Programs & Examples On #Databound

Using ddl.Items.Clear() will clear the dropdownlist however you must be sure that your dropdownlist is not set to:

AppendDataBoundItems="True"

This option will cause the rebound data to be appended to the existing list which will NOT be cleared prior to binding.

SOLUTION

Add AppendDataBoundItems="False" to your dropdownlist.

Now when data is rebound it will automatically clear all existing data beforehand.

Protected Sub ddl1_SelectedIndexChanged(sender As Object, e As EventArgs)
    ddl2.DataSource = sql2
    ddl2.DataBind()
End Sub

NOTE: This may not be suitable in all situations as appenddatbound items can cause your dropdown to append its own data on each change of the list.

TOP TIP

Still want a default list item adding to your dropdown but need to rebind data?

Use AppendDataBoundItems="False" to prevent duplication data on postback and then directly after binding your dropdownlist insert a new default list item.

ddl.Items.Insert(0, New ListItem("Select ...", ""))

I finally managed to get it working. Here the code :

private void dgvStatus_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (e.ColumnIndex != color.Index)
        return;

    e.CellStyle.BackColor = Color.FromArgb(int.Parse(((DataRowView)dgvStatus.Rows[e.RowIndex].DataBoundItem).Row[4].ToString()));
}

if anyone know a better to do this please don't hesitate to post it. I'm open to suggestion

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'
            }
        }

protected void gvBill_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)

            Total += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "InvMstAmount"));
        else if (e.Row.RowType == DataControlRowType.Footer)

            e.Row.Cells[7].Text = String.Format("{0:0}", "<b>" + Total + "</b>");
    }

I would also suggest deselecting an item after it has been clicked and use the MouseDoubleClick event

private void listBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    try {
        //Do your stuff here
        listBox.SelectedItem = null;
        listBox.SelectedIndex = -1;
    } catch (Exception ex) {
        System.Diagnostics.Debug.WriteLine(ex.Message);
    }
}

You would have got this Exception while doing a GET on http://localhost:8080/projectname/login

As Vinay has correctly stated you can definitely use

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(Model model) { 
    model.addAttribute("login", new Login()); 
    return "login"; 
}

But I am going to provide some alternative syntax which I think you were trying with Spring 3.0.

You can also achieve the above functionality with

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(Login loginModel) { 
    return "login"; 
}

and it login.jsp (assuming you are using InternalResourceViewResolver) you can have

<form:form method="POST" action="login.htm" modelAttribute="login">

Notice : modelAttribute is login and not loginModel. It is as per the class name you provide in argument. But if you want to use loginModel as modelAttribute is jsp you can do the following

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(@ModelAttribute("loginModel")Login loginModel) { 
    return "login"; 
}

and jsp would have

<form:form method="POST" action="login.htm" modelAttribute="loginModel">

I know there are just different ways for doing the same thing. But the most important point to note here -

Imp Note: When you add your model class in your methods argument (like public String displayLogin(Login loginModel)) it is automatically created and added to your Model object (which is why you can directly access it in JSP without manually putting it in model). Then it will search your request if request has attributes that it can map with the new ModelObject create. If yes Spring will inject values from request parameters to your custom model object class (Login in this case).

You can test this by doing

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(Login loginModel, Model model) { 
    System.out.println(model.asMap().get("login").equals(loginModel));
    return "login"; 
}

Note : Above creating of new custom model object may not hold true if you have given @SessionAttributes({"login"}). In this case it will get from session and populate values.

hey recently i figured it out how to set width if your gridview databound with sql dataset.first set these control RowStyle-Wrap="false" HeaderStyle-Wrap="false" and then you can set the column width as much as you like. ex : ItemStyle-Width="150px" HeaderStyle-Width="150px"

Try with below code.

Like GridView in LinkButton, Label, HtmlAnchor and HtmlInputControl.

<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
    OnRowDataBound="mainGrid_RowDataBound"  EmptyDataText="No Data Found.">
    <Columns>
        <asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
                <asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
                <a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
                <input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Handling RowDataBound event,

protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblName = (Label)e.Row.FindControl("lblName");
        LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
        HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
        HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
    }
}

Remove the visible="false" attribute and add a CSS class that is not visible by default. Then you should be able to reference the dropdown by the correct id, for example:

$("#ctl00_cphTest_test1").show();

Above ID you should serach for in the source of the rendered page in your browser.

This is working code

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            { 
                    DropDownList1.DataTextField = "user_name";
                    DropDownList1.DataValueField = "user_id";
                    DropDownList1.DataSource = getData();// get the data into the list you can set it
                    DropDownList1.DataBind();

    DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("your default selected text"));
            }
        }

Here is the code from MSDN and the link - Article Link, which you should check out for more detail.

<ComboBox Text="Is not open">
    <ComboBoxItem Name="cbi1">Item1</ComboBoxItem>
    <ComboBoxItem Name="cbi2">Item2</ComboBoxItem>
    <ComboBoxItem Name="cbi3">Item3</ComboBoxItem>
</ComboBox>

Make the div

runat="server" 

and do

if (lstFilePrefix1.SelectedValue=="Prefix2")
{
    int TotalRows = this.BindList(1);
    this.Prepare_Pager(TotalRows);
    data.Style["display"] = "block";
}

Your method isn't working because the javascript is being rendered in the top of the body tag, before the div is rendered. You'd have to include code to tell the javascript to wait for the DOM to be completely ready to take on your request, which would probably be easiest to do with jQuery.

I have come across this error when the app resides on a network share, and the device (laptop, tablet, ...) becomes disconnected from the network while the app is in use. In my case, it was due to a Surface tablet going out of wireless range. No problems after installing a better WAP.

Better solution

You can check item type in ItemCreated event:

protected void rptSummary_ItemCreated(Object sender, RepeaterItemEventArgs e) {
    if (e.Item.ItemType == ListItemType.Footer) {
        e.Item.FindControl(ctrl);
    }
    if (e.Item.ItemType == ListItemType.Header) {
        e.Item.FindControl(ctrl);
    }
}

dropdownlist.Items.Insert(0, new Listitem("--Select One--", "0");

I pasted your code into test project, added about 20 items and I get usable scroll bars, no problem, and they work as expected. When I only add a couple items (such that scrolling is unnecessary) I get no usable scrollbar. Could this be the case? that you are not adding enough items?

If you remove the ScrollViewer.VerticalScrollBarVisibility="Visible" then the scroll bars only appear when you have need of them.

Regarding the index selection style of the columns i suggest you do the following. i ran into this problem but i was going to set values dynamically using an API so what i did was this : keep in mind .CastTo<T> is simply ((T)e.Row.DataItem)

and you have to call DataBind() in order to see the changes in the grid. this way you wont run into issues if you decide to add a column to the grid.

 protected void gvdata_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if(e.Row.RowType == DataControlRowType.DataRow)
            {
                var number = e.Row.DataItem.CastTo<DataRowView>().Row["number"];
                e.Row.DataItem.CastTo<DataRowView>().Row["ActivationDate"] = DateTime.Parse(userData.basic_info.creation_date).ToShortDateString();
                e.Row.DataItem.CastTo<DataRowView>().Row["ExpirationDate"] = DateTime.Parse(userData.basic_info.nearest_exp_date).ToShortDateString();
                e.Row.DataItem.CastTo<DataRowView>().Row["Remainder"] = Convert.ToDecimal(userData.basic_info.credit).ToStringWithSeparator();

                e.Row.DataBind();
            }
        }

My solution is to run twine upload over the python -m argument.

So just use python -m:

python -m twine upload dist/*

One thing you need to realize is in Ruby everything is an object. Given that, if you don't define your methods within Module or Class, Ruby will put it within the Object class. So, your code will be local to the Object scope.

A typical approach on Object Oriented Programming is encapsulate all logic within a class:

class Point
  attr_accessor :x, :y

  # If we don't specify coordinates, we start at 0.
  def initialize(x = 0, y = 0)
    # Notice that `@` indicates instance variables.
    @x = x
    @y = y
  end

  # Here we override the `+' operator.
  def +(point)
    Point.new(self.x + point.x, self.y + point.y)
  end

  # Here we draw the point.
  def draw(offset = nil)
    if offset.nil?
      new_point = self
    else
      new_point = self + offset 
    end
    new_point.draw_absolute
  end

  def draw_absolute
    puts "x: #{self.x}, y: #{self.y}"
  end
end

first_point = Point.new(100, 200)
second_point = Point.new(3, 4)

second_point.draw(first_point)

Hope this clarifies a bit.

It's worth noting that in Firefox 3 and Safari, resizing an image by just changing the height and width doesn't look too bad. In other browsers it can look very noisy because it's using nearest-neighbor resampling. Of course, you're paying to serve a larger image, but that might not matter.

Use the -1 option (note this is a "one" digit, not a lowercase letter "L"), like this:

ls -1a

First, though, make sure your ls supports -1. GNU coreutils (installed on standard Linux systems) and Solaris do; but if in doubt, use man ls or ls --help or check the documentation. E.g.:

$ man ls
...
       -1     list one file per line.  Avoid '\n' with -q or -b

For sake of completeness, as of PHP 5.1 this works, too:

<?php
function title($title, $name) {
    return sprintf("%s. %s\r\n", $title, $name);
}
$function = new ReflectionFunction('title');
$myArray = array('Dr', 'Phil');
echo $function->invokeArgs($myArray);  // prints "Dr. Phil"
?>

See: http://php.net/reflectionfunction.invokeargs

For methods you use ReflectionMethod::invokeArgs instead and pass the object as first parameter.

If you are using ActionBarSherlock, you can get the height with

@dimen/abs__action_bar_default_height

Try this:

On first row set value 1 (e.g cell A1)

on next row set: =A1+1

Finally autocomplete the remaining rows

int row_count = dt.Rows.Count;

I am new to ruby and had to just deal with understanding the following weirdness. Might help out someone else in the future. In the end it is as was mentioned above, where 2 functions (def myvar, def myvar=) both get implicitly for accessing @myvar, but these methods can be overridden by local declarations.

class Foo
  attr_accessor 'myvar'
  def initialize
    @myvar = "A"
    myvar = "B"
    puts @myvar # A
    puts myvar # B - myvar declared above overrides myvar method
  end

  def test
    puts @myvar # A
    puts myvar # A - coming from myvar accessor

    myvar = "C" # local myvar overrides accessor
    puts @myvar # A
    puts myvar # C

    send "myvar=", "E" # not running "myvar =", but instead calls setter for @myvar
    puts @myvar # E
    puts myvar # C
  end
end

That would just be:

 Console.WriteLine(Variables.name);

and it needs to be public also:

public class Variables
{
   public static string name = "";
}

The only selector I see is a[id$="name"] (all links with id finishing by "name") but it's not as restrictive as it should.

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

dir.Delete(true); // true => recursive delete

Adding my answer, because it elaborates the idea that you can SELECT multiple columns from the table from which you subquery.

Here I needed the the most recently cast cote and it's associated information.

I first tried simply to SELECT the max(votedate) along with vote, itemid, userid etc., but while the query would return the max votedate, it would also return the a random row for the other information. Hard to see among a bunch of 1s and 0s.

This worked well:

$query = "  
    SELECT t1.itemid, t1.itemtext, t2.vote, t2.votedate, t2.userid 
    FROM
        (
        SELECT itemid, itemtext FROM oc_item ) t1
    LEFT JOIN 
        (
        SELECT vote, votedate, itemid,userid FROM oc_votes
        WHERE votedate IN 
        (select max(votedate) FROM oc_votes group by itemid)
        AND userid=:userid) t2
    ON (t1.itemid = t2.itemid)
    order by itemid ASC
";

The subquery in the WHERE clause WHERE votedate IN (select max(votedate) FROM oc_votes group by itemid) returns one record - the record with the max vote date.

The previous answers explain type parameters (T, E, etc.), but don't explain the wildcard, "?", or the differences between them, so I'll address that.

First, just to be clear: the wildcard and type parameters are not the same. Where type parameters define a sort of variable (e.g., T) that represents the type for a scope, the wildcard does not: the wildcard just defines a set of allowable types that you can use for a generic type. Without any bounding (extends or super), the wildcard means "use any type here".

The wildcard always come between angle brackets, and it only has meaning in the context of a generic type:

public void foo(List<?> listOfAnyType) {...}  // pass a List of any type

never

public <?> ? bar(? someType) {...}  // error. Must use type params here

or

public class MyGeneric ? {      // error
    public ? getFoo() { ... }   // error
    ...
}

It gets more confusing where they overlap. For example:

List<T> fooList;  // A list which will be of type T, when T is chosen.
                  // Requires T was defined above in this scope
List<?> barList;  // A list of some type, decided elsewhere. You can do
                  // this anywhere, no T required.

There's a lot of overlap in what's possible with method definitions. The following are, functionally, identical:

public <T> void foo(List<T> listOfT) {...}
public void bar(List<?> listOfSomething)  {...}

So, if there's overlap, why use one or the other? Sometimes, it's honestly just style: some people say that if you don't need a type param, you should use a wildcard just to make the code simpler/more readable. One main difference I explained above: type params define a type variable (e.g., T) which you can use elsewhere in the scope; the wildcard doesn't. Otherwise, there are two big differences between type params and the wildcard:

Type params can have multiple bounding classes; the wildcard cannot:

public class Foo <T extends Comparable<T> & Cloneable> {...}

The wildcard can have lower bounds; type params cannot:

public void bar(List<? super Integer> list) {...}

In the above the List<? super Integer> defines Integer as a lower bound on the wildcard, meaning that the List type must be Integer or a super-type of Integer. Generic type bounding is beyond what I want to cover in detail. In short, it allows you to define which types a generic type can be. This makes it possible to treat generics polymorphically. E.g. with:

public void foo(List<? extends Number> numbers) {...}

You can pass a List<Integer>, List<Float>, List<Byte>, etc. for numbers. Without type bounding, this won't work -- that's just how generics are.

Finally, here's a method definition which uses the wildcard to do something that I don't think you can do any other way:

public static <T extends Number> void adder(T elem, List<? super Number> numberSuper) {
    numberSuper.add(elem);
}

numberSuper can be a List of Number or any supertype of Number (e.g., List<Object>), and elem must be Number or any subtype. With all the bounding, the compiler can be certain that the .add() is typesafe.

Class methods are usually used to create instances of that class

For example, [NSString stringWithFormat:@"SomeParameter"]; returns an NSString instance with the parameter that is sent to it. Hence, because it is a Class method that returns an object of its type, it is also called a convenience method.

Change the Encoding of the stream writer. It's a property.

http://msdn.microsoft.com/en-us/library/system.io.streamwriter.encoding.aspx

So:

sw.Encoding = Encoding.GetEncoding(28591);

Prior to writing to the stream.

I'm using this:

$ echo -e '\u2620'
?

This is pretty easier than searching a hex representation... I'm using this in my shell scripts. That works on gnome-term and urxvt AFAIK.

Something like this might be the easiest way.

I found this;

Excel VBA ComboBox Lists

vba- Can a combobox present more then one column on it's textbox part?

and this may help;

Populating ComboBoxes VBA

I added a sort of demo here;

This is a guess. Generally recursion probably doesn't beat looping often or ever on problems of decent size if both are using really good algorithms(not counting implementation difficulty) , it may be different if used with a language w/ tail call recursion(and a tail recursive algorithm and with loops also as part of the language)-which would probably have very similar and possibly even prefer recursion some of the time.

Explanation by analogy

Imagine that you wrote a letter to your pen pal but that you wrote it in different languages each time.

For example, you might have chosen to write your first letter in Tamil, and the second in German etc.

In order for your friend to translate those letters, your friend would need to:

• (i) identify the language type, and
• (ii) and then translate it accordingly. But identifying a language is not that easy - it's going to take a lot of computational energy. It would be much easier if you wrote the language you are sending across on the top of your letter - that would make life a lot easier for your friend.

So then, in order to highlight the language you are writing in, you simple annotate the language (e.g. "French") on the top of your letter.

How would your friend know or be able to read or distinguish between the different language types you are specifying at the top of your letter? That's easy: you agree upon this beforehand.

Tying the analogy back in with HTML

Because there are different types of data formats which need to be sent over the internet, specifying the data type up front would allow the corresponding client to properly interpret and render the data accordingly to the user.

Why do we have different data formats?

Principally because they serve different purposes and have different abilities.

For example, a PDF format is very different from a picture format - which is also different from a sound format - both serve very different purposes and accordingly are written different prior to being sent over the internet.

This version takes advantage that object keys are unique. We process the original array and collect the colors by group in a new object. Then create new objects from that group -> color array map.

var myArray = [{
      group: "one",
      color: "red"
    }, {
      group: "two",
      color: "blue"
    }, {
      group: "one",
      color: "green"
    }, {
      group: "one",
      color: "black"
    }];

    //new object with keys as group and
    //color array as value
    var newArray = {};

    //iterate through each element of array
    myArray.forEach(function(val) {
      var curr = newArray[val.group]

      //if array key doesnt exist, init with empty array
      if (!curr) {
        newArray[val.group] = [];
      }

      //append color to this key
      newArray[val.group].push(val.color);
    });

    //remove elements from previous array
    myArray.length = 0;

    //replace elements with new objects made of
    //key value pairs from our created object
    for (var key in newArray) {
      myArray.push({
        'group': key,
        'color': newArray[key]
      });
    }

Please note that this does not take into account duplicate colors of the same group, so it is possible to have multiple of the same color in the array for a single group.

You can find the codes in the DB2 Information Center. Here's a definition of the -302 from the z/OS Information Center:

THE VALUE OF INPUT VARIABLE OR PARAMETER NUMBER position-number IS INVALID OR TOO LARGE FOR THE TARGET COLUMN OR THE TARGET VALUE

On Linux/Unix/Windows DB2, you'll look under SQL Messages to find your error message. If the code is positive, you'll look for SQLxxxxW, if it's negative, you'll look for SQLxxxxN, where xxxx is the code you're looking up.

    public static function normalizeUrl(string $url) {
        $parts = parse_url($url);
        return $parts['scheme'] .
            '://' .
            $parts['host'] .
            implode('/', array_map('rawurlencode', explode('/', $parts['path'])));

    }

You could try using float:left; or display:inline-block;.

Both of these will change the element's behaviour from defaulting to 100% width to defaulting to the natural width of its contents.

However, note that they'll also both have an impact on the layout of the surrounding elements as well. I would suggest that inline-block will have less of an impact though, so probably best to try that first.

You can also try my ServiceStack JsonSerializer it's the fastest .NET JSON serializer at the moment. It supports serializing DataContracts, any POCO Type, Interfaces, Late-bound objects including anonymous types, etc.

Basic Example

var customer = new Customer { Name="Joe Bloggs", Age=31 };
var json = JsonSerializer.SerializeToString(customer);
var fromJson = JsonSerializer.DeserializeFromString<Customer>(json); 

Note: Only use Microsofts JavaScriptSerializer if performance is not important to you as I've had to leave it out of my benchmarks since its up to 40x-100x slower than the other JSON serializers.

function parseBool(value) {
    if (typeof value === "boolean") return value;

    if (typeof value === "number") {
        return value === 1 ? true : value === 0 ? false : undefined;
    }

    if (typeof value != "string") return undefined;

    return value.toLowerCase() === 'true' ? true : false;
}

OneToOneField: if second table is related with

table2_col1 = models.OneToOneField(table1,on_delete=models.CASCADE, related_name='table1_id')

table2 will contains only one record corresponding to table1's pk value, i.e table2_col1 will have unique value equal to pk of table

table2_col1 == models.ForeignKey(table1, on_delete=models.CASCADE, related_name='table1_id')

table2 may contains more than one record corresponding to table1's pk value.

Based on Piotr Migdals response I want to give an alternate solution enabling the possibility for a vector of strings:

myVectorOfStrings <- c("foo", "bar")
matchExpression <- paste(myVectorOfStrings, collapse = "|")
# [1] "foo|bar"
df %>% select(matches(matchExpression))

Making use of the regex OR operator (|)

ATTENTION: If you really have a plain vector of column names (and do not need the power of RegExpression), please see the comment below this answer (since it's the cleaner solution).

You can achieve this using the apache commons java library. Take a look at these two functions within it:
- getLevenshteinDistance
- getFuzzyDistance

I tried this it works

open

vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php

and change this

 $conf[CURLOPT_SSL_VERIFYHOST] = 2;
 `enter code here`$conf[CURLOPT_SSL_VERIFYPEER] = true;

to this

$conf[CURLOPT_SSL_VERIFYHOST] = 0;
$conf[CURLOPT_SSL_VERIFYPEER] = FALSE;

Unless you really want to keep the dictionary, I think the best solution is to use the csv Python module to read the file. Then, you get rows of data and you can change member_phone or whatever you want ; finally, you can use the csv module again to save the file in the same format as you opened it.

Code for reading:

import csv

with open("my_input_file.txt", "r") as f:
   reader = csv.reader(f, delimiter=":")
   lines = list(reader)

Code for writing:

with open("my_output_file.txt", "w") as f:
   writer = csv.writer(f, delimiter=":")
   writer.writerows(lines)

Of course, you need to adapt your change() function:

def change(lines):
    a = input('ID')
    for line in lines:
      if line[0] == a:
        d=str(input("phone"))
        line[3]=d
        break
    else:
      print "not"

$.fn.extend({
    insertAtCaret: function(myValue) {
        var elemSelected = window.getSelection();
        if(elemSelected) {
            var startPos = elemSelected.getRangeAt(0).startOffset;
            var endPos = elemSelected.getRangeAt(0).endOffset;
            this.val(this.val().substring(0, startPos)+myValue+this.val().substring(endPos,this.val().length));
        } else {
            this.val(this.val()+ myValue) ;
        }
    }
});

An inner class has access to all members of the outer class, but it does not have an implicit reference to a parent class instance (unlike some weirdness with Java). So if you pass a reference to the outer class to the inner class, it can reference anything in the outer class instance.

You can simply write

try
 {
    //Your Logic and code
 }
 catch (Exception ex)
 {
    //Error message in  alert box
    Response.Write("<script>alert('Error :" +ex.Message+"');</script>");
 }

it will work fine

As you would like to get argument (United) for which value is given (5) you might also consider using bidirectional map (e.g. provided by Guava: http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/BiMap.html).

$('.toggle img').each(function(index) { 
    if($(this).attr('data-id') == '4')
    {
        $(this).attr('data-block', 'something');
        $(this).attr('src', 'something.jpg');
    }
});

or

$('.toggle img[data-id="4"]').attr('data-block', 'something');
$('.toggle img[data-id="4"]').attr('src', 'something.jpg');

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

this code probable help you .

<iframe src="" onload="this.width=screen.width;this.height=screen.height;">

Another modification:

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

The difference with this is that it waits 10 seconds AFTER the ajax call is one. So really the time between refreshes is 10 seconds + length of ajax call. The benefit of this is if your server takes longer than 10 seconds to respond, you don't get two (and eventually, many) simultaneous AJAX calls happening.

Also, if the server fails to respond, it won't keep trying.

I've used a similar method in the past using .ajax to handle even more complex behaviour:

function update() {
  $("#notice_div").html('Loading..'); 
  $.ajax({
    type: 'GET',
    url: 'response.php',
    timeout: 2000,
    success: function(data) {
      $("#some_div").html(data);
      $("#notice_div").html(''); 
      window.setTimeout(update, 10000);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      $("#notice_div").html('Timeout contacting server..');
      window.setTimeout(update, 60000);
    }
}

This shows a loading message while loading (put an animated gif in there for typical "web 2.0" style). If the server times out (in this case takes longer than 2s) or any other kind of error happens, it shows an error, and it waits for 60 seconds before contacting the server again.

This can be especially beneficial when doing fast updates with a larger number of users, where you don't want everyone to suddenly cripple a lagging server with requests that are all just timing out anyways.

byte[] asciiBytes = Encoding.ASCII.GetBytes("Y");

Check your my.cnf file in your MySQL program directory, look for

[mysqld]
datadir=

The datadir is the location where your MySQL database is stored.

You can use:

  const sha1 = require('sha1');
  const crypt = sha1('Text');
  console.log(crypt);

For install:

  sudo npm install -g sha1
  npm install sha1 --save

Use django.utils.timezone.make_aware function to make your naive datetime objects timezone aware and avoid those warnings.

It converts naive datetime object (without timezone info) to the one that has timezone info (using timezone specified in your django settings if you don't specify it explicitly as a second argument):

import datetime
from django.conf import settings
from django.utils.timezone import make_aware

naive_datetime = datetime.datetime.now()
naive_datetime.tzinfo  # None

settings.TIME_ZONE  # 'UTC'
aware_datetime = make_aware(naive_datetime)
aware_datetime.tzinfo  # <UTC>

Since you may have more than one legends in a plot, a way to selectively remove just one of the titles without leaving an empty space is to set the name argument of the scale_ function to NULL, i.e.

scale_fill_discrete(name = NULL)

(kudos to @pascal for a comment on another thread)

Use screen. It is very simple to use and works like vnc for terminals. http://www.bangmoney.org/presentations/screen.html

How about

[@"7" intValue];

Additionally if you want an NSNumber you could do

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter numberFromString:@"7"];

Use time module to convert data.

Code snippet:

import time 
tring='20150103040500'
var = int(time.mktime(time.strptime(tring, '%Y%m%d%H%M%S')))
print var

I solved it as follows:

1) try to locate ctr1.o and ctri.o files by using find -name ctr1.o

I got the following in my computer: $/usr/lib/i386-linux/gnu

2) Add that path to PATH (also LIBRARY_PATH) environment variable (in order to see which is the name: type env command in the Terminal):

$PATH=/usr/lib/i386-linux/gnu:$PATH
$export PATH

Pass Today as value as mentioned below in $viewQuery property :

$web = Get-SPWeb "http://sitename"
$list = $web.Lists.TryGetList($listtitle)
write-host "Exporting '$($list.Title)' data from '$($web.Title)' site.."
$viewTitle = "Program Events" #Title property
#Add the column names from the ViewField property to a string collection
$viewFields = New-Object System.Collections.Specialized.StringCollection
$viewFields.Add("Event Date") > $null
$viewFields.Add("Title") > $null
#Query property
$viewQuery = "<Where><Geq><FieldRef Name='EventDate' /><Value IncludeTimeValue='TRUE' Type='DateTime'><Today/></Value></Geq></Where><OrderBy><FieldRef Name='EventDate' Ascending='True' /></OrderBy>"
#RowLimit property
$viewRowLimit = 30
#Paged property
$viewPaged = $true
#DefaultView property
$viewDefaultView = $false
#Create the view in the destination list
$newview = $list.Views.Add($viewTitle, $viewFields, $viewQuery, $viewRowLimit, $viewPaged, $viewDefaultView)
Write-Host ("View '" + $newview.Title + "' created in list '" + $list.Title + "' on site " + $web.Url)
$web.Dispose()

if you dont wanna use DISTINCT use GROUP BY

 SELECT * FROM myTABLE GROUP BY EmailAddress

This isn't a direct answer to this question, but I wanted to leave a note here for anyone who may be having the same issue as me when trying to configure an upstream branch.

Be wary of push.default.

With older git versions, the default was matching, which would cause very undesirable behaviour if you have, for example:

Local branch "master" tracking to origin/master

Remote branch "upstream" tracking to upstream/master

If you tried to "git push" when on the "upstream" branch, with push.default matching git would automatically try to merge the local branch "master" into "upstream/master", causing a whole lot of chaos.

This gives more sane behaviour:

git config --global push.default upstream

Add this:

align-items: flex-start;

to the rule for .content {}. That fixes it in your pen for me, at least (in both Firefox & Chrome).

By default, .content has align-items: stretch, which makes it size all of its auto-height children to match its own height, per http://dev.w3.org/csswg/css-flexbox/#algo-stretch. In contrast, the value flex-start lets the children compute their own heights, and align themselves at its starting edge (and overflow, and trigger a scrollbar).

where row.name.StartsWith(q, true, System.Globalization.CultureInfo.CurrentCulture)

You can try this. but before you need to install psutil using sudo pip install psutil

import psutil
for proc in psutil.process_iter(attrs=['pid', 'name']):
    if 'ichat' in proc.info['name']:
        proc.kill()

Why not set ON CASCADE DELETE on Foreign Key patron_info.pid?

if your text doesn't spill over two rows then you can do line-height: ; in your CSS, the more line-height you give, the lower on the container it will hold.

This might help you.

ParentID = pDoc.offsetParent;
alert(ParentID.id); 

mysql> GRANT ALL ON *.* to root@'192.168.1.%' IDENTIFIED BY 'your-root-password';  

The wildcard character is a "%" instead of an "*"

Use:

System.Text.Encoding.ASCII.GetString(buf);

You can try this:

HTML

    <tr>
        <td class="shrink">element1</td>
        <td class="shrink">data</td>
        <td class="shrink">junk here</td>
        <td class="expand">last column</td>
    </tr>

        <td class="shrink">of </td>
        <td class="shrink">these</td>
        <td class="expand">rows</td>
    </tr>
</table>

CSS

table {
    border: 1px solid green;
    border-collapse: collapse;
    width:100%;
}

table td {
    border: 1px solid green;
}

table td.shrink {
    white-space:nowrap
}
table td.expand {
    width: 99%
}

You can change the class of the entire table and use the cascade in the CSS: http://jsbin.com/oyunuy/1/

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.

Edit: Seven years later, this answer still gets occasional upvotes. It's fine if you are looking for runtime checking, but I would now recommend compile-time type checking using Typescript, or possibly Flow. See https://stackoverflow.com/a/31420719/610585 above for more.

Original answer:

It's not built into the language, but you can do it yourself quite easily. Vibhu's answer is what I would consider the typical way of type checking in Javascript. If you want something more generalized, try something like this: (just an example to get you started)

typedFunction = function(paramsList, f){
    //optionally, ensure that typedFunction is being called properly  -- here's a start:
    if (!(paramsList instanceof Array)) throw Error('invalid argument: paramsList must be an array');

    //the type-checked function
    return function(){
        for(var i=0,p,arg;p=paramsList[i],arg=arguments[i],i<paramsList.length; i++){
            if (typeof p === 'string'){
                if (typeof arg !== p) throw new Error('expected type ' + p + ', got ' + typeof arg);
            }
            else { //function
                if (!(arg instanceof p)) throw new Error('expected type ' + String(p).replace(/\s*\{.*/, '') + ', got ' + typeof arg);
            }
        }
        //type checking passed; call the function itself
        return f.apply(this, arguments);
    }
}

//usage:
var ds = typedFunction([Date, 'string'], function(d, s){
    console.log(d.toDateString(), s.substr(0));
});

ds('notadate', 'test');
//Error: expected type function Date(), got string
ds();
//Error: expected type function Date(), got undefined
ds(new Date(), 42);
//Error: expected type string, got number
ds(new Date(), 'success');
//Fri Jun 14 2013 success

If your existing code is already relying on from datetime import datetime, you can also simply also import date

from datetime import datetime, timedelta, date
print isinstance(datetime.today().date(), date)

You use it like this:

SELECT  age, name
FROM    users
UNION
SELECT  25 AS age, 'Betty' AS name

Use UNION ALL to allow duplicates: if there is a 25-years old Betty among your users, the second query will not select her again with mere UNION.

I was able to use

return View::make('myviewfolder.myview', compact('view1','view2','view3'));

I don't know if it's because I am using PHP 5.5 it works great :)

To send a Whatsapp message from a website, use the below URL.

URL: https://api.whatsapp.com/send?phone=XXXXX&text=dummy

Here the phone and text are parameters were one of them is required.

• phone: To whom we need to send the message
• text: The text needs to share.

This URL is also can be used. It displays a blank screen if there is no application found!

URL: whatsapp://send?text=The text to share!

Note: All the above will work in web, only if WhatsApp desktop app is installed

Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885

This doesn't rely on serialization nor on content negotiation.

[HttpGet]
public ContentResult Index() {
    return new ContentResult {
        ContentType = "text/html",
        StatusCode = (int)HttpStatusCode.OK,
        Content = "<html><body>Hello World</body></html>"
    };
}

INNER JOIN gets all records that are common between both tables based on the supplied ON clause.

LEFT JOIN gets all records from the LEFT linked and the related record from the right table ,but if you have selected some columns from the RIGHT table, if there is no related records, these columns will contain NULL.

RIGHT JOIN is like the above but gets all records in the RIGHT table.

FULL JOIN gets all records from both tables and puts NULL in the columns where related records do not exist in the opposite table.

You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'

The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.

Solution is to Add common-logging.x.x jar file

Shallow copy with copy.copy()

# It copies.
c = C()
d = copy.copy(c)
d.x = [3]
assert c.x == [1]
assert d.x == [3]

# It's shallow.
c = C()
d = copy.copy(c)
d.x[0] = 3
assert c.x == [3]

Set style= "display:none;". By setting visible=false, it will not render button in the browser. Thus,client side script wont execute.

<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />

html markup should be

<button id="btnsave" onclick="fncsave()">Save</button>

Change javascript to

<script type="text/javascript">
     function fncsave()
     {
        document.getElementById('<%= savebtn.ClientID %>').click();
     }
</script>

will print all but very first column:

awk '{$1=""; print $0}' somefile

will print all but two first columns:

awk '{$1=$2=""; print $0}' somefile

var unique = array
    .map(p => p.age)
    .filter((age, index, arr) => arr.indexOf(age) == index)
    .sort(); // sorting is optional

// or in ES6

var unique = [...new Set(array.map(p => p.age))];

// or with lodash

var unique = _.uniq(_.map(array, 'age'));

ES6 example

const data = [
  { name: "Joe", age: 17}, 
  { name: "Bob", age: 17}, 
  { name: "Carl", age: 35}
];

const arr = data.map(p => p.age); // [17, 17, 35]
const s = new Set(arr); // {17, 35} a set removes duplications, but it's still a set
const unique = [...s]; // [17, 35] Use the spread operator to transform a set into an Array
// or use Array.from to transform a set into an array
const unique2 = Array.from(s); // [17, 35]

If you want selection to only flash, not remain in the selected state, you can call, in

didSelectRowAtIndexPath

the following

[tableView deselectRowAtIndexPath:indexPath animated:YES];

so it will flash the selected state and revert.

The first answer is essentially correct, but if you want the very simplest way to accomplish the desired result, here's a stand-alone code example demonstrating how to do it with a semaphore (which is also how dispatch groups work behind the scenes, JFYI):

#include <dispatch/dispatch.h>
#include <stdio.h>

main()
{
        dispatch_queue_t myQ = dispatch_queue_create("my.conQ", DISPATCH_QUEUE_CONCURRENT);
        dispatch_semaphore_t mySem = dispatch_semaphore_create(0);

        dispatch_async(myQ, ^{ printf("Hi I'm block one!\n"); sleep(2); dispatch_semaphore_signal(mySem);});
        dispatch_async(myQ, ^{ printf("Hi I'm block two!\n"); sleep(4); dispatch_semaphore_signal(mySem);});
        dispatch_async(myQ, ^{ dispatch_semaphore_wait(mySem, DISPATCH_TIME_FOREVER); printf("Hi, I'm the final block!\n"); });
        dispatch_main();
}

When you are developing an SDK. You need some extra operation.

1) create Localizable.strings as usual in YourLocalizeDemoSDK.

2) create the same Localizable.strings in YourLocalizeDemo.

3) find your Bundle Path of YourLocalizeDemoSDK.

Swift4:

// if you use NSLocalizeString in NSObject, you can use it like this
let value = NSLocalizedString("key", tableName: nil, bundle: Bundle(for: type(of: self)), value: "", comment: "")

Bundle(for: type(of: self)) helps you to find the bundle in YourLocalizeDemoSDK. If you use Bundle.main instead, you will get a wrong value(in fact it will be the same string with the key).

But if you want to use the String extension mentioned by dr OX. You need to do some more. The origin extension looks like this.

extension String {
    var localized: String {
        return NSLocalizedString(self, tableName: nil, bundle: Bundle.main, value: "", comment: "")
    }
}

As we know, we are developing an SDK, Bundle.main will get the bundle of YourLocalizeDemo's bundle. That's not what we want. We need the bundle in YourLocalizeDemoSDK. This is a trick to find it quickly.

Run the code below in a NSObject instance in YourLocalizeDemoSDK. And you will get the URL of YourLocalizeDemoSDK.

let bundleURLOfSDK = Bundle(for: type(of: self)).bundleURL
let mainBundleURL = Bundle.main.bundleURL

Print both of the two url, you will find that we can build bundleURLofSDK base on mainBundleURL. In this case, it will be:

let bundle = Bundle(url: Bundle.main.bundleURL.appendingPathComponent("Frameworks").appendingPathComponent("YourLocalizeDemoSDK.framework")) ?? Bundle.main

And the String extension will be:

extension String {
    var localized: String {
        let bundle = Bundle(url: Bundle.main.bundleURL.appendingPathComponent("Frameworks").appendingPathComponent("YourLocalizeDemoSDK.framework")) ?? Bundle.main
        return NSLocalizedString(self, tableName: nil, bundle: bundle, value: "", comment: "")
    }
}

Hope it helps.

Try making the bottom margin 100%.

margin-bottom: 100%;

the window.onload event will fire when everything is loaded, including images etc.

You would want to check the DOM ready status if you wanted your js code to execute as early as possible, but you still need to access DOM elements.

InetAddress.getLocalHost().getHostName() is better (as explained by Nick), but still not very good

One host can be known under many different hostnames. Usually you'll be looking for the hostname your host has in a specific context.

For example, in a web application, you might be looking for the hostname used by whoever issued the request you're currently handling. How to best find that one depends on which framework you're using for your web application.

In some kind of other internet-facing service, you'll want the hostname your service is available through from the 'outside'. Due to proxies, firewalls etc this might not even be a hostname on the machine your service is installed on - you might try to come up with a reasonable default, but you should definitely make this configurable for whoever installs this.

Use the DateTime.Now property. This returns a DateTime object that contains a Year and Month property (both are integers).

string currentMonth = DateTime.Now.Month.ToString();
string currentYear = DateTime.Now.Year.ToString();

monthLabel.Text = currentMonth;
yearLabel.Text = currentYear;

Here's a little cmd script you can copy-n-paste into a file named something like where.cmd:

@echo off
rem - search for the given file in the directories specified by the path, and display the first match
rem
rem    The main ideas for this script were taken from Raymond Chen's blog:
rem
rem         http://blogs.msdn.com/b/oldnewthing/archive/2005/01/20/357225.asp
rem
rem
rem - it'll be nice to at some point extend this so it won't stop on the first match. That'll
rem     help diagnose situations with a conflict of some sort.
rem

setlocal

rem - search the current directory as well as those in the path
set PATHLIST=.;%PATH%
set EXTLIST=%PATHEXT%

if not "%EXTLIST%" == "" goto :extlist_ok
set EXTLIST=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
:extlist_ok

rem - first look for the file as given (not adding extensions)
for %%i in (%1) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i

rem - now look for the file adding extensions from the EXTLIST
for %%e in (%EXTLIST%) do @for %%i in (%1%%e) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i

If the command sha256sum is not available (on Mac OS X v10.9 (Mavericks) for example), you can use:

Having observed people, who have learned Java first, struggle with the concepts of pointers and memory management in C++, I'd say that learning C first is a good idea, in order to grasp these two concepts, isolated from the complexities of other C++ features.

I have the same issue where I want a single script to work with a table that has columns added periodically by other developers. Not only that, but I am supporting many different versions of our database as customers may not all be up-to-date with the current version.

I took the solution by Jonas and modified it slightly. This allows me to make a copy of the row and then change the primary key before adding it back into the original source table. This is also really handy for working with tables that do not allow NULL values in columns and you don't want to have to specify each column name in the INSERT.

This code copies the row for 'ABC' to 'XYZ'

SELECT * INTO #TempRow FROM SourceTable WHERE KeyColumn = 'ABC';
UPDATE #TempRow SET KeyColumn = 'XYZ';
INSERT INTO SourceTable SELECT * FROM #TempRow;
DELETE #TempRow;

Once you have finished the drop the temp table.

DROP TABLE #TempRow;

Swift 4 Examples

Example #1 using closure

NotificationCenter.default.addObserver(forName: .UIApplicationUserDidTakeScreenshot, 
                                       object: nil, 
                                       queue: OperationQueue.main) { notification in
    print("\(notification) that a screenshot was taken!")
}

Example #2 with selector

NotificationCenter.default.addObserver(self, 
                                       selector: #selector(screenshotTaken), 
                                       name: .UIApplicationUserDidTakeScreenshot, 
                                       object: nil)

@objc func screenshotTaken() {
    print("Screenshot taken!")
}

It can do so if you have implicitly or explicitly set the alignment of the struct. A struct that is aligned 4 will always be a multiple of 4 bytes even if the size of its members would be something that's not a multiple of 4 bytes.

Also a library may be compiled under x86 with 32-bit ints and you may be comparing its components on a 64-bit process would would give you a different result if you were doing this by hand.

MS-SQL has a setting to prevent recursive trigger firing. This is confirgured via the sp_configure stored proceedure, where you can turn recursive or nested triggers on or off.

In this case, it would be possible, if you turn off recursive triggers to link the record from the inserted table via the primary key, and make changes to the record.

In the specific case in the question, it is not really a problem, because the result is to delete the record, which won't refire this particular trigger, but in general that could be a valid approach. We implemented optimistic concurrency this way.

The code for your trigger that could be used in this way would be:

ALTER TRIGGER myTrigger
    ON someTable
    AFTER INSERT
AS BEGIN
DELETE FROM someTable
    INNER JOIN inserted on inserted.primarykey = someTable.primarykey
    WHERE ISNUMERIC(inserted.someField) = 1
END

In my case, I was actually missing a tab in between ifeq and the command on the next line. No spaces were there to begin with.

ifeq ($(wildcard $DIR_FILE), )
cd $FOLDER; cp -f $DIR_FILE.tpl $DIR_FILE.xs;
endif

Should have been:

ifeq ($(wildcard $DIR_FILE), )
<tab>cd $FOLDER; cp -f $DIR_FILE.tpl $DIR_FILE.xs;
endif

Note the <tab> is an actual tab character

The slowdown is not necessarily the same with any compiler.

I haven't used Delphi or Kylix but back in the MS-DOS days, a Turbo Pascal program would compile almost instantaneously, while the equivalent Turbo C++ program would just crawl.

The two main differences were a very strong module system and a syntax that allowed single-pass compilation.

It's certainly possible that compilation speed just hasn't been a priority for C++ compiler developers, but there are also some inherent complications in the C/C++ syntax that make it more difficult to process. (I'm not an expert on C, but Walter Bright is, and after building various commercial C/C++ compilers, he created the D language. One of his changes was to enforce a context-free grammar to make the language easier to parse.)

Also, you'll notice that generally Makefiles are set up so that every file is compiled separately in C, so if 10 source files all use the same include file, that include file is processed 10 times.

I had this problem along with mismatch in ITERATOR_DEBUG_LEVEL. As a sunday-evening problem after all seemed ok and good to go, I was put out for some time. Working in de VS2017 IDE (Solution Explorer) I had recently added/copied a sourcefile reference to my project (ctrl-drag) from another project. Looking into properties->C/C++/Preprocessor - at source file level, not project level - I noticed that in a Release configuration _DEBUG was specified instead of NDEBUG for this source file. Which was all the change needed to get rid of the problem.

Use 10.0.2.2 for default AVD and 10.0.3.2 for Genymotion

Just discovered a handy way to get an index while parsing. My mind was blown.

$handle = fopen("test.csv", "r");
for ($i = 0; $row = fgetcsv($handle ); ++$i) {
    // Do something will $row array
}
fclose($handle);

Source: link

I just encountered this problem. I tried a few things, but settled on using JSoup. The jar is about 132k, which is a bit big, but if you download the source and take out some of the methods you will not be using, then it is not as big.
=> Good thing about it is that it will handle badly formed HTML

Here's a good example from their site.

File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");

//http://jsoup.org/cookbook/input/load-document-from-url
//Document doc = Jsoup.connect("http://example.com/").get();

Element content = doc.getElementById("content");
Elements links = content.getElementsByTag("a");
for (Element link : links) {
  String linkHref = link.attr("href");
  String linkText = link.text();
}

You can do this pretty easily using Docker, so no extra libs required. Just run this command:

docker run --rm -it -v "$GOPATH":/go -w /go/src/github.com/iron-io/ironcli golang:1.4.2-cross sh -c '
for GOOS in darwin linux windows; do
  for GOARCH in 386 amd64; do
    echo "Building $GOOS-$GOARCH"
    export GOOS=$GOOS
    export GOARCH=$GOARCH
    go build -o bin/ironcli-$GOOS-$GOARCH
  done
done
'

SELECT ... INTO ... only works if the table specified in the INTO clause does not exist - otherwise, you have to use:

INSERT INTO dbo.TABLETWO
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

This assumes there's only two columns in dbo.TABLETWO - you need to specify the columns otherwise:

INSERT INTO dbo.TABLETWO
  (col1, col2)
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

In process all threads share system resource like heap Memory etc. while Thread has its own stack

So your ans should be heap memory which all threads share for a process.

As already answered, this is per spec not possible with the fetch-API, yet. But I have to note:

If you are on node, there's the querystring package. It can stringify/parse objects/querystrings:

var querystring = require('querystring')
var data = { key: 'value' }
querystring.stringify(data) // => 'key=value'

...then just append it to the url to request.

However, the problem with the above is, that you always have to prepend a question mark (?). So, another way is to use the parse method from nodes url package and do it as follows:

var url = require('url')
var data = { key: 'value' }
url.format({ query: data }) // => '?key=value'

See query at https://nodejs.org/api/url.html#url_url_format_urlobj

This is possible, as it does internally just this:

search = obj.search || (
    obj.query && ('?' + (
        typeof(obj.query) === 'object' ?
        querystring.stringify(obj.query) :
        String(obj.query)
    ))
) || ''

It won't be fast, and there will be a lot for you to type (unless you generate the SQL from user_tab_columns), but here is what I use when I need to compare two tables row-by-row and column-by-column.

The query will return all rows that

• Exists in table1 but not in table2
• Exists in table2 but not in table1
• Exists in both tables, but have at least one column with a different value

(common identical rows will be excluded).

"PK" is the column(s) that make up your primary key. "a" will contain A if the present row exists in table1. "b" will contain B if the present row exists in table2.

select pk
      ,decode(a.rowid, null, null, 'A') as a
      ,decode(b.rowid, null, null, 'B') as b
      ,a.col1, b.col1
      ,a.col2, b.col2
      ,a.col3, b.col3
      ,...
  from table1 a 
  full outer 
  join table2 b using(pk)
 where decode(a.col1, b.col1, 1, 0) = 0
    or decode(a.col2, b.col2, 1, 0) = 0
    or decode(a.col3, b.col3, 1, 0) = 0
    or ...;

Edit Added example code to show the difference described in comment. Whenever one of the values contains NULL, the result will be different.

with a as(
   select 0    as col1 from dual union all
   select 1    as col1 from dual union all
   select null as col1 from dual
)
,b as(
   select 1    as col1 from dual union all
   select 2    as col1 from dual union all
   select null as col1 from dual
)   
select a.col1
      ,b.col1
      ,decode(a.col1, b.col1, 'Same', 'Different') as approach_1
      ,case when a.col1 <> b.col1 then 'Different' else 'Same' end as approach_2       
  from a,b
 order 
    by a.col1
      ,b.col1;    




col1   col1_1   approach_1  approach_2
====   ======   ==========  ==========
  0        1    Different   Different  
  0        2    Different   Different  
  0      null   Different   Same         <--- 
  1        1    Same        Same       
  1        2    Different   Different  
  1      null   Different   Same         <---
null       1    Different   Same         <---
null       2    Different   Same         <---
null     null   Same        Same       

In order to avoid this kind of ClassCastException, if you have:

class A
class B extends A

You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:

public B(A a) {
    super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
    // If B class has more attributes, then you would initilize them here
}

you should add charset=UTF-8 in meta tag and use json_encode for special characters

json_encode function converts special characters in UTF8 standard

If you set up the code as a plain Java module in Gradle, then it's really easy to have Gradle give you a jar file with the contents. That jar file will have only your code, not the other Apache libraries it depends on. I'd recommend distributing it this way; it's a little weird to bundle dependencies inside your library, and it's more normal for users of those libraries to have to include those dependencies on their own (because otherwise there are collisions of those projects are already linking copies of the library, perhaps of different versions). What's more, you avoid potential licensing problems around redistributing other people's code if you were to publish your library.

Take the code that also needs to be compiled to a jar, and move it to a separate plain Java module in Android Studio:

1. File menu > New Module... > Java Library
2. Set up the library, Java package name, and class names in the wizard. (If you don't want it to create a class for you, you can just delete it once the module is created)
3. In your Android code, set up a dependency on the new module so it can use the code in your new library:
4. File > Project Structure > Modules > (your Android Module) > Dependencies > + > Module dependency. See the screenshot below:
5. Choose your module from the list in the dialog that comes up:

Hopefully your project should be building normally now. After you do a build, a jar file for your Java library will be placed in the build/libs directory in your module's directory. If you want to build the jar file by hand, you can run its jar build file task from the Gradle window:

It is always C:\Windows\System32\WindowsPowershell\v1.0. It was left like that for backward compability is what I heard or read somewhere.

You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client.

You could try to run the 2to3 tool on your code, and try to have it translated automatically. References to httplib will automatically be rewritten to use http.client instead.

Like CodeHater said you are accessing the variable before it is set.

To fix this move the ng-init directive to the first div.

<body ng-app>
    <div ng-controller="testController" ng-init="testInput='value'">
        <input type="hidden" id="testInput" ng-model="testInput" />
       {{ testInput }}
    </div>
</body>

That should work!

I use this expression. It takes into account a space after a comma, which I have come across.

(?:,"|^"|, ")(""|[\w\W]*?)(?=",|"$)|(?:,(?!")|^(?!"))([^,]*?)(?=$|,)|(\r\n|\n)

Just to offer the alternative to the Test-Path cmdlet (since nobody mentioned it):

[System.IO.File]::Exists($path)

Does (almost) the same thing as

Test-Path $path -PathType Leaf

except no support for wildcard characters

To achieve what you are looking for you can use the viewport-percentage length vw.

Here is a quick example I made on jsfiddle.

HTML:

<div class="square">
    <h1>This is a Square</h1>
</div>

CSS:

.square {
    background: #000;
    width: 50vw;
    height: 50vw;
}
.square h1 {
    color: #fff;
}

I am sure there are many other ways to do this but this way seemed the best to me.

These symptoms occur if you are using the Genymotion emulator (on Windows or Linux) at the same time as Android Studio:

adb server is out of date.  killing...
ADB server didn't ACK
* failed to start daemon *

Genymotion includes its own copy of adb, which interferes with the one bundled in the Android SDK.

The easiest way to fix seems to be to update your Genymotion Settings so it uses the same ADB as your Android SDK:

Just check the "Use custom Android SDK tools" option and enter your desired location.

Finally solved issue of reinitialization of select2 after ajax call.

You can call this in success function of ajax.

Note : Don't forget to replace ".selector" to your class of <select class="selector"> element.

jQuery('.select2-container').remove();

jQuery('.selector').select2({
   placeholder: "Placeholder text",
   allowClear: true
});

jQuery('.select2-container').css('width','100%');

This works for me :

$scope.array1 = $scope.array1.concat(array2)

In your case it would be :

$scope.actions.data = $scope.actions.data.concat(data)

Consider an array of pointers. A pointer is really an address; so when you initialize the array, you are analogously telling the computer, "allocate this block of memory to hold these X numbers (which are addresses of other items)." Then if you change one of the pointers, you are just changing what it points to; it is still a numerical address which is itself sitting in the same spot.

A reference is analogous to an alias. If you were to declare an array of references, you would basically be telling the computer, "allocate this amorphous blob of memory consisting of all these different items scattered around."

Just as normal, using data-original-title:

Html:

<div rel='tooltip' data-original-title='<h1>big tooltip</h1>'>Visible text</div>

Javascript:

$("[rel=tooltip]").tooltip({html:true});

The html parameter specifies how the tooltip text should be turned into DOM elements. By default Html code is escaped in tooltips to prevent XSS attacks. Say you display a username on your site and you show a small bio in a tooltip. If the html code isn't escaped and the user can edit the bio themselves they could inject malicious code.

The best to reuse existing code, take Maven's ComparableVersion class

advantages:

• Apache License, Version 2.0,
• tested,
• used (copied) in multiple projects like spring-security-core, jboss etc
• multiple features
• it's already a java.lang.Comparable
• just copy-paste that one class, no third-party dependencies

Don't include dependency to maven-artifact as that will pull various transitive dependencies

As a minor addition to this thread, in general you want to avoid using the views that begin with sys.sys* as Microsoft is only including them for backwards compatibility. For your code, you should probably use sys.server_principals. This is assuming you are using SQL 2005 or greater.

Plan: Write out the shuffle without relying on a library to do the heavy lifting. Example: Go through the list from the beginning starting with element 0; find a new random position for it, say 6, put 0’s value in 6 and 6’s value in 0. Move on to element 1 and repeat this process, and so on through the rest of the list

import random
iteration = random.randint(2, 100)
temp_var = 0
while iteration > 0:

    for i in range(1, len(my_list)): # have to use range with len()
        for j in range(1, len(my_list) - i):
            # Using temp_var as my place holder so I don't lose values
            temp_var = my_list[i]
            my_list[i] = my_list[j]
            my_list[j] = temp_var

        iteration -= 1

You can use the following code to generate a requirements.txt file:

pip install pipreqs

pipreqs /path/to/project

more info related to pipreqs can be found here.

Sometimes you come across pip freeze, but this saves all packages in the environment including those that you don't use in your current project.

If all steps (in existing answers) dont work , Just close eclipse and again open eclipse .

I do something very similar to you.

I'll usually include a DEBUG param that defaults to false and I can set to true at run time. Then wrap the debug statements into an "If DEBUG" block.

I also use a logging table with many of my jobs so that I can review processes and timing. My Debug code gets output there as well. I include the calling param name, a brief description, row counts affected (if appropriate), a comments field and a time stamp.

Good debugging tools is one of the sad failings of all SQL platforms.

You could change your code in this way:

public delegate void CallbackHandler(string str);

public class ServerRequest
{
    public void DoRequest(string request, CallbackHandler callback)
    {
        // do stuff....
        callback("asdf");
    }
}

Move the Directory clause out of the virtualhost, and put it before declaring the virtualhost.

Drove me nuts for a long time too. Don't know why. It's a Debian thing.

If 'they' are using a self-signed certificate it is up to them to take the steps required to make their server usable. Specifically that means providing their certificate to you offline in a trustworthy way. So get them to do that. You then import that into your truststore using the keytool as described in the JSSE Reference Guide. Don't even think about the insecure TrustManager posted here.

EDIT For the benefit of the seventeen (!) downvoters, and numerous commenters below, who clearly have not actually read what I have written here, this is not a jeremiad against self-signed certificates. There is nothing wrong with self-signed certificates when implemented correctly. But, the correct way to implement them is to have the certificate delivered securely via an offline process, rather than via the unauthenticated channel they are going to be used to authenticate. Surely this is obvious? It is certainly obvious to every security-aware organization I have ever worked for, from banks with thousands of branches to my own companies. The client-side code-base 'solution' of trusting all certificates, including self-signed certificates signed by absolutely anybody, or any arbitary body setting itself up as a CA, is ipso facto not secure. It is just playing at security. It is pointless. You are having a private, tamperproof, reply-proof, injection-proof conversation with ... somebody. Anybody. A man in the middle. An impersonator. Anybody. You may as well just use plaintext.

I was appalled at the clumsiness of the CLASSPATH, JAVA_HOME, and PATH ideas, in Windows, to keep track of Java files. I got here, because of multiple JREs, and how to content with it. Without regurgitating information, from a guy much more clever than me, I would rather point to to his article on this issue, which for me, resolves it perfectly.

Article by: Ted Neward: Multiple Java Homes: Giving Java Apps Their Own JRE

With the exponential growth of Java as a server-side development language has come an equivablent exponential growth in Java development tools, environments, frameworks, and extensions. Unfortunately, not all of these tools play nicely together under the same Java VM installation. Some require a Servlet 2.1-compliant environment, some require 2.2. Some only run under JDK 1.2 or above, some under JDK 1.1 (and no higher). Some require the "com.sun.swing" packages from pre-Swing 1.0 days, others require the "javax.swing" package names.

Worse yet, this problem can be found even within the corporate enterprise, as systems developed using Java from just six months ago may suddenly "not work" due to the installation of some Java Extension required by a new (seemingly unrelated) application release. This can complicate deployment of Java applications across the corporation, and lead customers to wonder precisely why, five years after the start of the infamous "Installing-this-app-breaks-my-system" woes began with Microsoft's DLL schemes, we still haven't progressed much beyond that. (In fact, the new .NET initiative actually seeks to solve the infamous "DLL-Hell" problem just described.)

This paper describes how to configure a Java installation such that a given application receives its own, private, JRE, allowing multiple Java environments to coexist without driving customers (or system administrators) insane...

Above method (1) works great if you have clicked on a link and opened link in a New Tab in current browser window.

2)

<a href="javascript:history.back()">Go Back</a>

Above method (2) only works ok if you have clicked on a link and opened link in a Current Tab in current browser window.

It will not work if you have open link in New Tab. Here history.back() will not work if link is opened in New Tab of web browser.

In my case, I needed an input button to have a line break before it.
I applied the following style to the button and it worked:

clear:both;

If you have already staged files, simply unstage them:

git reset HEAD [file-name-A.ext] [file-name-B.ext]

Then add them bit by bit back in.

For installing multiple packages on the command line, just pass them as a space-delimited list, e.g.:

pip install wsgiref boto

For installing from a text file, then, from pip install --help:

-r FILENAME, --requirement=FILENAME

Install all the packages listed in the given requirements file. This option can be used multiple times.

Take a look at the pip documentation regarding requirements files for their general layout and syntax - note that you can generate one based on current environment / site-packages with pip freeze if you want a quick example - e.g. (based on having installed wsgiref and boto in a clean virtualenv):

$ pip freeze
boto==2.3.0
wsgiref==0.1.2

JS

        function showAlert(){
         $('#alert').show();
         setTimeout(function() { 
             $('#alert').hide(); 
         }, 5000);
        }

HTML

<div class="alert alert-success" id="alert" role="alert" style="display:none;" >YOUR MESSAGE</div>

If you need to work a lot with database in your code and you know the structure of your table, I suggest you do it as follow:

First of all you can define a class which will help you to make objects capable of keeping your table rows data. For example in my project I created a class named Document.java to keep data of a single document from my database and I made an array list of these objects to keep data of my table which is gain by a query.

package financialdocuments;

import java.lang.*;
import java.util.HashMap;

/**
 *
 * @author Administrator
 */
public class Document {

 private int document_number; 
 private boolean document_type;
 private boolean document_status; 
 private StringBuilder document_date;
 private StringBuilder document_statement;
 private int document_code_number;
 private int document_employee_number;
 private int document_client_number;
 private String document_employee_name;
 private String document_client_name;
 private long document_amount;
 private long document_payment_amount;

 HashMap<Integer,Activity> document_activity_hashmap;


public Document(int dn,boolean dt,boolean ds,String dd,String dst,int dcon,int den,int dcln,long da,String dena,String dcna){

    document_date = new StringBuilder(dd);
    document_date.setLength(10);
    document_date.setCharAt(4, '.');
    document_date.setCharAt(7, '.');
    document_statement = new StringBuilder(dst);
    document_statement.setLength(50);
    document_number = dn; 
    document_type = dt;
    document_status = ds;
    document_code_number = dcon;
    document_employee_number = den;
    document_client_number = dcln;
    document_amount = da;
    document_employee_name = dena;
    document_client_name = dcna;

    document_payment_amount = 0;

    document_activity_hashmap = new HashMap<>();

}

public Document(int dn,boolean dt,boolean ds, long dpa){

    document_number = dn; 
    document_type = dt;
    document_status = ds;

    document_payment_amount = dpa;

    document_activity_hashmap = new HashMap<>();

}

// Print document information 
public void printDocumentInformation (){
    System.out.println("Document Number:" + document_number); 
    System.out.println("Document Date:" + document_date); 
    System.out.println("Document Type:" + document_type); 
    System.out.println("Document Status:" + document_status); 
    System.out.println("Document Statement:" + document_statement); 
    System.out.println("Document Code Number:" + document_code_number); 
    System.out.println("Document Client Number:" + document_client_number); 
    System.out.println("Document Employee Number:" + document_employee_number); 
    System.out.println("Document Amount:" + document_amount); 
    System.out.println("Document Payment Amount:" + document_payment_amount); 
    System.out.println("Document Employee Name:" + document_employee_name); 
    System.out.println("Document Client Name:" + document_client_name); 

} 
} 

Second of all, you can define a class to handle your database needs. For example I defined a class named DataBase.java which handles my connections to the database and my needed queries. And I instantiated an objected of it in my main class.

package financialdocuments;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;

import java.util.logging.Level;
import java.util.logging.Logger;

I hope this could be a little help.

I ended her with the same problem and I could not use the the solution with onEditorAction or onFocusChange and did not want to try the timer. A timer is too dangerous for may taste, because of all the threads and too unpredictable, as you do not know when you code is executed.

The onEditorAction do not catch when the user leave without using a button and if you use it please notice that KeyEvent can be null. The focus is unreliable at both ends the user can get focus and leave without enter any text or selecting the field and the user do not need to leave the last EditText field.

My solution use onFocusChange and a flag set when the user starts editing text and a function to get the text from the last focused view, which I call when need.

I just clear the focus on all my text fields to tricker the leave text view code, The clearFocus code is only executed if the field has focus. I call the function in onSaveInstanceState so I do not have to save the flag (mEditing) as a state of the EditText view and when important buttons is clicked and when the activity is closed.

Be careful with TexWatcher as it is call often I use the condition on focus to not react when the onRestoreInstanceState code entering text. I

final EditText mEditTextView = (EditText) getView();

    mEditTextView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            if (!mEditing && mEditTextView.hasFocus()) {
                mEditing = true;
            }
        }
    });
    mEditTextView.setOnFocusChangeListener(new View.OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus && mEditing) {
                mEditing = false;
                ///Do the thing
            }
        }
    });
protected void saveLastOpenField(){
    for (EditText view:getFields()){
            view.clearFocus();
    }
}

Suppose your drop down list is:

<asp:DropDownList runat="server" id="ddl">
<asp:ListItem Value="0" text="Select a Value">
....
</asp:DropDownList>

There are two ways:

<asp:RequiredFieldValidator ID="re1" runat="Server" InitialValue="0" />

the 2nd way is to use a compare validator:

<asp:CompareValidator ID="re1" runat="Server" ValueToCompare="0" ControlToCompare="ddl" Operator="Equal" />

From the book The Go Programming Language

To remove an element from the middle of a slice, preserving the order of the remaining elements, use copy to slide the higher-numbered elements down by one to fill the gap:

func remove(slice []int, i int) []int {
  copy(slice[i:], slice[i+1:])
  return slice[:len(slice)-1]
}

I bet you have to install libxml2-devel or libxml++-devel or even python-devel. But it is only a wild guess, not seeing the actual error from the log file. But it seems gcc is missing either a header file or a library file.

In this case you are restarting your node.js server often because it's in active development and you are making changes all the time. There is a great hot reload script that will handle this for you by watching all your .js files and restarting your node.js server if any of those files have changed. Just the ticket for rapid development and test.

The script and explanation on how to use it are at here at Draco Blue.

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)

Add the path to where your new library is to LD_LIBRARY_PATH (it has slightly different name on Mac ...)

Your solution should work with using the -L/my/dir -lfoo options, at runtime use LD_LIBRARY_PATH to point to the location of your library.

Careful with using LD_LIBRARY_PATH - in short (from link):

..implications..:
Security: Remember that the directories specified in LD_LIBRARY_PATH get searched before(!) the standard locations? In that way, a nasty person could get your application to load a version of a shared library that contains malicious code! That’s one reason why setuid/setgid executables do neglect that variable!
Performance: The link loader has to search all the directories specified, until it finds the directory where the shared library resides – for ALL shared libraries the application is linked against! This means a lot of system calls to open(), that will fail with “ENOENT (No such file or directory)”! If the path contains many directories, the number of failed calls will increase linearly, and you can tell that from the start-up time of the application. If some (or all) of the directories are in an NFS environment, the start-up time of your applications can really get long – and it can slow down the whole system!
Inconsistency: This is the most common problem. LD_LIBRARY_PATH forces an application to load a shared library it wasn’t linked against, and that is quite likely not compatible with the original version. This can either be very obvious, i.e. the application crashes, or it can lead to wrong results, if the picked up library not quite does what the original version would have done. Especially the latter is sometimes hard to debug.

OR

Use the rpath option via gcc to linker - runtime library search path, will be used instead of looking in standard dir (gcc option):

-Wl,-rpath,$(DEFAULT_LIB_INSTALL_PATH)

This is good for a temporary solution. Linker first searches the LD_LIBRARY_PATH for libraries before looking into standard directories.

If you don't want to permanently update LD_LIBRARY_PATH you can do it on the fly on command line:

LD_LIBRARY_PATH=/some/custom/dir ./fooo

You can check what libraries linker knows about using (example):

/sbin/ldconfig -p | grep libpthread
        libpthread.so.0 (libc6, OS ABI: Linux 2.6.4) => /lib/libpthread.so.0

And you can check which library your application is using:

ldd foo
        linux-gate.so.1 =>  (0xffffe000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb7f9e000)
        libxml2.so.2 => /usr/lib/libxml2.so.2 (0xb7e6e000)
        librt.so.1 => /lib/librt.so.1 (0xb7e65000)
        libm.so.6 => /lib/libm.so.6 (0xb7d5b000)
        libc.so.6 => /lib/libc.so.6 (0xb7c2e000)
        /lib/ld-linux.so.2 (0xb7fc7000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7c2a000)
        libz.so.1 => /lib/libz.so.1 (0xb7c18000)

Try this:

static public string UpperCaseFirstCharacter(this string text) {
    return Regex.Replace(text, "^[a-z]", m => m.Value.ToUpper());
}

This is new thing in C++ 0x standards where you can delete an inherited function.

Rotating the labels is certainly possible. Note though that doing so reduces the readability of the text. One alternative is to alternate label positions using a code like this:

import numpy as np
n=5

x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]


fig, ax = plt.subplots()
ax.plot(x,y, 'o-')
ax.set_xticks(x)
labels = ax.set_xticklabels(xlabels)
for i, label in enumerate(labels):
    label.set_y(label.get_position()[1] - (i % 2) * 0.075)

For more background and alternatives, see this post on my blog

Using Linq ...

List<string> listofIDs = collection.AllKeys.ToList();  
List<int> myStringList = listofIDs.Select(s => int.Parse(s)).ToList();

In urls.py you can override the 3 most important variables:

from django.contrib import admin

admin.site.site_header = 'My project'                    # default: "Django Administration"
admin.site.index_title = 'Features area'                 # default: "Site administration"
admin.site.site_title = 'HTML title from adminsitration' # default: "Django site admin"

Reference: Django documentation on these attributes.

<> will surely give you all values not equal to 5. If you have more than one record in table it will give you all except 5. If on the other hand you have only one, you will get surely one. Give the table schema so that one can help you properly

\usepackage{array} in the preamble

then this:

\begin{tabular}{| >{\centering\arraybackslash}m{1in} | >{\centering\arraybackslash}m{1in} |}

note that the "m" for fixed with column is provided by the array package, and will give you vertical centering (if you don't want this just go back to "p"

Because Google led me here, on Ubuntu 20.04 this works in 2020:

sudo apt install php7.4-xml

If on Apache2, remember to restart (probably not necessary):

sudo systemctl restart apache2

Subclassing in Python is done as follows:

class WindowElement:
    def print(self):
        pass

class Button(WindowElement):
    def print(self):
        pass

Here is a tutorial about Python that also contains classes and subclasses.

I had similar problem with my eclipse maven project. I fought with this issue quite a long time then I tried to rebuild project with

mvn clean eclipse:eclipse

and it helped.

Note: Using this approach will confuse the m2e plugin since the two approaches are very different. m2e adds a virtual node to your project called "Maven Dependencies" and asks Maven to add all dependencies there.

mvn eclipse:eclipse, on the other hand, will create a lot of individual entries in the file .classpath. Eclipse will handle them as if you manually added JARs to your project.

Unless you know how the classpath in Eclipse works, this approach is not recommended.

What operating system are you using? I use Linux Mint. In my case it turned out to be a symbolic link issue. Every time I tried to create the project with the symlink path, it would give me that error. Creating the project elsewhere, and then migrating it to the symlinked directory solved it for me.

Here is another example similar to the previous one, but extended to further demonstrate inflate parameters and dynamic behavior it can provide.

Suppose your ListView row layout can have variable number of TextViews. So first you inflate the base item View (just like the previous example), and then loop dynamically adding TextViews at run-time. Using android:layout_weight additionally aligns everything perfectly.

Here are the Layouts resources:

list_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="horizontal" >
    <TextView 
        android:id="@+id/field1"
        android:layout_width="0dp"  
        android:layout_height="wrap_content" 
        android:layout_weight="2"/>
    <TextView 
        android:id="@+id/field2"
        android:layout_width="0dp"  
        android:layout_height="wrap_content" 
        android:layout_weight="1"
/>
</LinearLayout>

schedule_layout.xml

<?xml version="1.0" encoding="utf-8"?>
   <TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="0dp"  
    android:layout_height="wrap_content" 
    android:layout_weight="1"/>

Override getView method in extension of BaseAdapter class

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = activity.getLayoutInflater();
    View lst_item_view = inflater.inflate(R.layout.list_layout, null);
    TextView t1 = (TextView) lst_item_view.findViewById(R.id.field1);
    TextView t2 = (TextView) lst_item_view.findViewById(R.id.field2);
    t1.setText("some value");
    t2.setText("another value");

    // dinamically add TextViews for each item in ArrayList list_schedule
    for(int i = 0; i < list_schedule.size(); i++){
        View schedule_view = inflater.inflate(R.layout.schedule_layout, (ViewGroup) lst_item_view, false);
        ((TextView)schedule_view).setText(list_schedule.get(i));
        ((ViewGroup) lst_item_view).addView(schedule_view);
    }
    return lst_item_view;
}

Note different inflate method calls:

inflater.inflate(R.layout.list_layout, null); // no parent
inflater.inflate(R.layout.schedule_layout, (ViewGroup) lst_item_view, false); // with parent preserving LayoutParams

You can access keys in the App.Config using:

ConfigurationSettings.AppSettings["KeyName"]

Take alook at this Thread

You can use a LENGTH(that_string) minus the number of characters you want to remove in the SUBSTRING() select perhaps or use the TRIM() function.

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

In theory your router should be able to tell you the public IP address of the network, but the way of doing this will necessarily be inconsistent/non-straightforward, if even possible with some router devices.

The easiest and still a very reliable method is to send a request to a web page that returns your IP address as the web server sees it. Dyndns.org provides a good service for this:

http://checkip.dyndns.org/

What is returned is an extremely simple/short HTML document, containing the text Current IP Address: 157.221.82.39 (fake IP), which is trivial to extract from the HTTP response.

Use Measure-Command

Example

Measure-Command { <your command here> | Out-Host }

The pipe to Out-Host allows you to see the output of the command, which is otherwise consumed by Measure-Command.

If you're calling ProgressDialog.show() in a fragment, casting the mContext to Activity worked for me.

     ProgressDialog pd = new ProgressDialog((Activity) mContext);

If you have changed innodb_log_file_size recently, try to restore the previous value which worked.

The API >= 11 solution:

You can integrate the padding into divider. In case you were using none, just create a tall empty drawable and set it as LinearLayout's divider:

    <LinearLayout
            android:showDividers="middle"
            android:divider="@drawable/empty_tall_divider"
...>...</LinearLayout>

empty_tall_divider.xml:

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

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <size
            android:height="40dp"
            android:width="0dp"/>
</shape>

Adding on to @Rob Hruska's sol, this setting in server.xml inside section works:

<Context path="" docBase="gateway" reloadable="true" override="true"> </Context>

Note: override="true" might be required in some cases.

this isn't a css selector. you can avoid spelling the id of this by passing it as a context:

$('option:selected', this).remove();

http://api.jquery.com/jQuery/

NR starts at 1, so use

awk '{print NR-1 "," $0}'

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

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

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

Summary: check your query for double single quotes.

You should consider passing the -P argument in invoking Gradle.

From Gradle Documentation :

--project-prop Sets a project property of the root project, for example -Pmyprop=myvalue. See Section 14.2, “Gradle properties and system properties”.

Considering this build.gradle

task printProp << {
    println customProp
}

Invoking Gradle -PcustomProp=myProp will give this output :

$ gradle -PcustomProp=myProp printProp
:printProp
myProp

This is the way I found to pass parameters.

Assuming your json object from your GET request looks like the one you posted above simply do:

let list: string[] = [];

json.Results.forEach(element => {
    list.push(element.Id);
});

Or am I missing something that prevents you from doing it this way?

Applies to .NET Core 1 and .Net Core 2 (further down)

If using .Net-Core 1.1

Unfortunately the docs are very confusing in this specific case. So I'll make it dead-simple:

• Add Microsoft.AspNetCore.Cors nuget package to your project
• In ConfigureServices method, add services.AddCors();

• In Configure method, before calling app.UseMvc() and app.UseStaticFiles(), add:

  app.UseCors(builder => builder
      .AllowAnyOrigin()
      .AllowAnyMethod()
      .AllowAnyHeader()
      .AllowCredentials());
  

That's it. Every client has access to your ASP.NET Core Website/API.

If using .Net-Core 2.0

• Add Microsoft.AspNetCore.Cors nuget package to your project

• in ConfigureServices method, before calling services.AddMvc(), add:

   services.AddCors(options =>
      {
          options.AddPolicy("AllowAll",
              builder =>
              {
                  builder
                  .AllowAnyOrigin() 
                  .AllowAnyMethod()
                  .AllowAnyHeader()
                  .AllowCredentials();
              });
      });
  

• (Important) In Configure method, before calling app.UseMvc(), add app.UseCors("AllowAll");

  AllowAll is the policy name which we need to mention in app.UserCors. It could be any name.

Some interesting alternatives:

OPTION 1

PrintStream p = System.out;
p.println("hello");

OPTION 2

PrintWriter p = new PrintWriter(System.out, true);
p.println("Hello");

I know this is old and that this is a little off topic, but supposing you wanted to uncheck only specific radio buttons in a collection:

$("#go").click(function(){_x000D_
    $("input[name='correctAnswer']").each(function(){_x000D_
      if($(this).val() !== "1"){_x000D_
        $(this).prop("checked",false);_x000D_
      }_x000D_
    });_x000D_
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<input id="radio1" type="radio" name="correctAnswer" value="1">1</input>_x000D_
<input id="radio2" type="radio" name="correctAnswer" value="2">2</input>_x000D_
<input id="radio3" type="radio" name="correctAnswer" value="3">3</input>_x000D_
<input id="radio4" type="radio" name="correctAnswer" value="4">4</input>_x000D_
<input type="button" id="go" value="go">

And if you are dealing with a radiobutton list, you can use the :checked selector to get just the one you want.

$("#go").click(function(){
  $("input[name='correctAnswer']:checked").prop("checked",false);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input id="radio1" type="radio" name="correctAnswer" value="1">1</input>
<input id="radio2" type="radio" name="correctAnswer" value="2">2</input>
<input id="radio3" type="radio" name="correctAnswer" value="3">3</input>
<input id="radio4" type="radio" name="correctAnswer" value="4">4</input>
<input type="button" id="go" value="go">

Yes, that is one way to get the first line of output from a command.

If the command outputs anything to standard error that you would like to capture in the same manner, you need to redirect the standard error of the command to the standard output stream:

utility 2>&1 | head -n 1

There are many other ways to capture the first line too, including sed 1q (quit after first line), sed -n 1p (only print first line, but read everything), awk 'FNR == 1' (only print first line, but again, read everything) etc.

For certain html fragments like <td>test</td>, div.innerHTML, DOMParser.parseFromString and range.createContextualFragment (without the right context) solutions mentioned in other answers here, won't create the <td> element.

jQuery.parseHTML() handles them properly (I extracted jQuery 2's parseHTML function into an independent function that can be used in non-jquery codebases).

If you are only supporting Edge 13+, it is simpler to just use the HTML5 template tag:

function parseHTML(html) {
    var t = document.createElement('template');
    t.innerHTML = html;
    return t.content.cloneNode(true);
}

var documentFragment = parseHTML('<td>Test</td>');

x^y is not "x to the power of y". It's "x XOR y".

Add a class:

.com_box:after {
     content: '';
    position: absolute;
    left: 18px;
    top: 50px;
    width: 0;
    height: 0;
    border-left: 20px solid transparent;
    border-right: 20px solid transparent;
    border-top: 20px solid #000;
    clear: both;

}

Yes, you should always use semicolons. Why? Because if you end up using a JavaScript compressor, all your code will be on one line, which will break your code.

Try http://www.jslint.com/; it will hurt your feelings, but show you many ways to write better JavaScript (and one of the ways is to always use semicolons).

On my CentOS 6 I have two openssl.cnf :

/openvpn/easy-rsa/
/pki/tls/

You need to close all your connexions for example: If you make an INSERT INTO statement you need to close the statement and your connexion in this way:

statement.close();
Connexion.close():

And if you make a SELECT statement you need to close the statement, the connexion and the resultset in this way:

resultset.close();
statement.close();
Connexion.close();

I did this and it worked

i came across a similar situation using booleans where I wanted to avoid calling b() if a was already false.

This worked for me:

a &= a && b()

To hide from the UI, use Format > Sheet > Hide

To hide programatically, use the Visible property of the Worksheet object. If you do it programatically, you can set the sheet as "very hidden", which means it cannot be unhidden through the UI.

ActiveWorkbook.Sheets("Name").Visible = xlSheetVeryHidden 
' or xlSheetHidden or xlSheetVisible

You can also set the Visible property through the properties pane for the worksheet in the VBA IDE (ALT+F11).

I just placed a short-cut to the XAMPP control panel in my startup folder. That works just fine on Window 7. Start -> All Programs -> Startup. There is also an option to start XAMPP control panel minimized, that is very useful for getting a clean unobstructed view of your desktop at start-up.**

I was looking around for an answer on bulk inserting Objects.

The answer by Ragnar123 led me to making this function:

function bulkInsert(connection, table, objectArray, callback) {
  let keys = Object.keys(objectArray[0]);
  let values = objectArray.map( obj => keys.map( key => obj[key]));
  let sql = 'INSERT INTO ' + table + ' (' + keys.join(',') + ') VALUES ?';
  connection.query(sql, [values], function (error, results, fields) {
    if (error) callback(error);
    callback(null, results);
  });
}

bulkInsert(connection, 'my_table_of_objects', objectArray, (error, response) => {
  if (error) res.send(error);
  res.json(response);
});

Hope it helps!

Assuming that the DropDownList control in the other table also contains DepartmentName and DepartmentID:

lstDepartment.ClearSelection();

foreach (var item in lstDepartment.Items) 
{
  if (item.Value == otherDropDownList.SelectedValue)
  {
    item.Selected = true;
  }
}

You can get maximum column value and increment it:

InnoDB uses the following algorithm to initialize the auto-increment counter for a table t that contains an AUTO_INCREMENT column named ai_col: After a server startup, for the first insert into a table t, InnoDB executes the equivalent of this statement:

SELECT MAX(ai_col) FROM t FOR UPDATE;

InnoDB increments by one the value retrieved by the statement and assigns it to the column and to the auto-increment counter for the table. If the table is empty, InnoDB uses the value 1.

Also you can use SHOW TABLE STATUS and its "Auto_increment" value.

As an addendum to the other answers, this sounds like a fine use-case for a context manager that will re-map the names of these functions to ones which return a list and introduce reduce in the global namespace.

A quick implementation might look like this:

from contextlib import contextmanager    

@contextmanager
def noiters(*funcs):
    if not funcs: 
        funcs = [map, filter, zip] # etc
    from functools import reduce
    globals()[reduce.__name__] = reduce
    for func in funcs:
        globals()[func.__name__] = lambda *ar, func = func, **kwar: list(func(*ar, **kwar))
    try:
        yield
    finally:
        del globals()[reduce.__name__]
        for func in funcs: globals()[func.__name__] = func

With a usage that looks like this:

with noiters(map):
    from operator import add
    print(reduce(add, range(1, 20)))
    print(map(int, ['1', '2']))

Which prints:

190
[1, 2]

Just my 2 cents :-)

A method has already been devised, however this way you don't need a temp file.

for /f "delims=" %%i in ('command') do set output=%%i

However, I'm sure this has its own exceptions and limitations.

There is a way with struct namespace.

The benefit is all enum variables are under a specific namespace to avoid pollution. The issue is that we could only use var not const

type OrderStatusType string

var OrderStatus = struct {
    APPROVED         OrderStatusType
    APPROVAL_PENDING OrderStatusType
    REJECTED         OrderStatusType
    REVISION_PENDING OrderStatusType
}{
    APPROVED:         "approved",
    APPROVAL_PENDING: "approval pending",
    REJECTED:         "rejected",
    REVISION_PENDING: "revision pending",
}

So you are asking for a very core reason?

Well, since you are developing in Java, the compiler generates an object code that the Java Virtual Machine can interpret. The JVM anyway is a binary program that run in machine language (probably the JVM’s version specific for your operating system and hardware was previously compiled by another programming language like C in order to get a machine code that can run in your processor). At the end, any code is translated to machine code. So, create an object (an instance of a class) is equivalent to reserve a memory space (memory registers that will be processor registers when the CPU scheduler of the operating system put your program at the top of the queue in order to execute it) to have a data storage place that can be able to read and write data. If you don’t have an instance of a class (which happens on a static context), then you don’t have that memory space to read or write the data. In fact, like other people had said, the data don’t exist (because from the begin you never had written neither had reserved the memory space to store it).

Sorry for my english! I'm latin!

Using the JSON.NET NuGet package and anonymous types, you can simplify what the other posters are suggesting:

// ...

string payload = JsonConvert.SerializeObject(new
{
    agent = new
    {
        name    = "Agent Name",
        version = 1,
    },

    username = "username",
    password = "password",
    token    = "xxxxx",
});

var client = new HttpClient();
var content = new StringContent(payload, Encoding.UTF8, "application/json");

HttpResponseMessage response = await client.PostAsync(uri, content);

// ...

Considering that the accepted answer is probably inefficient for large arrays, O(nm), I usually prefer this approach, O(2n + 2m):

function mergeArrays(arr1 = [], arr2 = []){
    //Creates an object map of id to object in arr1
    const arr1Map = arr1.reduce((acc, o) => {
        acc[o.id] = o;
        return acc;
    }, {});
    //Updates the object with corresponding id in arr1Map from arr2, 
    //creates a new object if none exists (upsert)
    arr2.forEach(o => {
        arr1Map[o.id] = o;
    });

    //Return the merged values in arr1Map as an array
    return Object.values(arr1Map);
}

Unit test:

it('Merges two arrays using id as the key', () => {
   var arr1 = [{id:'124',name:'qqq'}, {id:'589',name:'www'}, {id:'45',name:'eee'}, {id:'567',name:'rrr'}];
   var arr2 = [{id:'124',name:'ttt'}, {id:'45',name:'yyy'}];
   const actual = mergeArrays(arr1, arr2);
   const expected = [{id:'124',name:'ttt'}, {id:'589',name:'www'}, {id:'45',name:'yyy'}, {id:'567',name:'rrr'}];
   expect(actual.sort((a, b) => (a.id < b.id)? -1: 1)).toEqual(expected.sort((a, b) => (a.id < b.id)? -1: 1));
})

If you are limited to ES6, the best option is Promise all. Promise.all(array) also returns an array of promises after successfully executing all the promises in array argument. Suppose, if you want to update many student records in the database, the following code demonstrates the concept of Promise.all in such case-

let promises = students.map((student, index) => {
//where students is a db object
student.rollNo = index + 1;
student.city = 'City Name';
//Update whatever information on student you want
return student.save();
});
Promise.all(promises).then(() => {
  //All the save queries will be executed when .then is executed
  //You can do further operations here after as all update operations are completed now
});

Map is just an example method for loop. You can also use for or forin or forEach loop. So the concept is pretty simple, start the loop in which you want to do bulk async operations. Push every such async operation statement in an array declared outside the scope of that loop. After the loop completes, execute the Promise all statement with the prepared array of such queries/promises as argument.

The basic concept is that the javascript loop is synchronous whereas database call is async and we use push method in loop that is also sync. So, the problem of asynchronous behavior doesn't occur inside the loop.

i basically suggest equal gap on right and left, and setting width to auto. Here like:

.bmi {         /*my additional class name -for card*/
    margin-left: 18%;      
    margin-right: 18%;
    width: auto;
}
