for me, it solved just by changing the name of my cell's file into the same as its class.
In Attributes Inspector(Third tab on the right side bar in story board):
Register the cell in your view controller as follow:
tableView.register(UINib(nibName: "MyCellClass", bundle: nil), forCellReuseIdentifier: "MyCellId")
This can also happen when you forget to make a first commit.
Also good to check is telephony supported on device
private boolean isTelephonyEnabled(){
TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
return tm != null && tm.getSimState()==TelephonyManager.SIM_STATE_READY
}
setInterval()
setInterval is a time interval based code execution method that has the native ability to repeatedly run specified script when the interval is reached. It should not be nested into its callback function by the script author to make it loop, since it loops by default. It will keep firing at the interval unless you call clearInterval().
if you want to loop code for animations or clocks Then use setInterval.
function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setInterval(doStuff, 5000);
setTimeout()
setTimeout is a time based code execution method that will execute script only one time when the interval is reached, and not repeat again unless you gear it to loop the script by nesting the setTimeout object inside of the function it calls to run. If geared to loop, it will keep firing at the interval unless you call clearTimeout().
function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setTimeout(doStuff, 5000);
if you want something to happen one time after some seconds Then use setTimeout... because it only executes one time when the interval is reached.
I usually add to index changes I don't want to stash and then stash with --keep-index
option.
git add app/controllers/cart_controller.php
git stash --keep-index
git reset
Last step is optional, but usually you want it. It removes changes from index.
Warning
As noted in the comments, this puts everything into the stash, both staged and unstaged. The --keep-index
just leaves the index alone after the stash is done. This can cause merge conflicts when you later pop the stash.
If the content is a variable, it will be necessary to concatenate it with quotation marks. It worked for me. Like this:
itemSelected(id: number){ console.log('label contains', document.querySelector("label[for='" + id + "']")); }
Each time the same will be generated:
if let uuid = UIDevice.current.identifierForVendor?.uuidString {
print(uuid)
}
Each time a new one will be generated:
let uuid = UUID().uuidString
print(uuid)
I was able to setup Oracle Instant Client (Basic) 11g2 and Oracle ODBC (32bit) drivers on my 32bit Windows 7 PC. Note: you'll need a 'tnsnames.ora' file because it doesn't come with one. You can Google examples and copy/paste into a text file, change the parameters for your environment.
Setting up Oracle Instant Client-Basic 11g2 (Win7 32-bit)
(I think there's another step or two if your using 64-bit)
Oracle Instant Client
ODBC Drivers
Note: The "un-documented" things that were hanging me up where...
- All files (Client and Drivers) needed to be in the same folder (nothing in sub-folders).
- Running the ODBC driver from the command prompt will allow you to see if it installs successfully. Double-clicking the installer just flashed a box on the screen, no idea it was failing because no error dialog.
After you've done this you should be able to setup a new DSN Data Source using the Oracle ODBC driver.
-Hope this helps someone else.

Following Glens idea, here it goes another possibility. It would allow you to scroll inside the div, but would prevent the body to scroll with it, when the div scroll ends. However, it seems to accumulate too many preventDefault if you scroll too much, and then it creates a lag if you want to scroll up. Does anybody have a suggestion to fix that?
$(".scrollInsideThisDiv").bind("mouseover",function(){
var bodyTop = document.body.scrollTop;
$('body').on({
'mousewheel': function(e) {
if (document.body.scrollTop == bodyTop) return;
e.preventDefault();
e.stopPropagation();
}
});
});
$(".scrollInsideThisDiv").bind("mouseleave",function(){
$('body').unbind("mousewheel");
});
If you need to delect IE Browser version then you can follow below code. This code working well for version IE6 to IE11

//For IE 11 >
if (navigator.appName == 'Netscape') {
var ua = navigator.userAgent;
var re = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
if (re.exec(ua) != null) {

You have to specify project_id

A small variation but nothing new infact. It's really missing a feature...
select info->>'name' from rabbits
where '"carrots"' = ANY (ARRAY(
select * from json_array_elements(info->'food'))::text[]);
Since I cannot comment, adding this note in addition to @jethro answer.
I found out that you also need to do the FOREIGN KEY line as the last part of create the table statement, otherwise you will get a syntax error when installing your app. What I mean is, you cannot do something like this:
private static final String TASK_TABLE_CREATE = "create table "
+ TASK_TABLE + " (" + TASK_ID
+ " integer primary key autoincrement, " + TASK_TITLE
+ " text not null, " + TASK_NOTES + " text not null, "
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+" ("+CAT_ID+"), "
+ TASK_DATE_TIME + " text not null);";
Where I put the TASK_DATE_TIME after the foreign key line.
You can also copy a cell which contains the conditional formatting and then select the range (of destination document -or page-) where you want the conditional format to be applied and select "paste special" > "paste only conditional formatting"
You can also increase it via the VM arguments in your IDE. In my case, I am using Tomcat v7.0 which is running on Eclipse. To do this, double click on your server (Tomcat v7.0). Click the 'Open launch configuration' link. Go to the 'Arguments' tab. Add -XX:MaxPermSize=512m to the VM arguments list. Click 'Apply' and then 'OK'. Restart your server.
The seek
function expect's an offset in bytes.
So if you have a text file with the following content:
simple.txt
abc
You can jump 1 byte to skip over the first character as following:
fp = open('simple.txt', 'r')
fp.seek(1)
print fp.readline()
>>> bc
fp = open('afile.png', 'rb')
fp.seek(16)
print 'width: {0}'.format(struct.unpack('>i', fp.read(4))[0])
print 'height: ', struct.unpack('>i', fp.read(4))[0]
Note: Once you call
read
you are changing the position of the read-head, which act's likeseek
.
With POD you can also write
Snapshot s = {};
You shouldn't use memset in C++, memset has the drawback that if there is a non-POD in the struct it will destroy it.
or like this:
struct init
{
template <typename T>
operator T * ()
{
return new T();
}
};
Snapshot* s = init();

I'm a bit late to the answer, but you may want to do this if you want the whole element, not only the values you want to group by:
var query = doc.Elements("whatever")
.GroupBy(element => new {
id = (int) element.Attribute("id"),
category = (int) element.Attribute("cat") })
.Select(e => e.First());
This will give you the first whole element matching your group by selection, much like Jon Skeets second example using DistinctBy, but without implementing IEqualityComparer comparer. DistinctBy will most likely be faster, but the solution above will involve less code if performance is not an issue.
Setup ANDROID_HOME , JAVA_HOME enviromental variable on Mac OS X
Add In .bash_profile file
export JAVA_HOME=$(/usr/libexec/java_home)
export ANDROID_HOME=/Users/$USER/Library/Android/sdk
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
For Test
echo $ANDROID_HOME
echo $JAVA_HOME
Create a .vbs
file with this code:
CreateObject("Wscript.Shell").Run "your_batch.bat",0,True
This .vbs
will run your_batch.bat
hidden.
Works fine for me.
This should give you the commands printed out in separate lines:
import readline
map(lambda p:print(readline.get_history_item(p)),
map(lambda p:p, range(readline.get_current_history_length()))
)
I guess that '$PATH_TO_SOMEWHERE'
is something like '<directory>/*'
.
In this case, I would change the code to:
find <directory> -maxdepth 1 -type d -exec ... \;
find <directory> -maxdepth 1 -type f -name "*.txt" -exec ... \;
If you want to do something more complicated with the directory and text file names, you could:
find <directory> -maxdepth 1 -type d | while read dir; do echo $dir; ...; done
find <directory> -maxdepth 1 -type f -name "*.txt" | while read txtfile; do echo $txtfile; ...; done
If you have spaces in your file names, you could:
find <directory> -maxdepth 1 -type d | xargs ...
find <directory> -maxdepth 1 -type f -name "*.txt" | xargs ...
A good solution here for VSCode users, if a string breaking down into multiple lines causes the problem (I faced this when I had to test a long JWT token, and somehow using template literals didn't do the trick.)
So the question is how can I check if my array already has a "horse" included so that I don't fill it with the same horse?
While the answers are concerned with looking through the array to see if a particular string or object exists, that's really going about it wrong, because, as the array gets larger, the search will take longer.
Instead, use either a Hash, or a Set. Both only allow a single instance of a particular element. Set will behave closer to an Array but only allows a single instance. This is a more preemptive approach which avoids duplication because of the nature of the container.
hash = {}
hash['a'] = nil
hash['b'] = nil
hash # => {"a"=>nil, "b"=>nil}
hash['a'] = nil
hash # => {"a"=>nil, "b"=>nil}
require 'set'
ary = [].to_set
ary << 'a'
ary << 'b'
ary # => #<Set: {"a", "b"}>
ary << 'a'
ary # => #<Set: {"a", "b"}>
Hash uses name/value pairs, which means the values won't be of any real use, but there seems to be a little bit of extra speed using a Hash, based on some tests.
require 'benchmark'
require 'set'
ALPHABET = ('a' .. 'z').to_a
N = 100_000
Benchmark.bm(5) do |x|
x.report('Hash') {
N.times {
h = {}
ALPHABET.each { |i|
h[i] = nil
}
}
}
x.report('Array') {
N.times {
a = Set.new
ALPHABET.each { |i|
a << i
}
}
}
end
Which outputs:
user system total real
Hash 8.140000 0.130000 8.270000 ( 8.279462)
Array 10.680000 0.120000 10.800000 ( 10.813385)
I prefer this solution;
head -$(gcalctool -s $(cat file | wc -l)-N) file
where N is the number of lines to remove.
lsof +f -- /mountpoint
(as lists the processes using files on the mount mounted at /mountpoint. Particularly useful for finding which process(es) are using a mounted USB stick or CD/DVD.
I am using a Mac. I had the same problem wherein .csv file was in the same folder where the python script was placed, however, Spyder still was unable to locate the file. I changed the file name from capital letters to all small letters and it worked.
Single liner works
df['Name'] = 'abc'
Creates a Name
column and sets all rows to abc
value
The other answers didn't work for me, this is what ended up doing the trick for apache2:
1) Enable the headers mod:
sudo a2enmod headers
2) Create the /etc/apache2/mods-enabled/headers.conf
file and insert:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
3) Restart your server:
sudo service apache2 restart

Some of you guys have great answers, but I found some additional thing. If you want create a MenuItem with some SubMenu programmatically:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
SubMenu subMenu = menu.addSubMenu(0, Menu.NONE, 0, "Menu title");
subMenu.getItem().setIcon(R.drawable.ic_action_child);
subMenu.getItem().setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
subMenu.add(0, Menu.NONE, 0, "Subitem 1");
subMenu.add(0, Menu.NONE, 1, "Subitem 2");
subMenu.add(0, Menu.NONE, 2, "Subitem 3");
return true;
}
string.join the list values separated by commas, and use the format operator to form a query string.
myquery = "select name from studens where id in (%s)" % ",".join(map(str,mylist))
(Thanks, blair-conrad)
This is explained quite well in the Python documentation:
repr(object): Return a string containing a printable representation of an object. This is the same value yielded by conversions (reverse quotes). It is sometimes useful to be able to access this operation as an ordinary function. For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to
eval()
, otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a__repr__()
method.
So what you're seeing here is the default implementation of __repr__
, which is useful for serialization and debugging.
If your minSdkVersion
is 21+ use android:buttonTint
attribute to update the color of a checkbox:
<CheckBox
...
android:buttonTint="@color/tint_color" />
In projects that use AppCompat library and support Android versions below 21 you can use a compat version of the buttonTint
attribute:
<CheckBox
...
app:buttonTint="@color/tint_color" />
In this case if you want to subclass a CheckBox
don't forget to use AppCompatCheckBox
instead.
PREVIOUS ANSWER:
You can change CheckBox
s drawable using android:button="@drawable/your_check_drawable"
attribute.
Java 8 lambda expressions. Both fast and simple.
boolean allLetters = someString.chars().allMatch(Character::isLetter);
Go to command prompt and enter the command,
net user <username>
Will show your local group memberships.
If you're on a domain, use localgroup instead:
net localgroup Administrators or net localgroup [Admin group name]
Check the list of local groups with localgroup on its own.
net localgroup
It is not enough in case of PHP fpm. It was one more configuration file which can enable display_error
. You should find www.conf. In my case it is in directory /etc/php/7.1/fpm/pool.d/
You should find php_flag[display_errors] = on
and disable it, php_flag[display_errors] = off
. This should solve the issue.
In order to exit from the app on pressing back button you have to first clear all the top activities and then start the ACTION_MAIN of android phone
So, you have to write all these code only which is mentioned below :
Note : In your case MainActivity get replaced by YourActivity
@Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setTitle("Really Exit?")
.setMessage("Are you sure you want to exit?")
.setNegativeButton(android.R.string.no, null)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
MainActivity.super.onBackPressed();
quit();
}
}).create().show();
}
public void quit() {
Intent start = new Intent(Intent.ACTION_MAIN);
start.addCategory(Intent.CATEGORY_HOME);
start.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
start.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(start);
}
Here's what I use at the top of all my batch files. I just copy/paste from my template folder.
@echo off
:: --HAS ENDING BACKSLASH
set batdir=%~dp0
:: --MISSING ENDING BACKSLASH
:: set batdir=%CD%
pushd "%batdir%"
Setting current batch file's path to %batdir% allows you to call it in subsequent stmts in current batch file, regardless of where this batch file changes to. Using PUSHD allows you to use POPD to quickly set this batch file's path to original %batdir%. Remember, if using %batdir%ExtraDir or %batdir%\ExtraDir (depending on which version used above, ending backslash or not) you will need to enclose the entire string in double quotes if path has spaces (i.e. "%batdir%ExtraDir"). You can always use PUSHD %~dp0. [https: // ss64.com/ nt/ syntax-args .html] has more on (%~) parameters.
Note that using (::) at beginning of a line makes it a comment line. More importantly, using :: allows you to include redirectors, pipes, special chars (i.e. < > | etc) in that comment.
:: ORIG STMT WAS: dir *.* | find /v "1917" > outfile.txt
Of course, Powershell does this and lots more.
Your selector is a little off, it's missing the trailing ]
var mySelect = $('select[name=' + name + ']')
you may also need to put quotes around the name, like so:
var mySelect = $('select[name="' + name + '"]')
My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):
Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".
Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"
Not sure why both were needed. I used this to remove a dependency on glut32.dll.
Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.
Not authoritative, but interesting: 21 is FTP, 23 is telnet. 22 is SSH...something in between (that can take the place of both).
I recently published a project that allows PHP to obtain and interact with a real Bash shell. Get it here: https://github.com/merlinthemagic/MTS The shell has a pty (pseudo terminal device, same as you would have in i.e. a ssh session), and you can get the shell as root if desired. Not sure you need root to execute your script, but given you mention sudo it is likely.
After downloading you would simply use the following code:
$shell = \MTS\Factories::getDevices()->getLocalHost()->getShell('bash', true);
$return1 = $shell->exeCmd('/path/to/osascript myscript.scpt');
Try the Parse method.
Hope it will work for you.

After going back and looking at many of the other answers I found that a deeper explanation is in order, as many of the other answers either suffer from performance problems or force you to use unusual or burdensome syntax to declare the array, or access the array elements ( or all the above ).
First off, this answer assumes you know the dimensions of the array at compile time. If you do, then this is the best solution as it will both give the best performance and allows you to use standard array syntax to access the array elements.
The reason this gives the best performance is because it allocates all of the arrays as a contiguous block of memory meaning that you are likely to have less page misses and better spacial locality. Allocating in a loop may cause the individual arrays to end up scattered on multiple non-contiguous pages through the virtual memory space as the allocation loop could be interrupted ( possibly multiple times ) by other threads or processes, or simply due to the discretion of the allocator filling in small, empty memory blocks it happens to have available.
The other benefits are a simple declaration syntax and standard array access syntax.
In C++ using new:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv) {
typedef double (array5k_t)[5000];
array5k_t *array5k = new array5k_t[5000];
array5k[4999][4999] = 10;
printf("array5k[4999][4999] == %f\n", array5k[4999][4999]);
return 0;
}
Or C style using calloc:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv) {
typedef double (*array5k_t)[5000];
array5k_t array5k = calloc(5000, sizeof(double)*5000);
array5k[4999][4999] = 10;
printf("array5k[4999][4999] == %f\n", array5k[4999][4999]);
return 0;
}
webDriver.findElement(By.xpath("//a[@href='/docs/configuration']")).click();
The above line works fine. Please remove the space after href.
Is that element is visible in the page, if the element is not visible please scroll down the page then perform click action.
It is just called the eyedropper tool. There is no shortcut key for it that I'm aware of. The only way you can use it now is by clicking on the color picker box in styles sidebar and then clicking on the page as you have already been doing.
The first thing that comes to my mind is a one-liner regex:
var pageNum = $("#specificLink").attr("href").match(/page=([0-9]+)/)[1];
Here is a very simple way to do this (using SQL 2012 or later)
datefromparts(year(getdate()),month(getdate()),1)
you can also easily get the last day of the month using
eomonth(getdate())
Try this..
select starttime,endtime, case
when DATEDIFF(minute,starttime,endtime) < 60 then DATEDIFF(minute,starttime,endtime)
when DATEDIFF(minute,starttime,endtime) >= 60
then '60,'+ cast( (cast(DATEDIFF(minute,starttime,endtime) as int )-60) as nvarchar(50) )
end from TestTable123416
All You need is DateDiff..
You need run visudo
and in the editor that it opens write:
igor ALL=(ALL) ALL
That line grants all permissions to user igor
.
If you want permit to run only some commands, you need to list them in the line:
igor ALL=(ALL) /bin/kill, /bin/ps
I'm making a guess here, but your start
invocation probably looks like this:
start "\Foo\Bar\Path with spaces in it\program.exe"
This will open a new console window, using “\Foo\Bar\Path with spaces in it\program.exe” as its title.
If you use start
with something that is (or needs to be) surrounded by quotes, you need to put empty quotes as the first argument:
start "" "\Foo\Bar\Path with spaces in it\program.exe"
This is because start
interprets the first quoted argument it finds as the window title for a new console window.
Try like this.It should work
Response.Redirect(String.Format("yourpage.aspx?strId={0}&strName={1}&strDate{2}", Server.UrlEncode(strId), Server.UrlEncode(strName),Server.UrlEncode(strDate)));
Here are two examples of how to generate graphs in separate windows (frames), and, an example of how to generate graphs and save them into separate graphics files.
Okay, first the on-screen example. Notice that we use a separate instance of plt.figure(), for each graph, with plt.plot(). At the end, we have to call plt.show() to put it all on the screen.
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace( 0,10 )
for n in range(3):
y = np.sin( x+n )
plt.figure()
plt.plot( x, y )
plt.show()
Another way to do this, is to use plt.show(block=False) inside the loop:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace( 0,10 )
for n in range(3):
y = np.sin( x+n )
plt.figure()
plt.plot( x, y )
plt.show( block=False )
Now, let's generate the graphs and instead, write them each to a file. Here we replace plt.show(), with plt.savefig( filename ). The difference from the previous example is that we don't have to account for ''blocking'' at each graph. Note also, that we number the file names. Here we use %03d so that we can conveniently have them in number order afterwards.
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace( 0,10 )
for n in range(3):
y = np.sin( x+n )
plt.figure()
plt.plot( x, y )
plt.savefig('myfilename%03d.png'%(n))
Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
For this case, especially on Android, the way going for bytes is usually faster.
With this, I solved it by setting up a class FileHelper
which is given the responsibility to deal with reading/writing bytes from/to file through stream and a class UriHelper
which is given the responsibility to figure out path of Uri and permission.
As far as it's knew generally, string.getBytes((charset == null) ? DEFAULT_CHARSET:charset)
can help us to transfer string you want to bytes you need.
How to let UriHelper and FileHelper you to copy a picture noted by Uri into a file, you can run:
FileHelper.getInstance().copy(UriHelper.getInstance().toFile(uri_of_a_picture)
, FileHelper.getInstance().createExternalFile(null, UriHelper.getInstance().generateFileNameBasedOnTimeStamp()
+ UriHelper.getInstance().getFileName(uri_of_a_picture, context), context)
);

Since I had to do something like this, here's my solution given a generator and a batch size:
def pop_n_elems_from_generator(g, n):
elems = []
try:
for idx in xrange(0, n):
elems.append(g.next())
return elems
except StopIteration:

I upgraded from Silverlight 4 to Silverlight 5 and then I was having this issue. Although I had a reference to "System.ComponentModel.DataAnnotations" under "References" in my project, it had a yellow yield sign by it that indicated the previously referenced assembly could not be found. It turned out that the properties of the "System.ComponentModel.DataAnnotations" reference indicated "Specific Version = True", when I changed this to "Specific Version = False" it fixed the issue. Right click on the "System.ComponentModel.DataAnnotations" assembly under "References" and select "Properties" from the context menu. Check that the property value for "Specific Version = False".
It must have been referencing the old Silverlight 4 assembly which was no longer available after the upgrade to Silverlight 5.
If you want to get the value, you can use this code for a select element with the id="selectBox"
let myValue = document.querySelector("#selectBox").value;
If you want to get the text, you can use this code
var sel = document.getElementById("selectBox");
var text= sel.options[sel.selectedIndex].text;
For me there was no default constructor defined for the POJOs I was trying to use. creating default constructor fixed it.
public class TeamCode {
@Expose
private String value;
public String getValue() {
return value;
}
**public TeamCode() {
}**
public TeamCode(String value) {
this.value = value;
}
@Override
public String toString() {
return "TeamCode{" +
"value='" + value + '\'' +
'}';
}
public void setValue(String value) {
this.value = value;
}
}

Map is the static type of map, while HashMap is the dynamic type of map. This means that the compiler will treat your map object as being one of type Map, even though at runtime, it may point to any subtype of it.
This practice of programming against interfaces instead of implementations has the added benefit of remaining flexible: You can for instance replace the dynamic type of map at runtime, as long as it is a subtype of Map (e.g. LinkedHashMap), and change the map's behavior on the fly.
A good rule of thumb is to remain as abstract as possible on the API level: If for instance a method you are programming must work on maps, then it's sufficient to declare a parameter as Map instead of the stricter (because less abstract) HashMap type. That way, the consumer of your API can be flexible about what kind of Map implementation they want to pass to your method.
I ran into this as well and tried all of the other solutions. I did not have the .class file in my HTML folder, I only had the .java file. Once I added the .class file the program worked fine.
I've been trying to get this working. Here's what works:
Example:
mod.mjs
export const STR = 'Hello World'
test.mjs
import {STR} from './mod.mjs'
console.log(STR)
Run: node test.mjs
You should see "Hello World".
if your intention is send the full array from the html to the controller, can use this:
from the blade.php:
<input type="hidden" name="quotation" value="{{ json_encode($quotation,TRUE)}}">
in controller
public function Get(Request $req) {
$quotation = array('quotation' => json_decode($req->quotation));
//or
return view('quotation')->with('quotation',json_decode($req->quotation))
}
For databases:
Just use these commands:
USE db_name;
SELECT @@character_set_database;
-- or:
-- SELECT @@collation_database;
You can use return false;
+----------------------------------------+
| JavaScript | PHP |
+-------------------------+--------------+
| | |
| return false; | break; |
| | |
| return true; or return; | continue; |

For detecting if the form is present, I'm using
if($('form[name="frmSave"]').length > 0) {
//do something
}
This excludes the final word instead of including it.
function smartTrim(str, length, delim, appendix) {
if (str.length <= length) return str;
var trimmedStr = str.substr(0, length+delim.length);
var lastDelimIndex = trimmedStr.lastIndexOf(delim);
if (lastDelimIndex >= 0) trimmedStr = trimmedStr.substr(0, lastDelimIndex);
if (trimmedStr) trimmedStr += appendix;
return trimmedStr;
}
Usage:
smartTrim(yourString, 11, ' ', ' ...')
"The quick ..."
try this one, it is working fine for me.
"^([a-zA-Z])[a-zA-Z0-9-_]*$"
use the .size()
method or .length
attribute
This should work...
var displayDate = new Date().toLocaleDateString();
alert(displayDate);
But I suspect you are trying it on something else, for example:
var displayDate = Date.now.toLocaleDateString(); // No!
alert(displayDate);
you can use more elements "end" in print:
for iValue in arr:
print(iValue, end = ", ");
You could use width: 100%;
in your css.
Recently I had a similar problem, the problem was I was using background-color, use background: {anyColor}
example:
tr::hover td {background: red;}
This works like charm!
You need to precede the lines starting with gcc
and rm
with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line).
The result should look like this:
PROG = semsearch
all: $(PROG)
%: %.c
gcc -o $@ $< -lpthread
clean:
rm $(PROG)
Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:
PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread
clean: ; rm $(PROG)
If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:
Just Store the current time and If it exceeds 30 minutes by comparing then destroy the current session.
Reflection and dynamic value access are correct solutions to this question but are quite slow. If your want something faster then you can create dynamic method using expressions:
object value = GetValue();
string propertyName = "MyProperty";
var parameter = Expression.Parameter(typeof(object));
var cast = Expression.Convert(parameter, value.GetType());
var propertyGetter = Expression.Property(cast, propertyName);
var castResult = Expression.Convert(propertyGetter, typeof(object));//for boxing
var propertyRetriver = Expression.Lambda<Func<object, object>>(castResult, parameter).Compile();
var retrivedPropertyValue = propertyRetriver(value);
This way is faster if you cache created functions. For instance in dictionary where key would be the actual type of object assuming that property name is not changing or some combination of type and property name.
A working example:
$qb = $this->createQueryBuilder('a');
$query=$qb->getQuery();
// SHOW SQL:
echo $query->getSQL();
// Show Parameters:
echo $query->getParameters();
This will capture everything up to the ' in backreference 1 - and everything after the ' in backreference 2. You may need to escape the apostrophes though depending on language (\')
/^([^']*)'?(.*)$/
Quick modification: if the line doesn't have an ' - backreference 1 should still catch the whole line.
^ - start of string
([^']*) - capture any number of not ' characters
'? - match the ' 0 or 1 time
(.*) - capture any number of characters
$ - end of string
Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>
. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx">
The resulting contents are :
Component1.html
<nav>
<a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
<router-outlet></router-outlet>
Component2.html
<a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ... </a>
<a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]"> In Two...Go to 4 ...</a>
<router-outlet name="nameThree"></router-outlet>
<router-outlet name="nameFour"></router-outlet>
The '/two'
represents the parent component and ['three']
and ['four']
represents the link to the respective children of component2
. Component3.html and Component4.html are the same as in the question.
router.module.ts
const routes: Routes = [
{
path: '',
redirectTo: 'one',
pathMatch: 'full'
},
{
path: 'two',
component: ClassTwo, children: [
{
path: 'three',
component: ClassThree,
outlet: 'nameThree'
},
{
path: 'four',
component: ClassFour,
outlet: 'nameFour'
}
]
},];
Don't know what you are doing (helpful to show what you tried that didn't work), but your claim that cex.axis
only affects the x-axis is not true:
set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data = foo, cex.axis = 3)

Also, cex.axis
affects the labelling of tick marks. cex.lab
is used to control what R call the axis labels.
plot(Y ~ X, data = foo, cex.lab = 3)
but even that works for both the x- and y-axis.
Following up Jens' comment about using barplot()
. Check out the cex.names
argument to barplot()
, which allows you to control the bar labels:
dat <- rpois(10, 3) names(dat) <- LETTERS[1:10] barplot(dat, cex.names = 3, cex.axis = 2)
As you mention that cex.axis
was only affecting the x-axis I presume you had horiz = TRUE
in your barplot()
call as well? As the bar labels are not drawn with an axis()
call, applying Joris' (otherwise very useful) answer with individual axis()
calls won't help in this situation with you using barplot()

Note: In each of these examples, you can prepend multiple items by providing more items to insert.
You can get the maximum like this:
>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]]
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]].max(axis=1)
0 1
1 8
2 3
and so:
>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
If you know that "A" and "B" are the only columns, you could even get away with
>>> df["C"] = df.max(axis=1)
And you could use .apply(max, axis=1)
too, I guess.
In urlip3 there's no .urlopen

The JDK
uses the same code so it seems like there is no "easier" way without clunky third party libraries (which probably don't do anything different anyway). The following is directly copied from java.nio.file.Files.java
:
// buffer size used for reading and writing
private static final int BUFFER_SIZE = 8192;
/**
* Reads all bytes from an input stream and writes them to an output stream.
*/
private static long copy(InputStream source, OutputStream sink) throws IOException {
long nread = 0L;
byte[] buf = new byte[BUFFER_SIZE];
int n;
while ((n = source.read(buf)) > 0) {
sink.write(buf, 0, n);
nread += n;
}
return nread;
}
Somehow, this fix the issue out of no reason.
./gradlew clean assemble

There are many ways to uninstall an MSI package. This is intended as a "reference".
In summary you can uninstall via: msiexec.exe, ARP, WMI, PowerShell, Deployment Systems such as SCCM, VBScript / COM Automation, DTF, or via hidden Windows cache folder, and a few other options presented below.
The first few paragraphs provide important MSI tidbits, then there are 14 sections with different ways to uninstall an MSI file. Puh.
"Babble, Babble - Over": Sections 1, 2 and 3 are the normal uninstall approaches (and hence recommended).
Personally I use option 3 or 5 from section 3
(both options with logging, but option 5 runs silently as well). If you are very busy, skip all the babble and go for one of these - it will get the job done.
If you have problems uninstalling altogether and are looking for an alternative to the deprecated MsiZap.exe and / or Windows Installer CleanUp Utility (MSICUU2.exe), you can try the new FixIt tool from Microsoft (or the international page). May apparently work for other install issues as well.
Newer list of cleanup approaches: Cleaning out broken MSI uninstalls.
If you think MSI and Windows Installer is more trouble than it's worth, you might want to read about the corporate benefits of using MSI files.
Installscript MSI setups generally come wrapped in a setup.exe file. To read more about the parameters to use for uninstalling such setups please see these links: setup.exe pdf reference sheet, Setup.exe and Update.exe Command-Line Parameters.
Some MSI files are installed as part of bundles via mechanism such as Burn (WiX Toolkit) or InstallShield Suite projects. This can make uninstall slightly different from what is seen below. Here is an example for InstallShield Suite projects.
Be aware that running uninstall silently or interactively can cause different results (!). For a rather lengthy description of why this is the case, please read this post: Uninstall from Control Panel is different from Remove from .msi
If you are unexpectedly asked for the original installation media when trying to uninstall, please read this answer: Why does MSI require the original .msi file to proceed with an uninstall? and perhaps also section 12 below for some important technical details.
If you got CCleaner or similar cleanup tools installed, perhaps jump to section 11.
If uninstall is failing entirely (not possible to run), see sections 12 & 13 below for a potential way to "undo" the installation using system restore and / or cleanup tools.
Using the original MSI
Using the old ARP Applet OR new Windows 8/10 Settings Interface
Just got to mention the normal approach(es) though it is obvious
ARP
= Add / Remove Programs Applet
(appwiz.cpl
)
Windows 10 Settings Interface
=> New shell for same operation
ARP:
Settings Interface (Windows 8 / 10):
Apps & Features
. Select entry and uninstall.ms-settings:appsfeatures
and press EnterUsing msiexec.exe command line (directly or via a batch file)
/qn
to make the uninstall run in silent mode. This is how an uninstall runs when triggered from the add/remove applet.Option 3.1: Basic interactive uninstall (access to original MSI file):
msiexec.exe /x "c:\filename.msi"
Option 3.2: Basic interactive uninstall via product GUID (no access to original MSI file - here is how to find the product GUID - same link as below):
msiexec.exe /x {11111111-1111-1111-1111-11111111111X}
Option 3.3: Interactive uninstall with verbose log file:
msiexec.exe /x "c:\filename.msi" /L*V "C:\msilog.log"
msiexec.exe /x {11111111-1111-1111-1111-11111111111X} /L*V "C:\msilog.log"
Option 3.4: Interactive uninstall with flushed, verbose log file (verbose, flush to log option - write log continuously, can be very slow):
msiexec.exe /x "c:\filename.msi" /L*V! "C:\msilog.log"
msiexec.exe /x {11111111-1111-1111-1111-11111111111X} /L*V! "C:\msilog.log"
The flush to log option makes the uninstall slow because the log file is written continuously instead of in batches. This ensures no log-buffer is lost if the setup crashes.
In other words, enable this option if your setup is crashing and there is no helpful information in your verbose log file. Remove the exclamation mark to turn off the flush to log option and the uninstall will be much quicker. You still get verbose logging, but as stated some log buffer could be lost.
Option 3.5 (recommended): Silent uninstall with verbose log file - suppress reboots (no flush to log - see previous option for what this means):
msiexec.exe /x "c:\filename.msi" /QN /L*V "C:\msilog.log" REBOOT=R
msiexec.exe /x {11111111-1111-1111-1111-11111111111X} /QN /L*V "C:\msilog.log" REBOOT=R
Quick Parameter Explanation (since I recommend this option):
/X = run uninstall sequence
/QN = run completely silently
/L*V "C:\msilog.log"= verbose logging at path specified
{11111111-1111-1111-1111-11111111111X} = product guid of app to uninstall
REBOOT=R = prevent unexpected reboot of computer
Again, how to find the product guid: How can I find the product GUID of an installed MSI setup? (for uninstall if you don't have the original MSI to specify in the uninstall command).
Top tip: If you create a log file for your uninstall, you can locate problems in the log by searching for "value 3". This is particularly useful for verbose files, because they are so, well, verbose :-).
How to find the product GUID for an installed MSI?
More information on logging from installsite.org: How do I create a log file of my installation? - great overview of different options and also specifics of InstallShield logging.

Using the cached MSI database in the super hidden cache folder
get-wmiobject Win32_Product | Format-Table Name, LocalPackage -AutoSize
Using
PowerShell
There is a similar, but more comprehensive PowerShell script available on MSDN. It allows uninstall to be run on several machines.
Entry added by Even Mien:
$app = Get-WmiObject -Class Win32_Product -Filter "Name = 'YOUR_APP'"
$app.Uninstall()
This approach will work, but accessing the WMI class Win32_Product will trigger a software consistency check which is very slow and in special circumstances it can cause an MSI self-repair to be triggered. See this article: Powershell Uninstall Script - Have a real headache
I have not tested this myself, but it appears $app.Uninstall() may run the UninstallString registered in the ARP applet's registry settings. This means it may run modify instead of uninstall in some cases.
Check this topic for more details and ways to uninstall via Powershell: How can I uninstall an application using PowerShell?
Using the .NET DTF Class Library
(part of the WiX toolkit) using Microsoft.Deployment.WindowsInstaller;
public static void Uninstall( string productCode)
{
Installer.ConfigureProduct(productCode, 0, InstallState.Absent, "REBOOT=\"R\"");
}
Using the
Windows Installer Automation API
Here is a community discussion of this option: Windows Installer Automation API community sample
The API can be accessed via script automation and C++ API calls (my post on serverfault.com)
The following source adapted from MSI expert Christopher Painter using VBScript:
Set installer = CreateObject("WindowsInstaller.Installer")
installer.InstallProduct "product.msi", "REMOVE=ALL REBOOT=ReallySuppress"
Set installer = Nothing

Using a
Windows Installer major upgrade
Using Deployment Systems / Remote Administration Systems
Using WMI - Windows Management Instrumentation
Win32_Product.Install
Win32_Product.Uninstall
Using a third-party tool such as
ccleaner
or similar
Using a cleanup tool such as
msizap
or similar
Using
system restore
("installation undo" - last resort IMHO)
Windows Installer Functions (C++)
For completeness I guess we should mention the core of it all - the down-to-the-metal way: the Win32 Windows Installer API functions. These are likely the functions used by most, if not all of the other approaches listed above "under the hood". They are primarily used by applications or solutions dealing directly with MSI as a technology.

No, this will cause the exception to have a different stack trace. Only using a throw

handler will leave the stack trace unchanged.
You may want to return a boolean from HandleException whether the exception shall be rethrown or not.
I just recently started learning XML. The underscore version helps me separate everything XML-related (DOM, XSD, etc.) from programming languages like Java, JavaScript (camel case). And I agree with you that using identifiers which are allowed in programming languages looks better.
Edit: Might be unrelated, but here is a link for rules and recommendations on naming XML elements which I follow when naming ids (sections "XML Naming Rules" and "Best Naming Practices").
I find that if you're familiar with SQL syntax, using the LINQ query syntax is much clearer, more natural, and makes it easier to spot errors:
var id = 1;
var query =
from post in database.Posts
join meta in database.Post_Metas on post.ID equals meta.Post_ID
where post.ID == id
select new { Post = post, Meta = meta };
If you're really stuck on using lambdas though, your syntax is quite a bit off. Here's the same query, using the LINQ extension methods:
var id = 1;
var query = database.Posts // your starting point - table in the "from" statement
.Join(database.Post_Metas, // the source table of the inner join
post => post.ID, // Select the primary key (the first part of the "on" clause in an sql "join" statement)
meta => meta.Post_ID, // Select the foreign key (the second part of the "on" clause)
(post, meta) => new { Post = post, Meta = meta }) // selection
.Where(postAndMeta => postAndMeta.Post.ID == id); // where statement
Mainly you need to delete duplicate adb.exe file. You can use Everything to Find.
keep the platform-tools adb.exe
and add the platform-tools directory to your Environment Path Variable.
I am using Memu Emulator.
So, I have taken these steps:
Go to Memu Installation Directory: (In My Case D:\Program Files\Microvirt\MEmu)
And then Delete the adb.exe file.
It should work fine for you.
It has ability to convert HTML file in to pdf.
Required namespace for conversions are:
using iTextSharp.text;
using iTextSharp.text.pdf;
and for conversion and download file :
// Create a byte array that will eventually hold our final PDF
Byte[] bytes;
// Boilerplate iTextSharp setup here
// Create a stream that we can write to, in this case a MemoryStream
using (var ms = new MemoryStream())
{
// Create an iTextSharp Document which is an abstraction of a PDF but **NOT** a PDF
using (var doc = new Document())
{
// Create a writer that's bound to our PDF abstraction and our stream
using (var writer = PdfWriter.GetInstance(doc, ms))
{
// Open the document for writing
doc.Open();
string finalHtml = string.Empty;
// Read your html by database or file here and store it into finalHtml e.g. a string
// XMLWorker also reads from a TextReader and not directly from a string
using (var srHtml = new StringReader(finalHtml))
{
// Parse the HTML
iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml);
}
doc.Close();
}
}
// After all of the PDF "stuff" above is done and closed but **before** we
// close the MemoryStream, grab all of the active bytes from the stream
bytes = ms.ToArray();
}
// Clear the response
Response.Clear();
MemoryStream mstream = new MemoryStream(bytes);
// Define response content type
Response.ContentType = "application/pdf";
// Give the name of file of pdf and add in to header
Response.AddHeader("content-disposition", "attachment;filename=invoice.pdf");
Response.Buffer = true;
mstream.WriteTo(Response.OutputStream);
Response.End();
My personal approach, which seems to work for all cases, is testing for the presence of members that will all only be present for strings.
function isString(x) {
return (typeof x == 'string' || typeof x == 'object' && x.toUpperCase && x.substr && x.charAt && x.trim && x.replace ? true : false);
}

I'd like to know if this method has flaws, but it has served me well for years.
That is because, of course, there is no ACTUAL page height. Keep in mind that you scroll throughout the contents of a page vertically not horizontally, creating a limited width but unlimited height. What the selected answer did was to make the table take up the visible area and stay there no matter what(absolute positioning).So theoretically what you were trying to do was impossible
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
var height:CGFloat = CGFloat()
if indexPath.row == 1 {
height = 150
}
else {
height = 50
}
return height
}
Java 8 introduces the Instant.ofEpochSecond
utility method for creating an Instant
from a Unix timestamp, this can then be converted into a ZonedDateTime
and finally formatted, e.g.:
final DateTimeFormatter formatter =
DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
final long unixTime = 1372339860;
final String formattedDtm = Instant.ofEpochSecond(unixTime)
.atZone(ZoneId.of("GMT-4"))
.format(formatter);
System.out.println(formattedDtm); // => '2013-06-27 09:31:00'
I thought this might be useful for people who are using Java 8.
Do it simply by adding a class to the body:
.stop-scrolling {
height: 100%;

Add the class then remove when you want to re-enable scrolling, tested in IE, FF, Safari and Chrome.
$('body').addClass('stop-scrolling')
For mobile devices, you'll need to handle the touchmove
event:
$('body').bind('touchmove', function(e){e.preventDefault()})
And unbind to re-enable scrolling. Tested in iOS6 and Android 2.3.3
$('body').unbind('touchmove')
I’ll try to answer the actual question of what a stack is.
In the Internet architecture (TCP/IP, OSI, etc.), protocols and software are often “stacked” on top of each other, as they depend on each other for support. For example, TCP provides reliable transmissions of data, on top of IP. The same goes for LAMP, your Apache server needs to run “on top of Linux”. Think of this “stack” as your favorite stack of pancakes, where each pancake is a different layer.
Yummy.
You can try following code snippet.
function addScript(attribute, text, callback) {
var s = document.createElement('script');
for (var attr in attribute) {
s.setAttribute(attr, attribute[attr] ? attribute[attr] : null)
}
s.innerHTML = text;
s.onload = callback;
document.body.appendChild(s);
}
addScript({
src: 'https://www.google.com',
type: 'text/javascript',
async: null
}, '<div>innerHTML</div>', function(){});
If you know the height of the div you want to center, you can position it absolutely within its parent and then set the top
value to 50%
. That will put the top of the child div 50% of the way down its parent, i.e. too low. Pull it back up by setting its margin-top
to half its height. So now you have the vertical midpoint of the child div sitting at the vertical midpoint of the parent - vertically centered!
Example:
.black {_x000D_
position:absolute;_x000D_
top:0;_x000D_
bottom:0;_x000D_
left:0;_x000D_
right:0;_x000D_
background:rgba(0,0,0,.5);_x000D_
}_x000D_
.message {_x000D_
background:yellow;_x000D_
width:200px;_x000D_
margin:auto auto;_x000D_
padding:10px;_x000D_
position: absolute;_x000D_
top: 50%;_x000D_
margin-top: -25px;_x000D_
height: 50px;_x000D_
}
_x000D_
<div class="black">_x000D_
<div class="message">_x000D_
This is a popup message._x000D_
</div>_x000D_
</div>
_x000D_
You may do a session and place it:
// Start session
session_start();
// Check do the person logged in
if($_SESSION['username']==NULL){
// Haven't log in
echo "You haven't log in";
}else{
// Logged in
echo "Successfully logged in!";
}
Note: you must make a form which contain $_SESSION['username'] = $login_input_username;
For System.Timers.Timer:
See Brian Gideon's answer below
MSDN Documentation on Timers states:
The System.Threading.Timer class makes callbacks on a ThreadPool thread and does not use the event model at all.
So indeed the timer elapses on a different thread.
In Python 2.x, just use the ord
and chr
functions:
>>> ord('c')
99
>>> ord('c') + 1
100
>>> chr(ord('c') + 1)
'd'
>>>
Python 3.x makes this more organized and interesting, due to its clear distinction between bytes and unicode. By default, a "string" is unicode, so the above works (ord
receives Unicode chars and chr
produces them).
But if you're interested in bytes (such as for processing some binary data stream), things are even simpler:
>>> bstr = bytes('abc', 'utf-8')
>>> bstr
b'abc'
>>> bstr[0]
97
>>> bytes([97, 98, 99])
b'abc'
>>> bytes([bstr[0] + 1, 98, 99])
b'bbc'
If you are exporting another class in that module, make sure that it is not in between @Component
and your ClassComponent
. For example:
@Component({ ... })
export class ExampleClass{}
export class ComponentClass{} --> this will give this error.
FIX:
export class ExampleClass{}
@Component ({ ... })
export class ComponentClass{}

pytest constantly evolves and with one of the nice changes in the recent past it is now possible to simultaneously test for
Two examples from the documentation:
with pytest.raises(ValueError, match='must be 0 or None'):
raise ValueError('value must be 0 or None')
with pytest.raises(ValueError, match=r'must be \d+$'):
raise ValueError('value must be 42')
I have been using that approach in a number of projects and like it very much.
If you are facing this issue while pushing changes in big size then run below command in terminal.
git config --global http.postBuffer 157286400
See this for more details.
Len won't yield the total number of objects in a nested list (including multidimensional lists). If you have numpy
, use size()
. Otherwise use list comprehensions within recursion.
No such thing, probably just a macro for int
You can use the index
method
ints = [8, 23, 45, 12, 78]
inds = [ints.index(i) for i in ints]
EDIT
Highlighted in the comment that this method doesn’t work if there are duplicates in ints
, the method below should work for any values in ints
:
ints = [8, 8, 8, 23, 45, 12, 78]
inds = [tup[0] for tup in enumerate(ints)]
Or alternatively
ints = [8, 8, 8, 23, 45, 12, 78]
inds = [tup for tup in enumerate(ints)]
if you want to get both the index and the value in ints
as a list of tuples.
It uses the method of enumerate
in the selected answer to this question, but with list comprehension, making it faster with less code.
I do it in Kotlin like this:
open class BaseAppCompatActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {
protected lateinit var drawerLayout: DrawerLayout
protected lateinit var navigationView: NavigationView
@Inject
lateinit var loginService: LoginService
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
Log.d("BaseAppCompatActivity", "onCreate()")
App.getComponent().inject(this)
drawerLayout = findViewById(R.id.drawer_layout) as DrawerLayout
val toolbar = findViewById(R.id.toolbar) as Toolbar
setSupportActionBar(toolbar)
navigationView = findViewById(R.id.nav_view) as NavigationView
navigationView.setNavigationItemSelectedListener(this)
val toggle = ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
drawerLayout.addDrawerListener(toggle)
toggle.syncState()
toggle.isDrawerIndicatorEnabled = true
val navigationViewHeaderView = navigationView.getHeaderView(0)
navigationViewHeaderView.login_txt.text = SharedKey.username
}
private inline fun <reified T: Activity> launch():Boolean{
if(this is T) return closeDrawer()
val intent = Intent(applicationContext, T::class.java)
startActivity(intent)
finish()
return true
}
private fun closeDrawer(): Boolean {
drawerLayout.closeDrawer(GravityCompat.START)
return true
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
val id = item.itemId
when (id) {
R.id.action_tasks -> {
return launch<TasksActivity>()
}
R.id.action_contacts -> {
return launch<ContactActivity>()
}
R.id.action_logout -> {
createExitDialog(loginService, this)
}
}
return false
}
}
Activities for drawer must inherit this BaseAppCompatActivity
, call super.onCreate
after content is set (actually, can be moved to some init method) and have corresponding elements for ids in their layout
Nowadays we have to use match_parent
:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/background">
</RelativeLayout>
This can be done from the command line. This will create a column for your image with a NOT NULL
property.
CREATE TABLE `test`.`pic` (
`idpic` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
`caption` VARCHAR(45) NOT NULL,
`img` LONGBLOB NOT NULL,
PRIMARY KEY(`idpic`)
)
TYPE = InnoDB;
From here
I think it's best highlighted with an example. If you feel you could write the following SQL statement quickly with little/no reference material, then I'd guess that you probably meet their Advanced SQL requirement:
DECLARE @date DATETIME
SELECT @date = '10/31/09'
SELECT
t1.EmpName,
t1.Region,
t1.TourStartDate,
t1.TourEndDate,
t1.FOrdDate,
FOrdType = MAX(CASE WHEN o.OrderDate = t1.FOrdDate THEN o.OrderType ELSE NULL END),
FOrdTotal = MAX(CASE WHEN o.OrderDate = t1.FOrdDate THEN o.OrderTotal ELSE NULL END),
t1.LOrdDate,
LOrdType = MAX(CASE WHEN o.OrderDate = t1.LOrdDate THEN o.OrderType ELSE NULL END),
LOrdTotal = MAX(CASE WHEN o.OrderDate = t1.LOrdDate THEN o.OrderTotal ELSE NULL END)
FROM
(--Derived table t1 returns the tourdates, and the order dates
SELECT
e.EmpId,
e.EmpName,
et.Region,
et.TourStartDate,
et.TourEndDate,
FOrdDate = MIN(o.OrderDate),
LOrdDate = MAX(o.OrderDate)
FROM #Employees e INNER JOIN #EmpTours et
ON e.EmpId = et.EmpId INNER JOIN #Orders o
ON e.EmpId = o.EmpId
WHERE et.TourStartDate <= @date
AND (et.TourEndDate > = @date OR et.TourEndDate IS NULL)
AND o.OrderDate BETWEEN et.TourStartDate AND @date
GROUP BY e.EmpId,e.EmpName,et.Region,et.TourStartDate,et.TourEndDate
) t1 INNER JOIN #Orders o
ON t1.EmpId = o.EmpId
AND (t1.FOrdDate = o.OrderDate OR t1.LOrdDate = o.OrderDate)
GROUP BY t1.EmpName,t1.Region,t1.TourStartDate,t1.TourEndDate,t1.FOrdDate,t1.LOrdDate
And to be honest, that's a relatively simple query - just some inner joins and a subquery, along with a few common keywords (max, min, case).
The sample above worked like a charm. I just did a modification just in case I need to manage multiple values. I hope this helps!
app.service('sharedProperties', function () {
var hashtable = {};
return {
setValue: function (key, value) {
hashtable[key] = value;
},
getValue: function (key) {
return hashtable[key];
}
}
});
use
SELECT DISTINCT Date FROM buy ORDER BY Date
so MySQL removes duplicates
BTW: using explicit column names in SELECT
uses less resources in PHP when you're getting a large result from MySQL
It is sometimes convenient to employ the "send/recv" family of system calls. If the flags
parameter contains the MSG_DONTWAIT
flag, each call will behave similar to a socket having the O_NONBLOCK
flag set.
ssize_t send(int sockfd, const void *buf, size_t len, int flags);
ssize_t recv(int sockfd, void *buf, size_t len, int flags);
Adding more to Jason's more generalized way of retrieving the POST data or GET data
from flask_restful import reqparse
def parse_arg_from_requests(arg, **kwargs):
parse = reqparse.RequestParser()
parse.add_argument(arg, **kwargs)
args = parse.parse_args()
return args[arg]
form_field_value = parse_arg_from_requests('FormFieldValue')
You can use expand.grid( ) function.
x <-c(1,2,3)
y <-c(100,200,300)
expand.grid(cond=x,rating=y)
VARCHAR(255)
and VARCHAR(2)
take exactly the same amount of space on disk! So the only reason to limit it is if you have a specific need for it to be smaller. Otherwise make them all 255.
Specifically, when doing sorting, larger column do take up more space, so if that hurts performance, then you need to worry about it and make them smaller. But if you only ever select 1 row from that table, then you can just make them all 255 and it won't matter.
I don't think one needs it any more. The latest versions of Eclipse have Maven plugin enabled. So you will just need to import a Maven project into Eclipse and no more as an existing project. Eclipse will create the needed .project, .settings, .classpath files based on your pom.xml and environment settings (installed Java version, etc.) . The earlier versions of Eclipse needed to have run the command mvn eclipse:eclipse
which produced the same result.
What about using the change event of Jquery?
$(function() {

} else {
alert("You selected the second option and deselected the first one");
}
});

The updatePolicy tag didn't work for me. However Rich Seller mentioned that snapshots should be disabled anyways so I looked further and noticed that the extra repository that I added to my settings.xml was causing the problem actually. Adding the snapshots section to this repository in my settings.xml did the trick!

Where 'password' is your new password. In-between quotes.
GO to your browser and visit link http://localhost/phpmyadmin/. Click on 'GO' without your new password. It would log you in and you would be able to see the "CHANGE PASSWORD". Proceed to change your password and you are done.

If you mean cast a String to int, use Integer.valueOf("123")
.
You can't cast most other Objects to int though, because they wont have an int value. E.g. an XmlDocument has no int value.
You are not supposed to assign it to any variable, when you append something in the list, it updates automatically. use only:-
last_list.append(p.last)
if you assign this to a variable "last_list" again, it will no more be a list (will become a none type variable since you haven't declared the type for that) and append will become invalid in the next run.
You will get this error when you call any of the setXxx()
methods on PreparedStatement
, while the SQL query string does not have any placeholders ?
for this.
For example this is wrong:
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (val1, val2, val3)";
// ...
preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1); // Fail.
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);
You need to fix the SQL query string accordingly to specify the placeholders.
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (?, ?, ?)";
// ...
preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1);
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);
Note the parameter index starts with 1
and that you do not need to quote those placeholders like so:
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES ('?', '?', '?')";
Otherwise you will still get the same exception, because the SQL parser will then interpret them as the actual string values and thus can't find the placeholders anymore.
To anyone still looking for an answer:

For completeness, write_csv()
from the readr
package is faster and never writes row names
# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")
If you need to write big data out, use fwrite()
from the data.table
package. It's much faster than both write.csv
and write_csv
# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")
Below is a benchmark that Edouard published on his site
microbenchmark(write.csv(data, "baseR_file.csv", row.names = F),

Of the 4 shells that I've tested, ABC -eq XYZ
evaluates to true in the test
builtin for zsh
and ksh
. The expression evaluates to false under /usr/bin/test
and the builtins for dash
and bash
. In ksh
and zsh
, the strings are converted to numerical values and are equal since they are both 0. IMO, the behavior of the builtins for ksh
and zsh
is incorrect, but the spec for test
is ambiguous on this.

Take double array as an example, if the initial input values

values[0] = 0.0;
}
for (int i = 1; i < len; i += i) {
System.arraycopy(values, 0, values, i, ((len - i) < i) ? (len - i) : i);
}

My piece: nodejs is great for making real time systems like analytics, chat-apps, apis, ad servers, etc. Hell, I made my first chat app using nodejs and socket.io under 2 hours and that too during exam week!
Edit
Its been several years since I have started using nodejs and I have used it in making many different things including static file servers, simple analytics, chat apps and much more. This is my take on when to use nodejs
When to use
When making system which put emphasis on concurrency and speed.
When not to use
Its a very versatile webserver so you can use it wherever you want but probably not these places.
Keep in mind that I am just nitpicking. For static file servers, apache is better mainly because it is widely available. The nodejs community has grown larger and more mature over the years and it is safe to say nodejs can be used just about everywhere if you have your own choice of hosting.
A code like that should work:
int i = 0;
char string[256], c;
while(i < 256 - 1 && (c = fgetc(fp) != EOF)) //Keep space for the final \0
{
string[i++] = c;
}
string[i] = '\0';
You are close you want to use @Html.Raw(str)

Since the question on how to set fields mandatory pops up under each post, I wrote a small example on how to set fields as required:
public class ExampleDTO {
@NotNull
private String mandatoryParam;
private String optionalParam;
@DateTimeFormat(iso = ISO.DATE) //accept Dates only in YYYY-MM-DD
@NotNull
private LocalDate testDate;
public String getMandatoryParam() {
return mandatoryParam;
}
public void setMandatoryParam(String mandatoryParam) {
this.mandatoryParam = mandatoryParam;
}
public String getOptionalParam() {
return optionalParam;
}
public void setOptionalParam(String optionalParam) {
this.optionalParam = optionalParam;
}
public LocalDate getTestDate() {
return testDate;
}
public void setTestDate(LocalDate testDate) {
this.testDate = testDate;
}
}
//Add this to your rest controller class
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String testComplexObject (@Valid ExampleDTO e){
System.out.println(e.getMandatoryParam() + " " + e.getTestDate());
return "Does this work?";
}

Using only CSS it is not possible at all to add links :) It is not possible to link a background-image, nor a part of it, using HTML/CSS. However, it can be staged using this method:

</div>
.wrapWithBackgroundImage {
background-image: url(...);
}
.invisibleLink {
display: block;
left: 55px; top: 55px;

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-
doNothing().when(InternalUtils.class); //This is the preferred way
//to mock static void methods.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.
mockStatic(Internalutils.class);
So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.
@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {
@Mock
private InternalService.Order order;
private InternalService internalService;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
internalService = new InternalService();
}
@Test
public void processOrder() throws Exception {
Mockito.when(order.isSuccessful()).thenReturn(true);
PowerMockito.mockStatic(InternalService.InternalUtils.class);
internalService.processOrder(order);
PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
}
}
These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.
PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
This is code of my class, sendEmail api twice.
public class InternalService {
public void processOrder(Order order) {
if (order.isSuccessful()) {
InternalUtils.sendEmail("", new String[1], "", "");
InternalUtils.sendEmail("", new String[1], "", "");
}
}
public static class InternalUtils{
public static void sendEmail(String from, String[] to, String msg, String body){
}
}
public class Order{
public boolean isSuccessful(){
return true;
}
}
}
As it is calling twice you just need to change the verify(times(2))... that's all.
You can't pass str
to your model fit()

alignSelf: 'center',

}}>
<Text style={{ top: 0, alignSelf: 'center' }} >{image.title}</Text>
<Text style={{ alignSelf: 'center' }}>{image.description}</Text>
</View>
Along with Yoshi's answer, I have found another very simple (callback type) solution for animations.
jQuery has an exposed variable (that for some reason isn't listed anywhere in the jQuery docs) called $.timers, which holds the array of animations currently taking place.
function animationsTest (callback) {
// Test if ANY/ALL page animations are currently active
var testAnimationInterval = setInterval(function () {
if (! $.timers.length) { // any page animations finished
clearInterval(testAnimationInterval);
callback();
}
}, 25);
};
Basic useage:
functionOne(); // one with animations
animationsTest(functionTwo);
Hope this helps some people out!

func = K.function([model.get_layer(index=0).input], model.get_layer(index=layerIndex).output)
layerOutput = func([input_data]) # input_data is a numpy array
print(layerOutput)
To print output of every layer:
from tensorflow.keras import backend as K
for layerIndex, layer in enumerate(model.layers):
func = K.function([model.get_layer(index=0).input], layer.output)
layerOutput = func([input_data]) # input_data is a numpy array
print(layerOutput)
Edit: use
<=
or>=
to count today's date.
This is the right answer for your code. Just use the strtotime() php function.
$paymentDate = date('Y-m-d');
$paymentDate=date('Y-m-d', strtotime($paymentDate));
//echo $paymentDate; // echos today!
$contractDateBegin = date('Y-m-d', strtotime("01/01/2001"));
$contractDateEnd = date('Y-m-d', strtotime("01/01/2012"));
if (($paymentDate >= $contractDateBegin) && ($paymentDate <= $contractDateEnd)){
echo "is between";
}else{
echo "NO GO!";
}
You can use the built-in CSS class pre-scrollable in bootstrap 3 inside the span element of the dropdown and it works immediately without implementing custom css.
<ul class="dropdown-menu pre-scrollable">
<li>item 1 </li>
<li>item 2 </li>
</ul>
For those who are looking for pure javascript solution
document.getElementById(location.hash.substring(1)).style.display = 'block'
Hope this saves you some time.
The static code block can be used to instantiate or initialize class variables (as opposed to object variables). So declaring "a" static means that is only one shared by all Test objects, and the static code block initializes "a" only once, when the Test class is first loaded, no matter how many Test objects are created.
Use
datatable.select("col1='test'","col1 ASC")
Then before binding your data to the grid or repeater etc, use this
datatable.defaultview.sort()
That will solve your problem.
If you take a look at the source code of Spring Data JPA, and particularly the PartTreeJpaQuery
class, you will see that is tries to instantiate PartTree
.
Inside that class the following regular expression
private static final Pattern PREFIX_TEMPLATE = Pattern.compile("^(find|read|get|count|query)(\\p{Lu}.*?)??By")
should indicate what is allowed and what's not.
Of course if you try to add such a method you will actually see that is does not work and you get the full stacktrace.
I should note that I was using looking at version 1.5.0.RELEASE
of Spring Data JPA
If there is other content not being shown inside the outer-div (the green box), why not have that content wrapped inside another div, let's call it "content"
. Have overflow hidden on this new inner-div, but keep overflow visible on the green box.
The only catch is that you will then have to mess around to make sure that the content div doesn't interfere with the positioning of the red box, but it sounds like you should be able to fix that with little headache.
<div id="1" background: #efe; padding: 5px; width: 125px">
<div id="content" style="overflow: hidden;">
</div>
<div id="2" style="position: relative; background: #fee; padding: 2px; width: 100px; height: 100px">
<div id="3" style="position: absolute; top: 10px; background: #eef; padding: 2px; width: 75px; height: 150px"/>
</div>
</div>
I would seriously consider the Occam's Razor approach here:
td = str(timedelta).split('.')[0]
This returns a string without the microseconds
If you want to regenerate the datetime.timedelta object, just do this:
h,m,s = re.split(':', td)
new_delta = datetime.timedelta(hours=int(h),minutes=int(m),seconds=int(s))
2 years in, I love this language!
From Microsoft.PowerShell.Archive
you can use:
E.g.:
Create result.zip
from the entire Test
folder:
Compress-Archive -Path C:\Test -DestinationPath C:\result
Extract the content of result.zip
in the specified Test
folder:
Expand-Archive -Path result.zip -DestinationPath C:\Test
Use defaultValue and onChange like this
const [myValue, setMyValue] = useState('');
<select onChange={(e) => setMyValue(e.target.value)} defaultValue={props.myprop}>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
The component type of containers like vectors must be assignable. References are not assignable (you can only initialize them once when they are declared, and you cannot make them reference something else later). Other non-assignable types are also not allowed as components of containers, e.g. vector<const int>
is not allowed.
ALTER TABLE table_name ALTER COLUMN id SET DEFAULT uuid_in((md5((random())::text))::cstring);
After reading @ZuzEL's answer, i used the above code as the default value of the column id and it's working fine.
CriteriaBuilder criteriaBuilder = em.getCriteriaBuilder();
CriteriaQuery<Employee> criteriaQuery = criteriaBuilder.createQuery(Employee.class);
Root<Employee> empleoyeeRoot = criteriaQuery.from(Employee.class);
Subquery<Project> projectSubquery = criteriaQuery.subquery(Project.class);
Root<Project> projectRoot = projectSubquery.from(Project.class);
projectSubquery.select(projectRoot);
Expression<String> stringExpression = empleoyeeRoot.get(Employee_.ID);
Predicate predicateIn = stringExpression.in(projectSubquery);
criteriaQuery.select(criteriaBuilder.count(empleoyeeRoot)).where(predicateIn);
you can use a generator:
li = [1,2,3,4,5,6]
len_li = len(li)
gen = (len_li-1-i for i in range(len_li))
finally:
for i in gen:
print(li[i])
hope this help you.
From the manual:
If the database server successfully prepares the statement, PDO::prepare() returns a PDOStatement object. If the database server cannot successfully prepare the statement, PDO::prepare() returns FALSE or emits PDOException (depending on error handling).
The prepare statement likely caused an error because the db would be unable to prepare the statement. Try testing for an error immediately after you prepare your query and before you execute it.
$qry = '
INSERT INTO non-existant-table (id, score)
SELECT id, 40
FROM another-non-existant-table
WHERE description LIKE "%:search_string%"
AND available = "yes"
ON DUPLICATE KEY UPDATE score = score + 40
';
$sth = $this->pdo->prepare($qry);
print_r($this->pdo->errorInfo());
You need to use -I
with each directory. But you can still delimit the directories with whitespace if you use (GNU) make's foreach
:
INC=$(DIR1) $(DIR2) ...
INC_PARAMS=$(foreach d, $(INC), -I$d)
$x
is always a scalar. The hint is the sigil $
: any variable (or dereferencing of some other type) starting with $
is a scalar. (See perldoc perldata for more about data types.)
A reference is just a particular type of scalar.
The built-in function ref
will tell you what kind of reference it is. On the other hand, if you have a blessed reference, ref
will only tell you the package name the reference was blessed into, not the actual core type of the data (blessed references can be hashrefs, arrayrefs or other things). You can use Scalar::Util 's reftype
will tell you what type of reference it is:
use Scalar::Util qw(reftype);
my $x = bless {}, 'My::Foo';
my $y = { };
print "type of x: " . ref($x) . "\n";
print "type of y: " . ref($y) . "\n";
print "base type of x: " . reftype($x) . "\n";
print "base type of y: " . reftype($y) . "\n";
...produces the output:
type of x: My::Foo
type of y: HASH
base type of x: HASH
base type of y: HASH
For more information about the other types of references (e.g. coderef, arrayref etc), see this question: How can I get Perl's ref() function to return REF, IO, and LVALUE? and perldoc perlref.
Note: You should not use ref
to implement code branches with a blessed object (e.g. $ref($a) eq "My::Foo" ? say "is a Foo object" : say "foo not defined";
) -- if you need to make any decisions based on the type of a variable, use isa
(i.e if ($a->isa("My::Foo") { ...
or if ($a->can("foo") { ...
). Also see polymorphism.
The library considers making the path set as C:\Program Files\ATT\Graphviz\bin but by default Graphviz is installed to C:\Program Files(x86)\Graphviz undergoing the 32-bit criteria hence the pydot fails in getting the required path. Simply shift the directory as required by the script and you're good to go.
P.S.:- Consider making the equivalent changes to the Environmnet Variable.
P.S.S:- Also check if Graphviz is directly under Program Files(x86) or under ATT.
There is a limitation in SQL Server (up till 2008 R2) that varchar(MAX) and nvarchar(MAX) (and several other types like text, ntext ) cannot be used in indices. You have 2 options:
1. Set a limited size on the key field ex. nvarchar(100)
2. Create a check constraint that compares the value with all the keys in the table.
The condition is:
([dbo].[CheckKey]([key])=(1))
and [dbo].[CheckKey] is a scalar function defined as:
CREATE FUNCTION [dbo].[CheckKey]
(
@key nvarchar(max)
)
RETURNS bit
AS
BEGIN
declare @res bit
if exists(select * from key_value where [key] = @key)
set @res = 0
else
set @res = 1
return @res
END
But note that a native index is more performant than a check constraint so unless you really can't specify a length, don't use the check constraint.
int max = 50;
int min = 1;
double random = Math.random() * 49 + 1;
or
int random = (int )(Math.random() * 50 + 1);
This will give you value from 1 to 50 in case of int or 1.0 (inclusive) to 50.0 (exclusive) in case of double
Why?
random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches.
Random rand = new Random();
int value = rand.nextInt(50);
This will give value from 0 to 49.
For 1 to 50: rand.nextInt((max - min) + 1) + min;

while(in.hasNextLine())
{
in.nextLine();
lines++;

Checkout this thread, it has some useful information about exiting and tracebacks.
If you are more interested in just killing the program, try something like this (this will take the legs out from under the cleanup code as well):
if __name__ == '__main__':
try:
main()
except KeyboardInterrupt:
print('Interrupted')
try:
sys.exit(0)
except SystemExit:
os._exit(0)
Modify your log4j.properties
file accordingly:
log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog
Change the log levels for each logger depending to your needs.
The HTML5 form validation process is limited to situations where the form is being submitted via a submit button. The Form submission algorithm explicitly says that validation is not performed when the form is submitted via the submit()
method. Apparently, the idea is that if you submit a form via JavaScript, you are supposed to do validation.
However, you can request (static) form validation against the constraints defined by HTML5 attributes, using the checkValidity()
method. If you would like to display the same error messages as the browser would do in HTML5 form validation, I’m afraid you would need to check all the constrained fields, since the validityMessage
property is a property of fields (controls), not the form. In the case of a single constrained field, as in the case presented, this is trivial of course:
function submitform() {
var f = document.getElementsByTagName('form')[0];
if(f.checkValidity()) {
f.submit();
} else {
alert(document.getElementById('example').validationMessage);
}
}

In standard Markdown, place an anchor <a name="abcd"></a>
where you want to link to and refer to it on the same page by [link text](#abcd)
.
(This uses name=
and not id=
, for reasons explained in this answer.)
Remote references can use [link text](http://...#abcd)
of course.
This works like a dream, provided you have control over the source and target texts. The anchor can even appear in a heading, thus:
### <a name="head1234"></a>A Heading in this SO entry!
produces:
and we can even link to it so:
and we can even [link](#head1234) to it so:
(On SO, the link doesn't work because the anchor is stripped.)
You can use also in the php file like this
<?php ini_set('upload_max_filesize', '200M'); ?>
Similar to Dictionary Collection point of view, I have done this.
Dictionary<string, bool> sourceDict = new Dictionary<string, bool>();
sourceDict.Add("Sai", true);
sourceDict.Add("Sri", false);
sourceDict.Add("SaiSri", true);
sourceDict.Add("SaiSriMahi", true);
var itemsToDelete = sourceDict.Where(DictItem => DictItem.Value == false);
foreach (var item in itemsToDelete)
{
sourceDict.Remove(item.Key);
}
Note: Above code will fail in .Net Client Profile (3.5 and 4.5) also some viewers mentioned it is Failing for them in .Net4.0 as well not sure which settings are causing the problem.
So replace with below code (.ToList()) for Where statement, to avoid that error. “Collection was modified; enumeration operation may not execute.”
var itemsToDelete = sourceDict.Where(DictItem => DictItem.Value == false).ToList();
Per MSDN From .Net4.5 onwards Client Profile are discontinued. http://msdn.microsoft.com/en-us/library/cc656912(v=vs.110).aspx
echo "<p><a href=\"javascript:history.go(-1)\" title=\"Return to previous page\">«Go back</a></p>";
Will go back one page.
echo "<p><a href=\"javascript:history.go(-2)\" title=\"Return to previous page\">«Go back</a></p>";
Will go back two pages.
You can use it without doing anything special. If you have a local image called blah
you can do FROM blah
. If you do FROM blah
in your Dockerfile, but don't have a local image called blah
, then Docker will try to pull it from the registry.
In other words, if a Dockerfile does FROM ubuntu
, but you have a local image called ubuntu
different from the official one, your image will override it.
It's also possible to use java Foo | tee -a some.log
. it just prints to stdout as well. Like:
user at Computer in ~
$ echo "hi" | tee -a foo.txt
hi
user at Computer in ~
$ echo "hello" | tee -a foo.txt
hello
user at Computer in ~
$ cat foo.txt
hi
hello
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"/>
If you want to read that file from inside your application use:
InputStream input = getClass().getResourceAsStream("/classpath/to/my/file");
The path starts with "/", but that is not the path in your file-system, but in your classpath. So if your file is at the classpath "org.xml" and is called myxml.xml your path looks like "/org/xml/myxml.xml".
The InputStream reads the content of your file. You can wrap it into an Reader, if you want.
I hope that helps.
That means that your consumer is expecting XML from the webservice but the webservice, as your error shows, returns HTML because it's failing due to a timeout.
So you need to talk to the remote webservice provider to let them know it's failing and take corrective action. Unless you are the provider of the webservice in which case you should catch the exceptions and return XML telling the consumer which error occurred (the 'remote provider' should probably do that as well).
There is a better way to write polar(), here it is:
def polar(x,y):
`returns r, theta(degrees)`
return math.hypot(x,y),math.degrees(math.atan2(y,x))
Your code is working at my end, i have just tested it. Where are you checking your changes? Use Documents directory path. To get path -
NSLog(@"%@",documentsDirectory);
and copy path from console and then open finder and press Cmd+shift+g and paste path here and then open your file
