You must link an event in your onClick. Additionally, the click function must receive the event. See the example
export default function Component(props) {
function clickEvent (event, variable){
console.log(variable);
}
return (
<div>
<IconButton
key="close"
aria-label="Close"
color="inherit"
onClick={e => clickEvent(e, 10)}
>
</div>
)
}
First delete node_modules
folder
then Restart system
Run npm install --save-dev @angular-devkit/build-angular
and
Run npm install
For Angular 9+ You can add headers and params directly without the key-value notion:
const headers = new HttpHeaders().append('header', 'value');
const params = new HttpParams().append('param', 'value');
this.http.get('url', {headers, params});
In such case look at gradle console
it will show the issue in detail with exact location which led to this compilation error.
In my case I was using Butterknife
in one of my class and I had auto-converted
that class to kotlin
using android studio's utility

As in my log it clearly shows issues are with declaration of variables with butterknife. So I looked into this issue and was able to solve it.
I came here with similar error:
System.InvalidOperationException: 'The entity type 'MyType' requires a primary key to be defined.'
After reading answer by hvd, realized I had simply forgotten to make my key property 'public'. This..
namespace MyApp.Models.Schedule
{
public class MyType
{
[Key]
int Id { get; set; }
// ...
Should be this..
namespace MyApp.Models.Schedule
{
public class MyType
{
[Key]
public int Id { get; set; } // must be public!
// ...
Had the same issue with typescript and the aws-sdk
. The solve was to change the target to es6
.
My complete tsconfig.json
file:
{
compilerOptions: {
outDir: ./dist/,
sourceMap: true,
noImplicitAny: true,
module: commonjs,
target: es6,
jsx: react,
allowJs: true
},
include: [
./src/**/*
]
}
you could also just have a return div like the one below and use the built in template literals of Javascript :
const tifs = {1: 'Joe', 2: 'Jane'};
return(
<div>
{Object.keys(tifOptions).map((key)=>(
<p>{paragraphs[`${key}`]}</p>
))}
</div>
)
If you have > 20 minsdkversion, you need to use the latest Firebase Auth version i.e.
implementation 'com.google.firebase:firebase-auth:18.1.0'
and no need to setup multi-dex if you don't actually need it.
I encountered this issue when I've used 16.0.5 from the Firebase helper but was able to fix it when I've updated to 18.1.0.
I had it when I did so :
function foo() (...) export default foo
correctly:
export default () =>(...);
or
const foo = ...
export default foo
I added the following code in proguard file.
-keep public class * extends android.app.Activity_x000D_
-keep public class * extends android.app.Application
_x000D_
and it worked in my case.
You have two options here, 1. Use for
instead for foreach
for iteration.But in your case the collection is IEnumerable and the upper limit of the collection is unknown so foreach will be the best option. so i prefer to use another integer variable to hold the iteration count: here is the code for that:
int i = 0; // for index
foreach (var row in list)
{
bool IsChecked;// assign value to this variable
if (IsChecked)
{
// use i value here
}
i++; // will increment i in each iteration
}
No matching client found for package name 'com.tf' I am pretty sure that the "package_name" in google-services.json is not matching with your "applicationId" in app gradle.
app gradle:
defaultConfig {
applicationId "com.tf" //replace with the package_name in google-services.json =
minSdkVersion 23
targetSdkVersion 26
versionCode 7
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
google-services.json
"client_info": {
"mobilesdk_app_id": "1:23978655351:android:2b2fece6b961cc70",
"android_client_info": {
"package_name": "in.ac.geu.debug"
}
},
Solution: Just make sure the package_name
and applicationId
must be same.
This will work but the element will still in the DOM.
.hidden {
display: none;
}
<div [class.hidden]="!show" *ngFor="let thing of stuff">
{{log(thing)}}
<span>{{thing.name}}</span>
</div>
you can use LayoutInflater to inflate your dynamic data as a layout file.
UPDATE : first create a LinearLayout inside your CardView's layout and assign an ID for it.
after that create a layout file that you want to inflate. at last in your onBindViewHolder
method in your "RAdaper" class. write these codes :
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = mInflater.inflate(R.layout.my_list_custom_row, parent, false);
after that you can initialize data and ClickListeners with your RAdapter Data. hope it helps.
Just add the line in you file,
import 'rxjs/Rx';
It will import bunch of dependencies.Tested in angular 5
Don't edit the vector assets directly. If you're using a vector drawable in an ImageButton, just choose your color in android:tint
.
<ImageButton
android:layout_width="48dp"
android:layout_height="48dp"
android:id="@+id/button"
android:src="@drawable/ic_more_vert_24dp"
android:tint="@color/primary" />
In my case I was using jackson-databind-2.8.8.jar
that is not compatible with JDK 1.6
I need to use so Spring wasn't loading this converter. I downgraded the version and it works now.
On Android >=6.0, We have to request permission runtime.
Step1: add in AndroidManifest.xml file
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Step2: Request permission.
int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);
if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE);
} else {
//TODO
}
Step3: Handle callback when you request permission.
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case REQUEST_READ_PHONE_STATE:
if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
//TODO
}
break;
default:
break;
}
}
Edit: Read official guide here Requesting Permissions at Run Time
A much simpler solution to this problem that allows letters, numbers and words as the label is the following code. More specifically, the line of code starting with "icon:". Any string or variable could be substituted for 'k'.
for (i = 0; i < locations.length; i++)
{
k = i + 1;
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=' + k + '|FF0000|000000'
});
--- the locations array holds the lat and long and k is the row number for the address I was mapping. In other words if I had a 100 addresses to map my marker labels would be 1 to 100.
You are not leveraging async / await effectively because the request thread will be blocked while executing the synchronous method ReturnAllCountries()
The thread that is assigned to handle a request will be idly waiting while ReturnAllCountries()
does it's work.
If you can implement ReturnAllCountries()
to be asynchronous, then you would see scalability benefits. This is because the thread could be released back to the .NET thread pool to handle another request, while ReturnAllCountries()
is executing. This would allow your service to have higher throughput, by utilizing threads more efficiently.
from Tkinter import *
app = Tk()
# Text Widget + Font Size
txt = Text(app, font=('Verdana',8))
txt.pack()
# Delete Button
btn = Button(app, text='Delete', command=lambda: txt.delete(1.0,END))
btn.pack()
app.mainloop()
Here's an example of txt.delete(1.0,END)
as mentioned.
The use of lambda
makes us able to delete the contents without defining an actual function.
<Scatter
data={data}
// style={{ width: "50%", height: "50%" }}
options={{
scales: {
yAxes: [
{
scaleLabel: {
display: true,
labelString: "Probability",
},
},
],
xAxes: [
{
scaleLabel: {
display: true,
labelString: "Hours",
},
},
],
},
}}
/>
You can also modify your theme using theme Editor by clicking :
Tools -> Android -> Theme Editor
Then, you don't even need to put some extra content in your .xml or .class files.
Use backgroundTint
instead of background
I was facing the same issue. I tried below solution : 1. deleted create table code from Up() and related code from Down() method 2. Run update-database command in Package Manager Consol
this solved my problem
Another example using PowerShell for set permissions (File / Directory) :
Get-Acl "C:\file.txt" | fl *
$acl = Get-Acl "C:\file.txt"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule("everyone","FullControl","Allow")
$acl.SetAccessRule($accessRule)
$acl | Set-Acl "C:\file.txt"
Hope this helps
Taking the other answer, here is a quick fix if you want to get a list with random colors for each bar:
function getRandomColor(n) {
var letters = '0123456789ABCDEF'.split('');
var color = '#';
var colors = [];
for(var j = 0; j < n; j++){
for (var i = 0; i < 6; i++ ) {
color += letters[Math.floor(Math.random() * 16)];
}
colors.push(color);
color = '#';
}
return colors;
}
Now you could use this function in the backgroundColor field in data:
data: {
labels: count[0],
datasets: [{
label: 'Registros en BDs',
data: count[1],
backgroundColor: getRandomColor(count[1].length)
}]
}
Ok - for me the source of the problem was in serialisation/deserialisation. The object that was being sent and received was as follows where the code is submitted and the code and maskedPhoneNumber is returned.
@ApiObject(description = "What the object is for.")
@JsonIgnoreProperties(ignoreUnknown = true)
public class CodeVerification {
@ApiObjectField(description = "The code which is to be verified.")
@NotBlank(message = "mandatory")
private final String code;
@ApiObjectField(description = "The masked mobile phone number to which the code was verfied against.")
private final String maskedMobileNumber;
public codeVerification(@JsonProperty("code") String code, String maskedMobileNumber) {
this.code = code;
this.maskedMobileNumber = maskedMobileNumber;
}
public String getcode() {
return code;
}
public String getMaskedMobileNumber() {
return maskedMobileNumber;
}
}
The problem was that I didn't have a JsonProperty defined for the maskedMobileNumber in the constructor. i.e. Constructor should have been
public codeVerification(@JsonProperty("code") String code, @JsonProperty("maskedMobileNumber") String maskedMobileNumber) {
this.code = code;
this.maskedMobileNumber = maskedMobileNumber;
}
I recommend you to remove scipy via
apt-get purge scipy
and then to install it by
pip install scipy
If you do both then you might confuse you deb package manager due to possibly differing versions.
I have solved this problem by adding one line code in cURL script:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
Warning: This makes the request absolute insecure (see answer by @YSU)!
Have a look at the documentation. You made the following mistakes.
Firstly, ps.executeQuery()
doesn't have any parameters. Instead you passed the SQL query into it.
Secondly, regarding the prepared statement, you have to use the ?
symbol if want to pass any parameters. And later bind it using
setXXX(index, value)
Here xxx stands for the data type.
Both classes Rectangle and Ellipse need to override both of the abstract methods.
To work around this, you have 3 options:
Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:
abstract class Shape {
// ...
void draw(Graphics g);
}
And
class Rectangle extends Shape {
void draw(Graphics g) {
// ...
}
}
Finally
class Ellipse extends Shape {
void draw(Graphics g) {
// ...
}
}
And you can switch in between them, like so:
Shape shape = new Ellipse();
shape.draw(/* ... */);
shape = new Rectangle();
shape.draw(/* ... */);
Again, just an example.
Faced this issue of removing the labels in Chartjs now. Looks like the documentation is improved. http://www.chartjs.org/docs/#getting-started-global-chart-configuration
Chart.defaults.global.legend.display = false;
this global settings prevents legends from being shown in all Charts. Since this was enough for me, I used it. I am not sure to how to avoid legends for individual charts.
If you by any chance using java for configuration, you may need to check the below bean
declaration if you have package level changes. Eg: com.abc.spring
package changed to com.bbc.spring
@Bean
public SessionFactory sessionFactory() {
LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource());
//builder.scanPackages("com.abc.spring"); //Comment this line as this package no longer valid.
builder.scanPackages("com.bbc.spring");
builder.addProperties(getHibernationProperties());
return builder.buildSessionFactory();
}
In pandas 0.20.2
you can do:
from pandas.api.types import is_string_dtype
from pandas.api.types import is_numeric_dtype
is_string_dtype(df['A'])
>>>> True
is_numeric_dtype(df['B'])
>>>> True
So your code becomes:
for y in agg.columns:
if (is_string_dtype(agg[y])):
treat_str(agg[y])
elif (is_numeric_dtype(agg[y])):
treat_numeric(agg[y])

JObject implements IDictionary, so you can use it that way. For ex,
var cycleJson = JObject.Parse(@"{""name"":""john""}");
//add surname
cycleJson["surname"] = "doe";
//add a complex object
cycleJson["complexObj"] = JObject.FromObject(new { id = 1, name = "test" });
So the final json will be
{
"name": "john",
"surname": "doe",
"complexObj": {
"id": 1,
"name": "test"
}
}
You can also use dynamic
keyword
dynamic cycleJson = JObject.Parse(@"{""name"":""john""}");
cycleJson.surname = "doe";
cycleJson.complexObj = JObject.FromObject(new { id = 1, name = "test" });
Did you add firefox to your path after you have started the selenium server? If that is the case selenium will still use old path. The solution is to tear down & restart selenium so that it will use the updated Path environment variable.
To check if firefox is added in your path correctly you can just launch a command line terminal "cmd" and type "firefox" + ENTER there. If firefox starts then everything is alright and restarting selenium server should fix the problem.
Basic method for beginners like me.
public void loadDataToJtable(ArrayList<String> liste){
rows = table.getRowCount();
cols = table.getColumnCount();
for (int i = 0; i < rows ; i++) {
for ( int k = 0; k < cols ; k++) {
for (int h = 0; h < list1.size(); h++) {
String b = list1.get(h);
b = table.getValueAt(i, k).toString();
}
}
}
}
Another cause of this could be if you don't use the default variable name for the "id" which is actually: id.
In my case the issue was resolved by installing Oracle's official JDK 10 as opposed to using the default OpenJDK that came with my Ubuntu. This is the guide I followed: https://www.linuxuprising.com/2018/04/install-oracle-java-10-in-ubuntu-or.html
It seems many users are having issues with this. Here are some fixes:
Right click on your task > "Properties" > "Actions" > "Edit" | Put ONLY the file name under 'Program/Script', no quotes and ONLY the directory under 'Start in' as described, again no quotes.
Right click on your task > "Properties" > "General" | Test with any/all of the following:
If you are trying to make more than just one folder on the root of the sdcard,
ex. Environment.getExternalStorageDirectory() + "/Example/Ex App/"
then instead of folder.mkdir()
you would use folder.mkdirs()
I've made this mistake in the past & I took forever to figure it out.
This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):
It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.
Here are the commands again for easier copy-pasting:
openssl rsa -in $FF -out $TF
openssl rsa -aes256 -in $FF -out $TF
openssl pkcs8 -topk8 -nocrypt -in $FF -out $TF
openssl pkcs8 -topk8 -v2 aes-256-cbc -v2prf hmacWithSHA256 -in $FF -out $TF
and
openssl rsa -check -in $FF
openssl rsa -text -in $FF
To help other bug-hunters. I had this error because the function didn't exist.

As Gyrocode.com said "Most likely your table is hidden initially which prevents jQuery DataTables from calculating column widths."
I had this problem too and solved it by just init the dataTable after showing the div
For example
$('#my_div').show();
$('#my_table').DataTable();
I was having the same issue and this works excellently.

app.set('view engine', 'html');
app.engine('html', require('ejs').renderFile);
Our solution, adding some validations to response so we are sure we have a well formed json object in $json variable
$ch = curl_init();

For debugging when I start java add like mentioned:
-Djavax.net.debug=ssl
then you can see that the browser tried to use TLSv1 and Jetty 9.1.3 was talking TLSv1.2 so they were not communicating. That's Firefox. Chrome wanted SSLv3 so I added that also.
sslContextFactory.setIncludeProtocols( "TLSv1", "SSLv3" ); <-- Fix
sslContextFactory.setRenegotiationAllowed(true); <-- added don't know if helps anything.
I did not do most of the other stuff the orig poster did:
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] {
or this answer:
KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory
.getDefaultAlgorithm());
or
.setEnabledCipherSuites
I created one self signed cert like this: (but I added .jks to filename) and read that in my jetty java code. http://www.eclipse.org/jetty/documentation/current/configuring-ssl.html
keytool -keystore keystore.jks -alias jetty -genkey -keyalg RSA

Don't manually edit the .designer files in visual studio that usually leads to headaches. Instead either specify it in the properties section of your DataGridRow which should be contained within a DataGrid element. Or if you just want VS to do it for you find the double click event within the properties page->events (little lightning bolt icon) and double click the text area where you would enter a function name for that event.
This link should help
http://msdn.microsoft.com/en-us/library/6w2tb12s(v=vs.90).aspx
You need to do two additional things after following the link that you have mentioned in your post:
One have to map the changed login cridentials in phpmyadmin's config.inc.php
and second, you need to restart your web and mysql servers..
php version is not the issue here..you need to go to phpmyadmin installation directory and find file config.inc.php
and in that file put your current mysql password at line
$cfg['Servers'][$i]['user'] = 'root'; //mysql username here
$cfg['Servers'][$i]['password'] = 'password'; //mysql password here
Java and HTTPS url connection without downloading certificate
If you really want to avoid downloading the server's certificate, then use an anonymous protocol like Anonymous Diffie-Hellman (ADH). The server's certificate is not sent with ADH and friends.
You select an anonymous protocol with setEnabledCipherSuites
. You can see the list of cipher suites available with getEnabledCipherSuites
.
Related: that's why you have to call SSL_get_peer_certificate
in OpenSSL. You'll get a X509_V_OK
with an anonymous protocol, and that's how you check to see if a certificate was used in the exchange.
But as Bruno and Stephed C stated, its a bad idea to avoid the checks or use an anonymous protocol.
Another option is to use TLS-PSK or TLS-SRP. They don't require server certificates either. (But I don't think you can use them).
The rub is, you need to be pre-provisioned in the system because TLS-PSK is Pres-shared Secret and TLS-SRP is Secure Remote Password. The authentication is mutual rather than server only.
In this case, the mutual authentication is provided by a property that both parties know the shared secret and arrive at the same premaster secret; or one (or both) does not and channel setup fails. Each party proves knowledge of the secret is the "mutual" part.
Finally, TLS-PSK or TLS-SRP don't do dumb things, like cough up the user's password like in a web app using HTTP (or over HTTPS). That's why I said each party proves knowledge of the secret...
You can do this in a number of ways. You can use databinding (typical initialized after InitializeComponent();)
textBox1.DataBindings.Add(new Binding("Text", yourBindingSource,
"TableName.ColumnName", true, DataSourceUpdateMode.OnPropertyChanged));
or use a DataLayoutControl (if you are going to use textbox for editing, I really recommend spending some time to learn how to use this component.
or in FocusedRowChanged by assigning from one of these methods:
textBox1.Text = gridView1.GetDataRow(e.FocusedRowHandle)["Name"].ToString();
textBox1.Text = gridView1.GetFocusedDataRow()["Name"].ToString();
textBox1.Text = (gridView1.GetFocusedRow() as DataRowView).Row["Name"].ToString();
textBox1.Text = gridView1.GetFocusedRowCellValue("Name").ToString();
Your Button2Click
and Button3Click
functions pass klad.xls
and smimime.txt
. These files most likely aren't actual executables indeed.
In order to open arbitrary files using the application associated with them, use ShellExecute
while (rs.next()) {
customer.setId(rs.getInt("id"));
customer.setName(rs.getString("name"));
customer.setAddress(rs.getString("address"));
customer.setPhone(rs.getString("phone"));
customer.setEmail(rs.getString("email"));
customer.setBountPoints(rs.getInt("bonuspoint"));
customer.setTotalsale(rs.getInt("totalsale"));
customers.add(customer);
customer = null;
}
Try replacing your while loop code with above mentioned code. Here what we have done is after doing customers.add(customer)
we are doing customer = null;`
I was getting this same error and searching for it led me here. My fix appeared to be simply to add @Component annotation to the implementation of the abstract service.
In this case, that would look like:
import org.springframework.stereotype.Component;
...
@Component
public class ContactServiceImpl implements ContactService {
public ActionResult SomeAction(string start, string end)
The framework will map the query string parameters to the method parameters.
Simple solution would be as below. This is improvement of solution from vale.
private void dgMapTable_SelectionChanged(object sender, EventArgs e)
{
int active_map=0;
if(dgMapTable.SelectedRows.Count>0)
active_map = dgMapTable.SelectedRows[0].Index;
// User code if required Process_ROW(active_map);
}
Note for other reader, for above code to work FullRowSelect
selection mode for datagridview should be used. You may extend this to give message if more than two rows selected.
Check if you are returning a @ResponseBody or a @ResponseStatus
I had a similar problem. My Controller looked like that:
@RequestMapping(value="/user", method = RequestMethod.POST)
public String updateUser(@RequestBody User user){
return userService.updateUser(user).getId();
}
When calling with a POST request I always got the following error:
HTTP Status 405 - Request method 'POST' not supported
After a while I figured out that the method was actually called, but because there is no @ResponseBody and no @ResponseStatus Spring MVC raises the error.
To fix this simply add a @ResponseBody
@RequestMapping(value="/user", method = RequestMethod.POST)
public @ResponseBody String updateUser(@RequestBody User user){
return userService.updateUser(user).getId();
}
or a @ResponseStatus to your method.
@RequestMapping(value="/user", method = RequestMethod.POST)
@ResponseStatus(value=HttpStatus.OK)
public String updateUser(@RequestBody User user){
return userService.updateUser(user).getId();
}
Don't believe all those who try to mislead you.
In your request, just add:
ca: [fs.readFileSync([certificate path], {encoding: 'utf-8'})]
If you turn on unauthorized certificates, you will not be protected at all (exposed to MITM for not validating identity), and working without SSL won't be a big difference. The solution is to specify the CA certificate that you expect as shown in the next snippet. Make sure that the common name of the certificate is identical to the address you called in the request(As specified in the host):
What you will get then is:
var req = https.request({
host: '192.168.1.1',
port: 443,
path: '/',
ca: [fs.readFileSync([certificate path], {encoding: 'utf-8'})],
method: 'GET',
rejectUnauthorized: true,
requestCert: true,
agent: false
},
Please read this article (disclosure: blog post written by this answer's author) here in order to understand:
This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.
Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:
http://pauljacobson.org/2010/01/22/2010122firefox-and-its-limited-html-5-video-support-html/
Please make sure that your applicationContext.xml file is loaded by specifying it in your web.xml file:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
You can make use of the Support Library's NestedScrollView
and it's NestedScrollView.OnScrollChangeListener
interface.
https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
Alternatively if your app is targeting API 23 or above, you can make use of the following method on the ScrollView
:
View.setOnScrollChangeListener(OnScrollChangeListener listener)
Then follow the example that @Fustigador described in his answer. Note however that as @Will described, you should consider adding a small buffer in case the user or system isn't able to reach the complete bottom of the list for any reason.
Also worth noting is that the scroll change listener will sometimes be called with negative values or values greater than the view height. Presumably these values represent the 'momentum' of the scroll action. However unless handled appropriately (floor / abs) they can cause problems detecting the scroll direction when the view is scrolled to the top or bottom of the range.
To get back to the parent frame, use:
driver.switchTo().parentFrame();
To get back to the first/main frame, use:
driver.switchTo().defaultContent();
Not sure what you meant, but you can permanently turn showing whitespaces on and off in Settings -> Editor -> General -> Appearance -> Show whitespaces
.
Also, you can set it for a current file only in View -> Active Editor -> Show WhiteSpaces
.
Edit:
Had some free time since it looks like a popular issue, I had written a plugin to inspect the code for such abnormalities. It is called Zero Width Characters locator and you're welcome to give it a try.
The problem is that you are calling GetGridData
from a background thread. This method accesses several WPF controls which are bound to the main thread. Any attempt to access them from a background thread will lead to this error.
In order to get back to the correct thread you should use SynchronizationContext.Current.Post
. However in this particular case it seems like the majority of the work you are doing is UI based. Hence you would be creating a background thread just to go immediately back to the UI thread and do some work. You need to refactor your code a bit so that it can do the expensive work on the background thread and then post the new data to the UI thread afterwards
I was having this problem with Android Studio when I'm behind a proxy. I was using Crashlytics that tries to upload the mapping file during a build.
I added the missing proxy certificate to the truststore located at
/Users/[username]/Documents/Android Studio.app/Contents/jre/jdk/Contents/Home/jre/lib/security/cacerts
with the following command: keytool -import -trustcacerts -keystore cacerts -storepass [password] -noprompt -alias [alias] -file [my_certificate_location]
for example with the default truststore password
keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias myproxycert -file /Users/myname/Downloads/MyProxy.crt
I encountered the same problem when I built an application on a Windows 7 box that had previously been maintained on an XP machine.
The program ran fine when built for Debug, but failed with this error when built for Release. I found the answer on the project's Properties page. Go to the "Build" tab and try changing the Platform Target from "Any CPU" to "x86".
You could just use
DataGridView1.CurrentRow.Cells["ColumnName"].Value
From my experience, won't recommend my below answer for any public facing Web applications.
If you need it for your inhouse tools or for Testing, I would recommend to share it on your own machine.
-Right click on the root path you need to access
-Choose Properties
-Click on Share button and add your chosen users who can access it
This will then create a shared directory like \\{PCName}\{YourSharedRootDirectory} This could be definitely much less than your full path I hope, for me I could reduce to 30 characters from about 290 characters. :)
You should use the options 'year', 'month', and 'date' when initializing to specify the initial date value used by fullcalendar:
$('#calendar').fullCalendar({
year: 2012,
month: 4,
date: 25
}); // This will initialize for May 25th, 2012.
See the function setYMD(date,y,m,d)
in the fullcalendar.js
file; note that the JavaScript setMonth, setDate, and setFullYear functions are used, so your month value needs to be 0-based (Jan is 0).
UPDATE: As others have noted in the comments, the correct way now (V3 as of writing this edit) is to initialize the defaultDate property to a value that is
anything the Moment constructor accepts, including an ISO8601 date string like "2014-02-01"
as it uses Moment.js. Documentation here.
Updated example:
$('#calendar').fullCalendar({
defaultDate: "2012-05-25"
}); // This will initialize for May 25th, 2012.
You cannot supply system properties to the jarsigner.exe tool, unfortunately.
I have submitted defect 7177232, referencing @eckes' defect 7127374 and explaining why it was closed in error.
My defect is specifically about the impact on the jarsigner tool, but perhaps it will lead them to reopening the other defect and addressing the issue properly.
UPDATE: Actually, it turns out that you CAN supply system properties to the Jarsigner tool, it's just not in the help message. Use jarsigner -J-Djsse.enableSNIExtension=false
This is "By Design". The parseFloat
function will only consider the parts of the string up until in reaches a non +, -, number, exponent or decimal point. Once it sees the comma it stops looking and only considers the "75" portion.
To fix this convert the commas to decimal points.
var fullcost = parseFloat($("#fullcost").text().replace(',', '.'));
The answer above is correct, but in terms of the workaround, I had problems with the BouncyCastle implementation when I set it as preferred provider:
java.lang.ArrayIndexOutOfBoundsException: 64
at com.sun.crypto.provider.TlsPrfGenerator.expand(DashoA13*..)
This is also discussed in one forum thread I found, which doesn't mention a solution. http://www.javakb.com/Uwe/Forum.aspx/java-programmer/47512/TLS-problems
I found an alternative solution which works for my case, although I'm not at all happy with it. The solution is to set it so that the Diffie-Hellman algorithm is not available at all. Then, supposing the server supports an alternative algorithm, it will be selecting during normal negotiation. Obviously the downside of this is that if somebody somehow manages to find a server that only supports Diffie-Hellman at 1024 bits or less then this actually means it will not work where it used to work before.
Here is code which works given an SSLSocket (before you connect it):
List<String> limited = new LinkedList<String>();
for(String suite : ((SSLSocket)s).getEnabledCipherSuites())
{
if(!suite.contains("_DHE_"))
{
limited.add(suite);
}
}
((SSLSocket)s).setEnabledCipherSuites(limited.toArray(
new String[limited.size()]));
Nasty.
Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.
First, some definitions:
Bar
is a TypeName in Public Class Bar
, or in Dim Foo as Bar
. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.System.Type
objects which contain a value. This value indicates a type; just like a String
would take some text or an Int
would take a number, except we are storing types instead of text or numbers. Type
objects contain the type definitions, as well as its corresponding TypeName.Second, the theory:
Foo.GetType()
returns a Type
object which contains the type for the variable Foo
. In other words, it tells you what Foo
is an instance of.GetType(Bar)
returns a Type
object which contains the type for the TypeName Bar
.In some instances, the type an object has been Cast
to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer
cast into an Object
:
Dim MyVal As Integer = 42
Dim MyObj As Object = CType(MyVal, Object)
So, is MyObj
of type Object
or of type Integer
? MyObj.GetType()
will tell you it is an Integer
.
Type Of Foo Is Bar
feature, which allows you to ascertain a variable Foo
is compatible with a TypeName Bar
. Type Of MyObj Is Integer
and Type Of MyObj Is Object
will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it.
More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarksThe test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.
Public Sub TestMethod1()
Dim MyValInt As Integer = 42
Dim MyValDble As Double = CType(MyValInt, Double)
Dim MyObj As Object = CType(MyValDble, Object)
Debug.Print(MyValInt.GetType.ToString) 'Returns System.Int32
Debug.Print(MyValDble.GetType.ToString) 'Returns System.Double
Debug.Print(MyObj.GetType.ToString) 'Returns System.Double
Debug.Print(MyValInt.GetType.GetType.ToString) 'Returns System.RuntimeType
Debug.Print(MyValDble.GetType.GetType.ToString) 'Returns System.RuntimeType
Debug.Print(MyObj.GetType.GetType.ToString) 'Returns System.RuntimeType
Debug.Print(GetType(Integer).GetType.ToString) 'Returns System.RuntimeType
Debug.Print(GetType(Double).GetType.ToString) 'Returns System.RuntimeType
Debug.Print(GetType(Object).GetType.ToString) 'Returns System.RuntimeType
Debug.Print(MyValInt.GetType = GetType(Integer)) '# Returns True
Debug.Print(MyValInt.GetType = GetType(Double)) 'Returns False
Debug.Print(MyValInt.GetType = GetType(Object)) 'Returns False
Debug.Print(MyValDble.GetType = GetType(Integer)) 'Returns False
Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False
Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False
Debug.Print(MyObj.GetType = GetType(Double)) '# Returns True
Debug.Print(MyObj.GetType = GetType(Object)) 'Returns False
Debug.Print(TypeOf MyObj Is Integer) 'Returns False
Debug.Print(TypeOf MyObj Is Double) '# Returns True
Debug.Print(TypeOf MyObj Is Object) '# Returns True
End Sub
EDIT
You can also use Information.TypeName(Object)
to get the TypeName of a given object. For example,
Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"
You can also do it by checking if View's indexOfView method if indexOfView method returns -1 then we can use.
ViewGroup's detachViewFromParent(v); followed by ViewGroup's removeDetachedView(v, true/false);
I created a category around UIButton to be able to set the background color of the button and set the state. You might find this useful.
@implementation UIButton (ButtonMagic)
- (void)setBackgroundColor:(UIColor *)backgroundColor forState:(UIControlState)state {
[self setBackgroundImage:[UIButton imageFromColor:backgroundColor] forState:state];
}
+ (UIImage *)imageFromColor:(UIColor *)color {
CGRect rect = CGRectMake(0, 0, 1, 1);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
This will be part of a set of helper categories I'm open sourcing this month.
Swift 2.2
extension UIImage {
static func fromColor(color: UIColor) -> UIImage {
let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
UIGraphicsBeginImageContext(rect.size)
let context = UIGraphicsGetCurrentContext()
CGContextSetFillColorWithColor(context, color.CGColor)
CGContextFillRect(context, rect)
let img = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return img
}
}
Swift 3.0
extension UIImage {
static func from(color: UIColor) -> UIImage {
let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
UIGraphicsBeginImageContext(rect.size)
let context = UIGraphicsGetCurrentContext()
context!.setFillColor(color.cgColor)
context!.fill(rect)
let img = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return img!
}
}
Use as
let img = UIImage.from(color: .black)
The PDO solution, just for a better implementation then mysql_*
:
$array = $pdo->query("SELECT id, title, '$year-month-10' as start,url
FROM table")->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($array);
Nice feature is also that it will leave integers as integers as opposed to strings.
I encountered similar issue. The missing artifacts (jar files) exists in ~/.m2 directory and somehow eclipse is unable to find it.
For example: Missing artifact org.jdom:jdom:jar:1.1:compile
I looked through this directory ~/.m2/repository/org/jdom/jdom/1.1 and I noticed there is this file _maven.repositories. I opened it using text editor and saw the following entry:
#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Wed Feb 13 17:12:29 SGT 2013
jdom-1.1.jar>central=
jdom-1.1.pom>central=
I simply removed the "central" word from the file:
#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Wed Feb 13 17:12:29 SGT 2013
jdom-1.1.jar>=
jdom-1.1.pom>=
and run Maven > Update Project from eclipse and it just worked :) Note that your file may contain other keyword instead of "central".
In my case this was actually a symptom of the server, hosted on AWS, lacking an IP for the external network. It would attempt to download namespaces from springframework.org and fail to make a connection.
This is such a common problem, especially in GUI applications, that I'm surprised there isn't a BCL class to do this out of the box. Here's how I do it.
public static class ReflectiveEnumerator
{
static ReflectiveEnumerator() { }
public static IEnumerable<T> GetEnumerableOfType<T>(params object[] constructorArgs) where T : class, IComparable<T>
{
List<T> objects = new List<T>();
foreach (Type type in
Assembly.GetAssembly(typeof(T)).GetTypes()
.Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(T))))
{
objects.Add((T)Activator.CreateInstance(type, constructorArgs));
}
objects.Sort();
return objects;
}
}
A few notes:
Assembly.GetAssembly(typeof(T))
because your base class might be in a different assembly. type.IsClass
and !type.IsAbstract
because it'll throw an exception if you try to instantiate an interface or abstract class.IComparable
so that they can be sorted.System.setProperty("gate.home", "/some/directory");
After that you can retrieve its value later by calling
String value = System.getProperty("gate.home");

Get from Yahoo a JSON or XML that you can parse from a REST query.
You can exchange from any to any currency and even get the date and time of the query using the YQL (Yahoo Query Language).

I stumbled over the same problem today and I guess the real solution to this question is this
<LinearLayout android:id="@+id/container"
android:animateLayoutChanges="true"
...
/>
You will have to set this property for all topmost layouts, which are involved in the shift. If you now set the visibility of one layout to GONE, the other will take the space as the disappearing one is releasing it. There will be a default animation which is some kind of "fading out", but I think you can change this - but the last one I have not tested, for now.

You are looking for System.Reflection.Assembly.GetExecutingAssembly()
string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string xmlFileName = Path.Combine(assemblyFolder,"AggregatorItems.xml");
Note:
The .Location
property returns the location of the currently running DLL file.
Under some conditions the DLL is shadow copied before execution, and the .Location
property will return the path of the copy. If you want the path of the original DLL, use the Assembly.GetExecutingAssembly().CodeBase
property instead.
.CodeBase
contains a prefix (file:\

Example from MVC 4 for dropdownlist validation on Submit using Dataannotation and ViewBag (less line of code)
Models:
namespace Project.Models
{
public class EmployeeReferral : Person
{
public int EmployeeReferralId { get; set; }
//Company District
//List
[Required(ErrorMessage = "Required.")]
[Display(Name = "Employee District:")]
public int? DistrictId { get; set; }
public virtual District District { get; set; }
}
namespace Project.Models
{
public class District
{
public int? DistrictId { get; set; }
[Display(Name = "Employee District:")]
public string DistrictName { get; set; }
}
}
EmployeeReferral Controller:
namespace Project.Controllers
{
public class EmployeeReferralController : Controller
{
private ProjDbContext db = new ProjDbContext();
//
// GET: /EmployeeReferral/
public ActionResult Index()
{
return View();
}
public ActionResult Create()
{
ViewBag.Districts = db.Districts;
return View();
}
View:
<td>
<div class="editor-label">
@Html.LabelFor(model => model.DistrictId, "District")
</div>
</td>
<td>
<div class="editor-field">
@*@Html.DropDownList("DistrictId", "----Select ---")*@
@Html.DropDownListFor(model => model.DistrictId, new SelectList(ViewBag.Districts, "DistrictId", "DistrictName"), "--- Select ---")
@Html.ValidationMessageFor(model => model.DistrictId)
</div>
</td>
Why can't we use ViewBag for populating dropdownlists that can be validated with Annotations. It is less lines of code.
Try this:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
fillButton[i].setBackground(getBaseContext().getResources().getDrawable(R.drawable.drawable_name));
}
else {
fillButton[i].setBackgroundColor(Color.argb(255,193,234,203));
}
You could also use the RenderView Controller extension
from here
(source)
and use it like this:
public ActionResult Do() {
var html = this.RenderView("index", theModel);
...
}
it works for razor and web-forms viewengines

I created a method fixUntrustCertificate(), so when I am dealing with a domain that is not in trusted CAs you can invoke the method before the request. This code will gonna work after java1.4. This method applies for all hosts:
public void fixUntrustCertificate() throws KeyManagementException, NoSuchAlgorithmException{
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
}
};
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
// set the allTrusting verifier
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
}

Last time I checked, Java is not capable of natively doing what you want; you have to use 'work-arounds' to get around such limitations. As far as I see it, interfaces ARE an alternative, but not a good alternative. Perhaps whoever told you that was meaning something like this:
public interface ComponentMethod {
public abstract void PerfromMethod(Container c);
}
public class ChangeColor implements ComponentMethod {
@Override
public void PerfromMethod(Container c) {
// do color change stuff
}
}
public class ChangeSize implements ComponentMethod {
@Override
public void PerfromMethod(Container c) {
// do color change stuff
}
}
public void setAllComponents(Component[] myComponentArray, ComponentMethod myMethod) {
for (Component leaf : myComponentArray) {
if (leaf instanceof Container) { //recursive call if Container
Container node = (Container) leaf;
setAllComponents(node.getComponents(), myMethod);
} //end if node
myMethod.PerfromMethod(leaf);
} //end looping through components
}
Which you'd then invoke with:
setAllComponents(this.getComponents(), new ChangeColor());
setAllComponents(this.getComponents(), new ChangeSize());
The PHP.net recommended way of setting the charset is now this:
The only thing that worked in my case was by using david valentine code. Using Root Attr. in the Person class did not help.
I have this simple Xml:
<?xml version="1.0"?>
<personList>
<Person>
<FirstName>AAAA</FirstName>
<LastName>BBB</LastName>
</Person>
<Person>
<FirstName>CCC</FirstName>
<LastName>DDD</LastName>
</Person>
</personList>

public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
De-Serialization C# code from a Main method:
XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "personList";
xRoot.IsNullable = true;
using (StreamReader reader = new StreamReader(xmlFilePath))

List<Person> result = (List<Person>)(new XmlSerializer(typeof(List<Person>), xRoot)).Deserialize(reader);
int numOfPersons = result.Count;
}
The problem with UTF-8 is that it is not the most space efficient encoding. Also, some random binary byte sequences are invalid UTF-8 encoding. So you can't just interpret a random binary byte sequence as some UTF-8 data because it will be invalid UTF-8 encoding. The benefit of this constrain on the UTF-8 encoding is that it makes it robust and possible to locate multi byte chars start and end whatever byte we start looking at.
As a consequence, if encoding a byte value in the range [0..127] would need only one byte in UTF-8 encoding, encoding a byte value in the range [128..255] would require 2 bytes ! Worse than that. In JSON, control chars, " and \ are not allowed to appear in a string. So the binary data would require some transformation to be properly encoded.
Let see. If we assume uniformly distributed random byte values in our binary data then, on average, half of the bytes would be encoded in one bytes and the other half in two bytes. The UTF-8 encoded binary data would have 150% of the initial size.
Base64 encoding grows only to 133% of the initial size. So Base64 encoding is more efficient.
What about using another Base encoding ? In UTF-8, encoding the 128 ASCII values is the most space efficient. In 8 bits you can store 7 bits. So if we cut the binary data in 7 bit chunks to store them in each byte of an UTF-8 encoded string, the encoded data would grow only to 114% of the initial size. Better than Base64. Unfortunately we can't use this easy trick because JSON doesn't allow some ASCII chars. The 33 control characters of ASCII ( [0..31] and 127) and the " and \ must be excluded. This leaves us only 128-35 = 93 chars.
So in theory we could define a Base93 encoding which would grow the encoded size to 8/log2(93) = 8*log10(2)/log10(93) = 122%. But a Base93 encoding would not be as convenient as a Base64 encoding. Base64 requires to cut the input byte sequence in 6bit chunks for which simple bitwise operation works well. Beside 133% is not much more than 122%.
This is why I came independently to the common conclusion that Base64 is indeed the best choice to encode binary data in JSON. My answer presents a justification for it. I agree it isn't very attractive from the performance point of view, but consider also the benefit of using JSON with it's human readable string representation easy to manipulate in all programming languages.
If performance is critical than a pure binary encoding should be considered as replacement of JSON. But with JSON my conclusion is that Base64 is the best.
In your example propertyInfo.GetValue(this, null)
should work. Consider altering GetNamesAndTypesAndValues()
as follows:
public void GetNamesAndTypesAndValues()
{
foreach (PropertyInfo propertyInfo in allClassProperties)
{
Console.WriteLine("{0} [type = {1}] [value = {2}]",
propertyInfo.Name,
propertyInfo.PropertyType,
propertyInfo.GetValue(this, null));
}
}
I don't know if this is exactly what you want, but did you know you can use the CSS overflow
property to create scrollbars?
CSS:
div.box{
width: 200px;
height: 200px;
overflow: scroll;
}
HTML:
<div class="box">
All your text content...
</div>
I'm unsure of this, so I add it as an answer first.
That means you can call a method either like theobject.themethod()
or by TheClass.themethod(anobject)
.
Edit: Although the difference between methods and functions is small in Python, and non-existant in Python 3, it also doesn't exist in Ruby, simply because Ruby doesn't have functions. When you define functions, you are actually defining methods on Object.
But you still can't take the method of one class and call it as a function, you would have to rebind it to the object you want to call on, which is much more obstuse.
It might just be a connection string error, which is solved by the above process, but if you are using the dll's in multiple projects then making sure the connection string is named properly will fix the error for sure.

This worked for me.
With the Entity Framework most of the time SaveChanges()
is sufficient. This creates a transaction, or enlists in any ambient transaction, and does all the necessary work in that transaction.
Sometimes though the SaveChanges(false) + AcceptAllChanges()
pairing is useful.
The most useful place for this is in situations where you want to do a distributed transaction across two different Contexts.
I.e. something like this (bad):
using (TransactionScope scope = new TransactionScope())
{
//Do something with context1
//Do something with context2
//Save and discard changes
context1.SaveChanges();
//Save and discard changes
context2.SaveChanges();
//if we get here things are looking good.
scope.Complete();
}
If context1.SaveChanges()
succeeds but context2.SaveChanges()
fails the whole distributed transaction is aborted. But unfortunately the Entity Framework has already discarded the changes on context1
, so you can't replay or effectively log the failure.
But if you change your code to look like this:
using (TransactionScope scope = new TransactionScope())
{
//Do something with context1
//Do something with context2
//Save Changes but don't discard yet
context1.SaveChanges(false);
//Save Changes but don't discard yet
context2.SaveChanges(false);
//if we get here things are looking good.
scope.Complete();
context1.AcceptAllChanges();
context2.AcceptAllChanges();
}
While the call to SaveChanges(false)
sends the necessary commands to the database, the context itself is not changed, so you can do it again if necessary, or you can interrogate the ObjectStateManager
if you want.
This means if the transaction actually throws an exception you can compensate, by either re-trying or logging state of each contexts ObjectStateManager
somewhere.
Or in case you just need the value of the first seleted sell (or just one selected cell if one is selected)
TextBox1.Text = SelectedCells[0].Value.ToString();
I implemented this code in JavaScript using the HTML Canvas element, and it produced wonderful simulations at 60 frames per second. I started the simulation off with a collection of a dozen balls at random positions and velocities. I found that at higher velocities, a glancing collision between a small ball and a much larger one caused the small ball to appear to STICK to the edge of the larger ball, and moved up to around 90 degrees around the larger ball before separating. (I wonder if anyone else observed this behavior.)
Some logging of the calculations showed that the Minimum Translation Distance in these cases was not large enough to prevent the same balls from colliding in the very next time step. I did some experimenting and found that I could solve this problem by scaling up the MTD based on the relative velocities:
dot_velocity = ball_1.velocity.dot(ball_2.velocity);
mtd_factor = 1. + 0.5 * Math.abs(dot_velocity * Math.sin(collision_angle));
mtd.multplyScalar(mtd_factor);
I verified that before and after this fix, the total kinetic energy was conserved for every collision. The 0.5 value in the mtd_factor was the approximately the minumum value found to always cause the balls to separate after a collision.
Although this fix introduces a small amount of error in the exact physics of the system, the tradeoff is that now very fast balls can be simulated in a browser without decreasing the time step size.

You have an error in your syntax here:
this._possessions = new Thing[100]();
This doesn't create an "array of things". To create an array of things, you can simply use the array literal expression:
this._possessions = [];
Of the array constructor if you want to set the length:
this._possessions = new Array(100);
I have created a brief working example you can try in the playground.
module Entities {
class Thing {
}
export class Person {
private _name: string;
private _possessions: Thing[];
private _mostPrecious: Thing;
constructor (name: string) {
this._name = name;
this._possessions = [];
this._possessions.push(new Thing())
this._possessions[100] = new Thing();
}
}
}
One more than necessary. I don't mean to be glib, but there are some functions that necessarily need quite a few options. For example:
void *
mmap(void *addr, size_t len, int prot, int flags, int fildes, off_t offset);
There are 6 arguments, and every one of them is essential. Furthermore, there's no common link between them to justify bundling them. Maybe you could define "struct mmapargs", but that would worse.
In order to make it work, you have to set property GroupName of both radio buttons to the same value:
<asp:RadioButton id="rbMetric" runat="server" GroupName="measurementSystem"></asp:RadioButton>
<asp:RadioButton id="rbUS" runat="server" GroupName="measurementSystem"></asp:RadioButton>
Personally, I prefer to use a RadioButtonList:
<asp:RadioButtonList ID="rblMeasurementSystem" runat="server">
<asp:ListItem Text="Metric" Value="metric" />
<asp:ListItem Text="US" Value="us" />
</asp:RadioButtonList>
To uninstall anaconda you have to:
1) Remove the entire anaconda install directory with:
rm -rf ~/anaconda2
2) And (OPTIONAL):
->Edit ~/.bash_profile to remove the anaconda directory from your PATH environment variable.
->Remove the following hidden file and folders that may have been created in the home directory:
rm -rf ~/.condarc ~/.conda ~/.continuum
First Method
- (void)didMoveToParentViewController:(UIViewController *)parent
{
if (![parent isEqual:self.parentViewController]) {
NSLog(@"Back pressed");
}
}
Second Method
-(void) viewWillDisappear:(BOOL)animated {
if ([self.navigationController.viewControllers indexOfObject:self]==NSNotFound) {
// back button was pressed. We know this is true because self is no longer
// in the navigation stack.
}
[super viewWillDisappear:animated];
}
Remove "track by index" from the ng-repeat and it would refresh the DOM
One big advantage of MATLAB over R is the quality of MATLAB documentation. R, being open source, suffers in this respect, a feature common to many open source projects.
R is, however, a very useful environment and language. It is widely used in the bioinformatics community and has many packages useful in this domain.
An alternative to R is Octave (http://www.gnu.org/software/octave/) which is very similar to MATLAB, it can run MATLAB scripts.
I faced a similar issue and this is how I fixed it,
The problem is due to the conversion process from JSON to Java, one need to have the right run time jackson libraries for the conversion to happen correctly.
Add the following jars (through dependency or by downloading and adding to the classpath.

</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.5.3</version>
</dependency>
This should fix the problem.

Basically, the term "x-bit machine" does not depend on your machine. That is why we do not need to change our processors or other hardware in order to migrate from a 32bit system to a 64bit one (or vice versa).
32bit and 64bit stands for the addressing capability of the OS running on your machine.
However, it still does not mean that a x-bit operating system is capable to address 2^x GB memory. Because the 'B' in "GB" means "byte" and not "bit". 1 byte equals 8 bits.
Actually a 32bit system can not even address 2^32/8 = 2^29 GB memory space while there should some memory be reserved to the OS.
It is something just below 3 GB.
In addition to all the people pointing out that +
is overloaded for Strings, -
is also overloaded for both floating point and integer operations, as are *
and /
.
[edit]
%
is also overloaded for floating point, which can be a bit of a surprise for those with a C or C++ background.
I encountered this running a brand new project. Neither the Allow or Always Allow button seemed to work, however it wasn't giving me the 'incorrect password' shaking feedback. What was happening was that there were multiple dialog boxes all in the same position, so as I entered a password and clicked Allow nothing changed visually. I ended up having at least 3 dialogs all stacked up on each other, which I only discovered when I tried dragging the dialog. Entering passwords into each of them let my project finish building.
I would suggest a very simple solution.
Take the View reference variable and set view in OnCreateView. Check if view already exists in this variable, then return same view.
private View fragmentView;
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
if (fragmentView != null) {
return fragmentView;
}
View view = inflater.inflate(R.layout.yourfragment, container, false);
fragmentView = view;
return view;
}
I'm not really sure, but you can try some like this:
var pack = function( arr ) {
var length = arr.length,
result = {},
i;
for ( i = 0; i < length; i++ ) {
result[ ( i < 10 ? '0' : '' ) + ( i + 1 ) ] = arr[ i ];
}
return result;
};
pack( [ 'one', 'two', 'three' ] ); //{01: "one", 02: "two", 03: "three"}
the Best of both worlds.....

readonly="readonly"
is xhtml syntax. In xhtml boolean attributes are written this way. In xhtml 'attribute minimization' (<input type="checkbox" checked>
) isn't allowed, so this is the valid way to include boolean attributes in xhtml. See this page for more.information.
If your document type is xhtml transitional or strict and you want to validate it, use readonly="readonly
otherwise readonly
is sufficient.

Building on Rene's answer, you could also write a function that returned either TRUE if the substring was present, or FALSE if it wasn't:
Public Function Contains(strBaseString As String, strSearchTerm As String) As Boolean
'Purpose: Returns TRUE if one string exists within another
On Error GoTo ErrorMessage
Contains = InStr(strBaseString, strSearchTerm)
Exit Function
ErrorMessage:

next() and nextLine() methods are associated with Scanner and is used for getting String inputs. Their differences are...
next() can read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same line after reading the input.
nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.
Read article :Difference between next() and nextLine()
Replace your while loop with :
while(r.hasNext()) {
scan = r.next();
System.out.println(scan);
if(scan.length()==0) {continue;}
//treatment
}
Using hasNext()
and next()
methods will resolve the issue.

"1=This is something, 2=This is something,,with an escaped comma, 3=This is something else"
I think this is an elegant solution, with a trick that avoids a lot of regex complexity:
if (string.IsNullOrEmpty(encodedValues))
{
return null;
}
else
{
var retVal = new Dictionary<int, string>();
var reFields = new Regex(@"([0-9]+)\=(([A-Za-z0-9\s]|(,,))+),");
foreach (Match match in reFields.Matches(encodedValues + ","))
{
var id = match.Groups[1].Value;
var value = match.Groups[2].Value;
retVal[int.Parse(id)] = value.Replace(",,", ",");
}
return retVal;
}
I think it can be adapted to the original question with an expression like @"([0-9]+),\s?"
and parse on Groups[0]
.
I hope it's helpful to somebody and thanks for the tips on getting it close to there, especially Asaph!
In your action change ViewBag.countrydrop = item8
to ViewBag.country = item8;
and in View write like this:
@Html.DropDownList("country",
(IEnumerable<SelectListItem>)ViewBag.country,
"Select country")
Actually when you write
@Html.DropDownList("country", (IEnumerable)ViewBag.country, "Select country")
or
Html.DropDownList("country","Select Country)
it looks in for IEnumerable<SelectListItem>
in ViewBag
with key country, you can also use this overload in this case:
@Html.DropDownList("country","Select country") // it will look for ViewBag.country and populates dropdown
The query can be written slightly simpler, like this:
DECLARE @T INT = 2
SELECT CASE
WHEN @T < 1 THEN 'less than one'
WHEN @T = 1 THEN 'one'
ELSE 'greater than one'
END T
You said you didn't want to do this in AJAX. While AJAX is great for this, there is a way to show one DIV while waiting for the entire <body>
to load. It goes something like this:
<html>
<head>
<style media="screen" type="text/css">
.layer1_class { position: absolute; z-index: 1; top: 100px; left: 0px; visibility: visible; }
.layer2_class { position: absolute; z-index: 2; top: 10px; left: 10px; visibility: hidden }
</style>
<script>
function downLoad(){
if (document.all){
document.all["layer1"].style.visibility="hidden";
document.all["layer2"].style.visibility="visible";
} else if (document.getElementById){
node = document.getElementById("layer1").style.visibility='hidden';
node = document.getElementById("layer2").style.visibility='visible';
}
}
</script>
</head>
<body onload="downLoad()">
<div id="layer1" class="layer1_class">
<table width="100%">
<tr>
<td align="center"><strong><em>Please wait while this page is loading...</em></strong></p></td>
</tr>
</table>
</div>
<div id="layer2" class="layer2_class">
<script type="text/javascript">
alert('Just holding things up here. While you are reading this, the body of the page is not loading and the onload event is being delayed');
</script>
Final content.
</div>
</body>
</html>
The onload event won't fire until all of the page has loaded. So the layer2 <DIV>
won't be displayed until the page has finished loading, after which onload will fire.
Regarding python2 (and python2 only), some of the former answers rely on using the following hack:
import sys
reload(sys) # Reload is a hack
sys.setdefaultencoding('UTF8')
It is discouraged to use it (check this or this)
In my case, it come with a side-effect: I'm using ipython notebooks, and once I run the code the ´print´ function no longer works. I guess there would be solution to it, but still I think using the hack should not be the correct option.
After trying many options, the one that worked for me was using the same code in the sitecustomize.py
, where that piece of code is meant to be. After evaluating that module, the setdefaultencoding function is removed from sys.
So the solution is to append to file /usr/lib/python2.7/sitecustomize.py
the code:
import sys
sys.setdefaultencoding('UTF8')
When I use virtualenvwrapper the file I edit is ~/.virtualenvs/venv-name/lib/python2.7/sitecustomize.py
.
And when I use with python notebooks and conda, it is ~/anaconda2/lib/python2.7/sitecustomize.py
This will get you the timezone as a PHP variable. I wrote a function using jQuery and PHP. This is tested, and does work!
On the PHP page where you are want to have the timezone as a variable, have this snippet of code somewhere near the top of the page:
<?php
session_start();
$timezone = $_SESSION['time'];
?>
This will read the session variable "time", which we are now about to create.
On the same page, in the <head>
section, first of all you need to include jQuery:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
Also in the <head>
section, paste this jQuery:
<script type="text/javascript">
$(document).ready(function() {
if("<?php echo $timezone; ?>".length==0){
var visitortime = new Date();
var visitortimezone = "GMT " + -visitortime.getTimezoneOffset()/60;
$.ajax({
type: "GET",
url: "http://example.com/timezone.php",
data: 'time='+ visitortimezone,
success: function(){
location.reload();
}
});
}
});
</script>
You may or may not have noticed, but you need to change the url to your actual domain.
One last thing. You are probably wondering what the heck timezone.php is. Well, it is simply this: (create a new file called timezone.php and point to it with the above url)
<?php
session_start();
$_SESSION['time'] = $_GET['time'];
?>
If this works correctly, it will first load the page, execute the JavaScript, and reload the page. You will then be able to read the $timezone variable and use it to your pleasure! It returns the current UTC/GMT time zone offset (GMT -7) or whatever timezone you are in.
You can read more about this on my blog
To put text, use .text('text')
If you want to use .html(SomeValue)
, SomeValue should have html tags that can be inside a div it must work too.
Just check your script location, as farzad said.
Using Django's session framework should cover most scenarios, but Django also now provide direct cookie manipulation methods on the request and response objects (so you don't need a helper function).
Setting a cookie:
def view(request):
response = HttpResponse('blah')
response.set_cookie('cookie_name', 'cookie_value')
Retrieving a cookie:
def view(request):
value = request.COOKIES.get('cookie_name')
if value is None:
# Cookie is not set
# OR
try:
value = request.COOKIES['cookie_name']
except KeyError:
# Cookie is not set
In Java 9, you can now use Matcher#results()
to get a Stream<MatchResult>
which you can use to get a list/array of matches.
import java.util.regex.Pattern;
import java.util.regex.MatchResult;
String[] matches = Pattern.compile("your regex here")
.matcher("string to search from here")
.results()
.map(MatchResult::group)
.toArray(String[]::new);
// or .collect(Collectors.toList())
Sometimes you still need to use FirstOrDefault if you have to do different tests. If the Key component of your dictionnary is nullable, you can do this:
thisTag = _tags.FirstOrDefault(t => t.Key.SubString(1,1) == 'a');
if(thisTag.Key != null) { ... }
Using FirstOrDefault, the returned KeyValuePair's key and value will both be null if no match is found.
Look carefully at your includes - perhaps you have a blank line after a closing ?> ?
This will cause some literal whitespace to be sent as output, preventing you from making subsequent header calls.
Note that it is legal to leave the close ?> off the include file, which is a useful idiom for avoiding this problem.
(EDIT: looking at your header, you need to avoid doing any HTML output if you want to output headers, or use output buffering to capture it).
Finally, as the PHP manual page for header points out, you should really use full URLs to redirect:
Note: HTTP/1.1 requires an absolute URI as argument to Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:
The general idea is to add, commit and push your files to the GitHub repo.
First you need to clone your GitHub repo.
Then, you would git add all the files from your other folder: one trick is to specify an alternate working tree when git add'ing your files.
git --work-tree=yourSrcFolder add .
(done from the root directory of your cloned Git repo, then git commit -m "a msg"
, and git push origin master
)
That way, you keep separate your initial source folder, from your Git working tree.
Note that since early December 2012, you can create new files directly from GitHub:
ProTip™: You can pre-fill the filename field using just the URL.
Typing?filename=yournewfile.txt
at the end of the URL will pre-fill the filename field with the nameyournewfile.txt
.
I was using spring-web version 4.3.7
Changing it to a working 4.1.7 immediately solved it.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
Use the options
command, e.g. options(max.print=1000000)
.
See ?options
:
‘max.print’: integer, defaulting to ‘99999’. ‘print’ or ‘show’
methods can make use of this option, to limit the amount of
information that is printed, to something in the order of
(and typically slightly less than) ‘max.print’ _entries_.
Use
label.setOpaque(true);
Otherwise the background is not painted, since the default of opaque
is false
for JLabel
.
From the JavaDocs:
If true the component paints every pixel within its bounds. Otherwise, the component may not paint some or all of its pixels, allowing the underlying pixels to show through.
For more information, read the Java Tutorial How to Use Labels.
DependencyObject GetTopParent(DependencyObject current)

The context parameter just sets the value of this
in the iterator function.
var someOtherArray = ["name","patrick","d","w"];
_.each([1, 2, 3], function(num) {
// In here, "this" refers to the same Array as "someOtherArray"
alert( this[num] ); // num is the value from the array being iterated
// so this[num] gets the item at the "num" index of
// someOtherArray.
}, someOtherArray);
Working Example: http://jsfiddle.net/a6Rx4/
It uses the number from each member of the Array being iterated to get the item at that index of someOtherArray
, which is represented by this
since we passed it as the context parameter.
If you do not set the context, then this
will refer to the window
object.
This is probably desirable for backwards compatibility.
Python3 breaks backwards compatibility, and programs invoking 'python' probably expect python2. You probably have many programs and scripts which you are not even aware of which expect python=python2, and changing this would break those programs and scripts.
The answer you are probably looking for is You should not change this.
You could, however, make a custom alias in your shell. The way you do so depends on the shell, but perhaps you could do alias py=python3
If you are confused about how to start the latest version of python, it is at least the case on Linux that python3
leaves your python2
installation intact (due to the above compatibility reasons); thus you can start python3 with the python3
command.
One issue that can occur, and seemingly break this is when using auto minimization of css. The request path for the minified bundle can have a different path than the original css. This may happen automatically so it can cause confusion.
The mapped request path for the minified bundle should be "/originalcssfolder/minifiedbundlename" not just "minifiedbundlename".
In other words, name your bundles to have same path (with the /) as the original folder structure, this way any external resources like fonts, images will map to correct URIs by the browser. The alternative is to use absolute url( refs in your css but that isn't usually desirable.
Yes, you could append ;Connection Timeout=30
to your connection string and specify the value you wish.
The timeout value set in the Connection Timeout
property is a time expressed in seconds. If this property isn't set, the timeout value for the connection is the default value (15 seconds).
Moreover, setting the timeout value to 0
, you are specifying that your attempt to connect waits an infinite time. As described in the documentation, this is something that you shouldn't set in your connection string:
A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect waits indefinitely.
Just to expand on previous answers, a function to do this could work like this (changing the time and interval formats however you like them according to this for function.date, and this for DateInterval):
// Return adjusted start and end times as an array.
function expandTimeByMinutes( $time, $beforeMinutes, $afterMinutes ) {
$time = DateTime::createFromFormat( 'H:i', $time );
$time->sub( new DateInterval( 'PT' . ( (integer) $beforeMinutes ) . 'M' ) );
$startTime = $time->format( 'H:i' );
$time->add( new DateInterval( 'PT' . ( (integer) $beforeMinutes + (integer) $afterMinutes ) . 'M' ) );
$endTime = $time->format( 'H:i' );
return [
'startTime' => $startTime,
'endTime' => $endTime,
];
}
$adjustedStartEndTime = expandTimeByMinutes( '10:00', 30, 30 );
echo '<h1>Adjusted Start Time: ' . $adjustedStartEndTime['startTime'] . '</h1>' . PHP_EOL . PHP_EOL;
echo '<h1>Adjusted End Time: ' . $adjustedStartEndTime['endTime'] . '</h1>' . PHP_EOL . PHP_EOL;
<form id = "uploadForm" name = "uploadForm" enctype="multipart/form-data">

$('#uploadFile').change(function(){
var fileName = this.files[0].name;
var fileSize = this.files[0].size;
var fileType = this.files[0].type;
alert('FileName : ' + fileName + '\nFileSize : ' + fileSize + ' bytes');
});
</script>
Note: To get the uploading file name means then use jquery val() method.
For Ex:
var fileName = $('#uploadFile').val();
I checked this above code before post, it works perfectly.!
Use MySQL's STR_TO_DATE()
function to parse the string that you're attempting to insert:
INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
(STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))
In my case I misspelled the name of the branch. Locally I did something like:
git push --set-upstream origin feture/my-feature
where my branch name was missing the a
in feature
. I corrected it to:
git push --set-upstream origin feature/my-feature
And everything worked fine.
One recursive for the fun.
Not the most elegant answer, but should work everywhere:
import os
def split_path(path):
head = os.path.dirname(path)
tail = os.path.basename(path)
if head == os.path.dirname(head):
return [tail]
return split_path(head) + [tail]
By default, it's not in your PATH. You need to use the "Visual Studio 2005 Command Prompt". Alternatively, you can run the vsvars32 batch file, which will set up your environment correctly.
Conveniently, the path to this is stored in the VS80COMNTOOLS environment variable.

If you download Bootstrap without the "Print media styles" option, you will not have this problem and do not have to remove the "@media print" code manually in your bootstrap.css file.
I find that the quickest (but somewhat dirty) way to do this is by invoking objc_msgSend directly. However, it's dangerous to invoke it directly because you need to read the documentation and make sure that you're using the correct variant for the type of return value and because objc_msgSend is defined as vararg for compiler convenience but is actually implemented as fast assembly glue. Here's some code used to call a delegate method -[delegate integerDidChange:] that takes a single integer argument.
#import <objc/message.h>
SEL theSelector = @selector(integerDidChange:);
if ([self.delegate respondsToSelector:theSelector])
{
typedef void (*IntegerDidChangeFuncPtrType)(id, SEL, NSInteger);
IntegerDidChangeFuncPtrType MyFunction = (IntegerDidChangeFuncPtrType)objc_msgSend;
MyFunction(self.delegate, theSelector, theIntegerThatChanged);
}
This first saves the selector since we're going to refer to it multiple times and it would be easy to create a typo. It then verifies that the delegate actually responds to the selector - it might be an optional protocol. It then creates a function pointer type that specifies the actual signature of the selector. Keep in mind that all Objective-C messages have two hidden first arguments, the object being messaged and the selector being sent. Then we create a function pointer of the appropriate type and set it to point to the underlying objc_msgSend function. Keep in mind that if the return value is a float or struct, you need to use a different variant of objc_msgSend. Finally, send the message using the same machinery that Objective-C uses under the sheets.
This answer is based on the answer from Zorawar, but I couldn't leave a comment there.
You can make the auto
(C++11)/typedef
version const
by using cbegin
and cend
instead
for (auto i = path.cbegin(); i != path.cend(); ++i)
std::cout << *i << ' ';
Here's another:
data[data$Code == "A" | data$Code == "B", ]
It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,
data[Code == "A" | Code == "B", ]
also works, which is one of the really useful things about R.
In some sort of main or first loading CSS file, just do:
@import url('https://fonts.googleapis.com/css?family=Source+Sans+Pro:regular,bold,italic&subset=latin,latin-ext');
You don't need to wrap in any sort of @font-face, etc. the response you get back from Google's API is ready to go and lets you use font families like normal.
Then in your main React app JavaScript, at the top put something like:
import './assets/css/fonts.css';
What I did actually was made an app.css
that imported a fonts.css
with a few font imports. Simply for organization (now I know where all my fonts are). The important thing to remember is that you import the fonts first.
Keep in mind that any component you import to your React app should be imported after the style import. Especially if those components also import their own styles. This way you can be sure of the ordering of styles. This is why it's best to import fonts at the top of your main file (don't forget to check your final bundled CSS file to double check if you're having trouble).
There's a few options you can pass the Google Font API to be more efficient when loading fonts, etc. See official documentation: Get Started with the Google Fonts API
Edit, note: If you are dealing with an "offline" application, then you may indeed need to download the fonts and load through Webpack.
The first method is right.
The second method kills kittens if you attempt to do anything with x
after the fact other than Object
methods.

isset() tests if a variable is set and not null:
http://us.php.net/manual/en/function.isset.php
empty() can return true when the variable is set to certain values:
http://us.php.net/manual/en/function.empty.php
<?php
$the_var = 0;
if (isset($the_var)) {
echo "set";
} else {
echo "not set";
}

echo "empty";
} else {
echo "not empty";
}
?>
I found using css opacity is better for a simple show/hide hover, and you can add css3 transitions to make a nice finished hover effect. The transitions will just be dropped by older IE browsers, so it degrades gracefully to.
#stuff {
opacity: 0.0;
-webkit-transition: all 500ms ease-in-out;
-moz-transition: all 500ms ease-in-out;
-ms-transition: all 500ms ease-in-out;
-o-transition: all 500ms ease-in-out;
transition: all 500ms ease-in-out;
}
#hover {
width:80px;
height:20px;
background-color:green;
margin-bottom:15px;
}
#hover:hover + #stuff {
opacity: 1.0;
}
<div id="hover">Hover</div>
<div id="stuff">stuff</div>
For the Single line and double line break here are the following codes.

xDoc.LoadXML("<head><body><Inner> welcome </head> </Inner> <Outer> Bye</Outer>

A simple solution would be to just write
this.date = new Date().toLocaleDateString();
date .toLocaleDateString()
time .toLocaleTimeString()
both .toLocaleString()
Hope this helps.

Explanation from the bottom for ones who came here without any knowledge of branches.
Basic master branch development logic is: You work only on another branches and use master only to merge another branches.
You begin to create a new branch in this way:
$ cd /var/www
$ git clone [email protected]:user_name/repository_name.git
$ git branch new_branch
$ git checkout new_branch
$ git add .
$ git commit -m “Initial commit”
$ git push # pushes commits only to “new_branch”
$ git merge master
$ git checkout master # goes to master branch
$ git merge development # merges files in localhost. Master shouldn’t have any commits ahead, otherwise there will be a need for pull and merging code by hands!
$ git push # pushes all “new_branch” commits to both branches - “master” and “new_branch”
I also recommend using the Sourcetree App to see visual tree of changes and branches.
<android.support.v7.widget.AppCompatButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"

This one should work
<button [ngClass]="{[namespace + '-mybutton']: type === 'mybutton'}"></button>
but Angular throws on this syntax. I'd consider this a bug. See also https://stackoverflow.com/a/36024066/217408
The others are invalid. You can't use []
together with {{}}
. Either one or the other. {{}}
binds the result stringified which doesn't lead to the desired result in this case because an object needs to be passed to ngClass
.
As workaround the syntax shown by @A_Sing or
<button [ngClass]="type === 'mybutton' ? namespace + '-mybutton' : ''"></button>
can be used.
/* you can match the exact string with table value*/
if(md5("string to match") == $res["hashstring"])
echo "login correct";
Your first formulation, image_url('logo.png')
, is correct. If the image is found, it will generate the path /assets/logo.png
(plus a hash in production). However, if Rails cannot find the image that you named, it will fall back to /images/logo.png
.
The next question is: why isn't Rails finding your image? If you put it in app/assets/images/logo.png, then you should be able to access it by going to http://localhost:3000/assets/logo.png
.
If that works, but your CSS isn't updating, you may need to clear the cache. Delete tmp/cache/assets
from your project directory and restart the server (webrick, etc.).
If that fails, you can also try just using background-image: url(logo.png);
That will cause your CSS to look for files with the same relative path (which in this case is /assets).
The complete solution I found that worked was:
@echo off
cd /D "%~dp0"
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)
"Put your command here"

If you are using MySQL, you can use order by FIELD(id, ...)
approach:
Company.findAll({
where: {id : {$in : companyIds}},
order: sequelize.literal("FIELD(company.id,"+companyIds.join(',')+")")
})
Keep in mind, it might be slow. But should be faster, than manual sorting with JS.
As of 2018, there is also iText7 (A next iteration of old iTextSharp library) and its HTML to PDF package available: itext7.pdfhtml
Usage is straightforward:
HtmlConverter.ConvertToPdf(
new FileInfo(@"Path\to\Html\File.html"),
new FileInfo(@"Path\to\Pdf\File.pdf")
);
Method has many more overloads.
Update: iText* family of products has dual licensing model: free for open source, paid for commercial use.
If you'd like to turn this on by default for ALL ObjectMapper instances in a process, here's a little hack that will set the default value of INDENT_OUTPUT to true:
val indentOutput = SerializationFeature.INDENT_OUTPUT
val defaultStateField = indentOutput.getClass.getDeclaredField("_defaultState")
defaultStateField.setAccessible(true)
defaultStateField.set(indentOutput, true)
In the v-model the value of the property might not be a strict boolean value and the checkbox might not 'recognise' the value as checked/unchecked. There is a neat feature in VueJS to make the conversion to true or false:
<input
type="checkbox"
v-model="toggle"
true-value="yes"
false-value="no"

I'm also having the exact same problem with both /usr/local/bin and /etc/sudoers on OSX Snow lepard.Even when i logged in as admin and tried to change the permissions via the terminal, it still says "Operation not permitted". And i did the following to get the permission of these folders.
From the terminal, I accessed /etc/sudoers file and using pico editor i added the following code: username ALL=(ALL) ALL Replace "username" with your MAC OS account name
The port number is an unsigned 16-bit integer, so 65535.

I had the same problem in my newly started project with minimum api 23, and finally i have added these lines of codes in my gradle dependency file and it solved the error:)

You can't do what you're asking natively with an array, but javascript objects are hashes, so you can say...
var hash = {};
hash['k1'] = 'abc';
...
Then you can retrieve using bracket or dot notation:
alert(hash['k1']); // alerts 'abc'
alert(hash.k1); // also alerts 'abc'
For arrays, check the underscore.js library in general and the detect method in particular. Using detect you could do something like...
_.detect(arr, function(x) { return x.name == 'k1' });
Or more generally
MyCollection = function() {
this.arr = [];
}
MyCollection.prototype.getByName = function(name) {
return _.detect(this.arr, function(x) { return x.name == name });
}
MyCollection.prototype.push = function(item) {
this.arr.push(item);
}
etc...
You could do the following:
var inputType = $('#inputid').attr('type');
Here's one way:
CString str;
str.Format("%d", 5);
In your case, try _T("%d")
or L"%d"
rather than "%d"
If you're using VSCode, then you're in luck. Select the range that you want to stage, then use Git: Stage Selected Ranges
to stage them, and commit if you want.
I recorded a gif to demonstrate what I meant:
Convert it back to datetime after converting to date in order to keep same datatime if needed
select Convert(datetime, Convert(date, getdate()) )
You can use sp_lock
(and sp_lock2
), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks
:
select
object_name(p.object_id) as TableName,
resource_type, resource_description
from
sys.dm_tran_locks l
join sys.partitions p on l.resource_associated_entity_id = p.hobt_id

}
}
Assuming the title of your question is correct and you want the time:

This code copies all stored procedures in the Master database to the target database, you can copy just the procedures you like by filtering the query on procedure name.

Did have identical problem with on XP machine when installing javacv
and opencv
in combination with Eclipse. It turned out that I was missing the following files:
Once these were installed, the project compiled and ran OK.
The following regex will accept YYYY-MM-DD (within the range 1600-2999 year) formatted dates taking into consideration leap years:
^((?:(?:1[6-9]|2[0-9])\d{2})(-)(?:(?:(?:0[13578]|1[02])(-)31)|((0[1,3-9]|1[0-2])(-)(29|30))))$|^(?:(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(-)02(-)29)$|^(?:(?:1[6-9]|2[0-9])\d{2})(-)(?:(?:0[1-9])|(?:1[0-2]))(-)(?:0[1-9]|1\d|2[0-8])$
Examples:
You can test it here.
Note: if you want to accept one digit as month or day you can use:
^((?:(?:1[6-9]|2[0-9])\d{2})(-)(?:(?:(?:0?[13578]|1[02])(-)31)|((0?[1,3-9]|1[0-2])(-)(29|30))))$|^(?:(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(-)0?2(-)29)$|^(?:(?:1[6-9]|2[0-9])\d{2})(-)(?:(?:0?[1-9])|(?:1[0-2]))(-)(?:0?[1-9]|1\d|2[0-8])$
I have created the above regex starting from this solution
First thing there is no need of having two different versions of jquery libraries in one page,either "1.9.1" or "2.0.0" is sufficient to make ajax calls work..
Here is your controller code:
public ActionResult Index()
{
return View();
}
public ActionResult FirstAjax(string a)
{
return Json("chamara", JsonRequestBehavior.AllowGet);
}
This is how your view should look like:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var a = "Test";
$.ajax({
url: "../../Home/FirstAjax",
type: "GET",
data: { a : a },
success: function (response) {
alert(response);
},
error: function (response) {
alert(response);
}
});
});
</script>
The working version of your code (from the errors pointed out by BoltClock):
<?php
$date = '2011-01-01';
$timestamp = strtotime($date);
$weekday= date("l", $timestamp );
$normalized_weekday = strtolower($weekday);
echo $normalized_weekday ;
if (($normalized_weekday == "saturday") || ($normalized_weekday == "sunday")) {
echo "true";
} else {
echo "false";
}
?>
The stray "{" is difficult to see, especially without a decent PHP editor (in my case). So I post the corrected version here.

Old post but I go this error when trying to convert from website project to web application project.
Follow the instructions on this Link. I still got the global.asax error but all I did was delete it and re-add it back by right clicking on the project in visual studio and selecting add new item. Add the global.asax file and it worked.
You can do this without moment.js
A way to do this in native Javascript code :
var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);
firstDay = moment(firstDay).format(yourFormat);
lastDay = moment(lastDay).format(yourFormat);
Use "\t". That's the tab space character.
You can find a list of many of the Java escape characters here: http://java.sun.com/docs/books/tutorial/java/data/characters.html
The reasons for warning are documented here, and the simple fixes are to turn off the warning or put the following declaration in your code to supply the version UID. The actual value is not relevant, start with 999 if you like, but changing it when you make incompatible changes to the class is.
public class HelloWorldSwing extends JFrame {
JTextArea m_resultArea = new JTextArea(6, 30);
private static final long serialVersionUID = 1L;
You can still use installutil without visual studio, it is included with the .net framework
On your server, open a command prompt as administrator then:
CD C:\Windows\Microsoft.NET\Framework\v4.0.version (insert your version)
installutil "C:\Program Files\YourWindowsService\YourWindowsService.exe" (insert your service name/location)
To uninstall:
installutil /u "C:\Program Files\YourWindowsService\YourWindowsService.exe" (insert your service name/location)
tr:hover td {background-color:#000;}
You need to use delimiters with regexes in PHP. You can use the often used /
, but PHP lets you use any matching characters, so @
and #
are popular.
If you are interpolating variables inside your regex, be sure to pass the delimiter you chose as the second argument to preg_quote()
.
We can use assert
here.
def _input(inp_str:str):
try:
assert len(inp_str)<=15,print('More than 15 characters present')
assert all('a'<=i<='z' for i in inp_str),print('Characters other than "a"-"z" are found')
return inp_str
except Exception as e:
pass
_input('abcd')
#abcd
_input('abc d')
#Characters other than "a"-"z" are found
_input('abcdefghijklmnopqrst')
#More than 15 characters present
Login to virtual machine use below command to check ip address. (anyone will work)
If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1
If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine
Here is a single-liner of how you can delete ALL browser network cache using Cache.delete()
caches.keys().then((keyList) => Promise.all(keyList.map((key) => caches.delete(key))))
Works on Chrome 40+, Firefox 39+, Opera 27+ and Edge.
Many people will suggest you use MERGE
, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:
http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/
Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;
A lot of folks will suggest this way:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
UPDATE ...
END
ELSE
BEGIN
INSERT ...
END
COMMIT TRANSACTION;
But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)
Others will suggest this way:
BEGIN TRY
INSERT ...
END TRY
BEGIN CATCH
IF ERROR_NUMBER() = 2627
UPDATE ...
END CATCH
However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:
Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE
is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.
FYI: In order for @Vadim's answer to work with a manual unwind seque action called from within a View Controller you must place the command:
[self performSegueWithIdentifier:(NSString*) identifier sender:(id) sender];
inside of the overriden class method viewDidAppear like so:
-(void) viewDidAppear:(BOOL) animated
{
[super viewDidAppear: animated];
[self performSegueWithIdentifier:@"SomeSegueIdentifier" sender:self];
}
If you put it in other ViewController methods like viewDidLoad or viewWillAppear it will be ignored.
Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.
I just tested (should have done that first), and something like ng-show="!a && b"
worked as expected.

Basically, he implemented this function:
function toDataUrl(url, callback) {
var xhr = new XMLHttpRequest();
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function() {
callback(reader.result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', url);
xhr.responseType = 'blob';
xhr.send();
}
And in your case, you can use it like this:
toDataUrl(imagepath, function(myBase64) {
console.log(myBase64); // myBase64 is the base64 string
});
I found this scriplet in a script that deletes all files older than 14 days:
CNT=0
for i in $(find -type f -ctime +14); do
((CNT = CNT + 1))
echo -n "." >> $PROGRESS
rm -f $i
done
echo deleted $CNT files, done at $(date "+%H:%M:%S") >> $LOG
I think a little additional "man find" and looking for the -ctime / -atime etc. parameters will help you here.

@AnsgarWiechers - it's not my experience that querying everything and then pruning the result is more efficient when you're doing a targeted search of known accounts. Although, yes, it is also more efficient to select just the properties you need to return.
The below examples are based on a domain in the range of 20,000 account objects.
measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st }
...
Seconds : 16
Milliseconds : 208
measure-command {$userlist | get-aduser -Properties DisplayName,st}
...
Seconds : 3
Milliseconds : 496
In the second example, $userlist contains 368 account names (just strings, not pre-fetched account objects).
Note that if I include the where
clause per your suggestion to prune to the actually desired results, it's even more expensive.
measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st |where {$userlist -Contains $_.samaccountname } }
...
Seconds : 17
Milliseconds : 876
Indexed attributes seem to have similar performance (I tried just returning displayName
).
Even if I return all user account properties in my set, it's more efficient. (Adding a select statement to the below brings it down by a half-second).
measure-command {$userlist | get-aduser -Properties *}
...
Seconds : 12
Milliseconds : 75
I can't find a good document that was written in ye olde days about AD queries to link to, but you're hitting every account in your search scope to return the properties. This discusses the basics of doing effective AD queries - scoping and filtering: https://msdn.microsoft.com/en-us/library/ms808539.aspx#efficientadapps_topic01
When your search scope is "*", you're still building a (big) list of the objects and iterating through each one. An LDAP search filter is always more efficient to build the list first (or a narrow search base, which is again building a smaller list to query).
This might help you - 1) Open a file of your package. 2) Android Studio displays the breadcrumbs of the file, above the opened file. On the package you want renamed: Right click > Refactor > Rename.

It appears adding LogicalName to the project file fixes it:
<LogicalName>$(RootNamespace).Properties.Resources.resources</LogicalName>
i.e. so the embedded resource entry in the project file looks like this:
<ItemGroup>
<EmbeddedResource Include="Properties\Resources.resx">
<Generator>ResXFileCodeGenerator</Generator>
<LastGenOutput>Resources.Designer.cs</LastGenOutput>
<LogicalName>$(RootNamespace).Properties.Resources.resources</LogicalName>
</EmbeddedResource>
</ItemGroup>
This is detailed in: http://blogs.msdn.com/b/msbuild/archive/2007/10/19/manifest-resource-names-changed-for-resources-files.aspx
Note that we are using a .resx file, but the bug still appears to occur.
Update: The problem with resources (incl. XAML) appears to be related to output paths and the use of forward or backward slashes as detailed in: Why does modifying project output directories cause: IOException was unhandled "Cannot locate resource 'app.xaml'."

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<iframe src="...">

After reading all the solutions posted here. This is how I solved it:
// How to embedded a "Text file" inside of a C# project
// and read it as a resource from c# code:
//
// (1) Add Text File to Project. example: 'myfile.txt'
//
// (2) Change Text File Properties:
// Build-action: EmbeddedResource
// Logical-name: myfile.txt
// (note only 1 dot permitted in filename)
//
// (3) from c# get the string for the entire embedded file as follows:
//
// string myfile = GetEmbeddedResourceFile("myfile.txt");
public static string GetEmbeddedResourceFile(string filename) {
var a = System.Reflection.Assembly.GetExecutingAssembly();
using (var s = a.GetManifestResourceStream(filename))
using (var r = new System.IO.StreamReader(s))
{
string result = r.ReadToEnd();
return result;
}
return "";
}
var returnUrl = string.IsNullOrEmpty(Context.Request.Path) ? "~/" : $"~{Context.Request.Path.Value}{Context.Request.QueryString}";
If you only want to allow specific characters, you could also do it like this:
function randomString(length, chars) {
var result = '';
for (var i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
return result;
}
var rString = randomString(32, '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ');
Here's a jsfiddle to demonstrate: http://jsfiddle.net/wSQBx/
Another way to do it could be to use a special string that tells the function what types of characters to use. You could do that like this:
function randomString(length, chars) {
var mask = '';
if (chars.indexOf('a') > -1) mask += 'abcdefghijklmnopqrstuvwxyz';
if (chars.indexOf('A') > -1) mask += 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
if (chars.indexOf('#') > -1) mask += '0123456789';
if (chars.indexOf('!') > -1) mask += '~`!@#$%^&*()_+-={}[]:";\'<>?,./|\\';
var result = '';
for (var i = length; i > 0; --i) result += mask[Math.floor(Math.random() * mask.length)];
return result;
}
console.log(randomString(16, 'aA'));
console.log(randomString(32, '#aA'));
console.log(randomString(64, '#A!'));
Fiddle: http://jsfiddle.net/wSQBx/2/
Alternatively, to use the base36 method as described below you could do something like this:
function randomString(length) {
return Math.round((Math.pow(36, length + 1) - Math.random() * Math.pow(36, length))).toString(36).slice(1);
}

Is there a step missing?
Yes. You need to create the directory:
mkdir ${HOME}/.ssh
Additionally, SSH requires you to set the permissions so that only you (the owner) can access anything in ~/.ssh:
% chmod 700 ~/.ssh
Should the
.ssh
dir be generated when I use thessh-keygen
command?
No. This command generates an SSH key pair but will fail if it cannot write to the required directory:
% ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): /Users/tmp/does_not_exist
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
open /Users/tmp/does_not_exist failed: No such file or directory.
Saving the key failed: /Users/tmp/does_not_exist.
Once you've created your keys, you should also restrict who can read those key files to just yourself:
% chmod -R go-wrx ~/.ssh/*

Dont forget that you can sometimes just fall off the end of the block to get to the next iteration:
$(".row").each( function() {
if ( ! leaveTheLoop ) {

});
Rather than actually returning like this:
$(".row").each( function() {
if ( leaveTheLoop )
return; //go to next iteration in .each()
... do stuff here ...
});
Also, you can copy an item from the finder using command-C, jump into the Terminal (e.g. using Spotlight or QuickSilver) type 'cd ' and simply paste with command-v

the best way is to change your route. The default route (defined in your App_Start) sets /Home/Index
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters*
new { controller = "Home", action = "Index",
id = UrlParameter.Optional }
);
as the default landing page. You can change that to be any route you wish.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters*
new { controller = "Sales", action = "ProjectionReport",
id = UrlParameter.Optional }
);
I contacted GitHub to say that github.io-hosted SVGs are no longer displayed in GitHub READMEs. I received this reply:
We have had to disable svg image rendering on GitHub.com due to potential cross site scripting vulnerabilities.

For future reference (since this is google's top answer ATM), to prevent jQuery UI from overriding bootstrap's or your custom style, you need to create a custom download and select the no-theme
theme. That will only include jQuery UI's resets, and not overload bootstrap's style for various elements.
While we're at it, some jQuery UI components (such as datepicker) have a native bootstrap implementation. The native bootstrap implementations will use the bootstrap css classes, attributes and layouts, so should have a better integration with the rest of the framework.
If you are looking at graph analysis in C++ probably the first place to start would be the boost graph library, which implements a number of algorithms including BFS.
EDIT
This previous question on SO will probably help:

If you are on SQL Server 2008 or later you can use the date datatype:
SELECT *
FROM [User] U
WHERE CAST(U.DateCreated as DATE) = '2014-02-07'
It should be noted that if date column is indexed then this will still utilise the index and is SARGable. This is a special case for dates and datetimes.
You can see that SQL Server actually turns this into a > and < clause:
I've just tried this on a large table, with a secondary index on the date column as per @kobik's comments and the index is still used, this is not the case for the examples that use BETWEEN or >= and <:
SELECT *
FROM [User] U
WHERE CAST(U.DateCreated as DATE) = '2016-07-05'
Using the Job Control of bash to send the process into the background:
bg
to run it in the background.disown -h [job-spec]
where [job-spec] is the job number (like %1
for the first running job; find about your number with the jobs
command) so that the job isn't killed when the terminal closes.Let say we are creating a drop down list of currency:
List _currency = ["INR", "USD", "SGD", "EUR", "PND"];
List<DropdownMenuItem<String>> _dropDownMenuCurrencyItems;
String _currentCurrency;
List<DropdownMenuItem<String>> getDropDownMenuCurrencyItems() {
List<DropdownMenuItem<String>> items = new List();
for (String currency in _currency) {
items.add(
new DropdownMenuItem(value: currency, child: new Text(currency)));
}
return items;
}
void changedDropDownItem(String selectedCurrency) {
setState(() {
_currentCurrency = selectedCurrency;
});
}
Add below code in body part:
new Row(children: <Widget>[
new Text("Currency: "),
new Container(
padding: new EdgeInsets.all(16.0),
),
new DropdownButton(
value: _currentCurrency,
items: _dropDownMenuCurrencyItems,
onChanged: changedDropDownItem,
)
])
Parris / kindall's answer join

answer ported to Python 3:
from threading import Thread
def foo(bar):
print('hello {0}'.format(bar))
return "foo"
class ThreadWithReturnValue(Thread):
def __init__(self, group=None, target=None, name=None, args=(), kwargs=None, *, daemon=None):
Thread.__init__(self, group, target, name, args, kwargs, daemon=daemon)
self._return = None
def run(self):
if self._target is not None:
self._return = self._target(*self._args, **self._kwargs)
def join(self):
Thread.join(self)
return self._return
twrv = ThreadWithReturnValue(target=foo, args=('world!',))
twrv.start()
print(twrv.join()) # prints foo
Note, the Thread
class is implemented differently in Python 3.
Little sum up for searching by row:
This can be useful if you don't know the column values ??or if columns have non-numeric values
if u want get index number as integer u can also do:
item = df[4:5].index.item()
print(item)
4
it also works in numpy / list:
numpy = df[4:7].index.to_numpy()[0]
lista = df[4:7].index.to_list()[0]
in [x] u pick number in range [4:7], for example if u want 6:
numpy = df[4:7].index.to_numpy()[2]
print(numpy)
6
for DataFrame:
df[4:7]
A B
4 5 0.894525
5 6 0.978174
6 7 0.859449
or:
df[(df.index>=4) & (df.index<7)]
A B
4 5 0.894525
5 6 0.978174
6 7 0.859449
And with the new string formatting method...
f = open('{0}.csv'.format(name), 'wb')
You need use Stream to send file (archive) in a response, what is more you have to use appropriate Content-type in your response header.
There is an example function that do it:
const fs = require('fs');
// Where fileName is name of the file and response is Node.js Reponse.
responseFile = (fileName, response) => {
const filePath = "/path/to/archive.rar" // or any file format
// Check if file specified by the filePath exists
fs.exists(filePath, function(exists){
if (exists) {
// Content-type is very interesting part that guarantee that
// Web browser will handle response in an appropriate manner.
response.writeHead(200, {
"Content-Type": "application/octet-stream",
"Content-Disposition": "attachment; filename=" + fileName
});
fs.createReadStream(filePath).pipe(response);
} else {
response.writeHead(400, {"Content-Type": "text/plain"});
response.end("ERROR File does not exist");
}
});
}
}
The purpose of the Content-Type field is to describe the data contained in the body fully enough that the receiving user agent can pick an appropriate agent or mechanism to present the data to the user, or otherwise deal with the data in an appropriate manner.
"application/octet-stream" is defined as "arbitrary binary data" in RFC 2046, purpose of this content-type is to be saved to disk - it is what you really need.
"filename=[name of file]" specifies name of file which will be downloaded.
For more information please see this stackoverflow topic.
You can also use
cd %localhost%
to set the directory to the folder the batch file was opened from. Your script would look like this:
@echo off
cd %localhost%
echo .> dblank.txt
Make sure you set the directory before you use the command to create the text file.
You can use the data type point
- combines (x,y)
which can be your lat / long. Occupies 16 bytes: 2 float8
numbers internally.
Or make it two columns of type float
(= float8
or double precision
). 8 bytes each.
Or real
(= float4
) if additional precision is not needed. 4 bytes each.
Or even numeric
if you need absolute precision. 2 bytes for each group of 4 digits, plus 3 - 8 bytes overhead.
Read the fine manual about numeric types and geometric types.
The geometry
and geography
data types are provided by the additional module PostGIS and occupy one column in your table. Each occupies 32 bytes for a point. There is some additional overhead like an SRID in there. These types store (long/lat), not (lat/long).
Start reading the PostGIS manual here.

Using Spring's SimpleJdbcTemplate, I got it when I tried to do this:
String sqlString = "select pwy_code from approver where university_id = '123'";
List<Map<String, Object>> rows = getSimpleJdbcTemplate().queryForList(sqlString, uniId);
I had an argument to queryForList that didn't correspond to a question mark in the SQL. The first line should have been:
String sqlString = "select pwy_code from approver where university_id = ?";
To suppress the deprecation message for this alone (and stay informed of other deprecations in your code) you can prefix the connect with @:
<?php
$connect = @mysql_connect('localhost','root','');
mysql_select_db('dbname');
?>
I confirm that git and msysgit can coexist on the same computer, as mentioned in "Which GIT version to use cygwin or msysGit or both?".
Git for Windows (msysgit) will run in its own shell (dos with git-cmd.bat
or bash with Git Bash.vbs
)
Update 2016: msysgit is obsolete, and the new Git for Windows now uses msys2
Git on Cygwin, after installing its package, will run in its own cygwin bash shell.
In there, you can do a sudo apt-get install git-core
and start using git on project-sources present either on the WSL container's "native" file-system (see below), or in the hosting Windows's file-system through the /mnt/c/...
, /mnt/d/...
directory hierarchies.
Specifically for the Bash on Windows or WSL (Windows Subsystem for Linux):
DrvFs
emulated file-system may not behave the same as files on the native VolFs
file-system).
- Unfortunately, it cannot invoke back into Windows executables, or
- interact with any native drivers (i.e. so no Graphic card, no USB drives yet).
You can use IF EXIST to check for a file:
IF EXIST "filename" (
REM Do one thing
) ELSE (
REM Do another thing
)
If you do not need an "else", you can do something like this:
set __myVariable=
IF EXIST "C:\folder with space\myfile.txt" set __myVariable=C:\folder with space\myfile.txt
IF EXIST "C:\some other folder with space\myfile.txt" set __myVariable=C:\some other folder with space\myfile.txt
set __myVariable=
Here's a working example of searching for a file or a folder:
REM setup
echo "some text" > filename
mkdir "foldername"
REM finds file
IF EXIST "filename" (
ECHO file filename exists
) ELSE (
ECHO file filename does not exist
)
REM does not find file
IF EXIST "filename2.txt" (
ECHO file filename2.txt exists
) ELSE (
ECHO file filename2.txt does not exist
)
REM folders must have a trailing backslash
REM finds folder
IF EXIST "foldername\" (
ECHO folder foldername exists
) ELSE (
ECHO folder foldername does not exist
)
REM does not find folder
IF EXIST "filename\" (
ECHO folder filename exists
) ELSE (
ECHO folder filename does not exist
)
The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.
The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?
Using an Cursor FOR LOOP Statement is my favourite way to do this.
It is safer than using an explicit cursor, because you don't need to remember to close it, so you can't "leak" cursors.
You don't need "into" variables, you don't need to "FETCH", you don't need to catch and handle "NO DATA FOUND" exceptions.
Try it, you'll never go back.
v_column my_table.column%TYPE;
v_column := null;
FOR rMyTable IN (SELECT COLUMN FROM MY_TABLE WHERE ....) LOOP
v_column := rMyTable.COLUMN;
EXIT; -- Exit the loop if you only want the first result.
END LOOP;
A combination of previous 2 answers did the trick. Thanks. A new class which inherits from Button. Note: updateImages() should be called before showing the button.

import javafx.scene.control.Button;
import javafx.scene.image.Image;

final ImageView iv = new ImageView(selected);
this.getChildren().add(iv);
iv.setOnMousePressed(new EventHandler<MouseEvent>() {
public void handle(MouseEvent evt) {
iv.setImage(unselected);
}
});
iv.setOnMouseReleased(new EventHandler<MouseEvent>() {
public void handle(MouseEvent evt) {
iv.setImage(selected);
}
});
super.setGraphic(iv);
}
}

Yes, in VS2010 they changed this behavior somewhy.
Open your project and navigate to the following menu: Project -> YourProjectName Properties -> Configuration Properties -> Linker -> System. There in the field SubSystem use the drop-down to select Console (/SUBSYSTEM:CONSOLE) and apply the change.
"Start without debugging" should do the right thing now.
Or, if you write in C++ or in C, put
system("pause");
at the end of your program, then you'll get "Press any key to continue..." even when running in debug mode.
This gets a little complicated. These objects are custom classes or structs, and looking inside them is not as easy on Xcode as in other development environments.
If I were you, I'd NSLog the values you want to see, with some description.

Do it in 2 steps. First, create a dictionary.
>>> input = [('11013331', 'KAT'), ('9085267', 'NOT'), ('5238761', 'ETH'), ('5349618', 'ETH'), ('11788544', 'NOT'), ('962142', 'ETH'), ('7795297', 'ETH'), ('7341464', 'ETH'), ('9843236', 'KAT'), ('5594916', 'ETH'), ('1550003', 'ETH')]
>>> from collections import defaultdict
>>> res = defaultdict(list)
>>> for v, k in input: res[k].append(v)
...
Then, convert that dictionary into the expected format.
>>> [{'type':k, 'items':v} for k,v in res.items()]
[{'items': ['9085267', '11788544'], 'type': 'NOT'}, {'items': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}, {'items': ['11013331', '9843236'], 'type': 'KAT'}]
It is also possible with itertools.groupby but it requires the input to be sorted first.
>>> sorted_input = sorted(input, key=itemgetter(1))
>>> groups = groupby(sorted_input, key=itemgetter(1))
>>> [{'type':k, 'items':[x[0] for x in v]} for k, v in groups]
[{'items': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}, {'items': ['11013331', '9843236'], 'type': 'KAT'}, {'items': ['9085267', '11788544'], 'type': 'NOT'}]
Note both of these do not respect the original order of the keys. You need an OrderedDict if you need to keep the order.
>>> from collections import OrderedDict
>>> res = OrderedDict()
>>> for v, k in input:
... if k in res: res[k].append(v)
... else: res[k] = [v]
...
>>> [{'type':k, 'items':v} for k,v in res.items()]
[{'items': ['11013331', '9843236'], 'type': 'KAT'}, {'items': ['9085267', '11788544'], 'type': 'NOT'}, {'items': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}]

Found Dmitry Evseev answer quite useful.
Case 1 : Using angularJs alone:
To execute a method on page load, you can use ng-init
in the view and declare init method in controller, having said that use of heavier function is not recommended, as per the angular Docs on ng-init:
This directive can be abused to add unnecessary amounts of logic into your templates. There are only a few appropriate uses of ngInit, such as for aliasing special properties of ngRepeat, as seen in the demo below; and for injecting data via server side scripting. Besides these few cases, you should use controllers rather than ngInit to initialize values on a scope.
HTML:
<div ng-controller="searchController()">
<!-- renaming view code here, including the search box and the buttons -->
</div>
Controller:
app.controller('SearchCtrl', function(){
var doSearch = function(keyword){
//Search code here
}
doSearch($routeParams.searchKeyword);
})
Warning : Do not use this controller for another view meant for a different intention as it will cause the search method be executed there too.
Case 2 : Using Ionic:
The above code will work, just make sure the view cache is disabled in the route.js
as:
route.js
.state('app', {
url : '/search',
cache : false, //disable caching of the view here
templateUrl : 'templates/search.html' ,
controller : 'SearchCtrl'
})
Hope this helps
Sometime it will override by some rendering UI CSS. Better to use:
a.className {
text-decoration: none !important;

To reload a page with jQuery, do:
$.ajax({
url: "",
context: document.body,
success: function(s,x){
$(this).html(s);
}
});
The approach here that I used was Ajax jQuery. I tested it on Chrome 13. Then I put the code in the handler that will trigger the reload. The URL is ""
, which means this page.
I got the same issue on standalone spark in windows. My version of fix is like this: I had my environment variables setting as bellow
PYSPARK_SUBMIT_ARGS="pyspark-shell"
PYSPARK_DRIVER_PYTHON=jupyter
PYSPARK_DRIVER_PYTHON_OPTS='notebook' pyspark
With this setting I executed an Action on pyspark and got the following exception:
Python in worker has different version 3.6 than that in driver 3.5, PySpark cannot run with different minor versions.
Please check environment variables PYSPARK_PYTHON and PYSPARK_DRIVER_PYTHON are correctly set.
To check with which python version my spark-worker is using hit the following in the cmd prompt.
python --version
Python 3.6.3
which showed me Python 3.6.3. So clearly my spark-worker is using system python which is v3.6.3.
Now as I set my spark-driver to run jupyter by setting PYSPARK_DRIVER_PYTHON=jupyter
so I need to check the python version jupyter is using.
To do this check open Anaconda Prompt and hit
python --version
Python 3.5.X :: Anaconda, Inc.
Here got the jupyter python is using the v3.5.x. You can check this version also in any Notebook (Help->About).
Now I need to update the jupyter python to the version v3.6.6. To do that open up the Anaconda Prompt and hit
conda search python
This will give you a list of available python versions in Anaconda. Install your desired one with
conda install python=3.6.3
Now I have both of the Python installation of same version 3.6.3 Spark should not comply and it didn't when I ran an Action on Spark-driver. Exception is gone. Happy coding ...

You're getting errors 'table liam does not exist' because the table's name is Liam
which is not the same as liam
. MySQL table names are case sensitive.
This has worked for me in the past and it will even expand environment variables in the file if it can.

go to ~/.android if there is no debug.keystore copy it from your project and paste it here then run command again.
CSS 3 introduces the background-size property, but support is not universal.
Having the browser resize the image is inefficient though, the large image still has to be downloaded. You should resize it server side (caching the result) and use that instead. It will use less bandwidth and work in more browsers.
You can use AppCompat Support Library for Borderless Button.
You can make a Borderless Button like this:
<Button
style="@style/Widget.AppCompat.Button.Borderless"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:text="@string/borderless_button"/>
You can make Borderless Colored Button like this:
<Button
style="@style/Widget.AppCompat.Button.Borderless.Colored"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:text="@string/borderless_colored_button"/>
Natively the only way is by creating an <input type="file">
element and then simulating a click, unfortunately.
There's a tiny plugin (shameless plug) which will take the pain away of having to do this all the time: file-dialog
fileDialog()
.then(file => {
const data = new FormData()
data.append('file', file[0])
data.append('imageName', 'flower')
// Post to server
fetch('/uploadImage', {
method: 'POST',
body: data
})
})
I added Anaconda3/Library/Bin
to the environment path and PyCharm no longer complained with the error.

If jQuery UI datepicker isn't working but it used to work on similar DOM earlier, try removing all the classes and try binding it to just a simple input with its id. In my case a class was interfering with it and preventing the date picker to appear.
This will work in ES5, ES6, all browsers and strict mode functions.

In my case I was using a gradle project with subprojects. The reason IntelliJ couldn't find declarations was that the subprojects were not built.
After investigating why subprojects were not built, I found out that using "auto-import" was breaking the subprojects.
After importing the project from build.gradle
without auto-import, it worked for me.
To understand those phrases let's look at the couple of things:
typedef double Foo;
void fooFunc(Foo &_bar){ ... }
So that's passing a double by reference.
typedef double* Foo;
void fooFunc(Foo &_bar){ ... }
now it's passing a pointer to a double by reference.
typedef double** Foo;
void fooFunc(Foo &_bar){ ... }
Finally, it's passing a pointer to a pointer to a double by reference. If you think in terms of typedefs like this you'll understand the proper ordering of the & and * plus what it means.
For MySQL, there is none: MySQL Feature Request.
Allowing this is arguably a really bad idea, anyway: IF EXISTS
indicates that you're running destructive operations on a database with (to you) unknown structure. There may be situations where this is acceptable for quick-and-dirty local work, but if you're tempted to run such a statement against production data (in a migration etc.), you're playing with fire.
But if you insist, it's not difficult to simply check for existence first in the client, or to catch the error.
MariaDB also supports the following starting with 10.0.2:
DROP [COLUMN] [IF EXISTS] col_name
i. e.
ALTER TABLE my_table DROP IF EXISTS my_column;
But it's arguably a bad idea to rely on a non-standard feature supported by only one of several forks of MySQL.
You may be victim of a garbage collection problem.
When your application requires memory and it's getting low on what it's configured to use the garbage collector will run often which consume a lot of CPU cycles. If it can't collect anything your memory will stay low so it will be run again and again. When you redeploy your application the memory is cleared and the garbage collection won't happen more than required so the CPU utilization stays low until it's full again.
You should check that there is no possible memory leak in your application and that it's well configured for memory (check the -Xmx
parameter, see What does Java option -Xmx stand for?)
Also, what are you using as web framework? JSF relies a lot on sessions and consumes a lot of memory, consider being stateless at most!
You can use numpy.count_nonzero, converting the whole into a one-liner:

.parent {
display:flex;
height:100vh;
}
.child{
flex-grow:1;
}
.left{
background:#ddd;
}
.center{
background:#666;
}
.right{
background:#999;
}
HTML
<div class="parent">
<div class="child left">Left</div>
<div class="child center">Center</div>
<div class="child right">Right</div>
</div>
You can try the same in js fiddle.
You can compile with either Cygwin's g++
or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll
(and others) PATH to the system Windows PATH, before any cygwin style paths.
Thus add: ;C:\cygwin64\bin
to the end of your Windows system PATH
variable.
Also, to compile for use in CMD or PowerShell, you may need to use:
x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe
(This invokes the cross-compiler, if installed.)
Change
$array=array_map('intval', explode(',', $string));
To:
$array= implode(',', array_map('intval', explode(',', $string)));
array_map returns an array, not a string. You need to convert the array to a comma separated string in order to use in the WHERE clause.
Here is another way. No intermediate variables are saved.
We used this to de-duplicate results from a variety of overlapping queries.
$input = array_map("unserialize", array_unique(array_map("serialize", $input)));
You can use COPY. You need to specify the directory explicitly. It won't be created by itself
COPY go /usr/local/go
Reference: Docker CP reference
You could use setInterval
for this.
<script type="text/javascript">
function myFunction () {
console.log('Executed!');
}
var interval = setInterval(function () { myFunction(); }, 60000);
</script>
Disable the timer by setting clearInterval(interval)
.

Did not find a solution after trying the above answers - Maybe this is very specific to my case - Solution was to ensure that the option "Skip All Breakpoints" is not enabled in Eclipse Run - > Skip All Breakpoints (ctl-alt-B) (toggle)
What you have there will return no row at all if the user doesn't exist. Here's what you need:
SELECT CASE WHEN EXISTS (
SELECT *
FROM [User]
WHERE UserID = 20070022
)
THEN CAST(1 AS BIT)
ELSE CAST(0 AS BIT) END
Looks like you've not encapsulated your string properly. Try this:
INSERT INTO custorder VALUES ('Kevin','yes'), STR_TO_DATE('1-01-2012', '%d-%m-%Y');
Alternatively, you can do the following but it is not recommended. Make sure that you use STR_TO-DATE it is because when you are developing web applications you have to explicitly convert String to Date which is annoying. Use first One.
INSERT INTO custorder VALUES ('Kevin','yes'), '2012-01-01';
I'm not confident that the above SQL is valid, however, and you may want to move the date part into the brackets. If you can provide the exact error you're getting, I might be able to more directly help with the issue.
Create a UILabel
with the title you want for your root view controller and assign it to the view controller's navigationItem.titleView
.
Now set the title to an empty string and the next view controller you push will have a back button without text.
self.navigationItem.titleView = titleLabel; //Assuming you've created titleLabel above
self.title = @"";
