Programs & Examples On #Vsto

If you have VS 2013 Express and you cant find Microsoft.Office namespace, try this ('Microsoft Excel 12.0 Object Library' if you want to use Office 2007)

We were receiving the same. The exception was

Stacktrace: at Microsoft.Office.Interop.Excel._Workbook.SaveAs(Object Filename, Object FileFormat, Object Password, Object WriteResPassword, Object ReadOnlyRecommended, Object CreateBackup, XlSaveAsAccessMode AccessMode, Object ConflictResolution, Object AddToMru, Object TextCodepage, Object Text VisualLayout, Object Local)`

with an inner exception of

Exception from HRESULT: 0x800A03EC 2012-11-01 10:37:59`

We were able to resolve the problem with information from this post, which I quote here for convenience...

1. Login to the server as a administrator.
2. Go to "Start" -> "Run" and enter "taskmgr"
3. Go to the process tab in task manager and check "Show Processes from all users"
4. If there are any "Excel.exe" entries on the list, right click on the entry and select "End Process"
5. Close task manager.
6. Go to "Start" -> "Run" and enter "services.msc"
7. Stop the service automating Excel if it is running.
8. Go to "Start" -> "Run" and enter "dcomcnfg"
9. This will bring up the component services window, expand out "Console Root" -> "Computers" -> "DCOM Config"
10. Find "Microsoft Excel Application" in the list of components.
11. Right click on the entry and select "Properties"
12. Go to the "Identity" tab on the properties dialog.
13. Select "The interactive user."
14. Click the "OK" button.
15. Switch to the services console
16. Start the service automating Excel
17. Test you application again.

Here is the code to open an excel sheet using C#.

    Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
    Microsoft.Office.Interop.Excel.Workbook wbv = excel.Workbooks.Open("C:\\YourExcelSheet.xlsx");
    Microsoft.Office.Interop.Excel.Worksheet wx = excel.ActiveSheet as Microsoft.Office.Interop.Excel.Worksheet;

    wbv.Close(true, Type.Missing, Type.Missing);
    excel.Quit();

Here is a video mate on how to open an excel worksheet using C# https://www.youtube.com/watch?v=O5Dnv0tfGv4

I ran to a similar error running Excel in VBA, what I've learned is that when I pull data from MSSQL, and then using get_range and .Value2 apply it's out of the range, any value that was of type uniqueidentifier (GUID) resulted in this error. Only when I cast the value to nvarcahr(max) it worked.

For a VB or C# app, one way to do this is by using Office Interop. This depends on which version of Excel you're working with.

For Excel 2003, this MSDN article is a good place to start. Understanding the Excel Object Model from a Visual Studio 2005 Developer's Perspective

You'll basically need to do the following:

• Start the Excel application.
• Open the Excel workbook.
• Retrieve the worksheet from the workbook by name or index.
• Iterate through all the Cells in the worksheet which were retrieved as a range.
• Sample (untested) code excerpt below for the last step.

    Excel.Range allCellsRng;
    string lowerRightCell = "IV65536";
    allCellsRng = ws.get_Range("A1", lowerRightCell).Cells;
    foreach (Range cell in allCellsRng)
    {
        if (null == cell.Value2 || isBlank(cell.Value2))
        {
          // Do something.
        }
        else if (isText(cell.Value2))
        {
          // Do something.
        }
        else if (isNumeric(cell.Value2))
        {
          // Do something.
        }
    }

For Excel 2007, try this MSDN reference.

Make sure you commit .pfx files to repository.

I just found *.pfx in my default .gitignore. Comment it (by #) and commit changes. Then pull repository and rebuild.

Facing the same problem I found the quickest solution was to actually scan the rows of the cells I wished to sort, determine the last row with a non-blank element and then select and sort on that grouping.

    Dim lastrow As Integer
lastrow = 0
For r = 3 To 120
   If Cells(r, 2) = "" Then
        Dim rng As Range
        Set rng = Range(Cells(3, 2), Cells(r - 1, 2 + 6))
        rng.Select
        rng.Sort Key1:=Range("h3"), order1:=xlDescending, Header:=xlGuess, DataOption1:=xlSortNormal
        r = 205
    End If
Next r

fieldset {display:inline} or fieldset {display:inline-block}

If you want to separate two fieldsets vertically, use a single <br/> between them. This is semantically correct and no harder than it has to be.

epoch is an iteration of subset of the samples for training, for example, the gradient descent algorithm in neutral network. A good reference is: http://neuralnetworksanddeeplearning.com/chap1.html

Note that the page has a code for the gradient descent algorithm which uses epoch

def SGD(self, training_data, epochs, mini_batch_size, eta,
        test_data=None):
    """Train the neural network using mini-batch stochastic
    gradient descent.  The "training_data" is a list of tuples
    "(x, y)" representing the training inputs and the desired
    outputs.  The other non-optional parameters are
    self-explanatory.  If "test_data" is provided then the
    network will be evaluated against the test data after each
    epoch, and partial progress printed out.  This is useful for
    tracking progress, but slows things down substantially."""
    if test_data: n_test = len(test_data)
    n = len(training_data)
    for j in xrange(epochs):
        random.shuffle(training_data)
        mini_batches = [
            training_data[k:k+mini_batch_size]
            for k in xrange(0, n, mini_batch_size)]
        for mini_batch in mini_batches:
            self.update_mini_batch(mini_batch, eta)
        if test_data:
            print "Epoch {0}: {1} / {2}".format(
                j, self.evaluate(test_data), n_test)
        else:
            print "Epoch {0} complete".format(j)

Look at the code. For each epoch, we randomly generate a subset of the inputs for the gradient descent algorithm. Why epoch is effective is also explained in the page. Please take a look.

You don't.

If you want to extend Person with Student, just do:

public class Student extends Person
{
}

And make sure, when you compile both classes, one can find the other one.

What IDE are you using?

Using @Value is a hack, because it outputs two attributes, e.g.:

<input type="..." Value="foo" value=""/>

You should do this instead:

@Html.TextBox(Html.NameFor(p => p.FirstName).ToString(), "foo")

>>> print(f"{'123':<4}56789")
123 56789

In WebStart and the new 6u10 PlugIn you can use the FileOpenService, even without security permissions. For obvious reasons, you only get the file contents, not the file path.

  $this->db->like('title', 'match', 'before'); 
 // Produces: WHERE title LIKE '%match' 

 $this->db->like('title', 'match', 'after'); 
// Produces: WHERE title LIKE 'match%' 

$this->db->like('title', 'match', 'both'); 
// Produces: WHERE title LIKE '%match%'

function routeToRoom(userId, passw, cb) {
    var roomId = 0;
    var nStore = require('nstore/lib/nstore').extend(require('nstore/lib/nstore/query')());
    var users = nStore.new('data/users.db', function() {
        users.find({
            user: userId,
            pass: passw
        }, function(err, results) {
            if (err) {
                roomId = -1;
            } else {
                roomId = results.creationix.room;
            }
            cb(roomId);
        });
    });
}
routeToRoom("alex", "123", function(id) {
    console.log(id);    
});

You need to use callbacks. That's how asynchronous IO works. Btw sys.puts is deprecated

I wrote a simple test for all the above.

def eq(a, b)
  puts "#{[a, '==',  b]} : #{a == b}"
  puts "#{[a, '===', b]} : #{a === b}"
  puts "#{[a, '.eql?', b]} : #{a.eql?(b)}"
  puts "#{[a, '.equal?', b]} : #{a.equal?(b)}"
end

eq("all", "all")
eq(:all, :all)
eq(Object.new, Object.new)
eq(3, 3)
eq(1, 1.0)

statmodels graphics also gives a nice view of correlation matrix

import statsmodels.api as sm
import matplotlib.pyplot as plt

corr = dataframe.corr()
sm.graphics.plot_corr(corr, xnames=list(corr.columns))
plt.show()

MAY BE INTERESTING TO YOU:

In java, string objects are immutable. Immutable simply means unmodifiable or unchangeable.

Once string object is created its data or state can't be changed but a new string object is created.

See sys.exit. That function will quit your program with the given exit status.

C# supports two boolean or operators: the single bar | and the double-bar ||.

The difference is that | always checks both the left and right conditions, while || only checks the right-side condition if it's necessary (if the left side evaluates to false).

This is significant when the condition on the right-side involves processing or results in side effects. (For example, if your ErrorDumpWriter.Close method took a while to complete or changed something's state.)

Yet another way, perhaps the shortest to get status of a single or matched set of tables:

SHOW TABLE STATUS LIKE 'table';

You can then use LIKE operators for example:

SHOW TABLE STATUS LIKE 'field_data_%';

e = ''
while e == '':
    try:
        response = ur.urlopen('https://https://raw.githubusercontent.com/MrMe42/Joe-Bot-Home-Assistant/mac/Joe.py')
        e = ' '
    except:
        print('Connection refused. Retrying...')
        time.sleep(1)

This should work. It sets e to '' and the while loop checks to see if it is still ''. If there is an error caught be the try statement, it prints that the connection was refused, waits 1 second and then starts over. It will keep going until there is no error in try, which then sets e to ' ', which kills the while loop.

This function compares two arrays of arbitrary shape and dimesionality:

function equals(a1, a2) {

    if (!Array.isArray(a1) || !Array.isArray(a2)) {
        throw new Error("Arguments to function equals(a1, a2) must be arrays.");
    }

    if (a1.length !== a2.length) {
        return false;
    }

    for (var i=0; i<a1.length; i++) {
        if (Array.isArray(a1[i]) && Array.isArray(a2[i])) {
            if (equals(a1[i], a2[i])) {
                continue;
            } else {
                return false;
            }
        } else {
            if (a1[i] !== a2[i]) {
                return false;
            }
        }
    }

    return true;
}

Using Date pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z' and Java 8 you could do

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);

Update: For pre 26 use Joda time

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
LocalDate date = org.joda.time.LocalDate.parse(string, formatter);

In app/build.gradle file, add like this-

dependencies {    
    compile 'joda-time:joda-time:2.9.4'
}

Even if this question has resolved, I want to add my advice about that.... since as developer I ignored.

Is important to know that we're talking about MSSQL xp_cmdshell enabled is critical to security, as indicated in the message warning:

Blockquote SQL Server blocked access to procedure 'sys.xp_cmdshell' of component 'xp_cmdshell' because this component is turned off as part of the security configuration for this server. [...]

Leaving the service enabled is a kind of weakness, that for example in a web-app could reflect and execute commands SQL from an attacker. The popular CWE-89: SQL Injection it could be weakness in the our software, and therefore these type of scenarios could pave the way to possible attacks, such as CAPEC-108: Command Line Execution through SQL Injection

I hope to have done something pleasant, we Developers and Engineer do things with awareness and we will be safer!

set ansi_nulls off go select * from table t inner join otherTable o on t.statusid = o.statusid go set ansi_nulls on go

To avoid calling .getName() twice I would use

name = city.getName();
if (name == null) name = "N/A";

One solution is to style the left border like so:

li { display: inline; }
li + li {
  border-left: 1px solid;
  margin-left:.5em;
  padding-left:.5em;
}

However, this may not give you desirable results if the entire lists wraps, like it does in your example. I.e. it would give something like:

foo | bar | baz
 | bob | bill
 | judy

There is a bunch on here:

http://www.webservicex.net/WS/wscatlist.aspx

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.

Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.

I see a lot of answers here that have you subtracting from the width of the div and/or using box-sizing, but all you need to do is apply the padding the child elements of the div in question. So, for example, if you have some markup like this:

<div id="container">
    <p id="text">Find Agents</p>
</div>

All you need to do is apply this CSS:

#text {
    padding: 10px;
}

Here is a fiddle showing the difference: http://jsfiddle.net/CHCVF/2/

Or, better yet, if you have multiple elements and don't feel like giving them all the same class, you can do something like this:

.container * {
    padding: 5px 10px;
}

Which will select all of the child elements and assign them the padding you want. Here is a fiddle of that in action: http://jsfiddle.net/CHCVF/3/

I was also looking for the global .gitconfig on my Windows machine and found this neat trick using git.

Do a: git config --global -e and then, if you are lucky, you will get a text editor loaded with your global .gitconfig file. Simply lookup the folder from there (or try a save as...), et voilà! :-)

Final working solution using @Arrigo response and @Samitha Chathuranga comment, I'll put all together to build a full response for this question:

1. Suppose you have your project folder on PC;

2. Create a new repository on bitbucket:

3. Press on I have an existing project:

4. Open Git CMD console and type command 1 from second picture(go to your project folder on your PC)

5. Type command git init

6. Type command git add --all

7. Type command 2 from second picture (git remote add origin YOUR_LINK_TO_REPO)

8. Type command git commit -m "my first commit"

9. Type command git push -u origin master

Note: if you get error unable to detect email or name, just type following commands after 5th step:

 git config --global user.email "yourEmail"  #your email at Bitbucket
 git config --global user.name "yourName"  #your name at Bitbucket

Try to use a

• $(window).load event

or

• $(document).ready

  because the initial values may be inconstant because of changes that occur during the parsing or during the DOM load.

Use CURRENT_TIMESTAMP (or GETDATE() on archaic versions of SQL Server).

This isn't on the code parter it's on the server side Contact your Server Manager or fix it from server if you own it If you use CPANEL/WHM GO TO WHM/SMTP RESTRICTIONS AND DISABLE IT

Try this query:

SELECT column_name
  FROM table_name
 GROUP BY column_name
HAVING COUNT(column_name) = 1;

Flexbox is a modern alternative that lets you do this without fixed heights or JavaScript.

Setting display: flex; flex-direction: column; on the container and flex-shrink: 0; on the header and footer divs does the trick:

You need to set up your tracking (upstream) for the current branch

git branch --set-upstream master origin/master

Is already deprecated instead of that you can use --track flag

git branch --track master origin/master

I also like the doc reference that @casey notice:

-u <upstream>
  Set up <branchname>'s tracking information so <upstream> is considered  
  <branchname>'s upstream branch. If no <branchname> is specified,  
  then it defaults to the current branch.

This woked for me.

file_browse_path=C:\Users\Gunjan\Desktop\New folder\100x25Barcode.prn
  String path = @"" + file_browse_path.Text;

  if (!File.Exists(path))
             {
      MessageBox.Show("File not exits. Please enter valid path for the file.");
                return;
             }

Following query also can be used:

select * 
  from t23
 where trunc(start_date) between trunc(to_date('01/15/2010','mm/dd/yyyy')) and trunc(to_date('01/17/2010','mm/dd/yyyy'))

PerformSelector:WithObject always takes an object, so in order to pass arguments like int/double/float etc..... You can use something like this.

//NSNumber is an object..

[self performSelector:@selector(setUserAlphaNumber:)
     withObject: [NSNumber numberWithFloat: 1.0f]       
     afterDelay:1.5];



-(void) setUserAlphaNumber: (NSNumber*) number{

     [txtUsername setAlpha: [number floatValue] ];

}

Same way you can use [NSNumber numberWithInt:] etc.... and in the receiving method you can convert the number into your format as [number int] or [number double].

http://momentjs.com/docs/#/displaying/unix-timestamp/

You get the number of unix seconds, not milliseconds!

You you need to multiply it with 1000 or using valueOf() and don't forget to use a formatter, since you are using a non ISO 8601 format. And if you forget to pass the formatter, the date will be parsed in the UTC timezone or as an invalid date.

moment("10/15/2014 9:00", "MM/DD/YYYY HH:mm").valueOf()

// Sorted
let Sorted = Object.entries({ "a":4, "b":0.5 , "c":0.35, "d":5 }).sort((prev, next) => prev[1] - next[1])
>> [ [ 'c', 0.35 ], [ 'b', 0.5 ], [ 'a', 4 ], [ 'd', 5 ] ]


//Min:
Sorted.shift()
>> [ 'c', 0.35 ]

// Max:
Sorted.pop()
>> [ 'd', 5 ]

A major practical difference is its use:

in security scenario where we always needed a new session, we should use request.getSession(true).

request.getSession(false): will return null if no session found.

If you want to use Unix shell commands on Windows, you can use Windows Powershell, which includes both Windows and Unix commands as aliases. You can find more info on it in the documentation.

PowerShell supports aliases to refer to commands by alternate names. Aliasing allows users with experience in other shells to use common command names that they already know for similar operations in PowerShell.

The PowerShell equivalents may not produce identical results. However, the results are close enough that users can do work without knowing the PowerShell command name.

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

Per JamieL's answer to another post:

Since Express.js 3x the response object has a json() method which sets all the headers correctly for you.

Example:

res.json({"foo": "bar"});

It has nothing to do with jQuery, it's just a handy js method built into modern browsers.

Think of it as a handy alternative to debugging via window.alert()

Your code is indeed using the normal way to create and delete a dynamic object. Yes, it's perfectly normal (and indeed guaranteed by the language standard!) that delete will call the object's destructor, just like new has to invoke the constructor.

If you weren't instantiating Object1 directly but some subclass thereof, I'd remind you that any class intended to be inherited from must have a virtual destructor (so that the correct subclass's destructor can be invoked in cases analogous to this one) -- but if your sample code is indeed representative of your actual code, this cannot be your current problem -- must be something else, maybe in the destructor code you're not showing us, or some heap-corruption in the code you're not showing within that function or the ones it calls...?

BTW, if you're always going to delete the object just before you exit the function which instantiates it, there's no point in making that object dynamic -- just declare it as a local (storage class auto, as is the default) variable of said function!

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

A big difference is that ConstraintLayout respects constraints even if the view is gone. So it won't break the layout if you have a chain and you want to make a view disappear in the middle.

This works for me:

<project>
  ...
  <profiles>
    <profile>
      <id>qa</id>
      <build>
        <plugins>

            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
              <execution>
                <phase>install</phase>
                <goals>
                  <goal>copy-dependencies</goal>
                </goals>
                <configuration>
                  <outputDirectory>${project.build.directory}/lib</outputDirectory>
                </configuration>
              </execution>
            </executions>
          </plugin>
        </plugins>
      </build>
    </profile>
  </profiles>
</project>

This solution should work for IE9 and up.

It's like jQuery's parents() method when you need to get a parent container which might be up a few levels from the given element, like finding the containing <form> of a clicked <button>. Looks through the parents until the matching selector is found, or until it reaches the <body>. Returns either the matching element or the <body>.

function parents(el, selector){
    var parent_container = el;
    do {
        parent_container = parent_container.parentNode;
    }
    while( !parent_container.matches(selector) && parent_container !== document.body );

    return parent_container;
}

A little thing I put together

domready.js

(function(exports, d) {
  function domReady(fn, context) {

    function onReady(event) {
      d.removeEventListener("DOMContentLoaded", onReady);
      fn.call(context || exports, event);
    }

    function onReadyIe(event) {
      if (d.readyState === "complete") {
        d.detachEvent("onreadystatechange", onReadyIe);
        fn.call(context || exports, event);
      }
    }

    d.addEventListener && d.addEventListener("DOMContentLoaded", onReady) ||
    d.attachEvent      && d.attachEvent("onreadystatechange", onReadyIe);
  }

  exports.domReady = domReady;
})(window, document);

How to use it

<script src="domready.js"></script>
<script>
  domReady(function(event) {
    alert("dom is ready!");
  });
</script>

You can also change the context in which the callback runs by passing a second argument

function init(event) {
  alert("check the console");
  this.log(event);
}

domReady(init, console);

What you want is this overload :

//linkText, actionName, controllerName, routeValues, htmlAttributes
<%=Html.ActionLink("Details", "Details", 
    "Product", new {id = item.ID}, null) %>

The best way to do it is to add this in your build.gradle file and hit the sync option

dependency{
    compile files('path.jar')
}

Instead ofnull, use CustomerDTO customers =new CustomerDTO()`;

CustomerDTO customer = null;


  private static List<Author> getAllAuthors() {
    initConnection();
    List<Author> authors = new ArrayList<Author>();
    Author author = new Author();
    try {
        stmt = (Statement) conn.createStatement();
        String str = "SELECT * FROM author";
        rs = (ResultSet) stmt.executeQuery(str);

        while (rs.next()) {
            int id = rs.getInt("nAuthorId");
            String name = rs.getString("cAuthorName");
            author.setnAuthorId(id);
            author.setcAuthorName(name);
            authors.add(author);
            System.out.println(author.getnAuthorId() + " - " + author.getcAuthorName());
        }
        rs.close();
        closeConnection();
    } catch (Exception e) {
        System.out.println(e);
    }
    return authors;
}

Put your prompt in the 1st option and disable it:

<selection>
    <option disabled selected>”Select a language”</option>
    <option>English</option>
    <option>Spanish</option>
</selection>

The first option will automatically be the selected default (what you see first when you look at the drop-down) but adding the selected attribute is more clear and actually needed when the first field is a disabled field.

The disabled attribute will make the option be un-selectable/grayed out.

Other answers suggest setting disabled=“disabled” but that’s only necessary if you need to parse as XHTML, which is basically a more strict version of HTML. disabled on it’s on is enough for standard HTML.

If you want to make the selection “required” (without accepting the “Select a language” option as an accepted answer):

Add the required attribute to selection and set the first option’s value to the empty string ””.

<selection required>
    <option disabled value=“”>Select a language</option>
    <option>English</option>
    <option>Spanish</option>
</selection>

There are two problems with your attempt.

First, you've used n+1 instead of i+1, so you're going to return something like [5, 5, 5, 5] instead of [1, 2, 3, 4].

Second, you can't for-loop over a number like n, you need to loop over some kind of sequence, like range(n).

So:

def naturalNumbers(n):
    return [i+1 for i in range(n)]

But if you already have the range function, you don't need this at all; you can just return range(1, n+1), as arshaji showed.

So, how would you build this yourself? You don't have a sequence to loop over, so instead of for, you have to build it yourself with while:

def naturalNumbers(n):
    results = []
    i = 1
    while i <= n:
        results.append(i)
        i += 1
    return results

Of course in real-life code, you should always use for with a range, instead of doing things manually. In fact, even for this exercise, it might be better to write your own range function first, just to use it for naturalNumbers. (It's already pretty close.)

There is one more option, if you want to get clever.

If you have a list, you can slice it. For example, the first 5 elements of my_list are my_list[:5]. So, if you had an infinitely-long list starting with 1, that would be easy. Unfortunately, you can't have an infinitely-long list… but you can have an iterator that simulates one very easily, either by using count or by writing your own 2-liner equivalent. And, while you can't slice an iterator, you can do the equivalent with islice. So:

from itertools import count, islice
def naturalNumbers(n):
    return list(islice(count(1), n))

You need to define a new type and define your function to return that type.

CREATE TYPE my_type AS (f1 varchar(10), f2 varchar(10) /* , ... */ );

CREATE OR REPLACE FUNCTION get_object_fields(name text) 
RETURNS my_type 
AS 
$$

DECLARE
  result_record my_type;

BEGIN
  SELECT f1, f2, f3
  INTO result_record.f1, result_record.f2, result_record.f3
  FROM table1
  WHERE pk_col = 42;

  SELECT f3 
  INTO result_record.f3
  FROM table2
  WHERE pk_col = 24;

  RETURN result_record;

END
$$ LANGUAGE plpgsql; 

If you want to return more than one record you need to define the function as returns setof my_type

Update

Another option is to use RETURNS TABLE() instead of creating a TYPE which was introduced in Postgres 8.4

CREATE OR REPLACE FUNCTION get_object_fields(name text) 
  RETURNS TABLE (f1 varchar(10), f2 varchar(10) /* , ... */ )
...

Tuples are immutable and not supposed to be changed - that is what the list type is for. You could replace each tuple by originalTuple + (newElement,), thus creating a new tuple. For example:

t = (1,2,3)
t = t + (1,)
print t
(1,2,3,1)

But I'd rather suggest to go with lists from the beginning, because they are faster for inserting items.

And another hint: Do not overwrite the built-in name list in your program, rather call the variable l or some other name. If you overwrite the built-in name, you can't use it anymore in the current scope.

In my case, I solved adding return in the onClientClick:

Code Behind

function verify(){
  if (document.getElementById("idName").checked == "") {
    alert("Fill the field");
    return false;
  }
}

Design Surface

<asp:Button runat="server" ID="send" Text="Send" onClientClick="return verify()" />

For Unix users, mail() is actually using Sendmail command to send email. Instead of modifying the application, you can change the environment. msmtp is an SMTP client with Sendmail compatible CLI syntax which means it can be used in place of Sendmail. It only requires a small change to your php.ini.

sendmail_path = "/usr/bin/msmtp -C /path/to/your/config -t"

Then even the lowly mail() function can work with SMTP goodness. It is super useful if you're trying to connect an existing application to mail services like sendgrid or mandrill without modifying the application.

Try this:

I bought (.* )?sheep

or even

I bought .*sheep

How about set the Collision Detection of rigidbody to Continuous or Continuous Dynamic?

http://unity3d.com/support/documentation/Components/class-Rigidbody.html

In addition to what mentioned before, you can use [attr.selected] directive to select a specific option, as follows:

<select>
    <option *ngFor="let program of programs" [attr.selected]="(member.programID == program.id)">
        {{ program.name }}
    </option>
</select>

Well, it's JavaScript, so what you have in 'value' is a Number, which can be an integer or a float. But there's not really a difference in JavaScript. From Learning JavaScript:

The Number Data Type

Number data types in JavaScript are floating-point numbers, but they may or may not have a fractional component. If they don’t have a decimal point or fractional component, they’re treated as integers—base-10 whole numbers in a range of –2⁵³ to 2⁵³.

Just change database name from web.config project level file and then update database.

connectionString = Data Source =(LocalDb)\MSSQLLocalDB;AttachDbFilename="|DataDirectory|\aspnet-Project name-20180413070506.mdf";Initial Catalog="aspnet--20180413070506";Integrated

Change the bold digit to some other number:

connectionString = Data Source==(LocalDb)\MSSQLLocalDB;AttachDbFilename="|DataDirectory|\aspnet-Project name-20180413070507.mdf";Initial Catalog="aspnet--20180413070507";Integrated

AWS Lambda/API Gateway

For information on how to configure multiple origins on Serverless AWS Lambda and API Gateway - albeit a rather large solution for something one would feel should be quite straightforward - see here:

https://stackoverflow.com/a/41708323/1624933

It is currently not possible to configure multiple origins in API Gateway, see here: https://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-cors-console.html), but the recommendation (in the answer above) is:

• inspect the Origin header sent by the browser
• check it against a whitelist of origins
• if it matches, return the incoming Origin as the Access-Control-Allow-Origin header, else return a placeholder (default origin).

The simple solution is obviously enabling ALL (*) like so:

exports.handler = async (event) => {
    const response = {
        statusCode: 200,
        headers: {
            "Access-Control-Allow-Origin": "*",
            "Access-Control-Allow-Credentials" : true // Required for cookies, authorization headers with HTTPS
        },
        body: JSON.stringify([{

But it might be better to do this on the API Gateway side (see 2nd link above).

We use Slick Grid in Stack Exchange Data Explorer (example containing 2000 rows).

I found it outperforms jqGrid and flexigrid. It has a very complete feature set and I could not recommend it enough.

Samples of its usage are here.

You can see source samples on how it is integrated to an ASP.NET MVC app here: https://code.google.com/p/stack-exchange-data-explorer/

No need for an init() function, std::vector can be created from a range:

// h file:
class MyClass {
    static std::vector<char> alphabet;
// ...
};

// cpp file:
#include <boost/range.hpp>
static const char alphabet[] = "abcdefghijklmnopqrstuvwxyz";
std::vector<char> MyClass::alphabet( boost::begin( ::alphabet ), boost::end( ::alphabet ) );

Note, however, that statics of class type cause trouble in libraries, so they should be avoided there.

C++11 Update

As of C++11, you can do this instead:

// cpp file:
std::vector<char> MyClass::alphabet = { 'a', 'b', 'c', ..., 'z' };

It's semantically equivalent to the C++98 solution in the original answer, but you can't use a string literal on the right-hand-side, so it's not completely superior. However, if you have a vector of any other type than char, wchar_t, char16_t or char32_t (arrays of which can be written as string literals), the C++11 version will strictly remove boilerplate code without introducing other syntax, compared to the C++98 version.

Use the CSS white-space property instead of opening yourself up to XSS vulnerabilities!

<span style="white-space: pre-line">@Model.CommentText</span>

For Windows 8:

Control Panel -> (Search for) Credentials Manager -> Check Web Credentials

this worked for me...

if you want to check if your passed string is in string then there is a simple method for that.

string yourStringForCheck= "abc";
string stringInWhichWeCheck= "Test abc abc";

bool isContained = stringInWhichWeCheck.ToLower().IndexOf(yourStringForCheck.ToLower()) > -1;

This boolean value will return if the string is contained or not

You can use these to factor out code common to all tests in the test suite.

If you have a lot of repeated code in your tests, you can make them shorter by moving this code to setUp/tearDown.

You might use this for creating test data (e.g. setting up fakes/mocks), or stubbing out functions with fakes.

If you're doing integration testing, you can use check environmental pre-conditions in setUp, and skip the test if something isn't set up properly.

For example:

class TurretTest(unittest.TestCase):

    def setUp(self):
        self.turret_factory = TurretFactory()
        self.turret = self.turret_factory.CreateTurret()

    def test_turret_is_on_by_default(self):
        self.assertEquals(True, self.turret.is_on())

    def test_turret_turns_can_be_turned_off(self):
        self.turret.turn_off()
        self.assertEquals(False, self.turret.is_on())

For this kind of folder structure:

main.go
mylib/
  mylib.go

The simplest way is to use this:

import (
    "./mylib"
)

If used inside Bootstrap v3 tabs, the following should work:

$('a[href="#tab-location"]').on('shown.bs.tab', function(e){
    var center = map.getCenter();
    google.maps.event.trigger(map, 'resize');
    map.setCenter(center);
});

where tab-location is the ID of tab containing map.

jQuery has few functions which work with text, if you use text() one, it will do the job for you:

$("#regTitle").text("Hello World");

Also, you can use html() instead, if you have any html tag...

It sounds like your printMousePos function should:

1. Get the X and Y coordinates of the mouse
2. Add those values to the HTML

Currently, it does this:

1. Creates (undefined) variables for the X and Y coordinates of the mouse
2. Attaches a function to the "mousemove" event (which will set those variables to the mouse coordinates when triggered by a mouse move)
3. Adds the current values of your variables to the HTML

See the problem? Your variables are never getting set, because as soon as you add your function to the "mousemove" event you print them.

It seems like you probably don't need that mousemove event at all; I would try something like this:

function printMousePos(e) {
    var cursorX = e.pageX;
    var cursorY = e.pageY;
    document.getElementById('test').innerHTML = "x: " + cursorX + ", y: " + cursorY;
}

This can also be done in later versions of handlebars using the key=value notation:

 {{> mypartial foo='bar' }}

Allowing you to pass specific values to your partial context.

Reference: Context different for partial #182

set myDIR=LOG
IF not exist %myDIR% (mkdir %myDIR%)

Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.

Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.

The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error

Easiest way: change the Windows Display Properties main window background color. I went to Appearance tab, changed to Silver scheme, clicked Advanced, clicked on "Active Window" and changed Color 1 to a light gray. All Eclipse views softened.

Since Luna (4.4) there seems to be a full Dark them in

Window -> Preferences -> General -> Appearance -> Theme -> Dark

You may be able to fix this error by name spacing :: the function call

comparison.cloud(colors = c("red", "green"), max.words = 100)

to

wordcloud::comparison.cloud(colors = c("red", "green"), max.words = 100)

I bought a theme from www.xamltemplates.net. The themes ship with source code so you can tweak them. They also offer a free theme (source code included).

You can index into a tuple:

(falseValue, trueValue)[test]

test needs to return True or False.
It might be safer to always implement it as:

(falseValue, trueValue)[test == True]

or you can use the built-in bool() to assure a Boolean value:

(falseValue, trueValue)[bool(<expression>)]

Another way to compile C# programs (without using Visual Studio or without having it installed) is to create a user variable in environment variables, namely "PATH".

Copy the following path in this variable:

"C:\Windows\Microsoft.NET\Framework\v4.0.30319"

or depending upon which .NET your PC have.

So you don't have to mention the whole path every time you compile a code. Simply use

"C:\Users\UserName\Desktop>csc [options] filename.cs"

or wherever the path of your code is.

Now you are good to go.

Unfortunately, at the time of writing this answer, there is no direct way to do this. You need to:

1. use a semi-transparent image for background (much easier).
2. add an extra element (like div) next to children which you want the opaque, add background to it and after making it semi-transparent, position it behind mentioned children.

In newer versions of typescript you can use:

type Customers = Record<string, Customer>

In older versions you can use:

var map: { [email: string]: Customer; } = { };
map['[email protected]'] = new Customer(); // OK
map[14] = new Customer(); // Not OK, 14 is not a string
map['[email protected]'] = 'x'; // Not OK, 'x' is not a customer

You can also make an interface if you don't want to type that whole type annotation out every time:

interface StringToCustomerMap {
    [email: string]: Customer;
}

var map: StringToCustomerMap = { };
// Equivalent to first line of above

Use path.join(__dirname, '/start.html');

var fs = require('fs'),
    path = require('path'),    
    filePath = path.join(__dirname, 'start.html');

fs.readFile(filePath, {encoding: 'utf-8'}, function(err,data){
    if (!err) {
        console.log('received data: ' + data);
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.write(data);
        response.end();
    } else {
        console.log(err);
    }
});

Wrap it in a function:

create function now_utc() returns timestamp as $$
  select now() at time zone 'utc';
$$ language sql;

create temporary table test(
  id int,
  ts timestamp without time zone default now_utc()
);

I just had a very similar issue with the added problem that I needed to create download links to files inside a ZIP file.

I first tried to create a temporary file, then provided a link to the temporary file, but I found that some browsers would just display the contents (a CSV Excel file) rather than offering to download. Eventually I found the solution by using a servlet. It works both on Tomcat and GlassFish, and I tried it on Internet Explorer 10 and Chrome.

The servlet takes as input a full path name to the ZIP file, and the name of the file inside the zip that should be downloaded.

Inside my JSP file I have a table displaying all the files inside the zip, with links that say: onclick='download?zip=<%=zip%>&csv=<%=csv%>'

The servlet code is in download.java:

package myServlet;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.zip.*;
import java.util.*;

// Extend HttpServlet class
public class download extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException
    {
        PrintWriter out = response.getWriter(); // now we can write to the client

        String filename = request.getParameter("csv");
        String zipfile = request.getParameter("zip");

        String aLine = "";

        response.setContentType("application/x-download");
        response.setHeader( "Content-Disposition", "attachment; filename=" + filename); // Force 'save-as'
        ZipFile zip = new ZipFile(zipfile);
        for (Enumeration e = zip.entries(); e.hasMoreElements();) {
            ZipEntry entry = (ZipEntry) e.nextElement();
            if(entry.toString().equals(filename)) {
                InputStream is = zip.getInputStream(entry);
                BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"), 65536);
                while ((aLine = br.readLine()) != null) {
                    out.println(aLine);
                }
                is.close();
                break;
            }
        }
    }
}

To compile on Tomcat you need the classpath to include tomcat\lib\servlet-api.jar or on GlassFish: glassfish\lib\j2ee.jar

But either one will work on both. You also need to set your servlet in web.xml.

When you get a UnicodeEncodeError, it means that somewhere in your code you convert directly a byte string to a unicode one. By default in Python 2 it uses ascii encoding, and utf8 encoding in Python3 (both may fail because not every byte is valid in either encoding)

To avoid that, you must use explicit decoding.

If you may have 2 different encoding in your input file, one of them accepts any byte (say UTF8 and Latin1), you can try to first convert a string with first and use the second one if a UnicodeDecodeError occurs.

def robust_decode(bs):
    '''Takes a byte string as param and convert it into a unicode one.
First tries UTF8, and fallback to Latin1 if it fails'''
    cr = None
    try:
        cr = bs.decode('utf8')
    except UnicodeDecodeError:
        cr = bs.decode('latin1')
    return cr

If you do not know original encoding and do not care for non ascii character, you can set the optional errors parameter of the decode method to replace. Any offending byte will be replaced (from the standard library documentation):

Replace with a suitable replacement character; Python will use the official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on decoding and ‘?’ on encoding.

bs.decode(errors='replace')

Not answering the question directly, but it might help someone else.

I have a column called Volume, having both - (invalid/NaN) and numbers formatted with ,

df['Volume'] = df['Volume'].astype('str')
df['Volume'] = df['Volume'].str.replace(',', '')
df['Volume'] = pd.to_numeric(df['Volume'], errors='coerce')

Casting to string is required for it to apply to str.replace

pandas.Series.str.replace
pandas.to_numeric

Just use Control.Invoke Method or Control.BeginInvoke Method.

Great example: How to: Make Thread-Safe Calls to Windows Forms Controls.

$_GET['start_date'] is not numeric is my bet, but an date format not supported by strtotime. You will need to re-format the date to a workable format for strtotime or use combination of explode/mktime.

I could add you an example if you'd be kind enough to post the format you currently receive.

Go to AndroidManifest.xml file. Find the <application> tag There you can see a attribute

android:label="@string/app_name"

Now go to res > values > strings.xml

Change the

<string name="app_name">MainActivity</string> 

to

<string name="app_name">Your Desired Name</string>

Example

AndroidManifest.xml

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".SubmitForm">

        </activity>
    </application>

strings.xml

<resources>
    <string name="app_name">Your Desired Name</string>
    <string name="action_settings">Settings</string>
</resources>

Robby provides a great answer, though I can see you still looking for more information. I implemented REST api calls the easy BUT wrong way. It wasn't until watching this Google I/O video that I understood where I went wrong. It's not as simple as putting together an AsyncTask with a HttpUrlConnection get/put call.

My answer is a total hack- I just created a link that looks like a button and add the URL to that.

<a class="el-button"
  style="color: white; background-color: #58B7FF;"
  :href="<YOUR URL ENDPOINT HERE>"
  :download="<FILE NAME NERE>">
<i class="fa fa-file-excel-o"></i>&nbsp;Excel
</a>

I'm using the excellent VueJs hence the odd anotations, however, this solution is framework agnostic. The idea would work for any HTML based design.

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

I understand that the answer is given but I wrote a simple example to make it easy to understand for beginners like me:

var x = { println("x"); 15 }
lazy val y = { println("y"); x + 1 }
println("-----")
x = 17
println("y is: " + y)

Output of above code is:

x
-----
y
y is: 18

As it can be seen, x is printed when it's initialized, but y is not printed when it's initialized in same way (I have taken x as var intentionally here - to explain when y gets initialized). Next when y is called, it's initialized as well as value of last 'x' is taken into consideration but not the old one.

Hope this helps.

What you really want is logging module from standard library. Create a logger and attach two handlers, one would be writing to a file and the other to stdout or stderr.

See Logging to multiple destinations for details

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

You get that because you're trying to get a key from a dictionary when it's not there. You need to test if it is in there first.

try:

is_private = 'is_private' in request.POST

or

is_private = 'is_private' in request.POST and request.POST['is_private']

depending on the values you're using.

Take a look at http://www.w3schools.com/jsref/jsref_obj_date.asp

There is a function UTC() that returns the milliseconds from the unix epoch.

Method 1 ( for multiserver )

First , lets make a backup of original config.

sudo cp /etc/phpmyadmin/config.inc.php      ~/ 

Now in /usr/share/doc/phpmyadmin/examples/ you will see a file config.manyhosts.inc.php. Just copy in to /etc/phpmyadmin/ using command bellow:

sudo cp /usr/share/doc/phpmyadmin/examples/config.manyhosts.inc.php \
        /etc/phpmyadmin/config.inc.php

Edit the config.inc.php

sudo nano /etc/phpmyadmin/config.inc.php 

Search for :

$hosts = array (
    "foo.example.com",
    "bar.example.com",
    "baz.example.com",
    "quux.example.com",
);

And add your ip or hostname array save ( in nano CTRL+X press Y ) and exit . Done

Method 2 ( single server ) Edit the config.inc.php

sudo nano /etc/phpmyadmin/config.inc.php 

Search for :

/* Server parameters */
if (empty($dbserver)) $dbserver = 'localhost';
$cfg['Servers'][$i]['host'] = $dbserver;

if (!empty($dbport) || $dbserver != 'localhost') {
    $cfg['Servers'][$i]['connect_type'] = 'tcp';
    $cfg['Servers'][$i]['port'] = $dbport;
}

And replace with:

$cfg['Servers'][$i]['host'] = '192.168.1.100';
$cfg['Servers'][$i]['port'] = '3306';

Remeber to replace 192.168.1.100 with your own mysql ip server.

Sorry for my bad English ( google translate have the blame :D )

First of all, you aren't forced to use an SMTP on your localhost, if you change that localhost entry into the DNS name of the MTA from your ISP provider (who will let you relay mail) it will work right away, so no messing about with your own email service. Just try to use your providers SMTP servers, it will work right away.

Select is a transformation, not an action, so it is lazily evaluated (won't actually do the calculations just map the operations). Collect is an action.

Try:

df.limit(20).collect()

db.users.find( { 'username' : { '$regex' : req.body.keyWord, '$options' : 'i' } } )

There are working combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.

Use one of the following combinations.

• 32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)
• 64-bit OS, 32-bit JDK, 32-bit Eclipse
• 64-bit OS, 64-bit JDK, 64-bit Eclipse (64-bit only)

p {
    float: left;
    margin: 0;

No spacing will be around, it looks similar to span.

On my network just setting http_proxy didn't work for me. The following points were relevant.

1 Setting http_proxy for your user wont be preserved when you execute sudo - to preserve it, do:

sudo -E yourcommand

I got my install working by first installing cntlm local proxy. The instructions here is succinct : http://www.leg.uct.ac.za/howtos/use-isa-proxies

Instead of student number, you'd put your domain username

2 To use the cntlm local proxy, exec:

pip install --proxy localhost:3128 pygments

I downloaded "Microsoft® System CLR Types for Microsoft® SQL Server® 2012" and "Microsoft® SQL Server® 2012 Shared Management Objects" from @ImanMahmoudinasab mentioned link, but Shared Management Objects had problem while installing and it showed some dependencies message and at the end installation Failed!

Finally I solved the problem with Power Shell. I run PS as administrator with the below command:

Start-Process <path>\SharedManagementObjects.msi

This is quite late but anyone going through the same problem might benefit from this answer.First try to add browser by running below command ionic platform add browser and then run command ionic run browser.

which is the difference between ionic serve and ionic run browser?

Ionic serve - runs your app as a website (meaning it doesn't have any Cordova capabilities). Ionic run browser - runs your app in the Cordova browser platform, which will inject cordova.js and any plugins that have browser capabilities

You can refer this link to know more difference between ionic serve and ionic run browser command

Update

From Ionic 3 this command has been changed. Use the command below instead;

ionic cordova platform add browser

ionic cordova run browser

You can find out which version of ionic you are using by running: ionic --version

Try the following code:

moment(startDate).startOf('months')
moment(startDate).endOf('months')

I was getting this error while posting a FormData object because I was not setting up the ajax call correctly. Setup below fixed my issue.

var myformData = new FormData();        
myformData.append('leadid', $("#leadid").val());
myformData.append('date', $(this).val());
myformData.append('time', $(e.target).prev().val());

$.ajax({
    method: 'post',
    processData: false,
    contentType: false,
    cache: false,
    data: myformData,
    enctype: 'multipart/form-data',
    url: 'include/ajax.php',
    success: function (response) {
        $("#subform").html(response).delay(4000).hide(1); 
    }
});

Expanding upon @aquinas:

Get-something | select -ExpandProperty PropertyName

or

Get-something | select -expand PropertyName

or

Get-something | select -exp PropertyName

I made these suggestions for those that might just be looking for a single-line command to obtain some piece of information and wanted to include a real-world example.

In managing Office 365 via PowerShell, here was an example I used to obtain all of the users/groups that had been added to the "BookInPolicy" list:

Get-CalendarProcessing [email protected] | Select -expand BookInPolicy

Just using "Select BookInPolicy" was cutting off several members, so thank you for this information!

The way to do this to take your nested target array and copy it in single step to a non-nested array. Delete the key(s) and then assign the final trimmed array to the nested node of the earlier array. Here is a code to make it simple:

$temp_array = $list['resultset'][0];

unset($temp_array['badkey1']);
unset($temp_array['badkey2']);

$list['resultset'][0] = $temp_array;

It is always a good practice in your table design to have an automatic row identifier, such as

 [RowID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL

, then you can identify your last row by

 select * from yourTable where rowID =  @@IDENTITY 

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes 

does not work?

Consider using django-bulk-update found here on GitHub.

Install: pip install django-bulk-update

Implement: (code taken directly from projects ReadMe file)

from bulk_update.helper import bulk_update

random_names = ['Walter', 'The Dude', 'Donny', 'Jesus']
people = Person.objects.all()

for person in people:
    r = random.randrange(4)
    person.name = random_names[r]

bulk_update(people)  # updates all columns using the default db

Update: As Marc points out in the comments this is not suitable for updating thousands of rows at once. Though it is suitable for smaller batches 10's to 100's. The size of the batch that is right for you depends on your CPU and query complexity. This tool is more like a wheel barrow than a dump truck.

You could use OPENROWSET, something like:

SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
  'Excel 8.0;IMEX=1;HDR=NO;DATABASE=C:\FILE.xls', 'Select * from [Sheet1$]'

Just make sure the path is a path on the server, not your local machine.

Your problem is with this line:

number4 = list(cow[n])

It tries to take cow[n], which returns an integer, and make it a list. This doesn't work, as demonstrated below:

>>> a = 1
>>> list(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>>

Perhaps you meant to put cow[n] inside a list:

number4 = [cow[n]]

See a demonstration below:

>>> a = 1
>>> [a]
[1]
>>>

Also, I wanted to address two things:

1. Your while-statement is missing a : at the end.
2. It is considered very dangerous to use input like that, since it evaluates its input as real Python code. It would be better here to use raw_input and then convert the input to an integer with int.

To split up the digits and then add them like you want, I would first make the number a string. Then, since strings are iterable, you can use sum:

>>> a = 137
>>> a = str(a)
>>> # This way is more common and preferred
>>> sum(int(x) for x in a)
11
>>> # But this also works
>>> sum(map(int, a))
11
>>>

Matplotlib can handle directly and transparently jpg if you have installed PIL. You don't need to call it, it will do it by itself. If Python cannot find PIL, it will raise an error.

For those who fear to mess anything up in your vscode json settings this is pretty easy to follow.

1. Open "File -> Preferences -> Keyboard Shortcuts" or "Code -> Preferences -> Keyboard Shortcuts" for Mac Users

2. In the search bar type transform.

3. By default you will not have anything under Keybinding. Now double-click on Transform to Lowercase or Transform to Uppercase.

4. Press your desired combination of keys to set your keybinding. In this case if copying off of Sublime i will press ctrl+shift+u for uppercase or ctrl+shift+l for lowercase.

5. Press Enter on your keyboard to save and exit. Do same for the other option.

6. Enjoy KEYBINDING

You could use a javax.swing.ImageIcon and add it to a JLabel using setIcon() method, then add the JLabel to the JPanel.

Try modifying the path in the windows registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment).

Caveat: Don't break the registry :)

TL;DR:

Using slicing:

>>> import numpy as np
>>> 
>>> arr = np.array([[1,2,3,4,5],[6,7,8,9,10]])
>>> 
>>> arr[0,0]
1
>>> arr[1,1]
7
>>> arr[1,0]
6
>>> arr[1,-1]
10
>>> arr[1,-2]
9

In Long:

Hopefully this helps in your understanding:

>>> import numpy as np
>>> np.array([ [1,2,3], [4,5,6] ])
array([[1, 2, 3],
       [4, 5, 6]])
>>> x = np.array([ [1,2,3], [4,5,6] ])
>>> x[1][2] # 2nd row, 3rd column 
6
>>> x[1,2] # Similarly
6

But to appreciate why slicing is useful, in more dimensions:

>>> np.array([ [[1,2,3], [4,5,6]], [[7,8,9],[10,11,12]] ])
array([[[ 1,  2,  3],
        [ 4,  5,  6]],

       [[ 7,  8,  9],
        [10, 11, 12]]])
>>> x = np.array([ [[1,2,3], [4,5,6]], [[7,8,9],[10,11,12]] ])

>>> x[1][0][2] # 2nd matrix, 1st row, 3rd column
9
>>> x[1,0,2] # Similarly
9

>>> x[1][0:2][2] # 2nd matrix, 1st row, 3rd column
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: index 2 is out of bounds for axis 0 with size 2

>>> x[1, 0:2, 2] # 2nd matrix, 1st and 2nd row, 3rd column
array([ 9, 12])

>>> x[1, 0:2, 1:3] # 2nd matrix, 1st and 2nd row, 2nd and 3rd column
array([[ 8,  9],
       [11, 12]])

Try this:

if(Math.floor(id) == id && $.isNumeric(id)) 
  alert('yes its an int!');

$.isNumeric(id) checks whether it's numeric or not
Math.floor(id) == id will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

I am late for the answer but I think this is another solution which is not mentioned here so posting.

Step 1: Make a xml of menu which you want to add like I have to add a filter action on my action bar so I have created a xml filter.xml. The main line to notice is android:orderInCategory this will show the action icon at first or last wherever you want to show. One more thing to note down is the value, if the value is less then it will show at first and if value is greater then it will show at last.

filter.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" >


    <item
        android:id="@+id/action_filter"
        android:title="@string/filter"
        android:orderInCategory="10"
        android:icon="@drawable/filter"
        app:showAsAction="ifRoom" />


</menu>

Step 2: In onCreate() method of fragment just put the below line as mentioned, which is responsible for calling back onCreateOptionsMenu(Menu menu, MenuInflater inflater) method just like in an Activity.

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setHasOptionsMenu(true);
    }

Step 3: Now add the method onCreateOptionsMenu which will be override as:

@Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.filter, menu);  // Use filter.xml from step 1
    }

Step 4: Now add onOptionsItemSelected method by which you can implement logic whatever you want to do when you select the added action icon from actionBar:

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if(id == R.id.action_filter){
            //Do whatever you want to do 
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

protected void grdDis_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            #region Dynamically Show gridView header From data base
            getAllheaderName();/*To get all Allowences master headerName*/

            TextBox txt_Days = (TextBox)grdDis.HeaderRow.FindControl("txtDays");
            txt_Days.Text = hidMonthsDays.Value;
            #endregion
        }
    }

by XML:

 <EditText
        android:id="@+id/search_edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/search"
        android:imeOptions="actionSearch"
        android:inputType="text" />

By Java:

 editText.clearFocus();
    InputMethodManager in = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    in.hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);

It's the same way you run it from command line. Just put that "command line" into a ".bat" file.

So, if you use java -cp .;foo.jar Bar, put that into a .bat file as

@echo off

java -cp .;foo.jar Bar

Got the same problem, non of the answers worked for me. After a lot of debugging I found out that the size of one image was smaller than 32. This leads to a broken array with wrong dimensions and the above mentioned error.

To solve the problem, make sure that all images have the correct dimensions.

$(document).ready(function() {

    $(document)[0].oncontextmenu = function() { return false; }

    $(document).mousedown(function(e) {
        if( e.button == 2 ) {
            alert('Sorry, this functionality is disabled!');
            return false;
        } else {
            return true;
        }
    });
});

If you want to disable it only on image click the instead of $(document).mousedown use $("#yourimage").mousedown

To implement simple SOAP clients in Java, you can use the SAAJ framework (it is shipped with JSE 1.6 and above):

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";

        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String myNamespace = "myNamespace";
        String myNamespaceURI = "http://www.webserviceX.NET";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

            /*
            Constructed SOAP Request Message:

        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetInfoByCity", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("USCity", myNamespace);
        soapBodyElem1.addTextNode("New York");
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();

            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();

        createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", soapAction);

        soapMessage.saveChanges();

        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;
    }

By current official documentation there is a short cut that stops and removes containers, networks, volumes, and images created by up, if they are already stopped or partially removed and so on, then it will do the trick too:

docker-compose down

Then if you have new changes on your images or Dockerfiles use:

docker-compose build --no-cache

Finally:docker-compose up

In one command: docker-compose down && docker-compose build --no-cache && docker-compose up

Store a unique salt for the user (generated from username + email for example), and store a password. On login, get the salt from database and hash salt + password.
Use bcrypt to hash the passwords.

Hello, I've a similar assignment which involved creating a Javascript Countdown Clock. Here's the code I used. Plug the above code between the < script language="Javascript" >< /script > tags. Keep in mind that just having this javascript won't do much if you don't have the html to display the clock. I'll leave writing the html to you. Design the clock however you wish.

To Extend Bill's SQL solution you can basically do the same using a flat array. Further more if your strings all have the same lenght and your maximum number of children are known (say in a binary tree) you can do it using a single string (character array). If you have arbitrary number of children this complicates things a bit... I would have to check my old notes to see what can be done.

Then, sacrificing a bit of memory, especially if your tree is sparse and/or unballanced, you can, with a bit of index math, access all the strings randomly by storing your tree, width first in the array like so (for a binary tree):

String[] nodeArray = [L0root, L1child1, L1child2, L2Child1, L2Child2, L2Child3, L2Child4] ...

yo know your string length, you know it

I'm at work now so cannot spend much time on it but with interest I can fetch a bit of code to do this.

We use to do it to search in binary trees made of DNA codons, a process built the tree, then we flattened it to search text patterns and when found, though index math (revers from above) we get the node back... very fast and efficient, tough our tree rarely had empty nodes, but we could searh gigabytes of data in a jiffy.

Hashmap type Overwrite that key if hashmap key is same key

map.put("1","1111");
map.put("1","2222");

output

key:value
1:2222

Try this:

if ('Hello, World!'.indexOf('orl') !== -1)
    alert("The string 'Hello World' contains the substring 'orl'!");
else
    alert("The string 'Hello World' does not contain the substring 'orl'!");

Here is an example: http://jsfiddle.net/oliverni/cb8xw/

You can also replace "-moz-user-select:none" with "-moz-user-select:inherit". This will inherit the style value from any parent style or from the default style if no parent style was defined.

I came across the same problem but, as stated above, the accepted solution did not work for me.

If you're inside a frame or iframe element, an alternative solution is to use

window.parent.$('#testdiv');

Here's a quick explanation of the differences between window.opener, window.parent and window.top:

• window.opener refers to the window that called window.open( ... ) to open the window from which it's called
• window.parent refers to the parent of a window in a frame or iframe element

you can change color of any text by use html <font> attribute directly in xml files. for example in strings.xml :

<resources>
    <string name = "app_name">
        <html><font color="#001aff">Multi</font></html>
        <html><font color="#ff0044">color</font></html>
        <html><font color="#e9c309">Text </font></html>
    </string>
</resources>

Using an apostrophe ’ (Unicode: \u2019) instead of a single quote ' fixed the issue without doubling the \'.

The shorter ES6 version of the answer:

const delay = t => new Promise(resolve => setTimeout(resolve, t));

And then you can do:

delay(3000).then(() => console.log('Hello'));

If you frequently need to access the Nth element of a sequence, std::list, which is implemented as a doubly linked list, is probably not the right choice. std::vector or std::deque would likely be better.

That said, you can get an iterator to the Nth element using std::advance:

std::list<Object> l;
// add elements to list 'l'...

unsigned N = /* index of the element you want to retrieve */;
if (l.size() > N)
{
    std::list<Object>::iterator it = l.begin();
    std::advance(it, N);
    // 'it' points to the element at index 'N'
}

For a container that doesn't provide random access, like std::list, std::advance calls operator++ on the iterator N times. Alternatively, if your Standard Library implementation provides it, you may call std::next:

if (l.size() > N)
{
    std::list<Object>::iterator it = std::next(l.begin(), N);
}

std::next is effectively wraps a call to std::advance, making it easier to advance an iterator N times with fewer lines of code and fewer mutable variables. std::next was added in C++11.

Maven plugin uses a settings file where the configuration can be set. Its path is available in Eclipse at Window|Preferences|Maven|User Settings. If the file doesn't exist, create it and put on something like this:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">

      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>

</settings>

After editing the file, it's just a matter of clicking on Update Settings button and it's done. I've just done it and it worked :)

I will just add a blank ("") to the end of the variable and do the comparison. Something like below should work even when that variable is null. You can also trim the variable just in case of spaces.

If provider & "" <> "" Then 
    url = url & "&provider=" & provider 
End if

I do not like the echo "..." | awk ... solution as it calls unnecessary fork and execsystem calls.

I prefer a Dimitre's solution with a little twist

awk -F\| '{print $3 $2 $1}' <<<'12|23|11'

Or a bit shorter version:

awk -F\| '$0=$3 $2 $1' <<<'12|23|11'

In this case the output record put together which is a true condition, so it gets printed.

In this specific case the stdin redirection can be spared with setting an awk internal variable:

awk -v T='12|23|11' 'BEGIN{split(T,a,"|");print a[3] a[2] a[1]}'

I used ksh quite a while, but in bash this could be managed by internal string manipulation. In the first case the original string is split by internal terminator. In the second case it is assumed that the string always contains digit pairs separated by a one character separator.

T='12|23|11';echo -n ${T##*|};T=${T%|*};echo ${T#*|}${T%|*}
T='12|23|11';echo ${T:6}${T:3:2}${T:0:2}

The result in all cases is

112312

First the bigint(20) not null auto_increment will not work, simply use bigserial primary key. Then datetime is timestamp in PostgreSQL. All in all:

CREATE TABLE article (
    article_id bigserial primary key,
    article_name varchar(20) NOT NULL,
    article_desc text NOT NULL,
    date_added timestamp default NULL
);

driver.find_element_by_xpath("path").send_keys(Keys.CONTROL + u'\ue003') worked great with FireFox

• u'\ue003' is a BACK_SPACE for those like me - never remembering it)

If you want to use pdf.js, I suggest you to read THIS

You can also upload your pdf somewhere (like Google Drive) and use its URL in a iframe

or

<object data="data/test.pdf" type="application/pdf" width="300" height="200">
<a href="data/test.pdf">test.pdf</a>
</object>

If you want to act on whole browser blur: As I commented, if browser lose focus none of the suggested events fire. My idea is to count up in a loop and reset the counter if an event fire. If the counter reach a limit I do a location.href to an other page. This also fire if you work on dev-tools.

var iput=document.getElementById("hiddenInput");
   ,count=1
   ;
function check(){
         count++;
         if(count%2===0){
           iput.focus();
         }
         else{
           iput.blur();
         }
         iput.value=count;  
         if(count>3){
           location.href="http://Nirwana.com";
         }              
         setTimeout(function(){check()},1000);
}   
iput.onblur=function(){count=1}
iput.onfocus=function(){count=1}
check();

This is a draft successful tested on FF.

std::copy cannot be used to insert into an empty container. To do that, you need to use an insert_iterator like so:

std::set<double> input;
input.insert(5);
input.insert(6);

std::vector<double> output;
std::copy(input.begin(), input.end(), inserter(output, output.begin())); 

$sql = $dbh->prepare("SELECT * from member WHERE member_email = '$username' AND member_password = '$password'");

$sql->execute();

$fetch = $sql->fetch(PDO::FETCH_ASSOC);

// if not empty result
if (is_array($fetch))  {
    $_SESSION["userMember"] = $fetch["username"];
    $_SESSION["password"] = $fetch["password"];
    echo 'yes this member is registered'; 
}else {
    echo 'empty result!';
}

In most cases JOINs are faster than sub-queries and it is very rare for a sub-query to be faster.

In JOINs RDBMS can create an execution plan that is better for your query and can predict what data should be loaded to be processed and save time, unlike the sub-query where it will run all the queries and load all their data to do the processing.

The good thing in sub-queries is that they are more readable than JOINs: that's why most new SQL people prefer them; it is the easy way; but when it comes to performance, JOINS are better in most cases even though they are not hard to read too.

Using a nested .each() means that your inner loop is doing one td at a time, so you can't set the productId and product and quantity all in the inner loop.

Also using function(key, val) and then val[key].innerHTML isn't right: the .each() method passes the index (an integer) and the actual element, so you'd use function(i, element) and then element.innerHTML. Though jQuery also sets this to the element, so you can just say this.innerHTML.

Anyway, here's a way to get it to work:

    table.find('tr').each(function (i, el) {
        var $tds = $(this).find('td'),
            productId = $tds.eq(0).text(),
            product = $tds.eq(1).text(),
            Quantity = $tds.eq(2).text();
        // do something with productId, product, Quantity
    });

I found out one more way: You can check if /usr/local/var/run/nginx.pid exists. If it is - nginx is running. Useful way for scripting.

Example:

if [ -f /usr/local/var/run/nginx.pid ]; then
   echo "Nginx is running"

fi

I think it should be

import webbrowser

webbrowser.open('http://gatedin.com')

NOTE: make sure that you give http or https

if you give "www." instead of "http:" instead of opening a broser the interprete displays boolean OutPut TRUE. here you are importing webbrowser library

The solution I came up with was as follows:

1. Create the SQL query in your favorite query dev tool
2. In Crystal Reports, within the main report, create parameter to pass to the subreport
3. Create sub report, using the 'Add Command' option in the 'Data' portion of the 'Report Creation Wizard' and the SQL query from #1.

4. Once the subreport is added to the main report, right click on the subreport, choose 'Change Subreport Links...', select the link field, and uncheck 'Select data in subreport based on field:'

   NOTE: You may have to initially add the parameter with the 'Select data in subreport based on field:' checked, then go back to 'Change Subreport Links ' and uncheck it after the subreport has been created.

5. In the subreport, click the 'Report' menu, 'Select Expert', use the 'Formula Editor', set the SQL column from #1 either equal to or like the parameter(s) selected in #4.

                   (Subreport SQL Column)  (Parameter from Main Report)
           Example:  {Command.Project} like {?Pm-?Proj_Name}
   

Try this,

window.location.href="sample.html";

Here sample.html is a next page. It will go to the next page.

The width and heigth of a text can be obtained with clientWidth and clientHeight

var element = document.getElementById ("mytext");

var width = element.clientWidth;
var height = element.clientHeight;

make sure that style position property is set to absolute

element.style.position = "absolute";

not required to be inside a div, can be inside a p or a span

AndroidStudio:

Go to: Tools -> Android -> Android Device Monitor

see the Device tab, under many icons, last one is drop-down arrow.

Open it.

At the bottom: RESET ADB.

Here's an example I found on this blog.

$cn2 = new-object system.data.SqlClient.SQLConnection("Data Source=machine1;Integrated Security=SSPI;Initial Catalog=master");
$cmd = new-object system.data.sqlclient.sqlcommand("dbcc freeproccache", $cn2);
$cn2.Open();
if ($cmd.ExecuteNonQuery() -ne -1)
{
    echo "Failed";
}
$cn2.Close();

Presumably you could substitute a different TSQL statement where it says dbcc freeproccache.

In my case I found duplicate paths in Servers/Tomcat5.5 at localhost-config/server.xml under tag. Removing the duplicates solved the problem.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

Get the day of the year from date, offset by 1 to start at 0, check if it is modulo three.

this may be a simpler approach:

(DesiredFigure).get_figure().savefig('figure_name.png')

i.e.

dfcorr.hist(bins=50).get_figure().savefig('correlation_histogram.png')

Click on settings in top tool bar;

Click on debugger;

In tree, highlight "gdb/cdb debugger" by clicking it

Click "create configuration"

Click default configuration, a dialogue will appear to the right for "executable path" with a button to the right.

Click on that button and it will bring up the file that codeblocks is installed in. Just keep clicking until you create the path to the gdb.exe (it sort of finds itself).

well, why don't you (get rid of sidebar and) squeeze the table so it is without show/hide effect? It looks odd to me now. The table is too robust.
Otherwise I think scunliffe's suggestion should do it. Or if you wish, you can just set the exact width of table and set either percentage or pixel width for table cells.

 public static String getcurrentDateAndTime(){

        Date c = Calendar.getInstance().getTime();
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
        String formattedDate = simpleDateFormat.format(c);
        return formattedDate;
    }

// String currentdate=  getcurrentDateAndTime();

Since people will be coming from Google, make sure you're in the right database.

Running SQL in the 'master' database will often return this error.

I'm not sure whether it is a new feature in later versions of matplotlib, but at least for 1.3.1, this is simply:

plt.title(figure_title, y=1.08)

This also works for plt.suptitle(), but not (yet) for plt.xlabel(), etc.

This post asked a similar question and used LINQ to solve it, maybe it will help you out too.

Use git archive branch-index | tar -x -C your-folder-on-PC to clone a branch to another folder. I think, then you can copy any file that you need

You need to use JavaScript in your HTML and make sure you are using forms so that. You may finally serialize the data using Ajax method to push the data from HTML into database

Try if this works:

You can use RoundingMode.#UNNECESSARY if you want/accept exception thrown otherwise

new BigDecimal(value).setScale(2, RoundingMode.UNNECESSARY);

If this rounding mode is specified on an operation that yields an inexact result, an ArithmeticException is thrown.

Exception if not integer value:

java.lang.ArithmeticException: Rounding necessary

I ran into this problem myself. The only solution I have is to record the macro in an excel workbook first. Then, drag and drop THE MODULE from the open workbook into the add-in modules. This will be a copy of the above module, but the keyboard shortcut you assigned to it will thankfully persist.

I just record a garbage macro and move it in there, then copy the code from my real module afterwords.

Felt so great to figure this out, I felt like I had to reply to the 5 year old posts I found on the subject!!!

Download the latest "sdk platform" and "sdk build tools" of same version like 23.* for 
both from "sdk Managar".

(for reference see above hosted image from back track). Then right click on your project -> properties -> Android -> in "project build properties" select "API level" 23 or the latest one which you updated. Then clean your project once.

Note: But all three should be in same version.

Here is another example, for compiling a java file in a nested directory.

I was trying to build this from the command line. This is an example from 'gradle', which has dependency 'commons-collection.jar'. For more info, please see 'gradle: java quickstart' example. -- of course, you would use the 'gradle' tools to build it. But i thought to extend this example, for a nested java project, with a dependent jar.

Note: You need the 'gradle binary or source' distribution for this, example code is in: 'samples/java/quickstart'

% mkdir -p temp/classes
% curl --get \
    http://central.maven.org/maven2/commons-collections/commons-collections/3.2.2/commons-collections-3.2.2.jar \
        --output commons-collections-3.2.2.jar

% javac -g -classpath commons-collections-3.2.2.jar \
     -sourcepath src/main/java -d temp/classes \
      src/main/java/org/gradle/Person.java 

% jar cf my_example.jar -C temp/classes org/gradle/Person.class
% jar tvf my_example.jar

Rather than WNetUseConnection, I would recommend NetUseAdd. WNetUseConnection is a legacy function that's been superceded by WNetUseConnection2 and WNetUseConnection3, but all of those functions create a network device that's visible in Windows Explorer. NetUseAdd is the equivalent of calling net use in a DOS prompt to authenticate on a remote computer.

If you call NetUseAdd then subsequent attempts to access the directory should succeed.

127.0.0.1 always points to localhost. On your home network you should have an IP address assigned by your internet router (dsl/cablemodem/whatever). You need to bind your website to this address. You should then be able to use the machine name to get to the website, but I would recommend actually editing the hosts file of the client computer in question to point a specific name at that computer. The hosts file can be found at c:\windows\system32\drivers\etc\hosts (use notepad) and the entry would look like:

192.168.1.1     mycomputername

In your compare method, o1 and o2 are already elements in the movieItems list. So, you should do something like this:

Collections.sort(movieItems, new Comparator<Movie>() {
    public int compare(Movie m1, Movie m2) {
        return m1.getDate().compareTo(m2.getDate());
    }
});

The compiler isn't smart enough to know that at least one of your if blocks will be executed. Therefore, it doesn't see that variables like annualRate will be assigned no matter what. Here's how you can make the compiler understand:

if (creditPlan == "0")
{
    // ...
}
else if (creditPlan == "1")
{
    // ...
}
else if (creditPlan == "2")
{
    // ...
}
else
{
    // ...
}

The compiler knows that with an if/else block, one of the blocks is guaranteed to be executed, and therefore if you're assigning the variable in all of the blocks, it won't give the compiler error.

By the way, you can also use a switch statement instead of ifs to maybe make your code cleaner.

If there is any single privilege that stands for ALL READ operations on database.

It depends on how you define "all read."

"Reading" from tables and views is the SELECT privilege. If that's what you mean by "all read" then yes:

GRANT SELECT ON *.* TO 'username'@'host_or_wildcard' IDENTIFIED BY 'password';

However, it sounds like you mean an ability to "see" everything, to "look but not touch." So, here are the other kinds of reading that come to mind:

"Reading" the definition of views is the SHOW VIEW privilege.

"Reading" the list of currently-executing queries by other users is the PROCESS privilege.

"Reading" the current replication state is the REPLICATION CLIENT privilege.

Note that any or all of these might expose more information than you intend to expose, depending on the nature of the user in question.

If that's the reading you want to do, you can combine any of those (or any other of the available privileges) in a single GRANT statement.

GRANT SELECT, SHOW VIEW, PROCESS, REPLICATION CLIENT ON *.* TO ...

However, there is no single privilege that grants some subset of other privileges, which is what it sounds like you are asking.

If you are doing things manually and looking for an easier way to go about this without needing to remember the exact grant you typically make for a certain class of user, you can look up the statement to regenerate a comparable user's grants, and change it around to create a new user with similar privileges:

mysql> SHOW GRANTS FOR 'not_leet'@'localhost';
+------------------------------------------------------------------------------------------------------------------------------------+
| Grants for not_leet@localhost                                                                                                      |
+------------------------------------------------------------------------------------------------------------------------------------+
| GRANT SELECT, REPLICATION CLIENT ON *.* TO 'not_leet'@'localhost' IDENTIFIED BY PASSWORD '*xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' |
+------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

Changing 'not_leet' and 'localhost' to match the new user you want to add, along with the password, will result in a reusable GRANT statement to create a new user.

Of, if you want a single operation to set up and grant the limited set of privileges to users, and perhaps remove any unmerited privileges, that can be done by creating a stored procedure that encapsulates everything that you want to do. Within the body of the procedure, you'd build the GRANT statement with dynamic SQL and/or directly manipulate the grant tables themselves.

In this recent question on Database Administrators, the poster wanted the ability for an unprivileged user to modify other users, which of course is not something that can normally be done -- a user that can modify other users is, pretty much by definition, not an unprivileged user -- however -- stored procedures provided a good solution in that case, because they run with the security context of their DEFINER user, allowing anybody with EXECUTE privilege on the procedure to temporarily assume escalated privileges to allow them to do the specific things the procedure accomplishes.

DISTINCT is not a function that applies only to some columns. It's a query modifier that applies to all columns in the select-list.

That is, DISTINCT reduces rows only if all columns are identical to the columns of another row.

DISTINCT must follow immediately after SELECT (along with other query modifiers, like SQL_CALC_FOUND_ROWS). Then following the query modifiers, you can list columns.

• RIGHT: SELECT DISTINCT foo, ticket_id FROM table...

  Output a row for each distinct pairing of values across ticket_id and foo.

• WRONG: SELECT foo, DISTINCT ticket_id FROM table...

  If there are three distinct values of ticket_id, would this return only three rows? What if there are six distinct values of foo? Which three values of the six possible values of foo should be output?
  It's ambiguous as written.

If we want to assign a scaler value eg: 10 to all rows of a new column in a df:

df = df.assign(new_col=lambda x:10)  # x is each row passed in to the lambda func

df will now have new column 'new_col' with value=10 in all rows.

To specify an application icon

1. In Solution Explorer, choose a project node (not the Solution node).
2. On the menu bar, choose Project, Properties.
3. When the Project Designer appears, choose the Application tab.
4. In the Icon list, choose an icon (.ico) file.

To specify an application icon and add it to your project

1. In Solution Explorer, choose a project node (not the Solution node).
2. On the menu bar, choose Project, Properties.
3. When the Project Designer appears, choose the Application tab.
4. Near the Icon list, choose the button, and then browse to the location of the icon file that you want.

The icon file is added to your project as a content file.

I made a POC for an Angular application using multiple modules and router-outlets to nest sub apps in a single page app. You can get the source code at: https://github.com/AhmedBahet/ng-sub-apps

Hope this will help

Simply use help(package="my_package") and look at the version shown.

This assumes there are no other package versions in the same .libPaths.

please go to .env file and change the value of AWS_DEFAULT_REGION to special area u want to...

AWS_DEFAULT_REGION = Asia/Dhaka

For my application i made a helper function:

function message( $message , $status = 'success', $redirectPath = null )
{
     $redirectPath = $redirectPath == null ? back() : redirect( $redirectPath );

     return $redirectPath->with([
         'message'   =>  $message,
         'status'    =>  $status,
    ]);
}

message layout, main.layouts.message:

@if($status)
   <div class="center-block affix alert alert-{{$status}}">
     <i class="fa fa-{{ $status == 'success' ? 'check' : $status}}"></i>
     <span>
        {{ $message }}
     </span>
   </div>
@endif

and import every where to show message:

@include('main.layouts.message', [
    'status'    =>  session('status'),
    'message'   =>  session('message'),
])

I known this is old, but I found a easier solution and it works on ie10, firefox and chrome:

<div id="wrapper">
  <div id="one">One</div>
  <div id="two">Two</div>
  <div id="three">Three</div>
</div> 

This is the css:

#wrapper {display:table;}
#one {display:table-footer-group;}
#three {display:table-header-group;}

And the result:

"Three"
"Two"
"One"

I found it here.

You can just use -i instead of -I {}

ls | xargs -i mv {} unix_{}

This also works perfectly.

• ls - lists all the files in the directory
• xargs - accepts all files line by line due to the -i option
• {} is the placeholder for all files, necessary if xargs gets more than two arguments as input

Using awk:

ls -lrt | grep '^-' | awk '{print "mv "$9" unix_"$9""}' | sh

What about this?

(function($) { 
   $(function() {
     // more code using $ as alias to jQuery
     // will be fired when document is ready
   });
})(jQuery);

I couldn't find a rationale by the original developers this quickly, but I can give you an educated guess based on a few years of Git experience.

No, not every branch is something you want to push to the outside world. It might represent a private experiment.

Moreover, where should git push send all the branches? Git can work with multiple remotes and you may want to have different sets of branches on each. E.g. a central project GitHub repo may have release branches; a GitHub fork may have topic branches for review; and a local Git server may have branches containing local configuration. If git push would push all branches to the remote that the current branch tracks, this kind of scheme would be easy to screw up.
