See my comment above asking for clarification on what you really want. Hopefully this is it:

System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.Diagnostics.FileVersionInfo fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);
string version = fvi.FileVersion;

Copying from a command line is unnecessary. I typed in the name of the DLL from the Start Window search. I chose See More Results. The one in the GAC was returned in the search window. I right clicked on it and said open file location. It opened in normal Windows Explorer. I copied the file. I closed the window. Done.

Another way to check the target platform of a .NET assembly is inspecting the assembly with .NET Reflector...

@#~#€~! I've just realized that the new version is not free! So, correction, if you have a free version of .NET reflector, you can use it to check the target platform.

Assuming you alredy tried to "Add Reference..." as explained above and did not succeed, you can have a look here. They say you have to meet some prerequisites: - .NET 3.5 SP1 - Windows Installer 4.5

EDIT: According to this post it is a known issue.

And this could be the solution you're looking for :)

AssemblyVersion

Where other assemblies that reference your assembly will look. If this number changes, other assemblies have to update their references to your assembly! Only update this version, if it breaks backward compatibility. The AssemblyVersion is required.

I use the format: major.minor. This would result in:

[assembly: AssemblyVersion("1.0")]

If you're following SemVer strictly then this means you only update when the major changes, so 1.0, 2.0, 3.0, etc.

AssemblyFileVersion

Used for deployment. You can increase this number for every deployment. It is used by setup programs. Use it to mark assemblies that have the same AssemblyVersion, but are generated from different builds.

In Windows, it can be viewed in the file properties.

The AssemblyFileVersion is optional. If not given, the AssemblyVersion is used.

I use the format: major.minor.patch.build, where I follow SemVer for the first three parts and use the buildnumber of the buildserver for the last part (0 for local build). This would result in:

[assembly: AssemblyFileVersion("1.3.2.254")]

Be aware that System.Version names these parts as major.minor.build.revision!

AssemblyInformationalVersion

The Product version of the assembly. This is the version you would use when talking to customers or for display on your website. This version can be a string, like '1.0 Release Candidate'.

The AssemblyInformationalVersion is optional. If not given, the AssemblyFileVersion is used.

I use the format: major.minor[.patch] [revision as string]. This would result in:

[assembly: AssemblyInformationalVersion("1.0 RC1")]

Yes. I don't have any examples that I've done personally available right now. I'll post later when I find some. Basically you'll use reflection to load the assembly and then to pull whatever types you need for it.

In the meantime, this link should get you started:

Using reflection to load unreferenced assemblies at runtime

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

Try the following: In Visual Studio, go to Tools/Options....Projects and Solutions...Web Projects... Make sure that 64 bit version of IIS Express checkbox is checked off.

Signing the third party assembly worked for me:

http://www.codeproject.com/Tips/341645/Referenced-assembly-does-not-have-a-strong-name

EDIT: I've learned that it's helpful to post steps in case the linked article is no longer valid. All credit goes to Hiren Khirsaria:

1. Run visual studio command prompt and go to directory where your DLL located.

   For Example my DLL is located in D:/hiren/Test.dll

2. Now create the IL file using the command below.

   D:/hiren> ildasm /all /out=Test.il Test.dll (this command generates the code library)

3. Generate new key to sign your project.

   D:/hiren> sn -k mykey.snk

4. Now sign your library using ilasm command.

   D:/hiren> ilasm /dll /key=mykey.snk Test.il

I usually use the Fusion Log Viewer (Fuslogvw.exe from a Visual Studio command prompt or Fusion Log Viewer from the start menu) - my standard setup is:

• Open Fusion Log Viewer as administrator
• Click settings
• Check the Enable custom log path checkbox
• Enter the location you want logs to get written to, for example, c:\FusionLogs (Important: make sure that you have actually created this folder in the file system.)
• Make sure that the right level of logging is on (I sometimes just select Log all binds to disk just to make sure things are working right)
• Click OK
• Set the log location option to Custom

Remember to turn of logging off once you're done!

(I just posted this on a similar question - I think it's relevant here too.)

Once you pass the assembly instance back to the caller domain, the caller domain will try to load it! This is why you get the exception. This happens in your last line of code:

domain.Load(AssemblyName.GetAssemblyName(path));

Thus, whatever you want to do with the assembly, should be done in a proxy class - a class which inherit MarshalByRefObject.

Take in count that the caller domain and the new created domain should both have access to the proxy class assembly. If your issue is not too complicated, consider leaving the ApplicationBase folder unchanged, so it will be same as the caller domain folder (the new domain will only load Assemblies it needs).

In simple code:

public void DoStuffInOtherDomain()
{
    const string assemblyPath = @"[AsmPath]";
    var newDomain = AppDomain.CreateDomain("newDomain");
    var asmLoaderProxy = (ProxyDomain)newDomain.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, typeof(ProxyDomain).FullName);

    asmLoaderProxy.GetAssembly(assemblyPath);
}

class ProxyDomain : MarshalByRefObject
{
    public void GetAssembly(string AssemblyPath)
    {
        try
        {
            Assembly.LoadFrom(AssemblyPath);
            //If you want to do anything further to that assembly, you need to do it here.
        }
        catch (Exception ex)
        {
            throw new InvalidOperationException(ex.Message, ex);
        }
    }
}

If you do need to load the assemblies from a folder which is different than you current app domain folder, create the new app domain with specific dlls search path folder.

For example, the app domain creation line from the above code should be replaced with:

var dllsSearchPath = @"[dlls search path for new app domain]";
AppDomain newDomain = AppDomain.CreateDomain("newDomain", new Evidence(), dllsSearchPath, "", true);

This way, all the dlls will automaically be resolved from dllsSearchPath.

In my case it was a project defined using Target Framework: ".NET Framework 4.0 Client Profile " that tried to reference dll projects defined using Target Framework: ".NET Framework 4.0".

Once I changed the project settings to use Target Framework: ".NET Framework 4.0" everything was built nicely.

Right Click the project->Properties->Application->Target Framework

Since Qt 5.8, we now have QDateTime::currentSecsSinceEpoch() to deliver the seconds directly, a.k.a. as real Unix timestamp. So, no need to divide the result by 1000 to get seconds anymore.

Credits: also posted as comment to this answer. However, I think it is easier to find if it is a separate answer.

It would be nice if there were some way of turning off "throw on non-success code" but if you catch WebException you can at least use the response:

using System;
using System.IO;
using System.Web;
using System.Net;

public class Test
{
    static void Main()
    {
        WebRequest request = WebRequest.Create("http://csharpindepth.com/asd");
        try
        {
            using (WebResponse response = request.GetResponse())
            {
                Console.WriteLine("Won't get here");
            }
        }
        catch (WebException e)
        {
            using (WebResponse response = e.Response)
            {
                HttpWebResponse httpResponse = (HttpWebResponse) response;
                Console.WriteLine("Error code: {0}", httpResponse.StatusCode);
                using (Stream data = response.GetResponseStream())
                using (var reader = new StreamReader(data))
                {
                    string text = reader.ReadToEnd();
                    Console.WriteLine(text);
                }
            }
        }
    }
}

You might like to encapsulate the "get me a response even if it's not a success code" bit in a separate method. (I'd suggest you still throw if there isn't a response, e.g. if you couldn't connect.)

If the error response may be large (which is unusual) you may want to tweak HttpWebRequest.DefaultMaximumErrorResponseLength to make sure you get the whole error.

For flexibility and other places you might want to validated. You can use the following function.

`function validateOnlyTextField(element) {
    var str = element.value;
    if(!(/^[a-zA-Z, ]+$/.test(str))){
        // console.log('String contain number characters');
        str = str.substr(0,  str.length -1);
        element.value = str;
    }
}`

Then on your html section use the following event.

<input type="text" id="names" onkeyup="validateOnlyTextField(this)" />

You can always reuse the function.

 <style name="WhiteTextWithShadow" parent="@android:style/TextAppearance">
    <item name="android:shadowDx">1</item>
    <item name="android:shadowDy">1</item>
    <item name="android:shadowRadius">1</item>
    <item name="android:shadowColor">@android:color/black</item>
    <item name="android:textColor">@android:color/white</item>
</style>

then use as

 <TextView
            android:id="@+id/text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="15sp"
            tools:text="Today, May 21"
            style="@style/WhiteTextWithShadow"/>

I think that they should perform generally the same, but there are some differences. START is generally used to start applications or to start the default application for a given file type. That way if you START http://mywebsite.com it doesn't do START iexplore.exe http://mywebsite.com.

START myworddoc.docx would start Microsoft Word and open myworddoc.docx.CALL myworddoc.docx does the same thing... however START provides more options for the window state and things of that nature. It also allows process priority and affinity to be set.

In short, given the additional options provided by start, it should be your tool of choice.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
  [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
  [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
  [command/program] [parameters]

"title"     Title to display in window title bar.
path        Starting directory.
B           Start application without creating a new window. The
            application has ^C handling ignored. Unless the application
            enables ^C processing, ^Break is the only way to interrupt
            the application.
I           The new environment will be the original environment passed
            to the cmd.exe and not the current environment.
MIN         Start window minimized.
MAX         Start window maximized.
SEPARATE    Start 16-bit Windows program in separate memory space.
SHARED      Start 16-bit Windows program in shared memory space.
LOW         Start application in the IDLE priority class.
NORMAL      Start application in the NORMAL priority class.
HIGH        Start application in the HIGH priority class.
REALTIME    Start application in the REALTIME priority class.
ABOVENORMAL Start application in the ABOVENORMAL priority class.
BELOWNORMAL Start application in the BELOWNORMAL priority class.
NODE        Specifies the preferred Non-Uniform Memory Architecture (NUMA)
            node as a decimal integer.
AFFINITY    Specifies the processor affinity mask as a hexadecimal number.
            The process is restricted to running on these processors.

            The affinity mask is interpreted differently when /AFFINITY and
            /NODE are combined.  Specify the affinity mask as if the NUMA
            node's processor mask is right shifted to begin at bit zero.
            The process is restricted to running on those processors in
            common between the specified affinity mask and the NUMA node.
            If no processors are in common, the process is restricted to
            running on the specified NUMA node.
WAIT        Start application and wait for it to terminate.

I do not know much about JavaScript, but I think Timers may be what you are looking for.

http://developer.android.com/reference/java/util/Timer.html

From the link:

One-shot are scheduled to run at an absolute time or after a relative delay. Recurring tasks are scheduled with either a fixed period or a fixed rate.

Assuming that you have your data in a 2d array, this should work:

import numpy
import pylab
xy = numpy.zeros((2, 1000))
xy[0] = range(1000)
xy[1] = range(1000)
colors = [int(i % 23) for i in xy[0]]
pylab.scatter(xy[0], xy[1], c=colors)
pylab.show()

You can also set a cmap attribute to control which colors will appear through use of a colormap; i.e. replace the pylab.scatter line with:

pylab.scatter(xy[0], xy[1], c=colors, cmap=pylab.cm.cool)

A list of color maps can be found here

@techedemic is correct but is missing '.' to mention the current directory, and this command go throught all subdirectories.

find . -name '*.gz' -exec gunzip '{}' \;

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

You can find out the Android version looking at Build.VERSION.

The documentation recommends you check Build.VERSION.SDK_INT against the values in Build.VERSION_CODES.

This is fine as long as you realise that Build.VERSION.SDK_INT was only introduced in API Level 4, which is to say Android 1.6 (Donut). So this won't affect you, but if you did want your app to run on Android 1.5 or earlier then you would have to use the deprecated Build.VERSION.SDK instead.

First install pyyaml using pip3.

Then import yaml module and load the file into a dictionary called 'my_dict':

import yaml
with open('filename.yaml') as f:
    my_dict = yaml.safe_load(f)

That's all you need. Now the entire yaml file is in 'my_dict' dictionary.

Try

 a{
    line-height: 0; 
    font-size: 0;
    color: transparent; 
 }

The color: transparent; covers an issue with Webkit browsers still displaying 1px of the text.

If u r using SQLite3 beware:

It takes only 't' or 'f'. Not 1 or 0. Not TRUE OR FALSE.

Just learned the hard way.

If all you need is mousedown, you may be able to make do with the document.elementFromPoint method, by:

1. removing the top layer on mousedown,
2. passing the x and y coordinates from the event to the document.elementFromPoint method to get the element underneath, and then
3. restoring the top layer.

To further work with array of maps, the followings could help:

@RequestMapping(value = "/process", method = RequestMethod.POST, headers = "Accept=application/json")
public void setLead(@RequestBody Collection<? extends Map<String, Object>> payload) throws Exception {

  List<Map<String,Object>> maps = new ArrayList<Map<String,Object>>();
  maps.addAll(payload);

}

For a PDF that ImageMagick was giving inaccurate colors I found that GraphicsMagick did a better job:

Set ScrollView layout_height as a wrap_content then it will work fine. Below are example which may help someone. I have used compile 'com.android.support.constraint:constraint-layout:1.0.2' for constraint layout.

I think you have to define the timestamp column like this

CREATE TABLE t1 
(
    ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

See here

Warning: The following is only suitable for small tables (think < 1000 rows)

Here is a solution that uses entity framework (not SQL) to delete the rows, so it is not SQL Engine(R/DBM) specific.

This assumes that you're doing this for testing or some similar situation. Either

• The amount of data is small or
• The performance doesn't matter

Simply call:

VotingContext.Votes.RemoveRange(VotingContext.Votes);

Assuming this context:

public class VotingContext : DbContext
{
    public DbSet<Vote> Votes{get;set;}
    public DbSet<Poll> Polls{get;set;}
    public DbSet<Voter> Voters{get;set;}
    public DbSet<Candidacy> Candidates{get;set;}
}

For tidier code you can declare the following extension method:

public static class EntityExtensions
{
    public static void Clear<T>(this DbSet<T> dbSet) where T : class
    {
        dbSet.RemoveRange(dbSet);
    }
}

Then the above becomes:

VotingContext.Votes.Clear();
VotingContext.Voters.Clear();
VotingContext.Candidacy.Clear();
VotingContext.Polls.Clear();
await VotingTestContext.SaveChangesAsync();

I recently used this approach to clean up my test database for each testcase run (it´s obviously faster than recreating the DB from scratch each time, though I didn´t check the form of the delete commands that were generated).

Why can it be slow?

1. EF will get ALL the rows (VotingContext.Votes)
2. and then will use their IDs (not sure exactly how, doesn't matter), to delete them.

So if you're working with serious amount of data you'll kill the SQL server process (it will consume all the memory) and same thing for the IIS process since EF will cache all the data same way as SQL server. Don't use this one if your table contains serious amount of data.

Just add this after jQuery loads and before your code.

$(window).ajaxComplete(function () {console.log('Ajax Complete'); });
$(window).ajaxError(function (data, textStatus, jqXHR) {console.log('Ajax Error');
    console.log('data: ' + data);
    console.log('textStatus: ' + textStatus);
        console.log('jqXHR: ' + jqXHR); });
$(window).ajaxSend(function () {console.log('Ajax Send'); });
$(window).ajaxStart(function () {console.log('Ajax Start'); });
$(window).ajaxStop(function () {console.log('Ajax Stop'); });
$(window).ajaxSuccess(function () {console.log('Ajax Success'); });

To extract the year from current date

SELECT YEAR(CURRENT_DATE())

IBM Netezza

extract(year from now())

HIVE

SELECT YEAR(CURRENT_DATE())

IDP Initiated SSO

From PingFederate documentation :- https://docs.pingidentity.com/bundle/pf_sm_supportedStandards_pf82/page/task/idpInitiatedSsoPOST.html

In this scenario, a user is logged on to the IdP and attempts to access a resource on a remote SP server. The SAML assertion is transported to the SP via HTTP POST.

Processing Steps:

1. A user has logged on to the IdP.
2. The user requests access to a protected SP resource. The user is not logged on to the SP site.
3. Optionally, the IdP retrieves attributes from the user data store.
4. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP.

SP Initiated SSO

From PingFederate documentation:- http://documentation.pingidentity.com/display/PF610/SP-Initiated+SSO--POST-POST

In this scenario a user attempts to access a protected resource directly on an SP Web site without being logged on. The user does not have an account on the SP site, but does have a federated account managed by a third-party IdP. The SP sends an authentication request to the IdP. Both the request and the returned SAML assertion are sent through the user’s browser via HTTP POST.

Processing Steps:

1. The user requests access to a protected SP resource. The request is redirected to the federation server to handle authentication.
2. The federation server sends an HTML form back to the browser with a SAML request for authentication from the IdP. The HTML form is automatically posted to the IdP’s SSO service.
3. If the user is not already logged on to the IdP site or if re-authentication is required, the IdP asks for credentials (e.g., ID and password) and the user logs on.

4. Additional information about the user may be retrieved from the user data store for inclusion in the SAML response. (These attributes are predetermined as part of the federation agreement between the IdP and the SP)

5. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP. NOTE: SAML specifications require that POST responses be digitally signed.

6. (Not shown) If the signature and assertion are valid, the SP establishes a session for the user and redirects the browser to the target resource.

In this case, I'd recommend using break labels.

This way you can specifically call it outside of the for loop.

You might need to install SQL Server 2008 SP3.

SQL Server 2008 Service Pack 3

SQL Server 2012 Configuration Manager WMI Error – Remote Procedure call failed [0x800706be]

For June 1 2017

Certain combined steps from answer of this thread that worked for me. I am writing the process that worked fine for me.

1) Open terminal and run this

cd ~

mv .itmstransporter/ .old_itmstransporter/

"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"

iTMSTransporter will then update itself, wait till process completes.

2) Logout the apple account from Xcode preferences account and login again instead of creating new Id on iTunes and developer account.

3) Clean the project and archive then export the app from organiser as an IPA for app store distribution.

4) Logging into application loader with same account and upload the ipa.

5) Process will complete successfully.

removeProperty will remove a style from an element.

Example:

div.style.removeProperty('zoom');

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform, sys
>>> platform.architecture(), sys.maxsize
(('64bit', ''), 2147483647)
>>> ^D
$ arch -x86_64 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform, sys
>>> platform.architecture(), sys.maxsize

It looks like you are calling next even if the scanner no longer has a next element to provide... throwing the exception.

while(!file.next().equals(treasure)){
        file.next();
        }

Should be something like

boolean foundTreasure = false;

while(file.hasNext()){
     if(file.next().equals(treasure)){
          foundTreasure = true;
          break; // found treasure, if you need to use it, assign to variable beforehand
     }
}
    // out here, either we never found treasure at all, or the last element we looked as was treasure... act accordingly

We had the same issue when we had a typo in the mybatis mapping file like

        ....
        #{column1Name,          jdbcType=INTEGER},
        #{column2Name,          jdbcType=VARCHAR},
        #{column3Name,      jdbcTyep=VARCHAR}  -- do you see the typo ?
        .....

So check this kind of typos as well. Unfortunately, it can not understand the typo in compile/build time, it causes an unchecked exception and booms in runtime.

An official example notebook demonstrating local file upload/download and integration with Drive and sheets is available here: https://colab.research.google.com/notebooks/io.ipynb

The simplest way to share files is to mount your Google Drive.

To do this, run the following in a code cell:

from google.colab import drive
drive.mount('/content/drive')

It will ask you to visit a link to ALLOW "Google Files Stream" to access your drive. After that a long alphanumeric auth code will be shown that needs to be entered in your Colab's notebook.

Afterward, your Drive files will be mounted and you can browse them with the file browser in the side panel.

Here's a full example notebook

you must add 1 day to the end date, using: DATE_ADD('$end_date', INTERVAL 1 DAY)

DllImport will work fine without the complete path specified as long as the dll is located somewhere on the system path. You may be able to temporarily add the user's folder to the path.

Based on the fact that longitude lines are spaced apart equally at any point of the map, there is a very simple implementation to set the centerCoordinate and zoomLevel:

@interface MKMapView (ZoomLevel)

@property (assign, nonatomic) NSUInteger zoomLevel;

- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
                  zoomLevel:(NSUInteger)zoomLevel
                   animated:(BOOL)animated;

@end


@implementation MKMapView (ZoomLevel)

- (void)setZoomLevel:(NSUInteger)zoomLevel {
    [self setCenterCoordinate:self.centerCoordinate zoomLevel:zoomLevel animated:NO];
}

- (NSUInteger)zoomLevel {
    return log2(360 * ((self.frame.size.width/256) / self.region.span.longitudeDelta)) + 1;
}

- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
zoomLevel:(NSUInteger)zoomLevel animated:(BOOL)animated {
    MKCoordinateSpan span = MKCoordinateSpanMake(0, 360/pow(2, zoomLevel)*self.frame.size.width/256);
    [self setRegion:MKCoordinateRegionMake(centerCoordinate, span) animated:animated];
}

@end

You could use String.prototype.indexOf to accomplish that. Try something like this:

$('.type').keyup(function() {_x000D_
  var v = $(this).val();_x000D_
  if (v.indexOf('> <') !== -1) {_x000D_
    console.log('contains > <');_x000D_
  }_x000D_
  console.log(v);_x000D_
});

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

Update

Modern browsers also have a String.prototype.includes method.

There's very little reason not to open multiple workbooks in Excel. Key lines of code are:

Application.EnableEvents = False
Application.ScreenUpdating = False

...then you won't see anything whilst the code runs, and no code will run that is associated with the opening of the second workbook. Then there are...

Application.DisplayAlerts = False
Application.Calculation = xlManual

...so as to stop you getting pop-up messages associated with the content of the second file, and to avoid any slow re-calculations. Ensure you set back to True/xlAutomatic at end of your programming

If opening the second workbook is not going to cause performance issues, you may as well do it. In fact, having the second workbook open will make it very beneficial when attempting to debug your code if some of the secondary files do not conform to the expected format

Here is some expert guidance on using multiple Excel files that gives an overview of the different methods available for referencing data

An extension question would be how to cycle through multiple files contained in the same folder. You can use the Windows folder picker using:

With Application.FileDialog(msoFileDialogFolderPicker)
.Show
     If .Selected.Items.Count = 1 the InputFolder = .SelectedItems(1)
End With

FName = VBA.Dir(InputFolder)

Do While FName <> ""
'''Do function here
FName = VBA.Dir()
Loop

Hopefully some of the above will be of use

I tried every method listed here and in Android adb devices unauthorized

What eventually worked for me was the option just below USB Debugging 'Revoke auths'

Yes, but none of them will manage to produce readable enough code to worth the effort. You will spend more time trying to read the decompiled source with assembler blocks inside, than rewriting your old app from scratch.

You have several options. The first is to increase the availble memory allowed, which is probably not the best way to do things given that you state the file can get very large. The other way is to use fgets to read the file line by line and increment a counter, which should not cause any memory issues at all as only the current line is in memory at any one time.

$users = get-childitem \\ServerName\c$\users\ | select -ExpandProperty name

foreach ($user in $users)

{
remove-item -path "\\Servername\c$\Users\$user\AppData\Local\Microsoft\Office365\PowerShell\*" -Force -Recurse

}

Wrote the above to clean some logfiles without deleting the parent directory and this works perfectly!

I will just leave it here, just rewrote the code above using numpy, maybe somebody finds it useful:

def ray_tracing_numpy(x,y,poly):
    n = len(poly)
    inside = np.zeros(len(x),np.bool_)
    p2x = 0.0
    p2y = 0.0
    xints = 0.0
    p1x,p1y = poly[0]
    for i in range(n+1):
        p2x,p2y = poly[i % n]
        idx = np.nonzero((y > min(p1y,p2y)) & (y <= max(p1y,p2y)) & (x <= max(p1x,p2x)))[0]
        if p1y != p2y:
            xints = (y[idx]-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
        if p1x == p2x:
            inside[idx] = ~inside[idx]
        else:
            idxx = idx[x[idx] <= xints]
            inside[idxx] = ~inside[idxx]    

        p1x,p1y = p2x,p2y
    return inside    

Wrapped ray_tracing into

def ray_tracing_mult(x,y,poly):
    return [ray_tracing(xi, yi, poly[:-1,:]) for xi,yi in zip(x,y)]

Tested on 100000 points, results:

ray_tracing_mult 0:00:00.850656

            int flag = 0;
            var property = GetProperty(list.FirstOrDefault(), attribute);
            foreach (T obj in list)
            {
                if (property.GetValue(obj, null) == null)
                    flag++;
            }
            status = flag == 0 ? true : false;
        }
        return status;
    }


public PropertyInfo GetProperty<T>(T obj, string str)

    {
        Expression<Func<T, string, PropertyInfo>> GetProperty = (TypeObj, Column) => TypeObj.GetType().GetProperty(TypeObj
            .GetType().GetProperties().ToList()
            .Find(property => property.Name
            .ToLower() == Column
            .ToLower()).Name.ToString());
        return GetProperty.Compile()(obj, str);
    }

Actually there is an operator for that in PostgreSQL:

SELECT *
FROM table
WHERE lower(value) ~~ ANY('{%foo%,%bar%,%baz%}');

After looking at all solutions, I realised there is a much simpler solution.

In your activity's onBackPressed() that is hosting all your fragments, find the fragment that you want to prevent back press. Then if found, just return. Then popBackStack will never happen for this fragment.

  @Override
public void onBackPressed() {

        Fragment1 fragment1 = (Fragment1) getFragmentManager().findFragmentByTag(“Fragment1”);
        if (fragment1 != null)
            return;

        if (getFragmentManager().getBackStackEntryCount() > 0){
            getFragmentManager().popBackStack();

        }
}

Well, as now in Jan, 2018, the best way for this is to use apache's BooleanUtils.toBoolean.

This will convert any boolean like string to boolean, e.g. Y, yes, true, N, no, false, etc.

Really handy!

I know this topic is a bit old, but I think I did something that may be useful for someone, so I'm posting it.

I compiled suggestions from this thread's answers into a procedure:

CREATE OR REPLACE PROCEDURE create_table_if_doesnt_exist(
  p_table_name VARCHAR2,
  create_table_query VARCHAR2
) AUTHID CURRENT_USER IS
  n NUMBER;
BEGIN
  SELECT COUNT(*) INTO n FROM user_tables WHERE table_name = UPPER(p_table_name);
  IF (n = 0) THEN
    EXECUTE IMMEDIATE create_table_query;
  END IF;
END;

You can then use it in a following way:

call create_table_if_doesnt_exist('my_table', 'CREATE TABLE my_table (
        id NUMBER(19) NOT NULL PRIMARY KEY,
        text VARCHAR2(4000),
        modified_time TIMESTAMP
  )'
);

I know that it's kinda redundant to pass table name twice, but I think that's the easiest here.

Hope somebody finds above useful :-).

In the newer version that is > 2.2 you can use git restore --staged <file_name>. Note here If you want to unstage (move to changes) your files one at a time you use above command with your file name. eg

git restore --staged abc.html

Now if you want unstage all your file at once, you can do something like this

git restore --staged .

Please note space and dot (.) which means consider staged all files.

We can implement by 3 Methods:

Note:

"automatic-scroll" => The particular element

"scrollable-div" => The scrollable area div

Method 1:

document.querySelector('.automatic-scroll').scrollIntoView({
     behavior: 'smooth'
});

Method 2:

location.href = "#automatic-scroll";

Method 3:

$('#scrollable-div').animate({
   scrollTop: $('#automatic-scroll').offset().top - $('#scrollable-div').offset().top + 
   $('#scrollable-div').scrollTop()
})

Important notice: method 1 & method 2 will be useful if the scrollable area height is "auto". Method 3 is useful if we using the scrollable area height like "calc(100vh - 200px)".

xxdiff is lightweight if that's what you're after.

As Dumb Guy points out, it's important to note whether the array starts at zero and is sequential. Since you can make assignments to and unset non-contiguous indices ${#array[@]} is not always the next item at the end of the array.

$ array=(a b c d e f g h)
$ array[42]="i"
$ unset array[2]
$ unset array[3]
$ declare -p array     # dump the array so we can see what it contains
declare -a array='([0]="a" [1]="b" [4]="e" [5]="f" [6]="g" [7]="h" [42]="i")'
$ echo ${#array[@]}
7
$ echo ${array[${#array[@]}]}
h

Here's how to get the last index:

$ end=(${!array[@]})   # put all the indices in an array
$ end=${end[@]: -1}    # get the last one
$ echo $end
42

That illustrates how to get the last element of an array. You'll often see this:

$ echo ${array[${#array[@]} - 1]}
g

As you can see, because we're dealing with a sparse array, this isn't the last element. This works on both sparse and contiguous arrays, though:

$ echo ${array[@]: -1}
i

>>> map(myList.__getitem__, (2,2,1,3))
('baz', 'baz', 'bar', 'quux')

You can also create your own List class which supports tuples as arguments to __getitem__ if you want to be able to do myList[(2,2,1,3)].

SourceTree users

If you use SourceTree to visualize your repository (it's free and quite good) you can right click a file and select Log Selected

The display (below) is much friendlier than gitk and most the other options listed. Unfortunately (at this time) there is no easy way to launch this view from the command line — SourceTree's CLI currently just opens repos.

The proper way to do with would be to use the v-el directive to give it a reference. Then you can do this.$$[reference].

Update for vue 2

In Vue 2 refs are used for both elements and components: http://vuejs.org/guide/migration.html#v-el-and-v-ref-replaced

The best way for spell checking in python is by: SymSpell, Bk-Tree or Peter Novig's method.

The fastest one is SymSpell.

This is Method1: Reference link pyspellchecker

This library is based on Peter Norvig's implementation.

pip install pyspellchecker

from spellchecker import SpellChecker

spell = SpellChecker()

# find those words that may be misspelled
misspelled = spell.unknown(['something', 'is', 'hapenning', 'here'])

for word in misspelled:
    # Get the one `most likely` answer
    print(spell.correction(word))

    # Get a list of `likely` options
    print(spell.candidates(word))

Method2: SymSpell Python

pip install -U symspellpy

You can use a higher-level function like:

file_put_contents($filename, $content);

which is identical to calling fopen(), fwrite(), and fclose() successively to write data to a file.

Docs: file_put_contents

For me this code worked best:

private func getCoordinate(_ view: UIView) -> CGPoint {
    var x = view.frame.origin.x
    var y = view.frame.origin.y
    var oldView = view

    while let superView = oldView.superview {
        x += superView.frame.origin.x
        y += superView.frame.origin.y
        if superView.next is UIViewController {
            break //superView is the rootView of a UIViewController
        }
        oldView = superView
    }

    return CGPoint(x: x, y: y)
}

After digging into hibernate source code and Below configuration goes to Oracle db for the next value after 50 inserts. So make your INST_PK_SEQ increment 50 each time it is called.

Hibernate 5 is used for below strategy

Check also below http://docs.jboss.org/hibernate/orm/5.1/userguide/html_single/Hibernate_User_Guide.html#identifiers-generators-sequence

@Id
@Column(name = "ID")
@GenericGenerator(name = "INST_PK_SEQ", 
strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
parameters = {
        @org.hibernate.annotations.Parameter(
                name = "optimizer", value = "pooled-lo"),
        @org.hibernate.annotations.Parameter(
                name = "initial_value", value = "1"),
        @org.hibernate.annotations.Parameter(
                name = "increment_size", value = "50"),
        @org.hibernate.annotations.Parameter(
                name = SequenceStyleGenerator.SEQUENCE_PARAM, value = "INST_PK_SEQ"),
    }
)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "INST_PK_SEQ")
private Long id;

Entity Framework performs something similar to gbn's answer:

DECLARE @generated_keys table([Id] uniqueidentifier)

INSERT INTO Customers(FirstName)
OUTPUT inserted.CustomerID INTO @generated_keys
VALUES('bob');

SELECT t.[CustomerID]
FROM @generated_keys AS g 
   JOIN dbo.Customers AS t 
   ON g.Id = t.CustomerID
WHERE @@ROWCOUNT > 0

The output results are stored in a temporary table variable, and then selected back to the client. Have to be aware of the gotcha:

inserts can generate more than one row, so the variable can hold more than one row, so you can be returned more than one ID

I have no idea why EF would inner join the ephemeral table back to the real table (under what circumstances would the two not match).

But that's what EF does.

SQL Server 2008 or newer only. If it's 2005 then you're out of luck.

select *
into existing table database..existingtable
from database..othertables....

If you have used select * into tablename from other tablenames already, next time, to append, you say select * into existing table tablename from other tablenames

I don't know how to delete all at once, but you can use ipcs to list resources, and then use loop and delete with ipcrm. This should work, but it needs a little work. I remember that I made it work once in class.

To bind any data,which sends service is not a good idea (architecture),but if you need it anymore I suggest you 2 ways to do that

1) you can get the data not inside you service.You can get data inside your controller/directive and you will not have a problem to bind it anywhere

2) you can use angularjs events.Whenever you want,you can send a signal(from $rootScope) and catch it wherever you want.You can even send a data on that eventName.

Maybe this can help you. If you need more with examples,here is the link

http://www.w3docs.com/snippets/angularjs/bind-value-between-service-and-controller-directive.html

This approach worked for me:

• Close VS2015
• Open the solution temporarily in VS2013 and enable nuget package restore by right clicking on the solution (i also did a rebuild, but I suspect that is not needed).
• Close VS2013
• Reopen the solution in VS2015

You have now enabled nuget package restore in VS2015 as well.

This is an old posting but maybe still useful for someone.

I had the same error message. In the end the problem was an invalid name for the second argument, i.e., I had a line like:

   window.open('/somefile.html', 'a window title', 'width=300');

The problem was 'a window title' as it is not valid. It worked fine with the following line:

   window.open('/somefile.html', '', 'width=300');

In fact, reading carefully I realized that Microsoft does not support a name as second argument. When you look at the official documentation page, you see that Microsoft only allows the following arguments, If using that argument at all:

• _blank
• _media
• _parent
• _search
• _self
• _top

BST a kind of binary tree is used in Unix kernels for managing a set of virtual memory areas(VMAs).

I had similar issue. However, I was able to fix it when I updated my iPad timings to that of current. I just checked the device log and found that the time in the log was shown 2 years before.

Hope updating the device timing to the current time will fix the issue.

Click on "Connect as" and select "specific user", then type in the credentials of your user (I used the admin of the server).

Can confirm that leaving px out from width and height did the trick for Outlook

Place the function value into the cell

Application.Sum often does not work well in my experience (or at least the VBA developer environment does not like it for whatever reason).

The function that works best for me is Excel.WorksheetFunction.Sum()

Example:

Dim Report As Worksheet 'Set up your new worksheet variable.
Set Report = Excel.ActiveSheet 'Assign the active sheet to the variable.

Report.Cells(11, 1).Value = Excel.WorksheetFunction.Sum(Report.Range("A1:A10")) 'Add the function result.

Place the function directly into the cell

The other method which you were looking for I think is to place the function directly into the cell. This can be done by inputting the function string into the cell value. Here is an example that provides the same result as above, except the cell value is given the function and not the result of the function:

    Dim Report As Worksheet 'Set up your new worksheet variable.
    Set Report = Excel.ActiveSheet 'Assign the active sheet to the variable.

    Report.Cells(11, 1).Value = "=Sum(A1:A10)" 'Add the function.

Here is the extension method to load an image from URI:

public static BitmapImage GetBitmapImage(
    this Uri imageAbsolutePath,
    BitmapCacheOption bitmapCacheOption = BitmapCacheOption.Default)
{
    BitmapImage image = new BitmapImage();
    image.BeginInit();
    image.CacheOption = bitmapCacheOption;
    image.UriSource = imageAbsolutePath;
    image.EndInit();

    return image;
}

Sample of use:

Uri _imageUri = new Uri(imageAbsolutePath);
ImageXamlElement.Source = _imageUri.GetBitmapImage(BitmapCacheOption.OnLoad);

Simple as that!

bool is just a macro that expands to _Bool. You can use _Bool with no #include very much like you can use int or double; it is a C99 keyword.

The macro is defined in <stdbool.h> along with 3 other macros.

The macros defined are

• bool: macro expands to _Bool
• false: macro expands to 0
• true: macro expands to 1
• __bool_true_false_are_defined: macro expands to 1

Decoding is redundant

You only had this "error" in the first place, because of a misunderstanding of what's happening.

You get the b because you encoded to utf-8 and now it's a bytes object.

 >> type("text".encode("utf-8"))
 >> <class 'bytes'>

Fixes:

1. You can just print the string first
2. Redundantly decode it after encoding

There is %history magic for printing and saving the input history (and optionally the output).

To store your current session to a file named my_history.py:

>>> %hist -f my_history.py

History IPython stores both the commands you enter, and the results it produces. You can easily go through previous commands with the up- and down-arrow keys, or access your history in more sophisticated ways.

You can use the %history magic function to examine past input and output. Input history from previous sessions is saved in a database, and IPython can be configured to save output history.

Several other magic functions can use your input history, including %edit, %rerun, %recall, %macro, %save and %pastebin. You can use a standard format to refer to lines:

%pastebin 3 18-20 ~1/1-5

This will take line 3 and lines 18 to 20 from the current session, and lines 1-5 from the previous session.

See %history? for the Docstring and more examples.

Also, be sure to explore the capabilities of %store magic for lightweight persistence of variables in IPython.

Stores variables, aliases and macros in IPython’s database.

d = {'a': 1, 'b': 2}
%store d  # stores the variable
del d

%store -r d  # Refresh the variable from IPython's database.
>>> d
{'a': 1, 'b': 2}

To autorestore stored variables on startup, specifyc.StoreMagic.autorestore = True in ipython_config.py.

You can attach a SLOT to the

void aboutToQuit();

signal of your QApplication. This signal should be raised just before app closes.

First you have to know what is a determinant? the determinant is an attribute that used to determine another attribute in the same table. SO the determinant must be a candidate key. And you can have more than one determinant. But primary key is used to determine the whole record and you can have only one primary key. Both primary and candidate key can consist of one or more attributes

rvm --default use 2.2.4

Run the command INFO. The version will be the first item displayed.

The advantage of this over redis-server --version is that sometimes you don't have access to the server (e.g. when it's provided to you on the cloud), in which case INFO is your only option.

Disclaimer: I've written fast-xml-parser

Fast XML Parser can help to convert XML to JSON and vice versa. Here is the example;

var options = {
    attributeNamePrefix : "@_",
    attrNodeName: "attr", //default is 'false'
    textNodeName : "#text",
    ignoreAttributes : true,
    ignoreNameSpace : false,
    allowBooleanAttributes : false,
    parseNodeValue : true,
    parseAttributeValue : false,
    trimValues: true,
    decodeHTMLchar: false,
    cdataTagName: "__cdata", //default is 'false'
    cdataPositionChar: "\\c",
};
if(parser.validate(xmlData)=== true){//optional
    var jsonObj = parser.parse(xmlData,options);
}

If you want to parse JSON or JS object into XML then

//default options need not to set
var defaultOptions = {
    attributeNamePrefix : "@_",
    attrNodeName: "@", //default is false
    textNodeName : "#text",
    ignoreAttributes : true,
    encodeHTMLchar: false,
    cdataTagName: "__cdata", //default is false
    cdataPositionChar: "\\c",
    format: false, 
    indentBy: "  ",
    supressEmptyNode: false
};
var parser = new parser.j2xParser(defaultOptions);
var xml = parser.parse(json_or_js_obj);

I think you are a bit confused. You should read a good tutorial/book on pointers.

This tutorial is very good for starters(clearly explains what & and * are). And yeah don't forget to read the book Pointers in C by Kenneth Reek.

The difference between & and * is very clear.

Example:

#include <stdio.h>

int main(){
  int x, *p;

  p = &x;         /* initialise pointer(take the address of x) */
  *p = 0;         /* set x to zero */
  printf("x is %d\n", x);
  printf("*p is %d\n", *p);

  *p += 1;        /* increment what p points to i.e x */
  printf("x is %d\n", x);

  (*p)++;         /* increment what p points to i.e x */
  printf("x is %d\n", x);

  return 0;
}

If you want to display date time on view without model, just write this:

Date : @DateTime.Now

The output will be:

Date : 16-Aug-17 2:32:10 PM

I just input some value that I knew was invalid and here is the output:

'whatToInput' is not a supported event for HtmlPanelGrid. Please specify one of these supported event names: click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup.

So values you can pass to event are

• click
• dblclick
• keydown
• mousedown
• mousemove
• mouseover
• mouseup

So when sending the message to telegram you use:

$token = <Enter Your Token Here>
$url = "https://api.telegram.org/bot".$token;

$chat_id = <The Chat Id Goes Here>;
$test = <Message goes Here>;

//sending Message normally without styling
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text");

If our message has html tags in it we add "parse_mode" so that our url becomes:

$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text&parse_mode=html")

parse mode can be "HTML" or "markdown"

$('.page-address-edit').addClass('test1 test2 test3');

Remove basically works on the value . Delete and pop work on the index

Remove basically removes the first matching value. Delete deletes the item from a specific index Pop basically takes an index and returns the value at that index. Next time you print the list the value doesnt appear.

If the user successful login into your Node app, I'm thinking that you are using Express, isn't ? Well you can redirect easy by using res.redirect. Like:

app.post('/auth', function(req, res) {
  // Your logic and then redirect
  res.redirect('/user_profile');
});

W3Schools have a nice article on this subject.

Scripts in <head>

Scripts to be executed when they are called, or when an event is triggered, are placed in functions.

Put your functions in the head section, this way they are all in one place, and they do not interfere with page content.

Scripts in <body>

If you don't want your script to be placed inside a function, or if your script should write page content, it should be placed in the body section.

As of .NET 5 RC2 you can use:

• Convert.ToHexString(byte[] inArray) which returns a string and
• Convert.FromHexString(string s) which returns a byte[].

Overloads are available that take span parameters.

GOOGLEFINANCE can have a 20 minutes delay, so refreshing every minute would not really help.

Instead of GOOGLEFINANCE you can use different source. I'm using this RealTime stock prices(I tried a couple but this is the easiest by-far to implement. They have API that retuen JSON { Name: CurrentPrice }

Here's a little script you can use in Google Sheets(Tools->Script Editor)

function GetStocksPrice() {      
   var url = 'https://financialmodelingprep.com/api/v3/stock/real-time- 
   price/AVP,BAC,CHK,CY,GE,GPRO,HIMX,IMGN,MFG,NIO,NMR,SSSS,UCTT,UMC,ZNGA';
   var response = UrlFetchApp.fetch(url);

   // convert json string to json object
   var jsonSignal = JSON.parse(response);    

  // define an array of all the object keys
  var headerRow = Object.keys(jsonSignal);
  // define an array of all the object values
  var values = headerRow.map(function(key){ return jsonSignal[key]});   
  var data = values[0];

  // get sheet by ID -  
  // you can get the sheet unqiue ID from the your current sheet url
  var jsonSheet = SpreadsheetApp.openById("Your Sheet UniqueID");  
  //var name = jsonSheet.getName();

  var sheet = jsonSheet.getSheetByName('Sheet1'); 

  // the column to put the data in -> Y
  var letter = "F";

  // start from line 
  var index = 4;
  data.forEach(function( row, index2 ) { 

     var keys = Object.keys(row);
     var value2 = row[keys[1]];            

     // set value loction
     var cellXY = letter +  index;      
     sheet.getRange(cellXY).setValue(value2);  
  
     index = index + 1;    
 });  
}

Now you need to add a trigger that will execute every minute.

1. Go to Project Triggers -> click on the Watch icon next to the Save icon
2. Add Trigger
3. In -> Choose which function to run -> GetStocksPrice
4. In -> Select event source -> Time-driven
5. In -> Select type of time based trigger -> Minutes timer
6. In -> Select minute interval -> Every minute

And your set :)

Take a look at the fields's proprieties (type, length, default value, etc.), they should be the same.

I had this problem with SQL Server 2008 R2 because the fields's length are not equal.

Mod-rewrite based solution :

Using the following code in htaccess automatically forwards all http requests to https.

RewriteEngine on

RewriteCond %{HTTPS}::%{HTTP_HOST} ^off::(?:www\.)?(.+)$
RewriteRule ^ https://www.%1%{REQUEST_URI} [NE,L,R]

This will redirect your non-www and www http requests to www version of https.

Another solution (Apache 2.4*)

RewriteEngine on

RewriteCond %{REQUEST_SCHEME}::%{HTTP_HOST} ^http::(?:www\.)?(.+)$
RewriteRule ^ https://www.%1%{REQUEST_URI} [NE,L,R]

This doesn't work on lower versions of apache as %{REQUEST_SCHEME} variable was added to mod-rewrite since 2.4.

REST is not necessarily tied to HTTP. RESTful web services are just web services that follow a RESTful architecture.

What is Rest -
1- Client-server
2- Stateless
3- Cacheable
4- Layered system
5- Code on demand
6- Uniform interface

To write a newline use \n not /n the latter is just a slash and a n

A simpler way is to transverse the data, and hide the lines with the Visible property.

// Prevent exception when hiding rows out of view
CurrencyManager currencyManager = (CurrencyManager)BindingContext[dataGridView3.DataSource];
currencyManager.SuspendBinding();

// Show all lines
for (int u = 0; u < dataGridView3.RowCount; u++)
{
    dataGridView3.Rows[u].Visible = true;
    x++;
}

// Hide the ones that you want with the filter you want.
for (int u = 0; u < dataGridView3.RowCount; u++)
{
    if (dataGridView3.Rows[u].Cells[4].Value == "The filter string")
    {
        dataGridView3.Rows[u].Visible = true;
    }
    else
    {
        dataGridView3.Rows[u].Visible = false;
    }
}

// Resume data grid view binding
currencyManager.ResumeBinding();

Just an idea... it works for me.

As of now, with Revision 26.1.3 of the android emulator, it is finally possible on the image v8 of the API 25. If the emulator was created before you upgrade to the latest API 25 image, you need to wipe data or simply delete and recreate your image if you prefer.

Added support for Wi-Fi in some system images (currently only API level 25). An access point called "AndroidWifi" is available and Android automatically connects to it. Wi-Fi support can be disabled by running the emulator with the command line parameter -feature -Wifi.

You aren't really using the doGet() method. When you're opening the page, it issues a GET request, not POST.

Try changing doPost() to service() instead... then you're using the same method to handle GET and POST requests.

...

get returns Collection and is rather supposed to fetch multiple rows.

count is a generic way of checking the result:

$user = User::where(...)->first(); // returns Model or null
if (count($user)) // do what you want with $user

// or use this:
$user = User::where(...)->firstOrFail(); // returns Model or throws ModelNotFoundException

// count will works with a collection of course:
$users = User::where(...)->get(); // returns Collection always (might be empty)
if (count($users)) // do what you want with $users

One must keep in mind the nature of git. You have remotes and your local branches ( not necessarily the same ) . In comparison to other source control systems this can be a bit perplexing.

Usually when you checkout a remote a local copy is created that tracks the remote.

git fetch will work with the remote branch and update your information.

It is actually the case if other SWEs are working one the same branch, and rarely the case in small one dev - one branch - one project scenarios.

Your work on the local branch is still intact. In order to bring the changes to your local branch you have to merge/rebase the changes from the remote branch.

git pull does exactly these two steps ( i.e. --rebase to rebase instead of merge )

If your local history and the remote history have conflicts the you will be forced to do the merge during a git push to publish your changes.

Thus it really depends on the nature of your work environment and experience what to use.

In this particular case, an even simpler fix would be to just get rid of the "+" all together because AGE is a string literal and what comes before and after are also string literals. You could write line 3 as:

str += "Do you feel " AGE " years old?";

This is because most C/C++ compilers will concatenate string literals automatically. The above is equivalent to:

str += "Do you feel " "42" " years old?";

which the compiler will convert to:

str += "Do you feel 42 years old?";

your syntax is completely wrong....you need to give findelement to the driver

i.e your code will be :

WebDriver driver = new FirefoxDriver();
WebeElement element ;

element = driver.findElement(By.xpath("//[@test-id='test-username']"); 

// your xpath is: "//[@test-id='test-username']"

i suggest try this :"//*[@test-id='test-username']"

I tried this on Laravel 4.2

Rename the server.php in the your Laravel root folder to index.php and copy the .htaccess file from /public directory to your Laravel root folder.

I hope it works

You want to look at the patch() function, and sneak in points for the start and end of the horizontal line:

x = 0:.1:2*pi;
y = sin(x)+rand(size(x))/2;

x2 = [0 x 2*pi];
y2 = [.1 y .1];
patch(x2, y2, [.8 .8 .1]);

If you only want the filled in area for a part of the data, you'll need to truncate the x and y vectors to only include the points you need.

I did Anagram excersize, which is like Count Change problem but with 50 000 denominations (coins). I am not sure that it can be done iteratively, I do not care. I just know that the -xss option had no effect -- I always failed after 1024 stack frames (might be scala does bad job delivering to to java or printStackTrace limitation. I do not know). This is bad option, as explained anyway. You do not want all threads in to app to be monstrous. However, I did some experiments with new Thread (stack size). This works indeed,

  def measureStackDepth(ss: Long): Long = {
    var depth: Long = 0
      val thread: Thread = new Thread(null, new Runnable() {
        override def run() {
          try {
          def sum(n: Long): Long = {depth += 1; if (n== 0) 0 else sum(n-1) + 1}
          println("fact = " + sum(ss * 10))
          } catch {
            case e: StackOverflowError => // eat the exception, that is expected
          }
        }
      }, "deep stack for money exchange", ss)
      thread.start()
      thread.join()
    depth
  }                                               //> measureStackDepth: (ss: Long)Long


  for (ss <- (0 to 10)) println("ss = 10^" +  ss + " allows stack of size " -> measureStackDepth((scala.math.pow (10, ss)).toLong) )
                                                  //> fact = 10
                                                  //| (ss = 10^0 allows stack of size ,11)
                                                  //| fact = 100
                                                  //| (ss = 10^1 allows stack of size ,101)
                                                  //| fact = 1000
                                                  //| (ss = 10^2 allows stack of size ,1001)
                                                  //| fact = 10000
                                                  //| (ss = 10^3 allows stack of size ,10001)
                                                  //| (ss = 10^4 allows stack of size ,1336)
                                                  //| (ss = 10^5 allows stack of size ,5456)
                                                  //| (ss = 10^6 allows stack of size ,62736)
                                                  //| (ss = 10^7 allows stack of size ,623876)
                                                  //| (ss = 10^8 allows stack of size ,6247732)
                                                  //| (ss = 10^9 allows stack of size ,62498160)

You see that stack can grow exponentially deeper with exponentially more stack alloted to the thread.

This is what I did

//Array of numbers
var numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10,32,23,643,67,5876,6345,34,3453];
//Array of even numbers
var evenNumbers = [];
//Array of odd numbers
var oddNumbers = [];

function classifyNumbers(arr){
  //go through the numbers one by one
  for(var i=0; i<=arr.length-1; i++){
     if (arr[i] % 2 == 0 ){
        //Push the number to the evenNumbers array
        evenNumbers.push(arr[i]);
     } else {
        //Push the number to the oddNumbers array
        oddNumbers.push(arr[i]);
     }
  }
}

classifyNumbers(numbers);

console.log('Even numbers: ' + evenNumbers);
console.log('Odd numbers: ' + oddNumbers);

For some reason I had to make sure the length of the array is less by one. When I don't do that, I get "undefined" in the last element of the oddNumbers array.

If you are crashing than you probably need [weak self]

My guess is that the block you are creating is somehow still wired up.

Create a prepareForReuse and try clearing the onTextViewEditClosure block inside that.

func prepareForResuse() {
   onTextViewEditClosure = nil
   textView.delegate = nil
}

See if that prevents the crash. (It's just a guess).

Try using String.getBytes(). It returns a byte[] representing string data. Example:

String data = "sample data";
byte[] byteData = data.getBytes();

No need for jquery here, just a for loop works:

var substr = currnt_image_list.split(',');
for(var i=0; i< substr.length; i++) {
  alert(substr[i]);
}

In addition to the intuitive explanation Chris Smith has provided, we can consider why this is the case from a different perspective: considering undirected graphs.

To see why in a DIRECTED graph the answer is n*(n-1), consider an undirected graph (which simply means that if there is a link between two nodes (A and B) then you can go in both ways: from A to B and from B to A). The maximum number of edges in an undirected graph is n(n-1)/2 and obviously in a directed graph there are twice as many.

Good, you might ask, but why are there a maximum of n(n-1)/2 edges in an undirected graph? For that, Consider n points (nodes) and ask how many edges can one make from the first point. Obviously, n-1 edges. Now how many edges can one draw from the second point, given that you connected the first point? Since the first and the second point are already connected, there are n-2 edges that can be done. And so on. So the sum of all edges is:

Sum = (n-1)+(n-2)+(n-3)+...+3+2+1 

Since there are (n-1) terms in the Sum, and the average of Sum in such a series is ((n-1)+1)/2 {(last + first)/2}, Sum = n(n-1)/2

Found my answer and adding it here in case it helps David (and others).

Turns out my origin server (say www.example.com) had a 301 redirect setup on it to change HTTP to HTTPS:

HTTP/1.1 301 Moved Permanently
Location: https://www.example.com/images/Foo_01.jpg

However, my Origin Protocol Policy was set to HTTP only. This caused CloudFront to not find my file and throw a 502 error. Additionally, I think it cached the 502 error for 5 min or so as it didn't work immediately after removing that 301 redirect.

Hope that helps!

I think this is slightly more readable. It uses Array.from and logic is identical to using nested loops:

var arr = [_x000D_
  [1, 2, 3, 4],_x000D_
  [1, 2, 3, 4],_x000D_
  [1, 2, 3, 4]_x000D_
];_x000D_
_x000D_
/*_x000D_
 * arr[0].length = 4 = number of result rows_x000D_
 * arr.length = 3 = number of result cols_x000D_
 */_x000D_
_x000D_
var result = Array.from({ length: arr[0].length }, function(x, row) {_x000D_
  return Array.from({ length: arr.length }, function(x, col) {_x000D_
    return arr[col][row];_x000D_
  });_x000D_
});_x000D_
_x000D_
console.log(result);

If you are dealing with arrays of unequal length you need to replace arr[0].length with something else:

var arr = [_x000D_
  [1, 2],_x000D_
  [1, 2, 3],_x000D_
  [1, 2, 3, 4]_x000D_
];_x000D_
_x000D_
/*_x000D_
 * arr[0].length = 4 = number of result rows_x000D_
 * arr.length = 3 = number of result cols_x000D_
 */_x000D_
_x000D_
var result = Array.from({ length: arr.reduce(function(max, item) { return item.length > max ? item.length : max; }, 0) }, function(x, row) {_x000D_
  return Array.from({ length: arr.length }, function(x, col) {_x000D_
    return arr[col][row];_x000D_
  });_x000D_
});_x000D_
_x000D_
console.log(result);

read without any parameters will only continue if you press enter. The DOS pause command will continue if you press any key. Use read –n1 if you want this behaviour.

You should never apply bindings more than once to a view. In 2.2, the behaviour was undefined, but still unsupported. In 2.3, it now correctly shows an error. When using knockout, the goal is to apply bindings once to your view(s) on the page, then use changes to observables on your viewmodel to change the appearance and behaviour of your view(s) on your page.

I know this question is pretty old but just want to share my findings.

My laptop is able to handle program which spawns 25,000 threads and all those threads write some data in MySql database at regular interval of 2 seconds.

I ran this program with 10,000 threads for 30 minutes continuously then also my system was stable and I was able to do other normal operations like browsing, opening, closing other programs, etc.

With 25,000 threads system slows down but it remains responsive.

With 50,000 threads system stopped responding instantly and I had to restart my system manually.

My system details are as follows :

Processor : Intel core 2 duo 2.13 GHz
RAM : 4GB
OS : Windows 7 Home Premium
JDK Version : 1.6

Before running I set jvm argument -Xmx2048m.

Hope it helps.

I had the same problem and I could solve it by adding the entity into persistence.xml. The problem was caused due to the fact that the entity was not added to the persistence config. Edit your persistence file:

<persistence-unit name="MY_PU" transaction-type="RESOURCE_LOCAL">
<provider>`enter code here`
     org.hibernate.jpa.HibernatePersistenceProvider
  </provider>
<class>mypackage.MyEntity</class>

...

Make sure you have all the required dependencies, go to the url xxx/swagger/v1/swagger.json you might find that you're missing one or more dependencies.

xDoc.LoadXML("<head><body><Inner> welcome </head> </Inner> <Outer> Bye</Outer>                    
                    </body></head>");

You can alias the column names one by one, like so

SELECT col1 as `MyNameForCol1`, col2 as `MyNameForCol2` 
FROM `foobar`

Edit You can access INFORMATION_SCHEMA.COLUMNS directly to mangle a new alias like so. However, how you fit this into a query is beyond my MySql skills :(

select CONCAT('Foobar_', COLUMN_NAME)
from INFORMATION_SCHEMA.COLUMNS 
where TABLE_NAME = 'Foobar'

var newA = document.createElement('a');
newA.setAttribute('href',"http://localhost");
newA.innerHTML = "link text";
document.appendChild(newA);

One more for the road that's a bit more flexible for matching specific filenames because it uses wildcard globbing. In a functional style this could resemble:

import java.io.IOException;
import java.net.URISyntaxException;
import java.nio.file.FileSystem;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.function.Consumer;

import static java.nio.file.FileSystems.getDefault;
import static java.nio.file.FileSystems.newFileSystem;
import static java.util.Collections.emptyMap;

/**
 * Responsible for finding file resources.
 */
public class ResourceWalker {
  /**
   * Globbing pattern to match font names.
   */
  public static final String GLOB_FONTS = "**.{ttf,otf}";

  /**
   * @param directory The root directory to scan for files matching the glob.
   * @param c         The consumer function to call for each matching path
   *                  found.
   * @throws URISyntaxException Could not convert the resource to a URI.
   * @throws IOException        Could not walk the tree.
   */
  public static void walk(
    final String directory, final String glob, final Consumer<Path> c )
    throws URISyntaxException, IOException {
    final var resource = ResourceWalker.class.getResource( directory );
    final var matcher = getDefault().getPathMatcher( "glob:" + glob );

    if( resource != null ) {
      final var uri = resource.toURI();
      final Path path;
      FileSystem fs = null;

      if( "jar".equals( uri.getScheme() ) ) {
        fs = newFileSystem( uri, emptyMap() );
        path = fs.getPath( directory );
      }
      else {
        path = Paths.get( uri );
      }

      try( final var walk = Files.walk( path, 10 ) ) {
        for( final var it = walk.iterator(); it.hasNext(); ) {
          final Path p = it.next();
          if( matcher.matches( p ) ) {
            c.accept( p );
          }
        }
      } finally {
        if( fs != null ) { fs.close(); }
      }
    }
  }
}

Consider parameterizing the file extensions, left an exercise for the reader.

Be careful with Files.walk. According to the documentation:

This method must be used within a try-with-resources statement or similar control structure to ensure that the stream's open directories are closed promptly after the stream's operations have completed.

Likewise, newFileSystem must be closed, but not before the walker has had a chance to visit the file system paths.

You don't need preg_* functions nor preg patterns nor str_replace within, etc .. in order to sucessfuly break a string into array by newlines. In all scenarios, be it Linux/Mac or m$, this will do.

<?php 

 $array = explode(PHP_EOL, $string);
 // ...  
 $string = implode(PHP_EOL, $array);

?>

PHP_EOL is a constant holding the line break character(s) used by the server platform.

Since there's no mention of how to compile a .c file together with a bunch of .o files, and this comment asks for it:

where's the main.c in this answer? :/ if file1.c is the main, how do you link it with other already compiled .o files? – Tom Brito Oct 12 '14 at 19:45

$ gcc main.c lib_obj1.o lib_obj2.o lib_objN.o -o x0rbin

Here, main.c is the C file with the main() function and the object files (*.o) are precompiled. GCC knows how to handle these together, and invokes the linker accordingly and results in a final executable, which in our case is x0rbin.

You will be able to use functions not defined in the main.c but using an extern reference to functions defined in the object files (*.o).

You can also link with .obj or other extensions if the object files have the correct format (such as COFF).

If you are trying to load a file which is not in the same directory as your Java class, you've got to use the runtime directory structure rather than the one which appears at design time.

To find out what the runtime directory structure is, check your {root project dir}/target/classes directory. This directory is accessible via the "." URL.

Based on user4284592's answer, the following worked for me:

ClassLoader cl = getClass().getClassLoader();
File file = new File(cl.getResource("./docs/doc.pdf").getFile());

with the following directory structure:

{root dir}/target/classes/docs/doc.pdf

Here's an explanation, so you don't just blindly copy and paste my code:

• java.lang.ClassLoader is an object that is responsible for loading classes. Every Class object contains a reference to the ClassLoader that defined it and can fetch it with getClassLoader() method.
• ClassLoader's getResource method finds the resource with the given name. A resource is some data that can be accessed by class code in a way that is independent of the location of the code.

To add to the other answers, I think the acronyms were derived to show a scale between the two terms to distinguish how reliable transactions or requests where between RDMS versus Big Data.

From this article acid vs base

In Chemistry, pH measures the relative basicity and acidity of an aqueous (solvent in water) solution. The pH scale extends from 0 (highly acidic substances such as battery acid) to 14 (highly alkaline substances like lie); pure water at 77° F (25° C) has a pH of 7 and is neutral.

Data engineers have cleverly borrowed acid vs base from chemists and created acronyms that while not exact in their meanings, are still apt representations of what is happening within a given database system when discussing the reliability of transaction processing.

One other point, since I work with Big Data using Elasticsearch. To clarify, an instance of Elasticsearch is a node and a group of nodes form a cluster.

To me from a practical standpoint, BA (Basically Available), in this context, has the idea of multiple master nodes to handle the Elasticsearch cluster and it's operations.

If you have 3 master nodes and the currently directing master node goes down, the system stays up, albeit in a less efficient state, and another master node takes its place as the main directing master node. If two master nodes go down, the system still stays up and the last master node takes over.

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

The whole slide deck is quite interesting. The presentation is available on YouTube, but it doesn't add much to the slides.

Also when I hit the post(Config.getURL("login"), values) the app seems to pause for a while (seems weird - thought the idea behind a service was that it runs on a different thread!)

In this case its better to use asynctask, which runs on a different thread and return result back to the ui thread on completion.

As pointed out by an answer above, you can use javax.ws.rs.core.MediaType which has the required constants.

I also wanted to share a really cool and handy link which I found that gives a reference to all the Javax constants in one place - https://docs.oracle.com/javaee/7/api/constant-values.html.

I was able to accomplish this using a FormArray of FormGroups. The FormGroup consists of two controls. One for the data and one to store the checked boolean.

TS

options: options[] = [{id: 1, text: option1}, {id: 2, text: option2}];

this.fb.group({
  options: this.fb.array([])
})    

populateFormArray() {    
  this.options.forEach(option => {                       
    let checked = ***is checked logic here***;            
    this.checkboxGroup.get('options').push(this.createOptionGroup(option, checked))
  });       
}  

createOptionGroup(option: Option, checked: boolean) {
  return this.fb.group({      
    option: this.fb.control(option),
    checked: this.fb.control(checked)
  });
}

HTML

This allows you to loop through the options and bind to the corresponding checked control.

<form [formGroup]="checkboxGroup">
  <div formArrayName="options" *ngFor="let option of options; index as i">   
    <div [formGroupName]="i">
      <input type="checkbox" formControlName="checked" />
      {{ option.text }}
    </div>
  </div>       
</form>

Output

The form returns data in the form {option: Option, checked: boolean}[].

You can get a list of checked options using the below code

 this.checkboxGroup.get('options').value.filter(el => el.checked).map(el => el.option);

I have had the same problem as noted above. I could not get Eclipse to install because of Java incompatibilities. The sequence I followed goes like this:

1. Upgraded to MAC OS Sierra
2. Downloaded the Eclipse installer but was prompted that I needed to instal a legacy Java.
3. Installed Java 1.6
4. Was unable to install Eclipse and was prompted that I needed Java 1.7 or greater. Downloaded and installed Java 1.8
5. Ran the terminal code 'java -version' // this will check your jre version. This showed returned Java 1.6 despite the fact that I had upgraded to 1.8. The Java version listed in the Java control panel said 1.8
6. Tried multiple downloads of eclipse and Java and multiple restarts always with the same result.
7. Visited the Oracle web page noted above: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html I could not find the above reference to 8u73 and 8u74 but I did find and option to download 1.8.0_12. I did this. It installed without difficulty, and then I was able to install Eclipse without difficulty.

This took hours of my time. I hope this proves useful.

To convert an integer to a string:

integer :: i    
character* :: s    
if (i.LE.9) then
     s=char(48+i)    
else if (i.GE.10) then
     s=char(48+(i/10))// char(48-10*(i/10)+i)    
endif

just add

android:gravity="center"

and done :)

you need to take out the quotes:

soda = a + b

(You want to refer to the variables a and b, not the strings "a" and "b")

Multiple columns in a key are going to, in general, perform more poorly than a surrogate key. I prefer to have a surrogate key and then a unique index on a multicolumn key. That way you can have better performance and the uniqueness needed is maintained. And even better, when one of the values in that key changes, you don't also have to update a million child entries in 215 child tables.

That answer points to this article: http://support.microsoft.com/kb/918760

Here are the proposed solutions - have you evaluated them?

• Method 1: Use a SQL Server Agent proxy account

Create a SQL Server Agent proxy account. This proxy account must use a credential that lets SQL Server Agent run the job as the account that created the package or as an account that has the required permissions.

This method works to decrypt secrets and satisfies the key requirements by user. However, this method may have limited success because the SSIS package user keys involve the current user and the current computer. Therefore, if you move the package to another computer, this method may still fail, even if the job step uses the correct proxy account. Back to the top

• Method 2: Set the SSIS Package ProtectionLevel property to ServerStorage

Change the SSIS Package ProtectionLevel property to ServerStorage. This setting stores the package in a SQL Server database and allows access control through SQL Server database roles. Back to the top

• Method 3: Set the SSIS Package ProtectionLevel property to EncryptSensitiveWithPassword

Change the SSIS Package ProtectionLevel property to EncryptSensitiveWithPassword. This setting uses a password for encryption. You can then modify the SQL Server Agent job step command line to include this password.

• Method 4: Use SSIS Package configuration files

Use SSIS Package configuration files to store sensitive information, and then store these configuration files in a secured folder. You can then change the ProtectionLevel property to DontSaveSensitive so that the package is not encrypted and does not try to save secrets to the package. When you run the SSIS package, the required information is loaded from the configuration file. Make sure that the configuration files are adequately protected if they contain sensitive information.

• Method 5: Create a package template

For a long-term resolution, create a package template that uses a protection level that differs from the default setting. This problem will not occur in future packages.

I would like to add that you can extend the compatibility of :scope by just assigning a temporary attribute to the current node.

let node = [...];
let result;

node.setAttribute("foo", "");
result = window.document.querySelectorAll("[foo] > .bar");
// And, of course, you can also use other combinators.
result = window.document.querySelectorAll("[foo] + .bar");
result = window.document.querySelectorAll("[foo] ~ .bar");
node.removeAttribute("foo");

Try this

plt.imshow(im.reshape(im.shape[0], im.shape[1]), cmap=plt.cm.Greys)

It would help in some cases.

I updated my Gradle 2.3.3 to 4.4 and got an error on AppCompatActivity and also Cardview. I tried with clean project and rebuild project. It won't work, then I go to Project Folder -> .idea -> create backup of libraries folder and remove it -> then Rebuild Project that solved my issue.

Not sure whether it would help you or not but it works to me:

l = ["a", "b", "c", "d", "e"]
outRes = dict((l[i], l[i+1]) if i+1 < len(l) else (l[i], '') for i in xrange(len(l)))

A more general approach that will attempt to check for both integers and integers given as strings will be

def isInt(anyNumberOrString):
    try:
        int(anyNumberOrString) #to check float and int use "float(anyNumberOrString)"
        return True
    except ValueError :
        return False

isInt("A") #False
isInt("5") #True
isInt(8) #True
isInt("5.88") #False *see comment above on how to make this True

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

Here's a version that doesn't fail if log.txt is missing:

@echo off
  if not exist log.txt goto firstlogin
  echo Date/Time last login:
  type log.txt
  goto end

:firstlogin
  echo No last login found.

:end
  echo %date%, %time%. > log.txt
  pause

the ideal way is to

{{ something|safe }}

than completely turning off auto escaping.

Why not use a Single liner ...

IEnumerable<Book> _Book_IE= _Book_List as IEnumerable<Book>;

Add both of those for the theme you use:

    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>

SELECT * 
FROM tbl 
WHERE myDate BETWEEN #date one# AND #date two#;

I wrote with parameters that are predefined

They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:

Alter Procedure [Test]
    @StartDate AS varchar(6) = NULL, 
    @EndDate AS varchar(6) = NULL
AS
...

NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.

Now you can call it without passing any arguments e.g. exec dbo.TEST

Well here is mine: not necessarily the best, but as it is simple it is easy to edit to your taste.

The converter, as it is written now it is not necessary that it is a MultiConverter, but in this wasy it can be extended easily

using System;
using System.Globalization;
using System.Windows;
using System.Windows.Data;

namespace WPFControls
{
    class ShadowConverter:IMultiValueConverter
    {
        #region Implementation of IMultiValueConverter

        public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
        {
            var text = (string) values[0];
            return text == string.Empty
                       ? Visibility.Visible
                       : Visibility.Collapsed;
        }

        public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
        {
            return new object[0];
        }

        #endregion
    }
}

and finally the code behind:

using System.Windows;
using System.Windows.Controls;

namespace WPFControls
{
    /// <summary>
    /// Interaction logic for ShadowedTextBox.xaml
    /// </summary>
    public partial class ShadowedTextBox : UserControl
    {
        public event TextChangedEventHandler TextChanged;

        public ShadowedTextBox()
        {
            InitializeComponent();
        }

        public static readonly DependencyProperty WatermarkProperty =
            DependencyProperty.Register("Watermark",
                                        typeof (string),
                                        typeof (ShadowedTextBox),
                                        new UIPropertyMetadata(string.Empty));

        public static readonly DependencyProperty TextProperty =
            DependencyProperty.Register("Text",
                                        typeof (string),
                                        typeof (ShadowedTextBox),
                                        new UIPropertyMetadata(string.Empty));

        public static readonly DependencyProperty TextChangedProperty =

                                        typeof (TextChangedEventHandler),
                                        typeof (ShadowedTextBox),
                                        new UIPropertyMetadata(null));

        public string Watermark
        {
            get { return (string)GetValue(WatermarkProperty); }
            set
            {
                SetValue(WatermarkProperty, value);
            }
        }

        public string Text
        {
            get { return (string) GetValue(TextProperty); }
            set{SetValue(TextProperty,value);}
        }

        private void textBox_TextChanged(object sender, TextChangedEventArgs e)
        {
            if (TextChanged != null) TextChanged(this, e);
        }

        public void Clear()
        {
            textBox.Clear();
        }

    }
}

You probably shouldn't, and you can probably do what you want to do in a safer and simpler way. Technically to use variable number of arguments in C you include stdarg.h. From that you'll get the va_list type as well as three functions that operate on it called va_start(), va_arg() and va_end().

#include<stdarg.h>

int maxof(int n_args, ...)
{
    va_list ap;
    va_start(ap, n_args);
    int max = va_arg(ap, int);
    for(int i = 2; i <= n_args; i++) {
        int a = va_arg(ap, int);
        if(a > max) max = a;
    }
    va_end(ap);
    return max;
}

If you ask me, this is a mess. It looks bad, it's unsafe, and it's full of technical details that have nothing to do with what you're conceptually trying to achieve. Instead, consider using overloading or inheritance/polymorphism, builder pattern (as in operator<<() in streams) or default arguments etc. These are all safer: the compiler gets to know more about what you're trying to do so there are more occasions it can stop you before you blow your leg off.

I know this is an old question however I've found a much neater way of doing this conversion.

Java

TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 65, getResources().getDisplayMetrics());

Kotlin

TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 65f, resources.displayMetrics)

Travis R is correct. (I wish I could upvote ya.) I just got this working myself. With these routes:

resources :articles do
  resources :comments
end

You get paths like:

/articles/42
/articles/42/comments/99

routed to controllers at

app/controllers/articles_controller.rb
app/controllers/comments_controller.rb

just as it says at http://guides.rubyonrails.org/routing.html#nested-resources, with no special namespaces.

But partials and forms become tricky. Note the square brackets:

<%= form_for [@article, @comment] do |f| %>

Most important, if you want a URI, you may need something like this:

article_comment_path(@article, @comment)

Alternatively:

[@article, @comment]

as described at http://edgeguides.rubyonrails.org/routing.html#creating-paths-and-urls-from-objects

For example, inside a collections partial with comment_item supplied for iteration,

<%= link_to "delete", article_comment_path(@article, comment_item),
      :method => :delete, :confirm => "Really?" %>

What jamuraa says may work in the context of Article, but it did not work for me in various other ways.

There is a lot of discussion related to nested resources, e.g. http://weblog.jamisbuck.org/2007/2/5/nesting-resources

Interestingly, I just learned that most people's unit-tests are not actually testing all paths. When people follow jamisbuck's suggestion, they end up with two ways to get at nested resources. Their unit-tests will generally get/post to the simplest:

# POST /comments
post :create, :comment => {:article_id=>42, ...}

In order to test the route that they may prefer, they need to do it this way:

# POST /articles/42/comments
post :create, :article_id => 42, :comment => {...}

I learned this because my unit-tests started failing when I switched from this:

resources :comments
resources :articles do
  resources :comments
end

to this:

resources :comments, :only => [:destroy, :show, :edit, :update]
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

I guess it's ok to have duplicate routes, and to miss a few unit-tests. (Why test? Because even if the user never sees the duplicates, your forms may refer to them, either implicitly or via named routes.) Still, to minimize needless duplication, I recommend this:

resources :comments
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

Sorry for the long answer. Not many people are aware of the subtleties, I think.

The Factory pattern can almost be seen as a simplified version of the Builder pattern.

In the Factory pattern, the factory is in charge of creating various subtypes of an object depending on the needs.

The user of a factory method doesn't need to know the exact subtype of that object. An example of a factory method createCar might return a Ford or a Honda typed object.

In the Builder pattern, different subtypes are also created by a builder method, but the composition of the objects might differ within the same subclass.

To continue the car example you might have a createCar builder method which creates a Honda-typed object with a 4 cylinder engine, or a Honda-typed object with 6 cylinders. The builder pattern allows for this finer granularity.

Diagrams of both the Builder pattern and the Factory method pattern are available on Wikipedia.

A group of 8 bits is called a byte ( with the exception where it is not :) for certain architectures )

A word is a fixed sized group of bits that are handled as a unit by the instruction set and/or hardware of the processor. That means the size of a general purpose register ( which is generally more than a byte ) is a word

In the C, a word is most often called an integer => int

I use the following for my HTML templates:

$(".main").empty();

var _template = '<p id="myelement">Your HTML Code</p>';
var template = $.parseHTML(_template);
var final = $(template).find("#myelement");

$(".main").append(final.html());

Note: Assuming if you are using jQuery

Also, there was just a typo in your original post.

'min:2|max5' should have been 'min:2|max:5'.
Notice the ":" for the "max" rule.

Another option is to use the cor.test function, instead of lm:

> x <- c(44.4, 45.9, 41.9, 53.3, 44.7, 44.1, 50.7, 45.2, 60.1)
> y <- c( 2.6,  3.1,  2.5,  5.0,  3.6,  4.0,  5.2,  2.8,  3.8)

> mycor = cor.test(x,y)
> mylm = lm(x~y)

# r and rsquared:
> cor.test(x,y)$estimate ** 2
      cor 
0.3262484 
> summary(lm(x~y))$r.squared
[1] 0.3262484

# P.value 

> lmp(lm(x~y))  # Using the lmp function defined in Chase's answer
[1] 0.1081731
> cor.test(x,y)$p.value
[1] 0.1081731

Here's a question and answer for this: Difference between screen.availHeight and window.height()

Has pics too, so you can actually see the differences. Hope this helps.

Basically, $(window).height() give you the maximum height inside of the browser window (viewport), and$(document).height() gives you the height of the document inside of the browser. Most of the time, they will be exactly the same, even with scrollbars.

Hold down the Option key and click where you'd like the cursor to move, and Terminal rushes the cursor that precise spot.

And it works fine, but I am having the concern whether the scripts added to be executed in this manner are being executed asynchronously. If yes then it can happen that work.js runs even before jQuery (or other libraries which I may add in future).

That shouldn't really be a concern: you queue up scripts to be executed in a certain JS context, and that context can't have a race condition as it's single-threaded.

However, the proper way to eliminate this concern is to chain the calls:

chrome.browserAction.onClicked.addListener(function (tab) {
    chrome.tabs.executeScript({
        file: 'thirdParty/jquery-2.0.3.js'
    }, function() {
        // Guaranteed to execute only after the previous script returns
        chrome.tabs.executeScript({
            file: 'work.js'
        });
    });
});

Or, generalized:

function injectScripts(scripts, callback) {
  if(scripts.length) {
    var script = scripts.shift();
    chrome.tabs.executeScript({file: script}, function() {
      if(chrome.runtime.lastError && typeof callback === "function") {
        callback(false); // Injection failed
      }
      injectScripts(scripts, callback);
    });
  } else {
    if(typeof callback === "function") {
      callback(true);
    }
  }
}

injectScripts(["thirdParty/jquery-2.0.3.js", "work.js"], doSomethingElse);

Or, promisified (and brought more in line with the proper signature):

function injectScript(tabId, injectDetails) {
  return new Promise((resolve, reject) => {
    chrome.tabs.executeScript(tabId, injectDetails, (data) => {
      if (chrome.runtime.lastError) {
        reject(chrome.runtime.lastError.message);
      } else {
        resolve(data);
      }
    });
  });
}

injectScript(null, {file: "thirdParty/jquery-2.0.3.js"}).then(
  () => injectScript(null, {file: "work.js"})
).then(
  () => doSomethingElse
).catch(
  (error) => console.error(error)
);

Or, why the heck not, async/await-ed for even clearer syntax:

function injectScript(tabId, injectDetails) {
  return new Promise((resolve, reject) => {
    chrome.tabs.executeScript(tabId, injectDetails, (data) => {
      if (chrome.runtime.lastError) {
        reject(chrome.runtime.lastError.message);
      } else {
        resolve(data);
      }
    });
  });
}

try {
  await injectScript(null, {file: "thirdParty/jquery-2.0.3.js"});
  await injectScript(null, {file: "work.js"});
  doSomethingElse();
} catch (err) {
  console.error(err);
}

Note, in Firefox you can just use browser.tabs.executeScript as it will return a Promise.

printf("format", args) is used to print the data onto the standard output which is often a computer monitor.

sprintf(char *, "format", args) is like printf. Instead of displaying the formated string on the standard output i.e. a monitor, it stores the formated data in a string pointed to by the char pointer (the very first parameter). The string location is the only difference between printf and sprint syntax.

fprintf(FILE *fp, "format", args) is like printf again. Here, instead of displaying the data on the monitor, or saving it in some string, the formatted data is saved on a file which is pointed to by the file pointer which is used as the first parameter to fprintf. The file pointer is the only addition to the syntax of printf.

If stdout file is used as the first parameter in fprintf, its working is then considered equivalent to that of printf.

You can install directly from the repository (note the type="source"):

install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")

You can declare like one of the below options:

char data[] = "Testing String";

or

const char* data = "Testing String";

or

char* data = (char*) "Testing String";

Try this for a one liner that is strict safe.

[bool]$myobject.PSObject.Properties[$propertyName]

For example:

Set-StrictMode -Version latest;
$propertyName = 'Property1';
$myobject = [PSCustomObject]@{ Property0 = 'Value0' };

if ([bool]$myobject.PSObject.Properties[$propertyName]) {
    $value = $myobject.$propertyName;
}

If you prefer attr_accessible, you could use it in Rails 4 too. You should install it like gem:

gem 'protected_attributes'

after that you could use attr_accessible in you models like in Rails 3

Also, and i think that is the best way- using form objects for dealing with mass assignment, and saving nested objects, and you can also use protected_attributes gem that way

class NestedForm
   include  ActiveModel::MassAssignmentSecurity
   attr_accessible :name,
                   :telephone, as: :create_params
   def create_objects(params)
      SomeModel.new(sanitized_params(params, :create_params))
   end
end

My favorite method uses cv2.copyMakeBorder with no border, like so.

copy = cv2.copyMakeBorder(original,0,0,0,0,cv2.BORDER_REPLICATE)

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

updated your ssh key, getting the above message is normal.

Just edit ~/.ssh/known_hosts and delete line 4, as the message pointed you

Offending RSA key in /Users/isaacalves/.ssh/known_hosts:4

or use ssh-keygen to delete the invalid key

ssh-keygen -R "you server hostname or ip"

awk -F " " '($1=="A1") {print $NF}' FILE | tail -n 1

Use awk with field separator -F set to a space " ".

Use the pattern $1=="A1" and action {print $NF}, this will print the last field in every record where the first field is "A1". Pipe the result into tail and use the -n 1 option to only show the last line.

@section is for defining a content are override from a shared view. Basically, it is a way for you to adjust your shared view (similar to a Master Page in Web Forms).

You might find Scott Gu's write up on this very interesting.

Edit: Based on additional question clarification

The @RenderSection syntax goes into the Shared View, such as:

<div id="sidebar">
    @RenderSection("Sidebar", required: false)
</div>

This would then be placed in your view with @Section syntax:

@section Sidebar{
    <!-- Content Here -->
}

In MVC3+ you can either define the Layout file to be used for the view directly or you can have a default view for all views.

Common view settings can be set in _ViewStart.cshtml which defines the default layout view similar to this:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

You can also set the Shared View to use directly in the file, such as index.cshtml directly as shown in this snippet.

@{
    ViewBag.Title = "Corporate Homepage";
    ViewBag.BodyID = "page-home";
    Layout = "~/Views/Shared/_Layout2.cshtml";
}

There are a variety of ways you can adjust this setting with a few more mentioned in this SO answer.

For pandas 0.17 and above, use this :

test = df.sort_values('one', ascending=False)

Since 'one' is a series in the pandas data frame, hence pandas will not accept the arguments in the form of a list.

It depends what kind of UUID you want.

• The standard Java UUID class generates Version 4 (random) UUIDs. (UPDATE - Version 3 (name) UUIDs can also be generated.) It can also handle other variants, though it cannot generate them. (In this case, "handle" means construct UUID instances from long, byte[] or String representations, and provide some appropriate accessors.)

• The Java UUID Generator (JUG) implementation purports to support "all 3 'official' types of UUID as defined by RFC-4122" ... though the RFC actually defines 4 types and mentions a 5th type.

For more information on UUID types and variants, there is a good summary in Wikipedia, and the gory details are in RFC 4122 and the other specifications.

I would recommend taking a look at jQuery UI autocomplete widget. They handled most of the cases there since their code base is more mature than most ones out there.

Below is a link to a demo page so you can verify it works. http://jqueryui.com/demos/autocomplete/#default

You will get the most benefit from reading the source and seeing how they solved it. You can find it here: https://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.autocomplete.js.

Basically they do it all, they bind to input, keydown, keyup, keypress, focus and blur. Then they have special handling for all sorts of keys like page up, page down, up arrow key and down arrow key. A timer is used before getting the contents of the textbox. When a user types a key that does not correspond to a command (up key, down key and so on) there is a timer that explorers the content after about 300 milliseconds. It looks like this in the code:

// switch statement in the 
switch( event.keyCode ) {
            //...
            case keyCode.ENTER:
            case keyCode.NUMPAD_ENTER:
                // when menu is open and has focus
                if ( this.menu.active ) {
                    // #6055 - Opera still allows the keypress to occur
                    // which causes forms to submit
                    suppressKeyPress = true;
                    event.preventDefault();
                    this.menu.select( event );
                }
                break;
            default:
                suppressKeyPressRepeat = true;
                // search timeout should be triggered before the input value is changed
                this._searchTimeout( event );
                break;
            }
// ...
// ...
_searchTimeout: function( event ) {
    clearTimeout( this.searching );
    this.searching = this._delay(function() { // * essentially a warpper for a setTimeout call *
        // only search if the value has changed
        if ( this.term !== this._value() ) { // * _value is a wrapper to get the value *
            this.selectedItem = null;
            this.search( null, event );
        }
    }, this.options.delay );
},

The reason to use a timer is so that the UI gets a chance to be updated. When Javascript is running the UI cannot be updated, therefore the call to the delay function. This works well for other situations such as keeping focus on the textbox (used by that code).

So you can either use the widget or copy the code into your own widget if you are not using jQuery UI (or in my case developing a custom widget).

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

For bash scripts this would be the easiest way:

# In the form major.minor.micro e.g. '3.6.8'
# The second part excludes the 'Python ' prefix 
PYTHON_VERSION=`python3 --version | awk '{print $2}'`
echo "python3 version: ${PYTHON_VERSION}"
python3 version: 3.6.8

And if you just need the major.minor version (e.g. 3.6) you can either use the above and then pick the first 3 characters:

PYTHON_VERSION=`python3 --version | awk '{print $2}'`
echo "python3 major.minor: ${PYTHON_VERSION:0:3}"
python3 major.minor: 3.6

or

PYTHON_VERSION=`python3 -c 'import sys; print(str(sys.version_info[0])+"."+str(sys.version_info[1]))'`
echo "python3 major.minor: ${PYTHON_VERSION}"
python3 major.minor: 3.6

I came across this question while searching for a way to check if a module is loaded from the command line and would like to share my thoughts for the ones coming after me and looking for the same:

Linux/UNIX script file method: make a file module_help.py:

#!/usr/bin/env python

help('modules')

Then make sure it's executable: chmod u+x module_help.py

And call it with a pipe to grep:

./module_help.py | grep module_name

Invoke the built-in help system. (This function is intended for interactive use.) If no argument is given, the interactive help system starts on the interpreter console. If the argument is a string, then the string is looked up as the name of a module, function, class, method, keyword, or documentation topic, and a help page is printed on the console. If the argument is any other kind of object, a help page on the object is generated.

Interactive method: in the console load python

>>> help('module_name')

If found quit reading by typing q
To exit the python interactive session press Ctrl + D

Windows script file method also Linux/UNIX compatible, and better overall:

#!/usr/bin/env python

import sys

help(sys.argv[1])

Calling it from the command like:

python module_help.py site  

Would output:

Help on module site:

NAME site - Append module search paths for third-party packages to sys.path.

FILE /usr/lib/python2.7/site.py

MODULE DOCS http://docs.python.org/library/site

DESCRIPTION
...
:

and you'd have to press q to exit interactive mode.

Using it unknown module:

python module_help.py lkajshdflkahsodf

Would output:

no Python documentation found for 'lkajshdflkahsodf'

and exit.

I think you are trying to check whether the array is empty or not.You can do like this :

@if(!$result->isEmpty())
     // $result is not empty
@else
    // $result is empty
@endif

Reference isEmpty()

In case you are using Visual Studio 2012, for this to work and in order to make reference to Microsoft Office Core, you have to make the reference through Visual Studio by clicking on the top menu's Project, Add Reference, Extensions button and checking office which is now (14.0).

An expansion on Eran's answer that was the top answer, if you have a bunch of layers of lists, you can keep flatmapping them.

This also comes with a handy way of filtering as you go down the layers if needed as well.

So for example:

List<List<List<List<List<List<Object>>>>>> multiLayeredList = ...

List<Object> objectList = multiLayeredList
    .stream()
    .flatmap(someList1 -> someList1
        .stream()
        .filter(...Optional...))
    .flatmap(someList2 -> someList2
        .stream()
        .filter(...Optional...))
    .flatmap(someList3 -> someList3
        .stream()
        .filter(...Optional...))
    ...
    .collect(Collectors.toList())

This is would be similar in SQL to having SELECT statements within SELECT statements.

You can launch the correct version of Spyder by launching from Ananconda's Navigator. From the dropdown, switch to your desired environment and then press the launch Spyder button. You should be able to check the results right away.

You would usually use map for that kind of thing.

buttonsListArr = initialArr.map(buttonInfo => (
  <Button ... key={buttonInfo[0]}>{buttonInfo[1]}</Button>
);

(key is a necessary prop whenever you do mapping in React. The key needs to be a unique identifier for the generated component)

As a side, I would use an object instead of an array. I find it looks nicer:

initialArr = [
  {
    id: 1,
    color: "blue",
    text: "text1"
  },
  {
    id: 2,
    color: "red",
    text: "text2"
  },
];

buttonsListArr = initialArr.map(buttonInfo => (
  <Button ... key={buttonInfo.id}>{buttonInfo.text}</Button>
);

In Linux

First of all set ANDROID_HOME in .bashrc file

Run command

sudo gedit ~/.bashrc

set andoid sdk path where you have installed

export ANDROID_HOME=/opt/android-sdk-linux 
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

to reload file run command

source ~/.bashrc

Now check installed platform, run command

ionic platform

Output

Installed platforms:
  android 6.0.0
Available platforms: 
  amazon-fireos ~3.6.3 (deprecated)
  blackberry10 ~3.8.0
  browser ~4.1.0
  firefoxos ~3.6.3
  ubuntu ~4.3.4
  webos ~3.7.0

if android already installed then need to remove and install again

ionic platform rm android
ionic platform add android

If not installed already please add android platform

ionic platform add android

Please make sure you have added android platform without sudo command

if you still getting error in adding android platfrom like following

Error: EACCES: permission denied, open '/home/ubuntu/.cordova/lib/npm_cache/cordova-android/6.0.0/package/package.json'

Please go to /home/ubuntu/ and remove .cordova folder from there

cd /home/ubuntu/
sudo rm -r .cordova

Now run following command again

ionic platform add android

after adding platform successfully you will be able to build andoid in ionic.

Thanks

It must be here, because accepted answer from 2012

In 2018 and modern browsers you can send a custom event from iframe to parent window.

iframe:

var data = { foo: 'bar' }
var event = new CustomEvent('myCustomEvent', { detail: data })
window.parent.document.dispatchEvent(event)

parent:

window.document.addEventListener('myCustomEvent', handleEvent, false)
function handleEvent(e) {
  console.log(e.detail) // outputs: {foo: 'bar'}
}

PS: Of course, you can send events in opposite direction same way.

document.querySelector('#iframe_id').contentDocument.dispatchEvent(event)

In the same location where the JVM's stdout is placed. If you have a Tomcat server, this will be the catalina_(date).out file.

Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.

I'd go with:

r = re.search("\d+", ch)
result = return r.group(0) if r else ""

re.search only looks for the first match in the string anyway, so I think it makes your intent slightly more clear than using findall.

See "Can I Use" for the full list of IE11 Flexbox bugs and more

There are numerous Flexbox bugs in IE11 and other browsers - see flexbox on Can I Use -> Known Issues, where the following are listed under IE11:

• IE 11 requires a unit to be added to the third argument, the flex-basis property
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property
• IE 11 does not vertically align items correctly when min-height is used

Also see Philip Walton's Flexbugs list of issues and workarounds.

.htpasswd entries are HASHES. They are not encrypted passwords. Hashes are designed not to be decryptable. Hence there is no way (unless you bruteforce for a loooong time) to get the password from the .htpasswd file.

What you need to do is apply the same hash algorithm to the password provided to you and compare it to the hash in the .htpasswd file. If the user and hash are the same then you're a go.

Since I've Seen a lot of methods here but I've found a simplest method for myself.Maybe it will help someone.

$slug = strtolower(preg_replace('/[^a-zA-Z0-9\-]/', '',preg_replace('/\s+/', '-', $string) ));

To directly answer the OP, take a look at this guy's site: Thomas Hunter Notepad++ Tidy for XML. Simple steps to follow and you get very nice formatting of your XML right inside NPP. So far the only anomaly I've found is with nested self closing elements EG:

<OuterTag>Text for outer element<SelfClosingTag/></OuterTag>

Will be tidied up to:

<OuterTag>Text for outer element
<SelfClosingTag/></OuterTag>

There may be a way to fix this, but for the time being, it's managed to reduce the number of lines in my document by 300k and this particular anomaly can be worked around.

Use this code:

public static void main(String[] args) {
    String test = "A|B|C||D";

    String[] result = test.split("\\|");

    for (String s : result) {
        System.out.println(">" + s + "<");
    }
}

If I understand correctly it appears you want to run the jars in a separate process from inside your java GUI application.

To do this you can use:

// Run a java app in a separate system process
Process proc = Runtime.getRuntime().exec("java -jar A.jar");
// Then retreive the process output
InputStream in = proc.getInputStream();
InputStream err = proc.getErrorStream();

Its always good practice to buffer the output of the process.

The complete steps to add the algorithms to the RECEIVING server (the one you are connecting to). I'm assuming this is a Linux server.

sudo /etc/ssh/sshd_config

Add this to the file (it can be at the end):

KexAlgorithms [email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

Then restart the SSH server:

sudo service sshd restart
