You can do this with css too.

just use position:fixed; for what you want to be fixed when you scroll down.

you can have some examples here:

I think this may help u,

+(BOOL)isKeyBoardInDisplay  {

    BOOL isExists = NO;
    for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows])   {
        if ([[keyboardWindow description] hasPrefix:@"<UITextEffectsWindow"] == YES) {
            isExists = YES;
        }  
    }

    return isExists;
}

We've been using the below class -

class SleepSimulator{
     QMutex localMutex;
     QWaitCondition sleepSimulator;
public:
    SleepSimulator::SleepSimulator()
    {
        localMutex.lock();
    }
    void sleep(unsigned long sleepMS)
    {
        sleepSimulator.wait(&localMutex, sleepMS);
    }
    void CancelSleep()
    {
        sleepSimulator.wakeAll();
    }
};

QWaitCondition is designed to coordinate mutex waiting between different threads. But what makes this work is the wait method has a timeout on it. When called this way, it functions exactly like a sleep function, but it uses Qt's event loop for the timing. So, no other events or the UI are blocked like normal windows sleep function does.

As a bonus, we added the CancelSleep function to allows another part of the program to cancel the "sleep" function.

What we liked about this is that it lightweight, reusable and is completely self contained.

QMutex: http://doc.qt.io/archives/4.6/qmutex.html

QWaitCondition: http://doc.qt.io/archives/4.6/qwaitcondition.html

If you only need different expressions for different cases then this may work for you:

expr1 if condition1 else expr2 if condition2 else expr

For example:

a = "neg" if b<0 else "pos" if b>0 else "zero"

I was changing this entry (for which my web server was not running and showing me access denied error for a particular port)

<bindings>
   <binding protocol="http" bindingInformation="*:61235:localhost" />
</bindings>

in the "applicationhost.config" in "Documents\IISExpress\config" for a particular webapplication it was overwritten by Visual Studio 2012 again to default port whenever I was starting my webapplication.

But I resolved the problem by doing nothing in the applicationhost.config. I just changed the "project properties" > "web" > "project url" setting from http://localhost:62135/ to http://localhost:47279/(depends on your computer) and it worked for me.

RUN git clone http://username:password@url/example.git
WORKDIR /folder
RUN make

There are multiple ways to achieve this. I can explain you in brief about the 4 types which we use in our daily programming life cycle.

Please go through the below points.

1 Query String.

FirstForm.aspx.cs

Response.Redirect("SecondForm.aspx?Parameter=" + TextBox1.Text);

SecondForm.aspx.cs

TextBox1.Text = Request.QueryString["Parameter"].ToString();

This is the most reliable way when you are passing integer kind of value or other short parameters. More advance in this method if you are using any special characters in the value while passing it through query string, you must encode the value before passing it to next page. So our code snippet of will be something like this:

FirstForm.aspx.cs

Response.Redirect("SecondForm.aspx?Parameter=" + Server.UrlEncode(TextBox1.Text));

SecondForm.aspx.cs

TextBox1.Text = Server.UrlDecode(Request.QueryString["Parameter"].ToString());

URL Encoding

1. Server.URLEncode
   
2. HttpServerUtility.UrlDecode

2. Passing value through context object

Passing value through context object is another widely used method.

FirstForm.aspx.cs

TextBox1.Text = this.Context.Items["Parameter"].ToString();

SecondForm.aspx.cs

this.Context.Items["Parameter"] = TextBox1.Text;
Server.Transfer("SecondForm.aspx", true);

Note that we are navigating to another page using Server.Transfer instead of Response.Redirect.Some of us also use Session object to pass values. In that method, value is store in Session object and then later pulled out from Session object in Second page.

3. Posting form to another page instead of PostBack

Third method of passing value by posting page to another form. Here is the example of that:

FirstForm.aspx.cs

private void Page_Load(object sender, System.EventArgs e)
{
   buttonSubmit.Attributes.Add("onclick", "return PostPage();");
}

And we create a javascript function to post the form.

SecondForm.aspx.cs

function PostPage()
{
   document.Form1.action = "SecondForm.aspx";
   document.Form1.method = "POST";
   document.Form1.submit();
}
TextBox1.Text = Request.Form["TextBox1"].ToString();

Here we are posting the form to another page instead of itself. You might get viewstate invalid or error in second page using this method. To handle this error is to put EnableViewStateMac=false

4. Another method is by adding PostBackURL property of control for cross page post back

In ASP.NET 2.0, Microsoft has solved this problem by adding PostBackURL property of control for cross page post back. Implementation is a matter of setting one property of control and you are done.

FirstForm.aspx.cs

<asp:Button id=buttonPassValue style=”Z-INDEX: 102" runat=”server” Text=”Button”         PostBackUrl=”~/SecondForm.aspx”></asp:Button>

SecondForm.aspx.cs

TextBox1.Text = Request.Form["TextBox1"].ToString();

In above example, we are assigning PostBackUrl property of the button we can determine the page to which it will post instead of itself. In next page, we can access all controls of the previous page using Request object.

You can also use PreviousPage class to access controls of previous page instead of using classic Request object.

SecondForm.aspx

TextBox textBoxTemp = (TextBox) PreviousPage.FindControl(“TextBox1");
TextBox1.Text = textBoxTemp.Text;

As you have noticed, this is also a simple and clean implementation of passing value between pages.

HAPPY CODING!

You could build your form using FormBuilder as it let you more flexible way to configure form.

export class MyComp {
  form: ControlGroup;

  constructor(@Inject()fb: FormBuilder) {  
    this.form = fb.group({  
      foo: ['', MyValidators.regex(/^(?!\s|.*\s$).*$/)]  
    });  
  }

Then in your template :

<input type="text" ngControl="foo" />
<div *ngIf="!form.foo.valid">Please correct foo entry !</div> 

You can also customize ng-invalid CSS class.

As there is actually no validators for regex, you have to write your own. It is a simple function that takes a control in input, and return null if valid or a StringMap if invalid.

export class MyValidators {
  static regex(pattern: string): Function {
    return (control: Control): {[key: string]: any} => {
      return control.value.match(pattern) ? null : {pattern: true};
    };
  }
}

Hope that it help you.

"-P" is the right option, please read on for more related information:

wget -nd -np -P /dest/dir --recursive http://url/dir1/dir2

Relevant snippets from man pages for convenience:

   -P prefix
   --directory-prefix=prefix
       Set directory prefix to prefix.  The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree.  The default is . (the current directory).

   -nd
   --no-directories
       Do not create a hierarchy of directories when retrieving recursively.  With this option turned on, all files will get saved to the current directory, without clobbering (if a name shows up more than once, the
       filenames will get extensions .n).


   -np
   --no-parent
       Do not ever ascend to the parent directory when retrieving recursively.  This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded.

These are the prerequisites of directly using the script name:

1. Add the shebang line (#!/bin/bash) at the very top.
2. Use chmod u+x scriptname to make the script executable (where scriptname is the name of your script).
3. Place the script under /usr/local/bin folder.
   • Note: I suggest placing it under /usr/local/bin because most likely that path will be already added to your PATH variable.
4. Run the script using just its name, scriptname.

If you don't have access to /usr/local/bin then do the following:

1. Create a folder in your home directory and call it bin.

2. Do ls -lA on your home directory, to identify the start-up script your shell is using. It should be either .profile or .bashrc.

3. Once you have identified the start up script, add the following line:

   PATH="$PATH:$HOME/bin"
   

4. Once added, source your start-up script or log out and log back in.

   To source, put . followed by a space and then your start-up script name, e.g. . .profile or . .bashrc

5. Run the script using just its name, scriptname.

string1.equals(string2) is right way to do it.

String s = "something", t = "maybe something else";
 if (s == t)      // Legal, but usually results WRONG.
 if (s.equals(t)) // RIGHT way to check the two strings
  /* == will fail in following case:*/
 String s1 = new String("abc");
 String s2 = new String("abc");

 if(s1==s2) //it will return false

I was trying to up the limit Wordpress sets on media uploads. I followed advice from some blog I’m not going to mention to raise the limit from 64MB to 2GB.

I did the following:

Created a (php.ini) file in WP ADMIN with the following integers:

upload_max_filesize = 2000MB
post_max_size = 2100MV
memory_limit = 2300MB

I immediately received this error when trying to log into my Wordpress dashboard to check if it worked:

“Allowed memory size of 262144 bytes exhausted (tried to allocate 24576 bytes)"

The above information in this chain helped me tremendously. (Stack usually does BTW)

I modified the PHP.ini file to the following:

upload_max_filesize = 2000M
post_max_size = 2100M
memory_limit = 536870912M

The major difference was only use M, not MB, and set that memory limit high.

As soon as I saved the changed the PHP.ini file, I saved it, went to login again and the login screen reappeared.

I went in and checked media uploads, ands bang:

Image showing twordpress media folder “Add New” box, with limits stated as “MAXIMUM UPLOAD FILE SIZE: 2 GB”

I haven't restarted Apache yet… but all looks good.

Thanks everyone.

@require is NOT only processed when the script is first installed! On my observations it is proccessed on the first execution time! So you can install a script via Greasemonkey's command for creating a brand-new script. The only thing you have to take care about is, that there is no page reload triggered, befor you add the @requirepart. (and save the new script...)

Check into this thread,. However you should be careful as it's documented as "can change upon factory reset". Use at your own risk, and it can be easily changed on a rooted phone. Also it appears as if some manufacturers have had issues with their phones having duplicate numbers thread. Depending on what your trying to do, I probably wouldnt use this as a UID.

This should do it:

<%= f.select :project_id, @project_select, :selected => params[:pid] %>

React Native is primarily developed in JavaScript, which means that most of the code you need to get started can be shared across platforms. React Native will render using native components. React Native apps are developed in the language required by the platform it targets, Objective-C or Swift for iOS, Java for Android, etc. The code written is not shared across platforms and their behavior varies. They have direct access to all features offered by the platform without any restriction.

React is an open-source JavaScript library developed by Facebook for building user interfaces. It's used for handling view layer for web and mobile apps. ReactJS used to create reusable UI components.It is currently one of the most popular JavaScript libraries in the it field and it has strong foundation and large community behind it.If you learn ReactJS, you need to have knowledge of JavaScript, HTML5 and CSS.

I just had the same problem trying to get Spyder to run in Virtual Environment.

The solution is simple:

Activate your virtual environment.

Then pip install Spyder and its dependencies (PyQt5) in your virtual environment.

Then launch Spyder3 from your virtual environment CLI.

It works fine for me now.

The difference between these two methods is:

• parseXxx() returns the primitive type
• valueOf() returns a wrapper object reference of the type.

I prefer to use mutex mechanism in such cases, but if you really want to use boolean, then you should declare it as volatile (to provide the change visibility across threads) and just run the body-less cycle with that boolean as a condition :

//.....some class

volatile boolean someBoolean; 

Thread someThread = new Thread() {

    @Override 
    public void run() {
        //some actions
        while (!someBoolean); //wait for condition 
        //some actions 
    }

};

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

If this is about .css and .js changes, one way is to to "cache busting" is by appending something like "_versionNo" to the file name for each release. For example:

script_1.0.css // This is the URL for release 1.0
script_1.1.css // This is the URL for release 1.1
script_1.2.css // etc.

Or alternatively do it after the file name:

script.css?v=1.0 // This is the URL for release 1.0
script.css?v=1.1 // This is the URL for release 1.1
script.css?v=1.2 // etc.

You can check out this link to see how it could work.

I was getting the same error while connecting my "hr" user of ORCLPDB which is a pluggable database.

First, get hostname and port number by typing a command lsnrctl status on windows command prompt. In my case, it was 127.0.0.1 with port number as 1521

Second, enter the below command with your hostname and port number:

sqlplus username/password@HostName:Port Number/PluggableDatabaseName.

For example:

sqlplus hr/[email protected]:1521/ORCLPDB.

. given a path, how can we recursively create all the folders necessary to create the file .. for that path

Creates all directories and subdirectories as specified by path.

Directory.CreateDirectory(path);

then you may create a file.

Basically, you just have to remove that constraint from the associated view. For instance, if is the height constraint giving warning, just remove it from your view; it will not affect the view.

Is that a proper connection string?
Where is the SQL Server instance located?

You will need to verify that you are able to conenct to SQL Server using the connection string, you specified above.

EDIT: Look at the State property of the recordset to see if it is Open?
Also, change the CursorLocation property to adUseClient before opening the recordset.

These methods are in ObjectNode: the division is such that most read operations are included in JsonNode, but mutations in ObjectNode and ArrayNode.

Note that you can just change first line to be:

ObjectNode jNode = mapper.createObjectNode();
// version ObjectMapper has should return ObjectNode type

or

ObjectNode jNode = (ObjectNode) objectCodec.createObjectNode();
// ObjectCodec is in core part, must be of type JsonNode so need cast

I experienced the same issue with Centos 7, I assume due to an outdated kernel in combination with an updated version of VirtualBox. Based on Blizz's update, this is what worked for me (vagrant-vbguest plugin already installed):

vagrant ssh
sudo yum -y install kernel-devel
sudo yum -y update
exit
vagrant reload --provision

Provided both machines are in the same workgroup, open cmd.exe on the machine you want to connect to, type ipconfig and note the IP at the IPv4 Address line.

Then, on the machine you want to connect with, use http:// + the IP of the target machine.

That should do it.

I tried all suggested answers, but finally i made it work like this

if (false) //your condition
{
    $("a[data-toggle='tab'").prop('disabled', true);
    $("a[data-toggle='tab'").each(function () {
        $(this).prop('data-href', $(this).attr('href')); // hold you original href
        $(this).attr('href', '#'); // clear href
    });                
    $("a[data-toggle='tab'").addClass('disabled-link');
}
else
{
    $("a[data-toggle='tab'").prop('disabled', false);
    $("a[data-toggle='tab'").each(function () {
        $(this).attr('href', $(this).prop('data-href')); // restore original href
    });
    $("a[data-toggle='tab'").removeClass('disabled-link');
}
// if you want to show extra messages that the tab is disabled for a reason
$("a[data-toggle='tab'").click(function(){
   alert('Tab is disabled for a reason');
});

If you want to update to latest version and you don't know what is the latest version you can type.

pip install MySQL_python --upgrade

This will update the MySQL_python for latest version available, you can use for any other package version.

change

public static final String URL = "http://api-Location";

to

public static final String URL = "https://api-Location"

it's happen because i'm using 000webhostapp app

Check to make sure that the file is complete. This error message can occur if you only partially downloaded a file or if it has major issues. Check the MD5sum.

For space-character removal use

"hello world".replace(/\s/g, "");

for all white space use the suggestion by Rocket in the comments below!

Unless I am misunderstanding the question, I would almost always use $this->get_species because the subclass (in this case dog) could overwrite that method since it does extend it. If the class dog doesn't redefine the method then both ways are functionally equivalent but if at some point in the future you decide you want the get_species method in dog should print "dog" then you would have to go back through all the code and change it.

When you use $this it is actually part of the object which you created and so will always be the most up-to-date as well (if the property being used has changed somehow in the lifetime of the object) whereas using the parent class is calling the static class method.

Your setup.py file needs setuptools. Some Python packages used to use distutils for distribution, but most now use setuptools, a more complete package. Here is a question about the differences between them.

To install setuptools on Debian:

sudo apt-get install python3-setuptools

For an older version of Python (Python 2.x):

sudo apt-get install python-setuptools

So, what I was looking for was only where to put the window.location.href and the conclusion I came to was that the best and fastest way to redirect is in routes (that way, we do not wait for anything to load before we redirect).

Like this:

routes: [
    {
        path: "/",
        name: "ExampleRoot",
        component: exampleComponent,
        meta: {
            title: "_exampleTitle"
        },
        beforeEnter: () => {
            window.location.href = 'https://www.myurl.io';
        }
    }]

Maybe it will help someone..

Use window.intro inside of $(document).ready().

If you happen to have multiple accounts on your mac, chances are, your current account belongs to different user group as the primary account that originally owned /usr/local meaning that none of the solutions above will work.

You can check that by trying to ls -la /usr/local and see what user and group that have permissions to write on the directory. In my case it was root wheel. It may be root admin.

I solved it by adding the current user to the group that primary account has by using the following command.

sudo dseditgroup -o edit -a $(whoami) -t user admin
sudo dseditgroup -o edit -a $(whoami) -t user wheel

There after it worked like a charm. Hopefully it helps someone out there.

If the error message is just

"Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.", then grant the login permission for 'NT AUTHORITY\NETWORK SERVICE'

by using

"sp_grantlogin 'NT AUTHORITY\NETWORK SERVICE'" 

else if the error message is like

"Cannot open database "Phaeton.mdf" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'."

try using

"EXEC sp_grantdbaccess 'NT AUTHORITY\NETWORK SERVICE'" 

under your "Phaeton" database.

It turns out that a FTP download call using winscp as last thing to do in the batch caused the problem. After inserting the echo command it works fine. Guess the problems source could be the winscp.exe which do not correctly report the end of the current task to the OS.

del "C:\_ftpcrawler\Account Export.csv" /S /Q

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /console /script="C:\_isource\scripte\data.txt"

echo Download ausgeführt am %date%%time% >> C:\_isource\scripte\data.log

This is a really hacky solution, but it seems to mostly work some of the time. During testing, I noted it sometimes didn't work very well when getting a ^C on the command line, though I did tweak it a bit to behave a bit better.

This hack is an interactive mode hack only, and I am pretty confident that I would not recommend it to anyone. Background commands are likely to cause even less defined behavior than normal. The other answers are a better way of programmatically getting at results.

That being said, here is the "solution":

PROMPT_COMMAND='LAST="`cat /tmp/x`"; exec >/dev/tty; exec > >(tee /tmp/x)'

Set this bash environmental variable and issues commands as desired. $LAST will usually have the output you are looking for:

startide seth> fortune
Courtship to marriage, as a very witty prologue to a very dull play.
                -- William Congreve
startide seth> echo "$LAST"
Courtship to marriage, as a very witty prologue to a very dull play.
                -- William Congreve

This post contains a brilliant trick to detect where the cascade problem is:
Try to replace on Cascade at the time with Cascade.None() until you do not get the error and then you have detected the cascade causing the problem.

Then solve the problem either by changing the original cascade to something else or using Tom Anderson answer.

string str = @"""Hi, "" I am programmer";

OUTPUT - "Hi, " I am programmer

Simplest Definition of Looper & Handler:

Looper is a class that turns a thread into a Pipeline Thread and Handler gives you a mechanism to push tasks into it from any other threads.

Details in general wording:

So a PipeLine Thread is a thread which can accept more tasks from other threads through a Handler.

The Looper is named so because it implements the loop – takes the next task, executes it, then takes the next one and so on. The Handler is called a handler because it is used to handle or accept that next task each time from any other thread and pass to Looper (Thread or PipeLine Thread).

Example:

A Looper and Handler or PipeLine Thread's very perfect example is to download more than one images or upload them to a server (Http) one by one in a single thread instead of starting a new Thread for each network call in the background.

Read more here about Looper and Handler and the definition of Pipeline Thread:

Android Guts: Intro to Loopers and Handlers

You can do something like this:

function getSorted(itemsArray , sortingArr ) {
  var result = [];
  for(var i=0; i<arr.length; i++) {
    result[i] = arr[sortArr[i]];
  }
  return result;
}

You can test it out here.

Note: this assumes the arrays you pass in are equivalent in size, you'd need to add some additional checks if this may not be the case.

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

E Text Editor is great (TextMate compatible sort-of-clone for Windows).

Here is my minimalist example, using a macro. Use double brackets enable_if((...)) when using more complex expressions.

template<bool b, std::enable_if_t<b, int> = 0>
using helper_enable_if = int;

#define enable_if(value) typename = helper_enable_if<value>

struct Test
{
     template<enable_if(false)>
     void run();
}

What worked for me at the end was adding the manifest file to the javaw.exe just like Heikki Juntunen said at https://bugs.eclipse.org/bugs/show_bug.cgi?id=421383#c66

The instructions about how to edit the registry and create the manifest file where written by Matthew Cochrane at https://bugs.eclipse.org/bugs/show_bug.cgi?id=421383#c60 and @KItis wrote the instructions here

I put here a copy of that post:

First you need to add this registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\PreferExternalManifest (DWORD) to 1

Next, a manifest file with the same name as the executable must be present in the same folder as the executable. The file is named eclipse.exe.manifest and consists of:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
    <description>eclipse</description>
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedPrivileges>
                <requestedExecutionLevel xmlns:ms_asmv3="urn:schemas-microsoft-com:asm.v3"
                               level="asInvoker"
                               ms_asmv3:uiAccess="false">
                </requestedExecutionLevel>
            </requestedPrivileges>
        </security>
    </trustInfo>
    <asmv3:application>
        <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">

        </asmv3:windowsSettings>
    </asmv3:application>
</assembly>

Either make an account on the Nuget.org website, then log in, browse to the package you want and click on the Download link on the left menu.

Or guess the URL. They have the following format:

https://www.nuget.org/api/v2/package/{packageID}/{packageVersion}

Then simply unzip the .nupkg file and extract the contents you need.

With all factors put into consideration, with regard to code architecture using modular programming would work very well and with more simplicity in the code. Write a simple

getData() function @returns a 2D array of the data from the database.

pass this funtion to the constructor of the JTabel() constructor i.e

JTabel myTable = new JTable(getData(),columnsArray);

In this case the second argument: columnsArray is a single dimensional array that has the column names

String[] columns = {{"ID","DataOfBirth","Age","Grade","Marks","RegNumber"}};

pass the JTable object to a JScrollPane then you are done, right after adding the ScrollPane to the container ofcourse

JScrollPane scrollPane = new JScrollPane(myTable);

JFrame myFrame = new JFrame();
myFrame.add(scrollPane);

Here is a sample function getData() that queries the database for the data that later is passed on to the JTable

public String[][] getRecords() {
    try (Connection conect = DriverManager.getConnection("jdbc:mysql://localhost:3306/online_students_registration", "root", "")) {
        Statement stm = conect.createStatement();
        String SELECT_QUERY = "SELECT COUNT(*) FROM medicalrecords ;";
        ResultSet cursor = stm.executeQuery(SELECT_QUERY);
        while (cursor.next()) {
            rows = cursor.getInt("COUNT(*)");

My tests show that z-index: 2147483647 is the maximum value, tested on FF 3.0.1 for OS X. I discovered a integer overflow bug: if you type z-index: 2147483648 (which is 2147483647 + 1) the element just goes behind all other elements. At least the browser doesn't crash.

And the lesson to learn is that you should beware of entering too large values for the z-index property because they wrap around.

With the release of TypeScript 3.7, optional chaining (the ? operator) is now officially available.

As such, you can simplify your expression to the following:

const data = change?.after?.data();

You may read more about it from that version's release notes, which cover other interesting features released on that version.

Run the following to install the latest stable release of TypeScript.

npm install typescript

That being said, Optional Chaining can be used alongside Nullish Coalescing to provide a fallback value when dealing with null or undefined values

const data = change?.after?.data() ?? someOtherData();

This will -

• Resize width AND height without the need for a loop
• Doesn't exceed the images original dimensions

//////////////

private void ResizeImage(Image img, double maxWidth, double maxHeight)
{
    double resizeWidth = img.Source.Width;
    double resizeHeight = img.Source.Height;

    double aspect = resizeWidth / resizeHeight;

    if (resizeWidth > maxWidth)
    {
        resizeWidth = maxWidth;
        resizeHeight = resizeWidth / aspect;
    }
    if (resizeHeight > maxHeight)
    {
        aspect = resizeWidth / resizeHeight;
        resizeHeight = maxHeight;
        resizeWidth = resizeHeight * aspect;
    }

    img.Width = resizeWidth;
    img.Height = resizeHeight;
}

I'm afraid the only way to do this without explicitly specifying the width is to use (gasp) tables.

What worked me is that I copied all the code inside the broken class and removed that file. Then, I opened an empty file with the same name and pasted back.

Result: beautiful syntax highlights came back!

To get the device id, connect your phone to USB and open logcat in android studio Use the code below (make sure you have USB debugging enabled in your device). Then open any app (download any random app from play store) which has google Ad. In the Logcat type "set" as shown in the image. Your device id is shown highlighted in the image as

setTestDeviceIds(Arrays.asList("CC9DW7W7R4H0NM3LT9OLOF7455F8800D")).

Use the Test Device in your code as shown

val adRequest = AdRequest
        .Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("CC9DW7W7R4H0NM3LT9OLOF7455F8800D")
        .build()

While I was waiting for someone to respond, I looked around a bit more and found the answer.

I guess you are asking why is 1388516401 equal to 2014-01-01...?

There is an historical reason for that. There is a 32-bit integer variable, called time_t, that keeps the count of the time elapsed since 1970-01-01 00:00:00. Its value expresses time in seconds. This means that in 2014-01-01 00:00:01 time_t will be equal to 1388516401.

This leads us for sure to another interesting fact... In 2038-01-19 03:14:07 time_t will reach 2147485547, the maximum value for a 32-bit number. Ever heard about John Titor and the Year 2038 problem? :D

The simple way to do it. All you need is to put the decorator method outside the class. You can still use it inside.

def my_decorator(func):
    #this is the key line. There's the aditional self parameter
    def wrap(self, *params, **kwargs):
        # you can use self here as if you were inside the class
        return func()
    return wrap

class Test(object):
    @my_decorator
    def bar(self):
        pass

Since it has not been suggested yet, I'm pretty sure LOAD DATA INFILE is still the fastest way to load data as it disables indexing, inserts all data, and then re-enables the indexes - all in a single request.

Saving the data as a csv should be fairly trivial keeping in mind fputcsv. MyISAM is fastest, but you still get big performance in InnoDB. There are other disadvantages, though so I would go this route if you are inserting a lot of data, and not bother with under 100 rows.

Try adding this to your web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/your-servlet-name.xml
    </param-value>

To complete @SamSaffron's answer :

You can use class_name with either foreign_key or inverse_of. I personally prefer the more abstract declarative, but it's really just a matter of taste :

class BlogPost
  has_many :images, class_name: "BlogPostImage", inverse_of: :blog_post  
end

and you need to make sure you have the belongs_to attribute on the child model:

class BlogPostImage
  belongs_to :blog_post
end

You can simply use this chrome extension Allow-Control-Allow-Origin

just click the icon of the extensnion to turn enable cross-resource sharing ON or OFF as you want

For better viewing with sqlplus

If you're using sqlplus you may want to first set up a few parameters for nicer viewing if your columns are getting mangled (these variables should not persist after you exit your sqlplus session ):

set colsep '|'
set linesize 167
set pagesize 30
set pagesize 1000

Show All Tables

You can then use something like this to see all table names:

SELECT table_name, owner, tablespace_name FROM all_tables;

Show Tables You Own

As @Justin Cave mentions, you can use this to show only tables that you own:

SELECT table_name FROM user_tables;

Don't Forget about Views

Keep in mind that some "tables" may actually be "views" so you can also try running something like:

SELECT view_name FROM all_views;

The Results

This should yield something that looks fairly acceptable like:

Adding the padding is rather... fiddly. Here's the function I wrote with the help of the comments in this thread as well as the wiki page for base64 (it's surprisingly helpful) https://en.wikipedia.org/wiki/Base64#Padding.

import logging
import base64
def base64_decode(s):
    """Add missing padding to string and return the decoded base64 string."""
    log = logging.getLogger()
    s = str(s).strip()
    try:
        return base64.b64decode(s)
    except TypeError:
        padding = len(s) % 4
        if padding == 1:
            log.error("Invalid base64 string: {}".format(s))
            return ''
        elif padding == 2:
            s += b'=='
        elif padding == 3:
            s += b'='
        return base64.b64decode(s)

The warning appears only because the demo code has:

function TabPanel(props) {
  const { children, value, index, ...other } = props;

  return (
    <div
      role="tabpanel"
      hidden={value !== index}
      id={`simple-tabpanel-${index}`}
      aria-labelledby={`simple-tab-${index}`}
      {...other}
    >
      {value === index && (
        <Box p={3}>  // <==NOTE P TAG HERE
          <Typography>{children}</Typography>
        </Box>
      )}
    </div>
  );
}

Changing it like this takes care of it:

function TabPanel(props) {
    const {children, value, index, classes, ...other} = props;

    return (
        <div
            role="tabpanel"
            hidden={value !== index}
            id={`simple-tabpanel-${index}`}
            aria-labelledby={`simple-tab-${index}`}
            {...other}
        >
            {value === index && (
                <Container>
                    <Box>   // <== P TAG REMOVED
                        {children}
                    </Box>
                </Container>
            )}
        </div>
    );
}

I see that no good desciption for using numpy.nditer() is here. So, I am gonna go with one. According to NumPy v1.21 dev0 manual, The iterator object nditer, introduced in NumPy 1.6, provides many flexible ways to visit all the elements of one or more arrays in a systematic fashion.

I have to calculate mean_squared_error and I have already calculate y_predicted and I have y_actual from the boston dataset, available with sklearn.

def cal_mse(y_actual, y_predicted):
    """ this function will return mean squared error
       args:
           y_actual (ndarray): np array containing target variable
           y_predicted (ndarray): np array containing predictions from DecisionTreeRegressor
       returns:
           mse (integer)
    """
    sq_error = 0
    for i in np.nditer(np.arange(y_pred.shape[0])):
        sq_error += (y_actual[i] - y_predicted[i])**2
    mse = 1/y_actual.shape[0] * sq_error
    
    return mse

This works, I tested it in AppJet (you can copy-paste the code on its IDE and press "reload" to see it work, don't need to create an account)

/* appjet:version 0.1 */
function Joes_remove(someArray) {
    var newArray = [];
    var element;
    for( element in someArray){
        if(someArray[element]!=undefined ) {
            newArray.push(someArray[element]);
        }
    }
    return newArray;
}

var myArray2 = [1,2,,3,,3,,,0,,,4,,4,,5,,6,,,,];

print("Original array:", myArray2);
print("Clenased array:", Joes_remove(myArray2) );
/*
Returns: [1,2,3,3,0,4,4,5,6]
*/

I think one of the Advantages of code first is that you can back up all the changes you've made to a version control system like Git. Because all your tables and relationships are stored in what are essentially just classes, you can go back in time and see what the structure of your database was before.

 scope: false
 transclude: false

and you will have the same scope(with parent element)

$scope.$watch(...

There are a lot of ways how to access parent scope depending on this two options scope& transclude.

Below is a simple function decorator which allows to track how much memory the process consumed before the function call, after the function call, and what is the difference:

import time
import os
import psutil
 
 
def elapsed_since(start):
    return time.strftime("%H:%M:%S", time.gmtime(time.time() - start))
 
 
def get_process_memory():
    process = psutil.Process(os.getpid())
    mem_info = process.memory_info()
    return mem_info.rss
 
 
def profile(func):
    def wrapper(*args, **kwargs):
        mem_before = get_process_memory()
        start = time.time()
        result = func(*args, **kwargs)
        elapsed_time = elapsed_since(start)
        mem_after = get_process_memory()
        print("{}: memory before: {:,}, after: {:,}, consumed: {:,}; exec time: {}".format(
            func.__name__,
            mem_before, mem_after, mem_after - mem_before,
            elapsed_time))
        return result
    return wrapper

Here is my blog which describes all the details. (archived link)

I believe what you're trying to do is impossible.

The junk that BinaryFormatter creates is necessary to recover the object from the file after your program stopped.
However it is possible to get the object data, you just need to know the exact size of it (more difficult than it sounds) :

public static unsafe byte[] Binarize(object obj, int size)
{
    var r = new byte[size];
    var rf = __makeref(obj);
    var a = **(IntPtr**)(&rf);
    Marshal.Copy(a, r, 0, size);
    return res;
}

this can be recovered via:

public unsafe static dynamic ToObject(byte[] bytes)
{
    var rf = __makeref(bytes);
    **(int**)(&rf) += 8;
    return GCHandle.Alloc(bytes).Target;
}

The reason why the above methods don't work for serialization is that the first four bytes in the returned data correspond to a RuntimeTypeHandle. The RuntimeTypeHandle describes the layout/type of the object but the value of it changes every time the program is ran.

EDIT: that is stupid don't do that --> If you already know the type of the object to be deserialized for certain you can switch those bytes for BitConvertes.GetBytes((int)typeof(yourtype).TypeHandle.Value) at the time of deserialization.

Yes. First, hook into the column added event:

this.dataGridView1.ColumnAdded += new DataGridViewColumnEventHandler(dataGridView1_ColumnAdded);

Then, in your event handler, just append the text you want to:

private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)
{
    e.Column.HeaderText += additionalHeaderText;
}

Maybe your rmiregistry not be created before client trying connect to your server and it would lead to this exception.In Linux, you can use "netstat" to check your rmiregistry be bond on the right port you assigned in java code.

Another interesting solution in ORACLE PL/SQL:

    SELECT LEVEL n
      FROM DUAL
CONNECT BY LEVEL <= 100;

<input type="text" id="subEmail" onchange="checkFilled();">

JavaScript

 function checkFilled() {
    var inputVal = document.getElementById("subEmail");
    if (inputVal.value == "") {
        inputVal.style.backgroundColor = "yellow";
    }
    else{
        inputVal.style.backgroundColor = "";
    }
}

checkFilled();

Note: You were checking value and setting color to value which is not allowed, that's why it was giving you errors. try like the above.

'-replace' does a regex search and you have special characters in that last one (like +) So you might use the non-regex replace version like this:

$c = $c.replace('AccountKey=eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR/Zd/KXoKvSdjlUiiWyVV2+OUFOrVsd7jrzhldJPmfBBpQA==','DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN+WVBJNWzqcQpWtZf10tgFhKrnN48lXA==')

This Blog article explains the internals of ODEX files:

WHAT IS AN ODEX FILE?

In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

• If you just want to sort the array values and don't care for the keys, use sort(). This will give a new array with numeric keys starting from 0.
• If you want to keep the key-value associations, use asort().

See also the comparison table of sorting functions in PHP.

See jQuery.scroll(). You can bind this to the window element to get your desired event hook.

On scroll, then simply check your scroll position:

$(window).scroll(function() {
  var scrollTop = $(window).scrollTop();
  if ( scrollTop > $(headerElem).offset().top ) { 
    // display add
  }
});

In Controller i have specified the below code with ActionResult which is a base class that can have 11 subtypes in MVC like: ViewResult, PartialViewResult, EmptyResult, RedirectResult, RedirectToRouteResult, JsonResult, JavaScriptResult, ContentResult, FileContentResult, FileStreamResult, FilePathResult.

    public ActionResult Index()
                {
                    if (HttpContext.Session["LoggedInUser"] == null)
                    {
                        return RedirectToAction("Login", "Home");
                    }

                    else
                    {
                        return View(); // returns ViewResult
                    }

                }
//More Examples

    [HttpPost]
    public ActionResult Index(string Name)
    {
     ViewBag.Message = "Hello";
     return Redirect("Account/Login"); //returns RedirectResult
    }

    [HttpPost]
    public ActionResult Index(string Name)
    {
    return RedirectToRoute("RouteName"); // returns RedirectToRouteResult
    }

Likewise we can return all these 11 subtypes by using ActionResult() without specifying every subtype method explicitly. ActionResult is the best thing if you are returning different types of views.

I recommend using the short ' instead of ". If you do so, you wont longer have to escape the double quote (\").

In that case you would write

echo '<a href="http://www.whatever.com/'. $param .'">Click Here</a>';

But look onto nicolaas' answer "what you really should do" to learn how to produce cleaner code.

Assuming the OP wants a Java answer:

As of JDBC3 / Java 6 there's the isValid() method which should be used rather than inventing one's own method.

The implementer of the driver is required to execute some sort of query against the database when this method id called. You - as a mere JDBC user - do not have to know or understand what this query is. All you have to do is to trust that the creator of the JDBC driver has done his/her work properly.

If a point is inside a rectangle. On a plane. For mathematician or geodesy (GPS) coordinates

• Let the rectangle be set by vertices A, B, C, D. The point is P. Coordinates are rectangular: x, y.
• Lets prolong the sides of the rectangle. So we have 4 straight lines l_AB, l_BC, l_CD, l_DA, or, for shortness, l₁, l₂, l₃, l₄.

• Make an equation for every l_i. The equation sort of:

  f_i(P)=0.

P is a point. For points, belonging to l_i, the equation is true.

• We need the functions on the left sides of the equations. They are f₁, f₂, f₃, f₄.
• Notice, that for every point from one side of l_i the function f_i is greater than 0, for points from the other side f_i is lesser than 0.
• So, if we are checking for P being in rectangle, we only need for the p to be on correct sides of all four lines. So, we have to check four functions for their signs.
• But what side of the line is the correct one, to which the rectangle belongs? It is the side, where lie the vertices of rectangle that don't belong to the line. For checking we can choose anyone of two not belonging vertices.

• So, we have to check this:

  f_AB(P) f_AB(C) >= 0

  f_BC(P) f_BC(D) >= 0

  f_CD(P) f_CD(A) >= 0

  f_DA(P) f_DA(B) >= 0

The unequations are not strict, for if a point is on the border, it belongs to the rectangle, too. If you don't need points on the border, you can change inequations for strict ones. But while you work in floating point operations, the choice is irrelevant.

• For a point, that is in the rectangle, all four inequations are true. Notice, that it works also for every convex polygon, only the number of lines/equations will differ.

• The only thing left is to get an equation for a line going through two points. It is a well-known linear equation. Let's write it for a line AB and point P:

  f_AB(P)   =   (x_A-x_B) (y_P-y_B) - (y_A-y_B) (x_P-x_B)

The check could be simplified - let's go along the rectangle clockwise - A, B, C, D, A. Then all correct sides will be to the right of the lines. So, we needn't compare with the side where another vertice is. And we need check a set of shorter inequations:

f_AB(P) >= 0

f_BC(P) >= 0

f_CD(P) >= 0

f_DA(P) >= 0

But this is correct for the normal, mathematician (from the school mathematics) set of coordinates, where X is to the right and Y to the top. And for the geodesy coordinates, as are used in GPS, where X is to the top, and Y is to the right, we have to turn the inequations:

f_AB(P) <= 0

f_BC(P) <= 0

f_CD(P) <= 0

f_DA(P) <= 0

If you are not sure with the directions of axes, be careful with this simplified check - check for one point with the known placement, if you have chosen the correct inequations.

Solution 1. Set your TableLayout tl as class member variable, only call TableLayout tl=(TableLayout)findViewById(R.id.maintable); when you initiate the class. When button clicked use tl directly, eg. tl.addView(row), don't call FindViewById anymore. So the next new row wouldn't replace the previous new row.

Solution 2. Everytime after button click save your updated data into an array, and then re-render your whole table layout by loop through the array.

You need to install this

Adding another answer that does not involve coordinates.

This will bring your desired view to focus (but not to the top position) :

  yourView.getParent().requestChildFocus(yourView,yourView);

public void RequestChildFocus (View child, View focused)

child - The child of this ViewParent that wants focus. This view will contain the focused view. It is not necessarily the view that actually has focus.

focused - The view that is a descendant of child that actually has focus

I ran to a similar problem and that was just because of the extra spaces:

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

which when removed works fine:

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

you can do this with annotations like this

 @Value("#{T(java.util.Arrays).asList('${my.list.of.strings:a,b,c}')}") 
    private List<String> mylist;

here my.list.of.strings will be picked from the properties file, if its not there, then the defaults a,b,c will be used

and in your properties file, you can have something like this

my.list.of.strings=d,e,f

This will search text in all the td's inside each tr and show/hide tr's based on search text

 $.each($(".table tbody").find("tr"), function () {                              

                if ($(this).text().toLowerCase().replace(/\s+/g, '').indexOf(searchText.replace(/\s+/g, '').toLowerCase()) == -1)
                    $(this).hide();
                else
                    $(this).show();
 });

I tried to do this in next way

public static DataTable JoinTwoTables(DataTable innerTable, DataTable outerTable)
        {
            DataTable resultTable = new DataTable();
            var innerTableColumns = new List<string>();
            foreach (DataColumn column in innerTable.Columns)
            {
                innerTableColumns.Add(column.ColumnName);
                resultTable.Columns.Add(column.ColumnName);
            }

            var outerTableColumns = new List<string>();
            foreach (DataColumn column in outerTable.Columns)
            {
                if (!innerTableColumns.Contains(column.ColumnName))
                {
                    outerTableColumns.Add(column.ColumnName);
                    resultTable.Columns.Add(column.ColumnName);
                }                    
            }

            for (int i = 0; i < innerTable.Rows.Count; i++)
            {
                var row = resultTable.NewRow();
                innerTableColumns.ForEach(x =>
                {
                    row[x] = innerTable.Rows[i][x];
                });
                outerTableColumns.ForEach(x => 
                {
                    row[x] = outerTable.Rows[i][x];
                });
                resultTable.Rows.Add(row);
            }
            return resultTable;
        }

Using the onclick attribute or applying a function to your JS onclick properties will erase your onclick initialization in <head>.

What you need to do is add click events on your button. To do that you’ll need the addEventListener or attachEvent (IE) method.

<!DOCTYPE html>
<html>
<head>
    <script>
        function addEvent(obj, event, func) {
            if (obj.addEventListener) {
                obj.addEventListener(event, func, false);
                return true;
            } else if (obj.attachEvent) {
                obj.attachEvent('on' + event, func);
            } else {
                var f = obj['on' + event];
                obj['on' + event] = typeof f === 'function' ? function() {
                    f();
                    func();
                } : func
            }
        }

        function f1()
        {
            alert("f1 called");
            //form validation that recalls the page showing with supplied inputs.    
        }
    </script>
</head>

    <script>
        addEvent(document.getElementById('Save'), 'click', function() {
            alert('hello');
        });

The tutorial link you provided seems to suggest that you need to set the layout_width and layout_height properties, of your child elements to match_parent.

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

(^|\s) would match space or start of string and ($|\s) for space or end of string. Together it's:

(^|\s)stackoverflow($|\s)

Arrays are allocated memory at compile time in java, so they are static, the elements not explicitly set or modified are set with the default values. You could use some code like this, though it is not recommended as it does not count default values, even if you explicitly initialize them that way, it is also likely to cause bugs down the line. As others said, when looking for the actual size, ".length" must be used instead of ".length()".

public int logicalArrayLength(type[] passedArray) {
    int count = 0;
    for (int i = 0; i < passedArray.length; i++) {
        if (passedArray[i] != defaultValue) {
            count++;
        }
    }
    return count;
}

(New) Expanded Auto Mode: \x auto

New for Postgresql 9.2; PSQL automatically fits records to the width of the screen. previously you only had expanded mode on or off and had to switch between the modes as necessary.

• If the record can fit into the width of the screen; psql uses normal formatting.
• If the record can not fit into the width of the screen; psql uses expanded mode.

To get this use: \x auto

Postgresql 9.5 Documentation on PSQL command.

Wide screen, normal formatting:

How to start psql with \x auto?

Configure \x auto command on startup by adding it to .psqlrc in your home folder and restarting psql. Look under 'Files' section in the psql doc for more info.

~/.psqlrc

\x auto

Similar to Luke's answer, but with GET.

Place this php-code in a php-page, ex. getpage.php:

<?php
$_SESSION['size'] = $_GET['size'];
?>

Then call it with a jQuery script like this:

$.get( "/getpage.php?size=1");

Agree with Federico. In some cases you may run into problems using POST, although not sure if it can be browser related.

Sometimes the Maven command line is sufficient when scripting something related to the project version, e.g. for artifact retrieval via URL from a repository:

mvn help:evaluate -Dexpression=project.version -q -DforceStdout

Usage example:

VERSION=$( mvn help:evaluate -Dexpression=project.version -q -DforceStdout )
ARTIFACT_ID=$( mvn help:evaluate -Dexpression=project.artifactId -q -DforceStdout )
GROUP_ID_URL=$( mvn help:evaluate -Dexpression=project.groupId -q -DforceStdout | sed -e 's#\.#/#g' )
curl -f -S -O http://REPO-URL/mvn-repos/${GROUP_ID_URL}/${ARTIFACT_ID}/${VERSION}/${ARTIFACT_ID}-${VERSION}.jar

I would like just to add that if you want to use windows socket library you have to :

I don't think you can delete from multiple tables at once (though I'm not certain).

It sounds to me, however, that you would be best to achieve this effect with a relationship that cascades deletes. If you did this you would be able to delete the record from one table and the records in the other would be automatically deleted.

As an example, say the two tables represent a customer, and the customer's orders. If you setup the relationship to cascade deletes, you could simply delete record in the customer table, and the orders would get deleted automatically.

See the MSDN doc on cascading referential integrity constraints.

You can simply export the table with a query clause using datapump and import it back with table_exists_action=replace clause. Its will drop and recreate your table and take very less time. Please read about it before implementing.

Assuming the expectation is just going to be two windows popping up (one of the parent and one for the popup) then just wait for two windows to come up, find the other window handle and switch to it.

WebElement link = // element that will showModalDialog()

// Click on the link, but don't wait for the document to finish
final JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript(
    "var el=arguments[0]; setTimeout(function() { el.click(); }, 100);",
  link);

// wait for there to be two windows and choose the one that is 
// not the original window
final String parentWindowHandle = driver.getWindowHandle();
new WebDriverWait(driver, 60, 1000)
    .until(new Function<WebDriver, Boolean>() {
    @Override
    public Boolean apply(final WebDriver driver) {
        final String[] windowHandles =
            driver.getWindowHandles().toArray(new String[0]);
        if (windowHandles.length != 2) {
            return false;
        }
        if (windowHandles[0].equals(parentWindowHandle)) {
            driver.switchTo().window(windowHandles[1]);
        } else {
            driver.switchTo().window(windowHandles[0]);
        }
        return true;
    }
});

What about this?

return ((num + "").charAt(0) == '-');

Use this code for API 21 or above. This works and gives better result compared to the other answers, it detects perfectly the foreground process.

if (Build.VERSION.SDK_INT >= 21) {
    String currentApp = null;
    UsageStatsManager usm = (UsageStatsManager) this.getSystemService(Context.USAGE_STATS_SERVICE);
    long time = System.currentTimeMillis();
    List<UsageStats> applist = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
    if (applist != null && applist.size() > 0) {
        SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
        for (UsageStats usageStats : applist) {
            mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);

        }
        if (mySortedMap != null && !mySortedMap.isEmpty()) {
            currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
        }
    }

1) When to use include directive ?

To prevent duplication of same output logic across multiple jsp's of the web app ,include mechanism is used ie.,to promote the re-usability of presentation logic include directive is used

  <%@ include file="abc.jsp" %>

when the above instruction is received by the jsp engine,it retrieves the source code of the abc.jsp and copy's the same inline in the current jsp. After copying translation is performed for the current page

Simply saying it is static instruction to jsp engine ie., whole source code of "abc.jsp" is copied into the current page

2) When to use include action ?

include tag doesn't include the source code of the included page into the current page instead the output generated at run time by the included page is included into the current page response

include tag functionality is similar to that of include mechanism of request dispatcher of servlet programming

include tag is run-time instruction to jsp engine ie., rather copying whole code into current page a method call is made to "abc.jsp" from current page

You can use the instanceof operator to test to see if it is a double prior to casting. You can then safely cast it to a double. In addition you can test it against other known types (e.g. Integer) and then coerce them into a double manually if desired.

    Double d = null;
    if (obj instanceof Double) {
        d = (Double) obj;
    }

just combine the value and the stud_name e.g. 1_sre and split the value when get it into php. Javascript seems like hammer to crack a nut. N.B. this method assumes you can edit the the html. Here is what the html might look like:

<form name='add'>
Age: <select name='age'>
     <option value='1_sre'>23</option>
     <option value='2_sam>24</option>
     <option value='5_john>25</option>
     </select>
<input type='submit' name='submit'/>
</form>

If you want a generic solution without boxing:

public class KeyBasedEqualityComparer<T, TKey> : IEqualityComparer<T>
{
    private readonly Func<T, TKey> _keyGetter;

    public KeyBasedEqualityComparer(Func<T, TKey> keyGetter)
    {
        _keyGetter = keyGetter;
    }

    public bool Equals(T x, T y)
    {
        return EqualityComparer<TKey>.Default.Equals(_keyGetter(x), _keyGetter(y));
    }

    public int GetHashCode(T obj)
    {
        TKey key = _keyGetter(obj);

        return key == null ? 0 : key.GetHashCode();
    }
}

public static class KeyBasedEqualityComparer<T>
{
    public static KeyBasedEqualityComparer<T, TKey> Create<TKey>(Func<T, TKey> keyGetter)
    {
        return new KeyBasedEqualityComparer<T, TKey>(keyGetter);
    }
}

usage:

KeyBasedEqualityComparer<Class_reglement>.Create(x => x.Numf)

Sam's solution worked for me, but I didn't want to run as admin as a permanent solution.

This is how I solved it in my case:

1. Run CMD as admin
2. Type "netsh http show urlacl" and find the reserved url with the relevant port
3. Type "netsh http delete urlacl url=YourReservedUrlHere"

After that I could run my app without the need for admin rights. But it did messed with the ability to browse to my app from an external computer. Close enough for me for now.

It is possible also that one may want to have personalized feature branches where code is just placed at the end of day. That permits to track development in finer detail.

I would not want to pollute master development with non-working code, thus doing --no-ff may just be what one is looking for.

As a side note, it may not be necessary to commit working code on a personalized branch, since history can be rewritten git rebase -i and forced on the server as long as nobody else is working on that same branch.

Collections.singletonList(messageBody)

If you'd need to have a list of one item!

Collections is from java.util package.

Here is how I author custom events:

var event = jQuery.Event('customEventName');
$(element).trigger(event);

Granted, you could simply do

$(element).trigger('eventname');

But the way I wrote allows you to detect whether the user has prevented default or not by doing

var prevented = event.isDefaultPrevented();

This allows you to listen to your end-user's request to stop processing a particular event, such as if you click a button element in a form but do not want to the form to post if there is an error.

I then usually listen to events like so

$(element).off('eventname.namespace').on('eventname.namespace', function () {
    ...
});

Once again, you could just do

$(element).on('eventname', function () {
    ...
});

But I've always found this somewhat unsafe, especially if you're working in a team.

There is nothing wrong with the following:

$(element).on('eventname', function () {});

However, assume that I need to unbind this event for whatever reason (imagine a disabled button). I would then have to do

$(element).off('eventname', function () {});

This will remove all eventname events from $(element). You cannot know whether someone in the future will also bind an event to that element, and you'd be inadvertently unbinding that event as well

The safe way to avoid this is to namespace your events by doing

$(element).on('eventname.namespace', function () {});

Lastly, you may have noticed that the first line was

$(element).off('eventname.namespace').on('eventname.namespace', ...)

I personally always unbind an event before binding it just to make sure that the same event handler never gets called multiple times (imagine this was the submit button on a payment form and the event had been bound 5 times)

• How to change any string date to object date (also with moment.js):

startDate = moment(sDate); endDate = moment(eDate);

My favorite: Smart::Comments

use Smart::Comments;
# ...

### %hash

That's it.

Here's an example of how you might concatenate email addresses from a table into a single @recipients parameter:

CREATE TABLE #emailAddresses (email VARCHAR(25))

INSERT #emailAddresses (email) VALUES ('[email protected]')
INSERT #emailAddresses (email) VALUES ('[email protected]')
INSERT #emailAddresses (email) VALUES ('[email protected]')

DECLARE @recipients VARCHAR(MAX)
SELECT @recipients = COALESCE(@recipients + ';', '') + email 
FROM #emailAddresses

SELECT @recipients

DROP TABLE #emailAddresses

The resulting @recipients will be:

[email protected];[email protected];[email protected]

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

$.ready(function() {
    createGrid();
});

This is in case when you dont use AJAX to load your div

My personal preference here is rewriting the query or working with a namevaluecollection at a lower point, but there are times where the business logic makes neither of those very helpful and sometimes reflection really is what you need. In those circumstances you can just turn off the readonly flag for a moment like so:

// reflect to readonly property
PropertyInfo isreadonly = typeof(System.Collections.Specialized.NameValueCollection).GetProperty("IsReadOnly", BindingFlags.Instance | BindingFlags.NonPublic);

// make collection editable
isreadonly.SetValue(this.Request.QueryString, false, null);

// remove
this.Request.QueryString.Remove("foo");

// modify
this.Request.QueryString.Set("bar", "123");

// make collection readonly again
isreadonly.SetValue(this.Request.QueryString, true, null);

It all depends on what you are trying to achieve with "saving locally". Do you want to allow the user to download the file? then <a download> is the way to go. Do you want to save it locally, so you can restore your application state? Then you might want to look into the various options of WebStorage. Specifically localStorage or IndexedDB. The FilesystemAPI allows you to create local virtual file systems you can store arbitrary data in.

and also I wrote a script below to make it for me:

   #!/bin/sh
   # stop chrome update from repository file
   sudo -s<<END
   touch /etc/default/google-chrome
   echo "repo_add_once=false" > /etc/default/google-chrome
   END

Also Disable Chromium Auto Update in Linux page states the same procedure.

This is an old question, but I stumbled across it and thought I'd share the method I used:

var body = '<div id="anid">some <a href="link">text</a></div> and some more text';
var temp = document.createElement("div");
temp.innerHTML = body;
var sanitized = temp.textContent || temp.innerText;

sanitized will now contain: "some text and some more text"

Simple, no jQuery needed, and it shouldn't let you down even in more complex cases.

Simple-to-code O(N + K*log(K)) way

Take a random sample without replacement of the indices, sort the indices, and take them from the original.

indices = random.sample(range(len(myList)), K)
[myList[i] for i in sorted(indices)]

Or more concisely:

[x[1] for x in sorted(random.sample(enumerate(myList),K))]

Optimized O(N)-time, O(1)-auxiliary-space way

You can alternatively use a math trick and iteratively go through myList from left to right, picking numbers with dynamically-changing probability (N-numbersPicked)/(total-numbersVisited). The advantage of this approach is that it's an O(N) algorithm since it doesn't involve sorting!

from __future__ import division

def orderedSampleWithoutReplacement(seq, k):
    if not 0<=k<=len(seq):
        raise ValueError('Required that 0 <= sample_size <= population_size')

    numbersPicked = 0
    for i,number in enumerate(seq):
        prob = (k-numbersPicked)/(len(seq)-i)
        if random.random() < prob:
            yield number
            numbersPicked += 1

Proof of concept and test that probabilities are correct:

Simulated with 1 trillion pseudorandom samples over the course of 5 hours:

>>> Counter(
        tuple(orderedSampleWithoutReplacement([0,1,2,3], 2))
        for _ in range(10**9)
    )
Counter({
    (0, 3): 166680161, 
    (1, 2): 166672608, 
    (0, 2): 166669915, 
    (2, 3): 166667390, 
    (1, 3): 166660630, 
    (0, 1): 166649296
})

Probabilities diverge from true probabilities by less a factor of 1.0001. Running this test again resulted in a different order meaning it isn't biased towards one ordering. Running the test with fewer samples for [0,1,2,3,4], k=3 and [0,1,2,3,4,5], k=4 had similar results.

edit: Not sure why people are voting up wrong comments or afraid to upvote... NO, there is nothing wrong with this method. =)

(Also a useful note from user tegan in the comments: If this is python2, you will want to use xrange, as usual, if you really care about extra space.)

edit: Proof: Considering the uniform distribution (without replacement) of picking a subset of k out of a population seq of size len(seq), we can consider a partition at an arbitrary point i into 'left' (0,1,...,i-1) and 'right' (i,i+1,...,len(seq)). Given that we picked numbersPicked from the left known subset, the remaining must come from the same uniform distribution on the right unknown subset, though the parameters are now different. In particular, the probability that seq[i] contains a chosen element is #remainingToChoose/#remainingToChooseFrom, or (k-numbersPicked)/(len(seq)-i), so we simulate that and recurse on the result. (This must terminate since if #remainingToChoose == #remainingToChooseFrom, then all remaining probabilities are 1.) This is similar to a probability tree that happens to be dynamically generated. Basically you can simulate a uniform probability distribution by conditioning on prior choices (as you grow the probability tree, you pick the probability of the current branch such that it is aposteriori the same as prior leaves, i.e. conditioned on prior choices; this will work because this probability is uniformly exactly N/k).

edit: Timothy Shields mentions Reservoir Sampling, which is the generalization of this method when len(seq) is unknown (such as with a generator expression). Specifically the one noted as "algorithm R" is O(N) and O(1) space if done in-place; it involves taking the first N element and slowly replacing them (a hint at an inductive proof is also given). There are also useful distributed variants and miscellaneous variants of reservoir sampling to be found on the wikipedia page.

edit: Here's another way to code it below in a more semantically obvious manner.

from __future__ import division
import random

def orderedSampleWithoutReplacement(seq, sampleSize):
    totalElems = len(seq)
    if not 0<=sampleSize<=totalElems:
        raise ValueError('Required that 0 <= sample_size <= population_size')

    picksRemaining = sampleSize
    for elemsSeen,element in enumerate(seq):
        elemsRemaining = totalElems - elemsSeen
        prob = picksRemaining/elemsRemaining
        if random.random() < prob:
            yield element
            picksRemaining -= 1

from collections import Counter         
Counter(
    tuple(orderedSampleWithoutReplacement([0,1,2,3], 2))
    for _ in range(10**5)

)

Just open the R(software) and copy and paste

system("defaults write org.R-project.R force.LANG en_US.UTF-8")

Hope this will work fine or use the other method

open(on mac): Utilities/Terminal copy and paste

defaults write org.R-project.R force.LANG en_US.UTF-8

and close both terminal and R and reopen R.

Just make sure put single space before and after "and" Keyword..

You can try

echo implode(', ', (array)$ret);

I know this is kinda late answer but another way besides yannick's answer https://stackoverflow.com/a/57062363/6603342 to use ! is to cast it as string thus telling TypeScript i am sure this is a string thus converting

let name1:string = person.name;//<<<Error here 

to

let name1:string = person.name as string;

This will make the error go away but if by any chance this is not a string you will get a run-time error which is one of the reassons we are using TypeScript to ensure that the type matches and avoid such errors at compile time.

I have struggled with a similar issue for one day... My Scenario:

I have a SpringBoot application and I use applicationContext.xml in scr/main/resources to configure all my Spring Beans. For testing(integration testing) I use another applicationContext.xml in test/resources and things worked as I have expected: Spring/SpringBoot would override applicationContext.xml from scr/main/resources and would use the one for Testing which contained the beans configured for testing.

However, just for one UnitTest I wanted yet another customization for the applicationContext.xml used in Testing, just for this Test I wanted to used some mockito beans, so I could mock and verify, and here started my one day head-ache!

The problem is that Spring/SpringBoot doesn't not override the applicationContext.xml from scr/main/resources ONLY IF the file from test/resources HAS the SAME NAME. I tried for hours to use something like:

@RunWith(SpringJUnit4ClassRunner.class)
@OverrideAutoConfiguration(enabled=true)
@ContextConfiguration({"classpath:applicationContext-test.xml"})

it did not work, Spring was first loading the beans from applicationContext.xml in scr/main/resources

My solution based on the answers here by @myroch and @Stuart:

1. Define the main configuration of the application:

   @Configuration @ImportResource({"classpath:applicationContext.xml"}) public class MainAppConfig { }

this is used in the application

@SpringBootApplication
@Import(MainAppConfig.class)
public class SuppressionMain implements CommandLineRunner

2. Define a TestConfiguration for the Test where you want to exclude the main configuration

   @ComponentScan( basePackages = "com.mypackage", excludeFilters = { @ComponentScan.Filter(type = ASSIGNABLE_TYPE, value = {MainAppConfig.class}) }) @EnableAutoConfiguration public class TestConfig { }

By doing this, for this Test, Spring will not load applicationContext.xml and will load only the custom configuration specific for this Test.

Lets say your data is -

data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }

You can use the data.items() method to get the dictionary elements. Note, in django templates we do NOT put (). Also some users mentioned values[0] does not work, if that is the case then try values.items.

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>

    {% for key, values in data.items %}
    <tr>
        <td>{{key}}</td>
        {% for v in values[0] %}
        <td>{{v}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

Am pretty sure you can extend this logic to your specific dict.

To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.

return render_to_response('some_page.html', {'data': sorted(data.items())})

In template file:

{% for key, value in data %}
    <tr>
        <td> Key: {{ key }} </td> 
        <td> Value: {{ value }} </td>
    </tr>
{% endfor %}

It works for me. Inject $window service in to your controller.

$window.open("somepath/", "_blank")

just change the path:

"c:\program files\android\sdk" to "c:\progra~1\android\sdk"
or
"c:\program files (x86)\android\sdk" to "c:\progra~2\android\sdk"

note that the paths should not contain spaces.

There are four ways I've found to put a newline into the minibuffer.

1. C-o

2. C-q C-j

3. C-q 12 (12 is the octal value of newline)

4. C-x o to the main window, kill a newline with C-k, then C-x o back to the minibuffer, yank it with C-y

UPDATE

The bookmarklet hack below is broken due to XHR issues and API changes.

Thankfully Github now has "A Whole New Code Search" which does the job superbly.

Checkout this voodoo: Github code search userscript.

Follow the directions there, or if you hate bloating your browser with scripts and extensions, use my bookmarkified bundle of the userscript:

javascript:(function(){var s='https://raw.githubusercontent.com/skratchdot/github-enhancement-suite/master/build/github-enhancement-suite.user.js',t='text/javascript',d=document,n=navigator,e;(e=d.createElement('script')).src=s;e.type=t;d.getElementsByTagName('head')[0].appendChild(e)})();doIt('');void('');

Save the source above as the URL of a new bookmark. Browse to any Github repo, click the bookmark, and bam: in-page, ajaxified code search.

CAVEAT Github must index a repo before you can search it.

Abracadabra...

Here's a sample search from the annotated ECMAScript 5.1 specification repository:

There is also array_replace, where an original array is modified by other arrays preserving the key => value association without creating duplicate keys.

• Same keys on other arrays will cause values to overwrite the original array
• New keys on other arrays will be created on the original array

You can try this:

: ${depth?"Error Message"} ## when your depth variable is not even declared or is unset.

NOTE: Here it's just ? after depth.

or

: ${depth:?"Error Message"} ## when your depth variable is declared but is null like: "depth=". 

NOTE: Here it's :? after depth.

Here if the variable depth is found null it will print the error message and then exit.

Your current code:

ggplot(histogram, aes(f0, fill = utt)) + geom_histogram(alpha = 0.2)

is telling ggplot to construct one histogram using all the values in f0 and then color the bars of this single histogram according to the variable utt.

What you want instead is to create three separate histograms, with alpha blending so that they are visible through each other. So you probably want to use three separate calls to geom_histogram, where each one gets it's own data frame and fill:

ggplot(histogram, aes(f0)) + 
    geom_histogram(data = lowf0, fill = "red", alpha = 0.2) + 
    geom_histogram(data = mediumf0, fill = "blue", alpha = 0.2) +
    geom_histogram(data = highf0, fill = "green", alpha = 0.2) +

Here's a concrete example with some output:

dat <- data.frame(xx = c(runif(100,20,50),runif(100,40,80),runif(100,0,30)),yy = rep(letters[1:3],each = 100))

ggplot(dat,aes(x=xx)) + 
    geom_histogram(data=subset(dat,yy == 'a'),fill = "red", alpha = 0.2) +
    geom_histogram(data=subset(dat,yy == 'b'),fill = "blue", alpha = 0.2) +
    geom_histogram(data=subset(dat,yy == 'c'),fill = "green", alpha = 0.2)

which produces something like this:

Edited to fix typos; you wanted fill, not colour.

for MySQL all (and 5.7)

SELECT LOWER(TRIM(BOTH 0x22 FROM TRIM(BOTH 0x20 FROM SUBSTRING(SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"'),LOCATE(0x2C,SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"')+1,LENGTH(json_filed)))),LOCATE(0x22,SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"'),LOCATE(0x2C,SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"')+1,LENGTH(json_filed))))),LENGTH(json_filed))))) AS result FROM `table`;

You also need to skip any hidden inputs.

for (var i = 0; document.forms[0].elements[i].type == 'hidden'; i++);
document.forms[0].elements[i].focus();

To get the date to show as the current time zone I used the following.

if let timeResult = (jsonResult["dt"] as? Double) {
     let date = NSDate(timeIntervalSince1970: timeResult)
     let dateFormatter = NSDateFormatter()
     dateFormatter.timeStyle = NSDateFormatterStyle.MediumStyle //Set time style
     dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle //Set date style
     dateFormatter.timeZone = NSTimeZone()
     let localDate = dateFormatter.stringFromDate(date)
}

Swift 3.0 Version

if let timeResult = (jsonResult["dt"] as? Double) {
    let date = Date(timeIntervalSince1970: timeResult)
    let dateFormatter = DateFormatter()
    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
    dateFormatter.timeZone = self.timeZone
    let localDate = dateFormatter.string(from: date)                     
}

Swift 5

if let timeResult = (jsonResult["dt"] as? Double) {
    let date = Date(timeIntervalSince1970: timeResult)
    let dateFormatter = DateFormatter()
    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
    dateFormatter.timeZone = .current
    let localDate = dateFormatter.string(from: date)                                
}

This is a known bug at MySQL.

bug 42996
bug 40477

As you can see this has been a known issue since 2008 and they have not fixed it yet!!!

WORK AROUND
You first need to create the database to import. It doesn't need any tables. Then you can import your database.

1. first start your MySQL command line (apply username and password if you need to)
   C:\>mysql -u user -p

2. Create your database and exit

   mysql> DROP DATABASE database;  
   mysql> CREATE DATABASE database;  
   mysql> Exit  
   

3. Import your selected database from the dump file
   C:\>mysql -u user -p -h localhost -D database -o < dumpfile.sql

You can replace localhost with an IP or domain for any MySQL server you want to import to. The reason for the DROP command in the mysql prompt is to be sure we start with an empty and clean database.

Here's an alternative since you don't like the cast to int:

foreach(byte b in System.Text.Encoding.UTF8.GetBytes(str.ToCharArray()))
    Console.Write(b.ToString());

What if you specified the default value to return, instead of using default(T)?

public static T GetQueryString<T>(string key, T defaultValue) {...}

It makes calling it easier too:

var intValue = GetQueryString("intParm", Int32.MinValue);
var strValue = GetQueryString("strParm", "");
var dtmValue = GetQueryString("dtmPatm", DateTime.Now); // eg use today's date if not specified

The downside being you need magic values to denote invalid/missing querystring values.

Reason for me is 2 of following code in one xml

<?xml version="1.0" encoding="utf-8"?>

You haven't been very specific with your code, so I'll make up a scenario. Let's say you have 10 ajax calls and you want to accumulate the results from those 10 ajax calls and then when they have all completed you want to do something. You can do it like this by accumulating the data in an array and keeping track of when the last one has finished:

Manual Counter

var ajaxCallsRemaining = 10;
var returnedData = [];

for (var i = 0; i < 10; i++) {
    doAjax(whatever, function(response) {
        // success handler from the ajax call

        // save response
        returnedData.push(response);

        // see if we're done with the last ajax call
        --ajaxCallsRemaining;
        if (ajaxCallsRemaining <= 0) {
            // all data is here now
            // look through the returnedData and do whatever processing 
            // you want on it right here
        }
    });
}

Note: error handling is important here (not shown because it's specific to how you're making your ajax calls). You will want to think about how you're going to handle the case when one ajax call never completes, either with an error or gets stuck for a long time or times out after a long time.

jQuery Promises

Adding to my answer in 2014. These days, promises are often used to solve this type of problem since jQuery's $.ajax() already returns a promise and $.when() will let you know when a group of promises are all resolved and will collect the return results for you:

var promises = [];
for (var i = 0; i < 10; i++) {
    promises.push($.ajax(...));
}
$.when.apply($, promises).then(function() {
    // returned data is in arguments[0][0], arguments[1][0], ... arguments[9][0]
    // you can process it here
}, function() {
    // error occurred
});

ES6 Standard Promises

As specified in kba's answer: if you have an environment with native promises built-in (modern browser or node.js or using babeljs transpile or using a promise polyfill), then you can use ES6-specified promises. See this table for browser support. Promises are supported in pretty much all current browsers, except IE.

If doAjax() returns a promise, then you can do this:

var promises = [];
for (var i = 0; i < 10; i++) {
    promises.push(doAjax(...));
}
Promise.all(promises).then(function() {
    // returned data is in arguments[0], arguments[1], ... arguments[n]
    // you can process it here
}, function(err) {
    // error occurred
});

If you need to make a non-promise async operation into one that returns a promise, you can "promisify" it like this:

function doAjax(...) {
    return new Promise(function(resolve, reject) {
        someAsyncOperation(..., function(err, result) {
            if (err) return reject(err);
            resolve(result);
        });
    });
}

And, then use the pattern above:

var promises = [];
for (var i = 0; i < 10; i++) {
    promises.push(doAjax(...));
}
Promise.all(promises).then(function() {
    // returned data is in arguments[0], arguments[1], ... arguments[n]
    // you can process it here
}, function(err) {
    // error occurred
});

Bluebird Promises

If you use a more feature rich library such as the Bluebird promise library, then it has some additional functions built in to make this easier:

 var doAjax = Promise.promisify(someAsync);
 var someData = [...]
 Promise.map(someData, doAjax).then(function(results) {
     // all ajax results here
 }, function(err) {
     // some error here
 });

I bumped the answer that pointed me in the right direction, but...

For those who are using Visual C++:

If you need to turn off auto-increment of the version, you can change this value in the "AssemblyInfo.cpp" file (all CLR projects have one). Give it a real version number without the asterisk and it will work the way you want it to.

Just don't forget to implement your own version-control on your assembly!

I had the same problem. After adding velocity dependencies in my maven project i was getting the same error in marker tab. Then I noticed that the web.xml file that maven project creates has servlet2.3 schema. When i changed it to servlet 3.0 schema and save the project then this error gone. Here is the web.xml file that maven creates

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>
</web-app>

Change it to

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                        version="3.0">
    <display-name>Archetype Created Web Application</display-name>

</web-app>

save the project, and your error would gone.

After that if markers tab is still showing message then Select the project. Do mouse right click. Select Maven --> Update Project.

Hopefully error would be gone then.

Thanks

None of the above works on a simple case when the page includes a call to web user control that involves IHttpHandler request processing (captcha). After sending the requsrt (for image processing) the code below does not clear the fields on the form (before sending the HttpHandler request ) everythings works correctly.

<input type="reset"  value="ClearAllFields" onclick="ClearContact()" />

 <script type="text/javascript">
       function ClearContact() {
           ("form :text").val("");
       }
    </script>

Yes, use -E -dM options instead of -c. Example (outputs them to stdout):

 gcc -dM -E - < /dev/null

For C++

 g++ -dM -E -x c++ - < /dev/null

From the gcc manual:

Instead of the normal output, generate a list of `#define' directives for all the macros defined during the execution of the preprocessor, including predefined macros. This gives you a way of finding out what is predefined in your version of the preprocessor. Assuming you have no file foo.h, the command

touch foo.h; cpp -dM foo.h

will show all the predefined macros.

If you use -dM without the -E option, -dM is interpreted as a synonym for -fdump-rtl-mach.

See the Parameter Expansion section in the Bash man page. A[@] returns the contents of the array, :1:2 takes a slice of length 2, starting at index 1.

A=( foo bar "a  b c" 42 )
B=("${A[@]:1:2}")
C=("${A[@]:1}")       # slice to the end of the array
echo "${B[@]}"        # bar a  b c
echo "${B[1]}"        # a  b c
echo "${C[@]}"        # bar a  b c 42
echo "${C[@]: -2:2}"  # a  b c 42 # The space before the - is necesssary

Note that the fact that "a b c" is one array element (and that it contains an extra space) is preserved.

SELECT SC.StoreId 
FROM StoreClients SC
WHERE SC.StoreId NOT IN (SELECT StoreId FROM StoreClients WHERE ClientId = 5)

In this way neither JOIN nor GROUP BY is necessary.

You can use one of the following methods:

document.getElementById('log').innerHTML = "text";

document.getElementById('log').innerText = "text";

document.getElementById('log').textContent = "text";

For Jquery:

$("#log").text("text");

$("#log").html("text");

Delete confirmation popup using bootstrap in angularjs

very simple.. I have one solution for this with using bootstrap conformation popup. Here i am provided

<button ng-click="deletepopup($index)">Delete</button>

in bootstrap model popup:

<div class="modal-footer">
  <a href="" data-dismiss="modal" ng-click="deleteData()">Yes</a>
  <a href="" data-dismiss="modal">No</a>
</div>

js

var index=0;
$scope.deleteData=function(){
    $scope.model.contacts.splice(index,1);
}
// delete a row 
$scope.deletepopup = function ($index) {
    index=$index;
    $('#myModal').modal('show');
};

when i click delete button bootstrap delete conformation popup will open and when i click yes button row will deleted.

I would suggest TARGET_FILE_DIR if you want the file to be copied to the same folder as your .exe file.

$ Directory of main file (.exe, .so.1.2, .a).

add_custom_command(
  TARGET ${PROJECT_NAME} POST_BUILD
  COMMAND ${CMAKE_COMMAND} -E copy 
    ${CMAKE_CURRENT_SOURCE_DIR}/input.txt 
    $<TARGET_FILE_DIR:${PROJECT_NAME}>)

In VS, this cmake script will copy input.txt to the same file as your final exe, no matter it's debug or release.

You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:

 git add a_text_file.txt 

... do:

 git commit -m "Initial commit."

... and those errors should go away.

I needed to make report for a catering firm which serves lunches for various clients. In other words, catering may have on or more firms which take orders from catering, and it must know how many lunches it must produce every single day for all it's clients !

Just to notice, I didn't use sorting, in order not to over complicate this example.

This is my code :

@Test
public void test_2() throws Exception {
    Firm catering = DS.firm().get(1);
    LocalDateTime ldtFrom = LocalDateTime.of(2017, Month.JANUARY, 1, 0, 0);
    LocalDateTime ldtTo = LocalDateTime.of(2017, Month.MAY, 2, 0, 0);
    Date dFrom = Date.from(ldtFrom.atZone(ZoneId.systemDefault()).toInstant());
    Date dTo = Date.from(ldtTo.atZone(ZoneId.systemDefault()).toInstant());

    List<PersonOrders> LON = DS.firm().getAllOrders(catering, dFrom, dTo, false);
    Map<Object, Long> M = LON.stream().collect(
            Collectors.groupingBy(p
                    -> Arrays.asList(p.getDatum(), p.getPerson().getIdfirm(), p.getIdProduct()),
                    Collectors.counting()));

    for (Map.Entry<Object, Long> e : M.entrySet()) {
        Object key = e.getKey();
        Long value = e.getValue();
        System.err.println(String.format("Client firm :%s, total: %d", key, value));

I was getting the same "cannot find symbol" error when I did Build -> Make Project. I fixed this by deleting my Maven /target folder, right clicking my project module and doing Maven -> Reimport, and doing Build -> Rebuild Project. This was on IntelliJ Idea 13.1.5.

It turns out the Maven -> Reimport was key, since the problem resurfaced a few times before I finally did that.

I did install git and tried again and got the same error. But running 'npm install' in a new command prompt window worked for me. Restarting the machine is not required.

file.lines with JFile package

Pseudo

var JFile=require('jfile');

var myF=new JFile("./data.txt");
myF.lines // ["first line","second line"] ....

Don't forget before :

npm install jfile --save

This can be changed to 0/1 through using CASE WHEN like this example:

SELECT 
 CASE WHEN SchemaName.TableName.BitFieldName = 'true' THEN 1 ELSE 0 END AS 'bit Value' 
 FROM SchemaName.TableName

You can use .addAll() to add the elements of the second list to the first:

array1.addAll(array2);

Edit: Based on your clarification above ("i want a single String in the new Arraylist which has both name and number."), you would want to loop through the first list and append the item from the second list to it.

Something like this:

int length = array1.size();
if (length != array2.size()) { // Too many names, or too many numbers
    // Fail
}
ArrayList<String> array3 = new ArrayList<String>(length); // Make a new list
for (int i = 0; i < length; i++) { // Loop through every name/phone number combo
    array3.add(array1.get(i) + " " + array2.get(i)); // Concat the two, and add it
}

If you put in:

array1 : ["a", "b", "c"]
array2 : ["1", "2", "3"]

You will get:

array3 : ["a 1", "b 2", "c 3"]

I don't think you can do that easily with the InvokeCommandAction - I would take a look at EventToCommand from MVVMLight or similar.

Yes, a destructor (a.k.a. dtor) is called when an object goes out of scope if it is on the stack or when you call delete on a pointer to an object.

1. If the pointer is deleted via delete then the dtor will be called. If you reassign the pointer without calling delete first, you will get a memory leak because the object still exists in memory somewhere. In the latter instance, the dtor is not called.

2. A good linked list implementation will call the dtor of all objects in the list when the list is being destroyed (because you either called some method to destory it or it went out of scope itself). This is implementation dependent.

3. I doubt it, but I wouldn't be surprised if there is some odd circumstance out there.

List all variables set in the config file, along with their values.

git config --list

If you are new to git then use the following commands to set a user name and email address.

Set user name

git config --global user.name "your Name"

Set user email

git config --global user.email "[email protected]"

Check user name

git config user.name

Check user email

git config user.email

The following allows for the ordering of objects by key OR by a key within an object.

In template you can do something like:

    <li ng-repeat="(k,i) in objectList | orderObjectsBy: 'someKey'">

Or even:

    <li ng-repeat="(k,i) in objectList | orderObjectsBy: 'someObj.someKey'">

The filter:

app.filter('orderObjectsBy', function(){
 return function(input, attribute) {
    if (!angular.isObject(input)) return input;

    // Filter out angular objects.
    var array = [];
    for(var objectKey in input) {
      if (typeof(input[objectKey])  === "object" && objectKey.charAt(0) !== "$")
        array.push(input[objectKey]);
    }

    var attributeChain = attribute.split(".");

    array.sort(function(a, b){

      for (var i=0; i < attributeChain.length; i++) {
        a = (typeof(a) === "object") && a.hasOwnProperty( attributeChain[i]) ? a[attributeChain[i]] : 0;
        b = (typeof(b) === "object") && b.hasOwnProperty( attributeChain[i]) ? b[attributeChain[i]] : 0;
      }

      return parseInt(a) - parseInt(b);
    });

    return array;
 }
})

for those used to php:

//add this function
function foreach(arr, func){
  for(var i in arr){
    func(i, arr[i]);
  }
}

usage:

foreach(myArray, function(i, v){
  //run code here
});

similar to php version:

foreach(myArray as i=>v){
  //run code here
}

I did a few simple tests:

In [10]: x = pd.Series(range(1000000))

In [13]: timeit 999999 in x.values
567 µs ± 25.6 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [15]: timeit x.isin([999999]).any()
9.54 ms ± 291 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

In [16]: timeit (x == 999999).any()
6.86 ms ± 107 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

In [17]: timeit 999999 in set(x)
79.8 ms ± 1.98 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

In [21]: timeit x.eq(999999).any()
7.03 ms ± 33.7 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

In [22]: timeit x.eq(9).any()
7.04 ms ± 60 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

In [24]: timeit 9 in x.values
666 µs ± 15.7 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Interestingly it doesn't matter if you look up 9 or 999999, it seems like it takes about the same amount of time using the in syntax (must be using binary search)

In [24]: timeit 9 in x.values
666 µs ± 15.7 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [25]: timeit 9999 in x.values
647 µs ± 5.21 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [26]: timeit 999999 in x.values
642 µs ± 2.11 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [27]: timeit 99199 in x.values
644 µs ± 5.31 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [28]: timeit 1 in x.values
667 µs ± 20.8 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Seems like using x.values is the fastest, but maybe there is a more elegant way in pandas?

Also note the CultureInformation of your system. Here my solution without rounding.

In this example you just have to define the variable MyValue as double. As result you get your formatted value in the string variable NewValue.

Note - Also set the C# using statement:

using System.Globalization;  

string MyFormat = "0";
if (MyValue.ToString (CultureInfo.InvariantCulture).Contains (CultureInfo.InvariantCulture.NumberFormat.NumberDecimalSeparator))
   {
      MyFormat += ".00";
   }

string NewValue = MyValue.ToString(MyFormat);

This issue is caused by the URL bars shrinking/sliding out of the way and changing the size of the #bg1 and #bg2 divs since they are 100% height and "fixed". Since the background image is set to "cover" it will adjust the image size/position as the containing area is larger.

Based on the responsive nature of the site, the background must scale. I entertain two possible solutions:

1) Set the #bg1, #bg2 height to 100vh. In theory, this an elegant solution. However, iOS has a vh bug (http://thatemil.com/blog/2013/06/13/viewport-relative-unit-strangeness-in-ios-6/). I attempted using a max-height to prevent the issue, but it remained.

2) The viewport size, when determined by Javascript, is not affected by the URL bar. Therefore, Javascript can be used to set a static height on the #bg1 and #bg2 based on the viewport size. This is not the best solution as it isn't pure CSS and there is a slight image jump on page load. However, it is the only viable solution I see considering iOS's "vh" bugs (which do not appear to be fixed in iOS 7).

var bg = $("#bg1, #bg2");

function resizeBackground() {
    bg.height($(window).height());
}

$(window).resize(resizeBackground);
resizeBackground();

On a side note, I've seen so many issues with these resizing URL bars in iOS and Android. I understand the purpose, but they really need to think through the strange functionality and havoc they bring to websites. The latest change, is you can no longer "hide" the URL bar on page load on iOS or Chrome using scroll tricks.

EDIT: While the above script works perfectly for keeping the background from resizing, it causes a noticeable gap when users scroll down. This is because it is keeping the background sized to 100% of the screen height minus the URL bar. If we add 60px to the height, as swiss suggests, this problem goes away. It does mean we don't get to see the bottom 60px of the background image when the URL bar is present, but it prevents users from ever seeing a gap.

function resizeBackground() {
    bg.height( $(window).height() + 60);
}

I was in a situation where we have a master branch, and then another branch called 17.0 and inside this 17.0 there was a commit hash no say "XYZ". And customer is given a build till that XYZ revision. Now we came across a bug and that needs to be solved for that customer. So we need to create separate branch for that customer till that "xyz" hash. So here is how I did it.

First I created a folder with that customer name on my local machine. Say customer name is "AAA" once that folder is created issue following command inside this folder:

1. git init
2. git clone After this command you will be on master branch. So switch to desired branch
3. git checkout 17.0 This will bring you to the branch where your commit is present
4. git checkout This will take your repository till that hash commit. See the name of ur branch it got changed to that commit hash no. Now give a branch name to this hash
5. git branch ABC This will create a new branch on your local machine.
6. git checkout ABC
7. git push origin ABC This will push this branch to remote repository and create a branch on git server. You are done.

As far as I can tell, you don't necessarily need to specify the axis when using the filter function.

new = old.filter(['A','B','D'])

returns the same dataframe as

new = old.filter(['A','B','D'], axis=1)

This is working for me

Podfile:

platform :ios, '9.0'
use_frameworks!

target '<Your Target Name>' do
pod 'SwiftGifOrigin', '~> 1.7.0'
end

Usage:

// An animated UIImage
let jeremyGif = UIImage.gif(name: "jeremy")

// A UIImageView with async loading
let imageView = UIImageView()
imageView.loadGif(name: "jeremy")

// A UIImageView with async loading from asset catalog(from iOS9)
let imageView = UIImageView()
imageView.loadGif(asset: "jeremy")

I had also the same problem once. There is no way to access directly the file within android devices except adb shell or rooting device.

Beside here are 02 alternatives:

1)

 public void exportDatabse(String databaseName)
   {
     try {
        File sd = Environment.getExternalStorageDirectory();
        File data = Environment.getDataDirectory();

        if (sd.canWrite()) {
            String currentDBPath = "//data//"+getPackageName()+"//databases//"+databaseName+"";
            String backupDBPath = "backupname.db";
            File currentDB = new File(data, currentDBPath);
            File backupDB = new File(sd, backupDBPath);

            if (currentDB.exists()) {
                FileChannel src = new FileInputStream(currentDB).getChannel();
                FileChannel dst = new FileOutputStream(backupDB).getChannel();
                dst.transferFrom(src, 0, src.size());
                src.close();
                dst.close();
            }
        }
    } catch (Exception e) {

    }
}

2) Try this: https://github.com/sanathp/DatabaseManager_For_Android

In case you have to replace multiple values and if you don't mind "refactoring" your variable with as.factor(as.character(...)) you could try the following:

replace.values <- function(search, replace, x){
  stopifnot(length(search) == length(replace))
  xnew <- replace[ match(x, search) ]
  takeOld <- is.na(xnew) & !is.na(x)
  xnew[takeOld] <- x[takeOld]
  return(xnew)
}

iris$Species <- as.factor(search=c("oldValue1","oldValue2"),
                          replace=c("newValue1","newValue2"),
                          x=as.character(iris$Species))

There are better ways to do this as explained by other posters. But if I want to stick to pure JS and ol' fashioned way then here it is:

var arr = [
    { key: 'foo', val: 'bar' },
    { key: 'hello', val: 'world' },
    { key: 'hello', val: 'universe' }
];

var map = {};
for (var i = 0; i < arr.length; i++) {
    var key = arr[i].key;
    var value = arr[i].val;

    if (key in map) {
        map[key].push(value);
    } else {
        map[key] = [value];
    }
}

console.log(map);

When I've done this, rather than fiddling the original migration, I create a new one with just the add column in the up section and a drop column in the down section.

You can change the original and rerun it if you migrate down between, but in this case I think that's made a migration that won't work properly.

As currently posted, you're adding the column and then creating the table.

If you change the order it might work. Or, as you're modifying an existing migration, just add it to the create table instead of doing a separate add column.

Short answer

You can see the full table of percentages to hex values and run the code in this playground in https://play.golang.org/p/l1JaPYFzDkI .

Short explanation in pseudocode

Percentage to hex values

1. decimal = percentage * 255 / 100 . ex : decimal = 50*255/100 = 127.5
2. convert decimal to hexadecimal value . ex: 127.5 in decimal = 7*16ˆ1 + 15 = 7F in hexadecimal

Hex values to percentage

1. convert the hexaxdecimal value to decimal. ex: D6 = 13*16ˆ1 + 6 = 214
2. percentage = (value in decimal ) * 100 / 255. ex : 214 *100/255 = 84%

More infos for the conversion decimal <=> hexadecimal

Long answer: how to calculate in your head

The problem can be solved generically by a cross multiplication.

We have a percentage (ranging from 0 to 100 ) and another number (ranging from 0 to 255) then converted to hexadecimal.

• 100 <==> 255 (FF in hexadecimal)
• 0 <==> 0 (00 in hexadecimal)

For 1%

• 1 * 255 / 100 = 2,5
• 2,5 in hexa is 2 if you round it down.

For 2%

• 2 * 255 / 100 = 5
• 5 in hexa is 5 .

The table in the best answer gives the percentage by step of 5%.

How to calculate the numbers between in your head ? Due to the 2.5 increment, add 2 to the first and 3 to the next

• 95% — F2 // start
• 96% — F4 // add 2 to F2
• 97% — F7 // add 3 . Or F2 + 5 = F7
• 98% — F9 // add 2
• 99% — FC // add 3. 9 + 3 = 12 in hexa : C
• 100% — FF // add 2

I prefer to teach how to find the solution rather than showing an answer table you don't know where the results come from.

To update NPM, this worked for me:

• Navigate in your shell to your node installation directory, eg C:\Program Files (x86)\nodejs
• run npm install npm (no -g option)

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

Why Server.Transfer? Response.Redirect(Request.RawUrl) would get you what you need.

Add a random query string to the src

You could either do this manually by incrementing the querystring each time you make a change:

<script src="test.js?version=1"></script>

Or if you are using a server side language, you could automatically generate this:

ASP.NET:

<script src="test.js?rndstr=<%= getRandomStr() %>"></script>

More info on cache-busting can be found here:

https://curtistimson.co.uk/post/front-end-dev/what-is-cache-busting/

Refer to the "undo" and "redo" part of Vim document.

:red[o] (Redo one change which was undone) and {count} Ctrl+r (Redo {count} changes which were undone) are both ok.

Also, the :earlier {count} (go to older text state {count} times) could always be a substitute for undo and redo.

Get rid of the escape characters before storing or manipulating the raw string:

You could change any backslashes of the path '\' to forward slashes '/' before storing them in a variable. The forward slashes don't need to be escaped:

>>> mypath = os.getcwd().replace('\\','/')  
>>> os.path.exists(mypath)  
True  
>>>   

string [] temp = new string[] {"1","2","3"};
List<string> temp2 = temp.ToList();

Can't. Interfaces don't exist at runtime.

workaround

Create a variable of the type and use Object.keys on it

In case you run into this: in my case I had a translated string, but the string did not yet appear in the default strings.xml. Added the missing string to strings.xml and it got resolved.
