Based on the answer by Ryan Shillington, modified to work with strings longer than 255 characters and preserving spaces from the original string.
FYI there is lower(str)
in the end.
I used this to compare strings:
DROP FUNCTION IF EXISTS spacealphanum;
DELIMITER $$
CREATE FUNCTION `spacealphanum`( str TEXT ) RETURNS TEXT CHARSET utf8
BEGIN
DECLARE i, len SMALLINT DEFAULT 1;
DECLARE ret TEXT DEFAULT '';
DECLARE c CHAR(1);
SET len = CHAR_LENGTH( str );
REPEAT
BEGIN
SET c = MID( str, i, 1 );
IF c REGEXP '[[:alnum:]]' THEN
SET ret=CONCAT(ret,c);
ELSEIF c = ' ' THEN
SET ret=CONCAT(ret," ");
END IF;
SET i = i + 1;
END;
UNTIL i > len END REPEAT;
SET ret = lower(ret);
RETURN ret;
END $$
DELIMITER ;
It was my regex: @"^(?=.{3,15}$)(?:(?:\p{L}|\p{N})[._()\[\]-]?)*$"
I just added ([\w ]+)
at the end of my regex before *
@"^(?=.{3,15}$)(?:(?:\p{L}|\p{N})[._()\[\]-]?)([\w ]+)*$"
Now string is allowed to have spaces.
C99 standard on c >= '0' && c <= '9'
c >= '0' && c <= '9'
(mentioned in another answer) works because C99 N1256 standard draft 5.2.1 "Character sets" says:
In both the source and execution basic character sets, the value of each character after 0 in the above list of decimal digits shall be one greater than the value of the previous.
ASCII is not guaranteed however.

public class alphanumeric {
public static void main(String args[]) {
String nval, lenval;
int n, len;
nval = JOptionPane.showInputDialog("Enter number of codes you require: ");
n = Integer.parseInt(nval);
lenval = JOptionPane.showInputDialog("Enter code length you require: ");
len = Integer.parseInt(lenval);
find(n, len);
}
public static void find(int n, int length) {
String str1 = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
StringBuilder sb = new StringBuilder(length);
Random r = new Random();
System.out.println("\n\t Unique codes are \n\n");
for(int i=0; i<n; i++) {
for(int j=0; j<length; j++) {
sb.append(str1.charAt(r.nextInt(str1.length())));
}
System.out.println(" " + sb.toString());
sb.delete(0, length);
}
}
}
try this [0-9a-zA-Z]+ for only alpha and num with one char at-least
..
may need modification so test on it

Pattern pattern = Pattern.compile("^[0-9a-zA-Z]+$");
Matcher matcher = pattern.matcher(phoneNumber);
if (matcher.matches()) {
}
Though post is a bit old, I would like to say the following. Issue I had with above solution is that it does not filter out characters like ç, ë, ï, etc. I adapted a function as follows (I only used an 80 varchar string to save memory):
create FUNCTION dbo.udf_Cleanchars (@InputString varchar(80))
RETURNS varchar(80)
AS
BEGIN
declare @return varchar(80) , @length int , @counter int , @cur_char char(1)
SET @return = ''
SET @length = 0
SET @counter = 1
SET @length = LEN(@InputString)
IF @length > 0
BEGIN WHILE @counter <= @length
BEGIN SET @cur_char = SUBSTRING(@InputString, @counter, 1) IF ((ascii(@cur_char) in (32,44,46)) or (ascii(@cur_char) between 48 and 57) or (ascii(@cur_char) between 65 and 90) or (ascii(@cur_char) between 97 and 122))
BEGIN SET @return = @return + @cur_char END
SET @counter = @counter + 1
END END
RETURN @return END
Well I think you just need to add a quantifier to each pattern. Also the carriage-return thing is a little funny:
text.replace(/[^a-z0-9]+|\s+/gmi, " ");
edit The \s
thing matches \r
and \n
too.
[User below code to restrict special character also
$(h.txtAmount).keydown(function (event) {
if (event.shiftKey) {
event.preventDefault();
}
if (event.keyCode == 46 || event.keyCode == 8) {
}
else {
if (event.keyCode < 95) {
if (event.keyCode < 48 || event.keyCode > 57) {
event.preventDefault();
}
}
else {
if (event.keyCode < 96 || event.keyCode > 105) {
event.preventDefault();
}
}
}
});]
It's quite an old question, but in case it could be useful for anyone, starting from a combination of good responses found here, I've ended using this pattern:
pattern="([^\s][A-z0-9À-ž\s]+)"
It will require at least two characters, making sure it does not start with an empty space but allowing spaces between words, and also allowing special characters such as a, ó, ä, ö
.
Try this out..
string[] things = new string[] { "paul", "bob", "lauren", "007", "90", "-10" };
List<int> num = new List<int>();
List<string> str = new List<string>();
for (int i = 0; i < things.Count(); i++)
{
int result;
if (int.TryParse(things[i], out result))
{
num.Add(result);
}
else
{
str.Add(things[i]);
}
}
Now Sort the lists and merge them back...
var strsort = from s in str
orderby s.Length
select s;
var numsort = from n in num
orderby n
select n;
for (int i = 0; i < things.Count(); i++)
{
if(i < numsort.Count())
things[i] = numsort.ElementAt(i).ToString();
else
things[i] = strsort.ElementAt(i - numsort.Count());
}
I jsut tried to make a contribution in this interesting question...
You could just do:
String s = Integer.valueOf("0001007").toString();
Using Apache Commons Lang:
!StringUtils.isAlphanumeric(String)
Alternativly iterate over String's characters and check with:
!Character.isLetterOrDigit(char)
You've still one problem left:
Your example string "abcdefà" is alphanumeric, since à
is a letter. But I think you want it to be considered non-alphanumeric, right?!
So you may want to use regular expression instead:
String s = "abcdefà";
Pattern p = Pattern.compile("[^a-zA-Z0-9]");
boolean hasSpecialChar = p.matcher(s).find();
I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).
If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::
.
Something along these lines:
create view view1
as
select table1.col1,table2.col1,table3.col3
from table1
inner join
table2
inner join
table3
on
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;
Notice the varchar
typecasting on the table1.col4.
Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.
Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).
I use highcharts. They are very interactive (and very fancy I might add). You do have to get a little creative to access data from MySQL database, but if you have a general understanding of JavaScript and PHP, you should have no problems.
You can try this, I know is not the answers you are looking for but the concept is the same.
Where you are setting the styles for all the children and then removing it from the last child.

To Remove element from the list
objectA.removeIf(x -> conditions);
eg:
objectA.removeIf(x -> blockedWorkerIds.contains(x));
List<String> str1 = new ArrayList<String>();
str1.add("A");
str1.add("B");
str1.add("C");
str1.add("D");
List<String> str2 = new ArrayList<String>();
str2.add("D");
str2.add("E");
str1.removeIf(x -> str2.contains(x));
str1.forEach(System.out::println);
OUTPUT: A B C
There is another option not mentioned previously:

function noBack() {
window.history.forward();
}
</script>
<body onpageshow="if (event.persisted) noBack();">

Two ways
1)instantiate the first class
and getter for arrayList
or
2)Make arraylist as static
And finally
MongoDB will find only one matching document which matches the query criteria when you are issuing an update command, whichever document matches first happens to be get updated, even if there are more documents which matches the criteria will get ignored.
so to overcome this we can specify "MULTI" option in your update statement, meaning update all those documnets which matches the query criteria. scan for all the documnets in collection finding those which matches the criteria and update :
db.test.update({"foo":"bar"},{"$set":{"test":"success!"}}, {multi:true} )
If you want to change the title as a response to being tapped you can try this inside the IBAction method of the button in your view controller delegate. This toggles a voice chat on and off. Setting up the voice chat is not covered here!
- (IBAction)startChat:(id)sender {
UIButton *chatButton = (UIButton*)sender;
if (!voiceChat.active) {
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"Voice Chat"
message:@"Voice Chat will become live. Please be careful with feedback if your friend is nearby."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
[voiceChat start];
voiceChat.active = YES;
[chatButton setTitle:@"Stop Chat" forState:UIControlStateNormal];
}
else {
[voiceChat stop];
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"Voice Chat"
message:@"Voice Chat is closed"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
voiceChat.active = NO;
[chatButton setTitle:@"Chat" forState:UIControlStateNormal];
}
}
voiceChat is specific to voice chat of course, but you can use your ow local boolean property to control the switch.
Since Date
implements Comparable<Date>
, it is as easy as:
date1.compareTo(date2);
As the Comparable
contract stipulates, it will return a negative integer/zero/positive integer if date1
is considered less than/the same as/greater than date2
respectively (ie, before/same/after in this case).
Note that Date
has also .after()
and .before()
methods which will return booleans instead.
For me it wasn't an angular problem. Was a field of type DateTime in the DB that has a value of (0000-00-00) and my model cannot bind that property correct so I changed to a valid value like (2019-08-12).
I'm using .net core, OData v4 and MySql (EF pomelo connector)
You can inspect elements of a website in your Android device using Chrome browser.
Open your Chrome browser and go to the website you want to inspect.
Go to the address bar and type "view-source:" before the "HTTP" and reload the page.
The whole elements of the page will be shown.
Should be easier than that. Just use:
<Checkbox IsChecked="{Binding Path=myVar, UpdateSourceTrigger=PropertyChanged}" />
I was facing this problem after adding a jar which is already in the SVN and I added the new Version of it with the same name.

If you want a command-line solution, I suggest to just go with MBO's answer.
If you're a newbie, you might like the graphical approach:
gitk
(from the command line, or right click in file browser if you have that)I hesitate to post this answer, it is actually technically possible but it doesn't work that well in practice. The version numbers of the CLR and the core framework assemblies were not changed in 4.5. You still target v4.0.30319 of the CLR and the framework assembly version numbers are still 4.0.0.0. The only thing that's distinctive about the assembly manifest when you look at it with a disassembler like ildasm.exe is the presence of a [TargetFramework] attribute that says that 4.5 is needed, that would have to be altered. Not actually that easy, it is emitted by the compiler.
The biggest difference is not that visible, Microsoft made a long-overdue change in the executable header of the assemblies. Which specifies what version of Windows the executable is compatible with. XP belongs to a previous generation of Windows, started with Windows 2000. Their major version number is 5. Vista was the start of the current generation, major version number 6.
.NET compilers have always specified the minimum version number to be 4.00, the version of Windows NT and Windows 9x. You can see this by running dumpbin.exe /headers on the assembly. Sample output looks like this:
OPTIONAL HEADER VALUES
10B magic # (PE32)
...
4.00 operating system version
0.00 image version
4.00 subsystem version // <=== here!!
0 Win32 version
...
What's new in .NET 4.5 is that the compilers change that subsystem version to 6.00. A change that was over-due in large part because Windows pays attention to that number, beyond just checking if it is small enough. It also turns on appcompat features since it assumes that the program was written to work on old versions of Windows. These features cause trouble, particularly the way Windows lies about the size of a window in Aero is troublesome. It stops lying about the fat borders of an Aero window when it can see that the program was designed to run on a Windows version that has Aero.
You can alter that version number and set it back to 4.00 by running Editbin.exe on your assemblies with the /subsystem option. This answer shows a sample postbuild event.
That's however about where the good news ends, a significant problem is that .NET 4.5 isn't very compatible with .NET 4.0. By far the biggest hang-up is that classes were moved from one assembly to another. Most notably, that happened for the [Extension] attribute. Previously in System.Core.dll, it got moved to Mscorlib.dll in .NET 4.5. That's a kaboom on XP if you declare your own extension methods, your program says to look in Mscorlib for the attribute, enabled by a [TypeForwardedTo] attribute in the .NET 4.5 version of the System.Core reference assembly. But it isn't there when you run your program on .NET 4.0
And of course there's nothing that helps you stop using classes and methods that are only available on .NET 4.5. When you do, your program will fail with a TypeLoadException or MissingMethodException when run on 4.0
Just target 4.0 and all of these problems disappear. Or break that logjam and stop supporting XP, a business decision that programmers cannot often make but can certainly encourage by pointing out the hassles that it is causing. There is of course a non-zero cost to having to support ancient operating systems, just the testing effort is substantial. A cost that isn't often recognized by management, Windows compatibility is legendary, unless it is pointed out to them. Forward that cost to the client and they tend to make the right decision a lot quicker :) But we can't help you with that.
This works for PL/SQL:
select count(*), id,address from table group by id,address having count(*)<2
If a class type is not defined, you'll get a compiler error if you try to use the class, so in that sense you should have to check.
If you have an instance, and you want to ensure it's not null, simply check for null:
if (value != null)
{
// it's not null.
}
INSERT INTO Table1 SELECT * FROM Table2
Here is a solution using sponge (from the moreutils package):
head -n -1 foo.txt | sponge foo.txt
Summary of solutions:
If you want a fast solution for large files, use the efficient tail or dd approach.
If you want something easy to extend/tweak and portable, use the redirect and move approach.
If you want something easy to extend/tweak, the file is not too large, portability (i.e., depending on moreutils
package) is not an issue, and you are a fan of square pants, consider the sponge approach.
A nice benefit of the sponge approach, compared to "redirect and move" approaches, is that sponge preserves file permissions.
Sponge uses considerably more RAM compared to the "redirect and move" approach. This gains a bit of speed (only about 20%), but if you're interested in speed the "efficient tail" and dd approaches are the way to go.
You could do this but it is hacky
.application-title {

.application-title img {
display:none;
}
Here is a working example:
An IDE which supports Android development is Processing for Android: http://wiki.processing.org/w/Android. Processing is its own language but it's easy to learn. Processing for Android requires the JDK and Android SDK to be installed but runs on its own. It runs on Linux, Mac OSX and Windows (on a side note: one can develop a desktop app in Processing and then compile it to target any of these operating systems). Its development is ongoing but it works. It's especially good for quickly sketching up an idea and running it on your Android phone (even if you plan to develop it further in another IDE).
There is an active support forum here: http://forum.processing.org/android-processing.
You can use a special designated object as the null object in case of references as follows:
class SomeClass
{
public:
int operator==(SomeClass &object)
{
if(this == &object)
{
return true;
}
return false;
}
static SomeClass NullObject;
};
SomeClass SomeClass::NullObject;
void print(SomeClass &val)
{
if(val == SomeClass::NullObject)
{
printf("\nNULL");
}
else
{
printf("\nNOT NULL");
}
}
Each python object has a __dict__
atttribute which is a dictionary containing all other attributes. e.g. when you type self.attr
python is actually doing self.__dict__['attr']
. As you can imagine using a dictionary to store attribute takes some extra space & time for accessing it.
However, when you use __slots__
, any object created for that class won't have a __dict__
attribute. Instead, all attribute access is done directly via pointers.
So if want a C style structure rather than a full fledged class you can use __slots__
for compacting size of the objects & reducing attribute access time. A good example is a Point class containing attributes x & y. If you are going to have a lot of points, you can try using __slots__
in order to conserve some memory.
A complete example in data binding Fragments
FragmentMyProgramsBinding is binding class generated for res/layout/fragment_my_programs
public class MyPrograms extends Fragment {
FragmentMyProgramsBinding fragmentMyProgramsBinding;
public MyPrograms() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
FragmentMyProgramsBinding fragmentMyProgramsBinding = DataBindingUtil.inflate(inflater, R
.layout.fragment_my_programs, container, false);
return fragmentMyProgramsBinding.getRoot();
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}
There are a thousand and one ways to do it. Here's one using dc
(a reverse-polish desk calculator which supports unlimited precision arithmetic):
dc <<<"$num1 $num2 + p"
But if that's too bash-y for you (or portability matters) you could say
echo $num1 $num2 + p | dc
But maybe you're one of those people who thinks RPN is icky and weird; don't worry! bc
is here for you:
bc <<< "$num1 + $num2"
echo $num1 + $num2 | bc
That said, there are some unrelated improvements you could be making to your script:
#!/bin/bash
num=0
metab=0
for ((i=1; i<=2; i++)); do
for j in output-$i-* ; do # 'for' can glob directly, no need to ls
echo "$j"
# 'grep' can read files, no need to use 'cat'
metab=$(grep EndBuffer "$j" | awk '{sum+=$2} END { print sum/120}')
num=$(( $num + $metab ))
done
echo "$num"
done
As described in Bash FAQ 022, Bash does not natively support floating point numbers. If you need to sum floating point numbers the use of an external tool (like bc
or dc
) is required.
In this case the solution would be
num=$(dc <<<"$num $metab + p")
To add accumulate possibly-floating-point numbers into num
.
Think like this:
class Animal { /* Some virtual members */ };
class Dog: public Animal {};
class Cat: public Animal {};
Dog dog;
Cat cat;
Animal& AnimalRef1 = dog; // Notice no cast required. (Dogs and cats are animals).
Animal& AnimalRef2 = cat;
Animal* AnimalPtr1 = &dog;
Animal* AnimlaPtr2 = &cat;
Cat& catRef1 = dynamic_cast<Cat&>(AnimalRef1); // Throws an exception AnimalRef1 is a dog
Cat* catPtr1 = dynamic_cast<Cat*>(AnimalPtr1); // Returns NULL AnimalPtr1 is a dog
Cat& catRef2 = dynamic_cast<Cat&>(AnimalRef2); // Works
Cat* catPtr2 = dynamic_cast<Cat*>(AnimalPtr2); // Works
// This on the other hand makes no sense
// An animal object is not a cat. Therefore it can not be treated like a Cat.
Animal a;
Cat& catRef1 = dynamic_cast<Cat&>(a); // Throws an exception Its not a CAT
Cat* catPtr1 = dynamic_cast<Cat*>(&a); // Returns NULL Its not a CAT.
Now looking back at your first statement:
Animal animal = cat; // This works. But it slices the cat part out and just
// assigns the animal part of the object.
Cat bigCat = animal; // Makes no sense.
// An animal is not a cat!!!!!
Dog bigDog = bigCat; // A cat is not a dog !!!!
You should very rarely ever need to use dynamic cast.
This is why we have virtual methods:
void makeNoise(Animal& animal)
{
animal.DoNoiseMake();
}
Dog dog;
Cat cat;
Duck duck;
Chicken chicken;
makeNoise(dog);
makeNoise(cat);
makeNoise(duck);
makeNoise(chicken);
The only reason I can think of is if you stored your object in a base class container:
std::vector<Animal*> barnYard;
barnYard.push_back(&dog);
barnYard.push_back(&cat);
barnYard.push_back(&duck);
barnYard.push_back(&chicken);
Dog* dog = dynamic_cast<Dog*>(barnYard[1]); // Note: NULL as this was the cat.
But if you need to cast particular objects back to Dogs then there is a fundamental problem in your design. You should be accessing properties via the virtual methods.
barnYard[1]->DoNoiseMake();
I realise this is a moot question to the OP, but I just brewed this, and I'm a tad proud of myself for thinking outside the box.
Download gawk for Windows at http://gnuwin32.sourceforge.net/packages/gawk.htm .... Then it's a one liner, without all that clunky DOS batch syntax, where it takes six FOR loops to split the strings (WTF? That's really really BAD MAD AND SAD! ... IMHO of course)
If you already know C, C++, Perl, or Ruby then picking-up AWK (which inherits from the former two, and contributes significantly to the latter two) is a piece of the proverbial CAKE!!!
The DOS Batch command:
echo %DATE% %TIME% && echo %DATE% %TIME% | gawk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}"
Prints:
Tue 04/09/2012 10:40:38.25
20120904-104038
Now that's not quite the full story... I'm just going to be lazy and hard-code the rest of my log-file-name in the printf statement, because it's simple... But if anybody knows how to set a %NOW% variable to AWK's output (yeilding the guts of a "generic" now function) then I'm all ears.
EDIT:
A quick search on Stack Overflow filled in that last piece of the puzzle, Batch equivalent of Bash backticks.
So, these three lines of DOS batch:
echo %DATE% %TIME% | awk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}" >%temp%\now.txt
set /p now=<%temp%\now.txt
echo %now%
Produce:
20120904-114434
So now I can include a datetime in the name of the log-file produced by my SQL Server installation (2005+) script thus:
sqlcmd -S .\SQLEXPRESS -d MyDb -e -i MyTSqlCommands.sql >MyTSqlCommands.sql.%now%.log
And I'm a happy camper again (except life was still SOOOOO much easier on Unix).
It's possible by accessing the key as index
for example:
Dictionary<string, int> dictionary = new Dictionary<string, int>();
dictionary["test"] = 1;
dictionary["test"] += 1;
Console.WriteLine (dictionary["test"]); // will print 2
In this particular case, you can merge the loops with a modern python (3.0 and probably 2.6, too) by using itertools.product.
I for myself took this as a rule of thumb, if you nest too many loops (as in, more than 2), you are usually able to extract one of the loops into a different method or merge the loops into one, as in this case.
Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)
Do it the other way around:
$a = "1,435";
$b = str_replace( ',', '', $a );
if( is_numeric( $b ) ) {
$a = $b;
}
The easiest would be:
$var = intval(preg_replace('/[^\d.]/', '', $var));
or if you need float:
$var = floatval(preg_replace('/[^\d.]/', '', $var));
I cannot say that it is the "best" library, but I think you can try this: http://algart.net/java/AlgART/ It is an open-source Java library, supporting generalized "smart" arrays and matrices with elements of different types (from 1 bit to 64-bit floating point), including 2D-, 3D- and multidimensional image processing and other algorithms, working with arrays and matrices. Unfortunately right now it consists not enough demo and examples, but, on the other hand, it contains a lot of JavaDocs. It lay in the base of commercial software (SIMAGIS) during several years, but now it is open-source.
If you want to show it in DataGridview , you should change its type , because default is String and since you change it to decimal it considers as Number with floating point
Dim dt As DataTable = New DataTable
dt.Columns.Add("col1", GetType(Decimal))
dt.Rows.Add(1)
dt.Rows.Add(10)
dt.Rows.Add(2)
DataGridView1.DataSource = dt
I found the solution in this topic and I code this:
$cards = DB::select("SELECT
cards.id_card,
cards.hash_card,
cards.`table`,
users.name,
0 as total,
cards.card_status,
cards.created_at as last_update
FROM cards
LEFT JOIN users
ON users.id_user = cards.id_user
WHERE hash_card NOT IN ( SELECT orders.hash_card FROM orders )
UNION
SELECT
cards.id_card,
orders.hash_card,
cards.`table`,
users.name,
sum(orders.quantity*orders.product_price) as total,
cards.card_status,
max(orders.created_at) last_update
FROM menu.orders
LEFT JOIN cards
ON cards.hash_card = orders.hash_card
LEFT JOIN users
ON users.id_user = cards.id_user
GROUP BY hash_card
ORDER BY id_card ASC");
Using plain javascript:
element.parentNode
In jQuery:
element.parent()
In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.
Example:
select * from table order by [some_column]
offset 10 rows
FETCH NEXT 10 rows only
Here is another way to do this - using the API function WideCharToMultiByte:

If size = 0 Then _
Err.Raise 30030, , "WideCharToMultiByte() = 0"
ReDim b(0 To size - 1)

You can use
org.apache.commons.lang3.StringUtils.containsIgnoreCase(CharSequence str,
CharSequence searchStr);
Checks if CharSequence contains a search CharSequence irrespective of case, handling null. Case-insensitivity is defined as by String.equalsIgnoreCase(String).
A null CharSequence will return false.
This one will be better than regex as regex is always expensive in terms of performance.
For official doc, refer to : StringUtils.containsIgnoreCase
Update :
If you are among the ones who
regex/Pattern
based solutions, toLowerCase
, you can implement your own custom containsIgnoreCase
using java.lang.String.regionMatches
public boolean regionMatches(boolean ignoreCase,
int toffset,
String other,
int ooffset,
int len)
ignoreCase
: if true, ignores case when comparing characters.
public static boolean containsIgnoreCase(String str, String searchStr) {
if(str == null || searchStr == null) return false;
final int length = searchStr.length();
if (length == 0)
return true;
for (int i = str.length() - length; i >= 0; i--) {
if (str.regionMatches(true, i, searchStr, 0, length))
return true;
}
return false;
}
Try:
$result = curl_exec($cURL);
$result = json_decode($result,true);
Now you can access MessageID
from $result['MessageID']
.
As for the database, it's simply using a query like so:
INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');
Prepared.

The syntax of this question looks like Robot Framework syntax. In this case, although there is no css selector that you can use for contains, there is a SeleniumLibrary keyword that you can use instead. The Wait Until Element Contains.
Example:
Wait Until Element Contains | ${element} | ${contains}
Wait Until Element Contains | td | male
A common mistake during development of an android app running on a Virtual Device on your dev machine is to forget that the virtual device is not the same host as your dev machine. So if your server is running on your dev machine you cannot use a "http://localhost/..." url as that will look for the server endpoint on the virtual device not your dev machine.
If you are using LESS, you can use Mixins for less code. Here I will add a gradient, border, and border-radius:
.navbar-inner {
#gradient > .vertical(#ffffff, #ECECEC);
border: #E2E2E2;
.border-radius(6px);
}

For a data-only export use COPY
.
You get a file with one table row per line as plain text (not INSERT
commands), it's smaller and faster:
COPY (SELECT * FROM nyummy.cimory WHERE city = 'tokio') TO '/path/to/file.csv';
Import the same to another table of the same structure anywhere with:
COPY other_tbl FROM '/path/to/file.csv';
COPY
writes and read files local to the server, unlike client programs like pg_dump
or psql
which read and write files local to the client. If both run on the same machine, it doesn't matter much, but it does for remote connections.
There is also the \copy
command of psql that:
Performs a frontend (client) copy. This is an operation that runs an SQL
COPY
command, but instead of the server reading or writing the specified file, psql reads or writes the file and routes the data between the server and the local file system. This means that file accessibility and privileges are those of the local user, not the server, and no SQL superuser privileges are required.

If you had caught the error, you would have seen this:
jsonString, err := json.Marshal(datas)
fmt.Println(err)
// [] json: unsupported type: map[int]main.Foo
The thing is you cannot use integers as keys in JSON; it is forbidden. Instead, you can convert these values to strings beforehand, for instance using strconv.Itoa
.

For linux environments, you can use xdg-open
. It is installed by default on most distributions. The benefit over the accepted answer is that it opens the user's preferred browser.
$ xdg-open https://google.com
$ xdg-open steam://run/10
Of course you can wrap this in a system()
call.
I've tried using that 'UniversalBrowswerRead' thing too and it didn't work. You might be able to add an 'allow' header, but I haven't actually tried doing it yet. It's pretty new.

You need to enable the below extension in your php.ini
;extension=php_oci8.dll
;extension=php_oci8_11.g.dll
by removing the ";" so that the results will below:
extension=php_oci8.dll
extension=php_oci8_11.g.dll
Download Oracle Instant Client:- Preferably 32 bit. 32 bit will also work on 64 bit. You can just google: download oracle instant client windows 32 bit. Use version 11 of the client because extension=php_oci8_11.g.dll
won't work with 12. Unzip the package into a location such as C:\Oracle\instantclient_11_2
.
Finally modify the System's PATH
Environment Variable with end location, under system variables not user variables
Then you need to restart the System for PATH
changes to fully propagate.
If you just restart XAMPP/WAMP without restarting the machine the Client's DLL files (i.e. OCL.dll) will not be loaded (nor found)
by PHP's php_oci8_11g.dll
extension.

This works very nicely if you already have the Windows GitHub Client as mentioned by @Tommy in his answer on this related question (How to download source in ZIP format from GitHub?).
I have struggled to successfully pass arguments to the newly opened window.
Here is what I came up with :
function openWindow(path, callback /* , arg1 , arg2, ... */){
var args = Array.prototype.slice.call(arguments, 2); // retrieve the arguments
var w = window.open(path); // open the new window
w.addEventListener('load', afterLoadWindow.bind(w, args), false); // listen to the new window's load event
function afterLoadWindow(/* [arg1,arg2,...], loadEvent */){
callback.apply(this, arguments[0]); // execute the callbacks, passing the initial arguments (arguments[1] contains the load event)
}
}
Example call:
openWindow("/contact",function(firstname, lastname){
this.alert("Hello "+firstname+" "+lastname);
}, "John", "Doe");

Many 3rd party JavaScript libraries allow you to select all elements that have a CSS class of a particular name applied to them. Then you can iterate those elements and dynamically attach the handler.
There is no CSS-specific manner to do this.
In JQuery, you can do:
$(".myCssClass").click(function() { alert("hohoho"); });
A null key can also be helpful when the map stores data for UI selections where the map key represents a bean field.
A corresponding null field value would for example be represented as "(please select)" in the UI selection.
Below is a list of the common key codes for quick reference, taken from Events.h
.
If you need to use these keycodes in an application, you should include the Carbon framework:
Objective-C:
#include <Carbon/Carbon.h>
Swift:
import Carbon.HIToolbox
You can then use the kVK_ANSI_A
constants directly.
The key constants reference physical keys on the keyboard. Their output changes if the typist is using a different keyboard layout. The letters in the constants correspond only to the U.S. QWERTY keyboard layout.
For example, the left ring-finger key on the homerow:
QWERTY keyboard layout
> s > kVK_ANSI_S
> "s"
Dvorak keyboard layout
> o > kVK_ANSI_S
> "o"
Strategies for layout-agnostic conversion of keycode to string, and vice versa, are discussed here:
How to convert ASCII character to CGKeyCode?
From Events.h
:
/*
* Summary:
* Virtual keycodes
*
* Discussion:
* These constants are the virtual keycodes defined originally in
* Inside Mac Volume V, pg. V-191. They identify physical keys on a
* keyboard. Those constants with "ANSI" in the name are labeled
* according to the key position on an ANSI-standard US keyboard.
* For example, kVK_ANSI_A indicates the virtual keycode for the key
* with the letter 'A' in the US keyboard layout. Other keyboard
* layouts may have the 'A' key label on a different physical key;
* in this case, pressing 'A' will generate a different virtual
* keycode.

So for me "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.
If you are importing file1.py
from file2.py
and used this:
if __name__ == '__main__':
# etc
Variables below that in file1.py
cannot be imported to file2.py
because __name__
does not equal __main__
!
If you want to import something from file1.py
to file2.py
, you need to use this in file1.py
:
if __name__ == 'file1':
# etc
In case of doubt, make an assert
statement to determine if __name__=='__main__'
These answers are right, but old and works for Depoloyement Package Model

I just noticed that top is available in adb, so you can do things like
adb shell
top -m 5
to monitor the top five CPU hogging processes.
Or
adb shell top -m 5 -s cpu -n 20 |tee top.log
to record this for one minute and collect the output to a file on your computer.
accuracy_score is a classification metric, you cannot use it for a regression problem.
desired o/p: Enabling feature XYZ......Done
you can use below command

Implement the __eq__
method in your class; something like this:
def __eq__(self, other):
return self.path == other.path and self.title == other.title
Edit: if you want your objects to compare equal if and only if they have equal instance dictionaries:
def __eq__(self, other):
return self.__dict__ == other.__dict__
I found the easiest solution on Windows is to build from source.
You can pretty much follow this guide: http://spark.apache.org/docs/latest/building-spark.html
Download and install Maven, and set MAVEN_OPTS
to the value specified in the guide.
But if you're just playing around with Spark, and don't actually need it to run on Windows for any other reason that your own machine is running Windows, I'd strongly suggest you install Spark on a linux virtual machine. The simplest way to get started probably is to download the ready-made images made by Cloudera or Hortonworks, and either use the bundled version of Spark, or install your own from source or the compiled binaries you can get from the spark website.
First, we need GOPATH
The $GOPATH
is a folder (or set of folders) specified by its environment variable. We must notice that this is not the $GOROOT
directory where Go is installed.
export GOPATH=$HOME/gocode
export PATH=$PATH:$GOPATH/bin
We used ~/gocode
path in our computer to store the source of our application and its dependencies. The GOPATH
directory will also store the binaries of their packages.
Then check Go env
You system must have $GOPATH
and $GOROOT
, below is my Env:
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/elpsstu/gocode"
GORACE=""
GOROOT="/home/pravin/go"
GOTOOLDIR="/home/pravin/go/pkg/tool/linux_amd64"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"
Now, you run download go package:
go get [-d] [-f] [-fix] [-t] [-u] [build flags] [packages]
Get downloads and installs the packages named by the import paths, along with their dependencies. For more details you can look here.
This code does what your need:
<input type="checkbox" id="check" >check it</input>
$("#check").change( function(){
if( $(this).is(':checked') ) {
alert("checked");
}else{
alert("unchecked");
}
});
Also, you can check it on jsfiddle
Improving upon @barry-stae's solution. Stick this snippet in ~/.bashrc
function mdviewer(){
pandoc $* | lynx -stdin
}
Then we can quickly view the file from the command-line. Also works nicely over SSH/Telnet sessions.

If you want to automatically stash your changes and unstash them for every rebase, you can do this:
git config --global rebase.autoStash true
You should take to consideration that $array1 + $array2 != $array2 + $array1
$array1 = array(
'11' => 'x1',
'22' => 'x1'
);
$array2 = array(
'22' => 'x2',
'33' => 'x2'
);
with $array1 + $array2
$array1 + $array2 = array(
'11' => 'x1',
'22' => 'x1',
'33' => 'x2'
);
and with $array2 + $array1
$array2 + $array1 = array(
'11' => 'x1',
'22' => 'x2',
'33' => 'x2'
);
I was totally unable to do this in NP v6.9. I found it easy enough on Msoft Word (2K).
Open the doc, go to edit->replace.
Then in the bottom of the search box, click "more" then find the "Special" button and they have several things for you. For Dos style, I used the "paragraph" one. This is a cr lf pair in windows land.
If you are using TensorFlow 2.0, then some code developed for tf 1.x may not code work. Either you can follow the link : https://www.tensorflow.org/guide/migrate
or you can install a previous version of tf by pip3 install tensorflow==version
You may also try with one list which is a combination of two lists ;)
a = [1,2,3,4]
n = [5,6,7,8]
x = []
for i in a,n:
x.append(i)
print(dict(zip(x[0], x[1])))
While the accepted solution works, it is not complete. By far.
If you want to get all the keys, you need to take into consideration 2 more things:
x86 & x64 applications do not have access to the same registry. Basically x86 cannot normally access x64 registry. And some applications only register to the x64 registry.
and
some applications actually install into the CurrentUser registry instead of the LocalMachine
With that in mind, I managed to get ALL installed applications using the following code, WITHOUT using WMI
Here is the code:
List<string> installs = new List<string>();
List<string> keys = new List<string>() {
@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",
@"SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall"
};
// The RegistryView.Registry64 forces the application to open the registry as x64 even if the application is compiled as x86
FindInstalls(RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64), keys, installs);
FindInstalls(RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64), keys, installs);
installs = installs.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList();
installs.Sort(); // The list of ALL installed applications
private void FindInstalls(RegistryKey regKey, List<string> keys, List<string> installed)
{
foreach (string key in keys)
{
using (RegistryKey rk = regKey.OpenSubKey(key))
{
if (rk == null)
{
continue;
}
foreach (string skName in rk.GetSubKeyNames())
{
using (RegistryKey sk = rk.OpenSubKey(skName))
{
try
{
installed.Add(Convert.ToString(sk.GetValue("DisplayName")));
}
catch (Exception ex)
{ }
}
}
}
}
}
The proper way to do this requires leveraging the SAM registry hive (on Windows 10, this requires NT AUTHORITY\SYSTEM
privileges). The information you require is in the the key: HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\Names
.
Each subkey is the username, and the default value in each subkey is a binary integer. This value (converted to decimal) actually corresponds to the last chunk of the of the SID.
Take "Administrator" for example, by default it is associated with the integer 0x1f4 (or 500).
So, in theory you could take the build a list of SIDS based on the subkey names of the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\ProfileList
key and/or HKEY_USERS
key, parse out the the value after the last hyphen (-), and compare that to the info from the SAM hive.
If you don't have NT AUTHORITY\SYSTEM
privileges, the next best way to approach this may be to follow the other method described in the answers here.
The pickle (and gzip if the file is compressed) module need to be used
NOTE: These are already in the standard Python library. No need to install anything new
I prepared a library based on links posted in this thread. It uses the examples from MSDN and CodeProject. Thanks to James.
I also made modifications advised by Joel Mueller.
Code is here:
https://github.com/dermeister0/LockFreeSessionState
HashTable module:
Install-Package Heavysoft.LockFreeSessionState.HashTable
ScaleOut StateServer module:
Install-Package Heavysoft.LockFreeSessionState.Soss
Custom module:
Install-Package Heavysoft.LockFreeSessionState.Common
If you want to implement support of Memcached or Redis, install this package. Then inherit the LockFreeSessionStateModule class and implement abstract methods.
The code is not tested on production yet. Also need to improve error handling. Exceptions are not caught in current implementation.
Some lock-free session providers using Redis:
You can use the excellent jquery-Json plugin:
http://code.google.com/p/jquery-json/
Makes it easy to convert to and from Json objects.
To the parent div add a height say 50px. In the child span, add the line-height: 50px; Now the text in the span will be vertically center. This worked for me.
To reset the height of the div, just try
$("#someDiv").height('auto');
If you want to echo all days between the start and end date, I came up with this :
$startdatum = $_POST['start']; // starting date
$einddatum = $_POST['eind']; // end date
$now = strtotime($startdatum);
$your_date = strtotime($einddatum);
$datediff = $your_date - $now;
$number = floor($datediff/(60*60*24));
for($i=0;$i <= $number; $i++)
{
echo date('d-m-Y' ,strtotime("+".$i." day"))."<br>";
}
You need astype
:
df['zipcode'] = df.zipcode.astype(str)
#df.zipcode = df.zipcode.astype(str)
For converting to categorical
:
df['zipcode'] = df.zipcode.astype('category')
#df.zipcode = df.zipcode.astype('category')
Another solution is Categorical
:
df['zipcode'] = pd.Categorical(df.zipcode)
Sample with data:
import pandas as pd
df = pd.DataFrame({'zipcode': {17384: 98125, 2680: 98107, 722: 98005, 18754: 98109, 14554: 98155}, 'bathrooms': {17384: 1.5, 2680: 0.75, 722: 3.25, 18754: 1.0, 14554: 2.5}, 'sqft_lot': {17384: 1650, 2680: 3700, 722: 51836, 18754: 2640, 14554: 9603}, 'bedrooms': {17384: 2, 2680: 2, 722: 4, 18754: 2, 14554: 4}, 'sqft_living': {17384: 1430, 2680: 1440, 722: 4670, 18754: 1130, 14554: 3180}, 'floors': {17384: 3.0, 2680: 1.0, 722: 2.0, 18754: 1.0, 14554: 2.0}})

Here is the code for upload to encode and save it to the MySQL
if (!isset($_GET["getfile"])) {
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br>";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"], $_FILES["file"]["name"]);
$bin_string = file_get_contents($_FILES["file"]["name"]);
$hex_string = base64_encode($bin_string);
$mysqli = mysqli_init();

die('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
}
$mysqli->query("INSERT INTO upload(image) VALUES ('" . $hex_string . "')");

}
For showing the image use this
echo "<img src='data:image/jpeg;base64, $image' width=300>";
For me the easiest way to get it to work, is to put the component.requestFocus();
line, after the setVisible(true);
line, at the bottom of your frame or panel constructor.
This probably has something to do with asking for the focus, after all components have been created, because creating a new component, after asking for the focus request, will make your component loose te focus, and make the focus go to your newly created component. At least, that's what I assume.
Yes , It is right that you can not define construct in an Anonymous class but it doesn't mean that anonymous class don't have constructor. Confuse... Actually you can not define construct in an Anonymous class but compiler generates an constructor for it with the same signature as its parent constructor called. If the parent has more than one constructor, the anonymous will have one and only one constructor

Google introduced new API called PercentRelativeLayout
Add compile dependency like
compile 'com.android.support:percent:22.2.0'
in that PercentRelativeLayout is what we can do percentagewise layout
I just did the following (in V 3.5) and it worked like a charm:
<p:column headerText="name" width="20px"/>
This can be done with CSS3:
<input type="text" />
input
{
-moz-border-radius: 15px;
border-radius: 15px;
border:solid 1px black;
padding:5px;
}
However, an alternative would be to put the input
inside a div
with a rounded background, and no border on the input
Use the following query in sql tab:
SHOW CREATE TABLE tablename
To view full query There is this Hyperlink named +Options left above, There select Full Texts
I solved this issue by adding this line
android.overridePathCheck=true
to
gradle.properties
As this message said
This warning can be disabled by using
the command line flag -Dcom.android.build.gradle.overridePathCheck=true,
or adding the line
'com.android.build.gradle.overridePathCheck=true'
to gradle.properties file in the project directory.
You cannot style a variable such as $ip['countryName']
You can only style elements like p,div, etc, or classes and ids.
If you want to style $ip['countryName'] there are several ways.
You can echo it within an element:
echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';
If you want to style both the variables the same style, then set a class like:
echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';
You could also embed the variables within your actual html rather than echoing them out within the code.
$city = $ip['cityName'];
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>

You can always use the plot()
function like so:
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]
plt.figure()
for y in ys:
plt.plot(x, y, 'o')
plt.show()

Add a single line AddKeysToAgent yes
on the top of the .ssh/config file. Ofcourse ssh-agent must be running beforehand. If its not running ( check by prep ssh-agent
) , then simply run it eval $(ssh-agent)
Now, the key is loaded systemwide into the memory and you dont have to type in the passphrase again.

Do you want to return a full row? Does the default row need to have default values or can it be an empty row? Do you want the default row to have the same column structure as the table in question?
Depending on your requirements, you might do something like this:
1) run the query and put results in a temp table (or table variable) 2) check to see if the temp table has results 3) if not, return an empty row by performing a select statement similar to this (in SQL Server):
select '' as columnA, '' as columnB, '' as columnC from #tempTable
Where columnA, columnB and columnC are your actual column names.

mutableDictionary[@"myKey3"] = @3;
The short-hand syntax is called Objective-C Literals
.
Swift
Create:
var dictionary = ["myKey1": 7, "myKey2": 5]
Change:
dictionary["myKey3"] = 3
I had this exact issue, and created a GitHub project for testing and figuring out the correct settings.
It contains a working Dockerfile
with supporting scripts, and a simple docker-compose.yml
for quick testing.
The fix for me was to put "log4j.properties" into the "src" folder. It did not work in my package folder it has to be one up at the very root of source. Adding it to the build path which then moves it to the "Reference Libraries" also did not work.
To repeat: put log4j.properties at the root of your src folder.
my log4j.properties files has the following content which works on the latest version of Spring Tool Suite which is based on Eclipse.
# Configure logging for testing: optionally with log file
#log4j.rootLogger=INFO, stdout
log4j.rootLogger=WARN, stdout, logfile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.File=target/spring.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%
If min value in array, you can try like:
>>> mydict = {"a": -1.5, "b": -1000.44, "c": -3}
>>> min(mydict.values())
-1000.44
A-M's is similar to what the BrowerActivity does. for FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams (768, 512);
I think we can use
FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT,
FrameLayout.LayoutParams.FILL_PARENT)
instead.
Another issue I met is if the video is playing, and user clicks the back button, next time, you go to this activity(singleTop one) and can not play the video. to fix this, I called the
try {
mCustomVideoView.stopPlayback();
mCustomViewCallback.onCustomViewHidden();
} catch(Throwable e) { //ignore }
in the activity's onBackPressed method.
If you add:
jquery.form.min.js
You can simply do this:
<script>
$('#myform').ajaxForm(function(response) {
alert(response);
});
// this will register the AJAX for <form id="myform" action="some_url">
// and when you submit the form using <button type="submit"> or $('myform').submit(), then it will send your request and alert response
</script>
You could use simple $('FORM').serialize() as suggested in post above, but that will not work for FILE INPUTS... ajaxForm() will.
open up console and navigate to bin folder and run
JBOSS_HOME/bin > stanalone.sh
Once it is up and running just copy past your war file in
standalone/deployments folder
Thats probably it for jboss 7.1
I tried the other solutions here, they work but I'm lazy so this is my solution
by right clicking it no longer registers mouse event since a context menu pops up, so you can move the mouse away safely

Selected response is correct, but someone like me, may have issues with async validation with sending request to the server-side - button will be not disabled during given request processing, so button will blink, which looks pretty strange for the users.
To void this, you just need to handle $pending state of the form:
<form name="myForm">
<input name="myText" type="text" ng-model="mytext" required />
<button ng-disabled="myForm.$invalid || myForm.$pending">Save</button>
</form>
I met some problems in Clion and finally, I solved them. Here is some experience.
I think, this is you exactly needed.
Here drawable(xml) file that creates rounded rectangle. round_rect_shape.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#ffffff" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
</shape>
Here layout file: my_layout.xml
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/round_rect_shape"
android:orientation="vertical"
android:padding="5dp" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Something text"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#ff0000" />
<EditText
android:id="@+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<requestFocus />
</EditText>
</LinearLayout>
-> In the above code, LinearLayout having the background(That is the key role to place to create rounded rectangle). So you can place any view like TextView, EditText... in that LinearLayout to see background as round rectangle for all.
chmod u+x program_name
. Then execute it.
If that does not work, copy the program from the USB device to a native volume on the system. Then chmod u+x program_name
on the local copy and execute that.
Unix and Unix-like systems generally will not execute a program unless it is marked with permission to execute. The way you copied the file from one system to another (or mounted an external volume) may have turned off execute permission (as a safety feature). The command chmod u+x name
adds permission for the user that owns the file to execute it.
That command only changes the permissions associated with the file; it does not change the security controls associated with the entire volume. If it is security controls on the volume that are interfering with execution (for example, a noexec
option may be specified for a volume in the Unix fstab
file, which says not to allow execute permission for files on the volume), then you can remount the volume with options to allow execution. However, copying the file to a local volume may be a quicker and easier solution.
The error that you get does not seem to be related to the RequestHeader.
And you seem to be confusing Spring REST services with JAX-RS, your method signature should be something like:
@RequestMapping(produces = "application/json", method = RequestMethod.GET, value = "data")
@ResponseBody
public ResponseEntity<Data> getData(@RequestHeader(value="User-Agent") String userAgent, @RequestParam(value = "ID", defaultValue = "") String id) {
// your code goes here
}
And your REST class should have annotations like:
@Controller
@RequestMapping("/rest/")
Regarding the actual question, another way to get HTTP headers is to insert the HttpServletRequest into your method and then get the desired header from there.
Example:
@RequestMapping(produces = "application/json", method = RequestMethod.GET, value = "data")
@ResponseBody
public ResponseEntity<Data> getData(HttpServletRequest request, @RequestParam(value = "ID", defaultValue = "") String id) {
String userAgent = request.getHeader("user-agent");
}
Don't worry about the injection of the HttpServletRequest because Spring does that magic for you ;)
try overflow hidden on the thing you don't want to scroll while touch event is happening. e.g set overflow hidden on Start and set it back to auto on end.
Did you try it ? I'd be interested to know if this would work.
document.addEventListener('ontouchstart', function(e) {
document.body.style.overflow = "hidden";
}, false);
document.addEventListener('ontouchmove', function(e) {
document.body.style.overflow = "auto";
}, false);
With .Net 4.x you can use Task-based Asynchronous Pattern (TAP) to achieve this:
// .NET 4.x async-await
using UnityEngine;
using System.Threading.Tasks;
public class AsyncAwaitExample : MonoBehaviour
{
private async void Start()
{
Debug.Log("Wait.");
await WaitOneSecondAsync();
DoMoreStuff(); // Will not execute until WaitOneSecond has completed
}
private async Task WaitOneSecondAsync()
{
await Task.Delay(TimeSpan.FromSeconds(1));
Debug.Log("Finished waiting.");
}
}
this is a feature to use .Net 4.x with Unity please see this link for description about it
and this link for sample project and compare it with coroutine
But becareful as documentation says that This is not fully replacement with coroutine
Building upon Vadian's answer, I wrote an extension that takes a Double
(of which TimeInterval
is a type alias) and spits out a string formatted as time.
extension Double {
func asString(style: DateComponentsFormatter.UnitsStyle) -> String {
let formatter = DateComponentsFormatter()
formatter.allowedUnits = [.hour, .minute, .second, .nanosecond]
formatter.unitsStyle = style
guard let formattedString = formatter.string(from: self) else { return "" }
return formattedString
}
}
Here are what the various DateComponentsFormatter.UnitsStyle
options look like:
10000.asString(style: .positional) // 2:46:40
10000.asString(style: .abbreviated) // 2h 46m 40s
10000.asString(style: .short) // 2 hr, 46 min, 40 sec
10000.asString(style: .full) // 2 hours, 46 minutes, 40 seconds
10000.asString(style: .spellOut) // two hours, forty-six minutes, forty seconds
10000.asString(style: .brief) // 2hr 46min 40sec
This works for me
dataGridView1.Rows[rowIndex].Cells[columnIndex].Style.BackColor = Color.Red;
Below code can work for Single line and Multi-line textview
isMultiLine = If true then Textview showing with Multi-line otherwise single line
if (isMultiLine) {
textView.setElegantTextHeight(true);
textView.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);
textView.setSingleLine(false);
} else {
textView.setSingleLine(true);
textView.setEllipsize(TextUtils.TruncateAt.END);
}
new Double(object.toString());
But it seems weird to me that you're going from an Object to a Double. You should have a better idea what class of object you're starting with before attempting a conversion. You might have a bit of a code quality problem there.
Note that this is a conversion, not casting.
In addition to the Oracle instant client, you may also need to install the Oracle ODAC components and put the path to them into your system path. cx_Oracle seems to need access to the oci.dll file that is installed with them.
Also check that you get the correct version (32bit or 64bit) of them that matches your: python, cx_Oracle, and instant client versions.
As for me to make the code readable in future the most useful aplyable case of enumeration is represented in next snippet:
public enum Items {
MESSAGES, CHATS, CITY_ONLINE, FRIENDS, PROFILE, SETTINGS, PEOPLE_SEARCH, CREATE_CHAT
}
@Override
public boolean onCreateOptionsMenu(Menu menuPrm) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menuPrm);
View itemChooserLcl;
for (int i = 0; i < menuPrm.size(); i++) {
MenuItem itemLcl = menuPrm.getItem(i);
itemChooserLcl = itemLcl.getActionView();
if (itemChooserLcl != null) {
//here Im marking each View' tag by enume values:
itemChooserLcl.setTag(Items.values()[i]);
itemChooserLcl.setOnClickListener(drawerMenuListener);
}
}
return true;
}
private View.OnClickListener drawerMenuListener=new View.OnClickListener() {
@Override
public void onClick(View v) {
Items tagLcl= (Items) v.getTag();
switch (tagLcl){
case MESSAGES: ;
break;
case CHATS : ;
break;
case CITY_ONLINE : ;
break;
case FRIENDS : ;
break;
case PROFILE: ;
break;
case SETTINGS: ;
break;
case PEOPLE_SEARCH: ;
break;
case CREATE_CHAT: ;
break;
}
}
};
Another option I have working, in a linux server with Postfix:
First, configure CI email to use your server's email system: eg, in email.php
, for example
# alias to postfix in a typical Postfix server
$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
Then configure your postfix to relay the mail to google (perhaps depending on the sender address). You'll probably need to put you user-password settings in /etc/postfix/sasl_passwd
(docs)
This is much simpler (and less fragmente) if you have a linux box, already configured to send some/all of its outgoing emails to Google.
$array = array('foo' => 'bar', 33 => 'bin', 'lorem' => 'ipsum');
$array = array_values($array);
echo $array[0]; //bar
echo $array[1]; //bin
echo $array[2]; //ipsum
Based on Ali's and Champitoad's answer:
If you want to try different palettes for the same, you can do this in a few lines:
cmap=plt.cm.get_cmap(plt.cm.viridis,143)
^143 being the number of colours you're sampling
I picked 143 because the entire range of colours on the colormap comes into play here. What you can do is sample the nth colour every iteration to get the colormap effect.
n=20
for i,(x,y) in enumerate(points):
plt.scatter(x,y,c=cmap(n*i))
You can use selectedIndex
to retrieve the current selected option
:
el = document.getElementById('elemId')
selectedText = el.options[el.selectedIndex].text
function alertWithoutNotice(message){
setTimeout(function(){
alert(message);
}, 1000);
}
One thing you can do is this:
$(this)[0].value = "Something";
This allows jQuery to return the javascript object for that element, and you can bypass jQuery Functions.
If I understand correctly, what you want to do is to have a clean environment to be set up for DB involving integration tests.
My approach here would be to drop the whole schema and recreate it later.
As an aside, when trying to diagnose a similar bug I realised that jquery's ajax error callback returns a status of "timeout" if it failed due to a timeout.
Here's an example:
$.ajax({
url: "/ajax_json_echo/",
timeout: 500,
error: function(jqXHR, textStatus, errorThrown) {
alert(textStatus); // this will be "timeout"
}
});
df.index.name
should do the trick.
Python has a dir
function that let's you query object attributes. dir(df.index)
was helpful here.
In your Jenkins job configuration, tick the box named "This build is parameterized
", click the "Add Parameter
" button and select the "String Parameter
" drop down value.
Now define your parameter - example:
Now you can use your parameter in your job / build pipeline, example:
Next to trigger the build with own/custom parameter, invoke the following URL (using either POST or GET):
http://JENKINS_SERVER_ADDRESS/job/YOUR_JOB_NAME/buildWithParameters?myparam=myparam_value
Option 1: go to redis installation directory and navigate to src
, in my case :
/opt/redis3/src/redis-cli -p 6379 shutdown
where 6379 is the default port.
Option 2: find redis process and kill
ps aux | grep redis-server
t6b3fg 22292 0.0 0.0 106360 1588 pts/0 S+ 01:19 0:00 /bin/sh /sbin/service redis start
t6b3fg 22299 0.0 0.0 11340 1200 pts/0 S+ 01:19 0:00 /bin/sh /etc/init.d/redis start
And Then initiate kill:
kill -9 22292
kill -9 22299
I'm using Centos 6.7 , x86_64
hope it helps
SELECT name
FROM orders,company
WHERE orderID = 1
AND companyID IN (attachedCompanyIDs)
attachedCompanyIDs
is a scalar value which is cast into INT
(type of companyID
).
The cast only returns numbers up to the first non-digit (a comma in your case).
Thus,
companyID IN ('1,2,3') = companyID IN (CAST('1,2,3' AS INT)) = companyID IN (1)
In PostgreSQL
, you could cast the string into array (or store it as an array in the first place):
SELECT name
FROM orders
JOIN company
ON companyID = ANY (('{' | attachedCompanyIDs | '}')::INT[])
WHERE orderID = 1
and this would even use an index on companyID
.
Unfortunately, this does not work in MySQL
since the latter does not support arrays.
You may find this article interesting (see #2
):
Update:
If there is some reasonable limit on the number of values in the comma separated lists (say, no more than 5
), so you can try to use this query:
SELECT name
FROM orders
CROSS JOIN
(
SELECT 1 AS pos
UNION ALL
SELECT 2 AS pos
UNION ALL
SELECT 3 AS pos
UNION ALL
SELECT 4 AS pos
UNION ALL
SELECT 5 AS pos
) q
JOIN company
ON companyID = CAST(NULLIF(SUBSTRING_INDEX(attachedCompanyIDs, ',', -pos), SUBSTRING_INDEX(attachedCompanyIDs, ',', 1 - pos)) AS UNSIGNED)
You can either use:
<button onclick="window.history.back()">Back</button>
or..
<button onclick="window.history.go(-1)">Back</button>
The difference, of course, is back()
only goes back 1 page but go()
goes back/forward the number of pages you pass as a parameter, relative to your current page.
Try this... Worked for me and printed 10/22/2013 01:37:56 AM
Ofcourse this is your code only with little modifications.
final SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("UTC")); // This line converts the given date into UTC time zone
final java.util.Date dateObj = sdf.parse("2013-10-22T01:37:56");
aRevisedDate = new SimpleDateFormat("MM/dd/yyyy KK:mm:ss a").format(dateObj);
System.out.println(aRevisedDate);
'JavaType' works !!
I was trying to unmarshall (deserialize) a List in json String to ArrayList java Objects and was struggling to find a solution since days.
Below is the code that finally gave me solution.
Code:
JsonMarshallerUnmarshaller<T> {
T targetClass;
public ArrayList<T> unmarshal(String jsonString) {
ObjectMapper mapper = new ObjectMapper();
AnnotationIntrospector introspector = new JacksonAnnotationIntrospector();
mapper.getDeserializationConfig()
.withAnnotationIntrospector(introspector);
mapper.getSerializationConfig()
.withAnnotationIntrospector(introspector);
JavaType type = mapper.getTypeFactory().
constructCollectionType(
ArrayList.class,
targetclass.getClass());
try {
Class c1 = this.targetclass.getClass();
Class c2 = this.targetclass1.getClass();
ArrayList<T> temp = (ArrayList<T>)
mapper.readValue(jsonString, type);
return temp ;
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null ;
}
}
On one project where we had 4 environments (development, test, staging and production) we developed a system where the application selected the appropriate configuration based on the machine name it was deployed to.
This worked for us because:
It worked well for us in this instance, but probably wouldn't work everywhere.
With ES2015/ES6 String.prototype.normalize(),
const str = "Crème Brulée"
str.normalize("NFD").replace(/[\u0300-\u036f]/g, "")
> "Creme Brulee"
Two things are happening here:
normalize()
ing to NFD
Unicode normal form decomposes combined graphemes into the combination of simple ones. The è
of Crème
ends up expressed as e
+ `
.See comment for performance testing.
Alternatively, if you just want sorting
Intl.Collator has sufficient support ~95% right now, a polyfill is also available here but I haven't tested it.
const c = new Intl.Collator();
["creme brulee", "crème brulée", "crame brulai", "crome brouillé",
"creme brulay", "creme brulfé", "creme bruléa"].sort(c.compare)
["crame brulai", "creme brulay", "creme bruléa", "creme brulee",
"crème brulée", "creme brulfé", "crome brouillé"]
["creme brulee", "crème brulée", "crame brulai", "crome brouillé"].sort((a,b) => a>b)
["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]
'Jigloo' is a very cool GUI designer. It is not free for commercial use however. It auto-generates code and allows for custom editing of the code it creates.
Ranges from -9,223,372,036,854,775,808 to +9,223,372,036,854,775,807.
It will start from -9,223,372,036,854,775,808
Long.MIN_VALUE.
It depends on the package. If the Makefile is generated by GNU autotools (./configure
) you can usually set the target location like so:
./configure --prefix=/somewhere/else/than/usr/local
If the Makefile is not generated by autotools, but distributed along with the software, simply open it up in an editor and change it. The install target directory is probably defined in a variable somewhere.
To avoid confusion, paraphrasing both question and answer. I am assuming that user who posted this question wanted to save dictionary type object in JSON file format but when the user used json.dump
, this method dumped all its content in one line. Instead, he wanted to record each dictionary entry on a new line. To achieve this use:
with g as outfile:
json.dump(hostDict, outfile,indent=2)
Using indent = 2
helped me to dump each dictionary entry on a new line. Thank you @agf. Rewriting this answer to avoid confusion.
I' ve got the same problem. My solution is this :
If you using LinQ2SQL in your project, Open your dbml file in Visual Studio and change Serialization Mode to "Unidirectional" on
Update
The answer was added was in 2015 and the following methods are deprecated now
$this->router->fetch_class(); in favour of $this->router->class;
$this->router->fetch_method(); in favour of $this->router->method;
Hi you should use the following approach
$this->router->fetch_class(); // class = controller
$this->router->fetch_method(); // action
for this purpose but for using this you need to extend your hook from the CI_Controller
and it works like a charm, you should not use uri segments
What all of these answers do not highlight is that when comparing a value to $null, you have to put $null on the left-hand side, otherwise you may get into trouble when comparing with a collection-type value. See: https://github.com/nightroman/PowerShellTraps/blob/master/Basic/Comparison-operators-with-collections/looks-like-object-is-null.ps1
$value = @(1, $null, 2, $null)
if ($value -eq $null) {
Write-Host "$value is $null"
}
The above block is (unfortunately) executed. What's even more interesting is that in Powershell a $value can be both $null and not $null:
$value = @(1, $null, 2, $null)
if (($value -eq $null) -and ($value -ne $null)) {
Write-Host "$value is both $null and not $null"
}
So it is important to put $null on the left-hand side to make these comparisons work with collections:
$value = @(1, $null, 2, $null)
if (($null -eq $value) -and ($null -ne $value)) {
Write-Host "$value is both $null and not $null"
}
I guess this shows yet again the power of Powershell !
Here's a possible solution that will color the entire row for your table.
CSS
tr.highlighted td {
background: red;
}
jQuery
$('#data tr').click(function(e) {
$('#data tr').removeClass('highlighted');
$(this).toggleClass('highlighted');
});
I just wrote a crazy set of CSS for this that seems to work perfectly:
table {
border-collapse: separate;
border-spacing: 0;
width: 100%;
}
table td,
table th {
border-right: 1px solid #CCC;
border-top: 1px solid #CCC;
padding: 3px 5px;
vertical-align: top;
}
table td:first-child,
table th:first-child {
border-left: 1px solid #CCC;
}
table tr:last-child td,
table tr:last-child th {
border-bottom: 1px solid #CCC;
}
table thead + tbody tr:first-child td {
border-top: 0;
}
table thead td,
table th {
background: #EDEDED;
}
/* complicated rounded table corners! */
table thead:first-child tr:last-child td:first-child {
border-bottom-left-radius: 0;
}
table thead:first-child tr:last-child td:last-child {
border-bottom-right-radius: 0;
}
table thead + tbody tr:first-child td:first-child {
border-top-left-radius: 0;
}
table thead + tbody tr:first-child td:last-child {
border-top-right-radius: 0;
}
table tr:first-child td:first-child,
table thead tr:first-child td:first-child {
border-top-left-radius: 5px;
}
table tr:first-child td:last-child,
table thead tr:first-child td:last-child {
border-top-right-radius: 5px;
}
table tr:last-child td:first-child,
table thead:last-child tr:last-child td:first-child {
border-bottom-left-radius: 5px;
}
table tr:last-child td:last-child,
table thead:last-child tr:last-child td:last-child {

/* end complicated rounded table corners !*/
Let's just say you have 3 buttons:
<input type="button" disabled="disabled" value="hello world">
<input type="button" disabled value="hello world">
<input type="button" value="hello world">
To style the disabled button you can use the following css:
input[type="button"]:disabled{
color:#000;
}
This will only affect the button which is disabled.
To stop the color changing when hovering you can use this too:
input[type="button"]:disabled:hover{
color:#000;
}
You can also avoid this by using a css-reset.
As far as I know, there is only one small difference is when you are trying to insert value which is out of range.
In examples I'll use
401421228216
, which is101110101110110100100011101100010111000
(length 39 characters)
INT(20)
for system this means allocate in memory minimum 20 bits. But if you'll insert value that bigger than 2^20
, it will be stored successfully, only if it's less then INT(32) -> 2147483647
(or 2 * INT(32) -> 4294967295
for UNSIGNED
)Example:
mysql> describe `test`;
+-------+------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+------------------+------+-----+---------+-------+
| id | int(20) unsigned | YES | | NULL | |
+-------+------------------+------+-----+---------+-------+
1 row in set (0,00 sec)
mysql> INSERT INTO `test` (`id`) VALUES (401421228216);
ERROR 1264 (22003): Out of range value for column 'id' at row 1
mysql> SET sql_mode = '';
Query OK, 0 rows affected, 1 warning (0,00 sec)
mysql> INSERT INTO `test` (`id`) VALUES (401421228216);
Query OK, 1 row affected, 1 warning (0,06 sec)
mysql> SELECT * FROM `test`;
+------------+
| id |
+------------+
| 4294967295 |
+------------+
1 row in set (0,00 sec)
BIGINT(20)
for system this means allocate in memory minimum 20 bits. But if you'll insert value that bigger than 2^20
, it will be stored successfully, if it's less then BIGINT(64) -> 9223372036854775807
(or 2 * BIGINT(64) -> 18446744073709551615
for UNSIGNED
)Example:

Try this more succinct code:
Sub LoopOverEachColumn()
Dim WS As Worksheet
For Each WS In ThisWorkbook.Worksheets
ResizeColumns WS
Next WS
End Sub
Private Sub ResizeColumns(WS As Worksheet)
Dim StrSize As String
Dim ColIter As Long
StrSize = "20.14;9.71;35.86;30.57;23.57;21.43;18.43;23.86;27.43;36.71;30.29;31.14;31;41.14;33.86"
For ColIter = 1 To 15
WS.Columns(ColIter).ColumnWidth = Split(StrSize, ";")(ColIter - 1)
Next ColIter
End Sub
If you want additional columns, just change 1 to 15
to 1 to X
where X
is the column index of the column you want, and append the column size you want to StrSize
.
For example, if you want P:P
to have a width of 25
, just add ;25
to StrSize
and change ColIter...
to ColIter = 1 to 16
.
Hope this helps.
as aside tip make sure your button is not subclass of any custom class in story board , in such a case your code best place should be in custom class it self cause code works only out of the custom class if your button is subclass of the default UIButton class and outlet of it , hope this may help anyone wonders why corner radios doesn't apply on my button from code .
To do this in Python (i.e. not wrapping scp through subprocess.Popen or similar) with the Paramiko library, you would do something like this:
import os
import paramiko
ssh = paramiko.SSHClient()
ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts")))
ssh.connect(server, username=username, password=password)
sftp = ssh.open_sftp()
sftp.put(localpath, remotepath)
sftp.close()
ssh.close()
(You would probably want to deal with unknown hosts, errors, creating any directories necessary, and so on).
If you don't want to use numpy or a collections module you can use a dictionary:
d = dict()
a = [0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1]
for item in a:
try:
d[item]+=1
except KeyError:
d[item]=1
result:
>>>d
{0: 8, 1: 4}
Of course you can also use an if/else statement. I think the Counter function does almost the same thing but this is more transparant.
Since version 5.7 TCPDF includes support for CSS borders. Margins, padding and float are not yet supported. Check the TCPDF website at http://www.tcpdf.org and consult the official forum for further information.
Canvas
text support is actually pretty good - you can control font
, size
, color
, horizontal alignment
, vertical alignment
, and you can also get text metrics to get the text width in pixels. In addition, you can also use canvas transforms
to rotate
, stretch
and even invert
text.
There's the NUMBERFORMATTER jQuery plugin, details below:
https://code.google.com/p/jquery-numberformatter/
From the above link:
This plugin is a NumberFormatter plugin. Number formatting is likely familiar to anyone who's worked with server-side code like Java or PHP and who has worked with internationalization.
EDIT: Replaced the link with a more direct one.
Use:
jQuery(document).ready(function($){
// code where you can use $ thanks to the parameter
});
Or its shorter version:
jQuery(function($){
// code where you can use $ thanks to the parameter
});
You could add in your code a call system with the new definition:
sprintf(newdef,"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:%s:%s",ld1,ld2);
system(newdef);
But, I don't know it that is the rigth solution but it works.
Regards
You can use isset()
.
<form method="post">
<input type="submit" name="test" id="test" value="RUN" />
</form>
<?php
function testfun()
{
echo "Your test function on button click is working";
}
if(isset($_POST('submit')))
{
testfun();
}
?>
Look at these to build a solution more or less from scratch:
You always have the option of calling external tools from Java using the exec()
and similar methods. For instance, you could use wget
, or cURL
.
Then if you want to go into more fully-fledged stuff, thankfully the need for automated web-testing as given us very practical tools for this. Look at:
Some other libs are purposefully written with web-scraping in mind:
Java is a language, but also a platform, with many other languages running on it. Some of which integrate great syntactic sugar or libraries to easily build scrapers.
Check out:
If you know of a great library for Ruby (JRuby, with an article on scraping with JRuby and HtmlUnit) or Python (Jython) or you prefer these languages, then give their JVM ports a chance.
Some other similar questions:
There is an overload of Split that takes strings.
"THExxQUICKxxBROWNxxFOX".Split(new [] { "xx" }, StringSplitOptions.None);
You can use either of these StringSplitOptions
So if the string is "THExxQUICKxxxxBROWNxxFOX", StringSplitOptions.None
will return an empty entry in the array for the "xxxx" part while StringSplitOptions.RemoveEmptyEntries
will not.
It's also possible to specify the ForeignKey()
attribute on the navigation property:
[ForeignKey("HomeTeamID")]
public virtual Team HomeTeam { get; set; }
[ForeignKey("GuestTeamID")]
public virtual Team GuestTeam { get; set; }
That way you don't need to add any code to the OnModelCreate
method
Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)
Once you've generated your JSON, you can use something like the code below to POST it
StringRequestEntity requestEntity = new StringRequestEntity(
JSON_STRING,
"application/json",
"UTF-8");
PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);
int statusCode = httpClient.executeMethod(postMethod);
Edit
Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:
StringEntity requestEntity = new StringEntity(
JSON_STRING,
ContentType.APPLICATION_JSON);
HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);
HttpResponse rawResponse = httpclient.execute(postMethod);
Found this useful - ensures the compiled Assembly references everything you currently have referenced, since there's a good chance you wanted the C# you're compiling to use some classes etc in the code that's emitting this:
(string code
is the dynamic C# being compiled)
var refs = AppDomain.CurrentDomain.GetAssemblies();
var refFiles = refs.Where(a => !a.IsDynamic).Select(a => a.Location).ToArray();
var cSharp = (new Microsoft.CSharp.CSharpCodeProvider()).CreateCompiler();
var compileParams = new System.CodeDom.Compiler.CompilerParameters(refFiles);
compileParams.GenerateInMemory = true;
compileParams.GenerateExecutable = false;
var compilerResult = cSharp.CompileAssemblyFromSource(compileParams, code);
var asm = compilerResult.CompiledAssembly;
In my case I was emitting a class, whose name was stored in a string, className
, which had a single public static method named Get()
, that returned with type StoryDataIds
. Here's what calling that method looks like:
var tempType = asm.GetType(className);
var ids = (StoryDataIds)tempType.GetMethod("Get").Invoke(null, null);
Warning: Compilation can be surprisingly, extremely slow. A small, relatively simple 10-line chunk of code compiles at normal priority in 2-10 seconds on our relatively fast server. You should never tie calls to CompileAssemblyFromSource()
to anything with normal performance expectations, like a web request. Instead, proactively compile code you need on a low-priority thread and have a way of dealing with code that requires that code to be ready, until it's had a chance to finish compiling. For example you could use it in a batch job process.
Maybe it's too late for an answer to this question but i think i have found a fix for it, what i noticed is within the info.plist file > JVMoption (Mac) with in the application package there is two version of java i.e it was showing "1.6*,1.7+" so i just changed it to "1.8*" which is my current java version and now its working for me
Your app is being detected as some harmful program. Turn off "Verify apps over USB" option. It's in the same view as "USB debugging".
Take a look at Directory.GetFiles Method (String, String) (MSDN).
This method returns all the files as an array of filenames.
Just to augment the accepted answer with a brief newbie-friendly short answer, you probably don't need exec
.
If you're still here, the following discussion should hopefully reveal why. When you run, say,
sh -c 'command'
you run a sh
instance, then start command
as a child of that sh
instance. When command
finishes, the sh
instance also finishes.
sh -c 'exec command'
runs a sh
instance, then replaces that sh
instance with the command
binary, and runs that instead.
Of course, both of these are useless in this limited context; you simply want
command
There are some fringe situations where you want the shell to read its configuration file or somehow otherwise set up the environment as a preparation for running command
. This is pretty much the sole situation where exec command
is useful.
#!/bin/sh
ENVIRONMENT=$(some complex task)
exec command
This does some stuff to prepare the environment so that it contains what is needed. Once that's done, the sh
instance is no longer necessary, and so it's a (minor) optimization to simply replace the sh
instance with the command
process, rather than have sh
run it as a child process and wait for it, then exit as soon as it finishes.
Similarly, if you want to free up as much resources as possible for a heavyish command at the end of a shell script, you might want to exec
that command as an optimization.
If something forces you to run sh
but you really wanted to run something else, exec something else
is of course a workaround to replace the undesired sh
instance (like for example if you really wanted to run your own spiffy gosh
instead of sh
but yours isn't listed in /etc/shells
so you can't specify it as your login shell).
The second use of exec
to manipulate file descriptors is a separate topic. The accepted answer covers that nicely; to keep this self-contained, I'll just defer to the manual for anything where exec
is followed by a redirect instead of a command name.
If its only the cluttering what gives the problem in the constructor
why not implement a initialize
method that intializes
the variables. This is a normal thing to do when the constructor gets to full with unnecessary stuff. Even in typed program languages like C#
its normal convention to add an Initialize
method to handle that.
The easiest solution I found for this so far is the Non-Sucking Service Manager
Usage would be
nssm install <servicename> "C:\Program Files\Java\jre7\java.exe" "-jar <path-to-jar-file>"
I'd like to thank the answer by Apostolos for bringing this to my attention. Here's a much more detailed example for Python 3 in the year 2019, with a clearer description and example code.
destroy()
(or not having a custom window closing handler at all) will destroy the window and all of its running callbacks instantly when the user closes it.This can be bad for you, depending on your current Tkinter activity, and especially when using tkinter.after
(periodic callbacks). You might be using a callback which processes some data and writes to disk... in that case, you obviously want the data writing to finish without being abruptly killed.
The best solution for that is to use a flag. So when the user requests window closing, you mark that as a flag, and then react to it.
(Note: I normally design GUIs as nicely encapsulated classes and separate worker threads, and I definitely don't use "global" (I use class instance variables instead), but this is meant to be a simple, stripped-down example to demonstrate how Tk abruptly kills your periodic callbacks when the user closes the window...)
from tkinter import *
import time
# Try setting this to False and look at the printed numbers (1 to 10)
# during the work-loop, if you close the window while the periodic_call
# worker is busy working (printing). It will abruptly end the numbers,
# and kill the periodic callback! That's why you should design most
# applications with a safe closing callback as described in this demo.
safe_closing = True
# ---------
busy_processing = False
close_requested = False
def close_window():
global close_requested
close_requested = True
print("User requested close at:", time.time(), "Was busy processing:", busy_processing)
root = Tk()
if safe_closing:
root.protocol("WM_DELETE_WINDOW", close_window)
lbl = Label(root)
lbl.pack()
def periodic_call():
global busy_processing
if not close_requested:
busy_processing = True
for i in range(10):
print((i+1), "of 10")
time.sleep(0.2)
lbl["text"] = str(time.time()) # Will error if force-closed.
root.update() # Force redrawing since we change label multiple times in a row.
busy_processing = False
root.after(500, periodic_call)
else:
print("Destroying GUI at:", time.time())
try: # "destroy()" can throw, so you should wrap it like this.
root.destroy()
except:
# NOTE: In most code, you'll wanna force a close here via
# "exit" if the window failed to destroy. Just ensure that
# you have no code after your `mainloop()` call (at the
# bottom of this file), since the exit call will cause the
# process to terminate immediately without running any more
# code. Of course, you should NEVER have code after your
# `mainloop()` call in well-designed code anyway...
# exit(0)
pass
root.after_idle(periodic_call)
root.mainloop()
This code will show you that the WM_DELETE_WINDOW
handler runs even while our custom periodic_call()
is busy in the middle of work/loops!
We use some pretty exaggerated .after()
values: 500 milliseconds. This is just meant to make it very easy for you to see the difference between closing while the periodic call is busy, or not... If you close while the numbers are updating, you will see that the WM_DELETE_WINDOW
happened while your periodic call "was busy processing: True". If you close while the numbers are paused (meaning that the periodic callback isn't processing at that moment), you see that the close happened while it's "not busy".
In real-world usage, your .after()
would use something like 30-100 milliseconds, to have a responsive GUI. This is just a demonstration to help you understand how to protect yourself against Tk's default "instantly interrupt all work when closing" behavior.
In summary: Make the WM_DELETE_WINDOW
handler set a flag, and then check that flag periodically and manually .destroy()
the window when it's safe (when your app is done with all work).
PS: You can also use WM_DELETE_WINDOW
to ask the user if they REALLY want to close the window; and if they answer no, you don't set the flag. It's very simple. You just show a messagebox in your WM_DELETE_WINDOW
and set the flag based on the user's answer.
The main difference is that the output of pip freeze
can be dumped into a requirements.txt file and used later to re-construct the "frozen" environment.
In other words you can run:
pip freeze > frozen-requirements.txt
on one machine and then later on a different machine or on a clean environment you can do:
pip install -r frozen-requirements.txt
and you'll get the an identical environment with the exact same dependencies installed as you had in the original environment where you generated the frozen-requirements.txt.
The only way to determine this is to try it. FWIW I have seen some really good improvements using Apple's LLVM gcc 4.2 compared to the regular gcc 4.2 (for x86-64 code with quite a lot of SSE), but YMMV for different code bases. Assuming you're working with x86/x86-64 and that you really do care about the last few percent then you ought to try Intel's ICC too, as this can often beat gcc - you can get a 30 day evaluation license from intel.com and try it.
https://docs.angularjs.org/guide/$location#html-link-rewriting
In cases like the following, links are not rewritten; instead, the browser will perform a full page reload to the original link.
Links that contain target element Example:
<a href="/ext/link?a=b" target="_self">link</a>
Absolute links that go to a different domain Example:
<a href="http://angularjs.org/">link</a>
Links starting with '/' that lead to a different base path when base is defined Example:
<a href="/not-my-base/link">link</a>
So in your case, you should add a target attribute like so...
<a target="_self" href="example.com/uploads/asd4a4d5a.pdf" download="foo.pdf">
I've found out a nice workaround to IP blocking when scraping sites. It lets you run a Scraper indefinitely by running it from Google App Engine and redeploying it automatically when you get a 429.

Open Terminal
cd to/the/program/location
ruby program.rb
or add #!/usr/bin/env ruby
in the first of your program (script tell that this is executed using Ruby Interpreter)
Open Terminal
cd to/the/program/location
chmod 777 program.rb
./program.rb
you can use
df.describe()
you will get basic statistics of the dataframe and to get mean of specific column you can use
df["columnname"].mean()
It may be "better" to not use attach
at all. On the plus side, you can save some typing if you use attach
. Let's say your dataset is called mydata
and you have variables called v1
, v2
, and v3
. If you don't attach mydata
, then you will type mean(mydata$v1)
to get the mean of v1
. If you do attach mydata
, then you will type mean(v1)
to get the mean of v1
. But, if you don't detach the mydata
dataset (every time), you'll get the message about the objects being masked going forward.
detach
every time.Don't use attach
. Instead, include the dataset name every time you refer to a variable. The form is mydata$v1
(name of data set, dollar sign, name of variable).
As for me, I used solution 1 a lot in the past, but I've moved to solution 2. It's a bit more typing in the beginning, but if you are going to use the code multiple times, it just seems cleaner.
Even though this is a really old question, this may work.

You cannot use ++
on something which is not a variable, this would be the closest you can get:
$('#counter').html(function(i, val) { return +val+1 });
jQuery's html()
method can get and set the HTML value of an element. If passed a function it can update the HTML based upon the existing value. So in the context of your code:
$("#update").click(function() {
$('#counter').html(function(i, val) { return +val+1 });
}
DEMO: http://jsfiddle.net/marcuswhybrow/zRX2D/2/
When it comes to synchronising your counter on the page, with the counter value in your database, never trust the client! You send either an increment or decrement signal to you server side script, rather than a continuous value such as 10, or 23.
However you could send an AJAX request to the server when you change the HTML of your counter:
$("#update").click(function() {
$('#counter').html(function(i, val) {
$.ajax({
url: '/path/to/script/',
type: 'POST',
data: {increment: true},
success: function() { alert('Request has returned') }
});
return +val+1;
});
}
