Programs & Examples On #Boundfield

Before data bind change gridview databinding method, assign GridView.EditIndex to -1. It solved the same issue for me :

 gvTypes.EditIndex = -1;
 gvTypes.DataBind();

gvTypes is my GridView ID.

Formatting depends on the server's culture setting. If you use en-US culture, you can use Short Date Pattern like {0:d}

For example, it formats 6/15/2009 1:45:30 to 6/15/2009

You can check more formats from BoundField.DataFormatString

Just for the record, I got borders in the table and to get rid of it I needed to set following properties in the GridView:

GridLines="None"
CellSpacing="-1"

     <asp:TemplateField HeaderText="ExEmp" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"
                                                                    FooterStyle-BackColor="BurlyWood" FooterStyle-HorizontalAlign="Center">
                                                                    <ItemTemplate>
                                                                        <asp:TextBox ID="txtNoOfExEmp" runat="server" CssClass="form-control input-sm m-bot15"
                                                                            Font-Bold="true" onkeypress="return isNumberKey(event)" Text='<%#Bind("ExEmp") %>'></asp:TextBox>
                                                                    </ItemTemplate>
                                                                    <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                                                                    <ItemStyle HorizontalAlign="Center" Width="50px" />
                                                                    <FooterTemplate>
                                                                        <asp:Label ID="lblTotNoOfExEmp" Font-Bold="true" runat="server" Text="0" CssClass="form-label"></asp:Label>
                                                                    </FooterTemplate>
                                                                </asp:TemplateField>


 private void TotalExEmpOFMonth()
    {
        Label lbl_TotNoOfExEmp = (Label)GrdPFRecord.FooterRow.FindControl("lblTotNoOfExEmp");
        /*Sum of the  Total Amount Of month*/
        foreach (GridViewRow gvr in GrdPFRecord.Rows)
        {
            TextBox txt_NoOfExEmp = (TextBox)gvr.FindControl("txtNoOfExEmp");
            lbl_TotNoOfExEmp.Text = (Convert.ToDouble(txt_NoOfExEmp.Text) + Convert.ToDouble(lbl_TotNoOfExEmp.Text)).ToString();
            lbl_TotNoOfExEmp.Text = string.Format("{0:F0}", Decimal.Parse(lbl_TotNoOfExEmp.Text));



        }
    }

add HeaderStyle in your bound field:

    <asp:BoundField HeaderText="UserId"
                DataField="UserId" 
                SortExpression="UserId">

                <HeaderStyle Width="200px" />

</asp:BoundField>

Try This Make sure You mention Datakeyname which is nothing but the column name (id) in your designer file

//your aspx code

<asp:GridView ID="dgUsers" runat="server" AutoGenerateSelectButton="True" OnDataBound="dgUsers_DataBound" OnRowDataBound="dgUsers_RowDataBound" OnSelectedIndexChanged="dgUsers_SelectedIndexChanged" AutoGenerateDeleteButton="True" OnRowDeleting="dgUsers_RowDeleting" DataKeyNames="id" OnRowCommand="dgUsers_RowCommand"></asp:GridView>

//Your aspx.cs Code

protected void dgUsers_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {

            int id = Convert.ToInt32(dgUsers.DataKeys[e.RowIndex].Value);
            string query = "delete from users where id= '" + id + "'";
            //your remaining delete code
        }

you have to iterate gridview Rows

for (int count = 0; count < grd.Rows.Count; count++)
{
    if (((CheckBox)grd.Rows[count].FindControl("yourCheckboxID")).Checked)
    {     
      ((Label)grd.Rows[count].FindControl("labelID")).Text
    }
}

If I am not mistaken, GridView does not hold the values of BoundColumns that have the attribute visible="false". Two things you may do here, one (as explained in the answer from V4Vendetta) to use Datakeys. Or you can change your BoundColumn to a TemplateField. And in the ItemTemplate, add a control like Label, make its visibility false and give your value to that Label.

A simple solution:

protected SortDirection GetSortDirection(string column)
{
    SortDirection nextDir = SortDirection.Ascending; // Default next sort expression behaviour.
    if (ViewState["sort"] != null && ViewState["sort"].ToString() == column)
    {   // Exists... DESC.
        nextDir = SortDirection.Descending;
        ViewState["sort"] = null;
    }
    else
    {   // Doesn't exists, set ViewState.
        ViewState["sort"] = column;
    }
    return nextDir;
}

Much like the default GridView sorting and lightweight on the ViewState.

USAGE:

protected void grdHeader_OnSorting(object sender, GridViewSortEventArgs e)
{
    List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection();

    items.Sort(new Helpers.GenericComparer<V_ReportPeriodStatusEntity>(e.SortExpression, GetSortDirection(e.SortExpression));
    grdHeader.DataSource = items;
    grdHeader.DataBind();
}

Add a method to your page class like this:

public string YesNo(bool active) 
{
  return active ? "Yes" : "No";
}

And then in your TemplateField you Bind using this method:

<%# YesNo(Active) %>

Use JSON_UNESCAPED_UNICODE inside json_encode() if your php version >=5.4.

Well,

Just worked it out. While having both installations we have two ORACLE_HOME directories and both have SQAORA32.dll files. While looking up for ORACLE_HOMe my app was getting confused..I just removed the Client oracle home entry as oracle client is by default present in oracle DB Now its working...Thanks!!

What if you make use of procedural function instead of variable and call them any where as you.

I usually make a collection of configuration values and put them inside a function with return statement. I just include that where I need to make use of global value and call particular function.

function host()
{
   return "localhost";
}

I wrote an updated version of Kees C. Bakker's answer:

const hasVerticalScroll = (node) => {
  if (!node) {
    if (window.innerHeight) {
      return document.body.offsetHeight > window.innerHeight
    }
    return (document.documentElement.scrollHeight > document.documentElement.offsetHeight)
      || (document.body.scrollHeight > document.body.offsetHeight)
  }
  return node.scrollHeight > node.offsetHeight
}

if (hasVerticalScroll(document.querySelector('body'))) {
  this.props.handleDisableDownScrollerButton()
}

The function returns true or false depending whether the page has a vertical scrollbar or not.

For example:

const hasVScroll = hasVerticalScroll(document.querySelector('body'))

if (hasVScroll) {
  console.log('HAS SCROLL', hasVScroll)
}

you can use autocomplete="off" on parent form, so if you reload your page, checkboxes will not be checked automatically

My two cents: came across the same error message in RHEL7.3 while running the openssl command with root CA certificate. The reason being, while downloading the certificate from AD server, Encoding was selected as DER instead of Base64. Once the proper version of encoding was selected for the new certificate download, error was resolved

Hope this helps for new users :-)

Well, better late than never. Google maps API v3 now provides address autocompletion.

API docs are here: http://code.google.com/apis/maps/documentation/javascript/reference.html#Autocomplete

A good example is here: http://code.google.com/apis/maps/documentation/javascript/examples/places-autocomplete.html

You can use RegExMatch:

=IF(RegExMatch(A1;"Bla");"YES";"NO")

numbers = [1, 2, 3]
numsum = sum(list(numbers))
print(numsum)

This would work, if your are trying to Sum up a list.

select @i:=uuid();
update some_table set guid = (@i:=uuid());

Do this.

var x=parseInt(document.forms["frmOrder"]["txtTotal"].value);
var y=parseInt(document.forms["frmOrder"]["totalpoints"].value);

To explicitly checkout using a specific credentials

    stage('Checkout external proj') {
        steps {
            git branch: 'my_specific_branch',
                credentialsId: 'my_cred_id',
                url: 'ssh://[email protected]/proj/test_proj.git'

            sh "ls -lat"
        }
    }

To checkout based on the configred credentials in the current Jenkins Job

    stage('Checkout code') {
        steps {
            checkout scm
        }
    }

You can use both of the stages within a single Jenkins file.

Someone here suggested using eval() to remove the quotes from a string. Don't do that, that's just begging for code injection.

Another way to do this that I don't see listed here is using:

let message = JSON.stringify(your_json_here); // "Hello World"
console.log(JSON.parse(message))              // Hello World

In general:

Database and table names are not case sensitive in Windows, and case sensitive in most varieties of Unix.

In MySQL, databases correspond to directories within the data directory. Each table within a database corresponds to at least one file within the database directory. Consequently, the case sensitivity of the underlying operating system plays a part in the case sensitivity of database and table names.

One can configure how tables names are stored on the disk using the system variable lower_case_table_names (in the my.cnf configuration file under [mysqld]).

Read the section: 10.2.2 Identifier Case Sensitivity for more information.

As a python3 user,

The difference between load and loads methods is important especially when you read json data from file.

As stated in the docs:

json.load:

Deserialize fp (a .read()-supporting text file or binary file containing a JSON document) to a Python object using this conversion table.

json.loads:

json.loads: Deserialize s (a str, bytes or bytearray instance containing a JSON document) to a Python object using this conversion table.

json.load method can directly read opened json document since it is able to read binary file.

with open('./recipes.json') as data:
  all_recipes = json.load(data)

As a result, your json data available as in a format specified according to this conversion table:

https://docs.python.org/3.7/library/json.html#json-to-py-table

hey there go to GITHUB link here(https://github.com/joonro/Spyder-Color-Themes) do as the page says u can get the stunning tomorrow night theme

Similar to the first example, but with more flexibility:

-- min_length = 8, max_length = 12
SET @Length = RAND() * 5 + 8
-- SET @Length = RAND() * (max_length - min_length + 1) + min_length

-- define allowable character explicitly - easy to read this way an easy to 
-- omit easily confused chars like l (ell) and 1 (one) or 0 (zero) and O (oh)
SET @CharPool = 
    'abcdefghijkmnopqrstuvwxyzABCDEFGHIJKLMNPQRSTUVWXYZ23456789.,-_!$@#%^&*'
SET @PoolLength = Len(@CharPool)

SET @LoopCount = 0
SET @RandomString = ''

WHILE (@LoopCount < @Length) BEGIN
    SELECT @RandomString = @RandomString + 
        SUBSTRING(@Charpool, CONVERT(int, RAND() * @PoolLength) + 1, 1)
    SELECT @LoopCount = @LoopCount + 1
END

I forgot to mention one of the other features that makes this more flexible. By repeating blocks of characters in @CharPool, you can increase the weighting on certain characters so that they are more likely to be chosen.

Try this:

DateFormat.parse(String)

It's very simple.

1. You add an image.

2. You create a css property to this image.

   img { transition: all 0.3s ease-in-out 0s; }
   

3. You add an animation like that:

   img:hover
   {
       cursor: default;
       transform: rotate(360deg);
       transition: all 0.3s ease-in-out 0s;
   }
   

I'm not sure if this is the fastest solution, but it looks like it is the shortest one:

$result = current(explode("\n", wordwrap($str, $width, "...\n")));

P.S. See some examples here https://stackoverflow.com/a/17852480/131337

I am sorry if i am late to reply here but i just thought i should throw in a much simpler solution for the OpenDialog.

OpenDialog ofd = new OpenDialog();
var fullPathIncludingFileName = ofd.Filename; //returns the full path including the filename
var fullPathExcludingFileName = ofd.Filename.Replace(ofd.SafeFileName, "");//will remove the filename from the full path

I have not yet used a FolderBrowserDialog before so i will trust my fellow coders's take on this. I hope this helps.

(1) You can also use gradle commands to install your APK while choosing the product and flavor (Debug or Release). See this Guide.

./gradlew assembleDebug (Incase you don't have the APK generated)


./gradlew installDebug

Incase you want a fresh install, you can remove any earlier installed builds on the device with below commands

./gradlew uninstallDebug
./gradlew installDebug

(2) You can also use the adb commands directly:

Setup adb for command line

export PATH=/Users/mayurik/Library/Android/sdk/platform-tools/adb:/Users/mayurik/Library/Android/sdk/tool

Command line ADB install

adb -d install pathto/sample.apk (on device)
adb -e install pathto/sample.apk (on emulator)

Also check the documentation here

$ adb devices
List of devices attached
emulator-5554 device
emulator-5555 device

$ adb -s emulator-5555 install helloWorld.apk

echo $this->db->select('title, content, date')->get_compiled_select();

I think the following is the simplest solution which allows for a given length:

Array(myLength).fill(0).map(x => Math.random().toString(36).charAt(2)).join('')

It depends on the arrow function syntax.

In Place of using this

MsgBox(json.SelectToken("Venue").SelectToken("ID"))

You can also use

MsgBox(json.SelectToken("Venue.ID"))

Find:

^[#;].*

Replace with nothing. The ^ indicates the start of a line, the [#;] is a character class to match either # or ;, and .* matches anything else in the line.

In versions of Notepad++ before 6.0, you won't be able to actually remove the lines due to a limitation in its regex engine; the replacement results in blank lines for each line matched. In other words, this:

# foo
; bar
statement;

Will turn into:

statement;

However, the replacement will work in Notepad++ 6.0 if you add \r, \n or \r\n to the end of the pattern, depending on which line ending your file is using, resulting in:

statement;

Change the Platform of your C++ project to "x64" (or whichever platform you are targeting) instead of "Win32". This can be found in Visual Studio under Build -> Configuration Manager. Find your project in the list and change the Platform column. Don't forget to do this for all solution configurations.

If an element has bootstrap's "hide" class and you want to display it with some sliding effect such as .slideDown(), you can cheat bootstrap like:

$('#hiddenElement').hide().removeClass('hide').slideDown('fast')

You should try this one :

task getDeps(type: Copy) {
    from configurations.runtime
    into 'runtime/'
}

I was was looking for it some time ago when working on a project in which we had to download all dependencies into current working directory at some point in our provisioning script. I guess you're trying to achieve something similar.

If htaccess is an option this will make all PDF links download instead of opening in browser

<FilesMatch "\.(?i:pdf)$">
  ForceType application/octet-stream
  Header set Content-Disposition attachment
</FilesMatch>

Even though too much of CLOSE_WAIT connections means there is something wrong with your code in the first and this is accepted not good practice.

You might want to check out: https://github.com/rghose/kill-close-wait-connections

What this script does is send out the ACK which the connection was waiting for.

This is what worked for me.

In most software that generates RSA private keys, including openssl's, the private key is represented as a PKCS#1 RSAPrivatekey object or some variant thereof:

A.1.2 RSA private key syntax

An RSA private key should be represented with the ASN.1 type
RSAPrivateKey:

  RSAPrivateKey ::= SEQUENCE {
      version           Version,
      modulus           INTEGER,  -- n
      publicExponent    INTEGER,  -- e
      privateExponent   INTEGER,  -- d
      prime1            INTEGER,  -- p
      prime2            INTEGER,  -- q
      exponent1         INTEGER,  -- d mod (p-1)
      exponent2         INTEGER,  -- d mod (q-1)
      coefficient       INTEGER,  -- (inverse of q) mod p
      otherPrimeInfos   OtherPrimeInfos OPTIONAL
  }

As you can see, this format has a number of fields including the modulus and public exponent and thus is a strict superset of the information in an RSA public key.

if your has this error that "supported Gradle version is 2.14.1. Current version is 2.4. ", on terminal. means your should update your gradle.

On Mac OS: you can use brew upgrade gradle

A dplyr solution:

Idea:

• add rowids as a column
• reshape to long format
• filter for max in each group

Code:

DF = data.frame(V1=c(2,8,1),V2=c(7,3,5),V3=c(9,6,4))
DF %>% 
  rownames_to_column() %>%
  gather(column, value, -rowname) %>%
  group_by(rowname) %>% 
  filter(rank(-value) == 1) 

Result:

# A tibble: 3 x 3
# Groups:   rowname [3]
  rowname column value
  <chr>   <chr>  <dbl>
1 2       V1         8
2 3       V2         5
3 1       V3         9

This approach can be easily extended to get the top n columns. Example for n=2:

DF %>% 
  rownames_to_column() %>%
  gather(column, value, -rowname) %>%
  group_by(rowname) %>% 
  mutate(rk = rank(-value)) %>%
  filter(rk <= 2) %>% 
  arrange(rowname, rk) 

Result:

# A tibble: 6 x 4
# Groups:   rowname [3]
  rowname column value    rk
  <chr>   <chr>  <dbl> <dbl>
1 1       V3         9     1
2 1       V2         7     2
3 2       V1         8     1
4 2       V3         6     2
5 3       V2         5     1
6 3       V3         4     2

Yes, Spring framework logging is very detailed, You did not mention in your post, if you are already using a logging framework or not. If you are using log4j then just add spring appenders to the log4j config (i.e to log4j.xml or log4j.properties), If you are using log4j xml config you can do some thing like this

<category name="org.springframework.beans">
    <priority value="debug" />
</category>

or

<category name="org.springframework">
    <priority value="debug" />
</category>

I would advise you to test this problem in isolation using JUnit test, You can do this by using spring testing module in conjunction with Junit. If you use spring test module it will do the bulk of the work for you it loads context file based on your context config and starts container so you can just focus on testing your business logic. I have a small example here

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:springContext.xml"})
@Transactional
public class SpringDAOTest 
{
    @Autowired
    private SpringDAO dao;

    @Autowired
    private ApplicationContext appContext;

    @Test
    public void checkConfig()
    {
        AnySpringBean bean =  appContext.getBean(AnySpringBean.class);
        Assert.assertNotNull(bean);
    }
}

UPDATE

I am not advising you to change the way you load logging but try this in your dev environment, Add this snippet to your web.xml file

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/log4j.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

UPDATE log4j config file

I tested this on my local tomcat and it generated a lot of logging on application start up. I also want to make a correction: use debug not info as @Rayan Stewart mentioned.

I had the same problem, and didn´t want to rewrite the code, so I wrote a function to modify the code and create the inline declarated events:

function compile(qSel){
    var matches = [];
    var match = null;
    var c = 0;

    var html = $(qSel).html();
    var pattern = /(<(.*?)on([a-zA-Z]+)\s*=\s*('|")(.*)('|")(.*?))(>)/mg;

    while (match = pattern.exec(html)) {
        var arr = [];
        for (i in match) {
            if (!isNaN(i)) {
                arr.push(match[i]);
            }
        }
        matches.push(arr);
    }
    var items_with_events = [];
    var compiledHtml = html;

    for ( var i in matches ){
        var item_with_event = {
            custom_id : "my_app_identifier_"+i,
            code : matches[i][5],
            on : matches[i][3],
        };
        items_with_events.push(item_with_event);
        compiledHtml = compiledHtml.replace(/(<(.*?)on([a-zA-Z]+)\s*=\s*('|")(.*)('|")(.*?))(>)/m, "<$2 custom_id='"+item_with_event.custom_id+"' $7 $8");
    }

    $(qSel).html(compiledHtml);

    for ( var i in items_with_events ){
        $("[custom_id='"+items_with_events[i].custom_id+"']").bind(items_with_events[i].on, function(){
            eval(items_with_events[i].code);
        });
    }
}

$(document).ready(function(){
    compile('#content');
})

This should remove all inline events from the selected node, and recreate them with jquery instead.

I believe that the configure method expects an absolute path. Anyhow, you may also try to load a Properties object first:

Properties props = new Properties();
props.load(new FileInputStream("log4j.properties"));
PropertyConfigurator.configure(props);

If the properties file is in the jar, then you could do something like this:

Properties props = new Properties();
props.load(getClass().getResourceAsStream("/log4j.properties"));
PropertyConfigurator.configure(props);

The above assumes that the log4j.properties is in the root folder of the jar file.

IIS express configuration is managed by applicationhost.config.
You can find it in

Users\<username>\Documents\IISExpress\config folder.

Inside you can find the sites section that hold a section for each IIS Express configured site.

Add (or modify) a site section like this:

<site name="WebSiteWithVirtualDirectory" id="20">
   <application path="/" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="c:\temp\website1" />
   </application>
   <application path="/OffSiteStuff" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="d:\temp\SubFolderApp" />
   </application>
    <bindings>
      <binding protocol="http" bindingInformation="*:1132:localhost" />
   </bindings>
</site>

Practically you need to add a new application tag in your site for each virtual directory. You get a lot of flexibility because you can set different configuration for the virtual directory (for example a different .Net Framework version)

EDIT Thanks to Fevzi Apaydin to point to a more elegant solution.

You can achieve same result by adding one or more virtualDirectory tag to the Application tag:

<site name="WebSiteWithVirtualDirectory" id="20">
   <application path="/" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="c:\temp\website1" />
     <virtualDirectory path="/OffSiteStuff" physicalPath="d:\temp\SubFolderApp" />
   </application>
    <bindings>
      <binding protocol="http" bindingInformation="*:1132:localhost" />
   </bindings>
</site>

Reference:

• Application tag for a Site
• Virtual Directory tag

An alternative approach would be:

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x4"))

df = df1.join(df2, ['x1','x2'])
df.show()

which outputs:

+---+---+---+---+
| x1| x2| x3| x4|
+---+---+---+---+
|  2|  b|3.0|0.0|
+---+---+---+---+

With the main advantage being that the columns on which the tables are joined are not duplicated in the output, reducing the risk of encountering errors such as org.apache.spark.sql.AnalysisException: Reference 'x1' is ambiguous, could be: x1#50L, x1#57L.

Whenever the columns in the two tables have different names, (let's say in the example above, df2 has the columns y1, y2 and y4), you could use the following syntax:

df = df1.join(df2.withColumnRenamed('y1','x1').withColumnRenamed('y2','x2'), ['x1','x2'])

Above method is working, but here are more realistic slide up and slide down animations from the top of the screen.

Just create these two animations under the anim folder

slide_down.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromYDelta="-100%"
        android:toYDelta="0" />
</set> 

slide_up.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromYDelta="0"
        android:toYDelta="-100%" />
</set>

Load animation in java class like this

imageView.startAnimation(AnimationUtils.loadAnimation(getContext(),R.anim.slide_up));
imageView.startAnimation(AnimationUtils.loadAnimation(getContext(),R.anim.slide_down));

To do that, you must remove all ' charachters in your string or use an escape character. Like:

<?php
    echo '<?php
              echo \'hello world\';
          ?>';
?>

Based on @pymarco answer I wrote this solution, it's not perfect but solves the select2 focus problem and maintain tab sequence working inside modal

    $.fn.modal.Constructor.prototype.enforceFocus = function () {
        $(document)
        .off('focusin.bs.modal') // guard against infinite focus loop
        .on('focusin.bs.modal', $.proxy(function (e) {
            if (this.$element[0] !== e.target && !this.$element.has(e.target).length && !$(e.target).closest('.select2-dropdown').length) {
                this.$element.trigger('focus')
            }
        }, this))
    }

Check: key = undef !!!

You got also the warn message:

Each child in a list should have a unique "key" prop.

if your code is complete right, but if on

<MyComponent key={someValue} />

someValue is undefined!!! Please check this first. You can save hours.

In C++, there is no difference in main() and main(void).

But in C, main() will be called with any number of parameters.

Example:

main ( ){
    main(10,"abc",12.28);
    //Works fine !
    //It won't give the error. The code will compile successfully.
    //(May cause Segmentation fault when run)
}

main(void) will be called without any parameters. If we try to pass then this end up leading to a compiler error.

Example:

main (void) {
     main(10,"abc",12.13);
     //This throws "error: too many arguments to function ‘main’ "
}

Based on my Comment here is one way to get what you want done:

Start byt selecting any cell in your range and Press Ctrl + T

This will give you this pop up:

make sure the Where is your table text is correct and click ok you will now have:

Now If you add a column header in D it will automatically be added to the table all the way to the last row:

Now If you enter a formula into this column:

After you enter it, the formula will be auto filled all the way to last row:

Now if you add a new row at the next row under your table:

Once entered it will be resized to the width of your table and all columns with formulas will be added also:

Hope this solves your problem!

What @VonC has suggested is nice but I prefer doing all cron job configuration in one line. This would avoid cross platform issues like cronjob location and you don't need a separate cron file.

FROM ubuntu:latest

# Install cron
RUN apt-get -y install cron

# Create the log file to be able to run tail
RUN touch /var/log/cron.log

# Setup cron job
RUN (crontab -l ; echo "* * * * * echo "Hello world" >> /var/log/cron.log") | crontab

# Run the command on container startup
CMD cron && tail -f /var/log/cron.log

After running your docker container, you can make sure if cron service is working by:

# To check if the job is scheduled
docker exec -ti <your-container-id> bash -c "crontab -l"
# To check if the cron service is running
docker exec -ti <your-container-id> bash -c "pgrep cron"

If you prefer to have ENTRYPOINT instead of CMD, then you can substitute the CMD above with

ENTRYPOINT cron start && tail -f /var/log/cron.log

Composition

final class Car {

  private final Engine engine;

  Car(EngineSpecs specs) {
    engine = new Engine(specs);
  }

  void move() {
    engine.work();
  }
}

Aggregation

final class Car {

  private Engine engine;

  void setEngine(Engine engine) {
    this.engine = engine;
  }

  void move() {
    if (engine != null)
      engine.work();
  }
}

In the case of composition, the Engine is completely encapsulated by the Car. There is no way for the outside world to get a reference to the Engine. The Engine lives and dies with the car. With aggregation, the Car also performs its functions through an Engine, but the Engine is not always an internal part of the Car. Engines may be swapped, or even completely removed. Not only that, but the outside world can still have a reference to the Engine, and tinker with it regardless of whether it's in the Car.

Worked a day for this project. It maybe useful for u. I compressed and combined both Network and GPS. Plug and play directly in MainActivity.java (There are some DIY function for display result)

Why don't you examine System.getProperty("os.arch") value in your code?

I'm not sure what you're trying to achieve, but you may want to consider using jQuery, which allows you to put your code in the head tag or a separate script file and still have the code executed after the DOM has loaded.

You can then do something like:

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

as well as selectively removing elements (all DIVs, only DIVs with certain classes, etc.)

java.exe is the command where it waits for application to complete untill it takes the next command. javaw.exe is the command which will not wait for the application to complete. you can go ahead with another commands.

If you have a Google Map inserted by copy/pasting the iframe code and you don't want to use Google Maps API, this is an easy solution. Just execute the following javascript line when you show the hidden map. It just takes the iframe HTML code and insert it in the same place, so it renders again:

document.getElementById("map-wrapper").innerHTML = document.getElementById("map-wrapper").innerHTML;

jQuery version:

$('#map-wrapper').html( $('#map-wrapper').html() );

The HTML:

....
<div id="map-wrapper"><iframe src="https://www.google.com/maps/..." /></div>
....

The following example works for a map initially hidden in a Bootstrap 3 tab:

<script>
$(document).ready( function() {

    /* Detects when the tab is selected */
    $('a[href="#tab-id"]').on('shown.bs.tab', function() {

        /* When the tab is shown the content of the wrapper
           is regenerated and reloaded */

        $('#map-wrapper').html( $('#map-wrapper').html() ); 

    });
});
</script>

Compare date only instead of date + time (NOW) with:

CURDATE()

I know this is a very old post but this may help someone: You can create a method, so whenever you need to pause you can type pause(1000) or any other millisecond value:

public static void pause(int ms) {
    try {
        Thread.sleep(ms);
    } catch (InterruptedException e) {
        System.err.format("IOException: %s%n", e);
    }
}

This is inserted just above the public static void main(String[] args), inside the class. Then, to call on the method, type pause(ms) but replace ms with the number of milliseconds to pause. That way, you don't have to insert the entire try-catch statement whenever you want to pause.

You can use the versatile boost::transform_iterator. The transform_iterator allows you to transform the iterated values, for example in our case when you want to deal only with the keys, not the values. See http://www.boost.org/doc/libs/1_36_0/libs/iterator/doc/transform_iterator.html#example

order by -cast([nativeDateModify] as bigint) desc

To be 32-bit and 64-bit safe, use one of the Boxed Expressions:

  label.text = [NSString stringWithFormat:@"%@", @(count).stringValue];

You have to give elevation prop to View

<View elevation={5} style={styles.container}>
   <Text>Hello World !</Text>
 </View>

styles can be added like this:

 const styles = StyleSheet.create({

     container:{
        padding:20,
        backgroundColor:'#d9d9d9',
        shadowColor: "#000000",
        shadowOpacity: 0.8,
        shadowRadius: 2,
        shadowOffset: {
          height: 1,
          width: 1
        }
       },
   })

Use this line of code when scanning the second value: scanf(" %lf", &b); also replace all %ld with %lf.

It's a problem related with input stream buffer. You can also use fflush(stdin); after the first scanning to clear the input buffer and then the second scanf will work as expected. An alternate way is place a getch(); or getchar(); function after the first scanf line.

I changed scrollable div to be with absolute position, and everything works for me

div.sidebar {
    overflow: hidden;
    background-color: green;
    padding: 5px;
    position: fixed;
    right: 20px;
    width: 40%;
    top: 30px;
    padding: 20px;
    bottom: 30%;
}
div#fixed {
    background: #76a7dc;
    color: #fff;
    height: 30px;
}

div#scrollable {
    overflow-y: scroll;
    background: lightblue;

    position: absolute;
    top:55px; 
    left:20px;
    right:20px;
    bottom:10px;
}

As mentioned in the github issue originally linked by @peter in the comments:

const freshFruits = (fruits as (Apple | Pear)[]).filter((fruit: (Apple | Pear)) => !fruit.isDecayed);

var x = $('#h_v').val();
alert(x);

Maybe you should try removing "new" keyword and see if works. Because last time I got this error when I tried creating Typeface something like this:

Typeface typeface = new Typeface().create("Arial",Typeface.BOLD);

Use the ExecuteStoreQuery method of the entity context. This avoids downloading the entire result set and deserializing into objects to do a simple row count.

   int count;

    using (var db = new MyDatabase()){
      string sql = "SELECT COUNT(*) FROM MyTable where FkId = {0}";

      object[] myParams = {1};
      var cntQuery = db.ExecuteStoreQuery<int>(sql, myParams);

      count = cntQuery.First<int>();
    }

Conditional comment is a comment starts with <!--[if IE]> which couldn't be read by any browser except IE.

from 2011 Conditional comment isn't supported starting form IE 10 as announced by Microsoft in that time https://msdn.microsoft.com/en-us/library/hh801214(v=vs.85).aspx

The only option to use the Conditional comments is to request IE to run your site as IE 9 which supports the Conditional comments.

you can write your own css and/or js files for ie only and other browsers won't load or execute it.

If you want to do something recursively, I suggest you use recursion (yes, you can do it using stacks and so on, but hey).

recursiverm() {
  for d in *; do
    if [ -d "$d" ]; then
      (cd -- "$d" && recursiverm)
    fi
    rm -f *.pdf
    rm -f *.doc
  done
}

(cd /tmp; recursiverm)

That said, find is probably a better choice as has already been suggested.

The Git support done by Microsoft in Visual Studio is just good enough for basic work (commit/fetch/merge and push). My advice is just to avoid it...

I highly prefer GitExtensions (or in less proportion SourceTree). Because seeing the DAG is for me really important to understand how Git works. And you are a lot more aware of what the other contributors to your project have done!

In Visual Studio, you can't quickly see the diff between files or commit, nor (add to the index) and commit only part of modifications. Browse your history is not good either... All that ending in a painful experience!

And, for example, GitExtensions is bundled with interesting plugins: background fetch, GitFlow,... and now, continuous integration!

For the users of Visual Studio 2015, Git is taking shape if you install the GitHub extension. But an external tool is still better ;-)

I encountered this exact issue when I attempted gem install bundler, and I was confused by all the Python responses (since I was using Ruby). Here was my exact error:

ERROR:  Could not find a valid gem 'bundler' (>= 0), here is why:

My solution: I updated Ruby to the most recent version (2.6.5). Problem solved.

You can set height and width like this:

myGraphView.setLayoutParams(new LayoutParams(width, height));

$(function () {

                    e.stopImmediatePropagation();
                    var xhr = new XMLHttpRequest();
                    xhr.open(form.method, form.action);

                            debugger;
                            var responseData = JSON.parse(xhr.responseText);
                            SuccessMethod(responseData); // Redirect to your Success method 
                        }
                    };

In your Action Post Method, pass parameter as HttpPostedFileBase UploadFile and make sure your file input has same as mentioned in your parameter of the Action Method. It should work with AJAX Begin form as well.

Remember over here that your AJAX BEGIN Form will not work over here since you make your post call defined in the code mentioned above and you can reference your method in the code as per the Requirement

I know I am answering late but this is what worked for me

Depending on why you are doing this, using a std::set might be a better idea than std::vector.

It allows each element to occur only once. If you add it multiple times, there will only be one instance to erase anyway. This will make the erase operation trivial. The erase operation will also have lower time complexity than on the vector, however, adding elements is slower on the set so it might not be much of an advantage.

This of course won't work if you are interested in how many times an element has been added to your vector or the order the elements were added.

I don't know if there is a better way, but the following describes how I did it with a counter and background worker thread.

private object _lock = new object();
private int _runningThreads = 0;

private int Counter{
    get{
        lock(_lock)
            return _runningThreads;
    }
    set{
        lock(_lock)
            _runningThreads = value;
    }
}

Now whenever you create a worker thread, increment the counter:

var t = new BackgroundWorker();
// Add RunWorkerCompleted handler

// Start thread
Counter++;

In work completed, decrement the counter:

private void RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    Counter--;
}

Now you can check for the counter anytime to see if any thread is running:

if(Couonter>0){
    // Some thread is yet to finish.
}

Here is a little hack that we ran across while fixing some redraw issues on a large app.

Use -webkit-transform: translateZ(0); on the parent. Of course this is specific to Chrome.

http://jsfiddle.net/senica/bCQEa/

-webkit-transform: translateZ(0);

You could create an animation and apply it to your button view. For example:

    // Locate view
    ImageView diskView = (ImageView) findViewById(R.id.imageView3);

    // Create an animation instance
    Animation an = new RotateAnimation(0.0f, 360.0f, pivotX, pivotY);

    // Set the animation's parameters
    an.setDuration(10000);               // duration in ms
    an.setRepeatCount(0);                // -1 = infinite repeated
    an.setRepeatMode(Animation.REVERSE); // reverses each repeat
    an.setFillAfter(true);               // keep rotation after animation

    // Aply animation to image view
    diskView.setAnimation(an);

Following @VonC great answer. Your GitHub company policy might not allow 'force push' on master.

remote: error: GH003: Sorry, force-pushing to master is not allowed.

If you get an error message like this one please try the following steps.

To effectively reset your fork you need to follow these steps :

git checkout master
git reset --hard upstream/master
git checkout -b tmp_master
git push origin

Open your fork on GitHub, in "Settings -> Branches -> Default branch" choose 'new_master' as the new default branch. Now you can force push on the 'master' branch :

git checkout master
git push --force origin

Then you must set back 'master' as the default branch in the GitHub settings. To delete 'tmp_master' :

git push origin --delete tmp_master
git branch -D tmp_master

Other answers warning about lossing your change still apply, be carreful.

In your action you need first to load companies like so :

$companies = App\Company::all();
return view('listing.company')->with('companies' => $companies)->render();

This will make the companies variable available in the view, and it should render the HTML correctly.

Try to use postman chrome extension to debug your view.

Edit Web Config for each crystaldecisions file version make it equal the same version off the dll file (from rght click on it and select from properties from solution explorer ) Eg. crystaldecisions.reportappserver.commlayer.dll --> 13.0.2000.0 after upgrade crystal report to CRforVS_13_0_21 edit it to ---> 13.0.35.00.0

How about Freebase? I think they have an API available, too.

I use my custom ng-repeat-range directive:

/**
 * Ng-Repeat implementation working with number ranges.
 *
 * @author Umed Khudoiberdiev
 */
angular.module('commonsMain').directive('ngRepeatRange', ['$compile', function ($compile) {
    return {
        replace: true,
        scope: { from: '=', to: '=', step: '=' },

        link: function (scope, element, attrs) {

            // returns an array with the range of numbers
            // you can use _.range instead if you use underscore
            function range(from, to, step) {
                var array = [];
                while (from + step <= to)
                    array[array.length] = from += step;

                return array;
            }

            // prepare range options
            var from = scope.from || 0;
            var step = scope.step || 1;
            var to   = scope.to || attrs.ngRepeatRange;

            // get range of numbers, convert to the string and add ng-repeat
            var rangeString = range(from, to + 1, step).join(',');
            angular.element(element).attr('ng-repeat', 'n in [' + rangeString + ']');
            angular.element(element).removeAttr('ng-repeat-range');

            $compile(element)(scope);
        }
    };
}]);

and html code is

<div ng-repeat-range from="0" to="20" step="5">
    Hello 4 times!
</div>

or simply

<div ng-repeat-range from="5" to="10">
    Hello 5 times!
</div>

or even simply

<div ng-repeat-range to="3">
    Hello 3 times!
</div>

or just

<div ng-repeat-range="7">
    Hello 7 times!
</div>

You can use RelativeSource to find the parent element, like this -

Whenever you have a module followed by a variable on the same line in ansible the parser will treat the reference variable as the beginning of an in-line dictionary. For example:

- name: some example
  command: {{ myapp }} -a foo

The default here is to parse the first part of {{ myapp }} -a foo as a dictionary instead of a string and you will get an error.

So you must quote the argument like so:

- name: some example
  command: "{{ myapp }} -a foo"

If you can modify your stored data, use a sentinel value for missing id. A common use case, inferred by the column name, being that id is an integer, strictly greater than zero, you could use 0 as a sentinel value so that you can write

if row['id']:
   regular_process(row)
else:
   special_process(row)

When you perform a boolean comparison between two vectors in R, the "expectation" is that both vectors are of the same length, so that R can compare each corresponding element in turn.

R has a much loved (or hated) feature called recycling, whereby in many circumstances if you try to do something where R would normally expect objects to be of the same length, it will automatically extend, or recycle, the shorter object to force both objects to be of the same length.

If the longer object is a multiple of the shorter, this amounts to simply repeating the shorter object several times. Oftentimes R programmers will take advantage of this to do things more compactly and with less typing.

But if they are not multiples, R will worry that you may have made a mistake, and perhaps didn't mean to perform that comparison, hence the warning.

Explore yourself with the following code:

> x <- 1:3
> y <- c(1,2,4)
> x == y
[1]  TRUE  TRUE FALSE
> y1 <- c(y,y)
> x == y1
[1]  TRUE  TRUE FALSE  TRUE  TRUE FALSE
> y2 <- c(y,2)
> x == y2
[1]  TRUE  TRUE FALSE FALSE
Warning message:
In x == y2 :
  longer object length is not a multiple of shorter object length

This happened to me, and it was caused the absence of a comment (should say "comment required" instead of this enigmatic error at first, right...)

I'm working on a Mac, OSX 10.9. I recently had to update my JDK to 1.7 for some VPN software. The application I'm working runs on JDK 1.6, so a GlassFish had to run with JDK 1.6. It took a minute to iron this out, but here's how it went for me. I work with the NetBeans IDE by the way.

1. My GlssFish configuration file

   /Applications/NetBeans/glassfish-3.1.2.2/glassfish/config/asenv.conf

2. Path to JDK 1.6

   /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home

3. I added the following line to the bottom of my asenv.conf file

   AS_JAVA=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home

as a sidenote, replace doesn't have to move all zeros. If you just want to remove the first specify count to 1:

'asd0asd0'.replace('0','',1)

Out:

'asdasd0'

I found this helpful

$('select[name=users] option:selected').text()

When accessing the selector using the this keyword.

$(this).find('option:selected').text()

A quick true/false test of whether it will cast to [int]

[bool]($var -as [int] -is [int])

From JDK 14+ which includes JEP 305 we can do Pattern Matching for instanceof

Patterns basically test that a value has a certain type, and can extract information from the value when it has the matching type.

Before Java 14

if (obj instanceof String) {
    String str = (String) obj; // need to declare and cast again the object
    .. str.contains(..) ..
}else{
     str = ....
}

Java 14 enhancements

if (!(obj instanceof String str)) {
    .. str.contains(..) .. // no need to declare str object again with casting
} else {
    .. str....
}

We can also combine the type check and other conditions together

if (obj instanceof String str && str.length() > 4) {.. str.contains(..) ..}

The use of pattern matching in instanceof should reduce the overall number of explicit casts in Java programs.

PS: instanceOf will only match when the object is not null, then only it can be assigned to str.

Try with this

->groupBy('state_id','locality')
  ->havingRaw('count > 1 ')
  ->having('items.name','LIKE',"%$keyword%")
  ->orHavingRaw('brand LIKE ?',array("%$keyword%"))

It's easier to use only one code block, then you only need one redirection.

I couldn't get GetAccessControl() to throw an exception on Windows 7 as recommended in the accepted answer.

I ended up using a variation of sdds's answer:

        try
        {
            bool writeable = false;
            WindowsPrincipal principal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
            DirectorySecurity security = Directory.GetAccessControl(pstrPath);
            AuthorizationRuleCollection authRules = security.GetAccessRules(true, true, typeof(SecurityIdentifier));

            foreach (FileSystemAccessRule accessRule in authRules)
            {

                if (principal.IsInRole(accessRule.IdentityReference as SecurityIdentifier))
                {
                    if ((FileSystemRights.WriteData & accessRule.FileSystemRights) == FileSystemRights.WriteData)
                    {
                        if (accessRule.AccessControlType == AccessControlType.Allow)
                        {
                            writeable = true;
                        }
                        else if (accessRule.AccessControlType == AccessControlType.Deny)
                        {
                            //Deny usually overrides any Allow
                            return false;
                        }

                    } 
                }
            }
            return writeable;
        }
        catch (UnauthorizedAccessException)
        {
            return false;
        }

Hope this helps.

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

There's a tiny open-source component to sync/communicate between tabs/windows of the same origin (disclaimer - I'm one of the contributors!) based around localStorage.

TabUtils.BroadcastMessageToAllTabs("eventName", eventDataString);

    DoSomething();
});

TabUtils.CallOnce("lockname", function () {
    alert("I run only once across multiple tabs");
});

P.S. I took the liberty to recommend it here since most of the "lock/mutex/sync" components fail on websocket connections when events happen almost simultaneously

Using input() implies Python 3, recent Python 3 versions have made the IOError exception deprecated (it is now an alias for OSError). So assuming you are using Python 3.3 or later:

fn = input('Enter file name: ')
try:
    file = open(fn, 'r')
except FileNotFoundError:
    file = open(fn, 'w')

1. Go to .gitignore file and add the entry for the files you want to ignore
2. Run git rm -r --cached .
3. Now run git add .

Given an environment where you have multiple developers accessing the same repository the following guidelines may help.

Ensure that you have a unix group that all devs belong to and give ownership of the .git repository to that group.

1. In the .git/config of the server repository set sharedrepository = true. (This tells git to allow multiple users which is needed for commits and deployment.

2. set the umask of each user in their bashrc files to be the same - 002 is a good start

To fully comply with RSpec ~> 3.1 syntax and rubocop-rspec's default option for rule RSpec/MessageSpies, here's what you can do with spy:

Message expectations put an example's expectation at the start, before you've invoked the code-under-test. Many developers prefer using an arrange-act-assert (or given-when-then) pattern for structuring tests. Spies are an alternate type of test double that support this pattern by allowing you to expect that a message has been received after the fact, using have_received.

# arrange.
invitation = spy('invitation')

# act.
invitation.deliver("[email protected]")

# assert.
expect(invitation).to have_received(:deliver).with("[email protected]")

If you don't use rubocop-rspec or using non-default option. You may, of course, use RSpec 3 default with expect.

dbl = double("Some Collaborator")
expect(dbl).to receive(:foo).with("[email protected]")

Try:

    if (textBox1.Text == "" || textBox2.Text == "")
    {
        // do something..
    }

Instead of:

    if (textBox1.Text == string.Empty || textBox2.Text == string.Empty)
    {
        // do something..
    }

Because string.Empty is different than - "".

        System.out.println(line);
    }

} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

I find myself in the same situation with the difference than in my case the element was a flex container.If is not your case an easy work around could be

[style.display]="!isLoading ? 'block' : 'none'"

in my case due to the fact that a lot of browsers that we support still need the vendor prefix to avoid problems i went for another easy solution

[class.is-loading]="isLoading"

where then the CSS is simple as

&.is-loading { display: none } 

to leave then the displayed state handled by the default class.

If you need the construct for a quick example to play with, use the : operator.

But if you are creating a vector/range of numbers dynamically, then use seq() instead.

Let's say you are creating the vector/range of numbers from a to b with a:b, and you expect it to be an increasing series. Then, if b is evaluated to be less than a, you will get a decreasing sequence but you will never be notified about it, and your program will continue to execute with the wrong kind of input.

In this case, if you use seq(), you can set the sign of the by argument to match the direction of your sequence, and an error will be raised if they do not match. For example,

seq(a, b, -1)

will raise an error for a=2, b=6, because the coder expected a decreasing sequence.

Rails has an except/except! method that returns the hash with those keys removed. If you're already using Rails, there's no sense in creating your own version of this.

class Hash
  # Returns a hash that includes everything but the given keys.
  #   hash = { a: true, b: false, c: nil}
  #   hash.except(:c) # => { a: true, b: false}
  #   hash # => { a: true, b: false, c: nil}
  #
  # This is useful for limiting a set of parameters to everything but a few known toggles:
  #   @person.update(params[:person].except(:admin))
  def except(*keys)
    dup.except!(*keys)
  end

  # Replaces the hash without the given keys.
  #   hash = { a: true, b: false, c: nil}
  #   hash.except!(:c) # => { a: true, b: false}
  #   hash # => { a: true, b: false }
  def except!(*keys)
    keys.each { |key| delete(key) }
    self
  end
end

I solved the same problem of having to reset a form at its pristine state in Angular version 1.0.7 (no $setPristine method)

In my use case, the form, after being filled and submitted must disappear until it is again necessary for filling another record. So I made the show/hide effect by using ng-switch instead of ng-show. As I suspected, with ng-switch, the form DOM sub-tree is completely removed and later recreated. So the pristine state is automatically restored.

I like it because it is simple and clean but it may not be a fit for anybody's use case.

it may also imply some performance issues for big forms (?) In my situation I did not face this problem yet.

Everyone explained the topic very well. There is one more point i would like add about .load() method.

As per Load document if you add suffixed selector in data url then it will not execute scripts in loading content.

Working Plunker

            $(document).ready(function(){
                $("#secondPage").load("mySecondHtmlPage.html #content");
            })

On the other hand, after removing selector in url, scripts in new content will run. Try this example

after removing #content in url in index.html file

            $(document).ready(function(){
                $("#secondPage").load("mySecondHtmlPage.html");
            })

There is no such in-built feature provided by other methods in discussion.

Another python3 implementation that involves the use of Abstract classes with super(). You should remember that

super().__init__(name, 10)

has the same effect as

Person.__init__(self, name, 10)

Remember there's a hidden 'self' in super(), So the same object passes on to the superclass init method and the attributes are added to the object that called it. Hence super()gets translated to Person and then if you include the hidden self, you get the above code frag.

from abc import ABCMeta, abstractmethod
class Person(metaclass=ABCMeta):
    name = ""
    age = 0

    def __init__(self, personName, personAge):
        self.name = personName
        self.age = personAge

    @abstractmethod
    def showName(self):
        pass

    @abstractmethod
    def showAge(self):
        pass


class Man(Person):

    def __init__(self, name, height):
        self.height = height
        # Person.__init__(self, name, 10)
        super().__init__(name, 10)  # same as Person.__init__(self, name, 10)
        # basically used to call the superclass init . This is used incase you want to call subclass init
        # and then also call superclass's init.
        # Since there's a hidden self in the super's parameters, when it's is called,
        # the superclasses attributes are a part of the same object that was sent out in the super() method

    def showIdentity(self):
        return self.name, self.age, self.height

    def showName(self):
        pass

    def showAge(self):
        pass


a = Man("piyush", "179")
print(a.showIdentity())

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

A public item is one that is accessible from any other class. You just have to know what object it is and you can use a dot operator to access it. Protected means that a class and its subclasses have access to the variable, but not any other classes, they need to use a getter/setter to do anything with the variable. A private means that only that class has direct access to the variable, everything else needs a method/function to access or change that data. Hope this helps.

Note: The first() method doesn't throw an exception as described in the original question. If you're getting this kind of exception, there is another error in your code.

The correct way to user first() and check for a result:

$user = User::where('mobile', Input::get('mobile'))->first(); // model or null
if (!$user) {
   // Do stuff if it doesn't exist.
}

Other techniques (not recommended, unnecessary overhead):

$user = User::where('mobile', Input::get('mobile'))->get();

if (!$user->isEmpty()){
    $firstUser = $user->first()
}

or

try {
    $user = User::where('mobile', Input::get('mobile'))->firstOrFail();
    // Do stuff when user exists.
} catch (ErrorException $e) {
    // Do stuff if it doesn't exist.
}

or

// Use either one of the below. 
$users = User::where('mobile', Input::get('mobile'))->get(); //Collection

if (count($users)){
    // Use the collection, to get the first item use $users->first().
    // Use the model if you used ->first();
}

Each one is a different way to get your required result.

In order to be able to copy and paste results from SQL Server Management Studio 2012 to Excel or to export to Csv with list separators you must first change the query option.

1. Click on Query then options.

2. Under Results click on the Grid.

3. Check the box next to:

   Quote strings containing list separators when saving .csv results.

This should solve the problem.

You cannot use the datetime function using the Java wrapper "ContentValues". Either you can use :

• SQLiteDatabase.execSQL so you can enter a raw SQL query.

  mDb.execSQL("INSERT INTO "+DATABASE_TABLE+" VALUES (null, datetime()) ");
  

• Or the java date time capabilities :

  // set the format to sql date time
  SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
  Date date = new Date();
  ContentValues initialValues = new ContentValues(); 
  initialValues.put("date_created", dateFormat.format(date));
  long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
  

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

For setting the Socket timeout, you need to follow these steps:

import socket
socks = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socks.settimeout(10.0) # settimeout is the attr of socks.

You can use duplicated to do this very quickly.

test[!duplicated(test$id),]

Benchmarks, for the speed freaks:

ju <- function() test[!duplicated(test$id),]
gs1 <- function() do.call(rbind, lapply(split(test, test$id), head, 1))
gs2 <- function() do.call(rbind, lapply(split(test, test$id), `[`, 1, ))
jply <- function() ddply(test,.(id),function(x) head(x,1))
jdt <- function() {
  testd <- as.data.table(test)
  setkey(testd,id)
  # Initial solution (slow)
  # testd[,lapply(.SD,function(x) head(x,1)),by = key(testd)]
  # Faster options :
  testd[!duplicated(id)]               # (1)
  # testd[, .SD[1L], by=key(testd)]    # (2)
  # testd[J(unique(id)),mult="first"]  # (3)
  # testd[ testd[,.I[1L],by=id] ]      # (4) needs v1.8.3. Allows 2nd, 3rd etc
}

library(plyr)
library(data.table)
library(rbenchmark)

# sample data
set.seed(21)
test <- data.frame(id=sample(1e3, 1e5, TRUE), string=sample(LETTERS, 1e5, TRUE))
test <- test[order(test$id), ]

benchmark(ju(), gs1(), gs2(), jply(), jdt(),
    replications=5, order="relative")[,1:6]
#     test replications elapsed relative user.self sys.self
# 1   ju()            5    0.03    1.000      0.03     0.00
# 5  jdt()            5    0.03    1.000      0.03     0.00

# 4 jply()            5    3.69  123.000      3.11     0.51

Let's try that again, but with just the contenders from the first heat and with more data and more replications.

set.seed(21)
test <- data.frame(id=sample(1e4, 1e6, TRUE), string=sample(LETTERS, 1e6, TRUE))
test <- test[order(test$id), ]
benchmark(ju(), jdt(), order="relative")[,1:6]
#    test replications elapsed relative user.self sys.self
# 1  ju()          100    5.48    1.000      4.44     1.00
# 2 jdt()          100    6.92    1.263      5.70     1.15

Please make sure that your home partition is mounted with executable permissions. That is the default, but if you happen to mount it without exec option, you will get this error.

it is always good to restrict the DOM search. so better to use a parent also, so that the entire DOM won't be traversed.

In a nutshell :

-> Git Merge: It will simply merge your local changes and remote changes, and that will create another commit history record

-> Git Rebase: It will put your changes above all new remote changes, and rewrite commit history, so your commit history will be much cleaner than git merge. Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

If you want to automate the creating of a custom divergent colormap commonly used for surface plots, this module combined with @unutbu method worked well for me.

def diverge_map(high=(0.565, 0.392, 0.173), low=(0.094, 0.310, 0.635)):
    '''
    low and high are colors that will be used for the two
    ends of the spectrum. they can be either color strings
    or rgb color tuples
    '''
    c = mcolors.ColorConverter().to_rgb
    if isinstance(low, basestring): low = c(low)
    if isinstance(high, basestring): high = c(high)
    return make_colormap([low, c('white'), 0.5, c('white'), high])

The high and low values can be either string color names or rgb tuples. This is the result using the surface plot demo:

Just set the opacity for the inner table. You can do inline CSS if you want it just for a specific table element, so it doesn't apply to the entire table.

style="opacity: 0%;"

You can use the function numpy.nonzero(), or the nonzero() method of an array

import numpy as np

A = np.array([[2,4],
          [6,2]])
index= np.nonzero(A>1)
       OR
(A>1).nonzero()

Output:

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

First array in output depicts the row index and second array depicts the corresponding column index.

I'm an async novice, so I can't tell you definitively what is happening here. I suspect that there's a mismatch in the method execution expectations, even though you are using tasks internally in the methods. I think you'd get the results you are expecting if you changed Print to return a Task<string>:

private static string Send(int id)
{
    Task<HttpResponseMessage> responseTask = client.GetAsync("aaaaa");
    Task<string> result;
    responseTask.ContinueWith(x => result = Print(x));
    result.Wait();
    responseTask.Wait(); // There's likely a better way to wait for both tasks without doing it in this awkward, consecutive way.
    return result.Result;
}

private static Task<string> Print(Task<HttpResponseMessage> httpTask)
{
    Task<string> task = httpTask.Result.Content.ReadAsStringAsync();
    string result = string.Empty;
    task.ContinueWith(t =>
    {
        Console.WriteLine("Result: " + t.Result);
        result = t.Result;
    });
    return task;
}

{ $where: "this.pictures.length > 1" }

use the $where and pass the this.field_name.length which return the size of array field and check it by comparing with number. if any array have any value than array size must be at least 1. so all the array field have length more than one, it means it have some data in that array

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

Hey, this one is kind of ugly but it's one line only:

I don't have enough reputation to comment, but in case somebody is looking for an extrapolation wrapper for a linear 2d-interpolation with scipy, I have adapted the answer that was given here for the 1d interpolation.

def extrap2d(interpolator):
xs = interpolator.x
ys = interpolator.y
zs = interpolator.z
zs = np.reshape(zs, (-1, len(xs)))
def pointwise(x, y):
    if x < xs[0] or y < ys[0]:
        x1_index = np.argmin(np.abs(xs - x))
        x2_index = x1_index + 1
        y1_index = np.argmin(np.abs(ys - y))
        y2_index = y1_index + 1
        x1 = xs[x1_index]
        x2 = xs[x2_index]
        y1 = ys[y1_index]
        y2 = ys[y2_index]
        z11 = zs[x1_index, y1_index]
        z12 = zs[x1_index, y2_index]
        z21 = zs[x2_index, y1_index]
        z22 = zs[x2_index, y2_index]

        return (z11 * (x2 - x) * (y2 - y) +

    else:

I haven't commented a lot and I am aware, that the code isn't super clean. If anybody sees any errors, please let me know. In my current use-case it is working without a problem :)

What about pymysql? It's pure Python, and I've used it on Windows with considerable success, bypassing the difficulties of compiling and installing mysql-python.

I solved this problem by this solution.

1) The function returns a cell for a table view yes? So, the returned object is of type UITableViewCell. These are the objects that you see in the table's rows. This function basically returns a cell, for a table view. But you might ask, how the function would know what cell to return for what row, which is answered in the 2nd question

2)NSIndexPath is essentially two things-

• Your Section
• Your row

Because your table might be divided to many sections and each with its own rows, this NSIndexPath will help you identify precisely which section and which row. They are both integers. If you're a beginner, I would say try with just one section.

It is called if you implement the UITableViewDataSource protocol in your view controller. A simpler way would be to add a UITableViewController class. I strongly recommend this because it Apple has some code written for you to easily implement the functions that can describe a table. Anyway, if you choose to implement this protocol yourself, you need to create a UITableViewCell object and return it for whatever row. Have a look at its class reference to understand re-usablity because the cells that are displayed in the table view are reused again and again(this is a very efficient design btw).

As for when you have two table views, look at the method. The table view is passed to it, so you should not have a problem with respect to that.

Without any example data, it really is difficult to know exactly what you are wanting. For instance, I can't at all divine what your object set (or is it sets) looks like.

That said, does the following help at all?

set1 <- data.frame(x = 4:6, y = 6:4, z = c(1, 3, 5))

plot(1:10, type="n")
XX <- "set1"
with(eval(as.symbol(XX)), symbols(x, y, circles = z, add=TRUE))

EDIT:

Now that I see your real task, here is a one-liner that'll do everything you want without requiring any for() loops:

with(dat, symbols(sq, cu, circles = num,
                  bg = c("red", "blue")[(num>5) + 1]))

The one bit of code that may feel odd is the bit specifying the background color. Try out these two lines to see how it works:

c(TRUE, FALSE) + 1
# [1] 2 1
c("red", "blue")[c(F, F, T, T) + 1]
# [1] "red"  "red"  "blue" "blue"

create resource layout file list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="wrap_content">
<TextView
        android:id="@+id/header_text"
        android:layout_height="0dp"
        android:layout_width="fill_parent"
        android:layout_weight="1"
        android:text="Header"
        />
<TextView
        android:id="@+id/item_text"
        android:layout_height="0dp"

        android:layout_weight="1"
        android:text="dynamic text"
        />
</LinearLayout>

and initialise adaptor like this

adapter = new ArrayAdapter<String>(this, R.layout.list_item,R.id.item_text,data_array);

Suppose: SqlConnection connectionObj = new SqlConnection()

for : connectionObj.ConnectionString -> use server name : (localdb)\\MSSQLLocalDB.

let objViewController = self.storyboard?.instantiateViewController(withIdentifier: "ViewController") as! ViewController

You might need to do some checking. You cannot safely convert factors directly to numeric. as.character must be applied first. Otherwise, the factors will be converted to their numeric storage values. I would check each column with is.factor then coerce to numeric as necessary.

df1[] <- lapply(df1, function(x) {
    if(is.factor(x)) as.numeric(as.character(x)) else x
})
sapply(df1, class)
#         a         b 
# "numeric" "numeric" 

Ideally, every custom watch should be removed when you leave the scope.

It helps in better memory management and better app performance.

// call to $watch will return a de-register function
var listener = $scope.$watch(someVariableToWatch, function(....));

$scope.$on('$destroy', function() {
    listener(); // call the de-register function on scope destroy
});

It seems you could simply go with

awk '{print $1 " " $2}' file

This prints the two first fields of each line in your input file, separated with a space.

I agree on performing the replace on the SQL side, but using the ISNULL function would be the way I'd go.

SELECT ISNULL(table.MyField, "NA") AS MyField

I usually do as much processing of data on our SQL servers and try to do as little data manipulation in SSRS as possible. This is mainly because my SQL server is considerably more powerful than my SSRS server.

Now here's a twist:

You should place all fonts in app/assets/fonts/ as they WILL get precompiled in staging and production by default—they will get precompiled when pushed to heroku.

Font files placed in vendor/assets will NOT be precompiled on staging or production by default — they will fail on heroku. Source!

— @plapier, thoughtbot/bourbon

I strongly believe that putting vendor fonts into vendor/assets/fonts makes a lot more sense than putting them into app/assets/fonts. With these 2 lines of extra configuration this has worked well for me (on Rails 4):

app.config.assets.paths << Rails.root.join('vendor', 'assets', 'fonts')  
app.config.assets.precompile << /\.(?:svg|eot|woff|ttf)$/

— @jhilden, thoughtbot/bourbon

I've also tested it on rails 4.0.0. Actually the last one line is enough to safely precompile fonts from vendor folder. Took a couple of hours to figure it out. Hope it helped someone.

var data = {"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"}

var parsedData = JSON.parse(data);
alert(parsedData.name);
alert(parsedData.skills);
alert(parsedData.jobtitel);
alert(parsedData.res_linkedin);

After a lot of research, I finally figured this one out.

DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) { // Change `2.0` to the desired number of seconds.
   // Code you want to be delayed
}

This creates the desired "wait" effect in Swift 3 and Swift 4.

Inspired by a part of this answer.

for more exactly positioning:

      background-position: bottom 5px right 7px;

I got this issue when I used an ajax call to retrieve data from the database. When the controller returned the array it converted it to a boolean. The problem was that I had "invalid characters" like ú (u with accent).

StackBlitz

Template: You can either use the native change event or NgModel directive's ngModelChange.

<input type="checkbox" (change)="onNativeChange($event)"/>

or

<input type="checkbox" ngModel (ngModelChange)="onNgModelChange($event)"/>

TS:

onNativeChange(e) { // here e is a native event
  if(e.target.checked){
    // do something here
  }
}

onNgModelChange(e) { // here e is a boolean, true if checked, otherwise false
  if(e){
    // do something here
  }
}

if
  ...
  # several checks
  ...
elif ((var1 > 65535) or ((var1 < 1024)) and (var1 != 80) and (var1 != 443)):
  # fail
else
  ...

You missed a parenthesis.

I think the problem is with the way you designed your data. To me in terms of semantics, it just doesn't make sense. What exactly is steps for?

Does it store the information of one company?

If that's the case steps should be an object (see KayakDave's answer) and each "step" should be an object property.

Does it store the information of multiple companies?

If that's the case, steps should be an array of objects.

$scope.steps=[{companyName: true, businessType: true},{companyName: false}]

In either case you can easily iterate through the data with one (two for 2nd case) ng-repeats.

This worked for me

Python is a dynamic, strongly typed, object oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax.

1. Python is dynamically typed: it means that you don't declare a type (e.g. 'integer') for a variable name, and then assign something of that type (and only that type). Instead, you have variable names, and you bind them to entities whose type stays with the entity itself. a = 5 makes the variable name a to refer to the integer 5. Later, a = "hello" makes the variable name a to refer to a string containing "hello". Static typed languages would have you declare int a and then a = 5, but assigning a = "hello" would have been a compile time error. On one hand, this makes everything more unpredictable (you don't know what a refers to). On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult.
2. Python is strongly typed. It means that if a = "5" (the string whose value is '5') will remain a string, and never coerced to a number if the context requires so. Every type conversion in python must be done explicitly. This is different from, for example, Perl or Javascript, where you have weak typing, and can write things like "hello" + 5 to get "hello5".
3. Python is object oriented, with class-based inheritance. Everything is an object (including classes, functions, modules, etc), in the sense that they can be passed around as arguments, have methods and attributes, and so on.
4. Python is multipurpose: it is not specialised to a specific target of users (like R for statistics, or PHP for web programming). It is extended through modules and libraries, that hook very easily into the C programming language.
5. Python enforces correct indentation of the code by making the indentation part of the syntax. There are no control braces in Python. Blocks of code are identified by the level of indentation. Although a big turn off for many programmers not used to this, it is precious as it gives a very uniform style and results in code that is visually pleasant to read.
6. The code is compiled into byte code and then executed in a virtual machine. This means that precompiled code is portable between platforms.

Python can be used for any programming task, from GUI programming to web programming with everything else in between. It's quite efficient, as much of its activity is done at the C level. Python is just a layer on top of C. There are libraries for everything you can think of: game programming and openGL, GUI interfaces, web frameworks, semantic web, scientific computing...

I prefer inline-block, but float are still useful way to put together HTML elemenets, specially when we have elements which one should stick to the left and one to the right, float working better with writing less lines, while inline-block working well in many other cases.

For the real problem about being unable to properly debug a program that uses JNI (or the bug does not appear when running it under a debugger):

In this case it often helps to add Java wrappers around your JNI calls (i.e. all native methods are private and your public methods in the class call them) that do some basic sanity checking (check that all "objects" are freed and "objects" are not used after freeing) or synchronization (just synchronize all methods from one DLL to a single object instance). Let the java wrapper methods log the mistake and throw an exception.

This will often help to find the real error (which surprisingly is mostly in the Java code that does not obey the semantics of the called functions causing some nasty double-frees or similar) more easily than trying to debug a massively parallel Java program in a native debugger...

If you know the cause, keep the code in your wrapper methods that avoids it. Better have your wrapper methods throw exceptions than your JNI code crash the VM...

graphics.h appears to something once bundled with Borland and/or Turbo C++, in the 90's.

http://www.daniweb.com/software-development/cpp/threads/17709/88149#post88149

It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

You can see the difference with the following example:

<a href="http://www.google.co.uk/" onclick="return (confirm('Follow this link?'))">Google</a>

Clicking "Okay" returns true, and the link is followed. Clicking "Cancel" returns false and doesn't follow the link. If javascript is disabled the link is followed normally.

I think if you have something that structured and complex, you might consider something other than a single drop-down box.

lock(...) works, but may block a thread, and could cause deadlock if other code is using the same locks in an incompatible way.

Interlocked.* is the correct way to do it ... much less overhead as modern CPUs support this as a primitive.

volatile on its own is not correct. A thread attempting to retrieve and then write back a modified value could still conflict with another thread doing the same.

Slightly abbreviated could be...

echo date("Y-m-d H:i:s", strtotime($mysqltime));

Found in one of the Chrome sample applications, although this is meant for larger blocks of data where you're okay with an asynchronous conversion.

/**
 * Converts an array buffer to a string
 *
 * @private
 * @param {ArrayBuffer} buf The buffer to convert
 * @param {Function} callback The function to call when conversion is complete
 */
function _arrayBufferToString(buf, callback) {
  var bb = new Blob([new Uint8Array(buf)]);
  var f = new FileReader();
  f.onload = function(e) {
    callback(e.target.result);
  };
  f.readAsText(bb);
}

Or if all borders have same style, just:

border:10px;

The primary flag seems to only work for vagrant ssh for me.

In the past I have used the following method to hack around the issue.

# stage box intended for configuration closely matching production if ARGV[1] == 'stage'     config.vm.define "stage" do |stage|         box_setup stage, \         "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml"     end end 

$(window).unbind('scroll');

Even though the documentation says it will remove all event handlers if called with no arguments, it is worth giving a try explicitly unbinding it.

Update

It worked if you used single quotes? That doesn't sound right - as far as I know, JavaScript treats single and double quotes the same (unlike some other languages like PHP and C).

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

Packages and stored procedures in Oracle execute by default using the rights of the package/procedure OWNER, not the currently logged on user.

So if you call a package that creates a user for example, its the package owner, not the calling user that needs create user privilege. The caller just needs to have execute permission on the package.

If you would prefer that the package should be run using the calling user's permissions, then when creating the package you need to specify AUTHID CURRENT_USER

Oracle documentation "Invoker Rights vs Definer Rights" has more information http://docs.oracle.com/cd/A97630_01/appdev.920/a96624/08_subs.htm#18575

}

this should do the job

applyFilters(users, filter);

this inside the step callback isn't the element but the object passed to animate()

$('.Count').each(function (_, self) {

Another way to do this and keep the references to this would be

$('.Count').each(function () {
    $(this).prop('Counter',0).animate({
        Counter: $(this).text()
    }, {
        duration: 1000,

        }
    });
});

Use .textContent instead.

I was struggling with changing the value of a label as well, until I tried this.

If this doesn't solve try inspecting the object to see what properties you can set by logging it to the console with console.dir as shown on this question: How can I log an HTML element as a JavaScript object?

Yes, you will have no problems using:

if (BuildConfig.DEBUG) {
   //It's not a release version.
}

Unless you are importing the wrong BuildConfig class. Make sure you are referencing your project's BuildConfig class, not from any of your dependency libraries.

This post is a little bit old, but here is another easy solution for getting data related to Call logs content provider in Android:

Use this lib: https://github.com/EverythingMe/easy-content-providers

Get all calls:

CallsProvider callsProvider = new CallsProvider(context);
List<Call> calls = callsProvider.getCalls().getList();

Each Call has all fields, so you can get any info you need:
callDate, duration, number, type(INCOMING, OUTGOING, MISSED), isRead, ...

It works with List or Cursor and there is a sample app to see how it looks and works.

In fact, there is a support for all Android content providers like: Contacts, SMS, Calendar, ... Full doc with all options: https://github.com/EverythingMe/easy-content-providers/wiki/Android-providers

Hope it also helped :)

If you install using bundler as suggested by gryzzly and the gem creates a binary then make sure you run it with bundle exec mygembinary as the gem is stored in a bundler directory which is not visible on the normal gem path.

CodeIgniter User Guide says:

$this->uri->segment(n)

Permits you to retrieve a specific segment. Where n is the segment number you wish to retrieve. Segments are numbered from left to right. For example, if your full URL is this: http://example.com/index.php/news/local/metro/crime_is_up

The segment numbers would be this:

1. news
2. local
3. metro
4. crime_is_up

So segment refers to your url structure segment. By the above example, $this->uri->segment(3) would be 'metro', while $this->uri->segment(4) would be 'crime_is_up'.

These lines in your makefile,

INC_DIR = ../StdCUtil
CFLAGS=-c -Wall -I$(INC_DIR)
DEPS = split.h

and this line in your .cpp file,

#include "StdCUtil/split.h"

are in conflict.

With your makefile in your source directory and with that -I option you should be using #include "split.h" in your source file, and your dependency should be ../StdCUtil/split.h.

Another option:

INC_DIR = ../StdCUtil
CFLAGS=-c -Wall -I$(INC_DIR)/..  # Ugly!
DEPS = $(INC_DIR)/split.h

With this your #include directive would remain as #include "StdCUtil/split.h".

Yet another option is to place your makefile in the parent directory:

root
  |____Makefile
  |
  |___Core
  |     |____DBC.cpp
  |     |____Lock.cpp
  |     |____Trace.cpp
  |
  |___StdCUtil
        |___split.h

With this layout it is common to put the object files (and possibly the executable) in a subdirectory that is parallel to your Core and StdCUtil directories. Object, for example. With this, your makefile becomes:

INC_DIR = StdCUtil
SRC_DIR = Core
OBJ_DIR = Object
CFLAGS  = -c -Wall -I.
SRCS = $(SRC_DIR)/Lock.cpp $(SRC_DIR)/DBC.cpp $(SRC_DIR)/Trace.cpp
OBJS = $(OBJ_DIR)/Lock.o $(OBJ_DIR)/DBC.o $(OBJ_DIR)/Trace.o
# Note: The above will soon get unwieldy.
# The wildcard and patsubt commands will come to your rescue.

DEPS = $(INC_DIR)/split.h
# Note: The above will soon get unwieldy.
# You will soon want to use an automatic dependency generator.


all: $(OBJS)

$(OBJ_DIR)/%.o: $(SRC_DIR)/%.cpp
  $(CC) $(CFLAGS) -c $< -o $@

$(OBJ_DIR)/Trace.o: $(DEPS)

For Linux to reset current 30 days expiration license, you must run code:

rm ~/.config/JetBrains/IntelliJIdea2019.3/options/other.xml
rm -rf ~/.config/JetBrains/IntelliJIdea2019.3/eval/*
rm -rf .java/.userPrefs

You can do this by using the following xml

<RelativeLayout
    style="@style/GenericProgressBackground"
    android:id="@+id/loadingPanel"
    >
    <ProgressBar
        style="@style/GenericProgressIndicator"/>
</RelativeLayout>

With this style

<style name="GenericProgressBackground" parent="android:Theme">
    <item name="android:layout_width">fill_parent</item>    
    <item name="android:layout_height">fill_parent</item>
    <item name="android:background">#DD111111</item>    
    <item name="android:gravity">center</item>  
</style>
<style name="GenericProgressIndicator" parent="@android:style/Widget.ProgressBar.Small">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:indeterminate">true</item> 
</style>

To use this, you must hide your UI elements by setting the visibility value to GONE and whenever the data is loaded, call setVisibility(View.VISIBLE) on all your views to restore them. Don't forget to call findViewById(R.id.loadingPanel).setVisiblity(View.GONE) to hide the loading animation.

If you dont have a loading event/function but just want the loading panel to disappear after x seconds use a Handle to trigger the hiding/showing.

Android SDK Build Tools are exactly what the name says they are; tools for building Android Applications.It is very important to use the latest build tools version (selected automatically by your IDE via the Android SDK) but the reason the old versions are left there is to support backward compatibility, that is If your projects depend on older versions of the Build Tools.

You need to make TestGetMethod async too and attach await in front of GetIdList(); will unwrap the task to List<int>, So if your helper function is returning Task make sure you have await as you are calling the function async too.

public Task<List<int>> TestGetMethod()
{
    return GetIdList();
}    

async Task<List<int>> GetIdList()
{
    using (HttpClient proxy = new HttpClient())
    {
        string response = await proxy.GetStringAsync("www.test.com");
        List<int> idList = JsonConvert.DeserializeObject<List<int>>();
        return idList;
    }
}

Another option

public async void TestGetMethod(List<int> results)
{
    results = await GetIdList(); // await will unwrap the List<int>
}

For Android 2.0 or later you can use the startForeground() method to start your Service in the foreground.

The documentation says the following:

A started service can use the startForeground(int, Notification) API to put the service in a foreground state, where the system considers it to be something the user is actively aware of and thus not a candidate for killing when low on memory. (It is still theoretically possible for the service to be killed under extreme memory pressure from the current foreground application, but in practice this should not be a concern.)

The is primarily intended for when killing the service would be disruptive to the user, e.g. killing a music player service would stop music playing.

You'll need to supply a Notification to the method which is displayed in the Notifications Bar in the Ongoing section.

This works:

myWindow = window.open('http://www.yahoo.com','myWindow', "width=200, height=200");

using Range with

[Range(typeof(Decimal), "0", "9999", ErrorMessage = "{0} must be a decimal/number between {1} and {2}.")]

[Range(typeof(Decimal),"0.0", "1000000000000000000"]

Hope it will help

JavaScript doesn't have associate arrays. You need to use Objects instead:

var obj = {};
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);?

To get value you can use now different ways:

console.log(obj.name);?
console.log(obj[name]);?
console.log(obj["name"]);?

This will Helpfull.Easy to implement,100% tested.

for(int i=1;i<linecount;i++)
{
 progressBar1.Value = i * progressBar1.Maximum / linecount;  //show process bar counts
 LabelTotal.Text = i.ToString() + " of " + linecount; //show number of count in lable
 int presentage = (i * 100) / linecount;
 LabelPresentage.Text = presentage.ToString() + " %"; //show precentage in lable
 Application.DoEvents(); keep form active in every loop
}

this is pretty simple:

HttpUtility.HtmlDecode(Model.Content)

Another Solution, you could also return a HTMLString, Razor will output the correct formatting:

in the view itself:

@Html.GetSomeHtml()

in controller:

public static HtmlString GetSomeHtml()
{
    var Data = "abc<br/>123";
    return new HtmlString(Data);
}

Because QuerySets implement the Python __or__ operator (|), or union, it just works. As you'd expect, the | binary operator returns a QuerySet so order_by(), .distinct(), and other queryset filters can be tacked on to the end.

combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')

Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.

I think there are several questions buried in this topic:

• How do you implement buildHeap so it runs in O(n) time?
• How do you show that buildHeap runs in O(n) time when implemented correctly?
• Why doesn't that same logic work to make heap sort run in O(n) time rather than O(n log n)?

How do you implement buildHeap so it runs in O(n) time?

Often, answers to these questions focus on the difference between siftUp and siftDown. Making the correct choice between siftUp and siftDown is critical to get O(n) performance for buildHeap, but does nothing to help one understand the difference between buildHeap and heapSort in general. Indeed, proper implementations of both buildHeap and heapSort will only use siftDown. The siftUp operation is only needed to perform inserts into an existing heap, so it would be used to implement a priority queue using a binary heap, for example.

I've written this to describe how a max heap works. This is the type of heap typically used for heap sort or for a priority queue where higher values indicate higher priority. A min heap is also useful; for example, when retrieving items with integer keys in ascending order or strings in alphabetical order. The principles are exactly the same; simply switch the sort order.

The heap property specifies that each node in a binary heap must be at least as large as both of its children. In particular, this implies that the largest item in the heap is at the root. Sifting down and sifting up are essentially the same operation in opposite directions: move an offending node until it satisfies the heap property:

• siftDown swaps a node that is too small with its largest child (thereby moving it down) until it is at least as large as both nodes below it.
• siftUp swaps a node that is too large with its parent (thereby moving it up) until it is no larger than the node above it.

The number of operations required for siftDown and siftUp is proportional to the distance the node may have to move. For siftDown, it is the distance to the bottom of the tree, so siftDown is expensive for nodes at the top of the tree. With siftUp, the work is proportional to the distance to the top of the tree, so siftUp is expensive for nodes at the bottom of the tree. Although both operations are O(log n) in the worst case, in a heap, only one node is at the top whereas half the nodes lie in the bottom layer. So it shouldn't be too surprising that if we have to apply an operation to every node, we would prefer siftDown over siftUp.

The buildHeap function takes an array of unsorted items and moves them until they all satisfy the heap property, thereby producing a valid heap. There are two approaches one might take for buildHeap using the siftUp and siftDown operations we've described.

1. Start at the top of the heap (the beginning of the array) and call siftUp on each item. At each step, the previously sifted items (the items before the current item in the array) form a valid heap, and sifting the next item up places it into a valid position in the heap. After sifting up each node, all items satisfy the heap property.

2. Or, go in the opposite direction: start at the end of the array and move backwards towards the front. At each iteration, you sift an item down until it is in the correct location.

Which implementation for buildHeap is more efficient?

Both of these solutions will produce a valid heap. Unsurprisingly, the more efficient one is the second operation that uses siftDown.

Let h = log n represent the height of the heap. The work required for the siftDown approach is given by the sum

(0 * n/2) + (1 * n/4) + (2 * n/8) + ... + (h * 1).

Each term in the sum has the maximum distance a node at the given height will have to move (zero for the bottom layer, h for the root) multiplied by the number of nodes at that height. In contrast, the sum for calling siftUp on each node is

(h * n/2) + ((h-1) * n/4) + ((h-2)*n/8) + ... + (0 * 1).

It should be clear that the second sum is larger. The first term alone is hn/2 = 1/2 n log n, so this approach has complexity at best O(n log n).

How do we prove the sum for the siftDown approach is indeed O(n)?

One method (there are other analyses that also work) is to turn the finite sum into an infinite series and then use Taylor series. We may ignore the first term, which is zero:

If you aren't sure why each of those steps works, here is a justification for the process in words:

• The terms are all positive, so the finite sum must be smaller than the infinite sum.
• The series is equal to a power series evaluated at x=1/2.
• That power series is equal to (a constant times) the derivative of the Taylor series for f(x)=1/(1-x).
• x=1/2 is within the interval of convergence of that Taylor series.
• Therefore, we can replace the Taylor series with 1/(1-x), differentiate, and evaluate to find the value of the infinite series.

Since the infinite sum is exactly n, we conclude that the finite sum is no larger, and is therefore, O(n).

Why does heap sort require O(n log n) time?

If it is possible to run buildHeap in linear time, why does heap sort require O(n log n) time? Well, heap sort consists of two stages. First, we call buildHeap on the array, which requires O(n) time if implemented optimally. The next stage is to repeatedly delete the largest item in the heap and put it at the end of the array. Because we delete an item from the heap, there is always an open spot just after the end of the heap where we can store the item. So heap sort achieves a sorted order by successively removing the next largest item and putting it into the array starting at the last position and moving towards the front. It is the complexity of this last part that dominates in heap sort. The loop looks likes this:

for (i = n - 1; i > 0; i--) {
    arr[i] = deleteMax();
}

Clearly, the loop runs O(n) times (n - 1 to be precise, the last item is already in place). The complexity of deleteMax for a heap is O(log n). It is typically implemented by removing the root (the largest item left in the heap) and replacing it with the last item in the heap, which is a leaf, and therefore one of the smallest items. This new root will almost certainly violate the heap property, so you have to call siftDown until you move it back into an acceptable position. This also has the effect of moving the next largest item up to the root. Notice that, in contrast to buildHeap where for most of the nodes we are calling siftDown from the bottom of the tree, we are now calling siftDown from the top of the tree on each iteration! Although the tree is shrinking, it doesn't shrink fast enough: The height of the tree stays constant until you have removed the first half of the nodes (when you clear out the bottom layer completely). Then for the next quarter, the height is h - 1. So the total work for this second stage is

h*n/2 + (h-1)*n/4 + ... + 0 * 1.

Notice the switch: now the zero work case corresponds to a single node and the h work case corresponds to half the nodes. This sum is O(n log n) just like the inefficient version of buildHeap that is implemented using siftUp. But in this case, we have no choice since we are trying to sort and we require the next largest item be removed next.

In summary, the work for heap sort is the sum of the two stages: O(n) time for buildHeap and O(n log n) to remove each node in order, so the complexity is O(n log n). You can prove (using some ideas from information theory) that for a comparison-based sort, O(n log n) is the best you could hope for anyway, so there's no reason to be disappointed by this or expect heap sort to achieve the O(n) time bound that buildHeap does.

If you're newing up an element with initializer syntax, you can do something like this:

var row = new HtmlTableRow
{
  Cells =
  {
    new HtmlTableCell
    {
        InnerText = text,
        Attributes = { ["style"] = "min-width: 35px;" }
    },
  }
};

Or if using the CssStyleCollection specifically:

var row = new HtmlTableRow
{
  Cells =
  {
    new HtmlTableCell
    {
        InnerText = text,
        Style = { ["min-width"] = "35px" }
    },
  }
};

You can't modify a collection while iterating it. That way lies madness - most notably, if you were allowed to delete and deleted the current item, the iterator would have to move on (+1) and the next call to next would take you beyond that (+2), so you'd end up skipping one element (the one right behind the one you deleted). You have two options:

• Copy all keys (or values, or both, depending on what you need), then iterate over those. You can use .keys() et al for this (in Python 3, pass the resulting iterator to list). Could be highly wasteful space-wise though.
• Iterate over mydict as usual, saving the keys to delete in a seperate collection to_delete. When you're done iterating mydict, delete all items in to_delete from mydict. Saves some (depending on how many keys are deleted and how many stay) space over the first approach, but also requires a few more lines.

Using dd:

file='/path/to/file'
[[ "$(tail -c 1 "${file}" | tr -dc '\n' | wc -c)" -eq 1 ]] && \
    printf "" | dd  of="${file}" seek=$(($(stat -f "%z" "${file}") - 1)) bs=1 count=1
    #printf "" | dd  of="${file}" seek=$(($(wc -c < "${file}") - 1)) bs=1 count=1

I am using a com.google.android.material.bottomnavigation.BottomNavigationView (not the same as OP's) and I tried a variety of the suggested solutions above, but the only thing that worked was setting app:itemBackground and app:itemIconTint to my selector color worked for me.

    <item android:color="@color/grassBackground" />
</selector>

and I am also using a selected state color for color/bottom_navigation_text_color.xml

Not totally relevant here but for full transparency, my BottomNavigationView style is as follows:

    <style name="BottomNavigationView" parent="Widget.Design.BottomNavigationView">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">@dimen/bottom_navigation_height</item>
        <item name="android:layout_gravity">bottom</item>
        <item name="android:textSize">@dimen/bottom_navigation_text_size</item>
    </style>

import org.hibernate.Criteria;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;


    @Transactional
    public int changepassword(String password, long mobile) {
        // TODO Auto-generated method stub
        session = factory.getCurrentSession();
        Query query = session.createQuery("update User u set u.password='" + password + "' where u.mobile=" + mobile);
        int result = query.executeUpdate();

        return result;
    }
add this code 200% it will work... might scenario is diff but write like this:)

For read a cookie i've made little modifications of the Miquel version that doesn't work for me:

getCookie(name: string) {
        let ca: Array<string> = document.cookie.split(';');
        let cookieName = name + "=";
        let c: string;

        for (let i: number = 0; i < ca.length; i += 1) {
            if (ca[i].indexOf(name, 0) > -1) {
                c = ca[i].substring(cookieName.length +1, ca[i].length);
                console.log("valore cookie: " + c);
                return c;
            }
        }
        return "";

In Java, your "actual" and "logical" size are the same. The run-time fills all array slots with default values upon allocation. So, your a contains 10.

Unfortunately GIT commands like prune and reset or push didn't work for me. Prune worked once and then the issue returned.

The permanent solution which worked for me is to edit a git file manually. Just go to the project's .git folder and then open the file packed-refs in a text editor like Notepad++. Then navigate to the row with the failing branch and update its guid to the expected one.

If you have a message like:

error: cannot lock ref 'refs/remotes/origin/feature/branch_xxx': is at 425ea23facf96f51f412441f41ad488fc098cf23 but expected 383de86fed394ff1a1aeefc4a522d886adcecd79

then in the file find the row with refs/remotes/origin/feature/branch_xxx. The guid there will be the expected (2nd) one - 383de86fed394ff1a1aeefc4a522d886adcecd79. You need to change it to the real (1st) one - 425ea23facf96f51f412441f41ad488fc098cf23.

Repeat for the other failing branches and you'll be good to proceed. Sometimes after re-fetch I had to repeat for the same branches which i already 'fixed' earlier. On re-fetch GIT updates guids and gives you the latest one.

Anyways the issue isn't a show stopper. The branch list gets updated. This is rather a warning.

Another way to clear the recycleview items is to instanciate a new empty adapter.

mRecyclerView.setAdapter(new MyAdapter(this, new ArrayList<MyDataSet>()));

It's probably not the most optimized solution but it's working like a charm.
