Instead of only using the path to your script in the task scheduler, you should start PowerShell with your script in the task scheduler, e.g.

C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -NoLogo -NonInteractive -File "C:\Path\To\Your\PS1File.ps1"

See powershell /? for an explanation of those switches.

If you still get problems you should read this question.

This is an elaboration on @Jeff M's and my comments.

When you do this:

a, b = c, d

It works with tuple packing and unpacking. You can separate the packing and unpacking steps:

_ = c, d
a, b = _

The first line creates a tuple called _ which has two elements, the first with the value of c and the second with the value of d. The second line unpacks the _ tuple into the variables a and b. This breaks down your one huge line:

a, b, c, d, e, f, g, h, i, j = True, True, True, True, True, False, True, True, True, True

Into two smaller lines:

_ = True, True, True, True, True, False, True, True, True, True
a, b, c, d, e, f, g, h, i, j = _

It will give you the exact same result as the first line (including the same exception if you add values or variables to one part but forget to update the other). However, in this specific case, yan's answer is perhaps the best.

If you have a list of values, you can still unpack them. You just have to convert it to a tuple first. For example, the following will assign a value between 0 and 9 to each of a through j, respectively:

a, b, c, d, e, f, g, h, i, j = tuple(range(10))

EDIT: Neat trick to assign all of them as true except element 5 (variable f):

a, b, c, d, e, f, g, h, i, j = tuple(x != 5 for x in range(10))

There is one usage I can see everyone here seems to have forgotten to list...

Rather than doing this:

List("foo", "bar", "baz").map(n => n.toUpperCase())

You could can simply do this:

List("foo", "bar", "baz").map(_.toUpperCase())

From the bash manpage:

[[ expression ]] - return a status of 0 or 1 depending on the evaluation of the conditional expression expression.

And, for expressions, one of the options is:

expression1 && expression2 - true if both expression1 and expression2 are true.

So you can and them together as follows (-n is the opposite of -z so we can get rid of the !):

if [[ -n "$var" && -e "$var" ]] ; then
    echo "'$var' is non-empty and the file exists"
fi

However, I don't think it's needed in this case, -e xyzzy is true if the xyzzy file exists and can quite easily handle empty strings. If that's what you want then you don't actually need the -z non-empty check:

pax> VAR=xyzzy
pax> if [[ -e $VAR ]] ; then echo yes ; fi
pax> VAR=/tmp
pax> if [[ -e $VAR ]] ; then echo yes ; fi
yes

In other words, just use:

if [[ -e "$var" ]] ; then
    echo "'$var' exists"
fi

Your FMAT.h requires a definition of std::string in order to complete the definition of class FMAT. In FMAT.cpp, you've done this by #include <string> before #include "FMAT.h". You haven't done that in your main file.

Your attempt to forward declare string was incorrect on two levels. First you need a fully qualified name, std::string. Second this works only for pointers and references, not for variables of the declared type; a forward declaration doesn't give the compiler enough information about what to embed in the class you're defining.

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

ToList will always create a new list, which will not reflect any subsequent changes to the collection.

However, it will reflect changes to the objects themselves (Unless they're mutable structs).

In other words, if you replace an object in the original list with a different object, the ToList will still contain the first object.
However, if you modify one of the objects in the original list, the ToList will still contain the same (modified) object.

THIS ANSWER IS FOR ANIMATIONS ONLY


If you wanna implement the AND logic, you should use MultiTrigger, here is an example:

Suppose we want to do some actions if the property Text="" (empty string) AND IsKeyboardFocused="False", then your code should look like the following:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
        <MultiTrigger.EnterActions>
            <!-- Your actions here -->
        </MultiTrigger.EnterActions>
</MultiTrigger>

If you wanna implement the OR logic, there are couple of ways, and it depends on what you try to do:

The first option is to use multiple Triggers.
So, suppose you wanna do something if either Text="" OR IsKeyboardFocused="False",
then your code should look something like this:

<Trigger Property="IsEnabled" Value="false">
    <Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
    <Setter Property="BorderBrush" TargetName="border" 
            Value="{StaticResource TextBox.MouseOver.Border}"/>
</Trigger>

But the problem in this is what will I do if i wanna do something if either Text ISN'T null OR IsKeyboard="True"? This can be achieved by the second approach:
Recall De Morgan's rule, that says !(!x && !y) = x || y.
So we'll use it to solve the previous problem, by writing a multi trigger that it's triggered when Text="" and IsKeyboard="True", and we'll do our actions in EXIT ACTIONS, like this:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
    <MultiTrigger.ExitActions>
        <!-- Do something here -->
    </MultiTrigger.ExitActions>
</MultiTrigger>

Thus far, nobody seems to have addressed the memory footprint of each of these lists besides the general consensus that a LinkedList is "lots more" than an ArrayList so I did some number crunching to demonstrate exactly how much both lists take up for N null references.

Since references are either 32 or 64 bits (even when null) on their relative systems, I have included 4 sets of data for 32 and 64 bit LinkedLists and ArrayLists.

Note: The sizes shown for the ArrayList lines are for trimmed lists - In practice, the capacity of the backing array in an ArrayList is generally larger than its current element count.

Note 2: (thanks BeeOnRope) As CompressedOops is default now from mid JDK6 and up, the values below for 64-bit machines will basically match their 32-bit counterparts, unless of course you specifically turn it off.

The result clearly shows that LinkedList is a whole lot more than ArrayList, especially with a very high element count. If memory is a factor, steer clear of LinkedLists.

The formulas I used follow, let me know if I have done anything wrong and I will fix it up. 'b' is either 4 or 8 for 32 or 64 bit systems, and 'n' is the number of elements. Note the reason for the mods is because all objects in java will take up a multiple of 8 bytes space regardless of whether it is all used or not.

ArrayList:

ArrayList object header + size integer + modCount integer + array reference + (array oject header + b * n) + MOD(array oject, 8) + MOD(ArrayList object, 8) == 8 + 4 + 4 + b + (12 + b * n) + MOD(12 + b * n, 8) + MOD(8 + 4 + 4 + b + (12 + b * n) + MOD(12 + b * n, 8), 8)

LinkedList:

LinkedList object header + size integer + modCount integer + reference to header + reference to footer + (node object overhead + reference to previous element + reference to next element + reference to element) * n) + MOD(node object, 8) * n + MOD(LinkedList object, 8) == 8 + 4 + 4 + 2 * b + (8 + 3 * b) * n + MOD(8 + 3 * b, 8) * n + MOD(8 + 4 + 4 + 2 * b + (8 + 3 * b) * n + MOD(8 + 3 * b, 8) * n, 8)

Maybe a helpful alternative for a plain-colored background:

Put a LinearLayout over the ImageView and use the LinearLayout as a opacity filter. In the following a small example with a black background:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000" >

<RelativeLayout
    android:id="@+id/relativeLayout2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/icon_stop_big" />

    <LinearLayout
        android:id="@+id/opacityFilter"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#CC000000"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

Vary the android:background attribute of the LinearLayout between #00000000 (fully transparent) and #FF000000 (fully opaque).

Update August 2020

As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x

git push --atomic origin <branch name> <tag>

(Note: this actually work with HTTPS only with Git 2.24)

Update May 2015

As of git 2.4.1, you can do

git config --global push.followTags true

If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.

As noted in this thread by Matt Rogers answering Wes Hurd:

--follow-tags only pushes annotated tags.

git tag -a -m "I'm an annotation" <tagname>

That would be pushed (as opposed to git tag <tagname>, a lightweight tag, which would not be pushed, as I mentioned here)

Update April 2013

Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:

The new "--follow-tags" option tells "git push" to push relevant annotated tags when pushing branches out.

You can now try, when pushing new commits:

git push --follow-tags

That won't push all the local tags though, only the one referenced by commits which are pushed with the git push.

Git 2.4.1+ (Q2 2015) will introduce the option push.followTags: see "How to make “git push” include tags within a branch?".

Original answer, September 2010

The nuclear option would be git push --mirror, which will push all refs under refs/.

You can also push just one tag with your current branch commit:

git push origin : v1.0.0 

You can combine the --tags option with a refspec like:

git push origin --tags :

(since --tags means: All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line)

You also have this entry "Pushing branches and tags with a single "git push" invocation"

A handy tip was just posted to the Git mailing list by Zoltán Füzesi:

I use .git/config to solve this:

[remote "origin"]
    url = ...
    fetch = +refs/heads/*:refs/remotes/origin/*
    push = +refs/heads/*
    push = +refs/tags/*

With these lines added git push origin will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.

Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:

$ git push && git push --tags

Beware, as commented by Aseem Kishore

push = +refs/heads/* will force-pushes all your branches.

This bit me just now, so FYI.

René Scheibe adds this interesting comment:

The --follow-tags parameter is misleading as only tags under .git/refs/tags are considered.
If git gc is run, tags are moved from .git/refs/tags to .git/packed-refs. Afterwards git push --follow-tags ... does not work as expected anymore.

In my case, changing the webpage:Version to the proper value resolved my issue, for me the correct value was(2.0.0.0 instead of 3.0.0.0) :

<appSettings>
        <add key="webpages:Version" value="2.0.0.0"/>
        <add key="webpages:Enabled" value="false"/>

I am not aware of any solution for the second part of your question. The reason is that it is not clear how to define I changed. Changed when? Just between 2 saves or between commits... Basically - forget it.

I assume you would like to stick to some guideline, but do not touch the rest of the code. But the guideline should be used overall, and not for bites and pieces. So my suggestion is - change all the code to the guideline: it is once-off operation, but make sure that all your developers have the same plugin (AnyEdit) with the same settings for the project.

Quick and dirty solution for predefined log levels and without defining a new class.

logging.addLevelName( logging.WARNING, "\033[1;31m%s\033[1;0m" % logging.getLevelName(logging.WARNING))
logging.addLevelName( logging.ERROR, "\033[1;41m%s\033[1;0m" % logging.getLevelName(logging.ERROR))

All you have to do is In your bLoanButton_Click , add a line to rebind the Grid to the SqlDataSource :

protected void bLoanButton_Click(object sender, EventArgs e)
{

//your same code
........

GridView1.DataBind();

There are lots of data types you can mention while creating model, some examples are:

:primary_key, :string, :text, :integer, :float, :decimal, :datetime, :timestamp, :time, :date, :binary, :boolean, :references

syntax:

field_type:data_type

First check if you have configured JDK correctly:

• Go to File->Project Structure -> SDKs
• your JDK home path should be something like this: /Library/Java/JavaVirtualMachine/jdk.1.7.0_79.jdk/Contents/Home
• Hit Apply and then OK

Secondly check if you have provided in path in Library's section

• Go to File->Project Structure -> Libraries
• Hit the + button
• Add the path to your src folder
• Hit Apply and then OK

This should fix the problem

The datetime class has a method strftime. The Python docs documents the different formats it accepts:

• Python 2: strftime() Behavior
• Python 3: strftime() Behavior

For this specific example, it would look something like:

my_datetime.strftime("%B %d, %Y")

This is not an answer to your original question, but a better way of doing what you're trying to do:

Instead of actually trying to get the site's favicon directly (which is a royal pain given it could be /favicon.png, /favicon.ico, /favicon.gif, or even /path/to/favicon.png), use google:

<img src="http://www.google.com/s2/favicons?domain=[domain]">

Done.

This will do what you want:

select * 
  from orders_products 
       INNER JOIN orders 
          ON orders_products.orders_id = orders.orders_id
 where products_id in (180, 181);

You have to set seed every time you want to get a reproducible random result.

set.seed(1)
rnorm(4)
set.seed(1)

urlretrieve and requests.get are simple, however the reality not. I have fetched data for couple sites, including text and images, the above two probably solve most of the tasks. but for a more universal solution I suggest the use of urlopen. As it is included in Python 3 standard library, your code could run on any machine that run Python 3 without pre-installing site-package

import urllib.request
url_request = urllib.request.Request(url, headers=headers)
url_connect = urllib.request.urlopen(url_request)

#remember to open file in bytes mode
with open(filename, 'wb') as f:
    while True:
        buffer = url_connect.read(buffer_size)
        if not buffer: break

        #an integer value of size of written data
        data_wrote = f.write(buffer)

#you could probably use with-open-as manner
url_connect.close()

This answer provides a solution to HTTP 403 Forbidden when downloading file over http using Python. I have tried only requests and urllib modules, the other module may provide something better, but this is the one I used to solve most of the problems.

Here are some benchmarks comparing different approaches and libraries. Guava beats Apache Commons Codec at decoding. Commons Codec beats Guava at encoding. And JHex beats them both for decoding and encoding.

JHex example

String hexString = "596f752772652077656c636f6d652e";
byte[] decoded = JHex.decodeChecked(hexString);
System.out.println(new String(decoded));
String reEncoded = JHex.encode(decoded);

Everything is in a single class file for JHex. Feel free to copy paste if you don't want yet another library in your dependency tree. Also note, it is only available as Java 9 jar until I can figure out how to publish multiple release targets with Gradle and the Bintray plugin.

While I myself would be waiting here for an answer, I wonder if it can be done via CSS:

@media only screen and (orientation:portrait){
#wrapper {width:1024px}
}

@media only screen and (orientation:landscape){
#wrapper {width:1024px}
}

This is what I did in my application

NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];

Hopefully this simple answer will help somebody...

It is.

test.hpp:

class A {
public:
    static int a(int i);
};

test.cpp:

#include <iostream>

}

using namespace std;
int main() {
    cout << A::a(4) << endl;
}

They're not always inline, no, but the compiler can make them.

As explained here by Filip - http://www.filipekberg.se/2011/10/02/adding-properties-and-methods-to-an-expandoobject-dynamicly/

You can add a method too at runtime.

x.Add("Shout", new Action(() => { Console.WriteLine("Hellooo!!!"); }));
x.Shout();

No, you're not on the right track. A good rule of thumb is: make everything as private as possible. This makes your class more encapsulated, and allows for changing the internals of the class without affecting the code using your class.

If you design your class to be inheritable, then carefully choose what may be overridden and accessible from subclasses, and make that protected (and final, talking of Java, if you want to make it accessible but not overridable). But be aware that, as soon as you accept to have subclasses of your class, and there is a protected field or method, this field or method is part of the public API of the class, and may not be changed later without breaking subclasses.

A class that is not intended to be inherited should be made final (in Java). You might relax some access rules (private to protected, final to non-final) for the sake of unit-testing, but then document it, and make it clear that although the method is protected, it's not supposed to be overridden.

For those of you who are using the Data Binding Library, to get the root of the current activity, simply use:

View rootView = dataBinding.getRoot();

And for Kotlin users, it's even simpler:

val rootView = dataBinding.root

Problem: Even I was facing the problem where we were sending '£' with some string in POST request to CRM System, but when we were doing the GET call from CRM , it was returning '£' with some string content. So what we have analysed is that '£' was getting converted to '£'.

Analysis: The glitch which we have found after doing research is that in POST call we have set HttpWebRequest ContentType as "text/xml" while in GET Call it was "text/xml; charset:utf-8".

Solution: So as the part of solution we have included the charset:utf-8 in POST request and it works.

Regression means continuous variable, Linear means there is linear relation between y and x. Ex= You are trying to predict salary from no of years of experience. So here salary is independent variable(y) and yrs of experience is dependent variable(x). y=b0+ b1*x1 We are trying to find optimum value of constant b0 and b1 which will give us best fitting line for your observation data. It is a equation of line which gives continuous value from x=0 to very large value. This line is called Linear regression model.

Logistic regression is type of classification technique. Dnt be misled by term regression. Here we predict whether y=0 or 1.

Here we first need to find p(y=1) (wprobability of y=1) given x from formuale below.

Ex=we can make classification of tumour having more than 50% chance of having cancer as 1 and tumour having less than 50% chance of having cancer as 0.

Here red point will be predicted as 0 whereas green point will be predicted as 1.

you can put

getchar();

before the return from the main function. That will wait for a character input before exiting the program.

Alternatively you could run your program from a command line and the output would be visible.

you can turn off the warning message as explained in the other answers or you can understand what's happening and fix it.

As of MySQL 5.7.5, the default SQL mode includes ONLY_FULL_GROUP_BY which means when you are grouping rows and then selecting something out of that groups, you need to explicitly say which row should that selection be made from.

Mysql needs to know which row in the group you're looking for, which gives you two options

• You can also add the column you want to the group statement group by rect.color, rect.value which can be what you want in some cases otherwise would return duplicate results with the same color which you may not want
• you could also use aggregate functions of mysql to indicate which row you are looking for inside the groups like AVG() MIN() MAX() complete list
• AND finally you can use ANY_VALUE() if you are sure that all the results inside the group are the same. doc

At my last job I went a little deeper in the enum version:

public enum Messages {
    @Error
    @Text("You can''t put a {0} in a {1}")
    XYZ00001_CONTAINMENT_NOT_ALLOWED,
    ...
}

@Error, @Info, @Warning are retained in the class file and are available at runtime. (We had a couple of other annotations to help describe message delivery as well)

@Text is a compile-time annotation.

I wrote an annotation processor for this that did the following:

• Verify that there are no duplicate message numbers (the part before the first underscore)
• Syntax-check the message text
• Generate a messages.properties file that contains the text, keyed by the enum value.

I wrote a few utility routines that helped log errors, wrap them as exceptions (if desired) and so forth.

I'm trying to get them to let me open-source it... -- Scott

The Address property of a cell can get this for you:

MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)

returns A1.

The other way around can be done with the Row and Column property of Range:

MsgBox Range("A1").Row & ", " & Range("A1").Column

returns 1,1.

If you need to duplicate more than a few redirects, you might consider using a map:

# map is outside of server block
map $uri $redirect_uri {
    ~^/issue1/?$    http://example.com/shop/issues/custom_isse_name1;
    ~^/issue2/?$    http://example.com/shop/issues/custom_isse_name2;
    ~^/issue3/?$    http://example.com/shop/issues/custom_isse_name3;
    # ... or put these in an included file
}

location / {
    try_files $uri $uri/ @redirect-map;
}

location @redirect-map {
    if ($redirect_uri) {  # redirect if the variable is defined
        return 301 $redirect_uri;
    }
}

Column(children: <Widget>[
   Container(margin: EdgeInsets.only(top:12, child: yourWidget)),
   Container(margin: EdgeInsets.only(top:12, child: yourWidget))
]);

I feel like I should add my answer to this because it took me quite long to make this work:

This answer is for you if:

• you do not want to edit your original data
• if you need expressions (bquote) in your labels and
• if you want the flexibility of a separate labelling name-vector

I basically put the labels in a named vector so labels would not get confused or switched. The labeller expression could probably be simpler, but this at least works (improvements are very welcome). Note the ` (back quotes) to protect the facet-factor.

n <- 10
x <- seq(0, 300, length.out = n)

# I have my data in a "long" format
my_data <- data.frame(
  Type = as.factor(c(rep('dl/l', n), rep('alpha', n))),
  T = c(x, x),
  Value = c(x*0.1, sqrt(x))
)

# the label names as a named vector
type_names <- c(
  `nonsense` = "this is just here because it looks good",
  `dl/l` = Linear~Expansion~~Delta*L/L[Ref]~"="~"[%]", # bquote expression
  `alpha` = Linear~Expansion~Coefficient~~alpha~"="~"[1/K]"
  )


ggplot() + 
  geom_point(data = my_data, mapping = aes(T, Value)) + 
  facet_wrap(. ~ Type, scales="free_y", 
             labeller = label_bquote(.(as.expression(
               eval(parse(text = paste0('type_names', '$`', Type, '`')))
               )))) +
  labs(x="Temperature [K]", y="", colour = "") +
  theme(legend.position = 'none')

This works for me

dataGridView1.Rows[rowIndex].Cells[columnIndex].Style.BackColor = Color.Red;

Whenever we are trying to connect to URL,

if server at the other site is running on https protocol and is mandating that we should communicate via information provided in certificate then we have following option:

1) ask for the certificate(download the certificate), import this certificate in trustore. Default trustore java uses can be found in \Java\jdk1.6.0_29\jre\lib\security\cacerts, then if we retry to connect to the URL connection would be accepted.

2) In normal business cases, we might be connecting to internal URLS in organizations and we know that they are correct. In such cases, you trust that it is the correct URL, In such cases above, code can be used which will not mandate to store the certificate to connect to particular URL.

for the point no 2 we have to follow below steps :

1) write below method which sets HostnameVerifier for HttpsURLConnection which returns true for all cases meaning we are trusting the trustStore.

  // trusting all certificate 
 public void doTrustToCertificates() throws Exception {
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    public X509Certificate[] getAcceptedIssuers() {
                        return null;
                    }

                    public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
                        return;
                    }

                    public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {
                        return;
                    }
                }
        };

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HostnameVerifier hv = new HostnameVerifier() {
            public boolean verify(String urlHostName, SSLSession session) {
                if (!urlHostName.equalsIgnoreCase(session.getPeerHost())) {
                    System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
                }
                return true;
            }
        };
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
    }

2) write below method, which calls doTrustToCertificates before trying to connect to URL

    // connecting to URL
    public void connectToUrl(){
     doTrustToCertificates();//  
     URL url = new URL("https://www.example.com");
     HttpURLConnection conn = (HttpURLConnection)url.openConnection(); 
     System.out.println("ResponseCode ="+conn.getResponseCode());
   }

This call will return response code = 200 means connection is successful.

For more detail and sample example you can refer to URL.

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE

This error is most often encountered when attempting to reference an array value with a quoted key for interpolation inside a double-quoted string when the entire complex variable construct is not enclosed in {}.

The error case:

This will result in Unexpected T_ENCAPSED_AND_WHITESPACE:

echo "This is a double-quoted string with a quoted array key in $array['key']";
//---------------------------------------------------------------------^^^^^

Possible fixes:

In a double-quoted string, PHP will permit array key strings to be used unquoted, and will not issue an E_NOTICE. So the above could be written as:

echo "This is a double-quoted string with an un-quoted array key in $array[key]";
//------------------------------------------------------------------------^^^^^

The entire complex array variable and key(s) can be enclosed in {}, in which case they should be quoted to avoid an E_NOTICE. The PHP documentation recommends this syntax for complex variables.

echo "This is a double-quoted string with a quoted array key in {$array['key']}";
//--------------------------------------------------------------^^^^^^^^^^^^^^^
// Or a complex array property of an object:
echo "This is a a double-quoted string with a complex {$object->property->array['key']}";

Of course, the alternative to any of the above is to concatenate the array variable in instead of interpolating it:

echo "This is a double-quoted string with an array variable". $array['key'] . " concatenated inside.";
//----------------------------------------------------------^^^^^^^^^^^^^^^^^^^^^

For reference, see the section on Variable Parsing in the PHP Strings manual page

I think that you should try replacing php7.3-curl with api.hostip.info/?ip=$ip&position=true . Hope this helps

To elaborate on @Marc B's answer,

$ passwd
$ while [ $? -ne 0 ]; do !!; done

Is nice way of doing the same thing that's not command specific.

I am part of a team investigating the use of Evolutionary Computation (EC) to automatically fix bugs in existing programs. We have successfully repaired a number of real bugs in real world software projects (see this project's homepage).

We have two applications of this EC repair technique.

• The first (code and reproduction information available through the project page) evolves the abstract syntax trees parsed from existing C programs and is implemented in Ocaml using our own custom EC engine.

• The second (code and reproduction information available through the project page), my personal contribution to the project, evolves the x86 assembly or Java byte code compiled from programs written in a number of programming languages. This application is implemented in Clojure and also uses its own custom built EC engine.

One nice aspect of Evolutionary Computation is the simplicity of the technique makes it possible to write your own custom implementations without too much difficulty. For a good freely available introductory text on Genetic Programming see the Field Guide to Genetic Programming.

If the WAMP icon is Orange then one of the services has not started.

In your case it looks like MySQL has not started as you are getting the message that indicates there is no server running and therefore listening for requests.

Look at the mysql log and if that tells you nothing look at the Windows event log, in the Windows -> Applications section. Error messages in there are pretty good at identifying the cause of MySQL failing to start.

Sometimes this is caused by a my.ini file from another install being picked up by WAMPServers MySQL, normally in the \windows or \windows\system32 folders. Do a search for 'my.ini' and 'my.cnf' and if you find one of these anywhere outside of the \wamp.... folder structure then delete it, or at least rename it so it wont be found. Then restart the MySQL service.

Android Supports SSL implementation by default except for Android N (API level 24) and below Android 5.1 (API level 22)
I was getting the error when making the API call below API level 22 devices after implementing SSL at the server side; that was while creating OkHttpClient client object, and fixed by adding connectionSpecs() method OkHttpClient.Builder class.

the error received was

response failure: javax.net.ssl.SSLException: SSL handshake aborted: ssl=0xb8882c00: I/O error during system call, Connection reset by peer

so I fixed this by added the check like

if ( Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
            // Do something for below api level 22
            List<ConnectionSpec> specsList = getSpecsBelowLollipopMR1(okb);
            if (specsList != null) {
                okb.connectionSpecs(specsList);
            }
        }

Also for the Android N (API level 24); I was getting the error while making the HTTP call like

HTTP FAILED: javax.net.ssl.SSLHandshakeException: Handshake failed

and this is fixed by adding the check for Android 7 particularly, like

if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.N){
            // Do something for naugat ; 7
            okb.connectionSpecs(Collections.singletonList(getSpec()));
        }

So my final OkHttpClient object will be like:

         OkHttpClient client
         HttpLoggingInterceptor httpLoggingInterceptor2 = new
         HttpLoggingInterceptor();
         httpLoggingInterceptor2.setLevel(HttpLoggingInterceptor.Level.BODY);

         OkHttpClient.Builder okb = new OkHttpClient.Builder()
                 .addInterceptor(httpLoggingInterceptor2)
               .addInterceptor(new Interceptor() {
                     @Override
                     public Response intercept(Chain chain) throws IOException {
                         Request request = chain.request();
                         Request request2 = request.newBuilder().addHeader(AUTH_KEYWORD, AUTH_TYPE_JW + " " + password).build();
                         return chain.proceed(request2);
                     }
                 }).connectTimeout(30, TimeUnit.SECONDS)
                 .writeTimeout(30, TimeUnit.SECONDS)
                 .readTimeout(30, TimeUnit.SECONDS);

         if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.N){
             // Do something for naugat ; 7
             okb.connectionSpecs(Collections.singletonList(getSpec()));
         }

         if ( Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
             List<ConnectionSpec> specsList = getSpecsBelowLollipopMR1(okb);
             if (specsList != null) {
                 okb.connectionSpecs(specsList);
             }
         }

         //init client
         client = okb.build();

getSpecsBelowLollipopMR1 function be like,

   private List<ConnectionSpec> getSpecsBelowLollipopMR1(OkHttpClient.Builder okb) {

        try {

            SSLContext sc = SSLContext.getInstance("TLSv1.2");
            sc.init(null, null, null);
            okb.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));

            ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                    .tlsVersions(TlsVersion.TLS_1_2)
                    .build();

            List<ConnectionSpec> specs = new ArrayList<>();
            specs.add(cs);
            specs.add(ConnectionSpec.COMPATIBLE_TLS);

            return specs;

        } catch (Exception exc) {
            Timber.e("OkHttpTLSCompat Error while setting TLS 1.2"+ exc);

            return null;
        }
    }

If you round 8.8333333333339 to 2 decimals, the correct answer is 8.83, not 8.84. The reason you got 8.83000000001 is because 8.83 is a number that cannot be correctly reprecented in binary, and it gives you the closest one. If you want to print it without all the zeros, do as VGE says:

print "%.2f" % 8.833333333339   #(Replace number with the variable?)

As of TypeScript 3.7 you can use nullish coalescing operator ??. You can think of this feature as a way to “fall back” to a default value when dealing with null or undefined

let name1:string = person.name ?? '';

The ?? operator can replace uses of || when trying to use a default value and can be used when dealing with booleans, numbers, etc. where || cannot be used.

As of TypeScript 4 you can use ??= assignment operator as a ??= b which is an alternative to a = a ?? b;

Swift uses the same cocoa-touch API. You can call all the same methods, but they will use Swift's syntax. In this example you can do something like this:

self.simpleLabel.text = "message"

Note the setText method isn't available. Setting the label's text with = will automatically call the setter in swift.

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

From the command line, it's simply:

printf "compute sha1" | openssl sha1

You can invoke the library like this:

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

int main()
{
    unsigned char ibuf[] = "compute sha1";
    unsigned char obuf[20];

    SHA1(ibuf, strlen(ibuf), obuf);

    int i;
    for (i = 0; i < 20; i++) {
        printf("%02x ", obuf[i]);
    }
    printf("\n");

    return 0;
}

NullPointerException is a run-time exception which is not recommended to catch it, but instead avoid it:

if(someVariable != null) someVariable.doSomething();
else
{
    // do something else
}

That what manual says about setOnClickListener method is:

public void setOnClickListener (View.OnClickListener l)

Added in API level 1 Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.

Parameters

l View.OnClickListener: The callback that will run

And normally you have to use it like this

public class ExampleActivity extends Activity implements OnClickListener {
    protected void onCreate(Bundle savedValues) {
        ...
        Button button = (Button)findViewById(R.id.corky);
        button.setOnClickListener(this);
    }

    // Implement the OnClickListener callback
    public void onClick(View v) {
      // do something when the button is clicked
    }
    ...
}

Take a look at this lesson as well Building a Simple Calculator using Android Studio.

function cool(d)_x000D_
{_x000D_
    alert(d.value.length);_x000D_
}

<input type="text" value="" onblur="cool(this)">

It will return the length of string

Instead of blur use keydown event.

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:colorPrimary">#00397F</item>
    <item name="android:textColorPrimary">#22397F</item>
    <item name="android:colorAccent">#00397F</item>
    <item name="colorPrimaryDark">#22397F</item>
</style>

The color of the buttons and other text can also be changed using appcompat :

Look for any DDL operation in the script. Maybe the user does not have access rights to run changes.

In my case it was SET IDENTITY_INSERT tblTableName ON

You can either add db_ddladmin for the whole database or for just the table to solve this issue (or change the script)

-- give the non-ddladmin user INSERT/SELECT as well as ALTER:
GRANT ALTER, INSERT, SELECT ON dbo.tblTableName TO user_name;

Here's a variation, using the version of fs that uses promises:

const fs = require('fs');

await fs.promises.writeFile('../data/phraseFreqs.json', JSON.stringify(output)); // UTF-8 is default

Typescript Importer does do the job for me

https://marketplace.visualstudio.com/items?itemName=pmneo.tsimporter

It automatically searches for typescript definitions inside your workspace and when you press enter it'll import it.

In my case laravel 4.2 delete all rows ,but not truncate table

DB::table('your_table')->delete();

sp_help will give you a whole bunch of information about a table including the columns, keys and constraints. For example, running

exec sp_help 'Address' 

will give you information about Address.

Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.

In project -> Add Component -> Windows Form and select a form

Add some label and buttons.

Initialize the value in constructor and call it from anywhere.

public class form1:System.Windows.Forms.Form
{
    public form1()
    {
    }

    public form1(string message,string buttonText1,string buttonText2)
    {
       lblMessage.Text = message;
       button1.Text = buttonText1;
       button2.Text = buttonText2;
    }
}

// Write code for button1 and button2 's click event in order to call 
// from any where in your current project.

// Calling

Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();

#Forwarding Pattern => the best practice on JS overloading Forward to another function which name is built from the 3rd & 4th points :

3. Using number of arguments
4. Checking types of arguments

window['foo_'+arguments.length+'_'+Array.from(arguments).map((arg)=>typeof arg).join('_')](...arguments)

#Application on your case :

 function foo(...args){
          return window['foo_' + args.length+'_'+Array.from(args).map((arg)=>typeof arg).join('_')](...args);

  }
   //------Assuming that `x` , `y` and `z` are String when calling `foo` .

This is the best answer. Shorthand (background) is for reset and DRY (combine with longhand).

Exception code 0xc0000005 is an Access Violation. An AV at fault offset 0x00000000 means that something in your service's code is accessing a nil pointer. You will just have to debug the service while it is running to find out what it is accessing. If you cannot run it inside a debugger, then at least install a third-party exception logger framework, such as EurekaLog or MadExcept, to find out what your service was doing at the time of the AV.

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

I had same problem with UnicodeDecodeError and i solved it with this line. Don't know if is the best way but it worked for me.

str = str.decode('unicode_escape').encode('utf-8')

With Oracle 12c (June 2013), you are able to use it like the following.

SELECT * FROM   MYTABLE
--ORDER BY COLUMNNAME -OPTIONAL          
OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY

In class do like this

@RequestMapping(value = "/saveData", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<Boolean> saveData(
    HttpServletResponse response,
    Bean beanName
) throws MyException {
    return new ResponseEntity<Boolean>(uiRequestProcessor.saveData(a), HttpStatus.OK);
}

In page do like this:

<form enctype="multipart/form-data" action="<%=request.getContextPath()%>/saveData" method="post" name="saveForm" id="saveForm">
<input type="text" value="${beanName.userName }" id="username" name="userName" />

Nano is 10^-9 and milli 10^-3. Hence, we can use the three first characters of nanoseconds to get the milliseconds:

date +%s%3N

From man date:

%N nanoseconds (000000000..999999999)

%s seconds since 1970-01-01 00:00:00 UTC

If you use eclipse, maybe PyUML. Haven't used it, though.

Update for everybody coming to check why tensorflow.keras is not visible in PyCharm.

Starting from TensorFlow 2.0, only PyCharm versions > 2019.3 are able to recognise tensorflow and keras inside tensorflow (tensorflow.keras) properly.

Also, it is recommended(by Francois Chollet) that everybody switches to tensorflow.keras in place of plain keras.

You have selected correct approach. You have to extend the class with TextWatcher and override afterTextChanged(),beforeTextChanged(), onTextChanged().

You have to write your desired logic in afterTextChanged() method to achieve functionality needed by you.

You can just say

callback();

Alternately you can use the call method if you want to adjust the value of this within the callback.

callback.call( newValueForThis);

Inside the function this would be whatever newValueForThis is.

I needed to generate mongodb ids on client side.

After digging into the mongodb source code i found they generate ObjectIDs using npm bson lib.

If ever you need only to generate an ObjectID without installing the whole mongodb / mongoose package, you can import the lighter bson library :

const bson = require('bson');
new bson.ObjectId(); // 5cabe64dcf0d4447fa60f5e2

Note: There is also an npm project named bson-objectid being even lighter

None of the answers offered so far performs the deletion in place in O(n) on the length of the list for an arbitrary number of indices to delete, so here's my version:

def multi_delete(the_list, indices):
    assert type(indices) in {set, frozenset}, "indices must be a set or frozenset"
    offset = 0
    for i in range(len(the_list)):
        if i in indices:
            offset += 1
        elif offset:
            the_list[i - offset] = the_list[i]
    if offset:
        del the_list[-offset:]

# Example:
a = [0, 1, 2, 3, 4, 5, 6, 7]
multi_delete(a, {1, 2, 4, 6, 7})
print(a)  # prints [0, 3, 5]

It appears you could use a list instead of a tuple. This becomes more important I think when you are grabbing attributes instead of 'magic indexes' of a list/tuple.

In my case I wanted to sort by multiple attributes of a class, where the incoming keys were strings. I needed different sorting in different places, and I wanted a common default sort for the parent class that clients were interacting with; only having to override the 'sorting keys' when I really 'needed to', but also in a way that I could store them as lists that the class could share

So first I defined a helper method

def attr_sort(self, attrs=['someAttributeString']:
  '''helper to sort by the attributes named by strings of attrs in order'''
  return lambda k: [ getattr(k, attr) for attr in attrs ]

then to use it

# would defined elsewhere but showing here for consiseness
self.SortListA = ['attrA', 'attrB']
self.SortListB = ['attrC', 'attrA']
records = .... #list of my objects to sort
records.sort(key=self.attr_sort(attrs=self.SortListA))
# perhaps later nearby or in another function
more_records = .... #another list
more_records.sort(key=self.attr_sort(attrs=self.SortListB))

This will use the generated lambda function sort the list by object.attrA and then object.attrB assuming object has a getter corresponding to the string names provided. And the second case would sort by object.attrC then object.attrA.

This also allows you to potentially expose outward sorting choices to be shared alike by a consumer, a unit test, or for them to perhaps tell you how they want sorting done for some operation in your api by only have to give you a list and not coupling them to your back end implementation.

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

I was able to handle that by simply overriding the method 'unsuccessfulAuthentication' in my filter. There, I send an error response to the client with the desired HTTP status code.

@Override
protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response,
        AuthenticationException failed) throws IOException, ServletException {

    if (failed.getCause() instanceof RecordNotFoundException) {
        response.sendError((HttpServletResponse.SC_NOT_FOUND), failed.getMessage());
    }
}

What you're trying to achieve is simple, and the way you're going about it isn't. Try this (Works fine for me) and save the file as a batch from your text editor. Trust me, it's easier.

start firefox.exe

As an alternative, I have a library that makes it easy to work with procs: https://www.nuget.org/packages/SprocMapper/

SqlServerAccess sqlAccess = new SqlServerAccess("your connection string");
    sqlAccess.Procedure()
         .AddSqlParameter("@FirstName", SqlDbType.VarChar, txtFirstName.Text)
         .AddSqlParameter("@FirstName", SqlDbType.VarChar, txtLastName.Text)
         .ExecuteNonQuery("StoredProcedureName");

This works fine for me in all browsers:

(inline style for simplicity...)

<label style="font-size:16px;">
    <input style="height:1em; width:1em;" type="radio">
    <span>Button One</span>
</label>

The size of both the radio button and text will change with the label's font-size.

In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325

Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.

Make sure that you have checked it to work properly with the IE version you specify.

If you update to Bootstrap 3 (BS3), they've exposed a lot of Javascript events that are nice to tie your desired functionality into. In BS3, this code will give all of your dropdown menus the animation effect you are looking for:

  // Add slideDown animation to Bootstrap dropdown when expanding.
  $('.dropdown').on('show.bs.dropdown', function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideDown();
  });

  // Add slideUp animation to Bootstrap dropdown when collapsing.
  $('.dropdown').on('hide.bs.dropdown', function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideUp();
  });

You can read about BS3 events here and specifically about the dropdown events here.

Arrays - It would always be better when we have to achieve faster fetching of results

Lists- Performs results on insertion and deletion since they can be done in O(1) and this also provides methods to add, fetch and delete data easily. Much easier to use.

But always remember that the fetching of data would be fast when the index position in array where the data is stored - is known.

This could be achieved well by sorting the array. Hence this increases the time to fetch the data (ie; storing the data + sorting the data + seek for the position where the data is found). Hence this increases additional latency to fetch the data from the array even they may be good at fetching the data sooner.

Hence this could be solved with trie data structure or ternary data structure. As discussed above the trie data structure would be very efficient in searching for the data the search for a particularly word can be done in O(1) magnitude. When time matters ie; if you have to search and retrieve data quickly you may go with trie data structure.

If you want your memory space to be consumed less and you wish to have a better performance then go with ternary data structure. Both these are suitable for storing huge number of strings (eg; like words contained in dictionary).

The one with the ORDER BY is going to be the slower one.

select * from table where random() < 0.01; goes record by record, and decides to randomly filter it or not. This is going to be O(N) because it only needs to check each record once.

select * from table order by random() limit 1000; is going to sort the entire table, then pick the first 1000. Aside from any voodoo magic behind the scenes, the order by is O(N * log N).

The downside to the random() < 0.01 one is that you'll get a variable number of output records.

Note, there is a better way to shuffling a set of data than sorting by random: The Fisher-Yates Shuffle, which runs in O(N). Implementing the shuffle in SQL sounds like quite the challenge, though.

After all this, I found a new easier method try this ..

It can join multiple photos together:

public static System.Drawing.Bitmap CombineBitmap(string[] files)
{
    //read all images into memory
    List<System.Drawing.Bitmap> images = new List<System.Drawing.Bitmap>();
    System.Drawing.Bitmap finalImage = null;

    try
    {
        int width = 0;
        int height = 0;

        foreach (string image in files)
        {
            //create a Bitmap from the file and add it to the list
            System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(image);

            //update the size of the final bitmap
            width += bitmap.Width;
            height = bitmap.Height > height ? bitmap.Height : height;

            images.Add(bitmap);
        }

        //create a bitmap to hold the combined image
        finalImage = new System.Drawing.Bitmap(width, height);

        //get a graphics object from the image so we can draw on it
        using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(finalImage))
        {
            //set background color
            g.Clear(System.Drawing.Color.Black);

            //go through each image and draw it on the final image
            int offset = 0;
            foreach (System.Drawing.Bitmap image in images)
            {
                g.DrawImage(image,
                  new System.Drawing.Rectangle(offset, 0, image.Width, image.Height));
                offset += image.Width;
            }
        }

        return finalImage;
    }
    catch (Exception ex)
    {
        if (finalImage != null)
            finalImage.Dispose();

        throw ex;
    }
    finally
    {
        //clean up memory
        foreach (System.Drawing.Bitmap image in images)
        {
            image.Dispose();
        }
    }
}

As far as how to use unwind segues in StoryBoard...

Step 1)

Go to the code for the view controller that you wish to unwind to and add this:

Objective-C

- (IBAction)unwindToViewControllerNameHere:(UIStoryboardSegue *)segue {
    //nothing goes here
}

Be sure to also declare this method in your .h file in Obj-C

Swift

@IBAction func unwindToViewControllerNameHere(segue: UIStoryboardSegue) {
    //nothing goes here
}

Step 2)

In storyboard, go to the view that you want to unwind from and simply drag a segue from your button or whatever up to the little orange "EXIT" icon at the top right of your source view.

There should now be an option to connect to "- unwindToViewControllerNameHere"

That's it, your segue will unwind when your button is tapped.

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

I think you mean SqlServer but on Oracle you have a hard limit how many IN elements you can specify: 1000.

Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :

• offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.

On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :

• clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.

ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:

• scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.

• Changing Values:
  • array_map cannot change the values inside input array(s) while array_walk can; in particular, array_map never changes its arguments.
• Array Keys Access:
  • array_map cannot operate with the array keys, array_walk can.
• Return Value:
  • array_map returns a new array, array_walk only returns true. Hence, if you don't want to create an array as a result of traversing one array, you should use array_walk.
• Iterating Multiple Arrays:
  • array_map also can receive an arbitrary number of arrays and it can iterate over them in parallel, while array_walk operates only on one.
• Passing Arbitrary Data to Callback:
  • array_walk can receive an extra arbitrary parameter to pass to the callback. This mostly irrelevant since PHP 5.3 (when anonymous functions were introduced).
• Length of Returned Array:
  • The resulting array of array_map has the same length as that of the largest input array; array_walk does not return an array but at the same time it cannot alter the number of elements of original array; array_filter picks only a subset of the elements of the array according to a filtering function. It does preserve the keys.

Example:

<pre>
<?php

$origarray1 = array(2.4, 2.6, 3.5);
$origarray2 = array(2.4, 2.6, 3.5);

print_r(array_map('floor', $origarray1)); // $origarray1 stays the same

// changes $origarray2
array_walk($origarray2, function (&$v, $k) { $v = floor($v); }); 
print_r($origarray2);

// this is a more proper use of array_walk
array_walk($origarray1, function ($v, $k) { echo "$k => $v", "\n"; });

// array_map accepts several arrays
print_r(
    array_map(function ($a, $b) { return $a * $b; }, $origarray1, $origarray2)
);

// select only elements that are > 2.5
print_r(
    array_filter($origarray1, function ($a) { return $a > 2.5; })
);

?>
</pre>

Result:

Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
0 => 2.4
1 => 2.6
2 => 3.5
Array
(
    [0] => 4.8
    [1] => 5.2
    [2] => 10.5
)

    [2] => 3.5
)

Can create a procedure also to create calendar table with timestmap different from day. If you want a table for each quarter

e.g.

2019-01-22 08:45:00
2019-01-22 09:00:00
2019-01-22 09:15:00
2019-01-22 09:30:00
2019-01-22 09:45:00
2019-01-22 10:00:00

you can use

CREATE DEFINER=`root`@`localhost` PROCEDURE `generate_calendar_table`()
BEGIN

select unix_timestamp('2014-01-01 00:00:00') into @startts;
select unix_timestamp('2025-01-01 00:00:00') into @endts;

if ( @startts < @endts ) then

    DROP TEMPORARY TABLE IF EXISTS calendar_table_tmp;

    CREATE TEMPORARY TABLE calendar_table_tmp (ts int, dt datetime); 

    WHILE ( @startts < @endts)
        DO 
        SET @startts = @startts + 900;
        INSERT calendar_table_tmp VALUES (@startts, from_unixtime(@startts));
    END WHILE;

END if;

END

and then manipulate through

select ts, dt from calendar_table_tmp;

that give you also ts

'1548143100', '2019-01-22 08:45:00'
'1548144000', '2019-01-22 09:00:00'
'1548144900', '2019-01-22 09:15:00'
'1548145800', '2019-01-22 09:30:00'
'1548146700', '2019-01-22 09:45:00'
'1548147600', '2019-01-22 10:00:00'

from here you can start to add other information such as

select ts, dt, weekday(dt) as wd from calendar_table_tmp;

or create a real table with create table statement

As per the javadoc for get(), it is the synonym for Navigate.to()

View javadoc screenshot below:

Javadoc for get() says it all -

Load a new web page in the current browser window. This is done using an HTTP GET operation, and the method will block until the load is complete. This will follow redirects issued either by the server or as a meta-redirect from within the returned HTML. Should a meta-redirect "rest" for any duration of time, it is best to wait until this timeout is over, since should the underlying page change whilst your test is executing the results of future calls against this interface will be against the freshly loaded page. Synonym for org.openqa.selenium.WebDriver.Navigation.to(String).

Don't post the data as an array. To bind to a list, the key/value pairs should be submitted with the same value for each key.

You should not need a form to do this. You just need a list of key/value pairs, which you can include in the call to $.post.

Update 2019

I tried easy_install at first but it doesn't install packages in a clean and intuitive way. Also when it comes time to remove packages it left a lot of artifacts that needed to be cleaned up.

sudo yum install epel-release
sudo yum install python34-pip
pip install package

Was the solution that worked for me, it installs "pip3" as pip on the system. It also uses standard rpm structure so it clean in its removal. I am not sure what process you would need to take if you want both python2 and python3 package manager on your system.

Using the link from Daniel, I made an extension to make it more usable:

//UITableViewController+Ext.m
- (void)hideEmptySeparators
{
    UIView *v = [[UIView alloc] initWithFrame:CGRectZero];
    v.backgroundColor = [UIColor clearColor];
    [self.tableView setTableFooterView:v];
    [v release];
}

After some testings, I found out that the size can be 0 and it works as well. So it doesn't add some kind of margin at the end of the table. So thanks wkw for this hack. I decided to post that here since I don't like redirect.

I don't think it's necessary to use semi-quotes around the variables, try:

curl -XPOST 'http://localhost/Service' -d "path=%2fxyz%2fpqr%2ftest%2f&fileName=1.doc"

%2f is the escape code for a /.

http://www.december.com/html/spec/esccodes.html

Also, do you need to specify a port? ( just checking :) )

These three keywords are also used in a completely different context to specify the visibility inheritance model.

This table gathers all of the possible combinations of the component declaration and inheritance model presenting the resulting access to the components when the subclass is completely defined.

The table above is interpreted in the following way (take a look at the first row):

if a component is declared as public and its class is inherited as public the resulting access is public.

An example:

 class Super {
    public:      int p;
    private:     int q;
    protected:   int r;
 };

 class Sub : private Super {};

 class Subsub : public Sub {};

The resulting access for variables p, q, r in class Subsub is none.

Another example:

class Super {
    private:     int x;
    protected:   int y;
    public:      int z;
 };
class Sub : protected Super {};

The resulting access for variables y, z in class Sub is protected and for variable x is none.

A more detailed example:

class Super {
private:
    int storage;
public:
    void put(int val) { storage = val;  }
    int  get(void)    { return storage; }
};
int main(void) {
    Super object;

    object.put(100);
    object.put(object.get());
    cout << object.get() << endl;
    return 0;
}

Now lets define a subclass:

class Sub : Super { };

int main(void) {
    Sub object;

    object.put(100);
    object.put(object.get());
    cout << object.get() << endl;
    return 0;
}

The defined class named Sub which is a subclass of class named Super or that Sub class is derived from the Super class. The Sub class introduces neither new variables nor new functions. Does it mean that any object of the Sub class inherits all the traits after the Super class being in fact a copy of a Super class’ objects?

No. It doesn’t.

If we compile the following code, we will get nothing but compilation errors saying that put and get methods are inaccessible. Why?

When we omit the visibility specifier, the compiler assumes that we are going to apply the so-called private inheritance. It means that all public superclass components turn into private access, private superclass components won't be accessible at all. It consequently means that you are not allowed to use the latter inside the subclass.

We have to inform the compiler that we want to preserve the previously used access policy.

class Sub : public Super { };

Don’t be misled: it doesn’t mean that private components of the Super class (like the storage variable) will turn into public ones in a somewhat magical way. Private components will remain private, public will remain public.

Objects of the Sub class may do "almost" the same things as their older siblings created from the Super class. "Almost" because the fact of being a subclass also means that the class lost access to the private components of the superclass. We cannot write a member function of the Sub class which would be able to directly manipulate the storage variable.

This is a very serious restriction. Is there any workaround?

Yes.

The third access level is called protected. The keyword protected means that the component marked with it behaves like a public one when used by any of the subclasses and looks like a private one to the rest of the world. -- This is true only for the publicly inherited classes (like the Super class in our example) --

class Super {
protected:
    int storage;
public:
    void put(int val) { storage = val;  }
    int  get(void)    { return storage; }
};

class Sub : public Super {
public:
    void print(void) {cout << "storage = " << storage;}
};

int main(void) {
    Sub object;

    object.put(100);
    object.put(object.get() + 1);
    object.print();
    return 0;
}

As you see in the example code we a new functionality to the Sub class and it does one important thing: it accesses the storage variable from the Super class.

It wouldn’t be possible if the variable was declared as private. In the main function scope the variable remains hidden anyway so if you write anything like:

object.storage = 0;

The compiler will inform you that it is an error: 'int Super::storage' is protected.

Finally, the last program will produce the following output:

storage = 101

It's just PHP, not HTML.

It parses all HTML fields with [] into an array.

So you can have

<input type="checkbox" name="food[]" value="apple" />
<input type="checkbox" name="food[]" value="pear" />

and when submitted, PHP will make $_POST['food'] an array, and you can access its elements like so:

echo $_POST['food'][0]; // would output first checkbox selected

or to see all values selected:

foreach( $_POST['food'] as $value ) {
    print $value;
}

Anyhow, don't think there is a specific name for it

I'd prefer using Pathname:

require 'pathname' # pathname is in stdlib
Pathname(ROOT_DIR) + project + 'App.config'

about << and + from ruby docs:

+: Returns a new String containing other_str concatenated to str

<<: Concatenates the given object to str. If the object is a Fixnum between 0 and 255, it is converted to a character before concatenation.

so difference is in what becomes to first operand (<< makes changes in place, + returns new string so it is memory heavier) and what will be if first operand is Fixnum (<< will add as if it was character with code equal to that number, + will raise error)

I'm doing conversion to hex string in a pretty large loop, so I tried several techniques in order to find the fastest one. My requirements were to have a fixed-length string as a result, and encode negative values properly (-1 => ff..f).

Simple .toString(16) didn't work for me since I needed negative values to be properly encoded. The following code is the quickest I've tested so far on 1-2 byte values (note that symbols defines the number of output symbols you want to get, that is for 4-byte integer it should be equal to 8):

var hex = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'];
function getHexRepresentation(num, symbols) {
    var result = '';
    while (symbols--) {
        result = hex[num & 0xF] + result;
        num >>= 4;
    }
    return result;
}

It performs faster than .toString(16) on 1-2 byte numbers and slower on larger numbers (when symbols >= 6), but still should outperform methods that encode negative values properly.

If you have main.s file. you can generate object file by GCC and also as

# gcc -c main.s
# as main.s -o main.o

check this link, it will help you learn some binutils of GCC http://www.thegeekstuff.com/2017/01/gnu-binutils-commands/

ALTER DATABASE name OWNER TO new_owner;

See the Postgresql manual's entry on this for more details.

function msort(arr){
    for(var i =0;i<arr.length;i++){
        for(var j= i+1;j<arr.length;j++){
            if(arr[i]>arr[j]){
                var swap = arr[i];
                arr[i] = arr[j];
                arr[j] = swap;
            }
        }
    }
return arr;
}

Immutable means that once the object is created, non of its members will change. String is immutable since you can not change its content. For example:

String s1 = "  abc  ";
String s2 = s1.trim();

In the code above, the string s1 did not change, another object (s2) was created using s1.

This works for me

:%s/^\s*$\n//gc

Inside MathMethod.Py.

def Add(a,b):
   return a+b 

def subtract(a,b):
  return a-b

Inside Main.Py

import MathMethod as MM 
  print(MM.Add(200,1000))

Output:1200

in jQuery you might target the Parent directly.

THIS IS USEFUL IF YOU DO NOT KNOW EXACTLY HOW MANY CHILDREN WILL BE ADDED DYNAMICALLY or IF YOU JUST CAN'T FIGURE OUT THEIR NUMBER.

var tWidth=0;

$('.children').each(function(i,e){
tWidth += $(e).width();

///Example: If the Children have a padding-left of 10px;..
//You could do instead:
tWidth += ($(e).width()+10);

})
$('#parent').css('width',tWidth);

This will let the parent grow horizontally as the children are beng added.

NOTE: This assumes that the '.children' have a width and Height Set

Hope that Helps.

Thanks for your suggestions, you got me on the right way !

Let's go for a complete explanation :

• By default AngularJS http get query returns an object

• So if you want to use @Ariel Array.prototype.chunk function you have first to transform object into an array.

• And then to use the chunk function IN YOUR CONTROLLER otherwise if used directly into ng-repeat, it will brings you to an infdig error. The final controller looks :

  // Initialize products to empty list
  $scope.products = [];
  
  // Load products from config file
  $resource("/json/shoppinglist.json").get(function (data_object)
  {
      // Transform object into array
      var data_array =[];
      for( var i in data_object ) {
          if (typeof data_object[i] === 'object' && data_object[i].hasOwnProperty("name")){
              data_array.push(data_object[i]);
          }
      }
      // Chunk Array and apply scope
      $scope.products = data_array.chunk(3);
  });
  

And HTML becomes :

<div class="row" ng-repeat="productrow in products">

    <div class="col-sm-4" ng-repeat="product in productrow">

On the other side, I decided to directly return an array [] instead of an object {} from my JSON file. This way, controller becomes (please note specific syntax isArray:true) :

    // Initialize products to empty list 
    $scope.products = [];

    // Load products from config file
    $resource("/json/shoppinglist.json").query({method:'GET', isArray:true}, function (data_array)
    {
        $scope.products = data_array.chunk(3);
    });

HTML stay the same as above.

OPTIMIZATION

Last question in suspense is : how to make it 100% AngularJS without extending javascript array with chunk function ... if some people are interested in showing us if ng-repeat-start and ng-repeat-end are the way to go ... I'm curious ;)

ANDREW'S SOLUTION

Thanks to @Andrew, we now know adding a bootstrap clearfix class every three (or whatever number) element corrects display problem from differents block's height.

So HTML becomes :

<div class="row">

    <div ng-repeat="product in products">

        <div ng-if="$index % 3 == 0" class="clearfix"></div>

        <div class="col-sm-4"> My product descrition with {{product.property}}

And your controller stays quite soft with removed chunck function :

// Initialize products to empty list 
        $scope.products = [];

        // Load products from config file
        $resource("/json/shoppinglist.json").query({method:'GET', isArray:true}, function (data_array)
        {
            //$scope.products = data_array.chunk(3);
            $scope.products = data_array;
        });

std::unique_ptr has no copy constructor. You create an instance and then ask the std::vector to copy that instance during initialisation.

error: deleted function 'std::unique_ptr<_Tp, _Tp_Deleter>::uniqu
e_ptr(const std::unique_ptr<_Tp, _Tp_Deleter>&) [with _Tp = int, _Tp_D
eleter = std::default_delete<int>, std::unique_ptr<_Tp, _Tp_Deleter> =
 std::unique_ptr<int>]'

The class satisfies the requirements of MoveConstructible and MoveAssignable, but not the requirements of either CopyConstructible or CopyAssignable.

The following works with the new emplace calls.

std::vector< std::unique_ptr< int > > vec;
vec.emplace_back( new int( 1984 ) );

See using unique_ptr with standard library containers for further reading.

Executing Linq queries can generate extra threads. When I try to execute code that uses Linq query collection in the immediate window it often refuses to run because not enough threads are available to the debugger.

As others have said, for threads to exit when they are finished is perfectly normal.

str is text representation in bytes, unicode is text representation in characters.

You decode text from bytes to unicode and encode a unicode into bytes with some encoding.

That is:

>>> 'abc'.decode('utf-8')  # str to unicode
u'abc'
>>> u'abc'.encode('utf-8') # unicode to str
'abc'

UPD Sep 2020: The answer was written when Python 2 was mostly used. In Python 3, str was renamed to bytes, and unicode was renamed to str.

>>> b'abc'.decode('utf-8') # bytes to str
'abc'
>>> 'abc'.encode('utf-8'). # str to bytes
b'abc'

Well $.each is a library construct, whereas for ... in is native js, which should be better

Your NewClass inherits from UIViewController. You declared signedIn in ViewController. If you want NewClass to be able to identify that variable it will have to be declared in a class that your NewClass inherits from.

A little bit easier and it looks exactly like the button in the form. Just use the input and wrap the anchor tag around it.

<a href="#"><input type="button" value="Button Text"></a>

You can use Date.before() or Date.after() or Date.equals() for date comparison.

Taken from here:

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateDiff {

    public static void main( String[] args )
    {
        compareDates("2017-01-13 00:00:00", "2017-01-14 00:00:00");// output will be Date1 is before Date2
        compareDates("2017-01-13 00:00:00", "2017-01-12 00:00:00");//output will be Date1 is after Date2
        compareDates("2017-01-13 00:00:00", "2017-01-13 10:20:30");//output will be Date1 is before Date2 because date2 is ahead of date 1 by 10:20:30 hours
        compareDates("2017-01-13 00:00:00", "2017-01-13 00:00:00");//output will be Date1 is equal Date2 because both date and time are equal
    }

    public static void compareDates(String d1,String d2)
    {
        try{
            // If you already have date objects then skip 1

            //1
            // Create 2 dates starts
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            Date date1 = sdf.parse(d1);
            Date date2 = sdf.parse(d2);

            System.out.println("Date1"+sdf.format(date1));
            System.out.println("Date2"+sdf.format(date2));System.out.println();

            // Create 2 dates ends
            //1

            // Date object is having 3 methods namely after,before and equals for comparing
            // after() will return true if and only if date1 is after date 2
            if(date1.after(date2)){
                System.out.println("Date1 is after Date2");
            }
            // before() will return true if and only if date1 is before date2
            if(date1.before(date2)){
                System.out.println("Date1 is before Date2");
            }

            //equals() returns true if both the dates are equal
            if(date1.equals(date2)){
                System.out.println("Date1 is equal Date2");
            }

            System.out.println();
        }
        catch(ParseException ex){
            ex.printStackTrace();
        }
    }

    public static void compareDates(Date date1,Date date2)
    {
        // if you already have date objects then skip 1
        //1

        //1

        //date object is having 3 methods namely after,before and equals for comparing
        //after() will return true if and only if date1 is after date 2
        if(date1.after(date2)){
            System.out.println("Date1 is after Date2");
        }

        //before() will return true if and only if date1 is before date2
        if(date1.before(date2)){
            System.out.println("Date1 is before Date2");
        }

        //equals() returns true if both the dates are equal
        if(date1.equals(date2)){
            System.out.println("Date1 is equal Date2");
        }

        System.out.println();
    }
}

Ok, this is best solution for me. Bootstrap includes mobile-first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. So this worked perfectly on every browser and device:

        <div class="row">
            <div class="col-lg-4"></div>
            <div class="col-lg-4">
                <div class="input-group">
                    <input type="text" class="form-control" /> 
                    <span class="input-group-btn">
                        <button class="btn btn-default" type="button">Go!</button>
                    </span>
                </div><!-- /input-group -->
            </div><!-- /.col-lg-4 -->
            <div class="col-lg-4"></div>
        </div><!-- /.row -->

It means 4 + 4 + 4 =12... so second div will be in the middle that way.

In the Developer Tools in Chrome, there is a bar along the top, called the Execution Context Selector (h/t felipe-sabino), just under the Elements, Network, Sources... tabs, that changes depending on the context of the current tab. When in the Console tab there is a dropdown in that bar that allows you to select the frame context in which the Console will operate. Select your frame in this drop down and you will find yourself in the appropriate frame context. :D

In the v-model the value of the property might not be a strict boolean value and the checkbox might not 'recognise' the value as checked/unchecked. There is a neat feature in VueJS to make the conversion to true or false:

<input

  v-model="toggle"
  true-value="yes"
  false-value="no"

I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh let's use imshow:

import numpy as np
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
              [5, 6, 7, 8],
              [9, 10, 11, 12],
              [13, 14, 15, 16]])  # added some commas and array creation code

fig = plt.figure(figsize=(6, 3.2))

ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')

cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()

The :: operator is called the scope-resolution operator and does just that, it resolves scope. So, by prefixing a type-name with this, it tells your compiler to look in the global namespace for the type.

Example:

int count = 0;

int main(void) {
  int count = 0;
  ::count = 1;  // set global count to 1
  count = 2;    // set local count to 2
  return 0;
}

I wrote this a long time ago (from years 1985-1992, with just a few tweaks since then), and just copy and paste the bits needed into each project.

You must call cfmakeraw on a tty obtained from tcgetattr. You cannot zero-out a struct termios, configure it, and then set the tty with tcsetattr. If you use the zero-out method, then you will experience unexplained intermittent failures, especially on the BSDs and OS X. "Unexplained intermittent failures" include hanging in read(3).

"Blocking" sets whether a read() on the port waits for the specified number of characters to arrive. Setting no blocking means that a read() returns however many characters are available without waiting for more, up to the buffer limit.

Addendum:

CMSPAR is needed only for choosing mark and space parity, which is uncommon. For most applications, it can be omitted. My header file /usr/include/bits/termios.h enables definition of CMSPAR only if the preprocessor symbol __USE_MISC is defined. That definition occurs (in features.h) with

#if defined _BSD_SOURCE || defined _SVID_SOURCE
 #define __USE_MISC     1
#endif

Since you are using features of ES6 (arrow functions), you may also simply use a for loop like this:

for(let child of [{0: [{'a':1,'b':2},{'c':3}]},{1:[]}]) {_x000D_
  console.log(child)_x000D_
}

I also faced the same issue, but my fault was that I was running "rails s" outside of my application directory. After opening the cmd, just go inside your application and run the commands from their, it worked for me.

Here is my code of custom UITableView subclass, which expand UITextView at the table cell, without reloading (and lost keyboard focus):

- (void)textViewDidChange:(UITextView *)textView {
    CGFloat textHeight = [textView sizeThatFits:CGSizeMake(self.width, MAXFLOAT)].height;
    // Check, if text height changed
    if (self.previousTextHeight != textHeight && self.previousTextHeight > 0) {
        [self beginUpdates];

        // Calculate difference in height
        CGFloat difference = textHeight - self.previousTextHeight;

        // Update currently editing cell's height
        CGRect editingCellFrame = self.editingCell.frame;
        editingCellFrame.size.height += difference;
        self.editingCell.frame = editingCellFrame;

        // Update UITableView contentSize
        self.contentSize = CGSizeMake(self.contentSize.width, self.contentSize.height + difference);

        // Scroll to bottom if cell is at the end of the table
        if (self.editingNoteInEndOfTable) {
            self.contentOffset = CGPointMake(self.contentOffset.x, self.contentOffset.y + difference);
        } else {
            // Update all next to editing cells
            NSInteger editingCellIndex = [self.visibleCells indexOfObject:self.editingCell];
            for (NSInteger i = editingCellIndex; i < self.visibleCells.count; i++) {
                UITableViewCell *cell = self.visibleCells[i];
                CGRect cellFrame = cell.frame;
                cellFrame.origin.y += difference;
                cell.frame = cellFrame;
            }
        }
        [self endUpdates];
    }
    self.previousTextHeight = textHeight;
}

For all who came here from google and are using an anchor element for firing the event, please make sure to void the click likewise:

<a  
href='javascript:void(0)'  
onclick='javascript:whatever causing the page to scroll to the top'  
></a>

<input data-ng-model="userInf.username"  class="span12 editEmail" type="text"  placeholder="[email protected]"  pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" required ng-disabled="true"/>

This is how ended up getting the current scroll position live from the view. All I am doing is using the on scroll event listener and the scrollEventThrottle. I am then passing it as an event to handle scroll function I made and updating my props.

 export default class Anim extends React.Component {
          constructor(props) {
             super(props);
             this.state = {
               yPos: 0,
             };
           }

        handleScroll(event){
            this.setState({
              yPos : event.nativeEvent.contentOffset.y,
            })
        }

        render() {
            return (
          <ScrollView onScroll={this.handleScroll.bind(this)} scrollEventThrottle={16} />
    )
    }
    }

Since I just ran in to this problem on a shared host and was unable to add the values to my .htaccess file I thought I'd share my solution.

I made an ini file with the values in it. Simple as that:

Make a file called ".user.ini" and add your values

upload_max_filesize = 150M
post_max_size = 150M

Boom, problem solved.

Give your body tag an overflow: scroll;

body {
    overflow: scroll;
}

or if you only want a vertical scrollbar use overflow-y

body {
    overflow-y: scroll;
}

There's a python module especially made for reading and writing to and from binary encoded data called 'struct'. Since versions of Python under 2.6 doesn't support str.format, a custom method needs to be used to create binary formatted strings.

import struct

# binary string
def bstr(n): # n in range 0-255
    return ''.join([str(n >> x & 1) for x in (7,6,5,4,3,2,1,0)])

# read file into an array of binary formatted strings.
def read_binary(path):
    f = open(path,'rb')
    binlist = []
    while True:
        bin = struct.unpack('B',f.read(1))[0] # B stands for unsigned char (8 bits)
        if not bin:
            break
        strBin = bstr(bin)
        binlist.append(strBin)
    return binlist

<input type="text" name="whatever" id="funkystyling" />

Here's the CSS for the image on the left:

#funkystyling {
    background: white url(/path/to/icon.png) left no-repeat;
    padding-left: 17px;
}

And here's the CSS for the image on the right:

#funkystyling {
    background: white url(/path/to/icon.png) right no-repeat;
    padding-right: 17px;
}

As mentioned by Dan Abramov

Do it right inside render

We actually use that approach with memoise one for any kind of proxying props to state calculations.

Our code looks this way

// ./decorators/memoized.js  
import memoizeOne from 'memoize-one';

export function memoized(target, key, descriptor) {
  descriptor.value = memoizeOne(descriptor.value);
  return descriptor;
}

// ./components/exampleComponent.js
import React from 'react';
import { memoized } from 'src/decorators';

class ExampleComponent extends React.Component {
  buildValuesFromProps() {
    const {
      watchedProp1,
      watchedProp2,
      watchedProp3,
      watchedProp4,
      watchedProp5,
    } = this.props
    return {
      value1: buildValue1(watchedProp1, watchedProp2),
      value2: buildValue2(watchedProp1, watchedProp3, watchedProp5),
      value3: buildValue3(watchedProp3, watchedProp4, watchedProp5),
    }
  }

  @memoized
  buildValue1(watchedProp1, watchedProp2) {
    return ...;
  }

  @memoized
  buildValue2(watchedProp1, watchedProp3, watchedProp5) {
    return ...;
  }

  @memoized
  buildValue3(watchedProp3, watchedProp4, watchedProp5) {
    return ...;
  }

  render() {
    const {
      value1,
      value2,
      value3
    } = this.buildValuesFromProps();

    return (
      <div>
        <Component1 value={value1}>
        <Component2 value={value2}>
        <Component3 value={value3}>
      </div>
    );
  }
}

The benefits of it are that you don't need to code tons of comparison boilerplate inside getDerivedStateFromProps or componentWillReceiveProps and you can skip copy-paste initialization inside a constructor.

NOTE:

This approach is used only for proxying the props to state, in case you have some inner state logic it still needs to be handled in component lifecycles.

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

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

Should be

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

Use Enumerable.Contains function:

var result =
    !(compareString.Contains(firstString) || compareString.Contains(secondString));

1.- Upcasting.

Doing an upcasting, you define a tag of some type, that points to an object of a subtype (Type and subtype may be called class and subclass, if you feel more comfortable...).

Animal animalCat = new Cat();

What means that such tag, animalCat, will have the functionality (the methods) of type Animal only, because we've declared it as type Animal, not as type Cat.

We are allowed to do that in a "natural/implicit/automatic" way, at compile-time or at a run-time, mainly because Cat inherits some of its functionality from Animal; for example, move(). (At least, cat is an animal, isn't it?)

2.- Downcasting.

But, what would happen if we need to get the functionality of Cat, from our type Animal tag?.

As we have created the animalCat tag pointing to a Cat object, we need a way to call the Cat object methods, from our animalCat tag in a some smart pretty way.

Such procedure is what we call Downcasting, and we can do it only at the run-time.

Time for some code:

public class Animal {
    public String move() {
        return "Going to somewhere";
    }
}

public class Cat extends Animal{
    public String makeNoise() {
        return "Meow!";
    }   
}

public class Test {

    public static void main(String[] args) {
        
    //1.- Upcasting 
    //  __Type_____tag________object
        Animal animalCat = new Cat();
    //Some animal movement
        System.out.println(animalCat.move());
        //prints "Going to somewhere"
        
    //2.- Downcasting   
    //Now you wanna make some Animal noise.
        //First of all: type Animal hasn't any makeNoise() functionality.
        //But Cat can do it!. I wanna be an Animal Cat now!!
        
        //___________________Downcast__tag_____ Cat's method
        String animalNoise = ( (Cat) animalCat ).makeNoise();
        
        System.out.println(animalNoise);
        //Prints "Meow!", as cats usually done.
        
    //3.- An Animal may be a Cat, but a Dog or a Rhinoceros too.
        //All of them have their own noises and own functionalities.
        //Uncomment below and read the error in the console:
        
    //  __Type_____tag________object
        //Cat catAnimal = new Animal();
        
    }

}

What you have is correct, but this is more consice:

One case which hasn't been covered is how to handle cancellation inside of an async method. Take for example a simple case where you need to upload some data to a service get it to calculate something and then return some results.

public async Task<Results> ProcessDataAsync(MyData data)
{
    var client = await GetClientAsync();
    await client.UploadDataAsync(data);
    await client.CalculateAsync();
    return await client.GetResultsAsync();
}

If you want to support cancellation then the easiest way would be to pass in a token and check if it has been cancelled between each async method call (or using ContinueWith). If they are very long running calls though you could be waiting a while to cancel. I created a little helper method to instead fail as soon as canceled.

public static class TaskExtensions
{
    public static async Task<T> WaitOrCancel<T>(this Task<T> task, CancellationToken token)
    {
        token.ThrowIfCancellationRequested();
        await Task.WhenAny(task, token.WhenCanceled());
        token.ThrowIfCancellationRequested();

        return await task;
    }

    public static Task WhenCanceled(this CancellationToken cancellationToken)
    {
        var tcs = new TaskCompletionSource<bool>();
        cancellationToken.Register(s => ((TaskCompletionSource<bool>)s).SetResult(true), tcs);
        return tcs.Task;
    }
}

So to use it then just add .WaitOrCancel(token) to any async call:

public async Task<Results> ProcessDataAsync(MyData data, CancellationToken token)
{
    Client client;
    try
    {
        client = await GetClientAsync().WaitOrCancel(token);
        await client.UploadDataAsync(data).WaitOrCancel(token);
        await client.CalculateAsync().WaitOrCancel(token);
        return await client.GetResultsAsync().WaitOrCancel(token);
    }
    catch (OperationCanceledException)
    {
        if (client != null)
            await client.CancelAsync();
        throw;
    }
}

Note that this will not stop the Task you were waiting for and it will continue running. You'll need to use a different mechanism to stop it, such as the CancelAsync call in the example, or better yet pass in the same CancellationToken to the Task so that it can handle the cancellation eventually. Trying to abort the thread isn't recommended.

You can use ~ (tilde operator) to exclude the rows sampled using df.sample(), letting pandas alone handle sampling and filtering of indexes, to obtain two sets.

train_df = df.sample(frac=0.8, random_state=100)
test_df = df[~df.index.isin(train_df.index)]

You can't just use a percentage width for the div? Setting the width to 50% will make it 50% as wide as the window (assuming there is no parent element with a width assigned to it).

You can try doing:

String myResource = IOUtils.toString(this.getClass().getResourceAsStream("yourfile.xml")).replace("\n","");

This code work in IE7 and Chrome:

var hiddenInput = document.createElement("input");
    hiddenInput.setAttribute("id", "uniqueIdentifier");
    hiddenInput.setAttribute("type", "hidden");                     
    hiddenInput.setAttribute("value", 'ID');
    hiddenInput.setAttribute("class", "ListItem");

$('body').append(hiddenInput);

Maybe problem somewhere else ?

To run your_command as a subprocess in a different directory, pass cwd parameter, as suggested in @wim's answer:

import subprocess

subprocess.check_call(['your_command', 'arg 1', 'arg 2'], cwd=working_dir)

A child process can't change its parent's working directory (normally). Running cd .. in a child shell process using subprocess won't change your parent Python script's working directory i.e., the code example in @glglgl's answer is wrong. cd is a shell builtin (not a separate executable), it can change the directory only in the same process.

You are using a forward declaration for the type MainWindowClass. That's fine, but it also means that you can only declare a pointer or reference to that type. Otherwise the compiler has no idea how to allocate the parent object as it doesn't know the size of the forward declared type (or if it actually has a parameterless constructor, etc.)

So, you either want:

// forward declaration, details unknown
class A;

class B {
  A *a;  // pointer to A, ok
};

Or, if you can't use a pointer or reference....

// declaration of A
#include "A.h"

class B {
  A a;  // ok, declaration of A is known
};

At some point, the compiler needs to know the details of A.

If you are only storing a pointer to A then it doesn't need those details when you declare B. It needs them at some point (whenever you actually dereference the pointer to A), which will likely be in the implementation file, where you will need to include the header which contains the declaration of the class A.

// B.h
// header file

// forward declaration, details unknown
class A;

class B {
public: 
    void foo();
private:
  A *a;  // pointer to A, ok
};

// B.cpp
// implementation file

#include "B.h"
#include "A.h"  // declaration of A

B::foo() {
    // here we need to know the declaration of A
    a->whatever();
}

You can make an Embedded class, which contains your two keys, and then have a reference to that class as EmbeddedId in your Entity.

You would need the @EmbeddedId and @Embeddable annotations.

@Entity
public class YourEntity {
    @EmbeddedId
    private MyKey myKey;

    @Column(name = "ColumnA")
    private String columnA;

    /** Your getters and setters **/
}

@Embeddable
public class MyKey implements Serializable {

    @Column(name = "Id", nullable = false)
    private int id;

    @Column(name = "Version", nullable = false)
    private int version;

    /** getters and setters **/
}

Another way to achieve this task is to use @IdClass annotation, and place both your id in that IdClass. Now you can use normal @Id annotation on both the attributes

@Entity
@IdClass(MyKey.class)
public class YourEntity {
   @Id
   private int id;
   @Id
   private int version;

}

public class MyKey implements Serializable {
   private int id;
   private int version;
}

Please refer to this for the example .The main point is to use the groupProperty() , and the related aggregate functions provided by the Projections class.

For example :

SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name

Its equivalent criteria object is :

List result = session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).list();

I would like to update the answers above to 2018 and say to use both VisualVM and Eclipse MAT.

How to use:

VisualVM is used for live monitoring and dump heap. You can also analyze the heap dumps there with great power, however MAT have more capabilities (such as automatic analysis to find leaks) and therefore, I read the VisualVM dump output (.hprof file) into MAT.

Get VisualVM:

Download VisualVM here: https://visualvm.github.io/

You also need to download the plugin for Intellij:

Then you'll see in intellij another 2 new orange icons:

Once you run your app with an orange one, in VisualVM you'll see your process on the left, and data on the right. Sit some time and learn this tool, it is very powerful:

Get Eclipse's Memory Analysis Tool (MAT) as a standalone:

Download here: https://www.eclipse.org/mat/downloads.php

And this is how it looks:

Hope it helps!

Okay I have got it working, hope this information is useful.

1. First of all I now realize that not only do self-extracting zip start extracting with doubleclick, but they require no extraction application to be installed on the users computer because the extractor code is in the archive itself. This means that you will get a different user experience depending on what you application you use to create the sfx

2. I went with WinRar as follows, this does not require you to create an sfx file, everything can be created via the gui:

   • Select files, right click and select Add to Archive
   • Use Browse.. to create the archive in the folder above
   • Change Archive Format to Zip
   • Enable Create SFX archive
   • Select Advanced tab
   • Select SFX Options
   • Select Setup tab
   • Enter setup.exe into the Run after Extraction field
   • Select Modes tab
   • Enable Unpack to temporary folder
   • Select text and Icon tab
   • Enter a more appropriate title for your task
   • Select OK
   • Select OK

The resultant exe unzips to a temporary folder and then starts the installer

for those like me still stuck with SQL Server 2000, SET ROWCOUNT {number}; can be used before the UPDATE query

SET ROWCOUNT 100;
UPDATE Table SET ..;
SET ROWCOUNT 0;

will limit the update to 100 rows

It has been deprecated at least since SQL 2005, but as of SQL 2017 it still works. https://docs.microsoft.com/en-us/sql/t-sql/statements/set-rowcount-transact-sql?view=sql-server-2017

Subset is a very slow function , and I personally find it useless.

I assume you have a data.frame, array, matrix called Mat with A, B, C as column names; then all you need to do is:

• In the case of one condition on one column, lets say column A

  Mat[which(Mat[,'A'] == 10), ]
  

In the case of multiple conditions on different column, you can create a dummy variable. Suppose the conditions are A = 10, B = 5, and C > 2, then we have:

    aux = which(Mat[,'A'] == 10)
    aux = aux[which(Mat[aux,'B'] == 5)]
    aux = aux[which(Mat[aux,'C'] > 2)]
    Mat[aux, ]

By testing the speed advantage with system.time, the which method is 10x faster than the subset method.

Your web.config file should have this structure:

<configuration>
    <connectionStrings>
        <add name="MyConnectionString" connectionString="..." />
    </connectionStrings>
</configuration>

Then, to create a SQL connection using the connection string named MyConnectionString:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);

If you'd prefer to keep your connection strings in the AppSettings section of your configuration file, it would look like this:

<configuration>
    <appSettings>
        <add key="MyConnectionString" value="..." />
    </appSettings>
</configuration>

And then your SqlConnection constructor would look like this:

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyConnectionString"]);

I know in the question you state "I assume JavaScript is used to create this effect" but CSS can be used too, an example is below.

CSS

.fancy-link {
   color: #333333;
   text-decoration: none;
   transition: color 0.3s linear;
   -webkit-transition: color 0.3s linear;
   -moz-transition: color 0.3s linear;
}

.fancy-link:hover {
   color: #F44336;
}

HTML

<a class="fancy-link" href="#">My Link</a>

And here is a JSFIDDLE for the above code!

Marcel in one of the answers points out you can "transition multiple CSS properties" you can also use "all" to effect the element with all your :hover styles like below.

CSS

.fancy-link {
   color: #333333;
   text-decoration: none;
   transition: all 0.3s linear;
   -webkit-transition: all 0.3s linear;
   -moz-transition: all 0.3s linear;
}

.fancy-link:hover {
   color: #F44336;
   padding-left: 10px;
}

HTML

<a class="fancy-link" href="#">My Link</a>

And here is a JSFIDDLE for the "all" example!

I also had this problem. I used information from link, mentioned above, and found quick solution. If you have different schema, lets say test, and create user utest, owner of schema test and among views in schema test you have view vTestView, based on tables from schema dbo, while selecting from it you'll get error mentioned above - no access to base objects. It was enough for me to execute statement

ALTER AUTHORIZATION ON test.vTestView TO dbo;

which means that I change an ownership of vTextView from schema it belongs to (test) to database user dbo, owner of schema dbo. After that without any other permissions required user utest will be able to access data from test.vTestView

I would argue you might want to use a cursor when you want to do comparisons of characteristics that are on different rows of the return set, or if you want to write a different output row format than a standard one in certain cases. Two examples come to mind:

1. One was in a college where each add and drop of a class had its own row in the table. It might have been bad design but you needed to compare across rows to know how many add and drop rows you had in order to determine whether the person was in the class or not. I can't think of a straight forward way to do that with only sql.

2. Another example is writing a journal total line for GL journals. You get an arbitrary number of debits and credits in your journal, you have many journals in your rowset return, and you want to write a journal total line every time you finish a journal to post it into a General Ledger. With a cursor you could tell when you left one journal and started another and have accumulators for your debits and credits and write a journal total line (or table insert) that was different than the debit/credit line.

I had same issue and I solved it by "pod setup" after installing cocoapods.

<form action="portfolio.html">
 <button type="link" class="btn btn-primary btn-lg">View Work</button>
</form>

I just figured this out, and it links perfectly to another page without having my default link settings over ride my button classes! :)

Simply, You can make this method static as below:

public static void startChronometer(){
    mChronometer.start();
    showElapsedTime();
} 

you can call this function in other class as below:

MainActivity.startChronometer();

I also faced the same problem.I resolved by doing the build by following steps as.

-->Right click on the project select RunAs ->Run configurations

Select your project as BaseDirectory. In place of goals give eclipse:eclipse install

-->In the second tab give -Xmx1024m as VM arguments.

Short but sweet: for i in {1..10}; do history -d $(($HISTCMD-11)); done

Whammo blammo (for leading spaces):

SELECT 
    RIGHT(space(60) + cust_name, 60),
    RIGHT(space(60) + cust_address, 60)

OR (for trailing spaces)

SELECT
    LEFT(cust_name + space(60), 60),
    LEFT(cust_address + space(60), 60),

Its a common error which happens when we try to access a database which doesn't exist. So create the database using

CREATE DATABASE blog_development;

The error commonly occours when we have dropped the database using

DROP DATABASE blog_development;

and then try to access the database.

Query string parameters can be accepted simply by using an argument on the action - i.e.

public ActionResult Foo(string someValue, int someOtherValue) {...}

which will accept a query like .../someroute?someValue=abc&someOtherValue=123

Other than that, you can look at the request directly for more control.

I just discovered PixieDebugger. Even thought I have not yet had the time to test it, it really seems the most similar way to debug the way we're used in ipython with ipdb

It also has an "evaluate" tab

Updating the ~/.profile or ~/.bash_profile does not work sometimes. I just deleted JDK 6 and sourced .bash_profile.

Try running this:

sudo rm -rd jdk1.6.0_* #it may not let you delete without sudo

Then, modify/add your JAVA_HOME and PATH variables.

source ~/.bash_profile #assuming you've updated $JAVA_HOME and $PATH

Is the indexOf(String) method case sensitive?

Yes, it is case sensitive:

@Test
public void indexOfIsCaseSensitive() {
    assertTrue("Hello World!".indexOf("Hello") != -1);
    assertTrue("Hello World!".indexOf("hello") == -1);
}

If so, is there a case insensitive version of it?

No, there isn't. You can convert both strings to lower case before calling indexOf:

@Test
public void caseInsensitiveIndexOf() {
    assertTrue("Hello World!".toLowerCase().indexOf("Hello".toLowerCase()) != -1);
    assertTrue("Hello World!".toLowerCase().indexOf("hello".toLowerCase()) != -1);
}

API:

[HttpPost]
public bool UpdateTicketStatus(Ticket t)
{    
    string Id=t.Id;
}

Model:

public class Ticket
{
    public int Id { get; set; }
    public string AssignedTo { get; set; }
    public string State { get; set; }
    public string History { get; set; }
}

Using Post man tool send the content as json with raw data as below. It works

{ "Id":"169248", "AssignedTo":"xxxx", "State":"Committed", "History":"test1" }

Please make sure that you have enabled Cors.

[EnableCors(origins: "*", headers: "*", methods: "*")]
    public class TicketController : ApiController
    {
}

This is what I'm teaching my students tomorrow. After years of looking at this stuff... ie all of the documentation above http://www.cpearson.com/excel/errorhandling.htm comes to mind as an excellent one...

I hope this summarizes it for others. There is an Err object and an active (or inactive) ErrorHandler. Both need to be handled and reset for new errors.

Paste this into a workbook and step through it with F8.

Sub ErrorHandlingDemonstration()

    On Error GoTo ErrorHandler

    'this will error
    Debug.Print (1 / 0)

    'this will also error
    dummy = Application.WorksheetFunction.VLookup("not gonna find me", Range("A1:B2"), 2, True)

    'silly error
    Dummy2 = "string" * 50

    Exit Sub

zeroDivisionErrorBlock:
    maybeWe = "did some cleanup on variables that shouldnt have been divided!"
    ' moves the code execution to the line AFTER the one that errored
    Resume Next

vlookupFailedErrorBlock:
    maybeThisTime = "we made sure the value we were looking for was in the range!"
    ' moves the code execution to the line AFTER the one that errored
    Resume Next

catchAllUnhandledErrors:
    MsgBox(thisErrorsDescription)
    Exit Sub

ErrorHandler:
    thisErrorsNumberBeforeReset = Err.Number
    thisErrorsDescription = Err.Description
    'this will reset the error object and error handling
    On Error GoTo 0
    'this will tell vba where to go for new errors, ie the new ErrorHandler that was previous just reset!
    On Error GoTo ErrorHandler

    ' 11 is the err.number for division by 0
    If thisErrorsNumberBeforeReset = 11 Then
        GoTo zeroDivisionErrorBlock
    ' 1004 is the err.number for vlookup failing
    ElseIf thisErrorsNumberBeforeReset = 1004 Then
        GoTo vlookupFailedErrorBlock
    Else
        GoTo catchAllUnhandledErrors
    End If

End Sub

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

You can now use fetch API/ It returns redirected: *boolean*

Actually, you need to call SET SERVEROUTPUT ON; before the BEGIN call.

Everyone suggested this but offers no advice where to actually place the line:

SET SERVEROUTPUT ON;

BEGIN
    FOR rec in (SELECT * FROM EMPLOYEES) LOOP
        DBMS_OUTPUT.PUT_LINE(rec.EmployeeName);
    ENDLOOP;
END;

Otherwise, you won't see any output.

view = MyCustomView(frame: CGRectZero)

In this line you are trying to set empty rect for your custom view. That's why you cant see your view in simulator.

How about

wc -l file.txt | cut -d' ' -f1

i.e. pipe the output of wc into cut (where delimiters are spaces and pick just the first field)

Try this:

Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

Range("A2:L" & Lastrow).Select

Let's pretend that the value of Lastrow is 50. When you use the following:

Range("A2:L2" & Lastrow).Select

Then it is selecting a range from A2 to L250.

TOAD for MS SQL looks pretty good. I've never used it personally but I have used Quest's other products and they're solid.

Look at this:

function isPalindrome(word){
    if(word==null || word.length==0){
        // up to you if you want true or false here, don't comment saying you 
        // would put true, I put this check here because of 
        // the following i < Math.ceil(word.length/2) && i< word.length
        return false;
    }
    var lastIndex=Math.ceil(word.length/2);
    for (var i = 0; i < lastIndex  && i< word.length; i++) {
        if (word[i] != word[word.length-1-i]) {
            return false;
        }
     }
     return true;
} 

Edit: now half operation of comparison are performed since I iterate only up to half word to compare it with the last part of the word. Faster for large data!!!

Since the string is an array of char no need to use charAt functions!!!
