In my case the RDLC files work with resource files (.resx), I had this error because I hadn't created the correspondent resx file for my rdlc report.

My solution was add the file .resx inside the App_LocalResources in this way:

\rep
\rep\myreport.rdlc
\rep\App_LocalResources\myreport.rdlc.resx

giammin's solution is partially incorrect. You SHOULD NOT remove that entire PropertyGroup from your solution. If you do, MSBuild's "DeployTarget=Package" feature will stop working. This feature relies on the "VSToolsPath" being set.

<PropertyGroup>
  <!-- VisualStudioVersion is incompatible with later versions of Visual Studio.  Removing. -->
  <!-- <VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion> -->
  <!-- VSToolsPath is required by MSBuild for features like "DeployTarget=Package" -->
  <VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
</PropertyGroup>
...
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />

I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.

set codedirectory=C:\Users\code
for /r  %codedirectory% %%i in (*.c) do 
( some GCC commands )

Maven is a build tool. Along with Ant or Gradle are Javas tools for building.
If you are a newbie in Java though just build using your IDE since Maven has a steep learning curve.

Since the count is the intended final value, in your query pass

$this->db->distinct();
$this->db->select('accessid');
$this->db->where('record', $record); 
$query = $this->db->get()->result_array();
return count($query);

The count the retuned value

Check out the PHP cURL functions. They should do what you want.

Or if you just want a simple URL GET then:

$lines = file('http://www.example.com/');

You just need to enable the tooltip:

$('some id or class that you add to the above a tag').popover({
    trigger: "hover" 
})

Complex answers everywhere!

Just use the following

git rm -r --cached .

It will remove the files you are trying to ignore from the origin and not from the master on your computer!

After that just commit and push!

This is the shared preferences code i use successfully, Refer this link:

  public class MainActivity extends Activity {

private static final int RESULT_SETTINGS = 1;

super.onCreate(savedInstanceState);

 button = (Button) findViewById(R.id.btnoptions);


setContentView(R.layout.activity_main);

  // showUserSettings();

HAPPY CODING!

It means parent/child

example:

html>body

that's saying that body is a child of html

Check out: Selectors

For the tags, you should be able to just set the content with .text() instead of .html().

Example: http://jsfiddle.net/Phf4u/1/

var textarea = $('textarea').val().replace(/<br\s?\/?>/, '\n');

$("#output").text(textarea);

...or if you just wanted to remove the <br> elements, you could get rid of the .replace(), and temporarily make them DOM elements.

Example: http://jsfiddle.net/Phf4u/2/

var textarea = $('textarea').val();

textarea = $('<div>').html(textarea).find('br').remove().end().html();

$("#output").text(textarea);

The above answers tell how to get the position using different API, onScroll, onMomentumScrollEnd etc; If you want to know the page index, you can calculate it using the offset value.

 <ScrollView 
    pagingEnabled={true}
    onMomentumScrollEnd={this._onMomentumScrollEnd}>
    {pages}
 </ScrollView> 

  _onMomentumScrollEnd = ({ nativeEvent }: any) => {
   // the current offset, {x: number, y: number} 
   const position = nativeEvent.contentOffset; 
   // page index 
   const index = Math.round(nativeEvent.contentOffset.x / PAGE_WIDTH);

   if (index !== this.state.currentIndex) {
     // onPageDidChanged
   }
 };

In iOS, the relationship between ScrollView and the visible region is as follow:

ref: https://www.objc.io/issues/3-views/scroll-view/

Big-O is to little-o as = is to <. Big-O is an inclusive upper bound, while little-o is a strict upper bound.

For example, the function f(n) = 3n is:

• in O(n²), o(n²), and O(n)
• not in O(lg n), o(lg n), or o(n)

Analogously, the number 1 is:

• = 2, < 2, and = 1
• not = 0, < 0, or < 1

Here's a table, showing the general idea:

(Note: the table is a good guide but its limit definition should be in terms of the superior limit instead of the normal limit. For example, 3 + (n mod 2) oscillates between 3 and 4 forever. It's in O(1) despite not having a normal limit, because it still has a lim sup: 4.)

I recommend memorizing how the Big-O notation converts to asymptotic comparisons. The comparisons are easier to remember, but less flexible because you can't say things like n^O(1) = P.

Here is a good article from Microsoft http://www.iis.net/learn/troubleshoot/security-issues/troubleshooting-forms-authentication that covers various cases and scenarios.

This error indicates that the two tables have the 1 or more column names that have the same column name. The error message translates to: "I can see the same column in both tables but you haven't told me to rename either before bringing one of them in"

You either want to delete one of the columns before bringing it in from the other on using del df['column name'], or use lsuffix to re-write the original column, or rsuffix to rename the one that is being brought it.

df_a.join(df_b, on='mukey', how='left', lsuffix='_left', rsuffix='_right')

As stats on iOS usage, indicating that iOS 9.0-9.2.x usage is currently at 0.17%. If these numbers are truly indicative of global use of these versions, then it’s even more likely to be safe to remove shrink-to-fit from your viewport meta tag.

After 9.2.x. IOS remove this tag check on its' browser.

You can check this page https://www.scottohara.me/blog/2018/12/11/shrink-to-fit.html

Try \r\n where \r is carriage return. Also ensure that your output do not have new line, because debugger can show you special characters in form of \n, \r, \t etc.

Have you tried JQuery? Vanilla javascript can be tough. Try using this:

$('.container-element').add('<div>Insert Div Content</div>');

.container-element is a JQuery selector that marks the element with the class "container-element" (presumably the parent element in which you want to insert your divs). Then the add() function inserts HTML into the container-element.

Push annotated tags, keep lightweight local

man git-tag says:

Annotated tags are meant for release while lightweight tags are meant for private or temporary object labels.

And certain behaviors do differentiate between them in ways that this recommendation is useful e.g.:

• annotated tags can contain a message, creator, and date different than the commit they point to. So you could use them to describe a release without making a release commit.

  Lightweight tags don't have that extra information, and don't need it, since you are only going to use it yourself to develop.

• git push --follow-tags will only push annotated tags
• git describe without command line options only sees annotated tags

Internals differences

• both lightweight and annotated tags are a file under .git/refs/tags that contains a SHA-1

• for lightweight tags, the SHA-1 points directly to a commit:

  git tag light
  cat .git/refs/tags/light
  

  prints the same as the HEAD's SHA-1.

  So no wonder they cannot contain any other metadata.

• annotated tags point to a tag object in the object database.

  git tag -as -m msg annot
  cat .git/refs/tags/annot
  

  contains the SHA of the annotated tag object:

  c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  and then we can get its content with:

  git cat-file -p c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  sample output:

  object 4284c41353e51a07e4ed4192ad2e9eaada9c059f
  type commit
  tag annot
  tagger Ciro Santilli <[email protected]> 1411478848 +0200
  
  msg
  -----BEGIN PGP SIGNATURE-----
  Version: GnuPG v1.4.11 (GNU/Linux)
  
  <YOUR PGP SIGNATURE>
  -----END PGP SIGNAT
  

  And this is how it contains extra metadata. As we can see from the output, the metadata fields are:

  • the object it points to
  • the type of object it points to. Yes, tag objects can point to any other type of object like blobs, not just commits.
  • the name of the tag
  • tagger identity and timestamp
  • message. Note how the PGP signature is just appended to the message

  A more detailed analysis of the format is present at: What is the format of a git tag object and how to calculate its SHA?

Bonuses

• Determine if a tag is annotated:

  git cat-file -t tag
  

  Outputs

  • commit for lightweight, since there is no tag object, it points directly to the commit
  • tag for annotated, since there is a tag object in that case

• List only lightweight tags: How can I list all lightweight tags?

Are you sure that its not one query per line? Your text editor may be wrapping lines, but in reality each query may be on a single line.

At any rate, olle's method seems best. If you have reasons to run queries one at time, you should be able to read in your file line by line, then use the semicolon at the end of each query to delimit. You're much better off reading in a file line by line than trying to split an enormous string, as it will be much kinder to your server's memory. Example:

$query  = '';
$handle = @fopen("/sqlfile.sql", "r");

if ($handle) {
    while (!feof($handle)) {
        $query.= fgets($handle, 4096);

        if (substr(rtrim($query), -1) === ';') {
            // ...run your query, then unset the string
            $query = '';
        }
    }

    fclose($handle);
}

Obviously, you'll need to consider transactions and the rest if you're running a whole lot of queries in a batch, but it's probably not a big deal for a new-install script.

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

The easier is add [0] - select first value of list with one element:

dfb = df[df['A']==5].index.values.astype(int)[0]
dfbb = df[df['A']==8].index.values.astype(int)[0]

dfb = int(df[df['A']==5].index[0])
dfbb = int(df[df['A']==8].index[0])

But if possible some values not match, error is raised, because first value not exist.

Solution is use next with iter for get default parameetr if values not matched:

dfb = next(iter(df[df['A']==5].index), 'no match')
print (dfb)
4

dfb = next(iter(df[df['A']==50].index), 'no match')
print (dfb)
no match

Then it seems need substract 1:

print (df.loc[dfb:dfbb-1,'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

Another solution with boolean indexing or query:

print (df[(df['A'] >= 5) & (df['A'] < 8)])
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

print (df.loc[(df['A'] >= 5) & (df['A'] < 8), 'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

print (df.query('A >= 5 and A < 8'))
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

Everybody jumped on this one!!! I too made a fiddle:

RobAgar gets a point for pointing out white-space:nowrap first.

Couple of things here, you need overflow: hidden if you don't want to see the extra characters poking out into your layout.

Also, as mentioned, you could use white-space: pre (see EnderMB) keeping in mind that pre will not collapse white space whereas white-space: nowrap will.

OK, got it working. Turns out that an NTFS volume where the DB files were located got heavily fragmented. Stopped SQL Server, defragmented the whole thing and all it was fine ever since.

In addition to all the previous answers, I would like to tell about the different behavior of gather() and wait() in case they are cancelled.

Gather cancellation

If gather() is cancelled, all submitted awaitables (that have not completed yet) are also cancelled.

Wait cancellation

If the wait() task is cancelled, it simply throws an CancelledError and the waited tasks remain intact.

Simple example:

import asyncio


async def task(arg):
    await asyncio.sleep(5)
    return arg


async def cancel_waiting_task(work_task, waiting_task):
    await asyncio.sleep(2)
    waiting_task.cancel()
    try:
        await waiting_task
        print("Waiting done")
    except asyncio.CancelledError:
        print("Waiting task cancelled")

    try:
        res = await work_task
        print(f"Work result: {res}")
    except asyncio.CancelledError:
        print("Work task cancelled")


async def main():
    work_task = asyncio.create_task(task("done"))
    waiting = asyncio.create_task(asyncio.wait({work_task}))
    await cancel_waiting_task(work_task, waiting)

    work_task = asyncio.create_task(task("done"))
    waiting = asyncio.gather(work_task)
    await cancel_waiting_task(work_task, waiting)


asyncio.run(main())

Output:

asyncio.wait()
Waiting task cancelled
Work result: done
----------------
asyncio.gather()
Waiting task cancelled
Work task cancelled

Sometimes it becomes necessary to combine wait() and gather() functionality. For example, we want to wait for the completion of at least one task and cancel the rest pending tasks after that, and if the waiting itself was canceled, then also cancel all pending tasks.

As real examples, let's say we have a disconnect event and a work task. And we want to wait for the results of the work task, but if the connection was lost, then cancel it. Or we will make several parallel requests, but upon completion of at least one response, cancel all others.

It could be done this way:

import asyncio
from typing import Optional, Tuple, Set


async def wait_any(
        tasks: Set[asyncio.Future], *, timeout: Optional[int] = None,
) -> Tuple[Set[asyncio.Future], Set[asyncio.Future]]:
    tasks_to_cancel: Set[asyncio.Future] = set()
    try:
        done, tasks_to_cancel = await asyncio.wait(
            tasks, timeout=timeout, return_when=asyncio.FIRST_COMPLETED
        )
        return done, tasks_to_cancel
    except asyncio.CancelledError:
        tasks_to_cancel = tasks
        raise
    finally:
        for task in tasks_to_cancel:
            task.cancel()


async def task():
    await asyncio.sleep(5)


async def cancel_waiting_task(work_task, waiting_task):
    await asyncio.sleep(2)
    waiting_task.cancel()
    try:
        await waiting_task
        print("Waiting done")
    except asyncio.CancelledError:
        print("Waiting task cancelled")

    try:
        res = await work_task
        print(f"Work result: {res}")
    except asyncio.CancelledError:
        print("Work task cancelled")


async def check_tasks(waiting_task, working_task, waiting_conn_lost_task):
    try:
        await waiting_task
        print("waiting is done")
    except asyncio.CancelledError:
        print("waiting is cancelled")

    try:
        await waiting_conn_lost_task
        print("connection is lost")
    except asyncio.CancelledError:
        print("waiting connection lost is cancelled")

    try:
        await working_task
        print("work is done")
    except asyncio.CancelledError:
        print("work is cancelled")


async def work_done_case():
    working_task = asyncio.create_task(task())
    connection_lost_event = asyncio.Event()
    waiting_conn_lost_task = asyncio.create_task(connection_lost_event.wait())
    waiting_task = asyncio.create_task(wait_any({working_task, waiting_conn_lost_task}))
    await check_tasks(waiting_task, working_task, waiting_conn_lost_task)


async def conn_lost_case():
    working_task = asyncio.create_task(task())
    connection_lost_event = asyncio.Event()
    waiting_conn_lost_task = asyncio.create_task(connection_lost_event.wait())
    waiting_task = asyncio.create_task(wait_any({working_task, waiting_conn_lost_task}))
    await asyncio.sleep(2)
    connection_lost_event.set()  # <---
    await check_tasks(waiting_task, working_task, waiting_conn_lost_task)


async def cancel_waiting_case():
    working_task = asyncio.create_task(task())
    connection_lost_event = asyncio.Event()
    waiting_conn_lost_task = asyncio.create_task(connection_lost_event.wait())
    waiting_task = asyncio.create_task(wait_any({working_task, waiting_conn_lost_task}))
    await asyncio.sleep(2)
    waiting_task.cancel()  # <---
    await check_tasks(waiting_task, working_task, waiting_conn_lost_task)


async def main():
    print("Work done")
    print("-------------------")
    await work_done_case()
    print("\nConnection lost")
    print("-------------------")
    await conn_lost_case()
    print("\nCancel waiting")
    print("-------------------")
    await cancel_waiting_case()


asyncio.run(main())

Output:

work is done

work is cancelled

Cancel waiting
-------------------
waiting is cancelled

It may help if you're less specific. Your expression there is "greedy", which may be interpreted different ways by different programs. Try this in vim:

%s/^<[^>]+>//

suppose below is the html paragraph tag:

<p style="background-color:#ff0000">This is a paragraph.</p>

and we want to change the paragraph color in jquery.

The client side code will be:

<script>
$(document).ready(function(){
    $("p").css("background-color", "yellow");
});
</script> 

Neither. You set the isolation level to READ UNCOMMITTED which is always better than giving individual lock hints. Or, better still, if you care about details like consistency, use snapshot isolation.

The easiest way to find the Lowest Common Ancestor is using the following algorithm:

Examine root node

if value1 and value2 are strictly less that the value at the root node 
    Examine left subtree
else if value1 and value2 are strictly greater that the value at the root node 
    Examine right subtree
else
    return root

public int LCA(TreeNode root, int value 1, int value 2) {
    while (root != null) {
       if (value1 < root.data && value2 < root.data)
           return LCA(root.left, value1, value2);
       else if (value2 > root.data && value2 2 root.data)
           return LCA(root.right, value1, value2);
       else
           return root
    }

    return null;
} 

If you run $ heroku logs you may get a "hint" to what the problem is. For me, Heroku could not detect what type of app I was creating. It required me to set the buildpack. Since I was creating a Node.js app, I just had to run $ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-nodejs. You can read more about it here: https://devcenter.heroku.com/articles/buildpacks. No pushing issues after that.

I know this is an old question, but still posting this here incase someone else gets stuck.

The article "Why is my list black? An Android optimization" in the Android Developers Blog has a thorough explanation of why the list background turns black when scrolling. Simple answer: set cacheColorHint on your list to transparent (#00000000).

Use

for /r path %%var in (*.*) do some_command %%var

with:

• path being the starting path.
• %%var being some identifier.
• *.* being a filemask OR the contents of a variable.
• some_command being the command to execute with the path and var concatenated as parameters.

You can see the source code about this output here:

void InputDispatcher::onDispatchCycleBrokenLocked(
        nsecs_t currentTime, const sp<Connection>& connection) {
    ALOGE("channel '%s' ~ Channel is unrecoverably broken and will be disposed!",
            connection->getInputChannelName());
    CommandEntry* commandEntry = postCommandLocked(
            & InputDispatcher::doNotifyInputChannelBrokenLockedInterruptible);
    commandEntry->connection = connection;
}

It's cause by cycle broken locked...

If you are on php 5.4+, it is cleaner to use session_status():

if (session_status() == PHP_SESSION_ACTIVE) {
  echo 'Session is active';
}

• PHP_SESSION_DISABLED if sessions are disabled.
• PHP_SESSION_NONE if sessions are enabled, but none exists.
• PHP_SESSION_ACTIVE if sessions are enabled, and one exists.

I had to change compileSdkVersion = 26 and buildToolsVersion = '26.0.1' in all my dependencies build.gradle files

This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.

set.py:

import sys
sys.path.append("/tmp/TEST")

loop.py

import sys
import time
while True:
  print sys.path
  time.sleep(1)

run: python loop.py &

This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py. Each has a different set of environment variables. Observe that the output from loop.py does not change because set.py does not change loop.py's environment.

A note on importing

Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append....

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

I have see Eclipse - java.lang.ClassNotFoundException when running junit tests. I had deleted one of the external jar files which was added to the project. After removing the reference of this jar file to the project from Eclipse. i could run the Junit tests .

This calculates square differently and skips even numbers.

const isPrime = (n) => {
  if (n <= 1) return false;
  if (n === 2) return true;
  if (n % 2 === 0) return false;
  //goto square root of number
  for (let i = 3, s = n ** 0.5; i < s; i += 2) {
    if (n % i == 0) return false;
  }
  return true;
};

A while loop can be simulated in cmd.exe with:

:still_more_files
    if %countfiles% leq 21 (
        rem change countfile here
        goto :still_more_files
    )

For example, the following script:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set /a "x = 0"

:more_to_process
    if %x% leq 5 (
        echo %x%
        set /a "x = x + 1"
        goto :more_to_process
    )

    endlocal

outputs:

0
1
2
3
4
5

For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:

    @echo off
    set backupdir=c:\test

:more_files_to_process
    for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
    if %num% gtr 20 (
        cscript /nologo c:\deletefile.vbs %backupdir%
        goto :more_files_to_process
    )

This is an update to this rather old question. I wanted to use the new SF Pro fonts on a website and found no fonts CDN, besides the above noted (applesocial.s3.amazonaws.com).

Clearly, this isn't an official content repository approved by Apple. Actually, I did not find ANY official fonts repository serving Apple fonts, ready to be used by web developers.

And there's a reason - if you read the license agreement that comes with downloading the new SF Pro and other fonts from https://developer.apple.com/fonts/ - it states in the first few paragraphs very clearly:

[...]you may use the Apple Font solely for creating mock-ups of user interfaces to be used in software products running on Apple’s iOS, macOS or tvOS operating systems, as applicable. The foregoing right includes the right to show the Apple Font in screen shots, images, mock-ups or other depictions, digital and/or print, of such software products running solely on iOS, macOS or tvOS.[...]

And:

Except as expressly provided for herein, you may not use the Apple Font to, create, develop, display or otherwise distribute any documentation, artwork, website content or any other work product.

Further:

Except as otherwise expressly permitted [...] (i) only one user may use the Apple Font at a time, and (ii) you may not make the Apple Font available over a network where it could be run or used by multiple computers at the same time.

No more questions for me. Apple clearly does not want their Fonts shared across the web outside their products.

As well as the previous answers are you could always use the Pull attrib as well:

    <ol class="row" id="possibilities">
       <li class="span6">
         <div class="row">
           <div class="span3">
             <p>some text here</p>
             <p>Text Here too</p>
           </div>
         <figure class="span3 pull-right"><img src="img/screenshots/options.png" alt="Some text" /></figure>
        </div>
 </li>
 <li class="span6">
     <div class="row">
         <figure class="span3"><img src="img/qrcode.png" alt="Some text" /></figure>
         <div class="span3">
             <p>Some text</p>
             <p>Some text here too.</p>
         </div>
     </div>
 </li>

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

This has already been answered, but I think the simplest syntax is:

CREATE TABLE History (
    ID int primary key IDENTITY(1,1) NOT NULL,
    . . .

The more complicated constraint index is useful when you actually want to change the options.

By the way, I prefer to name such a column HistoryId, so it matches the names of the columns in foreign key relationships.

The ARM is like an Italian sports car:

• Well balanced, well tuned, engine. Gives good acceleration, and top speed.
• Excellent chases, brakes and suspension. Can stop quickly, can corner without slowing down.

The x86 is like an American muscle car:

• Big engine, big fuel pump. Gives excellent top speed, and acceleration, but uses a lot of fuel.
• Dreadful brakes, you need to put an appointment in your diary, if you want to slowdown.
• Terrible steering, you have to slow down to corner.

In summary: the x86 is based on a design from 1974 and is good in a straight line (but uses a lot of fuel). The arm uses little fuel, does not slowdown for corners (branches).

Metaphor over, here are some real differences.

• Arm has more registers.
• Arm has few special purpose registers, x86 is all special purpose registers (so less moving stuff around).
• Arm has few memory access commands, only load/store register.
• Arm is internally Harvard architecture my design.
• Arm is simple and fast.
• Arm instructions are architecturally single cycle (except load/store multiple).
• Arm instructions often do more than one thing (in a single cycle).
• Where more that one Arm instruction is needed, such as the x86's looping store & auto-increment, the Arm still does it in less clock cycles.
• Arm has more conditional instructions.
• Arm's branch predictor is trivially simple (if unconditional or backwards then assume branch, else assume not-branch), and performs better that the very very very complex one in the x86 (there is not enough space here to explain it, not that I could).
• Arm has a simple consistent instruction set (you could compile by hand, and learn the instruction set quickly).

Another way to fix this would be to go to the properties of the server on eclipse (right click on server -> properties) In general tab you would see location as workspace.metadata. Click on switch location.

None of these worked for me. I am using git-bash on windows. Found out the problem was with my file path formatting.

WRONG:

git clone F:\DEV\MY_REPO\.git

CORRECT:

git clone /F/DEV/MY_REPO/.git

These commands are done from the folder you want the repo folder to appear in.

I agree with @Vishnu's answer. I would like to add that if you want to use the application user in your trigger you can use "context_info" to pass the info to the trigger.

I found following very helpful in doing that: http://jasondentler.com/blog/2010/01/exploiting-context_info-for-fun-and-audit

what about having the image be something selected by the user? Use a input:file tag and then after they select the image, show it on the clientside webpage? That is doable for most things. Right now i am trying to get it working for IE, but as with all microsoft products, it is a cluster fork().

Here are some functions I created for working with fullscreen in the browser.

They provide both enter/exit fullscreen across most major browsers.

function isFullScreen()
{
    return (document.fullScreenElement && document.fullScreenElement !== null)
         || document.mozFullScreen
         || document.webkitIsFullScreen;
}


function requestFullScreen(element)
{
    if (element.requestFullscreen)
        element.requestFullscreen();
    else if (element.msRequestFullscreen)
        element.msRequestFullscreen();
    else if (element.mozRequestFullScreen)
        element.mozRequestFullScreen();
    else if (element.webkitRequestFullscreen)
        element.webkitRequestFullscreen();
}

function exitFullScreen()
{
    if (document.exitFullscreen)
        document.exitFullscreen();
    else if (document.msExitFullscreen)
        document.msExitFullscreen();
    else if (document.mozCancelFullScreen)
        document.mozCancelFullScreen();
    else if (document.webkitExitFullscreen)
        document.webkitExitFullscreen();
}

function toggleFullScreen(element)
{
    if (isFullScreen())
        exitFullScreen();
    else
        requestFullScreen(element || document.documentElement);
}

Just had this problem, what worked for me was to use localhost.fiddler:

 <endpoint address="http://localhost.fiddler/test/test.svc"
            binding="basicHttpBinding" 
            bindingConfiguration="customBinding" 
            contract="test" 
            name="customBinding"/>

You should be able to continue the sequences directly in your existing -f specification.

To skip both 5 and 7, try:

cut -d, -f-4,6-6,8-

As you're skipping a single sequential column, this can also be written as:

cut -d, -f-4,6,8-

To keep it going, if you wanted to skip 5, 7, and 11, you would use:

cut -d, -f-4,6-6,8-10,12-

To put it into a more-clear perspective, it is easier to visualize when you use starting/ending columns which go on the beginning/end of the sequence list, respectively. For instance, the following will print columns 2 through 20, skipping columns 5 and 11:

cut -d, -f2-4,6-10,12-20

So, this will print "2 through 4", skip 5, "6 through 10", skip 11, and then "12 through 20".

Html:

<div class="outerDiv">
    <div class="innerDiv">Content</div>
</div>

CSS:

.outerDiv{
    background: #000;
    padding: 10px;
 }

 .innerDiv{
     border: 2px dashed #fff;
     min-height: 200px; //adding min-height as there is no content inside

 }

Since Bootstrap 3 you have to use checkbox-inline and radio-inline classes on the label.

This takes care of vertical alignment.

<label class="checkbox-inline">
    <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="radio-inline">
    <input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>

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

document.addEventListener('DOMContentLoaded',fnName);

Hope this helps some one.

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

If you should loose your entry point in your Storyboard or simply wish to change the entry point you can specify this in Interface Builder. To set a new entry point you must first decide which ViewController will act as the new entry point and in the Attribute Inspector select the Initial Scene checkbox.

You can try: http://www.scott-sherwood.com/ios-5-specifying-the-entry-point-of-your-storyboard/

Looking at the NSPredicate reference, it looks like you need to surround your substitution character with quotes. For example, your current predicate reads: (SPORT == Football) You want it to read (SPORT == 'Football'), so your format string needs to be @"(SPORT == '%@')".

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

<style>
a{
cursor: default;
}
</style>

In the above code [cursor:default] is used. Default is the usual arrow cursor that appears.

And if you use [cursor: pointer] then you can access to the hand like cursor that appears when you hover over a link.

To know more about cursors and their appearance click the below link: https://www.w3schools.com/cssref/pr_class_cursor.asp

There are multiple schemas for "JUnit" and "xUnit" results.

• XSD for Apache Ant's JUnit output can be found at : https://github.com/windyroad/JUnit-Schema (credit goes to this answer: https://stackoverflow.com/a/4926073/1733117)
• XSD from Jenkins xunit-plugin can be found at : https://github.com/jenkinsci/xunit-plugin/tree/master/src/main/resources/org/jenkinsci/plugins/xunit/types (under model/xsd)

Please note that there are several versions of the schema in use by the Jenkins xunit-plugin (the current latest version is junit-10.xsd which adds support for Erlang/OTP Junit format).

Some testing frameworks as well as "xUnit"-style reporting plugins also use their own secret sauce to generate "xUnit"-style reports, those may not use a particular schema (please read: they try to but the tools may not validate against any one schema). Python unittests in Jenkins? gives a quick comparison of several of these libraries and slight differences between the xml reports generated.

Try to use this , it works perfectly for me

  // 

   varb = new List<object>();

 // Example 

   varb.Add(new[] { float.Parse(GridView1.Rows[1].Cells[2].Text )});

 // JSON  + Serializ

public string Json()
        {  
            return (new JavaScriptSerializer()).Serialize(varb);
        }


//  Jquery SIDE 

  var datasets = {
            "Products": {
                label: "Products",
                data: <%= getJson() %> 
            }

         //Store the number of days after which you want to delete the logs.
         int Days = 30;

          // Storing the path of the directory where the logs are stored.
           String DirPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6) + "\\Log(s)\\";

          //Fetching all the folders.
            String[] objSubDirectory = Directory.GetDirectories(DirPath);

            //For each folder fetching all the files and matching with date given 
            foreach (String subdir in objSubDirectory)     
            {
                //Getting the path of the folder                 
                String strpath = Path.GetFullPath(subdir);
                //Fetching all the files from the folder.
                String[] strFiles = Directory.GetFiles(strpath);
                foreach (string files in strFiles)
                {
                    //For each file checking the creation date with the current date.
                    FileInfo objFile = new FileInfo(files);
                    if (objFile.CreationTime <= DateTime.Now.AddDays(-Days))
                    {
                        //Delete the file.
                        objFile.Delete();
                    }
                }

                //If folder contains no file then delete the folder also.
                if (Directory.GetFiles(strpath).Length == 0)
                {
                    DirectoryInfo objSubDir = new DirectoryInfo(subdir);
                    //Delete the folder.
                    objSubDir.Delete();
                }

            }

I had this problem but didn't have a version conflict in my package.json.

My package-lock.json was somehow out of sync with package json though. Deleting and regenerating it worked for me.

The following can be used in the eBook space:

application/vnd.ms-opentype

I would imagine that it is the same for the web.

Changing the NPM repo URL to HTTP works as a quick-fix, but I wanted to use HTTPS.

In my case, the proxy at my employer (ZScaler) was causing issues (as it acts as a MITM, causing certification verification issues)

I forgot I found a script that helps with this and Git (for cloning GitHub repos via HTTPS had the same issue) and forked it for my use

Basically, it does the following for git:

git config --global http.proxy http://gateway.zscaler.net:80/
git config --system http.proxy http://gateway.zscaler.net:80/

and for Node, it adds proxy=http://gateway.zscaler.net:80/ to the end of c:\Users\$USERNAME\npm\.npmrc

That solved the issue for me.

How about reinstalling the node module? Go to the root directory of the project and remove the current node modules and install again.

These are the commands : rm -rf node_modules npm install

OR

npm uninstall -g react-native-cli and

npm install -g react-native-cli

Similar to getting the length of a dataframe, len(df), the following worked for pandas and blaze:

Total = sum(df['MyColumn'])

or alternatively

Total = sum(df.MyColumn)
print Total

If you are familiar with gcc, as you indicated in the question, you can install MinGW, which will set a linux-like compile environment in Win7. Otherwise, Visual Studio 2010 Express is the best choice.

As you said, you want hash to contain only numbers.

var reg = new RegExp('^[0-9]+$');

or

var reg = new RegExp('^\\d+$');

\d and [0-9] both mean the same thing. The + used means that search for one or more occurring of [0-9].

Here is a example using iTextSharp

public static void MergePdf(Stream outputPdfStream, IEnumerable<string> pdfFilePaths)
{
    using (var document = new Document())
    using (var pdfCopy = new PdfCopy(document, outputPdfStream))
    {
        pdfCopy.CloseStream = false;
        try
        {
            document.Open();
            foreach (var pdfFilePath in pdfFilePaths)
            {
                using (var pdfReader = new PdfReader(pdfFilePath))
                {
                    pdfCopy.AddDocument(pdfReader);
                    pdfReader.Close();
                }
            }
        }
        finally
        {
            document?.Close();
        }
    }
}

The PdfReader constructor has many overloads. It's possible to replace the parameter type IEnumerable<string> with IEnumerable<Stream> and it should work as well. Please notice that the method does not close the OutputStream, it delegates that task to the Stream creator.

If you're only running the commands in one shot then you can just use subprocess.check_output convenience function:

def subprocess_cmd(command):
    output = subprocess.check_output(command, shell=True)
    print output

As far as aspect oriented logging is concerned I was recommended PostSharp on another SO question -

Aspect Oriented Logging with Unity\T4\anything else

The link provided in the answer is worth visiting if you are evaluating logging frameworks.

you can also use for loop to append or write data to a file. example:

for i in {1..10}; do echo "Hello Linux Terminal"; >> file.txt done

">>" is used to append.

">" is used to write.

Update for PHP 7 (thanks shock_gone_wild)

PHP 7 introduces the so called null coalescing operator which simplifies the below statements to:

$var = $var ?? "default";

Before PHP 7

No, there is no special operator or special syntax for this. However, you could use the ternary operator:

$var = isset($var) ? $var : "default";

Or like this:

isset($var) ?: $var = 'default';

The featured (but small and simple) library you can use is JSDialog: js.plus/products/jsdialog

Here is a sample for creating a dialog with Yes and No buttons:

JSDialog.showConfirmDialog(
    "Save document before it will be closed?\nIf you press `No` all unsaved changes will be lost.",
    function(result) {
        // check result here
    },
    "warning",
    "yes|no|cancel"
);

I think that using colnames and rownames makes the most sense; here's why.

Using names has several disadvantages. You have to remember that it means "column names", and it only works with data frame, so you'll need to call colnames whenever you use matrices. By calling colnames, you only have to remember one function. Finally, if you look at the code for colnames, you will see that it calls names in the case of a data frame anyway, so the output is identical.

rownames and row.names return the same values for data frame and matrices; the only difference that I have spotted is that where there aren't any names, rownames will print "NULL" (as does colnames), but row.names returns it invisibly. Since there isn't much to choose between the two functions, rownames wins on the grounds of aesthetics, since it pairs more prettily withcolnames. (Also, for the lazy programmer, you save a character of typing.)

It's simple, whenever Docker build is run, docker wants to know, what's the image name, so we need to pass -t : . Now make sure you are in the same directory where you have your Dockerfile and run

docker build -t <image_name>:<version> . Example docker build -t my_apache:latest . assuming you are in the same directory as your Dockerfile otherwise pass -f flag and the Dockerfile.

docker build -t my_apache:latest -f ~/Users/documents/myapache/Dockerfile

$.post('someUri', { }, 
  function(data){ doSomeStuff })
 .fail(function(error) { alert(error.responseJSON) });

.scroll {
   width: 200px; height: 400px;
   overflow: auto;
}

Please use the following expression to get the length of the number.

length = variableName.toString().length

If you want to retrieve the key's value if it exists, you can also use

try:
    value = a[key]
except KeyError:
    # Key is not present
    pass

If you want to retrieve a default value when the key does not exist, use value = a.get(key, default_value). If you want to set the default value at the same time in case the key does not exist, use value = a.setdefault(key, default_value).

Installation

OpCache is compiled by default on PHP5.5+. However it is disabled by default. In order to start using OpCache in PHP5.5+ you will first have to enable it. To do this you would have to do the following.

Add the following line to your php.ini:

zend_extension=/full/path/to/opcache.so (nix)
zend_extension=C:\path\to\php_opcache.dll (win)

Note that when the path contains spaces you should wrap it in quotes:

zend_extension="C:\Program Files\PHP5.5\ext\php_opcache.dll"

Also note that you will have to use the zend_extension directive instead of the "normal" extension directive because it affects the actual Zend engine (i.e. the thing that runs PHP).

Usage

Currently there are four functions which you can use:

opcache_get_configuration():

Returns an array containing the currently used configuration OpCache uses. This includes all ini settings as well as version information and blacklisted files.

var_dump(opcache_get_configuration());

opcache_get_status():

This will return an array with information about the current status of the cache. This information will include things like: the state the cache is in (enabled, restarting, full etc), the memory usage, hits, misses and some more useful information. It will also contain the cached scripts.

var_dump(opcache_get_status());

opcache_reset():

Resets the entire cache. Meaning all possible cached scripts will be parsed again on the next visit.

opcache_reset();

opcache_invalidate():

Invalidates a specific cached script. Meaning the script will be parsed again on the next visit.

opcache_invalidate('/path/to/script/to/invalidate.php', true);

Maintenance and reports

There are some GUI's created to help maintain OpCache and generate useful reports. These tools leverage the above functions.

One more thing - if You edited the shell script in some Windows text editor, which produces the \r\n line-endings, cygwin's bash wouldn't accept those \r. Just run dos2unix testit.sh before executing the script:

C:\cygwin\bin\dos2unix testit.sh
C:\cygwin\bin\bash testit.sh

attr_accessor is a Ruby method that makes a getter and a setter. attr_accessible is a Rails method that allows you to pass in values to a mass assignment: new(attrs) or update_attributes(attrs).

Here's a mass assignment:

Order.new({ :type => 'Corn', :quantity => 6 })

You can imagine that the order might also have a discount code, say :price_off. If you don't tag :price_off as attr_accessible you stop malicious code from being able to do like so:

Order.new({ :type => 'Corn', :quantity => 6, :price_off => 30 })

Even if your form doesn't have a field for :price_off, if it's in your model it's available by default. This means a crafted POST could still set it. Using attr_accessible white lists those things that can be mass assigned.

Use Reader.read(). A return value of -1 means end of stream; else, cast to char.

This code reads character data from a list of file arguments:

public class CharacterHandler {
    //Java 7 source level
    public static void main(String[] args) throws IOException {
        // replace this with a known encoding if possible
        Charset encoding = Charset.defaultCharset();
        for (String filename : args) {
            File file = new File(filename);
            handleFile(file, encoding);
        }
    }

    private static void handleFile(File file, Charset encoding)
            throws IOException {
        try (InputStream in = new FileInputStream(file);
             Reader reader = new InputStreamReader(in, encoding);
             // buffer for efficiency
             Reader buffer = new BufferedReader(reader)) {
            handleCharacters(buffer);
        }
    }

    private static void handleCharacters(Reader reader)
            throws IOException {
        int r;
        while ((r = reader.read()) != -1) {
            char ch = (char) r;
            System.out.println("Do something with " + ch);
        }
    }
}

The bad thing about the above code is that it uses the system's default character set. Wherever possible, prefer a known encoding (ideally, a Unicode encoding if you have a choice). See the Charset class for more. (If you feel masochistic, you can read this guide to character encoding.)

(One thing you might want to look out for are supplementary Unicode characters - those that require two char values to store. See the Character class for more details; this is an edge case that probably won't apply to homework.)

Option 1

Use float:left on both div elements and set a % width for both div elements with a combined total width of 100%.

Use box-sizing: border-box; on the floating div elements. The value border-box forces the padding and borders into the width and height instead of expanding it.

Use clearfix on the <div id="wrapper"> to clear the floating child elements which will make the wrapper div scale to the correct height.

.clearfix:after {
   content: " "; 
   visibility: hidden;
   display: block;
   height: 0;
   clear: both;
}

#first, #second{
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
}

#wrapper {
    width: 500px;
    border: 1px solid black;
}
#first {
    border: 1px solid red;
    float:left;
    width:50%;
}
#second {
    border: 1px solid green;
    float:left;
    width:50%;
}

http://jsfiddle.net/dqC8t/3381/

Option 2

Use position:absolute on one element and a fixed width on the other element.

Add position:relative to <div id="wrapper"> element to make child elements absolutely position to the <div id="wrapper"> element.

#wrapper {
    width: 500px;
    border: 1px solid black;
    position:relative;
}
#first {
    border: 1px solid red;
    width:100px;
}
#second {
    border: 1px solid green;
    position:absolute;
    top:0;
    left:100px;
    right:0;
}

http://jsfiddle.net/dqC8t/3382/

Option 3

Use display:inline-block on both div elements and set a % width for both div elements with a combined total width of 100%.

And again (same as float:left example) use box-sizing: border-box; on the div elements. The value border-box forces the padding and borders into the width and height instead of expanding it.

NOTE: inline-block elements can have spacing issues as it is affected by spaces in HTML markup. More information here: https://css-tricks.com/fighting-the-space-between-inline-block-elements/

#first, #second{
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
}

#wrapper {
    width: 500px;
    border: 1px solid black;
    position:relative;
}

#first {
    width:50%;
    border: 1px solid red;
    display:inline-block;
}

#second {
    width:50%;
    border: 1px solid green;
    display:inline-block;
}

A final option would be to use the new display option named flex, but note that browser compatibility might come in to play:

I tried the previous answer about pinch-to-zoom

document.documentElement.addEventListener('touchstart', function (event) {
    if (event.touches.length > 1) {
        event.preventDefault();
    }
}, false);

however sometime the screen still zoom when the event.touches.length > 1 I found out the best way is using touchmove event, to avoid any finger moving on the screen. The code will be something like this:

document.documentElement.addEventListener('touchmove', function (event) {
    event.preventDefault();      
}, false);

Hope it will help.

Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices.

You haven't shown us the most important part : the mapping and initialization of the relationships between your entities (i.e. the part you have problems with). So I'll show you how it should look like.

If you make the relationships bidirectional, you should thus have

class User {
    @OneToMany(mappedBy = "user")
    private Set<UserService> userServices = new HashSet<UserService>();
}

class UserService {
    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "service_code")
    private Service service;

    @Column(name = "blocked")
    private boolean blocked;
}

class Service {
    @OneToMany(mappedBy = "service")
    private Set<UserService> userServices = new HashSet<UserService>();
}

If you don't put any cascade on your relationships, then you must persist/save all the entities. Although only the owning side of the relationship (here, the UserService side) must be initialized, it's also a good practice to make sure both sides are in coherence.

User user = new User();
Service service = new Service();
UserService userService = new UserService();

user.addUserService(userService);
userService.setUser(user);

service.addUserService(userService);
userService.setService(service);

session.save(user);
session.save(service);
session.save(userService);

**403 Forbidden **

You don't have permission to access /Folder-Name/ on this server**

The solution for this problem is:

1.go to etc/apache2/apache2.conf

2.find the below code and change AllowOverride all to AllowOverride none

 <Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride all      Change this to--->  AllowOverride none
    Require all granted
 </Directory>

It will work fine on your Ubuntu server

Another solution if you don't want to modify your settings:

Download jms-1.1.jar from JBoss repository then:

mvn install:install-file -DgroupId=javax.jms -DartifactId=jms -Dversion=1.1 -Dpackaging=jar -Dfile=jms-1.1.jar

Fancy indexing requires you to provide all indices for each dimension. You are providing 3 indices for the first one, and only 2 for the second one, hence the error. You want to do something like this:

>>> a[[[0, 0], [1, 1], [3, 3]], [[0,2], [0,2], [0, 2]]]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

That is of course a pain to write, so you can let broadcasting help you:

>>> a[[[0], [1], [3]], [0, 2]]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

This is much simpler to do if you index with arrays, not lists:

>>> row_idx = np.array([0, 1, 3])
>>> col_idx = np.array([0, 2])
>>> a[row_idx[:, None], col_idx]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

For Jackson versions < 2.0 use this annotation on the class being serialized:

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

Put the line in a stringstream and extract word by word back:

#include <iostream>
#include <sstream>
using namespace std;

int main()
{
    string t;
    getline(cin,t);

    istringstream iss(t);
    string word;
    while(iss >> word) {
        /* do stuff with word */
    }
}

Of course, you can just skip the getline part and read word by word from cin directly.

And here you can read why is using namespace std considered bad practice.

You can use the -S flag to read from std input. Find below an example:

function shutd()
{
  echo "mySuperSecurePassword" | sudo -S shutdown -h now
}

As Maciej Jonczyk mentioned, you may also need to increase margins

par(mar=c(8,8,1,1)) # adjust as needed
plot(...)

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

Then add a if condition as follows:-

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")) {
   //Your code
}       

There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/

if using /bin/sh you can use:

if [ <condition> ] && [ <condition> ]; then
    ...
fi

if using /bin/bash you can use:

if [[ <condition> && <condition> ]]; then
    ...

Edit: I just noted that you are trying to use a gmail address as the from value. This is not going to work, and the ISP is right in overwriting it. If you want to redirect the replies to your outgoing messages, use reply-to.

A workaround for valid addresses that works with many ISPs:

try adding a fifth parameter to your mail() command:

I am new to app programming and this was the first problem I ran into when I tried to get a sample program debug using my LG G3 device. The post above with detailed instructions should work for all. I am adding my experience in case it helps other:

I had followed instructions step by step but one. That is, installing the USB driver from my OEM. My phone kept notifying that the debugging is on (in the notification area) and I could transfer data as well as charge. That made me think that appropriate USB drivers are installed. But it wasn't. Finally I went to LG site and downloaded the USB driver for my LG G3. Right after I installed the driver and reconnected the phone to the computer via the cable, I got the RSA key prompt. My Chrome now detects it and I was able to get my app run on my phone via Android studio as well.

First run:

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force

Then run the command

npm install cross-env

npm install 

and then you can also run

npm run dev

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

The entity type 'DisplayFormatAttribute' requires a primary key to be defined.

In my case I figured out the problem was that I used properties like this:

public string LastName { get; set; }  //OK
public string Address { get; set; }   //OK 
public string State { get; set; }     //OK
public int? Zip { get; set; }         //OK
public EmailAddressAttribute Email { get; set; } // NOT OK
public PhoneAttribute PhoneNumber { get; set; }  // NOT OK

Not sure if there is a better way to solve it but I changed the Email and PhoneNumber attribute to a string. Problem solved.

In case of windows: use curl --proxy "" ...

In your Lad model class, add an override to the ToString() method that returns a JSON string version of your Lad object.
Note: you will need to import System.Text.Json;

using System.Text.Json;

class MyDate
{
    int year, month, day;
}

class Lad
{
    public string firstName { get; set; };
    public string lastName { get; set; };
    public MyDate dateOfBirth { get; set; };
    public override string ToString() => JsonSerializer.Serialize<Lad>(this);
}

With WinForms you can use the ErrorProvider in conjunction with the Validating event to handle the validation of user input. The Validating event provides the hook to perform the validation and ErrorProvider gives a nice consistent approach to providing the user with feedback on any error conditions.

Merge conflicts happens when changes are made to a file at the same time. Here is how to solve it.

git CLI

Here are simple steps what to do when you get into conflicted state:

1. Note the list of conflicted files with: git status (under Unmerged paths section).

2. Solve the conflicts separately for each file by one of the following approaches:

   • Use GUI to solve the conflicts: git mergetool (the easiest way).

   • To accept remote/other version, use: git checkout --theirs path/file. This will reject any local changes you did for that file.

   • To accept local/our version, use: git checkout --ours path/file

     ^{However you've to be careful, as remote changes that conflicts were done for some reason.}

     Related: What is the precise meaning of "ours" and "theirs" in git?

   • Edit the conflicted files manually and look for the code block between <<<<</>>>>> then choose the version either from above or below =====. See: How conflicts are presented.

   • Path and filename conflicts can be solved by git add/git rm.

3. Finally, review the files ready for commit using: git status.

   If you still have any files under Unmerged paths, and you did solve the conflict manually, then let Git know that you solved it by: git add path/file.

4. If all conflicts were solved successfully, commit the changes by: git commit -a and push to remote as usual.

DiffMerge

I've successfully used DiffMerge which can visually compare and merge files on Windows, macOS and Linux/Unix.

It graphically can show the changes between 3 files and it allows automatic merging (when safe to do so) and full control over editing the resulting file.

^{Image source: DiffMerge (Linux screenshot)}

Simply download it and run in repo as:

git mergetool -t diffmerge .

macOS

On macOS you can install via:

brew install caskroom/cask/brew-cask
brew cask install diffmerge

And probably (if not provided) you need the following extra simple wrapper placed in your PATH (e.g. /usr/bin):

#!/bin/sh
DIFFMERGE_PATH=/Applications/DiffMerge.app
DIFFMERGE_EXE=${DIFFMERGE_PATH}/Contents/MacOS/DiffMerge
exec ${DIFFMERGE_EXE} --nosplash "$@"

Then you can use the following keyboard shortcuts:

• ?-Alt-Up/Down to jump to previous/next changes.
• ?-Alt-Left/Right to accept change from left or right

Alternatively you can use opendiff (part of Xcode Tools) which lets you merge two files or directories together to create a third file or directory.

As stated in this answer:

Application.Wait (Now + TimeValue("0:00:01"))

will wait for 1 second

For database : USE db_name; SELECT @@character_set_database;

ActionListener gets fired first, with an option to modify the response, before Action gets called and determines the location of the next page.

If you have multiple buttons on the same page which should go to the same place but do slightly different things, you can use the same Action for each button, but use a different ActionListener to handle slightly different functionality.

Other posters have addressed the question about how contains() works.

An equally important aspect of your question is how to properly implement equals(). And the answer to this is really dependent on what constitutes object equality for this particular class. In the example you provided, if you have two different objects that both have x=5, are they equal? It really depends on what you are trying to do.

If you are only interested in object equality, then the default implementation of .equals() (the one provided by Object) uses identity only (i.e. this == other). If that's what you want, then just don't implement equals() on your class (let it inherit from Object). The code you wrote, while kind of correct if you are going for identity, would never appear in a real class b/c it provides no benefit over using the default Object.equals() implementation.

If you are just getting started with this stuff, I strongly recommend the Effective Java book by Joshua Bloch. It's a great read, and covers this sort of thing (plus how to correctly implement equals() when you are trying to do more than identity based comparisons)

None of the answers satisfied my needs fully, so here we go:

git branch --merged | grep -E "(feature|bugfix|hotfix)/" | xargs git branch -D && git remote prune origin

This will delete all local branches which are merged and starting with feature/, bugfix/ or hotfix/. Afterwards the upstream remote origin is pruned (you may have to enter a password).

Works on Git 1.9.5.

I was able to solve this using this alter statement on my table that had two datetime fields.

ALTER TABLE `test_table`
  CHANGE COLUMN `created_dt` `created_dt` TIMESTAMP NOT NULL DEFAULT '0000-00-00 00:00:00',
  CHANGE COLUMN `updated_dt` `updated_dt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP;

This works as you would expect the now() function to work. Inserting nulls or ignoring the created_dt and updated_dt fields results in a perfect timestamp value in both fields. Any update to the row changes the updated_dt. If you insert records via the MySQL query browser you needed one more step, a trigger to handle the created_dt with a new timestamp.

CREATE TRIGGER trig_test_table_insert BEFORE INSERT ON `test_table`
    FOR EACH ROW SET NEW.created_dt = NOW();

The trigger can be whatever you want I just like the naming convention [trig]_[my_table_name]_[insert]

wrap all the script between this...

<script>
    $.noConflict();
    jQuery( document ).ready(function( $ ) {
      // Code that uses jQuery's $ can follow here.
    });
</script>

Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If you need to use another JavaScript library alongside jQuery, return control of $ back to the other library with a call to $.noConflict(). Old references of $ are saved during jQuery initialization; noConflict() simply restores them.

Just follow the official instructions from ShellEd's InstallGuide

mysql_* functions have been removed in PHP 7.

You probably have PHP 7 in XAMPP. You now have two alternatives: MySQLi and PDO.

Additionally, here is a nice wiki page about PDO.

this error happen with me because I did the following

1. I changed Column name of table in database
2. (I did not used Update Model from database in Edmx) I Renamed manually Property name to match the change in database schema
3. I did some refactoring to change name of the property in the class to be the same as database schema and models in Edmx

Although all of this, I got this error

so what to do

1. I Deleted the model from Edmx
2. Right Click and Update Model from database

this will regenerate the model, and entity framework will not give you this error

hope this help you

I used read_csv from the readr package

In my experience, the parameter row.names=NULL in the read.csv function will lead to a wrong reading of the file if a column name is missing, i.e. every column will be shifted.

read_csv solves this.

In the hypothetical situation where you could perform a potentially expensive non-const operation on an object, returning by const-value prevents you from accidentally calling this operation on a temporary. Imagine that + returned a non-const value, and you could write:

(a + b).expensive();

In the age of C++11, however, it is strongly advised to return values as non-const so that you can take full advantage of rvalue references, which only make sense on non-constant rvalues.

In summary, there is a rationale for this practice, but it is essentially obsolete.

Giving below another option. This will zip up a full folder and will write the archive to a given path with the given name.

Requires .NET 3 or above

Add-Type -assembly "system.io.compression.filesystem"

$source = 'Source path here'    
$destination = "c:\output\dummy.zip"

If(Test-path $destination) {Remove-item $destination}

[io.compression.zipfile]::CreateFromDirectory($Source, $destination)

Answering the additional question:

my following test code for typeid does not output the correct type name. what's wrong?

There isn't anything wrong. What you see is the string representation of the type name. The standard C++ doesn't force compilers to emit the exact name of the class, it is just up to the implementer(compiler vendor) to decide what is suitable. In short, the names are up to the compiler.

These are two different tools. typeof returns the type of an expression, but it is not standard. In C++0x there is something called decltype which does the same job AFAIK.

decltype(0xdeedbeef) number = 0; // number is of type int!
decltype(someArray[0]) element = someArray[0];

Whereas typeid is used with polymorphic types. For example, lets say that cat derives animal:

animal* a = new cat; // animal has to have at least one virtual function
...
if( typeid(*a) == typeid(cat) )
{
    // the object is of type cat! but the pointer is base pointer.
}

I hope this helps you

Use sp_rename

EXEC sp_RENAME 'TableName.OldColumnName' , 'NewColumnName', 'COLUMN'

See: SQL SERVER – How to Rename a Column Name or Table Name

Documentation: sp_rename (Transact-SQL)

For your case it would be:

EXEC sp_RENAME 'table_name.old_name', 'new_name', 'COLUMN'

Remember to use single quotes to enclose your values.

So the most up-voted "Better Way" is a little deprecated so here is my edit and other solutions:

Javascript + jQuery

$.ajax({
    type: 'GET',
    url: 'http://api.instagram.com/oembed?callback=&url='+Url, //You must define 'Url' for yourself
    cache: false,
    dataType: 'json',
    jsonp: false,
    success: function (data) {
       var MediaID = data.media_id;
   }
});

PHP

$your_url = "" //Input your url
$api = file_get_contents("http://api.instagram.com/oembed?callback=&url=" . your_url);      
$media_id = json_decode($api,true)['media_id'];

So, this is just an updated version of @George's code and is currently working. However, I made other solutions, and some even avoid an ajax request:

Shortcode Ajax Solution

Certain Instagram urls use a shortened url syntax. This allows the client to just use the shortcode in place of the media id if requested properly.

An example shortcode url looks like this: https://www.instagram.com/p/Y7GF-5vftL/

The Y7GF-5vftL is your shortcode for the picture.

Using Regexp:

var url = "https://www.instagram.com/p/Y7GF-5vftL/"; //Define this yourself
var Key = /p\/(.*?)\/$/.exec(url)[1];

In the same scope, Key will contain your shortcode. Now to request, let's say, a low res picture using this shortcode, you would do something like the following:

    $.ajax({
        type: "GET",
        dataType: "json",
        url: "https://api.instagram.com/v1/media/shortcode/" + Key + "?access_token=" + access_token, //Define your 'access_token'
        success: function (RawData) {
            var LowResURL = RawData.data.images.low_resolution.url;
        }
    });

There is lots of other useful information, including the media id, in the returned RawData structure. Log it or look up the api documentation to see.

Shortcode Conversion Solution

You can actually convert your shortcode to the id fairly easily! Here's a simple way to do it in javascript:

function shortcodeToInstaID(Shortcode) {
      var char;
      var id = 0;
      var alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';
      for (var i = 0; i < Shortcode.length; i++) {
          char = Shortcode[i];
          id = (id * 64) + alphabet.indexOf(char);
      }
      return id;
  }

Note: If you want a more robust node.js solution, or want to see how you would convert it back, check out @Slang's module on npm.

Full Page Solution

So what if you have the URL to a full Instagram page like: https://www.instagram.com/p/BAYYJBwi0Tssh605CJP2bmSuRpm_Jt7V_S8q9A0/

Well, you can actually read the HTML to find a meta property that contains the Media ID. There are also a couple other algorithms you can perform on the URL itself to get it, but I believe that requires too much effort so we will keep it simple. Either query the meta tag al:ios:url or iterate through the html. Since reading metatags is posted all over, I'll show you how to iterate.

NOTE: This is a little unstable and is vulnerable to being patched. This method does NOT work on a page that uses a preview box. So if you give it the current HTML when you click on a picture in someone's profile, this WILL break and return a bad Media ID.

function getMediaId(HTML_String) {
  var MediaID = "";
  var e = HTML_String.indexOf("al:ios:url") + 42; //HTML_String is a variable that contains all of the HTML text as a string for the current document. There are many different ways to retrieve this so look one up. 
  for (var i = e; i <= e + 100; i++) { //100 should never come close to being reached
      if (request.source.charAt(i) == "\"")
         break;
      MediaID += request.source.charAt(i);
  }
  return MediaID;
}

And there you go, a bunch of different ways to use Instagram's api to get a Media ID. Hope one fixes your struggles.

I'm a little surprised nobody has suggested the most obvious solution:

grep -v '^#' filename

This solves the problem as stated.

But note that a common convention is for everything from a # to the end of a line to be treated as a comment:

sed 's/#.*$//' filename

though that treats, for example, a # character within a string literal as the beginning of a comment (which may or may not be relevant for your case) (and it leaves empty lines).

A line starting with arbitrary whitespace followed by # might also be treated as a comment:

grep -v '^ *#' filename

if whitespace is only spaces, or

grep -v '^[  ]#' filename

where the two spaces are actually a space followed by a literal tab character (type "control-v tab").

For all these commands, omit the filename argument to read from standard input (e.g., as part of a pipe).

Although this is an old post, I thought that a simple function can make the code more readable and keeps with jQuery chaining code-style:

String.prototype.toNum = function(){
    return parseInt(this, 10);
}

can be used with jQuery:

var padding_top = $('#some_div').css('padding-top'); //string: "10px"
var padding_top = $('#some_div').css('padding-top').toNum(); //number: 10`

or with any String object:

"123".toNum(); //123 (number)`

Using JQuery would take care of that browser inconsistency. With the jquery library included in your project simply write:

$('#yourDivName').html('yourtHTML');

You may also consider using:

$('#yourDivName').append('yourtHTML');

This will add your gallery as the last item in the selected div. Or:

$('#yourDivName').prepend('yourtHTML');

This will add it as the first item in the selected div.

See the JQuery docs for these functions:

• http://api.jquery.com/append/
• http://api.jquery.com/prepend/

Using TimeZones class makes it easy to create timezone specific date.

TimeZoneInfo.ConvertTime(DateTime.Now, TimeZoneInfo.FindSystemTimeZoneById(TimeZones.Paris.Id));

If you are using LESS or Sass, You can try this:

.btn {
  &[disabled] {
    opacity: 0.6;
  }
  &:hover, &:active {
    &:not([disabled]) {
      background-color: darken($orange, 15);
    }
  }
}

Try pfiles PID to show all open files for a process.

I am a happy boost user and would certainly use Andreas' solution. But if you didn't have access to the boost libs you can use the stream library:

ifstream file(argv[1]);
if (!file)
{
    // Can't open file
}

It's not quite as nice as boost::filesystem::exists since the file will actually be opened...but then that's usually the next thing you want to do anyway.

I faced with the same error, when i downloaded the Jmeter Source, and it got fixed once i downloaded Jmeter Binary. Please watch this video.

Another neat option is to use the Directive as an element and not as an attribute.

@Directive({
   selector: 'app-directive'
})
export class InformativeDirective implements AfterViewInit {

    @Input()
    public first: string;

    @Input()
    public second: string;

    ngAfterViewInit(): void {
       console.log(`Values: ${this.first}, ${this.second}`);
    }
}

And this directive can be used like that:

<app-someKindOfComponent>
    <app-directive [first]="'first 1'" [second]="'second 1'">A</app-directive>
    <app-directive [first]="'First 2'" [second]="'second 2'">B</app-directive>
    <app-directive [first]="'First 3'" [second]="'second 3'">C</app-directive>
</app-someKindOfComponent>`

Simple, neat and powerful.

I think it's worth answering the generic question "R - test if string contains string" here.

For that, use the grep function.

# example:
> if(length(grep("ab","aacd"))>0) print("found") else print("Not found")
[1] "Not found"
> if(length(grep("ab","abcd"))>0) print("found") else print("Not found")
[1] "found"

You can use XmlDocument. Also some XPath can be useful.

Just a simple example

XmlDocument doc = new XmlDocument();
doc.Load("sample.xml");
XmlElement root = doc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("some_node"); // You can also use XPath here
foreach (XmlNode node in nodes)
{
   // use node variable here for your beeds
}

Importing a whole library seems inefficient when all you need is essentially two lines of code...

$ldap = ldap_connect("ldap.example.com");
if ($bind = ldap_bind($ldap, $_POST['username'], $_POST['password'])) {
  // log them in!
} else {
  // error message
}

Here's some code with a dummy geom_blank layer,

range_act <- range(range(results$act), range(results$pred))

d <- reshape2::melt(results, id.vars = "pred")

dummy <- data.frame(pred = range_act, value = range_act,
                    variable = "act", stringsAsFactors=FALSE)

ggplot(d, aes(x = pred, y = value)) +
  facet_wrap(~variable, scales = "free") +
  geom_point(size = 2.5) + 
  geom_blank(data=dummy) + 
  theme_bw()

You can just type these 3 commands from command prompt:

1. start

2. start cmd

3. start cmd.exe

You need make sure to start the session at the top of every PHP file where you want to use the $_SESSION superglobal. Like this:

<?php
  session_start();
  echo $_SESSION['youritem'];
?>

You forgot the Session HELPER.

Check this link : book.cakephp.org/2.0/en/core-libraries/helpers/session.html

http://cr.yp.to/qhasm.html has many examples.

No, the way that you're doing it is just fine. implode() only takes 1-2 parameters (if you just supply an array, it joins the pieces by an empty string).

Use shared variable to communicate. For example like this:

import multiprocessing


def worker(procnum, return_dict):
    """worker function"""
    print(str(procnum) + " represent!")
    return_dict[procnum] = procnum


if __name__ == "__main__":
    manager = multiprocessing.Manager()
    return_dict = manager.dict()
    jobs = []
    for i in range(5):
        p = multiprocessing.Process(target=worker, args=(i, return_dict))
        jobs.append(p)
        p.start()

    for proc in jobs:
        proc.join()
    print(return_dict.values())

Using jQuery:

var a = [1,2,3];
var b = [2,3,4,5];
var c = $(b).not($(b).not(a));
alert(c);

The answer above has an incorrect assumption that the order of inclusion of the files matter. As the alertNumber function is not called until the alertOne function is called. As long as both files are included by time alertOne is called the order of the files does not matter:

[HTML]

<script type="text/javascript" src="file1.js"></script>
<script type="text/javascript" src="file2.js"></script>
<script type="text/javascript">
    alertOne( );
</script>

[JS]

// File1.js
function alertNumber( n ) {
    alert( n );
};
// File2.js
function alertOne( ) {
    alertNumber( "one" );
};
// Inline
alertOne( ); // No errors

Or it can be ordered like the following:

[HTML]

<script type="text/javascript" src="file2.js"></script>
<script type="text/javascript" src="file1.js"></script>
<script type="text/javascript">
    alertOne( );
</script>

[JS]

// File2.js
function alertOne( ) {
    alertNumber( "one" );
};
// File1.js
function alertNumber( n ) {
    alert( n );
};
// Inline
alertOne( ); // No errors

But if you were to do this:

[HTML]

<script type="text/javascript" src="file2.js"></script>
<script type="text/javascript">
    alertOne( );
</script>
<script type="text/javascript" src="file1.js"></script>

[JS]

// File2.js
function alertOne( ) {
    alertNumber( "one" );
};
// Inline
alertOne( ); // Error: alertNumber is not defined
// File1.js
function alertNumber( n ) {
    alert( n );
};

It only matters about the variables and functions being available at the time of execution. When a function is defined it does not execute or resolve any of the variables declared within until that function is then subsequently called.

Inclusion of different script files is no different from the script being in that order within the same file, with the exception of deferred scripts:

<script type="text/javascript" src="myscript.js" defer="defer"></script>

then you need to be careful.

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

Hello every one thanks for the help below is the working code for my question

$("#TableView tr.item").each(function() { 
    var quantity1=$(this).find("input.name").val(); 
    var quantity2=$(this).find("input.id").val(); 
});

Well I tried Nathan Koop's answer and it didn't work for me. I changed it to the following and it did work:

SELECT COUNT(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'table_name'

It also didn't work if I put USE 'database_name' nor WHERE table_catalog = 'database_name' AND table_name' = 'table_name'. I actually will be happy to know why.

Chances that you already got the source code with the JDK, it is matter of finding where it is. In case, JDK folder doesn't contain the source code:

sudo apt-get install openjdk-7-source

OSX Folks, search in homebrew formulas.

In ubuntu, the command above would put your souce file under: /usr/lib/jvm/openjdk-7/

One needs to be somewhat careful, since the Windows batch command:

for /f "delims=" %%a in ('command') do @set theValue=%%a

does not have the same semantics as the Unix shell statement:

theValue=`command`

Consider the case where the command fails, causing an error.

In the Unix shell version, the assignment to "theValue" still occurs, any previous value being replaced with an empty value.

In the Windows batch version, it's the "for" command which handles the error, and the "do" clause is never reached -- so any previous value of "theValue" will be retained.

To get more Unix-like semantics in Windows batch script, you must ensure that assignment takes place:

set theValue=
for /f "delims=" %%a in ('command') do @set theValue=%%a

Failing to clear the variable's value when converting a Unix script to Windows batch can be a cause of subtle errors.

You can use the default traceroute command for this purpose, then there will be nothing to install.

traceroute -T -p 9100 <IP address/hostname>

The -T argument is required so that the TCP protocol is used instead of UDP.

In the rare case when traceroute isn't available, you can also use ncat.

nc -Czvw 5 <IP address/hostname> 9100

I would rather create a function like TryParse or use T-SQL TRY-CATCH block to get what you wanted.

ISNUMERIC doesn't always work as intended. The code given before will fail if you do:

SET @text = '$'

$ sign can be converted to money datatype, so ISNUMERIC() returns true in that case. It will do the same for '-' (minus), ',' (comma) and '.' characters.

This should work as well:

DELETE FROM [table] 
INNER JOIN (
    SELECT [id] 
    FROM (
        SELECT [id] 
        FROM [table] 
        ORDER BY [id] DESC
        LIMIT N
    ) AS Temp
) AS Temp2 ON [table].[id] = [Temp2].[id]

The easiest way to solve this in pure HTML is to use the <base href="…"> element like so:

<base href="http://localhost/mywebsite/" />

Then all of the URLs in your HTML can just be this:

<a href="images/example.png">Link To Image</a>

Just change the <base href="…"> to match your server. The rest of the HTML paths will just fall in line and will be appended to that.

Consider using a the transform: rotate(-90deg) style on an element. See http://www.w3schools.com/cssref/css3_pr_transform.asp

Example, In your css

.verticaltext_content {
  position: relative;
  transform: rotate(-90deg);
  right:90px;   //These three positions need adjusting
  bottom:150px; //based on your actual chart size
  width:200px;
}

Add a space fudge factor to the Y Axis scale so the text has room to render in your javascript.

scaleLabel: "      <%=value%>"

Then in your html after your chart canvas put something like...

<div class="text-center verticaltext_content">Y Axis Label</div>

It is not the most elegant solution, but worked well when I had a few layers between the html and the chart code (using angular-chart and not wanting to change any source code).

There is also the Simple Print package, which uses enscript to do the actual printing.

Similar to kenorb's answer, open the palette (ctrl/cmd+shift+p), "Install package", "Simple Print Function"

you MUST install enscript and here is how:

Here's the cheat sheet on the commands:

• hg update changes your working copy parent revision and also changes the file content to match this new parent revision. This means that new commits will carry on from the revision you update to.

• hg revert changes the file content only and leaves the working copy parent revision alone. You typically use hg revert when you decide that you don't want to keep the uncommited changes you've made to a file in your working copy.

• hg branch starts a new named branch. Think of a named branch as a label you assign to the changesets. So if you do hg branch red, then the following changesets will be marked as belonging on the "red" branch. This can be a nice way to organize changesets, especially when different people work on different branches and you later want to see where a changeset originated from. But you don't want to use it in your situation.

If you use hg update --rev 38, then changesets 39–45 will be left as a dead end — a dangling head as we call it. You'll get a warning when you push since you will be creating "multiple heads" in the repository you push to. The warning is there since it's kind of impolite to leave such heads around since they suggest that someone needs to do a merge. But in your case you can just go ahead and hg push --force since you really do want to leave it hanging.

If you have not yet pushed revision 39-45 somewhere else, then you can keep them private. It's very simple: with hg clone --rev 38 foo foo-38 you will get a new local clone that only contains up to revision 38. You can continue working in foo-38 and push the new (good) changesets you create. You'll still have the old (bad) revisions in your foo clone. (You are free to rename the clones however you want, e.g., foo to foo-bad and foo-38 to foo.)

Finally, you can also use hg revert --all --rev 38 and then commit. This will create a revision 46 which looks identical to revision 38. You'll then continue working from revision 46. This wont create a fork in the history in the same explicit way as hg update did, but on the other hand you wont get complains about having multiple heads. I would use hg revert if I were collaborating with others who have already made their own work based on revision 45. Otherwise, hg update is more explicit.

You are dividing by rr which may be 0.0. Check if rr is zero and do something reasonable other than using it in the denominator.

you can pass multiple params in url like

http://localhost:2000/custom?brand=dell&limit=20&price=20000&sort=asc

and in order to get this query fields , you can use map like

    @RequestMapping(method = RequestMethod.GET, value = "/custom")
    public String controllerMethod(@RequestParam Map<String, String> customQuery) {

        System.out.println("customQuery = brand " + customQuery.containsKey("brand"));
        System.out.println("customQuery = limit " + customQuery.containsKey("limit"));
        System.out.println("customQuery = price " + customQuery.containsKey("price"));
        System.out.println("customQuery = other " + customQuery.containsKey("other"));
        System.out.println("customQuery = sort " + customQuery.containsKey("sort"));

        return customQuery.toString();
    }

I had a same issue. This solution works for me from WebDriverDoku:

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("someid")));

in ubuntu 19.04, we found it on

I generally try to avoid expressions with ng-show and ng-hide as they were designed as booleans, not conditionals. If I need both conditional and boolean logic, I prefer to put in the conditional logic using ng-if as the first check, then add in an additional check for the boolean logic with ng-show and ng-hide

Howerver, if you want to use a conditional for ng-show or ng-hide, here is a link with some examples: Conditional Display using ng-if, ng-show, ng-hide, ng-include, ng-switch

To manipulate data you actually need executeUpdate() rather than executeQuery().

Here's an extract from the executeUpdate() javadoc which is already an answer at its own:

Executes the given SQL statement, which may be an INSERT, UPDATE, or DELETE statement or an SQL statement that returns nothing, such as an SQL DDL statement.

Why not ?

Just modify your Main-Class to receive arguments and act upon the argument.

public class wiki2txt {

    public static void main(String[] args) {

          String fileName = args[0];

          // Use FileInputStream, BufferedReader etc here.

    }
}

Specify the full path in the commandline.

java -jar wiki2txt /home/bla/enwiki-....xml

The following works fine for me in Excel 2007. It is simple, and performs a full copy (retains all formatting, etc.):

Sheets("Sheet1").Columns(1).Copy Destination:=Sheets("Sheet2").Columns(2)

"Columns" returns a Range object, and so this is utilizing the "Range.Copy" method. "Destination" is an option to this method - if not provided the default is to copy to the paste buffer. But when provided, it is an easy way to copy.

As when manually copying items in Excel, the size and geometry of the destination must support the range being copied.

I believe this is controlled by the css color property applied to the element.

The model has a save method, which saves all the details necessary to reconstitute the model. An example from the keras documentation:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

I resolved my issue by following correct directions on pyodbc - Building wiki which states:

On Linux, pyodbc is typically built using the unixODBC headers, so you will need unixODBC and its headers installed. On a RedHat/CentOS/Fedora box, this means you would need to install unixODBC-devel:

yum install unixODBC-devel

I struggled with this for some time trying unsuccessfully the various suggestions in this and other threads.

However, in another thread (not sure where) someone suggested that using a negative constraint on the UIScrollView worked for him.

So I tried various combinations of constraints with inconsistent results. What eventually worked for me was to add leading and trailing constraints of -32 to the scrollview and add an (invisible) textview with a width of 320 (and centered).

Byte is not a standard type in C/C++, so it is represented by char.

An advantage of this is that you can treat a basic_string as a byte array allowing for safe storage and function passing. This will help you avoid the memory leaks and segmentation faults you might encounter when using the various forms of char[] and char*.

For example, this creates a string as a byte array of null values:

typedef basic_string<unsigned char> u_string;

u_string bytes = u_string(16,'\0');

This allows for standard bitwise operations with other char values, including those stored in other string variables. For example, to XOR the char values of another u_string across bytes:

u_string otherBytes = "some more chars, which are just bytes";
for(int i = 0; i < otherBytes.length(); i++)
    bytes[i%16] ^= (int)otherBytes[i];

Implementation is up to compiler developers.

If your question is "what will happen with such declaration" - compiler will set first array element to the value you've provided (0) and all others will be set to zero because it is a default value for omitted array elements.

Use order by like this:

return User::orderBy('name', 'DESC')
    ->orderBy('surname', 'DESC')
    ->orderBy('email', 'DESC')
    ...
    ->get();

The problem is the linker is looking for libmagic.so but you only have libmagic.so.1

A quick hack is to symlink libmagic.so.1 to libmagic.so

I've achieved the same thing before by using subqueries. So if your original table was called StoreCountsByWeek, and you had a separate table that listed the Store IDs, then it would look like this:

SELECT StoreID, 
    Week1=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=1),
    Week2=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=2),
    Week3=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=3)
FROM Store
ORDER BY StoreID

One advantage to this method is that the syntax is more clear and it makes it easier to join to other tables to pull other fields into the results too.

My anecdotal results are that running this query over a couple of thousand rows completed in less than one second, and I actually had 7 subqueries. But as noted in the comments, it is more computationally expensive to do it this way, so be careful about using this method if you expect it to run on large amounts of data .

Accessing CSS property & manipulating is quite easy using .css(). For example, to change single property:

$("selector").css('top', '50px');

I had a similar problem to solve, here is a simple solution of how to pass variables to template files, the trick is to write the template file taking advantage of the variable. You need to create a dictionary (list is also possible), which holds the set of variables corresponding to each of the file. Then within the template file access them.

see below:

the template file: test_file.j2
# {{ ansible_managed }} created by [email protected]

{% set dkey  = (item | splitext)[0]  %}
{% set fname = test_vars[dkey].name  %}
{% set fip   = test_vars[dkey].ip    %}
{% set fport = test_vars[dkey].port  %}
filename: {{ fname }}
ip address: {{ fip }}
port: {{ fport }}

Ians Answer is good, but you should use const instead of let for the key because it never gets updated.

for (const key in myDictionary) {
    let value = myDictionary[key];
    // Use `key` and `value`
}

You can use a closure for this:

func doif(b bool, f1, f2 func()) {
    switch{
    case b:
        f1()
    case !b:   
        f2()
    }
}

func dothis() { fmt.Println("Condition is true") }

func dothat() { fmt.Println("Condition is false") }

func main () {
    condition := true
    doif(condition, func() { dothis() }, func() { dothat() })
}

The only gripe I have with the closure syntax in Go is there is no alias for the default zero parameter zero return function, then it would be much nicer (think like how you declare map, array and slice literals with just a type name).

Or even the shorter version, as a commenter just suggested:

func doif(b bool, f1, f2 func()) {
    switch{
    case b:
        f1()
    case !b:   
        f2()
    }
}

func dothis() { fmt.Println("Condition is true") }

func dothat() { fmt.Println("Condition is false") }

func main () {
    condition := true
    doif(condition, dothis, dothat)
}

You would still need to use a closure if you needed to give parameters to the functions. This could be obviated in the case of passing methods rather than just functions I think, where the parameters are the struct associated with the methods.

A variant of Nick Berardi's answer that avoids a branch:

int q = records / recordsPerPage, r = records % recordsPerPage;
int pageCount = q - (-r >> (Integer.SIZE - 1));

Note: (-r >> (Integer.SIZE - 1)) consists of the sign bit of r, repeated 32 times (thanks to sign extension of the >> operator.) This evaluates to 0 if r is zero or negative, -1 if r is positive. So subtracting it from q has the effect of adding 1 if records % recordsPerPage > 0.

SOAP – "Simple Object Access Protocol"

SOAP is a slight of transferring messages, or little amounts of information over the Internet. SOAP messages are formatted in XML and are typically sent controlling HTTP.

REST – "REpresentational State Transfer"

REST is a rudimentary proceed of eventuality and receiving information between fan and server and it doesn't have unequivocally many standards defined. You can send and accept information as JSON, XML or even plain text. It's light weighted compared to SOAP.

Void is the equivalent of Visual Basic's Sub.

Here's a three-step, somewhat minimalist version of ThorSummoner's answer for the sake of clarity. It doesn't quite do what I want (I'll explain at the bottom), but it works okay.

Step 1: Make directory and setup.py

filepath_to/project_name/
    setup.py

In setup.py, write:

import setuptools

setuptools.setup(name='project_name')

Step 2: Install this directory as a package

Run this code in console:

python -m pip install --editable filepath_to/project_name

Instead of python, you may need to use python3 or something, depending on how your python is installed. Also, you can use -e instead of --editable.

Now, your directory will look more or less like this. I don't know what the egg stuff is.

filepath_to/project_name/
    setup.py
    test_3.egg-info/
        dependency_links.txt
        PKG-INFO
        SOURCES.txt
        top_level.txt

This folder is considered a python package and you can import from files in this parent directory even if you're writing a script anywhere else on your computer.

Step 3. Import from above

Let's say you make two files, one in your project's main directory and another in a sub directory. It'll look like this:

filepath_to/project_name/
    top_level_file.py
    subdirectory/
        subfile.py

    setup.py          |
    test_3.egg-info/  |----- Ignore these guys
        ...           |

Now, if top_level_file.py looks like this:

x = 1

Then I can import it from subfile.py, or really any other file anywhere else on your computer.

# subfile.py  OR  some_other_python_file_somewhere_else.py

import random # This is a standard package that can be imported anywhere.
import top_level_file # Now, top_level_file.py works similarly.

print(top_level_file.x)

This is different than what I was looking for: I hoped python had a one-line way to import from a file above. Instead, I have to treat the script like a module, do a bunch of boilerplate, and install it globally for the entire python installation to have access to it. It's overkill. If anyone has a simpler method than doesn't involve the above process or importlib shenanigans, please let me know.

Use this below code

 border:2px soild #eee;

 margin: 15px 15px;
 -webkit-box-shadow: 2px 3px 8px #eee;
-moz-box-shadow: 2px 3px 8px #eee;
box-shadow: 2px 3px 8px #eee;

Explanation:-

box-shadow requires you to set the horizontal & vertical offsets, you can then optionally set the blur and colour, you can also choose to have the shadow inset instead of the default outset. Colour can be defined as hex or rgba.

box-shadow : inset/outset h-offset v-offset blur spread color;

Explanation of the values...

inset/outset -- whether the shadow is inside or outside the box. If not specified it will default to outset.

h-offset -- the horizontal offset of the shadow (required value)

v-offset -- the vertical offset of the shadow (required value)

blur -- as it says, the blur of the shadow

spread -- moves the shadow away from the box equally on all sides. A positive value causes the shadow to expand, negative causes it to contract. Though this value isn't often used, it is useful with multiple shadows.

color -- as it says, the color of the shadow

Usage

box-shadow:2px 3px 8px #eee; a gray shadow with a horizontal outset of 2px, vertical of 3px and a blur of 8px

If you drop the "child" table first, the foreign key will be dropped as well. If you attempt to drop the "parent" table first, you will get an "Could not drop object 'a' because it is referenced by a FOREIGN KEY constraint." error.

I know this question has a good answer with 't', but thought I would add another solution.

$first = date("Y-m-d", strtotime("first day of this month"));
$last = date("Y-m-d", strtotime("last day of this month"));

Yes there is. It is wrong. It won't work because it is wrong. Most browsers will only see one form.
