Solution:

That's it! Thanks Arjun Paudel for the link. Here's the solution as found on XNA Creator's Club Online. It's by Stephen Styrchak.

The following error suggests me to believe that you are compiling for 64bit:

The 'Microsoft .ACE.OELDB.12.0' provider is not registered on the local machine

I dont have express edition but are following steps valid in 2008 express?

In VC# Express, this property is missing, but you can still create an x86 configuration if you know where to look.

It looks like a long list of steps, but once you know where these things are it's a lot easier. Anyone who only has VC# Express will probably find this useful. Once you know about Configuration Manager, it'll be much more intuitive the next time.

1.In VC# Express 2005, go to Tools -> Options.
2.In the bottom-left corner of the Options dialog, check the box that says, "Show all settings".
3.In the tree-view on the left hand side, select "Projects and Solutions".
4.In the options on the right, check the box that says, "Show advanced build configuraions."
5.Click OK.
6.Go to Build -> Configuration Manager...
7.In the Platform column next to your project, click the combobox and select "<New...>".
8.In the "New platform" setting, choose "x86".
9.Click OK.
10.Click Close.
There, now you have an x86 configuration! Easy as pie! :-)

I also recommend using Configuration Manager to delete the Any CPU platform. You really don't want that if you ever have depedencies on 32-bit native DLLs (even indirect dependencies).

Call "setWarningMsg()" Method and pass the text that you want to show.

exm:- setWarningMsg("thank you for using java");


public static void setWarningMsg(String text){
    Toolkit.getDefaultToolkit().beep();
    JOptionPane optionPane = new JOptionPane(text,JOptionPane.WARNING_MESSAGE);
    JDialog dialog = optionPane.createDialog("Warning!");
    dialog.setAlwaysOnTop(true);
    dialog.setVisible(true);
}

Or Just use

JOptionPane optionPane = new JOptionPane("thank you for using java",JOptionPane.WARNING_MESSAGE);
JDialog dialog = optionPane.createDialog("Warning!");
dialog.setAlwaysOnTop(true); // to show top of all other application
dialog.setVisible(true); // to visible the dialog

You can use JOptionPane. (WARNING_MESSAGE or INFORMATION_MESSAGE or ERROR_MESSAGE)

I played a bit around and ended up with this crude solution:

function getElementsByAttribute(attribute, context) {
  var nodeList = (context || document).getElementsByTagName('*');
  var nodeArray = [];
  var iterator = 0;
  var node = null;

  while (node = nodeList[iterator++]) {
    if (node.hasAttribute(attribute)) nodeArray.push(node);
  }

  return nodeArray;
}

The usage is quite simple, and works even in IE8:

getElementsByAttribute('data-foo');
// or with parentNode
getElementsByAttribute('data-foo', document);

http://fiddle.jshell.net/9xaxf6jr/

But I recommend to use querySelector / All for this (and to support older browsers use a polyfill):

document.querySelectorAll('[data-foo]');

Assuming your Generic List is of type String:

TextWriter tw = new StreamWriter("SavedList.txt");

foreach (String s in Lists.verbList)
   tw.WriteLine(s);

tw.Close();

Alternatively, with the using keyword:

using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
   foreach (String s in Lists.verbList)
      tw.WriteLine(s);
}

Consider using the following which its far better than the accepted answer

DateTime UpdatedTime = _objHotelPackageOrder.UpdatedDate == null 
    ? DateTime.Now : (DateTime)_objHotelPackageOrder.UpdatedDate;

it went OK when i used Locale.US parametre in SimpleDateFormat

String dateString = "15 May 2013 17:38:34 +0300";
System.out.println(dateString);

SimpleDateFormat dateFormat = new SimpleDateFormat("dd MMM yyyy HH:mm:ss Z", Locale.US);
DateFormat targetFormat = new SimpleDateFormat("dd MMM yyyy HH:mm", Locale.getDefault());
String formattedDate = null;
Date convertedDate = new Date();
try {
     convertedDate = dateFormat.parse(dateString);
System.out.println(dateString);
formattedDate = targetFormat.format(convertedDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
 System.out.println(convertedDate);

For Swift 3 it's now: IndexPath(row: rowIndex, section: sectionIndex)

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

The argument associated with the %n will be treated as an int* and is filled with the number of total characters printed at that point in the printf.

function foo(value)
{
    var e = document.getElementById('leaveCode');
    if(e) e.value = value;
}

After trying most of the solutions here, the easiest thing I found was the obvious - using a temp file. I'm not sure what you want to do with your multiple line output, but you can then deal with it line by line using read. About the only thing you can't really do is easily stick it all in the same variable, but for most practical purposes this is way easier to deal with.

./myscript.sh > /tmp/foo
while read line ; do 
    echo 'whatever you want to do with $line'
done < /tmp/foo

Quick hack to make it do the requested action:

result=""
./myscript.sh > /tmp/foo
while read line ; do
  result="$result$line\n"
done < /tmp/foo
echo -e $result

Note this adds an extra line. If you work on it you can code around it, I'm just too lazy.

EDIT: While this case works perfectly well, people reading this should be aware that you can easily squash your stdin inside the while loop, thus giving you a script that will run one line, clear stdin, and exit. Like ssh will do that I think? I just saw it recently, other code examples here: https://unix.stackexchange.com/questions/24260/reading-lines-from-a-file-with-bash-for-vs-while

One more time! This time with a different filehandle (stdin, stdout, stderr are 0-2, so we can use &3 or higher in bash).

result=""
./test>/tmp/foo
while read line  <&3; do
    result="$result$line\n"
done 3</tmp/foo
echo -e $result

you can also use mktemp, but this is just a quick code example. Usage for mktemp looks like:

filenamevar=`mktemp /tmp/tempXXXXXX`
./test > $filenamevar

Then use $filenamevar like you would the actual name of a file. Probably doesn't need to be explained here but someone complained in the comments.

I had made a very stupid mistake when I had this same problem. I had added H2 DB for running unit test cases and hence I had set the scope to test in pom.xml. While running the application using mvn spring:run I removed the scope and it works fine now.

Strongly typed means that there are restrictions between conversions between types.

Statically typed means that the types are not dynamic - you can not change the type of a variable once it has been created.

In awk, FNR refers to the record number (typically the line number) in the current file and NR refers to the total record number. The operator == is a comparison operator, which returns true when the two surrounding operands are equal.

This means that the condition NR==FNR is only true for the first file, as FNR resets back to 1 for the first line of each file but NR keeps on increasing.

This pattern is typically used to perform actions on only the first file. The next inside the block means any further commands are skipped, so they are only run on files other than the first.

The condition FNR==NR compares the same two operands as NR==FNR, so it behaves in the same way.

you have a package.json file that shows the main configuration of your project, and a lockfile that contains the full details of your project configuration such as the urls that holds each of the package or libraries used in your project at the root folder of the project......

npm is the default package manager for Node.js.... All you need to do is call $ npm install from the terminal in the root directory where you have the package.json and lock file ...since you are not adding any particular package to be install ..... it will go through the lock file and download one after the other, the required packages from their urls written in the lock file if it isnt present in the project enviroment .....

you make sure you edit your package.json file .... to give an entry point to your app..... "name":"app.js" where app.js is the main script .. or index.js depending on the project naming convention...

then you can run..$ Node app.js or $ npm start if your package.json scripts has a start field config as such "scripts": { "start": "Node index.js", "test": "test" }..... which is indirectly still calling your $ Node app.js

string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_');

Alternatively, to change all characters except numbers and letters, try:

  true
elsif value.to_s == 'false'

From HandlerIntercepter's javadoc:

HandlerInterceptor is basically similar to a Servlet Filter, but in contrast to the latter it just allows custom pre-processing with the option of prohibiting the execution of the handler itself, and custom post-processing. Filters are more powerful, for example they allow for exchanging the request and response objects that are handed down the chain. Note that a filter gets configured in web.xml, a HandlerInterceptor in the application context.

As a basic guideline, fine-grained handler-related pre-processing tasks are candidates for HandlerInterceptor implementations, especially factored-out common handler code and authorization checks. On the other hand, a Filter is well-suited for request content and view content handling, like multipart forms and GZIP compression. This typically shows when one needs to map the filter to certain content types (e.g. images), or to all requests.

With that being said:

So where is the difference between Interceptor#postHandle() and Filter#doFilter()?

postHandle will be called after handler method invocation but before the view being rendered. So, you can add more model objects to the view but you can not change the HttpServletResponse since it's already committed.

doFilter is much more versatile than the postHandle. You can change the request or response and pass it to the chain or even block the request processing.

Also, in preHandle and postHandle methods, you have access to the HandlerMethod that processed the request. So, you can add pre/post-processing logic based on the handler itself. For example, you can add a logic for handler methods that have some annotations.

What is the best practise in which use cases it should be used?

As the doc said, fine-grained handler-related pre-processing tasks are candidates for HandlerInterceptor implementations, especially factored-out common handler code and authorization checks. On the other hand, a Filter is well-suited for request content and view content handling, like multipart forms and GZIP compression. This typically shows when one needs to map the filter to certain content types (e.g. images), or to all requests.

OS X is "LP64". This means that:

int is always 32-bits.

long long is always 64-bits.

NSInteger and long are always pointer-sized. That means they're 32-bits on 32-bit systems, and 64 bits on 64-bit systems.

The reason NSInteger exists is because many legacy APIs incorrectly used int instead of long to hold pointer-sized variables, which meant that the APIs had to change from int to long in their 64-bit versions. In other words, an API would have different function signatures depending on whether you're compiling for 32-bit or 64-bit architectures. NSInteger intends to mask this problem with these legacy APIs.

In your new code, use int if you need a 32-bit variable, long long if you need a 64-bit integer, and long or NSInteger if you need a pointer-sized variable.

You want has_key?:

if(params.has_key?(:one) && params.has_key?(:two))

Just checking if(params[:one]) will get fooled by a "there but nil" and "there but false" value and you're asking about existence. You might need to differentiate:

• Not there at all.
• There but nil.
• There but false.
• There but an empty string.

as well. Hard to say without more details of your precise situation.

The Javadocs from Sun for each collection class will generally tell you exactly what you want. HashMap, for example:

This implementation provides constant-time performance for the basic operations (get and put), assuming the hash function disperses the elements properly among the buckets. Iteration over collection views requires time proportional to the "capacity" of the HashMap instance (the number of buckets) plus its size (the number of key-value mappings).

TreeMap:

This implementation provides guaranteed log(n) time cost for the containsKey, get, put and remove operations.

TreeSet:

This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains).

(emphasis mine)

Simple and easy in javascipt

<script>

  document.getElementById("selectsearch").addEventListener("change", function(){

  var get_form =   document.getElementById("search-form") // get form 
  get_form.action =  '/search/' +  this.value; // assign value 

});

</script>

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

Reimport the project. If you install maven plugin you can use this.

Right click on the project -> Maven -> Reimport

Right click on the stored procedure and select Script Stored Procedure as | CREATE To | New Query Editor Window / Clipboard / File.

You can also do Modify when you right click on the stored procedure.

For multiple procedures at once, click on the Stored Procedures folder, hit F7 to open the Object Explorer Details pane, hold Ctrl and click to select all the ones that you want, and then right click and select Script Stored Procedure as | CREATE To.

If you want to specifically have your local ip address open when running ng serve you can do the following:

npm install internal-ip-cli --save
ng serve --open --host $(./node_modules/.bin/internal-ip --ipv4)

You can use something like this

if ($("#formID input:checkbox:checked").length > 0)
{
    // any one is checked
}
else
{
   // none is checked
}

I am also adding an answer that augments this a little bit because I came to this entry when searching for an answer, and this had almost what I needed, but I needed a bit more, which I got via @MrFlik 's answer and the R lazyeval vignettes.

I wanted to make a function that could take a dataframe and a vector of column names (as strings) that I want to be converted from a string to a Date object. I couldn't figure out how to make as.Date() take an argument that is a string and convert it to a column, so I did it as shown below.

Below is how I did this via SE mutate (mutate_()) and the .dots argument. Criticisms that make this better are welcome.

library(dplyr)

dat <- data.frame(a="leave alone",
                  dt="2015-08-03 00:00:00",
                  dt2="2015-01-20 00:00:00")

# This function takes a dataframe and list of column names
# that have strings that need to be
# converted to dates in the data frame
convertSelectDates <- function(df, dtnames=character(0)) {
    for (col in dtnames) {
        varval <- sprintf("as.Date(%s)", col)
        df <- df %>% mutate_(.dots= setNames(list(varval), col))
    }
    return(df)
}

dat <- convertSelectDates(dat, c("dt", "dt2"))
dat %>% str

        JSONObject jResult = new JSONObject();// main object
        JSONArray jArray = new JSONArray();// /ItemDetail jsonArray

        for (int i = 0; i < list.size(); i++) {
            JSONObject jGroup = new JSONObject();// /sub Object

            try {
                jGroup.put("ItemMasterID", list.get(i).get("ItemMasterID"));

You should use your custom input reader for faster results instead of extracting first character from reading String. Link for Custom ScanReader and explanation: https://gist.github.com/nik1010/5a90fa43399c539bb817069a14c3c5a8

Code for scanning Char :

BufferedInputStream br=new BufferedInputStream(System.in);
char a= (char)br.read();

What you describe is the correct way to handle this.

You said that you want to stay in the GUI. You can usually set the execute bit through the file properties menu. You could also learn how to create a custom action for the context menu to do this for you if you're so inclined. This depends on your desktop environment of course.

If you use a more advanced editor, you can script the action to happen when the file is saved. For example (I'm only really familiar with vim), you could add this to your .vimrc to make any new file that starts with "#!/*/bin/*" executable.

au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod +x <afile> | endif | endif

If you had use strict turned on, you would have found out that $++foo doesn't make any sense.

Here's how to do it:

use warnings;

my $file = 'SnPmaster.txt';
open my $info, $file or die "Could not open $file: $!";

while( my $line = <$info>)  {   
    print $line;    
    last if $. == 2;
}

close $info;

This takes advantage of the special variable $. which keeps track of the line number in the current file. (See perlvar)

If you want to use a counter instead, use

my $count = 0;
while( my $line = <$info>)  {   
    print $line;    
    last if ++$count == 2;
}

To quickly find a meaningful error message by inspecting the error during debugging:

• Add a quick watch for:

  ((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors
  

• Drill down into EntityValidationErrors like this:

  (collection item e.g. [0]) > ValidationErrors > (collection item e.g. [0]) > ErrorMessage

Here is a method using a lookup table of thresholds and associated colours to map the colours to the variable of interest.

 # make a grid 'Grd' of points and number points for side of square 'GrdD'
Grd <- expand.grid(seq(0.5,400.5,10),seq(0.5,400.5,10))
GrdD <- length(unique(Grd$Var1))

# Add z-values to the grid points
Grd$z <- rnorm(length(Grd$Var1), mean = 10, sd =2)

# Make a vector of thresholds 'Brks' to colour code z 
Brks <- c(seq(0,18,3),Inf)

# Make a vector of labels 'Lbls' for the colour threhsolds
Lbls <- Lbls <- c('0-3','3-6','6-9','9-12','12-15','15-18','>18')

# Make a vector of colours 'Clrs' for to match each range
Clrs <- c("grey50","dodgerblue","forestgreen","orange","red","purple","magenta")

# Make up lookup dataframe 'LkUp' of the lables and colours 
LkUp <- data.frame(cbind(Lbls,Clrs),stringsAsFactors = FALSE)

# Add a new variable 'Lbls' the grid dataframe mapping the labels based on z-value
Grd$Lbls <- as.character(cut(Grd$z, breaks = Brks, labels = Lbls))

# Add a new variable 'Clrs' to the grid dataframe based on the Lbls field in the grid and lookup table
Grd <- merge(Grd,LkUp, by.x = 'Lbls')

# Plot the grid using the 'Clrs' field for the colour of each point
plot(Grd$Var1,
     Grd$Var2,
     xlim = c(0,400),
     ylim = c(0,400),
     cex = 1.0,
     col = Grd$Clrs,
     pch = 20,
     xlab = 'mX',
     ylab = 'mY',
     main = 'My Grid',
     axes = FALSE,
     labels = FALSE,
     las = 1
)

axis(1,seq(0,400,100))
axis(2,seq(0,400,100),las = 1)
box(col = 'black')

legend("topleft", legend = Lbls, fill = Clrs, title = 'Z')

Have your tried using the 'return' keyword?

def rps():
    return True

If you want a ksh only method that is as fast as "test", you can do something like:

contains() # haystack needle
{
    haystack=${1/$2/}
    if [ ${#haystack} -ne ${#1} ] ; then
        return 1
    fi
    return 0
}

It works by deleting the needle in the haystack and then comparing the string length of old and new haystacks.

Whilst using Symbol as the enum value works fine for simple use cases, it can be handy to give properties to enums. This can be done by using an Object as the enum value containing the properties.

For example we can give each of the Colors a name and hex value:

/**
 * Enum for common colors.
 * @readonly
 * @enum {{name: string, hex: string}}
 */
const Colors = Object.freeze({
  RED:   { name: "red", hex: "#f00" },
  BLUE:  { name: "blue", hex: "#00f" },
  GREEN: { name: "green", hex: "#0f0" }
});

Including properties in the enum avoids having to write switch statements (and possibly forgetting new cases to the switch statements when an enum is extended). The example also shows the enum properties and types documented with the JSDoc enum annotation.

Equality works as expected with Colors.RED === Colors.RED being true, and Colors.RED === Colors.BLUE being false.

You can easily do this using Bootstrap UI directive.

This answer is a modification of the answer given by @Scotty.NET, I have changed the code because <pagination> directive is deprecated now.

Following code generates the pagination:

<ul uib-pagination 
    boundary-links="true"  
    total-items="totalItems"  
    items-per-page="itemsPerPage"  
    ng-model="currentPage"  
    ng-change="pageChanged()"  
    class="pagination"  
    previous-text="&lsaquo;"  
    next-text="&rsaquo;"  
    first-text="&laquo;"  
    last-text="&raquo;">
</ul>

To make it functional, use this in your controller:

$scope.filteredData = []
$scope.totalItems = $scope.data.length;
$scope.currentPage = 1;
$scope.itemsPerPage = 5;

$scope.setPage = function (pageNo) {
    $scope.currentPage = pageNo;
};

$scope.pageChanged = function() {
    var begin = (($scope.currentPage - 1) * $scope.itemsPerPage)
    , end = begin + $scope.itemsPerPage;

    $scope.filteredData = $scope.data.slice(begin, end);
};

$scope.pageChanged();

Refer to this for more options of pagination: Bootstrap UI Pagination Directive

Confirming I was able to use the answer posted by MadBoy and edited by Otiel on both MS SQL Server 2012 and 2014 in addition to the versions previously listed using varbinary(MAX) columns.

If you are wondering why you cannot "Filestream" (noted in a separate answer) as a datatype in the SQL Server table designer or why you cannot set a column's datatype to "Filestream" using T-SQL, it is because FILESTREAM is a storage attribute of the varbinary(MAX) datatype. It is not a datatype on its own.

See these articles on setting up and enabling FILESTREAM on a database: https://msdn.microsoft.com/en-us/library/cc645923(v=sql.120).aspx

http://www.kodyaz.com/t-sql/default-filestream-filegroup-is-not-available-in-database.aspx

Once configured, a filestream enabled varbinary(max) column can be added as so:

ALTER TABLE TableName

ADD ColumnName varbinary(max) FILESTREAM NULL

GO

We finally found an answer of sorts. First, the problem: the table always sizes itself around the content, rather than forcing the content to fit in the table. That limits your options.

We did it by setting the content div to display:none, letting the table size itself, and then in javascript setting the height and width of the content div to the inner height and width of the enclosing td tag. Show the content div. Repeat the process when the window is resized.

It depends on how you set the defaults for the dropdown. Use selected value, but you have to set the selected value. For instance, I populate the datasource with the name and id field for the table/list. I set the selected value to the id field and the display to the name. When I select, I get the id field. I use this to search a relational table and find an entity/record.

import java.util.*;
public class lcm {
    public static void main(String args[])
    {
        int lcmresult=1;
        System.out.println("Enter the number1: ");
        Scanner s=new Scanner(System.in);
        int a=s.nextInt();
        System.out.println("Enter the number2: ");
        int b=s.nextInt();
        int max=a>b?a:b;
        for(int i=2;i<=max;i++)
        {
            while(a%i==0||b%i==0)
            {
                lcmresult=lcmresult*i;
                if(a%i==0)
                    a=a/i;
                if(b%i==0)
                    b=b/i;
                if(a==1&&b==1)
                    break;
            }
        }
    System.out.println("lcm: "+lcmresult);
}
}

It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

You are most likely seeing the unexpected behavior because your text file was created on Windows, so the end of line sequence is \r\n. You can use dos2unix to convert it to a UNIX style text file before running sed or use

sed -r "/^\r?$/d"

to remove blank lines whether or not the carriage return is there.

Add this code below. Once turns it off, releases the filter. Second time turns it back on without filters.

Not very elegant, but served my purpose.

ActiveSheet.ListObjects("MyTable").Range.AutoFilter

'then call it again?
ActiveSheet.ListObjects("MyTable").Range.AutoFilter

Personally, I'd return the full, native datetime value and format this in the client code.

That way, you can use the user's locale setting to give the correct meaning to that user.

"11/12" is ambiguous. Is it:

• 12th November
• 11th December

I'm not addressing the question directly, but providing an alternative that might also meet your requirement in a more node.js fashion way.

Functionally the requirements are:

1. Have the logic (app) running in the background
2. Be able to start/stop the logic
3. Automatically start the logic when system boots up

These requirements can be satisfied by using a process manager (PM) and making the process manager start on system startup. Two good PMs that are Windows-friendly are:

• PM2
• forever

To make the PM start automatically, the most simple way is to create a scheduled task with a "At Startup" trigger:

There are several "compilers" of PHP code. Most of them do not support all of PHP features, since these simply must be interpreted during run time.

We are using Phalanger - http://www.php-compiler.net/ - that is supporting even those dirty PHP dynamic features, and still is able to compile them as .NET assembly, that can be distributed as a standalone DLL.

firstly use

show create table table_name;

to see the descriptive structure of your table.

There you may see constraints respective to foreign keys you used in that table. First delete the respective constraint with

alter table table_name drop constraint constraint_name;

and then delete the respective foreign keys or column you wanted...GoodLuck!!

Check if your class has right Target Membership.

You need to add a reference to System.Windows.Forms.dll, then use the System.Windows.Forms.FolderBrowserDialog class.

Adding using WinForms = System.Windows.Forms; will be helpful.

SELECT table1.col_a, table1.col_b, table2.col_c 
  FROM table1

Try running fuser command

[root@guest2 ~]# fuser -mv /home

USER PID ACCESS COMMAND

/home: root 2919 f.... automount

[root@guest2 ~]# kill -9 2919

autofs service is known to cause this issue.

You can use command

#service autofs stop

And try again.

You should read Supporting multiple screens. You must define dpi on your emulator. 240 is hdpi, 160 is mdpi and below that are usually ldpi.

Extract from Android Developer Guide link above:

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).  
480dp: a tweener tablet like the Streak (480x800 mdpi).  
600dp: a 7” tablet (600x1024 mdpi).  
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

This can also arise in connection with a bug in certain versions of Percona Toolkit's online-schema-change tool. To mutate a large table, pt-osc first creates a duplicate table and copies all the records into it. Under some circumstances, some versions of pt-osc 2.2.x will try to give the constraints on the new table the same names as the constraints on the old table.

A fix was released in 2.3.0.

See https://bugs.launchpad.net/percona-toolkit/+bug/1498128 for more details.

Note that you have to be careful if your row contains a factor. Here is an example:

df_1 = data.frame(V1 = factor(11:15),
                  V2 = 21:25)
df_1[1,] %>% as.numeric() # you expect 11 21 but it returns 
[1] 1 21

Here is another example (by default data.frame() converts characters to factors)

df_2 = data.frame(V1 = letters[1:5],
                  V2 = 1:5)
df_2[3,] %>% as.numeric() # you expect to obtain c 3 but it returns
[1] 3 3
df_2[3,] %>% as.character() # this won't work neither
[1] "3" "3"

To prevent this behavior, you need to take care of the factor, before extracting it:

df_1$V1 = df_1$V1 %>% as.character() %>% as.numeric()
df_2$V1 = df_2$V1 %>% as.character()
df_1[1,] %>% as.numeric()
[1] 11  21
df_2[3,] %>% as.character()
[1] "c" "3"

The accepted answer kinda has a bug

var from = $("#datepicker").val().split("-")
var f = new Date(from[2], from[1] - 1, from[0])

Consider if the datepicker contains "77-78-7980" which is obviously not a valid date. This would result in:

var f = new Date(7980, 77, 77);
=> Date 7986-08-15T22:00:00.000Z

Which is probably not the desired result.

The reason for this is explained on the MDN site:

Where Date is called as a constructor with more than one argument, if values are greater than their logical range (e.g. 13 is provided as the month value or 70 for the minute value), the adjacent value will be adjusted. E.g. new Date(2013, 13, 1) is equivalent to new Date(2014, 1, 1).

A better way to solve the problem is:

const stringToDate = function(dateString) {
  const [dd, mm, yyyy] = dateString.split("-");
  return new Date(`${yyyy}-${mm}-${dd}`);
};

console.log(stringToDate('04-04-2019'));
// Date 2019-04-04T00:00:00.000Z

console.log(stringToDate('77-78-7980'));
// Invalid Date

This gives you the possibility to handle invalid input.

For example:

const date = stringToDate("77-78-7980");

if (date === "Invalid Date" || isNaN(date)) {
  console.log("It's all gone bad");
} else {
  // Do something with your valid date here
}

One option that I haven't see mentioned so far is that (for my setup) the Developer Option 'Select USB Configuration' must be set to MTP (Media Transfer Protocol).

Can you try this,

echo date("Y-m-d H:i:s", 1388516401);

As noted by theGame,

This means that you pass in a string value for the time, and optionally a value for the current time, which is a UNIX timestamp. The value that is returned is an integer which is a UNIX timestamp.

echo strtotime("2014-01-01 00:00:01");

This will return into the value 1388516401, which is the UNIX timestamp for the date 2014-01-01. This can be confirmed using the date() function as like below:

echo date('Y-m-d', 1198148400); // echos 2014-01-01

If you wish to support different orientations in debug and release builds, write so (see https://developer.android.com/studio/build/gradle-tips#share-properties-with-the-manifest).

In build.gradle of your app folder write:

android {
    ...
    buildTypes {
        debug {
            applicationIdSuffix '.debug'
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            // Creates a placeholder property to use in the manifest.
            manifestPlaceholders = [orientation: "fullSensor"]
        }
        release {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            // Creates a placeholder property to use in the manifest.
            manifestPlaceholders = [orientation: "portrait"]
        }
    }
}

Then in AndroidManifest you can use this variable "orientation" in any Activity:

<activity
    android:name=".LoginActivity"
    android:screenOrientation="${orientation}" />

You can add android:configChanges:

manifestPlaceholders = [configChanges: "", orientation: "fullSensor"] in debug and manifestPlaceholders = [configChanges: "keyboardHidden|orientation|screenSize", orientation: "portrait"] in release,

<activity
    android:name=".LoginActivity"
    android:configChanges="${configChanges}"
    android:screenOrientation="${orientation}" />

Here is my snippet for such thing. You basically import or copy the function to your code. getCredentials will create the encrypted file if it does not exist and return a dictionaty, and updateCredential will update.

import os

def getCredentials():
    import base64

    splitter='<PC+,DFS/-SHQ.R'
    directory='C:\\PCT'

    if not os.path.exists(directory):
        os.makedirs(directory)

    try:
        with open(directory+'\\Credentials.txt', 'r') as file:
            cred = file.read()
            file.close()
    except:
        print('I could not file the credentials file. \nSo I dont keep asking you for your email and password everytime you run me, I will be saving an encrypted file at {}.\n'.format(directory))

        lanid = base64.b64encode(bytes(input('   LanID: '), encoding='utf-8')).decode('utf-8')  
        email = base64.b64encode(bytes(input('   eMail: '), encoding='utf-8')).decode('utf-8')
        password = base64.b64encode(bytes(input('   PassW: '), encoding='utf-8')).decode('utf-8')
        cred = lanid+splitter+email+splitter+password
        with open(directory+'\\Credentials.txt','w+') as file:
            file.write(cred)
            file.close()

    return {'lanid':base64.b64decode(bytes(cred.split(splitter)[0], encoding='utf-8')).decode('utf-8'),
            'email':base64.b64decode(bytes(cred.split(splitter)[1], encoding='utf-8')).decode('utf-8'),
            'password':base64.b64decode(bytes(cred.split(splitter)[2], encoding='utf-8')).decode('utf-8')}

def updateCredentials():
    import base64

    splitter='<PC+,DFS/-SHQ.R'
    directory='C:\\PCT'

    if not os.path.exists(directory):
        os.makedirs(directory)

    print('I will be saving an encrypted file at {}.\n'.format(directory))

    lanid = base64.b64encode(bytes(input('   LanID: '), encoding='utf-8')).decode('utf-8')  
    email = base64.b64encode(bytes(input('   eMail: '), encoding='utf-8')).decode('utf-8')
    password = base64.b64encode(bytes(input('   PassW: '), encoding='utf-8')).decode('utf-8')
    cred = lanid+splitter+email+splitter+password
    with open(directory+'\\Credentials.txt','w+') as file:
        file.write(cred)
        file.close()

cred = getCredentials()

updateCredentials()

First, use the bounding boxes as described by Jonathan Holland to find if you may have a collision.

From the (multi-color) sprites, create black and white versions. You probably already have these if your sprites are transparent (i.e. there are places which are inside the bounding box but you can still see the background). These are "masks".

Use Image.getRGB() on the mask to get at the pixels. For each pixel which isn't transparent, set a bit in an integer array (playerArray and enemyArray below). The size of the array is height if width <= 32 pixels, (width+31)/32*height otherwise. The code below is for width <= 32.

If you have a collision of the bounding boxes, do this:

// Find the first line where the two sprites might overlap
int linePlayer, lineEnemy;
if (player.y <= enemy.y) {
    linePlayer = enemy.y - player.y;
    lineEnemy = 0;
} else {
    linePlayer = 0;
    lineEnemy = player.y - enemy.y;
}
int line = Math.max(linePlayer, lineEnemy);

// Get the shift between the two
x = player.x - enemy.x;
int maxLines = Math.max(player.height, enemy.height);
for ( line < maxLines; line ++) {
    // if width > 32, then you need a second loop here
    long playerMask = playerArray[linePlayer];
    long enemyMask = enemyArray[lineEnemy];
    // Reproduce the shift between the two sprites
    if (x < 0) playerMask << (-x);
    else enemyMask << x;
    // If the two masks have common bits, binary AND will return != 0
    if ((playerMask & enemyMask) != 0) {
        // Contact!
    }

}

You can try this:

: ${depth?"Error Message"} ## when your depth variable is not even declared or is unset.

NOTE: Here it's just ? after depth.

or

: ${depth:?"Error Message"} ## when your depth variable is declared but is null like: "depth=". 

NOTE: Here it's :? after depth.

Here if the variable depth is found null it will print the error message and then exit.

A segementation fault is an internal error in php (or, less likely, apache). Oftentimes, the segmentation fault is caused by one of the newer and lesser-tested php modules such as imagemagick or subversion.

Try disabling all non-essential modules (in php.ini), and then re-enabling them one-by-one until the error occurs. You may also want to update php and apache.

If that doesn't help, you should report a php bug.

I would suggest looking at lodash and how they implemented the trim function.

See Lodash Trim for the documentation and the source to see the exact code that does the trimming.

I know this does not provide an exact answer your question, but I think it's good to set a reference to a library on such a question since others might find it useful.

UPDATE:
I added two new methods that instead of utilizing cls to hide the input they create a new pop-up with one line only.

The drawbacks are that one method (method 2) leaves junk in the registry - "If run without proper rights", and the other one (method three) appends some junk to the script. Needless to say that it can easily be written to any tmp file and deleted I just tried to come up with an alternative.

int is inherently finite; there's no value that satisfies your requirements.

If you're willing to change the type of b, though, you can do this with operator overrides:

class infinitytype {};

template<typename T>
bool operator>(const T &, const infinitytype &) {
  return false;
}

template<typename T>
bool operator<(const T &, const infinitytype &) {
  return true;
}

bool operator<(const infinitytype &, const infinitytype &) {
  return false;
}


bool operator>(const infinitytype &, const infinitytype &) {
  return false;
}

// add operator==, operator!=, operator>=, operator<=...

int main() {
  std::cout << ( INT_MAX < infinitytype() ); // true
}

Margin: 0 auto; is the correct answer for horizontal centering only. For centering both ways something like this will work, using jquery:

var cenBtn = function() {
   var W = $(window).width();
   var H = $(window).height();
   var BtnW = insert button width;
   var BtnH = insert button height;
   var LeftOff = (W / 2) - (BtnW / 2);
   var TopOff = (H / 2) - (BtnH /2);
       $("#buttonID").css({left: LeftOff, top: TopOff});
};

$(window).bind("load, resize", cenBtn);

Update ... five years later, one could use flexbox on the parent DIV element to easily center the button both horizontally and vertically.

Problem may not be associated with Seaborn but Utils package which may not be installed

sudo pip uninstall requests

and reinstalling, it no longer would work at all. Luckily, dnf install python-requests fixed the whole thing...

Also check for utils package is installed or not

You can install package using

sudo pip install utils

Check this link Python ImportError: cannot import name utils

I had to restart the rails application on the production so I looked for an another answer. I have found it below:

http://wiki.ocssolutions.com/Restarting_a_Rails_Application_Using_Passenger

You can use the Search & Replace feature with this regex ^([\w\d\_\.\s\-]*)$ to find text and the replaced text is "$1".

Grab it from here

Just choose required version and click 'Binary'. e.g direct link to version 2.5

In this specific case it is Smarty, but it could also be Jinja2 templates. They usually also have a .tpl extension.

You should also look into commands.getstatusoutput

This returns a tuple of length 2.. The first is the return integer ( 0 - when the commands is successful ) second is the whole output as will be shown in the terminal.

For ls

    import commands
    s=commands.getstatusoutput('ls')
    print s
    >> (0, 'file_1\nfile_2\nfile_3')
    s[1].split("\n")
    >> ['file_1', 'file_2', 'file_3']

How about this:

   ISNULL(SUBSTRING(REPLACE((select ',' FName as 'data()' from NameList for xml path('')), ' ,',', '), 2, 300), '') 'MyList'

Where the "300" could be any width taking into account the max number of items you think will show up.

First, &:name is a shortcut for &:name.to_proc, where :name.to_proc returns a Proc (something that is similar, but not identical to a lambda) that when called with an object as (first) argument, calls the name method on that object.

Second, while & in def foo(&block) ... end converts a block passed to foo to a Proc, it does the opposite when applied to a Proc.

Thus, &:name.to_proc is a block that takes an object as argument and calls the name method on it, i. e. { |o| o.name }.

Well in SQL Server, generally, primary key is automatically indexed. This is true, but it not guaranteed of faster query. The primary key will give you excellent performance when there is only 1 field as primary key. But, when there are multiple field as primary key, then the index is based on those fields.

For example: Field A, B, C are the primary key, thus when you do query based on those 3 fields in your WHERE CLAUSE, the performance is good, BUT when you want to query with Only C field in the WHERE CLAUSE, you wont get good performance. Thus, to get your performance up and running, you will need to index C field manually.

Most of the time, you wont see the issue till you hits more than 1 million records.

You may use jQuery.grep():

var found_names = $.grep(names, function(v) {
    return v.name === "Joe" && v.age < 30;
});

--reverse is also helpful since you want the first commit that made the change:

git log --all -p --reverse --source -S 'needle'

This way older commits will appear first.

Set them so that their flex-basis is 0 (so all elements have the same starting point), and allow them to grow:

flex: 1 1 0px

Your IDE or linter might mention that the unit of measure 'px' is redundant. If you leave it out (like: flex: 1 1 0), IE will not render this correctly. So the px is required to support Internet Explorer, as mentioned in the comments by @fabb;

The Post-Build Event (under Build Events, in the properties dialog) of an imported project, had an environment variable which was not defined.
Navigated to Control Panel\All Control Panel Items\System\Advanced system settings to add the appropriate environment variable, and doing no more than restarting VS2017 resolved the error.
Also, following on from @Seans and other answers regarding multiple project races/contentions, create a temp folder in the output folder like so,

and select the project producing the preferred output:

and build (no rebuild/clean) is a speedy solution.

This is quite a misleading status. It should be called "reading and filtering data".

This means that MySQL has some data stored on the disk (or in memory) which is yet to be read and sent over. It may be the table itself, an index, a temporary table, a sorted output etc.

If you have a 1M records table (without an index) of which you need only one record, MySQL will still output the status as "sending data" while scanning the table, despite the fact it has not sent anything yet.

$('input:checked').map(function(i, e) {return e.value}).toArray();

For mixed position and index, use .ix. BUT you need to make sure that your index is not of integer, otherwise it will cause confusions.

df.ix[0, 'COL_NAME'] = x

Update:

Alternatively, try

df.iloc[0, df.columns.get_loc('COL_NAME')] = x

Example:

import pandas as pd
import numpy as np

# your data
# ========================
np.random.seed(0)
df = pd.DataFrame(np.random.randn(10, 2), columns=['col1', 'col2'], index=np.random.randint(1,100,10)).sort_index()

print(df)

Under Linux, to find the location of $JAVA_HOME:

readlink -f /usr/bin/java | sed "s:bin/java::"

the cacerts are under lib/security/cacerts:

$(readlink -f /usr/bin/java | sed "s:bin/java::")lib/security/cacerts

Under mac OS X , to find $JAVA_HOME run:

/usr/libexec/java_home

the cacerts are under Home/lib/security/cacerts:

$(/usr/libexec/java_home)/lib/security/cacerts

UPDATE (OS X with JDK)

above code was tested on computer without JDK installed. With JDK installed, as pR0Ps said, it's at

$(/usr/libexec/java_home)/jre/lib/security/cacerts

you can try this function for multi-purpose

function ManageData($table_name='',$condition=array(),$udata=array(),$is_insert=false){
$resultArr = array();
$ci = & get_instance();
if($condition && count($condition))
    $ci->db->where($condition);
if($is_insert)
{
    $ci->db->insert($table_name,$udata);
    return 0;
}
else
{
    $ci->db->update($table_name,$udata);
    return 1;
}

}

You just need to do it in correct syntax. Let me give you a minimal example I just did with Python interactive shell:

>>> class MyNameClass():
...   def __init__(self, myname):
...       print myname
... 
>>> p1 = MyNameClass('John')
John

bool exists = arr.Contains("One");

Delete the "target" folder under the offending module. Then Build | Rebuild Project. Also make sure your clear the web browsers cache.

From python3 onwards you can use

a == []

to check if the list is empty

EDIT : This works with python2.7 too..

I am not sure why there are so many complicated answers. It's pretty clear and straightforward

ThiefMaster's answer is 100% correct, although I came across a similar problem where I needed to fetch a property from a nested object (object within an object), so as an alternative to his answer, you can create a recursive solution that will allow you to define a nomenclature to grab any property, regardless of depth:

function fetchFromObject(obj, prop) {

    if(typeof obj === 'undefined') {
        return false;
    }

    var _index = prop.indexOf('.')
    if(_index > -1) {
        return fetchFromObject(obj[prop.substring(0, _index)], prop.substr(_index + 1));
    }

    return obj[prop];
}

Where your string reference to a given property ressembles property1.property2

I don't understand why the files were relocated to /platform-tools from /tools. It seems ALL development tools I have tried, appcelerator for one, have their setup software look for these files in /tools and fail setup. The "work around" involves a few different bits of trickery wherein you either...1) set up a soft link to tell the operating system "if you look for file "x" here it is really over here. or 2) simpler method ... make a copy of all the /platform-tools default (pre-additional android sdk installations) files and place them into the /tools folder. this circumvents the relocation that the newer sdk have done. Then of course YOU MUST SET PATH ENVIRONMENT VARIABLES TO POINT TO THE SDK LOCATION (sometimes to the Android-sdk-[operating system name:Android-sdk-windows or Android-sdk-mac_x86 ect. ] and to the /platform-tools and sometimes to /tools. it is a trial and error pain. But when it finally is working ...it works.

<select name="country" formControlName="country" id="country" 
       class="formcontrol form-control-element" [(ngModel)]="country">
   <option value="90">Turkey</option>
   <option value="1">USA</option>
   <option value="30">Greece</option>
</select>

name="country"
formControlName="country" 
[(ngModel)]="country" 

Those are the three things need to use ngModel inside a formGroup directive.

Note that same name should be used.

This should work:

DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table; 
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0  
BEGIN  

       --Do stuff with scalar values

       FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;

Use the push() function to append to an array:

// initialize array
var arr = [
    "Hi",
    "Hello",
    "Bonjour"
];

// append new value to the array
arr.push("Hola");

Now array is

var arr = [
    "Hi",
    "Hello",
    "Bonjour"
    "Hola"
];

// append multiple values to the array
arr.push("Salut", "Hey");

Now array is

var arr = [
    "Hi",
    "Hello",
    "Bonjour"
    "Hola"
    "Salut"
    "Hey"
];

// display all values
for (var i = 0; i < arr.length; i++) {
    console.log(arr[i]);
}

Will print:

Hi
Hello
Bonjour
Hola 
Salut
Hey

Update

If you want to add the items of one array to another array, you can use Array.concat:

var arr = [
    "apple",
    "banana",
    "cherry"
];

arr = arr.concat([
    "dragonfruit",
    "elderberry",
    "fig"
]);

console.log(arr);

Will print

["apple", "banana", "cherry", "dragonfruit", "elderberry", "fig"]

C didn't use to have consts, so #defines were the only way of providing constant values. Both C and C++ do have them now, so there is no point in using them, except when they are going to be tested with #ifdef/ifndef.

org.apache.commons.lang3.StringEscapeUtils from commons-lang3 is marked deprecated now. You can use org.apache.commons.text.StringEscapeUtils#unescapeJava(String) instead. It requires an additional Maven dependency:

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-text</artifactId>
            <version>1.4</version>
        </dependency>

and seems to handle some more special cases, it e.g. unescapes:

• escaped backslashes, single and double quotes
• escaped octal and unicode values
• \\b, \\n, \\t, \\f, \\r

It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:

http://www.django-rest-framework.org/api-guide/renderers/

Using the HTTP accept header may provide an alternative source for your "if something".

in my case I show that the error log was going to /var/log/php-fpm/www-error.log . so I commented this line in /etc/php-fpm.d/www.conf

php_flag[display_errors]   is commented
php_flag[display_errors] = on  log will be at /var/log/php-fpm/www-error.log

and as said above I also uncommented this line

catch_workers_output = yes

Now I can see logs in the file specified by nginx.

I have build a small demo project on this you could have a look to it Link to project

You can look at the Columns property of a given DataTable, it is a list of all columns in the table.

private void PrintValues(DataTable table)
{
    foreach(DataRow row in table.Rows)
    {
        foreach(DataColumn column in table.Columns)
        {
            Console.WriteLine(row[column]);
        }
    }
}

It's better to avoid unnecessary autoboxing for 2 reasons.

For one thing, it's a bit slower than int < int, as you're (sometimes) creating an extra object;

void doSomethingWith(Integer integerObject){ ...
  int i = 1000;
  doSomethingWith(i);//gets compiled into doSomethingWith(Integer.valueOf(i));

The bigger issue is that hidden autoboxing can hide exceptions:

void doSomethingWith (Integer count){
  if (count>0)  // gets compiled into count.intValue()>0

Calling this method with null will throw a NullPointerException.

The split between primitives and wrapper objects in java was always described as a kludge for speed. Autoboxing almost hides this, but not quite - it's cleaner just to keep track of the type. So if you've got an Integer object, you can just call compare() or intValue(), and if you've got the primitive just check the value directly.

Another way to build fluid full screen iframe:

Embedded video fills entire viewport area when page loads

Nice approach for landing pages with video or any embedded content. You can have any additional content below of embedded video, which is revealed when scrolling page down.

Ask about "this". This is one good question which can be true test of JavaScript developer.

using the link method, the stylesheets are loaded parallel (faster and better), and nearly all browsers support link

import loads any extra css files one-by-one (slower), and could give you Flash Of Unstyled Content

You could also do something like df = df[['x', 'y', 'a', 'b']]

import pandas as pd
frame = pd.DataFrame({'one thing':[1,2,3,4],'second thing':[0.1,0.2,1,2],'other thing':['a','e','i','o']})
frame = frame[['second thing', 'other thing', 'one thing']]
print frame
   second thing other thing  one thing
0           0.1           a          1
1           0.2           e          2
2           1.0           i          3
3           2.0           o          4

Also, you can get the list of columns with:

cols = list(df.columns.values)

The output will produce something like this:

['x', 'y', 'a', 'b']

Which is then easy to rearrange manually.

This is different for each browser, in IE and windows you need to create what they call a pluggable protocol handler.

The basic steps are as follows:

1. Implement the IInternetProtocol interface.
2. Implement the IInternetProtocolRoot interface.
3. Implement the IClassFactory interface.
4. Optional. Implement the IInternetProtocolInfo interface. Support for the HTTP protocol is provided by the transaction handler.
5. If IInternetProtocolInfo is implemented, provide support for PARSE_SECURITY_URL and PARSE_SECURITY_DOMAIN so the URL security zone manager can handle the security properly. Write the code for your protocol handler.
6. Provide support for BINDF_NO_UI and BINDF_SILENTOPERATION.
7. Add a subkey for your protocol handler in the registry under HKEY_CLASSES_ROOT\PROTOCOLS\Handler.
8. Create a string value, CLSID, under the subkey and set the string to the CLSID of your protocol handler.

See About Asynchronous Pluggable Protocols on MSDN for more details on the windows side. There is also a sample in the windows SDK.

A quick google also showed this article on codeproject: http://www.codeproject.com/KB/IP/DataProtocol.aspx.

Finally, as a security guy I have to point out that this code needs to be battle hardened. It's at a high risk because to do it reliably you can't do it in managed code and have to do it in C++ (I suppose you could use VB6). You should consider whether you really need to do this and if you do, design it carefully and code it securely. An attacker can easily control the content that gets passed to you by simply including a link on a page. For example if you have a simple buffer overflow then nobody better do this: <a href="custom:foooo{insert long string for buffer overflow here}"> Click me for free porn</a>

Strongly consider using strsafe and the new secure CRT methods included in the VC8 and above compilers. See http://blogs.msdn.com/michael_howard/archive/2006/02/27/540123.aspx if you have no idea what I'm talking about.

Edit, since i misunderstood the question:

Just put the Helper class in __init__.py. Thats perfectly pythonic. It just feels strange coming from languages like Java.

Azure Data Studio with Postgres addin is the tool of choice to manage postgres databases for me. Check it out. https://docs.microsoft.com/en-us/sql/azure-data-studio/quickstart-postgres?view=sql-server-ver15

Here is a good choice for gradients for both platforms iOS and Android:

https://github.com/react-native-community/react-native-linear-gradient

There are others approaches like expo, however react-native-linear-gradient have worked better for me.

<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} style={styles.linearGradient}>
  <Text style={styles.buttonText}>
    Sign in with Facebook
  </Text>
</LinearGradient>

// Later on in your styles..
var styles = StyleSheet.create({
  linearGradient: {
    flex: 1,
    paddingLeft: 15,
    paddingRight: 15,
    borderRadius: 5
  },
  buttonText: {
    fontSize: 18,
    fontFamily: 'Gill Sans',
    textAlign: 'center',
    margin: 10,
    color: '#ffffff',
    backgroundColor: 'transparent',
  },
});

Update: Index of Nth occurance one-liner:

int NthOccurence(string s, char t, int n)
{
    s.TakeWhile(c => n - (c == t)?1:0 > 0).Count();
}

Use these at your own risk. This looks like homework, so I left a few bugs in there for your to find:

int CountChars(string s, char t)
{
   int count = 0;
   foreach (char c in s)
      if (s.Equals(t)) count ++;
   return count;
}

.

int CountChars(string s, char t)
{
     return s.Length - s.Replace(t.ToString(), "").Length;
}

.

int CountChars(string s, char t)
{
    Regex r = new Regex("[\\" + t + "]");
    return r.Match(s).Count;
}

Make sure that your .gitignore is in the root of the working directory, and in that directory run git status and copy the path to the file from the status output and paste it into the .gitignore.

If that doesn’t work, then it’s likely that your file is already tracked by Git. You can confirm this through the output of git status. If the file is not listed in the “Untracked files” section, then it is already tracked by Git and it will ignore the rule from the .gitignore file.

The reason to ignore files in Git is so that they won't be added to the repository. If you previously added a file you want to be ignored, then it will be tracked by Git and the ignore rules matching it will be skipped. Git does this since the file is already part of the repository.

In order to actually ignore the file, you have to untrack it and remove it from the repository. You can do that by using git rm --cached sites/default/settings.php. This removes the file from the repository without physically deleting the file (that’s what the --cached does). After committing that change, the file will be removed from the repository, and ignoring it should work properly.

Null pointer is a special reserved value of a pointer. A pointer of any type has such a reserved value. Formally, each specific pointer type (int *, char * etc.) has its own dedicated null-pointer value. Conceptually, when a pointer has that null value it is not pointing anywhere.

Void pointer is a specific pointer type - void * - a pointer that points to some data location in storage, which doesn't have any specific type.

So, once again, null pointer is a value, while void pointer is a type. These concepts are totally different and non-comparable. That essentially means that your question, as stated, is not exactly valid. It is like asking, for example, "What is the difference between a triangle and a car?".

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.

The initial size() of V will be 0, while int n contains any random value because you don't initialize it.

V.size() < n is probably false.

Silly me missed the "Enter the amount of numbers you want to evaluate: "

If you enter a n that's smaller than V.size() at that time, the loop will terminate.

If you have milliseconds in the date string, you can use the following.

select TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')From Dual;

And then convert it to Date with:

select trunc(TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')) From Dual;

It worked for me, hope it will help you as well.

After some tries, these are the samples I am using in order to connect:

Specifying the username and the password:

sqlcmd -S 211.11.111.111 -U NotSA -P NotTheSaPassword

Specifying the DB as well:

sqlcmd -S 211.11.111.111 -d SomeSpecificDatabase -U NotSA -P NotTheSaPassword

If you are running PHP on Apache then you can use the enviroment variable called DOCUMENT_ROOT. This means that the path is dynamic, and can be moved between servers without messing about with the code.

<?php
  $fileLocation = getenv("DOCUMENT_ROOT") . "/myfile.txt";
  $file = fopen($fileLocation,"w");
  $content = "Your text here";
  fwrite($file,$content);
  fclose($file);
?>

There's a clone snippet here, which you can add to your model which does this:

def clone(self):
  new_kwargs = dict([(fld.name, getattr(old, fld.name)) for fld in old._meta.fields if fld.name != old._meta.pk]);
  return self.__class__.objects.create(**new_kwargs)

You get this error because a class which has no constructor has a default constructor, which is argument-less and is equivalent to the following code:

public ACSubClass() {
    super();
}

However since your BaseClass declares a constructor (and therefore doesn't have the default, no-arg constructor that the compiler would otherwise provide) this is illegal - a class that extends BaseClass can't call super(); because there is not a no-argument constructor in BaseClass.

This is probably a little counter-intuitive because you might think that a subclass automatically has any constructor that the base class has.

The simplest way around this is for the base class to not declare a constructor (and thus have the default, no-arg constructor) or have a declared no-arg constructor (either by itself or alongside any other constructors). But often this approach can't be applied - because you need whatever arguments are being passed into the constructor to construct a legit instance of the class.

DisplayFor is also useful for templating. You could write a template for your Model, and do something like this:

@Html.DisplayFor(m => m)

Similar to @Html.EditorFor(m => m). It's useful for the DRY principal so that you don't have to write the same display logic over and over for the same Model.

Take a look at this blog on MVC2 templates. It's still very applicable to MVC3:

http://www.dalsoft.co.uk/blog/index.php/2010/04/26/mvc-2-templates/

It's also useful if your Model has a Data annotation. For instance, if the property on the model is decorated with the EmailAddress data annotation, DisplayFor will render it as a mailto: link.

As the new feature comes, SameSite=None cookies must also be marked as Secure or they will be rejected.

One can find more information about the change on chromium updates and on this blog post

Note: not quite related directly to the question, but might be useful for others who landed here as it was my concern at first during development of my website:

if you are seeing the warning from question that lists some 3rd party sites (in my case it was google.com, huh) - that means they need to fix it and it's nothing to do with your site. Of course unless the warning mentions your site, in which case adding Secure should fix it.

If you accidentally reset your keychain, this can occur due to missing Apple certificates in the keychain. I followed this to solve my problem.

I had the same issue and was able to fix by re-downloading the WWDR (Apple Worldwide Developer Relations Certification Authority). Download from here: http://developer.apple.com/certificationauthority/AppleWWDRCA.cer

Since jQuery 1.5 you can use the deferred objects mechanism:

$.post('some.php', {name: 'John'})
    .done(function(msg){  })
    .fail(function(xhr, status, error) {
        // error handling
    });

Another way is using .ajax:

$.ajax({
  type: "POST",
  url: "some.php",
  data: "name=John&location=Boston",
  success: function(msg){
        alert( "Data Saved: " + msg );
  },
  error: function(XMLHttpRequest, textStatus, errorThrown) {
     alert("some error");
  }
});

You can see your current session settings by querying nls_session_parameters:

select value
from nls_session_parameters
where parameter = 'NLS_NUMERIC_CHARACTERS';

VALUE                                  
----------------------------------------
.,                                       

That may differ from the database defaults, which you can see in nls_database_parameters.

In this session your query errors:

select to_number('100,12') from dual;

Error report -
SQL Error: ORA-01722: invalid number
01722. 00000 -  "invalid number"

I could alter my session, either directly with alter session or by ensuring my client is configured in a way that leads to the setting the string needs (it may be inherited from a operating system or Java locale, for example):

alter session set NLS_NUMERIC_CHARACTERS = ',.';
select to_number('100,12') from dual;

TO_NUMBER('100,12')
-------------------
             100,12 

In SQL Developer you can set your preferred value in Tool->Preferences->Database->NLS.

But I can also override that session setting as part of the query, with the optional third nlsparam parameter to to_number(); though that makes the optional second fmt parameter necessary as well, so you'd need to be able pick a suitable format:

alter session set NLS_NUMERIC_CHARACTERS = '.,';
select to_number('100,12', '99999D99', 'NLS_NUMERIC_CHARACTERS='',.''')
from dual;

TO_NUMBER('100,12','99999D99','NLS_NUMERIC_CHARACTERS='',.''')
--------------------------------------------------------------
                                                        100.12 

By default the result is still displayed with my session settings, so the decimal separator is still a period.

I don't have enough reputation to comment on the relevant answers, but to people reading this; adding .btn does not just add the pointer cursor but adds a lot of other styling as well. Which is great if it's a button and you want the bootstap button styling, but in other cases it would mess a lot up for other elements.

The best thing you can do, like Hari Das suggested, and which I also always do, is to add the following css:

.cursor-pointer {
  cursor: pointer;
}

After which you can add it to any element

<div class="cursor-pointer"> .. </div>

Keep in mind that if you're doing a cross-domain Ajax call (by using JSONP) - you can't do it synchronously, the async flag will be ignored by jQuery.

$.ajax({
    url: "testserver.php",
    dataType: 'jsonp', // jsonp
    async: false //IGNORED!!
});

For JSONP-calls you could use:

1. Ajax-call to your own domain - and do the cross-domain call server-side
2. Change your code to work asynchronously
3. Use a "function sequencer" library like Frame.js (this answer)
4. Block the UI instead of blocking the execution (this answer) (my favourite way)

There is a new open-source effort to develop a Java library for push notifications on Android, using the Meteor comet server as a backend. You can check it out at the Deacon Project Blog. We need developers, so please spread the word!

The better way to do this is creating a fake array in component:

In Component:

fakeArray = new Array(12);

InTemplate:

<ng-container *ngFor = "let n of fakeArray">
     MyCONTENT
</ng-container>

I suspect Steven A. Lowe's rolled up newspaper therapy is required for the designer of the original data structure.

As an aside, GUIDs as a primary key can be a performance hog. I wouldn't recommend it.

I do not know if it's what you were looking for, but it sounds to me something like this.

This is for linux (ubuntu) but maybe it also works on mac:

If the file is a pdf called 'book.pdf' and is located in your downloads, then

import subprocess

path='/home/user/Downloads/book.pdf'
subprocess.call(['evince', path])

where evince is the program that open pdfs in ubuntu

Step 1. Figure out which errors you want to trap:

If the table does not exist:

SQL> drop table x;
drop table x
           *
ERROR at line 1:
ORA-00942: table or view does not exist

If the table is in use:

SQL> create global temporary table t (data varchar2(4000));

Table created.

Use the table in another session. (Notice no commit or anything after the insert.)

SQL> insert into t values ('whatever');

1 row created.

Back in the first session, attempt to drop:

SQL> drop table t;
drop table t
           *
ERROR at line 1:
ORA-14452: attempt to create, alter or drop an index on temporary table already in use

So the two errors to trap:

1. ORA-00942: table or view does not exist
2. ORA-14452: attempt to create, alter or drop an index on temporary table already in use

See if the errors are predefined. They aren't. So they need to be defined like so:

create or replace procedure p as
    table_or_view_not_exist exception;
    pragma exception_init(table_or_view_not_exist, -942);
    attempted_ddl_on_in_use_GTT exception;
    pragma exception_init(attempted_ddl_on_in_use_GTT, -14452);
begin
    execute immediate 'drop table t';

    exception 
        when table_or_view_not_exist then
            dbms_output.put_line('Table t did not exist at time of drop. Continuing....');

        when attempted_ddl_on_in_use_GTT then
            dbms_output.put_line('Help!!!! Someone is keeping from doing my job!');
            dbms_output.put_line('Please rescue me');
            raise;
end p;

And results, first without t:

SQL> drop table t;

Table dropped.

SQL> exec p;
Table t did not exist at time of drop. Continuing....

PL/SQL procedure successfully completed.

And now, with t in use:

SQL> create global temporary table t (data varchar2(4000));

Table created.

In another session:

SQL> insert into t values (null);

1 row created.

And then in the first session:

SQL> exec p;
Help!!!! Someone is keeping from doing my job!
Please rescue me
BEGIN p; END;

*
ERROR at line 1:
ORA-14452: attempt to create, alter or drop an index on temporary table already in use
ORA-06512: at "SCHEMA_NAME.P", line 16
ORA-06512: at line 1

This Should Work:

import glob
extensions = ('*.txt', '*.mdown', '*.markdown')
for i in extensions:
    for files in glob.glob(i):
        print (files)

YES you can!! The solution should be easy, safe, and performant...

I'm new to postgresql, but it seems you can create computed columns by using an expression index, paired with a view (the view is optional, but makes makes life a bit easier).

Suppose my computation is md5(some_string_field), then I create the index as:

CREATE INDEX some_string_field_md5_index ON some_table(MD5(some_string_field));

Now, any queries that act on MD5(some_string_field) will use the index rather than computing it from scratch. For example:

SELECT MAX(some_field) FROM some_table GROUP BY MD5(some_string_field);

You can check this with explain.

However at this point you are relying on users of the table knowing exactly how to construct the column. To make life easier, you can create a VIEW onto an augmented version of the original table, adding in the computed value as a new column:

CREATE VIEW some_table_augmented AS 
   SELECT *, MD5(some_string_field) as some_string_field_md5 from some_table;

Now any queries using some_table_augmented will be able to use some_string_field_md5 without worrying about how it works..they just get good performance. The view doesn't copy any data from the original table, so it is good memory-wise as well as performance-wise. Note however that you can't update/insert into a view, only into the source table, but if you really want, I believe you can redirect inserts and updates to the source table using rules (I could be wrong on that last point as I've never tried it myself).

Edit: it seems if the query involves competing indices, the planner engine may sometimes not use the expression-index at all. The choice seems to be data dependant.

There is another consistent way (only for IE9+) in vanilla JavaScript for this:

const iframe = document.getElementById('iframe');
const handleLoad = () => console.log('loaded');

iframe.addEventListener('load', handleLoad, true)

And if you're interested in Observables this does the trick:

return Observable.fromEventPattern(
  handler => iframe.addEventListener('load', handler, true),
  handler => iframe.removeEventListener('load', handler)
);

Have you ever tried Genymotion? I've read about it last week and it is great. They have several Android Images that you run (with their own software). The images are INCREDIBLY fast and they have Google Play installed on them. Check it out if it is the kind of thing that you need.

Follow these steps:

1. Add the Action Bar instance in the Java Code final ActionBar actionBar = getActionBar();
2. Enable the Home Display Option actionBar.setDisplayShowHomeEnabled(false);
3. Add the following code in the respective activity's manifest file android:logo=@drawable/logo and android:label="@string/actionbar_text"

I think this will help you

The principle of subqueries is not at all bad, but I don't think that you should use it in your example. If I understand correctly you want to get the maximum score for each date. In this case you should use a GROUP BY.

Websocket VS SSE

Web Sockets - It is a protocol which provides a full-duplex communication channel over a single TCP connection. For instance a two-way communication between the Server and Browser Since the protocol is more complicated, the server and the browser has to rely on library of websocket which is socket.io

Example - Online chat application.

SSE(Server-Sent Event) - In case of server sent event the communication is carried out from server to browser only and browser cannot send any data to the server. This kind of communication is mainly used when the need is only to show the updated data, then the server sends the message whenever the data gets updated. For instance a one-way communication between the Server to Browser. This protocol is less complicated, so no need to rely on the external library JAVASCRIPT itself provides the EventSource interface to receive the server sent messages.

Example - Online stock quotes or cricket score website.

You can do this with a string datatype. Use the PadLeft method:

var myString = "1";
myString = myString.PadLeft(myString.Length + 5, '0');

000001

You need to use

 $rootScope.$broadcast()

in the controller that must send datas. And in the one that receive those datas, you use

 $scope.$on

I too had that same problem.. If we think logically little bit we can get the answer.. It worked for me very well.. I hope u will get it..

1. listviewdemo.xml

   <ListView
       android:id="@+id/listview"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingBottom="30dp"
       android:paddingLeft="10dp"
       android:paddingRight="10dp" />
   

2. listviewcontent.xml - note that TextView - android:id="@+id/txtLstItem"

   <LinearLayout
       android:id="@+id/listviewcontentlayout"
       android:layout_width="0dp"
       android:layout_height="fill_parent"
       android:layout_weight="1"
       android:orientation="horizontal">
   
       <ImageView
           android:id="@+id/img1"
           android:layout_width="wrap_content"

               android:gravity="left"
               android:shadowColor="@android:color/black"
               android:shadowRadius="5"
               android:textColor="@android:color/white" />

       <ImageView

           android:layout_height="wrap_content"
           android:layout_marginRight="6dp" />
   </LinearLayout>
   

3. ListViewActivity.java - Note that view.findViewById(R.id.txtLstItem) - as we setting the value to TextView by setText() method we getting text from TextView by View object returned by onItemClick method. OnItemClick() returns the current view.

   TextView v=(TextView) view.findViewById(R.id.txtLstItem);
   Toast.makeText(getApplicationContext(), "selected Item Name is "+v.getText(), Toast.LENGTH_LONG).show();**
   

   Using this simple logic we can get other values like CheckBox, RadioButton, ImageView etc.

   ListView List = (ListView) findViewById(R.id.listview);
   cursor = cr.query(CONTENT_URI,projection,null,null,null);
   adapter = new ListViewCursorAdapter(ListViewActivity.this, R.layout.listviewcontent, cursor, from, to);
   
   cursor.moveToFirst();
   
   // Let activity manage the cursor
   startManagingCursor(cursor);
   
   List.setAdapter(adapter);
   List.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick (AdapterView < ? > adapter, View view,int position, long arg){
               // TODO Auto-generated method stub
               TextView v = (TextView) view.findViewById(R.id.txtLstItem);
               Toast.makeText(getApplicationContext(), "selected Item Name is " + v.getText(), Toast.LENGTH_LONG).show();
           }
       }
   );
   

I might have a simple answer for the question without extending the TextView and implementing a long code.

Code :

 TextView tv = (TextView) findViewById(R.id.textview1);
    tv.setTypeface(Typeface.createFromAsset(getAssets(), "font.ttf"));

Place the custom font file in assets folder as usual and try this. It works for me. I just dont understand why peter has given such a huge code for this simple thing or he has given his answer in old version.

MYSQL 8 does, in a way:

MYSQL 8 supports JSON tables, so you could load your results into a JSON variable and select from that variable using the JSON_TABLE() command.

The syntax you used is problematic. In html, an attribute (ex: style) has a value delimited by double quotes. In that case, the value of the style attribute is a css list of selectors. Try this:

<h2 style="text-align:center; font-family:tahoma">TITLE</h2>

• node-mysql — A node.js module implementing the MySQL protocol
• node-mysql2 — Yet another pure JS async driver. Pipelining, prepared statements.
• node-mysql-libmysqlclient — MySQL asynchronous bindings based on libmysqlclient

node-mysql looks simple enough:

var mysql      = require('mysql');

  user     : 'bob',
  password : 'secret',

connection.connect(function(err) {

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

As @Brian Riley already said you should either remove 1 column in your select

from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language
order by sum(country.population*countrylanguage.percentage) desc ;

or add it to your grouping

select countrylanguage.language, country.code, sum(country.population*countrylanguage.percentage/100)
from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language, country.code
order by sum(country.population*countrylanguage.percentage) desc ;

My issue was , I tried with IP rather than public DNS. Then i tried with public DNS and its resolved

WebSockets are implemented with a protocol that involves handshake between client and server. I don't imagine they work very much like normal sockets. Read up on the protocol, and get your application to talk it. Alternatively, use an existing WebSocket library, or .Net4.5beta which has a WebSocket API.

CSS?

td {
  padding-top: 2px;
  padding-bottom: 2px;
}

Since nobody referred to the official (angular-cli team) story on how to include Bootstrap yet: https://github.com/angular/angular-cli/wiki/stories-include-bootstrap

Include Bootstrap

Bootstrap is a popular CSS framework which can be used within an Angular project. This guide will walk you through adding bootstrap to your Angular CLI project and configuring it to use bootstrap.

Using CSS

Getting Started

Create a new project and navigate into the project

ng new my-app
cd my-app

Installing Bootstrap

With the new project created and ready you will next need to install bootstrap to your project as a dependency. Using the --save option the dependency will be saved in package.json

# version 3.x
npm install bootstrap --save

# version 4.x
npm install bootstrap@next --save

Configuring Project

Now that the project is set up it must be configured to include the bootstrap CSS.

• Open the file .angular-cli.json from the root of your project.
• Under the property apps the first item in that array is the default application.
• There is a property styles which allows external global styles to be applied to your application.
• Specify the path to bootstrap.min.css

It should look like the following when you are done:

"styles": [
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "styles.css"
      ],

Note: When you make changes to .angular-cli.json you will need to re-start ng serve to pick up configuration changes.

Testing Project

Open app.component.html and add the following markup:

<button class="btn btn-primary">Test Button</button>

With the application configured, run ng serve to run your application in develop mode. In your browser navigate to the application localhost:4200. Verify the bootstrap styled button appears.

Using SASS

Getting Started

Create a new project and navigate into the project

ng new my-app --style=scss
cd my-app

Installing Bootstrap

# version 3.x
npm install bootstrap-sass --save

# version 4.x
npm install bootstrap@next --save

Configuring Project

Create an empty file _variables.scss in src/.

If you are using bootstrap-sass, add the following to _variables.scss:

$icon-font-path: '../node_modules/bootstrap-sass/assets/fonts/bootstrap/';

In styles.scss add the following:

// version 3
@import 'variables';
@import '../node_modules/bootstrap-sass/assets/stylesheets/_bootstrap';

// version 4
@import 'variables';
@import '../node_modules/bootstrap/scss/bootstrap';

Testing Project

Open app.component.html and add the following markup:

<button class="btn btn-primary">Test Button</button>

With the application configured, run ng serve to run your application in develop mode. In your browser navigate to the application localhost:4200. Verify the bootstrap styled button appears. To ensure your variables are used open _variables.scss and add the following:

$brand-primary: red;

Return the browser to see the font color changed.

I know this is a fairly old thread, but thought I might put in my two cents for those who find it useful.

The script (apologies about the uncreative method names):

window.Listener = {
    _Active: [],
    remove: function(attached, on, callback, capture){
        for(var i = 0; i < this._Active.length; i++){
            var current = this._Active[i];
            if(current[0] === attached && current[1] === on && current[2] === callback){
                attached.removeEventListener(on, callback, (capture || false));
                return this._Active.splice(i, 1);
            }
        }
    }, removeAtIndex(i){
        if(this._Active[i]){
            var remove = this._Active[i];
            var attached = remove[0], on = remove[1], callback = remove[2];
            attached.removeEventListener(on, callback, false);
            return this._Active.splice(i, 1);
        }
    }, purge: function(){
        for(var i = 0; i < this._Active.length; i++){
            var current = this._Active[i];
            current[0].removeEventListener(current[1], current[2]);
            this._Active.splice(i, 1);
        }
    }, declare: function(attached, on, callback, capture){
        attached.addEventListener(on, callback, (capture || false));
        if(this._Active.push([attached, on, callback])){
            return this._Active.length - 1;
        }
    }
};

And you can use it like so:

// declare a new onclick listener attached to the document
var clickListener = Listener.declare(document, "click" function(e){
    // on click, remove the listener and log the clicked element
    console.log(e.target);
    Listener.removeAtIndex(clickListener);
});

// completely remove all active listeners 
// (at least, ones declared via the Listener object)
Listener.purge();

// works exactly like removeEventListener
Listener.remove(element, on, callback);

From your question it seems like you are using C99, as you have used %lf for double.

To achieve the desired output replace:

sprintf(aa, "%lf", a);

with

sprintf(aa, "%0.7f", a);

The general syntax "%A.B" means to use B digits after decimal point. The meaning of the A is more complicated, but can be read about here.

Read carefully about the reason.

"Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/maven-metadata.xml in local"

So all you need to do is download the maven-metadata.xml to your {HOME}.m2\repository

That's it.

@article = user.articles.build(:title => "MainTitle")
@article.save

There is no language level support for this in MySQL. Here is a work-around involving MySQL information_schema meta-data in 5.0+, but it won't address your issue in 4.0.18.

drop procedure if exists schema_change;

delimiter ';;'
create procedure schema_change() begin

    /* delete columns if they exist */
    if exists (select * from information_schema.columns where table_schema = schema() and table_name = 'table1' and column_name = 'column1') then
        alter table table1 drop column `column1`;
    end if;
    if exists (select * from information_schema.columns where table_schema = schema() and table_name = 'table1' and column_name = 'column2') then
        alter table table1 drop column `column2`;
    end if;

    /* add columns */
    alter table table1 add column `column1` varchar(255) NULL;
    alter table table1 add column `column2` varchar(255) NULL;

end;;

delimiter ';'
call schema_change();

drop procedure if exists schema_change;

I wrote some more detailed information in a blog post.

Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):

Sub Module for Connecting to MS SQL with Remote Host & Username/Password

Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String

'Setup the connection string for accessing MS SQL database
   'Make sure to change:
       '1: PASSWORD
       '2: USERNAME
       '3: REMOTE_IP_ADDRESS
       '4: DATABASE
    ConnectionString = "Provider=SQLOLEDB.1;Password=PASSWORD;Persist Security Info=True;User ID=USERNAME;Data Source=REMOTE_IP_ADDRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=DATABASE"

    'Opens connection to the database
    cnn.Open ConnectionString
    'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
    cnn.CommandTimeout = 900

    'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
    StrQuery = "SELECT TOP 10 * FROM tbl_table"

    'Performs the actual query
    rst.Open StrQuery, cnn
    'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook
    Sheets(1).Range("A2").CopyFromRecordset rst
End Sub

You can use the Element.scrollTo() method.

It can be animated using the built-in browser/OS animation, so it's super smooth.

function scrollToBottom() {
    const scrollContainer = document.getElementById('container');
    scrollContainer.scrollTo({
        top: scrollContainer.scrollHeight,
        left: 0,
        behavior: 'smooth'
    });
}

// initialize dummy content
const scrollContainer = document.getElementById('container');
const numCards = 100;
let contentInnerHtml = '';
for (let i=0; i<numCards; i++) {
  contentInnerHtml += `<div class="card mb-2"><div class="card-body">Card ${i + 1}</div></div>`;
}
scrollContainer.innerHTML = contentInnerHtml;

.overflow-y-scroll {
  overflow-y: scroll;
}

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>

<div class="d-flex flex-column vh-100">
  <div id="container" class="overflow-y-scroll flex-grow-1"></div>
  <div>
    <button class="btn btn-primary" onclick="scrollToBottom()">Scroll to bottom</button>
  </div>
</div>

I had this problem. For posterity, my exception was:

org.xml.sax.SAXParseException; lineNumber: 7; columnNumber: 117;
schema_reference.4: Failed to read schema document
'http://www.springframework.org/schema/beans/spring-beans-4.2.xsd'

I solved it when I realised the the version of spring-beans specified in my Maven pom.xml was 4.1.x, thus meaning the specific .xsd could not be found on the classpath.

This was masked for a long time because I normally am online, so I thought being offline had "broken" the build. But it really had nothing to do with it. Updating my pom.xml to specify the correct version of spring-beans, namely 4.2.x, fixed it.

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

Generally speaking, the cli/php.ini file is used when the PHP binary is called from the command-line.
You can check that running php --ini from the command-line.

fpm/php.ini will be used when PHP is run as FPM -- which is the case with an nginx installation.
And you can check that calling phpinfo() from a php page served by your webserver.

cgi/php.ini, in your situation, will most likely not be used.

Using two distinct php.ini files (one for CLI, and the other one to serve pages from your webserver) is done quite often, and has one main advantages : it allows you to have different configuration values in each case.

Typically, in the php.ini file that's used by the web-server, you'll specify a rather short max_execution_time : web pages should be served fast, and if a page needs more than a few dozen seconds (30 seconds, by default), it's probably because of a bug -- and the page's generation should be stopped.
On the other hand, you can have pretty long scripts launched from your crontab (or by hand), which means the php.ini file that will be used is the one in cli/. For those scripts, you'll specify a much longer max_execution_time in cli/php.ini than you did in fpm/php.ini.

max_execution_time is a common example ; you could do the same with several other configuration directives, of course.

I respectually disagree with the notion that link extension methods should be side-effect free (not only because they aren't, any delegate can perform side effects).

Consider the following:

   public class Element {}

   public Enum ProcessType
   {
      This = 0, That = 1, SomethingElse = 2
   }

   public class Class1
   {
      private Dictionary<ProcessType, Action<Element>> actions = 
         new Dictionary<ProcessType,Action<Element>>();

      public Class1()
      {
         actions.Add( ProcessType.This, DoThis );
         actions.Add( ProcessType.That, DoThat );
         actions.Add( ProcessType.SomethingElse, DoSomethingElse );
      }

      // Element actions:

      // This example defines 3 distict actions
      // that can be applied to individual elements,
      // But for the sake of the argument, make
      // no assumption about how many distict
      // actions there may, and that there could
      // possibly be many more.

      public void DoThis( Element element )
      {
         // Do something to element
      }

      public void DoThat( Element element )
      {
         // Do something to element
      }

      public void DoSomethingElse( Element element )
      {
         // Do something to element
      }

      public void Apply( ProcessType processType, IEnumerable<Element> elements )
      {
         Action<Element> action = null;
         if( ! actions.TryGetValue( processType, out action ) )
            throw new ArgumentException("processType");
         foreach( element in elements ) 
            action(element);
      }
   }

What the example shows is really just a kind of late-binding that allows one invoke one of many possible actions having side-effects on a sequence of elements, without having to write a big switch construct to decode the value that defines the action and translate it into its corresponding method.

In my case, I needed a simple replacing of unique keys with names, so I thought this up:

a = 'This is a test string.'
b = {'i': 'I', 's': 'S'}
for x,y in b.items():
    a = a.replace(x, y)
>>> a
'ThIS IS a teSt StrIng.'

Use the timestamp you get by calling valueOf on the date object:

var diff = date2.valueOf() - date1.valueOf();
var diffInHours = diff/1000/60/60; // Convert milliseconds to hours

The easiest way to get to know it for your compiler/platform:

#include <iostream>

int main() {
  std::cout << sizeof(long)*8 << std::endl;
}

Themultiplication by 8 is to get bits from bytes.

When you need a particular size, it is often easiest to use one of the predefined types of a library. If that is undesirable, you can do what often happens with autoconf software and have the configuration system determine the right type for the needed size.

In one of the comments, you say:

Somehow I got an Nonetype value, it supposed to be an int, but it's now a Nonetype object

If it's your code, figure out how you're getting None when you expect a number and stop that from happening.

If it's someone else's code, find out the conditions under which it gives None and determine a sensible value to use for that, with the usual conditional code:

result = could_return_none(x)

if result is None:
    result = DEFAULT_VALUE

...or even...

if x == THING_THAT_RESULTS_IN_NONE:
    result = DEFAULT_VALUE
else:
    result = could_return_none(x) # But it won't return None, because we've restricted the domain.

There's no reason to automatically use 0 here — solutions that depend on the "false"-ness of None assume you will want this. The DEFAULT_VALUE (if it even exists) completely depends on your code's purpose.

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

Q:Can't bind to 'pSelectableRow' since it isn't a known property of 'tr'.

A:you need to configure the primeng tabulemodule in ngmodule

this work with me

File file = ..... // Save file

context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file)));

If you mean how to remove the 'checked' state from all checkboxes:

$('input:checkbox').removeAttr('checked');

In fact, your query is right except for the typo: your filter is excluding all records: you should change the <= for >= and vice versa:

qry = DBSession.query(User).filter(
        and_(User.birthday <= '1988-01-17', User.birthday >= '1985-01-17'))
# or same:
qry = DBSession.query(User).filter(User.birthday <= '1988-01-17').\
        filter(User.birthday >= '1985-01-17')

Also you can use between:

qry = DBSession.query(User).filter(User.birthday.between('1985-01-17', '1988-01-17'))

It means the path you input caused an error. In your LD_PRELOAD command, modify the path like the error tips:

/usr/lib/liblunar-calendar-preload.so

Look here: http://en.cppreference.com/w/cpp/algorithm/sort.

It says:

template< class RandomIt, class Compare >
void sort( RandomIt first, RandomIt last, Compare comp );

• comp - comparison function which returns ?true if the first argument is less than the second. The signature of the comparison function should be equivalent to the following: bool cmp(const Type1 &a, const Type2 &b);

Also, here's an example of how you can use std::sort using a custom C++14 polymorphic lambda:

std::sort(std::begin(container), std::end(container),
          [] (const auto& lhs, const auto& rhs) {
    return lhs.first < rhs.first;
});

Or just use Control.SuspendLayout() and Control.ResumeLayout().

A straightforward way to do this with no extra tools is to export the registry to a text file before the install, then export it to another file after. Then, compare the two files.

Having said that, the Sysinternals tools are great for this.

Like others mentioned in this thread, replacing the entire body HTML is a bad idea because it reinserts the entire DOM and can potentially break any other javascript that was acting on those elements.

Instead, replace just the text on your page and not the DOM elements themselves using jQuery filter:

  $('body :not(script)').contents().filter(function() {
    return this.nodeType === 3;
  }).replaceWith(function() {
      return this.nodeValue.replace('-9o0-9909','The new string');
  });

this.nodeType is the type of node we are looking to replace the contents of. nodeType 3 is text. See the full list here.

OK I just solved it. In the last import I added a ";" by copying other code examples. I guess it's the standard line ending that is required.

So

<%@ page import="java.util.*" %>
<%@ page import="org.eresearch.knowledgeportal.dao.CategoryDao" %>
<%@ page import="org.eresearch.knowledgeportal.model.Category" %>

became

 <%@ page import="java.util.*" %>
 <%@ page import="org.eresearch.knowledgeportal.dao.CategoryDao" %>
 <%@ page import="org.eresearch.knowledgeportal.model.Category;" %>

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

Just an update to the answer of @rafa.pereira. Since ggplot2 is part of tidyverse, it makes sense to use the convenient tidyverse functions to get rid of NAs.

library(tidyverse)
airquality %>% 
        drop_na(Ozone) %>%
        ggplot(aes(x = Ozone))+
        geom_bar(stat="bin")

Note that you can also use drop_na() without columns specification; then all the rows with NAs in any column will be removed.

You should've kept that DOM ready function

$(function() {
    $("#projectKey").change(function() {
        alert( $('option:selected', this).text() );
    });
});

The document isn't ready if you added the javascript before the elements in the DOM, you have to either use a DOM ready function or add the javascript after the elements, the usual place is right before the </body> tag

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

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

This is in case when you dont use AJAX to load your div

Order Collection Limit :

$orderCollection = Mage::getResourceModel('sales/order_collection'); 
$orderCollection->getSelect()->limit(10);

foreach ($orderCollection->getItems() as $order) :
   $orderModel = Mage::getModel('sales/order');
   $order =   $orderModel->load($order['entity_id']);
   echo $order->getId().'<br>'; 
endforeach; 

In case you don't want to use the M2_HOME and want to direct the IntelliJ to the maven installation you can simply set it by:

• goto File => Setting => Maven => Maven home directory
• point to your maven build directory e.g. /usr/local/maven/apache-maven-3.0.4

A better way is to have a symlink e.g. 'latest' for the latest version and point your IntelliJ to use that for consistency, given latest points to the latest version of maven installed on your box.

Use:

Function fNbrStrInStr(strin As Variant, strToCount As String)
    fNbrStrInStr = UBound(Split(strin, strToCount)) - LBound(Split(strin, strToCount))
End Function

I used strin as variant to handle very long text. The split can be zero-based or one-based for low end depending on user settings, and subtracting it ensures the correct count.

I did not include a test for strcount being longer than strin to keep code concise.

You can use VBA - something like

Range("A1:A6").Interior.Color = RGB(127,187,199)

Just pass in the cell value.

Here are two ways to pass value from Gradle to use in Java;

Generate Java Constants

android {
    buildTypes {
        debug {
            buildConfigField "int", "FOO", "42"
            buildConfigField "String", "FOO_STRING", "\"foo\""
            buildConfigField "boolean", "LOG", "true"
        }

        release {
            buildConfigField "int", "FOO", "52"
            buildConfigField "String", "FOO_STRING", "\"bar\""
            buildConfigField "boolean", "LOG", "false"
        }
    }
}

You can access them with BuildConfig.FOO

Generate Android resources

android {
    buildTypes {
        debug{
            resValue "string", "app_name", "My App Name Debug"
        }
        release {
            resValue "string", "app_name", "My App Name"
        }
    }
}

You can access them in the usual way with @string/app_name or R.string.app_name

filter expects to get a function and something that it can iterate over. The function should return True or False for each element in the iterable. In your particular example, what you're looking to do is something like the following:

In [47]: def greetings(x):
   ....:     return x == "hello"
   ....:

In [48]: filter(greetings, ["hello", "goodbye"])
Out[48]: ['hello']

Note that in Python 3, it may be necessary to use list(filter(greetings, ["hello", "goodbye"])) to get this same result.

EL expression:

${requestScope.Error_Message}

There are several implicit objects in JSP EL. See Expression Language under the "Implicit Objects" heading.

For everybody who uses Rider you have to select your project>Right Click>Properties>Configurations Then select Debug and Release and check "Allow unsafe code" for both.

repeat() {
    # $1=number of patterns to repeat
    # $2=pattern
    printf -v "TEMP" '%*s' "$1"
    echo ${TEMP// /$2}
}

If you will not be needing the _id of the records I will recommend unsetting it when querying the DB which will enable you to print the returned records directly e.g

To unset the _id when querying and then print data in a loop you write something like this

records = mycollection.find(query, {'_id': 0}) #second argument {'_id':0} unsets the id from the query
for record in records:
    print(record)
