Programs & Examples On #Commandfield

To conditionally control view of Template/Command fields, use RowDataBound event of Gridview, like:

    <asp:GridView ID="gv1" OnRowDataBound="gv1_RowDataBound"
              runat="server" AutoGenerateColumns="False" DataKeyNames="Id" >
    <Columns>   
        ...        
           <asp:TemplateField HeaderText="Order Status" 
HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"> 
                 <ItemTemplate> 
                       <asp:Label ID="lblOrderStatus" runat="server"
Text='<%# Bind("OrderStatus") %>'></asp:Label> 
                 </ItemTemplate>
                 <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                 <ItemStyle HorizontalAlign="Center"></ItemStyle>
           </asp:TemplateField>  
        ...

            <asp:CommandField ShowSelectButton="True" SelectText="Select" />

    </Columns>
                </asp:GridView>

and following:

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        Label lblOrderStatus=(Label) e.Row.Cells[4].FindControl("lblOrderStatus");

        if (lblOrderStatus.Text== "Ordered")
        {
            lblOrderStatus.ForeColor = System.Drawing.Color.DarkBlue;
            LinkButton bt = (LinkButton)e.Row.Cells[5].Controls[0];
            bt.Visible = false;
            e.Row.BackColor = System.Drawing.Color.LightGray;
        }
    }

You need to define height of ul or your div and set overflow equals to auto as below:

<ul style="width: 300px; height: 200px; overflow: auto">
  <li>text</li>
  <li>text</li>

Why are you representing them as textareas? This is my favorite:

But if you are using a CMS, there's probably a better plugin. For example, wordpress has an evolved version:

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

DateTime musteriDogum = new DateTime(dogumYil, dogumAy, dogumGun);

int additionalDays = ((DateTime.Now.Year - dogumYil) / 4); //Count of the years with 366 days

int extraDays = additionalDays + ((DateTime.Now.Year % 4 == 0 || musteriDogum.Year % 4 == 0) ? 1 : 0); //We add 1 if this year or year inserted has 366 days

int yearsOld = ((DateTime.Now - musteriDogum).Days - extraDays ) / 365; // Now we extract these extra days from total days and we can divide to 365

You can better achieve it by using the DrawableCompat like this:

Drawable backgroundDrawable = view.getBackground();             
DrawableCompat.setTint(backgroundDrawable, newColor);

Wrote this handy function and put in my bash scripts or ~/.bash_aliases. Tested sync'ing locally on Linux with bash and awk installed. It works

selrsync(){
# selective rsync to sync only certain filetypes;
# based on: https://stackoverflow.com/a/11111793/588867
# Example: selrsync 'tsv,csv' ./source ./target --dry-run
types="$1"; shift; #accepts comma separated list of types. Must be the first argument.
includes=$(echo $types| awk  -F',' \
    'BEGIN{OFS=" ";}
    {
    for (i = 1; i <= NF; i++ ) { if (length($i) > 0) $i="--include=*."$i; } print
    }')
restargs="$@"

echo Command: rsync -avz --prune-empty-dirs --include="*/" $includes --exclude="*" "$restargs"
eval rsync -avz --prune-empty-dirs --include="*/" "$includes" --exclude="*" $restargs
}

Avantages:

short handy and extensible when one wants to add more arguments (i.e. --dry-run).

Example:

selrsync 'tsv,csv' ./source ./target --dry-run

I know that due to this ugly anonymous inner class usage of TransactionTemplate doesn't look nice, but when for some reason we want to have a test method transactional IMHO it is the most flexible option.

In some cases (it depends on the application type) the best way to use transactions in Spring tests is a turned-off @Transactional on the test methods. Why? Because @Transactional may leads to many false-positive tests. You may look at this sample article to find out details. In such cases TransactionTemplate can be perfect for controlling transaction boundries when we want that control.

On Windows 2008 R2, I have seen application crash dumps under either

C:\Users\[Some User]\Microsoft\Windows\WER\ReportArchive

or

C:\ProgramData\Microsoft\Windows\WER\ReportArchive

I don't know how Windows decides which directory to use.

If you are doing some FragmentTransaction in onActivityResult what you can do you can set some boolean value inside onActivityResult then in onResume you can do your FragmentTransaction on the basis of the boolean value. Please refer the code below.

@Override
protected void onResume() {
    super.onResume;
    if(isSwitchFragment){
        isSwitchFragment=false;
        bottomNavigationView.getTabAt(POS_FEED).select();
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == FilterActivity.FILTER_REQUEST_EVENT && data != null) {
        isSwitchFragment=true;
    }
}

Why don't you try the fadeIn() instead of using a show() with delay(). I think what you are trying to do can be done with this. Here is the jQuery code for fadeIn and FadeOut() which also has inbuilt method for delaying the process.

$(document).ready(function(){
   $('element').click(function(){
      //effects take place in 3000ms
      $('element_to_hide').fadeOut(3000);
      $('element_to_show').fadeIn(3000);
   });
}

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

well you could do this, but it's not esp general

'I pity the $fool'.replace('$fool', 'fool')

You could easily write a function that does this intelligently if you really needed to

I have stumbled here twice, and this last time was a unique situation and even though I ditch using copy-item I wanted to post the solution I used.

Had a list of nothing but files with the full path and in majority of the case the files have no extensions. the -Recurse -Force option would not work for me so I ditched copy-item function and fell back to something like below using xcopy as I still wanted to keep it a one liner. Initially I tied with Robocopy but it is apparently looking for a file extension and since many of mine had no extension it considered it a directory.

$filelist = @("C:\Somepath\test\location\here\file","C:\Somepath\test\location\here2\file2")

$filelist | % { echo f | xcopy $_  $($_.Replace("somepath", "somepath_NEW")) }

Hope it helps someone.

Most of the posts that I found will timeout after a second iteration. Particularly if you are looping through a bunch if images as I have been. So to improve the suggestions above here is the entire method:

public System.Drawing.Image DownloadImage(string imageUrl)
    {
        System.Drawing.Image image = null;

        try
        {
            System.Net.HttpWebRequest webRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(imageUrl);
            webRequest.AllowWriteStreamBuffering = true;
            webRequest.Timeout = 30000;
            webRequest.ServicePoint.ConnectionLeaseTimeout = 5000;
            webRequest.ServicePoint.MaxIdleTime = 5000;

            using (System.Net.WebResponse webResponse = webRequest.GetResponse())
            {

                using (System.IO.Stream stream = webResponse.GetResponseStream())
                {
                    image = System.Drawing.Image.FromStream(stream);
                }
            }

            webRequest.ServicePoint.CloseConnectionGroup(webRequest.ConnectionGroupName);
            webRequest = null; 
        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message, ex);

        }


        return image;
    }

I use the combo of these two

    Private Sub sendData(ByVal zpl As String)
    Dim ns As System.Net.Sockets.NetworkStream = Nothing
    Dim socket As System.Net.Sockets.Socket = Nothing
    Dim printerIP As Net.IPEndPoint = Nothing
    Dim toSend As Byte()

    Try
        If printerIP Is Nothing Then
            'set the IP address
            printerIP = New Net.IPEndPoint(IPAddress.Parse(IP_ADDRESS), 9100)
        End If

        'Create a TCP socket
        socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
        'Connect to the printer based on the IP address
        socket.Connect(printerIP)
        'create a new network stream based on the socket connection
        ns = New NetworkStream(socket)

        'convert the zpl command to a byte array
        toSend = System.Text.Encoding.ASCII.GetBytes(zpl)

        'send the zpl byte array over the networkstream to the connected printer
        ns.Write(toSend, 0, toSend.Length)

    Catch ex As Exception
        MessageBox.Show(ex.Message, "Cable Printer", MessageBoxButtons.OKCancel, MessageBoxIcon.Error)
    Finally
        'close the networkstream and then the socket
        If Not ns Is Nothing Then
            ns.Close()
        End If

        If Not socket Is Nothing Then
            socket.Close()
        End If
    End Try
End Sub


Private Function createString() As String
    Dim command As String

    command = "^XA"
    command += "^LH20,25"

    If rdoSmall.Checked = True Then
        command += "^FO1,30^A0,N,25,25^FD"
    ElseIf rdoNormal.Checked = True Then
        command += "^FO1,30^A0,N,35,35^FD"
    Else
        command += "^FO1,30^A0,N,50,50^FD"
    End If

    command += txtInput.Text
    command += "^FS"
    command += "^XZ"

    Return command

End Function

You must remember to use single quotes for char constants. So use

if (answer == 'y') return true;

Rather than

if (answer == "y") return true;

I tested this and it works

This should work

public class StackOverflowTest
{  
    public static void main(String args[])
    {
        int theNumber = 42;
        System.out.println("Your number is " + theNumber + "!");
    }
}

Just to save you too much typos:

foreach($group_membership as $username){
        $username->items = array(additional array to add);
    }
    print_r($group_membership);

The Eclipse team with The Open University have prepared the following document, which includes creating proxy classes with tests. It might be what you are looking for.

http://www.eclipse.org/webtools/community/education/web/t320/Generating_a_client_from_WSDL.pdf

Everything is included in the Dynamic Web Project template.

In the project create a Web Service Client. This starts a wizard that has you point out a wsdl url and creates the client with tests for you.

The user guide (targeted at indigo though) for this task is found at http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.jst.ws.cxf.doc.user%2Ftasks%2Fcreate_client.html.

Worked for me

    data () {
        return {
            userInfo: null,
            offers: null
        }
    },

    watch: {
        '$route'() {
            this.userInfo = null
            this.offers = null
            this.loadUserInfo()
            this.getUserOffers()
        }
    }

As this is specifically tagged for jQuery -

$("#myElement")[0].getBoundingClientRect();

or

$("#myElement").get(0).getBoundingClientRect();

(These are functionally identical, in some older browsers .get() was slightly faster)

Note that if you try to get the values via jQuery calls then it will not take into account any css transform values, which can give unexpected results...

Note 2: In jQuery 3.0 it has changed to using the proper getBoundingClientRect() calls for its own dimension calls (see the jQuery Core 3.0 Upgrade Guide) - which means that the other jQuery answers will finally always be correct - but only when using the new jQuery version - hence why it's called a breaking change...

if you want to find out the exact error go to the following path in your project: /app/build/reports/lint-results-release-fatal.html(or .xml). The easiest way is if you go to the xml file, it will show you exactly what the error is including its position of the error in your either java class or xml file. Turning off the lint checks is not a good idea, they're there for a reason. Instead, go to:

    /app/build/reports/lint-results-release-fatal.html or 
    /app/build/reports/lint-results-release-fatal.xml

and fix it.

You can assign it to a hidden field, and retrieve it using

var value= Request.Form["value"]

All of the following assume that your cursor is on the first line:

Using normal mappings:

3Shift+J

Using Ex commands:

:,+2j

Which is an abbreviation of

:.,.+2 join

Which can also be entered by the following shortcut:

3:j

An even shorter Ex command:

:j3

This is what I did on the controller

var collectionDate = '2002-04-26T09:00:00';
var date = new Date(collectionDate);
//then pushed all my data into an array $scope.rows which I then used in the directive

I ended up formatting the date to my desired pattern on the directive as follows.

var data = new google.visualization.DataTable();
                    data.addColumn('date', 'Dates');
                    data.addColumn('number', 'Upper Normal');
                    data.addColumn('number', 'Result');
                    data.addColumn('number', 'Lower Normal');
                    data.addRows(scope.rows);
                    var formatDate = new google.visualization.DateFormat({pattern: "dd/MM/yyyy"});
                    formatDate.format(data, 0);
//set options for the line chart
var options = {'hAxis': format: 'dd/MM/yyyy'}

//Instantiate and draw the chart passing in options
var chart = new google.visualization.LineChart($elm[0]);
                    chart.draw(data, options);

This gave me dates ain the format of dd/MM/yyyy (26/04/2002) on the x axis of the chart.

The question has already been marked as answered, But I guess the question states that the person wants to remove multiple columns from a DataTable.

So for that, here is what I did, when I came across the same problem.

string[] ColumnsToBeDeleted = { "col1", "col2", "col3", "col4" };

foreach (string ColName in ColumnsToBeDeleted)
{
    if (dt.Columns.Contains(ColName))
        dt.Columns.Remove(ColName);
}

<button my-directive="push">Push to Go</button>

app.directive("myDirective", function() {
    return {
        restrict : "A",
         link: function(scope, elm, attrs) {
                elm.bind('click', function(event) {

                    alert("You pressed button: " + event.target.getAttribute('my-directive'));
                });
        }
    };
});

here is what I did

I'm using directive as html attribute and I passed parameter as following in my HTML file. my-directive="push" And from the directive I retrieved it from the Mouse-click event object. event.target.getAttribute('my-directive').

How about using ES6 template literals?

var a = "cat";
var b = "fat";
console.log(`my ${a} is ${b}`); //notice back-ticked string

More about template literals...

Try using something like this:

<link rel="image_src" href="http://yoursite.com/graphics/yourimage.jpg" /link>`

Seems to work just fine on Firefox as long as you use a full path to your image.

Trouble is it get vertically offset downward for some reason. Image is 200 x 200 as recommended somewhere I read.

1. Download the package
2. unzip it if it is zipped
3. cd into the directory containing setup.py
4. If there are any installation instructions contained in documentation contianed herein, read and follow the instructions OTHERWISE
5. type in python setup.py install

You may need administrator privileges for step 5. What you do here thus depends on your operating system. For example in Ubuntu you would say sudo python setup.py install

EDIT- thanks to kwatford (see first comment)

To bypass the need for administrator privileges during step 5 above you may be able to make use of the --user flag. In this way you can install the package only for the current user.

The docs say:

Files will be installed into subdirectories of site.USER_BASE (written as userbase hereafter). This scheme installs pure Python modules and extension modules in the same location (also known as site.USER_SITE). Here are the values for UNIX, including Mac OS X:

More details can be found here: http://docs.python.org/2.7/install/index.html

The web.config transforms that are part of Visual Studio 2010 use XSLT in order to "transform" the current web.config file into its .Debug or .Release version.

In your .Debug/.Release files, you need to add the following parameter in your connection string fields:

xdt:Transform="SetAttributes" xdt:Locator="Match(name)"

This will cause each connection string line to find the matching name and update the attributes accordingly.

Note: You won't have to worry about updating your providerName parameter in the transform files, since they don't change.

Here's an example from one of my apps. Here's the web.config file section:

<connectionStrings>
      <add name="EAF" connectionString="[Test Connection String]" />
</connectionString>

And here's the web.config.release section doing the proper transform:

<connectionStrings>
      <add name="EAF" connectionString="[Prod Connection String]"
           xdt:Transform="SetAttributes"
           xdt:Locator="Match(name)" />
</connectionStrings>

One added note: Transforms only occur when you publish the site, not when you simply run it with F5 or CTRL+F5. If you need to run an update against a given config locally, you will have to manually change your Web.config file for this.

For more details you can see the MSDN documentation

• The SELECT statement cannot contain a subquery in the FROM clause.

Your workaround would be to create a view for each of your subqueries.

Then access those views from within your view view_credit_status

There is a difference in terms of performance between HQL and criteriaQuery, everytime you fire a query using criteriaQuery, it creates a new alias for the table name which does not reflect in the last queried cache for any DB. This leads to an overhead of compiling the generated SQL, taking more time to execute.

Regarding fetching strategies [http://www.hibernate.org/315.html]

• Criteria respects the laziness settings in your mappings and guarantees that what you want loaded is loaded. This means one Criteria query might result in several SQL immediate SELECT statements to fetch the subgraph with all non-lazy mapped associations and collections. If you want to change the "how" and even the "what", use setFetchMode() to enable or disable outer join fetching for a particular collection or association. Criteria queries also completely respect the fetching strategy (join vs select vs subselect).
• HQL respects the laziness settings in your mappings and guarantees that what you want loaded is loaded. This means one HQL query might result in several SQL immediate SELECT statements to fetch the subgraph with all non-lazy mapped associations and collections. If you want to change the "how" and even the "what", use LEFT JOIN FETCH to enable outer-join fetching for a particular collection or nullable many-to-one or one-to-one association, or JOIN FETCH to enable inner join fetching for a non-nullable many-to-one or one-to-one association. HQL queries do not respect any fetch="join" defined in the mapping document.

There is also change that Eclipse Project is somehow corrupted. Usually case like this Eclipse is added some duplicated .jars in your project and those .jars are usually same as Maven Dependency .jars.

If your project look like below example there is huge change that Maven Dependencies are duplicated and should be removed manually.

e.g. (Project Explorer View)
src/main/java
src/test/java
spring-boot-vaadin.jar
spring-aop.jar
Maven Dependencies
  spring-boot-vaadin.jar
  spring-aop.jar
etc...

...and this is cure :-)

Just remove all REPO_M2/... paths and update project.

The difference between this two tables ItemBack1 and #ItemBack1 is that the first on is persistent (permanent) where as the other is temporary.

Now if take a look at your question again

Is it necessary to Use # for creating temp table in sql server?

The answer is Yes, because without this preceding # the table will not be a temporary table, it will be independent of all sessions and scopes.

For me, as I was storing many values within a single print call, the solution was to create a separate variable to store the data as a tuple and then call the print function.

x = (f"{id}", f"{name}", f"{age}")
print(x) 

You will not be able to find out the password he chose. However, you may create a new user or set a new password to the existing user.

Usually, you can login as the postgres user:

Open a Terminal and do sudo su postgres. Now, after entering your admin password, you are able to launch psql and do

CREATE USER yourname WITH SUPERUSER PASSWORD 'yourpassword';

This creates a new admin user. If you want to list the existing users, you could also do

\du

to list all users and then

ALTER USER yourusername WITH PASSWORD 'yournewpass';

3 Steps you can follow

1. chmod -R 775 <repo path>  
   ---> change permissions of repository
   

2. chown -R apache:apache <repo path>  
   ---> change owner of svn repository
   

3. chcon -R -t httpd_sys_content_t <repo path>  
   ----> change SELinux security context of the svn repository
   

Use jQuery. You need to capture the click event and then go on to the website.

$("#myHref").on('click', function() {_x000D_
  alert("inside onclick");_x000D_
  window.location = "http://www.google.com";_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<a href="#" id="myHref">Click me</a>

Use System.Diagnostics.Process to launch an instance of Notepad.exe.

for more advanced python editing consider installing the simplefold vim plugin. it allows you do advanced code folding using regular expressions. i use it to fold my class and method definitions for faster editing.

The approved answer from George Claghorn worked great for simply inserting text at the cursor position. If the user had selected text though, and you want that text to be replaced (the default experience with most text), you need to make a small change when setting the 'back' variable.

Also, if you don't need to support older versions of IE, modern versions support textarea.selectionStart, so you can take out all of the browser detection, and IE-specific code.

Here is a simplified version that works for Chrome and IE11 at least, and handles replacing selected text.

function insertAtCaret(areaId, text) {
    var txtarea = document.getElementById(areaId);
    var scrollPos = txtarea.scrollTop;
    var caretPos = txtarea.selectionStart;

    var front = (txtarea.value).substring(0, caretPos);
    var back = (txtarea.value).substring(txtarea.selectionEnd, txtarea.value.length);
    txtarea.value = front + text + back;
    caretPos = caretPos + text.length;
    txtarea.selectionStart = caretPos;
    txtarea.selectionEnd = caretPos;
    txtarea.focus();
    txtarea.scrollTop = scrollPos;
}

You can simply handle the NO_DATA_FOUND exception by setting your variable to NULL. This way, only one query is required.

    v_column my_table.column%TYPE;

BEGIN

    BEGIN
      select column into v_column from my_table where ...;
    EXCEPTION
      WHEN NO_DATA_FOUND THEN
        v_column := NULL;
    END;

    ... use v_column here
END;

Your web.xml ends with <web-app>, but must end with </web-app>

Which by the way is almost literally what the exception tells you.

I faced the same issue. If you are posting an angular form with normal post then you will face this issue, as angular don't allow you to set values for the options in the way you have used. If you get the value of "form.type" then you will find the right value. You have to post the angular object it self not the form post.

Well, you could erase() the first character too (note that erase() modifies the string):

m_VirtualHostName.erase(0, 1);
m_VirtualHostName.erase(m_VirtualHostName.size() - 1);

But in this case, a simpler way is to take a substring:

m_VirtualHostName = m_VirtualHostName.substr(1, m_VirtualHostName.size() - 2);

Be careful to validate that the string actually has at least two characters in it first...

A String in Java can be converted to "binary" with its getBytes(Charset) method.

byte[] encoded = "????????!".getBytes(StandardCharsets.UTF_8);

The argument to this method is a "character-encoding"; this is a standardized mapping between a character and a sequence of bytes. Often, each character is encoded to a single byte, but there aren't enough unique byte values to represent every character in every language. Other encodings use multiple bytes, so they can handle a wider range of characters.

Usually, the encoding to use will be specified by some standard or protocol that you are implementing. If you are creating your own interface, and have the freedom to choose, "UTF-8" is an easy, safe, and widely supported encoding.

• It's easy, because rather than including some way to note the encoding of each message, you can default to UTF-8.
• It's safe, because UTF-8 can encode any character that can be used in a Java character string.
• It's widely supported, because it is one of a small handful of character encodings that is required to be present in any Java implementation, all the way down to J2ME. Most other platforms support it too, and it's used as a default in standards like XML.

Use the os.path module.

os.path.join( "C:", "meshes", "as" )

Or use raw strings

r"C:\meshes\as"

I would also recommend no spaces in the path or file names. And you could use double backslashes in your strings.

"C:\\meshes\\as.jpg"

Try this...

def is_int(x):
  absolute = abs(x)
  rounded = round(absolute)
  return absolute - rounded == 0

Use child.setLocation(0, 0) on the button, and parent.setLayout(null). Instead of using setBounds(...) on the JFrame to size it, consider using just setSize(...) and letting the OS position the frame.

//JPanel
JPanel pnlButton = new JPanel();
//Buttons
JButton btnAddFlight = new JButton("Add Flight");

public Control() {

    //JFrame layout
    this.setLayout(null);

    //JPanel layout
    pnlButton.setLayout(null);

    //Adding to JFrame
    pnlButton.add(btnAddFlight);
    add(pnlButton);

    // postioning
    pnlButton.setLocation(0,0);

You need to have org/name dirs at /usr/share/stuff and place your org.name package sources at this dir.

I solved my problem that way. Thank you for suggestions for improvements. Example in C#.

string dd, mm, aa, trc, data;
dd = nData.Text.Substring(0, 2);
mm = nData.Text.Substring(3, 2);
aa = nData.Text.Substring(6, 4);
trc = "-";
data = aa + trc + mm + trc + dd;

"Select * From bdPedidos Where Data Like '%" + data + "%'";

To understand it in a easier way, following are the diffrences between JSON object and JSON array:

Link to Tabular Difference : https://i.stack.imgur.com/GIqI9.png

JSON Array

1. Arrays in JSON are used to organize a collection of related items
   (Which could be JSON objects)
2.  Array values must be of type string, number, object, array, boolean or null
3.  Syntax: 
           [ "Ford", "BMW", "Fiat" ]
4.  JSON arrays are surrounded by square brackets []. 
    **Tip to remember**  :  Here, order of element is important. That means you have 
    to go straight like the shape of the bracket i.e. straight lines. 
   (Note :It is just my logic to remember the shape of both.) 
5.  Order of elements is important. Example:  ["Ford","BMW","Fiat"] is not 
    equal to ["Fiat","BMW","Ford"]
6.  JSON can store nested Arrays that are passed as a value.

JSON Object

1.  JSON objects are written in key/value pairs.
2.  Keys must be strings, and values must be a valid JSON data type (string, number, 
    object, array, boolean or null).Keys and values are separated by a colon.
    Each key/value pair is separated by a comma.
3.  Syntax:
         { "name":"Somya", "age":25, "car":null }
4.  JSON objects are surrounded by curly braces {} 
    Tip to remember : Here, order of element is not important. That means you can go 
    the way you like. Therefore the shape of the braces i.e. wavy. 
    (Note : It is just my logic to remember the shape of both.)
5.  Order of elements is not important. 
    Example:  { rollno: 1, firstname: 'Somya'} 
                   is equal to 
             { firstname: 'Somya', rollno: 1}
6.  JSON can store nested objects in JSON format in addition to nested arrays.

An easy way to determine whether something is "pass by reference" is whether you can write a "swap" function. For example, in C, you can do:

void swap(int *i, int *j)
{
    int t;
    t = *i;
    *i = *j;
    *j = t;
}

If you can't do the equivalent of that in JavaScript, it is not "pass by reference".

The error message is fairly self-explanatory

(a,b,c,d,e) = line.split()

expects line.split() to yield 5 elements, but in your case, it is only yielding 1 element. This could be because the data is not in the format you expect, a rogue malformed line, or maybe an empty line - there's no way to know.

To see what line is causing the issue, you could add some debug statements like this:

if len(line.split()) != 11:
    print line

As Martin suggests, you might also be splitting on the wrong delimiter.

use os.path.join() to construct your paths - It's neater:

import os
import sys
rootdir = sys.argv[1]
for root, subFolders, files in os.walk(rootdir):
    for folder in subFolders:
        outfileName = os.path.join(root,folder,"py-outfile.txt")
        folderOut = open( outfileName, 'w' )
        print "outfileName is " + outfileName
        for file in files:
            filePath = os.path.join(root,file)
            toWrite = open( filePath).read()
            print "Writing '" + toWrite + "' to" + filePath
            folderOut.write( toWrite )
        folderOut.close()

you can use if() in place of decode() in mySql as follows This query will print all even id row.

mysql> select id, name from employee where id in
-> (select if(id%2=0,id,null) from employee);

I also made a solution, which is working with Stacks. It's a more modular approach so u don't have to specify each Fragment and Detail Fragment in your FragmentPagerAdapter. It's build on top of the Example from ActionbarSherlock which derives if I'm right from the Google Demo App.

/**
 * This is a helper class that implements the management of tabs and all
 * details of connecting a ViewPager with associated TabHost.  It relies on a
 * trick.  Normally a tab host has a simple API for supplying a View or
 * Intent that each tab will show.  This is not sufficient for switching
 * between pages.  So instead we make the content part of the tab host
 * 0dp high (it is not shown) and the TabsAdapter supplies its own dummy
 * view to show as the tab content.  It listens to changes in tabs, and takes
 * care of switch to the correct paged in the ViewPager whenever the selected
 * tab changes.
 * 
 * Changed to support more Layers of fragments on each Tab.

Add this for back button functionality in your MainActivity:

@Override
public void onBackPressed() {
  if (!mTabsAdapter.back(getSupportFragmentManager())) {
    super.onBackPressed();
  }
}

If u like to save the Fragment State when it get's removed. Let your Fragment implement the interface SaveStateBundle return in the function a bundle with your save state. Get the bundle after instantiation by this.getArguments().

You can instantiate a tab like this:

mTabsAdapter.addTab(mTabHost.newTabSpec("firstTabTag").setIndicator("First Tab Title"),
                FirstFragmentActivity.FirstFragmentFragment.class, null);

works similiar if u want to add a Fragment on top of a Tab Stack. Important: I think, it won't work if u want to have 2 instances of same class on top of two Tabs. I did this solution quick together, so I can only share it without providing any experience with it.

Yes, It's deprecated. Spent yesterday rewriting code to use Window.open and PostMessage instead.

Thanks to everyone who posted in this thread. I created a module that includes the Defer() object described earlier as well as a few other objects built upon it. They all leverage Promises and the neat Promise call-back syntax to implement communication/event handling within a program.

• Defer: Promise that can be resolved failed remotely (outside of its body)
• Delay: Promise that is resolved automatically after a given time
• TimeOut: Promise that fails automatically after a given time.
• Cycle: Re-triggerable promise to manage events with the Promise syntax
• Queue: Execution queue based on Promise chaining.

Fun fact!

The 'modulus' operation is defined as:

a % n ==> a - (a/n) * n

Ref:Modular Arithmetic

So you could roll your own, although it will be FAR slower than the built in % operator:

public static int Mod(int a, int n)
{
    return a - (int)((double)a / n) * n;
}

Edit: wow, misspoke rather badly here originally, thanks @joren for catching me

Now here I'm relying on the fact that division + cast-to-int in C# is equivalent to Math.Floor (i.e., it drops the fraction), but a "true" implementation would instead be something like:

public static int Mod(int a, int n)
{
    return a - (int)Math.Floor((double)a / n) * n;
}

In fact, you can see the differences between % and "true modulus" with the following:

var modTest =
    from a in Enumerable.Range(-3, 6)
    from b in Enumerable.Range(-3, 6)
    where b != 0
    let op = (a % b)
    let mod = Mod(a,b)
    let areSame = op == mod
    select new 
    { 
        A = a,
        B = b,
        Operator = op, 
        Mod = mod, 
        Same = areSame
    };
Console.WriteLine("A      B     A%B   Mod(A,B)   Equal?");
Console.WriteLine("-----------------------------------");
foreach (var result in modTest)
{
    Console.WriteLine(
        "{0,-3} | {1,-3} | {2,-5} | {3,-10} | {4,-6}", 
        result.A,
        result.B,
        result.Operator, 
        result.Mod, 
        result.Same);
}

Results:

A      B     A%B   Mod(A,B)   Equal?

If you have a Red Hat server use yum. apt-get is only for Debian, Ubuntu and some other related linux.

Why would you want to use apt-get anyway? (It seems like you know what yum is.)

It's better to have a proper JSON format instead of directly using the one converted from XML.

[
  {
    "number": "2013-W45",
    "days": [
      {
        "dow": "1",
        "templateDay": "Monday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          },
          {
            "name": "work 9-5",

          }
        ]
      },
      {
        "dow": "2",
        "templateDay": "Tuesday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          }
        ]
      }
    ]
  }
]

This will make things much easier and easy to loop through.

Now you can write the loop as -

<div ng-repeat="week in myData">
   <div ng-repeat="day in week.days">
      {{day.dow}} - {{day.templateDay}}
      <b>Jobs:</b><br/> 
       <ul>
         <li ng-repeat="job in day.jobs"> 
           {{job.name}} 
         </li>
       </ul>
   </div>
</div>

Saving (w/o exception handling code):

FileOutputStream fos = context.openFileOutput(fileName, Context.MODE_PRIVATE);
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(this);
os.close();
fos.close();

Loading (w/o exception handling code):

FileInputStream fis = context.openFileInput(fileName);
ObjectInputStream is = new ObjectInputStream(fis);
SimpleClass simpleClass = (SimpleClass) is.readObject();
is.close();
fis.close();

Keep the acceptable values in a HashSet and check if your string exists using the contains method:

Set<String> accept = new HashSet<String>(Arrays.asList(new String[] {"john", "mary", "peter"}));
if (accept.contains(some_string)) {
    //...
}

One .Net build with x86/x64 Dependencies

While all other answers give you a solution to make different Builds according to the platform, I give you an option to only have the "AnyCPU" configuration and make a build that works with your x86 and x64 dlls.

You have to write some plumbing code for this.

Resolution of correct x86/x64-dlls at runtime

Steps:

1. Use AnyCPU in csproj
2. Decide if you only reference the x86 or the x64 dlls in your csprojs. Adapt the UnitTests settings to the architecture settings you have chosen. It's important for debugging/running the tests inside VisualStudio.
3. On Reference-Properties set Copy Local & Specific Version to false
4. Get rid of the architecture warnings by adding this line to the first PropertyGroup in all of your csproj files where you reference x86/x64: <ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch>None</ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch>

5. Add this postbuild script to your startup project, use and modify the paths of this script sp that it copies all your x86/x64 dlls in corresponding subfolders of your build bin\x86\ bin\x64\

   xcopy /E /H /R /Y /I /D $(SolutionDir)\YourPathToX86Dlls $(TargetDir)\x86 xcopy /E /H /R /Y /I /D $(SolutionDir)\YourPathToX64Dlls $(TargetDir)\x64

   --> When you would start application now, you get an exception that the assembly could not be found.

6. Register the AssemblyResolve event right at the beginning of your application entry point

   AppDomain.CurrentDomain.AssemblyResolve += TryResolveArchitectureDependency;
   

   withthis method:

   /// <summary>
   /// Event Handler for AppDomain.CurrentDomain.AssemblyResolve
   /// </summary>
   /// <param name="sender">The app domain</param>
   /// <param name="resolveEventArgs">The resolve event args</param>
   /// <returns>The architecture dependent assembly</returns>
   public static Assembly TryResolveArchitectureDependency(object sender, ResolveEventArgs resolveEventArgs)
   {
       var dllName = resolveEventArgs.Name.Substring(0, resolveEventArgs.Name.IndexOf(","));
   
       var anyCpuAssemblyPath = $".\\{dllName}.dll";
   
       var architectureName = System.Environment.Is64BitProcess ? "x64" : "x86";
   
       var assemblyPath = $".\\{architectureName}\\{dllName}.dll";
   
       if (File.Exists(assemblyPath))
       {
           return Assembly.LoadFrom(assemblyPath);
       }
   
       return null;
   }
   

7. If you have unit tests make a TestClass with a Method that has an AssemblyInitializeAttribute and also register the above TryResolveArchitectureDependency-Handler there. (This won't be executed sometimes if you run single tests inside visual studio, the references will be resolved not from the UnitTest bin. Therefore the decision in step 2 is important.)

Benefits:

• One Installation/Build for both platforms

Drawbacks: - No errors at compile time when x86/x64 dlls do not match. - You should still run test in both modes!

Optionally create a second executable that is exclusive for x64 architecture with Corflags.exe in postbuild script

Other Variants to try out: - You don't need the AssemblyResolve event handler if you assure that the right dlls are copied to your binary folder at start (Evaluate Process architecture -> move corresponding dlls from x64/x86 to bin folder and back.) - In Installer evaluate architecture and delete binaries for wrong architecture and move the right ones to the bin folder.

Just for those interested you can avoid writing custom function by passing NULL as last parameter (if you do not intend to do extra processing of returned data).
In this case default internal function is used.

    if (curl)
    {   
        fp = fopen(outfilename,"wb");
        curl_easy_setopt(curl, CURLOPT_URL, url);
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, NULL);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
        res = curl_easy_perform(curl);
        curl_easy_cleanup(curl);
        fclose(fp);
    }   
    return 0;
}

You can simply do it with train_test_split() method available in Scikit learn:

from sklearn.model_selection import train_test_split 
train, test = train_test_split(X, test_size=0.25, stratify=X['YOUR_COLUMN_LABEL']) 

I have also prepared a short GitHub Gist which shows how stratify option works:

Here is a quick easy way to just get the name of the url.

            var urlHost = HttpContext.Current.Request.Url.Host;

            var xUrlHost = urlHost.Split('.');
            foreach(var thing in xUrlHost)
            {
                if(thing != "www" && thing != "com")
                {
                    urlHost = thing;
                }
            }

If you want to append to the file, open it with 'a'. If you want to seek through the file to find the place where you should insert the line, use 'r+'. (docs)

The listen socket on a server can use linger with time 0 to have access to binding back to the socket immediately and to reset any clients whose connections are not yet finished connecting. TIME_WAIT is something that is only interesting when you have a multi-path network and can end up with miss-ordered packets or otherwise are dealing with odd network packet ordering/arrival-timing.

For those of you who are building on a MacOS, and don't like leaving your password in clear text on your machine, you can use the keychain tool to store the credentials and then inject it into the build. Credits go to Viktor Eriksson. https://pilloxa.gitlab.io/posts/safer-passwords-in-gradle/

Make sure that the field has this attribute in its html.

ClientIDMode="Static"

and then use this in your script:

$("#NameOfYourTextBox").change(function () {_x000D_
                 $(this).val($(this).val().toUpperCase());_x000D_
             });

There is a simple solution for you called unique_together which does exactly what you want.

For example:

class MyModel(models.Model):
  field1 = models.CharField(max_length=50)
  field2 = models.CharField(max_length=50)

  class Meta:
    unique_together = ('field1', 'field2',)

And in your case:

class Volume(models.Model):
  id = models.AutoField(primary_key=True)
  journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal")
  volume_number = models.CharField('Volume Number', max_length=100)
  comments = models.TextField('Comments', max_length=4000, blank=True)

  class Meta:
    unique_together = ('journal_id', 'volume_number',)

I have used the following code, and I am getting the right result...

<?php
    function currentPageURL() {
        $curpageURL = 'http';
        if ($_SERVER["HTTPS"] == "on") {
            $curpageURL.= "s";
        }
        $curpageURL.= "://";
        if ($_SERVER["SERVER_PORT"] != "80") {
            $curpageURL.= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
        } 
        else {
            $curpageURL.= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
        }
        return $curpageURL;
    }
    echo currentPageURL();
?>

For small numbers n%3 == 0 will be fine. For very large numbers I propose to calculate the cross sum first and then check if the cross sum is a multiple of 3:

def is_divisible_by_3(number):
    if sum(map(int, str(number))) % 3 != 0:
        my_bool = False
    return my_bool

height: 100% works if you give a fixed size to the parent element.

I used just the lines below and it worked. I just wanted to compile VirtualBox and VMWare WorkStation using kernel 4.8.10 on Ubuntu 14.04. Initially, most things were not working for example graphics and networking. I was lucky that VMWare workstation requested for gcc 6.2.0. I couldn't start my Genymotion Android emulators because virtualbox was down. Will post results later if necessary.

Source: Use NATURAL FULL JOIN to compare two tables in SQL by Lukas Eder

Clever approach of using NATURAL FULL JOIN to detect the same/different rows between two tables.

Example 1 - status flag:

SELECT t1.*, t2.*, CASE WHEN t1 IS NULL OR t2 IS NULL THEN 'Not equal' ELSE 'Equal' END
FROM t1
NATURAL FULL JOIN t2;

Example 2 - filtering rows

SELECT *
FROM (SELECT 't1' AS t1, t1.* FROM t1) t1 
NATURAL FULL JOIN (SELECT 't2' AS t2, t2.* FROM t2) t2 
WHERE t1 IS NULL OR t2 IS NULL -- show differences
--WHERE  t1 IS NOT NULL AND t2 IS NOT NULL    -- show the same

Here is a way to change the owner on ALL DBS (excluding System)

EXEC sp_msforeachdb'
USE [?]
IF ''?'' <> ''master'' AND ''?'' <> ''model'' AND ''?'' <> ''msdb'' AND ''?'' <> ''tempdb''
BEGIN
 exec sp_changedbowner ''sa''
END
'

this is working with Swift 4 :

if let soundURL = Bundle.main.url(forResource: "note3", withExtension: "wav") {
                var mySound: SystemSoundID = 0
                AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
                // Play
                AudioServicesPlaySystemSound(mySound);
            }

You can set label's border via its underlying CALayer property:

#import <QuartzCore/QuartzCore.h>

myLabel.layer.borderColor = [UIColor greenColor].CGColor
myLabel.layer.borderWidth = 3.0

Swift 5:

myLabel.layer.borderColor = UIColor.darkGray.cgColor
myLabel.layer.borderWidth = 3.0

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.

1. You can halt server, corrupt work of other people by memory consuming script without even knowing it.
2. You will not be seeing mistakes where something, let's say, infinite loop happened, and it will be harder to diagnose.
3. Such site may be easily DoSed by single user, when requesting pages with long execution time

KEY POINT'S

1. Do not start a session on the return page.
2. Don't use session variable and not include header.php which user session variable
3. Just make a link go to home page or profile page after insert payment info and status

You can use includes from the Ramda library:

i.e:

R.includes({ name: 'Fred' }, [{ name: 'Fred' }]); //=> true

        if(params) {
            let reqParams = {};        
            Object.keys(params).map(k =>{
                reqParams[k] = params[k];
            });
            reqData['params'] = reqParams;
        }
        return reqData;
    }

and send request

this.http.get(this.getUrl(url), this.setHeaders(params))

Its work with NestJS backend, with other I don't know.

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

From the @LearnRPG answer but with 1.0:

 // send to current request socket client
 socket.emit('message', "this is a test");

 // sending to all clients, include sender
 io.sockets.emit('message', "this is a test"); //still works
 //or
 io.emit('message', 'this is a test');

 // sending to all clients except sender
 socket.broadcast.emit('message', "this is a test");

 // sending to all clients in 'game' room(channel) except sender
 socket.broadcast.to('game').emit('message', 'nice game');

 // sending to all clients in 'game' room(channel), include sender
 // docs says "simply use to or in when broadcasting or emitting"
 io.in('game').emit('message', 'cool game');

 // sending to individual socketid, socketid is like a room
 socket.broadcast.to(socketid).emit('message', 'for your eyes only');

To answer @Crashalot comment, socketid comes from:

var io = require('socket.io')(server);
io.on('connection', function(socket) { console.log(socket.id); })

Sku is an int, can't be defaulted to string "sku". Please check Optional URI Parameters and Default Values

Ian Kemp has the answer (have some points btw..), this is to simply add some meat to one of his steps.

The reason I ended up here was that dev's machines were building fine, but the build server simply wasn't pulling down the packages required (empty packages folder) and therefore the build was failing. Logging onto the build server and manually building the solution worked, however.

To fulfil the second of Ians 3 point steps (running nuget restore), you can create an MSBuild target running the exec command to run the nuget restore command, as below (in this case nuget.exe is in the .nuget folder, rather than on the path), which can then be run in a TeamCity build step (other CI available...) immediately prior to building the solution

<Target Name="BeforeBuild">
  <Exec Command="..\.nuget\nuget restore ..\MySolution.sln"/>
</Target>

For the record I'd already tried the "nuget installer" runner type but this step was hanging on web projects (worked for DLL's and Windows projects)

Try entering the url inside the function

$location.url('http://www.google.com')

JVM is the Java Virtual Machine – it actually runs Java ByteCode.

JRE is the Java Runtime Environment – it contains a JVM, among other things, and is what you need to run a Java program.

JDK is the Java Development Kit – it is the JRE, but with javac (which is what you need to compile Java source code) and other programming tools added.

OpenJDK is a specific JDK implementation.

The CSS @import rule does just that. E.g.,

@import url('/css/common.css');
@import url('/css/colors.css');

You can use .length after the selector to see if it matched any elements, like this:

if($("#" + name).length == 0) {
  //it doesn't exist
}

The full version:

$("li.friend").live('click', function(){
  name = $(this).text();
  if($("#" + name).length == 0) {
    $("div#chatbar").append("<div class='labels'><div id='" + name + "' style='display:none;'></div>" + name + "</div>");
  } else {
    alert('this record already exists');
  }
});

Or, the non-jQuery version for this part (since it's an ID):

$("li.friend").live('click', function(){
  name = $(this).text();
  if(document.getElementById(name) == null) {
    $("div#chatbar").append("<div class='labels'><div id='" + name + "' style='display:none;'></div>" + name + "</div>");
  } else {
    alert('this record already exists');
  }
});

Firebase.remove() like probably most Firebase methods is asynchronous, thus you have to listen to events to know when something happened:

parent = ref.parent()
parent.on('child_removed', function (snapshot) {
    // removed!
})
ref.remove()

According to Firebase docs it should work even if you lose network connection. If you want to know when the change has been actually synchronized with Firebase servers, you can pass a callback function to Firebase.remove method:

ref.remove(function (error) {
    if (!error) {
        // removed!
    }
}

The other examples here work fine for the old versions of ui-router (>=0.3.x) but all state events, such as $stateChangeStart, are deprecated as of 1.0. The new ui-router 1.0 code uses the $transitions service. So you need to inject $transitions into your component then use the $transitions.onBefore method as the code below demonstrates.

$transitions.onBefore({}, function(transition) {
  return confirm("Are you sure you want to leave this page?");
});

This is just a super simple example. The $transitions service can accept more complicated responses such as promises. See the HookResult type for more information.

On Ubuntu Server 16, I have the same problem with python27. Try this:

Change

from pip import main
if __name__ == '__main__':
    sys.exit(main())

To

from pip._internal import main
if __name__ == '__main__':
    sys.exit(main())

Another weird subtle difference on GitHub is that changes to forks are not counted in your activity log until your changes are pulled into the original repo. What's more, to change a fork into a proper clone, you have to contact Github support, apparently.

From Why are my contributions not showing up:

Commit was made in a fork

Commits made in a fork will not count toward your contributions. To make them count, you must do one of the following:

Open a pull request to have your changes merged into the parent repository. To detach the fork and turn it into a standalone repository on GitHub, contact GitHub Support. If the fork has forks of its own, let support know if the forks should move with your repository into a new network or remain in the current network. For more information, see "About forks."

It is nice to verify that the code you pushed actually got committed.

You can get a log of changes on a bare repository by explicitly setting the path using the --relative option.

$ cd test_repo
$ git log --relative=/

This will show you the committed changes as if this was a regular git repo.

My alias settings in ~/.bashrc file for git diff:

alias gdca='git diff --cached' # diff between your staged file and the last commit
alias gdcc='git diff HEAD{,^}' # diff between your latest two commits

Here is a alternative solution that should survive if the client pc goes into sleep mode.

If you have a huge amount of logged in users then use this cautiously as this could eat a lot of server memory.

After you login (i do this in the LoggedIn event of the login control)

Dim loggedOutAfterInactivity As Integer = 999 'Minutes

'Keep the session alive as long as the authentication cookie.
Session.Timeout = loggedOutAfterInactivity

'Get the authenticationTicket, decrypt and change timeout and create a new one.
Dim formsAuthenticationTicketCookie As HttpCookie = _
        Response.Cookies(FormsAuthentication.FormsCookieName)

Dim ticket As FormsAuthenticationTicket = _
        FormsAuthentication.Decrypt(formsAuthenticationTicketCookie.Value)
Dim newTicket As New FormsAuthenticationTicket(
        ticket.Version, ticket.Name, ticket.IssueDate, 
        ticket.IssueDate.AddMinutes(loggedOutAfterInactivity), 
        ticket.IsPersistent, ticket.UserData)
formsAuthenticationTicketCookie.Value = FormsAuthentication.Encrypt(newTicket)

Here is a fairly easy to understand version using method syntax:

IEnumerable<JoinPair> outerLeft =
    lefts.SelectMany(l => 
        rights.Where(r => l.Key == r.Key)
              .DefaultIfEmpty(new Item())
              .Select(r => new JoinPair { LeftId = l.Id, RightId = r.Id }));

Try each_with_index.

Insted of

drawer.setDrawerListener(toggle);

You can use

drawer.addDrawerListener(toggle);

First of all if you are in < 5.3PHP then no. You've got a ton of problems to tackle.

I am surprised that none has mentioned the intl library, the one that has good support for unicode, graphemes, string operations , localisation and many more, see below.

I will quote some information about unicode support in PHP by Elizabeth Smith's slides at PHPBenelux'14

INTL

Good:

• Wrapper around ICU library
• Standardised locales, set locale per script
• Number formatting
• Currency formatting
• Message formatting (replaces gettext)
• Calendars, dates, timezone and time
• Transliterator
• Spoofchecker
• Resource bundles
• Convertors
• IDN support
• Graphemes
• Collation
• Iterators

Bad:

• Does not support zend_multibite
• Does not support HTTP input output conversion
• Does not support function overloading

mb_string

• Enables zend_multibyte support
• Supports transparent HTTP in/out encoding
• Provides some wrappers for funtionallity such as strtoupper

ICONV

• Primary for charset conversion
• Output buffer handler
• mime encoding functionality
• conversion
• some string helpers (len, substr, strpos, strrpos)
• Stream Filter stream_filter_append($fp, 'convert.iconv.ISO-2022-JP/EUC-JP')

DATABASES

• mysql: Charset and collation on tables and on connection (not the collation). Also don't use mysql - msqli or PDO
• postgresql: pg_set_client_encoding
• sqlite(3): Make sure it was compiled with unicode and intl support

Some other Gotchas

• You cannot use unicode filenames with PHP and windows unless you use a 3rd part extension.
• Send everything in ASCII if you are using exec, proc_open and other command line calls
• Plain text is not plain text, files have encodings
• You can convert files on the fly with the iconv filter

I ll update this answer in case things change features added and so on.

It occurs basically when _Layout.cshtml is without:

@RenderSection("scripts", required: false)

or with

@RenderSection("scripts")  

WITHOUT

required: false

So, Just add @RenderSection("scripts", required: false) in _Layout.cshtml and it works specially for those developers who works with Kendoui genarated projects.

If you are using a GNU compiler, the compiler can assemble a list of dependencies for you. Makefile fragment:

depend: .depend

.depend: $(SRCS)
        rm -f "$@"
        $(CC) $(CFLAGS) -MM $^ -MF "$@"

include .depend

or

depend: .depend

.depend: $(SRCS)
        rm -f "$@"
        $(CC) $(CFLAGS) -MM $^ > "$@"

include .depend

where SRCS is a variable pointing to your entire list of source files.

There is also the tool makedepend, but I never liked it as much as gcc -MM

You need seek to the beginning of the file before writing and then use file.truncate() if you want to do inplace replace:

import re

myfile = "path/test.xml"

with open(myfile, "r+") as f:
    data = f.read()
    f.seek(0)
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))
    f.truncate()

The other way is to read the file then open it again with open(myfile, 'w'):

with open(myfile, "r") as f:
    data = f.read()

with open(myfile, "w") as f:
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))

Neither truncate nor open(..., 'w') will change the inode number of the file (I tested twice, once with Ubuntu 12.04 NFS and once with ext4).

By the way, this is not really related to Python. The interpreter calls the corresponding low level API. The method truncate() works the same in the C programming language: See http://man7.org/linux/man-pages/man2/truncate.2.html

For me this worked: (added into .ssh\config)

• [ is the same as the test builtin, and works like the test binary (man test)
  • works about the same as [ in all the other sh-based shells in many UNIX-like environments
  • only supports a single condition. Multiple tests with the bash && and || operators must be in separate brackets.
  • doesn't natively support a 'not' operator. To invert a condition, use a ! outside the first bracket to use the shell's facility for inverting command return values.
  • == and != are literal string comparisons
• [[ is a bash
  • is bash-specific, though others shells may have implemented similar constructs. Don't expect it in an old-school UNIX sh.
  • == and != apply bash pattern matching rules, see "Pattern Matching" in man bash
  • has a =~ regex match operator
  • allows use of parentheses and the !, &&, and || logical operators within the brackets to combine subexpressions

Aside from that, they're pretty similar -- most individual tests work identically between them, things only get interesting when you need to combine different tests with logical AND/OR/NOT operations.

The name of the DOM function is actually getElementsByClassName, not getElementByClassName, simply because more than one element on the page can have the same class, hence: Elements.

The return value of this will be a NodeList instance, or a superset of the NodeList (FF, for instance returns an instance of HTMLCollection). At any rate: the return value is an array-like object:

var y = document.getElementsByClassName('foo');
var aNode = y[0];

If, for some reason you need the return object as an array, you can do that easily, because of its magic length property:

var arrFromList = Array.prototype.slice.call(y);
//or as per AntonB's comment:
var arrFromList = [].slice.call(y);

As yckart suggested querySelector('.foo') and querySelectorAll('.foo') would be preferable, though, as they are, indeed, better supported (93.99% vs 87.24%), according to caniuse.com:

• querySelector(all)
• getElementsByClassName
• Don't use w3schools to learn something
• Refer to MDN for accurate information

Another way, is simply add the headers to your route:

router.get('/', function(req, res) {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE'); // If needed
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type'); // If needed
    res.setHeader('Access-Control-Allow-Credentials', true); // If needed

    res.send('cors problem fixed:)');
});

angular 5 :

 getImage(id: string): Observable<Blob> {
    return this.httpClient.get('http://myip/image/'+id, {responseType: "blob"});
}

This is an old question but this is what I ended up with; it enumerates the enumerable only once, but does create lists for each of the partitions. It doesn't suffer from unexpected behavior when ToArray() is called as some of the implementations do:

    public static IEnumerable<IEnumerable<T>> Partition<T>(IEnumerable<T> source, int chunkSize)
    {
        if (source == null)
        {
            throw new ArgumentNullException("source");
        }

        if (chunkSize < 1)
        {
            throw new ArgumentException("Invalid chunkSize: " + chunkSize);
        }

        using (IEnumerator<T> sourceEnumerator = source.GetEnumerator())
        {
            IList<T> currentChunk = new List<T>();
            while (sourceEnumerator.MoveNext())
            {
                currentChunk.Add(sourceEnumerator.Current);
                if (currentChunk.Count == chunkSize)
                {
                    yield return currentChunk;
                    currentChunk = new List<T>();
                }
            }

            if (currentChunk.Any())
            {
                yield return currentChunk;
            }
        }
    }

[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*

This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.

Are you looking for floor?

var num = 1.42482;
var num2 = 1;
var fnum = Math.floor(num).toFixed(2);
var fnum2 = Math.floor(num2).toFixed(2);
alert(fnum + " and " + fnum2); //both values will be 1.00

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

add --spring.profiles.active=production

Example:

java -jar file.jar --spring.profiles.active=production

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

In VBA, the != operator is the Not operator, like this:

If Not strTest = "" Then ...

I solved the problem by creating a symbolic link to the library. I.e.

The actual library resides in

/usr/local/mysql/lib

And then I created a symbolic link in

/usr/lib

Using the command:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

so that I have the following mapping:

ls -l libmysqlclient.18.dylib 
lrwxr-xr-x  1 root  wheel  44 16 Jul 14:01 libmysqlclient.18.dylib -> /usr/local/mysql/lib/libmysqlclient.18.dylib

That was it. After that everything worked fine.

EDIT:

Notice, that since MacOS El Capitan the System Integrity Protection (SIP, also known as "rootless") will prevent you from creating links in /usr/lib/. You could disable SIP by following these instructions, but you can create a link in /usr/local/lib/ instead:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

Welcome to bash. It's an old, dark and mysterious thing, capable of great magic. :-)

The option you're asking about is for the find command though, not for bash. From your command line, you can man find to see the options.

The one you're looking for is -o for "or":

  list="$(find /home/user/Desktop -name '*.bmp' -o -name '*.txt')"

That said ... Don't do this. Storage like this may work for simple filenames, but as soon as you have to deal with special characters, like spaces and newlines, all bets are off. See ParsingLs for details.

$ touch 'one.txt' 'two three.txt' 'foo.bmp'
$ list="$(find . -name \*.txt -o -name \*.bmp -type f)"
$ for file in $list; do if [ ! -f "$file" ]; then echo "MISSING: $file"; fi; done
MISSING: ./two
MISSING: three.txt

Pathname expansion (globbing) provides a much better/safer way to keep track of files. Then you can also use bash arrays:

$ a=( *.txt *.bmp )
$ declare -p a
declare -a a=([0]="one.txt" [1]="two three.txt" [2]="foo.bmp")
$ for file in "${a[@]}"; do ls -l "$file"; done
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 one.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 two three.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 foo.bmp

The Bash FAQ has lots of other excellent tips about programming in bash.

if( myVariable ) 
{ 
    //mayVariable is not : 
    //null 
    //undefined 
    //NaN 
    //empty string ("") 
    //0 
    //false 
}

You may be looking for the special HTML character, 
 .

You can use this to get a line break, and it can be inserted immediately following the last character in the current line. One place this is especially useful is if you want to include multiple lines in a list within a title or alt label.

Right-click on your project's name in Eclipse's Project Explorer, then click Run As followed by Run on Server. Click the Next button. Make sure your project's name is listed in the Configured: column on the right. If it is, then you should be able to access it with this URL:

http://localhost:8085/projectname/

Additionally, whenever you make new additions (such as new JSPs, graphics or other resources) to your project, be sure to refresh the project by clicking on its name and then hitting F5. Otherwise Eclipse does not know that those new resources are available and will not make them available to Tomcat to serve.

Floats don't have a height so the containing div has a height of zero.

<div style="background-color:black; overflow:hidden;zoom:1" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
</div>

overflow:hidden clears the float for most browsers.

zoom:1 clears the float for IE.

Another way based on a merge of serveral responses here before :

docker-compose file :

version: "3"
services:
    db:
      container_name: db
      image: mysql
      ports:
       - "3306:3306"  
      environment:
         - MYSQL_ROOT_PASSWORD=mysql
         - MYSQL_DATABASE=db

      volumes:
         - /home/user/db/mysql/data:/var/lib/mysql
         - /home/user/db/mysql/init:/docker-entrypoint-initdb.d/:ro

where /home/user.. is a shared folder on the host

And in the /home/user/db/mysql/init folder .. just drop one sql file, with any name, for example init.sql containing :

CREATE DATABASE mydb;
GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'%' IDENTIFIED BY 'mysql';
GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'localhost' IDENTIFIED BY 'mysql';
USE mydb
CREATE TABLE CONTACTS (
    [ ... ]
);
INSERT INTO CONTACTS VALUES ...
[ ... ]

According to the official mysql documentation, you can put more than one sql file in the docker-entrypoint-initdb.d, they are executed in the alphabetical order

    select v.SQL_TEXT,
           v.PARSING_SCHEMA_NAME,
           v.FIRST_LOAD_TIME,
           v.DISK_READS,
           v.ROWS_PROCESSED,
           v.ELAPSED_TIME,
           v.service
      from v$sql v
where to_date(v.FIRST_LOAD_TIME,'YYYY-MM-DD hh24:mi:ss')>ADD_MONTHS(trunc(sysdate,'MM'),-2)

where clause is optional. You can sort the results according to FIRST_LOAD_TIME and find the records up to 2 months ago.

You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:

System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);

string server = builder.DataSource;
string database = builder.InitialCatalog;

or

System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();

builder.ConnectionString = connectionString;

string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;

For me it sufficed to simply run

gem update

Please everyone note that you can set a cookie from a subdomain on a domain.

(sent in the response for requesting subdomain.mydomain.com)

Set-Cookie: name=value; Domain=mydomain.com // GOOD

But you CAN'T set a cookie from a domain on a subdomain.

(sent in the response for requesting mydomain.com)

Set-Cookie: name=value; Domain=subdomain.mydomain.com // Browser rejects cookie

WHY ?

According to the specifications RFC 6265 section 5.3.6 Storage Model

If the canonicalized request-host does not domain-match the domain-attribute: Ignore the cookie entirely and abort these steps.

and RFC 6265 section 5.1.3 Domain Matching

Domain Matching

A string domain-matches a given domain string if at least one of the following conditions hold:

1. The domain string and the string are identical. (Note that both the domain string and the string will have been canonicalized to lower case at this point.)

2. All of the following conditions hold:

   • The domain string is a suffix of the string.

   • The last character of the string that is not included in the domain string is a %x2E (".") character.

   • The string is a host name (i.e., not an IP address).

So "subdomain.mydomain.com" domain-matches "mydomain.com", but "mydomain.com" does NOT domain-match "subdomain.mydomain.com"

I had the same issue, and solved it the following way. My issue came because I imported a project from Git, which wasn't having the project file. So Eclipse was not recognizing the project as a java one. Ctrl+click was not working and so there was the F3 issue.

Solution:(not a direct one. but solved my issue)

• import -> projects from git -> from URI -> select the new project wizard

• so an empty project with src folder will be created.

• then copy all the src files in to the folder manually.

Edit: I just noted that you are trying to use a gmail address as the from value. This is not going to work, and the ISP is right in overwriting it. If you want to redirect the replies to your outgoing messages, use reply-to.

A workaround for valid addresses that works with many ISPs:

try adding a fifth parameter to your mail() command:

mail($to,$subject,$message,$headers,"-f [email protected]");

First Build your Project and if it was successful, right click on the "model.tt" file and choose run custom tool. It will fix it.

Again Build your project and point to "model.context.tt" run custom tool. it will update DbSet lists.

exec sp_lock

This query should give you existing locks.

exec sp_who SPID -- will give you some info

Having spids, you could check activity monitor(processes tab) to find out what processes are locking the tables ("details" for more info and "kill process" to kill it).

You are mixing mysqli and mysql extensions, which will not work.

You need to use

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); 

mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");   

mysqli has many improvements over the original mysql extension, so it is recommended that you use mysqli.

There is also a GUI based method.

You can use gitk.

1. Run:

   $ gitk --all
   

2. Right click on a commit of a branch and select Mark this commit in the pop-up menu.

3. Right click on a commit of another branch and select Diff this -> marked commit or Diff marked commit -> this.

Then there will be a changed files list in the right bottom panel and diff details in the left bottom panel.

No this is not possible. The only solution will be to have regular backups. This is very important.

First of all, login to your database and check whether the database table which you want to import is not available on your database.

If it is available, delete the table using the command. Else it will throw an error while importing the table.

DROP TABLE Table_Name;

Then, move to the folder in which you have the .sql file to import and run the following command from your terminal

mysql -u username -p  databasename  < yourtable.sql

The terminal will ask you to enter the password. Enter it and check the database.

Is this what you're looking for?

Try wrapping your entire select in brackets, then running a count(*) on that

select count(*)
from
(
   select m.id
   from Monitor as m 
    inner join Monitor_Request as mr 
       on mr.Company_ID=m.Company_id   group by m.Company_id
    having COUNT(m.Monitor_id)>=5
) myNewTable

Multiple files can be selected and then uploaded using the
<input type='file' name='file[]' multiple>
The sample php script that does the uploading:

<html>
<title>Upload</title>
<?php
    session_start();
    $target=$_POST['directory'];
        if($target[strlen($target)-1]!='/')
                $target=$target.'/';
            $count=0;
            foreach ($_FILES['file']['name'] as $filename) 
            {
                $temp=$target;
                $tmp=$_FILES['file']['tmp_name'][$count];
                $count=$count + 1;
                $temp=$temp.basename($filename);
                move_uploaded_file($tmp,$temp);
                $temp='';
                $tmp='';
            }
    header("location:../../views/upload.php");
?>
</html>

The selected files are received as an array with

$_FILES['file']['name'][0] storing the name of first file.
$_FILES['file']['name'][1] storing the name of second file.
and so on.

To really convert from a string to a number properly, you need to use an instance of NSNumberFormatter configured for the locale from which you're reading the string.

Different locales will format numbers differently. For example, in some parts of the world, COMMA is used as a decimal separator while in others it is PERIOD — and the thousands separator (when used) is reversed. Except when it's a space. Or not present at all.

It really depends on the provenance of the input. The safest thing to do is configure an NSNumberFormatter for the way your input is formatted and use -[NSFormatter numberFromString:] to get an NSNumber from it. If you want to handle conversion errors, you can use -[NSFormatter getObjectValue:forString:range:error:] instead.

From memory, Excel uses the machine-specific ANSI encoding. So this would be Windows-1252 for a EN-US installation, 1251 for Russian, etc.

You have written like

@Html.RadioButtonFor(model => model.gender, "Male", new { @checked = true }) and
@Html.RadioButtonFor(model => model.gender, "Female", new { @checked = true })

Here you have taken gender as a Enum type and you have written the value for the radio button as a string type- change "Male" to 0 and "Female" to 1.

Use the menu selection Navigate -> Test, or Ctrl+Shift+T (Shift+?+T on Mac). This will go to the existing test class, or offer to generate it for you through a little wizard.

As also noted by John Szakmeister and VasiliNovikov, the shortest command to get the full diff from master's perspective on your branch is:

git diff master...

This uses your local copy of master.

To compare a specific file use:

git diff master... filepath

I don't think WPF supports what you are trying to achieve i.e. assigning method to a button using method's name or btn1.Click = "btn1_Click". You will have to use approach suggested in above answers i.e. register button click event with appropriate method btn1.Click += btn1_Click;

largest=none
smallest =none 
While True :
          num =raw_input ('enter a number ') 
          if num =="done ": break 
          try :
           inp =int (inp) 
          except:
              Print'Invalid input' 
           if largest is none :
               largest=inp
           elif inp>largest:
                largest =none 
           print 'maximum', largest

          if smallest is none:
               smallest =none
          elif inp<smallest :
               smallest =inp

SGML parsers (or XML parsers in the case of XHTML) can handle — without having to process the DTD (which doesn't matter to browsers as they just slurp tag soup), while — is easier for humans to read and write in the source code.

Personally, I would stick to a literal em-dash and ensure that my character encoding settings were consistent.

Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.

It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.

The first one is the JAR of the logmanager module generated during the package phase by jar:jar (because the module has a packaging of type jar). The second one is the assembly generated by assembly:assembly and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies).

I get an error when I double-click on the first jar:

Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.

If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>

So logmanager-0.1.0.jar is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager (this is what the error is saying, check the content of the jar).

A slightly different error when I double-click the jar-with-dependencies.jar:

Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar

Again, if you configured the assembly plugin as suggested, you have something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>

With this setup, logmanager-0.1.0-jar-with-dependencies.jar contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF doesn't contain a Main-Class entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.

So, my suggestion would be to remove the configuration element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <!-- nothing here -->
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>org.sample.App</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Of course, replace org.sample.App with the class you want to have executed. Little bonus, I've bound assembly:single to the package phase so you don't have to run assembly:assembly anymore. Just run mvn install and the assembly will be produced during the standard build.

So, please update your pom.xml with the configuration given above and run mvn clean install. Then, cd into the target directory and try again:

java -jar logmanager-0.1.0-jar-with-dependencies.jar

If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF file and the relevant part of your pom.xml (the plugins configuration parts). Also please post the result of:

java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager

to demonstrate it's working fine on the command line (regardless of what eclipse is saying).

EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

Please check the log , you will get more detailed information .

Use the below command to tail the error log

tail -100 /usr/local/var/mysql/<user_name>.local.err

For me , one of the directory is missing , once created the server has started .

Here's the most straightforward way to create a drawing application with canvas:

1. Attach a mousedown, mousemove, and mouseup event listener to the canvas DOM
2. on mousedown, get the mouse coordinates, and use the moveTo() method to position your drawing cursor and the beginPath() method to begin a new drawing path.
3. on mousemove, continuously add a new point to the path with lineTo(), and color the last segment with stroke().
4. on mouseup, set a flag to disable the drawing.

From there, you can add all kinds of other features like giving the user the ability to choose a line thickness, color, brush strokes, and even layers.

JDBC does not support this option (although a specific DB driver may offer this). Anyway, there should not be a problem with loading all file contents into memory.

Neither text-align:center nor display:inline-block worked for me on their own, but combining both did:

ul {
  text-align: center;
}
li {
  display: inline-block;
}

Is cscript a 3rd party app? I suggest trying Microsoft Scripting, where you can use a programming language (JScript, VBS) to check on things like List Available Disk Space.

The scripting infrastructure is present on all current Windows versions (including 2008).

You can actually put anything inside a toolbar. See the below code.

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:background="@color/colorPrimary">

</android.support.v7.widget.Toolbar>

Between the above toolbar tag you can put almost anything. That is the benefit of using a Toolbar.

Here is another go at it .. Adding more to the accepted answer possibly more comprehensive .. of course switch -case will make it look for elegant.

Well, I'm late.

In your image, the paper is white, while the background is colored. So, it's better to detect the paper is Saturation(???) channel in HSV color space. Take refer to wiki HSL_and_HSV first. Then I'll copy most idea from my answer in this Detect Colored Segment in an image.

Main steps:

1. Read into BGR
2. Convert the image from bgr to hsv space
3. Threshold the S channel
4. Then find the max external contour(or do Canny, or HoughLines as you like, I choose findContours), approx to get the corners.

This is my result:

The Python code(Python 3.5 + OpenCV 3.3):

#!/usr/bin/python3
# 2017.12.20 10:47:28 CST
# 2017.12.20 11:29:30 CST

import cv2
import numpy as np

##(1) read into  bgr-space
img = cv2.imread("test2.jpg")

##(2) convert to hsv-space, then split the channels
hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
h,s,v = cv2.split(hsv)

##(3) threshold the S channel using adaptive method(`THRESH_OTSU`) or fixed thresh
th, threshed = cv2.threshold(s, 50, 255, cv2.THRESH_BINARY_INV)

##(4) find all the external contours on the threshed S
#_, cnts, _ = cv2.findContours(threshed, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
cnts = cv2.findContours(threshed, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)[-2]

canvas  = img.copy()
#cv2.drawContours(canvas, cnts, -1, (0,255,0), 1)

## sort and choose the largest contour
cnts = sorted(cnts, key = cv2.contourArea)
cnt = cnts[-1]

## approx the contour, so the get the corner points
arclen = cv2.arcLength(cnt, True)
approx = cv2.approxPolyDP(cnt, 0.02* arclen, True)
cv2.drawContours(canvas, [cnt], -1, (255,0,0), 1, cv2.LINE_AA)
cv2.drawContours(canvas, [approx], -1, (0, 0, 255), 1, cv2.LINE_AA)

## Ok, you can see the result as tag(6)
cv2.imwrite("detected.png", canvas)

I would agree with @evillinux, It would be best to make your background image semi transparent so it supports < ie8

The other suggestions of using another div are also a great option, and it's the way to go if you want to do this in css. For example if the site had such features as selecting your own background color. I would suggest using a filter for older IE. eg:

filter:Alpha(opacity=50)

This is the documentation that you want: http://msdn.microsoft.com/en-us/library/aa292114(VS.71).aspx

I guess the answer is, yes, there is an equivalent that will accomplish the same thing, integrated with Windows security.

Did you try <br/>, <br><br/> or simply \n ? <br> should be supported according to this source, though.

Supported HTML tags

I faced the same error. When I installed Unity Framework for Dependency Injection the new references of the Http and HttpFormatter has been added in my configuration. So here are the steps I followed.

I ran following command on nuGet Package Manager Console: PM> Install-Package Microsoft.ASPNet.WebAPI -pre

And added physical reference to the dll with version 5.0

A good reason is for security - this can prevent CSRF attacks because this header cannot be added to the AJAX request cross domain without the consent of the server via CORS.

Only the following headers are allowed cross domain:

• Accept
• Accept-Language
• Content-Language
• Last-Event-ID
• Content-Type

any others cause a "pre-flight" request to be issued in CORS supported browsers.

Without CORS it is not possible to add X-Requested-With to a cross domain XHR request.

If the server is checking that this header is present, it knows that the request didn't initiate from an attacker's domain attempting to make a request on behalf of the user with JavaScript. This also checks that the request wasn't POSTed from a regular HTML form, of which it is harder to verify it is not cross domain without the use of tokens. (However, checking the Origin header could be an option in supported browsers, although you will leave old browsers vulnerable.)

New Flash bypass discovered

You may wish to combine this with a token, because Flash running on Safari on OSX can set this header if there's a redirect step. It appears it also worked on Chrome, but is now remediated. More details here including different versions affected.

OWASP Recommend combining this with an Origin and Referer check:

This defense technique is specifically discussed in section 4.3 of Robust Defenses for Cross-Site Request Forgery. However, bypasses of this defense using Flash were documented as early as 2008 and again as recently as 2015 by Mathias Karlsson to exploit a CSRF flaw in Vimeo. But, we believe that the Flash attack can't spoof the Origin or Referer headers so by checking both of them we believe this combination of checks should prevent Flash bypass CSRF attacks. (NOTE: If anyone can confirm or refute this belief, please let us know so we can update this article)

However, for the reasons already discussed checking Origin can be tricky.

Update

Written a more in depth blog post on CORS, CSRF and X-Requested-With here.

We were getting the same error - so this may be useful to some.

For us the cause was super simple. An interface change confused an end user and they were pressing the back button in the browser at a 'bad' time after a form submission (sure we should probably have used a PRG pattern, but we didn't).

We fixed the issue and the user is no longer pressing the back button. Problem solved.

Using GitPython will give you a good python interface to Git.

For example, after installing it (pip install gitpython), for cloning a new repository you can use clone_from function:

from git import Repo

Repo.clone_from(git_url, repo_dir)

See the GitPython Tutorial for examples on using the Repo object.

Note: GitPython requires git being installed on the system, and accessible via system's PATH.

MySQL use HAVING statement for this tasks.

Your query would look like this:

SELECT g.group_id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m USING(group_id)
GROUP BY g.group_id
HAVING members > 4

example when references have different names

SELECT g.id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m ON g.id = m.group_id
GROUP BY g.id
HAVING members > 4

Also, make sure that you set indexes inside your database schema for keys you are using in JOINS as it can affect your site performance.

Another way to effectively do this is:

git fetch
git branch -d branchB
git branch -t branchB origin/branchB

Because it's a lower case -d, it will only delete it if the data will still exist somewhere. It's similar to @kkoehne's answer except it doesn't force. Because of the -t it will set up the remote again.

I had a slightly different need than OP, which was to create a new feature branch off develop (or master), after merging a pull request. That can be accomplished in a one-liner without force, but it doesn't update the local develop branch. It's just a matter of checking out a new branch and having it be based off origin/develop:

git checkout -b new-feature origin/develop

Further from @finnmglas, the Java answer as of 2021 is:

    if (Build.VERSION.SDK_INT >= 29)
        btn.getBackground().setColorFilter(new BlendModeColorFilter(color, BlendMode.MULTIPLY));
    else
        btn.getBackground().setColorFilter(color, PorterDuff.Mode.MULTIPLY);

Be aware that the function File.GetLastWriteTime does not always work as expected, the values are sometimes not instantaneously updated by the OS. You may get an old Timestamp, even if the file has been modified right before.

The behaviour may vary between OS versions. For example, this unit test worked well every time on my developer machine, but it always fails on our build server.

  [TestMethod]
  public void TestLastModifiedTimeStamps()
  {
     var tempFile = Path.GetTempFileName();
     var lastModified = File.GetLastWriteTime(tempFile);
     using (new FileStream(tempFile, FileMode.Create, FileAccess.Write, FileShare.None))
     {

     }
     Assert.AreNotEqual(lastModified, File.GetLastWriteTime(tempFile));
  }

See File.GetLastWriteTime seems to be returning 'out of date' value

Your options:

a) live with the occasional omissions.

b) Build up an active component realising the observer pattern (eg. a tcp server client structure), communicating the changes directly instead of writing / reading files. Fast and flexible, but another dependency and a possible point of failure (and some work, of course).

c) Ensure the signalling process by replacing the content of a dedicated signal file that other processes regularly read. It´s not that smart as it´s a polling procedure and has a greater overhead than calling File.GetLastWriteTime, but if not checking the content from too many places too often, it will do the work.

If you want to set primary and secondary progress color to horizontal progress bar programmatically in android then use below snippet

int[][] states = new int[][] {
                        new int[] {-android.R.attr.state_checked},
                        new int[] {android.R.attr.state_checked},
                };

                int[] secondaryColor = new int[] {
                        context.getResources().getColor(R.color.graph_line_one),
                        Color.RED,
                };

                int[] primaryColor = new int[] {
                        context.getResources().getColor(R.color.middle_progress),
                        Color.BLUE,
                };
                progressbar.setProgressTintList(new ColorStateList(states, primaryColor));
                progressbar.setSecondaryProgressTintList(new ColorStateList(states, secondaryColor));

Just paste the below formula in any of the cells, it will render the path of the file:

=LEFT(CELL("filename"),FIND("]",CELL("filename"),1))

The above formula works in any version of Excel.

There is no options in javascript to find the height of a cross domain iframe height but you can done something like this with the help of some server side programming. I used PHP for this example

<code>
    <?php
$output = file_get_contents('http://yourdomain.com');
?>
<div id='iframediv'>
    <?php echo $output; ?>
</div>

<iframe style='display:none' id='iframe' src="http://yourdomain.com" width="100%" marginwidth="0" height="100%" marginheight="0" align="top" scrolling="auto" frameborder="0" hspace="0" vspace="0"> </iframe>

<script>
if(window.attachEvent) {
    window.attachEvent('onload', iframeResizer);
} else {
    if(window.onload) {
        var curronload = window.onload;
        var newonload = function(evt) {
            curronload(evt);
            iframeResizer(evt);
        };
        window.onload = newonload;
    } else {
        window.onload = iframeResizer;
    }
}
   function iframeResizer(){
        var result = document.getElementById("iframediv").offsetHeight;

        document.getElementById("iframe").style.height = result;
        document.getElementById("iframediv").style.display = 'none';
        document.getElementById("iframe").style.display = 'inline';
    }
</script>
</code>

If it's still not working here's what may certainly be a solution: encode the mp4 with compression format H.264. If you encode it with format mpeg4 or divx or else it will not work on IE9 and may as well crash Google Chrome. To do that, I use Any Video Converter freeware. But it could be done with any good video tool out there.

I've been trying all solutions listed here and tried other workaround for days but the problem lied in the way I created my mp4. IE9 does not decode other format than H.264.

Hope this helps, Jimmy

I think your only option here is a constant. With that said - don't use it - stick with nulls instead of bogus dates.

create table atable
(
  atableID int IDENTITY(1, 1) PRIMARY KEY CLUSTERED,
  Modified datetime DEFAULT '1/1/1753'
)

Try this instead:

SUM(CASE WHEN ValueDate > @startMonthDate THEN cash ELSE 0 END)

Explanation

Your CASE expression has incorrect syntax. It seems you are confusing the simple CASE expression syntax with the searched CASE expression syntax. See the documentation for CASE:

The CASE expression has two formats:

• The simple CASE expression compares an expression to a set of simple expressions to determine the result.
• The searched CASE expression evaluates a set of Boolean expressions to determine the result.

You want the searched CASE expression syntax:

CASE
     WHEN Boolean_expression THEN result_expression [ ...n ] 
     [ ELSE else_result_expression ] 
END

As a side note, if performance is an issue you may find that this expression runs more quickly if you rewrite using a JOIN and GROUP BY instead of using a dependent subquery.

After looking around on Google for a long time, trying out several solutions, both CSS, JavaScript and JQuery, i found that most of them were using an Image as the button. Some of them were hard to use, but i did manage to piece together something that ended out working out for me.

The important parts for me was:

• The Browse button had to be a Button (not an image).
• The button had to have a hover effect (to make it look nice).
• The Width of both the Text and the button had to be easy to adjust.
• The solution had to work in IE8, FF, Chrome and Safari.

This is the solution i came up with. And hope it can be of use to others as well.

Change the width of .file_input_textbox to change the width of the textbox.

Change the width of both .file_input_div, .file_input_button and .file_input_button_hover to change the width of the button. You might need to tweak a bit on the positions also. I never figured out why...

To test this solution, make a new html file and paste the content into it.

<html>
<head>

<style type="text/css">

.file_input_textbox {height:25px;width:200px;float:left; }
.file_input_div     {position: relative;width:80px;height:26px;overflow: hidden; }
.file_input_button  {width: 80px;position:absolute;top:0px;
                     border:1px solid #F0F0EE;padding:2px 8px 2px 8px; font-weight:bold; height:25px; margin:0px; margin-right:5px; }
.file_input_button_hover{width:80px;position:absolute;top:0px;
                     border:1px solid #0A246A; background-color:#B2BBD0;padding:2px 8px 2px 8px; height:25px; margin:0px; font-weight:bold; margin-right:5px; }
.file_input_hidden  {font-size:45px;position:absolute;right:0px;top:0px;cursor:pointer;
                     opacity:0;filter:alpha(opacity=0);-ms-filter:"alpha(opacity=0)";-khtml-opacity:0;-moz-opacity:0; }
</style>
</head>
<body>
    <input type="text" id="fileName" class="file_input_textbox" readonly="readonly">
 <div class="file_input_div">
  <input id="fileInputButton" type="button" value="Browse" class="file_input_button" />
  <input type="file" class="file_input_hidden" 
      onchange="javascript: document.getElementById('fileName').value = this.value" 
      onmouseover="document.getElementById('fileInputButton').className='file_input_button_hover';"
      onmouseout="document.getElementById('fileInputButton').className='file_input_button';" />
</div>
</body>
</html>

Why can't you use absolute positioning? Vertical-align does not work (except for tables). Make your container's position: relative. Then absolutely position the internal divs using bottom: 0; Should work like a charm.

EDIT By zoidberg (i will update the answer instead)

<div style="position:relative; border: 1px solid red;width: 40px; height: 40px;">
   <div style="border:1px solid green;position: absolute; bottom: 0; left: 0; width: 20px; height: 20px;"></div>
   <div style="border:1px solid blue;position: absolute; bottom: 0; left: 20px; width: 20px height: 20px;"></div>
</div>

You can also use "joblib" for this purpose.

import joblib
print joblib.cpu_count()

This method will give you the number of cpus in the system. joblib needs to be installed though. More information on joblib can be found here https://pythonhosted.org/joblib/parallel.html

Alternatively you can use numexpr package of python. It has lot of simple functions helpful for getting information about the system cpu.

import numexpr as ne
print ne.detect_number_of_cores()

If you get a message from git complaining about the value 'simple' in the configuration, check your git version.

After upgrading Xcode (on a Mac running Mountain Lion), which also upgraded git from 1.7.4.4 to 1.8.3.4, shells started before the upgrade were still running git 1.7.4.4 and complained about the value 'simple' for push.default in the global config.

The solution was to close the shells running the old version of git and use the new version.

Use your browser's network inspector (F12) to see when the browser is requesting the bgbody.png image and what absolute path it's using and why the server is returning a 404 response.

...assuming that bgbody.png actually exists :)

Is your CSS in a stylesheet file or in a <style> block in a page? If it's in a stylesheet then the relative path must be relative to the CSS stylesheet (not the document that references it). If it's in a page then it must be relative to the current resource path. If you're using non-filesystem-based resource paths (i.e. using URL rewriting or URL routing) then this will cause problems and it's best to always use absolute paths.

Going by your relative path it looks like you store your images separately from your stylesheets. I don't think this is a good idea - I support storing images and other resources, like fonts, in the same directory as the stylesheet itself, as it simplifies paths and is also a more logical filesystem arrangement.

If you've copied a disk (vmdk file) from one machine to another and need to change a disk's UUID in the copy, you don't need to change the Machine UUID as has been suggested by another answer.

All you need to do is to assign a new UUID to the disk image:

VBoxManage internalcommands sethduuid your-box-disk2.vmdk
UUID changed to: 5d34479f-5597-4b78-a1fa-94e200d16bbb

and then replace the old UUID with the newly generated one in two places in your *.vbox file

<MediaRegistry>
  <HardDisks>
    <HardDisk uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}" location="box-disk2.vmdk" format="VMDK" type="Normal"/>
  </HardDisks>

and in

    <AttachedDevice type="HardDisk" hotpluggable="false" port="0" device="0">
      <Image uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}"/>
    </AttachedDevice>

It worked for me for VirtualBox ver. 5.1.8 running on Mac OS X El Capitan.

A compiler, in general, reads higher level language computer code and converts it to either p-code or native machine code. An interpreter runs directly from p-code or an interpreted code such as Basic or Lisp. Typically, compiled code runs much faster, is more compact, and has already found all of the syntax errors and many of the illegal reference errors. Interpreted code only finds such errors after the application attempts to interpret the affected code. Interpreted code is often good for simple applications that will only be used once or at most a couple times, or maybe even for prototyping. Compiled code is better for serious applications. A compiler first takes in the entire program, checks for errors, compiles it and then executes it. Whereas, an interpreter does this line by line, so it takes one line, checks it for errors, and then executes it.

If you need more information, just Google for "difference between compiler and interpreter".

$(document).ready(function() {
    $('select#select_2').change(function() {
        var selectedText = $(this).find('option:selected').text();
        alert(selectedText);
    });
});

Fiddle

This will ignore the whitespace as well so, your never got the Blank textNodes..code using core Javascript.

var oDiv = document.getElementById("MyDiv");
var firstText = "";
for (var i = 0; i < oDiv.childNodes.length; i++) {
    var curNode = oDiv.childNodes[i];
    whitespace = /^\s*$/;
    if (curNode.nodeName === "#text" && !(whitespace.test(curNode.nodeValue))) {
        firstText = curNode.nodeValue;
        break;
    }
}

Before looking at the difference between java.lang.RuntimeException and java.lang.Exception classes, you must know the Exception hierarchy. Both Exception and Error classes are derived from class Throwable (which derives from the class Object). And the class RuntimeException is derived from class Exception.

All the exceptions are derived either from Exception or RuntimeException.

All the exceptions which derive from RuntimeException are referred to as unchecked exceptions. And all the other exceptions are checked exceptions. A checked exception must be caught somewhere in your code, otherwise, it will not compile. That is why they are called checked exceptions. On the other hand, with unchecked exceptions, the calling method is under no obligation to handle or declare it.

Therefore all the exceptions which compiler forces you to handle are directly derived from java.lang.Exception and all the other which compiler does not force you to handle are derived from java.lang.RuntimeException.

Following are some of the direct known subclasses of RuntimeException.

AnnotationTypeMismatchException,
ArithmeticException,
ArrayStoreException,
BufferOverflowException,
BufferUnderflowException,
CannotRedoException,
CannotUndoException,
ClassCastException,
CMMException,
ConcurrentModificationException,

It is a Child Selector.

It matches when an element is the child of some element. It is made up of two or more selectors separated by ">".

Example(s):

The following rule sets the style of all P elements that are children of BODY:

body > P { line-height: 1.3 }

Example(s):

The following example combines descendant selectors and child selectors:

div ol>li p

It matches a P element that is a descendant of an LI; the LI element must be the child of an OL element; the OL element must be a descendant of a DIV. Notice that the optional white space around the ">" combinator has been left out.

It's just as easy as the following:

AND> if+if

if "%VAR1%"=="VALUE" if "%VAR2%"=="VALUE" *do something*

OR> if // if

set BOTH=0
if "%VAR1%"=="VALUE" if "%VAR2%"=="VALUE" set BOTH=1
if "%BOTH%"=="0" if "%VAR1%"=="VALUE" *do something*
if "%BOTH%"=="0" if "%VAR2%"=="VALUE" *do something*

I know that there are other answers, but I think that the mine is more simple, so more easy to understand. Hope this helps you! ;)

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

This was driving me bonkers as the .astype() solution above didn't work for me. But I found another way. Haven't timed it or anything, but might work for others out there:

t1 = pd.to_datetime('1/1/2015 01:00')
t2 = pd.to_datetime('1/1/2015 03:30')

print pd.Timedelta(t2 - t1).seconds / 3600.0

...if you want hours. Or:

print pd.Timedelta(t2 - t1).seconds / 60.0

...if you want minutes.

Does someone know how I can use a String constant or String[] constant to supply value to an annotation?

Unfortunately, you can't do this with arrays. With non-array variables, the value must be final static.

1. Add injectable decorator to component2(or any component which have the method)

@Injectable({
    providedIn: 'root'
})

2. Inject into component1 (the component from where component2 method will be called)

constructor(public comp2 : component2) { }

3. Define method in component1 from where component2 method is called

method1()
{
    this.comp2.method2();
}

component 1 and component 2 code below.

import {Component2} from './Component2';

@Component({
  selector: 'sel-comp1',
  templateUrl: './comp1.html',
  styleUrls: ['./comp1.scss']
})
export class Component1 implements OnInit {
  show = false;
  constructor(public comp2: Component2) { }
method1()
 {
   this.comp2.method2(); 
  }
}


@Component({
  selector: 'sel-comp2',
  templateUrl: './comp2.html',
  styleUrls: ['./comp2.scss']
})
export class Component2 implements OnInit {
  method2()
{
  alert('called comp2 method from comp1');
}
