This warning may also be shown if jQuery is declared more than once in your code. The second jQuery declaration prevents bootstrap.js from working correctly.

As a novice user it took me a while to understand how to fix this in a correct way. After searching and understating many answers on SO I came out with the Following steps that you need to follow to fix the issue.

Please Note:

Although the simplest solution is to update the Info.plist of android studio . But it is not recommended and not the correct way to fix it .

Official statement- "Please note: Do not edit Info.plist to pick a different version. That will break not only the application signature, but also future patch updates to your installation."

First Solution : If you run your Android Studio from command line, you can add these two lines into your .bash_profile

$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk

$ open /Applications/Android\ Studio.app

From next time whenever you open your terminal your studio will start automatically.

Second Solution: If you want to run Android Studio from UI(by click on Icon) follow below steps:

1. Open script editor on mac(one can find it in spotlight)

2. Copy past the below line

   do shell script "launchctl setenv STUDIO_JDK /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk"

Note :- Change the jdk version according to your version. To check which version you are using open terminal and run the following command

java -version

3.Now save (?+s) as File format: Application. Finally open System Settings ? Users & Groups ? Login Items and add your new application that you have just created.

4. Log-off and login again or you can run that application manually as well..

woolaaaa…Its done.

ruario's answer

I just ran into this on a .NET MVC project. The root cause was conflicting versions of NuGet packages. I had a solution with several projects. Each of the projects had some NuGet packages. In one project I had a version of the Enterprise Library Semantic Logging package, and in two other projects (that reference the first) I had older versions of the same package. It all compiles without error, but it gave a mysterious "Method not found" error when I tried to use the package.

The fix was to remove the old NuGet packages from the two projects, so that it was only included in the one project that actually needed it. (Also I did a clean rebuild of the whole solution.)

I would like to add an answer to this thread to specifically mention which of the above threads helped me solve the issue and the order in which they can be followed to properly understand the root cause and fix it once and for all:

I was able to get my rich preview while sharing the link on social media with this solution.

I followed various options in this thread and below are the closest to the right answer and they all contributed to the end result:

1. Tags required (Main tag to focus on - og:image)
2. Image parameters
3. Tool that will definitely help
4. How to correctly give the image path
5. Root cause and solution

This will hopefully save someone the time needed to scroll through and find the right set of answers and the effort required for all the trial and errors.

Since the event object "evt" is not passed from the parameter, is it still possible to obtain this object?

No, not reliably. IE and some other browsers make it available as window.event (not $(window.event)), but that's non-standard and not supported by all browsers (famously, Firefox does not).

You're better off passing the event object into the function:

<a href="#" onclick="myFunc(event, 1,2,3)">click</a>

That works even on non-IE browsers because they execute the code in a context that has an event variable (and works on IE because event resolves to window.event). I've tried it in IE6+, Firefox, Chrome, Safari, and Opera. Example: http://jsbin.com/iwifu4

But your best bet is to use modern event handling:

HTML:

<a href="#">click</a>

JavaScript using jQuery (since you're using jQuery):

$("selector_for_the_anchor").click(function(event) {
    // Call `myFunc`
    myFunc(1, 2, 3);

    // Use `event` here at the event handler level, for instance
    event.stopPropagation();
});

...or if you really want to pass event into myFunc:

$("selector_for_the_anchor").click(function(event) {
    myFunc(event, 1, 2, 3);
});

The selector can be anything that identifies the anchor. You have a very rich set to choose from (nearly all of CSS3, plus some). You could add an id or class to the anchor, but again, you have other choices. If you can use where it is in the document rather than adding something artificial, great.

What you actually have is an Activity (even if it looks like a Dialog), therefore you should call setFinishOnTouchOutside(false) from your activity if you want to keep it open when the background activity is clicked.

EDIT: This only works with android API level 11 or greater

As mentioned above it wont work for primitive types where 0/NO could be a valid value. I am using this code.

NSUserDefaults *defaults= [NSUserDefaults standardUserDefaults];
if([[[defaults dictionaryRepresentation] allKeys] containsObject:@"mykey"]){

    NSLog(@"mykey found");
}

Try use this:

<html>
<body>
   <input type="text" style="direction: rtl;" value="1">
   <input type="text" style="direction: rtl;" value="10">
   <input type="text" style="direction: rtl;" value="100">
</body>
</html>

It looks to me, like you're working in windows in which case a new line character in not simply \n but rather \r\n

You can always get the correct new line character through System.getProperty("line.separator") for example.

This statement is much cleaner and more readable for me:

select * from my_table where ISNULL(NULLIF(some_col, ''));

On Windows 10, I have docker installed. I am running Jnekins on a container and I encountered the same error message. Here is a step by step guide to resolve this issue:

Step 1: Open gitbash and run docker run -p 8080:8080 -p 50000:50000 jenkins.

Step 2: Open a new terminal.

Step 3: Do "docker ps" to get list of the running container. Copy the container id.

Step 4: Now if you do "docker exec -it {container id} sh" or "docker exec -it {container id} bash" you will get an error message similar to " the input device is not a TTY. If you are using mintty, try prefixing the command with 'winpty'"

Step 5: Run command " $winpty docker exec -it {container id} sh"

vola !! You are now inside the terminal.

Need Key & Value in Iteration

Use entrySet() to iterate through Map and need to access value and key:

Map<String, Person> hm = new HashMap<String, Person>();

hm.put("A", new Person("p1"));
hm.put("B", new Person("p2"));
hm.put("C", new Person("p3"));
hm.put("D", new Person("p4"));
hm.put("E", new Person("p5"));

Set<Map.Entry<String, Person>> set = hm.entrySet();

for (Map.Entry<String, Person> me : set) {
  System.out.println("Key :"+me.getKey() +" Name : "+ me.getValue().getName()+"Age :"+me.getValue().getAge());

}

Need Key in Iteration

If you want just to iterate over keys of map you can use keySet()

for(String key: map.keySet()) {
     Person value = map.get(key); 
}

Need Value in Iteration

If you just want to iterate over values of map you can use values()

for(Person person: map.values()) {

}

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

This code was adapted from Ozgrid

and as jkf points out, from Mr Excel

This is what I came up with. Here is a fiddle.

First, I need three wrapper elements for both a square shape and centered text.

<div><div><div>Lorem ipsum dolor sit amet, consectetuer adipiscing elit,
sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat
volutpat.</div></div></div>

This is the stylecheet. It makes use of two techniques, one for square shapes and one for centered text.

body > div {
    position:relative;
    height:0;
    width:50%; padding-bottom:50%;
}

body > div > div {
    position:absolute; top:0;
    height:100%; width:100%;
    display:table;
    border:1px solid #000;
    margin:1em;
}

body > div > div > div{
    display:table-cell;
    vertical-align:middle; text-align:center;
    padding:1em;
}

This looks pretty good to me:

A common problem when creating dynamic web pages (where content is sourced from a database, content management system or external source such as an RSS feed) is that the input text can be too long and cause the page layout to 'break'.

One solution is to truncate the text so that it fits on the page. This sounds simple, but often the results aren't as expected due to words and sentences being cut off at inappropriate points.

What is the len of the equivalent nested list?

len([[2,3,1,0], [2,3,1,0], [3,2,1,1]])

With the more general concept of shape, numpy developers choose to implement __len__ as the first dimension. Python maps len(obj) onto obj.__len__.

X.shape returns a tuple, which does have a len - which is the number of dimensions, X.ndim. X.shape[i] selects the ith dimension (a straight forward application of tuple indexing).

for LocalBroadcastManager

   Intent intent = new Intent("any.action.string");
   LocalBroadcastManager.getInstance(context).
                                sendBroadcast(intent);

and register in onResume

LocalBroadcastManager.getInstance(
                    ActivityName.this).registerReceiver(chatCountBroadcastReceiver, filter);

and Unregister it onStop

LocalBroadcastManager.getInstance(
                ActivityName.this).unregisterReceiver(chatCountBroadcastReceiver);

and recieve it ..

mBroadcastReceiver = new BroadcastReceiver() {

You need to use ajax.

http://api.jquery.com/jQuery.ajax/

<code>
$.ajax({
  url: 'ajax/test.html',
  success: function(data) {
    $('.result').html(data);
    alert('Load was performed.');
  }
});
</code>

I suggest you also take a look at __autoload.
This will clean up the code of requires and includes.

By design it is to be done this way:

OutputStream out = ...;
try (Writer w = new OutputStreamWriter(out, "UTF-8")) {
    w.write("Hello, World!");
} // or w.close(); //close will auto-flush

This : /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i is not working for below Gmail case

[email protected] [email protected]

Below Regex will cover all the E-mail Points: I have tried the all Possible Points and my Test case get also pass because of below regex

I found this Solution from this URL:

Regex Solution link

make clean generally only cleans built files in the directory containing the source code itself, and rarely touches any installed software.

Makefiles generally don't contain a target for uninstallation -- you usually have to do that yourself, by removing the files from the directory into which they were installed. For example, if you built a program and installed it (using make install) into /usr/local, you'd want to look through /usr/local/bin, /usr/local/libexec, /usr/local/share/man, etc., and remove the unwanted files. Sometimes a Makefile includes an uninstall target, but not always.

Of course, typically on a Linux system you install software using a package manager, which is capable of uninstalling software "automagically".

The only thing you can do is obfuscate your code to make it more difficult to read. No matter what you do, if you want the javascript to execute in their browser they'll have to have the code.

for (int i = 0; i < Types.length; i++) {
    if(TYPES[i].equals(userString)){
        return i;
    }
}
return -1;//not found

You can do this too:

return Arrays.asList(Types).indexOf(userSTring);

For MAC or Linux:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--kiosk");
driver = new ChromeDriver(chromeOptions);

For Windows:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-maximized");
driver = new ChromeDriver(chromeOptions);

For anyone like me finding this question the following might be useful.

I had a similar problem and initially tried using location.go and location.replaceState as suggested in other answers here. However I ran into problems when I had to navigate to another page on the app because the navigation was relative to the current route and the current route wasn't being updated by location.go or location.replaceState (the router doesn't know anything about what these do to the URL)

In essence I needed a solution that DIDN'T reload the page/component when the route parameter changed but DID update the route state internally.

I ended up using query parameters. You can find more about it here: https://angular-2-training-book.rangle.io/handout/routing/query_params.html

So if you need to do something like save an order and get an order ID you can update your page URL like shown below. Updating a centre location and related data on a map would be similar

// let's say we're saving an order. Initally the URL is just blah/orders
save(orderId) {
    // [Here we would call back-end to save the order in the database]

    this.router.navigate(['orders'], { queryParams: { id: orderId } });
    // now the URL is blah/orders?id:1234. We don't reload the orders
    // page or component so get desired behaviour of not seeing any 
    // flickers or resetting the page.
}

and you keep track of it within the ngOnInit method like:

ngOnInit() {
    this.orderId = this.route
        .queryParamMap
        .map(params => params.get('id') || null);
    // orderID is up-to-date with what is saved in database now, or if
    // nothing is saved and hence no id query paramter the orderId variable
    // is simply null.
    // [You can load the order here from its ID if this suits your design]
}

If you need to go direct to the order page with a new (unsaved) order you can do:

this.router.navigate(['orders']);

Or if you need to go direct to the order page for an existing (saved) order you can do:

this.router.navigate(['orders'], { queryParams: { id: '1234' } });

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

The connector section has the parameter

maxPostSize

The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Another Limit is:

maxHttpHeaderSize The maximum size of the request and response HTTP header, specified in bytes. If not specified, this attribute is set to 4096 (4 KB).

You find them in

$TOMCAT_HOME/conf/server.xml

You shouldn't really do this but insert in a new record instead and update it that way.
But, if you really need to, you can do the following:

• Disable enforcing FK constraints temporarily (e.g. ALTER TABLE foo WITH NOCHECK CONSTRAINT ALL)
• Then update your PK
• Then update your FKs to match the PK change
• Finally enable back enforcing FK constraints

For mac, Uncheck Offline Work from Preference -> Build, Execution, Deployment -> Build Tools -> Gradle -> Global Gradle Settings

I believe _list.ToList() will make you a copy. You can also query it if you need to such as :

_list.Select("query here").ToList(); 

Anyways, msdn says this is indeed a copy and not simply a reference. Oh, and yes, you will need to lock in the set method as the others have pointed out.

If you are calling this code from a fragment it has it’s own requestPermissions method.

So basic concept is, If you are in an Activity, then call

ActivityCompat.requestPermissions(this,
                            permissionsList,
                            permissionscode);

and if in a Fragment, just call

requestPermissions(permissionsList,
                            permissionscode);

Use cin.get() to read the next character.

However, for this problem, it is very inefficient to read a character at a time. Use the istream::read() instead.

int main()
{
   char a[10];
   cin.read(a, sizeof(a));
   for(int i = 0; i < 10; i++)
   {
       if(a[i] == ' ')
          cout<<"It is a space!!!"<<<endl;
   }
   return 0;
}

And use == to check equality, not =.

A simple solution is using the scalers offered by the sklearn.preprocessing library.

scaler = sk.MinMaxScaler(feature_range=(0, 250))
scaler = scaler.fit(X)
X_scaled = scaler.transform(X)
# Checking reconstruction
X_rec = scaler.inverse_transform(X_scaled)

The error X_rec-X will be zero. You can adjust the feature_range for your needs, or even use a standart scaler sk.StandardScaler()

Create a layout-land directory and put the landscape version of your layout XML file in that directory.

Are you sure it's not a Table-Valued Function?

The reason I ask:

CREATE FUNCTION dbo.chk_mgr(@mgr VARCHAR(50)) 
RETURNS @mgr_table TABLE (mgr_name VARCHAR(50))
AS
BEGIN 
  INSERT @mgr_table (mgr_name) VALUES ('pointy haired boss') 
  RETURN
END 
GO

SELECT dbo.chk_mgr('asdf')
GO

Result:

Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function 
or aggregate "dbo.chk_mgr", or the name is ambiguous.

However...

SELECT * FROM dbo.chk_mgr('asdf')

You can use filterfalse function from itertools module

Example

import random
from itertools import filterfalse

random.seed(42)

data = [random.randrange(5) for _ in range(10)]
clean = [*filterfalse(lambda i: i == 0, data)]
print(f"Remove 0s\n{data=}\n{clean=}\n")


clean = [*filterfalse(lambda i: i in (0, 1), data)]
print(f"Remove 0s and 1s\n{data=}\n{clean=}")

Output:

Remove 0s
data=[0, 0, 2, 1, 1, 1, 0, 4, 0, 4]
clean=[2, 1, 1, 1, 4, 4]

Remove 0s and 1s
data=[0, 0, 2, 1, 1, 1, 0, 4, 0, 4]
clean=[2, 4, 4]

I think you want:

items.GroupBy(item => item.Order.Customer)
     .Select(group => new { Customer = group.Key, Items = group.ToList() })
     .ToList() 

If you want to continue use the overload of GroupBy you are currently using, you can do:

items.GroupBy(item => item.Order.Customer, 
              (key, group) =>  new { Customer = key, Items = group.ToList() })
     .ToList() 

...but I personally find that less clear.

Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:

• Elements outside the __init__ method are static elements; they belong to the class.
• Elements inside the __init__ method are elements of the object (self); they don't belong to the class.

You'll see it more clearly with some code:

class MyClass:
    static_elem = 123

    def __init__(self):
        self.object_elem = 456

c1 = MyClass()
c2 = MyClass()

# Initial values of both elements
>>> print c1.static_elem, c1.object_elem 
123 456
>>> print c2.static_elem, c2.object_elem
123 456

# Nothing new so far ...

# Let's try changing the static element
MyClass.static_elem = 999

>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456

# Now, let's try changing the object element
c1.object_elem = 888

>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456

As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.

SELECT `name` FROM `table` WHERE `name` LIKE '%Stylus % 2100%'

Given this piece of HTML code:

<a href='https://facebook.com/'>Facebook</a>
<a href='https://google.ca/'>Google</a>
<input type='text' placeholder='an input box'>

We can use this JavaScript:

function checkTabPress(e) {
    'use strict';
    var ele = document.activeElement;

    if (e.keyCode === 9 && ele.nodeName.toLowerCase() === 'a') {
        console.log(ele.href);
    }
}

document.addEventListener('keyup', function (e) {
    checkTabPress(e);
}, false);

I have bound an event listener to the document element for the keyUp event, which triggers a function to check if the Tab key was pressed (or technically, released).

The function checks the currently focused element and whether the NodeName is a. If so, it enters the if block and, in my case, writes the value of the href property to the JavaScript console.

Here's a jsFiddle

The key is the sql query, which you will set up as a string:

$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";

Note that there are a lot of ways to specify NOT. Another one that works just as well is:

$sqlquery = "SELECT field1, field2 FROM table WHERE columnA != 'x' AND columbB != 'y'";

Here is a full example of how to use it:

$link = mysql_connect($dbHost,$dbUser,$dbPass) or die("Unable to connect to database");
mysql_select_db("$dbName") or die("Unable to select database $dbName");
$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";
$result=mysql_query($sqlquery);

while ($row = mysql_fetch_assoc($result) {
//do stuff
}

You can do whatever you would like within the above while loop. Access each field of the table as an element of the $row array which means that $row['field1'] will give you the value for field1 on the current row, and $row['field2'] will give you the value for field2.

Note that if the column(s) could have NULL values, those will not be found using either of the above syntaxes. You will need to add clauses to include NULL values:

$sqlquery = "SELECT field1, field2 FROM table WHERE (NOT columnA = 'x' OR columnA IS NULL) AND (NOT columbB = 'y' OR columnB IS NULL)";

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

Hi I ran into the same problem when I was developing an application and wanted to install it on a remote PC, I fixed it by doing the following:

1) Goto your registry, locate: HKLM\System\CurrentControlSet\Services\EventLog\Application(???YOUR_SERVICE_OR_APP_NAME???)

Note that "(???YOUR_SERVICE_OR_APP_NAME???)" is your application service name as you defined it when you created your .NET deployment, for example, if you named your new application "My new App" then the key would be: HKLM\System\CurrentControlSet\Services\EventLog\Application\My New app

Note2: Depending on which eventLog you are writing into, you may find on your DEV box, \Application\ (as noted above), or also (\System) or (\Security) depending on what event your application is writing into, mostly, (\Application) should be fine all the times.

2) Being on the key above, From the menu; Select "FILE" -> "Export", and then save the file. (Note: This would create your necessary registry settings when the application would need to access this key to write into the Event Viewer), the new file will be a .REG file, for the argument sake, call it "My New App.REG"

3) When deploying on PRODuction, consult the Server's System's administrator (SA), hand over the "My New App.REG" file along with the application, and ask the SA to install this REG file, once done (as admin) this would create the key for your applicaion.

4) Run your application, it should not need to access anything else other than this key.

Problem should be resolved by now.

Cause:

When developing an application that writes anything into the EventLog, it would require a KEY for it under the Eventlog registry if this key isn't found, it would try to create it, which then fails for having no permissions to do so. The above process, is similar to deploying an application (manually) whereas we are creating this ourselves, and no need to have a headache since you are not tweaking the registry by adding permissions to EVERYONE which is a securty risk on production servers.

I hope this helps resolving it.

this solved it to me:

sudo apt-get install libglfw3
sudo apt-get install libglfw3-dev

JSONP is a way of getting around the browser's same-origin policy. How? Like this:

The goal here is to make a request to otherdomain.com and alert the name in the response. Normally we'd make an AJAX request:

$.get('otherdomain.com', function (response) {
  var name = response.name;
  alert(name);
});

However, since the request is going out to a different domain, it won't work.

We can make the request using a <script> tag though. Both <script src="otherdomain.com"></script> and $.get('otherdomain.com') will result in the same request being made:

GET otherdomain.com

Q: But if we use the <script> tag, how could we access the response? We need to access it if we want to alert it.

A: Uh, we can't. But here's what we could do - define a function that uses the response, and then tell the server to respond with JavaScript that calls our function with the response as its argument.

Q: But what if the server won't do this for us, and is only willing to return JSON to us?

A: Then we won't be able to use it. JSONP requires the server to cooperate.

Q: Having to use a <script> tag is ugly.

A: Libraries like jQuery make it nicer. Ex:

$.ajax({
    url: "http://otherdomain.com",
    jsonp: "callback",
    dataType: "jsonp",
    success: function( response ) {
        console.log( response );
    }
});

It works by dynamically creating the <script> tag DOM element.

Q: <script> tags only make GET requests - what if we want to make a POST request?

A: Then JSONP won't work for us.

Q: That's ok, I just want to make a GET request. JSONP is awesome and I'm going to go use it - thanks!

A: Actually, it isn't that awesome. It's really just a hack. And it isn't the safest thing to use. Now that CORS is available, you should use it whenever possible.

with a form, just set method to "post"

<form action="blah.php" method="post">
  <input type="text" name="data" value="mydata" />
  <input type="submit" />
</form>

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

You might also want to take a look at NativeBase (http://nativebase.io). This a library of components for React Native that include some nice layout structure (http://nativebase.io/docs/v2.0.0/components#anatomy) including Headers and Footers.

It's a bit like Bootstrap for Mobile.

Sections don't work in partial views and that's by design. You may use some custom helpers to achieve similar behavior, but honestly it's the view's responsibility to include the necessary scripts, not the partial's responsibility. I would recommend using the @scripts section of the main view to do that and not have the partials worry about scripts.

To use the IntelliJ Java decompiler from the command line for a jar package follow the instructions provided here: https://github.com/JetBrains/intellij-community/tree/master/plugins/java-decompiler/engine

My project is based on iOS 7 This helps me

[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];

Then put a subview into cell as separator!

I do a lot of such presentation and use Monaco for code and Chalkboard for text (within a template that, overall, has only small changes from the Blackboard one supplied with Keynote). Look at any of my presentations' PDFs (e.g. this one) and you can decide whether you like the effect.

You can also do it with jQuery:

var options = ["1", "2", "3", "4", "5"];
$('#select').empty();
$.each(options, function(i, p) {
    $('#select').append($('<option></option>').val(p).html(p));
});

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.

After some googling I found this link:

The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged

So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.

The solution provided by ebeneditos works perfectly.

But if you have cv2.imwrite() in several sections of a large code snippet and you want to change the path where the images get saved, you will have to change the path at every occurrence of cv2.imwrite() individually.

As Soltius stated, here is a better way. Declare a path and pass it as a string into cv2.imwrite()

import cv2
import os
img = cv2.imread('1.jpg', 1)
path = 'D:/OpenCV/Scripts/Images'
cv2.imwrite(os.path.join(path , 'waka.jpg'), img)
cv2.waitKey(0)

Now if you want to modify the path, you just have to change the path variable.

Edited based on solution provided by Kallz

It's trivial to do with LINQ, which is implemented in PHP in several libraries, including YaLinqo*. It allows performing SQL-like queries on arrays and objects. The groubBy function is designed specifically for grouping, you just need to specify the field you want to group by:

$grouped_array = from($array)->groupBy('$v["id"]')->toArray();

Where '$v["id"]' is a shorthand for function ($v) { return $v["id"]; } which this library supports.

The result will be exactly like in the accepted answer, just with less code.

_{* developed by me}

If Ruby is installed, then

ruby yourfile.rb

where yourfile.rb is the file containing the ruby code.

Or

irb

to start the interactive Ruby environment, where you can type lines of code and see the results immediately.

So I take it if the user enters 2, you want the output to be something like:

!!
!!
!!
!!

Correct?

To get that, you would need something like:

rows = 4
times_to_repeat = int(raw_input("How many times to repeat per row? ")

for i in range(rows):
    print "!" * times_to_repeat

That would result in:

How many times to repeat per row?
>> 4
!!!!
!!!!
!!!!
!!!!

I have not tested this, but it should run error free.

$( 'input[name="testGroup"]:radio' ).on('change', function(e) {_x000D_
     console.log(e.type);_x000D_
     return false;_x000D_
});

This syntax is a little more flexible to handle events. Not only can you observe "changes", but also other types of events can be controlled here too by using one single event handler. You can do this by passing the list of events as arguments to the first parameter. See jQuery On

Secondly, .change() is a shortcut for .on( "change", handler ). See here. I prefer using .on() rather than .change because I have more control over the events.

Lastly, I'm simply showing an alternative syntax to attach the event to the element.

I would suggest to use ASIHTTPRequest

ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications.

It is suitable performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The included ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.

Please note, that the original author discontinued with this project. See the followring post for reasons and alternatives: http://allseeing-i.com/%5Brequest_release%5D;

Personally I am a big fan of AFNetworking

Completing the answer:

String selectedOption = new Select(driver.findElement(By.xpath("Type the xpath of the drop-down element"))).getFirstSelectedOption().getText();

Assert.assertEquals("Please select any option...", selectedOption);

You can use for loop to untar multiple .tar.gz files to another folder. The following code will take /destination/folder/path as an argument to the script and untar all .tar.gz files present at the current location in /destination/folder/path.

if [ $# -ne 1 ];
 then
 echo "invalid argument/s"
 echo "Usage: ./script-file-name.sh /target/directory"
 exit 0
fi
for file in *.tar.gz
do
    tar -zxvf "$file" --directory $1
done

You want the non-locale-aware floatval function:

float floatval ( mixed $var ) - Gets the float value of a string.

Example:

$string = '122.34343The';
$float  = floatval($string);
echo $float; // 122.34343

You could do this:

import itertools

ids = set(existing_answer.answer.id for existing_answer in existing_question_answers)
answers = itertools.ifilter(lambda x: x.id not in ids, answers)

Read when QuerySets are evaluated and note that it is not good to load the whole result into memory (e.g. via list()).

Reference: itertools.ifilter

Update with regard to the comment:

There are various ways to do this. One (which is probably not the best one in terms of memory and time) is to do exactly the same :

answer_ids = set(answer.id for answer in answers)
existing_question_answers = filter(lambda x: x.answer.id not in answers_id, existing_question_answers)

There is a great background image that is identical to the UITextView used for sending text messages in iPhone's Messages app. You'll need Adobe Illustrator to get & modify it. iphone ui vector elements

If you mean File.separator and File.pathSeparator then:

• File.pathSeparator is used to separate individual file paths in a list of file paths. Consider on windows, the PATH environment variable. You use a ; to separate the file paths so on Windows File.pathSeparator would be ;.

• File.separator is either / or \ that is used to split up the path to a specific file. For example on Windows it is \ or C:\Documents\Test

Use "\n" instead of '\n'

First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).

Neither is supported by Windows command-line ftp.exe. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.

Using WinSCP, your batch file would look like (for SFTP):

echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat

And the batch file:

winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%

Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP% syntax), the batch file simplifies to:

winscp.com /log=ftpcmd.log /command ^
    "open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

For the purpose of -hostkey switch, see verifying the host key in script.

Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:

All you need to tweak is the source file name (use the %TIMESTAMP% syntax as shown previously) and the path to the log file.

For FTPS, replace the sftp:// in the open command with ftpes:// (explicit TLS/SSL) or ftps:// (implicit TLS/SSL). Remove the -hostkey switch.

winscp.com /log=ftpcmd.log /command ^
    "open ftps://ftp_user:[email protected] -explicit" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

You may need to add the -certificate switch, if your server's certificate is not issued by a trusted authority.

Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.

See a complete conversion guide from ftp.exe to WinSCP.

You should also read the Guide to automating file transfers to FTP server or SFTP server.

Note to using %TIMESTAMP#yyyymmdd% instead of %date%: A format of %date% variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date% resolves to ct 06. 11. 2014, what might be problematic when used as a part of a file name.

For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd% resolves to 20170515 on any locale.

(I'm the author of WinSCP)

because of possible data leaks best solution via cursor:

 Cursor cursor = null;
    try {
          cursor =  .... some query (raw or not your choice)
          return cursor.moveToNext();
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }

1) From API KITKAT u can use resources try()

try (cursor = ...some query)

2) if u query against VARCHAR TYPE use '...' eg. COLUMN_NAME='string_to_search'

3) dont use moveToFirst() is used when you need to start iterating from beggining

4) avoid getCount() is expensive - it iterates over many records to count them. It doesn't return a stored variable. There may be some caching on a second call, but the first call doesn't know the answer until it is counted.

HEAD is short for current branch so git push -u origin HEAD works. Now to avoid this typing everytime I use alias:

git config --global alias.pp 'push -u origin HEAD'

After this, everytime I want to push branch created via git -b branch I can push it using:

git pp

Hope this saves time for someone!

public static String timeDifference(long timeDifference1) {
long timeDifference = timeDifference1/1000;
int h = (int) (timeDifference / (3600));
int m = (int) ((timeDifference - (h * 3600)) / 60);
int s = (int) (timeDifference - (h * 3600) - m * 60);

return String.format("%02d:%02d:%02d", h,m,s);

I have experienced that a drop-down menu, referring to a control range (for example after copying sheets from one workbook to another), will keep that cell reference after copying the worksheet, and keeps a data connection which is invisible in "Connections". I found this in the "Search" menu in the ribbon, where an arrow can be selected to mark objects. Underneath the arrow is a menu selection to see all the objects listed in a panel. Then you can delete those unwanted objects and the data source/connection is gone...

Check out php-ip-2-country from code.google. The database they provide is updated daily, so it is not necessary to connect to an outside server for the check if you host your own SQL server. So using the code you would only have to type:

<?php
$ip = $_SERVER['REMOTE_ADDR'];

if(!empty($ip)){
        require('./phpip2country.class.php');

        /**
         * Newest data (SQL) avaliable on project website
         * @link http://code.google.com/p/php-ip-2-country/
         */
        $dbConfigArray = array(
                'host' => 'localhost', //example host name
                'port' => 3306, //3306 -default mysql port number
                'dbName' => 'ip_to_country', //example db name
                'dbUserName' => 'ip_to_country', //example user name
                'dbUserPassword' => 'QrDB9Y8CKMdLDH8Q', //example user password
                'tableName' => 'ip_to_country', //example table name
        );

        $phpIp2Country = new phpIp2Country($ip,$dbConfigArray);
        $country = $phpIp2Country->getInfo(IP_COUNTRY_NAME);
        echo $country;
?>

Example Code (from the resource)

<?
require('phpip2country.class.php');

$dbConfigArray = array(
        'host' => 'localhost', //example host name
        'port' => 3306, //3306 -default mysql port number
        'dbName' => 'ip_to_country', //example db name

);

$phpIp2Country = new phpIp2Country('213.180.138.148',$dbConfigArray);

print_r($phpIp2Country->getInfo(IP_INFO));

According to the json.org specification, your return is invalid. The names are always quoted, so you should be returning

{ "title": "One", "key": "1" }

and

[ { "title": "One", "key": "1" }, { "title": "Two", "key": "2" } ]

This may not be the problem with your setup, since you say one of them works now, but it should be fixed for correctness in case you need to switch to another JSON parser in the future.

You can have multiple <context:property-placeholder /> elements instead of explicitly declaring multiple PropertiesPlaceholderConfigurer beans.

// usage: log('inside coolFunc',this,arguments);
// http://paulirish.com/2009/log-a-lightweight-wrapper-for-consolelog/
window.log = function(){
  log.history = log.history || [];   // store logs to an array for reference
  log.history.push(arguments);
  if(this.console){
    console.log( Array.prototype.slice.call(arguments) );
  }
};

Using window.log will allow you to perform the same action as console.log, but it checks if the browser you are using has the ability to use console.log first, so as not to error out for compatibility reasons (IE 6, etc.).

You can try U2U Query Builder http://www.u2u.net/res/Tools/CamlQueryBuilder.aspx you can use their API U2U.SharePoint.CAML.Server.dll and U2U.SharePoint.CAML.Client.dll

I didn't use them but I'm sure it will help you achieving your task.

Those look much like Bonjour / mDNS requests to me. Those packets use multicast IP address 224.0.0.251 and port 5353.

The most likely source for this is Apple iTunes, which comes pre-installed on Mac computers (and is a popular install on Windows machines as well). Apple iTunes uses it to discover other iTunes-compatible devices in the same WiFi network.

mDNS is also used (primarily by Apple's Mac and iOS devices) to discover mDNS-compatible devices such as printers on the same network.

If this is a Linux box instead, it's probably the Avahi daemon then. Avahi is ZeroConf/Bonjour compatible and installed by default, but if you don't use DNS-SD or mDNS, it can be disabled.

When page IsPostback, the following code work correctly. But when page first loading, there is not multiple newline in the textarea. Bug

textBox1.Text = "Line1\r\n\r\n\r\nLine2";

The problem is that you are calling GetGridData from a background thread. This method accesses several WPF controls which are bound to the main thread. Any attempt to access them from a background thread will lead to this error.

In order to get back to the correct thread you should use SynchronizationContext.Current.Post. However in this particular case it seems like the majority of the work you are doing is UI based. Hence you would be creating a background thread just to go immediately back to the UI thread and do some work. You need to refactor your code a bit so that it can do the expensive work on the background thread and then post the new data to the UI thread afterwards

Although in most general cases the error is quite clearly that file handles have not been closed, I just encountered an instance with JDK7 on Linux that well... is sufficiently ****ed up to explain here.

The program opened a FileOutputStream (fos), a BufferedOutputStream (bos) and a DataOutputStream (dos). After writing to the dataoutputstream, the dos was closed and I thought everything went fine.

Internally however, the dos, tried to flush the bos, which returned a Disk Full error. That exception was eaten by the DataOutputStream, and as a consequence the underlying bos was not closed, hence the fos was still open.

At a later stage that file was then renamed from (something with a .tmp) to its real name. Thereby, the java file descriptor trackers lost track of the original .tmp, yet it was still open !

To solve this, I had to first flush the DataOutputStream myself, retrieve the IOException and close the FileOutputStream myself.

I hope this helps someone.

Let's assume you have install target, which is a very common in makefiles. If you do not use .PHONY, and a file named install exists in the same directory as the Makefile, then make install will do nothing. This is because Make interprets the rule to mean "execute such-and-such recipe to create the file named install". Since the file is already there, and its dependencies didn't change, nothing will be done.

However if you make the install target PHONY, it will tell the make tool that the target is fictional, and that make should not expect it to create the actual file. Hence it will not check whether the install file exists, meaning: a) its behavior will not be altered if the file does exist and b) extra stat() will not be called.

Generally all targets in your Makefile which do not produce an output file with the same name as the target name should be PHONY. This typically includes all, install, clean, distclean, and so on.

I've always used sort_by. You need to wrap the #sort_by output with Hash[] to make it output a hash, otherwise it outputs an array of arrays. Alternatively, to accomplish this you can run the #to_h method on the array of tuples to convert them to a k=>v structure (hash).

hsh ={"a" => 1000, "b" => 10, "c" => 200000}
Hash[hsh.sort_by{|k,v| v}] #or hsh.sort_by{|k,v| v}.to_h

There is a similar question in "How to sort a Ruby Hash by number value?".

Do you mean like:

$val1 = rand( 1, 10 ); // gives one integer between 1 and 10
$val2 = rand( 20, 40 ) ; // gives one integer between 20 and 40

or perhaps:

$range = range( 1, 10 ); // gives array( 1, 2, ..., 10 );
$range2 = range( 20, 40 ); // gives array( 20, 21, ..., 40 );

or maybe:

$truth1 = $val >= 1 && $val <= 10; // true if 1 <= x <= 10
$truth2 = $val >= 20 && $val <= 40; // true if 20 <= x <= 40

suppose you wanted:

$in_range = ( $val > 1 && $val < 10 ) || ( $val > 20 && $val < 40 ); // true if 1 < x < 10 OR 20 < x < 40

If you need exact '/' delimiters, for example: 09/20/2013 rather than 09.20.2013, use escape sequence '/':

Dim regDate As Date = Date.Now()
Dim strDate As String = regDate.ToString("MM\/dd\/yyyy")

You could use get twice:

example_dict.get('key1', {}).get('key2')

This will return None if either key1 or key2 does not exist.

Note that this could still raise an AttributeError if example_dict['key1'] exists but is not a dict (or a dict-like object with a get method). The try..except code you posted would raise a TypeError instead if example_dict['key1'] is unsubscriptable.

Another difference is that the try...except short-circuits immediately after the first missing key. The chain of get calls does not.

If you wish to preserve the syntax, example_dict['key1']['key2'] but do not want it to ever raise KeyErrors, then you could use the Hasher recipe:

class Hasher(dict):
    # https://stackoverflow.com/a/3405143/190597
    def __missing__(self, key):
        value = self[key] = type(self)()
        return value

example_dict = Hasher()
print(example_dict['key1'])
# {}
print(example_dict['key1']['key2'])
# {}
print(type(example_dict['key1']['key2']))
# <class '__main__.Hasher'>

Note that this returns an empty Hasher when a key is missing.

Since Hasher is a subclass of dict you can use a Hasher in much the same way you could use a dict. All the same methods and syntax is available, Hashers just treat missing keys differently.

You can convert a regular dict into a Hasher like this:

hasher = Hasher(example_dict)

and convert a Hasher to a regular dict just as easily:

regular_dict = dict(hasher)

Another alternative is to hide the ugliness in a helper function:

def safeget(dct, *keys):
    for key in keys:
        try:
            dct = dct[key]
        except KeyError:
            return None
    return dct

So the rest of your code can stay relatively readable:

safeget(example_dict, 'key1', 'key2')

If you tried myList|length and myList|length_is and its not getting desired results, then you should use myList.count

How are you loading this page? Is it getting anything on POST to load? If it's not, then the $name = $_POST['Name']; assignation doesn't have any 'Name' on POST.

In my case the flask version was only visible under so I had to go to C:\Users\\AppData\Local\flask\venv\Scripts>pip freeze --local

Another solution you can use is SQL Developer.

With it, you have the ability to import from a csv file (other delimited files are available).

Just open the table view, then:

• choose actions
• import data
• find your file
• choose your options.

You have the option to have SQL Developer do the inserts for you, create an sql insert script, or create the data for a SQL Loader script (have not tried this option myself).

Of course all that is moot if you can only use the command line, but if you are able to test it with SQL Developer locally, you can always deploy the generated insert scripts (for example).

Just adding another option to the 2 already very good answers.

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

Solution:

To your secondary question

var elem1 = $('#elem1'),
    elem2 = $('#elem2'),
    elem3 = $('#elem3');

You can use the variable as the replacement of selector.

elem1.css({'display':'none'}); //will work

In the below case selector is already stored in a variable.

$(elem1,elem2,elem3).css({'display':'none'}); // will not work

Since ECMA-/Javascript is all about Objects and Contexts (which, are also somekind of Object), every variable is stored in a such called Variable- (or in case of a Function, Activation Object).

So if you create variables like this:

var a = 1,
    b = 2,
    c = 3;

In the Global scope (= NO function context), you implicitly write those variables into the Global object (= window in a browser).

Those can get accessed by using the "dot" or "bracket" notation:

var name = window.a;

or

var name = window['a'];

This only works for the global object in this particular instance, because the Variable Object of the Global Object is the window object itself. Within the Context of a function, you don't have direct access to the Activation Object. For instance:

function foobar() {
   this.a = 1;
   this.b = 2;

   var name = window['a']; // === undefined
   alert(name);
   name = this['a']; // === 1
   alert(name);
}

new foobar();

new creates a new instance of a self-defined object (context). Without new the scope of the function would be also global (=window). This example would alert undefined and 1 respectively. If we would replace this.a = 1; this.b = 2 with:

var a = 1,
    b = 2;

Both alert outputs would be undefined. In that scenario, the variables a and b would get stored in the Activation Object from foobar, which we cannot access (of course we could access those directly by calling a and b).

In my case eclipse is not showing parent class function on $this, so I perform below mention points and it starts works:-

I go to my /var/www/ folder and check for .metadata folder (Here check the .log file and it shows) Resource is out of sync with the file system: 1. Go to Eclipse --> Project --> Clean 2. Windows -- preferences --> General --> Workspace --> And set it to "Refresh Automatically"

After that boom - things gets start working :)

If you want to load variables from other files too then ado this :- Eclipse-->Windows-->Preferences-->Php-->Editor-->Content Assist --> and check "show variable from other files"

Then it will show element , variables and other functions also.

Python lists are heterogeneous that is the elements in the same list can be any type of object. The expression: c.append(c) appends the object c what ever it may be to the list. In the case it makes the list itself a member of the list.

The expression c += c adds two lists together and assigns the result to the variable c. The overloaded + operator is defined on lists to create a new list whose contents are the elements in the first list and the elements in the second list.

So these are really just different expressions used to do different things by design.

You need to add the port number to every address you type in your browser when you have changed the default port from port 80.

For example: localhost:8000/cc .

A little edition here is that it should be 8080 in place of 8000. For example - http://localhost:8080/phpmyadmin/

The solution is pretty straightforward. Suppose you want to use the "autumn" colormap scheme. The standard version:

cmap = matplotlib.cm.autumn

To reverse the colormap color spectrum, use get_cmap() function and append '_r' to the colormap title like this:

cmap_reversed = matplotlib.cm.get_cmap('autumn_r')

The easiest way to accomplish this on android is by adding the following code to your custom style :

@android:color/transparent

If you are trying to get the drawable from the view where the image is set as,

ivshowing.setBackgroundResource(R.drawable.one);

then the drawable will return only null value with the following code...

   Drawable drawable = (Drawable) ivshowing.getDrawable();

So, it's better to set the image with the following code, if you wanna retrieve the drawable from a particular view.

 ivshowing.setImageResource(R.drawable.one);

only then the drawable will we converted exactly.

SET UP THE REPOSITORY

For Ubuntu 14.04/16.04/16.10/17.04:

sudo add-apt-repository "deb [arch=amd64] \
     https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

For Ubuntu 17.10:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable"

Add Docker’s official GPG key:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Then install

$ sudo apt-get update && sudo apt-get -y install docker-ce

Your for loop looks good.

A possible while loop to accomplish the same thing:

int sum = 0;
int i = 1;
while (i <= 100) {
    sum += i;
    i++;
}
System.out.println("The sum is " + sum);

A possible do while loop to accomplish the same thing:

int sum = 0;
int i = 1;
do {
    sum += i;
    i++;
} while (i <= 100);
System.out.println("The sum is " + sum);

The difference between the while and the do while is that, with the do while, at least one iteration is sure to occur.

If you are doing it from command line,

try -

python -m pip install selenium

or (for Python3 and above)

python3 -m pip install selenium

Instead of SELECT * FROM MyTable WHERE Column1 CONTAINS 'word1 word2 word3', add And in between those words like:

SELECT * FROM MyTable WHERE Column1 CONTAINS 'word1 And word2 And word3'

for details, see here https://msdn.microsoft.com/en-us/library/ms187787.aspx

UPDATE

For selecting phrases, use double quotes like:

SELECT * FROM MyTable WHERE Column1 CONTAINS '"Phrase one" And word2 And "Phrase Two"'

p.s. you have to first enable Full Text Search on the table before using contains keyword. for more details, See here https://docs.microsoft.com/en-us/sql/relational-databases/search/get-started-with-full-text-search

Use ViewPager. It's work for me.

final ViewPager viewPager = (ViewPager) getActivity().findViewById(R.id.vp_pager); 
button = (Button)result.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        viewPager.setCurrentItem(1);
    }
});

If you'll be using the standard shell of the operating system, you can get the result much faster rather than using pure pythonic way.

Example for Windows:

import os
import subprocess

def get_num_files(path):
    cmd = 'DIR \"%s\" /A-D /B /S | FIND /C /V ""' % path
    return int(subprocess.check_output(cmd, shell=True))

Having said, I'd rather see developers build kick-ass apps that are well-designed and follow separation of concerns, than see them waste time arguing about MV* nonsense. And for this reason, I hereby declare AngularJS to be MVW framework - Model-View-Whatever. Where Whatever stands for "whatever works for you".

If you update your libs, you want to commit the lockfile too. It basically states that your project is locked to those specific versions of the libs you are using.

If you commit your changes, and someone pulls your code and updates the dependencies, the lockfile should be unmodified. If it is modified, it means that you have a new version of something.

Having it in the repository assures you that each developer is using the same versions.

Use brackets. So to look for 75%

WHERE MyCol LIKE '%75[%]%'

This is simpler than ESCAPE and common to most RDBMSes.

Consider the following in order to handle the case of an empty string:

>>> my_string = 'A,B,C,D,E'
>>> my_string.split(",") if my_string else []
['A', 'B', 'C', 'D', 'E']
>>> my_string = ""
>>> my_string.split(",") if my_string else []
[]

That would be the tempfile module.

It has functions to get the temporary directory, and also has some shortcuts to create temporary files and directories in it, either named or unnamed.

Example:

import tempfile

print tempfile.gettempdir() # prints the current temporary directory

f = tempfile.TemporaryFile()
f.write('something on temporaryfile')
f.seek(0) # return to beginning of file
print f.read() # reads data back from the file
f.close() # temporary file is automatically deleted here

For completeness, here's how it searches for the temporary directory, according to the documentation:

1. The directory named by the TMPDIR environment variable.
2. The directory named by the TEMP environment variable.
3. The directory named by the TMP environment variable.
4. A platform-specific location:
   • On RiscOS, the directory named by the Wimp$ScrapDir environment variable.
   • On Windows, the directories C:\TEMP, C:\TMP, \TEMP, and \TMP, in that order.
   • On all other platforms, the directories /tmp, /var/tmp, and /usr/tmp, in that order.
5. As a last resort, the current working directory.

Below is a class which will accomplish the very basics of what you want to do when reading data from a MySQL database into a JTable in Java.

import java.awt.*;
import java.sql.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;

public class TableFromMySqlDatabase extends JFrame
{
    public TableFromMySqlDatabase()
    {
        ArrayList columnNames = new ArrayList();
        ArrayList data = new ArrayList();

        //  Connect to an MySQL Database, run query, get result set
        String url = "jdbc:mysql://localhost:3306/yourdb";
        String userid = "root";
        String password = "sesame";
        String sql = "SELECT * FROM animals";

        // Java SE 7 has try-with-resources
        // This will ensure that the sql objects are closed when the program 
        // is finished with them
        try (Connection connection = DriverManager.getConnection( url, userid, password );
            Statement stmt = connection.createStatement();
            ResultSet rs = stmt.executeQuery( sql ))
        {
            ResultSetMetaData md = rs.getMetaData();
            int columns = md.getColumnCount();

            //  Get column names
            for (int i = 1; i <= columns; i++)
            {
                columnNames.add( md.getColumnName(i) );
            }

            //  Get row data
            while (rs.next())
            {
                ArrayList row = new ArrayList(columns);

                for (int i = 1; i <= columns; i++)
                {
                    row.add( rs.getObject(i) );
                }

                data.add( row );
            }
        }
        catch (SQLException e)
        {
            System.out.println( e.getMessage() );
        }

        // Create Vectors and copy over elements from ArrayLists to them
        // Vector is deprecated but I am using them in this example to keep 
        // things simple - the best practice would be to create a custom defined
        // class which inherits from the AbstractTableModel class
        Vector columnNamesVector = new Vector();
        Vector dataVector = new Vector();

        for (int i = 0; i < data.size(); i++)
        {
            ArrayList subArray = (ArrayList)data.get(i);
            Vector subVector = new Vector();
            for (int j = 0; j < subArray.size(); j++)
            {
                subVector.add(subArray.get(j));
            }
            dataVector.add(subVector);
        }

        for (int i = 0; i < columnNames.size(); i++ )
            columnNamesVector.add(columnNames.get(i));

        //  Create table with database data    
        JTable table = new JTable(dataVector, columnNamesVector)
        {
            public Class getColumnClass(int column)
            {
                for (int row = 0; row < getRowCount(); row++)
                {
                    Object o = getValueAt(row, column);

                    if (o != null)
                    {
                        return o.getClass();
                    }
                }

                return Object.class;
            }
        };

        JScrollPane scrollPane = new JScrollPane( table );
        getContentPane().add( scrollPane );

        JPanel buttonPanel = new JPanel();
        getContentPane().add( buttonPanel, BorderLayout.SOUTH );
    }

    public static void main(String[] args)
    {
        TableFromMySqlDatabase frame = new TableFromMySqlDatabase();
        frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
        frame.pack();
        frame.setVisible(true);
    }
}

In the NetBeans IDE which you are using - you will need to add the MySQL JDBC Driver in Project Properties as I display here:

Otherwise the code will throw an SQLException stating that the driver cannot be found.

Now in my example, yourdb is the name of the database and animals is the name of the table that I am performing a query against.

Here is what will be output:

Parting note:

You stated that you were a novice and needed some help understanding some of the basic classes and concepts of Java. I will list a few here, but remember you can always browse the docs on Oracle's site.

• ArrayList
• Vector
• Try-with-resources statement

From the test,

it('should allow passing locals to the expression', inject(function($rootScope) {
  expect($rootScope.$eval('a+1', {a: 2})).toBe(3);

  $rootScope.$eval(function(scope, locals) {
    scope.c = locals.b + 4;
  }, {b: 3});
  expect($rootScope.c).toBe(7);
}));

We also can pass locals for evaluation expression.

You can use checkout or co

$ svn co http://example.com/svn/app-name directory-name

Some short codes:-

1. checkout (co)
2. commit (ci)
3. copy (cp)
4. delete (del, remove,rm)
5. diff (di)

If you want to set backgroundColor of button programmatically then this code will surly help you

Swift 3 and Swift 4

self.yourButton.backgroundColor = UIColor.red

Swift 2.3 or lower

self.yourButton.backgroundColor = UIColor.redColor()

Using RGB

self.yourButton.backgroundColor = UIColor(red: 102/255, green: 250/255, blue: 51/255, alpha: 0.5)

or you can use float values

button.backgroundColor = UIColor(red: 0.4, green: 1.0, blue: 0.2, alpha: 0.5)

Tested code, initially creates a single archive file, then splits it:

 gzip -c file.orig > file.gz
 CHUNKSIZE=1073741824
 PARTCNT=$[$(stat -c%s file.gz) / $CHUNKSIZE]

 # the remainder is taken care of, for example for
 # 1 GiB + 1 bytes PARTCNT is 1 and seq 0 $PARTCNT covers
 # all of file
 for n in `seq 0 $PARTCNT`
 do
       dd if=file.gz of=part.$n bs=$CHUNKSIZE skip=$n count=1
 done

This variant omits creating a single archive file and goes straight to creating parts:

gzip -c file.orig |
    ( CHUNKSIZE=1073741824;
        i=0;
        while true; do
            i=$[i+1];
            head -c "$CHUNKSIZE" > "part.$i";
            [ "$CHUNKSIZE" -eq $(stat -c%s "part.$i") ] || break;
        done; )

In this variant, if the archive's file size is divisible by $CHUNKSIZE, then the last partial file will have file size 0 bytes.

I assume that the main idea is to find if number is negative and display it in correct format.

For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.

$profitLoss = 25000 - 55000;

$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY); 
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)

Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7

I don't think checking the element's own visibility and display properties is good enough for requirement #1, even if you use currentStyle/getComputedStyle. You also have to check the element's ancestors. If an ancestor is hidden, so is the element.

Auth::routes() is just a helper class that helps you generate all the routes required for user authentication. You can browse the code here https://github.com/laravel/framework/blob/5.3/src/Illuminate/Routing/Router.php instead.

Here are the routes

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');

as @DLeh says Use rather

var controller = DependencyResolver.Current.GetService<ControllerB>();

But, giving the controller, a controlller context is important especially when you need to access the User object, Server object, or the HttpContext inside the 'child' controller.

I have added a line of code:

controller.ControllerContext = new ControllerContext(Request.RequestContext, controller);

or else you could have used System.Web to acces the current context too, to access Server or the early metioned objects

NB: i am targetting the framework version 4.6 (Mvc5)

One of the answers in this question might help you. There seems to be a platform agnostic version for python, but I haven't tried it yet.

To kill a session in Oracle, you use the ALTER SYSTEM KILL SESSION command.

Details here: http://www.oracle-base.com/articles/misc/KillingOracleSessions.php

I think you need str.contains, if you need rows where values of column date contains string 07311954:

print df[df['date'].astype(str).str.contains('07311954')]

Or if type of date column is string:

print df[df['date'].str.contains('07311954')]

If you want check last 4 digits for string 1954 in column date:

print df[df['date'].astype(str).str[-4:].str.contains('1954')]

Sample:

print df['date']
0    8152007
1    9262007
2    7311954
3    2252011
4    2012011
5    2012011
6    2222011
7    2282011
Name: date, dtype: int64

print df['date'].astype(str).str[-4:].str.contains('1954')
0    False
1    False
2     True
3    False
4    False
5    False
6    False
7    False
Name: date, dtype: bool

Adding

solved my problem ;)

My problem was :

    let dateNow = NSDate()
    let calendar = NSCalendar.currentCalendar()
    let hour = calendar.component(NSCalendarUnit.Hour, fromDate: dateNow)
    let minute = calendar.component(NSCalendarUnit.Minute, fromDate: dateNow)
    print(String(hour))
    print(String(minute))

Please do take note of the cast to String in the print statement, you can easily assign that value to variables, like this:

var hoursString = String(hour)
var minutesString = String(minute)

Then you can concatenate values like this:

var compoundString = "\(hour):\(minute)"
print(compoundString)

In VB, math.round has additional arguments to specify number of decimal places and rounding method. Math.Round(10.665, 2, MidpointRounding.AwayFromZero) will return 10.67 . If the number is a decimal or single data type, math.round returns a decimal data type. If it is double, it returns double data type. That might be important if option strict is on.

The result of (10.665).ToString("n2") rounds away from zero to give "10.67". without additional arguments math.round returns 10.66, which could lead to unwanted discrepancies.

It means display width

Whether you use tinyint(1) or tinyint(2), it does not make any difference.

I always use tinyint(1) and int(11), I used several mysql clients (navicat, sequel pro).

It does not mean anything AT ALL! I ran a test, all above clients or even the command-line client seems to ignore this.

But, display width is most important if you are using ZEROFILL option, for example your table has following 2 columns:

A tinyint(2) zerofill

B tinyint(4) zerofill

both columns has the value of 1, output for column A would be 01 and 0001 for B, as seen in screenshot below :)

You clone a repository with git clone [url]. Like so,

$ git clone https://github.com/libgit2/libgit2

If the command should work with both tabs and spaces as the delimiter I would use awk:

awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile

As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for loop:

awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile

If you want to use cut, you need to use the -f option:

cut -f100-105 myfile > outfile

If the field delimiter is different from TAB you need to specify it using -d:

cut -d' ' -f100-105 myfile > outfile

Check the man page for more info on the cut command.

For a non-javascript solution, try putting a <button disabled>Submit</button> into your form, positioned before any other submit buttons/inputs. I suggest immediately after the <form> opening tag (and using CSS to hide it, accesskey='-1' to get it out of the tab sequence, etc)

AFAICT, user agents look for the first submit button when ENTER is hit in an input, and if that button is disabled will then stop looking for another.

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)

https://www.w3.org/TR/html5/forms.html#implicit-submission

However, I do know that Safari 10 MacOS misbehaves here, submitting the form even if the default button is disabled.

So, if you can assume javascript, insert <button onclick="return false;">Submit</button> instead. On ENTER, the onclick handler will get called, and since it returns false the submission process stops. Browsers I've tested this with won't even do the browser-validation thing (focussing the first invalid form control, displaying an error message, etc).

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

if you want to get the whole period:

    from sqlalchemy import and_, func

    query = DBSession.query(User).filter(and_(func.date(User.birthday) >= '1985-01-17'),\
                                              func.date(User.birthday) <= '1988-01-17'))

That means range: 1985-01-17 00:00 - 1988-01-17 23:59

You can have a look at dozer which is a

Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Chrome 76+

Last year I used Linblow's answer (2018-Oct-19) to successfully discover my local IP via javascript. However, recent Chrome updates (76?) have wonked this method so that it now returns an obfuscated IP, such as: 1f4712db-ea17-4bcf-a596-105139dfd8bf.local

If you have full control over your browser, you can undo this behavior by turning it off in Chrome Flags, by typing this into your address bar:

chrome://flags

and DISABLING the flag Anonymize local IPs exposed by WebRTC

In my case, I require the IP for a TamperMonkey script to determine my present location and do different things based on my location. I also have full control over my own browser settings (no Corporate Policies, etc). So for me, changing the chrome://flags setting does the trick.

Many of these answers mention how to share the project on Git, which is easy, you just share the code on git, but one thing to take note of is that there is no apparent "project file" that the end user can double click on. Instead you have to use Import->General->Existing project and select the whole folder

Removing and adding DOM element is slower than modification of existing one.

If your option sets have same length, you may do something like this:

$('#my-select option')
.each(function(index) {
    $(this).text('someNewText').val('someNewValue');
});

In case your new option set has different length, you may delete/add empty options you really need, using some technique described above.

Hmm... There's no need to complicate things. The basics work great always.

    $string = 'abcdef';
    $len = strlen( $string );
    $x = 0;

Forward Direction:

while ( $len > $x ) echo $string[ $x++ ];

Outputs: abcdef

Reverse Direction:

while ( $len ) echo $string[ --$len ];

Outputs: fedcba

Very easy solution with jQuery:

$('#myFormId').attr('action', 'myNewActionTarget.html');

Your form:

<form action=get_action() id="myFormId">
...
</form>

If MySQLdb's now distributed in a way that requires setuptools, your choices are either to download the latter (e.g. from here) or refactor MySQLdb's setup.py to bypass setuptools (maybe just importing setup and Extension from plain distutils instead might work, but you may also need to edit some of the setup_*.py files in the same directory).

Depending on how your site's Python installation is configured, installing extensions for your own individual use without requiring sysadm rights may be hard, but it's never truly impossible if you have shell access. You'll need to tweak your Python's sys.path to start with a directory of your own that's your personal equivalent of the system-wide site pacages directory, e.g. by setting PYTHONPATH persistently in your own environment, and then manually place in said personal directory what normal installs would normally place in site-packages (and/or subdirectories thereof).

You need to call the AddAddress function once for each E-Mail address you want to send to. There are only two arguments for this function: recipient_email_address and recipient_name. The recipient name is optional and will not be used if not present.

$mailer->AddAddress('[email protected]', 'First Name');
$mailer->AddAddress('[email protected]', 'Second Name');
$mailer->AddAddress('[email protected]', 'Third Name');

You could use an array to store the recipients and then use a for loop. I hope it helps.

In Spring, those objects that form the backbone of your application and that are managed by the Spring IoC container are referred to as beans. A bean is simply an object that is instantiated, assembled and otherwise managed by a Spring IoC container;

The following was tested for IIS 8.5 and Windows 8.1.

As of IIS 7, Windows recommends restarting IIS via net stop/start. Via the command prompt (as Administrator):

> net stop WAS
> net start W3SVC

net stop WAS will stop W3SVC as well. Then when starting, net start W3SVC will start WAS as a dependency.

You're using clearInterval incorrectly.

This is the proper use:

Set the timer with

var_name = setInterval(fontChange, 500);

and then

clearInterval(var_name);

TL;DR No, it can't be done automatically. Yes, it is possible.

import matplotlib.pyplot as plt
my_colors = plt.rcParams['axes.prop_cycle']() # <<< note that we CALL the prop_cycle
fig, axes = plt.subplots(2,3)
for ax in axes.flatten(): ax.plot((0,1), (0,1), **next(my_colors))

Each plot (axes) in a figure (figure) has its own cycle of colors — if you don't force a different color for each plot, all the plots share the same order of colors but, if we stretch a bit what "automatically" means, it can be done.

The OP wrote

[...] I have to identify each plot with a different color which should be automatically generated by [Matplotlib].

But... Matplotlib automatically generates different colors for each different curve

In [10]: import numpy as np
    ...: import matplotlib.pyplot as plt

In [11]: plt.plot((0,1), (0,1), (1,2), (1,0));
Out[11]:

So why the OP request? If we continue to read, we have

Can you please give me a method to put different colors for different plots in the same figure?

and it make sense, because each plot (each axes in Matplotlib's parlance) has its own color_cycle (or rather, in 2018, its prop_cycle) and each plot (axes) reuses the same colors in the same order.

In [12]: fig, axes = plt.subplots(2,3)

In [13]: for ax in axes.flatten():
    ...:     ax.plot((0,1), (0,1))

If this is the meaning of the original question, one possibility is to explicitly name a different color for each plot.

If the plots (as it often happens) are generated in a loop we must have an additional loop variable to override the color automatically chosen by Matplotlib.

In [14]: fig, axes = plt.subplots(2,3)

In [15]: for ax, short_color_name in zip(axes.flatten(), 'brgkyc'):
    ...:     ax.plot((0,1), (0,1), short_color_name)

Another possibility is to instantiate a cycler object

from cycler import cycler
my_cycler = cycler('color', ['k', 'r']) * cycler('linewidth', [1., 1.5, 2.])
actual_cycler = my_cycler()

fig, axes = plt.subplots(2,3)
for ax in axes.flat:
    ax.plot((0,1), (0,1), **next(actual_cycler))

Note that type(my_cycler) is cycler.Cycler but type(actual_cycler) is itertools.cycle.

All the solutions are correct, but I found it easier just write a function to implement this. like this:

template <class T1, class T2>
void ContainerInsert(T1 t1, T2 t2)
{
    t1->insert(t1->end(), t2->begin(), t2->end());
}

That way you can avoid the temporary placement like this:

ContainerInsert(vec, GetSomeVector());

Assuming you have the following database tables:

First, you need to create the @Embeddable holding the composite identifier:

@Embeddable
public class EmployeeId implements Serializable {
 
    @Column(name = "company_id")
    private Long companyId;
 
    @Column(name = "employee_number")
    private Long employeeNumber;
 
    public EmployeeId() {
    }
 
    public EmployeeId(Long companyId, Long employeeId) {
        this.companyId = companyId;
        this.employeeNumber = employeeId;
    }
 
    public Long getCompanyId() {
        return companyId;
    }
 
    public Long getEmployeeNumber() {
        return employeeNumber;
    }
 
    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof EmployeeId)) return false;
        EmployeeId that = (EmployeeId) o;
        return Objects.equals(getCompanyId(), that.getCompanyId()) &&
                Objects.equals(getEmployeeNumber(), that.getEmployeeNumber());
    }
 
    @Override
    public int hashCode() {
        return Objects.hash(getCompanyId(), getEmployeeNumber());
    }
}

With this in place, we can map the Employee entity which uses the composite identifier by annotating it with @EmbeddedId:

@Entity(name = "Employee")
@Table(name = "employee")
public class Employee {
 
    @EmbeddedId
    private EmployeeId id;
 
    private String name;
 
    public EmployeeId getId() {
        return id;
    }
 
    public void setId(EmployeeId id) {
        this.id = id;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
}

The Phone entity which has a @ManyToOne association to Employee, needs to reference the composite identifier from the parent class via two @JoinColumnmappings:

@Entity(name = "Phone")
@Table(name = "phone")
public class Phone {
 
    @Id
    @Column(name = "`number`")
    private String number;
 
    @ManyToOne
    @JoinColumns({
        @JoinColumn(
            name = "company_id",
            referencedColumnName = "company_id"),
        @JoinColumn(
            name = "employee_number",
            referencedColumnName = "employee_number")
    })
    private Employee employee;
 
    public Employee getEmployee() {
        return employee;
    }
 
    public void setEmployee(Employee employee) {
        this.employee = employee;
    }
 
    public String getNumber() {
        return number;
    }
 
    public void setNumber(String number) {
        this.number = number;
    }
}

Here's my one liner for positive integers, based on this answer:

usage:

(-7).Mod(3); // returns 2

implementation:

static int Mod(this int a, int n) => (((a %= n) < 0) ? n : 0) + a;

Sadly, this is not possible by default to use section as another user suggested, since a section is only available to the immediate child of a View.

What works however is implementing and redefining the section in every view, meaning:

section Head
{
    @RenderSection("Head", false)
}

This way every view can implement a head section, not just the immediate children. This only works partly though, especially with multiple partials the troubles begin (as you have mentioned in your question).

So the only real solution to your problem is using the ViewBag. The best would probably be a seperate collection (list) for CSS and scripts. For this to work, you need to ensure that the List used is initialized before any of the views are executed. Then you can can do things like this in the top of every view/partial (without caring if the Scripts or Styles value is null:

ViewBag.Scripts.Add("myscript.js");
ViewBag.Styles.Add("mystyle.css");

In the layout you can then loop through the collections and add the styles based on the values in the List.

@foreach (var script in ViewBag.Scripts)
{
    <script type="text/javascript" src="@script"></script>
}
@foreach (var style in ViewBag.Styles)
{
    <link href="@style" rel="stylesheet" type="text/css" />
}

I think it's ugly, but it's the only thing that works.

******UPDATE**** Since it starts executing the inner views first and working its way out to the layout and CSS styles are cascading, it would probably make sense to reverse the style list via ViewBag.Styles.Reverse().

This way the most outer style is added first, which is inline with how CSS style sheets work anyway.

This HTML code depends on the simpledrag vanilla JavaScript lightweight library (less than 60 lines of code).

The way I have done it is to have the actionLink and the image seperately. Set the actionlink image as hidden and then added a jQuery trigger call. This is more of a workaround.

'<%= Html.ActionLink("Button Name", "Index", null, new { @class="yourclassname" }) %>'
<img id="yourImage" src="myImage.jpg" />

Trigger example:

$("#yourImage").click(function () {
  $('.yourclassname').trigger('click');
});

The application could not be verified" , in your device there could be already an app installed with the same bundle identifier.

So Simple solution Just delete the App & try again.. ....

This can happen in more than one scenario, below is a list of well known scenarios :

// calling empty on a function 
empty(myFunction($myVariable)); // the return value of myFunction should be saved into a variable
// then you can use empty on your variable

// using parenthesis to access an element of an array, parenthesis are used to call a function

if (isset($_POST('sms_code') == TRUE ) { ...
// that should be if(isset($_POST['sms_code']) == TRUE)

This also could be triggered when we try to increment the result of a function like below:

$myCounter = '356';

$myCounter = intVal($myCounter)++; // we try to increment the result of the intVal...
// like the first case, the ++ needs to be called on a variable, a variable should hold the the return of the function then we can call ++ operator on it.

First go to Resource View (from menu: View --> Other Window --> Resource View). Then in Resource View navigate through resources, if any. If there is already a resource of Icon type, added by Visual Studio, then open and edit it. Otherwise right-click and select Add Resource, and then add a new icon.

Use the embedded image editor in order to edit the existing or new icon. Note that an icon can include several types (sizes), selected from Image menu.

Then compile your project and see the effect.

Simplest way to do in Python 2.5 exactly what you ask about:

import itertools as it

... it.izip(it.count(1), xrange(2000, 2005)) ...

If you want a list, as you appear to, use zip in lieu of it.izip.

(BTW, as a general rule, the best way to make a list out of a generator or any other iterable X is not [x for x in X], but rather list(X)).

Josh is correct but he left out one variation:

ALTER ROLE <role_name> IN DATABASE <db_name> SET search_path TO schema1,schema2;

Set the search path for the user, in one particular database.

On my blog, the reason of this error is a plugin named Broken Link checker. This plugin has high resource usage from hosting, resulting in this error.

Check if a plugin on your installation is behaving similarly like this.

As previously mentioned, this issue can be seen if you have multiple files with the same name, but in different groups (yellow folders) in the project navigator. In my case, this was intentional as I had multiple subdirectories each with a "preview.jpg" that I wanted copying to the app bundle:

In this situation, you need to ensure that Xcode recognises the directory reference (blue folder icon), not just the groups.

Remove the offending files and choose "Remove Reference" (so we don't delete them entirely):

Re-add them to the project by dragging them back into the project navigator. In the dialog that appears, choose "Create folder references for any added folders":

Notice that the files now have a blue folder icon in the project navigator:

If you now look under the "Copy Bundle Resources" section of the target's build phases, you will notice that there is a single entry for the entire folder, rather than entries for each item contained within the directory. The compiler will not complain about multiple build commands for those files.

I get this problem from time to time, and when I do, I have been able to solve it by using a backup of the database folder(s) that give the problem.

When you check your 'Event Viewer > Windows Log > Application', if you see an error:

InnoDB: Attempted to open a previously opened tablespace. Previous tablespace [database]/[table] uses space ID: 59 at filepath: .\[database]\[table].ibd. Cannot open tablespace [different db]/[different table] which uses space ID: 59 at filepath: .\[different db]/[different table].ibd

Then what works for me, is delete the first mentioned [database] folder in your MySQL data directory, and copy the backup of that database folder to where it was previously.

Then start MySQL, and it starts again for me, without this 1067 error.

This is a shorthand Ajax function, which is equivalent to:

$.ajax({  type: "POST",
           url: url,  
          data: { username: value_login.val(), firstname: value_firstname.val(), 
                  lastname: value_lastname.val(), email: value_email.val(),
                  password: value_password.val()
                },
          dataType: "json"
       success: success// -> call your func here  
      });

Hope This helps

No need to compile stuff. You can do the same with ssh-keygen:

ssh-keygen -f pub1key.pub -i

will read the public key in openssl format from pub1key.pub and output it in OpenSSH format.

Note: In some cases you will need to specify the input format:

ssh-keygen -f pub1key.pub -i -mPKCS8

From the ssh-keygen docs (From man ssh-keygen):

-m key_format Specify a key format for the -i (import) or -e (export) conversion options. The supported key formats are: “RFC4716” (RFC 4716/SSH2 public or private key), “PKCS8” (PEM PKCS8 public key) or “PEM” (PEM public key). The default conversion format is “RFC4716”.

EDIT:

Forgot to say that this solution is in pure js, the only thing you need is a browser that supports promises https://developer.mozilla.org/it/docs/Web/JavaScript/Reference/Global_Objects/Promise

For those who still needs to accomplish such, I've written my own solution that combines promises with timeouts.

Code:

/*
    class: Geolocalizer
        - Handles location triangulation and calculations.
        -- Returns various prototypes to fetch position from strings or coords or dragons or whatever.
*/

var Geolocalizer = function () {
    this.queue          = [];     // queue handler..
    this.resolved       = [];
    this.geolocalizer = new google.maps.Geocoder();  
};

Geolocalizer.prototype = {
    /*
        @fn: Localize
        @scope: resolve single or multiple queued requests.
        @params: <array> needles
        @returns: <deferred> object
    */
    Localize: function ( needles ) {
        var that = this;
        // Enqueue the needles.
        for ( var i = 0; i < needles.length; i++ ) {
            this.queue.push(needles[i]);
        }
        // return a promise and resolve it after every element have been fetched (either with success or failure), then reset the queue.
        return new Promise (
            function (resolve, reject) {
                that.resolveQueueElements().then(function(resolved){
                  resolve(resolved);
                  that.queue    = [];
                  that.resolved = [];
                });
            }
        );
    },

    /*
        @fn: resolveQueueElements
        @scope: resolve queue elements.
        @returns: <deferred> object (promise)
    */

    resolveQueueElements: function (callback) {
        var that = this;
        return new Promise(
            function(resolve, reject) {
                // Loop the queue and resolve each element.
                // Prevent QUERY_LIMIT by delaying actions by one second.
                (function loopWithDelay(such, queue, i){
                    console.log("Attempting the resolution of " +queue[i-1]);
                    setTimeout(function(){
                        such.find(queue[i-1], function(res){
                           such.resolved.push(res); 
                        });
                        if (--i) {
                            loopWithDelay(such,queue,i);
                        }
                    }, 1000);
                })(that, that.queue, that.queue.length);

                // Check every second if the queue has been cleared.
                var it = setInterval(function(){
                    if (that.queue.length == that.resolved.length) {
                        resolve(that.resolved);
                        clearInterval(it);
                    }
                }, 1000);
            }
        );
    },

    /*
        @fn: find
        @scope: resolve an address from string
        @params: <string> s, <fn> Callback
    */
    find: function (s, callback) {
        this.geolocalizer.geocode({
            "address": s
        }, function(res, status){
           if (status == google.maps.GeocoderStatus.OK) {
               var r = {
                   originalString:  s,
                   lat: res[0].geometry.location.lat(),
                   lng: res[0].geometry.location.lng()
               };
               callback(r);
           }
            else {
                callback(undefined);
                console.log(status);
                console.log("could not locate " + s);
            }
        });
    }
};

Please note that it's just a part of a bigger library I wrote to handle google maps stuff, hence comments may be confusing.

Usage is quite simple, the approach, however, is slightly different: instead of looping and resolving one address at a time, you will need to pass an array of addresses to the class and it will handle the search by itself, returning a promise which, when resolved, returns an array containing all the resolved (and unresolved) address.

Example:

var myAmazingGeo = new Geolocalizer();
var locations = ["Italy","California","Dragons are thugs...","China","Georgia"];
myAmazingGeo.Localize(locations).then(function(res){ 
   console.log(res); 
});

Console output:

Attempting the resolution of Georgia
Attempting the resolution of China
Attempting the resolution of Dragons are thugs...
Attempting the resolution of California
ZERO_RESULTS
could not locate Dragons are thugs...
Attempting the resolution of Italy

Object returned:

The whole magic happens here:

(function loopWithDelay(such, queue, i){
                    console.log("Attempting the resolution of " +queue[i-1]);
                    setTimeout(function(){
                        such.find(queue[i-1], function(res){
                           such.resolved.push(res); 
                        });
                        if (--i) {
                            loopWithDelay(such,queue,i);
                    }
                }, 750);
            })(that, that.queue, that.queue.length);

Basically, it loops every item with a delay of 750 milliseconds between each of them, hence every 750 milliseconds an address is controlled.

I've made some further testings and I've found out that even at 700 milliseconds I was sometimes getting the QUERY_LIMIT error, while with 750 I haven't had any issue at all.

In any case, feel free to edit the 750 above if you feel you are safe by handling a lower delay.

Hope this helps someone in the near future ;)

Did you try this?

[DataType(DataType.Date)]

Another simple option that updates on a click of the checkbox.

HTML:

<input type="checkbox" id="checkbox/>
<input disabled type="submit" id="item"/>

jQuery:

$('#checkbox').click(function() {
    if (this.checked) {
        $('#item').prop('disabled', false); // If checked enable item       
    } else {
        $('#item').prop('disabled', true); // If checked disable item                   
    }
});

You could do it with a bool. I've been learning recently and found I could do it this way. In this example, I'm checking a user's input to the console:

using System;
using System.Linq;

namespace CheckStringContent
{
    class Program
    {
        static void Main(string[] args)
        {
            //Get a password to check
            Console.WriteLine("Please input a Password: ");
            string userPassword = Console.ReadLine();

            //Check the string
            bool symbolCheck = userPassword.Any(p => !char.IsLetterOrDigit(p));

            //Write results to console
            Console.WriteLine($"Symbols are present: {symbolCheck}");     
        }
    }
}

This returns 'True' if special chars (symbolCheck) are present in the string, and 'False' if not present.

You have two ways:

First go to the particular path of Android SDK:

1) Open your command prompt and traverse to the platform-tools directory through it such as

$ cd Frameworks\Android-Sdk\platform-tools

2) Run your adb commands now such as to know that your adb is working properly :

$ adb devices OR adb logcat OR simply adb

Second way is :

1) Right click on your My Computer.

2) Open Environment variables.

3) Add new variable to your System PATH variable(Add if not exist otherwise no need to add new variable if already exist).

4) Add path of platform-tools directory to as value of this variable such as C:\Program Files\android-sdk\platform-tools.

5) Restart your computer once.

6) Now run the above adb commands such adb devices or other adb commands from anywhere in command prompt.

Also on you can fire a command on terminal setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools"

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

W3C doc says regarding "border-radius" property: "supported in IE9+, Firefox, Chrome, Safari, and Opera".

Hence I assume you're testing on IE8 or below.

For "regular elements" there is a solution compatible with IE8 & other old/poor browsers. See below.

HTML:

<div class="myWickedClass">
  <span class="myCoolItem">Some text</span> <span class="myCoolItem">Some text</span> <span class="myCoolItem"> Some text</span> <span class="myCoolItem">Some text</span>
</div>

CSS:

.myWickedClass{
  padding: 0 5px 0 0;
  background: #F7D358 url(../img/roundedCorner_right.png) top right no-repeat scroll;
  -moz-border-radius: 10px;
  -webkit-border-radius: 10px;
  border-radius: 10px;
  font: normal 11px Verdana, Helvetica, sans-serif;
  color: #A4A4A4;
}
.myWickedClass > .myCoolItem:first-child {
  padding-left: 6px;
  background: #F7D358 url(../img/roundedCorner_left.png) 0px 0px no-repeat scroll;
}
.myWickedClass > .myCoolItem {
  padding-right: 5px;
}

You need to create both roundedCorner_right.png & roundedCorner_left.png. These are work around for IE8 (& below) to fake the rounded corner feature.

So in this example above we apply the left rounded corner to the first span element in the containing div, & we apply the right rounded corner to the containing div. These images overlap the browser-provided "squary corners" & give the illusion of being part of a rounded element.

The idea for inputs would be to do the same logic. However, input is an empty element, " element is empty, it contains attributes only", in other word, you cannot wrap a span into an input such as <input><span class="myCoolItem"></span></input> to then use background images like in the previous example.

Hence the solution seems to be to do the opposite: wrap the input into another element. see this answer rounded corners of input elements in IE

If you are using Godaddy certificate, then the issue is that the machine on which the certificate request is created and the machine on which is you are trying to complete the request are different. So do the following:

1. Use the "generated-private-key.txt" file that was created the godaddy. Use this file to create .pfx certificate(with private key) you can use OpenSSL command:

   openssl pkcs12 -export -out {mydomain}.pfx -inkey generated-private-key.txt -in {your .crt file}

2. The above command will generate certificate with private key {mydomain}.pfx.

3. Import this certificate in IIS using "Import" option

You can just pass a Date object:
For current date:

$('#calendar').fullCalendar({
    defaultDate: new Date()
});

For specific date '2016-05-20':

$('#calendar').fullCalendar({
    defaultDate: new Date(2016, 4, 20)
});

I know this is old, but since Postgresql 9.3 there is an option to use a keyword "LATERAL" to use RELATED subqueries inside of JOINS, so the query from the question would look like:

SELECT 
    name, author_id, count(*), t.total
FROM
    names as n1
    INNER JOIN LATERAL (
        SELECT 
            count(*) as total
        FROM 
            names as n2
        WHERE 
            n2.id = n1.id
            AND n2.author_id = n1.author_id
    ) as t ON 1=1
GROUP BY 
    n1.name, n1.author_id

Try the following code to display scroll bar always on your page,

::-webkit-scrollbar {
  -webkit-appearance: none;
  width: 10px;
}

::-webkit-scrollbar-thumb {
  border-radius: 5px;
  background-color: rgba(0,0,0,.5);
  -webkit-box-shadow: 0 0 1px rgba(255,255,255,.5);
}

this will always show the vertical and horizontal scroll bar on your page. If you need only a vertical scroll bar then put overflow-x: hidden

There is also:

try:
    del mydict[key]
except KeyError:
    pass

This only does 1 lookup instead of 2. However, except clauses are expensive, so if you end up hitting the except clause frequently, this will probably be less efficient than what you already have.

You could have your controller action take an object which would reflect the form input names and the default model binder will automatically create this object for you:

[HttpPost]
public ActionResult SubmitAction(SomeModel model)
{
    var value1 = model.SimpleProp1;
    var value2 = model.SimpleProp2;
    var value3 = model.ComplexProp1.SimpleProp1;
    ...

    ... return something ...
}

Another (obviously uglier) way is:

[HttpPost]
public ActionResult SubmitAction()
{
    var value1 = Request["SimpleProp1"];
    var value2 = Request["SimpleProp2"];
    var value3 = Request["ComplexProp1.SimpleProp1"];
    ...

    ... return something ...
}

The pseudo-elements generated by ::before and ::after are contained by the element's formatting box, and thus don't apply to replaced elements such as img, or to br elements.

If you are using NumPy arrays, shape can be used. For example

  >>> a = numpy.array([[[1,2,3],[1,2,3]],[[12,3,4],[2,1,3]]])
  >>> a
  array([[[ 1,  2,  3],
         [ 1,  2,  3]],

         [[12,  3,  4],
         [ 2,  1,  3]]])
 >>> a.shape
 (2, 2, 3)

If you want to fix vbs associations type

regsvr32 vbscript.dll
regsvr32 jscript.dll
regsvr32 wshext.dll
regsvr32 wshom.ocx
regsvr32 wshcon.dll
regsvr32 scrrun.dll

Also if you can't use vbs due to management then convert your script to a vb.net program which is designed to be easy, is easy, and takes 5 minutes.

Big difference is functions and subs are both called using brackets rather than just functions.

So the compilers are installed on all computers with .NET installed.

See this article here on how to make a .NET exe. Note the sample is for a scripting host. You can't use this, you have to put your vbs code in as .NET code.

How can I convert a VBScript to an executable (EXE) file?
