To add bold, italic and underline, just add the following to the font argument:

font=("Arial", 8, 'normal', 'bold', 'italic', 'underline')

I think you've actually got a wider confusion here.

The initial error is that you're trying to call split on the whole list of lines, and you can't split a list of strings, only a string. So, you need to split each line, not the whole thing.

And then you're doing for points in Type, and expecting each such points to give you a new x and y. But that isn't going to happen. Types is just two values, x and y, so first points will be x, and then points will be y, and then you'll be done. So, again, you need to loop over each line and get the x and y values from each line, not loop over a single Types from a single line.

So, everything has to go inside a loop over every line in the file, and do the split into x and y once for each line. Like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")

    for line in readfile:
        Type = line.split(",")
        x = Type[1]
        y = Type[2]
        print(x,y)

getQuakeData()

As a side note, you really should close the file, ideally with a with statement, but I'll get to that at the end.

Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = readfile.readlines()
    Types = [line.split(",") for line in readlines]
    xs = [Type[1] for Type in Types]
    ys = [Type[2] for Type in Types]
    for x, y in zip(xs, ys):
        print(x,y)

getQuakeData()

Or, a better way to write that might be:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    # Use with to make sure the file gets closed
    with open(filename, "r") as readfile:
        # no need for readlines; the file is already an iterable of lines
        # also, using generator expressions means no extra copies
        types = (line.split(",") for line in readfile)
        # iterate tuples, instead of two separate iterables, so no need for zip
        xys = ((type[1], type[2]) for type in types)
        for x, y in xys:
            print(x,y)

getQuakeData()

Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.

We recently encountered this error, root cause turned out to be an expired SSL cert on the IIS server. The Load Balancer (infront of our web tier) found the SSL expired, and instead of handling the HTTP traffic over to one of the IIS servers, started showing this error. So basically IIS unable to server requests, for a totally different reason :)

I suddenly got an error like in any directory I tried to run any git command from:

fatal: Not a git repository: /Users/me/Desktop/../../.git/modules/some-submodule

For me, turned out I had a hidden file .git on my Desktop with the content:

gitdir: ../../.git/modules/some-module

Removed that file and fixed.

You can combine your counts like you were doing before, but then you could sum them all up a number of ways, one of which is shown below:

SELECT SUM(A) 
FROM
(
    SELECT 1 AS A
    UNION ALL 
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
) AS B

**The best is to use try except block to get rid of EOF **

try:
    width = input()
    height = input()
    def rectanglePerimeter(width, height):
       return ((width + height)*2)
    print(rectanglePerimeter(width, height))
except EOFError as e:
    print(end="")

Unexpected T_LNUMBER

The token T_LNUMBER refers to a "long" / number.

1. Invalid variable names

   In PHP, and most other programming languages, variables cannot start with a number. The first character must be alphabetic or an underscore.

   $1   // Bad
   $_1  // Good
   

   

   • Quite often comes up for using preg_replace-placeholders "$1" in PHP context:

     #                         ?            ?  ?
     preg_replace("/#(\w+)/e",  strtopupper($1) )
     

     Where the callback should have been quoted. (Now the /e regex flag has been deprecated. But it's sometimes still misused in preg_replace_callback functions.)

   • The same identifier constraint applies to object properties, btw.

            ?
     $json->0->value
     

   • While the tokenizer/parser does not allow a literal $1 as variable name, one could use ${1} or ${"1"}. Which is a syntactic workaround for non-standard identifiers. (It's best to think of it as a local scope lookup. But generally: prefer plain arrays for such cases!)

   • Amusingly, but very much not recommended, PHPs parser allows Unicode-identifiers; such that $? would be valid. (Unlike a literal 1).

2. Stray array entry

   An unexpected long can also occur for array declarations - when missing , commas:

   #            ? ?
   $xy = array(1 2 3);
   

   Or likewise function calls and declarations, and other constructs:

   • func(1, 2 3);
   • function xy($z 2);
   • for ($i=2 3<$z)
     
     

   So usually there's one of ; or , missing for separating lists or expressions.

3. Misquoted HTML

   And again, misquoted strings are a frequent source of stray numbers:

   #                 ? ?          
   echo "<td colspan="3">something bad</td>";
   

   Such cases should be treated more or less like Unexpected T_STRING errors.

4. Other identifiers

   Neither functions, classes, nor namespaces can be named beginning with a number either:

            ?
   function 123shop() {
   

   Pretty much the same as for variable names.

This is a function snippet I wrote to scan the user input for a string and then store that string on an array of the same size as the user input. Note that I initialize j to the value of 2 to be able to store the '\0' character.

char* dynamicstring() {
    char *str = NULL;
    int i = 0, j = 2, c;
    str = (char*)malloc(sizeof(char));
    //error checking
    if (str == NULL) {
        printf("Error allocating memory\n");
        exit(EXIT_FAILURE);
    }

    while((c = getc(stdin)) && c != '\n')
    {
        str[i] = c;
        str = realloc(str,j*sizeof(char));
        //error checking
        if (str == NULL) {
            printf("Error allocating memory\n");
            free(str);
            exit(EXIT_FAILURE);
        }

        i++;
        j++;
    }
    str[i] = '\0';
    return str;
}

In main(), you can declare another char* variable to store the return value of dynamicstring() and then free that char* variable when you're done using it.

After PHP 5 you can use this: echo date("c"); form ISO 8601 formatted datetime.

http://ideone.com/nD7piL

Note for comments:

Regarding to this, both of these expressions are valid for timezone, for basic format: ±[hh]:[mm], ±[hh][mm], or ±[hh].

But note that, +0X:00 is correct, and +0X00 is incorrect for extended usage. So it's better to use date("c"). A similar discussion here.

Simple answer: You should use RecyclerView in a situation where you want to show a lot of items, and the number of them is dynamic. ListView should only be used when the number of items is always the same and is limited to the screen size.

You find it harder because you are thinking just with the Android library in mind.

Today there exists a lot of options that help you build your own adapters, making it easy to build lists and grids of dynamic items that you can pick, reorder, use animation, dividers, add footers, headers, etc, etc.

Don't get scared and give a try to RecyclerView, you can starting to love it making a list of 100 items downloaded from the web (like facebook news) in a ListView and a RecyclerView, you will see the difference in the UX (user experience) when you try to scroll, probably the test app will stop before you can even do it.

I recommend you to check this two libraries for making easy adapters:

FastAdapter by mikepenz

FlexibleAdapter by davideas

Short answer: You can't. rm removes files blindly, with no concept of 'trash'.

Some Unix and Linux systems try to limit its destructive ability by aliasing it to rm -i by default, but not all do.

Long answer: Depending on your filesystem, disk activity, and how long ago the deletion occured, you may be able to recover some or all of what you deleted. If you're using an EXT3 or EXT4 formatted drive, you can check out extundelete.

In the future, use rm with caution. Either create a del alias that provides interactivity, or use a file manager.

You could decompose the date into it's constituent parts and then concatenate them together like this:

MsgBox(Now.Day & "/" & Now.Month & "/" & Now.Year)

• Some daemons (e.g. apache) do this by themselves by calling setuid()
• You could use the setuid-file flag to run the process as a different user.
• Of course, the solution you mentioned works as well.

If you intend to write your own daemon, then I recommend calling setuid(). This way, your process can

1. Make use of its root privileges (e.g. open log files, create pid files).
2. Drop its root privileges at a certain point during startup.

This is probably the easiest way, not the prettiest though:

SELECT *,
    (SELECT Count(*) FROM eventsTable WHERE columnName = 'Business') as RowCount
    FROM eventsTable
    WHERE columnName = 'Business'

This will also work without having to use a group by

SELECT *, COUNT(*) OVER () as RowCount
    FROM eventsTables
    WHERE columnName = 'Business'

There is an official Microsoft answer to this question at the following knowledge base article:

Article ID: 318785 - Last Review: November 7, 2008 - Revision: 20.1 How to determine which versions of the .NET Framework are installed and whether service packs have been applied

Unfortunately, it doesn't appear to work, because the mscorlib.dll version in the 2.0 directory has a 2.0 version, and there is no mscorlib.dll version in either the 3.0 or 3.5 directories even though 3.5 SP1 is installed ... why would the official Microsoft answer be so misinformed?

If you want to concatenate a variable with a fixed path and a string as the dynamic path into a whole path to remove the folder, you may need the following command:

$fixPath = "C:\Users\myUserName\Desktop"
Remove-Item ("$fixPath" + "\Folder\SubFolder") -Recurse

In the variable $newPath the concatenate path is now: "C:\Users\myUserName\Desktop\Folder\SubFolder"

So you can remove several directories from the starting point ("C:\Users\myUserName\Desktop"), which is already defined and fixed in the variable $fixPath.

$fixPath = "C:\Users\myUserName\Desktop"
Remote-Item ("$fixPath" + "\Folder\SubFolder") -Recurse
Remote-Item ("$fixPath" + "\Folder\SubFolder1") -Recurse
Remote-Item ("$fixPath" + "\Folder\SubFolder2") -Recurse

See this fiddle for a preview and check the documentation for jquerys toggle and animate methods.

$('#toggle').toggle(function(){
    $('#A').animate({width:0});
    $('#B').animate({left:0});
},function(){
    $('#A').animate({width:200});
    $('#B').animate({left:200});
});

Basically you animate on the properties that sets the layout.

A more advanced version:

$('#toggle').toggle(function(){
    $('#A').stop(true).animate({width:0});
    $('#B').stop(true).animate({left:0});
},function(){
    $('#A').stop(true).animate({width:200});
    $('#B').stop(true).animate({left:200});
})

This stops the previous animation, clears animation queue and begins the new animation.

I provided the configuration values to word hosted .nET Compoent as follows.

A .NET Class Library component being called/hosted in MS Word. To provide configuration values to my component, I created winword.exe.config in C:\Program Files\Microsoft Office\OFFICE11 folder. You should be able to read configurations values like You do in Traditional .NET.

string sMsg = System.Configuration.ConfigurationManager.AppSettings["WSURL"];

++x is called preincrement while x++ is called postincrement.

int x = 5, y = 5;

System.out.println(++x); // outputs 6
System.out.println(x); // outputs 6

System.out.println(y++); // outputs 5
System.out.println(y); // outputs 6

you can do this in different ways:

1. Setting a timeout in the web service caller from code (not 100% sure but I think I have seen this done);
2. Setting a timeout in the constructor of the web service proxy in the web references;
3. Setting a timeout in the server side, web.config of the web service application.

see here for more details on the second case:

http://msdn.microsoft.com/en-us/library/ff647786.aspx#scalenetchapt10_topic14

and here for details on the last case:

How to increase the timeout to a web service request?

I managed to fix it :D heres the code.

var divh = document.getElementById('first').offsetHeight;
$("#first").css('height', '100px');
$("div:first").click(function() {
  $("#first").animate({
    height: divh
  }, 1000);
});

Yes, you need to negate File.Exists(path) if you want to check if the file doesn't exist.

It's definitely an issue with some of the projects being built for x86 compatibility instead of any CPU. If I had to guess I would say that some of the references between your projects are probably referencing the dll's in some of the bin\debug folders instead of being project references.

When a project is compiled for x86 instead of 'Any CPU' the dll's go into the bin\x86\debug folder instead of bin\debug (which is probably where your references are looking).

But in any case, you should be using project references between your projects.

In java you can use setFetchSource like this :

client.prepareSearch(index).setTypes(type)
            .setFetchSource(new String[] { "field1", "field2" }, null)

First and last day of the current month:

select dateadd(mm, -1,dateadd(dd, +1, eomonth(getdate()))) as FirstDay, 
eomonth(getdate()) as LastDay

Try this

var selectedDueDateField = document.getElementById("selectedDueDate");
var element = angular.element(selectedDueDateField);
element.val('new value here');
element.triggerHandler('input');

This may be the best way for the email validation for your textbox.

string pattern = null;
pattern = "^([0-9a-zA-Z]([-\\.\\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\\w]*[0-9a-zA-Z]\\.)+[a-zA-Z]{2,9})$";

if (Regex.IsMatch("txtemail.Text", pattern))
{
MessageBox.Show ("Valid Email address ");
}
else
{
MessageBox.Show("Invalid Email Email");
}

Just include in any function where you want.

Another solution might look like this,

char arr[] = "mom";
std::cout << "hi " << std::string(arr);

which avoids using an extra variable.

Just add click event by jquery in $(document).ready() like :

$(document).ready(function(){

                  $('#YourControlID').click(function(){
                     if(Check your condtion)
                     {
                             $.messager.show({  
                                title:'My Title',  
                                msg:'The message content',  
                                showType:'fade',  
                                style:{  
                                    right:'',  
                                    bottom:''  
                                }  
                            });  
                     }
                 });
            });

You can also define an environment variable that is visible only within Eclipse.

Go to Run -> Run Configurations... and Select tab "Environment".

There you can add several environment variables that will be specific to your application.

You need to specify workseet. Change line

If Worksheet.Cells(i, 1).Value = "X" Then

to

If Worksheets("Sheet2").Cells(i, 1).Value = "X" Then

UPD:

Try to use following code (but it's not the best approach. As @SiddharthRout suggested, consider about using Autofilter):

Sub LastRowInOneColumn()
   Dim LastRow As Long
   Dim i As Long, j As Long

   'Find the last used row in a Column: column A in this example
   With Worksheets("Sheet2")
      LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
   End With

   MsgBox (LastRow)
   'first row number where you need to paste values in Sheet1'
   With Worksheets("Sheet1")
      j = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
   End With 

   For i = 1 To LastRow
       With Worksheets("Sheet2")
           If .Cells(i, 1).Value = "X" Then
               .Rows(i).Copy Destination:=Worksheets("Sheet1").Range("A" & j)
               j = j + 1
           End If
       End With
   Next i
End Sub

There is also a sample on the MSDN Code Samples gallery called Converting between RTF and HTML which allows you to convert between HTML, RTF and XAML.

If you don't need to initiate a post back when you press this button, then making the overhead of a server control isn't necesary.

<input id="addButton" type="button" value="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#addButton').click(function() 
         { 
             showDialog('#addPerson'); 
         });
     });
</script>

If you still need to be able to do a post back, you can conditionally stop the rest of the button actions with a little different code:

<asp:Button ID="buttonAdd" runat="server" Text="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#<%= buttonAdd.ClientID %>').click(function(e) 
         { 
             showDialog('#addPerson');

             if(/*Some Condition Is Not Met*/) 
                return false;
         });
     });
</script>

$id = 101;

$sql = 'SELECT * FROM ur_tbl t WHERE t.email_id = '. $id;
$email = Yii::app()->db->createCommand($sql)->queryAll();

var_dump($email);

There is a known bug in jQuery 1.6.2 that is triggered by a background image being placed on the body element.

The bug report and patch are:

http://bugs.jquery.com/ticket/9823

https://github.com/jquery/jquery/commit/5c4a9cc001fcd803efa65ff95571c72cbdafbe69

I've also had modernizr trigger this error but since I could work around it I never chased it down.

For anyone who is aware of the risks this implementation imposes, to have the password sync to your ViewModel simply add Mode=OneWayToSource.

XAML

<PasswordBox
    ff:PasswordHelper.Attach="True"
    ff:PasswordHelper.Password="{Binding Path=Password, Mode=OneWayToSource}" />

If you're using jQuery 1.5, then statusCode will work.

If you're using jQuery 1.4, try this:

error: function(jqXHR, textStatus, errorThrown) {
    alert(jqXHR.status);
    alert(textStatus);
    alert(errorThrown);
}

You should see the status code from the first alert.

I don't know about underline, but for bold and italic there is "bolditalic". There is no mention of underline here: http://developer.android.com/reference/android/widget/TextView.html#attr_android:textStyle

Mind you that to use the mentioned bolditalic you need to, and I quote from that page

Must be one or more (separated by '|') of the following constant values.

so you'd use bold|italic

You could check this question for underline: Can I underline text in an android layout?

You can change the size of the plot by adding this before you create the figure.

plt.rcParams["figure.figsize"] = [16,9]

Here's the formula used by Android:

px = dp * (dpi / 160)

Where dpi is one of the following screen densities. For a list of all possible densities go here

It defines the "DENSITY_*" constants.

• ldpi (low) ~120dpi
• mdpi (medium) ~160dpi
• hdpi (high) ~240dpi
• xhdpi (extra-high) ~320dpi
• xxhdpi (extra-extra-high) ~480dpi
• xxxhdpi (extra-extra-extra-high) ~640dpi

Taken from here.

This will sort out a lot of the confusion when translating between px and dp, if you know your screen dpi.

So, let's say you want an image of 60 dp for an hdpi screen then the physical pixel size of 60 dp is:

px = 60 * (240 / 160)

Here's another typical way:

$array = for($i = 0; $i -le 4; $i++) { $false }

import string
wrd=raw_input("Enter word").lower()
fwrd=""
for let in wrd:
    fwrd+=string.ascii_lowercase[(string.ascii_lowercase).index(let)+3]
print"Original word",wrd
print"New word",fwrd

No. You have to make your own like this:

boolean tryParseInt(String value) {  
     try {  
         Integer.parseInt(value);  
         return true;  
      } catch (NumberFormatException e) {  
         return false;  
      }  
}

...and you can use it like this:

if (tryParseInt(input)) {  
   Integer.parseInt(input);  // We now know that it's safe to parse
}

EDIT (Based on the comment by @Erk)

Something like follows should be better

public int tryParse(String value, int defaultVal) {
    try {
        return Integer.parseInt(value);
    } catch (NumberFormatException e) {
        return defaultVal;
    }
}

When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.

public int tryParse(String value) {
    return tryParse(value, 0)
}

I was looking for a simple package that would do this very same task and did not find anything so I created https://github.com/gregnb/react-to-print

You can use it like so:

 <ReactToPrint
   trigger={() => <a href="#">Print this out!</a>}
   content={() => this.componentRef}
 />
 <ComponentToPrint ref={el => (this.componentRef = el)} />

There can't be aggregate functions (Ex. COUNT, MAX, etc.) in A WHERE clause. Hence we use the HAVING clause instead. Therefore the whole query would be similar to this:

SELECT column_name, aggregate_function(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name
HAVING aggregate_function(column_name) operator value;

With Winforms you can use Form.BackColor to do this.
From within the Form's code:

BackColor = Color.LightPink;

If you mean a WPF Window you can use the Background property.
From within the Window's code:

Background = Brushes.LightPink;

Yes:

RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); 
params.addRule(RelativeLayout.BELOW, R.id.below_id);
viewToLayout.setLayoutParams(params);

First, the code creates a new layout params by specifying the height and width. The addRule method adds the equivalent of the xml properly android:layout_below. Then you just call View#setLayoutParams on the view you want to have those params.

I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this:

element.addEventListener("keydown", function(e){ console.log(e.key, e.char, e.keyCode) })

var e = new KeyboardEvent("keydown", {bubbles : true, cancelable : true, key : "Q", char : "Q", shiftKey : true});
element.dispatchEvent(e);

//If you need legacy property "keyCode"
// Note: In some browsers you can't overwrite "keyCode" property. (At least in Safari)
delete e.keyCode;
Object.defineProperty(e, "keyCode", {"value" : 666})

UPDATE:

Now my polyfill supports legacy properties "keyCode", "charCode" and "which"

var e = new KeyboardEvent("keydown", {
    bubbles : true,
    cancelable : true,
    char : "Q",
    key : "q",
    shiftKey : true,
    keyCode : 81
});

Examples here

Additionally here is cross-browser initKeyboardEvent separately from my polyfill: (gist)

Try to give permission to full control the python folder.

Find the python root directory-->right button click-->properties-->security-->edit-->give users Full Control-->yes and wait the process finished.

It works for me.

boolean

Boolean
Can be a Boolean object representing true or false, or can be null.
Default value is null.

Given you start with mapping.get("servers").getAsJsonArray(), if you have access to Guava Streams, you can do the below one-liner:

List<String> servers = Streams.stream(jsonArray.iterator())
                              .map(je -> je.getAsString())
                              .collect(Collectors.toList());

Note StreamSupport won't be able to work on JsonElement type, so it is insufficient.

In code to load resource in the executing assembly where my image 'Freq.png' was in the folder "Icons" and defined as "Resource".

        this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/" 
             + Assembly.GetExecutingAssembly().GetName().Name 
             + ";component/" 
             + "Icons/Freq.png", UriKind.Absolute)); 

I also made a function if anybody would like it...

/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
    if (assembly == null)
    {
        assembly = Assembly.GetCallingAssembly();
    }

    if (pathInApplication[0] == '/')
    {
        pathInApplication = pathInApplication.Substring(1);
    }
    return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute)); 
}

Usage:

        this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");

By default any files you add to src/main/resources will be included in the jar.

If you need to change that behavior for whatever reason, you can do so by configuring sourceSets.

This part of the documentation has all the details

These are compact methods to encrypt / decrypt strings with PHP using AES256 CBC:

function encryptString($plaintext, $password, $encoding = null) {
    $iv = openssl_random_pseudo_bytes(16);
    $ciphertext = openssl_encrypt($plaintext, "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, $iv);
    $hmac = hash_hmac('sha256', $ciphertext.$iv, hash('sha256', $password, true), true);
    return $encoding == "hex" ? bin2hex($iv.$hmac.$ciphertext) : ($encoding == "base64" ? base64_encode($iv.$hmac.$ciphertext) : $iv.$hmac.$ciphertext);
}

function decryptString($ciphertext, $password, $encoding = null) {
    $ciphertext = $encoding == "hex" ? hex2bin($ciphertext) : ($encoding == "base64" ? base64_decode($ciphertext) : $ciphertext);
    if (!hash_equals(hash_hmac('sha256', substr($ciphertext, 48).substr($ciphertext, 0, 16), hash('sha256', $password, true), true), substr($ciphertext, 16, 32))) return null;
    return openssl_decrypt(substr($ciphertext, 48), "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, substr($ciphertext, 0, 16));
}

Usage:

$enc = encryptString("mysecretText", "myPassword");
$dec = decryptString($enc, "myPassword");

You usually use padding to add distance between a border and a content.However, background are spread on padding.

You can still do it with nested element.

html :

<div id="outter">
    <div id="inner">
        test
    </div>
</div>

outter div :

border-style: ridge;
border-color: #567498;
border-spacing:10px;
min-width: 100px;
min-height: 100px;
float:left;

inner div :

width: 100px;
min-height: 100px;
margin: 10px;
background-image: -webkit-gradient(
    linear,
    left bottom,
    left top,
    color-stop(0, rgb(39,54,73)),
    color-stop(1, rgb(30,42,54))
);
background-image: -moz-linear-gradient(
    center bottom,
    rgb(39,54,73) 0%,
    rgb(30,42,54) 100%
        );}

The lookup module of ansible works fine for me. The yml is:

- hosts: test
  vars:
    time: "{{ lookup('pipe', 'date -d \"1 day ago\" +\"%Y%m%d\"') }}"

You can replace any command with date to get result of the command.

DTO classes are used to serialize/deserialize data from different sources. When you want to deserialize a object from a source, does not matter what external source it is: service, file, database etc. you may be only want to use some part of that but you want an easy way to deserialize that data to an object. after that you copy that data to the XModel you want to use. A serializer is a beautiful technology to load DTO objects. Why? you only need one function to load (deserialize) the object.

Have a look at the handleEvent method
https://developer.mozilla.org/en-US/docs/Web/API/EventListener

"Raw" Javascript:

function MyObj() {
   this.abc = "ABC";
}
MyObj.prototype.handleEvent = function(e) {
   console.log("caught event: "+e.type);
   console.log(this.abc);
}

var myObj = new MyObj();

document.querySelector("#myElement").addEventListener('click', myObj);

Now click on your element (with id "myElement") and it should print the following in the console:

caught event: click
ABC

This allows you to have an object method as event handler, and have access to all the object properties in that method.

You can't just pass a method of an object to addEventListener directly (like that: element.addEventListener('click',myObj.myMethod);) and expect myMethod to act as if I was normally called on the object. I am guessing that any function passed to addEventListener is somehow copied instead of being referenced. For example, if you pass an event listener function reference to addEventListener (in the form of a variable) then unset this reference, the event listener is still executed when events are caught.

Another (less elegant) workaround to pass a method as event listener and stil this and still have access to object properties within the event listener would be something like that:

// see above for definition of MyObj

var myObj = new MyObj();

document.querySelector("#myElement").addEventListener('click', myObj.handleEvent.bind(myObj));

In HTML

<div style="overflow: hidden;">

in CSS

overflow: hidden;

you can also end scrolling for x or y separately

overflow-y: hidden; /* Hide vertical scrollbar */
  overflow-x: hidden; /* Hide horizontal scrollbar */

There is a Yahoo YUI component (Browser History Manager) which can handle this: http://developer.yahoo.com/yui/history/

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

[amazonec2]
nginx.log.directory = /var/log/nginx
nginx.root.directory = /usr/share/nginx
nginx.conf.directory = /etc/nginx
nginx.run.directory  = /var/run
nginx.user           = nginx

[macports]
nginx.log.directory = /opt/local/var/log/nginx
nginx.root.directory = /opt/local/share/nginx
nginx.conf.directory = /opt/local/etc/nginx
nginx.run.directory  = /opt/local/var/run
nginx.user           = _www

One script to rule them all: this combines truncate and delete commands with sp_MSforeachtable so that you can avoid dropping and recreating constraints - just specify the tables that need to be deleted rather than truncated and for my purposes I have included an extra schema filter for good measure (tested in 2008r2)

declare @schema nvarchar(max) = 'and Schema_Id=Schema_id(''Value'')'
declare @deletiontables nvarchar(max) = '(''TableA'',''TableB'')'
declare @truncateclause nvarchar(max) = @schema + ' and o.Name not in ' +  + @deletiontables;
declare @deleteclause nvarchar(max) = @schema + ' and o.Name in ' + @deletiontables;        

exec sp_MSforeachtable 'alter table ? nocheck constraint all', @whereand=@schema
exec sp_MSforeachtable 'truncate table ?', @whereand=@truncateclause
exec sp_MSforeachtable 'delete from ?', @whereand=@deleteclause
exec sp_MSforeachtable 'alter table ? with check check constraint all', @whereand=@schema

I use Universal Image loader library to download and round the corners of image, and it worked for me.

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(thisContext)
            // You can pass your own memory cache implementation
           .discCacheFileNameGenerator(new HashCodeFileNameGenerator())
           .build();

DisplayImageOptions options = new DisplayImageOptions.Builder()
            .displayer(new RoundedBitmapDisplayer(10)) //rounded corner bitmap
            .cacheInMemory(true)
            .cacheOnDisc(true)
            .build();

ImageLoader imageLoader = ImageLoader.getInstance();
imageLoader.init(config);
imageLoader.displayImage(image_url,image_view, options );

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:

CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();

it should be slightly faster since it doesn't need to parse an input format.

I believe you want bgcolor. Something like this:

document.getElementById("button").bgcolor="#ffffff";

Here are a couple of demos that might help:

Background Color

Background Color Changer

To a kill a specific port in Linux use below command

sudo fuser -k Port_Number/tcp

replace Port_Number with your occupied port.

You have checked that R is actually able to find the file, e.g. file.exists("C:/AB_DNA_Tag_Numbers.xlsx") ? – Ben Bolker Aug 14 '11 at 23:05

Above comment should've solved your problem:

require("xlsx")
read.xlsx("filepath/filename.xlsx",1) 

should work fine after that.

I had a similar requirement, but I wanted the n'th item in a particular group. This is how I solved it.

groups = data.groupby(['group_key'])
selection = groups['index_col'].apply(lambda x: x % 3 == 0)
subset = data[selection]

Xcode 11.2.1, December 2019

Apple gives you crash log in .txt format , which is unsymbolicated

**

With the device connected

**

• Download ".txt" file , change extension to ".crash"
  • Open devices and simulators from window tab in Xcode
  • select device and select device logs
  • drag and drop .crash file to the device log window

We will be able to see symbolicated crash logs over there

Please see the link for more details on Symbolicating Crash logs

You might want to look into a Python package manager like pip. If you don't want to use a Python package manager, you should be able to download M2Crypto and build/compile/install over the old installation.

System.Diagnostics.Process.Start("Exe Name");

Download the latest gradle from https://gradle.org/install and set the gradle path upto bin in your PATH variable and export path in the directory you are working in

example : export PATH=/home/abc/android-sdk-linux/tools:/home/abc/android-sdk-linux/platform-tools:/home/abc/android-sdk-linux/tools:/home/abc/android-sdk-linux/platform-tools:/home/abc/Downloads/gradle-4.4.1/bin

I spent my whole day resolve this and ultimately this solution worked for me,

Since Java 8, there are some standard options to do this in JDK:

Collection<E> in = ...
Object[] mapped = in.stream().map(e -> doMap(e)).toArray();
// or
List<E> mapped = in.stream().map(e -> doMap(e)).collect(Collectors.toList());

See java.util.Collection.stream() and java.util.stream.Collectors.toList().

1. It's good practice to give a parent to your QTimer to use Qt's memory management system.

2. update() is a QWidget function - is that what you are trying to call or not? http://qt-project.org/doc/qt-4.8/qwidget.html#update.

3. If number 2 does not apply, make sure that the function you are trying to trigger is declared as a slot in the header.

4. Finally if none of these are your issue, it would be helpful to know if you are getting any run-time connect errors.

If you want to delete right now, use unmanaged memory.

See:

• Marshal.AllocHGlobal
• Marshal.FreeHGlobal
• Marshal.DestroyStructure

The easiest way to do this would be to use a filter.

You can either filter for any cells in column A that don't have a "-" and copy / paste, or (my more preferred method) filter for all cells that do have a "-" and then select all and delete - Once you remove the filter, you're left with what you need.

Hope this helps.

Another simple way would be using a root explorer app on your phone.

Then go to /data/data/package name/shared preferences folder/name of your preferences.xml, you can use ES File explorer, and go to the root of your device, not sd card.

I had to rewrite BufferedReader to avoid synchronized and a couple of boundary conditions that is not needed.(Atleast that's what I felt.It is not unit tested so use it at your own risk.)

/**
 * Reads text from a character-input stream, buffering characters so as to
 * provide for the efficient reading of characters, arrays, and lines.
 * <p>
 * <p> The buffer size may be specified, or the default size may be used.  The
 * default is large enough for most purposes.
 * <p>
 * <p> In general, each read request made of a Reader causes a corresponding
 * read request to be made of the underlying character or byte stream.  It is
 * therefore advisable to wrap a CustomBufferedReader around any Reader whose read()
 * operations may be costly, such as FileReaders and InputStreamReaders.  For
 * example,
 * <p>
 * <pre>
 * CustomBufferedReader in
 *   = new CustomBufferedReader(new FileReader("foo.in"));
 * </pre>
 * <p>
 * will buffer the input from the specified file.  Without buffering, each
 * invocation of read() or readLine() could cause bytes to be read from the
 * file, converted into characters, and then returned, which can be very
 * inefficient.
 * <p>
 * <p> Programs that use DataInputStreams for textual input can be localized by
 * replacing each DataInputStream with an appropriate CustomBufferedReader.

Bottomline not much difference between BufferedReader and my CustomReader and it is very miniscule and hence you can use this to read your file.

Trust me you don't have to break your head.use BufferedReader with readLine,it is properly tested.At worst if you feel you can improve it just override and change it to StringBuilder instead of StringBuffer just to shave off half a second

Me, I'd do it something like this:

HTML:

onclick="myfunction({path:'/myController/myAction', ok:myfunctionOnOk, okArgs:['/myController2/myAction2','myParameter2'], cancel:myfunctionOnCancel, cancelArgs:['/myController3/myAction3','myParameter3']);"

JS:

function myfunction(params)
{
  var path = params.path;

  /* do stuff */

  // on ok condition 
  params.ok(params.okArgs);

  // on cancel condition
  params.cancel(params.cancelArgs);  
}

But then I'd also probable be binding a closure to a custom subscribed event. You need to add some detail to the question really, but being first-class functions are easily passable and getting params to them can be done any number of ways. I would avoid passing them as string labels though, the indirection is error prone.

align-self-start, align-self-center... in flexbox

ABCpdf will do this and many other things for you.

Not ony will it render your PDF to a variety of formats (eg JPEG, GIF, PNG, TIFF, JPEG 2000; vector EPS, SVG, Flash and PostScript) but it can also do so in a variety of color spaces (eg Gray, RGB, CMYK) and bit depths (eg 1, 8, 16 bits per component).

And that's just some of what it will do!

For more details see:

http://www.websupergoo.com/abcpdf-8.htm

Oh and you can get free licenses via the free license scheme.

There are EULA issues with using Acrobat to do PDF rendering. If you want to go down this route check the legalities very carefully first.

Its better if you use validation code to the users input for making it restricted to use symbols and part of code in your input form. If you embeed php in html code your php code have to become on the top to make sure that it is not ignored as comment if a hacker edit the page and add /* in your html code

You could simply use an empty View with a bottom border.

<View
  style={{
    borderBottomColor: 'black',
    borderBottomWidth: 1,
  }}
/>

visibility=hidden

is very useful, but it will still take up space on the page. You can also use

display=none

because that will not only hide the object, but make it so that it doesn't take up space until it is displayed. (Also keep in mind that display's opposite is "block," not "visible")

You can use SelectedValue:

<EditItemTemplate>
    <asp:DropDownList ID="ddlPBXTypeNS"
                      runat="server"
                      Width="200px"
                      DataSourceID="YDS"
                      DataTextField="CaptionValue"
                      DataValueField="OID"
                      SelectedValue='<%# Bind("YourForeignKey") %>' />
    <asp:YourDataSource ID="YDS" ...../>
</EditItemTemplate>

grantUriPermission (from Android document)

Normally you should use Intent#FLAG_GRANT_READ_URI_PERMISSION or Intent#FLAG_GRANT_WRITE_URI_PERMISSION with the Intent being used to start an activity instead of this function directly. If you use this function directly, you should be sure to call revokeUriPermission(Uri, int) when the target should no longer be allowed to access it.

So I test and I see that.

• If we use grantUriPermission before we start a new activity, we DON'T need FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION in Intent to overcome SecurityException

• If we don't use grantUriPermission. We need to use FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION to overcome SecurityException but

  • Your intent MUST contain Uri by setData or setDataAndType else SecurityException still throw. (one interesting I see: setData and setType can not work well together so if you need both Uri and type you need setDataAndType. You can check inside Intent code, currently when you setType, it will also set uri= null and when you setUri it will also set type=null)

On macOS 10.13.6 with MongoDB 4.0

I was unable to connect to localhost from the mongo shell

I started MongoDB with:

mongod --config /usr/local/etc/mongod.conf

I found that the 'mongod.conf' had:

bindIp: 127.0.0.1

Change my JavaScript connection from localhost to 127.0.0.1 and it worked fine.

The same was occurring with MongoDB Compass too.

I ended up adding the following to my build.gradle:

bootRun {
  environment SPRING_PROFILES_ACTIVE: environment.SPRING_PROFILES_ACTIVE ?: "local"
}

test {
  environment SPRING_PROFILES_ACTIVE: environment.SPRING_PROFILES_ACTIVE ?: "test"
}

So now when running bootRun from IntelliJ, it defaults to the "local" profile.

On our other environments, we will simply set the 'SPRING_PROFILES_ACTIVE' environment variable in Tomcat.

I got this from a comment found here: https://github.com/spring-projects/spring-boot/pull/592

I think this is what you are looking for: jquery-html5-placeholder-fix

This solution uses feature detection (via modernizr) to determine if placeholder is supported. If not, adds support (via jQuery).

appears that if you add this to the command line:

 -loglevel debug

or

 -loglevel verbose

You get more verbose debugging output to the command line.

Filter with glob module:

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

add HeaderStyle in your bound field:

    <asp:BoundField HeaderText="UserId"
                DataField="UserId" 
                SortExpression="UserId">

                <HeaderStyle Width="200px" />

</asp:BoundField>

I was getting from a conflict with join table defined in an association class ( with additional custom fields ) annotation and a join table defined in a many-to-many annotation.

The mapping definitions in two entities with a direct many-to-many relationship appeared to result in the automatic creation of the join table using the 'joinTable' annotation. However the join table was already defined by an annotation in its underlying entity class and I wanted it to use this association entity class's own field definitions so as to extend the join table with additional custom fields.

The explanation and solution is that identified by FMaz008 above. In my situation, it was thanks to this post in the forum 'Doctrine Annotation Question'. This post draws attention to the Doctrine documentation regarding ManyToMany Uni-directional relationships. Look at the note regarding the approach of using an 'association entity class' thus replacing the many-to-many annotation mapping directly between two main entity classes with a one-to-many annotation in the main entity classes and two 'many-to-one' annotations in the associative entity class. There is an example provided in this forum post Association models with extra fields:

public class Person {

  /** @OneToMany(targetEntity="AssignedItems", mappedBy="person") */
  private $assignedItems;

}

public class Items {

    /** @OneToMany(targetEntity="AssignedItems", mappedBy="item") */
    private $assignedPeople;
}

public class AssignedItems {

    /** @ManyToOne(targetEntity="Person")
    * @JoinColumn(name="person_id", referencedColumnName="id")
    */
private $person;

    /** @ManyToOne(targetEntity="Item")
    * @JoinColumn(name="item_id", referencedColumnName="id")
    */
private $item;

}

JBoss and Glassfish are basically full Java EE Application Server whereas Tomcat is only a Servlet container. The main difference between JBoss, Glassfish but also WebSphere, WebLogic and so on respect to Tomcat but also Jetty, was in the functionality that an full app server offer. When you had a full stack Java EE app server you can benefit of all the implementation of the vendor of your choice, and you can benefit of EJB, JTA, CDI(JAVA EE 6+), JPA, JSF, JSP/Servlet of course and so on. With Tomcat on the other hands you can benefit only of JSP/Servlet. However to day with advanced Framework such as Spring and Guice, many of the main advantage of using an a full stack application server can be mitigate, and with the assumption of a one of this framework manly with Spring Ecosystem, you can benefit of many sub project that in the my work experience let me to left the use of a full stack app server in favour of lightweight app server like tomcat.

It is very easy to achieve with built in method SelectAll

Simply cou can write this:

txtTextBox.Focus();
txtTextBox.SelectAll();

And everything in textBox will be selected :)

Exceding the maximum value of a long doesnt throw an exception, instead it cicles back. If you do this:

Long.MAX_VALUE + 1

you will notice that the result is the equivalent to Long.MIN_VALUE.

From here: java number exceeds long.max_value - how to detect?

In IE9+, Chrome or Firefox you can do:

var checkedBoxes = document.querySelectorAll('input[name=mycheckboxes]:checked');

You can get the path of sdcard from this code:

File extStore = Environment.getExternalStorageDirectory();

Then specify the foldername and file name

for e.g:

"/LazyList/"+serialno.get(position).trim()+".jpg"

Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();

You can't get the number of rows returned in a ResultSet without iterating through it. And why would you return a ResultSet without iterating through it? There'd be no point in executing the query in the first place.

A better solution would be to separate persistence from view. Create a separate Data Access Object that handles all the database queries for you. Let it get the values to be displayed in the JTable, load them into a data structure, and then return it to the UI for display. The UI will have all the information it needs then.

You can communicate between windows (tabbed or not) if they have a child-parent relationship.

Create and update a child window:

<html>
<head>
<title>Cross window test script</title>
<script>
var i = 0;
function open_and_run() {
    var w2 = window.open("", "winCounter"); 
    var myVar=setInterval(function(){myTimer(w2)},1000);
}

function myTimer(w2) {
    i++;
    w2.document.body.innerHTML="<center><h1>" + i + "</h1><p></center>";
}
</script>
</head>
<body>
Click to open a new window 
<button onclick="open_and_run();">Test This!</button>    
</body>
</html>

Child windows can use the parent object to communicate with the parent that spawned it, so you could control the music player from either window.

See it in action here: https://jsbin.com/cokipotajo/edit?html,js,output

Here is the example of the code:

public function getItemName()
{
    $this->db->select('Id,Name');
    $this->db->from('item');
    $this->db->where(array('Active' => 1));
    return $this->db->get()->result();
}

static is a heavily overloaded word in C and C++. static variables in the context of a function are variables that hold their values between calls. They exist for the duration of the program.

local variables persist only for the lifetime of a function or whatever their enclosing scope is. For example:

void foo()
{
    int i, j, k;
    //initialize, do stuff
} //i, j, k fall out of scope, no longer exist

Sometimes this scoping is used on purpose with { } blocks:

{ 
   int i, j, k;
   //...
} //i, j, k now out of scope

global variables exist for the duration of the program.

auto is now different in C and C++. auto in C was a (superfluous) way of specifying a local variable. In C++11, auto is now used to automatically derive the type of a value/expression.

<context:component-scan base-package="x.y.z"/>

will work since the rest of the packages are sub packages of "x.y.z". Thus, you dont need to mention each package individually.

This worked for me in Android Studio as well as VS Code. I only had to run these lines in my terminal/command prompt and problem was solved. There was no need to restart any of the IDEs again

• flutter packages get

Optionally you also run.

• flutter upgrade

Use formatting:

"%s" % (x)

Example:

x = time.ctime(); str = "%s" % (x); print str

In case you want to be on the safe side, I recommend to use getopts.

Here is a small example:

    while getopts "x:c" opt; do
      case $opt in
        c)
          echo "-$opt was triggered, deploy to ci account" >&2
          DEPLOY_CI_ACCT="true"
          ;;
            x)
              echo "-$opt was triggered, Parameter: $OPTARG" >&2 
              CMD_TO_EXEC=${OPTARG}
              ;;
            \?)
              echo "Invalid option: -$OPTARG" >&2 
              Usage
              exit 1
              ;;
            :)
              echo "Option -$OPTARG requires an argument." >&2 
              Usage
              exit 1
              ;;
          esac
        done

see more details here for example http://wiki.bash-hackers.org/howto/getopts_tutorial

Try this:

fs.readFile(__dirname + '/../../foo.bar');

Note the forward slash at the beginning of the relative path.

Usually you can find a program under a subdirectory "../bin". System programs are under /usr/bin or /bin. To check where files of mysql package are placed, on RHEL 6 type like this :

rpm -ql mysql (which is the main part of the package)

and the result is a list of "exe" files such as "mysqladmin" tool. About to know the version of the server, run the command:

mysqladmin -u "valid-user" version

This issue arise because we try to delete the parent table still child table data is present. We solve the problem with help of cascade delete.

In model Create method in dbcontext class.

 modelBuilder.Entity<Job>()
                .HasMany<JobSportsMapping>(C => C.JobSportsMappings)
                .WithRequired(C => C.Job)
                .HasForeignKey(C => C.JobId).WillCascadeOnDelete(true);
            modelBuilder.Entity<Sport>()
                .HasMany<JobSportsMapping>(C => C.JobSportsMappings)
                  .WithRequired(C => C.Sport)
                  .HasForeignKey(C => C.SportId).WillCascadeOnDelete(true);

After that,In our API Call

var JobList = Context.Job                       
          .Include(x => x.JobSportsMappings)                                     .ToList();
Context.Job.RemoveRange(JobList);
Context.SaveChanges();

Cascade delete option delete the parent as well parent related child table with this simple code. Make it try in this simple way.

Remove Range which used for delete the list of records in the database Thanks

I had similar situation like Hobhouse. I wanted to use command

 ssh myhost.com 'some_command'

and 'some_command' exists in '/var/some_location' so I tried to append '/var/some_location' in PATH environment by editing '$HOME/.bashrc'

but that wasn't working. because default .bashrc(Ubuntu 10.4 LTS) prevent from sourcing by code like below

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

so If you want to change environment for ssh non-login shell. you should add code above that line.

Kind of an old question, but I can give an answer updated for .NET Core 2.1 with C# 7 standards. Say I have a listing only in appsettings.Development.json such as:

"TestUsers": [
  {
    "UserName": "TestUser",
    "Email": "[email protected]",
    "Password": "P@ssw0rd!"
  },
  {
    "UserName": "TestUser2",
    "Email": "[email protected]",
    "Password": "P@ssw0rd!"
  }
]

I can extract them anywhere that the Microsoft.Extensions.Configuration.IConfiguration is implemented and wired up like so:

var testUsers = Configuration.GetSection("TestUsers")
   .GetChildren()
   .ToList()
    //Named tuple returns, new in C# 7
   .Select(x => 
         (
          x.GetValue<string>("UserName"), 
          x.GetValue<string>("Email"), 
          x.GetValue<string>("Password")
          )
    )
    .ToList<(string UserName, string Email, string Password)>();

Now I have a list of a well typed object that is well typed. If I go testUsers.First(), Visual Studio should now show options for the 'UserName', 'Email', and 'Password'.

I just thought that I would add my own, one-liner (even though there are many other useful answers already).

string ipAddress = new WebClient().DownloadString("http://icanhazip.com");

I've had this problem myself and I've found the great wikipedia page on the subject (in "Common rotations" paragraph:
https://en.wikipedia.org/wiki/Rotation_matrix#Ambiguities

Then I wrote the following code, super verbose in order to have a clear understanding of what is going on.

I hope that you'll find it useful to dig more in the very beautiful and clever one-liner you've posted.

To quickly test it you can copy / paste it here:

# Here we apply the matrix coming from Wikipedia
# for 90 ccw it looks like:
# 0,-1
# 1,0
# What does this mean?
#
# Basically this is how the calculation of the new_x and new_y is happening:
# new_x = (0)(old_x)+(-1)(old_y)
# new_y = (1)(old_x)+(0)(old_y)
#
# If you check the lonely numbers between parenthesis the Wikipedia matrix's numbers
# finally start making sense.
# All the rest is standard formula, the same behaviour will apply to other rotations, just
# remember to use the other rotation matrix values available on Wiki for 180ccw and 170ccw

This answer is a follow up to DaRKoN_'s answer that utilized the object filter:

[ObjectFilter(Param = "postdata", RootType = typeof(ObjectToSerializeTo))]
    public JsonResult ControllerMethod(ObjectToSerializeTo postdata) { ... }

I was having a problem figuring out how to send multiple parameters to an action method and have one of them be the json object and the other be a plain string. I'm new to MVC and I had just forgotten that I already solved this problem with non-ajaxed views.

What I would do if I needed, say, two different objects on a view. I would create a ViewModel class. So say I needed the person object and the address object, I would do the following:

public class SomeViewModel()
{
     public Person Person { get; set; }
     public Address Address { get; set; }
}

Then I would bind the view to SomeViewModel. You can do the same thing with JSON.

[ObjectFilter(Param = "jsonViewModel", RootType = typeof(JsonViewModel))] // Don't forget to add the object filter class in DaRKoN_'s answer.
public JsonResult doJsonStuff(JsonViewModel jsonViewModel)
{
     Person p = jsonViewModel.Person;
     Address a = jsonViewModel.Address;
     // Do stuff
     jsonViewModel.Person = p;
     jsonViewModel.Address = a;
     return Json(jsonViewModel);
}

Then in the view you can use a simple call with JQuery like this:

var json = { 
    Person: { Name: "John Doe", Sex: "Male", Age: 23 }, 
    Address: { Street: "123 fk st.", City: "Redmond", State: "Washington" }
};

$.ajax({
     url: 'home/doJsonStuff',
     type: 'POST',
     contentType: 'application/json',
     dataType: 'json',
     data: JSON.stringify(json), //You'll need to reference json2.js
     success: function (response)
     {
          var person = response.Person;
          var address = response.Address;
     }
});

ASP.NET Core. Approach 1

If your Controller extends ControllerBase or Controller you can use Content(...) method:

[HttpGet]
public ContentResult Index() 
{
    return base.Content("<div>Hello</div>", "text/html");
}

ASP.NET Core. Approach 2

If you choose not to extend from Controller classes, you can create new ContentResult:

[HttpGet]
public ContentResult Index() 
{
    return new ContentResult 
    {
        ContentType = "text/html",
        Content = "<div>Hello World</div>"
    };
}

Legacy ASP.NET MVC Web API

Return string content with media type text/html:

public HttpResponseMessage Get()
{
    var response = new HttpResponseMessage();
    response.Content = new StringContent("<div>Hello World</div>");
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
    return response;
}

You can use:

((int) $var)   ( but in big number it return 2147483647 :-) )

But the best solution is to use:

if (is_numeric($var))
    $var = (isset($var)) ? $var : 0;
else
    $var = 0;

Or

if (is_numeric($var))
    $var = (trim($var) == '') ? 0 : $var;
else
    $var = 0;

You can solve this problem by installing xampp in different Drive .Instead of C Drive .

SELECT *
   FROM   my_table
   WHERE  substr(my_field,1,5) = "abcde";

If you wanted to copy all s3 bucket objects using the command "aws s3 cp s3://bucket-name/data/all-data/ . --recursive" as you mentioned, here is a safe and minimal policy to do that:

{
  "Version": "2012-10-17",
  "Statement": [
      {
          "Effect": "Allow",
          "Action": [
              "s3:ListBucket"
          ],
          "Resource": [
              "arn:aws:s3:::bucket-name"
          ],
          "Condition": {
              "StringLike": {
                  "s3:prefix": "data/all-data/*"
              }
          }
      },
      {
          "Effect": "Allow",
          "Action": [
              "s3:GetObject"
          ],
          "Resource": [
              "arn:aws:s3:::bucket-name/data/all-data/*"
          ]
      }
  ]
}

The first statement in this policy allows for listing objects inside a specific bucket's sub directory. The resource needs to be the arn of the S3 bucket, and to limit listing to only a sub-directory in that bucket you can edit the "s3:prefix" value.

The second statement in this policy allows for getting objects inside of the bucket at a specific sub-directory. This means that anything inside the "s3://bucket-name/data/all-data/" path you will be able to copy. Be aware that this doesn't allow you to copy from parent paths such as "s3://bucket-name/data/".

This solution is specific to limiting use for AWS CLI commands; if you need to limit S3 access through the AWS console or API, then more policies will be needed. I suggest taking a look here: https://aws.amazon.com/blogs/security/writing-iam-policies-grant-access-to-user-specific-folders-in-an-amazon-s3-bucket/.

A similar issue to this can be found here which led me to the solution I am giving. https://github.com/aws/aws-cli/issues/2408

Hope this helps!

Switch to the develop branch:

$ git checkout develop

Creates feature/foo branch of develop.

$ git checkout -b feature/foo develop

merge the changes to develop without a fast-forward

$ git checkout develop
$ git merge --no-ff myFeature

Now push changes to the server

$ git push origin develop
$ git push origin feature/foo

You can read an article i have written for joins in LINQ here

var query = 
from  u in Repo.T_Benutzer
join bg in Repo.T_Benutzer_Benutzergruppen
    on u.BE_ID equals bg.BEBG_BE
into temp
from j in temp.DefaultIfEmpty()
select new
{
    BE_User = u.BE_User,
    BEBG_BG = (int?)j.BEBG_BG// == null ? -1 : j.BEBG_BG
            //, bg.Name 
}

The following is the equivalent using extension methods:

var query = 
Repo.T_Benutzer
.GroupJoin
(
    Repo.T_Benutzer_Benutzergruppen,
    x=>x.BE_ID,
    x=>x.BEBG_BE,
    (o,i)=>new {o,i}
)
.SelectMany
(
    x => x.i.DefaultIfEmpty(),
    (o,i) => new
    {
        BE_User = o.o.BE_User,
        BEBG_BG = (int?)i.BEBG_BG
    }
);

Here's a quick and dirty method that does what you want in a generic way. You'll need to add exception handling and you'll probably want to cache the BeanInfo types in a weakhashmap.

public Map<String, Object> getNonNullProperties(final Object thingy) {
    final Map<String, Object> nonNullProperties = new TreeMap<String, Object>();
    try {
        final BeanInfo beanInfo = Introspector.getBeanInfo(thingy
                .getClass());
        for (final PropertyDescriptor descriptor : beanInfo
                .getPropertyDescriptors()) {
            try {
                final Object propertyValue = descriptor.getReadMethod()
                        .invoke(thingy);
                if (propertyValue != null) {
                    nonNullProperties.put(descriptor.getName(),
                            propertyValue);
                }
            } catch (final IllegalArgumentException e) {
                // handle this please
            } catch (final IllegalAccessException e) {
                // and this also
            } catch (final InvocationTargetException e) {
                // and this, too
            }
        }
    } catch (final IntrospectionException e) {
        // do something sensible here
    }
    return nonNullProperties;
}

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

git 2.7 (Q4 2015) will introduce branch sorting using directly git branch:
See commit aa3bc55, commit aedcb7d, commit 1511b22, commit f65f139, ... (23 Sep 2015), commit aedcb7d, commit 1511b22, commit ca41799 (24 Sep 2015), and commit f65f139, ... (23 Sep 2015) by Karthik Nayak (KarthikNayak).
^{(Merged by Junio C Hamano -- gitster -- in commit 7f11b48, 15 Oct 2015)}

In particular, commit aedcb7d:

branch.c: use 'ref-filter' APIs

Make 'branch.c' use 'ref-filter' APIs for iterating through refs sorting. This removes most of the code used in 'branch.c' replacing it with calls to the 'ref-filter' library.

It adds the option --sort=<key>:

Sort based on the key given.
Prefix - to sort in descending order of the value.

You may use the --sort=<key> option multiple times, in which case the last key becomes the primary key.

The keys supported are the same as those in git for-each-ref.
Sort order defaults to sorting based on the full refname (including refs/... prefix). This lists detached HEAD (if present) first, then local branches and finally remote-tracking branches.

Here:

git branch --sort=-committerdate 

Or (see below with Git 2.19)

# if you are sure to /always/ want to see branches ordered by commits:
git config --global branch.sort -committerdate
git branch

^{(Merged by Junio C Hamano -- gitster -- in commit 415095f, 03 Nov 2015)}

When sorting as per numerical values (e.g. --sort=objectsize) there is no fallback comparison when both refs hold the same value. This can cause unexpected results (i.e. the order of listing refs with equal values cannot be pre-determined) as pointed out by Johannes Sixt ($gmane/280117).

Hence, fallback to alphabetical comparison based on the refname whenever the other criterion is equal.

$ git branch --sort=objectsize

*  (HEAD detached from fromtag)
      branch-two
      branch-one
      master

With Git 2.19, the sort order can be set by default.
git branch supports a config branch.sort, like git tag, which already had a config tag.sort.
See commit 560ae1c (16 Aug 2018) by Samuel Maftoul (``).
^{(Merged by Junio C Hamano -- gitster -- in commit d89db6f, 27 Aug 2018)}

branch.sort:

This variable controls the sort ordering of branches when displayed by git-branch.
Without the "--sort=<value>" option provided, the value of this variable will be used as the default.

To list remote branches, use git branch -r --sort=objectsize. The -r flag causes it to list remote branches instead of local branches.

With Git 2.27 (Q2 2020), "git branch" and other "for-each-ref" variants accepted multiple --sort=<key> options in the increasing order of precedence, but it had a few breakages around "--ignore-case" handling, and tie-breaking with the refname, which have been fixed.

See commit 7c5045f, commit 76f9e56 (03 May 2020) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 6de1630, 08 May 2020)}

ref-filter: apply fallback refname sort only after all user sorts

^{Signed-off-by: Jeff King}

Commit 9e468334b4 ("ref-filter: fallback on alphabetical comparison", 2015-10-30, Git v2.7.0-rc0 -- merge listed in batch #10) taught ref-filter's sort to fallback to comparing refnames.
But it did it at the wrong level, overriding the comparison result for a single "--sort" key from the user, rather than after all sort keys have been exhausted.

This worked correctly for a single "--sort" option, but not for multiple ones.
We'd break any ties in the first key with the refname and never evaluate the second key at all.

To make matters even more interesting, we only applied this fallback sometimes!
For a field like "taggeremail" which requires a string comparison, we'd truly return the result of strcmp(), even if it was 0.
But for numerical "value" fields like "taggerdate", we did apply the fallback. And that's why our multiple-sort test missed this: it uses taggeremail as the main comparison.

So let's start by adding a much more rigorous test. We'll have a set of commits expressing every combination of two tagger emails, dates, and refnames. Then we can confirm that our sort is applied with the correct precedence, and we'll be hitting both the string and value comparators.

That does show the bug, and the fix is simple: moving the fallback to the outer compare_refs() function, after all ref_sorting keys have been exhausted.

Note that in the outer function we don't have an "ignore_case" flag, as it's part of each individual ref_sorting element. It's debatable what such a fallback should do, since we didn't use the user's keys to match.
But until now we have been trying to respect that flag, so the least-invasive thing is to try to continue to do so.
Since all callers in the current code either set the flag for all keys or for none, we can just pull the flag from the first key. In a hypothetical world where the user really can flip the case-insensitivity of keys separately, we may want to extend the code to distinguish that case from a blanket "--ignore-case".

The implementation of "git branch --sort"^(man) wrt the detached HEAD display has always been hacky, which has been cleaned up with Git 2.31 (Q1 2021).

See commit 4045f65, commit 2708ce6, commit 7c269a7, commit d094748, commit 75c50e5 (07 Jan 2021), and commit 08bf6a8, commit ffdd02a (06 Jan 2021) by Ævar Arnfjörð Bjarmason (avar).
^{(Merged by Junio C Hamano -- gitster -- in commit 9e409d7, 25 Jan 2021)}

branch: show "HEAD detached" first under reverse sort

^{Signed-off-by: Ævar Arnfjörð Bjarmason}

Change the output of the likes of "git branch -l --sort=-objectsize"^(man) to show the "(HEAD detached at <hash>)" message at the start of the output.
Before the compare_detached_head() function added in a preceding commit we'd emit this output as an emergent effect.

It doesn't make any sense to consider the objectsize, type or other non-attribute of the "(HEAD detached at <hash>)" message for the purposes of sorting.
Let's always emit it at the top instead.
The only reason it was sorted in the first place is because we're injecting it into the ref-filter machinery so builtin/branch.c doesn't need to do its own "am I detached?" detection.

this line of code on your terminal, solves the problem

$ sudo chown -R $USER:$USER anaconda 3

Another method is:

    function isFloat(float) {
        return /\./.test(float.toString());
    }

Might not be as efficient as the others but another method all the same.

You should use git pull --rebase when

• your changes do not deserve a separate branch

Indeed -- why not then? It's more clear, and doesn't impose a logical grouping on your commits.

Ok, I suppose it needs some clarification. In Git, as you probably know, you're encouraged to branch and merge. Your local branch, into which you pull changes, and remote branch are, actually, different branches, and git pull is about merging them. It's reasonable, since you push not very often and usually accumulate a number of changes before they constitute a completed feature.

However, sometimes--by whatever reason--you think that it would actually be better if these two--remote and local--were one branch. Like in SVN. It is here where git pull --rebase comes into play. You no longer merge--you actually commit on top of the remote branch. That's what it actually is about.

Whether it's dangerous or not is the question of whether you are treating local and remote branch as one inseparable thing. Sometimes it's reasonable (when your changes are small, or if you're at the beginning of a robust development, when important changes are brought in by small commits). Sometimes it's not (when you'd normally create another branch, but you were too lazy to do that). But that's a different question.

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

Are you perhaps looking for:

int Difference = (a-b).Hours;

If your byte array may contain runs of ASCII characters that you'd like to be able to see, you might prefer BAIS (Byte Array In String) format instead of Base64. The nice thing about BAIS is that if all the bytes happen to be ASCII, they are converted 1-to-1 to a string (e.g. byte array {65,66,67} becomes simply "ABC") Also, BAIS often gives you a smaller file size than Base64 (this isn't guaranteed).

After converting the byte array to a BAIS string, write it to JSON like you would any other string.

Here is a Java class (ported from the original C#) that converts byte arrays to string and back.

import java.io.*;
import java.lang.*;
import java.util.*;

public class ByteArrayInString
{
  // Encodes a byte array to a string with BAIS encoding, which 
  // preserves runs of ASCII characters unchanged.
  //
  // For simplicity, this method's base-64 encoding always encodes groups of 
  // three bytes if possible (as four characters). This decision may 
  // unfortunately cut off the beginning of some ASCII runs.
  public static String convert(byte[] bytes) { return convert(bytes, true); }
  public static String convert(byte[] bytes, boolean allowControlChars)

    StringBuilder sb = new StringBuilder();

      else {
        sb.append('\b');
        // Do binary encoding in groups of 3 bytes
        for (;; b = get(bytes,i++)) {

The most basic way to iterate over a hash is as follows:

hash.each do |key, value|
  puts key
  puts value
end

So I just solved my own "SMTP connection failure" error and I wanted to post the solution just in case it helps anyone else.

I used the EXACT code given in the PHPMailer example gmail.phps file. It worked simply while I was using MAMP and then I got the SMTP connection error once I moved it on to my personal server.

All of the Stack Overflow answers I read, and all of the troubleshooting documentation from PHPMailer said that it wasn't an issue with PHPMailer. That it was a settings issue on the server side. I tried different ports (587, 465, 25), I tried 'SSL' and 'TLS' encryption. I checked that openssl was enabled in my php.ini file. I checked that there wasn't a firewall issue. Everything checked out, and still nothing.

The solution was that I had to remove this line:

$mail->isSMTP();

Now it all works. I don't know why, but it works. The rest of my code is copied and pasted from the PHPMailer example file.

try this declare the function outside the ready event.

    $(document).ready(function(){    
       setInterval(swapImages(),1000); 
    });


    function swapImages(){

    var active = $('.active'); 
    var next = ($('.active').next().length > 0) ? $('.active').next() :         $('#siteNewsHead img:first');
    active.removeClass('active');
    next.addClass('active');
}

This solution is similar to walid2mi (thank you for inspiration), but allows the standard console input by the Read-Host cmdlet.

pros:

• can be run like standard .cmd file
• only one file for batch and powershell script
• powershell script may be multi-line (easy to read script)
• allows the standard console input (use the Read-Host cmdlet by standard way)

cons:

• requires powershell version 2.0+

Commented and runable example of batch-ps-script.cmd:

<# : Begin batch (batch script is in commentary of powershell v2.0+)
@echo off
: Use local variables
setlocal
: Change current directory to script location - useful for including .ps1 files
cd %~dp0
: Invoke this file as powershell expression
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
: Restore environment variables present before setlocal and restore current directory
endlocal
: End batch - go to end of file
goto:eof
#>
# here start your powershell script

# example: include another .ps1 scripts (commented, for quick copy-paste and test run)
#. ".\anotherScript.ps1"

# example: standard input from console
$variableInput = Read-Host "Continue? [Y/N]"
if ($variableInput -ne "Y") {
    Write-Host "Exit script..."
    break
}

# example: call standard powershell command
Get-Item .

Snippet for .cmd file:

<# : batch script
@echo off
setlocal
cd %~dp0
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
endlocal
goto:eof
#>
# here write your powershell commands...

This is a guess :)

Is it because the ID is a string? What happens if you change it to int?

I mean:

 public int Id { get; set; }

A FD (functional dependency) that holds in a relation is partial when removing one of the determining attributes gives a FD that holds in the relation. A FD that isn't partial is full.

Eg: If {A,B} ? {C} but also {A} ? {C} then {C} is partially functionally dependent on {A,B}.

Eg: Here's a relation value where that example condition holds. (A FD holds in a relation variable when it holds in every value that can arise.)

A  B  C
1  1  1
1  2  1
2  1  1

The non-trivial FDs that hold: {A,B} determines {C}, {B,C}, {A,C} & {A,B,C}; {A}, {B} & {} also determine {C}. Of those: {A,B} ? {C} is partial per {A} ? {C}, {B} ? {C} & {} ? {C}; {A} ? {C} & {B} ? {C} are partial per {} ? {C}; the others are full.

A functional dependency X ? Y is a full functional dependency if removal of any attribute A from X means that the dependency does not hold any more; that is, for any attribute A e X, (X – {A}) does not functionally determine Y. A functional dependency X ? Y is a partial dependency if some attribute A e X can be removed from X and the dependency still holds; that is, for some A e X, (X – {A}) ? Y.

-- FUNDAMENTALS OF Database Systems SIXTH EDITION Ramez Elmasri & Navathe

Notice that whether a FD is full vs partial doesn't depend on CKs (candidate keys), let alone one CK that you might be calling the PK (primary key).

(A definition of 2NF is that every non-CK attribute is fully functionally determined by every CK. Observe that the only CK is {A,B} & the only non-CK attribute C is partially dependent on it so this value is not in 2NF & indeed it is the lossless join of components/projections onto {A,B} & {A,C}, onto {A,B} & {B,C} & onto {A,B} & {C}.)

(Beware that that textbook's definition of "transitive FD" does not define the same sort of thing as the standard definition of "transitive FD".)

I found that calling of stored procedures in code-first approach is not convenient.

I prefer to use Dapper instead.

The following code was written with Entity Framework:

var clientIdParameter = new SqlParameter("@ClientId", 4);

var result = context.Database
.SqlQuery<ResultForCampaign>("GetResultsForCampaign @ClientId", clientIdParameter)
.ToList();

The following code was written with Dapper:

return Database.Connection.Query<ResultForCampaign>(
            "GetResultsForCampaign ",
            new
            {
                ClientId = 4
            },
            commandType: CommandType.StoredProcedure);
    

I believe the second piece of code is simpler to understand.

Environment.Exit(exitCode); //exit code 0 is a proper exit and 1 is an error

If you include the library System.Data.Entity you can use an overload of the Include() method which takes a lambda expression instead of a string. You can then Select() over children with Linq expressions rather than string paths.

return DatabaseContext.Applications
     .Include(a => a.Children.Select(c => c.ChildRelationshipType));

That is because you are trying to access the plugin before it's loaded. You should try making a call to it when the DOM is loaded by surrounding it with this:

$(document).ready(function(){
    $("#colorpicker").colorpicker();
}

After the first if statement instead of typing "if" type "elif" and then it should work.

Ex.

`    while 1:
    date=input("Example: March 21 | What is the date? ")
if date=="June 21":
    sd="23.5° North Latitude
elif date=="March 21" | date=="September 21":
    sd="0° Latitude"
elif date=="December 21":
    sd="23.5° South Latitude"
elif sd:
    print sd `

I have created a class that solves this problem. Just set it as a delegate of your navigation controller, and implement simple one or two methods in your view controller - that will get called when the view is about to be shown or has been shown via NavigationController

Here's the GIST showing the code

awk is very cool, but why not keep it simple?

num=$(echo $var | grep -o "," | wc -l)

This is standards compliant and cross-browser safe.

Example: http://jsfiddle.net/kv9pw/

var span = document.getElementById('someID');

while( span.firstChild ) {
    span.removeChild( span.firstChild );
}
span.appendChild( document.createTextNode("some new content") );

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

(Source)

Make a call to the DB searching with myid (Id of the row) and get back specific columns:

var columns = db.Notifications
                .Where(x => x.Id == myid)
                .Select(n => new { n.NotificationTitle, 
                                   n.NotificationDescription, 
                                   n.NotificationOrder });

Try using RUN /bin/sh instead of bash.

Another solution is to monitor processes via the proc filesystem (safer than ps/grep combo); when you start a process it has a corresponding folder in /proc/$pid, so the solution could be

#!/bin/bash
....
doSomething &
local pid=$!
while [ -d /proc/$pid ]; do # While directory exists, the process is running
    doSomethingElse
    ....
else # when directory is removed from /proc, process has ended
    wait $pid
    local exit_status=$?
done
....

Now you can use the $exit_status variable however you like.

I'm not sure if this works for you, but when I do small solo PHP projects with Eclipse, the first thing I set up is an Ant script for deploying the project to a remote testing environment. I code away locally, and whenever I want to test it, I just hit the shortcut which updates the remote site.

Eclipse has good Ant support out of the box, and the scripts aren't hard to make.

def func(*args): 
    pass

When you define a function this way, *args will be array of arguments passed to the function. This allows your function to work without knowing ahead of time how many arguments are going to be passed to it.

You do this with keyword arguments too, using **kwargs:

def func2(**kwargs): 
    pass

See: Arbitrary argument lists

In your case, you've defined a class which is acting like a dictionary. The dict.pop method is defined as pop(key[, default]).

Your method doesn't use the default parameter. But, by defining your method with *args and passing *args to dict.pop(), you are allowing the caller to use the default parameter.

In other words, you should be able to use your class's pop method like dict.pop:

my_a = a()
value1 = my_a.pop('key1')       # throw an exception if key1 isn't in the dict
value2 = my_a.pop('key2', None) # return None if key2 isn't in the dict

    public class MainClass {

        public static void main(String args[]) {

          Thread t = Thread.currentThread();
          t.setName("My Thread");

          t.setPriority(1);

          System.out.println("current thread: " + t);

          int active = Thread.activeCount();
          System.out.println("currently active threads: " + active);
          Thread all[] = new Thread[active];
          Thread.enumerate(all);

          for (int i = 0; i < active; i++) {
             System.out.println(i + ": " + all[i]);
          }
       }
   }

To run wget command in PHP you have to do following steps :

1) Allow apache server to use wget command by adding it in sudoers list.

2) Check "exec" function enabled or exist in your PHP config.

3) Run "exec" command as root user i.e. sudo user

Below code sample as per ubuntu machine

#Add apache in sudoers list to use wget command
~$ sudo nano /etc/sudoers
#add below line in the sudoers file
www-data ALL=(ALL) NOPASSWD: /usr/bin/wget


##Now in PHP file run wget command as 
exec("/usr/bin/sudo wget -P PATH_WHERE_WANT_TO_PLACE_FILE URL_OF_FILE");

DESCRIBE <table>; 

This is acutally a shortcut for:

SHOW COLUMNS FROM <table>;

In any case, there are three possible values for the "Key" attribute:

1. PRI
2. UNI
3. MUL

The meaning of PRI and UNI are quite clear:

• PRI => primary key
• UNI => unique key

The third possibility, MUL, (which you asked about) is basically an index that is neither a primary key nor a unique key. The name comes from "multiple" because multiple occurrences of the same value are allowed. Straight from the MySQL documentation:

If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

There is also a final caveat:

If more than one of the Key values applies to a given column of a table, Key displays the one with the highest priority, in the order PRI, UNI, MUL.

As a general note, the MySQL documentation is quite good. When in doubt, check it out!

In my case, I had 2 different test projects in the solution. Project 1 tests could be found, but Project 2 tests could not. I found that first Unloading the test Project 1, then closing VS > clearing my temp files > re-open solution > rebuild, allowed VS to discover my Project 2 tests.

I'm assuming something must be conflicting between the two test projects and this was the quickest way to get me up and running in a few minutes. The kinks can be worked out later :).

Use a colon:

: ${A:=hello}

The colon is a null command that does nothing and ignores its arguments. It is built into bash so a new process is not created.

Warning: jQuery, not standard JavaScript

element.offsetLeft and element.offsetTop are the pure javascript properties for finding an element's position with respect to its offsetParent; being the nearest parent element with a position of relative or absolute

Alternatively, you can always use Zepto to get the position of an element AND its parent, and simply subtract the two:

var childPos = obj.offset();
var parentPos = obj.parent().offset();
var childOffset = {
    top: childPos.top - parentPos.top,
    left: childPos.left - parentPos.left
}

This has the benefit of giving you the offset of a child relative to its parent even if the parent isn't positioned.

This worked for me (I'm using Ubuntu 14.04):

first install libffi-dev libssl-dev libpython2.7-dev:

sudo apt-get install libffi-dev libssl-dev libpython2.7-dev

then inside virtualenv:

pip install cryptography
pip install pyopenssl ndg-httpsclient pyasn1

I know this is an old question, but it worries me that there are no properly correct answers here. Most answers just talk about iterating through all the documents and saving each of them individually, which is a BAD idea if you have more than a few documents, and the process gets repeated for even one in many requests.

MongoDB specifically has a batchInsert() call for inserting multiple documents, and this should be used from the native mongodb driver. Mongoose is built on this driver, and it doesn't have support for batch inserts. It probably makes sense as it is supposed to be a Object document modelling tool for MongoDB.

Solution: Mongoose comes with the native MongoDB driver. You can use that driver by requiring it require('mongoose/node_modules/mongodb') (not too sure about this, but you can always install the mongodb npm again if it doesn't work, but I think it should) and then do a proper batchInsert

This function should do the trick if you want to specify a particular sheet. I took the solution from user6432984 and modified it to not throw any errors. I am using Excel 2016 so it may not work for older versions:

Function findLastRow(ByVal inputSheet As Worksheet) As Integer
    findLastRow = inputSheet.cellS(inputSheet.Rows.Count, 1).End(xlUp).Row
End Function

This is the code to run if you are already working in the sheet you want to find the last row of:

Dim lastRow as Integer
lastRow = cellS(Rows.Count, 1).End(xlUp).Row

I think you are misinterpreting the source of the error; rExternalTotal appears to be equal to a single cell. rReportData.offset(0,0) is equal to rReportData
rReportData.offset(261,0).end(xlUp) is likely also equal to rReportData, as you offset by 261 rows and then use the .end(xlUp) function which selects the top of a contiguous data range.
If you are interested in the sum of just a column, you can just refer to the whole column:

dExternalTotal = Application.WorksheetFunction.Sum(columns("A:A"))

or

dExternalTotal = Application.WorksheetFunction.Sum(columns((rReportData.column))

The worksheet function sum will correctly ignore blank spaces.

Let me know if this helps!

I know it's an old question but maybe someone can use this solution:

int size = 0; // Fill all bits with zero (0)
size = ~size; // Negate all bits, thus all bits are set to one (1)

So far we have -1 as result 'till size is a signed int.

size = (unsigned int)size >> 1; // Shift the bits of size one position to the right.

As Standard says, bits that are shifted in are 1 if variable is signed and negative and 0 if variable would be unsigned or signed and positive.

As size is signed and negative we would shift in sign bit which is 1, which is not helping much, so we cast to unsigned int, forcing to shift in 0 instead, setting the sign bit to 0 while letting all other bits remain 1.

cout << size << endl; // Prints out size which is now set to maximum positive value.

We could also use a mask and xor but then we had to know the exact bitsize of the variable. With shifting in bits front, we don't have to know at any time how many bits the int has on machine or compiler nor need we include extra libraries.

awk -F: '{print $2}' <<< $var

I assume "direction" is "ASC" or "DESC" and dt contains a column named "colName"

public static DataTable resort(DataTable dt, string colName, string direction)
{
    DataTable dtOut = null;
    dt.DefaultView.Sort = colName + " " + direction;
    dtOut = dt.DefaultView.ToTable();
    return dtOut;
}

OR without creating dtOut

public static DataTable resort(DataTable dt, string colName, string direction)
{
    dt.DefaultView.Sort = colName + " " + direction;
    dt = dt.DefaultView.ToTable();
    return dt;
}

In Swift 3 you can do this,

let date = Date()
let hour = Calendar.current.component(.hour, from: date)

I have actually done this using a bit of sleight of hand: a single lookup table with 16 entries will suffice and all you have to do is break the binary rep into nibbles (4-bit tuples). The complexity is in fact O(1) and I wrote a C++ template which was specialized on the size of the integer you wanted (in # bits)… makes it a constant expression instead of indetermined.

fwiw you can use the fact that (i & -i) will return you the LS one-bit and simply loop, stripping off the lsbit each time, until the integer is zero — but that’s an old parity trick.

You can do it if you wrap your text into a span like:

a {_x000D_
  color: red;_x000D_
  text-decoration: underline;_x000D_
}_x000D_
span {_x000D_
  color: blue;_x000D_
  text-decoration: none;_x000D_
}

<a href="#">_x000D_
  <span>Text</span>_x000D_
</a>

If you specify image as well as build, then Compose names the built image with the webapp and optional tag specified in image:

build: ./dir
image: webapp:tag

This results in an image named webapp and tagged tag, built from ./dir.

The Android Gradle plugin is still in beta and this may simply be a bug. For me, setting ANDROID_HOME works, but we may be on different versions (please try again with the most recent version and let me know if it works or not).

It's also worth setting the environment variable ANDROID_SDK as well as ANDROID_HOME.

I have seen issues with this on some machines, so we do create local.properties in those cases - I have also noticed that the latest version of Android Studio will create this file for you and fill in the sdk.dir property.

Note that you shouldn't check local.properties into version control, we have added it to our gitignore so that it doesn't interfere with porting the code across systems which you rightfully identified as a potential problem.

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

I think that if the parameter identifies a specific entity you should use a path variable. For example, to get all the posts on my blog I request

GET: myserver.com/myblog/posts

to get the post with id = 123, I would request

GET: myserver.com/myblog/posts/123

but to filter my list of posts, and get all posts since Jan 1, 2013, I would request

GET: myserver.com/myblog/posts?since=2013-01-01

In the first example "posts" identifies a specific entity (the entire collection of blog posts). In the second example, "123" also represents a specific entity (a single blog post). But in the last example, the parameter "since=2013-01-01" is a request to filter the posts collection not a specific entity. Pagination and ordering would be another good example, i.e.

GET: myserver.com/myblog/posts?page=2&order=backward

Hope that helps. :-)

You could do:

select sum(counts) total_records from (
    select count(*) as counts
    from temptable
    group by column_1, column_2, column_3, column_4
) as tmp

An easy short hand way would be to use +x It keeps the sign intact as well as the decimal numbers. The other alternative is to use parseFloat(x). Difference between parseFloat(x) and +x is for a blank string +x returns 0 where as parseFloat(x) returns NaN.

Here is an equivalent optional declaration in Swift:

var middleName: String?

This declaration creates a variable named middleName of type String. The question mark (?) after the String variable type indicates that the middleName variable can contain a value that can either be a String or nil. Anyone looking at this code immediately knows that middleName can be nil. It's self-documenting!

If you don't specify an initial value for an optional constant or variable (as shown above) the value is automatically set to nil for you. If you prefer, you can explicitly set the initial value to nil:

var middleName: String? = nil

To expand on the above answer_{copied by Shakti}, I have actually been able to measure a performance difference between the two functions.

I was testing performance of variations of the solution to this question and found that the standard deviation and maximum runtimes were larger when using CAST.

_{*Times in milliseconds, rounded to nearest 1/300th of a second as per the precision of the DateTime type}

Try using the ISO string

var isodate = new Date().toISOString()

This answer accepts some edge cases that others don't:

• Only thousand separator: 1.000.000 => 1000000
• Exponentials: 1.000e3 => 1000e3 (1 million)

Once upon a time there was Unix and in this good old Unix there was lots of overhead for processes, so what some clever people did was to create threads, which would share the same address space with the parent process and they only needed a reduced context switch, which would make the context switch more efficient.

In a contemporary Linux (2.6.x) there is not much difference in performance between a context switch of a process compared to a thread (only the MMU stuff is additional for the thread). There is the issue with the shared address space, which means that a faulty pointer in a thread can corrupt memory of the parent process or another thread within the same address space.

A process is protected by the MMU, so a faulty pointer will just cause a signal 11 and no corruption.

I would in general use processes (not much context switch overhead in Linux, but memory protection due to MMU), but pthreads if I would need a real-time scheduler class, which is a different cup of tea all together.

Why do you think threads are have such a big performance gain on Linux? Do you have any data for this, or is it just a myth?

I too have been through this pain - if the query is dynamically generated (e.g. Hibernate Criteria) then I couldn't find a practical way to do it.

The good news for me was that I was only investigating union to solve a performance problem when using an 'or' in an Oracle database.

The solution Patrick posted (combining the results programmatically using a set) while ugly (especially since I wanted to do results paging as well) was adequate for me.

I had the same problem. Check out the comment in https://gist.github.com/khernyo/4226923#comment-812526

It says:

for gradle android plugin v0.3 use "com.android.build.gradle.tasks.PackageApplication"

That should fix your problem.

Your JRE_HOME does not need to point to the "bin" directory. Just set it to C:\Program Files\Java\jre1.8.0_25

I guess this is where you are pointing at ..

<div id="divActivites" name="divActivites" style="border:thin">
    <textarea id="inActivities" name="inActivities" style="border:solid">
    </textarea> 
</div> 

Well. it must be written as border-width:thin

Here you go with the link (click here) check out the different types of Border-styles

you can also set the border width by writing the width in terms of pixels.. (like border-width:1px), minimum width is 1px.

STEP1: I created a field of type varbinary in table

STEP2: I created a stored procedure to accept a parameter of type sql_variant

STEP3: In my front end asp.net page, I created a sql data source parameter of object type

        <tr>
        <td>
            UPLOAD DOCUMENT</td>
        <td>
            <asp:FileUpload ID="FileUpload1" runat="server" />
            <asp:Button ID="btnUpload" runat="server" Text="Upload" />
            <asp:SqlDataSource ID="sqldsFileUploadConn" runat="server" 
                ConnectionString="<%$ ConnectionStrings: %>" 
                InsertCommand="ph_SaveDocument"     
               InsertCommandType="StoredProcedure">
                <InsertParameters>
                    <asp:Parameter Name="DocBinaryForm" Type="Object" />
                </InsertParameters>

             </asp:SqlDataSource>
        </td>
        <td>
            &nbsp;</td>
    </tr>

STEP 4: In my code behind, I try to upload the FileBytes from FileUpload Control via this stored procedure call using a sql data source control

      Dim filebytes As Object
      filebytes = FileUpload1.FileBytes()
      sqldsFileUploadConn.InsertParameters("DocBinaryForm").DefaultValue = filebytes.ToString
      Dim uploadstatus As Int16 = sqldsFileUploadConn.Insert()

               ' ... code continues ... '

You mentioned Ubuntu so I'm going to guess you installed the PostgreSQL packages from Ubuntu through apt.

If so, the postgres PostgreSQL user account already exists and is configured to be accessible via peer authentication for unix sockets in pg_hba.conf. You get to it by running commands as the postgres unix user, eg:

sudo -u postgres createuser owning_user
sudo -u postgres createdb -O owning_user dbname

This is all in the Ubuntu PostgreSQL documentation that's the first Google hit for "Ubuntu PostgreSQL" and is covered in numerous Stack Overflow questions.

(You've made this question a lot harder to answer by omitting details like the OS and version you're on, how you installed PostgreSQL, etc.)

I was facing same problem but accidentlty I sorted this problem. 1) Login in github 2) Click on Fork Button at Top Right. 3) After above step you can see Clone or download in Green color under <> Code Tab.

Here is sample of raw pointer iterator.

You shouldn't use iterator class to work with raw pointers!

#include <iostream>
#include <vector>
#include <list>
#include <iterator>
#include <assert.h>

template<typename T>
class ptr_iterator
    : public std::iterator<std::forward_iterator_tag, T>
{
    typedef ptr_iterator<T>  iterator;
    pointer pos_;
public:
    ptr_iterator() : pos_(nullptr) {}
    ptr_iterator(T* v) : pos_(v) {}
    ~ptr_iterator() {}

    iterator  operator++(int) /* postfix */         { return pos_++; }
    iterator& operator++()    /* prefix */          { ++pos_; return *this; }
    reference operator* () const                    { return *pos_; }
    pointer   operator->() const                    { return pos_; }
    iterator  operator+ (difference_type v)   const { return pos_ + v; }
    bool      operator==(const iterator& rhs) const { return pos_ == rhs.pos_; }
    bool      operator!=(const iterator& rhs) const { return pos_ != rhs.pos_; }
};

template<typename T>
ptr_iterator<T> begin(T *val) { return ptr_iterator<T>(val); }


template<typename T, typename Tsize>
ptr_iterator<T> end(T *val, Tsize size) { return ptr_iterator<T>(val) + size; }

Raw pointer range based loop workaround. Please, correct me, if there is better way to make range based loop from raw pointer.

template<typename T>
class ptr_range
{
    T* begin_;
    T* end_;
public:
    ptr_range(T* ptr, size_t length) : begin_(ptr), end_(ptr + length) { assert(begin_ <= end_); }
    T* begin() const { return begin_; }
    T* end() const { return end_; }
};

template<typename T>
ptr_range<T> range(T* ptr, size_t length) { return ptr_range<T>(ptr, length); }

And simple test

void DoIteratorTest()
{
    const static size_t size = 10;
    uint8_t *data = new uint8_t[size];
    {
        // Only for iterator test
        uint8_t n = '0';
        auto first = begin(data);
        auto last = end(data, size);
        for (auto it = first; it != last; ++it)
        {
            *it = n++;
        }

        // It's prefer to use the following way:
        for (const auto& n : range(data, size))
        {
            std::cout << " char: " << static_cast<char>(n) << std::endl;
        }
    }
    {
        // Only for iterator test
        ptr_iterator<uint8_t> first(data);
        ptr_iterator<uint8_t> last(first + size);
        std::vector<uint8_t> v1(first, last);

        // It's prefer to use the following way:
        std::vector<uint8_t> v2(data, data + size);
    }
    {
        std::list<std::vector<uint8_t>> queue_;
        queue_.emplace_back(begin(data), end(data, size));
        queue_.emplace_back(data, data + size);
    }
}

Yahoo has a tutorial on making calls to their REST services using PHP:

Make Yahoo! Web Service REST Calls with PHP

I have not used it myself, but Yahoo is Yahoo and should guarantee for at least some level of quality. They don't seem to cover PUT and DELETE requests, though.

Also, the User Contributed Notes to curl_exec() and others contain lots of good information.
