Run Developer Command Prompt For V2012 or any version installed in your system
gacutil /i pathofDll
Enter
Done!!!
I had this problem too. I was trying to run an old 32-bit dll in a 64 bit system. I got it working by copying the .dll to the C:\Windows\SysWoW64\ directory and running this:
%systemroot%\SysWoW64\regsvr32 "C:\Windows\SysWoW64\thenameofyourdll.dll"
And also enabling IIS to run 32 bit apps
There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.
One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.
I had the same issue in a Windows Service. All keys where in the right place in the registry. The build of the service was done for x86 and I still got the exception. I found out about CorFlags.exe
Run this on your service.exe
without flags to verify if you run under 32 bit. If not run it with the flag /32BIT+ /Force
(Force only for signed assemblies)
If you have UAC turned you can get the following error: corflags : error CF001 : Could not open file for writing
Give the user full control on the assemblies.
Open the start menu and type cmd into the search box Hold Ctrl + Shift and press Enter
This runs the Command Prompt in Administrator mode.
Now type: regsvr32 MyComobject.dll
I recently ran into a problem with a UICommand not invoking in a JSF 1.2 application using IBM Extended Faces Components.
I had a command button on a row of a datatable (the extended version, so <hx:datatable>
) and the UICommand would not fire from certain rows from the table (the rows that would not fire were the rows greater than the default row display size).
I had a drop-down component for selecting number of rows to display. The value backing this field was in RequestScope
. The data backing the table itself was in a sort of ViewScope
(in reality, temporarily in SessionScope
).
If the row display was increased via the control which value was also bound to the datatable's rows
attribute, none of the rows displayed as a result of this change could fire the UICommand when clicked.
Placing this attribute in the same scope as the table data itself fixed the problem.
I think this is alluded to in BalusC #4 above, but not only did the table value need to be View or Session scoped but also the attribute controlling the number of rows to display on that table.

FIND
as a replacement for grep.
I hacked a little "phonebook" for myself with find. Very usefull:
@echo off
:begin
set /p term=Enter query:
type phonebookfile.txt |find /i "%term%"
if %errorlevel% == 0 GOTO :choose
echo No entry found
set /p new_entry=Add new entry:
echo %new_entry% >> phonebookfile.txt
:choose
set /p action=(q)uit, (n)ew query or (e)dit? [q]
if "%action%"=="n" GOTO anfang
if "%action%"=="e" (
notepad phonebookfile.txt
goto :choose
)
Very fast and effective.
Since this still comes up as a first answer in Google I'll contribute possible solution.

Check out this link it has a example code to encrypt/decrypt data using AES256CBC using EVP API.
https://github.com/saju/misc/blob/master/misc/openssl_aes.c
Also you can check the use of AES256 CBC in a detailed open source project developed by me at https://github.com/llubu/mpro
The code is detailed enough with comments and if you still need much explanation about the API itself i suggest check out this book Network Security with OpenSSL by Viega/Messier/Chandra (google it you will easily find a pdf of this..) read chapter 6 which is specific to symmetric ciphers using EVP API.. This helped me a lot actually understanding the reasons behind using various functions and structures of EVP.
and if you want to dive deep into the Openssl crypto library, i suggest download the code from the openssl website (the version installed on your machine) and then look in the implementation of EVP and aeh api implementation.
One more suggestion from the code you posted above i see you are using the api from aes.h instead use EVP. Check out the reason for doing this here OpenSSL using EVP vs. algorithm API for symmetric crypto nicely explained by Daniel in one of the question asked by me..
Use a wild card selector *
for this purpose.
#div * { /* Narrowing, to specific elements, like input, textarea is PREFFERED */
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
Now, every element inside a div with id div
will have no selection.
This is possible by creating the following link:

I have tested this on iOS, Windows Phone and Android
Would these work?
plt.scatter(np.random.randn(100), np.random.randn(100), facecolors='none')
or using plot()
plt.plot(np.random.randn(100), np.random.randn(100), 'o', mfc='none')

select @isSqlServer2005
Note : updated from original answer (see comment)
This is a follow up to my previous answer and contains C++11 related material..
Pre-requisites : An elementary knowledge of Relations (Mathematics).
Yes! This is very true.
Sequence Points have been replaced by Sequenced Before and Sequenced After (and Unsequenced and Indeterminately Sequenced) relations in C++11.
Sequenced Before(§1.9/13) is a relation which is:
between evaluations executed by a single thread and induces a strict partial order1
Formally it means given any two evaluations(See below) A
and B
, if A
is sequenced before B
, then the execution of A
shall precede the execution of B
. If A
is not sequenced before B
and B
is not sequenced before A
, then A
and B
are unsequenced 2.
Evaluations A
and B
are indeterminately sequenced when either A
is sequenced before B
or B
is sequenced before A
, but it is unspecified which3.
[NOTES]
1 : A strict partial order is a binary relation "<"
over a set P
which is asymmetric
, and transitive
, i.e., for all a
, b
, and c
in P
, we have that:
........(i). if a < b then ¬ (b < a) (asymmetry
);
........(ii). if a < b and b < c then a < c (transitivity
).
2 : The execution of unsequenced evaluations can overlap.
3 : Indeterminately sequenced evaluations cannot overlap, but either could be executed first.
In C++11, evaluation of an expression (or a sub-expression) in general includes:
value computations (including determining the identity of an object for glvalue evaluation and fetching a value previously assigned to an object for prvalue evaluation) and
initiation of side effects.
Now (§1.9/14) says:
Every value computation and side effect associated with a full-expression is sequenced before every value computation and side effect associated with the next full-expression to be evaluated.
Trivial example:
int x;
x = 10;
++x;
Value computation and side effect associated with ++x
is sequenced after the value computation and side effect of x = 10;
Yes! Right.
In (§1.9/15) it has been mentioned that
Except where noted, evaluations of operands of individual operators and of subexpressions of individual expressions are unsequenced4.
For example :
int main()
{
int num = 19 ;
num = (num << 3) + (num >> 3);
}
+
operator are unsequenced relative to each other.<<
and >>
operators are unsequenced relative to each other.4: In an expression that is evaluated more than once during the execution of a program, unsequenced and indeterminately sequenced evaluations of its subexpressions need not be performed consistently in different evaluations.
(§1.9/15) The value computations of the operands of an operator are sequenced before the value computation of the result of the operator.
That means in x + y
the value computation of x
and y
are sequenced before the value computation of (x + y)
.
More importantly
(§1.9/15) If a side effect on a scalar object is unsequenced relative to either
(a) another side effect on the same scalar object
or
(b) a value computation using the value of the same scalar object.
the behaviour is undefined.
Examples:
int i = 5, v[10] = { };
void f(int, int);
i = i++ * ++i; // Undefined Behaviour
i = ++i + i++; // Undefined Behaviour
i = ++i + ++i; // Undefined Behaviour
i = v[i++]; // Undefined Behaviour
i = v[++i]: // Well-defined Behavior
i = i++ + 1; // Undefined Behaviour
i = ++i + 1; // Well-defined Behaviour
++++i; // Well-defined Behaviour
f(i = -1, i = -1); // Undefined Behaviour (see below)
When calling a function (whether or not the function is inline), every value computation and side effect associated with any argument expression, or with the postfix expression designating the called function, is sequenced before execution of every expression or statement in the body of the called function. [Note: Value computations and side effects associated with different argument expressions are unsequenced. — end note]
Expressions (5)
, (7)
and (8)
do not invoke undefined behaviour. Check out the following answers for a more detailed explanation.

None of the methods listed scale the image to the largest possible size that fits in a box while retaining the desired aspect ratio.
This cannot be done with the IMG tag (at least not without a bit of JavaScript), but it can be done as follows:
<div style="background:center no-repeat url(...);background-size:contain;width:...;height:..."></div>
From the shell if you want to show all results you could do db.collection.find().toArray()
to get all results without it.
I have found the extend method of the Underscore.js library very useful when I want to pass in an object as a parameter which may either be modified or replaced entirely.
function replaceOrModify(aObj) {
if (modify) {
aObj.setNewValue('foo');
} else {
var newObj = new MyObject();
// _.extend(destination, *sources)
_.extend(newObj, aObj);
}
}
Timezones. You have to deal with them, by using getTimezoneOffset()
if you want your visitors from around the wolrd to get the same time.
Try this http://jsfiddle.net/cxyms/2/, it works for me, but I'm not sure will it work with other timezones.
var eventTimeStamp = '1366549200'; // Timestamp - Sun, 21 Apr 2013 13:00:00 GMT
var currentTimeStamp = '1366547400'; // Timestamp - Sun, 21 Apr 2013 12:30:00 GMT
var eventTime = new Date();
eventTime.setTime(366549200);
var Offset = new Date(eventTime.getTimezoneOffset()*60000)
var Diff = eventTimeStamp - currentTimeStamp + (Offset.getTime() / 2);
var duration = moment.duration(Diff, 'milliseconds');
var interval = 1000;
setInterval(function(){
duration = moment.duration(duration.asMilliseconds() - interval, 'milliseconds');
$('.countdown').text(moment(duration.asMilliseconds()).format('H[h]:mm[m]:ss[s]'));
}, interval);
Following worked for me:
Worked for me: Python 3.4, Django 1.10
In addition to the other answers, on a recent C library (Posix 2008 compliant), you could use getline. See this answer (to a related question).
I'll explain it in a simple way.
Generics defined at Class level are completely separate from the generics defined at the (static) method level.
class Greet<T> {
public static <T> void sayHello(T obj) {
System.out.println("Hello " + obj);
}
}
When you see the above code anywhere, please note that the T defined at the class level has nothing to do with the T defined in the static method. The following code is also completely valid and equivalent to the above code.
class Greet<T> {
public static <E> void sayHello(E obj) {
System.out.println("Hello " + obj);
}
}
Why the static method needs to have its own generics separate from those of the Class?
This is because, the static method can be called without even instantiating the Class. So if the Class is not yet instantiated, we do not yet know what is T. This is the reason why the static methods needs to have its own generics.
So, whenever you are calling the static method,
Greet.sayHello("Bob");
Greet.sayHello(123);
JVM interprets it as the following.
Greet.<String>sayHello("Bob");
Greet.<Integer>sayHello(123);
Both giving the same outputs.
Hello Bob
Hello 123
create a bash_profile at your user root - ex
/user/username/.bash_profile
open file
vim ~/.bash_profile
add alias as ex. (save and exit)
alias mydir="cd ~/Documents/dirname/anotherdir"
in new terminal just type mydir - it should open
/user/username/Documents/dirname/anotherdir
All you need is
plt.tight_layout()
before your output.
In addition to cutting down the margins, this also tightly groups the space between any subplots:
x = [1,2,3]
y = [1,4,9]
import matplotlib.pyplot as plt
fig = plt.figure()
subplot1 = fig.add_subplot(121)
subplot1.plot(x,y)
subplot2 = fig.add_subplot(122)
subplot2.plot(y,x)
fig.tight_layout()
plt.show()

With the lib config option your are able to cherry pick Map into your project. Just add es2015.collection
to your lib section. When you have no lib config add one with the defaults and add es2015.collection
.
So when you have target: es5, change tsconfig.json to:
"target": "es5",
"lib": [ "dom", "es5", "scripthost", "es2015.collection" ],
You can do this.
bonus_rows = []
for a in myarr:
if somecond(a):
bonus_rows.append(newObj())
myarr.extend( bonus_rows )

To remotely access database Mysql server 8:
CREATE USER 'root'@'%' IDENTIFIED BY 'Pswword@123';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
If the types of the parameters are all the same (varchar2
for example), you can have a package like this which will do the following:
CREATE OR REPLACE PACKAGE testuser.test_pkg IS
TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;
PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);
END test_pkg;
CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS
PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
BEGIN
FOR i IN p_parm.first .. p_parm.last
LOOP
dbms_output.put_line(p_parm(i));
END LOOP;
END;
END test_pkg;
Then, to call it you'd need to set up the array and pass it:
DECLARE
l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
l_array(0) := 'hello';
l_array(1) := 'there';
testuser.test_pkg.your_proc(l_array);
END;

<script type="text/javascript">

document.referrer

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.
You should use such a loop, that most fully conforms to your needs. For example:
for(int i = 0; i < 10; i++)
{
print(i);
}
//or
int i = 0;
while(i < 10)
{
print(i);
i++;
}
Obviously, in such situation, "for" looks better, than "while". And "do while" shoud be used when some operations must be done already before the moment when condition of your loop will be checked.
Sorry for my bad english).
Guys this is a generic method you can use for all your tables, Worked perfectly in my case.
public void deleteRowFromTable(String tableName, String columnName, String keyValue) {
String whereClause = columnName + "=?";
String[] whereArgs = new String[]{String.valueOf(keyValue)};
yourDatabase.delete(tableName, whereClause, whereArgs);
}
You could encode the binary data using base64 and put it into a Base64 element; the below article is a pretty good one on the subject.
select * from [Table_Name] limit 5
In Python, to represent the absence of a value, you can use the None
value types.NoneType.None
If you need to manipulate it on the client side, you can't use the Visible property on the server side. Instead, set its CSS display style to "none". For example:
<asp:Label runat="server" id="Label1" style="display: none;" />
Then, you could make it visible on the client side with:
document.getElementById('Label1').style.display = 'inherit';
You could make it hidden again with:
document.getElementById('Label1').style.display = 'none';
Keep in mind that there may be issues with the ClientID being more complex than "Label1" in practice. You'll need to use the ClientID with getElementById, not the server side ID, if they differ.
The c++ inline
keyword is misleading, it doesn't mean "inline this function". If a function is defined as inline, it simply means that it can be defined multiple times as long as all definitions are equal. It's perfectly legal for a function marked inline
to be a real function that is called instead of getting code inlined at the point where it's called.
Defining a function in a header file is needed for templates, since e.g. a templated class isn't really a class, it's a template for a class which you can make multiple variations of. In order for the compiler to be able to e.g. make a Foo<int>::bar()
function when you use the Foo template to create a Foo class, the actual definition of Foo<T>::bar()
must be visible.
From your question, I think it is safe to assume you have CASCADING DELETES turned on.
All that is needed in that case is
DELETE FROM MainTable
WHERE PrimaryKey = ???
You database engine will take care of deleting the corresponding referencing records.
for (var key in data) {
alert("User " + data[key] + " is #" + key); // "User john is #234"
}
If you create Makefile in the VSCode, your makefile doesnt run. I don't know the cause of this issue. Maybe the configuration of the file is not added to system. But I solved this way. delete created makefile, then go to project directory and right click mouse later create a file and named Makefile. After fill the Makefile and run it. It will work.
If you are using oc4j to deploy the ear.
Make sure you set in the project the correct path for deploy.home=
You can fiind deploy.home in common.properties file
The oc4j needs to reload the new created class in the ear so that the server class and the client class have the same serialVersionUID
You can literally convert it into float using:
float_value = float(integer_value)
Likewise, you can convert an integer back to float datatype with:
integer_value = int(float_value)
Hope it helped. I advice you to read "Build-In Functions of Python" at this link: https://docs.python.org/2/library/functions.html
You can use deparse
and substitute
to get the name of a function argument:
myfunc <- function(v1) {
deparse(substitute(v1))
}
myfunc(foo)
[1] "foo"
If you need the construct for a quick example to play with, use the : operator.
But if you are creating a vector/range of numbers dynamically, then use seq() instead.
Let's say you are creating the vector/range of numbers from a to b with a:b, and you expect it to be an increasing series. Then, if b is evaluated to be less than a, you will get a decreasing sequence but you will never be notified about it, and your program will continue to execute with the wrong kind of input.
In this case, if you use seq(), you can set the sign of the by argument to match the direction of your sequence, and an error will be raised if they do not match. For example,
seq(a, b, -1)
will raise an error for a=2, b=6, because the coder expected a decreasing sequence.
You can use .bind() to pass the param(this) to the function.
var someFunction =function(resolve, reject) {
/* get username, password*/
var username=this.username;
var password=this.password;
if ( /* everything turned out fine */ ) {
resolve("Stuff worked!");
} else {
reject(Error("It broke"));
}
}
var promise=new Promise(someFunction.bind({username:"your username",password:"your password"}));
Let's take a look at the stock hashCode() method:
public int hashCode() {
int h = hash;
if (h == 0 && count > 0) {
for (int i = 0; i < count; i++) {
h = 31 * h + charAt(i);
}
hash = h;
}
return h;
}
The block of code above comes from the java.lang.String class. As you can see it is a 32 bit hash code which fair enough if you are using it on a small scale of data. If you are looking for hash code with more than 32 bit, you might wanna checkout this link: http://www.javamex.com/tutorials/collections/strong_hash_code_implementation.shtml
From a security perspective, the safest thing to do when logging a user out is to reset all persistent state (e.x. cookies, localStorage
, IndexedDB
, Web SQL
, etc) and do a hard refresh of the page using window.location.reload()
. It's possible a sloppy developer accidentally or intentionally stored some sensitive data on window
, in the DOM, etc. Blowing away all persistent state and refreshing the browser is the only way to guarantee no information from the previous user is leaked to the next user.
(Of course, as a user on a shared computer you should use "private browsing" mode, close the browser window yourself, use the "clear browsing data" function, etc, but as a developer we can't expect everyone to always be that diligent)
As others have stated, the String
type in .NET is immutable and it's reference is passed by value.
In the original code, as soon as this line executes:
test = "after passing";
then test
is no longer referring to the original object. We've created a new String
object and assigned test
to reference that object on the managed heap.
I feel that many people get tripped up here since there's no visible formal constructor to remind them. In this case, it's happening behind the scenes since the String
type has language support in how it is constructed.
Hence, this is why the change to test
is not visible outside the scope of the TestI(string)
method - we've passed the reference by value and now that value has changed! But if the String
reference were passed by reference, then when the reference changed we will see it outside the scope of the TestI(string)
method.
Either the ref or out keyword are needed in this case. I feel the out
keyword might be slightly better suited for this particular situation.
class Program
{
static void Main(string[] args)
{
string test = "before passing";
Console.WriteLine(test);

You can rename your Conda env by just renaming the env folder. Here is the proof:
You can find your Conda env folder inside of C:\ProgramData\Anaconda3\envs
or you can enter conda env list
to see the list of conda envs and its location.
I was with the same problem in devices with SDK < 22, but for me the reason is the MultiDex, the MultiDex.install
must be in the attachBaseContext
method.
If you are using MultiDex, try this:
public class YourApplication extends Application {
@Override
protected void attachBaseContext(Context context) {
super.attachBaseContext(context);
MultiDex.install(this);
}
@Override
public void onCreate() {
super.onCreate();
Realm.init(this); //initialize other plugins
}
}

Declare your dim as a variant, and pull the data as you would from an array. i.e.
Dim y As Variant
y = Range("A1:B2")
Now your excel range is all 1 variable (array), y
To pull the data, call the array position in the range "A1:B2" or whatever you choose. e.g.:
Msgbox y(1, 1)
This will return the top left box in the "A1:B2" range.
If you can't use rgba

The idea behind StandardScaler
is that it will transform your data such that its distribution will have a mean value 0 and standard deviation of 1.
In case of multivariate data, this is done feature-wise (in other words independently for each column of the data).
Given the distribution of the data, each value in the dataset will have the mean value subtracted, and then divided by the standard deviation of the whole dataset (or feature in the multivariate case).
Another way to drop the index is to use a list comprehension:
df.columns = [col[1] for col in df.columns]
b c
0 1 2
1 3 4
This strategy is also useful if you want to combine the names from both levels like in the example below where the bottom level contains two 'y's:
cols = pd.MultiIndex.from_tuples([("A", "x"), ("A", "y"), ("B", "y")])
df = pd.DataFrame([[1,2, 8 ], [3,4, 9]], columns=cols)
A B
x y y
0 1 2 8
1 3 4 9
Dropping the top level would leave two columns with the index 'y'. That can be avoided by joining the names with the list comprehension.
df.columns = ['_'.join(col) for col in df.columns]
A_x A_y B_y
0 1 2 8
1 3 4 9
That's a problem I had after doing a groupby and it took a while to find this other question that solved it. I adapted that solution to the specific case here.
I had the same problem just now. I've fixed mine by adding a namespace on the app name. Hope someone find this helpful.

Why is floatval the best option for financial comparison data? bc functions only accurately turn strings into real numbers.
Code verified to work in Hibernate 4.3.0. Notice you can remove the XML filename parameter, or else provide your own path there. This is similar to (but typos corrected) other posts here, but this one is correct.
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
Configuration configuration = new Configuration();
configuration.configure("/com/rtw/test/hiber/hibernate.cfg.xml");
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
I got a easy solution which will select from database table and let you do easily.
SELECT b.FirstName + b.LastName FROM tbl_Users b WHERE b.Id='11'
You can easily add a space there if you try
SELECT b.FirstName +' '+ b.LastName FROM Users b WHERE b.Id='23'
Here you can combine as much as your table have.
In my case, it happenned for the master branch. Later found that my access to the project was accidentally revoked by the project manager. To cross-check, I visited the review site and couldn't see any commits of the said branch and others for that project.

In my case it was most trivial solution - I just needed to run Vistual Studio as Administrator.
It's trivial thing, but i didn't see this mentioned anywhere.
I seriously do think that it is code smell if you need to mock static methods, too.
The only time this seems overkill to me, is libs like Guava, but you shouldn't need to mock this kind anyway cause it's part of the logic... (stuff like Iterables.transform(..))
That way your own code stays clean, you can mock out all your dependencies in a clean way, and you have an anti corruption layer against external dependencies.
I've seen PowerMock in practice and all the classes we needed it for were poorly designed. Also the integration of PowerMock at times caused serious problems
(e.g. https://code.google.com/p/powermock/issues/detail?id=355)
PS: Same holds for private methods, too. I don't think tests should know about the details of private methods. If a class is so complex that it tempts to mock out private methods, it's probably a sign to split up that class...
The way to do it is to use NSAttributedString
like this:
NSMutableAttributedString *text =
[[NSMutableAttributedString alloc]
initWithAttributedString: label.attributedText];
[text addAttribute:NSForegroundColorAttributeName
value:[UIColor redColor]
range:NSMakeRange(10, 1)];
[label setAttributedText: text];
I created a UILabel
extension to do it.
Just do it simple (tested with v1.3.15):
<article ng-controller="ctrl1 as c1">
<label>Change name here:</label>
<input ng-model="c1.sData.name" />
<h1>Control 1: {{c1.sData.name}}, {{c1.sData.age}}</h1>
</article>
<article ng-controller="ctrl2 as c2">
<label>Change age here:</label>
<input ng-model="c2.sData.age" />
<h1>Control 2: {{c2.sData.name}}, {{c2.sData.age}}</h1>
</article>
<script>
var app = angular.module("MyApp", []);
var dummy = {name: "Joe", age: 25};
app.controller("ctrl1", function () {
this.sData = dummy;
});
app.controller("ctrl2", function () {
this.sData = dummy;
});
</script>

It
%%G
equal to some part of that dataIf you are using the FOR command at the command line rather than in a batch program, use just one percent sign: %G
instead of %%G
.
FOR Parameters
The first parameter has to be defined using a single character, for example the letter G.
FOR %%G IN
...
In each iteration of a FOR loop, the IN ( ....)
clause is evaluated and %%G
set to a different value
If this clause results in a single value then %%G is set equal to that value and the command is performed.
If the clause results in a multiple values then extra parameters are implicitly defined to hold each. These are automatically assigned in alphabetical order %%H %%I %%J
...(implicit parameter definition)
If the parameter refers to a file, then enhanced variable reference can be used to extract the filename/path/date/size.
You can of course pick any letter of the alphabet other than %%G
. but it is a good choice because it does not conflict with any of the pathname format letters (a, d, f, n, p, s, t, x) and provides the longest run of non-conflicting letters for use as implicit parameters.
This CSS worked for me:
.form-group.required.control-label:before{
color: red;
content: "*";
position: absolute;
margin-left: -10px;
}
and this HTML:
<div class="form-group required control-label">
<label for="emailField">Email</label>
<input type="email" class="form-control" id="emailField" placeholder="Type Your Email Address Here" />
</div>
Make sure to be careful when editing your model file. For example, in your post model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Post extends Model {
protected $table = 'posts';
}
You need to pay close attention to the class Post extend Model
line. The class Post
defined here will be your namespace for your controller.
DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);
assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.
The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.
As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.
If you need to parse other formats, you can check out the Standard DateTime Format Strings.
Try this one.. Source from here.

I use the following format and works well.

UPDATE: This doesn't answer the question as currently asked, but I'll leave it here for anyone looking for a simple answer to the original, non-descriptive question asked.
Create a custom Windows Service.
I had some mission-critical tasks set up as scheduled console apps and found them difficult to maintain. I created a Windows Service with a 'heartbeat' that would check a schedule in my DB every couple of minutes. It's worked out really well.
Having said that, I still use scheduled console apps for most of my non-critical maintenance tasks. If it ain't broke, don't fix it.
My guess is that you have a problem since you don't close your select-tag after the loop. Could that do the trick?
<select name="owner">
<?php
$sql = mysqli_query($connection, "SELECT username FROM users");
while ($row = $sql->fetch_assoc()){
echo "<option value=\"owner1\">" . $row['username'] . "</option>";
}
?>
</select>
The Chromium team is currently developing the Idle Detection API. It is available as an origin trial since Chrome 88, which is already the 2nd origin trial for this feature. An earlier origin trial went from Chrome 84 through Chrome 86.
It can also be enabled via a flag:
Enabling via chrome://flags
To experiment with the Idle Detection API locally, without an origin trial token, enable the
#enable-experimental-web-platform-features
flag in chrome://flags.
A demo can be found here:
It has to be noted though that this API is permission-based (as it should be, otherwise this could be misused to monitor a user's behaviour!).
-Xms initial heap size for the startup, however, during the working process the heap size can be less than -Xms due to users' inactivity or GC iterations. This is not a minimal required heap size.

The Groovy way to do this is
def list = []
list << new MyType(...)
which creates a list and uses the overloaded leftShift
operator to append an item
See the Groovy docs on Lists for lots of examples.
If you look at the JarFile API you'll see that it's a subclass of the ZipFile class.
The jar-specific classes mostly just add jar-specific functionality, like direct support for manifest file attributes and so on.
It's OOP "in action"; since jar files are zip files, the jar classes can use zip functionality and provide additional utility.
you have various ways to distinct values on one column or multi columns.

I wrote a module that can do this, called BFJ. Specifically, the method bfj.match
can be used to break up a large stream into discrete chunks of JSON:
const bfj = require('bfj');
const fs = require('fs');
const stream = fs.createReadStream(filePath);
bfj.match(stream, (key, value, depth) => depth === 0, { ndjson: true })
.on('data', object => {
// do whatever you need to do with object
})
.on('dataError', error => {
// a syntax error was found in the JSON
})
.on('error', error => {
// some kind of operational error occurred
})
.on('end', error => {
// finished processing the stream
});
Here, bfj.match
returns a readable, object-mode stream that will receive the parsed data items, and is passed 3 arguments:
A readable stream containing the input JSON.
A predicate that indicates which items from the parsed JSON will be pushed to the result stream.
An options object indicating that the input is newline-delimited JSON (this is to process format B from the question, it's not required for format A).
Upon being called, bfj.match
will parse JSON from the input stream depth-first, calling the predicate with each value to determine whether or not to push that item to the result stream. The predicate is passed three arguments:
The property key or array index (this will be undefined
for top-level items).
The value itself.
The depth of the item in the JSON structure (zero for top-level items).
Of course a more complex predicate can also be used as necessary according to requirements. You can also pass a string or a regular expression instead of a predicate function, if you want to perform simple matches against property keys.
t = (1, 2, 3)
# the comma (,) concatenates the strings and adds a space
print "this is a tuple", (t)
# format is the most flexible way to do string formatting
print "this is a tuple {0}".format(t)
# classic string formatting
# I use it only when working with older Python versions
print "this is a tuple %s" % repr(t)
print "this is a tuple %s" % str(t)
I had the same problem. I tried everything listed on this page. When I re-installed Composer it worked like before. I had a PHP version mismatch that was corrected with a new install establishing the dependencies with the PHP path installed in my system environment variables.
I DO NOT RECOMMEND the composer config -g -- disable-tls true
approach.
By the way the way to reverse this is composer config -g -- disable-tls false
.
MyFragment fragment = (MyFragment) getSupportFragmentManager().findFragmentByTag(FRAGMENT_TAG);
getSupportFragmentManager().beginTransaction().detach(fragment).attach(fragment).commit();
this will only work if u use FragmentManager
to initialize the fragment. If u have it as a <fragment ... />
in XML, it won't call the onCreateView
again. Wasted my 30 minutes to figure this out.
Technically, 'char
' could have the same range as either 'signed char
' or 'unsigned char
'. For the unsigned characters, your range is correct; theoretically, for signed characters, your condition is wrong. In practice, very few compilers will object - and the result will be the same.
Nitpick: the last &&
in the assert
is a syntax error.
Whether the assertion is appropriate depends on whether you can afford to crash when the code gets to the customer, and what you could or should do if the assertion condition is violated but the assertion is not compiled into the code. For debug work, it seems fine, but you might want an active test after it for run-time checking too.
You can use regular expressions for this, so I think this is what you want:
select t.*
from test t
where not regexp_like(sampletext, '.*[^a-zA-Z0-9 .{}\[\]].*')
Well... I see that an answer was already accepted... but I think you should see another solutions anyway:
/* EXAMPLE */
DECLARE @UserAliases TABLE(UserId INT , Alias VARCHAR(10))
INSERT INTO @UserAliases (UserId,Alias) SELECT 1,'MrX'
UNION ALL SELECT 1,'MrY' UNION ALL SELECT 1,'MrA'
UNION ALL SELECT 2,'Abc' UNION ALL SELECT 2,'Xyz'
/* QUERY */
;WITH tmp AS ( SELECT DISTINCT UserId FROM @UserAliases )
SELECT
LEFT(tmp.UserId, 10) +
'/ ' +
STUFF(
( SELECT ', '+Alias
FROM @UserAliases
WHERE UserId = tmp.UserId
FOR XML PATH('')
)
, 1, 2, ''
) AS [UserId/Alias]
FROM tmp
/* -- OUTPUT
UserId/Alias
1/ MrX, MrY, MrA
2/ Abc, Xyz
*/
Try this one if you want to create a virtual column "age" within a select statement:
select brand, name, "10" as age from cars...
The solution I use is to connect to the host over SSH
and execute the command like this:
ssh -l ${USERNAME} ${HOSTNAME} "${SCRIPT}"
As this answer keeps getting up votes, I would like to remind (and highly recommend), that the account which is being used to invoke the script should be an account with no permissions at all, but only executing that script as sudo
(that can be done from sudoers
file).
You also can use Gnuplot
which is also available from gretl
. Put your x y z data on a text file an insert the following
splot 'test.txt' using 1:2:3 with points palette pointsize 3 pointtype 7
Then you can set labels, etc. using
set xlabel "xxx" rotate parallel
set ylabel "yyy" rotate parallel
set zlabel "zzz" rotate parallel
set grid
show grid
unset key
I would use these polyfill https://github.com/WebReflection/ie8

You can use Oracle's SQL Developer tool to do that (My Oracle DB version is 11). While creating a table choose Advanced option and click on the Identity Column tab at the bottom and from there choose Column Sequence. This will generate a AUTO_INCREMENT column (Corresponding Trigger and Squence) for you.
deleteRequest: function (url, Id, bolDeleteReq, callback, errorCallback) {
$.ajax({
url: urlCall,
type: 'DELETE',
data: {"Id": Id, "bolDeleteReq" : bolDeleteReq},
success: callback || $.noop,
error: errorCallback || $.noop
});
}
Note: the use of headers
was introduced in JQuery 1.5.:
A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.
I usually use either komodo edit or aquamacs with ropemacs. Although I should warn you, IDE features won't be what you're used to if you're coming from a Java or C# background. I personally find that powerful IDEs get in my way more than they help.
UPDATE: I should also point out that if you have the money Komodo IDE is worth it. It's the paid version of Komodo Edit.
Adding to the accepted answer, further optimization can be achieved by using a list to store primes and printing them after generation.
import math
Primes_Upto = 101
Primes = [2]
for num in range(3,Primes_Upto,2):
if all(num%i!=0 for i in Primes):
Primes.append(num)
for i in Primes:
print i
use the reset method of Path class
Path.reset();
Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.
In one case, I found that query
worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.
I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query
could be faster than prepare
& execute
because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.
Given a couple rare conditions:
If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.
If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.
PDO::lastInsertId
is not supported by the Microsoft ODBC driver.
Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:
To start, I've created a basic table in Microsoft SQL Server
CREATE TABLE performancetest (
sid INT IDENTITY PRIMARY KEY,
id INT,
val VARCHAR(100)
);
And now a basic timed test for performance metrics.
$logs = [];
$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
$start = microtime(true);
$i = 0;
while ($i < $count) {
$sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
if ($type === 'query') {
$smt = $pdo->query($sql);
} else {
$smt = $pdo->prepare($sql);
$smt ->execute();
}
$sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
$i++;
}
$total = (microtime(true) - $start);
$logs[$type] []= $total;
echo "$total $type\n";
};
$trials = 15;
$i = 0;
while ($i < $trials) {
if (random_int(0,1) === 0) {
$test('query');
} else {
$test('prepare');
}
$i++;
}
foreach ($logs as $type => $log) {
$total = 0;
foreach ($log as $record) {
$total += $record;
}
$count = count($log);
echo "($count) $type Average: ".$total/$count.PHP_EOL;
}
I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query
than prepare
/execute
5.8128969669342 prepare
5.8688418865204 prepare

I'm curious to see how this test compares in other environments, like MySQL.
I don't think your going to get valueOf("Start Here") to work. But as far as spaces...try the following...
static private enum RandomEnum {
R("Start There"),
G("Start Here");
String value;
RandomEnum(String s) {
value = s;
}
}
System.out.println(RandomEnum.G.value);
System.out.println(RandomEnum.valueOf("G").value);
Start Here
Start Here
So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]
I'd suggest:
document.querySelector('.rateRecipe.btns-one-small').click();
The above code assumes that the given element has both of those classes; otherwise, if the space is meant to imply an ancestor-descendant relationship:
document.querySelector('.rateRecipe .btns-one-small').click();
The method getElementsByClassName()
takes a single class-name (rather than document.querySelector()
/document.querySelectorAll()
, which take a CSS selector), and you passed two (presumably class-names) to the method.

If your html file resides locally then go for iframe instead of the tag. tags do not work cross-browser, and are mostly used for Flash
For ex : <iframe src="home.html" width="100" height="100"/>
What is the exact contents you are passing into $html_brand?
If it is has an invalid URL syntax, you will very likely get the HTTP code 0.
I had the same problem and the only thing that works for my was to uninstall entity framework package from each project using Uninstall-Package. And then intall it again in the whole solution. It will ask you to choose in which project you want to install it, you shall select all.
I didn't realise from your original question that you were opening a file on the local machine, I thought you were sending a file from the web server to the client.
Based on your screenshot, try formatting your link like so:
<a href="file:///C:/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">Klik hier</a>
(without knowing the contents of each of your recordset variables I can't give you the exact ASP code)
Also, if you can't change class B, you can fix the error by using multiple inheritance.
class B:
def meth(self, arg):
print arg
class C(B, object):
def meth(self, arg):
super(C, self).meth(arg)
print C().meth(1)
This question has already been answered. I'd like to extend the answer from @amd. Sometimes you might need a default value.
For example, to validate against a specific value, I'd like to provide it as follows-
<input integerMinValue="20" >
But the minimum value of a 32 bit signed integer is -2147483648. To validate against this value, I don't like to provide it. I'd like to write as follows-
<input integerMinValue >
To achieve this you can write your directive as follows
import {Directive, Input} from '@angular/core';
import {AbstractControl, NG_VALIDATORS, ValidationErrors, Validator, Validators} from '@angular/forms';
@Directive({
selector: '[integerMinValue]',
providers: [{provide: NG_VALIDATORS, useExisting: IntegerMinValidatorDirective, multi: true}]
})
export class IntegerMinValidatorDirective implements Validator {
private minValue = -2147483648;
@Input('integerMinValue') set min(value: number) {
if (value) {
this.minValue = +value;
}
}
validate(control: AbstractControl): ValidationErrors | null {
return Validators.min(this.minValue)(control);
}
}
If you define your variable using declare (old: typeset) then you can state the case of the value throughout the variable's use.
$ declare -u FOO=AbCxxx
$ echo $FOO
ABCXXX
"-l"
does lc.
From MSDN:
To maximize productivity, the Windows Forms Designer shadows the
AutoSize
property for theForm
class. At design time, the form behaves as though theAutoSize
property is set to false, regardless of its actual setting. At runtime, no special accommodation is made, and theAutoSize
property is applied as specified by the property setting.
Regarding the concept “user agent style sheet”, consult section Cascade in the CSS 2.1 spec.
User agent style sheets are overridden by anything that you set in your own style sheet. They are just the rock bottom: in the absence of any style sheets provided by the page or by the user, the browser still has to render the content somehow, and the user agent style sheet just describes this.
So if you think you have a problem with a user agent style sheet, then you really have a problem with your markup, or your style sheet, or both (about which you wrote nothing).
$(document).ready(function () {
toggleFields(); // call this first so we start out with the correct visibility depending on the selected form values
// this will call our toggleFields function every time the selection value of our other field changes
$("#dbType").change(function () {
toggleFields();
});
});
// this toggles the visibility of other server
function toggleFields() {
if ($("#dbType").val() === "other")
$("#otherServer").show();
else
$("#otherServer").hide();
}
HTML:
<p>Choose type</p>
<p>Server:
<select id="dbType" name="dbType">
<option>Choose Database Type</option>
<option value="oracle">Oracle</option>
<option value="mssql">MS SQL</option>
<option value="mysql">MySQL</option>
<option value="other">Other</option>
</select>
</p>
<div id="otherServer">
<p>Server:
<input type="text" name="server_name" />
</p>
<p>Port:
<input type="text" name="port_no" />

Do your databinding and then add the following:
Dim liFirst As New ListItem("", "")
drpList.Items.Insert(0, liFirst)
Following code is working for me.

{
using (Stream responseStream = response.GetResponseStream())
{
using (StreamReader responseReader = new StreamReader(responseStream))
{
string json = responseReader.ReadToEnd();
string data = JObject.Parse(json)["id"].ToString();
}
}
}
//json = {"kind": "ALL", "id": "1221455", "longUrl": "NewURL"}
I had the same error. In my case, using Appium, I had two versions of ADB
$ /usr/local/bin/adb
version 36
and
$ /Users/user/Library/Android/sdk/platform-tools/adb
version 39
The solution was:
be sure that your $PATH in bash_profile is pointing to: /Users/user/Library/Android/sdk/platform-tools/
stop the adb server: adb kill-server
and check Appium is stopped.
delete the adb version 36 (or you can rename it to have a backup): rm /usr/local/bin/adb
start adb server: adb start-server
or just starting Appium
Haven't used Python in several years, but I would say that it has more to do with it being a dynamically typed language than anything else. For a simple example, in Java, if I wanted to test that something wrote to standard out appropriately I could use DI and pass in any PrintStream to capture the text being written and verify it. When I'm working in Ruby, however, I can dynamically replace the 'puts' method on STDOUT to do the verify, leaving DI completely out of the picture. If the only reason I'm creating an abstraction is to test the class that's using it (think File system operations or the clock in Java) then DI/IoC creates unnecessary complexity in the solution.
use the redrawAll() function rather than renderAll().
Straight from the Java Language Specification:
A method that is
native
is implemented in platform-dependent code, typically written in another programming language such as C, C++, FORTRAN,or assembly language. The body of anative
method is given as a semicolon only, indicating that the implementation is omitted, instead of a block.
You probably included your JavaScript before the HTML: example.
You should either execute your JavaScript when the window loads (or better, when the DOM is fully loaded), or you should include your JavaScript after your HTML: example.

I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.
The dash type of a linestyle
is given by the linetype
, which does also select the line color unless you explicitely set an other one with linecolor
.
However, the support for dashed lines depends on the selected terminal:
png
(uses libgd
)pngcairo
, support dashed lines, but it is disables by default. To enable it, use set termoption dashed
, or set terminal pngcairo dashed ...
.linetype
, use the test
command:Running
set terminal pngcairo dashed
set output 'test.png'
test
set output
gives:
whereas, the postscript
terminal shows different dash patterns:
set terminal postscript eps color colortext
set output 'test.eps'
test
set output
Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:
A new dashtype
parameter was introduced:
To get the predefined dash patterns, use e.g.
plot x dashtype 2
You can also specify custom dash patterns like
plot x dashtype (3,5,10,5),\
2*x dashtype '.-_'
The terminal options dashed
and solid
are ignored. By default all lines are solid. To change them to dashed, use e.g.
set for [i=1:8] linetype i dashtype i
The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic
:
You could use an existing hash algorithm that produces something short, like MD5 (128 bits) or SHA1 (160). Then you can shorten that further by XORing sections of the digest with other sections. This will increase the chance of collisions, but not as bad as simply truncating the digest.
Also, you could include the length of the original data as part of the result to make it more unique. For example, XORing the first half of an MD5 digest with the second half would result in 64 bits. Add 32 bits for the length of the data (or lower if you know that length will always fit into fewer bits). That would result in a 96-bit (12-byte) result that you could then turn into a 24-character hex string. Alternately, you could use base 64 encoding to make it even shorter.
Source link: http://www.codeblocq.com/2016/01/Untrack-files-already-added-to-git-repository-based-on-gitignore/
Let’s say you have already added/committed some files to your git repository and you then add them to your .gitignore; these files will still be present in your repository index. This article we will see how to get rid of them.
Before proceeding, make sure all your changes are committed, including your .gitignore file.
To clear your repo, use:
git rm -r --cached .
The rm
command can be unforgiving. If you wish to try what it does beforehand, add the -n
or --dry-run
flag to test things out.
git add .
git commit -m ".gitignore fix"
Your repository is clean :)
Push the changes to your remote to see the changes effective there as well.
My solution, (using jquery):
<iframe id="Iframe1" class="tabFrame" width="100%" height="100%" scrolling="no" src="http://samedomain" frameborder="0" >
</iframe>
<script type="text/javascript">
$(function () {
$('.tabFrame').load(function () {
var iframeContentWindow = this.contentWindow;
var height = iframeContentWindow.$(document).height();
this.style.height = height + 'px';
});
});
</script>
In Python 2.x, it is not guaranteed at all:
>>> False = 5
>>> 0 == False
False
So it could change. In Python 3.x, True, False, and None are reserved words, so the above code would not work.
In general, with booleans you should assume that while False will always have an integer value of 0 (so long as you don't change it, as above), True could have any other value. I wouldn't necessarily rely on any guarantee that True==1
, but on Python 3.x, this will always be the case, no matter what.
According to the javadoc a Scanner
does not seem to be intended for reading single characters. You attach a Scanner
to an InputStream
(or something else) and it parses the input for you. It also can strip of unwanted characters. So you can read numbers, lines, etc. easily. When you need only the characters from your input, use a InputStreamReader for example.
Following @Tobu answer and @mipadi comment, in a more pythonic way, if not interested in the created flag, I would use:
customer.source, _ = Source.objects.get_or_create(name="Website")
In the v-model the value of the property might not be a strict boolean value and the checkbox might not 'recognise' the value as checked/unchecked. There is a neat feature in VueJS to make the conversion to true or false:
<input
type="checkbox"
v-model="toggle"
true-value="yes"
false-value="no"
>
If you're clearing the list, you, obviously, don't need the list anymore. If so, you can just delete the entire list by simple del method.
a = [1, 3, 5, 6]
del a # This will entirely delete a(the list).
But in case, you need it again, you can reinitialize it. Or just simply clear its elements by
del a[:]
If you need just quick dump and don't want to implement custom encoder. You can use the following:
json_string = json.dumps(data, iterable_as_array=True)
This will convert all sets (and other iterables) into arrays. Just beware that those fields will stay arrays when you parse the json back. If you want to preserve the types, you need to write custom encoder.
If you want the name, use Martin's method. If you want to know whether it's an instance of a certain class:
boolean b = a instanceof String
In my case, the svn relocate
command (as well as svn switch --relocate
) failed for some reason (maybe the repo was not moved correctly, or something else). I faced this error:
$ svn relocate NEW_SERVER
svn: E195009: The repository at 'NEW_SERVER' has uuid 'e7500204-160a-403c-b4b6-6bc4f25883ea', but the WC has '3a8c444c-5998-40fb-8cb3-409b74712e46'
I did not want to redownload the whole repository, so I found a workaround. It worked in my case, but generally I can imagine a lot of things can get broken (so either backup your working copy, or be ready to re-checkout the whole repo if something goes wrong).
The repo address and its UUID are saved in the .svn/wc.db
SQLite database file in your working copy. Just open the database (e.g. in SQLite Browser), browse table REPOSITORY, and change the root
and uuid
column values to the new ones. You can find the UUID of the new repo by issuing svn info NEW_SERVER
.
Again, treat this as a last resort method.
Remember that if you are using a proxy you need to do a little trick in your php code:

'request_fulluri' => true,
),
);
$cxContext = stream_context_create($aContext);

echo $sFile;

Make sure to use the latest npm version while installing packages using npm.
While installing JavaScript, mention the latest version of NodeJS. For example, while installing JavaScript using devtools, use the below code:
devtools i --javascript nodejs:10.15.1
This will download and install the mentioned NodeJS version. Try installing the packages with npm after updating the version. This worked for me.
I believe you should do
dice1 = arc4random_uniform(6) + 1;
to get the range 1 - 6. I don't do iOS objective C nor have I any knowledge on swift-language though. The random method should return a value between 0 and 5, and + 1 will make it a value between 1 and 6.
If you need a range between lets say 10 - 30 then just do
int random = arc4random_uniform(21) + 10;

Just copy and paste the code in your css.
If you just want the last date for each account, you'd use this:
var q = from n in table
group n by n.AccountId into g
select new {AccountId = g.Key, Date = g.Max(t=>t.Date)};
If you want the whole record:
var q = from n in table
group n by n.AccountId into g
select g.OrderByDescending(t=>t.Date).FirstOrDefault();
You use the "as" statement to avoid the possibility of an exception, e.g. you can handle the cast failure gracefully via logic. Only use the cast when you are sure that the object is of the desired type. I almost always use the "as" and then check for null.
This CSS also shows a fixed height HTML table. It sets the height of the HTML tbody to 400 pixels and the HTML tbody scrolls when the it is larger, retaining the HTML thead as a non-scrolling element.
In addition, each th cell in the heading and each td cell the body should be styled for the desired fixed width.
#the-table {
display: block;
background: white; /* optional */
}
#the-table thead {
text-align: left; /* optional */
}
#the-table tbody {
display: block;
max-height: 400px;
overflow-y: scroll;
}
This will work with any object:
var util = require("util");
console.log(util.inspect(myObject, {showHidden: false, depth: null}));

Acording to the docs:
Note The urllib2 module has been split across several modules in Python 3 named
urllib.request
andurllib.error
. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.
So it appears that it is impossible to do what you want but you can use appropriate python3 functions from urllib.request
.
One of the best options is to go for MongoDB(NOSql dB) that supports scalability.Stores large amounts of data nothing but bigdata in the form of documents unlike rows and tables in sql.This is fasters that follows sharding of the data.Uses replicasets to ensure data guarantee that maintains multiple servers having primary db server as the base.

I have had to use code like this to provide functions to allocate memory to a pointer passed in and return its size because my company "object" to me using the STL
int iSizeOfArray(int* &piArray) {
piArray = new int[iNumberOfElements];
...
return iNumberOfElements;
}
It is not nice, but the pointer must be passed by reference (or use double pointer). If not, memory is allocated to a local copy of the pointer if it is passed by value which results in a memory leak.

They really make you run around the barn to do it with the GUI:

Yes. You can use reflection. Something like this:

theMethod.Invoke(this, userParameters);

You can do it even without the HTTP_PROXY environment variable. Try this sample:
import urllib2
proxy_support = urllib2.ProxyHandler({"http":"http://61.233.25.166:80"})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
html = urllib2.urlopen("http://www.google.com").read()
print html
In your case it really seems that the proxy server is refusing the connection.
Something more to try:
import urllib2
#proxy = "61.233.25.166:80"
proxy = "YOUR_PROXY_GOES_HERE"
proxies = {"http":"http://%s" % proxy}
url = "http://www.google.com/search?q=test"
headers={'User-agent' : 'Mozilla/5.0'}
proxy_support = urllib2.ProxyHandler(proxies)
opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler(debuglevel=1))
urllib2.install_opener(opener)
req = urllib2.Request(url, None, headers)
html = urllib2.urlopen(req).read()
print html
Edit 2014:
This seems to be a popular question / answer. However today I would use third party requests
module instead.
For one request just do:
import requests
r = requests.get("http://www.google.com",
proxies={"http": "http://61.233.25.166:80"})
print(r.text)
For multiple requests use Session
object so you do not have to add proxies
parameter in all your requests:
import requests
s = requests.Session()
s.proxies = {"http": "http://61.233.25.166:80"}
r = s.get("http://www.google.com")
print(r.text)
double a = 13.34;
int b = (int) a;
System.out.println(b); //prints 13
"Empty": only works on variables. Empty can mean different things for different variable types (check manual: http://php.net/manual/en/function.empty.php).
"isset": checks if the variable exists and checks for a true NULL or false value. Can be unset by calling "unset". Once again, check the manual.
Use of either one depends of the variable type you are using.
I would say, it's safer to check for both, because you are checking first of all if the variable exists, and if it isn't really NULL or empty.
You can always use the definition of xor to compute it from other logical operations:
(a and not b) or (not a and b)
But this is a little too verbose for me, and isn't particularly clear at first glance. Another way to do it is:
bool(a) ^ bool(b)
The xor operator on two booleans is logical xor (unlike on ints, where it's bitwise). Which makes sense, since bool
is just a subclass of int
, but is implemented to only have the values 0
and 1
. And logical xor is equivalent to bitwise xor when the domain is restricted to 0
and 1
.
So the logical_xor
function would be implemented like:
def logical_xor(str1, str2):
return bool(str1) ^ bool(str2)

mysqli_error()
As in:
$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);
Trigger error is better than die because you can use it for development AND production, it's the permanent solution.
With R 3.6.1, I can do the following
fr2v <- function() { c(5,3) }
a_b <- fr2v()
(a_b[[1]]) # prints "5"
(a_b[[2]]) # prints "3"
I had a similar issue with the iteration and I landed here. Maybe someone else is also doing the same mistake I did.
In my case, the selector was not the problem at all. The problem was that I had messed up the javascript code:
I had a loop and a subloop. The subloop was also using i
as a counter, instead of j
, so because the subloop was overriding the value of i
of the main loop, this one never got to the second iteration.
var dayContainers = document.getElementsByClassName('day-container');
for(var i = 0; i < dayContainers.length; i++) { //loop of length = 2
var thisDayDiv = dayContainers[i];
// do whatever
var inputs = thisDayDiv.getElementsByTagName('input');
for(var j = 0; j < inputs.length; j++) { //loop of length = 4
var thisInput = inputs[j];
// do whatever
};
};
Here is the correct implementation using numpy (np.log()
is the natural logarithm)
import numpy as np
p = 100
r = 0.06 / 12
FV = 4000
n = np.log(1 + FV * r/ p) / np.log(1 + r)
print ("Number of periods = " + str(n))

If you need to store the ZIP Code in a character array, zipcode[]
, you can use this:
snprintf(zipcode, 6, "%05.5d", atoi(zipcode));
There is another way of doing so:
<span style="width: 10px"></span>
You can adjust the amount of space using the width property.
Your code would be:
<div style="text-align: center">
<asp:Button ID="btnSubmit" runat="server" Text="Submit" Width="89px" OnClick="btnSubmit_Click" />
<span style="width: 10px"></span>
<asp:Button ID="btnClear" runat="server" Text="Clear" Width="89px" OnClick="btnClear_Click" />
</div>
I had the same problem. I'm using DB2. What I have done is a bit not too professional solution, but it works in every DBMS:
ALTER TABLE USERS ADD COLUMN LOGIN_OLD VARCHAR(50) NOT NULL DEFAULT '';
UPDATE USERS SET LOGIN_OLD=LOGIN;
ALTER TABLE USERS DROP COLUMN LOGIN;
ALTER TABLE USERS RENAME COLUMN LOGIN_OLD TO LOGIN;
CALL SYSPROC.ADMIN_CMD('REORG TABLE USERS');
The syntax of the ALTER commands may be different in other DBMS
Look into the String#capitalize method.
http://www.ruby-doc.org/core-1.9.3/String.html#method-i-capitalize
Since the number of columns is a constant, you can just have an List
of int[]
.
import java.util.*;
//...
List<int[]> rowList = new ArrayList<int[]>();
rowList.add(new int[] { 1, 2, 3 });
rowList.add(new int[] { 4, 5, 6 });
rowList.add(new int[] { 7, 8 });
for (int[] row : rowList) {
System.out.println("Row = " + Arrays.toString(row));
} // prints:
// Row = [1, 2, 3]
// Row = [4, 5, 6]
// Row = [7, 8]
System.out.println(rowList.get(1)[1]); // prints "5"
Since it's backed by a List
, the number of rows can grow and shrink dynamically. Each row is backed by an int[]
, which is static, but you said that the number of columns is fixed, so this is not a problem.
To search for files in /target_directory and all its sub-directories, that have been modified in the last 60 minutes:
$ find /target_directory -type f -mmin -60
To find the most recently modified files, sorted in the reverse order of update time (i.e., the most recently updated files first):
$ find /etc -type f -printf '%TY-%Tm-%Td %TT %p\n' | sort -r
The currently preferred (Exchange 2013 and 2016) API is EWS. It is purely HTTP based and can be accessed from any language, but there are .Net and Java specific libraries.
You can use EWSEditor to play with the API.
Extended MAPI. This is the native API used by Outlook. It ends up using the MSEMS
Exchange MAPI provider, which can talk to Exchange using RPC (Exchange 2013 no longer supports it) or RPC-over-HTTP (Exchange 2007 or newer) or MAPI-over-HTTP (Exchange 2013 and newer).
The API itself can only be accessed from unmanaged C++ or Delphi. You can also use Redemption (any language) - its RDO family of objects is an Extended MAPI wrapper. To use Extended MAPI, you need to install either Outlook or the standalone (Exchange) version of MAPI (on extended support, and it does not support Unicode PST and MSG files and cannot access Exchange 2016). Extended MAPI can be used in a service.
You can play with the API using OutlookSpy or MFCMAPI.
Outlook Object Model - not Exchange specific, but it allows access to all data available in Outlook on the machine where the code runs. Cannot be used in a service.
Exchange Active Sync. Microsoft no longer invests any significant resources into this protocol.
Outlook used to install CDO 1.21 library (it wraps Extended MAPI), but it had been deprecated by Microsoft and no longer receives any updates.
There used to be a third-party .Net MAPI wrapper called MAPI33, but it is no longer being developed or supported.
WebDAV - deprecated.
Collaborative Data Objects for Exchange (CDOEX) - deprecated.
Exchange OLE DB Provider (EXOLEDB) - deprecated.
There is an easy way, just remove the symbolic link from "/usr/bin". It will work.
I too had that same problem.. If we think logically little bit we can get the answer.. It worked for me very well.. I hope u will get it..

as we setting the value to TextView

object returned by onItemClick
method. OnItemClick()
returns the current view.
TextView v=(TextView) view.findViewById(R.id.txtLstItem);

Using this simple logic we can get other values like CheckBox

To check if a file doesn't exist, equivalent to Python's if not os.path.exists(filename)
:
if _, err := os.Stat("/path/to/whatever"); os.IsNotExist(err) {
// path/to/whatever does not exist
}
To check if a file exists, equivalent to Python's if os.path.exists(filename)
:
Edited: per recent comments
if _, err := os.Stat("/path/to/whatever"); err == nil {
// path/to/whatever exists
} else if os.IsNotExist(err) {
// path/to/whatever does *not* exist
} else {
// Schrodinger: file may or may not exist. See err for details.
// Therefore, do *NOT* use !os.IsNotExist(err) to test for file existence
}
As @daniel-t points out in the comment: github.com/docker/docker/issues/2174 is about showing binding only to IPv6 in netstat
, but that is not an issue. As that github issues states:
When setting up the proxy, Docker requests the loopback address '127.0.0.1', Linux realises this is an address that exists in IPv6 (as ::0) and opens on both (but it is formally an IPv6 socket). When you run netstat it sees this and tells you it is an IPv6 - but it is still listening on IPv4. If you have played with your settings a little, you may have disabled this trick Linux does - by setting net.ipv6.bindv6only = 1.
In other words, just because you see it as IPv6 only, it is still able to communicate on IPv4 unless you have IPv6 set to only bind on IPv6 with the net.ipv6.bindv6only setting. To be clear, net.ipv6.bindv6only should be 0 - you can run sysctl net.ipv6.bindv6only
to verify.
Just make it simple without third party libraries:
final String source = "FooBar";
final String target = "Foo";
final String replacement = "";
final String result = Pattern.compile(target, Pattern.LITERAL | Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE).matcher(source)
.replaceAll(Matcher.quoteReplacement(replacement));
RDP will not do that natively.
As other answers have said -- you'll need to do some scripting and make policy changes as a kludge to make it hard for RDP logins to run anything but the intended application.
However, as of 2008, Microsoft has released application virtualization technology via Terminal Services that will allow you to do this seamlessly.
def scrollToElement(element: WebElement) = {
val location = element.getLocation
driver.asInstanceOf[JavascriptExecutor].executeScript(s"window.scrollTo(${location.getX},${location.getY});")

I just removed all the private libraries in JavaBuildPath and added the jars again.. It worked
Based on user3676011 answer, I can suggest more detailed one with small correction. This solution works great on Swift 2.0.
enum CollectionViewContentPosition {
case Left
case Center
}
var collectionViewContentPosition: CollectionViewContentPosition = .Left
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout,
insetForSectionAtIndex section: Int) -> UIEdgeInsets {
if collectionViewContentPosition == .Left {
return UIEdgeInsetsZero
}
// Center collectionView content
let itemsCount: CGFloat = CGFloat(collectionView.numberOfItemsInSection(section))
let collectionViewWidth: CGFloat = collectionView.bounds.width
let itemWidth: CGFloat = 40.0
let itemsMargin: CGFloat = 10.0
let edgeInsets = (collectionViewWidth - (itemsCount * itemWidth) - ((itemsCount-1) * itemsMargin)) / 2
return UIEdgeInsetsMake(0, edgeInsets, 0, 0)
}
There was an issue in
(CGFloat(elements.count) * 10))
where should be additional -1
mentioned.
If the range of the numbers is limited (there can be only mod 2 8 digit numbers, or only 10 different 8 digit numbers for example), then you could write an optimized sorting algorithm. But if you want to sort all possible 8 digit numbers, this is not possible with that low amount of memory.
Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.
This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".
Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
strXls, True, "temp!"
Put the following code before int main()
:
using namespace std;
And you will be able to use cout
.
For example:
#include<iostream>
using namespace std;
int main(){
char t = 'f';
char *t1;
char **t2;
cout<<t;
return 0;
}
Now take a moment and read up on what cout is and what is going on here: http://www.cplusplus.com/reference/iostream/cout/
Further, while its quick to do and it works, this is not exactly a good advice to simply add using namespace std;
at the top of your code. For detailed correct approach, please read the answers to this related SO question.
This will give you the date in 24 hour format.
Date date = new Date();
date.setHours(date.getHours() + 8);
System.out.println(date);
SimpleDateFormat simpDate;
simpDate = new SimpleDateFormat("kk:mm:ss");
System.out.println(simpDate.format(date));
The Differences in as easy as much possible: After having a basic understanding, the other comments posted above will be easier to catch.
Shell - "Shell" is a program, which facilitates the interaction between the user and the operating system (kernel). There are many shell implementation available, like sh, bash, csh, zsh...etc.
Using any of the Shell programs, we will be able to execute commands that are supported by that shell program.
Bash - It derived from Bourne-again Shell. Using this program, we will be able to execute all the commands specified by Shell. Also, we will be able to execute some commands that are specifically added to this program. Bash has backward compatibility with sh.
Sh - It derived from Bourne Shell. "sh" supports all the commands specified in the shell. Means, Using this program, we will be able to execute all the commands specified by Shell.
For more information, do: - https://man.cx/sh - https://man.cx/bash
Using bash
:
echo "|${COMMAND/$'\n'}|"
(Note that the control character in this question is a 'newline' (\n
), not a carriage return (\r
); the latter would have output REBOOT|
on a single line.)
Uses the Bash Shell Parameter Expansion ${parameter/pattern/string}
:
The pattern is expanded to produce a pattern just as in filename expansion. Parameter is expanded and the longest match of pattern against its value is replaced with string. [...] If string is null, matches of pattern are deleted and the / following pattern may be omitted.
Also uses the $''
ANSI-C quoting construct to specify a newline as $'\n'
. Using a newline directly would work as well, though less pretty:
echo "|${COMMAND/
}|"
#!/bin/bash
COMMAND="$'\n'REBOOT"
echo "|${COMMAND/$'\n'}|"
# Outputs |REBOOT|
Or, using newlines:
#!/bin/bash
COMMAND="
REBOOT"
echo "|${COMMAND/
}|"
# Outputs |REBOOT|
Here's something I build for this purpose:
focusNextElement: function () {
//add all elements we want to include in our selection
var focussableElements = 'a:not([disabled]), button:not([disabled]), input[type=text]:not([disabled]), [tabindex]:not([disabled]):not([tabindex="-1"])';
if (document.activeElement && document.activeElement.form) {
var focussable = Array.prototype.filter.call(document.activeElement.form.querySelectorAll(focussableElements),
function (element) {
//check for visibility while always include the current activeElement
return element.offsetWidth > 0 || element.offsetHeight > 0 || element === document.activeElement
});
var index = focussable.indexOf(document.activeElement);
if(index > -1) {
var nextElement = focussable[index + 1] || focussable[0];
nextElement.focus();
}
}
}
THis method allows you to have more flexibility of styling your entire content. Effectivly creating two containers that you can style. THe HTML Body tag which serves as your background, and the div with an id of container which contains your content.
This then allows you to position your content within the page, while styling a background or other effects without issue. THink of it as a "Frame" for the content.
If you transferred these files through disk or other means, it is likely they were not saved properly.
C++ (or C for that matter) gives you fine-grained control over your data structures. If you want to bit-twiddle you have that option. Large managed Java or .NET apps (OWB, Visual Studio 2005) that use the internal data structures of the Java/.NET libraries carry the baggage with them. I've seen OWB designer sessions using over 400 MB of RAM and BIDS for cube or ETL design getting into the 100's of MB as well.
On a predictable workload (such as most benchmarks that repeat a process many times) a JIT can get you code that is optimised well enough that there is no practical difference.
IMO on large applications the difference is not so much the JIT as the data structures that the code itself is using. Where an application is memory-heavy you will get less efficient cache usage. Cache misses on modern CPUs are quite expensive. Where C or C++ really win is where you can optimise your usage of data structures to play nicely with the CPU cache.
The function you need is CInt
.
ie CInt(PrinterLabel)
See Type Conversion Functions (Visual Basic) on MSDN
Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!
