The correct answer is already stated (just use SortedDictionary).

However, if by chance you have some need to retain your collection as Dictionary, it is possible to access the Dictionary keys in an ordered way, by, for example, ordering the keys in a List, then using this list to access the Dictionary. An example...

Dictionary<string, int> dupcheck = new Dictionary<string, int>();

...some code that fills in "dupcheck", then...

if (dupcheck.Count > 0) {
  Console.WriteLine("\ndupcheck (count: {0})\n----", dupcheck.Count);
  var keys_sorted = dupcheck.Keys.ToList();
    keys_sorted.Sort();
  foreach (var k in keys_sorted) {
    Console.WriteLine("{0} = {1}", k, dupcheck[k]);
  }
}

Don't forget using System.Linq; for this.

For content editable stuff (not regular inputs, you need to use selectNodeContents (rather than just selectNode).

NOTE: All the references to "document.selection" and "createTextRange()" are for IE 8 and lower... You'll not likely need to support that monster if you're attempting to do tricky stuff like this.

function selectElemText(elem) {

    //Create a range (a range is a like the selection but invisible)
    var range = document.createRange();

    // Select the entire contents of the element
    range.selectNodeContents(elem);

    // Don't select, just positioning caret:
    // In front 
    // range.collapse();
    // Behind:
    // range.collapse(false);

    // Get the selection object
    var selection = window.getSelection();

    // Remove any current selections
    selection.removeAllRanges();

    // Make the range you have just created the visible selection
    selection.addRange(range);

}

Late to the party admittedly, how about this which will make your host operating system keys available to root inside the container, on the fly:

docker run -v ~/.ssh:/mnt -it my_image /bin/bash -c "ln -s /mnt /root/.ssh; ssh [email protected]"

I'm not in favour of using Dockerfile to install keys since iterations of your container may leave private keys behind.

There is a more simpler way using the mongoose exists function

router.post("/groups/members", async (ctx) => {
    const group_name = ctx.request.body.group_membership.group_name;
    const member_name = ctx.request.body.group_membership.group_members;
    const GroupMembership = GroupModels.GroupsMembers;
    console.log("group_name : ", group_name, "member : ", member_name);
    try {
        if (
            (await GroupMembership.exists({
                "group_membership.group_name": group_name,
            })) === false
        ) {
            console.log("new function");
            const newGroupMembership = await GroupMembership.insertMany({
                group_membership: [
                    { group_name: group_name, group_members: [member_name] },
                ],
            });
            await newGroupMembership.save();
        } else {
            const UpdateGroupMembership = await GroupMembership.updateOne(
                { "group_membership.group_name": group_name },
                { $push: { "group_membership.$.group_members": member_name } },
            );
            console.log("update function");
            await UpdateGroupMembership.save();
        }
        ctx.response.status = 201;
        ctx.response.message = "A member added to group successfully";
    } catch (error) {
        ctx.body = {
            message: "Some validations failed for Group Member Creation",
            error: error.message,
        };
        console.log(error);
        ctx.throw(400, error);
    }
});

For int64_t type:

#include <inttypes.h>
int64_t t;
printf("%" PRId64 "\n", t);

for uint64_t type:

#include <inttypes.h>
uint64_t t;
printf("%" PRIu64 "\n", t);

you can also use PRIx64 to print in hexadecimal.

cppreference.com has a full listing of available macros for all types including intptr_t (PRIxPTR). There are separate macros for scanf, like SCNd64.

A typical definition of PRIu16 would be "hu", so implicit string-constant concatenation happens at compile time.

For your code to be fully portable, you must use PRId32 and so on for printing int32_t, and "%d" or similar for printing int.

Cookie-Based Authentication

Cookies based Authentication works normally in these 4 steps-

1. The user provides a username and password in the login form and clicks Log In.
2. After the request is made, the server validate the user on the backend by querying in the database. If the request is valid, it will create a session by using the user information fetched from the database and store them, for each session a unique id called session Id is created ,by default session Id is will be given to client through the Browser.

3. Browser will submit this session Id on each subsequent requests, the session ID is verified against the database, based on this session id website will identify the session belonging to which client and then give access the request.

4. Once a user logs out of the app, the session is destroyed both client-side and server-side.

The fully-qualified name is opbtained as follows:

String fqn = YourClass.class.getName();

But you need to read a classpath resource. So use

InputStream in = YourClass.getResourceAsStream("resource.txt");

I came here for a reminder of how to set up the query but the existing examples were hard to follow. Here is an example with more explanation.

SQLiteDatabase db = helper.getReadableDatabase();

String table = "table2";
String[] columns = {"column1", "column3"};
String selection = "column3 =?";
String[] selectionArgs = {"apple"};
String groupBy = null;
String having = null;
String orderBy = "column3 DESC";
String limit = "10";

Cursor cursor = db.query(table, columns, selection, selectionArgs, groupBy, having, orderBy, limit);

Parameters

• table: the name of the table you want to query
• columns: the column names that you want returned. Don't return data that you don't need.
• selection: the row data that you want returned from the columns (This is the WHERE clause.)
• selectionArgs: This is substituted for the ? in the selection String above.
• groupBy and having: This groups duplicate data in a column with data having certain conditions. Any unneeded parameters can be set to null.
• orderBy: sort the data
• limit: limit the number of results to return

This code will help you, and it's fairly self-explanatory:

#include <stdio.h>      /* Standard Library of Input and Output */
#include <complex.h>    /* Standard Library of Complex Numbers */

int main() {

    double complex z1 = 1.0 + 3.0 * I;
    double complex z2 = 1.0 - 4.0 * I;

    printf("Working with complex numbers:\n\v");

    printf("Starting values: Z1 = %.2f + %.2fi\tZ2 = %.2f %+.2fi\n", creal(z1), cimag(z1), creal(z2), cimag(z2));

    double complex sum = z1 + z2;
    printf("The sum: Z1 + Z2 = %.2f %+.2fi\n", creal(sum), cimag(sum));

    double complex difference = z1 - z2;
    printf("The difference: Z1 - Z2 = %.2f %+.2fi\n", creal(difference), cimag(difference));

    double complex product = z1 * z2;
    printf("The product: Z1 x Z2 = %.2f %+.2fi\n", creal(product), cimag(product));

    double complex quotient = z1 / z2;
    printf("The quotient: Z1 / Z2 = %.2f %+.2fi\n", creal(quotient), cimag(quotient));

    double complex conjugate = conj(z1);
    printf("The conjugate of Z1 = %.2f %+.2fi\n", creal(conjugate), cimag(conjugate));

    return 0;
}

  with:

creal(z1): get the real part (for float crealf(z1), for long double creall(z1))

cimag(z1): get the imaginary part (for float cimagf(z1), for long double cimagl(z1))

Another important point to remember when working with complex numbers is that functions like cos(), exp() and sqrt() must be replaced with their complex forms, e.g. ccos(), cexp(), csqrt().

As of Xcode 8, you can define class properties in Obj-C. This has been added to interoperate with Swift's static properties.

Objective-C now supports class properties, which interoperate with Swift type properties. They are declared as: @property (class) NSString *someStringProperty;. They are never synthesized. (23891898)

Here is an example

@interface YourClass : NSObject

@property (class, nonatomic, assign) NSInteger currentId;

@end

@implementation YourClass

static NSInteger _currentId = 0;

+ (NSInteger)currentId {
    return _currentId;
}

+ (void)setCurrentId:(NSInteger)newValue {
    _currentId = newValue;
}

@end

Then you can access it like this:

YourClass.currentId = 1;
val = YourClass.currentId;

Here is a very interesting explanatory post I used as a reference to edit this old answer.

2011 Answer: (don't use this, it's terrible)

If you really really don't want to declare a global variable, there another option, maybe not very orthodox :-), but works... You can declare a "get&set" method like this, with an static variable inside:

+ (NSString*)testHolder:(NSString*)_test {
    static NSString *test;

    if(_test != nil) {
        if(test != nil)
            [test release];
        test = [_test retain];
    }

    // if(test == nil)
    //     test = @"Initialize the var here if you need to";

    return test;
}

So, if you need to get the value, just call:

NSString *testVal = [MyClass testHolder:nil]

And then, when you want to set it:

[MyClass testHolder:testVal]

In the case you want to be able to set this pseudo-static-var to nil, you can declare testHolder as this:

+ (NSString*)testHolderSet:(BOOL)shouldSet newValue:(NSString*)_test {
    static NSString *test;

    if(shouldSet) {
        if(test != nil)
            [test release];
        test = [_test retain];
    }

    return test;
}

And two handy methods:

+ (NSString*)test {
    return [MyClass testHolderSet:NO newValue:nil];
}

+ (void)setTest:(NSString*)_test {
    [MyClass testHolderSet:YES newValue:_test];
}

Hope it helps! Good luck.

I believe it's just a convention for things that are boolean. A bit like saying "IsValid".

When you say you are Forking a repository you are basically creating a copy of the repository under your GitHub ID. The main point to note here is that any changes made to the original repository will be reflected back to your forked repositories(you need to fetch and rebase). However, if you make any changes to your forked repository you will have to explicitly create a pull request to the original repository. If your pull request is approved by the administrator of the original repository, then your changes will be committed/merged with the existing original code-base. Until then, your changes will be reflected only in the copy you forked.

In short:

The Fork & Pull Model lets anyone fork an existing repository and push changes to their personal fork without requiring access be granted to the source repository. The changes must then be pulled into the source repository by the project maintainer.

Note that after forking you can clone your repository (the one under your name) locally on your machine. Make changes in it and push it to your forked repository. However, to reflect your changes in the original repository your pull request must be approved.

Couple of other interesting dicussions -

Are git forks actually git clones?

How do I update a GitHub forked repository?

Try adding an event listener for clicks:

document.getElementById('button').addEventListener("click", function() {
   alert("You clicked me");
}?);?

Using addEventListener is probably a better idea then setting onclick - onclick can easily be overwritten by another piece of code.

You can use a variable to store whether or not the button has been clicked before:

var clicked = false
document.getElementById('button').addEventListener("click", function() {
   clicked = true
}?);?

addEventListener on MDN

Console.WriteLine(string.Join<TYPE>("\n", someObjectList));

Try sudo npm uninstall cordova -g to uninstall it globally and then just npm install cordova without the -g flag after cding to the local app directory

If the mouse over for all over the component is your option, you can directly is @hostListener to handle the events to perform the mouse over al below.

  import {HostListener} from '@angular/core';

  @HostListener('mouseenter') onMouseEnter() {
    this.hover = true;
    this.elementRef.nativeElement.addClass = 'edit';
  }

  @HostListener('mouseleave') onMouseLeave() {
    this.hover = false;
    this.elementRef.nativeElement.addClass = 'un-edit';
  }

Its available in @angular/core. I tested it in angular 4.x.x

Apparently it does not and I didn't quite expect it would. HOWEVER Ivan brings up a good possibility that has escaped Android people.

What is the purpose of an emulator? to EMULATE, right? I don't see why for testing purposes -provided the tester understands the limitations- the emulator might not add a Wifi emulator.

It could for example emulate WiFi access by using the underlying internet connection of the host. Obviously testing WPA/WEP differencess would not make sense but at least it could toggle access via WiFi.

Or some sort of emulator plugin where there would be a base WiFi emulator that would emulate WiFi access via the underlying connection but then via configuration it could emulate WPA/WEP by providing a list of fake WiFi networks and their corresponding fake passwords that would be matched against a configurable list of credentials.

After all the idea is to do initial testing on the emulator and then move on to the actual device.

I use a combination of json.get() and instanceof to read in values that might be either integers or integer strings.

These three test cases illustrate:

int val;
Object obj;
JSONObject json = new JSONObject();
json.put("number", 1);
json.put("string", "10");
json.put("other", "tree");

obj = json.get("number");
val = (obj instanceof Integer) ? (int) obj : (int) Integer.parseInt((String) obj);
System.out.println(val);

obj = json.get("string");
val = (obj instanceof Integer) ? (int) obj : (int) Integer.parseInt((String) obj);
System.out.println(val);

try {
    obj = json.get("other");
    val = (obj instanceof Integer) ? (int) obj : (int) Integer.parseInt((String) obj);
} catch (Exception e) {
    // throws exception
}

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

This the simplest way to assign an async arrow function expression to a named variable:

const foo = async () => {
  // do something
}

_{(Note that this is not strictly equivalent to async function foo() { }. Besides the differences between the function keyword and an arrow expression, the function in this answer is not "hoisted to the top".)}

len(repr(float(x)/3))

However I must say that this isn't as reliable as you think.

Floats are entered/displayed as decimal numbers, but your computer (in fact, your standard C library) stores them as binary. You get some side effects from this transition:

>>> print len(repr(0.1))
19
>>> print repr(0.1)
0.10000000000000001

The explanation on why this happens is in this chapter of the python tutorial.

A solution would be to use a type that specifically tracks decimal numbers, like python's decimal.Decimal:

>>> print len(str(decimal.Decimal('0.1')))
3

speaking from computation and memory bound point of view (scientific computing) 4000 threads will make application run really slow. Part of the problem is a very high overhead of context switching and most likely very poor memory locality.

But it also depends on your architecture. From where I heard Niagara processors are suppose to be able to handle multiple threads on a single core using some kind of advanced pipelining technique. However I have no experience with those processors.

Your variable energies probably has the wrong shape:

>>> from numpy import array
>>> set([1,2,3]) & set(range(2, 10))
set([2, 3])
>>> set(array([1,2,3])) & set(range(2,10))
set([2, 3])
>>> set(array([[1,2,3],])) & set(range(2,10))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'numpy.ndarray'

And that's what happens if you read columnar data using your approach:

>>> data
array([[  1.,   2.,   3.],
       [  3.,   4.,   5.],
       [  5.,   6.,   7.],
       [  8.,   9.,  10.]])
>>> hsplit(data,3)[0]
array([[ 1.],
       [ 3.],
       [ 5.],
       [ 8.]])

Probably you can simply use

>>> data[:,0]
array([ 1.,  3.,  5.,  8.])

instead.

(P.S. Your code looks like it's undecided about whether it's data or elementdata. I've assumed it's simply a typo.)

With procrun you need to copy prunsrv to the application directory (download), and create an install.bat like this:

set PR_PATH=%CD%
SET PR_SERVICE_NAME=MyService
SET PR_JAR=MyService.jar
SET START_CLASS=org.my.Main
SET START_METHOD=main
SET STOP_CLASS=java.lang.System
SET STOP_METHOD=exit
rem ; separated values
SET STOP_PARAMS=0
rem ; separated values
SET JVM_OPTIONS=-Dapp.home=%PR_PATH%
prunsrv.exe //IS//%PR_SERVICE_NAME% --Install="%PR_PATH%\prunsrv.exe" --Jvm=auto --Startup=auto --StartMode=jvm --StartClass=%START_CLASS% --StartMethod=%START_METHOD% --StopMode=jvm --StopClass=%STOP_CLASS% --StopMethod=%STOP_METHOD% ++StopParams=%STOP_PARAMS% --Classpath="%PR_PATH%\%PR_JAR%" --DisplayName="%PR_SERVICE_NAME%" ++JvmOptions=%JVM_OPTIONS%

I presume to

• run this from the same directory where the jar and prunsrv.exe is
• the jar has its working MANIFEST.MF
• and you have shutdown hooks registered into JVM (for example with context.registerShutdownHook() in Spring)...
• not using relative paths for files outside the jar (for example log4j should be used with log4j.appender.X.File=${app.home}/logs/my.log or something alike)

Check the procrun manual and this tutorial for more information.

If you are stuck with a machine where you don't have root access, then it is better to deal with a custom Python installation.

The Anaconda installation worked like a charm:

• Installing packages (SciPy.org)
• Anaconda Python/R Distribution - download

After installation,

[bash]$ /xxx/devTools/python/anaconda/bin/pip list --format=columns | grep numpy

numpy 1.13.3 numpydoc 0.7.0

In Visual Studio 2012 I had the same error. Had to uninstall NuGet (Tools > Extensions and Updates > Installed > All: NuGet Package Manager: Uninstall button). Then closed Visual Studio. Then reopened Visual Studio and reinstalled NuGet (Tools > Extensions and Updates > Online > Visual Studio Gallery: NuGet Package Manager: Download button). Then in following windows: click Install button, then click close button. Then close and reopen Visual Studio.

It's incorrect, but you can try this instead:

select
    a.x,
    ( select b.y from b where b.v = a.v) as by,
    ( select b.z from b where b.v = a.v) as bz
from a

you can also use subquery in join

 select
        a.x,
        b.y,
        b.z
    from a
    left join (select y,z from b where ... ) b on b.v = a.v

or

   select
        a.x,
        b.y,
        b.z
    from a
    left join b on b.v = a.v

If you want to preserve the details come with ls like file size etc in your output then this should work.

sed "s|<OLDPATH>|<NEWPATH>|g" input_file > output_file

What ended up finally working for me was to add the remote repository name to the git fetch command, like this:

git fetch core

Now you can see all of them like this:

git branch --all

This worked for me:

  INSERT INTO [TABLE]
  VALUES ('text','''test.com''', 1)

Basically, you take the single quote you want to insert and replace it with two. So if you want to insert a string of text ('text') and add single quotes around it, it would be ('''text'''). Hope this helps.

I added the control to the Triggers tag in the update panel:

    </ContentTemplate>
    <Triggers>
        <asp:PostBackTrigger ControlID="exportLinkButton" />
    </Triggers>
</asp:UpdatePanel>

This way the exportLinkButton will trigger the UpdatePanel to update.
More info here.

In new code assignment should be,

B[0] = 5

In func(B), you are just passing address of the pointer which is pointing to array B. You can do change in func() as B[i] or *(B + i). Where i is the index of the array.

In the first code the declaration says,

int *B[10]

says that B is an array of 10 elements, each element of which is a pointer to a int. That is, B[i] is a int pointer and *B[i] is the integer it points to the first integer of the i-th saved text line.

Range.Rows and Range.Columns return essentially the same Range except for the fact that the new Range has a flag which indicates that it represents Rows or Columns. This is necessary for some Excel properties such as Range.Count and Range.Hidden and for some methods such as Range.AutoFit():

• Range.Rows.Count returns the number of rows in Range.
• Range.Columns.Count returns the number of columns in Range.
• Range.Rows.AutoFit() autofits the rows in Range.
• Range.Columns.AutoFit() autofits the columns in Range.

You might find that Range.EntireRow and Range.EntireColumn are useful, although they still are not exactly what you are looking for. They return all possible columns for EntireRow and all possible rows for EntireColumn for the represented range.

I know this because SpreadsheetGear for .NET comes with .NET APIs which are very similar to Excel's APIs. The SpreadsheetGear API comes with several strongly typed overloads to the IRange indexer including the one you probably wish Excel had:

• IRange this[int row1, int column1, int row2, int column2];

Use this function:

var getCleanUrl = function(url) {_x000D_
  return url.replace(/#.*$/, '').replace(/\?.*$/, '');_x000D_
};_x000D_
_x000D_
// get rid of hash and params_x000D_
console.log(getCleanUrl('https://sidanmor.com/?firstname=idan&lastname=mor'));

If you want all the href parts, use this:

var url = document.createElement('a');_x000D_
url.href = 'https://developer.mozilla.org/en-US/search?q=URL#search-results-close-container';_x000D_
_x000D_
console.log(url.href); // https://developer.mozilla.org/en-US/search?q=URL#search-results-close-container_x000D_
console.log(url.protocol); // https:_x000D_
console.log(url.host); // developer.mozilla.org_x000D_
console.log(url.hostname); // developer.mozilla.org_x000D_
console.log(url.port); // (blank - https assumes port 443)_x000D_
console.log(url.pathname); // /en-US/search_x000D_
console.log(url.search); // ?q=URL_x000D_
console.log(url.hash); // #search-results-close-container_x000D_
console.log(url.origin); // https://developer.mozilla.org

The Python documentation does cover this:

class Singleton(object):
    def __new__(cls, *args, **kwds):
        it = cls.__dict__.get("__it__")
        if it is not None:
            return it
        cls.__it__ = it = object.__new__(cls)
        it.init(*args, **kwds)
        return it
    def init(self, *args, **kwds):
        pass

I would probably rewrite it to look more like this:

class Singleton(object):
    """Use to create a singleton"""
    def __new__(cls, *args, **kwds):
        """
        >>> s = Singleton()
        >>> p = Singleton()
        >>> id(s) == id(p)
        True
        """
        self = "__self__"
        if not hasattr(cls, self):
            instance = object.__new__(cls)
            instance.init(*args, **kwds)
            setattr(cls, self, instance)
        return getattr(cls, self)

    def init(self, *args, **kwds):
        pass

It should be relatively clean to extend this:

class Bus(Singleton):
    def init(self, label=None, *args, **kwds):
        self.label = label
        self.channels = [Channel("system"), Channel("app")]
        ...

I had this problem and the issue was that I had the package loaded in another R instance. Simply closing all R instances and installing on a fresh instance allowed for the package to be installed.

Generally, you can also install if every remaining instance has never loaded the package as well (even if it installed an old version).

You can execute it just as you select a table using SELECT clause. In addition you can provide parameters within parentheses.

Try with below syntax:

SELECT * FROM yourFunctionName(parameter1, parameter2)

If that's all what you want to do, you don't need to convert it into an array. You can just access it as:

string myData=yourDataTable.Rows[0][1].ToString();//Gives you USA

So here is a solution for both your requests in the manner you originally asked for. It will give human readability filesize without the filesize limits everyone is experiencing.

To be able to use this batch file conveniently put it in your SendTo folder. This will allow you to right click a folder or selection of folders, click on the SendTo option, and then select this batch file.

To find the SendTo folder on your computer simplest way is to open up cmd then copy in this line as is.

Hey seems like you run in to reference issues when you're trying to copy an object then deleting a property. Somewhere you have to assign primitive variables so javascript makes a new value.

Simple trick (may be horrendous) I used was this

var obj = {"key1":"value1","key2":"value2","key3":"value3"};

// assign it as a new variable for javascript to cache
var copy = JSON.stringify(obj);
// reconstitute as an object
copy = JSON.parse(copy);
// now you can safely run delete on the copy with completely new values
delete copy.key2

console.log(obj)
// output: {key1: "value1", key2: "value2", key3: "value3"}
console.log(copy)
// output: {key1: "value1", key3: "value3"}

To convert your object in JSON with Jackson:

ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json = ow.writeValueAsString(object);

You can authenticate and log the user in as stated here: https://docs.djangoproject.com/en/dev/topics/auth/default/#how-to-log-a-user-in

This will give you access to the User object from which you can get the username and then do a HttpResponseRedirect to the custom URL.

"[1-9][0-9]*|0"

I'd just use "[0-9]+" to represent positive whole numbers.

None of the answers quite fitted the specific case if you're looked to know if a specfic activity is in the forground and if you're an SDK without direct access to the Application. For me I was in background thread having just recieved a push notification for a new chat message and only want to display a system notification if the chat screen isn't in the foreground.

Using the ActivityLifecycleCallbacks that as been recommended in other answers I've created a small util class that houses the logic to whether MyActivity is in the Foreground or not.

class MyActivityMonitor(context: Context) : Application.ActivityLifecycleCallbacks {

private var isMyActivityInForeground = false

init {
    (context.applicationContext as Application).registerActivityLifecycleCallbacks(this)
}

fun isMyActivityForeground() = isMyActivityInForeground

override fun onActivityPaused(activity: Activity?) {
    if (activity is MyActivity) {
        isMyActivityInForeground = false
    }
}

override fun onActivityResumed(activity: Activity?) {
    if (activity is MyActivity) {
        isMyActivityInForeground = true
    }
}

}

Remove maven dependenices from build path

A good alternative is this:

find . -type f | xargs chmod -v 644

and for directories:

find . -type d | xargs chmod -v 755

and to be more explicit:

find . -type f | xargs -I{} chmod -v 644 {}

this will also work, if you like

 xcopy  C:\Test\Log "c:\Test\Backup-%date:~4,2%-%date:~7,2%-%date:~10,4%_%time:~0,2%%time:~3,2%" /s /i
 del C:\Test\Log

UPDATE myTable

Try this https://ngrok.com/docs#expose

Just run ngrok 3000 , 3000 is the port number you want to expose to the internet. You can insert the port number which you want to expose, for rails its 3000. This will tunnel your localhost to the internet and you will be able to view your local host from anywhere

A very good reason for using IDEs is that they are the accepted way of producing modern software. If you do not use one, then you likely use "old fashioned" stuff like vi and emacs. This can lead people to conclude - possibly wrongly - that you are stuck in your ways and unable to adapt to new ways of working. In an industry such as software development - where ideas can be out of date in mere months - this is a dangerous state to get into. It could seriously damage your future job prospects...

For Twitter Bootstrap 3:

You must change the CSS transition as specified in the other answer:

.carousel-inner > .item {
    position: relative;
    display: none;
    -webkit-transition: 0.6s ease-in-out left;
    -moz-transition: 0.6s ease-in-out left;
    -o-transition: 0.6s ease-in-out left;
    transition: 0.6s ease-in-out left;
}

From 0.6 seconds to 1.5 seconds (for example).

But also, there is some Javascript to change. In the bootstrap.js there is a line:

.emulateTransitionEnd(600)

This should be changed to the corresponding amount of milliseconds. So for 1.5 seconds you would change the number to 1500:

.emulateTransitionEnd(1500)

I would strongly recommend not to use synchronous (blocking) functions, as they hold other concurrent operations. Instead, use asynchronous fs.promises:

const fs = require('fs').promises

const setValue = (fn, value) => 
  fs.readFile(fn)
    .then(body => JSON.parse(body))
    .then(json => {
      // manipulate your data here
      json.value = value
      return json
    })
    .then(json => JSON.stringify(json))
    .then(body => fs.writeFile(fn, body))
    .catch(error => console.warn(error))

Remeber that setValue returns a pending promise, you'll need to use .then function or, within async functions, the await operator.

// await operator
await setValue('temp.json', 1)           // save "value": 1
await setValue('temp.json', 2)           // then "value": 2
await setValue('temp.json', 3)           // then "value": 3

// then-sequence
setValue('temp.json', 1)                 // save "value": 1
  .then(() => setValue('temp.json', 2))  // then save "value": 2
  .then(() => setValue('temp.json', 3))  // then save "value": 3

<table style="border:2px solid #ddedde">
    <tr>
        <td style="border:2px solid #ddedde;width:50%">a</td>
        <td style="border:2px solid #ddedde;width:20%">b</td>
        <td style="border:2px solid #ddedde;width:30%">c</td>
    </tr>
    <tr>
        <td style="border:2px solid #ddedde;width:50%">a</td>
        <td style="border:2px solid #ddedde;width:20%">b</td>
        <td style="border:2px solid #ddedde;width:30%">c</td>
    </tr>
</table>

However, you should also read Elias Mårtenson's answer on Android plurals treatment of “zero”. There is a problem with the interpretation of certain values such as "zero".

Best easy way with JAVA 8 is for English Alphabetic sort

Class Implementation

public class NewspaperClass implements Comparable<NewspaperClass>{
   public String name;

   @Override
   public int compareTo(NewspaperClass another) {
      return name.compareTo(another.name);
   }
}

Sort

  Collections.sort(Your List);

If you want to sort for alphabet that contains non English characters you can use Locale... Below code use Turkish character sort...

Class Implementation

public class NewspaperClass implements Comparator<NewspaperClass> {
   public String name;
   public Boolean isUserNewspaper=false;
   private Collator trCollator = Collator.getInstance(new Locale("tr_TR"));



   @Override
   public int compare(NewspaperClass lhs, NewspaperClass rhs) {
      trCollator.setStrength(Collator.PRIMARY);
      return trCollator.compare(lhs.name,rhs.name);
   }
}

Sort

Collections.sort(your array list,new NewspaperClass());

You can add a new Primary Key column to an existing table, which can have sequence numbers, using command:

ALTER TABLE mydb.mytable ADD pk_columnName INT IDENTITY 

This worked for me:

git remote set-url heroku <repo git>

This replacement old url heroku.

You can check with:

git remote -v

Make a HTML Table from a JSON array of Objects by extending $ as shown below

$.makeTable = function (mydata) {
            var table = $('<table border=1>');
            var tblHeader = "<tr>";
            for (var k in mydata[0]) tblHeader += "<th>" + k + "</th>";
            tblHeader += "</tr>";
            $(tblHeader).appendTo(table);
            $.each(mydata, function (index, value) {
                var TableRow = "<tr>";
                $.each(value, function (key, val) {
                    TableRow += "<td>" + val + "</td>";
                });
                TableRow += "</tr>";
                $(table).append(TableRow);
            });
            return ($(table));
        };

and use as follows:

var mydata = eval(jdata);
var table = $.makeTable(mydata);
$(table).appendTo("#TableCont");

where TableCont is some div

In addition to Sophie's answer, I also have found a use in sending in child component types, doing something like this:

var ListView = React.createClass({
    render: function() {
        var items = this.props.data.map(function(item) {
            return this.props.delegate({data:item});
        }.bind(this));
        return <ul>{items}</ul>;
    }
});

var ItemDelegate = React.createClass({
    render: function() {
        return <li>{this.props.data}</li>
    }
});

var Wrapper = React.createClass({    
    render: function() {
        return <ListView delegate={ItemDelegate} data={someListOfData} />
    }
});

In XSLT 1.0 the upper-case() and lower-case() functions are not available. If you're using a 1.0 stylesheet the common method of case conversion is translate():

<xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'" />
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />


<xsl:template match="/">
  <xsl:value-of select="translate(doc, $lowercase, $uppercase)" />
</xsl:template>

Ctrl+K,Ctrl+R opens the Object Browser in Visual Studio 2010. Find what you're looking for by searching and browsing and filtering the results. See also Ctrl+Alt+J. ^K ^R is better because it puts your caret right in the search box, ready to type your new search, even when the Object Browser is already open.

Set the Browse list on the top left to where you want to look to get started. From there you can use the search box (2nd text box from the top, goes all the way across the Object Browser window) or you can just go through everything from the tree on the left. Searches are temporary but the "selected components" set by the Browse list persists. Set a custom set with the little "..." button just to the right of the list.

Objects, packages, namespaces, types, etc. on the left; fields, methods, constants, etc. on the top right, docstrings on the lower right.

The display mode of a pane can be changed by right-clicking in the empty space of the window; tree organized by assembly/container or by namespace and other preferences.

Items can be right-clicked to find, copy and filter.

For keyboard navigation, use Ctrl+K,Ctrl+R from anywhere to start a new search, Enter to execute the search you just typed or pasted and Ctrl+F6 to make the Object Browser close. ALT+<-- to go back and ALT+--> to go forward through the search history. More can be set; search for "ObjectBrowser" in the keyboard shortcut config.

If the key shortcuts above don't work, Object Browser should be in the View menu somewhere with a different shortcut. If all else fails, search for "ObjectBrowser" under Tools->Options->Environment->Keyboard->"Show commands containing".

General ternary syntax:

value_true if <test> else value_false

Another way can be:

[value_false, value_true][<test>]

e.g:

count = [0,N+1][count==N]

This evaluates both branches before choosing one. To only evaluate the chosen branch:

[lambda: value_false, lambda: value_true][<test>]()

e.g.:

count = [lambda:0, lambda:N+1][count==N]()

Add this to .classpath file ..

Yes you can change it. but in api 22 and above, using NotificationCompat.Builder and setColorized(true) :

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, context.getPackageName())
                .setContentTitle(title)
                .setContentText(message)
                .setSmallIcon(icon, level)
                .setLargeIcon(largeIcon)
                .setContentIntent(intent)
                .setColorized(true)
                .setDefaults(0)
                .setCategory(Notification.CATEGORY_SERVICE)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setPriority(NotificationCompat.PRIORITY_HIGH);

Pass a duration to show() and hide():

When a duration is provided, .show() becomes an animation method.

E.g. element.delay(1000).show(0)

Try to execute the procedure like this,

To avoid to add sources files .java to your package you should do

cd src/
jar cvf mylib.jar com/**/*.class

Supposed that your project structure was like

myproject/
    src/
      com/
        mycompany/
          mainClass.java
          mainClass.class

Based on the code I've used for finding multiple instances of a string within a larger string, your code would look like:

List<int> inst = new List<int>();
int index = 0;
while (index >=0)
{
    index = source.IndexOf("extract\"(me,i-have lots. of]punctuation", index);
    inst.Add(index);
    index++;
}

Specifically, the MySQLi extension provides the following extremely useful benefits over the old MySQL extension..

OOP Interface (in addition to procedural) Prepared Statement Support Transaction + Stored Procedure Support Nicer Syntax Speed Improvements Enhanced Debugging

PDO Extension

PHP Data Objects extension is a Database Abstraction Layer. Specifically, this is not a MySQL interface, as it provides drivers for many database engines (of course including MYSQL).

PDO aims to provide a consistent API that means when a database engine is changed, the code changes to reflect this should be minimal. When using PDO, your code will normally "just work" across many database engines, simply by changing the driver you're using.

In addition to being cross-database compatible, PDO also supports prepared statements, stored procedures and more, whilst using the MySQL Driver.

It was probably discussed, but as of CSS3 there is nothing like what you need (see also "Is there a CSS selector for elements containing certain text?"). You will have to use additional markup, like this:

<li><span class="foo">some text</span></li>
<li>some other text</li>

Then refer to it the usual way:

li > span.foo {...}

That would be the ALL_DIRECTORIES view:

http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/statviews_1075.htm#i1576965

try this way Simply loop through that, building your own array. This code assumes it's an array of strings, it shouldn't be hard to modify to suit your particular array structure.

JSONArray jsonArray = new JSONArray(jsonArrayString);
List<String> list = new ArrayList<String>();
for (int i=0; i<jsonArray.length(); i++) {
    list.add( jsonArray.getString(i) );

Our server calls stored procs from Java like so - works on both SQL Server 2000 & 2008:

String SPsql = "EXEC <sp_name> ?,?";   // for stored proc taking 2 parameters
Connection con = SmartPoolFactory.getConnection();   // java.sql.Connection
PreparedStatement ps = con.prepareStatement(SPsql);
ps.setEscapeProcessing(true);
ps.setQueryTimeout(<timeout value>);
ps.setString(1, <param1>);
ps.setString(2, <param2>);
ResultSet rs = ps.executeQuery();

To uninstall an .egg you need to rm -rf the egg (it might be a directory) and remove the matching line from site-packages/easy-install.pth

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

Change this line:

The 2 should be 0. Every count starts at 0.

//Aboutme.Text = String.Format("{2}", reader.GetString(0));//wrong

//Aboutme.Text = String.Format("{0}", reader.GetString(0));//correct

The #import directive was added to Objective-C as an improved version of #include. Whether or not it's improved, however, is still a matter of debate. #import ensures that a file is only ever included once so that you never have a problem with recursive includes. However, most decent header files protect themselves against this anyway, so it's not really that much of a benefit.

Basically, it's up to you to decide which you want to use. I tend to #import headers for Objective-C things (like class definitions and such) and #include standard C stuff that I need. For example, one of my source files might look like this:

#import <Foundation/Foundation.h>

#include <asl.h>
#include <mach/mach.h>

A colleague asked me how to open A LOT of ssh sessions at once. I used cobbal's answer to write this script:

tmpdir=$( mktemp -d )
trap '$DEBUG rm -rf $tmpdir ' EXIT
index=1

{
cat <<COMMANDS
ssh user1@host1
ssh user2@host2
COMMANDS
} | while read command
do 
  COMMAND_FILE=$tmpdir/$index.command
  index=$(( index + 1 ))
  echo $command > $COMMAND_FILE
  chmod +x  $COMMAND_FILE
  open $COMMAND_FILE
done
sleep 60

By updating the list of commands ( they don't have to be ssh invocations ), you will get an additional open window for every command executed. The sleep 60 at the end is there to keep the .command files around while they are being executed. Otherwise, the shell completes too quickly, executing the trap to delete the temp directory ( created by mktemp ) before the launched sessions have an opportunity to read the files.

When you want to direct download any image or pdf file from browser instead on opening it in new tab then in javascript you should set value to download attribute of create dynamic link

    var path= "your file path will be here"; 
    var save = document.createElement('a');  
    save.href = filePath; 
    save.download = "Your file name here"; 
    save.target = '_blank'; 
    var event = document.createEvent('Event');
    event.initEvent('click', true, true); 
    save.dispatchEvent(event);
   (window.URL || window.webkitURL).revokeObjectURL(save.href);

For new Chrome update some time event is not working. for that following code will be use

  var path= "your file path will be here"; 
    var save = document.createElement('a');  
    save.href = filePath; 
    save.download = "Your file name here"; 
    save.target = '_blank'; 
    document.body.appendChild(save);
    save.click();
    document.body.removeChild(save);

Appending child and removing child is useful for Firefox, Internet explorer browser only. On chrome it will work without appending and removing child

Octave is basically an open source version of MATLAB. It was written to be just that. MATLAB has a very nice GUI which makes it a bit easier to use but the next stable release of OCTAVE will also have a GUI, which I have tested in the unstable release, and looks fantastic. Octave is much more buggy because it was developed and maintained by a group of volunteers, where the development of MATLAB is funded by millions of dollars by industry. I'm still a student and am using a student version of MATLAB, but I am thinking of going over to Octave once the stable version with the GUI is released.

MATLAB is probably a lot more powerful than Octave, and the algorithms run faster, but for most applications, Octave is more than adequate and is, in my opinion' an amazing tool that is completely free, where Octave is completely free.

I would say use MATLAB while you can use the academic version, but the switch to Octave should be seamless as they use the exact same syntax.

Lastly, there is the issue of SIMULINK. If you want to do simulation or control system design (there are probably a million other uses) SIMULINK is fantastic and comes with MATLAB. I don't think any other comes close to this, although Scilab is apparently a 'good' open source alternative, I haven't tried it.

Peace.

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

This should give you what you want. You will definitely want x items divided by y items per page, the problem is when uneven numbers come up, so if there is a partial page we also want to add one page.

int x = number_of_items;
int y = items_per_page;

// with out library
int pages = x/y + (x % y > 0 ? 1 : 0)

// with library
int pages = (int)Math.Ceiling((double)x / (double)y);

Slightly slower alternative, just for the records:

x <- c(12.45,34,4,0,-234,45.6,4)
max( x[x!=max(x)] )
min( x[x!=min(x)] )

Objective C includes a built-in way to detect a the encoding of a string embedded in NSData.

NSData* data = // Assign your NSData object...

NSString* string;
NSStringEncoding encoding = [NSString stringEncodingForData:data encodingOptions:nil convertedString:&string usedLossyConversion:nil];

To rotate by 45 degrees in IE, you need the following code in your stylesheet:

filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(SizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476)"; /* IE8 */

You’ll note from the above that IE8 has different syntax to IE6/7. You need to supply both lines of code if you want to support all versions of IE.

The horrible numbers there are in Radians; you’ll need to work out the figures for yourself if you want to use an angle other than 45 degrees (there are tutorials on the internet if you look for them).

Also note that the IE6/7 syntax causes problems for other browsers due to the unescaped colon symbol in the filter string, meaning that it is invalid CSS. In my tests, this causes Firefox to ignore all CSS code after the filter. This is something you need to be aware of as it can cause hours of confusion if you get caught out by it. I solved this by having the IE-specific stuff in a separate stylesheet which other browsers didn’t load.

All other current browsers (including IE9 and IE10 — yay!) support the CSS3 transform style (albeit often with vendor prefixes), so you can use the following code to achieve the same effect in all other browsers:

-moz-transform: rotate(45deg);  /* FF3.5/3.6 */
-o-transform: rotate(45deg);  /* Opera 10.5 */
-webkit-transform: rotate(45deg);  /* Saf3.1+ */
transform: rotate(45deg);  /* Newer browsers (incl IE9) */

Hope that helps.

Edit

Since this answer is still getting up-votes, I feel I should update it with information about a JavaScript library called CSS Sandpaper that allows you to use (near) standard CSS code for rotations even in older IE versions.

Once you’ve added CSS Sandpaper to your site, you should then be able to write the following CSS code for IE6–8:

-sand-transform: rotate(40deg);

Much easier than the traditional filter style you'd normally need to use in IE.

Edit

Also note an additional quirk specifically with IE9 (and only IE9), which supports both the standard transform and the old style IE -ms-filter. If you have both of them specified, this can result in IE9 getting completely confused and rendering just a solid black box where the element would have been. The best solution to this is to avoid the filter style by using the Sandpaper polyfill mentioned above.

We can also use -

$('#x').prop('scrollHeight') <!-- Height -->
$('#x').prop('scrollWidth')  <!-- Width -->

I do not think any of these answers are flexible enough for a large enterprise level application. I'm not a fan of overusing the ViewBag, but in this case, for flexibility, I'd make an exception. Here's what I'd do...

You should have a base controller on all of your controllers. Add your Layout data OnActionExecuting in your base controller (or OnActionExecuted if you want to defer that)...

public class BaseController : Controller
{
    protected override void OnActionExecuting(ActionExecutingContext     
        filterContext)
    {
        ViewBag.LayoutViewModel = MyLayoutViewModel;
    }
}

public class HomeController : BaseController
{
    public ActionResult Index()
    {
        return View(homeModel);
    }
}

Then in your _Layout.cshtml pull your ViewModel from the ViewBag...

@{
  LayoutViewModel model = (LayoutViewModel)ViewBag.LayoutViewModel;
}

<h1>@model.Title</h1>

Or...

<h1>@ViewBag.LayoutViewModel.Title</h1>

Doing this doesn't interfere with the coding for your page's controllers or view models.

The ES6 way of require is import. You can export your class and import it somewhere else using import { ClassName } from 'path/to/ClassName'syntax.

import fs from 'fs';
export default class Animal {

  constructor(name){
    this.name = name ;
  }

  print(){
    console.log('Name is :'+ this.name);
  }
}

import Animal from 'path/to/Animal.js';

This will work for generating a number 1 - 10. Make sure you import Random at the top of your code.

import java.util.Random;

If you want to test it out try something like this.

Random rn = new Random();

for(int i =0; i < 100; i++)
{
    int answer = rn.nextInt(10) + 1;
    System.out.println(answer);
}

Also if you change the number in parenthesis it will create a random number from 0 to that number -1 (unless you add one of course like you have then it will be from 1 to the number you've entered).

You have a few typos in your select. It should be: input:not([disabled]):not([type="submit"]):focus

See this jsFiddle for a proof of concept. On a sidenote, if I removed the "background-color" property, then the box shadow no longer works. Not sure why.

A map() creates an array, so a return is expected for all code paths (if/elses).

If you don't want an array or to return data, use forEach instead.

WORKING ALWAYS ON TOP IMAGE BUTTON

first of all sorry for my english

i edit your codes and make working image button that listens his touch event do not give touch control to his background elements.

also it gives touch listeners to out of other elements

button alingments are bottom and left

you can chage alingments but you need to chages cordinats in touch event in the if element

Your code is indeed using the normal way to create and delete a dynamic object. Yes, it's perfectly normal (and indeed guaranteed by the language standard!) that delete will call the object's destructor, just like new has to invoke the constructor.

If you weren't instantiating Object1 directly but some subclass thereof, I'd remind you that any class intended to be inherited from must have a virtual destructor (so that the correct subclass's destructor can be invoked in cases analogous to this one) -- but if your sample code is indeed representative of your actual code, this cannot be your current problem -- must be something else, maybe in the destructor code you're not showing us, or some heap-corruption in the code you're not showing within that function or the ones it calls...?

BTW, if you're always going to delete the object just before you exit the function which instantiates it, there's no point in making that object dynamic -- just declare it as a local (storage class auto, as is the default) variable of said function!

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is)

You can execute a subshell and redirect all output while still putting the process in the background:

( ./script.sh blah > ~/log/blah.log 2>&1 ) &
echo $! > ~/pids/blah.pid

Had the same problem. Solved as given below. Use command :

sudo tail -f /var/log/messages|grep -i mysql

to check if SELinux policy is causing the issue. If so, first check if SELinux policy is enabled using command #sestatus. If it shows enabled, then disable it. To disable:

1. # vi /etc/sysconfig/selinux
2. change 'SELINUX=enforcing' to 'SELINUX=disabled'
3. restart linux
4. check with sestatus and it should show "disabled"

Uninstall and reinstall mysql. It should be working.

The easiest way to ask a UITextView is just calling -sizeToFitit should work also with scrollingEnabled = YES, after that check for the height and add a height constraint on the text view with the same value.
Pay attention that UITexView contains insets, this means that you can't ask the string object how much space it want to use, because this is just the bounding rect of the text.
All the person that are experiencing wrong size using -sizeToFit it's probably due to the fact that the text view has not been layout yet to the interface size.
This always happen when you use size classes and a UITableView, the first time cells are created in the - tableView:cellForRowAtIndexPath: the comes out with the size of the any-any configuration, if you compute you value just now the text view will have a different width than the expected and this will screw all sizes.
To overcome this issue I've found useful to override the -layoutSubviews method of the cell to recalculate textview height.

What I did was: Added/Updated the following code:

framework: 'jasmine',
jasmineNodeOpts: 
{
    // Jasmine default timeout
    defaultTimeoutInterval: 60000,
    expectationResultHandler(passed, assertion) 
    {
      // do something
    },
}

This works:

function getBreakText($t) {
    return strtr($t, array('\\r\\n' => '<br>', '\\r' => '<br>', '\\n' => '<br>'));
}

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

From IEEE floating-point exceptions in C++ :

This page will answer the following questions.

• My program just printed out 1.#IND or 1.#INF (on Windows) or nan or inf (on Linux). What happened?
• How can I tell if a number is really a number and not a NaN or an infinity?
• How can I find out more details at runtime about kinds of NaNs and infinities?
• Do you have any sample code to show how this works?
• Where can I learn more?

These questions have to do with floating point exceptions. If you get some strange non-numeric output where you're expecting a number, you've either exceeded the finite limits of floating point arithmetic or you've asked for some result that is undefined. To keep things simple, I'll stick to working with the double floating point type. Similar remarks hold for float types.

Debugging 1.#IND, 1.#INF, nan, and inf

If your operation would generate a larger positive number than could be stored in a double, the operation will return 1.#INF on Windows or inf on Linux. Similarly your code will return -1.#INF or -inf if the result would be a negative number too large to store in a double. Dividing a positive number by zero produces a positive infinity and dividing a negative number by zero produces a negative infinity. Example code at the end of this page will demonstrate some operations that produce infinities.

Some operations don't make mathematical sense, such as taking the square root of a negative number. (Yes, this operation makes sense in the context of complex numbers, but a double represents a real number and so there is no double to represent the result.) The same is true for logarithms of negative numbers. Both sqrt(-1.0) and log(-1.0) would return a NaN, the generic term for a "number" that is "not a number". Windows displays a NaN as -1.#IND ("IND" for "indeterminate") while Linux displays nan. Other operations that would return a NaN include 0/0, 0*8, and 8/8. See the sample code below for examples.

In short, if you get 1.#INF or inf, look for overflow or division by zero. If you get 1.#IND or nan, look for illegal operations. Maybe you simply have a bug. If it's more subtle and you have something that is difficult to compute, see Avoiding Overflow, Underflow, and Loss of Precision. That article gives tricks for computing results that have intermediate steps overflow if computed directly.

After calling GroupBy, you get a series of groups IEnumerable<Grouping>, where each Grouping itself exposes the Key used to create the group and also is an IEnumerable<T> of whatever items are in your original data set. You just have to call Count() on that Grouping to get the subtotal.

foreach(var line in data.GroupBy(info => info.metric)
                        .Select(group => new { 
                             Metric = group.Key, 
                             Count = group.Count() 
                        })
                        .OrderBy(x => x.Metric))
{
     Console.WriteLine("{0} {1}", line.Metric, line.Count);
}

I'm assuming you already have a list/array of some class that looks like

class UserInfo {
    string name;
    int metric;
    ..etc..
} 
...
List<UserInfo> data = ..... ;

When you do data.GroupBy(x => x.metric), it means "for each element x in the IEnumerable defined by data, calculate it's .metric, then group all the elements with the same metric into a Grouping and return an IEnumerable of all the resulting groups. Given your example data set of

    <DATA>           | Grouping Key (x=>x.metric) |
joe  1 01/01/2011 5  | 1
jane 0 01/02/2011 9  | 0
john 2 01/03/2011 0  | 2
jim  3 01/04/2011 1  | 3
jean 1 01/05/2011 3  | 1
jill 2 01/06/2011 5  | 2
jeb  0 01/07/2011 3  | 0
jenn 0 01/08/2011 7  | 0

it would result in the following result after the groupby:

(Group 1): [joe  1 01/01/2011 5, jean 1 01/05/2011 3]
(Group 0): [jane 0 01/02/2011 9, jeb  0 01/07/2011 3, jenn 0 01/08/2011 7]
(Group 2): [john 2 01/03/2011 0, jill 2 01/06/2011 5]
(Group 3): [jim  3 01/04/2011 1]

Change data type of DataFrame column:

          success: function(response) { alert(response); },

When the realm changes, the browser may show another popup window if it doesn't have credentials for that particular realm.

For whatever reason, I noticed that setting to unicode for "All Configurations" did not actually apply to all configurations.

Picture:

To confirm this, I would open the .vcxproj and confirm the correct token is in all 4 locations. In this photo, I am using unicode. So the string I am looking for is "Unicode". For you, you likely want it to say "MultiByte".

Picture:

If you want a true/false value, use this:

  $("input:radio[name=theme]").is(":checked")

• Have you tried following the rule with !important?
• Which stylesheet does FireBug show having last control over the element?
• Is this live somewhere to be viewed by others?

Update

I'm fairly confident that providing code-examples would help you receive a solution must faster. If you can upload an example of this issue somewhere, or provide the markup so we can test it on our localhosts, you'll have a better chance of getting some valuable input.

The problem with questions is that they lead others to believe the person asking the question has sufficient knowledge to ask the question. In programming that isn't always the case. There may have been something you missed, or accidentally jipped. Without others having eyes on your code, they have to assume you missed nothing, and overlooked nothing.

The problem is two-fold.

First, once a Modal object is instantiated, it is persistently attached to the element specified by data-target and subsequent calls to show that modal will only call toggle() on it, but will not update the values in the options. So, even though the href attributes are different on your different links, when the modal is toggled, the value for remote is not getting updated. For most options, one can get around this by directly editing the object. For instance:

$('#myModal').data('bs.modal').options.remote = "http://website.com/item/7";

However, that won't work in this case, because...

Second, the Modal plugin is designed to load the remote resource in the constructor of the Modal object, which unfortunately means that even if a change is made to the options.remote, it will never be reloaded.

A simple remedy is to destroy the Modal object before subsequent toggles. One option is to just destroy it after it finishes hiding:

$('body').on('hidden.bs.modal', '.modal', function () {
  $(this).removeData('bs.modal');
});

_{Note: Adjust the selectors as needed. This is the most general.}

Plunker

Or you could try coming up with a more complicated scheme to do something like check whether the link launching the modal is different from the previous one. If it is, destroy; if it isn't, then no need to reload.

You can either use a module like Math::Round:

use Math::Round;
my $rounded = round( $float );

Or you can do it the crude way:

my $rounded = sprintf "%.0f", $float;

If the process is a child process and $BASHPID is not set, it is possible to query the ppid of a created child process of the running process. It might be a bit ugly, but it works. Example:

sleep 1 &
mypid=$(ps -o ppid= -p "$!")

Based on Agus's function, but I prefer return just the match values:

var bob = "> bob <";
function matchAll(str, regex) {
    var res = [];
    var m;
    if (regex.global) {
        while (m = regex.exec(str)) {
            res.push(m[1]);
        }
    } else {
        if (m = regex.exec(str)) {
            res.push(m[1]);
        }
    }
    return res;
}
var Amatch = matchAll(bob, /(&.*?;)/g);
console.log(Amatch);  // yeilds: [>, <]

I saw answers that provide workaround solutions by hard coding java.exe location and x86 / x86_64 architecture string in sdk\tools\android.bat. Those are quick solutions but did not solve the fundamental issue that I am actually curious of.

The actual problem that I encountered is, the batch script is not able to find another script/jar file and thus is failed to proceed. I could say the script was poorly written.

After I made the following changes in sdk\tools\android.bat, everything works like a charm.

Specifically, I added %~dp0\:

set java_exe=
call %~dp0\lib\find_java.bat
if not defined java_exe goto :EOF

...

for /f "delims=" %%a in ('"%java_exe%" -jar %~dp0\lib\archquery.jar') do set swt_path=lib\%%a

Now, try to launch the script and SDK Manager should come out.

p.s. My installation of OS, Java 8 and Android SDK are fresh and I did not do any of the extra configuration.

p.s. You may still need to configure PATH environment variable so that the script could find the suitable java.exe.

for my case i have two localized file , ja and en

and i would like to force it to en if the preferred language in the system neither en or ja

i'm going to edit the main.m file

i 'll check whether the first preferred is en or ja , if not then i 'll change the second preferred language to en.

int main(int argc, char *argv[])
{

    [[NSUserDefaults standardUserDefaults] removeObjectForKey:@"AppleLanguages"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    NSString *lang = [[NSLocale preferredLanguages] objectAtIndex:0];

    if (![lang isEqualToString:@"en"]  &&  ![lang isEqualToString:@"ja"]){

        NSMutableArray *array = [[NSMutableArray alloc] initWithArray:[NSLocale preferredLanguages]];
        [array replaceObjectAtIndex:1 withObject:@"en"];

        [[NSUserDefaults standardUserDefaults] setObject:array forKey:@"AppleLanguages"];
        [[NSUserDefaults standardUserDefaults] synchronize];


    }

    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));


    }

or die("SQL Error line  ".__LINE__ ." class ".__CLASS__." : ".mysql_error());

mysql_close();

if(mysql_num_rows($query)===0)
{
    PERFORM ACTION;
}
else
{
    while($r=mysql_fetch_row($query))
    {
          PERFORM ACTION;
    }
}

I've found a great example using javax.websocket here:

http://www.programmingforliving.com/2013/08/jsr-356-java-api-for-websocket-client-api.html

Here the code based on the example linked above:

TestApp.java:

package testapp;

import java.net.URI;
import java.net.URISyntaxException;

public class TestApp {

    public static void main(String[] args) {
        try {
            // open websocket
            final WebsocketClientEndpoint clientEndPoint = new WebsocketClientEndpoint(new URI("wss://real.okcoin.cn:10440/websocket/okcoinapi"));

            // add listener
            clientEndPoint.addMessageHandler(new WebsocketClientEndpoint.MessageHandler() {
                public void handleMessage(String message) {
                    System.out.println(message);
                }
            });

            // send message to websocket
            clientEndPoint.sendMessage("{'event':'addChannel','channel':'ok_btccny_ticker'}");

            // wait 5 seconds for messages from websocket
            Thread.sleep(5000);

        } catch (InterruptedException ex) {
            System.err.println("InterruptedException exception: " + ex.getMessage());
        } catch (URISyntaxException ex) {

Use alter session set current_schema = <username>, in your case as an execute immediate.

See Oracle's documentation for further information.

In your case, that would probably boil down to (untested)

DECLARE

   CURSOR client_cur IS
     SELECT  distinct username 
       from all_users 
      where length(username) = 3;

   -- client cursor 
   CURSOR emails_cur IS
   SELECT id, name 
     FROM org;

BEGIN

   FOR client IN client_cur LOOP

   -- ****
      execute immediate 
     'alter session set current_schema = ' || client.username;
   -- ****

      FOR email_rec in client_cur LOOP

         dbms_output.put_line(
             'Org id is ' || email_rec.id || 
             ' org nam '  || email_rec.name);

      END LOOP;

  END LOOP;
END;
/

Another Solution

if your txt file looks like this: mouse snake cat lizard wolf dog

you could reverse this file by simply using array indexing in python '''

contents=[]
def tail(contents,n):
    with open('file.txt') as file:
        for i in file.readlines():
            contents.append(i)

    for i in contents[:n:-1]:
        print(i)

tail(contents,-5)

result: dog wolf lizard cat

Sticky footer with fixed height:

HTML scheme:

<body>
   <div id="wrap">
   </div>
   <div id="footer">
   </div>
</body>

CSS:

html, body {
    height: 100%;
}
#wrap {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto -60px;
}
#footer {
    height: 60px;
}

this type of error usually occur when you try to access data through the index in which data data has not been assign. for example

//assign of data in to array
for(int i=0; i<10; i++){
   arr[i]=i;
}
//accessing of data through array index
for(int i=10; i>=0; i--){
cout << arr[i];
}

the code will give error (vector subscript out of range) because you are accessing the arr[10] which has not been assign yet.

I have done something like this and it works like a charm.

Simple.

P.S. There is more the the object but I just posted the relevant part.

var exScript = (function (undefined) {
    function exScript() {
        this.logInfo = [];
        var that = this;
        this.logInfo.push = function(e) {
            that.logInfo[that.logInfo.length] = e;
            console.log(e);
        };
    }
})();

In simple words, dereferencing means accessing the value from a certain memory location against which that pointer is pointing.

In the service project do the following:

1. In the solution explorer double click your services .cs file. It should bring up a screen that is all gray and talks about dragging stuff from the toolbox.
2. Then right click on the gray area and select add installer. This will add an installer project file to your project.
3. Then you will have 2 components on the design view of the ProjectInstaller.cs (serviceProcessInstaller1 and serviceInstaller1). You should then setup the properties as you need such as service name and user that it should run as.

Now you need to make a setup project. The best thing to do is use the setup wizard.

1. Right click on your solution and add a new project: Add > New Project > Setup and Deployment Projects > Setup Wizard

   a. This could vary slightly for different versions of Visual Studio. b. Visual Studio 2010 it is located in: Install Templates > Other Project Types > Setup and Deployment > Visual Studio Installer

2. On the second step select "Create a Setup for a Windows Application."

3. On the 3rd step, select "Primary output from..."

4. Click through to Finish.

Next edit your installer to make sure the correct output is included.

1. Right click on the setup project in your Solution Explorer.
2. Select View > Custom Actions. (In VS2008 it might be View > Editor > Custom Actions)
3. Right-click on the Install action in the Custom Actions tree and select 'Add Custom Action...'
4. In the "Select Item in Project" dialog, select Application Folder and click OK.
5. Click OK to select "Primary output from..." option. A new node should be created.
6. Repeat steps 4 - 5 for commit, rollback and uninstall actions.

You can edit the installer output name by right clicking the Installer project in your solution and select Properties. Change the 'Output file name:' to whatever you want. By selecting the installer project as well and looking at the properties windows, you can edit the Product Name, Title, Manufacturer, etc...

Next build your installer and it will produce an MSI and a setup.exe. Choose whichever you want to use to deploy your service.

This is how I do it:

str(1).zfill(len(str(total)))

Basically zfill takes the number of leading zeros you want to add, so it's easy to take the biggest number, turn it into a string and get the length, like this:

Python 3.6.5 (default, May 11 2018, 04:00:52) 
[GCC 8.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> total = 100
>>> print(str(1).zfill(len(str(total))))
001
>>> total = 1000
>>> print(str(1).zfill(len(str(total))))
0001
>>> total = 10000
>>> print(str(1).zfill(len(str(total))))
00001
>>> 

You can do this easily by adding a Timer to your form (from the designer) and setting it's Tick-function to run your isonline-function.

There is only one correct answer to this and most systems get it wrong. Number of milliseconds since epoch, aka a 64 bit integer. Time Zone is a UI concern and has no business in the app layer or db layer. Why does your db care what time zone something is, when you know it's going to store it as a 64 bit integer then do the transformation calculations.

Strip out the extraneous bits and just treat dates as numbers up to the UI. You can use simple arithmetic operators to do queries and logic.

Maybe this can help someone.

I was using history.replace() to redirect, so when i tried to use history.goBack(), i was send to the previous page before the page i was working with. So i changed the method history.replace() to history.push() so the history could be saved and i would be able to go back.

Of these two, the first one is a type mistake: '\0' is a character, not a pointer. The compiler still accepts it because it can convert it to a pointer.

The second one "works" only by coincidence. "\0" is a string literal of two characters. If those occur in multiple places in the source file, the compiler may, but need not, make them identical.

So the proper way to write the first one is

char* array[] = { "abc", "def", NULL };

and you test for array[index]==NULL. The proper way to test for the second one is array[index][0]=='\0'; you may also drop the '\0' in the string (i.e. spell it as "") since that will already include a null byte.

Public Class Form1

    Private animatedimage As New Bitmap("C:\MyData\Search.gif")
    Private currentlyanimating As Boolean = False

    Private Sub OnFrameChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

        Me.Invalidate()

    End Sub

    Private Sub AnimateImage()

        If currentlyanimating = True Then
            ImageAnimator.Animate(animatedimage, AddressOf Me.OnFrameChanged)
            currentlyanimating = False
        End If

    End Sub

        ImageAnimator.UpdateFrames(animatedimage)
        e.Graphics.DrawImage(animatedimage, New Point((Me.Width / 4) + 40, (Me.Height / 4) + 40))

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        currentlyanimating = False
        ImageAnimator.StopAnimate(animatedimage, AddressOf Me.OnFrameChanged)
        BtnStart.Enabled = True
        BtnStop.Enabled = False

Any logic having to do with what is displayed in the view should be delegated to a helper method, as methods in the model are strictly for handling data.

Here is what you could do:

# In the helper...

def link_to_thing(text, thing)
  (thing.url?) ? link_to(text, thing_path(thing)) : link_to(text, thing.url)
end

# In the view...

<%= link_to_thing("text", @thing) %>

This works for me without throwing an exception:

package com.sandbox;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Sandbox {

    public static void main(String[] args) throws ParseException {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
        Date parsed = format.parse("20110210");
        java.sql.Date sql = new java.sql.Date(parsed.getTime());
    }


}

THIS IS A VERY SIMPLE PROBLEM

Here is the best method for solve this problem.

Step 1 : Login to your cPanel (http://website.com/cpanel OR http://cpanel.website.com).

Step 2 : SOFTWARE -> Select PHP Version

Step 3 : Change Your Current PHP version : 5.6

Step 3 : HIT 'Set as current' [ ENJOY ]

Option 1:

NSString *haystack = @"value:hello World:value";
NSString *haystackPrefix = @"value:";
NSString *haystackSuffix = @":value";
NSRange needleRange = NSMakeRange(haystackPrefix.length,
                                  haystack.length - haystackPrefix.length - haystackSuffix.length);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle); // -> "hello World"

Option 2:

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"^value:(.+?):value$" options:0 error:nil];
NSTextCheckingResult *match = [regex firstMatchInString:haystack options:NSAnchoredSearch range:NSMakeRange(0, haystack.length)];
NSRange needleRange = [match rangeAtIndex: 1];
NSString *needle = [haystack substringWithRange:needleRange];

This one might be a bit over the top for your rather trivial case though.

Option 3:

NSString *needle = [haystack componentsSeparatedByString:@":"][1];

This one creates three temporary strings and an array while splitting.

All snippets assume that what's searched for is actually contained in the string.

You can initialize the values as empty strings and fill them in later as they are found.

dictionary = {'one':'','two':''}
dictionary['one']=1
dictionary['two']=2

None of the answers here addressed all of my needs.

1. No threads for stdout (no Queues, etc, either)
2. Non-blocking as I need to check for other things going on
3. Use PIPE as I needed to do multiple things, e.g. stream output, write to a log file and return a string copy of the output.

A little background: I am using a ThreadPoolExecutor to manage a pool of threads, each launching a subprocess and running them concurrency. (In Python2.7, but this should work in newer 3.x as well). I don't want to use threads just for output gathering as I want as many available as possible for other things (a pool of 20 processes would be using 40 threads just to run; 1 for the process thread and 1 for stdout...and more if you want stderr I guess)

I'm stripping back a lot of exception and such here so this is based on code that works in production. Hopefully I didn't ruin it in the copy and paste. Also, feedback very much welcome!

import time
import fcntl
import subprocess
import time

proc = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

# Make stdout non-blocking when using read/readline
proc_stdout = proc.stdout
fl = fcntl.fcntl(proc_stdout, fcntl.F_GETFL)
fcntl.fcntl(proc_stdout, fcntl.F_SETFL, fl | os.O_NONBLOCK)

def handle_stdout(proc_stream, my_buffer, echo_streams=True, log_file=None):
    """A little inline function to handle the stdout business. """
    # fcntl makes readline non-blocking so it raises an IOError when empty
    try:
        for s in iter(proc_stream.readline, ''):   # replace '' with b'' for Python 3
            my_buffer.append(s)

            if echo_streams:
                sys.stdout.write(s)

            if log_file:
                log_file.write(s)
    except IOError:
        pass

# The main loop while subprocess is running
stdout_parts = []
while proc.poll() is None:
    handle_stdout(proc_stdout, stdout_parts)

    # ...Check for other things here...
    # For example, check a multiprocessor.Value('b') to proc.kill()

    time.sleep(0.01)

# Not sure if this is needed, but run it again just to be sure we got it all?
handle_stdout(proc_stdout, stdout_parts)

stdout_str = "".join(stdout_parts)  # Just to demo

I'm sure there is overhead being added here but it is not a concern in my case. Functionally it does what I need. The only thing I haven't solved is why this works perfectly for log messages but I see some print messages show up later and all at once.

Just iterate over the transposed of your array:

for column in array.T:
   some_function(column)

You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):

dataGridView1.Columns[1].Width = 108;  // or whatever width works well for abbrev
dataGridView1.Columns[2].Width = 
    dataGridView1.Width 
    - dataGridView1.Columns[0].Width 
    - dataGridView1.Columns[1].Width 
    - 72;  // this is an extra "margin" number of pixels

If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize event handler of the DataGridView.

I know this is an old question, however, it is useful to mention the new features in the latest version.

From Oracle 12c onwards, you could use the new Top-n Row limiting feature. No need to write a subquery, no dependency on ROWNUM.

For example, the below query would return the employees between 4th highest till 7th highest salaries in ascending order:

SQL> SELECT empno, sal
  2  FROM   emp
  3  ORDER BY sal
  4  OFFSET 4 ROWS FETCH NEXT 4 ROWS ONLY;

     EMPNO        SAL

      7934       1300
      7844       1500
      7499       1600

It also doesn't hurt to watermark your images with Photoshop or even in Lightroom 3 now. Make sure the watermark is clear and in a conspicuous place on your image. That way if it's downloaded, at least you get the advertising!

Neither is better than the other, they do exactly the same thing. However, using .encode() and .decode() is the more common way to do it. It is also compatible with Python 2.

This works for me: \newcommand{\variablename}{the text}

For eg: \newcommand\m{100}

So when you type " \m\ is my mark " in the source code,

the pdf output displays as :

100 is my mark

A built-in parameter for saving JPEGs and PNGs is optimize.

 >>> from PIL import Image
 # My image is a 200x374 jpeg that is 102kb large
 >>> foo = Image.open("path\\to\\image.jpg")
 >>> foo.size
  (200,374)
 # I downsize the image with an ANTIALIAS filter (gives the highest quality)
 >>> foo = foo.resize((160,300),Image.ANTIALIAS)
 >>> foo.save("path\\to\\save\\image_scaled.jpg",quality=95)
 # The saved downsized image size is 24.8kb
 >>> foo.save("path\\to\\save\\image_scaled_opt.jpg",optimize=True,quality=95)
 # The saved downsized image size is 22.9kb

The optimize flag will do an extra pass on the image to find a way to reduce its size as much as possible. 1.9kb might not seem like much, but over hundreds/thousands of pictures, it can add up.

Now to try and get it down to 5kb to 10 kb, you can change the quality value in the save options. Using a quality of 85 instead of 95 in this case would yield: Unoptimized: 15.1kb Optimized : 14.3kb Using a quality of 75 (default if argument is left out) would yield: Unoptimized: 11.8kb Optimized : 11.2kb

I prefer quality 85 with optimize because the quality isn't affected much, and the file size is much smaller.

I'm assuming what you want to do is run a command without an interface (possibly automatically?). On windows there are a number of options for what you are looking for:

• Best: write your program as a windows service. These will start when no one logs into the server. They let you select the user account (which can be different than your own) and they will restart if they fail. These run all the time so you can automate tasks at specific times or on a regular schedule from within them. For more information on how to write a windows service you can read a tutorial online such as (http://msdn.microsoft.com/en-us/library/zt39148a(v=vs.110).aspx).

• Better: Start the command and hide the window. Assuming the command is a DOS command you can use a VB or C# script for this. See here for more information. An example is:

  Set objShell = WScript.CreateObject("WScript.Shell")
  objShell.Run("C:\yourbatch.bat"), 0, True
  

  You are still going to have to start the command manually or write a task to start the command. This is one of the biggest down falls of this strategy.

• Worst: Start the command using the startup folder. This runs when a user logs into the computer

Hope that helps some!

My personal opinion is that you should avoid using JSP/ASP/PHP/etc pages. Instead output to an API similar to SAX (only designed for calling rather than handling). That way there is a single layer that has to create well formed output.

As mysql official documentation:

Starting with version 6.7, Connector/Net will no longer include the MySQL for Visual Studio integration. That functionality is now available in a separate product called MySQL for Visual Studio available using the MySQL Installer for Windows (see http://dev.mysql.com/tech-resources/articles/mysql-installer-for-windows.html).

You could use jQuery and an Ajax call to post the specific update back to your server with Javascript.

It would look something like this:

function updatePostID(val, comment)
{

    var args = {};
    args.PostID = val;
    args.Comment = comment;

    $.ajax({
     type: "POST",
     url: controllerActionMethodUrlHere,
     contentType: "application/json; charset=utf-8",
     data: args,
     dataType: "json",
     success: function(msg) 
     {
        // Something afterwards here

     }
    });

}

I just ran over this one and I found by accident that CLOBs can be used in a like query:

   UPDATE IMS_TEST 
   SET TEST_Category  = 'just testing'  
 WHERE TEST_SCRIPT    LIKE '%something%'
   AND ID             = '10000239' 

This worked also for CLOBs greater than 4K

The Performance won't be great but that was no problem in my case.

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

.wrapper {_x000D_

  flex-direction: row;_x000D_
  align-items: stretch;_x000D_

}

<div class="wrapper">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_

NOTE: The previous answers here aren't particularly useful if the BLOB is an arbitrary sequence of bytes; e.g. BINARY(16) to store 128-bit GUID or md5 checksum.

In that case, there currently is no editor preference -- though I have submitted a feature request now -- see that request for more detailed explanation.

[Until/unless that feature request is implemented], the solution is HEX function in a query: SELECT HEX(mybinarycolumn) FROM mytable.

An alternative is to use phpMyAdmin instead of MySQL Workbench - there hex is shown by default.

If you are on Linux, you just need to fill the OpenCV_DIR variable with the path of opencv (containing the OpenCVConfig.cmake file)

export OpenCV_DIR=<path_of_opencv>

As of Django 1.10, the patterns module has been removed (it had been deprecated since 1.8).

Luckily, it should be a simple edit to remove the offending code, since the urlpatterns should now be stored in a plain-old list:

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    # ... your url patterns
]

There is really quite a number of ways to do this and all of the above are in one way or another valid approaches... Let me add a straightforward proposition. So assuming your current existing json file looks is this....

{
     "name":"myname"
}

And you want to bring in this new json content (adding key "id")

{
     "id": "134",
     "name": "myname"
 }

My approach has always been to keep the code extremely readable with easily traceable logic. So first, we read the entire existing json file into memory, assuming you are very well aware of your json's existing key(s).

import json 

# first, get the absolute path to json file
PATH_TO_JSON = 'data.json' #  assuming same directory (but you can work your magic here with os.)

# read existing json to memory. you do this to preserve whatever existing data. 
with open(PATH_TO_JSON,'r') as jsonfile:
    json_content = json.load(jsonfile) # this is now in memory! you can use it outside 'open'

Next, we use the 'with open()' syntax again, with the 'w' option. 'w' is a write mode which lets us edit and write new information to the file. Here s the catch that works for us ::: any existing json with the same target write name will be erased automatically.

So what we can do now, is simply write to the same filename with the new data

# add the id key-value pair (rmbr that it already has the "name" key value)
json_content["id"] = "134"

with open(PATH_TO_JSON,'w') as jsonfile:
    json.dump(json_content, jsonfile, indent=4) # you decide the indentation level

And there you go! data.json should be good to go for an good old POST request

if (File.Exists(path))
{
    File.Delete(path);
}

go to AndroidManifest.xml and change the android:icon="@mipmap/ic_launcher" to android:icon="@mipmap/(your image name)" suppose you have a image named telugu and you want it to be set as your app icon then change android:icon="@mipmap/telugu" and you have to copy and paste your image into mipmap folder thats it its so simple as i said

Starting from tslint v5.8.0 you can set an exclude property under your linterOptions key in your tslint.json file:

{
  "extends": "tslint:latest",
  "linterOptions": {
      "exclude": [
          "bin",
          "**/__test__",
          "lib/*generated.js"
      ]
  }
}

More information on this here.

The following code is perfectly fine and the right way (most exact, concise, and clear) to check if an object is null:

object obj = null;

//...

if (obj == null)
{
    // Do something
}

String.IsNullOrEmpty is a method existing for convenience so that you don't have to write the comparison code yourself:

private bool IsNullOrEmpty(string input)
{
    return input == null || input == string.Empty;
}

Additionally, there is a String.IsNullOrWhiteSpace method checking for null and whitespace characters, such as spaces, tabs etc.

SELECT DECODE(REGEXP_COUNT(:value,'\d'),LENGTH(:value),'Y','N') AS is_numeric FROM dual;

There are many ways but this one works perfect for me.

There's a problem with immediate asynchronous call of your function, because standard setTimeout/setInterval has a minimal timeout about several milliseconds even if you directly set it to 0. It caused by a browser specific work.

An example of code with a REAL zero delay wich works in Chrome, Safari, Opera

function setZeroTimeout(callback) {
var channel = new MessageChannel();
channel.port1.onmessage = callback;
channel.port2.postMessage('');
}

You can find more information here

And after the first manual call you can create an interval with your function.

Best way to pass data to one Activity to AnothetActivity by using Intent,

Check the code snipped

ActivityOne.java

Intent myIntent = new Intent(this, NewActivity.class);
myIntent.putExtra("key_name_one", "Your Data value here");
myIntent.putExtra("key_name_two", "Your data value here");
startActivity(myIntent)

On Your SecondActivity

SecondActivity.java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.view);

    Intent intent = getIntent();

    String valueOne = intent.getStringExtra("key_name_one");
    String valueTwo = intent.getStringExtra("key_name_two");
}

It is done to maintain the arrangement of bytes which is sent in the network(Endianness). Depending upon architecture of your device,data can be arranged in the memory either in the big endian format or little endian format. In networking, we call the representation of byte order as network byte order and in our host, it is called host byte order. All network byte order is in big endian format.If your host's memory computer architecture is in little endian format,htons() function become necessity but in case of big endian format memory architecture,it is not necessary.You can find endianness of your computer programmatically too in the following way:->

   int x = 1;
   if (*(char *)&x){
      cout<<"Little Endian"<<endl;
   }else{
      cout<<"Big Endian"<<endl;
   }

and then decide whether to use htons() or not.But in order to avoid the above line,we always write htons() although it does no changes for Big Endian based memory architecture.

Just like any other environment variable, with SET:

SET PATH=%PATH%;c:\whatever\else

If you want to have a little safety check built in first, check to see if the new path exists first:

IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else

If you want that to be local to that batch file, use setlocal:

setlocal
set PATH=...
set OTHERTHING=...

@REM Rest of your script

Read the docs carefully for setlocal/endlocal , and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.

The Syntax page should get you started with the basics.

I've found that sometimes, you point to the directory you'd assume was correct, and then it still states that it can't find the file in the attached source blah blah.

These times, I've realized that the last path element was "src". Just removing this path element (thus indeed pointing one level above the actual path where the "org" or "com" folder is located) magically makes it work.

Somehow, Eclipse seems to imply this "src" path element if present, and if you then have it included in the source path, Eclipse chokes. Or something like that.

To add to the above answers, there's a good article: Useful JVM Flags – Part 8 (GC Logging) by Patrick Peschlow.

A brief excerpt:

The flag -XX:+PrintGC (or the alias -verbose:gc) activates the “simple” GC logging mode

By default the GC log is written to stdout. With -Xloggc:<file> we may instead specify an output file. Note that this flag implicitly sets -XX:+PrintGC and -XX:+PrintGCTimeStamps as well.

If we use -XX:+PrintGCDetails instead of -XX:+PrintGC, we activate the “detailed” GC logging mode which differs depending on the GC algorithm used.

With -XX:+PrintGCTimeStamps a timestamp reflecting the real time passed in seconds since JVM start is added to every line.

If we specify -XX:+PrintGCDateStamps each line starts with the absolute date and time.

I think you should edit the anchor tag on bootstrap.css. Otherwise give customized style to the anchor tag with !important (to override the default style on bootstrap.css).

But it's not hard to write one:

public class CaseInsensitiveIndexOfTest extends TestCase {
    public void testOne() throws Exception {
        assertEquals(2, caseInsensitiveIndexOf("ABC", "xxabcdef"));
    }

    public static int caseInsensitiveIndexOf(String substring, String string) {
        return string.toLowerCase().indexOf(substring.toLowerCase());
    }
}

You can't unless you're using some kind of extended CSS such as SASS. However it is very reasonable to apply those two extra classes to .someDiv.

If .someDiv is unique I would also choose to give it an id and referencing it in css using the id.

here is my solution:

<style>
.sidebar-left{float:left;width:200px}
.content-right{float:right;width:700px}

.footer{clear:both;position:relative;height:1px;width:900px}
.bottom-element{position:absolute;top:-200px;left:0;height:200px;}

</style>

<div class="sidebar-left"> <p>content...</p></div>
<div class="content-right"> <p>content content content content...</p></div>

<div class="footer">
    <div class="bottom-element">bottom-element-in-sidebar</div>
</div>

Performs a in-memory streaming enumeration over both inputs and invokes the selector for each row. If there is no correlation at the current iteration, one of the selector arguments will be null.

Example:

   var result = left.FullOuterJoin(
         right, 
         x=>left.Key, 
         x=>right.Key, 
         (l,r) => new { LeftKey = l?.Key, RightKey=r?.Key });

• Requires an IComparer for the correlation type, uses the Comparer.Default if not provided.

As @Sean said, fcntl() is largely standardized, and therefore available across platforms. The ioctl() function predates fcntl() in Unix, but is not standardized at all. That the ioctl() worked for you across all the platforms of relevance to you is fortunate, but not guaranteed. In particular, the names used for the second argument are arcane and not reliable across platforms. Indeed, they are often unique to the particular device driver that the file descriptor references. (The ioctl() calls used for a bit-mapped graphics device running on an ICL Perq running PNX (Perq Unix) of twenty years ago never translated to anything else anywhere else, for example.)

Eugene's answer uses the correct function to get the data, but for posterity I'd like to spell out exactly how to use it in React v0.14+ (according to this answer):

  import ReactDOM from 'react-dom';
  //...
  componentDidMount() {
    var rect = ReactDOM.findDOMNode(this)
      .getBoundingClientRect()
  }

Is working for me perfectly, and I'm using the data to scroll to the top of the new component that just mounted.

There is one hacky way that should work on any activity, including the main one.

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

When orientation changes, Android generally will recreate your activity (unless you override it). This method is useful for 180 degree rotations, when Android doesn't recreate your activity.

I liked user1333423's solution except that it always re-sized every column; i needed to allow some columns to be fixed width. So in this version columns with a width set to "Auto" will be auto-sized and those set to a fixed amount will not be auto-sized.

public class AutoSizedGridView : GridView
{
    HashSet<int> _autoWidthColumns;

    protected override void PrepareItem(ListViewItem item)
    {
        if (_autoWidthColumns == null)
        {
            _autoWidthColumns = new HashSet<int>();

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

In C++ NULL expands to 0 or 0L. See this quote from Stroustrup's FAQ:

Should I use NULL or 0?

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

I just spend THREE WHOLE DAYS fighting against this issue.

I was using my ORACLE connection in Windows 7, and no problem. Last week I Just get a new computer with Windows 8. Install XAMPP 1.8.2. Every app PHP/MySQL on this server works fine. The problem came when I try to connect my php apps to Oracle DB.

Call to undefined function oci_pconnect()

And when I start/stop Apache with changes, a strange "Warning" on "PHP Startup" that goes to LOG with "PHP Warning: PHP Startup: in Unknown on line 0"

I did everything (uncommented php_oci8.dll and php_oci8_11g.dll, copy oci.dll to /ext directory, near /Apache and NOTHING it works. Download every version of Instant Client and NOTHING.

God came into my help. When I download ORACLE Instant Client 32 bits, everything works fine. phpinfo() displays oci8 info, and my app works fine.

So, NEVER MIND THAT YOUR WINDOWS VERSION BE x64. The link are between XAMPP and ORACLE Instant Client.

Referring to SimpleDataFormat JavaDoc:

Letter | Date or Time Component | Presentation | Examples
---------------------------------------------------------
   H   |  Hour in day (0-23)    |    Number    |    0
   h   |  Hour in am/pm (1-12)  |    Number    |    12

Maybe try something like:

import matplotlib.pyplot as plt
import numpy
from scipy import stats
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = stats.kde.gaussian_kde(data)
x = numpy.arange(0., 8, .1)
plt.plot(x, density(x))
plt.show()

You can easily replace gaussian_kde() by a different kernel density estimate.

I have resolved the problem by adding below code to manifest,

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_stat_name" />

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/black" />

where ic_stat_name created on Android Studio Right Click on res >> New >>Image Assets >> IconType(Notification)

And one more step I have to do on server php side with notification payload

$message = [
    "message" => [
        "notification" => [
            "body"  => $title , 
            "title" => $message
        ],

        "token" => $token,

    "android" => [
           "notification" => [
            "sound"  => "default",
            "icon"  => "ic_stat_name"
            ]
        ],

       "data" => [
            "title" => $title,
            "message" => $message
         ]


    ]
];

Note the section

    "android" => [
           "notification" => [
            "sound"  => "default",
            "icon"  => "ic_stat_name"
            ]
        ]

where icon name is "icon" => "ic_stat_name" should be the same set on manifest.

Laravel 5.8 simple and easy

you can do this all in a form request with quite nicely. . .

first make a field by which you can pass the id (invisible) in the normal edit form. i.e.,

 <div class="form-group d-none">
      <input class="form-control" name="id" type="text" value="{{ $example->id }}" >
 </div>

... Then be sure to add the Rule class to your form request like so:

use Illuminate\Validation\Rule;

... Add the Unique rule ignoring the current id like so:

public function rules()
{
    return [
          'example_field_1'  => ['required', Rule::unique('example_table')->ignore($this->id)],
          'example_field_2'  => 'required',

    ];

... Finally type hint the form request in the update method the same as you would the store method, like so:

 public function update(ExampleValidation $request, Examle $example)
{
    $example->example_field_1 = $request->example_field_1;
    ...
    $example->save();

    $message = "The aircraft was successully updated";


    return  back()->with('status', $message);


}

This way you won't repeat code unnecessarily :-)

you can simply use onBackPressed();

or if you are using fragment you can use getActivity().onBackPressed()

Use strtol if you have libc available like the top answer suggests. However if you like custom stuff or are on a microcontroller without libc or so, you may want a slightly optimized version without complex branching.

#include <inttypes.h>


/**
 * xtou64
 * Take a hex string and convert it to a 64bit number (max 16 hex digits).
 * The string must only contain digits and valid hex characters.
 */
uint64_t xtou64(const char *str)
{
    uint64_t res = 0;
    char c;

    while ((c = *str++)) {
        char v = (c & 0xF) + (c >> 6) | ((c >> 3) & 0x8);
        res = (res << 4) | (uint64_t) v;
    }

    return res;
} 

The bit shifting magic boils down to: Just use the last 4 bits, but if it is an non digit, then also add 9.

This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.

If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.

Look at here for a similar problem that occured Silverlight: Value does not fall within the expected range exception

Cheers,

The method for converting a string to a long is Long.parseLong. Modifying your example:

String s = "1333073704000";
long l = Long.parseLong(s);
// Now l = 1333073704000
