change your method to:

$scope.toggleChecked = function (index) {
    $scope.checked.push($scope.items[index]);
    $scope.items.splice(index, 1);
};

Alternatively you can use a Docker image which already has ping installed, e.g. busybox:

docker run --rm busybox ping SERVER_NAME -c 2

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

You need to use an explicit color value (e.g. #000 or blue) for the color-property. none is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active, too.

A rect can't contain a text element. Instead transform a g element with the location of text and rectangle, then append both the rectangle and the text to it:

var bar = chart.selectAll("g")
    .data(data)
  .enter().append("g")
    .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

bar.append("rect")
    .attr("width", x)
    .attr("height", barHeight - 1);

bar.append("text")
    .attr("x", function(d) { return x(d) - 3; })
    .attr("y", barHeight / 2)
    .attr("dy", ".35em")
    .text(function(d) { return d; });

Multi-line labels are also a little tricky, you might want to check out this wrap function.

Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.

To create a new branch with a copy of your current state

git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server

Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.

However I get an error which doesn't make sense seeing as the column's data type was properly modified?

| Level | Code | Msg | Warn | 12 | Data truncated for column 'incoming_Cid' at row 1

You can often get this message when you are doing something like the following:

REPLACE INTO table2 (SELECT * FROM table1);

Resulted in our case in the following error:

SQL Exception: Data truncated for column 'level' at row 1

The problem turned out to be column misalignment that resulted in a tinyint trying to be stored in a datetime field or vice versa.

Something like this should do it. Just grab the value from the registry

For .NET 1-4:

Framework is the highest installed version, SP is the service pack for that version.

RegistryKey installed_versions = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP");
string[] version_names = installed_versions.GetSubKeyNames();
//version names start with 'v', eg, 'v3.5' which needs to be trimmed off before conversion
double Framework = Convert.ToDouble(version_names[version_names.Length - 1].Remove(0, 1), CultureInfo.InvariantCulture);
int SP = Convert.ToInt32(installed_versions.OpenSubKey(version_names[version_names.Length - 1]).GetValue("SP", 0));

For .NET 4.5+ (from official documentation):

using System;
using Microsoft.Win32;


...


private static void Get45or451FromRegistry()
{
    using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey("SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full\\")) {
        int releaseKey = Convert.ToInt32(ndpKey.GetValue("Release"));
        if (true) {
            Console.WriteLine("Version: " + CheckFor45DotVersion(releaseKey));
        }
    }
}


...


// Checking the version using >= will enable forward compatibility,

    return "No 4.5 or later version detected";
}

$route: This is used for deep-linking URLs to controllers and views (HTML partials) and watches $location.url() in order to map the path from an existing definition of route.

When we use ngRoute, the route is configured with $routeProvider and when we use ui-router, the route is configured with $stateProvider and $urlRouterProvider.

<div ng-view></div>
    $routeProvider
        .when('/contact/', {
            templateUrl: 'app/views/core/contact/contact.html',
            controller: 'ContactCtrl'
        });


<div ui-view>
    <div ui-view='abc'></div>
    <div ui-view='abc'></div>
   </div>
    $stateProvider
        .state("contact", {
            url: "/contact/",
            templateUrl: '/app/Aisel/Contact/views/contact.html',
            controller: 'ContactCtrl'
        });

After you commit your object into the db the object receives a value in its ID field.

So:

myObject.Field1 = "value";

// Db is the datacontext
db.MyObjects.InsertOnSubmit(myObject);
db.SubmitChanges();

// You can retrieve the id from the object
int id = myObject.ID;

According to RFC 2397, no, there isn't.

Nor does there appear to be any attribute of the <a> element that you can use either.

However HTML5 has subsequently introduced the download attribute on the <a> element, although at the time of writing support is not universal (no MSIE support, for example)

1. A single bracket ([) usually actually calls a program named [; man test or man [ for more info. Example:

   $ VARIABLE=abcdef
   $ if [ $VARIABLE == abcdef ] ; then echo yes ; else echo no ; fi
   yes
   

2. The double bracket ([[) does the same thing (basically) as a single bracket, but is a bash builtin.

   $ VARIABLE=abcdef
   $ if [[ $VARIABLE == 123456 ]] ; then echo yes ; else echo no ; fi
   no
   

3. Parentheses (()) are used to create a subshell. For example:

   $ pwd
   /home/user 
   $ (cd /tmp; pwd)
   /tmp
   $ pwd
   /home/user
   

   As you can see, the subshell allowed you to perform operations without affecting the environment of the current shell.

4. (a) Braces ({}) are used to unambiguously identify variables. Example:

   $ VARIABLE=abcdef
   $ echo Variable: $VARIABLE
   Variable: abcdef
   $ echo Variable: $VARIABLE123456
   Variable:
   $ echo Variable: ${VARIABLE}123456
   Variable: abcdef123456
   

   (b) Braces are also used to execute a sequence of commands in the current shell context, e.g.

   $ { date; top -b -n1 | head ; } >logfile 
   # 'date' and 'top' output are concatenated, 
   # could be useful sometimes to hunt for a top loader )
   
   $ { date; make 2>&1; date; } | tee logfile
   # now we can calculate the duration of a build from the logfile
   

There is a subtle syntactic difference with ( ), though (see bash reference) ; essentially, a semicolon ; after the last command within braces is a must, and the braces {, } must be surrounded by spaces.

I saved NSDictionary normally and able to get it correctly.

 dictForaddress = placemark.addressDictionary! as NSDictionary
        let userDefaults = UserDefaults.standard
        userDefaults.set(dictForaddress, forKey:Constants.kAddressOfUser)

// For getting data from NSDictionary.

let userDefaults = UserDefaults.standard
    let dictAddress = userDefaults.object(forKey: Constants.kAddressOfUser) as! NSDictionary

I'm not answering why it is so, but only wanted to show a way around that limitation in SQL Server by using CROSS APPLY to create the alias. You then use it in the GROUP BY clause, like so:

SELECT 
 itemName as ItemName,
 FirstLetter,
 Count(itemName)
FROM table1
CROSS APPLY (SELECT substring(itemName, 1,1) as FirstLetter) Alias
GROUP BY itemName, FirstLetter

Take a step back! Firstly, you're assuming the user is using a foreign locale on their device, which is not a sound assumption for justifying taking over the button text of the file picker, and making it say what you want it to.

It is reasonable that you want to control every item of language visible on your page. The content of the File Upload control is not part of the HTML though. There is more content behind this control, for example, in WebKit, it also says "No file chosen" next to the button.

There are very hacky workarounds that attempt this (e.g. like those mentioned in @ChristopheD's answer), but none of them truly succeed:

• To a screen reader, the file control will still say "Browse..." or "Choose File", and a custom file upload will not be announced as a file upload control, but just a button or a text input.
• Many of them fail to display the chosen file, or to show that the user has no longer chosen a file
• Many of them look nothing like the native control, so might look strange on non-standard devices.
• Keyboard support is typically poor.
• An author-created UI component can never be as fully functional as its native equivalent (and the closer you get it to behave to suppose IE10 on Windows 7, the more it will deviate from other Browser and Operating System combinations).
• Modern browsers support drag & drop into the native file upload control.
• Some techniques may trigger heuristics in security software as a potential ‘click-jacking’ attempt to trick the user into uploading file.

Deviating from the native controls is always a risky thing, there is a whole host of different devices your users could be using, and whatever workaround you choose, you will not have tested it in every one of those devices.

However, there is an even bigger reason why all attempts fail from a User Experience perspective: there is even more non-localized content behind this control, the file selection dialog itself. Once the user is subject to traversing their file system or what not to select a file to upload, they will be subjected to the host Operating System locale.

Are you sure you're doing your user any justice by deviating from the native control, just to localize the text, when as soon as they click it, they're just going to get the Operating System locale anyway?

The best you can do for your users is to ensure you have adequate localised guidance surrounding your file input control. (e.g. Form field label, hint text, tooltip text).

Sorry. :-(

This answer is for those looking for any justification not to localise the file upload control.

You can specify the color option as a list directly to the plot function.

from matplotlib import pyplot as plt
from itertools import cycle, islice
import pandas, numpy as np  # I find np.random.randint to be better

# Make the data
x = [{i:np.random.randint(1,5)} for i in range(10)]
df = pandas.DataFrame(x)

# Make a list by cycling through the colors you care about
# to match the length of your data.
my_colors = list(islice(cycle(['b', 'r', 'g', 'y', 'k']), None, len(df)))

# Specify this list of colors as the `color` option to `plot`.
df.plot(kind='bar', stacked=True, color=my_colors)

To define your own custom list, you can do a few of the following, or just look up the Matplotlib techniques for defining a color item by its RGB values, etc. You can get as complicated as you want with this.

my_colors = ['g', 'b']*5 # <-- this concatenates the list to itself 5 times.
my_colors = [(0.5,0.4,0.5), (0.75, 0.75, 0.25)]*5 # <-- make two custom RGBs and repeat/alternate them over all the bar elements.
my_colors = [(x/10.0, x/20.0, 0.75) for x in range(len(df))] # <-- Quick gradient example along the Red/Green dimensions.

The last example yields the follow simple gradient of colors for me:

I didn't play with it long enough to figure out how to force the legend to pick up the defined colors, but I'm sure you can do it.

In general, though, a big piece of advice is to just use the functions from Matplotlib directly. Calling them from Pandas is OK, but I find you get better options and performance calling them straight from Matplotlib.

Switch is not considered as loop so you cannot use Continue inside a case statement in switch...

I'm using this function based on @Murph answer. It searches inside the current directory and lists the full path:

function findit
{
$filename = $args[0];
gci -recurse -filter "*${filename}*" -file -ErrorAction SilentlyContinue | foreach-object {
    $place_path = $_.directory
    echo "${place_path}\${_}"
    }
}

Example usage: findit myfile

If you are currently not on branch master, that's super easy:

git branch -f master 1258f0d0aae

This does exactly what you want: It points master at the given commit, and does nothing else.

If you are currently on master, you need to get into detached head state first. I'd recommend the following two command sequence:

git checkout 1258f0d0aae    #detach from master
git branch -f master HEAD   #exactly as above

#optionally reattach to master
git checkout master

Be aware, though, that any explicit manipulation of where a branch points has the potential to leave behind commits that are no longer reachable by any branches, and thus become object to garbage collection. So, think before you type git branch -f!

This method is better than the git reset --hard approach, as it does not destroy anything in the index or working directory.

You need to add the original repository (the one that you forked) as a remote.

git remote add github (clone url for the orignal repository)

Then you need to bring in the changes to your local repository

git fetch github

Now you will have all the branches of the original repository in your local one. For example, the master branch will be github/master. With these branches you can do what you will. Merge them into your branches etc

String1.scan(/<([^>]*)>/).last.first

scan creates an array which, for each <item> in String1 contains the text between the < and the > in a one-element array (because when used with a regex containing capturing groups, scan creates an array containing the captures for each match). last gives you the last of those arrays and first then gives you the string in it.

In the Params I have added model.Email and model.Password, work for me well. Thanks for the question. I tried the same thing in headers did not work. But it worked on Body with form-data and x-www-form-urlencoded.

Actually you get promise on $http.get.

Try to use followed flow:

<li ng-repeat="document in documents" ng-class="IsFiltered(document.Filtered)">
    <span><input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" /></span>
    <span>{{document.Name}}</span>
</li>

Where documents is your array.

$scope.documents = [];

$http.get('/Documents/DocumentsList/' + caseId).then(function(result) {
    result.data.forEach(function(val, i) { 
        $scope.documents.push(/* put data here*/);
    });
}, function(error) {
    alert(error.message);
});                       

This is happen because another instance of sql server is running. So you need to kill first then you can able to login to SQL Server.

For that go to Task Manager and Kill or End Task the SQL Server service then go to Services.msc and start the SQL Server service.

multiprocessing is not like threading. Each child process will get a copy of the main process's memory. Generally state is shared via communication (pipes/sockets), signals, or shared memory.

Multiprocessing makes some abstractions available for your use case - shared state that's treated as local by use of proxies or shared memory: http://docs.python.org/library/multiprocessing.html#sharing-state-between-processes

Relevant sections:

• http://docs.python.org/library/multiprocessing.html#shared-ctypes-objects
• http://docs.python.org/library/multiprocessing.html#module-multiprocessing.managers

For Swift use this,

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    var segueID = segue.identifier

    if(segueID! == "yourSegueName"){

        var yourVC:YourViewController = segue.destinationViewController as YourViewController

        yourVC.objectOnYourVC = setObjectValueHere!

    }
}

For python bindings it will be :

element.get_attribute('value')

The simplest approach would be to edit the webserver, most likely an Apache2 installation, configuration and give phpmyadmin a different name.

A second approach would be to limit the IP addresses from where phpmyadmin may be accessed (e.g. only local lan or localhost).

If you want to do this for all submodules, without having to change directories, you can perform

git submodule foreach git reset --hard

You can also use the recursive flag to apply to all submodules:

git submodule foreach --recursive git reset --hard

Before understanding next, you need to have a little idea of Request-Response cycle in node though not much in detail. It starts with you making an HTTP request for a particular resource and it ends when you send a response back to the user i.e. when you encounter something like res.send(‘Hello World’);

let’s have a look at a very simple example.

app.get('/hello', function (req, res, next) {
  res.send('USER')
})

Here we do not need next(), because resp.send will end the cycle and hand over the control back to the route middleware.

Now let’s take a look at another example.

app.get('/hello', function (req, res, next) {
  res.send("Hello World !!!!");
});

app.get('/hello', function (req, res, next) {
  res.send("Hello Planet !!!!");
});

Here we have 2 middleware functions for the same path. But you always gonna get the response from the first one. Because that is mounted first in the middleware stack and res.send will end the cycle.

But what if we always do not want the “Hello World !!!!” response back. For some conditions we may want the "Hello Planet !!!!" response. Let’s modify the above code and see what happens.

app.get('/hello', function (req, res, next) {
  if(some condition){
    next();
    return;
  }
  res.send("Hello World !!!!");  
});

app.get('/hello', function (req, res, next) {
  res.send("Hello Planet !!!!");
});

What’s the next doing here. And yes you might have gusses. It’s gonna skip the first middleware function if the condition is true and invoke the next middleware function and you will have the "Hello Planet !!!!" response.

So, next pass the control to the next function in the middleware stack.

What if the first middleware function does not send back any response but do execute a piece of logic and then you get the response back from second middleware function.

Something like below:-

app.get('/hello', function (req, res, next) {
  // Your piece of logic
  next();
});

app.get('/hello', function (req, res, next) {
  res.send("Hello !!!!");
});

In this case you need both the middleware functions to be invoked. So, the only way you reach the second middleware function is by calling next();

What if you do not make a call to next. Do not expect the second middleware function to get invoked automatically. After invoking the first function your request will be left hanging. The second function will never get invoked and you will not get back the response.

If want to delete an entry from the the table in Room simply call this function,

@Dao
public interface myDao{
    @Delete
    void delete(MyModel model);
}

Update: And if you want to delete complete table, call below function,

  @Query("DELETE FROM MyModel")
  void delete();

Note: Here MyModel is a Table Name.

an alternative would be to do something like:

SELECT
   CAST(P0.seconds as bigint) as seconds
FROM
   (
   SELECT
      seconds
   FROM
      TableName
   WHERE
      ISNUMERIC(seconds) = 1
   ) P0

Following short code can help:

df3 = df3.rename(columns={c: c.replace(' ', '') for c in df3.columns})

Remove spaces from columns.

I'm using php-5.4.45 and I got the same problem.

If you are a php-fpm user, try edit php-fpm.conf and change listen.owner and listen.group to the right one. My nginx user is apache, so here I change these to params to apache, then it works well for me.

For apache user, I guess you should edit your fast-cgi params refer the two params I mention above.

Two things:

1. Only need one (1) equals sign to evaluate
2. You need to specify a length on the VARCHAR - the default is a single character.

Use:

DECLARE @temp VARCHAR(10)
    SET @temp = 'm'

IF @temp = 'm'
  SELECT 'yes'
ELSE
  SELECT 'no'

VARCHAR(10) means the VARCHAR will accommodate up to 10 characters. More examples of the behavior -

DECLARE @temp VARCHAR
    SET @temp = 'm'

IF @temp = 'm'
  SELECT 'yes'
ELSE
  SELECT 'no'

...will return "yes"

DECLARE @temp VARCHAR
    SET @temp = 'mtest'

IF @temp = 'm'
  SELECT 'yes'
ELSE
  SELECT 'no'

...will return "no".

Sometimes this error happens because of unexpected CR characters in file, usually because the file was generated on a Windows system which uses CR line endings. You can fix this by running os2unix or tr, for example:

tr -d '\015' < yourscript.sh > newscript.sh

This removes any CR characters from the file.

You can also set a Constraint on a Table with the KEY fields and set On Conflict "Ignore"

When an applicable constraint violation occurs, the IGNORE resolution algorithm skips the one row that contains the constraint violation and continues processing subsequent rows of the SQL statement as if nothing went wrong. Other rows before and after the row that contained the constraint violation are inserted or updated normally. No error is returned when the IGNORE conflict resolution algorithm is used.

SQLite Documentation

OK, this question has been answered and answer accepted but someone asked me to put my answer so there you go.

First of all, it is not possible to say for sure. It is an internal implementation detail and not documented. However, based on the objects included in the other object. Now, how do we calculate the memory requirement for our cached objects?

I had previously touched this subject in this article:

Now, how do we calculate the memory requirement for our cached objects? Well, as most of you would know, Int32 and float are four bytes, double and DateTime 8 bytes, char is actually two bytes (not one byte), and so on. String is a bit more complex, 2*(n+1), where n is the length of the string. For objects, it will depend on their members: just sum up the memory requirement of all its members, remembering all object references are simply 4 byte pointers on a 32 bit box. Now, this is actually not quite true, we have not taken care of the overhead of each object in the heap. I am not sure if you need to be concerned about this, but I suppose, if you will be using lots of small objects, you would have to take the overhead into consideration. Each heap object costs as much as its primitive types, plus four bytes for object references (on a 32 bit machine, although BizTalk runs 32 bit on 64 bit machines as well), plus 4 bytes for the type object pointer, and I think 4 bytes for the sync block index. Why is this additional overhead important? Well, let’s imagine we have a class with two Int32 members; in this case, the memory requirement is 16 bytes and not 8.

WHY JSON : You can use it with most of the programming languages, string created by serialize() function of php is readable in PHP only, and you will not like to store such things in your databases specially if database is shared among applications written in different programming languages

To get a URL parameter's value, use req.params

app.get('/p/:tagId', function(req, res) {
  res.send("tagId is set to " + req.params.tagId);
});

// GET /p/5
// tagId is set to 5

If you want to get a query parameter ?tagId=5, then use req.query

app.get('/p', function(req, res) {
  res.send("tagId is set to " + req.query.tagId);
});

// GET /p?tagId=5
// tagId is set to 5

Here's a probable use-case, from the top:

You're going to pull some changes, but oops, you're not up to date:

git fetch origin
git pull origin master

From ssh://[email protected]:22/projectname
 * branch            master     -> FETCH_HEAD
Updating a030c3a..ee25213
error: Entry 'filename.c' not uptodate. Cannot merge.

So you get up-to-date and try again, but have a conflict:

git add filename.c
git commit -m "made some wild and crazy changes"
git pull origin master

From ssh://[email protected]:22/projectname
 * branch            master     -> FETCH_HEAD
Auto-merging filename.c
CONFLICT (content): Merge conflict in filename.c
Automatic merge failed; fix conflicts and then commit the result.

So you decide to take a look at the changes:

git mergetool

Oh my, oh my, upstream changed some things, but just to use my changes...no...their changes...

git checkout --ours filename.c
git checkout --theirs filename.c
git add filename.c
git commit -m "using theirs"

And then we try a final time

git pull origin master

From ssh://[email protected]:22/projectname
 * branch            master     -> FETCH_HEAD
Already up-to-date.

Ta-da!

To return a value from a VBScript function, assign the value to the name of the function, like this:

Function getNumber
    getNumber = "423"

You could use an arbitrary count of arrays and map on the same index new objects.

var array1 = [{ id: "abdc4051", date: "2017-01-24" }, { id: "abdc4052", date: "2017-01-22" }],_x000D_
    array2 = [{ id: "abdc4051", name: "ab" }, { id: "abdc4052", name: "abc" }],_x000D_
    result = [array1, array2].reduce((a, b) => a.map((c, i) => Object.assign({}, c, b[i])));_x000D_
    _x000D_
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Actually it is much more useful use the method that came with the library like this $(".datepicker").datepicker("clearDates");

I recommend you to always take a look at the documentation of the library, here is the one I used for this.

You could use the ViewCommand design pattern. It describes a method for the MVVM design pattern to control a View from a ViewModel with commands.

I've implemented it based on King A.Majid's suggestion to use the MVVM Light Messenger class. The ViewCommandManager class handles invoking commands in connected views. It's basically the other direction of regular Commands, for these cases when a ViewModel needs to do some action in its View. It uses reflection like data-bound commands and WeakReferences to avoid memory leaks.

if you want to populate a table in SQL SERVER you can use while statement as follows:

declare @llenandoTabla INT = 0;
while @llenandoTabla < 10000
begin
insert into employeestable // Name of my table
(ID, FIRSTNAME, LASTNAME, GENDER, SALARY) // Parameters of my table
VALUES 
(555, 'isaias', 'perez', 'male', '12220') //values
set @llenandoTabla = @llenandoTabla + 1;
end

Hope it helps.

Function title: goobox

tags: image hosting, regex, URL, google drive, dropbox, advanced

• return: string, Returns a string URL that can be used directly as the source of an image.
• when you host an image on google drive or dropbox you can't use the direct URL of your file to be an image source.
• you need to make changes to this URL to use it directly as an image source.
• goobox() will take the URL of your image file, and change it to be used directly as an image source.
• Important: you need to check your files' permissions first, and whether it's public.
• live example: https://ybmex.csb.app/

If column A contains the amounts to be reimbursed, and column B contains the "yes/no" indicating whether the reimbursement has been made, then either of the following will work, though the first option is recommended:

=SUMIF(B:B,"No",A:A)

or

=SUMIFS(A:A,B:B,"No")

Here is an example that will display the amounts paid and outstanding for a small set of sample data.

 A         B            C                   D
 Amount    Reimbursed?  Total Paid:         =SUMIF(B:B,"Yes",A:A)
 $100      Yes          Total Outstanding:  =SUMIF(B:B,"No",A:A)
 $200      No           
 $300      No
 $400      Yes
 $500      No

Just use .get(0) to grab the native element, and get its outerHTML property:

var $elem = $('<a href="#">Some element</a>');
console.log("HTML is: " + $elem.get(0).outerHTML);

As mentioned by others, Heap can do findMin or findMax in O(1) but not both in the same data structure. However I disagree that Heap is better in findMin/findMax. In fact, with a slight modification, the BST can do both findMin and findMax in O(1).

In this modified BST, you keep track of the the min node and max node everytime you do an operation that can potentially modify the data structure. For example in insert operation you can check if the min value is larger than the newly inserted value, then assign the min value to the newly added node. The same technique can be applied on the max value. Hence, this BST contain these information which you can retrieve them in O(1). (same as binary heap)

In this BST (Balanced BST), when you pop min or pop max, the next min value to be assigned is the successor of the min node, whereas the next max value to be assigned is the predecessor of the max node. Thus it perform in O(1). However we need to re-balance the tree, thus it will still run O(log n). (same as binary heap)

I would be interested to hear your thought in the comment below. Thanks :)

Update

Cross reference to similar question Can we use binary search tree to simulate heap operation? for more discussion on simulating Heap using BST.

Use the below code:

import base64

#Taking input through the terminal.
welcomeInput= raw_input("Enter 1 to convert String to Base64, 2 to convert Base64 to String: ") 

if(int(welcomeInput)==1 or int(welcomeInput)==2):
    #Code to Convert String to Base 64.
    if int(welcomeInput)==1:
        inputString= raw_input("Enter the String to be converted to Base64:") 
        base64Value = base64.b64encode(inputString.encode())
        print "Base64 Value = " + base64Value
    #Code to Convert Base 64 to String.
    elif int(welcomeInput)==2:
        inputString= raw_input("Enter the Base64 value to be converted to String:") 
        stringValue = base64.b64decode(inputString).decode('utf-8')
        print "Base64 Value = " + stringValue

else:
    print "Please enter a valid value."

No need for an extra directive, here's my take on this:

HTML:

<div class="form-group" data-ng-class="{ 'has-error': submitted && !form.new_passwd.$valid }">
    <input type="password" name="new_passwd" class="form-control" data-ng-model="data.new_passwd" placeholder="New Password" required data-ng-pattern="passwdRegex">
    <small class="help-block" data-ng-show="submitted && form.new_passwd.$error.required">New password is required!</small>
    <small class="help-block" data-ng-show="submitted && !form.new_passwd.$error.required && form.new_passwd.$error.pattern">New password is not strong enough!</small>
</div>

<div class="form-group" data-ng-class="{ 'has-error': submitted && !form.new_passwd_conf.$valid }">
    <input type="password" name="new_passwd_conf" class="form-control" data-ng-model="data.new_passwd_conf" placeholder="Confirm New Password" required data-ng-pattern="passwdConfRegex">
    <small class="help-block" data-ng-show="submitted && form.new_passwd_conf.$error.required">New password confirmation is required!</small>
    <small class="help-block" data-ng-show="submitted && !form.new_passwd_conf.$error.required && form.new_passwd_conf.$error.pattern">New password confirmation does not match!</small>
</div>

Javascript:

$scope.passwdRegex = /^(?=.*[A-Z])(?=.*[a-z])(?=.*\d)(?=.*[^\da-zA-Z]).{8,}$/;
$scope.$watch('data.new_passwd', function() {
    $scope.passwdConfRegex = new RegExp(Regex.escape($scope.data.new_passwd));
});

where Regex.escape() can be found here.

Works like a charm!

The && function is not vectorized. You need the & function:

I know this is late, but this is how I normally do it,

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

If you are using Google Play App Signing, instead of getting the SHA from the keystore, an easier way is to go to the Google Play Console > Your app > Release Management > App signing and look for your upload certificate.

This is because Oracle internally changes empty string to NULL values. Oracle simply won't let insert an empty string.

On the other hand, SQL Server would let you do what you are trying to achieve.

There are 2 workarounds here:

1. Use another column that states whether the 'description' field is valid or not
2. Use some dummy value for the 'description' field where you want it to store empty string. (i.e. set the field to be 'stackoverflowrocks' assuming your real data will never encounter such a description value)

Both are, of course, stupid workarounds :)

$no_newlines = str_replace("\r", '', str_replace("\n", '', $str_with_newlines));

You could store the last insert id in a variable :

INSERT INTO table1 (title,userid) VALUES ('test', 1); 
SET @last_id_in_table1 = LAST_INSERT_ID();
INSERT INTO table2 (parentid,otherid,userid) VALUES (@last_id_in_table1, 4, 1);    

Or get the max id frm table1

INSERT INTO table1 (title,userid) VALUES ('test', 1); 
INSERT INTO table2 (parentid,otherid,userid) VALUES (LAST_INSERT_ID(), 4, 1); 
SELECT MAX(id) FROM table1;   

In my case this error was caused by the existence of the _MigrationsHistory table in the database. Deleting that table fixed the problem. Not sure how that table got into our test environment database.

This is because $pjs is an one-element-array of objects, so first you should access the array element, which is an object and then access its attributes.

echo $pjs[0]->player_name;

Actually dump result that you pasted tells it very clearly.

Although everyone has already given you the answer , I'll mention a way which makes it easy to pass a datetime into a function

[ERROR:cannot convert system.datetime? to system.datetime]

DateTime? dt = null;
DateTime dte = Convert.ToDateTime(dt);

Now you may pass dte inside the function without any issues.

'request.user' has the logged in user.
'request.user.username' will return username of logged in user.

i was facing the same issue and solved it by removing the xmlns:wsu attribute.Try not adding it in the usernameToken.Hope this solves your issue too.

We encountered the same error message, with a completely different cause.

Setup:

• App target, all Obj-C code
• Unit Test target with a single swift test case & a bridging header referring to app code

When we added the second swift test case, after a clean (or on a team mate's machine), we saw this error when building the unit test target.

It was fixed by adding a dummy Obj-C class to the unit test target.

A SELECT INTO statement creates the table for you. There is no need for the CREATE TABLE statement before hand.

What is happening is that you create #ivmy_cash_temp1 in your CREATE statement, then the DB tries to create it for you when you do a SELECT INTO. This causes an error as it is trying to create a table that you have already created.

Either eliminate the CREATE TABLE statement or alter your query that fills it to use INSERT INTO SELECT format.

If you need a unique ID added to your new row then it's best to use SELECT INTO... since IDENTITY() only works with this syntax.

I got this error, hope this will help someone:

const firstName = 'Joe';
const lastName = 'Blogs';
const wholeName = firstName + ' ' lastName + '.';

The problem was that I was missing a plus (+) between the empty space and lastName. This is a super simplified example: I was concatenating about 9 different parts so it was hard to spot the error.

Summa summarum: if you get "SyntaxError: missing ; before statement", don't look at what is wrong with the the semicolon (;) symbols in your code, look for an error in syntax on that line.

Using a typedef avoids having to write struct every time you declare a variable of that type:

struct elem
{
 int i;
 char k;
};
elem user; // compile error!
struct elem user; // this is correct

Check if you mixed tabs and spaces, that is a frequent source of indentation errors.

I have created my own iterator to iterate over Outlook objects via python. The issue is that python tries to iterates starting with Index[0], but outlook expects for first item Index[1]... To make it more Ruby simple, there is below a helper class Oli with following methods:

.items() - yields a tuple(index, Item)...

.prop() - helping to introspect outlook object exposing available properties (methods and attributes)

from win32com.client import constants
from win32com.client.gencache import EnsureDispatch as Dispatch

outlook = Dispatch("Outlook.Application")
mapi = outlook.GetNamespace("MAPI")

class Oli():
    def __init__(self, outlook_object):
        self._obj = outlook_object

    def items(self):
        array_size = self._obj.Count
        for item_index in xrange(1,array_size+1):
            yield (item_index, self._obj[item_index])

    def prop(self):
        return sorted( self._obj._prop_map_get_.keys() )

for inx, folder in Oli(mapi.Folders).items():
    # iterate all Outlook folders (top level)
    print "-"*70
    print folder.Name

    for inx,subfolder in Oli(folder.Folders).items():
        print "(%i)" % inx, subfolder.Name,"=> ", subfolder

can i write my html like this with use css ?

Yes you can but then you will have to use the :nth-child() pseudo selector (which has limited support though):

table.alternate_color tr:nth-child(odd) td{
   /* styles here */
}
table.alternate_color tr:nth-child(even) td{
   /* styles here */
}

You can get it like

[ x[0] for x in a]

which will return a list of the first element of each list in a

I ran into the same problem, when I was using a static methods in a Util class, just like you had used CSMessageUtility.CSDetails.

The problem was that during the static initialization of the class (using the static constructor), the framework also initialize the the static variables (fields) in the class. I had a static variable that attempts to read values from app.config, and app.config was missing the respective settings, thus resulting in an un-handled exception. This resulted in getting the

"Object reference not set to an instance of an object."

as the inner exception.

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

In your activity you can create a method with the same name (clickEvent(View v)), and that's it! You can see the log and the toast text too.

public void clickEvent(View v)
  {
    Log.i(SystemSettings.APP_TAG + " : " + HomeActivity.class.getName(), "Entered onClick method");
    Toast.makeText(v.getContext(),
            "The favorite list would appear on clicking this icon",

When i have this problem, i find running the cleanup command directly on the problem path generally seems to work. Then I'll run cleanup from the working root again, and it'll complain about some other directory. and i just repeat until it stops complaining.

I would recommend against mixing camel case and underscore separation (like you proposed for struct members). This is confusing. You'd think, hey I have get_length so I should probably have make_subset and then you find out it's actually makeSubset. Use the principle of least astonishment, and be consistent.

I do find CamelCase useful to type names, like structs, typedefs and enums. That's about all, though. For all the rest (function names, struct member names, etc.) I use underscore_separation.

Break ends the current loop/control structure and skips to the end of it, no matter how many more times the loop otherwise would have repeated.

Continue skips to the beginning of the next iteration of the loop.

• Firebase is a real-time engine with backward connectivity. I.e. you might build a cross-platform app where clients subscribe to events on specific data and server actively informs clients about changes
• The data layer is hosted for you. Mind that it is highly scalable. It's a nice kickstarter solution. Including auth management
• Geo-Fire. Real-time geo coordinates solution.
• Evident drawbacks of Firebase are:
  • You have to pay for it as soon as you start growing
  • You can't host datalayer (if owning data is critical or you develop an app for some separated subnet)

EDIT: here is a nice article how to replace Firebase in your app with Node.js+MongoDb. It shows how much work you would have to do on your own, and explains, IMHO, why a startup (small app) should begin with Firebase (if real-time updates to clients are required) and proceed with MongoDb (in any case self-written solution) if the project keeps evolving

EDIT 2: after being acquired by Google Firebase now offers various perks on top of its basic features which you would struggle to build on your own:

• For development

  • Cloud Messaging: Deliver and receive messages across platforms reliably
  • File Storage: Easy file storage (including iOS)
  • Hosting: deliver static files from Firebase's servers (Included in Free plan)
  • Crash Reporting: Not a full logging service, but crucial help

• For growth

  • Remote Config: Customize your app on the fly: suitable for A/B testing
  • Dynamic Links: Send users to the right place inside your app
  • Notifications: Engage with users at the right moment

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)

With the TabLayout provided by the Material Components Library just use the selectTab method:

TabLayout tabLayout = findViewById(R.id.tab_layout);
tabLayout.selectTab(tabLayout.getTabAt(index));

It requires version 1.1.0.

(left, upper, right, lower) means two points,

1. (left, upper)
2. (right, lower)

with an 800x600 pixel image, the image's left upper point is (0, 0), the right lower point is (800, 600).

So, for cutting the image half:

from PIL import Image
img = Image.open("ImageName.jpg")

img_left_area = (0, 0, 400, 600)
img_right_area = (400, 0, 800, 600)

img_left = img.crop(img_left_area)
img_right = img.crop(img_right_area)

img_left.show()
img_right.show()

Coordinate System

The Python Imaging Library uses a Cartesian pixel coordinate system, with (0,0) in the upper left corner. Note that the coordinates refer to the implied pixel corners; the centre of a pixel addressed as (0, 0) actually lies at (0.5, 0.5).

Coordinates are usually passed to the library as 2-tuples (x, y). Rectangles are represented as 4-tuples, with the upper left corner given first. For example, a rectangle covering all of an 800x600 pixel image is written as (0, 0, 800, 600).

This problem comes when you have copied some text from html or you have done modification in windows environment and trying to compile in Unix/Solaris environment.

The easy way to change the select, and update it is this.

// BY id
$('#select_element_selector').val('value').change();

another example:

//By tag
$('[name=selectxD]').val('value').change();

another example:

$("#select_element_selector").val('value').trigger('chosen:updated');

Use a .gitignore file. This allows you to ignore certain files. http://git-scm.com/docs/gitignore

Here's an example Eclipse one, which handles your classpath and project files: https://github.com/github/gitignore/blob/master/Global/Eclipse.gitignore

An addition to the solution by @Rafael Teles. The syntactic sugar Collectors.mapping does the same in one step:

//...
List<Employee> employees = persons.stream()
  .filter(p -> p.getLastName().equals("l1"))
  .collect(
    Collectors.mapping(
      p -> new Employee(p.getName(), p.getLastName(), 1000),
      Collectors.toList()));

If it is in the same directory you can use dirname $0:

#!/bin/bash

source $(dirname $0)/incl.sh

echo "The main script"

Without knowing your full application it is hard to say what the best way to approach the problem is, but a common technique is to use a header which starts with a fixed length field, which denotes the length of the rest of your message.

Assume that your header consist only of a 4 byte integer which denotes the length of the rest of your message. Then simply do the following.

// This assumes buffer is at least x bytes long,
// and that the socket is blocking.
void ReadXBytes(int socket, unsigned int x, void* buffer)
{
    int bytesRead = 0;
    int result;
    while (bytesRead < x)
    {
        result = read(socket, buffer + bytesRead, x - bytesRead);
        if (result < 1 )
        {
            // Throw your error.
        }

        bytesRead += result;
    }
}

Then later in the code

unsigned int length = 0;
char* buffer = 0;
// we assume that sizeof(length) will return 4 here.
ReadXBytes(socketFileDescriptor, sizeof(length), (void*)(&length));
buffer = new char[length];
ReadXBytes(socketFileDescriptor, length, (void*)buffer);

// Then process the data as needed.

delete [] buffer;

This makes a few assumptions:

• ints are the same size on the sender and receiver.
• Endianess is the same on both the sender and receiver.
• You have control of the protocol on both sides
• When you send a message you can calculate the length up front.

Since it is common to want to explicitly know the size of the integer you are sending across the network define them in a header file and use them explicitly such as:

// These typedefs will vary across different platforms
// such as linux, win32, OS/X etc, but the idea
// is that a Int8 is always 8 bits, and a UInt32 is always
// 32 bits regardless of the platform you are on.
// These vary from compiler to compiler, so you have to 
// look them up in the compiler documentation.
typedef char Int8;
typedef short int Int16;
typedef int Int32;

typedef unsigned char UInt8;
typedef unsigned short int UInt16;
typedef unsigned int UInt32;

This would change the above to:

UInt32 length = 0;
char* buffer = 0;

ReadXBytes(socketFileDescriptor, sizeof(length), (void*)(&length));
buffer = new char[length];
ReadXBytes(socketFileDescriptor, length, (void*)buffer);

// process

delete [] buffer;

I hope this helps.

If you use IIS Express via Visual Studio instead of the builtin ASP.net host, you can achieve this.

Try

cordova platform version

It will give you the following output

Installed platforms: android 3.5.1, ios 3.5.0

1. GROUP BY will aggregate records by the specified column which allows you to perform aggregation functions on non-grouped columns (such as SUM, COUNT, AVG, etc.). ORDER BY alters the order in which items are returned.
2. If you do SELECT IsActive, COUNT(*) FROM Customers GROUP BY IsActive you get a count of active and inactive customers. The group by aggregated the results based on the field you specified. If you do SELECT * FROM Customers ORDER BY Name then you get the result list sorted by the customer’s name.
3. If you GROUP, the results are not necessarily sorted; although in many cases they may come out in an intuitive order, that's not guaranteed by the GROUP clause. If you want your groups sorted, always use an explicitly ORDER BY after the GROUP BY.
4. Grouped data cannot be filtered by WHERE clause. Order data can be filtered by WHERE clause.

All of the instances installed should show up in the Services Snap-In in the Microsoft Management Console. To get the instance names, go to Start | Run | type Services.msc and look for all entries with "Sql Server (Instance Name)".

i used to do like this

inside view

<script type="text/javascript">

//will replace the '_transactionIds_' and '_payeeId_' 
var _addInvoiceUrl = '@(Html.Raw( Url.Action("PayableInvoiceMainEditor", "Payables", new { warehouseTransactionIds ="_transactionIds_",payeeId = "_payeeId_", payeeType="Vendor" })))';

on javascript file

var url = _addInvoiceUrl.replace('_transactionIds_', warehouseTransactionIds).replace('_payeeId_', payeeId);
        window.location.href = url;

in this way i can able to pass the parameter values on demand..

by using @Html.Raw, url will not get amp; for parameters

I agree with dfsq if all you want to do is show the button. If you want to switch between hiding and showing the button however, it is easier to use:

$("#buttonEditComment").toggleClass("hide");

Have a look at the ReadAsset.java from API samples that come with the SDK.

       try {
        InputStream is = getAssets().open("read_asset.txt");

        // We guarantee that the available method returns the total
        // size of the asset...  of course, this does mean that a single
        // asset can't be more than 2 gigs.
        int size = is.available();

        // Read the entire asset into a local byte buffer.
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        // Convert the buffer into a string.
        String text = new String(buffer);

        // Finally stick the string into the text view.
        TextView tv = (TextView)findViewById(R.id.text);
        tv.setText(text);
    } catch (IOException e) {
        // Should never happen!
        throw new RuntimeException(e);

In my case I run the tests and got error CS0006. It turned out that I run tests in Release mode. Switch to Debug mode fixed this error.

answer 1

1. Right click on your project in eclipse
2. go to maven -> Update Project

answer 2

simply press Alt+F5 after updating your pom.xml. This will build your project again and download all jar files

It is the CSS child selector. Example:

div > p selects all paragraphs that are direct children of div.

I had this same problem and it seemed to be related to using the same database connection for concurrent tasks. There might be some alternative solutions (maybe better), but I solved it by setting MaxConcurrentExecutables to 1.

You're searching for gc_maxlifetime, see http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime for a description.

Your session will last 1440 seconds which is 24 minutes (default).

Try:

extern int testlib(void);

Not sure if people are still looking for simple solutions to this, but you are able to run multiple instances of the "Collection Runner" in Postman. Just create a runner with some requests and click the "Run" button multiple times to bring up multiple instances.

You could hard code it.

From the documentation:

With one argument, return the natural logarithm of x (to base e).

With two arguments, return the logarithm of x to the given base, calculated as log(x)/log(base).

But the log₁₀ is made available as math.log10(), which does not resort to log division if possible.

You need to export the Customers Component not the CustomerList.

    CustomersList = withRouter(Customers);
    export default CustomersList;

From python 3.5: merging and summing

Thanks to @tokeinizer_fsj that told me in a comment that I didn't get completely the meaning of the question (I thought that add meant just adding keys that eventually where different in the two dictinaries and, instead, i meant that the common key values should be summed). So I added that loop before the merging, so that the second dictionary contains the sum of the common keys. The last dictionary will be the one whose values will last in the new dictionary that is the result of the merging of the two, so I thing the problem is solved. The solution is valid from python 3.5 and following versions.

a = {
    "a": 1,
    "b": 2,
    "c": 3
}

b = {
    "a": 2,
    "b": 3,
    "d": 5
}

# Python 3.5

for key in b:
    if key in a:
        b[key] = b[key] + a[key]

c = {**a, **b}
print(c)

>>> c
{'a': 3, 'b': 5, 'c': 3, 'd': 5}

Reusable code

a = {'a': 1, 'b': 2, 'c': 3}
b = {'b': 3, 'c': 4, 'd': 5}


def mergsum(a, b):
    for k in b:
        if k in a:
            b[k] = b[k] + a[k]
    c = {**a, **b}
    return c


print(mergsum(a, b))

If there are no performance gains using a join, then I prefer Common Table Expressions (CTEs) for readability:

WITH subquery AS (
    SELECT address_id, customer, address, partn
    FROM  /* big hairy SQL */ ...
)
UPDATE dummy
SET customer = subquery.customer,
    address  = subquery.address,
    partn    = subquery.partn
FROM subquery
WHERE dummy.address_id = subquery.address_id;

IMHO a bit more modern.

You could use bind method

for (var i = 1, j = 1; i <= 3; i++, j++) {
    setTimeout(function() {
        alert(this);
    }.bind(i), j * 100);
}

My virtualwrapper.sh was in

This is probably because I installed virtualenvwrapper locally, using the --user flag...

In my case, I had an input variable setter using the ViewChild, and the ViewChild was inside of an *ngIf directive, so the setter was trying to access it before the *ngIf rendered (it would work fine without the *ngIf, but would not work if it was always set to true with *ngIf="true").

To solve, I used Rxjs to make sure any reference to the ViewChild waited until the view was initiated. First, create a Subject that completes when after view init.

export class MyComponent implements AfterViewInit {
  private _viewInitWaiter$ = new Subject();

  ngAfterViewInit(): void {
    this._viewInitWaiter$.complete();
  }
}

Then, create a function that takes and executes a lambda after the subject completes.

private _executeAfterViewInit(func: () => any): any {
  this._viewInitWaiter$.subscribe(null, null, () => {
    return func();
  })
}

Finally, make sure references to the ViewChild use this function.

@Input()
set myInput(val: any) {
    this._executeAfterViewInit(() => {
        const viewChildProperty = this.viewChild.someProperty;
        ...
    });
}

@ViewChild('viewChildRefName', {read: MyViewChildComponent}) viewChild: MyViewChildComponent;

Why does C# have both 'ref' and 'out'?

The caller of a method which takes an out parameter is not required to assign to the variable passed as the out parameter prior to the call; however, the callee is required to assign to the out parameter before returning.

In contrast ref parameters are considered initially assigned by the caller. As such, the callee is not required to assign to the ref parameter before use. Ref parameters are passed both into and out of a method.

So, out means out, while ref is for in and out.

These correspond closely to the [out] and [in,out] parameters of COM interfaces, the advantages of out parameters being that callers need not pass a pre-allocated object in cases where it is not needed by the method being called - this avoids both the cost of allocation, and any cost that might be associated with marshaling (more likely with COM, but not uncommon in .NET).

jQuerify is the perfect extension to embed jQuery into Chrome Console and is as simple as you can imagine. This extension also indicates if jQuery has been already embedded into a page.

This extension is used to embed jQuery into any page you want. It allows to use jQuery in the console shell (You can invoke Chrome console by Ctrl + Shift + j".).

To embed jQuery into the selected tab click on extension button.

Have you tried creating a windows shortcut for sql plus and set the working directory?

Take a look at this JQuery plugin:

http://fixedheadertable.com

It adds vertical (fixed header row) or horizontal (fixed first column) scrolling to an existing HTML table. There is a demo you can check for both cases of scrolling.

git add .
git reset

git add . will stage ALL the files telling git that you have resolved the conflict

git reset will unstage ALL the staged files without creating a commit

GIT uses colored output by default but on some system like as CentOS it is not enabled . You can enable it like this

git config --global color.ui  true 
git config --global color.ui  false 
git config --global color.ui  auto 

You can choose your required command from here .

Here --global is optional to apply action for every repository in your system . If you want to apply coloring for current repository only then you can do something like this -

 git config color.ui  true 

you can use RabbitMQ API to get count or messages :

/api/queues/vhost/name/get

Get messages from a queue. (This is not an HTTP GET as it will alter the state of the queue.) You should post a body looking like:

{"count":5,"requeue":true,"encoding":"auto","truncate":50000}

count controls the maximum number of messages to get. You may get fewer messages than this if the queue cannot immediately provide them.

requeue determines whether the messages will be removed from the queue. If requeue is true they will be requeued - but their redelivered flag will be set. encoding must be either "auto" (in which case the payload will be returned as a string if it is valid UTF-8, and base64 encoded otherwise), or "base64" (in which case the payload will always be base64 encoded). If truncate is present it will truncate the message payload if it is larger than the size given (in bytes). truncate is optional; all other keys are mandatory.

Please note that the publish / get paths in the HTTP API are intended for injecting test messages, diagnostics etc - they do not implement reliable delivery and so should be treated as a sysadmin's tool rather than a general API for messaging.

To get the value of my drop down box on page load, I use

document.addEventListener('DOMContentLoaded',fnName);

Hope this helps some one.

This one solved the problem for me on MAC:

  brew install graphviz

Unfortunately, most of the articles on state machines are written for C++ or other languages that have direct support for polymorphism as it's nice to model the states in an FSM implementation as classes that derive from an abstract state class.

However, it's pretty easy to implement state machines in C using either switch statements to dispatch events to states (for simple FSMs, they pretty much code right up) or using tables to map events to state transitions.

There are a couple of simple, but decent articles on a basic framework for state machines in C here:

• http://www.gedan.net/2008/09/08/finite-state-machine-matrix-style-c-implementation/
• http://www.gedan.net/2009/03/18/finite-state-machine-matrix-style-c-implementation-function-pointers-addon/

Edit: Site "under maintenance", web archive links:

• http://web.archive.org/web/20160517005245/http://www.gedan.net/2008/09/08/finite-state-machine-matrix-style-c-implementation
• http://web.archive.org/web/20160808120758/http://www.gedan.net/2009/03/18/finite-state-machine-matrix-style-c-implementation-function-pointers-addon/

switch statement-based state machines often use a set of macros to 'hide' the mechanics of the switch statement (or use a set of if/then/else statements instead of a switch) and make what amounts to a "FSM language" for describing the state machine in C source. I personally prefer the table-based approach, but these certainly have merit, are widely used, and can be effective especially for simpler FSMs.

One such framework is outlined by Steve Rabin in "Game Programming Gems" Chapter 3.0 (Designing a General Robust AI Engine).

A similar set of macros is discussed here:

• https://contrarymotion.net/2008/02/12/some-code-snippets-for-a-simple-c-state-machine/

If you're also interested in C++ state machine implementations there's a lot more that can be found. I'll post pointers if you're interested.

It is better to do this on the design surface (Visual Studio 2012 is shown but can be done in other versions) first before calculating any maths when editing an SSRS document.

Below the following numbers in red circles that map to these following steps:

1. In the design surface, sometimes the editor will create a page which is larger than the actual controls; hence the ghost area being printed.
2. Resize to the controls. Visually look at the width/height and see if you can't bring in the page on the design surface to size it to the space actually needed by the controls and no more.
3. Then try to create a PDF and see if that fixes it.
4. If #3 does not resolve the issue, then there are controls requiring too much of the actual page size and going over in either length/width. So one will need to make the size of the controls smaller to accommodate a smaller page size.

Also in some circumstances one can just change a property of the report page by setting ConsumeContainerWhitespace to true to automatically consume the spaces.

A three-liner to combine or merge two dictionaries:

dest = {}
dest.update(orig)
dest.update(extra)

This creates a new dictionary dest without modifying orig and extra.

Note: If a key has different values in orig and extra, then extra overrides orig.

Due to the exposed fact that Class literals doesn't have generic type information, I think you should assume that it will be impossible to get rid of all the warnings. In a way, using Class<Something> is the same as using a collection without specifying the generic type. The best I could come out with was:

private <C extends A<C>> List<C> getList(Class<C> cls) {
    List<C> res = new ArrayList<C>();
    // "snip"... some stuff happening in here, using cls
    return res;
}

public <C extends A<C>> List<A<C>> getList() {
    return getList(A.class);
}

It provides rolled-up data without rolling up

i.e. Suppose I want to return the relative position of sales region

Using PARTITION BY, I can return the sales amount for a given region and the MAX amount across all sales regions in the same row.

This does mean you will have repeating data, but it may suit the end consumer in the sense that data has been aggregated but no data has been lost - as would be the case with GROUP BY.

lastInsertId() only work after the INSERT query.

Correct:

$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass) 
                              VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();

Incorrect:

$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0

for full url use

$('#imageContainerId').prop('src')

for relative image url use

$('#imageContainerId').attr('src')

function showImgUrl(){_x000D_
  console.log('for full image url ' + $('#imageId').prop('src') );_x000D_
  console.log('for relative image url ' + $('#imageId').attr('src'));_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

Try this :

 public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            var res = Find(html);
        }

        public static List<LinkItem> Find(string file)
        {
            List<LinkItem> list = new List<LinkItem>();

            // 1.
            // Find all matches in file.
            MatchCollection m1 = Regex.Matches(file, @"(<a.*?>.*?</a>)",
                RegexOptions.Singleline);

            // 2.
            // Loop over each match.
            foreach (Match m in m1)
            {
                string value = m.Groups[1].Value;
                LinkItem i = new LinkItem();

                // 3.
                // Get href attribute.
                Match m2 = Regex.Match(value, @"href=\""(.*?)\""",
                RegexOptions.Singleline);
                if (m2.Success)
                {
                    i.Href = m2.Groups[1].Value;
                }

                // 4.
                // Remove inner tags from text.
                string t = Regex.Replace(value, @"\s*<.*?>\s*", "",
                RegexOptions.Singleline);
                i.Text = t;

                list.Add(i);
            }
            return list;
        }

        public struct LinkItem
        {
            public string Href;
            public string Text;

            public override string ToString()
            {
                return Href + "\n\t" + Text;
            }
        }

    }  

Input:

  string html = "<a href=\"www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a> 2.<a href=\"http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a> "; 

Result:

[0] = {www.aaa.xx/xx.zz?id=xxxx&name=xxxx}
[1] = {http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx}

C# Scraping HTML Links

Scraping HTML extracts important page elements. It has many legal uses for webmasters and ASP.NET developers. With the Regex type and WebClient, we implement screen scraping for HTML.

Edited

Another easy way:you can use a web browser control for getting href from tag a,like this:(see my example)

 public Form1()
        {
            InitializeComponent();
            webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            webBrowser1.DocumentText = "<a href=\"www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"https://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"www.aaa.xx/xx.zz/xxx\" ....></a>";
        }

        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            List<string> href = new List<string>();
            foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("a"))
            {
                href.Add(el.GetAttribute("href"));
            }
        }

A key is just a normal index. A way over simplification is to think of it like a card catalog at a library. It points MySQL in the right direction.

A unique key is also used for improved searching speed, but it has the constraint that there can be no duplicated items (there are no two x and y where x is not y and x == y).

The manual explains it as follows:

A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. This constraint does not apply to NULL values except for the BDB storage engine. For other engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL. If you specify a prefix value for a column in a UNIQUE index, the column values must be unique within the prefix.

A primary key is a 'special' unique key. It basically is a unique key, except that it's used to identify something.

The manual explains how indexes are used in general: here.

In MSSQL, the concepts are similar. There are indexes, unique constraints and primary keys.

Untested, but I believe the MSSQL equivalent is:

CREATE TABLE tmp (
  id int NOT NULL PRIMARY KEY IDENTITY,
  uid varchar(255) NOT NULL CONSTRAINT uid_unique UNIQUE,
  name varchar(255) NOT NULL,
  tag int NOT NULL DEFAULT 0,
  description varchar(255),
);

CREATE INDEX idx_name ON tmp (name);
CREATE INDEX idx_tag ON tmp (tag);

Edit: the code above is tested to be correct; however, I suspect that there's a much better syntax for doing it. Been a while since I've used SQL server, and apparently I've forgotten quite a bit :).

You can use the Math.Max method to return the maximum of two numbers, e.g. for int:

int maximum = Math.Max(number1, Math.Max(number2, number3))

There ist also the Max() method from LINQ which you can use on any IEnumerable.

The offset under Windows 10 is 0x022C (x64-bit-Application) and 0x0160 (x32-bit-Application):

public static int GetNativeThreadId(Thread thread)
{
    var f = typeof(Thread).GetField("DONT_USE_InternalThread",
        BindingFlags.GetField | BindingFlags.NonPublic | BindingFlags.Instance);

    var pInternalThread = (IntPtr)f.GetValue(thread);
    var nativeId = Marshal.ReadInt32(pInternalThread, (IntPtr.Size == 8) ? 0x022C : 0x0160); // found by analyzing the memory
    return nativeId;
}

Update

I later found that, there is an official way to see all the routes, by going to http://localhost:3000/rails/info/routes. Official docs: https://guides.rubyonrails.org/routing.html#listing-existing-routes

Though, it may be late, But I love the error page which displays all the routes. I usually try to go at /routes (or some bogus) path directly from the browser. Rails server automatically gives me a routing error page as well as all the routes and paths defined. That was very helpful :)

So, Just go to http://localhost:3000/routes

If "sudo apt-get install php-curl" command doesnt work and display error We should run this code before install curl.

• step1 - sudo add-apt-repository ppa:ondrej/php
• step2 - sudo apt-get update
• step3 - sudo apt-get install php-curl
• step4 - sudo service apache2 restart

select to_char(to_date('1/21/2000','mm/dd/yyyy'),'dd-mm-yyyy') from dual

Use the splice method.

ArrayName.splice(indexValueOfArray,1);

This removes 1 item from the array starting at indexValueOfArray.

You can suppress the space by printing an empty string to stdout between the print statements.

>>> import sys
>>> for i in range(20):
...   print 'a',
...   sys.stdout.write('')
... 
aaaaaaaaaaaaaaaaaaaa

However, a cleaner solution is to first build the entire string you'd like to print and then output it with a single print statement.

You may use scanf for this purpose with a little trick. Actually, you should allow user input until user hits Enter (\n). This will consider every character, including space. Here is example:

int main()
{
  char string[100], c;
  int i;
  printf("Enter the string: ");
  scanf("%s", string);
  i = strlen(string);      // length of user input till first space
  do
  {
    scanf("%c", &c);
    string[i++] = c;       // reading characters after first space (including it)
  } while (c != '\n');     // until user hits Enter
  string[i - 1] = 0;       // string terminating
return 0;
}

How this works? When user inputs characters from standard input, they will be stored in string variable until first blank space. After that, rest of entry will remain in input stream, and wait for next scanf. Next, we have a for loop that takes char by char from input stream (till \n) and apends them to end of string variable, thus forming a complete string same as user input from keyboard.

Hope this will help someone!

for me it is daterangepicker worked by this :

     $('#host1field').daterangepicker({
                   locale: {
                            format: 'DD/MM/YYYY'
                            }
                 });

Have a look at the EditorConfig plugin.

By using the plugin you can have settings specific for various projects. Visual Studio Code also has IntelliSense built-in for .editorconfig files.

Your code like this is incorrect as foreach only for single array:

<?php
        $codes = array('tn','us','fr');
        $names = array('Tunisia','United States','France');

        foreach( $codes as $code and $names as $name ) {
            echo '<option value="' . $code . '">' . $name . '</option>';
            }
?>

Alternative, Change to this:

<?php
        $codes = array('tn','us','fr');
        $names = array('Tunisia','United States','France');
        $count = 0;

        foreach($codes as $code) {
             echo '<option value="' . $code . '">' . $names[count] . '</option>';
             $count++;
        }

?>

The modulo operator evaluates to the remainder of the division of the two integer operands. Here are a few examples:

23 % 10 evaluates to 3 (because 23/10 is 2 with a remainder of 3)
50 % 50 evaluates to 0 (50/50 is 1 with a remainder of 0)
9 % 100 evaluates to 9 (9/100 is 0 with a remainder of 9)

The easiest solution I found for this so far is the Non-Sucking Service Manager

Usage would be

nssm install <servicename> "C:\Program Files\Java\jre7\java.exe" "-jar <path-to-jar-file>"

You can use ng-class to add conditional classes.

HTML

<button id="button1" ng-click="alpha = true" ng-class="{alpha: alpha}">Button</button>

In your controller (to make sure the class is not shown by default)

$scope.alpha = false;

Now, when you click the button, the $scope.alpha variable is updated and ng-class will add the 'alpha' class to your button.

How about using David Cramer's solution:

http://cramer.io/2010/12/06/tracking-changes-to-fields-in-django/

I've had success using it like this:

@track_data('name')
class Mode(models.Model):
    name = models.CharField(max_length=5)
    mode = models.CharField(max_length=5)

    def save(self, *args, **kwargs):
        if self.has_changed('name'):
            print 'name changed'

    # OR #

    @classmethod
    def post_save(cls, sender, instance, created, **kwargs):
        if instance.has_changed('name'):
            print "Hooray!"

You Need to take same height and width

and simply use the border-radius:360px;

I don't know if this helps but I just installed Server 2008 Express and was disappointed when I couldn't find the query analyzer but I was able to use the command line 'sqlcmd' to access my server. It is a pain to use but it works. You can write your code in a text file then import it using the sqlcmd command. You also have to end your query with a new line and type the word 'go'.

Example of query file named test.sql:
use master;
select name, crdate from sysdatabases where xtype='u' order by crdate desc;
go

Example of sqlcmd:
sqlcmd -S %computername%\RLH -d play -i "test.sql" -o outfile.sql & notepad outfile.sql

Or for other code equivalents try:

£
£

It's a little memory-inefficient but if you're using the data anyway, I use this frequently:

$rows = $q->fetchAll();
$num_rows = count($rows);

You can use .text-reset class to reset the color from default blue to anything you want. Hopefully this is helpful.

Source: https://getbootstrap.com/docs/4.5/utilities/text/#reset-color

Assuming id is the primary key of table :

SELECT * FROM table WHERE id BETWEEN 10 AND 50

For first 20 results

SELECT * FROM table order by id limit 20;

There are several libraries. Here are two examples:

❐ Apache Commons Lang

Apache Commons Lang includes a special class to escape or unescape strings (CSV, EcmaScript, HTML, Java, Json, XML): org.apache.commons.lang3.StringEscapeUtils.

• Escape to CSV

  String escaped = StringEscapeUtils
      .escapeCsv("I said \"Hey, I am 5'10\".\""); // I said "Hey, I am 5'10"."
  
  System.out.println(escaped); // "I said ""Hey, I am 5'10""."""
  

• Unescape from CSV

  String unescaped = StringEscapeUtils
      .unescapeCsv("\"I said \"\"Hey, I am 5'10\"\".\"\"\""); // "I said ""Hey, I am 5'10""."""
  
  System.out.println(unescaped); // I said "Hey, I am 5'10"."
  

_{* You can download it from here.}

❐ OpenCSV

If you use OpenCSV, you will not need to worry about escape or unescape, only for write or read the content.

• Writing file:

  FileOutputStream fos = new FileOutputStream("awesomefile.csv"); 
  OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");
  CSVWriter writer = new CSVWriter(osw);
  ...
  String[] row = {
      "123", 
      "John", 
      "Smith", 
      "39", 
      "I said \"Hey, I am 5'10\".\""
  };
  writer.writeNext(row);
  ...
  writer.close();
  osw.close();
  os.close();
  

• Reading file:

  FileInputStream fis = new FileInputStream("awesomefile.csv"); 
  InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
  CSVReader reader = new CSVReader(isr);
  
  for (String[] row; (row = reader.readNext()) != null;) {
      System.out.println(Arrays.toString(row));
  }
  
  reader.close();
  isr.close();
  fis.close();

Go to the Ant website and download. This way, you have a copy of Ant outside of Eclipse. I recommend to put it under the C:\ant directory. This way, it doesn't have any spaces in the directory names. In your System Control Panel, set the Environment Variable ANT_HOME to this directory, then pre-pend to the System PATHvariable, %ANT_HOME%\bin. This way, you don't have to put in the whole directory name.

Assuming you did the above, try this:

C:\> cd \Silk4J\Automation\iControlSilk4J
C:\Silk4J\Automation\iControlSilk4J> ant -d build

This will do several things:

• It will eliminate the possibility that the problem is with Eclipe's version of Ant.
• It is way easier to type
• Since you're executing the build.xml in the directory where it exists, you don't end up with the possibility that your Ant build can't locate a particular directory.

The -d will print out a lot of output, so you might want to capture it, or set your terminal buffer to something like 99999, and run cls first to clear out the buffer. This way, you'll capture all of the output from the beginning in the terminal buffer.

Let's see how Ant should be executing. You didn't specify any targets to execute, so Ant should be taking the default build target. Here it is:

<target depends="build-subprojects,build-project" name="build"/>

The build target does nothing itself. However, it depends upon two other targets, so these will be called first:

The first target is build-subprojects:

<target name="build-subprojects"/>

This does nothing at all. It doesn't even have a dependency.

The next target specified is build-project does have code:

<target depends="init" name="build-project">

This target does contain tasks, and some dependent targets. Before build-project executes, it will first run the init target:

<target name="init">
    <mkdir dir="bin"/>
    <copy includeemptydirs="false" todir="bin">
        <fileset dir="src">
            <exclude name="**/*.java"/>
        </fileset>
    </copy>
</target>

This target creates a directory called bin, then copies all files under the src tree with the suffix *.java over to the bin directory. The includeemptydirs mean that directories without non-java code will not be created.

Ant uses a scheme to do minimal work. For example, if the bin directory is created, the <mkdir/> task is not executed. Also, if a file was previously copied, or there are no non-Java files in your src directory tree, the <copy/> task won't run. However, the init target will still be executed.

Next, we go back to our previous build-project target:

<target depends="init" name="build-project">
    <echo message="${ant.project.name}: ${ant.file}"/>
    <javac debug="true" debuglevel="${debuglevel}" destdir="bin" source="${source}" target="${target}">
        <src path="src"/>
        <classpath refid="iControlSilk4J.classpath"/>
    </javac>
</target>

Look at this line:

<echo message="${ant.project.name}: ${ant.file}"/>

That should have always executed. Did your output print:

[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

Maybe you didn't realize that was from your build.

After that, it runs the <javac/> task. That is, if there's any files to actually compile. Again, Ant tries to avoid work it doesn't have to do. If all of the *.java files have previously been compiled, the <javac/> task won't execute.

And, that's the end of the build. Your build might not have done anything simply because there was nothing to do. You can try running the clean task, and then build:

C:\Silk4J\Automation\iControlSilk4J> ant -d clean build

However, Ant usually prints the target being executed. You should have seen this:

init:

build-subprojects:

build-projects:

    [echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

build:

Build Successful

Note that the targets are all printed out in order they're executed, and the tasks are printed out as they are executed. However, if there's nothing to compile, or nothing to copy, then you won't see these tasks being executed. Does this look like your output? If so, it could be there's nothing to do.

• If the bin directory already exists, <mkdir/> isn't going to execute.
• If there are no non-Java files in src, or they have already been copied into bin, the <copy/> task won't execute.
• If there are no Java file in your src directory, or they have already been compiled, the <java/> task won't run.

If you look at the output from the -d debug, you'll see Ant looking at a task, then explaining why a particular task wasn't executed. Plus, the debug option will explain how Ant decides what tasks to execute.

See if that helps.

At a command prompt type:

python -V

Or if you have pyenv:

pyenv versions

You can do this with JavaScript.

document.getElementById('foo').height = document.getElementById('foo').contentWindow.document.body.scrollHeight + "px";

if your button is inside your form class:

buttonOk.Click += new EventHandler(your_click_method);

(might not be exactly EventHandler)

and in your click method:

this.Close();

If you need to show a message box:

MessageBox.Show("test");

You can customize a project's Git config by changing the repository specific configuration file (i.e. /path/to/repo/.git/config). BTW, git config writes to this file by default:

cd /path/to/repo
git config user.name 'John Doe'  # sets user.name locally for the repo

I prefer to create separate profiles for different projects (e.g. in ~/.gitconfig.d/) and then include them in the repository's config file:

cd /path/to/repo
git config include.path '~/.gitconfig.d/myproject.conf'

This works well if you need to use the same set of options in multiple repos that belong to a single project. You can also set up shell aliases or a custom Git command to manipulate the profiles.

In my case, it started hapenning after I updated to Android Studio 1.2. To fix it I just had to remove "\bin" from my JAVA_HOME variable.

Looking at man 3 printf on Linux, OS X, and OpenBSD all show support for %z for size_t and %t for ptrdiff_t (for C99), but none of those mention off_t. Suggestions in the wild usually offer up the %u conversion for off_t, which is "correct enough" as far as I can tell (both unsigned int and off_t vary identically between 64-bit and 32-bit systems).

add plt.figure(figsize=(16,5)) before the sns.heatmap and play around with the figsize numbers till you get the desired size

...

plt.figure(figsize = (16,5))

ax = sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5)

The context classes for badge are indeed removed from Bootstrap 3, so you'd have to add some custom CSS to create the same effect like...

.badge-important{background-color:#b94a48;}

Bootply

The benefit is that the output of previous function is used. You do not need to repeat where the data source comes from, for example.

Another SIMPLE option is to delete the node_modules and package-lock.json

rm -rf node_modules
rm -rf package-lock.json

After this you can try reinstalling the npm packages

C:\\Users\\expoperialed\\Desktop\\Python This syntax worked for me.
