There could be another way to achieve what you want. Basically,
Then tar with the -T option which allows it to take a list of file locations (the one you just created with find!)
find . -name "*.whatever" > yourListOfFiles
tar -cvf yourfile.tar -T yourListOfFiles
I'm afraid that most voted solution (https://stackoverflow.com/a/19271434/3283279) is not working properly. The fourth test case (var_dump(validateDate('2012-2-25')); // false) is wrong. The date is correct, because it corresponds to the format - the m allows a month with or without leading zero (see: http://php.net/manual/en/datetime.createfromformat.php). Therefore a date 2012-2-25 is in format Y-m-d and the test case must be true not false.
I believe that better solution is to test possible error as follows:
function validateDate($date, $format = 'Y-m-d') {
DateTime::createFromFormat($format, $date);
$errors = DateTime::getLastErrors();
return $errors['warning_count'] === 0 && $errors['error_count'] === 0;
}
<textarea rows="4" cols="50"></textarea>
It is equivalent to:
textarea {
height: 4em;
width: 50em;
}
where 1em is equivalent to the current font size, thus make the text area 50 chars wide. see here.
If you have the element in scroll view then you can also solve this issue as :
<com.google.android.material.textfield.TextInputEditText
android:id="@+id/ed_password"
android:inputType="textPassword"
android:focusable="true"
android:imeOptions="actionNext"
android:nextFocusDown="@id/ed_confirmPassword" />
and in your activity:
edPassword.setOnEditorActionListener(new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT) {
focusOnView(scroll,edConfirmPassword);
return true;
}
return false;
}
});
public void focusOnView(ScrollView scrollView, EditText viewToScrollTo){
scrollView.post(new Runnable() {
@Override
public void run() {
scrollView.smoothScrollTo(0, viewToScrollTo.getBottom());
viewToScrollTo.requestFocus();
}
});
}
for n,line in enumerate(open("file")):
if "pattern" in line: print n+1
This is untested but will probably work.
In your .htaccess file put:
<Files ~ "\.html?$">
Header set Content-Type "text/html; charset=utf-8"
</Files>
However, this will require mod_headers on the server.
Use either of the two commands below. Everything must be in uppercase. The table name must be wrapped in quotation marks:
--SEE THE CONSTRAINTS ON A TABLE
SELECT COLUMN_NAME, CONSTRAINT_NAME FROM USER_CONS_COLUMNS WHERE TABLE_NAME = 'TBL_CUSTOMER';
--OR FOR LESS DETAIL
SELECT CONSTRAINT_NAME FROM USER_CONSTRAINTS WHERE TABLE_NAME = 'TBL_CUSTOMER';
For UTF 8 Conversion and Currency Symbol Export Use this:
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><?xml version="1.0" encoding="UTF-8" standalone="yes"?><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
, base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
return function(table, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
window.location.href = uri + base64(format(template, ctx))
}
})()
Try putting this HTML snippet into your served document:
<img id="ItemPreview" src="">
Then, on JavaScript side, you can dynamically modify image's src
attribute with so-called Data URL.
document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;
Alternatively, using jQuery:
$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);
This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..."
part) in the URL accordingly.

Use your console:
console.log(object);
Or if you are inspecting html dom elements use console.dir(object). Example:
let element = document.getElementById('alertBoxContainer');
console.dir(element);
Or if you have an array of js objects you could use:
console.table(objectArr);
If you are outputting a lot of console.log(objects) you can also write
console.log({ objectName1 });
console.log({ objectName2 });
This will help you label the objects written to console.
I know this is old but the ID's don't match in your code one is choose_pic and one is choose_pics:

I suspect you're facing the issue where your package.json
file is not in the same directory as your Gruntfile.js
. When you run your grunt xxx
commands, you get error an message like:
Local Npm module "xxx" not found. Is it installed?
For now, the solution is:
npm install
to load them locallyIMHO, it is sad that we cannot have grunt resolve modules loaded from a parent npm module (i.e. package.json in a parent directory within the same project). The discussion here seems to indicate that it was done to avoid loading "global" modules but I think what we want is loading from "my project" modules instead.
You mention the user switching between Activities pretty quickly. Could it be that you're calling unbindService
before the service connection has been established? This may have the effect of failing to unbind, then leaking the binding.
Not entirely sure how you could handle this... Perhaps when onServiceConnected
is called you could call unbindService
if onDestroy
has already been called. Not sure if that'll work though.
If you haven't already, you could add an onUnbind method to your service. That way you can see exactly when your classes unbind from it, and it might help with debugging.
@Override
public boolean onUnbind(Intent intent) {
Log.d(this.getClass().getName(), "UNBIND");
return true;
}
Hello I got the best solution of this, suppose if u have to hide a particular item at on create Menu method and show that item in other fragment. I am taking an example of two menu item one is edit and other is delete. e.g menu xml is as given below:
sell_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_edit"
android:icon="@drawable/ic_edit_white_shadow_24dp"
app:showAsAction="always"
android:title="Edit" />
<item
android:id="@+id/action_delete"
android:icon="@drawable/ic_delete_white_shadow_24dp"
app:showAsAction="always"
android:title="Delete" />
Now Override the two method in your activity & make a field variable mMenu as:
private Menu mMenu; // field variable
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.sell_menu, menu);
this.mMenu = menu;
menu.findItem(R.id.action_delete).setVisible(false);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.action_delete) {
// do action
return true;
} else if (item.getItemId() == R.id.action_edit) {
// do action
return true;
}
return super.onOptionsItemSelected(item);
}
Make two following method in your Activity & call them from fragment to hide and show your menu item. These method are as:
public void showDeleteImageOption(boolean status) {
if (menu != null) {
menu.findItem(R.id.action_delete).setVisible(status);
}
}
public void showEditImageOption(boolean status) {
if (menu != null) {
menu.findItem(R.id.action_edit).setVisible(status);
}
}
That's Solve from my side,I think this explanation will help you.

Ok, I know I'm late to the party, but here is the syntax I think is best. Add a schema name if needed to the OBJECT_ID clause.
IF OBJECTPROPERTY(OBJECT_ID(N'My_FK_name'),'IsConstraint') =1
ALTER TABLE dbo.TableName DROP CONSTRAINT My_FK_name
Create a stored procedure that does something like the following:
declare @startDate date;
declare @endDate date;
select @startDate = '20150528';
select @endDate = '20150531';
with dateRange as
(
select dt = dateadd(dd, 1, @startDate)
where dateadd(dd, 1, @startDate) < @endDate
union all
select dateadd(dd, 1, dt)
from dateRange
where dateadd(dd, 1, dt) < @endDate
)
select *
from dateRange
Or better still create a calendar table and just select from that.
numpy's genfromtxt or loadtxt is what I use:
import numpy as np
...
wordset = np.genfromtxt(fname='words.txt')
This got me headed in the right direction and solved my problem.
There is also read_csv
in Pandas, which is fast and supports non-comma column separators and automatic typing by column:
import pandas as pd
df = pd.read_csv('your_file',sep='\t')
It can be converted to a NumPy array if you prefer that type with:
import numpy as np
arr = np.array(df)
This is by far the easiest and most mature text import approach I've come across.

There's no fast way to retrieve attributes. But code ought to look like this (credit to Aaronaught):
var t = typeof(YourClass);
var pi = t.GetProperty("Id");
var hasIsIdentity = Attribute.IsDefined(pi, typeof(IsIdentity));
If you need to retrieve attribute properties then
var t = typeof(YourClass);
var pi = t.GetProperty("Id");
var attr = (IsIdentity[])pi.GetCustomAttributes(typeof(IsIdentity), false);
if (attr.Length > 0) {
// Use attr[0], you'll need foreach on attr if MultiUse is true
}
To reference range of cells you can use Range(Cell1,Cell2), sample:
Sub RangeTest()
Dim testRange As Range
Dim targetWorksheet As Worksheet
Set targetWorksheet = Worksheets("MySheetName")
With targetWorksheet
.Cells(5, 10).Select 'selects cell J5 on targetWorksheet
Set testRange = .Range(.Cells(5, 5), .Cells(10, 10))
End With
testRange.Select 'selects range of cells E5:J10 on targetWorksheet
End Sub

I had the same issue with testing activity in my Android app. I used ActivityInstrumentationTestCase2
and MockitoAnnotations.initMocks(this);
didn't work.
I solved this issue with another class with respectively field. For example:
class CaptorHolder {
@Captor
ArgumentCaptor<Callback<AuthResponse>> captor;
public CaptorHolder() {
MockitoAnnotations.initMocks(this);
}
}
Then, in activity test method:
HubstaffService hubstaffService = mock(HubstaffService.class);
fragment.setHubstaffService(hubstaffService);
CaptorHolder captorHolder = new CaptorHolder();
ArgumentCaptor<Callback<AuthResponse>> captor = captorHolder.captor;
onView(withId(R.id.signInBtn))
.perform(click());
verify(hubstaffService).authorize(anyString(), anyString(), captor.capture());
Callback<AuthResponse> callback = captor.getValue();

1.Add a another view controller in “didFinishLaunchingWithOptions”
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UINavigationController *homeNav = [storyboard instantiateViewControllerWithIdentifier:@"NavigationControllerView"];
UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"SplashViewController"];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = homeNav;
[self.window makeKeyAndVisible];
[(UINavigationController *)self.window.rootViewController pushViewController:viewController animated:NO];
}
2.In view did load of SplashView Controller
[self performSelector:@selector(removeSplashScreenAddViewController) withObject:nil afterDelay:2.0];
3.In removeSplashScreenAddViewController method you can add your main view controller for eg.-
- (void) removeSplashScreenAddViewController {` UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UINavigationController *homeNav = [storyboard instantiateViewControllerWithIdentifier:@"HomeNav"];
UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:viewControllerName];
UIWindow *window = [StaticHelper mainWindow];
window.rootViewController = homeNav;
[window makeKeyAndVisible];
[(UINavigationController *)window.rootViewController pushViewController:viewController animated:NO];`}

First off, your quoted code is not JSON. Your code is JavaScript object literal notation. JSON is a subset of that designed for easier parsing.
Your code defines an object (data
) containing an array (items
) of objects (each with an id
, name
, and type
).
You don't need or want jQuery for this, just JavaScript.
Adding an item:
data.items.push(
{id: "7", name: "Douglas Adams", type: "comedy"}
);
That adds to the end. See below for adding in the middle.
Removing an item:
There are several ways. The splice
method is the most versatile:
data.items.splice(1, 3); // Removes three items starting with the 2nd,
// ("Witches of Eastwick", "X-Men", "Ordinary People")
splice
modifies the original array, and returns an array of the items you removed.
Adding in the middle:
splice
actually does both adding and removing. The signature of the splice
method is:
removed_items = arrayObject.splice(index, num_to_remove[, add1[, add2[, ...]]]);
index
- the index at which to start making changesnum_to_remove
- starting with that index, remove this many entriesaddN
- ...and then insert these elementsSo I can add an item in the 3rd position like this:
data.items.splice(2, 0,
{id: "7", name: "Douglas Adams", type: "comedy"}
);
What that says is: Starting at index 2, remove zero items, and then insert this following item. The result looks like this:
var data = {items: [
{id: "1", name: "Snatch", type: "crime"},
{id: "2", name: "Witches of Eastwick", type: "comedy"},
{id: "7", name: "Douglas Adams", type: "comedy"}, // <== The new item
{id: "3", name: "X-Men", type: "action"},
{id: "4", name: "Ordinary People", type: "drama"},
{id: "5", name: "Billy Elliot", type: "drama"},
{id: "6", name: "Toy Story", type: "children"}
]};
You can remove some and add some at once:
data.items.splice(1, 3,
{id: "7", name: "Douglas Adams", type: "comedy"},
{id: "8", name: "Dick Francis", type: "mystery"}
);
...which means: Starting at index 1, remove three entries, then add these two entries. Which results in:
var data = {items: [
{id: "1", name: "Snatch", type: "crime"},
{id: "7", name: "Douglas Adams", type: "comedy"},
{id: "8", name: "Dick Francis", type: "mystery"},
{id: "4", name: "Ordinary People", type: "drama"},
{id: "5", name: "Billy Elliot", type: "drama"},
{id: "6", name: "Toy Story", type: "children"}
]};
I haven't used jQuery, but in a library like Prototype you can bind functions to a specific scope. So with that in mind your code would look like this:
$('#foobar').ready('click', this.doSomething.bind(this));
The bind method returns a new function that calls the original method with the scope you have specified.
Both of your examples should behave pretty much the same.
A value returned inside a then()
handler becomes the resolution value of the promise returned from that then()
. If the value returned inside the .then
is a promise, the promise returned by then()
will "adopt the state" of that promise and resolve/reject just as the returned promise does.
In your first example, you return "bbb"
in the first then()
handler, so "bbb"
is passed into the next then()
handler.
In your second example, you return a promise that is immediately resolved with the value "bbb"
, so "bbb"
is passed into the next then()
handler. (The Promise.resolve()
here is extraneous).
The outcome is the same.
If you can show us an example that actually exhibits different behavior, we can tell you why that is happening.
First, let me fix a little bit your declaration:
List<Map<String, List<String>>> listOfMapOfList =
new HashList<Map<String, List<String>>>();
Please pay attention that I used concrete class (HashMap
) only once. It is important to use interface where you can to be able to change the implementation later.
Now you want to add element to the list, don't you? But the element is a map, so you have to create it:
Map<String, List<String>> mapOfList = new HashMap<String, List<String>>();
Now you want to populate the map. Fortunately you can use utility that creates lists for you, otherwise you have to create list separately:
mapOfList.put("mykey", Arrays.asList("one", "two", "three"));
OK, now we are ready to add the map into the list:
listOfMapOfList.add(mapOfList);
BUT:
Stop creating complicated collections right now! Think about the future: you will probably have to change the internal map to something else or list to set etc. This will probably cause you to re-write significant parts of your code. Instead define class that contains you data and then add it to one-dimentional collection:
Let's call your class Student
(just as example):
public Student {
private String firstName;
private String lastName;
private int studentId;
private Colectiuon<String> courseworks = Collections.emtpyList();
//constructors, getters, setters etc
}
Now you can define simple collection:
Collection<Student> students = new ArrayList<Student>();
If in future you want to put your students into map where key is the studentId
, do it:
Map<Integer, Student> students = new HashMap<Integer, Student>();
(Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name BuildLabEx).BuildLabEx
Auto reload with target of your choice. In this case target is _self
set to every 5 minutes.
300000 milliseconds = 300 seconds = 5 minutes
as 60000 milliseconds = 60 seconds = 1 minute.
This is how you do it:
<script type="text/javascript">
function load()
{
setTimeout("window.open('http://YourPage.com', '_self');", 300000);
}
</script>
<body onload="load()">
Or this if it is the same page to reload itself:
<script type="text/javascript">
function load()
{
setTimeout("window.open(self.location, '_self');", 300000);
}
</script>
<body onload="load()">
Actually you can fix it with following steps -
cls.__dict__
{'isFilled':True}
or {'isFilled':False}
depending upon what you have set.del cls.__dict__['isFilled']
In this case, we delete the entry which overrides the method as mentioned by BrenBarn.
If you're only getting these to manually pass into df.set_index()
, that's unnecessary. Just directly do df.set_index['your_col_name', drop=False]
, already.
It's very rare in pandas that you need to get an index as a Python list (unless you're doing something pretty funky, or else passing them back to NumPy), so if you're doing this a lot, it's a code smell that you're doing something wrong.
Trying to access an undefined variable will throw you a ReferenceError
.
A solution to this is to use typeof
:
if (typeof window === "undefined") {
console.log("Oops, `window` is not defined")
}
or a try catch:
try { window } catch (err) {
console.log("Oops, `window` is not defined")
}
While typeof window
is probably the cleanest of the two, the try catch can still be useful in some cases.
Use the command dir
to list all the directories and files in a directory; ls
is a unix command.
void main ()
{
int temp,integer,count=0,i,cnd=0;
char ascii[10]={0};
printf("enter a number");
scanf("%d",&integer);
if(integer>>31)
{
/*CONVERTING 2's complement value to normal value*/
integer=~integer+1;
for(temp=integer;temp!=0;temp/=10,count++);
ascii[0]=0x2D;
count++;
cnd=1;
}
else
for(temp=integer;temp!=0;temp/=10,count++);
for(i=count-1,temp=integer;i>=cnd;i--)
{
ascii[i]=(temp%10)+0x30;
temp/=10;
}
printf("\n count =%d ascii=%s ",count,ascii);
}
A local variable is memory on the stack, that memory is not automatically invalidated when you go out of scope. From a Function deeper nested (higher on the stack in memory), its perfectly safe to access this memory.
Once the Function returns and ends though, things get dangerous. Usually the memory is not deleted or overwritten when you return, meaning the memory at that adresss is still containing your data - the pointer seems valid.
Until another function builds up the stack and overwrites it. This is why this can work for a while - and then suddenly cease to function after one particularly deeply nested set of functions, or a function with really huge sized or many local objects, reaches that stack-memory again.
It even can happen that you reach the same program part again, and overwrite your old local function variable with the new function variable. All this is very dangerous and should be heavily discouraged. Do not use pointers to local objects!
This is what I usually need in a script/function:
while true; do
read -p "Continue [Y/n]? " -n 1 -r -e yn
case "${yn:-Y}" in
[YyZzOoJj]* ) echo; break ;;
[Nn]* ) [[ "$0" = "$BASH_SOURCE" ]] && exit 1 || return 1 ;; # handle exits from shell or function but don't exit interactive shell
* ) echo "Please answer yes or no.";;
esac
done
echo "and off we go!"
The selected answer didn't work for me, but it's close. I found a tutorial that worked for me and the certificate I obtained from StartCom.
Change the leader and trailer so the file looks similar to this:
-----BEGIN PKCS7-----
[... certificate content here ...]
-----END PKCS7-----
For example, my StartCom certificate began with:
-----BEGIN CERTIFICATE-----
and ended with:
-----END CERTIFICATE-----
Run the following OpenSSL command (works on Ubuntu 14.04.4, as of this writing):
openssl pkcs7 -print_certs –in pkcs7.p7b -out pem.cer
The output is a .cer with the certificate chain.

While making such conversions one should take into consideration the behavior of timezones while converting from one object to the other. I found some good notes and examples in this stackoverflow post.
Granted, OP stated very similarly that this didn't work, but it did for me. Based on the notes in my source, it seems it was implemented around the time, or after, OP's post. Perhaps it's more standard now.
document.getElementsByName('MyElementsName')[0].click();
In my case, my button didn't have an ID. If your element has an id, preferably use the following (untested).
document.getElementById('MyElementsId').click();
I originally tried this method and it didn't work. After Googling I came back and realized my element was by name, and didn't have an ID. Double check you're calling the right attribute.
Source: https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click
Try the following, note that when user refreshes the page, the value is "Male" again, data should be stored on database.
<p id="pTest">Male</p>
<button>change</button>
<script>
$('button').click(function(){
$('#pTest').text('test')
})
</script>
I really like Tovask's answer but it doesn't work due to the function having the name download
(this answer explains why). I also don't see the point in replacing "data:image/..." with "data:application/...".
The following code has been tested in Chrome and Firefox and seems to work fine in both.
JavaScript:
function prepDownload(a, canvas, name) {
a.download = name
a.href = canvas.toDataURL()
}
HTML:
<a href="#" onclick="prepDownload(this, document.getElementById('canvasId'), 'imgName.png')">Download</a>
<canvas id="canvasId"></canvas>
if (mysql_num_rows($result)==0) { PERFORM ACTION }
For PHP 5 and 7 and above use mysqli:
if (mysqli_num_rows($result)==0) { PERFORM ACTION }
This gets my vote.
OP assuming query is not returning any error, so this should be one of the way
For debugging purposes in case you want to look up a raw Mat::type in a debugger:
+--------+----+----+----+----+------+------+------+------+
| | C1 | C2 | C3 | C4 | C(5) | C(6) | C(7) | C(8) |
+--------+----+----+----+----+------+------+------+------+
| CV_8U | 0 | 8 | 16 | 24 | 32 | 40 | 48 | 56 |
| CV_8S | 1 | 9 | 17 | 25 | 33 | 41 | 49 | 57 |
| CV_16U | 2 | 10 | 18 | 26 | 34 | 42 | 50 | 58 |
| CV_16S | 3 | 11 | 19 | 27 | 35 | 43 | 51 | 59 |
| CV_32S | 4 | 12 | 20 | 28 | 36 | 44 | 52 | 60 |

So for example, if type = 30 then OpenCV data type is CV_64FC4. If type = 50 then the OpenCV data type is CV_16UC(7).
The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.
When working to create Cross Browser Favicons (including touch icons) there are several things to consider.
The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon"
for IE to recognize the icon it needs the word shortcut
which is not standard. Also we wrap the .ico
favicon in a IE conditional comment because Chrome and Safari will use the .ico
file if it is present, despite other options available, not what we would like.
The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.
For the rest of the browsers we are going to use the standard way to cite a favicon:
<link rel="icon" href="path/to/favicon.png">
This icon should be 196x196 pixels in size to cover all devices that may use this icon.
To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
Using rel="apple-touch-icon-precomposed"
will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon"
. This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed"
.
As a note: Chrome for Android states:
The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).
Custom Tiles for IE 11+ on Windows 8.1+
IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.
Microsoft recommends creating a few tiles at the following size:
Small: 128 x 128
Medium: 270 x 270
Wide: 558 x 270
Large: 558 x 558
These should be transparent images as we will define a color background next.
Once these images are created you should create an xml file called browserconfig.xml
with the following code:
<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
<msapplication>
<tile>
<square70x70logo src="images/smalltile.png"/>
<square150x150logo src="images/mediumtile.png"/>
<wide310x150logo src="images/widetile.png"/>
<square310x310logo src="images/largetile.png"/>
<TileColor>#009900</TileColor>
</tile>
</msapplication>
</browserconfig>
Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head
:
<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />
For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.
Putting it all together:
To put it all together the above code would look like this:
<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. -->
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">
Windows Phone Live Tiles
If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:
Here are detailed instructions from Microsoft but here is a synopsis:
Step 1
Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.
Step 2
Add a hidden overlay of this image. Here is example code from Microsoft:
<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
<img src="customtile.png" width="320" height="320" />
<div style='margin-top: 40px'>
Add text/graphic asking user to pin to start using the menu...
</div>
</div>
Step 3
You then can add thew following line to add a pin to start link:
<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>
Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.
Step 4
Next you add some JS to toggle the overlay visibility
<script>
function ToggleTileOverlay() {
var newVisibility = (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
document.getElementById('TileOverlay').style.visibility = newVisibility;
}
</script>
Note on Sizes
I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.
Further Reading
For those who would like more details see the links below:
In objective C variables with no value were equal to 'nil'(it was also possible to use 'nil' values same as 0 and false), hence it was possible to use variables in conditional statements (Variables having values are same as 'TRUE' and those with no values were equal to 'FALSE').
Swift provides type safety by providing 'optional value'. i.e. It prevents errors formed from assigning variables of different types.
So in Swift, only booleans can be provided on conditional statements.
var hw = "Hello World"
Here, even-though 'hw' is a string, it can't be used in an if statement like in objective C.
//This is an error
if hw
{..}
For that it needs to be created as,
var nhw : String? = "Hello World"
//This is correct
if nhw
{..}
I created these functions based on Joey Guerra's suggestion, thank you for that. I'm elaborating a little bit, perhaps someone can use it. The first function checkDefaults() is called when an input changes, the second is called when the form is submitted using jQuery.post. div.updatesubmit is my submit button, and class 'needsupdate' is an indicator that an update is made but not yet submitted.
function checkDefaults() {
var changed = false;
jQuery('input').each(function(){
if(this.defaultValue != this.value) {
changed = true;
}
});
if(changed === true) {
jQuery('div.updatesubmit').addClass("needsupdate");
} else {
jQuery('div.updatesubmit').removeClass("needsupdate");
}
}
function renewDefaults() {
jQuery('input').each(function(){
this.defaultValue = this.value;
});
jQuery('div.updatesubmit').removeClass("needsupdate");
}
I had the same error. Make sure you don't have any <input>
, <select>
, etc. name="location"
.
None of the answers seemed to work for me or were too complicated. Luckily, it's not complicated with xargs
(Tested on Ubuntu 20.04).
This works with each arg on a separate line in the file as the OP mentions and was what I needed as well.
cat foo.txt | xargs my_command
One thing to note is that it doesn't seem to work with aliased commands.
The accepted answer works if the command accepts multiple args wrapped in a string. In my case using (Neo)Vim it does not and the args are all stuck together.
xargs
does it probably and actually gives you separate arguments supplied to the command.
You can also use while loop
IFS=,
while read name val; do
echo "............................"
echo Name: "$name"
done<itemlst.csv
On Mac OS X Yosemite just install:
Java SE Development Kit 8
and
Java Version 8 Update 25
It's all, work for me!
The way I see it, the only place for a nested query would be in the WHERE clause, so e.g.
SELECT country.name, country.headofstate
FROM country
WHERE country.headofstate LIKE 'A%' AND
country.id in (SELECT country_id FROM city WHERE population > 100000)
Apart from that, I have to agree with Adrian on: why the heck should you use nested queries?
For Linux/Ubuntu
Create a new File from Terminal as
gedit emulator.sh (Use any Name for file here i have used "emulator")
now write following lines in this file
cd /home/userName/Android/Sdk/tools/
./emulator @your created Android device Name
(here after @ write the name of your AVD e.g
./emulator @Nexus_5X_API_27 )
Now save the file and run your emulator using following commands
./emulator.sh
In case of Permission denied use following command before above command
chmod +x emulator.sh
All set Go..
You can, of course, show it before making the request, and hide it after it completes:
$('#loading-image').show();
$.ajax({
url: uri,
cache: false,
success: function(html){
$('.info').append(html);
},
complete: function(){
$('#loading-image').hide();
}
});
I usually prefer the more general solution of binding it to the global ajaxStart and ajaxStop events, that way it shows up for all ajax events:
$('#loading-image').bind('ajaxStart', function(){
$(this).show();
}).bind('ajaxStop', function(){
$(this).hide();
});
Use toString() when you want to present information to a user (including a developer looking at a log). Never rely in your code on toString()
giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString()
return, then it was already broken.
If you need to get the exact name used to declare the enum constant, you should use name() as toString
may have been overridden.
I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));
while ((line = br.readLine()) != null) {
}
I hope this can help anyone who sees this post.
As byte[] is mutable it is treated as only being .equals()
if its the same object.
If you want to compare the contents you have to use Arrays.equals(a, b)
BTW: Its not the way I would design it. ;)

Just for completeness: Stream solution since Java 8.

I think I sticked with the System.arraycopy()
in your situtation. But the best long-term solution might be to convert everything to Immutable Collections (Guava, Vavr), as long as those collections are short-lived.

As scoota269 says, you should use onSubmit
instead, cause pressing enter on a textbox will most likey trigger a form submit (if inside a form)
<form action="#" onsubmit="handle">
<input type="text" name="txt" />
</form>
<script>
function handle(e){
e.preventDefault(); // Otherwise the form will be submitted
alert("FORM WAS SUBMITTED");
}
</script>
If you want to have an event on the input-field then you need to make sure your handle()
will return false, otherwise the form will get submitted.
<form action="#">
<input type="text" name="txt" onkeypress="handle(event)" />
</form>
<script>
function handle(e){
if(e.keyCode === 13){
e.preventDefault(); // Ensure it is only this code that runs
alert("Enter was pressed was presses");
}
}
</script>

A simple example without classes:
from tkinter import *

If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
"start" is a name of a script, in npm you run scripts like this npm run scriptName
, npm start
is also a short for npm run start
As for "react-scripts" this is a script related specifically to create-react-app
I have used ndk.dir=/usr/shareData/android-ndk-r11b
// path of ndk
in local.properties file in android studio project. and
add this line :

The fastest code for counting files with ANY attributes in folder %FOLDER%
and its subfolders is the following. The code is for script in a command script (batch) file.
@for /f %%a in ('2^>nul dir "%FOLDER%" /a-d/b/-o/-p/s^|find /v /c ""') do set n=%%a
@echo Total files: %n%.
You made a simple mistake. Don't worry....
Simply use getElementById
instead getElementsById
true
var first_number = parseInt(document.getElementById("Text1").value);
False
var first_number = parseInt(document.getElementsById("Text1").value);
Thanks ...
var
just tells the compiler to infer the type you wanted at compile time...it cannot infer from null
(though there are cases it could).
So, no you are not allowed to do this.
When you say "some empty value"...if you mean:
var s = string.Empty;
//
var s = "";
Then yes, you may do that, but not null
.
var res = exitDictionary
.Select(p => p.Value).Cast<Dictionary<string, object>>()
.SelectMany(d => d)
.Where(p => p.Key == "fieldname1")
.Select(p => p.Value).Cast<List<Dictionary<string,string>>>()
.SelectMany(l => l)
.SelectMany(d=> d)
.Where(p => p.Key == "valueTitle")
.Select(p => p.Value)
.ToList();
This also works, and easy to understand.
You can use phpseclib pollyfill package. You can not use open ssl or libsodium for encrypt/decrypt with rijndael 256. Another issue, you don't need replacement any code.
I would suggest you just evenly space them as shown in this answer here
.navbar ul {
list-style-type: none;
padding: 0;
display: flex;
flex-direction: row;
justify-content: space-around;
flex-wrap: nowrap; /* assumes you only want one row */
}
Try configuration at /config/application.rb:
config.middleware.insert_before 0, "Rack::Cors" do
allow do
origins '*'
resource '*', :headers => :any, :methods => [:get, :post, :options, :delete, :put, :patch], credentials: true
end
end
I would do something like
$('td').find('a').each(function(){
$(this).addClass('disabled-link');
});
$('.disabled-link').on('click', false);
something like this should work. You add a class for links you want to have disabled and then you return false when someone click them. To enable them just remove the class.
In my case it was a failed import to eclipse. I had to delete the project from eclipse (without deleting form the filesystem of course) and reimport it. After that the error was gone immediately.
This has nothing to do with using PDO, it's just that you are confusing INSERT and UPDATE.
Here's the difference:
INSERT
creates a new row. I'm guessing that you really want to create a new row.UPDATE
changes the values in an existing row, but if this is what you're doing you probably should use a WHERE clause to restrict the change to a specific row, because the default is that it applies to every row.So this will probably do what you want:
$sql = "INSERT INTO `access_users`
(`contact_first_name`,`contact_surname`,`contact_email`,`telephone`)
VALUES (:firstname, :surname, :email, :telephone);
";
Note that I've also changed the order of columns; the order of your columns must match the order of values in your VALUES clause.
MySQL also supports an alternative syntax for INSERT:
$sql = "INSERT INTO `access_users`
SET `contact_first_name` = :firstname,
`contact_surname` = :surname,
`contact_email` = :email,
`telephone` = :telephone
";
This alternative syntax looks a bit more like an UPDATE statement, but it creates a new row like INSERT. The advantage is that it's easier to match up the columns to the correct parameters.
Try a different encoding such as Encoding.UTF8. You can also try letting StreamReader find the encoding itself:
StreamReader reader = new StreamReader(inputFilePath, System.Text.Encoding.UTF8, true)
Edit: Just saw your update. Try letting StreamReader do the guessing.
you could try in this way: get the integer value of the double, subtract this from the original double value, define a rounding range and tests if the absolute number of the new double value(without the integer part) is larger or smaller than your defined range. if it is smaller you can intend it it is an integer value. Example:
public final double testRange = 0.2;
public static boolean doubleIsInteger(double d){
int i = (int)d;
double abs = Math.abs(d-i);
return abs <= testRange;
}
If you assign to d the value 33.15 the method return true. To have better results you can assign lower values to testRange (as 0.0002) at your discretion.
There are many excellent answers to this question, including the important use cases of forward declarations, polymorphism etc. but I feel a part of the "soul" of your question is not answered - namely what the different syntaxes mean across Java and C++.
Let's examine the situation comparing the two languages:
Object object1 = new Object(); //A new object is allocated by Java
Object object2 = new Object(); //Another new object is allocated by Java
object1 = object2;
//object1 now points to the object originally allocated for object2
//The object originally allocated for object1 is now "dead" - nothing points to it, so it
//will be reclaimed by the Garbage Collector.
//If either object1 or object2 is changed, the change will be reflected to the other
The closest equivalent to this, is:
Object * object1 = new Object(); //A new object is allocated on the heap
Object * object2 = new Object(); //Another new object is allocated on the heap
delete object1;
//Since C++ does not have a garbage collector, if we don't do that, the next line would
//cause a "memory leak", i.e. a piece of claimed memory that the app cannot use
//and that we have no way to reclaim...
object1 = object2; //Same as Java, object1 points to object2.
Let's see the alternative C++ way:
Object object1; //A new object is allocated on the STACK
Object object2; //Another new object is allocated on the STACK
object1 = object2;//!!!! This is different! The CONTENTS of object2 are COPIED onto object1,
//using the "copy assignment operator", the definition of operator =.
//But, the two objects are still different. Change one, the other remains unchanged.
//Also, the objects get automatically destroyed once the function returns...
The best way to think of it is that -- more or less -- Java (implicitly) handles pointers to objects, while C++ may handle either pointers to objects, or the objects themselves. There are exceptions to this -- for example, if you declare Java "primitive" types, they are actual values that are copied, and not pointers. So,
int object1; //An integer is allocated on the stack.
int object2; //Another integer is allocated on the stack.
object1 = object2; //The value of object2 is copied to object1.
That said, using pointers is NOT necessarily either the correct or the wrong way to handle things; however other answers have covered that satisfactorily. The general idea though is that in C++ you have much more control on the lifetime of the objects, and on where they will live.
Take home point -- the Object * object = new Object()
construct is actually what is closest to typical Java (or C# for that matter) semantics.
RGB values fall nicely on bit boundaries; decimal digits don't. I don't think there's an easy way to do this using bitwise operators at all. You'd need to use decimal operators like modulo 10 (% 10).
I think by combining .children() with $(this) will return the children of the selected item only
consider the following:
$("div li").click(function() {
$(this).children().css('background','red');
});
this will change the background of the clicked li only
@echo off

)
Step1: above lines copy into note pad save it as bat.
step2: In d drive abc folder in all Sql files in queries executed in sql server.
step3: Give your ip, user id and password.
I see everyone saying how to fix it with strange copying etc, but no one really said why the problem occurs.
So let me explain, for those of you who like me don't want to mess with system files only because someone on SO told them so.
The problem is that:

python-apt
/python3-apt
is a system package, so it's for default system pythonThus, the scripts will always get the version currently linked to python3
, but fail because the apt package is not present.
General solution: NEVER change default python3
link. Ever. This also applies to python
link - if an app was written in Python2 with some old syntax elements that don't work in Python3, the app will not work.
[My terminal broke that way because I use Terminator, which is apparently written in Python2.7 not compatible with Python3.]
Solutions presented here either suggest copying/linking the apt package files or changing python3
link.
Let's analyse both:
This shouldn't be a problem because from around Python3.4 all python scripts work on newer versions as well.
So far. But it may break in the future - if you keep your system long enough.
python3
link backThis is a great solution because we can get back to "never ever changing the link"
"But I like having to type just python
!" - I like it too! That's how I got to this problem in the first place!
In general, you should avoid manually changing system links - use update-alternatives
instead to link different versions. This applies to any app with many versions. This will still break those system scripts (because it does change the link), but you can switch back and forth easily, without worrying whether you put link and dest in the right order or made a typo.
Consider using other name than python
/python3
for your link or alias.
Or add your own python
/python3
link to PATH (just like virtual environments do), without changing system links.
If you have a typo in your branchname you'll get this same error.
+=
is just a shortcut for writing
number = 4
number = number + 1
So instead you would write
numbers = 4
numbers += 1
Both ways are correct but example two helps you write a little less code
Try this.
var lines = $('textarea').val().split('\n');
for(var i = 0;i < lines.length;i++){
//code here using lines[i] which will give you each line
}
Below solution worked for me -
1- Go to project directory
2- run mvn eclipse:eclipse (Hope mvn is added in your path)
3- run mvn clean install
Refresh your project in Eclipse and check.
Try this query
DECLARE @PrintVarchar nvarchar(max) = (Select Sum(Amount) From Expense)
PRINT 'Varchar format =' + @PrintVarchar
DECLARE @PrintInt int = (Select Sum(Amount) From Expense)
PRINT @PrintInt
>>> def create_generator():
... my_list = range(3)
... for i in my_list:
... yield i*i
...
>>> my_generator = create_generator() # create a generator
>>> print(my_generator) # my_generator is an object!
<generator object create_generator at 0xb7555c34>
>>> for i in my_generator:
... print(i)
0

In short, you can see that the loop does not stop and continues to function even after the object or variable is sent (unlike return
where the loop stops after execution).
/**
* Assigns the specified char value to each element of the specified array
* of chars.
*
* @param a the array to be filled
* @param val the value to be stored in all elements of the array
*/
public static void fill(char[] a, char val) {
for (int i = 0, len = a.length; i < len; i++)
a[i] = val;
}
That's the way Arrays.fill does it.
(I suppose you could drop into JNI and use memset
.)
Use chardet https://github.com/chardet/chardet (documentation is short and easy to read).
Install python, then pip install chardet, at last use the command line command.
I tested under GB2312 and it's pretty accurate. (Make sure you have at least a few characters, sample with only 1 character may fail easily).
file
is not reliable as you can see.
Add image in repository from upload file option then in README file
![Alt text]("enter image url of repositoryhere")
Call JObject's ToString(Formatting.None)
method.
Alternatively if you pass the object to the JsonConvert.SerializeObject method it will return the JSON without formatting.
Documentation: Write JSON text with JToken.ToString
Button button = new Button();
button.Click += (s,e) => { your code; };
//button.Click += new EventHandler(button_Click);
container.Controls.Add(button);
//protected void button_Click (object sender, EventArgs e) { }
Since Java 1.6, there is ArrayDeque
, which implements Queue
and seems to be faster and more memory efficient than a LinkedList
and doesn't have the thread synchronization overhead of the ArrayBlockingQueue
: from the API docs: "This class is likely to be faster than Stack when used as a stack, and faster than LinkedList when used as a queue."
final Queue<Object> q = new ArrayDeque<Object>();
q.add(new Object()); //insert element
q.poll(); //remove element
You need add -> contentType: "application/json; charset=utf-8",
<script type="text/javascript">
$(document).ready( function() {
$('#btnTest').click( function() {
$.ajax({
type: "POST",
url: "/Login/Test",
data: { ListID: '1', ItemName: 'test' },
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(response) { alert(response); },
error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); }
});
});
});
</script>
Can a relational database input latitudes and longitudes of places and roads, and compute the shortest path between them - no. This is one problem that shows SQL is not Turing complete.
But C++ can do it, and can do any problem. Thus it is.
Another suggestion, which was the solution for me: I got the error in the line
<resources xmlns:ns1="http://schemas.android.com/tools" xmlns:ns2="urn:oasis:names:tc:xliff:document:1.2">
in the values.xml file that was automatically generated during the build process.
It was solved by adding the android
prefix in the styles.xml file.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

had to be changed to

* The cost to add or delete an element into a known location in the list
(i.e. if you have an iterator to the location) is O(1). If you don't
know the location, then you need to traverse the list to the location
of deletion/insertion, which takes O(n) time.
** The deletion cost is O(log n) for the minimum or maximum, O(n) for an
arbitrary element.
BaileyP's answer is already pretty good, but I would use this condition instead:
if(function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc() === 1){
$_POST = array_map( 'stripslashes', $_POST );
$_GET = array_map( 'stripslashes', $_GET );
$_COOKIE = array_map( 'stripslashes', $_COOKIE );
}
It is more defensive.
Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.
Here's my little class that can reprint blocks of text. It properly clears the previous text so you can overwrite your old text with shorter new text without creating a mess.
import re, sys
class Reprinter:
def __init__(self):
self.text = ''
def moveup(self, lines):
for _ in range(lines):
sys.stdout.write("\x1b[A")
def reprint(self, text):
# Clear previous text by overwritig non-spaces with spaces
self.moveup(self.text.count("\n"))
sys.stdout.write(re.sub(r"[^\s]", " ", self.text))
# Print new text
lines = min(self.text.count("\n"), text.count("\n"))
self.moveup(lines)
sys.stdout.write(text)
self.text = text
reprinter = Reprinter()
reprinter.reprint("Foobar\nBazbar")
reprinter.reprint("Foo\nbar")
You could use a combination of the UNIX_TIMESTAMP() function to do that.
SELECT ... FROM ... WHERE UNIX_TIMESTAMP() - UNIX_TIMESTAMP(thefield) < 259200
ls -lh file.txt | awk '{ print $5 }'
Chosen API has changed a lot.
If non of the solution given works for you, you can try this one: https://github.com/goFrendiAsgard/gofrendi.chosen.ajaxify
Here is the function:
// USAGE:
// $('#some_input_id').chosen();
// chosen_ajaxify('some_input_id', 'http://some_url.com/contain/');
// REQUEST WILL BE SENT TO THIS URL: http://some_url.com/contain/some_term
// AND THE EXPECTED RESULT (WHICH IS GOING TO BE POPULATED IN CHOSEN) IS IN JSON FORMAT
// CONTAINING AN ARRAY WHICH EACH ELEMENT HAS "value" AND "caption" KEY. EX:
// [{"value":"1", "caption":"Go Frendi Gunawan"}, {"value":"2", "caption":"Kira Yamato"}]
function chosen_ajaxify(id, ajax_url){
console.log($('.chosen-search input').autocomplete);
$('div#' + id + '_chosen .chosen-search input').keyup(function(){
var keyword = $(this).val();
var keyword_pattern = new RegExp(keyword, 'gi');
$('div#' + id + '_chosen ul.chosen-results').empty();
$("#"+id).empty();
$.ajax({
url: ajax_url + keyword,
dataType: "json",
success: function(response){
// map, just as in functional programming :). Other way to say "foreach"
$.map(response, function(item){
$('#'+id).append('<option value="' + item.value + '">' + item.caption + '</option>');
});
$("#"+id).trigger("chosen:updated");
$('div#' + id + '_chosen').removeClass('chosen-container-single-nosearch');
$('div#' + id + '_chosen .chosen-search input').val(keyword);
$('div#' + id + '_chosen .chosen-search input').removeAttr('readonly');
$('div#' + id + '_chosen .chosen-search input').focus();
// put that underscores
$('div#' + id + '_chosen .active-result').each(function(){
var html = $(this).html();
$(this).html(html.replace(keyword_pattern, function(matched){
return '<em>' + matched + '</em>';
}));
});
}
});
});
}
Here is your HTML:
<select id="ajax_select"></select>
And here is your javasscript:
// This is also how you usually use chosen
$('#ajax_select').chosen({allow_single_deselect:true, width:"200px", search_contains: true});
// And this one is how you add AJAX capability
chosen_ajaxify('ajax_select', 'server.php?keyword=');
For more information, please refer to https://github.com/goFrendiAsgard/gofrendi.chosen.ajaxify#how-to-use
Another alternative is to use capturing sub-expressions with the regular expression functions regmatches
and regexec
.
# the original example
x <- 'hello stackoverflow'
# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', x))
This returns the entire string, the first character, and the "popped" result in a list of length 1.
myStrings
[[1]]
[1] "hello stackoverflow" "h" "ello stackoverflow"
which is equivalent to list(c(x, substr(x, 1, 1), substr(x, 2, nchar(x))))
. That is, it contains the super set of the desired elements as well as the full string.
Adding sapply
will allow this method to work for a character vector of length > 1.
# a slightly more interesting example
xx <- c('hello stackoverflow', 'right back', 'at yah')
# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', xx))
This returns a list with the matched full string as the first element and the matching subexpressions captured by ()
as the following elements. So in the regular expression '(^.)(.*)'
, (^.)
matches the first character and (.*)
matches the remaining characters.
myStrings
[[1]]
[1] "hello stackoverflow" "h" "ello stackoverflow"
[[2]]
[1] "right back" "r" "ight back"
[[3]]
[1] "at yah" "a" "t yah"
Now, we can use the trusty sapply
+ [
method to pull out the desired substrings.
myFirstStrings <- sapply(myStrings, "[", 2)
myFirstStrings
[1] "h" "r" "a"
mySecondStrings <- sapply(myStrings, "[", 3)
mySecondStrings
[1] "ello stackoverflow" "ight back" "t yah"
There are many ways to create and read properties
files:
.properties
extension however you can choose your own.java.util
package => Properties
, ListResourceBundle
, ResourceBundle
classes.Properties
or java.lang.System
class.ResourceBundle
class:
ResourceBundle rb = ResourceBundle.getBundle("prop"); // prop.properties
System.out.println(rb.getString("key"));
Properties
class:
Properties ps = new Properties();
ps.Load(new java.io.FileInputStream("my.properties"));
There is no language level support for this in MySQL. Here is a work-around involving MySQL information_schema meta-data in 5.0+, but it won't address your issue in 4.0.18.
drop procedure if exists schema_change;
delimiter ';;'
create procedure schema_change() begin
/* delete columns if they exist */
if exists (select * from information_schema.columns where table_schema = schema() and table_name = 'table1' and column_name = 'column1') then
alter table table1 drop column `column1`;
end if;
if exists (select * from information_schema.columns where table_schema = schema() and table_name = 'table1' and column_name = 'column2') then
alter table table1 drop column `column2`;
end if;
/* add columns */
alter table table1 add column `column1` varchar(255) NULL;
alter table table1 add column `column2` varchar(255) NULL;
end;;
delimiter ';'
call schema_change();
drop procedure if exists schema_change;
I wrote some more detailed information in a blog post.
In this particular case, an even simpler fix would be to just get rid of the "+" all together because AGE is a string literal and what comes before and after are also string literals. You could write line 3 as:
str += "Do you feel " AGE " years old?";
This is because most C/C++ compilers will concatenate string literals automatically. The above is equivalent to:
str += "Do you feel " "42" " years old?";
which the compiler will convert to:
str += "Do you feel 42 years old?";
The simplest way would be to convert your hexadecimal string to a byte array and use the File.WriteAllBytes
method.
Using the StringToByteArray()
method from this question, you'd do something like this:
string hexString = "0CFE9E69271557822FE715A8B3E564BE";
File.WriteAllBytes("output.dat", StringToByteArray(hexString));
The StringToByteArray
method is included below:
public static byte[] StringToByteArray(string hex) {
return Enumerable.Range(0, hex.Length)
.Where(x => x % 2 == 0)
.Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
.ToArray();
}
I wrote a tiny function for this purpose. Feel free to repurpose,
def is_json_key_present(json, key):
try:
buf = json[key]
except KeyError:
return False
return True
Execute this: npm install-test
Nothing helped me. Then I saw that the name of the project on the computer is different from the name on the git repository.
So I solved the problem.
Given int& arr[] = {a,b,c,8};
, what is sizeof(*arr)
?
Everywhere else, a reference is treated as being simply the thing itself, so sizeof(*arr)
should simply be sizeof(int)
. But this would make array pointer arithmetic on this array wrong (assuming that references are not the same widths is ints). To eliminate the ambiguity, it's forbidden.
If you need this and similar operations more often, it may be more convenient to find the right library instead of implementing it yourself.
Here are one-liners solving your question from Apache Commons Math using Precision, Colt using Functions, and Weka using Utils:
double value = 540.512 / 1978.8 * 100;
// Apache commons math
double rounded1 = Precision.round(value, 1);
double rounded2 = Precision.round(value, 1, BigDecimal.ROUND_HALF_UP);
// Colt
double rounded3 = Functions.round(0.1).apply(value)
// Weka
double rounded4 = Utils.roundDouble(value, 1)

TLDR:First determine where in the pipeline you're getting the error from (scroll looking for screenshots of something that resembles your error), make changes to get something new, repeat.
If you are seeing the file located here...
%SystemDrive%\inetpub\custerr\\500.htm
...which generally looks like this:
...then you know you are seeing the currently configured error page in **IIS ** and you do NOT need to change the ASP.net customErrors setting, asp error detail setting, or "show friendly http errors" browser setting.
You may want to look at the above referenced path instead of trusting my screenshot just in case somebody changed it.
In this case, you are seeing the setting of <httpErrors> or in IIS Manager it's Error Pages --> Edit Feature Settings. The default for this is errorMode=DetailedLocalOnly at the server node level (as opposed to the site level) which means that while you will see this configured error page while remote, you should be able to log on locally to the server and see the full error which should look something like this:
You should have everything that you need at that point to fix the current error.
That leaves a couple of possibilities.
Change your site's httpErrors to "Detailed" so you can see it remotely. But if it doesn't work your error might already be a config error, see #3 immediately above. So you might be stuck with #4 or #5 and you're going to need somebody from your server team.
...and you expect to see something like this...
...then you need to change "Send errors to browser" to true in IIS Manager, under Site --> IIS --> ASP --> Debugging Properties
or this...
...you need to disable friendly errors in your browser or use fiddler's webview to look at the actual response vs what your browser chooses to show you.
If you see this...
...then custom errors is working but you don't have a custom error page (of course at this point were talking about .net and not classic asp). You need to change your customErrors tag in your web.config to RemoteOnly to view on the server, or Off to view remotely.
If you see something that is styled like your site, then custom errors is likely On or RemoteOnly and it's displaying the custom page (Views->Shared->Error.cshtml in MVC for example). That said, it is unlikely but possible that somebody changed the pages in IIS for httpErrors so see the first section on that.
Just create a data.frame
with 0 length variables
eg
nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)
## 'data.frame': 0 obs. of 3 variables:
## $ x: num
## $ y: int
## $ z: Factor w/ 0 levels:
or to create a data.frame with 5 columns named a,b,c,d,e
nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))
You can limit in following way. First is starting index and second is number of characters.
**{{ results['text'][4:2] }}**

I finally figured it out doing this:
var $your-original-element = $('.your-original-element');
var data = $your-original-element.select2('data')[0]['text'];
alert(data);
if you also want the value:
var value = $your-original-element.select2('data')[0]['id'];
alert(value);

After a lot of time spending, I decided to use an external library named email-validator
, install it easily by npm for example and import/require it in your own project:
https://www.npmjs.com/package/email-validator
//NodeJs
const validator = require("email-validator");
validator.validate("[email protected]"); // true
//TypeScript/JavaScript
import * as EmailValidator from 'email-validator';
EmailValidator.validate("[email protected]"); // true
As it's an issue we face more than often, below are the steps to resolve it.
Open the Git perspective. In the Git Repository view, go to on Branches ? Local ? master and right click ? Merge...
It should auto select Remote Tracking ? *origin/master. Press Merge.
Launch stage view in Eclipse.
Double click the files which initially showed conflict
In the conflict merge view, by selecting the left arrow for all the non-conflict + conflict changes from left to right, you can resolve all the conflicts.
Save the merged file.
Do a Team ? pull from Eclipse again.
You are all set :)
If you have a text box to type the file path, just use sendkeys to input the file path and click on submit button. If there is no text box to type the file path and only able to click on browse button and to select the file from windows popup, you can use AutoIt tool, see the step below to use AutoIt for the same,
Download and Install Autoit tool from http://www.autoitscript.com/site/autoit/
Open Programs -> Autoit tool -> SciTE Script Editor.
Paste the following code in Autoit editor and save it as “filename.exe “(eg: new.exe)
Then compile and build the file to make it exe. (Tools ? Compile)
Autoit Code:
WinWaitActive("File Upload"); Name of the file upload window (Windows Popup Name: File Upload)
Send("logo.jpg"); File name
Send("{ENTER}")
Then Compile and Build from Tools menu of the Autoit tool -> SciTE Script Editor.
Paste the below Java code in Eclipse editor and save
Java Code:
driver.findElement(By.id("uploadbutton")).click; // open the Upload window using selenium
Thread.sleep("20000"); // wait for page load
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "C:\\Documents and Settings\\new.exe"); // Give path where the exe is saved.
var string = 'a,b,c,d',
strx = string.split(',');
array = [];
array = array.concat(strx);
// ["a","b","c","d"]
You could also use:
request.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
If you have control over the entity that's returning true
/false
, one option is to have it return 1
/0
instead of true
/false
, then:
boolean_response = bool(int(response))
The extra cast to int
handles responses from a network, which are always string.
Update 2021: "which are always string" -- this is a naive observation. It depends on the serialization protocol used by the library. Default serialization of high-level libraries (the ones used by most web devs) is typically to convert to string before being serialized to bytes. And then on the other side, it's deserialized from bytes to string, so you've lost any type information.
You will find Python's string literal documentation here:
http://docs.python.org/tutorial/introduction.html#strings
and here:
http://docs.python.org/reference/lexical_analysis.html#literals
The simplest example would be using the 'r' prefix:
ss = r'Hello\nWorld'
print(ss)
Hello\nWorld
new XElement("Foo",
from s in nameValuePairList
select
new XElement("Bar",
new XAttribute("SomeAttr", "SomeAttrValue"),
new XElement("Name", s.Name),
new XElement("Value", s.Value)
)
);
Check: key = undef !!!
You got also the warn message:
Each child in a list should have a unique "key" prop.
if your code is complete right, but if on
<MyComponent key={someValue} />
someValue is undefined!!! Please check this first. You can save hours.
PPI and DPI make absolutely no difference to how a document will print off a browser. the printer takes no information on screen dot pitch or the DPI of the images etc. if you are printing images they would print at a size similar in proportion to how they are displayed on screen. the print processor of the browser would increase the DPI of the images from something rather low like 72dpi to whatever DPI the rest of the document is. say the image displays as half a page wide, then its about 4" wide physically. the pixel width of the image would be approx 300px to display correctly in the browser. by the time it prints at a nominal 300DPI, the processor has added pixels and the image will grow to around 1200px which at 300 DPI is 4".
when it comes to vector or non pixel based elements like text, the printer chooses its own DPI from the driver which doesnt relate to screen dot pitch or browser width etc. if the browser is 3000px wide, the print processor will wrap text as appropriate.
heres what makes it hard about creating print displays: each browser and printer will interpret text sizes (pt, em, px) and spacing in its own way. depending on what printer, browser and maybe even OS you use, you will get a different amount of lines and characters per page. so even if you test on your computer using your browser and printer and figure out that you can display the text in a box at 640x900px and its perfect on print, the next guy who tries to print will possibly get it printing differently. there really is no way to force each printer and browser to get it identical each time.
forget pixels and moreso forget DPI, the only thing you could use pixels for is setting a table width that simulates the width of a printable area on your printer. in that case i found that 640px wide is close.
If you are familiar with RxJava, you can use Observable.interval(), which is pretty neat.
Observable.interval(60, TimeUnits.SECONDS)
.flatMap(new Function<Long, ObservableSource<String>>() {
@Override
public ObservableSource<String> apply(@NonNull Long aLong) throws Exception {
return getDataObservable(); //Where you pull your data
}
});
The downside of this is that you have to architect polling your data in a different way. However, there are a lot of benefits to the Reactive Programming way:
With RxAndroid, you can handle threads in just 2 lines of code.
Observable.interval(60, TimeUnits.SECONDS)
.flatMap(...) // polling data code
.subscribeOn(Schedulers.newThread()) // poll data on a background thread
.observeOn(AndroidSchedulers.mainThread()) // populate UI on main thread
.subscribe(...); // your UI code
Please check out RxJava. It has a high learning curve but it will make handling asynchronous calls in Android so much easier and cleaner.
The following command will create a copy in a new window. So you can continue see both original file and the new file.

We are using akka with its camel plugin to distribute our analysis and trending processing for twimpact.com. We have to process between 50 and 1000 messages per second. In addition to multi-node processing with camel it is also used to distribute work on a single processor to multiple workers for maximum performance. Works quite well, but requires some understanding of how to handle congestions.
Here is the full description to create the first program using the express generator,
Ubuntu's package manager
To install Node.js and npm via apt-get, run these commands:
sudo apt-get update
sudo apt-get install nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node
sudo apt-get install npm
Express application generator:
$ npm install express-generator -g
Display the command options with the -h
option:
$ express -h
Usage: express [options] [dir]
Options:
-h, --help output usage information
-V, --version output the version number
-e, --ejs add ejs engine support (defaults to jade)
--hbs add handlebars engine support
-H, --hogan add hogan.js engine support
-c, --css <engine> add stylesheet <engine> support (less|stylus|compass|sass) (defaults to plain css)
--git add .gitignore
-f, --force force on non-empty directory
For example, the following creates an Express application named myapp in the current working directory:
$ express myapp
create : myapp
create : myapp/package.json
create : myapp/app.js
create : myapp/public
create : myapp/public/javascripts
create : myapp/public/images
create : myapp/routes
create : myapp/routes/index.js
create : myapp/routes/users.js
create : myapp/public/stylesheets
create : myapp/public/stylesheets/style.css
create : myapp/views
create : myapp/views/index.jade
create : myapp/views/layout.jade
create : myapp/views/error.jade
create : myapp/bin
create : myapp/bin/www
Then install dependencies:
$ cd myapp
$ npm install
Run the app with this command:
$ DEBUG=myapp:* npm start
Then load http://localhost:3000/ in your browser to access the application.
The generated application has the following directory structure:
+-- app.js
+-- bin
¦ +-- www
+-- package.json
+-- public
¦ +-- images
¦ +-- javascripts
¦ +-- stylesheets
¦ +-- style.css
+-- routes
¦ +-- index.js
¦ +-- users.js
+-- views
+-- error.jade
+-- index.jade
+-- layout.jade

For proxy_upstream
timeout, I tried the above setting but these didn't work.

Your app is attempting to parse the undefined JSON web token. Such malfunction may occur due to the wrong usage of the local storage. Try to clear your local storage.
Example for Google Chrome:
This is not exactly the OP's scenario but an answer to those of some of the commenters. It is a solution based on Cordova and Angular 1, which should be adaptable to other frameworks like jQuery. It gives you a Blob from Base64 data which you can store somewhere and reference it from client side javascript / html.
It also answers the original question on how to get an image (file) from the Base 64 data:
The important part is the Base 64 - Binary conversion:
function base64toBlob(base64Data, contentType) {
contentType = contentType || '';
var sliceSize = 1024;
var byteCharacters = atob(base64Data);
var bytesLength = byteCharacters.length;
var slicesCount = Math.ceil(bytesLength / sliceSize);
var byteArrays = new Array(slicesCount);
for (var sliceIndex = 0; sliceIndex < slicesCount; ++sliceIndex) {
var begin = sliceIndex * sliceSize;
var end = Math.min(begin + sliceSize, bytesLength);
var bytes = new Array(end - begin);
for (var offset = begin, i = 0; offset < end; ++i, ++offset) {
bytes[i] = byteCharacters[offset].charCodeAt(0);
}
byteArrays[sliceIndex] = new Uint8Array(bytes);
}
return new Blob(byteArrays, { type: contentType });
}
Slicing is required to avoid out of memory errors.
Works with jpg and pdf files (at least that's what I tested). Should work with other mimetypes/contenttypes too. Check the browsers and their versions you aim for, they need to support Uint8Array, Blob and atob.
Here's the code to write the file to the device's local storage with Cordova / Android:
...
window.resolveLocalFileSystemURL(cordova.file.externalDataDirectory, function(dirEntry) {
// Setup filename and assume a jpg file
var filename = attachment.id + "-" + (attachment.fileName ? attachment.fileName : 'image') + "." + (attachment.fileType ? attachment.fileType : "jpg");
dirEntry.getFile(filename, { create: true, exclusive: false }, function(fileEntry) {
// attachment.document holds the base 64 data at this moment
var binary = base64toBlob(attachment.document, attachment.mimetype);
writeFile(fileEntry, binary).then(function() {
// Store file url for later reference, base 64 data is no longer required
attachment.document = fileEntry.nativeURL;
}, function(error) {
WL.Logger.error("Error writing local file: " + error);
reject(error.code);
});
}, function(errorCreateFile) {
WL.Logger.error("Error creating local file: " + JSON.stringify(errorCreateFile));
reject(errorCreateFile.code);
});
}, function(errorCreateFS) {
WL.Logger.error("Error getting filesystem: " + errorCreateFS);
reject(errorCreateFS.code);
});
...
Writing the file itself:
function writeFile(fileEntry, dataObj) {
return $q(function(resolve, reject) {
// Create a FileWriter object for our FileEntry (log.txt).
fileEntry.createWriter(function(fileWriter) {
fileWriter.onwriteend = function() {
WL.Logger.debug(LOG_PREFIX + "Successful file write...");
resolve();
};
fileWriter.onerror = function(e) {
WL.Logger.error(LOG_PREFIX + "Failed file write: " + e.toString());
reject(e);
};
// If data object is not passed in,
// create a new Blob instead.
if (!dataObj) {
dataObj = new Blob(['missing data'], { type: 'text/plain' });
}
fileWriter.write(dataObj);
});
})
}
I am using the latest Cordova (6.5.0) and Plugins versions:
I hope this sets everyone here in the right direction.
The right way is using insertAdjacentHTML
. In Firefox earlier than 8, you can fall back to using Range.createContextualFragment
if your str
contains no script
tags.
If your str
contains script
tags, you need to remove script
elements from the fragment returned by createContextualFragment
before inserting the fragment. Otherwise, the scripts will run. (insertAdjacentHTML
marks scripts unexecutable.)
You can turn off caching with Firefox's web developer toolbar.
The best way to do that programmatically is using the next method:
public static DigitsKeyListener getInstance (boolean sign, boolean decimal)
Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.
This solve the problem about the many '.' in EditText
editText.setKeyListener(DigitsKeyListener.getInstance(true,true)); // decimals and positive/negative numbers.
editText.setKeyListener(DigitsKeyListener.getInstance(false,true)); // positive decimals numbers.
editText.setKeyListener(DigitsKeyListener.getInstance(false,false)); // positive integer numbers.
editText.setKeyListener(DigitsKeyListener.getInstance(true,false)); // positive/negative integer numbers.
The .before
argument in dplyr::add_row
can be used to specify the row.
dplyr::add_row(
cars,
speed = 0,
dist = 0,
.before = 3
)
#> speed dist
#> 1 4 2
#> 2 4 10
#> 3 0 0
#> 4 7 4
#> 5 7 22
#> 6 8 16
#> ...
From my experience, there is at least one clear advantage when using event.preventDefault() over using return false. Suppose you are capturing the click event on an anchor tag, otherwise which it would be a big problem if the user were to be navigated away from the current page. If your click handler uses return false to prevent browser navigation, it opens the possibility that the interpreter will not reach the return statement and the browser will proceed to execute the anchor tag's default behavior.
$('a').click(function (e) {
// custom handling here
// oops...runtime error...where oh where will the href take me?
return false;
});
The benefit to using event.preventDefault() is that you can add this as the first line in the handler, thereby guaranteeing that the anchor's default behavior will not fire, regardless if the last line of the function is not reached (eg. runtime error).
$('a').click(function (e) {
e.preventDefault();
// custom handling here
// oops...runtime error, but at least the user isn't navigated away.
});
There's two ways to say "don't match": character ranges, and zero-width negative lookahead/lookbehind.
The former: don't match a
, b
, c
or 0
: [^a-c0]
The latter: match any three-letter string except foo
and bar
:
(?!foo|bar).{3}
or
.{3}(?<!foo|bar)
Also, a correction for you: *
, ?
and +
do not actually match anything. They are repetition operators, and always follow a matching operator. Thus, a+
means match one or more of a
, [a-c0]+
means match one or more of a
, b
, c
or 0
, while [^a-c0]+
would match one or more of anything that wasn't a
, b
, c
or 0
.
On the above example I kept losing the values, I think that delaying the Validation will allow the new data types to be saved as part of the meta data.
On the connection Manager for 'Excel Connection Manager' set the Delay Validation to False from the Properties.
Then on the data flow Destination task for Excel set the ValidationExternalMetaData to False, again from the properties.
This will now allow you to right click on the Excel Destination Task and go to Advanced Editor for Excel Destination --> far right tab - Input and Output Properties. In the External Columns folder section you will be able to now change the Data Types and Length values of the problematic columns and this can now be saved.
Good Luck!

You can send email without Outlook in VBScript using the CDO.Message object. You will need to know the address of your SMTP server to use this:
Set MyEmail=CreateObject("CDO.Message")
MyEmail.Subject="Subject"
MyEmail.From="[email protected]"
MyEmail.To="[email protected]"
MyEmail.TextBody="Testing one two three."
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing")=2
'SMTP Server
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver")="smtp.server.com"
'SMTP Port
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25
MyEmail.Configuration.Fields.Update
MyEmail.Send
set MyEmail=nothing
If your SMTP server requires a username and password then paste these lines in above the MyEmail.Configuration.Fields.Update
line:
'SMTP Auth (For Windows Auth set this to 2)
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate")=1
'Username
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusername")="username"
'Password
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendpassword")="password"
More information on using CDO to send email with VBScript can be found on the link below: http://www.paulsadowski.com/wsh/cdo.htm
With this you can remove the column
and store variable
into another variable
.
df = subset(data, select = -c(genome) )
There is a better solution to this answer that is more Angular based.
Save your string in a variable in the .ts file
MyStrings = ["one","two","three"]
In the html file use *ngFor.
<div class="one" *ngFor="let string of MyStrings; let i = index">
<div class="two">{{string}}</div>
</div>
if you want to dynamically insert the div element, just push more strings into the MyStrings array
myFunction(nextString){
this.MyString.push(nextString)
}
this way every time you click the button containing the myFunction(nextString) you effectively add another class="two" div which acts the same way as inserting it into the DOM with pure javascript.
To specify versions, or commits:
go get -u [email protected]
go get -u otherpackage@git-sha

This can be done for free using GIMP.
It uses the ability of GIMP to have each layer a different size.
I created the following layers sized correctly.
Notes
function yourfunctionName() {
var yourFileName = $("#yourinputfieldis").val();
var yourFileExtension = yourFileName .replace(/^.*\./, '');
switch (yourFileExtension ) {
case 'pdf':
case 'jpg':
case 'doc':
$("#formId").submit();// your condition what you want to do
break;
default:
alert('your File extension is wrong.');
this.value = '';
}
}
AFAIK there is no possibility beside from using keys or expect if you are using the command line version ssh
. But there are library bindings for the most programming languages like C, python, php, ... . You could write a program in such a language. This way it would be possible to pass the password automatically. But note this is of course a security problem as the password will be stored in plain text in that program
If you use Kotlin language you just add this code:
Create global variables of GoogleMap
and Marker
types.
I use variable marker to make variable marker value can change directly
private lateinit var map: GoogleMap
private lateinit var marker: Marker
And I use this function/method to add the marker on my map:
private fun placeMarkerOnMap(location: LatLng) {
val markerOptions = MarkerOptions().position(location)
val titleStr = getAddress(location)
markerOptions.title(titleStr)
marker = map.addMarker(markerOptions)
}
After I create the function I place this code on the onMapReady()
to remove the marker and create a new one:
map.setOnMapClickListener { location ->
map.clear()
marker.remove()
placeMarkerOnMap(location)
}
It's bonus if you want to display the address location when you click the marker add this code to hide and show the marker address but you need a method to get the address location. I got the code from this post: How to get complete address from latitude and longitude?
map.setOnMarkerClickListener {marker ->
if (marker.isInfoWindowShown){
marker.hideInfoWindow()
}else{
marker.showInfoWindow()
}
true
}

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)
mp <- within(mp,
{
wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
wow <- rnorm(N)*wav+rnorm(N)*wav^3
})
m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))
Get fitted values (the same as m01$fitted
)
fit <- predict(m01)
Normally we could use something like predict(...,se.fit=TRUE)
to get the confidence intervals on the prediction, but gls
doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :
V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))
Put together a "prediction frame":
predframe <- with(mp,data.frame(year,wav,
wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))
Now plot with geom_ribbon
(p1 <- ggplot(mp, aes(year, wow))+
geom_point()+
geom_line(data=predframe)+
geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))
It's easier to see that we got the right answer if we plot against wav
rather than year
:
(p2 <- ggplot(mp, aes(wav, wow))+

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly()
fits -- see ?makepredictcall

I am using Linux raspi 4.19.118+ #1311 via ssh Powershell on Win 10 Pro 1909 with German keyboard. nano shortcut Goto Line with "Crtl + Shift + -" was not working Solution: Step 1 - Do Current Position with "Crtl + C" Step 2 - Goto Line with "Crtl + Shift + -" IS working!
I dont know what effects it. But now its working without step 1!
In EntityFrameworkCore:
Update-Database 20161012160749_AddedOrderToCourse
where 20161012160749_AddedOrderToCourse
is a name of migration you want to rollback to.
The current way to do this is by using the "Add Service Reference" command. If you specify "TestUploaderWebService
" as the service reference name, that will generate the type TestUploaderWebService.Service1
. That class will have a method named GetFileListOnWebServer
, which will return an array of strings (you can change that to be a list of strings if you like). You would use it like this:
string[] files = null;
TestUploaderWebService.Service1 proxy = null;
bool success = false;
try
{
proxy = new TestUploaderWebService.Service1();
files = proxy.GetFileListOnWebServer();
proxy.Close();
success = true;
}
finally
{
if (!success)
{
proxy.Abort();
}
}
P.S. Tell your instructor to look at "Microsoft: ASMX Web Services are a “Legacy Technology”", and ask why he's teaching out of date technology.
You can use it without casting such as:
select sum(`stuff`) as mySum from test;
Or cast it to decimal:
select sum(cast(`stuff` as decimal(4,2))) as mySum from test;
EDIT
For SQL Server, you can use:
select sum(cast(stuff as decimal(5,2))) as mySum from test;
Just go to res>values>strings.xml. One line says Somethig-your name
<string name="app_name">Somethig-your name</string>
Just replace your original name to
<string name="app_name">Your Name</string>
I tried this with Visual Studio 2013 Express, using a pointer instead of an index, which sped up the process a bit. I suspect this is because the addressing is offset + register, instead of offset + register + (register<<3). C++ code.
uint64_t* bfrend = buffer+(size/8);
uint64_t* bfrptr;
// ...
{
startP = chrono::system_clock::now();
count = 0;
for (unsigned k = 0; k < 10000; k++){
// Tight unrolled loop with uint64_t
for (bfrptr = buffer; bfrptr < bfrend;){
count += __popcnt64(*bfrptr++);
count += __popcnt64(*bfrptr++);
count += __popcnt64(*bfrptr++);
count += __popcnt64(*bfrptr++);
}
}
endP = chrono::system_clock::now();
duration = chrono::duration_cast<std::chrono::nanoseconds>(endP-startP).count();
cout << "uint64_t\t" << count << '\t' << (duration/1.0E9) << " sec \t"
<< (10000.0*size)/(duration) << " GB/s" << endl;
}
assembly code: r10 = bfrptr, r15 = bfrend, rsi = count, rdi = buffer, r13 = k :

Depending on where the InputStream is coming from, you might not be able to reset it. You can check if mark()
and reset()
are supported using markSupported()
.
If it is, you can call reset()
on the InputStream to return to the beginning. If not, you need to read the InputStream from the source again.
before_filter/before_action: means anything to be executed before any action executes.
Both are same. they are just alias for each other as their behavior is same.
Found a solution to this. Just ISNULL
the CASE
statement:
ISNULL(CASE x WHEN x THEN x ELSE x END, '') AS 'BLAH'
In IB, set number of lines to 0 (allows unlimited lines)
When typing within the text field using IB, use "alt-return" to insert a return and go to the next line (or you can copy in text already separated out by lines).
You can use filter_var
filter_var(
$yourInteger,
FILTER_VALIDATE_INT,
array(
'options' => array(
'min_range' => $min,
'max_range' => $max
)
)
);
This will also allow you to specify whether you want to allow octal and hex notation of integers. Note that the function is type-safe. 5.5
is not an integer but a float and will not validate.
Detailed tutorial about filtering data with PHP:
One trick is to create an interface that extends a generic base interface...
public interface LoadFutures extends Map<UUID, Future<LoadResult>> {}
Then you can check it with instanceof before the cast...
Object obj = context.getAttribute(FUTURES);
if (!(obj instanceof LoadFutures)) {
String format = "Servlet context attribute \"%s\" is not of type "
+ "LoadFutures. Its type is %s.";
String msg = String.format(format, FUTURES, obj.getClass());
throw new RuntimeException(msg);
}
return (LoadFutures) obj;
if you don't want to use json.parse(json.stringify(object)) you could create recursively key-value copies:
function copy(item){
let result = null;
if(!item) return result;
if(Array.isArray(item)){
result = [];
item.forEach(element=>{
result.push(copy(element));
});
}
else if(item instanceof Object && !(item instanceof Function)){
result = {};
for(let key in item){
if(key){
result[key] = copy(item[key]);
}
}
}
return result || item;
}
But the best way is to create a class that can return a clone of it self
class MyClass{
data = null;
constructor(values){ this.data = values }
toString(){ console.log("MyClass: "+this.data.toString(;) }
remove(id){ this.data = data.filter(d=>d.id!==id) }
clone(){ return new MyClass(this.data) }
}
Inspired by @Terre Porter's answer, I think this one is very simple to implement (using jQuery)
var $options = jQuery("#my-dropdownlist-id > option");
// or jQuery("#my-dropdownlist-id").find("option")
$options.sort(function(a, b) {
return a.text == b.text ? 0 : a.text < b.text ? -1 : 1
})
But, for Alpha/Numeric dropdown lists :
Inspired by : https://stackoverflow.com/a/4340339/1598891
var $options = jQuery(dropDownList).find("option");
var reAlpha = /[^a-zA-Z]/g;
var reNumeric = /[^0-9]/g;
$options.sort(function AlphaNumericSort($a,$b) {
var a = $a.text;
var b = $b.text;
var aAlpha = a.replace(reAlpha, "");
var bAlpha = b.replace(reAlpha, "");
if(aAlpha === bAlpha) {
var aNumeric = parseInt(a.replace(reNumeric, ""), 10);
var bNumeric = parseInt(b.replace(reNumeric, ""), 10);
return aNumeric === bNumeric ? 0 : aNumeric > bNumeric ? 1 : -1;
} else {
return aAlpha > bAlpha ? 1 : -1;
}
})
Hope it will help
This was pretty well answered over here: How to make a YouTube embedded video a full page width one?
If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)
<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>
of the video it should play on load. Here's a demo over at jsfiddle.
You are going to have to truncate the values yourself as strings before you put them into that column.
Otherwise, if you want more decimal places, you will need to change your declaration of the decimal column.
string.join
connects elements inside list of strings, not ints.
Use this generator expression instead :
values = ','.join(str(v) for v in value_list)
You can use Manifold's @JailBreak for direct, type-safe Java reflection:
@JailBreak Foo foo = new Foo();
foo.stuffIWant = "123;
public class Foo {
private String stuffIWant;
}
@JailBreak
unlocks the foo
local variable in the compiler for direct access to all the members in Foo
's hierarchy.
Similarly you can use the jailbreak() extension method for one-off use:
foo.jailbreak().stuffIWant = "123";
Through the jailbreak()
method you can access any member in Foo
's hierarchy.
In both cases the compiler resolves the field access for you type-safely, as if a public field, while Manifold generates efficient reflection code for you under the hood.
