This is a follow up to my original question to help out others with the same problem. If you need to filter by an attribute, rather than manually looking up the id you can use the following code to retrieve all the id, value pairs for an attribute. The data is returned as an array with the attribute name as the key.
function getAttributeOptions($attributeName) {
$product = Mage::getModel('catalog/product');
$collection = Mage::getResourceModel('eav/entity_attribute_collection')
->setEntityTypeFilter($product->getResource()->getTypeId())
->addFieldToFilter('attribute_code', $attributeName);
$_attribute = $collection->getFirstItem()->setEntity($product->getResource());
$attribute_options = $_attribute->getSource()->getAllOptions(false);
foreach($attribute_options as $val) {
$attrList[$val['label']] = $val['value'];
}
return $attrList;
}
Here is a function you can use to get products by their attribute set id. Retrieved using the previous function.
function getProductsByAttributeSetId($attributeSetId) {
$products = Mage::getModel('catalog/product')->getCollection();
$products->addAttributeToFilter('attribute_set_id',$attributeSetId);
$products->addAttributeToSelect('*');
$products->load();
foreach($products as $val) {
$productsArray[] = $val->getData();
}
return $productsArray;
}
What's so confusing about it... getters are functions that are called when you get a property, setters, when you set it. example, if you do
obj.prop = "abc";
You're setting the property prop, if you're using getters/setters, then the setter function will be called, with "abc" as an argument. The setter function definition inside the object would ideally look something like this:
set prop(var) {
// do stuff with var...
}
I'm not sure how well that is implemented across browsers. It seems Firefox also has an alternative syntax, with double-underscored special ("magic") methods. As usual Internet Explorer does not support any of this.
Use %0A
(URL encoding) instead of \n
(C encoding).
I too faced this problem when loading an 'http' url in WKWebView in iOS 11, it is working fine with https.
What worked for me was setting App transport setting in info.pist file to allow arbitary load.
<key>NSAppTransportSecurity</key>
<dict>
<!--Not a recommended way, there are better solutions available-->
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
12
is a compile-time constant which can not be changed unlike the data referenced by int&
. What you can do is
const int& z = 12;
I was receiving the error (I'm using Vue) and I switched my onclick="someFunction()"
to @click="someFunction"
and now they are working.
I tried above answers and they didn't help in my case.
I solved it with this link help: http://vjscrazzy.blogspot.co.il/2016/02/failed-to-sync-gradle-project.html
step 1) file>Setttings>appearance and behaviour> system setttings>HTTP proxy> set No Proxy
step 2) build,execution and deployment> Build tools > gradle> now under project level settings > select local gradle distribution> gradle home = F:/Program Files/Android/Android Studio/gradle/gradle-2.4
After that, I did these changes(because it still wrote me some other errors)
Android Studio asked me:
Android Studio asked me to update my Gradle version (which he didn't before)

Also, if your working in a team with repositories, it's important to check that the version of the Andorid Studio is the same.
You can not alter constraints ever but you can drop them and then recreate.
Have look on this
ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;
and then recreate it with ON DELETE CASCADE
like this
ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
ON DELETE CASCADE;
hope this help
Use QString::arg()
for the same effect.
Directory Services/LDAP lookups can be used to serve this purpose. It involves some changes at infrastructure level, but most production environments have such provision
In general, you must have a file handle before opening the stream. You have a fileOutputStream handle before createNewFile() in the else block. The stream does not create the file if it doesn't exist.
Not really android specific, but that's a lot IO for this purpose. What if you do many "write" operations one after another? You will be reading the entire contents and writing the entire contents, taking time, and more importantly, battery life.
I suggest using java.io.RandomAccessFile, seek()'ing to the end, then writeChars() to append. It will be much cleaner code and likely much faster.
You have different line endings in the example texts in Debuggex. What is especially interesting is that Debuggex seems to have identified which line ending style you used first, and it converts all additional line endings entered to that style.
I used Notepad++ to paste sample text in Unix and Windows format into Debuggex, and whichever I pasted first is what that session of Debuggex stuck with.
So, you should wash your text through your text editor before pasting it into Debuggex. Ensure that you're pasting the style you want. Debuggex defaults to Unix style (\n).
Also, NEL (\u0085) is something different entirely: https://en.wikipedia.org/wiki/Newline#Unicode
(\r?\n)
will cover Unix and Windows. You'll need something more complex, like (\r\n|\r|\n)
, if you want to match old Mac too.
The simplest method is to use LIKE
:
SELECT CASE WHEN 'FDAJLK' LIKE '%[0-9]%' THEN 'True' ELSE 'False' END; -- False
SELECT CASE WHEN 'FDAJ1K' LIKE '%[0-9]%' THEN 'True' ELSE 'False' END; -- True
Will it warn you if you pass a 32-bit unsigned integer to a %lu format? It should be fine since the conversion is well-defined and doesn't lose any information.
I've heard that some platforms define macros in <inttypes.h>
that you can insert into the format string literal but I don't see that header on my Windows C++ compiler, which implies it may not be cross-platform.
you can set a password to your vba code but this can be quite easily broken up.
you can also create an addin and compile it into a DLL. See here for more information. That's at least the most secure way to protect your code.

Interesting/funny way to do this using parameter expansion (requires bash 4.4
or newer):
${parameter@operator} - P operator
The expansion is a string that is the result of expanding the value of parameter as if it were a prompt string.
$ show_time() { local format='\D{%Y%m%d%H%M%S}'; echo "${format@P}"; }
$ show_time

I know this is an old question, but gracchus's solution doesn't work if file names contain spaces. VonC's solution to file names with spaces is to not remove them utilizing --ignore-unmatch
, then remove them manually, but this will not work well if there are a lot.
Here is a solution that utilizes bash arrays to capture all files.
# Build bash array of the file names
while read -r file; do
rmlist+=( "$file" )
done < <(git ls-files -i --exclude-standard)
git rm –-cached "${rmlist[@]}"
git commit -m 'ignore update'
I would imagine that it has to do with encoding. A char
is 16 bytes and some encodings will use one byte for a character whereas another will use two or even more. When Java was originally designed, they assumed that any Unicode character would fit in 2 bytes, whereas now a Unicode character can require up to 4 bytes (UTF-32). There is no way for Scanner
to represent a UTF-32 codepoint in a single char
.
You can specify an encoding to Scanner
when you construct an instance, and if not provided, it will use the platform character-set. But this still doesn't handle the issue with 3 or 4 byte Unicode characters, since they cannot be represented as a single char
primitive (since char
is only 16 bytes). So you would end up getting inconsistent results.
boolean
is a primitive type, and therefore can not be null.
Its boxed type, Boolean
, can be null.
The function is probably returning a Boolean
as opposed to a boolean
, so assigning the result to a Boolean
-type variable will allow you to test for nullity.
In case you are reading this answer because you are facing "resource file not found" error, try this:
Output Layout
, press Create Archive
to create a new jar, and again, give it a nice name ;)Manifest File
then set correct Main Class
and Class Path
.Add Library Files
, and select libraries you need (you can use Ctrl+A to select all).I am assuming you want to set the opacity of the modal background...
Set the opacity via CSS
.modal-backdrop
{
opacity:0.5 !important;
}
!important
prevents the opacity from being overwritten - particularly from Bootstrap in this context.
As of Gradle 4.9 Application plugin understands --args
option, so passing the arguments is as simple as:
build.gradle
plugins {
id 'application'
}
mainClassName = "my.App"
src/main/java/my/App.java
public class App {
public static void main(String[] args) {
System.out.println(args);
}
}
bash
./gradlew run --args='This string will be passed into my.App#main arguments'
or in Windows, use double quotes:
gradlew run --args="This string will be passed into my.App#main arguments"
Linux Solution: For example, you want to see all files/folder list of your home (/) directory according to file/folder size (Descending order).
sudo du -xm / | sort -rn | more
I had same problem once. every things seems right. I restart, delete and invalidate cache of Android studio, rebuild, clean and nothings changed. It is finally solved by click on Sync Project with Gradle Files button in android studio 3.0
I had the same problem, what helped we was turning of my anti virus protection for like 10 minutes while node installed and it worked like a charm.
Since 5.0, you can now find those values in a dedicated Enum
: org.hibernate.boot.SchemaAutoTooling
(enhanced with value NONE
since 5.2).
Or even better, since 5.1, you can also use the org.hibernate.tool.schema.Action
Enum
which combines JPA 2 and "legacy" Hibernate DDL actions.
But, you cannot yet configure a DataSource
programmatically with this. It would be nicer to use this combined with org.hibernate.cfg.AvailableSettings#HBM2DDL_AUTO
but the current code expect a String
value (excerpt taken from SessionFactoryBuilderImpl
):
this.schemaAutoTooling = SchemaAutoTooling.interpret( (String) configurationSettings.get( AvailableSettings.HBM2DDL_AUTO ) );
… and internal enum
values of both org.hibernate.boot.SchemaAutoTooling
and org.hibernate.tool.schema.Action
aren't exposed publicly.
Hereunder, a sample programmatic DataSource
configuration (used in ones of my Spring Boot applications) which use a gambit thanks to .name().toLowerCase()
but it only works with values without dash (not create-drop
for instance):
@Bean(name = ENTITY_MANAGER_NAME)
public LocalContainerEntityManagerFactoryBean internalEntityManagerFactory(
EntityManagerFactoryBuilder builder,
@Qualifier(DATA_SOURCE_NAME) DataSource internalDataSource) {
Map<String, Object> properties = new HashMap<>();
properties.put(AvailableSettings.HBM2DDL_AUTO, SchemaAutoTooling.CREATE.name().toLowerCase());
properties.put(AvailableSettings.DIALECT, H2Dialect.class.getName());
return builder
.dataSource(internalDataSource)
.packages(JpaModelsScanEntry.class, Jsr310JpaConverters.class)
.persistenceUnit(PERSISTENCE_UNIT_NAME)
.properties(properties)
.build();
}
Responding to pzulw's feedback to sandroid about specifying the intent.
The format of the component name is described in the api docs for ComponentName.unflattenFromString
It splits the string at the first '/', taking the part before as the package name and the part after as the class name. As a special convenience (to use, for example, when parsing component names on the command line), if the '/' is immediately followed by a '.' then the final class name will be the concatenation of the package name with the string following the '/'. Thus "com.foo/.Blah" becomes package="com.foo" class="com.foo.Blah".
Mootools also has a nice 'Tips' class available in their 'more builder'.
This can happen when the owner of the SQLite file itself is not the same as the user running the script. Similar errors can occur if the entire directory path (meaning each directory along the way) can't be written to.
Who owns the SQLite file? You?
Who is the script running as? Apache or Nobody?
I know this has an acceptable answer, but I ran into a situation where clientWidth
didn't work, as iPhone (at least mine) returned 980, not 320, so I used window.screen.width
. I was working on existing site, being made "responsive" and needed to force larger browsers to use a different meta-viewport.
Hope this helps someone, it may not be perfect, but it works in my testing on iOs and Android.
//sweet hack to set meta viewport for desktop sites squeezing down to mobile that are big and have a fixed width
//first see if they have window.screen.width avail
(function() {
if (window.screen.width)
{
var setViewport = {
//smaller devices
phone: 'width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no',
//bigger ones, be sure to set width to the needed and likely hardcoded width of your site at large breakpoints
other: 'width=1045,user-scalable=yes',
//current browser width
widthDevice: window.screen.width,
//your css breakpoint for mobile, etc. non-mobile first
widthMin: 560,
//add the tag based on above vars and environment
setMeta: function () {
var params = (this.widthDevice <= this.widthMin) ? this.phone : this.other;
var head = document.getElementsByTagName("head")[0];
var viewport = document.createElement('meta');
viewport.setAttribute('name','viewport');
viewport.setAttribute('content',params);
head.appendChild(viewport);
}
}
//call it
setViewport.setMeta();
}
}).call(this);
In my case the error was not caused by any of the above xml namespace issues. Instead it was the location of the android:id
attribute - it needed to be the first item in the particular element's declaration.
So this:
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/bottomtext"
android:singleLine="true" />
... needed to read like this:
<TextView android:id="@+id/bottomtext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true" />
Try this:
Get-ChildItem C:\windows\System32 -Include *.txt -Recurse | select -ExpandProperty FullName
Actually every logger is a child of the parent's package logger (i.e. package.subpackage.module
inherits configuration from package.subpackage)
, so all you need to do is just to configure the root logger. This can be achieved by logging.config.fileConfig
(your own config for loggers) or logging.basicConfig
(sets the root logger). Setup logging in your entry module (__main__.py
or whatever you want to run, for example main_script.py
. __init__.py
works as well)
using basicConfig:
# package/__main__.py
import logging
import sys
logging.basicConfig(stream=sys.stdout, level=logging.INFO)
using fileConfig:
# package/__main__.py
import logging
import logging.config
logging.config.fileConfig('logging.conf')
and then create every logger using:
# package/submodule.py
# or
# package/subpackage/submodule.py
import logging
log = logging.getLogger(__name__)
log.info("Hello logging!")
For more information see Advanced Logging Tutorial.
NOTE: this does not answer to the common problem, which was OP’s problem, but to different problem where this error message may come up. I didn’t feel like doing new question just to write this answer down, tell me if I should do that instead :P
I got to situation, most likely due to some corruption of certain crash I had, that I got this error even when .git
did exist.
smar@aaeru ~/P/Nominatim> git status
fatal: Not a git repository (or any of the parent directories): .git
smar@aaeru ~/P/Nominatim [128]> ls .git
COMMIT_EDITMSG config* FETCH_HEAD HEAD index logs/ modules/ objects/ ORIG_HEAD packed-refs
Since I didn’t have anything that really needed preserving, I just went with dummy way, and did...
smar@aaeru ~/P/Nominatim [128]> git init
Reinitialized existing Git repository in /home/smar/Projektit/Nominatim/.git/
Still not working though, as for example git log
returns fatal: bad default revision 'HEAD'
. Remotes were there though, so I did git fetch --all
and then just git reset --hard origin/master
to get myself to the state the repo was previously.
Note that if there is some uncommitted changes, you can see them with git status
, git diff
and so on. Then just git diff yourfile > patch
before running the reset.
At least for me reflog (git reflog
) disappeared completely. Hence, if you do the reset, and there was some changes you wanted to prevent, I’m not sure you can get them back after reset anymore. So, make sure that you have all changes you can’t lose backed up, ultimately by just copying the clone before trying this.
How about this:
if all([key in foo for key in ["foo","bar"]]):
# do stuff
pass

Worked for me after installing scipy.
Strings are immutable types. You cannot modify them, only return new string instances.
Because of that, formatting with an instance method makes little sense, as it would have to be called like:
String formatted = "%s: %s".format(key, value);
The original Java authors (and .NET authors) decided that a static method made more sense in this situation, as you are not modifying the target, but instead calling a format method and passing in an input string.
Here is an example of why format()
would be dumb as an instance method. In .NET (and probably in Java), Replace()
is an instance method.
You can do this:
"I Like Wine".Replace("Wine","Beer");
However, nothing happens, because strings are immutable. Replace()
tries to return a new string, but it is assigned to nothing.
This causes lots of common rookie mistakes like:
inputText.Replace(" ", "%20");
Again, nothing happens, instead you have to do:
inputText = inputText.Replace(" ","%20");
Now, if you understand that strings are immutable, that makes perfect sense. If you don't, then you are just confused. The proper place for Replace()
would be where format()
is, as a static method of String
:
inputText = String.Replace(inputText, " ", "%20");
Now there is no question as to what's going on.
The real question is, why did the authors of these frameworks decide that one should be an instance method, and the other static? In my opinion, both are more elegantly expressed as static methods.
Regardless of your opinion, the truth is that you are less prone to make a mistake using the static version, and the code is easier to understand (No Hidden Gotchas).
Of course there are some methods that are perfect as instance methods, take String.Length()
int length = "123".Length();
In this situation, it's obvious we are not trying to modify "123", we are just inspecting it, and returning its length. This is a perfect candidate for an instance method.
My simple rules for Instance Methods on Immutable Objects:
To create a new commit that 'undoes' the changes of a past commit, use:
$ git revert <commit-hash>
It's also possible to actually remove a commit from an arbitrary point in the past by rebasing and then resetting, but you really don't want to do that if you have already pushed your commits to another repository (or someone else has pulled from you).
If your previous commit is a merge commit you can run this command
$ git revert -m 1 <commit-hash>
See schacon.github.com/git/howto/revert-a-faulty-merge.txt for proper ways to re-merge an un-merged branch

The length of the text that you are providing in each line is different, this is the problem, so if the second word is too long (see2.txt
is long 8 char which corresponds to a single tab lenght) it prints out a tab which goes to the next tabulation point.
One way to solve it is to programmatically add a pad to the f.getName()
text so each text generated: see.txt
or see2.txt
has the same lenght (for example see.txt_
and see2.txt
) so each tab automatically goes to the same tabulation point.
If you are developing with JDK 1.5 you can solve this using java.util.Formatter:
String format = "%-20s %5d\n";
System.out.format(format, "test", 1);
System.out.format(format, "test2", 20);
System.out.format(format, "test3", 5000);
this example will give you this print:
test 1
test2 20
test3 5000
The problem with MAC address is that there can be many network adapters connected to the computer. Most of the newest ones have two by default (wi-fi + cable). In such situation one would have to know which adapter's MAC address should be used. I tested MAC solution on my system, but I have 4 adapters (cable, WiFi, TAP adapter for Virtual Box and one for Bluetooth) and I was not able to decide which MAC I should take... If one would decide to use adapter which is currently in use (has addresses assigned) then new problem appears since someone can take his/her laptop and switch from cable adapter to wi-fi. With such condition MAC stored when laptop was connected through cable will now be invalid.
For example those are adapters I found in my system:
lo MS TCP Loopback interface
eth0 Intel(R) Centrino(R) Advanced-N 6205
eth1 Intel(R) 82579LM Gigabit Network Connection
eth2 VirtualBox Host-Only Ethernet Adapter
eth3 Sterownik serwera dostepu do sieci LAN Bluetooth
Code I've used to list them:
Enumeration<NetworkInterface> nis = NetworkInterface.getNetworkInterfaces();
while (nis.hasMoreElements()) {
NetworkInterface ni = nis.nextElement();
System.out.println(ni.getName() + " " + ni.getDisplayName());
}
From the options listen on this page, the most acceptable for me, and the one I've used in my solution is the one by @Ozhan Duz, the other one, similar to @finnw answer where he used JACOB, and worth mentioning is com4j - sample which makes use of WMI is available here:
ISWbemLocator wbemLocator = ClassFactory.createSWbemLocator();
ISWbemServices wbemServices = wbemLocator.connectServer("localhost","Root\\CIMv2","","","","",0,null);
ISWbemObjectSet result = wbemServices.execQuery("Select * from Win32_SystemEnclosure","WQL",16,null);
for(Com4jObject obj : result) {
ISWbemObject wo = obj.queryInterface(ISWbemObject.class);
System.out.println(wo.getObjectText_(0));
}
This will print some computer information together with computer Serial Number. Please note that all classes required by this example has to be generated by maven-com4j-plugin. Example configuration for maven-com4j-plugin:
<plugin>
<groupId>org.jvnet.com4j</groupId>
<artifactId>maven-com4j-plugin</artifactId>
<version>1.0</version>
<configuration>
<libId>565783C6-CB41-11D1-8B02-00600806D9B6</libId>
<package>win.wmi</package>
<outputDirectory>${project.build.directory}/generated-sources/com4j</outputDirectory>
</configuration>
<executions>
<execution>
<id>generate-wmi-bridge</id>
<goals>
<goal>gen</goal>
</goals>
</execution>
</executions>
</plugin>
Above's configuration will tell plugin to generate classes in target/generated-sources/com4j directory in the project folder.
For those who would like to see ready-to-use solution, I'm including links to the three classes I wrote to get machine SN on Windows, Linux and Mac OS:
You could also pass points to the function: Small example:

return points;
if __name__ == '__main__':
points = 0
for i in range(10):
points = test(points)

If you do not need the recording and playback functionality in your app, using off-the-shelf streaming app and player is a reasonable choice.
If you do need them to be in your app, however, you will have to look into MediaRecorder API (for the server/camera app) and MediaPlayer (for client/player app).
Quick sample code for the server:
// this is your network socket
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mCamera = getCameraInstance();
mMediaRecorder = new MediaRecorder();
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// this is the unofficially supported MPEG2TS format, suitable for streaming (Android 3.0+)
mMediaRecorder.setOutputFormat(8);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setOutputFile(pfd.getFileDescriptor());
mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
mMediaRecorder.prepare();
mMediaRecorder.start();
On the player side it is a bit tricky, you could try this:
// this is your network socket, connected to the server
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(pfd.getFileDescriptor());
mMediaPlayer.prepare();
mMediaPlayer.start();
Unfortunately mediaplayer tends to not like this, so you have a couple of options: either (a) save data from socket to file and (after you have a bit of data) play with mediaplayer from file, or (b) make a tiny http proxy that runs locally and can accept mediaplayer's GET request, reply with HTTP headers, and then copy data from the remote server to it. For (a) you would create the mediaplayer with a file path or file url, for (b) give it a http url pointing to your proxy.

For a simple Spring application, you don't have to define ContextLoaderListener
in your web.xml
; you can just put all your Spring configuration files in <servlet>
:
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/mvc-core-config.xml, classpath:spring/business-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
For a more complex Spring application, where you have multiple DispatcherServlet
defined, you can have the common Spring configuration files that are shared by all the DispatcherServlet
defined in the ContextLoaderListener
:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/common-config.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>mvc1</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/mvc1-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet>
<servlet-name>mvc2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/mvc2-config.xmll</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Just keep in mind, ContextLoaderListener
performs the actual initialization work for the root application context.

android.view.WindowManager$BadTokenException: Unable to add window"
Problem :
This exception occurs when the app is trying to notify the user from the background thread (AsyncTask) by opening a Dialog.
If you are trying to modify the UI from background thread (usually from onPostExecute() of AsyncTask) and if the activity enters finishing stage i.e.) explicitly calling finish(), user pressing home or back button or activity clean up made by Android then you get this error.
Reason :
The reason for this exception is that, as the exception message says, the activity has finished but you are trying to display a dialog with a context of the finished activity. Since there is no window for the dialog to display the android runtime throws this exception.
Solution:
Use
isFinishing()
method which is called by Android to check whether this activity is in the process of finishing: be it explicit finish() call or activity clean up made by Android. By using this method it is very easy to avoid opening dialog from background thread when activity is finishing.Also maintain a
weak reference
for the activity (and not a strong reference so that activity can be destroyed once not needed) and check if the activity is not finishing before performing any UI using this activity reference (i.e. showing a dialog).
eg.
private class chkSubscription extends AsyncTask<String, Void, String>{
private final WeakReference<login> loginActivityWeakRef;
public chkSubscription (login loginActivity) {
super();
this.loginActivityWeakRef= new WeakReference<login >(loginActivity)
}
protected String doInBackground(String... params) {
//web service call
}
protected void onPostExecute(String result) {
if(page.contains("error")) //when not subscribed
{
if (loginActivityWeakRef.get() != null && !loginActivityWeakRef.get().isFinishing()) {
AlertDialog.Builder builder = new AlertDialog.Builder(login.this);
builder.setCancelable(true);
builder.setMessage(sucObject);
builder.setInverseBackgroundForced(true);
builder.setNeutralButton("Ok",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton){
dialog.dismiss();
}
});
builder.show();
}
}
}
}
Update :
Window Tokens:
As its name implies, a window token is a special type of Binder token that the window manager uses to uniquely identify a window in the system. Window tokens are important for security because they make it impossible for malicious applications to draw on top of the windows of other applications. The window manager protects against this by requiring applications to pass their application's window token as part of each request to add or remove a window. If the tokens don't match, the window manager rejects the request and throws a BadTokenException. Without window tokens, this necessary identification step wouldn't be possible and the window manager wouldn't be able to protect itself from malicious applications.
A real-world scenario:
When an application starts up for the first time, the ActivityManagerService creates a special kind of window token called an application window token, which uniquely identifies the application's top-level container window. The activity manager gives this token to both the application and the window manager, and the application sends the token to the window manager each time it wants to add a new window to the screen. This ensures secure interaction between the application and the window manager (by making it impossible to add windows on top of other applications), and also makes it easy for the activity manager to make direct requests to the window manager.
Check out here for dump. It seems there is a dump function in the library sqlite3.
If you're talking about ASP.NET MVC then you should have a controller method that returns the following:
return Redirect("http://www.google.com");
Otherwise we need more info on the error you're getting in the redirect. I'd step through to make sure the url isn't empty.
make
(or NMAKE
, or whatever flavour of make you are using) can be quite picky about the format of makefiles - check that you didn't actually edit the file in any way, e.g. changed line endings, spaces <-> tabs, etc.
On a current python version you have to use parenthesis, like so :
print ("If there was a birth every 7 seconds", X)
After adding JTextArea into JScrollPane here:
scroll = new JScrollPane(display);
You don't need to add it again into other container like you do:
middlePanel.add(display);
Just remove that last line of code and it will work fine. Like this:
middlePanel=new JPanel();
middlePanel.setBorder(new TitledBorder(new EtchedBorder(), "Display Area"));
// create the middle panel components
display = new JTextArea(16, 58);
display.setEditable(false); // set textArea non-editable
scroll = new JScrollPane(display);
scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
//Add Textarea in to middle panel
middlePanel.add(scroll);
JScrollPane is just another container that places scrollbars around your component when its needed and also has its own layout. All you need to do when you want to wrap anything into a scroll just pass it into JScrollPane constructor:
new JScrollPane( myComponent )
or set view like this:
JScrollPane pane = new JScrollPane ();
pane.getViewport ().setView ( myComponent );
Additional:
Here is fully working example since you still did not get it working:
public static void main ( String[] args )
{
JPanel middlePanel = new JPanel ();
middlePanel.setBorder ( new TitledBorder ( new EtchedBorder (), "Display Area" ) );
// create the middle panel components
JTextArea display = new JTextArea ( 16, 58 );
display.setEditable ( false ); // set textArea non-editable
JScrollPane scroll = new JScrollPane ( display );
scroll.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );
//Add Textarea in to middle panel
middlePanel.add ( scroll );
// My code
JFrame frame = new JFrame ();
frame.add ( middlePanel );
frame.pack ();
frame.setLocationRelativeTo ( null );
frame.setVisible ( true );
}
And here is what you get:
Stream: In laymen terms stream is data , most generic stream is binary representation of data.
Input Stream : If you are reading data from a file or any other source , stream used is input stream. In a simpler terms input stream acts as a channel to read data.
Output Stream : If you want to read and process data from a source (file etc) you first need to save the data , the mean to store data is output stream .
In my case I made small changes, when i search the value in tabelview select (didSelectRowAtIndexPath
) the cell its return the index of the cell so im get problem in move one viewControler to another.By using this method i found a solution to redirect to a new viewControler
let indexPath = tableView.indexPathForSelectedRow!
let currentCellValue = tableView.cellForRow(at: indexPath!)! as UITableViewCell
let textLabelText = currentCellValue.textLabel!.text
print(textLabelText)
The up-voted answer is valid.. and this information helped me quite a bit. I know this topic has been discussed before but I wanted to add some additional input. People are saying that you must "manually edit" the application.config file in the Users IISExpress/Config directory. This was a big issue for me because I wanted to distribute the configuration via Source control to various developers.
What I found is that you can automate the updating of this file using the "C:\Program Files\IIS Express\appcmd.exe" program. It took a while to find out the control parameters but Ill share my findings here. Essentially you can make a .bat file that runs both the NETSH command and the APPCMD.EXE (and perhaps swap out a host file if you like) to make host header configuration easy with IIS Express.
Your install bat file would look something like this:
netsh http add urlacl url=http://yourcustomdomain.com:80/ user=everyone
"C:\Program Files\IIS Express\appcmd.exe" set site "MyApp.Web" /+bindings.[protocol='http',bindingInformation='*:80:yourcustomdomain.com']
I also will make a "Uninstall" bat file that will clean up these bindings..(because often times Im just faking out DNS so that I can work on code that is host name sensitive)
netsh http delete urlacl url=http://yourcustomdomain.com:80/
"C:\Program Files\IIS Express\appcmd.exe" set site "MyApp.Web" /-bindings.[protocol='http',bindingInformation='*:80:yourcustomdomain.com']
I hope this information is helpful to someone.. It took me a bit to uncover.
I found that implementing a simple destroy() method to de-register any JDBC drivers works nicely.
/**
* Destroys the servlet cleanly by unloading JDBC drivers.
*
* @see javax.servlet.GenericServlet#destroy()
*/
public void destroy() {
String prefix = getClass().getSimpleName() +" destroy() ";
ServletContext ctx = getServletContext();
try {
Enumeration<Driver> drivers = DriverManager.getDrivers();
while(drivers.hasMoreElements()) {
DriverManager.deregisterDriver(drivers.nextElement());
}
} catch(Exception e) {
ctx.log(prefix + "Exception caught while deregistering JDBC drivers", e);
}
ctx.log(prefix + "complete");
}
If you only specify either the height or the width, but not both, most browsers will honor the aspect ratio.
Because you are working with an ASP.NET server control, you may consider executing logic on the server side prior to rendering to decide which (height or width) attribute you want to specify; that is, if you want a fixed height under one condition or a fixed width under another.
You can use this simple method after setting up your connection:
private void getAgentInfo(string key)//"key" is your search paramter inside database
{
con.Open();
string sqlquery = "SELECT * FROM TableName WHERE firstname = @fName";
SqlCommand command = new SqlCommand(sqlquery, con);
SqlDataReader sReader;
command.Parameters.Clear();
command.Parameters.AddWithValue("@fName", key);
sReader = command.ExecuteReader();
while (sReader.Read())
{
textBoxLastName.Text = sReader["Lastname"].ToString(); //SqlDataReader
//["LastName"] the name of your column you want to retrieve from DB
textBoxAge.Text = sReader["age"].ToString();
//["age"] another column you want to retrieve
}
con.Close();
}
Now you can pass the key to this method by your textBoxFirstName like:
getAgentInfo(textBoxFirstName.Text);
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'))
You should put your component between an enclosing tag, Which means:
// WRONG!
return (
<Comp1 />
<Comp2 />
)
Instead:
// Correct
return (
<div>
<Comp1 />
<Comp2 />
</div>
)
Edit: Per Joe Clay's comment about the Fragments API
// More Correct
return (
<React.Fragment>
<Comp1 />
<Comp2 />
</React.Fragment>
)
// Short syntax
return (
<>
<Comp1 />
<Comp2 />
</>
)
Not sure why no one mentioned this before -
echo mb_strimwidth("Hello World", 0, 10, "...");
// output: "Hello W..."

From the .NET blog Announcing .NET 2015 Preview: A New Era for .NET:
.NET Core has two major components. It includes a small runtime that is built from the same codebase as the .NET Framework CLR. The .NET Core runtime includes the same GC and JIT (RyuJIT), but doesn’t include features like Application Domains or Code Access Security. The runtime is delivered via NuGet, as part of the [ASP.NET Core] package.
.NET Core also includes the base class libraries. These libraries are largely the same code as the .NET Framework class libraries, but have been factored (removal of dependencies) to enable us to ship a smaller set of libraries. These libraries are shipped as System.* NuGet packages on NuGet.org.
And:
[ASP.NET Core] is the first workload that has adopted .NET Core. [ASP.NET Core] runs on both the .NET Framework and .NET Core. A key value of [ASP.NET Core] is that it can run on multiple versions of [.NET Core] on the same machine. Website A and website B can run on two different versions of .NET Core on the same machine, or they can use the same version.
In short: first, there was the Microsoft .NET Framework, which consists of a runtime that executes application and library code, and a nearly fully documented standard class library.
The runtime is the Common Language Runtime, which implements the Common Language Infrastructure, works with The JIT compiler to run the CIL (formerly MSIL) bytecode.
Microsoft's specification and implementation of .NET were, given its history and purpose, very Windows- and IIS-centered and "fat". There are variations with fewer libraries, namespaces and types, but few of them were useful for web or desktop development or are troublesome to port from a legal standpoint.
So in order to provide a non-Microsoft version of .NET, which could run on non-Windows machines, an alternative had to be developed. Not only the runtime has to be ported for that, but also the entire Framework Class Library to become well-adopted. On top of that, to be fully independent from Microsoft, a compiler for the most commonly used languages will be required.
Mono is one of few, if not the only alternative implementation of the runtime, which runs on various OSes besides Windows, almost all namespaces from the Framework Class Library as of .NET 4.5 and a VB and C# compiler.
Enter .NET Core: an open-source implementation of the runtime, and a minimal base class library. All additional functionality is delivered through NuGet packages, deploying the specific runtime, framework libraries and third-party packages with the application itself.
ASP.NET Core is a new version of MVC and WebAPI, bundled together with a thin HTTP server abstraction, that runs on the .NET Core runtime - but also on the .NET Framework.
You need at least 4 pennies, since you want to get 4 as a change, and you can do that only with pennies.
It isn't optimal to have more than 4 pennies. Instead of 4+x pennies, you can have 4 pennies and x nickels - they span at least the same range.
So you have exactly 4 pennies.
You need at least 1 nickel, since you want to get 5 as a change.
It isn't optimal to have more than 1 nickel. Instead of 1+x nickels, you can have 1 nickel and x dimes - they span at least the same range.
So you have exactly 1 nickel.
You need at least 2 dimes, since you want to get 20.
This means you have 4 pennies, 1 nickel and at least 2 dimes.
If you had less than 10 coins, you would have less than 3 quarters. But then the maximal possible change you could get using all coins is 4 + 5 + 20 + 50 = 79, not enough.
This means you have at least 10 coins. Thomas's answer shows that in fact if you have 4 pennies, 1 nickel, 2 dimes and 3 quarters, all is well.
Use Js2Py to translate JavaScript to Python, this is the only tool available :)
You can use replace:
df['y'] = df['y'].replace({'N/A': np.nan})
Also be aware of the inplace
parameter for replace
. You can do something like:
df.replace({'N/A': np.nan}, inplace=True)
This will replace all instances in the df without creating a copy.
Similarly, if you run into other types of unknown values such as empty string or None value:
df['y'] = df['y'].replace({'': np.nan})
df['y'] = df['y'].replace({None: np.nan})

There is no way to declare a global variable in Transact-SQL. However, if all you want your variables for is to be accessible across batches of a single script, you can use the SQLCMD tool or the SQLCMD mode of SSMS and define that tool/mode-specific variables like this:
:setvar myvar 10
and then use them like this:
$(myvar)
To use SSMS's SQLCMD mode:
Well you don't really have to worry about IE7 code not working in IE8 because IE8 has compatibility mode (it can render pages the same as IE7). But if you still want to target different versions of IE, a way that's been done for a while now is to either use conditional comments or begin your css rule with a * to target IE7 and below. Or you could pay attention to user agent on the servers and dish up a different CSS file based on that information.
Downloading Wget is not necessary; the .NET Framework has web client classes built in.
$wc = New-Object system.Net.WebClient;
$sms = Read-Host "Enter SMS text";
$sms = [System.Web.HttpUtility]::UrlEncode($sms);
$smsResult = $wc.downloadString("http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$sms&encoding=windows-1255")
As per François Noël's answer "For those who still can't make this work, make sure that the overflowed element is displayed before using the jQuery function."
I had been working in a bootstrap modal that I repeatedly bring up with account permissions in a div that overflows on the y dimension. My problem was, I was trying to use the jquery .scrollTop(0) function and it would not work no matter how I tried to do it. I had to setup an event for the modal that didn't reset the scrollbar until the modal had stopped animating. The code that finally worked for me is here:
$('#add-modal').on('shown.bs.modal', function (e) {
$('div.border').scrollTop(0);
});
You can not directly send an email with a HTML form. You can however send the form to your web server and then generate the email with a server side program written in e.g. PHP.
The other solution is to create a link as you did with the "mailto:". This will open the local email program from the user. And he/she can then send the pre-populated email.
When you decided how you wanted to do it you can ask another (more specific) question on this site. (Or you can search for a solution somewhere on the internet.)
<?php
$j=1;
array_reverse($skills_nav);
foreach ( $skills_nav as $skill ) {
$a = '<li><a href="#" data-filter=".'.$skill->slug.'">';
$a .= $skill->name;
$a .= '</a></li>';
echo $a;
echo "\n";
$j++;
}
?>
If your argument is positional (ie it doesn't have a "-" or a "--" prefix, just the argument, typically a file name) then you can use the nargs parameter to do this:
parser = argparse.ArgumentParser(description='Foo is a program that does things')
parser.add_argument('filename', nargs='?')
args = parser.parse_args()
if args.filename is not None:
print('The file name is {}'.format(args.filename))
else:
print('Oh well ; No args, no problems')

.phtml files tell the webserver that those are html files with dynamic content which is generated by the server... just like .php files in a browser behave. So, in productive usage you should experience no difference from .phtml to .php files.
To change the background color of all dialogs and pop-ups in your app, use colorBackgroundFloating
attribute.
<style name="MyApplicationTheme" parent="@style/Theme.AppCompat.NoActionBar">

<item name="colorBackgroundFloating">
@color/background</item>
<item name="android:colorBackgroundFloating" tools:targetApi="23">

Documentation:
If you push for example image to some API and want the result address(response) back you could do:
import requests
url = 'https://uguu.se/api.php?d=upload-tool'
data = {"name": filename}
files = {'file': open(full_file_path, 'rb')}
response = requests.post(url, data=data, files=files)
current_url = response.text
print(response.text)
For numerical data you have the solution. But it is categorical data, you said. Then life gets a bit more complicated...
Well, first : The amount of association between two categorical variables is not measured with a Spearman rank correlation, but with a Chi-square test for example. Which is logic actually. Ranking means there is some order in your data. Now tell me which is larger, yellow or red? I know, sometimes R does perform a spearman rank correlation on categorical data. If I code yellow 1 and red 2, R would consider red larger than yellow.
So, forget about Spearman for categorical data. I'll demonstrate the chisq-test and how to choose columns using combn(). But you would benefit from a bit more time with Agresti's book : http://www.amazon.com/Categorical-Analysis-Wiley-Probability-Statistics/dp/0471360937
set.seed(1234)
X <- rep(c("A","B"),20)
Y <- sample(c("C","D"),40,replace=T)
table(X,Y)
chisq.test(table(X,Y),correct=F)
# I don't use Yates continuity correction
#Let's make a matrix with tons of columns
Data <- as.data.frame(
matrix(
sample(letters[1:3],2000,replace=T),
ncol=25
)
)
# You want to select which columns to use
columns <- c(3,7,11,24)
vars <- names(Data)[columns]
# say you need to know which ones are associated with each other.
out <- apply( combn(columns,2),2,function(x){
chisq.test(table(Data[,x[1]],Data[,x[2]]),correct=F)$p.value
})
out <- cbind(as.data.frame(t(combn(vars,2))),out)
Then you should get :
> out
V1 V2 out
1 V3 V7 0.8116733
2 V3 V11 0.1096903
3 V3 V24 0.1653670
4 V7 V11 0.3629871
5 V7 V24 0.4947797
6 V11 V24 0.7259321
Where V1 and V2 indicate between which variables it goes, and "out" gives the p-value for association. Here all variables are independent. Which you would expect, as I created the data at random.
As mentioned in other answers, the exception is being thrown because each call to registerReceiver
is not being matched by exactly one call to unregisterReceiver
. Why not?
An Activity
does not always have a matching onDestroy
call for every onCreate
call. If the system runs out of memory, your app is evicted without calling onDestroy
.
The correct place to put a registerReceiver
call is in the onResume
call, and unregisterReceiver
in onPause
. This pair of calls is always matched. See the Activity lifecycle diagram for more details.
http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
Your code would change to:
SharedPreferences mPref
IntentFilter mFilter;
@Override
public void onCreate(){
super.onCreate();
mPref = PreferenceManager.getDefaultSharedPreferences(this);
mFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
filter.addAction(Intent.ACTION_POWER_CONNECTED);
filter.addAction(Intent.ACTION_POWER_DISCONNECTED);
}
@Override
public void onResume() {
registerReceiver(batteryNotifyReceiver,mFilter);
mPref.registerOnSharedPreferenceChangeListener(this);
}
@Override
public void onPause(){
unregisterReceiver(batteryNotifyReceiver, mFilter);
mPref.unregisterOnSharedPreferenceChangeListener(this);
}
You could implement a JavaScript block which contains a function with your needs.
<div style="position: absolute; left: 10px; top: 40px;">
<img src="logg.png" width="114" height="38" onclick="DoSomething();" />
</div>
array_walk($v, function(&$value, $key) {
echo $key . '--'. $value;
});

Nothing suggested above worked for me (including the NODE_PATH variable). I created a sym link of "node_modules" from my local folder to the global AppData(eg below) and it worked like charm.

There's also the MySQL FIELD
function.
If you want complete sorting for all possible values:
SELECT id, name, priority
FROM mytable
ORDER BY FIELD(name, "core", "board", "other")
If you only care that "core" is first and the other values don't matter:
SELECT id, name, priority
FROM mytable
ORDER BY FIELD(name, "core") DESC
If you want to sort by "core" first, and the other fields in normal sort order:
SELECT id, name, priority
FROM mytable
ORDER BY FIELD(name, "core") DESC, priority
There are some caveats here, though:
First, I'm pretty sure this is mysql-only functionality - the question is tagged mysql, but you never know.
Second, pay attention to how FIELD()
works: it returns the one-based index of the value - in the case of FIELD(priority, "core")
, it'll return 1 if "core" is the value. If the value of the field is not in the list, it returns zero. This is why DESC
is necessary unless you specify all possible values.
Using the QuantiPhy package is an option. Normally QuantiPhy is used when working with numbers with units and SI scale factors, but it has a variety of nice number formatting options.
>>> from quantiphy import Quantity
>>> cases = '3 3. 3.0 3.1 3.14 3.140 3.14000'.split()
>>> for case in cases:
... q = Quantity(case)
... print(f'{case:>7} -> {q:p}')
3 -> 3
3. -> 3
3.0 -> 3
3.1 -> 3.1
3.14 -> 3.14
3.140 -> 3.14
3.14000 -> 3.14
And it will not use e-notation in this situation:
>>> cases = '3.14e-9 3.14 3.14e9'.split()
>>> for case in cases:
... q = Quantity(case)
... print(f'{case:>7} -> {q:,p}')
3.14e-9 -> 0
3.14 -> 3.14
3.14e9 -> 3,140,000,000
An alternative you might prefer is to use SI scale factors, perhaps with units.
>>> cases = '3e-9 3.14e-9 3 3.14 3e9 3.14e9'.split()
>>> for case in cases:
... q = Quantity(case, 'm')
... print(f'{case:>7} -> {q}')
3e-9 -> 3 nm
3.14e-9 -> 3.14 nm
3 -> 3 m
3.14 -> 3.14 m
3e9 -> 3 Gm
3.14e9 -> 3.14 Gm
$(this).find('option:selected').text();
This is not as easy as it seems, some core library functions don't work when only str is overwritten (checked with Python 2.7), see this thread for examples How to make a class JSON serializable Also, try this
import json
class A(unicode):
def __str__(self):
return 'a'
def __unicode__(self):
return u'a'
def __repr__(self):
return 'a'
a = A()
json.dumps(a)
produces
'""'
and not
'"a"'
as would be expected.
EDIT: answering mchicago's comment:
unicode does not have any attributes -- it is an immutable string, the value of which is hidden and not available from high-level Python code. The json
module uses re
for generating the string representation which seems to have access to this internal attribute. Here's a simple example to justify this:
b = A('b')
print b
produces
'a'
while
json.dumps({'b': b})
produces
{"b": "b"}
so you see that the internal representation is used by some native libraries, probably for performance reasons.
See also this for more details: http://www.laurentluce.com/posts/python-string-objects-implementation/
Well for me the problem got resolved by adding the jars in my APACHE/TOMCAT/lib folder ! .
I was able to solve this problem by executing this statement
sudo dpkg-reconfigure mysql-server-5.5
Which will change the root password.
If you want to change the range to [0, 1], make sure the output data type is float
.
image = cv2.imread("lenacolor512.tiff", cv2.IMREAD_COLOR) # uint8 image
norm_image = cv2.normalize(image, None, alpha=0, beta=1, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_32F)
The column in the database is probably a DECIMAL
. You should process it as a BigInteger
, not an Integer
, otherwise you are losing digits. Or else change the column to int
.
To change the integrated terminal on Windows, you just need to change the terminal.integrated.shell.windows
line:
"terminal.integrated.shell.windows": "C:\\Bin\\Cmder\\Cmder.exe"
setting to the User Settings document on the right if it's not already there. This is so you aren't editing the Default Setting directly, but instead adding to it.You can then access it with keys Ctrl+backtick by default.
For clarity since some other comments are incorrect, when using System.Timers
setting Enabled to true will reset the elapsed time. I just tested the behavior with the below:
Timer countDown= new Timer(3000);
Main()
{
TextBox.TextDidChange += TextBox_TextDidChange;
countdown.Elapsed += CountDown_Elapsed;
}
void TextBox_TextDidChange(Object sender, EventArgs e)
{
countdown.Enabled = true;
}
void CountDown_Elapsed(object sender, EventArgs e)
{
System.Console.WriteLine("Elapsed");
}
I would input text to the text box repeatedly and the timer would only run 3 seconds after the last keystroke. It's hinted at in the docs as well, as you'll see: calling Timers.Start()
simply sets Enabled to true.
And to be sure, which I should've just went straight to from the beginning, you'll see in the .NET reference source that if enabling an already Enabled timer it calls the private UpdateTimer()
method, which internally calls Change()
.

You can use lodash's method, it works for string, number and boolean type
_.compact([0, 1, false, 2, '', 3]);

React (or JSX) doesn't support variable interpolation inside an attribute value, but you can put any JS expression inside curly braces as the entire attribute value, so this works:
<img className="image" src={"images/" + this.props.image} />
Inner joins require that a record with a related ID exist in the joined table.
Outer joins will return records for the left side even if nothing exists for the right side.
For instance, you have an Orders and an OrderDetails table. They are related by an "OrderID".
Orders
OrderDetails
The request
SELECT Orders.OrderID, Orders.CustomerName
FROM Orders
INNER JOIN OrderDetails
ON Orders.OrderID = OrderDetails.OrderID
will only return Orders that also have something in the OrderDetails table.
If you change it to OUTER LEFT JOIN
SELECT Orders.OrderID, Orders.CustomerName
FROM Orders
LEFT JOIN OrderDetails
ON Orders.OrderID = OrderDetails.OrderID
then it will return records from the Orders table even if they have no OrderDetails records.
You can use this to find Orders that do not have any OrderDetails indicating a possible orphaned order by adding a where clause like WHERE OrderDetails.OrderID IS NULL
.
While these answers are all correct, resolving the problem is often more difficult. It's generally the result of two mildly different versions of the same dependency on the classpath, and is almost always caused by either a different superclass than was originally compiled against being on the classpath or some import of the transitive closure being different, but generally at class instantiation and constructor invocation. (After successful class loading and ctor invocation, you'll get NoSuchMethodException
or whatnot.)
If the behavior appears random, it's likely the result of a multithreaded program classloading different transitive dependencies based on what code got hit first.
To resolve these, try launching the VM with -verbose
as an argument, then look at the classes that were being loaded when the exception occurs. You should see some surprising information. For instance, having multiple copies of the same dependency and versions you never expected or would have accepted if you knew they were being included.
Resolving duplicate jars with Maven is best done with a combination of the maven-dependency-plugin and maven-enforcer-plugin under Maven (or SBT's Dependency Graph Plugin, then adding those jars to a section of your top-level POM or as imported dependency elements in SBT (to remove those dependencies).
Good luck!
In Loops, I always prefer to use the Cells
class, using the R1C1 reference method, like this:
Cells(rr, col).Formula = ...
This allows me to quickly and easily loop over a Range of cells easily:
Dim r As Long
Dim c As Long
c = GetTargetColumn() ' Or you could just set this manually, like: c = 1
With Sheet1 ' <-- You should always qualify a range with a sheet!
For r = 1 To 10 ' Or 1 To (Ubound(MyListOfStuff) + 1)
' Here we're looping over all the cells in rows 1 to 10, in Column "c"
.Cells(r, c).Value = MyListOfStuff(r)
'---- or ----
'...to easily copy from one place to another (even with an offset of rows and columns)
.Cells(r, c).Value = Sheet2.Cells(r + 3, 17).Value
Next r
End With

The documentation for SmtpClient
, the class used in this answer, now reads, 'Obsolete("SmtpClient and its network of types are poorly designed, we strongly recommend you use https://github.com/jstedfast/MailKit and https://github.com/jstedfast/MimeKit instead")'.
Source: https://www.infoq.com/news/2017/04/MailKit-MimeKit-Official
Original Answer:
Using the MailDefinition class is the wrong approach. Yes, it's handy, but it's also primitive and depends on web UI controls--that doesn't make sense for something that is typically a server-side task.
The approach presented below is based on MSDN documentation and Qureshi's post on CodeProject.com.
NOTE: This example extracts the HTML file, images, and attachments from embedded resources, but using other alternatives to get streams for these elements are fine, e.g. hard-coded strings, local files, and so on.
Stream htmlStream = null;
Stream imageStream = null;
Stream fileStream = null;
try
{
// Create the message.
var from = new MailAddress(FROM_EMAIL, FROM_NAME);
var to = new MailAddress(TO_EMAIL, TO_NAME);
var msg = new MailMessage(from, to);
msg.Subject = SUBJECT;
msg.SubjectEncoding = Encoding.UTF8;
// Get the HTML from an embedded resource.
var assembly = Assembly.GetExecutingAssembly();
htmlStream = assembly.GetManifestResourceStream(HTML_RESOURCE_PATH);
// Perform replacements on the HTML file (if you're using it as a template).
var reader = new StreamReader(htmlStream);
var body = reader
.ReadToEnd()
.Replace("%TEMPLATE_TOKEN1%", TOKEN1_VALUE)
.Replace("%TEMPLATE_TOKEN2%", TOKEN2_VALUE); // and so on...
// Create an alternate view and add it to the email.
var altView = AlternateView.CreateAlternateViewFromString(body, null, MediaTypeNames.Text.Html);
msg.AlternateViews.Add(altView);
// Get the image from an embedded resource. The <img> tag in the HTML is:
// <img src="pid:IMAGE.PNG">
imageStream = assembly.GetManifestResourceStream(IMAGE_RESOURCE_PATH);
var linkedImage = new LinkedResource(imageStream, "image/png");
linkedImage.ContentId = "IMAGE.PNG";
altView.LinkedResources.Add(linkedImage);
// Get the attachment from an embedded resource.
fileStream = assembly.GetManifestResourceStream(FILE_RESOURCE_PATH);
var file = new Attachment(fileStream, MediaTypeNames.Application.Pdf);
file.Name = "FILE.PDF";
msg.Attachments.Add(file);
// Send the email
var client = new SmtpClient(...);
client.Credentials = new NetworkCredential(...);
client.Send(msg);
}
finally
{
if (fileStream != null) fileStream.Dispose();
if (imageStream != null) imageStream.Dispose();
if (htmlStream != null) htmlStream.Dispose();
}
MATLAB, as mentioned by others, is great at matrix manipulation, and was originally built as an extension of the well-known BLAS and LAPACK libraries used for linear algebra. It interfaces well with other languages like Java, and is well favored by engineering and scientific companies for its well developed and documented libraries. From what I know of Python and NumPy, while they share many of the fundamental capabilities of MATLAB, they don't have the full breadth and depth of capabilities with their libraries.
Personally, I use MATLAB because that's what I learned in my internship, that's what I used in grad school, and that's what I used in my first job. I don't have anything against Python (or any other language). It's just what I'm used too.
Also, there is another free version in addition to scilab mentioned by @Jim C from gnu called Octave.
In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*')
. See here:
SQL Function
Description
REGEXP_LIKE
This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.
...
REGEXP_REPLACE
This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.
...
REGEXP_INSTR
This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.
...
REGEXP_SUBSTR
This function returns the actual substring matching the regular expression pattern you specify.
(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$'
for a beginning (^
) and end ($
) match, e.g.: '^regex.*$'
.)
It should be,
*/15 * * * * your_command_or_whatever
It's possible to pass multiple parameters as a single model as vijay suggested. This works for GET when you use the FromUri parameter attribute. This tells WebAPI to fill the model from the query parameters.
The result is a cleaner controller action with just a single parameter. For more information see: http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api
public class BooksController : ApiController
{
// GET /api/books?author=tolk&title=lord&isbn=91&somethingelse=ABC&date=1970-01-01
public string GetFindBooks([FromUri]BookQuery query)
{
// ...
}
}
public class BookQuery
{
public string Author { get; set; }
public string Title { get; set; }
public string ISBN { get; set; }
public string SomethingElse { get; set; }
public DateTime? Date { get; set; }
}
It even supports multiple parameters, as long as the properties don't conflict.
// GET /api/books?author=tolk&title=lord&isbn=91&somethingelse=ABC&date=1970-01-01
public string GetFindBooks([FromUri]BookQuery query, [FromUri]Paging paging)
{
// ...
}
public class Paging
{
public string Sort { get; set; }
public int Skip { get; set; }
public int Take { get; set; }
}
Update:
In order to ensure the values are optional make sure to use reference types or nullables (ex. int?) for the models properties.
Yes, you can use the ALTER TABLE t AUTO_INCREMENT = 42
statement. However, you need to be aware that this will cause the rebuilding of your entire table, at least with InnoDB and certain MySQL versions. If you have an already existing dataset with millions of rows, it could take a very long time to complete.
In my experience, it's better to do the following:
BEGIN WORK;
-- You may also need to add other mandatory columns and values
INSERT INTO t (id) VALUES (42);
ROLLBACK;
In this way, even if you're rolling back the transaction, MySQL will keep the auto-increment value, and the change will be applied instantly.
You can verify this by issuing a SHOW CREATE TABLE t
statement. You should see:
> SHOW CREATE TABLE t \G
*************************** 1. row ***************************
Table: t
Create Table: CREATE TABLE `t` (
...
) ENGINE=InnoDB AUTO_INCREMENT=43 ...
The key difference is that a repository handles the access to the aggregate roots in a an aggregate, while DAO handles the access to entities. Therefore, it's common that a repository delegates the actual persistence of the aggregate roots to a DAO. Additionally, as the aggregate root must handle the access of the other entities, then it may need to delegate this access to other DAOs.
This solution worked for me: Right click the Project and select edit and find the following code as shown below in the picture.
change the <UseIIS>True</UseIIS> to <UseIIS>False</UseIIS>
OR
change the <IISUrl>http://example.com/</IISUrl> to <IISUrl>http://localhost/</IISUrl>
Just want to sum up, there might be 4 ways.
or open a new table view control with a check mark:
Hope this helps.

Two options: 1, add css inline like style="background:black" Or 2. In the head include the css as a style tag block.
I've made basic black launch screens that will make the app scale properly on the iPhone 6 and iPhone 6+:
If you already have a LaunchImage in your .xcassett, open it, switch to the third tab in the right menu in Xcode and tick the iOS 8.0 iPhone images to add them to the existing set. Then drag the images over:
For people who want to use another diff tool not listed in git, say with nvim
. here is what I ended up using:
git config --global alias.d difftool -x <tool name>
In my case, I set <tool name>
to nvim -d
and invoke the diff command with
git d <file>
This is more of an xpath question, but like this, assuming the context is the parent element:
<xsl:value-of select="name/@attribute1" />
When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.
But there are more important differences on the receiving side of things. When the receiver does a recv
(or read
) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.
Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.
I had a similar issue with Windows server 2012, installing the feature "Application Server" in the server manager fixed the issue.
For someone who want to use onchange event directly on file input, set onchange="somefunction()
, example code from the link:
<html>
<body>
<script language="JavaScript">
function inform(){
document.form1.msg.value = "Filename has been changed";
}
</script>
<form name="form1">
Please choose a file.
<input type="file" name="uploadbox" size="35" onChange='inform()'>
<br><br>
Message:
<input type="text" name="msg" size="40">
</form>
</body>
</html>
You are iterating through an undefined
value, ie, com
property of the Array's object, you should iterate through the array itself:
$.each(obj, function(key,value) {
// here `value` refers to the objects
});
Also note that jQuery intelligently tries to parse the sent JSON, probably you don't need to parse the response. If you are using $.ajax()
, you can set the dataType
to json
which tells jQuery parse the JSON for you.
If it still doesn't work, check the browser's console for troubleshooting.
You can also use create_function to create a function as a variable and pass it around. Though, I like the feeling of anonymous functions better. Go zombat.
It is late answer but can be useful for others. In view use ViewBag as following:
@Html.Raw("<script>" + ViewBag.DynamicScripts + "</script>")
Then from controller set this ViewBag as follows:
ViewBag.DynamicScripts = "javascriptFun()";
This will execute JavaScript function. But this function would not execute if it is ajax call. To call JavaScript function from ajax call back, return two values from controller and write success function in ajax callback as following:
$.ajax({
type: "POST",
url: "/Controller/Action", // the URL of the controller action method
data: null, // optional data
success: function(result) {
// do something with result
},
success: function(result, para) {
if(para == 'something'){
//run JavaScript function
}
},
error : function(req, status, error) {
// do something with error
}
});
from controller you can return two values as following:
return Json(new { json = jr.Data, value2 = "value2" });
In my case, after I delete all certification created by Xcode and downloaded. Let xcode 8.1 manage certification of app, It works well!!! Hope this can help someone.
I solved this problem by set my go env GO111MODULE to off
go env -w GO111MODULE=off
Remove the z-index value.
I would also recommend this approach.
HTML:
<header class="main-header" role="banner">
<img src="mybannerimage.gif" alt="Banner Image"/>
</header>
CSS:
.main-header {
text-align: center;
}
This will center your image with out stretching it out. You can adjust the padding as needed to give it some space around your image. Since this is at the top of your page you don't need to force it there with position absolute unless you want your other elements to go underneath it. In that case you'd probably want position:fixed; anyway.
You need to link with the math library:
gcc -o sphere sphere.c -lm
The error you are seeing: error: ld returned 1 exit status
is from the linker ld
(part of gcc that combines the object files) because it is unable to find where the function pow
is defined.
Including math.h
brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a
. You need to link your program with this library so that the calls to functions like pow() are resolved.
Here is what I'm doing:
git clone repo /tmp/folder
cp -rf /tmp/folder/.git /dest/folder/
cd /dest/folder
git checkout -f master
Worked on 08/08/2018 and on DRF version 3.8.2:
class ItemSerializer(serializers.ModelSerializer):
category_name = serializers.ReadOnlyField(source='category.name')
class Meta:
model = Item
read_only_fields = ('id', 'category_name')
fields = ('id', 'category_name', 'name',)
Using the Meta read_only_fields
we can declare exactly which fields should be read_only. Then we need to declare the foreign
field on the Meta fields
(better be explicit as the mantra goes: zen of python).
Another method:
SELECT *
FROM (
SELECT * FROM table_name
ORDER BY date ASC, time ASC
) AS sub
GROUP BY name
GROUP BY groups on the first matching result it hits. If that first matching hit happens to be the one you want then everything should work as expected.
I prefer this method as the subquery makes logical sense rather than peppering it with other conditions.
To make sure you have the application's path (and not just the current directory), use this:
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.getcurrentprocess.aspx
Now you have a Process
object that represents the process that is running.
Then use Process.MainModule.FileName
:
http://msdn.microsoft.com/en-us/library/system.diagnostics.processmodule.filename.aspx
Finally, use Path.GetDirectoryName
to get the folder containing the .exe:
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname.aspx
So this is what you want:
string folder = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName) + @"\Archive\";
string filter = "*.zip";
string[] files = Directory.GetFiles(folder, filter);
(Notice that "\Archive\"
from your question is now @"\Archive\"
: you need the @ so that the \
backslashes aren't interpreted as the start of an escape sequence)
Hope that helps!

This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)

There are several places colon is used in Java code:
1) Jump-out label (Tutorial):
label: for (int i = 0; i < x; i++) {
for (int j = 0; j < i; j++) {
if (something(i, j)) break label; // jumps out of the i loop
}
}
// i.e. jumps to here
2) Ternary condition (Tutorial):
int a = (b < 4)? 7: 8; // if b < 4, set a to 7, else set a to 8
3) For-each loop (Tutorial):
String[] ss = {"hi", "there"}
for (String s: ss) {
print(s); // output "hi" , and "there" on the next iteration
}
4) Assertion (Guide):
int a = factorial(b);
assert a >= 0: "factorial may not be less than 0"; // throws an AssertionError with the message if the condition evaluates to false
5) Case in switch statement (Tutorial):
switch (type) {
case WHITESPACE:
case RETURN:

case NUMBER:
print("got number: " + value);
break;
default:
print("syntax error");
}
6) Method references (Tutorial)

There is a very useful module for formatting text (bold, underline, colors..) in Python. It uses curses
lib but it's very straight-forward to use.
An example:
from terminal import render
print render('%(BG_YELLOW)s%(RED)s%(BOLD)sHey this is a test%(NORMAL)s')
print render('%(BG_GREEN)s%(RED)s%(UNDERLINE)sAnother test%(NORMAL)s')
I wrote a simple module named colors.py to make this a little more pythonic:
import colors
with colors.pretty_output(colors.BOLD, colors.FG_RED) as out:
out.write("This is a bold red text")
with colors.pretty_output(colors.BG_GREEN) as out:
out.write("This output have a green background but you " +
colors.BOLD + colors.FG_RED + "can" + colors.END + " mix styles")
you can use
parent.style.setProperty("--padding-top", (height*100/width).toFixed(2)+"%");
in css
el:after{
....
padding-top:var(--padding-top, 0px);
}
print $input."<hr>".ereg_replace('/&/', ':::', $input);
becomes
print $input."<hr>".preg_replace('/&/', ':::', $input);
More example :
$mytext = ereg_replace('[^A-Za-z0-9_]', '', $mytext );
is changed to
$mytext = preg_replace('/[^A-Za-z0-9_]/', '', $mytext );
JSONP stands for “JSON with Padding” and it is a workaround for loading data from different domains. It loads the script into the head of the DOM and thus you can access the information as if it were loaded on your own domain, thus by-passing the cross domain issue.
jsonCallback(
{
"sites":
[
{
"siteName": "JQUERY4U",
"domainName": "http://www.jquery4u.com",
"description": "#1 jQuery Blog for your Daily News, Plugins, Tuts/Tips & Code Snippets."
},
{
"siteName": "BLOGOOLA",
"domainName": "http://www.blogoola.com",
"description": "Expose your blog to millions and increase your audience."
},
{
"siteName": "PHPSCRIPTS4U",
"domainName": "http://www.phpscripts4u.com",
"description": "The Blog of Enthusiastic PHP Scripters"
}
]
});
(function($) {
var url = 'http://www.jquery4u.com/scripts/jquery4u-sites.json?callback=?';
$.ajax({
type: 'GET',
url: url,
async: false,
jsonpCallback: 'jsonCallback',
contentType: "application/json",
dataType: 'jsonp',
success: function(json) {
console.dir(json.sites);
},
error: function(e) {
console.log(e.message);
}
});
})(jQuery);
Now we can request the JSON via AJAX using JSONP and the callback function we created around the JSON content. The output should be the JSON as an object which we can then use the data for whatever we want without restrictions.
You do not even need lists if your "number" values are all of the same mode. If I take Dirk Eddelbuettel's example:
> foo <- c(12, 22, 33)
> names(foo) <- c("tic", "tac", "toe")
> foo
tic tac toe
12 22 33
> names(foo)
[1] "tic" "tac" "toe"
Lists are only required if your values are either of mixed mode (for example characters and numbers) or vectors.
For both lists and vectors, an individual element can be subsetted by name:
> foo["tac"]
tac
22
Or for a list:
> foo[["tac"]]
[1] 22
LatLng hello = new LatLng(X, Y); // whereX & Y are coordinates

mMap.moveCamera(CameraUpdateFactory.newLatLng(hello));
Because line magics are only supported by the IPython command line not by Python cl, use: 'exec(%matplotlib inline)'
instead of %matplotlib inline
==========Advise==========
@martin clayton Answer is correct, But this is an advise only.
Please avoid the use of ambiguous variable in the stored procedure.
Example :
SELECT Id, dateCreated
INTO id, datecreated
FROM products
WHERE pName = iName
The above example will cause an error (null value error)
Example give below is correct. I hope this make sense.
Example :
SELECT Id, dateCreated
INTO val_id, val_datecreated
FROM products
WHERE pName = iName
You can also make them unambiguous by referencing the table, like:
[ Credit : maganap ]
SELECT p.Id, p.dateCreated INTO id, datecreated FROM products p
WHERE pName = iName
The easiest way that I know to achieve that is through Kotlin Android Extensions.
On your app/build.gradle
apply plugin: 'kotlin-android-extensions'
If your button is called 'btnAdd', then on your fragment or activity import the following:
import kotlinx.android.synthetic.main.fragment_transactions.btnAdd
override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
btnAdd.setOnClickListener {
Toast.makeText(context , "Done", 10).show()
}
}
This seems more straightforward using data.table
as it performs the sort while setting the key.
So, if I were to get the top 3 records in sort (ascending order), then,
require(data.table)
d <- data.table(mtcars, key="cyl")
d[, head(.SD, 3), by=cyl]
does it.
And if you want the descending order
d[, tail(.SD, 3), by=cyl] # Thanks @MatthewDowle
Edit: To sort out ties using mpg
column:
d <- data.table(mtcars, key="cyl")
d.out <- d[, .SD[mpg %in% head(sort(unique(mpg)), 3)], by=cyl]
# cyl mpg disp hp drat wt qsec vs am gear carb rank
# 1: 4 22.8 108.0 93 3.85 2.320 18.61 1 1 4 1 11
# 2: 4 22.8 140.8 95 3.92 3.150 22.90 1 0 4 2 1
# 3: 4 21.5 120.1 97 3.70 2.465 20.01 1 0 3 1 8
# 4: 4 21.4 121.0 109 4.11 2.780 18.60 1 1 4 2 6
# 5: 6 18.1 225.0 105 2.76 3.460 20.22 1 0 3 1 7
# 6: 6 19.2 167.6 123 3.92 3.440 18.30 1 0 4 4 1
# 7: 6 17.8 167.6 123 3.92 3.440 18.90 1 0 4 4 2
# 8: 8 14.3 360.0 245 3.21 3.570 15.84 0 0 3 4 7
# 9: 8 10.4 472.0 205 2.93 5.250 17.98 0 0 3 4 14
# 10: 8 10.4 460.0 215 3.00 5.424 17.82 0 0 3 4 5
# 11: 8 13.3 350.0 245 3.73 3.840 15.41 0 0 3 4 3
# and for last N elements, of course it is straightforward
d.out <- d[, .SD[mpg %in% tail(sort(unique(mpg)), 3)], by=cyl]
After I tried algirdas' solution, my Windows crashed (Win 7 Pro 64bit) so I decided to try a different solution:
Run
(Win+R)cmd /K chcp 65001
You will get mostly what you want. To start it from the taskbar or anywhere else, make a shortcut (you can name it cmd.unicode.exe
or whatever you like) and change its Target
to C:\Windows\System32\cmd.exe /K chcp 65001
.
Actually, there are several ways to create objects in JavaScript. When you just want to create an object there's no benefit of creating "constructor-based" objects using "new" operator. It's same as creating an object using "object literal" syntax. But "constructor-based" objects created with "new" operator comes to incredible use when you are thinking about "prototypal inheritance". You cannot maintain inheritance chain with objects created with literal syntax. But you can create a constructor function, attach properties and methods to its prototype. Then if you assign this constructor function to any variable using "new" operator, it will return an object which will have access to all of the methods and properties attached with the prototype of that constructor function.
Here is an example of creating an object using constructor function (see code explanation at the bottom):
function Person(firstname, lastname) {
this.firstname = firstname;
this.lastname = lastname;
}
Person.prototype.fullname = function() {
console.log(this.firstname + ' ' + this.lastname);
}
var zubaer = new Person('Zubaer', 'Ahammed');
var john = new Person('John', 'Doe');
zubaer.fullname();
john.fullname();
Now, you can create as many objects as you want by instantiating Person construction function and all of them will inherit fullname() from it.
Note: "this" keyword will refer to an empty object within a constructor function and whenever you create a new object from Person using "new" operator it will automatically return an object containing all of the properties and methods attached with the "this" keyword. And these object will for sure inherit the methods and properties attached with the prototype of the Person constructor function (which is the main advantage of this approach).
By the way, if you wanted to obtain the same functionality with "object literal" syntax, you would have to create fullname() on all of the objects like below:
var zubaer = {
firstname: 'Zubaer',
lastname: 'Ahammed',
fullname: function() {
console.log(this.firstname + ' ' + this.lastname);
}
};
var john= {
firstname: 'John',
lastname: 'Doe',
fullname: function() {
console.log(this.firstname + ' ' + this.lastname);
}
};
zubaer.fullname();
john.fullname();
At last, if you now ask why should I use constructor function approach instead of object literal approach:
*** Prototypal inheritance allows a simple chain of inheritance which can be immensely useful and powerful.
*** It saves memory by inheriting common methods and properties defined in constructor functions prototype. Otherwise, you would have to copy them over and over again in all of the objects.
I hope this makes sense.
ls -l --block-size=M
will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB. If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.
Or
ls -lah
-h When used with the -l option, use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number of digits to three or less using base 2 for sizes.
man ls
Here is another approach using getter and setter functions for the model.
@Component({
selector: 'input-language',
template: `
…
<input
type="text"
placeholder="Language"
[(ngModel)]="query"
/>
`,
})
export class InputLanguageComponent {
set query(value) {
this._query = value;
console.log('query set to :', value)
}
get query() {
return this._query;
}
}
If the bucket is quite big there is a command called s4cmd
which makes parallel connections and improves the download time:
To install it on Debian like
apt install s4cmd
If you have pip:
pip install s4cmd
It will read the ~/.s3cfg
file if present (if not install s3cmd
and run s3cmd --configure
) or you can specify --access-key=ACCESS_KEY --secret-key=SECRET_KEY
on the command.
The cli is similar to s3cmd
. In your case a sync
is recommended as you can cancel the download and start it again without having to re-downloaded the files.
s4cmd [--access-key=ACCESS_KEY --secret-key=SECRET_KEY] sync s3://<your-bucket> /some/local/dir
Be careful if you download a lot of data (>1TB) this may impact your bill, calculate first which will be the cost
// let timeObject = new Date();
// let milliseconds= 10 * 1000; // 10 seconds = 10000 milliseconds
timeObject = new Date(timeObject.getTime() + milliseconds);
This would be the correct implementation, although I don't see anything you need to dispose in the code you posted. You only need to implement IDisposable
when:
Nothing in the code you posted needs to be disposed.
public class User : IDisposable
{
public int id { get; protected set; }
public string name { get; protected set; }
public string pass { get; protected set; }
public User(int userID)
{
id = userID;
}
public User(string Username, string Password)
{
name = Username;
pass = Password;
}
// Other functions go here...
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (disposing)
{
// free managed resources
}
// free native resources if there are any.
}
}
<context:component-scan base-package="" />
tells Spring to scan those packages for Annotations.
<mvc:annotation-driven>
registers a RequestMappingHanderMapping, a RequestMappingHandlerAdapter, and an ExceptionHandlerExceptionResolver to support the annotated controller methods like @RequestMapping, @ExceptionHandler, etc. that come with MVC.
This also enables a ConversionService that supports Annotation driven formatting of outputs as well as Annotation driven validation for inputs. It also enables support for @ResponseBody which you can use to return JSON data.
You can accomplish the same things using Java-based Configuration using @ComponentScan(basePackages={"...", "..."} and @EnableWebMvc in a @Configuration class.
Check out the 3.1 documentation to learn more.
http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/mvc.html#mvc-config
This problem can be caused by undue manipulation of the enabled cipher suites at the client or the server, but I suspect the most common cause is the server not having a private key and certificate at all.
NB:
ssl.setEnabledCipherSuites(sc.getServerSocketFactory().getSupportedCipherSuites());
Get rid of this line. Your server is insecure enough already with that insecure TrustManager
. Then run your server with -Djavax.net.debug=SSL,handshake,
try one connect, and post the resulting output here.
First step would be making the function object, then applying it. If you want a matrix object that has the same number of rows, you can predefine it and use the object[] form as illustrated (otherwise the returned value will be simplified to a vector):
bvnormdens <- function(x=c(0,0),mu=c(0,0), sigma=c(1,1), rho=0){
exp(-1/(2*(1-rho^2))*(x[1]^2/sigma[1]^2+
x[2]^2/sigma[2]^2-
2*rho*x[1]*x[2]/(sigma[1]*sigma[2]))) *
1/(2*pi*sigma[1]*sigma[2]*sqrt(1-rho^2))
}
out=rbind(c(1,2),c(3,4),c(5,6));
bvout<-matrix(NA, ncol=1, nrow=3)
bvout[] <-apply(out, 1, bvnormdens)
bvout
[,1]
[1,] 1.306423e-02
[2,] 5.931153e-07
[3,] 9.033134e-15
If you wanted to use other than your default parameters then the call should include named arguments after the function:
bvout[] <-apply(out, 1, FUN=bvnormdens, mu=c(-1,1), rho=0.6)
apply() can also be used on higher dimensional arrays and the MARGIN argument can be a vector as well as a single integer.
Use Basic Authorization And Json Parameters.
using (HttpClient client = new HttpClient())
{
var request_json = "your json string";
var content = new StringContent(request_json, Encoding.UTF8, "application/json");
var authenticationBytes = Encoding.ASCII.GetBytes("YourUsername:YourPassword");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(authenticationBytes));
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var result = await client.PostAsync("YourURL", content);
var result_string = await result.Content.ReadAsStringAsync();
}
what about just have the option number:
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s;
int op;
cin >> s >> op;
switch (op) {
case 1: break;
case 2: break;
default:
}
return 0;
}
As @kgr mentioned, MySQL 8.0.11 made some changes to the authentication method.
I've opened a phpMyAdmin bug report about this: https://github.com/phpmyadmin/phpmyadmin/issues/14220.
MySQL 8.0.4-rc was working fine for me, and I kind of think it's ridiculous for MySQL to make such a change in a patch level release.
The behavior of StringEscapeUtils.escapeXml() has changed from Commons Lang 2.5 to 3.0. It now no longer escapes Unicode characters greater than 0x7f.
This is a good thing, the old method was to be a bit to eager to escape entities that could just be inserted into a utf8 document.
The new escapers to be included in Google Guava 11.0 also seem promising: http://code.google.com/p/guava-libraries/issues/detail?id=799
I was able to install libc6 2.17
in Debian Wheezy
by editing the recommendations in perror's answer:
IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1.
Then you can stop x (slim
) with sudo /etc/init.d/slim stop
(replace slim with mdm
or lightdm
or whatever)
Add the following line to the file /etc/apt/sources.list
:
deb http://ftp.debian.org/debian experimental main
Should be changed to:
deb http://ftp.debian.org/debian sid main
Then follow the rest of perror's post:
Update your package database:
apt-get update
Install the eglibc
package:
apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg
IMPORTANT
After done updating libc6
, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main
), or else you risk upgrading your whole distro to sid.
Hope this helps. It took me a while to figure out.
Or more simple without having to name the element (with 'button' element):
<button onclick="toggleLog(this)">Stop logs</button>
and script :
var bWriteLog = true;
function toggleLog(elt) {
bWriteLog = !bWriteLog;
elt.innerHTML = bWriteLog ? 'Stop logs' : 'Watch logs';
}
You need to use latest/newest
GoogleApiClient Api
Basically what you need to do is:
private GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
Then
@Override
public void onConnected(Bundle connectionHint) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
}
}
for the most accurate and reliable location. See my post here:
https://stackoverflow.com/a/33599228/2644905
Do not use LocationListener which is not accurate and has delayed response. To be honest this is easier to implement. Also read documentation: https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApiClient
You can get the same error in Asp.net MVC5 if you have a class name and a folder with a matching name Example : If you have class lands where when you want to see view/lands/index.cshtml file, if you also have a folder with name 'lands' you get the error as it first try the lands folder
In case you don't want (or have) a running container, you can call your script directly with the run
command.
Remove the iterative tty -i -t
arguments and use this:
$ docker run ubuntu:bionic /bin/bash /path/to/script.sh
This will (didn't test) also work for other scripts:
$ docker run ubuntu:bionic /usr/bin/python /path/to/script.py
From Qt5 onwards we can also use
Static Public Members of QThread
void msleep(unsigned long msecs)
void sleep(unsigned long secs)
void usleep(unsigned long usecs)
Can't you just change working directory within the python script using os.chdir(target)
? I agree, I can't see any way of doing it from the jar command itself.
If you don't want to permanently change directory, then store the current directory (using os.getcwd()
)in a variable and change back afterwards.
If you also need to process click events here some modifications:
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector = new GestureDetector(new GestureListener());
public boolean onTouch(final View v, final MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
result = onSwipeRight();
} else {
result = onSwipeLeft();
}
}
} else {
if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
result = onSwipeBottom();
} else {
result = onSwipeTop();
}
}
}
} catch (Exception exception) {
exception.printStackTrace();
}
return result;
}
}
public boolean onSwipeRight() {
return false;
}
public boolean onSwipeLeft() {
return false;
}
public boolean onSwipeTop() {
return false;
}
public boolean onSwipeBottom() {
return false;
}
}
And sample usage:
background.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
toggleSomething();
}
});
background.setOnTouchListener(new OnSwipeTouchListener() {
public boolean onSwipeTop() {
Toast.makeText(MainActivity.this, "top", Toast.LENGTH_SHORT).show();
return true;
}
public boolean onSwipeRight() {
Toast.makeText(MainActivity.this, "right", Toast.LENGTH_SHORT).show();
return true;
}
public boolean onSwipeLeft() {
Toast.makeText(MainActivity.this, "left", Toast.LENGTH_SHORT).show();
return true;
}
public boolean onSwipeBottom() {
Toast.makeText(MainActivity.this, "bottom", Toast.LENGTH_SHORT).show();
return true;
}
});

The findstr
command sets the ErrorLevel
(or exit code) to one of the following values, given that there are no invalid or incompatible switches and no search string exceeds the applicable length limit:
0
when at least a single match is encountered in one line throughout all specified files;1
otherwise;A line is considered to contain a match when:
/V
option is given and the search expression occurs at least once;/V
option is given and the search expression does not occur;This means that the /V
option also changes the returned ErrorLevel
, but it does not just revert it!
For example, when you have got a file test.txt
with two lines, one of which contains the string text
but the other one does not, both findstr "text" "test.txt"
and findstr /V "text" "test.txt"
return an ErrorLevel
of 0
.
Basically you can say: if findstr
returns at least a line, ErrorLevel
is set to 0
, else to 1
.
Note that the /M
option does not affect the ErrorLevel
value, it just alters the output.
(Just for the sake of completeness: the find
command behaves exactly the same way with respect to the /V
option and ErrorLevel
; the /C
option does not affect ErrorLevel
.)
When buffer size gets full. There are several options you can try:
1) Increase the size of the DBMS_OUTPUT buffer to 1,000,000
2) Try filtering the data written to the buffer - possibly there is a loop that writes to DBMS_OUTPUT and you do not need this data.
3) Call ENABLE at various checkpoints within your code. Each call will clear the buffer.
DBMS_OUTPUT.ENABLE(NULL) will default to 20000 for backwards compatibility Oracle documentation on dbms_output
You can also create your custom output display.something like below snippets
create or replace procedure cust_output(input_string in varchar2 )
is
out_string_in long default in_string;
string_lenth number;
loop_count number default 0;
begin
str_len := length(out_string_in);
while loop_count < str_len
loop
dbms_output.put_line( substr( out_string_in, loop_count +1, 255 ) );
loop_count := loop_count +255;
end loop;
end;

I know this might be redundant but I use this script to batch convert files.
old_extension=$1
new_extension=$2
for i in *."$old_extension";
do ffmpeg -i "$i" "${i%.*}.$new_extension";
done
It takes 2 arguments to make it more flexible :
I create an alias for it but you can also use it manually like this:
sh batch_convert.sh mkv mp4
This would convert all the mkv
files into mp4
files.
As you can see it slightly more versatile. As long as ffmpeg
can convert it you can specify any two extensions.
you can use this code to hide the tool tip change its title and show the tooltip again, when the ajax request returns successfully.
$(element).tooltip('hide');
$(element).attr('title','this is new title');
$(element).tooltip('fixTitle');
setTimeout(function() { $(element).tooltip('show');}, 500);
In my application,above javascript function didnt work,because i had many procrosses inside one page.so following code worked for me hope it helps you guys.
function redirection()
{
<?php $send=$_SERVER['HTTP_REFERER'];?>
var redirect_to="<?php echo $send;?>";
window.location = redirect_to;
}
This snippet could help you with it in a few lines of jQuery 1.9+: http://jsfiddle.net/4MBUG/2/
$('input[type=button]').on('click', function() {
var cursorPos = $('#text').prop('selectionStart');
var v = $('#text').val();
var textBefore = v.substring(0, cursorPos);
var textAfter = v.substring(cursorPos, v.length);
$('#text').val(textBefore + $(this).val() + textAfter);
});
You can just specify the python version when running a program:
for python 2:
python filename.py
for python 3:
python3 filename.py
This works for me
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
max_usb_current=1
You should stop the task that you have scheduled on the timer: Your timer:
Timer t = new Timer();
TimerTask tt = new TimerTask() {
@Override
public void run() {
//do something
};
}
t.schedule(tt,1000,1000);
In order to stop:
tt.cancel();
t.cancel(); //In order to gracefully terminate the timer thread
Notice that just cancelling the timer will not terminate ongoing timertasks.
I'd recommend using the Buffer
class:
var someEncodedString = Buffer.from('someString', 'utf-8');
This avoids any unnecessary dependencies that other answers require, since Buffer
is included with node.js
, and is already defined in the global scope.
Spring MVC offers a standaloneSetup that supports testing relatively simple controllers, without the need of context.
Build a MockMvc by registering one or more @Controller's instances and configuring Spring MVC infrastructure programmatically. This allows full control over the instantiation and initialization of controllers, and their dependencies, similar to plain unit tests while also making it possible to test one controller at a time.
An example test for your controller can be something as simple as
public class DemoApplicationTests {
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = standaloneSetup(new HelloWorld()).build();
}
@Test
public void testSayHelloWorld() throws Exception {
this.mockMvc.perform(get("/")
.accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
.andExpect(status().isOk())
.andExpect(content().contentType("application/json"));
}
}
It can be done all on the client-side using the OnClientClick
[MSDN] event handler and window.open
[MDN]:
<asp:Button
runat="server"
OnClientClick="window.open('http://www.stackoverflow.com'); return false;">
Open a new window!
</asp:Button>
import pandas as pd
df = pd.read_excel ('C:/Users/yourlogin/new folder/file.xlsx')
print (df)
If you are using Spring 4.1 and Java 8 you can use java.util.Optional
which is supported in @RequestParam
, @PathVariable
, @RequestHeader
and @MatrixVariable
in Spring MVC -
@RequestMapping(value = {"/json/{type}", "/json" }, method = RequestMethod.GET)
public @ResponseBody TestBean typedTestBean(
@PathVariable Optional<String> type,
@RequestParam("track") String track) {
if (type.isPresent()) {
//type.get() will return type value
//corresponds to path "/json/{type}"
} else {
//corresponds to path "/json"
}
}
I came up with this simple and straight-forward (i hope so) code example which should explain itself!
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
/* function header definitions */
char* getString(); //<- with malloc (good practice)
char * getStringNoMalloc(); //<- without malloc (fails! don't do this!)
void getStringCallByRef(char* reference); //<- callbyref (good practice)
/* the main */
int main(int argc, char*argv[]) {
//######### calling with malloc
char * a = getString();
printf("MALLOC ### a = %s \n", a);
free(a);
//######### calling without malloc
char * b = getStringNoMalloc();
printf("NO MALLOC ### b = %s \n", b); //this doesnt work, question to yourself: WHY?
//HINT: the warning says that a local reference is returned. ??!
//NO free here!
//######### call-by-reference
char c[100];
getStringCallByRef(c);
printf("CALLBYREF ### c = %s \n", c);
return 0;
}
//WITH malloc
char* getString() {
char * string;
string = malloc(sizeof(char)*100);
strcat(string, "bla");
strcat(string, "/");
strcat(string, "blub");
printf("string : '%s'\n", string);
return string;
}
//WITHOUT malloc (watch how it does not work this time)
char* getStringNoMalloc() {
char string[100] = {};
strcat(string, "bla");
strcat(string, "/");
strcat(string, "blub");
//INSIDE this function "string" is OK
printf("string : '%s'\n", string);
return string; //but after returning.. it is NULL? :)
}
// ..and the call-by-reference way to do it (prefered)
void getStringCallByRef(char* reference) {
strcat(reference, "bla");
strcat(reference, "/");
strcat(reference, "blub");
//INSIDE this function "string" is OK
printf("string : '%s'\n", reference);
//OUTSIDE it is also OK because we hand over a reference defined in MAIN
// and not defined in this scope (local), which is destroyed after the function finished
}
When compiling it, you get the [intended] warning:
me@box:~$ gcc -o example.o example.c
example.c: In function ‘getStringNoMalloc’:
example.c:58:16: warning: function returns address of local variable [-Wreturn-local-addr]
return string; //but after returning.. it is NULL? :)
^~~~~~
...basically what we are discussing here!
running my example yields this output:
me@box:~$ ./example.o
string : 'bla/blub'
MALLOC ### a = bla/blub
string : 'bla/blub'
NO MALLOC ### b = (null)
string : 'bla/blub'
CALLBYREF ### c = bla/blub
Theory:
This has been answered very nicely by User @phoxis. Basically think about it this way: Everything inbetween { and } is local scope, thus by the C-Standard is "undefined" outside. By using malloc you take memory from the HEAP (programm scope) and not from the STACK (function scope) - thus its 'visible' from outside. The second correct way to do it is call-by-reference. Here you define the var inside the parent-scope, thus it is using the STACK (because the parent scope is the main()).
Summary:
3 Ways to do it, One of them false. C is kind of to clumsy to just have a function return a dynamically sized String. Either you have to malloc and then free it, or you have to call-by-reference. Or use C++ ;)
Sometimes Just try drop header(.h) file and reAdd it as source(.cpp) NOT rename. Test in resharp c++ && vs2019 ,Test Code is Here
String img_url= //url of the image
URL url=new URL(img_url);
Bitmap bmp;
bmp=BitmapFactory.decodeStream(url.openConnection().getInputStream());
ImageView iv=(ImageView)findviewById(R.id.imageview);
iv.setImageBitmap(bmp);
After data-binding, do this:
ddlColor.Items.Insert(0, new ListItem("Select","NA")); //updated code
Or follow Brian's second suggestion if you want to do it in markup.
You should probably add a RequiredFieldValidator control and set its InitialValue to "NA".
<asp:RequiredFieldValidator .. ControlToValidate="ddlColor" InitialValue="NA" />
@gbtimmon's answer is great, but way, way too complicated. I've simplified his code as much as I could.

You're looking for the /Y
switch.
There's also the function tags, a bit more flexible:
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:if test="${fn:length(list) > 0}">
And here's the tag documentation.
str.copy(cstr, str.length()+1); // since C++11
cstr[str.copy(cstr, str.length())] = '\0'; // before C++11
cstr[str.copy(cstr, sizeof(cstr)-1)] = '\0'; // before C++11 (safe)
It's a better practice to avoid C in C++, so std::string::copy should be the choice instead of strcpy.

Perfect answer for your question can be found on MYSQL site itself.refer their manual(without using PHP)

According to them use LONGBLOB datatype. with that you can only store images less than 1MB only by default,although it can be changed by editing server config file.i would also recommend using MySQL workBench for ease of database management
