Just for completeness and those unaware XSL 1 has choose for multiple conditions.
<xsl:choose>
<xsl:when test="expression">
... some output ...
</xsl:when>
<xsl:when test="another-expression">
... some output ...
</xsl:when>
<xsl:otherwise>
... some output ....
</xsl:otherwise>
</xsl:choose>
Xerces-based tools will emit the following error
The processing instruction target matching "[xX][mM][lL]" is not allowed.
when an XML declaration is encountered anywhere other than at the top of an XML file.
This is a valid diagnostic message; other XML parsers should issue a similar error message in this situation.
Some blank space or other visible content exists before the <?xml ?>
declaration.
Resolution: remove blank space or any other visible content before the XML declaration.
Some invisible content exists before the <?xml ?>
declaration. Most commonly this is a Byte Order Mark
(BOM).
Resolution: Remove the BOM using techniques such as those suggested by the W3C page on the BOM in HTML.
A stray <?xml ?>
declaration exists within the XML content.
This can happen when XML files are combined programmatically or
via cut-and-paste. There can only be one <?xml ?>
declaration
in an XML file, and it can only be at the top.
Resolution: Search for
<?xml
in a case-insensitive manner, and remove all but the top XML
declaration from the file.
Maybe this is a no-brainer for the xslt-professional, but for me at beginner/intermediate level, this got me puzzled. I wanted to do exactly the same thing, but I had to test a responsetime value from an xml instead of a plain number. Following this thread, I tried this:
<xsl:when test="responsetime/@value >= 5000 and responsetime/@value <= 8999">
which generated an error. This works:
<xsl:when test="number(responsetime/@value) >= 5000 and number(responsetime/@value) <= 8999">
Don't really understand why it doesn't work without number(), though. Could it be that without number() the value is treated as a string and you can't compare numbers with a string?
Anyway, hope this saves someone a lot of searching...
You need to put the last()
indexing on the nodelist result, rather than as part of the selection criteria. Try:
(//element[@name='D'])[last()]
You can use the following code when your processor runs on .NET or uses MSXML (as opposed to Java-based or other native processors). It uses msxsl:script
.
Make sure to add the namespace xmlns:msxsl="urn:schemas-microsoft-com:xslt"
to your root xsl:stylesheet
or xsl:transform
element.
In addition, bind outlet
to any namespace you like, for instance xmlns:outlet = "http://my.functions"
.
<msxsl:script implements-prefix="outlet" language="javascript">
function replace_str(str_text,str_replace,str_by)
{
return str_text.replace(str_replace,str_by);
}
</msxsl:script>
<xsl:variable name="newtext" select="outlet:replace_str(string(@oldstring),'me','you')" />
This is more of an xpath question, but like this, assuming the context is the parent element:
<xsl:value-of select="name/@attribute1" />
The other option to try is a straightforward
<img width="100" height="100" src="/root/Image/image.jpeg" class="CalloutRightPhoto"/>
i.e. without {} but instead giving the direct image path
Date functions are available natively, such as:
<xsl:value-of select="current-dateTime()"/>
There is also current-date()
and current-time()
.
Use the EXSLT date and times extension package.
date.xsl
to the location of your XSL files.date.xsl
.For example:
<xsl:stylesheet version="1.0"
xmlns:date="http://exslt.org/dates-and-times"
extension-element-prefixes="date"
...>
<xsl:import href="date.xsl" />
<xsl:template match="//root">
<xsl:value-of select="date:date-time()"/>
</xsl:template>
</xsl:stylesheet>
The problem is that the 'and' is being treated as an 'or'.
No, the problem is that you are using the XPath !=
operator and you aren't aware of its "weird" semantics.
Solution:
Just replace the any x != y
expressions with a not(x = y)
expression.
In your specific case:
Replace:
<xsl:when test="$AccountNumber != '12345' and $Balance != '0'">
with:
<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')">
Explanation:
By definition whenever one of the operands of the !=
operator is a nodeset, then the result of evaluating this operator is true if there is a node in the node-set, whose value isn't equal to the other operand.
So:
$someNodeSet != $someValue
generally doesn't produce the same result as:
not($someNodeSet = $someValue)
The latter (by definition) is true exactly when there isn't a node in $someNodeSet
whose string value is equal to $someValue
.
Lesson to learn:
Never use the !=
operator, unless you are absolutely sure you know what you are doing.
You can use: <xsl:text> </xsl:text>
see the example
<xsl:variable name="module-info">
<xsl:value-of select="@name" /> = <xsl:value-of select="@rev" />
<xsl:text> </xsl:text>
</xsl:variable>
if you write this in file e.g.
<redirect:write file="temp.prop" append="true">
<xsl:value-of select="$module-info" />
</redirect:write>
this variable will produce a new line infile as:
commons-dbcp_commons-dbcp = 1.2.2
junit_junit = 4.4
org.easymock_easymock = 2.4
test="categoryName != ''"
Edit: This covers the most likely interpretation, in my opinion, of "[not] null or empty" as inferred from the question, including it's pseudo-code and my own early experience with XSLT. I.e., "What is the equivalent of the following Java?":
!(categoryName == null || categoryName.equals(""))
For more details e.g., distinctly identifying null vs. empty, see johnvey's answer below and/or the XSLT 'fiddle' I've adapted from that answer, which includes the option in Michael Kay's comment as well as the sixth possible interpretation.
Try inserting <xsl:number format="1. "/><xsl:value-of select="."/><xsl:text>
in the place of ???.
Note the "1. " - this is the number format. More info: here
As Filburt says; but also note that it's usually better to write
test="not(Count = 'N/A')"
If there's exactly one Count element they mean the same thing, but if there's no Count, or if there are several, then the meanings are different.
6 YEARS LATER
Since this answer seems to have become popular, but may be a little cryptic to some readers, let me expand it.
The "=" and "!=" operator in XPath can compare two sets of values. In general, if A and B are sets of values, then "=" returns true if there is any pair of values from A and B that are equal, while "!=" returns true if there is any pair that are unequal.
In the common case where A selects zero-or-one nodes, and B is a constant (say "NA"), this means that not(A = "NA")
returns true if A is either absent, or has a value not equal to "NA". By contrast, A != "NA"
returns true if A is present and not equal to "NA". Usually you want the "absent" case to be treated as "not equal", which means that not(A = "NA")
is the appropriate formulation.
XSLT 1.0 does not have an integer data type, only double. You can use number()
to convert a string to a number.
Patrick is correct, both in the use of the xsl:if
, and in the syntax for checking for the existence of a node. However, as Patrick's response implies, there is no xsl equivalent to if-then-else, so if you are looking for something more like an if-then-else, you're normally better off using xsl:choose
and xsl:otherwise
. So, Patrick's example syntax will work, but this is an alternative:
<xsl:choose>
<xsl:when test="/html/body">body node exists</xsl:when>
<xsl:otherwise>body node missing</xsl:otherwise>
</xsl:choose>
If you need to join xpath-selected text nodes but can not use string-join
(when you are stuck with XSL 1.0) this might help:
<xsl:variable name="x">
<xsl:apply-templates select="..." mode="string-join-mode"/>
</xsl:variable>
joined and normalized: <xsl:value-of select="normalize-space($x)"/>
<xsl:template match="*" mode="string-join-mode">
<xsl:apply-templates mode="string-join-mode"/>
</xsl:template>
<xsl:template match="text()" mode="string-join-mode">
<xsl:value-of select="."/>
</xsl:template>
If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.
At the time of writing, there was a bug in chrome which required an xmlns
attribute in order to trigger rendering:
<xsl:stylesheet xmlns="http://www.w3.org/1999/xhtml" ... >
This was the problem I was running into when serving the xml file from a server.
If unlike me, you are viewing the xml file from a file:///
url, then the solutions mentioning --allow-file-access-from-files
are the ones you want
var formatXml = this.formatXml = function (xml) {
var reg = /(>)(<)(\/*)/g;
var wsexp = / *(.*) +\n/g;
var contexp = /(<.+>)(.+\n)/g;
xml = xml.replace(reg, '$1\n$2$3').replace(wsexp, '$1\n').replace(contexp, '$1\n$2');
var pad = 0;
var formatted = '';
var lines = xml.split('\n');
var indent = 0;
var lastType = 'other';
There are two problems with your xpath - first you need to remove the child selector from after Data
like phihag mentioned. Also you forgot to include root
in your xpath. Here is what you want to do:
select="/root/DataSet/Data[@Value1='2']/@Value2"
In XSLT 1.0 the upper-case()
and lower-case()
functions are not available.
If you're using a 1.0 stylesheet the common method of case conversion is translate()
:
<xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'" />
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />
<xsl:template match="/">
<xsl:value-of select="translate(doc, $lowercase, $uppercase)" />
</xsl:template>
For those interested, there is no:
<xsl:tag-of select="."/>
However you can re-create the tag/element by going:
<xsl:element name="{local-name()}">
<xsl:value-of select="substring(.,1,3)"/>
</xsl:element>
This is useful in an xslt template that for example handles formatting data values for lots of different elements. When you don't know the name of the element being worked on and you can still output the same element, and modify the value if need be.
There is a substring function in XSLT. Example here.
The functionality is indeed similar (apart from the calling semantics, where call-template
requires a name
attribute and a corresponding names template).
However, the parser will not execute the same way.
From MSDN:
Unlike
<xsl:apply-templates>
,<xsl:call-template>
does not change the current node or the current node-list.
You have to reimplement it using <xsl:choose>
tag:
<xsl:choose>
<xsl:when test="$CreatedDate > $IDAppendedDate">
<h2> mooooooooooooo </h2>
</xsl:when>
<xsl:otherwise>
<h2> dooooooooooooo </h2>
</xsl:otherwise>
</xsl:choose>
Try:
//category[@name='Sport' and ./author/text()='James Small']
Here's one way in XSLT 2
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"','''')"/> </xsl:template> </xsl:stylesheet>
Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:variable name="apos">'</xsl:variable> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"',$apos)"/> </xsl:template> </xsl:stylesheet>
This XPath:
count(//Property[long = '11007'])
returns the same value as:
count(//Property/long[text() = '11007'])
...except that the first counts Property
nodes that match the criterion and the second counts long
child nodes that match the criterion.
As per your comment and reading your question a couple of times, I believe that you want to find uniqueness based on a combination of criteria. Therefore, in actuality, I think you are actually checking multiple conditions. The following would work as well:
count(//Property[@Name = 'Alive'][long = '11007'])
because it means the same thing as:
count(//Property[@Name = 'Alive' and long = '11007'])
Of course, you would substitute the values for parameters in your template. The above code only illustrates the point.
EDIT (after question edit)
You were quite right about the XML being horrible. In fact, this is a downright CodingHorror candidate! I had to keep recounting to keep track of the "Property" node I was on presently. I feel your pain!
Here you go:
count(/root/ac/Properties/Property[Properties/Property/Properties/Property/long = $parPropId])
Note that I have removed all the other checks (for ID and Value). They appear not to be required since you are able to arrive at the relevant node using the hierarchy in the XML. Also, you already mentioned that the check for uniqueness is based only on the contents of the long
element.
Found an XML transform stylesheet here (wayback machine link, site itself is in german)
The stylesheet added here could be helpful:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="iso-8859-1"/>
<xsl:strip-space elements="*" />
<xsl:template match="/*/child::*">
<xsl:for-each select="child::*">
<xsl:if test="position() != last()">"<xsl:value-of select="normalize-space(.)"/>", </xsl:if>
<xsl:if test="position() = last()">"<xsl:value-of select="normalize-space(.)"/>"<xsl:text>
</xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Perhaps you want to remove the quotes inside the xsl:if tags so it doesn't put your values into quotes, depending on where you want to use the CSV file.
Three Answers :
Simple :
<img>
<xsl:attribute name="src">
<xsl:value-of select="//your/xquery/path"/>
<xsl:value-of select="'vmLogo.gif'"/>
</xsl:attribute>
</img>
Using 'concat' :
<img>
<xsl:attribute name="src">
<xsl:value-of select="concat(//your/xquery/path,'vmLogo.gif')"/>
</xsl:attribute>
</img>
Attribute shortcut as suggested by @TimC
<img src="{concat(//your/xquery/path,'vmLogo.gif')}" />
For a working doodle/proof of concept of an approach to utilize pure JavaScript along with the familiar and declarative pattern behind XSLT's matching expressions and recursive templates, see https://gist.github.com/brettz9/0e661b3093764f496e36
(A similar approach might be taken for JSON.)
Note that the demo also relies on JavaScript 1.8 expression closures for convenience in expressing templates in Firefox (at least until the ES6 short form for methods may be implemented).
Disclaimer: This is my own code.
One can also do this :
<xsl:text disable-output-escaping="yes"><![CDATA[ ]]></xsl:text>
The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.
To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.
Could I write "table" or any other html tag instead of "/" ?
Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.
Here a few links:
First of all, the provided long code:
<xsl:choose>
<xsl:when test="OU_NAME='OU_ADDR1'"> --comparing two elements coming from XML
<!--remove if adrees already contain operating unit name <xsl:value-of select="OU_NAME"/> <fo:block/>-->
<xsl:if test="OU_ADDR1 !='' ">
<xsl:value-of select="OU_ADDR1"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR2 !='' ">
<xsl:value-of select="OU_ADDR2"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR3 !='' ">
<xsl:value-of select="OU_ADDR3"/>
<fo:block/>
</xsl:if>
<xsl:if test="OU_TOWN_CITY !=''">
<xsl:value-of select="OU_TOWN_CITY"/>,
<fo:leader leader-pattern="space" leader-length="2.0pt"/>
</xsl:if>
<xsl:value-of select="OU_REGION2"/>
<fo:leader leader-pattern="space" leader-length="3.0pt"/>
<xsl:value-of select="OU_POSTALCODE"/>
<fo:block/>
<xsl:value-of select="OU_COUNTRY"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="OU_NAME"/>
<fo:block/>
<xsl:if test="OU_ADDR1 !='' ">
<xsl:value-of select="OU_ADDR1"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR2 !='' ">
<xsl:value-of select="OU_ADDR2"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR3 !='' ">
<xsl:value-of select="OU_ADDR3"/>
<fo:block/>
</xsl:if>
<xsl:if test="OU_TOWN_CITY !=''">
<xsl:value-of select="OU_TOWN_CITY"/>,
<fo:leader leader-pattern="space" leader-length="2.0pt"/>
</xsl:if>
<xsl:value-of select="OU_REGION2"/>
<fo:leader leader-pattern="space" leader-length="3.0pt"/>
<xsl:value-of select="OU_POSTALCODE"/>
<fo:block/>
<xsl:value-of select="OU_COUNTRY"/>
</xsl:otherwise>
</xsl:choose>
is equivalent to this, much shorter code:
<xsl:if test="not(OU_NAME='OU_ADDR1)'">
<xsl:value-of select="OU_NAME"/>
</xsl:if>
<xsl:if test="OU_ADDR1 !='' ">
<xsl:value-of select="OU_ADDR1"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR2 !='' ">
<xsl:value-of select="OU_ADDR2"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR3 !='' ">
<xsl:value-of select="OU_ADDR3"/>
<fo:block/>
</xsl:if>
<xsl:if test="OU_TOWN_CITY !=''">
<xsl:value-of select="OU_TOWN_CITY"/>,
<fo:leader leader-pattern="space" leader-length="2.0pt"/>
</xsl:if>
<xsl:value-of select="OU_REGION2"/>
<fo:leader leader-pattern="space" leader-length="3.0pt"/>
<xsl:value-of select="OU_POSTALCODE"/>
<fo:block/>
<xsl:value-of select="OU_COUNTRY"/>
Now, to your question:
how to compare two elements coming from xml as string
In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator =
and the function not()
together with the operator =
.
$str1 = $str2
evaluates to true()
exactly when the string $str1
is equal to the string $str2
.
not($str1 = $str2)
evaluates to true()
exactly when the string $str1
is not equal to the string $str2
.
There is also the !=
operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.
Now, the rules for comparing two element nodes are similar:
$el1 = $el2
evaluates to true()
exactly when the string value of $el1
is equal to the string value of $el2
.
not($el1 = $el2)
evaluates to true()
exactly when the string value of $el1
is not equal to the string value of $el2
.
However, if one of the operands of =
is a node-set, then
$ns = $str
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string $str
$ns1 = $ns2
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string value of some node from $ns2
Therefore, the expression:
OU_NAME='OU_ADDR1'
evaluates to true()
only when there is at least one element child of the current node that is named OU_NAME
and whose string value is the string 'OU_ADDR1'.
This is obviously not what you want!
Most probably you want:
OU_NAME=OU_ADDR1
This expression evaluates to true
exactly there is at least one OU_NAME
child of the current node and one OU_ADDR1
child of the current node with the same string value.
Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt
, le
, eq
, gt
, ge
and the inherited from XPath 1.0 general comparison operator =
.
Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.
No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:variable name="mapping">
<item key="1" v1="A" v2="B" />
<item key="2" v1="X" v2="Y" />
</xsl:variable>
<xsl:variable name="mappingNode"
select="document('')//xsl:variable[@name = 'mapping']" />
<xsl:template match="....">
<xsl:variable name="testVariable" select="'1'" />
<xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />
<xsl:variable name="variable1" select="$values/@v1" />
<xsl:variable name="variable2" select="$values/@v2" />
</xsl:template>
</xsl:stylesheet>
In fact, once you've got the values
variable, you may not even need separate variable1
and variable2
variables. You could just use $values/@v1
and $values/@v2
instead.
Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:
<xsl:template match="class">
<xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
<xsl:variable name="subexists">
<xsl:choose>
<xsl:when test="joined-subclass">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:variable>
subexists: <xsl:value-of select="$subexists" />
</xsl:template>
And if you need the variable to have "global" scope then declare it outside of the template:
<xsl:variable name="subexists">
<xsl:choose>
<xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:template match="class">
subexists: <xsl:value-of select="$subexists" />
</xsl:template>
Launch chrome like so to bypass this restriction: open -a "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --args --allow-file-access-from-files
.
Derived from Josh Lee's comment but I needed to specify the full path to Google Chrome so as to avoid having Google Chrome opening from my Windows partition (in Parallels).
I found a possible answer here: http://web.archive.org/web/20130329123237/http://www.csharpfriends.com/Articles/getArticle.aspx?articleID=63
From the article:
XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslTransform myXslTrans = new XslTransform() ;
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null) ;
myXslTrans.Transform(myXPathDoc,null,myWriter) ;
Edit:
But my trusty compiler says, XslTransform
is obsolete: Use XslCompiledTransform
instead:
XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslCompiledTransform myXslTrans = new XslCompiledTransform();
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null);
myXslTrans.Transform(myXPathDoc,null,myWriter);
It should be something like...
<xsl:if test="contains($hhref, '1234')">
(not tested)
See w3schools (always a good reference BTW)

I used gTTS package to generate audio from text and then play that audio using Playsound when I was learning webscraping and created a coursera downloader(only free courses).
text2speech = gTTS("Your course " + course_name +

text2speech.save("temp.mp3")

You can't do this with jQuery ajax, but with native XMLHttpRequest.
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){
if (this.readyState == 4 && this.status == 200){
//this.response is what you're looking for
handler(this.response);
console.log(this.response, typeof this.response);
var img = document.getElementById('img');
var url = window.URL || window.webkitURL;
img.src = url.createObjectURL(this.response);
}
}
xhr.open('GET', 'http://jsfiddle.net/img/logo.png');
xhr.responseType = 'blob';
xhr.send();

This can be used in automation scripts if you don't need all tables in all schemas:
for table in $(psql -qAntc '\dt' | cut -d\| -f2); do
...
done
The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.
UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this
???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????
If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this
???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

There are two differences.
First, is in the number of arguments. malloc()
takes a single argument (memory required in bytes), while calloc()
needs two arguments.
Secondly, malloc()
does not initialize the memory allocated, while calloc()
initializes the allocated memory to ZERO.
calloc()
allocates a memory area, the length will be the product of its parameters. calloc
fills the memory with ZERO's and returns a pointer to first byte. If it fails to locate enough space it returns a NULL
pointer.Syntax: ptr_var=(cast_type *)calloc(no_of_blocks , size_of_each_block);
i.e. ptr_var=(type *)calloc(n,s);
malloc()
allocates a single block of memory of REQUSTED SIZE and returns a pointer to first byte. If it fails to locate requsted amount of memory it returns a null pointer.Syntax: ptr_var=(cast_type *)malloc(Size_in_bytes);
The malloc()
function take one argument, which is the number of bytes to allocate, while the calloc()
function takes two arguments, one being the number of elements, and the other being the number of bytes to allocate for each of those elements. Also, calloc()
initializes the allocated space to zeroes, while malloc()
does not.
None of the above worked for me (tomcat 7.0.62)... As Sensei_Shoh notes see the class above the message and add this to logging.properties. My logs were:
Jan 18, 2016 8:44:21 PM org.apache.catalina.startup.TldConfig execute
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
so I added
org.apache.catalina.startup.TldConfig.level = FINE
in conf/logging.properties
After that I got so many "offending" files that I did not bother skipping them (and also reverted to normal logging...)
You can try this as well, it is easy to implement
TimeZone time2 = TimeZone.CurrentTimeZone;
DateTime test = time2.ToUniversalTime(DateTime.Now);
var singapore = TimeZoneInfo.FindSystemTimeZoneById("Singapore Standard Time");
var singaporetime = TimeZoneInfo.ConvertTimeFromUtc(test, singapore);
Change the text to which standard time you want to change.
Use TimeZone
feature of C# to implement.
If you are using Guava, you statically import newArrayList
method from Lists class:
List<String> l = newArrayList(setOfAuthors);
Sounds like you really want a Dictionary<int, string>
or possibly a switch
statement...
You can do it with the conditional operator though:
userType = user.Type == 0 ? "Admin"
: user.Type == 1 ? "User"
: user.Type == 2 ? "Employee"
: "The default you didn't specify";
While you could put that in one line, I'd strongly urge you not to.
I would normally only do this for different conditions though - not just several different possible values, which is better handled in a map.
Use this code in your php script (first lines)
ini_set('allow_url_fopen',1);
Open your cmd (command prompt) and run Python commmands from there. (on Windows go to run or search and type cmd) It should look like this:
python yourprogram.py
This will execute your code in cmd and it will be left open. However to use python command, Python has to be properly installed so cmd recognizes it as a command. Checkout proper installation and variable registration for your OS if this does not happen
set Environment variable ANDROID_DAILY_OVERRIDE to same value Example - b9471da4f76e0d1a88d41a072922b1e0c257745c
this works for me.
In your ajax success callback do this:
success: function(data){
if(data.success == true){ // if true (1)
setTimeout(function(){// wait for 5 secs(2)
location.reload(); // then reload the page.(3)
}, 5000);
}
}
As you want to reload the page after 5 seconds, then you need to have a timeout as suggested in the answer.
You likely don't have a CA signed certificate installed in your SQL VM's trusted root store.
If you have Encrypt=True
in the connection string, either set that to off (not recommended), or add the following in the connection string:
TrustServerCertificate=True
SQL Server will create a self-signed certificate if you don't install one for it to use, but it won't be trusted by the caller since it's not CA-signed, unless you tell the connection string to trust any server cert by default.
Long term, I'd recommend leveraging Let's Encrypt to get a CA signed certificate from a known trusted CA for free, and install it on the VM. Don't forget to set it up to automatically refresh. You can read more on this topic in SQL Server books online under the topic of "Encryption Hierarchy", and "Using Encryption Without Validation".
You use something like
from flask import send_file
@app.route('/get_image')
def get_image():
if request.args.get('type') == '1':
filename = 'ok.gif'
else:
filename = 'error.gif'
return send_file(filename, mimetype='image/gif')
to send back ok.gif
or error.gif
, depending on the type query parameter. See the documentation for the send_file
function and the request
object for more information.
If you're using Webpack:
webpack.config.js:
plugins: [
<... your plugins here>,
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery",
"window.Tether": 'tether'
})
]
The checking of the presence of the member before assigning it is, in my opinion, quite ugly.
Kohana has a useful function to make selecting parameters simple.
You can make your own like so...
function arrayGet($array, $key, $default = NULL)
{
return isset($array[$key]) ? $array[$key] : $default;
}
And then do something like...
$page = arrayGet($_GET, 'p', 1);
You can use:
Bulk collect along with FOR ALL that is called Bulk binding
.
Because PL/SQL forall
operator speeds 30x faster for simple table inserts.
BULK_COLLECT
and Oracle FORALL
together these two features are known as Bulk Binding
. Bulk Binds are a PL/SQL technique where, instead of multiple individual SELECT
, INSERT
, UPDATE
or DELETE
statements are executed to retrieve from, or store data in, at table, all of the operations are carried out at once, in bulk. This avoids the context-switching you get when the PL/SQL engine has to pass over to the SQL engine, then back to the PL/SQL engine, and so on, when you individually access rows one at a time. To do bulk binds with INSERT
, UPDATE
, and DELETE
statements, you enclose the SQL statement within a PL/SQL FORALL
statement. To do bulk binds with SELECT
statements, you include the BULK COLLECT
clause in the SELECT
statement instead of using INTO
.
It improves performance.
These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".
The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.
ffmpeg
vs the fake oneFor a while both Libav and FFmpeg separately developed their own version of ffmpeg
.
Libav then renamed their bizarro ffmpeg
to avconv
to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv
instead of their counterfeit version of ffmpeg
. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.
This message was removed upstream when the fake "ffmpeg
" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.
In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1
. Unfortunately the new "deprecated" message has caused additional user confusion.
Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg
is back in the repositories again.
To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.
If you are using avconv
then you are using Libav. If you are using ffmpeg
you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.
Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h
header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg
or avconv
and viewing the console output.
ffmpeg
The real ffmpeg
is in the repository, so you can install it with:
apt-get install ffmpeg
Your options are:
ffmpeg
,ffmpeg
,These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.
Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg
from the repository.
For an interesting blog article on the situation, as well as a discussion about the main technical differences between the projects, see The FFmpeg/Libav situation.

i had this similar problem. I'm using SpringBoot 2.4.1
. If you face similar problem i.e. cannot load yml
files, try adding this class-level annotation in your test.
@SpringJUnitConfig(
classes = { UserAccountPropertiesTest.TestConfig.class },
initializers = { ConfigDataApplicationContextInitializer.class }
)
class UserAccountPropertiesTest {
@Configuration
@EnableConfigurationProperties(UserAccountProperties.class)
static class TestConfig { }
@Autowired
UserAccountProperties userAccountProperties;
@Test
void getAccessTokenExpireIn() {
assertThat(userAccountProperties.getAccessTokenExpireIn()).isEqualTo(120);
}
@Test
void getRefreshTokenExpireIn() {
assertThat(userAccountProperties.getRefreshTokenExpireIn()).isEqualTo(604800);
}
}
the ConfigDataApplicationContextInitializer
from import org.springframework.boot.test.context.ConfigDataApplicationContextInitializer;
is the one that "help" translate the yml
files i think.
I'm able to run my test successfully.
Or, if you're customizing the dialog using a theme defined in your style xml, put this line in your theme:
<item name="android:windowCloseOnTouchOutside">true</item>
Try this:
select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;
I just discovered the Hmisc package:
Contains many functions useful for data analysis, high-level graphics, utility operations, functions for computing sample size and power, importing and annotating datasets, imputing missing values, advanced table making, variable clustering, character string manipulation, conversion of R objects to LaTeX and html code, and recoding variables.
library(Hmisc)
plot(...)
minor.tick(nx=10, ny=10) # make minor tick marks (without labels) every 10th
SELECT name, create_date, modify_date
FROM sys.objects
WHERE type = 'P'
ORDER BY modify_date DESC
The type
for a function is FN
rather than P
for procedure. Or you can filter on the name column.
Some might encounter this error (I got it while implementing PHP-MySQLi-JSON-Google Chart Example):
You called the draw() method with the wrong type of data rather than a DataTable or DataView.
The solution would be: replace jsapi and just use loader.js with:
google.charts.load('current', {packages: ['corechart']}) and
google.charts.setOnLoadCallback
-- according to the release notes --> The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader from now on.
Python
As @numeral correctly said, column._jc.toString()
works fine in case of unaliased columns.
In case of aliased columns (i.e. column.alias("whatever")
) the alias can be extracted, even without the usage of regular expressions: str(column).split(" AS ")[1].split("`")[1]
.
I don't know Scala syntax, but I'm sure It can be done the same.
numpy.linspace()
gives you a one-dimensional NumPy array. For example:
>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([ 1., 2., 3., 4., 5., 6., 7., 8., 9., 10.])
Therefore:
for index,point in my_array
cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:
>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])
Now you can do this:
>>> for x, y in two_d:
print(x, y)
1 2
4 5
I'm successfully using the following to update options dynamically:
$control.select2('destroy').empty().select2({data: [{id: 1, text: 'new text'}]});
Use a for
loop instead of .forEach()
var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false
for(var call of myObj) {
console.log(call)
var a = call['a'], b = call['b']
if(a == null || b == null) {
result = false
break
}
}
In my case I was needed update the std=c++
I mean in my gradle file was this
android {
...
defaultConfig {
...
externalNativeBuild {
cmake {
cppFlags "-std=c++11", "-Wall"
arguments "-DANDROID_STL=c++_static",
"-DARCORE_LIBPATH=${arcore_libpath}/jni",
"-DARCORE_INCLUDE=${project.rootDir}/app/src/main/libs"
}
}
....
}
I changed this line
android {
...
defaultConfig {
...
externalNativeBuild {
cmake {
cppFlags "-std=c++17", "-Wall" <-- this number from 11 to 17 (or 14)
arguments "-DANDROID_STL=c++_static",
"-DARCORE_LIBPATH=${arcore_libpath}/jni",
"-DARCORE_INCLUDE=${project.rootDir}/app/src/main/libs"
}
}
....
}
That's it...
Having the following XML:
<node>Text1<subnode/>text2</node>
How do I select either the first or the second text node via XPath?
Use:
/node/text()
This selects all text-node children of the top element (named "node") of the XML document.
/node/text()[1]
This selects the first text-node child of the top element (named "node") of the XML document.
/node/text()[2]
This selects the second text-node child of the top element (named "node") of the XML document.
/node/text()[someInteger]
This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:
/node/text()[position() = someInteger]
Since the previous answers were written, requests have changed. Have a look at the bug thread at Github for more detail and this comment for an example.
In short, the files parameter takes a dict
with the key being the name of the form field and the value being either a string or a 2, 3 or 4-length tuple, as described in the section POST a Multipart-Encoded File in the requests quickstart:
>>> url = 'http://httpbin.org/post'
>>> files = {'file': ('report.xls', open('report.xls', 'rb'), 'application/vnd.ms-excel', {'Expires': '0'})}
In the above, the tuple is composed as follows:
(filename, data, content_type, headers)
If the value is just a string, the filename will be the same as the key, as in the following:
>>> files = {'obvius_session_id': '72c2b6f406cdabd578c5fd7598557c52'}
Content-Disposition: form-data; name="obvius_session_id"; filename="obvius_session_id"
Content-Type: application/octet-stream
72c2b6f406cdabd578c5fd7598557c52
If the value is a tuple and the first entry is None
the filename property will not be included:
>>> files = {'obvius_session_id': (None, '72c2b6f406cdabd578c5fd7598557c52')}
Content-Disposition: form-data; name="obvius_session_id"
Content-Type: application/octet-stream
72c2b6f406cdabd578c5fd7598557c52
This would be easier to do with flexbox. Using flexbox will let you not to specify the height of your content and can adjust automatically on the height it contains.
here's the gist of the demo
.container{
display: flex;
height: 100%;
justify-content: center;
align-items: center;
}
html
<div class="container">
<div class='content'> //you can size this anyway you want
put anything you want here,
</div>
</div>
The Pattern.quote(String s)
sort of does what you want. However it leaves a little left to be desired; it doesn't actually escape the individual characters, just wraps the string with \Q...\E
.
There is not a method that does exactly what you are looking for, but the good news is that it is actually fairly simple to escape all of the special characters in a Java regular expression:
regex.replaceAll("[\\W]", "\\\\$0")
Why does this work? Well, the documentation for Pattern
specifically says that its permissible to escape non-alphabetic characters that don't necessarily have to be escaped:
It is an error to use a backslash prior to any alphabetic character that does not denote an escaped construct; these are reserved for future extensions to the regular-expression language. A backslash may be used prior to a non-alphabetic character regardless of whether that character is part of an unescaped construct.
For example, ;
is not a special character in a regular expression. However, if you escape it, Pattern
will still interpret \;
as ;
. Here are a few more examples:
>
becomes \>
which is equivalent to >
[
becomes \[
which is the escaped form of [
8
is still 8
.\)
becomes \\\)
which is the escaped forms of \
and (
concatenated. Note: The key is is the definition of "non-alphabetic", which in the documentation really means "non-word" characters, or characters outside the character set [a-zA-Z_0-9]
.
Here is some one liner xpath 1.0 expressions for IndexOf( $text, $searchString ):
If you need the position of the FIRST character of the sought string, or 0 if it is not present:
contains($text,$searchString)*(1 + string-length(substring-before($text,$searchString)))
If you need the position of the first character AFTER the found string, or 0 if it is not present:
contains($text,$searchString)*(1 + string-length(substring-before($text,$searchString)) + string-length($searchString))
Alternatively if you need the position of the first character AFTER the found string, or length+1 if it is not present:
1 + string-length($right) - string-length(substring-after($right,$searchString))
That should cover most cases that you need.
Note: The multiplication by contains( ... ) causes the true or false result of the contains( ... ) function to be converted to 1 or 0, which elegantly provides the "0 when not found" part of the logic.
a Helper function:
private void setRegionBorderWithMedium(CellRangeAddress region, Sheet sheet) {
Workbook wb = sheet.getWorkbook();
RegionUtil.setBorderBottom(CellStyle.BORDER_MEDIUM, region, sheet, wb);
RegionUtil.setBorderLeft(CellStyle.BORDER_MEDIUM, region, sheet, wb);
RegionUtil.setBorderRight(CellStyle.BORDER_MEDIUM, region, sheet, wb);
RegionUtil.setBorderTop(CellStyle.BORDER_MEDIUM, region, sheet, wb);
}
When you want to add Border in Excel, then
String cellAddr="$A$11:$A$17";
setRegionBorderWithMedium(CellRangeAddress.valueOf(cellAddr1), sheet);
A few snippets from the HTML5 spec: http://w3c.github.io/html/semantics-scripting.html#element-attrdef-script-async
The defer and async attributes must not be specified if the src attribute is not present.
There are three possible modes that can be selected using these attributes [async and defer]. If the async attribute is present, then the script will be executed asynchronously, as soon as it is available. If the async attribute is not present but the defer attribute is present, then the script is executed when the page has finished parsing. If neither attribute is present, then the script is fetched and executed immediately, before the user agent continues parsing the page.
The exact processing details for these attributes are, for mostly historical reasons, somewhat non-trivial, involving a number of aspects of HTML. The implementation requirements are therefore by necessity scattered throughout the specification. The algorithms below (in this section) describe the core of this processing, but these algorithms reference and are referenced by the parsing rules for script start and end tags in HTML, in foreign content, and in XML, the rules for the document.write() method, the handling of scripting, etc.
If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute:
The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.
In Boto3, if you're checking for either a folder (prefix) or a file using list_objects. You can use the existence of 'Contents' in the response dict as a check for whether the object exists. It's another way to avoid the try/except catches as @EvilPuppetMaster suggests
import boto3
client = boto3.client('s3')
results = client.list_objects(Bucket='my-bucket', Prefix='dootdoot.jpg')
return 'Contents' in results
You can use .map
: http://jsfiddle.net/9ndcL/1/.
// array of text of each td
var texts = $("td").map(function() {
return $(this).text();
});
vector<T>::const_iterator first = myVec.begin() + 100000;
vector<T>::const_iterator last = myVec.begin() + 101000;
vector<T> newVec(first, last);
It's an O(N) operation to construct the new vector, but there isn't really a better way.
In most of the modern single page applications, we indeed have to store the token somewhere on the client side (most common use case - to keep the user logged in after a page refresh).
There are a total of 2 options available: Web Storage (session storage, local storage) and a client side cookie. Both options are widely used, but this doesn't mean they are very secure.
Tom Abbott summarizes well the JWT sessionStorage and localStorage security:
Web Storage (localStorage/sessionStorage) is accessible through JavaScript on the same domain. This means that any JavaScript running on your site will have access to web storage, and because of this can be vulnerable to cross-site scripting (XSS) attacks. XSS, in a nutshell, is a type of vulnerability where an attacker can inject JavaScript that will run on your page. Basic XSS attacks attempt to inject JavaScript through form inputs, where the attacker puts
<script>alert('You are Hacked');</script>
into a form to see if it is run by the browser and can be viewed by other users.
To prevent XSS, the common response is to escape and encode all untrusted data. React (mostly) does that for you! Here's a great discussion about how much XSS vulnerability protection is React responsible for.
But that doesn't cover all possible vulnerabilities! Another potential threat is the usage of JavaScript hosted on CDNs or outside infrastructure.
Here's Tom again:
Modern web apps include 3rd party JavaScript libraries for A/B testing, funnel/market analysis, and ads. We use package managers like Bower to import other peoples’ code into our apps.
What if only one of the scripts you use is compromised? Malicious JavaScript can be embedded on the page, and Web Storage is compromised. These types of XSS attacks can get everyone’s Web Storage that visits your site, without their knowledge. This is probably why a bunch of organizations advise not to store anything of value or trust any information in web storage. This includes session identifiers and tokens.
Therefore, my conclusion is that as a storage mechanism, Web Storage does not enforce any secure standards during transfer. Whoever reads Web Storage and uses it must do their due diligence to ensure they always send the JWT over HTTPS and never HTTP.
If you need a more specific text alignment than what adding spaces to the left of the text provides, you can always add a second blank label of exactly how much of an indent you need.
I've got buttons with text aligned left with an indent of 10px and needed a label below to look in line. It gave the label with text and left alignment and put it at x=10 and then made a small second label of the same background color with a width = 10, and lined it up next to the real label.
Minimal code and looks good. Just makes AutoLayout a little more of a hassle to get everything working.
foreach (GridViewRow gvr in gvMyGridView.Rows)
{
string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}
You can use this code while doing an iteration with foreach
or for any GridView event like OnRowDataBound
.
Here you can input multiple values for DataKeyNames
by separating with comma ,
. For example, DataKeyNames="ProductID,ItemID,OrderID"
.
You can now access each of DataKeys
by providing its index like below:
string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();
You can also use Key Name instead of its index to get the values from DataKeyNames
collection like below:
string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();
Use the retainAll()
method of Set
:
Set<String> s1;
Set<String> s2;
s1.retainAll(s2); // s1 now contains only elements in both sets
If you want to preserve the sets, create a new set to hold the intersection:
Set<String> intersection = new HashSet<String>(s1); // use the copy constructor
intersection.retainAll(s2);
The javadoc of retainAll()
says it's exactly what you want:
Retains only the elements in this set that are contained in the specified collection (optional operation). In other words, removes from this set all of its elements that are not contained in the specified collection. If the specified collection is also a set, this operation effectively modifies this set so that its value is the intersection of the two sets.

Another way to ensure you get the correct url regardless of server settings is to put the url into a hidden field on your page and reference it for the path:
<input type="hidden" id="GetIndexDataPath" value="@Url.Action("Index","Home")" />
Then you just get the value in your ajax call:
var path = $("#GetIndexDataPath").val();
$.ajax({
type: "GET",
url: path,
data: { id = e.value},
dataType: "html",
success : function (data) {
$('div#theNewView').html(data);
}
});
}
I have been using this for years to cope with server weirdness, as it always builds the correct url. It also makes keeping track of changing controller method calls a breeze if you put all the hidden fields together in one part of the html or make a separate razor partial to hold them.
I know I'm a bit late for that one, but I'll share what I did too, in case it helps someone else :
HashMap<String, HashMap> selects = new HashMap<String, HashMap>();
for(Map.Entry<String, HashMap> entry : selects.entrySet()) {
String key = entry.getKey();
HashMap value = entry.getValue();
// do what you have to do here
// In your case, another loop.
}
This is a little late answer, but I found this awesome post about NgModelController
, which I think is exactly what you were looking for.
TL;DR - you can use require: 'ngModel'
and then add NgModelController
to your linking function:
link: function(scope, iElement, iAttrs, ngModelCtrl) {
//TODO
}
This way, no hacks needed - you are using Angular's built-in ng-model
var str = "The rain in SPAIN stays mainly in the plain";
function searchIndex(str, searchValue, isCaseSensitive) {
var modifiers = isCaseSensitive ? 'gi' : 'g';
var regExpValue = new RegExp(searchValue, modifiers);
var matches = [];
var startIndex = 0;
var arr = str.match(regExpValue);
[].forEach.call(arr, function(element) {
startIndex = str.indexOf(element, startIndex);
matches.push(startIndex++);
});
return matches;
}
console.log(searchIndex(str, 'ain', true));
it's easy to rewrite this code in C#...
This method works if your value it's between 2 substrings !
for example:
stringContent = "[myName]Alex[myName][color]red[color][etc]etc[etc]"
calls should be:
myNameValue = SplitStringByASubstring(stringContent , "[myName]")
colorValue = SplitStringByASubstring(stringContent , "[color]")
etcValue = SplitStringByASubstring(stringContent , "[etc]")
I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between
BEGIN
SELECT MONTH(CURDATE()) INTO @curmonth;
SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
SELECT DAY(@checkweekday) INTO @checkday;
SET @daycount = 0;
SET @workdays = 0;
WHILE(@daycount < @totaldays) DO
IF (WEEKDAY(@checkweekday) < 5) THEN
SET @workdays = @workdays+1;
END IF;
SET @daycount = @daycount+1;
SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
END WHILE;
END
Just for others:
If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query
delimiter ;;
drop procedure if exists test2;;
create procedure test2()
begin
select ‘Hello World’;
end
;;
Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.
The first_day function you need is: How to get first day of every corresponding month in mysql?
Showing the Procedure is working Simply add the following line below END WHILE and above END
SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;
Then use the following code in the SQL Query Window.
call test2 /* or whatever you changed the name of the stored procedure to */
NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).
Hi this is due to new version of the jQuery => 1.9.0
you can check the update : http://blog.jquery.com/2013/01/15/jquery-1-9-final-jquery-2-0-beta-migrate-final-released/
jQuery.Browser is deprecated. you can keep latest version by adding a migration script : http://code.jquery.com/jquery-migrate-1.0.0.js
replace :
<script src="http://code.jquery.com/jquery-latest.js"></script>
by :
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.0.0.js"></script>
in your page and its working.
The post needs an update after the links
option is deprecated.
Basically, links
is no longer needed because its main purpose, making container reachable by another by adding environment variable, is included implicitly with network
. When containers are placed in the same network, they are reachable by each other using their container name and other alias as host.
For docker run
, --link
is also deprecated and should be replaced by a custom network.
docker network create mynet
docker run -d --net mynet --name container1 my_image
docker run -it --net mynet --name container1 another_image
depends_on
expresses start order (and implicitly image pulling order), which was a good side effect of links
.
<input type="checkbox" id="ans" value="1" />
Jquery :
var test= $("#ans").is(':checked')
and it return true or false.
In your function:
$test =($request->get ( 'test' )== "true")? '1' : '0';
You should declare it with declarations array(meta property) of @NgModule
as shown below (RC5 and later
),
import {CoursesComponent} from './courses.component';
@NgModule({
imports: [ BrowserModule],
declarations: [ AppComponent,CoursesComponent], //<----here
providers: [],
bootstrap: [ AppComponent ]
})
I use MongoVUE, it's good for viewing data, but there is almost no editing abilities.
char str[]= "Hello\0";
That would be 7 bytes.
In memory it'd be:
48 65 6C 6C 6F 00 00
H e l l o \0 \0
Edit:
What does the \0 symbol mean in a C string?
It's the "end" of a string. A null character. In memory, it's actually a Zero. Usually functions that handle char arrays look for this character, as this is the end of the message. I'll put an example at the end.
What is the length of str array? (Answered before the edit part)
7
and with how much 0s it is ending?
You array has two "spaces" with zero; str[5]=str[6]='\0'=0
Extra example:
Let's assume you have a function that prints the content of that text array.
You could define it as:
char str[40];
Now, you could change the content of that array (I won't get into details on how to), so that it contains the message: "This is just a printing test" In memory, you should have something like:
54 68 69 73 20 69 73 20 6a 75 73 74 20 61 20 70 72 69 6e 74
69 6e 67 20 74 65 73 74 00 00 00 00 00 00 00 00 00 00 00 00
So you print that char array. And then you want a new message. Let's say just "Hello"
48 65 6c 6c 6f 00 73 20 6a 75 73 74 20 61 20 70 72 69 6e 74
69 6e 67 20 74 65 73 74 00 00 00 00 00 00 00 00 00 00 00 00
Notice the 00 on str[5]. That's how the print function will know how much it actually needs to send, despite the actual longitude of the vector and the whole content.
You can remove the 404 by removing the line
//@ sourceMappingURL=jquery-1.10.2.min.map
from the top part of your jQuery file.
The top part of the jQuery file will look like this.
/*! jQuery v1.10.2 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license
//@ sourceMappingURL=jquery-1.10.2.min.map
*/
Just change that to
/*! jQuery v1.10.2 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license */
Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location. Developer tools (currently WebKit nightly builds, Google Chrome, or Firefox 23+) can parse the source map automatically and make it appear as though you're running unminified and uncombined files. (Read more on this here)
They aren't the same though, are they? One is a copy, the other is a swap. Hence the function names.
My favourite is:
a = b;
Where a
and b
are vectors.
The delimiter can be a regular expression.
awk -F'[/=]' '{print $3 "\t" $5 "\t" $8}' file
Produces:
tc0001 tomcat7.1 demo.example.com
tc0001 tomcat7.2 quest.example.com

I had the same problem with selenium 2 in internet explorer 9, but my fix is really strange. I was not able to click into inputs inside my form -> selenium repeats, their are not visible.
It occured when my form had curved shadows -> http://www.paulund.co.uk/creating-different-css3-box-shadows-effects: in the concrete "Effect no. 2"
I have no idea, why&how this pseudo element solution's stopped selenium tests, but it works for me.
I think it is better to use Array.Exists than Array.FindAll.
As far as I can tell there is no upper limit in 2008.
In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg
variable with
Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.
the code below fails with
REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.
However it appears these limitations have quietly been lifted. On 2008
DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681);
SET @y = REPLICATE(@y,92681);
SELECT LEN(@y)
Returns
8589767761
I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory
Running
select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid
Returned
internal_objects_alloc_page_co
------------------------------
2144456
so I presume this all just gets stored in LOB
pages in tempdb
with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681);
statement. The initial variable assignment to @y
and the LEN
calculation did not increase this.
The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE
method isn't supported for varchar(max) variables.
Addition
I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max)
and nvarchar(max) + varchar(max)
. Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes.
again. The script for that is below (may take a long time to run).
DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647);
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1) /*4294967294, 4294967292*/
DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823);
SET @y2 = @y2 + @y2;
SELECT LEN(@y2), DATALENGTH(@y2) /*2147483646, 4294967292*/
DECLARE @y3 NVARCHAR(MAX) = @y2 + @y1
SELECT LEN(@y3), DATALENGTH(@y3) /*6442450940, 12884901880*/
/*This attempt fails*/
SELECT @y1 y1, @y2 y2, @y3 y3

Here is how to do it properly:
$em->createQuery(“SELECT users

The method setParameters
will take the given array and implode it properly to be used in the “IN” statement.
ZXing is an open source project that can detect and parse a number of different barcodes. It can also generate QR-codes. (Only QR-codes, though).
There are a number of variants for different languages: ActionScript, Android (java), C++, C#, IPhone (Obj C), Java ME, Java SE, JRuby, JSP. Support for generating QR-codes comes with some of those: ActionScript, Android, C# and the Java variants.
I finally figured out, it's because the Hibernate is using slf4j log facade now, to bridge to log4j, you need to put log4j and slf4j-log4j12 jars to your lib and then the log4j properties will take control Hibernate logs.
My pom.xml setting looks as below:
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.16</version>

<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>

Atom is open source (has been for a few hours by now), whereas Sublime Text is not.
Happens when you try to use a variable that wasn't previously defined.
A typical example would be
foreach ($items as $item) {
// do something with item
$counter++;
}
If you didn't define $counter
before, the code above will trigger the notice.
The correct way would be to set the variable before using it, even if it's just an empty string like
$counter = 0;
foreach ($items as $item) {
// do something with item
$counter++;
}
Similarly, a variable is not accessible outside its scope, for example when using anonymous functions.
$prefix = "Blueberry";
$food = ["cake", "cheese", "pie"];
$prefixedFood = array_map(function ($food) {
// Prefix is undefined
return "${prefix} ${food}";
}, $food);
This should instead be passed using use
$prefix = "Blueberry";
$food = ["cake", "cheese", "pie"];
$prefixedFood = array_map(function ($food) use ($prefix) {
return "${prefix} ${food}";
}, $food);
This error means much the same thing, but refers to a property of an object. Reusing the example above, this code would trigger the error because the counter
property hasn't been set.
$obj = new stdclass;
$obj->property = 2342;
foreach ($items as $item) {
// do something with item
$obj->counter++;
}

esModuleInterop
generates the helpers outlined in the docs. Looking at the generated code, we can see exactly what these do:
//ts
import React from 'react'
//js
var __importDefault = (this && this.__importDefault) || function (mod) {
return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
var react_1 = __importDefault(require("react"));
__importDefault
: If the module is not an es
module then what is returned by require becomes the default. This means that if you use default import on a commonjs
module, the whole module is actually the default.
__importStar
is best described in this PR:
TypeScript treats a namespace import (i.e.
import * as foo from "foo"
) as equivalent toconst foo = require("foo")
. Things are simple here, but they don't work out if the primary object being imported is a primitive or a value with call/construct signatures. ECMAScript basically says a namespace record is a plain object.Babel first requires in the module, and checks for a property named
__esModule
. If__esModule
is set totrue
, then the behavior is the same as that of TypeScript, but otherwise, it synthesizes a namespace record where:
- All properties are plucked off of the require'd module and made available as named imports.
- The originally require'd module is made available as a default import.
So we get this:
// ts
import * as React from 'react'
// emitted js
var __importStar = (this && this.__importStar) || function (mod) {
if (mod && mod.__esModule) return mod;
var result = {};
if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result["default"] = mod;
return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
var React = __importStar(require("react"));
allowSyntheticDefaultImports
is the companion to all of this, setting this to false will not change the emitted helpers (both of them will still look the same). But it will raise a typescript error if you are using default import for a commonjs module. So this import React from 'react'
will raise the error Module '".../node_modules/@types/react/index"' has no default export.
if allowSyntheticDefaultImports
is false
.
Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if
block.
public String foo(@Nullable String mayBeNothing) {
return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}
You can also throw some exception in there by swapping .orElse
to
orElseThrow(() -> new Exception("Dont' send a null"))
.
If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe...
so your intention is clear.
Just in case somebody land here... since 8.1 you can simply use:
SELECT user_id
FROM user_logs
WHERE login_date BETWEEN SYMMETRIC '2014-02-01' AND '2014-02-28'
From the docs:
BETWEEN SYMMETRIC is the same as BETWEEN except there is no requirement that the argument to the left of AND be less than or equal to the argument on the right. If it is not, those two arguments are automatically swapped, so that a nonempty range is always implied.
Here's some code for this -
String path = Environment.getExternalStorageDirectory().getAbsolutePath() +
"/Android/data/myapp/files/myfile.txt";
boolean exists = (new File(path)).exists();
if (!exists) {
doSomething();
}
else {
doSomethingElse();
}
I am promoting my comment to an answer:
The easy way is:
You could draw in the original 'frame' itself instead of using gray image.
The hard way (method you were trying to implement):
backtorgb = cv2.cvtColor(gray,cv2.COLOR_GRAY2RGB)
is the correct syntax.
[EDIT]
The expected output of the pluck
function has changed from Laravel 5.1 to 5.2. Hence why it is marked as deprecated in 5.1
In Laravel 5.1, pluck
gets a single column's value from the first result of a query.
In Laravel 5.2, pluck
gets an array with the values of a given column. So it's no longer deprecated, but it no longer do what it used to.
So short answer is use the value
function if you want one column from the first row and you are using Laravel 5.1 or above.
Thanks to Tomas Buteler for pointing this out in the comments.
[ORIGINAL] For anyone coming across this question who is using Laravel 5.1, pluck() has been deprecated and will be removed completely in Laravel 5.2.
Consider future proofing your code by using value()
instead.
return DB::table('users')->where('username', $username)->value('groupName');

Joshua Bloch's book has a whole chapter entitled "Item 10: Override Clone Judiciously" in which he goes into why overriding clone for the most part is a bad idea because the Java spec for it creates many problems.
He provides a few alternatives:
Use a factory pattern in place of a constructor:
public static Yum newInstance(Yum yum);
Use a copy constructor:
public Yum(Yum yum);
All of the collection classes in Java support the copy constructor (e.g. new ArrayList(l);)
The viewport is all that matters, but you likely want the entire website to stay darkened even while scrolling. For this, you want to use position:fixed
instead of position:absolute
. Fixed will keep the element static on the screen as you scroll, giving the impression that the entire body is darkened.
Example: http://jsbin.com/okabo3/edit
div.fadeMe {
opacity: 0.5;
background: #000;
width: 100%;
height: 100%;
z-index: 10;
top: 0;
left: 0;
position: fixed;
}
<body>
<div class="fadeMe"></div>
<p>A bunch of content here...</p>
</body>

I had a similar issue and found that pandas.get_dummies() solved the problem. Specifically, it splits out columns of categorical data into sets of boolean columns, one new column for each unique value in each input column. In your case, you would replace train_x = test[cols]
with:
train_x = pandas.get_dummies(test[cols])
This transforms the train_x Dataframe into the following form, which RandomForestClassifier can accept:
C A_Hello A_Hola B_Bueno B_Hi
0 0 1 0 0 1
1 1 0 1 1 0
i believe what you're looking for is the str.encode("string-escape") function. For example, if you have a variable that you want to 'raw string':

Note: Use string-escape
for python 2.x and older versions
I was searching for a similar solution and found the solution via: casting raw strings python
As everyone mentioned, it might not be a good idea for layout purposes. I arrived to this question because I was wondering the same and I only wanted to know if it would be valid code.
Since it's valid, you can use it for other purposes. For example, what I'm going to use it for is to put some fancy "CSSed" divs inside table rows and then use a quick jQuery function to allow the user to sort the information by price, name, etc. This way, the only layout table will give me is the "vertical order", but I'll control width, height, background, etc of the divs by CSS.

Wikipedia points out that the syntax of an IPv6 address includes colons and has a short form preventing fixed-length parsing, and therefore you have to delimit the address portion with []. This completely avoids the odd parsing errors.
(Taken from an edit Peter Wone made to the original question.)
In my case opening 'Help' >> "Install New Software" had no entries for any URLs (previous url's were not there) - so I Manually added 'em. And updated ... and Voilaaaa !! Above posts have been very helpful in resolving this issue for me.
I also have this problem. That is very stupid when i add a namespace the same with System. I try to remove all references, but it is not resolved. I use "global::System.ComponentModel", it is working as well. When i remove my namespace, this problem has been resolved.
I am using Laravel 5.4 and unfortunately although the accepted answer seems fine, for preflighted requests (like PUT
and DELETE
) which will be preceded by an OPTIONS
request, specifying the middleware in the $routeMiddleware
array (and using that in the routes definition file) will not work unless you define a route handler for OPTIONS
as well. This is because without an OPTIONS
route Laravel will internally respond to that method without the CORS headers.
So in short either define the middleware in the $middleware
array which runs globally for all requests or if you're doing it in $middlewareGroups
or $routeMiddleware
then also define a route handler for OPTIONS
. This can be done like this:
Route::match(['options', 'put'], '/route', function () {
// This will work with the middleware shown in the accepted answer
})->middleware('cors');
I also wrote a middleware for the same purpose which looks similar but is larger in size as it tries to be more configurable and handles a bunch of conditions as well:
<?php
namespace App\Http\Middleware;
use Closure;
class Cors
{
private static $allowedOriginsWhitelist = [
'http://localhost:8000'
];
// All the headers must be a string
private static $allowedOrigin = '*';
private static $allowedMethods = 'OPTIONS, GET, POST, PUT, PATCH, DELETE';
private static $allowCredentials = 'true';
private static $allowedHeaders = '';
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if (! $this->isCorsRequest($request))
{
return $next($request);
}
static::$allowedOrigin = $this->resolveAllowedOrigin($request);
static::$allowedHeaders = $this->resolveAllowedHeaders($request);
$headers = [
'Access-Control-Allow-Origin' => static::$allowedOrigin,
'Access-Control-Allow-Methods' => static::$allowedMethods,
'Access-Control-Allow-Headers' => static::$allowedHeaders,
'Access-Control-Allow-Credentials' => static::$allowCredentials,
];
// For preflighted requests
if ($request->getMethod() === 'OPTIONS')
{
return response('', 200)->withHeaders($headers);
}
$response = $next($request)->withHeaders($headers);
return $response;
}

private function isCorsRequest($request)
{
$requestHasOrigin = $request->headers->has('Origin');
if ($requestHasOrigin)
{
$origin = $request->headers->get('Origin');
$host = $request->getSchemeAndHttpHost();
if ($origin !== $host)
{
return true;
}
}
return false;
}

*/
private function resolveAllowedOrigin($request)
{
$allowedOrigin = static::$allowedOrigin;
// If origin is in our $allowedOriginsWhitelist
// then we send that in Access-Control-Allow-Origin
$origin = $request->headers->get('Origin');
if (in_array($origin, static::$allowedOriginsWhitelist))
{

Also written a blog post on this.
In EF 6.2 this works perfectly, sending the delete directly to the database without first loading the entities:
context.Widgets.Where(predicate).Delete();
With a fixed predicate it's quite straightforward:
context.Widgets.Where(w => w.WidgetId == widgetId).Delete();
And if you need a dynamic predicate have a look at LINQKit (Nuget package available), something like this works fine in my case:
Expression<Func<Widget, bool>> predicate = PredicateBuilder.New<Widget>(x => x.UserID == userID);
if (somePropertyValue != null)
{
predicate = predicate.And(w => w.SomeProperty == somePropertyValue);
}
context.Widgets.Where(predicate).Delete();
Recursion is a method that call itself. In this case it is a recursion. However it will be overloading until you put a restriction inside the method to stop the loop (if-condition).
I answer to myself. As suggested by Vadzim, I must consider the jboss-logging.xml file and insert these lines:
<logger category="org.hibernate">
<level name="TRACE"/>
</logger>
Instead of DEBUG level I wrote TRACE. Now don't look only the console but open the server.log file (debug messages aren't sent to the console but you can configure this mode!).
I think what you are looking for is iter_swap
which you can find also in <algorithm>
.
all you need to do is just pass two iterators each pointing at one of the elements you want to exchange.
since you have the position of the two elements, you can do something like this:
// assuming your vector is called v
iter_swap(v.begin() + position, v.begin() + next_position);
// position, next_position are the indices of the elements you want to swap
XSLT supports JSON as seen at http://www.w3.org/TR/xslt-30/#json
XML uses angular brackets for delimiter tokens, JSON uses braces, square brackets, ... I. e. XML's fewer token recognition comparisons means it's optimized for declarative transformation, whereas more comparisons, being like switch statement, for speed reasons assume speculative branch prediction that imperative code in scripting languages is useful for. As direct consequence, for different mixes of semi-structured data, you may want to benchmark XSLT and javascript engines' performance as part of responsive pages. For negligible data payload, transformations might work just as well with JSON without XML serialization. W3's decision ought to be based on better analysis.
You can only use await
in an async
method, and Main
cannot be async
.
You'll have to use your own async
-compatible context, call Wait
on the returned Task
in the Main
method, or just ignore the returned Task
and just block on the call to Read
. Note that Wait
will wrap any exceptions in an AggregateException
.
If you want a good intro, see my async
/await
intro post.
Since I needed this as well, I'll go into more detail on how to do this.
Note: I assume you used the standard template form for generating your UIPageViewController
structure - which has both the modelViewController
and dataViewController
created when you invoke it. If you don't understand what I wrote - go back and create a new project that uses the UIPageViewController
as it's basis. You'll understand then.
So, needing to flip to a particular page involves setting up the various pieces of the method listed above. For this exercise, I'm assuming that it's a landscape view with two views showing. Also, I implemented this as an IBAction so that it could be done from a button press or what not - it's just as easy to make it selector call and pass in the items needed.
So, for this example you need the two view controllers that will be displayed - and optionally, whether you're going forward in the book or backwards.
Note that I merely hard-coded where to go to pages 4 & 5 and use a forward slip. From here you can see that all you need to do is pass in the variables that will help you get these items...
-(IBAction) flipToPage:(id)sender {
// Grab the viewControllers at position 4 & 5 - note, your model is responsible for providing these.
// Technically, you could have them pre-made and passed in as an array containing the two items...
DataViewController *firstViewController = [self.modelController viewControllerAtIndex:4 storyboard:self.storyboard];
DataViewController *secondViewController = [self.modelController viewControllerAtIndex:5 storyboard:self.storyboard];
// Set up the array that holds these guys...
NSArray *viewControllers = nil;
viewControllers = [NSArray arrayWithObjects:firstViewController, secondViewController, nil];
// Now, tell the pageViewContoller to accept these guys and do the forward turn of the page.
// Again, forward is subjective - you could go backward. Animation is optional but it's
// a nice effect for your audience.
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
// Voila' - c'est fin!
}
I was also facing similar issues. I followed below mentioned steps and it worked for me:
go to Windows > Start > Node.js
Node.js command prompt
Run as administrator
ping registry.npmjs.org
npm view npm version
cd %ProgramFiles%\nodejs
npm install npm@latest
and npm updated successfully. Earlier I was trying for CMD and that was throwing error. may be some path issue that got resolved by running NodeJs Command Prompt. hope it'll work for you. try this.
For KDE Users you can use 'ctrl-esc' top call up a system actrivity monitor and there is I/O activities charts with process id and name.
I don't have permissions to upload image, due to 'new user status' but you can check out the image below. It has a column for IO read and write.

To click on a piece of the text (not the whole TextView
), you can use Html
or Linkify
(both create links that open urls, though, not a callback in the app).
Linkify
Use a string resource like:
<string name="links">Here is a link: http://www.stackoverflow.com</string>
Then in a textview:
TextView textView = ...
textView.setText(R.string.links);
Linkify.addLinks(textView, Linkify.ALL);
Html
Using Html.fromHtml
:
<string name="html">Here you can put html <a href="http://www.stackoverflow.com">Link!</></string>
Then in your textview:
textView.setText(Html.fromHtml(getString(R.string.html)));
I had a lot of problems with the complete load of a image and the EventListener.
Whatever I tried, the results was not reliable.
But then I found the solution. It is technically not a nice one, but now I never had a failed image load.
What I did:
document.getElementById(currentImgID).addEventListener("load", loadListener1);
document.getElementById(currentImgID).addEventListener("load", loadListener2);
function loadListener1()
{
// Load again
}
function loadListener2()
{
var btn = document.getElementById("addForm_WithImage"); btn.disabled = false;
alert("Image loaded");
}
Instead of loading the image one time, I just load it a second time direct after the first time and both run trough the eventhandler.
All my headaches are gone!
By the way: You guys from stackoverflow helped me already more then hundred times. For this a very big Thank you!
If you don't want to drag in libraries, it's simple enough to do yourself using a Formatter, or related shortcut eg. given integer number of seconds s:
String.format("%d:%02d:%02d", s / 3600, (s % 3600) / 60, (s % 60));
In my case, I came to this exception in two similar cases:
@Transactional
I had a call to another service (with long times of response). The method updates some properties of the entity (after the method, the entity still exists in the database). If the user requests two times the method (as he thinks it doesn't work the first time) when exiting from the transactional method the second time, Hibernate tries to update an entity which already changed its state from the beginning of the transaction. As Hibernate search for an entity in a state, and found the same entity but already changed by the first request, it throws an exception as it can't update the entity. It's like a conflict in GIT.Conclusion: in my case, it wasn't a problem which can be found in the code. This exception is thrown when Hibernate founds that the entity first fetched from the database changed during the current transaction, so it can't flush it to the database as Hibernate doesn't know which is the correct version of the entity: the one the current transaction fetch at the beginning; or the one already stored in the database.
Solution: to solve the problem, you will have to play with the Hibernate LockMode to find the one which best fit your requirements.
From the documentation:
list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, soa.insert(0, x)
inserts at the front of the list, anda.insert(len(a),x)
is equivalent toa.append(x)

Here is a good procedure for resetting any sequence to 0 from Oracle guru Tom Kyte. Great discussion on the pros and cons in the links below too.
[email protected]>
create or replace
procedure reset_seq( p_seq_name in varchar2 )
is
l_val number;
begin
execute immediate
'select ' || p_seq_name || '.nextval from dual' INTO l_val;
execute immediate
'alter sequence ' || p_seq_name || ' increment by -' || l_val ||
' minvalue 0';
execute immediate
'select ' || p_seq_name || '.nextval from dual' INTO l_val;
execute immediate
'alter sequence ' || p_seq_name || ' increment by 1 minvalue 0';
end;

From this page: Dynamic SQL to reset sequence value
Another good discussion is also here: How to reset sequences?
put your session() auth in all server side pages accepting an ajax request:
if(require_once("auth.php")) {
//run json code
}
// do nothing otherwise
that's about the only way I've ever done it.
A simple one liner using Java-8
Key key = Collections.max(map.entrySet(), Map.Entry.comparingByValue()).getKey();
I tried some of the other solutions listed here, but during unit testing the code would throw exceptions I wanted to ignore. I ended up creating the following recursive search method that will ignore certain exceptions like PathTooLongException and UnauthorizedAccessException.
private IEnumerable<string> RecursiveFileSearch(string path, string pattern, ICollection<string> filePathCollector = null)
{
try
{
filePathCollector = filePathCollector ?? new LinkedList<string>();
var matchingFilePaths = Directory.GetFiles(path, pattern);
foreach(var matchingFile in matchingFilePaths)
{
filePathCollector.Add(matchingFile);
}
var subDirectories = Directory.EnumerateDirectories(path);
foreach (var subDirectory in subDirectories)
{
RecursiveFileSearch(subDirectory, pattern, filePathCollector);
}
return filePathCollector;
}
catch (Exception error)
{
bool isIgnorableError = error is PathTooLongException ||
error is UnauthorizedAccessException;
if (isIgnorableError)
{
return Enumerable.Empty<string>();
}
throw error;
}
}
If you are using a data source, here's another way to do it without code behind.
Note the following key points:
ListItem
of Value="0"
is on the source page, not added in codeListItem
in the source will be overwritten if you don't include
AppendDataBoundItems="true"
in the DropDownList
InitialValue="0"
tells the validator that this is the value that
should fire that validator (as pointed out in other answers)Example:
<asp:DropDownList ID="ddlType" runat="server" DataSourceID="sdsType"
DataValueField="ID" DataTextField="Name" AppendDataBoundItems="true">
<asp:ListItem Value="0" Text="--Please Select--" Selected="True"></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rfvType" runat="server" ControlToValidate="ddlType"
InitialValue="0" ErrorMessage="Type required"></asp:RequiredFieldValidator>
<asp:SqlDataSource ID="sdsType" runat="server"
ConnectionString='<%$ ConnectionStrings:TESTConnectionString %>'
SelectCommand="SELECT ID, Name FROM Type"></asp:SqlDataSource>
I made this in my code to do that
note: I am a beginner.
It is my jsp code.
<%
java.sql.Connection Conn = DBconnector.SetDBConnection(); /* make connector as you make in your code */
Statement st = null;
ResultSet rs = null;
st = Conn.createStatement();
rs = st.executeQuery("select * from department"); %>
<tr>
<td>
Student Major : <select name ="Major">
<%while(rs.next()){ %>
<option value="<%=rs.getString(1)%>"><%=rs.getString(1)%></option>
<%}%>
</select>
</td>
<div style="display:none;">CREDITS_HERE</div>
the articles posted by Ricky are very good, but unfortunately they don't answer your question.
To solve your problem you should try this piece of code:
ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
configMap.ExeConfigFilename = @"d:\test\justAConfigFile.config.whateverYouLikeExtension";
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);
If need to access a value within the config you can use the index operator:
config.AppSettings.Settings["test"].Value;
Using Partitions in Hive table is highly recommended for below reason -
Example :-
Assume that Input File (100 GB) is loaded into temp-hive-table and it contains bank data from across different geographies.
Hive table without Partition
Insert into Hive table Select * from temp-hive-table
/hive-table-path/part-00000-1 (part size ~ hdfs block size)
/hive-table-path/part-00000-2
....
/hive-table-path/part-00000-n
Problem with this approach is - It will scan whole data for any query you run on this table. Response time will be high compare to other approaches where partitioning and Bucketing are used.
Hive table with Partition
Insert into Hive table partition(country) Select * from temp-hive-table
/hive-table-path/country=US/part-00000-1 (file size ~ 10 GB)
/hive-table-path/country=Canada/part-00000-2 (file size ~ 20 GB)
....
/hive-table-path/country=UK/part-00000-n (file size ~ 5 GB)
Pros - Here one can access data faster when it comes to querying data for specific geography transactions. Cons - Inserting/querying data can further be improved by splitting data within each partition. See Bucketing option below.
Hive table with Partition and Bucketing
Note: Create hive table ..... with "CLUSTERED BY(Partiton_Column) into 5 buckets
Insert into Hive table partition(country) Select * from temp-hive-table
/hive-table-path/country=US/part-00000-1 (file size ~ 2 GB)
/hive-table-path/country=US/part-00000-2 (file size ~ 2 GB)
/hive-table-path/country=US/part-00000-3 (file size ~ 2 GB)
/hive-table-path/country=US/part-00000-4 (file size ~ 2 GB)
/hive-table-path/country=US/part-00000-5 (file size ~ 2 GB)
/hive-table-path/country=Canada/part-00000-1 (file size ~ 4 GB)
/hive-table-path/country=Canada/part-00000-2 (file size ~ 4 GB)
/hive-table-path/country=Canada/part-00000-3 (file size ~ 4 GB)
/hive-table-path/country=Canada/part-00000-4 (file size ~ 4 GB)
/hive-table-path/country=Canada/part-00000-5 (file size ~ 4 GB)
....
/hive-table-path/country=UK/part-00000-1 (file size ~ 1 GB)
/hive-table-path/country=UK/part-00000-2 (file size ~ 1 GB)
/hive-table-path/country=UK/part-00000-3 (file size ~ 1 GB)
/hive-table-path/country=UK/part-00000-4 (file size ~ 1 GB)
/hive-table-path/country=UK/part-00000-5 (file size ~ 1 GB)
Pros - Faster Insert. Faster Query.
Cons - Bucketing will creating more files. There could be issue with many small files in some specific cases
Hope this will help !!
You may define your enum
like so and use cast where needed
public enum MyEnum
{
VariablePeriods = 1,
FixedPeriods = 2
}
Usage
public class Entity
{
public MyEnum Property { get; set; }
}
var returnedFromDB = 1;
var entity = new Entity();
entity.Property = (MyEnum)returnedFromDB;
Ok I have used the last week to massively rewrite my code to precisely fit your test. You can now copy this 1:1 and it will immediately work - including setSingleLine()
. Please remember to adjust MIN_TEXT_SIZE
and MAX_TEXT_SIZE
if you're going for extreme values.
Converging algorithm looks like this:
for (float testSize; (upperTextSize - lowerTextSize) > mThreshold;) {
// Go to the mean value...
testSize = (upperTextSize + lowerTextSize) / 2;
// ... inflate the dummy TextView by setting a scaled textSize and the text...
mTestView.setTextSize(TypedValue.COMPLEX_UNIT_SP, testSize / mScaledDensityFactor);
mTestView.setText(text);
// ... call measure to find the current values that the text WANTS to occupy
mTestView.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
int tempHeight = mTestView.getMeasuredHeight();
// ... decide whether those values are appropriate.
if (tempHeight >= targetFieldHeight) {
upperTextSize = testSize; // Font is too big, decrease upperSize
}
else {
lowerTextSize = testSize; // Font is too small, increase lowerSize
}
}
And the whole class can be found here.
The result is very flexible now. This works the same declared in xml like so:
<com.example.myProject.AutoFitText
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4"
android:text="@string/LoremIpsum" />
... as well as built programmatically like in your test.
I really hope you can use this now. You can call setText(CharSequence text)
now to use it by the way. The class takes care of stupendously rare exceptions and should be rock-solid. The only thing that the algorithm does not support yet is:
setMaxLines(x)
where x >= 2
But I have added extensive comments to help you build this if you wish to!
Please note:
If you just use this normally without limiting it to a single line then there might be word-breaking as you mentioned before. This is an Android feature, not the fault of the AutoFitText
. Android will always break words that are too long for a TextView and it's actually quite a convenience. If you want to intervene here than please see my comments and code starting at line 203. I have already written an adequate split and the recognition for you, all you'd need to do henceforth is to devide the words and then modify as you wish.
In conclusion: You should highly consider rewriting your test to also support space chars, like so:
final Random _random = new Random();
final String ALLOWED_CHARACTERS = "qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890";
final int textLength = _random.nextInt(80) + 20;
final StringBuilder builder = new StringBuilder();
for (int i = 0; i < textLength; ++i) {
if (i % 7 == 0 && i != 0) {
builder.append(" ");
}
builder.append(ALLOWED_CHARACTERS.charAt(_random.nextInt(ALLOWED_CHARACTERS.length())));
}
((AutoFitText) findViewById(R.id.textViewMessage)).setText(builder.toString());
This will produce very beutiful (and more realistic) results.
You will find commenting to get you started in this matter as well.
Good luck and best regards
You can define a "str_pad" function (as in php):
function str_pad(n) {
return String("00" + n).slice(-2);
}
Is correct?
<script>
$( "#box" ).one( "click", function() {
$( this ).css( "width", "+=200" );
});
</script>
If you are using an SQL script when you are creating your database and have any users created by your script, you need to drop them too. Lastly you need to flush the users; i.e., force MySQL to read the user's privileges again.
-- DELETE ALL RECIPE
drop schema <database_name>;
-- Same as `drop database <database_name>`
drop user <a_user_name>;
-- You may need to add a hostname e.g `drop user bob@localhost`
FLUSH PRIVILEGES;
Good luck!
A WC product may belong to none, one or more WC categories. Supposing you just want to get one WC category id.
global $post;
$terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($terms as $term) {
$product_cat_id = $term->term_id;
break;
}
Please look into the meta.php file in the "templates/single-product/" folder of the WooCommerce plugin.
<?php echo $product->get_categories( ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', sizeof( get_the_terms( $post->ID, 'product_cat' ) ), 'woocommerce' ) . ' ', '.</span>' ); ?>
Thew problem is because of spaces in the titles(Headers). Remove spaces in all headers and it works fine.
You can use ScriptEngine, example:
public class Main {
public static void main(String[] args) {
StringBuffer javascript = null;
ScriptEngine runtime = null;
try {
runtime = new ScriptEngineManager().getEngineByName("javascript");
javascript = new StringBuffer();
javascript.append("1 + 1");
double result = (Double) runtime.eval(javascript.toString());
System.out.println("Result: " + result);
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
}
Just use print_r
; ) Read the documentation:
If you would like to capture the output of
print_r()
, use thereturn
parameter. When this parameter is set toTRUE
,print_r()
will return the information rather than print it.
So this is one possibility:
$fp = fopen('file.txt', 'w');
fwrite($fp, print_r($array, TRUE));
fclose($fp);
Kotlin version with infix function
infix fun View.below(view: View) {
(this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.BELOW, view.id)
}
Then you can write:
view1 below view2
Or you can call it as a normal function:
view1.below(view2)

UNSIGNED
only stores positive numbers (or zero). On the other hand, signed can store negative numbers (i.e., may have a negative sign).
Here's a table of the ranges of values each INTEGER
type can store:
Source: http://dev.mysql.com/doc/refman/5.6/en/integer-types.html
UNSIGNED
ranges from 0
to n
, while signed ranges from about -n/2
to n/2
.
In this case, you have an AUTO_INCREMENT
ID column, so you would not have negatives. Thus, use UNSIGNED
. If you do not use UNSIGNED
for the AUTO_INCREMENT
column, your maximum possible value will be half as high (and the negative half of the value range would go unused).
Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.
The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.
delimiter //
create procedure myPivot(
in tableA varchar(255),
in columnA varchar(255),

Using jquery? I've used this before: http://projects.allmarkedup.com/jquery_url_parser/ and it worked pretty well.
As I recall, the only portable way to do it, is to cast the result to "unsigned long int" and use %lu
.
printf("sizeof(int) = %lu", (unsigned long) sizeof(int));
If you consider the extension as the last dot and the possible characters after it, but only if they don't contain the directory separator character, the following function returns the extension starting index, or -1 if no extension found. When you have that you can do what ever you want, like strip the extension, change it, check it etc.
long get_extension_index(string path, char dir_separator = '/') {
// Look from the end for the first '.',
// but give up if finding a dir separator char first
for(long i = path.length() - 1; i >= 0; --i) {
if(path[i] == '.') {
return i;
}
if(path[i] == dir_separator) {
return -1;
}
}
return -1;
}

Q. I would like to use a font such as "Bumble bee," for example. How can I use
@font-face
to make that font available on the user's computer?
Note that I don't know what the name of your Bumble Bee font or file is, so adjust accordingly, and that the font-face declaration should precede (come before) your use of it, as I've shown above.
Q. Can I still use the other
@font-face
typeface "GestaRegular" as well? Can I use both in the same stylesheet?
Just list them together as I've shown in my example. There is no reason you can't declare both. All that @font-face
does is instruct the browser to download and make a font-family available. See: http://iliadraznin.com/2009/07/css3-font-face-multiple-weights

Because Option 2 creates a new List
reference, and then creates an n
element array from the List
(option 1 perfectly sizes the output array). However, first you need to fix the off by one bug. Use <
(not <=
). Like,
String[] out = new String[n];
for(int i = 0; i < n; i++) {
out[i] = in.get(i);
}

As far as I know, there's no standard function to do so, but it's simple to achieve in the following manner:
#include <stdio.h>
int main(int argc, char **argv) {
const char hexstring[] = "DEadbeef10203040b00b1e50", *pos = hexstring;
unsigned char val[12];
/* WARNING: no sanitization or error-checking whatsoever */
for (size_t count = 0; count < sizeof val/sizeof *val; count++) {
sscanf(pos, "%2hhx", &val[count]);
pos += 2;
}
printf("0x");
for(size_t count = 0; count < sizeof val/sizeof *val; count++)
printf("%02x", val[count]);
printf("\n");
return 0;
}
As Al pointed out, in case of an odd number of hex digits in the string, you have to make sure you prefix it with a starting 0. For example, the string "f00f5"
will be evaluated as {0xf0, 0x0f, 0x05}
erroneously by the above example, instead of the proper {0x0f, 0x00, 0xf5}
.

Thanks, I didn't have the idea of an UPDATE with INNER JOIN.
In the original query, the mistake was to name the subquery, which must return a value and can't therefore be aliased.
UPDATE Competition
SET Competition.NumberOfTeams =
(SELECT count(*) -- no column alias
FROM PicksPoints
WHERE UserCompetitionID is not NULL
-- put the join condition INSIDE the subquery :
AND CompetitionID = Competition.CompetitionID
group by CompetitionID
) -- no table alias
should do the trick for every record of Competition.
To be noticed :
The effect is NOT EXACTLY the same as the query proposed by mellamokb, which won't update Competition records with no corresponding PickPoints.
Since SELECT id, COUNT(*) GROUP BY id
will only count for existing values of ids,
whereas a SELECT COUNT(*)
will always return a value, being 0 if no records are selected.
This may, or may not, be a problem for you.
0-aware version of mellamokb query would be :
Update Competition as C
LEFT join (
select CompetitionId, count(*) as NumberOfTeams
from PicksPoints as p
where UserCompetitionID is not NULL
group by CompetitionID
) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = IFNULL(A.NumberOfTeams, 0)
In other words, if no corresponding PickPoints are found, set Competition.NumberOfTeams to zero.

You can try to write a custom function like that.
The main advantage of the approach is a type-checking and partial intellisense.
export function nullSafe<T,
K0 extends keyof T,
K1 extends keyof T[K0],
K2 extends keyof T[K0][K1],
K3 extends keyof T[K0][K1][K2],
K4 extends keyof T[K0][K1][K2][K3],
K5 extends keyof T[K0][K1][K2][K3][K4]>
(obj: T, k0: K0, k1?: K1, k2?: K2, k3?: K3, k4?: K4, k5?: K5) {
let result: any = obj;
const keysCount = arguments.length - 1;
for (var i = 1; i <= keysCount; i++) {
if (result === null || result === undefined) return result;
result = result[arguments[i]];
}
return result;
}
And usage (supports up to 5 parameters and can be extended):
nullSafe(a, 'b', 'c');

If you want your script to return values, just do return [1,2,3]
from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:
(again, this would have to be run by a separate Python script and be imported in order to even do any good):
import ...
def main():
# calculate stuff
return [1,2,3]
(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)
import sys
# calculate and stuff
sys.exit(100)
And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.
(os._exit(100)
also works, and is a bit more forceful)
If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.
import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)
Are you running your script in a controlled scheduling environment then exit codes are the best way to go.
There's also the option to simply write information to a file, and store the result there.
# calculate
with open('finish.txt', 'wb') as fh:
fh.write(str(5)+'\n')
And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.
If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.
I really think your going about this in the wrong manner. Trying to download and parse a +3Mb text file is complete insanity. Why not parse the file on the server side, storing the results viva an ORM to a database(your choice, SQL is good but it also depends on the content key-value data works better on something like CouchDB) then use ajax to parse data on the client end.
Plus, an even better idea would to skip the text file entirely for even better performance if at all possible.
This is another way:
irb> [*1..10]

Seems to be a common feature of the prevalent asymmetric cryptography; the generation of public/private keys involves generating the private key, which contains the key pair:
openssl genrsa -out mykey.pem 1024
Then publish the public key:
openssl rsa -in mykey.pem -pubout > mykey.pub
or
openssl rsa -in mykey.pem -pubout -out mykey.pub
DSA & EC crypto keys have same feature: eg.
openssl genpkey -algorithm ed25519 -out pvt.pem
Then
openssl pkey -in pvt.pem -pubout > public.pem
or
openssl ec -in ecprivkey.pem -pubout -out ecpubkey.pem
The public component is involved in decryption, and keeping it as part of the private key makes decryption faster; it can be removed from the private key and calculated when needed (for decryption), as an alternative or complement to encrypting or protecting the private key with a password/key/phrase. eg.
openssl pkey -in key.pem -des3 -out keyout.pem
or
openssl ec -aes-128-cbc -in pk8file.pem -out tradfile.pem
You can replace the first argument "aes-128-cbc" with any other valid openssl cipher name
You should put this line in your application context:

Ok, was having this issue as well and this is what fixed it for me. For the record I'm using Windows 8.1 and Java JDK 1.8.31, all 64-bit.
The problem is with the space between "Program" and "Files" in the path set in JAVA_HOME
. I've had this problem before but didn't really realize until I was checking the instructions here for setting JAVA HOME
, then it all made sense.
In a nutshell, change the JAVA_HOME
path from:
C:\Program Files\Java\jdk1.8.0_31
to
C:\Progra~1\Java\jdk1.8.0_31
Make sure to set the correct JDK version number for your installation. Removing the space from the path fixed everything on my system.
As noted on the page linked above,
use C:\Progra~1\
for C:\Program Files\
and C:\Progra~2\
for C:\Program Files(x86)\
depending on where you have the JDK installed on your system.
Note: Just to be clear, before making this change my system correctly echoed the value of JAVA_HOME
to be C:\Program Files\Java\jdk1.8.0_31
in the command window, leading me to believe all was well. However, attempting to run %JAVA_HOME%\bin\javac
reported that the path could not be found. After removing the space from the JAVA_HOME
path the same command runs perfectly.
The same way Boston came up with its street plan. They followed the cow paths already there, and built houses where the streets weren't, and after a while it was too much trouble to change.
You can try this method:

For anyone looking for a clean way to encode a POST request in Swift 5.
You don’t need to deal with manually adding percent encoding.
Use URLComponents
to create a GET request URL. Then use query
property of that URL to get properly percent escaped query string.
let url = URL(string: "https://example.com")!
var components = URLComponents(url: url, resolvingAgainstBaseURL: false)!
components.queryItems = [
URLQueryItem(name: "key1", value: "NeedToEscape=And&"),
URLQueryItem(name: "key2", value: "vålüé")
]
let query = components.url!.query
The query
will be a properly escaped string:
key1=NeedToEscape%3DAnd%26&key2=v%C3%A5l%C3%BC%C3%A9
Now you can create a request and use the query as HTTPBody:
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = Data(query.utf8)
Now you can send the request.
If you want to use column names to select the columns, simply use .()
, which is an alias for list()
:
library(data.table)
dt <- data.table(a = 1:2, b = 2:3, c = 3:4)
dt[ , .(b, c)] # select the columns b and c
# Result:
# b c
# 1: 2 3
# 2: 3 4
When I was recently looking for an R function returning indexes of top N max/min numbers in a given vector, I was surprised there is no such a function.
And this is something very similar.
The brute force solution using base::order function seems to be the easiest one.
topMaxUsingFullSort <- function(x, N) {
sort(x, decreasing = TRUE)[1:min(N, length(x))]
}
But it is not the fastest one in case your N value is relatively small compared to length of the vector x.
On the other side if the N is really small, you can use base::whichMax function iteratively and in each iteration you can replace found value by -Inf
# the input vector 'x' must not contain -Inf value
topMaxUsingWhichMax <- function(x, N) {
vals <- c()
for(i in 1:min(N, length(x))) {
idx <- which.max(x)
vals <- c(vals, x[idx]) # copy-on-modify (this is not an issue because idxs is relative small vector)
x[idx] <- -Inf # copy-on-modify (this is the issue because data vector could be huge)
}
vals
}
I believe you see the problem - the copy-on-modify nature of R. So this will perform better for very very very small N (1,2,3) but it will rapidly slow down for larger N values. And you are iterating over all elements in vector x N times.
I think the best solution in clean R is to use partial base::sort.
topMaxUsingPartialSort <- function(x, N) {
N <- min(N, length(x))
x[x >= -sort(-x, partial=N)[N]][1:N]
}
Then you can select the last (Nth) item from the result of functions defiend above.
Note: functions defined above are just examples - if you want to use them, you have to check/sanity inputs (eg. N > length(x)).
I wrote a small article about something very similar (get indexes of top N max/min values of a vector) at http://palusga.cz/?p=18 - you can find here some benchmarks of similar functions I defined above.
Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:
<Router>
<Route path="/" component={App}>
<Route path="page1" component={Page1} />
<Route path="page2" component={Page2} />
</Route>
<Route path="/login" component={Login} />
</Router>
And the other components would look something like this:
var NavBar = React.createClass({
render() {
return (
<div>
<ul>
<a onClick={() => history.push('page1') }>Page 1</a>
<a onClick={() => history.push('page2') }>Page 2</a>
</ul>
</div>
)
}
});
var App = React.createClass({
render() {
return (
<div>
<NavBar />
<div>Other Content</div>
{this.props.children}
</div>
)
}
});

Lot of people assumes Eclipse and maven intergration is tough but its very eassy.
1) download the maven and unzip it in to your favorite directory.
Ex : C:\satyam\DEV_TOOLS\apache-maven-3.1.1
2) Set the environment variable for Maven(Hope every one knows where to go to set this)
In the system variable: Variable_name = M2_HOME Variable_Value =C:\satyam\DEV_TOOLS\apache-maven-3.1.1
Next in the same System Variable you will find the variable name called Path: just edit the path variable and add M2_HOME details like with the existing values.
%M2_HOME%/bin;
so in the second step now you are done setting the Maven stuff to your system.you need to cross check it whether your setting is correct or not, go to command prompt and type mvn--version it should disply the path of your Maven
3) Open the eclipse and go to Install new software and type M2E Plugin install and restart the Eclipse
with the above 3 steps you are done with Maven and Maven Plugin with eclipse
4) Maven is used .m2 folder to download all the jars, it will find in Ex: C:\Users\tempsakat.m2
under this folder one settings.xml file and one repository folder will be there
5) go to Windwo - preferences of your Eclipse and type Maven then select UserSettings from left menu then give the path of the settings.xml here .
now you are done...
You can get its shape
with:
print((df.count(), len(df.columns)))
What system are you running on? Do you have access to some sort of debugger (gdb, visual studio's debugger, etc.)?
That would give us valuable information, like the line of code where the program crashes... Also, the amount of memory may be prohibitive.
Additionally, may I recommend that you replace the numeric limits by named definitions?
As such:
#define DIM1_SZ 1000
#define DIM2_SZ 1000000
Use those whenever you wish to refer to the array dimension limits. It will help avoid typing errors.
ES6 modules support in Node.js is fairly recent; even in the bleeding-edge versions, it is still experimental. With Node.js 10, you can start Node.js with the --experimental-modules
flag, and it will likely work.
To import on older Node.js versions - or standard Node.js 10 - use CommonJS syntax:
const fs = require('fs');
For what it's worth.

In Java8 you can do it with CompletableFuture:
ExecutorService es = Executors.newFixedThreadPool(4);
List<Runnable> tasks = getTasks();
CompletableFuture<?>[] futures = tasks.stream()
.map(task -> CompletableFuture.runAsync(task, es))
.toArray(CompletableFuture[]::new);
CompletableFuture.allOf(futures).join();
es.shutdown();
I use CALayer to mask the given image with Alpha Channel
import Foundation
extension UIImage {
func maskWithColor(color: UIColor) -> UIImage? {
let maskLayer = CALayer()
maskLayer.bounds = CGRect(x: 0, y: 0, width: size.width, height: size.height)
maskLayer.backgroundColor = color.cgColor
maskLayer.doMask(by: self)
let maskImage = maskLayer.toImage()
return maskImage
}
}
extension CALayer {
func doMask(by imageMask: UIImage) {
let maskLayer = CAShapeLayer()
maskLayer.bounds = CGRect(x: 0, y: 0, width: imageMask.size.width, height: imageMask.size.height)
bounds = maskLayer.bounds
maskLayer.contents = imageMask.cgImage
maskLayer.frame = CGRect(x: 0, y: 0, width: frame.size.width, height: frame.size.height)
mask = maskLayer
}
func toImage() -> UIImage?
{
UIGraphicsBeginImageContextWithOptions(bounds.size,
isOpaque,
UIScreen.main.scale)
guard let context = UIGraphicsGetCurrentContext() else {
UIGraphicsEndImageContext()
return nil
}
render(in: context)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
}
You can 'goto case label' http://www.blackwasp.co.uk/CSharpGoto.aspx
The goto statement is a simple command that unconditionally transfers the control of the program to another statement. The command is often criticised with some developers advocating its removal from all high-level programming languages because it can lead to spaghetti code. This occurs when there are so many goto statements or similar jump statements that the code becomes difficult to read and maintain. However, there are programmers who point out that the goto statement, when used carefully, provides an elegant solution to some problems...
From the npm docs:
git://github.com/<user>/<project>.git#<branch>
git://github.com/<user>/<project>.git#feature\/<branch>
As of NPM version 1.1.65, you can do this:
<user>/<project>#<branch>
Using Eddy's answer worked very well as I had kind of the same problem. Just call your url with the parameters : "www.mypage.html#myAnchor"
Then, in mypage.html :
$(document).ready(function(){
var hash = window.location.hash;
if(hash.length > 0){
// your action with the hash
}
});
I like to use
git stash
This stores all uncommitted changes in the stash. If you want to discard these changes later just git stash drop
(or git stash pop
to restore them).
Though this is technically not the "proper" way to discard changes (as other answers and comments have pointed out).
SourceTree: On the top bar click on icon 'Stash', type its name and create. Then in left vertical menu you can "show" all Stash and delete in right-click menu. There is probably no other way in ST to discard all files at once.
The syntax function[i](){}
implies an object with property values that are functions, function[]
, indexed by the name, [i]
.
Thus
{"f:1":function(){}, "f:2":function(){}, "f:A":function(){}, ... } ["f:"+i]
.
{"f:1":function f1(){}, "f:2":function f2(){}, "f:A":function fA(){}} ["f:"+i]
will preserve function name identification. See notes below regarding :
.
So,
javascript: alert(
new function(a){
this.f={"instance:1":function(){}, "instance:A":function(){}} ["instance:"+a]
}("A") . toSource()
);
displays ({f:(function () {})})
in FireFox.
(This is almost the same idea as this solution, only it uses a generic object and no longer directly populates the window object with the functions.)
This method explicitly populates the environment with instance:x
.
javascript: alert(
new function(a){
this.f=eval("instance:"+a+"="+function(){})
}("A") . toSource()
);
alert(eval("instance:A"));
displays
({f:(function () {})})
and
function () {
}
Though the property function f
references an anonymous function
and not instance:x
, this method avoids several problems with this solution.
javascript: alert(
new function(a){
eval("this.f=function instance"+a+"(){}")
}("A") . toSource()
);
alert(instanceA); /* is undefined outside the object context */
displays only
({f:(function instanceA() {})})
:
makes the javascript function instance:a(){}
invalid.eval
.The following is not necessarily problematic,
instanceA
function is not directly available for use as instanceA()
and so is much more consistent with the original problem context.
Given these considerations,
this.f = {"instance:1": function instance1(){},
"instance:2": function instance2(){},
"instance:A": function instanceA(){},
"instance:Z": function instanceZ(){}
} [ "instance:" + a ]
maintains the global computing environment with the semantics and syntax of the OP example as much as possible.

There is contextlib.redirect_stdout() function in Python 3.4:
import io
from contextlib import redirect_stdout
with io.StringIO() as buf, redirect_stdout(buf):
print('redirected')
output = buf.getvalue()
Here's code example that shows how to implement it on older Python versions.
If you are trying to upload an array of files then you may need to increase max_file_uploads
in php.ini
which is by default set to 20
Note: max_file_uploads
can NOT be changed outside php.ini. See PHP "Bug" #50684
You can use cut
to split the line on spaces and return only the first such field:
md5=$(md5sum "$my_iso_file" | cut -d ' ' -f 1)
When a dictionary is enumerated, it will yield KeyValuePair<TKey,TValue>
objects... so you just need to specify "Value" and "Key" for DataTextField
and DataValueField
respectively, to select the Value/Key properties.
Thanks to Joe's comment, I reread the question to get these the right way round. Normally I'd expect the "key" in the dictionary to be the text that's displayed, and the "value" to be the value fetched. Your sample code uses them the other way round though. Unless you really need them to be this way, you might want to consider writing your code as:
list.Add(cul.DisplayName, cod);
(And then changing the binding to use "Key" for DataTextField
and "Value" for DataValueField
, of course.)
In fact, I'd suggest that as it seems you really do want a list rather than a dictionary, you might want to reconsider using a dictionary in the first place. You could just use a List<KeyValuePair<string, string>>
:
string[] languageCodsList = service.LanguagesAvailable();
var list = new List<KeyValuePair<string, string>>();
foreach (string cod in languageCodsList)
{
CultureInfo cul = new CultureInfo(cod);
list.Add(new KeyValuePair<string, string>(cul.DisplayName, cod));
}
Alternatively, use a list of plain CultureInfo
values. LINQ makes this really easy:
var cultures = service.LanguagesAvailable()
.Select(language => new CultureInfo(language));
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();
If you're not using LINQ, you can still use a normal foreach loop:
List<CultureInfo> cultures = new List<CultureInfo>();
foreach (string cod in service.LanguagesAvailable())
{
cultures.Add(new CultureInfo(cod));
}
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();
A comment by madeddie looks most elegant to me:
CID=$(basename $(cat /proc/1/cpuset))
Declaring inside the loop limits the scope of the respective variable. It all depends on the requirement of the project on the scope of the variable.
Are there other ways?
Negative margins were also used for horizontal (and vertical!) centering but there are quite a few drawbacks when you resize the window browser: no window slider; the content can't be seen anymore if the size of the window browser is too small.
No surprise as it uses absolute positioning, a beast never completely tamed!
Example: http://bluerobot.com/web/css/center2.html
So that was only FYI as you asked for it, margin: 0 auto;
is a better solution.
If the condition isn't satisfied, an AssertionError
will be thrown.
Assertions have to be enabled, though; otherwise the assert
expression does nothing. See:
http://java.sun.com/j2se/1.5.0/docs/guide/language/assert.html#enable-disable
This answer is very late but what I do is set a class that holds Booleans, arrays, and integer-initial values as global scope static variables. Any constant strings are defined as such.
define("myconstant", "value");
class globalVars {
static $a = false;
static $b = 0;
static $c = array('first' => 2, 'second' => 5);
}
function test($num) {
if (!globalVars::$a) {
$returnVal = 'The ' . myconstant . ' of ' . $num . ' plus ' . globalVars::$b . ' plus ' . globalVars::$c['second'] . ' is ' . ($num + globalVars::$b + globalVars::$c['second']) . '.';
globalVars::$a = true;
} else {
$returnVal = 'I forgot';
}
return $returnVal;
}
echo test(9); ---> The value of 9 + 0 + 5 is 14.
echo "<br>";
echo globalVars::$a; ----> 1
The static
keywords must be present in the class else the vars $a, $b, and $c will not be globally scoped.

If you need to get all td's inside tr without defining id for them, you can use the code below :
var items = new Array();
$('#TABLE_ID td:nth-child(1)').each(function () {
items.push($(this).html());
});
The code above will add all first cells inside the Table into an Array variable.
you can change nth-child(1) which means the first cell to any cell number you need.
hope this code helps you.
It could be easily achieved with CSS flex. Having HTML markup as follows:
<html>
<body>
<div class="container"></div>
<div class="footer"></div>
</body>
</html>
Following CSS should be used:
html {
height: 100%;
}
body {
min-height: 100%;
display: flex;
flex-direction: column;
}
body > .container {
flex-grow: 1;
}
Here's CodePen to play with: https://codepen.io/webdevchars/pen/GPBqWZ
This one, from kristopherjohnson is heaps better:
Less lines of code
static string PrettyXml(string xml)
{
var stringBuilder = new StringBuilder();
var element = XElement.Parse(xml);
var settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Indent = true;
settings.NewLineOnAttributes = true;
using (var xmlWriter = XmlWriter.Create(stringBuilder, settings))
{
element.Save(xmlWriter);
}
return stringBuilder.ToString();
}
