiver_MB.preRenderView}"
type="preRenderView" />
</f:metadata>
Now we want to use this param in our read database method, it is available to use
Receiver_MB.java
public void preRenderView(ComponentSystemEvent event) throws Exception {
if (FacesContext.getCurrentInstance().isPostback()) {
return;
}
readFromDatabase();
}
private void readFromDatabase() {
//use _strID to read and set property
}
Not All Components.
the state
in component looks like the source of the waterfall of state of the whole APP.
So the change happens from where the setState called. The tree of renders
then get called from there. If you've used pure component, the render
will be skipped.

__func__
is an implicitly declared identifier that expands to a character array variable containing the function name when it is used inside of a function. It was added to C in C99. From C99 §6.4.2.2/1:
The identifier
__func__
is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declarationstatic const char __func__[] = "function-name";
appeared, where function-name is the name of the lexically-enclosing function. This name is the unadorned name of the function.
Note that it is not a macro and it has no special meaning during preprocessing.
__func__
was added to C++ in C++11, where it is specified as containing "an implementation-de?ned string" (C++11 §8.4.1[dcl.fct.def.general]/8), which is not quite as useful as the specification in C. (The original proposal to add __func__
to C++ was N1642).
__FUNCTION__
is a pre-standard extension that some C compilers support (including gcc and Visual C++); in general, you should use __func__
where it is supported and only use __FUNCTION__
if you are using a compiler that does not support it (for example, Visual C++, which does not support C99 and does not yet support all of C++0x, does not provide __func__
).
__PRETTY_FUNCTION__
is a gcc extension that is mostly the same as __FUNCTION__
, except that for C++ functions it contains the "pretty" name of the function including the signature of the function. Visual C++ has a similar (but not quite identical) extension, __FUNCSIG__
.
For the nonstandard macros, you will want to consult your compiler's documentation. The Visual C++ extensions are included in the MSDN documentation of the C++ compiler's "Predefined Macros". The gcc documentation extensions are described in the gcc documentation page "Function Names as Strings."
sessionStorage
is the same as localStorage
, except that it stores the data for only one session, and it will be removed when the user closes the browser window that created it.
The problem is because you haven't set JAVA_HOME in Mac properly. In order to do that, you should do set it like this:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
In my case my JDK installation is jdk1.8.0_40, make sure you type yours.
Then you can use maven commands.

Create a button with an id share and add the following code snippet.
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "Your body here";
String shareSub = "Your subject here";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, shareSub);
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share using"));
}
});
The above code snippet will open the share chooser on share button click action. However, note...The share code snippet might not output very good results using emulator. For actual results, run the code snippet on android device to get the real results.

You should use git pull --rebase
when
Indeed -- why not then? It's more clear, and doesn't impose a logical grouping on your commits.
Ok, I suppose it needs some clarification. In Git, as you probably know, you're encouraged to branch and merge. Your local branch, into which you pull changes, and remote branch are, actually, different branches, and git pull
is about merging them. It's reasonable, since you push not very often and usually accumulate a number of changes before they constitute a completed feature.
However, sometimes--by whatever reason--you think that it would actually be better if these two--remote and local--were one branch. Like in SVN. It is here where git pull --rebase
comes into play. You no longer merge--you actually commit on top of the remote branch. That's what it actually is about.
Whether it's dangerous or not is the question of whether you are treating local and remote branch as one inseparable thing. Sometimes it's reasonable (when your changes are small, or if you're at the beginning of a robust development, when important changes are brought in by small commits). Sometimes it's not (when you'd normally create another branch, but you were too lazy to do that). But that's a different question.
If you scale 1600x900
to 1280x720
you have
scale_x = 1280.0/1600
scale_y = 720.0/900
Then you can use it to find button size, and button position
button_width = 300 * scale_x
button_height = 300 * scale_y
button_x = 1440 * scale_x
button_y = 860 * scale_y
If you scale 1280x720
to 1600x900
you have
scale_x = 1600.0/1280
scale_y = 900.0/720
and rest is the same.
I add .0
to value to make float
- otherwise scale_x
, scale_y
will be rounded to integer
- in this example to 0

Assuming that you are using UTF-8 encoding:
string convert = "This is the string to be converted";

byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);
// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);
I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..
1. onBindViewHolder() methods never got called. --> Problem 1.
2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.
Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.
Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it.
To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager
and paste the code below into it. NO CHANGES REQUIRED
public class CustomLinearLayoutManager extends LinearLayoutManager {
private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();
public CustomLinearLayoutManager(Context context) {
super(context);
}
public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super(context, orientation, reverseLayout);
}

If you're using PHP you can funnel your request to Node scripts via shell_exec, passing arguments to scripts as JSON strings in the command line. Example call:
<?php
shell_exec("node nodeScript.js"); // without arguments
shell_exec("node nodeScript.js '{[your JSON here]}'"); //with arguments
?>
The caveat is you need to be very careful about handling user data when it goes anywhere near a command line. Example nightmare:
<?php
$evilUserData = "'; [malicious commands here];";
shell_exec("node nodeScript.js '{$evilUserData}'");
?>
You want to do the check for undefined
first. If you do it the other way round, it will generate an error if the array is undefined.
if (array === undefined || array.length == 0) {
// array empty or does not exist
}
This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null
values, other types of objects with a length
property, etc. It is also not very idiomatic JavaScript.
The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length
property.
if (!Array.isArray(array) || !array.length) {
// array does not exist, is not an array, or is empty
// ? do not attempt to process array
}
To break it down:
Array.isArray()
, unsurprisingly, checks whether its argument is an array. This weeds out values like null
, undefined
and anything else that is not an array.
Note that this will also eliminate array-like objects, such as the arguments
object and DOM NodeList
objects. Depending on your situation, this might not be the behavior you're after.
The array.length
condition checks whether the variable's length
property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0
or array.length !== 0
are not required here.
The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.
In those cases, I tend to go for the following, more idiomatic JavaScript:
if (!array || !array.length) {
// array or array.length are falsy
// ? do not attempt to process array
}
Or, more frequently, its inverse:
if (array && array.length) {
// array and array.length are truthy
// ? probably OK to process array
}
With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:
if (!array?.length) {
// array or array.length are falsy
// ? do not attempt to process array
}
Or the opposite:
if (array?.length) {
// array and array.length are truthy
// ? probably OK to process array
}

img = Image.open("picture.jpg")
Img.show
Make sure the name of the image is in parantheses this should work
If the position of the element containing the Lorum Ipsum is set absolute, you can specify the position via CSS. The "here" and "and here" elements would need to be contained in a block level element. I'll use markup like this.
print("<div id="lipsum">");
print("<div id="here">");
print(" here");
print("</div>");
print("<div id="andhere">");
print("and here");
print("</div>");
print("blah");
print("</div>");
Here's the CSS for above.
#lipsum {position:absolute;top:0;left:0;} /* example */ #here {position:absolute;top:0;right:0;} #andhere {position:absolute;bottom:0;right:0;}
Again, the above only works (reliably) if #lipsum is positioned via absolute.
If not, you'll need to use the float property.
#here, #andhere {float:right;}
You'll also need to put your markup in the appropriate place. For better presentation, your two divs will probably need some padding and margins so that the text doesn't all run together.
Use like blow
$(function (a) {
. . . . .then in your function you can using msie property like
if (a.browser.msie)
{
}
else
{
$(settings.current).after(Uploadelement);
}

I agree with Joachim that you should replace the hyphen with NULL
. But, if you really do want a hyphen, convert the date to a string:
(CASE WHEN B.[STAT] IS NULL

ELSE '-'
END) AS [DATE]

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:
pause
to the batch file so that you can see what is happening before it exits.
.bat
files and select "edit". This will open the file in notepad.pause
.- OR -
.bat
files are located, hold down the "shift" key and right click in the white space.Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.
Here is another FastRGB implementation found here:
public class FastRGB {
public int width;
public int height;
private boolean hasAlphaChannel;
private int pixelLength;
private byte[] pixels;
FastRGB(BufferedImage image) {
pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
width = image.getWidth();
height = image.getHeight();
hasAlphaChannel = image.getAlphaRaster() != null;
pixelLength = 3;
if (hasAlphaChannel)
pixelLength = 4;
}
short[] getRGB(int x, int y) {
int pos = (y * pixelLength * width) + (x * pixelLength);
short rgb[] = new short[4];
if (hasAlphaChannel)
rgb[3] = (short) (pixels[pos++] & 0xFF); // Alpha
rgb[2] = (short) (pixels[pos++] & 0xFF); // Blue
rgb[1] = (short) (pixels[pos++] & 0xFF); // Green
rgb[0] = (short) (pixels[pos++] & 0xFF); // Red
return rgb;
}
}
What is this?
Reading an image pixel by pixel through BufferedImage's getRGB method is quite slow, this class is the solution for this.
The idea is that you construct the object by feeding it a BufferedImage instance, and it reads all the data at once and stores them in an array. Once you want to get pixels, you call getRGB
Dependencies
import java.awt.image.BufferedImage;
import java.awt.image.DataBufferByte;
Considerations
Although FastRGB makes reading pixels much faster, it could lead to high memory usage, as it simply stores a copy of the image. So if you have a 4MB BufferedImage in the memory, once you create the FastRGB instance, the memory usage would become 8MB. You can however, recycle the BufferedImage instance after you create the FastRGB.
Be careful to not fall into OutOfMemoryException when using it on devices such as Android phones, where RAM is a bottleneck
If your table columns contains duplicate data and If you directly apply row_ number() and create PARTITION on column, there is chance to have result in duplicated row and with row number value.
To remove duplicate row, you need one more INNER query in from clause which eliminates duplicate rows and then it will give output to it's foremost outer FROM clause where you can apply PARTITION and ROW_NUMBER ().
As like below example:
SELECT DATE, STATUS, TITLE, ROW_NUMBER() OVER (PARTITION BY DATE, STATUS, TITLE ORDER BY QUANTITY ASC) AS Row_Num
FROM (
SELECT DISTINCT <column names>...
) AS tbl
// This is for normal triangle
for (int i = 0; i < 5; i++)
{
for (int j = 5; j > i; j--)
{
System.out.print(" ");
}
for (int k = 1; k <= i + 1; k++) {
System.out.print(" *");
}
System.out.print("\n");
}
// This is for left triangle, just removed space before printing *
for (int i = 0; i < 5; i++)
{
for (int j = 5; j > i; j--)
{
System.out.print(" ");
}
for (int k = 1; k <= i + 1; k++) {
System.out.print("*");
}
System.out.print("\n");
}
This should do it
For large files:
filenames = ['file1.txt', 'file2.txt', ...]
with open('path/to/output/file', 'w') as outfile:
for fname in filenames:
with open(fname) as infile:
for line in infile:
outfile.write(line)
For small files:
filenames = ['file1.txt', 'file2.txt', ...]
with open('path/to/output/file', 'w') as outfile:
for fname in filenames:
with open(fname) as infile:
outfile.write(infile.read())
… and another interesting one that I thought of:
filenames = ['file1.txt', 'file2.txt', ...]
with open('path/to/output/file', 'w') as outfile:
for line in itertools.chain.from_iterable(itertools.imap(open, filnames)):
outfile.write(line)
Sadly, this last method leaves a few open file descriptors, which the GC should take care of anyway. I just thought it was interesting
You can also use this extension method to easily register a handler for item property change in relevant collections. This method is automatically added to all the collections implementing INotifyCollectionChanged that hold items that implement INotifyPropertyChanged:
public static class ObservableCollectionEx
{
public static void SetOnCollectionItemPropertyChanged<T>(this T _this, PropertyChangedEventHandler handler)
where T : INotifyCollectionChanged, ICollection<INotifyPropertyChanged>
{
_this.CollectionChanged += (sender,e)=> {
if (e.NewItems != null)
{
foreach (Object item in e.NewItems)
{
((INotifyPropertyChanged)item).PropertyChanged += handler;
}
}
if (e.OldItems != null)
{
foreach (Object item in e.OldItems)
{
((INotifyPropertyChanged)item).PropertyChanged -= handler;
}
}
};
}
}
How to use:
public class Test
{
public static void MyExtensionTest()
{
ObservableCollection<INotifyPropertyChanged> c = new ObservableCollection<INotifyPropertyChanged>();
c.SetOnCollectionItemPropertyChanged((item, e) =>
{
//whatever you want to do on item change
});
}
}
