Use Keystore Explorer gui - http://keystore-explorer.sourceforge.net/ - allows you to extract the private key from a .jks in various formats.

you can use commons csv to convert into CSV format. or use POI to convert into xls. if you need helper to convert into xls, you can use jxls, it can convert java bean (or list) into excel with expression language.

Basically, the json doc maybe is a json array, right? so it will be same. the result will be list, and you just write the property that you want to display in excel format that will be read by jxls. See http://jxls.sourceforge.net/reference/collections.html

If the problem is the json can't be read in the jxls excel property, just serialize it into collection of java bean first.

The Tag is just used to easily find your output, because the Output of LogCat can be sometimes very long. You can define somewhere in your class:

private static final String TAG = "myApp";

and use it when debugging

Log.v(TAG, "did something");

You can apply as well a Filter to only search for the tag.

Here is one example that worked for me.

find <mainfolder path> -name '*myfiles.java' | xargs -n 1 basename

You can try use simple command line. bcdedit is what you need, just run cmd as administrator and type bcdedit or bcdedit \v, this doesn't work on XP, but hope it is not an issue.

Anyway for XP you can take a look into boot.ini file.

I think that this construct: if exists (select... is specific for MS SQL. In MySQL EXISTS predicate tells you whether the subquery finds any rows and it's used like this: SELECT column1 FROM t1 WHERE EXISTS (SELECT * FROM t2);

You can rewrite the above lines of code like this:

DELIMITER $$

CREATE PROCEDURE `checando`(in nombrecillo varchar(30), in contrilla varchar(30), out resultado int)

BEGIN
    DECLARE count_prim INT;
    DECLARE count_sec INT;

    SELECT COUNT(*) INTO count_prim FROM compas WHERE nombre = nombrecillo AND contrasenia = contrilla;
    SELECT COUNT(*) INTO count_sec FROM FROM compas WHERE nombre = nombrecillo;

    if (count_prim > 0) then
        set resultado = 0;
    elseif (count_sec > 0) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
    SELECT resultado;
END

Above Solution by @arcain Plus below steps solved me the issue

1. Modifying the "package sources" under Nuget package manger settings to check the checkbox to use the nuget.org settings resolved my issue.

2. I did also changed to use that(nuget.org) as the first choice of package source
   I did uncheck my company package sources to ensure the nuget was always picked up from global sources.

There are two ways to achieve that:

• Use -rpath linker option:

gcc XXX.c -o xxx.out -L$HOME/.usr/lib -lXX -Wl,-rpath=/home/user/.usr/lib

• Use LD_LIBRARY_PATH environment variable - put this line in your ~/.bashrc file:

  export LD_LIBRARY_PATH=/home/user/.usr/lib

This will work even for a pre-generated binaries, so you can for example download some packages from the debian.org, unpack the binaries and shared libraries into your home directory, and launch them without recompiling.

For a quick test, you can also do (in bash at least):

LD_LIBRARY_PATH=/home/user/.usr/lib ./xxx.out

which has the advantage of not changing your library path for everything else.

Ok, I will give a small example on how to do what you ask

public class ClassB extends Activity
{

 ClassA A1 = new ClassA(this); // for activity context

 ClassA A2 = new ClassA(getApplicationContext());  // for application context. 

}

For git 1.7.x the following commands worked for me:

git mv css/iphone.css css/mobile.css
git commit -m 'Rename folder.' 

There was no need for git add, since the original file (i.e. css/mobile.css) was already in the committed files previously.

What helped me is to create a symbolic link:

sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib64

You can also specify the range with the coord_cartesian command to set the y-axis range that you want, an like in the previous post use scales = free_x

p <- ggplot(plot, aes(x = pred, y = value)) +
     geom_point(size = 2.5) +
     theme_bw()+
     coord_cartesian(ylim = c(-20, 80))
p <- p + facet_wrap(~variable, scales = "free_x")
p

Basically, if you're on a 64-bit machine, IIS 7 is not (by default) serving 32-bit apps, which the database engine operates on. So here is exactly what you do:

1) ensure that the 2007 database engine is installed, this can be downloaded at: http://www.microsoft.com/downloads/details.aspx?FamilyID=7554F536-8C28-4598-9B72-EF94E038C891&displaylang=en

2) open IIS7 manager, and open the Application Pools area. On the right sidebar, you will see an option that says "Set application pool defaults". Click it, and a window will pop up with the options.

3) the second field down, which says 'Enable 32-bit applications' is probably set to FALSE by default. Simply click where it says 'false' to change it to 'true'.

4) Restart your app pool (you can do this by hitting RECYCLE instead of STOP then START, which will also work).

5) done, and your error message will go away.

There is one more way to achieve it:-

Private Sub UserForm_Initialize()
Dim list As Object
Set list = UserForm1.Controls.Add("Forms.ListBox.1", "hello", True)
With list
    .Top = 30
    .Left = 30
    .Width = 200
    .Height = 340
    .ColumnHeads = True
    .ColumnCount = 2
    .ColumnWidths = "100;100"
    .MultiSelect = fmMultiSelectExtended
    .RowSource = "Sheet1!C4:D25"
End With End Sub

Here, I am using the range C4:D25 as source of data for the columns. It will result in both the columns populated with values.

The properties are self explanatory. You can explore other options by drawing ListBox in UserForm and using "Properties Window (F4)" to play with the option values.

There's an interesting way which this can be achieved by using jQuery animate method in a unique way, where you call the animate method on a javascript Object which describes the from value and then you pass as the first parameter another js object which describes the to value, and a step function which handles each step of the animation according to the values described earlier.

Example - Animate transform translateY:

var $elm = $('h1'); // element to be moved_x000D_
_x000D_
function run( v ){_x000D_
  // clone the array (before "animate()" modifies it), and reverse it_x000D_
  var reversed = JSON.parse(JSON.stringify(v)).reverse();_x000D_
  _x000D_
  $(v[0]).animate(v[1], {_x000D_
      duration: 500,_x000D_
      step: function(val) {_x000D_
          $elm.css("transform", `translateY(${val}px)`); _x000D_
      },_x000D_
      done: function(){_x000D_
          run( reversed )_x000D_
      }_x000D_
  })_x000D_
};_x000D_
_x000D_
// "y" is arbitrary used as the key name _x000D_
run( [{y:0}, {y:80}] )

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<h1>jQuery animate <pre>transform:translateY()</pre></h1>

Remember that there is a difference between whether the query works and whether it works efficiently! A LINQ statement gets converted to T-SQL when the target of the statement is SQL Server, so you need to think about the T-SQL that would be produced.

Using String.Equals will most likely (I am guessing) bring back all of the rows from SQL Server and then do the comparison in .NET, because it is a .NET expression that cannot be translated into T-SQL.

In other words using an expression will increase your data access and remove your ability to make use of indexes. It will work on small tables and you won't notice the difference. On a large table it could perform very badly.

That's one of the problems that exists with LINQ; people no longer think about how the statements they write will be fulfilled.

In this case there isn't a way to do what you want without using an expression - not even in T-SQL. Therefore you may not be able to do this more efficiently. Even the T-SQL answer given above (using variables with collation) will most likely result in indexes being ignored, but if it is a big table then it is worth running the statement and looking at the execution plan to see if an index was used.

You don't have to save and restore the state by yourself anymore. If you set unique ID in xml and recyclerView.setSaveEnabled(true) (true by default) system will automatically do it. Here is more about this: http://trickyandroid.com/saving-android-view-state-correctly/

updatepanel issue.

My issue was due to the updatepanel placement. I had the entire modal in the updatepanel. If you declare the modal outside the updatepanel and just have say, the modal body, in the update panel, then the $('#myModalID').modal('hide'); worked.

This is the code to select value from the drop down

The value for selectlocator will be the xpath or name of dropdown box, and for optionLocator will have the value to be selected from the dropdown box.

public static boolean select(final String selectLocator,
        final String optionLocator) {
    try {
        element(selectLocator).clear();
        element(selectLocator).sendKeys(Keys.PAGE_UP);
        for (int k = 0; k <= new Select(element(selectLocator))
                .getOptions().size() - 1; k++) {
            combo1.add(element(selectLocator).getValue());
            element(selectLocator).sendKeys(Keys.ARROW_DOWN);
        }
        if (combo1.contains(optionLocator)) {
            element(selectLocator).clear();
            new Select(element(selectLocator)).selectByValue(optionLocator);
            combocheck = element(selectLocator).getValue();
            combo = "";

            return true;
        } else {
            element(selectLocator).clear();
            combo = "The Value " + optionLocator
                    + " Does Not Exist In The Combobox";
            return false;
        }
    } catch (Exception e) {
        e.printStackTrace();
        errorcontrol.add(e.getMessage());
        return false;
    }
}



private static RenderedWebElement element(final String locator) {
    try {

        return (RenderedWebElement) drivers.findElement(by(locator));
    } catch (Exception e) {
        errorcontrol.add(e.getMessage());
        return (RenderedWebElement) drivers.findElement(by(locator));
    }
}

As You're getting values from textfield as jTextField3.getText();.

As it is a textField it will return you string format as its format says:

String getText()

      Returns the text contained in this TextComponent.

So, convert your String to Integer as:

int jml = Integer.parseInt(jTextField3.getText());

instead of directly setting

   int jml = jTextField3.getText();

This while else statement should only execute the else code when the condition is false, this means it will always execute it. But, there is a catch, when you use the break keyword within the while loop, the else statement should not execute.

The code that satisfies does condition is only:

boolean entered = false;
while (condition) {
   entered = true; // Set it to true stright away
   // While loop code


   // If you want to break out of this loop
   if (condition) {
      entered = false;
      break;
   }
} if (!entered) {
   // else code
}

just for additional info, If your apps is automatically run on emulator, right click on the project, Run As -> Run Configuration, then on the Run Configuration choose on the Manual. after that, if you run your apps you will be prompted to chose where you want to run your apps, there will be listed all the available device and emulator.

There's no "guaranteed to work anywhere" method.

Step 1 is to check argv[0], if the program was started by its full path, this would (usually) have the full path. If it was started by a relative path, the same holds (though this requires getting teh current working directory, using getcwd().

Step 2, if none of the above holds, is to get the name of the program, then get the name of the program from argv[0], then get the user's PATH from the environment and go through that to see if there's a suitable executable binary with the same name.

Note that argv[0] is set by the process that execs the program, so it is not 100% reliable.

an SQL that shows SQL commands, need to run to duplicate a database from one database to another. for each table there is create a table statement and an insert statement. it assumes both databases are on the same server:

select @fromdb:="crm";
select @todb:="crmen";

SET group_concat_max_len=100000000;


SELECT  GROUP_CONCAT( concat("CREATE TABLE `",@todb,"`.`",table_name,"` LIKE `",@fromdb,"`.`",table_name,"`;\n",
"INSERT INTO `",@todb,"`.`",table_name,"` SELECT * FROM `",@fromdb,"`.`",table_name,"`;") 

SEPARATOR '\n\n')

as sqlstatement
 FROM information_schema.tables where table_schema=@fromdb and TABLE_TYPE='BASE TABLE';

Here is a snippet from me in testing... obviously passing via get to the script may not be the best... should post or just send an id and grab guid from db... anyhow.. this worked. I take the URL and convert it to a path.

// Initialize a file URL to the variable
$file = $_GET['url'];
$file = str_replace(Polepluginforrvms_Plugin::$install_url, $DOC_ROOT.'/pole-permitter/', $file );

$quoted = sprintf('"%s"', addcslashes(basename($file), '"\\'));
$size   = filesize($file);

header( "Content-type: application/octet-stream" );
header( "Content-Disposition: attachment; filename={$quoted}" );
header( "Content-length: " . $size );
header( "Pragma: no-cache" );
header( "Expires: 0" );
readfile( "{$file}" );

Others have pointed out the error in your existing code, but I'd like to take two steps further. Firstly, assuming you're using Java 1.5+, you can achieve greater readability using the enhanced for loop:

Customer findCustomerByid(int id){    
    for (Customer customer : customers) {
        if (customer.getId() == id) {
            return customer;
        }
    }
    return null; 
}

This has also removed the micro-optimisation of returning null before looping - I doubt that you'll get any benefit from it, and it's more code. Likewise I've removed the exists flag: returning as soon as you know the answer makes the code simpler.

Note that in your original code I think you had a bug. Having found that the customer at index i had the right ID, you then returned the customer at index id - I doubt that this is really what you intended.

Secondly, if you're going to do a lot of lookups by ID, have you considered putting your customers into a Map<Integer, Customer>?

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

Example:

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

Here is the documentation of <select>. You are using 2 attributes:

multiple
This Boolean attribute indicates that multiple options can be selected in the list. If it is not specified, then only one option can be selected at a time. When multiple is specified, most browsers will show a scrolling list box instead of a single line dropdown.

size
If the control is presented as a scrolling list box (e.g. when multiple is specified), this attribute represents the number of rows in the list that should be visible at one time. Browsers are not required to present a select element as a scrolled list box. The default value is 0.

As described in the docs. <select size="1" multiple> will render a List box only 1 line visible and a scrollbar. So you are loosing the dropdown/arrow with the multiple attribute.

I am doing something like below:

    StringBuilder stringBuilder = new StringBuilder();
    for (int i = 0; i < value.length; i++) {
        stringBuilder.append(values[i]);
        if (value.length-1) {
            stringBuilder.append(", ");
        }
    }

With windows7, python2.7, opencv 3.0, the following works for me:

frameslist    =   os.listdir('.\\frames')
howmanyframes =   len(frameslist)
print('Frames count: '+str(howmanyframes)) #just for debugging

for i in range(0,howmanyframes):
    print(i)
    theframe = cv2.imread('.\\frames\\'+frameslist[i])
    vvw.write(theframe)

If you can use the WebClient class, using basic authentication becomes simple:

The file msrdo20.dll is missing from the installation.

According to the Support Statement for Visual Basic 6.0 on Windows Vista, Windows Server 2008 and Windows 7 this file should be distributed with the application.

I'm not sure why it isn't, but my solution is to place the file somewhere on the machine, and register it using regsvr32 in the command line, eg:

regsvr32 c:\windows\system32\msrdo20.dll

In an ideal world you would package this up with the redistributable.

What does this thread join code mean?

To quote from the Thread.join() method javadocs:

join() Waits for this thread to die.

There is a thread that is running your example code which is probably the main thread.

1. The main thread creates and starts the t1 and t2 threads. The two threads start running in parallel.
2. The main thread calls t1.join() to wait for the t1 thread to finish.
3. The t1 thread completes and the t1.join() method returns in the main thread. Note that t1 could already have finished before the join() call is made in which case the join() call will return immediately.
4. The main thread calls t2.join() to wait for the t2 thread to finish.
5. The t2 thread completes (or it might have completed before the t1 thread did) and the t2.join() method returns in the main thread.

It is important to understand that the t1 and t2 threads have been running in parallel but the main thread that started them needs to wait for them to finish before it can continue. That's a common pattern. Also, t1 and/or t2 could have finished before the main thread calls join() on them. If so then join() will not wait but will return immediately.

t1.join() means cause t2 to stop until t1 terminates?

No. The main thread that is calling t1.join() will stop running and wait for the t1 thread to finish. The t2 thread is running in parallel and is not affected by t1 or the t1.join() call at all.

In terms of the try/catch, the join() throws InterruptedException meaning that the main thread that is calling join() may itself be interrupted by another thread.

while (true) {

Having the joins in a while loop is a strange pattern. Typically you would do the first join and then the second join handling the InterruptedException appropriately in each case. No need to put them in a loop.

So after reading a bit on how git sets up the repo. I realized that I ran the command

git push origin master

but instead for the first time I should have ran

git push -u origin master

which sets up the upstream initially. Way to go!

No need for so long Mysql code. In PHP, query should look something like this:

$updateQuery = mysql_query("UPDATE table_name SET row='value' WHERE id='$id'") or die ('Error');
$lastUpdatedId = mysql_insert_id();

Check that the server name you're logging into with SQL Management Studio matches your connection string.

I was getting this error today. It turned out that I hadn't realised the machine with SQL Server installed had multiples servers running. I had in fact put my database in a totally different server to the one I thought I was using. (So my connection string was pointing to a server with no database)

Hence, When .net tried to access the database it couldn't find anything and gave only a misleading error message about pipes.

I opened the correct server in SQL Management Studio, added my database to and then all worked fine. (If the correct server isn't available in the dropdown, try browsing for it.)

This problem is due to the https protocol, which is why the other solution works (by switching to the non-secure protocol).

For me, the best solution was to compile the latest version of node, which includes npm

apt-get purge nodejs npm
git clone https://github.com/nodejs/node ~/local/node
cd ~/local/node
./configure
make
make install

Console.Read() reads only the next character from standard input, and Console.ReadLine() reads the next line of characters from the standard input stream.

Standard input in case of Console Application is input from the user typed words in console UI of your application. Try to create it by Visual studio, and see by yourself.

import shutil
import os

files = os.listdir("./pics/") 

for key in range(0, len(files)):
   print files[key]
   shutil.move("./pics/" + files[key],"./pics/img" + str(key) + ".jpeg")

This should do it. python 3+

Here's a simple extension on UIBarButtonItem:

extension UIBarButtonItem {
    class func itemWith(colorfulImage: UIImage?, target: AnyObject, action: Selector) -> UIBarButtonItem {
        let button = UIButton(type: .custom)
        button.setImage(colorfulImage, for: .normal)
        button.frame = CGRect(x: 0.0, y: 0.0, width: 44.0, height: 44.0)
        button.addTarget(target, action: action, for: .touchUpInside)

        let barButtonItem = UIBarButtonItem(customView: button)
        return barButtonItem
    }
}

Use memory.limit(). You can increase the default using this command, memory.limit(size=2500), where the size is in MB. You need to be using 64-bit in order to take real advantage of this.

One other suggestion is to use memory efficient objects wherever possible: for instance, use a matrix instead of a data.frame.

Just found this thread and posted an alternative answer (copied below) here: https://stackoverflow.com/a/37853766/1948625

Specifically on this question, if the dot "." used in the -S value of the command line means the same as 127.0.0.1, then it could be the same issue as the connection string of the other question. Use the hostname instead, or check your hosts file.

Old question, and my symptoms are slightly different, but same error. My connection string was correct (Integrated security, and I don't provide user and pwd) with data source set to 127.0.0.1. It worked fine for years.

But recently I added a line in the static host file for testing purposes (C:\Windows\System32\drivers\etc\hosts)

127.0.0.1           www.blablatestsite.com

Removing this line and the error is gone.

I got a clue from this article (https://support.microsoft.com/en-gb/kb/896861) which talks about hostnames and loopback.

Other possible fix (if you need to keep that line in the hosts file) is to use the hostname (like MYSERVER01) instead of 127.0.0.1 in the data source of the connection string.

I made some changes to dina's answer to avoid attempting to download/combine 1200 parts if there aren't that many.

I also found it helpful to sort by waterfall in the network tab of chrome. This will sort by the time the files are downloaded, so when you are streaming a video the most recently downloaded parts will be at the top, making it easy to find the .ts links.

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

I think one can end up in this position with older versions of mysql already installed. I had the same problem and none of the above solutions worked for me. I fixed it thus:

Used brew's remove & cleanup commands, unloaded the launchctl script, then deleted the mysql directory in /usr/local/var, deleted my existing /etc/my.cnf (leave that one up to you, should it apply) and launchctl plist

Updated the string for the plist. Note also your alternate security script directory will be based on which version of MySQL you are installing.

Step-by-step:

brew remove mysql

brew cleanup

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

sudo rm -rf /usr/local/var/mysql

I then started from scratch:

1. installed mysql with brew install mysql

2. ran the commands brew suggested: (see note: below)

   unset TMPDIR
   
   mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
   

3. Start mysql with mysql.server start command, to be able to log on it

4. Used the alternate security script:

   /usr/local/Cellar/mysql/5.5.10/bin/mysql_secure_installation
   

5. Followed the launchctl section from the brew package script output such as,

   #start
   launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
   
   #stop
   launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
   

Note: the --force bit on brew cleanup will also cleanup outdated kegs, think it's a new-ish homebrew feature.

Note the second: a commenter says step 2 is not required. I don't want to test it, so YMMV!

Bash 4+ examples. Note: not using quotes will cause issues when words contain spaces, etc. Always quote in Bash, IMO.

Here are some examples in Bash 4+:

Example 1, check for 'yes' in string (case insensitive):

    if [[ "${str,,}" == *"yes"* ]] ;then

Example 2, check for 'yes' in string (case insensitive):

    if [[ "$(echo "$str" | tr '[:upper:]' '[:lower:]')" == *"yes"* ]] ;then

Example 3, check for 'yes' in string (case sensitive):

     if [[ "${str}" == *"yes"* ]] ;then

Example 4, check for 'yes' in string (case sensitive):

     if [[ "${str}" =~ "yes" ]] ;then

Example 5, exact match (case sensitive):

     if [[ "${str}" == "yes" ]] ;then

Example 6, exact match (case insensitive):

     if [[ "${str,,}" == "yes" ]] ;then

Example 7, exact match:

     if [ "$a" = "$b" ] ;then

Enjoy.

If you use phpMyAdmin, click on Home, then Variables on the top menu. Look for the port setting on the page. The value it is set to is the port your MySQL server is running on.

$instance->find() returns a reference to a variable.

You get the report when you are trying to use this reference as an argument to a function, without storing it in a variable first.

This helps preventing memory leaks and will probably become an error in the next PHP versions.

Your second code block would throw an error if it wrote like (note the & in the function signature):

function &get_arr(){
    return array(1, 2);
}
$el = array_shift(get_arr());

So a quick (and not so nice) fix would be:

$el = array_shift($tmp = $instance->find(..));

Basically, you do an assignment to a temporary variable first and send the variable as an argument.

One option is to use lapply and class. For example:

> foo <- data.frame(c("a", "b"), c(1, 2))
> names(foo) <- c("SomeFactor", "SomeNumeric")
> lapply(foo, class)
$SomeFactor
[1] "factor"

$SomeNumeric
[1] "numeric"

Another option is str:

> str(foo)
'data.frame':   2 obs. of  2 variables:
 $ SomeFactor : Factor w/ 2 levels "a","b": 1 2
 $ SomeNumeric: num  1 2

I took the best of the above and added the ability to work with any input, outside of forms, etc. Also it properly loops back to start now if you reach the last input. And in the event of only one input it blurs then refocuses the single input to trigger any external blur/focus handlers.

$('input,select').keydown( function(e) {
  var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
  if(key == 13) {
    e.preventDefault();
    var inputs = $('#content').find(':input:visible');
    var nextinput = 0;
    if (inputs.index(this) < (inputs.length-1)) {
      nextinput = inputs.index(this)+1;
    }
    if (inputs.length==1) {
      $(this).blur().focus();
    } else {
      inputs.eq(nextinput).focus();
    }
  }
});

Check out google webfonts helper

It lets you download every web font of Google and suggests css code for the implementation. This tool also allows you to simply download all formats at once without the hassle.

Ever wanted to know where Google hosts their webfonts? This service might be handy if you want to download all .eot, .woff, .woff2, .svg, .ttf files of a font variant directly from google (normally your User-Agent would determine the best format).

Also take a look at their Github page.

To resume the working solutions in VisualStudio 2013 and 2015 too:

Add an include-path to the current project only

In Solution Explorer (a palette-window of the VisualStudio-mainwindow), open the shortcut menu for the project and choose Properties, and then in the left pane of the Property Pages dialog box, expand Configuration Properties and select VC++ Directories. Additional include- or lib-paths are specifyable there.

Its the what Stackunderflow and user1741137 say in the answers above. Its the what Microsoft explains in MSDN too.

Add an include-path to every new project automatically

Its the question, what Jay Elston is asking in a comment above and what is a very obvious and burning question in my eyes, what seems to be nonanswered here yet.

There exist regular ways to do it in VisualStudio (see CurlyBrace.com), what in my experience are not working properly. In the sense, that it works only once, and thereafter, it is no more expandable and nomore removable. The approach of Steve Wilkinson in another close related thread of StackOverflow, editing the Microsoft-Factory-XML-file in the ‘program files’ - directory is probably a risky hack, as it isnt expected by Microsoft to meet there something foreign. The effect is potentally unpredictable. Well, I like rather to judge it risky not much, but anyway the best way to make VisualStudio work incomprehensible at least for someone else.

The what is working fine compared to, is the editing the corresponding User-XML-file:

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props

or/and

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user.props

For example:

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ImportGroup Label="PropertySheets">
  </ImportGroup>
  <PropertyGroup Label="UserMacros" />
  <PropertyGroup>
    <IncludePath>C:\any-name\include;$(IncludePath)</IncludePath>
    <LibraryPath>C:\any-name\lib;$(LibraryPath)</LibraryPath>
  </PropertyGroup>
  <ItemDefinitionGroup />
  <ItemGroup />
</Project>

Where the directory ‘C:\any-name\include’ will get prepended to the present include-path and the directory ‘C:\any-name\lib’ to the library-path. Here, we can edit it ago in an extending and removing sense and remove it all, removing thewhole content of the tag .

Its the what makes VisualStudio itself, doing it in the regular way what CurlyBrace describes. As said, it isnt editable in the CurlyBrace-way thereafter nomore, but in the XML-editing-way it is.

For more insight, see Brian Tyler@MSDN-Blog 2009, what is admittedly not very fresh, but always the what Microsoft is linking to.

write a button tag and on click function

var x = document.getElementById('codeRefer').innerHTML;
  document.getElementById('codeRefer').innerHTML = x;

write this all in onclick function

bottomline: if you are working offline with selects on large chunks of data, MyISAM will probably give you better (much better) speeds.

there are some situations when MyISAM is infinitely more efficient than InnoDB: when manipulating large data dumps offline (because of table lock).

example: I was converting a csv file (15M records) from NOAA which uses VARCHAR fields as keys. InnoDB was taking forever, even with large chunks of memory available.

this an example of the csv (first and third fields are keys).

USC00178998,20130101,TMAX,-22,,,7,0700
USC00178998,20130101,TMIN,-117,,,7,0700
USC00178998,20130101,TOBS,-28,,,7,0700
USC00178998,20130101,PRCP,0,T,,7,0700
USC00178998,20130101,SNOW,0,T,,7,

since what i need to do is run a batch offline update of observed weather phenomena, i use MyISAM table for receiving data and run JOINS on the keys so that i can clean the incoming file and replace VARCHAR fields with INT keys (which are related to external tables where the original VARCHAR values are stored).

Just / refers to the root of your website from the public html folder. DOCUMENT_ROOT refers to the local path to the folder on the server that contains your website.

For example, I have EasyPHP setup on a machine...

$_SERVER["DOCUMENT_ROOT"] gives me file:///C:/Program%20Files%20(x86)/EasyPHP-5.3.9/www but any file I link to with just / will be relative to my www folder.

If you want to give the absolute path to a file on your server (from the server's root) you can use DOCUMENT_ROOT. if you want to give the absolute path to a file from your website's root, use just /.

In Typescript 1.5 and later, you can use for..of as opposed to for..in

var numbers = [1, 2, 3];

for (var number of numbers) {
    console.log(number);
}

Yes, I found MySQL also cannot edit result tables. Usually results tables joining other tables don't have primary keys. I heard other suggested put the result table in another table, but the better solution is to use Dbeaver which can edit result tables.

Just a note, since I just spent some time trouble-shooting a botched upgrade on a server. Turned out, that (years ago) I had implemented a test to see if dynamically added interfaces (e.g. eth0:1) were present, and if so, I would bind certain proggis to the 'main' IP on eth0. Basically it was a variation on the 'ifconfig|grep...|sed... ' solution (plus checking for 'eth0:' presence).
The upgrade brought new net-tools, and with it the output has changed slightly:

old ifconfig:

eth0      Link encap:Ethernet  HWaddr 42:01:0A:F0:B0:1D
          inet addr:10.240.176.29  Bcast:10.240.176.29  Mask:255.255.255.255
          UP BROADCAST RUNNING MULTICAST  MTU:1460  Metric:1
          ...<SNIP>

whereas the new version will display this:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1460
      inet 10.240.212.165  netmask 255.255.255.255  broadcast 10.240.212.165
      ...<SNIP>

rendering the hunt for 'eth0:' as well as 'inet addr:' search busted (never mind interfaces called 'em0','br0' or 'wlan0'...). Sure you could check for 'inet ' (or 'inet6'), and make the addr: part optional, but looking closer, you'll see that more or less everything has changed, 'Mask' is now 'netmask',...

The 'ip route ...' suggestion's pretty nifty - so maybe:

_MyIP="$( ip route get 8.8.8.8 | awk 'NR==1 {print $NF}' )"
if [ "A$_MyIP" == "A" ]
then
    _MyIPs="$( hostname -I )"
    for _MyIP in "$_MyIPs"
    do
        echo "Found IP: \"$_MyIP\""
    done
else
    echo "Found IP: $_MyIP"
fi

Well, something of that sort anyway. Since all proposed solutions seem to have circumstances where they fail, check for possible edge cases - no eth, multiple eth's & lo's, when would 'hostname -i' fail,... and then decide on best solution, check it worked, otherwise 2nd best.

Cheers 'n' beers!

If you lost a keystore file, don't create/update the new one with another set of value. First do the thorough search. Because it will overwrite the old one, so it will not match to your previous apk.

If you use eclipse most probably it will store in default path. For MAC (eclipse) it will be in your elispse installation path something like:

/Applications/eclipse/Eclipse.app/Contents/MacOS/

then your keystore file without any extension. You need root privilege to access this path (file).

Every time I go from heavy C++ coding to Java, it takes me a little while to adapt to the lack of const-correctness in Java. This usage of const in C++ is much different than just declaring constant variables, if you didn't know. Essentially, it ensures that an object is immutable when accessed through a special kind of pointer called a const-pointer When in Java, in places where I'd normally want to return a const-pointer, I instead return a reference with an interface type containing only methods that shouldn't have side effects. Unfortunately, this isn't enforced by the langauge.

Wikipedia offers the following information on the subject:

Interestingly, the Java language specification regards const as a reserved keyword — i.e., one that cannot be used as variable identifier — but assigns no semantics to it. It is thought that the reservation of the keyword occurred to allow for an extension of the Java language to include C++-style const methods and pointer to const type. The enhancement request ticket in the Java Community Process for implementing const correctness in Java was closed in 2005, implying that const correctness will probably never find its way into the official Java specification.

split() method in JavaScript is used to convert a string to an array. It takes one optional argument, as a character, on which to split. In your case (~).

If splitOn is skipped, it will simply put string as it is on 0th position of an array.

If splitOn is just a “”, then it will convert array of single characters.

So in your case:

var arr = input.split('~');

will get the name at arr[0] and the street at arr[1].

You can read for a more detailed explanation at Split on in JavaScript

This simple example for multidimensional array with function pointers":

void one( int a, int b){    printf(" \n[ ONE ]  a =  %d   b = %d",a,b);}
void two( int a, int b){    printf(" \n[ TWO ]  a =  %d   b = %d",a,b);}
void three( int a, int b){    printf("\n [ THREE ]  a =  %d   b = %d",a,b);}
void four( int a, int b){    printf(" \n[ FOUR ]  a =  %d   b = %d",a,b);}
void five( int a, int b){    printf(" \n [ FIVE ]  a =  %d   b = %d",a,b);}
void(*p[2][2])(int,int)   ;
int main()
{
    int i,j;
    printf("multidimensional array with function pointers\n");

    p[0][0] = one;    p[0][1] = two;    p[1][0] = three;    p[1][1] = four;
    for (  i  = 1 ; i >=0; i--)
        for (  j  = 0 ; j <2; j++)
            (*p[i][j])( (i, i*j);
    return 0;
}

It means that the value type in question is a nullable type

Nullable types are instances of the System.Nullable struct. A nullable type can represent the correct range of values for its underlying value type, plus an additional null value. For example, a Nullable<Int32>, pronounced "Nullable of Int32," can be assigned any value from -2147483648 to 2147483647, or it can be assigned the null value. A Nullable<bool> can be assigned the values true, false, or null. The ability to assign null to numeric and Boolean types is especially useful when you are dealing with databases and other data types that contain elements that may not be assigned a value. For example, a Boolean field in a database can store the values true or false, or it may be undefined.

class NullableExample
{
  static void Main()
  {
      int? num = null;

      // Is the HasValue property true?
      if (num.HasValue)
      {
          System.Console.WriteLine("num = " + num.Value);
      }
      else
      {
          System.Console.WriteLine("num = Null");
      }

      // y is set to zero
      int y = num.GetValueOrDefault();

      // num.Value throws an InvalidOperationException if num.HasValue is false
      try
      {
          y = num.Value;
      }
      catch (System.InvalidOperationException e)
      {
          System.Console.WriteLine(e.Message);
      }
  }
}

Or something like:

df.loc[df['a'].isnull(),'a']=0
df.loc[df['b'].isnull(),'b']=0

and if there is more:

for i in your_list:
    df.loc[df[i].isnull(),i]=0

You can use File.Exists to check if the file exists and create it using File.Create if required. Make sure you check if you have access to create files at that location.

Once you are certain that the file exists, you can write to it safely. Though as a precaution, you should put your code into a try...catch block and catch for the exceptions that function is likely to raise if things don't go exactly as planned.

Additional information for basic file I/O concepts.

I found this useful and easy to use, plus it looks pretty: http://maxailloud.github.io/confirm-bootstrap/.

To use it, include the .js file in your page then run:

$('your-link-selector').confirmModal();

There are various options you can apply to it, to make it look better when doing it to confirm a delete, I use:

$('your-link-selector').confirmModal({
    confirmTitle: 'Please confirm',
    confirmMessage: 'Are you sure you want to delete this?',
    confirmStyle: 'danger',
    confirmOk: '<i class="icon-trash icon-white"></i> Delete',
    confirmCallback: function (target) {
         //perform the deletion here, or leave this option
         //out to just follow link..
    }
});

if you have scenario in which you have to remove more then one values from the foreach array in this case you have to pass value by reference in for each: I try to explain this scenario:

foreach ($manSkuQty as $man_sku => &$man_qty) {

               foreach ($manufacturerSkus as $key1 => $val1) {

  // some processing here and unset first loops entries                     
 //  here dont include again for next iterations
                           if(some condition)
                            unset($manSkuQty[$key1]);

                        }
               }
}

in second loop you want to unset first loops entries dont come again in the iteration for performance purpose or else then unset from memory as well because in memory they present and will come in iterations.

document.forms[ 'forms1' ].onsubmit = function() {
    return [].some.call( this.elements, function( el ) {
        return el.type === 'radio' ? el.checked : false
    } )
}

Just something out of my head. Not sure the code is working.

A simplified way to compare 2 directories using the DIFF command

diff filename.1 filename.2 > filename.dat >>Enter

open filename.dat after the run is complete

and you will see: Only in filename.1: filename.2 Only in: directory_name: name_of_file1 Only in: directory_Name: name_of_file2

Although this question is old, it is still relevant for my more or less up-to-date system. After enabling debug mode of sudo (Debug sudo /var/log/sudo_debug all@info in /etc/sudo.conf) I was pointed to /dev: "/dev is world writable". So you might need to check the tty file permissions, especially those of the directory where the tty/pts node resides in.

Download the file and from the same directory run docker build -t nodebb .

This will give you an image on your local machine that's named nodebb that you can launch an container from with docker run -d nodebb (you can change nodebb to your own name).

Add this inside your pages head tag (targeting the IE version you want):

<meta http-equiv="X-UA-Compatible" content="IE=8" />  

Note, this will NOT change the fact that the browser says its in compatibility mode (called the browser mode), but the page will render in IE8 standards mode. If its STILL not rendering how you wish, its probably because you have javascript that is erroneously checking the I.E. version. See the following blog post to determine which property you should be keying off of because even if you set the meta X-UA-Compatible tag, the user agent string will still say MSIE 7.0.

In my case, for the fix I had to add a check for IE7 Compatibility mode. I did so using a simple javascript code:

                //IE8 and later will have the word 'trident' in its user agent string.
                if (navigator.userAgent.indexOf("Trident")>-1) { //do something }

If you are interessted in a more far-reaching solution to get all meta tags you could use this piece of code

function getAllMetas() {
    var metas = document.getElementsByTagName('meta');
    var summary = [];
    Array.from(metas)
        .forEach((meta) => {
            var tempsum = {};
            var attributes = meta.getAttributeNames();
            attributes.forEach(function(attribute) {
                tempsum[attribute] = meta.getAttribute(attribute);
            });
            summary.push(tempsum);
        });
    return summary;
}

// usage
console.log(getAllMetas());

Just spent 4 hours with this problem. Finally realized that you must not use zero as view id. You would think that it is allowed as NO_ID == -1, but things tend to go haywire if you give it to your view...

Search for EnableOptimizations keyword in your project

So if you find

BundleTable.EnableOptimizations = true;

turn it false.

This does disable minification, And it also disables bundling entirely

I think it's more convenient and easy to use.

   List<Whatever> _lobj= new List<Whatever>(); 
    var json = JsonConvert.SerializeObject(_lobj);
                DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

AffineTransform instances can be concatenated (added together). Therefore you can have a transform that combines 'shift to origin', 'rotate' and 'shift back to desired position'.

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

The few lines you posted from your script look okay to me. It's probably something a bit deeper.

You need to find which line is giving you this error. Add set -xv to the top of your script. This will print out the line number and the command that's being executed to STDERR. This will help you identify where in your script you're getting this particular error.

BTW, do you have a shebang at the top of your script? When I see something like this, I normally expect its an issue with the Shebang. For example, if you had #! /bin/bash on top, but your bash interpreter is located in /usr/bin/bash, you'll see this error.

EDIT

New question: How can I save the file correctly in the first place, to avoid having to perform this fix every time I resend the file?

Two ways:

1. Select the Edit->EOL Conversion->Unix Format menu item when you edit a file. Once it has the correct line endings, Notepad++ will keep them.
2. To make sure all new files have the correct line endings, go to the Settings->Preferences menu item, and pull up the Preferences dialog box. Select the New Document/Default Directory tab. Under New Document and Format, select the Unix radio button. Click the Close button.

To just get a date you can cast it

cast(user.registration as date)

and to get a specific format use date_format

date_format(registration, '%Y-%m-%d')

I'm a bit surprised nobody suggested creating a pipe, which is in my opinion the far simplest way to pass a string to stdin of a subprocess:

read, write = os.pipe()
os.write(write, "stdin input here")
os.close(write)

subprocess.check_call(['your-command'], stdin=read)

I realize this is a little old, but, yes it can be done. Some javascript to get you started:

viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');

Just change the parts you need and Mobile Safari will respect the new settings.

Update:

If you don't already have the meta viewport tag in the source, you can append it directly with something like this:

var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);

Or if you're using jQuery:

$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');

I recently used py2exe to create an executable for post-review for sending reviews to ReviewBoard.

This was the setup.py I used

from distutils.core import setup
import py2exe

setup(console=['post-review'])

It created a directory containing the exe file and the libraries needed. I don't think it is possible to use py2exe to get just a single .exe file. If you need that you will need to first use py2exe and then use some form of installer to make the final executable.

One thing to take care of is that any egg files you use in your application need to be unzipped, otherwise py2exe can't include them. This is covered in the py2exe docs.

You can try xml2js. It's a simple XML to JavaScript object converter. It gets your XML converted to a JS object so that you can access its content with ease.

Here are some other options:

1. libxmljs
2. xml-stream
3. xmldoc
4. cheerio – implements a subset of core jQuery for XML (and HTML)

I have used xml2js and it has worked fine for me. The rest you might have to try out for yourself.

Select the body tab and select application/json in the Content-Type drop-down and add a body like this:

{
  "Username":"ABC",
  "Password":"ABC"
}

If you need use it in the code.

Your syntax is pretty screwy.

Change this:

input:not(disabled)not:[type="submit"]:focus{

to:

input:not(:disabled):not([type="submit"]):focus{

Seems that many people don't realize :enabled and :disabled are valid CSS selectors...

This problem occurs when you already had MySQL installed on your machine or in case you have changed the post number of the MySql service which is 3306(Default). In order to solve this, you have to tell the phpMyAdmin to look for another port instead of 3306. To do so go to C:\xampp\phpMyAdmin(default location) and open Config.inc and add this line $cfg['Servers'][$i]['port'] = '3307'; after $cfg['Servers'][$i]['AllowNoPassword'] = true; Restart the services and now it should work.

I just want to add with @Noby Fujioka's response, Edge will not support following

window.open("data:application/pdf," + encodeURI(pdfString));

For Edge we need to convert it to blob and this is something like following

//If Browser is Edge
            if (window.navigator && window.navigator.msSaveOrOpenBlob) {
                var byteCharacters = atob(<Your_base64_Report Data>);
                var byteNumbers = new Array(byteCharacters.length);
                for (var i = 0; i < byteCharacters.length; i++) {
                    byteNumbers[i] = byteCharacters.charCodeAt(i);
                }
                var byteArray = new Uint8Array(byteNumbers);
                var blob = new Blob([byteArray], {
                    type: 'application/pdf'
                });
                window.navigator.msSaveOrOpenBlob(blob, "myreport.pdf");
            } else {
                var pdfWindow = window.open("", '_blank');
                pdfWindow.document.write("<iframe width='100%' style='margin: -8px;border: none;' height='100%' src='data:application/pdf;base64, " + encodeURI(<Your_base64_Report Data>) + "'></iframe>");
            }

You can't cast an object to a Double if the object is not a Double.

Check out the API.

particularly note

valueOf(double d);

and

valueOf(String s);

Those methods give you a way of getting a Double instance from a String or double primitive. (Also not the constructors; read the documentation to see how they work) The object you are trying to convert naturally has to give you something that can be transformed into a double.

Finally, keep in mind that Double instances are immutable -- once created you can't change them.

After wrestling with this problem today my opinion is this: BEGIN...END brackets code just like {....} does in C languages, e.g. code blocks for if...else and loops

GO is (must be) used when succeeding statements rely on an object defined by a previous statement. USE database is a good example above, but the following will also bite you:

alter table foo add bar varchar(8);
-- if you don't put GO here then the following line will error as it doesn't know what bar is.
update foo set bar = 'bacon';
-- need a GO here to tell the interpreter to execute this statement, otherwise the Parser will lump it together with all successive statements.

It seems to me the problem is this: the SQL Server SQL Parser, unlike the Oracle one, is unable to realise that you're defining a new symbol on the first line and that it's ok to reference in the following lines. It doesn't "see" the symbol until it encounters a GO token which tells it to execute the preceding SQL since the last GO, at which point the symbol is applied to the database and becomes visible to the parser.

Why it doesn't just treat the semi-colon as a semantic break and apply statements individually I don't know and wish it would. Only bonus I can see is that you can put a print() statement just before the GO and if any of the statements fail the print won't execute. Lot of trouble for a minor gain though.

Is there a way ( I mean how do I ) set a system property in a maven project? I want to access a property from my test [...]

You can set system properties in the Maven Surefire Plugin configuration (this makes sense since tests are forked by default). From Using System Properties:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.5</version>
        <configuration>
          <systemPropertyVariables>
            <propertyName>propertyValue</propertyName>
            <buildDirectory>${project.build.directory}</buildDirectory>
            [...]
          </systemPropertyVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

and my webapp ( running locally )

Not sure what you mean here but I'll assume the webapp container is started by Maven. You can pass system properties on the command line using:

mvn -DargLine="-DpropertyName=propertyValue"

Update: Ok, got it now. For Jetty, you should also be able to set system properties in the Maven Jetty Plugin configuration. From Setting System Properties:

<project>
  ...
  <plugins>
    ...
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <configuration>
         ...
         <systemProperties>
            <systemProperty>
              <name>propertyName</name>
              <value>propertyValue</value>
            </systemProperty>
            ...
         </systemProperties>
        </configuration>
      </plugin>
  </plugins>
</project>

Same problem here, solved with this: In Eclipse (with .js file open and on focus), go to, "File", "Properties", "Resource", "Text file encoding" choose "Other:" UTF-8, put correct characters code inside the code save your file and you are done!

Remove servlet.jar from source web-inf/lib folder as it is available in tomcat lib folder then it works fine

I encountered the same issue (dialog would only open once, after closing, it wouldn't open again), and tried the solutions above which did not fix my problem. I went back to the docs and realized I had a fundamental misunderstanding of how the dialog works.

The $('#myDiv').dialog() command creates/instantiates the dialog, but is not necessarily the proper way to open it. The proper way to open it is to instantiate the dialog with dialog(), then use dialog('open') to display it, and dialog('close') to close/hide it. This means you'll probably want to set the autoOpen option to false.

So the process is: instantiate the dialog on document ready, then listen for the click or whatever action you want to show the dialog. Then it will work, time after time!

<script type="text/javascript"> 
        jQuery(document).ready( function(){       
            jQuery("#myButton").click( showDialog );

            //variable to reference window
            $myWindow = jQuery('#myDiv');

            //instantiate the dialog
            $myWindow.dialog({ height: 350,
                width: 400,
                modal: true,
                position: 'center',
                autoOpen:false,
                title:'Hello World',
                overlay: { opacity: 0.5, background: 'black'}
                });
            }

        );
    //function to show dialog   
    var showDialog = function() {
        //if the contents have been hidden with css, you need this
        $myWindow.show(); 
        //open the dialog
        $myWindow.dialog("open");
        }

    //function to close dialog, probably called by a button in the dialog
    var closeDialog = function() {
        $myWindow.dialog("close");
    }


</script>
</head>

<body>

<input id="myButton" name="myButton" value="Click Me" type="button" />
<div id="myDiv" style="display:none">
    <p>I am a modal dialog</p>
</div>

Many ways to do this. You could use wildcards in double brackets:

str="/some/directory/file"
if [[ $str == /* ]]; then echo 1; else echo 0; fi

You can use substring expansion:

if [[ ${str:0:1} == "/" ]] ; then echo 1; else echo 0; fi

Or a regex:

if [[ $str =~ ^/ ]]; then echo 1; else echo 0; fi

The answer is simple. Just divide string by 1. Examples:

"2" > "10"   - true

but

"2"/1 > "10"/1 - false

Also you can check if string value really is number:

!isNaN("1"/1) - true (number)
!isNaN("1a"/1) - false (string)
!isNaN("01"/1) - true (number)
!isNaN(" 1"/1) - true (number)
!isNaN(" 1abc"/1) - false (string)

But

!isNaN(""/1) - true (but string)

Solution

number !== "" && !isNaN(number/1)

I stumbled upon this old listing pondering this same question. My band-aid for this same question was to make my header text into a link. I then changed the color and removed text decoration with CSS. Now to make the entire header picture a link, I expanded the padding of the anchor tag until it reached close to the edge of the header image.... This worked to my satisfaction, and I figured i would share.

Install "vbox-ssl-cacertificate.crt" certificate from %userprofile%\\.virtualbox\ and then reboot. If you don't have .virtualbox folder - launch "Oracle VM VirtualBox" once and this folder will appear.

I had this issue not only on my machine but on many hosts, and this certificate fixed the issue. I figured it out by chance, because nowhere said about this certificate -_-

1. this is just simple here i'm appending html table into a div at the end
2. we can achieve this or any thing with a simple concept of calling a JavaScript function when we want (here on drop.)
3. In this example you can drag & drop any number of tables, new table will be added below the last table exists in the div other wise it will be the first table in the div.
4. here we can add text between tables or we can say the section where we drop tables is editable we can type text between tables.

While not contesting the other answers, I think the following is worthy of mentioning.

1. The “long” (http-equiv) notation and the “short” one are equal, whichever comes first wins;
2. Web server headers will override all the <meta> tags;
3. BOM (Byte order mark) will override everything, and in many cases it will affect html 4 (and probably other stuff, too);
4. If you don't declare any encoding, you will probably get your text in “fallback text encoding” that is defined your browser. Neither in Firefox nor in Chrome it's utf-8;
5. In absence of other clues the browser will attempt to read your document as if it was in ASCII to get the encoding, so you can't use any weird encodings (utf-16 with BOM should do, though);
6. While the specs say that the encoding declaration must be within the first 512 bytes of the document, most browsers will try reading more than that.

You can test by running echo 'HTTP/1.1 200 OK\r\nContent-type: text/html; charset=windows-1251\r\n\r\n\xef\xbb\xbf<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta charset="windows-1251"><title>??????</title></head><body>??????</body></html>' | nc -lp 4500 and pointing your browser at localhost:4500. (Of course you will want to change or remove parts. The BOM part is \xef\xbb\xbf. Be wary of the encoding of your shell.)

Please mind that it's very important that you explicitly declare the encoding. Letting browsers guess can lead to security issues.

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

I am using maven-assembly-plugin for my maven packaging. The usage of Apache Maven Archiver in Joachim Sauer's answer could also work:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
        <archive>
            <manifest>
                <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                <addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
            </manifest>
        </archive>
    </configuration>
    <executions>
        <execution .../>
    </executions>
</plugin>

Because archiever is one of maven shared components, it could be used by multiple maven building plugins, which could also have conflict if two or more plugins introduced, including archive configuration inside.

I had the same issue in AWS RDS. It was due to the Freeable Space (Hard Drive Storage Space) was Full. You need to increase your space, or remove some data.

You can use the following regular expression.

string.split(/ /)[0].replace(/[^\d]/g, '')

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

There should be a more succinct solution than the accepted answer. It shouldn't take three steps to run multiple tasks simultaneously and get their results.

1. Create tasks
2. await Task.WhenAll(tasks)
3. Get task results (e.g., task1.Result)

Here's a method that cuts this down to two steps:

    public async Task<Tuple<T1, T2>> WhenAllGeneric<T1, T2>(Task<T1> task1, Task<T2> task2)
    {
        await Task.WhenAll(task1, task2);
        return Tuple.Create(task1.Result, task2.Result);
    }

You can use it like this:

var taskResults = await Task.WhenAll(DoWorkAsync(), DoMoreWorkAsync());
var DoWorkResult = taskResults.Result.Item1;
var DoMoreWorkResult = taskResults.Result.Item2;

This removes the need for the temporary task variables. The problem with using this is that while it works for two tasks, you'd need to update it for three tasks, or any other number of tasks. Also it doesn't work well if one of the tasks doesn't return anything. Really, the .Net library should provide something that can do this

The return statement exits a function from anywhere within the function:

function something(x)
{
    if (x >= 10)
        // this leaves the function if x is at least 10.
        return;

    // this message displays only if x is less than 10.
    alert ("x is less than 10!");
}

Late answer, but hopefully worthwhile: The Poor Man's T-SQL Formatter is an open-source (free) T-SQL formatter with complete T-SQL batch/script support (any DDL, any DML), SSMS Plugin, command-line bulk formatter, and other options.

It's available for immediate/online use at http://poorsql.com, and just today graduated to "version 1.0" (it was in beta version for a few months), having just acquired support for MERGE statements, OUTPUT clauses, and other finicky stuff.

The SSMS Add-in allows you to set your own hotkey (default is Ctrl-K, Ctrl-F, to match Visual Studio), and formats the entire script or just the code you have selected/highlighted, if any. Output formatting is customizable.

In SSMS 2008 it combines nicely with the built-in intelli-sense, effectively providing more-or-less the same base functionality as Red Gate's SQL Prompt (SQL Prompt does, of course, have extra stuff, like snippets, quick object scripting, etc).

Feedback/feature requests are more than welcome, please give it a whirl if you get the chance!

Disclosure: This is probably obvious already but I wrote this library/tool/site, so this answer is also shameless self-promotion :)

In okhttp v4.* I got it working that way

// import the extensions!
import okhttp3.MediaType.Companion.toMediaType
import okhttp3.RequestBody.Companion.toRequestBody

val jsonBody: RequestBody = json.toRequestBody(JSON)

// go on with Request.Builder() etc

Here are two simple kotlin extension functions over view.

fun View.expand() {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, -height.toFloat(), 0f)
    animate.duration = 200
    animate.fillAfter = true
    startAnimation(animate)
}

fun View.collapse() {
    val animate = TranslateAnimation(0f, 0f, 0f, -height.toFloat() )
    animate.duration = 200
    animate.fillAfter = true
    startAnimation(animate)
}

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

Almost everywhere you look, people refer to the about:config and the security.fileuri.strict_origin_policy. Sometimes also the network.http.refere.XOriginPolicy.

For me, none of these seem to have any effect.

This comment implies there is no built-in way in Firefox to do this (as of 2/8/14).

set rowcount 1000000
Update table set int_field = -1 where int_field<>-1

see how fast that takes, adjust and repeat as necessary

import json
some_list = ['one', 'two', 'three', 'four']
print(json.dumps(some_list, indent=4))

Output:

[
    "one",
    "two",
    "three",
    "four"
]

Mark,

I believe you want to use android:scaleType="fitXY".

char s[] = "Hello world";

Here, s is an array of characters, which can be overwritten if we wish.

char *s = "hello";

A string literal is used to create these character blocks somewhere in the memory which this pointer s is pointing to. We can here reassign the object it is pointing to by changing that, but as long as it points to a string literal the block of characters to which it points can't be changed.

Here you can find info on how to upgrade to v3: http://tosbourn.com/2013/08/javascript/upgrading-from-bootstraps-typeahead-to-typeahead-js/

Here are some examples too: http://twitter.github.io/typeahead.js/examples/

OUTDATED - see this answer for a simpler approach

To obtain readable x tick labels without additional dependencies, you want to use:

  ... +
  theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5)) +
  ...

This rotates the tick labels 90° counterclockwise and aligns them vertically at their end (hjust = 1) and their centers horizontally with the corresponding tick mark (vjust = 0.5).

Full example:

library(ggplot2)
data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))
q <- qplot(cut,carat,data=diamonds,geom="boxplot")
q + theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))

Note, that vertical/horizontal justification parameters vjust/hjust of element_text are relative to the text. Therefore, vjust is responsible for the horizontal alignment.

Without vjust = 0.5 it would look like this:

q + theme(axis.text.x = element_text(angle = 90, hjust = 1))

Without hjust = 1 it would look like this:

q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5))

If for some (wired) reason you wanted to rotate the tick labels 90° clockwise (such that they can be read from the left) you would need to use: q + theme(axis.text.x = element_text(angle = -90, vjust = 0.5, hjust = -1)).

All of this has already been discussed in the comments of this answer but I come back to this question so often, that I want an answer from which I can just copy without reading the comments.

?"[" pretty much covers the various ways of accessing elements of things.

Under usage it lists these:

x[i]
x[i, j, ... , drop = TRUE]
x[[i, exact = TRUE]]
x[[i, j, ..., exact = TRUE]]
x$name
getElement(object, name)

x[i] <- value
x[i, j, ...] <- value
x[[i]] <- value
x$i <- value

The second item is sufficient for your purpose

Under Arguments it points out that with [ the arguments i and j can be numeric, character or logical

So these work:

data[1,1]
data[1,"V1"]

As does this:

data$V1[1]

and keeping in mind a data frame is a list of vectors:

data[[1]][1]
data[["V1"]][1]

will also both work.

So that's a few things to be going on with. I suggest you type in the examples at the bottom of the help page one line at a time (yes, actually type the whole thing in one line at a time and see what they all do, you'll pick up stuff very quickly and the typing rather than copypasting is an important part of helping to commit it to memory.)

Just the same way as you would do in command console. Copy exactly those commands in the batch file.

Here is an example of callbacks in C.

Let's say you want to write some code that allows registering callbacks to be called when some event occurs.

First define the type of function used for the callback:

typedef void (*event_cb_t)(const struct event *evt, void *userdata);

Now, define a function that is used to register a callback:

int event_cb_register(event_cb_t cb, void *userdata);

This is what code would look like that registers a callback:

static void my_event_cb(const struct event *evt, void *data)
{
    /* do stuff and things with the event */
}

...
   event_cb_register(my_event_cb, &my_custom_data);
...

In the internals of the event dispatcher, the callback may be stored in a struct that looks something like this:

struct event_cb {
    event_cb_t cb;
    void *data;
};

This is what the code looks like that executes a callback.

struct event_cb *callback;

...

/* Get the event_cb that you want to execute */

callback->cb(event, callback->data);

Here is your answer:

if "insert_char_or_string_here" in "insert_string_to_search_here":
    #DOSTUFF

For checking if it is false:

if not "insert_char_or_string_here" in "insert_string_to_search_here":
    #DOSTUFF

OR:

if "insert_char_or_string_here" not in "insert_string_to_search_here":
    #DOSTUFF

Does it have something to do with preventing other events on the page from firing?

Yes.

Setting async to false means that the statement you are calling has to complete before the next statement in your function can be called. If you set async: true then that statement will begin it's execution and the next statement will be called regardless of whether the async statement has completed yet.

I managed to solved this by adding FcgidBusyTimeout . Just in case if anyone have similar issue with me.

Here is my settings on my apache.conf:

<VirtualHost *:80>
.......
<IfModule mod_fcgid.c>
FcgidBusyTimeout 3600
</IfModule>
</VirtualHost>

The path with reference to root directory is called absolute. The path with reference to current directory is called relative.

You can compare two images using functions from PIL.

import Image
import ImageChops

im1 = Image.open("splash.png")
im2 = Image.open("splash2.png")

diff = ImageChops.difference(im2, im1)

The diff object is an image in which every pixel is the result of the subtraction of the color values of that pixel in the second image from the first image. Using the diff image you can do several things. The simplest one is the diff.getbbox() function. It will tell you the minimal rectangle that contains all the changes between your two images.

You can probably implement approximations of the other stuff mentioned here using functions from PIL as well.

I had the exact same error.

It was because i didn't run setup_xampp.bat

This is a better solution than going through config files and changing ports.

Read-Host is one example of a cmdlet that -Confirm does not have an effect on.-Confirm is one of PowerShell's Common Parameters specifically a Risk-Mitigation Parameter which is used when a cmdlet is about to make a change to the system that is outside of the Windows PowerShell environment. Many but not all cmdlets support the -Confirm risk mitigation parameter.

As an alternative the following would be an example of using the Read-Host cmdlet and a regular expression test to get confirmation from a user:

$reply = Read-Host -Prompt "Continue?[y/n]"
if ( $reply -match "[yY]" ) { 
    # Highway to the danger zone 
}

The Remove-Variable cmdlet is one example that illustrates the usage of the -confirm switch.

Remove-Variable 'reply' -Confirm

You need to write() the read() data into the new file:

ssize_t nrd;
int fd;
int fd1;

fd = open(aa[1], O_RDONLY);
fd1 = open(aa[2], O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
while (nrd = read(fd,buffer,50)) {
    write(fd1,buffer,nrd);
}

close(fd);
close(fd1);

Update: added the proper opens...

Btw, the O_CREAT can be OR'd (O_CREAT | O_WRONLY). You are actually opening too many file handles. Just do the open once.

You can write a very elegant solution using a functional style.

class Object
  def hashify
    Hash[instance_variables.map { |v| [v.to_s[1..-1].to_sym, instance_variable_get v] }]
  end
end

The existing answers are good and correct, however what if you need to undo the push but:

1. You want to keep the commits locally or you want to keep uncommitted changes
2. You don't know how many commits you just pushed

Use this command to revert the change to the ref:

git push -f origin refs/remotes/origin/<branch>@{1}:<branch>

Use sort -n or sort --numeric-sort.

I had to add "Current" using .NET 4.5:

HttpContext.Current.Server.ScriptTimeout = 300;

I got the error with a space in a Sheet Name:

using (var range = _excelApp.Range["Sheet Name Had Space!$A$1"].WithComCleanup())

I fixed it by putting single quotes around Sheet Names with spaces:

using (var range = _excelApp.Range["'Sheet Name Had Space'!$A$1"].WithComCleanup())

There is a specific keyword for the achieving the same.

SELECT DISTINCT( Date ) AS Date 
FROM   buy 
ORDER  BY Date DESC; 

'L' means wchar_t, which, as opposed to a normal character, requires 16-bits of storage rather than 8-bits. Here's an example:

"A"    = 41
"ABC"  = 41 42 43
L"A"   = 00 41
L"ABC" = 00 41 00 42 00 43

A wchar_t is twice big as a simple char. In daily use you don't need to use wchar_t, but if you are using windows.h you are going to need it.

I found Array.prototype.reverse unsuccessful with objects, so I made a new jQuery function to use as an alternative: jQuery.eachBack(). It iterates through as the normal jQuery.each() would, and stores each key into an array. It then reverses that array and performs the callback on the original array/object in the order of the reversed keys.

jQuery.eachBack=function (obj, callback) {
    var revKeys=[]; $.each(obj,function(rind,rval){revKeys.push(rind);}); 
    revKeys.reverse();
    $.each(revKeys,function (kind,i){
        if(callback.call(obj[i], i, obj[i]) === false) {    return false;}
    });
    return obj;
}   
jQuery.fn.eachBack=function (callback,args) {
    return jQuery.eachBack(this, callback, args);
}

ALTER TABLE TABLE_NAME MODIFY COLUMN_NAME VARCHAR(40);

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

echo You must invoke st from within branch directory
SvnUrl=`svn info | grep URL | sed 's/URL: //'`
SvnVer=`svn info | grep Revision | sed 's/Revision: //'`
svn diff -r $SvnVer --summarize $SvnUrl

You can use onLayout to get the width, height, and relative-to-parent position of a component at the earliest moment that they're available:

<View
  onLayout={event => {
    const layout = event.nativeEvent.layout;
    console.log('height:', layout.height);
    console.log('width:', layout.width);
    console.log('x:', layout.x);
    console.log('y:', layout.y);
  }}

Compared to using .measure() as shown in the accepted answer, this has the advantage that you'll never have to fiddle around deferring your .measure() calls with setTimeout to make sure that the measurements are available, but the disadvantage that it doesn't give you offsets relative to the entire page, only ones relative to the element's parent.

I, always use view extension to make view corners round, set border color and width and it has been the most convenient way for me. just copy and paste this code and controlle these properties in attribute inspector.

extension UIView {
    @IBInspectable
    var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }

When setting Environmental Variables in Windows, I have gone wrong on many, many occasions. I thought I should share a few of my past mistakes here hoping that it might help someone. (These apply to all Environmental Variables, not just when setting Python Path)

Watch out for these possible mistakes:

1. Kill and reopen your shell window: Once you make a change to the ENVIRONMENTAL Variables, you have to restart the window you are testing it on.
2. NO SPACES when setting the Variables. Make sure that you are adding the ;C:\Python27 WITHOUT any spaces. (It is common to try C:\SomeOther; C:\Python27 That space (?) after the semicolon is not okay.)
3. USE A BACKWARD SLASH when spelling out your full path. You will see forward slashes when you try echo $PATH but only backward slashes have worked for me.
4. DO NOT ADD a final backslash. Only C:\Python27 NOT C:\Python27\

Hope this helps someone.

A JMS topic is the type of destination in a 1-to-many model of distribution. The same published message is received by all consuming subscribers. You can also call this the 'broadcast' model. You can think of a topic as the equivalent of a Subject in an Observer design pattern for distributed computing. Some JMS providers efficiently choose to implement this as UDP instead of TCP. For topic's the message delivery is 'fire-and-forget' - if no one listens, the message just disappears. If that's not what you want, you can use 'durable subscriptions'.

A JMS queue is a 1-to-1 destination of messages. The message is received by only one of the consuming receivers (please note: consistently using subscribers for 'topic client's and receivers for queue client's avoids confusion). Messages sent to a queue are stored on disk or memory until someone picks it up or it expires. So queues (and durable subscriptions) need some active storage management, you need to think about slow consumers.

In most environments, I would argue, topics are the better choice because you can always add additional components without having to change the architecture. Added components could be monitoring, logging, analytics, etc. You never know at the beginning of the project what the requirements will be like in 1 year, 5 years, 10 years. Change is inevitable, embrace it :-)

import numpy as np   
>>> np.shape(a)
(2,2)

Also works if the input is not a numpy array but a list of lists

>>> a = [[1,2],[1,2]]
>>> np.shape(a)
(2,2)

Or a tuple of tuples

>>> a = ((1,2),(1,2))
>>> np.shape(a)
(2,2)

This might work for you (GNU sed):

sed ':a;$!N;1,4ba;P;$d;D' file

Here is an example:

>>> u = u'€€€'
>>> s = u.encode('utf8')
>>> s
'\xe2\x82\xac\xe2\x82\xac\xe2\x82\xac'

A variation on Jorenko's work above allows the elevated process to use the same console (but see my comment below):

def spawn_as_administrator():
    """ Spawn ourself with administrator rights and wait for new process to exit
        Make the new process use the same console as the old one.
          Raise Exception() if we could not get a handle for the new re-run the process
          Raise pywintypes.error() if we could not re-spawn
        Return the exit code of the new process,
          or return None if already running the second admin process. """

If you want to open a page or window with sending data POST or GET method you can use a code like this:

$.ajax({
    type: "get",  // or post method, your choice
    url: yourFileForInclude.php, // any url in same origin
    data: data,  // data if you need send some data to page
    success: function(msg){
                console.log(msg); // for checking
                window.open('about:blank').document.body.innerHTML = msg;  
               }
}); 

import java.net.DatagramSocket;
import java.net.InetAddress;

try(final DatagramSocket socket = new DatagramSocket()){
  socket.connect(InetAddress.getByName("8.8.8.8"), 10002);
  ip = socket.getLocalAddress().getHostAddress();
}

This way works well when there are multiple network interfaces. It always returns the preferred outbound IP. The destination 8.8.8.8 is not needed to be reachable.

Connect on a UDP socket has the following effect: it sets the destination for Send/Recv, discards all packets from other addresses, and - which is what we use - transfers the socket into "connected" state, settings its appropriate fields. This includes checking the existence of the route to the destination according to the system's routing table and setting the local endpoint accordingly. The last part seems to be undocumented officially but it looks like an integral trait of Berkeley sockets API (a side effect of UDP "connected" state) that works reliably in both Windows and Linux across versions and distributions.

So, this method will give the local address that would be used to connect to the specified remote host. There is no real connection established, hence the specified remote ip can be unreachable.

Edit:

As @macomgil says, for MacOS you can do this:

Socket socket = new Socket();
socket.connect(new InetSocketAddress("google.com", 80));
System.out.println(socket.getLocalAddress());

You can also fetch data with hooks in your function components

full example with api call: https://codesandbox.io/s/jvvkoo8pq3

second example: https://jsfiddle.net/bradcypert/jhrt40yv/6/

const Repos = ({user}) => {
  const [repos, setRepos] = React.useState([]);

  React.useEffect(() => {
    const fetchData = async () => {
        const response = await axios.get(`https://api.github.com/users/${user}/repos`);
        setRepos(response.data);
    }

    fetchData();
  }, []);

  return (
  <div>
    {repos.map(repo =>
      <div key={repo.id}>{repo.name}</div>
    )}
  </div>
  );
}

ReactDOM.render(<Repos user="bradcypert" />, document.querySelector("#app"))

read = com.ExecuteReader()

SqlDataReader has a function Read() that reads the next row from your query's results and returns a bool whether it found a next row to read or not. So you need to check that before you actually get the columns from your reader (which always just gets the current row that Read() got). Or preferably make a loop while(read.Read()) if your query returns multiple rows.

I agree with Chris, checking the extension is not validation of the type of file any way you look at it. Telerik's radUpload is probably your best option, it provides a ContentType property of the file being uploaded, which you can compare to known mime types. You should check for:

application/vnd.ms-excel,

application/excel,

application/x-msexcel

and for the new 2k7 format:

application/vnd.openxmlformatsofficedocument.spreadsheetml.sheet

Telerik used to sell radUpload as an individual component, but now its wrapped into the controls suite, which makes it a little more expensive, but by far its the easiest way to check for the true type

public static class DateTimeExtensions
{
    public static DateTime LastDayOfMonth(this DateTime date)
    {
        return date.AddDays(1-(date.Day)).AddMonths(1).AddDays(-1);
    }
}

If you:

 git push origin master

it will push to the bare repo.

It sounds like your alice repo isn't tracking correctly.

cat .git/config

This will show the default remote and branch.

If you

 git push -u origin master

You should start tracking that remote and branch. I'm not sure if that option has always been in git.

In android.R.drawable, read more here : http://docs.since2006.com/android/2.1-drawables.php

Simple resource usage :

android:icon="@android:drawable/ic_menu_save"

Simple Java usage :

myMenuItem.setIcon(android.R.drawable.ic_menu_save);

In the build.gradle file for your app module, add this to the defaultConfig section (under the android section). This will write out the schema to a schemas subfolder of your project folder.

javaCompileOptions {
    annotationProcessorOptions {
        arguments += ["room.schemaLocation": "$projectDir/schemas".toString()]
    }
}

Like this:

// ...

android {
    
    // ... (compileSdkVersion, buildToolsVersion, etc)

    defaultConfig {

        // ... (applicationId, miSdkVersion, etc)
        
        javaCompileOptions {
            annotationProcessorOptions {
                arguments += ["room.schemaLocation": "$projectDir/schemas".toString()]
            }
        }
    }
   
    // ... (buildTypes, compileOptions, etc)

}

// ...

You can use DSUM, which will be more flexible. Like if you want to change the name of Salesman or the Quote Month, you need not change the formula, but only some criteria cells. Please see the link below for details...Even the criteria can be formula to copied from other sheets

http://office.microsoft.com/en-us/excel-help/dsum-function-HP010342460.aspx?CTT=1

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

Sometimes you have to use @import as opposed to inline . If you are working on a complex application that has 32 or more css files and you must support IE9 there is no choice. IE9 ignores any css file after the first 31 and this includes and inline css. However, each sheet can import 31 others.

If you would like to use autocomplete all the time without having to worry about hitting Ctrl + Spacebar or your own keyboard shortcut, you can make the following adjustment in the Eclipse preferences to trigger autocomplete simply by typing several different characters:

1. Eclipse > Preferences > Java > Editor > Content Assist
2. Auto Activation > Auto activation triggers for Java
3. Enter all the characters you want to trigger autocomplete, such as the following:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._

Now any time that you type any of these characters, Eclipse will trigger autocomplete suggestions based on the context.

Make the radio component as dumb component and pass props to from parent.

import React from "react";

const Radiocomponent = ({ value, setGender }) => ( 
  <div onChange={setGender.bind(this)}>
    <input type="radio" value="MALE" name="gender" defaultChecked={value ==="MALE"} /> Male
    <input type="radio" value="FEMALE" name="gender" defaultChecked={value ==="FEMALE"}/> Female
  </div>
);

export default Radiocomponent;

It's additional information, and isn't an answer.

In C++11 you can write:

for (auto& it : s) {
    cout << it << endl;
}

instead of

for (auto it = s.begin(); it != s.end(); it++) {
    cout << *it << endl;
}

It has the same meaning.

Update: See the @Alnitak's comment also.

As far as I know, currently (Android Studio 2.3) there is no way to do this.

As per Android Studio documentation:

"Note: Only one debugger can be connected to your device at a time."

When you attempt to connect Android Device Monitor it disconnects Android Studio's debug session and vice versa, when you attempt to connect Android Studio's debugger, it disconnects Android Device Monitor.

Fortunately the new version of Android Studio (3.0) will feature a Device File Explorer that will allow you to pull files from within Android Studio without the need to open the Android Device Monitor which should resolve the problem.

You have to use HTML in your webView in this case. I solved this using following code

webView.loadDataWithBaseURL(null,
                "<!DOCTYPE html><html><body style = \"text-align:center\"><img src= "
                        + \"http://www.koenvangorp.be/photos/2005_09_16-moon_2000.jpg\"
                        + " alt=\"pageNo\" width=\"100%\"></body></html>",
                "text/html", "UTF-8", null);

struct node{
    int position;
    char name[30];
    struct node * next;
};

void free_list(node * list){
    node* next_node;

    printf("\n\n Freeing List: \n");
    while(list != NULL)
    {
        next_node = list->next;
        printf("clear mem for: %s",list->name);
        free(list);
        list = next_node;
        printf("->");
    }
}

If you just want to remove any duplicate paths, I use this script I wrote a while back since I was having trouble with multiple perl5/bin paths:

#!/bin/bash
#
# path-cleanup
#
# This must be run as "source path-cleanup" or ". path-cleanup"
# so the current shell gets the changes.

pathlist=`echo $PATH | sed 's/:/\n/g' | uniq`

# echo "Starting PATH: $PATH"
# echo "pathlist: $pathlist"
unset PATH
# echo "After unset, PATH: $PATH"
for dir in $pathlist
do
    if test -d $dir ; then
        if test -z $PATH; then
            PATH=$dir
        else
            PATH=$PATH:$dir
        fi
    fi
done
export PATH
# echo "After loop, PATH: $PATH"

And I put it in my ~/.profile at the end. Since I use BASH almost exclusively, I haven't tried it in other shells.

For Linux, "ps aux | grep kafka" see if kafka properties are shown in the results. E.g. /path/to/kafka/server.properties

%s indicates a conversion type of string when using python's string formatting capabilities. More specifically, %s converts a specified value to a string using the str() function. Compare this with the %r conversion type that uses the repr() function for value conversion.

Take a look at the docs for string formatting.

Maybe you'll also want decimal separator? Here is a function I just made:

function formatFloat(num,casasDec,sepDecimal,sepMilhar) {
    if (num < 0)
    {
        num = -num;
        sinal = -1;
    } else
        sinal = 1;
    var resposta = "";
    var part = "";
    if (num != Math.floor(num)) // decimal values present
    {
        part = Math.round((num-Math.floor(num))*Math.pow(10,casasDec)).toString(); // transforms decimal part into integer (rounded)
        while (part.length < casasDec)
            part = '0'+part;
        if (casasDec > 0)
        {
            resposta = sepDecimal+part;
            num = Math.floor(num);
        } else
            num = Math.round(num);
    } // end of decimal part
    while (num > 0) // integer part
    {
        part = (num - Math.floor(num/1000)*1000).toString(); // part = three less significant digits
        num = Math.floor(num/1000);
        if (num > 0)
            while (part.length < 3) // 123.023.123  if sepMilhar = '.'
                part = '0'+part; // 023
        resposta = part+resposta;
        if (num > 0)
            resposta = sepMilhar+resposta;
    }
    if (sinal < 0)
        resposta = '-'+resposta;
    return resposta;
}

If you are using cpp11 (enable with the -std=c++0x flag if needed), then you can simply initialize the vector like this:

// static std::vector<std::string> v;
v = {"haha", "hehe"};

If it is asking you for a username and password, your origin remote is pointing at the HTTPS URL rather than the SSH URL.

Change it to ssh.

For example, a GitHub project like Git will have an HTTPS URL:

https://github.com/<Username>/<Project>.git

And the SSH one:

[email protected]:<Username>/<Project>.git

You can do:

git remote set-url origin [email protected]:<Username>/<Project>.git

to change the URL.
