Responding because this answer came up first for search when I was having the same issue:

[08S01][unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist

MSSQL named instances have to be configured properly without setting the port. (documentation on the freetds config says set instance or port NOT BOTH)

freetds.conf

[Name]
host = Server.com
instance = instance_name
#port = port is found automatically, don't define explicitly
tds version = 8.0
client charset = UTF-8

And in odbc.ini just because you can set Port, DON'T when you are using a named instance.

I had the same problem but also wanted to get the content of the file (after the YAML front-matter).

This is the best solution I have found:

if (md = contents.match(/^(?<metadata>---\s*\n.*?\n?)^(---\s*$\n?)/m))
  self.contents = md.post_match
  self.metadata = YAML.load(md[:metadata])
end

A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.

If you want to control the width of your data, then you could use the width sub-specifiers in the printf format string. Eg. :

printf("%5d", 2);

It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.

If you want complete control, you'll probably have to implement it yourself.

You need ImageMagick and GhostScript

<?php
$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

The [0] means page 1.

Java 8 support a more declarative approach to iteration, in that we specify the result we want rather than how to compute it. Benefits of the new approach are that it can be more readable, less error prone.

public static void mapRemove() {

    Map<Integer, String> map = new HashMap<Integer, String>() {
        {
            put(1, "one");
            put(2, "two");
            put(3, "three");
        }
    };

    map.forEach( (key, value) -> { 
        System.out.println( "Key: " + key + "\t" + " Value: " + value );  
    }); 

    map.keySet().removeIf(e->(e>2)); // <-- remove here

    System.out.println("After removing element");

    map.forEach( (key, value) -> { 
        System.out.println( "Key: " + key + "\t" + " Value: " + value ); 
    });
}

And result is as follows:

Key: 1   Value: one
Key: 2   Value: two
Key: 3   Value: three
After removing element
Key: 1   Value: one
Key: 2   Value: two

I'm an Eclipse/Android beginner as well, but hopefully my simple debugging process can help...

You set breakpoints in Eclipse by right-clicking next to the line you want to break at and selecting "Toggle Breakpoint". From there you'll want to select "Debug" rather than the standard "Run", which will allow you to step through and so on. Use the filters provided by LogCat (referenced in your tutorial) so you can target the messages you want rather than wading through all the output. That will (hopefully) go a long way in helping you make sense of your errors.

As for other good tutorials, I was searching around for a few myself, but didn't manage to find any gems yet.

It could be that your default format doesn't match the file extension. You should specify the file format along with the filename, making sure the format matches the extension:

With someWorkbook
.SaveAs "C:\someDirector\Awesome.xlsm", fileformat:=xlOpenXMLWorkbookMacroEnabled
End With

OTOH, I don't see an extension on your .SaveAs filename. Maybe you need to supply one when doing this programmatically. That makes sense--not having to supply an extension from the GUI interface is convenient, but we programmers are expected to write unambiguous code. I suggest adding the extension and the matching format. See this msdn page for a list of file formats. To be honest, I don't recognize a lot o the descripions.

xlExcel8 = 56 is the .xls format

xlExcel12 = 50 is the .xlsb format

xlOpenXMLWorkbook = 51 is the .xlsx format

xlOpenXMLWorkbookMacroEnabled = 52 is the .xlsm format

xlWorkbookDefault is also listed with a value of 51, which puzzles me since I thought the default format could be changed.

The following categories of variables are classified as initially unassigned:

• Instance variables of initially unassigned struct variables.
• Output parameters, including the this variable of struct instance constructors.
• Local variables , except those declared in a catch clause or a foreach statement.

The following categories of variables are classified as initially assigned:

• Static variables.
• Instance variables of class instances.
• Instance variables of initially assigned struct variables.
• Array elements.
• Value parameters.
• Reference parameters.
• Variables declared in a catch clause or a foreach statement.

employees.sort(key = lambda x:x[1])
employees.sort(key = lambda x:x[0])

We can also use .sort with lambda 2 times because python sort is in place and stable. This will first sort the list according to the second element, x[1]. Then, it will sort the first element, x[0] (highest priority).

employees[0] = Employee's Name
employees[1] = Employee's Salary

This is equivalent to doing the following: employees.sort(key = lambda x:(x[0], x[1]))

This may sound like the long way around, but you may want to look at using Excel to generate INSERT SQL code that you can past into Query Analyzer to create your table.

Works well if you cant use the wizards because the excel file isn't on the server

Cardview is a bit coy. I had list of colors in my structure and Model is like

class ModelColor : Serializable {

var id: Int? = 0
var title: String? = ""
var color: Int? = 0// HERE IS THE COLOR FIELD WE WILL USE

constructor(id: Int?, title: String?, color: Int?) {
    this.id = id
    this.title = title
    this.color = color
}

}

load the model with color, last item on constructure taking from R.color

 list.add(ModelColor(2, getString(R.string.orange), R.color.orange_500))

and finaly you can setBackgriundResource

 cv_add_goal_choose_color.setBackgroundResource(color)

You're getting None because list.sort() it operates in-place, meaning that it doesn't return anything, but modifies the list itself. You only need to call a.sort() without assigning it to a again.

There is a built in function sorted(), which returns a sorted version of the list - a = sorted(a) will do what you want as well.

Another way to do this is by using event listeners, here how you use them:

document.addEventListener("DOMContentLoaded", function() {
  you_function(...);
});

Explanation:

DOMContentLoaded It means when the DOM Objects of the document are fully loaded and seen by JavaScript, also this could have been "click", "focus"...

function() Anonymous function, will be invoked when the event occurs.

    var GDNUtils = {};

GDNUtils.loadJquery = function () {
    var checkjquery = window.jQuery && jQuery.fn && /^1\.[3-9]/.test(jQuery.fn.jquery);
    if (!checkjquery) {

        var theNewScript = document.createElement("script");
        theNewScript.type = "text/javascript";
        theNewScript.src = "http://code.jquery.com/jquery.min.js";

        document.getElementsByTagName("head")[0].appendChild(theNewScript);

        // jQuery MAY OR MAY NOT be loaded at this stage


    }
};



GDNUtils.searchJsonValue = function (jsonData, keytoSearch, valuetoSearch, keytoGet) {
    GDNUtils.loadJquery();
    alert('here' + jsonData.length.toString());
    GDNUtils.loadJquery();

    $.each(jsonData, function (i, v) {

        if (v[keytoSearch] == valuetoSearch) {
            alert(v[keytoGet].toString());

            return;
        }
    });



};




GDNUtils.searchJson = function (jsonData, keytoSearch, valuetoSearch) {
    GDNUtils.loadJquery();
    alert('here' + jsonData.length.toString());
    GDNUtils.loadJquery();
    var row;
    $.each(jsonData, function (i, v) {

        if (v[keytoSearch] == valuetoSearch) {


            row  = v;
        }
    });

    return row;



}

Just another Eclipse plugin for *.properties files:

You could use groupby to split the DataFrame into subgroups according to the color:

for key, grp in df.groupby(['color']):

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.read_table('data', sep='\s+')
fig, ax = plt.subplots()

for key, grp in df.groupby(['color']):
    ax = grp.plot(ax=ax, kind='line', x='x', y='y', c=key, label=key)

plt.legend(loc='best')
plt.show()

yields

I was just reading this article, and it says:

Important: the order of the video files is vital; Chrome currently has a bug in which it will not autoplay a .webm video if it comes after anything else.

So it looks like your problem would be solved if you put the .webm first in your list of sources. Hope that helps.

No there's not and developers still don't know why google doesn't pay attention to this request!

As you can see in this link it's one of the most popular issues with many stars in google code but still no response from google! You can also add stars to this issue, maybe google hears that!

I know the OP was asking about doing the export from the command line, but just in case this is helpful to anyone else out there...

You could just let Eclipse (plus one of the plugins discussed here) do the work for you.

Obviously, downloading Eclipse just for doing a single export is overkill, but if you are already using it for development, you can also do an svn export simply from your IDE's context menu when browsing an SVN repository.

Advantages:

• easier for those not so familiar with using SVN at the command-line level (but you can learn about what happens at the command-line level by looking at the SVN console with a range of commands)
• you'd already have your SVN details set up and wouldn't have to worry about authenticating, etc.
• you don't have to worry about mistyping the URL, or remembering the order of parameters
• you can specify in a dialog which directory you'd like to export to
• you can specify in a dialog whether you'd like to export from TRUNK/HEAD or use a specific revision

import numpy as np
x = np.array([[1,2,3], [4,5,6]])
y = np.array([[-1, 2, 0], [-2, 5, 1]])

x*y
Out: 
array([[-1,  4,  0],
       [-8, 25,  6]])

%timeit x*y
1000000 loops, best of 3: 421 ns per loop

np.multiply(x,y)
Out: 
array([[-1,  4,  0],
       [-8, 25,  6]])

%timeit np.multiply(x, y)
1000000 loops, best of 3: 457 ns per loop

Both np.multiply and * would yield element wise multiplication known as the Hadamard Product

%timeit is ipython magic

You are mixing razor and aspx syntax,if your view engine is razor just do this:

<button class="btn btn-info" type="button" id="addressSearch"   
          onclick="location.href='@Url.Action("List", "Search")'">

Those pesky black dots you are referencing to are called bullets.

They are pretty simple to remove, just add this line to your css:

ul {
    list-style-type: none;
}

Hope this helps

You can solve this in two steps:

STEP 1: Open the Command prompt and type netstat -a -o -f and press enter (the above command will show all the processes running on your machine) https://i.stack.imgur.com/m66JN.png

STEP 2: Type TASKILL /F /PID 4036 (where F stands for force and PID stands for parent Id and 4036 stands for process id of 8080, here I am using some random number) https://i.stack.imgur.com/Co5Tg.png

Few times when you are trying to kill process it will throw an exception telling that access is denied as shown in the above screenshot, at that point of time you are supposed to open command prompt as run as administrator https://i.stack.imgur.com/JwZTv.png

Then come back to eclipse clean the project and then try to run the project

Ive been looking for an nice select dropdown for some time now and I found a good one. So im just gonna leave it here. Its called bootsrap-select

here's the link. check it out. it has editable dropdowns, combo drop downs and more. And its a breeze to add to your project.

If the link dies just search for bootstrap-select by silviomoreto.github.io. This is better because its a normal select tag

Update to the answer

    // Get stack trace for the exception with source file information
    var st = new StackTrace(ex, true);
    // Get the top stack frame
    var frame = st.GetFrame(st.FrameCount-1);
    // Get the line number from the stack frame
    var line = frame.GetFileLineNumber();

You can set properties from JavaScript.

document.getElementById("foo").myAttri = "myVal"

try to do this in the behind code

   public diagboxclass()
   {
         List<object> list = new List<object>();
         list = GetObjectList();
         Imported.ItemsSource = null;
         Imported.ItemsSource = list;
   }

Also be sure your list is effectively populated and as mentioned by Blindmeis, never use words that already are given a function in c#.

For those times when you need to use jquery to set !important properties, here is a plugin I build that will allow you to do so.

$.fn.important = function(key, value) {
    var q = Object.assign({}, this.style)
    q[key] = `${value} !important`;
    $(this).css("cssText", Object.entries(q).filter(x => x[1]).map(([k, v]) => (`${k}: ${v}`)).join(';'));
};

$('div').important('color', 'red');

You can make a workaround but this will remove the fade from all the page. The modal will popup like Facebook popups. After opening the modal try:

 $('.modal-backdrop').removeClass('modal-backdrop');

For those who are writing Eclipse plugins and want to include the source... in the feature ExportWizard there is an option for including the source:

A single listening port can accept more than one connection simultaneously.

There is a '64K' limit that is often cited, but that is per client per server port, and needs clarifying.

Each TCP/IP packet has basically four fields for addressing. These are:

source_ip source_port destination_ip destination_port
<----- client ------> <--------- server ------------>

Inside the TCP stack, these four fields are used as a compound key to match up packets to connections (e.g. file descriptors).

If a client has many connections to the same port on the same destination, then three of those fields will be the same - only source_port varies to differentiate the different connections. Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K.

However, multiple clients can each have up to 64K connections to some server's port, and if the server has multiple ports or either is multi-homed then you can multiply that further.

So the real limit is file descriptors. Each individual socket connection is given a file descriptor, so the limit is really the number of file descriptors that the system has been configured to allow and resources to handle. The maximum limit is typically up over 300K, but is configurable e.g. with sysctl.

The realistic limits being boasted about for normal boxes are around 80K for example single threaded Jabber messaging servers.

How about:

if (regexMatcher.find()) {
    resultString = regexMatcher.replaceAll(
            String.valueOf(3 * Integer.parseInt(regexMatcher.group(1))));
}

To get the first match, use #find(). After that, you can use #group(1) to refer to this first match, and replace all matches by the first maches value multiplied by 3.

And in case you want to replace each match with that match's value multiplied by 3:

    Pattern p = Pattern.compile("(\\d{1,2})");
    Matcher m = p.matcher("12 54 1 65");
    StringBuffer s = new StringBuffer();
    while (m.find())
        m.appendReplacement(s, String.valueOf(3 * Integer.parseInt(m.group(1))));
    System.out.println(s.toString());

You may want to look through Matcher's documentation, where this and a lot more stuff is covered in detail.

Extending @RobBednark's solution to a specific Windows + PuTTY scenario, you can do so:

1. Generate SSH key pair with PuTTYgen (following Manually generating your SSH key in Windows), saving it to a PPK file;

2. With the context menu in Windows Explorer, choose Edit with PuTTYgen. It will prompt for a password.

If you type the wrong password, it will just prompt again.

Note, if you like to type, use the following command on a folder that contains the PPK file: puttygen private-key.ppk -y.

You can keep it disabled as desired, and then remove the disabled attribute before the form is submitted.

$('#myForm').submit(function() {
    $('select').removeAttr('disabled');
});

Note that if you rely on this method, you'll want to disable it programmatically as well, because if JS is disabled or not supported, you'll be stuck with the disabled select.

$(document).ready(function() {
    $('select').attr('disabled', 'disabled');
});

another important point is that Random.nextInt(n) is repeatable since you can create two Random object with the same seed. This is not possible with Math.random().

You have to create your own player that interfaces with the HTML5 audio element. This tutorial will help http://alexkatz.me/html5-audio/building-a-custom-html5-audio-player-with-javascript/

ssh-keygen isn't a windows executable.
You can use PuttyGen (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) for example to create a key

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

<Button x:Name="btnBack" Grid.Row="2" Width="300"
                        Click="btnBack_Click">
                <Button.Template>
                    <ControlTemplate>
                        <Border CornerRadius="10" Background="#463190">
                            <TextBlock Text="Retry" Foreground="White" 
                                       HorizontalAlignment="Center"                                           
                                       Margin="0,5,0,0"
                                       Height="40"
                                       FontSize="20"></TextBlock>
                        </Border>
                    </ControlTemplate>
                </Button.Template>
            </Button>

This is working fine for me.

The best way to access files from resource folder inside a jar is it to use the InputStream via getResourceAsStream. If you still need a the resource as a file instance you can copy the resource as a stream into a temporary file (the temp file will be deleted when the JVM exits):

public static File getResourceAsFile(String resourcePath) {
    try {
        InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
        if (in == null) {
            return null;
        }

        File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
        tempFile.deleteOnExit();

        try (FileOutputStream out = new FileOutputStream(tempFile)) {
            //copy stream
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = in.read(buffer)) != -1) {
                out.write(buffer, 0, bytesRead);
            }
        }
        return tempFile;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

Using JDBC in Java:

    String quer="SELECT * FROM sample2 where 1=2";
    
    Statement st=con.createStatement();
    ResultSet rs=st.executeQuery(quer);
    ResultSetMetaData rsmd = rs.getMetaData();
    int NumOfCol=0;
    NumOfCol=rsmd.getColumnCount();
    System.out.println("Query Executed!! No of Colm="+NumOfCol);

@EnableWebMvc annotation on config class resolved my problem. (Spring 5, no web.xml, initialized by AbstractAnnotationConfigDispatcherServletInitializer)

It's included because your minimum SDK version is set to 10. The ActionBar was introduced in API 11. Eclipse adds it automatically so your app can look more consistent throughout the spectrum of all android versions you are supporting.

Entering: /usr/bin/gcc worked for me.

Going back to the original question (4 years later), rather than rebuilding your own section header, iOS can simply call you (with willDisplayHeaderView:forSection:) right after it's built the default one. For example, I wanted to add a graph button on right edge of section header:

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    UITableViewHeaderFooterView * header = (UITableViewHeaderFooterView *) view;
    if (header.contentView.subviews.count >  0) return; //in case of reuse
    CGFloat rightEdge = CGRectGetMaxX(header.contentView.bounds);
    UIButton * button = [[UIButton alloc] initWithFrame:CGRectMake(rightEdge - 44, 0, 44, CGRectGetMaxY(header.contentView.bounds))];
    [button setBackgroundImage:[UIImage imageNamed:@"graphIcon"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(graphButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [view addSubview:button];
}

I think you can leverage the [Zip File System Provider][1] to achieve this. When using FileSystems.newFileSystem it looks like you can treat the objects in that ZIP as a "regular" file.

In the linked documentation above:

Specify the configuration options for the zip file system in the java.util.Map object passed to the FileSystems.newFileSystem method. See the [Zip File System Properties][2] topic for information about the provider-specific configuration properties for the zip file system.

Once you have an instance of a zip file system, you can invoke the methods of the [java.nio.file.FileSystem][3] and [java.nio.file.Path][4] classes to perform operations such as copying, moving, and renaming files, as well as modifying file attributes.

The documentation for the jdk.zipfs module in [Java 11 states][5]:

The zip file system provider treats a zip or JAR file as a file system and provides the ability to manipulate the contents of the file. The zip file system provider can be created by [FileSystems.newFileSystem][6] if installed.

Here is a contrived example I did using your example resources. Note that a .zip is a .jar, but you could adapt your code to instead use classpath resources:

Setup

cd /tmp
mkdir -p x/y/z
touch x/y/z/{a,b,c}.html
echo 'hello world' > x/y/z/d
zip -r example.zip x

There is no need to do two checks, why not just check for count = 3:

GROUP BY meetingID
HAVING COUNT(caseID) = 3

If you want to use the multiple checks, then you can use:

GROUP BY meetingID
HAVING COUNT(caseID) > 2
 AND COUNT(caseID) < 4

Using command line:

python -c "import scipy; print(scipy.__version__)"

    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    if textField==yourTextFieldOutlet {
                if(CharacterSet.decimalDigits.isSuperset(of: CharacterSet(charactersIn: yourTextFieldOutlet.text!))){
//if numbers only, then your code here
                }
                else{
                showAlert(title: "Error",message: "Enter Number only",type: "failure")
                }
            }
    return true
    }

So here is the controller code.

public IActionResult AddURLTest()
{
    return ViewComponent("AddURL");
}

You can load it using JQuery load method.

$(document).ready (function(){
    $("#LoadSignIn").click(function(){
        $('#UserControl').load("/Home/AddURLTest");
    });
});

@files is an existing array

my @new_values =  grep(/^2[\d].[\d][A-za-z]?/,@files);

print join("\n", @new_values);

print "\n";

/^2[\d].[\d][A-za-z]?/ = vaues starting from 2 here you can put any regular expression

There is only one public signature allowed for each controller method. If you try to overload it, it will compile, but you're getting the run-time error you've experienced.

If you're not willing to use different verbs (like the [HttpGet] and [HttpPost] attributes) to differentiate overloaded methods (which will work), or change the routing, then what remains is that you can either provide another method with a different name, or you can dispatch inside of the existing method. Here's how I did it:

I once came into a situation where I had to maintain backwards compatibility. The original method expected two parameters, but the new one had only one. Overloading the way I expected did not work because MVC didn't find the entry point any more.

To solve that, I did the following:

1. Changed the 2 overloaded action methods from public to private

2. Created one new public method which contained "just" 2 string parameters. That one acted as a dispatcher, i.e.:

   public ActionResult DoSomething(string param1, string param2)
   {
       if (string.IsNullOrEmpty(param2))
       {
           return DoSomething(ProductName: param1);
       }
       else
       {
           int oldId = int.Parse(param1);
           return DoSomething(OldParam: param1, OldId: oldId);
       }
   }
   
   
   private ActionResult DoSomething(string OldParam, int OldId)
   {
       // some code here
       return Json(result);
   }
   
   
   private ActionResult DoSomething(string ProductName)
   {
       // some code here
       return Json(result);
   }
   

Of course, this is a hack and should be refactored later. But for the time being, it worked for me.

You can also create a dispatcher like:

public ActionResult DoSomething(string action, string param1, string param2)
{
    switch (action)
    {
        case "update":
            return UpdateAction(param1, param2);
        case "remove":
            return DeleteAction(param1);
    }
}

You can see, that UpdateAction needs 2 parameters, while DeleteAction just needs one.

1. go to the master branch our-team

   • git checkout our-team

2. pull all the new changes from our-team branch

   • git pull

3. go to your branch featurex

   • git checkout featurex

4. merge the changes of our-team branch into featurex branch

   • git merge our-team
   • or git cherry-pick {commit-hash} if you want to merge specific commits

5. push your changes with the changes of our-team branch

   • git push

Note: probably you will have to fix conflicts after merging our-team branch into featurex branch before pushing

SIDENOTE: I had a lot of fun trying to get this into my iPad after that. It worked however. Using Snow Leopard + Xcode 4.2 + iPad with IOS 5.1.1 :) - I used the iPhone configuration utility to get the app into the ipad (you have to add the app, then click on the device, then click "install" behind the app you just added in the "application library" of iphone configuration utility) and had to create a Distribution Provisioning Profile and get the WWDR certificate and finally change the build settings in Xcode after all the certificates were in place. See here

But after much fun I am now looking at my first app on my iPad :) - btw, for getting apps into the app store you need to create a app store Distribution Provisioning Profile, while for ad hoc installs like these you create an ad hoc one. There is a bit more to it, but I think these are the most important and tricky steps. Enjoy.

PS. Just remembered that you also have to set the build type (top left of Xcode) to "iOS device", otherwise it will never sign your application. So the path name above only has limited value: yes, it will have the .app file in it, but no you can't upload it (at least not using the iPhone configuration utility) since it is not code signed - you will get an "Could not copy validate signature" error. So change it to "iOS device" and build (remember to select the right certificates in the build section of Xcode as per the url info above). In that same build section, you can also set the "Installation Build Products Location" to a different path, so that you can determine where the .app (the one that is properly code signed) ends up.

$('input[type=text], textarea').css({width: '90%'});

That uses standard CSS selectors, jQuery also has a set of pseudo-selector filters for various form elements, for example:

$(':text').css({width: '90%'});

will match all <input type="text"> elements. See Selectors documentation for more info.

If you want to call your activity, just use this . You use the getActivity method when you are inside a fragment.

Boost contains cstdint.hpp header file with the types you are looking for: http://www.boost.org/doc/libs/1_36_0/boost/cstdint.hpp

Look for any DDL operation in the script. Maybe the user does not have access rights to run changes.

In my case it was SET IDENTITY_INSERT tblTableName ON

You can either add db_ddladmin for the whole database or for just the table to solve this issue (or change the script)

-- give the non-ddladmin user INSERT/SELECT as well as ALTER:
GRANT ALTER, INSERT, SELECT ON dbo.tblTableName TO user_name;

On Windows 10 using the terminal under VS Code I got a prompt for "git@gitlab's password:" when trying to:

git push -u origin --all

I had established my ssh credentials in windows and in gitlab but I had used Windows 10 bash key-gen to do so. The solution then was to invoke bash in VS code terminal and then issue the command again.

bash
git push -u origin --all

It succeeded.

To avoid having to use bash/git manually, I then put a symlink between the windows .ssh/id_rsa and the bash shell .ssh/id_rsa:

C:\Users\bruce\.ssh>mklink id_rsa C:\Users\bruce\AppData\Local\lxss\home\bruce\.ssh\id_rsa

VS Code Git menu actions (push, pull, etc.) now worked with gitlab

You will need to make sure about timeouts between you and the file. In this case PHP and Curl.

To tell Curl to never timeout when a transfer is still active, you need to set CURLOPT_TIMEOUT to 0, instead of 1000.

curl_setopt($ch, CURLOPT_TIMEOUT, 0);

In PHP, again, you must remove time limits or PHP it self (after 30 seconds by default) will kill the script along Curl's request. This alone should fix your issue.
In addition, if you require data integrity, you could add a layer of security by using ignore_user_abort:

# The maximum execution time, in seconds. If set to zero, no time limit is imposed.
set_time_limit(0);

# Make sure to keep alive the script when a client disconnect.
ignore_user_abort(true);

A client disconnection will interrupt the execution of the script and possibly damaging data,
eg. non-transitional database query, building a config file, ecc., while in your case it would download a partial file... and you might, or not, care about this.

Answering this old question because this thread is at the top on engine searches for CURL_TIMEOUT.

myfun(){
    [ -d "$1" ]
}
if myfun "path"; then
    echo yes
fi
# or
myfun "path" && echo yes

This answer relates to modern setups (TypeScript 2.x, Webpack > 2.x)

You don't need to install @types/node (which is all of Node.js types and is irrelevant for front-end code, actually complicating things such as setTimout different return values, etc..

You do need to install @types/webpack-env

npm i -D @types/webpack-env

which gives the runtime signatures that Webpack has (including require, require.ensure, etc.)

Also make sure that your tsconfig.json file has no set 'types' array -> which will make it pickup all type definitions in your node_modules/@types folder.

If you want to restrict search of types you can set the typeRoot property to node_modules/@types.

If the formulas are identical you can use Find and Replace with Match entire cell contents checked and Look in: Formulas. Select the range, go into Find and Replace, make your entries and `Replace All.

Or do you mean that there are several formulas with this same form, but different cell references? If so, then one way to go is a regular expression match and replace. Regular expressions are not built into Excel (or VBA), but can be accessed via Microsoft's VBScript Regular Expressions library.

The following function provides the necessary match and replace capability. It can be used in a subroutine that would identify cells with formulas in the specified range and use the formulas as inputs to the function. For formulas strings that match the pattern you are looking for, the function will produce the replacement formula, which could then be written back to the worksheet.

Function RegexFormulaReplace(formula As String)
    Dim regex As New RegExp
    regex.Pattern = "=\(\(([A-Z]+\d+)-([A-Z]+\d+)\)/([A-Z]+\d+)\)"
'   Test if a match is found
    If regex.Test(formula) = True Then
        RegexFormulaReplace = regex.Replace(formula, "=(EXP((LN($1/$2)/14.32))-1")
    Else
        RegexFormulaReplace = CVErr(xlErrValue)
    End If
    Set regex = Nothing
End Function

In order for the function to work, you would need to add a reference to the Microsoft VBScript Regular Expressions 5.5 library. From the Developer tab of the main ribbon, select VBA and then References from the main toolbar. Scroll down to find the reference to the library and check the box next to it.

you should use :

ln -s /home/jake/doc/test/2000/something xxx

Let us say your jsfunctions.js file has a function "display" and this file is stored in C:/Scripts/Jsfunctions.js

jsfunctions.js

var display = function(name) {
print("Hello, I am a Javascript display function",name);
return "display function return"
}

Now, in your java code, I would recommend you to use Java8 Nashorn. In your java class,

import java.io.FileNotFoundException;
import java.io.FileReader;

import javax.script.Invocable;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

class Test {
public void runDisplay() {
ScriptEngine engine = new ScriptEngineManager().getEngineByName("nashorn");
try {
  engine.eval(new FileReader("C:/Scripts/Jsfunctions.js"));
  Invocable invocable = (Invocable) engine;
  Object result;
  result = invocable.invokeFunction("display", helloWorld);
  System.out.println(result);
  System.out.println(result.getClass());
  } catch (FileNotFoundException | NoSuchMethodException | ScriptException e) {
    e.printStackTrace();
    }
  }
}

Note: Get the absolute path of your javascript file and replace in FileReader() and run the java code. It should work.

The best superuser role would be the root.The Syntax is:

use admin

db.createUser(
{
    user: "root",
    pwd: "password",
    roles: [ "root" ]
})

For more details look at built-in roles.

Hope this helps !!!

You can't actually put it inside the text box unfortunately, only make it look like its inside it, which unfortunately means some css is needed :P

Theory is wrap the input in a div, take all the borders and backgrounds off the input, then style the div up to look like the box. Then, drop in your button after the input box in the code and the jobs a good'un.

Once you've got it to work anyway ;)

assuming you want to find a value in a numpy array, I guess something like this might work:

Numpy.where(arr=="value")[0]

In my case, I solved it changing the @Id field type from long to Long.

You can't set the field having data-type "text". Only because of that thing you are getting this error. Try to change the data-type with int

Hey check this, works for me... hope it work for u too

If list item contains ImageButton

Problem: OnItemClickListener just doesn’t repond any at all!

Reason: No idea

Solution: in code, set ImageButton's focus to “false”

1: ImageButton button = (ImageButton) convertView.findViewById(R.id.imageButton);

2: button.setFocusable(false);

Alright this is very late however I've discovered that if you add a List View under your edit text then the keyboard will move all layouts under that edittext without moving the ListView

<EditText
android:id="@+id/et"
android:layout_height="match_parent"
android:layout_width="match_parent"



/>

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"//can make as 1dp
    android:layout_below="@+id/et" // set to below editext
    android:id="@+id/view"
    >
**<any layout**

This is the only solution that worked for me.

I write this function

def larger(x, than=0):
    if not x or min(x) > than:
        return True
    return False

Then

print larger([5, 6, 7], than=5)  # False
print larger([6, 7, 8], than=5)  # True
print larger([], than=5)  # True
print larger([6, 7, 8, None], than=5)  # False

Empty list on min() will raise ValueError. So I added if not x in condition.

Here's three ways to do it.

public enum Months {
    JAN(1), FEB(2), MAR(3), APR(4), MAY(5), JUN(6), JUL(7), AUG(8), SEP(9), OCT(10), NOV(11), DEC(12);


    int monthOrdinal = 0;

    Months(int ord) {
        this.monthOrdinal = ord;
    }

    public static Months byOrdinal2ndWay(int ord) {
        return Months.values()[ord-1]; // less safe
    }

    public static Months byOrdinal(int ord) {
        for (Months m : Months.values()) {
            if (m.monthOrdinal == ord) {
                return m;
            }
        }
        return null;
    }
    public static Months[] MONTHS_INDEXED = new Months[] { null, JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC };

}




import static junit.framework.Assert.assertEquals;

import org.junit.Test;

public class MonthsTest {

@Test
public void test_indexed_access() {
    assertEquals(Months.MONTHS_INDEXED[1], Months.JAN);
    assertEquals(Months.MONTHS_INDEXED[2], Months.FEB);

    assertEquals(Months.byOrdinal(1), Months.JAN);
    assertEquals(Months.byOrdinal(2), Months.FEB);


    assertEquals(Months.byOrdinal2ndWay(1), Months.JAN);
    assertEquals(Months.byOrdinal2ndWay(2), Months.FEB);
}

}

Since May 23, 2018 update, when you're using a firebase dependency, you must include the firebase-core dependency, too.

If adding it, you still having the error, try to update the gradle plugin in your gradle-wrapper.properties to 4.5 version:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip

and resync the project.

I see the picture, and all your classes are in the same package. So you don't have to import, you can create a new instance without the import sentence.

In combination with try method, to support nil value:

'string'.try(:upcase)
'string'.try(:capitalize)
'string'.try(:titleize)

This should work

<option *ngFor="let title of titleArray" 
    [value]="title.Value" 
    [attr.selected]="passenger.Title==title.Text ? true : null">
  {{title.Text}}
</option>

I'm not sure the attr. part is necessary.

Angular 7,8 fix is in app.module.ts

import {APP_BASE_HREF} from '@angular/common';

inside @NgModule add

providers: [{provide: APP_BASE_HREF, useValue: '/'}]

$dateString = '08/04/2010 22:15:00';
$dateObject = new DateTime($dateString);
echo $dateObject->format('h:i A');

This Issue is solved in version Angular 2.0.0-rc.4, respectively in forms.

Include "@angular/forms": "0.2.0" in package.json.

Then extend your bootstrap in main. Relevant part:

...
import { AppComponent } from './app/app.component';
import { disableDeprecatedForms, provideForms } from '@angular/forms';

bootstrap(AppComponent, [
    disableDeprecatedForms(),
    provideForms(),
    appRouterProviders
]);

I have this in .html and works perfectly: value: {{buildTool}}

<form action="">
    <input type="radio" [(ngModel)]="buildTool" name="buildTool" value="gradle">Gradle <br>
    <input type="radio" [(ngModel)]="buildTool" name="buildTool" value="maven">Maven
</form>

foreach (DataGridViewRow row in dataGridView1.Rows)
        {
            for (int i = 0; i < dataGridView1.Columns.Count; i++)
            {
                String header = dataGridView1.Columns[i].HeaderText;
                //String cellText = row.Cells[i].Text;
                DataGridViewColumn column = dataGridView1.Columns[i]; // column[1] selects the required column 
                column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells; // sets the AutoSizeMode of column defined in previous line
                int colWidth = column.Width; // store columns width after auto resize           
                colWidth += 50; // add 30 pixels to what 'colWidth' already is
                this.dataGridView1.Columns[i].Width = colWidth; // set the columns width to the value stored in 'colWidth'
            }
        }

To give a detailed answer to question 3: yes, there are (rare) occasions when you might call the destructor explicitly, in particular as the counterpart to a placement new, as dasblinkenlight observes.

To give a concrete example of this:

#include <iostream>
#include <new>

struct Foo
{
    Foo(int i_) : i(i_) {}
    int i;
};

int main()
{
    // Allocate a chunk of memory large enough to hold 5 Foo objects.
    int n = 5;
    char *chunk = static_cast<char*>(::operator new(sizeof(Foo) * n));

    // Use placement new to construct Foo instances at the right places in the chunk.
    for(int i=0; i<n; ++i)
    {
        new (chunk + i*sizeof(Foo)) Foo(i);
    }

    // Output the contents of each Foo instance and use an explicit destructor call to destroy it.
    for(int i=0; i<n; ++i)
    {
        Foo *foo = reinterpret_cast<Foo*>(chunk + i*sizeof(Foo));
        std::cout << foo->i << '\n';
        foo->~Foo();
    }

    // Deallocate the original chunk of memory.
    ::operator delete(chunk);

    return 0;
}

The purpose of this kind of thing is to decouple memory allocation from object construction.

This is a known bug, you can work it around with a hack:

Open up site-packages/requests/packages/urllib3/connectionpool.py (or otherwise just make a local copy of requests inside your own project), and change the block that says:

def connect(self):
    # Add certificate verification
    sock = socket.create_connection((self.host, self.port), self.timeout)

    # Wrap socket using verification with the root certs in
    # trusted_root_certs
    self.sock = ssl_wrap_socket(sock, self.key_file, self.cert_file,
                                cert_reqs=self.cert_reqs,
                                ca_certs=self.ca_certs,
                                server_hostname=self.host,
                                ssl_version=self.ssl_version)

to:

def connect(self):
    # Add certificate verification
    sock = socket.create_connection((self.host, self.port), self.timeout)

    # Wrap socket using verification with the root certs in
    # trusted_root_certs
    self.sock = ssl_wrap_socket(sock, self.key_file, self.cert_file,
                                cert_reqs=self.cert_reqs,
                                ca_certs=self.ca_certs,
                                server_hostname=self.host,
                                ssl_version=ssl.PROTOCOL_TLSv1)

Otherwise, I suppose there's an override somewhere which is less hacky, but I couldn't find one with a few glances.

NOTE: On a sidenote, requests from PIP (1.0.4) on a MacOS just works with the URL you provided.

I had the same error.

My filename was jpaContext.xml and it was placed in src/main/resources. I specified param value="classpath:/jpaContext.xml".

Finally I renamed the file to applicationContext.xml and moved it to the WEB-INF directory and changed param value to /WEB-INF/applicationContext.xml, then it worked!

Import division from future library like this:

    {
        string text = File.ReadAllText(filePath);
        browser.ScriptErrorsSuppressed = true;

        browser?.Document?.OpenNew(false);
        browser?.Document?.Write(text);
        return browser.Document?.Body?.InnerText;
        //return browser.Document?.Body?.InnerText.Replace(Environment.NewLine, "<br />");
    }

You can also use the Cookies API and do:

browser.cookies.set({
  url: 'example.com',
  name: 'HelloWorld',
  value: 'HelloWorld',
  expirationDate: myDate
}

MDN Set() Method Documentation

I was able to fix this with the following command

typings install es6-promise es6-collections --ambient

Note that you need typings to make the above command work, if you do not have it run the following command to install it

npm install -g typings

UPDATE

typings update doesn't read --ambient it became --global also for some people you need to install the definitions of the above libraries, just use the following command

typings install dt~es6-promise dt~es6-collections --global --save

Thanks to @bgerth for pointing this out.

Correlated Subquery is a sub-query that uses values from the outer query. In this case the inner query has to be executed for every row of outer query.

See example here http://en.wikipedia.org/wiki/Correlated_subquery

Simple subquery doesn't use values from the outer query and is being calculated only once:

SELECT id, first_name 
FROM student_details 
WHERE id IN (SELECT student_id
FROM student_subjects 
WHERE subject= 'Science'); 

CoRelated Subquery Example -

Query To Find all employees whose salary is above average for their department

 SELECT employee_number, name
       FROM employees emp
       WHERE salary > (
         SELECT AVG(salary)
           FROM employees
           WHERE department = emp.department);

Thank you. This minimized a headache

my start.sh file:

#/bin/bash

nohup forever -c php artisan your:command >>storage/logs/yourcommand.log 2>&1 &

There is one important thing only. FIRST COMMAND MUST BE "nohup", second command must be "forever" and "-c" parameter is forever's param, "2>&1 &" area is for "nohup". After running this line then you can logout from your terminal, relogin and run "forever restartall" voilaa... You can restart and you can be sure that if script halts then forever will restart it.

Both answers were good so I moved them in to a directive so that it is reusable and a second scope variable doesn't have to be defined.

Here is the fiddle if you want to see it implemented

Below is the directive:

var uniqueItems = function (data, key) {
    var result = [];
    for (var i = 0; i < data.length; i++) {
        var value = data[i][key];
        if (result.indexOf(value) == -1) {
            result.push(value);
        }
    }
    return result;
};

myApp.filter('groupBy',
            function () {
                return function (collection, key) {
                    if (collection === null) return;
                    return uniqueItems(collection, key);
        };
    });

Then it can be used as follows:

<div ng-repeat="team in players|groupBy:'team'">
    <b>{{team}}</b>
    <li ng-repeat="player in players | filter: {team: team}">{{player.name}}</li>        
</div>

Let's consider this scenario. You have App.jsx as the root file for you ReactJS SPA. In it your render() looks similar to this:

<Switch>
    <Route path="/comp" component={MyComponent} />
</Switch>

then, you should be able to use this.props.history inside MyComponent without a problem. Let's say you are rendering MySecondComponent inside MyComponent, in that case you need to call it in such manner:

<MySecondComponent {...props} />

which will pass the props from MyComponent down to MySecondComponent, thus making this.props.history available in MySecondComponent

You can actually use the Markdown Preprocessor (MarkdownPP). Running with the hypothetical book example from the other answers, you would create .mdpp files representing your chapters. The .mdpp files can then use the !INCLUDE "path/to/file.mdpp" directive, which operates recursively replacing the directive with the contents of the referenced file in the final output.

chapters/preface.mdpp
chapters/introduction.mdpp
chapters/why_markdown_is_useful.mdpp
chapters/limitations_of_markdown.mdpp
chapters/conclusions.mdpp

You would then need an index.mdpp that contained the following:

!INCLUDE "chapters/preface.mdpp"
!INCLUDE "chapters/introduction.mdpp"
!INCLUDE "chapters/why_markdown_is_useful.mdpp"
!INCLUDE "chapters/limitations_of_markdown.mdpp"
!INCLUDE "chapters/conclusions.mdpp"

To render your book you simply run the preprocessor on index.mdpp:

$ markdown-pp.py index.mdpp mybook.md

Don't forget to look at the readme.mdpp in the MarkdownPP repository for an exposition of preprocessor features suited for larger documentation projects.

This approach from Microsoft works very well and provides the option to compare one list to another and switch them to get the difference in each. If you are comparing classes simply add your objects to two separate lists and then run the comparison.

I have a code that works and use the term calculated, I'm not on postgresSQL pure tho we run on PADB

here is how it's used

create table some_table as
    select  category, 
            txn_type,
            indiv_id, 
            accum_trip_flag,
            max(first_true_origin) as true_origin,
            max(first_true_dest ) as true_destination,
            max(id) as id,
            count(id) as tkts_cnt,
            (case when calculated tkts_cnt=1 then 1 else 0 end) as one_way
    from some_rando_table
    group by 1,2,3,4    ;

To make a inline-block element align center horizontally in its parent, add text-align:center to its parent.

You have to chose 'Fill' in the Dock property.

Unity is a library like many others that allows you to get an instance of a requested type without having to create it yourself. So given.

public interface ICalculator
{
    void Add(int a, int b);
}

public class Calculator : ICalculator
{
    public void Add(int a, int b)
    {
        return a + b;
    }
}

You would use a library like Unity to register Calculator to be returned when the type ICalculator is requested aka IoC (Inversion of Control) (this example is theoretical, not technically correct).

IoCLlibrary.Register<ICalculator>.Return<Calculator>();

So now when you want an instance of an ICalculator you just...

Calculator calc = IoCLibrary.Resolve<ICalculator>();

IoC libraries can usually be configured to either hold a singleton or create a new instance every time you resolve a type.

Now let's say you have a class that relies on an ICalculator to be present you could have..

public class BankingSystem
{
    public BankingSystem(ICalculator calc)
    {
        _calc = calc;
    }

    private ICalculator _calc;
}

And you can setup the library to inject a object into the constructor when it's created.

So DI or Dependency Injection means to inject any object another might require.

You need to leverage the @ViewChild decorator to reference the child component from the parent one by injection:

import { Component, ViewChild } from 'angular2/core';  

(...)

@Component({
  selector: 'my-app',
  template: `
    <h1>My First Angular 2 App</h1>
    <child></child>
    <button (click)="submit()">Submit</button>
  `,
  directives:[App]
})
export class AppComponent { 
  @ViewChild(Child) child:Child;

  (...)

  someOtherMethod() {
    this.searchBar.someMethod();
  }
}

Here is the updated plunkr: http://plnkr.co/edit/mrVK2j3hJQ04n8vlXLXt?p=preview.

You can notice that the @Query parameter decorator could also be used:

export class AppComponent { 
  constructor(@Query(Child) children:QueryList<Child>) {
    this.childcmp = children.first();
  }

  (...)
}

Here's a solution that mixes the code by Jared Rummler and AndroidMechanic.

Note: fb://facewebmodal/f?href= redirects to a weird facebook page that doesn't have the like and other important buttons, which is why I try fb://page/. It works fine with the current Facebook version (126.0.0.21.77, June 1st 2017). The catch might be useless, I left it just in case.

public static String getFacebookPageURL(Context context)
{
    final String FACEBOOK_PAGE_ID = "123456789";
    final String FACEBOOK_URL = "MyFacebookPage";

    if(appInstalledOrNot(context, "com.facebook.katana"))
    {
        try
        {
            return "fb://page/" + FACEBOOK_PAGE_ID;
            // previous version, maybe relevant for old android APIs ?
            // return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
        }
        catch(Exception e) {}
    }
    else
    {
        return FACEBOOK_URL;
    }

}

Here's the appInstalledOrNot function which I took (and modified) from Aerrow's answer to this post

private static boolean appInstalledOrNot(Context context, String uri)
{
    PackageManager pm = context.getPackageManager();
    try
    {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        return true;
    }
    catch(PackageManager.NameNotFoundException e)
    {
    }

    return false;
}

How to get the Facebook ID of a page:

1. Go to your page
2. Right-click and View Page Source
3. Find in page: fb://page/?id=
4. Here you go!

Some Theory

$ is the name of a function like any other name you give to a function. Anyone can create a function in JavaScript and name it $ as shown below:

$ = function() { 
        alert('I am in the $ function');
    }

JQuery is a very famous JavaScript library and they have decided to put their entire framework inside a function named jQuery. To make it easier for people to use the framework and reduce typing the whole word jQuery every single time they want to call the function, they have also created an alias for it. That alias is $. Therefore $ is the name of a function. Within the jQuery source code, you can see this yourself:

window.jQuery = window.$ = jQuery;

Answer To Your Question

So what is $(function() { });?

Now that you know that $ is the name of the function, if you are using the jQuery library, then you are calling the function named $ and passing the argument function() {} into it. The jQuery library will call the function at the appropriate time. When is the appropriate time? According to jQuery documentation, the appropriate time is once all the DOM elements of the page are ready to be used.

The other way to accomplish this is like this:

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

As you can see this is more verbose so people prefer $(function() { })

So the reason why some functions cannot be called, as you have noticed, is because those functions do not exist yet. In other words the DOM has not loaded yet. But if you put them inside the function you pass to $ as an argument, the DOM is loaded by then. And thus the function has been created and ready to be used.

Another way to interpret $(function() { }) is like this:

Hey $ or jQuery, can you please call this function I am passing as an argument once the DOM has loaded?

This issue is also present on iOS Chrome.

I glanced through all the solutions above, most are very hacky.

If you don't need support for older browsers, just set the iframe width to 100vw;

iframe {
  max-width: 100%; /* Limits width to 100% of container */
  width: 100vw; /* Sets width to 100% of the viewport width while respecting the max-width above */
}

Note : Check support for viewport units https://caniuse.com/#feat=viewport-units

This answer has been updated to reflect latest stable angularjs version. One important note is that $cookieStore is a thin wrapper surrounding $cookies. They are pretty much the same in that they only work with session cookies. Although, this answers the original question, there are other solutions you may wish to consider such as using localstorage, or jquery.cookie plugin (which would give you more fine-grained control and do serverside cookies. Of course doing so in angularjs means you probably would want to wrap them in a service and use $scope.apply to notify angular of changes to models (in some cases).

One other note and that is that there is a slight difference between the two when pulling data out depending on if you used $cookie to store value or $cookieStore. Of course, you'd really want to use one or the other.

In addition to adding reference to the js file you need to inject ngCookies into your app definition such as:

angular.module('myApp', ['ngCookies']);

you should then be good to go.

Here is a functional minimal example, where I show that cookieStore is a thin wrapper around cookies:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
   <link rel="stylesheet" type="text/css" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
</head>
<body ng-controller="MyController">

  <h3>Cookies</h3>
  <pre>{{usingCookies|json}}</pre>
  <h3>Cookie Store</h3>
  <pre>{{usingCookieStore|json}}</pre>

  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular-cookies.js"></script>
  <script>
    angular.module('myApp', ['ngCookies']);
    app.controller('MyController',['$scope','$cookies','$cookieStore', 
                       function($scope,$cookies,$cookieStore) {
      var someSessionObj = { 'innerObj' : 'somesessioncookievalue'};

    $cookies.dotobject = someSessionObj;
    $scope.usingCookies = { 'cookies.dotobject' : $cookies.dotobject, "cookieStore.get" : $cookieStore.get('dotobject') };

    $cookieStore.put('obj', someSessionObj);
    $scope.usingCookieStore = { "cookieStore.get" : $cookieStore.get('obj'), 'cookies.dotobject' : $cookies.obj, };
    }
  </script>

</body>
</html>

The steps are:

1. include angular.js
2. include angular-cookies.js
3. inject ngCookies into your app module (and make sure you reference that module in the ng-app attribute)
4. add a $cookies or $cookieStore parameter to the controller
5. access the cookie as a member variable using the dot (.) operator -- OR --
6. access cookieStore using put/get methods

I had the same problem. My fix was to add headers to my PHP script which are present only when in dev environment.

This allows cross-domain requests:

header("Access-Control-Allow-Origin: *");

This tells the preflight request that it is OK for the client to send any headers it wants:

header("Access-Control-Allow-Headers: *");

This way there is no need to modify the request.

If you have sensitive data in your dev database that might potentially be leaked, then you might think twice about this.

No, there isn't. The border will always be as tall as the element.

You can achieve the same effect by wrapping the contents of the cell in a <span>, and applying height/border styles to that. Or by drawing a short vertical line in an 1 pixel wide PNG which is the correct height, and applying it as a background to the cell:

background:url(line.png) bottom right no-repeat;

Find the Run button present on the top of the Eclipse, then select Run Configuration -> Arguments, in VM arguments section just mention the heap size you want to extend as below:

-Xmx1024m

The steps in order to make a full check are:

Prepare the captor :

ArgumentCaptor<SomeArgumentClass> someArgumentCaptor = ArgumentCaptor.forClass(SomeArgumentClass.class);

verify the call to dependent on component (collaborator of subject under test). times(1) is the default value, so ne need to add it.

verify(dependentOnComponent, times(1)).send(someArgumentCaptor.capture());

Get the argument passed to collaborator

SomeArgumentClass someArgument = messageCaptor.getValue();

someArgument can be used for assertions

Try this function : mltiple queries and multiple values insertion.

function employmentStatus($Status) {
$pdo = PDO2::getInstance();

$sql_parts = array(); 
for($i=0; $i<count($Status); $i++){
    $sql_parts[] = "(:userID, :val$i)";
}

$requete = $pdo->dbh->prepare("DELETE FROM employment_status WHERE userid = :userID; INSERT INTO employment_status (userid, status) VALUES ".implode(",", $sql_parts));
$requete->bindParam(":userID", $_SESSION['userID'],PDO::PARAM_INT);
for($i=0; $i<count($Status); $i++){
    $requete->bindParam(":val$i", $Status[$i],PDO::PARAM_STR);
}
if ($requete->execute()) {
    return true;
}
return $requete->errorInfo();
}

Threads share a process and a process runs on a core, but you can use python's multiprocessing module to call your functions in separate processes and use other cores, or you can use the subprocess module, which can run your code and non-python code too.

Sometimes it may be required to execute the update atomically that is using one update request to the database without reading it first.

Also get-set attribute-save may cause problems if such updates may be done concurrently or if you need to set the new value based on the old field value.

In such cases query expressions together with update may by useful:

TemperatureData.objects.filter(id=1).update(value=F('value') + 1)

A simple solution is to do this formula:

A1*7+DATE(A2,1,1)

If it returns a Wednesday, simply change the formula to:

(A1*7+DATE(A2,1,1))-2

This will only work for dates within one calendar year.

Building on Aravind's answer to fix the problem pointed out by ceklock in his comment, I added a method to verify that the dateString doesn't contain any invalid character.

Here is how I do:

private boolean isDateCorrect(String dateString) {
    try {
        Date date = mDateFormatter.parse(dateString);
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);
        return matchesOurDatePattern(dateString);    //added my method
    }
    catch (ParseException e) {
        return false;
    }
}

/**
 * This will check if the provided string matches our date format
 * @param dateString
 * @return true if the passed string matches format 2014-1-15 (YYYY-MM-dd)
 */
private boolean matchesDatePattern(String dateString) {
    return dateString.matches("^\\d+\\-\\d+\\-\\d+");
}

In case you are color picky, use this code to customize every segment.

Step 1: Windows: Open user settings (ctrl + ,) Mac: Command + Shift + P

Step 2: Search for "workbench: color customizations" and select Edit in settings.json. Page the following code inside existing {} and customize as you like.

"workbench.colorCustomizations": {
    "terminal.background":"#131212",
    "terminal.foreground":"#dddad6",
    "terminal.ansiBlack":"#1D2021",
    "terminal.ansiBrightBlack":"#665C54",
    "terminal.ansiBrightBlue":"#0D6678",

I am not very familiar with these sorts of problems so am a bit lost!

My example comment to @qubyte above got chopped, so here's something that's easier to read...

The method @surjikal described above works for branch commits, but it didn't work for a tree commit I was trying include.

The archive mode also works for commits. For example, fetch @ a2fbf83

yarn:

yarn add  https://github.com/github/fetch/archive/a2fbf834773b8dc20eef83bb53d081863d3fc87f.tar.gz

format:

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

It's better to use images for testing the speed. But if you have to deal with zip files, the below code works.

var fileURL = "your/url/here/testfile.zip";

var request = new XMLHttpRequest();
var avoidCache = "?avoidcache=" + (new Date()).getTime();;
request.open('GET', fileURL + avoidCache, true);
request.responseType = "application/zip";
var startTime = (new Date()).getTime();
var endTime = startTime;
request.onreadystatechange = function () {
    if (request.readyState == 2)
    {
        //ready state 2 is when the request is sent
        startTime = (new Date().getTime());
    }
    if (request.readyState == 4)
    {
        endTime = (new Date()).getTime();
        var downloadSize = request.responseText.length;
        var time = (endTime - startTime) / 1000;
        var sizeInBits = downloadSize * 8;
        var speed = ((sizeInBits / time) / (1024 * 1024)).toFixed(2);
        console.log(downloadSize, time, speed);
    }
}

request.send();

This will not work very well with files < 10MB. You will have to run aggregated results on multiple download attempts.

File protocol URIs are like this

file://[HOST]/[PATH]

that's why you often see file URLs like this (3 slashes) file:///c:\path...

So if the host is server01, you want

file://server01/folder/path....

This is according to the wikipedia page on file:// protocols and checks out with .NET's Uri.IsWellFormedUriString method.

Watch out if you are using Maven. Your folder's structure must be right.

When using Maven, the WEB-INF directory must be inside webapp:

src/main/webapp/WEB-INF

I use the following syntax:

objTest = {"error": true, "message": "test message"};

get error:

 var name = "error"
 console.log(objTest[name]);

get message:

 name = "message"
 console.log(objTest[name]);

The Reason for Warning is your using Old ADT (Android development tools), so Update your ADT by following the procedures below

Procedure 1:

1. Inside Eclipse Click Help menu
2. Choose Check for Updates
3. It will show Required Updates in that window choose All options using Check box or else choose ADT Updated.

Procedure 2:

Click Help > Install New Software. In the Work with field, enter: https://dl-ssl.google.com/android/eclipse/ Select Developer Tools / Android Development Tools. Click Next and complete the wizard.

This is not a correct method of updating record in SQL:

command.CommandText = "UPDATE Student(LastName, FirstName, Address, City) VALUES (@ln, @fn, @add, @cit) WHERE LastName='" + lastName + "' AND FirstName='" + firstName+"'";

You should write it like this:

command.CommandText = "UPDATE Student 
SET Address = @add, City = @cit Where FirstName = @fn and LastName = @add";

Then you add the parameters same as you added them for the insert operation.

Best way to divide a div vertically --

#parent {
    margin: 0;
    width: 100%;
}
.left {
    float: left;
    width: 60%;
}
.right {
    overflow: hidden;
    width: 40%;
}

The following command will create a copy in a new window. So you can continue see both original file and the new file.

:w {newfilename} | sp #

I voted for Josh's answer, but would like to add one more to the list:

System.InvalidOperationException should be thrown if the argument is valid, but the object is in a state where the argument shouldn't be used.

Update Taken from MSDN:

InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments.

Let's say that your object has a PerformAction(enmSomeAction action) method, valid enmSomeActions are Open and Close. If you call PerformAction(enmSomeAction.Open) twice in a row then the second call should throw the InvalidOperationException (since the arugment was valid, but not for the current state of the control)

Since you're already doing the right thing by programming defensively I have one other exception to mention is ObjectDisposedException. If your object implements IDisposable then you should always have a class variable tracking the disposed state; if your object has been disposed and a method gets called on it you should raise the ObjectDisposedException:

public void SomeMethod()
{
    If (m_Disposed) {
          throw new ObjectDisposedException("Object has been disposed")
     }
    // ... Normal execution code
}

Update: To answer your follow-up: It is a bit of an ambiguous situation, and is made a little more complicated by a generic (not in the .NET Generics sense) data type being used to represent a specific set of data; an enum or other strongly typed object would be a more ideal fit--but we don't always have that control.

I would personally lean towards the ArgumentOutOfRangeException and provide a message that indicates the valid values are 1-12. My reasoning is that when you talk about months, assuming all integer representations of months are valid, then you are expecting a value in the range of 1-12. If only certain months (like months that had 31 days) were valid then you would not be dealing with a Range per-se and I would throw a generic ArgumentException that indicated the valid values, and I would also document them in the method's comments.

Update

There has been recent improvements in datetime API with JSR-310.

Instant now = Instant.now();
Instant yesterday = now.minus(1, ChronoUnit.DAYS);
System.out.println(now);
System.out.println(yesterday);

https://ideone.com/91M1eU

Outdated answer

You are subtracting the wrong number:

Use Calendar instead:

private Date yesterday() {
    final Calendar cal = Calendar.getInstance();
    cal.add(Calendar.DATE, -1);
    return cal.getTime();
}

Then, modify your method to the following:

private String getYesterdayDateString() {
        DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
        return dateFormat.format(yesterday());
}

A trick that works is to position box #2 with position: absolute instead of position: relative. We usually put a position: relative on an outer box (here box #2) when we want an inner box (here box #3) with position: absolute to be positioned relative to the outer box. But remember: for box #3 to be positioned relative to box #2, box #2 just need to be positioned. With this change, we get:

And here is the full code with this change:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
        <style type="text/css">

            /* Positioning */
            #box1 { overflow: hidden }
            #box2 { position: absolute }
            #box3 { position: absolute; top: 10px }

            /* Styling */
            #box1 { background: #efe; padding: 5px; width: 125px }
            #box2 { background: #fee; padding: 2px; width: 100px; height: 100px }
            #box3 { background: #eef; padding: 2px; width: 75px; height: 150px }

        </style>
    </head>
    <body>
        <br/><br/><br/>
        <div id="box1">
            <div id="box2">
                <div id="box3"/>
            </div>
        </div>

The best answer is to add a Resources/.gitignore file under Resources containing:

# Ignore any file in this directory except for this file and *.foo files
*
!/.gitignore
!*.foo

If you are unwilling or unable to add that .gitignore file, there is an inelegant solution:

# Ignore any file but *.foo under Resources. Update this if we add deeper directories
Resources/*
!Resources/*/
!Resources/*.foo
Resources/*/*
!Resources/*/*/
!Resources/*/*.foo
Resources/*/*/*
!Resources/*/*/*/
!Resources/*/*/*.foo
Resources/*/*/*/*
!Resources/*/*/*/*/
!Resources/*/*/*/*.foo

You will need to edit that pattern if you add directories deeper than specified.

The main function can have two parameters, argc and argv. argc is an integer (int) parameter, and it is the number of arguments passed to the program.

The program name is always the first argument, so there will be at least one argument to a program and the minimum value of argc will be one. But if a program has itself two arguments the value of argc will be three.

Parameter argv points to a string array and is called the argument vector. It is a one dimensional string array of function arguments.

Add XAttribute in the constructor of the XElement, like

new XElement("Conn", new XAttribute("Server", comboBox1.Text));

You can also add multiple attributes or elements via the constructor

new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));

or you can use the Add-Method of the XElement to add attributes

XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);

In my case I added the following 4 lines to $middlewareGroups (in app/Http/Kernel.php):

'api' => [
    \App\Http\Middleware\EncryptCookies::class,
    \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \App\Http\Middleware\VerifyCsrfToken::class,
    'throttle:60,1',
    'bindings',
],

IMPORTANT: The 4 new lines must be added BEFORE 'throttle' and 'bindings'!

Otherwise a "CSRF token not match" error will rise. I've struggled in this for several hours just to find the order is important.

This allowed me to access session in my API. I also added VerifyCsrfToken as when cookies/sessions are involved, CSRF needs to be taken care of.

The semantics of setTimeout are roughly the same as in a web browser: the timeout arg is a minimum number of ms to wait before executing, not a guarantee. Furthermore, passing 0, a non-number, or a negative number, will cause it to wait a minimum number of ms. In Node, this is 1ms, but in browsers it can be as much as 50ms.

The reason for this is that there is no preemption of JavaScript by JavaScript. Consider this example:

setTimeout(function () {
  console.log('boo')
}, 100)
var end = Date.now() + 5000
while (Date.now() < end) ;
console.log('imma let you finish but blocking the event loop is the best bug of all TIME')

The flow here is:

1. schedule the timeout for 100ms.
2. busywait for 5000ms.
3. return to the event loop. check for pending timers and execute.

If this was not the case, then you could have one bit of JavaScript "interrupt" another. We'd have to set up mutexes and semaphors and such, to prevent code like this from being extremely hard to reason about:

var a = 100;
setTimeout(function () {
  a = 0;
}, 0);
var b = a; // 100 or 0?

The single-threadedness of Node's JavaScript execution makes it much simpler to work with than most other styles of concurrency. Of course, the trade-off is that it's possible for a badly-behaved part of the program to block the whole thing with an infinite loop.

Is this a better demon to battle than the complexity of preemption? That depends.

Instead of

 <input id="Remember" name="Remember" type="checkbox" value="@Model.Remember" />

use:

 @Html.EditorFor(x => x.Remember)

That will give you a checkbox specifically for Remember

Generally i live this situation when parent of my object is hidden. for example when the html is like this:

    <div class="div-parent" style="display:none">
        <div class="div-child" style="display:block">
        </div>
    </div>

if you ask if child is visible like:

    $(".div-child").is(":visible");

it will return false because its parent is not visible so that div wont be visible, also.

A comparison between the different Visual Studio Express editions can be found at Visual Studio Express (archive.org link). The difference between Windows and Windows Desktop is that with the Windows edition you can build Windows Store Apps (using .NET, WPF/XAML) while the Windows Desktop edition allows you to write classic Windows Desktop applications. It is possible to install both products on the same machine.

Visual Studio Express 2010 allows you to build Windows Desktop applications. Writing Windows Store applications is not possible with this product.

For learning I would suggest Notepad and the command line. While an IDE provides significant productivity enhancements to professionals, it can be intimidating to a beginner. If you want to use an IDE nevertheless I would recommend Visual Studio Express 2013 for Windows Desktop.

To use information_schema and not collide with other sessions:

select * 
from tempdb.INFORMATION_SCHEMA.COLUMNS
where table_name =
    object_name(
        object_id('tempdb..#test'),
        (select database_id from sys.databases where name = 'tempdb'))

For me the best and the simplest way of understanding the difference is:

var service, factory;
service = factory = function(injection) {}

How AngularJS instantiates particular components (simplified):

// service
var angularService = new service(injection);

// factory
var angularFactory = factory(injection);

So, for the service, what becomes the AngularJS component is the object instance of the class which is represented by service declaration function. For the factory, it is the result returned from the factory declaration function. The factory may behave the same as the service:

var factoryAsService = function(injection) {
  return new function(injection) {
    // Service content
  }
}

The simplest way of thinking is the following one:

• Service is an singleton object instance. Use services if you want to provide a singleton object for your code.
• Factory is a class. Use factories if you want to provide custom classes for your code (can't be done with services because they are already instantiated).

The factory 'class' example is provided in the comments around, as well as provider difference.

the first,Using get_encoding_type to get the files type of encode:

import os    
from chardet import detect

# get file encoding type
def get_encoding_type(file):
    with open(file, 'rb') as f:
        rawdata = f.read()
    return detect(rawdata)['encoding']

the second, opening the files with the type:

open(current_file, 'r', encoding = get_encoding_type, errors='ignore')

To answer your specific question, you cannot have two methods with the same name and the same arguments in a single class; using the HttpGet and HttpPost attributes doesn't distinguish the methods.

To address this, I'd typically include the view model for the form you're posting:

public class HomeController : Controller
{
    [HttpGet]
    public ActionResult Index()
    {
        Some Code--Some Code---Some Code
        return View();
    }

    [HttpPost]
    public ActionResult Index(formViewModel model)
    {
        do work on model --
        return View();
    }

}

Adding to Brian Agnew's answer.

You can also do //div[@id='..' or @class='...] and you can have parenthesized expressions inside //div[@id='..' and (@class='a' or @class='b')].

Swift 5, Spacing Between UITableViewCell

    1. Use sections instead of rows
    2. Each section should return one row
    3. Assign your cell data like this e.g [indexPath.section], instead of row
    4. Use UITableView Method "heightForHeader" and return your desired spacing
    5. Do rest things as you were doing it

if you have image file from your input form. you can use like this

let images = new Image();
images.onload = () => {
 console.log("Image Size", images.width, images.height)
}
images.onerror = () => result(true);

let fileReader = new FileReader();
fileReader.onload = () => images.src = fileReader.result;
fileReader.onerror = () => result(false);
if (fileTarget) {
   fileReader.readAsDataURL(fileTarget);
}

I just run this command as a root from terminal and problem is solved,

sudo apt-get install -y postgis postgresql-9.3-postgis-2.1
pip install psycopg2

or

sudo apt-get install libpq-dev python-dev
pip install psycopg2

Instead of using the outrageously convoluted data structures required by ggplot2, you can use the native R functions:

tab<-read.delim(text="

Company1 300 350
Company2 320 430
Company3 310 420
",as.is=TRUE,sep=" ",row.names=1)

tab<-t(tab)

plot(tab[,1],type="b",ylim=c(min(tab),max(tab)),col="red",lty=1,ylab="Value",lwd=2,xlab="Year",xaxt="n")
lines(tab[,2],type="b",col="black",lty=2,lwd=2)
lines(tab[,3],type="b",col="blue",lty=3,lwd=2)
grid()

axis(1,at=c(1:nrow(tab)),labels=rownames(tab))

Perhaps this should be the select (if I understand the question correctly)

select user.user_fname, user.user_lname, parent.user_fname, parent.user_lname
... As before

What about paint.getTextBounds() (object method)

With all the undeniable benefits provided by inheritance, here's some of its disadvantages.

Disadvantages of Inheritance:

1. You can't change the implementation inherited from super classes at runtime (obviously because inheritance is defined at compile time).
2. Inheritance exposes a subclass to details of its parent class implementation, that's why it's often said that inheritance breaks encapsulation (in a sense that you really need to focus on interfaces only not implementation, so reusing by sub classing is not always preferred).
3. The tight coupling provided by inheritance makes the implementation of a subclass very bound up with the implementation of a super class that any change in the parent implementation will force the sub class to change.
4. Excessive reusing by sub-classing can make the inheritance stack very deep and very confusing too.

On the other hand Object composition is defined at runtime through objects acquiring references to other objects. In such a case these objects will never be able to reach each-other's protected data (no encapsulation break) and will be forced to respect each other's interface. And in this case also, implementation dependencies will be a lot less than in case of inheritance.

$timeIn30Minutes = mktime(idate("H"), idate("i") + 30);

or

$timeIn30Minutes = time() + 30*60; // 30 minutes * 60 seconds/minute

The result will be a UNIX timestamp of the current time plus 30 minutes.

Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Add --pre to get the latest pre release:

sudo gem install cocoapods --pre

If you originally installed the cocoapods gem using sudo, you should use that command again.

Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.

You can't delete objects, they are removed when there are no more references to them. You can delete references with delete.

However, if you have created circular references in your objects you may have to de-couple some things.

This is an old question but the topic is very important and always current. In case anyone wants to go beyond simple getters/setters i have wrote an article about superpowered properties in python with support for slots, observability and reduced boilerplate code.

from objects import properties, self_properties


class Car:
    with properties(locals(), 'meta') as meta:

    def __init__(self, brand: str, max_speed: float = 200):
        self_properties(self, locals())

    def _on_off_listener(self, prop, old, on):
        if on:
            print(f"{self.brand} Turned on, Runnnnnn")
        else:
            self._speed = 0
            print(f"{self.brand} Turned off.")

    def _on_acceleration(self, prop, old, speed):
        if self.on:
            if speed > self.max_speed:
                print(f"{self.brand} {speed}km/h Bang! Engine exploded!")
                self.on = False
            else:
                print(f"{self.brand} New speed: {speed}km/h")
        else:
            print(f"{self.brand} Car is off, no speed change")

This class can be used like this:

mycar = Car('Ford')

# Car is turned off
for speed in range(0, 300, 50):
    mycar.speed = speed

# Car is turned on
mycar.on = True
for speed in range(0, 350, 50):
    mycar.speed = speed

This code will produce the following output:

Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Turned on, Runnnnnn
Ford New speed: 0km/h
Ford New speed: 50km/h
Ford New speed: 100km/h
Ford New speed: 150km/h
Ford New speed: 200km/h
Ford 250km/h Bang! Engine exploded!
Ford Turned off.
Ford Car is off, no speed change

Aside from looking into root cause issues like file leaks, etc. in order to do a legitimate increase the "open files" limit and have that persist across reboots, consider editing

/etc/security/limits.conf

by adding something like this

jetty soft nofile 2048
jetty hard nofile 4096

where "jetty" is the username in this case. For more details on limits.conf, see http://linux.die.net/man/5/limits.conf

log off and then log in again and run

ulimit -n

to verify that the change has taken place. New processes by this user should now comply with this change. This link seems to describe how to apply the limit on already running processes but I have not tried it.

The default limit 1024 can be too low for large Java applications.

Solution for Windows:

• Open the cmd or powershell as admin
• CD into the folder containing the .box file
• vagrant box add --name name_of_my_box 'name_of_my_box.box'
• vagrant box list should show the new box in the list

Solution for MAC:

• Open terminal
• CD into the folder containing the .box file
• vagrant box add --name name_of_my_box "./name_of_my_box.box"
• vagrant box list should show the new box in the list

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

jQuery doesn't work on plain object literals. You can use the below function in a similar way to search all 'id's (or any other property), regardless of its depth in the object:

function getObjects(obj, key, val) {
    var objects = [];
    for (var i in obj) {
        if (!obj.hasOwnProperty(i)) continue;
        if (typeof obj[i] == 'object') {
            objects = objects.concat(getObjects(obj[i], key, val));
        } else if (i == key && obj[key] == val) {
            objects.push(obj);
        }
    }
    return objects;
}

Use like so:

getObjects(TestObj, 'id', 'A'); // Returns an array of matching objects

Gallery is the best solution, i have tried it. I was working on one mail app, in which mails in the inbox where displayed as listview, i wanted an horizontal view, i just converted listview to gallery and everything worked fine as i needed without any errors. For the scroll effect i enabled gesture listener for the gallery. I hope this answer may help u.

For the record, I like Job's answer above but I'm curious about a solution just using the variable name by itself in a "do-nothing" statement:

void foo(int x) {
    x; /* unused */
    ...
}

Sure, this has drawbacks; for instance, without the "unused" note it looks like a mistake rather than an intentional line of code.

The benefit is that no DEFINE is needed and it gets rid of the warning.

Are there any performance, optimization, or other differences?

If your path environment variable contains Python (eg. C:\Python27\) you can run your py file simply from Windows command line (cmd). Howto here.

Here is a complete jquery plugin that solves this problem:

https://github.com/bigspotteddog/ScrollToFixed

The description of this plugin is as follows:

This plugin is used to fix elements to the top of the page, if the element would have scrolled out of view, vertically; however, it does allow the element to continue to move left or right with the horizontal scroll.

Given an option marginTop, the element will stop moving vertically upward once the vertical scroll has reached the target position; but, the element will still move horizontally as the page is scrolled left or right. Once the page has been scrolled back down past the target position, the element will be restored to its original position on the page.

This plugin has been tested in Firefox 3/4, Google Chrome 10/11, Safari 5, and Internet Explorer 8/9.

Usage for your particular case:

<script src="scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="scripts/jquery-scrolltofixed-min.js" type="text/javascript"></script>

$(document).ready(function() {
    $('#mydiv').scrollToFixed({ marginTop: 250 });
});

Maybe you can use float:right;:

.one {_x000D_
  padding-left: 1em;_x000D_
  text-color: white;_x000D_
   display:inline; _x000D_
}_x000D_
.two {_x000D_
  background-color: #00ffff;_x000D_
}_x000D_
.pull-right{_x000D_
  float:right;_x000D_
}

<html>_x000D_
<head>_x000D_
 _x000D_
  </head>_x000D_
  <body>_x000D_
      <div class="row">_x000D_
       <h3 class="one">Text</h3>_x000D_
       <button class="btn btn-secondary pull-right">Button</button>_x000D_
    </div>_x000D_
  </body>_x000D_
</html>

Change CHARSET of the complaining index field to "latin1"
i.e. ALTER TABLE tbl CHANGE myfield myfield varchar(600) CHARACTER SET latin1 DEFAULT NULL;
latin1 takes one byte for one character instead of four

The selected answer works, but it could use some improvement.

• The options should probably be initialized to default values.
• It would be nice to preserve %0 as well as the required args %1 and %2.
• It becomes a pain to have an IF block for every option, especially as the number of options grows.
• It would be nice to have a simple and concise way to quickly define all options and defaults in one place.
• It would be good to support stand-alone options that serve as flags (no value following the option).
• We don't know if an arg is enclosed in quotes. Nor do we know if an arg value was passed using escaped characters. Better to access an arg using %~1 and enclose the assignment within quotes. Then the batch can rely on the absence of enclosing quotes, but special characters are still generally safe without escaping. (This is not bullet proof, but it handles most situations)

My solution relies on the creation of an OPTIONS variable that defines all of the options and their defaults. OPTIONS is also used to test whether a supplied option is valid. A tremendous amount of code is saved by simply storing the option values in variables named the same as the option. The amount of code is constant regardless of how many options are defined; only the OPTIONS definition has to change.

EDIT - Also, the :loop code must change if the number of mandatory positional arguments changes. For example, often times all arguments are named, in which case you want to parse arguments beginning at position 1 instead of 3. So within the :loop, all 3 become 1, and 4 becomes 2.

This solution provides Unix style arguments within a Windows batch. This is not the norm for Windows - batch usually has the options preceding the required arguments and the options are prefixed with /.

The techniques used in this solution are easily adapted for a Windows style of options.

• The parsing loop always looks for an option at %1, and it continues until arg 1 does not begin with /
• Note that SET assignments must be enclosed within quotes if the name begins with /.
  SET /VAR=VALUE fails
  SET "/VAR=VALUE" works. I am already doing this in my solution anyway.
• The standard Windows style precludes the possibility of the first required argument value starting with /. This limitation can be eliminated by employing an implicitly defined // option that serves as a signal to exit the option parsing loop. Nothing would be stored for the // "option".
  
  

Update 2015-12-28: Support for ! in option values

In the code above, each argument is expanded while delayed expansion is enabled, which means that ! are most likely stripped, or else something like !var! is expanded. In addition, ^ can also be stripped if ! is present. The following small modification to the un-commented code removes the limitation such that ! and ^ are preserved in option values.

I was experiencing this error and in my case the cause was that some time ago I modified the user password, and the 503 error didn't appears till I restarted the application pool.

So I fixed it setting the new password on Applications Pools / Advanced Settings / Identity / [...] / Set... / Password / Confirm Password

Also worth checking is if there are any errors in the return type of your interface methods. I could reproduce this issue by having an unintended return type like Call<Call<ResponseBody>>

To add on to what Egon said, simply create your blob called "folder/1.txt", and it will work. No need to create a directory.

You must have 2 classes, the fas class and the fa-* class. See Basic Use in the docs:

The fa prefix has been deprecated in version 5. The new default is the fas solid style and the fab style for brands.

// Correct (version >= 5)
<i class="fas fa-search"></i>    

// Wrong (version < 5)
<i class="fa fa-search"></i>

To add to @user3303020 answer and output the search results into a file, you can run

Get-ChildItem V:\MyFolder -name -recurse *.CopyForbuild.bat > path_to_results_filename.txt

It may be easier to search for the correct file that way.

As others have noted, embedding function pointers directly inside your structure is usually reserved for special purposes, like a callback function.

What you probably want is something more like a virtual method table.

typedef struct client_ops_t client_ops_t;
typedef struct client_t client_t, *pno;

struct client_t {
    /* ... */
    client_ops_t *ops;
};

struct client_ops_t {
    pno (*AddClient)(client_t *);
    pno (*RemoveClient)(client_t *);
};

pno AddClient (client_t *client) { return client->ops->AddClient(client); }
pno RemoveClient (client_t *client) { return client->ops->RemoveClient(client); }

Now, adding more operations does not change the size of the client_t structure. Now, this kind of flexibility is only useful if you need to define many kinds of clients, or want to allow users of your client_t interface to be able to augment how the operations behave.

This kind of structure does appear in real code. The OpenSSL BIO layer looks similar to this, and also UNIX device driver interfaces have a layer like this.

If you use the matplotlib object-oriented approach, this is a simple task using ax.set_xticklabels() and ax.set_yticklabels():

import matplotlib.pyplot as plt

# Create Figure and Axes instances
fig,ax = plt.subplots(1)

# Make your plot, set your axes labels
ax.plot(sim_1['t'],sim_1['V'],'k')
ax.set_ylabel('V')
ax.set_xlabel('t')

# Turn off tick labels
ax.set_yticklabels([])
ax.set_xticklabels([])

plt.show()

I think the key is to copy the module to the standard paths.

Once that is done, modprobe only accepts the module name, so leave off the path and ".ko" extension.

It was not the clock for me, and all the hours spent re-downloading and reinstalling were a waste of time (except for the last one, of course....).

Also, for some odd reason, just adding Read permissions to the HKCR node using psexec -i -s regedit did not work by itself.

To fix my problem on Windows 7, I made sure (using psexec -i -s regedit) that my login account had full control permission over every node in the registry and that the everyone group had read permission over every node in the registry, and did all of the steps in the following link (rebooting after each step):

This is probably overkill, but after spending 10+ hours trying to get this working, I am just happy it works... Good luck!

    if (titleDivider != null) {
        titleDivider.setBackgroundColor(res.getColor(R.color.list_menu_divider));
    }
}
}

Just add this style:

cursor: pointer;

The reason it's not happening by default is because most browsers reserve the pointer for links only (and maybe a couple other things I'm forgetting, but typically not <button>s).

More on the cursor property: https://developer.mozilla.org/en/CSS/cursor

I usually apply this to <button> and <label> by default.

NOTE: I just caught this:

the button tags have an id of #more

It's very important that each element has it's own unique id, you cannot have duplicates. Use the class attribute instead, and change your selector from #more to .more. This is actually quite a common mistake that is the cause of many problems and questions asked here. The earlier you learn how to use id, the better.

You can directly apply slice() to the variable. StackBlitz Demo

<li *ngFor="let item of list.slice(0, 10);">
   {{item.text}}
</li>

One more entry here for those that didn't make it work with any of these solutions, and need to get a return value from their function:

function foo()
{
    local v="Dimi";
    local s="";
    .....
    s+="Some message here $v $1\n"
    .....
    echo $s
}

r=$(foo "my message");
echo -e $r;

Only this trick worked in a linux I was working on with this bash:

GNU bash, version 2.2.25(1)-release (x86_64-redhat-linux-gnu)

Hope it helps someone with similar problem.

Use a semicolon

OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";

Considering that you have

$replaced = array('1' => 'value1', '4' => 'value4');
$replacement = array('4' => 'value2', '6' => 'value3');

Doing $merge = $replacement + $replaced; will output:

Array('4' => 'value2', '6' => 'value3', '1' => 'value1');

The first array from sum will have values in the final output.

Doing $merge = $replaced + $replacement; will output:

Array('1' => 'value1', '4' => 'value4', '6' => 'value3');

You can use code below to remove style default inforwindow. After you can use HTML code for inforwindow:

var inforwindow = "<div style="border-radius: 50%"><img src='URL'></div>"; // show inforwindow image circle
marker.addListener('click', function() {
    $('.gm-style-iw').next().css({'height': '0px'}); //remove arrow bottom inforwindow
    $('.gm-style-iw').prev().html(''); //remove style default inforwindows
});

There might be a semicolon or bracket missing a line before your pasted line.

It seems fine to me; every string is allowed as an array index.

As long as your array $phpinfo['PHP Core']['memory_limit'] contains the value of memory_limit, it does work the following:

• The last character of that value can signal the shorthand notation. If it's an invalid one, it's ignored.
• The beginning of the string is converted to a number in PHP's own specific way: Whitespace ignored etc.
• The text between the number and the shorthand notation (if any) is ignored.

Example:

# Memory Limit equal or higher than 64M?
$ok = (int) (bool) setting_to_bytes($phpinfo['PHP Core']['memory_limit']) >= 0x4000000;

/**
 * @param string $setting
 *
 * @return NULL|number
 */
function setting_to_bytes($setting)
{
    static $short = array('k' => 0x400,
                          'm' => 0x100000,
                          'g' => 0x40000000);

    $setting = (string)$setting;
    if (!($len = strlen($setting))) return NULL;
    $last    = strtolower($setting[$len - 1]);
    $numeric = (int) $setting;
    $numeric *= isset($short[$last]) ? $short[$last] : 1;
    return $numeric;
}

Details of the shorthand notation are outline in a PHP manual's FAQ entry and extreme details are part of Protocol of some PHP Memory Stretching Fun.

Take care if the setting is -1 PHP won't limit here, but the system does. So you need to decide how the installer treats that value.

TL;DR

JSONP is an old trick invented to bypass the security restriction that forbids us to get JSON data that is in a different website (a different origin¹) than the one we are navigating in.

The trick works by using a <script> tag that asks for the JSON from that place, e.g.: { "user":"Smith" }, but wrapped in a function, the actual JSONP ("JSON with Padding"):

peopleDataJSONP({"user":"Smith"})

Receiving it in this form enables us to use the data within our peopleDataJSONP function. JSONP is a bad practice and not needed anymore, don't use it (read below).

The problem

Say we want to use on ourweb.com some JSON data (or any raw data really) hosted at anotherweb.com. If we were to use GET request (think XMLHttpRequest, or fetch call, $.ajax, etc.), our browser would tell us it's not allowed with this ugly error:

How to get the data we want? Well, <script> tags are not subjected to this whole server (origin¹) restriction! That's why we can load a library like jQuery or Google Maps from any server, such as a CDN, without any errors.

Here's the important point: if you think about it, those libraries are actual, runnable JS code (usually a massive function with all the logic inside). But raw data? JSON data is not code. There's nothing to run; it's just plain text.

Therefore, there's no way to handle or manipulate our precious data. The browser will download the data pointed at by our <script> tag and when processing it'll rightfully complain:

wtf is this {"user":"Smith"} crap we loaded? It's not code. I can't compute, syntax error!

The JSONP hack

The old/hacky way to utilize that data? If we could make plain text somehow runnable, we could grab it on runtime. So we need anotherweb.com to send it with some logic, so when it's loaded, your code in the browser will be able to use said data. We need two things: 1) to get the data in a way that it can be run, and 2) write some code in the client so that when the data runs, this code is called and we get to use the data.

For 1) we ask the foreign server to send us the JSON data inside a JS function. The data itself is set up as that function's input. It looks like this:

peopleDataJSONP({"user":"Smith"})

which makes it JS code our browser will parse and run without complaining! Exactly like it does with the jQuery library. To receive the data like that, the client "asks" the JSONP-friendly server for it, usually done like this:

<script src="https://anotherweb.com/api/data-from-people.json?myCallback=peopleDataJSONP"></script>

As per 2), since our browser will receive the JSONP with that function name, we need a function with the same name in our code, like this:

function peopleDataJSONP(data){
  alert(data.user); // "Smith"
}

The browser will download the JSONP and run it, which calls our function, where the argument data will be the JSON data from anotherweb.com. We can now do with our data whatever we want to.

Don't use JSONP, use CORS

JSONP is a cross-site hack with a few downsides:

• We can only perform GET requests
• Since it's a GET request triggered by a simple script tag, we don't get helpful errors or progress info
• There are also some security concerns, like running in your client JS code that could be changed to a malicious payload
• It only solves the problem with JSON data, but Same-Origin security policy applies to other data (WebFonts, images/video drawn with drawImage()...)
• It's not very elegant nor readable.

The takeaway is that there's no need to use it nowadays.

You should read about CORS here, but the gist of it is:

Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell browsers to give a web application running at one origin, access to selected resources from a different origin. A web application executes a cross-origin HTTP request when it requests a resource that has a different origin (domain, protocol, or port) from its own.

1. origin is defined by 3 things: protocol, port, and host. So, for example, https://web.com is a different origin than http://web.com (different protocol) and https://web.com:8081 (different port) and obviously https://thatotherweb.net (different host)

In version 5.6.5, it is possible to set a default value on a datetime column, and even make a column that will update when the row is updated. The type definition:

CREATE TABLE foo (
    `creation_time`     DATETIME DEFAULT CURRENT_TIMESTAMP,
    `modification_time` DATETIME ON UPDATE CURRENT_TIMESTAMP
)

Reference: http://optimize-this.blogspot.com/2012/04/datetime-default-now-finally-available.html

OR makes sense (from readability point of view), when there are less values to be compared. IN is useful esp. when you have a dynamic source, with which you want values to be compared.

Another alternative is to use a JOIN with a temporary table.
I don't think performance should be a problem, provided you have necessary indexes.

+1 to @MartinNuc, you can run the mysql client in batch mode and then you won't see the long stream of "OK" lines.

The amount of time it takes to import a given SQL file depends on a lot of things. Not only the size of the file, but the type of statements in it, how powerful your server server is, and how many other things are running at the same time.

@MartinNuc says he can load 4GB of SQL in 4-5 minutes, but I have run 0.5 GB SQL files and had it take 45 minutes on a smaller server.

We can't really guess how long it will take to run your SQL script on your server.

Re your comment,

@MartinNuc is correct you can choose to make the mysql client print every statement. Or you could open a second session and run mysql> SHOW PROCESSLIST to see what's running. But you probably are more interested in a "percentage done" figure or an estimate for how long it will take to complete the remaining statements.

Sorry, there is no such feature. The mysql client doesn't know how long it will take to run later statements, or even how many there are. So it can't give a meaningful estimate for how much time it will take to complete.

You should be able to use the current directory

"%CD%"\bin\Iris.exe

What to change? Aside from the 3 or 4 dimensional array problem, you should get rid of the magic numbers (10 and 9).

const int DIM_SIZE = 10;
int myArray[DIM_SIZE][DIM_SIZE][DIM_SIZE];

for (int i = 0; i < DIM_SIZE; ++i){
    for (int t = 0; t < DIM_SIZE; ++t){            
        for (int x = 0; x < DIM_SIZE; ++x){
