Programs & Examples On #Launching

On Mac

After trying a bunch of stuff, and several times doing a fresh git clone for the flutter project .. all to no avail, finally the only thing that worked was to download the MacOS .zip file and do a fresh install that way

If this error appeared for you after including kotlin support, and none of the other solutions work, try changing the kotlin dependency of app module's build.gradle to:

implementation ("org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version") {
    exclude group: 'org.jetbrains', module: 'annotations'
}

This works for me on Android Studio 3.0 Beta 6. See this answer for further explanation.

This error occurred for me when upgrading an Xcode 8 project to run in Xcode 9, however the iOS Base SDK in the Build Settings is still at the previous version of iPhoneOS10.3.sdk and says SDK not found. However that application still builds and runs on a device but it fails to launch. Updating the iOS Base SDK to iOS 11.0 fixes this launch problem.

ngModel is coming from FormsModule. There are some cases when you can receive this kind of error:

1. You didn't import the FormsModule into the import array of modules where your component is declared - the component in which the ngModel is used.
2. You have import the FormsModule into one module which is inherited of another module. In this case you have two options:

• let the FormsModule be imported into the import array from both modules:module1 and module2. As the rule: Importing a module does not provide access to its imported modules. (Imports are not inherited)

  

• declare the FormsModule into the import and export arrays in module1 to be able to see it in model2 also

  

3. (In some version I faced this problem) You have imported the FormsModule correctly, but the problem is on the input HTML tag. You must add the name tag attribute for the input, and the object bound name in [(ngModel)] must be the same as the name into the name attribute

   

I had a semicolon at the end, and gave me this error.

There is a project setting if you hunt down:

{project}/node_modules/react-native/local-cli/runIOS/runIOS.js

Within there are some options under module.exports including:

options: [{ command: '--simulator [string]', description: 'Explicitly set simulator to use', default: 'iPhone 7', }

Mine was line 231, simply set that to a valid installed simulator and run react-native run-ios it will run to that simulator by default.

You might have forwarding enabled on adb. You can try this: Quit Android studio and launch terminal. Run these commands:

adb kill-server
adb forward --remove-all
adb start-server 

Now you can launch Android Studio and try again.

Clearing the device data worked for me...

Close your emulator

Go to AVD Manager

Under "Actions" select "Wipe Data" (for the device your intend to use)

Then run your app again!

Hope this helps...

This issue may be because in the recent past you have used IP address binding in your application configuration.

Steps to Solve the issue:

• Run below command in administrator access command terminal

netsh http show iplisten

If you see some thing like below then this solution may not help you.

IP addresses present in the IP listen to list:

0.0.0.0

If you see something different than 0.0.0.0 then try below steps to fix this.

• Run following shell command in order with elevated command terminal

netsh http delete iplisten ipaddress=11.22.33.44

netsh http add iplisten ipaddress=0.0.0.0

iisreset

• (Here 11.22.33.44 is the actual IP that needs to be removed)

And now your issexpress is set to listen to any ping coming to localhost binding.

The simplest command as it can be for k8s pod manifest to run container forever:

apiVersion: v1
kind: Pod
metadata:
  name: ubuntu
spec:
  containers:
  - name: ubuntu
    image: ubuntu:latest
    # Just sleep forever
    command: [ "sleep" ]
    args: [ "infinity" ]

No issues with the latest kartoza/qgis-desktop

I ran

docker pull kartoza/qgis-desktop

followed by

docker run -it --rm --name "qgis-desktop-2-4" -v ${HOME}:/home/${USER} -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY kartoza/qgis-desktop:latest

I did try multiple times without the conflict error - you do have to exit the app beforehand. Also, please note the parameters do differ slightly.

link your currentily folders to vscode.

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

I faced this problem in android studio 3.0. Just restarted device solved.

For me, this issue was proxy related. In Mac osx, even while above error is displayed, there is menu bar for Android Studio at top. Select preferences Android Studio -> Preferences and change proxy as below and issue was resolved. There could be similar options in Windows/Linux to access preferences page while error is being displayed.

I fond this YouTube video from Google where are some tips and tricks for it. The video also includes advantages and disadvantages of suggested changes.

Improving Android Studio Performance on Memory-Constrained Machines

Swift 5 & Xcode 11

So in xCode 11 the window solution is no longer valid inside of appDelegate. They moved this to the SceneDelgate. You can find this in the SceneDelgate.swift file.

You will notice it now has a var window: UIWindow? present.

In my situation I was using a TabBarController from a storyboard and wanted to set it as the rootViewController.

This is my code:

sceneDelegate.swift

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
        // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
        // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).

        self.window = self.window ?? UIWindow()//@JA- If this scene's self.window is nil then set a new UIWindow object to it.

        //@Grab the storyboard and ensure that the tab bar controller is reinstantiated with the details below.
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let tabBarController = storyboard.instantiateViewController(withIdentifier: "tabBarController") as! UITabBarController

        for child in tabBarController.viewControllers ?? [] {
            if let top = child as? StateControllerProtocol {
                print("State Controller Passed To:")
                print(child.title!)
                top.setState(state: stateController)
            }
        }

        self.window!.rootViewController = tabBarController //Set the rootViewController to our modified version with the StateController instances
        self.window!.makeKeyAndVisible()

        print("Finished scene setting code")
        guard let _ = (scene as? UIWindowScene) else { return }
    }

Make sure to add this to the correct scene method as I did here. Note that you will need to set the identifier name for the tabBarController or viewController you are using in the storyboard.

In my case I was doing this to set a stateController to keep track of shared variables amongst the tab views. If you wish to do this same thing add the following code...

StateController.swift

import Foundation

struct tdfvars{
    var rbe:Double = 1.4
    var t1half:Double = 1.5
    var alphaBetaLate:Double = 3.0
    var alphaBetaAcute:Double = 10.0
    var totalDose:Double = 6000.00
    var dosePerFraction:Double = 200.0
    var numOfFractions:Double = 30
    var totalTime:Double = 168
    var ldrDose:Double = 8500.0
}

//@JA - Protocol that view controllers should have that defines that it should have a function to setState
protocol StateControllerProtocol {
  func setState(state: StateController)
}

class StateController {
    var tdfvariables:tdfvars = tdfvars()
}

Note: Just use your own variables or whatever you are trying to keep track of instead, I just listed mine as an example in tdfvariables struct.

In each view of the TabController add the following member variable.

    class SettingsViewController: UIViewController {
    var stateController: StateController?
.... }

Then in those same files add the following:

extension SettingsViewController: StateControllerProtocol {
  func setState(state: StateController) {
    self.stateController = state
  }
}

What this does is allows you to avoid the singleton approach to passing variables between the views. This allows easily for the dependency injection model which is much better long run then the singleton approach.

You need to read (and post) the output of

sc query intelhaxm

as stated on http://developer.android.com/tools/devices/emulator.html#accel-vm

You open a command prompt window by right click on the start menu, choose execute and write 'cmd'.

See also Android Emulator Doesn't Use HAXM .

If you cannot get the emulator to work you might want to try out an easier alternative: Genymotion - http://genymotion.com/

One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files

Other, alternative is to open the "Find in Files" window via the "Standard Toolbars" button as highlighted in the below screen-short:

The way I do it is:

in the location I run the spark-submit script do

$ cp /etc/spark/conf/log4j.properties .
$ nano log4j.properties

change INFO to what ever level of logging you want and then run your spark-submit

Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.

Xcode 11

1. Navigate to settings of your target and select General.
2. Look for "Frameworks, Libraries, and Embedded Content"
3. Keep "Do Not Embed" and make sure that all your targets (if you have more than one) have only set it's own framework and not others targets.

I actually figured this out myself. I'll add my solution as another option.

extension UIViewController {
    func prefersStatusBarHidden() -> Bool {
        return true
    }
}

Please see http://java.dzone.com/articles/how-debug-remote-java-applicat to enable the remote debugging. If you are using tomcat to run your application, start tomcat with remote debug parameters or you can start tomcat with JPDA support by using following command.

Windows

<tomcat bin dir>/startup.bat jpda

*nix

<tomcat bin dir>/startup.sh jpda

this will enable remote debugging on port 8000

Got the same problem today. Fixed it by changing the jdk location in the project structure from \java\jdk1.7.0_05 to \java\jdk1.7.0_25 (which I didn´t know existed until now).

I´m using Android Studio 0.8.6.

I encountered this error after installing Intellij IDEA Ultimate 14.1 and opening an existing Android project I had created using Android Studio. It turns out I just had to add the Android SDK to my list of SDKs and fix the project/module SDK settings. This is how I did it:

Go to File -> Project Structure. Click on the Project tab under Project Settings. Under Project SDK click on New -> Android SDK.

Now select the existing directory for your Android SDK. In my case it was in this folder:

C:\Users\<windows username>\AppData\Local\Android\android-sdk

Click Ok. A menu pops up asking you to set the Java SDK + Build target. You can either change these or leave it as its defaults and hit Ok. You should now see "Android API XX Platform" in the Project SDK dropdown. Click apply on the bottom. Then go to the Modules tab under Project Settings and click on the folders in the modules listing.

For each folder go to the dependencies tab and change the Module SDK to the new Android SDK and click apply. Then click Ok to close the Project Structure dialog.

After doing the above, my project was fixed.

Check if you are building hidden version. That’s intended behavior for hidden app.

If you want to build regular version, you need to change Build Variant in Android Studio Build > Select Build Variant, change it to regular.

You need to stop the server before re-launching. Look for the red box icon or server view.

Enable protected mode for all zones You need to enable protected mode for all zones from Internet Options -> Security tab. To enable protected mode for all zones.

I had the same issue running Rider/VS, both were using IIS Express to run it. I was having the issue with Postman, Chrome, Firefox and front end application calling it.

Turns out that because my laptop was appropriated for me when i started working for this company the previous developer had clicked No when asked if he wanted to use the Developer Cert the first time he ran IIS Express.

This was fixed on Windows 10 by going to Add Remove Programs (from the new UI there is a link on the right to launch the classic application for Adding and Removing Programs) then Repair IIS 10.0 or 8 or whatever version you are running.

Then try running the application again (I did this in VS but assume that Rider would do the same) and when asked whether you would like to use the Developer Certificate you click YES.

Hours wasted on this, but all sorted after that!

From what I've found online, this is a bug introduced in JDK 1.7.0_45. I've read it will be fixed in the next release of Java, but it's not out yet. Supposedly, it was fixed in 1.7.0_60b01, but I can't find where to download it and 1.7.0_60b02 re-introduces the bug.

I managed to get around the problem by reverting back to JDK 1.7.0_25. Probably not the solution you wanted, but it's the only way I've been able to get it working. Don't forget add JDK 1.7.0_25 in Eclipse after installing the JDK.

Please DO NOT REPLY directly to this email but go to StackOverflow: Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined

This is cross-posted from a blog post I wrote, but here is the full rundown on status bars, navigation bars, and container view controllers on iOS 7:

1. There is no way to preserve the iOS 6 style status bar layout. The status bar will always overlap your application on iOS 7

2. Do not confuse status bar appearance with status bar layout. The appearance (light or default) does not affect how the status bar is laid out (frame/height/overlap). It is important to note as well that the system status bar no longer has any background color. When the API refers to UIStatusBarStyleLightContent, they mean white text on a clear background. UIStatusBarStyleDefault is black text on a clear background.

3. Status bar appearance is controlled along one of two mutually-exclusive basis paths: you can either set them programmatically in the traditional manner, or UIKit will update the appearance for you based on some new properties of UIViewController. The latter option is on by default. Check your app’s plist value for “ViewController-Based Status Bar Appearance” to see which one you’re using. If you set this value to YES, every top-level view controller in your app (other than a standard UIKit container view controller) needs to override preferredStatusBarStyle, returning either the default or the light style. If you edit the plist value to NO, then you can manage the status bar appearance using the familiar UIApplication methods.

4. UINavigationController will alter the height of its UINavigationBar to either 44 points or 64 points, depending on a rather strange and undocumented set of constraints. If the UINavigationController detects that the top of its view’s frame is visually contiguous with its UIWindow’s top, then it draws its navigation bar with a height of 64 points. If its view’s top is not contiguous with the UIWindow’s top (even if off by only one point), then it draws its navigation bar in the “traditional” way with a height of 44 points. This logic is performed by UINavigationController even if it is several children down inside the view controller hierarchy of your application. There is no way to prevent this behavior.

5. If you supply a custom navigation bar background image that is only 44 points (88 pixels) tall, and the UINavigationController’s view’s bounds matches the UIWindow’s bounds (as discussed in #4), the UINavigationController will draw your image in the frame (0,20,320,44), leaving 20 points of opaque black space above your custom image. This may confuse you into thinking you are a clever developer who bypassed rule #1, but you are mistaken. The navigation bar is still 64 points tall. Embedding a UINavigationController in a slide-to-reveal style view hierarchy makes this abundantly clear.

6. Beware of the confusingly-named edgesForExtendedLayout property of UIViewController. Adjusting edgesForExtendedLayout does nothing in most cases. The only way UIKit uses this property is if you add a view controller to a UINavigationController, then the UINavigationController uses edgesForExtendedLayout to determine whether or not its child view controller should be visible underneath the navigation bar / status bar area. Setting edgesForExtendedLayout on the UINavigationController itself does nothing to alter whether or not the UINavigationController has a 44 or 64 point high navigation bar area. See #4 for that logic. Similar layout logic applies to the bottom of your view when using a toolbar or UITabBarController.

7. If all you are trying to do is prevent your custom child view controller from underlapping the navigation bar when inside a UINavigationController, then set edgesForExtendedLayout to UIRectEdgeNone (or at least a mask that excludes UIRectEdgeTop). Set this value as early as possible in the life cycle of your view controller.

8. UINavigationController and UITabBarController will also try to pad the contentInsets of table views and collection views in its subview hierarchy. It does this in a manner similar to the status bar logic from #4. There is a programmatic way of preventing this, by setting automaticallyAdjustsScrollViewInsets to NO for your table views and collection views (it defaults to YES). This posed some serious problems for Whisper and Riposte, since we use contentInset adjustments to control the layout of table views in response to toolbar and keyboard movements.

9. To reiterate: there is no way to return to iOS 6 style status bar layout logic. In order to approximate this, you have to move all the view controllers of your app into a container view that is offset by 20 points from the top of the screen, leaving an intentionally black view behind the status bar to simulate the old appearance. This is the method we ended up using in Riposte and Whisper.

10. Apple is pushing very hard to ensure that you don’t try to do #9. They want us to redesign all our apps to underlap the status bar. There are many cogent arguments, however, for both user experience and technical reasons, why this is not always a good idea. You should do what is best for your users and not simply follow the whimsy of the platform.

Try putting your code inside a main function in testMain.py

import parallelTestModule

if __name__ ==  '__main__':
  extractor = parallelTestModule.ParallelExtractor()
  extractor.runInParallel(numProcesses=2, numThreads=4)

See the docs:

"For an explanation of why (on Windows) the if __name__ == '__main__' 
part is necessary, see Programming guidelines."

which say

"Make sure that the main module can be safely imported by a new Python interpreter without causing unintended side effects (such a starting a new process)."

... by using if __name__ == '__main__'

I tested "jenv" and other things like setting "JAVA_HOME" without success. Now i and endet up with following solution

function setJava {
    export JAVA_HOME="$(/usr/libexec/java_home -v $1)"
    launchctl setenv JAVA_HOME $JAVA_HOME
    sudo ln -nsf "$(dirname ${JAVA_HOME})/MacOS" /Library/Java/MacOS 
    java -version
}

(added to ~/.bashrc or ~/.bash.profile or ~/.zshrc)

And calling like that:

setJava 1.8

java_home will handle the wrong input. so you can't do something wrong. Maven and other stuff will pick up the right version now.

You can change vagrant default machine name by changing value of config.vm.define.

Here is the simple Vagrantfile which uses getopts and allows you to change the name dynamically:

# -*- mode: ruby -*-
require 'getoptlong'

opts = GetoptLong.new(
  [ '--vm-name',        GetoptLong::OPTIONAL_ARGUMENT ],
)
vm_name        = ENV['VM_NAME'] || 'default'

begin
  opts.each do |opt, arg|
    case opt
      when '--vm-name'
        vm_name = arg
    end
  end
  rescue
end

Vagrant.configure(2) do |config|
  config.vm.define vm_name
  config.vm.provider "virtualbox" do |vbox, override|
    override.vm.box = "ubuntu/wily64"
    # ...
  end
  # ...
end

So to use different name, you can run for example:

vagrant --vm-name=my_name up --no-provision

^{Note: The --vm-name parameter needs to be specified before up command.}

or:

VM_NAME=my_name vagrant up --no-provision

This is an issue with the 64 bit version of Kepler and windows7 in my case. I downloaded the 32 bit and it worked immediately.

Ubuntu 16.04 64bit. I got the problem for apparently no reasons. The night before I watched a movie on my VideoLan instance, that night I would like to watch another one with VideoLan. VLC just didn't want to run because of the error into the question. I google a bit and I found the solution it solved my problem: from now on, VLC is runnable just like before. The solution is this comand:

sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/

I am not able to explain what are its consequencies, but I know it creates some missing symbolic link.

Yes, you can detect by this method in appDelegate:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
      /* your Code*/
}

For local Notification:

- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification
{
         /* your Code*/
}

Check your runtime tag inside the web.config, and verify you have something like this declared:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
.....
</runtime>

To make sure it's a simulator issue, see if you can connect to the simulator with a brand new project without changing any code. Try the tab bar template.

If you think it's a simulator issue, press the iOS Simulator menu. Select "Reset Content and Settings...". Press "Reset."

I can't see your XIB and what @properties you have connected in Interface Builder, but it could also be that you're not loading your window, or that your window is not loading your view controller.

You can use this configuration:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120913-144807
-showsplash

openFile
-vmargs
-Xms512m
-Xmx1024m
-XX:+UseParallelGC
-XX:PermSize=256M
-XX:MaxPermSize=512M

Simply try removing the ".xib" from the nib name in "initWithNibName:". According to the documentation, the ".xib" is assumed and shouldn't be used.

My first answer!

This will set the safemode switch:

bcdedit /set {current} safeboot minimal 

with networking:

bcdedit /set {current} safeboot network

then reboot the machine with

shutdown /r

to put back in normal mode via dos:

bcdedit /deletevalue {current} safeboot

I had the exact same problem running docker but I found the solution in the log preceding the error you've mentioned.

selenium_1  | 2016-11-11 11:19:34,498 DEBG 'xvfb' stderr output:

I've followed the advice and problem has been sorted out.

I had this same issue, there was no issue regarding memory in my server machine, Finally i was able to fix it by following steps

1. In your application hosting server, go to its "Component Services"
2. 

3.Find "Microsoft Excel Application" in right side.

4.Open its properties by right click

5.Under Identity tab select the option interactive user and click Ok button.

Check once again. Hope it helps

NOTE: But now you may end up with another COM error "Retrieving the COM class factory for component...". In that case Just set the Identity to this User and enter the username and password of a user who has sufficient rights. In my case I entered a user of power user group.

I done it, below code is working for me....

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.hello_world, container, false);

        Button newPage = (Button)v.findViewById(R.id.click);
        newPage.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getActivity(), HomeActivity.class);
                startActivity(intent);
            }
        });
        return v;
    }

and Please make sure that your destination activity should be register in Manifest.xml file,

but in my case all tabs are not shown in HomeActivity, is any solution for that ?

Explicitly adding a npm version to file package.json ("npm": "1.1.x") and not checking in folder node_modules to Git worked for me.

It may be slower to deploy (since it downloads the packages each time), but I couldn't get the packages to compile when they were checked in. Heroku was looking for files that only existed on my local box.

Even I faced the same issue - when checked on dashboard I found following Error. As the data was coming through Flume and had interrupted in between due to which may be there was inconsistency in few files.

Caused by: org.apache.hadoop.hive.serde2.SerDeException: org.codehaus.jackson.JsonParseException: Unexpected end-of-input within/between OBJECT entries

Running on fewer files it worked. Format consistency was the reason in my case.

If you created your provisioning profile before configuring the app ID for push, try to regenerate the provisioning profile.

iOS Provisioning Portal -> Provisioning -> Your cert -> EDIT -> Make an edit -> Download new provisioning

Worked for me. Now i'm able to use push.

Yes you can do that by just creating a BroadcastReceiver that calls your Service when your Application boots. Here is a complete answer given by me.
Android - Start service on boot

If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Just declare your Service as declared normally.

Check whether you are scheduling a task to trigger an executable (.exe) or a batch (.bat) file. If you have scheduled any other file to open (for example a .txt or .docx file), the file not open.

With transforms being more ubiquitously supported these days, you can do this without knowing the width/height of the popup

.popup {
    position: fixed;
    top: 50%;
    left: 50%;
    -webkit-transform: translate(-50%, -50%);
    transform: translate(-50%, -50%);
}

Easy! JSFiddle here: http://jsfiddle.net/LgSZV/

You are trying to load a XIB named DetailViewController, but no such XIB exists or it's not member of your current target.

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

I had this problem, and since overriding the onKeyDown() method didn't accomplish anything because of the underlying android system didn't call this method, I solved this with overriding onBackPressed(), and I had a boolean value set there to false, because I pressed back, let me show you what I mean in code:

import android.util.Log;
public class HomeButtonActivity extends Activity {
    boolean homePressed = false;
    // override onCreate() here.

    @Override
    public void onBackPressed() {
        homePressed = false; // simply set homePressed to false
    }

    @Overide
    public void onResume() {
        super.onResume();
        homePressed = true; // default: other wise onBackPressed will set it to false
    }

    @Override
    public void onPause() {
        super.onPause();
        if(homePressed) { Log.i("homePressed", "yay"); }
    }

So the reason why this worked is because the only way to navigate outside this activity is by pressing back or home so if back was pressed then i know the cause wasn't home, but otherwise the cause was home, therefore i set the default boolean value for homePressed to be true. However this will only work with a single activity instance in your application because otherwise you have more possibilities to cause the onPause() method to be called.

Starting from iOS 13 Apple has changed [deviceToken description]output. Now it is like this {length=32,bytes=0x0b8823aec3460e1724e795cba45d22e8...af8c09f971d0dabc} which is incorrect for device token.

I suggest to use this code snippet to resolve a problem:

+ (NSString *)stringFromDeviceToken:(NSData *)deviceToken {
    NSUInteger length = deviceToken.length;
    if (length == 0) {
        return nil;
    }
    const unsigned char *buffer = deviceToken.bytes;
    NSMutableString *hexString  = [NSMutableString stringWithCapacity:(length * 2)];
    for (int i = 0; i < length; ++i) {
        [hexString appendFormat:@"%02x", buffer[i]];
    }
    return [hexString copy];
}

It will work for iOS13 and lower.

We can pass string value to main method as argument without using commandline argument concept in java through Netbean

 package MainClass;
 import java.util.Scanner;
 public class CmdLineArgDemo {

static{
 Scanner readData = new Scanner(System.in);   
 System.out.println("Enter any string :");
 String str = readData.nextLine();
 String [] str1 = str.split(" ");
 // System.out.println(str1.length);
 CmdLineArgDemo.main(str1);
}  

   public static void main(String [] args){
      for(int i = 0 ; i<args.length;i++) {
        System.out.print(args[i]+" ");
      }
    }
  }

Output

Enter any string :

If you're coming here wondering the opposite (as I was), this post may be for you.

I couldn't figure out why my notifications were clearing when I cleared the badge...I manually increment the badge and then want to clear it when the user enters the app. That's no reason to clear out the notification center, though; they may still want to see or act on those notifications.

Negative 1 does the trick, luckily:

[UIApplication sharedApplication].applicationIconBadgeNumber = -1;

Start with:

setup.exe /?

And you should see a dialog popup with some options displayed.

This is pretty easy using the JavaScript selenium-webdriver client:

First, make sure you have a WebDriver server running. For example, download ChromeDriver, then run chromedriver --port=9515.

Second, create the driver like this:

var driver = new webdriver.Builder()
   .withCapabilities(webdriver.Capabilities.chrome())
   .usingServer('http://localhost:9515')  // <- this
   .build();

Here's a complete example:

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder()
   .withCapabilities(webdriver.Capabilities.chrome())
   .usingServer('http://localhost:9515')
   .build();

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.getTitle().then(function(title) {
   console.log(title);
 });

driver.quit();

Mac OSX only

An easier way to get going (assuming you already have homebrew installed, which you should, if not, go do that first and let homebrew make your life better) is to just run the following command:

brew install chromedriver

That should put the chromedriver in your path and you should be all set.

As of iOS8 you can open the built-in Settings app with:

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
   [[UIApplication sharedApplication] openURL:url];
}

The actual URL string is @"app-settings:". I tried appending different sections to the string ("Bluetooth", "GENERAL", etc.) but seems only linking to the main Settings screen works. Post a reply if you find out otherwise.

So here is my solution (similar to John Vance's answer):

First go here and get a function to detect mobile browsers.

http://detectmobilebrowsers.com/

They have a lot of different ways to detect if you are on mobile, so find one that works with what you are using.

Your HTML page (pseudo code):

If Mobile Then
    <input id="selling-date" type="date" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />
else
    <input id="selling-date" type="text" class="date-picker" readonly="readonly" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />

JQuery:

$( ".date-picker" ).each(function() {
    var min = $( this ).attr("min");
    var max = $( this ).attr("max");
    $( this ).datepicker({ 
        dateFormat: "yy-mm-dd",  
        minDate: min,  
        maxDate: max  
    });
});

This way you can still use native date selectors in mobile while still setting the min and max dates either way.

The field for non mobile should be read only because if a mobile browser like chrome for ios "requests desktop version" then they can get around the mobile check and you still want to prevent the keyboard from showing up.

However if the field is read only it could look to a user like they cant change the field. You could fix this by changing the CSS to make it look like it isn't read only (ie change border-color to black) but unless you are changing the CSS for all input tags you will find it hard to keep the look consistent across browsers.

To get arround that I just add a calendar image button to the date picker. Just change your JQuery code a bit:

$( ".date-picker" ).each(function() {
    var min = $( this ).attr("min");
    var max = $( this ).attr("max");
    $( this ).datepicker({ 
        dateFormat: "yy-mm-dd",  
        minDate: min,  
        maxDate: max,
        showOn: "both",
        buttonImage: "images/calendar.gif",
        buttonImageOnly: true,
        buttonText: "Select date"
    });
});

Note: you will have to find a suitable image.

<context:property-placeholder ... /> is the XML equivalent to the PropertyPlaceholderConfigurer. So, prefer that. The <util:properties/> simply factories a java.util.Properties instance that you can inject.

In Spring 3.1 (not 3.0...) you can do something like this:

@Configuration
@PropertySource("/foo/bar/services.properties")
public class ServiceConfiguration { 

    @Autowired Environment environment; 

    @Bean public javax.sql.DataSource dataSource( ){ 
        String user = this.environment.getProperty("ds.user");
        ...
    } 
}

In Spring 3.0, you can "access" properties defined using the PropertyPlaceHolderConfigurer mechanism using the SpEl annotations:

@Value("${ds.user}") private String user;

If you want to remove the XML all together, simply register the PropertyPlaceholderConfigurer manually using Java configuration. I prefer the 3.1 approach. But, if youre using the Spring 3.0 approach (since 3.1's not GA yet...), you can now define the above XML like this:

@Configuration 
public class MySpring3Configuration {     
        @Bean 
        public static PropertyPlaceholderConfigurer configurer() { 
             PropertyPlaceholderConfigurer ppc = ...
             ppc.setLocations(...);
             return ppc; 
        } 

        @Bean 
        public class DataSource dataSource(
                @Value("${ds.user}") String user, 
                @Value("${ds.pw}") String pw, 
                ...) { 
            DataSource ds = ...
            ds.setUser(user);
            ds.setPassword(pw);                        
            ...
            return ds;
        }
}

Note that the PPC is defined using a static bean definition method. This is required to make sure the bean is registered early, because the PPC is a BeanFactoryPostProcessor - it can influence the registration of the beans themselves in the context, so it necessarily has to be registered before everything else.

Have you tried setting the delegate, i.e.

self.rootController.delegate = self;

within applicationDidFinishLaunchingWithOptions? That worked for me, although I'm not sure why.

The problem in my case was that I needed to add environment variables for http_proxy and https_proxy.

E.g.,

http_proxy=http://your_proxy:your_port
https_proxy=https://your_proxy:your_port

To set these environment variables in Windows, see the answers to this question.

VAR1=value1 VAR2=value2 myScript args ...

There is an easy way without the need to use an external tool - it runs fine with Windows 7, 8, 8.1 and 10 and is backwards-compatible too (Windows XP doesn't have any UAC, thus elevation is not needed - in that case the script just proceeds).

Check out this code (I was inspired by the code by NIronwolf posted in the thread Batch File - "Access Denied" On Windows 7?), but I've improved it - in my version there isn't any directory created and removed to check for administrator privileges):

 ECHO %batchName% Arguments: P1=%1 P2=%2 P3=%3 P4=%4 P5=%5 P6=%6 P7=%7 P8=%8 P9=%9
 cmd /k

The script takes advantage of the fact that NET FILE requires administrator privilege and returns errorlevel 1 if you don't have it. The elevation is achieved by creating a script which re-launches the batch file to obtain privileges. This causes Windows to present the UAC dialog and asks you for the administrator account and password.

I have tested it with Windows 7, 8, 8.1, 10 and with Windows XP - it works fine for all. The advantage is, after the start point you can place anything that requires system administrator privileges, for example, if you intend to re-install and re-run a Windows service for debugging purposes (assumed that mypackage.msi is a service installer package):

msiexec /passive /x mypackage.msi
msiexec /passive /i mypackage.msi
net start myservice

Without this privilege elevating script, UAC would ask you three times for your administrator user and password - now you're asked only once at the beginning, and only if required.

If your script just needs to show an error message and exit if there aren't any administrator privileges instead of auto-elevating, this is even simpler: You can achieve this by adding the following at the beginning of your script:

@ECHO OFF & CLS & ECHO.
NET FILE 1>NUL 2>NUL & IF ERRORLEVEL 1 (ECHO You must right-click and select &
  ECHO "RUN AS ADMINISTRATOR"  to run this batch. Exiting... & ECHO. &
  PAUSE & EXIT /D)
REM ... proceed here with admin rights ...

This way, the user has to right-click and select "Run as administrator". The script will proceed after the REM statement if it detects administrator rights, otherwise exit with an error. If you don't require the PAUSE, just remove it. Important: NET FILE [...] EXIT /D) must be on the same line. It is displayed here in multiple lines for better readability!

On some machines, I've encountered issues, which are solved in the new version above already. One was due to different double quote handling, and the other issue was due to the fact that UAC was disabled (set to lowest level) on a Windows 7 machine, hence the script calls itself again and again.

I have fixed this now by stripping the quotes in the path and re-adding them later, and I've added an extra parameter which is added when the script re-launches with elevated rights.

The double quotes are removed by the following (details are here):

setlocal DisableDelayedExpansion
set "batchPath=%~0"
setlocal EnableDelayedExpansion

You can then access the path by using !batchPath!. It doesn't contain any double quotes, so it is safe to say "!batchPath!" later in the script.

The line

if '%1'=='ELEV' (shift & goto gotPrivileges)

checks if the script has already been called by the VBScript script to elevate rights, hence avoiding endless recursions. It removes the parameter using shift.

Update:

• To avoid having to register the .vbs extension in Windows 10, I have replaced the line
  "%temp%\OEgetPrivileges.vbs"
  by
  "%SystemRoot%\System32\WScript.exe" "%temp%\OEgetPrivileges.vbs"
  in the script above; also added cd /d %~dp0 as suggested by Stephen (separate answer) and by Tomáš Zato (comment) to set script directory as default.

• Now the script honors command line parameters being passed to it. Thanks to jxmallet, TanisDLJ and Peter Mortensen for observations and inspirations.

• According to Artjom B.'s hint, I analyzed it and have replaced SHIFT by SHIFT /1, which preserves the file name for the %0 parameter

• Added del "%temp%\OEgetPrivileges_%batchName%.vbs" to the :gotPrivileges section to clean up (as mlt suggested). Added %batchName% to avoid impact if you run different batches in parallel. Note that you need to use for to be able to take advantage of the advanced string functions, such as %%~nk, which extracts just the filename.

• Optimized script structure, improvements (added variable vbsGetPrivileges which is now referenced everywhere allowing to change the path or name of the file easily, only delete .vbs file if batch needed to be elevated)

• In some cases, a different calling syntax was required for elevation. If the script does not work, check the following parameters:
  set cmdInvoke=0
set winSysFolder=System32
  Either change the 1st parameter to set cmdInvoke=1 and check if that already fixes the issue. It will add cmd.exe to the script performing the elevation.
  Or try to change the 2nd parameter to winSysFolder=Sysnative, this might help (but is in most cases not required) on 64 bit systems. (ADBailey has reported this). "Sysnative" is only required for launching 64-bit applications from a 32-bit script host (e.g. a Visual Studio build process, or script invocation from another 32-bit application).

• To make it more clear how the parameters are interpreted, I am displaying it now like P1=value1 P2=value2 ... P9=value9. This is especially useful if you need to enclose parameters like paths in double quotes, e.g. "C:\Program Files".

• If you want to debug the VBS script, you can add the //X parameter to WScript.exe as first parameter, as suggested here (it is described for CScript.exe, but works for WScript.exe too).

I had the same problem. I made it work with:

"C:\Program Files (x86)\Android\android-sdk\tools\emulator-arm.exe"  @foo

foo is the name of your virtual device.

The most beginner-friendly solution is:

Drag a Timer from the Toolbox, give it a Name, set your desired Interval, and set "Enabled" to True. Then double-click the Timer and Visual Studio (or whatever you are using) will write the following code for you:

private void wait_Tick(object sender, EventArgs e)
{
    refreshText(); // Add the method you want to call here.
}

No need to worry about pasting it into the wrong code block or something like that.

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();
    (callback || function() {})();
});

New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

Okay, first a few terms slightly oversimplified.

In git, a tag (like many other things) is what's called a treeish. It's a way of referring to a point in in the history of the project. Treeishes can be a tag, a commit, a date specifier, an ordinal specifier or many other things.

Now a branch is just like a tag but is movable. When you are "on" a branch and make a commit, the branch is moved to the new commit you made indicating it's current position.

Your HEAD is pointer to a branch which is considered "current". Usually when you clone a repository, HEAD will point to master which in turn will point to a commit. When you then do something like git checkout experimental, you switch the HEAD to point to the experimental branch which might point to a different commit.

Now the explanation.

When you do a git checkout v2.0, you are switching to a commit that is not pointed to by a branch. The HEAD is now "detached" and not pointing to a branch. If you decide to make a commit now (as you may), there's no branch pointer to update to track this commit. Switching back to another commit will make you lose this new commit you've made. That's what the message is telling you.

Usually, what you can do is to say git checkout -b v2.0-fixes v2.0. This will create a new branch pointer at the commit pointed to by the treeish v2.0 (a tag in this case) and then shift your HEAD to point to that. Now, if you make commits, it will be possible to track them (using the v2.0-fixes branch) and you can work like you usually would. There's nothing "wrong" with what you've done especially if you just want to take a look at the v2.0 code. If however, you want to make any alterations there which you want to track, you'll need a branch.

You should spend some time understanding the whole DAG model of git. It's surprisingly simple and makes all the commands quite clear.

What Jichao said always works for me.

Generally when I see this error if I am using Eclipse I will close and reopen the program. I will then uninstall the Application from the target phone. This sometimes fixes the issue but not always.

Next I will open up the command terminal and head into the android-sdk then run:

./adb install <AppName>.apk

This does the same thing that running through Eclipse does but it will give you an error message.

(9 times out of 10 it simply says 'INSTALL_ALREADY_EXISTS' and I go and uninstall the application off the target phone again then run adb and I am working fine.)

I also needed colors, tags and remote references without any duplicates:

for ref in $(git for-each-ref --sort=-committerdate --format="%(refname)" refs/heads/ refs/remotes ); do git log -n1 $ref --pretty=format:"%Cgreen%cr%Creset %C(yellow)%d%Creset %C(bold blue)<%an>%Creset%n" | cat ; done | awk '! a[$0]++'

Because quoting can be hard, here is the alias for Bash:

alias glist='for ref in $(git for-each-ref --sort=-committerdate --format="%(refname)" refs/heads/ refs/remotes ); do git log -n1 $ref --pretty=format:"%Cgreen%cr%Creset %C(yellow)%d%Creset %C(bold blue)<%an>%Creset%n" | cat ; done | awk '"'! a["'$0'"]++'"

I faced same problem and tried above solutions but none of them worked for me. Then I tried following steps and the problem was solved:

• Go to the project properties.
• Go to Java Build Path option.
• Then add *.jar file as external jar.
• Then go to the order and export option and select the libraries and jars of the project.
• save the current changes and clean the project and run the project again.

When shell=True the shell is the child process, and the commands are its children. So any SIGTERM or SIGKILL will kill the shell but not its child processes, and I don't remember a good way to do it. The best way I can think of is to use shell=False, otherwise when you kill the parent shell process, it will leave a defunct shell process.

you may have some errors in your fields like

public class Search_costumer extends Activity {

// you may have some errors like this 
int x =3/0;
// I have error in initializing this variable too 
 MySimpleOnGestureListener mySimpleOnGestureListener =new MySimpleOnGestureListener();

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
}
}

so my advice is to perform all initialization in onCreate method not directly in your fields

solve like that

public class Search_costumer extends Activity {

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

// you may have some errors like this 
int x =3/0;
// I have error in initializing this variable too 
 MySimpleOnGestureListener mySimpleOnGestureListener =new MySimpleOnGestureListener();
}
}

Most of these answers are old. The latest Safari 14.0.2 (in 2021), has the option to Disable Cross-Origin Restrictions, however, it doesn't work if the paths have ../../ kind of path names; even though Safari correctly resolves to a local file path, it still doesn't permit loading the file, even though it exists. This is a recent bug in Safari 14 that didn't happen in 13.

This solution will allow you to load a local script using jQuery.getScript(). This is a global setting but you can also set the crossDomain option on a per-request basis.

$.ajaxPrefilter( "json script", function( options ) {
  options.crossDomain = true;
});

You can just use

explorer "https://google.com"

Which will launch your default browser and navigate to that site.

And on Mac I've using

open "https://google.com"

my case seems to be invalid JRE version.

1.7+ required while I launched with 1.6

plus: I filtered some plugin jars which might be required. so changed to select all

IF YOUR PROBLEM IS NOT SOLVED YET:

Visual studio's error is :

"The process cannot access the file 'bin\Debug**app.exe**' because it is being used by another process."

So ,go to task manager of windows(Ctrl+Shift+Esc),find your application name and force it to close by Endprocces.

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

Well you can try to open the built-in application Android Maps by using the Intent.setClassName method.

Intent i = new Intent(Intent.ACTION_VIEW,Uri.parse("geo:37.827500,-122.481670"));
i.setClassName("com.google.android.apps.maps",
    "com.google.android.maps.MapsActivity");
startActivity(i);

The standard way to pass a list of values as URL parameters is to repeat them:

http://our.api.com/Product?id=101404&id=7267261

Most server code will interpret this as a list of values, although many have single value simplifications so you may have to go looking.

Delimited values are also okay.

If you are needing to send JSON to the server, I don't like seeing it in in the URL (which is a different format). In particular, URLs have a size limitation (in practice if not in theory).

The way I have seen some do a complicated query RESTfully is in two steps:

1. POST your query requirements, receiving back an ID (essentially creating a search criteria resource)
2. GET the search, referencing the above ID
3. optionally DELETE the query requirements if needed, but note that they requirements are available for reuse.

I've been downloaded the "SDK ADT Bundle for Windows" adt-bundle-windows-x86.zip to "Documents and settings\myusername\My Documents\Downloads" and tried to unzip to a folder c:\Android

When all seems to be decompressed I saw some files where missing in the destination folder including the eclipse.ini.

I solved this by renaming adt-bundle-windows-x86.zip to a short name adt.zip, moving it to c:\ and repeating the decompression.

All is due to bad treatment of long file-names in windows

If anybody is looking for a swift version:

1) Create a custom class for your data

class customData: NSObject, NSCoding {
let name : String
let url : String
let desc : String

init(tuple : (String,String,String)){
    self.name = tuple.0
    self.url = tuple.1
    self.desc = tuple.2
}
func getName() -> String {
    return name
}
func getURL() -> String{
    return url
}
func getDescription() -> String {
    return desc
}
func getTuple() -> (String,String,String) {
    return (self.name,self.url,self.desc)
}

required init(coder aDecoder: NSCoder) {
    self.name = aDecoder.decodeObjectForKey("name") as! String
    self.url = aDecoder.decodeObjectForKey("url") as! String
    self.desc = aDecoder.decodeObjectForKey("desc") as! String
}

func encodeWithCoder(aCoder: NSCoder) {
    aCoder.encodeObject(self.name, forKey: "name")
    aCoder.encodeObject(self.url, forKey: "url")
    aCoder.encodeObject(self.desc, forKey: "desc")
} 
}

2) To save data use following function:

func saveData()
    {
        let data  = NSKeyedArchiver.archivedDataWithRootObject(custom)
        let defaults = NSUserDefaults.standardUserDefaults()
        defaults.setObject(data, forKey:"customArray" )
    }

3) To retrieve:

if let data = NSUserDefaults.standardUserDefaults().objectForKey("customArray") as? NSData
        {
             custom = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! [customData]
        }

Note: Here I am saving and retrieving an array of the custom class objects.

Just specify Intent.FLAG_ACTIVITY_NO_ANIMATION flag when starting

If javacpl does not open and gives you Could not find the main class:, it could be that Java is confused because of changes in deployment.properties (can be found in C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment on Win7). Delete that file and everything's fine.

This bug seems to be 6 years old, cf. An app should be able to ignore properties that have become obsolete over time, shouldn't it?

Use setDataAndType on the Intent

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(newVideoPath), "video/mp4");
startActivity(intent);

Use "video/mp4" as MIME or use "video/*" if you don't know the type.

This is regarding the question asked by Starter.

The problem with your code is that you are not passing the number properly.

The code should be:

private OnClickListener next = new OnClickListener() {

     public void onClick(View v) {
        EditText num=(EditText)findViewById(R.id.EditText01); 
        String number = "tel:" + num.getText().toString().trim();
        Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(number)); 
        startActivity(callIntent);
    }
};

Do not forget to add the permission in manifest file.

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

or

<uses-permission android:name="android.permission.CALL_PRIVILEGED"></uses-permission>

for emergency number in case DIAL is used.

The easiest way to do it is using Storyboard and a Segue.

Just create a Segue from the FirstViewController (not the Navigation Controller) of your TabBarController to a LoginViewController with the login UI and name it "showLogin".

Create a method that returns a BOOL to validate if the user logged in and/or his/her session is valid... preferably on the AppDelegate. Call it isSessionValid.

On your FirstViewController.m override the method viewDidAppear as follows:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    if([self isSessionValid]==NO){
        [self performSegueWithIdentifier:@"showLogin" sender:self];
    }
}

Then if the user logged in successfully, just dismiss or pop-out the LoginViewController to show your tabs.

Works 100%!

Hope it helps!

It might be that you have an expired development profile on your phone.

My development provisioning profile expired several days ago and I had to renew it. I installed the new profile on my phone and came up with the same error message when I tried to run my app. When I looked at the profile settings on my phone I noticed the expired profile and removed it. That cleared the error for me.

A lot of people have given some very technical answers for this and similar questions, but I think it's simpler than that. Sometimes if you're not paying attention a selector that you don't intend to use can be attached to something in the interface. You might be getting this error because the selector's there but you haven't written any code for it.

The easiest way to double-check that this is not the case is to control-click the item so you can see all of the selectors that are associated with it. If there's anything in there that you don't want to be, get rid of it! Hope this helps...

While there are several excellent answers, ranging from usual suspects to newer solutions, I would like to provide one more to the fray that addresses what you should do when you are working on a solution with multiple projects.

Before I arrived at this solution, I kept looking at bindingInformation in the applicationhost.config of the solution, tirelessly looking for any hint of why things were simply not working.

Turns out, the simple thing that I overlooked was that different projects have individual settings too.

So, besides Project > {Project-Name} Properties... > Web > Start Action on my Backend Project, I also had to Go to Website > Start Options... > Start Action on my Frontend Project. Once there, I selected Don't open a page. Wait for a request from an external application and have been happy ever since!

This error can also be caused by having zero methods tagged with the OperationContract attribute. This was my problem when building a new service and testing it a long the way.

Your shell process has a copy of the parent's environment and no access to the parent process's environment whatsoever. When your shell process terminates any changes you've made to its environment are lost. Sourcing a script file is the most commonly used method for configuring a shell environment, you may just want to bite the bullet and maintain one for each of the two flavors of shell.

You can't do it using environment variables. It's done via "non standard" options. Run: java -X for details. The options you're looking for are -Xmx and -Xms (this is "initial" heap size, so probably what you're looking for.)

I don't know if something like that already exists. It would be easy to write your own with time, datetime and/or calendar modules, see http://docs.python.org/library/time.html

The only concern for a python solution is that your job needs to be always running and possibly be automatically "resurrected" after a reboot, something for which you do need to rely on system dependent solutions.

WinSCP works fine on Linux under Wine. I installed Wine and WinSCP and had no problems.

Here's a snippet of helpful code:

using System.Diagnostics;

// Prepare the process to run
ProcessStartInfo start = new ProcessStartInfo();
// Enter in the command line arguments, everything you would enter after the executable name itself
start.Arguments = arguments; 
// Enter the executable to run, including the complete path
start.FileName = ExeName;
// Do you want to show a console window?
start.WindowStyle = ProcessWindowStyle.Hidden;
start.CreateNoWindow = true;
int exitCode;


// Run the external process & wait for it to finish
using (Process proc = Process.Start(start))
{
     proc.WaitForExit();

     // Retrieve the app's exit code
     exitCode = proc.ExitCode;
}

There is much more you can do with these objects, you should read the documentation: ProcessStartInfo, Process.

This worked for me:

start /d IEXPLORE.EXE www.google.com
start /d IEXPLORE.EXE www.yahoo.com

But for some reason opened them up in Firefox instead?!?

I tried this but it merely opened up sites in two different windows:

start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.google.com
start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.yahoo.com

You can use the System.Diagnostics.Process.Start method to start a process. You can even pass a URL as a string and it'll kick off the default browser.

I read somewhere else that you can try - catch java.lang.OutOfMemoryError and on the catch block, you can free all resources that you know might use a lot of memory, close connections and so forth, then do a System.gc() then re-try whatever you were going to do.

Another way is this although, i don't know whether this would work, but I am currently testing whether it will work on my application.

The Idea is to do Garbage collection by calling System.gc() which is known to increase free memory. You can keep checking this after a memory gobbling code executes.

//Mimimum acceptable free memory you think your app needs
long minRunningMemory = (1024*1024);

Runtime runtime = Runtime.getRuntime();

if(runtime.freeMemory()<minRunningMemory)
 System.gc();

var x= {}
var y= {x:'hi'}
console.log(Object.keys(x).length===0)
console.log(Object.keys(y).length===0)

true
false

For primitives just use (string)$var or print this variable straight away. PHP is dynamically typed language and variable will be casted to string on the fly.

If you want to convert objects to strings you will need to define __toString() method that returns string. This method is forbidden to throw exceptions.

for num in range(1,101):
    prime = True
    for i in range(2,num/2):
        if (num%i==0):
            prime = False
    if prime:
       print num

Your JSON is not correct. Instead of

JSONObject cred = new JSONObject();
JSONObject auth=new JSONObject();
JSONObject parent=new JSONObject();
cred.put("username","adm");
cred.put("password", "pwd");
auth.put("tenantName", "adm");
auth.put("passwordCredentials", cred.toString()); // <-- toString()
parent.put("auth", auth.toString());              // <-- toString()

OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());

write

JSONObject cred = new JSONObject();
JSONObject auth=new JSONObject();
JSONObject parent=new JSONObject();
cred.put("username","adm");
cred.put("password", "pwd");
auth.put("tenantName", "adm");
auth.put("passwordCredentials", cred);
parent.put("auth", auth);

OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());

So, the JSONObject.toString() should be called only once for the outer object.

Another thing (most probably not your problem, but I'd like to mention it):

To be sure not to run into encoding problems, you should specify the encoding, if it is not UTF-8:

con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
con.setRequestProperty("Accept", "application/json");

// ...

OutputStream os = con.getOutputStream();
os.write(parent.toString().getBytes("UTF-8"));
os.close();

Python 3 does not allow deletion while iterating (using for loop above) dictionary. There are various alternatives to do; one simple way is the to change following line

for i in x.keys():

With

for i in list(x)

I had a similar issue uploading to an S3 bucket protected with KWS encryption. I have a minimal policy that allows the addition of objects under a specific s3 key.

I needed to add the following KMS permissions to my policy to allow the role to put objects in the bucket. (Might be slightly more than are strictly required)

• Resolved it by enabling Application Server feature. Restarted iis after that.

A modification to GUS's example:

$(document).ready(function() {
    var tmpImg = new Image() ;
    tmpImg.onload = function() {
        // Run onload code.
    } ;

tmpImg.src = $('#img').attr('src');
})

Set the source before and after the onload.

if (jQuery){
   //jquery loaded
}

What about putting it into cron.hourly, waiting until the next run of hourly cron jobs, then removing it? That would run it once within an hour, and in the cron environment. You can also run ./your_script, but that won't have the same environment as under cron.

let fullNameArr : [String] = fullName.components(separatedBy: ".")

var firstName : String = fullNameArr[0]
var lastName : String = fullNameArr[1]

After you get from Eclipse the ugly CheckoutConflictException, the Eclipse-Merge Tool button is disabled.

Git need alle your files added to the Index for enable Merging.

So, to merge your Changes and commit them you need to add your files first to the index "Add to Index" and "Commit" them without "Push". Then you should see one pending pull and one pending push request in Eclipse. You see that in one up arrow and one down arrow.

If all conflict Files are in the commit, you can "pull" again. Then you will see something like:

\< < < < < < < HEAD Server Version \======= Local Version > > > > > > > branch 'master' of ....git

Then you either change it by the Merge-Tool, which is now enable or just do the merge by hand direct in the file. In the last step, you have to add the modified files again to the index and "Commit and Push" them.

Checking done!

You can simply add a FontAwesome icon to your select dropdown as text. You only need a few things in CSS only, the FontAwesome CSS and the unicode. For example :

select {_x000D_
  font-family: 'FontAwesome', 'Second Font name'_x000D_
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>_x000D_

  <option>Hi, &#xf043;</option>_x000D_
  <option>Hi, &#xf044;</option>_x000D_
  <option>Hi, &#xf045;</option>_x000D_
  <option>Hi, &#xf046;</option>_x000D_
</select>

I just want to point out that most of the answers here don't work, I am new to NodeJS and IDK if throughout time the "module.exports.yourClass" method changed, or if people just entered the wrong answer.

// MyClass

module.exports.Ninja = class Ninja{
    test(){
        console.log('TESTING 1... 2... 3...');
    };
}

//Using MyClass in seprate File


const ninjaFw = require('./NinjaFw');

let ninja = new ninjaFw.Ninja();
ninja.test();

• This is the method I am currently using. I like this syntax, becuase module.exports sits on the same line as the class declaration and that cleans the code up a little imo. The other way you can do it is like this:

//  Ninja Framework File


class Ninja{
    test(){
        console.log('TESTING 1... 2... 3...');
    };
}


module.exports.Ninja = Ninja;

• Two different syntax but, in the end, the same result. Just a matter of syntax anesthetics.

• SQL is a query language to operate on sets.

  It is more or less standardized, and used by almost all relational database management systems: SQL Server, Oracle, MySQL, PostgreSQL, DB2, Informix, etc.

• PL/SQL is a proprietary procedural language used by Oracle

• PL/pgSQL is a procedural language used by PostgreSQL

• TSQL is a proprietary procedural language used by Microsoft in SQL Server.

Procedural languages are designed to extend SQL's abilities while being able to integrate well with SQL. Several features such as local variables and string/data processing are added. These features make the language Turing-complete.

They are also used to write stored procedures: pieces of code residing on the server to manage complex business rules that are hard or impossible to manage with pure set-based operations.

I was also facing the same problem with gradle. Now I have solved by installing the highlighted in red. To navigate on this page Open Android studio > Tool > Android > SDK Manager > Appearance & Behavior > System Settings > Android SDK > SDK Tools (from tab options) > Show Package details(check box on the right bottom corner). After installing these just refresh the gradle everything will be resolved.

Building on the previous answers, please note an important point, you also need to manipulate your table column to ensure it does not contain the time fragment of the datetime datatype.

Below is a small sample script demonstrating the above:

select getdate()
--2012-05-01 12:06:51.413
select cast(getdate() as date)
--2012-05-01

--we're using sysobjects for the example
create table test (id int)
select * from sysobjects where cast(crdate as date) = cast(getdate() as date)
--resultset contains only objects created today
drop table test

I hope this helps.

EDIT:
Following @dwurf comment (thanks) about the effect the above example may have on performance, I would like to suggest the following instead. We create a date range between today at midnight (start of day) and the last millisecond of the day (SQL server count up to .997, that's why I'm reducing 3 milliseconds). In this manner we avoid manipulating the left side and avoid the performance impact.

select getdate()
--2012-05-01 12:06:51.413
select dateadd(millisecond, -3, cast(cast(getdate()+1 as date) as datetime))
--2012-05-01 23:59:59.997
select cast(getdate() as date)
--2012-05-01

create table test (id int)
select * from sysobjects where crdate between cast(getdate() as date) and dateadd(millisecond, -3, cast(cast(getdate()+1 as date) as datetime))
--resultset contains only objects created today
drop table test

To extend the given answer with few useful tricks:

var markers = //some array;
var bounds = new google.maps.LatLngBounds();
for(i=0;i<markers.length;i++) {
   bounds.extend(markers[i].getPosition());
}

//center the map to a specific spot (city)
map.setCenter(center); 

//center the map to the geometric center of all markers
map.setCenter(bounds.getCenter());

map.fitBounds(bounds);

//remove one zoom level to ensure no marker is on the edge.
map.setZoom(map.getZoom()-1); 

// set a minimum zoom 
// if you got only 1 marker or all markers are on the same address map will be zoomed too much.
if(map.getZoom()> 15){
  map.setZoom(15);
}

//Alternatively this code can be used to set the zoom for just 1 marker and to skip redrawing.
//Note that this will not cover the case if you have 2 markers on the same address.
if(count(markers) == 1){
    map.setMaxZoom(15);
    map.fitBounds(bounds);
    map.setMaxZoom(Null)
}

UPDATE:
Further research in the topic show that fitBounds() is a asynchronic and it is best to make Zoom manipulation with a listener defined before calling Fit Bounds.
Thanks @Tim, @xr280xr, more examples on the topic : SO:setzoom-after-fitbounds

google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
  this.setZoom(map.getZoom()-1);

  if (this.getZoom() > 15) {
    this.setZoom(15);
  }
});
map.fitBounds(bounds);

You can use is_uploaded_file():

if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
    echo 'No upload';
}

From the docs:

Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.

This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to the user, or even to other users on the same system.

EDIT: I'm using this in my FileUpload class, in case it helps:

public function fileUploaded()
{
    if(empty($_FILES)) {
        return false;       
    } 
    $this->file = $_FILES[$this->formField];
    if(!file_exists($this->file['tmp_name']) || !is_uploaded_file($this->file['tmp_name'])){
        $this->errors['FileNotExists'] = true;
        return false;
    }

I've created several color themes, and a script to extract a new one from someone's color preferences. I'm currently using one I still have yet to post on the site, but I should eventually get to it.

Create a wrapper class. Something like this:

public class Date:IEquatable<Date>,IEquatable<DateTime>
    {
        public Date(DateTime date)
        {
            value = date.Date;
        }

        public bool Equals(Date other)
        {
            return other != null && value.Equals(other.value);
        }

        public bool Equals(DateTime other)
        {
            return value.Equals(other);
        }

        public override string ToString()
        {
            return value.ToString();
        }
        public static implicit operator DateTime(Date date)
        {
            return date.value;
        }
        public static explicit operator Date(DateTime dateTime)
        {
            return new Date(dateTime);
        }

        private DateTime value;
    }

And expose whatever of value you want.

Java 8 has a new String.chars() method which returns a stream of characters in the String. You can use stream operations to filter out the duplicate characters like so:

String out = in.chars()
            .mapToObj(c -> Character.valueOf((char) c)) // bit messy as chars() returns an IntStream, not a CharStream (which doesn't exist)
            .distinct()
            .map(Object::toString)
            .collect(Collectors.joining(""));

This is of particular annoyance in IE. Basically you have to send 'no-cache' HTTP headers back with your response from the server.

I am using the Spring framework's RestTemplate in my client programme and, at the server-side, I defined a GET request with a Json body. My primary purpose is the same as yours: when the request has numerous parameters, putting them in the body seems tidier than putting them in the prolonged URI string. Yes?

But, sadly, it's not working! The server-side threw the following exception:

org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing...

But I am pretty sure the message body is correctly provided by my client code, so what's wrong?

I traced into the RestTemplate.exchange() method and found the following:

// SimpleClientHttpRequestFactory.class
public class SimpleClientHttpRequestFactory implements ClientHttpRequestFactory, AsyncClientHttpRequestFactory {
    ...
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        ...
        if (!"POST".equals(httpMethod) && !"PUT".equals(httpMethod) && !"PATCH".equals(httpMethod) && !"DELETE".equals(httpMethod)) {
            connection.setDoOutput(false);
        } else {
            connection.setDoOutput(true);
        }
        ...
    }
}

// SimpleBufferingClientHttpRequest.class
final class SimpleBufferingClientHttpRequest extends AbstractBufferingClientHttpRequest {
    ...
    protected ClientHttpResponse executeInternal(HttpHeaders headers, byte[] bufferedOutput) throws IOException {
        ...
        if (this.connection.getDoOutput() && this.outputStreaming) {
            this.connection.setFixedLengthStreamingMode(bufferedOutput.length);
        }

        this.connection.connect();
        if (this.connection.getDoOutput()) {
            FileCopyUtils.copy(bufferedOutput, this.connection.getOutputStream());
        } else {
            this.connection.getResponseCode();
        }
        ...
    }
}

Please notice that in the executeInternal() method, the input argument 'bufferedOutput' contains the message body provided by my code. I saw it through the debugger.

However, due to the prepareConnection(), the getDoOutput() in executeInternal() always returns false which, in turn, makes the bufferedOutput completely ignored! It's not copied into the output stream.

Consequently, my server programme received no message body and threw that exception.

This is an example about the RestTemplate of the Spring framework. The point is that, even if the message body is no longer forbidden by the HTTP spec, some client or server libraries or frameworks might still comply with the old spec and reject the message body from the GET request.

.outside {
    width: 200px;
    height: 200px;
    background-color: #EEE; /*to make it visible*/
}

Needs to be

.outside {
    position: relative;
    width: 200px;
    height: 200px;
    background-color: #EEE; /*to make it visible*/
}

Absolute positioning looks for the nearest relatively positioned parent within the DOM, if one isn't defined it will use the body.

If @Cybernate's solution doesn't work, try breaking the trigger off in to it's own function so you can reference it.

clickHandler = function(event){
  if (click++ == 49)
    canvas.removeEventListener('click',clickHandler);
}
canvas.addEventListener('click',clickHandler);

While you are switching, switch to PDO instead of mysqli, It helps you write database agnositc code and have better features for prepared statements.

http://www.php.net/pdo

Bindparam for PDO: http://se.php.net/manual/en/pdostatement.bindparam.php

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = :value1 && field2 = :value2");
$sth->bindParam(':value1', 'foo');
$sth->bindParam(':value2', 'bar');
$sth->execute();

or:

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = ? && field2 = ?");
$sth->bindParam(1, 'foo');
$sth->bindParam(2, 'bar');
$sth->execute();

or execute with the parameters as an array:

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = :value1 && field2 = :value2");
$sth->execute(array(':value1' => 'foo' , ':value2' => 'bar'));

It will be easier for you if you would like your application to be able to run on different databases in the future.

I also think you should invest some time in using some of the classes from Zend Framwework whilst working with PDO. Check out their Zend_Db and more specifically [Zend_Db_Factory][2]. You do not have to use all of the framework or convert your application to the MVC pattern, but using the framework and reading up on it is time well spent.

the answer is yes you can

try it like that

UPDATE TABLE_A a 
    JOIN TABLE_B b ON a.join_col = b.join_col AND a.column_a = b.column_b 
    JOIN TABLE_C c ON [condition]
SET a.column_c = a.column_c + 1

EDIT:

For general Update join :

   UPDATE TABLEA a 
   JOIN TABLEB b ON a.join_colA = b.join_colB  
   SET a.columnToUpdate = [something]

Just a small observation: you keep mentioning conn usr\pass, and this is a typo, right? Cos it should be conn usr/pass. Or is it different on a Unix based OS?

Furthermore, just to be sure: if you use tnsnames, your login string will look different from when you use the login method you started this topic out with.

tnsnames.ora should be in $ORACLE_HOME$\network\admin. That is the Oracle home on the machine from which you are trying to connect, so in your case your PC. If you have multiple oracle_homes and wish to use only one tnsnames.ora, you can set environment variable tns_admin (e.g. set TNS_ADMIN=c:\oracle\tns), and place tnsnames.ora in that directory.

Your original method of logging on (usr/[email protected]:port/servicename) should always work. So far I think you have all the info, except for the port number, which I am sure your DBA will be able to give you. If this method still doesn't work, either the server's IP address is not available from your client, or it is a firewall issue (blocking a certain port), or something else not (directly) related to Oracle or SQL*Plus.

hth! Regards, Remco

you can do:

adb pull /storage/emulated/0/Android/data//

This will do it:

wc -c filename

If you want only the count without the filename being repeated in the output:

wc -c < filename

Edit:

Use -m to count character instead of bytes (as shown in Sébastien's answer).

I've submitted a pull request (available in Ansible 2.2+) that will make this kinds of situations easier by adding jmespath query support on Ansible. In your case it would work like:

- debug: msg="{{ addresses | json_query(\"private_man[?type=='fixed'].addr\") }}"

would return:

ok: [localhost] => {
    "msg": [
        "172.16.1.100"
    ]
}

python3 -m pip install mysql-connector
pip install mysqlclient

These commands helpful to settingup the mysql db in django without errors

You can write integer in xml file also..
have you seen [this] http://developer.android.com/guide/topics/resources/more-resources.html#Integer ? use as .

 context.getResources().getInteger(R.integer.height_pop);

Restarting my PC made it worked.

Both getSingleResult() and getOneOrNullResult() will throw an exception if there is more than one result. To fix this problem you could add setMaxResults(1) to your query builder.

 $firstSubscriber = $entity->createQueryBuilder()->select('sub')
        ->from("\Application\Entity\Subscriber", 'sub')
        ->where('sub.subscribe=:isSubscribe')
        ->setParameter('isSubscribe', 1)  
        ->setMaxResults(1)
        ->getQuery()
        ->getOneOrNullResult();

Maybe the problem is the configuration of the mail server. To avoid this type of problems or you do not have to worry about the mail server problem, I recommend you use PHPMailer.

It is a plugin that has everything necessary to send mail, and the only thing you have to take into account is to have the SMTP port (Port: 25 and 465), enabled.

require_once 'PHPMailer/PHPMailer.php';
require_once '/servicios/PHPMailer/SMTP.php';
require_once '/servicios/PHPMailer/Exception.php';

$mail = new \PHPMailer\PHPMailer\PHPMailer(true);
try {
    //Server settings
    $mail->SMTPDebug = 0;
    $mail->isSMTP();
    $mail->Host = 'smtp.gmail.com';
    $mail->SMTPAuth = true;
    $mail->Username = '[email protected]';
    $mail->Password = 'contrasenia';
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;

    // Recipients
    $mail->setFrom('[email protected]', 'my name');
    $mail->addAddress('[email protected]');

    // Attachments
    $mail->addAttachment('optional file');         // Add files, is optional

    // Content
    $mail->isHTML(true);// Set email format to HTML
    $mail->Subject = utf8_decode("subject");
    $mail->Body    = utf8_decode("mail content");
    $mail->AltBody = '';
    $mail->send();
}
catch (Exception $e) {
    $error = $mail->ErrorInfo;
}

Above methods will remove your output file data whenever you run above nohup command.

To Append output in user defined file you can use >> in nohup command.

nohup your_command >> filename.out &

This command will append all output in your file without removing old data.

A perl-solution:

perl -nE 'say $1 if /id=(\d+)/' filename

 void gen_random(char *s, size_t len) {
     for (size_t i = 0; i < len; ++i) {
         int randomChar = rand()%(26+26+10);
         if (randomChar < 26)
             s[i] = 'a' + randomChar;
         else if (randomChar < 26+26)
             s[i] = 'A' + randomChar - 26;
         else
             s[i] = '0' + randomChar - 26 - 26;
     }
     s[len] = 0;
 }

Here's the working version of the code in question (requires at least version Matplotlib 1.1.0 from 2011-11-14):

import numpy as np
import matplotlib.pyplot as plt

plt.axis([0, 10, 0, 1])

for i in range(10):
    y = np.random.random()
    plt.scatter(i, y)
    plt.pause(0.05)

plt.show()

Note some of the changes:

1. Call plt.pause(0.05) to both draw the new data and it runs the GUI's event loop (allowing for mouse interaction).

Here's an alternative to Arun's first solution, with a simpler Perl-like regular expression:

as.numeric(gsub("[^\\d]+", "", years, perl=TRUE))

all your code is okay only the things left is just go to the link https://myaccount.google.com/security

and keep scroll down and you will found Allow less secure apps: ON and keep ON, you will find no error.

Ok so there are many answers here and I dont think they answer your question which I think is similar to mine.

You need to do an operation like contacting a database or third part api that will take time and is asyncronus. You do not want to load the entire document into memory due to being to large or some other reason so you need to read line by line to process.

I have read into the fs documents and it can pause on reading but using .on('data') call will make it continous which most of these answer use and cause the problem.

UPDATE: I know more info about Streams than I ever wanted

The best way to do this is to create a writable stream. This will pipe the csv data into your writable stream which you can manage asyncronus calls. The pipe will manage the buffer all the way back to the reader so you will not wind up with heavy memory usage

Simple Version

const parser = require('csv-parser');
const stripBom = require('strip-bom-stream');
const stream = require('stream')

const mySimpleWritable = new stream.Writable({
  objectMode: true, // Because input is object from csv-parser
  write(chunk, encoding, done) { // Required
    // chunk is object with data from a line in the csv
    console.log('chunk', chunk)
    done();
  },
  final(done) { // Optional
    // last place to clean up when done
    done();
  }
});
fs.createReadStream(fileNameFull).pipe(stripBom()).pipe(parser()).pipe(mySimpleWritable)

Class Version

const parser = require('csv-parser');
const stripBom = require('strip-bom-stream');
const stream = require('stream')
// Create writable class
class MyWritable extends stream.Writable {
  // Used to set object mode because we get an object piped in from csv-parser
  constructor(another_variable, options) {
    // Calls the stream.Writable() constructor.
    super({ ...options, objectMode: true });
    // additional information if you want
    this.another_variable = another_variable
  }
  // The write method
  // Called over and over, for each line in the csv
  async _write(chunk, encoding, done) {
    // The chunk will be a line of your csv as an object
    console.log('Chunk Data', this.another_variable, chunk)

    // demonstrate await call
    // This will pause the process until it is finished
    await new Promise(resolve => setTimeout(resolve, 2000));

    // Very important to add.  Keeps the pipe buffers correct.  Will load the next line of data
    done();
  };
  // Gets called when all lines have been read
  async _final(done) {
    // Can do more calls here with left over information in the class
    console.log('clean up')
    // lets pipe know its done and the .on('final') will be called
    done()
  }
}

// Instantiate the new writable class
myWritable = new MyWritable(somevariable)
// Pipe the read stream to csv-parser, then to your write class
// stripBom is due to Excel saving csv files with UTF8 - BOM format
fs.createReadStream(fileNameFull).pipe(stripBom()).pipe(parser()).pipe(myWritable)

// optional
.on('finish', () => {
  // will be called after the wriables internal _final
  console.log('Called very last')
})

OLD METHOD:

PROBLEM WITH readable

const csv = require('csv-parser');
const fs = require('fs');

const processFileByLine = async(fileNameFull) => {

  let reading = false

  const rr = fs.createReadStream(fileNameFull)
  .pipe(csv())

  // Magic happens here
  rr.on('readable', async function(){
    // Called once when data starts flowing
    console.log('starting readable')

    // Found this might be called a second time for some reason
    // This will stop that event from happening
    if (reading) {
      console.log('ignoring reading')
      return
    }
    reading = true
    
    while (null !== (data = rr.read())) {
      // data variable will be an object with information from the line it read
      // PROCESS DATA HERE
      console.log('new line of data', data)
    }

    // All lines have been read and file is done.
    // End event will be called about now so that code will run before below code

    console.log('Finished readable')
  })


  rr.on("end", function () {
    // File has finished being read
    console.log('closing file')
  });

  rr.on("error", err => {
    // Some basic error handling for fs error events
    console.log('error', err);
  });
}

You will notice a reading flag. I have noticed that for some reason right near the end of the file the .on('readable') gets called a second time on small and large files. I am unsure why but this blocks that from a second process reading the same line items.

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

An example of how to do this using a lambda expression would be:

issublist = lambda x, y: 0 in [_ in x for _ in y]

Depends on what you mean by better. This works if your goal is removal of redundancy.

s='foo'
string='%s bar baz %s bar baz %s bar baz' % (3*(s,))

My website is a subdomain which is developed on angular 8 which is also using localstorage and cookies. website showed after setting the below line, along with other solutions mentioned above.

webSettings.setDomStorageEnabled(true);

With re-use of @doesn't matters' solution, but with a one statement by avoiding the ${:1} substition and need of an intermediary variable.

echo $(printf "%s," "${LIST[@]}" | cut -d "," -f 1-${#LIST[@]} )

printf has 'The format string is reused as often as necessary to satisfy the arguments.' in its man pages, so that the concatenations of the strings is documented. Then the trick is to use the LIST length to chop the last sperator, since cut will retain only the lenght of LIST as fields count.

These days listen for oninput. It feels like onchange without the need to lose focus on the element. It is HTML5.

It’s supported by everyone (even mobile), except IE8 and below. For IE add onpropertychange. I use it like this:

const source = document.getElementById('source');_x000D_
const result = document.getElementById('result');_x000D_
_x000D_
const inputHandler = function(e) {_x000D_
  result.innerHTML = e.target.value;_x000D_
}_x000D_
_x000D_
source.addEventListener('input', inputHandler);_x000D_
source.addEventListener('propertychange', inputHandler); // for IE8_x000D_
// Firefox/Edge18-/IE9+ don’t fire on <select><option>_x000D_
// source.addEventListener('change', inputHandler); 

<input id="source">_x000D_
<div id="result"></div>

Here is my global module I use -

var Cookie = {   

   Create: function (name, value, days) {

       var expires = "";

        if (days) {
           var date = new Date();
           date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
           expires = "; expires=" + date.toGMTString();
       }

       document.cookie = name + "=" + value + expires + "; path=/";
   },

   Read: function (name) {

        var nameEQ = name + "=";
        var ca = document.cookie.split(";");

        for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charAt(0) == " ") c = c.substring(1, c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
        }

        return null;
    },

    Erase: function (name) {

        Cookie.create(name, "", -1);
    }

};

UPDATE

This answer was submitted when Angular 2 was still in alpha and many of the features were unavailable / undocumented. While the below will still work, this method is now entirely outdated. I strongly recommend the accepted answer over the below.

Original Answer

Yes in fact it is, however you will want to make sure that it is scoped correctly. For this I've used a property to ensure that this means what I want it to.

@Component({
  ...
  template: '<child [myCallback]="theBoundCallback"></child>',
  directives: [ChildComponent]
})
export class ParentComponent{
  public theBoundCallback: Function;

  public ngOnInit(){
    this.theBoundCallback = this.theCallback.bind(this);
  }

  public theCallback(){
    ...
  }
}

@Component({...})
export class ChildComponent{
  //This will be bound to the ParentComponent.theCallback
  @Input()
  public myCallback: Function; 
  ...
}

Just pass var2 as an extra argument to one of the apply functions.

mylist <- list(a=1,b=2,c=3)
myfxn <- function(var1,var2){
  var1*var2
}
var2 <- 2

sapply(mylist,myfxn,var2=var2)

This passes the same var2 to every call of myfxn. If instead you want each call of myfxn to get the 1st/2nd/3rd/etc. element of both mylist and var2, then you're in mapply's domain.

#For Unable to 'apt update' my Ubuntu 19.04

The repositories for older releases that are not supported (like 11.04, 11.10 and 13.04) get moved to an archive server. There are repositories available at http://old-releases.ubuntu.com.

first break up this file

cp /etc/apt/sources.list /etc/apt/sources.list.bak sudo sed -i -re 's/([a-z]{2}.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

then

sudo apt-get update && sudo apt-get dist-upgrade

This is another version which work in case you have some tasks to cleanup. Code will leave clean up process in their method.

package main

import (
    "fmt"
    "os"
    "os/signal"
    "syscall"

)



func main() {

    _,done1:=doSomething1()
    _,done2:=doSomething2()

    //do main thread


    println("wait for finish")
    <-done1
    <-done2
    fmt.Print("clean up done, can exit safely")

}

func doSomething1() (error, chan bool) {
    //do something
    done:=make(chan bool)
    c := make(chan os.Signal, 2)
    signal.Notify(c, os.Interrupt, syscall.SIGTERM)
    go func() {
        <-c
        //cleanup of something1
        done<-true
    }()
    return nil,done
}


func doSomething2() (error, chan bool) {
    //do something
    done:=make(chan bool)
    c := make(chan os.Signal, 2)
    signal.Notify(c, os.Interrupt, syscall.SIGTERM)
    go func() {
        <-c
        //cleanup of something2
        done<-true
    }()
    return nil,done
}

in case you need to clean main function you need to capture signal in main thread using go func() as well.

There's no such thing as an empty char. The closest you can get is '\0', the Unicode "null" character. Given that you can embed that within string literals or express it on its own very easily, why would you want a separate field for it? Equally, the "it's easy to confuse "" and " "" arguments don't apply for '\0'.

If you could give an example of where you'd want to use it and why you think it would be better, that might help...

While string interpolation will work, as your question specifies rails 4, you could be using Arel for this and keeping your app database agnostic.

def self.search(query, page=1)
  query = "%#{query}%"
  name_match = arel_table[:name].matches(query)
  postal_match = arel_table[:postal_code].matches(query)
  where(name_match.or(postal_match)).page(page).per_page(5)
end

I thought about a subtle change, which doesn't change the default bootstrap behavior. And I can use it only when I needed it:

.table-container {
  display: table;
}

.table-container .table-row {
  height: 100%;
  display: table-row;
}

.table-container .table-row .table-col {
  display: table-cell;
  float: none;
  vertical-align: top;
}

so I can have use it like this:

<div class="container table-container">
  <div class="row table-row">
    <div class="col-lg-4 table-col"> ... </div>
    <div class="col-lg-4 table-col"> ... </div>
    <div class="col-lg-4 table-col"> ... </div>
  </div>
</div>

I assume you have your JS file declared inside the <head> tag so it keeps it consistent, like standard, then in your JS make sure the canvas initialization is after the page is loaded:

window.onload = function () {
    var myCanvas = document.getElementById('canvas');
    var ctx = myCanvas.getContext('2d');
}

There is no need to use jQuery just to initialize a canvas, it's very evident most of the programmers all around the world use it unnecessarily and the accepted answer is a probe of that.

PATH vendor/composer/autoload_classmap.php

• Composer dump-autoload won’t download a thing.
• It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php).
• Ideal for when you have a new class inside your project.
• autoload_classmap.php also includes the providers in config/app.php

php artisan dump-autoload

• It will call Composer with the optimize flag
• It will 'recompile' loads of files creating the huge bootstrap/compiled.php

not sure why the previous answer was so complicated:

    cat Makefile | grep "^[A-z]" | awk '{print $$1}' | sed "s/://g" 

From http://www.coderanch.com/t/236675/java-programmer-SCJP/certification/xff

The hex literal 0xFF is an equal int(255). Java represents int as 32 bits. It look like this in binary:

00000000 00000000 00000000 11111111

When you do a bit wise AND with this value(255) on any number, it is going to mask(make ZEROs) all but the lowest 8 bits of the number (will be as-is).

... 01100100 00000101 & ...00000000 11111111 = 00000000 00000101

& is something like % but not really.

And why 0xff? this in ((power of 2) - 1). All ((power of 2) - 1) (e.g 7, 255...) will behave something like % operator.

Then
In binary, 0 is, all zeros, and 255 looks like this:

00000000 00000000 00000000 11111111

And -1 looks like this

11111111 11111111 11111111 11111111

When you do a bitwise AND of 0xFF and any value from 0 to 255, the result is the exact same as the value. And if any value higher than 255 still the result will be within 0-255.

However, if you do:

-1 & 0xFF

you get

00000000 00000000 00000000 11111111, which does NOT equal the original value of -1 (11111111 is 255 in decimal).

Few more bit manipulation: (Not related to the question)

X >> 1 = X/2
X << 1 = 2X

Check any particular bit is set(1) or not (0) then

 int thirdBitTobeChecked =   1 << 2   (...0000100)
 int onWhichThisHasTobeTested = 5     (.......101)

 int isBitSet = onWhichThisHasTobeTested  & thirdBitTobeChecked;
 if(isBitSet > 0) {
  //Third Bit is set to 1 
 } 

Set(1) a particular bit

 int thirdBitTobeSet =   1 << 2    (...0000100)
 int onWhichThisHasTobeSet = 2     (.......010)
 onWhichThisHasTobeSet |= thirdBitTobeSet;

ReSet(0) a particular bit

int thirdBitTobeReSet =   ~(1 << 2)  ; //(...1111011)
int onWhichThisHasTobeReSet = 6      ;//(.....000110)
onWhichThisHasTobeReSet &= thirdBitTobeReSet;

XOR

Just note that if you perform XOR operation twice, will results the same value.

byte toBeEncrypted = 0010 0110
byte salt          = 0100 1011

byte encryptedVal  =  toBeEncrypted ^ salt == 0110 1101
byte decryptedVal  =  encryptedVal  ^ salt == 0010 0110 == toBeEncrypted :)

One more logic with XOR is

if     A (XOR) B == C (salt)
then   C (XOR) B == A
       C (XOR) A == B

The above is useful to swap two variables without temp like below

a = a ^ b; b = a ^ b; a = a ^ b;

OR

a ^= b ^= a ^= b;

I had the same issue to remove old fragments. I ended up clearing the layout that contained the fragments.

LinearLayout layout = (LinearLayout) a.findViewById(R.id.layoutDeviceList);
layout.removeAllViewsInLayout();
FragmentTransaction ft = getFragmentManager().beginTransaction();
...

I do not know if this creates leaks, but it works for me.

Try this

public static long Hextonumber(String hexval)
    {
        hexval="0x"+hexval;
//      String decimal="0x00000bb9";
        Long number = Long.decode(hexval);
//.......       System.out.println("String [" + hexval + "] = " + number);
        return number;
        //3001
    }

You could use a regular expression replace:

str = str.replace(/ +(?= )/g,'');

Credit: The above regex was taken from Regex to replace multiple spaces with a single space

A file is almost a list of lines. You can trivially use it in a for loop.

myFile= open( "SomeFile.txt", "r" )
for x in myFile:
    print x
myFile.close()

Or, if you want an actual list of lines, simply create a list from the file.

myFile= open( "SomeFile.txt", "r" )
myLines = list( myFile )
myFile.close()
print len(myLines), myLines

You can't do someList[i] to put a new item at the end of a list. You must do someList.append(i).

Also, never start a simple variable name with an uppercase letter. List confuses folks who know Python.

Also, never use a built-in name as a variable. list is an existing data type, and using it as a variable confuses folks who know Python.

What is a raw type and why do I often hear that they shouldn't be used in new code?

A "raw type" is the use of a generic class without specifying a type argument(s) for its parameterized type(s), e.g. using List instead of List<String>. When generics were introduced into Java, several classes were updated to use generics. Using these class as a "raw type" (without specifying a type argument) allowed legacy code to still compile.

"Raw types" are used for backwards compatibility. Their use in new code is not recommended because using the generic class with a type argument allows for stronger typing, which in turn may improve code understandability and lead to catching potential problems earlier.

What is the alternative if we can't use raw types, and how is it better?

The preferred alternative is to use generic classes as intended - with a suitable type argument (e.g. List<String>). This allows the programmer to specify types more specifically, conveys more meaning to future maintainers about the intended use of a variable or data structure, and it allows compiler to enforce better type-safety. These advantages together may improve code quality and help prevent the introduction of some coding errors.

For example, for a method where the programmer wants to ensure a List variable called 'names' contains only Strings:

List<String> names = new ArrayList<String>();
names.add("John");          // OK
names.add(new Integer(1));  // compile error

From the session_destroy() page in the PHP manual:

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>

There's a facility to have a separate style sheet for print, using

 <link type="text/css" rel="stylesheet" media="print" href="print.css">

I don't know if it does what you want though.

The selected answer will only work if there are no gaps in the sequence. However if you are using an autogenerated id, there are likely to be gaps in the sequence due to inserts that were rolled back.

This method should work if you have gaps

declare @temp (value int, primaryKey int, tempid int identity)
insert value, primarykey from mytable order by  primarykey

select t1.value - t2.value from @temp  t1
join @temp  t2 
on t1.tempid = t2.tempid - 1

All you need to do is run

pip install /opt/mypackage

and pip will search /opt/mypackage for a setup.py, build a wheel, then install it.

The problem with using the -e flag for pip install as suggested in the comments and this answer is that this requires that the original source directory stay in place for as long as you want to use the module. It's great if you're a developer working on the source, but if you're just trying to install a package, it's the wrong choice.

Alternatively, you don't even need to download the repo from Github at all. pip supports installing directly from git repos using a variety of protocols including HTTP, HTTPS, and SSH, among others. See the docs I linked to for examples.

Create a constructor of FeedAdapter :

Context context; //global
public FeedAdapter(Context context)
{
   this.context = context;  
}

and in Activity

FeedAdapter obj = new FeedAdapter(this);

If you want to select a value based on true / false use

[selected]="opt.selected == true"

 <option *ngFor="let opt of question.options" [value]="opt.key" [selected]="opt.selected == true">{{opt.selected+opt.value}}</option>

Angular 2 - Setting selected value on dropdown list

To change all classes for an element:

document.getElementById("ElementID").className = "CssClass";

To add an additional class to an element:

document.getElementById("ElementID").className += " CssClass";

To check if a class is already applied to an element:

if ( document.getElementById("ElementID").className.match(/(?:^|\s)CssClass(?!\S)/) )

Here's the more concise and easy to read solution based on offset width difference:

function getScrollbarWidth(): number {

  // Creating invisible container
  const outer = document.createElement('div');
  outer.style.visibility = 'hidden';
  outer.style.overflow = 'scroll'; // forcing scrollbar to appear
  outer.style.msOverflowStyle = 'scrollbar'; // needed for WinJS apps
  document.body.appendChild(outer);

  // Creating inner element and placing it in the container
  const inner = document.createElement('div');
  outer.appendChild(inner);

  // Calculating difference between container's full width and the child width
  const scrollbarWidth = (outer.offsetWidth - inner.offsetWidth);

  // Removing temporary elements from the DOM
  outer.parentNode.removeChild(outer);

  return scrollbarWidth;

}

See the JSFiddle.

A couple short, sweet extension methods on IEnumerable and IEnumerable<T> do it for me:

public static IEnumerable Append(this IEnumerable first, params object[] second)
{
    return first.OfType<object>().Concat(second);
}
public static IEnumerable<T> Append<T>(this IEnumerable<T> first, params T[] second)
{
    return first.Concat(second);
}   
public static IEnumerable Prepend(this IEnumerable first, params object[] second)
{
    return second.Concat(first.OfType<object>());
}
public static IEnumerable<T> Prepend<T>(this IEnumerable<T> first, params T[] second)
{
    return second.Concat(first);
}

Elegant (well, except for the non-generic versions). Too bad these methods are not in the BCL.

So typically there are two ways to iterate through string in java which has already been answered by multiple people here in this thread, just adding my version of it First is using

String s = sc.next() // assuming scanner class is defined above
for(int i=0; i<s.length; i++){
     s.charAt(i)   // This being the first way and is a constant time operation will hardly add any overhead
  }

char[] str = new char[10];
str = s.toCharArray() // this is another way of doing so and it takes O(n) amount of time for copying contents from your string class to character array

If performance is at stake then I will recommend to use the first one in constant time, if it is not then going with the second one makes your work easier considering the immutability with string classes in java.

Using a text area field, you could use this: (Via Google)

<form name="select_all">

    <textarea name="text_area" rows="10" cols="80" 
    onClick="javascript:this.form.text_area.focus();this.form.text_area.select();">

    Text Goes Here 

    </textarea>
</form>

This is how I see most websites do it. They just style it with CSS so it doesn't look like a textarea.

You need to access the underlying buffer:

printf("%s\n", someString.c_str());

Or better use cout << someString << endl; (you need to #include <iostream> to use cout)

Additionally you might want to import the std namespace using using namespace std; or prefix both string and cout with std::.

PHP escapes forward slashes by default which is probably why this appears so commonly. I'm not sure why, but possibly because embedding the string "</script>" inside a <script> tag is considered unsafe.

This functionality can be disabled by passing in the JSON_UNESCAPED_SLASHES flag but most developers will not use this since the original result is already valid JSON.

Just select the code and

• on Windows do Ctrl + Alt + L

• on Linux do Ctrl + Windows Key + Alt + L

• on Mac do CMD + Option + L

Unfortunately most of add-ons and browser extensions are just showing the values to you but they don't let you to edit scope variables or run angular functions. If you wanna change the $scope variables in browser console (in all browsers) then you can use jquery. If you load jQuery before AngularJS, angular.element can be passed a jQuery selector. So you could inspect the scope of a controller with

angular.element('[ng-controller="name of your controller"]').scope()

Example: You need to change value of $scope variable and see the result in the browser then just type in the browser console:

angular.element('[ng-controller="mycontroller"]').scope().var1 = "New Value";
angular.element('[ng-controller="mycontroller"]').scope().$apply();

You can see the changes in your browser immediately. The reason we used $apply() is: any scope variable updated from outside angular context won't update it binding, You need to run digest cycle after updating values of scope using scope.$apply() .

For observing a $scope variable value, you just need to call that variable.

Example: You wanna see the value of $scope.var1 in the web console in Chrome or Firefox just type:

angular.element('[ng-controller="mycontroller"]').scope().var1;

The result will be shown in the console immediately.

since npm 5.2.0, there's a new command "npx" included with npm that makes this much simpler, if you run:

npx mocha <args>

Note: the optional args are forwarded to the command being executed (mocha in this case)

this will automatically pick the executable "mocha" command from your locally installed mocha (always add it as a dev dependency to ensure the correct one is always used by you and everyone else).

Be careful though that if you didn't install mocha, this command will automatically fetch and use latest version, which is great for some tools (like scaffolders for example), but might not be the most recommendable for certain dependencies where you might want to pin to a specific version.

You can read more on npx here

Now, if instead of invoking mocha directly, you want to define a custom npm script, an alias that might invoke other npm binaries...

you don't want your library tests to fail depending on the machine setup (mocha as global, global mocha version, etc), the way to use the local mocha that works cross-platform is:

node node_modules/.bin/mocha

npm puts aliases to all the binaries in your dependencies on that special folder. Finally, npm will add node_modules/.bin to the PATH automatically when running an npm script, so in your package.json you can do just:

"scripts": {
  "test": "mocha"
}

and invoke it with

npm test

If you are using the EditText inside TextInputLayout use app:boxBackgroundMode="none" as following:

<com.google.android.material.textfield.TextInputLayout
    app:boxBackgroundMode="none"
    ...
    >

        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</com.google.android.material.textfield.TextInputLayout>

I resolved this issue by Adding implements Serializable in the Model.

@Entity
@Table(name="Model_Rest")
@IdClass(Model_Rest.class)
public class Model_Rest implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    /**
     * 
     */
    //@GeneratedValue(strategy = GenerationType.AUTO)
    //@Column(columnDefinition="id")

    @Id
    private String login;
    @Id
    private String password;




    @Autowired
    public String getLogin() {
        return login;
    }

    @Autowired
    public void setLogin(String login) {
        this.login = login;
    }

    @Autowired
    public String getPassword() {
        return password;
    }

    @Autowired
    public void setPassword(String password) {
        this.password = password;
    }

    public Model_Rest() {
        // TODO Auto-generated constructor stub
    }

    public Model_Rest(String login, String password) {
        this.login = login;
        this.password = password;
    }

    @Override
    public String toString() {
        return "Model_Rest [login=" + login + ", password=" + password + "]";
    }
  }

This is yet another way:

$('selector')[0].tagName

The other offical way would be using git bundle

That will create a file that support git fetch and git pull in order to update your second repo.
Useful for incremental backup and restore.

But if you need to backup everything (because you do not have a second repo with some older content already in place), the backup is a bit more elaborate to do, as mentioned in my other answer, after Kent Fredric's comment:

$ git bundle create /tmp/foo master
$ git bundle create /tmp/foo-all --all
$ git bundle list-heads /tmp/foo
$ git bundle list-heads /tmp/foo-all

(It is an atomic operation, as opposed to making an archive from the .git folder, as commented by fantabolous)

Warning: I wouldn't recommend Pat Notz's solution, which is cloning the repo.
Backup many files is always more tricky than backing up or updating... just one.

If you look at the history of edits of the OP Yar answer, you would see that Yar used at first a clone --mirror, ... with the edit:

Using this with Dropbox is a total mess.
You will have sync errors, and you CANNOT ROLL A DIRECTORY BACK IN DROPBOX.
Use git bundle if you want to back up to your dropbox.

Yar's current solution uses git bundle.

I rest my case.

These two commands should do it:

:set autoindent
:set cindent

For bonus points put them in a file named .vimrc located in your home directory on linux

Controller code

myApp.controller('mainController', ['$scope', '$log', function($scope, $log) {
    $scope.person = {
        name:"sangeetha PH",
       address:"first Block"
    }
}]);

Directive Code

myApp.directive('searchResult',function(){
   return{
       restrict:'AECM',
       templateUrl:'directives/search.html',
       replace: true,
       scope:{
           personName:"@",
           personAddress:"@"
       }
   } 
});

USAGE

File :directives/search.html
content:

<h1>{{personName}} </h1>
<h2>{{personAddress}}</h2>

the File where we use directive

<search-result person-name="{{person.name}}" person-address="{{person.address}}"></search-result>

Its due to a conflict.

Clear all keys from ssh-agent

ssh-add -d ~/.ssh/id_rsa
ssh-add -d ~/.ssh/github

Add the github ssh key

ssh-add   ~/.ssh/github

It should work now.

try:

function removeClassName(elem, name){
    var remClass = elem.className;
    var re = new RegExp('(^| )' + name + '( |$)');
    remClass = remClass.replace(re, '$1');
    remClass = remClass.replace(/ $/, '');
    elem.className = remClass;
}

startActivity(new Intent(this, Katra_home.class));

try this one it will be work

Here is a nice summary table from cppreference.com:

Here, insertion refers to any method which adds one or more elements to the container and erasure refers to any method which removes one or more elements from the container.

You could also just run

go build

Then you can just type

./myprog

If you're currently on the branch you want to rename:

git branch -m new_name 

Or else:

git branch -m old_name new_name 

You can check with:

git branch -a

As you can see, only the local name changed Now, to change the name also in the remote you must do:

git push origin :old_name

This removes the branch, then upload it with the new name:

git push origin new_name

In my case, there were an error in the php.ini open_basedir variable.

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

If youtube-dl is a terminal program, you can use the subprocess module to access the data you want.

Appending data to an existing array is a natural thing to want to do for anyone with python experience. However, if you find yourself regularly appending to large arrays, you'll quickly discover that NumPy doesn't easily or efficiently do this the way a python list will. You'll find that every "append" action requires re-allocation of the array memory and short-term doubling of memory requirements. So, the more general solution to the problem is to try to allocate arrays to be as large as the final output of your algorithm. Then perform all your operations on sub-sets (slices) of that array. Array creation and destruction should ideally be minimized.

That said, It's often unavoidable and the functions that do this are:

for 2-D arrays:

• np.hstack
• np.vstack
• np.column_stack
• np.row_stack

for 3-D arrays (the above plus):

• np.dstack

for N-D arrays:

• np.concatenate

Having been in the development game for almost 20 years, this chestnut has continued to plague me across multiple projects.

As such, today whilst experiencing this same problem again, against another project, I decided to investigate further and I do believe this is related to Bin folder location... or more specifically, the output path of the bin folder.

For me, for a simple service based web application configured to run/debug through IIS, it was changing the output path from bin\debug to bin\ that resolved it

Project > Properties > Build > Output path

Seriously hopes this helps.

If you know the type of image and only want to generate a file, there's no need to get a BufferedImage instance. Just write the bytes to a file with the correct extension.

try (OutputStream out = new BufferedOutputStream(new FileOutputStream(path))) {
    out.write(bytes);
}

There are many possibilities to solve this task.

1. RUN the batch file with full path

The easiest solution is running the batch file with full path.

"F:\- Big Packets -\kitterengine\Common\Template.bat"

Once end of batch file Template.bat is reached, there is no return to previous script in case of the command line above is within a *.bat or *.cmd file.

The current directory for the batch file Template.bat is the current directory of the current process. In case of Template.bat requires that the directory of this batch file is the current directory, the batch file Template.bat should contain after @echo off as second line the following command line:

cd /D "%~dp0"

Run in a command prompt window cd /? for getting displayed the help of this command explaining parameter /D ... change to specified directory also on a different drive.

Run in a command prompt window call /? for getting displayed the help of this command used also in 2., 4. and 5. solution and explaining also %~dp0 ... drive and path of argument 0 which is the name of the batch file.

2. CALL the batch file with full path

Another solution is calling the batch file with full path.

call "F:\- Big Packets -\kitterengine\Common\Template.bat"

The difference to first solution is that after end of batch file Template.bat is reached the batch processing continues in batch script containing this command line.

For the current directory read above.

3. Change directory and RUN batch file with one command line

There are 3 operators for running multiple commands on one command line: &, && and ||.
For details see answer on Single line with multiple commands using Windows batch file

I suggest for this task the && operator.

cd /D "F:\- Big Packets -\kitterengine\Common" && Template.bat

As on first solution there is no return to current script if this is a *.bat or *.cmd file and changing the directory and continuation of batch processing on Template.bat is successful.

4. Change directory and CALL batch file with one command line

This command line changes the directory and on success calls the batch file.

cd /D "F:\- Big Packets -\kitterengine\Common" && call Template.bat

The difference to third solution is the return to current batch script on exiting processing of Template.bat.

5. Change directory and CALL batch file with keeping current environment with one command line

The four solutions above change the current directory and it is unknown what Template.bat does regarding

1. current directory
2. environment variables
3. command extensions state
4. delayed expansion state

In case of it is important to keep the environment of current *.bat or *.cmd script unmodified by whatever Template.bat changes on environment for itself, it is advisable to use setlocal and endlocal.

Run in a command prompt window setlocal /? and endlocal /? for getting displayed the help of these two commands. And read answer on change directory command cd ..not working in batch file after npm install explaining more detailed what these two commands do.

setlocal & cd /D "F:\- Big Packets -\kitterengine\Common" & call Template.bat & endlocal

Now there is only & instead of && used as it is important here that after setlocal is executed the command endlocal is finally also executed.

ONE MORE NOTE

If batch file Template.bat contains the command exit without parameter /B and this command is really executed, the command process is always exited independent on calling hierarchy. So make sure Template.bat contains exit /B or goto :EOF instead of just exit if there is exit used at all in this batch file.

Take a look here: http://longgoldenears.blogspot.com/2007/09/triple-equals-in-javascript.html

The 3 equal signs mean "equality without type coercion". Using the triple equals, the values must be equal in type as well.

0 == false   // true
0 === false  // false, because they are of a different type
1 == "1"     // true, automatic type conversion for value only
1 === "1"    // false, because they are of a different type
null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false

var urlAction = 'whatever.php';
var data = {param1:'value1'};

var $form = $('<form target="_blank" method="POST" action="' + urlAction + '">');
$.each(data, function(k,v){
    $form.append('<input type="hidden" name="' + k + '" value="' + v + '">');
});
$form.submit();

you should know that :

@Before from junit4 goes with @Test : "import org.junit.Test"

AND

@BeforeEach from Junit5 goes with : "import org.junit.jupiter.api.Test"

so make sure you are using the imports from the same version of Junit , otherwise it w'ont Work I guess.

Haskell: difference between . (dot) and $ (dollar sign)

What is the difference between the dot (.) and the dollar sign ($)?. As I understand it, they are both syntactic sugar for not needing to use parentheses.

They are not syntactic sugar for not needing to use parentheses - they are functions, - infixed, thus we may call them operators.

Compose, (.), and when to use it.

(.) is the compose function. So

result = (f . g) x

is the same as building a function that passes the result of its argument passed to g on to f.

h = \x -> f (g x)
result = h x

Use (.) when you don't have the arguments available to pass to the functions you wish to compose.

Right associative apply, ($), and when to use it

($) is a right-associative apply function with low binding precedence. So it merely calculates the things to the right of it first. Thus,

result = f $ g x

is the same as this, procedurally (which matters since Haskell is evaluated lazily, it will begin to evaluate f first):

h = f
g_x = g x
result = h g_x

or more concisely:

result = f (g x)

Use ($) when you have all the variables to evaluate before you apply the preceding function to the result.

We can see this by reading the source for each function.

Read the Source

Here's the source for (.):

-- | Function composition.
{-# INLINE (.) #-}
-- Make sure it has TWO args only on the left, so that it inlines
-- when applied to two functions, even if there is no final argument
(.)    :: (b -> c) -> (a -> b) -> a -> c
(.) f g = \x -> f (g x)

And here's the source for ($):

-- | Application operator.  This operator is redundant, since ordinary
-- application @(f x)@ means the same as @(f '$' x)@. However, '$' has
-- low, right-associative binding precedence, so it sometimes allows
-- parentheses to be omitted; for example:
--
-- >     f $ g $ h x  =  f (g (h x))
--
-- It is also useful in higher-order situations, such as @'map' ('$' 0) xs@,
-- or @'Data.List.zipWith' ('$') fs xs@.
{-# INLINE ($) #-}
($)                     :: (a -> b) -> a -> b
f $ x                   =  f x

Conclusion

Use composition when you do not need to immediately evaluate the function. Maybe you want to pass the function that results from composition to another function.

Use application when you are supplying all arguments for full evaluation.

So for our example, it would be semantically preferable to do

f $ g x

when we have x (or rather, g's arguments), and do:

f . g

when we don't.

Position Relative:

If you specify position:relative, then you can use top or bottom, and left or right to move the element relative to where it would normally occur in the document.

Position Absolute:

When you specify position:absolute, the element is removed from the document and placed exactly where you tell it to go.

Here is a good tutorial http://www.barelyfitz.com/screencast/html-training/css/positioning/ with the sample usage of both position with respective to absolute and relative positioning.

The update from 3.2.x to 3.3.x broke some of the solutions explained here and on other threads because of the change: "Added transforms to improve carousel performance in modern browsers."

If you are using Bootstrap 3.3.x there's a solution here:
http://codepen.io/transportedman/pen/NPWRGq

Basically you need to add the "carousel-fade" class to your carousel so that you have:
<div class="carousel slide carousel-fade">

And then include the following CSS:

/*
  Bootstrap Carousel Fade Transition (for Bootstrap 3.3.x)
  CSS from:       http://codepen.io/transportedman/pen/NPWRGq
  and:            http://stackoverflow.com/questions/18548731/bootstrap-3-carousel-fading-to-new-slide-instead-of-sliding-to-new-slide
  Inspired from:  http://codepen.io/Rowno/pen/Afykb 
*/
.carousel-fade .carousel-inner .item {
  opacity: 0;
  transition-property: opacity;
}

.carousel-fade .carousel-inner .active {
  opacity: 1;
}

.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  left: 0;
  opacity: 0;
  z-index: 1;
}

.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
  opacity: 1;
}

.carousel-fade .carousel-control {
  z-index: 2;
}

/*
  WHAT IS NEW IN 3.3: "Added transforms to improve carousel performance in modern browsers."
  Need to override the 3.3 new styles for modern browsers & apply opacity
*/
@media all and (transform-3d), (-webkit-transform-3d) {
    .carousel-fade .carousel-inner > .item.next,
    .carousel-fade .carousel-inner > .item.active.right {
      opacity: 0;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
    .carousel-fade .carousel-inner > .item.prev,
    .carousel-fade .carousel-inner > .item.active.left {
      opacity: 0;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
    .carousel-fade .carousel-inner > .item.next.left,
    .carousel-fade .carousel-inner > .item.prev.right,
    .carousel-fade .carousel-inner > .item.active {
      opacity: 1;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
}

This is an old post, but I ended up using Peter Lang's thoughts, and did a similar, but yet different approach. Here is what I did:

CREATE OR REPLACE FUNCTION multi_replace(
                        pString IN VARCHAR2
                        ,pReplacePattern IN VARCHAR2
) RETURN VARCHAR2 IS
    iCount  INTEGER;
    vResult VARCHAR2(1000);
    vRule   VARCHAR2(100);
    vOldStr VARCHAR2(50);
    vNewStr VARCHAR2(50);
BEGIN
    iCount := 0;
    vResult := pString;
    LOOP
        iCount := iCount + 1;

        -- Step # 1: Pick out the replacement rules
        vRule := REGEXP_SUBSTR(pReplacePattern, '[^/]+', 1, iCount);

        -- Step # 2: Pick out the old and new string from the rule
        vOldStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 1);
        vNewStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 2);

        -- Step # 3: Do the replacement
        vResult := REPLACE(vResult, vOldStr, vNewStr);

        EXIT WHEN vRule IS NULL;
    END LOOP;

    RETURN vResult;
END multi_replace;

Then I can use it like this:

SELECT  multi_replace(
                        'This is a test string with a #, a $ character, and finally a & character'
                        ,'#=%23/$=%24/&=%25'
        )
FROM dual

This makes it so that I can can any character/string with any character/string.

I wrote a post about this on my blog.

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

Try this one. It's simple, and since it's 2016 I am sure it will work on most browsers.

<textarea id="text" cols="50" rows="5" onkeyup="check()" maxlength="15"></textarea> 
<div><span id="spn"></span> characters left</div>

function check(){
    var string = document.getElementById("url").value
    var left = 15 - string.length;
    document.getElementById("spn").innerHTML = left;
}

This kind of operation is covered under hierarchical indexing. Check out the examples here

When you groupby, you're making new indices. If you also pass a list through .agg(). you'll get multiple columns. I was trying to figure this out and found this thread via google.

It turns out if you pass a tuple corresponding to the exact column you want sorted on.

Try this:

# generate toy data 
ex = pd.DataFrame(np.random.randint(1,10,size=(100,3)), columns=['features', 'AUC', 'recall'])

# pass a tuple corresponding to which specific col you want sorted. In this case, 'mean' or 'AUC' alone are not unique. 
ex.groupby('features').agg(['mean','std']).sort_values(('AUC', 'mean'))

This will output a df sorted by the AUC-mean column only.

Do it the vi way.

    // Find out how many items are in the table

            COUNT(*)
        FROM
            table
    ')->fetchColumn();

    // How many items to list per page
    $limit = 20;

    // How many pages will there be

SuppressFinalize should only be called by a class that has a finalizer. It's informing the Garbage Collector (GC) that this object was cleaned up fully.

The recommended IDisposable pattern when you have a finalizer is:

public class MyClass : IDisposable
{
    private bool disposed = false;

    protected virtual void Dispose(bool disposing)
    {
        if (!disposed)
        {
            if (disposing)
            {
                // called via myClass.Dispose(). 
                // OK to use any private object references
            }
            // Release unmanaged resources.
            // Set large fields to null.                
            disposed = true;
        }
    }

    public void Dispose() // Implement IDisposable
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    ~MyClass() // the finalizer
    {
        Dispose(false);
    }
}

Normally, the CLR keeps tabs on objects with a finalizer when they are created (making them more expensive to create). SuppressFinalize tells the GC that the object was cleaned up properly and doesn't need to go onto the finalizer queue. It looks like a C++ destructor, but doesn't act anything like one.

The SuppressFinalize optimization is not trivial, as your objects can live a long time waiting on the finalizer queue. Don't be tempted to call SuppressFinalize on other objects mind you. That's a serious defect waiting to happen.

Design guidelines inform us that a finalizer isn't necessary if your object implements IDisposable, but if you have a finalizer you should implement IDisposable to allow deterministic cleanup of your class.

Most of the time you should be able to get away with IDisposable to clean up resources. You should only need a finalizer when your object holds onto unmanaged resources and you need to guarantee those resources are cleaned up.

Note: Sometimes coders will add a finalizer to debug builds of their own IDisposable classes in order to test that code has disposed their IDisposable object properly.

public void Dispose() // Implement IDisposable
{
    Dispose(true);
#if DEBUG
    GC.SuppressFinalize(this);
#endif
}

#if DEBUG
~MyClass() // the finalizer
{
    Dispose(false);
}
#endif

This can be done without a function. Code below will convert a UTC time to Mountain time accounting for daylight savings. Adjust all the -6 and -7 numbers to your timezone accordingly (i.e. for EST you would adjust to -4 and -5 respectively)

--Adjust a UTC value, in the example the UTC field is identified as UTC.Field, to account for daylight savings time when converting out of UTC to Mountain time.
CASE
    --When it's between March and November, it is summer time which is -6 from UTC
    WHEN MONTH ( UTC.Field ) > 3 AND MONTH ( UTC.Field ) < 11 
        THEN DATEADD ( HOUR , -6 , UTC.Field )

    WHEN MONTH ( UTC.Field ) = 3
        AND DATEPART ( DAY , UTC.Field ) >= 14 
        THEN

                    AND UTC.Field < '9:00'
                    --Before 2am mountain time so it's winter, -7 hours for Winter daylight time

        THEN 
            --According to the date, it's moved onto Summer daylight, but we need to account for the hours leading up to 2am if it's Sunday
            CASE 
                WHEN DATEPART ( WEEKDAY , UTC.Field ) = 1 
                    AND UTC.Field < '9:00'

And when you want all tables for some reason ?

You can generate these commands in SSMS:

SELECT 
CONCAT('sqlcmd -S ',
'Your(local?)SERVERhere'
,' -d',
'YourDB'
,' -E -s, -W -Q "SELECT * FROM ',
TABLE_NAME,
'" >',
TABLE_NAME,
'.csv') FROM INFORMATION_SCHEMA.TABLES

And get again rows like this

sqlcmd -S ... -d... -E -s, -W -Q "SELECT * FROM table1" >table1.csv
sqlcmd -S ... -d... -E -s, -W -Q "SELECT * FROM table2" >table2.csv
...

There is also option to use better TAB as delimiter, but it would need a strange Unicode character - using Alt+9 in CMD, it came like this ? (Unicode CB25), but works only by copy/paste to command line not in batch.

Here is a way to detect Zombie transaction

SqlTransaction trans = connection.BeginTransaction();

//some db calls here

if (trans.Connection != null) //Detecting zombie transaction
{
  trans.Commit();
}

Decompiling the SqlTransaction class, you will see the following

public SqlConnection Connection
{
  get
  {
    if (this.IsZombied)
      return (SqlConnection) null;
    return this._connection;
  }
}

I notice if the connection is closed, the transOP will become zombie, thus cannot Commit. For my case, it is because I have the Commit() inside a finally block, while the connection was in the try block. This arrangement is causing the connection to be disposed and garbage collected. The solution was to put Commit inside the try block instead.

Just to give a complete answer:

filename_queue = tf.train.string_input_producer(['/Users/HANEL/Desktop/tf.png']) #  list of files to read

reader = tf.WholeFileReader()
key, value = reader.read(filename_queue)

my_img = tf.image.decode_png(value) # use png or jpg decoder based on your files.

init_op = tf.global_variables_initializer()
with tf.Session() as sess:
  sess.run(init_op)

  # Start populating the filename queue.

  coord = tf.train.Coordinator()
  threads = tf.train.start_queue_runners(coord=coord)

  for i in range(1): #length of your filename list
    image = my_img.eval() #here is your image Tensor :) 

  print(image.shape)
  Image.fromarray(np.asarray(image)).show()

  coord.request_stop()
  coord.join(threads)

Or if you have a directory of images you can add them all via this Github source file

@mttk and @salvador-dali: I hope it is what you need

For me, often times this is the only reason some code requires Java 6 to compile. Not sure if it's worth it.

<router-outlet [node]="..."></router-outlet> 

is just invalid. The component added by the router is added as sibling to <router-outlet> and does not replace it.

With pure css it is not possible to make it transparent. You have to use transparent background image like this:

::-webkit-scrollbar-track-piece:start {
    background: transparent url('images/backgrounds/scrollbar.png') repeat-y !important;
}

::-webkit-scrollbar-track-piece:end {
    background: transparent url('images/backgrounds/scrollbar.png') repeat-y !important;
}

my problem (git on macOS) was solved by using sudo git instead of just git in all add and commit commands

You can try this code:

public class MyMatrix {
    Double[][] A = { { 4.00, 3.00 }, { 2.00, 1.00 } };
    Double[][] B = { { -0.500, 1.500 }, { 1.000, -2.0000 } };

    public static Double[][] multiplicar(Double[][] A, Double[][] B) {

        int aRows = A.length;

        Double[][] C = new Double[aRows][bColumns];
        for (int i = 0; i < aRows; i++) {
            for (int j = 0; j < bColumns; j++) {
                C[i][j] = 0.00000;
            }
        }

        for (int i = 0; i < aRows; i++) { // aRow
            for (int j = 0; j < bColumns; j++) { // bColumn
                for (int k = 0; k < aColumns; k++) { // aColumn
                    C[i][j] += A[i][k] * B[k][j];
                }
            }
        }

        return C;

            for (int j = 0; j < 2; j++)
                System.out.print(result[i][j] + " ");
            System.out.println();

Ok, instead of identifying players by name track with sockets through which they have connected. You can have a implementation like

Server

var allClients = [];
io.sockets.on('connection', function(socket) {
   allClients.push(socket);

   socket.on('disconnect', function() {
      console.log('Got disconnect!');

      var i = allClients.indexOf(socket);
      allClients.splice(i, 1);
   });
});

Hope this will help you to think in another way

A very simple solution is to override the toString() method in the Node. Then, you can call print by passing LinkedList's head. You don't need to implement any kind of loop.

Code:

public class LinkedListNode {
    ...

    //New
    @Override
    public String toString() {
        return String.format("Node(%d, next = %s)", data, next);
    }
} 


public class LinkedList {

    public static void main(String[] args) {

        LinkedList l = new LinkedList();
        l.insertFront(0);
        l.insertFront(1);
        l.insertFront(2);
        l.insertFront(3);

        //New
        System.out.println(l.head);
    }
}

I like using ICU4J’s CaseInsensitiveString wrap of the Map key because it takes care of the hash\equals and issue and it works for unicode\i18n.

HashMap<CaseInsensitiveString, String> caseInsensitiveMap = new HashMap<>();
caseInsensitiveMap.put("tschüß", "bye");
caseInsensitiveMap.containsKey("TSCHÜSS"); # true

It is about string concatenation performance. It's potentially significant if your have dense logging statements.

(Prior to SLF4J 1.7) But only two parameters are possible

Because the vast majority of logging statements have 2 or fewer parameters, so SLF4J API up to version 1.6 covers (only) the majority of use cases. The API designers have provided overloaded methods with varargs parameters since API version 1.7.

For those cases where you need more than 2 and you're stuck with pre-1.7 SLF4J, then just use either string concatenation or new Object[] { param1, param2, param3, ... }. There should be few enough of them that the performance is not as important.

for(int i=0;i<str.length();i++)
{
System.out.println(str.charAt(i));
}

If you are using Webdriver then the item you are looking for is Selected.

Often times in the render of the checkbox doesn't actually apply the attribute checked unless specified.

So what you would look for in Selenium Webdriver is this

isChecked = e.findElement(By.tagName("input")).Selected;

As there is no Selected in WebDriver Java API, the above code should be as follows:

isChecked = e.findElement(By.tagName("input")).isSelected();

One simple way to do that is:

String url = "http://test.com/Services/rest/{id}/Identifier"

UriComponents uriComponents = UriComponentsBuilder.fromUriString(url).build();
uriComponents = uriComponents.expand(Collections.singletonMap("id", "1234"));

and then adds the query params.

For non-preemptive system,

waitingTime = startTime - arrivalTime

turnaroundTime = burstTime + waitingTime = finishTime- arrivalTime

startTime = Time at which the process started executing

finishTime = Time at which the process finished executing

You can keep track of the current time elapsed in the system(timeElapsed). Assign all processors to a process in the beginning, and execute until the shortest process is done executing. Then assign this processor which is free to the next process in the queue. Do this until the queue is empty and all processes are done executing. Also, whenever a process starts executing, recored its startTime, when finishes, record its finishTime (both same as timeElapsed). That way you can calculate what you need.

You don't have to restart the PC. Restart IIS instead.

Run -> 'cmd'(as admin) and type "iisreset"

For me, I had to add:

git config --global --unset http.proxy

Basically, you can run:

git config --global -l 

to get the list of all proxy defined, and then use "--unset" to disable them

Loki has both a Factory Method and an Abstract Factory. Both are documented (extensively) in Modern C++ Design, by Andei Alexandrescu. The factory method is probably closer to what you seem to be after, though it's still a bit different (at least if memory serves, it requires you to register a type before the factory can create objects of that type).

A process consists of at least one thread (think of the main function). Multi threaded code will just spawn more threads. Mutexes are used to create locks around shared resources to avoid data corruption / unexpected / unwanted behaviour. Basically it provides for sequential execution in an asynchronous setup - the requirement for which stems from non-const non-atomic operations on shared data structures.

A vivid description of what mutexes would be the case of people (threads) queueing up to visit the restroom (shared resource). While one person (thread) is using the bathroom easing him/herself (non-const non-atomic operation), he/she should ensure the door is locked (mutex), otherwise it could lead to being caught in full monty (unwanted behaviour)

There are two things you need to check:

1. Ensure that your user account has administrator privilege.
2. Disable UAC (User Account Control) as it restricts certain administrative function needed to run a web server.

To ensure that your user account has administrator privilege, run lusrmgr.msc from the Windows Start > Run menu to bring up the Local Users and Groups Windows. Double-click on your user account that appears under Users, and verifies that it is a member of Administrators.

To disable UAC (as an administrator), from Control Panel:

1. Type UAC in the search field in the upper right corner.
2. Click Change User Account Control settings in the search results.
3. Drag the slider down to Never notifyand click OK.

open up the User Accounts window from Control Panel. Click on the Turn User Account Control on or off option, and un-check the checkbox.

Alternately, if you don't want to disable UAC, you will have to install XAMPP in a different folder, outside of C:\Program Files (x86), such as C:\xampp.

Hope this helps.

Use this I think it's better

   *isAngularSite(false);*
    browser.get(crmUrl);


    login.username.sendKeys(username);
    login.password.sendKeys(password);
    login.submit.click();

    *isAngularSite(true);*

For you to use this setting of isAngularSite should put this in your protractor.conf.js here:

        global.isAngularSite = function(flag) {
        browser.ignoreSynchronization = !flag;
        };

session in rails is a hash object. Hence any function available for clearing hash will work with sessions.

session.clear

or if specific keys have to be destroyed:

session.delete(key)

Tested in rails 3.2

added

People have mentioned by session={} is a bad idea. Regarding session.clear, Lobati comments- It looks like you're probably better off using reset_session [than session.clear], as it does some other cleaning up beyond what session.clear does. Internally, reset_session calls session.destroy, which itself calls clear as well some other stuff.

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

Having installed tomcat with brew the solution for me was:

sudo chmod -R 777 /usr/local/Cellar/tomcat/<your_version>

Just adding to Frederic's answer, for example if you call your script as follows:

./myscript.py foo bar

sys.argv[0] would be "./myscript.py" sys.argv[1] would be "foo" and sys.argv[2] would be "bar" ... and so forth.

In your example code, if you call the script as follows ./myscript.py foo , the script's output will be "Hello there foo".

Use SERVER\\ INSTANCE NAME .Using double backslash in my project solved my problem.

You did not specify your operating system, so this is difficult to answer. If you are using a system based on gnu libc, you might be able to use the libc function backtrace().

GCC also has two builtins that can assist you, but which may or may not be implemented fully on your architecture, and those are __builtin_frame_address and __builtin_return_address. Both of which want an immediate integer level (by immediate, I mean it can't be a variable). If __builtin_frame_address for a given level is non-zero, it should be safe to grab the return address of the same level.

I believe if you use delegates, it would work..

$("textarea").on('change paste keyup', function () {
    var currText = $(this).val();
    if (currText.length > 500) {
        var text = $(this).text();
        $(this).text(text.substr(0, 500));
        alert("You have reached the maximum length for this field");
    }
});

One can import the package then consult its help

import statsmodels
help(sm)

At the very bottom of the help there is a section FILE that indicates where this package was installed.

This solution was tested with at least matplotlib (3.1.2) and statsmodels (0.11.1) (python 3.8.2).

Another source of this problem: I found that in Debian 9, the Python httplib2 is hardcoded to insist on TLS v1.0. So any application that uses httplib2 to connect to a server that insists on better security fails with TLSV1_ALERT_PROTOCOL_VERSION.

I fixed it by changing

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)

to

context = ssl.SSLContext()

in /usr/lib/python3/dist-packages/httplib2/__init__.py .

Debian 10 doesn't have this problem.

I had the same issue with setting StatusCode and then Response.End in HandleUnauthorizedRequest method of AuthorizeAttribute

var ctx = filterContext.HttpContext;
ctx.Response.StatusCode = (int)HttpStatusCode.Forbidden;
ctx.Response.End();

If you are using .NET 4.5+, add this line before Response.StatusCode

filterContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;

If you are using .NET 4.0, try SuppressFormsAuthenticationRedirectModule.

ExecutorService WORKER_THREAD_POOL 
  = Executors.newFixedThreadPool(10);
CountDownLatch latch = new CountDownLatch(2);
for (int i = 0; i < 2; i++) {
    WORKER_THREAD_POOL.submit(() -> {
        try {
            // doSomething();
            latch.countDown();
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        }
    });
}

// wait for the latch to be decremented by the two remaining threads
latch.await();

If doSomething() throw some other exceptions, the latch.countDown() seems will not execute, so what should I do?

I would suggest you to use Moment.js http://momentjs.com/

Then you can do:

moment(new Date()).format("YYYY/MM/DD");

Note: you don't actualy need to add new Date() if you want the current TimeDate, I only added it as a reference that you can pass a date object to it. for the current TimeDate this also works:

moment().format("YYYY/MM/DD");

no, there is no way to make array length dynamic in java. you can use ArrayList or other List implementations instead.

import operator
reduce(operator.mul, list, 1)

<form (submit)="onSubmit()">
   <input [(ngModel)]="playerName">
</form>

let playerName: string;
onSubmit() {
  return this.playerName;
}

If you are verifying if a lock is applied on a table or not, try the below query.

SELECT resource_type, resource_associated_entity_id,
    request_status, request_mode,request_session_id,
    resource_description, o.object_id, o.name, o.type_desc 
FROM sys.dm_tran_locks l, sys.objects o
WHERE l.resource_associated_entity_id = o.object_id
    and resource_database_id = DB_ID()

The lookup module of ansible works fine for me. The yml is:

- hosts: test
  vars:
    time: "{{ lookup('pipe', 'date -d \"1 day ago\" +\"%Y%m%d\"') }}"

You can replace any command with date to get result of the command.

The dir wrapper can wrap, any other step, and it all works inside a steps block, for example:

steps {
    sh "pwd"
    dir('your-sub-directory') {
      sh "pwd"
    }
    sh "pwd"
} 

And for all SQL Server versions

SELECT CAST(0.973684210526315789 * 100 AS DECIMAL(18, 2))

try the following example. Image overlay with text on image. demo

<div class="thumbnail">

  <div class="details">

css

.post-content {
    background: rgba(0, 0, 0, 0.7) none repeat scroll 0 0;
    opacity: 0.5;
    top:0;
    left:0;
    min-width: 500px;
    min-height: 500px; 
    position: absolute;
    color: #ffffff; 
}

.thumbnail{
    position:relative;

}
.details {
    position: absolute; 
    z-index: 2; 
    top: 0;
    color: #ffffff; 
}

NB: Should you want the year to be based on some reference date, the code below calculates the dates for the between statement:

declare @referenceTime datetime = getutcdate()
select *
from myTable
where SomeDate 
    between dateadd(year, year(@referenceTime) - 1900, '01-01-1900')                        --1st Jan this year (midnight)
    and dateadd(millisecond, -3, dateadd(year, year(@referenceTime) - 1900, '01-01-1901'))  --31st Dec end of this year (just before midnight of the new year)

Similarly, if you're using a year value, swapping year(@referenceDate) for your reference year's value will work

declare @referenceYear int = 2010
select *
from myTable
where SomeDate 
    between dateadd(year,@referenceYear - 1900, '01-01-1900')                       --1st Jan this year (midnight)
    and dateadd(millisecond, -3, dateadd(year,@referenceYear - 1900, '01-01-1901')) --31st Dec end of this year (just before midnight of the new year)

You may want to look at http://tug.ctan.org/tex-archive/macros/latex/contrib/float/ which allows you to define new floats using \newfloat

I say this because captions are usually applied to floats.

Straight ahead equations (those written with $ ... $, $$ ... $$, begin{equation}...) are in-line objects that do not support \caption.

This can be done using the following snippet just before \begin{document}

\usepackage{float}
\usepackage{aliascnt}
\newaliascnt{eqfloat}{equation}
\newfloat{eqfloat}{h}{eqflts}
\floatname{eqfloat}{Equation}

\newcommand*{\ORGeqfloat}{}
\let\ORGeqfloat\eqfloat
\def\eqfloat{%
  \let\ORIGINALcaption\caption
  \def\caption{%
    \addtocounter{equation}{-1}%
    \ORIGINALcaption
  }%
  \ORGeqfloat
}

and when adding an equation use something like

\begin{eqfloat}
\begin{equation}
f( x ) = ax + b
\label{eq:linear}
\end{equation}
\caption{Caption goes here}
\end{eqfloat}

I haven't done web design for iOS but from what I recall seeing in the WWDC sessions and in documentation, the search bar in Mobile Safari, and navigation bars across the OS, will now automatically resize and shrink to show more of your content.

You can test this in Safari on an iPhone and notice that, when you scroll down to see more contents on a page, the navigation/search bar is hidden automatically.

Perhaps leaving the address bar/navigation bar as is, and not creating a full-screen experience, is what's best. I don't see Apple doing that anytime soon. And at most they are not automatically controlling when the address bar shows/hides.

Sure, you are losing screen real estate, specially on an iPhone 4 or 4S, but there doesn't seem to be an alternative as of Beta 4.

Pass the string and replace space with line break, it gives you desired result.

select replace('shailendra kumar',' ',chr(10)) from dual;

No, it's not allowed. Neither C nor C++ support this feature by default, however TonyK points out (in the comments) that there are extensions to the GNU C compiler that enable this behavior in C.

Here's another:

data[data$Code == "A" | data$Code == "B", ]

It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,

data[Code == "A" | Code == "B", ]

also works, which is one of the really useful things about R.

I've found this to work very well. It uses the .range property of the .autofilter object, which seems to be a rather obscure, but very handy, feature:

Sub copyfiltered()
    ' Copies the visible columns
    ' and the selected rows in an autofilter
    '
    ' Assumes that the filter was previously applied
    '
    Dim wsIn As Worksheet
    Dim wsOut As Worksheet

    Set wsIn = Worksheets("Sheet1")
    Set wsOut = Worksheets("Sheet2")

    ' Hide the columns you don't want to copy
    wsIn.Range("B:B,D:D").EntireColumn.Hidden = True

    'Copy the filtered rows from wsIn and and paste in wsOut
    wsIn.AutoFilter.Range.Copy Destination:=wsOut.Range("A1")
End Sub

datetime2 wins in most aspects except (old apps Compatibility)

1. larger range of values
2. better Accuracy
3. smaller storage space (if optional user-specified precision is specified)

please note the following points

• Syntax
  • datetime2[(fractional seconds precision=> Look Below Storage Size)]
• Precision, scale
  • 0 to 7 digits, with an accuracy of 100ns.
  • The default precision is 7 digits.
• Storage Size
  • 6 bytes for precision less than 3;
  • 7 bytes for precision 3 and 4.
  • All other precision require 8 bytes.
• DateTime2(3) have the same number of digits as DateTime but uses 7 bytes of storage instead of 8 byte (SQLHINTS- DateTime Vs DateTime2)
• Find more on datetime2(Transact-SQL MSDN article)

I recently got this message, too, after I switched the data center location of a web application sending through Google SMTP.

The URL that apparently Google means is: https://support.google.com/mail/answer/78754. At that link, one of the steps is to reset your password. Not coincidentally, I also received an email from google with a subject of "Suspicious sign in prevented" that instructed me to change my password.

After resetting my password, I was back to using Google SMTP as usual.

Because of double print function. I suggest you to use return instead of print inside the function definition.

def lyrics():
    return "The very first line"
print(lyrics())

OR

def lyrics():
    print("The very first line")

You could use the ngSwitch directive:

  <div ng-switch on="selection" >
    <div ng-switch-when="settings">Settings Div</div>
    <span ng-switch-when="home">Home Span</span>
    <span ng-switch-default>default</span>
  </div>

If you don't want the DOM to be loaded with empty divs, you need to create your custom directive using $http to load the (sub)templates and $compile to inject it in the DOM when a certain condition has reached.

This is just an (untested) example. It can and should be optimized:

HTML:

<conditional-template ng-model="element" template-url1="path/to/partial1" template-url2="path/to/partial2"></div>

Directive:

app.directive('conditionalTemplate', function($http, $compile) {
   return {
      restrict: 'E',
      require: '^ngModel',
      link: function(sope, element, attrs, ctrl) {
        // get template with $http
        // check model via ctrl.$viewValue
        // compile with $compile
        // replace element with element.replaceWith()
      }
   };
});

I was having the same issue and this works excellently.

You can use the following code to add column to Datatable at postion 0:

    DataColumn Col   = datatable.Columns.Add("Column Name", System.Type.GetType("System.Boolean"));
    Col.SetOrdinal(0);// to put the column in position 0;

includes() is not supported by most browsers. Your options are either to use

-polyfill from MDN https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/String/includes

or to use

-indexof()

var str = "abcde";
var n = str.indexOf("cd");

Which gives you n=2

This is widely supported.

In addition to what the other answers have said, some databases and systems may require a primary to be present. One situation comes to mind; when using enterprise replication with Informix a PK must be present for a table to participate in replication.

Some times , the text has the same color that background, try with android:background="#CCCCCC" into listview properties and you will can see that.

As firefox does not stringify some object as screen object ; if you want to have the same result such as : JSON.stringify(obj) :

in android 3.1.1 we cant find sync project in tools so C:\Users\AndroidStudioProjects\projectname\.idea\libraries remove the files from libraries and sync again

There are 3 steps:

1. Find which files cause conflicts by command

   git status
   

2. Check the files, in which you would find the conflicts marked like

   <<<<<<<<head
   blablabla
   

3. Change it to the way you want it, then commit with commands

   git add solved_conflicts_files
   git commit -m 'merge msg'
   

What I did is like this.

String person;
String address;
person = your value;
address =your value;
string connString = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
    MySqlConnection conn = new MySqlConnection(connString);
    conn.Open();
    MySqlCommand comm = conn.CreateCommand();
    comm.CommandText = "INSERT INTO room(person,address) VALUES('"+person+"','"+address+"')";
    comm.ExecuteNonQuery();
    conn.Close();

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

If you want to extract the hours, minutes and seconds, try this:

String inputDate = "12:00:00";
String[] split = inputDate.split(":");
int hours = Integer.valueOf(split[0]);
int minutes = Integer.valueOf(split[1]);
int seconds = Integer.valueOf(split[2]);

I would say using tryParse, it'll return 'false' if the uint is to big for an int.
Don't forget that a uint can go much bigger than a int, as long as you going > 0

Golang does not support implicit unpacking of an slice (unlike python) and that is the reason this would not work. Like the examples given above, we would need to workaround it.

One side note:

The implicit unpacking happens for variadic functions in go:

func varParamFunc(params ...int) {

}

varParamFunc(slice1...)

Had the same problem and the solution was to reauthorize the user. Check it here:

<?php

 require_once("src/facebook.php");

  $config = array(
      'appId' => '1424980371051918',
      'secret' => '2ed5c1260daa4c44673ba6fbc348c67d',
      'fileUpload' => false // optional
  );

  $facebook = new Facebook($config);

//Authorizing app:

?>
<a href="<?php echo $facebook->getLoginUrl(); ?>">Login con fb</a>

Saved project and opened on my test enviroment and it worked again. As I did, you can comment your previous code and try.

This gives you the needed results:

string time = "16:23:01";
var result = Convert.ToDateTime(time);
string test = result.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);
//This gives you "04:23:01 PM"  string

You could also use CultureInfo.CreateSpecificCulture("en-US") as not all cultures will display AM/PM.

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

Try this if you are on ubuntu:

sudo apt-get update
sudo apt-get install build-essential libpq-dev libssl-dev openssl libffi-dev zlib1g-dev
sudo apt-get install python3-pip python3.7-dev
sudo apt-get install python3.7

In case you don't have the repository and so it fires a not-found package you first have to install this:

sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
