Your Id property needs to have a setter. However the setter can be private. The [Key] attribute is not necessary if the property is named "Id" as it will find it through the naming convention where it looks for a key with the name "Id".

public Guid Id { get; }              // Will not work
public Guid Id { get; set; }         // Will work
public Guid Id { get; private set; } // Will also work

For me it was a wrong import of a reducer in the rootReducer.js. I imported container instead of reducer file.

Example

import settings from './pages/Settings';

But sure it should be

import settings from './pages/Settings/reducer';

Where settings directory contains following files actions.js, index.js, reducer.js.

To check it you can log reducers arg of the assertReducerShape() function from the redux/es/redux.js.

One fine solution is to implement a Guard with canActivate method. In this scenario you can fetch data from a given api and let user access the component describe in the routing file. In the meantime one can set the data property of the route object and retrieve it in the component.

Let say you have this routing conf:

const routes: Routes = [
    { path: "/:projectName", component: ProjectComponent, canActivate: [ProjectGuard] }
]`

in your guard file you may have:

canActivate(next: ActivatedRouteSnapshot,state: RouterStateSnapshot)
: Observable<boolean> | Promise<boolean> | boolean {
return this.myProjectService.getProject(projectNameFoundElsewhere).pipe(
  map((project) => {
    if (project) {
      next.data = project;
    }
    return !!project;
  }),
);

}`

Then in your component

constructor(private route: ActivatedRoute) {
    this.route.data.subscribe((value) => (this.project = value));
}

This way is a bit different than passing via a service since service keep the value in a behaviorSubject as long as it is not unset. Passing via tha guard make the data available for the current route. I havent check if the children routes keep the data or not.

I was failing to send a body on a DELETE that required one and was getting this message as a result.

This is what's killing you:

task.Wait();

That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...

There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:

private async void Button_Click(object sender, RoutedEventArgs 
{
    Task<List<MyObject>> task = GetResponse<MyObject>("my url");
    var items = await task;
    // Presumably use items here
}

Or just:

private async void Button_Click(object sender, RoutedEventArgs 
{
    var items = await GetResponse<MyObject>("my url");
    // Presumably use items here
}

Now instead of blocking until the task has completed, the Button_Click method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)

Note that I would also rename GetResponse to GetResponseAsync for clarity.

System.ArgumentNullException: Value cannot be null. Parameter name: value

This error message is not very helpful!

You can get this error in many different ways. The error may not always be with the parameter name: value. It could be whatever parameter name is being passed into a function.

As a generic way to solve this, look at the stack trace or call stack:

Test method GetApiModel threw exception: 
System.ArgumentNullException: Value cannot be null.
Parameter name: value
    at Newtonsoft.Json.JsonConvert.DeserializeObject(String value, Type type, JsonSerializerSettings settings)

You can see that the parameter name value is the first parameter for DeserializeObject. This lead me to check my AutoMapper mapping where we are deserializing a JSON string. That string is null in my database.

You can change the code to check for null.

I hate to point out the obvious, but System.IO.FileNotFoundException means the program did not find the file you specified. So what you need to do is check what file your code is looking for in production.

To see what file your program is looking for in production (look at the FileName property of the exception), try these techniques:

• write to a debug log,
• use Visual Studio Attach to Process, or
• use Visual Studio Remote Debugging

Then look at the file system on the machine and see if the file exists. Most likely the case is that it doesn't exist.

hi guys after one day searching on web finally i solve problem with below source code hope to help you

    public UploadResult UploadFile(string  fileAddress)
    {
        HttpClient client = new HttpClient();

        MultipartFormDataContent form = new MultipartFormDataContent();
        HttpContent content = new StringContent("fileToUpload");
        form.Add(content, "fileToUpload");       
        var stream = new FileStream(fileAddress, FileMode.Open);            
        content = new StreamContent(stream);
        var fileName = 
        content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
        {
            Name = "name",
            FileName = Path.GetFileName(fileAddress),                 
        };
        form.Add(content);
        HttpResponseMessage response = null;          

        var url = new Uri("http://192.168.10.236:2000/api/Upload2");
        response = (client.PostAsync(url, form)).Result;          

    }

Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.

And for those of you using an anonymous expression:

await Task.Run(async () =>
{
   SQLLiteUtils slu = new SQLiteUtils();
   await slu.DeleteGroupAsync(groupname);
});

In some cases cleaning the project/solution, physically removing bin/ and obj/ and rebuilding would resolve such errors. This could happen when, for example, some packages and references being installed/added and then removed, leaving some artifacts behind.

It happened to me with Microsoft.Web.Infrastructure: initially, the project didn't require that assembly. After some experiments, the net effect of which was supposed to be zero at the end, I got this exception. Above steps resolved it without the need to install unused dependency.

This is often caused by an attempt to process a null object. An example, trying to empty a Bindable list that is null will trigger the exception:

public class MyViewModel {
    [BindableProperty]
    public virtual IList<Products> ProductsList{ get; set; }

    public MyViewModel ()
    {
        ProductsList.Clear(); // here is the problem
    }
}

This could easily be fixed by checking for null:

if (ProductsList!= null) ProductsList.Clear();

Make sure your .NET version 4.5 or greater

In WPF, you use a DispatcherTimer.

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

For people wondering, this also works for button click. For example:

private void btn_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Test")
        }

private void txb_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)13)
            {
                btn_Click(sender, e);
            }

When pressing Enter in the textfield(txb) in this case it will click the button which will active the MessageBox.

You're right that you should use the Dispatcher to update controls on the UI thread, and also right that long-running processes should not run on the UI thread. Even if you run the long-running process asynchronously on the UI thread, it can still cause performance issues.

It should be noted that Dispatcher.CurrentDispatcher will return the dispatcher for the current thread, not necessarily the UI thread. I think you can use Application.Current.Dispatcher to get a reference to the UI thread's dispatcher if that's available to you, but if not you'll have to pass the UI dispatcher in to your background thread.

Typically I use the Task Parallel Library for threading operations instead of a BackgroundWorker. I just find it easier to use.

For example,

Task.Factory.StartNew(() => 
    SomeObject.RunLongProcess(someDataObject));

where

void RunLongProcess(SomeViewModel someDataObject)
{
    for (int i = 0; i <= 1000; i++)
    {
        Thread.Sleep(10);

        // Update every 10 executions
        if (i % 10 == 0)
        {
            // Send message to UI thread
            Application.Current.Dispatcher.BeginInvoke(
                DispatcherPriority.Normal,
                (Action)(() => someDataObject.ProgressValue = (i / 1000)));
        }
    }
}

I have put this in my partial view:

@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()

in the same kind of situation you describe, and it shows the controller described in the URL (Category for you, Product for me), instead of the actual location of the partial view.

So use this alert instead:

alert('@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()');

I know this is an older subject, however Mocking a MVC application for unit tests is something we do on very regular basis.

I just wanted to add my experiences Mocking a MVC 3 application using Moq 4 after upgrading to Visual Studio 2013. None of the unit tests were working in debug mode and the HttpContext was showing "could not evaluate expression" when trying to peek at the variables.

Turns out visual studio 2013 has issues evaluating some objects. To get debugging mocked web applications working again, I had to check the "Use Managed Compatibility Mode" in Tools=>Options=>Debugging=>General settings.

I generally do something like this:

public static class FakeHttpContext
{
    public static void SetFakeContext(this Controller controller)
    {

        var httpContext = MakeFakeContext();
        ControllerContext context =
        new ControllerContext(
        new RequestContext(httpContext,
        new RouteData()), controller);
        controller.ControllerContext = context;
    }


    private static HttpContextBase MakeFakeContext()
    {
        var context = new Mock<HttpContextBase>();
        var request = new Mock<HttpRequestBase>();
        var response = new Mock<HttpResponseBase>();
        var session = new Mock<HttpSessionStateBase>();
        var server = new Mock<HttpServerUtilityBase>();
        var user = new Mock<IPrincipal>();
        var identity = new Mock<IIdentity>();

        context.Setup(c=> c.Request).Returns(request.Object);
        context.Setup(c=> c.Response).Returns(response.Object);
        context.Setup(c=> c.Session).Returns(session.Object);
        context.Setup(c=> c.Server).Returns(server.Object);
        context.Setup(c=> c.User).Returns(user.Object);
        user.Setup(c=> c.Identity).Returns(identity.Object);
        identity.Setup(i => i.IsAuthenticated).Returns(true);
        identity.Setup(i => i.Name).Returns("admin");

        return context.Object;
    }


}

And initiating the context like this

FakeHttpContext.SetFakeContext(moController);

And calling the Method in the controller straight forward

long lReportStatusID = -1;
var result = moController.CancelReport(lReportStatusID);

there.

I am also developing a serial port testing tool using WPF, and I'd like to share some experience of mine.

I think you should refactor your source code according to MVVM design pattern.

At the beginning, I met the same problem as you met, and I solved it using this code:

new Thread(() => 
{
    while (...)
    {
        SomeTextBox.Dispatcher.BeginInvoke((Action)(() => SomeTextBox.Text = ...));
    }
}).Start();

This works, but is too ugly. I have no idea how to refactor it, until I saw this: http://www.codeproject.com/Articles/165368/WPF-MVVM-Quick-Start-Tutorial

This is a very kindly step-by-step MVVM tutorial for beginners. No shiny UI, no complex logic, only the basic of MVVM.

You can do this:

public int Property { get { ... } private set { ... } }

isn't the same as the Winform and Webform way?

listBox1.Items.Clear();

No, you'll have to specify the authentication method to use (typically "Basic") and the authentication realm. See http://en.wikipedia.org/wiki/Basic_access_authentication for an example request and response.

You might also want to read RFC 2617 - HTTP Authentication: Basic and Digest Access Authentication.

To answer the initial question "how to properly pass routedata to error controller?":

IController errorController = new ErrorController();
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));

Then in your ErrorController class, implement a function like this:

[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Error(Exception exception)
{
    return View("Error", exception);
}

This pushes the exception into the View. The view page should be declared as follows:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<System.Exception>" %>

And the code to display the error:

<% if(Model != null) { %>  <p><b>Detailed error:</b><br />  <span class="error"><%= Helpers.General.GetErrorMessage((Exception)Model, false) %></span></p> <% } %>

Here is the function that gathers the all exception messages from the exception tree:

    public static string GetErrorMessage(Exception ex, bool includeStackTrace)
    {
        StringBuilder msg = new StringBuilder();
        BuildErrorMessage(ex, ref msg);
        if (includeStackTrace)
        {
            msg.Append("\n");
            msg.Append(ex.StackTrace);
        }
        return msg.ToString();
    }

    private static void BuildErrorMessage(Exception ex, ref StringBuilder msg)
    {
        if (ex != null)
        {
            msg.Append(ex.Message);
            msg.Append("\n");
            if (ex.InnerException != null)
            {
                BuildErrorMessage(ex.InnerException, ref msg);
            }
        }
    }

I know this thread is 10 years old but the problem still exists....

The original question was 'to retrieve' the selected item. I also needed to "get" the selected item in my viewmodel (not set it). Of all the answers in this thread, the one by 'Wes' is the only one that approaches the problem differently: If you can use the 'Selected Item' as a target for databinding use it as a source for databinding. Wes did it to another view property, I will do it to a viewmodel property:

We need two things:

• Create a dependency property in the viewmodel (in my case of type 'MyObject' as my treeview is bound to object of the 'MyObject' type)
• Bind from the Treeview.SelectedItem to this property in the View's constructor (yes that is code behind but, it's likely that you will init your datacontext there as well)

Viewmodel:

public static readonly DependencyProperty SelectedTreeViewItemProperty = DependencyProperty.Register("SelectedTreeViewItem", typeof(MyObject), typeof(MyViewModel), new PropertyMetadata(OnSelectedTreeViewItemChanged));

    private static void OnSelectedTreeViewItemChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        (d as MyViewModel).OnSelectedTreeViewItemChanged(e);
    }

    private void OnSelectedTreeViewItemChanged(DependencyPropertyChangedEventArgs e)
    {
        //do your stuff here
    }

    public MyObject SelectedWorkOrderTreeViewItem
    {
        get { return (MyObject)GetValue(SelectedTreeViewItemProperty); }
        set { SetValue(SelectedTreeViewItemProperty, value); }
    }

View constructor:

Binding binding = new Binding("SelectedItem")
        {
            Source = treeView, //name of tree view in xaml
            Mode = BindingMode.OneWay
        };

        BindingOperations.SetBinding(DataContext, MyViewModel.SelectedTreeViewItemProperty, binding);

As much as I love XAML, for this kinds of tasks I switch to code behind. Attached behaviors are a good pattern for this. Keep in mind, Expression Blend 3 provides a standard way to program and use behaviors. There are a few existing ones on the Expression Community Site.

Here is the extension method to load an image from URI:

public static BitmapImage GetBitmapImage(
    this Uri imageAbsolutePath,
    BitmapCacheOption bitmapCacheOption = BitmapCacheOption.Default)
{
    BitmapImage image = new BitmapImage();
    image.BeginInit();
    image.CacheOption = bitmapCacheOption;
    image.UriSource = imageAbsolutePath;
    image.EndInit();

    return image;
}

Sample of use:

Uri _imageUri = new Uri(imageAbsolutePath);
ImageXamlElement.Source = _imageUri.GetBitmapImage(BitmapCacheOption.OnLoad);

Simple as that!

another way to do it:

<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                    <StackPanel>
                        <Image Source="{Binding ProductImage,RelativeSource={RelativeSource TemplatedParent}}" Stretch="Fill" Width="65" Height="85"/>
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        <Button x:Name="myButton" Width="40" Height="10">
                            <Popup Width="100" Height="70" IsOpen="{Binding ElementName=myButton,Path=IsMouseOver, Mode=OneWay}">
                                <StackPanel Background="Yellow">
                                    <ItemsControl ItemsSource="{Binding Produkt.SubProducts}"/>
                                </StackPanel>
                            </Popup>
                        </Button>
                    </StackPanel>
                </Border>

DependencyObject parent = ExVisualTreeHelper.FindVisualParent<UserControl>(this);

What @Bogdan Maxim said. Or change to use InProc if you're not using an external sesssion state server.

<sessionState mode="InProc" timeout="20" cookieless="AutoDetect" />

Look here for more info on the SessionState directive.

Both JBoss and Tomcat are Java servlet application servers, but JBoss is a whole lot more. The substantial difference between the two is that JBoss provides a full Java Enterprise Edition (Java EE) stack, including Enterprise JavaBeans and many other technologies that are useful for developers working on enterprise Java applications.

Tomcat is much more limited. One way to think of it is that JBoss is a Java EE stack that includes a servlet container and web server, whereas Tomcat, for the most part, is a servlet container and web server.

Here is an example of concatenation operator:

architecture EXAMPLE of CONCATENATION is

begin
   Z_BUS <= A_BIT & B_BIT & C_BIT & D_BIT;
end EXAMPLE;

with the massive remit by google to stop both spam and the scraping of their search database, I believe that this is part of the effort to track bots etc.

some simple anti bot pseudo could go like this.

On GET (google.*) Save RemoteEndPoint
{
    If RemoteEndPoint GETs (clients1.google.com/generate_204) Then
        Set botAlert_stage1 = false;
    Else
        Set botAlert_stage1 = true;
    End If
}

I also believe that the latest google frontpage 'theme' is also a new tool to help with the anti spam/bot activity.

** NOTE ** ipv6.google.com also includes this measure.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

Java does not provide a way to manually suggest that a method should be inlined. As @notnoop says in the comments, the inlining is typically done by the JVM at execution time.

A quote from the documentation:

• Source: Microsoft, Windows XP Professional Product Documentation, Command shell overview
• Also: An A-Z Index of Windows CMD commands

Using multiple commands and conditional processing symbols

You can run multiple commands from a single command line or script using conditional processing symbols. When you run multiple commands with conditional processing symbols, the commands to the right of the conditional processing symbol act based upon the results of the command to the left of the conditional processing symbol.

For example, you might want to run a command only if the previous command fails. Or, you might want to run a command only if the previous command is successful.

You can use the special characters listed in the following table to pass multiple commands.

• & [...]
command1 & command2
  Use to separate multiple commands on one command line. Cmd.exe runs the first command, and then the second command.

• && [...]
command1 && command2
  Use to run the command following && only if the command preceding the symbol is successful. Cmd.exe runs the first command, and then runs the second command only if the first command completed successfully.

• || [...]
command1 || command2
  Use to run the command following || only if the command preceding || fails. Cmd.exe runs the first command, and then runs the second command only if the first command did not complete successfully (receives an error code greater than zero).

• ( ) [...]
(command1 & command2)
  Use to group or nest multiple commands.

• ; or ,
command1 parameter1;parameter2
  Use to separate command parameters.

Don't know another way of checking this, but this: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#getProperties()" implies "java.version" is a standard system property so I'd expect it to work with other JVMs.

As far as installing a custom plugin there is a good walkthrough on GitHub for the rest2mobile library that could be used for any plugin.

Basically the steps are as follows:

1. Run Android Studio.
2. From the menu bar, select Android Studio > Preferences.
3. Under IDE Settings, click Plugins and then click Install plugin from disk.
4. Navigate to the folder where you downloaded the plugin and double-click it.
5. Restart Android Studio.

Try not to do DOM manipulation by referring the DOM directly, it will have lot of performance issue, also event handling becomes more tricky when we try to access DOM directly, instead use data and directives to manipulate the DOM.

This will give you more control over the manipulation, also you will be able to manage functionalities in the modular format.

input[type="text"]
{
    width:200px
}

Try this code

$('window').scrollDown(function(){$(#div).hide()});

$('window').scrollUp(function(){ $(#div).show() });

I would like to return two values from a function in two separate variables.

What would you expect it to look like on the calling end? You can't write a = select_choice(); b = select_choice() because that would call the function twice.

Values aren't returned "in variables"; that's not how Python works. A function returns values (objects). A variable is just a name for a value in a given context. When you call a function and assign the return value somewhere, what you're doing is giving the received value a name in the calling context. The function doesn't put the value "into a variable" for you, the assignment does (never mind that the variable isn't "storage" for the value, but again, just a name).

When i tried to to use return i, card, it returns a tuple and this is not what i want.

Actually, it's exactly what you want. All you have to do is take the tuple apart again.

And i want to be able to use these values separately.

So just grab the values out of the tuple.

The easiest way to do this is by unpacking:

a, b = select_choice()

Dim ipAddress As IPAddress
Dim ipHostInfo As IPHostEntry = Dns.Resolve(Dns.GetHostName())
ipAddress = ipHostInfo.AddressList(0)

After much searching for a solution to this very issue, this particular page seemed to have the most beef...however, nothing quite fit exactly, so I took the old-fashioned way and just parsed the stuff out I wanted out. Hope this helps someone. (Note: this also removes the SOAP or similar envelope stuff.)

I do it in simpler way - first install jquery by npm in console: npm install jquery -S and then in component file I just write: let $ = require('.../jquery.min.js') and it works! Here full example from some my code:

import { Component, Input, ElementRef, OnInit } from '@angular/core';
let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');

@Component({
    selector: 'departments-connections-graph',
    templateUrl: './departmentsConnectionsGraph.template.html',
})

export class DepartmentsConnectionsGraph implements OnInit {
    rootNode : any;
    container: any;

    constructor(rootNode: ElementRef) {
      this.rootNode = rootNode; 
    }

    ngOnInit() {
      this.container = $(this.rootNode.nativeElement).find('.departments-connections-graph')[0];
      console.log({ container : this.container});
      ...
    }
}

In teplate I have for instance:

<div class="departments-connections-graph">something...</div>

EDIT

Alternatively instead of using:

let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');

use

declare var $: any;

and in your index.html put:

<script src="assets/js/jquery-2.1.1.js"></script>

This will initialize jquery only once globaly - this is important for instance for use modal windows in bootstrap...

I needed to copy a table from one database another database. For anyone using a GUI like Sequel Ace you can right click table and click 'copy create table syntax' and run that query (you can edit the query, e.g. change table name, remove foreign keys, add/remove columns if desired)

I use Gitlab-CI to build the image and then deploy it directly to GCK. If use a neat little trick to achieve a rolling update without changing any real settings of the container, which is changing a label to the current commit-short-sha.

My command looks like this:

kubectl patch deployment my-deployment -p "{\"spec\":{\"template\":{\"metadata\":{\"labels\":{\"build\":\"$CI_COMMIT_SHORT_SHA\"}}}}}}"

Where you can use any name and any value for the label as long as it changes with each build.

Have fun!

The following code will work:

private WebView mWebView;
final Activity activity = this;

// private Button b;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setDomStorageEnabled(true);
    mWebView.setWebChromeClient(new WebChromeClient() {
        public void onProgressChanged(WebView view, int progress) {
            activity.setProgress(progress * 1000);
        }
    });

    mWebView.loadUrl("file:///android_asset/raw/NewFile1.html");
}

puts adds a new line to the end of each argument if there is not one already.

print does not add a new line.

For example:

puts [[1,2,3], [4,5,nil]] Would return:

1
2
3
4
5

Whereas print [[1,2,3], [4,5,nil]] would return:

[[1,2,3], [4,5,nil]]

Notice how puts does not output the nil value whereas print does.

Stop thinking of your application as a monolithic application. It is a set of UI screens that the user can interact with your "application", and "functions" provided via Android services.

Not knowing what your mysterious app "does" is not really important. Let's assume it tunnels into some super secure corporate intranet, performing some monitoring or interaction and stays logged in until the user "quits the application". Because your IT department commands it, users must be very conscious of when they are IN or OUT of the intranet. Hence your mindset of it being important for users to "quit".

This is simple. Make a service that puts an ongoing notification in the notification bar saying "I'm in the intranet, or I am running". Have that service perform all the functionality that you need for your application. Have activities that bind to that service to allow your users to access the bits of UI they need to interact with your "application". And have an Android Menu -> Quit (or logout, or whatever) button that tells the service to quit, then closes the activity itself.

This is, for all intents and purposes exactly what you say you want. Done the Android way. Look at Google Talk or Google Maps Navigation for examples of this "exit" is possible mentality. The only difference is that pressing back button out of your activity might leave your UNIX process lying in wait just in case the user wants to revive your application. This is really no different than a modern operating system that caches recently accessed files in memory. After you quit your windows program, most likely resources that it needed are still in memory, waiting to be replaced by other resources as they are loaded now that they are no longer needed. Android is the same thing.

I really don't see your problem.

You need to go one level deeper in what you are retrieving.

Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects("MyTable")
MsgBox tbl.Range.Rows.Count
MsgBox tbl.HeaderRowRange.Rows.Count
MsgBox tbl.DataBodyRange.Rows.Count
Set tbl = Nothing

More information at:

ListObject Interface
ListObject.Range Property
ListObject.DataBodyRange Property
ListObject.HeaderRowRange Property

You state in the comments that the returned JSON is this:

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

You're telling Gson that you have an array of Post objects:

List<Post> postsList = Arrays.asList(gson.fromJson(reader,
                    Post[].class));

You don't. The JSON represents exactly one Post object, and Gson is telling you that.

Change your code to be:

Post post = gson.fromJson(reader, Post.class);

For several cases, or even just a few cases involving a lot of criteria, consider using a switch.

switch( true ){

    case ( !empty($youtube) && !empty($link) ):{
        // Nothing is empty...
        break;
    }

    case ( !empty($youtube) && empty($link) ):{
        // One is empty...
        break;
    }

    case ( empty($youtube) && !empty($link) ):{
        // The other is empty...
        break;
    }

    case ( empty($youtube) && empty($link) ):{
        // Everything is empty
        break;
    }

    default:{
        // Even if you don't expect ever to use it, it's a good idea to ALWAYS have a default.
        // That way if you change it, or miss a case, you have some default handler.
        break;
    }

}

If you have multiple cases that require the same action, you can stack them and omit the break; to flowthrough. Just maybe put a comment like /*Flowing through*/ so you're explicit about doing it on purpose.

Note that the { } around the cases aren't required, but they are nice for readability and code folding.

More about switch: http://php.net/manual/en/control-structures.switch.php

You can use the below method, which will take your target URL as the only input (Don't forget http://)

void GoToURL(String url){
    Uri uri = Uri.parse(url);
    Intent intent= new Intent(Intent.ACTION_VIEW,uri);
    startActivity(intent);
}

In fact, this is a "how to" subject. So, here is the reference implementation:

    public class BOX
    {
        double height, length, breadth;

        public static bool operator == (BOX b1, BOX b2)
        {
            if ((object)b1 == null)
                return (object)b2 == null;

            return b1.Equals(b2);
        }

        public static bool operator != (BOX b1, BOX b2)
        {
            return !(b1 == b2);
        }

UPDATE: the cast to (object) in the operator == implementation is important, otherwise, it would re-execute the operator == overload, leading to a stackoverflow. Credits to @grek40.

This (object) cast trick is from Microsoft String == implementaiton. SRC: https://github.com/Microsoft/referencesource/blob/master/mscorlib/system/string.cs#L643

Managed code is what C#.Net, VB.Net, F#.Net etc compilers create. It runs on the CLR, which among other things offers services like garbage collection, and reference checking, and much more. So think of it as, my code is managed by the CLR.

On the other hand, unmanaged code compiles straight to machine code. It doesn't manage by CLR.

Actually, ojdbc14.jar doesn't really say anything about the real version of the driver (see JDBC Driver Downloads), except that it predates Oracle 11g. In such situation, you should provide the exact version.

Anyway, I think you'll find some explanation in What is going on with DATE and TIMESTAMP? In short, they changed the behavior in 9.2 drivers and then again in 11.1 drivers.

This might explain the differences you're experiencing (and I suggest using the most recent version i.e. the 11.2 drivers).

Try this

SELECT * FROM messages where id in (SELECT max(id) FROM messages GROUP BY from_id ) order by id desc

The only thing I can add to Stephan202's answer is a recommendation that you take a look at David Beazley's PyCon '08 presentation "Generator Tricks for Systems Programmers," which is the best single explanation of the how and why of generators that I've seen anywhere. This is the thing that took me from "Python looks kind of fun" to "This is what I've been looking for." It's at http://www.dabeaz.com/generators/.

If you run a script directly e.g., ./xx.py and your script has no shebang such as #!/usr/bin/env python at the very top then your shell may execute it as a shell script. POSIX says:

If the execl() function fails due to an error equivalent to the [ENOEXEC] error defined in the System Interfaces volume of POSIX.1-2008, the shell shall execute a command equivalent to having a shell invoked with the pathname resulting from the search as its first operand, with any remaining arguments passed to the new shell, except that the value of "$0" in the new shell may be set to the command name. If the executable file is not a text file, the shell may bypass this command execution. In this case, it shall write an error message, and shall return an exit status of 126.

Note: you may get ENOEXEC if your text file has no shebang.

Without the shebang, you shell tries to run your Python script as a shell script that leads to the error: import: command not found.

Also, if you run your script as python xx.py then you do not need the shebang. You don't even need it to be executable (+x). Your script is interpreted by python in this case.

On Windows, shebang is not used unless pylauncher is installed. It is included in Python 3.3+.

You can insert an image that looks like a button. Then attach a script to the image.

• INSERT menu
• Image

You can insert any image. The image can be edited in the spreadsheet

Assign a function name to an image:

If your problem is same as mine where you just want to reset the column headers from 0 to column size. Do

df = pd.DataFrame(df.values);

EDIT:

Not a good idea if you have heterogenous data types. Better just use

df.columns = range(len(df.columns))

Warning: Answers above only work most of the time!

In jQuery version 3.3.1 (haven't tested other versions)

$("#myList li").length; 

works only if your list items don't wrap. If your items wrap in the list then this code counts the number of lines occupied not the number of <li> elements.

$("#myList").children().length;

gets the actual number of <li> elements in your list not the number of lines that are occupied.

You don't need jQuery for this. You can use JavaScript's .childNodes.length.

Just make sure to subtract 1 if you don't want to include the default text node (which is empty by default). Thus, you'd use the following:

var count = elem.childNodes.length - 1;

I am going with the answer from here:

bash -c 'while [ 0 ]; do <your command>; sleep 5; done'

But you're really better off installing watch as this isn't very clean...

according to me this answer is useful for you:

def casear(a,key):
str=""
if key>26:
    key%=26
for i in range(0,len(a)):
    if a[i].isalpha():
        b=ord(a[i])
        b+=key
        #if b>90:                   #if upper case letter ppear in your string
        #    c=b-90                 #if upper case letter ppear in your string
        #    str+=chr(64+c)         #if upper case letter ppear in your string
        if b>122:
            c=b-122
            str+=chr(96+c)
        else:
            str+=chr(b)
    else:
        str+=a[i]
print str

a=raw_input()
key=int(input())
casear(a,key)

This function shifts all letter to right according to given key.

If you have a string like this: '123456' and you want a list of integers like this: [1,2,3,4,5,6], use this:

>>>s = '123456'    
>>>list1 = [int(i) for i in list(s)]
>>>print(list1)

[1,2,3,4,5,6]

or if you want a list of strings like this: ['1','2','3','4','5','6'], use this:

>>>s = '123456'    
>>>list1 = list(s)
>>>print(list1)

['1','2','3','4','5','6']

MSBuild is your friend.

Microsoft has listened to the cry for supporting installers (MSI) in Visual Studio and release the Visual Studio Installer Projects Extension. You can now create installers in VS2013, download the extension here from the visualstudiogallery.

jQuery Tools and jQuery UI get in conflict because they both declare jQuery.tabs and the conflict prevents the second one (in this case jQuery UI) from being loaded. This is the reason why you get a draggable is not a function error.

A solution to this problem is to create a custom version of jQuery Tools (from here) without the tabs functionality.

Informations about the conflict found here: Can JQuery UI and JQuery tools work together?

EDIT As jirassimok has mentioned below my function will change the data in place, after that it runs a lot faster in timeit. This causes the good results. It's some kind of cheating. Sorry for your inconvenience.

I found a faster method for ReLU with numpy. You can use the fancy index feature of numpy as well.

fancy index:

20.3 ms ± 272 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

>>> x = np.random.random((5,5)) - 0.5 
>>> x
array([[-0.21444316, -0.05676216,  0.43956365, -0.30788116, -0.19952038],
       [-0.43062223,  0.12144647, -0.05698369, -0.32187085,  0.24901568],

>>> x[x<0]=0
>>> x
array([[ 0.        ,  0.        ,  0.43956365,  0.        ,  0.        ],
       [ 0.        ,  0.12144647,  0.        ,  0.        ,  0.24901568],
       [ 0.06785385,  0.        ,  0.        ,  0.3736868 ,  0.24832288],
       [ 0.47085262,  0.        ,  0.46904916,  0.        ,  0.        ],
       [ 0.08381359,  0.        ,  0.        ,  0.        ,  0.        ]])

Here is my benchmark:

import numpy as np
x = np.random.random((5000, 5000)) - 0.5
print("max method:")
%timeit -n10 np.maximum(x, 0)
print("max inplace method:")
%timeit -n10 np.maximum(x, 0,x)
print("multiplication method:")
%timeit -n10 x * (x > 0)
print("abs method:")
%timeit -n10 (abs(x) + x) / 2
print("fancy index:")
%timeit -n10 x[x<0] =0

max method:
241 ms ± 3.53 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
max inplace method:
38.5 ms ± 4 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
multiplication method:
162 ms ± 3.1 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
abs method:
181 ms ± 4.18 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
fancy index:
20.3 ms ± 272 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

1. Install request module, using npm install request

2. In code:

   var request = require('request');
   var data = '{ "request" : "msg", "data:" {"key1":' + Var1 + ', "key2":' + Var2 + '}}';
   var json_obj = JSON.parse(data);
   request.post({
       headers: {'content-type': 'application/json'},
       url: 'http://localhost/PhpPage.php',
       form: json_obj
   }, function(error, response, body){
     console.log(body)
   });
   

The "Application not installed" error can also occur if the app has been installed to or moved to the SD card, and then the USB cable has been connected, causing the SD card to unmount.

Turning off USB storage or moving the app back to internal storage would fix the issue in this case.

Refer the below code it worked for me.But it will affect all your controls color.

 <!-- In your style.xml file -->
    <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
            <!--EditText hint color-->
            <item name="android:textColorHint">@color/default_app_white</item>
           <!-- TextInputLayout text color-->
            <item name="colorControlActivated">@color/default_app_green</item>
            <!-- EditText line color when EditText on-focus-->
            <item name="colorControlHighlight">@color/default_app_green</item>
            <!-- EditText line color when EditText  in un-focus-->
            <item name="colorControlNormal">@color/default_app_white</item>
        </style>

You can also install any of the Hardware IO Tools without installing XCode itself. Simply visit Apple's Download Center and search for "Hardware IO".

I've used the following approach successfully in all major browsers including Chrome:

<!DOCTYPE html>

<html>
  <head>
    <meta http-equiv="content-type" content="text/html;charset=UTF-8" />
    <title>Paginated HTML</title>
    <style type="text/css" media="print">
      div.page
      {
        page-break-after: always;
        page-break-inside: avoid;
      }
    </style>
  </head>
  <body>
    <div class="page">
      <h1>This is Page 1</h1>
    </div>
    <div class="page">
      <h1>This is Page 2</h1>
    </div>
    <div class="page">
      <h1>This is Page 3</h1>
    </div>
  </body>
</html>

This is a simplified example. In the real code, each page div contains many more elements.

• For your cookies, see this answer.
• For PHP's own session cookie (PHPSESSID, by default), see @richie's answer

The setcookie() and setrawcookie() functions, introduced the httponly parameter, back in the dark ages of PHP 5.2.0, making this nice and easy. Simply set the 7th parameter to true, as per the syntax

Function syntax simplified for brevity

setcookie(    $name, $value, $expire, $path, $domain, $secure, $httponly )
setrawcookie( $name, $value, $expire, $path, $domain, $secure, $httponly )

In PHP < 8, specify NULL for parameters you wish to remain as default.

In PHP >= 8 you can benefit from using named parameters. See this question about named params.

setcookie( $name, $value, httponly:true )

It is also possible using the older, lower-level header() function:

header( "Set-Cookie: name=value; httpOnly" );

You may also want to consider if you should be setting the secure parameter.

That DateTime format is actually ISO 8601 DateTime. JSON does not specify any particular format for dates/times. If you Google a bit, you will find plenty of implementations to parse it in Java.

Here's one

If you are open to using something other than Java's built-in Date/Time/Calendar classes, I would also suggest Joda Time. They offer (among many things) a ISODateTimeFormat to parse these kinds of strings.

I've changed the java proxy settings to direct connection - and it works.

If you're using EF and Publish Profiles, you could have a blank connection string entry in your publish profile. Annoying but entirely possible.

chaining is always best :D

String str = "somethingPutHere";
Character[] c = ArrayUtils.toObject(str.toCharArray());

You can use .filter on a jQuery object that was created from the response:

success: function(data){
    //Create jQuery object from the response HTML.
    var $response=$(data);

    //Query the jQuery object for the values
    var oneval = $response.filter('#one').text();
    var subval = $response.filter('#sub').text();
}

There is a clear distinction between the usage of ' ' and " ".

When ' ' is used around anything, there is no "transformation or translation" done. It is printed as it is.

With " ", whatever it surrounds, is "translated or transformed" into its value.

By translation/ transformation I mean the following: Anything within the single quotes will not be "translated" to their values. They will be taken as they are inside quotes. Example: a=23, then echo '$a' will produce $a on standard output. Whereas echo "$a" will produce 23 on standard output.

From other post:

    find /c "string" file >NUL
    if %errorlevel% equ 1 goto notfound
        echo found
    goto done
    :notfound
        echo notfound
    goto done
    :done

Use the /i switch when you want case insensitive checking:

    find /i /c "string" file >NUL

Or something like: if not found write to file.

    find /c "%%P" file.txt  || ( echo %%P >> newfile.txt )

Or something like: if found write to file.

    find /c "%%P" file.txt  && ( echo %%P >> newfile.txt )

Or something like:

    find /c "%%P" file.txt  && ( echo found ) || ( echo not found )

For those looking for a C# workaround:

If you need for some reason to have the "AutoGeneratedColumns" enabled, one thing you can do is to specify all the columns's width except the ones you want to be auto resized (it will not take the remaining space, but it will resize to the cell's content).

Example (dgShopppingCart is my DataGrid):

dgShoppingCart.Columns[0].Visibility = Visibility.Hidden; 
dgShoppingCart.Columns[1].Header = "Qty";
dgShoppingCart.Columns[1].Width = 100;
dgShoppingCart.Columns[2].Header = "Product Name"; /*This will be resized to cell content*/
dgShoppingCart.Columns[3].Header = "Price";
dgShoppingCart.Columns[3].Width = 100;
dgShoppingCart.Columns[4].Visibility = Visibility.Hidden; 

For me it works as a workaround because I needed to have the DataGrid resized when the user maximize the Window.

How I fixed this issue was I manually changed the code behind (from the menu View/code). The section below should have as many number of pairs <TablixMember> </TablixMember> as the number of rows are in the tablix. In my case I had more pairs <TablixMember> </TablixMember>than the number of rows in the tablix. Also if you go to "Advanced mode" (to the right of "Column Groups") the number of static lines behind the "Row groups" should be equal to the number of rows in the tablix. The way to make it equal is changing the code.

<TablixRowHierarchy>
      <TablixMembers>
        <TablixMember>
          <KeepWithGroup>After</KeepWithGroup>
          <RepeatOnNewPage>true</RepeatOnNewPage>
        </TablixMember>
        <TablixMember>
          <Group Name="Detail" />
        </TablixMember>
      </TablixMembers>
    </TablixRowHierarchy>

git clone your-repo tmp && mv tmp/.git . && rm -rf tmp && git reset --hard

To install a specific package:

conda install <pkg>=<version>

eg:

conda install matplotlib=1.4.3

The PHP.net recommended way of setting the charset is now this:

mysqli_set_charset('utf8')

I just had a very similar issues with gradle builds / adding .jar library. I got it working by a combination of :

1. Moving the libs folder up to the root of the project (same directory as 'src'), and adding the library to this folder in finder (using Mac OS X)
2. In Android Studio, Right-clicking on the folder to add as library
3. Editing the dependencies in the build.gradle file, adding compile fileTree(dir: 'libs', include: '*.jar')}

BUT more importantly and annoyingly, only hours after I get it working, Android Studio have just released 0.3.7, which claims to have solved a lot of gradle issues such as adding .jar libraries

Hope this helps people!

Go to the Customize section on Bootstrap site and choose the size you prefer. You'll have to set @gridColumnWidth and @gridGutterWidth variables.

For example: @gridColumnWidth = 65px and @gridGutterWidth = 20px results on a 1000px layout.

Then download it.

find /PATH/TO/YOUR/FILES -name NAME.EXT -exec cp -rfp {} /DST_DIR \;

 grouped=df.groupby(['Team','Year'])['W'].count().reset_index()

 team_wins_df=pd.DataFrame(grouped)
 team_wins_df=team_wins_df.rename({'W':'Wins'},axis=1)
 team_wins_df['Wins']=team_wins_df['Wins'].astype(np.int32)
 team_wins_df.reset_index()
 print(team_wins_df)

It is possible!

This appears to override browser settings. Hope it works for you.

According to VBA help on SET statement it sets a reference to an object.so if you change a property the actual object will also changes.

Dim newObj as Object
Set var1=Object1(same type as Object)
Set var2=Object1(same type as Object)
Set var3=Object1(same type as Object)
Set var4=Object1(same type as Object)
Var1.property1=NewPropertyValue

the other Vars properties also changes,so:

Var1.property1=Var2.property1=Var3.property1=Var4.property1=Object1.Property1=NewpropertyValue`

actualy all vars are the same!

Try this

cd repo1

This will remove all the directories except the ones mentioned, preserving history only for these directories

git filter-branch --index-filter 'git rm --ignore-unmatch --cached -qr -- . && git reset -q $GIT_COMMIT -- dir1/ dir2/ dir3/ ' --prune-empty -- --all

Now you can add your new repo in your git remote and push it to that

git remote remove origin <old-repo>

git remote add origin <new-repo>

git push origin <current-branch>

add -f to overwrite

Here is a simple program that displays the camera feed in a cv2.namedWindow and will take a snapshot when you hit SPACE. It will also quit if you hit ESC.

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    if not ret:
        print("failed to grab frame")
        break
    cv2.imshow("test", frame)

    k = cv2.waitKey(1)
    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

I think this should answer your question for the most part. If there is any line of it that you don't understand let me know and I'll add comments.

If you need to grab multiple images per press of the SPACE key, you will need an inner loop or perhaps just make a function that grabs a certain number of images.

Note that the key events are from the cv2.namedWindow so it has to have focus.

right way is

import datetime
isinstance(x, datetime.date)

When I try this on my machine it works fine. You need to look into why datetime.date is not a class. Are you perhaps masking it with something else? or not referencing it correctly for your import?

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

For me it worked like this

 public void onTextChanged(CharSequence s, int start,
                    int before, int count) {
                if(!s.toString().matches("^\\$(\\d{1,3}(\\,\\d{3})*|(\\d+))(\\.\\d{2})?$"))
                {
                    String userInput= ""+s.toString().replaceAll("[^\\d]", "");
                    if (userInput.length() > 2) {
                        Float in=Float.parseFloat(userInput);
                        price = Math.round(in); // just to get an Integer
                        //float percen = in/100;
                        String first, last;
                        first = userInput.substring(0, userInput.length()-2);
                        last = userInput.substring(userInput.length()-2);
                        edEx1.setText("$"+first+"."+last);
                        Log.e(MainActivity.class.toString(), "first: "+first + " last:"+last);
                        edEx1.setSelection(edEx1.getText().length());
                    }
                }
            }

Simply create a fallback to '' if the this.state.name is null.

<input name="name" type="text" value={this.state.name || ''} onChange={this.onFieldChange('name').bind(this)}/>

This also works with the useState variables.

Using modulo may introduce bias into the random numbers, depending on the random number generator. See this question for more info. Of course, it's perfectly possible to get repeating numbers in a random sequence.

Try some C++11 features for better distribution:

#include <random>
#include <iostream>

int main()
{
    std::random_device dev;
    std::mt19937 rng(dev());
    std::uniform_int_distribution<std::mt19937::result_type> dist6(1,6); // distribution in range [1, 6]

    std::cout << dist6(rng) << std::endl;
}

See this question/answer for more info on C++11 random numbers. The above isn't the only way to do this, but is one way.

I see this topic in 2 major aspects.

A) Is .NET only be reverse engineered and native not ?

B) What type of programmer we are Commercial/Hobbyist ?

Title: Protect .NET code from reverse engineering

My view:

1. Least preference to make commercial application in .NET, because it will expose even your comments on the built binary after decompile. (I don't know what is the logic to include the comments also with binary) So any one can just decompile it, rename/modify/change the look and resell the application in 24 hours.

2. In native application rename/modify/change of look is not possible as easy as one could do in .NET

3. Worried part in .NET is that you could get the whole project with solution from a single binary exe/dll.

Just imagine how week it is in security. So even a lay man could reverse engineering the .NET application easily.

4. If it is native application like C++/VB6/Delphi only expert cracker who knows ASM could patch the exe and not 100% reverse engineering like .NET.

But now the whole world is running behind the .NET because it is very easy to make projects with the advance features and libraries.

5. Good News is that Microsoft seems supporting native output from .NET in 2020 which will make coders like me to consider .NET C# as a primary language.

MySql Workbench: Strongly Recommended

This will easily handle migration problems. You can migrate selected tables of selected databases between MySql and SqlServer. You should give it a try definitely.

For complete the accepted answer, Had the same issue. First specified the remote

git remote add origin https://github.com/XXXX/YYY.git

git fetch 

Then get the code

git pull origin master

Even though there is something easy like .equals, I'd like to point out TWO mistakes you made in your code. The first: when you go through the arrays, you say b is true or false. Then you start again to check, because of the for-loop. But each time you are giving b a value. So, no matter what happens, the value b gets set to is always the value of the LAST for-loop. Next time, set boolean b = true, if equal = true, do nothing, if equal = false, b=false.

Secondly, you are now checking each value in array1 with each value in array2. If I understand correctly, you only need to check the values at the same location in the array, meaning you should have deleted the second for-loop and check like this: if (array2[i] == array1[i]). Then your code should function as well.

Your code would work like this:

public static void compareArrays(int[] array1, int[] array2) {
    boolean b = true;
    for (int i = 0; i < array2.length; i++) {
        if (array2[i] == array1[i]) {
            System.out.println("true");
        } else {
            b = false;
            System.out.println("False");
        }
    } 
    return b;

}

But as said by other, easier would be: Arrays.equals(ary1,ary2);

To ensure you obtain the right length you would need to consider unicode types as a special case. See code below.

For anyone using Koa and koa-passport:

Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:

this.session.passport.user

When you set in done(null, user) in deserializeUser where 'user' is some user object from your database:

this.req.user OR this.passport.user

for some reason this.user Koa context never gets set when you call done(null, user) in your deserializeUser method.

So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:

app.use(function * setUserInContext (next) {
  this.user = this.req.user
  yield next
})

If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher

I encountered a similar problem in my project. After struggling a lot, I found this solution:

if ($.datepicker.parseDate("dd/mm/yy","17/06/2015") > $.datepicker.parseDate("dd/mm/yy","20/06/2015"))
    // do something

You DO NOT NEED plugins like jQuery Validate or Moment.js for this issue. Hope this solution helps.

Here is a short example, the C++ way using rdbuf. I got this from the web. I can't find my original source on this:

#include <fstream>
#include <iostream>

int main () 
{
  std::ifstream f1 ("C:\\me.txt",std::fstream::binary);

  std::ofstream f2 ("C:\\me2.doc",std::fstream::trunc|std::fstream::binary);

  f2<<f1.rdbuf();

  return 0;
}

I have checked that the output redirection works with javaw:

javaw -cp ... mypath.MyClass ... arguments 1>log.txt 2>err.txt

It means, if the Java application prints out anything via System.out or System.err, it is written to those files, as also with using java (without w). Especially on starting java, the JRE may write starting errors (class not found) on the error output pipe. In this respect, it is essential to know about errors. I suggest to use the console redirection in any case if javaw is invoked.

In opposite if you use

start java .... 1>log.txt 2>err.txt

With the Windows console start command, the console output redirection does not work with java nor with javaw.

Explanation why it is so: I think that javaw opens an internal process in the OS (adequate using the java.lang.Process class), and transfers a known output redirection to this process. If no redirection is given on the command line, nothing is redirected and the internal started process for javaw doesn't have any console outputs. The behavior for java.lang.Process is similar. The virtual machine may use this internal feature for javaw too.

If you use 'start', the Windows console creates a new process for Windows to execute the command after start, but this mechanism does not use a given redirection for the started sub process, unfortunately.

In addition to @ImportanceOfBeingErnest's post, I use the following line to add a legend at an absolute position in a plot.

plt.legend(bbox_to_anchor=(1.0,1.0),\
    bbox_transform=plt.gcf().transFigure)

For unknown reasons, bbox_transform=fig.transFigure does not work with me.

It seems that your problem is more in determining the new file name rather than the rename itself (for which you could use the os.rename method).

It is not clear from your question what the pattern is that you want to be renaming. There is nothing wrong with string manipulation. A regular expression may be what you need here.

That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.

I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.

There is an odd way to do this with xcopy:

echo nnnnnnnnnnn | xcopy /-y source target

Just include as many n's as files you're copying, and it will answer n to all of the overwrite questions.

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

Before Java 5, I would kind of agree that the Map solution isn't ideal. It wouldn't give you compile time type checking so can cause issues at runtime. However, with Java 5, we have Generic Types.

So your method could look like this:

public Map<String, MyType> doStuff();

MyType of course being the type of object you are returning.

Basically I think that returning a Map is the right solution in this case because that's exactly what you want to return - a mapping of a string to an object.

In the custom fancybox I show contents with interpolated values.

in the service, in the "open" fancybox method, i do

open: function(html, $compile) {
        var el = angular.element(html);
     var compiledEl = $compile(el);
        $.fancybox.open(el); 
      }

the $compile returns compiled data. you can check the compiled data

You must detach your entity from session before modifying its ID fields

Like Jonathan suggested, using textView.setTextTypeface works, I just used it in an app a few seconds ago.

textView.setTypeface(null, Typeface.BOLD); // Typeface.NORMAL, Typeface.ITALIC etc.

To add to the other answers, note that property sheets can be configured for the project, creating custom project-specific parameters.

To access or create them navigate to(at least in Visual Studio 2013) View -> Other Windows -> Property Manager. You can also find them in the source folder as .prop files

You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:

boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))

If it is a String, you could do this:

boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))

I faced the same problem and I solved it doing the following:

Go to /home/[USER]/Android/Sdk/tools and execute:

$android list sdk -a

Which will show a list like:

1. Android SDK Tools, revision 24.0.2
2. Android SDK Platform-tools, revision 23.0.2
3. Android SDK Platform-tools, revision 23.0.1

... and many more

Then, execute the command (attention! at your computer the third option may be different):

$android update sdk -a -u -t 3

It will install the 23.0.1 SDK Platform-tools components.

Try to build your project again.

For EF 6 here's a one-liner if you're re-scaffolding a lot in development. Just update the vars and then keep using the up arrow in package manager console to rinse and repeat.

$lastGoodTarget = "OldTargetName"; $newTarget = "NewTargetName"; Update-Database -TargetMigration "$lastGoodTarget" -Verbose; Add-Migration "$newTarget" -Verbose -Force

Why is this necessary you ask? Not sure which versions of EF6 this applies but if your new migration target has already been applied then using '-Force' to re-scaffold in Add-Migration will not actually re-scaffold, but instead make a new file (this is a good thing though because you wouldn't want to lose your 'Down'). The above snippet does the 'Down' first if necessary then -Force works properly to re-scaffold.

If you use Bootstrap, try to assign margin-bottom 0 to the paragraph and after assign the property align-items-center to container, for example, like this:

<div class="row align-items-center">
     <p class="col-sm-1 mb-0">
          ....
     </p>
</div>

Bootstrap by default assign a calculate margin bottom, so mb-0 disabled this.

I hope it helps

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

The tail program can do this:

ls -lart | tail -n +2

The -n +2 means “start passing through on the second line of output”.

I suggest you to use 2 queries:

1. db.collection.count() will return total number of items. This value is stored somewhere in Mongo and it is not calculated.

2. db.collection.find().skip(20).limit(10) here I assume you could use a sort by some field, so do not forget to add an index on this field. This query will be fast too.

I think that you shouldn't query all items and than perform skip and take, cause later when you have big data you will have problems with data transferring and processing.

Use:

//REVENUE_YEAR[starts-with(.,'2552')]/../REGION/text() 

Just put a pair of double quotes around your file name like this:

this.Response.AddHeader("Content-disposition", $"attachment; filename=\"{outputFileName}\"");

Edit: This now requires C++17 and concepts. (As of 9/12/16, only g++ 6.0+ is sufficient.)

The template deduction is a lot more accurate because of it, though, so it's worth the effort of getting a newer compiler. I've not yet found a function that requires explicit template arguments.

It also now takes any appropriate callable object (and is still statically typesafe!!!).

It also now includes an optional green threading priority thread pool using the same API. This class is POSIX only, though. It uses the ucontext_t API for userspace task switching.

I created a simple library for this. An example of usage is given below. (I'm answering this because it was one of the things I found before I decided it was necessary to write it myself.)

bool is_prime(int n){
  // Determine if n is prime.
}

int main(){
  thread_pool pool(8); // 8 threads

  list<future<bool>> results;
  for(int n = 2;n < 10000;n++){
    // Submit a job to the pool.
    results.emplace_back(pool.async(is_prime, n));
  }

  int n = 2;
  for(auto i = results.begin();i != results.end();i++, n++){
    // i is an iterator pointing to a future representing the result of is_prime(n)
    cout << n << " ";
    bool prime = i->get(); // Wait for the task is_prime(n) to finish and get the result.
    if(prime)
      cout << "is prime";
    else
      cout << "is not prime";
    cout << endl;
  }  
}

You can pass async any function with any (or void) return value and any (or no) arguments and it will return a corresponding std::future. To get the result (or just wait until a task has completed) you call get() on the future.

Here's the github: https://github.com/Tyler-Hardin/thread_pool.

I came across System.Runtime.InteropServices.COMException while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM Methods. I ran Visual Studio as Administrator and the exception was gone.

You're half way there on your own. To implement a refresh, you'd just wrap what you already have in a function on the scope:

function PersonListCtrl($scope, $http) {
  $scope.loadData = function () {
     $http.get('/persons').success(function(data) {
       $scope.persons = data;
     });
  };

  //initial load
  $scope.loadData();
}

then in your markup

<div ng-controller="PersonListCtrl">
    <ul>
        <li ng-repeat="person in persons">
            Name: {{person.name}}, Age {{person.age}}
        </li>
    </ul>
   <button ng-click="loadData()">Refresh</button>
</div>

As far as "accessing your model", all you'd need to do is access that $scope.persons array in your controller:

for example (just puedo code) in your controller:

$scope.addPerson = function() {
     $scope.persons.push({ name: 'Test Monkey' });
};

Then you could use that in your view or whatever you'd want to do.

Bootstrap 3 uses the .form-control class to style form components.

<select class="form-control">
    <option value="one">One</option>
    <option value="two">Two</option>
    <option value="three">Three</option>
    <option value="four">Four</option>
    <option value="five">Five</option>
</select>

http://getbootstrap.com/css/#forms-controls

You could just do it like this

$query_select = "SELECT * FROM shouts ORDER BY id DESC LIMIT 8;"; 

$result_select = mysql_query($query_select) or die(mysql_error());

 foreach($result_select as $row){
    $ename = stripslashes($row['name']);
    $eemail = stripcslashes($row['email']);
    $epost = stripslashes($row['post']);
    $eid = $row['id'];

    $grav_url = "http://www.gravatar.com/avatar.php?gravatar_id=".md5(strtolower($eemail))."&size=70";

    echo ('<img src = "' . $grav_url . '" alt="Gravatar">'.'<br/>');

    echo $eid . '<br/>';

    echo $ename . '<br/>';

    echo $eemail . '<br/>';

    echo $epost . '<br/><br/><br/><br/>';
 }

You are creating three lists, instead of using one (you don't use the return value of DirSearch(d)). You can use a list as a parameter to save the state:

static void Main(string[] args)
{
  var list = new List<string>();
  DirSearch(list, ".");

  foreach (var file in list)
  {
    Console.WriteLine(file);
  }
}

public static void DirSearch(List<string> files, string startDirectory)
{
  try
  {
    foreach (string file in Directory.GetFiles(startDirectory, "*.*"))
    {
      string extension = Path.GetExtension(file);

      if (extension != null)
      {
        files.Add(file);
      }
    }

    foreach (string directory in Directory.GetDirectories(startDirectory))
    {
      DirSearch(files, directory);
    }
  }
  catch (System.Exception e)
  {
    Console.WriteLine(e.Message);
  }
}

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.

JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.

JComponent - A base class for objects which intend to interact with Swing.

JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).

JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.

Normally your requirements.txt file would look something like this:

package-one==1.9.4
package-two==3.7.1
package-three==1.0.1
...

To specify a Github repo, you do not need the package-name== convention.

The examples below update package-two using a GitHub repo. The text between @ and # denotes the specifics of the package.

Specify commit hash (41b95ec in the context of updated requirements.txt):

package-one==1.9.4
git+git://github.com/path/to/package-two@41b95ec#egg=package-two
package-three==1.0.1

Specify branch name (master):

git+git://github.com/path/to/package-two@master#egg=package-two

Specify tag (0.1):

git+git://github.com/path/to/[email protected]#egg=package-two

Specify release (3.7.1):

git+git://github.com/path/to/package-two@releases/tag/v3.7.1#egg=package-two

Note that #egg=package-two is not a comment here, it is to explicitly state the package name

This blog post has some more discussion on the topic.

I have had a similar problem before where it turned out to be the web brower (chrome in my case) that was the issue.

If you are using chrome, try launching it so:

For Windows:

1) Create a shortcut to Chrome on your desktop. Right-click on the shortcut and choose Properties, then switch to “Shortcut” tab.

2) In the “Target” field, append the following: –args –disable-web-security

I know I'm responding to an old post but I wanted to share an example of how to use Variable Tables when one wants to avoid using dynamic SQL. I'm not sure if its the most efficient way, however this has worked in the past for me when dynamic SQL was not an option.

Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There are 6 packet transfers before data starts transferring in FTP but only 4 in HTTP.

I think a properly tuned TCP layer would have more effect on speed than the difference between application layer protocols. The Sun Blueprint Understanding Tuning TCP has details.

Heres another good comparison of individual characteristics of each protocol.

Unknown column in WHERE clause caused by lines 1 and 2 and resolved by line 3:

1. $sql = "SELECT * FROM users WHERE username =".$userName;
2. $sql = "SELECT * FROM users WHERE username =".$userName."";
3. $sql = "SELECT * FROM users WHERE username ='".$userName."'";

To retrieve text of an auto generated span value just do this :

var al = $("#id-span-name").text();    
alert(al);

The answer marked will help you eliminate the error but it will not get MVC working. The answer to the problem is to add this line to the web.config file in system.webServer:

<modules runAllManagedModulesForAllRequests="true" />

VSCode Task - Open by App bundle identifier (macOS only).

If you don't care about any local changes (including untracked or generated files or subrepositories which just happen to be here) and just want a copy from the repo:

git reset --hard HEAD
git clean -xffd
git pull

Again, this will nuke any changes you've made locally so use carefully. Think about rm -Rf when doing this.

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

I could fix it by changing it to

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
}

in build.gradle file

I think the best way to do this is separate the 'recognition' from the functionality:

struct stringcase { char* string; void (*func)(void); };

void funcB1();
void funcAzA();

stringcase cases [] = 
{ { "B1", funcB1 }
, { "AzA", funcAzA }
};

void myswitch( char* token ) {
  for( stringcases* pCase = cases
     ; pCase != cases + sizeof( cases ) / sizeof( cases[0] )
     ; pCase++ )
  {
    if( 0 == strcmp( pCase->string, token ) ) {
       (*pCase->func)();
       break;
    }
  }

}

Many sites use AJAX/XHR/fetch to add, show, modify content dynamically and window.history API instead of in-site navigation so current URL is changed programmatically. Such sites are called SPA, short for Single Page Application.

Usual JS methods of detecting page changes

• MutationObserver (docs) to literally detect DOM changes:

  • How to change the HTML content as it's loading on the page

  • Performance of MutationObserver to detect nodes in entire DOM.

  • Simple example:

    let lastUrl = location.href; 
    new MutationObserver(() => {
      const url = location.href;
      if (url !== lastUrl) {
        lastUrl = url;
        onUrlChange();
      }
    }).observe(document, {subtree: true, childList: true});
    
    function onUrlChange() {
      console.log('URL changed!', location.href);
    }
    

• Event listener for sites that signal content change by sending a DOM event:

  • pjax:end on document used by many pjax-based sites e.g. GitHub,
    see How to run jQuery before and after a pjax load?
  • message on window used by e.g. Google search in Chrome browser,
    see Chrome extension detect Google search refresh
  • yt-navigate-finish used by Youtube,
    see How to detect page navigation on YouTube and modify its appearance seamlessly?

• Periodic checking of DOM via setInterval:
  Obviously this will work only in cases when you wait for a specific element identified by its id/selector to appear, and it won't let you universally detect new dynamically added content unless you invent some kind of fingerprinting the existing contents.

• Cloaking History API:

  let _pushState = History.prototype.pushState;
  History.prototype.pushState = function (state, title, url) {
    _pushState.call(this, state, title, url);
    console.log('URL changed', url)
  };
  

• Listening to hashchange, popstate events:

  window.addEventListener('hashchange', e => {
    console.log('URL hash changed', e);
    doSomething();
  });
  window.addEventListener('popstate', e => {
    console.log('State changed', e);
    doSomething();
  });
  

Extensions-specific methods

All above-mentioned methods can be used in a content script. Note that content scripts aren't automatically executed by the browser in case of programmatic navigation via window.history in the web page because only the URL was changed but the page itself remained the same (the content scripts run automatically only once in page lifetime).

Now let's look at the background script.

Detect URL changes in a background / event page.

There are advanced API to work with navigation: webNavigation, webRequest, but we'll use simple chrome.tabs.onUpdated event listener that sends a message to the content script:

• manifest.json:
  declare background/event page
  declare content script
  add "tabs" permission.

• background.js

  var rxLookfor = /^https?:\/\/(www\.)?google\.(com|\w\w(\.\w\w)?)\/.*?[?#&]q=/;
  chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
    if (rxLookfor.test(changeInfo.url)) {
      chrome.tabs.sendMessage(tabId, 'url-update');
    }
  });
  

• content.js

  chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
    if (msg === 'url-update') {
      // doSomething();
    }
  });
  

Error:

org.mockito.exceptions.misusing.WrongTypeOfReturnValue:
String cannot be returned by size()
size() should return int
***
If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception might occur in wrongly written multi-threaded
tests.
Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to
stub spies -
- with doReturn|Throw() family of methods. More in javadocs for
Mockito.spy() method.

Actual Code:

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Object.class, ByteString.class})

@Mock
private ByteString mockByteString;

String testData = “dsfgdshf”;
PowerMockito.when(mockByteString.toStringUtf8()).thenReturn(testData); 
// throws above given exception

Solution to fix this issue:

1st Remove annotation “@Mock”.

private ByteString mockByteString;

2nd Add PowerMockito.mock

mockByteString = PowerMockito.mock(ByteString.class);

Here's a thread safe way of doing it:

// Foo.h
@interface Foo {
}

+(NSDictionary*) dictionary;

// Foo.m
+(NSDictionary*) dictionary
{
  static NSDictionary* fooDict = nil;

  static dispatch_once_t oncePredicate;

  dispatch_once(&oncePredicate, ^{
        // create dict
    });

  return fooDict;
}

These edits ensure that fooDict is only created once.

From Apple documentation: "dispatch_once - Executes a block object once and only once for the lifetime of an application."

I think that the best way to hide the console screen of the PowerShell when your are running a background scripts is this code ("Bluecakes" answer).

I add this code in the beginning of all my PowerShell scripts that I need to run in background.

# .Net methods for hiding/showing the console in the background
Add-Type -Name Window -Namespace Console -MemberDefinition '
[DllImport("Kernel32.dll")]
public static extern IntPtr GetConsoleWindow();

[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);
'
function Hide-Console
{
    $consolePtr = [Console.Window]::GetConsoleWindow()
    #0 hide
    [Console.Window]::ShowWindow($consolePtr, 0)
}
Hide-Console

If this answer was help you, please vote to "Bluecakes" in his answer in this post.

I believe it happens when the actual request is not sent. Usually happens when you are loading a cached resource.

#sorting first by age then profession,you can change it in function "fun".
a = []

def fun(v):
    return (v[1],v[2])

# create the table (name, age, job)
a.append(["Nick", 30, "Doctor"])
a.append(["John",  8, "Student"])
a.append(["Paul",  8,"Car Dealer"])
a.append(["Mark", 66, "Retired"])

a.sort(key=fun)


print a

From the grep(1) man page:

  -l, --files-with-matches
          Suppress  normal  output;  instead  print the name of each input
          file from which output would normally have  been  printed.   The
          scanning  will  stop  on  the  first match.  (-l is specified by
          POSIX.)

-Filter only accepts a single string. -Include accepts multiple values, but qualifies the -Path argument. The trick is to append \* to the end of the path, and then use -Include to select multiple extensions. BTW, quoting strings is unnecessary in cmdlet arguments unless they contain spaces or shell special characters.

Get-ChildItem $originalPath\* -Include *.gif, *.jpg, *.xls*, *.doc*, *.pdf*, *.wav*, .ppt*

Note that this will work regardless of whether $originalPath ends in a backslash, because multiple consecutive backslashes are interpreted as a single path separator. For example, try:

Get-ChildItem C:\\\\\Windows

DECLARE @Daysforward int
SELECT @Daysforward = 25 (no of days required)
Select * from table name

where CAST( columnDate AS date) < DATEADD(day,1+@Daysforward,CAST(GETDATE() AS date))

Not sure if it will fix your particular issue but worth sharing anyway.

I had issues with twitter boot strap in IE. No rounded corners. Navigation menu not collapsing. Spans not sitting in correct location, even some images not displaying.

Strangely, site works okay in IE when run through visual studio debugger, its once deployed to a server that the problem occurs.

Try using IE developer tools (F12 is keyboard shortcut) Check your browser mode and document mode. (its at the top along side the menu bar)

Problem happened for me as document was IE7 and browser was IE10 compatibility. I added a http header in IIS: Name X-UA-Compatible Value IE=EmulateIE9

Now the page loads as document - IE9 standards, browser IE10 compatibility and all the previous issues are resolved.

Hope this helps.

This answer has a problem:

style="text-transform: uppercase"

it also converts the place holder word to upper case which is inconvenient

placeholder="first name"

when rendering the input, it writes "first name" placeholder as uppercase

FIRST NAME

so i wrote something better:

onkeypress="this.value = this.value + event.key.toUpperCase(); return false;"

it works good!, but it has some side effects if your javascript code is complex,

hope it helps somebody to give him/her an idea to develop a better solution.

For me, the only thing which worked is

git diff HEAD

including the staged files, git diff --cached only shows staged files.

Check sleep(3) man page or MSDN for Sleep

I faced the same issue while submitting the app using Xcode 4.6. It does not recognise the icons with dimension 120x120, 58x58, 29x29, etc. So when I tried to add these icons into the info.plist and submit the app for review, Xcode 4.6 did not allow me to do so. On submitting the app without the above icons, I got a mail saying -

"Your delivery was successful, but you may wish to correct the following issues in your next delivery: Missing recommended icon file - The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format."

Since, it was recommended and not necessary, I submitted the app anyhow. I added the above recommended icons to the bundle but did not specify them in the Info.plist. I got the same mail again. This time I ignored it and to my surprise the app was accepted.

I wanted my app to run on iOS 5 and above and therefore, I had to use Xcode 4.6 and not the latest Xcode 5 which properly allows only apps for iOS7 and above only.

UPDATE:

NOTE: "Starting February 1st 2014 new apps and app updates submitted to the App Store must be built with Xcode 5 and iOS 7 SDK". https://developer.apple.com/news/?id=12172013a#top

Thus, this scenario will be invalid in future.

Just keep a currentValue variable in your controller that you update on every change. You can then compare that to the new value every time before you update it.'

The idea of using a watch is good as well, but I think a simple variable is the simplest and most logical solution.

You can use ax.figure.savefig(), as suggested in a comment on the question:

import pandas as pd

df = pd.DataFrame([0, 1])
ax = df.plot.line()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in other answers, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

and dont forget to clean your project after writing these lines you`ll a get an error in your xml file until you´ve cleaned your project in eclipse: Project->Clean...

Following on from chimeric's answer above:

To get ALL the column indices in the df, so i used:

which(!names(df)%in%c()) 

or store in a list:

indexLst<-which(!names(df)%in%c())

You can actualy fake the transparency of option DOMElements with the following CSS:

CSS

option { 
    /* Whatever color  you want */
    background-color: #82caff;
}

See Demo

The option tag does not support rgba colors yet.

Use sed's substitution: sed 's/"//g'

s/X/Y/ replaces X with Y.

g means all occurrences should be replaced, not just the first one.

I ran the following command ALTER USER 'root' @ 'localhost' identified with mysql_native_password BY 'root123'; in the command line and finally restart MySQL in local services.

public static List<List<float[]>> SplitList(List<float[]> locations, int nSize=30)  
{        
    var list = new List<List<float[]>>(); 

    for (int i = 0; i < locations.Count; i += nSize) 
    { 
        list.Add(locations.GetRange(i, Math.Min(nSize, locations.Count - i))); 
    } 

    return list; 
} 

Generic version:

public static IEnumerable<List<T>> SplitList<T>(List<T> locations, int nSize=30)  
{        
    for (int i = 0; i < locations.Count; i += nSize) 
    { 
        yield return locations.GetRange(i, Math.Min(nSize, locations.Count - i)); 
    }  
} 

Which server are you using?

Like already said:

1. In your debug configuration you'll have to define the right port of your server (GF:9009 / Tomcat:8000)
2. You'll have to set the JVM property of the server to debug

For Glassfish:

    Log in to admin-console > Configurations > server-config > JVM-Settings > check DEBUG checkbox > restart server

For Tomcat:

create file debug.bat/.sh (depending on your OS) in %TOMCAT_HOME%/bin directory and write

    set JPDA_ADDRESS=8000
    set JPDA_TRANSPORT=dt_socket
    catalina.bat jpda start

in it.

After you've created this file start server by executing debug.bat/.sh.

Now you should be able to debug remotely in Eclipse after you set the necessary properties in your debug configuration.

Hope this helped! Have Fun!

EDIT

If you're running tomcat in a Win environment as a service you don't have a catalina.bat file in the bin-directory of your tomcat installation.
To set your server into debug-mode please try the following:

1. Run the Configuration option in Windows Menu or run %catalina_home%/bin/tomcat6w.exe
2. In Java tab, add this line to Java:

options:-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

I came across the same problem. You might get this error in many situations like below.

• Some dependency problem in your pom.xml
• The run configuration may not have proper configuration. You might want to delete the existing one and create the new one like suggested in other answers.
• You may want to try like mvn clean, mvn build and other options.
• You may want to delete the project and import it again.
• You may want to restart Eclipse and check your luck if it works.

Here, the list of hit and trial goes on. Believe me the tool Eclipse is not that stupid. It is quite smart to find errors even at compile time. I tried all ways mentioned above, but none worked for me.

The main problem which worked for me was JRE version which was somehow got set to default (JRE System Library [jre1.5]). I reset it to jre1.8.* which I had installed in my machine.

I don't commit that this is only the solution to this problem but yes this could be one of the solution. So keep an eye on JRE version.

Check this:

// Define the border style of the form to a dialog box.
form1.FormBorderStyle = FormBorderStyle.FixedDialog;

// Set the MaximizeBox to false to remove the maximize box.
form1.MaximizeBox = false;

// Set the MinimizeBox to false to remove the minimize box.
form1.MinimizeBox = false;

// Set the start position of the form to the center of the screen.
form1.StartPosition = FormStartPosition.CenterScreen;

// Display the form as a modal dialog box.
form1.ShowDialog();

singletonList can hold instance of any object. Object state can be modify.

List<Character> list = new ArrayList<Character>();
list.add('X');
list.add('Y');
System.out.println("Initial list: "+ list);
List<List<Character>> list2 = Collections.singletonList(list);
list.add('Z');
System.out.println(list);
System.out.println(list2);

We can not define unmodifiableList like above.

If you are trying to build John the Ripper "bleeding-jumbo" and get an error like "make: *** No rule to make target 'linux-x86-64'". Try running this command instead: ./configure && make

Presumably you could kick off a setTimeout call in mousedown, and then cancel it in mouseup (if mouseup happens before your timeout completes).

However, looks like there is a plugin: longclick.

In my case

spring.profiles = production // remove it to fix

in application.properties was the reason

In Java, when you type a decimal number as 3.6, its interpreted as a double. double is a 64-bit precision IEEE 754 floating point, while floatis a 32-bit precision IEEE 754 floating point. As a float is less precise than a double, the conversion cannot be performed implicitly.

If you want to create a float, you should end your number with f (i.e.: 3.6f).

For more explanation, see the primitive data types definition of the Java tutorial.

rake db:migrate:down VERSION=your_migrations's_version_number_here

The version is the numerical prefix on the migration's file name

How to find version:

Your migration files are stored in your rails_root/db/migrate directory. Find appropriate file up to which you want to rollback and copy the prefix number.

for example

file name: 20140208031131_create_roles.rb then the version is 20140208031131

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

Good question.

• @@IDENTITY: returns the last identity value generated on your SQL connection (SPID). Most of the time it will be what you want, but sometimes it isn't (like when a trigger is fired in response to an INSERT, and the trigger executes another INSERT statement).

• SCOPE_IDENTITY(): returns the last identity value generated in the current scope (i.e. stored procedure, trigger, function, etc).

• IDENT_CURRENT(): returns the last identity value for a specific table. Don't use this to get the identity value from an INSERT, it's subject to race conditions (i.e. multiple connections inserting rows on the same table).

• IDENTITY(): used when declaring a column in a table as an identity column.

For more reference, see: http://msdn.microsoft.com/en-us/library/ms187342.aspx.

To summarize: if you are inserting rows, and you want to know the value of the identity column for the row you just inserted, always use SCOPE_IDENTITY().

You should join T1 and T2 tables using sql joins in order to analyze from two tables. Link for learn joins : https://www.w3schools.com/sql/sql_join.asp

Best is to just Apply margin-top: 2px on the input element.

Bootstrap adds a margin-top: 4px to input element causing radio button to move down than the content.

Have you tried this?

ALTER TABLE <table_name> MODIFY <col_name> VARCHAR(65353);

This will change the col_name's type to VARCHAR(65353)

The PowerShell answers are good, but the Rename-Item command doesn't work in the same target directory unless ALL of your files have the unwanted character in them (fails if it finds duplicates).

If you're like me and had a mix of good names and bad names, try this script instead (will replace spaces with an underscore):

Get-ChildItem -recurse -name | ForEach-Object { Move-Item $_ $_.replace(" ", "_") }

I am contributing here, as the OP asked:

How to change collation of database, table, column?

The selected answer just states it on table level.

Changing it database wide:

ALTER DATABASE <database_name> CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Changing it per table:

ALTER TABLE <table_name> CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Good practice is to change it at table level as it'll change it for columns as well. Changing for specific column is for any specific case.

Changing collation for a specific column:

ALTER TABLE <table_name> MODIFY <column_name> VARCHAR(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

This is what you should do. It should work in that you have a 1 second animation, then a 4 second delay between iterations:

@keyframes barshine {
  0% {
  background-image:linear-gradient(120deg,rgba(255,255,255,0) 0%,rgba(255,255,255,0.25) -5%,rgba(255,255,255,0) 0%);
  }
  20% {
    background-image:linear-gradient(120deg,rgba(255,255,255,0) 10%,rgba(255,255,255,0.25) 105%,rgba(255,255,255,0) 110%);
  }
}
.progbar {
  animation: barshine 5s 0s linear infinite;
}

So I've been messing around with this a lot and you can do it without being very hacky. This is the simplest way to put in a delay between animation iterations that's 1. SUPER EASY and 2. just takes a little logic. Check out this dance animation I've made:

.dance{
  animation-name: dance;
  -webkit-animation-name: dance;

  animation-iteration-count: infinite;
  -webkit-animation-iteration-count: infinite;
  animation-duration: 2.5s;
  -webkit-animation-duration: 2.5s;

  -webkit-animation-delay: 2.5s;
  animation-delay: 2.5s;
  animation-timing-function: ease-in;
  -webkit-animation-timing-function: ease-in;

}
@keyframes dance {

    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    transform: rotate(0deg);
  }

    -webkit-transform: rotate(-120deg);
    -moz-transform: rotate(-120deg);

  }

  }
  60% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  80% {
    -webkit-transform: rotate(-120deg);
    -moz-transform: rotate(-120deg);
    -o-transform: rotate(-120deg);
    -ms-transform: rotate(-120deg);
    transform: rotate(-120deg);
  }
  95% {
    -webkit-transform: rotate(20deg);
    -moz-transform: rotate(20deg);
    -o-transform: rotate(20deg);
    -ms-transform: rotate(20deg);
    transform: rotate(20deg);
  }
}

I actually came here trying to figure out how to put a delay in the animation, when I realized that you just 1. extend the duration of the animation and shirt the proportion of time for each animation. Beore I had them each lasting .5 seconds for the total duration of 2.5 seconds. Now lets say i wanted to add a delay equal to the total duration, so a 2.5 second delay.

You animation time is 2.5 seconds and delay is 2.5, so you change duration to 5 seconds. However, because you doubled the total duration, you'll want to halve the animations proportion. Check the final below. This worked perfectly for me.

@-webkit-keyframes dance {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  10% {
    -webkit-transform: rotate(20deg);
    -moz-transform: rotate(20deg);
    -o-transform: rotate(20deg);
    -ms-transform: rotate(20deg);
    transform: rotate(20deg);
  }
  20% {
    -webkit-transform: rotate(-120deg);
    -moz-transform: rotate(-120deg);
    -o-transform: rotate(-120deg);
    -ms-transform: rotate(-120deg);
    transform: rotate(-120deg);
  }
  30% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  40% {
    -webkit-transform: rotate(-120deg);
    -moz-transform: rotate(-120deg);
    -o-transform: rotate(-120deg);
    -ms-transform: rotate(-120deg);
    transform: rotate(-120deg);
  }
  50% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    transform: rotate(0deg);
  }
}

In sum:

These are the calcultions you'd probably use to figure out how to change you animation's duration and the % of each part.

desired_duration = x

desired_duration = animation_part_duration1 + animation_part_duration2 + ... (and so on)

desired_delay = y

total duration = x + y

animation_part_duration1_actual = animation_part_duration1 * desired_duration / total_duration

If you got nothing when inputted fastboot devices, it meaned you devices fail to enter fastboot model. Make sure that you enter fastboot model via press these three button simultaneously, power key, volume key(both '+' and '-'). Then you can see you devices via fastboot devices and continue to flash your devices.

note:I entered fastboot model only pressed 'power key' and '-' key before, and present the same problem.

shortest Bootstrap-compatible way, no JavaScript:

.cameraicon {
height: 1.6em;/* set your own icon size */
mask: url(/camera.svg); /* path to your image */
-webkit-mask: url(/camera.svg) no-repeat center;
}

and use it like:

<td class="text-center">
    <div class="bg-secondary cameraicon"/><!-- "bg-secondary" sets actual color of your icon -->
</td>

I would put this as a comment, but I don't have the rep for it. What Josh Crozier answered is correct, but for IE .cur and .ani are the only supported formats for this. So you should probably have a fallback just in case:

.test {
    cursor:url("http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif"), url(foo.cur), auto;
}

I use Privoxy and cURL to scrape Tor pages:

<?php
    $ch = curl_init('http://jhiwjjlqpyawmpjx.onion'); // Tormail URL
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
    curl_setopt($ch, CURLOPT_PROXY, "localhost:8118"); // Default privoxy port
    curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
    curl_exec($ch);
    curl_close($ch);
?>

After installing Privoxy you need to add this line to the configuration file (/etc/privoxy/config). Note the space and '.' a the end of line.

forward-socks4a / localhost:9050 .

Then restart Privoxy.

/etc/init.d/privoxy restart

Solution with timeout, prevent memory leak :

The following code is based on Brandon Tilley's answer :

var http = require('http'),
    fs = require('fs');

var request = http.get("http://example12345.com/yourfile.html", function(response) {
    if (response.statusCode === 200) {
        var file = fs.createWriteStream("copy.html");
        response.pipe(file);
    }
    // Add timeout.
    request.setTimeout(12000, function () {
        request.abort();
    });
});

Don't make file when you get an error, and prefere to use timeout to close your request after X secondes.

You can also use echo to remove blank spaces, either at the beginning or at the end of the string, but also repeating spaces inside the string.

$ myVar="    kokor    iiij     ook      "
$ echo "$myVar"
    kokor    iiij     ook      
$ myVar=`echo $myVar`
$
$ # myVar is not set to "kokor iiij ook"
$ echo "$myVar"
kokor iiij ook

I use the code I found @.w3resources

The code takes care of

• month being less than 12,

• days being less than 32

• even works with leap years. While Using in my project for leap year I modify the code like

  if ((lyear==false) && (dd>=29))
  {
  alert('Invalid date format!');
  return false;
  }

  if ((lyear==false) && (dd>=29))
  {
  alert('not a Leap year February cannot have more than 28days');
  return false;
  }

Rather than throwing the generic "Invalid date format" error which does not make much sense to the user. I modify the rest of the code to provide valid error message like month cannot be more than 12, days cannot be more than 31 etc.,

The problem with using Regular expression is it is difficult to identify exactly what went wrong. It either gives a True or a false-Without any reason why it failed. We have to write multiple regular expressions to sort this problem.

I figured that the DJANGO_SETTINGS_MODULE had to be set some way, so I looked at the documentation (link updated) and found:

export DJANGO_SETTINGS_MODULE=mysite.settings

Though that is not enough if you are running a server on heroku, you need to specify it there, too. Like this:

heroku config:set DJANGO_SETTINGS_MODULE=mysite.settings --account <your account name> 

In my specific case I ran these two and everything worked out:

export DJANGO_SETTINGS_MODULE=nirla.settings
heroku config:set DJANGO_SETTINGS_MODULE=nirla.settings --account personal

Edit

I would also like to point out that you have to re-do this every time you close or restart your virtual environment. Instead, you should automate the process by going to venv/bin/activate and adding the line: set DJANGO_SETTINGS_MODULE=mysite.settings to the bottom of the code. From now on every time you activate the virtual environment, you will be using that app's settings.

Regionally independent date time parsing

The output format of %DATE% and of the dir command is regionally dependent and thus neither robust nor smart. date.exe (part of UnxUtils) delivers any date and time information in any thinkable format. You may also extract the date/time information from any file with date.exe.

Examples: (in a cmd-script use %% instead of %)

date.exe +"%Y-%m-%d"
2009-12-22

date.exe +"%T"
18:55:03

date.exe +"%Y%m%d %H%M%S: Any text"
20091222 185503: Any text

date.exe +"Text: %y/%m/%d-any text-%H.%M"
Text: 09/12/22-any text-18.55

Command: date.exe +"%m-%d """%H %M %S """"
07-22 "18:55:03"`

The date/time information from a reference file:
date.exe -r c:\file.txt +"The timestamp of file.txt is: %Y-%m-%d %H:%M:%S"

Using it in a CMD script to get year, month, day, time information:

for /f "tokens=1,2,3,4,5,6* delims=," %%i in ('C:\Tools\etc\date.exe +"%%y,%%m,%%d,%%H,%%M,%%S"') do set yy=%%i& set mo=%%j& set dd=%%k& set hh=%%l& set mm=%%m& set ss=%%n

Using it in a CMD script to get a timestamp in any required format:

for /f "tokens=*" %%i in ('C:\Tools\etc\date.exe +"%%y-%%m-%%d %%H:%%M:%%S"') do set timestamp=%%i

Extracting the date/time information from any reference file.

for /f "tokens=1,2,3,4,5,6* delims=," %%i in ('C:\Tools\etc\date.exe -r file.txt +"%%y,%%m,%%d,%%H,%%M,%%S"') do set yy=%%i& set mo=%%j& set dd=%%k& set hh=%%l& set mm=%%m& set ss=%%n

Adding to a file its date/time information:

for /f "tokens=*" %%i in ('C:\Tools\etc\date.exe -r file.txt +"%%y-%%m-%%d.%%H%%M%%S"') do ren file.txt file.%%i.txt

date.exe is part of the free GNU tools which need no installation.

NOTE: Copying date.exe into any directory which is in the search path may cause other scripts to fail that use the Windows built-in date command.

<div style="width:100px;height:100px;overflow-x:hidden;overflow-y:auto;background-color:#000000">

If the culture of the result doesn't matters or we're only talking of integer values, CONVERT or CAST will be fine.

However, if the result must match a specific culture, FORMAT might be the function to go:

DECLARE @value DECIMAL(19,4) = 1505.5698
SELECT CONVERT(NVARCHAR, @value)        -->  1505.5698
SELECT FORMAT(@value, 'N2', 'en-us')    --> 1,505.57
SELECT FORMAT(@value, 'N2', 'de-de')    --> 1.505,57

For more information on FORMAT see here.

Of course, formatting the result should be a matter of the UI layer of the software.

I recommend against using the jQuery code that was accepted as the answer. While it does not insert the string to decode into the page, it does cause things such as scripts and HTML elements to get created. This is way more code than we need. Instead, I suggest using a safer, more optimized function.

var decodeEntities = (function() {
  // this prevents any overhead from creating the object each time
  var element = document.createElement('div');

  function decodeHTMLEntities (str) {
    if(str && typeof str === 'string') {
      // strip script/html tags
      str = str.replace(/<script[^>]*>([\S\s]*?)<\/script>/gmi, '');
      str = str.replace(/<\/?\w(?:[^"'>]|"[^"]*"|'[^']*')*>/gmi, '');
      element.innerHTML = str;
      str = element.textContent;
      element.textContent = '';
    }

    return str;
  }

  return decodeHTMLEntities;
})();

http://jsfiddle.net/LYteC/4/

To use this function, just call decodeEntities("&") and it will use the same underlying techniques as the jQuery version will—but without jQuery's overhead, and after sanitizing the HTML tags in the input. See Mike Samuel's comment on the accepted answer for how to filter out HTML tags.

This function can be easily used as a jQuery plugin by adding the following line in your project.

jQuery.decodeEntities = decodeEntities;

Unlike C, Java allows using the % for both integer and floating point and (unlike C89 and C++) it is well-defined for all inputs (including negatives):

From JLS §15.17.3:

The result of a floating-point remainder operation is determined by the rules of IEEE arithmetic:

• If either operand is NaN, the result is NaN.
• If the result is not NaN, the sign of the result equals the sign of the dividend.
• If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.
• If the dividend is finite and the divisor is an infinity, the result equals the dividend.
• If the dividend is a zero and the divisor is finite, the result equals the dividend.
• In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r from the division of a dividend n by a divisor d is defined by the mathematical relation r=n-(d·q) where q is an integer that is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as possible without exceeding the magnitude of the true mathematical quotient of n and d.

So for your example, 0.5/0.3 = 1.6... . q has the same sign (positive) as 0.5 (the dividend), and the magnitude is 1 (integer with largest magnitude not exceeding magnitude of 1.6...), and r = 0.5 - (0.3 * 1) = 0.2

I got this problem too and I fixed it in this way. I was trying to run mapreduce job locally through Eclipse, after set the configurations, I met this error (in Linux, Virtual Box) To solve it,

• right click on the project you want to run,
• go "Properties"->"Java Build Path"->"Add External Jars",
• then go to file:/usr/lib/Hadoop/client-0.20, choose the three jars named started by "slf4j".

Then you'll be able to run the job locally. Hope my experience will help someone.

The Groovy way to do this is

def list = []
list << new MyType(...)

which creates a list and uses the overloaded leftShift operator to append an item

See the Groovy docs on Lists for lots of examples.

You can calculate A mod B (for positive numbers) using this:

Pol( -Rec( ¹/_2π^r , 2π^r × ^A/_B ) , Y ) ( π^r - Y ) B

Then press [CALC], and enter your values for A and B, and any value for Y.

/ indicates using the fraction key, and ^r means radians ( [SHIFT] [Ans] [2] )

You can use robocopy to copy files with an archive flag and reset the attribute. Use /M command line, this is my backup script with few extra tricks.

This script needs NirCmd tool to keep mouse moving so that my machine won't fall into sleep. Script is using a lockfile to tell when backup script is completed and mousemove.bat script is closed. You may leave this part out.

Another is 7-Zip tool for splitting virtualbox files smaller than 4GB files, my destination folder is still FAT32 so this is mandatory. I should use NTFS disk but haven't converted backup disks yet.

Just have your view controller register for the UIApplicationWillEnterForegroundNotification notification and react accordingly.

Status 301 means that the resource (page) is moved permanently to a new location. The client/browser should not attempt to request the original location but use the new location from now on.

Status 302 means that the resource is temporarily located somewhere else, and the client/browser should continue requesting the original url.

You dont need absolute positioning Use

p {
 text-align: center;
line-height: 100px;

}

And adjust at will...

If text exceeds width and goes more than one line

In that case the adjust you can do is to include the display property in your rules as follows;

(I added a background for a better view of the example)

div
{
  width:300px;
  height:100px;  
  display: table; 
  background:#ccddcc;  
}


p {
  text-align:center; 
  vertical-align: middle;
  display: table-cell;   
}

Play with it in this JBin

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

(Source)

1. Create a new Windows Application with the wizard.
2. Delete Form1 from the code.
3. Remove the code in Program.cs starting up the Form1.
4. Use the NotifyIcon class to create your system tray icon (assign an icon to it).
5. Add a contextmenu to it.
6. Or react to NotifyIcon's mouseclick and differenciate between Right and Left click, setting your contextmenu and showing it for which ever button (right/left) was pressed.
7. Application.Run() to keep the app running with Application.Exit() to quit. Or a bool bRunning = true; while(bRunning){Application.DoEvents(); Thread.Sleep(10);}. Then set bRunning = false; to exit the app.

I have wrote this simple function for myself:

function sortObj(list, key) {
    function compare(a, b) {
        a = a[key];
        b = b[key];
        var type = (typeof(a) === 'string' ||
                    typeof(b) === 'string') ? 'string' : 'number';
        var result;
        if (type === 'string') result = a.localeCompare(b);
        else result = a - b;
        return result;
    }
    return list.sort(compare);
}

for example you have list of cars:

var cars= [{brand: 'audi', speed: 240}, {brand: 'fiat', speed: 190}];
var carsSortedByBrand = sortObj(cars, 'brand');
var carsSortedBySpeed = sortObj(cars, 'speed');

Window-->Web Browser--> Firefox

To do it exactly your way? You could use the for...else structure

for url in list_of_urls:
    for url_dict in urls:
        if url_dict['url'] == url:
            url_dict['nbr'] += 1
            break
    else:
        urls.append(dict(url=url, nbr=1))

But it is quite inelegant. Do you really have to store the visited urls as a LIST? If you sort it as a dict, indexed by url string, for example, it would be way cleaner:

urls = {'http://www.google.fr/': dict(url='http://www.google.fr/', nbr=1)}

for url in list_of_urls:
    if url in urls:
        urls[url]['nbr'] += 1
    else:
        urls[url] = dict(url=url, nbr=1)

A few things to note in that second example:

• see how using a dict for urls removes the need for going through the whole urls list when testing for one single url. This approach will be faster.
• Using dict( ) instead of braces makes your code shorter
• using list_of_urls, urls and url as variable names make the code quite hard to parse. It's better to find something clearer, such as urls_to_visit, urls_already_visited and current_url. I know, it's longer. But it's clearer.

And of course I'm assuming that dict(url='http://www.google.fr', nbr=1) is a simplification of your own data structure, because otherwise, urls could simply be:

urls = {'http://www.google.fr':1}

for url in list_of_urls:
    if url in urls:
        urls[url] += 1
    else:
        urls[url] = 1

Which can get very elegant with the defaultdict stance:

urls = collections.defaultdict(int)
for url in list_of_urls:
    urls[url] += 1

Try this:

in.nextLine();

This advances the Scanner to the next line.

this reference a javascript object and $(this) used to encapsulate with jQuery.

Example =>

// Getting Name and modify css property of dom object through jQuery
var name = $(this).attr('name');
$(this).css('background-color','white')

// Getting form object and its data and work on..
this = document.getElementsByName("new_photo")[0]
formData = new FormData(this)

// Calling blur method on find input field with help of both as below
$(this).find('input[type=text]')[0].blur()

//Above is equivalent to
this = $(this).find('input[type=text]')[0]
this.blur()

//Find value of a text field with id "index-number"
this = document.getElementById("index-number");
this.value

or 

this = $('#index-number');
$(this).val(); // Equivalent to $('#index-number').val()
$(this).css('color','#000000')
