ORA-12154: TNS:could not resolve the connect identifier specified?

In case the TNS is not defined you can also try this one:

If you are using C#.net 2010 or other version of VS and oracle 10g express edition or lower version, and you make a connection string like this:

static string constr = @"Data Source=(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname )(PORT=1521)))
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));
    User Id=system ;Password=yourpasswrd"; 

After that you get error message ORA-12154: TNS:could not resolve the connect identifier specified then first you have to do restart your system and run your project.

And if Your windows is 64 bit then you need to install oracle 11g 32 bit and if you installed 11g 64 bit then you need to Install Oracle 11g Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio version 11.2.0.1.2 or later from OTN and check it in Oracle Universal Installer Please be sure that the following are checked:

Oracle Data Provider for .NET 2.0

Oracle Providers for ASP.NET

Oracle Developer Tools for Visual Studio

Oracle Instant Client 

And then restart your Visual Studio and then run your project .... NOTE:- SYSTEM RESTART IS necessary TO SOLVE THIS TYPES OF ERROR.......

copy paste pl sql developer in program files x86 and program files both. if client is installed in other partition/drive then copy pl sql developer to that drive also. and run from pl sql developer folder instead of desktop shortcut.

ultimate solution ! chill

This is an old question but Oracle's latest installers are no improvement, so I recently found myself back in this swamp, thrashing around for several days ...

My scenario was SQL Server 2016 RTM. 32-bit Oracle 12c Open Client + ODAC was eventually working fine for Visual Studio Report Designer and Integration Services designer, and also SSIS packages run through SQL Server Agent (with 32-bit option). 64-bit was working fine for Report Portal when defining and Testing an Data Source, but running the reports always gave the dreaded "ORA-12154" error.

My final solution was to switch to an EZCONNECT connection string - this avoids the TNSNAMES mess altogether. Here's a link to a detailed description, but it's basically just: host:port/sid

http://www.oracledistilled.com/oracle-database/oracle-net/using-easy-connect-ezconnect-naming-method-to-connect-to-oracle-databases/

In case it helps anyone in the future (or I get stuck on this again), here are my Oracle install steps (the full horror):

Install Oracle drivers: Oracle Client 12c (32-bit) plus ODAC.

a. Download and unzip the following files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html and http://www.oracle.com/technetwork/database/windows/downloads/utilsoft-087491.html ):

i. winnt_12102_client32.zip

ii. ODAC112040Xcopy_32bit.zip

b. Run winnt_12102_client32\client32\setup.exe. For the Installation Type, choose Admin. For the installation location enter C:\Oracle\Oracle12. Accept other defaults.

c. Start a Command Prompt “As Administrator” and change directory (cd) to your ODAC112040Xcopy_32bit folder.

d. Enter the command: install.bat all C:\Oracle\Oracle12 odac

e. Copy the tnsnames.ora file from another machine to these folders: *

i. C:\Oracle\Oracle12\network\admin *

ii. C:\Oracle\Oracle12\product\12.1.0\client_1\network\admin *

Install Oracle Client 12c (x64) plus ODAC

a. Download and unzip the following files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html and http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html ):

i. winx64_12102_client.zip

ii. ODAC121024Xcopy_x64.zip

b. Run winx64_12102_client\client\setup.exe. For the Installation Type, choose Admin. For the installation location enter C:\Oracle\Oracle12_x64. Accept other defaults.

c. Start a Command Prompt “As Administrator” and change directory (cd) to the C:\Software\Oracle Client\ODAC121024Xcopy_x64 folder.

d. Enter the command: install.bat all C:\Oracle\Oracle12_x64 odac

e. Copy the tnsnames.ora file from another machine to these folders: *

i. C:\Oracle\Oracle12_x64\network\admin *

ii. C:\Oracle\Oracle12_x64\product\12.1.0\client_1\network\admin *

* If you are going with the EZCONNECT method, then these steps are not required.

The ODAC installs are tricky and obscure - thanks to Dan English who gave me the method (detailed above) for that.

It has nothing to do with a space embedded in the folder structure.

I had the same problem. But when I created an environmental variable (defined both at the system- and user-level) called TNS_HOME and made it to point to the folder where TNSNAMES.ORA existed, the problem was resolved. Voila!

This is my HelpersProvider.php file:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class HelperServiceProvider extends ServiceProvider
{
    protected $helpers = [
        // Add your helpers in here
    ];

    /**
     * Bootstrap the application services.
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     */
    public function register()
    {
        foreach ($this->helpers as $helper) {
            $helper_path = app_path().'/Helpers/'.$helper.'.php';

            if (\File::isFile($helper_path)) {
                require_once $helper_path;
            }
        }
    }
}

You should create a folder called Helpers under the app folder, then create file called whatever.php inside and add the string whatever inside the $helpers array.

Done!

Edit

I'm no longer using this option, I'm currently using composer to load static files like helpers.

You can add the helpers directly at:

...
"autoload": {
    "files": [
        "app/helpers/my_helper.php",
        ...
    ]
},
...

Wep, another way to achieve the same result. We use it for its readability.

Instead of doing this hard-to-read sentence:

Type listType = new TypeToken<ArrayList<YourClass>>(){}.getType();
List<YourClass> list = new Gson().fromJson(jsonArray, listType);

Create a empty class that extends a List of your object:

public class YourClassList extends ArrayList<YourClass> {}

And use it when parsing the JSON:

List<YourClass> list = new Gson().fromJson(jsonArray, YourClassList.class);

Yes, by capturing the output of sp_who2 into a table and then selecting from the table, but that would be a bad way of doing it. First, because sp_who2, despite its popularity, its an undocumented procedure and you shouldn't rely on undocumented procedures. Second because all sp_who2 can do, and much more, can be obtained from sys.dm_exec_requests and other DMVs, and show can be filtered, ordered, joined and all the other goodies that come with queriable rowsets.

John O'Connor is right with the issue. The problem stays with installing ADT 17 and above. Found this link for fixing the error:

http://android.foxykeep.com/dev/how-to-fix-the-classdefnotfounderror-with-adt-17

Also be sure to check out \H, which toggles HTML output on/off. Not necessarily easy to read at the console, but interesting for dumping into a file (see \o) or pasting into an editor/browser window for viewing, especially with multiple rows of relatively complex data.

I had the same problem, tried all the solutions but nothing worked. The problem is with Windows 7 installed is 64 bit and all the software that you are installing should be 32 bit. Android SDK itself is 32 bit and it identifies only 32 bit JDK. So install following software.

1. JDK (32 bit)
2. Android SDK (while installing SDK, make sure install it in directory other than "C:\Program Files (x86)", more probably in other drive or in the directory where Eclipse is extracted)
3. Eclipse (32 bit) and finally ADT.

I tried it and all works fine.

Just adding to the solutions already suggested. Assumes same height, no resizing.

import sys
import glob
from PIL import Image
Image.MAX_IMAGE_PIXELS = 100000000  # For PIL Image error when handling very large images

imgs    = [ Image.open(i) for i in list_im ]

widths, heights = zip(*(i.size for i in imgs))
total_width = sum(widths)
max_height = max(heights)

new_im = Image.new('RGB', (total_width, max_height))

# Place first image
new_im.paste(imgs[0],(0,0))

# Iteratively append images in list horizontally
hoffset=0
for i in range(1,len(imgs),1):
    **hoffset=imgs[i-1].size[0]+hoffset  # update offset**
    new_im.paste(imgs[i],**(hoffset,0)**)

new_im.save('output_horizontal_montage.jpg')

Typically, Objective-C class are abstract by convention only—if the author documents a class as abstract, just don't use it without subclassing it. There is no compile-time enforcement that prevents instantiation of an abstract class, however. In fact, there is nothing to stop a user from providing implementations of abstract methods via a category (i.e. at runtime). You can force a user to at least override certain methods by raising an exception in those methods implementation in your abstract class:

[NSException raise:NSInternalInconsistencyException 
            format:@"You must override %@ in a subclass", NSStringFromSelector(_cmd)];

If your method returns a value, it's a bit easier to use

@throw [NSException exceptionWithName:NSInternalInconsistencyException
                               reason:[NSString stringWithFormat:@"You must override %@ in a subclass", NSStringFromSelector(_cmd)]
                             userInfo:nil];

as then you don't need to add a return statement from the method.

If the abstract class is really an interface (i.e. has no concrete method implementations), using an Objective-C protocol is the more appropriate option.

Self plug: I have just released a new Java HTML parser: jsoup. I mention it here because I think it will do what you are after.

Its party trick is a CSS selector syntax to find elements, e.g.:

String html = "<html><head><title>First parse</title></head>"
  + "<body><p>Parsed HTML into a doc.</p></body></html>";
Document doc = Jsoup.parse(html);
Elements links = doc.select("a");
Element head = doc.select("head").first();

See the Selector javadoc for more info.

This is a new project, so any ideas for improvement are very welcome!

So this is my final code after googling for 2 days on how to add a namespace and make soap request along with the SOAP envelope without adding proxy/Service Reference

class Request
{
    public static void Execute(string XML)
    {
        try
        {
            HttpWebRequest request = CreateWebRequest();
            XmlDocument soapEnvelopeXml = new XmlDocument();
            soapEnvelopeXml.LoadXml(AppendEnvelope(AddNamespace(XML)));

            using (Stream stream = request.GetRequestStream())
            {
                soapEnvelopeXml.Save(stream);
            }

            using (WebResponse response = request.GetResponse())
            {
                using (StreamReader rd = new StreamReader(response.GetResponseStream()))
                {
                    string soapResult = rd.ReadToEnd();
                    Console.WriteLine(soapResult);
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }
    }

    private static HttpWebRequest CreateWebRequest()
    {
        string ICMURL = System.Configuration.ConfigurationManager.AppSettings.Get("ICMUrl");
        HttpWebRequest webRequest = null;

        try
        {
            webRequest = (HttpWebRequest)WebRequest.Create(ICMURL);
            webRequest.Headers.Add(@"SOAP:Action");
            webRequest.ContentType = "text/xml;charset=\"utf-8\"";
            webRequest.Accept = "text/xml";
            webRequest.Method = "POST";
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }
        return webRequest;
    }

    private static string AddNamespace(string XML)
    {
        string result = string.Empty;
        try
        {

            XmlDocument xdoc = new XmlDocument();
            xdoc.LoadXml(XML);

            XmlElement temproot = xdoc.CreateElement("ws", "Request", "http://example.com/");
            temproot.InnerXml = xdoc.DocumentElement.InnerXml;
            result = temproot.OuterXml;

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }

        return result;
    }

    private static string AppendEnvelope(string data)
    {
        string head= @"<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" ><soapenv:Header/><soapenv:Body>";
        string end = @"</soapenv:Body></soapenv:Envelope>";
        return head + data + end;
    }
}

Currently working with Entity Framework Core 3.1.3. None of the above solutions fixed my issue.

However, installing the package Microsoft.EntityFrameworkCore.Proxies on my project fixed the issue. Now I can access the UseLazyLoadingProxies() method call when setting my DBContext options.

Hope this helps someone. See the following article:

Lazy Loading in EF Core

You will have to modify the below line:

<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>

modalRegister is the ID and hence requires a preceding # for ID reference in html.

So, the modified html code snippet would be as follows:

<li><a href="#" data-toggle="modal" data-target="#modalRegister">Register</a></li>

I tried all the above and it didn't work. This worked for me:

@Column(name="TestName")
public String getTestName(){//.........

Annotate the getter instead of the variable

this.Close();

Closes the form programmatically.

A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.

If you want to control the width of your data, then you could use the width sub-specifiers in the printf format string. Eg. :

printf("%5d", 2);

It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.

If you want complete control, you'll probably have to implement it yourself.

Make it simple-
At the end of the day when you are confused choosing containers in C++ use this flow chart image ( Say thanks to me ) :-

Vector-

1. vector is based on contagious memory
2. vector is way to go for small data-set
3. vector perform fastest while traversing on data-set
4. vector insertion deletion is slow on huge data-set but fast for very small

List-

1. list is based on heap memory
2. list is way to go for very huge data-set
3. list is comparatively slow on traversing small data-set but fast at huge data-set
4. list insertion deletion is fast on huge data-set but slow on smaller ones

By definition dictionaries are unordered, and therefore cannot be indexed. For that kind of functionality use an ordered dictionary. Python Ordered Dictionary

ValueErrors :In Python, a value is the information that is stored within a certain object. To encounter a ValueError in Python means that is a problem with the content of the object you tried to assign the value to.

in your case name,lastname and email 3 parameters are there but unpaidmembers only contain 2 of them.

name, lastname, email in unpaidMembers.items() so you should refer data or your code might be
lastname, email in unpaidMembers.items() or name, email in unpaidMembers.items()

If your OS is Windows, then it is very simple. When you install Android Studio, adb.exe is located in the following folder:

C:\Users\**your-user-name**\AppData\Local\Android\Sdk\platform-tools

Copy the path and paste in your environment variables.

Open your terminal and type: adb it's done!

I think You are using //--style="display:none"--// for hiding the div.

Use this code:

<script>
    function klikaj(i) {
        document.getElementById(i).style.display = 'block';
    }
</script>
<div id="thumb0" class="thumbs" onclick="klikaj('rad1')">Click Me..!</div>
<div id="rad1" class="thumbs" style="display:none">Helloooooo</div>

Square brackets:

jsObj['key' + i] = 'example' + 1;

In JavaScript, all arrays are objects, but not all objects are arrays. The primary difference (and one that's pretty hard to mimic with straight JavaScript and plain objects) is that array instances maintain the length property so that it reflects one plus the numeric value of the property whose name is numeric and whose value, when converted to a number, is the largest of all such properties. That sounds really weird, but it just means that given an array instance, the properties with names like "0", "5", "207", and so on, are all treated specially in that their existence determines the value of length. And, on top of that, the value of length can be set to remove such properties. Setting the length of an array to 0 effectively removes all properties whose names look like whole numbers.

OK, so that's what makes an array special. All of that, however, has nothing at all to do with how the JavaScript [ ] operator works. That operator is an object property access mechanism which works on any object. It's important to note in that regard that numeric array property names are not special as far as simple property access goes. They're just strings that happen to look like numbers, but JavaScript object property names can be any sort of string you like.

Thus, the way the [ ] operator works in a for loop iterating through an array:

for (var i = 0; i < myArray.length; ++i) {
  var value = myArray[i]; // property access
  // ...
}

is really no different from the way [ ] works when accessing a property whose name is some computed string:

var value = jsObj["key" + i];

The [ ] operator there is doing precisely the same thing in both instances. The fact that in one case the object involved happens to be an array is unimportant, in other words.

When setting property values using [ ], the story is the same except for the special behavior around maintaining the length property. If you set a property with a numeric key on an array instance:

myArray[200] = 5;

then (assuming that "200" is the biggest numeric property name) the length property will be updated to 201 as a side-effect of the property assignment. If the same thing is done to a plain object, however:

myObj[200] = 5;

there's no such side-effect. The property called "200" of both the array and the object will be set to the value 5 in otherwise the exact same way.

One might think that because that length behavior is kind-of handy, you might as well make all objects instances of the Array constructor instead of plain objects. There's nothing directly wrong about that (though it can be confusing, especially for people familiar with some other languages, for some properties to be included in the length but not others). However, if you're working with JSON serialization (a fairly common thing), understand that array instances are serialized to JSON in a way that only involves the numerically-named properties. Other properties added to the array will never appear in the serialized JSON form. So for example:

var obj = [];
obj[0] = "hello world";
obj["something"] = 5000;

var objJSON = JSON.stringify(obj);

the value of "objJSON" will be a string containing just ["hello world"]; the "something" property will be lost.

ES2015:

If you're able to use ES6 JavaScript features, you can use Computed Property Names to handle this very easily:

var key = 'DYNAMIC_KEY',
    obj = {
        [key]: 'ES6!'
    };

console.log(obj);
// > { 'DYNAMIC_KEY': 'ES6!' }

There are different approaches. If you want to do this from remote, issue flushall to that instance, through command line tool redis-cli or whatever tools i.e. telnet, a programming language SDK. Or just log in that server, kill the process, delete its dump.rdb file and appendonly.aof(backup them before deletion).

explode('.', 'a.b');

http://php.net/manual/ru/function.explode.php

Access 2007 can lose the CurrentDb: see http://support.microsoft.com/kb/167173, so in the event of getting "Object Invalid or no longer set" with the examples, use:

Dim db as Database
Dim rs As DAO.Recordset
Set db = CurrentDB
Set rs = db.OpenRecordset("SELECT * FROM myTable")

Check out the ideas at Mu Dynamics Research Labs - Blog Archive. I found this earlier this year - I forget the exact context where I came across it - and have adapted it into this code. We can debate the merits of adding an E at the front; it is applicable to the specific problem addressed, but not part of a general solution. I stashed this away in my 'vignettes' folder - where I keep interesting scraps of code in case I want them later. I'm embarrassed to say that I didn't keep a note of where this idea came from at the time.

Not necessarily the world's cleanest use of the C pre-processor - but it does prevent writing the material out multiple times.

Sounds like more work than its worth.

1) Why not just have a single JavaScript variable that stores a reference to the currently selected element\jQuery object.

2) Why not add a class to the currently selected element. Then you could query the DOM for the ".active" class or something.

We use @Temporal annotation to insert date, time or both in database table.Using TemporalType we can insert data, time or both int table.

@Temporal(TemporalType.DATE) // insert date
@Temporal(TemporalType.TIME) // insert time
@Temporal(TemporalType.TIMESTAMP) // insert  both time and date.

If you want to do it without any extra includes:

vector<IComponent*> myComponents; //assume it has items in it already.
void RemoveComponent(IComponent* componentToRemove)
{
    IComponent* juggler;

    if (componentToRemove != NULL)
    {
        for (int currComponentIndex = 0; currComponentIndex < myComponents.size(); currComponentIndex++)
        {
            if (componentToRemove == myComponents[currComponentIndex])
            {
                //Since we don't care about order, swap with the last element, then delete it.
                juggler = myComponents[currComponentIndex];
                myComponents[currComponentIndex] = myComponents[myComponents.size() - 1];
                myComponents[myComponents.size() - 1] = juggler;

                //Remove it from memory and let the vector know too.
                myComponents.pop_back();
                delete juggler;
            }
        }
    }
}

simple and best way to use date function

example

SELECT * FROM 
data 
WHERE date(datetime) = '2009-10-20' 

OR

SELECT * FROM 
data 
WHERE date(datetime ) >=   '2009-10-20'  && date(datetime )  <= '2009-10-20'

If you have a hard time remembering the default values (I know I have...) here's a short extract from BalusC's answer:

Component    | Submit          | Refresh
------------ | --------------- | --------------
f:ajax       | execute="@this" | render="@none"
p:ajax       | process="@this" | update="@none"
p:commandXXX | process="@form" | update="@none"

To remove the blue overlay on mobiles, you can use one of the following:

-webkit-tap-highlight-color: transparent; /* transparent with keyword */
-webkit-tap-highlight-color: rgba(0,0,0,0); /* transparent with rgba */
-webkit-tap-highlight-color: hsla(0,0,0,0); /* transparent with hsla */
-webkit-tap-highlight-color: #00000000; /* transparent with hex with alpha */
-webkit-tap-highlight-color: #0000; /* transparent with short hex with alpha */

However, unlike other properties, you can't use

-webkit-tap-highlight-color: none; /* none keyword */

In DevTools, this will show up as an 'invalid property value' or something.

To remove the blue/black/orange outline when focused, use this:

:focus {
    outline: none; /* no outline - for most browsers */
    box-shadow: none; /* no box shadow - for some browsers or if you are using Bootstrap */
}

The reason why I removed the box-shadow is because Bootsrap (and some browsers) sometimes add it to focused elements, so you can remove it using this.

But if anyone is navigating with a keyboard, they will get very confused indeed, because they rely on this outline to navigate. So you can replace it instead

:focus {
    outline: 100px dotted #f0f; /* 100px dotted pink outline */
}

You can target taps on mobile using :hover or :active, so you could use those to help, possibly. Or it could get confusing.

Full code:

element {
    -webkit-tap-highlight-color: transparent; /* remove tap highlight */
}
element:focus {
    outline: none; /* remove outline */
    box-shadow: none; /* remove box shadow */
}

Other information:

• If you would like to customise the -webkit-tap-highlight-color then you should set it to a semi-transparent color so the element underneath doesn't get hidden when tapped
• Please don't remove the outline from focused elements, or add some more styles for them.
• -webkit-tap-highlight-color has not got great browser support and is not standard. You can still use it, but watch out!

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

As A.B.Cada pointed out, you can query the database itself with sqlplus for the db version. That is the easiest way to findout what is the version of the db that is actively running. If there is more than one you will have to set the oracle_sid appropriately and run the query against each instance.

You can view /etc/oratab file to see what instance and what db home is used per instance. Its possible to have multiple version of oracle installed per server as well as multiple instances. The /etc/oratab file will list all instances and db home. From with the oracle db home you can run "opatch lsinventory" to find out what exaction version of the db is installed as well as any patches applied to that db installation.

You can use :

-XX:MaxPermSize=128m

to increase the space. But this usually only postpones the inevitable.

You can also enable the PermGen to be garbage collected

-XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

Usually this occurs when doing lots of redeploys. I am surprised you have it using something like indexing. Use virtualvm or jconsole to monitor the Perm gen space and check it levels off after warming up the indexing.

Maybe you should consider changing to another JVM like the IBM JVM. It does not have a Permanent Generation and is immune to this issue.

I have been awake for two days now trying to figure out how to download a file using jquery with ajax call. All the support i got could not help my situation until i try this.

Server Side

 [HttpPost]
    public string exportStaffAsCSV(IEnumerable<string> checkOne)
    {
        StringWriter sw = new StringWriter();
        try
        {
            var data = _db.staffInfoes.Where(t => checkOne.Contains(t.staffID)).ToList();

        }
        return sw.ToString();

    }

    //On ajax success request, it will be redirected to this method as a Get verb request with the returned date(string)
    public FileContentResult DownloadCSV(string data)
    {
        return File(new System.Text.UTF8Encoding().GetBytes(data), System.Net.Mime.MediaTypeNames.Application.Octet, filename);
        //this method will now return the file for download or open.
    }

Good luck.

Should also be able to do this:

total += eval(myInt1) + eval(myInt2) + eval(myInt3);

This helped me in a different, but similar, situation.

All the methods to tell if the variable is NaN or None:

None type

In [1]: from numpy import math

In [2]: a = None
In [3]: not a
Out[3]: True

In [4]: len(a or ()) == 0
Out[4]: True

In [5]: a == None
Out[5]: True

In [6]: a is None
Out[6]: True

In [7]: a != a
Out[7]: False

In [9]: math.isnan(a)
Traceback (most recent call last):
  File "<ipython-input-9-6d4d8c26d370>", line 1, in <module>
    math.isnan(a)
TypeError: a float is required

In [10]: len(a) == 0
Traceback (most recent call last):
  File "<ipython-input-10-65b72372873e>", line 1, in <module>
    len(a) == 0
TypeError: object of type 'NoneType' has no len()

NaN type

In [11]: b = float('nan')
In [12]: b
Out[12]: nan

In [13]: not b
Out[13]: False

In [14]: b != b
Out[14]: True

In [15]: math.isnan(b)
Out[15]: True

I think there are different ways to do this. Since im not familiar with asp i can only give you some hints to check for a specific filetype:

1) the safe way: get more informations about the header of the filetype you wish to pass. parse the uploaded file and compare the headers

2) the quick way: split the name of the file into two pieces -> name of the file and the ending of the file. check out the ending of the file and compare it to the filetype you want to allow to be uploaded

hope it helps :)

Type "set" and you will get a list of all the current variables. If you want something to persist put it in ~/.bashrc or ~/.bash_profile (if you're using bash)

DECLARE @id INT
DECLARE @filename NVARCHAR(100)
DECLARE @getid CURSOR

SET @getid = CURSOR FOR
SELECT top 3 id,
filename 
FROM  table

OPEN @getid
WHILE 1=1
BEGIN

    FETCH NEXT
    FROM @getid INTO @id, @filename
    IF @@FETCH_STATUS < 0 BREAK

    print @id

END


CLOSE @getid
DEALLOCATE @getid

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

I solved my problem with these two simple functions:

function imgExists(imgPath) {
    var http = jQuery.ajax({
                   type:"HEAD",
                   url: imgPath,
                   async: false
               });
    return http.status != 404;
}

function handleImageError() {
    var imgPath;

    $('img').each(function() {
        imgPath = $(this).attr('src');
        if (!imgExists(imgPath)) {
            $(this).attr('src', 'images/noimage.jpg');
        }
    });
}

There is no :unchecked pseudo class however if you use the :checked pseudo class and the sibling selector you can differentiate between both states. I believe all of the latest browsers support the :checked pseudo class, you can find more info from this resource: http://www.whatstyle.net/articles/18/pretty_form_controls_with_css

Your going to get better browser support with jquery... you can use a click function to detect when the click happens and if its checked or not, then you can add a class or remove a class as necessary...

From the Active Record docs:

$this->db->where_in();

Generates a WHERE field IN ('item', 'item') SQL query joined with AND if appropriate

$names = array('Frank', 'Todd', 'James');
$this->db->where_in('username', $names);
// Produces: WHERE username IN ('Frank', 'Todd', 'James')

If you use jQuery, you can do something like that :

$(document).ready(function(){$("input.autocompleteOff").attr("autocomplete","off");});

and use the autocompleteOff class where you want :

<input type="text" name="fieldName" id="fieldId" class="firstCSSClass otherCSSClass autocompleteOff" />

If you want ALL your input to be autocomplete=off, you can simply use that :

$(document).ready(function(){$("input").attr("autocomplete","off");});

I think I just ran into a similar issue where I was trying to center a login box (like the gmail login box). When resizing the window, the center box would overflow out of the browser window (top) as soon as the browser window became smaller than the box. Because of this, in a small window, even when scrolling up, the top content was lost.

I was able to fix this by replacing the centering method I used by the "margin: auto" way of centering the box in its container. This prevents the box from overflowing in my case, keeping all content available. (minimum margin seems to be 0).

Good Luck !

edit: margin: auto only works to vertically center something if the parent element has its display property set to "flex".

Hope this will help.

.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  display: flex;
  align-items: center;
  justify-content: center;
}
row {
  width: 100%;
}
.flex-item {
  background: tomato;
  padding: 5px;
  width: 200px;
  height: 150px;
  margin: 10px;
  line-height: 150px;
  color: white;
  font-weight: bold;
  font-size: 3em;
  text-align: center;
}

If you want that for display purposes, use java.text.DecimalFormat:

 new DecimalFormat("#.##").format(dblVar);

If you need it for calculations, use java.lang.Math:

 Math.floor(value * 100) / 100;

You're looking for the SyndicationFeed class, which does exactly that.

Someone might find this useful, I had a problem flattening array at some dimension, I would call it last dimension so for example, if I have array like:

array (
  'germany' => 
  array (
    'cars' => 
    array (
      'bmw' => 
      array (
        0 => 'm4',
        1 => 'x3',
        2 => 'x8',
      ),
    ),
  ),
  'france' => 
  array (
    'cars' => 
    array (
      'peugeot' => 
      array (
        0 => '206',
        1 => '3008',
        2 => '5008',
      ),
    ),
  ),
)

Or:

array (
  'earth' => 
  array (
    'germany' => 
    array (
      'cars' => 
      array (
        'bmw' => 
        array (
          0 => 'm4',
          1 => 'x3',
          2 => 'x8',
        ),
      ),
    ),
  ),
  'mars' => 
  array (
    'france' => 
    array (
      'cars' => 
      array (
        'peugeot' => 
        array (
          0 => '206',
          1 => '3008',
          2 => '5008',
        ),
      ),
    ),
  ),
)

For both of these arrays when I call method below I get result:

array (
  0 => 
  array (
    0 => 'm4',
    1 => 'x3',
    2 => 'x8',
  ),
  1 => 
  array (
    0 => '206',
    1 => '3008',
    2 => '5008',
  ),
)

So I am flattening to last array dimension which should stay the same, method below could be refactored to actually stop at any kind of level:

function flattenAggregatedArray($aggregatedArray) {
    $final = $lvls = [];
    $counter = 1;
    $lvls[$counter] = $aggregatedArray;


    $elem = current($aggregatedArray);

    while ($elem){
        while(is_array($elem)){
            $counter++;
            $lvls[$counter] = $elem;
            $elem =  current($elem);
        }

        $final[] = $lvls[$counter];
        $elem = next($lvls[--$counter]);
        while ( $elem  == null){
            if (isset($lvls[$counter-1])){
                $elem = next($lvls[--$counter]);
            }
            else{
                return $final;
            }
        }
    }
}

Not sure if this answers your question or not. Sorry if not

To get the error reported from the mysql database about your query you need to use your connection object as the focus.

so:

echo $mysqliDatabaseConnection->error

would echo the error being sent from mysql about your query.

Hope that helps

To remove you tube controls and title you can do something like this.

<iframe width="560" height="315" src="https://www.youtube.com/embed/zP0Wnb9RI9Q?autoplay=1&showinfo=0&controls=0" frameborder="0" allowfullscreen ></iframe>

check this example how it look

showinfo=0 is used to remove title and &controls=0 is used for remove controls like volume,play,pause,expend.

You may want to use a different structure altogether, but there are ways to do it in python 2.7.

d1 = OrderedDict([('a', '1'), ('b', '2')])
d2 = OrderedDict(c='3')
d2.update(d1)

d2 will then contain

>>> d2
OrderedDict([('c', '3'), ('a', '1'), ('b', '2')])

As mentioned by others, in python 3.2 you can use OrderedDict.move_to_end('c', last=False) to move a given key after insertion.

Note: Take into consideration that the first option is slower for large datasets due to creation of a new OrderedDict and copying of old values.

In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$"); for further information see the javadoc

Extremely simple method jsfiddle

HTML

<div id="container">
    <div id="element">
        some text
    </div>

#container {
    width: 50%; /* desired width */
}

#element {
    height: 0;
    padding-bottom: 100%;
}

You can use Convert.ChangeType() - It allows you to use runtime information on any IConvertible type to change representation formats. Not all conversions are possible, though, and you may need to write special case logic if you want to support conversions from types that are not IConvertible.

The corresponding code (without exception handling or special case logic) would be:

Ship ship = new Ship();
string value = "5.5";
PropertyInfo propertyInfo = ship.GetType().GetProperty("Latitude");
propertyInfo.SetValue(ship, Convert.ChangeType(value, propertyInfo.PropertyType), null);

Option 1 - Android PCAP

Limitation

Android PCAP should work so long as:

Your device runs Android 4.0 or higher (or, in theory, the few devices which run Android 3.2). Earlier versions of Android do not have a USB Host API

Option 2 - TcpDump

Limitation

Phone should be rooted

Option 3 - bitshark (I would prefer this)

Limitation

Phone should be rooted

Reason - the generated PCAP files can be analyzed in WireShark which helps us in doing the analysis.

Other Options without rooting your phone

1. tPacketCapture

https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en

Advantages

Using tPacketCapture is very easy, captured packet save into a PCAP file that can be easily analyzed by using a network protocol analyzer application such as Wireshark.

2. You can route your android mobile traffic to PC and capture the traffic in the desktop using any network sniffing tool.

Let me post a solution here for C++03 that I consider the cleanest possible.*

#define DECLARE_LAMBDA(NAME, RETURN_TYPE, FUNCTION) \
    struct { RETURN_TYPE operator () FUNCTION } NAME;

...

int main(){
  DECLARE_LAMBDA(demoLambda, void, (){ cout<<"I'm a lambda!"<<endl; });
  demoLambda();

  DECLARE_LAMBDA(plus, int, (int i, int j){
    return i+j;
  });
  cout << "plus(1,2)=" << plus(1,2) << endl;
  return 0;
}

(*) in the C++ world using macros is never considered clean.

If you add IntentFilters for your service, you are saying you want to expose your service to other applications, then it may be stopped unexpectedly by other applications.

Couldn't you just make the numbers strings, concatenate them, and convert the strings to an integer value?

If you are working on a Unix system, the fastest method is the following shell command

cat FILE_NAME.CSV | wc -l

From Jupyter Notebook or iPython, you can use it with a !:

! cat FILE_NAME.CSV | wc -l

None of the solutions provided seemed at all easiest to me, so I'd like to add my own way.

Basically, you get the list of the elements instead of just the element and then count the results; if it's zero, then it doesn't exist. Example:

if driver.find_elements_by_css_selector('#element'):
    print "Element exists"

Notice the "s" in find_elements_by_css_selector to make sure it can be countable.

EDIT: I was checking the len( of the list, but I recently learned that an empty list is falsey, so you don't need to get the length of the list at all, leaving for even simpler code.

Also, another answer says that using xpath is more reliable, which is just not true. See What is the difference between css-selector & Xpath? which is better(according to performance & for cross browser testing)?

Running Eclipse v4.3 (Kepler), the steps outlined by AlvaroCachoperro do the trick for the Java text editor and console window text.

Many of the text font options, including the Java Editor Text Font note, are "set to default: Text Font". The 'default' can be found and configured as follows:

On the Eclipse toolbar, select Window ? Preferences. Drill down to: (General ? Appearance ? Colors and Fonts ? Basic ? Text Font) (at the bottom)

• Click Edit and select the font, style and size
• Click OK in the Font dialog
• Click Apply in the Preferences dialog to check it
• Click OK in the Preferences dialog to save it

Eclipse will remember your settings for your current workspace.

I teach programming and use the larger font for the students in the back.

use sep='\s*,\s*' so that you will take care of spaces in column-names:

transactions = pd.read_csv('transactions.csv', sep=r'\s*,\s*',
                           header=0, encoding='ascii', engine='python')

alternatively you can make sure that you don't have unquoted spaces in your CSV file and use your command (unchanged)

prove:

print(transactions.columns.tolist())

Output:

['product_id', 'customer_id', 'store_id', 'promotion_id', 'month_of_year', 'quarter', 'the_year', 'store_sales', 'store_cost', 'unit_sales', 'fact_count']

Can you clarify your question? What is "ohHover" in this case and how does it correspond to a delay in hover time?

That said, I think what you probably want is...

var timeout;
element.onmouseover = function(e) {
    timeout = setTimeout(function() {
        // ...
    }, delayTimeMs)
};
element.onmouseout = function(e) {
    if(timeout) {
        clearTimeout(timeout);
    }
};

Or addEventListener/attachEvent or your favorite library's event abstraction method.

Here is my version based on the @peterincumbria answer:

using var scope = _serviceProvider.CreateScope();
var dbContext = scope.ServiceProvider.GetRequiredService<AppDbContext>();
return await dbContext.Database.CanConnectAsync(cToken);

I'm using Observable for polling health checking by interval and handling return value of the function. try-catch is not needed here because:

Yep _MSC_VER is the macro that'll get you the compiler version. The last number of releases of Visual C++ have been of the form <compiler-major-version>.00.<build-number>, where 00 is the minor number. So _MSC_VER will evaluate to <major-version><minor-version>.

You can use code like this:

#if (_MSC_VER == 1500)
   // ... Do VC9/Visual Studio 2008 specific stuff
#elif (_MSC_VER == 1600)
   // ... Do VC10/Visual Studio 2010 specific stuff
#elif (_MSC_VER == 1700)
   // ... Do VC11/Visual Studio 2012 specific stuff
#endif

It appears updates between successive releases of the compiler, have not modified the compiler-minor-version, so the following code is not required:

#if (_MSC_VER >= 1500 && _MSC_VER <= 1600)
   // ... Do VC9/Visual Studio 2008 specific stuff
#endif

Access to more detailed versioning information (such as compiler build number) can be found using other builtin pre-processor variables here.

Regex.Split("abc][rfd][5][,][.", @"\]\]");

In iReport 5.5.0, just right click the report base hierarchy in Report Inspector Bloc Window viewer, then click Compile Report

You can now see the result in the console down. If no Errors, you may see something like this.

Just listen to what the warning is telling you:

Reshape your data either X.reshape(-1, 1) if your data has a single feature/column and X.reshape(1, -1) if it contains a single sample.

For your example type(if you have more than one feature/column):

temp = temp.reshape(1,-1) 

For one feature/column:

temp = temp.reshape(-1,1)

Here's a snippet of hql that we use. (Names have been changed to protect identities)

String queryString = "select distinct f from Foo f inner join foo.bars as b" +
                " where f.creationDate >= ? and f.creationDate < ? and b.bar = ?";
        return getHibernateTemplate().find(queryString, new Object[] {startDate, endDate, bar});

Javascript is single-threaded, so by nature there should not be a sleep function because sleeping will block the thread. setTimeout is a way to get around this by posting an event to the queue to be executed later without blocking the thread. But if you want a true sleep function, you can write something like this:

function sleep(miliseconds) {
   var currentTime = new Date().getTime();

   while (currentTime + miliseconds >= new Date().getTime()) {
   }
}

Note: The above code is NOT recommended.

For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.

Try something like

convert -density 300 image.eps -resize 1024x1024 image.jpg

Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.

The order of the arguments matters! The -density X argument needs to go before image.eps because you want to affect the resolution that the input file is rendered at.

This is not super obvious in the manpage for convert, but is hinted at:

SYNOPSIS

convert [input-option] input-file [output-option] output-file

Using your example, you could do:

public void doit(A a) {
    if(a instanceof B) {
        // needs to cast to B to access draw2 which isn't present in A
        // note that this is probably not a good OO-design, but that would
        // be out-of-scope for this discussion :)
        ((B)a).draw2();
    }
    a.draw();
}

I think you might be able to hack out a solution that involves setting your shell to a script containing:

#!/bin/sh
bash | tee /var/log/bash.out.log

Then if you set $PROMPT_COMMAND to output a delimiter, you can write a helper function (maybe called _) that gets you the last chunk of that log, so you can use it like:

% find lots*of*files
...
% echo "$(_)"
... # same output, but doesn't run the command again

//Class Name
public class ClassName {
//Make it runnable
public static void main(String args[]) throws MalformedURLException{
//Get the URL
URL img = this.getClass().getResource("src/Name.gif");
//Make it to a Icon
Icon icon = new ImageIcon(img);
//Make a new JLabel that shows "icon"
JLabel Gif = new JLabel(icon);

//Make a new Window
JFrame main = new JFrame("gif");
//adds the JLabel to the Window
main.getContentPane().add(Gif);
//Shows where and how big the Window is
main.setBounds(x, y, H, W);
//set the Default Close Operation to Exit everything on Close
main.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Open the Window
main.setVisible(true);
   }
}

If you want to just "set" the actual filename, without incurring the overhead of loading and re-saving the file (!!), or resorting to using a charfield (!!!), you might want to try something like this --

model_instance.myfile = model_instance.myfile.field.attr_class(model_instance, model_instance.myfile.field, 'my-filename.jpg')

This will light up your model_instance.myfile.url and all the rest of them just as if you'd actually uploaded the file.

Like @t-stone says, what we really want, is to be able to set instance.myfile.path = 'my-filename.jpg', but Django doesn't currently support that.

As said before, VBA does not support Multithreading.

But you don't need to use C# or vbScript to start other VBA worker threads.

I use VBA to create VBA worker threads.

First copy the makro workbook for every thread you want to start.

Then you can start new Excel Instances (running in another Thread) simply by creating an instance of Excel.Application (to avoid errors i have to set the new application to visible).

To actually run some task in another thread i can then start a makro in the other application with parameters form the master workbook.

To return to the master workbook thread without waiting i simply use Application.OnTime in the worker thread (where i need it).

As semaphore i simply use a collection that is shared with all threads. For callbacks pass the master workbook to the worker thread. There the runMakroInOtherInstance Function can be reused to start a callback.

'Create new thread and return reference to workbook of worker thread
Public Function openNewInstance(ByVal fileName As String, Optional ByVal openVisible As Boolean = True) As Workbook
    Dim newApp As New Excel.Application
    ThisWorkbook.SaveCopyAs ThisWorkbook.Path & "\" & fileName
    If openVisible Then newApp.Visible = True
    Set openNewInstance = newApp.Workbooks.Open(ThisWorkbook.Path & "\" & fileName, False, False) 
End Function

'Start macro in other instance and wait for return (OnTime used in target macro)
Public Sub runMakroInOtherInstance(ByRef otherWkb As Workbook, ByVal strMakro As String, ParamArray var() As Variant)
    Dim makroName As String
    makroName = "'" & otherWkb.Name & "'!" & strMakro
    Select Case UBound(var)
        Case -1:
            otherWkb.Application.Run makroName
        Case 0:
            otherWkb.Application.Run makroName, var(0)
        Case 1:
            otherWkb.Application.Run makroName, var(0), var(1)
        Case 2:
            otherWkb.Application.Run makroName, var(0), var(1), var(2)
        Case 3:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3)
        Case 4:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3), var(4)
        Case 5:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3), var(4), var(5)
    End Select

I followed the suggested dependencies and installed them as the above link suggests:

sudo apt-get install nodejs-dev node-gyp libssl1.0-dev

and then

sudo apt-get install npm

If your Web Host is through C Panel Enable G ZIP Compression on Apache C Panel

Go to CPanel and check for software tab.

Previously Optimize website used to work but now a new option is available i.e "MultiPHP INI Editor".

Select the domain name you want to compress.

Scroll down to bottom until you find zip output compression and enable it.

Now check again for the G ZIP Compression.

In stored procedure, you just need to write the select query like the below:

CREATE PROCEDURE TestProcedure
AS
BEGIN
    SELECT ID, Name 
    FROM Test
END

On C# side, you can access using Reader, datatable, adapter.

Using adapter has just explained by Susanna Floora.

Using Reader:

SqlConnection connection = new SqlConnection(ConnectionString);

command = new SqlCommand("TestProcedure", connection);
command.CommandType = System.Data.CommandType.StoredProcedure;
connection.Open();
SqlDataReader reader = command.ExecuteReader();

List<Test> TestList = new List<Test>();
Test test = null;

while (reader.Read())
{
    test = new Test();
    test.ID = int.Parse(reader["ID"].ToString());
    test.Name = reader["Name"].ToString();
    TestList.Add(test);
}

gvGrid.DataSource = TestList;
gvGrid.DataBind();

Using dataTable:

SqlConnection connection = new SqlConnection(ConnectionString);

command = new SqlCommand("TestProcedure", connection);
command.CommandType = System.Data.CommandType.StoredProcedure;
connection.Open();

DataTable dt = new DataTable();

dt.Load(command.ExecuteReader());
gvGrid.DataSource = dt;
gvGrid.DataBind();

I hope it will help you. :)

The keyword "Selection" is already a vba Range object so you can use it directly, and you don't have to select cells to copy, for example you can be on Sheet1 and issue these commands:

ThisWorkbook.worksheets("sheet2").Range("namedRange_or_address").Copy
ThisWorkbook.worksheets("sheet1").Range("namedRange_or_address").Paste

If it is a multiple selection you should use the Area object in a for loop:

Dim a as Range
For Each a in ActiveSheet.Selection.Areas
    a.Copy
    ThisWorkbook.worksheets("sheet2").Range("A1").Paste
Next

You need to set the default timezone smth like this :

date_default_timezone_set('Europe/Bucharest');

More info about this in http://php.net/manual/en/function.date-default-timezone-set.php

Or you could use @ in front of date to suppress the warning however as the warning states it's not safe to rely on the servers default timezone

A modern native solution if anyone is interested:

const arr = Object.keys(obj).map(key => ({ key, value: obj[key] }));

or (not IE):

const arr = Object.entries(obj).map(([key, value]) => ({ key, value }));

You could possibly create a cookie if thats allowed in your requirment. If you choose to take the cookie route then the solution could be as follows. Also the benefit with cookie is after the user closes the Browser and Re-opens, if the cookie has not been deleted the value will be persisted.

Cookie *Create and Store a Cookie:*

function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}

The function which will return the specified cookie:

function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x==c_name)
    {
    return unescape(y);
    }
  }
}

Display a welcome message if the cookie is set

function checkCookie()
{
var username=getCookie("username");
  if (username!=null && username!="")
  {
  alert("Welcome again " + username);
  }
else 
  {
  username=prompt("Please enter your name:","");
  if (username!=null && username!="")
    {
    setCookie("username",username,365);
    }
  }
}

The above solution is saving the value through cookies. Its a pretty standard way without storing the value on the server side.

Jquery

Set a value to the session storage.

Javascript:

$.sessionStorage( 'foo', {data:'bar'} );

Retrieve the value:

$.sessionStorage( 'foo', {data:'bar'} );

$.sessionStorage( 'foo' );Results:
{data:'bar'}

Local Storage Now lets take a look at Local storage. Lets say for example you have an array of variables that you are wanting to persist. You could do as follows:

var names=[];
names[0]=prompt("New name?");
localStorage['names']=JSON.stringify(names);

//...
var storedNames=JSON.parse(localStorage['names']);

Server Side Example using ASP.NET

Adding to Sesion

Session["FirstName"] = FirstNameTextBox.Text;
Session["LastName"] = LastNameTextBox.Text;

// When retrieving an object from session state, cast it to // the appropriate type.

ArrayList stockPicks = (ArrayList)Session["StockPicks"];

// Write the modified stock picks list back to session state.
Session["StockPicks"] = stockPicks;

I hope that answered your question.

As it has been pointed out, it depends on the type. For built-in data types, it is best to pass by value. Even some very small structures, such as a pair of ints can perform better by passing by value.

Here is an example, assume you have an integer value and you want pass it to another routine. If that value has been optimized to be stored in a register, then if you want to pass it be reference, it first must be stored in memory and then a pointer to that memory placed on the stack to perform the call. If it was being passed by value, all that is required is the register pushed onto the stack. (The details are a bit more complicated than that given different calling systems and CPUs).

If you are doing template programming, you are usually forced to always pass by const ref since you don't know the types being passed in. Passing penalties for passing something bad by value are much worse than the penalties of passing a built-in type by const ref.

Similar to accepted answer but allows use of ColumnNames and binds to RowDataBound().

Dictionary<string, int> _headerIndiciesForAbcGridView = null;

protected void abcGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (_headerIndiciesForAbcGridView == null) // builds once per http request
    {
        int index = 0;
        _headerIndiciesForAbcGridView = ((Table)((GridView)sender).Controls[0]).Rows[0].Cells
            .Cast<TableCell>()
            .ToDictionary(c => c.Text, c => index++);
    }

    e.Row.Cells[_headerIndiciesForAbcGridView["theColumnName"]].Visible = false;
}

Not sure if it works with RowCreated().

You can also change the date format for the session. This is useful, for example, in Perl DBI, where the to_date() function is not available:

ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD'

You can permanently set the default nls_date_format as well:

ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY-MM-DD'

In Perl DBI you can run these commands with the do() method:

$db->do("ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD');

http://www.dba-oracle.com/t_dbi_interface1.htm https://community.oracle.com/thread/682596?start=15&tstart=0

None of the above mentioned solution worked for me due to some reason. Here is my solution. It's pretty basic.

curl -X GET API_ENDPOINT -H 'Content-Type: application/json' -d 'JSON_DATA'

API_ENDPOINT is your api endpoint e.g: http://127.0.0.1:80/api

-H has been used to added header content.

JSON_DATA is your request body it can be something like :: {"data_key": "value"} . ' ' surrounding JSON_DATA are important.

Anything after -d is the data which you need to send in the GET request

Have you tried to add a schema to xml catalog?

in eclipse to avoid the "no grammar constraints (dtd or xml schema) detected for the document." i use to add an xsd schema file to the xml catalog under

"Window \ preferences \ xml \ xml catalog \ User specified entries".

Click "Add" button on the right.

Example:

<?xml version="1.0" encoding="UTF-8"?>
<HolidayRequest xmlns="http://mycompany.com/hr/schemas">
    <Holiday>
        <StartDate>2006-07-03</StartDate>
        <EndDate>2006-07-07</EndDate>
    </Holiday>
    <Employee>
        <Number>42</Number>
        <FirstName>Arjen</FirstName>
        <LastName>Poutsma</LastName>
    </Employee>
</HolidayRequest>

From this xml i have generated and saved an xsd under: /home/my_user/xsd/my_xsd.xsd

As Location: /home/my_user/xsd/my_xsd.xsd

As key type: Namespace name

As key: http://mycompany.com/hr/schemas

Close and reopen the xml file and do some changes to violate the schema, you should be notified

Pscp.exe is painfully slow.

Uploading files using WinSCP is like 10 times faster.

So, to do that from command line, first you got to add the winscp.com file to your %PATH%. It's not a top-level domain, but an executable .com file, which is located in your WinSCP installation directory.

Then just issue a simple command and your file will be uploaded much faster putty ever could:

WinSCP.com /command "open sftp://username:[email protected]:22" "put your_large_file.zip /var/www/somedirectory/" "exit"

And make sure your check the synchronize folders feature, which is basically what rsync does, so you won't ever want to use pscp.exe again.

WinSCP.com /command "help synchronize"

if some directory/folder does not exist but somehow you navigated to that directory in that case you can see this Error,

for example:

• currently, you are in "mno" directory (path = abc/def/ghi/jkl/mno
• run "sudo su" and delete mno
• goto the "ghi" directory and delete "jkl" directory
• now you are in "ghi" directory (path abc/def/ghi)
• run "exit"
• after running the "exit", you will get that Error
• now you will be in "mno"(path = abc/def/ghi/jkl/mno) folder. that does not exist.

so, Generally this Error will show when Directory doesn't exist.

to fix this, simply run "cd;" or you can move to any other directory which exists.

PURE JAVASCRIPT SCROLLER CLASS

This is an old question but I thought I could answer with some fancy stuff and some more options to play with if you want to have a bit more control over the animation.

Here it is a pure JS Class to take care of the scrolling for you:

SEE DEMO AT CODEPEN OR GO TO THE BOTTOM AND RUN THE SINPET

// ------------------- USE EXAMPLE ---------------------
// *Set options
var options = {
  'showButtonAfter': 200, // show button after scroling down this amount of px
  'animate': "linear", // [false|normal|linear] - for false no aditional settings are needed

  'normal': { // applys only if [animate: normal] - set scroll loop distanceLeft/steps|ms
    'steps': 20, // the more steps per loop the slower animation gets
    'ms': 10 // the less ms the quicker your animation gets
  }, 
  'linear': { // applys only if [animate: linear] - set scroll px|ms
    'px': 30, // the more px the quicker your animation gets
    'ms': 10 // the less ms the quicker your animation gets
  }, 
};


// *Create new Scroller and run it.
var scroll = new Scroller(options);
scroll.init();

I no longer work on Android project for a while. Although the below provides some clue to how an android studio project can be configured, but I can't guarantee it works flawlessly.

In principle, IntelliJ respects the build file and will try to use it to configure the IDE project. It's not true in the other way round, IDE changes normally will not affect the build file.

Since most Android projects are built by Gradle, it's always a good idea to understand this tool.

I'd suggest referring to @skyfishjy's answer, as it seems to be more updated than this one.

The below is not updated

Although android studio is based on IntelliJ IDEA, at the same time it relies on gradle to build your apk. As of 0.2.3, these two doesn't play nicely in term of configuring from GUI. As a result, in addition to use the GUI to setup dependencies, it will also require you to edit the build.gradle file manually.

Assuming you have a Test Project > Test structure. The build.gradle file you're looking for is located at TestProject/Test/build.gradle

Look for the dependencies section, and make sure you have

compile 'com.android.support:support-v4:13.0.+'

Below is an example.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

You can also add 3rd party libraries from the maven repository

compile group: 'com.google.code.gson', name: 'gson', version: '2.2.4'

The above snippet will add gson 2.2.4 for you.

In my experiment, it seems that adding the gradle will also setup correct IntelliJ dependencies for you.

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

The important thing of table-layout: fixed is that the column widths are determined by the first row of the table.

So

if your table structure is as follow (standard table structure)

<table>
  <thead>
      <tr>
          <th> First column </th>
          <th> Second column </th>
          <th> Third column </th>        
      </tr>
  </thead>

   <tbody>
      <tr>
          <td> First column </td>
          <td> Second column </td>
          <td> Third column </td>        
      </tr>
  </tbody>

if you would like to give a width to second column then

<style> 
    table{
        table-layout:fixed;
        width: 100%;
    }

    table tr th:nth-child(2){
       width: 60%;
     }

</style>

Please look that we style the th not the td.

If you want to use SelectedValue then your combobox must be databound.

To set up the combobox:

ComboBox1.DataSource = GetMailItems()
ComboBox1.DisplayMember = "Name"
ComboBox1.ValueMember = "ID"

To get the data:

Function GetMailItems() As List(Of MailItem)

    Dim mailItems = New List(Of MailItem)

    Command = New MySqlCommand("SELECT * FROM `maillist` WHERE l_id = '" & id & "'", connection)
    Command.CommandTimeout = 30
    Reader = Command.ExecuteReader()

    If Reader.HasRows = True Then
        While Reader.Read()
            mailItems.Add(New MailItem(Reader("ID"), Reader("name")))
        End While
    End If

    Return mailItems

End Function

Public Class MailItem

    Public Sub New(ByVal id As Integer, ByVal name As String)
        mID = id
        mName = name
    End Sub

    Private mID As Integer
    Public Property ID() As Integer
        Get
            Return mID
        End Get
        Set(ByVal value As Integer)
            mID = value
        End Set
    End Property

    Private mName As String
    Public Property Name() As String
        Get
            Return mName
        End Get
        Set(ByVal value As String)
            mName = value
        End Set
    End Property

End Class

The basic problem here is that building and linking a C++ program depends heavily on the build system in use. You will need to support the following distinct tasks, using some combination of plugins and custom code:

1. General C++ language support for the editor. This is usually done using ms-vscode.cpptools, which most people expect to also handle a lot of other stuff, like build support. Let me save you some time: it doesn't. However, you will probably want it anyway.

2. Build, clean, and rebuild tasks. This is where your choice of build system becomes a huge deal. You will find plugins for things like CMake and Autoconf (god help you), but if you're using something like Meson and Ninja, you are going to have to write some helper scripts, and configure a custom "tasks.json" file to handle these. Microsoft has totally changed everything about that file over the last few versions, right down to what it is supposed to be called and the places (yes, placeS) it can go, to say nothing of completely changing the format. Worse, they've SORT OF kept backward compatibility, to be sure to use the "version" key to specify which variant you want. See details here:

WARNING: IN ALL OF THE ANSWERS BELOW, ANYTHING THAT BEGINS WITH A "VERSION" TAG BELOW 2.0.0 IS OBSOLETE.

Here's the closest thing I've got at the moment. Note that I kick most of the heavy lifting off to scripts, this doesn't really give me any menu entries I can live with, and there isn't any good way to select between debug and release without just making another three explicit entries in here.

Note that, in theory, this file is supposed to work if you put it in the workspace root, so that you aren't stuck checking files in hidden directories (.vscode) into your revision control system. I have yet to see that actually work; test it, but if it fails, put it in .vscode. Either way, the IDE will bitch if it isn't there anyway. (Yes, at the moment, this means I have been forced to check .vscode into subversion, which I'm not happy about.) Note that my build scripts (not shown) simply create (or recreate) a DEBUG directory using, in my case, meson, and build inside it (using, in my case, ninja).

3. Run, debug, attach, halt. These are another set of tasks, defined in "launch.json". Or at least they used to be. Microsoft has made such a hash of the documentation, I'm not even sure anymore.

Others explained very well and just want to give with simple examples.

Single quotes can be used around text to prevent the shell from interpreting any special characters. Dollar signs, spaces, ampersands, asterisks and other special characters are all ignored when enclosed within single quotes.

$ echo 'All sorts of things are ignored in single quotes, like $ & * ; |.' 

It will give this:

All sorts of things are ignored in single quotes, like $ & * ; |.

The only thing that cannot be put within single quotes is a single quote.

Double quotes act similarly to single quotes, except double quotes still allow the shell to interpret dollar signs, back quotes and backslashes. It is already known that backslashes prevent a single special character from being interpreted. This can be useful within double quotes if a dollar sign needs to be used as text instead of for a variable. It also allows double quotes to be escaped so they are not interpreted as the end of a quoted string.

$ echo "Here's how we can use single ' and double \" quotes within double quotes"

It will give this:

Here's how we can use single ' and double " quotes within double quotes

It may also be noticed that the apostrophe, which would otherwise be interpreted as the beginning of a quoted string, is ignored within double quotes. Variables, however, are interpreted and substituted with their values within double quotes.

$ echo "The current Oracle SID is $ORACLE_SID"

It will give this:

The current Oracle SID is test

Back quotes are wholly unlike single or double quotes. Instead of being used to prevent the interpretation of special characters, back quotes actually force the execution of the commands they enclose. After the enclosed commands are executed, their output is substituted in place of the back quotes in the original line. This will be clearer with an example.

$ today=`date '+%A, %B %d, %Y'`
$ echo $today 

It will give this:

Monday, September 28, 2015 

Much more expressive way,

jQuery('<div/>', {
    "id": 'foo',
    "name": 'mainDiv',
    "class": 'wrapper',
    "click": function() {
      jQuery(this).toggleClass("test");
    }}).appendTo('selector');

It's a great question, but be warned that you're treading in dangerous waters here. When you're deleting code you will have to make sure you're compiling and testing often.

One great tool come to mind:

NDepend - this tool is just amazing. It takes a little while to grok, and after the first 10 minutes I think most developers just say "Screw it!" and delete the app. Once you get a good feel for NDepend, it gives you amazing insight to how your apps are coupled. Check it out: http://www.ndepend.com/. Most importantly, this tool will allow you to view methods which do not have any direct callers. It will also show you the inverse, a complete call tree for any method in the assembly (or even between assemblies).

Whatever tool you choose, it's not a task to take lightly. Especially if you're dealing with public methods on library type assemblies, as you may never know when an app is referencing them.

You can add a watchpoint for each variable you're interested in.

A watchpoint is a special breakpoint that stops the execution of an application whenever the value of a given expression changes, without specifying where it might occur. Unlike breakpoints (which are line-specific), watchpoints are associated with files. They take effect whenever a specified condition is true, regardless of when or where it occurred. You can set a watchpoint on a global variable by highlighting the variable in the editor, or by selecting it in the Outline view.

A single listening port can accept more than one connection simultaneously.

There is a '64K' limit that is often cited, but that is per client per server port, and needs clarifying.

Each TCP/IP packet has basically four fields for addressing. These are:

source_ip source_port destination_ip destination_port
<----- client ------> <--------- server ------------>

Inside the TCP stack, these four fields are used as a compound key to match up packets to connections (e.g. file descriptors).

If a client has many connections to the same port on the same destination, then three of those fields will be the same - only source_port varies to differentiate the different connections. Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K.

However, multiple clients can each have up to 64K connections to some server's port, and if the server has multiple ports or either is multi-homed then you can multiply that further.

So the real limit is file descriptors. Each individual socket connection is given a file descriptor, so the limit is really the number of file descriptors that the system has been configured to allow and resources to handle. The maximum limit is typically up over 300K, but is configurable e.g. with sysctl.

The realistic limits being boasted about for normal boxes are around 80K for example single threaded Jabber messaging servers.

Working plunk here.

To add the new input just once, use the following code:

$(document).ready(function()
{
  $("#insertAfterBtn").one("click", function(e)
  {
    var r = $('<input/>', { type: "button", id: "field", value: "I'm a button" });

    $("body").append(r);
  });
});

[... source stripped here ...]

<body>
    <button id="insertAfterBtn">Insert after</button>
</body>

[... source stripped here ...]

To make it work in w3 editor, copy/paste the code below into 'source code' section inside w3 editor and then hit 'Submit Code':

<script type="text/javascript">
$(document).ready(function()
{
  // when dom is ready, call this method to add an input to 'body' tag.
  addInputTo($("body"));

  // when dom is ready, call this method to add an input to a div with class=myClass
  addInputTo($(".myClass"));

  // when dom is ready, call this method to add an input to a div with id=myId
  addInputTo($("#myId"));

  $("#insertAfterBtn").one("click", function(e)
  {
    var r = $('<input/>', { type: "button", id: "field", value: "I'm a button" });

    $("body").append(r);

For even more robustness:

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

and

...
var frame_win = getIframeWindow( frames['nameOfMyIframe'] );

if (frame_win) {
  $(frame_win.contentDocument || frame_win.document).find('some selector').doStuff();
  ...
}
...

You can do that using Requestify, a very simple and cool HTTP client I wrote for nodeJS, it support easy use of cookies and it also supports caching.

To perform a request with a cookie attached just do the following:

var requestify = require('requestify');
requestify.post('http://google.com', {}, {
    cookies: {
        sessionCookie: 'session-cookie-data'   
    }
});

You should use the Service , because $rootscope is access from whole Application , and it increases the load, or youc use the rootparams if your data is not more.

I'm using Visual Studio 2019. I used the shortcut below:

I have found Transform Feedback to be a useful tool for debugging vertex shaders. You can use this to capture the values of VS outputs, and read them back on the CPU side, without having to go through the rasterizer.

Here is another link to a tutorial on Transform Feedback.

var $list = $('#divname input[id^="q17_"]');   // get all input controls with id q17_

// once you have $list you can do whatever you want

var ControlCnt = $list.length;
// Now loop through list of controls
$list.each( function() {

    var id = $(this).prop("id");      // get id
    var cbx = '';
    if ($(this).is(':checkbox') || $(this).is(':radio')) {
        // Need to see if this control is checked
    }
    else { 
        // Nope, not a checked control - so do something else
    }

});

well, you can do it a lot of ways... one of them is to create a HttpRequest. I would advise you against calling your own webapi from your own MVC (the idea is redundant...) but, here's a end to end tutorial.

What is wrong with this approach? Why would I want to use Redux Thunk or Redux Promise, as the documentation suggests?

There is nothing wrong with this approach. It’s just inconvenient in a large application because you’ll have different components performing the same actions, you might want to debounce some actions, or keep some local state like auto-incrementing IDs close to action creators, etc. So it is just easier from the maintenance point of view to extract action creators into separate functions.

You can read my answer to “How to dispatch a Redux action with a timeout” for a more detailed walkthrough.

Middleware like Redux Thunk or Redux Promise just gives you “syntax sugar” for dispatching thunks or promises, but you don’t have to use it.

So, without any middleware, your action creator might look like

// action creator
function loadData(dispatch, userId) { // needs to dispatch, so it is first argument
  return fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_DATA_FAILURE', err })
    );
}

// component
componentWillMount() {
  loadData(this.props.dispatch, this.props.userId); // don't forget to pass dispatch
}

But with Thunk Middleware you can write it like this:

// action creator
function loadData(userId) {
  return dispatch => fetch(`http://data.com/${userId}`) // Redux Thunk handles these
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_DATA_FAILURE', err })
    );
}

// component
componentWillMount() {
  this.props.dispatch(loadData(this.props.userId)); // dispatch like you usually do
}

So there is no huge difference. One thing I like about the latter approach is that the component doesn’t care that the action creator is async. It just calls dispatch normally, it can also use mapDispatchToProps to bind such action creator with a short syntax, etc. The components don’t know how action creators are implemented, and you can switch between different async approaches (Redux Thunk, Redux Promise, Redux Saga) without changing the components. On the other hand, with the former, explicit approach, your components know exactly that a specific call is async, and needs dispatch to be passed by some convention (for example, as a sync parameter).

Also think about how this code will change. Say we want to have a second data loading function, and to combine them in a single action creator.

With the first approach we need to be mindful of what kind of action creator we are calling:

// action creators
function loadSomeData(dispatch, userId) {
  return fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_SOME_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_SOME_DATA_FAILURE', err })
    );
}
function loadOtherData(dispatch, userId) {
  return fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_OTHER_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_OTHER_DATA_FAILURE', err })
    );
}
function loadAllData(dispatch, userId) {
  return Promise.all(
    loadSomeData(dispatch, userId), // pass dispatch first: it's async
    loadOtherData(dispatch, userId) // pass dispatch first: it's async
  );
}


// component
componentWillMount() {
  loadAllData(this.props.dispatch, this.props.userId); // pass dispatch first
}

With Redux Thunk action creators can dispatch the result of other action creators and not even think whether those are synchronous or asynchronous:

// action creators
function loadSomeData(userId) {
  return dispatch => fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_SOME_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_SOME_DATA_FAILURE', err })
    );
}
function loadOtherData(userId) {
  return dispatch => fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_OTHER_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_OTHER_DATA_FAILURE', err })
    );
}
function loadAllData(userId) {
  return dispatch => Promise.all(
    dispatch(loadSomeData(userId)), // just dispatch normally!
    dispatch(loadOtherData(userId)) // just dispatch normally!
  );
}


// component
componentWillMount() {
  this.props.dispatch(loadAllData(this.props.userId)); // just dispatch normally!
}

With this approach, if you later want your action creators to look into current Redux state, you can just use the second getState argument passed to the thunks without modifying the calling code at all:

function loadSomeData(userId) {
  // Thanks to Redux Thunk I can use getState() here without changing callers
  return (dispatch, getState) => {
    if (getState().data[userId].isLoaded) {
      return Promise.resolve();
    }

    fetch(`http://data.com/${userId}`)
      .then(res => res.json())
      .then(
        data => dispatch({ type: 'LOAD_SOME_DATA_SUCCESS', data }),
        err => dispatch({ type: 'LOAD_SOME_DATA_FAILURE', err })
      );
  }
}

If you need to change it to be synchronous, you can also do this without changing any calling code:

// I can change it to be a regular action creator without touching callers
function loadSomeData(userId) {
  return {
    type: 'LOAD_SOME_DATA_SUCCESS',
    data: localStorage.getItem('my-data')
  }
}

So the benefit of using middleware like Redux Thunk or Redux Promise is that components aren’t aware of how action creators are implemented, and whether they care about Redux state, whether they are synchronous or asynchronous, and whether or not they call other action creators. The downside is a little bit of indirection, but we believe it’s worth it in real applications.

Finally, Redux Thunk and friends is just one possible approach to asynchronous requests in Redux apps. Another interesting approach is Redux Saga which lets you define long-running daemons (“sagas”) that take actions as they come, and transform or perform requests before outputting actions. This moves the logic from action creators into sagas. You might want to check it out, and later pick what suits you the most.

I searched the Redux repo for clues, and found that Action Creators were required to be pure functions in the past.

This is incorrect. The docs said this, but the docs were wrong.
Action creators were never required to be pure functions.
We fixed the docs to reflect that.

Use runlike from git repository https://github.com/lavie/runlike

To install runlike

pip install runlike

As it accept container id as an argument so to extract container id use following command

docker ps -a -q

You are good to use runlike to extract complete docker run command with following command

runlike <docker container ID>

The Python time.strftime docs say:

When used with the strptime() function, the %p directive only affects the output hour field if the %I directive is used to parse the hour.

Sure enough, changing your %H to %I makes it work.

I too got the same error, problem in my case is I included the column name in GROUP BY clause and it caused this error. So removed the column from GROUP BY clause and it worked!!!

Take a look at that : http://davidwalsh.name/detect-android

JavaScript:

var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
if(isAndroid) {
  // Do something!
  // Redirect to Android-site?
  window.location = 'http://android.davidwalsh.name';
}

PHP:

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if(stripos($ua,'android') !== false) { // && stripos($ua,'mobile') !== false) {
  header('Location: http://android.davidwalsh.name');
  exit();
}

Edit : As pointed out in some comments, this will work in 99% of the cases, but some edge cases are not covered. If you need a much more advanced and bulletproofed solution in JS, you should use platform.js : https://github.com/bestiejs/platform.js

Actual Answer:

The default deserializer for enums uses .name() to deserialize, so it's not using the @JsonValue. So as @OldCurmudgeon pointed out, you'd need to pass in {"event": "FORGOT_PASSWORD"} to match the .name() value.

An other option (assuming you want the write and read json values to be the same)...

More Info:

There is (yet) another way to manage the serialization and deserialization process with Jackson. You can specify these annotations to use your own custom serializer and deserializer:

@JsonSerialize(using = MySerializer.class)
@JsonDeserialize(using = MyDeserializer.class)
public final class MyClass {
    ...
}

Then you have to write MySerializer and MyDeserializer which look like this:

MySerializer

public final class MySerializer extends JsonSerializer<MyClass>
{
    @Override
    public void serialize(final MyClass yourClassHere, final JsonGenerator gen, final SerializerProvider serializer) throws IOException, JsonProcessingException
    {
        // here you'd write data to the stream with gen.write...() methods
    }

}

MyDeserializer

public final class MyDeserializer extends org.codehaus.jackson.map.JsonDeserializer<MyClass>
{
    @Override
    public MyClass deserialize(final JsonParser parser, final DeserializationContext context) throws IOException, JsonProcessingException
    {
        // then you'd do something like parser.getInt() or whatever to pull data off the parser
        return null;
    }

}

Last little bit, particularly for doing this to an enum JsonEnum that serializes with the method getYourValue(), your serializer and deserializer might look like this:

public void serialize(final JsonEnum enumValue, final JsonGenerator gen, final SerializerProvider serializer) throws IOException, JsonProcessingException
{
    gen.writeString(enumValue.getYourValue());
}

public JsonEnum deserialize(final JsonParser parser, final DeserializationContext context) throws IOException, JsonProcessingException
{
    final String jsonValue = parser.getText();
    for (final JsonEnum enumValue : JsonEnum.values())
    {
        if (enumValue.getYourValue().equals(jsonValue))
        {
            return enumValue;
        }
    }
    return null;
}

$str = preg_replace('/[\s]+/', ' ', $str);

You want to force push

What you basically want to do is to force push your local branch, in order to overwrite the remote one.

If you want a more detailed explanation of each of the following commands, then see my details section below. You basically have 4 different options for force pushing with Git:

git push <remote> <branch> -f
git push origin master -f # Example

git push <remote> -f
git push origin -f # Example

git push -f

git push <remote> <branch> --force-with-lease

If you want a more detailed explanation of each command, then see my long answers section below.

Warning: force pushing will overwrite the remote branch with the state of the branch that you're pushing. Make sure that this is what you really want to do before you use it, otherwise you may overwrite commits that you actually want to keep.

Force pushing details

Specifying the remote and branch

You can completely specify specific branches and a remote. The -f flag is the short version of --force

git push <remote> <branch> --force
git push <remote> <branch> -f

Omitting the branch

When the branch to push branch is omitted, Git will figure it out based on your config settings. In Git versions after 2.0, a new repo will have default settings to push the currently checked-out branch:

git push <remote> --force

while prior to 2.0, new repos will have default settings to push multiple local branches. The settings in question are the remote.<remote>.push and push.default settings (see below).

Omitting the remote and the branch

When both the remote and the branch are omitted, the behavior of just git push --force is determined by your push.default Git config settings:

git push --force

• As of Git 2.0, the default setting, simple, will basically just push your current branch to its upstream remote counter-part. The remote is determined by the branch's branch.<remote>.remote setting, and defaults to the origin repo otherwise.

• Before Git version 2.0, the default setting, matching, basically just pushes all of your local branches to branches with the same name on the remote (which defaults to origin).

You can read more push.default settings by reading git help config or an online version of the git-config(1) Manual Page.

Force pushing more safely with --force-with-lease

Force pushing with a "lease" allows the force push to fail if there are new commits on the remote that you didn't expect (technically, if you haven't fetched them into your remote-tracking branch yet), which is useful if you don't want to accidentally overwrite someone else's commits that you didn't even know about yet, and you just want to overwrite your own:

git push <remote> <branch> --force-with-lease

You can learn more details about how to use --force-with-lease by reading any of the following:

• git push documentation
• Git: How to ignore fast forward and revert origin [branch] to earlier commit?

You can try joda-time.

as Frank said Firebase stores sequence of values in the format of "key": "Value" which is a Map structure

to get List from this sequence you have to

1. initialize GenericTypeIndicator with HashMap of String and your Object.
2. get value of DataSnapShot as GenericTypeIndicator into Map.
3. initialize ArrayList with HashMap values.

GenericTypeIndicator<HashMap<String, Object>> objectsGTypeInd = new GenericTypeIndicator<HashMap<String, Object>>() {};
Map<String, Object> objectHashMap = dataSnapShot.getValue(objectsGTypeInd);
ArrayList<Object> objectArrayList = new ArrayList<Object>(objectHashMap.values());

Works fine for me, Hope it helps.

If you just want to print the numbers, you can avoid the loop.

# python 3
import time

startnumber = 1
endnumber = 100

# solution A without a for loop
start_time = time.clock()
m = map(str, range(startnumber, endnumber + 1))
print(' '.join(m))
end_time = time.clock()
timetaken = (end_time - start_time) * 1000
print('took {0}ms\n'.format(timetaken))

# solution B: with a for loop
start_time = time.clock()
for i in range(startnumber, endnumber + 1):
    print(i, end=' ')
end_time = time.clock()
timetaken = (end_time - start_time) * 1000
print('\ntook {0}ms\n'.format(timetaken))

You can connect with MSSMS to LocalDB. Type only in SERVER NAME: (localdb)\v11.0 and leave it by Windows Authentication and it connects to your LocalDB server and shows you the databases in it.

I have recently installed it from source and bellow are all the steps needed to install it from source with the mentioned instructions available.

Other answers already describe why those messages are shown. My answer gives a step-by-step on how to isnstall, which may help people struglling on the actual installation as I did.

1. Install Bazel

Download it from one of their available releases, for example 0.5.2. Extract it, go into the directory and configure it: bash ./compile.sh. Copy the executable to /usr/local/bin: sudo cp ./output/bazel /usr/local/bin

2. Install Tensorflow

Clone tensorflow: git clone https://github.com/tensorflow/tensorflow.git Go to the cloned directory to configure it: ./configure

It will prompt you with several questions, bellow I have suggested the response to each of the questions, you can, of course, choose your own responses upon as you prefer:

Using python library path: /usr/local/lib/python2.7/dist-packages
Do you wish to build TensorFlow with MKL support? [y/N] y
MKL support will be enabled for TensorFlow
Do you wish to download MKL LIB from the web? [Y/n] Y
Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]: 
Do you wish to use jemalloc as the malloc implementation? [Y/n] n
jemalloc disabled
Do you wish to build TensorFlow with Google Cloud Platform support? [y/N] N
No Google Cloud Platform support will be enabled for TensorFlow
Do you wish to build TensorFlow with Hadoop File System support? [y/N] N
No Hadoop File System support will be enabled for TensorFlow
Do you wish to build TensorFlow with the XLA just-in-time compiler (experimental)? [y/N] N
No XLA JIT support will be enabled for TensorFlow
Do you wish to build TensorFlow with VERBS support? [y/N] N
No VERBS support will be enabled for TensorFlow
Do you wish to build TensorFlow with OpenCL support? [y/N] N
No OpenCL support will be enabled for TensorFlow
Do you wish to build TensorFlow with CUDA support? [y/N] N
No CUDA support will be enabled for TensorFlow

3. The pip package. To build it you have to describe which instructions you want (you know, those Tensorflow informed you are missing).

Build pip script: bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both --copt=-msse4.1 --copt=-msse4.2 -k //tensorflow/tools/pip_package:build_pip_package

Build pip package: bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

Install Tensorflow pip package you just built: sudo pip install /tmp/tensorflow_pkg/tensorflow-1.2.1-cp27-cp27mu-linux_x86_64.whl

Now next time you start up Tensorflow it will not complain anymore about missing instructions.

Like this.

function printMousePos(event) {_x000D_
  document.body.textContent =_x000D_
    "clientX: " + event.clientX +_x000D_
    " - clientY: " + event.clientY;_x000D_
}_x000D_
_x000D_
document.addEventListener("click", printMousePos);

MouseEvent - MDN

MouseEvent.clientX Read only
The X coordinate of the mouse pointer in local (DOM content) coordinates.

MouseEvent.clientY Read only
The Y coordinate of the mouse pointer in local (DOM content) coordinates.

The getcode() method (Added in python2.6) returns the HTTP status code that was sent with the response, or None if the URL is no HTTP URL.

>>> a=urllib.urlopen('http://www.google.com/asdfsf')
>>> a.getcode()
404
>>> a=urllib.urlopen('http://www.google.com/')
>>> a.getcode()
200

For most cases i would prefer processes over threads. threads can be useful when you have a relatively smaller task (process overhead >> time taken by each divided task unit) and there is a need of memory sharing between them. Think a large array. Also (offtopic), note that if your CPU utilization is 100 percent or close to it, there is going to be no benefit out of multithreading or processing. (in fact it will worsen)

Here's an alternative since you don't like the cast to int:

foreach(byte b in System.Text.Encoding.UTF8.GetBytes(str.ToCharArray()))
    Console.Write(b.ToString());

map can be much faster than replace

If your dictionary has more than a couple of keys, using map can be much faster than replace. There are two versions of this approach, depending on whether your dictionary exhaustively maps all possible values (and also whether you want non-matches to keep their values or be converted to NaNs):

Exhaustive Mapping

In this case, the form is very simple:

df['col1'].map(di)       # note: if the dictionary does not exhaustively map all
                         # entries then non-matched entries are changed to NaNs

Although map most commonly takes a function as its argument, it can alternatively take a dictionary or series: Documentation for Pandas.series.map

Non-Exhaustive Mapping

If you have a non-exhaustive mapping and wish to retain the existing variables for non-matches, you can add fillna:

df['col1'].map(di).fillna(df['col1'])

as in @jpp's answer here: Replace values in a pandas series via dictionary efficiently

Benchmarks

Using the following data with pandas version 0.23.1:

di = {1: "A", 2: "B", 3: "C", 4: "D", 5: "E", 6: "F", 7: "G", 8: "H" }
df = pd.DataFrame({ 'col1': np.random.choice( range(1,9), 100000 ) })

and testing with %timeit, it appears that map is approximately 10x faster than replace.

Note that your speedup with map will vary with your data. The largest speedup appears to be with large dictionaries and exhaustive replaces. See @jpp answer (linked above) for more extensive benchmarks and discussion.

It's language specific, but in PHP :

Null means "nothing". The var has not been initialized.

False means "not true in a boolean context". Used to explicitly show you are dealing with logical issues.

0 is an int. Nothing to do with the rest above, used for mathematics.

Now, what is tricky, it's that in dynamic languages like PHP, all of them have a value in a boolean context, which (in PHP) is False.

If you test it with ==, it's testing the boolean value, so you will get equality. If you test it with ===, it will test the type, and you will get inequality.

So why are they useful ?

Well, look at the strrpos() function. It returns False if it did not found anything, but 0 if it has found something at the beginning of the string !

<?php
// pitfall :
if (strrpos("Hello World", "Hello")) { 
    // never exectuted
}

// smart move :
if (strrpos("Hello World", "Hello") !== False) {
    // that works !
}
?>

And of course, if you deal with states:

You want to make a difference between DebugMode = False (set to off), DebugMode = True (set to on) and DebugMode = Null (not set at all, will lead to hard debugging ;-)).

Your code is fine, but the problem is inside the batch file.

You have to show the content of the bat file, your problem is in the paths inside the bat file.

Try using Replace to see if it will work for you. The problem as I see it which has been mentioned a few times above is the CDate function is choking on the periods. You can use replace to change them to slashes. To answer your question about a Function in vba that can parse any date format, there is not any you have very limited options.

Dim current as Date, highest as Date, result() as Date 
For Each itemDate in DeliveryDateArray
    Dim tempDate As String
    itemDate = IIf(Trim(itemDate) = "", "0", itemDate) 'Added per OP's request.
    tempDate = Replace(itemDate, ".", "/")
    current = Format(CDate(tempDate),"dd/mm/yyyy")
    if current > highest then 
        highest = current 
    end if 
    ' some more operations an put dates into result array 
Next itemDate 
'After activating final sheet... 
Range("A1").Resize(UBound(result), 1).Value = Application.Transpose(result) 

You were setting BCC but then overwriting the variable with the FROM

$to = "[email protected]";
     $subject .= "".$emailSubject."";
 $headers .= "Bcc: ".$emailList."\r\n";
 $headers .= "From: [email protected]\r\n" .
     "X-Mailer: php";
     $headers .= "MIME-Version: 1.0\r\n";
     $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
 $message = '<html><body>';
 $message .= 'THE MESSAGE FROM THE FORM';

     if (mail($to, $subject, $message, $headers)) {
     $sent = "Your email was sent!";
     } else {
      $sent = ("Error sending email.");
     }

Ruby has no pre/post increment/decrement operator. For instance, x++ or x-- will fail to parse. More importantly, ++x or --x will do nothing! In fact, they behave as multiple unary prefix operators: -x == ---x == -----x == ...... To increment a number, simply write x += 1.

Taken from "Things That Newcomers to Ruby Should Know " (archive, mirror)

That explains it better than I ever could.

EDIT: and the reason from the language author himself (source):

1. ++ and -- are NOT reserved operator in Ruby.
2. C's increment/decrement operators are in fact hidden assignment. They affect variables, not objects. You cannot accomplish assignment via method. Ruby uses +=/-= operator instead.
3. self cannot be a target of assignment. In addition, altering the value of integer 1 might cause severe confusion throughout the program.

In addition to the accepted answer I would like to give an answer that shows how to iterate directly over the Newtonsoft collections. It uses less code and I'm guessing its more efficient as it doesn't involve converting the collections.

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
//Parse the data
JObject my_obj = JsonConvert.DeserializeObject<JObject>(your_json);

foreach (KeyValuePair<string, JToken> sub_obj in (JObject)my_obj["ADDRESS_MAP"])
{
    Console.WriteLine(sub_obj.Key);
}

I started doing this myself because JsonConvert automatically deserializes nested objects as JToken (which are JObject, JValue, or JArray underneath I think).

I think the parsing works according to the following principles:

• Every object is abstracted as a JToken

• Cast to JObject where you expect a Dictionary

• Cast to JValue if the JToken represents a terminal node and is a value

• Cast to JArray if its an array

• JValue.Value gives you the .NET type you need

Instead of foreach(), use a for() loop with a numeric index.

I had this when build my application with "All cpu" target while it referenced a 3rd party x64-only (managed) dll.

Carry Flag

The rules for turning on the carry flag in binary/integer math are two:

1. The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)

2. The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).

   • 0111 + 0001 = 1000 (carry flag is turned off [zero])
   • 1000 - 0001 = 0111 (carry flag is turned off [zero])

In unsigned arithmetic, watch the carry flag to detect errors.

In signed arithmetic, the carry flag tells you nothing interesting.

Overflow Flag

The rules for turning on the overflow flag in binary/integer math are two:

1. If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)

2. If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)

Otherwise the "overflow" flag is turned off

• 0100 + 0001 = 0101 (overflow flag is turned off)
• 0110 + 1001 = 1111 (overflow flag turned off)
• 1000 + 0001 = 1001 (overflow flag turned off)
• 1100 + 1100 = 1000 (overflow flag is turned off)

Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.

If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.

If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.

For more clarification please refer: http://teaching.idallen.com/dat2343/10f/notes/040_overflow.txt

Perhaps with dataframes one of the most easy and practical solution is:

data = dplyr::mutate(data, rownum=row_number())

Use JSON.

In the following example $php_variable can be any PHP variable.

<script type="text/javascript">
    var obj = <?php echo json_encode($php_variable); ?>;
</script>

In your code, you could use like the following:

drawChart(600/50, <?php echo json_encode($day); ?>, ...)

In cases where you need to parse out an object from JSON-string (like in an AJAX request), the safe way is to use JSON.parse(..) like the below:

var s = "<JSON-String>";
var obj = JSON.parse(s);

itoa()

Following code shows an easy way to read all phone numbers and names:

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
  String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
  String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

}
phones.close();

NOTE: getContentResolver is a method from the Activity context.

$ npm run tsc -- --init
This worked for the below package.json

  "devDependencies": {
    "@types/jasmine": "^3.6.2",
    "@types/node": "^14.14.19",
    "jasmine": "^3.6.3",
    "protractor": "^7.0.0",
    "typescript": "^4.1.3"
  },

To add a foreign key (grade_id) to an existing table (users), follow the following steps:

ALTER TABLE users ADD grade_id SMALLINT UNSIGNED NOT NULL DEFAULT 0;
ALTER TABLE users ADD CONSTRAINT fk_grade_id FOREIGN KEY (grade_id) REFERENCES grades(id);

You can use the statement :-

Class c = s.getClass();

To get the class instance.

This is how I fixed it:

IIF(ValueA != 0, Total / ValueA, 0)

It can be wrapped in an update:

SET Pct = IIF(ValueA != 0, Total / ValueA, 0)

Or in a select:

SELECT IIF(ValueA != 0, Total / ValueA, 0) AS Pct FROM Tablename;

Thoughts?

The network results at Browserscope will give you both Connections per Hostname and Max Connections for popular browsers. The data is gathered by running tests on users "in the wild," so it will stay up to date.

You could retrieve the body text of the whole page like this:

bodyText = self.driver.find_element_by_tag_name('body').text

then use an assert to check it like this:

self.assertTrue("the text you want to check for" in bodyText)

Of course, you can be specific and retrieve a specific DOM element's text and then check that instead of retrieving the whole page.

abstraction is hiding non useful data from users and encapsulation is bind together data into a capsule (a class). I think encapsulation is way that we achieve abstraction.

As a newbie, I faced the same 'problem'.

In newbie terms : when you call plot(), the graph window gets the focus and you cannot enter further commands into R. That is when you conclude that you must close the graph window to return to R. However, some commands, like identify(), act on open/active graph windows. When identify() cannot find an open/active graph window, it gives this error message.

However, you can simply click on the R window without closing the graph window. Then you can type more commands at the R prompt, like identify() etc.

public string MakeRelativePath(string workingDirectory, string fullPath)
{
    string result = string.Empty;
    int offset;

    // this is the easy case.  The file is inside of the working directory.
    if( fullPath.StartsWith(workingDirectory) )
    {
        return fullPath.Substring(workingDirectory.Length + 1);
    }

    // the hard case has to back out of the working directory
    string[] baseDirs = workingDirectory.Split(new char[] { ':', '\\', '/' });
    string[] fileDirs = fullPath.Split(new char[] { ':', '\\', '/' });

    // if we failed to split (empty strings?) or the drive letter does not match
    if( baseDirs.Length <= 0 || fileDirs.Length <= 0 || baseDirs[0] != fileDirs[0] )
    {
        // can't create a relative path between separate harddrives/partitions.
        return fullPath;
    }

    // skip all leading directories that match
    for (offset = 1; offset < baseDirs.Length; offset++)
    {
        if (baseDirs[offset] != fileDirs[offset])
            break;
    }

    // back out of the working directory
    for (int i = 0; i < (baseDirs.Length - offset); i++)
    {
        result += "..\\";
    }

    // step into the file path
    for (int i = offset; i < fileDirs.Length-1; i++)
    {
        result += fileDirs[i] + "\\";
    }

    // append the file
    result += fileDirs[fileDirs.Length - 1];

    return result;
}

This code is probably not bullet-proof but this is what I came up with. It's a little more robust. It takes two paths and returns path B as relative to path A.

example:

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\junk\\readme.txt")
//returns: "..\\..\\junk\\readme.txt"

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\foo\\bar\\docs\\readme.txt")
//returns: "docs\\readme.txt"

Simply include the Apache Commons Lang JAR and use the org.apache.commons.lang.StringUtils class. You'll notice lots of methods for replacing Strings safely and efficiently.

You can view the StringUtils API at the previously linked website.

"Don't reinvent the wheel"

In my opinion cherry-picking should be reserved for rare situations where it is required, for example if you did some fix on directly on 'master' branch (trunk, main development branch) and then realized that it should be applied also to 'maint'. You should base workflow either on merge, or on rebase (or "git pull --rebase").

Please remember that cherry-picked or rebased commit is different from the point of view of Git (has different SHA-1 identifier) than the original, so it is different than the commit in remote repository. (Rebase can usually deal with this, as it checks patch id i.e. the changes, not a commit id).

Also in git you can merge many branches at once: so called octopus merge. Note that octopus merge has to succeed without conflicts. Nevertheless it might be useful.

HTH.

Its a CORS issue, your api cannot be accessed directly from remote or different origin, In order to allow other ip address or other origins from accessing you api, you should add the 'Access-Control-Allow-Origin' on the api's header, you can set its value to '*' if you want it to be accessible to all, or you can set specific domain or ips like 'http://siteA.com' or 'http://192. ip address ';

Include this on your api's header, it may vary depending on how you are displaying json data,

if your using ajax, to retrieve and display data your header would look like this,

$.ajax({
   url: '',
   headers: {  'Access-Control-Allow-Origin': 'http://The web site allowed to access' },
   data: data,
   type: 'dataType',
   /* etc */
   success: function(jsondata){

   }
})

Hope that helps! (Updated resizeEvent, per @dmzl's answer)

Install the SharpVectors library

Install-Package SharpVectors

Add the following in XAML

<UserControl xmlns:svgc="http://sharpvectors.codeplex.com/svgc">
    <svgc:SvgViewbox Source="/Icons/icon.svg"/>
</UserControl>

After setting the sort expression on the DefaultView (table.DefaultView.Sort = "Town ASC, Cutomer ASC" ) you should loop over the table using the DefaultView not the DataTable instance itself

foreach(DataRowView r in table.DefaultView)
{
    //... here you get the rows in sorted order
    Console.WriteLine(r["Town"].ToString());
}

Using the Select method of the DataTable instead, produces an array of DataRow. This array is sorted as from your request, not the DataTable

DataRow[] rowList = table.Select("", "Town ASC, Cutomer ASC");
foreach(DataRow r in rowList)
{
    Console.WriteLine(r["Town"].ToString());
}

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

Spring Boot 1.4 introduced testing annotation called @MockBean. So now mocking and spying on Spring beans is natively supported by Spring Boot.

It's not that they were deliberately not allowed on DataTables, it's just that DataTables pre-date the IQueryable and generic IEnumerable constructs on which Linq queries can be performed.

Both interfaces require some sort type-safety validation. DataTables are not strongly typed. This is the same reason why people can't query against an ArrayList, for example.

For Linq to work you need to map your results against type-safe objects and query against that instead.

You can get Chat ID in this way.

On private chat with your bot, send a random message. You will search this message later.

Get Your API-token from bot_father : XXXXXXXXX:YYYYYYY-YYYYYYYYYYYYYYYYY_YY

Then, on your browser make a request with that url :

https://api.telegram.org/botXXXXXXXXX:YYYYYYY-YYYYYYYYYYYYYYYYY_YY/getUpdates

The request returns a json response, in json text search your random message and get chat id in that object.

for jQuery we can use below:

by input name:

$('input[name="textboxname"]').val('some value');

by input class:

$('input[type=text].textboxclass').val('some value');

by input id:

$('#textboxid').val('some value');

This is fairly straightforward. In your JS, all you would do is this or something similar:

var array = ["thing1", "thing2", "thing3"];

var parameters = {
  "array1[]": array,
  ...
};

$.post(
  'your/page.php',
  parameters
)
.done(function(data, statusText) {
    // This block is optional, fires when the ajax call is complete
});

In your php page, the values in array form will be available via $_POST['array1'].

this T-SQL code finds and prints all occurrences of pattern @p in sentence @s. you can do any processing on the sentence afterward.

declare @old_hit int = 0
declare @hit int = 0
declare @i int = 0
declare @s varchar(max)='alibcalirezaalivisualization'
declare @p varchar(max)='ali'
 while @i<len(@s)
  begin
   set @hit=charindex(@p,@s,@i)
   if @hit>@old_hit 
    begin
    set @old_hit =@hit
    set @i=@hit+1
    print @hit
   end
  else
    break
 end

the result is: 1 6 13 20

Your unit tests are considered as an environment that runs your code to test it. Just like any normal environment, you have i.e. staging/production. You may need to add a .config file for your test project as well. A workaround is to create a class library and convert it to Test Project by adding necessary NuGet packages such as NUnit and NUnit Adapter. it works perfectly fine with both Visual Studio Test Runner and Resharper and you have your app.config file in your test project.

And finally debugged my test and value from App.config:

In REST, each HTTP verbs has its place and meaning.

For example,

• GET is to get the 'resource(s)' that is pointed to in the URL.

• POST is to instructure the backend to 'create' a resource of the 'type' pointed to in the URL. You can supplement the POST operation with parameters or additional data in the body of the POST call.

In you case, since you are interested in 'getting' the info using query, thus it should be a GET operation instead of a POST operation.

This wiki may help to further clarify things.

Hope this help!

Something to be aware of, the $_SESSION variables are still set in the same page after calling session_destroy() where as this is not the case when using unset($_SESSION) or $_SESSION = array(). Also, unset($_SESSION) blows away the $_SESSION superglobal so only do this when you're destroying a session.

With all that said, it's best to do like the PHP docs has it in the first example for session_destroy().

ls | tr "" "\n"

If you are using Logback, just put this logback-test.xml file into src/test/resources directory:

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>
<root level="INFO">
    <appender-ref ref="STDOUT" />
</root>
</configuration>

Try this:

Sub GetColumns()

Dim lnRow As Long, lnCol As Long

lnRow = 3 'For testing

lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column

End Sub

Probably best not to use colIndex and rowIndex as variable names as they are already mentioned in the Excel Object Library.

if your springfox version higher than 2.5, should be add WebSecurityConfiguration as below:

@Override
public void configure(HttpSecurity http) throws Exception {
    // TODO Auto-generated method stub
    http.authorizeRequests()
        .antMatchers("/v2/api-docs", "/swagger-resources/configuration/ui", "/swagger-resources", "/swagger-resources/configuration/security", "/swagger-ui.html", "/webjars/**").permitAll()
        .and()
        .authorizeRequests()
        .anyRequest()
        .authenticated()
        .and()
        .csrf().disable();
}

To change color of selected ViewCell, there is a simple process without using custom renderer. Make Tapped event of your ViewCell as below

<ListView.ItemTemplate>
    <DataTemplate>
        <ViewCell Tapped="ViewCell_Tapped">            
        <Label Text="{Binding StudentName}" TextColor="Black" />
        </ViewCell>
    </DataTemplate>
</ListView.ItemTemplate>

In your ContentPage or .cs file, implement the event

private void ViewCell_Tapped(object sender, System.EventArgs e)
{
    if(lastCell!=null)
    lastCell.View.BackgroundColor = Color.Transparent;
    var viewCell = (ViewCell)sender;
    if (viewCell.View != null)
    {
        viewCell.View.BackgroundColor = Color.Red;
        lastCell = viewCell;
    }
} 

Declare lastCell at the top of your ContentPage like this ViewCell lastCell;

Try data = new int[] {10,20,30,40,50,60,71,80,90,91 };

I had the same error, but for me, it was attributed to having a database and a table that were named the same. When I added the ADO .NET Entity Object to my project, it misgenerated what I wanted in my database context file:

// Table
public virtual DbSet<OBJ> OBJs { get; set; }

which should've been:

public virtual DbSet<OBJ> OBJ { get; set; }

And

// Database?
public object OBJ { get; internal set; }

which I actually didn't really need, so I commented it out.

I was trying to pull in my table like this, in my controller, when I got my error:

protected Model1 db = new Model1();

public ActionResult Index()
{
    var obj =
        from p in db.OBJ
        orderby p.OBJ_ID descending
        select p;

    return View(obj);
}

I corrected my database context and all was fine, after that.

Ditto @Drew Steen on the use of theme(). Here are common theme attributes for axis text and titles.

ggplot(mtcars, aes(x = factor(cyl), y = mpg))+
  geom_point()+
  theme(axis.text.x = element_text(color = "grey20", size = 20, angle = 90, hjust = .5, vjust = .5, face = "plain"),
        axis.text.y = element_text(color = "grey20", size = 12, angle = 0, hjust = 1, vjust = 0, face = "plain"),  
        axis.title.x = element_text(color = "grey20", size = 12, angle = 0, hjust = .5, vjust = 0, face = "plain"),
        axis.title.y = element_text(color = "grey20", size = 12, angle = 90, hjust = .5, vjust = .5, face = "plain"))

Question is old, but it's never too late to answer.

$(document).ready(function() {
  //prevent drag and drop
  const yourInput = document.getElementById('inputid');
  yourInput.ondrop = e => e.preventDefault();

  //prevent paste
  const Input = document.getElementById('inputid');
  Input.onpaste = e => e.preventDefault();
});

1. Open the Connection
2. Start the server
3. open new Command prompt

Export:

mongo/bin> mongoexport -d webmitta -c domain -o domain-k.json

Import:

mongoimport -d dbname -c newCollecionname --file domain-k.json

Where

webmitta(db name)
domain(Collection Name)
domain-k.json(output file name)

I would store it as a char(36).

It looks like you just hard-coded the row and column; otherwise, a couple of small tweaks, and I think you're there:

Dim sh As Worksheet
Dim rw As Range
Dim RowCount As Integer

RowCount = 0

Set sh = ActiveSheet
For Each rw In sh.Rows

  If sh.Cells(rw.Row, 1).Value = "" Then
    Exit For
  End If

  RowCount = RowCount + 1

Next rw

MsgBox (RowCount)

If you hafe upload your file in media than:

views.py

def download_csv(request):    
    file_path = os.path.join(settings.MEDIA_ROOT, 'example-input-file.txt')    
    if os.path.exists(file_path):    
        with open(file_path, 'rb') as fh:    
            response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel")    
            response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)    
            return response

I tried to adapt @Siddhart's code to a relative path to run my open_form macro, but it didn't seem to work. Here was my first attempt. My working solution is below.

Option Explicit

Dim xlApp, xlBook
dim fso
dim curDir
set fso = CreateObject("Scripting.FileSystemObject")
curDir = fso.GetAbsolutePathName(".")
set fso = nothing

Set xlApp = CreateObject("Excel.Application")
'~~> Change Path here
Set xlBook = xlApp.Workbooks.Open(curDir & "Excels\CLIENTES.xlsb", 0, true)
xlApp.Run "open_form"
xlBook.Close
xlApp.Quit

Set xlBook = Nothing
Set xlApp = Nothing

WScript.Echo "Finished."

EDIT

I have actually worked it out, just in case someone wants to run a userform "alike" a stand alone application:

Issues I was facing:

1 - I did not want to use the Workbook_Open Event as the excel is locked in read only. 2 - The batch command is limited that the fact that (to my knowledge) it cannot call the macro.

I first wrote a macro to launch my userform while hiding the application:

Sub open_form()
 Application.Visible = False
 frmAddClient.Show vbModeless
End Sub

I then created a vbs to launch this macro (doing it with a relative path has been tricky):

dim fso
dim curDir
dim WinScriptHost
set fso = CreateObject("Scripting.FileSystemObject")
curDir = fso.GetAbsolutePathName(".")
set fso = nothing

Set xlObj = CreateObject("Excel.application")
xlObj.Workbooks.Open curDir & "\Excels\CLIENTES.xlsb"
xlObj.Run "open_form"

And I finally did a batch file to execute the VBS...

@echo off
pushd %~dp0
cscript Add_Client.vbs

Note that I have also included the "Set back to visible" in my Userform_QueryClose:

Private Sub cmdClose_Click()
Unload Me
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
    ThisWorkbook.Close SaveChanges:=True
    Application.Visible = True
    Application.Quit
End Sub

Anyway, thanks for your help, and I hope this will help if someone needs it

Use a packet analyzer to intercept the packets to/from somewhere.com. Studying those packets should tell you what is going on.

Time-outs or connections refused could mean that the remote host is too busy.

Can you provide the code where you use this.props.history.push('/Page2');?

Have you tried the goBack() method?

this.props.history.goBack();

It's listed here https://reacttraining.com/react-router/web/api/history

With a live example here https://reacttraining.com/react-router/web/example/modal-gallery

Yes, there are negative effects from this:

If you script out a change blocked by this flag you get something like the script below (all i am turning the ID column in Contact into an autonumbered IDENTITY column, but the table has dependencies). Note potential errors that can occur while the following is running:

1. Even microsoft warns that this may cause data loss (that comment is auto-generated)!
2. for a period of time, foreign keys are not enforced.
3. if you manually run this in ssms and the ' EXEC('INSERT INTO ' fails, and you let the following statements run (which they do by default, as they are split by 'go') then you will insert 0 rows, then drop the old table.
4. if this is a big table, the runtime of the insert can be large, and the transaction is holding a schema modification lock, so blocks many things.

/* To prevent any potential data loss issues, you should review this script in detail before running it outside the context of the database designer.*/

Here is an example of some SVG code I used to get three lines of vertical text into a table column heading. Other angles are possible with a bit of tweaking. I believe most browsers support SVG these days.

<svg height="150" width="40">
  <text font-weight="bold" x="-150" y="10" transform="rotate(-90 0 0)">Jane Doe</text>
  <text x="-150" y="25" transform="rotate(-90 0 0)">0/0&nbsp;&nbsp;&nbsp;&nbsp;0/0</text>
  <text x="-150" y="40" transform="rotate(-90 0 0)">2015-06-06</text>
  Sorry, your browser does not support inline SVG.
</svg>

For versions 2.23 and above only,

Instead of these suggestions, you could use git restore --staged <file> in order to unstage the file(s).

Because there are algorithms whose best-case is quick, and thus it's technically a big O, not a big Theta.

Big O is an upper bound, big Theta is an equivalence relation.

Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.

Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:] or [._:-], to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:], and I wouldn't call that unconventional.

From where did you get the idea that you need to free(token) and free(tk)? You don't. strsep() doesn't allocate memory, it only returns pointers inside the original string. Of course, those are not pointers allocated by malloc() (or similar), so free()ing them is undefined behavior. You only need to free(s) when you are done with the entire string.

Also note that you don't need dynamic memory allocation at all in your example. You can avoid strdup() and free() altogether by simply writing char *s = p;.

Make use of the very convenient and free interactive location simulator for Android phones and tablets (named CATLES). It mocks the GPS-location on a system-wide level (even within the Google Maps or Facebook apps) and it works on physical as well as virtual devices:
