select DocumentFormat.OpenXml under references , view it's properties, and set the Copy Local option to True so that it copies it to the output folder. That worked for me.
I just knocked up a quick procedure to do this. It only works for a single row, so I create a temporary view that just selects the row I want, and then replace the pg_temp.temp_view with the actual table that I want to insert into.
CREATE OR REPLACE FUNCTION dv_util.gen_insert_statement(IN p_schema text, IN p_table text)
RETURNS text AS
$BODY$
DECLARE
selquery text;
valquery text;
selvalue text;
colvalue text;
colrec record;
BEGIN
selquery := 'INSERT INTO ' || quote_ident(p_schema) || '.' || quote_ident(p_table);
selquery := selquery || '(';
valquery := ' VALUES (';
FOR colrec IN SELECT table_schema, table_name, column_name, data_type
FROM information_schema.columns
WHERE table_name = p_table and table_schema = p_schema
ORDER BY ordinal_position
LOOP
selquery := selquery || quote_ident(colrec.column_name) || ',';
selvalue :=
'SELECT CASE WHEN ' || quote_ident(colrec.column_name) || ' IS NULL' ||
' THEN ''NULL''' ||
' ELSE '''' || quote_literal('|| quote_ident(colrec.column_name) || ')::text || ''''' ||
' END' ||
' FROM '||quote_ident(p_schema)||'.'||quote_ident(p_table);
EXECUTE selvalue INTO colvalue;
valquery := valquery || colvalue || ',';
END LOOP;
-- Replace the last , with a )
selquery := substring(selquery,1,length(selquery)-1) || ')';
valquery := substring(valquery,1,length(valquery)-1) || ')';
selquery := selquery || valquery;
RETURN selquery;
END
$BODY$
LANGUAGE plpgsql VOLATILE;
Invoked thus:
SELECT distinct dv_util.gen_insert_statement('pg_temp_' || sess_id::text,'my_data')
from pg_stat_activity
where procpid = pg_backend_pid()
I haven't tested this against injection attacks, please let me know if the quote_literal call isn't sufficient for that.
Also it only works for columns that can be simply cast to ::text and back again.
Also this is for Greenplum but I can't think of a reason why it wouldn't work on Postgres, CMIIW.

This question has been addressed, in a slightly different form, at length, here:
But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:
Matasano's article on this is famous, but the lessons contained therein are pretty important:
To summarize:
<script>
function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
And to add a corollary of my own:
This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!
First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.
This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.
The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.
This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!
The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.
Is Digest authentication possible with jQuery?
A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.
Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.
http://tools.ietf.org/html/rfc5849
Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?
JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.
The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.
This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.
The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.
To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.
It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX
". Many of these policies are pretty good ideas.
However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/
The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.
tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.
The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?
Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.
It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.
Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:
Aside from that, though, it's no different from Token Auth, really.
This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.
OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."
The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."
Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.
There are two ways that OAuth 2.0 can help you:
But when it comes down to it, you're just... using tokens.
So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"
And the answer is: do whatever makes you happy.
The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.
The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.
Use __name__
attribute:
# foo.py
def bar():
print(f"my name is {bar.__name__}")
You can easily access function's name from within the function using __name__
attribute.
>>> def bar():
... print(f"my name is {bar.__name__}")
...
>>> bar()
my name is bar
I've come across this question myself several times, looking for the ways to do it. Correct answer is contained in the Python's documentation (see Callable types section).
Every function has a __name__
parameter that returns its name and even __qualname__
parameter that returns its full name, including which class it belongs to (see Qualified name).
You can use .loc
to select the specific columns with all rows and then pull that. An example is below:
pandas.merge(dataframe1, dataframe2.iloc[:, [0:5]], how='left', on='key')
In this example, you are merging dataframe1 and dataframe2. You have chosen to do an outer left join on 'key'. However, for dataframe2 you have specified .iloc
which allows you to specific the rows and columns you want in a numerical format. Using :
, your selecting all rows, but [0:5]
selects the first 5 columns. You could use .loc
to specify by name, but if your dealing with long column names, then .iloc
may be better.
You could ignore SIGINTs after shutdown starts by calling signal.signal(signal.SIGINT, signal.SIG_IGN)
before you start your cleanup code.
The Chosen plugin does not automatically update its list of options when the OPTION elements in the DOM change. You have to send it an event to trigger the update:
Pre Chosen 1.0:
$('.chzn-select').trigger("liszt:updated");
Chosen 1.0
$('.chosen-select').trigger("chosen:updated");
If you are dynamically managing the OPTION elements, then you'll have to do this whenever the OPTIONs change. The way you do this will vary - in AngularJS, try something like this:
$scope.$watch(
function() {
return element.find('option').map(function() { return this.value }).get().join();
},
function() {
element.trigger('liszt:updated');
}
}
Try using setAttribute
instead:
document.getElementById('img')
.setAttribute(
'src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='
);
Real answer: (And make sure you remove the line-breaks in the base64.)

Use Element#outerHTML:
var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));
console.log(el.outerHTML);
It can also be used to write DOM elements. From Mozilla's documentation:
The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. It can be set to replace the element with nodes parsed from the given string.
https://developer.mozilla.org/en-US/docs/Web/API/Element/outerHTML
In short: I don't think you can, but there seems to be a workaround:.
If you take a look into the Android Resource here:
http://developer.android.com/guide/topics/resources/string-resource.html
You see than under the array section (string array, at least), the "RESOURCE REFERENCE" (as you get from an XML) does not specify a way to address the individual items. You can even try in your XML to use "@array/yourarrayhere". I know that in design time you will get the first item. But that is of no practical use if you want to use, let's say... the second, of course.
HOWEVER, there is a trick you can do. See here:
Referencing an XML string in an XML Array (Android)
You can "cheat" (not really) the array definition by addressing independent strings INSIDE the definition of the array. For example, in your strings.xml:
<string name="earth">Earth</string>
<string name="moon">Moon</string>
<string-array name="system">
<item>@string/earth</item>
<item>@string/moon</item>
</string-array>
By using this, you can use "@string/earth" and "@string/moon" normally in your "android:text" and "android:title" XML fields, and yet you won't lose the ability to use the array definition for whatever purposes you intended in the first place.
Seems to work here on my Eclipse. Why don't you try and tell us if it works? :-)
In Java 8 we can solve it as:
String str = "xyz";
str.chars().forEachOrdered(i -> System.out.print((char)i));
The method chars() returns an IntStream
as mentioned in doc:
Returns a stream of int zero-extending the char values from this sequence. Any char which maps to a surrogate code point is passed through uninterpreted. If the sequence is mutated while the stream is being read, the result is undefined.
forEachOrdered
and not forEach
?The behaviour of forEach
is explicitly nondeterministic where as the forEachOrdered
performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach
does not guarantee that the order would be kept. Also check this question for more.
We could also use codePoints()
to print, see this answer for more details.

max
is built in function which takes first argument an iterable
(like list or tuple)
keyword argument key
has it's default value None
but it accept function to evaluate, consider it as wrapper which evaluates iterable based on function
Consider this example dictionary:
d = {'aim':99, 'aid': 45, 'axe': 59, 'big': 9, 'short': 995, 'sin':12, 'sword':1, 'friend':1000, 'artwork':23}
Ex:
>>> max(d.keys())
'sword'
As you can see if you only pass the iterable without kwarg(a function to key
) it is returning maximum value of key(alphabetically)
Ex. Instead of finding max value of key alphabetically you might need to find max key by length of key:
>>>max(d.keys(), key=lambda x: len(x))
'artwork'
in this example lambda function is returning length of key which will be iterated hence while evaluating values instead of considering alphabetically it will keep track of max length of key and returns key which has max length
Ex.
>>> max(d.keys(), key=lambda x: d[x])
'friend'
in this example lambda function is returning value of corresponding dictionary key which has maximum value
The standard MIME type for ZIP files is application/zip
. The types for the files inside the ZIP does not matter for the MIME type.
As always, it ultimately depends on your server setup.

Step 1: setAdapter to your listview.
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, GENRES));
Step 2: set choice mode for listview .The second line of below code represents which checkbox should be checked.
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setItemChecked(2, true);
listView.setOnItemClickListener(this);
private static String[] GENRES = new String[] {
"Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama",
"Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller"
};
Step 3: Checked views are returned in SparseBooleanArray, so you might use the below code to get key or values.The below sample are simply displayed selected names in a single String.
@Override
public void onItemClick(AdapterView<?> adapter, View arg1, int arg2, long arg3)
{
SparseBooleanArray sp=getListView().getCheckedItemPositions();
String str="";
for(int i=0;i<sp.size();i++)
{
str+=GENRES[sp.keyAt(i)]+",";
}
Toast.makeText(this, ""+str, Toast.LENGTH_SHORT).show();
}

If you want to monitor the execution of task, you could spin 1 or 2 threads (maybe more depending on the load) and use them to take tasks from an ExecutionCompletionService wrapper.
Be careful where you set WORKDIR
because it can affect the continuous integration flow. For example, setting it to /home/circleci/project
will cause error something like .ssh
or whatever is the remote circleci is doing at setup time.
This is very simple.Such as:
["1", "2", "3", "4"].map(i=>Number(i))
you can run the demo.
let result = ["1", "2", "3", "4"].map(i=>Number(i));
console.log(result);

This would work very well -- You can use HTML5 to allow only image files to be uploaded. This is the code for uploader.htm --
<html>
<head>
<script>
function validateForm(){
var image = document.getElementById("image").value;
var name = document.getElementById("name").value;
if (image =='')
{
return false;
}
if(name =='')
{
return false;
}
else
{
return true;
}
return false;
}
</script>
</head>

<input type="file" accept="image/*" name="image" id="image" />
<input type="submit" value='Save' onclick="return validateForm()"/>

list($w, $h) = getimagesize($saveto);
$max = 100;
$tw = $w;
$th = $h;
if ($w > $h && $max < $w)

Other answers already cover how to filter by an address, but if you would like to exclude an address use

i used jQuery's event delegation /bubbling... that worked for me. See below:
$(document).on('click', '#btnSubmit', function () {
alert('hi loo');
})
very good info too: https://learn.jquery.com/events/event-delegation/
There is another way. If you're passing an object by reference, that object's properties will appear in the function's local scope. I know this works for Safari (haven't checked other browsers) and I don't know if this feature has a name, but the below example illustrates its use.
Although in practice I don't think that this offers any functional value beyond the technique you're already using, it's a little cleaner semantically. And it still requires passing a object reference or an object literal.
function sum({ a:a, b:b}) {
console.log(a+'+'+b);
if(a==undefined) a=0;
if(b==undefined) b=0;
return (a+b);
}
// will work (returns 9 and 3 respectively)
console.log(sum({a:4,b:5}));
console.log(sum({a:3}));
// will not work (returns 0)
console.log(sum(4,5));
console.log(sum(4));
Now there is the pandas_profiling
package, which is a more complete alternative to df.describe()
.
If your pandas dataframe is df
, the below will return a complete analysis including some warnings about missing values, skewness, etc. It presents histograms and correlation plots as well.
import pandas_profiling
pandas_profiling.ProfileReport(df)
See the example notebook detailing the usage.
A good example could be next: for instance you have a set of Loggers and you allows user to specify type to be used in runtime via configuration file.
Then:
string rawLoggerType = configurationService.GetLoggerType();
Type loggerType = Type.GetType(rawLoggerType);
ILogger logger = Activator.CreateInstance(loggerType.GetType()) as ILogger;
OR another case is when you have a common entities factory, which creates entity, and is also responsible on initialization of an entity by data received from DB:
(pseudocode)
public TEntity CreateEntityFromDataRow<TEntity>(DataRow row)
where TEntity : IDbEntity, class
{
MethodInfo methodInfo = typeof(T).GetMethod("BuildFromDataRow");
TEntity instance = Activator.CreateInstance(typeof(TEntity)) as TEntity;
return methodInfo.Invoke(instance, new object[] { row } ) as TEntity;
}
Java 9+:
private byte[] loadPEM(String resource) throws IOException {

InputStream in = url.openStream();
String pem = new String(in.readAllBytes(), StandardCharsets.ISO_8859_1);
Pattern parse = Pattern.compile("(?m)(?s)^---*BEGIN.*---*$(.*)^---*END.*---*$.*");
String encoded = parse.matcher(pem).replaceFirst("$1");
return Base64.getMimeDecoder().decode(encoded);
}
@Test
public void test() throws Exception {
KeyFactory kf = KeyFactory.getInstance("RSA");
CertificateFactory cf = CertificateFactory.getInstance("X.509");

PublicKey pub = kf.generatePublic(new X509EncodedKeySpec(loadPEM("test.pub")));
Certificate crt = cf.generateCertificate(getClass().getResourceAsStream("test.crt"));
}
Java 8:
replace the in.readAllBytes()
call with a call to this:
byte[] readAllBytes(InputStream in) throws IOException {
ByteArrayOutputStream baos= new ByteArrayOutputStream();
byte[] buf = new byte[1024];
for (int read=0; read != -1; read = in.read(buf)) { baos.write(buf, 0, read); }
return baos.toByteArray();
}

As it was already mentioned: READONLY
does not work for <input type='checkbox'>
and <select>...</select>
.
If you have a Form
with disabled checkboxes / selects AND need them to be submitted, you can use jQuery:
$('form').submit(function(e) {
$(':disabled').each(function(e) {
$(this).removeAttr('disabled');
})
});
This code removes the disabled
attribute from all elements on submit.
Besides using ProcessBuilder
as suggested Senthil, be sure to read and implement all the recommendations of When Runtime.exec() won't.
You would want to amend the commit and then do a force push which will update the branch with the PR.
Here's how I recommend you do this:
git reset --soft HEAD^
or if it's a different commit, you would want to replace 'HEAD^' with the commit id)git commit -a -c ORIG_HEAD
The now that your branch has been updated, the Pull Request will include your changes.
Here's a link to Gits documentation where they have a pretty good example under Undo a commit and redo.
public class Example extends Activity
{
private ListView lv;
ArrayList<String> arrlist=new ArrayList<String>();
//let me assume that you are putting the values in this arraylist
//Now convert your arraylist to array
//You will get an exmaple here
//http://www.java-tips.org/java-se-tips/java.lang/how-to-convert-an-arraylist-into-an-array.html
private String arr[]=convert(arrlist);
@Override
public void onCreate(Bundle bun)
{
super.onCreate(bun);
setContentView(R.layout.main);
lv=(ListView)findViewById(R.id.lv);
lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , arr));
}
}
To further refine the accepted answer it's worth noting that if you instantiate the object with a var object = Object.create(null)
then object.hasOwnProperty(property)
will trigger a TypeError. So to be on the safe side, you'd need to call it from the prototype like this:
for (var property in object) {
if (Object.prototype.hasOwnProperty.call(object, property)) {
// do stuff
}
}
As of WPF 4.5 you can bind directly to static properties and have the binding automatically update when your property is changed. You do need to manually wire up a change event to trigger the binding updates.
public class VersionManager
{
private static String _filterString;
/// <summary>
/// A static property which you'd like to bind to
/// </summary>
public static String FilterString
{
get
{
return _filterString;
}
set
{
_filterString = value;
// Raise a change event
OnFilterStringChanged(EventArgs.Empty);
}
}
// Declare a static event representing changes to your static property
public static event EventHandler FilterStringChanged;
// Raise the change event through this static method
protected static void OnFilterStringChanged(EventArgs e)
{
EventHandler handler = FilterStringChanged;
if (handler != null)
{
handler(null, e);
}
}
static VersionManager()
{
// Set up an empty event handler
FilterStringChanged += (sender, e) => { return; };
}
}
You can now bind your static property just like any other:
<TextBox Text="{Binding Path=(local:VersionManager.FilterString)}"/>
In my case (label on a panel) I set label.AutoSize = false
and label.Dock = Fill
.
And the label text is wrapped automatically.

}
.ForEach(money =>
{
Console.WriteLine($"amount is {money.Amount}, and type is {money.Type}");

That's the job that GNU's automake/autoconf are designed to solve. You might want to investigate them.
Alternatively you can set environment variables on your different platforms and make you Makefile conditional against them.
The problem is that you are using a lower case v.
You need to set it to Value and it should fix your issue:
@Html.TextBoxFor(model => model.Destination, new { id = "txtPlace", Value= "3" })

My development server refused to display errors after upgrade to Kubuntu 16.04 - I had checked php.ini numerous times ... turned out that there was a diplay_errors = off; about 100 lines below my

Communication between controllers is done though $emit
+ $on
/ $broadcast
+ $on
methods.
So in your case you want to call a method of Controller "One" inside Controller "Two", the correct way to do this is:
app.controller('One', ['$scope', '$rootScope'
function($scope) {
$rootScope.$on("CallParentMethod", function(){
$scope.parentmethod();
});
$scope.parentmethod = function() {
// task
}
}
]);
app.controller('two', ['$scope', '$rootScope'
function($scope) {
$scope.childmethod = function() {
$rootScope.$emit("CallParentMethod", {});
}
}
]);
While $rootScope.$emit
is called, you can send any data as second parameter.
Within Crystal, you can do it by creating a formula that uses the ToNumber
function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:
If NumericText ({field}) then ToNumber ({field}) else 0
Alternatively, you might find it easier to convert the field's datatype within the query used in the report.
Setting "expires" to a past date is the standard way to delete a cookie.
Your problem is probably because the date format is not conventional. IE probably expects GMT only.
a = ["some", "thing"]
b = ["another", "thing"]
To append b
to a
and store the result in a
:
a.push(*b)
or
a += b
In either case, a
becomes:
["some", "thing", "another", "thing"]
but in the former case, the elements of b
are appended to the existing a
array, and in the latter case the two arrays are concatenated together and the result is stored in a
.
This answer is based on an article that no longer exists:
Summary of article:
"Basically, WCF is a service layer that allows you to build applications that can communicate using a variety of communication mechanisms. With it, you can communicate using Peer to Peer, Named Pipes, Web Services and so on.
You can’t compare them because WCF is a framework for building interoperable applications. If you like, you can think of it as a SOA enabler. What does this mean?
Well, WCF conforms to something known as ABC, where A is the address of the service that you want to communicate with, B stands for the binding and C stands for the contract. This is important because it is possible to change the binding without necessarily changing the code. The contract is much more powerful because it forces the separation of the contract from the implementation. This means that the contract is defined in an interface, and there is a concrete implementation which is bound to by the consumer using the same idea of the contract. The datamodel is abstracted out."
... later ...
"should use WCF when we need to communicate with other communication technologies (e,.g. Peer to Peer, Named Pipes) rather than Web Service"
Perhaps your hosting server and email server are located at same place and you don't need to go for smtp authentication. Just keep every thing default like:
$config = array(
'protocol' => '',
'smtp_host' => '',
'smtp_port' => '',
'smtp_user' => '[email protected]',
'smtp_pass' => '**********'
);
or
$config['protocol'] = '';
$config['smtp_host'] = '';
$config['smtp_port'] = ;
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'password';
it works for me.
My issue was that the 'master' branch hadn't been created locally yet.

Another way to do this solely with css:
input[type='checkbox'] {
float: left;
width: 20px;
}
input[type='checkbox'] + label {
display: block;
width: 30px;
}
Note that this forces each checkbox and its label onto a separate line, rather than only doing so only when there's overflow.

You need to compile and then link the object files like this:
gcc -c a.c
gcc -c b.c
gcc a.o b.o -o prog
I was looking for a similar solution and this is what I would suggest. In the OnTouch method, record the time for MotionEvent.ACTION_DOWN event and then for MotionEvent.ACTION_UP, record the time again. This way you can set your own threshold also. After experimenting few times you will know the max time in millis it would need to record a simple touch and you can use this in move or other method as you like.
Hope this helped. Please comment if you used a different method and solved your problem.
As an alternative to @Mark Byers' approach, you can use while True
:
guess = 50 # this should be outside the loop, I think
while True: # infinite loop
n = raw_input("\n\nTrue, False or Correct?: ")
if n == "Correct":
break # stops the loop
elif n == "True":
# etc.
To make this simple, you have two options to reapply your stash:
git stash pop

- Restore back to the saved state and leaves the stash list for possible later reuse.You can read in more detail about git stashes in this article.

I have same issue. Error message for me is not complete. But in my case, I've added generation jar with sources. By placing this code in pom.xml:

<phase>deploy</phase>
<goals>
<goal>jar</goal>

So in deploy phase I execute source:jar goal which produces jar with sources. And deploy ends with BUILD SUCCESS
How about this?
a = [['a', '1.2', '4.2'], ['b', '70', '0.03'], ['x', '5', '0']]
df = pd.DataFrame(a, columns=['one', 'two', 'three'])
df

one two three
0 a 1.2 4.2
1 b 70 0.03
2 x 5 0
df.dtypes
Out[17]:
one object
two object
three object
df[['two', 'three']] = df[['two', 'three']].astype(float)
df.dtypes
Out[19]:
one object
two float64
three float64
Because default parameters are resolved at compile time, not runtime. So the default values does not belong to the object being called, but to the reference type that it is being called through.
Update by Arkadiy: I've observed more correct behavior of System.currentTimeMillis()
on Windows 7 in Oracle Java 8. The time was returned with 1 millisecond precision. The source code in OpenJDK has not changed, so I do not know what causes the better behavior.
David Holmes of Sun posted a blog article a couple years ago that has a very detailed look at the Java timing APIs (in particular System.currentTimeMillis()
and System.nanoTime()
), when you would want to use which, and how they work internally.
Inside the Hotspot VM: Clocks, Timers and Scheduling Events - Part I - Windows
One very interesting aspect of the timer used by Java on Windows for APIs that have a timed wait parameter is that the resolution of the timer can change depending on what other API calls may have been made - system wide (not just in the particular process). He shows an example where using Thread.sleep()
will cause this resolution change.

Get rid of the escape characters before storing or manipulating the raw string:
You could change any backslashes of the path '\' to forward slashes '/' before storing them in a variable. The forward slashes don't need to be escaped:
>>> mypath = os.getcwd().replace('\\','/')
>>> os.path.exists(mypath)
True
>>>
You need to define the output parameter as an output parameter in the code with the ParameterDirection.Output
enumeration. There are numerous examples of this out there, but here's one on MSDN.
Have you tried using the "auto-fill" in Excel?
If you have an entire column of items you put the formula in the first cell, make sure you get the result you desire and then you can do the copy/paste, or use auto fill which is an option that sits on the bottom right corner of the cell.
You go to that corner in the cell and once your cursor changes to a "+", you can double-click on it and it should populate all the way down to the last entry (as long as there are no populated cells, that is).
Right click on the page and choose 'inspect element'. In the screen that opens now (the developer tools), clicking the second icon from the left @ the bottom of it opens a console, where you can type javascript. The console is linked to the current page.
In class file you can either use:
module.exports = class ClassNameHere {
print() {
console.log('In print function');
}
}
or you can use this syntax
class ClassNameHere{
print(){
console.log('In print function');
}
}
module.exports = ClassNameHere;
On the other hand to use this class in any other file you need to do these steps.
First require that file using this syntax:
const anyVariableNameHere = require('filePathHere');
Then create an object
const classObject = new anyVariableNameHere();
After this you can use classObject
to access the actual class variables

You can just implement the Map.Entry<K, V>
interface yourself:
import java.util.Map;
final class MyEntry<K, V> implements Map.Entry<K, V> {
private final K key;
private V value;
public MyEntry(K key, V value) {
this.key = key;
this.value = value;
}
@Override
public K getKey() {
return key;
}
@Override
public V getValue() {
return value;
}
@Override
public V setValue(V value) {
V old = this.value;
this.value = value;
return old;
}
}
And then use it:
Map.Entry<String, Object> entry = new MyEntry<String, Object>("Hello", 123);
System.out.println(entry.getKey());
System.out.println(entry.getValue());
Set an id to the option then use get element by id and disable it when x value has been selected..

<option value="900.0" id="900">900GB</option>
<option value="300.0" id ="300">300GB</option>
</select>
</body>
<script>
var perfType = document.getElementById("driveRPM").value;
if(perfType == "7200"){
document.getElementById("driveCapacity").value = "4000.0";
document.getElementById("4000").disabled = false;
}else{
document.getElementById("4000").disabled = true;
}

Depending on what font you're using you can set max-width
on the paragraph with a calculated value. It will not be exact, but I've found that in most cases that does not matter.
p {
max-width: calc(30em * 0.5);
}
The number you multiply with depends on what font it is, and how much a character takes up in a em square. More characters = less accurate.

Stumbled upon this thread a couple years later. In 2016, most Android devices will have API level >= 18 and should thus rely on Location.isFromMockProvider() as pointed out by Fernando.
I extensively experimented with fake/mock locations on different Android devices and distros. Unfortunately .isFromMockProvider() is not 100% reliable. Every once in a while, a fake location will not be labeled as mock. This seems to be due to some erroneous internal fusion logic in the Google Location API.
I wrote a detailed blog post about this, if you want to learn more. To summarize, if you subscribe to location updates from the Location API, then switch on a fake GPS app and print the result of each Location.toString() to the console, you will see something like this:
Notice how, in the stream of location updates, one location has the same coordinates as the others, but is not flagged as a mock and has a much poorer location accuracy.
To remedy this problem, I wrote a utility class that will reliably suppress Mock locations across all modern Android versions (API level 15 and up):
LocationAssistant - Hassle-free location updates on Android
Basically, it "distrusts" non-mock locations that are within 1km of the last known mock location and also labels them as a mock. It does this until a significant number of non-mock locations have arrived. The LocationAssistant can not only reject mock locations, but also unburdens you from most of the hassle of setting up and subscribing to location updates.
To receive only real location updates (i.e. suppress mocks), use it as follows:
public class MyActivity extends Activity implements LocationAssistant.Listener {
private LocationAssistant assistant;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
// You can specify a different accuracy and interval here.
// The last parameter (allowMockLocations) must be 'false' to suppress mock locations.
assistant = new LocationAssistant(this, this, LocationAssistant.Accuracy.HIGH, 5000, false);
}
@Override
protected void onResume() {
super.onResume();
assistant.start();
}
@Override
protected void onPause() {
assistant.stop();
super.onPause();
}
@Override
public void onNewLocationAvailable(Location location) {
// No mock locations arriving here
}
...
}
onNewLocationAvailable()
will now only be invoked with real location info. There are some more listener methods you need to implement, but in the context of your question (how to prevent GPS spoofing) this is basically it.
Of course, with a rooted OS you can still find ways of spoofing location info that are impossible for normal apps to detect.

The defaultdict solution is better. But for completeness you could also check and create empty list before the append. Add the + lines:

IMHO: object oriented programming in Python sucks quite a lot.
The method dispatching is not very straightforward, you need to know about bound/unbound instance/class (and static!) methods; you can have multiple inheritance and need to deal with legacy and new style classes (yours was old style) and know how the MRO works, properties...
In brief: too complex, with lots of things happening under the hood. Let me even say, it is unpythonic, as there are many different ways to achieve the same things.
My advice: use OOP only when it's really useful. Usually this means writing classes that implement well known protocols and integrate seamlessly with the rest of the system. Do not create lots of classes just for the sake of writing object oriented code.
Take a good read to this pages:
you'll find them quite useful.
If you really want to learn OOP, I'd suggest starting with a more conventional language, like Java. It's not half as fun as Python, but it's more predictable.
Synchronous is defined as happening at the same time.
Asynchronous is defined as not happening at the same time.
This is what causes the first confusion. Synchronous is actually what is known as parallel. While asynchronous is sequential, do this, then do that.
Now the whole problem is about modeling an asynchronous behaviour, because you've got some operation that needs the response of another before it can begin. Thus it's a coordination problem, how will you know that you can now start that operation?
The simplest solution is known as blocking.
Blocking is when you simply choose to wait for the other thing to be done and return you a response before moving on to the operation that needed it.
So if you need to put butter on toast, and thus you first need to toast the bred. The way you'd coordinate them is that you'd first toast the bred, then stare endlessly at the toaster until it pops the toast, and then you'd proceed to put butter on them.
It's the simplest solution, and works very well. There's no real reason not to use it, unless you happen to also have other things you need to be doing which don't require coordination with the operations. For example, doing some dishes. Why wait idle staring at the toaster constantly for the toast to pop, when you know it'll take a bit of time, and you could wash a whole dish while it finishes?
That's where two other solutions known respectively as non-blocking and asynchronous come into play.
Non-blocking is when you choose to do other unrelated things while you wait for the operation to be done. Checking back on the availability of the response as you see fit.
So instead of looking at the toaster for it to pop. You go and wash a whole dish. And then you peek at the toaster to see if the toasts have popped. If they havn't, you go wash another dish, checking back at the toaster between each dish. When you see the toasts have popped, you stop washing the dishes, and instead you take the toast and move on to putting butter on them.
Having to constantly check on the toasts can be annoying though, imagine the toaster is in another room. In between dishes you waste your time going to that other room to check on the toast.
Here comes asynchronous.
Asynchronous is when you choose to do other unrelated things while you wait for the operation to be done. Instead of checking on it though, you delegate the work of checking to something else, could be the operation itself or a watcher, and you have that thing notify and possibly interupt you when the response is availaible so you can proceed to the other operation that needed it.
Its a weird terminology. Doesn't make a whole lot of sense, since all these solutions are ways to create asynchronous coordination of dependent tasks. That's why I prefer to call it evented.
So for this one, you decide to upgrade your toaster so it beeps when the toasts are done. You happen to be constantly listening, even while you are doing dishes. On hearing the beep, you queue up in your memory that as soon as you are done washing your current dish, you'll stop and go put the butter on the toast. Or you could choose to interupt the washing of the current dish, and deal with the toast right away.
If you have trouble hearing the beep, you can have your partner watch the toaster for you, and come tell you when the toast is ready. Your partner can itself choose any of the above three strategies to coordinate its task of watching the toaster and telling you when they are ready.
On a final note, it's good to understand that while non-blocking and async (or what I prefer to call evented) do allow you to do other things while you wait, you don't have too. You can choose to constantly loop on checking the status of a non-blocking call, doing nothing else. That's often worse than blocking though (like looking at the toaster, then away, then back at it until its done), so a lot of non-blocking APIs allow you to transition into a blocking mode from it. For evented, you can just wait idle until you are notified. The downside in that case is that adding the notification was complex and potentially costly to begin with. You had to buy a new toaster with beep functionality, or convince your partner to watch it for you.
And one more thing, you need to realize the trade offs all three provide. One is not obviously better than the others. Think of my example. If your toaster is so fast, you won't have time to wash a dish, not even begin washing it, that's how fast your toaster is. Getting started on something else in that case is just a waste of time and effort. Blocking will do. Similarly, if washing a dish will take 10 times longer then the toasting. You have to ask yourself what's more important to get done? The toast might get cold and hard by that time, not worth it, blocking will also do. Or you should pick faster things to do while you wait. There's more obviously, but my answer is already pretty long, my point is you need to think about all that, and the complexities of implementing each to decide if its worth it, and if it'll actually improve your throughput or performance.
Edit:
Even though this is already long, I also want it to be complete, so I'll add two more points.
In our example it would be like starting the toaster, then the dishwasher, then the microwave, etc. And then waiting on any of them. Where you'd check the toaster to see if it's done, if not, you'd check the dishwasher, if not, the microwave, and around again.
I don't really understand how we got there. But when it comes to IO and Computation, synchronous and asynchronous often refer to what is better known as non-overlapped and overlapped. That is, asynchronous means that IO and Computation are overlapped, aka, happening concurrently. While synchronous means they are not, thus happening sequentially. For synchronous non-blocking, that would mean you don't start other IO or Computation, you just busy wait and simulate a blocking call. I wish people stopped misusing syncronous and asynchronous like that. So I'm not encouraging it.
Depending on your PHP configuration, this may be a easy as using:
$jsonData = json_decode(file_get_contents('https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json'));
However, if allow_url_fopen
isn't enabled on your system, you could read the data via CURL as follows:
<?php
$curlSession = curl_init();
curl_setopt($curlSession, CURLOPT_URL, 'https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json');
curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);
$jsonData = json_decode(curl_exec($curlSession));
curl_close($curlSession);
?>
Incidentally, if you just want the raw JSON data, then simply remove the json_decode

By using Constructor Injection, you assert the requirement for the dependency in a container-agnostic manner
We need the assurance from the IoC container that, before using any bean, the injection of necessary beans must be done.
In setter injection strategy, we trust the IoC container that it will first create the bean first but will do the injection right before using the bean using the setter methods. And the injection is done according to your configuration. If you somehow misses to specify any beans to inject in the configuration, the injection will not be done for those beans and your dependent bean will not function accordingly when it will be in use!
But in constructor injection strategy, container imposes (or must impose) to provide the dependencies properly while constructing the bean. This was addressed as " container-agnostic manner", as we are required to provide dependencies while creating the bean, thus making the visibility of dependency, independent of any IoC container.
Edit:
Q1: And how to prevent container from creating bean by constructor with null
values instead of missing beans?
You have no option to really miss any <constructor-arg>
(in case of Spring), because you are imposed by IoC container to provide all the constructor arguments needed to match a provided constructor for creating the bean. If you provide null
in your <constructor-arg>
intentionally. Then there is nothing IoC container can do or need to do with it!
The documentation on XML powered animations is horrible. I've searched around hours just to animate the background color of a button when pressing... The sad thing is that the animation is only one attribute away: You can use exitFadeDuration
in the selector
:
<selector xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="200">
<item android:state_pressed="true">
<shape android:tint="#3F51B5" />
</item>
<item>
<shape android:tint="#F44336" />
</item>
</selector>
Then just use it as background
for your view. No Java/Kotlin code needed.

To add new changes to a new branch and push to remote:

It goes through the object as a key-value structure. Then it will add a new property named 'Active' and a sample value for this property ('Active) to every single object inside of this object. this code can be applied for both array of objects and object of objects.
Object.keys(Results).forEach(function (key){
Object.defineProperty(Results[key], "Active", { value: "the appropriate value"});
});
As others have said, it's a new syntax to create functions.
However, this kind of functions differ from normal ones:
They bind the this
value. As explained by the spec,
An ArrowFunction does not define local bindings for
arguments
,super
,this
, ornew.target
. Any reference toarguments
,super
,this
, ornew.target
within an ArrowFunction must resolve to a binding in a lexically enclosing environment. Typically this will be the Function Environment of an immediately enclosing function.Even though an ArrowFunction may contain references to
super
, the function object created in step 4 is not made into a method by performing MakeMethod. An ArrowFunction that referencessuper
is always contained within a non-ArrowFunction and the necessary state to implementsuper
is accessible via the scope that is captured by the function object of the ArrowFunction.
They are non-constructors.
That means they have no [[Construct]] internal method, and thus can't be instantiated, e.g.
var f = a => a;
f(123); // 123
new f(); // TypeError: f is not a constructor
-(void)kundanselect
{
NSMutableArray *allControllers = [[NSMutableArray alloc] initWithArray:self.navigationController.viewControllers];
NSArray *allControllersCopy = [allControllers copy];
if ([[allControllersCopy lastObject] isKindOfClass: [kundanViewController class]])
{
[[NSNotificationCenter defaultCenter]postNotificationName:@"kundanViewControllerHide"object:nil userInfo:nil];
}
else
{
[[NSUserDefaults standardUserDefaults] setInteger:4 forKey:@"selected"];
[self performSegueWithIdentifier:@"kundansegue" sender:self];
}
}
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(ApparelsViewControllerHide) name:@"ApparelsViewControllerHide" object:nil];
I tested "jenv" and other things like setting "JAVA_HOME" without success. Now i and endet up with following solution
function setJava {
export JAVA_HOME="$(/usr/libexec/java_home -v $1)"
launchctl setenv JAVA_HOME $JAVA_HOME
sudo ln -nsf "$(dirname ${JAVA_HOME})/MacOS" /Library/Java/MacOS
java -version
}
(added to ~/.bashrc or ~/.bash.profile or ~/.zshrc)
And calling like that:
setJava 1.8
java_home will handle the wrong input. so you can't do something wrong. Maven and other stuff will pick up the right version now.
public boolean isElementDisplayed() {
return !driver.findElements(By.xpath("...")).isEmpty();
}
Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.
Shell calls to reverse (as mentioned above) are very good to debug these problems, but there are two critical conditions:
Yes, it's logical. Yes, it's also confusing because reverse will only throw the exception and won't give you any further hints.
An example of URL pattern:
url(r'^cookies/(?P<hostname>[^/]+)/(?P<url_id>\d+)/$', 'register_site.views.show_cookies', name='show_cookies'),
And then what happens in shell:
>>> from register_site.views import show_cookies
>>> reverse(show_cookies)
NoReverseMatch: Reverse for 'register_site.views.show_cookies' with arguments '()' and keyword arguments '{}' not found.
It doesn't work because I supplied no arguments.
>>> reverse('show_cookies', kwargs={'url_id':123,'hostname': 'aaa'})
'/cookies/aaa/123'
Now it worked, but...
>>> reverse('show_cookies', kwargs={'url_id':'x','hostname': 'www.dupa.com'})
NoReverseMatch: Reverse for 'show_cookies' with arguments '()' and keyword arguments '{'url_id': 'x', 'hostname': 'www.dupa.com'}' not found.
Now it didn't work because url_id didn't match the regexp (expected numeric, supplied string).
You can use reverse with both positional arguments and keyword arguments. The syntax is:
reverse(viewname, urlconf=None, args=None, kwargs=None, prefix=None, current_app=None)
As it comes to the url template tag, there's funny thing about it. Django documentation gives example of using quoted view name:
{% url 'news.views.year_archive' yearvar %}
So I used it in a similar way in my HTML template:
{% url 'show_cookies' hostname=u.hostname url_id=u.pk %}
But this didn't work for me. But the exception message gave me a hint of what could be wrong - note the double single quotes around view name:
Reverse for ''show_cookies'' with arguments...
It started to work when I removed the quotes:
{% url show_cookies hostname=u.hostname url_id=u.pk %}
And this is confusing.
Before Java 8 (versions 7 or 6) I use the new method ArgumentMatchers.anyList:
import static org.mockito.Mockito.*;
import org.mockito.ArgumentMatchers;
verify(mock, atLeastOnce()).process(ArgumentMatchers.<Bar>anyList());

When you test using class inherits unittest.TestCase you can simply use methods like:
and similar (in python documentation you find the rest).
In your example we can simply assert if mock_method.called property is False, which means that method was not called.
import unittest
from unittest import mock
import my_module
class A(unittest.TestCase):
def setUp(self):
self.message = "Method should not be called. Called {times} times!"
@mock.patch("my_module.method_to_mock")
def test(self, mock_method):
my_module.method_to_mock()
self.assertFalse(mock_method.called,
self.message.format(times=mock_method.call_count))
IE10 does not support DX filters as IE9 and earlier have done, nor does it support a prefixed version of the greyscale filter.
However, you can use an SVG overlay in IE10 to accomplish the greyscaling. Example:
img.grayscale:hover {
filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'1 0 0 0 0, 0 1 0 0 0, 0 0 1 0 0, 0 0 0 1 0\'/></filter></svg>#grayscale");
}
svg {
background:url(http://4.bp.blogspot.com/-IzPWLqY4gJ0/T01CPzNb1KI/AAAAAAAACgA/_8uyj68QhFE/s400/a2cf7051-5952-4b39-aca3-4481976cb242.jpg);
}

Not spectacular different than the answers already given, but more generic is :
sortArrayOfObjects = (arr, key) => {
return arr.sort((a, b) => {
return a[key] - b[key];
});
};
sortArrayOfObjects(yourArray, "distance");
string path = HttpContext.Current.Server.MapPath("~/App_Data/somedata.xml");
string path = Server.MapPath("~/App_Data/somedata.xml");
You can, once you escape the HTML correctly. This page shows what needs to be done.
If using PHP, you could use json_encode()
Hope this helps :)
the log will output to a new line every time it is called, in chrome if it's the same it will just keep a count (not sure about other browsers). You want to collect the number of stars per line then output that after the inner loop has run
for (var i = 5; i >= 1; i--) {_x000D_
var ouput = "";_x000D_
for (var j = i; j >= 1; j--) {_x000D_

Simple solution, just one line..
var obj = {
"set1": [1, 2, 3],
"set2": [4, 5, 6, 7, 8],
"set3": [9, 10, 11, 12]
};
obj = Object.values(obj);
obj[1]....
You can test if it actually is in the PATH, if you open a cmd and type in chromedriver
(assuming your chromedriver executable is still named like this) and hit Enter. If Starting ChromeDriver 2.15.322448
is appearing, the PATH is set appropriately and there is something else going wrong.
Alternatively you can use a direct path to the chromedriver like this:
driver = webdriver.Chrome('/path/to/chromedriver')
So in your specific case:
driver = webdriver.Chrome("C:/Users/michael/Downloads/chromedriver_win32/chromedriver.exe")
just you need to use couple of methods for this, that's it!
var strVale = "130,235,342,124";
var resultArray = strVale.split(',').map(function(strVale){return Number(strVale);});
the output will be the array of numbers.
Simple:
homestead destroy
homestead up
Edit (Not as simple as first thought):
The issue was that new versions of homestead use php7.0
and some other stuff. To avoid this mess up make sure you set the verison
in Homestead.yml
:

There is one link where it elaborated very well & solution is also given. Try it if you got proper solution please post here so other can understand. Given solution is ok then like the post so other can try these solution.
for you reference original link :- https://bensonxion.wordpress.com/2012/05/07/serializing-an-ienumerable-produces-collection-was-modified-enumeration-operation-may-not-execute/
When we use .Net Serialization classes to serialize an object where its definition contains an Enumerable type, i.e. collection, you will be easily getting InvalidOperationException saying "Collection was modified; enumeration operation may not execute" where your coding is under multi-thread scenarios. The bottom cause is that serialization classes will iterate through collection via enumerator, as such, problem goes to trying to iterate through a collection while modifying it.
First solution, we can simply use lock as a synchronization solution to ensure that the operation to the List object can only be executed from one thread at a time. Obviously, you will get performance penalty that if you want to serialize a collection of that object, then for each of them, the lock will be applied.
Well, .Net 4.0 which makes dealing with multi-threading scenarios handy. for this serializing Collection field problem, I found we can just take benefit from ConcurrentQueue(Check MSDN)class, which is a thread-safe and FIFO collection and makes code lock-free.
Using this class, in its simplicity, the stuff you need to modify for your code are replacing Collection type with it, use Enqueue to add an element to the end of ConcurrentQueue, remove those lock code. Or, if the scenario you are working on do require collection stuff like List, you will need a few more code to adapt ConcurrentQueue into your fields.
BTW, ConcurrentQueue doesnât have a Clear method due to underlying algorithm which doesnât permit atomically clearing of the collection. so you have to do it yourself, the fastest way is to re-create a new empty ConcurrentQueue for a replacement.
This problem appear if two software use same port for connecting to the server
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse or your Software.
The only sure shot way to do this is to call CreateFile()
on all \\.\Physicaldiskx
where x is from 0 to 15 (16 is maximum number of disks allowed). Check the returned handle value. If invalid check GetLastError()
for ERROR_FILE_NOT_FOUND. If it returns anything else then the disk exists but you cannot access it for some reason.
It's fatal. The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake. This bypasses the normal half-closed state transition. I like this description:
"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur.
Java mysteriously broke on my work PC after a security patch was pushed out to us, giving this error whenever you tried to run a Java program. Somehow the 'lib' subdirectory of the Java 7 install had vanished! It might have been related to having multiple Java versions installed simultaneously.
If you're getting this error there are basically two things that could be wrong:
1) Your Java installation is broken. If the file/directory it's complaining about doesn't exist, uninstall and reinstall the JRE and then it should be there. This fixed it for me.
2) If the files are there, your PATH is somehow incorrect or pointing at an old/broken Java install. In this case you either need to fix your PATH to point to the correct java.exe/javaw.exe, or use a fully qualified path. So instead of:
java <whatever>
Use
c:\<full path to correct JRE>\bin\java.exe <whatever>
3) If your PATH is correct and files are there and it's still failing, the path could be getting truncated because it is too long. see: Running Java gives "Error: could not open `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg'" .
Here is a demo. Use position:fixed; top:0; left:0;
so the header always stay on top.
?#header {
background:red;
height:50px;
width:100%;
position:fixed;
top:0;
left:0;
}.scroller {
height:300px;
overflow:scroll;
}
I think the problem is that in the debug visual studio don't use the normal exeName.
it use indtead "NameApplication".host.exe
so the name of the config file is "NameApplication".host.exe.config and not "NameApplication".exe.config
and after the application close - it return to the back app.config
so if you check the wrong file or you check on the wrong time you will see that nothing changed.
You have to change
loadNavItems() {
this.navItems = this.http.get("../data/navItems.json");
console.log(this.navItems);
}
for
loadNavItems() {
this.navItems = this.http.get("../data/navItems.json")
.map(res => res.json())
.do(data => console.log(data));
//This is optional, you can remove the last line
// if you don't want to log loaded json in
// console.
}
Because this.http.get
returns an Observable<Response>
and you don't want the response, you want its content.
The console.log
shows you an observable, which is correct because navItems contains an Observable<Response>
.
In order to get data properly in your template, you should use async
pipe.
<app-nav-item-comp *ngFor="let item of navItems | async" [item]="item"></app-nav-item-comp>
This should work well, for more informations, please refer to HTTP Client documentation

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path. As mention below exePath mean folder where exe placed along with it's references files.
Exe application creating any temporaray file so it will create in folder mention in processBuilder.directory(...)
**
ProcessBuilder processBuilder = new ProcessBuilder(arguments);
processBuilder.redirectOutput(Redirect.PIPE);
processBuilder.directory(new File(exePath));
process = processBuilder.start();
int waitFlag = process.waitFor();// Wait to finish application execution.
if (waitFlag == 0) {
...
int returnVal = process.exitValue();

Use Properties.loadFromXML(InputStream)
. There's no need for external libs.
Better than a messy code (since maintainability and design are your concern), it is preferable not to use long strings.
Start by reading xml properties:
InputStream fileIS = YourClass.class.getResourceAsStream("MultiLine.xml");
Properties prop = new Properies();
prop.loadFromXML(fileIS);
then you can use your multiline string in a more maintainable way...
static final String UNIQUE_MEANINGFUL_KEY = "Super Duper UNIQUE Key";
prop.getProperty(UNIQUE_MEANINGFUL_KEY) // "\n MEGA\n LONG\n..."
MultiLine.xml` gets located in the same folder YourClass:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<entry key="Super Duper UNIQUE Key">
MEGA
LONG
MULTILINE
</entry>
</properties>
PS.: You can use <![CDATA["
... "]]>
for xml-like string.
I regularly use IntelliJ, PHPStorm and WebStorm. Would love to only use IntelliJ. As pointed out by the vendor the "Open Directory" functionality not being in IntelliJ is painful.
Now for the rub part; I have tried using IntelliJ as my single IDE and have found performance to be terrible compared to the lighter weight versions. Intellisense is almost useless in IntelliJ compared to WebStorm.
Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.
So, first build a list, then use pickle.dump
to send it to a file...

When console.log(this.ev)
is executed after this.fetchEvent();
, this doesn't mean the fetchEvent()
call is done, this only means that it is scheduled. When console.log(this.ev)
is executed, the call to the server is not even made and of course has not yet returned a value.
Change fetchEvent()
to return a Promise
fetchEvent(){
return this._apiService.get.event(this.eventId).then(event => {
this.ev = event;
console.log(event); // Has a value
console.log(this.ev); // Has a value
});
}
change ngOnInit()
to wait for the Promise
to complete
ngOnInit() {
this.fetchEvent().then(() =>
console.log(this.ev)); // Now has value;
}
This actually won't buy you much for your use case.
My suggestion: Wrap your entire template in an <div *ngIf="isDataAvailable"> (template content) </div>
and in ngOnInit()
isDataAvailable:boolean = false;
ngOnInit() {
this.fetchEvent().then(() =>
this.isDataAvailable = true); // Now has value;
}
The .NET numeric primitive types do not share any common interface that would allow them to be used for calculations. It would be possible to define your own interfaces (e.g. ISignedWholeNumber
) which would perform such operations, define structures which contain a single Int16
, Int32
, etc. and implement those interfaces, and then have methods which accept generic types constrained to ISignedWholeNumber
, but having to convert numeric values to your structure types would likely be a nuisance.
An alternative approach would be to define static class Int64Converter<T>
with a static property bool Available {get;};
and static delegates for Int64 GetInt64(T value)
, T FromInt64(Int64 value)
, bool TryStoreInt64(Int64 value, ref T dest)
. The class constructor could use be hard-coded to load delegates for known types, and possibly use Reflection to test whether type T
implements methods with the proper names and signatures (in case it's something like a struct which contains an Int64
and represents a number, but has a custom ToString()
method). This approach would lose the advantages associated with compile-time type-checking, but would still manage to avoid boxing operations and each type would only have to be "checked" once. After that, operations associated with that type would be replaced with a delegate dispatch.

Apart from the previous use cases, you can also use Docker Compose to create directories in case you want to make new dummy folders on docker-compose up
:
volumes:
- .:/ftp/
- /ftp/node_modules
- /ftp/files
printf("%.2f", 37.777779);
If you want to write to C-string:
char number[24]; // dummy size, you should take care of the size!
sprintf(number, "%.2f", 37.777779);
I think using the matrix.at<type>(x,y)
is not the best way to iterate trough a Mat object!
If I recall correctly matrix.at<type>(x,y)
will iterate from the beginning of the matrix each time you call it(I might be wrong though).
I would suggest using cv::MatIterator_
cv::Mat someMat(1, 4, CV_64F, &someData);;
cv::MatIterator_<double> _it = someMat.begin<double>();
for(;_it!=someMat.end<double>(); _it++){
std::cout << *_it << std::endl;
}
If you are just looping through 10k rows in column A, then dump the row into a variant array and then loop through that.
You can then either add the elements to a new array (while adding rows when needed) and using Transpose() to put the array onto your range in one move, or you can use your iterator variable to track which row you are on and add rows that way.
Dim i As Long
Dim varray As Variant
varray = Range("A2:A" & Cells(Rows.Count, "A").End(xlUp).Row).Value
For i = 1 To UBound(varray, 1)
' do stuff to varray(i, 1)
Next
Here is an example of how you could add rows after evaluating each cell. This example just inserts a row after every row that has the word "foo" in column A. Not that the "+2" is added to the variable i during the insert since we are starting on A2. It would be +1 if we were starting our array with A1.
Sub test()
Dim varray As Variant
Dim i As Long
varray = Range("A2:A10").Value
'must step back or it'll be infinite loop
For i = UBound(varray, 1) To LBound(varray, 1) Step -1
'do your logic and evaluation here
If varray(i, 1) = "foo" Then
'not how to offset the i variable
Range("A" & i + 2).EntireRow.Insert
End If
Next
End Sub

If you are using a Form Control
, you can get the same property as ActiveX
by using OLEFormat.Object
property of the Shape Object
. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.
Dim opt As OptionButton
With Sheets("Sheet1") ' Try to be always explicit
Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With
But then again, you really don't need to know the value.
If you use Form Control
, you associate a Macro
or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.
For example you have 2 Form Control
Option Buttons.
Sub CheckOptions()
Select Case Application.Caller
Case "Option Button 1"
' Action for option button 1
Case "Option Button 2"
' Action for option button 2
End Select
End Sub
In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller
.
This way, no need to check whether the option button value is true or false.
You just can put your query as a subquery:
SELECT avg(count)
FROM
(
SELECT COUNT (*) AS Count
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time )
FROM Table B
WHERE (B.Id = T.Id))
GROUP BY T.Grouping
) as counts
Edit: I think this should be the same:
SELECT count(*) / count(distinct T.Grouping)
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time)
FROM Table B
WHERE (B.Id = T.Id))
Version 2.11+ use the following:
git stash list
git stash apply n
n is the number stash@{12}
You need to remove the static
from your accessor methods - these methods need to be instance methods and access the instance variables
public class IDCard {
public String name, fileName;
public int id;
public IDCard(final String name, final String fileName, final int id) {
this.name = name;
this.fileName = fileName
this.id = id;
}
public String getName() {
return name;
}
}
You can the create an IDCard
and use the accessor like this:
final IDCard card = new IDCard();
card.getName();
Each time you call new
a new instance of the IDCard
will be created and it will have it's own copies of the 3 variables.
If you use the static
keyword then those variables are common across every instance of IDCard
.
A couple of things to bear in mind:
name
not Name
.px
? PixelsAll of these answers seem to be incorrect. Contrary to intuition, in CSS the px
is not pixels. At least, not in the simple physical sense.
Read this article from the W3C, EM, PX, PT, CM, IN…, about how px
is a "magical" unit invented for CSS. The meaning of px
varies by hardware and resolution. (That article is fresh, last updated 2014-10.)
My own way of thinking about it: 1 px is the size of a thin line intended by a designer to be barely visible.
To quote that article:
The px unit is the magic unit of CSS. It is not related to the current font and also not related to the absolute units. The px unit is defined to be small but visible, and such that a horizontal 1px wide line can be displayed with sharp edges (no anti-aliasing). What is sharp, small and visible depends on the device and the way it is used: do you hold it close to your eyes, like a mobile phone, at arms length, like a computer monitor, or somewhere in between, like a book? The px is thus not defined as a constant length, but as something that depends on the type of device and its typical use.
To get an idea of the appearance of a px, imagine a CRT computer monitor from the 1990s: the smallest dot it can display measures about 1/100th of an inch (0.25mm) or a little more. The px unit got its name from those screen pixels.
Nowadays there are devices that could in principle display smaller sharp dots (although you might need a magnifier to see them). But documents from the last century that used px in CSS still look the same, no matter what the device. Printers, especially, can display sharp lines with much smaller details than 1px, but even on printers, a 1px line looks very much the same as it would look on a computer monitor. Devices change, but the px always has the same visual appearance.
That article gives some guidance about using pt
vs px
vs em
, to answer this Question.
Update June 2016
Felt compelled to add an answer having seen far too many SOF answers with dated or inadequate answers to very common problem - a good library and some solid example usage for both parse
and format
operations.
Use org.apache.httpcomponents.httpclient library. The library contains this org.apache.http.client.utils.URLEncodedUtils class utility.
For example, it is easy to download this dependency from Maven:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5</version>
</dependency>
For my purposes I only needed to parse
(read from query string to name-value pairs) and format
(read from name-value pairs to query string) query strings. However, there are equivalents for doing the same with a URI (see commented out line below).
// Required imports
import org.apache.http.NameValuePair;
import org.apache.http.client.utils.URLEncodedUtils;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.nio.charset.StandardCharsets;
// code snippet
public static void parseAndFormatExample() throws UnsupportedEncodingException {
final String queryString = "nonce=12345&redirectCallbackUrl=http://www.bbc.co.uk";
System.out.println(queryString);
// => nonce=12345&redirectCallbackUrl=http://www.bbc.co.uk
final List<NameValuePair> params =
URLEncodedUtils.parse(queryString, StandardCharsets.UTF_8);
// List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), "UTF-8");
for (final NameValuePair param : params) {
System.out.println(param.getName() + " : " + param.getValue());
// => nonce : 12345
// => redirectCallbackUrl : http://www.bbc.co.uk
}
final String newQueryStringEncoded =
URLEncodedUtils.format(params, StandardCharsets.UTF_8);
// decode when printing to screen
final String newQueryStringDecoded =
URLDecoder.decode(newQueryStringEncoded, StandardCharsets.UTF_8.toString());
System.out.println(newQueryStringDecoded);
// => nonce=12345&redirectCallbackUrl=http://www.bbc.co.uk
}
This library did exactly what I needed and was able to replace some hacked custom code.
In Eclipse, I had to use New > Other > JUnit > Junit Test
. A Java class created with the exact same text gave me the error, perhaps because it was using JUnit 3.x.

essentially the shadow is the box shape just offset behind the actual box. in order to hide portions of the shadow, you need to create additional divs and set their z-index above the shadowed box so that the shadow is not visible.
If you'd like to have extremely specific control over your shadows, build them as images and created container divs with the right amount of padding and margins.. then use the png fix to make sure the shadows render properly in all browsers
This looks similar to How do I get github to default to ssh and not https for new repositories. Probably it's worth trying to switch from http protocol to ssh:
$ git remote add origin [email protected]:username/project.git
You can, under certain circumstances.
But the fact that you consider this is a strong sign that there is something wrong with your architecture: Primary keys should be pure technical and carry no business meaning whatsoever. So there should never be the need to change them.

In Expression Language you can just use the ==
or eq
operator to compare object values. Behind the scenes they will actually use the Object#equals()
. This way is done so, because until with the current EL 2.1 version you cannot invoke methods with other signatures than standard getter (and setter) methods (in the upcoming EL 2.2 it would be possible).
So the particular line
<c:when test="${lang}.equals(${pageLang})">
should be written as (note that the whole expression is inside the {
and }
)
<c:when test="${lang == pageLang}">
or, equivalently
<c:when test="${lang eq pageLang}">
Both are behind the scenes roughly interpreted as
jspContext.findAttribute("lang").equals(jspContext.findAttribute("pageLang"))
If you want to compare constant String
values, then you need to quote it
<c:when test="${lang == 'en'}">
or, equivalently
<c:when test="${lang eq 'en'}">
which is behind the scenes roughly interpreted as
jspContext.findAttribute("lang").equals("en")
Element.prototype.getA = function (a) {
if (a) {
return this.getAttribute(a);
} else {
var o = {};
for(let a of this.attributes){
o[a.name]=a.value;
}
return o;
}
}
having <div id="mydiv" a='1' b='2'>...</div>
can use
mydiv.getA() // {id:"mydiv",a:'1',b:'2'}
Try marginTop
in place of margin-top
, eg:
$("#ActionBox").css("marginTop", foo);
BigDecimal can be used, good explanation of why to not use Float or Double can be seen here: Why not use Double or Float to represent currency?

Find your amended commits by:
git log --reflog
Note: You may add --patch
to see the body of the commits for clarity. Same as git reflog
.
then reset your HEAD to any previous commit at the point it was fine by:
git reset SHA1 --hard
Note: Replace SHA1 with your real commit hash. Also note that this command will lose any uncommitted changes, so you may stash them before. Alternatively, use --soft
instead to retain the latest changes and then commit them.
Then cherry-pick the other commit that you need on top of it:
git cherry-pick SHA1
If you're already using jQuery, try html()
.
$('<div>').text('<script>alert("gotcha!")</script>').html()
// "<script>alert("gotcha!")</script>"
An in-memory text node is instantiated, and html()
is called on it.
It's ugly, it wastes a bit of memory, and I have no idea if it's as thorough as something like the he
library but if you're already using jQuery, maybe this is an option for you.
Taken from blog post Encode HTML entities with jQuery by Felix Geisendörfer.
Just in case someone else runs into this problem I solved it by the following
brew update && brew upgrade # installs libpng 1.6
This caused an error with other packages requiring 1.5 which they were built with, so I linked it:
cd /usr/local/lib/
ln -s ../Cellar/libpng/1.5.18/lib/libpng15.15.dylib
Now they are both living in harmony and side by side for the different packages. It would be better to rebuild the packages that depend on 1.5, but this works as a quick bandage fix.
Your username shouldn't be an email address, but your GitHub user account: pete
.
And your password should be your GitHub account password.
You actually can set your username directly in the remote url, in order for Git to request only your password:
cd C:\Users\petey_000\rails_projects\first_app
git remote set-url origin https://[email protected]/pete/first_app
And you need to create the fist_app
repo on GitHub first: make sure to create it completely empty, or, if you create it with an initial commit (including a README.md
, a license file and a .gitignore
file), then do a git pull first, before making your git push
.
1 line solution in Java 8:
public Date getCurrentUtcTime() {
return Date.from(Instant.now());
}
Use cURL:
*/5 * * * * curl http://example.com/check/
You can use the code below if you dont want to use jQuery UI or any third party pluggin. It's only plain jQuery.

has higher precedence than &
. You might want to wrap your operations in ()
to specify how you want your operands to bind to the operators.
((a[0] & 1) == 0)
Similarly for all parts of the if
condition.
I did mine using regular expressions, since I wanted to preserve a relative path and not use add the addClass function. I just wanted to make it convoluted, lol.
$(".travelinfo-btn").click(
function() {
$("html, body").animate({scrollTop: $(this).offset().top}, 200);
var bgImg = $(this).css('background-image')
var bgPath = bgImg.substr(0, bgImg.lastIndexOf('/')+1)
if(bgImg.match(/collapse/)) {
$(this).stop().css('background-image', bgImg.replace(/collapse/,'expand'));
$(this).next(".travelinfo-item").stop().slideToggle(400);
} else {
$(this).stop().css('background-image', bgImg.replace(/expand/,'collapse'));

The following definition might be more efficient than the first solution proposed
def new_list_from_intervals(original_list, *intervals):
n = sum(j - i for i, j in intervals)
new_list = [None] * n
index = 0
for i, j in intervals :
for k in range(i, j) :
new_list[index] = original_list[k]
index += 1
return new_list
then you can use it like below
new_list = new_list_from_intervals(original_list, (0,2), (4,5), (6, len(original_list)))
I have been working on that subject for quite a long time... and made my own library which you will need to source in your main script. See libopt4shell and cd2mpc for an example. Hope it helps !
Because SQL Server performs integer division. Try this:
select 1 * 1.0 / 3
This is helpful when you pass integers as params.
select x * 1.0 / y
Don't really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don't need to hold all the data in memory at once (This can be faster or slower depending on the library/use case)
One of the possible implementations:
File file = new File("userdata.xml");
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse(file);
String usr = document.getElementsByTagName("user").item(0).getTextContent();
String pwd = document.getElementsByTagName("password").item(0).getTextContent();
when used with the XML content:
<credentials>
<user>testusr</user>
<password>testpwd</password>
</credentials>
results in "testusr"
and "testpwd"
getting assigned to the usr
and pwd
references above.
Using javascript seems to be unnecessary if you choose CSS3.
By using :before
selector, you can do this in two lines of CSS. (no script involved).
Another advantage of this approach is that it does not rely on <label>
tag and works even it is missing.
Note: in browsers without CSS3 support, checkboxes will look normal. (backward compatible).
input[type=checkbox]:before { content:""; display:inline-block; width:12px; height:12px; background:red; }
input[type=checkbox]:checked:before { background:green; }?

Some more detail for completeness in case it helps someone...
Note that the most common reason for this exception these days is attempting to load a 32 bit-specific (/platform:x86
) DLL into a process that is 64 bit or vice versa (viz. load a 64 bit-specific (/platform:x64
) DLL into a process that is 32 bit). If your platform
is non-specific (/platform:AnyCpu
), this won't arise (assuming no referenced dependencies are of the wrong bitness).
In other words, running:
%windir%\Microsoft.NET\Framework\v2.0.50727\installutil.exe
or:
%windir%\Microsoft.NET\Framework64\v2.0.50727\installutil.exe
will not work (substitute in other framework versions: v1.1.4322
(32-bit only, so this issue doesn't arise) and v4.0.30319
as desired in the above).
Obviously, as covered in the other answer, one will also need the .NET version number of the installutil
you are running to be >= (preferably =) that of the EXE/DLL file you are running the installer of.
Finally, note that in Visual Studio 2010, the tooling will default to generating x86 binaries (rather than Any CPU as previously).
Complete details of System.BadImageFormatException (saying the only cause is mismatched bittedness is really a gross oversimplification!).
Another reason for a BadImageFormatException
under an x64 installer is that in Visual Studio 2010, the default .vdproj
Install Project type generates a 32-bit InstallUtilLib
shim, even on an x64 system (Search for "64-bit managed custom actions throw a System.BadImageFormatException exception" on the page).
This is not how you do things in Java. There are no dynamic variables in Java. Java variables have to be declared in the source code1.
Depending on what you are trying to achieve, you should use an array, a List
or a Map
; e.g.
int n[] = new int[3];
for (int i = 0; i < 3; i++) {
n[i] = 5;
}
List<Integer> n = new ArrayList<Integer>();
for (int i = 1; i < 4; i++) {
n.add(5);
}
Map<String, Integer> n = new HashMap<String, Integer>();
for (int i = 1; i < 4; i++) {
n.put("n" + i, 5);
}
It is possible to use reflection to dynamically refer to variables that have been declared in the source code. However, this only works for variables that are class members (i.e. static and instance fields). It doesn't work for local variables. See @fyr's "quick and dirty" example.
However doing this kind of thing unnecessarily in Java is a bad idea. It is inefficient, the code is more complicated, and since you are relying on runtime checking it is more fragile. And this is not "variables with dynamic names". It is better described as dynamic access to variables with static names.
1 - That statement is slightly inaccurate. If you use BCEL or ASM, you can "declare" the variables in the bytecode file. But don't do it! That way lies madness!
Building slightly upon the answers here, I've wrapped this process up as a simple Bash script, which could of course be used as a Git alias as well.
The important addition to me is that this prompts me to run unit tests before committing and passes in the current branch name by default.
$ git_push_new_branch.sh
Have you run your unit tests yet? If so, pass OK or a branch name, and try again

It is worth mentioning that one can check the characters in the string against Unicode categories - numbers, uppercase, lowercase, currencies and more. Here are two examples checking for numbers in a string using Linq:
var containsNumbers = s.Any(Char.IsNumber);
var isNumber = s.All(Char.IsNumber);
For clarity, the syntax above is a shorter version of:
var containsNumbers = s.Any(c=>Char.IsNumber(c));
var isNumber = s.All(c=>Char.IsNumber(c));
Link to unicode categories on MSDN:
It's in org.apache.spark.sql.DataFrame
for sort
method:
df.sort($"col1", $"col2".desc)
Note $
and .desc
inside sort
for the column to sort the results by.
In my case (the same problem) helped to add -NoProfile in task action command arguments and check checkbox "Run with highest privileges", because on my server UAC is on (active).

Get this error at the time of adding Node in my Angular project -
TSError: ? Unable to compile TypeScript: (path)/base.api.ts:19:13 - error TS2564: Property 'apiRoot Path' has no initializer and is not definitely assigned in the constructor.
private apiRootPath: string;
Solution -
Added "strictPropertyInitialization": false
in 'compilerOptions' of tsconfig.json.
my package.json -
"dependencies": {
...
"@angular/common": "~10.1.3",
"@types/express": "^4.17.9",
"express": "^4.17.1",
...
}
I put this in my makefile, right the next line after adb install ...
adb shell monkey -p `cat .identifier` -c android.intent.category.LAUNCHER 1
For this to work there must be a .identifier file with the app's bundle identifier in it, like com.company.ourfirstapp
No need to hunt activity name.
