For ASP.NET use WebConfigurationManager:

var config = WebConfigurationManager.OpenWebConfiguration("~/Sites/" + requestDomain + "/");
(..)
config.AppSettings.Settings["xxxx"].Value;

TLDR:First determine where in the pipeline you're getting the error from (scroll looking for screenshots of something that resembles your error), make changes to get something new, repeat.

First determine what error message you are actually seeing.

If you are seeing the file located here...

%SystemDrive%\inetpub\custerr\\500.htm

...which generally looks like this:

...then you know you are seeing the currently configured error page in **IIS ** and you do NOT need to change the ASP.net customErrors setting, asp error detail setting, or "show friendly http errors" browser setting.

You may want to look at the above referenced path instead of trusting my screenshot just in case somebody changed it.

"Yes, I see the above described error..."

In this case, you are seeing the setting of <httpErrors> or in IIS Manager it's Error Pages --> Edit Feature Settings. The default for this is errorMode=DetailedLocalOnly at the server node level (as opposed to the site level) which means that while you will see this configured error page while remote, you should be able to log on locally to the server and see the full error which should look something like this:

You should have everything that you need at that point to fix the current error.

"But I don't see the detailed error even browsing on the server"

That leaves a couple of possibilities.

1. The browser you are using on the server is configured to use a proxy in its connection settings so it is not being seen as "local".
2. You're not actually browsing to the site you think you are browsing to - this commonly happens when there's a load balancer involved. Do a ping check to see if dns gives you an IP on the server or somewhere else.
3. You're site's httpErrors settings is set for "Custom" only. Change it to "DetailedLocalOnly". However, if you have a configuration error, this may not work since the site level httpErrors is also a configuration item. In that case proceed to #4
4. The default for httpErrors for all sites is set for "Custom". In this case you need to click on the top level server node in IIS Manager (and not a particular site) and change the httpErrors settings there to DetailedLocalOnly. If this is an internal server and you're not worried about divulging sensitive information, you could also set it to "Detailed" which will allow you to see the error from clients other than the server.
5. You're missing a module on the server like UrlRewrite (this one bites me a lot, and it often gives the generic message regardless of the httpErrors settings).

"Logging on to the server is not an option for me"

Change your site's httpErrors to "Detailed" so you can see it remotely. But if it doesn't work your error might already be a config error, see #3 immediately above. So you might be stuck with #4 or #5 and you're going to need somebody from your server team.

"I'm not seeing the error page described above. I'm seeing something different"

If you see this...

...and you expect to see something like this...

...then you need to change "Send errors to browser" to true in IIS Manager, under Site --> IIS --> ASP --> Debugging Properties

If you see this...

or this...

...you need to disable friendly errors in your browser or use fiddler's webview to look at the actual response vs what your browser chooses to show you.

If you see this...

...then custom errors is working but you don't have a custom error page (of course at this point were talking about .net and not classic asp). You need to change your customErrors tag in your web.config to RemoteOnly to view on the server, or Off to view remotely.

If you see something that is styled like your site, then custom errors is likely On or RemoteOnly and it's displaying the custom page (Views->Shared->Error.cshtml in MVC for example). That said, it is unlikely but possible that somebody changed the pages in IIS for httpErrors so see the first section on that.

From your code, it looks like provider is a variant or some other variable, and not an object.

Is Nothing is for objects only, yet later you say it's a value that should either be NULL or NOT NULL, which would be handled by IsNull.

Try using:

If Not IsNull(provider) Then 
    url = url & "&provider=" & provider 
End if

Alternately, if that doesn't work, try:

If provider <> "" Then 
    url = url & "&provider=" & provider 
End if

You can always just export the HTML table to an XLS document. Excel does a pretty good job understanding HTML tables.

Another possiblitly is to export the HTML tables as a CSV or TSV file, but you would need to setup the formatting in your code. This isn't too difficult to accomplish.

There's some classes in the Microsoft.Office.Interop that allow you to create an Excel file programatically, but I have always found them to be a little clumsy. You can find a .NET version of creating a spreadsheet here, which should be pretty easy to modify for classic ASP.

As for .NET, I've always liked CarlosAG's Excel XML Writer Library. It has a nice generator so you can setup your Excel file, save it as an XML spreadsheet and it generates the code to do all the formatting and everything. I know it's not classic ASP, but I thought that I would throw it out there.

With what you're trying above, try adding the header:

"Content-Disposition", "attachment; filename=excelTest.xls"

See if that works. Also, I always use this for the content type:

  Response.ContentType = "application/octet-stream"
    Response.ContentType = "application/vnd.ms-excel"

Almost 5 years later, I think my answer can reduce a little bit the hard work of many people.

Update an element in the DOM with the HTML from the one from the ajax call can be achieved that way

$('#submitform').click(function() {
     $.ajax({
     url: "getinfo.asp",
     data: {
         txtsearch: $('#appendedInputButton').val()
     },
     type: "GET",
     dataType : "html",
     success: function (data){
         $('#showresults').html($('#showresults',data).html());
         // similar to $(data).find('#showresults')
     },
});

or with replaceWith()

// codes

success: function (data){
   $('#showresults').replaceWith($('#showresults',data));
},

You just need to replace all image network paths to byte strings in HTML string. For this first you required HtmlAgilityPack to convert Html string to Html document. https://www.nuget.org/packages/HtmlAgilityPack

Find Below code to convert each image src network path(or local path) to byte sting. It will definitely display all images with network path(or local path) in IE,chrome and firefox.

string encodedHtmlString = Emailmodel.DtEmailFields.Rows[0]["Body"].ToString();

        // Decode the encoded string.
        StringWriter myWriter = new StringWriter();
        HttpUtility.HtmlDecode(encodedHtmlString, myWriter);
        string DecodedHtmlString = myWriter.ToString();

        //find and replace each img src with byte string
         HtmlDocument document = new HtmlDocument();
         document.LoadHtml(DecodedHtmlString);
         document.DocumentNode.Descendants("img")
          .Where(e =>
        {
            string src = e.GetAttributeValue("src", null) ?? "";
            return !string.IsNullOrEmpty(src);//&& src.StartsWith("data:image");
        })
        .ToList()
                    .ForEach(x =>
                    {
                        string currentSrcValue = x.GetAttributeValue("src", null);                                
                        string filePath = Path.GetDirectoryName(currentSrcValue) + "\\";
                        string filename = Path.GetFileName(currentSrcValue);
                        string contenttype = "image/" + Path.GetExtension(filename).Replace(".", "");
                        FileStream fs = new FileStream(filePath + filename, FileMode.Open, FileAccess.Read);
                        BinaryReader br = new BinaryReader(fs);
                        Byte[] bytes = br.ReadBytes((Int32)fs.Length);
                        br.Close();
                        fs.Close();
                        x.SetAttributeValue("src", "data:" + contenttype + ";base64," + Convert.ToBase64String(bytes));                                
                    });

        string result = document.DocumentNode.OuterHtml;
        //Encode HTML string
        string myEncodedString = HttpUtility.HtmlEncode(result);

        Emailmodel.DtEmailFields.Rows[0]["Body"] = myEncodedString;

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

I personally tried many RegEx expressions without having found the perfect one that match all cases.

I think that regular expressions is hard to configure properly to match all cases properly. Although few persons will not like the namespace (and I was part of them), I propose something that is part of the .Net framework and give me proper results all the times in all cases (mainly managing every double quotes cases very well):

Microsoft.VisualBasic.FileIO.TextFieldParser

Found it here: StackOverflow

Example of usage:

TextReader textReader = new StringReader(simBaseCaseScenario.GetSimStudy().Study.FilesToDeleteWhenComplete);
Microsoft.VisualBasic.FileIO.TextFieldParser textFieldParser = new TextFieldParser(textReader);
textFieldParser.SetDelimiters(new string[] { ";" });
string[] fields = textFieldParser.ReadFields();
foreach (string path in fields)
{
    ...

Hope it could help.

the statement On Error Resume Next should be placed on top of what we want to validate.

  On Error Resume Next
  'Your code logic is here

Then end with statement like:

  If Err.Number <> 0 then

  'Your error message goes here'

  End if

I know this is way late, but for anyone else who encounters this problem: If you are using a loop of some kind (in my case, a Do-While) to display the data, make sure that you are moving to the next record (in my case, a rs.MoveNext).

I found the issue. This is a firewall message and an error was occurring in the VB script due to wrong data in database, but the error was not logged/caught properly.

this fails:

 DECLARE @vPortalUID NVARCHAR(32)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
 PRINT @nPortalUID

this works

 DECLARE @vPortalUID NVARCHAR(36)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS UNIQUEIDENTIFIER)
 PRINT @nPortalUID

the difference is NVARCHAR(36), your input parameter is too small!

The reject actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject() the exception value is undefined, hence the "undefined" part in the error that you get.

You do not show the code that uses the promise, but I reckon it is something like this:

var promise = doSth();
promise.then(function() { doSthHere(); });

Try adding an empty failure call, like this:

promise.then(function() { doSthHere(); }, function() {});

This will prevent the error to appear.

However, I would consider calling reject only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.

Some of the solutions listed on this page have some side-effects:

1. affect the position of the key in the object, adding it to the bottom (if this matters to you)
2. would not work in IE9+ (again, if this matters to you)

Here is a solution which keeps the position of the key in the same place and is compatible in IE9+, but has to create a new object and may not be the fastest solution:

function renameObjectKey(oldObj, oldName, newName) {
    const newObj = {};

    Object.keys(oldObj).forEach(key => {
        const value = oldObj[key];

        if (key === oldName) {
            newObj[newName] = value;
        } else {
            newObj[key] = value;
        }
    });

    return newObj;
}

Please note: IE9 may not support forEach in strict mode

Place this line before the closing script tag,writing from memory:

i think the question is how to call the javascript function on pageload

The problem with this is that when the SQL engine goes to evaluate the expression, it checks the FROM portion to pull the proper tables, and then the WHERE portion to provide some base criteria, so it cannot properly evaluate a dynamic condition on which column to check against.

You can use a WHERE clause when you're checking the WHERE criteria in the predicate, such as

WHERE account_location = CASE @locationType
                              WHEN 'business' THEN 45
                              WHEN 'area' THEN 52
                         END

so in your particular case, you're going to need put the query into a stored procedure or create three separate queries.

Another option, if you prefer, would be to get the DOM element from the jQuery object and use standard DOM accessors on it:

$("#myElement")[0].title = "new title value";

The "jQuery way", as mentioned by others, is to use the attr() method. See the API documentation for attr() here.

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

3 steps: Consume all the white spaces, check if is a line, consume all the nonwhitespace.3

while(true){

    // consume whitespaces
    while(isspace(c)){ inFile.read() }
    if (c == '\n'){ numberLines++; continue; }
    while (!isspace(c)){
         numberChars++;
         c = inFile.read();
    }
    numberWords++;
}

With EF Core in .NET Core you can use the keyword ThenInclude :

return DatabaseContext.Applications
 .Include(a => a.Children).ThenInclude(c => c.ChildRelationshipType);

Include childs from childrens collection :

return DatabaseContext.Applications
 .Include(a => a.Childrens).ThenInclude(cs => cs.ChildRelationshipType1)
 .Include(a => a.Childrens).ThenInclude(cs => cs.ChildRelationshipType2);

If you are using Python2.6 or newer, it's convenient to use socket.create_connection

sock = socket.create_connection(address, timeout=10)
sock.settimeout(None)
fileobj = sock.makefile('rb', 0)

Arrays.sort(yourArray)

will do the job perfectly

Unless someone can recommend a free tool to do this, you can achieve this with ReSharper:

ReSharper >> Options... >> Languages/C# >> Line Breaks and Wrapping

• Check "Wrap long lines"
• Set "Right Margin (columns)" to the required value (default is 120)

Hope that helps.

Base 64 Representation of SHA1 Hash:

String hashedVal = Base64.getEncoder().encodeToString(DigestUtils.sha1(stringValue.getBytes(Charset.forName("UTF-8"))));

What you're seeing is integer division. To get floating point division by default,

from __future__ import division

Or, you could convert 1 or 2 of 1/2 into a floating point value.

sqrt = x**(1.0/2)

Install the additional module tablefunc once per database, which provides the function crosstab(). Since Postgres 9.1 you can use CREATE EXTENSION for that:

CREATE EXTENSION IF NOT EXISTS tablefunc;

Improved test case

CREATE TABLE tbl (
   section   text
 , status    text
 , ct        integer  -- "count" is a reserved word in standard SQL
);

INSERT INTO tbl VALUES 
  ('A', 'Active', 1), ('A', 'Inactive', 2)
, ('B', 'Active', 4), ('B', 'Inactive', 5)
                    , ('C', 'Inactive', 7);  -- ('C', 'Active') is missing

Simple form - not fit for missing attributes

crosstab(text) with 1 input parameter:

SELECT *
FROM   crosstab(
   'SELECT section, status, ct
    FROM   tbl
    ORDER  BY 1,2'  -- needs to be "ORDER BY 1,2" here
   ) AS ct ("Section" text, "Active" int, "Inactive" int);

Returns:

 Section | Active | Inactive
---------+--------+----------
 A       |      1 |        2
 B       |      4 |        5
 C       |      7 |           -- !!

• No need for casting and renaming.
• Note the incorrect result for C: the value 7 is filled in for the first column. Sometimes, this behavior is desirable, but not for this use case.
• The simple form is also limited to exactly three columns in the provided input query: row_name, category, value. There is no room for extra columns like in the 2-parameter alternative below.

Safe form

crosstab(text, text) with 2 input parameters:

SELECT *
FROM   crosstab(
   'SELECT section, status, ct
    FROM   tbl
    ORDER  BY 1,2'  -- could also just be "ORDER BY 1" here

  , $$VALUES ('Active'::text), ('Inactive')$$
   ) AS ct ("Section" text, "Active" int, "Inactive" int);

Returns:

 Section | Active | Inactive
---------+--------+----------
 A       |      1 |        2
 B       |      4 |        5
 C       |        |        7  -- !!

• Note the correct result for C.

• The second parameter can be any query that returns one row per attribute matching the order of the column definition at the end. Often you will want to query distinct attributes from the underlying table like this:

  'SELECT DISTINCT attribute FROM tbl ORDER BY 1'
  

  That's in the manual.

  Since you have to spell out all columns in a column definition list anyway (except for pre-defined crosstabN() variants), it is typically more efficient to provide a short list in a VALUES expression like demonstrated:

  $$VALUES ('Active'::text), ('Inactive')$$)
  

  Or (not in the manual):

  $$SELECT unnest('{Active,Inactive}'::text[])$$  -- short syntax for long lists
  

• I used dollar quoting to make quoting easier.

• You can even output columns with different data types with crosstab(text, text) - as long as the text representation of the value column is valid input for the target type. This way you might have attributes of different kind and output text, date, numeric etc. for respective attributes. There is a code example at the end of the chapter crosstab(text, text) in the manual.

db<>fiddle here

Advanced examples

• Pivot on Multiple Columns using Tablefunc - also demonstrating mentioned "extra columns"

• Dynamic alternative to pivot with CASE and GROUP BY

\crosstabview in psql

Postgres 9.6 added this meta-command to its default interactive terminal psql. You can run the query you would use as first crosstab() parameter and feed it to \crosstabview (immediately or in the next step). Like:

db=> SELECT section, status, ct FROM tbl \crosstabview

Similar result as above, but it's a representation feature on the client side exclusively. Input rows are treated slightly differently, hence ORDER BY is not required. Details for \crosstabview in the manual. There are more code examples at the bottom of that page.

Related answer on dba.SE by Daniel Vérité (the author of the psql feature):

• How do I generate a pivoted CROSS JOIN where the resulting table definition is unknown?

The previously accepted answer is outdated.

• The variant of the function crosstab(text, integer) is outdated. The second integer parameter is ignored. I quote the current manual:

  crosstab(text sql, int N) ...

  Obsolete version of crosstab(text). The parameter N is now ignored, since the number of value columns is always determined by the calling query

• Needless casting and renaming.

• It fails if a row does not have all attributes. See safe variant with two input parameters above to handle missing attributes properly.

• ORDER BY is required in the one-parameter form of crosstab(). The manual:

  In practice the SQL query should always specify ORDER BY 1,2 to ensure that the input rows are properly ordered

Here is my solution:

public String HMAC_SHA256(String secret, String message)
{
    String hash="";
    try{
        Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
        SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(), "HmacSHA256");
        sha256_HMAC.init(secret_key);

        hash = Base64.encodeToString(sha256_HMAC.doFinal(message.getBytes()), Base64.DEFAULT);
    }catch (Exception e)
    {

    }
    return hash.trim();
}

As a general rule:

Double representation is good enough in most cases but can miserably fail in some situations. Use decimal values if you need complete precision (as in financial applications).

Most problems with doubles doesn't come from direct comparison, it use to be a result of the accumulation of several math operations which exponentially disturb the value due to rounding and fractional errors (especially with multiplications and divisions).

Check your logic, if the code is:

x = 0.1

if (x == 0.1)

it should not fail, it's to simple to fail, if X value is calculated by more complex means or operations it's quite possible the ToString method used by the debugger is using an smart rounding, maybe you can do the same (if that's too risky go back to using decimal):

if (x.ToString() == "0.1")

you can use the below code to bring focus to a div, in this example the page scrolls to the <div id="navigation">

$('html, body').animate({ scrollTop: $('#navigation').offset().top }, 'slow');

select Name, Value, AnotherColumn
from out_pumptable
where Value =
(
  select Max(Value)
  from out_pumptable as f where f.Name=out_pumptable.Name
)
group by Name, Value, AnotherColumn

Try like this, It works.

I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

You can't do it without a full CSV parser.

In VB2008, it works this way:

Project>Add References

Then click on the Recent tab where you can see list of references used recently. Locate the one you do not want and delet it. Then you close without adding anything.

Have you installed it?

On debian/ubuntu:

aptitude install python-numpy

On windows:

http://sourceforge.net/projects/numpy/files/NumPy/

On other systems:

http://sourceforge.net/projects/numpy/files/NumPy/

$ tar xfz numpy-n.m.tar.gz
$ cd numpy-n.m
$ python setup.py install

>>> class Test:
...     def __repr__(self):
...         return "Test()"
...     def __str__(self):
...         return "member of Test"
... 
>>> t = Test()
>>> t
Test()
>>> print(t)
member of Test

The __str__ method is what happens when you print it, and the __repr__ method is what happens when you use the repr() function (or when you look at it with the interactive prompt). If this isn't the most Pythonic method, I apologize, because I'm still learning too - but it works.

If no __str__ method is given, Python will print the result of __repr__ instead. If you define __str__ but not __repr__, Python will use what you see above as the __repr__, but still use __str__ for printing.

I run this snippet of code every time I go to read the properties file, only actually reading the file if it has been modified since the last time I read it. Hope this helps someone.

private long timeStamp;
private File file;

private boolean isFileUpdated( File file ) {
  this.file = file;
  this.timeStamp = file.lastModified();

  if( this.timeStamp != timeStamp ) {
    this.timeStamp = timeStamp;
    //Yes, file is updated
    return true;
  }
  //No, file is not updated
  return false;
}

Similar approach is used in Log4J FileWatchdog.

why You don't use Ajax to

its simple and does not require page refresh and has success and error callbacks

take look at my samlpe

<a id="ResendVerificationCode" >@Resource_en.ResendVerificationCode</a>

and in JQuery

 $("#ResendVerificationCode").on("click", function() {
                getUserbyPhoneIfNotRegisterd($("#phone").val());
 });

and this is my ajax which call my controller and my controller and return object from database

function getUserbyPhoneIfNotRegisterd(userphone) {

              $.ajax({
                    type: "GET",
                    dataType: "Json",
                    url: '@Url.Action("GetUserByPhone", "User")' + '?phone=' + userphone,
                    async: false,
                    success: function(data) {
                        if (data == null || data.data == null) {
                            ErrorMessage("", "@Resource_en.YourPhoneDoesNotExistInOurDatabase");
                        } else {
                            user = data[Object.keys(data)[0]];
                                AddVereCode(user.ID);// anather Ajax call 
                                SuccessMessage("Done", "@Resource_en.VerificationCodeSentSuccessfully", "Done");
                        }
                    },
                    error: function() {
                        ErrorMessage("", '@Resource_en.ErrorOccourd');
                    }
                });
            }

You have various possibilies. The most simple and the most ugly is:

XAML

<Button Name="cmdCommand" Click="Button_Clicked" Content="Command"/> 

Code Behind

private void Button_Clicked(object sender, RoutedEventArgs e) { 
    FrameworkElement fe=sender as FrameworkElement;
    ((YourClass)fe.DataContext).DoYourCommand();     
} 

Another solution (better) is to provide a ICommand-property on your YourClass. This command will have already a reference to your YourClass-object and therefore can execute an action on this class.

XAML

<Button Name="cmdCommand" Command="{Binding YourICommandReturningProperty}" Content="Command"/>

Because during writing this answer, a lot of other answers were posted, I stop writing more. If you are interested in one of the ways I showed or if you think I have made a mistake, make a comment.

You need to create an API : Your js functions execute AJAX requests on your web service

  var mult = function(arg1, arg2)
    $.ajax({
      url: "webservice.php?action=mult&arg1="+arg1+"&arg2="+arg2
    }).done(function(data) {
      console.log(data);
    });
  }

on the php side, you'll have to check the action parameter in order to execute the propre function (basically a switch statement on the $_GET["action"] variable)

tSql escapes a double quote with another double quote. So if you wanted it to be part of your sql string literal you would do this:

declare @xml xml 
set @xml = "<transaction><item value=""hi"" /></transaction>"

If you want to include a quote inside a value in the xml itself, you use an entity, which would look like this:

declare @xml xml
set @xml = "<transaction><item value=""hi &quot;mom&quot; lol"" /></transaction>"

Determine what the User Agent is for the devices that you need to simulate and then test a variable against that.

for example:

// var userAgent = navigator.userAgent.toLowerCase(); // this would actually get the user agent

var userAgent = "iphone"; /* Simulates User Agent for iPhone */
if (userAgent.indexOf('iphone') != -1) {
   // some code here
}

For finding value use below

if let a = companies["AAPL"] {
   // a is the value
}

For traversing through the dictionary

for (key, value) in companies {
    print(key,"---", value)
}

Finally for searching key by value you firstly add the extension

extension Dictionary where Value: Equatable {
    func findKey(forValue val: Value) -> Key? {
        return first(where: { $1 == val })?.key
    }
}

Then just call

companies.findKey(val : "Apple Inc")

If you go to Internet Explorer, Tools, Internet Option, Security, Custom, find the "Include local directory path When uploading files to a server" (it is quite a ways down) and click on "Enable" . This will work

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

FOR is essentially iterating over the "lines" in the data set. In this case, there is one line that contains the path. The "delims=;" is just telling it to separate on semi-colons. If you change the body to echo %%g,%%h,%%i,%%j,%%k you'll see that it is treating the input as a single line and breaking it into multiple tokens.

I had the same task recently and I used the following for sql server 2012 db. Use management studio and connect to the database you want to search. Then execute the following script.

Select 
[tgr].[name] as [trigger name], 
[tbl].[name] as [table name]

from sysobjects tgr 

join sysobjects tbl
on tgr.parent_obj = tbl.id

WHERE tgr.xtype = 'TR'

If you need a permanent solution for keeping Python cache files out of your project directories:

Starting with Python 3.8 you can use the environment variable PYTHONPYCACHEPREFIX to define a cache directory for Python.

From the Python docs:

If this is set, Python will write .pyc files in a mirror directory tree at this path, instead of in pycache directories within the source tree. This is equivalent to specifying the -X pycache_prefix=PATH option.

Example

If you add the following line to your ./profile in Linux:

export PYTHONPYCACHEPREFIX="$HOME/.cache/cpython/"

Python won't create the annoying __pycache__ directories in your project directory, instead it will put all of them under ~/.cache/cpython/

Set 2 properties below:

1. extendedState = 6
2. resizeable = true

It works for me.

Rather than Null Object Pattern -- which has its uses -- you might consider situations where the null object is a bug.

When the exception is thrown, examine the stack trace and work through the bug.

None of the above worked for me.

In my case, I needed to add the following to the user control I had created:

display:inline-block;

You can do this in the Admin section. It's explained in the documentation.

https://docs.djangoproject.com/en/dev/ref/contrib/redirects/

A wrapper class java.lang.Long can store 10 digit easily.

   Long phoneNumber = 1234567890;

It can store more than that also.

Documentation:

public final class Long extends Number implements Comparable<Long> {
    /**
     * A constant holding the minimum value a {@code long} can
     * have, -2<sup>63</sup>.
     */
    @Native public static final long MIN_VALUE = 0x8000000000000000L;

    /**
     * A constant holding the maximum value a {@code long} can
     * have, 2<sup>63</sup>-1.
     */
    @Native public static final long MAX_VALUE = 0x7fffffffffffffffL;
}

This means it can store values of range 9,223,372,036,854,775,807 to -9,223,372,036,854,775,808.

You can write a generator function that returns date objects starting from today:

import datetime

def date_generator():
  from_date = datetime.datetime.today()
  while True:
    yield from_date
    from_date = from_date - datetime.timedelta(days=1)

This generator returns dates starting from today and going backwards one day at a time. Here is how to take the first 3 dates:

>>> import itertools
>>> dates = itertools.islice(date_generator(), 3)
>>> list(dates)
[datetime.datetime(2009, 6, 14, 19, 12, 21, 703890), datetime.datetime(2009, 6, 13, 19, 12, 21, 703890), datetime.datetime(2009, 6, 12, 19, 12, 21, 703890)]

The advantage of this approach over a loop or list comprehension is that you can go back as many times as you want.

Edit

A more compact version using a generator expression instead of a function:

date_generator = (datetime.datetime.today() - datetime.timedelta(days=i) for i in itertools.count())

Usage:

>>> dates = itertools.islice(date_generator, 3)
>>> list(dates)
[datetime.datetime(2009, 6, 15, 1, 32, 37, 286765), datetime.datetime(2009, 6, 14, 1, 32, 37, 286836), datetime.datetime(2009, 6, 13, 1, 32, 37, 286859)]

Although you can run FTP commands using WebSockets, the simpler solution is listing your files using opendir in server side (PHP), and "spitting" it into the HTML source-code, so it will be available to client side.

The following code will do just that,

Optionally -

• use <a> tag to present a link.

• query for more information using server side (PHP),

  for example a file size,

_{PHP filesize TIP:   also you can easily overcome the 2GB limit of PHP's filesize using: AJAX + HEAD request + .htaccess rule to allow Content-Length access from client-side.}

• The following is a trimmed-down (simplified) example:

<?php
  /* taken from: https://github.com/eladkarako/download.eladkarako.com */

  $path = 'resources';
  $files = [];
  $handle = @opendir('./' . $path . '/');

  while ($file = @readdir($handle)) 
    ("." !== $file && ".." !== $file) && array_push($files, $file);
  @closedir($handle);
  sort($files); //uksort($files, "strnatcasecmp");

  $files = json_encode($files);

  unset($handle,$ext,$file,$path);

This is because the current user is not permitted to write in that path. So, to change r/w (read/write) permissions you can either use 1. terminal, or 2. Graphical "Get Info" window.

1. Using Terminal

Google how to use chmod/chown (change mode/change owner) commands from terminal

2. Using graphical 'Get Info'

You can right click on the folder/file you want to change permissions of, then open Get Info which will show you a window like below at the bottom of which you can easily change r/w permissions:

Remember to change the permission back to "read only" after your temporary work, if possible

In case, if you want to do some job on the selection of one of the radio buttons (without having any additional OK button or something), your code is fine, updated little.

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RadioGroup rg = (RadioGroup) findViewById(R.id.radioGroup1);

        rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() 
        {
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch(checkedId){
                    case R.id.radio0:
                        // do operations specific to this selection
                        break;
                    case R.id.radio1:
                        // do operations specific to this selection
                        break;
                    case R.id.radio2:
                        // do operations specific to this selection
                        break;
                }   
            }
        });
    }
}

Can't you just try to replace the body content with the document.body handler?

if your page is this:

<html>
<body>
blablabla
<script type="text/javascript">
document.body.innerHTML="hi!";
</script>
</body>
</html>

Just use the document.body to replace the body.

This works for me. All the content of the BODY tag is replaced by the innerHTML you specify. If you need to even change the html tag and all childs you should check out which tags of the 'document.' are capable of doing so.

An example with javascript scripting inside it:

<html>
<body>
blablabla
<script type="text/javascript">
var changeme = "<button onClick=\"document.bgColor = \'#000000\'\">click</button>";
document.body.innerHTML=changeme;
</script>
</body>

This way you can do javascript scripting inside the new content. Don't forget to escape all double and single quotes though, or it won't work. escaping in javascript can be done by traversing your code and putting a backslash in front of all singe and double quotes.

Bare in mind that server side scripting like php doesn't work this way. Since PHP is server-side scripting it has to be processed before a page is loaded. Javascript is a language which works on client-side and thus can not activate the re-processing of php code.

I think the problem is with the spaces. I had my variable at the System variables but it didn't work. When I changed variable Progra~1 = 'Program Files' everything works fine.

M2_HOME C:\Progra~1\Maven\apache-maven-3.1.1

I also moved my M2_HOME at the end of the PATH(%M2_HOME%\bin) I'm not sure if this has any difference.

Yes, once you have joined the iPhone Developer Program, and paid Apple $99, you can provision your applications on up to 100 iOS devices.

If an Immutable/Singleton collections refers to the one which having only one object and which is not further gets modified, then the same functionality can be achieved by making a collection "UnmodifiableCollection" having only one object. Since the same functionality can be achieved by Unmodifiable Collection with one object, then what special purpose the Singleton Collection serves for?

Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless:

• the field's tag is "-", or
• the field is empty and its tag specifies the "omitempty" option.

The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options.

Bootstrap offers various table styles. Have a look at Base CSS - Tables for documentation and examples.

The following style gives great looking tables:

<table class="table table-striped table-bordered table-condensed">
  ...
</table>

update Hotels set Discount=30 where Hotelid >= 1 and Hotelid <= 5504

a <- 1:120
b <- a[seq(1, length(a), 6)]

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

You can find it from INFORMATION_SCHEMA.COLUMNS by column_name filter

Select DISTINCT TABLE_NAME as TableName,COLUMN_NAME as ColumnName
     From INFORMATION_SCHEMA.COLUMNS Where column_name like '%myname%'

try with

<form formGroup="userForm">

instead of

<form [formGroup]="userForm">

Very easy trick is using a CSS calc formula. All modern browsers, IE9, wide range of mobile browsers should support this.

<div style='white-space:nowrap'>
  <span style='display:inline-block;width:80px;font-weight:bold'>
    <label for='field1'>Field1</label>
  </span>
  <input id='field1' name='field1' type='text' value='Some text' size='30' style='width:calc(100% - 80px)' />
</div>

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

There is comma missing in your tuple.

insert the comma between the tuples as shown:

pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))

Do the same for all

In our case it ended up being a Kerberos issue. I followed the steps in this article to resolve the issue: https://techcommunity.microsoft.com/t5/SQL-Server-Support/Bulk-Insert-and-Kerberos/ba-p/317304.

It came down to configuring delegation on the machine account of the SQL Server where the BULK INSERT statement is running. The machine account needs to be able to delegate via the "cifs" service to the file server where the files are located. If you are using constrained delegation make sure to specify "Use any authenication protocol".

If DFS is involved you can execute the following Powershell command to get the name of the file server:

Get-DfsnFolderTarget -Path "\\dfsnamespace\share"

this.button2.BaseColor = System.Drawing.Color.FromArgb(((int)(((byte)(29)))), ((int)(((byte)(190)))), ((int)(((byte)(149)))));

Have you tried adding this to your routes file instead Route::get('user', "user@index")?

The piece of text before the @, user in this case, will direct the page to the user controller and the piece of text after the @, index, will direct the script to the user function public function get_index().

I see you're using $restful, in which case you could set your Route to Route::any('user', 'user@index'). This will handle both POST and GET, instead of writing them both out separately.

Try the following command sequence:

$ git fetch origin <copy/past commit sha1 here>
$ git checkout FETCH_HEAD
$ git push origin master

The span elements are inline an thus don't break the flow of the paragraph, only style in between the tags.

On newer versions of Symfony2 (using a parameters.yml instead of parameters.ini), you can store objects or arrays instead of key-value pairs, so you can manage your globals this way:

config.yml (edited only once):

# app/config/config.yml
twig:
  globals:
    project: %project%

parameters.yml:

# app/config/parameters.yml
project:
  name:       myproject.com
  version:    1.1.42

And then in a twig file, you can use {{ project.version }} or {{ project.name }}.

Note: I personally dislike adding things to app, just because that's the Symfony's variable and I don't know what will be stored there in the future.

fastest way is to use the .is() jQuery function.

if ( $('input').is('[readonly]') ) { }

using [readonly] as a selector simply checks if the attribute is defined on your element. if you want to check for a value, you can use something like this instead:

if ( $('input').is('[readonly="somevalue"]') ) { }

This is the class I came up with in the end:

Here are some differences:

1. You can call app.render on root level and res.render only inside a route/middleware.

2. app.render always returns the html in the callback function, whereas res.render does so only when you've specified the callback function as your third parameter. If you call res.render without the third parameter/callback function the rendered html is sent to the client with a status code of 200.

   Take a look at the following examples.

   • app.render

     app.render('index', {title: 'res vs app render'}, function(err, html) {
         console.log(html)
     });
     
     // logs the following string (from default index.jade)
     <!DOCTYPE html><html><head><title>res vs app render</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>res vs app render</h1><p>Welcome to res vs app render</p></body></html>
     

   • res.render without third parameter

     app.get('/render', function(req, res) {
         res.render('index', {title: 'res vs app render'})
     })
     
     // also renders index.jade but sends it to the client 
     // with status 200 and content-type text/html on GET /render
     

   • res.render with third parameter

     app.get('/render', function(req, res) {
         res.render('index', {title: 'res vs app render'}, function(err, html) {
             console.log(html);
             res.send('done');
         })
     })
     
     // logs the same as app.render and sends "done" to the client instead 
     // of the content of index.jade
     

3. res.render uses app.render internally to render template files.

4. You can use the render functions to create html emails. Depending on your structure of your app, you might not always have acces to the app object.

   For example inside an external route:

   app.js

   var routes = require('routes');
   
   app.get('/mail', function(req, res) {
       // app object is available -> app.render
   })
   
   app.get('/sendmail', routes.sendmail);
   

   ---

   routes.js

   exports.sendmail = function(req, res) {
       // can't use app.render -> therefore res.render
   }

        Place some large content here
    </div>
    </form>
</body>
</html>

I did it one time with a workaround, hope it helps.

string fullName = typeof(MyObj).FullName;

switch (fullName)
{
    case "fullName1":
    case "fullName2":
    case "fullName3":
}

Per Martin Konicek's comment, to fully disable the selection of the items in the simplest manner:

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="Focusable" Value="false"/>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

However if you still require the functionality of the ListView, like being able to select an item, then you can visually disable the styling of the selected item like so:

You can do this a number of ways, from changing the ListViewItem's ControlTemplate to just setting a style (much easier). You can create a style for the ListViewItems using the ItemContainerStyle and 'turn off' the background and border brush when it is selected.

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="IsSelected"
                         Value="True">
                    <Setter Property="Background"
                            Value="{x:Null}" />
                    <Setter Property="BorderBrush"
                            Value="{x:Null}" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

Also, unless you have some other way of notifying the user when the item is selected (or just for testing) you can add a column to represent the value:

<GridViewColumn Header="IsSelected"
                DisplayMemberBinding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem}}, Path=IsSelected}" />

Just a note that in Java 9 and above, the naming convention is different. System.getProperty("java.version") returns "9" rather than "1.9".

I need the collection length to decide whether I should render table <thead></thead>

but don't know why @Django 2.1.7 the chosen answer will fail(empty) my forloop afterward.

I got to use {% if forloop.first %} {% endif %} to overcome:

<table>
    {% for record in service_list %}
        {% if forloop.first %}
            <thead>
            <tr>
                <th>??</th>
            </tr>
            </thead>
        {% endif %}
        <tbody>
        <tr>
            <td>{{ record.date }}</td>
        </tr>
    {% endfor %}
    </tbody>
</table>

tldr; fetch the file from the url, store it as a local Blob, inject a link element into the DOM, and click it to download the Blob

I had a PDF file that was stored in S3 behind a Cloudfront URL. I wanted the user to be able to click a button and immediately initiate a download without popping open a new tab with a PDF preview. Generally, if a file is hosted at a URL that has a different domain that the site the user is currently on, immediate downloads are blocked by many browsers for user security reasons. If you use this solution, do not initiate the file download unless a user clicks on a button to intentionally download.

In order to get by this, I needed to fetch the file from the URL getting around any CORS policies to save a local Blob that would then be the source of the downloaded file. In the code below, make sure you swap in your own fileURL, Content-Type, and FileName.

fetch('https://cors-anywhere.herokuapp.com/' + fileURL, {
    method: 'GET',
    headers: {
      'Content-Type': 'application/pdf',
    },
  })
  .then((response) => response.blob())
  .then((blob) => {
    // Create blob link to download
    const url = window.URL.createObjectURL(
      new Blob([blob]),
    );
    const link = document.createElement('a');
    link.href = url;
    link.setAttribute(
      'download',
      `FileName.pdf`,
    );

    // Append to html link element page
    document.body.appendChild(link);

    // Start download
    link.click();

    // Clean up and remove the link
    link.parentNode.removeChild(link);
  });

This solution references solutions to getting a blob from a URL and using a CORS proxy.

Update As of January 31st, 2021, the cors-anywhere demo hosted on Heroku servers will only allow limited use for testing purposes and cannot be used for production applications. You will have to host your own cors-anywhere server by following cors-anywhere or cors-server.

for foo in *.gz
do
  tar xf "$foo"
  rm "$foo"
done

Don't define variables in headers. Put declarations in header and definitions in one of the .c files.

In config.h

extern const char *names[];

In some .c file:

const char *names[] =
    {
        "brian", "stefan", "steve"
    };

If you put a definition of a global variable in a header file, then this definition will go to every .c file that includes this header, and you will get multiple definition error because a varible may be declared multiple times but can be defined only once.

There's no need for the outer try in your example, so you can at least go down from 3 to 2, and also you don't need closing ; at the end of the resource list. The advantage of using two try blocks is that all of your code is present up front so you don't have to refer to a separate method:

public List<User> getUser(int userId) {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    List<User> users = new ArrayList<>();
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = con.prepareStatement(sql)) {
        ps.setInt(1, userId);
        try (ResultSet rs = ps.executeQuery()) {
            while(rs.next()) {
                users.add(new User(rs.getInt("id"), rs.getString("name")));
            }
        }
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return users;
}

You used %H (24 hour format) instead of %I (12 hour format).

Pylint message control is documented in the Pylint manual:

Is it possible to locally disable a particular message?

Yes, this feature has been added in Pylint 0.11. This may be done by adding # pylint: disable=some-message,another-one at the desired block level or at the end of the desired line of code.

You can use the message code or the symbolic names.

For example,

def test():
    # Disable all the no-member violations in this function
    # pylint: disable=no-member
    ...

global VAR # pylint: disable=global-statement

The manual also has further examples.

There is a wiki that documents all Pylint messages and their codes.

Merge squash merges a tree (a sequence of commits) into a single commit. That is, it squashes all changes made in n commits into a single commit.

Rebasing is re-basing, that is, choosing a new base (parent commit) for a tree. Maybe the mercurial term for this is more clear: they call it transplant because it's just that: picking a new ground (parent commit, root) for a tree.

When doing an interactive rebase, you're given the option to either squash, pick, edit or skip the commits you are going to rebase.

Hope that was clear!

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

In the W3 wiki page about structuring HTML5, it says:

<section>: Used to either group different articles into different purposes or subjects, or to define the different sections of a single article.

And then displays an image that I cleaned up:

It also describes how to use the <article> tag (from same W3 link above):

<article> is related to <section>, but is distinctly different. Whereas <section> is for grouping distinct sections of content or functionality, <article> is for containing related individual standalone pieces of content, such as individual blog posts, videos, images or news items. Think of it this way - if you have a number of items of content, each of which would be suitable for reading on their own, and would make sense to syndicate as separate items in an RSS feed, then <article> is suitable for marking them up.

In our example, <section id="main"> contains blog entries. Each blog entry would be suitable for syndicating as an item in an RSS feed, and would make sense when read on its own, out of context, therefore <article> is perfect for them:

<section id="main">
    <article>
      <!-- first blog post -->
    </article>

    <article>
      <!-- second blog post  -->
    </article>

    <article>
      <!-- third blog post -->
    </article>
</section>

Simple huh? Be aware though that you can also nest sections inside articles, where it makes sense to do so. For example, if each one of these blog posts has a consistent structure of distinct sections, then you could put sections inside your articles as well. It could look something like this:

<article>
  <section id="introduction">
  </section>

  <section id="content">
  </section>

  <section id="summary">
  </section>
</article>

not() is a function in xpath (as opposed to an operator), so

//a[not(contains(@id, 'xx'))]

I had the same problem with Tensorflow 2.0.0 in PyCharm. PyCharm did not recognize tensorflow.keras; I updated my PyCharm and the problem was resolved!

1. Open your files in windows notebook
2. Change the encoding to be an UTF-8 encoding
3. Save your file
4. Try again! :O)

Check out this implementation of PHP's strtotime() in JavaScript!

I found that it works identically to PHP for everything that I threw at it.

Update: this function as per version 1.0.2 can't handle this case: '2007:07:20 20:52:45' (Note the : separator for year and month)

Update 2018:

This is now available as an npm module! Simply npm install locutus and then in your source:

var strtotime = require('locutus/php/datetime/strtotime');

If anyone else gets here because they're trying to set up a Jenkins slave, then you need to set the url of the host to the one it's actually using.

On the host, go to Manage Jenkins > Configure System and edit "Jenkins URL"

Alexander Pavlov's answer gets the closest to what you want.

Due to the extensiveness of jQuery's abstraction and functionality, a lot of hoops have to be jumped in order to get to the meat of the event. I have set up this jsFiddle to demonstrate the work.

1. Setting up the Event Listener Breakpoint

You were close on this one.

1. Open the Chrome Dev Tools (F12), and go to the Sources tab.
2. Drill down to Mouse -> Click
   
   (click to zoom)

2. Click the button!

Chrome Dev Tools will pause script execution, and present you with this beautiful entanglement of minified code:

(click to zoom)

3. Find the glorious code!

Now, the trick here is to not get carried away pressing the key, and keep an eye out on the screen.

1. Press the F11 key (Step In) until desired source code appears
2. Source code finally reached
   • In the jsFiddle sample provided above, I had to press F11 108 times before reaching the desired event handler/function
   • Your mileage may vary, depending on the version of jQuery (or framework library) used to bind the events
   • With enough dedication and time, you can find any event handler/function

4. Explanation

I don't have the exact answer, or explanation as to why jQuery goes through the many layers of abstractions it does - all I can suggest is that it is because of the job it does to abstract away its usage from the browser executing the code.

Here is a jsFiddle with a debug version of jQuery (i.e., not minified). When you look at the code on the first (non-minified) breakpoint, you can see that the code is handling many things:

    // ...snip...

    if ( !(eventHandle = elemData.handle) ) {
        eventHandle = elemData.handle = function( e ) {
            // Discard the second event of a jQuery.event.trigger() and
            // when an event is called after a page has unloaded
            return typeof jQuery !== strundefined && jQuery.event.triggered !== e.type ?
                jQuery.event.dispatch.apply( elem, arguments ) : undefined;
        };
    }

    // ...snip...

The reason I think you missed it on your attempt when the "execution pauses and I jump line by line", is because you may have used the "Step Over" function, instead of Step In. Here is a StackOverflow answer explaining the differences.

Finally, the reason why your function is not directly bound to the click event handler is because jQuery returns a function that gets bound. jQuery's function in turn goes through some abstraction layers and checks, and somewhere in there, it executes your function.

Try the following code:

For PHP 5.4.0 and above:

$filename = basename(parse_url('http://learner.com/learningphp.php?lid=1348')['path']);

For PHP Version < 5.4.0

$parsed = parse_url('http://learner.com/learningphp.php?lid=1348');
$filename = basename($parsed['path']);

String literals

Escaping single quotes ' by doubling them up -> '' is the standard way and works of course:

'user's log'     -- incorrect syntax (unbalanced quote)
'user''s log'

In old versions or if you still run with standard_conforming_strings = off or, generally, if you prepend your string with E to declare Posix escape string syntax, you can also escape with the backslash \:

E'user\'s log'

Backslash itself is escaped with another backslash. But that's generally not preferable.
If you have to deal with many single quotes or multiple layers of escaping, you can avoid quoting hell in PostgreSQL with dollar-quoted strings:

'escape '' with '''''
$$escape ' with ''$$

To further avoid confusion among dollar-quotes, add a unique token to each pair:

$token$escape ' with ''$token$

Which can be nested any number of levels:

$token2$Inner string: $token1$escape ' with ''$token1$ is nested$token2$

Pay attention if the $ character should have special meaning in your client software. You may have to escape it in addition. This is not the case with standard PostgreSQL clients like psql or pgAdmin.

That is all very useful for writing plpgsql functions or ad-hoc SQL commands. It cannot alleviate the need to use prepared statements or some other method to safeguard against SQL injection in your application when user input is possible, though. @Craig's answer has more on that. More details:

• SQL injection in Postgres functions vs prepared queries

Values inside Postgres

When dealing with values inside the database, there are a couple of useful functions to quote strings properly:

• quote_literal() or quote_nullable() - the latter outputs the string NULL for null input. (There is also quote_ident() to double-quote strings where needed to get valid SQL identifiers.)
• format() with the format specifier %L is equivalent to quote_nullable().
  Like: format('%L', string_var)
• concat() or concat_ws() are typically no good for this purpose as those do not escape nested single quotes and backslashes.

This is the one. The session will last for 1440 seconds (24 minutes).

Use insert:

In [1]: ls = [1,2,3]

In [2]: ls.insert(0, "new")

In [3]: ls
Out[3]: ['new', 1, 2, 3]

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

Using variable notation, you can do it without a temporary file:

${C:\file.txt} = ${C:\file.txt} | select -skip 1

function Remove-Topline ( [string[]]$path, [int]$skip=1 ) {
  if ( -not (Test-Path $path -PathType Leaf) ) {
    throw "invalid filename"
  }

  ls $path |
    % { iex "`${$($_.fullname)} = `${$($_.fullname)} | select -skip $skip" }
}

Thanks to @cssko for providing the correct answer, but if you tried it yourself you will realise it does not work. A suggestion has been made by @Matei Radu, but was rejected by @cssko, so the code remains unrunnable (it will throw error 'Cannot read property bind of undefined'). Below is the working correct answer:

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.addActiveClass = this.addActiveClass.bind(this);
    this.state = {
      active: false,
    };
  }
  addActiveClass() {
    const currentState = this.state.active;
    this.setState({
      active: !currentState
    });
  };

  render() {
    return ( <
      div className = {
        this.state.active ? 'your_className' : null
      }
      onClick = {
        this.addActiveClass
      } >
      <
      p > {
        this.props.text
      } < /p> < /
      div >
    )
  }
}

class Test extends React.Component {
  render() {
    return ( <
      div >
      <
      MyComponent text = {
        'Clicking this will toggle the opacity through css class'
      }
      /> < /
      div >
    );
  }
}

on MacOS Mojave, mysql_config is found at /usr/local/bin/ rather than /usr/local/mysql/bin as pointed above, so no need to add anything to path.

To sum with decimal use this:

In the javascript change parseInt with parseFloat and add this line tot.toFixed(2); for this result:

    function findTotal(){
    var arr = document.getElementsByName('qty');
    var tot=0;
    for(var i=0;i<arr.length;i++){
        if(parseFloat(arr[i].value))
            tot += parseFloat(arr[i].value);
    }
    document.getElementById('total').value = tot;
    tot.toFixed(2);
}

Use step=".01" min="0" type="number" in the input filed

Qty1 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty1"/><br>
Qty2 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty2"/><br>
Qty3 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty3"/><br>
Qty4 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty4"/><br>
Qty5 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty5"/><br>
Qty6 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty6"/><br>
Qty7 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty7"/><br>
Qty8 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty8"/><br>
<br><br>
Total : <input type="number" step=".01" min="0" name="total" id="total"/>

Uri to String

Uri uri;
String stringUri;
stringUri = uri.toString();

String to Uri

Uri uri;
String stringUri;
uri = Uri.parse(stringUri);

The WHERE clause is misplaced, it has to follow the table references and JOIN operations.

Something like this:

 FROM tartikel p1 
 JOIN tartikelpict p2 
   ON p1.kArtikel = p2.kArtikel 
  AND p2.nNr = 1
WHERE p1.dErstellt >= DATE(NOW()) - INTERVAL 7 DAY
ORDER BY p1.kArtikel DESC

EDIT (three plus years later)

The above essentially answers the question "I tried to add a WHERE clause to my query and now the query is returning an error, how do I fix it?"

As to a question about writing a condition that checks a date range of "last 7 days"...

That really depends on interpreting the specification, what the datatype of the column in the table is (DATE or DATETIME) and what data is available... what should be returned.

To summarize: the general approach is to identify a "start" for the date/datetime range, and "end" of that range, and reference those in a query. Let's consider something easier... all rows for "yesterday".

If our column is DATE type. Before we incorporate an expression into a query, we can test it in a simple SELECT

 SELECT DATE(NOW()) + INTERVAL -1 DAY 

and verify the result returned is what we expect. Then we can use that same expression in a WHERE clause, comparing it to a DATE column like this:

 WHERE datecol = DATE(NOW()) + INTERVAL -1 DAY

For a DATETIME or TIMESTAMP column, we can use >= and < inequality comparisons to specify a range

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -1 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

For "last 7 days" we need to know if that mean from this point right now, back 7 days ... e.g. the last 7*24 hours , including the time component in the comparison, ...

 WHERE datetimecol >= NOW() + INTERVAL -7 DAY
   AND datetimecol <  NOW() + INTERVAL  0 DAY

the last seven complete days, not including today

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -7 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

or past six complete days plus so far today ...

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -6 DAY
   AND datetimecol <  NOW()       + INTERVAL  0 DAY

I recommend testing the expressions on the right side in a SELECT statement, we can use a user-defined variable in place of NOW() for testing, not being tied to what NOW() returns so we can test borders, across week/month/year boundaries, and so on.

SET @clock = '2017-11-17 11:47:47' ;

SELECT DATE(@clock)
     , DATE(@clock) + INTERVAL -7 DAY 
     , @clock + INTERVAL -6 DAY 

Once we have expressions that return values that work for "start" and "end" for our particular use case, what we mean by "last 7 days", we can use those expressions in range comparisons in the WHERE clause.

(Some developers prefer to use the DATE_ADD and DATE_SUB functions in place of the + INTERVAL val DAY/HOUR/MINUTE/MONTH/YEAR syntax.

And MySQL provides some convenient functions for working with DATE, DATETIME and TIMESTAMP datatypes... DATE, LAST_DAY,

Some developers prefer to calculate the start and end in other code, and supply string literals in the SQL query, such that the query submitted to the database is

  WHERE datetimecol >= '2017-11-10 00:00'
    AND datetimecol <  '2017-11-17 00:00'

And that approach works too. (My preference would be to explicitly cast those string literals into DATETIME, either with CAST, CONVERT or just the + INTERVAL trick...

  WHERE datetimecol >= '2017-11-10 00:00' + INTERVAL 0 SECOND
    AND datetimecol <  '2017-11-17 00:00' + INTERVAL 0 SECOND

The above all assumes we are storing "dates" in appropriate DATE, DATETIME and/or TIMESTAMP datatypes, and not storing them as strings in variety of formats e.g. 'dd/mm/yyyy', m/d/yyyy, julian dates, or in sporadically non-canonical formats, or as a number of seconds since the beginning of the epoch, this answer would need to be much longer.

I would choose Sequelize because of it's excellent documentation. It's just a honest opinion (I never really used MySQL with Node that much).

Real answer can be found in specification, json is unordered. However as a human reader I ordered my elements in order of importance. Not only is it a more logic way, it happened to be easier to read. Maybe the author of the specification never had to read JSON, I do.. So, Here comes a fix:

/**
 * I got really tired of JSON rearranging added properties.
 * Specification states:
 * "An object is an unordered set of name/value pairs"
 * StackOverflow states:
 * As a consequence, JSON libraries are free to rearrange the order of the elements as they see fit.
 * I state:
 * My implementation will freely arrange added properties, IN SEQUENCE ORDER!
 * Why did I do it? Cause of readability of created JSON document!

I'm guessing

x= data[:,0]
y= data[:,1]

There is a way to accomplish this. The magic is to create a combined jacoco.exec file. And with maven 3.3.1 there is an easy way to get this. Here my profile:

If you add this profile to your parent pom and call mvn clean install sonar:sonar -DrunSonar you get the complete coverage.

The magic here is maven.multiModuleProjectDirectory. This folder is always the folder where you started your maven build.

To prevent this isue I changed all values in log4j.properties file with directory ${kafka.logs.dir} to my own directory. For example D:/temp/...

replace all the \ with \\.

it's trying to escape the next character in this case the U so to insert a \ you need to insert an escaped \ which is \\

Differences between PUT and PATCH The main difference between PUT and PATCH requests is witnessed in the way the server processes the enclosed entity to update the resource identified by the Request-URI. When making a PUT request, the enclosed entity is viewed as the modified version of the resource saved on the original server, and the client is requesting to replace it. However, with PATCH, the enclosed entity boasts a set of instructions that describe how a resource stored on the original server should be partially modified to create a new version.

The second difference is when it comes to idempotency. HTTP PUT is said to be idempotent since it always yields the same results every after making several requests. On the other hand, HTTP PATCH is basically said to be non-idempotent. However, it can be made to be idempotent based on where it is implemented.

Personally I would use the Maven surefire JUnit runner to do that.

I to had a similar doubt what I got to know was getActivity() returns the Activity to which the fragment is associated.

The getActivity() method is used generally in static fragment as the associated activity will not be static and non static member cannot be used in static member.

The dot operator . does not need to be escaped inside of a character class [].

npm config delete proxy

It depends on the time format of the user's operating system when the web browser was launched.

So:

• If your computer's system prefs are set to use a 24-hour clock, the browser will render the <input type="time"> element as --:-- (time range: 00:00–23:59).
• If you change your computer's syst prefs to use 12-hour, the output won't change until you quit and relaunch the browser. Then it will change to --:-- -- (time range: 12:00 AM – 11:59 PM).

And (as of this writing), browser support is only about 75% (caniuse). Yay: Edge, Chrome, Opera, Android. Boo: IE, Firefox, Safari).

Pax is correct about the reasons for TIME_WAIT, and why you should be careful about lowering the default setting.

A better solution is to vary the port numbers used for the originating end of your sockets. Once you do this, you won't really care about time wait for individual sockets.

For listening sockets, you can use SO_REUSEADDR to allow the listening socket to bind despite the TIME_WAIT sockets sitting around.

On centos 7, I just do

sudo yum install java-sdk

I assume you have most common repo already. Centos just finds the correct SDK with the -devel sufix.

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

Try this awk

awk -F, '{$0=$3}1' file
column3

• , Divide fields by ,
• $0=$3 Set the line to only field 3
• 1 Print all out. (explained here)

This could also be used:

awk -F, '{print $3}' file

In my case, I had accidentally named a folder 'samples '. I couldn't see the space when I did 'ls -la'.

Eventually I realized this when I tried tabbing to autocomplete and saw 'samples\ /'.

To fix this I ran

mv samples\  samples

In Google chrome, Inspect element tool you can view any Javascript function definition.

1. Click on the Sources tab. Then select the index page. Search for the function.

2. Select the function then Right-click on the function and select "Evaluate selected text in console."

Part of the answer to 'handle' the 'Sequence has no elements' Exception in VB is to test for empty

If Not (myMap Is Nothing) Then
' execute code
End if

Where MyMap is the sequence queried returning empty/null. FYI

Yes, it's done in the Collections class. Note that you will need to convert your primitive char array to a Character[] manually.

A short demo:

import java.util.*;

public class Main {

    public static Character[] convert(char[] chars) {
        Character[] copy = new Character[chars.length];
        for(int i = 0; i < copy.length; i++) {
            copy[i] = Character.valueOf(chars[i]);
        }
        return copy;
    }

    public static void main(String[] args) {
        char[] a = {'3', '5', '1', '4', '2'};
        Character[] b = convert(a);
        System.out.println(Collections.max(Arrays.asList(b)));
    }
}

Ok, I think for a novice things might be a bit confusing. I think the correct answer is a mix of all the above, at least in Swift4.

Either create an extension or use the ViewController in which you'd like to use this but make sure to implement UITextFieldDelegate. For reusability's sake I found it easier to use an extension:

extension UIViewController : UITextFieldDelegate {
    ...
}

but the alternative works as well:

class MyViewController: UIViewController {
    ...
}

Add the method textFieldShouldReturn (depending on your previous option, either in the extension or in your ViewController)

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    return textField.endEditing(false)
}

In your viewDidLoad method, set the textfield's delegate to self

@IBOutlet weak var myTextField: UITextField!
...

override func viewDidLoad() {
    ..
    myTextField.delegte = self;
    ..
}

That should be all. Now, when you press return the textFieldShouldReturn should be called.

It looks like you're using python 3.x. In python3, filter, map, zip, etc return an object which is iterable, but not a list. In other words,

filter(func,data) #python 2.x

is equivalent to:

list(filter(func,data)) #python 3.x

I think it was changed because you (often) want to do the filtering in a lazy sense -- You don't need to consume all of the memory to create a list up front, as long as the iterator returns the same thing a list would during iteration.

If you're familiar with list comprehensions and generator expressions, the above filter is now (almost) equivalent to the following in python3.x:

( x for x in data if func(x) ) 

As opposed to:

[ x for x in data if func(x) ]

in python 2.x

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

For folks that have programmed in nodeJs before, particularly using expressJS. I think of .ashx as a middleware that calls the next function. While .aspx will be the controller that actually responds to the request either around res.redirect, res.send or whatever.

There is now another way to install the gcc toolchain on OS X through the osx-gcc-installer this includes:

• GCC
• LLVM
• Clang
• Developer CLI Tools (purge, make, etc)
• DevSDK (headers, etc)

The download is 282MB vs 3GB for Xcode.

Try this one:

var comment = document.querySelector("button");
function showComment() {
  var place = document.querySelector('#textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
}
comment.addEventListener('click', showComment, false);

Use querySelector instead of className

An alternative would be to place your regexp in non-capturing parentheses. Then make that expression optional using the ? qualifier, which will look for 0 (i.e. empty string) or 1 instances of the non-captured group.

For example:

/(?: some regexp )?/

In your case the regular expression would look something like this:

/^(?:[\w\.\-]+@([\w\-]+\.)+[a-zA-Z]+)?$/

No | "or" operator necessary!

Here is the Mozilla documentation for JavaScript Regular Expression syntax.

Try these to clarify the issue of right alignment in float point printing

printf(" 4|%4.1lf\n", 8.9);
printf("04|%04.1lf\n", 8.9);

the output is

 4| 8.9
04|08.9

I had a similar problem. And i had to make it install the same way, we do from pypi.

I did the following things:

1. Make a directory to store all the packages in the machine that have internet access.

   mkdir -p /path/to/packages/
   

2. Download all the packages to the path

Edit: You can also try:

python3 -m pip wheel --no-cache-dir -r requirements.txt -w /path/to/packages

pip download -r requirements.txt -d /path/to/packages

Eg:- ls /root/wheelhouse/  # **/root/wheelhouse** is my **/path/to/packages/**

3. Tar the packages directory and copy it to the Machine that doesn't have internet access. Then do,

   cd /path/to/packages/
   tar -cvzf packages.tar.gz .  # not the . (dot) at the end
   

Copy the packages.tar.gz into the destination machine that doesn't have internet access.

4. In the machine that doesn't have internet access, do the following (Assuming you copied the tarred packages to /path/to/package/ in the current machine)

   cd /path/to/packages/
   tar -xvzf packages.tar.gz
   mkdir -p $HOME/.config/pip/
   vi $HOME/.config/pip/pip.conf
   

and paste the following content inside and save it.

[global]
timeout = 10
find-links = file:///path/to/package/
no-cache-dir = true
no-index = true

5. Finally, i suggest you use, some form of virtualenv for installing the packages.

   virtualenv -p python2 venv # use python3, if you are on python3
   source ./venv/bin/activate
   pip install <package>
   

You should be able to download all the modules that are in the directory /path/to/package/.

Note: I only did this, because i couldn't add options or change the way we install the modules. Otherwise i'd have done

pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt

You cannot style things like radio buttons, checkboxes, scrollsbars (etc.) at all. These are native to the OS and the browser and not something you can manipulate.

You can simulate this, however by hiding the radio buttons and only showing an image instead as in.

<input type="radio" style="display: none;" id="sad" /><label for="sad"><img class="sad_image" /></label>

I found one way to access the shared folder without giving the username and password.

We need to change the share folder protect settings in the machine where the folder has been shared.

Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.

By doing the above settings we can access the shared folder without any username/password.

Implementation with Guzzle library:

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;

$httpClient = new Client();

$response = $httpClient->post(
    'https://postman-echo.com/post',
    [
        RequestOptions::BODY => 'POST raw request content',
        RequestOptions::HEADERS => [
            'Content-Type' => 'application/x-www-form-urlencoded',
        ],
    ]
);

echo(
    $response->getBody()->getContents()
);

PHP CURL extension:

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [
    CURLOPT_URL => 'https://postman-echo.com/post',
    CURLOPT_RETURNTRANSFER => true,

    /**
     * Specify POST method
     */
    CURLOPT_POST => true,

    /**
     * Specify request content
     */
    CURLOPT_POSTFIELDS => 'POST raw request content',
]);

$response = curl_exec($curlHandler);

curl_close($curlHandler);

echo($response);

No matter how many times you import a module, you'll get the same copy of the module from sys.modules - which was loaded at first import mymodule

I am answering this late, as each of the above/previous answer has a bit of the answer, so I am attempting to sum it all up in a single answer.

Using built-in function:

For Python 2.x - Use the built-in reload(mymodule) function.

For Python 3.x - Use the imp.reload(mymodule).

For Python 3.4 - In Python 3.4 imp has been deprecated in favor of importlib i.e. importlib.reload(mymodule)

Few caveats:

• It is generally not very useful to reload built-in or dynamically loaded modules. Reloading sys, __main__, builtins and other key modules is not recommended.
• In many cases extension modules are not designed to be initialized more than once, and may fail in arbitrary ways when reloaded. If a module imports objects from another module using from ... import ..., calling reload() for the other module does not redefine the objects imported from it — one way around this is to re-execute the from statement, another is to use import and qualified names (module.name) instead.
• If a module instantiates instances of a class, reloading the module that defines the class does not affect the method definitions of the instances — they continue to use the old class definition. The same is true for derived classes.

External packages:

reimport - Reimport currently supports Python 2.4 through 2.7.

xreload- This works by executing the module in a scratch namespace, and then patching classes, methods and functions in place. This avoids the need to patch instances. New objects are copied into the target namespace.

livecoding - Code reloading allows a running application to change its behaviour in response to changes in the Python scripts it uses. When the library detects a Python script has been modified, it reloads that script and replaces the objects it had previously made available for use with newly reloaded versions. As a tool, it allows a programmer to avoid interruption to their workflow and a corresponding loss of focus. It enables them to remain in a state of flow. Where previously they might have needed to restart the application in order to put changed code into effect, those changes can be applied immediately.

You can use Borderless style in AppCompatButton like below. and use android:background with it.

style="@style/Widget.AppCompat.Button.Borderless.Colored"

Button code

<androidx.appcompat.widget.AppCompatButton
        android:id="@+id/button_visa_next"
        android:background="@color/colorPrimary"
        style="@style/Widget.AppCompat.Button.Borderless.Colored"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/spacing_normal"
        android:text="@string/next"
        android:textColor="@color/white"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

Output:

Like the other answer says, put the & after the *.

This brings up an interesting point that can be confusing sometimes: types should be read from right to left. For example, this is (starting from the rightmost *) a pointer to a constant pointer to an int.

int * const *x;

What you wrote would therefore be a pointer to a reference, which is not possible.

You can always use System.Resources.ResourceManager which returns the cached ResourceManager used by this class. Since chan1 and chan2 represent two different images, you may use System.Resources.ResourceManager.GetObject(string name) which returns an object matching your input with the project resources

Example

object O = Resources.ResourceManager.GetObject("chan1"); //Return an object from the image chan1.png in the project
channelPic.Image = (Image)O; //Set the Image property of channelPic to the returned object as Image

Notice: Resources.ResourceManager.GetObject(string name) may return null if the string specified was not found in the project resources.

Thanks,
I hope you find this helpful :)

Array.prototype.map() index:

One can access the index Array.prototype.map() via the second argument of the callback function. Here is an example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
_x000D_
const map = array.map((x, index) => {_x000D_
  console.log(index);_x000D_
  return x + index;_x000D_
});_x000D_
_x000D_
console.log(map);

Other arguments of Array.prototype.map():

• The third argument of the callback function exposes the array on which map was called upon
• The second argument of Array.map() is a object which will be the this value for the callback function. Keep in mind that you have to use the regular function keyword in order to declare the callback since an arrow function doesn't have its own binding to the this keyword.

For example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
const thisObj = {prop1: 1}_x000D_
_x000D_
_x000D_
const map = array.map( function (x, index, array) {_x000D_
  console.log(array);_x000D_
  console.log(this)_x000D_
}, thisObj);

Run

npm i @types/jquery
npm install -D @types/bootstrap

in the project to add the jquery types in your Angular Project. After that include

import * as $ from "jquery";
import * as bootstrap from "bootstrap";

in your app.module.ts

Add

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

in your index.html just before the body closing tag.

And if you are running Angular 2-7 include "jquery" in the types field of tsconfig.app.json file.

This will remove all error of 'modal' and '$' in your Angular project.

I've written this, but have to check the existing methods mentioned to see if they are better.

It generally it helps to avoid SQL injection, for example consider the following code:

<?php
// Query database to check if there are any matching users
$query = "SELECT * FROM users WHERE user='{$_POST['username']}' AND password='{$_POST['password']}'";
mysql_query($query);

// We didn't check $_POST['password'], it could be anything the user wanted! For example:
$_POST['username'] = 'aidan';
$_POST['password'] = "' OR ''='";

// This means the query sent to MySQL would be:
echo $query;
?>

and a hacker can send a query like:

SELECT * FROM users WHERE user='aidan' AND password='' OR ''=''

This would allow anyone to log in without a valid password.

Your virtualhost filename should be mysite.com.conf and should contain this info

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is)

        double toLat = 50.45, toLon = 30.523333;
        String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
        InputStream is = getConnection(url);
        mRoad = RoadProvider.getRoute(is);
        map = new MapControl();
        add(new LabelField(mRoad.mName));
        add(new LabelField(mRoad.mDescription));
        add(map);
    }
    protected void onUiEngineAttached(boolean attached) {
        super.onUiEngineAttached(attached);
        if (attached) {
            map.drawPath(mRoad);
        }
    }
    private InputStream getConnection(String url) {
        HttpConnection urlConnection = null;
        InputStream is = null;
        try {
            urlConnection = (HttpConnection) Connector.open(url);
            urlConnection.setRequestMethod("GET");
            is = urlConnection.openInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return is;

Whenever possible, you should avoid parsing the output of ls (see Greg's wiki on the subject). Basically, the output of ls will be ambiguous if there are funny characters in any of the filenames. It's also usually a waste of time. In this case, when you execute ls -d */, what happens is that the shell expands */ to a list of subdirectories (which is already exactly what you want), passes that list as arguments to ls -d, which looks at each one, says "yep, that's a directory all right" and prints it (in an inconsistent and sometimes ambiguous format). The ls command isn't doing anything useful!

Well, ok, it is doing one thing that's useful: if there are no subdirectories, */ will get left as is, ls will look for a subdirectory named "*", not find it, print an error message that it doesn't exist (to stderr), and not print the "*/" (to stdout).

The cleaner way to make an array of subdirectory names is to use the glob (*/) without passing it to ls. But in order to avoid putting "*/" in the array if there are no actual subdirectories, you should set nullglob first (again, see Greg's wiki):

shopt -s nullglob
array=(*/)
shopt -u nullglob # Turn off nullglob to make sure it doesn't interfere with anything later
echo "${array[@]}"  # Note double-quotes to avoid extra parsing of funny characters in filenames

If you want to print an error message if there are no subdirectories, you're better off doing it yourself:

if (( ${#array[@]} == 0 )); then
    echo "No subdirectories found" >&2
fi

Using the Maven artifact org.json:json I got the following code, which I think is quite short. Not as short as possible, but still usable.

public class JsonReader {

  private static String readAll(Reader rd) throws IOException {
    StringBuilder sb = new StringBuilder();
    int cp;
    while ((cp = rd.read()) != -1) {
      sb.append((char) cp);
    }
    return sb.toString();
  }

  public static JSONObject readJsonFromUrl(String url) throws IOException, JSONException {
    InputStream is = new URL(url).openStream();
    try {
      BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
      String jsonText = readAll(rd);
      JSONObject json = new JSONObject(jsonText);
      return json;
    } finally {
      is.close();
    }
  }

  public static void main(String[] args) throws IOException, JSONException {
    JSONObject json = readJsonFromUrl("https://graph.facebook.com/19292868552");
    System.out.println(json.toString());
    System.out.println(json.get("id"));

I had the same problem with a Samsung galaxy note 2. It was recognized on one pc but not on another one (both running windows 7 64b). After hours of struggling, I installed Kies (from the Samsung website) on the pc where Android Studio was unable to detect the smartphone (Kies was installed on the other one).

Like magic, Android Studio detected the phone !!! I noticed that the Kies installer installed some driver for the phone.

Consequently, for those meeting the same detection problem, I would strongly advise to first install Kies.

You must update the Windows PowerShell to minimum of version 4.0 for the script below to work.

[array]$SiteLinks = "http://mypage.global/Chemical/test.html"
"http://maypage2:9080/portal/site/hotpot/test.json"


foreach($url in $SiteLinks) {

   try {
      Write-host "Verifying $url" -ForegroundColor Yellow
      $checkConnection = Invoke-WebRequest -Uri $url
      if ($checkConnection.StatusCode -eq 200) {
         Write-Host "Connection Verified!" -ForegroundColor Green
      }

   } 
   catch [System.Net.WebException] {
      $exceptionMessage = $Error[0].Exception
      if ($exceptionMessage -match "503") {
         Write-Host "Server Unavaiable" -ForegroundColor Red
      }
      elseif ($exceptionMessage -match "404") {
         Write-Host "Page Not found" -ForegroundColor Red
      }


   }
}

An array "decays" into a pointer to its first element, so scanf("%s", string) is equivalent to scanf("%s", &string[0]). On the other hand, scanf("%s", &string) passes a pointer-to-char[256], but it points to the same place.

Then scanf, when processing the tail of its argument list, will try to pull out a char *. That's the Right Thing when you've passed in string or &string[0], but when you've passed in &string you're depending on something that the language standard doesn't guarantee, namely that the pointers &string and &string[0] -- pointers to objects of different types and sizes that start at the same place -- are represented the same way.

I don't believe I've ever encountered a system on which that doesn't work, and in practice you're probably safe. None the less, it's wrong, and it could fail on some platforms. (Hypothetical example: a "debugging" implementation that includes type information with every pointer. I think the C implementation on the Symbolics "Lisp Machines" did something like this.)

You might need to set GEM_HOME for the cleanup to work. You can check what paths exist for gemfiles by running:

gem env

Take note of the GEM PATHS section.

In my case, for example, with gems installed in my user home:

export GEM_HOME="~/.gem/ruby/2.4.0"
gem cleanup

```javascript
{ "some": "json" }
```

I tried using json but didn't like the way it looked. javascript looks a bit more pleasing to my eye.

If you're using Joda-Time (and there are lots of good reasons to - a simple, intuitive API and thread-safety) then you can do this trivially:

(new LocalDate()).plusDays(5);

to give 5 days from today, for example.

EDIT: My current advice would be to now use the Java 8 date/time api

This was the best solution I found after more time than I care to admit. Basically, add target="_self" to each link that you need to insure a page reload.

Let suppose if you want to make the bar button in a separate file(for modular approach) and want to give selector back to your viewcontroller, you can do like this :-

your Utility File

class GeneralUtility {

    class func customeNavigationBar(viewController: UIViewController,title:String){
        let add = UIBarButtonItem(title: "Play", style: .plain, target: viewController, action: #selector(SuperViewController.buttonClicked(sender:)));  
      viewController.navigationController?.navigationBar.topItem?.rightBarButtonItems = [add];
    }
}

Then make a SuperviewController class and define the same function on it.

class SuperViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
            // Do any additional setup after loading the view.
    }
    @objc func buttonClicked(sender: UIBarButtonItem) {

    }
}

and In our base viewController(which inherit your SuperviewController class) override the same function

import UIKit

class HomeViewController: SuperViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func viewWillAppear(_ animated: Bool) {
        GeneralUtility.customeNavigationBar(viewController: self,title:"Event");
    }

    @objc override func buttonClicked(sender: UIBarButtonItem) {
      print("button clicked")    
    } 
}

Now just inherit the SuperViewController in whichever class you want this barbutton.

Thanks for the read

you pretty much answered your own question - hashset doesn't allow duplicate values. it would be trivial to build a hashset using a backing hashmap (and just a check to see if the value already exists). i guess the various java implementations either do that, or implement some custom code to do it more efficiently.

For ex .. add class:

btn-lg - LARGE

btn-sm - SMALL

btn-xs - Very small

<button type=button class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default">
<span class="glyphicon glyphicon-star" aria-hidden=true></span>Star
</button>

 <button type=button class="btn btn-default btn-sm">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default btn-xs">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>

Using the selectedOptions property (HTML5) you can get the selected option(s)

document.getElementbyId("id").selectedOptions; 

With JQuery can be achieved by doing this

$("#id")[0].selectedOptions; 

or

$("#id").prop("selectedOptions");

The property contains an HTMLCollection array similitar to this one selected option

[<option value=?"1">?ABC</option>]

or multiple selections

[<option value=?"1">?ABC</option>, <option value=?"2">?DEF</option> ...]

First, you'll need to tell git about yourself. Get your username and token together from your settings page.

Then run:

git config --global github.user YOUR_USERNAME
git config --global github.token YOURTOKEN

You will need to generate a new key if you don't have a back-up of your key.

Then you should be able to run:

git clone [email protected]:YOUR_USERNAME/YOUR_PROJECT.git

You need to say math.sqrt when you use it. Or, do from math import sqrt.

Hmm, I just read your question more thoroughly.... How are you importing math? I just tried import math and then math.sqrt which worked perfectly. Are you doing something like import math as m? If so, then you have to prefix the function with m (or whatever name you used after as).

pow is working because there are two versions: an always available version in __builtin__, and another version in math.

Note: The original question was answered already, but I would just like to expand on it with some extras that are relevant to the topic.

Your AIX installation would first be put into volume groups. This is done upon installation.

It will first create rootvg (as in root volume group). This is kinda like your actual hard drive mapped.

This would be equivalent to Disc Management in Windows. AIX wont use up all of that space for its file systems like we tend to do it in consumer Windows machines. Instead there will be a good bit of unallocated space.

To check how much space your rootvg would have you use the following command.

lsvg rootvg

That would stand for list volume group rootvg. This will give you information like the size of physical partitions (PP), Total PPs assigned to the volume group, Free PPs in the volume group, etc. Regardless, the output should be fairly comprehensive.

Next thing you may be interested in, is the file systems on the volume group. Each file system would have certain amount of space given within the volume group it belongs to.

To check what file systems you got on your volume group you use the following command.

lsvgfs rootvg

As in list volume group file systems for rootvg.

You can check how much space each file system has using the following command.

df

I personally like to refine it with flags like -m and -g (in megabytes and gigabytes respectively)

If you have free space available in your volume group, you can assign it to your file systems using the following command.

chfs -a size=+1G /home

As in change file system attribute size by adding 1 G where file system is /home. use man chfs for more instructions. This is a powerful tool. This example is for adjusting size, however you can do more with this command than that.

Sources: http://www.ibm.com/developerworks/aix/library/au-rootvg/ + My own experience working with AIX.

You can use the eclipse plugin as suggested by Oscar earlier. Or if you are a command line person, you can use Apache Axis WSDL2Java tool from command prompt. You can find more details here http://axis.apache.org/axis/java/reference.html#WSDL2JavaReference

There are few ways to specify default server.

First way - Specify default server first in list, if you keep your server configurations in one config file, like Dayo showed above.

Second way (better) More flexible - provide default_server parameter for listen instruction, for example:

server {
    listen  *:80 default_server;
    root /www/project/public/;
}

More information here: Nginx doc / Listen

This way more useful when you keep server configurations in separate files and do not want to name those files alphabetically.

I think the previous answers missed the most important (non-trivial) aspect of the OP's question, i.e., how to perform the search/replace in a "time saving" manner, meaning once, not three times, and "maintain case" originally present.

On the pane, check "[X] Preserve Case" before clicking the Replace All button

This performs a case-aware "smart" replacement in one pass:

apple -> orange
Apple -> Orange
APPLE -> ORANGE

Also, for peace of mind, don't forget to check the code into the VCS before performing sweeping project-wide replacements.

With jQuery:

$("#fileRequest").click(function() {
    // // hope the server sets Content-Disposition: attachment!
    window.location = 'file.doc';
});

The javadoc for setParameter(String, Object) is explicit, saying that the Object value must be non-null. It's a shame that it doesn't throw an exception if a null is passed in, though.

An alternative is setParameter(String, Object, Type), which does allow null values, although I'm not sure what Type parameter would be most appropriate here.

I had the same issue and reason was penny. Wrong profile and certificate was selected in build settings. I only had did this before few days. So, you do not need to enable "automatic" inside xcode. Check profiles inside your build settings before doing it.

I had a similar problem, when I wanted to create a command, \dx, to abbreviate \;\mathrm{d}x (i.e. put an extra space before the differential of the integral and have the "d" upright as well). But then I also wanted to make it flexible enough to include the variable of integration as an optional argument. I put the following code in the preamble.

\usepackage{ifthen}

\newcommand{\dx}[1][]{%
   \ifthenelse{ \equal{#1}{} }
      {\ensuremath{\;\mathrm{d}x}}
      {\ensuremath{\;\mathrm{d}#1}}
}

Then

\begin{document}
   $$\int x\dx$$
   $$\int t\dx[t]$$
\end{document}

gives \dx with optional argument

You can pass $state to your controller and then when the page loads and calls the getter in the controller you call $state.go('index') or whatever partial you want to load. Done.

Looking at your output maybe the following query can work, give it a try:

SELECT * FROM tablename
WHERE id IN
(SELECT MIN(id) FROM tablename GROUP BY EmailAddress)

This will select only one row for each distinct email address, the row with the minimum id which is what your result seems to portray

'Convert Indentation to Spaces'

OR

'Convert Indentation to Tabs'

Your code will work in either case.

Additionally, if you want Sublime text to do it automatically for you for every code you can update the Preference settings as below:-

Sublime Text menu > Preferences > Settings - Syntax Specific :

Python.sublime-settings

{
    "tab_size": 4,
    "translate_tabs_to_spaces": true
}

The following replaces variables of the form <<VAR>>, with values looked up from a Map. You can test it online here

For example, with the following input string

BMI=(<<Weight>>/(<<Height>>*<<Height>>)) * 70
Hi there <<Weight>> was here

and the following variable values

Weight, 42
Height, HEIGHT 51

outputs the following

BMI=(42/(HEIGHT 51*HEIGHT 51)) * 70

Hi there 42 was here

Here's the code

  static Pattern pattern = Pattern.compile("<<([a-z][a-z0-9]*)>>", Pattern.CASE_INSENSITIVE);

  public static String replaceVarsWithValues(String message, Map<String,String> varValues) {
    try {
      StringBuffer newStr = new StringBuffer(message);
      int lenDiff = 0;
      Matcher m = pattern.matcher(message);
      while (m.find()) {
        String fullText = m.group(0);
        String keyName = m.group(1);
        String newValue = varValues.get(keyName)+"";
        String replacementText = newValue;
        newStr = newStr.replace(m.start() - lenDiff, m.end() - lenDiff, replacementText);
        lenDiff += fullText.length() - replacementText.length();
      }
      return newStr.toString();
    } catch (Exception e) {
      return message;
    }
  }


  public static void main(String args[]) throws Exception {
      String testString = "BMI=(<<Weight>>/(<<Height>>*<<Height>>)) * 70\n\nHi there <<Weight>> was here";
      HashMap<String,String> values = new HashMap<>();
      values.put("Weight", "42");
      values.put("Height", "HEIGHT 51");
      System.out.println(replaceVarsWithValues(testString, values));
  }

and although not requested, you can use a similar approach to replace variables in a string with properties from your application.properties file, though this may already be being done:

private static Pattern patternMatchForProperties =
      Pattern.compile("[$][{]([.a-z0-9_]*)[}]", Pattern.CASE_INSENSITIVE);

protected String replaceVarsWithProperties(String message) {
    try {
      StringBuffer newStr = new StringBuffer(message);
      int lenDiff = 0;
      Matcher m = patternMatchForProperties.matcher(message);
      while (m.find()) {
        String fullText = m.group(0);
        String keyName = m.group(1);
        String newValue = System.getProperty(keyName);
        String replacementText = newValue;
        newStr = newStr.replace(m.start() - lenDiff, m.end() - lenDiff, replacementText);
        lenDiff += fullText.length() - replacementText.length();
      }
      return newStr.toString();
    } catch (Exception e) {
      return message;
    }
  }

If you're stuck with pre-5.10, then the solutions provided above will not fully replicate the say function. For example

sub say { print @_, "\n"; }

Will not work with invocations such as

say for @arr;

or

for (@arr) {
    say;
}

... because the above function does not act on the implicit global $_ like print and the real say function.

To more closely replicate the perl 5.10+ say you want this function

sub say {
    if (@_) { print @_, "\n"; }
    else { print $_, "\n"; }
}

Which now acts like this

my @arr = qw( alpha beta gamma );
say @arr;
# OUTPUT
# alphabetagamma
#
say for @arr;
# OUTPUT
# alpha
# beta
# gamma
#

The say builtin in perl6 behaves a little differently. Invoking it with say @arr or @arr.say will not just concatenate the array items, but instead prints them separated with the list separator. To replicate this in perl5 you would do this

sub say {
    if (@_) { print join($", @_) . "\n"; }
    else { print $_ . "\n"; }
}

$" is the global list separator variable, or if you're using English.pm then is is $LIST_SEPARATOR

It will now act more like perl6, like so

say @arr;
# OUTPUT
# alpha beta gamma
#

Do not we have an app which can stream the digital movie from iOS devices like iPhone or iPad to be played on a high definition LED or Plasma TV?

I know of an app air video server which can be used to display content played on computer or laptop on iOS device. But is there any app that can do the reverse & play the digital content from iphone to LED tv .

Easier method is window.location.href = "http://example.com/new_url";

But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database. You can do this easily following this code.

html form -

<form name="myForm" onsubmit="return validateForm()" method="POST" action="login.php" >         
    <input type="text" name="username" id="username" />
    <input type="password" name="password" id="password" />
    <input type="submit" name="submitBt"value="LogIn" />
</form>

javascript validation-

function validateForm(){
    var uname = document.forms["myForm"]["username"].value;
    var pass = document.forms["myForm"]["password"].value;

    if((!isEmpty(uname, "Log In")) && (!isEmpty(pass, "Password"))){

        return true;
    }else{
        return false;
    }
}

function isEmpty(elemValue, field){
    if((elemValue == "") || (elemValue == null)){
        alert("you can not have "+field+" field empty");
        return true;
    }else{
        return false;
    }
}

check if user in the database using php

<?php
    $con = mysqli_connect("localhost","root","1234","users");

    if(mysqli_connect_errno()){
        echo "Couldn't connect ".mysqli_connect_error();
    }else{
        //echo "connection successful <br />";
    }

    $uname_tb = $_POST['username'];
    $pass_tb = $_POST['password'];

    $query ="SELECT * FROM user";
    $result = mysqli_query($con,$query);

    while($row = mysqli_fetch_array($result)){
        if(($row['username'] == $uname_tb) && ($row['password'] == $pass_tb)){
            echo "Login Successful";
            header('Location: dashbord.php');
            exit();
        }else{
            echo "You are not in our database".mysqli_connect_error();
        }
    }
    mysqli_close($con);
?>

You must specify :

Response.AppendHeader("content-disposition", "inline; filename=file.pdf");
return new FileStreamResult(stream, "application/pdf")

For the file to be opened directly in the browser instead of being downloaded

Know it's an old post. But these issues still exist.

Here are some of my findings on the subject, grossly explained.

"Status" 0 means one of 3 things, as per the XMLHttpRequest spec:

• dns name resolution failed (that's for instance when network plug is pulled out)

• server did not answer (a.k.a. unreachable or unresponding)

• request was aborted because of a CORS issue (abortion is performed by the user-agent and follows a failing OPTIONS pre-flight).

If you want to go further, dive deep into the inners of XMLHttpRequest. I suggest reading the ready-state update sequence ([0,1,2,3,4] is the normal sequence, [0,1,4] corresponds to status 0, [0,1,2,4] means no content sent which may be an error or not). You may also want to attach listeners to the xhr (onreadystatechange, onabort, onerror, ontimeout) to figure out details.

From the spec (XHR Living spec):

const unsigned short UNSENT = 0;
const unsigned short OPENED = 1;
const unsigned short HEADERS_RECEIVED = 2;
const unsigned short LOADING = 3;
const unsigned short DONE = 4;

Let's revisit key phases of Mapreduce program.

The map phase is done by mappers. Mappers run on unsorted input key/values pairs. Each mapper emits zero, one, or multiple output key/value pairs for each input key/value pairs.

The combine phase is done by combiners. The combiner should combine key/value pairs with the same key. Each combiner may run zero, once, or multiple times.

The shuffle and sort phase is done by the framework. Data from all mappers are grouped by the key, split among reducers and sorted by the key. Each reducer obtains all values associated with the same key. The programmer may supply custom compare functions for sorting and a partitioner for data split.

The partitioner decides which reducer will get a particular key value pair.

The reducer obtains sorted key/[values list] pairs, sorted by the key. The value list contains all values with the same key produced by mappers. Each reducer emits zero, one or multiple output key/value pairs for each input key/value pair.

Have a look at this javacodegeeks article by Maria Jurcovicova and mssqltips article by Datta for a better understanding

Below is the image from safaribooksonline article

In this case, one of the easiest and best approach is to first cast it to list and then use where or select.

result = result.ToList().where(p => date >= p.DOB);

I was getting an error while using "import dns.resolver". I tried dnspython, py3dns but they failed. dns won't install. after much hit and try I installed pubdns module and it solved my problem.

Here is a drop-in class that sub-classes ObservableCollection and actually raises a Reset action when a property on a list item changes. It enforces all items to implement INotifyPropertyChanged.

The benefit here is that you can data bind to this class and all of your bindings will update with changes to your item properties.

public sealed class TrulyObservableCollection<T> : ObservableCollection<T>
    where T : INotifyPropertyChanged
{
    public TrulyObservableCollection()
    {
        CollectionChanged += FullObservableCollectionCollectionChanged;
    }

    public TrulyObservableCollection(IEnumerable<T> pItems) : this()
    {
        foreach (var item in pItems)
        {
            this.Add(item);
        }
    }

    private void FullObservableCollectionCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        if (e.NewItems != null)
        {
            foreach (Object item in e.NewItems)
            {
                ((INotifyPropertyChanged)item).PropertyChanged += ItemPropertyChanged;
            }
        }
        if (e.OldItems != null)
        {
            foreach (Object item in e.OldItems)
            {
                ((INotifyPropertyChanged)item).PropertyChanged -= ItemPropertyChanged;
            }
        }
    }

    private void ItemPropertyChanged(object sender, PropertyChangedEventArgs e)
    {            
        NotifyCollectionChangedEventArgs args = new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Replace, sender, sender, IndexOf((T)sender));
        OnCollectionChanged(args);
    }
}

I recently solved this problem with a good solution.

CSS:

.avoidBreak { 
    border: 2px solid;
    page-break-inside:avoid;
}

JS:

function Print(){
    $(".tableToPrint td, .tableToPrint th").each(function(){ $(this).css("width",  $(this).width() + "px")  });
    $(".tableToPrint tr").wrap("<div class='avoidBreak'></div>");
    window.print();
}

Works like a charm!

This has been really helpful. Here is my implementation for any given table:

def sql_replace(self, tableobject, dictargs):

    #missing check of table object is valid
    primarykeys = [key.name for key in inspect(tableobject).primary_key]

    filterargs = []
    for primkeys in primarykeys:
        if dictargs[primkeys] is not None:
            filterargs.append(getattr(db.RT_eqmtvsdata, primkeys) == dictargs[primkeys])
        else:
            return

    query = select([db.RT_eqmtvsdata]).where(and_(*filterargs))

    if self.r_ExecuteAndErrorChk2(query)[primarykeys[0]] is not None:
        # update
        filter = and_(*filterargs)
        query = tableobject.__table__.update().values(dictargs).where(filter)
        return self.w_ExecuteAndErrorChk2(query)

    else:
        query = tableobject.__table__.insert().values(dictargs)
        return self.w_ExecuteAndErrorChk2(query)

# example usage
inrow = {'eqmtvs_id': eqmtvsid, 'datetime': dtime, 'param_id': paramid}

self.sql_replace(tableobject=db.RT_eqmtvsdata, dictargs=inrow)

don't know why, but it works. Two configuration are the same, just change xxx to your name.

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "xxxEntityManager",
    transactionManagerRef = "xxxTransactionManager",
    basePackages = {"aaa.xxx"})
 public class RepositoryConfig {
@Autowired
private Environment env;

@Bean
@Primary
@ConfigurationProperties(prefix="datasource.xxx")
public DataSource xxxDataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
public LocalContainerEntityManagerFactoryBean xxxEntityManager() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(xxxDataSource());
    em.setPackagesToScan(new String[] {"aaa.xxx"});

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<String, Object> properties = new HashMap<String, Object>();
    properties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
    properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
    properties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
    em.setJpaPropertyMap(properties);

    return em;
}

@Bean(name = "xxxTransactionManager")
public PlatformTransactionManager xxxTransactionManager() {
    JpaTransactionManager tm = new JpaTransactionManager();
    tm.setEntityManagerFactory(xxxEntityManager().getObject());
    return tm;
}

}

You use EXECUTENONQUERY() for INSERT,UPDATE and DELETE.

But for SELECT you must use EXECUTEREADER().........

For completeness, if "AllowOverride All" doesn't fix your problem, you could debug this problem using:

1. Run apachectl -S and see if you have more than one namevhost. It might be that httpd is looking for .htaccess of another DocumentRoot.

2. Use strace -f apachectl -X and look for where it's loading (or not loading) .htaccess from.

Try this:

try
{
    DirectoryInfo di = new DirectoryInfo(path);
    DirectorySecurity acl = di.GetAccessControl();
    AuthorizationRuleCollection rules = acl.GetAccessRules(true, true, typeof(NTAccount));

    WindowsIdentity currentUser = WindowsIdentity.GetCurrent();
    WindowsPrincipal principal = new WindowsPrincipal(currentUser);
    foreach (AuthorizationRule rule in rules)
    {
        FileSystemAccessRule fsAccessRule = rule as FileSystemAccessRule;
        if (fsAccessRule == null)
            continue;

        if ((fsAccessRule.FileSystemRights & FileSystemRights.WriteData) > 0)
        {
            NTAccount ntAccount = rule.IdentityReference as NTAccount;
            if (ntAccount == null)
            {
                continue;
            }

            if (principal.IsInRole(ntAccount.Value))
            {
                Console.WriteLine("Current user is in role of {0}, has write access", ntAccount.Value);
                continue;
            }
            Console.WriteLine("Current user is not in role of {0}, does not have write access", ntAccount.Value);                        
        }
    }
}
catch (UnauthorizedAccessException)
{
    Console.WriteLine("does not have write access");
}

System.Threading.Thread.Sleep(
    (int)System.TimeSpan.FromSeconds(3).TotalMilliseconds);

Or with using statements:

Thread.Sleep((int)TimeSpan.FromSeconds(2).TotalMilliseconds);

I prefer this to 1000 * numSeconds (or simply 3000) because it makes it more obvious what is going on to someone who hasn't used Thread.Sleep before. It better documents your intent.

you can check by putting these code in php file.

<?php
if(in_array  ('curl', get_loaded_extensions())) {
    echo "CURL is available on your web server";
}
else{
    echo "CURL is not available on your web server";
}

OR

var_dump(extension_loaded('curl'));

I had the same error when I imported web requests from fiddler captured sessions to Visual Studio webtests. Some POST requests did not have a StringHttpBody tag. I added an empty one to them and the error was gone. Add this after the Headers tag:

    <StringHttpBody ContentType="" InsertByteOrderMark="False">
  </StringHttpBody>

You do not need to use an anonymous function with setTimeout. You can do something like this:

setTimeout(doSomething, 3000);

function doSomething() {
   //do whatever you want here
}

You need to define the width of the element you are centering, not the parent element.

#header ul {
    margin: 0 auto;
    width: 90%;
}

Edit: Ok, I've seen the testpage now, and here is how I think you want it:

#header ul {
    list-style:none;
    margin:0 auto;
    width:90%;
}

/* Remove the float: left; property, it interferes with display: inline and 
 * causes problems. (float: left; makes the element implicitly a block-level
 * element. It is still good to use display: inline on it to overcome a bug
 * in IE6 and below that doubles horizontal margins for floated elements)
 * The styles below is the full style for the list-items. 
 */
#header ul li {
    color:#CCCCCC;
    display:inline;
    font-size:20px;
    padding-right:20px;
}

I am using pandas.

import pandas as pd
x = pd.Series([1,2,3,4,5])
x.to_excel('temp.xlsx')
y = list(pd.read_excel('temp.xlsx')[0])
print(y)

Use this if you are anyway importing pandas for other computations.

So after a number of tries, I found it working.

Please follow the order sequence it's very important else it won't work

axios.delete(URL, {
  headers: {
    Authorization: authorizationToken
  },
  data: {
    source: source
  }
});

For python 3.5+ it is recommended that you use the run function from the subprocess module. This returns a CompletedProcess object, from which you can easily obtain the output as well as return code.

from subprocess import PIPE, run

command = ['echo', 'hello']
result = run(command, stdout=PIPE, stderr=PIPE, universal_newlines=True)
print(result.returncode, result.stdout, result.stderr)

Don't mix HTTP and HTTPS on the same page. If you have a form page that is served up via HTTP, I'm going to be nervous about submitting data -- I can't see if the submit goes over HTTPS or HTTP without doing a View Source and hunting for it.

Serving up the form over HTTPS along with the submit link isn't that heavy a change for the advantage.

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.
