Apparently there is a Powershell bug in Windows 10 version 1511.

None of the fixes listed here worked for me. (or only worked temporarily)

I fixed it (both in VS2013 and VS2015) by installing version 1607. It can be downloaded here: Windows 10 Anniversary Update.

Nuget issue: https://github.com/NuGet/Home/issues/3352

You will see it only when the file is open. When you'll close the file in Visual Studio the warnings goes away

http://nuget.codeplex.com/discussions/261638

It's now possible to control which folder the packages are installed into.

http://nuget.codeplex.com/workitem/215

Edit: See Phil Haack's comment on Dec 10 2010 at 11:45 PM (in the work item/the link above). The support is partially implemented in 1.0, but is not documented.

According to @dfowler: Add a nuget.config file next to the solution with this:

<settings>
<repositoryPath>{some path here}</repositoryPath>
</settings>

There is a nuget package for creating the package folder override.

Update for version 2.1

As Azat commented, there is now official documentation on how to control the package locations. The release notes for 2.1 specifies the following configuration in a nuget.config file (see the release notes for a description of valid places to put the config files and how the hierarchical configuration model works):

<configuration>
  <config>
    <add key="repositoryPath" value="C:\thePathToMyPackagesFolder" />
  </config>
  ... 
</configuration>

This would change the packages folder for the configuration level you put the file in (solution if you put it in the solution directory, project in project directory and so on). Note that the release notes state:

[...] if you have an existing packages folder underneath your solution root, you will need to delete it before NuGet will place packages in the new location.

Package Manager console (Visual Studio, Tools > NuGet Package Manager > Package Manager Console): Run the Update-Package -reinstall -ProjectName command where is the name of the affected project as it appears in Solution Explorer. Use Update-Package -reinstall by itself to restore all packages in the solution. See Update-Package. You can also reinstall a single package, if desired.

from https://docs.microsoft.com/en-us/nuget/quickstart/restore

Go to -> Tools -> Extensions and Updates and uninstall NuGet package manager.. restart visual studio and reinstall it.... every thing will set to normal

To obtain the current stable version of the NuGet package use:

https://www.nuget.org/api/v2/package/{packageID}

I updated my package and even reinstalled it - but I was still getting the exact same error as the OP mentioned. I manually edited the referenced dll by doing the following.

I removed the newtonsoft.json.dll from my reference, then manually deleted the .dll from the bin directoy. Then i manually copied the newtonsoft.json.dll from the nuget package folder into the project bin, then added the reference by browsing to the .dll file.

Now my project builds again.

Use nmp configuration file (add it to your web project) then add the needed packages in the same way we did using bower.json and save. Visual studio will download and install it. You'll find the package the under the nmp node of your project.

By using the Nuget Package Manager UI as mentioned above it helps to uninstall the nuget package first. I always have problems when going back on a nuget package version if I don't uninstall first. Some references are not cleaned properly. So I suggest the following workflow when installing an old nuget package through the Nuget Package Manager:

1. Selected your nuget server / source
2. Find and select the nuget package your want to install an older version
3. Uninstall current version
4. Click on the install drop-down > Select older version > Click Install

Good Luck :)

I created a folder named '.nuget' in solution root folder Then added file 'NuGet.Config' in this folder with following content

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<solution>
 <add key="disableSourceControlIntegration" value="true" />
</solution>
</configuration>

Then created file '.nuGet.targets' as below $(MSBuildProjectDirectory)..\

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

Menu Tools ? Options ? Package Manager

Give a name and folder location. Click OK. Drop your NuGet package files in that folder.

Go to your Project, right click and select "Manage NuGet Packages" and select your new package source.

Here is the documentation.

You can also find a copy of the nuspec.xsd here as it seems to no longer be available:

NOTE: This is mentioned in the question but restarting Visual Studio fixes the issue in most cases.

Updating Visual Studio to 'Update 2' got it working again.

Tools -> Extensions and Updates ->Visual Studio Update 2

As mentioned in the question and the link i posted therein, I'd already updated NuGet Package Manager to 3.4.4 prior to this and restarted to no avail, so I don't know if the combination of both these actions worked.

None of the above solutions worked for me, I found an article that explained the issue. The security protocols on the system were deprecated and therefore displayed an error message that no match was found for the ProviderPackage.

Here is a the basic steps for upgrading your security protocols:

Run both cmdlets to set .NET Framework strong cryptography registry keys. After that, restart PowerShell and check if the security protocol TLS 1.2 is added. As of last, install the PowerShellGet module.

The first cmdlet is to set strong cryptography on 64 bit .Net Framework (version 4 and above).

[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
1
[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
The second cmdlet is to set strong cryptography on 32 bit .Net Framework (version 4 and above).

[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
1
[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
Restart Powershell and check for supported security protocols.

[PS] C:\>[Net.ServicePointManager]::SecurityProtocol
Tls, Tls11, Tls12
1
2
[PS] C:\>[Net.ServicePointManager]::SecurityProtocol
Tls, Tls11, Tls12
Run the command Install-Module PowershellGet -Force and press Y to install NuGet provider, follow with Enter.

I have to agree with @Juri that the vastly popular answer by jmfenoll is not complete. In the case of broken references, I submit that most of the time you do not want to update to the latest package, but only fix your references to the current versions that you happen to be using. And Juri provided a handy function Sync-References to do just that.

But we can go just a bit further, allowing the flexibility to filter by project as well as package:

function Sync-References([string]$PackageId, [string]$ProjectName) {
    get-project -all | 
    Where-Object { $_.name -match $ProjectName } |
    ForEach-Object {
        $proj = $_ ;
        Write-Output ('Project: ' + $proj.name)
        Get-Package -project $proj.name |
        Where-Object { $_.id -match $PackageId } |
        ForEach-Object { 
            Write-Output ('Package: ' + $_.id)
            uninstall-package -projectname $proj.name -id $_.id -version $_.version -RemoveDependencies -force
            install-package -projectname $proj.name -id $_.id -version $_.version
        }
    }
}

The provider is bundled with PowerShell>=6.0.

If all you need is a way to install a package from a file, just grab the .msi installer for the latest version from the github releases page, copy it over to the machine, install it and use it.

Closing and re-opening VS2015 resolves the issue.

It seems that in some cases, simply reloading the affected project will work.

Sometimes something strange happens and using Visual Studio to automatically restore doesn't work. In that case you can use the NuGet Package Manager Console. That is opened within Visual Studio from Tools -> NuGet Package Manager -> Package Manager Console. The commands within the console are simple. And to get context help while typing a command just press the button and it will give you all options that start with the letters you're typing. So if a package isn't installed, for example log4net, type the following command:

Install-Package log4net

You can do a whole lot more, like specify the version to install, update a package, uninstall a package, etc.

I had to use the console to help me when Visual Studio was acting like a weirdo.

I believe the first thing you need to do is enable the package restore feature. See also here. This is done at the solution (not project) level.

But that won't get you all the way -- I ran into a similar issue after having enabled the restore feature. (VS2013, NuGet 2.8.)

It turned out I had (unintentionally) committed the packages to source control when I committed the project -- but Visual Studio (and the source control plugin) had helpfully ignored the binaries when performing the check-in.

The problem arose when I created a release branch. My local copy of the dev/main/trunk branch had the binaries, because that's where I had originally installed/downloaded the packages.
However, in the new release branch,

• the package folders and .nupkg files were all there -- so NuGet didn't think there was anything to restore;
• but at the same time, none of the DLLs were present -- i.e. the third-party references were missing -- so I couldn't build.

I deleted all the package folders in $(SolutionDir)/packages (under the release branch) and then ran a full rebuild, and this time the build succeeded.
... and then of course I went back and removed the package folders from source control (in the trunk and release branch). I'm not clear (yet) on whether the repositories.config file should be removed as well.

Many of the components installed for you by the project templates -- at least for web projects -- are NuGet packages. That is, this issue is not limited to packages you've added.
So enable package restore immediately after creating the project/solution, and before you perform an initial check-in, clear the packages folder (and make sure you commit the .nuget folder to source control).

Disclaimer: I saw another answer here on SO which indicated that clearing the packages folder was part of the resolution. That put me on the right track, so I'd like to give the author credit, but I can no longer locate that question/answer. I'll post an edit if I stumble across it.

I'd also note that Update-Package -reinstall will modify the .sln and .csproj/.vbproj files. At least that's what it did in my case. Which IMHO makes this option much less attractive.

The packages you installed introduced dependencies to version 5.2.3.0 dll's as user Bracher showed above. Microsoft.AspNet.WebApi.Cors is an example package. The path I take is to update the MVC project proir to any package installs:

Install-Package Microsoft.AspNet.Mvc -Version 5.2.3

https://www.nuget.org/packages/microsoft.aspnet.mvc

Mine worked when I copied packages folder along with solution file and project folder. I just did not copy packages folder from previous place.

Cause of this defect: you have to remove the injected Nuget in file explorer. Solution: Once you remove that Nuget in your system, then remove from following location. select Tool=>Options=>NuGet Package Manager=> Package Sources then uncheck Microsoft Visual Studio Offline Packages Option

Note that dnx has a different cache for feeding HTTP results:

Microsoft .NET Development Utility Clr-x86-1.0.0-rc1-16231
   CACHE https://www.nuget.org/api/v2/
   CACHE http://192.168.148.21/api/odata/

Which you can clear with

dnu clear-http-cache

Now we just need to find out what the command will be on the new dotnet CLI tool.

...and here it is:

dotnet restore --no-cache

One NuGet package can reference another NuGet package. So, please be very careful about inter-package dependencies. I just uninstalled a Google map package and it subsequently uninstalled underlying packages like Newtonsoft, Entity Framework, etc.

So, manually deleting particular package from packages folder would be safer.

Just in case you are using the https version of nuget (https://www.nuget.org), be aware that you have to set the values with https.

• https_proxy
• https_proxy.user
• https_proxy.password

Try the following:

Uninstall-Package Newtonsoft.Json -Force

Followed by:

Install-Package Newtonsoft.Json -Version <press tab key for autocomplete>

This problem appeared for me when I was creating folders in the filesystem (not in my solution) and moved some projects around.

Turns out that the package paths are relative from the csproj files. So I had to change the "HintPath" of my references:

<Reference Include="EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL">
    <HintPath>..\packages\EntityFramework.6.1.3\lib\net45\EntityFramework.dll</HintPath>
    <Private>True</Private>
</Reference>

To:

<Reference Include="EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL">
    <HintPath>..\..\packages\EntityFramework.6.1.3\lib\net45\EntityFramework.dll</HintPath>
    <Private>True</Private>
</Reference>

Notice the double "..\" in 'HintPath'.

I also had to change my error conditions, for example I had to change:

<Error Condition="!Exists('..\packages\Microsoft.Net.Compilers.1.1.1\build\Microsoft.Net.Compilers.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Microsoft.Net.Compilers.1.1.1\build\Microsoft.Net.Compilers.props'))" />

To:

<Error Condition="!Exists('..\..\packages\Microsoft.Net.Compilers.1.1.1\build\Microsoft.Net.Compilers.props')" Text="$([System.String]::Format('$(ErrorText)', '..\..\packages\Microsoft.Net.Compilers.1.1.1\build\Microsoft.Net.Compilers.props'))" />

Again, notice the double "..\".

I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.

I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.

1. Go to the "Manage NuGet Packages"
2. Select the Installed Package "Microsoft ASP.NET Web API 2.1"
3. Click Manage and check the projects that I manually added before.

I had a test project that references 2 other projects that each referenced different versions (in different locations) of the same dll. This confused the compiler.

It took me some time to figure out the whole picture and I'd like to share here.

Visual Studio has two approaches to use package restore: Automatic Package Restore and MSBuild-Integrated package restore. The 'MSBuild-Integrated Package Restore' restores packages DURING the building process that might cause issues in some scenarios. The 'Automatic Package Restore' is the recommended approach by the NuGet team.

There are several steps to to make 'Automatic Package Restore' work:

1. In Visual Studio, Tools -> Extensions and Updates, Upgrade NuGet if there is a newer version (Version 2.7 or later)

2. If you use TFS, in your solution's .nuget folder, remove the NuGet.exe and NuGet.targes files. Then edit NuGet.Config to not check in NuGet packages:

   <configuration>  
     <solution>  
       <add key="disableSourceControlIntegration" value="true" />  
     </solution>  
   </configuration> 
   

   If you checked in the solution's packages folder to TFS before, delete the folder and check in the deletion of package folder deletion.

   If you don't use TFS, delete the .nuget folder.

3. In each project file (.csproj or .vbproj) in your solution, remove the line that references NuGet.targets file. The reference looks like this:

   <Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
   

   Remove this line in every project file in your solution.

4. In Visual Studio menu, either through

   Tools -> Options -> Package Manager -> General or Tools -> NuGet Package Manager -> Package Manager Settings

   please enable the following two options 1) 'Allow NuGet to download missing packages' 2) 'Automatically check for missing packages during build in Visual Studio'

5. Test your package restore configuration by the following steps

   • Save your solution and close Visual Studio
   • Delete your solution's packages folder
   • Start Visual Studio, open your solution and rebuild it.

For me, I had ~6 different Nuget packages to update and when I selected Microsoft.AspNetCore.All first, I got the referenced error.

I started at the bottom and updated others first (EF Core, EF Design Tools, etc), then when the only one that was left was Microsoft.AspNetCore.All it worked fine.

This was resolved by installing the latest NuGet Package Manager:

https://visualstudiogallery.msdn.microsoft.com/4ec1526c-4a8c-4a84-b702-b21a8f5293ca

Don't forget to restart Visual Studio.

You can also use the NuGet command line, by specifying a local host as part of an install. For example if your package is stored in the current directory

nuget install MyPackage -Source %cd% -OutputDirectory packages

will unpack it into the target directory.

import org.apache.commons.lang3.StringUtils;

...
StringUtils.substringBefore("Grigory Kislin", " ")

Swift 5.2

The only method I found to work and refresh a view dynamically where the visibility of buttons had changed was:-

viewWillAppear(true)

This may be a bad practice but hopefully somebody will leave a comment.

You can also use:

PWD=$(pwd)
source "$PWD/inc.sh"

private void SortGridGenerico< T >(
          ref List< T > lista       
    , SortDirection sort
    , string propriedadeAOrdenar)
{

    if (!string.IsNullOrEmpty(propriedadeAOrdenar)
    && lista != null
    && lista.Count > 0)
    {

        Type t = lista[0].GetType();

        if (sort == SortDirection.Ascending)
        {

            lista = lista.OrderBy(
                a => t.InvokeMember(
                    propriedadeAOrdenar
                    , System.Reflection.BindingFlags.GetProperty
                    , null
                    , a
                    , null
                )
            ).ToList();
        }
        else
        {
            lista = lista.OrderByDescending(
                a => t.InvokeMember(
                    propriedadeAOrdenar
                    , System.Reflection.BindingFlags.GetProperty
                    , null
                    , a
                    , null

composer require phpmailer/phpmailer

The next on your sendmail.php file just require the following

# use namespace
use PHPMailer\PHPMailer\PHPMailer;

# require php mailer
require_once "../vendor/autoload.php";

//PHPMailer Object
$mail = new PHPMailer;

//From email address and name
$mail->From = "[email protected]";
$mail->FromName = "Full Name";

//To address and name
$mail->addAddress("[email protected]", "Recepient Name");
$mail->addAddress("[email protected]"); //Recipient name is optional

//Address to which recipient will reply
$mail->addReplyTo("[email protected]", "Reply");

//CC and BCC
$mail->addCC("[email protected]");
$mail->addBCC("[email protected]");

//Send HTML or Plain Text email
$mail->isHTML(true);

$mail->Subject = "Subject Text";
$mail->Body = "<i>Mail body in HTML</i>";
$mail->AltBody = "This is the plain text version of the email content";

if(!$mail->send()) 
{
    echo "Mailer Error: " . $mail->ErrorInfo;
} 
else 
{
    echo "Message has been sent successfully";
}

This can be configure how ever you like..

Maybe I'm not understanding the question but here is my simple solution that works -

# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)

# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty

I agree that labels are not automatically updated but can easily be updated with the

<label name>.config(text="<new text>" + str(<variable name>))

That just needs to be included in your code after the variable is updated.

Popen.communicate() documentation:

Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.

Replacing os.popen*

    pipe = os.popen(cmd, 'w', bufsize)
    # ==>
    pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin

Warning Use communicate() rather than stdin.write(), stdout.read() or stderr.read() to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

So your example could be written as follows:

from subprocess import Popen, PIPE, STDOUT

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=STDOUT)    
grep_stdout = p.communicate(input=b'one\ntwo\nthree\nfour\nfive\nsix\n')[0]
print(grep_stdout.decode())
# -> four
# -> five
# ->

On Python 3.5+ (3.6+ for encoding), you could use subprocess.run, to pass input as a string to an external command and get its exit status, and its output as a string back in one call:

#!/usr/bin/env python3
from subprocess import run, PIPE

p = run(['grep', 'f'], stdout=PIPE,
        input='one\ntwo\nthree\nfour\nfive\nsix\n', encoding='ascii')
print(p.returncode)
# -> 0
print(p.stdout)
# -> four
# -> five
# -> 

If you don't want an array then how about an object?

Since many browsers block popups by default and popups are really ugly, I recommend using lightbox or thickbox.

They are prettier and are not popups. They are extra HTML markups that are appended to your document's body with the appropriate CSS content.

NOW() normally works in SQL statements and returns the date and time. Check if your database field has the correct type (datetime). Otherwise, you can always use the PHP date() function and insert:

date('Y-m-d H:i:s')

But I wouldn't recommend this.

Change your gradle version in project setting: If you are using mac,click File->Project structure,then change gradle version,here:

And check your build.gradle of project,change dependency of gradle,like this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'
    }
}

I've got the following in my .emacs:

(defun fontify-frame (frame)
  (set-frame-parameter frame 'font "Monospace-11"))

;; Fontify current frame
(fontify-frame nil)
;; Fontify any future frames
(push 'fontify-frame after-make-frame-functions) 

You can subsitute any font of your choosing for "Monospace-11". The set of available options is highly system-dependent. Using M-x set-default-font and looking at the tab-completions will give you some ideas. On my system, with Emacs 23 and anti-aliasing enabled, can choose system fonts by name, e.g., Monospace, Sans Serif, etc.

Use @Kristian Antonsen's answer, or you can use:

$('button').click(function() {
    preventDefault();
    captureForm();
});

There is one way I know how to achieve a strictly* one-to-one relationship without using triggers, computed columns, additional tables, or other 'exotic' tricks (only foreign keys and unique constraints), with one small caveat.

I will borrow the chicken-and-the-egg concept from the accepted answer to help me explain the caveat.

It is a fact that either a chicken or an egg must come first (in current DBs anyway). Luckily this solution does not get political and does not prescribe which has to come first - it leaves it up to the implementer.

The caveat is that the table which allows a record to 'come first' technically can have a record created without the corresponding record in the other table; however, in this solution, only one such record is allowed. When only one record is created (only chicken or egg), no more records can be added to any of the two tables until either the 'lonely' record is deleted or a matching record is created in the other table.

Solution:

Add foreign keys to each table, referencing the other, add unique constraints to each foreign key, and make one foreign key nullable, the other not nullable and also a primary key. For this to work, the unique constrain on the nullable column must only allow one null (this is the case in SQL Server, not sure about other databases).

CREATE TABLE dbo.Egg (
    ID int identity(1,1) not null,
    Chicken int null,
    CONSTRAINT [PK_Egg] PRIMARY KEY CLUSTERED ([ID] ASC) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE dbo.Chicken (
    Egg int not null,
    CONSTRAINT [PK_Chicken] PRIMARY KEY CLUSTERED ([Egg] ASC) ON [PRIMARY]
) ON [PRIMARY]
GO
ALTER TABLE dbo.Egg  WITH NOCHECK ADD  CONSTRAINT [FK_Egg_Chicken] FOREIGN KEY([Chicken]) REFERENCES [dbo].[Chicken] ([Egg])
GO
ALTER TABLE dbo.Chicken  WITH NOCHECK ADD  CONSTRAINT [FK_Chicken_Egg] FOREIGN KEY([Egg]) REFERENCES [dbo].[Egg] ([ID])
GO
ALTER TABLE dbo.Egg WITH NOCHECK ADD CONSTRAINT [UQ_Egg_Chicken] UNIQUE([Chicken])
GO
ALTER TABLE dbo.Chicken WITH NOCHECK ADD CONSTRAINT [UQ_Chicken_Egg] UNIQUE([Egg])
GO

To insert, first an egg must be inserted (with null for Chicken). Now, only a chicken can be inserted and it must reference the 'unclaimed' egg. Finally, the added egg can be updated and it must reference the 'unclaimed' chicken. At no point can two chickens be made to reference the same egg or vice-versa.

To delete, the same logic can be followed: update egg's Chicken to null, delete the newly 'unclaimed' chicken, delete the egg.

This solution also allows swapping easily. Interestingly, swapping might be the strongest argument for using such a solution, because it has a potential practical use. Normally, in most cases, a one-to-one relationship of two tables is better implemented by simply refactoring the two tables into one; however, in a potential scenario, the two tables may represent truly distinct entities, which require a strict one-to-one relationship, but need to frequently swap 'partners' or be re-arranged in general, while still maintaining the one-to-one relationship after re-arrangement. If the more common solution were used, all data columns of one of the entities would have to be updated/overwritten for all pairs being re-arranged, as opposed to this solution, where only one column of foreign keys need to be re-arranged (the nullable foreign key column).

Well, this is the best I could do using standard constraints (don't judge :) Maybe someone will find it useful.

To test without copy elision and see you copy/move constructors/operators in action add "-fno-elide-constructors".

Even with no optimizations (-O0 ), GCC and Clang will still do copy elision, which has the effect of skipping copy/move constructors in some cases. See this question for the details about copy elision.

However, in Clang 3.4 it does trigger a bug (an invalid temporary object without calling constructor), which is fixed in 3.5.

I was having the same issue and this works excellently.

Multiline strings are a current part of JavaScript (since ES6) and are supported in node.js v4.0.0 and newer.

console.log(text);

The call to InitializeComponent() (which is usually called in the default constructor of at least Window and UserControl) is actually a method call to the partial class of the control (rather than a call up the object hierarchy as I first expected).

This method locates a URI to the XAML for the Window/UserControl that is loading, and passes it to the System.Windows.Application.LoadComponent() static method. LoadComponent() loads the XAML file that is located at the passed in URI, and converts it to an instance of the object that is specified by the root element of the XAML file.

In more detail, LoadComponent creates an instance of the XamlParser, and builds a tree of the XAML. Each node is parsed by the XamlParser.ProcessXamlNode(). This gets passed to the BamlRecordWriter class. Some time after this I get a bit lost in how the BAML is converted to objects, but this may be enough to help you on the path to enlightenment.

Note: Interestingly, the InitializeComponent is a method on the System.Windows.Markup.IComponentConnector interface, of which Window/UserControl implement in the partial generated class.

Hope this helps!

You can use:

input[type=text]
{
 /*Styles*/
}

Define your common style attributes inside this. and for extra style you can add a class then.

use your Model class to get row values selected from datagrid like,

        XDocument xmlDoc = XDocument.Load(filepath);

        if (tablet_DG.SelectedValue == null)
        {
            MessageBox.Show("select any record from list..!", "select atleast one record", MessageBoxButton.OKCancel, MessageBoxImage.Warning);
        }
        else
        {
            try
            {
                string tabletID = "";

                 /*here i have used my model class named as TabletMode*/

                var row_list = (TabletModel)tablet_DG.SelectedItem; 
                 tabletID= row_list.TabletID;

                var items = from item in xmlDoc.Descendants("Tablet")
                            where item.Element("TabletID").Value == tabletID
                            select item;

                foreach (var item in items)
                {
                    item.SetElementValue("Instance",row_list.Instance);
                    item.SetElementValue("Database",row_list.Database);
                }

                xmlDoc.Save(filepath);
                MessageBox.Show("Details Updated..!"
                + Environment.NewLine + "TabletId: " +row_list.TabletID + Environment.NewLine
                + "Instance:" + row_list.Instance + Environment.NewLine + "Database:" + row_list.Database, "", MessageBoxButton.YesNoCancel, MessageBoxImage.Information);
            }

            catch (Exception ex)
            {
                MessageBox.Show(ex.StackTrace);
            }
        }

The CScout refactoring browser can detect superfluous include directives in C (unfortunately not C++) code. You can find a description of how it works in this journal article.

By default, plot does show axes, unless you've modified some settings. Try the following

hold on; % make sure no new plot window is created on every plot command
axes(); % produce plot window with axes
plot(% whatever your plot command is);
plot([0 10], [0 0], 'k-'); % plot the horizontal line

I also found that System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke() is not always dispatcher of target control, just as dotNet wrote in his answer. I didn't had access to control's own dispatcher, so I used Application.Current.Dispatcher and it solved the problem.

The difference between BCNF and 3NF

Using the BCNF definition

If and only if for every one of its dependencies X ? Y, at least one of the following conditions hold:

• X ? Y is a trivial functional dependency (Y ? X), or
• X is a super key for schema R

and the 3NF definition

If and only if, for each of its functional dependencies X ? A, at least one of the following conditions holds:

• X contains A (that is, X ? A is trivial functional dependency), or
• X is a superkey, or
• Every element of A-X, the set difference between A and X, is a prime attribute (i.e., each attribute in A-X is contained in some candidate key)

We see the following difference, in simple terms:

• In BCNF: Every partial key (prime attribute) can only depend on a superkey,

whereas

• In 3NF: A partial key (prime attribute) can also depend on an attribute that is not a superkey (i.e. another partial key/prime attribute or even a non-prime attribute).

Where

1. A prime attribute is an attribute found in a candidate key, and
2. A candidate key is a minimal superkey for that relation, and
3. A superkey is a set of attributes of a relation variable for which it holds that in all relations assigned to that variable, there are no two distinct tuples (rows) that have the same values for the attributes in this set.Equivalently a superkey can also be defined as a set of attributes of a relation schema upon which all attributes of the schema are functionally dependent. (A superkey always contains a candidate key/a candidate key is always a subset of a superkey. You can add any attribute in a relation to obtain one of the superkeys.)

That is, no partial subset (any non trivial subset except the full set) of a candidate key can be functionally dependent on anything other than a superkey.

A table/relation not in BCNF is subject to anomalies such as the update anomalies mentioned in the pizza example by another user. Unfortunately,

• BNCF cannot always be obtained, while
• 3NF can always be obtained.

3NF Versus BCNF Example

An example of the difference can currently be found at "3NF table not meeting BCNF (Boyce–Codd normal form)" on Wikipedia, where the following table meets 3NF but not BCNF because "Tennis Court" (a partial key/prime attribute) depends on "Rate Type" (a partial key/prime attribute that is not a superkey), which is a dependency we could determine by asking the clients of the database, the tennis club:

Today's Tennis Court Bookings (3NF, not BCNF)

Court   Start Time  End Time    Rate Type
------- ----------  --------    ---------
1       09:30       10:30       SAVER
1       11:00       12:00       SAVER
1       14:00       15:30       STANDARD
2       10:00       11:30       PREMIUM-B
2       11:30       13:30       PREMIUM-B
2       15:00       16:30       PREMIUM-A

The table's superkeys are:

S1 = {Court, Start Time}
S2 = {Court, End Time}
S3 = {Rate Type, Start Time}
S4 = {Rate Type, End Time}
S5 = {Court, Start Time, End Time}
S6 = {Rate Type, Start Time, End Time}
S7 = {Court, Rate Type, Start Time}
S8 = {Court, Rate Type, End Time}
ST = {Court, Rate Type, Start Time, End Time}, the trivial superkey

The 3NF problem: The partial key/prime attribute "Court" is dependent on something other than a superkey. Instead, it is dependent on the partial key/prime attribute "Rate Type". This means that the user must manually change the rate type if we upgrade a court, or manually change the court if wanting to apply a rate change.

• But what if the user upgrades the court but does not remember to increase the rate? Or what if the wrong rate type is applied to a court?

(In technical terms, we cannot guarantee that the "Rate Type" -> "Court" functional dependency will not be violated.)

The BCNF solution: If we want to place the above table in BCNF we can decompose the given relation/table into the following two relations/tables (assuming we know that the rate type is dependent on only the court and membership status, which we could discover by asking the clients of our database, the owners of the tennis club):

Rate Types (BCNF and the weaker 3NF, which is implied by BCNF)

Rate Type   Court   Member Flag
---------   -----   -----------
SAVER       1       Yes
STANDARD    1       No
PREMIUM-A   2       Yes
PREMIUM-B   2       No

Today's Tennis Court Bookings (BCNF and the weaker 3NF, which is implied by BCNF)

Member Flag     Court     Start Time   End Time
-----------     -----     ----------   --------
Yes             1         09:30        10:30
Yes             1         11:00        12:00
No              1         14:00        15:30
No              2         10:00        11:30
No              2         11:30        13:30
Yes             2         15:00        16:30

Problem Solved: Now if we upgrade the court we can guarantee the rate type will reflect this change, and we cannot charge the wrong price for a court.

(In technical terms, we can guarantee that the functional dependency "Rate Type" -> "Court" will not be violated.)

When using WebAPI, you should just return the Object rather than specifically returning Json, as the API will either return JSON or XML depending on the request.

I am not sure why your WebAPI is returning an ActionResult, but I would change the code to something like;

public IEnumerable<ListItems> GetAllNotificationSettings()
{
    var result = new List<ListItems>();
    // Filling the list with data here...

    // Then I return the list
    return result;
}

This will result in JSON if you are calling it from some AJAX code.

P.S WebAPI is supposed to be RESTful, so your Controller should be called ListItemController and your Method should just be called Get. But that is for another day.

I would do it like this:

Worksheets("EmployeeCosts").Range("B" & var1a).Formula = _
Replace("=SUM(H5:H{SOME_VAR})","{SOME_VAR}",var1a)

In case you have some more complex formula it will be handy

A little bit late, but you can request a higher quote here: https://support.google.com/youtube/contact/yt_api_form

Note: This code is untested

Define a record for your refCursor return type, call it rec. For example:

TYPE MyRec IS RECORD (col1 VARCHAR2(10), col2 VARCHAR2(20), ...);  --define the record
rec MyRec;        -- instantiate the record

Once you have the refcursor returned from your procedure, you can add the following code where your comments are now:

LOOP
  FETCH refCursor INTO rec;
  EXIT WHEN refCursor%NOTFOUND;
  dbms_output.put_line(rec.col1||','||rec.col2||','||...);
END LOOP;

I always prefer pre-increment, however ...

I wanted to point out that even in the case of calling the operator++ function, the compiler will be able to optimize away the temporary if the function gets inlined. Since the operator++ is usually short and often implemented in the header, it is likely to get inlined.

So, for practical purposes, there likely isn't much of a difference between the performance of the two forms. However, I always prefer pre-increment since it seems better to directly express what I"m trying to say, rather than relying on the optimizer to figure it out.

Also, giving the optmizer less to do likely means the compiler runs faster.

Roughly you can have 3 choices to display RTSP video stream in a web page:

1. Realplayer
2. Quicktime player
3. VLC player

You can find the code to embed the activeX via google search.

As far as I know, there are some limitations for each player.

1. Realplayer does not support H.264 video natively, you must install a quicktime plugin for Realplayer to achieve H.264 decoding.
2. Quicktime player does not support RTP/AVP/TCP transport, and it's RTP/AVP (UDP) transport does not include NAT hole punching. Thus the only feasible transport is HTTP tunneling in WAN deployment.
3. VLC neither supports NAT hole punching for RTP/AVP transport, but RTP/AVP/TCP transport is available.

I feel the performance characteristics change from one DBMS to another. It's all on how they choose to implement it. Since I have worked extensively on Oracle, I'll tell from that perspective.

COUNT(*) - Fetches entire row into result set before passing on to the count function, count function will aggregate 1 if the row is not null

COUNT(1) - Will not fetch any row, instead count is called with a constant value of 1 for each row in the table when the WHERE matches.

COUNT(PK) - The PK in Oracle is indexed. This means Oracle has to read only the index. Normally one row in the index B+ tree is many times smaller than the actual row. So considering the disk IOPS rate, Oracle can fetch many times more rows from Index with a single block transfer as compared to entire row. This leads to higher throughput of the query.

From this you can see the first count is the slowest and the last count is the fastest in Oracle.

Assuming your string is s:

'$' in s        # found
'$' not in s    # not found

# original answer given, but less Pythonic than the above...
s.find('$')==-1 # not found
s.find('$')!=-1 # found

And so on for other characters.

... or

pattern = re.compile(r'\d\$,')
if pattern.findall(s):
    print('Found')
else
    print('Not found')

... or

chars = set('0123456789$,')
if any((c in chars) for c in s):
    print('Found')
else:
    print('Not Found')

[Edit: added the '$' in s answers]

Update: If you are using Django 1.7+, see the answer below.

Original answer from 2011: You need to create your own admin base_site.html template to do this. The easiest way is to create the file:

/<projectdir>/templates/admin/base_site.html

This should be a copy of the original base_site.html, except putting in your custom title:

{% block branding %}
<h1 id="site-name">{% trans 'my cool admin console' %}</h1>
{% endblock %}

For this to work, you need to have the correct settings for your project, namely in settings.py:

• Make sure /projectdir/templates/ is added into TEMPLATE_DIRS.
• Make sure django.template.loaders.filesystem.Loader is added into TEMPLATE_LOADERS.

See docs for more information on settings.py.

To pass the value you must included the hidden value value="hiddenValue" in the <input> statement like so:

<input type="hidden" id="thisField" name="inputName" value="hiddenValue">

Then you recuperate the hidden form value in the same way that you recuperate the value of visible input fields, by accessing the parameter of the request object. Here is an example:

This code goes on the page where you want to hide the value.

<form action="anotherPage.jsp" method="GET">
    <input type="hidden" id="thisField" name="inputName" value="hiddenValue">
<input type="submit">   
</form>

Then on the 'anotherPage.jsp' page you recuperate the value by calling the getParameter(String name) method of the implicit request object, as so:

<% String hidden = request.getParameter("inputName"); %>
The Hidden Value is <%=hidden %>

The output of the above script will be:

The Hidden Value is hiddenValue 

One (good, IMO) difference between Scala and other languages is that it lets you name your methods with almost any character.

What you enumerate is not "punctuation" but plain and simple methods, and as such their behavior vary from one object to the other (though there are some conventions).

For example, check the Scaladoc documentation for List, and you'll see some of the methods you mentioned here.

Some things to keep in mind:

• Most of the times the A operator+equal B combination translates to A = A operator B, like in the ||= or ++= examples.

• Methods that end in : are right associative, this means that A :: B is actually B.::(A).

You'll find most answers by browsing the Scala documentation. Keeping a reference here would duplicate efforts, and it would fall behind quickly :)

Someone should mark Johannes Weiß's comment as the answer to this question. That is exactly why xml documents can't just be loaded in a DOM Document class.

http://en.wikipedia.org/wiki/Byte_order_mark

use first parameter as your application name. Log.d("your_Application_Name","message");

and in LogCat : create Filter ---> Filter Name & by Log Tag: is equal to 'your_Application_Name' it will create new tab for your application.

From within the class, you can set the (hidden) variable to null. A null reference is the canonical way of representing an empty invocation list, effectively.

From outside the class, you can't do this - events basically expose "subscribe" and "unsubscribe" and that's it.

It's worth being aware of what field-like events are actually doing - they're creating a variable and an event at the same time. Within the class, you end up referencing the variable. From outside, you reference the event.

See my article on events and delegates for more information.

Don't know if this question is relevant anymore, but this happened to me on a client wich had an incorrect datetime set on Windows. This will be an alternative to watch. If is this case, it will reproduce on other browsers as well (at least, on firefox and chrome).

I fixed it updating datetime on Windows to actual's real datetime. Hope it helps somebody.

If none of the other solutions work for you, double check that your scroll view actually is a UIScrollView in Interface Builder.

At some point in the last few days, my UIScrollView spontaneously changed type to a UIView, even though its class said UIScrollView in the inspector. I'm using Xcode 5.1 (5B130a).

You can either create a new scroll view and copy the measurements, settings and constraints from the old view, or you can manually change your view to a UIScrollView in the xib file. I did a compare and found the following differences:

Original:

<scrollView clipsSubviews="YES" multipleTouchEnabled="YES" contentMode="scaleToFill" directionalLockEnabled="YES" bounces="NO" pagingEnabled="YES" showsHorizontalScrollIndicator="NO" showsVerticalScrollIndicator="NO" translatesAutoresizingMaskIntoConstraints="NO" id="Wsk-WB-LMH">
...
</scrollView>

After type spontaneously changed:

<view clearsContextBeforeDrawing="NO" contentMode="scaleToFill" translatesAutoresizingMaskIntoConstraints="NO" customClass="UIScrollView" id="qRn-TP-cXd">
...
</view>

So I replaced the <view> line with my original <scrollView> line.

I also replaced the view's close tag </view> with </scrollView>.

Be sure to keep the id the same as the current view, in this case: id="qRn-TP-cXd".

I also had to flush the xib from Xcode's cache by deleting the app's derived data:

• Xcode->Window->Organizer->Projects, choose your project, on the Derived Data line, click Delete...

Or if using a device:

• Xcode->Window->Organizer->Device, choose your device->Applications, choose your app, click (-)

Now clean the project, and remove the app from the simulator/device:

• Xcode->Product->Clean
• iOS Simulator/device->press and hold the app->click the (X) to remove it

You should then be able to build and run your app and have scrolling functionality again.

P.S. I didn't have to set the scroll view's content size in viewDidLayoutSubviews or turn off auto layout, but YMMV.

Use dojo. No other solution on here is this short or as well-tested:

require(["dojo/io-query"], function(ioQuery){
    var uri = "www.test.com/t.html?a=1&b=3&c=m2-m3-m4-m5 ";
    var query = uri.substring(uri.indexOf("?") + 1, uri.length);
    var queryObject = ioQuery.queryToObject(query);
    console.log(queryObject.c); //prints m2-m3-m4-m5
});

c="123".match(/\D/) == null #true
c="a12".match(/\D/) == null #false

If a string contains only digits it will return null

File 1

class ClassA {

    public $name = 'A';

    public function getName(){
        return $this->name;
    }

}

File 2

include("file1.php");
class ClassB {

    public $name = 'B';

    public function getName(){
        return $this->name;
    }

    public function callA(){
        $a = new ClassA();
        return $a->getName();
    }

    public static function callAStatic(){
        $a = new ClassA();
        return $a->getName();
    }

}

$b = new ClassB();
echo $b->callA();
echo $b->getName();
echo ClassB::callAStatic();

In the following example I'm passing a department parameter to a stored procedure(spIncreaseTotalsRpt) and at the same time I'm creating a temp table all from an OPENQUERY. The Temp table needs to be a global Temp (##) so it can be referenced outside it's intance. By using exec sp_executesql you can pass the department parameter.

Note: be careful when using sp_executeSQL. Also your admin might not have this option available to you.

Hope this helps someone.

 IF OBJECT_ID('tempdb..##Temp') IS NOT NULL
/*Then it exists*/
    begin
       DROP TABLE ##Temp
    end 
 Declare @Dept as nvarchar(20) ='''47'''

 declare @OPENQUERY  as nvarchar(max)
set @OPENQUERY = 'Select ' + @Dept + ' AS Dept,  * into ##Temp from openquery(SQL_AWSPROD01,''' 

declare @sql nvarchar(max)= @openquery +  'SET FMTONLY OFF EXECUTE SalaryCompensation.dbo.spIncreaseTotalsRpts ' + '''' + @Dept + ''''  + ''')'
declare @parmdef nvarchar(25) 
DECLARE @param nvarchar(20) 

SET @parmdef = N'@Dept varchar(20)'
-- select @sql
-- Print @sql + @parmdef  + @dept
exec sp_executesql @sql,@parmdef, @Dept  
Select * from ##Temp

Results

i tried to set default time for a picker and it worked:

$('#date2').datetimepicker({
 format: 'DD-MM-YYYY 12:00:00'
});

this will save in database as : 2015-03-01 12:00:00

used for smalldatetime type in sql server

Use the left function:

QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "

Also have a look at mid() if you want more control.

You can use COALESCE

SELECT COALESCE(SUM(column),0)
FROM   table

Much like leonardocsouza, I had the same problem. To clarify a bit, this is what my folder structure looked like when I ran node server.js

node_modules/
app/
  index.html
  server.js

After printing out the __dirname path, I realized that the __dirname path was where my server was running (app/).

So, the answer to your question is this:

If your server.js file is in the same folder as the files you are trying to render, then

app.use( express.static( path.join( application_root, 'site') ) );

should actually be

app.use(express.static(application_root));

The only time you would want to use the original syntax that you had would be if you had a folder tree like so:

app/
  index.html
node_modules
server.js

where index.html is in the app/ directory, whereas server.js is in the root directory (i.e. the same level as the app/ directory).

Side note: Intead of calling the path utility, you can use the syntax application_root + 'site' to join a path.

Overall, your code could look like:

// Module dependencies.
var application_root = __dirname,
express = require( 'express' ), //Web framework
mongoose = require( 'mongoose' ); //MongoDB integration

//Create server
var app = express();

// Configure server
app.configure( function() {

    //Don't change anything here...

    //Where to serve static content
    app.use( express.static( application_root ) );

    //Nothing changes here either...
});

//Start server --- No changes made here
var port = 5000;
app.listen( port, function() {
    console.log( 'Express server listening on port %d in %s mode', port, app.settings.env );
});

If using tensorflow, there is one_hot():

import tensorflow as tf
import numpy as np

a = np.array([1, 0, 3])
depth = 4
b = tf.one_hot(a, depth)
# <tf.Tensor: shape=(3, 3), dtype=float32, numpy=
# array([[0., 1., 0.],
#        [1., 0., 0.],
#        [0., 0., 0.]], dtype=float32)>

Here's my two cent's worth: I've previously implemented an IdFactory class that created IDs in the format [host name]-[application start time]-[current time]-[discriminator]. This largely guaranteed that IDs were unique across JVM instances whilst keeping the IDs readable (albeit quite long). Here's the code in case it's of any use:

public class IdFactoryImpl implements IdFactory {
  private final String hostName;
  private final long creationTimeMillis;
  private long lastTimeMillis;
  private long discriminator;

  public IdFactoryImpl() throws UnknownHostException {
    this.hostName = InetAddress.getLocalHost().getHostAddress();
    this.creationTimeMillis = System.currentTimeMillis();
    this.lastTimeMillis = creationTimeMillis;
  }

  public synchronized Serializable createId() {
    String id;
    long now = System.currentTimeMillis();

    if (now == lastTimeMillis) {
      ++discriminator;
    } else {
      discriminator = 0;
    }

    // creationTimeMillis used to prevent multiple instances of the JVM
    // running on the same host returning clashing IDs.
    // The only way a clash could occur is if the applications started at
    // exactly the same time.
    id = String.format("%s-%d-%d-%d", hostName, creationTimeMillis, now, discriminator);
    lastTimeMillis = now;

    return id;
  }

  public static void main(String[] args) throws UnknownHostException {
    IdFactory fact = new IdFactoryImpl();

    for (int i=0; i<1000; ++i) {
      System.err.println(fact.createId());
    }
  }
}

This worked for Red Hat Enterprise Linux Server release 6.4

Importing large sql file to MySql via command line

1. first download file .
2. paste file on home.
3. use following command in your terminals(CMD)
4. Syntax: mysql -u username -p databsename < file.sql

Example: mysql -u root -p aanew < aanew.sql

For your case, and 99.9% of all others elclanrs answer is correct.

But because undefined is a valid value, if someone were to test for an uninitialized variable

var pagetype; //== undefined
if (typeof pagetype === 'undefined') //true

the only 100% reliable way to determine if a var exists is to catch the exception;

var exists = false;
try { pagetype; exists = true;} catch(e) {}
if (exists && ...) {}

But I would never write it this way

I had the same issue, but when I ran the following command, it was ok:

php artisan config:cache

You can very easily create an EXE (for Windows) without using any cryptic build commands. You can do it right in Visual Studio.

1. Right click the Console App Project and select Publish.
2. A new page will open up (screen shot below)
3. Hit Configure...
4. Then change Deployment Mode to Self-contained or Framework dependent. .NET Core 3.0 introduces a Single file deployment which is a single executable.
5. Use "framework dependent" if you know the target machine has a .NET Core runtime as it will produce fewer files to install.
6. If you now view the bin folder in explorer, you will find the .exe file.
7. You will have to deploy the exe along with any supporting config and dll files.

It is not python related but for C# or dotnet users you might specify driver version in nuget packages. For instance Selenium.WebDriver.ChromeDriver is a good start point. It should match browser version. In chrome you can check version by accessing

chrome://settings/help

Be informed that it will also affect chrome version on pipeline agents and other developer's computers.

Now you can use either of those options. And it is going to work in any case. Your color can be a HEX code, like this:

myView.setBackgroundResource(ContextCompat.getColor(context, Color.parseColor("#FFFFFF")));

A color resource, like this:

myView.setBackgroundResource(ContextCompat.getColor(context,R.color.blue_background));

Or a custom xml resource, like so:

myView.setBackgroundResource(R.drawable.my_custom_background);

Hope it helps!

Try:

android:layout_height="wrap_content"
android:scaleType="fitStart"

on the image in the RelativeLayout

My problem was that POST requests need trailing slashes '/'.

ArrayList is the collections of different types data whereas List<> is the collection of similar type of its own depedencties.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

You could use SQL.js which is the SQLlite lib compiled to JavaScript and store the database in the local storage introduced in HTML5.

Following up on sas's answer, PHP 5.4, Symfony 2.8, I had to use

ini_set('date.timezone','<whatever timezone string>');

instead of date_default_timezone_set. I also added a call to ini_set to the top of a custom web/config.php to get that check to succeed.

Set the Dropdown arrow image to spinner like this :

<Spinner
    android:id="@+id/Exam_Course"
    android:layout_width="320dp"
    android:background="@drawable/spinner_bg"
    android:layout_height="wrap_content"/>

Here android:background="@drawable/spinner_bg" the spinner_bg is the Dropdown arrow image.

Pandas >= 0.25: Remove Case Distinctions with str.casefold

Starting from v0.25, I recommend using the "vectorized" string method str.casefold if you're dealing with unicode data (it works regardless of string or unicodes):

s = pd.Series(['lower', 'CAPITALS', np.nan, 'SwApCaSe'])
s.str.casefold()

0       lower
1    capitals
2         NaN
3    swapcase
dtype: object

Also see related GitHub issue GH25405.

casefold lends itself to more aggressive case-folding comparison. It also handles NaNs gracefully (just as str.lower does).

But why is this better?

The difference is seen with unicodes. Taking the example in the python str.casefold docs,

Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter 'ß' is equivalent to "ss". Since it is already lowercase, lower() would do nothing to 'ß'; casefold() converts it to "ss".

Compare the output of lower for,

s = pd.Series(["der Fluß"])
s.str.lower()

0    der fluß
dtype: object

Versus casefold,

s.str.casefold()

0    der fluss
dtype: object

Also see Python: lower() vs. casefold() in string matching and converting to lowercase.

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

First, let me explain what a mem-initializer-list is. A mem-initializer-list is a comma-separated list of mem-initializers, where each mem-initializer is a member name followed by (, followed by an expression-list, followed by a ). The expression-list is how the member is constructed. For example, in

static const char s_str[] = "bodacydo";
class Example
{
private:
    int *ptr;
    string name;
    string *pname;
    string &rname;
    const string &crname;
    int age;

public:
    Example()
        : name(s_str, s_str + 8), rname(name), crname(name), age(-4)
    {
    }
};

the mem-initializer-list of the user-supplied, no-arguments constructor is name(s_str, s_str + 8), rname(name), crname(name), age(-4). This mem-initializer-list means that the name member is initialized by the std::string constructor that takes two input iterators, the rname member is initialized with a reference to name, the crname member is initialized with a const-reference to name, and the age member is initialized with the value -4.

Each constructor has its own mem-initializer-list, and members can only be initialized in a prescribed order (basically the order in which the members are declared in the class). Thus, the members of Example can only be initialized in the order: ptr, name, pname, rname, crname, and age.

When you do not specify a mem-initializer of a member, the C++ standard says:

If the entity is a nonstatic data member ... of class type ..., the entity is default-initialized (8.5). ... Otherwise, the entity is not initialized.

Here, because name is a nonstatic data member of class type, it is default-initialized if no initializer for name was specified in the mem-initializer-list. All other members of Example do not have class type, so they are not initialized.

When the standard says that they are not initialized, this means that they can have any value. Thus, because the above code did not initialize pname, it could be anything.

Note that you still have to follow other rules, such as the rule that references must always be initialized. It is a compiler error to not initialize references.

Throwable is super class of Exception as well as Error. In normal cases we should always catch sub-classes of Exception, so that the root cause doesn't get lost.

Only special cases where you see possibility of things going wrong which is not in control of your Java code, you should catch Error or Throwable.

I remember catching Throwable to flag that a native library is not loaded.

This worked in MySQL Workbench 6.0

if you wrote: -Xms512m -Xmx512m when it start, java allocate in those moment 512m of ram for his process and cant increment.

-Xms64m -Xmx512m when it start, java allocate only 64m of ram for his process, but java can be increment his memory occupation while 512m.

I think that second thing is better because you give to java the automatic memory management.

Implementation 1 returns the magnitude of the vector that would result from a regular 3D cross product of the input vectors, taking their Z values implicitly as 0 (i.e. treating the 2D space as a plane in the 3D space). The 3D cross product will be perpendicular to that plane, and thus have 0 X & Y components (thus the scalar returned is the Z value of the 3D cross product vector).

Note that the magnitude of the vector resulting from 3D cross product is also equal to the area of the parallelogram between the two vectors, which gives Implementation 1 another purpose. In addition, this area is signed and can be used to determine whether rotating from V1 to V2 moves in an counter clockwise or clockwise direction. It should also be noted that implementation 1 is the determinant of the 2x2 matrix built from these two vectors.

Implementation 2 returns a vector perpendicular to the input vector still in the same 2D plane. Not a cross product in the classical sense but consistent in the "give me a perpendicular vector" sense.

Note that 3D euclidean space is closed under the cross product operation--that is, a cross product of two 3D vectors returns another 3D vector. Both of the above 2D implementations are inconsistent with that in one way or another.

Hope this helps...

This also seems to work:

while "  " in s:
    s = s.replace("  ", " ")

Where the variable s represents your string.

This is a really annoying one. What I ended up using is this:

First, create a group of simple buttons with no data-toggle attribute.

<div id="selector" class="btn-group">
    <button type="button" class="btn active">Day</button>
    <button type="button" class="btn">Week</button>
    <button type="button" class="btn">Month</button>
    <button type="button" class="btn">Year</button>
</div>

Next, write an event handler that simulates the radio button effect by 'activating' the clicked one and 'deactivating' all other buttons. (EDIT: Integrated Nick's cleaner version from the comments.)

$('#selector button').click(function() {
    $(this).addClass('active').siblings().removeClass('active');

    // TODO: insert whatever you want to do with $(this) here
});

function setDate(){
    var now = new Date();
    now.setMinutes(now.getMinutes() - now.getTimezoneOffset());
    var timeToSet = now.toISOString().slice(0,16);

    /*
        If you have an element called "eventDate" like the following:

        <input type="datetime-local" name="eventdate" id="eventdate" />

        and you would like to  set the current and minimum time then use the following:
    */

    var elem = document.getElementById("eventDate");
    elem.value = timeToSet;
    elem.min = timeToSet;
}

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

Add the following to your AndroidManifest.xml

[ app > src > main > AndroidManifest.xml ]

<activity android:name=".MainActivity"
          android:configChanges="orientation"
          android:screenOrientation="portrait"/>

You can get the source from another domain if you install the ForceCORS filter on Firefox. When you turn on this filter, it will bypass the security feature in the browser and your script will work even if you try to read another webpage. For example, you could open FoxNews.com in an iframe and then read its source. The reason modern web brwosers deny this ability by default is because if the other domain includes a piece of JavaScript and you're reading that and displaying it on your page, it could contain malicious code and pose a security threat. So, whenever you're displaying data from another domain on your page, you must beware of this real threat and implement a way to filter out all JavaScript code from your text before you're going to display it. Remember, when a supposed piece of raw text contains some code enclosed within script tags, they won't show up when you display it on your page, nevertheless they will run! So, realize this is a threat.

Check the Node version you're using, might be a mismatch between what it is expected.

i it integer, int to Integer

Integer intObj = new Integer(i);

add to collection

list.add(String.valueOf(intObj));

Try this function...

function calculate_age(birth_month,birth_day,birth_year)
{
    today_date = new Date();
    today_year = today_date.getFullYear();
    today_month = today_date.getMonth();
    today_day = today_date.getDate();
    age = today_year - birth_year;

    if ( today_month < (birth_month - 1))
    {
        age--;
    }
    if (((birth_month - 1) == today_month) && (today_day < birth_day))
    {
        age--;
    }
    return age;
}

OR

function getAge(dateString) 
{
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) 
    {
        age--;
    }
    return age;
}

See Demo.

You declared them but did not provide them with an intial value - thus, they're unintialized. Try something like:

public static Rand searchCount (int[] x)  
{ 
  int a = 0 ;  
  int b = 0 ; 

and the warnings should go away.

Take for example a game where lots of cars are spawned.. each belongs to the class CCar. When a car is instantiated, it makes a call to

[CCar registerCar:self]

So the CCar class, can make a list of every CCar instantiated. Let's say the user finishes a level, and wants to remove all cars... you could either: 1- Go through a list of every CCar you created manually, and do whicheverCar.remove(); or 2- Add a removeAllCars method to CCar, which will do that for you when you call [CCar removeAllCars]. I.e. allCars[n].remove();

Or for example, you allow the user to specify a default font size for the whole app, which is loaded and saved at startup. Without the class method, you might have to do something like

fontSize = thisMenu.getParent().fontHandler.getDefaultFontSize();

With the class method, you could get away with [FontHandler getDefaultFontSize].

As for your removeVowels function, you'll find that languages like C# actually have both with certain methods such as toLower or toUpper.

e.g. myString.removeVowels() and String.removeVowels(myString) (in ObjC that would be [String removeVowels:myString]).

In this case the instance likely calls the class method, so both are available. i.e.

public function toLower():String{
  return String.toLower();
}

public static function toLower( String inString):String{
 //do stuff to string..
 return newString;
}

basically, myString.toLower() calls [String toLower:ownValue]

There's no definitive answer, but if you feel like shoving a class method in would improve your code, give it a shot, and bear in mind that a class method will only let you use other class methods/variables.

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

Here is pro example of using multi proptypes and single proptype.

import React, { Component } from 'react';
import { string, shape, array, oneOfType } from 'prop-types';

class MyComponent extends Component {
  /**
   * Render
   */
  render() {
    const { title, data } = this.props;

    return (
      <>
        {title}
        <br />
        {data}
      </>
    );
  }
}

/**
 * Define component props
 */
MyComponent.propTypes = {
  data: oneOfType([array, string, shape({})]),
  title: string,
};

export default MyComponent;

In case anyone is setting a ForeignKey, you can just allow nullable fields without setting a default:

new_field = models.ForeignKey(model, null=True)

If you already have data stored within the database, you can also set a default value:

new_field = models.ForeignKey(model, default=<existing model id here>)

To revert modified files:

sudo svn revert
svn status|grep "^ *M" | sed -e 's/^ *M *//'

Aside from limiting the columns selected to reduce bandwidth and memory:

DataTable t;
t.Columns.Remove("columnName");
t.Columns.RemoveAt(columnIndex);

TL;DR

To get the token in a single oneliner:

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | awk '/^deployment-controller-token-/{print $1}') | awk '$1=="token:"{print $2}'

This assumes that your ~/.kube/config is present and valid. And also that kubectl config get-contexts indicates that you are using the correct context (cluster and namespace) for the dashboard you are logging into.

Explanation

I derived this answer from what I learned from @silverfox's answer. That is a very informative write up. Unfortunately it falls short of telling you how to actually put the information into practice. Maybe I've been doing DevOps too long, but I think in shell. It's much more difficult for me to learn or teach in English.

Here is that oneliner with line breaks and indents for readability:

kubectl -n kube-system describe secret $(
  kubectl -n kube-system get secret | \
  awk '/^deployment-controller-token-/{print $1}'
) | \
awk '$1=="token:"{print $2}'

There are 4 distinct commands and they get called in this order:

• Line 2 - This is the first command from @silverfox's Token section.
• Line 3 - Print only the first field of the line beginning with deployment-controller-token- (which is the pod name)
• Line 1 - This is the second command from @silverfox's Token section.
• Line 5 - Print only the second field of the line whose first field is "token:"

I've just stumbled upon this problem too, learning React, and solved it by showing spinner until the data is ready.

    render() {
    if (this.state.data === null) {
        return (
            <div className="MyView">
                <Spinner/>
            </div>
        );
    }
    else {
        return(
            <div className="MyView">
                <ReactJson src={this.state.data}/>
            </div>
        );
    }
}

I would like to slightly rewrite keytarhero's response:

Sub CopyWorkbook()

Dim sh as Worksheet,  wb as workbook

Set wb = workbooks("Target workbook")
For Each sh in workbooks("source workbook").Worksheets
   sh.Copy After:=wb.Sheets(wb.sheets.count) 
Next sh

End Sub

Edit: You can also build an array of sheet names and copy that at once.

Workbooks("source workbook").Worksheets(Array("sheet1","sheet2")).Copy _
         After:=wb.Sheets(wb.sheets.count)

Note: copying a sheet from an XLS? to an XLS will result into an error. The opposite works fine (XLS to XLSX)

Set the DataGridView property

    gridView1.AutoGenerateColumns = true;

And make sure the list of objects your are binding, those object properties should be public.

Made an improvement code by @Ipsita - for use asynchronous read\write file I/O

readonly string logPath = @"FilePath";
...
public async Task WriteToLogAsync(string dataToWrite)
{
    TextReader tr = new StreamReader(logPath);
    string data = await tr.ReadLineAsync();
    tr.Close();

    TextWriter tw = new StreamWriter(logPath);
    await tw.WriteLineAsync(data + dataToWrite);
    tw.Close();
}
...
await WriteToLogAsync("Write this to file");

DECLARE @StartTime datetime
DECLARE @EndTime datetime
SELECT @StartTime=GETDATE() 

 -- Write Your Query


SELECT @EndTime=GETDATE()

--This will return execution time of your query
SELECT DATEDIFF(MS,@StartTime,@EndTime) AS [Duration in millisecs]

Instead of monkey patching or needlessly including large libraries, you can use refinements if you are using Ruby 2:

module HashExtensions
  refine Hash do
    def except!(*candidates)
      candidates.each { |candidate| delete(candidate) }
      self
    end

    def except(*candidates)
      dup.remove!(candidates)
    end
  end
end

You can use this feature without affecting other parts of your program, or having to include large external libraries.

class FabulousCode
  using HashExtensions

  def incredible_stuff
    delightful_hash.except(:not_fabulous_key)
  end
end

The first part:

.Cells(.Rows.Count,"A")

Sends you to the bottom row of column A, which you knew already.

The End function starts at a cell and then, depending on the direction you tell it, goes that direction until it reaches the edge of a group of cells that have text. Meaning, if you have text in cells C4:E4 and you type:

Sheet1.Cells(4,"C").End(xlToRight).Select

The program will select E4, the rightmost cell with text in it.

In your case, the code is spitting out the row of the very last cell with text in it in column A. Does that help?

#header.overlay {
    background-color: SlateGray;
    position:relative;
    width: 100%;
    height: 100%;
    opacity: 0.20;
    -moz-opacity: 20%;
    -webkit-opacity: 20%;
    z-index: 2;
}

Something like this. Just add the overlay class to the header, obviously.

I always use this.It send form data using ajax

$(document).on("submit", "form", function(event)
{
    event.preventDefault();

    var url=$(this).attr("action");
    $.ajax({
        url: url,
        type: 'POST',            
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        }
    });
});

This:

var foo = new Foo();

and

var foo = Object.create(Foo.prototype);

are quite similar. One important difference is that new Foo actually runs constructor code, whereas Object.create will not execute code such as

function Foo() {
    alert("This constructor does not run with Object.create");
}

Note that if you use the two-parameter version of Object.create() then you can do much more powerful things.

In ASP.NET, when should I use Session.Clear() rather than Session.Abandon()?

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

What is the difference between Session.Abandon() and Session.Clear()

Clear - Removes all keys and values from the session-state collection.

Abandon - removes all the objects stored in a Session. If you do not call the Abandon method explicitly, the server removes these objects and destroys the session when the session times out. It also raises events like Session_End.

Session.Clear can be compared to removing all books from the shelf, while Session.Abandon is more like throwing away the whole shelf.

...

Generally, in most cases you need to use Session.Clear. You can use Session.Abandon if you are sure the user is going to leave your site.

So back to the differences:

• Abandon raises Session_End request.
• Clear removes items immediately, Abandon does not.
• Abandon releases the SessionState object and its items so it can garbage collected.
• Clear keeps SessionState and resources associated with it.

Session.Clear() or Session.Abandon() ?

You use Session.Clear() when you don't want to end the session but rather just clear all the keys in the session and reinitialize the session.

Session.Clear() will not cause the Session_End eventhandler in your Global.asax file to execute.

But on the other hand Session.Abandon() will remove the session altogether and will execute Session_End eventhandler.

Session.Clear() is like removing books from the bookshelf

Session.Abandon() is like throwing the bookshelf itself.

Question

I check on some sessions if not equal null in the page load. if one of them equal null i wanna to clear all the sessions and redirect to the login page?

Answer

If you want the user to login again, use Session.Abandon.

This works if you want to make generating files look cool .

                int num = 1;
                var spin = new ConsoleSpinner();
                Console.ForegroundColor = ConsoleColor.Green;
                Console.Write("");
                while (true)
                {
                    spin.Turn();
                    Console.Write("\r{0} Generating Files ", num);
                    num++;
                }

And this is the method that i got from some answer below and modified it

public class ConsoleSpinner
    {
        int counter;

        public void Turn()
        {
            counter++;
            switch (counter % 4)
            {
                case 0: Console.Write("."); counter = 0; break;
                case 1: Console.Write(".."); break;
                case 2: Console.Write("..."); break;
                case 3: Console.Write("...."); break;
                case 4: Console.Write("\r"); break;
            }
            Thread.Sleep(100);
            Console.SetCursorPosition(23, Console.CursorTop);
        }
    }

I'm developing an app that needs to look similar in all devices with >= API14 when it comes to actionbar and statusbar customization. I've finally found a solution and since it took a bit of my time I'll share it to save some of yours. We start by using an appcompat-21 dependency.

Transparent Actionbar:

values/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light">
...
</style>

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="android:windowContentOverlay">@null</item>
    <item name="windowActionBarOverlay">true</item>
    <item name="colorPrimary">@android:color/transparent</item>
</style>

<style name="AppTheme.ActionBar" parent="AppTheme">
    <item name="windowActionBarOverlay">false</item>
    <item name="colorPrimary">@color/default_yellow</item>
</style>

values-v21/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    ...
</style>

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="colorPrimary">@android:color/transparent</item>
</style>

<style name="AppTheme.ActionBar" parent="AppTheme">
    <item name="colorPrimaryDark">@color/bg_colorPrimaryDark</item>
    <item name="colorPrimary">@color/default_yellow</item>
</style>

Now you can use these themes in your AndroidManifest.xml to specify which activities will have a transparent or colored ActionBar:

    <activity
            android:name=".MyTransparentActionbarActivity"
            android:theme="@style/AppTheme.ActionBar.Transparent"/>

    <activity
            android:name=".MyColoredActionbarActivity"
            android:theme="@style/AppTheme.ActionBar"/>

Note: in API>=21 to get the Actionbar transparent you need to get the Statusbar transparent too, otherwise will not respect your colour styles and will stay light-grey.

Transparent Statusbar (only works with API>=19):
This one it's pretty simple just use the following code:

protected void setStatusBarTranslucent(boolean makeTranslucent) {
        if (makeTranslucent) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        } else {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

But you'll notice a funky result:

This happens because when the Statusbar is transparent the layout will use its height. To prevent this we just need to:

SOLUTION ONE:
Add this line android:fitsSystemWindows="true" in your layout view container of whatever you want to be placed bellow the Actionbar:

    ...
        <LinearLayout
                android:fitsSystemWindows="true"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
            ...
        </LinearLayout>
    ...

SOLUTION TWO:
Add a few lines to our previous method:

protected void setStatusBarTranslucent(boolean makeTranslucent) {
        View v = findViewById(R.id.bellow_actionbar);
        if (v != null) {
            int paddingTop = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT ? MyScreenUtils.getStatusBarHeight(this) : 0;
            TypedValue tv = new TypedValue();
            getTheme().resolveAttribute(android.support.v7.appcompat.R.attr.actionBarSize, tv, true);
            paddingTop += TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
            v.setPadding(0, makeTranslucent ? paddingTop : 0, 0, 0);
        }

        if (makeTranslucent) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        } else {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

Where R.id.bellow_actionbar will be the layout container view id of whatever we want to be placed bellow the Actionbar:

...
    <LinearLayout
            android:id="@+id/bellow_actionbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        ...
    </LinearLayout>
...

So this is it, it think I'm not forgetting something. In this example I didn't use a Toolbar but I think it'll have the same result. This is how I customize my Actionbar:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        View vg = getActionBarView();
        getWindow().requestFeature(vg != null ? Window.FEATURE_ACTION_BAR : Window.FEATURE_NO_TITLE);

        super.onCreate(savedInstanceState);
        setContentView(getContentView());

        if (vg != null) {
            getSupportActionBar().setCustomView(vg, new ActionBar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

            getSupportActionBar().setDisplayUseLogoEnabled(false);
        }
        setStatusBarTranslucent(true);
    }

Note: this is an abstract class that extends ActionBarActivity
Hope it helps!

You can also use this trick: replace

$("#topbar").click(function(){

by

$(document).on("click", "#topbar", function(){

This will bind an event on a not loaded yet object... ;)

int dp1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 1,
            context.getResources().getDisplayMetrics());

tv.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
dp1 * 100)); // if you want to set layout height to 100dp

llview.addView(tv);

I checked many solutions and anyone wasn't working good.

So I tried a small trick and it works:

tfoot with style:position: fixed; bottom: 0px; is placed at the bottom of last page, but if footer is too high it is overlapped by content of table.

tfoot with only: display: table-footer-group; isn't overlapped, but is not on the bottom of last page...

Let's put two tfoot:

TFOOT.placer {_x000D_
  display: table-footer-group;_x000D_
  height: 130px;_x000D_
}_x000D_
_x000D_
TFOOT.contenter {_x000D_
  display: table-footer-group;_x000D_
  position: fixed;_x000D_
  bottom: 0px; _x000D_
  height: 130px;_x000D_
}

<TFOOT  class='placer'> _x000D_
  <TR>_x000D_
    <TD>_x000D_
      <!--  empty here_x000D_
-->_x000D_
    </TD>_x000D_
  </TR>_x000D_
</TFOOT> _x000D_
<TFOOT  class='contenter'> _x000D_
  <TR>_x000D_
    <TD>_x000D_
      your long text or high image here_x000D_
    </TD>_x000D_
  </TR>_x000D_
</TFOOT>

One reserves place on non-last pages, second puts in your accual footer.

If you're having problems with phpize not found on CentOS7.x after you have installed the relevant devel tools for your version/s of PHP, this path finally worked for me:

For PHP 7.2.x

/opt/cpanel/ea-php72/root/usr/bin/phpize

For PHP 7.3.x

/opt/cpanel/ea-php73/root/usr/bin/phpize

For PHP 7.4.x

/opt/cpanel/ea-php74/root/usr/bin/phpize

Run this in your folder containing the downloaded PHP extension, for example in line 3 below:

Example based on installing the PHP v7.3.x Brotli Extension from https://github.com/kjdev/php-ext-brotli

git clone --recursive --depth=1 https://github.com/kjdev/php-ext-brotli.git
cd /php-ext-brotli
/opt/cpanel/ea-php73/root/usr/bin/phpize
./configure --with-php-config=/opt/cpanel/ea-php73/root/usr/bin/php-config
make
make test

I have written on this property framework for the last year. It will provide of multiple ways to load properties, and have them strongly typed as well.

Have a look at http://sourceforge.net/projects/jhpropertiestyp/

JHPropertiesTyped will give the developer strongly typed properties. Easy to integrate in existing projects. Handled by a large series for property types. Gives the ability to one-line initialize properties via property IO implementations. Gives the developer the ability to create own property types and property io's. Web demo is also available, screenshots shown above. Also have a standard implementation for a web front end to manage properties, if you choose to use it.

Complete documentation, tutorial, javadoc, faq etc is a available on the project webpage.

lst *= 0

has the same effect as

lst[:] = []

It's a little simpler and maybe easier to remember. Other than that there's not much to say

The efficiency seems to be about the same

I wrote rather good function that can generate vertical and horizontal tables:

function generateTable(rowsData, titles, type, _class) {
    var $table = $("<table>").addClass(_class);
    var $tbody = $("<tbody>").appendTo($table);


    if (type == 2) {//vertical table
        if (rowsData.length !== titles.length) {
            console.error('rows and data rows count doesent match');
            return false;
        }
        titles.forEach(function (title, index) {
            var $tr = $("<tr>");
            $("<th>").html(title).appendTo($tr);
            var rows = rowsData[index];
            rows.forEach(function (html) {
                $("<td>").html(html).appendTo($tr);
            });
            $tr.appendTo($tbody);
        });

    } else if (type == 1) {//horsantal table 
        var valid = true;
        rowsData.forEach(function (row) {
            if (!row) {
                valid = false;
                return;
            }

            if (row.length !== titles.length) {
                valid = false;
                return;
            }
        });

        if (!valid) {
            console.error('rows and data rows count doesent match');
            return false;
        }

        var $tr = $("<tr>");
        titles.forEach(function (title, index) {
            $("<th>").html(title).appendTo($tr);
        });
        $tr.appendTo($tbody);

        rowsData.forEach(function (row, index) {
            var $tr = $("<tr>");
            row.forEach(function (html) {
                $("<td>").html(html).appendTo($tr);
            });
            $tr.appendTo($tbody);
        });
    }

    return $table;
}

usage example:

var title = [
    '????? ?????',
    '????? ?????????',
    '????? ?? ???'
];

var rows = [
    [number_format(data.source.area,2)],
    [number_format(data.intersection.area,2)],
    [number_format(data.deference.area,2)]
];

var $ft = generateTable(rows, title, 2,"table table-striped table-hover table-bordered");

$ft.appendTo( GroupAnalyse.$results );

var title = [
    '???',
    '?????? ????',
    '?????? ????',
    '?????',
    '????? ??? ?????',
];

var rows = data.edgesData.map(function (r) {
    return [
        r.directionText,
        r.lineLength,
        r.newLineLength,
        r.stateText,
        r.lineLengthDifference
    ];
});


var $et = generateTable(rows, title, 1,"table table-striped table-hover table-bordered");

$et.appendTo( GroupAnalyse.$results );

$('<hr/>').appendTo( GroupAnalyse.$results );

example result:

Yes, you must have to open php.ini and remove the semicolon to:

;extension=php_openssl.dll

remove the ";" like this and it will work.

extension=php_openssl.dll

Happy Coding.

TextPad will allow you to perform this operation.

example:

test this sentence

Find what: \([^ ]*\) \(.*\) Replace with: \U\1\E \2

the \U will cause all following chars to be upper

the \E will turn off the \U

the result will be:

TEST this sentence

The angular.forEach() will iterate through your json object.

First iteration,

key = 0, value = { "name" : "Thomas", "password" : "thomasTheKing"}

Second iteration,

key = 1, value = { "name" : "Linda", "password" : "lindatheQueen" }

To get the value of your name, you can use value.name or value["name"]. Same with your password, you use value.password or value["password"].

The code below will give you what you want:

   angular.forEach(json, function (value, key)
         {
                //console.log(key);
                //console.log(value);
                if (value.password == "thomasTheKing") {
                    console.log("username is thomas");
                }
         });

A compiler consists of two major blocks: the 'front end' and the 'back end'. The front end of a compiler analyzes the source code and builds some form of a 'intermediary representation' of said source code which is much easier to analyze by a machine algorithm than is the source code (i.e. whereas the source code e.g. C++ is designed to help the human programmer to write code, the intermediary form is designed to help simplify the algorithm that analyzes said intermediary form easier). The back end of a compiler takes the intermediary form and then converts it to a 'target language'.

Now, the target language for general-use compilers are assembler languages for various processors, but there's nothing to prohibit a compiler back end to produce code in some other language, for as long as said target language is (at least) as flexible as a general CPU assembler.

Now, as you can probably imagine, C is definitely as flexible as a CPU's assembler, such that a C++ to C compiler is really no problem to implement from a technical pov.

So you have: C++ ---frontEnd---> someIntermediaryForm ---backEnd---> C

You may want to check these guys out: http://www.edg.com/index.php?location=c_frontend (the above link is just informative for what can be done, they license their front ends for tens of thousands of dollars)

PS As far as i know, there is no such a C++ to C compiler by GNU, and this totally beats me (if i'm right about this). Because the C language is fairly small and it's internal mechanisms are fairly rudimentary, a C compiler requires something like one man-year work (i can tell you this first hand cause i wrote such a compiler myself may years ago, and it produces a [virtual] stack machine intermediary code), and being able to have a maintained, up-to-date C++ compiler while only having to write a C compiler once would be a great thing to have...

One line of code:

get-package *notepad* |% { & $_.Meta.Attributes["UninstallString"]}

Actually, You can achieve this with current typescript:

type Grow<T, A extends Array<T>> = ((x: T, ...xs: A) => void) extends ((...a: infer X) => void) ? X : never;
type GrowToSize<T, A extends Array<T>, N extends number> = { 0: A, 1: GrowToSize<T, Grow<T, A>, N> }[A['length'] extends N ? 0 : 1];

export type FixedArray<T, N extends number> = GrowToSize<T, [], N>;

Examples:

// OK
const fixedArr3: FixedArray<string, 3> = ['a', 'b', 'c'];

// Error:
// Type '[string, string, string]' is not assignable to type '[string, string]'.
//   Types of property 'length' are incompatible.
//     Type '3' is not assignable to type '2'.ts(2322)
const fixedArr2: FixedArray<string, 2> = ['a', 'b', 'c'];

// Error:
// Property '3' is missing in type '[string, string, string]' but required in type 
// '[string, string, string, string]'.ts(2741)
const fixedArr4: FixedArray<string, 4> = ['a', 'b', 'c'];

EDIT (after a long time)

This should handle bigger sizes (as basically it grows array exponentially until we get to closest power of two):

type Shift<A extends Array<any>> = ((...args: A) => void) extends ((...args: [A[0], ...infer R]) => void) ? R : never;

type GrowExpRev<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExpRev<[...A, ...P[0]], N, P>,
  1: GrowExpRev<A, N, Shift<P>>
}[[...A, ...P[0]][N] extends undefined ? 0 : 1];

type GrowExp<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExp<[...A, ...A], N, [A, ...P]>,
  1: GrowExpRev<A, N, P>
}[[...A, ...A][N] extends undefined ? 0 : 1];

export type FixedSizeArray<T, N extends number> = N extends 0 ? [] : N extends 1 ? [T] : GrowExp<[T, T], N, [[T]]>;

I think that parse_str is what you're looking for, something like this should do the trick for you:

parse_str($_SERVER['QUERY_STRING'], $vars);

Then the $vars array will hold all the passed arguments.

I had a similar error. The problem had to do with the child and parent table not having the same charset and collation. This can be fixed by appending ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;

CREATE TABLE IF NOT EXISTS `country` (`id` INT(11) NOT NULL AUTO_INCREMENT,...) ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;

... on the SQL statement means that there is some missing code.

As mentioned in comments, this is a scoping issue. Specifically, $con is not in scope within your getPosts function.

You should pass your connection object in as a dependency, eg

function getPosts(mysqli $con) {
    // etc

I would also highly recommend halting execution if your connection fails or if errors occur. Something like this should suffice

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); // throw exceptions
$con=mysqli_connect("localhost","xxxx","xxxx","xxxxx");

getPosts($con);

No.

Calling document.getElementById('id') will return a raw DOM object.

Calling $('#id') will return a jQuery object that wraps the DOM object and provides jQuery methods.

Thus, you can only call jQuery methods like css() or animate() on the $() call.

You can also write $(document.getElementById('id')), which will return a jQuery object and is equivalent to $('#id').

You can get the underlying DOM object from a jQuery object by writing $('#id')[0].

Fix for this issue is simple :

• Go to SDK tools > SDK Tools
• Check Android Emulator and click Apply

and sometimes you might see there's an update available next to it, you just need to let it finish the update

Here is the simplest way:

Guid guid = Guid.NewGuid();
Random random = new Random();
int i = random.Next();

You'll notice that guid is not actually used here, mainly because there would be no point in using it. Microsoft's GUID algorithm does not use the computer's MAC address any more - GUID's are actually generated using a pseudo-random generator (based on time values), so if you want a random integer it makes more sense to use the Random class for this.

Update: actually, using a GUID to generate an int would probably be worse than just using Random ("worse" in the sense that this would be more likely to generate collisions). This is because not all 128 bits in a GUID are random. Ideally, you would want to exclude the non-varying bits from a hashing function, although it would be a lot easier to just generate a random number, as I think I mentioned before. :)

An alternative way without the [<- function:

A sample data frame dat (shamelessly copied from @Chase's answer):

dat

  x y
1 0 2
2 1 2
3 1 1
4 2 1
5 0 0

Zeroes can be replaced with NA by the is.na<- function:

is.na(dat) <- !dat


dat

   x  y
1 NA  2
2  1  2
3  1  1
4  2  1
5 NA NA

Use the eq selector to selct the nth row (0-based) and add your row after it using after, so:

$('#my_table > tbody:last tr:eq(2)').after(html);

where html is a tr

If the list contains unhashable items, you can use Alex Martelli's solution but with a list instead of a set, though it's slower for larger inputs: O(N^2).

def has_duplicates(iterable):
    seen = []
    for x in iterable:
        if x in seen:
            return True
        seen.append(x)
    return False

To replace anything that starts with "text" until the last character:

text.+(.*)$

Example

text             hsjh sdjh sd          jhsjhsdjhsdj hsd
                                                      ^
                                                      last character

text.+(\ 123)

Example

text fuhfh283nfnd03no3 d90d3nd 3d 123 udauhdah au dauh ej2e

You can provide password as parameter to expect script.

Today, in the year 2016, it is save to use document.querySelector without knowing the ID (especially if you have more than 2 radio buttons):

document.querySelector("input[name=main-categories]:checked").value

this can be done with os.walk()

python 3.5.2 tested;

import os
for root, dirs, files in os.walk('.', topdown=True):
    dirs.clear() #with topdown true, this will prevent walk from going into subs
    for file in files:
      #do some stuff
      print(file)

remove the dirs.clear() line and the files in sub folders are included again.

update with references;

os.walk documented here and talks about the triple list being created and topdown effects.

.clear() documented here for emptying a list

so by clearing the relevant list from os.walk you can effect its result to your needs.

There are a thousand and one ways to do it. Here's one using dc (a reverse-polish desk calculator which supports unlimited precision arithmetic):

dc <<<"$num1 $num2 + p"

But if that's too bash-y for you (or portability matters) you could say

echo $num1 $num2 + p | dc

But maybe you're one of those people who thinks RPN is icky and weird; don't worry! bc is here for you:

bc <<< "$num1 + $num2"
echo $num1 + $num2 | bc

That said, there are some unrelated improvements you could be making to your script:

#!/bin/bash

num=0
metab=0

for ((i=1; i<=2; i++)); do
    for j in output-$i-* ; do # 'for' can glob directly, no need to ls
            echo "$j"

             # 'grep' can read files, no need to use 'cat'
            metab=$(grep EndBuffer "$j" | awk '{sum+=$2} END { print sum/120}')
            num=$(( $num + $metab ))
    done
    echo "$num"
done

As described in Bash FAQ 022, Bash does not natively support floating point numbers. If you need to sum floating point numbers the use of an external tool (like bc or dc) is required.

In this case the solution would be

num=$(dc <<<"$num $metab + p")

To add accumulate possibly-floating-point numbers into num.

Alternatively, if you're just looking to play around with Javascript a nice in browser option is Codecademy's Javascript Lab.

They also have a Python and Ruby IDE.

Your route isn't ok, it should be like this (with ':')

app.get('/documents/:format/:type', function (req, res) {
   var format = req.params.format,
       type = req.params.type;
});

Also you cannot interchange parameter order unfortunately. For more information on req.params (and req.query) check out the api reference here.

You can use DSUM, which will be more flexible. Like if you want to change the name of Salesman or the Quote Month, you need not change the formula, but only some criteria cells. Please see the link below for details...Even the criteria can be formula to copied from other sheets

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

One main difference is that || and && exhibit "short-circuiting", so the RHS will only be evaluated if needed.

For e.g.

if (a || b) {
    path1...
} else {
    path2..
}

Above if a is true then b will not be tested and path1 is executed. If | was used then both sides would be evaluated even if 'a' is true.

See Here and here, for a little more information.

Hope this helps.

If you prefer to use a library, use ts-essentials.

import { Omit } from "ts-essentials";

type ComplexObject = {
  simple: number;
  nested: {
    a: string;
    array: [{ bar: number }];
  };
};

type SimplifiedComplexObject = Omit<ComplexObject, "nested">;

// Result:
// {
//  simple: number
// }

// if you want to Omit multiple properties just use union type:
type SimplifiedComplexObject = Omit<ComplexObject, "nested" | "simple">;

// Result:
// { } (empty type)

PS: You will find lots of other useful stuff there ;)

Try with this code line:

Collections.singletonList(provider)

You could process the file while being read by using streams. It's just like using buffers but with a more convenient API.

var fs = require('fs');
function searchReplaceFile(regexpFind, replace, cssFileName) {
    var file = fs.createReadStream(cssFileName, 'utf8');
    var newCss = '';

    file.on('data', function (chunk) {
        newCss += chunk.toString().replace(regexpFind, replace);
    });

    file.on('end', function () {
        fs.writeFile(cssFileName, newCss, function(err) {
            if (err) {
                return console.log(err);
            } else {
                console.log('Updated!');
            }
    });
});

searchReplaceFile(/foo/g, 'bar', 'file.txt');

You cannot resize an array in java.

Once the size of array is declared, it remains fixed.

Instead you can use ArrayList that has dynamic size, meaning you don't need to worry about its size. If your array list is not big enough to accommodate new values then it will be resized automatically.

ArrayList<String> ar = new ArrayList<String>();
String s1 ="Test1";
String s2 ="Test2";
String s3 ="Test3";
ar.add(s1);
ar.add(s2);
ar.add(s3);

String s4 ="Test4";
ar.add(s4);

If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest

android:exported="true"

Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.

finish();

The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class in the code, so compile will fail.

I searched on the web and found something like this below, and it works well.

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);

You can also use the setClassName method:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();

You can also pass the values from one app to another app :

Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
    launchIntent.putExtra("AppID", "MY-CHILD-APP1");
    launchIntent.putExtra("UserID", "MY-APP");

The usual solution is to create a class which manages the access to this environmental variable, which you can then mock in your test class.

public class Environment {
    public String getVariable() {
        return System.getenv(); // or whatever
    }
}

public class ServiceTest {
    private static class MockEnvironment {
        public String getVariable() {
           return "foobar";
        }
    }

    @Test public void testService() {
        service.doSomething(new MockEnvironment());
    }
}

The class under test then gets the environment variable using the Environment class, not directly from System.getenv().

If you want to avoid the error message and you are not using Bootstrap tool tips, you can define window.Tether before loading Bootstrap.

<script>
  window.Tether = {};
</script>
<script src="js/bootstrap.min.js"></script>

For Linux you click on the three dots "..." beside the emulator, on Virtual sensors check "Move" and then try quickly moving either x, y or z coordinates.

Here you go, Python documentation on old string formatting. tutorial -> 7.1.1. Old String Formatting -> "More information can be found in the [link] section".

Note that you should start using the new string formatting when possible.

Window ? Preferences ? General ? Network Connections then under "Proxy ByPass" click "Add Host" and enter the link from which you will be getting your third-party plugin; that's it bingo, now it should get the plugin no problem.

driver.findElement(By.id("invoice_supplier_id")).setAttribute("value", "your value");

@chapinkapa's answer is good. An approach that I have taken since Mobile Center does not support environment variables, is to expose build configuration through a native module:

On android:

   @Override
    public Map<String, Object> getConstants() {
        final Map<String, Object> constants = new HashMap<>();
        String buildConfig = BuildConfig.BUILD_TYPE.toLowerCase();
        constants.put("ENVIRONMENT", buildConfig);
        return constants;
    } 

or on ios:

  override func constantsToExport() -> [String: Any]! {
    // debug/ staging / release
    // on android, I can tell the build config used, but here I use bundle name
    let STAGING = "staging"
    let DEBUG = "debug"

    var environment = "release"
    if let bundleIdentifier: String = Bundle.main.bundleIdentifier {
      if (bundleIdentifier.lowercased().hasSuffix(STAGING)) {
        environment = STAGING
      } else if (bundleIdentifier.lowercased().hasSuffix(DEBUG)){
        environment = DEBUG
      }
    }

    return ["ENVIRONMENT": environment]
  }

You can read the build config synchronously and decide in Javascript how you're going to behave.

The TRUNCATE statement was my first problem, glad to find the solution here. But I was using SSIS and trying to load data from another database, and it failed with the same error on any table that used IDENTITY to create an auto-incrementing ID. If I was scripting it myself I'd first need to use the command SET IDENTITY_INSERT tablename ON, and then SET IDENTITY_INSERT tablename OFF when the table update was done. But this requires ALTER permissions on the table, which I do not have. Hence the error message in SSIS on the table load (even though the previous step had just deleted all the data out of the table.)

Prepending a BOM (\uFEFF) worked for me (Excel 2007), in that Excel recognised the file as UTF-8. Otherwise, saving it and using the import wizard works, but is less ideal.

In my case the "SQL Server" Server service stopped. When I restarted the service that enabled me to run the query and eliminate the error.

Its also a good idea to examine your query to find out why the query made this service stop

The requests.Session() solution assisted with logging into a form with CSRF Protection (as used in Flask-WTF forms). Check if a csrf_token is required as a hidden field and add it to the payload with the username and password:

import requests
from bs4 import BeautifulSoup

payload = {
    'email': '[email protected]',
    'password': 'passw0rd'
}     

with requests.Session() as sess:
    res = sess.get(server_name + '/signin')
    signin = BeautifulSoup(res._content, 'html.parser')
    payload['csrf_token'] = signin.find('input', id='csrf_token')['value']
    res = sess.post(server_name + '/auth/login', data=payload)

Simply putting - this.setState({data: value}) is asynchronous in nature that means it moves out of the Call Stack and only comes back to the Call Stack unless it is resolved.

Please read about Event Loop to have a clear picture about Asynchronous nature in JS and why it takes time to update -

https://medium.com/front-end-weekly/javascript-event-loop-explained-4cd26af121d4

Hence -

    this.setState({data:value});
    console.log(this.state.data); // will give undefined or unupdated value

as it takes time to update. To achieve the above process -

    this.setState({data:value},function () {
     console.log(this.state.data);
    });

One place where I use @import is when I'm doing two versions of a page, English and French. I'll build out my page in English, using a main.css. When I build out the French version, I'll link to a French stylesheet (main_fr.css). At the top of the French stylesheet, I'll import the main.css, and then redefine specific rules for just the parts I need different in the French version.

To exclude dotfiles in base directory:

scp -r [!.]* server:/path/to/something

[!.]* is a shell glob that expands to all files in working directory not starting with a dot.

It is usually a good idea to declare variables as unsigned or size_t if they will be compared to sizes, to avoid this issue. Whenever possible, use the exact type you will be comparing against (for example, use std::string::size_type when comparing with a std::string's length).

Compilers give warnings about comparing signed and unsigned types because the ranges of signed and unsigned ints are different, and when they are compared to one another, the results can be surprising. If you have to make such a comparison, you should explicitly convert one of the values to a type compatible with the other, perhaps after checking to ensure that the conversion is valid. For example:

unsigned u = GetSomeUnsignedValue();
int i = GetSomeSignedValue();

if (i >= 0)
{
    // i is nonnegative, so it is safe to cast to unsigned value
    if ((unsigned)i >= u)
        iIsGreaterThanOrEqualToU();
    else
        iIsLessThanU();
}
else
{
    iIsNegative();
}

I finally found a solution on Windows, to have a real silent and automatic install:

On Windows, the following syntax doesn't work:

echo y | sdkmanager --licenses

It seems the "y" aren't correctly sent to the java program called in the batch.

The workaround is to create a file file-y.txt with several "y", one by line, and to use

call sdkmanager --licenses < file-y.txt

This will create the needed files in the licenses directory. The problem is probably related to the use of BufferedReader in Java

Put the varible in an array and Use a for Loop to assign the same value to multiple variables.

  myArray[moveUP, moveDown, moveLeft];

    for(var i = 0; i < myArray.length; i++){

        myArray[i] = true;

    }

To do that you should do:

a =  [5, 7, 11, 4, 5]
for i in range(len(a)-1):
    print [a[i], a[i+1]]

Short answer: minimum possible access (cf Jon Skeet's answer).

Long answer:

Non-nested types, enumeration and delegate accessibilities (may only have internal or public accessibility)

                     | Default   | Permitted declared accessibilities
------------------------------------------------------------------
namespace            | public    | none (always implicitly public)

enum                 | public    | public, internal

interface            | internal  | public, internal

class                | internal  | public, internal

struct               | internal  | public, internal

delegate             | internal  | public, internal

Nested type and member accessiblities

                     | Default   | Permitted declared accessibilities
------------------------------------------------------------------
namespace            | public    | none (always implicitly public)

enum                 | public    | All¹

interface            | public    | All¹

class                | private   | All¹

struct               | private   | public, internal, private²

delegate             | private   | All¹

constructor          | private   | All¹

enum member          | public    | none (always implicitly public)

interface member     | public    | none (always implicitly public)
     
method               | private   | All¹

field                | private   | All¹

user-defined operator| none      | public (must be declared public)

¹ All === public, protected, internal, private, protected internal

² structs cannot inherit from structs or classes (although they can, interfaces), hence protected is not a valid modifier

The accessibility of a nested type depends on its accessibility domain, which is determined by both the declared accessibility of the member and the accessibility domain of the immediately containing type. However, the accessibility domain of a nested type cannot exceed that of the containing type.

Note: CIL also has the provision for protected and internal (as opposed to the existing protected "or" internal), but to my knowledge this is not currently available for use in C#.

use this.animationStop, not use this.animationStop ( )

animationRun(){
    this.sliderClass.anim = true;
    setTimeout(this.animationStop, 500);
},

You can use reduce() without any regex:

(str, n) => {
  return str.split('').reduce(
    (acc, rec, index) => {
      return ((index % n) || !(index)) ? acc.concat(rec) : acc.concat(',', rec)
    },
    ''
  ).split(',')
}

Go to settings in Chrome and then to Advanced settings, under privacy and security section click Clear browsing data and then clear all data. I followed these steps and it worked for me. Hope it helps some one.

Check my code that will work for integer and String.

Assume our first number is 129018. And we want to add zeros to that so the the length of final string will be 10. For that you can use following code

    int number=129018;
    int requiredLengthAfterPadding=10;
    String resultString=Integer.toString(number);
    int inputStringLengh=resultString.length();
    int diff=requiredLengthAfterPadding-inputStringLengh;
    if(inputStringLengh<requiredLengthAfterPadding)
    {
        resultString=new String(new char[diff]).replace("\0", "0")+number;
    }        
    System.out.println(resultString);

This seems to be a little buggy in Pandas 0.23.4?

If there are np.nan values then this will throw an error as expected:

df['col'] = df['col'].astype(np.int64)

But doesn't change any values from float to int as I would expect if "ignore" is used:

df['col'] = df['col'].astype(np.int64,errors='ignore') 

It worked if I first converted np.nan:

df['col'] = df['col'].fillna(0).astype(np.int64)
df['col'] = df['col'].astype(np.int64)

Now I can't figure out how to get null values back in place of the zeroes since this will convert everything back to float again:

df['col']  = df['col'].replace(0,np.nan)

This has been discussed in many posts but still I could not figure out a solution with:

android:focusable="false"
android:focusableInTouchMode="false"
android:focusableInTouchMode="false"

Below solution will work with any of the ui components : Button, ImageButtons, ImageView, Textview. LinearLayout, RelativeLayout clicks inside a listview cell and also will respond to onItemClick:

Adapter class - getview():

    @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view = convertView;
            if (view == null) {
                view = lInflater.inflate(R.layout.my_ref_row, parent, false);
            }
            final Organization currentOrg = organizationlist.get(position).getOrganization();

            TextView name = (TextView) view.findViewById(R.id.name);
            Button btn = (Button) view.findViewById(R.id.btn_check);
            btn.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    context.doSelection(currentOrg);

                }
            });

       if(currentOrg.isSelected()){
            btn.setBackgroundResource(R.drawable.sub_search_tick);
        }else{
            btn.setBackgroundResource(R.drawable.sub_search_tick_box);
        }

    }

In this was you can get the button clicked object to the activity. (Specially when you want the button to act as a check box with selected and non-selected states):

    public void doSelection(Organization currentOrg) {
        Log.e("Btn clicked ", currentOrg.getOrgName());
        if (currentOrg.isSelected() == false) {
            currentOrg.setSelected(true);
        } else {
            currentOrg.setSelected(false);
        }
        adapter.notifyDataSetChanged();

    }

Filter array of objects, which property matches value, returns array:

var result = jsObjects.filter(obj => {
  return obj.b === 6
})

See the MDN Docs on Array.prototype.filter()

const jsObjects = [_x000D_
  {a: 1, b: 2}, _x000D_
  {a: 3, b: 4}, _x000D_
  {a: 5, b: 6}, _x000D_
  {a: 7, b: 8}_x000D_
]_x000D_
_x000D_
let result = jsObjects.filter(obj => {_x000D_
  return obj.b === 6_x000D_
})_x000D_
_x000D_
console.log(result)

Find the value of the first element/object in the array, otherwise undefined is returned.

var result = jsObjects.find(obj => {
  return obj.b === 6
})

See the MDN Docs on Array.prototype.find()

const jsObjects = [_x000D_
  {a: 1, b: 2}, _x000D_
  {a: 3, b: 4}, _x000D_
  {a: 5, b: 6}, _x000D_
  {a: 7, b: 8}_x000D_
]_x000D_
_x000D_
let result = jsObjects.find(obj => {_x000D_
  return obj.b === 6_x000D_
})_x000D_
_x000D_
console.log(result)

Firebase Cloud Messaging has a server-side APIs that you can call to send messages. See https://firebase.google.com/docs/cloud-messaging/server.

Sending a message can be as simple as using curl to call a HTTP end-point. See https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol

curl -X POST --header "Authorization: key=<API_ACCESS_KEY>" \
    --Header "Content-Type: application/json" \

    -d "{\"to\":\"<YOUR_DEVICE_ID_TOKEN>\",\"notification\":{\"title\":\"Hello\",\"body\":\"Yellow\"}}"

For me, and other newbies who has just contacted with Javascript,
I think that the Closeure Solution is a little kind of too confusing.

While I found that, you can easilly pass as many parameters as you want to every ajax callback using jquery.

Here are two easier solutions.

First one, which @zeroasterisk has mentioned above, example:

var $items = $('.some_class');
$.each($items, function(key, item){
    var url = 'http://request_with_params' + $(item).html();
    $.ajax({
        selfDom     : $(item),
        selfData    : 'here is my self defined data',

        url         : url,
        dataType    : 'json',
        success     : function(data, code, jqXHR){
            // in $.ajax callbacks, 
            // [this] keyword references to the options you gived to $.ajax
            // if you had not specified the context of $.ajax callbacks.
            // see http://api.jquery.com/jquery.ajax/#jQuery-ajax-settings context
            var $item = this.selfDom;
            var selfdata = this.selfData;
            $item.html( selfdata );
            ...
        } 
    });
});

Second one, pass self-defined-datas by adding them into the XHR object which exists in the whole ajax-request-response life span.

var $items = $('.some_class');
$.each($items, function(key, item){
    var url = 'http://request_with_params' + $(item).html();
    $.ajax({
        url         : url,
        dataType    : 'json',
        beforeSend  : function(XHR) {
            // ??????,???? jquery??????? XHR
            XHR.selfDom = $(item);
            XHR.selfData = 'here is my self defined data';
        },
        success     : function(data, code, jqXHR){
            // jqXHR is a superset of the browser's native XHR object
            var $item = jqXHR.selfDom;
            var selfdata = jqXHR.selfData;
            $item.html( selfdata );
            ...
        } 
    });
});

As you can see these two solutions has a drawback that : you need write a little more code every time than just write:

$.get/post (url, data, successHandler);

How about something like:

plot.new()

The problem I was having with the rewrite is that some .htaccess files for Codeigniter, etc come with

RewriteBase /

Which doesn't seem to work in MAMP...at least for me.

Easiest way is to start a WinForms application, go to settings and change the type to a console application.

Hard to say because it depends on what you want the parser to extract from your YAML document. For simple cases, you might be able to use grep, cut, awk etc. For more complex parsing you would need to use a full-blown parsing library such as Python's PyYAML or YAML::Perl.

This is my solution using the wrapper, just removing border-collapse might not be helpful always, because you might want to have borders.

Collections is a utility class, meaning that it defines a set of methods that perform common, often re-used functions, such as sorting a list, rotating a list, finding the minimum value etc. And these common methods are defined under static scope.

Collection is an interface that is implemented by AbstractCollection which in turn is implemented by AbstractList, AbstractSet etc.

Also, Collections class has thirty-two convenience implementations of its collection interfaces, providing unmodifiable collections, synchronized collections. Nearly all of these implementations are exported via static factory methods in one noninstantiable class (java.util.Collections).

Sometimes this error comes, when HTML has some commented code and browser is trying to look for something. Like in my case I had commented code for a web form in flask and I was getting this.

After spending 2 hours I fixed it in the following ways:

1) I created a new python environment and then it threw an error on the commented HTML line, before this I was only thrown error 'GET /favicon.ico HTTP/1.1" 404'

2) Sometimes, when I had a duplicate code, like python file existing with the same name, then also I saw this error, try removing those too

This thread is pretty old I suppose, but in case anyone else stumbles across this question... I had to grab a value from the selected row of a table, but I didn't want to show the column that row was from. I used hideCol, but had the same problem as Andy where it looked messy. To fix it (call it a hack) I just re-set the width of the grid.

jQuery(document).ready(function() {

       jQuery("#ItemGrid").jqGrid({ 
                ..., 
                width: 700,
                ...
        }).hideCol('StoreId').setGridWidth(700)

Since my row widths are automatic, when I reset the width of the table it reset the column widths but excluded the hidden one, so they filled in the gap.

You can do this with LibreOffice:

libreoffice --headless --convert-to csv $filename --outdir $outdir

For reasons not clear to me, you might need to run this with sudo. You can make LibreOffice work with sudo without requiring a password by adding this line to you sudoers file:

Some explain from C++Primer 5th Page 35

If we assign an out-of-range value to an object of unsigned type, the result is the remainder of the value modulo the number of values the target type can hold.

For example, an 8-bit unsigned char can hold values from 0 through 255, inclusive. If we assign a value outside the range, the compiler assigns the remainder of that value modulo 256.

unsigned char c = -1; // assuming 8-bit chars, c has value 255

If we assign an out-of-range value to an object of signed type, the result is undefined. The program might appear to work, it might crash, or it might produce garbage values.

Page 160: If any operand is an unsigned type, the type to which the operands are converted depends on the relative sizes of the integral types on the machine.

... When the signedness differs and the type of the unsigned operand is the same as or larger than that of the signed operand, the signed operand is converted to unsigned.

The remaining case is when the signed operand has a larger type than the unsigned operand. In this case, the result is machine dependent. If all values in the unsigned type fit in the large type, then the unsigned operand is converted to the signed type. If the values don't fit, then the signed operand is converted to the unsigned type.

For example, if the operands are long and unsigned int, and int and long have the same size, the length will be converted to unsigned int. If the long type has more bits, then the unsigned int will be converted to long.

I found reading this book is very helpful.

• In that case using method isset is not appropriate.

According to PHP documentation: http://php.net/manual/en/function.array-key-exists.php
(see Example #2 array_key_exists() vs isset())
The method array_key_exists is intended for checking key presence in array.

So code in the question could be changed as follow:

function fromPerson() {
   if (array_key_exists('fromPerson', $_POST) == FALSE) {
        return '';
   } else {
        return '+from%3A'.$_POST['fromPerson'];
   };
}

$newString = fromPerson();

• Checking presence of array $_POST is not necessary because it is PHP environment global variable since version 4.1.0 (nowadays we does not meet older versions of PHP).

Convert PPK to OpenSSh

OS X: Install Homebrew, then run

brew install putty

Place your keys in some directory, e.g. your home folder. Now convert the PPK keys to SSH keypairs:cache search

To generate the private key:

cd ~

puttygen id_dsa.ppk -O private-openssh -o id_dsa

and to generate the public key:

puttygen id_dsa.ppk -O public-openssh -o id_dsa.pub

Move these keys to ~/.ssh and make sure the permissions are set to private for your private key:

mkdir -p ~/.ssh
mv -i ~/id_dsa* ~/.ssh
chmod 600 ~/.ssh/id_dsa
chmod 666 ~/.ssh/id_dsa.pub

connect with ssh server

ssh -i ~/.ssh/id_dsa username@servername

Port Forwarding to connect mysql remote server

ssh -i ~/.ssh/id_dsa -L 9001:127.0.0.1:3306 username@serverName

Try this: Left-click the tab, making a copy of the whole sheet, then cut the cells you want to keep the same and paste them into your original worksheet.

private static byte[] charArrayToByteArray(char[] c_array) {
        byte[] b_array = new byte[c_array.length];
        for(int i= 0; i < c_array.length; i++) {
            b_array[i] = (byte)(0xFF & (int)c_array[i]);
        }
        return b_array;
}

Alright, I deserve to be throttled. definitely an RTM but not for WooCommerce, for Wordpress. Solution found due to a JOLT cola (all hail JOLT cola).

TASK: Field named 'related_product_ids' added to a custom post type. So when that post is displayed mini product displays can be displayed with it.

PROBLEM: Was having a problem getting the multiple ids returned via WP_Query.

SOLUTION:

$related_id_list          = get_post_custom_values('related_product_ids');
    // Get comma delimited list from current post
$related_product_ids      = explode(",", trim($related_id_list[0],','));
    // Return an array of the IDs ensure no empty array elements from extra commas
$related_product_post_ids = array( 'post_type' => 'product', 
                                   'post__in'  => $related_product_ids,
                                   'meta_query'=> array( 
                                        array( 'key'    => '_visibility',
                                               'value'  => array('catalog', 'visible'),'compare' => 'IN'
                                        )
                            ) 
);      
    // Query to get all product posts matching given IDs provided it is a published post
$loop = new WP_Query( $related_posts );
    // Execute query
while ( $loop->have_posts() ) : $loop->the_post(); $_product = get_product( $loop->post->ID );
    // Do stuff here to display your products 
endwhile;

Thank you for anyone who may have spent some time on this.

Try VIM

If you have vim you can use this:

Not tested for every encoding.

The cool part about this is that you don't have to know the source encoding

vim +"set nobomb | set fenc=utf8 | x" filename.txt

Be aware that this command modify directly the file

Explanation part!

1. + : Used by vim to directly enter command when opening a file. Usualy used to open a file at a specific line: vim +14 file.txt
2. | : Separator of multiple commands (like ; in bash)
3. set nobomb : no utf-8 BOM
4. set fenc=utf8 : Set new encoding to utf-8 doc link
5. x : Save and close file
6. filename.txt : path to the file
7. " : qotes are here because of pipes. (otherwise bash will use them as bash pipe)

public class SmsListener extends BroadcastReceiver{

    private SharedPreferences preferences;

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
            Bundle bundle = intent.getExtras();           //---get the SMS message passed in---
            SmsMessage[] msgs = null;
            String msg_from;
            if (bundle != null){
                //---retrieve the SMS message received---
                try{
                    Object[] pdus = (Object[]) bundle.get("pdus");
                    msgs = new SmsMessage[pdus.length];
                    for(int i=0; i<msgs.length; i++){
                        msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                        msg_from = msgs[i].getOriginatingAddress();
                        String msgBody = msgs[i].getMessageBody();
                    }
                }catch(Exception e){
//                            Log.d("Exception caught",e.getMessage());
                }
            }
        }
    }
}

Note: In your manifest file add the BroadcastReceiver-

<receiver android:name=".listener.SmsListener">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

Add this permission:

<uses-permission android:name="android.permission.RECEIVE_SMS" />

This demo is returning correctly for me in Chrome 14, FF3 and FF5 (with Firebug):

var mytextvalue = document.getElementById("mytext").value;
console.log(mytextvalue == ''); // true
console.log(mytextvalue == null); // false

and changing the console.log to alert, I still get the desired output in IE6.
