For links generated in a JSP with custom tags, I had to use

<%@ page session="false" %>

in the JSP

AND

request.getSession().invalidate();

in the Struts action

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

Your .mobile div has the following styles on it:

.mobile {
    display: none !important;
    visibility: hidden !important;
}

Therefore you need to override the visibility property with visible in addition to overriding the display property with block. Like so:

.visible-sm {
    display: block !important;
    visibility: visible !important;
}

Check out the class java.util.Formatter.

Here is a function I wrote to accomplish this based off of the previous answers.

CREATE FUNCTION dbo.RepetitiveReplace
(
    @P_String VARCHAR(MAX),
    @P_Pattern VARCHAR(MAX),
    @P_ReplaceString VARCHAR(MAX),
    @P_ReplaceLength INT = 1
)
RETURNS VARCHAR(MAX)
BEGIN
    DECLARE @Index INT;

    -- Get starting point of pattern
    SET @Index = PATINDEX(@P_Pattern, @P_String);

    while @Index > 0
    begin
        --replace matching charactger at index
        SET @P_String = STUFF(@P_String, PATINDEX(@P_Pattern, @P_String), @P_ReplaceLength, @P_ReplaceString);
        SET @Index = PATINDEX(@P_Pattern, @P_String);
    end

    RETURN @P_String;
END;

Edit:

Originally I had a recursive function here which does not play well with sql server as it has a 32 nesting level limit which would result in an error like the below any time you attempt to make 32+ replacements with the function. Instead of trying to make a server level change to allow more nesting (which could be dangerous like allow never ending loops) switching to a while loop makes a lot more sense.

Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32).

#pragma once does have one drawback (other than being non-standard) and that is if you have the same file in different locations (we have this because our build system copies files around) then the compiler will think these are different files.

I ran into an article that illustrates a method where the data from the same excel sheet can be imported in the selected table until there is no modifications in excel with data types.

If the data is inserted or overwritten with new ones, importing process will be successfully accomplished, and the data will be added to the table in SQL database.

The article may be found here: http://www.sqlshack.com/using-ssis-packages-import-ms-excel-data-database/

Hope it helps.

There's are multiple ways to split a string :

1. If you want to make it temporary then split like this:

_

import net package

host, port, err := net.SplitHostPort("0.0.0.1:8080")
if err != nil {
fmt.Println("Error is splitting : "+err.error());
//do you code here
}
fmt.Println(host, port)

2. Split based on struct :

   • Create a struct and split like this

_

type ServerDetail struct {
    Host       string
    Port       string
    err        error
}

ServerDetail = net.SplitHostPort("0.0.0.1:8080") //Specific for Host and Port

Now use in you code like ServerDetail.Host and ServerDetail.Port

If you don't want to split specific string do it like this:

type ServerDetail struct {
    Host       string
    Port       string
}

ServerDetail = strings.Split([Your_String], ":") // Common split method

and use like ServerDetail.Host and ServerDetail.Port.

That's All.

For me, with the upgrade to 4.3.1, I just truncate the EdmMetaData table or just delete it outright.

This is a subjective opinion, but I think a text editor shouldn't do everything and the kitchen sink. I prefer lightweight flexible and powerful (in their specialized fields) editors. Although being mostly a Windows user, I like the Unix philosophy of having lot of specialized tools that you can pipe together (like the UnxUtils) rather than a monster doing everything, but not necessarily as you would like it!

Find in files is on the border of these extra features, but useful when you can double-click on a found line to open the file at the right line. Note that initially, in SciTE it was just a Tools call to grep or equivalent!
FTP is very close to off topic, although it can be seen as an extended open/save dialog.
Replace in files is too much IMO: it is dangerous (you can mess lot of files at once) if you have no preview, etc. I would rather use a specialized tool I chose, perhaps among those in Multi line search and replace tool.

To answer the question, looking at N++, I see a Run menu where you can launch any tool, with assignment of a name and shortcut key. I see also Plugins > NppExec, which seems able to launch stuff like sed (not tried it).

You and your friend both use closures:

A closure is a special kind of object that combines two things: a function, and the environment in which that function was created. The environment consists of any local variables that were in-scope at the time that the closure was created.

MDN: https://developer.mozilla.org/en-US/docs/JavaScript/Guide/Closures

In your friend's code function function(){ console.log(i2); } defined inside closure of anonymous function function(){ var i2 = i; ... and can read/write local variable i2.

In your code function function(){ console.log(i2); } defined inside closure of function function(i2){ return ... and can read/write local valuable i2 (declared in this case as a parameter).

In both cases function function(){ console.log(i2); } then passed into setTimeout.

Another equivalent (but with less memory utilization) is:

function fGenerator(i2){
    return function(){
        console.log(i2);
    }
}
for(var i = 0; i < 10; i++) {
    setTimeout(fGenerator(i), 1000);
}

>> npm uninstall -g angular-cli
>> npm uninstall -g @angular/cli

>> npm cache clean

Restart you machine

then >> npm install -g @angular/cli@latest

You can set position of image is align center horizontal by this

With a report (rdl) file selected in your solution, select View and then Report Data.

It is a shortcut of Ctrl+Alt+D.

Because that syntax simply isn't defined? Besides, x < y evaluates as a bool, so what does bool < int mean? It isn't really an overhead; besides, you could write a utility method if you really want - isBetween(10,x,20) - I wouldn't myself, but hey...

If you've installed flutter from the snap store on Ubuntu, you'll find the SDK at /home/(username)/snap/flutter/common/flutter

FYI - I installed Flutter on Ubuntu 20.04 LTS using snap install and am using Android Studio 4.0.1 installed via JetBrains toolbox app

sudo snap install flutter --classic
sudo snap install flutter-gallery
flutter channel dev
flutter upgrade
flutter config --enable-linux-desktop

It was not necessary to install the SDK separately, the snap steps above will place the SDK at /home/(username)/snap/flutter/common/flutter

Here's the Android Studio Pop-up for a new Flutter app accepting this location for the Flutter SDK:

Use File.AppendAllText instead:

File.AppendAllText(filePath + "log.txt", log);

If you are wanting to configure this locally on OS X 10.8 serving Angular with Apache then you might find the following in your .htaccess file helps:

<IfModule mod_rewrite.c>
    Options +FollowSymlinks
    RewriteEngine On
    RewriteBase /~yourusername/appname/public/
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !.*\.(css|js|html|png|jpg|jpeg|gif|txt)
    RewriteRule (.*) index.html [L]
</IfModule>

Options +FollowSymlinks if not set may give you a forbidden error in the logs like so:

Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden

Rewrite base is required otherwise requests will be resolved to your server root which locally by default is not your project directory unless you have specifically configured your vhosts, so you need to set the path so that the request finds your project root directory. For example on my machine I have a /Users/me/Sites directory where I keep all my projects. Like the old OS X set up.

The next two lines effectively say if the path is not a directory or a file, so you need to make sure you have no files or directories the same as your app route paths.

The next condition says if request not ending with file extensions specified so add what you need there

And the [L] last one is saying to serve the index.html file - your app for all other requests.

If you still have problems then check the apache log, it will probably give you useful hints:

/private/var/log/apache2/error_log

Store it anywhere in an accessible location except of the IDE's project folder aka the server's deploy folder, for reasons mentioned in the answer to Uploaded image only available after refreshing the page:

1. Changes in the IDE's project folder does not immediately get reflected in the server's work folder. There's kind of a background job in the IDE which takes care that the server's work folder get synced with last updates (this is in IDE terms called "publishing"). This is the main cause of the problem you're seeing.

2. In real world code there are circumstances where storing uploaded files in the webapp's deploy folder will not work at all. Some servers do (either by default or by configuration) not expand the deployed WAR file into the local disk file system, but instead fully in the memory. You can't create new files in the memory without basically editing the deployed WAR file and redeploying it.

3. Even when the server expands the deployed WAR file into the local disk file system, all newly created files will get lost on a redeploy or even a simple restart, simply because those new files are not part of the original WAR file.

It really doesn't matter to me or anyone else where exactly on the local disk file system it will be saved, as long as you do not ever use getRealPath() method. Using that method is in any case alarming.

The path to the storage location can in turn be definied in many ways. You have to do it all by yourself. Perhaps this is where your confusion is caused because you somehow expected that the server does that all automagically. Please note that @MultipartConfig(location) does not specify the final upload destination, but the temporary storage location for the case file size exceeds memory storage threshold.

So, the path to the final storage location can be definied in either of the following ways:

• Hardcoded:

    File uploads = new File("/path/to/uploads");
  

• Environment variable via SET UPLOAD_LOCATION=/path/to/uploads:

    File uploads = new File(System.getenv("UPLOAD_LOCATION"));
  

• VM argument during server startup via -Dupload.location="/path/to/uploads":

    File uploads = new File(System.getProperty("upload.location"));
  

• *.properties file entry as upload.location=/path/to/uploads:

    File uploads = new File(properties.getProperty("upload.location"));
  

• web.xml <context-param> with name upload.location and value /path/to/uploads:

    File uploads = new File(getServletContext().getInitParameter("upload.location"));
  

• If any, use the server-provided location, e.g. in JBoss AS/WildFly:

    File uploads = new File(System.getProperty("jboss.server.data.dir"), "uploads");
  

Either way, you can easily reference and save the file as follows:

File file = new File(uploads, "somefilename.ext");

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath());
}

Or, when you want to autogenerate an unique file name to prevent users from overwriting existing files with coincidentally the same name:

File file = File.createTempFile("somefilename-", ".ext", uploads);

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath(), StandardCopyOption.REPLACE_EXISTING);
}

How to obtain part in JSP/Servlet is answered in How to upload files to server using JSP/Servlet? and how to obtain part in JSF is answered in How to upload file using JSF 2.2 <h:inputFile>? Where is the saved File?

Note: do not use Part#write() as it interprets the path relative to the temporary storage location defined in @MultipartConfig(location).

If you want to write portable C++ code, then I'd suggest using cin.get().

system("PAUSE") works on Windows, since it requires the execution of a console command named "PAUSE". But I'm not sure that other operating systems like Linux or other Unix derivatives support that. So that tends to be non-portable.

Since C++ already offers cin.get(), I see no compelling reason to use C getch().

I found solution. The call:

-(void) someMethod{
    UIButton * but;
    but.tag = 1;//some id button that you choice 
    [but addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside]; 
}

And here the method called:

-(void) buttonPressed : (id) sender{
    UIButton *clicked = (UIButton *) sender;
    NSLog(@"%d",clicked.tag);//Here you know which button has pressed
}

window.open ("http://www.javascript-coder.com",
"mywindow","menubar=1,resizable=1,width=350,height=250");

Prepending the Linux command timeout isn't a bad workaround and it worked for me.

cmd = "timeout 20 "+ cmd
subprocess.Popen(cmd.split(), stdout=subprocess.PIPE, stderr=subprocess.PIPE)
(output, err) = p.communicate()

I think "disabled" excludes the input from being sent on the POST

Per Microsoft in powershell:

Found this on HTML table: keep the same width for columns

If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your to and remove the inside of it, and then set fixed widths for the cells in .

Here's a simple, working example:

package main

import (
    "io"
    "net/http"
)
func queryParamDisplayHandler(res http.ResponseWriter, req *http.Request) {
    io.WriteString(res, "name: "+req.FormValue("name"))
    io.WriteString(res, "\nphone: "+req.FormValue("phone"))
}

func main() {
    http.HandleFunc("/example", func(res http.ResponseWriter, req *http.Request) {
        queryParamDisplayHandler(res, req)
    })
    println("Enter this in your browser:  http://localhost:8080/example?name=jenny&phone=867-5309")
    http.ListenAndServe(":8080", nil)
}

For someone from internet, there was a similar question https://stackoverflow.com/a/35848666/906265 I do provide the modified answer from it here as well:

// build.gradle
<...>

bootRun {}

// make sure bootRun is executed when this task runs
task runDev(dependsOn:bootRun) {
    // TaskExecutionGraph is populated only after 
    // all the projects in the build have been evaulated https://docs.gradle.org/current/javadoc/org/gradle/api/execution/TaskExecutionGraph.html#whenReady-groovy.lang.Closure-
    gradle.taskGraph.whenReady { graph ->
        logger.lifecycle('>>> Setting spring.profiles.active to dev')
        if (graph.hasTask(runDev)) {
            // configure task before it is executed
            bootRun {
                args = ["--spring.profiles.active=dev"]
            }
        }
    }
}

<...>

then in terminal:

gradle runDev

Have used gradle 3.4.1 and spring boot 1.5.10.RELEASE

CMake 3.13 on Ubuntu 16.04

This approach is more flexible because it doesn't constraint MY_VARIABLE to a type:

    message("MY_VARIABLE evaluates to True")
endif()

Here is a CSV action result I wrote that takes a DataTable and converts it into CSV. You can return this from your view and it will prompt the user to download the file. You should be able to convert this easily into a List compatible form or even just put your list into a DataTable.

            response.Write(csv.ToString());
        }

        protected string CleanCSVString(string input)
        {
            string output = "\"" + input.Replace("\"", "\"\"").Replace("\r\n", " ").Replace("\r", " ").Replace("\n", "") + "\"";
            return output;

You can look up the constraint name in the sys.key_constraints table:

SELECT name
FROM   sys.key_constraints
WHERE  [type] = 'PK'
       AND [parent_object_id] = Object_id('dbo.Student');

If you don't care about the name, but simply want to drop it, you can use a combination of this and dynamic sql:

DECLARE @table NVARCHAR(512), @sql NVARCHAR(MAX);

SELECT @table = N'dbo.Student';

SELECT @sql = 'ALTER TABLE ' + @table 
    + ' DROP CONSTRAINT ' + name + ';'
    FROM sys.key_constraints
    WHERE [type] = 'PK'
    AND [parent_object_id] = OBJECT_ID(@table);

EXEC sp_executeSQL @sql;

This code is from Aaron Bertrand (source).

What is the underlying logic you want to implement? If, for instance, you want to test for the existence of a record to determine to insert or update then a better choice would be to use MERGE instead.

If you expect the record to exist most of the time, this is probably the most efficient way of doing things (although the CASE WHEN EXISTS solution is likely to be just as efficient):

begin
    select null into dummy
    from sales
    where sales_type = 'Accessories'
    and rownum = 1;

    --  do things here when record exists
    ....        

exception
    when no_data_found then
        -- do things here when record doesn't exists
        .....
end;

You only need the ROWNUM line if SALES_TYPE is not unique. There's no point in doing a count when all you want to know is whether at least one record exists.

Use SAJAX or switch to JavaScript

Sajax is an open source tool to make programming websites using the Ajax framework — also known as XMLHTTPRequest or remote scripting — as easy as possible. Sajax makes it easy to call PHP, Perl or Python functions from your webpages via JavaScript without performing a browser refresh.

In your own answer, you effectively do this:

Dim SrcRange As Range ' you should always declare things explicitly
Set SrcRange = Sheets("Src").Range("A2:A9")
SrcRange.Copy Destination:=Sheets("Dest").Range("A2")

You're not really "extracting" the range to a variable, you're setting a reference to the range.

In many situations, this can be more efficient as well as more flexible:

Dim Src As Variant
Src= Sheets("Src").Range("A2:A9").Value 'Read range to array
'Here you can add code to manipulate your Src array
'...
Sheets("Dest").Range("A2:A9").Value = Src 'Write array back to another range

inside the Android manifest file of your project, find the activity declaration of whose you want to fix the orientation and add the following piece of code ,

android:screenOrientation="landscape"

for landscape orientation and for portrait add the following code,

android:screenOrientation="portrait"

One way to look at it is that the visitor pattern is a way of letting your clients add additional methods to all of your classes in a particular class hierarchy.

It is useful when you have a fairly stable class hierarchy, but you have changing requirements of what needs to be done with that hierarchy.

The classic example is for compilers and the like. An Abstract Syntax Tree (AST) can accurately define the structure of the programming language, but the operations you might want to do on the AST will change as your project advances: code-generators, pretty-printers, debuggers, complexity metrics analysis.

Without the Visitor Pattern, every time a developer wanted to add a new feature, they would need to add that method to every feature in the base class. This is particularly hard when the base classes appear in a separate library, or are produced by a separate team.

(I have heard it argued that the Visitor pattern is in conflict with good OO practices, because it moves the operations of the data away from the data. The Visitor pattern is useful in precisely the situation that the normal OO practices fail.)

import numpy as np
import pandas as pd
import scipy.sparse as sparse

df = pd.DataFrame(np.arange(1,10).reshape(3,3))
arr = sparse.coo_matrix(([1,1,1], ([0,1,2], [1,2,0])), shape=(3,3))
df['newcol'] = arr.toarray().tolist()
print(df)

yields

   0  1  2     newcol
0  1  2  3  [0, 1, 0]
1  4  5  6  [0, 0, 1]
2  7  8  9  [1, 0, 0]

I think most people want their placeholder text to be in grey and appear only once, so this is what I did:

1. Set your color in viewDidLoad() (not in IB)

   commentsTextView.textColor = UIColor.darkGray
   

2. Implement UITextViewDelegate to your controller

3. add function to your controller

   func textViewDidBeginEditing(_ textView: UITextView) {
       if (commentsTextView.textColor == UIColor.darkGray) {
          commentsTextView.text = ""
          commentsTextView.textColor = UIColor.black
       }
   }
   

This solution is simple.

To complete the list of possible alternatives, reduce could be used to implement the behavior of flatten:

The best alternative (performance/memory-wise) among the ones presented is simply flatten, that just wrap the original arrays lazily without creating a new array structure.

But notice that flatten does not return a LazyCollection, so that lazy behavior will not be propagated to the next operation along the chain (map, flatMap, filter, etc...).

If lazyness makes sense in your particular case, just remember to prepend or append a .lazy to flatten(), for example, modifying Tomasz sample this way:

let c = [a, b].lazy.flatten()

a {
    outline: 0;
  }

But read this before change it:

MariaDB supports System Versioning since 10.3 which is the standard SQL feature that does exactly what you want: it stores history of table records and provides access to it via SELECT queries. MariaDB is an open-development fork of MySQL. You can find more on its System Versioning via this link:

https://mariadb.com/kb/en/library/system-versioned-tables/

This is the full static method, which you can adapt to set waiting time and error code when IOException happens:

  public static int getResponseCode(String address) {
    return getResponseCode(address, 404);
  }

  public static int getResponseCode(String address, int defaultValue) {
    try {
      //Logger.getLogger(WebOperations.class.getName()).info("Fetching response code at " + address);
      URL url = new URL(address);
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();
      connection.setConnectTimeout(1000 * 5); //wait 5 seconds the most
      connection.setReadTimeout(1000 * 5);
      connection.setRequestProperty("User-Agent", "Your Robot Name");
      int responseCode = connection.getResponseCode();
      connection.disconnect();
      return responseCode;
    } catch (IOException ex) {
      Logger.getLogger(WebOperations.class.getName()).log(Level.INFO, "Exception at {0} {1}", new Object[]{address, ex.toString()});
      return defaultValue;
    }
  }

I don't understand the first two answers. I think they must be version-dependent. I cannot reproduce them on MySQLdb 1.2.3, which comes with Ubuntu 14.04LTS. Let's try them. First, we verify that MySQL doesn't accept double-apostrophes:

mysql> select * from methods limit 1;
+----------+--------------------+------------+
| MethodID | MethodDescription  | MethodLink |
+----------+--------------------+------------+
|       32 | Autonomous Sensing | NULL       |
+----------+--------------------+------------+
1 row in set (0.01 sec)

mysql> select * from methods where MethodID = ''32'';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '9999'' ' at line 1

Nope. Let's try the example that Mandatory posted using the query constructor inside /usr/lib/python2.7/dist-packages/MySQLdb/cursors.py where I opened "con" as a connection to my database.

>>> search = "test"
>>> "SELECT * FROM records WHERE email LIKE '%s'" % con.literal(search)
"SELECT * FROM records WHERE email LIKE ''test''"
>>> 

Nope, the double apostrophes cause it to fail. Let's try Mike Graham's first comment, where he suggests leaving off the apostrophes quoting the %s:

>>> "SELECT * FROM records WHERE email LIKE %s" % con.literal(search)
"SELECT * FROM records WHERE email LIKE 'test'"
>>> 

Yep, that will work, but Mike's second comment and the documentation says that the argument to execute (processed by con.literal) must be a tuple (search,) or a list [search]. You can try them, but you'll find no difference from the output above.

The best answer is ksg97031's.

Summary:

• @HostBinding: This decorator binds a class property to a property of the host element.
• @HostListener: This decorator binds a class method to an event of the host element.

Example:

import { Component, HostListener, HostBinding } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `<p>This is nice text<p>`,
})
export class AppComponent  {

  @HostBinding('style.color') color; 

  @HostListener('click')
  onclick() {
    this.color =  'blue';
  }

}

In the above example the following occurs:

• An event listener is added to the click event which will be fired when a click event occurs anywhere within the component
• The color property in our AppComponent class is bound to the style.color property on the component. So whenever the color property is updated so will the style.color property of our component
• The result will be that whenever someone clicks on the component the color will be updated.

Usage in @Directive:

Although it can be used on component these decorators are often used in a attribute directives. When used in an @Directive the host changes the element on which the directive is placed. For example take a look at this component template:

<p p_Dir>some paragraph</p>

Here p_Dir is a directive on the <p> element. When @HostBinding or @HostListener is used within the directive class the host will now refer to the <p>.

int *p=(int *)0x1234 = 10; //0x1234 is the memory address and value 10 is assigned in that address


unsigned int *ptr=(unsigned int *)0x903jf = 20;//0x903j is memory address and value 20 is assigned 

Basically in Embedded platform we are using directly addresses instead of names

Actually there is no any cancel() or dismiss() method from AlertDialog.Builder Class.

So Instead of AlertDialog.Builder optionDialog use AlertDialog instance.

Like,

AlertDialog optionDialog = new AlertDialog.Builder(this).create();

Now, Just call optionDialog.dismiss();

background.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        SetBackground();
        // here I want to dismiss it after SetBackground() method 
        optionDialog.dismiss();
    }
});

My simplest solution is based on fixed columns layout. You'll have to set the width of each column, for example: 4 columns 100px each is equal to 400px total width.

table {
  table-layout: fixed;
  width: 400px;
}
td, th {
  width: 100px;
}

The fixed table layout algorithm has many advantages over the automatic table layout algorithm (for example: the horizontal layout only depends on the table's width and the width of the columns, not the contents of the cells; allows a browser to lay out the table faster than the automatic table layout; the browser can begin to display the table once the first row has been received; etc.)

Then, you'll have to separate the thead from the tbody by forcing their display style to block rather than to the default table-*

thead tr {
  display: block;
}
tbody {
  display: block;
  height: 256px;
  overflow-y: auto;
}

That what will make the tbody scrollable as a separate box and the thead unrelated from it. And that's the main reason why you had to fix the column widths as done above.

I suggest code bellow. You may work with exception, when convert error occured.

public static class Utils {      
public static bool TryParse<Tin, Tout>(this Tin obj, Func<Tin, Tout> onConvert, Action<Tout> onFill, Action<Exception> onError) {
  Tout value = default(Tout);
  bool ret = true;
  try {
    value = onConvert(obj);
  }
  catch (Exception exc) {
    onError(exc);
    ret = false;
  }
  if (ret)
    onFill(value);
  return ret;
}

public static bool TryParse(this string str, Action<int?> onFill, Action<Exception> onError) {
  return Utils.TryParse(str
    , s => string.IsNullOrEmpty(s) ? null : (int?)int.Parse(s)
    , onFill
    , onError);
}
public static bool TryParse(this string str, Action<int> onFill, Action<Exception> onError) {
  return Utils.TryParse(str
    , s => int.Parse(s)
    , onFill
    , onError);
}
}

Use this extension method in code (fill int? Age property of a person class):

string ageStr = AgeTextBox.Text;
Utils.TryParse(ageStr, i => person.Age = i, exc => { MessageBox.Show(exc.Message); });

OR

AgeTextBox.Text.TryParse(i => person.Age = i, exc => { MessageBox.Show(exc.Message); });

func getTime() -> (hour: Int, minute: Int,second: Int) {
        let hour = 1
        let minute = 20
        let second = 55
        return (hour, minute, second)
    }

To use :

let(hour, min,sec) = self.getTime()
print(hour,min,sec)

<a class="navbar-brand" href="#" style="padding:0px;">
  <img src="mylogo.png" style="height:100%;">

<a class="navbar-brand" href="#" style="padding:0px;">
  <img src="mylogo.png" style="height:100%;display:inline-block;"><span>text</span>
</a>

An alternative method is to use a Gulp plugin created specifically for this problem. https://www.npmjs.com/package/gulp-ng-module-sort

It allows you to sort your scripts by adding in a .pipe(ngModuleSort()) as such:

var ngModuleSort = require('gulp-ng-module-sort');
var concat = require('gulp-concat');

gulp.task('angular-scripts', function() {
    return gulp.src('./src/app/**/*.js')
        .pipe(ngModuleSort())
        .pipe(concat('angularAppScripts.js))
        .pipe(gulp.dest('./dist/));
});

Assuming a directory convention of:

|——— src/
|   |——— app/
|       |——— module1/
|           |——— sub-module1/
|               |——— sub-module1.js
|           |——— module1.js
|       |——— module2/
|           |——— sub-module2/
|               |——— sub-module2.js
|           |——— sub-module3/
|               |——— sub-module3.js
|           |——— module2.js
|   |——— app.js

Hope this helps!

If your grep -i does not work then try using tr command to convert the the output of your file to lower case and then pipe it into standard grep with whatever you are looking for. (it sounds complicated but the actual command which I have provided for you is not !).

Notice the tr command does not change the content of your original file, it just converts it just before it feeds it into grep.

1.here is how you can do this on a file

tr '[:upper:]' '[:lower:]' <your_file.txt|grep what_ever_you_are_searching_in_lower_case

2.or in your case if you are just echoing something

echo "ABC"|tr '[:upper:]' '[:lower:]' | grep abc

multipart/form-data encoded requests are indeed not by default supported by the Servlet API prior to version 3.0. The Servlet API parses the parameters by default using application/x-www-form-urlencoded encoding. When using a different encoding, the request.getParameter() calls will all return null. When you're already on Servlet 3.0 (Glassfish 3, Tomcat 7, etc), then you can use HttpServletRequest#getParts() instead. Also see this blog for extended examples.

Prior to Servlet 3.0, a de facto standard to parse multipart/form-data requests would be using Apache Commons FileUpload. Just carefully read its User Guide and Frequently Asked Questions sections to learn how to use it. I've posted an answer with a code example before here (it also contains an example targeting Servlet 3.0).

Simple use this to strip the text :

echo strlen($string) >= 500 ? 
substr($string, 0, 490) . ' <a href="link/to/the/entire/text.htm">[Read more]</a>' : 
$string;

Edit and finally :

function split_words($string, $nb_caracs, $separator){
    $string = strip_tags(html_entity_decode($string));
    if( strlen($string) <= $nb_caracs ){
        $final_string = $string;
    } else {
        $final_string = "";
        $words = explode(" ", $string);
        foreach( $words as $value ){
            if( strlen($final_string . " " . $value) < $nb_caracs ){
                if( !empty($final_string) ) $final_string .= " ";
                $final_string .= $value;
            } else {
                break;
            }
        }
        $final_string .= $separator;
    }
    return $final_string;
}

Here separator is the href link to read more ;)

As you probably know, the maximum request length is configured in TWO places.

1. maxRequestLength - controlled at the ASP.NET app level
2. maxAllowedContentLength - under <system.webServer>, controlled at the IIS level

The first case is covered by other answers to this question.

To catch THE SECOND ONE you need to do this in global.asax:

protected void Application_EndRequest(object sender, EventArgs e)
{
    //check for the "file is too big" exception if thrown at the IIS level
    if (Response.StatusCode == 404 && Response.SubStatusCode == 13)
    {
        Response.Write("Too big a file"); //just an example
        Response.End();
    }
}

Couple of typos:

while((c = getchar())!= EOF)

in place of:

while((c = getchar() != EOF))

Also getchar() treats a return key as a valid input, so you need to buffer it too.EOF is a marker to indicate end of input. Generally it is an int with all bits set.

#include <stdio.h>
int main()
{
 int c;
 while((c = getchar())!= EOF)
 {
  if( getchar() == EOF )
    break;
  printf(" %d\n", c);
 }
  printf("%d %u %x- at EOF\n", c , c, c);
}

prints:

49
50
-1 4294967295 ffffffff- at EOF

for input:

1
2

Showing GIF In Android

Create CustomGifView.java which extends View Class

 public class CustomGifView extends View {

 private InputStream gifInputStream;
 private Movie gifMovie;
 private int movieWidth, movieHeight;
 private long movieDuration;
 private long mMovieStart;

 public CustomGifView(Context context) {
  super(context);
  init(context);
 }

 public CustomGifView(Context context, AttributeSet attrs) {
  super(context, attrs);
  init(context);
 }

 public CustomGifView(Context context, AttributeSet attrs, 
   int defStyleAttr) {
  super(context, attrs, defStyleAttr);
  init(context);
 }

 private void init(Context context){
  setFocusable(true);
  gifInputStream = context.getResources()
    .openRawResource(R.drawable.YOUR_IMAGE);

  gifMovie = Movie.decodeStream(gifInputStream);
  movieWidth = gifMovie.width();
  movieHeight = gifMovie.height();
  movieDuration = gifMovie.duration();
 }

 @Override
 protected void onMeasure(int widthMeasureSpec, 
   int heightMeasureSpec) {
  setMeasuredDimension(movieWidth, movieHeight);
 }

 public int getMovieWidth(){
  return movieWidth;
 }

 public int getMovieHeight(){
  return movieHeight;
 }

 public long getMovieDuration(){
  return movieDuration;
 }

 @Override
 protected void onDraw(Canvas canvas) {

  long now = android.os.SystemClock.uptimeMillis();
        if (mMovieStart == 0) {   // first time
            mMovieStart = now;
        }

        if (gifMovie != null) {

            int dur = gifMovie.duration();
            if (dur == 0) {
                dur = 1000;
            }

            int relTime = (int)((now - mMovieStart) % dur);

            gifMovie.setTime(relTime);

            gifMovie.draw(canvas, 0, 0);
            invalidate();

        }

 }

 }

Now call this class in your XML

 <Your_PackageName.CustomGifView
        android:id="@+id/gifview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Another Tricks

For animation functionality you may visit

http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html

Two options for runtime type checking with generics:

Option 1 - Corrupt your constructor

Let's assume you are overriding indexOf(...), and you want to check the type just for performance, to save yourself iterating the entire collection.

Make a filthy constructor like this:

public MyCollection<T>(Class<T> t) {

    this.t = t;
}

Then you can use isAssignableFrom to check the type.

public int indexOf(Object o) {

    if (
        o != null &&

        !t.isAssignableFrom(o.getClass())

    ) return -1;

//...

Each time you instantiate your object you would have to repeat yourself:

new MyCollection<Apples>(Apples.class);

You might decide it isn't worth it. In the implementation of ArrayList.indexOf(...), they do not check that the type matches.

Option 2 - Let it fail

If you need to use an abstract method that requires your unknown type, then all you really want is for the compiler to stop crying about instanceof. If you have a method like this:

protected abstract void abstractMethod(T element);

You can use it like this:

public int indexOf(Object o) {

    try {

        abstractMethod((T) o);

    } catch (ClassCastException e) {

//...

You are casting the object to T (your generic type), just to fool the compiler. Your cast does nothing at runtime, but you will still get a ClassCastException when you try to pass the wrong type of object into your abstract method.

NOTE 1: If you are doing additional unchecked casts in your abstract method, your ClassCastExceptions will get caught here. That could be good or bad, so think it through.

NOTE 2: You get a free null check when you use instanceof. Since you can't use it, you may need to check for null with your bare hands.

An inheritor of a base class should have an "is a" relationship. Interface represents An "implements a" relationship. So only use a base class when your inheritors will maintain the is a relationship.

I was getting this error because every time a user push some content, the group of the file changed to the user. And then if some other user tried to push into the repository, it caused permission error and the push was rejected. So one need to ask your sysadmin to change the settings of the repository so that group of any file in the repository is not changed for any push by any user.

To avoid such problem, please ensure that when you initialize your git repository, use the command "git init --shared=group".

There are a few yet to be mentioned techniques available for you. Start with setting the contentType property in your ajax params.

Building on pradeek's example:

$('form').submit(function (e) {
    var data;

    data = new FormData();
    data.append('file', $('#file')[0].files[0]);

    $.ajax({
        url: 'http://hacheck.tel.fer.hr/xml.pl',
        data: data,
        processData: false,
        type: 'POST',

        // This will override the content type header, 
        // regardless of whether content is actually sent.
        // Defaults to 'application/x-www-form-urlencoded'
        contentType: 'multipart/form-data', 

        //Before 1.5.1 you had to do this:
        beforeSend: function (x) {
            if (x && x.overrideMimeType) {
                x.overrideMimeType("multipart/form-data");
            }
        },
        // Now you should be able to do this:
        mimeType: 'multipart/form-data',    //Property added in 1.5.1

        success: function (data) {
            alert(data);
        }
    });

    e.preventDefault();
});

In some cases when forcing jQuery ajax to do non-expected things, the beforeSend event is a great place to do it. For a while people were using beforeSend to override the mimeType before that was added into jQuery in 1.5.1. You should be able to modify just about anything on the jqXHR object in the before send event.

You can use the built-in forEach function for arrays.

Like this:

//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
    element.product_desc = element.product_desc.substring(0,10);
});

Your version wasn't wrong though. It should look more like this:

for(let i=0; i<data.products.length; i++){
    console.log(data.products[i].product_desc); //use i instead of 0
}

When you say $(document).ready(f), you tell script engine to do the following:

1. get the object document and push it, since it's not in local scope, it must do a hash table lookup to find where document is, fortunately document is globally bound so it is a single lookup.
2. find the object $ and select it, since it's not in local scope, it must do a hash table lookup, which may or may not have collisions.
3. find the object f in global scope, which is another hash table lookup, or push function object and initialize it.
4. call ready of selected object, which involves another hash table lookup into the selected object to find the method and invoke it.
5. done.

In the best case, this is 2 hash table lookups, but that's ignoring the heavy work done by jQuery, where $ is the kitchen sink of all possible inputs to jQuery, so another map is likely there to dispatch the query to correct handler.

Alternatively, you could do this:

window.onload = function() {...}

which will

1. find the object window in global scope, if the JavaScript is optimized, it will know that since window isn't changed, it has already the selected object, so nothing needs to be done.
2. function object is pushed on the operand stack.
3. check if onload is a property or not by doing a hash table lookup, since it is, it is called like a function.

In the best case, this costs a single hash table lookup, which is necessary because onload must be fetched.

Ideally, jQuery would compile their queries to strings that can be pasted to do what you wanted jQuery to do but without the runtime dispatching of jQuery. This way you have an option of either

1. do dynamic dispatch of jquery like we do today.
2. have jQuery compile your query to pure JavaScript string that can be passed to eval to do what you want.
3. copy the result of 2 directly into your code, and skip the cost of eval.

Having something in an anonymous namespace means it's local to this translation unit (.cpp file and all its includes) this means that if another symbol with the same name is defined elsewhere there will not be a violation of the One Definition Rule (ODR).

This is the same as the C way of having a static global variable or static function but it can be used for class definitions as well (and should be used rather than static in C++).

All anonymous namespaces in the same file are treated as the same namespace and all anonymous namespaces in different files are distinct. An anonymous namespace is the equivalent of:

namespace __unique_compiler_generated_identifer0x42 {
    ...
}
using namespace __unique_compiler_generated_identifer0x42;

A dictionary cannot be directly used as a data source, you should do more.

SortedDictionary<string, int> userCache =  UserCache.getSortedUserValueCache();
KeyValuePair<string, int> [] ar= new KeyValuePair<string,int>[userCache.Count];
userCache.CopyTo(ar, 0);
comboBox1.DataSource = ar; new BindingSource(ar, "Key"); //This line is causing the error
comboBox1.DisplayMember = "Value";
comboBox1.ValueMember = "Key";

The use of _New is useful when working on pages that are Iframed. Since target="_blank" doesn't do the trick and opens the page on the same iframe... target new is the best solution for Iframe Pages. Just my five cents.

Switch Target framework to 4.5.2 or something higher and bring it back to your original version (example: 4.5) then when you build, it will work.

I am on a 64 bit system, and I only got this to work after installing both the 32 and 64 bit versions of the redistributable. I did not try the 64 bit version by itself due to the other posters' warnings about using the 32 bit version (and am too lazy to uninstall the 32 bit version now that I have it working), so I don't know if the 32 bit version is needed or not in cases like mine.

This is PKCS#1 format of a private key. Try this code. It doesn't use Bouncy Castle or other third-party crypto providers. Just java.security and sun.security for DER sequece parsing.

Kotlin Solution

view.isVisible = true
view.isInvisible = true
view.isGone = true

// For these to work, you need to use androidx and import:
import androidx.core.view.isVisible // or isInvisible/isGone

Kotlin Extension Solution

If you'd like them to be more consistent length, work for nullable views, and lower the chance of writing the wrong boolean, try using these custom extensions:

// Example
view.hide()

fun View?.show() {
    if (this == null) return
    if (!isVisible) isVisible = true
}

fun View?.hide() {
    if (this == null) return
    if (!isInvisible) isInvisible = true
}

fun View?.gone() {
    if (this == null) return
    if (!isGone) isGone = true
}

To make conditional visibility simple, also add these:

fun View?.show(visible: Boolean) {
    if (visible) show() else gone()
}

fun View?.hide(hide: Boolean) {
    if (hide) hide() else show()
}

fun View?.gone(gone: Boolean = true) {
    if (gone) gone() else show()
}

    /* START --- scroll till anchor */
        (function($) {
             $.fn.goTo = function() {
                  var top_menu_height=$('#div_menu_header').height() + 5 ;
                  //alert ( 'top_menu_height is:' + top_menu_height );
                  $('html, body').animate({
                        scrollTop: (-1)*top_menu_height + $(this).offset().top + 'px'
                  }, 500);
                  return this; // for chaining...
             }
        })(jQuery);

        $(document).ready(function(){

          var url = document.URL, idx = url.indexOf("#") ;
          var hash = idx != -1 ? url.substring(idx+1) : "";

          $(window).load(function(){
             // Remove the # from the hash, as different browsers may or may not include it
             var anchor_to_scroll_to = location.hash.replace('#','');
             if ( anchor_to_scroll_to != '' ) {
                 anchor_to_scroll_to = '#' + anchor_to_scroll_to ;
                 $(anchor_to_scroll_to).goTo();
             }
            });
        });
    /* STOP --- scroll till anchror */

Something else that was not obvious, to me at least, was that the when using Mongoose's third parameter to avoid replacing the actual collection with a new one with the same name, the new Schema(...) is actually only a placeholder, and doesn't interfere with the exisitng schema so

var User = mongoose.model('User', new Schema({ url: String, text: String, id: Number}, { collection : 'users' }));   // collection name;
User.find({}, function(err, data) { console.log(err, data, data.length);});

works fine and returns all fields - even if the actual (remote) Schema contains none of these fields. Mongoose will still want it as new Schema(...), and a variable almost certainly won't hack it.

set -x is fine, but if you do something like:

set -x;
command;
set +x;

it would result in printing

+ command
+ set +x;

You can use a subshell to prevent that such as:

(set -x; command)

which would just print the command.

What's happening is that the shell is expanding "*test.c" into a list of files. Try escaping the asterisk as:

find . -name \*test.c

[your Array name] = Empty

Then the array will be without content and can be filled again.

Another approach, if you don't care about whitespace being ignored:

for char in $(sed -E s/'(.)'/'\1 '/g <<<"$your_string"); do
    # Handle $char here
done

Is there a specific reason you want to use FileNameExtensionFilter? I know this works..

private File[] getNewTextFiles() {
    return dir.listFiles(new FilenameFilter() {
        @Override
        public boolean accept(File dir, String name) {
            return name.toLowerCase().endsWith(".txt");
        }
    });
}

You can also do

 Pushd "%~dp0"

Which also takes running from a unc path into consideration.

On unix systems, you can use the following command to determine where git is installed:

whereis git

If you are using MacOS and did a recent update, it is possible you have to agree to the licence terms again. Try typing 'git' in a terminal, and see if you get the following message:

Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

Is the recommendation to include CSS before JavaScript invalid?

Not if you treat it as simply a recommendation. But if your treat it as a hard and fast rule?, yes, it is invalid.

From https://developer.mozilla.org/en-US/docs/Web/Reference/Events/DOMContentLoaded

Stylesheet loads block script execution, so if you have a <script> after a <link rel="stylesheet" ...> the page will not finish parsing - and DOMContentLoaded will not fire - until the stylesheet is loaded.

It appears that you need to know what each script relies on and make sure that execution of the script is delayed until after the right completion event. If the script relies only on the DOM, it can resume in ondomready/domcontentloaded, if it relies on images to be loaded or stylesheets to be applied, then if I read the above reference correctly, that code must be deferred until the onload event.

I don't think that one sock size fits all, even though that is the way they are sold and I know that one shoe size does not fit all. I don't think that there is a definitive answer to which to load first, styles or script. It is more a case by case decision of what must be loaded in what order and what can be deferred until later as not being on the "critical path".

To speak to the observer that commented that it is better to delay the users ability to interact until the sheet is pretty. There are many of you out there and you annoy your counterparts that feel the opposite. They came to a site to accomplish a purpose and delays to their ability to interact with a site while waiting for things that don't matter to finish loading are very frustrating. I am not saying that you are wrong, only that you should be aware that there is another faction that exists that does not share your priority.

This question particularly applies to all of the ads being placed on web sites. I would love it if site authors rendered just placeholder divs for the ad content and made sure that their site was loaded and interactive before injecting the ads in an onload event. Even then I would like to see the ads loaded serially instead of all at once because they impact my ability to even scroll the site content while the bloated ads are loading. But that is just one persons point of view.

• Know your users and what they value.
• Know your users and what browsing environment they use.
• Know what each file does, and what its pre-requisites are. Making everything work will take precedence over both speed and pretty.
• Use tools that show you the network time line when developing.
• Test in each of the environments that your users use. It may be needed to dynamically (server side, when creating the page) alter the order of loading based on the users environment.
• When in doubt, alter the order and measure again.
• It is possible that intermixing styles and scripts in the load order will be optimal; not all of one then all of the other.
• Experiment not just what order to load the files but where. Head? In Body? After Body? DOM Ready/Loaded? Loaded?
• Consider async and defer options when appropriate to reduce the net delay the user will experience before being able to interact with the page. Test to determine if they help or hurt.
• There will always be trade offs to consider when evaluating the optimal load order. Pretty vs. Responsive being just one.

Everyone is saying to use ChronoUnit.DAYS.between but that just delegates to another method you could call yourself. So you could also do firstDate.until(secondDate, ChronoUnit.DAYS).

The docs for both actually mention both approaches and say to use whichever one is more readable.

This should further clarify the points:

a = int(raw_input('Enter the index'))
str1 = 'Example'
leng = len(str1)
if (a < (len-1)) and (a > (-len)):
    print str1[a]
else:
    print('Index overflow')

Input 3 Output m

Input -3 Output p

JDK's can be downloaded from here as zip file nor .exe http://installbuilder.bitrock.com/java/

sp_lock

When reading sp_lock information, use the OBJECT_NAME( ) function to get the name of a table from its ID number, for example:

SELECT object_name(16003073)

EDIT :

There is another proc provided by microsoft which reports objects without the ID translation : http://support.microsoft.com/kb/q255596/

Export you Java Project as an Runnable Jar file rather than Jar.

I exported my project as Jar and even though the Manifest was present it gave me the error no main manifest attribute in jar even though the Manifest file was present in the Jar. However there is only one entry in the Manifest file and it didn't specify the Main class or Function to execute or any dependent JAR's

After exporting it as Runnable Jar file it works as expected.

For some time now, you can also only rely on the data.table package and its IDate class plus associated functions. (Check ?as.IDate()). So, no need to additionally install lubridate.

require(data.table)

some_date <- c("01/02/1979", "03/04/1980")
month(as.IDate(some_date, '%d/%m/%Y')) # all data.table functions

Since you're using JPA, use the Lob annotation (and optionally the Column annotation). Here is what the JPA specification says about it:

9.1.19 Lob Annotation

A Lob annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use the Lob annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with the Basic annotation. A Lob may be either a binary or character type. The Lob type is inferred from the type of the persistent field or property, and except for string and character-based types defaults to Blob.

So declare something like this:

@Lob 
@Column(name="CONTENT", length=512)
private String content;

References

• JPA 1.0 specification:
  • Section 9.1.19 "Lob Annotation"

Well, the way you're timing things looks pretty nasty to me. It would be much more sensible to just time the whole loop:

var stopwatch = Stopwatch.StartNew();
for (int i = 1; i < 100000000; i++)
{
    Fibo(100);
}
stopwatch.Stop();
Console.WriteLine("Elapsed time: {0}", stopwatch.Elapsed);

That way you're not at the mercy of tiny timings, floating point arithmetic and accumulated error.

Having made that change, see whether the "non-catch" version is still slower than the "catch" version.

EDIT: Okay, I've tried it myself - and I'm seeing the same result. Very odd. I wondered whether the try/catch was disabling some bad inlining, but using [MethodImpl(MethodImplOptions.NoInlining)] instead didn't help...

Basically you'll need to look at the optimized JITted code under cordbg, I suspect...

EDIT: A few more bits of information:

• Putting the try/catch around just the n++; line still improves performance, but not by as much as putting it around the whole block
• If you catch a specific exception (ArgumentException in my tests) it's still fast
• If you print the exception in the catch block it's still fast
• If you rethrow the exception in the catch block it's slow again
• If you use a finally block instead of a catch block it's slow again
• If you use a finally block as well as a catch block, it's fast

Weird...

EDIT: Okay, we have disassembly...

This is using the C# 2 compiler and .NET 2 (32-bit) CLR, disassembling with mdbg (as I don't have cordbg on my machine). I still see the same performance effects, even under the debugger. The fast version uses a try block around everything between the variable declarations and the return statement, with just a catch{} handler. Obviously the slow version is the same except without the try/catch. The calling code (i.e. Main) is the same in both cases, and has the same assembly representation (so it's not an inlining issue).

In each case the * shows where the debugger entered in a simple "step-into".

EDIT: Okay, I've now looked through the code and I think I can see how each version works... and I believe the slower version is slower because it uses fewer registers and more stack space. For small values of n that's possibly faster - but when the loop takes up the bulk of the time, it's slower.

Possibly the try/catch block forces more registers to be saved and restored, so the JIT uses those for the loop as well... which happens to improve the performance overall. It's not clear whether it's a reasonable decision for the JIT to not use as many registers in the "normal" code.

EDIT: Just tried this on my x64 machine. The x64 CLR is much faster (about 3-4 times faster) than the x86 CLR on this code, and under x64 the try/catch block doesn't make a noticeable difference.

All the answers that include creating an new object from Form class are absolutely creating new form. But you can use Text property of ActiveForm subclass in Form class. For example:

        public Form1()
    {
        InitializeComponent();
        Form1.ActiveForm.Text = "Your Title";
    }

Here's one way:

Stream myStream = null;
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = theDialog.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}

Modified from here:MSDN OpenFileDialog.OpenFile

EDIT Here's another way more suited to your needs:

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
    OpenFileDialog theDialog = new OpenFileDialog();
    theDialog.Title = "Open Text File";
    theDialog.Filter = "TXT files|*.txt";
    theDialog.InitialDirectory = @"C:\";

    {
        string filename = theDialog.FileName;

        string[] filelines = File.ReadAllLines(filename);

        int linesPerEmployee = 4;
        int currEmployeeLine = 0;

        Employee employee = new Employee();
        for (int a = 0; a < filelines.Length; a++)
        {

            //check if to move to next employee
            if (a != 0 && a % linesPerEmployee == 0)
            {
                employeeList.Add(employee);
                employee = new Employee();
                currEmployeeLine = 1;
            }

            else

            switch (currEmployeeLine)
            {
                case 1:
                    employee.EmployeeNum = Convert.ToInt32(filelines[a].Trim());
                    break;
                case 2:
                    employee.Name = filelines[a].Trim();
                    break;
                case 3:

                    break;
                case 4:
                    string[] splitLines = filelines[a].Split(' ');

                    employee.Wage = Convert.ToDouble(splitLines[0].Trim());
                    employee.Hours = Convert.ToDouble(splitLines[1].Trim());
                    break;


            }

        }
        //Test to see if it works
        foreach (Employee emp in employeeList)

Very simple, you create an array containing zeros using the reference shape:

result = np.zeros(b.shape)
# actually you can also use result = np.zeros_like(b) 
# but that also copies the dtype not only the shape

and then insert the array where you need it:

result[:a.shape[0],:a.shape[1]] = a

and voila you have padded it:

print(result)
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

You can also make it a bit more general if you define where your upper left element should be inserted

result = np.zeros_like(b)
x_offset = 1  # 0 would be what you wanted
y_offset = 1  # 0 in your case
result[x_offset:a.shape[0]+x_offset,y_offset:a.shape[1]+y_offset] = a
result

array([[ 0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.],
       [ 0.,  1.,  1.,  1.,  1.,  1.],
       [ 0.,  1.,  1.,  1.,  1.,  1.]])

but then be careful that you don't have offsets bigger than allowed. For x_offset = 2 for example this will fail.

If you have an arbitary number of dimensions you can define a list of slices to insert the original array. I've found it interesting to play around a bit and created a padding function that can pad (with offset) an arbitary shaped array as long as the array and reference have the same number of dimensions and the offsets are not too big.

def pad(array, reference, offsets):
    """
    array: Array to be padded
    reference: Reference array with the desired shape
    offsets: list of offsets (number of elements must be equal to the dimension of the array)
    """
    # Create an array of zeros with the reference shape
    result = np.zeros(reference.shape)
    # Create a list of slices from offset to offset + shape in each dimension
    insertHere = [slice(offset[dim], offset[dim] + array.shape[dim]) for dim in range(a.ndim)]
    # Insert the array in the result at the specified offsets
    result[insertHere] = a
    return result

And some test cases:

import numpy as np

# 1 Dimension
a = np.ones(2)
b = np.ones(5)
offset = [3]
pad(a, b, offset)

# 3 Dimensions

a = np.ones((3,3,3))
b = np.ones((5,4,3))
offset = [1,0,0]
pad(a, b, offset)

here is what you should put

local stringnumber = "10"
local a = tonumber(stringnumber)
print(a + 10)

output:

20

Try this, it's working for me.

NSString *str = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"paylines.txt"];  

For simulator

NSURL *rtfUrl = [[NSBundle mainBundle] URLForResource:@"paylines" withExtension:@".txt"];

As of Laravel v7.X, the framework now comes with a minimal API wrapped around the Guzzle HTTP client. It provides an easy way to make get, post, put, patch, and delete requests using the HTTP Client:

use Illuminate\Support\Facades\Http;

$response = Http::get('http://test.com');
$response = Http::post('http://test.com');
$response = Http::put('http://test.com');
$response = Http::patch('http://test.com');
$response = Http::delete('http://test.com');

You can manage responses using the set of methods provided by the Illuminate\Http\Client\Response instance returned.

$response->body() : string;
$response->json() : array;
$response->status() : int;
$response->ok() : bool;
$response->successful() : bool;
$response->serverError() : bool;
$response->clientError() : bool;
$response->header($header) : string;
$response->headers() : array;

Please note that you will, of course, need to install Guzzle like so:

composer require guzzlehttp/guzzle

There are a lot more helpful features built-in and you can find out more about these set of the feature here: https://laravel.com/docs/7.x/http-client

This is definitely now the easiest way to make external API calls within Laravel.

The onload property of the GlobalEventHandlers mixin is an event handler for the load event of a Window, XMLHttpRequest, element, etc., which fires when the resource has loaded.

So basically javascript already has onload method on window which get executed which page fully loaded including images...

You can do something:

var spinner = true;

window.onload = function() {
  //whatever you like to do now, for example hide the spinner in this case
  spinner = false;
};

1. The degree sign belongs to the number, and not to the "C". You can regard the degree sign as a number symbol, just like the minus sign.
2. There shall not be any space between the digits and the degree sign.
3. There shall be a non-breaking space between the degree sign and the "C".

You can't easily communicate back to the CPU from within GLSL. Using glslDevil or other tools is your best bet.

A printf would require trying to get back to the CPU from the GPU running the GLSL code. Instead, you can try pushing ahead to the display. Instead of trying to output text, output something visually distinctive to the screen. For example you can paint something a specific color only if you reach the point of your code where you want add a printf. If you need to printf a value you can set the color according to that value.

Depending on your version of Tomcat, this might be a simple problem (bug) with a 0-byte log file. Take a look at /var/log/tomcatX.Y where X.Y is your version you're working with and check if the log file catalina.out is read- and writeable. If it has 0 byte and is not accessible, then simply delete it and re-start Tomcat. This solved the problem for us a few times already.

Use CSS position: absolute; followed by top: 0px; left 0px; in the style attribute of each DIV. Replace the pixel values with whatever you want.

You can use z-index: x; to set the vertical "order" (which one is "on top"). Replace x with a number, higher numbers are on top of lower numbers.

Here is how your new code would look:

<div>
  <div id="backdrop" style="z-index: 1; position: absolute; top: 0px; left: 0px;"><img alt="" src='/backdrop.png' /></div>
  <div id="curtain" style="z-index: 2; position: absolute; top: 0px; left: 0px; background-image:url(/curtain.png);background-position:100px 200px; height:250px; width:500px;">&nbsp;</div>
</div>

Add multiple classes:

$("p").addClass("class1 class2 class3");

or in cascade:

$("p").addClass("class1").addClass("class2").addClass("class3");

Very similar also to remove more classes:

$("p").removeClass("class1 class2 class3");

or in cascade:

$("p").removeClass("class1").removeClass("class2").removeClass("class3");

document.getElementById("someFormId").elements;

This collection will also contain <select>, <textarea> and <button> elements (among others), but you probably want that.

Had the same issue and got curious about the performance of each solution.

Here's is the %timeit:

import numpy as np
lst = [['a','b','c'], [1,2,3], ['x','y','z']]

The first numpy-way, transforming the array:

%timeit list(np.array(lst).T[0])
4.9 µs ± 163 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

Fully native using list comprehension (as explained by @alecxe):

%timeit [item[0] for item in lst]
379 ns ± 23.1 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

Another native way using zip (as explained by @dawg):

%timeit list(zip(*lst))[0]
585 ns ± 7.26 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

Second numpy-way. Also explained by @dawg:

%timeit list(np.array(lst)[:,0])
4.95 µs ± 179 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

Surprisingly (well, at least for me) the native way using list comprehension is the fastest and about 10x faster than the numpy-way. Running the two numpy-ways without the final list saves about one µs which is still in the 10x difference.

Note that, when I surrounded each code snippet with a call to len, to ensure that Generators run till the end, the timing stayed the same.

unicodestring = '\xa0'

decoded_str = unicodestring.decode("windows-1252")
encoded_str = decoded_str.encode('ascii', 'ignore')

Works for me

Netflix also implements this feature

(function() {
    try {
        var $_console$$ = console;
        Object.defineProperty(window, "console", {
            get: function() {
                if ($_console$$._commandLineAPI)
                    throw "Sorry, for security reasons, the script console is deactivated on netflix.com";
                return $_console$$
            },
            set: function($val$$) {
                $_console$$ = $val$$
            }
        })
    } catch ($ignore$$) {
    }
})();

They just override console._commandLineAPI to throw security error.

You could deal with a json array and the sort function. It is a pretty easy maintanable structure to manipulate (ex: sorting).

Untested, but here's the idea. That would support multiple ordering and sequential ordering if you pass in a array in which you put the columns in the order they should be ordered by.

var DATA_TABLE = {
    {name: 'George', lastname: 'Blarr', age:45},
    {name: 'Bob', lastname: 'Arr', age: 20}
    //...
};

function sortDataTable(arrayColNames, asc) { // if not asc, desc
    for (var i=0;i<arrayColNames.length;i++) {
        var columnName = arrayColNames[i];
        DATA_TABLE = DATA_TABLE.sort(function(a,b){
            if (asc) {
                return (a[columnName] > b[columnName]) ? 1 : -1;
            } else {
                return (a[columnName] < b[columnName]) ? 1 : -1;
            }
        });
    }
}

function updateHTMLTable() {
    // update innerHTML / textContent according to DATA_TABLE
    // Note: textContent for firefox, innerHTML for others
}

Now let's imagine you need to order by lastname, then name, and finally by age.

var orderAsc = true;
sortDataTable(['lastname', 'name', 'age'], orderAsc);

It should result in something like :

{name: 'Jack', lastname: 'Ahrl', age: 20},
{name: 'Jack', lastname: 'Ahrl', age: 22},
//...

I would not recommend you to start session just to get some unique id. Instead, use such things as uniqid() because it's intended to return unique id.

However, if you already have session, then, of course, use session_id() to get your session id - but do not rely on that, because "unique id" isn't same as "session id" in common sense: for example, multiple tabs in most browsers will use same process, thus, use same session identifier in result - and, therefore, different connections will have same id. It's your decision about desired behavior, I've mentioned this just to show the difference between session id and unique id.

You can set your hash directly to URL too.

window.location.hash = "YourHash";

The result : http://url#YourHash

The answer you're looking for in 2020 and beyond:

• setColorFilter(color, mode) is deprecated since API 29 (as discussed here)
• button.setBackgroundColor(color) messes with the button style

Now the proper way to set a buttons color is using BlendModeColorFilter() (see documentation).

Usage:

btn.background.colorFilter = BlendModeColorFilter(color, BlendMode.MULTIPLY)

If you work with older APIs too:

fun setButtonColor(btn: Button, color: Int) {
    if (Build.VERSION.SDK_INT >= 29)
        btn.background.colorFilter = BlendModeColorFilter(color, BlendMode.MULTIPLY)
    else
        btn.background.setColorFilter(color, PorterDuff.Mode.MULTIPLY)
}

Please vote to help others finding this answer - it took me quite a while figuring this out ^^

Just installed MongoDB via Homebrew. At the end of the installation console, you can see an output as follows:

To start mongodb:

brew services start mongodb

Or, if you don't want/need a background service you can just run:

mongod --config /usr/local/etc/mongod.conf

So, brew services start mongodb, managed to run MongoDB as a service for me.

Correct expression is

"source " + (DT_STR,4,1252)DATEPART( "yyyy" , getdate() ) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "mm" , getdate() ), 2) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "dd" , getdate() ), 2) +".CSV"

 if ($("#Password").val() != $("#ConfirmPassword").val()) {
          alert("Passwords do not match.");
      }

A JQuery approach that will eliminate needless code.

Here's how to do this with lxml without having to hard-code the namespaces or scan the text for them (as Martijn Pieters mentions):

from lxml import etree
tree = etree.parse("filename")
root = tree.getroot()
root.findall('owl:Class', root.nsmap)

UPDATE:

5 years later I'm still running into variations of this issue. lxml helps as I showed above, but not in every case. The commenters may have a valid point regarding this technique when it comes merging documents, but I think most people are having difficulty simply searching documents.

Here's another case and how I handled it:

<?xml version="1.0" ?><Tag1 xmlns="http://www.mynamespace.com/prefix">
<Tag2>content</Tag2></Tag1>

xmlns without a prefix means that unprefixed tags get this default namespace. This means when you search for Tag2, you need to include the namespace to find it. However, lxml creates an nsmap entry with None as the key, and I couldn't find a way to search for it. So, I created a new namespace dictionary like this

namespaces = {}
# response uses a default namespace, and tags don't mention it
# create a new ns map using an identifier of our choice
for k,v in root.nsmap.iteritems():
    if not k:
        namespaces['myprefix'] = v
e = root.find('myprefix:Tag2', namespaces)

user double quote to get the exact value. like this:

echo "${var}"

and it will read your value correctly.

Here is one way:

const date1 = new Date('7/13/2010');_x000D_
const date2 = new Date('12/15/2010');_x000D_
const diffTime = Math.abs(date2 - date1);_x000D_
const diffDays = Math.ceil(diffTime / (1000 * 60 * 60 * 24)); _x000D_
console.log(diffTime + " milliseconds");_x000D_
console.log(diffDays + " days");

Observe that we need to enclose the date in quotes. The rest of the code gets the time difference in milliseconds and then divides to get the number of days. Date expects mm/dd/yyyy format.

your mail.php on config you declare host as smtp.mailgun.org and port is 587 while on env is different. you need to change your mail.php to

'host' => env('MAIL_HOST', 'mailtrap.io'),

'port' => env('MAIL_PORT', 2525),

if you desire to use mailtrap.Then run

php artisan config:cache

Alternatively, you can just do:

import matplotlib as mpl
label_size = 8
mpl.rcParams['xtick.labelsize'] = label_size 

SqlConnection con = new SqlConnection(@"Some Connection String");//connection object
SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);//SqlDataAdapter class object
da.SelectCommand.CommandType = CommandType.StoredProcedure; //command sype
da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123; //pass perametter
DataTable dt = new DataTable();  //dataset class object
da.Fill(dt); //call the stored producer

With RHEL 7 / CentOS 7, firewalld was introduced to manage iptables. IMHO, firewalld is more suited for workstations than for server environments.

It is possible to go back to a more classic iptables setup. First, stop and mask the firewalld service:

systemctl stop firewalld
systemctl mask firewalld

Then, install the iptables-services package:

yum install iptables-services

Enable the service at boot-time:

systemctl enable iptables

Managing the service

systemctl [stop|start|restart] iptables

Saving your firewall rules can be done as follows:

service iptables save

or

/usr/libexec/iptables/iptables.init save

The behavior depends on which version your repository has. Subversion 1.5 allows 4 types of merge:

1. merge sourceURL1[@N] sourceURL2[@M] [WCPATH]
2. merge sourceWCPATH1@N sourceWCPATH2@M [WCPATH]
3. merge [-c M[,N...] | -r N:M ...] SOURCE[@REV] [WCPATH]
4. merge --reintegrate SOURCE[@REV] [WCPATH]

Subversion before 1.5 only allowed the first 2 formats.

Technically you can perform all merges with the first two methods, but the last two enable subversion 1.5's merge tracking.

TortoiseSVN's options merge a range or revisions maps to method 3 when your repository is 1.5+ or to method one when your repository is older.

When merging features over to a release/maintenance branch you should use the 'Merge a range of revisions' command.

Only when you want to merge all features of a branch back to a parent branch (commonly trunk) you should look into using 'Reintegrate a branch'.

And the last command -Merge two different trees- is only usefull when you want to step outside the normal branching behavior. (E.g. Comparing different releases and then merging the differenct to yet another branch)

It's worked to me!

Attribute Contains Selector [name*=”value”]

This is the most generous of the jQuery attribute selectors that match against a value. It will select an element if the selector's string appears anywhere within the element's attribute value. Compare this selector with the Attribute Contains Word selector (e.g. [attr~="word"]), which is more appropriate in many cases.

In the first case you are declaring "int a" as a local variable(as declared inside a method) and local varible do not get default value.

But instance variable are given default value both for static and non-static.

Default value for instance variable:

int = 0

float,double = 0.0

reference variable = null

char = 0 (space character)

boolean = false

Try setting mapper.configure(DeserializationConfig.Feature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true)

or

mapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);

depending on your Jackson version.

One other difference is that xrange() can't support numbers bigger than C ints, so if you want to have a range using python's built in large number support, you have to use range().

You can't do it with the layout alone, I've tried. I ended up writing a very simple class to handle it, you can check it out on github. SquareImage.java Its part of a larger project but nothing a little copy and paste can't fix (licensed under Apache 2.0)

Essentially you just need to set the height/width equal to the other dimension (depending on which way you want to scale it)

Note: You can make it square without a custom class using the scaleType attribute but the view's bounds extend beyond the visible image, which makes it an issue if you are placing other views near it.

The problem, as the Traceback says, comes from the line x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ). Let's replace it in its context:

• x is an array equal to [x0 * n], so its length is 1
• you're iterating from 0 to n-2 (n doesn't matter here), and i is the index. In the beginning, everything is ok (here there's no beginning apparently... :( ), but as soon as i + 1 >= len(x) <=> i >= 0, the element x[i+1] doesn't exist. Here, this element doesn't exist since the beginning of the for loop.

To solve this, you must replace x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ) by x.append(x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] )).

Through the following steps you can do it .

In Eclipse window , Right Click on your Project from Package Explorer. 1. Select Properties, 2. Select Android from Properties, 3. Check "Is Library" check box, 4. If it is checked then Unchecked "Is Library" check box. 5. Click Apply and than OK.

There is also a XML way that Google recommends:

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:keepScreenOn="true">

Check Google Slides - Slide 16.

"Wakelocks are costly if forgotten (...) Consider using android:keepScreenOn to ensure correctness"

You can use

    CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
    CameraUpdate zoom = CameraUpdateFactory.zoomTo(12);

There is no easy way to get all DNS records for a domain in one instance. You can only view certain records for example, if you wanna see an A record for a certain domain you can use the command: dig a(type of record) domain.com. This is the same for all the other type of records you wanna see for that domain.

If your not familiar with the command line interface, you can also use a site like mxtoolbox.com. Wich is very handy tool for getting records of a domain.

I hope this answers your question.

This is one way.

    li span {
        margin-left: -11px;
    }

A tuple is used to define a slice of data from a cube; it is composed of an ordered collection of one member from one or more dimensions. A tuple is used to identify specific sections of multidimensional data from a cube; a tuple composed of one member from each dimension in a cube completely describes a cell value.

You do not need {{}} in when conditions. What you are searching for is:

- fail: msg="unsupported version"
  when: version not in acceptable_versions

Here is my solution:

arr = []
arr.append([1,2,3])
arr.append([4,5,6])
np_arr = np.array(arr)

-(IBAction)SegmentbtnCLK:(id)sender
{ [self sortArryofDictionary];
    [self.objtable reloadData];}
-(void)sortArryofDictionary
{ NSSortDescriptor *sorter;
    switch (sortcontrol.selectedSegmentIndex)
    {case 0:
            sorter=[[NSSortDescriptor alloc]initWithKey:@"Name" ascending:YES];
            break;
        case 1:
            sorter=[[NSSortDescriptor alloc]initWithKey:@"Age" ascending:YES];
            default:
            break; }
    NSArray *sortdiscriptor=[[NSArray alloc]initWithObjects:sorter, nil];
    [arr sortUsingDescriptors:sortdiscriptor];
    }

The solution in a more elegant way.

var myData=['237','124','255','124','366','255'];

console.log(Array.from(new Set(myData)).sort());

I know the question is very old, but maybe someone will come in handy

Why invent wheels yourself while there is a car ready for you? I just find this tools super easy and intuitive to use: Advanced Installer. This one minute video should be enough to impress you. Here is the illustrative user guide.

I like to accept a form post for my POST actions, even if I don't need it. For me it just feels like the right thing to do as you're supposedly posting something.

        //Code...
        return View();
    }

    [HttpPost]
    public ActionResult Index(FormCollection form)

I use public static fields to store shared data between activities, but to minimize its side effects, you may:

• Make only one field, or as few as possible, and reuse them, make them of type object and cast it to desired type in the receiving activity.
• Whenever any of them isn't useful anymore, set it explicitly to null to be collected by the garbage collector, before the next assignment.

Check out the help command:

svn help copy

  -r [--revision] arg      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED

To actually specify this on the command line using your example:

svn copy -r123 http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Where 123 would be the revision number in trunk you want to copy. As others have noted, you can also use the @ syntax. I prefer the clearer separation of the revision # from the URL, personally.

As noted in the help, you can replace a revision # with certain words as well:

svn copy -rPREV http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Would copy the "revision just before COMMITTED".

If you don't give any position to parent then by default it takes static. If you want to understand that difference refer to this example

Example 1::

http://jsfiddle.net/Cr9KB/1/

   #mainall
{

    background-color:red;
    height:150px;
    overflow:scroll
}

Here parent class has no position so element is placed according to body.

Example 2::

http://jsfiddle.net/Cr9KB/2/

#mainall
{
    position:relative;
    background-color:red;
    height:150px;
    overflow:scroll
}

In this example parent has relative position hence element are positioned absolute inside relative parent.

Both your queries are correct and should give you the right answer.

I would suggest the following query to troubleshoot your problem.

SELECT DISTINCT a,b,c,d,count(*) Count FROM my_table GROUP BY a,b,c,d
order by count(*) desc

That is add count(*) field. This will give you idea how many rows were eliminated using the group command.

You can use nslookup on the IP. Reverse DNS is defined with the .in-addr.arpa domain.

Example:

nslookup somedomain.com

yields 123.21.2.3, and then you do:

nslookup 123.21.2.3

this will ask 3.2.21.123.in-addr.arpa and yield the domain name (if there is one defined for reverse DNS).

Not exactly the case of actual context of this question, but this exception can be reproduced by the next query:

update users set dismissal_reason='he can't and don't want' where userid=123

Single quotes in words can't and don't broke the string. In case string have only one inside quote e.g. 'he don't want' oracle throws more relevant quoted string not properly terminated error, but in case of two SQL command not properly ended is thrown.

Summary: check your query for double single quotes.

I would do as below

rebase feature
git checkout -b feature2 origin/feature
git push -u origin feature2:feature2
Delete the old remote branch feature
git push -u origin feature:feature

Now the remote will have feature(rebased on latest master) and feature2(with old master head). This would allow you to compare later if you have done mistakes in reolving conflicts.

A library and demo with the complete source code for scrolling toolbars or any type of header can be downloaded here:

https://github.com/JohannBlake/JBHeaderScroll

Headers can be Toolbars, LinearLayouts, RelativeLayouts, or whatever type of view you use to create a header.

The scrollable area can be any type of scroll content including ListView, ScrollView, WebView, RecyclerView, RelativeLayout, LinearLayout or whatever you want.

There's even support for nested headers.

It is indeed a complex undertaking to synchronize headers (toolbars) and scrollable content the way it's done in Google Newsstand.

This library doesn't require implementing any kind of onScrollListener.

The solutions listed above by others are only half baked solutions that don't take into consideration that the top edge of the scrollable content area beneath the toolbar has to initially be aligned to the bottom edge of the toolbar and then during scrolling the content area needs to be repositioned and possibly resized. The JBHeaderScroll handles all these issues.

I know this is an old post, but i was having a problem like the OP and this is what i came up with.

Example of array you could pass. You could re order this if a particular order was required, but for this question this will do what is asked.

$argument_set = array (8 => 'lots', 5 => 'of', 1 => 'data', 2 => 'here');

This is manageable, easy to read and the data extraction points can be added and removed at a moments notice anywhere in coding and still avoid a massive rewrite. I used integer keys to tally with the OP original question but string keys could be used just as easily. In fact for readability I would advise it.

Stick this in an external file for ease

function unknown_number_arguments($argument_set) {

    foreach ($argument_set as $key => $value) {

        # create a switch with all the cases you need. as you loop the array 
        # keys only your submitted $keys values will be found with the switch. 
        switch ($key) {
            case 1:
                # do stuff with $value
                break;
            case 2:
                # do stuff with $value;
                break;
            case 3:
                # key 3 omitted, this wont execute 
                break;
            case 5:
                # do stuff with $value;
                break;
            case 8:
                # do stuff with $value;
                break;
            default:
                # no match from the array, do error logging?
                break;
        }
    }
return;
}

put this at the start if the file.

$argument_set = array(); 

Just use these to assign the next piece of data use numbering/naming according to where the data is coming from.

$argument_set[1][] = $some_variable; 

And finally pass the array

unknown_number_arguments($argument_set);

Also, please make sure you installed the correct version of apache on your computer. For example, not install a x86 on a 64bit system. Vice versa.

There are many ways using them you can enable/disable any element :

Approach 1

$("#txtName").attr("disabled", true);

Approach 2

$("#txtName").attr("disabled", "disabled");

If you are using jQuery 1.7 or higher version then use prop(), instead of attr().

$("#txtName").prop("disabled", "disabled");

If you wish to enable any element then you just have to do opposite of what you did to make it disable. However jQuery provides another way to remove any attribute.

Approach 1

$("#txtName").attr("disabled", false);

Approach 2

$("#txtName").attr("disabled", "");

Approach 3

$("#txtName").removeAttr("disabled");

Again, if you are using jQuery 1.7 or higher version then use prop(), instead of attr(). That's is. This is how you enable or disable any element using jQuery.

I did a bit of research regarding this & I have summarised my findings so far in below table

So the recommended solution is to write a a server side script to parse the Accept-Language header & pass it to client for setting the language of the website. It's weird that why the server would be needed to detect the language preference of client but that's how it is as of now There are other various hacks available to detect the language but reading the Accept-Language header is the recommended solution as per my understanding.

The GPL mkfile is just a (ba)sh script wrapper around dd; BSD's mkfile just memsets a buffer with non-zero and writes it repeatedly. I would not expect the former to out-perform dd. The latter might edge out dd if=/dev/zero slightly since it omits the reads, but anything that does significantly better is probably just creating a sparse file.

Absent a system call that actually allocates space for a file without writing data (and Linux and BSD lack this, probably Solaris as well) you might get a small improvement in performance by using ftrunc(2)/truncate(1) to extend the file to the desired size, mmap the file into memory, then write non-zero data to the first bytes of every disk block (use fgetconf to find the disk block size).

As said in recent comments, string::localeCompare supports case insensitive comparisons (among other powerful things).

Here's a simple example

'xyz'.localeCompare('XyZ', undefined, { sensitivity: 'base' }); // returns 0

And a generic function you could use

function equalsIgnoringCase(text, other) {
    return text.localeCompare(other, undefined, { sensitivity: 'base' }) === 0;
}

Note that instead of undefined you should probably enter the specific locale you are working with. This is important as denoted in the MDN docs

in Swedish, ä and a are separate base letters

Sensitivity options

Browser support

As of time of posting, UC Browser for Android and Opera Mini do not support locale and options parameters. Please check https://caniuse.com/#search=localeCompare for up to date info.

To avoid check on every digest cycle, we can change the height of the div when the window height gets changed.

http://jsfiddle.net/zbjLh/709/

<div ng-app="miniapp" resize>
  Testing
</div>

.

var app = angular.module('miniapp', []);

app.directive('resize', function ($window) {
    return function (scope, element) {
        var w = angular.element($window);
        var changeHeight = function() {element.css('height', (w.height() -20) + 'px' );};  
            w.bind('resize', function () {        
              changeHeight();   // when window size gets changed             
        });  
        changeHeight(); // when page loads          
    }
})

private void setLanguage(String language) {
    Locale locale = new Locale(language);
    Locale.setDefault(locale);
    Configuration config = new Configuration();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        config.setLocale(locale);
    } else {
        config.locale = locale;
    }
    getResources().updateConfiguration(config,
            getResources().getDisplayMetrics());

}

For Gradle look here: https://docs.gradle.org/current/dsl/org.gradle.api.tasks.SourceSetOutput.html. "For example: Java plugin will use those dirs in calculating class paths and for jarring the content; IDEA and Eclipse plugins will put those folders on relevant classpath."

So its depend on plugin build in configs unless you don't define them explicit in config file.

This might not be very applicable to others, but my problem was that the changes I made was NOT saved yet! Press CMD + S and save your work before building on top of it.

this will work for sure..

RelativeLayout layout = new RelativeLayout(R.layout.your_layour); 
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.CENTER_IN_PARENT);
params.addRule(LinearLayout.CENTER_IN_PARENT);
textView.setLayoutParams(params);
textView.setGravity(Gravity.CENTER);

layout.addView(textView);

setcontentView(layout);

Java 8 Solution: I just had this problem and solved it by adding the remote site's certificate to my Java keystore. My solution was based on the solution at the myshittycode blog, which was based on a previous solution in mykong's blog. These blog article solutions boil down to downloading a program called InstallCert, which is a Java class you can run from the command line to obtain the certificate. You then proceed to install the certificate in Java's keystore.

The InstallCert Readme worked perfectly for me. You just need to run the following commands:

1. javac InstallCert.java
2. java InstallCert [host]:[port] (Enter the given list number of the certificate you want to add in the list when you run the command - likely just 1)
3. keytool -exportcert -alias [host]-1 -keystore jssecacerts -storepass changeit -file [host].cer
4. sudo keytool -importcert -alias [host] -keystore [path to system keystore] -storepass changeit -file [host].cer

See the referenced README file for an example if need be.

What you should get as output with this code is:

Array ()

... this is exactly how you get just one row, you don't need a while loop. Are you sure you're printing the right variable?

Bootstrap tabs are not responsive out of the box. Responsive, IMO, is a style change, changing functions is Adaptive. There are a few plugins to turn the Bootstrap 3 tabs into a Collapse component. The best and most updated one is : https://github.com/flatlogic/bootstrap-tabcollapse.

Here's one way of implementing it:

DEMO: http://jsbin.com/zibani/1/

EDIT: http://jsbin.com/zibani/1/edit

This turns the content into a collapse component:

Dependencies:

1. Bootstrap 3.2 css or higher but still in the 3 series
2. Bootstrap 3.2 jQuery or higher but still in the 3 series
3. Compatible version of bootstrap-tabcollapse.js

HTML -- same as question with class name addition:

       <ul class="nav nav-tabs content-tabs" id="maincontent" role="tablist">

jQuery:

$(document).ready(function() {

    // DEPENDENCY: https://github.com/flatlogic/bootstrap-tabcollapse
    $('.content-tabs').tabCollapse();

    // initialize tab function
    $('.nav-tabs a').click(function(e) {
        e.preventDefault();
        $(this).tab('show');
    });

});

CSS -- optional for fat fingers and active states:

.panel-heading {
    padding: 0
}
.panel-heading a {
    display: block;
    padding: 20px 10px;
}
.panel-heading a.collapsed {
    background: #fff
}
.panel-heading a {
    background: #f7f7f7;
    border-radius: 5px;
}
.panel-heading a:after {
    content: '-'
}
.panel-heading a.collapsed:after {
    content: '+'
}
.nav.nav-tabs li a,
.nav.nav-tabs li.active > a:hover,
.nav.nav-tabs li.active > a:active,
.nav.nav-tabs li.active > a:focus {
    border-bottom-width: 0px;
    outline: none;
}
.nav.nav-tabs li a {
    padding-top: 20px;
    padding-bottom: 20px;
}
.tab-pane {
    background: #fff;
    padding: 10px;
    border: 1px solid #ddd;
    margin-top: -1px;
}

The key attribute is align-self: center:

.container {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
}_x000D_
_x000D_
img {_x000D_
  max-width: 100%;_x000D_
}_x000D_
_x000D_
img.align-self {_x000D_
  align-self: center;_x000D_
}

<div class="container">_x000D_
    <p>Without align-self:</p>_x000D_
    <img src="http://i.imgur.com/NFBYJ3hs.jpg" />_x000D_
    <p>With align-self:</p>_x000D_
    <img class="align-self" src="http://i.imgur.com/NFBYJ3hs.jpg" />_x000D_
</div>

Background images sure can present data! In fact, this is often recommended where presenting visual icons is more compact and user-friendly than an equivalent list of text blurbs. Any use of image sprites can benefit from this approach.

It is quite common for hotel listings icons to display amenities. Imagine a page which listed 50 hotel and each hotel had 10 amenities. A CSS Sprite would be perfect for this sort of thing -- better user experience because it's faster. But how do you implement ALT tags for these images? Example site.

The answer is that they don't use alt text at all, but instead use the title attribute on the containing div.

HTML

<div class="hotwire-fitness" title="Fitness Centre"></div>

CSS

.hotwire-fitness {
    float: left;
    margin-right: 5px;
    background: url(/prostyle/images/new_amenities.png) -71px 0;
    width: 21px;
    height: 21px;
}

According to the W3C (see links above), the title attribute serves much of the same purpose as the alt attribute

Title

Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a "tool tip" (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context. For example, setting the attribute on a link allows user agents (visual and non-visual) to tell users about the nature of the linked resource:

alt

The alt attribute is defined in a set of tags (namely, img, area and optionally for input and applet) to allow you to provide a text equivalent for the object.

A text equivalent brings the following benefits to your website and its visitors in the following common situations:

• nowadays, Web browsers are available in a very wide variety of platforms with very different capacities; some cannot display images at all or only a restricted set of type of images; some can be configured to not load images. If your code has the alt attribute set in its images, most of these browsers will display the description you gave instead of the images
• some of your visitors cannot see images, be they blind, color-blind, low-sighted; the alt attribute is of great help for those people that can rely on it to have a good idea of what's on your page
• search engine bots belong to the two above categories: if you want your website to be indexed as well as it deserves, use the alt attribute to make sure that they won't miss important sections of your pages.

First of all you should create property with employee details in the Employee class:

public class Employee
{
    public Employee()
    {
        EmployeeDetails = new EmployeeDetails();
        EmployeeDetails.EmpID = 123;
        EmployeeDetails.EmpName = "ABC";
    }

    public EmployeeDetails EmployeeDetails { get; set; }
}

If you don't do that, you will create instance of object in Employee constructor and you lose reference to it.

In the XAML you should create instance of Employee class, and after that you can assign it to DataContext.

Your XAML should look like this:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525"
    xmlns:local="clr-namespace:SampleApplication"
   >
    <Window.Resources>
        <local:Employee x:Key="Employee" />
    </Window.Resources>
    <Grid DataContext="{StaticResource Employee}">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="200" />
        </Grid.ColumnDefinitions>

        <Label Grid.Row="0" Grid.Column="0" Content="ID:"/>
        <Label Grid.Row="1" Grid.Column="0" Content="Name:"/>
        <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding EmployeeDetails.EmpID}" />
        <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding EmployeeDetails.EmpName}" />
    </Grid>
</Window>

Now, after you created property with employee details you should binding by using this property:

Text="{Binding EmployeeDetails.EmpID}"

Based on Tim James answer and Fox32's comment, the following should check for nulls, with the assumption that two nulls are not equal.

function arrays_equal(a,b) { return !!a && !!b && !(a<b || b<a); }

> arrays_equal([1,2,3], [1,3,4])
false
> arrays_equal([1,2,3], [1,2,3])
true
> arrays_equal([1,3,4], [1,2,3])
false
> arrays_equal(null, [1,2,3])
false
> arrays_equal(null, null)
false

This should make it work in both cases

function onDateChange() {
   // Do something here
}

$('#dpd1').bind('changeDate', onDateChange);
$('#dpd1').bind('input', onDateChange);

Compact form for short commands (no 'echo'):

IF "%ID%"=="0" ( ... & ... & ... ) ELSE ^
IF "%ID%"=="1" ( ... ) ELSE ^
IF "%ID%"=="2" ( ... ) ELSE ^
REM default case...

After ^ must be an immediate line end, no spaces.

I have a similar solution to the above and it works for opening, saving, file selecting. I paste it into its own module and use in all the Access DB's I create. As the code states it requires Microsoft Office 14.0 Object Library. Just another option I suppose:

Public Function Select_File(InitPath, ActionType, FileType)
    ' Requires reference to Microsoft Office 14.0 Object Library.

    Dim fDialog As Office.FileDialog
    Dim varFile As Variant


    If ActionType = "FilePicker" Then
        Set fDialog = Application.FileDialog(msoFileDialogFilePicker)
        ' Set up the File Dialog.
    End If
    If ActionType = "SaveAs" Then
        Set fDialog = Application.FileDialog(msoFileDialogSaveAs)
    End If
    If ActionType = "Open" Then
        Set fDialog = Application.FileDialog(msoFileDialogOpen)
    End If
    With fDialog
        .AllowMultiSelect = False
        ' Disallow user to make multiple selections in dialog box
        .Title = "Please specify the file to save/open..."
        ' Set the title of the dialog box.
        If ActionType <> "SaveAs" Then
            .Filters.Clear
            ' Clear out the current filters, and add our own.
            .Filters.Add FileType, "*." & FileType
        End If
        .InitialFileName = InitPath
        ' Show the dialog box. If the .Show method returns True, the
        ' user picked a file. If the .Show method returns
        ' False, the user clicked Cancel.
        If .Show = True Then
        'Loop through each file selected and add it to our list box.
            For Each varFile In .SelectedItems
                'return the subroutine value as the file path & name selected
                Select_File = varFile
            Next
        End If
    End With
End Function

I think it will help you

string filename = String.Format("Results_{0}_{1}.xls", DateTime.Today.Month.ToString(), DateTime.Today.Year.ToString());
        if (!string.IsNullOrEmpty(GRIDVIEWNAME.Page.Title))
            filename = GRIDVIEWNAME.Page.Title + ".xls";

        HttpContext.Current.Response.Clear();

        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + filename);


        HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
        HttpContext.Current.Response.Charset = "";

        System.IO.StringWriter stringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);



        System.Web.UI.HtmlControls.HtmlForm form = new System.Web.UI.HtmlControls.HtmlForm();
        GRIDVIEWNAME.Parent.Controls.Add(form);
        form.Controls.Add(GRIDVIEWNAME);
        form.RenderControl(htmlWriter);

        HttpContext.Current.Response.Write("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />");
        HttpContext.Current.Response.Write(stringWriter.ToString());
        HttpContext.Current.Response.End();

You can use pragma related commands in sqlite like below

pragma table_info("table_name")
--Alternatively
select * from pragma_table_info("table_name")

If you require column names like id|foo|bar|age|street|address, basically your answer is in below query.

select group_concat(name,'|') from pragma_table_info("table_name")

You have two ways to fix this. The preferred way is to use:

string answer;

(instead of char). The other possible way to fix it is:

if (answer == 'y') ...

(note single quotes instead of double, representing a char constant).

Why use Regex when you can simply use the Trim() method

Text='<%# Eval("FieldDescription").ToString().Trim() %>'

OR

string test = "Testing    ";
test.Trim();

I was getting this when the app deployed. In my case, I chose "This is a full trust application" on the project security tab, and that fixed it.

I understand the ZooKeeper in general but had problems with the terms "quorum" and "split brain" so maybe I can share my findings with you (I consider myself also a layman).

Let's say we have a ZooKeeper cluster of 5 servers. One of the servers will become the leader and the others will become followers.

• These 5 servers form a quorum. Quorum simply means "these servers can vote upon who should be the leader".

• So the voting is based on majority. Majority simply means "more than half" so more than half of the number of servers must agree for a specific server to become the leader.

• So there is this bad thing that may happen called "split brain". A split brain is simply this, as far as I understand: The cluster of 5 servers splits into two parts, or let's call it "server teams", with maybe one part of 2 and the other of 3 servers. This is really a bad situation as if both "server teams" must execute a specific order how would you decide wich team should be preferred? They might have received different information from the clients. So it is really important to know what "server team" is still relevant and which one can/should be ignored.

• Majority is also the reason you should use an odd number of servers. If you have 4 servers and a split brain where 2 servers seperate then both "server teams" could say "hey, we want to decide who is the leader!" but how should you decide which 2 servers you should choose? With 5 servers it's simple: The server team with 3 servers has the majority and is allowed to select the new leader.

• Even if you just have 3 servers and one of them fails the other 2 still form the majority and can agree that one of them will become the new leader.

I realize once you think about it some time and understand the terms it's not so complicated anymore. I hope this also helps anyone in understanding these terms.

Pure string operations :):

>>> url = "http://stackoverflow.com/questions/9626535/get-domain-name-from-url"
>>> url.split("//")[-1].split("/")[0].split('?')[0]
'stackoverflow.com'
>>> url = "stackoverflow.com/questions/9626535/get-domain-name-from-url"
>>> url.split("//")[-1].split("/")[0].split('?')[0]
'stackoverflow.com'
>>> url = "http://foo.bar?haha/whatever"
>>> url.split("//")[-1].split("/")[0].split('?')[0]
'foo.bar'

That's all, folks.

How can I get the current date and time in UTC or GMT in Java?

I've fully tested it by changing the timezones on the emulator

In case someone stumbled upon this problem when working on Grails (or pure Spring) web application, here is the post that helped me:

http://forum.spring.io/forum/spring-projects/web/2491-solved-character-encoding-and-multipart-forms

To set default encoding to UTF-8 (instead of the ISO-8859-1) for multipart requests, I added the following code in resources.groovy (Spring DSL):

multipartResolver(ContentLengthAwareCommonsMultipartResolver) {
    defaultEncoding = 'UTF-8'
}

Splits an array in multiple arrays with a fixed maximum size.

public static <T extends Object> List<T[]> splitArray(T[] array, int max){

  int x = array.length / max;
  int r = (array.length % max); // remainder

  int lower = 0;
  int upper = 0;

  List<T[]> list = new ArrayList<T[]>();

  int i=0;

  for(i=0; i<x; i++){

    upper += max;

    list.add(Arrays.copyOfRange(array, lower, upper));

    lower = upper;
  }

  if(r > 0){

    list.add(Arrays.copyOfRange(array, lower, (lower + r)));

  }

  return list;
}

Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:

// create and populate an array
Integer[] arr = new Integer[11];

for(int i=0; i<arr.length; i++){
  arr[i] = i;
}

// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);

// check
for(int i=0; i<list.size(); i++){

  System.out.println("Array " + i);

  for(int j=0; j<list.get(i).length; j++){
    System.out.println("  " + list.get(i)[j]);
  }
}

Output:

Array 0
  0
  1
  2
  3
  4
Array 1
  5
  6
  7
  8
  9
Array 2
  10

This piece of code will work instead of name, email enter your form fields name

$(document).ready(function(){
  $("#form_id").submit(function(event){
    event.preventDefault();
    var name = $("input[name='name']",this).val();
    var email = $("input[name='email']",this).val();
  });
});

This is a preprocessor directive that can be used to turn on or off certain features.

It is of two types #pragma startup, #pragma exit and #pragma warn.

#pragma startup allows us to specify functions called upon program startup.

#pragma exit allows us to specify functions called upon program exit.

#pragma warn tells the computer to suppress any warning or not.

Many other #pragma styles can be used to control the compiler.

ng --version

you can watch this vidio to install the latest angular version. https://youtu.be/zqHqMAWqpD8

Go to the project's properties page, select the "Web" tab and on top (in the "Start Action" section), enter the page name in the "Specific Page" box. In your case index.aspx

Complete guide

-----------------With angular-cli--------------------------

1. Update CLI globally and locally

1. Using NPM ( make sure that you have node version 8+ )

   npm uninstall -g @angular/cli npm cache clean npm install -g @angular/cli@latest npm i @angular/cli --save

2. Using Yarn

   yarn remove @angular/cli yarn global add @angular/cli yarn add @angular/cli

2.Update dependencies

ng update @angular/cli
ng update @angular/core
ng update @angular/material
ng update rxjs

Angular 6 now depends on TypeScript 2.7 and RxJS 6

Normally that would mean that you have to update your code everywhere RxJS imports and operators are used, but thankfully there’s a package that takes care of most of the heavy lifting:

npm i -g rxjs-tslint 

//or using yarn

yarn global add rxjs-tslint

Then you can run rxjs-5-to-6-migrate

rxjs-5-to-6-migrate -p src/tsconfig.app.json

finally remove rxjs-compat

npm uninstall rxjs-compat

// or using Yarn

yarn remove rxjs-compat

Refer to this link https://alligator.io/angular/angular-6/

-------------------Without angular-cli-------------------------

So you have to manually update your package.json file.

Then run

 npm update
 npm install --save rxjs-compat
 npm i -g rxjs-tslint
 rxjs-5-to-6-migrate -p src/tsconfig.app.json

Edit: Out of date answer, ECMAScript 2015 (ES6) standard javascript has a Map implementation, read here for more info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

var map = new Object(); // or var map = {};
map[myKey1] = myObj1;
map[myKey2] = myObj2;

function get(k) {
    return map[k];
}

//map[myKey1] == get(myKey1);

try:

%matplotlib notebook

see jakevdp reply here

EDIT for JupyterLab users:

Follow the instructions to install jupyter-matplotlib

Then the magic command above is no longer needed, as in the example:

# Enabling the `widget` backend.
# This requires jupyter-matplotlib a.k.a. ipympl.
# ipympl can be install via pip or conda.
%matplotlib widget
# aka import ipympl

import matplotlib.pyplot as plt

plt.plot([0, 1, 2, 2])
plt.show()

Finally, note Maarten Breddels' reply; IMHO ipyvolume is indeed very impressive (and useful!).
