If you have an empty table the Export method won't work. As a workaround. I used the Table View of Oracle SQL Developer. and clicked on Columns. Sorted by Nullable so NO was on top. And then selected these non nullable values using shift + select for the range.

This allowed me to do one base insert. So that Export could prepare a proper all columns insert.

$ git clone --bare https://github.com/example

This command will make the new "example" directory itself the $GIT_DIR (instead of example/.git). Also the branch heads at the remote are copied directly to corresponding local branch heads, without mapping. When this option is used, neither remote-tracking branches nor the related configuration variables are created.

$ git clone --mirror https://github.com/example

As with a bare clone, a mirrored clone includes all remote branches and tags, but all local references (including remote-tracking branches, notes etc.) will be overwritten each time you fetch, so it will always be the same as the original repository.

You can use finally to make sure files or resources are closed or released regardless of whether an exception occurs, even if you don't catch the exception. (Or if you don't catch that specific exception.)

myfile = open("test.txt", "w")

try:
    myfile.write("the Answer is: ")
    myfile.write(42)   # raises TypeError, which will be propagated to caller
finally:
    myfile.close()     # will be executed before TypeError is propagated

In this example you'd be better off using the with statement, but this kind of structure can be used for other kinds of resources.

A few years later, I wrote a blog post about an abuse of finally that readers may find amusing.

I think that you only have to replace SHA1 function with SHA256 function with tatk code from link in Your post

You can define a variable @Result to fill your data in it

DECLARE @Result AS INT

IF EXISTS (SELECT * FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
SET @Result = 1 
else
SET @Result = 2

I wouldn't try to temporarily enable a deprecated feature. According to the MDN documentation for showModalDialog, there's already a polyfill available on Github.

I just used that to add windows.showModalDialog to a legacy enterprise application as a userscript, but you can obviously also add it in the head of the HTML if you have access to the source.

I just learned the comm command from this thread, but wanted to add something extra: if the files are not sorted, and you don't want to touch the original files, you can pipe the outptut of the sort command. This leaves the original files intact. Works in bash, I can't say about other shells.

comm -1 -2 <(sort file1) <(sort file2)

This can be extended to compare command output, instead of files:

comm -1 -2 <(ls /dir1 | sort) <(ls /dir2 | sort)

It's about how much type-safety you want to impose.

When you write (bar) foo (which is equivalent to reinterpret_cast<bar> foo if you haven't provided a type conversion operator) you are telling the compiler to ignore type safety, and just do as it's told.

When you write static_cast<bar> foo you are asking the compiler to at least check that the type conversion makes sense and, for integral types, to insert some conversion code.

EDIT 2014-02-26

I wrote this answer more than 5 years ago, and I got it wrong. (See comments.) But it still gets upvotes!

Error shows that script does not exists

The file does not exists. check your full path

C:\Windows\TEMP\hudson6299483223982766034.sh
The system cannot find the file specified

Moreover, to launch .sh scripts into windows, you need to have CYGWIN installed and well configured into your path

Confirm that script exists.

Into jenkins script, do the following to confirm that you do have the file

cd C:\Windows\TEMP\
ls -rtl
sh -xe hudson6299483223982766034.sh

You need to put an actual tab character after the -t\ and to do that in a shell you hit ctrl-v and then the tab character. Most shells I've used support this mode of literal tab entry.

Beware, though, because copying and pasting from another place generally does not preserve tabs.

If you are trying to install in MAC , just unzip the Oracle client which you downloaded and place it into the folder where you written python scripts. it will start working.

There is too much problem of setting up environmental variables. It worked for me.

Hope this helps.

Thanks

you just need to give focus to the next input field (by invoking focus()method on that input element), for example if you're using jQuery this code will simulate the tab key when enter is pressed:

var inputs = $(':input').keypress(function(e){ 
    if (e.which == 13) {
       e.preventDefault();
       var nextInput = inputs.get(inputs.index(this) + 1);
       if (nextInput) {
          nextInput.focus();
       }
    }
});

This is the code I have for moving an item down one place in a list:

if (this.folderImages.SelectedIndex > -1 && this.folderImages.SelectedIndex < this.folderImages.Items.Count - 1)
{
    string imageName = this.folderImages.SelectedItem as string;
    int index = this.folderImages.SelectedIndex;

    this.folderImages.Items.RemoveAt(index);
    this.folderImages.Items.Insert(index + 1, imageName);
    this.folderImages.SelectedIndex = index + 1;
 }

and this for moving it one place up:

if (this.folderImages.SelectedIndex > 0)
{
    string imageName = this.folderImages.SelectedItem as string;
    int index = this.folderImages.SelectedIndex;

    this.folderImages.Items.RemoveAt(index);
    this.folderImages.Items.Insert(index - 1, imageName);
    this.folderImages.SelectedIndex = index - 1;
}

folderImages is a ListBox of course so the list is a ListBox.ObjectCollection, not a List<T>, but it does inherit from IList so it should behave the same. Does this help?

Of course the former only works if the selected item is not the last item in the list and the latter if the selected item is not the first item.

Using Windows Command Prompt:

rmdir /s /q folder

Using Powershell:

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

Note that in more cases del and rmdir wil leave you with leftover files, where Powershell manages to delete the files.

If you support IE, for versions of Internet Explorer 8 and above, this:

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />

Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.

If you separate with semi-colon, it sets compatibility levels for different versions. For example:

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:

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

This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

For this:

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

It forces the browser the render at whatever the most recent version's standards are.

For more information, there is plenty to read about on MSDN,

Dynamically changing searches based on the given parameters is a complicated subject and doing it one way over another, even with only a very slight difference, can have massive performance implications. The key is to use an index, ignore compact code, ignore worrying about repeating code, you must make a good query execution plan (use an index).

Read this and consider all the methods. Your best method will depend on your parameters, your data, your schema, and your actual usage:

Dynamic Search Conditions in T-SQL by by Erland Sommarskog

The Curse and Blessings of Dynamic SQL by Erland Sommarskog

If you have the proper SQL Server 2008 version (SQL 2008 SP1 CU5 (10.0.2746) and later), you can use this little trick to actually use an index:

Add OPTION (RECOMPILE) onto your query, see Erland's article, and SQL Server will resolve the OR from within (@LastName IS NULL OR LastName= @LastName) before the query plan is created based on the runtime values of the local variables, and an index can be used.

This will work for any SQL Server version (return proper results), but only include the OPTION(RECOMPILE) if you are on SQL 2008 SP1 CU5 (10.0.2746) and later. The OPTION(RECOMPILE) will recompile your query, only the verison listed will recompile it based on the current run time values of the local variables, which will give you the best performance. If not on that version of SQL Server 2008, just leave that line off.

CREATE PROCEDURE spDoSearch
    @FirstName varchar(25) = null,
    @LastName varchar(25) = null,
    @Title varchar(25) = null
AS
    BEGIN
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
                (@FirstName IS NULL OR (FirstName = @FirstName))
            AND (@LastName  IS NULL OR (LastName  = @LastName ))
            AND (@Title     IS NULL OR (Title     = @Title    ))
        OPTION (RECOMPILE) ---<<<<use if on for SQL 2008 SP1 CU5 (10.0.2746) and later

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

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

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

Conda itself provides a quite detailed guidance about installing non-conda packages. Details can be found here: https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-pkgs.html

The basic idea is to use conda-forge. If it doesn't work, activate the environment and use pip.

Alternatively, db.rawQuery(sql, selectionArgs) exists.

Cursor c = db.rawQuery(select, null);

this.props.history.push("/url")

If you have not found this.props.history available in your component , then try this

import {withRouter} from 'react-router-dom'
export default withRouter(MyComponent)  

You are trying to execute an asynchronous function in a synchronous way, which is unfortunately not possible in Javascript.

As you guessed correctly, the roomId=results.... is executed when the loading from the DB completes, which is done asynchronously, so AFTER the resto of your code is completed.

Look at this article, it talks about .insert and not .find, but the idea is the same : http://metaduck.com/01-asynchronous-iteration-patterns.html

I believe that your problem is that you're checking for an empty string using double quotes instead of single quotes. Try just changing to:

DELETE FROM table WHERE edit_user=''

For whatever reason, the Scanner class also issues this same exception if it encounters special characters it cannot read. Beyond using the hasNextLine() method before each call to nextLine(), make sure the correct encoding is passed to the Scanner constructor, e.g.:

Scanner scanner = new Scanner(new FileInputStream(filePath), "UTF-8");

Given input in seconds you can transform to format hh:mm:ss like this :

int hours;
int minutes;
int seconds;
int formatHelper;

int input;


//formatHelper maximum value is 24 hours represented in seconds

formatHelper = input % (24*60*60);

//for example let's say format helper is 7500 seconds

hours = formatHelper/60*60;
minutes = formatHelper/60%60;
seconds = formatHelper%60;

//now operations above will give you result = 2hours : 5 minutes : 0 seconds;

I have used formatHelper since the input can be more then 86 400 seconds, which is 24 hours.

If you want total time of your input represented by hh:mm:ss, you can just avoid formatHelper.

I hope it helps.

This is what I would do

    public static double convertToDouble(String temp){
       String a = temp;
       //replace all commas if present with no comma
       String s = a.replaceAll(",","").trim(); 
      // if there are any empty spaces also take it out.          
      String f = s.replaceAll(" ", ""); 
      //now convert the string to double
      double result = Double.parseDouble(f); 
    return result; // return the result
}

For example you input the String "4 55,63. 0 " the output will the double number 45563.0

To avoid that issue, when incrementing time you should convert back to UTC and then add or subtract.

This way you will be able to walk through any periods where hours or minutes happen twice.

If you converted to UTC, add each second, and convert to local time for display. You would go through 11:54:08 p.m. LMT - 11:59:59 p.m. LMT and then 11:54:08 p.m. CST - 11:59:59 p.m. CST.

Add this to your python script.

import os
os.system("exec /path/to/another/script")

This executes that command as if it were typed into the shell.

You may be adding the onclick handler as inline markup:

<input id="addreport" type="button" value="Add New Report" onclick="openAdd()" />

If so, the jquery .off() or .unbind() won't work. You need to add the original event handler in jquery as well:

$("#addreport").on("click", "", function (e) {
   openAdd();
});

Then the jquery has a reference to the event handler and can remove it:

$("#addreport").off("click")

VoidKing mentions this a little more obliquely in a comment above.

No, you cannot. But you can create a user defined table function.

If you want to list folders and files like graphical directory tree, you should use tree command.

tree /f

There are various options for display format or ordering.

Check example output.

Answering late. Hope it help someone.

Simply use the graph API with this url format: https://graph.facebook.com/[email protected]&type=user&access_token=... You can easily create an application here and grab an access token for it here. I believe you get an estimated 600 requests per 600 seconds, although this isn't documented.

If you are doing this in bulk, you could use batch requests in batches of 20 email addresses. This may help with rate limits (I am not sure if you get 600 batch requests per 600 seconds or 600 individual requests).

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=
    (MyclassFragment)getSupportFragmentManager().findFragmentById(R.id.idFragment);

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

if you are using sql server, use brackets or single quotes around alias name in a query you have in code.

If @Maleki's answer isn't working for you, check and see if you have an .editorconfig file in your project folder.

For example the Angular CLI generates one with a new project that looks like this

# Editor configuration, see http://editorconfig.org
root = true

[*]
charset = utf-8
indent_style = space
indent_size = 2
insert_final_newline = true
trim_trailing_whitespace = true

[*.md]
max_line_length = off
trim_trailing_whitespace = false

Changing the indent_size here is required as it seems it will override anything in your .vscode workspace or user settings.

You need to wait for Javascript and jQuery to finish loading. Execute Javascript to check if jQuery.active is 0 and document.readyState is complete, which means the JS and jQuery load is complete.

public boolean waitForJStoLoad() {

    WebDriverWait wait = new WebDriverWait(driver, 30);

    // wait for jQuery to load
    ExpectedCondition<Boolean> jQueryLoad = new ExpectedCondition<Boolean>() {
      @Override
      public Boolean apply(WebDriver driver) {
        try {
          return ((Long)executeJavaScript("return jQuery.active") == 0);
        }
        catch (Exception e) {
          return true;
        }
      }
    };

    // wait for Javascript to load
    ExpectedCondition<Boolean> jsLoad = new ExpectedCondition<Boolean>() {
      @Override
      public Boolean apply(WebDriver driver) {
        return executeJavaScript("return document.readyState")
            .toString().equals("complete");
      }
    };

  return wait.until(jQueryLoad) && wait.until(jsLoad);
}

Just a little addition: I believe it's a common and known thing to add exit; after the header function in case we don't want the rest of the code to load or execute...

header('Location: ' . $_SERVER['HTTP_REFERER']);
exit;

I've seen:

hasattr(s, 'endswith') 

First, create an environment file that will have all the key-value pair of the environments like below and named it whatever you like in my case its env_var.env

MINIENTREGA_FECHALIMITE="2011-03-31"
MINIENTREGA_FICHEROS="informe.txt programa.c"
MINIENTREGA_DESTINO="./destino/entrega-prac1"

Then create a script that will export all the environment variables for the python environment like below and name it like export_env.sh

#!/usr/bin/env bash

ENV_FILE="$1"
CMD=${@:2}

set -o allexport
source $ENV_FILE
set +o allexport

$CMD

This script will take the first argument as the environment file then export all the environment variable in that file and then run the command after that.

USAGE:

./export_env.sh env_var.env python app.py

This is my working solution

View view = new View(getApplicationContext());
view.setBackgroundResource(R.color.background);
myEditText.setBackground(view.getBackground());

Here is a one liner version of linux "touch" in Windows

c:\<folder>\break > .gitignore

that will create a blank .gitignore file where you can edit and add items to ignore

C:\Users\test>dir .gitignore
 Volume in drive C is Windows
 Volume Serial Number is 9223-E93F

 Directory of C:\Users\test

18/04/2019  02:23 PM                 0 .gitignore
               1 File(s)              0 bytes
               0 Dir(s)  353,009,770,496 bytes free

Here is code to get line number and column position

function getLineNumber(tArea) {

    return tArea.value.substr(0, tArea.selectionStart).split("\n").length;
}

function getCursorPos() {
    var me = $("textarea[name='documenttext']")[0];
    var el = $(me).get(0);
    var pos = 0;
    if ('selectionStart' in el) {
        pos = el.selectionStart;
    } else if ('selection' in document) {
        el.focus();
        var Sel = document.selection.createRange();
        var SelLength = document.selection.createRange().text.length;
        Sel.moveStart('character', -el.value.length);
        pos = Sel.text.length - SelLength;
    }
    var ret = pos - prevLine(me);
    alert(ret);

    return ret; 
}

function prevLine(me) {
    var lineArr = me.value.substr(0, me.selectionStart).split("\n");

    var numChars = 0;

    for (var i = 0; i < lineArr.length-1; i++) {
        numChars += lineArr[i].length+1;
    }

    return numChars;
}

tArea is the text area DOM element

I would not recommend utilizing the Grid system in this instance, as much as simply adding an increased padding for each <h2>. That being said, the way you would achieve this using col-*-offset-* would be as follows:

<div class="jumbotron">
    <div class="container">
        <div class="row">
            <div class="col-md-12">
                <h2>One</h2>
            </div>

            <div class="col-md-11 col-md-offset-1">
                <h2>Two</h2>
            </div>

            <div class="col-md-10 col-md-offset-2">
                <h2>Three</h2>
            </div>
        </div>
    </div>
</div>

Essentially the first line must span the entire row (so -12). The second line must be offset by 1 column, so you offset by 1 and give it a total width of 11 columns (11+1 = 12) and so forth. Your offset is always enough to ensure that the total column count equals 12.

As it has been outlined here, because Google is sending an "X-Frame-Options: SAMEORIGIN" response header you cannot simply set the src to "http://www.google.com" in a iframe.

If you want to embed Google into an iframe you can do what sudopeople suggested in a comment above and use a Google custom search link like the following. This worked great for me (left 'q=' blank to start with blank search).

<iframe id="if1" width="100%" height="254" style="visibility:visible" src="http://www.google.com/custom?q=&btnG=Search"></iframe>

EDIT:

This answer no longer works. For information, and instructions on how to replace an iframe search with a google custom search element check out: https://support.google.com/customsearch/answer/2641279

In C, the compiler can generally optimize them to be the same if the result is unused.

However, in C++ if using other types that provide their own ++ operators, the prefix version is likely to be faster than the postfix version. So, if you don't need the postfix semantics, it is better to use the prefix operator.

I like daggett answer but there is another solution you can get try if your file is not big enough.

$file = __FILE__; // Let's take the current file just as an example.

$start_line = __LINE__ -1; // The same with the line what we look for. Take the line number where $line variable is declared as the start.

$lines_to_display = 5; // The number of lines to display. Displays only the $start_line if set to 1. If $lines_to_display argument is omitted displays all lines starting from the $start_line.

echo implode('', array_slice(file($file), $start_line, lines_to_display));

npm link webpack worked for me.

My webpack configuration: "webpack": "^4.41.2", "webpack-dev-server": "^3.9.0", "webpack-cli": "^3.3.10"

evict non ISO-8859-1 characters, will be replace by '?' (before send to a ISO-8859-1 DB by example):

utf8String = new String ( utf8String.getBytes(), "ISO-8859-1" );

If you pass a reference to the (concrete subclass of) fragment into the async task, you can then access the fragment directly.

Some ways of passing the fragment reference into the async task:

• If your async task is a fully fledged class (class FooTask extends AsyncTask), then pass your fragment into the constructor.
• If your async task is an inner class, just declare a final Fragment variable in the scope the async task is defined, or as a field of the outer class. You'll be able to access that from the inner class.

Try this

var d = new Date();
d.setDate(d.getDate() - 1);

JSON itself has no date format, it does not care how anyone stores dates. However, since this question is tagged with javascript, I assume you want to know how to store javascript dates in JSON. You can just pass in a date to the JSON.stringify method, and it will use Date.prototype.toJSON by default, which in turns uses Date.prototype.toISOString (MDN on Date.toJSON):

const json = JSON.stringify(new Date());
const parsed = JSON.parse(json); //2015-10-26T07:46:36.611Z
const date = new Date(parsed); // Back to date object

I also found it useful to use the reviver parameter of JSON.parse (MDN on JSON.parse) to automatically convert ISO strings back to javascript dates whenever I read JSON strings.

const isoDatePattern = new RegExp(/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+([+-][0-2]\d:[0-5]\d|Z)/);

const obj = {
 a: 'foo',
 b: new Date(1500000000000) // Fri Jul 14 2017, etc...
}
const json = JSON.stringify(obj);

// Convert back, use reviver function:
const parsed = JSON.parse(json, (key, value) => {
    if (typeof value === 'string' &&  value.match(isoDatePattern)){
        return new Date(value); // isostring, so cast to js date
    }
    return value; // leave any other value as-is
});
console.log(parsed.b); // // Fri Jul 14 2017, etc...

The different approaches discussed in the previous answers are based on the assumption that either the user knows column indices to drop or subset on, or the user wishes to subset a dataframe using a range of columns (for instance between 'C' : 'E').

pandas.DataFrame.drop() is certainly an option to subset data based on a list of columns defined by user (though you have to be cautious that you always use copy of dataframe and inplace parameters should not be set to True!!)

Another option is to use pandas.columns.difference(), which does a set difference on column names, and returns an index type of array containing desired columns. Following is the solution:

df = pd.DataFrame([[2,3,4], [3,4,5]], columns=['a','b','c'], index=[1,2])
columns_for_differencing = ['a']
df1 = df.copy()[df.columns.difference(columns_for_differencing)]
print(df1)

The output would be:

    b   c
1   3   4
2   4   5

There appears to be a bug with appendTo using a frameset ID appending to a FORM in Chrome. Swapped out the attribute type directly with div and it works.

A bit longer than I expected:

>>> df
                samples  subject  trial_num
0  [-0.07, -2.9, -2.44]        1          1

>>>
>>> s = df.apply(lambda x: pd.Series(x['samples']),axis=1).stack().reset_index(level=1, drop=True)
>>> s.name = 'sample'

5        2          3   -1.79

If you want sequential index, you can apply reset_index(drop=True) to the result.

update:

>>> res = df.set_index(['subject', 'trial_num'])['samples'].apply(pd.Series).stack()
>>> res = res.reset_index()
>>> res.columns = ['subject','trial_num','sample_num','sample']
>>> res
    subject  trial_num  sample_num  sample

How do I have to do in Python for calling an static method from another static method of the same class?

class Test() :
    @staticmethod
    def static_method_to_call()
        pass

    @staticmethod
    def another_static_method() :
        Test.static_method_to_call()

    @classmethod
    def another_class_method(cls) :
        cls.static_method_to_call()

You need to check one if you have two

if(rbMale.Checked)
{

}
else
{

}

You need to check all the checkboxes if more then two

if(rb1.Checked)
{

}
else if(rb2.Checked)
{

}
else if(rb3.Checked)
{

}

First, reset any changes

This will undo any changes you've made to tracked files and restore deleted files:

git reset HEAD --hard

Second, remove new files

This will delete any new files that were added since the last commit:

git clean -fd

Files that are not tracked due to .gitignore are preserved; they will not be removed

Warning: using -x instead of -fd would delete ignored files. You probably don't want to do this.

First, give all your links a unique id and make a css class called active:

<ul>
    <li><a id="link1" href="#/...">link 1</a></li>
    <li><a id="link2" href="#/...">link 2</a></li>
</ul>

CSS:

.active {
    font-weight: bold;
}

Jquery version:

function setActiveLink(setActive){
    if ($("a").hasClass('active'))
        $("a").removeClass('active');
    if (setActive)
        $("#"+setActive).addClass('active');
}

$(function() {
    $("a").click(function() {
        setActiveLink(this.id);
    });
});

Vanilla javascript version:

In order to prevent selecting too many links with document.querySelectorAll, give the parent element an id called menuLinks. Add an onClick handler on the links.

<ul id="menuLinks">
    <li><a id="link1" href="#/..." onClick="setActiveLink(this.id);">link 1</a></li>
    <li><a id="link2" href="#/..." onClick="setActiveLink(this.id);">link 2</a></li>
</ul>

Code:

function setActiveLink(setActive){
    var links = document.querySelectorAll("#menuLinks a");
    Array.prototype.map.call(links, function(e) {
        e.className = "";
        if (e.id == setActive)
            e.className = "active";
    })
}

You need to set the correct content type and stringify your object.

var arr = {City:'Moscow', Age:25};
$.ajax({
    url: "Ajax.ashx",
    type: "POST",
    data: JSON.stringify(arr),
    dataType: 'json',
    async: false,
    contentType: 'application/json; charset=utf-8',
    success: function(msg) {
        alert(msg);
    }
});

You can prepend an @: $content = @file_get_contents($site);

This will supress any warning - use sparingly!. See Error Control Operators

Edit: When you remove the 'http://' you're no longer looking for a web page, but a file on your disk called "www.google....."

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

Under the connection properties, uncheck "Enable background refresh". This will make the connection refresh when told to, not in the background as other processes happen.

With background refresh disabled, your VBA procedure will wait for your external data to refresh before moving to the next line of code.

Then you just modify the following code:

ActiveWorkbook.Connections("CONNECTION_NAME").Refresh
Sheets("SHEET_NAME").PivotTables("PIVOT_TABLE_NAME").PivotCache.Refresh

You can also turn off background refresh in VBA:

ActiveWorkbook.Connections("CONNECTION_NAME").ODBCConnection.BackgroundQuery = False

the core functions are getBytes(String charset) and new String(byte[] data). you can use these functions to do UTF-8 decoding.

UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String() is the byte array, which calling is equal to new String(bytes, "UTF-8")

Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.

The decoding sentence should be

String decoded = new String(encoded.getBytes("ISO-8859-1"));

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

File -> Export -> Web -> WAR file

OR in Kepler follow as shown below :

Easiest solution is to add onWheel={ event => event.currentTarget.blur() }} on input itself.

I ran into a problem with this as well as my JUnit assertEquals were failing comparing Dates to Hibernate emitted 'java.util.Date' types (which as described in the question are really Timestamps). It turns out that by changing the mapping to 'date' rather than 'java.util.Date' Hibernate generates java.util.Date members. I am using an XML mapping file with Hibernate version 4.1.12.

This version emits 'java.util.Timestamp':

<property name="date" column="DAY" type="java.util.Date" unique-key="KONSTRAINT_DATE_IDX" unique="false" not-null="true" />

This version emits 'java.util.Date':

<property name="date" column="DAY" type="date" unique-key="KONSTRAINT_DATE_IDX" unique="false" not-null="true" />

Note, however, if Hibernate is used to generate the DDL, then these will generate different SQL types (Date for 'date' and Timestamp for 'java.util.Date').

Make sure the folder you have created inside htdocs are present there and you browse the right url.

for example

localhost/yoursitename

make sure yoursitename folder is present

If I remember from your previous questions, you're binding to a DataTable. Try this:

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

    DataTable sourceData = (DataTable)GridView1.DataSource;

    sourceData.Rows[e.RowIndex].Delete();

    GridVie1.DataSource = sourceData;
    GridView1.DataBind();
}

Essentially, as I said in my comment, grab a copy of the GridView's DataSource, remove the row from it, then set the DataSource to the updated object and call DataBind() on it again.

If you have many factor variables, you can use select_if funtion. install the dplyr packages. There are many function that separates data by satisfying a condition. you can set the conditions.

Use like this.

categorical<-select_if(df,is.factor)
str(categorical)

I know its too late now. However even today if you are having trouble accessing cross thread controls? This is the shortest answer till date :P

Invoke(new Action(() =>
                {
                    label1.Text = "WooHoo!!!";
                }));

This is how i access any form control from a thread.

More Info on ValidationSettings:UnobtrusiveValidationMode

Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.

Type: UnobtrusiveValidationMode

Default value: None

Remarks: If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic. If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic.

Example:

    <appSettings>
      <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
    </appSettings>

One idea is to use String... args

public class Sample {
   void demoMethod(String... args) {
      for (String arg : args) {
         System.out.println(arg);
      }
   }
   public static void main(String args[] ) {
      new Sample().demoMethod("ram", "rahim", "robert");
      new Sample().demoMethod("krishna", "kasyap");
      new Sample().demoMethod();
   }
}

Output

ram
rahim
robert
krishna
kasyap

Try this: Stretchy Sprites - Cross-browser, responsive resizing/stretching of CSS sprite images

This method scales sprites 'responsively' so that the width/height adjust according to your browser window size. It doesn't use background-size as support for this in older browsers is non-existent.

CSS

.stretchy {display:block; float:left; position:relative; overflow:hidden; max-width:160px;}
.stretchy .spacer {width: 100%; height: auto;}
.stretchy .sprite {position:absolute; top:0; left:0; max-width:none; max-height:100%;}
.stretchy .sprite.s2 {left:-100%;}
.stretchy .sprite.s3 {left:-200%;}

HTML

<a class="stretchy" href="#">
  <img class="spacer" alt="" src="spacer.png">
  <img class="sprite" alt="icon" src="sprite_800x160.jpg">
</a>
<a class="stretchy s2" href="#">
  <img class="spacer" alt="" src="spacer.png">
  <img class="sprite" alt="icon" src="sprite_800x160.jpg">
</a>
<a class="stretchy s3" href="#">
  <img class="spacer" alt="" src="spacer.png">
  <img class="sprite" alt="icon" src="sprite_800x160.jpg">
</a>

Java strings have .startsWith() and .contains() methods which will get you most of the way. For anything more complicated you'd have to use regex or write your own method.

Use this snippet

import os
import requests
url = 'http://host:port/endpoint'
with open(path_img, 'rb') as img:
  name_img= os.path.basename(path_img)
  files= {'image': (name_img,img,'multipart/form-data',{'Expires': '0'}) }
  with requests.Session() as s:
    r = s.post(url,files=files)
    print(r.status_code)

So we make a function that takes in a literal string, and the array we want to look through. it returns a new array with the matches found. We create a new regexp object inside this function and then execute a String.search on each element element in the array. If found, it pushes the string into a new array and returns.

// literal_string: a regex search, like /thisword/ig
// target_arr: the array you want to search /thisword/ig for.

function arr_grep(literal_string, target_arr) {
  var match_bin = [];
  // o_regex: a new regex object.
  var o_regex = new RegExp(literal_string);
  for (var i = 0; i < target_arr.length; i++) {
    //loop through array. regex search each element.
    var test = String(target_arr[i]).search(o_regex);
    if (test > -1) {
    // if found push the element@index into our matchbin.
    match_bin.push(target_arr[i]);
    }
  }
  return match_bin;
}

// arr_grep(/.*this_word.*/ig, someArray)

If you like to call an activity method from within a custom layout class(non-Activity Class).You should create a delegate using interface.

It is untested and i coded it right . but i am conveying a way to achieve what you want.

First of all create and Interface

interface TaskCompleteListener<T> {
   public void onProfileClicked(T result);
}



public class ProfileView extends LinearLayout
{
    private TaskCompleteListener<String> callback;
    TextView profileTitleTextView;
    ImageView profileScreenImageButton;
    boolean isEmpty;
    ProfileData data;
    String name;

    public ProfileView(Context context, AttributeSet attrs, String name, final ProfileData profileData)
    {
        super(context, attrs);
        ......
        ......
    }
    public setCallBack( TaskCompleteListener<String> cb) 
    {
      this.callback = cb;
    }
    //Heres where things get complicated
    public void onClick(View v)
    {
        callback.onProfileClicked("Pass your result or any type");
    }
}

And implement this to any Activity.

and call it like

ProfileView pv = new ProfileView(actvitiyContext, null, temp, tempPd);
pv.setCallBack(new TaskCompleteListener
               {
                   public void onProfileClicked(String resultStringFromProfileView){}
               });

1) Update Devise so that it can handle Rails 4.0 by adding this line to your application's Gemfile:

gem 'devise', '3.0.0.rc' 

Then execute:

$ bundle

2) Add the old functionality of attr_accessible again to rails 4.0

Try to use attr_accessible and don't comment this out.

Add this line to your application's Gemfile:

gem 'protected_attributes'

Then execute:

$ bundle

Actually i am getting return value from a another sp into @temp and then it @temp =1 then i want to inc the count of @SelectoneCount by 1 and so on. Please let me know what is the correct syntax.

What's wrong with:

IF @Temp = 1 --Or @Temp = 2 also?
BEGIN
    SET @SelectoneCount = @SelectoneCount + 1
END

(Although this does reek of being procedural code - not usually the best way to use SQL)

There 3 functions you want to look at here:

• LARGE - Returns the k-th largest value in a data set.
• INDEX - Returns a value or the reference to a value from within a table or range.
• MATCH - The MATCH function searches for a specified item in a range of cells, and then returns the relative position of that item in the range.

I ran a sample in Excel with your OPS values in Column B and Players in Column C, see below:

• In Cells A13 to A17, the values 1 to 5 were inserted to specify the nth highest value.
• In Cell B13, the following formula was added: =LARGE($B$2:$B$11, A13)
• In Cell C13, the following formula was added: =INDEX($C$2:$C$11,MATCH(B13,$B$2:$B$11,0))
• These formulae get the highest ranking OPS and Player based on the value in A13.
• Simply select and drag to copy these formulae down to the next 4 cells which will reference the corresponding ranking in Column A.

Code for your reference:

#include <iomanip>
#include <sstream>
...
string intToHexString(int intValue) {

    string hexStr;

    /// integer value to hex-string
    std::stringstream sstream;
    sstream << "0x"
            << std::setfill ('0') << std::setw(2)
    << std::hex << (int)intValue;

    hexStr= sstream.str();
    sstream.clear();    //clears out the stream-string

    return hexStr;
}

Late to the party, but the tsbox package is designed to perform conversions like this. To convert your data into a ts-object, you can do:

dta <- data.frame(
  Dates = c("3/14/2013", "3/15/2013", "3/18/2013", "3/19/2013"),
  Bajaj_close = c(1854.8, 1850.3, 1812.1, 1835.9),
  Hero_close = c(1669.1, 1684.45, 1690.5, 1645.6)
)

dta
#>       Dates Bajaj_close Hero_close
#> 1 3/14/2013      1854.8    1669.10
#> 2 3/15/2013      1850.3    1684.45
#> 3 3/18/2013      1812.1    1690.50
#> 4 3/19/2013      1835.9    1645.60

library(tsbox)
ts_ts(ts_long(dta))
#> Time Series:
#> Start = 2013.1971293045 
#> End = 2013.21081883954 
#> Frequency = 365.2425 
#>          Bajaj_close Hero_close
#> 2013.197      1854.8    1669.10
#> 2013.200      1850.3    1684.45
#> 2013.203          NA         NA
#> 2013.205          NA         NA
#> 2013.208      1812.1    1690.50
#> 2013.211      1835.9    1645.60

It automatically parses the dates, detects the frequency and makes the missing values at the weekends explicit. With ts_<class>, you can convert the data to any other time series class.

I think this is a simple code in java which will show the string value in CSV after compile this code.

public class CsvWriter {

    public static void main(String args[]) {
        // File input path
        System.out.println("Starting....");
        File file = new File("/home/Desktop/test/output.csv");
        try {
            FileWriter output = new FileWriter(file);
            CSVWriter write = new CSVWriter(output);

            // Header column value
            String[] header = { "ID", "Name", "Address", "Phone Number" };
            write.writeNext(header);
            // Value
            String[] data1 = { "1", "First Name", "Address1", "12345" };
            write.writeNext(data1);
            String[] data2 = { "2", "Second Name", "Address2", "123456" };
            write.writeNext(data2);
            String[] data3 = { "3", "Third Name", "Address3", "1234567" };
            write.writeNext(data3);
            write.close();
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();

        }

        System.out.println("End.");

tl;dr the "standards" are a hodge-podge mess; it depends who you ask!

Overall, there appears to be no MIME type image/jpg. Yet, in practice, nearly all software handles image files named "*.jpg" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg could be many different things.

For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.

• sitepoint.com mime-types-complete-list (archived)
  • .jfif, .jfif-tbnl, .jpe, .jpeg, .jpg ? image/jpeg
  • .jfif, .jpe, .jpeg, .jpg ? image/pjpeg
• freeformatter.com mime-types (archived)
  • .jpeg, .jpg ? image/jpeg
  • .jpeg, .jpg ? image/x-citrix-jpeg
  • .pjpeg ? image/pjpeg
• IANA "Media Types" (formerly known as MIME types) lists (archived)
  (this document lists "names", not "file name extensions")
  • jpg not mentioned
  • jpeg ? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg¹³
  • JPEG ? video/JPEG
  • jpeg2000 ? video/jpeg2000
  • jpm ? image/jpm (JPEG 2000)
  • jpx ? image/jpx (JPEG 2000)
  • vnd.sealedmedia.softseal.jpg ? image/vnd.sealedmedia.softseal.jpg
• RFC 3745 MIME Type Registrations for JPEG 2000 (ISO/IEC 15444)
  • .jpg file extension not mentioned
  • .jpeg file extension not mentioned
  • .jp2, .jpg2 ? image/jp2 (JPEG 2000)⁹
  • .jpf, .jpx ? image/jpx (JPEG 2000 ISO-JPEG2000-2 encoded image data)¹⁰
  • .mj2, .mjp2 ? video/mj2 (Motion JPEG 2000)¹¹
  • .jpm, .jpgm ? image/jpm (JPEG 2000 profiles and extensions)¹²

These "complete lists" and RFC do not have MIME type image/jpg! But for MIME type image/jpeg some lists do have varying file name extensions (.jpeg, .jpg, …). Other lists do not mention image/jpeg.

Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.

Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf is preferred file extension for image/jpx but in IANA Media Types the name jpf is not present (and that IANA document references RFC 3745!).

Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.

Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?

The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg yet there exists the odd vnd.sealedmedia.softseal.jpg. File extension.JPEG is only known as a video type while file extension .jpeg is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000 is type video yet RFC 3745 considers JPEG 2000 an image type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg).

Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

There's this Explorer Exclude extension that exactly does this. https://marketplace.visualstudio.com/items?itemName=RedVanWorkshop.explorer-exclude-vscode-extension

It adds an option to hide current folder/file to the right click menu. It also adds a vertical tab Hidden Items to explorer menu where you can see currently hidden files & folders and can toggle them easily.

1. bool operator==(pos a) const{ - this method doesn't change object's elements.
2. bool operator==(pos a) { - it may change object's elements.

In my understanding, the way Android handles the MVC pattern is like:

You have an Activity, which serves as the controller. You have a class which responsibility is to get the data - the model, and then you have the View class which is the view.

When talking about the view most people think only for its visual part defined in the xml. Let's not forget that the View also has a program part with its constructors, methods and etc, defined in the java class.

Can use enumerate.

a = [1, 2, 3, 4]
b = [2, 3, 4, 5]

ab = [val * b[i] for i, val in enumerate(a)]

Now with Ruby 2.3 you can use &. operator ('lonely operator') to check for nil at the same time as accessing a value.

@person&.spouse&.name

https://en.wikibooks.org/wiki/Ruby_Programming/Syntax/Operators#Other_operators

Use #try instead so you don't have to keep checking for nil.

http://api.rubyonrails.org/classes/Object.html#method-i-try

@person.try(:spouse).try(:name)

instead of

@person.spouse.name if @person && @person.spouse

For enum type, I think this is a suitable way, and the difference between class is how to calculate hash value.

template <typename T>
struct EnumTypeHash {
  std::size_t operator()(const T& type) const {
    return static_cast<std::size_t>(type);
  }
};

enum MyEnum {};
class MyValue {};

std::unordered_map<MyEnum, MyValue, EnumTypeHash<MyEnum>> map_;

I proxy independent Node Express applications through Nginx.

Thus new applications can be easily mounted and I can also run other stuff on the same server at different locations.

Here are more details on my setup with Nginx configuration example:

Deploy multiple Node applications on one web server in subfolders with Nginx

Things get tricky with Node when you need to move your application from from localhost to the internet.

There is no common approach for Node deployment.

Google can find tons of articles on this topic, but I was struggling to find the proper solution for the setup I need.

Basically, I have a web server and I want Node applications to be mounted to subfolders (i.e. http://myhost/demo/pet-project/) without introducing any configuration dependency to the application code.

At the same time I want other stuff like blog to run on the same web server.

Sounds simple huh? Apparently not.

In many examples on the web Node applications either run on port 80 or proxied by Nginx to the root.

Even though both approaches are valid for certain use cases, they do not meet my simple yet a little bit exotic criteria.

That is why I created my own Nginx configuration and here is an extract:

upstream pet_project {
  server localhost:3000;
}

server {
  listen 80;
  listen [::]:80;
  server_name frontend;

  location /demo/pet-project {
    alias /opt/demo/pet-project/public/;
    try_files $uri $uri/ @pet-project;
  }

  location @pet-project {
    rewrite /demo/pet-project(.*) $1 break;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $proxy_host;
    proxy_set_header X-NginX-Proxy true;

    proxy_pass http://pet_project;
    proxy_redirect http://pet_project/ /demo/pet-project/;
  }
}

From this example you can notice that I mount my Pet Project Node application running on port 3000 to http://myhost/demo/pet-project.

First Nginx checks if whether the requested resource is a static file available at /opt/demo/pet-project/public/ and if so it serves it as is that is highly efficient, so we do not need to have a redundant layer like Connect static middleware.

Then all other requests are overwritten and proxied to Pet Project Node application, so the Node application does not need to know where it is actually mounted and thus can be moved anywhere purely by configuration.

proxy_redirect is a must to handle Location header properly. This is extremely important if you use res.redirect() in your Node application.

You can easily replicate this setup for multiple Node applications running on different ports and add more location handlers for other purposes.

From: http://skovalyov.blogspot.dk/2012/07/deploy-multiple-node-applications-on.html

You can try this for example, this code put the scrollbar at the bottom for all DIV tags

Remember: jQuery can accept a function instead the value as argument. "this" is the object treated by jQuery, the function returns the scrollHeight property of the current DIV "this" and do it for all DIV in the document.

$("div").scrollTop(function(){return this.scrollHeight})

This is my solution https://github.com/doridori/AndroidUtils/blob/master/App/src/main/java/com/doridori/lib/app/ActivityCounter.java

Basically involved counting the lifecycle methods for all Activity's with a timer to catch cases where there is no activity currently in the foreground but the app is (i.e. on rotation)

Using find with bind to pass specific key values to a callback function.

   function byValue(o) { 
       return o.a === this.a && o.b === this.b; 
   };   

   var result = jsObjects.find(byValue.bind({ a: 5, b: 6 }));

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

Try it ;) Just watch the content of the FrameLayout(@id/tabcontent), because I don't know how it will handle in case of scrolling... In my case it works because I used ListView as the content of my tabs. :) Hope it helps.

    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <RelativeLayout 
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent">
        <FrameLayout android:id="@android:id/tabcontent"
             android:layout_width="fill_parent" 
             android:layout_height="fill_parent"
             android:layout_alignParentTop="true" 
             android:layout_above="@android:id/tabs" />
    <TabWidget android:id="@android:id/tabs"

I have never come across a situation where one needs to call a destructor manually. I seem to remember even Stroustrup claims it is bad practice.

Cell A1 = find/the/position/of/the last slash

simple way to do it is reverse the text and then find the first slash as normal. Now you can get the length of the full text minus this number.

Like so:

=LEN(A1)-FIND("/",REVERSETEXT(A1),1)+1

This returns 21, the position of the last /

Some libraries require the updated gradle. Such as:

You should be able to use the current directory

Iterate through the array, and splice out the ones you don't want. For easier use, iterate backwards so you don't have to take into account the live nature of the array:

for (var i = myArray.length - 1; i >= 0; --i) {
    if (myArray[i].field == "money") {
        myArray.splice(i,1);
    }
}

find() takes a selector, not a value. This means you need to use it in the same way you would use the regular jQuery function ($('selector')).

Therefore you need to do something like this:

$(this).find('[value="X"]').remove();

See the jQuery find docs.

npm i ejs --force

The functionality of creating SQL Agent Jobs is not available in SQL Server Express Edition. An alternative is to execute a batch file that executes a SQL script using Windows Task Scheduler.

In order to do this first create a batch file named sqljob.bat

sqlcmd -S servername -U username -P password -i <path of sqljob.sql>

Replace the servername, username, password and path with yours.

Then create the SQL Script file named sqljob.sql

USE [databasename]
--T-SQL commands go here
GO

Replace the [databasename] with your database name. The USE and GO is necessary when you write the SQL script.

sqlcmd is a command-line utility to execute SQL scripts. After creating these two files execute the batch file using Windows Task Scheduler.

NB: An almost same answer was posted for this question before. But I felt it was incomplete as it didn't specify about login information using sqlcmd.

I know I come late, but only recently I was able to implement such "addHeader" to the Adapter. In my FlexibleAdapter project you can call setHeader on a Sectionable item, then you call showAllHeaders. If you need only 1 header then the first item should have the header. If you delete this item, then the header is automatically linked to the next one.

Unfortunately footers are not covered (yet).

The FlexibleAdapter allows you to do much more than create headers/sections. You really should have a look: https://github.com/davideas/FlexibleAdapter.

May be use like this

if($match > 0){
 $msg = 'Login Complete! Thanks';
 echo "<a href='".$link_address."'>link</a>";
 }
else{
 $msg = 'Login Failed!<br /> Please make sure that you enter the correct  details and that you have activated your account.';
}

Using param to name the parameters allows you to ignore the order of the parameters:

ParamEx.ps1

# Show how to handle command line parameters in Windows PowerShell
param(
  [string]$FileName,
  [string]$Bogus
)
write-output 'This is param FileName:'+$FileName
write-output 'This is param Bogus:'+$Bogus

ParaEx.bat

rem Notice that named params mean the order of params can be ignored
powershell -File .\ParamEx.ps1 -Bogus FooBar -FileName "c:\windows\notepad.exe"

In a loop it's harmless, but in an assignment statement it can lead to unexpected results:

var x = 5;
var y = x++; // y is now 5 and x is 6
var z = ++x; // z is now 7 and x is 7

Whitespace between the variable and the operator can lead to unexpected results as well:

a = b = c = 1; a ++ ; b -- ; c; console.log('a:', a, 'b:', b, 'c:', c)

In a closure, unexpected results can be an issue as well:

var foobar = function(i){var count = count || i; return function(){return count++;}}

baz = foobar(1);
baz(); //1
baz(); //2


var alphabeta = function(i){var count = count || i; return function(){return ++count;}}

omega = alphabeta(1);
omega(); //2
omega(); //3

And it triggers automatic semicolon insertion after a newline:

var foo = 1, bar = 2, baz = 3, alpha = 4, beta = 5, delta = alpha
++beta; //delta is 4, alpha is 4, beta is 6

preincrement/postincrement confusion can produce off-by-one errors that are extremely difficult to diagnose. Fortunately, they are also complete unnecessary. There are better ways to add 1 to a variable.

According to your example here it seems that they both reside in the same namespace, i conclude that they are both part of the same project ( if you haven't created another project with the same namespace) and all class by default are defined as internal to the project they are defined in, if haven't declared otherwise, therefore i guess the problem is that your file is not included in your project. You can include it by right clicking the file in the solution explorer window => Include in project, if you cannot see the file inside the project files in the solution explorer then click the show the upper menu button of the solution explorer called show all files ( just hove your mouse cursor over the button there and you'll see the names of the buttons)

Just for basic knowledge: If the file resides in a different project\ assembly then it has to be defined, otherwise it has to be define at least as internal or public. in case your class is inheriting from that class that it can be protected as well.

That's the problem. I've outputted a bunch of information (including the HTML to build the login page itself). So how do I redirect the user from one page to the next?

This means your application design is pretty broken. You shouldn't be doing output while your business logic is running. Go an use a template engine (like Smarty) or quickfix it by using output buffering).

Another option (not a good one though!) would be outputting JavaScript to redirect:

<script type="text/javascript">location.href = 'newurl';</script>

The signature:

bool operator<<(const obj&, const obj&);

Seems rather suspect, this does not fit the stream convention nor the bitwise convention so it looks like a case of operator overloading abuse, operator < should return bool but operator << should probably return something else.

If you meant so say:

ostream& operator<<(ostream&, const obj&); 

Then since you can't add functions to ostream by necessity the function must be a free function, whether it a friend or not depends on what it has to access (if it doesn't need to access private or protected members there's no need to make it friend).

You can use an external library to help you out.

Little addition to all these posts.

Sometimes you may want to declare a class and yet not know how to define all of the methods that belong to that class. For example, you may want to declare a class called Writer and include in it a member method called write(). However, you don't know how to code write() because it is different for each type of Writer devices. Of course, you plan to handle this by deriving subclass of Writer, such as Printer, Disk, Network and Console.

I had the same problem with a Gradle project with a test SourceSet with two resource directories.

This snippet comes from a main-module.gradle and adds a resource dir to the test SourceSet:

sourceSets {
    test {
        resources {
            srcDir('../other-module/src/test/resources')
        }
    }
}

Doing this I had two resource directories related to the test SourceSet of the project main-module:

../other-module/src/test/resources src/test/resources (relative to the main-module folder, automatically added by the java plugin)

I find out that if I had two files with the same name in both the source directories, something in the process resources stage went wrong. As result, no compilation started and for this reason no .class were copied in the bin directory, where JUnit was looking for the classes. The ClassNotFoundException disappeared just renaming one of the two files.

<button type="button" onClick="refreshPage()">Close</button>

In the beaten-up MVC pattern, the Servlet is "C" - controller.

Its main job is to do initial request evaluation and then dispatch the processing based on the initial evaluation to the specific worker. One of the worker's responsibilities may be to setup some presentation layer beans and forward the request to the JSP page to render HTML. So, for this reason alone, you need to pass the request object to the service layer.

I would not, though, start writing raw Servlet classes. The work they do is very predictable and boilerplate, something that framework does very well. Fortunately, there are many available, time-tested candidates ( in the alphabetical order ): Apache Wicket, Java Server Faces, Spring to name a few.

Use this instead

echo $LINE | sed -e 's/12345678/$replace/g'

this works for me just simply remove the quotes

All these solutions are absolutely horrid. Just convert your SVG to a PNG and use the vanilla <Image/> component. The fact that react-native still does not support SVG images in the Image component is a joke. You should never install an additional library for such a simple task. Use https://svgtopng.com/

If you want a cross-platform method of doing this, the general pattern is to derive from QThread and create a function (static, if you'd like) in your derived class that will call one of the sleep functions in QThread.

if( obj[0] )

a cleaner version of this might be:

if( typeof Object.keys(obj)[0] === 'undefined' )

where the result will be undefined if no object property is set.

You need pow(); function from math.h header.
syntax

#include <math.h>
double pow(double x, double y);
float powf(float x, float y);
long double powl(long double x, long double y);

Here x is base and y is exponent. result is x^y.

usage

pow(2,4);  

result is 2^4 = 16. //this is math notation only   
// In c ^ is a bitwise operator

And make sure you include math.h to avoid warning ("incompatible implicit declaration of built in function 'pow' ").

            else:

while count < int(numprimes):
    if primetest(potentialprime) == True:

        count += 1
        potentialprime += 1

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and
• the output of the java --version and java -fullversion commands will distinguish Oracle JDK builds from OpenJDK builds.

To unzip all files in a directory just type this cmd in terminal:

Here's a toy example in Python:

>>> from functools import partial as curry

>>> # Original function taking three parameters:
>>> def display_quote(who, subject, quote):
        print who, 'said regarding', subject + ':'
        print '"' + quote + '"'


>>> display_quote("hoohoo", "functional languages",
           "I like Erlang, not sure yet about Haskell.")
hoohoo said regarding functional languages:
"I like Erlang, not sure yet about Haskell."

>>> # Let's curry the function to get another that always quotes Alex...
>>> am_quote = curry(display_quote, "Alex Martelli")

>>> am_quote("currying", "As usual, wikipedia has a nice summary...")
Alex Martelli said regarding currying:
"As usual, wikipedia has a nice summary..."

(Just using concatenation via + to avoid distraction for non-Python programmers.)

Editing to add:

See http://docs.python.org/library/functools.html?highlight=partial#functools.partial, which also shows the partial object vs. function distinction in the way Python implements this.

It took me quite a while to figure out, how to not get a false when using openssl_decrypt() and get encrypt and decrypt working.

    // cryptographic key of a binary string 16 bytes long (because AES-128 has a key size of 16 bytes)
    $encryption_key = '58adf8c78efef9570c447295008e2e6e'; // example
    $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cbc'));
    $encrypted = openssl_encrypt($plaintext, 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, $iv);
    $encrypted = $encrypted . ':' . base64_encode($iv);

    // decrypt to get again $plaintext
    $parts = explode(':', $encrypted);
    $decrypted = openssl_decrypt($parts[0], 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, base64_decode($parts[1])); 

If you want to pass the encrypted string via a URL, you need to urlencode the string:

    $encrypted = urlencode($encrypted);

To better understand what is going on, read:

• http://blog.turret.io/the-missing-php-aes-encryption-example/
• http://thefsb.tumblr.com/post/110749271235/using-opensslendecrypt-in-php-

To generate 16 bytes long keys you can use:

    $bytes = openssl_random_pseudo_bytes(16);
    $hex = bin2hex($bytes);

To see error messages of openssl you can use: echo openssl_error_string();

Hope that helps.

Remove the coma at the end of your SELECT statement (VALUE,), and also remove the one at the end of your FROM statement (rrf b,)

Define set

a = set()

Use add to append single values

a.add(1)
a.add(2)

Use update to add elements from tuples, sets, lists or frozen-sets

a.update([3,4])

>> print(a)
{1, 2, 3, 4}

If you want to add a tuple or frozen-set itself, use add

a.add((5, 6))

>> print(a)
{1, 2, 3, 4, (5, 6)}

Note: Since set elements must be hashable, and lists are considered mutable, you cannot add a list to a set. You also cannot add other sets to a set. You can however, add the elements from lists and sets as demonstrated with the ".update" method.

I was stumped when this happened randomly for me for one of my containers, while the other containers were fine. The container was attached to at least one non-internal network, so there was nothing wrong with the Compose definition. Restarting the VM / docker daemon did not help. It was also not a DNS issue because the container could not even ping an external IP. What solved it for me was to recreate the docker network(s). In my case, docker-compose down && docker-compose up worked.

Compose

This forces the recreation of all networks of all the containers:

docker-compose down && docker-compose up

Swarm mode

I suppose you just remove and recreate the service, which recreates the service's network(s):

docker service rm some-service

docker service create ...

If the container's network(s) are external

Simply remove and recreate the external networks of that service:

docker network rm some-external-network

docker network create some-external-network

If nothing worked for you, make sure the file is not open in another program. I was trying to import an xlsx file and Excel was blocking me from doing so.

In IIS Manager, right click on the site and go to Manage Web Site -> Advanced Settings. Under Connection Limits option, you should see Connection Time-out.

For http connections, the WebRequest and WebResponse classes use SSL to communicate with web hosts that support SSL. The decision to use SSL is made by the WebRequest class, based on the URI it is given. If the URI begins with "https:", SSL is used; if the URI begins with "http:", an unencrypted connection is used.

First, follow the instructions in this question to squash everything to a single commit. Then make a forced push to the remote:

$ git push origin +master

And optionally delete all other branches both locally and remotely:

$ git push origin :<branch>
$ git branch -d <branch>

I had a similar issue in Mac where svn was picking mac login as user name and I was getting error as

svn: E170013: Unable to connect to a repository at URL 'https://repo:8443/svn/proj/trunk'
svn: E175013: Access to '/svn/proj/trunk' forbidden

I used the --username along with svn command to pass the correct username which helped me. Alternatively, you can delete ~/.subversion/auth file, after which svn will prompt you for username.

nullptr is always a pointer type. 0 (aka. C's NULL bridged over into C++) could cause ambiguity in overloaded function resolution, among other things:

f(int);
f(foo *);

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

Deleting and Recreating a project with same name is tricky. If you try to follow above suggested steps and try to create a project with same name as the one you just deleted, you will run into error like

'C:/xxxxxx/pom.xml' already exists in VFS

Here is what I found would work.

1. Remove module
2. File -> Invalidate Cache (at this point the Intelli IDEA wants to restart)
3. Close project
4. Delete the folder form system explorer.
5. Now you can create a project with same name as before.

Support, unfortunately, is brutal at best. Here's a post on the topic:

    echo $CMD

It also happened to me

I use this code and it worked

require('events').EventEmitter.defaultMaxListeners = infinity;

Try it out. It may help

Thanks

This should be more helpful for debug. Answer from @Juned Ahsan will not specify full URL and will not print multiple headers/parameters.

private String httpServletRequestToString(HttpServletRequest request) {
    StringBuilder sb = new StringBuilder();

    sb.append("Request Method = [" + request.getMethod() + "], ");
    sb.append("Request URL Path = [" + request.getRequestURL() + "], ");

    String headers =
        Collections.list(request.getHeaderNames()).stream()
            .map(headerName -> headerName + " : " + Collections.list(request.getHeaders(headerName)) )
            .collect(Collectors.joining(", "));

    if (headers.isEmpty()) {
        sb.append("Request headers: NONE,");
    } else {
        sb.append("Request headers: ["+headers+"],");
    }

    String parameters =
        Collections.list(request.getParameterNames()).stream()
            .map(p -> p + " : " + Arrays.asList( request.getParameterValues(p)) )
            .collect(Collectors.joining(", "));             

    if (parameters.isEmpty()) {
        sb.append("Request parameters: NONE.");
    } else {
        sb.append("Request parameters: [" + parameters + "].");
    }

    return sb.toString();
}

Even after trying suggested solution, it was not solving my problem because there where many instance of java path were entered by me.

1. I removed all java related path (different version java) from "Path, JAVA_HOME, JRE_HOME" and created from fresh.

2. i have set (path may changes as per different installation)
   a. JAVA_HOME as C:\Program Files\Java\jdk1.8.0_191
   b. JRE_HOME as C:\Program Files\Java\jdk1.8.0_191\jre\lib
   c. add binary file path in path: C:\Program Files\Java\jdk1.8.0_191\bin
   d. CLASSPATH as C:\apache-tomcat-7.0.93\lib

3. never try in the same command prompt if its already open while doing changes/creting system/user variables. close it and open new one.

You should try dplyr package

library(dplyr)
a <- data.frame(A = c(1, 2, 3, 4),
               B = c(11, 12, 13, 14))


system.time({
for (i in 50:1000) {
    b <- data.frame(A = i, B = i * i)
    a <- bind_rows(a, b)
}

})

Output

   user  system elapsed 
   0.25    0.00    0.25

In contrast with using rbind function

a <- data.frame(A = c(1, 2, 3, 4),
                B = c(11, 12, 13, 14))


system.time({
    for (i in 50:1000) {
        b <- data.frame(A = i, B = i * i)
        a <- rbind(a, b)
    }

})

Output

   user  system elapsed 
   0.49    0.00    0.49 

There is some performance gain.

This should work...

JavaScriptSerializer ser = new JavaScriptSerializer();
var records = new ser.Deserialize<List<Record>>(jsonData);

{
    public string Name;
    public int Age;
    public string Location;
}
public class Record
{
    public Person record;
}

I had the same problem, but in c# 2012 I closed the "report data" and I couldn't find it and I finally found a solution to this issue.

This is my method:

VIEW >> TOOLBARS >> CUSTOMIZE >> COMMANDS ... select from the "Menu bar" .. VIEW.

OK now in the "Controls" find the "REPORT DATA", select it and MOVE it UP, close the menu. After that select a file.rdlc and click on the "View" ... OK Finally will be appeared "REPORT DATA"...

Use the left function:

QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "

Also have a look at mid() if you want more control.

You can learn commands from the command palette Ctrl/Cmd + Shift + P). Look for "Go to Bracket". The keybinding is also shown there.

C# is a language, .NET is an application framework. The .NET libraries can run on the CLR and thus any language which can run on the CLR can also use the .NET libraries.

If you are familiar with Java, this is similar... Java is a language built on top of the JVM... though any of the pre-assembled Java libraries can be used by another language built on top of the JVM.

Python uses the :: to separate the End, the Start, and the Step value.

Just go to the project Properties->Project Facets

1. Uncheck the dynamic module, click apply.

2. Maven->update the project.

If you really need it...

html { overflow-y: hidden; }

In the simple case you can do:

var user = cnn.Query<User>("spGetUser", new {Id = 1}, 
        commandType: CommandType.StoredProcedure).First();

If you want something more fancy, you can do:

 var p = new DynamicParameters();
 p.Add("@a", 11);
 p.Add("@b", dbType: DbType.Int32, direction: ParameterDirection.Output);
 p.Add("@c", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);

 cnn.Execute("spMagicProc", p, commandType: CommandType.StoredProcedure); 

 int b = p.Get<int>("@b");
 int c = p.Get<int>("@c"); 

Additionally you can use exec in a batch, but that is more clunky.

Adding to Matt's answer above (as I don't have comment privileges yet), one mouse-free workflow would be:

Esc then m then Enter so that you gain focus again and can start typing.

Without the last Enter you would still be in Escape mode and would otherwise have to use your mouse to activate text input in the cell.

Another way would be to add a new cell, type out your markdown in "Code" mode and then change to markdown once you're done typing everything you need, thus obviating the need to refocus.

You can then move on to your next cells. :)

json_decode($json, true); 
// the second param being true will return associative array. This one is easy.

I developed a home brew GA for a 3D laser surface profile system my company developed for the freight industry back in 1992. The system relied upon 3 dimensional triangulation and used a custom laser line scanner, a 512x512 camera (with custom capture hw). The distance between the camera and laser was never going to be precise and the focal point of the cameras were not to be found in the 256,256 position that you expected it to be!

It was a nightmare to try and work out the calibration parameters using standard geometry and simulated annealing style equation solving.

The Genetic algorithm was whipped up in an evening and I created a calibration cube to test it on. I knew the cube dimensions to high accuracy and thus the idea was that my GA could evolve a set of custom triangulation parameters for each scanning unit that would overcome production variations.

The trick worked a treat. I was flabbergasted to say the least! Within around 10 generations my 'virtual' cube (generated from the raw scan and recreated from the calibration parameters) actually looked like a cube! After around 50 generations I had the calibration I needed.

http://jsfiddle.net/DqGB8/1/

This is my solution

var error=0;
var test = [" ", "   "];
 if(test[0].match(/^\s*$/g)) {
     $("#output").html("MATCH!");
     error+=1;
 } else {
     $("#output").html("no_match");
 }

In windows 10, just exit out of current login and run this on command line

I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

I'd recommend this article on CSS Tricks by Chris Coyier entitled Better Helvetica:

http://css-tricks.com/snippets/css/better-helvetica/

He basically recommends the following declaration for covering all the bases:

body {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
}

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

I noticed someone mentioned jQuery, but I didn't know there was an isArray() function. It turns out it was added in version 1.3.

jQuery implements it as Peter suggests:

isArray: function( obj ) {
    return toString.call(obj) === "[object Array]";
},

Having put a lot of faith in jQuery already (especially their techniques for cross-browser compatibility) I will either upgrade to version 1.3 and use their function (providing that upgrading doesn’t cause too many problems) or use this suggested method directly in my code.

Many thanks for the suggestions.

This works in my case. I hope you can extract meaning out of it.

//div[text()='building1' and @class='wrap']/ancestor::tr/td/div/div[@class='x-grid-row-checker']

From previous project experience, this is a good way:

In the constants.js:

// constants.js

'use strict';

let constants = {
    key1: "value1",
    key2: "value2",
    key3: {
        subkey1: "subvalue1",
        subkey2: "subvalue2"
    }
};

module.exports =
        Object.freeze(constants); // freeze prevents changes by users

In main.js (or app.js, etc.), use it as below:

// main.js

let constants = require('./constants');

console.log(constants.key1);

console.dir(constants.key3);

I had the same problem. Try this.

Since I18n is the Rails core feature starting from version 2.2 you can use its localize-method. By applying the forementioned strftime %-variables you can specify the desired format under config/locales/en.yml (or whatever language), in your case like this:

time:
  formats:
    default: '%FT%T'

Or if you want to use this kind of format in a few specific places you can refer it as a variable like this

time:
  formats:
    specific_format: '%FT%T'

After that you can use it in your views like this:

l(Mode.last.created_at, format: :specific_format)  

You are getting that error because an application with a package name same as your application already exists. If you are sure that you have not installed the same application before, change the package name and try.

Else wise, here is what you can do:

1. Uninstall the application from the device: Go to Settings -> Manage Applications and choose Uninstall OR
2. Uninstall the app using adb command line interface: type adb uninstall After you are done with this step, try installing the application again.

I don't have enough rep to put this under comments to the existing answers:

unescape is only deprecated for working with URIs (or any encoded utf-8) which is probably the case for most people's needs. encodeURIComponent converts a js string to escaped UTF-8 and decodeURIComponent only works on escaped UTF-8 bytes. It throws an error for something like decodeURIComponent('%a9'); // error because extended ascii isn't valid utf-8 (even though that's still a unicode value), whereas unescape('%a9'); // © So you need to know your data when using decodeURIComponent.

decodeURIComponent won't work on "%C2" or any lone byte over 0x7f because in utf-8 that indicates part of a surrogate. However decodeURIComponent("%C2%A9") //gives you © Unescape wouldn't work properly on that // © AND it wouldn't throw an error, so unescape can lead to buggy code if you don't know your data.

Check out SSMS Tool Pack. It works in Management Studio 2005 and 2008. There is an option to generate insert statements which I've found helpful moving small amounts of data from one system to another.

With this option you will have to script out the DDL separately.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

Check this out : readdir()

This bit of code should list all entries in a certain directory:

if ($handle = opendir('.')) {

    while (false !== ($entry = readdir($handle))) {

        if ($entry != "." && $entry != "..") {

            echo "$entry\n";
        }
    }

    closedir($handle);
}

Edit: miah's solution is much more elegant than mine, you should use his solution instead.

here a little script I wrote to convert ascii to hex. hope it helps:

echo '0x'"`echo 'ASCII INPUT GOES HERE' | hexdump -vC |  awk 'BEGIN {IFS="\t"} {$1=""; print }' | awk '{sub(/\|.*/,"")}1'  | tr -d '\n' | tr -d ' '`" | rev | cut -c 3- | rev

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

In Git 2.x:

• If you are located directly at the working directory, then git add -A and git add . work without the difference.

• If you are in any subdirectory of the working directory, git add -A will add all files from the entire working directory, and git add . will add files from your current directory.

And that's all.

Multiple commands can be put in parenthesis and spread over numerous lines; so something like echo hi && echo hello can be put like this:

( echo hi
  echo hello )

Also variables can help:

set AFILEPATH="C:\SOME\LONG\PATH\TO\A\FILE"
if exist %AFILEPATH% (
  start "" /b %AFILEPATH% -option C:\PATH\TO\SETTING...
) else (
...

Also I noticed with carets (^) that the if conditionals liked them to follow only if a space was present:

if exist ^

As apc mentioned that error occurs "when a 32bit dll calls a 64bit dll or vice versa". The problem is that if you have build using AnyCPU and are running on a 64bit environment then the application will run as 64bit. If rebuilding explicitly for 32 and 64 bit is not an option then you could use a microsoft utility called corflags.exe which comes with the Windows SDK. Basically, you can modify a flag in the exe of the program you are executing to tell it to run as 32bit even if the environment is 64bit.

See here for information on using it

 public static void setCameraDisplayOrientation(Activity activity,
                                                   int cameraId, android.hardware.Camera camera) {
        android.hardware.Camera.CameraInfo info =
                new android.hardware.Camera.CameraInfo();
        android.hardware.Camera.getCameraInfo(cameraId, info);
        int rotation = activity.getWindowManager().getDefaultDisplay()
                .getRotation();
        int degrees = 0;
        switch (rotation) {
            case Surface.ROTATION_0: degrees = 0; break;
            case Surface.ROTATION_90: degrees = 90; break;
            case Surface.ROTATION_180: degrees = 180; break;
            case Surface.ROTATION_270: degrees = 270; break;
        }

        int result;
        if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            result = (info.orientation + degrees) % 360;
            result = (360 - result) % 360;  // compensate the mirror
        } else {  // back-facing
            result = (info.orientation - degrees + 360) % 360;
        }
        camera.setDisplayOrientation(result);
    }

You can use Modernizr JS (see also this StackOverflow answer), or make a custom JS function:

function is_touch_device() {
 return 'ontouchstart' in window        // works on most browsers 
  || navigator.maxTouchPoints;       // works on IE10/11 and Surface
};

if ( is_touch_device() ) {
  $('html').addClass('touch');
} else {
  $('html').addClass('no-touch');
} 

to detect the support of touch event in the browser, and then assign a regular CSS property, traversing the element with the html.no-touch class, like this:

html.touch a {
    width: 480px;
}

/* FOR THE DESKTOP, SET THE HOVER STATE */
html.no-touch a:hover {
   width: auto;
   color:blue;
   border-color:green;
}

For Swift you can override the main.swift file and set the UserDefaults string there before you app runs. This way you do not have to restart the App to see the desired effect.

import Foundation
import UIKit

// Your initialisation code here
let langCultureCode: String = "LANGUAGE_CODE"

UserDefaults.standard.set([langCultureCode], forKey: "AppleLanguages")
UserDefaults.standard.synchronize()

UIApplicationMain(CommandLine.argc, CommandLine.unsafeArgv, nil, NSStringFromClass(AppDelegate.self))

paired together with the removal of @UIApplicationMain in your AppDelegate.swift file.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.
