Programs & Examples On #Single sign on

[disclaimer: I'm one of the contributors]

We built a very simple free/opensource component that adds SAML support for ASP.NET apps https://github.com/jitbit/AspNetSaml

Basically it's just one short C# file you can throw into your project (or install via Nuget) and use it with your app

https://support.procore.com/faq/what-is-the-difference-between-sp-and-idp-initiated-sso

There is much more to this but this is a high level overview on which is which.

Procore supports both SP- and IdP-initiated SSO:

Identity Provider Initiated (IdP-initiated) SSO. With this option, your end users must log into your Identity Provider's SSO page (e.g., Okta, OneLogin, or Microsoft Azure AD) and then click an icon to log into and open the Procore web application. To configure this solution, see Configure IdP-Initiated SSO for Microsoft Azure AD, Configure Procore for IdP-Initated Okta SSO, or Configure IdP-Initiated SSO for OneLogin. OR Service Provider Initiated (SP-initiated) SSO. Referred to as Procore-initiated SSO, this option gives your end users the ability to sign into the Procore Login page and then sends an authorization request to the Identify Provider (e.g., Okta, OneLogin, or Microsoft Azure AD). Once the IdP authenticates the user's identify, the user is logged into Procore. To configure this solution, see Configure Procore-Initiated SSO for Microsoft Azure Active Directory, Configure Procore-Initiated SSO for Okta, or Configure Procore-Initiated SSO for OneLogin.

About this I think you can reference to http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-tech-overview-2.0.html.

Here're my understandings about this, with the Identity Federation Use Case to give a details for those concepts:

• Persistent identifiers-

IdP provides the Persistent identifiers, they are used for linking to the local accounts in SPs, but they identify as the user profile for the specific service each alone. For example, the persistent identifiers are kind of like : johnForAir, jonhForCar, johnForHotel, they all just for one specified service, since it need to link to its local identity in the service.

• Transient identifiers-

Transient identifiers are what IdP tell the SP that the users in the session have been granted to access the resource on SP, but the identities of users do not offer to SP actually. For example, The assertion just like “Anonymity(Idp doesn’t tell SP who he is) has the permission to access /resource on SP”. SP got it and let browser to access it, but still don’t know Anonymity' real name.

• unspecified identifiers-

The explanation for it in the spec is "The interpretation of the content of the element is left to individual implementations". Which means IdP defines the real format for it, and it assumes that SP knows how to parse the format data respond from IdP. For example, IdP gives a format data "UserName=XXXXX Country=US", SP get the assertion, and can parse it and extract the UserName is "XXXXX".

It's really useful, I used it with a slight change:

filename=directory.list(new FilenameFilter() { 
    public boolean accept(File dir, String filename) { 
        return filename.startsWith(ipro); 
    }
});

SELECT x.name, x.summary, (x.summary / COUNT(*)) as percents_of_total
FROM tbl t
INNER JOIN 
(SELECT name, SUM(value) as summary
FROM tbl
WHERE year BETWEEN 2000 AND 2001
GROUP BY name) x ON x.name = t.name
GROUP BY x.name, x.summary

My favorite no-conflict-friendly construct:

jQuery(function($) {
  // ...
});

Calling jQuery with a function pointer is a shortcut for $(document).ready(...)

Or as we say in coffeescript:

jQuery ($) ->
  # code here

A bit late, but you can easily find a string with this query

DECLARE
@search_string  VARCHAR(100),
@table_name     SYSNAME,
@table_id       INT,
@column_name    SYSNAME,
@sql_string     VARCHAR(2000)

SET @search_string = 'StringtoSearch'

DECLARE tables_cur CURSOR FOR SELECT ss.name +'.'+ so.name [name], object_id FROM sys.objects so INNER JOIN sys.schemas ss ON so.schema_id = ss.schema_id WHERE  type = 'U'

OPEN tables_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id

WHILE (@@FETCH_STATUS = 0)
BEGIN
    DECLARE columns_cur CURSOR FOR SELECT name FROM sys.columns WHERE object_id = @table_id 
        AND system_type_id IN (167, 175, 231, 239)

    OPEN columns_cur

    FETCH NEXT FROM columns_cur INTO @column_name
        WHILE (@@FETCH_STATUS = 0)
        BEGIN
            SET @sql_string = 'IF EXISTS (SELECT * FROM ' + @table_name + ' WHERE [' + @column_name + '] 
            LIKE ''%' + @search_string + '%'') PRINT ''' + @table_name + ', ' + @column_name + ''''

            EXECUTE(@sql_string)

        FETCH NEXT FROM columns_cur INTO @column_name
        END

    CLOSE columns_cur

DEALLOCATE columns_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id
END

CLOSE tables_cur
DEALLOCATE tables_cur

I tried this tool and it gave me good results.

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

To send javascript obj to php using json and ajax:

js:

var dataPost = {
   "var": "foo"
};
var dataString = JSON.stringify(dataPost);

$.ajax({
   url: 'server.php',
   data: {myData: dataString},
   type: 'POST',
   success: function(response) {
      alert(response);
   }
});

to use that object in php:

$obj = json_decode($_POST["myData"]);

echo $obj->var;

    select 
       @selectoneCount = case @Temp
       when 1 then (@selectoneCount+1)
       when 2 then (@selectoneCount+1)
       end

   select  @selectoneCount 

This is how it was on the Microsoft site, with me just tweaking the SPSite and SPWeb since these might vary from environment to environment and it helps not to have to hard-code these:

using (SPSite oSiteCollection = new SPSite(SPContext.Current.Site.Url))
{
    using (SPWeb oWeb = oSiteCollection.OpenWeb(SPContext.Current.Web))
    {
        SPList oList = oWeb.Lists["Announcements"];
        // You may also use 
        // SPList oList = oWeb.GetList("/Lists/Announcements");
        // to avoid querying all of the sites' lists
        SPListItem oListItem = oList.Items.Add();
        oListItem["Title"] = "My Item";
        oListItem["Created"] = new DateTime(2004, 1, 23);
        oListItem["Modified"] = new DateTime(2005, 10, 1);
        oListItem["Author"] = 3;
        oListItem["Editor"] = 3;
        oListItem.Update();
    }
}

I saw another question on just this topic recently (streaming pdf into iframe using dataurl only works in chrome).

I've constructed pdfs in the ast and streamed them to the browser. I was creating them first with fdf, then with a pdf class I wrote myself - in each case the pdf was created from data retrieved from a COM object based on a couple of of GET params passed in via the url.

From looking at your data sent recieved in the ajax call, it looks like you're nearly there. I haven't played with the code for a couple of years now and didn't document it as well as I'd have cared to, but - I think all you need to do is set the target of an iframe to be the url you get the pdf from. Though this may not work - the file that oututs the pdf may also have to outut a html response header first.

In a nutshell, this is the output code I used:

//We send to a browser
header('Content-Type: application/pdf');
if(headers_sent())
    $this->Error('Some data has already been output, can\'t send PDF file');
header('Content-Length: '.strlen($this->buffer));
header('Content-Disposition: inline; filename="'.$name.'"');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
ini_set('zlib.output_compression','0');
echo $this->buffer;

So, without seeing the full response text fro the ajax call I can't really be certain what it is, though I'm inclined to think that the code that outputs the pdf you're requesting may only be doig the equivalent of the last line in the above code. If it's code you have control over, I'd try setting the headers - then this way the browser can just deal with the response text - you don't have to bother doing a thing to it.

I simply constructed a url for the pdf I wanted (a timetable) then created a string that represented the html for an iframe of the desired sie, id etc that used the constructed url as it's src. As soon as I set the inner html of a div to the constructed html string, the browser asked for the pdf and then displayed it when it was received.

function  showPdfTt(studentId)
{
    var url, tgt;
    title = byId("popupTitle");
    title.innerHTML = "Timetable for " + studentId;
    tgt = byId("popupContent");
    url = "pdftimetable.php?";
    url += "id="+studentId;
    url += "&type=Student";
    tgt.innerHTML = "<iframe onload=\"centerElem(byId('box'))\" src='"+url+"' width=\"700px\" height=\"500px\"></iframe>";
}

EDIT: forgot to mention - you can send binary pdf's in this manner. The streams they contain don't need to be ascii85 or hex encoded. I used flate on all the streams in the pdf and it worked fine.

From what I can see, none of the above can handle normal parameters and array parameters. Here's one that does.

function removeURLParameter(param, url) {
    url = decodeURI(url).split("?");
    path = url.length == 1 ? "" : url[1];
    path = path.replace(new RegExp("&?"+param+"\\[\\d*\\]=[\\w]+", "g"), "");
    path = path.replace(new RegExp("&?"+param+"=[\\w]+", "g"), "");
    path = path.replace(/^&/, "");
    return url[0] + (path.length
        ? "?" + path
        : "");
}

function addURLParameter(param, val, url) {
    if(typeof val === "object") {
        // recursively add in array structure
        if(val.length) {
            return addURLParameter(
                param + "[]",
                val.splice(-1, 1)[0],
                addURLParameter(param, val, url)
            )
        } else {
            return url;
        }
    } else {
        url = decodeURI(url).split("?");
        path = url.length == 1 ? "" : url[1];
        path += path.length
            ? "&"
            : "";
        path += decodeURI(param + "=" + val);
        return url[0] + "?" + path;
    }
}

How to use it:

url = location.href;
    -> http://example.com/?tags[]=single&tags[]=promo&sold=1

url = removeURLParameter("sold", url)
    -> http://example.com/?tags[]=single&tags[]=promo

url = removeURLParameter("tags", url)
    -> http://example.com/

url = addURLParameter("tags", ["single", "promo"], url)
    -> http://example.com/?tags[]=single&tags[]=promo

url = addURLParameter("sold", 1, url)
    -> http://example.com/?tags[]=single&tags[]=promo&sold=1

Of course, to update a parameter, just remove then add. Feel free to make a dummy function for it.

You can set Execution time-out in seconds.

std::hex is defined in <ios> which is included by <iostream>. But to use things like std::setprecision/std::setw/std::setfill/etc you have to include <iomanip>.

list=[1.1412, 4.3453, 5.8709, 0.1314]
list.index(min(list))

Will give you first index of minimum.

For me the error occurred due to my browser using a cached version of the js file containing the module. Clearing the cache and reloading the page solved the problem.

According to documentation it is:

spring.jpa.show-sql=true # Enable logging of SQL statements.

This is due to a security restriction.

I found out that the security restriction is only when the <input type="file"/> is set to display:none; or is visbilty:hidden.

So i tried positioning it outside the viewport by setting position:absolute and top:-100px; and voilà it works.

see http://jsfiddle.net/DSARd/1/

call it a hack.

Hope that works for you.

Just to complete Amit Garg answer, there are several ways to inject dependencies in AngularJS.

You can also use $inject to add a dependency:

var MyController = function($scope, $http) {
  // ...
}
MyController.$inject = ['$scope', '$http'];

A simple safe way would be to use an alias. Place this into ~/.bashrc file: if you have gedit editor use

gedit ~/.bashrc

to go into the bashrc file and then at the top of the bashrc file make the following change.

alias python=python3

After adding the above in the file. run the below command

source ~/.bash_aliases or source ~/.bashrc

example:

$ python --version

Python 2.7.6

$ python3 --version

Python 3.4.3

$ alias python=python3

$ python --version

Python 3.4.3

Here's one:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?lngWId=8&txtCodeId=1786

Another:

function ping($host, $port, $timeout) { 
  $tB = microtime(true); 
  $fP = fSockOpen($host, $port, $errno, $errstr, $timeout); 
  if (!$fP) { return "down"; } 
  $tA = microtime(true); 
  return round((($tA - $tB) * 1000), 0)." ms"; 
}

//Echoing it will display the ping if the host is up, if not it'll say "down".
echo ping("www.google.com", 80, 10);  

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

The su command does not execute anything, it just raise your privileges.

Try adb shell su -c YOUR_COMMAND.

I usually use Gloss library to serialize or deserialize JSON in iOS. For example, I have JSON that looks like this:

{"ABDC":[{"AB":"qwerty","CD":"uiop"}],[{"AB":"12334","CD":"asdf"}]}

First, I model the JSON array in Gloss struct:

Struct Struct_Name: Decodable {
   let IJ: String?
   let KL: String?
   init?(json: JSON){
       self.IJ = "AB" <~~ json
       self.KL = "CD" <~~ json
   }
}

And then in Alamofire responseJSON, I do this following thing:

Alamofire.request(url, method: .get, paramters: parametersURL).validate(contentType: ["application/json"]).responseJSON{ response in
 switch response.result{
   case .success (let data):
    guard let value = data as? JSON,
       let eventsArrayJSON = value["ABDC"] as? [JSON]
    else { fatalError() }
    let struct_name = [Struct_Name].from(jsonArray: eventsArrayJSON)//the JSON deserialization is done here, after this line you can do anything with your JSON
    for i in 0 ..< Int((struct_name?.count)!) {
       print((struct_name?[i].IJ!)!)
       print((struct_name?[i].KL!)!)
    }
    break

   case .failure(let error):
    print("Error: \(error)")
    break
 }
}

The output from the code above:

qwerty
uiop
1234
asdf

Dynamic Programming is often called Memoization!

1.Memoization is the top-down technique(start solving the given problem by breaking it down) and dynamic programming is a bottom-up technique(start solving from the trivial sub-problem, up towards the given problem)

2.DP finds the solution by starting from the base case(s) and works its way upwards. DP solves all the sub-problems, because it does it bottom-up

Unlike Memoization, which solves only the needed sub-problems

1. DP has the potential to transform exponential-time brute-force solutions into polynomial-time algorithms.

2. DP may be much more efficient because its iterative

On the contrary, Memoization must pay for the (often significant) overhead due to recursion.

To be more simple, Memoization uses the top-down approach to solve the problem i.e. it begin with core(main) problem then breaks it into sub-problems and solve these sub-problems similarly. In this approach same sub-problem can occur multiple times and consume more CPU cycle, hence increase the time complexity. Whereas in Dynamic programming same sub-problem will not be solved multiple times but the prior result will be used to optimize the solution.

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

Imho one of the simplest Solutions is: -

//MIN NUMBER
Collections.sort(listOfNumbers);
listOfNumbers.get(0);

//MAX NUMBER
Collections.sort(listOfNumbers);
Collections.reverse(listOfNumbers);
listOfNumbers.get(0);

I could resolve this problem by updating macOS and XCode.

If the OP is trying to determine the history that was traversed by a branch when a particular commit was created ("find out what branch a commit comes from given its SHA-1 hash value"), then without the reflog there aren't any records in the Git object database that shows what named branch was bound to what commit history.

(I posted this as an answer in reply to a comment.)

Hopefully this script illustrates my point:

rm -rf /tmp/r1 /tmp/r2; mkdir /tmp/r1; cd /tmp/r1
git init; git config user.name n; git config user.email [email protected]
git commit -m"empty" --allow-empty; git branch -m b1; git branch b2
git checkout b1; touch f1; git add f1; git commit -m"Add f1"
git checkout b2; touch f2; git add f2; git commit -m"Add f2"
git merge -m"merge branches" b1; git checkout b1; git merge b2
git clone /tmp/r1 /tmp/r2; cd /tmp/r2; git fetch origin b2:b2
set -x;
cd /tmp/r1; git log --oneline --graph --decorate; git reflog b1; git reflog b2;
cd /tmp/r2; git log --oneline --graph --decorate; git reflog b1; git reflog b2;

The output shows the lack of any way to know whether the commit with 'Add f1' came from branch b1 or b2 from the remote clone /tmp/r2.

• contentType is the HTTP header sent to the server, specifying a particular format.
  Example: I'm sending JSON or XML
• dataType is you telling jQuery what kind of response to expect.
  Expecting JSON, or XML, or HTML, etc. The default is for jQuery to try and figure it out.

The $.ajax() documentation has full descriptions of these as well.

In your particular case, the first is asking for the response to be in UTF-8, the second doesn't care. Also the first is treating the response as a JavaScript object, the second is going to treat it as a string.

So the first would be:

success: function(data) {
  // get data, e.g. data.title;
}

The second:

success: function(data) {
  alert("Here's lots of data, just a string: " + data);
}

if you are in base:

(base) HP-Compaq-Elite-8300-CMT:~$ 

remove env_name by:

conda env remove -n env_name

if you are already in env_name environment :

(env_name) HP-Compaq-Elite-8300-CMT:~$ 

deactivate then remove by :

conda deactivate
conda env remove -n env_name

if you want to verify wich file was created first,you can structure your file name by appending system date when you create a series of files.

@Redu's solution is a good solution

arrOfObj.map(o => o.isActive = true;) but Array.map still counts as looping through all items.

if you absolutely don't want to have any looping here's a dirty hack :

Object.defineProperty(Object.prototype, "isActive",{
  value: true,
  writable: true,
  configurable: true,
  enumerable: true
});

my advice is not to use it carefully though, it will patch absolutely all javascript Objects (Date, Array, Number, String or any other that inherit Object ) which is really bad practice...

Above answers are pretty sufficient. Additional to the onChange, if you upload a file using drag and drop events, you can get the file in drop event by accessing eventArgs.dataTransfer.files.

Use the DecimalFormat class to format the double

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')

Note that the value returned by the stored procedure is being return into :Z

Though late in answering, this is a hard one to Google (the single quotes) and it’s not clear what’s happening. I don't have the reputation yet to comment or ask for scope (or post 3 links), so this answer may be a little tedious.

To answer fast, you may have multiple Gradle plugins in your project.

Synchronize Gradle Wrapper and Plugins

My issue seemed to start with a corrupted IML file. Android Studio (between closing and reopening a project) began complaining an IML was gone (it wasn’t) and a module should be deleted, which I declined. It persisted, I upgraded to AS 0.8.7 (canary channel) and got stuck on the OP issue (Task '' not found in root project). This completely blocked builds so I had to dig in to Gradle.

My repair steps on OSX (please adjust for Windows):

1. Upgrade Android Studio to 0.8.7
   • Preferences | Updates | Switch "Beta Channel" to "Canary Channel", then do a Check Now.
   • You might be able to skip this.

2. Checked the Gradle wrapper (currently 1.12.2; don’t try to use 2.0 at this time).

   • Assuming you don’t need a particular version, use the latest supported distribution

     $ vi ~/project/gradle-wrapper.properties ... distributionUrl=http\://services.gradle.org/distributions/gradle-1.12-all.zip

   • This can be set in Android Studio at Preferences | Gradle (but 0.8.7 was giving me ‘invalid location’ errors).

   • The 'wrapper' is just a copy of Gradle for each Android Studio project. It allows you to have Gradle 2 in your OS, and different versions in your projects. The Android Developer docs explain that here.
   • Then adjust your build.gradle files for the plugin. The Gradle plugin version must be compatible with the distribution/wrapper version, for the whole project. As the Tools documentation (tools.android.com/tech-docs/new-build-system/user-guide#TOC-Requirements) is slightly out of date, you can set the plugin version too low (like 0.8.0) and Android Studio will throw an error with the acceptable range for the wrapper.

Example, in build.gradle, you have this plugin:

dependencies {
    classpath "com.android.tools.build:gradle:0.12.+"
}

You can try switching it to the exact version, like this:

dependencies {
    classpath "com.android.tools.build:gradle:0.12.2"
}

and (after recording what version you’re changing from in each case) verifying that every build.gradle file in your project pulls in the same plugin version. Keeping the “+” should work (for 0.12.0, 0.12.1, 0.12.2, etc), but my build succeeded when I updated Google’s Volley library (originally gradle:0.8.+) and my main project (originally 0.12.+) to the fixed version: gradle:0.12.2.

Other checks

1. Ensure you don’t have two Android Application modules in the same Project

   • This may interact with the final solution (different Gradle versions, above), and cause

     UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define (various classes)

   • To check, Build | Make Project should not pop up a window asking what application you want to make.

2. Invalidate your caches
   • File | Invalidate Caches / Restart (stackoverflow.com/a/19223269/513413)
3. If step 2 doesn't work, delete ~/.gradle/ (www.wuttech.com/index.php/tag/groovy-lang-closure/)
   • Quit Android Studio
   • $ rm -rf ~/.gradle/
   • Start Android Studio, then sync:
     • Tools | Android | Sync Project with Gradle Files
   • Repeat this entire sequence (quit...sync) a few times before giving up.
4. Clean the project
   • Build | Clean Project

If You See This...

In my recent builds, I kept seeing horrible fails (pages of exceptions) but within seconds the messages would clear, build succeeded and the app deployed. Since I could never explain it and the app worked, I never noticed that I had two Gradle plugins in my project. So I think the Gradle plugins fought each other; one crashed, the other lost its state and reported the error.

If you have time, the 1-hour video "A Gentle Introduction to Gradle" (www.youtube.com/watch?v=OFUEb7pLLXw) really helped me approach the Gradle build files, tasks, build decisions, etc.

Disclaimer

I'm learning this entire stack, on a foreign OS, after working a different career...all at the same time and under pressure. In the last few months I have hit every wall I think Android has; I've been here quite often and this is my first post. I thought this was a hard fix, so I sincerely apologize if the quality of my answer reflects the difficulty I had in getting to it.

One of the comments by @stivlo deserves to be an answer:

You can use the Amazon service http://checkip.amazonaws.com

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class IpChecker {

    public static String getIp() throws Exception {
        URL whatismyip = new URL("http://checkip.amazonaws.com");
        BufferedReader in = null;
        try {
            in = new BufferedReader(new InputStreamReader(
                    whatismyip.openStream()));
            String ip = in.readLine();
            return ip;
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

Run either of these a few second apart. You'll detect the high CPU connection. Or: stored CPU in a local variable, WAITFOR DELAY, compare stored and current CPU values

select * from master..sysprocesses
where status = 'runnable' --comment this out
order by CPU
desc

select * from master..sysprocesses
order by CPU
desc

May not be the most elegant but it'd effective and quick.

If you don't create a new user when you installed jenkins, then:

user: admin pass: go to C:\Program Files (x86)\Jenkins\secrets and open the file initialAdminPassword

It started to work after I closed Docker app

This is an easy way to get a successful response from the server like PHP echo otherwise an error message.

BufferedReader br = null;
if (conn.getResponseCode() == 200) {
    br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String strCurrentLine;
        while ((strCurrentLine = br.readLine()) != null) {
               System.out.println(strCurrentLine);
        }
} else {
    br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
    String strCurrentLine;
        while ((strCurrentLine = br.readLine()) != null) {
               System.out.println(strCurrentLine);
        }
}

The imshow() function with parameters interpolation='nearest' and cmap='hot' should do what you want.

import matplotlib.pyplot as plt
import numpy as np

a = np.random.random((16, 16))
plt.imshow(a, cmap='hot', interpolation='nearest')
plt.show()

PAUSE

The question is why does the limitation still exist. Surely modern Windows can increase the side of MAX_PATH to allow longer paths. Why has the limitation not been removed?

• The reason it cannot be removed is that Windows promised it would never change.

Through API contract, Windows has guaranteed all applications that the standard file APIs will never return a path longer than 260 characters.

Consider the following correct code:

WIN32_FIND_DATA findData;

FindFirstFile("C:\Contoso\*", ref findData);

Windows guaranteed my program that it would populate my WIN32_FIND_DATA structure:

WIN32_FIND_DATA {
   DWORD    dwFileAttributes;
   FILETIME ftCreationTime;
   FILETIME ftLastAccessTime;
   FILETIME ftLastWriteTime;
   //...
   TCHAR    cFileName[MAX_PATH];
   //..
}

My application didn't declare the value of the constant MAX_PATH, the Windows API did. My application used that defined value.

My structure is correctly defined, and only allocates 592 bytes total. That means that i am only able to receive a filename that is less than 260 characters. Windows promised me that if i wrote my application correctly, my application would continue to work in the future.

If Windows were to allow filenames longer than 260 characters then my existing application (which used the correct API correctly) would fail.

For anyone calling for Microsoft to change the MAX_PATH constant, they first need to ensure that no existing application fails. For example, i still own and use a Windows application that was written to run on Windows 3.11. It still runs on 64-bit Windows 10. That is what backwards compatibility gets you.

Microsoft did create a way to use the full 32,768 path names; but they had to create a new API contract to do it. For one, you should use the Shell API to enumerate files (as not all files exist on a hard drive or network share).

But they also have to not break existing user applications. The vast majority of applications do not use the shell api for file work. Everyone just calls FindFirstFile/FindNextFile and calls it a day.

Not sure about getting an IntPtr to an array, but you can copy the data for use with unmanaged code by using Mashal.Copy:

IntPtr unmanagedPointer = Marshal.AllocHGlobal(bytes.Length);
Marshal.Copy(bytes, 0, unmanagedPointer, bytes.Length);
// Call unmanaged code
Marshal.FreeHGlobal(unmanagedPointer);

Alternatively you could declare a struct with one property and then use Marshal.PtrToStructure, but that would still require allocating unmanaged memory.

Edit: Also, as Tyalis pointed out, you can also use fixed if unsafe code is an option for you

Alt + Right Arrow and Alt + Numpad 6 (if Num Lock is disabled) are also possibilities.

The simplest method for removing white space anywhere in the string.

 public String removeWhiteSpaces(String returnString){
    returnString = returnString.trim().replaceAll("^ +| +$|( )+", " ");
    return returnString;
}

For anyone who is still having this issue, this worked for me:

    cordova platform update android@latest

then build and it will automatically download the newest gradle version and should work

You just have to read the laravel installation page:

1. Install Composer if not already installed
2. Open a command line and do:

composer global require "laravel/installer"

Inside your htdocs or www directory, use either:

laravel new appName

(this can lead to an error on windows computers while using latest Laravel (1.3.2)) or:

composer create-project --prefer-dist laravel/laravel appName

(this works also on windows) to create a project called "appName".

To use "php artisan xyz" you have to be inside your project root! as artisan is a file php is going to use... Simple as that ;)

I had the same error, but in Ubuntu 14.04 inside Windows 10 (Bash on Ubuntu on Windows). All I did to overcome the error was to update the Creators update, which then allowed me to install 16.04 version of Ubuntu bash and then after installing newest version of node (by this steps) I installed also the newest version of npm and then the nodemon started to work properly.

>>> range(6, 0, -1)
[6, 5, 4, 3, 2, 1]

scanf("%2000s %2000[^\n]", a, b);

Since no one mention: In C#, an array is a list. MyClass[] and List<MyClass> both implement IList<MyClass>. (e.g. void Foo(IList<int> foo) can be called like Foo(new[] { 1, 2, 3 }) or Foo(new List<int> { 1, 2, 3 }) )

So, if you are writing a method that accepts a List<MyClass> as an argument, but uses only subset of features, you may want to declare as IList<MyClass> instead for callers' convenience.

Details:

• Why array implements IList?
• How do arrays in C# partially implement IList<T>?

Recently I learned of the following syntax:

DELETE (SELECT *
        FROM productfilters pf
        INNER JOIN product pr
            ON pf.productid = pr.id
        WHERE pf.id >= 200
            AND pr.NAME = 'MARK')

I think it looks much cleaner then other proposed code.

Maybe you could do

SELECT * FROM table LIMIT 10000 OFFSET FLOOR(RAND() * 190000)

I had this issue and it was because the machine running the application isnt trusted for delegation on the domain by active directory. If it is a .net app running under an application pool identity DOMAIN_application.environment for example.. the identity can't make calls out to SQL unless the machine is trusted.

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait(); 

var string = 'test- _ 0Test';
string.match(/^[-_ a-zA-Z0-9]+$/)

A lot of the answers given so far are pretty good, but you must clearly define what it is exactly that you want.

If you would like a alphabetical character followed by any number of non-white-space characters (note that it would also include numbers!) then you should use this:

^[A-Za-z]\S*$

If you would like to include only alpha-numeric characters and certain symbols, then use this:

^[A-Za-z][A-Za-z0-9!@#$%^&*]*$

Your original question looks like you are trying to include the space character as well, so you probably want something like this:

^[A-Za-z ][A-Za-z0-9!@#$%^&* ]*$

And that is my final answer!

I suggest taking some time to learn more about regular expressions. They are the greatest thing since sliced bread!

Try this syntax reference page (that site in general is very good).

pip install str2bool

>>> from str2bool import str2bool
>>> str2bool('Yes')
True
>>> str2bool('FaLsE')
False

Rather then write a lot of code, just do this:

{         
   dynamic tableNameAttribute = typeof(T).CustomAttributes.FirstOrDefault().ToString();
   dynamic tableName = tableNameAttribute.Substring(tableNameAttribute.LastIndexOf('.'), tableNameAttribute.LastIndexOf('\\'));    
}

To populate the column during insert, use a DEFAULT value:

CREATE TABLE users (
  id serial not null,
  firstname varchar(100),
  middlename varchar(100),
  lastname varchar(100),
  email varchar(200),
  timestamp timestamp default current_timestamp
)

Note that the value for that column can explicitly be overwritten by supplying a value in the INSERT statement. If you want to prevent that you do need a trigger.

You also need a trigger if you need to update that column whenever the row is updated (as mentioned by E.J. Brennan)

Note that using reserved words for column names is usually not a good idea. You should find a different name than timestamp

declare -a arr
echo "-------------------------------------"
echo "Here another example with arr numeric"
echo "-------------------------------------"
arr=( 10 200 3000 40000 500000 60 700 8000 90000 100000 )

echo -e "\n Elements in arr are:\n ${arr[0]} \n ${arr[1]} \n ${arr[2]} \n ${arr[3]} \n ${arr[4]} \n ${arr[5]} \n ${arr[6]} \n ${arr[7]} \n ${arr[8]} \n ${arr[9]}"

echo -e " \n Total elements in arr are : ${arr[*]} \n"

echo -e " \n Total lenght of arr is : ${#arr[@]} \n"

for (( i=0; i<10; i++ ))
do      echo "The value in position $i for arr is [ ${arr[i]} ]"
done

for (( j=0; j<10; j++ ))
do      echo "The length in element $j is ${#arr[j]}"
done

for z in "${!arr[@]}"
do      echo "The key ID is $z"
done
~

You could use

os.path.abspath(path_with_backlash)

it returns the path with \

What everyone seems to miss is that the semi-colons in JavaScript are not statement terminators but statement separators. It's a subtle difference, but it is important to the way the parser is programmed. Treat them like what they are and you will find leaving them out will feel much more natural.

I've programmed in other languages where the semi-colon is a statement separator and also optional as the parser does 'semi-colon insertion' on newlines where it does not break the grammar. So I was not unfamiliar with it when I found it in JavaScript.

I don't like noise in a language (which is one reason I'm bad at Perl) and semi-colons are noise in JavaScript. So I omit them.

Have you made sure that the folder "c:\teste" exists? If it doesn't, explorer will open showing some default folder (in my case "C:\Users\[user name]\Documents").

Update

I have tried the following variations:

// opens the folder in explorer
Process.Start(@"c:\temp");
// opens the folder in explorer
Process.Start("explorer.exe", @"c:\temp");
// throws exception
Process.Start(@"c:\does_not_exist");
// opens explorer, showing some other folder)
Process.Start("explorer.exe", @"c:\does_not_exist");

If none of these (well, except the one that throws an exception) work on your computer, I don't think that the problem lies in the code, but in the environment. If that is the case, I would try one (or both) of the following:

• Open the Run dialog, enter "explorer.exe" and hit enter
• Open a command prompt, type "explorer.exe" and hit enter

rules: {
    cname: {
        required: true,
        minlength: 2
    }
},
messages: {
    cname: {
        required: "<li>Please enter a name.</li>",
        minlength: "<li>Your name is not long enough.</li>"
    }
}

webView.setWebChromeClient(new WebChromeClient() {
    @Override
    public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
        return super.onJsAlert(view, url, message, result);
    }
});

Unless you want to insert different dates than "today", you can use CURDATE():

$sql = 'INSERT INTO data_tables (title, date_of_event) VALUES ("%s", CURDATE())';
$sql = sprintf ($sql, $_POST['post_title']);

PS! Please do not forget to sanitize your MySQL input, especially via mysql_real_escape_string ()

#include<bits/stdc++.h>
using namespace std;

int main()
{
int x,n;
cin>>x;
vector<int> v;

cout<<"Enter numbers:\n";

for(int i=0;i<x;i++)
 {
  cin>>n;
  v.push_back(n);
 }


//displaying vector contents

 for(int p : v)
 cout<<p<<" ";
}

A simple way to take input in vector.

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

You can indeed use __call() in a generic fashion to access protected methods. To be able to test this class

class Example {
    protected function getMessage() {
        return 'hello';
    }
}

you create a subclass in ExampleTest.php:

class ExampleExposed extends Example {
    public function __call($method, array $args = array()) {
        if (!method_exists($this, $method))
            throw new BadMethodCallException("method '$method' does not exist");
        return call_user_func_array(array($this, $method), $args);
    }
}

Note that the __call() method does not reference the class in any way so you can copy the above for each class with protected methods you want to test and just change the class declaration. You may be able to place this function in a common base class, but I haven't tried it.

Now the test case itself only differs in where you construct the object to be tested, swapping in ExampleExposed for Example.

class ExampleTest extends PHPUnit_Framework_TestCase {
    function testGetMessage() {
        $fixture = new ExampleExposed();
        self::assertEquals('hello', $fixture->getMessage());
    }
}

I believe PHP 5.3 allows you to use reflection to change the accessibility of methods directly, but I assume you'd have to do so for each method individually.

You have two objects both named bank_holiday -- one a list and one a function. Disambiguate the two.

bank_holiday[month] is raising an error because Python thinks bank_holiday refers to the function (the last object bound to the name bank_holiday), whereas you probably intend it to mean the list.

Let's discuss why an "object not found" error can be thrown in R in addition to explaining what it means. What it means (to many) is obvious: the variable in question, at least according to the R interpreter, has not yet been defined, but if you see your object in your code there can be multiple reasons for why this is happening:

1. check syntax of your declarations. If you mis-typed even one letter or used upper case instead of lower case in a later calling statement, then it won't match your original declaration and this error will occur.

2. Are you getting this error in a notebook or markdown document? You may simply need to re-run an earlier cell that has your declarations before running the current cell where you are calling the variable.

3. Are you trying to knit your R document and the variable works find when you run the cells but not when you knit the cells? If so - then you want to examine the snippet I am providing below for a possible side effect that triggers this error:

   {r sourceDataProb1, echo=F, eval=F} # some code here

The above snippet is from the beginning of an R markdown cell. If eval and echo are both set to False this can trigger an error when you try to knit the document. To clarify. I had a use case where I had left these flags as False because I thought i did not want my code echoed or its results to show in the markdown HTML I was generating. But since the variable was then used in later cells, this caused an error during knitting. Simple trial and error with T/F TRUE/FALSE flags can establish if this is the source of your error when it occurs in knitting an R markdown document from RStudio.

Lastly: did you remove the variable or clear it from memory after declaring it?

• rm() removes the variable
• hitting the broom icon in the evironment window of RStudio clearls everything in the current working environment
• ls() can help you see what is active right now to look for a missing declaration.
• exists("x") - as mentioned by another poster, can help you test a specific value in an environment with a very lengthy list of active variables

what isn't working about it? here's a tested version:

String.prototype.isValidDate = function()   {

    const match = this.match(/^([0-9]{2})\/([0-9]{2})\/([0-9]{4})$/);
    if (!match || match.length !== 4) {
        return false
    }

    const test = new Date(match[3], match[1] - 1, match[2]);

    return (
        (test.getMonth() == match[1] - 1) &&
        (test.getDate() == match[2]) &&
        (test.getFullYear() == match[3])
    );
}

var date = '12/08/1984'; // Date() is 'Sat Dec 08 1984 00:00:00 GMT-0800 (PST)'
alert(date.isValidDate() ); // true

I think in older version of git, you should commit at least one file first, and then you can "push origin master" once again.

Get-ChildItem "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv"

Why not:

public static double log2(int n)
{
    return (Math.log(n) / Math.log(2));
}

I can elaborate on the details of DLLs in Windows to help clarify those mysteries to my friends here in *NIX-land...

A DLL is like a Shared Object file. Both are images, ready to load into memory by the program loader of the respective OS. The images are accompanied by various bits of metadata to help linkers and loaders make the necessary associations and use the library of code.

Windows DLLs have an export table. The exports can be by name, or by table position (numeric). The latter method is considered "old school" and is much more fragile -- rebuilding the DLL and changing the position of a function in the table will end in disaster, whereas there is no real issue if linking of entry points is by name. So, forget that as an issue, but just be aware it's there if you work with "dinosaur" code such as 3rd-party vendor libs.

Windows DLLs are built by compiling and linking, just as you would for an EXE (executable application), but the DLL is meant to not stand alone, just like an SO is meant to be used by an application, either via dynamic loading, or by link-time binding (the reference to the SO is embedded in the application binary's metadata, and the OS program loader will auto-load the referenced SO's). DLLs can reference other DLLs, just as SOs can reference other SOs.

In Windows, DLLs will make available only specific entry points. These are called "exports". The developer can either use a special compiler keyword to make a symbol an externally-visible (to other linkers and the dynamic loader), or the exports can be listed in a module-definition file which is used at link time when the DLL itself is being created. The modern practice is to decorate the function definition with the keyword to export the symbol name. It is also possible to create header files with keywords which will declare that symbol as one to be imported from a DLL outside the current compilation unit. Look up the keywords __declspec(dllexport) and __declspec(dllimport) for more information.

One of the interesting features of DLLs is that they can declare a standard "upon load/unload" handler function. Whenever the DLL is loaded or unloaded, the DLL can perform some initialization or cleanup, as the case may be. This maps nicely into having a DLL as an object-oriented resource manager, such as a device driver or shared object interface.

When a developer wants to use an already-built DLL, she must either reference an "export library" (*.LIB) created by the DLL developer when she created the DLL, or she must explicitly load the DLL at run time and request the entry point address by name via the LoadLibrary() and GetProcAddress() mechanisms. Most of the time, linking against a LIB file (which simply contains the linker metadata for the DLL's exported entry points) is the way DLLs get used. Dynamic loading is reserved typically for implementing "polymorphism" or "runtime configurability" in program behaviors (accessing add-ons or later-defined functionality, aka "plugins").

The Windows way of doing things can cause some confusion at times; the system uses the .LIB extension to refer to both normal static libraries (archives, like POSIX *.a files) and to the "export stub" libraries needed to bind an application to a DLL at link time. So, one should always look to see if a *.LIB file has a same-named *.DLL file; if not, chances are good that *.LIB file is a static library archive, and not export binding metadata for a DLL.

Be sure to configure the 'default' key in app/config/database.php

For postgres, this would be 'default' => 'postgres',

If you are receiving a [PDOException] could not find driver error, check to see if you have the correct PHP extensions installed. You need pdo_pgsql.so and pgsql.so installed and enabled. Instructions on how to do this vary between operating systems.

For Windows, the pgsql extensions should come pre-downloaded with the official PHP distribution. Just edit your php.ini and uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so

Also, in php.ini, make sure extension_dir is set to the proper directory. It should be a folder called extensions or ext or similar inside your PHP install directory.

Finally, copy libpq.dll from C:\wamp\bin\php\php5.*\ into C:\wamp\bin\apache*\bin and restart all services through the WampServer interface.

If you still get the exception, you may need to add the postgres \bin directory to your PATH:

1. System Properties -> Advanced tab -> Environment Variables
2. In 'System variables' group on lower half of window, scroll through and find the PATH entry.
3. Select it and click Edit
4. At the end of the existing entry, put the full path to your postgres bin directory. The bin folder should be located in the root of your postgres installation directory.
5. Restart any open command prompts, or to be certain, restart your computer.

This should hopefully resolve any problems. For more information see:

• http://php.net/manual/en/install.pecl.windows.php
• http://webcheatsheet.com/php/install_and_configure.php#extsetup

Here's how to do it with an HTML Blob, so that you have control over the entire HTML document:

https://codepen.io/trusktr/pen/mdeQbKG?editors=0010

This is the code, but StackOverflow blocks the window from being opened (see the codepen example instead):

const winHtml = `<!DOCTYPE html>_x000D_
    <html>_x000D_
        <head>_x000D_
            <title>Window with Blob</title>_x000D_
        </head>_x000D_
        <body>_x000D_
            <h1>Hello from the new window!</h1>_x000D_
        </body>_x000D_
    </html>`;_x000D_
_x000D_
const winUrl = URL.createObjectURL(_x000D_
    new Blob([winHtml], { type: "text/html" })_x000D_
);_x000D_
_x000D_
const win = window.open(_x000D_
    winUrl,_x000D_
    "win",_x000D_
    `width=800,height=400,screenX=200,screenY=200`_x000D_
);

I'm not using IIS Express but developing against my Local Full IIS 7.

So if anyone else get's here trying to do that, I had to add the mime type for woff via IIS Manager

Mime Types >> Click Add link on right and then enter Extension: .woff MIME type: application/font-woff

Try this,

int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
  System.out.println("Yes option");
} else {
  System.out.println("No Option");
}

I struggled with this, too. Here's what I found. Expanding on Adam's answer, here's a bit more detail, including how to encode VP9 with alpha in a Webm container.

First, Here's a CodePen playground you can play with, feel free to use my videos for testing.

        <video width="600" height="100%" autoplay loop muted playsinline>
        <source src="https://rotato.netlify.app/alpha-demo/movie-hevc.mov" type='video/mp4'; codecs="hvc1">
        <source src="https://rotato.netlify.app/alpha-demo/movie-webm.webm" type="video/webm">
        </video>

And here's a full demo page using z-index to layer the transparent video on top and below certain elements. (You can clone the Webflow template)

So, we'll need a Webm movie for Chrome, and an HEVC with Alpha (supported by Safari on all platforms since 2019)

Which browsers are supported?

For Chrome, I've tested successfully on version 30 from 2013. (Caniuse webm doesn't seem to say which webm codec is supported, so I had to try my way). Earlier versions of chrome seem to render a black area.

For Safari, it's simpler: Catalina (2019) or iOS 11 (2019)

Encoding

Depending on which editing app you're using, I recommend exporting the HEVC with Alpha directly.

But many apps don't support the Webm format, especially on Mac, since it's not a part of AVFoundation.

I recommend exporting an intermediate format like ProRes4444 with an alpha channel to not lose too much quality at this step. Once you have that file, making your webm is as simple as

ffmpeg -i "your-movie-in-prores.mov" -c:v libvpx-vp9 movie-webm.webm

See more approaches in this blog post.

From google drive help pages:

To host a webpage with Drive:

1. Open Drive at drive.google.com and select a file.
2. Click the Share button at the top of the page.
3. Click Advanced in the bottom right corner of the sharing box.
4. Click Change....
5. Choose On - Public on the web and click Save.
6. Before closing the sharing box, copy the document ID from the URL in the field below "Link to share". The document ID is a string of uppercase and lowercase letters and numbers between slashes in the URL.
7. Share the URL that looks like "www.googledrive.com/host/[doc id] where [doc id] is replaced by the document ID you copied in step 6.

Anyone can now view your webpage.

If you want to see your image in a website embed the link to pic in your html as usually:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>Example image from Google Drive</title>
    </head>
    <body>
        <h1>Example image from Google Drive</h1>

        <img src="https://www.googledrive.com/host/[doc id]" alt="whatever">

    </body>
</html>

Note:

Beginning August 31st, 2015, web hosting in Google Drive for users and developers will be deprecated. You can continue to use this feature for a period of one year until August 31st, 2016, when we will discontinue serving content via googledrive.com/host/[doc id]. More info

use c methods FILE *fp =fopen("filename","mode"); fclose(fp); mode means a for appending r for reading ,w for writing

   / / using ofstream constructors.
      #include <iostream>
       #include <fstream>  
      std::string input="some text to write"
     std::ofstream outfile ("test.txt");

    outfile <<input << std::endl;

       outfile.close();

All of the existing answers use the deprecated MD5Init(), MD5Update(), and MD5Final().

Instead, use EVP_DigestInit_ex(), EVP_DigestUpdate(), and EVP_DigestFinal_ex(), e.g.

// example.c
//
// gcc example.c -lssl -lcrypto -o example

#include <openssl/evp.h>
#include <stdio.h>
#include <string.h>

void bytes2md5(const char *data, int len, char *md5buf) {
  // Based on https://www.openssl.org/docs/manmaster/man3/EVP_DigestUpdate.html
  EVP_MD_CTX *mdctx = EVP_MD_CTX_new();
  const EVP_MD *md = EVP_md5();
  unsigned char md_value[EVP_MAX_MD_SIZE];
  unsigned int md_len, i;
  EVP_DigestInit_ex(mdctx, md, NULL);
  EVP_DigestUpdate(mdctx, data, len);
  EVP_DigestFinal_ex(mdctx, md_value, &md_len);
  EVP_MD_CTX_free(mdctx);
  for (i = 0; i < md_len; i++) {
    snprintf(&(md5buf[i * 2]), 16 * 2, "%02x", md_value[i]);
  }
}

int main(void) {
  const char *hello = "hello";
  char md5[33]; // 32 characters + null terminator
  bytes2md5(hello, strlen(hello), md5);
  printf("%s\n", md5);
}

On Android 4.4.4, it seems the only way I could stop an alpha fading animation on a View was calling View.animate().cancel() (i.e., calling .cancel() on the View's ViewPropertyAnimator).

Here's the code I'm using for compatibility before and after ICS:

public void stopAnimation(View v) {
    v.clearAnimation();
    if (canCancelAnimation()) {
        v.animate().cancel();
    }
}

... with the method:

/**
 * Returns true if the API level supports canceling existing animations via the
 * ViewPropertyAnimator, and false if it does not
 * @return true if the API level supports canceling existing animations via the
 * ViewPropertyAnimator, and false if it does not
 */
public static boolean canCancelAnimation() {
    return Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH;
}

Here's the animation that I'm stopping:

v.setAlpha(0f);
v.setVisibility(View.VISIBLE);
// Animate the content view to 100% opacity, and clear any animation listener set on the view.
v.animate()
    .alpha(1f)
    .setDuration(animationDuration)
    .setListener(null);

You'll have to create a custom object for that. Your custom object will contain two values:

• a DateTime value
• a TimeZone object

Not sure if there already is a CLR-provided data type that has that, but at least the TimeZone component is already available.

Initially, check the type of compression with the below command: file <file_name> If the output is a Posix compressed file, use the below command to uncompress: tar xvf <file_name>

Here is a simple one"

public class Palindrome {

    public static void main(String [] args){
        Palindrome pn = new Palindrome();

        if(pn.isPalindrome("ABBA")){
            System.out.println("Palindrome");
        } else {
            System.out.println("Not Palindrome");
        }   
    }

    public boolean isPalindrome(String original){
        int i = original.length()-1;
        int j=0;
        while(i > j) {
            if(original.charAt(i) != original.charAt(j)) {
                return false;
            }
            i--;
            j++;
        }
        return true;
    }
}

private static void GrantAccess(string file)
        {
            bool exists = System.IO.Directory.Exists(file);
            if (!exists)
            {
                DirectoryInfo di = System.IO.Directory.CreateDirectory(file);
                Console.WriteLine("The Folder is created Sucessfully");
            }
            else
            {
                Console.WriteLine("The Folder already exists");
            }
            DirectoryInfo dInfo = new DirectoryInfo(file);
            DirectorySecurity dSecurity = dInfo.GetAccessControl();
            dSecurity.AddAccessRule(new FileSystemAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), FileSystemRights.FullControl, InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.NoPropagateInherit, AccessControlType.Allow));
            dInfo.SetAccessControl(dSecurity);

        }

I had the same issue today. My problem was solved my moving META-INF to the resources folder.

.MERGE_MSG.swp is open in your git, you just need to delete this .swp file. In my case I used following command and it worked fine.

rm .MERGE_MSG.swp

In maven the dependencies got included for me when I removed the dependencyManagement xml section and just had dependencies directly under project section

Do simply like below....

HashMap<String,Object> yourHash = new HashMap<String,Object>();
yourHash.put(yourKey+"message","message");
yourHash.put(yourKey+"timestamp",timestamp);
yourHash.put(yourKey+"count ",count);
yourHash.put(yourKey+"version ",version);

typecast the value while getting back. For ex:

    int count = Integer.parseInt(yourHash.get(yourKey+"count"));
//or
int count = Integer.valueOf(yourHash.get(yourKey+"count"));
//or
int count = (Integer)yourHash.get(yourKey+"count"); //or (int)

if you are using the iCheck Jquery use the below code

 $("#CheckBoxId").on('ifChanged', function () {
                alert($(this).val());
            });

What you want is called an associative array. In python these are called dictionaries.

Dictionaries are sometimes found in other languages as “associative memories” or “associative arrays”. Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys.

myDict = {}
myDict["john"] = "johns value"
myDict["jeff"] = "jeffs value"

Alternative way to create the above dict:

myDict = {"john": "johns value", "jeff": "jeffs value"}

Accessing values:

print(myDict["jeff"]) # => "jeffs value"

Getting the keys (in Python v2):

print(myDict.keys()) # => ["john", "jeff"]

In Python 3, you'll get a dict_keys, which is a view and a bit more efficient (see views docs and PEP 3106 for details).

print(myDict.keys()) # => dict_keys(['john', 'jeff']) 

If you want to learn about python dictionary internals, I recommend this ~25 min video presentation: https://www.youtube.com/watch?v=C4Kc8xzcA68. It's called the "The Mighty Dictionary".

UPDATE 11-12-2020

When you use 'com.google.firebase:firebase-messaging:21.0.0' is FirebaseInstanceIdis depreacted now

Now we need to use FirebaseInstallations.getInstance().getToken() and FirebaseMessaging.getInstance().token

SAMPLE CODE

FirebaseInstallations.getInstance().getToken(true).addOnCompleteListener {
            firebaseToken = it.result!!.token
        }

// OR

FirebaseMessaging.getInstance().token.addOnCompleteListener {
            if(it.isComplete){
                firebaseToken = it.result.toString()
                Util.printLog(firebaseToken)
            }
        }

While the marked answer is correct there is a way of achieving this without exceptions. The service is returning Optional<T> of the searched object and this is mapped to HttpStatus.OK if found and to 404 if empty.

@Controller
public class SomeController {

    @RequestMapping.....
    public ResponseEntity<Object> handleCall() {
        return  service.find(param).map(result -> new ResponseEntity<>(result, HttpStatus.OK))
                .orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND));
    }
}

@Service
public class Service{

    public Optional<Object> find(String param){
        if(!found()){
            return Optional.empty();
        }
        ...
        return Optional.of(data); 
    }

}

Just write an extension method to help you out:

public static class Extensions
{
   public static void ForEachWithNull<T>(this IEnumerable<T> source, Action<T> action)
   {
      if(source == null)
      {
         return;
      }

      foreach(var item in source)
      {
         action(item);
      }
   }
}

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

 public static String clobToString(final Clob clob) throws SQLException, IOException {
        try (final Reader reader = clob.getCharacterStream()) {
            try (final StringWriter stringWriter = new StringWriter()) {
                IOUtils.copy(reader, stringWriter);
                return stringWriter.toString();
            }
        }
    }

Didn't see this one here:

@import 'bootstrap/scss/bootstrap.scss';

I just added this line in style.scss In my case i also wanted to override bootstrap variables.

Change the wrapping from "onload" to "No wrap - in <body>"

The function defined has a different scope.

ES6

convert object to map:

const objToMap = (o) => new Map(Object.entries(o));

convert map to object:

const mapToObj = (m) => [...m].reduce( (o,v)=>{ o[v[0]] = v[1]; return o; },{} )

Note: the mapToObj function assumes map keys are strings (will fail otherwise)

A simple class that can wrap a dict, and retrieve based on a key:

class FindKey(dict):
    def get(self, path, default=None):
        keys = path.split(".")
        val = None

        for key in keys:
            if val:
                if isinstance(val, list):
                    val = [v.get(key, default) if v else None for v in val]
                else:
                    val = val.get(key, default)
            else:
                val = dict.get(self, key, default)

            if not val:
                break

        return val

For example:

person = {'person':{'name':{'first':'John'}}}
FindDict(person).get('person.name.first') # == 'John'

If the key doesn't exist, it returns None by default. You can override that using a default= key in the FindDict wrapper -- for example`:

FindDict(person, default='').get('person.name.last') # == doesn't exist, so ''

Using callback plugins, you can have the stdout of your commands output in readable form with the play: gist: human_log.py

Edit for example output:

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

I'm new to Android development and I do this:

1) Create a class:

import android.util.Log;

public final class Debug{
    private Debug (){}

    public static void out (Object msg){
        Log.i ("info", msg.toString ());
    }
}

When you finish the project delete the class.

2) To print a message to the LogCat write:

Debug.out ("something");

3) Create a filter in the LogCat and write "info" in the input "by Log Tag". All your messages will be written here. :)

Tip: Create another filter to filter all errors to debug easily.

print my_string[0:100]

In some cases, Reflection doesn't work properly.

You could use dictionaries, if all item types are the same. For instance, if your items are strings :

Dictionary<string, string> response = JsonConvert.DeserializeObject<Dictionary<string, string>>(item);

Or ints:

Dictionary<string, int> response = JsonConvert.DeserializeObject<Dictionary<string, int>>(item);

see w3schools samples: https://www.w3schools.com/angular/angular_filters.asp https://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_orderby_click

then add the "reverse" flag:

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<body>

<p>Click the table headers to change the sorting order:</p>

<div ng-app="myApp" ng-controller="namesCtrl">

<table border="1" width="100%">
<tr>
<th ng-click="orderByMe('name')">Name</th>
<th ng-click="orderByMe('country')">Country</th>
</tr>
<tr ng-repeat="x in names | orderBy:myOrderBy:reverse">
<td>{{x.name}}</td>
<td>{{x.country}}</td>
</tr>
</table>

</div>

<script>
angular.module('myApp', []).controller('namesCtrl', function($scope) {
    $scope.names = [
        {name:'Jani',country:'Norway'},
        {name:'Carl',country:'Sweden'},
        {name:'Margareth',country:'England'},
        {name:'Hege',country:'Norway'},

        {name:'Birgit',country:'Denmark'},
        {name:'Mary',country:'England'},
        {name:'Kai',country:'Norway'}
        ];

    $scope.reverse=false;
    $scope.orderByMe = function(x) {

        if($scope.myOrderBy == x) {
            $scope.reverse=!$scope.reverse;
        }
        $scope.myOrderBy = x;
    }
});

use the net use command:

net use Z: \\10.0.1.1\DRIVENAME

Edit 1: Also, I believe the password should be simply appended:

net use Z: \\10.0.1.1\DRIVENAME PASSWORD

You can find out more about this command and its arguments via:

net use ?

Edit 2: As Tomalak mentioned in comments, you can later un-map it via

net use Z: \delete

While performance is an issue, I think modern database designs have made it much less of an issue for small files.

Performance aside, it also depends on just how tightly-coupled the data is. If the file contains data that is closely related to the fields of the database, then it conceptually belongs close to it and may be stored in a blob. If it contains information which could potentially relate to multiple records or may have some use outside of the context of the database, then it belongs outside. For example, an image on a web page is fetched on a separate request from the page that links to it, so it may belong outside (depending on the specific design and security considerations).

Our compromise, and I don't promise it's the best, has been to store smallish XML files in the database but images and other files outside it.

try doing:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    card_view:cardElevation="2dp"
    card_view:cardCornerRadius="5dp">

    <FrameLayout
        android:background="#FF0000"
        android:layout_width="4dp"
        android:layout_height="match_parent"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding="16dp"
        android:orientation="vertical">

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Headline"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Title" />

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Body1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Content here" />

    </LinearLayout>

</android.support.v7.widget.CardView>

this removes the padding from the cardview and adds a FrameLayout with a color. You then need to fix the padding in the LinearLayout then for the other fields

Update

If you want to preserve the card corner radius create card_edge.xml in drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#F00" />
    <size android:width="10dp"/>
    <padding android:bottom="0dp" android:left="0dp" android:right="0dp" android:top="0dp"/>
    <corners android:topLeftRadius="5dp" android:bottomLeftRadius="5dp"
        android:topRightRadius="0.1dp" android:bottomRightRadius="0.1dp"/>
</shape>

and in the frame layout use android:background="@drawable/card_edge"

You can use a temporary deletion list:

List<String> keyList = new ArrayList<String>;

for(Map.Entry<String,String> entry : hashTable){
  if(entry.getValue().equals("delete")) // replace with your own check
    keyList.add(entry.getKey());
}

for(String key : keyList){
  hashTable.remove(key);
}

You can find more information about Hashtable methods in the Java API

My need was sort based on date.

So, I used Comparable and it worked easily for me.

public int compareTo(GoogleCalendarBean o) {
    // TODO Auto-generated method stub
    return eventdate.compareTo(o.getEventdate());
}

One restriction with Comparable is that they cannot used for Collections other than List.

Assuming you have Manage Jenkins > Configure Global Security > Enable Security and Jenkins Own User Database checked you would go to:

• Manage Jenkins > Manage Users > Create User

Assign your image to a string. Eg image Now set icon to a fixed size label.

image.setIcon(new javax.swing.ImageIcon(image.getScaledInstance(50,50,WIDTH)));

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)

The best way is to use a List within a List:

List<List<String>> listOfLists = new ArrayList<List<String>>();  

This is an old question, but everybody fails to mention that Enums are actually Serializable and therefore can perfectly be added to an Intent as an extra. Like this:

public enum AwesomeEnum {
  SOMETHING, OTHER;
}

intent.putExtra("AwesomeEnum", AwesomeEnum.SOMETHING);

AwesomeEnum result = (AwesomeEnum) intent.getSerializableExtra("AwesomeEnum");

The suggestion to use static or application-wide variables is a really bad idea. This really couples your activities to a state managing system, and it is hard to maintain, debug and problem bound.

ALTERNATIVES:

A good point was noted by tedzyc about the fact that the solution provided by Oderik gives you an error. However, the alternative offered is a bit cumbersome to use (even using generics).

If you are really worried about the performance of adding the enum to an Intent I propose these alternatives instead:

OPTION 1:

public enum AwesomeEnum {
  SOMETHING, OTHER;
  private static final String name = AwesomeEnum.class.getName();
  public void attachTo(Intent intent) {
    intent.putExtra(name, ordinal());
  }
  public static AwesomeEnum detachFrom(Intent intent) {
    if(!intent.hasExtra(name)) throw new IllegalStateException();
    return values()[intent.getIntExtra(name, -1)];
  }
}

Usage:

// Sender usage
AwesomeEnum.SOMETHING.attachTo(intent);
// Receiver usage
AwesomeEnum result = AwesomeEnum.detachFrom(intent);

OPTION 2: (generic, reusable and decoupled from the enum)

public final class EnumUtil {
    public static class Serializer<T extends Enum<T>> extends Deserializer<T> {
        private T victim;
        @SuppressWarnings("unchecked") 
        public Serializer(T victim) {
            super((Class<T>) victim.getClass());
            this.victim = victim;
        }
        public void to(Intent intent) {
            intent.putExtra(name, victim.ordinal());
        }
    }
    public static class Deserializer<T extends Enum<T>> {
        protected Class<T> victimType;
        protected String name;
        public Deserializer(Class<T> victimType) {
            this.victimType = victimType;
            this.name = victimType.getName();
        }
        public T from(Intent intent) {
            if (!intent.hasExtra(name)) throw new IllegalStateException();
            return victimType.getEnumConstants()[intent.getIntExtra(name, -1)];
        }
    }
    public static <T extends Enum<T>> Deserializer<T> deserialize(Class<T> victim) {
        return new Deserializer<T>(victim);
    }
    public static <T extends Enum<T>> Serializer<T> serialize(T victim) {
        return new Serializer<T>(victim);
    }
}

Usage:

// Sender usage
EnumUtil.serialize(AwesomeEnum.Something).to(intent);
// Receiver usage
AwesomeEnum result = 
EnumUtil.deserialize(AwesomeEnum.class).from(intent);

OPTION 3 (with Kotlin):

It's been a while, but since now we have Kotlin, I thought I would add another option for the new paradigm. Here we can make use of extension functions and reified types (which retains the type when compiling).

inline fun <reified T : Enum<T>> Intent.putExtra(victim: T): Intent =
    putExtra(T::class.java.name, victim.ordinal)

inline fun <reified T: Enum<T>> Intent.getEnumExtra(): T? =
    getIntExtra(T::class.java.name, -1)
        .takeUnless { it == -1 }
        ?.let { T::class.java.enumConstants[it] }

There are a few benefits of doing it this way.

• We don't require the "overhead" of an intermediary object to do the serialization as it's all done in place thanks to inline which will replace the calls with the code inside the function.
• The functions are more familiar as they are similar to the SDK ones.
• The IDE will autocomplete these functions which means there is no need to have previous knowledge of the utility class.

One of the downsides is that, if we change the order of the Emums, then any old reference will not work. This can be an issue with things like Intents inside pending intents as they may survive updates. However, for the rest of the time, it should be ok.

It's important to note that other solutions, like using the name instead of the position, will also fail if we rename any of the values. Although, in those cases, we get an exception instead of the incorrect Enum value.

Usage:

// Sender usage
intent.putExtra(AwesomeEnum.SOMETHING)
// Receiver usage
val result = intent.getEnumExtra<AwesomeEnum>()

I had the same problem and I did it this way

//note that I added jquery separately above this

<!--ENJOY HINT PACKAGES --START -->
<link href="path/enjoyhint/jquery.enjoyhint.css" rel="stylesheet">
<script src="path/enjoyhint/jquery.enjoyhint.js"></script>
<script src="path/enjoyhint/kinetic.min.js"></script>
<script src="path/enjoyhint/enjoyhint.js"></script>  
<!--ENJOY HINT PACKAGES --END -->

and it works

join this "literal table",

select 
    t.c.value('@c', 'varchar(30)') code,
    t.c.value('@v', 'varchar(30)') val
from (select convert(xml, '<x c="CODE001" v="Value One" /><x c="CODE002" v="Value Two" />') aXmlCol) z
cross apply aXmlCol.nodes('/x') t(c)

You can use the following:

Request.Params["paramName"]

See also: When do Request.Params and Request.Form differ?

That's a lot of questions.

1. Why EOF is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"

2. any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF is 0 when it's FALSE, meaning getchar() returned EOF.

3. in order to emulate EOF when reading from stdin press Ctrl+D

Runas.exe won't work here. You can use VBScript to invoke the "Run as Administrator" shell verb. The Elevation Powertoys contain a batchfile that allows you to invoke an elevated command:

elevatecmd.exe

http://blogs.technet.com/b/elevationpowertoys/

Use the __contains__() method of Pythons string class.:

a = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
for i in a:
    if i.__contains__("abc") :
        print(i, " is containing")

If you want each task to run regardless of any failures, you can do something like:

task :build_all do
  [:debug, :release].each do |t| 
    ts = 0
    begin  
      Rake::Task["build"].invoke(t)
    rescue
      ts = 1
      next
    ensure
      Rake::Task["build"].reenable # If you need to reenable
    end
    return ts # Return exit code 1 if any failed, 0 if all success
  end
end

Another option...

To make this works

docker run -d --rm $IMG_NAME "bash:command1&&command2&&command3"

in dockerfile

ENTRYPOINT ["/entrypoint.sh"]

in entrypoint.sh

#!/bin/sh

entrypoint_params=$1
printf "==>[entrypoint.sh] %s\n" "entry_point_param is $entrypoint_params"

PARAM1=$(echo $entrypoint_params | cut -d':' -f1) # output is 1 must be 'bash' it     will be tested    
PARAM2=$(echo $entrypoint_params | cut -d':' -f2) # the real command separated by     &&

printf "==>[entrypoint.sh] %s\n" "PARAM1=$PARAM1"
printf "==>[entrypoint.sh] %s\n" "PARAM2=$PARAM2"

if [ "$PARAM1" = "bash" ];
then
    printf "==>[entrypoint.sh] %s\n" "about to running $PARAM2 command"
    echo $PARAM2 | tr '&&' '\n' | while read cmd; do
        $cmd
    done    
fi

Try using http://www.example.org?candy_name=M%26M.

See also this reference and some more information on Wikipedia.

you can use it directly with $scope instance

     $scope.init=function()
        {
            console.log("entered");
            data={};
            /*do whatever you want such as initialising scope variable,
              using $http instance etcc..*/
        }
       //simple call init function on controller
       $scope.init();

See strtotime()

strtotime('next tuesday');

You could probably find out if you have gone past that day by looking at the week number:

$nextTuesday = strtotime('next tuesday');
$weekNo = date('W');
$weekNoNextTuesday = date('W', $nextTuesday);

if ($weekNoNextTuesday != $weekNo) {
    //past tuesday
}

<button type="submit" name="uname" value="uname" onclick="browserlink(ex.google.com,home.html etc)or myfunction();"> submit</button>

if you want to open a page on the click of a button in HTML without any scripting language then you can use above code.

Basically this is what you need to do:
in the first activity:

Intent intent = new Intent();
intent.setAction(this, SecondActivity.class);
intent.putExtra(tag, value);
startActivity(intent);

and in the second activtiy:

Intent intent = getIntent();
intent.getBooleanExtra(tag, defaultValue);
intent.getStringExtra(tag, defaultValue);
intent.getIntegerExtra(tag, defaultValue);

one of the get-functions will give return you the value, depending on the datatype you are passing through.

Try

import sys
print(sys.version)

This prints the full version information string. If you only want the python version number, then Bastien Léonard's solution is the best. You might want to examine the full string and see if you need it or portions of it.

create layout dynamically and set its parameter as setmargin() will not work directly on an imageView

ImageView im;
im = (ImageView) findViewById(R.id.your_image_in_XML_by_id);
 RelativeLayout.LayoutParams layout = new RelativeLayout.LayoutParams(im.getLayoutParams());
                        layout.setMargins(counter*27, 0, 0, 0);//left,right,top,bottom
                        im.setLayoutParams(layout);
                        im.setImageResource(R.drawable.yourimage)

If you are using python 2.7 or later, the easiest way to do this is to use the subprocess.check_output() command. Here is an example:

output = subprocess.check_output('ls')

To also redirect stderr you can use the following:

output = subprocess.check_output('ls', stderr=subprocess.STDOUT)

In the case that you want to pass parameters to the command, you can either use a list or use invoke a shell and use a single string.

output = subprocess.check_output(['ls', '-a'])
output = subprocess.check_output('ls -a', shell=True)

Here is something:

char const hex_chars[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };

for( int i = data; i < data_length; ++i )
{
    char const byte = data[i];

    string += hex_chars[ ( byte & 0xF0 ) >> 4 ];
    string += hex_chars[ ( byte & 0x0F ) >> 0 ];
}

This one works with copy and paste, drag and drop, key down, prevents overflow and is pretty simple

public partial class IntegerBox : TextBox 
{
    public IntegerBox()
    {
        InitializeComponent();
        this.Text = 0.ToString();
    }

    protected override void OnPaint(PaintEventArgs pe)
    {
        base.OnPaint(pe);
    }

    private String originalValue = 0.ToString();

    private void Integerbox_KeyPress(object sender, KeyPressEventArgs e)
    {
        originalValue = this.Text;
    }

    private void Integerbox_TextChanged(object sender, EventArgs e)
    {
        try
        {
            if(String.IsNullOrWhiteSpace(this.Text))
            {
                this.Text = 0.ToString();
            }
            this.Text = Convert.ToInt64(this.Text.Trim()).ToString();
        }
        catch (System.OverflowException)
        {
            MessageBox.Show("Value entered is to large max value: " + Int64.MaxValue.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            this.Text = originalValue;
        }
        catch (System.FormatException)
        {                
            this.Text = originalValue;
        }
        catch (System.Exception ex)
        {
            this.Text = originalValue;
            MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK , MessageBoxIcon.Error);
        }
    }       
}

Yes, Mid.

Dim sub_str
sub_str = Mid(source_str, 10, 5)

The first parameter is the source string, the second is the start index, and the third is the length.

@bobobobo: Note that VBScript strings are 1-based, not 0-based. Passing 0 as an argument to Mid results in "invalid procedure call or argument Mid".

In place reversal with minimum amount of swaps.

for (int i = 0; i < a.length / 2; i++) {
    int tmp = a[i];
    a[i] = a[a.length - 1 - i];
    a[a.length - 1 - i] = tmp;
}

Try adding a semi colon to the end of your structure:

 struct sotrudnik {
    string name;
    string speciality;
    string razread;
    int zarplata;
} //Semi colon here

For python selenium,

Importing the library,

from selenium.webdriver.common.keys import Keys

Use this code to press any key you want,

Anyelement.send_keys(Keys.RETURN)

You can find all the key names by searching this selenium.webdriver.common.keys.

Generators could be thought of as shorthand for creating an iterator. They behave like a Java Iterator. Example:

>>> g = (x for x in range(10))
>>> g
<generator object <genexpr> at 0x7fac1c1e6aa0>
>>> g.next()
0
>>> g.next()
1
>>> g.next()
2
>>> list(g)   # force iterating the rest
[3, 4, 5, 6, 7, 8, 9]
>>> g.next()  # iterator is at the end; calling next again will throw
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

Hope this helps/is what you are looking for.

Update:

As many other answers are showing, there are different ways to create a generator. You can use the parentheses syntax as in my example above, or you can use yield. Another interesting feature is that generators can be "infinite" -- iterators that don't stop:

>>> def infinite_gen():
...     n = 0
...     while True:
...         yield n
...         n = n + 1
... 
>>> g = infinite_gen()
>>> g.next()
0
>>> g.next()
1
>>> g.next()
2
>>> g.next()
3
...

The bootstrap docs says about this:

Requires custom widths Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.

The default width of 100% as all form elements gets when they got the class form-control didn't apply if you use the form-inline class on your form.

You could take a look at the bootstrap.css (or .less, whatever you prefer) where you will find this part:

.form-inline {

  // Kick in the inline
  @media (min-width: @screen-sm-min) {
    // Inline-block all the things for "inline"
    .form-group {
      display: inline-block;
      margin-bottom: 0;
      vertical-align: middle;
    }

    // In navbar-form, allow folks to *not* use `.form-group`
    .form-control {
      display: inline-block;
      width: auto; // Prevent labels from stacking above inputs in `.form-group`
      vertical-align: middle;
    }
    // Input groups need that 100% width though
    .input-group > .form-control {
      width: 100%;
    }

    [...]
  }
}

Maybe you should take a look at input-groups, since I guess they have exactly the markup you want to use (working fiddle here):

<div class="row">
   <div class="col-lg-12">
    <div class="input-group input-group-lg">
      <input type="text" class="form-control input-lg" id="search-church" placeholder="Your location (City, State, ZIP)">
      <span class="input-group-btn">
        <button class="btn btn-default btn-lg" type="submit">Search</button>

You suggested "Catching any unexpected errors and return some error code signaling "unexpected situation" " but couldn't find an appropriate error code.

Guess what: That's what 5xx is there for.

You can use plenty of things.

• If you're a standards junkie, you can use the HTML5 <audio> tag:

Here is the official W3C specification for the audio tag.

Usage:

<audio controls>
 <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.mp4"
         type='audio/mp4'>
 <!-- The next two lines are only executed if the browser doesn't support MP4 files -->
 <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.oga"
         type='audio/ogg; codecs=vorbis'>
 <!-- The next line will only be executed if the browser doesn't support the <audio> tag-->
 <p>Your user agent does not support the HTML5 Audio element.</p>
</audio>

jsFiddle here.

• Or, if you want to support older browsers, you can use many of the free audio flash players available. Such as:

  • Dewplayer
  • MP3 Player (boring name... right? :) )
  • Website Music Player (even more boring... right?)
  • Zanorg Player

Note: I'm not sure which are the best ones, as I have never used one (yet).

UPDATE: As mentioned in another answer's comment, you are using XHTML 1.0 Transitional. You might be able to get <audio> to work with some hack.

UPDATE 2: I just remembered another way to do play audio. This will work in XHTML!!! This is fully standards-compliant.

You use this JavaScript:

var aud = document.createElement("iframe");
aud.setAttribute('src', "http://yoursite.com/youraudio.mp4"); // replace with actual file path
aud.setAttribute('width', '1px');
aud.setAttribute('height', '1px');
aud.setAttribute('scrolling', 'no');
aud.style.border = "0px";
document.body.appendChild(aud);

This is my answer to another question.

UPDATE 3: To customise the controls, you can use something like this.

First, you need to do:

git fetch # If you don't know about branch name

git fetch origin branch_name

Second, you can check out remote branch into your local by:

git checkout -b branch_name origin/branch_name

-b will create new branch in specified name from your selected remote branch.

I noticed "[" indexing columns fails to create levels when iterating:

for ( a_feature in convert.to.factors) {
feature.df[a_feature] <- factor(feature.df[a_feature]) }

It creates, e.g. for the "Status" column:

Status : Factor w/ 1 level "c(\"Success\", \"Fail\")" : NA NA NA ...

Which is remedied by using "[[" indexing:

for ( a_feature in convert.to.factors) {
feature.df[[a_feature]] <- factor(feature.df[[a_feature]]) }

Giving instead, as desired:

. Status : Factor w/ 2 levels "Success", "Fail" : 1 1 2 1 ...

I use CTRL-SHIFT-DELETE which activates the privacy feature, allowing you to clear your cache, reset cookies, etc, all at once. You can even configure it so that it just DOES it, instead of popping up a dialog box asking you to confirm.

Give an ID to your span and then change the text of target span.

$("#StatusTitle").text("Info");
$("#StatusTitleIcon").removeClass("fa-exclamation").addClass("fa-info-circle"); 

<i id="StatusTitleIcon" class="fa fa-exclamation fa-fw"></i>
<span id="StatusTitle">Error</span>

Here "Error" text will become "Info" and their fontawesome icons will be changed as well.

In my case (I'm using typescript) I was trying to simulate response with fake data where the data is assigned later on. My first attempt was with:

let response = {status: 200, data: []};

and later, on the assignment of the fake data it starts complaining that it is not assignable to type 'never[]'. Then I defined the response like follows and it accepted it..

let dataArr: MyClass[] = [];
let response = {status: 200, data: dataArr};

and assigning of the fake data:

response.data = fakeData;

To make it simple I will take the two versions of the code in keras and tf.keras. The example here is a simple Neural Network Model with different layers in it.

In Keras (v2.1.5)

from keras.models import Sequential
from keras.layers import Dense

def get_model(n_x, n_h1, n_h2):
    model = Sequential()
    model.add(Dense(n_h1, input_dim=n_x, activation='relu'))
    model.add(Dense(n_h2, activation='relu'))
    model.add(Dropout(0.5))
    model.add(Dense(4, activation='softmax'))
    model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
    print(model.summary())
    return model

In tf.keras (v1.9)

import tensorflow as tf

def get_model(n_x, n_h1, n_h2):
    model = tf.keras.Sequential()
    model.add(tf.keras.layers.Dense(n_h1, input_dim=n_x, activation='relu'))
    model.add(tf.keras.layers.Dense(n_h2, activation='relu'))
    model.add(tf.keras.layers.Dropout(0.5))
    model.add(tf.keras.layers.Dense(4, activation='softmax'))
    model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
    print(model.summary())

    return model

or it can be imported the following way instead of the above-mentioned way

from tensorflow.keras.layers import Dense

The official documentation of tf.keras

Note: TensorFlow Version is 1.9

Uninstalling pycparser:

pip uninstall pycparser

Reinstall pycparser:

pip install pycparser

I got same error while installing termcolor and I fixed it by reinstalling it .

Servlet-mapping has two child tags, url-pattern and servlet-name. url-pattern specifies the type of urls for which, the servlet given in servlet-name should be called. Be aware that, the container will use case-sensitive for string comparisons for servlet matching.

First specification of url-pattern a web.xml file for the server context on the servlet container at server .com matches the pattern in <url-pattern>/status/*</url-pattern> as follows:

http://server.com/server/status/synopsis               = Matches
http://server.com/server/status/complete?date=today    = Matches
http://server.com/server/status                        = Matches
http://server.com/server/server1/status                = Does not match

Second specification of url-pattern A context located at the path /examples on the Agent at example.com matches the pattern in <url-pattern>*.map</url-pattern> as follows:

 http://server.com/server/US/Oregon/Portland.map    = Matches
 http://server.com/server/US/server/Seattle.map     = Matches
 http://server.com/server/Paris.France.map          = Matches
 http://server.com/server/US/Oregon/Portland.MAP    = Does not match, the extension is uppercase
 http://example.com/examples/interface/description/mail.mapi  =Does not match, the extension is mapi rather than map`

Third specification of url-mapping,A mapping that contains the pattern <url-pattern>/</url-pattern> matches a request if no other pattern matches. This is the default mapping. The servlet mapped to this pattern is called the default servlet.

The default mapping is often directed to the first page of an application. Explicitly providing a default mapping also ensures that malformed URL requests into the application return are handled by the application rather than returning an error.

The servlet-mapping element below maps the server servlet instance to the default mapping.

<servlet-mapping>
  <servlet-name>server</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

For the context that contains this element, any request that is not handled by another mapping is forwarded to the server servlet.

And Most importantly we should Know about Rule for URL path mapping

1. The container will try to find an exact match of the path of the request to the path of the servlet. A successful match selects the servlet.
2. The container will recursively try to match the longest path-prefix. This is done by stepping down the path tree a directory at a time, using the ’/’ character as a path separator. The longest match determines the servlet selected.
3. If the last segment in the URL path contains an extension (e.g. .jsp), the servlet container will try to match a servlet that handles requests for the extension. An extension is defined as the part of the last segment after the last ’.’ character.
4. If neither of the previous three rules result in a servlet match, the container will attempt to serve content appropriate for the resource requested. If a “default” servlet is defined for the application, it will be used.

Reference URL Pattern

Recently I was also having this issue, then I contacted Google Support and they gave me this link to provide required info, I posted and within 24 hours my problem was fixed.

Yep, why not?

fs.Write(myByteArray, 0, myByteArray.Length);

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

Solution for EF4.3

Unique UserName

Add data annotation over column as:

 [Index(IsUnique = true)]
 [MaxLength(255)] // for code-first implementations
 public string UserName{get;set;}

Unique ID , I have added decoration [Key] over my column and done. Same solution as described here: https://msdn.microsoft.com/en-gb/data/jj591583.aspx

IE:

[Key]
public int UserId{get;set;}

Alternative answers

using data annotation

[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Column("UserId")]

using mapping

  mb.Entity<User>()
            .HasKey(i => i.UserId);
        mb.User<User>()
          .Property(i => i.UserId)

On windows forms it is available, at the top of the class put

  static void Main(string[] args)
    {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
       //other stuff here
    }

since windows is single threaded, its all you need, in the event its a service you need to put it right above the call to the service (since there is no telling what thread you'll be on).

using System.Security.Principal 

is also needed.

You could do this by creating a reverse (collapse) animation with clip-path.

    100% {_x000D_

If you want to see the first 10 lines you can use sed as below:

sed -n '1,10 p' myFile.txt

Or if you want to see lines from 20 to 30 you can use:

sed -n '20,30 p' myFile.txt

spam = 'have a nice day'
var = 'd'


def count(spam, var):
    found = 0
    for key in spam:
        if key == var:
            found += 1
    return found
count(spam, var)
print 'count %s is: %s ' %(var, count(spam, var))

In javascript that uses the CommonJS spec, like node.js for instance you can do what I show below. Which is pretty handy for accessing a variable by a string even if its not defined on the window object. If there is a class named MyClass, defined within a CommonJS module named MyClass.js

// MyClass.js
var MyClass = function() {
    // I do stuff in here. Probably return an object
    return {
       foo: "bar"
    }
}

module.exports = MyClass;

You can then do this nice bit o witchcraft from another file called MyOtherFile.js

// MyOtherFile.js

var myString = "MyClass";

var MyClass = require('./' + myString);
var obj = new MyClass();

console.log(obj.foo); // returns "bar"

One more reason why CommonJS is such a pleasure.

You can try like this:

SELECT PARSENAME('$'+ Convert(varchar,Convert(money,@MoneyValue),1),2)

If you run this php artisan config:cache command on console then it will store all the .env file contents in cache, after this command if you append any contents into .env file the it will not be not be available until you run php artisan config:clear command

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

You could create your key object something like this:

public class MapKey {

public  Object key1;
public Object key2;

public Object getKey1() {
    return key1;
}

public void setKey1(Object key1) {
    this.key1 = key1;
}

public Object getKey2() {
    return key2;
}

public void setKey2(Object key2) {
    this.key2 = key2;
}

public boolean equals(Object keyObject){

    if(keyObject==null)
        return false;

    if (keyObject.getClass()!= MapKey.class)
        return false;

    MapKey key = (MapKey)keyObject;

    if(key.key1!=null && this.key1==null)
        return false;

    if(key.key2 !=null && this.key2==null)
        return false;

    if(this.key1==null && key.key1 !=null)
        return false;

    if(this.key2==null && key.key2 !=null)
        return false;

    if(this.key1==null && key.key1==null && this.key2 !=null && key.key2 !=null)
        return this.key2.equals(key.key2);

    if(this.key2==null && key.key2==null && this.key1 !=null && key.key1 !=null)
        return this.key1.equals(key.key1);

    return (this.key1.equals(key.key1) && this.key2.equals(key2));
}

public int hashCode(){
    int key1HashCode=key1.hashCode();
    int key2HashCode=key2.hashCode();
    return key1HashCode >> 3 + key2HashCode << 5;
}

}

The advantage of this is: It will always make sure you are covering all the scenario's of Equals as well.

NOTE: Your key1 and key2 should be immutable. Only then will you be able to construct a stable key Object.

• Update the Android SDK to latest version

• Update app/build.gradle with latest components:

  compileSdkVersion 25  
  buildToolsVersion "25.0.2"  
  minSdkVersion 17  
  targetSdkVersion 25
  

Hope this solves your problem

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

Unfortunately DEBUG is overloaded heavily. For instance, it's recommended to always generate and save a pdb file for RELEASE builds. Which means one of the -Zx flags, and -DEBUG linker option. While _DEBUG relates to special debug versions of runtime library such as calls to malloc and free. Then NDEBUG will disable assertions.

Bundles are generally used for passing data between various Android activities. It depends on you what type of values you want to pass, but bundles can hold all types of values and pass them to the new activity.

You can use it like this:

Intent intent = new...
Intent(getApplicationContext(), SecondActivity.class);
intent.putExtra("myKey", AnyValue);  
startActivity(intent);

You can get the passed values by doing:

Bundle extras = intent.getExtras(); 
String tmp = extras.getString("myKey");

You can find more info at:

• android-using-bundle-for-sharing-variables and

• Passing-Bundles-Around-Activities

This is the easiest way to check the size

let img = new Image()
img.src = window.URL.createObjectURL(event.target.files[0])
img.onload = () => {
   alert(img.width + " " + img.height);
}

Check for specific size. Using 100 x 100 as example

let img = new Image()
img.src = window.URL.createObjectURL(event.target.files[0])
img.onload = () => {
   if(img.width === 100 && img.height === 100){
        alert(`Nice, image is the right size. It can be uploaded`)
        // upload logic here
        } else {
        alert(`Sorry, this image doesn't look like the size we wanted. It's 
   ${img.width} x ${img.height} but we require 100 x 100 size image.`);
   }                
}

Here is an example of using Bootstrap's Button via React-Bootstrap (version 0.32.4):

var condition = true;

return (
  <Button {...(condition ? {bsStyle: 'success'} : {})} />
);

Depending on the condition, either {bsStyle: 'success'} or {} will be returned. The spread operator will then spread the properties of the returned object to Button component. In the falsy case, since no properties exist on the returned object, nothing will be passed to the component.

An alternative way based on Andy Polhill's comment:

var condition = true;

return (
  <Button bsStyle={condition ? 'success' : undefined} />
);

The only small difference is that in the second example the inner component <Button/>'s props object will have a key bsStyle with a value of undefined.

We have had the same issue in eclipse or intellij. After trying many alternative solutions, I found simple solution - add this config to your application.properties: spring.main.web-application-type=none

As was stated in the comments to the original post, this seemed to be an issue with the python interpreter I was using for whatever reason, and not something wrong with the python scripts. I switched over from the WinPython bundle to the official python 3.6 from python.org and it worked just fine. thanks for the help everyone :)

i prefer to use ng-value with ng-if, [ng-value] will handle trigger changes

<input type="radio"  name="isStudent" ng-model="isStudent" ng-value="true" />

//to show and hide input by removing it from the DOM, that's make me secure from malicious data

<input type="text" ng-if="isStudent"  name="textForStudent" ng-model="job">

i also faced similar issue. I could able to solve this by setting JAVA_HOME in Environment variable in windows. Setting JAVA_HOME in batch file is not working in this case.

If you are using an in-memory collection as your filter, it's probably best to use the negation of Contains(). Note that this can fail if the list is too long, in which case you will need to choose another strategy (see below for using a strategy for a fully DB-oriented query).

   var exceptionList = new List<string> { "exception1", "exception2" };

   var query = myEntities.MyEntity
                         .Select(e => e.Name)
                         .Where(e => !exceptionList.Contains(e.Name));

If you're excluding based on another database query using Except might be a better choice. (Here is a link to the supported Set extensions in LINQ to Entities)

   var exceptionList = myEntities.MyOtherEntity
                                 .Select(e => e.Name);

   var query = myEntities.MyEntity
                         .Select(e => e.Name)
                         .Except(exceptionList);

This assumes a complex entity in which you are excluding certain ones depending some property of another table and want the names of the entities that are not excluded. If you wanted the entire entity, then you'd need to construct the exceptions as instances of the entity class such that they would satisfy the default equality operator (see docs).

If the types can be directly cast this is the cleanest way to do it:

var target = yourList.ConvertAll(x => (TargetType)x);

If the types can't be directly cast then you can map the properties from the orginal type to the target type.

var target = yourList.ConvertAll(x => new TargetType { SomeValue = x.SomeValue });

The accepted answer to this question is a guide for getting IIS Express to work with webmatrix. I found this guide more useful when trying to get it to work with VS 2010.

I just followed steps 3 & 4 (running IIS Express as administrator) and had to temporarily disable my firewall to get it working.

Latest versions of Excel has a new tool called Slicers. Using slicers in VBA is actually more reliable that .CurrentPage (there have been reports of bugs while looping through numerous filter options). Here is a simple example of how you can select a slicer item (remember to deselect all the non-relevant slicer values):

Sub Step_Thru_SlicerItems2()
Dim slItem As SlicerItem
Dim i As Long
Dim searchName as string

Application.ScreenUpdating = False
searchName="Value1"

    For Each slItem In .VisibleSlicerItems
        If slItem.Name <> .SlicerItems(1).Name Then _
            slItem.Selected = False
        Else
            slItem.Selected = True
        End if
    Next slItem
End Sub

There are also services like SmartKato that would help you out with setting up your dashboards or reports and/or fix your code.

As a general point when using a search engine to search for SQL codes make sure you put the sqlcode e.g. -302 in quote marks - like "-302" otherwise the search engine will exclude all search results including the text 302, since the - sign is used to exclude results.

In case you are using quite popular in Spring Boot environment Kubernetes (K8S) or OpenShift, there's a possibility to store and retrieve application properties on runtime. This technique called secrets. In your configuration yaml file for Kubernetes or OpenShift you declare variable and placeholder for it, and on K8S\OpenShift side declare actual value which corresponds to this placeholder. For implementation details, see: K8S: https://kubernetes.io/docs/concepts/configuration/secret/ OpenShift: https://docs.openshift.com/container-platform/3.11/dev_guide/secrets.html

Create unique constraint that two numbers together CANNOT together be repeated:

ALTER TABLE someTable
ADD UNIQUE (col1, col2)

I use that and it works :

<!--[if !IE]><!--> if it is not IE <!--<![endif]-->

Lower mm means minutes, so

DateTime.Now.ToString("dd/MM/yyyy");  

or

DateTime.Now.ToString("d");  

or

DateTime.Now.ToShortDateString()

works.

Update 2020:

There are several options available*:

*Disclaimer: This list may not be complete.

Using Flexbox
Nowadays, we can use flexbox. It is quite a handy alternative to the css-transform option. I would use this solution almost always. If it is just one element maybe not, but for example if I had to support an array of data e.g. rows and columns and I want them to be relatively centered in the very middle.

.flexbox {
  display: flex;
  height: 100px;
  flex-flow: row wrap;
  align-items: center;
  justify-content: center;
  background-color: #eaeaea;
  border: 1px dotted #333;
}

.item {
  /* default => flex: 0 1 auto */
  background-color: #fff;
  border: 1px dotted #333;
  box-sizing: border-box;
}

<div class="flexbox">
  <div class="item">I am centered in the middle.</div>
  <div class="item">I am centered in the middle, too.</div>
</div>

Using CSS 2D-Transform
This is still a good option, was also the accepted solution back in 2015. It is very slim and simple to apply and does not mess with the layouting of other elements.

.boxes {
  position: relative;
}

.box {
  position: relative;
  display: inline-block;
  float: left;
  width: 200px;
  height: 200px;
  font-weight: bold;
  color: #333;
  margin-right: 10px;
  margin-bottom: 10px;
  background-color: #eaeaea;
}

.h-center {
  text-align: center;
}

.v-center span {
  position: absolute;
  left: 0;
  right: 0;
  top: 50%;
  transform: translate(0, -50%);
}

<div class="boxes">
  <div class="box h-center">horizontally centered lorem ipsun dolor sit amet</div>
  <div class="box v-center"><span>vertically centered lorem ipsun dolor sit amet lorem ipsun dolor sit amet</span></div>
  <div class="box h-center v-center"><span>horizontally and vertically centered lorem ipsun dolor sit amet</span></div>
</div>

Note: This does also work with :after and :before pseudo-elements.

Using Grid
This might just be an overkill, but it depends on your DOM. If you want to use grid anyway, then why not. It is very powerful alternative and you are really maximum flexible with the design.

Note: To align the items vertically we use flexbox in combination with grid. But we could also use display: grid on the items.

.grid {
  display: grid;
  width: 400px;
  grid-template-rows: 100px;
  grid-template-columns: 100px 100px 100px;
  grid-gap: 3px;
  align-items: center;
  justify-content: center;
  background-color: #eaeaea;
  border: 1px dotted #333;
}

.item {
  display: flex;
  justify-content: center;
  align-items: center;
  border: 1px dotted #333;
  box-sizing: border-box;
}

.item-large {
  height: 80px;
}

<div class="grid">
  <div class="item">Item 1</div>
  <div class="item item-large">Item 2</div>
  <div class="item">Item 3</div>
</div>
