android:textColorHint="#FFFFFF" sometime works and sometime doesnt. For me below solution works perfectly
Try The Below Code It Works In your XML file and TextLabel theme is defined in style.xml
<android.support.design.widget.TextInputLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:theme="@style/MyTextLabel">
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Floating Label"
android:id="@+id/edtText"/>
</android.support.design.widget.TextInputLayout>
In Styles Folder TextLabel Code
<style name="MyTextLabel" parent="TextAppearance.AppCompat">
<!-- Hint color and label color in FALSE state -->
<item name="android:textColorHint">@color/Color Name</item>
<!--The size of the text appear on label in false state -->
<item name="android:textSize">20sp</item>
<!-- Label color in TRUE state and bar color FALSE and TRUE State -->
<item name="colorAccent">@color/Color Name</item>
<item name="colorControlNormal">@color/Color Name</item>
<item name="colorControlActivated">@color/Color Name</item>
</style>
If you just want to change the color of label in false state then colorAccent , colorControlNormal and colorControlActivated are not required
Setup: 32-bit Windows 7
Context: Installed a PCI-GPIB driver that I was unable to communicate through due to the aforementioned issue.
Short Answer: Reinstall the driver.
Long Answer: I also used Dependency Walker, which identified several missing dependency modules. Immediately, I thought that it must have been a botched driver installation. I didn't want to check and restore each missing file.
The fact that I was unable to find the uninstaller under Programs and Features of the Control Panel is another indicator of bad installation. I had to manually delete a couple of *.dll in \system32 and registry keys to allow for driver re-installation.
Issue fixed.
The unexpected part was that not all dependency modules were resolved. Nevertheless, the *.dll of interest can now be referenced.
You are confusing a Mock
with a Spy
.
In a mock all methods are stubbed and return "smart return types". This means that calling any method on a mocked class will do nothing unless you specify behaviour.
In a spy the original functionality of the class is still there but you can validate method invocations in a spy and also override method behaviour.
What you want is
MyProcessingAgent mockMyAgent = Mockito.spy(MyProcessingAgent.class);
A quick example:
static class TestClass {
public String getThing() {
return "Thing";
}
public String getOtherThing() {
return getThing();
}
}
public static void main(String[] args) {
final TestClass testClass = Mockito.spy(new TestClass());
Mockito.when(testClass.getThing()).thenReturn("Some Other thing");
System.out.println(testClass.getOtherThing());
}
Output is:
Some Other thing
NB: You should really try to mock the dependencies for the class being tested not the class itself.
The only way I could get this to work is to pass the JSON as a string and then deserialise it using JavaScriptSerializer.Deserialize<T>(string input)
, which is pretty strange if that's the default deserializer for MVC 4.
My model has nested lists of objects and the best I could get using JSON data is the uppermost list to have the correct number of items in it, but all the fields in the items were null.
This kind of thing should not be so hard.
$.ajax({
type: 'POST',
url: '/Agri/Map/SaveSelfValuation',
data: { json: JSON.stringify(model) },
dataType: 'text',
success: function (data) {
[HttpPost]
public JsonResult DoSomething(string json)
{
var model = new JavaScriptSerializer().Deserialize<Valuation>(json);
Try this:
find . -name "*.pdf" -type f -exec cp {} ./pdfsfolder \;
if you are using heroku, be sure you did not forget to "heroku container:login" before pushing.
Here is the answer in Razor syntax
<table border="1" cellpadding="5">
<thead>
<tr>
@foreach (System.Data.DataColumn col in Model.Columns)
{
<th>@col.Caption</th>
}
</tr>
</thead>
<tbody>
@foreach(System.Data.DataRow row in Model.Rows)
{
<tr>
@foreach (var cell in row.ItemArray)
{
<td>@cell.ToString()</td>
}
</tr>
}
</tbody>
</table>
You can also use the excellent URI.js library by Rodney Rehm. Here's how:-
var qs = URI('www.mysite.com/default.aspx?dest=aboutus.aspx').query(true); // == { dest : 'aboutus.aspx' }
alert(qs.dest); // == aboutus.aspx
And to parse the query string of current page:-
var $_GET = URI(document.URL).query(true); // ala PHP
alert($_GET['dest']); // == aboutus.aspx
If you already know what types to expect (for example, when a method returns a union type), then you can use type guards.
For example, for primitive types you can use a typeof guard:
if (typeof thing === "number") {
// Do stuff
}
For complex types you can use an instanceof guard:
if (thing instanceof Array) {
// Do stuff
}
In Excel workbook - Select the Cell-goto Format Cells - Number - Custom - in the Type box type as shows (0.00%)
To expand on my comment.
You can validate on the command line using php -l [filename]
, which does a syntax check only (lint). This will depend on your php.ini error settings, so you can edit you php.ini or set the error_reporting in the script.
Here's an example of the output when run on a file containing:
<?php
echo no quotes or semicolon
Results in:
PHP Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in badfile.php on line 2
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in badfile.php on line 2
Errors parsing badfile.php
I suggested you build your own validator.
A simple page that allows you to upload a php file. It takes the uploaded file runs it through php -l
and echos the output.
Note: this is not a security risk it does not execute the file, just checks for syntax errors.
Here's a really basic example of creating your own:
<?php
if (isset($_FILES['file'])) {
echo '<pre>';
passthru('php -l '.$_FILES['file']['tmp_name']);
echo '</pre>';
}
?>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit"/>
</form>
String s = "";
s.length();
String s = null;
s.length();
A reference to an empty string ""
points to an object in the heap - so you can call methods on it.
But a reference pointing to null
has no object to point in the heap and thus you'll get a NullPointerException
.
You could create a user form:
For an array of strings to a comma-separated string:
let months = ["January","Feb"];
let monthsString = months.join(", ");
UIAlertview *alt = [[UIAlertView alloc]initWithTitle:@"\n\n\n" message:nil delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
UILabel *lbl1 = [[UILabel alloc]initWithFrame:CGRectMake(25,17, 100, 30)];
lbl1.text=@"User Name";
UILabel *lbl2 = [[UILabel alloc]initWithFrame:CGRectMake(25, 60, 80, 30)];
lbl2.text = @"Password";
UITextField *username=[[UITextField alloc]initWithFrame:CGRectMake(130, 17, 130, 30)];
UITextField *password=[[UITextField alloc]initWithFrame:CGRectMake(130, 60, 130, 30)];
lbl1.textColor = [UIColor whiteColor];
lbl2.textColor = [UIColor whiteColor];
[lbl1 setBackgroundColor:[UIColor clearColor]];
[lbl2 setBackgroundColor:[UIColor clearColor]];
username.borderStyle = UITextBorderStyleRoundedRect;
password.borderStyle = UITextBorderStyleRoundedRect;
[alt addSubview:lbl1];
[alt addSubview:lbl2];
[alt addSubview:username];
[alt addSubview:password];
[alt show];
Assume that you have MyPayments class like
public class Mypayment
{
public int year { get; set; }
public string month { get; set; }
public string price { get; set; }
public bool ispaid { get; set; }
}
and you have a list of MyPayments
public List<Mypayment> mypayments { get; set; }
and you want group the list by year. You can use linq like this:
List<List<Mypayment>> mypayments = (from IGrouping<int, Mypayment> item in yearGroup
let mypayments1 = (from _payment in UserProjects.mypayments
where _payment.year == item.Key
select _payment).ToList()
select mypayments1).ToList();
Two methods:
<div>
that is position: absolute;
before #main
and the same height as #main
, then apply the background-image and opacity: 0.2; filter: alpha(opacity=20);
.There are a lot of great answers for this issue but I have a noobie answer.
I found that I accidentally added the same Script in two places and it was trying to bind twice. So before you pull your hair out on a simple mistake, make sure you check for this issue.
You can compare for exactly the same type using:
class A {
}
var a = new A();
var typeOfa = a.GetType();
if (typeOfa == typeof(A)) {
}
typeof returns the Type object from a given class.
But if you have a type B, that inherits from A, then this comparison is false. And you are looking for IsAssignableFrom.
class B : A {
}
var b = new B();
var typeOfb = b.GetType();
if (typeOfb == typeof(A)) { // false
}
if (typeof(A).IsAssignableFrom(typeOfb)) { // true
}
-mmin is for minutes.
Try looking at the man page.
man find
for more types.
An old question but still relevant today....due to so many developers in the enterprise space still using it.
My work involves designing and developing IoT (Internet of Things) solutions. Which includes developing code for small embedded devices that communicate with the Cloud.
It is clear REST is now widely accepted and useful, and pretty much the defacto standard for the web, even Microsoft has REST support included throughout Azure. If I needed to rely on SOAP I could not do what I need to do, as is just too big, bulky and annoying for small embedded devices.
REST is simple and clean and small. Making it ideal for small embedded devices. I always scream when I am working with a web developer who sends me a WSDLs. As I will have to begin an education campaign about why this just isn't going to work and why they are going to have to learn REST.
The advantage of Java 1.8 forEach method over 1.7 Enhanced for loop is that while writing code you can focus on business logic only.
forEach method takes java.util.function.Consumer object as an argument, so It helps in having our business logic at a separate location that you can reuse it anytime.
Have look at below snippet,
Here I have created new Class that will override accept class method from Consumer Class, where you can add additional functionility, More than Iteration..!!!!!!
class MyConsumer implements Consumer<Integer>{
@Override
public void accept(Integer o) {
System.out.println("Here you can also add your business logic that will work with Iteration and you can reuse it."+o);
}
}
public class ForEachConsumer {
public static void main(String[] args) {
// Creating simple ArrayList.
ArrayList<Integer> aList = new ArrayList<>();
for(int i=1;i<=10;i++) aList.add(i);
//Calling forEach with customized Iterator.
MyConsumer consumer = new MyConsumer();
aList.forEach(consumer);
// Using Lambda Expression for Consumer. (Functional Interface)
Consumer<Integer> lambda = (Integer o) ->{
System.out.println("Using Lambda Expression to iterate and do something else(BI).. "+o);
};
aList.forEach(lambda);
// Using Anonymous Inner Class.
aList.forEach(new Consumer<Integer>(){
@Override
public void accept(Integer o) {
System.out.println("Calling with Anonymous Inner Class "+o);
}
});
}
}
If $arrayofStringsNotInterestedIn is an [array] you should use -notcontains:
Get-Content $FileName | foreach-object { `
if ($arrayofStringsNotInterestedIn -notcontains $_) { $) }
or better (IMO)
Get-Content $FileName | where { $arrayofStringsNotInterestedIn -notcontains $_}
How about this (improved by Jake's suggestion):
:exe "!mv % newfilename" | e newfilename
paulsm4's answer is the correct one. If in onBackPressed()
you just return, it will disable the back button. However, I think a better approach given your use case is to flip the activity logic, i.e. make your home activity the main one, check if the user is signed in there, if not, start the sign in activity. The reason is that if you override the back button in your main activity, most users will be confused when they press back and your app does nothing.
To get both functions working for a clickable image that will respond to both short and long clicks, I tried the following that seems to work perfectly:
image = (ImageView) findViewById(R.id.imageViewCompass);
image.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
shortclick();
}
});
image.setOnLongClickListener(new View.OnLongClickListener() {
public boolean onLongClick(View v) {
longclick();
return true;
}
});
//Then the functions that are called:
public void shortclick()
{
Toast.makeText(this, "Why did you do that? That hurts!!!", Toast.LENGTH_LONG).show();
}
public void longclick()
{
Toast.makeText(this, "Why did you do that? That REALLY hurts!!!", Toast.LENGTH_LONG).show();
}
It seems that the easy way of declaring the item in XML as clickable and then defining a function to call on the click only applies to short clicks - you must have a listener to differentiate between short and long clicks.
i.ToString("0000");
Don't do this, but this is how you would do it:
$(".overdue").each(function() {
alert("Your book is overdue");
});
The reason I say "don't do it" is because nothing is more annoying to users, in my opinion, than repeated pop-ups that cannot be stopped. Instead, just use the length
property and let them know that "You have X books overdue".
Try this using HTML like here:
var myDate = window.document.getElementById("startdate").value;
I was getting this error. I'm using python 3 in a virtual environment found this in my apache logs

It worked after that
If above solutions not work just one time comment the getter and setter methods of entity class and do not set the value of id.(Primary key) Then this will work.
Well, after researching and fighting with the problem for hours, I found out that there are two ways to accomplish this, depending on the structure of your table and if you have foreign keys restrictions activated to maintain integrity. I'd like to share this in a clean format to save some time to the people that may be in my situation.
In other words, you don't have foreign key, or if you have them, your SQLite engine is configured so that there no are integrity exceptions. The way to go is INSERT OR REPLACE. If you are trying to insert/update a player whose ID already exists, the SQLite engine will delete that row and insert the data you are providing. Now the question comes: what to do to keep the old ID associated?
Let's say we want to UPSERT with the data user_name='steven' and age=32.
Look at this code:
INSERT INTO players (id, name, age)
VALUES (
coalesce((select id from players where user_name='steven'),
(select max(id) from drawings) + 1),
32)
The trick is in coalesce. It returns the id of the user 'steven' if any, and otherwise, it returns a new fresh id.
After monkeying around with the previous solution, I realized that in my case that could end up destroying data, since this ID works as a foreign key for other table. Besides, I created the table with the clause ON DELETE CASCADE, which would mean that it'd delete data silently. Dangerous.
So, I first thought of a IF clause, but SQLite only has CASE. And this CASE can't be used (or at least I did not manage it) to perform one UPDATE query if EXISTS(select id from players where user_name='steven'), and INSERT if it didn't. No go.
And then, finally I used the brute force, with success. The logic is, for each UPSERT that you want to perform, first execute a INSERT OR IGNORE to make sure there is a row with our user, and then execute an UPDATE query with exactly the same data you tried to insert.
Same data as before: user_name='steven' and age=32.
-- make sure it exists
INSERT OR IGNORE INTO players (user_name, age) VALUES ('steven', 32);
-- make sure it has the right data
UPDATE players SET user_name='steven', age=32 WHERE user_name='steven';
And that's all!
As Andy has commented, trying to insert first and then update may lead to firing triggers more often than expected. This is not in my opinion a data safety issue, but it is true that firing unnecessary events makes little sense. Therefore, a improved solution would be:
-- Try to update any existing row
UPDATE players SET age=32 WHERE user_name='steven';
-- Make sure it exists
INSERT OR IGNORE INTO players (user_name, age) VALUES ('steven', 32);
There might be a third party package causing this. In our case it was react-dazzle. We have similar settings to that of @steine (see this answer above).
In order to find the problematic package I ran the webpack build locally with production mode and thus was able to find the problematic package in the stack trace. So for us this provided the solution and I was able to keep the uglification.
Enable Multidex through build.gradle
of your app module
multiDexEnabled true
Same as below -
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.xx.xxx"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
multiDexEnabled true //Add this
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
Then follow below steps -
Build
menu -> press the Clean Project
button.Rebuild Project
button from the Build
menu.File -> Invalidate cashes / Restart
compile

UPDATE: TypeScript 3.4
You can simply use as const
:
const AwesomeType = {
Foo: "foo",
Bar: "bar"
} as const;
TypeScript 2.1
This can also be done this way. Hope it help somebody.
const AwesomeType = {
Foo: "foo" as "foo",
Bar: "bar" as "bar"
};
type AwesomeType = (typeof AwesomeType)[keyof typeof AwesomeType];
console.log(AwesomeType.Bar); // returns bar
console.log(AwesomeType.Foo); // returns foo
function doSth(awesometype: AwesomeType) {
console.log(awesometype);
}
doSth("foo") // return foo
doSth("bar") // returns bar
doSth(AwesomeType.Bar) // returns bar
doSth(AwesomeType.Foo) // returns foo
doSth('error') // does not compile
try:
s.remove("")
except ValueError:
print "new_tag_list has no empty string"
Note that this will only remove one instance of the empty string from your list (as your code would have, too). Can your list contain more than one?
I found the answer, For those who are looking for the same thing here is how I did it. You should not consider uploading images to the database instead you can store the name of the uploaded file in your database and then retrieve the file name and use it where ever you want to display the image.
HTML CODE
<input type="file" name="imageUpload" id="imageUpload">
PHP CODE
if(isset($_POST['submit'])) {
//Process the image that is uploaded by the user
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["imageUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
if (move_uploaded_file($_FILES["imageUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["imageUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
$image=basename( $_FILES["imageUpload"]["name"],".jpg"); // used to store the filename in a variable
//storind the data in your database
$query= "INSERT INTO items VALUES ('$id','$title','$description','$price','$value','$contact','$image')";
mysql_query($query);
require('heading.php');
echo "Your add has been submited, you will be redirected to your account page in 3 seconds....";
header( "Refresh:3; url=account.php", true, 303);
}
CODE TO DISPLAY THE IMAGE
while($row = mysql_fetch_row($result)) {
echo "<tr>";
echo "<td><img src='uploads/$row[6].jpg' height='150px' width='300px'></td>";
echo "</tr>\n";
}
Because that syntax simply isn't defined? Besides, x < y
evaluates as a bool, so what does bool < int
mean? It isn't really an overhead; besides, you could write a utility method if you really want - isBetween(10,x,20)
- I wouldn't myself, but hey...
The problem in your code is that it's creating lots of heavy String
objects, copying their contents and performing operations on them. Instead, you should use StringBuilder
to avoid creating new String
objects on each append and to avoid copying the char arrays. The implementation for your case would be something like this:
BufferedReader r = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder total = new StringBuilder();
for (String line; (line = r.readLine()) != null; ) {
total.append(line).append('\n');
}
You can now use total
without converting it to String
, but if you need the result as a String
, simply add:
String result = total.toString();
I'll try to explain it better...
a += b
(or a = a + b
), where a
and b
are Strings, copies the contents of both a
and b
to a new object (note that you are also copying a
, which contains the accumulated String
), and you are doing those copies on each iteration.a.append(b)
, where a
is a StringBuilder
, directly appends b
contents to a
, so you don't copy the accumulated string at each iteration.The proper way to do with would be to use the v-el
directive to give it a reference. Then you can do this.$$[reference]
.
In Vue 2 refs are used for both elements and components: http://vuejs.org/guide/migration.html#v-el-and-v-ref-replaced
You simply need to enclose your SELECT
statements in parentheses to indicate that they are subqueries:
SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);
Alternatively, you can use MySQL's SELECT ... INTO
syntax. One advantage of this approach is that both cityLat
and cityLng
can be assigned from a single table-access:
SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;
However, the entire procedure can be replaced with a single self-joined SELECT
statement:
SELECT b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM cities AS a, cities AS b
WHERE a.id = cityID
ORDER BY dist
LIMIT 10;
There are several options for removing one or more columns with dplyr::select()
and some helper functions. The helper functions can be useful because some do not require naming all the specific columns to be dropped. Note that to drop columns using select()
you need to use a leading -
to negate the column names.
Using the dplyr::starwars
sample data for some variety in column names:
library(dplyr)
starwars %>%
select(-height) %>% # a specific column name
select(-one_of('mass', 'films')) %>% # any columns named in one_of()
select(-(name:hair_color)) %>% # the range of columns from 'name' to 'hair_color'
select(-contains('color')) %>% # any column name that contains 'color'
select(-starts_with('bi')) %>% # any column name that starts with 'bi'
select(-ends_with('er')) %>% # any column name that ends with 'er'
select(-matches('^v.+s$')) %>% # any column name matching the regex pattern
select_if(~!is.list(.)) %>% # not by column name but by data type
head(2)
# A tibble: 2 x 2
homeworld species
<chr> <chr>
1 Tatooine Human
2 Tatooine Droid
You can also drop by column number:
starwars %>%
select(-2, -(4:10)) # column 2 and columns 4 through 10
If the image is part of the layout it might be "View.VISIBLE" but that doesn't mean it's within the confines of the visible screen. If that's what you're after; this will work:
Rect scrollBounds = new Rect();
scrollView.getHitRect(scrollBounds);
if (imageView.getLocalVisibleRect(scrollBounds)) {
// imageView is within the visible window
} else {
// imageView is not within the visible window
}
By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.
In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.
The client code must set the withCredentials
property on the XMLHttpRequest
to true
in order to give permission.
However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials
header. Responding with this header to true
means that the server allows cookies (or other user credentials) to be included on cross-origin requests.
You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.
Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

document.add(new Paragraph(""))
It is ineffective above,must add a blank string, like this:
document.add(new Paragraph(" "));
My usual methodology for choosing is something like:
Here's my lazy approach:
if (Array.prototype.array_ === undefined) {
Array.prototype.array_ = true;
}
// ...
var test = [],
wat = {};
console.log(test.array_ === true); // true
console.log(wat.array_ === true); // false
I know it's sacrilege to "mess with" the prototype, but it appears to perform significantly better than the recommended toString
method.
Note: A pitfall of this approach is that it wont work across iframe
boundaries, but for my use case this is not an issue.
Using lodash library it is simple as this
_.remove(myArray , { field: 'money' });
Extending Alex's answer slightly:
class User:
def __init__(self):
self.data = [1,2,3]
self.other_data = [4,5,6]
def doSomething(self, source):
dataSource = getattr(self,source)
return dataSource
A = User()
print A.doSomething("data")
print A.doSomething("other_data")
will yield:
[1, 2, 3] [4, 5, 6]
However, personally I don't think that's great style - getattr
will let you access any attribute of the instance, including things like the doSomething
method itself, or even the __dict__
of the instance. I would suggest that instead you implement a dictionary of data sources, like so:
class User:
def __init__(self):
self.data_sources = {
"data": [1,2,3],
"other_data":[4,5,6],
}
def doSomething(self, source):
dataSource = self.data_sources[source]
return dataSource
A = User()
print A.doSomething("data")
print A.doSomething("other_data")
again yielding:
[1, 2, 3] [4, 5, 6]

In case you have binary data in a string (obtained from nodejs
+ readFile(..., 'binary')
, or cypress
+ cy.fixture(..., 'binary')
, etc), you can't use TextEncoder
. It supports only utf8
. Bytes with values >= 128
are each turned into 2 bytes.

If you always want to the same transition animation for the activity
@Override

The best way for me was using vector with categories in order I need as limits
parameter to scale_x_discrete
. I think it is pretty simple and straightforward solution.
ggplot(mtcars, aes(factor(cyl))) +
geom_bar() +
scale_x_discrete(limits=c(8,4,6))
Hy, In my case this error appeared because the Application pool of the webservice had the wrong 32/64 bit setting. So this error needed the following fix: you go to the IIS, select the site of the webservice , go to Advanced setting and get the application pool. Then go to Application pools, select it, go to "Advanced settings..." , select the "Enable 32 bit applications" and make it Enable or Disable, according to the 32/64 bit type of your webservice. If the setting is True, it means that it only allows 32 bit applications, so for 64 bit apps you have to make it "Disable" (default).
Maybe try this? It seems the problem is solved after remove all the handlers in my case.
for handler in logging.root.handlers[:]:
logging.root.removeHandler(handler)
logging.basicConfig(filename='output.log', level=logging.INFO)
Suppose you are executing a java program with nohup you can get java process id by
`ps aux | grep java`
output
xxxxx 9643 0.0 0.0 14232 968 pts/2
then you can kill the process by typing
sudo kill 9643
or lets say that you need to kill all the java processes then just use
sudo killall java
this command kills all the java processes. you can use this with process. just give the process name at the end of the command
sudo killall {processName}
Go back from classpath 'com.android.tools.build:gradle:3.3.0-alpha13' to classpath 'com.android.tools.build:gradle:3.2.0'
this worked for me
adb kill-server
to kill existing adb session adb start-server
to start a new adb sessionIf all above don't solve your problem, you may try delete environment variable named "ANDROID_SDK_HOME
".
It really solved my problem. Hope it Help you!
The only way I can think of doing this is by creating a method that gives you the property using Object.keys();
.
var obj = {
dog: "woof",
cat: "meow",
key: function(n) {
return this[Object.keys(this)[n]];
}
};
obj.key(1); // "meow"
Demo: http://jsfiddle.net/UmkVn/
It would be possible to extend this to all objects using Object.prototype;
but that isn't usually recommended.
Instead, use a function helper:
var object = {
key: function(n) {
return this[ Object.keys(this)[n] ];
}
};
function key(obj, idx) {
return object.key.call(obj, idx);
}
key({ a: 6 }, 0); // 6
In Laravel 3, call path('storage')
.
In Laravel 4, use the storage_path()
helper function.
Being a middle tier developer I like
System.ComponentModel.EditorBrowsableAttribute
Allows me to hide properties so that the UI developer is not overwhelmed with properties that they don't need to see.
System.ComponentModel.BindableAttribute
Some things don't need to be databound. Again, lessens the work the UI developers need to do.
I also like the DefaultValue
that Lawrence Johnston mentioned.
System.ComponentModel.BrowsableAttribute
and the Flags
are used regularly.
I use
System.STAThreadAttribute
System.ThreadStaticAttribute
when needed.
By the way. I these are just as valuable for all the .Net framework developers.
Your query is nearly correct. The T-SQL for this is:
UPDATE Table1
SET Field1 = Table2.Field1,
Field2 = Table2.Field2,
other columns...
FROM Table2
WHERE Table1.ID = Table2.ID
Recently, I have seen this problem too. Below, you have my solution:
Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):
ssh -T [email protected]
Upon receiving a successful response, I could fetch/push to the repo with ssh.
I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.
You can try this:
do {
var op = prompt("please input operatot \n you most select one of * - / * ")
} while (typeof op == "object" || op == "");
// execute block of code when click on cancle or ok whthout input
GNU coreutils has it in lib/base64. It's a little bloated but deals with stuff like EBCDIC. You can also play around on your own, e.g.,
char base64_digit (n) unsigned n; {
if (n < 10) return n - '0';
else if (n < 10 + 26) return n - 'a';
else if (n < 10 + 26 + 26) return n - 'A';
else assert(0);
return 0;
}
unsigned char base64_decode_digit(char c) {
switch (c) {
case '=' : return 62;
case '.' : return 63;
default :
if (isdigit(c)) return c - '0';
else if (islower(c)) return c - 'a' + 10;
else if (isupper(c)) return c - 'A' + 10 + 26;
else assert(0);
}
return 0xff;
}
unsigned base64_decode(char *s) {
char *p;
unsigned n = 0;
for (p = s; *p; p++)
n = 64 * n + base64_decode_digit(*p);
return n;
}
Know ye all persons by these presents that you should not confuse "playing around on your own" with "implementing a standard." Yeesh.
From the shell if you want to show all results you could do db.collection.find().toArray()

This can be done fairly easily with SyntaxHighlighter. I have step-by-step instructions for setting up SyntaxHighlighter in Blogger on my blog. SyntaxHighlighter is very easy to use. It lets you post snippets in raw form and then wrap them in pre
blocks like:
<pre name="code" class="brush: erlang"><![CDATA[
-module(trim).
-export([string_strip_right/1, reverse_tl_reverse/1, bench/0]).
bench() -> [nbench(N) || N <- [1,1000,1000000]].
nbench(N) -> {N, bench(["a" || _ <- lists:seq(1,N)])}.
bench(String) ->
{{string_strip_right,
lists:sum([
element(1, timer:tc(trim, string_strip_right, [String]))
|| _ <- lists:seq(1,1000)])},
{reverse_tl_reverse,
lists:sum([
element(1, timer:tc(trim, reverse_tl_reverse, [String]))
|| _ <- lists:seq(1,1000)])}}.
string_strip_right(String) -> string:strip(String, right, $\n).
reverse_tl_reverse(String) ->
lists:reverse(tl(lists:reverse(String))).
]]></pre>
Just change the brush name to "python" or "java" or "javascript" and paste in the code of your choice. The CDATA tagging let's you put pretty much any code in there without worrying about entity escaping or other typical annoyances of code blogging.
Tell PDO your charset

DON'T DO THIS IN PRODUCTION
The answer given by @ravi-luthra technically works but it has some issues!
In my case, I was just trying to recover disk space. The lib/docker/overlay
folder was taking 30GB of space and I only run a few containers regularly. Looks like docker has some issue with data leakage and some of the temporary data are not cleared when the container stops.
So I went ahead and deleted all the contents of lib/docker/overlay
folder. After that, My docker instance became un-useable. When I tried to run or build any container, It gave me this error:
failed to create rwlayer: symlink ../04578d9f8e428b693174c6eb9a80111c907724cc22129761ce14a4c8cb4f1d7c/diff /var/lib/docker/overlay2/l/C3F33OLORAASNIYB3ZDATH2HJ7: no such file or directory
Then with some trial and error, I solved this issue by running
(WARNING: This will delete all your data inside docker volumes)
docker system prune --volumes -a
So It is not recommended to do such dirty clean ups unless you completely understand how the system works.
In my case I had no SDK selected for my project(not sure why). Simply went to Project Structure dialog (alt+ctrl+shift+s
or button 1 on the screen) and then to project-> Project SDK's was selected <no SDK>
. Just changed it to the latest
You can select the video player and then set its volume:
var mp = iframe.getElementById('movie_player');
mp.setVolume(0);
from documentation http://www.w3.org/TR/XMLHttpRequest/#the-status-attribute means a request was cancelled before going anywhere
For iTunes 12.9.5.5 and above you can install the apps by Copying
the IPA file and Paste
it (Cmd+V or Edit -> Paste in iTunes) in any categories as Music/Films/TV Programmes etc. The app will be installed automatically on your iPhone screen.
Tested on 29 Nov 2019.
When you logout from your app, at that time you have to use a below line of code on your logout button click method.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
and this works perfectly in my app.
You can easily add multiple classes to divs... So:
<div class="myclass myclass-one"></div>
<div class="myclass myclass-two"></div>
<div class="myclass myclass-three"></div>
Then in the CSS call to the share class to apply the same styles:
.myclass {...}
And you can still use your other classes like this:
.myclass-three {...}
Or if you want to be more specific in the CSS like this:
.myclass.myclass-three {...}

If you want to do a POST from the same domain, you can always insert a form into the DOM using Developer tools and submit that:
Get rid from your <Button>
wrap div using display:block
and float:left
in both <Button>

and specifying their width
with a position:relative
to your Section
. This approach has the advantage of not needing another div
only to position your <Button>

Here is my one liner. Here 'c' is the name of the column
df.select('c').withColumn('isNull_c',F.col('c').isNull()).where('isNull_c = True').count()
function CaracteresAleatorios( $Tamanno, $Opciones) {
$Opciones = empty($Opciones) ? array(0, 1, 2) : $Opciones;
$Tamanno = empty($Tamanno) ? 16 : $Tamanno;
$Caracteres=array("0123456789","abcdefghijklmnopqrstuvwxyz","ABCDEFGHIJKLMNOPQRSTUVWXYZ");
$Caracteres= implode("",array_intersect_key($Caracteres, array_flip($Opciones)));
$CantidadCaracteres=strlen($Caracteres)-1;
$CaracteresAleatorios='';
for ($k = 0; $k < $Tamanno; $k++) {
$CaracteresAleatorios.=$Caracteres[rand(0, $CantidadCaracteres)];
}
return $CaracteresAleatorios;
}
$(document).ready(function () {
$('.dates li a').click(function (e) {
$('.dates li a').removeClass('active');
var $parent = $(this);
if (!$parent.hasClass('active')) {
$parent.addClass('active');
}
e.preventDefault();
});
});
If you want to retrieve the key's value if it exists, you can also use
try:
value = a[key]
except KeyError:
# Key is not present
pass
If you want to retrieve a default value when the key does not exist, use
value = a.get(key, default_value)
.
If you want to set the default value at the same time in case the key does not exist, use
value = a.setdefault(key, default_value)
.
If you need a quick fix, simply add this before the line of your import:
// @ts-ignore
Use REN
Command
Ren
is for rename
ren ( where the file is located ) ( the new name )
example
ren C:\Users\&username%\Desktop\aaa.txt bbb.txt
it will change aaa.txt to bbb.txt
Your code will be :
ren (file located)AAA_a001.jpg a001.AAA.jpg
ren (file located)BBB_a002.jpg a002.BBB.jpg
ren (file located)CCC_a003.jpg a003.CCC.jpg
and so on
IT WILL NOT WORK IF THERE IS SPACES!
Hope it helps :D
I just solved this error happening in my tests.
Just make sure your test class has all dependencies in the attributes of the class being tested annotated with @MockBean
so SpringBoot test context can wire your classes correctly.
Only if you are testing controller: you need also class annotations to load the Controller context propertly.
Check it out:
@DisplayName("UserController Adapter Test")
@WebMvcTest(UserController.class)
@AutoConfigureMockMvc(addFilters = false)
@Import(TestConfig.class)
public class UserControllerTest {
@Autowired
private MockMvc mockMvc;
@Autowired
private ObjectMapper objectMapper;
@MockBean
private CreateUserCommand createUserCommand;
@MockBean
private GetUserListQuery getUserListQuery;
@MockBean
private GetUserQuery getUserQuery;
You should declare the variable in a header file:
extern int x;
and then define it in one C file:
int x;
In C, the difference between a definition and a declaration is that the definition reserves space for the variable, whereas the declaration merely introduces the variable into the symbol table (and will cause the linker to go looking for it when it comes to link time).
you can take care of the first 3 items with slicing and head:
df[df.A>=4].head(1)
df[(df.A>=4)&(df.B>=3)].head(1)
df[(df.A>=4)&((df.B>=3) * (df.C>=2))].head(1)
The condition in case nothing comes back you can handle with a try or an if...
try:
output = df[df.A>=6].head(1)
assert len(output) == 1
except:
output = df.sort_values('A',ascending=False).head(1)
In my case it happened when calling a function by passing a parameter of a Core Data managed object's property. At the time of calling the object was no longer existed, and that caused this error.
I have solved the issue by checking if the managed object exists or not before calling the function.
A very important note on the 16, 32 and 64 types:
if you run this query... Array.IndexOf(new Int16[]{1,2,3}, 1)
you are suppose to get zero(0) because you are asking... is 1 within the array of 1, 2 or 3. if you get -1 as answer, it means 1 is not within the array of 1, 2 or 3.
Well check out what I found: All the following should give you 0 and not -1 (I've tested this in all framework versions 2.0, 3.0, 3.5, 4.0)
C#:
Array.IndexOf(new Int16[]{1,2,3}, 1) = -1 (not correct)
Array.IndexOf(new Int32[]{1,2,3}, 1) = 0 (correct)
Array.IndexOf(new Int64[]{1,2,3}, 1) = 0 (correct)
VB.NET:
Array.IndexOf(new Int16(){1,2,3}, 1) = -1 (not correct)
Array.IndexOf(new Int32(){1,2,3}, 1) = 0 (correct)
Array.IndexOf(new Int64(){1,2,3}, 1) = -1 (not correct)
So my point is, for Array.IndexOf comparisons, only trust Int32!
// this is how I always do it
for (i = n; --i >= 0;){
...
}
The solution you are really looking for is web sockets. However, the chromium project has developed some new technologies that are direct TCP connections TCP chromium
I've solved this problem by using the search function on Docker's website where '*' is a valid search that returns 200k repositories and then I crawled each invididual page. HTML parsing allows me to extract all the image names on each page.
In the IIS Manager, under Authentication, disable: 1) Anonymous Authentication 2) Forms Authentication
Then add the following to your controller, to handle testing versus server deployment:
string sUserName = null;
string url = Request.Url.ToString();
if (url.Contains("localhost"))
sUserName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
else
sUserName = User.Identity.Name;
Returns true if comes 'y', '1', 'true', 'on'or whatever you add in similar way
boolean getValue(String value) {
return ("Y".equals(value.toUpperCase())
|| "1".equals(value.toUpperCase())
|| "TRUE".equals(value.toUpperCase())
|| "ON".equals(value.toUpperCase())
);
}
In global scope there is no semantic difference.
But you really should avoid a=0
since your setting a value to an undeclared variable.
Also use closures to avoid editing global scope at all
(function() {
// do stuff locally
// Hoist something to global scope
window.someGlobal = someLocal
}());
Always use closures and always hoist to global scope when its absolutely neccesary. You should be using asynchronous event handling for most of your communication anyway.
As @AvianMoncellor mentioned there is an IE bug with var a = foo
only declaring a global for file scope. This is an issue with IE's notorious broken interpreter. This bug does sound familiar so it's probably true.
So stick to window.globalName = someLocalpointer
You can read up elsewhere on substitution variables; they're quite handy in SQL Developer. But I have fits trying to use bind variables in SQL Developer. This is what I do:
SET SERVEROUTPUT ON
declare
v_testnum number;
v_teststring varchar2(1000);
begin
v_testnum := 2;
DBMS_OUTPUT.put_line('v_testnum is now ' || v_testnum);
SELECT 36,'hello world'
INTO v_testnum, v_teststring
from dual;
DBMS_OUTPUT.put_line('v_testnum is now ' || v_testnum);
DBMS_OUTPUT.put_line('v_teststring is ' || v_teststring);
end;
SET SERVEROUTPUT ON
makes it so text can be printed to the script output console.
I believe what we're doing here is officially called PL/SQL. We have left the pure SQL land and are using a different engine in Oracle. You see the SELECT
above? In PL/SQL you always have to SELECT ... INTO
either variable or a refcursor. You can't just SELECT
and return a result set in PL/SQL.
Make sure your .NET version 4.5 or greater
I would use it like this, its way shorter and it won't give any problems
dynamic result = null;
if (methodInfo != null)
{
ParameterInfo[] parameters = methodInfo.GetParameters();
object classInstance = Activator.CreateInstance(type, null);
result = methodInfo.Invoke(classInstance, parameters.Length == 0 ? null : parametersArray);
}
As of 30Jul, 2018 to fix the above issue, one can configure the java version used within maven to any up to JDK/11 and make use of the maven-compiler-plugin:3.8.0
to specify a release of either 9,10,11 without any explicit dependencies.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<release>11</release> <!--or <release>10</release>-->
</configuration>
</plugin>
Note:- The default value for source/target has been lifted from 1.5 to 1.6 with this version. -- release notes.
Edit [30.12.2018]
In fact, you can make use of the same version of maven-compiler-plugin
while compiling the code against JDK/12 as well.
More details and a sample configuration in how to Compile and execute a JDK preview feature with Maven.
UseParNewGC A parallel version of the young generation copying collector is used with the concurrent collector (i.e. if -XX:+ UseConcMarkSweepGC is used on the command line then the flag UseParNewGC is also set to true if it is not otherwise explicitly set on the command line).

In my project I'm doing this and it works fine:
[Link](https://example.org/ "title" target="_blank")
But not all parsers let you do that.
C# has tuples as of version 4.0.
The same error occurs also when doing SELECT DISTINCT ..., <CLOB_column>, ...
.
If this CLOB column contains values shorter than limit for VARCHAR2 in all the applicable rows you may use to_char(<CLOB_column>)
or concatenate results of multiple calls to DBMS_LOB.SUBSTR(<CLOB_column>, ...)
.
$(function(){
$("input[type='submit']").click(function () {

thant's it.
The following CSS based solution works for me:

white-space: nowrap;
overflow: scroll;
overflow-y: hidden;
overflow-x: scroll;
overflow: -moz-scrollbars-horizontal;

<body>
<form>
<textarea>This is a long line of text for testing purposes...</textarea>

Why don't you use a for loop instead of using foreach. In this scenario, there is no way you can get the index of the current iteration of the foreach loop.
The name of the file can be added to the string[] in this way,
private string[] ColeccionDeCortes(string Path)
{
DirectoryInfo X = new DirectoryInfo(Path);
FileInfo[] listaDeArchivos = X.GetFiles();

Good question, I was just looking for alternatives to JFreeChart myself the other day. JFreeChart is excellent and very comprehensive, I've used it on several projects. My recent problem was that it meant adding 1.6mb of libraries to a 50kb applet, so I was looking for something smaller.
The JFreeChart FAQ itself lists alternatives. Compared to JFreeChart, most of them are pretty basic, and some pretty ugly. The most promising seem to be the Java Chart Construction Kit and OpenChart2.
I also found EasyCharts, which is a commercial product but seemingly free to use in some circumstances.
In the end, I went back to the tried and trusted JFreeChart and used Proguard to butcher it into a more manageable size.
I suggest that you take another look at JFreeChart. The user guide is only available to buy, but the demo shows what is possible and it's pretty easy to work out how from the API documentation. Basically you start with the ChartFactory static methods and plug the resultant JFreeChart object into a ChartPanel to display it. If you get stuck, I'm sure you'll get some quick answers to your problems on StackOverflow.
Gradient descent algorithm uses the constant learning rate which you can provide in during the initialization. You can pass various learning rates in a way showed by Mrry.
But instead of it you can also use more advanced optimizers which have faster convergence rate and adapts to the situation.
Here is a brief explanation based on my understanding:
Adam or adaptive momentum is an algorithm similar to AdaDelta. But in addition to storing learning rates for each of the parameters it also stores momentum changes for each of them separately
Daniel is right: http://ideone.com/kgbo1C#view_edit_box
Change
test=substring(i,j,*s);
to
test=substring(i,j,s);
Also, you need to forward declare substring:
char *substring(int i,int j,char *ch);

As mentioned by theoobe, some browsers do not close the websockets automatically. Don't try to handle any "close browser window" events client-side. There is currently no reliable way to do it, if you consider support of major desktop AND mobile browsers (e.g. onbeforeunload
will not work in Mobile Safari). I had good experience with handling this problem server-side. E.g. if you use Java EE, take a look at javax.websocket.Endpoint, depending on the browser either the OnClose
method or the OnError
method will be called if you close/reload the browser window.
SELECT id FROM a -- returns 1,4,2,3
UNION
SELECT id FROM b -- returns 2,1
order by 2,1
As another cheap alternative on somewhat static canvas, using an overlaying img element with a usemap definition is quick and dirty. Works especially well on polygon based canvas elements like a pie chart.
Apache Camel is a Java framework for Enterprise integration. Eg:- if you are building a web application which interacts with many vendor API's we can use the camel as the External integration tool. We can do more with it based on the use case. Camel in Action from Manning publications is a great book for learning Camel. The integrations can be defined as below.
Java DSL
from("jetty://0.0.0.0:8080/searchProduct").routeId("searchProduct.products").threads()
.log(LoggingLevel.INFO, "searchProducts request Received with body: ${body}")
.bean(Processor.class, "createSearchProductsRequest").removeHeaders("CamelHttp*")
.setHeader(Exchange.HTTP_METHOD, constant(org.apache.camel.component.http4.HttpMethods.POST))
.to("http4://" + preLiveBaseAPI + searchProductsUrl + "?apiKey=" + ApiKey
+ "&bridgeEndpoint=true")
.bean(Processor.class, "buildResponse").log(LoggingLevel.INFO, "Search products finished");
This is to just create a REST API endpoint which in turn calls an external API and sends the request back
Spring DSL
<route id="GROUPS-SHOW">
<from uri="jetty://0.0.0.0:8080/showGroups" />
<log loggingLevel="INFO" message="Reqeust receviced service to fetch groups -> ${body}" />
<to uri="direct:auditLog" />
<process ref="TestProcessor" />
</route>
Coming to your questions
Hope it helps
Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.
OpenSessionInViewFilter
calls the openSession
method of the underlying SessionFactory
and obtains a new Session
.Session
is bound to the TransactionSynchronizationManager
.OpenSessionInViewFilter
calls the doFilter
of the javax.servlet.FilterChain
object reference and the request is further processedDispatcherServlet
is called, and it routes the HTTP request to the underlying PostController
.PostController
calls the PostService
to get a list of Post
entities.PostService
opens a new transaction, and the HibernateTransactionManager
reuses the same Session
that was opened by the OpenSessionInViewFilter
.PostDAO
fetches the list of Post
entities without initializing any lazy association.PostService
commits the underlying transaction, but the Session
is not closed because it was opened externally.DispatcherServlet
starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.OpenSessionInViewFilter
can close the Session
, and the underlying database connection is released as well.At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.
The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection
as read-only which would allow the database server to avoid writing to the transaction log.
There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.
The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize
for fetching associations in batches, and FetchMode.SUBSELECT
to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.
Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.
Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.
So, make sure that in the application.properties
configuration file, you have the following entry:
spring.jpa.open-in-view=false
This will disable OSIV so that you can handle the LazyInitializationException
the right way.
Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.
As a general point when using a search engine to search for SQL codes make sure you put the sqlcode e.g. -302 in quote marks - like "-302" otherwise the search engine will exclude all search results including the text 302, since the - sign is used to exclude results.
If this really is a QA issue and you can't change the code. Setup a new server instance on the machine and setup the language as "British English"
For all files (default setting for opened file): Settings/Preferences | Editor | General | Use soft wraps in editor
For currently opened file in editor: Menu | View | Active Editor | Use Soft Wraps
In latest IDE versions you can also access this option via context menu for the editor gutter area (the area with line numbers on the left side of the editor).
Search Everywhere
(Shift 2x times) or Help | Find Action...
( Ctrl + Shift+ A on Windows using Default keymap) can also be used to quickly change this option (instead of going into Settings/Preferences).
Tried list[:][0]
to show all first member of each list inside list is not working. Result is unknowingly will same as list[0][:]
So i use list comprehension like this:
[i[0] for i in list]
which return first element value for each list inside list.
Try this: Set your image crop dimensions and use this line in your CSS:
object-fit: cover;
No, I don't know one.
If you want to retain the original directory for some reason (ACLs, &c.), and instead really want to empty it, then you can do the following:
del /q destination\*
for /d %x in (destination\*) do @rd /s /q "%x"
This first removes all files from the directory, and then recursively removes all nested directories, but overall keeping the top-level directory as it is (except for its contents).
Note that within a batch file you need to double the %
within the for
loop:
del /q destination\*
for /d %%x in (destination\*) do @rd /s /q "%%x"
If you assume that 0 is not a valid item in the array then the following code should work:
public static void main( String[] args )
{
int[] theArray = new int[20];
theArray[0] = 1;
theArray[1] = 2;
System.out.println(count(theArray));
}
private static int count(int[] array)
{
int count = 0;
for(int i : array)
{
if(i > 0)
{
count++;
}
}
return count;
}
In my case if you are using UITableView
do not forget to add UITableViewDelegate and UITableViewDataSource next to viewcontroller like this. class MenuController: UIViewController, UITableViewDelegate, UITableViewDataSource
When converting old projects (written in Swift 2.3) to Swift 3 it needs adding these keywords.
Here's another way to process command line args, using R CMD BATCH
. My approach, which builds on an earlier answer here, lets you specify arguments at the command line and, in your R script, give some or all of them default values.
Here's an R file, which I name test.R:
defaults <- list(a=1, b=c(1,1,1)) ## default values of any arguments we might pass
## parse each command arg, loading it into global environment
for (arg in commandArgs(TRUE))
eval(parse(text=arg))
## if any variable named in defaults doesn't exist, then create it
## with value from defaults
for (nm in names(defaults))
assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]))[[1]])
print(a)
print(b)
At the command line, if I type
R CMD BATCH --no-save --no-restore '--args a=2 b=c(2,5,6)' test.R
then within R we'll have a
= 2
and b
= c(2,5,6)
. But I could, say, omit b
, and add in another argument c
:
R CMD BATCH --no-save --no-restore '--args a=2 c="hello"' test.R
Then in R we'll have a
= 2
, b
= c(1,1,1)
(the default), and c
= "hello"
.
Finally, for convenience we can wrap the R code in a function, as long as we're careful about the environment:
## defaults should be either NULL or a named list
parseCommandArgs <- function(defaults=NULL, envir=globalenv()) {
for (arg in commandArgs(TRUE))
eval(parse(text=arg), envir=envir)
for (nm in names(defaults))
assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]), envir=envir)[[1]], pos=envir)
}
## example usage:
parseCommandArgs(list(a=1, b=c(1,1,1)))
this should work, had to try a while too.. :D

This is actually really easy:
overflow:hidden
does not always mean that the element is hidden or non existent in the DOM, it means that the overflowing chars that do not fit in the element are being trimmed. Basically it means that do not show scrollbar even if it should be showed, so in your case the link with text
Plastic Spiral Bind
could possibly be shown as "Plastic Spir..." or similar. So it is possible, that this linkText indeed is non existent.
So you can probably try:
driver.findElement(By.partialLinkText("Plastic ")).click();
or xpath:
//a[contains(@title, \"Plastic Spiral Bind\")]
xxx >& filename
Or do this to see everything on the screen and have it go to your file:
xxx | & tee ./logfile
In addition to the above posts, i'd like to point out that "man ls" will give you a nice manual about the "ls" ( List " command.
Also, using ls -la myFile will list & show all the facts about that file.
You can do this:
if ($('#form_id :checkbox:checked').length > 0){
// one or more checkboxes are checked
}
else{
// no checkboxes are checked
}

I faced similar exception. Check if all columns has header names( from select query in database) with exactly matching property names in model class.
You should try using nohup
and running it in the background:
nohup sleep 3600 &
You can use the StackTrace class to get the name of the current function, (or if you put the code in a function, then step down a level and get the calling function).
See http://msdn.microsoft.com/en-us/library/system.diagnostics.stacktrace(VS.71).aspx
Node.js uses the environmental variable NODE_PATH
to allow for specifying additional directories to include in the module search path. You can use npm
itself to tell you where global modules are stored with the npm root -g
command. So putting those two together, you can make sure global modules are included in your search path with the following command (on Linux-ish)
export NODE_PATH=$(npm root --quiet -g)
You're correct. As others said according to your comments, you probably did not initialize your ArrayList.
My point is different: you claimed that you're checking for duplicates and this is why you call the contains method. Try using HashSet
. It should be more efficient - unless you need to keep the order of URLs for any reason.

Addition to Alex' answer:
$(function() {
$('input[type="submit"]').prop('disabled', true);
$('#check').on('input', function(e) {
if(this.value.length === 6) {
$('input[type="submit"]').prop('disabled', false);
} else {
$('input[type="submit"]').prop('disabled', true);
}
});
});
<input type="text" maxlength="6" id="check" data-minlength="6" /><br />
<input type="submit" value="send" />
But: You should always remember to validate the user input on the server side again. The user could modify the local HTML or disable JavaScript.
simple example:
<div ng-style="isTrue && {'background-color':'green'} || {'background-color': 'blue'}" style="width:200px;height:100px;border:1px solid gray;"></div>
{'background-color':'green'} RETURN true
OR the same result:
<div ng-style="isTrue && {'background-color':'green'}" style="width:200px;height:100px;border:1px solid gray;background-color: blue"></div>
other conditional possibility:
<div ng-style="count === 0 && {'background-color':'green'} || count === 1 && {'background-color':'yellow'}" style="width:200px;height:100px;border:1px solid gray;background-color: blue"></div>
I want to just refresh the div, without refreshing the page ... Is this possible?
Yes, though it isn't going to be obvious that it does anything unless you change the contents of the div.
If you just want the graphical fade-in effect, simply remove the .html(data)
call:
$("#panel").hide().fadeIn('fast');
Here is a demo you can mess around with: http://jsfiddle.net/ZPYUS/
It changes the contents of the div without making an ajax call to the server, and without refreshing the page. The content is hard coded, though. You can't do anything about that fact without contacting the server somehow: ajax, some sort of sub-page request, or some sort of page refresh.
html:
<div id="panel">test data</div>
<input id="changePanel" value="Change Panel" type="button">?
javascript:
$("#changePanel").click(function() {
var data = "foobar";
$("#panel").hide().html(data).fadeIn('fast');
});?
css:
div {
padding: 1em;
background-color: #00c000;
}
input {
padding: .25em 1em;
}?
simple as this
myObj.name = value;
You're missing the actual pipe.
{{ myData | date:'fullDate' }}
Multiple parameters can be separated by a colon (:).
{{ myData | myPipe:'arg1':'arg2':'arg3' }}
Also you can chain pipes, like so:
{{ myData | date:'fullDate' | myPipe:'arg1':'arg2':'arg3' }}
I just want to be sure that the float number will also have 2 decimal places after converting that string.
You can't, because floating point numbers don't have decimal places. They have binary places, which aren't commensurate with decimal places.
If you want decimal places, use a decimal radix.
Just Add reference to System.Web.Extensions and happy to go.
Ensure debug mode is on - either add APP_DEBUG=true
to .env file or set an environment variable
Log files are in storage/logs folder. laravel.log
is the default filename. If there is a permission issue with the log folder, Laravel just halts. So if your endpoint generally works - permissions are not an issue.
In case your calls don't even reach Laravel or aren't caused by code issues - check web server's log files (check your Apache/nginx config files to see the paths).
If you use PHP-FPM, check its log files as well (you can see the path to log file in PHP-FPM pool config).
Another way ..
<img ng-src="{{!video.playing ? 'img/icons/play-rounded-button-outline.svg' : 'img/icons/pause-thin-rounded-button.svg'}}" />
You can use JSON.parse, adding brakets to format Array
const a = "1,2,3,4";
const myArray = JSON.parse(`[${a}]`)
console.log(myArray)
console.info('pos 2 = ', myArray[2])

The best and most effective solution is just adding theme in your main class and add input decoration like these.
theme: ThemeData(
inputDecorationTheme: InputDecorationTheme(
border: OutlineInputBorder(
borderSide: BorderSide(color: Colors.pink)
)
),
)
<table cellpadding="pixels"cellspacing="pixels"></table>
<td align="position"valign="position"></td>
cellpadding
="length in pixels" ~ The cellpadding attribute, used in the <table>
tag, specifies how much blank space to display in between the content of each table cell and its respective border. The value is defined as a length in pixels. Hence, a cellpadding="10"
attribute-value pair will display 10 pixels of blank space on all four sides of the content of each cell in that table.
cellspacing
="length in pixels" ~ The cellspacing attribute, also used in the <table>
tag, defines how much blank space to display in between adjacent table cells and in between table cells and the table border. The value is defined as a length in pixels. Hence, a cellspacing="10"
attribute-value pair will horizontally and vertically separate all adjacent cells in the respective table by a length of 10 pixels. It will also offset all cells from the table's frame on all four sides by a length of 10 pixels.
While you cannot modify a column as such, you may operate on a column and return a new DataFrame reflecting that change. For that you'd first create a UserDefinedFunction
implementing the operation to apply and then selectively apply that function to the targeted column only. In Python:
from pyspark.sql.functions import UserDefinedFunction
from pyspark.sql.types import StringType
name = 'target_column'
udf = UserDefinedFunction(lambda x: 'new_value', StringType())
new_df = old_df.select(*[udf(column).alias(name) if column == name else column for column in old_df.columns])
new_df
now has the same schema as old_df
(assuming that old_df.target_column
was of type StringType
as well) but all values in column target_column
will be new_value
.
from platform import python_version
print(python_version())
This will give you the exact version of python running your script. eg output:
3.6.5

I think you can do this with the hyperref
package, although I've not tried it myself. From the relevant LaTeX Wikibook section:
The
hyperref
package introduces another useful command;\autoref{}
. This command creates a reference with additional text corresponding to the targets type, all of which will be a hyperlink. For example, the command\autoref{sec:intro}
would create a hyperlink to the\label{sec:intro}
command, wherever it is. Assuming that this label is pointing to a section, the hyperlink would contain the text "section 3.4", or similar (capitalization rules will be followed, which makes this very convenient). You can customize the prefixed text by redefining\typeautorefname
to the prefix you want, as in:
\def\subsectionautorefname{section}
A simple solution is to wrap the query into a subselect with the ORDER statement first and applying the GROUP BY later:
SELECT * FROM (
SELECT `timestamp`, `fromEmail`, `subject`
FROM `incomingEmails`
ORDER BY `timestamp` DESC
) AS tmp_table GROUP BY LOWER(`fromEmail`)
This is similar to using the join but looks much nicer.
Using non-aggregate columns in a SELECT with a GROUP BY clause is non-standard. MySQL will generally return the values of the first row it finds and discard the rest. Any ORDER BY clauses will only apply to the returned column value, not to the discarded ones.
IMPORTANT UPDATE Selecting non-aggregate columns used to work in practice but should not be relied upon. Per the MySQL documentation "this is useful primarily when all values in each nonaggregated column not named in the GROUP BY are the same for each group. The server is free to choose any value from each group, so unless they are the same, the values chosen are indeterminate."
As of 5.7.5 ONLY_FULL_GROUP_BY is enabled by default so non-aggregate columns cause query errors (ER_WRONG_FIELD_WITH_GROUP)
As @mikep points out below the solution is to use ANY_VALUE() from 5.7 and above
See http://www.cafewebmaster.com/mysql-order-sort-group https://dev.mysql.com/doc/refman/5.6/en/group-by-handling.html https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html https://dev.mysql.com/doc/refman/5.7/en/miscellaneous-functions.html#function_any-value
You are looking for:
var yourVar = '1324567890abc§$)%';
yourVar = yourVar.replace(/[^a-zA-Z0-9]/g, ' ');
This replaces all non-alphanumeric characters with a space.
The "g" on the end replaces all occurrences.
Instead of specifying a-z (lowercase) and A-Z (uppercase) you can also use the in-case-sensitive option: /[^a-z0-9]/gi
.
Try using the duplicated function in combination with the negation operator "!".
Example:
wdups <- rep(1:5,5)
wodups <- wdups[which(!duplicated(wdups))]
Hope that helps.
The another trick is by setting the parent loop to reach the end and then break the current loop
function foo()
{
for(var k = 0; k < 4; k++){
for(var m = 0; m < 4; m++){
if(m == 2){
k = 5; // Set this then break
break;
}
console.log(m);
}
}
}
If you are using .net core, then during development you can bypass certificate validation by using compiler directives. This way will only validate certificate for release and not for debug:
#if (DEBUG)
client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
new X509ServiceCertificateAuthentication()
{
CertificateValidationMode = X509CertificateValidationMode.None,
RevocationMode = System.Security.Cryptography.X509Certificates.X509RevocationMode.NoCheck
}; #endif
Use a static Random or the numbers tend to repeat in tight/fast loops due to the system clock seeding them.
public static class RandomNumbers
{
private static Random random = new Random();
//=-------------------------------------------------------------------
// double between min and the max number
public static double RandomDouble(int min, int max)
{
return (random.NextDouble() * (max - min)) + min;
}
//=----------------------------------
// double between 0 and the max number
public static double RandomDouble(int max)
{
return (random.NextDouble() * max);
}
//=-------------------------------------------------------------------
// int between the min and the max number
public static int RandomInt(int min, int max)
{
return random.Next(min, max + 1);
}
//=----------------------------------
// int between 0 and the max number
public static int RandomInt(int max)
{
return random.Next(max + 1);
}
//=-------------------------------------------------------------------
}

I read a lot of tutorials that suggested hacks, so I came up with this solution I think is better... It seems to work fine.
@font-face {
font-family: MyFont; src: url('myfont.ttf');
}
@font-face{
font-family: MyFont_IE; src: url('myfont.eot');
}
.my_font{
font-family: MyFont, MyFont_IE, Arial, Helvetica, sans-serif;
}
You can use disabled attribute to disable the textbox.
document.getElementById('color').disabled = true;
This is how I did it for the dataset I was using. It seems convoluted and stupid, but it was the only alternative to learning how to use the VB solution mentioned above.
q
since it wasn't anywhere on my data sheet.q
with nothing. This three step process turned all of the "empty" cells into "blank" cells". I tried merging steps 2 & 3 by simply replacing the blank cell with a blank cell, but that didn't work--I had to replace the blank cell with some kind of actual text, then replace that text with a blank cell.
You can go with @greenAfrican example, if it's possible for you to rewrite your function. But if you don't want to rewrite your function, you can wrap it into anonymous function inside apply, like this:
>>> def fxy(x, y):
... return x * y
>>> df['newcolumn'] = df.apply(lambda x: fxy(x['A'], x['B']), axis=1)
>>> df
A B newcolumn
0 10 20 200
1 20 30 600
2 30 10 300
Here is a method that uses stamper and absolute coordinates showed in the different PDF clients (Adobe, FoxIt and etc. )
public static void AddTextToPdf(string inputPdfPath, string outputPdfPath, string textToAdd, System.Drawing.Point point)
{
//variables
string pathin = inputPdfPath;
string pathout = outputPdfPath;
//create PdfReader object to read from the existing document
using (PdfReader reader = new PdfReader(pathin))
//create PdfStamper object to write to get the pages from reader
using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
{
//select two pages from the original document
reader.SelectPages("1-2");
//gettins the page size in order to substract from the iTextSharp coordinates
var pageSize = reader.GetPageSize(1);
// PdfContentByte from stamper to add content to the pages over the original content
PdfContentByte pbover = stamper.GetOverContent(1);
//add content to the page using ColumnText
Font font = new Font();
font.Size = 45;
//setting up the X and Y coordinates of the document
int x = point.X;
int y = point.Y;
y = (int) (pageSize.Height - y);
ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
}
}
Shows all the stored procedures:
SHOW PROCEDURE STATUS;
Shows all the functions:
SHOW FUNCTION STATUS;
Shows the definition of the specified procedure:
SHOW CREATE PROCEDURE [PROC_NAME];
Shows you all the procedures of the given database:
SHOW PROCEDURE STATUS WHERE Db = '[db_name]';
For my case handling UIDeviceOrientationDidChangeNotification
was not good solution as it is called more frequent and UIDeviceOrientation
is not always equal to UIInterfaceOrientation
because of (FaceDown, FaceUp).
I handle it using UIApplicationDidChangeStatusBarOrientationNotification
:
//To add the notification
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didChangeOrientation:)
//to remove the
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];
...
- (void)didChangeOrientation:(NSNotification *)notification
{
UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
if (UIInterfaceOrientationIsLandscape(orientation)) {
NSLog(@"Landscape");
}
else {
NSLog(@"Portrait");
}
}
Why not use ES6?
var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
const [, ...rest] = myarray;_x000D_
console.log(rest)
_x000D_
In .NET you can use grouping to your advantage like this:
http://regexhero.net/tester/?id=65b32601-2326-4ece-912b-6dcefd883f31
You'll notice that:
(ABC)|(.)
Will grab everything except ABC in the 2nd group. Parenthesis surround each group. So (ABC) is group 1 and (.) is group 2.
So you just grab the 2nd group like this in a replace:
$2
Or in .NET look at the Groups collection inside the Regex class for a little more control.
You should be able to do something similar in most other regex implementations as well.
UPDATE: I found a much faster way to do this here: http://regexhero.net/tester/?id=997ce4a2-878c-41f2-9d28-34e0c5080e03
It still uses grouping (I can't find a way that doesn't use grouping). But this method is over 10X faster than the first.
I was having the same problem, I had a ComboBox followed by a ListBox in a StackPanel and the scroll bar for the ListBox was not showing up. I solved this by putting the two in a DockPanel instead. I set the ComboBox DockPanel.Dock="Top" and let the ListBox fill the remaining space.
It's not a matter of pixels count, it's a matter of actual size (in mm or inches) of characters on the screen, which depends on pixels density. Hence "min-width:" and "max-width:" are useless. A full explanation of this issue is here: what exactly is device pixel ratio?
"@media" queries take into account the pixels count and the device pixel ratio, resulting in a "virtual resolution" which is what you have to actually take into account while designing your page: if your font is 10px fixed-width and the "virtual horizontal resolution" is 300 px, 30 characters will be needed to fill a line.
WordUtils.capitalizeFully(str)
from apache commons-lang has the exact semantics as required.
If your keys are dynamic I would suggest deserializing directly into a DataTable:
class SampleData
{
[JsonProperty(PropertyName = "items")]
public System.Data.DataTable Items { get; set; }
}
public void DerializeTable()
{
const string json = @"{items:["
+ @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
+ @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
+ @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
var table = sampleData.Items;
// write tab delimited table without knowing column names
var line = string.Empty;
foreach (DataColumn column in table.Columns)
line += column.ColumnName + "\t";
Console.WriteLine(line);
foreach (DataRow row in table.Rows)
{
line = string.Empty;
foreach (DataColumn column in table.Columns)
line += row[column] + "\t";
Console.WriteLine(line);
}
// Name Age Job
// AAA 22 PPP
// BBB 25 QQQ
// CCC 38 RRR
}
You can determine the DataTable column names and types dynamically once deserialized.
In Swift 5, use in the below:
DispatchQueue.main.asyncAfter(deadline: .now() + 0.2, execute: closure)
// time gap, specify unit is second
DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(2)) {
Singleton.shared().printDate()
}
// default time gap is second, you can reduce it
DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
// just do it!
}
There are few properties to set to make a Hive table support ACID properties and to insert the values into tables as like in SQL .
Conditions to create a ACID table in Hive.
Properties to set to create ACID table:
set hive.support.concurrency =true;
set hive.enforce.bucketing =true;
set hive.exec.dynamic.partition.mode =nonstrict
set hive.compactor.initiator.on = true;
set hive.compactor.worker.threads= 1;
set hive.txn.manager = org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
set the property hive.in.test to true in hive.site.xml
After setting all these properties , the table should be created with tblproperty 'transactional' ='true'. The table should be bucketed and saved as orc
CREATE TABLE table_name (col1 int,col2 string, col3 int) CLUSTERED BY col1 INTO 4
BUCKETS STORED AS orc tblproperties('transactional' ='true');
Now its possible to inserte values into the table like SQL query.
INSERT INTO TABLE table_name VALUES (1,'a',100),(2,'b',200),(3,'c',300);
Wrap the value passed in different classes that might be helpful doing the trick, check below for more real example:
class Ref<T>{
T s;
public void set(T value){
s = value;
}
public T get(){
return s;
}
public Ref(T value) {
s = value;
}
}
class Out<T>{
T s;
public void set(T value){
s = value;
}
public T get(){
return s;
}
public Out() {
}
}
public static void doAndChangeRefs (Ref<String> str, Ref<Integer> i, Out<String> str2){
//refs passed .. set value
str.set("def");
i.set(10);
//out param passed as null .. instantiate and set
str2 = new Out<String>();
str2.set("hello world");
}
public static void main(String args[]) {
Ref<Integer> iRef = new Ref<Integer>(11);
Out<String> strOut = null;
doAndChangeRefs(new Ref<String>("test"), iRef, strOut);
System.out.println(iRef.get());
System.out.println(strOut.get());
}

ObjectReader reader = new ObjectMapper().readerFor(Map.class);
Map<String, String> map = reader.readValue("{\"foo\":\"val\"}");
Note that reader
instance is Thread Safe.
C does not have the support for strings that some other languages have. A string in C is just a pointer to an array of char
that is terminated by the first null character. There is no string concatenation operator in C.
Use strcat
to concatenate two strings. You could use the following function to do it:
#include <stdlib.h>
#include <string.h>
char* concat(const char *s1, const char *s2)
{
char *result = malloc(strlen(s1) + strlen(s2) + 1); // +1 for the null-terminator
// in real code you would check for errors in malloc here
strcpy(result, s1);
strcat(result, s2);
return result;
}
This is not the fastest way to do this, but you shouldn't be worrying about that now. Note that the function returns a block of heap allocated memory to the caller and passes on ownership of that memory. It is the responsibility of the caller to free
the memory when it is no longer needed.
Call the function like this:
char* s = concat("derp", "herp");
// do things with s
free(s); // deallocate the string
If you did happen to be bothered by performance then you would want to avoid repeatedly scanning the input buffers looking for the null-terminator.
char* concat(const char *s1, const char *s2)
{
const size_t len1 = strlen(s1);
const size_t len2 = strlen(s2);
char *result = malloc(len1 + len2 + 1); // +1 for the null-terminator
// in real code you would check for errors in malloc here
memcpy(result, s1, len1);
memcpy(result + len1, s2, len2 + 1); // +1 to copy the null-terminator
return result;
}
If you are planning to do a lot of work with strings then you may be better off using a different language that has first class support for strings.
int a = fork();
Creates a duplicate process "clone?", which shares the execution stack. The difference between the parent and the child is the return value of the function.
The child getting 0 returned, and the parent getting the new pid.
Each time the addresses and the values of the stack variables are copied. The execution continues at the point it already got to in the code.
At each fork
, only one value is modified - the return value from fork
.
Be aware of the position of pop:
Put the key you want to delete after pop()
orig_dict['AAAAA'] = orig_dict.pop('A')
orig_dict = {'A': 1, 'B' : 5, 'C' : 10, 'D' : 15}
# printing initial
print ("original: ", orig_dict)
# changing keys of dictionary
orig_dict['AAAAA'] = orig_dict.pop('A')
# printing final result
print ("Changed: ", str(orig_dict))
Based on your comment to Issun:
Thanks for the explanation. In my case, The object is declared and created prior to the If condition. So, How do I use If condition to check for < No Variables> ? In other words, I do not want to execute My_Object.Compute if My_Object has < No Variables>
You need to check one of the properties of the object. Without telling us what the object is, we cannot help you.
I did test several common objects and found that an instantiated Collection
with no items added shows <No Variables>
in the watch window. If your object is indeed a collection, you can check for the <No Variables>
condition using the .Count
property:
Sub TestObj()
Dim Obj As Object
Set Obj = New Collection
If Obj Is Nothing Then
Debug.Print "Object not instantiated"
Else
If Obj.Count = 0 Then
Debug.Print "<No Variables> (ie, no items added to the collection)"
Else
Debug.Print "Object instantiated and at least one item added"
End If
End If
End Sub
It is also worth noting that if you declare any object As New
then the Is Nothing
check becomes useless. The reason is that when you declare an object As New
then it gets created automatically when it is first called, even if the first time you call it is to see if it exists!
Dim MyObject As New Collection
If MyObject Is Nothing Then ' <--- This check always returns False
This does not seem to be the cause of your specific problem. But, since others may find this question through a Google search, I wanted to include it because it is a common beginner mistake.
Simply
var ary = ['three', 'seven', 'eleven'];
var index = ary.indexOf('seven'); // get index if value found otherwise -1
if (index > -1) { //if found
ary.splice(index, 1);
}
The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:
XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
where xml2.Element("ID").Value == variable
select xml2).FirstOrDefault();
This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

For making a call activity using intents, you should request the proper permissions.
For that you include uses permissions in AndroidManifest.xml file.
<uses-permission android:name="android.permission.CALL_PHONE" />
Then include the following code in your activity
if (ActivityCompat.checkSelfPermission(mActivity,
Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
//Creating intents for making a call
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
mActivity.startActivity(callIntent);
}else{
Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}
On the model set $incrementing
to false
public $incrementing = false;
This will stop it from thinking it is an auto increment field.
Define what GetData is. At the moment it is not defined.
Function getData(currentWorksheet as Worksheet, dataStartRow as Integer, dataEndRow as Integer, DataStartCol as Integer, dataEndCol as Integer) as variant
You can also use pageMethods in asp.net. So that you can call javascript functions from asp.net functions. E.g.
[WebMethod]_x000D_
public static string showTxtbox(string name)_x000D_
{_x000D_
return showResult(name);_x000D_
}_x000D_
_x000D_
public static string showResult(string name)_x000D_
{_x000D_
Database databaseObj = new Database();_x000D_
DataTable dtObj = databaseObj.getMatches(name);_x000D_
_x000D_
string result = "<table border='1' cellspacing='2' cellpadding='2' >" +_x000D_
"<tr>" +_x000D_
"<td><b>Name</b></td>" +_x000D_
"<td><b>Company Name</b></td>" +_x000D_
"<td><b>Phone</b></td>"+_x000D_
"</tr>";_x000D_
_x000D_
for (int i = 0; i < dtObj.Rows.Count; i++)_x000D_
{_x000D_
result += "<tr> <td><a href=\"javascript:link('" + dtObj.Rows[i][0].ToString().Trim() + "','" +_x000D_
dtObj.Rows[i][1].ToString().Trim() +"','"+dtObj.Rows[i][2]+ "');\">" + Convert.ToString(dtObj.Rows[i]["name"]) + "</td>" +_x000D_
"<td>" + Convert.ToString(dtObj.Rows[i]["customerCompany"]) + "</td>" +_x000D_
"<td>"+Convert.ToString(dtObj.Rows[i]["Phone"])+"</td>"+_x000D_
"</tr>";_x000D_
}_x000D_
_x000D_
result += "</table>";_x000D_
return result;_x000D_
}
_x000D_
Here above code is written in .aspx.cs page. Database is another class. In showResult() function I've called javascript's link() function. Result is displayed in the form of table.
