To exit from an Android app, just simply use. in your Main Activity, or you can use Android manifest file to set
android:noHistory="true"
It is a bug in Firefox 3.5.
Have a look.. https://bugzilla.mozilla.org/show_bug.cgi?id=279048
@Override public void onBackPressed() {
Log.d("CDA", "onBackPressed Called");
Intent intent = new Intent();
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
}
suppose you have a button:
<button onclick="backBtn();">Back...</button>
Here the code of the backBtn method:
function backBtn(){
parent.history.back();
return false;
}
When u call finish onDestroy() of that activity will be called and it will go back to previous activity in the activity stack... So.. for exit do not call finish();
@Override
public void onBackPressed() {
// Put your code here.
}
//I had to go back to the dashboard. Hence,
@Override
public void onBackPressed() {
Intent intent = new Intent(this,Dashboard.class);
startActivity(intent);
}
Just write this above or below the onCreate Method(within the class)
I had the Same problem, I have one LoginActivity and one MainActivity. If I click back button in MainActivity, Application has to close. SO I did with OnBackPressed method. this moveTaskToBack() work as same as Home Button. It leaves the Back stack as it is.
public void onBackPressed() {
// super.onBackPressed();
moveTaskToBack(true);
}
You can use always stream writer.It will erase old data and append new one each time.
using (StreamWriter sw = new StreamWriter(filePath))
{
getNumberOfControls(frm1,sw);
}
I ran into this issue while building libgit2-0.23.4. For me the problem was that C++ compiler & related packages were not installed with VS2015, therefore "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" file was missing and Cmake wasn't able to find the compiler.
I tried manually creating a C++ project in the Visual Studio 2015 GUI (C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe) and while creating the project, I got a prompt to download the C++ & related packages.
After downloading required packages, I could see vcvarsall.bat & Cmake was able to find the compiler & executed successfully with following log:

There are a lot of examples online using ComputeHash(). My testing showed this was very slow when running over a network connection. The snippet below runs much faster for me, however your mileage may vary:
$md5 = [System.Security.Cryptography.MD5]::Create("MD5")
$fd = [System.IO.File]::OpenRead($file)
$buf = New-Object byte[] (1024*1024*8) # 8 MB buffer
while (($read_len = $fd.Read($buf,0,$buf.length)) -eq $buf.length){
$total += $buf.length
$md5.TransformBlock($buf,$offset,$buf.length,$buf,$offset)
Write-Progress -Activity "Hashing File" `
-Status $file -percentComplete ($total/$fd.length * 100)
}
# Finalize the last read
$md5.TransformFinalBlock($buf, 0, $read_len)
$hash = $md5.Hash
# Convert hash bytes to a hexadecimal formatted string
$hash | foreach { $hash_txt += $_.ToString("x2") }
Write-Host $hash_txt
Just use the following code in your javaScript:

USE THIS ONLY IF YOU HAVE LIMITED NUMBER OF ITEMS IN YOUR RECYCLER VIEW.
I tried using boolean value in model and keep the checkbox status, but it did not help in my case.
What worked for me is this.setIsRecyclable(false);
public class ComponentViewHolder extends RecyclerView.ViewHolder {
public MyViewHolder(View itemView) {
super(itemView);
....
this.setIsRecyclable(false);
}
More explanation on this can be found here https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder.html#isRecyclable()
NOTE: This is a workaround. To use it properly you can refer the document which states "Calls to setIsRecyclable() should always be paired (one call to setIsRecyclabe(false) should always be matched with a later call to setIsRecyclable(true)). Pairs of calls may be nested, as the state is internally reference-counted." I don't know how to do this in code, if someone can provide more code on this.
app.controller('NavCtrl', function ($scope, $location, $state, $window, Post, Auth) {
$scope.post = {url: 'http://', title: ''};
$scope.createVariable = function(url) {
$window.location.href = url;
};
$scope.createFixed = function() {
$window.location.href = '/tab/newpost';
};
});

tl;dr the "standards" are a hodge-podge mess; it depends who you ask!
Overall, there appears to be no MIME type image/jpg
. Yet, in practice, nearly all software handles image files named "*.jpg
" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg
could be many different things.
For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.
.jfif
, .jfif-tbnl
, .jpe
, .jpeg
, .jpg
? image/jpeg
.jfif
, .jpe
, .jpeg
, .jpg
? image/pjpeg
.jpeg
, .jpg
? image/jpeg
.jpeg
, .jpg
? image/x-citrix-jpeg
.pjpeg
? image/pjpeg
jpg
not mentionedjpeg
? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg
13JPEG
? video/JPEG
jpeg2000
? video/jpeg2000
jpm
? image/jpm
(JPEG 2000)jpx
? image/jpx
(JPEG 2000)vnd.sealedmedia.softseal.jpg
? image/vnd.sealedmedia.softseal.jpg
These "complete lists" and RFC do not have MIME type image/jpg
! But for MIME type image/jpeg
some lists do have varying file name extensions (.jpeg
, .jpg
, …). Other lists do not mention image/jpeg
.
Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.
Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf
is preferred file extension for image/jpx
but in IANA Media Types the name jpf
is not present (and that IANA document references RFC 3745!).
Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.
Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?
The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg
yet there exists the odd vnd.sealedmedia.softseal.jpg
. File extension.JPEG
is only known as a video
type while file extension .jpeg
is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000
is type video
yet RFC 3745 considers JPEG 2000 an image
type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg
).
Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

namespace std
{
// define std::byte
enum class byte : unsigned char {};
};
This if your C++ version does not have std::byte will define a byte type in namespace std. Normally you don't want to add things to std, but in this case it is a standard thing that is missing.
std::byte from the STL does much more operations.
The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, &&
and ||
only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{}
construction and to direct program control rather than construct new vectors.. The &
and the |
operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.
When the arguments to &&
or ||
are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.
> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3
The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.
In a nutshell answer.
You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:
#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);
You can also specify a code page, so if your std::string contains UTF-8 chars you can use:
CA2W pszWide(str.c_str(), CP_UTF8);
Very useful but Windows only.

Express version:
"dependencies": {
"body-parser": "^1.19.0",
"express": "^4.17.1"
}
Optional parameter are very much handy, you can declare and use them easily using express:
app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
console.log("category Id: "+req.params.cId);
console.log("product ID: "+req.params.pId);
if (req.params.batchNo){
console.log("Batch No: "+req.params.batchNo);
}
});
In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'
Now I can call with only categoryId and productId or with all three-parameter.

Just an update of James' answer.
Isn't this the normal way to free the memory associated with an object?
Yes. It is the normal way to free memory. But new/delete operator always leads to memory leak problem.
Since c++17 already removed auto_ptr auto_ptr. I suggest shared_ptr or unique_ptr to handle the memory problems.
void test()
{
std::shared_ptr<Object1> obj1(new Object1);
} // The object is automatically deleted when the scope ends or reference counting reduces to 0.

This is an extension to Pache's answer using Guava's ListenableFuture
.
In particular, Futures.transform()
returns ListenableFuture
so can be used to chain async calls. Futures.addCallback()
returns void
, so cannot be used for chaining, but is good for handling success/failure on an async completion.
// ListenableFuture1: Open Database
ListenableFuture<Database> database = service.submit(() -> openDatabase());
// ListenableFuture2: Query Database for Cursor rows
ListenableFuture<Cursor> cursor =
Futures.transform(database, database -> database.query(table, ...));
// ListenableFuture3: Convert Cursor rows to List<Foo>
ListenableFuture<List<Foo>> fooList =
Futures.transform(cursor, cursor -> cursorToFooList(cursor));
// Final Callback: Handle the success/errors when final future completes
Futures.addCallback(fooList, new FutureCallback<List<Foo>>() {
public void onSuccess(List<Foo> foos) {
doSomethingWith(foos);
}
public void onFailure(Throwable thrown) {
log.error(thrown);
}
});
NOTE: In addition to chaining async tasks, Futures.transform()
also allows you to schedule each task on a separate executor (Not shown in this example).
public class Person{
String s;
Date d;
...
public Person clone(){
Person p = new Person();
p.s = this.s.clone();
p.d = this.d.clone();
...
return p;
}
}
In your executing code:
ArrayList<Person> clone = new ArrayList<Person>();
for(Person p : originalList)
clone.add(p.clone());
I think it is too early to give a "best practices" answer for this as there hasn't been enough time to use it in practice. If this was asked about throw specifiers right after they came out then the answers would be very different to now.
Having to think about whether or not I need to append
noexcept
after every function declaration would greatly reduce programmer productivity (and frankly, would be a pain).
Well, then use it when it's obvious that the function will never throw.
When can I realistically expect to observe a performance improvement after using
noexcept
? [...] Personally, I care aboutnoexcept
because of the increased freedom provided to the compiler to safely apply certain kinds of optimizations.
It seems like the biggest optimization gains are from user optimizations, not compiler ones due to the possibility of checking noexcept
and overloading on it. Most compilers follow a no-penalty-if-you-don't-throw exception handling method, so I doubt it would change much (or anything) on the machine code level of your code, although perhaps reduce the binary size by removing the handling code.
Using noexcept
in the big four (constructors, assignment, not destructors as they're already noexcept
) will likely cause the best improvements as noexcept
checks are 'common' in template code such as in std
containers. For instance, std::vector
won't use your class's move unless it's marked noexcept
(or the compiler can deduce it otherwise).
Assuming your cursor sits at the beginning of the block:
V/^$<CR>d (where <CR> is the enter/return key)
V
/^$<CR>
d
A more robust solution:
:set nowrapscan
:nnoremap D V/^\s*$\\|\%$<CR>d
:set nowrapscan
D
key (to the following commands): :nnoremap D
V
/^\s*$\\|\%$<CR>
d
I would do it something like this as it gives you 3 even sized columns, even spacing and (even) scales. Note: This is not tested so it might need tweaking for older browsers.

You can define a Headers object with a dictionary of HTTP key/value pairs, and then pass it in as an argument to http.get()
and http.post()
like this:
const headerDict = {
'Content-Type': 'application/json',
'Accept': 'application/json',
'Access-Control-Allow-Headers': 'Content-Type',
}
const requestOptions = {
headers: new Headers(headerDict),
};
return this.http.get(this.heroesUrl, requestOptions)
Or, if it's a POST request:
const data = JSON.stringify(heroData);
return this.http.post(this.heroesUrl, data, requestOptions);
Since Angular 7 and up you have to use HttpHeaders
class instead of Headers
:
const requestOptions = {
headers: new HttpHeaders(headerDict),
};
in my case closing the visual studio code then starting the server did the trick
Operating system - ubuntu 16.4 lts

This sure sounds like the typical use of protoype-based objects:
// define a new type of object
var foo = function() {};
// define a default attribute and value that all objects of this type will have
foo.prototype.attribute1 = "defaultValue1";
// create a new object of my type
var emptyObj = new foo();
console.log(emptyObj.attribute1); // outputs defaultValue1
As many said:
String phoneNumber = TelephonyManager.getDefault().getLine1Number();
The availability depends strictly on the carrier and the way the number is encoded on the SIM card. If it is hardcoded by the company that makes the SIMs or by the mobile carrier itself. This returns the same as in Settings->about phone.
If 'bounds_changed' is not firing correctly (sometimes Google doesn't seem to accept coordinates perfectly), then consider using 'center_changed' instead.
The 'center_changed' event fires every time fitBounds() is called, although it runs immediately and not necessarily after the map has moved.
In normal cases, 'idle' is still the best event listener, but this may help a couple people running into weird issues with their fitBounds() calls.
Here is the actual VIM code that generates the swap file extensions:
/*
* Change the ".swp" extension to find another file that can be used.
* First decrement the last char: ".swo", ".swn", etc.
* If that still isn't enough decrement the last but one char: ".svz"
* Can happen when editing many "No Name" buffers.
*/
if (fname[n - 1] == 'a') /* ".s?a" */
{
if (fname[n - 2] == 'a') /* ".saa": tried enough, give up */
{
EMSG(_("E326: Too many swap files found"));
vim_free(fname);
fname = NULL;
break;
}
--fname[n - 2]; /* ".svz", ".suz", etc. */
fname[n - 1] = 'z' + 1;
}
--fname[n - 1]; /* ".swo", ".swn", etc. */
This will generate swap files of the format:
[._]*.s[a-v][a-z]
[._]*.sw[a-p]
[._]s[a-v][a-z]
[._]sw[a-p]
Which is pretty much what is included in github's own gitignore file for VIM.
As others have correctly noted, this .gitignore will also ignore .svg image files and .swf adobe flash files.
On Windows, the location can be found here. I didn't find any documentation on the internet for this, and this wasn't immediately obvious to me:

In case you want to use it for copy protection and you need it to return always the same serial on one computer (of course as far as first hdd or ssd is not changed) I would recommend code below. For ManagementClass you need to add reference to System.Management. P.S. Without "InterfaceType" and "DeviceID" check that method can return serial of random disk or serial of USB flash drive which connected to pc right now.
public static string GetSerial()
{
try
{
var mc = new ManagementClass("Win32_DiskDrive");
var moc = mc.GetInstances();
var res = string.Empty;
var resList = new List<string>(moc.Count);
foreach (ManagementObject mo in moc)
{
try
{
if (mo["InterfaceType"].ToString().Replace(" ", string.Empty) == "USB")
{
continue;
}
}
catch
{
}
try
{
res = mo["SerialNumber"].ToString().Replace(" ", string.Empty);
resList.Add(res);
if (mo["DeviceID"].ToString().Replace(" ", string.Empty).Contains("0"))
{
if (!string.IsNullOrWhiteSpace(res))
{
return res;
}
}
}
catch
{
}
}
res = resList[0];
if (!string.IsNullOrWhiteSpace(res))
{
return res;
}
}
catch
{
}
return string.Empty;
}
+1 for distinguishing between "empty" and NULL. I agree that "empty" should mean "valid, but blank" and "NULL" should mean "invalid."
So I'd answer your question like this:
empty when I want a valid default value that may or may not be changed, for example, a user's middle name.
NULL when it is an error if the ensuing code does not set the value explicitly.
If you are using Typescript, presumably you want to use the type safety; in which case naked Object and 'any' are counterindicated.
Better to not use Object or {}, but some named type; or you might be using an API with specific types, which you need extend with your own fields. I've found this to work:
class Given { ... } // API specified fields; or maybe it's just Object {}
interface PropAble extends Given {
props?: string; // you can cast any Given to this and set .props
// '?' indicates that the field is optional
}
let g:Given = getTheGivenObject();
(g as PropAble).props = "value for my new field";
// to avoid constantly casting:
let k:PropAble = getTheGivenObject();
k.props = "value for props";
Yes you can do that by just creating a BroadcastReceiver
that calls your Service
when your Application boots. Here is a complete answer given by me.
Android - Start service on boot
If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Just declare your Service
as declared normally.
Sorting by an ISO formatted date can be expensive, unless you limit the clients to the latest and best browsers, which can create the correct timestamp by Date-parsing the string.
If you are sure of your input, and you know it will always be yyyy-mm-ddThh:mm:ss and GMT (Z) you can extract the digits from each member and compare them like integers
array.sort(function(a,b){
return a.updated_at.replace(/\D+/g,'')-b.updated_at.replace(/\D+/g,'');
});
If the date could be formatted differently, you may need to add something for iso challenged folks:
Date.fromISO: function(s){
var day, tz,
rx=/^(\d{4}\-\d\d\-\d\d([tT ][\d:\.]*)?)([zZ]|([+\-])(\d\d):(\d\d))?$/,
p= rx.exec(s) || [];
if(p[1]){
day= p[1].split(/\D/).map(function(itm){
return parseInt(itm, 10) || 0;
});
day[1]-= 1;
day= new Date(Date.UTC.apply(Date, day));
if(!day.getDate()) return NaN;
if(p[5]){
tz= (parseInt(p[5], 10)*60);
if(p[6]) tz+= parseInt(p[6], 10);
if(p[4]== '+') tz*= -1;
if(tz) day.setUTCMinutes(day.getUTCMinutes()+ tz);
}
return day;
}
return NaN;
}
if(!Array.prototype.map){
Array.prototype.map= function(fun, scope){
var T= this, L= T.length, A= Array(L), i= 0;
if(typeof fun== 'function'){
while(i< L){
if(i in T){
A[i]= fun.call(scope, T[i], i, T);
}
++i;
}
return A;
}
}
}
}
You need to:
Go to cloud.google.com
Go to my Console
Choose your Project
Choose Networking > VPC network
Choose "Firewalls rules"
Choose "Create Firewall Rule"
To apply the rule to select VM instances, select Targets > "Specified target tags", and enter into "Target tags" the name of the tag. This tag will be used to apply the new firewall rule onto whichever instance you'd like. Then, make sure the instances have the network tag applied.
To allow incoming TCP connections to port 9090, in "Protocols and Ports" enter tcp:9090
Click Create
I hope this helps you.

To directly answer your two subquestions: No, you cannot do this with Ajax, nor can you calculate it with PHP.
What I have done in the past is use a trigger from the iframe'd page in window.onload
(NOT domready
, as it can take a while for images to load) to pass the page's body height to the parent.
<body onload='parent.resizeIframe(document.body.scrollHeight)'>
Then the parent.resizeIframe
looks like this:
function resizeIframe(newHeight)
{
document.getElementById('blogIframe').style.height = parseInt(newHeight,10) + 10 + 'px';
}
Et voila, you have a robust resizer that triggers once the page is fully rendered with no nasty contentdocument
vs contentWindow
fiddling :)
Sure, now people will see your iframe at default height first, but this can be easily handled by hiding your iframe at first and just showing a 'loading' image. Then, when the resizeIframe
function kicks in, put two extra lines in there that will hide the loading image, and show the iframe for that faux Ajax look.
Of course, this only works from the same domain, so you may want to have a proxy PHP script to embed this stuff, and once you go there, you might as well just embed your blog's RSS feed directly into your site with PHP.

}
This solution might also appeal to you, depending on how your mind works:
from pathlib import Path
def get_size(path = Path('.')):
""" Gets file size, or total directory size """
if path.is_file():
size = path.stat().st_size
elif path.is_dir():
size = sum(file.stat().st_size for file in path.glob('*.*'))
return size
def format_size(path, unit="MB"):
""" Converts integers to common size units used in computing """
bit_shift = {"B": 0,
"kb": 7,
"KB": 10,
"mb": 17,
"MB": 20,
"gb": 27,
"GB": 30,
"TB": 40,}
return "{:,.0f}".format(get_size(path) / float(1 << bit_shift[unit])) + " " + unit
# Tests and test results
>>> get_size("d:\\media\\bags of fun.avi")
'38 MB'
>>> get_size("d:\\media\\bags of fun.avi","KB")
'38,763 KB'
>>> get_size("d:\\media\\bags of fun.avi","kb")
'310,104 kb'
This is the bash script to print commands for syncing two directories
dir1=/tmp/path_to_dir1
dir2=/tmp/path_to_dir2
diff -rq $dir1 $dir2 | sed -e "s|Only in $dir2\(.*\): \(.*\)|cp -r $dir2\1/\2 $dir1\1|" | sed -e "s|Only in $dir1\(.*\): \(.*\)|cp -r $dir1\1/\2 $dir2\1|"
You shouldn't need to know the index in most circumstances. You can do this:
my @arr = (1, 2, 3);
foreach (@arr) {
$_++;
}
print join(", ", @arr);
In this case, the output would be 2, 3, 4 as foreach sets an alias to the actual element, not just a copy.
If after the installation curl-dev luarocks does not see the headers:
find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h
luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/
One possible solution which works for me:

In more recent versions of SQL Server Management studio, you can now right click on a database and 'Take Database Offline'. This gives you the option to Drop All Active Connections to the database.
Before using foreach
for iteration, reverse the list by the reverse
method:
myList.Reverse();
foreach( List listItem in myList)
{
Console.WriteLine(listItem);
}
You can use
rspec spec/controllers/groups_controller_spec.rb:<line_number>
line number should be line number of 'describe' or 'it' lines so that it will run tests present in that particular block. instead it will execute all the lines next to line_number.
also you can create block with custom name and then can execute those blocks only.
LINQ-to-SQL is a remarkable piece of technology that is very simple to use, and by and large generates very good queries to the back end. LINQ-to-EF was slated to supplant it, but historically has been extremely clunky to use and generated far inferior SQL. I don't know the current state of affairs, but Microsoft promised to migrate all the goodness of L2S into L2EF, so maybe it's all better now.
Personally, I have a passionate dislike of ORM tools (see my diatribe here for the details), and so I see no reason to favour L2EF, since L2S gives me all I ever expect to need from a data access layer. In fact, I even think that L2S features such as hand-crafted mappings and inheritance modeling add completely unnecessary complexity. But that's just me. ;-)
ng-pristine ($pristine)
Boolean True if the form/input has not been used yet (not modified by the user)
ng-dirty ($dirty)
Boolean True if the form/input has been used (modified by the user)
$setDirty(); Sets the form to a dirty state. This method can be called to add the 'ng-dirty' class and set the form to a dirty state (ng-dirty class). This method will propagate current state to parent forms.
$setPristine(); Sets the form to its pristine state. This method sets the form's $pristine state to true, the $dirty state to false, removes the ng-dirty class and adds the ng-pristine class. Additionally, it sets the $submitted state to false. This method will also propagate to all the controls contained in this form.
Setting a form back to a pristine state is often useful when we want to 'reuse' a form after saving or resetting it.
In 2019 with CSS3 you can do this without Javascript at all. I frequently make sticky headers like this:

_x000D_
header {_x000D_

If you want a native bash
solution
for file in /home/user/*; do
echo "${file##*/}"
done
The above uses Parameter Expansion which is native to the shell and does not require a call to an external binary such as basename
However, might I suggest just using find
find /home/user -type f -printf "%f\n"
Another way of doing this is by generating the select query. Play with this fiddle.
SELECT CONCAT('SELECT ', group_concat(`COLUMN_NAME` SEPARATOR '+'), ' FROM scorecard')
FROM `INFORMATION_SCHEMA`.`COLUMNS`
WHERE `TABLE_SCHEMA` = (select database())
AND `TABLE_NAME` = 'scorecard'
AND `COLUMN_NAME` LIKE 'mark%';
The query above will generate another query that will do the selecting for you.
Sample result:
SELECT mark1+mark2+mark3 FROM scorecard
You won't have to manually add all the columns anymore.
I have modified one of the answers (by @op1ekun):
123-(apple(?=-)|banana(?=-)|(?!-))-?456
The reason is that the answer from @op1ekun also matches "123-apple456"
, without the hyphen after apple.
Using an apostrophe ’

What you want to do is a combination of part of 1 and all of 2.
You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.
But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.
From the javadoc:
Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.
The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.
Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:
import static org.mockito.Mockito.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
class ClassWithStatics {
public static String getString() {
return "String";
}
public static int getInt() {
return 1;
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
@Test
public void test() {
PowerMockito.mockStatic(ClassWithStatics.class);
when(ClassWithStatics.getString()).thenReturn("Hello!");
System.out.println("String: " + ClassWithStatics.getString());
System.out.println("Int: " + ClassWithStatics.getInt());
}
}
The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.
Find timestamp from DateTime:

{
TimeZoneInfo NYTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
DateTime NyTime = TimeZoneInfo.ConvertTime(value, NYTimeZone);
TimeZone localZone = TimeZone.CurrentTimeZone;
System.Globalization.DaylightTime dst = localZone.GetDaylightChanges(NyTime.Year);
NyTime = NyTime.AddHours(-1);
DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();
TimeSpan span = (NyTime - epoch);
return (long)Convert.ToDouble(span.TotalSeconds);

ngModel.$formatters.unshift(validate);

KISS : Keep it simple, stupid
Way A: Implement an own SortableBindingList class when like to use DataBinding and sorting.
Way B: Use a List<string> sorting works also but does not work with DataBinding.
select f1,
CASE WHEN f1 = 't' THEN COUNT(*)
WHEN f1 = 'f' THEN COUNT(*)
END AS counts,
(SELECT COUNT(*) FROM mytable) AS total_counts
from mytable
group by f1
Or Maybe this
SELECT SUM(CASE WHEN f1 = 't' THEN 1 END) AS t,
SUM(CASE WHEN f1 = 'f' THEN 1 END) AS f,
SUM(CASE WHEN f1 NOT IN ('t','f') OR f1 IS NULL THEN 1 END) AS others,
SUM(CASE WHEN f1 IS NOT NULL OR f1 IS NULL THEN 1 ELSE 0 END) AS total_count
FROM mytable;
I ran into a similar problem and just passed the end of the array to the ArrayList.add()
index param like so:
public class Stack {
private ArrayList<String> stringList = new ArrayList<String>();
RandomStringGenerator rsg = new RandomStringGenerator();
private void push(){
String random = rsg.randomStringGenerator();
stringList.add(stringList.size(), random);
}
}
def is_prime(num):
"""Returns True if the number is prime
else False."""
if num == 0 or num == 1:
return False
for x in range(2, num):
if num % x == 0:
return False
else:
return True
>> filter(is_prime, range(1, 20))
[2, 3, 5, 7, 11, 13, 17, 19]
We will get all the prime numbers upto 20 in a list. I could have used Sieve of Eratosthenes but you said you want something very simple. ;)
DirectoryInfo di = Directory.CreateDirectory(path);

Hope that helps out!
You need to separate the arguments from the file path:
powershell.exe -noexit "& 'D:\Work\SQLExecutor.ps1 ' -gettedServerName 'MY-PC'"
Another option that may ease the syntax using the File parameter and positional parameters:
powershell.exe -noexit -file "D:\Work\SQLExecutor.ps1" "MY-PC"
On the model set $incrementing
to false
public $incrementing = false;
This will stop it from thinking it is an auto increment field.
Create an output file and custom function:
outputFile = open('outputfile.log', 'w')
def printing(text):
print(text)
if outputFile:
outputFile.write(str(text))
Then instead of print(text) in your code, call printing function.
printing("START")
printing(datetime.datetime.now())
printing("COMPLETE")
printing(datetime.datetime.now())
You can do it using foreach loop.
$arrayVal = array(1,2,3,1,2,3,1,2,3,4,4,5,6,4,5,6,88);
$set_array = array();
foreach ($array as $value) {
$set_array[$value]++;
}
print_r($set_array);
Output :-
Array( [1] => 3
[2] => 3
[3] => 3
[4] => 3
[5] => 2
[6] => 2
[88] => 1
)
Your regex should work 'as-is'. Assuming that it is doing what you want it to.
wordA(\s*)wordB(?! wordc)
This means match wordA
followed by 0 or more spaces followed by wordB
, but do not match if followed by wordc
. Note the single space between ?!
and wordc
which means that wordA wordB wordc
will not match, but wordA wordB wordc
will.
Here are some example matches and the associated replacement output:
Note that all matches are replaced no matter how many spaces. There are a couple of other points: -
(?! wordc)
is a negative lookahead, so you wont match lines wordA wordB wordc
which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?!
to match the whitespace. You may want to be more precise and use (?!\swordc)
. If you want to match against more than one space before wordc you can use (?!\s*wordc)
for 0 or more spaces or (?!\s*+wordc)
for 1 or more spaces depending on what your intention is.
Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.
*
will match 0 or more spaces so it will match wordAwordB. You may want to consider +
if you want at least one space.
(\s*)
- the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s
.
Update based on comment
Hello the problem is not the expression but the HTML out put that are not considered as whitespace. it's a Joomla website.
Preserving your original regex you can use:
wordA((?:\s| )*)wordB(?!(?:\s| )wordc)
The only difference is that not the regex matches whitespace OR
. I replaced wordc
with \swordc
since that is more explicit. Note as I have already pointed out that the negative lookahead ?!
will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.
Example matches:
where is the file created?
In the application's current working directory. You can use os.getcwd
to check it, and os.chdir
to change it.
Opening file in the root directory probably fails due to lack of privileges.
import numpy as np
def sigmoid(x):
s = 1 / (1 + np.exp(-x))
return s
result = sigmoid(0.467)
print(result)
The above code is the logistic sigmoid function in python.
If I know that x = 0.467
,
The sigmoid function, F(x) = 0.385
. You can try to substitute any value of x you know in the above code, and you will get a different value of F(x)
.
Try this regex:
"href\\s*=\\s*(?:\"(?<1>[^\"]*)\"|(?<1>\\S+))"
You will get more help from discussions over:

Hope its helpful.
$result2 is resource link not a string to echo

I don't believe that Distinct() is guaranteed to maintain the order of the set.
Try pulling out an anonymous type first and distinct/sort on that before you convert to string:
var ud = env.Select(d => new
{
d.ReportDate.Year,
d.ReportDate.Month,
FormattedDate = d.ReportDate.ToString("yyyy-MMM")
})
.Distinct()
.OrderByDescending(d => d.Year)
.ThenByDescending(d => d.Month)
.Select(d => d.FormattedDate);
var bordT = $('img').outerWidth() - $('img').innerWidth();
var paddT = $('img').innerWidth() - $('img').width();
var margT = $('img').outerWidth(true) - $('img').outerWidth();
var formattedBord = bordT + 'px';
var formattedPadd = paddT + 'px';
var formattedMarg = margT + 'px';
Check the jQuery API docs for information on each:
Here's the edited jsFiddle showing the result.
You can perform the same type of operations for the Height to get its margin, border, and padding.
Using the currently recommended (as of 2015) APIs (per the Node docs), this is what I do:
var fs = require('fs');
function fileExists(filePath)
{
try
{
return fs.statSync(filePath).isFile();
}
catch (err)
{
return false;
}
}
In response to the EPERM issue raised by @broadband in the comments, that brings up a good point. fileExists() is probably not a good way to think about this in many cases, because fileExists() can't really promise a boolean return. You may be able to determine definitively that the file exists or doesn't exist, but you may also get a permissions error. The permissions error doesn't necessarily imply that the file exists, because you could lack permission to the directory containing the file on which you are checking. And of course there is the chance you could encounter some other error in checking for file existence.
So my code above is really doesFileExistAndDoIHaveAccessToIt(), but your question might be doesFileNotExistAndCouldICreateIt(), which would be completely different logic (that would need to account for an EPERM error, among other things).
While the fs.existsSync answer addresses the question asked here directly, that is often not going to be what you want (you don't just want to know if "something" exists at a path, you probably care about whether the "thing" that exists is a file or a directory).
The bottom line is that if you're checking to see if a file exists, you are probably doing that because you intend to take some action based on the result, and that logic (the check and/or subsequent action) should accommodate the idea that a thing found at that path may be a file or a directory, and that you may encounter EPERM or other errors in the process of checking.
As your project is a console project you can pass the path to the text files that you want to read via the string[] args
static void Main(string[] args)
{
}
Within Main you can check if arguments are passed
if (args.Length == 0){ System.Console.WriteLine("Please enter a parameter");}
Extract an argument
string fileToRead = args[0];
Nearly all languages support the concept of argument passing and follow similar patterns to C#.
For more C# specific see http://msdn.microsoft.com/en-us/library/vstudio/cb20e19t.aspx
A reliable way to construct a File instance on a resource retrieved from a jar is it to copy the resource as a stream into a temporary File (the temp file will be deleted when the JVM exits):
public static File getResourceAsFile(String resourcePath) {
try {
InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
if (in == null) {
return null;
}
File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
tempFile.deleteOnExit();
try (FileOutputStream out = new FileOutputStream(tempFile)) {
//copy stream
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = in.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
}
}
return tempFile;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
Yes, set the cell as a RANGE object one time and then use that RANGE object in your code:
Sub RangeExample()
Dim MyRNG As Range
Set MyRNG = Sheets("Sheet1").Cells(23, 4)
Debug.Print MyRNG.Value
End Sub
Alternately you can simply store the value of that cell in memory and reference the actual value, if that's all you really need. That variable can be Long or Double or Single if numeric, or String:
Sub ValueExample()
Dim MyVal As String
MyVal = Sheets("Sheet1").Cells(23, 4).Value
Debug.Print MyVal
End Sub

Assuming you mean "list" where you say "array", you can do
if item in my_list:
# whatever
This works for any collection, not just for lists. For dictionaries, it checks whether the given key is present in the dictionary.
<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;
echo date("H:i", $elapsed);
?>
It's because you have:
def readTTable(fname):
try:
without a matching except
block after the try:
block. Every try
must have at least one matching except
.

Step 1: Keep going git rebase --continue
Step 2: fix CONFLICTS then git add .
Back to step 1, now if it says no changes ..
then run git rebase --skip

If you just want to quit rebase run git rebase --abort
Once all changes are done run git commit -m "rebase complete"
and you are done.
Note: If you don't know what's going on and just want to go back to where the repo was, then just do:
git rebase --abort

Please note that one should define a Handler
and a Runnable
in class scope, so that it is created once.removeCallbacks(Runnable)
works correctly unless one defines them multiple times. Please look at following examples for better understanding:
Incorrect way :
public class FooActivity extends Activity {
private void handleSomething(){
Handler handler = new Handler();
Runnable runnable = new Runnable() {
@Override
public void run() {
doIt();
}
};
if(shouldIDoIt){
//doIt() works after 3 seconds.
handler.postDelayed(runnable, 3000);
} else {
handler.removeCallbacks(runnable);
}
}
public void onClick(View v){
handleSomething();
}
}
If you call onClick(..)
method, you never stop doIt()
method calling before it call. Because each time creates new Handler
and new Runnable
instances. In this way, you lost necessary references which belong to handler and runnable instances.
Correct way :
public class FooActivity extends Activity {
Handler handler = new Handler();
Runnable runnable = new Runnable() {
@Override
public void run() {
doIt();
}
};
private void handleSomething(){
if(shouldIDoIt){
//doIt() works after 3 seconds.
handler.postDelayed(runnable, 3000);
} else {
handler.removeCallbacks(runnable);
}
}
public void onClick(View v){
handleSomething();
}
}
In this way, you don't lost actual references and removeCallbacks(runnable)
works successfully.
Key sentence is that 'define them as global in your Activity
or Fragment
what you use'.
For the sake of completeness, I'd like to add that you cannot reverse String#split in general, as it accepts a regular expression.
"hello__world".split("_+");
Yields ["hello", "world"]
.
"hello_world".split("_+");
Yields ["hello", "world"]
.
These yield identical results from a different starting point. splitting is not a one-to-one operation, and is thus non-reversible.
This all being said, if you assume your parameter to be a fixed string, not regex, then you can certainly do this using one of the many posted answers.

To my knowledge the use of the keyword new, does relatively the same thing as malloc(sizeof identifier). The code below demonstrates how to use the keyword new.
void main(void){
int* test;
test = tester();
printf("%d",*test);
system("pause");
return;
}
int* tester(void){
int *retMe;
retMe = new int;//<----Here retMe is getting malloc for integer type
*retMe = 12;<---- Initializes retMe... Note * dereferences retMe
return retMe;
}

Components specify behavior and operate on properties. Properties are shared between all components by a reference and get updates for free. This means no large overhead for message passing. If there's any questions I'll try to answer as best I can.
a = 'have a nice day'
symbol = 'abcdefghijklmnopqrstuvwxyz'
for key in symbol:
print key, a.count(key)
Use iFunBox. It's free, Mac/Win compatible. Just make an ad hoc build and save somewhere. Install from iFunBox. I load all my test ad hoc release builds on my devices for testing before release using this method. Who has time to fiddle around with iTunes?
var ret = "data-123".replace('data-','');_x000D_
console.log(ret); //prints: 123
_x000D_
For all occurrences to be discarded use:
var ret = "data-123".replace(/data-/g,'');
PS: The replace function returns a new string and leaves the original string unchanged, so use the function return value after the replace() call.
Both versions using sets didn't work for me (tested with MySQL 5.5). The function ELT() returns the whole set. Considering the WHILE statement is only avaible in PROCEDURE context i added it to my solution:
DROP PROCEDURE IF EXISTS __main__;
DELIMITER $
CREATE PROCEDURE __main__()
BEGIN
SET @myArrayOfValue = '2,5,2,23,6,';
WHILE (LOCATE(',', @myArrayOfValue) > 0)
DO
SET @value = LEFT(@myArrayOfValue, LOCATE(',',@myArrayOfValue) - 1);
SET @myArrayOfValue = SUBSTRING(@myArrayOfValue, LOCATE(',',@myArrayOfValue) + 1);
END WHILE;
END;
$
DELIMITER ;
CALL __main__;
To be honest, i don't think this is a good practice. Even if its realy necessary, this is barely readable and quite slow.
Accordingly to W3C checked input's attribute can be absent/ommited or have "checked" as its value. This does not invalidate other values because there's no restriction to the browser implementation to allow values like "true", "on", "yes" and so on. To guarantee that you'll write a cross-browser checkbox/radio use checked="checked", as recommended by W3C.
disabled, readonly and ismap input's attributes go on the same way.
EDITED
empty is not a valid value for checked, disabled, readonly and ismap input's attributes, as warned by @Quentin
I use:
from pathlib import Path
import platform
import tempfile
tempdir = Path("/tmp" if platform.system() == "Darwin" else tempfile.gettempdir())
This is because on MacOS, i.e. Darwin, tempfile.gettempdir()
and os.getenv('TMPDIR')
return a value such as '/var/folders/nj/269977hs0_96bttwj2gs_jhhp48z54/T'
; it is one that I do not always want.

The main point is this:
col-lg-*
col-md-*
col-xs-*
col-sm
define how many columns will there be in these different screen sizes.
Example: if you want there to be two columns in desktop screens and in phone screens you put two col-md-6
and two col-xs-6
classes in your columns.
If you want there to be two columns in desktop screens and only one column in phone screens (ie two rows stacked on top of each other) you put two col-md-6
and two col-xs-12
in your columns and because sum will be 24 they will auto stack on top of each other, or just leave xs
style out.
You can't. So:
rm -rf .git/
git init
git add -A
git commit -m 'Your new commit message'
Like this:
int main()
{
int arr[2][5] =
{
{1,8,12,20,25},
{5,9,13,24,26}
};
}
This should be covered by your C++ textbook: which one are you using?
Anyway, better, consider using std::vector
or some ready-made matrix class e.g. from Boost.
You cannot add JavaScript variable to HTML code.
For this you need to do in following way.
<html>
<head>
<script type="text/javscript">
var number = 123;
document.addEventListener('DOMContentLoaded', function() {
document.getElementByTagName("h1").innerHTML("the value for number is: " + number);
});
</script>
</head>
<body>
<h1></h1>
</body>
</html>
Depending on size and scale of the difficultly, you could create a scratch (temporary) branch and commit the current work there.
Then switch to and checkout your original branch, and pick the appropriate files from the scratch commit.
At least you would have a permanent record of the current and previous states to work from (until you delete that scratch branch).
On jQueryUi 1.9 I've managed to get it to work through an additional data value and a combination of beforeShow and onSelect functions:
$( ".datepicker" ).datepicker({
beforeShow: function( el ){
// set the current value before showing the widget
$(this).data('previous', $(el).val() );
},
onSelect: function( newText ){
// compare the new value to the previous one
if( $(this).data('previous') != newText ){
// do whatever has to be done, e.g. log it to console
console.log( 'changed to: ' + newText );
}
}
});
Works for me :)
'It' requires a dll file called cvextern.dll . 'It' can be either your own cs file or some other third party dll which you are using in your project.
To call native dlls to your own cs file, copy the dll into your project's root\lib directory and add it as an existing item. (Add -Existing item) and use Dllimport with correct location.
For third party , copy the native library to the folder where the third party library resides and add it as an existing item.
After building make sure that the required dlls are appearing in Build folder. In some cases it may not appear or get replaced in Build folder. Delete the Build folder manually and build again.
You may need to check if variable declared and has correct type.
if (!isset($res) || !is_object($res)) {
$res = new \stdClass();
// With php7 you also can create an object in several ways.
// Object that implements some interface.
$res = new class implements MyInterface {};
// Object that extends some object.
$res = new class extends MyClass {};
}
$res->success = true;
You need to use a pointer to a member function, not just a pointer to a function.
class A {
int f() { return 1; }
public:
int (A::*x)();
A() : x(&A::f) {}
};
int main() {
A a;
std::cout << (a.*a.x)();
return 0;

This answer applies to using gVim on Windows 10. I cannot guarantee the same results for other operating systems.
Add:
set nobackup
set noswapfile
set noundofile
To your _vimrc file.
Note: This is the direct answer to the question (for Windows 10) and probably not the safest thing to do (read the other answers), but this is the fastest solution in my case.
Use This Query :
Select
S.name + '.' + T.name As TableName ,
SUM( P.rows ) As RowCont
From sys.tables As T
Inner Join sys.partitions As P On ( P.OBJECT_ID = T.OBJECT_ID )
Inner Join sys.schemas As S On ( T.schema_id = S.schema_id )
Where
( T.is_ms_shipped = 0 )
AND
( P.index_id IN (1,0) )
And
( T.type = 'U' )
Group By S.name , T.name
Order By SUM( P.rows ) Desc

You can't close a current window or any window or page that is opened using '_self' But you can do this
var customWindow = window.open('', '_blank', '');
customWindow.close();
Here I think it's worth mentioning SORT BY
and ORDER BY
both clauses and why they different,
SELECT * FROM <table_name> SORT BY <column_name> DESC LIMIT 2
If you are using SORT BY
clause it sort data per reducer which means if you have more than one MapReduce task it will result partially ordered data. On the other hand, the ORDER BY
clause will result in ordered data for the final Reduce task. To understand more please refer to this link.
SELECT * FROM <table_name> ORDER BY <column_name> DESC LIMIT 2
Note: Finally, Even though the accepted answer contains SORT BY
clause, I mostly prefer to use ORDER BY
clause for the general use case to avoid any data loss.
Approach: 1
Given original string
format: 2019/03/04 00:08:48
you can use
updated_df = df['timestamp'].astype('datetime64[ns]')
The result will be in this datetime
format: 2019-03-04 00:08:48
Approach: 2
updated_df = df.astype({'timestamp':'datetime64[ns]'})
Thing
is an inner class with an automatic connection to an instance of Hello
. You get a compile error because there is no instance of Hello
for it to attach to. You can fix it most easily by changing it to a static nested class which has no connection:
static class Thing
You should put this line in your application context:

Look at all the issues surrounding trying to make divs perform like tables. They had to add table-xxx to mimic table layouts
Tables are supported and work very well in all browsers. Why ditch them? the fact that they had to mimic them is proof they did their job and well.
In my opinion use the best tool for the job and if you want tabulated data or something that resembles tabulated data tables just work.
Very Late reply I know but worth voicing.
You need to provide configurations considering your Spring Boot Version and the version of libraries it downloads based on the same.
Use below only if your Spring Boot setup has downloaded Hibernate v4.
spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy
Hibernate 5 doesn't support above.
If your Spring Boot Setup has downloaded Hibernate v5.x, then prefer below definition:
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
IMPORTANT:
In your Spring Boot application development, you should prefer to use annotation: @SpringBootApplication
which has been super-annotated with: @SpringBootConfiguration and @EnableAutoConfiguration
NOW If your entity classes are in different package than the package in which your Main Class resides, Spring Boot won't scan those packages.
Thus you need to explicitly define Annotation: @EntityScan(basePackages = { "com.springboot.entities" })
This annotation scans JPA based annotated entity classes (and others like MongoDB, Cassandra etc)
NOTE:
"com.springboot.entities" is the custom package name.
Following is the way I had defined Hibernate and JPA based properties at application.properties to create Tables:-
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3333/development?useSSL=true spring.datasource.username=admin
spring.datasource.password=spring.jpa.open-in-view=false
spring.jpa.hibernate.ddl-auto=create
spring.jpa.generate-ddl=true
spring.jpa.hibernate.use-new-id-generator-mappings=true
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.naming.strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.format_sql=true
I am able to create tables using my above mentioned configuration.
Refer it and change your code wherever applicable.

Just using strings, for me is a good solution, less problems with mysql. Detects the current format and changes it if necessary, this solution is only for spanish/french format and english format, without use php datetime function.
class dateTranslator {
public static function translate($date, $lang) {
$divider = '';
if (empty($date)){
return null;
}
if (strpos($date, '-') !== false) {
$divider = '-';
} else if (strpos($date, '/') !== false) {
$divider = '/';
}
//spanish format DD/MM/YYYY hh:mm
if (strcmp($lang, 'es') == 0) {
$type = explode($divider, $date)[0];
if (strlen($type) == 4) {
$date = self::reverseDate($date,$divider);
}
if (strcmp($divider, '-') == 0) {
$date = str_replace("-", "/", $date);
}
//english format YYYY-MM-DD hh:mm
} else {
$type = explode($divider, $date)[0];
if (strlen($type) == 2) {
$date = self::reverseDate($date,$divider);
}
if (strcmp($divider, '/') == 0) {
$date = str_replace("/", "-", $date);
}
}
return $date;
}
public static function reverseDate($date) {
$date2 = explode(' ', $date);
if (count($date2) == 2) {
$date = implode("-", array_reverse(preg_split("/\D/", $date2[0]))) . ' ' . $date2[1];
} else {
$date = implode("-", array_reverse(preg_split("/\D/", $date)));
}
return $date;
}
USE
dateTranslator::translate($date, 'en')
The code is
document.addEventListener('keydown', function(event){
alert(event.keyCode);
} );
This return the ascii code of the key. If you need the key representation, use event.key (This will return 'a', 'o', 'Alt'...)
Such debugging is part of the development process and should not be the issue at runtime.
Methods don't trust other methods. They all trust you. That is the process of developing. Fix all bugs. Then methods don't have to "trust". There should be no doubt.
So, write it as it should be. Do not make methods check wether other methods are working correctly. That should be tested by the developer when they wrote that function. If you suspect a method to be not doing what you want, debug it.
tigeravatar and Jean-François Corbett suggested to use this formula to generate the string right of the last occurrence of the "\" character
=TRIM(RIGHT(SUBSTITUTE(A1,"\",REPT(" ",LEN(A1))),LEN(A1)))
If the character used as separator is space, " ", then the formula has to be changed to:
=SUBSTITUTE(RIGHT(SUBSTITUTE(A1," ",REPT("{",LEN(A1))),LEN(A1)),"{","")
No need to mention, the "{" character can be replaced with any character that would not "normally" occur in the text to process.
lambda
is an anonymous function, it is equivalent to:
def func(p):
return p.totalScore
Now max
becomes:
max(players, key=func)
But as def
statements are compound statements they can't be used where an expression is required, that's why sometimes lambda
's are used.
Note that lambda
is equivalent to what you'd put in a return statement of a def
. Thus, you can't use statements inside a lambda
, only expressions are allowed.
What does max
do?
max(a, b, c, ...[, key=func]) -> value
With a single iterable argument, return its largest item. With two or more arguments, return the largest argument.
So, it simply returns the object that is the largest.
How does key
work?
By default in Python 2 key
compares items based on a set of rules based on the type of the objects (for example a string is always greater than an integer).
To modify the object before comparison, or to compare based on a particular attribute/index, you've to use the key
argument.
Example 1:
A simple example, suppose you have a list of numbers in string form, but you want to compare those items by their integer value.
>>> lis = ['1', '100', '111', '2']
Here max
compares the items using their original values (strings are compared lexicographically so you'd get '2'
as output) :
>>> max(lis)
'2'
To compare the items by their integer value use key
with a simple lambda
:
>>> max(lis, key=lambda x:int(x)) # compare `int` version of each item
'111'
Example 2: Applying max
to a list of tuples.
>>> lis = [(1,'a'), (3,'c'), (4,'e'), (-1,'z')]
By default max
will compare the items by the first index. If the first index is the same then it'll compare the second index. As in my example, all items have a unique first index, so you'd get this as the answer:
>>> max(lis)
(4, 'e')
But, what if you wanted to compare each item by the value at index 1? Simple: use lambda
:
>>> max(lis, key = lambda x: x[1])
(-1, 'z')
Comparing items in an iterable that contains objects of different type:
List with mixed items:
lis = ['1','100','111','2', 2, 2.57]
In Python 2 it is possible to compare items of two different types:
>>> max(lis) # works in Python 2
'2'
>>> max(lis, key=lambda x: int(x)) # compare integer version of each item
'111'
But in Python 3 you can't do that any more:
>>> lis = ['1', '100', '111', '2', 2, 2.57]
>>> max(lis)
Traceback (most recent call last):
File "<ipython-input-2-0ce0a02693e4>", line 1, in <module>
max(lis)
TypeError: unorderable types: int() > str()
But this works, as we are comparing integer version of each object:
>>> max(lis, key=lambda x: int(x)) # or simply `max(lis, key=int)`
'111'
This is extremely simple! Rather than importing odd modules for python or trying long commands you can take advantage of windows OS commands.
In windows, commands exist to change the command prompt text color. You can use this in python by starting with a: import os
Next you need to have a line changing the text color, place it were you want in your code.
os.system('color 4')
You can figure out the other colors by starting cmd.exe and typing color help.
The good part? Thats all their is to it, to simple lines of code. -Day
I've faced the very and suddenly same problem on my MAC. After having tried everything, I've finally deleted the folder /Users/Philippe/.android and create a new emulator.
You can use the following flags --single-branch
&& --depth
to download the specific branch and to limit the amount of history which will be downloaded.
You will clone the repo from a certain point in time and only for the given branch
git clone -b <branch> --single-branch <url> --depth <number of commits>
--[no-]single-branch
Clone only the history leading to the tip of a single branch, either specified by the
--branch
option or the primary branch remote’sHEAD
points at.Further fetches into the resulting repository will only update the
remote-tracking
branch for the branch this option was used for the initial cloning. If the HEAD at the remote did not point at any branch when--single-branch
clone was made, no remote-tracking branch is created.
--depth
Create a shallow clone with a history truncated to the specified number of commits
If you want to select the last child and need to be specific on the element type you can use the selector last-of-type
Here is an example:
$("div p:last-of-type").css("border", "3px solid red");
$("div span:last-of-type").css("border", "3px solid red");
<div id="example">
<p>This is paragraph 1</p>
<p>This is paragraph 2</p>
<span>This is paragraph 3</span>
<span>This is paragraph 4</span>
<p>This is paragraph 5</p>
</div>
In the example above both Paragraph 4 and Paragraph 5 will have a red border since Paragraph 5 is the last element of "p" type in the div and Paragraph 4 is the last "span" in the div.
I faced similar issue after upgrading to java 12, for me the solution was to update jacoco version <jacoco.version>0.8.3</jacoco.version>
To sort by second field only (thus where second fields match, those lines with matches remain in the order they are in the original without sorting on other fields) :
sort -k 2,2 -s orig_file > sorted_file
yes, you can swap these 2 queries
select * from table limit 5, 5
select * from table limit 0, 5
To update Angular CLI to a new version, you must update both the global package and your project's local package.
Global package:
npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest
Local project package:
rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
npm install --save-dev @angular/cli@latest
npm install
See the reference https://github.com/angular/angular-cli
A war file is simply a jar file with a war extension, but what makes it work is how the contents is actually structured.
The J2EE/Java EE tutorial can be a start:
http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/WebComponents3.html
And the Servlet specification contains the gory details:
http://java.sun.com/products/servlet/download.html
If you create a new web project in Eclipse (I am referring to the Java EE version), the structure is created for you and you can also tell it where your Appserver is installed and it will deploy and start the application for you.
Using the "Export->WAR file" option will let you save the war file.

I think you can use loc
if you need update two columns to same value:
df1.loc[df1['stream'] == 2, ['feat','another_feat']] = 'aaaa'
print df1
stream feat another_feat
a 1 some_value some_value
b 2 aaaa aaaa
c 2 aaaa aaaa
d 3 some_value some_value
If you need update separate, one option is use:
df1.loc[df1['stream'] == 2, 'feat'] = 10
print df1
stream feat another_feat
a 1 some_value some_value
b 2 10 some_value
c 2 10 some_value
d 3 some_value some_value
Another common option is use numpy.where
:
df1['feat'] = np.where(df1['stream'] == 2, 10,20)
print df1
stream feat another_feat
a 1 20 some_value
b 2 10 some_value
c 2 10 some_value
d 3 20 some_value
EDIT: If you need divide all columns without stream
where condition is True
, use:
print df1
stream feat another_feat
a 1 4 5
b 2 4 5
c 2 2 9
d 3 1 7
#filter columns all without stream
cols = [col for col in df1.columns if col != 'stream']
print cols
['feat', 'another_feat']
df1.loc[df1['stream'] == 2, cols ] = df1 / 2
print df1
stream feat another_feat
a 1 4.0 5.0
b 2 2.0 2.5
c 2 1.0 4.5
d 3 1.0 7.0
If working with multiple conditions is possible use multiple numpy.where
or numpy.select
:
df0 = pd.DataFrame({'Col':[5,0,-6]})
df0['New Col1'] = np.where((df0['Col'] > 0), 'Increasing',
np.where((df0['Col'] < 0), 'Decreasing', 'No Change'))
df0['New Col2'] = np.select([df0['Col'] > 0, df0['Col'] < 0],
['Increasing', 'Decreasing'],
default='No Change')
print (df0)
Col New Col1 New Col2
0 5 Increasing Increasing
1 0 No Change No Change
2 -6 Decreasing Decreasing
i used hasAnyRole('ROLE_ADMIN','ROLE_USER')
but i was getting bean creation below error
Error creating bean with name 'org.springframework.security.web.access.intercept.FilterSecurityInterceptor#0': Cannot create inner bean '(inner bean)' of type [org.springframework.security.web.access.expression.ExpressionBasedFilterInvocationSecurityMetadataSource] while setting bean property 'securityMetadataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#2': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.security.web.access.expression.ExpressionBasedFilterInvocationSecurityMetadataSource]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: Expected a single expression attribute for [/user/*]
then i tried
access="hasRole('ROLE_ADMIN') or hasRole('ROLE_USER')"
and it's working fine for me.
as one of my user is admin as well as user.
for this you need to add use-expressions="true" auto-config="true"
followed by http tag
<http use-expressions="true" auto-config="true" >.....</http>
On git for Windows you can also reinstall and select the Windows native certificate validation method (OpenSSL is default). This will skip the OpenSSL verification and instead use the Windows native one, which doesn't require maintaining a separate tool (OpenSSL) and certificates.
Worked perfectly for me :)
Whilst you can of course use the base64
module, you can also to use the codecs
module (referred to in your error message) for binary encodings (meaning non-standard & non-text encodings).
For example:
import codecs
my_bytes = b"Hello World!"
codecs.encode(my_bytes, "base64")
codecs.encode(my_bytes, "hex")
codecs.encode(my_bytes, "zip")
codecs.encode(my_bytes, "bz2")
This can come in useful for large data as you can chain them to get compressed and json-serializable values:
my_large_bytes = my_bytes * 10000
codecs.decode(
codecs.encode(
codecs.encode(
my_large_bytes,
"zip"
),
"base64"),
"utf8"
)

Since this seems to be the number one google hit on base64 encoding and iphone, I felt like sharing my experience with the code snippet above.
It works, but it is extremely slow. A benchmark on a random image (0.4 mb) took 37 seconds on native iphone. The main reason is probably all the OOP magic - single char NSStrings etc, which are only autoreleased after the encoding is done.
Another suggestion posted here (ab)uses the openssl library, which feels like overkill as well.
The code below takes 70 ms - that's a 500 times speedup. This only does base64 encoding (decoding will follow as soon as I encounter it)
+ (NSString *) base64StringFromData: (NSData *)data length: (int)length {
int lentext = [data length];
if (lentext < 1) return @"";
char *outbuf = malloc(lentext*4/3+4); // add 4 to be sure
if ( !outbuf ) return nil;
const unsigned char *raw = [data bytes];
int inp = 0;
int outp = 0;
int do_now = lentext - (lentext%3);
for ( outp = 0, inp = 0; inp < do_now; inp += 3 )
{
outbuf[outp++] = base64EncodingTable[(raw[inp] & 0xFC) >> 2];
outbuf[outp++] = base64EncodingTable[((raw[inp] & 0x03) << 4) | ((raw[inp+1] & 0xF0) >> 4)];
outbuf[outp++] = base64EncodingTable[((raw[inp+1] & 0x0F) << 2) | ((raw[inp+2] & 0xC0) >> 6)];
outbuf[outp++] = base64EncodingTable[raw[inp+2] & 0x3F];
}
if ( do_now < lentext )
{
char tmpbuf[2] = {0,0};
int left = lentext%3;
for ( int i=0; i < left; i++ )
{
tmpbuf[i] = raw[do_now+i];
}
raw = tmpbuf;
outbuf[outp++] = base64EncodingTable[(raw[inp] & 0xFC) >> 2];
outbuf[outp++] = base64EncodingTable[((raw[inp] & 0x03) << 4) | ((raw[inp+1] & 0xF0) >> 4)];
if ( left == 2 ) outbuf[outp++] = base64EncodingTable[((raw[inp+1] & 0x0F) << 2) | ((raw[inp+2] & 0xC0) >> 6)];
}
NSString *ret = [[[NSString alloc] initWithBytes:outbuf length:outp encoding:NSASCIIStringEncoding] autorelease];
free(outbuf);
return ret;
}
I left out the line-cutting since I didn't need it, but it's trivial to add.
For those who are interested in optimizing: the goal is to minimize what happens in the main loop. Therefore all logic to deal with the last 3 bytes is treated outside the loop.
Also, try to work on data in-place, without additional copying to/from buffers. And reduce any arithmetic to the bare minimum.
Observe that the bits that are put together to look up an entry in the table, would not overlap when they were to be orred together without shifting. A major improvement could therefore be to use 4 separate 256 byte lookup tables and eliminate the shifts, like this:
outbuf[outp++] = base64EncodingTable1[(raw[inp] & 0xFC)];
outbuf[outp++] = base64EncodingTable2[(raw[inp] & 0x03) | (raw[inp+1] & 0xF0)];
outbuf[outp++] = base64EncodingTable3[(raw[inp+1] & 0x0F) | (raw[inp+2] & 0xC0)];
outbuf[outp++] = base64EncodingTable4[raw[inp+2] & 0x3F];
Of course you could take it a whole lot further, but that's beyond the scope here.
That's interesting, but as far as I know the answer is a firm no. I don't see why you need a nested ID, since you'll usually cross it with another element that has the same nested ID. If you don't there's no point, if you do there's still very little point.
If you want to open an app directly to the App Store, you should use:
itms-apps://...
This way it will directly open the App Store app in the device, instead of going to iTunes first, then only open the App Store (when using just itms://)
Hope that helps.
EDIT: APR, 2017. itms-apps:// actually works again in iOS10. I tested it.
EDIT: APR, 2013. This no longer works in iOS5 and above. Just use
https://itunes.apple.com/app/id378458261
and there are no more redirects.
You can also use a fadeIn/FadeOut Combo, too....
$('.test').bind('click', function(){
$('.div1').fadeIn(500);
$('.div2').fadeOut(500);
$('.div3').fadeOut(500);
return false;
});
you can try this:
$('div#someDiv').height('');

If the Path is omitted the file will be saved automaticaly in the current directory. Try something like this:
ActiveWorkbook.SaveAs "Filename.xslx"
There is sort of a way around this:
struct Cell {
bool isParent;
struct Cell* child;
};
struct Cell;
typedef struct Cell Cell;
If you declare it like this, it properly tells the compiler that struct Cell and plain-ol'-cell are the same. So you can use Cell just like normal. Still have to use struct Cell inside of the initial declaration itself though.

Besides the solution of m79lkm above, my 2 cents on this topic is not to directly pipe the result in gzip but first dump it as a .sql file, and then gzip it. (Use && instead of | )
The dump itself will be faster. (for what I tested it was double as fast)
Otherwise you tables will be locked longer and the downtime/slow-responding of your application can bother the users. The mysqldump command is taking a lot of resources from your server.
So I would go for "&& gzip" instead of "| gzip"
Important: check for free disk space first with df -h
since you will need more then piping | gzip.
mysqldump -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql
-> which will also result in 1 file called dumpfilename.sql.gz
Furthermore the option --single-transaction
prevents the tables being locked but still result in a solid backup. So you might consider to use that option. See docs here
mysqldump --single-transaction -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql

Ozi, when you create a new datetime object as in datetime foo = new datetime(); foo is constructed with the time datetime.minvalue() in building a parameterized query, you could check to see if the values entered are equal to datetime.minvalue()
-Just a side thought. seems you have things working.
If anyone is looking for a quick fix for this, here's how you do it.
while (array[i] != '\0') i++;
The variable i will hold the used length of the array, not the entire initialized array. I know it's a late post, but it may help someone.
I know this is not a coding answer but it is what the OP wanted and what I have spent half the day trying to achieve - print from a web page with page numbers.
Yes, it is two steps instead of one but I haven't been able to find any CSS option despite several hours of searching. Real shame all the browsers removed the functionality that used to allow it.
you can follow the below command to install using the wheel file at your local
pip install /users/arpansaini/Downloads/h5py-3.0.0-cp39-cp39-macosx_10_9_x86_64.whl
In the Visual Studio Options Dialog -> Debugging -> Check the "Redirect All Output Window Text to the Immediate Window". Then go to your project settings and change the type from "Console Application" to "Windows Application". At that point Visual Studio does not open up a console window anymore, and the output is redirected to the Output window in Visual Studio. However, you cannot do anything "creative", like requesting key or text input, or clearing the console - you'll get runtime exceptions.
Addressing the first question, if you need to take several rows grouped by certain criteria with the other column with max value you can do something like this:
var query =
from u1 in table
join u2 in (
from u in table
group u by u.GroupId into g
select new { GroupId = g.Key, MaxStatus = g.Max(x => x.Status) }
) on new { u1.GroupId, u1.Status } equals new { u2.GroupId, Status = u2.MaxStatus}
select u1;
There is no builtin feature to wait for any process to finish.
You could send kill -0
to any PID found, so you don't get puzzled by zombies and stuff that will still be visible in ps
(while still retrieving the PID list using ps
).
Probably an evolution, it appears that inline css filters works nicely on elements, in a certain way.
Declaring a drop-shadow css filter, in an svg element, in both a class or inline does NOT works, as specified earlier.
But, at least in Firefox, with the following wizardry:
Appending the filter declaration inline, with javascript, after DOM load.
// Does not works, with regular dynamic css styling:
shadow0.oninput = () => {
rect1.style.filter = "filter:drop-shadow(0 0 " + shadow0.value + "rem black);"
}
// Okay! Inline styling, appending.
shadow1.oninput = () => {
rect1.style += " ;filter:drop-shadow(0 0 " + shadow1.value + "rem black);"
rect2.style += " ;filter:drop-shadow(0 0 " + shadow1.value + "rem black);"
}

Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.
.left {
float: left;
width: 125px;
text-align: right;
margin: 2px 10px;
display: inline;
}
.right {
float: left;
text-align: left;
margin: 2px 10px;
display: inline;
}
I solved this error by checking the package name in manifest and app build.gradle
.
In manifest:
I am using a package name as:
com.app.triapp
In app build.gradle:
defaultConfig {
applicationId "com.app.live"
}
After changed to com.app.triapp
in build.gradle
, solved my issue.
You add your ActionListener
twice to button
. So correct your code for button2
to
JButton button2 = new JButton("hello agin2");
panel.add(button2);
button2.addActionListener (new Action2());//note the button2 here instead of button
Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater
Perhaps use information_schema:
SELECT EXISTS(
SELECT *
FROM information_schema.tables
WHERE
table_schema = 'company3' AND
table_name = 'tableincompany3schema'
);
Encountered the same problem, to solve it, run the following git
commands.
git pull {url} --rebase
git push --set-upstream {url} master
You must have created the repository on github first.
$("#idform").validate({
rules: {
'roles': {
required: true,
},
},
messages: {
'roles': {
required: "One Option please",
},
}
});
if myVar
is null then if block not execute other-wise it will execute.
if (myVar != null) {...}
You have to be carefull when using Boolean.valueOf(string) or Boolean.parseBoolean(string). The reason for this is that the methods will always return false if the String is not equal to "true" (the case is ignored).
For example:
Boolean.valueOf("YES") -> false
Because of that behaviour I would recommend to add some mechanism to ensure that the string which should be translated to a Boolean follows a specified format.
For instance:
if (string.equalsIgnoreCase("true") || string.equalsIgnoreCase("false")) {
Boolean.valueOf(string)
// do something
} else {
// throw some exception
}
Looping over arrays and objects is a pretty common task, and it's good that you're wanting to learn how to do it. Generally speaking you can do a foreach
loop which cycles over each member, assigning it a new temporary name, and then lets you handle that particular member via that name:
foreach ($arr as $item) {
echo $item->sm_id;
}
In this example each of our values in the $arr
will be accessed in order as $item
. So we can print our values directly off of that. We could also include the index if we wanted:
foreach ($arr as $index => $item) {
echo "Item at index {$index} has sm_id value {$item->sm_id}";
}
It is not listed as a function in dplyr (yet): http://cran.rstudio.org/web/packages/dplyr/dplyr.pdf

datnames[which(datnames %in% oldnames)] <- newnames
colnames(dat) <- datnames
dat
}

</script>
has to be broken up because otherwise it would end the enclosing <script></script>
block too early. Really it should be split between the <
and the /
, because a script block is supposed (according to SGML) to be terminated by any end-tag open (ETAGO) sequence (i.e. </
):
Although the STYLE and SCRIPT elements use CDATA for their data model, for these elements, CDATA must be handled differently by user agents. Markup and entities must be treated as raw text and passed to the application as is. The first occurrence of the character sequence "
</
" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.
However in practice browsers only end parsing a CDATA script block on an actual </script>
close-tag.
In XHTML there is no such special handling for script blocks, so any <
(or &
) character inside them must be &escaped;
like in any other element. However then browsers that are parsing XHTML as old-school HTML will get confused. There are workarounds involving CDATA blocks, but it's easiest simply to avoid using these characters unescaped. A better way of writing a script element from script that works on either type of parser would be:
<script type="text/javascript">
document.write('\x3Cscript type="text/javascript" src="foo.js">\x3C/script>');
</script>
You can set the width like this :
function draw() {
var ctx = (a canvas context);
ctx.canvas.width = window.innerWidth;
ctx.canvas.height = window.innerHeight;
//...drawing code...
}
Try this,
<?php if ( ($cart->count_product) > 0) { ?>
<div class="my_class"><?php print $cart->count_product; ?></div>
<?php } else {
print '';
} ?>
Make sure your app_offline.htm file is at least 512 bytes long. A zero-byte app_offline.htm will have no effect.
UPDATE: Newer versions of ASP.NET/IIS may behave better than when I first wrote this.
UPDATE 2: If you are using ASP.NET MVC, add the following to web.config:
<?xml version="1.0"?>
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
</configuration>
According to my test,
implements OnItemClickListener -> works.
setOnItemClickListener -> works.
ListView is clickable by default (API 19)
The important thing is, "click" only works to TextView (if you choose simple_list_item_1.xml as item). That means if you provide text data for the ListView, "click" works when you click on text area. Click on empty area does not trigger "click event".

if not working in 4.0 then add:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Instead of String.IndexOf, use String.Equals to ensure you don't have partial matches. Also don't use FindAll as that goes through every element, use FindIndex (it stops on the first one it hits).
if(testList.FindIndex(x => x.Equals(keyword,
StringComparison.OrdinalIgnoreCase) ) != -1)
Console.WriteLine("Found in list");
Alternately use some LINQ methods (which also stops on the first one it hits)
if( testList.Any( s => s.Equals(keyword, StringComparison.OrdinalIgnoreCase) ) )
Console.WriteLine("found in list");
Version 2 of the API has been deprecated since March 2014, which some of these other answers are using.
Here is a very simple code snippet to get the views count from a video, using JQuery in the YouTube API v3.
You will need to create an API key via Google Developer Console first.
<script>
$.getJSON('https://www.googleapis.com/youtube/v3/videos?part=statistics&id=Qq7mpb-hCBY&key={{YOUR-KEY}}', function(data) {
alert("viewCount: " + data.items[0].statistics.viewCount);
});
</script>
Your problem arises because you're using a self signed key. The client does not trust this key, nor does the key itself provide a chain to validate or a certificate revocation list.
You have a few options - you can
turn off certificate validation on the client (bad move, man in the middle attacks abound)
use makecert to create a root CA and create certificates from that (ok move, but there is still no CRL)
create an internal root CA using Windows Certificate Server or other PKI solution then trust that root cert (a bit of a pain to manage)
purchase an SSL certificate from one of the trusted CAs (expensive)
My method of generating random number between 0 and n, where n <= 10 (n excluded):
Math.floor((Math.random() * 10) % n)
I don't see either MacPorts or Homebrew mentioned in other answers here, but since I do see them mentioned elsewhere on Stack Overflow for related questions, I'll add my own US$0.02 that many folks seem to consider MacPorts as not only a package manager for packages in general (as of today they list 16311 packages/ports, 2931 matching "python", albeit only for Macs), but also as a decent (maybe better) package manager for Python packages/modules:
"...what is the method that Mac python developers use to manage their modules?"
I'm still debating on whether or not to use MacPorts myself, but at the moment I'm leaning in that direction.
I think below link might help you -
If I'm understanding your question and code correctly, then I want to first mention three things before sharing my code/version of a solution. First, for both name
and value
you probably shouldn't be using the getAttribute()
method because they are, themselves, properties of (the variable named) inputs
(at a given index of i
). Secondly, the variable that you are trying to alert is one of a select handful of terms in JavaScript that are designated as 'reserved keywords' or simply "reserved words". As you can see in/on this list (on the link), new
is clearly a reserved word in JS and should never be used as a variable name. For more information, simply google 'reserved words in JavaScript'. Third and finally, in your alert statement itself, you neglected to include a semicolon. That and that alone can sometimes be enough for your code not to run as expected. [Aside: I'm not saying this as advice but more as observation: JavaScript will almost always forgive and allow having too many and/or unnecessary semicolons, but generally JavaScript is also equally if not moreso merciless if/when missing (any of the) necessary, required semicolons. Therefore, best practice is, of course, to add the semicolons only at all of the required points and exclude them in all other circumstances. But practically speaking, if in doubt, it probably will not hurt things by adding/including an extra one but will hurt by ignoring a mandatory one. General rules are all declarations and assignments end with a semicolon (such as variable assignments, alerts, console.log statements, etc.) but most/all expressions do not (such as for loops, while loops, function expressions Just Saying.] But I digress..
function whenWindowIsReady() {
var inputs = document.getElementsByTagName('input');
var lengthOfInputs = inputs.length; // this is for optimization
for (var i = 0; i < lengthOfInputs; i++) {
if (inputs[i].name === "ans") {
var ansIsName = inputs[i].value;
alert(ansIsName);
}
}
}
window.onReady = whenWindowIsReady();
PS: You used a double assignment operator in your conditional statement, and in this case it doesn't matter since you are comparing Strings, but generally I believe the triple assignment operator is the way to go and is more accurate as that would check if the values are EQUIVALENT WITHOUT TYPE CONVERSION, which can be very important for other instances of comparisons, so it's important to point out. For example, 1=="1" and 0==false are both true (when usually you'd want those to return false since the value on the left was not the same as the value on the right, without type conversion) but 1==="1" and 0===false are both false as you'd expect because the triple operator doesn't rely on type conversion when making comparisons. Keep that in mind for the future.
All good answers. To put it in simple language [BCNF] No partial key can depend on a key.
i.e No partial subset ( i.e any non trivial subset except the full set ) of a candidate key can be functionally dependent on some candidate key.
If your bound property is DateTime, then all you need is
Binding={Property, StringFormat=d}
Total online memory
Calculate the total online memory using the sys-fs.
totalmem=0;
for mem in /sys/devices/system/memory/memory*; do
[[ "$(cat ${mem}/online)" == "1" ]] \
&& totalmem=$((totalmem+$((0x$(cat /sys/devices/system/memory/block_size_bytes)))));
done
#one-line code
totalmem=0; for mem in /sys/devices/system/memory/memory*; do [[ "$(cat ${mem}/online)" == "1" ]] && totalmem=$((totalmem+$((0x$(cat /sys/devices/system/memory/block_size_bytes))))); done
echo ${totalmem} bytes
echo $((totalmem/1024**3)) GB
Example output for 4 GB system:
4294967296 bytes
4 GB
Explanation
/sys/devices/system/memory/block_size_bytes
Number of bytes in a memory block (hex value). Using 0x in front of the value makes sure it's properly handled during the calculation.
/sys/devices/system/memory/memory*
Iterating over all available memory blocks to verify they are online and add the calculated block size to totalmem if they are.
[[ "$(cat ${mem}/online)" == "1" ]] &&
You can change or remove this if you prefer another memory state.
