You have to loop through every cell in the range "D3:D6" and construct your To string. Simply assigning it to a variant will not solve the purpose. EmailTo becomes an array if you assign the range directly to it. You can do this as well but then you will have to loop through the array to create your To string

Is this what you are trying? (TRIED AND TESTED)

This probably does not answer your question, but I had the same question and it answered mine.

I changed Private Function to Public Function and it worked.

prefix the comment with a single-quote. there is no need for an "end" tag.

'this is a comment

Extend to multiple lines using the line-continuation character, _:

'this is a multi-line _
   comment

This is an option in the toolbar to select a line(s) of code and comment/uncomment:

SMTP error 554 is one of the more vague error codes, but is typically caused by the receiving server seeing something in the From or To headers that it doesn't like. This can be caused by a spam trap identifying your machine as a relay, or as a machine not trusted to send mail from your domain.

We ran into this problem recently when adding a new server to our array, and we fixed it by making sure that we had the correct reverse DNS lookup set up.

There is something explained here :

https://web.archive.org/web/20140608170948/http://www.campaignmonitor.com:80/blog/post/3363/updated-applying-a-background-image-to-html-email

This code will add an event listener to the default local Inbox, then take some action on incoming emails. You need to add that action in the code below.

Private WithEvents Items As Outlook.Items 
Private Sub Application_Startup() 
  Dim olApp As Outlook.Application 
  Dim objNS As Outlook.NameSpace 
  Set olApp = Outlook.Application 
  Set objNS = olApp.GetNamespace("MAPI") 
  ' default local Inbox
  Set Items = objNS.GetDefaultFolder(olFolderInbox).Items 
End Sub
Private Sub Items_ItemAdd(ByVal item As Object) 

  On Error Goto ErrorHandler 
  Dim Msg As Outlook.MailItem 
  If TypeName(item) = "MailItem" Then
    Set Msg = item 
    ' ******************
    ' do something here
    ' ******************
  End If
ProgramExit: 
  Exit Sub
ErrorHandler: 
  MsgBox Err.Number & " - " & Err.Description 
  Resume ProgramExit 
End Sub

After pasting the code in ThisOutlookSession module, you must restart Outlook.

You should definitely check out the MSDN on what Outlook will support in regards to css and html. The link is here: http://msdn.microsoft.com/en-us/library/aa338201(v=office.12).aspx. If you do not have at least office 2007 you really need to upgrade as there are major differences between 2007 and previous editions. Also try saving the resulting email to file and examine it with firefox you will see what is being changed by outlook and possibly have a more specific question to ask. You can use Word to view the email as a sort of preview as well (but you won't get info on what styles are/are not being applied.

For a solution that uses outlook see TheoretiCAL's answer below.

Otherwise, use the smtplib that comes with python. Note that this will require your email account allows smtp, which is not necessarily enabled by default.

SERVER = "smtp.example.com"
FROM = "[email protected]"
TO = ["listOfEmails"] # must be a list

SUBJECT = "Subject"
TEXT = "Your Text"

# Prepare actual message
message = """From: %s\r\nTo: %s\r\nSubject: %s\r\n\

%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)

# Send the mail
import smtplib
server = smtplib.SMTP(SERVER)
server.sendmail(FROM, TO, message)
server.quit()

EDIT: this example uses reserved domains like described in RFC2606

SERVER = "smtp.example.com"
FROM = "[email protected]"
TO = ["[email protected]"] # must be a list

SUBJECT = "Hello!"
TEXT = "This is a test of emailing through smtp of example.com."

# Prepare actual message
message = """From: %s\r\nTo: %s\r\nSubject: %s\r\n\

%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)

# Send the mail
import smtplib
server = smtplib.SMTP(SERVER)
server.login("MrDoe", "PASSWORD")
server.sendmail(FROM, TO, message)
server.quit()

_{For it to actually work with gmail, Mr. Doe will need to go to the options tab in gmail and set it to allow smtp connections.}

Note the addition of the login line to authenticate to the remote server. The original version does not include this, an oversight on my part.

All styling including padding have to be added to a td not a span.

Another solution put the text into <p>text</p> and define margins, and that should give the required padding.

For example:

<p style="margin-top: 10px; margin-bottom: 10; margin-right: 12; margin-left: 12;">text</p>

Here's what works for me, and is quickest and causes the least amount of pain / annoyance:

1) Paste you code snippet into sublime; make sure your syntax is looking good.

2) Right click and choose 'Copy as RTF'

3) Paste into your email

4) Done

FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :

strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

Option 1
You didn't say much about your environment, but assuming you have it available you could use a PowerShell script; one example is here. The essence of this is:

$smtp = New-Object Net.Mail.SmtpClient("ho-ex2010-caht1.exchangeserverpro.net")
$smtp.Send("[email protected]","[email protected]","Test Email","This is a test")

You could then launch the script from the command line as per this example:

powershell.exe -noexit c:\scripts\test.ps1

Note that PowerShell 2.0, which is installed by default on Windows 7 and Windows Server 2008R2, includes a simpler Send-MailMessage command, making things easier.

Option 2
If you're prepared to use third-party software, is something line this SendEmail command-line tool. It depends on your target environment, though; if you're deploying your batch file to multiple machines, that will obviously require inclusion (but not formal installation) each time.

Option 3
You could drive Outlook directly from a VBA script, which in turn you would trigger from a batch file; this would let you send an email using Outlook itself, which looks to be closest to what you're wanting. There are two parts to this; first, figure out the VBA scripting required to send an email. There are lots of examples for this online, including from Microsoft here. Essence of this is:

Sub SendMessage(DisplayMsg As Boolean, Optional AttachmentPath)
    Dim objOutlook As Outlook.Application
    Dim objOutlookMsg As Outlook.MailItem
    Dim objOutlookRecip As Outlook.Recipient
    Dim objOutlookAttach As Outlook.Attachment

    Set objOutlook = CreateObject("Outlook.Application")
    Set objOutlookMsg  = objOutlook.CreateItem(olMailItem)

    With objOutlookMsg
        Set objOutlookRecip = .Recipients.Add("Nancy Davolio")
        objOutlookRecip.Type = olTo
        ' Set the Subject, Body, and Importance of the message.
        .Subject = "This is an Automation test with Microsoft Outlook"
        .Body = "This is the body of the message." &vbCrLf & vbCrLf
        .Importance = olImportanceHigh  'High importance

        If Not IsMissing(AttachmentPath) Then
            Set objOutlookAttach = .Attachments.Add(AttachmentPath)
        End If

        For Each ObjOutlookRecip In .Recipients
            objOutlookRecip.Resolve
        Next

        .Save
        .Send
    End With
    Set objOutlook = Nothing
End Sub

Then, launch Outlook from the command line with the /autorun parameter, as per this answer (alter path/macroname as necessary):

C:\Program Files\Microsoft Office\Office11\Outlook.exe" /autorun macroname

Option 4
You could use the same approach as option 3, but move the Outlook VBA into a PowerShell script (which you would run from a command line). Example here. This is probably the tidiest solution, IMO.

Added simple code to save with readable date-time stamp.

Use sync2pst to sync all your data in outlook with all your devices, work like this:

1. you only need to buy 1 license: save your pst file on one computer (let's call this pc 'server') on your network.
2. create scheduled tasks that will synchronize the pst file on your 'server' with all the pst files on all your devices, no matter which device downloaded the emails first (you need some dos programming knowledge to bypass pst files that are open at sync time).
3. save all your attachments on the same skydrive folder that is located on the same place on all your devices (e.g. e:\skydrive\attachments)
4. Use the code below on all your devices to save attachments (change the path as mentioned above)

5. Use ONLY ONE PST-file for all your accounts, make folders, subfolders and so ...

6. in VBA: refer to 'microsoft scripting runtime'extra/references...'

7. here's the code

Private Sub Application_NewMail()
SaveAttachments
End Sub

Dim objMsg As Outlook.MailItem 'Object

            objAttachments.Item(i).SaveAsFile strFile

            ' Delete the attachment.

            'write the save as path to a string to add to the message

            If objMsg.BodyFormat <> olFormatHTML Then
                strDeletedFiles = strDeletedFiles & vbCrLf & "<file://" & strFile & ">"
            Else
                strDeletedFiles = strDeletedFiles & "<br>" & "<a href='file://" & _
                strFile & "'>" & strFile & "</a>"
            End If

            'Use the MsgBox command to troubleshoot. Remove it from the final code.
            'MsgBox strDeletedFiles

        Next i

        ' Adds the filename string to the message body and save it
        ' Check for HTML body

        Else
            objMsg.HTMLBody = "<p>" & "The file(s) were saved to " & strDeletedFiles & "</p>" & objMsg.HTMLBody

make the image the exact size needed in the email. Windows MSO has a hard time resizing images in different scenarios.

in the case of using a 1px by 1px transparent png or gif as a spacer, defining the dimensions via width, height, or style attributes will work as expected in the majority of clients, but not windows MSO (of course).

example use case - you are using a background image and need to position a with a link inside over some part of the background image. Using a 1px by 1px spacer gif/png will only expand so wide (about 30px). You need size the spacer to the exact dimensions.

Add a reference to the Outlook object model in the Visual Basic editor. Then you can use the code below to send an email using outlook.

Sub sendOutlookEmail()
Dim oApp As Outlook.Application
Dim oMail As MailItem
Set oApp = CreateObject("Outlook.application")

Set oMail = oApp.CreateItem(olMailItem)
oMail.Body = "Body of the email"
oMail.Subject = "Test Subject"
oMail.To = "[email protected]"
oMail.Send
Set oMail = Nothing
Set oApp = Nothing


End Sub

New introduction 2

In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:

Set FolderTgt = CreateObject("Outlook.Application"). _
              GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)

I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.

This macro, outputs the name of the store holding the default Inbox to the Immediate Window:

Sub DsplUsernameOfDefaultStore()

  Dim NS As Outlook.NameSpace
  Dim DefaultInboxFldr As MAPIFolder

  Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
  Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)

  Debug.Print DefaultInboxFldr.Parent.Name

End Sub

On my installation, this outputs: "Outlook Data File".

I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.

New introduction 1

A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.

The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)

Original text

There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.

For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.

What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.

The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.

The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:

Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.

All other comments containing hashes suggest amendments to adapt the macro to your requirements.

How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed".

The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.

This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:

Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on

Extracting the values from the original of this string should not be difficult.

I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.

Good luck.

Now there is a nuget package for that.

https://www.nuget.org/packages/NetOffice.Core.Net40/

First I didn't find office in COM, so tried this nuget and it worked!

I had the same issue. Combining various approaches from the internet (and above) come up with the following approach (checkEmails.py)

class CheckMailer:

        def __init__(self, filename="LOG1.txt", mailbox="Mailbox - Another User Mailbox", folderindex=3):
            self.f = FileWriter(filename)
            self.outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI").Folders(mailbox)
            self.inbox = self.outlook.Folders(folderindex)


        def check(self):                
        #===============================================================================
        # for i in xrange(1,100):                           #Uncomment this section if index 3 does not work for you
        #     try:
        #         self.inbox = self.outlook.Folders(i)     # "6" refers to the index of inbox for Default User Mailbox
        #         print "%i %s" % (i,self.inbox)            # "3" refers to the index of inbox for Another user's mailbox
        #     except:
        #         print "%i does not work"%i
        #===============================================================================

                self.f.pl(time.strftime("%H:%M:%S"))
                tot = 0                
                messages = self.inbox.Items
                message = messages.GetFirst()
                while message:
                    self.f.pl (message.Subject)
                    message = messages.GetNext()
                    tot += 1
                self.f.pl("Total Messages found: %i" % tot)
                self.f.pl("-" * 80)
                self.f.flush()

if __name__ == "__main__":
    mail = CheckMailer()
    for i in xrange(320):  # this is 10.6 hours approximately
            mail.check()
            time.sleep(120.00)

For concistency I include also the code for the FileWriter class (found in FileWrapper.py). I needed this because trying to pipe UTF8 to a file in windows did not work.

class FileWriter(object):
    '''
    convenient file wrapper for writing to files
    '''


    def __init__(self, filename):
        '''
        Constructor
        '''
        self.file = open(filename, "w")

    def pl(self, a_string):
        str_uni = a_string.encode('utf-8')
        self.file.write(str_uni)
        self.file.write("\n")

    def flush(self):
        self.file.flush()

I like Mozzi's answer but found that it did not retain the default fonts that are user specific. The text all appeared in a system font as normal text. The code below retains the user's favourite fonts, while making it only a little longer. It is based on Mozzi's approach, uses a regular expression to replace the default body text and places the user's chosen Body text where it belongs by using GetInspector.WordEditor. I found that the call to GetInspector did not populate the HTMLbody as dimitry streblechenko says above in this thread, at least, not in Office 2010, so the object is still displayed in my code. In passing, please note that it is important that the MailItem is created as an Object, not as a straightforward MailItem - see here for more. (Oh, and sorry to those of different tastes, but I prefer longer descriptive variable names so that I can find routines!)

This is what I do, just add \n and use encodeURIComponent

Example

var emailBody = "1st line.\n 2nd line \n 3rd line";

emailBody = encodeURIComponent(emailBody);

href = "mailto:[email protected]?body=" + emailBody;

Check encodeURIComponent docs

if the message is text/plain using, \r\n should work; if the message type is text\html, use < p/>

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:

@Adrian Cornish's answer is correct. However, there is another caveat to dropping an existing primary key. If that primary key is being used as a foreign key by another table you will get an error when trying to drop it. In some versions of mysql the error message there was malformed (as of 5.5.17, this error message is still

alter table parent  drop column id;
ERROR 1025 (HY000): Error on rename of
'./test/#sql-a04_b' to './test/parent' (errno: 150).

If you want to drop a primary key that's being referenced by another table, you will have to drop the foreign key in that other table first. You can recreate that foreign key if you still want it after you recreate the primary key.

Also, when using composite keys, order is important. These

1) ALTER TABLE provider ADD PRIMARY KEY(person,place,thing);
and
2) ALTER TABLE provider ADD PRIMARY KEY(person,thing,place);

are not the the same thing. They both enforce uniqueness on that set of three fields, however from an indexing standpoint there is a difference. The fields are indexed from left to right. For example, consider the following queries:

A) SELECT person, place, thing FROM provider WHERE person = 'foo' AND thing = 'bar';
B) SELECT person, place, thing FROM provider WHERE person = 'foo' AND place = 'baz';
C) SELECT person, place, thing FROM provider WHERE person = 'foo' AND place = 'baz' AND thing = 'bar';
D) SELECT person, place, thing FROM provider WHERE place = 'baz' AND thing = 'bar';

B can use the primary key index in ALTER statement 1
A can use the primary key index in ALTER statement 2
C can use either index
D can't use either index

A uses the first two fields in index 2 as a partial index. A can't use index 1 because it doesn't know the intermediate place portion of the index. It might still be able to use a partial index on just person though.

D can't use either index because it doesn't know person.

See the mysql docs here for more information.

Maybe this will help... this was used in the full size jQuery calendar click event (http://arshaw.com/fullcalendar/)... but it can be used more generally to deal with fancybox being launched by jQuery.

  eventClick: function(calEvent, jsEvent, view) {
      jQuery("body").after('<a id="link_'+calEvent.url+'" style="display: hidden;" href="http://thisweekinblackness.com/wp-content/uploads/2009/01/steve-urkel.jpg">Steve</a>');
      jQuery('#link_'+calEvent.url).fancybox(); 
      jQuery('#link_'+calEvent.url).click();
      jQuery('#link_'+calEvent.url).remove();
    return false;
  }

The vector you are creating is neither row nor column. It actually has 1 dimension only. You can verify that by

• checking the number of dimensions myvector.ndim which is 1
• checking the myvector.shape, which is (3,) (a tuple with one element only). For a row vector is should be (1, 3), and for a column (3, 1)

Two ways to handle this

• create an actual row or column vector
• reshape your current one

You can explicitly create a row or column

row = np.array([    # one row with 3 elements
   [1, 2, 3]
]
column = np.array([  # 3 rows, with 1 element each
    [1],
    [2],
    [3]
])

or, with a shortcut

row = np.r_['r', [1,2,3]]     # shape: (1, 3)
column = np.r_['c', [1,2,3]]  # shape: (3,1)

Alternatively, you can reshape it to (1, n) for row, or (n, 1) for column

row = my_vector.reshape(1, -1)
column = my_vector.reshape(-1, 1)

where the -1 automatically finds the value of n.

Settings -> Advanced, add url to "Valid OAuth redirect URIs". This works for me.

Circular imports cause problems, but Python has ways to mitigate it built-in.

The problem is when you run python a.py, it runs a.py but not mark it imported as a module. So in turn a.py -> imports module b -> imports module a -> imports module b. The last import a no-op since b is currently being imported and Python guards against that. And b is an empty module for now. So when it executes b.hi(), it can't find anything.

Note that the b.hi() that got executed is during a.py -> module b -> module a, not in a.py directly.

In your specific example, you can just run python -c 'import a' at top-level, so the first execution of a.py is registered as importing a module.

To go one step further, you could declare a type pointer to a function signature like:

interface myCallbackType { (myArgument: string): void }

and use it like this:

public myCallback : myCallbackType;

    import urllib2

Traceback (most recent call last):

File "", line 1, in

    import urllib2

ImportError: No module named 'urllib2' So urllib2 has been been replaced by the package : urllib.request.

Here is the PEP link (Python Enhancement Proposals )

http://www.python.org/dev/peps/pep-3108/#urllib-package

so instead of urllib2 you can now import urllib.request and then use it like this:

    >>>import urllib.request

    >>>urllib.request.urlopen('http://www.placementyogi.com')

To find out what ports rabbitmq uses:

$ epmd -names

Outputs:

epmd: up and running on port 4369 with data:
name rabbit at port 25672

Run these as root:

lsof -i :4369
lsof -i :25672

More about epmd options.

What did you expect the following to do?

v1 = [0,0],[M[i,0],M[i,1]]
v1 = [M[i,0]],[M[i,1]]

This is making two different tuples, and you overwrite what you did the first time... Anyway, matplotlib does not understand what a "vector" is in the sense you are using. You have to be explicit, and plot "arrows":

In [5]: ax = plt.axes()

In [6]: ax.arrow(0, 0, *v1, head_width=0.05, head_length=0.1)
Out[6]: <matplotlib.patches.FancyArrow at 0x114fc8358>

In [7]: ax.arrow(0, 0, *v2, head_width=0.05, head_length=0.1)
Out[7]: <matplotlib.patches.FancyArrow at 0x115bb1470>

In [8]: plt.ylim(-5,5)
Out[8]: (-5, 5)

In [9]: plt.xlim(-5,5)
Out[9]: (-5, 5)

In [10]: plt.show()

Result:

Customizable Pretty XML output with UTF-8 XML declaration

The following class definition gives a simple method to convert an input XML string into formatted output XML with the xml declaration as UTF-8. It supports all the configuration options that the XmlWriterSettings class offers.

using System;
using System.Text;
using System.Xml;
using System.IO;

namespace CJBS.Demo
{
    /// <summary>
    /// Supports formatting for XML in a format that is easily human-readable.
    /// </summary>
    public static class PrettyXmlFormatter
    {

        /// <summary>
        /// Generates formatted UTF-8 XML for the content in the <paramref name="doc"/>
        /// </summary>
        /// <param name="doc">XmlDocument for which content will be returned as a formatted string</param>
        /// <returns>Formatted (indented) XML string</returns>
        public static string GetPrettyXml(XmlDocument doc)
        {
            // Configure how XML is to be formatted
            XmlWriterSettings settings = new XmlWriterSettings 
            {
                Indent = true
                , IndentChars = "  "
                , NewLineChars = System.Environment.NewLine
                , NewLineHandling = NewLineHandling.Replace
                //,NewLineOnAttributes = true
                //,OmitXmlDeclaration = false
            };

            // Use wrapper class that supports UTF-8 encoding
            StringWriterWithEncoding sw = new StringWriterWithEncoding(Encoding.UTF8);

            // Output formatted XML to StringWriter
            using (XmlWriter writer = XmlWriter.Create(sw, settings))
            {
                doc.Save(writer);
            }

            // Get formatted text from writer
            return sw.ToString();
        }



        /// <summary>
        /// Wrapper class around <see cref="StringWriter"/> that supports encoding.

            /// <summary>

            /// </summary>
            /// <param name="encoding"></param>
            public StringWriterWithEncoding(Encoding encoding)
            {
                this.encoding = encoding;
            }

            /// <summary>
            /// Encoding to use when dealing with text
            /// </summary>
            public override Encoding Encoding
            {
                get { return encoding; }
            }
        }
    }
}

Possibilities for further improvement:-

• An additional method GetPrettyXml(XmlDocument doc, XmlWriterSettings settings) could be created that allows the caller to customize the output.
• An additional method GetPrettyXml(String rawXml) could be added that supports parsing raw text, rather than have the client use the XmlDocument. In my case, I needed to manipulate the XML using the XmlDocument, hence I didn't add this.

Usage:

String myFormattedXml = null;
XmlDocument doc = new XmlDocument();
try
{
    doc.LoadXml(myRawXmlString);
    myFormattedXml = PrettyXmlFormatter.GetPrettyXml(doc);
}
catch(XmlException ex)
{
    // Failed to parse XML -- use original XML as formatted XML
    myFormattedXml = myRawXmlString;
}

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')

One liner for callstack:

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace; end

One liner for callstack without all the gems's:

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace.grep_v(/\/gems\//); end

One liner for callstack without all the gems's and relative to current directory

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace.grep_v(/\/gems\//).map { |l| l.gsub(`pwd`.strip + '/', '') }; end

Use string's split() method.

states.split()

TL;DR Use Cmd/Ctrl+Shift+P then Package Control: Install Package, then Print to HTML and install it. Use Alt+Shift+P to print.

My favorite tool for printing from Sublime Text is Print to HTML package. You can "print" a selection or a whole file - via the web browser.

Usage

1. Make a selection (or none for the whole file)
2. Press Alt+Shift+P OR Shift+Command+P and type in "Print to HTML".

This opens your browser print dialog (Chrome for me) with the selected text neatly in the print dialog window and syntax highlighting intact. There you can choose a printer or export to PDF, and print.

Setup

Install the "Print to HTML" package using the package manager.

1. Ctrl + Shift + P => Gives a list of commands.
2. Find the package manager by typing "install"
3. You see a few choices. Select "Package Control: Install Package"
4. This opens a list of packages. Type "print to"
5. One of the choices should be "Print to HTML". Select that, and it is being installed.
6. You can use the "print to html" now by a keyboard shortcut Alt+Shift+P

Well, it would be more accurate to rely on the feature and not a variable value. Especially as there are 2 possible variables for Windows.

function getUserHome() {
  return process.env.HOME || process.env.USERPROFILE;
}

EDIT: as mentioned in a more recent answer, https://stackoverflow.com/a/32556337/103396 is the right way to go (require('os').homedir()).

Using a CLI, the easiest way (cross-platform) I've found is to use the NPM package https://github.com/sindresorhus/open-cli

npm install --global open-cli

Installing it globally allows running something like open-cli https://unlyed.github.io/next-right-now/.

You can also install it locally (e.g: in a project) and run npx open-cli https://unlyed.github.io/next-right-now/

Or, using a NPM script (which is how I actually use it): "doc:online": "open-cli https://unlyed.github.io/next-right-now/",

Running yarn doc:online will open the webpage, and this works on any platform (windows, mac, linux).

if you already have that hidden input :

function product(a, b) {
   return a * b;
}
function setInputValue(input_id, val) {
    document.getElementById(input_id).setAttribute('value', val);
}

if not, you can create one, add it to the body and then set it's value :

function addInput(val) {
    var input = document.createElement('input');
    input.setAttribute('type', 'hidden');
    input.setAttribute('value', val);
    document.body.appendChild(input);
}

And then you can use(depending on the case) :

addInput(product(2, 3)); // if you want to create the input
// or
setInputValue('input_id', product(2, 3)); 

If trigger("chosen:updated"); not working, use .trigger("liszt:updated"); of @Nhan Tran it is working fine.

You can use this method to send whatever confirmation message you want like "OK" or the password. This is my solution with an example:

def SpecialConfirmation(command, message, reply):
    net_connect.config_mode()    # To enter config mode
    net_connect.remote_conn.sendall(str(command)+'\n' )
    time.sleep(3)
    output = net_connect.remote_conn.recv(65535).decode('utf-8')
    ReplyAppend=''
    if str(message) in output:
        for i in range(0,(len(reply))):
            ReplyAppend+=str(reply[i])+'\n'
        net_connect.remote_conn.sendall(ReplyAppend)
        output = net_connect.remote_conn.recv(65535).decode('utf-8') 
    print (output)
    return output

CryptoPkiEnroll=['','','no','no','yes']

output=SpecialConfirmation ('crypto pki enroll TCA','Password' , CryptoPkiEnroll )
print (output)

If you only specify a literal, there is no difference. LEA has more abilities, though, and you can read about them here:

For some, this may help you guys: I had a similar experience with Wordpress REST API. I even used Postman to check if I had the correct routes or endpoint. I later found out that I accidentally put an "echo" inside my script - hooks:

Debug & check your console

Cause of the error

So basically, this means that I printed a value that isn't JSON that is mixed with the script that causes AJAX error - "SyntaxError: Unexpected token r in JSON at position 0"

you can receive the session id by issuing the following regular expression on document.cookie:

alert(document.cookie.match(/PHPSESSID=[^;]+/));

in my example the cookie name to store session id is PHPSESSID (php server), just replace the PHPSESSID with the cookie name that holds the session id. (configurable by the web server)

You can access elements using $document ($document need to be injected)

var target = $document('#appBusyIndicator');
var target = $document('appBusyIndicator');

or with angular element, the specified elements can be accessed as:

var targets = angular.element(document).find('div'); //array of all div
var targets = angular.element(document).find('p');
var target = angular.element(document).find('#appBusyIndicator');

Regarding Jay Stevens answer: "The fonts available to use in an HTML file have to be present on the user's machine and accessible from the web browser, so unless you want to distribute the fonts to the user's machine via a separate external process, it can't be done." That's true.

But there is another way using javascript / canvas / flash - very good solution gives cufon: http://cufon.shoqolate.com/generate/ library that generates a very easy to use external fonts methods.

In version 0.2.13, You should be able to pass objects into $state.go,

$state.go('myState', {myParam: {some: 'thing'}})

$stateProvider.state('myState', {
                url: '/myState/{myParam:json}',
                params: {myParam: null}, ...

and then access the parameter in your controller.

$stateParams.myParam //should be {some: 'thing'}

myParam will not show up in the URL.

Source:

See the comment by christopherthielen https://github.com/angular-ui/ui-router/issues/983, reproduced here for convenience:

christopherthielen: Yes, this should be working now in 0.2.13.

.state('foo', { url: '/foo/:param1?param2', params: { param3: null } // null is the default value });

$state.go('foo', { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } });

$stateParams in 'foo' is now { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } }

url is /foo/bar?param2=baz.

You can use jstat, like :

 jstat -gc pid

On python 3.6 with django 2.0, decode on a byte literal does not works as expected. Yeah i get the right result when i print it, but the b'value' is still there even if you print it right.

This is what im encoding

uid': urlsafe_base64_encode(force_bytes(user.pk)),

This is what im decoding:

uid = force_text(urlsafe_base64_decode(uidb64))

This is what django 2.0 says :

urlsafe_base64_encode(s)[source]

Encodes a bytestring in base64 for use in URLs, stripping any trailing equal signs.

urlsafe_base64_decode(s)[source]

Decodes a base64 encoded string, adding back any trailing equal signs that might have been stripped.

now it works fine. :)

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

@Sheridan thx.. if I try your example with "DisplayedImagePath" on both sides, it works with absolute path as you show.

As for the relative paths, this is how I always connect relative paths, I first include the subdirectory (!) and the image file in my project.. then I use ~ character to denote the bin-path..

    public string DisplayedImagePath
    {
        get { return @"~\..\images\osc.png"; }
    }

This was tested, see below my Solution Explorer in VS2015..

)

Note: if you want a Click event, use the Button tag around the image,

<Button Click="image_Click" Width="128" Height="128"  Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left">_x000D_
  <Image x:Name="image" Source="{Binding DisplayedImagePath}" Margin="0,0,0,0" />_x000D_
</Button>

Here I found a solution by comparing buttons in a button-group element. The simple solution is to get the one with the largest width and set the width to the other buttons. So they can have a equal width.

    function EqualizeButtons(parentElementId) {

    var longest = 0; 
    var element = $(parentElementId);

    element.find(".btn:not(.button-controlled)").each(function () {
        $(this).addClass('button-controlled');
        var width = $(this).width();
        if (longest < width) longest = width;

    }).promise().done(function () {
        $('.button-controlled').width(longest);
    });
}

It worked like a charm.

If you don't want to build your server side, like only developing on a client side (web app or a mobile app) , you could choose an Implicit Authentication .

As the document saying , first make a https request with

https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=token

Fill in your CLIENT-ID and REDIRECT-URL you designated.

Then that's going to the log in page , but the most important thing is how to get the access token after the user correctly logging in.

After the user click the log in button with both correct account and password, the web page will redirect to the url you designated followed by a new access token.

http://your-redirect-uri#access_token=ACCESS-TOKEN

I'm not familiar with javascript , but in Android studio , that's an easy way to add a listener which listen to the event the web page override the url to the new url (redirect event) , then it will pass the redirect url string to you , so you can easily split it to get the access-token like:

String access_token = url.split("=")[1];

Means to break the url into the string array in each "=" character , then the access token obviously exists at [1].

Try this:

{[0-9]{1,3}:[0-9]{1,3}}

The {1,3} means "match between 1 and 3 of the preceding characters".

You can accomplish what you want with either:

docker run -t -d <image-name>

or

docker run -i -d <image-name>

or

docker run -it -d <image-name>

The command parameter as suggested by other answers (i.e. tail -f /dev/null) is completely optional, and is NOT required to get your container to stay running in the background.

Also note the Docker documentation suggests that combining -i and -t options will cause it to behave like a shell.

See:

https://docs.docker.com/engine/reference/run/#foreground

Since -f caused another problem, I developed another solution.

• Create a base image in the parent folder
• Added the required files.
• Used this image as a base image for the project which in a descendant folder.

The -f flag does not solved my problem because my onbuild image looks for a file in a folder and had to call like this:

-f foo/bar/Dockerfile foo/bar

instead of

-f foo/bar/Dockerfile .

Also note that this is only solution for some cases as -f flag

• To list all unstaged tracked changed files:

  git diff --name-only
  

• To list all staged tracked changed files:

  git diff --name-only --staged
  

• To list all staged and unstaged tracked changed files:

  { git diff --name-only ; git diff --name-only --staged ; } | sort | uniq
  

• To list all untracked files (the ones listed by git status, so not including any ignored files):

  git ls-files --other --exclude-standard
  

If you're using this in a shell script, and you want to programmatically check if these commands returned anything, you'll be interested in git diff's --exit-code option.

You can add it from the notepad++ toolbar Plugins > Plugin Manager > Show Plugin Manager. Then select the Explorer plugin and click the Install button.

I think this error may related to the DNS resolution. This sentence host = socket.gethostname() get the host name, but if the operating system can not resolve the host name to local address, you would get the error. Linux operating system can modify the /etc/hosts file, add one line in it. It looks like below( 'hostname' is which socket.gethostname() got).

For instance, if you want results between 2017-09-05 till 2017-09-09

SELECT DATE(timestamp_field) as date FROM stocks_annc WHERE DATE(timestamp_field) >= '2017-09-05' AND DATE(timestamp_field) <= '2017-09-09'

Make sure to wrap the dates within single quotation ''

Hope this helps.

(variable1, @variable2, ..) SET variable2 = nullif(@variable2, '' or ' ') >> you can put any condition

Hashtags at the end of the URL bring a visitor to the element with the ID: e.g.

http://stackoverflow.com/questions/8424785/link-to-a-section-of-a-webpage#answers 

Would bring you to where the DIV with the ID 'answers' begins. Also, you can use the name attribute in anchor tags, to create the same effect.

Resource

Following the requirements

I have a filename with x number of characters then a five digit sequence surrounded by a single underscore on either side then another set of x number of characters. I want to take the 5 digit number and put that into a variable.

I found some grep ways that may be useful:

$ echo "someletters_12345_moreleters.ext" | grep -Eo "[[:digit:]]+" 
12345

or better

$ echo "someletters_12345_moreleters.ext" | grep -Eo "[[:digit:]]{5}" 
12345

And then with -Po syntax:

$ echo "someletters_12345_moreleters.ext" | grep -Po '(?<=_)\d+' 
12345

Or if you want to make it fit exactly 5 characters:

$ echo "someletters_12345_moreleters.ext" | grep -Po '(?<=_)\d{5}' 
12345

Finally, to make it be stored in a variable it is just need to use the var=$(command) syntax.

import os
import re
from pathlib import Path

for f in os.listdir(training_data_dir2):
  for file in os.listdir( training_data_dir2 + '/' + f):
    oldfile= Path(training_data_dir2 + '/' + f + '/' + file)
    newfile = Path(training_data_dir2 + '/' + f + '/' + file[49:])
    p=oldfile
    p.rename(newfile)

Quote from this post (it's written by the author of doxygen himself) :

run doxygen -g and change the following options of the generated Doxyfile:

    EXTRACT_ALL            = YES
    HAVE_DOT               = YES
    UML_LOOK               = YES

run doxygen again

A good plugin that I have used before is DataTables.

I know this is an old post, but figured I'd share my two cents. @Neji is correct in that you can use sessionStorage.getItem('label'), and sessionStorage.setItem('label', 'value') (although he had the setItem parameters backwards, not a big deal). I much more prefer the following, I think it's more succinct:

var val = sessionStorage.myValue

in place of getItem and

sessionStorage.myValue = 'value'

in place of setItem.

Also, it should be noted that in order to store JavaScript objects, they must be stringified to set them, and parsed to get them, like so:

sessionStorage.myObject = JSON.stringify(myObject); //will set object to the stringified myObject
var myObject = JSON.parse(sessionStorage.myObject); //will parse JSON string back to object

The reason is that sessionStorage stores everything as a string, so if you just say sessionStorage.object = myObject all you get is [object Object], which doesn't help you too much.

ls /bin/python*

Identify the highest version of python listed. If the highest version is something like python2.7 then install python2-pip If its something like python3.8 then install python3-pip

Example for python3.8:

sudo apt-get install python3-pip

Create the following function

CREATE OR REPLACE FUNCTION isnull(text, text) RETURNS text AS 'SELECT (CASE (SELECT $1 "
    "is null) WHEN true THEN $2 ELSE $1 END) AS RESULT' LANGUAGE 'sql'

And it'll work.

You may to create different versions with different parameter types.

Here is a demo react_hooks_debug_print.html in react hooks that is based on Chris's answer. The json data example is from https://json.org/example.html.

      )

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

IMHO, there is difference between checking if a module is:

1) installed, or 2) imported:

To check if installed:

Option 1: Using Get-Module with -ListAvailable parameter:

If(Get-Module -ListAvailable -Name "<ModuleName>"){'Module is installed'}
Else{'Module is NOT installed'}

Option 2: Using $error object:

$error.clear()
Import-Module "<ModuleName>" -ErrorAction SilentlyContinue
If($error){Write-Host 'Module is NOT installed'}
Else{Write-Host 'Module is installed'}

To check if imported:

Using Get-Module with -Name parameter (which you can omit as it is default anyway):

if ((Get-Module -Name "<ModuleName>")) {
   Write-Host "Module is already imported (i.e. its cmdlets are available to be used.)"
}
else {
   Write-Warning "Module is NOT imported (must be installed before importing)."
}

From How do I install a Python package with a .whl file? [sic], How do I install a Python package USING a .whl file ?

For all Windows platforms:

1) Download the .WHL package install file.

2) Make Sure path [C:\Progra~1\Python27\Scripts] is in the system PATH string. This is for using both [pip.exe] and [easy-install.exe].

3) Make sure the latest version of pip.EXE is now installed. At this time of posting:

pip.EXE --version

  pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

4) Run pip.EXE in an Admin command shell.

 - Open an Admin privileged command shell.

 > easy_install.EXE --upgrade  pip

 - Check the pip.EXE version:
 > pip.EXE --version

 pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

 > pip.EXE install --use-wheel --no-index 
     --find-links="X:\path to wheel file\DownloadedWheelFile.whl"

Be sure to double-quote paths or path\filenames with embedded spaces in them ! Alternatively, use the MSW 'short' paths and filenames.

None of the answers so far have given what seems to be the simplest solution.

$('#image_id').load(
  function () {
    //code here
});

As you pointed out in your question it is a documented behavior. I still find it strange though. I use to repopulate the test database and even though I do not rely on the values of identity fields it was a bit of annoying to have different values when populating the database for the first time from scratch and after removing all data and populating again.

A possible solution is to use truncate to clean the table instead of delete. But then you need to drop all the constraints and recreate them afterwards

In that way it always behaves as a newly created table and there is no need to call DBCC CHECKIDENT. The first identity value will be the one specified in the table definition and it will be the same no matter if you insert the data for the first time or for the N-th

The faster way for your case is:

    jTable.repaint(); // Repaint all the component (all Cells).

The optimized way when one or few cell change:

    ((AbstractTableModel) jTable.getModel()).fireTableCellUpdated(x, 0); // Repaint one cell.

This will return the database name, table name, column name and the datatype of the column specified by a database parameter:

declare @database nvarchar(25)
set @database = ''

SELECT cu.table_catalog,cu.VIEW_SCHEMA, cu.VIEW_NAME, cu.TABLE_NAME,   
cu.COLUMN_NAME,c.DATA_TYPE,c.character_maximum_length
from INFORMATION_SCHEMA.VIEW_COLUMN_USAGE as cu
JOIN INFORMATION_SCHEMA.COLUMNS as c
on cu.TABLE_SCHEMA = c.TABLE_SCHEMA and c.TABLE_CATALOG = 
cu.TABLE_CATALOG
and c.TABLE_NAME = cu.TABLE_NAME
and c.COLUMN_NAME = cu.COLUMN_NAME
where cu.TABLE_CATALOG = @database
order by cu.view_name,c.COLUMN_NAME

What about something like this :

cat texte.txt | sed -e 's/\s/,/g' > texte-new.txt

(Yes, with some useless catting and piping ; could also use < to read from the file directly, I suppose -- used cat first to output the content of the file, and only after, I added sed to my command-line)

EDIT : as @ghostdog74 pointed out in a comment, there's definitly no need for thet cat/pipe ; you can give the name of the file to sed :

sed -e 's/\s/,/g' texte.txt > texte-new.txt

If "texte.txt" is this way :

$ cat texte.txt
this is a text
in which I want to replace
spaces by commas

You'll get a "texte-new.txt" that'll look like this :

$ cat texte-new.txt
this,is,a,text
in,which,I,want,to,replace
spaces,by,commas

I wouldn't go just replacing the old file by the new one (could be done with sed -i, if I remember correctly ; and as @ghostdog74 said, this one would accept creating the backup on the fly) : keeping might be wise, as a security measure (even if it means having to rename it to something like "texte-backup.txt")

If you're working with a long list of substrings consisting of full "words" separated by spaces or any other common character, you can be a little clever in your search.

First divide your string into groups of X, then X+1, then X+2, ..., up to Y. X and Y should be the number of words in your substring with the fewest and most words respectively. For example if X is 1 and Y is 4, "Alpha Beta Gamma Delta" becomes:

"Alpha" "Beta" "Gamma" "Delta"

"Alpha Beta" "Beta Gamma" "Gamma Delta"

"Alpha Beta Gamma" "Beta Gamma Delta"

"Alpha Beta Gamma Delta"

If X would be 2 and Y be 3, then you'd omit the first and last row.

Now you can search on this list quickly if you insert it into a Set (or a Map), much faster than by string comparison.

The downside is that you can't search for substrings like "ta Gamm". Of course you could allow for that by splitting by character instead of by word, but then you'd often need to build a massive Set and the time/memory spent doing so outweighs the benefits.

A percentage is just:

(number_one / number_two) * 100

No need for anything fancy:

var number1 = 4.954848;
var number2 = 5.9797;

alert(Math.floor((number1 / number2) * 100)); //w00t!

This is working

<form name="myform" ng-submit="create()">
    <input type="number"
           name="price_field"
           ng-model="price"
           require
           ng-pattern="/^\d{0,9}(\.\d{1,9})?$/">
    <span  ng-show="myform.price_field.$error.pattern">Not valid number!</span>
    <input type="submit" class="btn">
 </form>

I had a similar problem (differences being I wanted to return an object that was already converted to a json string and my controller get returns a IHttpActionResult)

Here is how I solved it. First I declared a utility class

public class RawJsonActionResult : IHttpActionResult
{
    private readonly string _jsonString;

    public RawJsonActionResult(string jsonString)
    {
        _jsonString = jsonString;
    }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var content = new StringContent(_jsonString);
        content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
        var response = new HttpResponseMessage(HttpStatusCode.OK) { Content = content };
        return Task.FromResult(response);
    }
}

This class can then be used in your controller. Here is a simple example

public IHttpActionResult Get()
{
    var jsonString = "{\"id\":1,\"name\":\"a small object\" }";
    return new RawJsonActionResult(jsonString);
}

I found a way if you're going across classes and want the class the method belongs to AND the method. It takes a bit of extraction work but it makes its point. This works in Python 2.7.13.

import inspect, os

class ClassOne:
    def method1(self):
        classtwoObj.method2()

class ClassTwo:
    def method2(self):
        curframe = inspect.currentframe()
        calframe = inspect.getouterframes(curframe, 4)
        print '\nI was called from', calframe[1][3], \
        'in', calframe[1][4][0][6: -2]

# create objects to access class methods
classoneObj = ClassOne()
classtwoObj = ClassTwo()

# start the program
os.system('cls')
classoneObj.method1()

You can have only one default export which you declare like:

export default App; or export default class App extends React.Component {...

and later do import App from './App'

If you want to export something more you can use named exports which you declare without default keyword like:

export {
  About,
  Contact,
}

or:

export About;
export Contact;

or:

export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);

and later you import them like:

import App, { About, Contact } from './App';

EDIT:

There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js file. Other than that why export anything if it is no used outside the file?. Correct main.js :

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router'

class App extends React.Component {
...
}

class Home extends React.Component {
...
}


class About extends React.Component {
...
}


class Contact extends React.Component {
...
}


ReactDOM.render((
   <Router history = {browserHistory}>
      <Route path = "/" component = {App}>
         <IndexRoute component = {Home} />
         <Route path = "home" component = {Home} />
         <Route path = "about" component = {About} />
         <Route path = "contact" component = {Contact} />
      </Route>
   </Router>

), document.getElementById('app'))

EDIT2:

another thing is that this tutorial is based on react-router-V3 which has different api than v4.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.

I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.

# Enable TCP/IP

Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable

# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433

# Modify TCP/IP properties to enable an IP address

$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }

# Restart SQL Server

Restart-Service 'MSSQL$SQLEXPRESS'

I also have this issue and have been looking into it for a long time. It seems that there is no such problem on python 3+. The problem is actually on google.protobuf

Solution 1:

pip uninstall protobuf
pip uninstall google
pip install google
pip install protobuf
pip install google-cloud

Solution 2:

create an __init__.py in "google" folder.

cd /path/to/your/env/lib/python2.7/site-packages/google
touch __init__.py

Hopefully it will work.

What about ordering desc by the desired property,

   blah = blah.OrderByDescending(x => x.Property);

And then doing something like

  if (!descending)
  {
       blah = blah.Reverse()
  }
  else
  {
      // Already sorted desc ;)
  }

Is it Reverse() too slow?

If you're using on a web page, you can also use CSS:

style="text-transform:capitalize;"

because it was only in the comment section I repeat the answer from Eric:

I had to include HTTP_PROVIDERS

I would recommend using a hash instead of a param string:

data = {id: id, name: name}

I had the same problem and no answer in stackoverflow helped. But I found the issue in my project. It was because my .gitignore file contained these lines:

# Package Files #
*.jar
*.war
*.ear

and that is why git did not upload the MyProject\gradle\wrapper\gradle-wrapper.jar file to remote. So, I added this line to .gitignore:

!/gradle/wrapper/gradle-wrapper.jar

Make sure you had this line too. At least this solved my problem

As TF_CPP_MIN_LOG_LEVEL didn't work for me you can try:

tf.logging.set_verbosity(tf.logging.WARN)

Worked for me in tensorflow v1.6.0

Additional Points from above answers

Let’s say we got a module which is shared in multiple apps and it contains a few services. Not all are needed for each app.

If use @Component on those service classes and the component scan in the application,

we might end up detecting more beans than necessary

In this case, you either had to adjust the filtering of the component scan or provide the configuration that even the unused beans can run. Otherwise, the application context won’t start.

In this case, it is better to work with @Bean annotation and only instantiate those beans,

which are required individually in each app

So, essentially, use @Bean for adding third-party classes to the context. And @Component if it is just inside your single application.

A solution for me:

$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
   WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {        
   #Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
$ErrorActionPreference = $old_ErrorActionPreference 

Or use try-catch

try { 

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)

} 
catch {

}

Using Data::Dumper :

use strict;
use Data::Dumper;

my $GRANTstr = 'SELECT, INSERT, UPDATE, DELETE, LOCK TABLES, EXECUTE, TRIGGER';
$GRANTstr    =~ s/, /,/g;
my @GRANTs   = split /,/ , $GRANTstr;

print Dumper(@GRANTs) . "===\n\n";

print Dumper(\@GRANTs) . "===\n\n";

print Data::Dumper->Dump([\@GRANTs], [qw(GRANTs)]);

Generates three different output styles:

$VAR1 = 'SELECT';
$VAR2 = 'INSERT';
$VAR3 = 'UPDATE';
$VAR4 = 'DELETE';
$VAR5 = 'LOCK TABLES';
$VAR6 = 'EXECUTE';
$VAR7 = 'TRIGGER';
===

$VAR1 = [
          'SELECT',
          'INSERT',
          'UPDATE',
          'DELETE',
          'LOCK TABLES',
          'EXECUTE',
          'TRIGGER'
        ];
===

$GRANTs = [
            'SELECT',
            'INSERT',
            'UPDATE',
            'DELETE',
            'LOCK TABLES',
            'EXECUTE',
            'TRIGGER'
          ];

A somewhat unlikely situation.

I have removed the yarn.lock file, which referenced an older version of webpack.

So check to see the differences in your yarn.lock file as a possiblity.

With and ImageBox named "ImagePreview FormStrings.MyImageNames contains a regular get/set string cast method, which are linked to a scrollbox type list. The images have the same names as the linked names on the list, except for the .bmp endings. All bitmaps are dragged into the resources.resx

Object rm = Properties.Resources.ResourceManager.GetObject(FormStrings.MyImageNames);
Bitmap myImage = (Bitmap)rm;
ImagePreview.Image = myImage;

Here's an example where all the logic for waiting until the variable is set gets deferred to a function which then invokes a callback that does everything else the program needs to do - if you need to load variables before doing anything else, this feels like a neat-ish way to do it, so you're separating the variable loading from everything else, while still ensuring 'everything else' is essentially a callback.

var loadUser = function(everythingElse){
    var interval = setInterval(function(){
      if(typeof CurrentUser.name !== 'undefined'){
        $scope.username = CurrentUser.name;
        clearInterval(interval);
        everythingElse();
      }
    },1);
  };

  loadUser(function(){

    //everything else

  });

In a tight loop, it's probably better to avoid regex and hardcode your characters:

const CHARS = new Set("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ");
function isAlphanumeric(char) {
    return CHARS.has(char);
}

I'm working with OS Windows 8.1 and I had the same problem. The source of the problem was the version of Python. I found the origin problem review the file ...\node_modules\mongodb\node_modules\mongodb-core\node_modules\kerberos\builderror.log.

I installed the correct version of Python (2.7.9 for 64 bits) and it resolved my problem.

Note: The installed version of python must be equal or greater than 2.7.5 and less than 3.0.0

C also does a good job at not making anything ambiguous.

Sure the dot could be overloaded to mean both things, but the arrow makes sure that the programmer knows that he's operating on a pointer, just like when the compiler won't let you mix two incompatible types.

I have a simple solution which is working perfectly. The code is not mine, I found it on this link. Here are the steps to follow:

1. Before downloading the image, let’s write a method for saving bitmap into an image file in the internal storage in android. It needs a context, better to use the pass in the application context by getApplicationContext(). This method can be dumped into your Activity class or other util classes.

public void saveImage(Context context, Bitmap b, String imageName) 
{
    FileOutputStream foStream;
    try 
    {
        foStream = context.openFileOutput(imageName, Context.MODE_PRIVATE);
        b.compress(Bitmap.CompressFormat.PNG, 100, foStream);
        foStream.close();
    } 
    catch (Exception e) 
    {
        Log.d("saveImage", "Exception 2, Something went wrong!");
        e.printStackTrace();
    }
}

2. Now we have a method to save bitmap into an image file in andorid, let’s write the AsyncTask for downloading images by url. This private class need to be placed in your Activity class as a subclass. After the image is downloaded, in the onPostExecute method, it calls the saveImage method defined above to save the image. Note, the image name is hardcoded as “my_image.png”.

private class DownloadImage extends AsyncTask<String, Void, Bitmap> {
    private String TAG = "DownloadImage";
    private Bitmap downloadImageBitmap(String sUrl) {
        Bitmap bitmap = null;
        try {
            InputStream inputStream = new URL(sUrl).openStream();   // Download Image from URL
            bitmap = BitmapFactory.decodeStream(inputStream);       // Decode Bitmap
            inputStream.close();
        } catch (Exception e) {
            Log.d(TAG, "Exception 1, Something went wrong!");
            e.printStackTrace();
        }
        return bitmap;
    }

    @Override
    protected Bitmap doInBackground(String... params) {
        return downloadImageBitmap(params[0]);
    }

    protected void onPostExecute(Bitmap result) {
        saveImage(getApplicationContext(), result, "my_image.png");
    }
}

3. The AsyncTask for downloading the image is defined, but we need to execute it in order to run that AsyncTask. To do so, write this line in your onCreate method in your Activity class, or in an onClick method of a button or other places you see fit.

new DownloadImage().execute("http://developer.android.com/images/activity_lifecycle.png");

The image should be saved in /data/data/your.app.packagename/files/my_image.jpeg, check this post for accessing this directory from your device.

IMO this solves the issue! If you want further steps such as load the image you can follow these extra steps:

4. After the image is downloaded, we need a way to load the image bitmap from the internal storage, so we can use it. Let’s write the method for loading the image bitmap. This method takes two paramethers, a context and an image file name, without the full path, the context.openFileInput(imageName) will look up the file at the save directory when this file name was saved in the above saveImage method.

public Bitmap loadImageBitmap(Context context, String imageName) {
    Bitmap bitmap = null;
    FileInputStream fiStream;
    try {
        fiStream    = context.openFileInput(imageName);
        bitmap      = BitmapFactory.decodeStream(fiStream);
        fiStream.close();
    } catch (Exception e) {
        Log.d("saveImage", "Exception 3, Something went wrong!");
        e.printStackTrace();
    }
    return bitmap;
}

5. Now we have everything we needed for setting the image of an ImageView or any other Views that you like to use the image on. When we save the image, we hardcoded the image name as “my_image.jpeg”, now we can pass this image name to the above loadImageBitmap method to get the bitmap and set it to an ImageView.

someImageView.setImageBitmap(loadImageBitmap(getApplicationContext(), "my_image.jpeg"));

6. To get the image full path by image name.

File file            = getApplicationContext().getFileStreamPath("my_image.jpeg");
String imageFullPath = file.getAbsolutePath();

7. Check if the image file exists.

File file =

getApplicationContext().getFileStreamPath("my_image.jpeg");
if (file.exists()) Log.d("file", "my_image.jpeg exists!");

8. To delete the image file.

   File file = getApplicationContext().getFileStreamPath("my_image.jpeg"); if (file.delete()) Log.d("file", "my_image.jpeg deleted!");

Probably the easiest and most secure way in BASH 3 and above is:

var="string    to  split"
read -ra arr <<<"$var"

(where arr is the array which takes the split parts of the string) or, if there might be newlines in the input and you want more than just the first line:

var="string    to  split"
read -ra arr -d '' <<<"$var"

(please note the space in -d ''; it cannot be omitted), but this might give you an unexpected newline from <<<"$var" (as this implicitly adds an LF at the end).

Example:

touch NOPE
var="* a  *"
read -ra arr <<<"$var"
for a in "${arr[@]}"; do echo "[$a]"; done

Outputs the expected

[*]
[a]
[*]

as this solution (in contrast to all previous solutions here) is not prone to unexpected and often uncontrollable shell globbing.

Also this gives you the full power of IFS as you probably want:

Example:

IFS=: read -ra arr < <(grep "^$USER:" /etc/passwd)
for a in "${arr[@]}"; do echo "[$a]"; done

Outputs something like:

[tino]
[x]
[1000]
[1000]
[Valentin Hilbig]
[/home/tino]
[/bin/bash]

As you can see, spaces can be preserved this way, too:

IFS=: read -ra arr <<<' split  :   this    '
for a in "${arr[@]}"; do echo "[$a]"; done

outputs

[ split  ]
[   this    ]

Please note that the handling of IFS in BASH is a subject on its own, so do your tests; some interesting topics on this:

• unset IFS: Ignores runs of SPC, TAB, NL and on line starts and ends
• IFS='': No field separation, just reads everything
• IFS=' ': Runs of SPC (and SPC only)

Some last examples:

var=$'\n\nthis is\n\n\na test\n\n'
IFS=$'\n' read -ra arr -d '' <<<"$var"
i=0; for a in "${arr[@]}"; do let i++; echo "$i [$a]"; done

outputs

1 [this is]
2 [a test]

while

unset IFS
var=$'\n\nthis is\n\n\na test\n\n'
read -ra arr -d '' <<<"$var"
i=0; for a in "${arr[@]}"; do let i++; echo "$i [$a]"; done

outputs

1 [this]
2 [is]
3 [a]
4 [test]

BTW:

• If you are not used to $'ANSI-ESCAPED-STRING' get used to it; it's a timesaver.

• If you do not include -r (like in read -a arr <<<"$var") then read does backslash escapes. This is left as exercise for the reader.

For the second question:

To test for something in a string I usually stick to case, as this can check for multiple cases at once (note: case only executes the first match, if you need fallthrough use multiple case statements), and this need is quite often the case (pun intended):

case "$var" in
'')                empty_var;;                # variable is empty
*' '*)             have_space "$var";;        # have SPC
*[[:space:]]*)     have_whitespace "$var";;   # have whitespaces like TAB
*[^-+.,A-Za-z0-9]*) have_nonalnum "$var";;    # non-alphanum-chars found
*[-+.,]*)          have_punctuation "$var";;  # some punctuation chars found
*)                 default_case "$var";;      # if all above does not match
esac

So you can set the return value to check for SPC like this:

case "$var" in (*' '*) true;; (*) false;; esac

Why case? Because it usually is a bit more readable than regex sequences, and thanks to Shell metacharacters it handles 99% of all needs very well.

waits milliseconds to check if the key is pressed, if pressed in that interval return its ascii value, otherwise it still -1

For a typical XAMPP install on windows you probably have the php_sockets.dll in your C:\xampp\php\ext directory. All you got to do is go to php.ini in the C:\xampp\php directory and change the ;extension=php_sockets.dll to extension=php_sockets.dll.

Here is a fully encapsulated version that doesn't require an external initialization call:

def fn():
    fn.counter=vars(fn).setdefault('counter',-1)
    fn.counter+=1
    print (fn.counter)

In Python, functions are objects and we can simply add, or monkey patch, member variables to them via the special attribute __dict__. The built-in vars() returns the special attribute __dict__.

EDIT: Note, unlike the alternative try:except AttributeError answer, with this approach the variable will always be ready for the code logic following initialization. I think the try:except AttributeError alternative to the following will be less DRY and/or have awkward flow:

def Fibonacci(n):
   if n<2: return n
   Fibonacci.memo=vars(Fibonacci).setdefault('memo',{}) # use static variable to hold a results cache
   return Fibonacci.memo.setdefault(n,Fibonacci(n-1)+Fibonacci(n-2)) # lookup result in cache, if not available then calculate and store it

EDIT2: I only recommend the above approach when the function will be called from multiple locations. If instead the function is only called in one place, it's better to use nonlocal:

def TheOnlyPlaceStaticFunctionIsCalled():
    memo={}
    def Fibonacci(n):
       nonlocal memo  # required in Python3. Python2 can see memo
       if n<2: return n
       return memo.setdefault(n,Fibonacci(n-1)+Fibonacci(n-2))
    ...
    print (Fibonacci(200))
    ...

Well then: welcome to the R world ;-)

            # use curly brackets.
            # 'tryCatch()' will return the last evaluated expression

            # (e.g. warning or error). 
            # You don't need to state the return value via `return()` as code

Additional remarks

tryCatch

tryCatch returns the value associated to executing expr unless there's an error or a warning. In this case, specific return values (see return(NA) above) can be specified by supplying a respective handler function (see arguments error and warning in ?tryCatch). These can be functions that already exist, but you can also define them within tryCatch() (as I did above).

The implications of choosing specific return values of the handler functions

As we've specified that NA should be returned in case of error, the third element in y is NA. If we'd have chosen NULL to be the return value, the length of y would just have been 2 instead of 3 as lapply() will simply "ignore" return values that are NULL. Also note that if you don't specify an explicit return value via return(), the handler functions will return NULL (i.e. in case of an error or a warning condition).

"Undesired" warning message

As warn=FALSE doesn't seem to have any effect, an alternative way to suppress the warning (which in this case isn't really of interest) is to use

suppressWarnings(readLines(con=url))

instead of

readLines(con=url, warn=FALSE)

Multiple expressions

Note that you can also place multiple expressions in the "actual expressions part" (argument expr of tryCatch()) if you wrap them in curly brackets (just like I illustrated in the finally part).

There are some third-party Java libraries that provide string join method, but you probably don't want to start using a library just for something simple like that. I would just create a helper method like this, which I think is a bit better than your version, It uses StringBuffer, which will be more efficient if you need to join many strings, and it works on a collection of any type.

public static <T> String join(Collection<T> values)
{
    StringBuffer ret = new StringBuffer();
    for (T value : values)
    {
        if (ret.length() > 0) ret.append(",");
        ret.append(value);
    }
    return ret.toString();
}

Another suggestion with using Collection.toString() is shorter, but that relies on Collection.toString() returning a string in a very specific format, which I would personally not want to rely on.

Add /usr/local/share/npm/bin/ to your $PATH

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

Python has a weak support for closure. To see what I mean take the following example of a counter using closure with JavaScript:

function initCounter(){
    var x = 0;
    function counter  () {
        x += 1;
        console.log(x);
    };
    return counter;
}

count = initCounter();

count(); //Prints 1
count(); //Prints 2
count(); //Prints 3

Closure is quite elegant since it gives functions written like this the ability to have "internal memory". As of Python 2.7 this is not possible. If you try

def initCounter():
    x = 0;
    def counter ():
        x += 1 ##Error, x not defined
        print x
    return counter

count = initCounter();

count(); ##Error
count();
count();

You'll get an error saying that x is not defined. But how can that be if it has been shown by others that you can print it? This is because of how Python it manages the functions variable scope. While the inner function can read the outer function's variables, it cannot write them.

This is a shame really. But with just read-only closure you can at least implement the function decorator pattern for which Python offers syntactic sugar.

Update

As its been pointed out, there are ways to deal with python's scope limitations and I'll expose some.

1. Use the global keyword (in general not recommended).

2. In Python 3.x, use the nonlocal keyword (suggested by @unutbu and @leewz)

3. Define a simple modifiable class Object

class Object(object):
    pass

and create an Object scope within initCounter to store the variables

def initCounter ():
    scope = Object()
    scope.x = 0
    def counter():
        scope.x += 1
        print scope.x

    return counter

Since scope is really just a reference, actions taken with its fields do not really modify scope itself, so no error arises.

4. An alternative way, as @unutbu pointed out, would be to define each variable as an array (x = [0]) and modify it's first element (x[0] += 1). Again no error arises because x itself is not modified.

5. As suggested by @raxacoricofallapatorius, you could make x a property of counter

def initCounter ():

    def counter():
        counter.x += 1
        print counter.x

    counter.x = 0
    return counter

Something like this will do it:

Rows("12:12").Select
Selection.Delete

So in your code it would look like something like this:

Rows(CStr(rand) & ":" & CStr(rand)).Select
Selection.Delete

https://github.com/networknt/jsontoken

This is a fork of original google jsontoken

It has not been updated since Sep 11, 2012 and depends on some old packages.

What I have done:

Convert from Joda time to Java 8 time. So it requires Java 8.
Covert Json parser from Gson to Jackson as I don't want to include two Json parsers to my projects.
Remove google collections from dependency list as it is stopped long time ago.
Fix thread safe issue with Java Mac.doFinal call.

All existing unit tests passed along with some newly added test cases.

Here is a sample to generate token and verify the token. For more information, please check https://github.com/networknt/light source code for usage.

I am the author of both jsontoken and Omni-Channel Application Framework.

You could use the LINQ select clause and reference the property that relates to your Name column.

I'm using this without any additional settings:

if (!$st->execute()) {
    print_r($st->errorInfo());
}

The CSS grid way

The modern way of doing this (which also avoids having to declare a <div class="row"></div>-wrapper around every two items) would be to make use of a CSS grid. This also gives you easy control on the gaps between your item rows/columns.

.grid-container {_x000D_
  display: grid;_x000D_
  grid-template-columns: repeat(2, 1fr); /* or simply "1fr 1fr;" */_x000D_
  grid-row-gap: 10px; _x000D_
  grid-column-gap: 10px;_x000D_
}_x000D_
_x000D_
.grid-item {_x000D_
  background-color: #f8f8f8;_x000D_
  box-shadow: 0 0 3px #666;_x000D_
  text-align: center;_x000D_
}_x000D_
_x000D_
.grid-item img {_x000D_
  max-width: 100%;_x000D_
}

<div class="grid-container">_x000D_
  <div class="grid-item">1 <br />1.1<br />1.1.1</div>_x000D_
  <div class="grid-item">2</div>_x000D_
  <div class="grid-item">3_x000D_
    <img src="https://lorempixel.com/420/320/abstract/1/Sample" alt="" />_x000D_
    3.1_x000D_
  </div>_x000D_
  <div class="grid-item">4</div>_x000D_
  <div class="grid-item">5 <br />1.1<br />1.1.1</div>_x000D_
  <div class="grid-item">6<img src="https://lorempixel.com/400/300/abstract/" alt="" />_x000D_
    6.1</div>_x000D_
  <div class="grid-item">7</div>_x000D_
  <div class="grid-item">8</div>_x000D_
  <div class="grid-item">9 <br />1.1<br />1.1.1</div>_x000D_
  <div class="grid-item">10</div>_x000D_
  <div class="grid-item">11_x000D_
    <img src="https://lorempixel.com/420/320/abstract/1/Sample" alt="" />_x000D_
    11.1_x000D_
  </div>_x000D_
  <div class="grid-item">12</div>_x000D_
</div>

You can also use printf style of formatting arguments. It is available in at least Chrome, Firefox/Firebug and node.js.

var name = prompt("what is your name?");

console.log("story %s story", name);

It also supports %d for formatting numbers

Add the "extern" keyword to the function definitions in point.h

My experience is that Ionic Pro (https://ionicframework.com/pro) can do the most of the Development and Publish job but you still need Mac or Mac in cloud at these steps:

• create .p12 Certification file
• upload the .ipa file to the App Store

After you created your Certification file, You can upload it to Ionic Pro. You can build .ipa files with proper credentials in cloud. But unfortunately I didn't found another way to upload the .ipa file to App Store, only with Application Loader from Mac.

So I decided to use a pay-as-you-go Mac in cloud account (you pay only for minutes you are logged in) since the time I spend on Mac is very limited (few minutes per App publication).

Use jodatime API

Days.daysBetween(start.toDateMidnight() , end.toDateMidnight() ).getDays() 

where 'start' and 'end' are your DateTime objects. To parse your date Strings into DateTime objects use the parseDateTime method

There is also an android specific JodaTime library.

Just an update to the 'no exceptions on resources' problem as pointed to by @jarmod (do please feel free to update your answer if below seems applicable)

I have tested the below code and it runs fine. It uses 'resources' for doing things, but catches the client.exceptions - although it 'looks' somewhat wrong... it tests good, the exception classes are showing and matching when looked into using debugger at exception time...

It may not be applicable to all resources and clients, but works for data folders (aka s3 buckets).

lab_session = boto3.Session() 
c = lab_session.client('s3') #this client is only for exception catching

try:
    b = s3.Bucket(bucket)
    b.delete()
except c.exceptions.NoSuchBucket as e:
    #ignoring no such bucket exceptions
    logger.debug("Failed deleting bucket. Continuing. {}".format(e))
except Exception as e:
    #logging all the others as warning
    logger.warning("Failed deleting bucket. Continuing. {}".format(e))

Hope this helps...

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

PriceList[0] is a float. PriceList[0][1] is trying to access the first element of a float. Instead, do

PriceList[0] = PriceList[1] = ...code omitted... = PriceList[6] = PizzaChange

or

PriceList[0:7] = [PizzaChange]*7

REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET or POST, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)

With REST, you might instead PUT /profiles/cHao and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.

http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.

Checking in from 2015: We now have native promises in most recent browser (Edge 12, Firefox 40, Chrome 43, Safari 8, Opera 32 and Android browser 4.4.4 and iOS Safari 8.4, but not Internet Explorer, Opera Mini and older versions of Android).

If we want to perform 10 async actions and get notified when they've all finished, we can use the native Promise.all, without any external libraries:

function asyncAction(i) {
    return new Promise(function(resolve, reject) {
        var result = calculateResult();
        if (result.hasError()) {
            return reject(result.error);
        }
        return resolve(result);
    });
}

var promises = [];
for (var i=0; i < 10; i++) {
    promises.push(asyncAction(i));
}

Promise.all(promises).then(function AcceptHandler(results) {
    handleResults(results),
}, function ErrorHandler(error) {
    handleError(error);
});

If you set

-Djava.io.tmpdir=C:\temp

You have to specify the format (fmt) of you data in savetxt, in this case as a string (%s):

num.savetxt('test.txt', DAT, delimiter=" ", fmt="%s") 

The default format is a float, that is the reason it was expecting a float instead of a string and explains the error message.

The selector ".nr:first" is specifically looking for the first, and only the first, element having class "nr" within the selected table element. If you instead call .find(".nr") you will get all of the elements within the table having class "nr". Once you have all of those elements, you could use the .each method to iterate over them. For example:

$(".use-address").click(function() {
    $("#choose-address-table").find(".nr").each(function(i, nrElt) {
        var id = nrElt.text();
        $("#resultas").append("<p>" + id + "</p>"); // Testing: append the contents of the td to a div
    });
});

However, that would get you all of the td.nr elements in the table, not just the one in the row that was clicked. To further limit your selection to the row containing the clicked button, use the .closest method, like so:

$(".use-address").click(function() {
    $(this).closest("tr").find(".nr").each(function(i, nrElt) {
        var id = nrElt.text();
        $("#resultas").append("<p>" + id + "</p>"); // Testing: append the contents of the td to a div
    });
});

  /** POST: add a new hero to the database */
  addHero (hero: Hero): Observable<Hero> {
 return this.http.post<Hero>(this.heroesUrl, hero, httpOptions)
  .pipe(
    catchError(this.handleError('addHero', hero))
  );
}
  /** GET heroes from the server */
 getHeroes (): Observable<Hero[]> {
return this.http.get<Hero[]>(this.heroesUrl)
  .pipe(
    catchError(this.handleError('getHeroes', []))
  );
}

it's because of pipeable/lettable operators which now angular is able to use tree-shakable and remove unused imports and optimize the app

some rxjs functions are changed

do -> tap
catch -> catchError

and Import paths

For JavaScript developers, the general rule is as follows:

rxjs: Creation methods, types, schedulers and utilities

import { Observable, Subject, asapScheduler, pipe, of, from, interval, merge, fromEvent } from 'rxjs';

rxjs/operators: All pipeable operators:

import { map, filter, scan } from 'rxjs/operators';

rxjs/webSocket: The web socket subject implementation

import { webSocket } from 'rxjs/webSocket';

rxjs/ajax: The Rx ajax implementation

import { ajax } from 'rxjs/ajax';

rxjs/testing: The testing utilities

import { TestScheduler } from 'rxjs/testing';

and for backward compatability you can use rxjs-compat

Mark Rushakoff's answer may be simpler, but the following also work and may be more efficient since there is no implicit division operation:

     bool isInteger = (double)((int)f) == f ;

and

     bool isInteger = (decimal)((int)d) == d ;

If you want a single expression for both types, perhaps

     bool isInteger = (double)((int)val) == (double)val ;

In my opinion, the simpler and most elegant way to add a delay in a loop is like this:

names = ['John', 'Ana', 'Mary'];

names.forEach((name, i) => {
 setTimeout(() => {
  console.log(name);
 }, i * 1000);  // one sec interval
});

For apache Ubuntu 2.4.7 , I finally found you need to white list your virtual host in apache2.conf

# access here, or in any related virtual host.
<Directory /home/gav/public_html/>
    Options FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

                    if(grida.lastIndexOf("#", 0) === 0){
                        grida = $(grida);
                    }else{
                        grida = $("#"+grida);
                    }

                    var nm, tmp={}, tmp2={}, tmp3= {}, editable, fr, cv, ind;

                    ind = grida.jqGrid("getInd",rowid,true);
                    if(ind === false) {return success;}
                    editable = $(ind).attr("editable");
                    if (editable==="1") {
                        var cm;
                        var colModel = grida.jqGrid("getGridParam","colModel") ;
                        $("td",ind).each(function(i) {
                            // cm = $('#mygrid').p.colModel[i];
                            cm = colModel[i];
                            nm = cm.name;
                            if ( nm != 'cb' && nm != 'subgrid' && cm.editable===true && nm != 'rn' && !$(this).hasClass('not-editable-cell')) {
                                switch (cm.edittype) {
                                    case "checkbox":
                                        var cbv = ["Yes","No"];
                                        if(cm.editoptions ) {
                                            cbv = cm.editoptions.value.split(":");
                                        }
                                        tmp[nm]=  $("input",this).is(":checked") ? cbv[0] : cbv[1]; 
                                        break;
                                    case 'text':

                                    case "button" :
                                        tmp[nm]=$("input, textarea",this).val();
                                        break;
                                    case 'select':
                                        if(!cm.editoptions.multiple) {

                                            );
                                            tmp2[nm] = selectedText.join(",");

I authored the G2 project, a friendly environment for the command line git lover.
Please get the project from github - G2 https://github.com/orefalo/g2

It has a bunch of handy commands, one of them being exactly what your are looking for: freeze

freeze - Freeze all files in the repository (additions, deletions, modifications) to the staging area, thus staging that content for inclusion in the next commit. Also accept a specific path as parameter

Use LIMIT with two parameters. For example, to return results 11-60 (where result 1 is the first row), use:

SELECT * FROM foo LIMIT 10, 50

For a solution to return all results, see Thomas' answer.

I am joining the choir recommending that you skip the now long outdated classes Date, Calendar, SimpleDateFormat and friends. In particular I would warn against using the deprecated methods and constructors of the Date class, like the Date(String) constructor you used. They were deprecated because they don’t work reliably across time zones, so don’t use them. And yes, most of the constructors and methods of that class are deprecated.

While at the time you asked the question, Joda-Time was (from all I know) a clearly better alternative, time has moved on again. Today Joda-Time is a largely finished project, and its developers recommend you use java.time, the modern Java date and time API, instead. I will show you how.

    ZonedDateTime localTime = ZonedDateTime.now(ZoneId.systemDefault());

    // Convert Local Time to UTC 
    OffsetDateTime gmtTime
            = localTime.toOffsetDateTime().withOffsetSameInstant(ZoneOffset.UTC);
    System.out.println("Local:" + localTime.toString() 
            + " --> UTC time:" + gmtTime.toString());

    // Reverse Convert UTC Time to Local time
    localTime = gmtTime.atZoneSameInstant(ZoneId.systemDefault());
    System.out.println("Local Time " + localTime.toString());

For starters, note that not only is the code only half as long as yours, it is also clearer to read.

On my computer the code prints:

Local:2017-09-02T07:25:46.211+02:00[Europe/Berlin] --> UTC time:2017-09-02T05:25:46.211Z
Local Time 2017-09-02T07:25:46.211+02:00[Europe/Berlin]

I left out the milliseconds from the epoch. You can always get them from System.currentTimeMillis(); as in your question, and they are independent of time zone, so I didn’t find them intersting here.

I hesitatingly kept your variable name localTime. I think it’s a good name. The modern API has a class called LocalTime, so using that name, only not capitalized, for an object that hasn’t got type LocalTime might confuse some (a LocalTime doesn’t hold time zone information, which we need to keep here to be able to make the right conversion; it also only holds the time-of-day, not the date).

Your conversion from local time to UTC was incorrect and impossible

The outdated Date class doesn’t hold any time zone information (you may say that internally it always uses UTC), so there is no such thing as converting a Date from one time zone to another. When I just ran your code on my computer, the first line it printed, was:

Local:Sat Sep 02 07:25:45 CEST 2017,1504329945967 --> UTC time:Sat Sep 02 05:25:45 CEST 2017-1504322745000

07:25:45 CEST is correct, of course. The correct UTC time would have been 05:25:45 UTC, but it says CEST again, which is incorrect.

Now you will never need the Date class again, :-) but if you were ever going to, the must-read would be All about java.util.Date on Jon Skeet’s coding blog.

Question: Can I use the modern API with my Java version?

If using at least Java 6, you can.

• In Java 8 and later the new API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the new classes (that’s ThreeTen for JSR-310, where the modern API was first defined).
• On Android, use the Android edition of ThreeTen Backport. It’s called ThreeTenABP, and I think that there’s a wonderful explanation in this question: How to use ThreeTenABP in Android Project.

Edit 09/2016: In Python 3 and up use urllib.request instead of urllib2

Actually the simplest way is:

import urllib2  # the lib that handles the url stuff

data = urllib2.urlopen(target_url) # it's a file like object and works just like a file
for line in data: # files are iterable
    print line

You don't even need "readlines", as Will suggested. You could even shorten it to: ^*

import urllib2

for line in urllib2.urlopen(target_url):
    print line

But remember in Python, readability matters.

However, this is the simplest way but not the safe way because most of the time with network programming, you don't know if the amount of data to expect will be respected. So you'd generally better read a fixed and reasonable amount of data, something you know to be enough for the data you expect but will prevent your script from been flooded:

import urllib2

data = urllib2.urlopen("http://www.google.com").read(20000) # read only 20 000 chars
data = data.split("\n") # then split it into lines

for line in data:
    print line

^{* Second example in Python 3:}

import urllib.request  # the lib that handles the url stuff

for line in urllib.request.urlopen(target_url):
    print(line.decode('utf-8')) #utf-8 or iso8859-1 or whatever the page encoding scheme is

Key thing is to add the recipients as a list of email ids in your sendmail call.

import smtplib
from email.mime.multipart import MIMEMultipart

me = "[email protected]"
to = "[email protected]"
cc = "[email protected],[email protected]"
bcc = "[email protected],[email protected]"

rcpt = cc.split(",") + bcc.split(",") + [to]
msg = MIMEMultipart('alternative')
msg['Subject'] = "my subject"
msg['To'] = to
msg['Cc'] = cc
msg.attach(my_msg_body)
server = smtplib.SMTP("localhost") # or your smtp server
server.sendmail(me, rcpt, msg.as_string())
server.quit()

The syntax you used is problematic. In html, an attribute (ex: style) has a value delimited by double quotes. In that case, the value of the style attribute is a css list of selectors. Try this:

<h2 style="text-align:center; font-family:tahoma">TITLE</h2>

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Is it "safe" to use $_SERVER['HTTP_HOST'] for all links on a site without having to worry about XSS attacks, even when used in forms?

Yes, it's safe to use $_SERVER['HTTP_HOST'], (and even $_GET and $_POST) as long as you verify them before accepting them. This is what I do for secure production servers:

/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
$reject_request = true;
if(array_key_exists('HTTP_HOST', $_SERVER)){
    $host_name = $_SERVER['HTTP_HOST'];
    // [ need to cater for `host:port` since some "buggy" SAPI(s) have been known to return the port too, see http://goo.gl/bFrbCO
    $strpos = strpos($host_name, ':');
    if($strpos !== false){
        $host_name = substr($host_name, $strpos);
    }
    // ]
    // [ for dynamic verification, replace this chunk with db/file/curl queries
    $reject_request = !array_key_exists($host_name, array(
        'a.com' => null,
        'a.a.com' => null,
        'b.com' => null,
        'b.b.com' => null
    ));
    // ]
}
if($reject_request){
    // log errors
    // display errors (optional)
    exit;
}
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
echo 'Hello World!';
// ...

The advantage of $_SERVER['HTTP_HOST'] is that its behavior is more well-defined than $_SERVER['SERVER_NAME']. Contrast ??:

Contents of the Host: header from the current request, if there is one.

with:

The name of the server host under which the current script is executing.

Using a better defined interface like $_SERVER['HTTP_HOST'] means that more SAPIs will implement it using reliable well-defined behavior. (Unlike the other.) However, it is still totally SAPI dependent ??:

There is no guarantee that every web server will provide any of these [$_SERVER entries]; servers may omit some, or provide others not listed here.

To understand how to properly retrieve the host name, first and foremost you need to understand that a server which contains only code has no means of knowing (pre-requisite for verifying) its own name on the network. It needs to interface with a component that supplies it its own name. This can be done via:

• local config file

• local database

• hardcoded source code

• external request (curl)

• client/attacker's Host: request

• etc

Usually its done via the local (SAPI) config file. Note that you have configured it correctly, e.g. in Apache ??:

A couple of things need to be 'faked' to make the dynamic virtual host look like a normal one.

The most important is the server name which is used by Apache to generate self-referential URLs, etc. It is configured with the ServerName directive, and it is available to CGIs via the SERVER_NAME environment variable.

The actual value used at run time is controlled by the UseCanonicalName setting.

With UseCanonicalName Off the server name comes from the contents of the Host: header in the request. With UseCanonicalName DNS it comes from a reverse DNS lookup of the virtual host's IP address. The former setting is used for name-based dynamic virtual hosting, and the latter is used for** IP-based hosting.

If Apache cannot work out the server name because there is no Host: header or the DNS lookup fails then the value configured with ServerName is used instead.

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

did you already try this ?

$ which virtualenvwrapper.sh

Suggestions:

• Create a File object that refers to the already existing file on disk.
• Use a FileWriter object, and use the constructor that takes the File object and a boolean, the latter if true would allow appending text into the File if it exists.
• Then initialize a PrintWriter passing in the FileWriter into its constructor.
• Then call println(...) on your PrintWriter, writing your new text into the file.
• As always, close your resources (the PrintWriter) when you are done with it.
• As always, don't ignore exceptions but rather catch and handle them.
• The close() of the PrintWriter should be in the try's finally block.

e.g.,

  PrintWriter pw = null;

  try {
     File file = new File("fubars.txt");
     FileWriter fw = new FileWriter(file, true);
     pw = new PrintWriter(fw);
     pw.println("Fubars rule!");
  } catch (IOException e) {
     e.printStackTrace();
  } finally {
     if (pw != null) {
        pw.close();
     }
  }

Easy, no?

echo "<a href='index.php'>Index Page</a>";

if you wanna use html tag like anchor tag you have to put in echo

$this->db->where('(a = 1 or a = 2)');

I solved this problem this way:

1) I run this command:

npm config set strict-ssl false

2) Then set npm to run with http, instead of https:

npm config set registry "http://registry.npmjs.org/"

3) Then install your package

npm install <package name>

No, the structure you found is how Java handles it (that is, with overloading instead of default parameters).

For constructors, See Effective Java: Programming Language Guide's Item 1 tip (Consider static factory methods instead of constructors) if the overloading is getting complicated. For other methods, renaming some cases or using a parameter object can help. This is when you have enough complexity that differentiating is difficult. A definite case is where you have to differentiate using the order of parameters, not just number and type.

A standard way to achieve this would be to use the pkg_resources module which is part of the setuptools package. setuptools is used to create an install-able python package.

You can use pkg_resources to return the contents of your desired file as a string and you can use pkg_resources to get the actual path of the desired file on your system.

Let's say that you have a package called stackoverflow.

stackoverflow/
|-- app
|   `-- __init__.py
`-- resources
    |-- bands
    |   |-- Dream\ Theater
    |   |-- __init__.py
    |   |-- King's\ X
    |   |-- Megadeth
    |   `-- Rush
    `-- __init__.py

3 directories, 7 files

Now let's say that you want to access the file Rush from a module app.run. Use pkg_resources.resouces_filename to get the path to Rush and pkg_resources.resource_string to get the contents of Rush; thusly:

import pkg_resources

if __name__ == "__main__":
    print pkg_resources.resource_filename('resources.bands', 'Rush')
    print pkg_resources.resource_string('resources.bands', 'Rush')

The output:

/home/sri/workspace/stackoverflow/resources/bands/Rush
Base: Geddy Lee
Vocals: Geddy Lee
Guitar: Alex Lifeson
Drums: Neil Peart

This works for all packages in your python path. So if you want to know where lxml.etree exists on your system:

import pkg_resources

if __name__ == "__main__":
    print pkg_resources.resource_filename('lxml', 'etree')

output:

/usr/lib64/python2.7/site-packages/lxml/etree

The point is that you can use this standard method to access files that are installed on your system (e.g pip install xxx or yum -y install python-xxx) and files that are within the module that you're currently working on.

since some minor explanations were missing

Use @Deprecated annotation on the method like this

 /**
 * @param basePrice
 * 
 * @deprecated  reason this method is deprecated <br/>
 *              {will be removed in next version} <br/>
 *              use {@link #setPurchasePrice()} instead like this: 
 * 
 * 
 * <blockquote><pre>
 * getProduct().setPurchasePrice(200) 
 * </pre></blockquote>
 * 
 */
@Deprecated
public void setBaseprice(int basePrice) {
}

remember to explain:

1. Why is this method no longer recommended. What problems arise when using it. Provide a link to the discussion on the matter if any. (remember to separate lines for readability <br/>
2. When it will be removed. (let your users know how much they can still rely on this method if they decide to stick to the old way)
3. Provide a solution or link to the method you recommend {@link #setPurchasePrice()}

There's an Abstract Class Dictionary

http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html

However this requires implementation.

Java gives us a nice implementation called a Hashtable

http://docs.oracle.com/javase/6/docs/api/java/util/Hashtable.html

its very similar with nodejs

var User= require('./Users');

in this case its React:

import User from './User'

right now you can use

return (
      <Users></Users>
    )

I have same problem. I solved install this setup. (I use vs 2015 (4.6))

I faced the same problem once. THe reason for this is that even though the server is available, the config files are missing. You can see the server at Windows -> Show view -> Servers. Their configuration files can be seen at Project Explorer -> Servers. For some reason this second mentioned config files were missing.

I simply deleted the existing server and created a new one with this the config files were also created and the problem was solved!

Similar solution is given at here by Emertana EM java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

Have you tried setting the selection properties of your tableView like this:

tableView.allowsMultipleSelection = NO; tableView.allowsMultipleSelectionDuringEditing = YES; tableView.allowsSelection = NO; tableView.allowsSelectionDuringEditing YES; 

If you want more fine-grain control over when selection is allowed you can override - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath in your UITableView delegate. The documentation states:

Return Value An index-path object that confirms or alters the selected row. Return an NSIndexPath object other than indexPath if you want another cell to be selected. Return nil if you don't want the row selected. 

You can have this method return nil in cases where you don't want the selection to happen.

Not sure if my solution is frowned upon or not, but I use a bound service to persist ViewModel state. Whether you store it in memory in the service or persist and retrieve it from a SQLite database depends on your requirements. This is what services of any flavor do, they provide services such as maintaining application state and abstract common business logic.

Because of memory and processing constraints inherent on mobile devices, I treat Android views in a similar way to a web page. The page does not maintain state, it is purely a presentation layer component whose only purpose is to present application state and accept user input. Recent trends in web app architecture employ the use of the age-old Model, View, Controller (MVC) pattern, where the page is the View, domain data is the model, and the controller sits behind a web service. The same pattern can be employed in Android with the View being, well ... the View, the model is your domain data, and the Controller is implemented as an Android bound service. Whenever you want a view to interact with the controller, bind to it on start/resume and unbind on stop/pause.

This approach gives you the added bonus of enforcing the Separation of Concern design principle in that all of you application business logic can be moved into your service which reduces duplicated logic across multiple views and allows the view to enforce another important design principle, Single Responsibility.

you need to take 2 (hex) chars at the same time... then calculate the int value and after that make the char conversion like...

char d = (char)intValue;

do this for every 2chars in the hex string

this works if the string chars are only 0-9A-F:

#include <stdio.h>
#include <string.h>

int hex_to_int(char c){
        int first = c / 16 - 3;
        int second = c % 16;
        int result = first*10 + second;
        if(result > 9) result--;
        return result;
}

int hex_to_ascii(char c, char d){
        int high = hex_to_int(c) * 16;
        int low = hex_to_int(d);
        return high+low;
}

int main(){
        const char* st = "48656C6C6F3B";
        int length = strlen(st);
        int i;
        char buf = 0;
        for(i = 0; i < length; i++){
                if(i % 2 != 0){
                        printf("%c", hex_to_ascii(buf, st[i]));
                }else{
                        buf = st[i];
                }
        }
}

Should it be name="Id"? Typos are a likely cause.

Next would be to try it out with a non-generic test to make sure you're passing in the proper type parameter.

Can you post the entire error message?

This was too good of an answer not to post it here. It's from a Gilles, a fellow user from askubuntu:

The clipboard is provided by the X server. It doesn't matter whether the server is headless or not, what matters is that your local graphical session is available to programs running on the remote machine. Thanks to X's network-transparent design, this is possible.

I assume that you're connecting to the remote server with SSH from a machine running Linux. Make sure that X11 forwarding is enabled both in the client configuration and in the server configuration. In the client configuration, you need to have the line ForwardX11 yes in ~/.ssh/config to have it on by default, or pass the option -X to the ssh command just for that session. In the server configuration, you need to have the line X11Forwarding yes in /etc/ssh/sshd_config (it is present by default on Ubuntu).

To check whether X11 forwarding is enabled, look at the value of the DISPLAY environment variable: echo $DISPLAY. You should see a value like localhost:10 (applications running on the remote machine are told to connect to a display running on the same machine, but that display connection is in fact forwarded by SSH to your client-side display). Note that if DISPLAY isn't set, it's no use setting it manually: the environment variable is always set correctly if the forwarding is in place. If you need to diagnose SSH connection issues, pass the option -vvv to ssh to get a detailed trace of what's happening.

If you're connecting through some other means, you may or may not be able to achieve X11 forwarding. If your client is running Windows, PuTTY supports X11 forwarding; you'll have to run an X server on the Windows machine such as Xming.

I will provide a detailed differences between Visual Studio and Visual Studio Code below.

If you really look at it the most obvious difference is that .NET has been split into two:

• .NET Core (Mac, Linux, and Windows)
• .NET Framework (Windows only)

All native user interface technologies (Windows Presentation Foundation, Windows Forms, etc.) are part of the framework, not the core.

The "Visual" in Visual Studio (from Visual Basic) was largely synonymous with visual UI (drag & drop WYSIWYG) design, so in that sense, Visual Studio Code is Visual Studio without the Visual!

The second most obvious difference is that Visual Studio tends to be oriented around projects & solutions.

Visual Studio Code:

• It's a lightweight source code editor which can be used to view, edit, run, and debug source code for applications.
• Simply it is Visual Studio without the Visual UI, majorly a superman’s text-editor.
• It is mainly oriented around files, not projects.
• It does not have any scaffolding support.
• It is a competitor of Sublime Text or Atom on Electron.
• It is based on the Electron framework, which is used to build cross platform desktop application using web technologies.
• It does not have support for Microsoft's version control system; Team Foundation Server.
• It has limited IntelliSense for Microsoft file types and similar features.
• It is mainly used by developers on a Mac who deal with client-side technologies (HTML, JavaScript, and CSS).

Visual Studio:

• As the name indicates, it is an IDE, and it contains all the features required for project development. Like code auto completion, debugger, database integration, server setup, configurations, and so on.
• It is a complete solution mostly used by and for .NET related developers. It includes everything from source control to bug tracker to deployment tools, etc. It has everything required to develop.
• It is widely used on .NET related projects (though you can use it for other things). The community version is free, but if you want to make most of it then it is not free.

• Visual Studio is aimed to be the world’s best IDE (integrated development environment), which provide full stack develop toolsets, including a powerful code completion component called IntelliSense, a debugger which can debug both source code and machine code, everything about ASP.NET development, and something about SQL development.

• In the latest version of Visual Studio, you can develop cross-platform application without leaving the IDE. And Visual Studio takes more than 8 GB disk space (according to the components you select).

• In brief, Visual Studio is an ultimate development environment, and it’s quite heavy.

HttpClient lives in the System.Net.Http namespace.

You'll need to add:

using System.Net.Http;

And make sure you are referencing System.Net.Http.dll in .NET 4.5.

The code posted doesn't appear to do anything with webClient. Is there something wrong with the code that is actually compiling using HttpWebRequest?

Update

To open the Add Reference dialog right-click on your project in Solution Explorer and select Add Reference.... It should look something like:

For relative imports see the documentation. A relative import is when you import from a module relative to that module's location, instead of absolutely from sys.path.

As for import *, Python 2 allowed star imports within functions, for instance:

>>> def f():
...     from math import *
...     print sqrt

A warning is issued for this in Python 2 (at least recent versions). In Python 3 it is no longer allowed and you can only do star imports at the top level of a module (not inside functions or classes).

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

You are setting the html of #showresults of whatever data is, and then replacing it with itself, which doesn't make much sense ?
I'm guessing you where really trying to find #showresults in the returned data, and then update the #showresults element in the DOM with the html from the one from the ajax call :

$('#submitform').click(function () {
    $.ajax({
        url: "getinfo.asp",
        data: {
            txtsearch: $('#appendedInputButton').val()
        },
        type: "GET",
        dataType: "html",
        success: function (data) {
            var result = $('<div />').append(data).find('#showresults').html();
            $('#showresults').html(result);
        },
        error: function (xhr, status) {
            alert("Sorry, there was a problem!");
        },
        complete: function (xhr, status) {
            //$('#showresults').slideDown('slow')
        }
    });
});

You can also cast an array to a string like...

newStr = String(aa);

I also agree with Tor Valamo's answer, console.log should have no problem with arrays, no need to convert to a string unless you're debugging something or just curious.

Writing this middleware might help !

This is an old question, but too many examples above are over-complicated.

Keep It Simple: (in Jupyter Notebook or Python 3.7.1 terminal on Windows 10)

import sys
print(sys.executable)```

# example output: >> `C:\Anaconda3\envs\quantecon\python.exe`

OR 
```sys.base_prefix```

# Example output: >> 'C:\\Anaconda3\\envs\\quantecon'

I've create a solution, mixed the information of varius post.

Its a form, that contains a label and one textbox. The console output is redirected to the textbox.

There are too a class called ConsoleView that implements three publics methods: Show(), Close(), and Release(). The last one is for leave open the console and activate the Close button for view results.

The forms is called FrmConsole. Here are the XAML and the c# code.

The use is very simple:

ConsoleView.Show("Title of the Console");

For open the console. Use:

System.Console.WriteLine("The debug message");

For output text to the console.

Use:

ConsoleView.Close();

For Close the console.

ConsoleView.Release();

Leaves open the console and enables the Close button

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

    ' Trying to find the amount of "." in the text
    ' if txtName looks like "hi...hi" then intdots will = 3
    Dim test As String = txtName.Text
    Dim intdots As Integer = 0
    For i = 1 To test.Length
        Dim inta As Integer = 0 + 1
        Dim stra As String = test.Substring(inta)
        If stra = "." Then
            intdots = intdots + 1
        End If
    Next
    txttest.text = intdots

Note that the file:/// scheme does not work on the compact framework, at least it doesn't with 5.0.

You will need to use the following:

string appDir = Path.GetDirectoryName(
    Assembly.GetExecutingAssembly().GetName().CodeBase);
webBrowser1.Url = new Uri(Path.Combine(appDir, @"Documentation\index.html"));

I had the same problem. My JDK package pointed by JAVA_HOME didn't have any tools.jar Be sure that your JDK instal.lation has tools.jar

PdfTextStream (which you said you have been looking at) is now free for single threaded applications. In my opinion its quality is much better than other libraries (esp. for things like funky embedded fonts, etc).

Alternatively, you should have a look at Apache PDFBox, open source.

Because the compiled JavaScript has all the type information erased, you can't use T to new up an object.

You can do this in a non-generic way by passing the type into the constructor.

class TestOne {
    hi() {
        alert('Hi');
    }
}

class TestTwo {
    constructor(private testType) {

    }
    getNew() {
        return new this.testType();
    }
}

var test = new TestTwo(TestOne);

var example = test.getNew();
example.hi();

You could extend this example using generics to tighten up the types:

class TestBase {
    hi() {
        alert('Hi from base');
    }
}

class TestSub extends TestBase {
    hi() {
        alert('Hi from sub');
    }
}

class TestTwo<T extends TestBase> {
    constructor(private testType: new () => T) {
    }

    getNew() : T {
        return new this.testType();
    }
}

//var test = new TestTwo<TestBase>(TestBase);
var test = new TestTwo<TestSub>(TestSub);

var example = test.getNew();
example.hi();

If you created virtual environment using root then use this command

sudo su

it will give you the root access and then activate your virtual environment using this

source /root/.env/ENV_NAME/bin/activate

I personally use Java's naming conventions when developing in other programming languages as it is consistent and easy to follow. That way I am not continuously struggling over what conventions to use which shouldn't be the hardest part of my project!

len(list1)-1 is definitely the way to go, but if you absolutely need a list that has a function that returns the last index, you could create a class that inherits from list.

class MyList(list):
    def last_index(self):
        return len(self)-1


>>> l=MyList([1, 2, 33, 51])
>>> l.last_index()

Both tools are meant to work with text and there are tasks both tools can be used for.

For me the rule to separate them is: Use sed to automate tasks you would do otherwise in a text editor manually. That's why it is called stream editor. (You can use the same commands to edit text in vim). Use awk if you want to analyze text, meaning counting fields, calculate totals, extract and reorganize structures etc.

Also you should not forget about grep. Use grep if you only want to search/extract something in a text (file)

You can use two elements, one inside the other, and give the outer one overflow: hidden and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"

#outer {
    width: 100px;
    overflow: hidden;
    padding-bottom: 10px;
}

#outer > div {
    width: 100px;
    height: 100px;
    background: orange;

    -moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}

Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/

I simply did:

quit();

Please note I'm using mongo 3.0.

Firstly I embed the console application solution into the windows service solution and reference it.

Then I make the console application Program class public

/// <summary>
/// Hybrid service/console application
/// </summary>
public class Program
{
}

I then create two functions within the console application

    /// <summary>
    /// Used to start as a service
    /// </summary>
    public void Start()
    {
        Main();
    }

    /// <summary>
    /// Used to stop the service
    /// </summary>
    public void Stop()
    {
       if (Application.MessageLoop)
            Application.Exit();   //windows app
        else
            Environment.Exit(1);  //console app
    }

Then within the windows service itself I instantiate the Program and call the Start and Stop functions added within the OnStart and OnStop. See below

class WinService : ServiceBase
{
    readonly Program _application = new Program();

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    static void Main()
    {
        ServiceBase[] servicesToRun = { new WinService() };
        Run(servicesToRun);
    }

    /// <summary>
    /// Set things in motion so your service can do its work.
    /// </summary>
    protected override void OnStart(string[] args)
    {
        Thread thread = new Thread(() => _application.Start());
        thread.Start();
    }

    /// <summary>
    /// Stop this service.
    /// </summary>
    protected override void OnStop()
    {
        Thread thread = new Thread(() => _application.Stop());
        thread.Start();
    }
}

This approach can also be used for a windows application / windows service hybrid

You could try this method.

const sortListByRanking = (rankingList, listToSort) => {
  let result = []

  for (let id of rankingList) {
    for (let item of listToSort) {
      if (item && item[1] === id) {
        result.push(item)
      }
    }
  }

  return result
}

Install jupyterlab.

If you get this error:

ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

requests 2.25.1 requires idna<3,>=2.5, but you'll have idna 3.1 which is incompatible.

Use this:

pip3 install jupyterlab --use-feature=2020-resolver

If you just need to know if you can use the foo[123] notation with the variable, you can check for the existence of a __getitem__ attribute (which is what python calls when you access by index) with hasattr(foo, '__getitem__')

Add the following line in your .profile file in your home directory (using vi ~/.profile):

PATH=$PATH:/home/me/play
export PATH

Then, for the change to take effect, simply type in your terminal:

$ . ~/.profile

Another solution is to create a lookup object:

var lookup = {};
for (var i = 0, len = array.length; i < len; i++) {
    lookup[array[i].id] = array[i];
}

... now you can use lookup[id]...

This is especially interesting if you need to do many lookups.

This won't need much more memory since the IDs and objects will be shared.

[ $(echo $variable_to_test | sed s/\n// | sed s/\ //) == "" ] && echo "String is empty"

Stripping all newlines and spaces from the string will cause a blank one to be reduced to nothing which can be tested and acted upon

Further to previous answers its worth noting that:

1. Java allows any Unicode currency symbol in symbol names, so the following will all work:

$var1 £var2 €var3

I believe the usage of currency symbols originates in C/C++, where variables added to your code by the compiler conventionally started with '$'. An obvious example in Java is the names of '.class' files for inner classes, which by convention have the format 'Outer$Inner.class'

2. Many C# and C++ programmers adopt the convention of placing 'I' in front of interfaces (aka pure virtual classes in C++). This is not required, and hence not done, in Java because the implements keyword makes it very clear when something is an interface.

Compare:

class Employee : public IPayable //C++

with

class Employee : IPayable //C#

and

class Employee implements Payable //Java

3. Many projects use the convention of placing an underscore in front of field names, so that they can readily be distinguished from local variables and parameters e.g.

private double _salary;

A tiny minority place the underscore after the field name e.g.

private double salary_;

From a pipe

# This Is a cat
'This', 'Is', 'a', 'cat' | & {"$input"}

# This-Is-a-cat
'This', 'Is', 'a', 'cat' | & {$ofs='-';"$input"}

Write-Host

# This Is a cat
Write-Host 'This', 'Is', 'a', 'cat'

# This-Is-a-cat
Write-Host -Separator '-' 'This', 'Is', 'a', 'cat'

Example

I wish calling SetText were that easy but there are quite a few gotchas that you have to deal with. You have to make sure that the thread you are calling it on is running in the STA. It can sometimes fail with an access denied error then work seconds later without problem - something to do with the COM timing issues in the clipboard. And if your application is accessed over Remote Desktop access to the clipboard is sketchy. We use a centralized method to handle all theses scenarios instead of calling SetText directly.

@Stecy: Here's our centralized code:

The StaHelper class simply executes some arbitrary code on a thread in the Single Thread Apartment (STA) - required by the clipboard.

abstract class StaHelper
{
    readonly ManualResetEvent _complete = new ManualResetEvent( false );    

    public void Go()
    {
        var thread = new Thread( new ThreadStart( DoWork ) )
        {
            IsBackground = true,
        }
        thread.SetApartmentState( ApartmentState.STA );
        thread.Start();
    }

    // Thread entry method
    private void DoWork()
    {
        try
        {
            _complete.Reset();
            Work();
        }
        catch( Exception ex )
        {
            if( DontRetryWorkOnFailed )
                throw;
            else
            {
                try
                {
                    Thread.Sleep( 1000 );
                    Work();
                }
                catch
                {
                    // ex from first exception
                    LogAndShowMessage( ex );
                }
            }
        }
        finally
        {
            _complete.Set();
        }
    }

    public bool DontRetryWorkOnFailed{ get; set; }

    // Implemented in base class to do actual work.
    protected abstract void Work();
}

Then we have a specific class for setting text on the clipboard. Creating a DataObject manually is required in some edge cases on some versions of Windows/.NET. I don't recall the exact scenarios now and it may not be required in .NET 3.5.

class SetClipboardHelper : StaHelper
{
    readonly string _format;
    readonly object _data;

    public SetClipboardHelper( string format, object data )
    {
        _format = format;
        _data = data;
    }

    protected override void Work()
    {
        var obj = new System.Windows.Forms.DataObject(
            _format,
            _data
        );

        Clipboard.SetDataObject( obj, true );
    }
}

Usage looks like this:

new SetClipboardHelper( DataFormats.Text, "See, I'm on the clipboard" ).Go();

If both strings are of the same known locale, you may want to use Intl.Collator object like this:

function equalIgnoreCase(s1: string, s2: string) {
    return new Intl.Collator("en-US", { sensitivity: "base" }).compare(s1, s2) === 0;
}

Obviously, you may want to cache the Collator for better efficiency.

The advantages of this approach is that it should be much faster than using RegExps and is based on an extremely customizable (see description of locales and options constructor parameters in the article above) set of ready-to-use collators.

you can use toggleClass() to toggle class it is really handy.

case:1

<div id='mydiv' class="class1"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class2"></div>

case:2

<div id='mydiv' class="class2"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class1"></div>

case:3

<div id='mydiv' class="class1 class2 class3"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class3"></div>

There are several native solutions I've found while searching the way to check network operator.

For API >=17:

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

// Get information about all radio modules on device board
// and check what you need by calling #getCellIdentity.

final List<CellInfo> allCellInfo = manager.getAllCellInfo();
for (CellInfo cellInfo : allCellInfo) {
    if (cellInfo instanceof CellInfoGsm) {
        CellIdentityGsm cellIdentity = ((CellInfoGsm) cellInfo).getCellIdentity();
        //TODO Use cellIdentity to check MCC/MNC code, for instance.
    } else if (cellInfo instanceof CellInfoWcdma) {
        CellIdentityWcdma cellIdentity = ((CellInfoWcdma) cellInfo).getCellIdentity();
    } else if (cellInfo instanceof CellInfoLte) {
        CellIdentityLte cellIdentity = ((CellInfoLte) cellInfo).getCellIdentity();
    } else if (cellInfo instanceof CellInfoCdma) {
        CellIdentityCdma cellIdentity = ((CellInfoCdma) cellInfo).getCellIdentity();
    } 
}

In AndroidManifest add permission:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
</manifest>

To get network operator you can check mcc and mnc codes:

• https://en.wikipedia.org/wiki/Mobile_country_code (general information).
• https://clients.txtnation.com/hc/en-us/articles/218719768-MCCMNC-mobile-country-code-and-mobile-network-code-list- (quite full and quite latest list of operators).

For API >=22:

final SubscriptionManager subscriptionManager = SubscriptionManager.from(context);
final List<SubscriptionInfo> activeSubscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
for (SubscriptionInfo subscriptionInfo : activeSubscriptionInfoList) {
    final CharSequence carrierName = subscriptionInfo.getCarrierName();
    final CharSequence displayName = subscriptionInfo.getDisplayName();
    final int mcc = subscriptionInfo.getMcc();
    final int mnc = subscriptionInfo.getMnc();
    final String subscriptionInfoNumber = subscriptionInfo.getNumber();
}

For API >=23. To just check if phone is dual/triple/many sim:

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
if (manager.getPhoneCount() == 2) {
    // Dual sim
}

var myVar = $("#start").find('.myClass').first().val();

What about: prop('outerHTML')?

var outerHTML_text = $('#item-to-be-selected').prop('outerHTML');

And to set:

$('#item-to-be-selected').prop('outerHTML', outerHTML_text);

It worked for me.

PS: This is added in jQuery 1.6.

Check out the Arrays.fill methods.

int[] array = new int[4];
Arrays.fill(array, 0);

Search MSDN for "How to: Set Environment Variables for Projects". (It's Project>Properties>Configuration Properties>Debugging "Environment" and "Merge Environment" properties for those who are in a rush.)

The syntax is NAME=VALUE and macros can be used (for example, $(OutDir)).

For example, to prepend C:\Windows\Temp to the PATH:

PATH=C:\WINDOWS\Temp;%PATH%

Similarly, to append $(TargetDir)\DLLS to the PATH:

PATH=%PATH%;$(TargetDir)\DLLS
