Just add a custom property to the page which will return the variable of your choice. You can then use the built-in "control" parameter type.
In the code behind, add:
Dim MyVariable as Long
ReadOnly Property MyCustomProperty As Long
Get
Return MyVariable
End Get
End Property
In the select parameters section add:
<asp:ControlParameter ControlID="__Page" Name="MyParameter"
PropertyName="MyCustomProperty" Type="Int32" />
Using ddl.Items.Clear()
will clear the dropdownlist however you must be sure that your dropdownlist is not set to:
AppendDataBoundItems="True"
This option will cause the rebound data to be appended to the existing list which will NOT be cleared prior to binding.
SOLUTION
Add AppendDataBoundItems="False"
to your dropdownlist.
Now when data is rebound it will automatically clear all existing data beforehand.
Protected Sub ddl1_SelectedIndexChanged(sender As Object, e As EventArgs)
ddl2.DataSource = sql2
ddl2.DataBind()
End Sub
NOTE: This may not be suitable in all situations as appenddatbound items can cause your dropdown to append its own data on each change of the list.
TOP TIP
Still want a default list item adding to your dropdown but need to rebind data?
Use AppendDataBoundItems="False"
to prevent duplication data on postback and then directly after binding your dropdownlist insert a new default list item.
ddl.Items.Insert(0, New ListItem("Select ...", ""))
Declare object of EditText on top of class:
EditText myEditText;
Find EditText in onCreate Function and setOnFocusChangeListener of EditText:
myEditText = findViewById(R.id.yourEditTextNameInxml);
myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean hasFocus) {
if (!hasFocus) {
Toast.makeText(this, "Focus Lose", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(this, "Get Focus", Toast.LENGTH_SHORT).show();
}
}
});
It works fine.
If you are using GWT you will be limited to using java.util.Date, here is a method that takes the date as integers, but still uses java.util.Date:
public int getAge(int year, int month, int day) {
Date now = new Date();
int nowMonth = now.getMonth()+1;
int nowYear = now.getYear()+1900;
int result = nowYear - year;
if (month > nowMonth) {
result--;
}
else if (month == nowMonth) {
int nowDay = now.getDate();
if (day > nowDay) {
result--;
}
}
return result;
}
Jon's answer didn't work for me as I got a compiler error CS0453 C# The type must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method
This worked for me though:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<SomeObject>().HasOptional(m => m.somefield);
base.OnModelCreating(modelBuilder);
}
From the "Zen of Assembly" by Abrash:
LEA
, the only instruction that performs memory addressing calculations but doesn't actually address memory.LEA
accepts a standard memory addressing operand, but does nothing more than store the calculated memory offset in the specified register, which may be any general purpose register.What does that give us? Two things that
ADD
doesn't provide:
- the ability to perform addition with either two or three operands, and
- the ability to store the result in any register; not just one of the source operands.
And LEA
does not alter the flags.
Examples
LEA EAX, [ EAX + EBX + 1234567 ]
calculates EAX + EBX + 1234567
(that's three operands)LEA EAX, [ EBX + ECX ]
calculates EBX + ECX
without overriding either with the result.LEA EAX, [ EBX + N * EBX ]
(N can be 1,2,4,8).Other usecase is handy in loops: the difference between LEA EAX, [ EAX + 1 ]
and INC EAX
is that the latter changes EFLAGS
but the former does not; this preserves CMP
state.
Remove Quote. and use innerText instead of text
function toggleText(button_id)
{ //-----\/ 'button_id' - > button_id
if (document.getElementById(button_id).innerText == "Lock")
{
document.getElementById(button_id).innerText = "Unlock";
}
else
{
document.getElementById(button_id).innerText = "Lock";
}
}
replace
[bash:~] $ sudo update-alternatives --install /usr/bin/python python \
/usr/bin/python2.7 2
[bash:~] $ sudo update-alternatives --install /usr/bin/python python \
/usr/bin/python3.5 3
with
[bash:~] $ sudo update-alternatives --install /usr/local/bin/python python \
/usr/bin/python2.7 2
[bash:~] $ sudo update-alternatives --install /usr/local/bin/python python \
/usr/bin/python3.5 3
e.g. installing into /usr/local/bin
instead of /usr/bin
.
and ensure the /usr/local/bin
is before /usr/bin
in PATH.
i.e.
[bash:~] $ echo $PATH
/usr/local/bin:/usr/bin:/bin
Ensure this always is the case by adding
export PATH=/usr/local/bin:$PATH
to the end of your ~/.bashrc
file. Prefixing the PATH
environment variable with custom bin folder such as /usr/local/bin
or /opt/<some install>/bin
is generally recommended to ensure that customizations are found before the default system ones.
MuSTaNG's answer says it all, but I am still adding it to make it a little more elaborate, with links and all.
The conventional operators
are available for DateTime
since .NET Framework 1.1. Also, addition and subtraction of DateTime
objects are also possible using conventional operators +
and -
.
One example from MSDN:
Equality:System.DateTime april19 = new DateTime(2001, 4, 19);
System.DateTime otherDate = new DateTime(1991, 6, 5);
// areEqual gets false.
bool areEqual = april19 == otherDate;
otherDate = new DateTime(2001, 4, 19);
// areEqual gets true.
areEqual = april19 == otherDate;
Other operators can be used likewise.
Here is the list all operators available for DateTime
.

This should help as well
$(document).on('click', 'someyourContainer .dropdown-menu', function (e) {
e.stopPropagation();
});
For those wanting the box-shadow on the col-*
container itself and not on the .container
, you can add another div
just inside the col-*
element, and add the shadow to that. This element will not have the padding, and therefor not interfere.
The first image has the box-shadow
on the col-*
element. Because of the 15px padding on the col
element, the shadow is pushed to the outside of the div
element rather than on the visual edges of it.
<div class="col-md-4" style="box-shadow: 0px 2px 25px rgba(0, 0, 0, .25);">
<div class="thumbnail">
{!! HTML::image('images/sampleImage.png') !!}
</div>
</div>
The second image has a wrapper div
with the box-shadow
on it. This will place the box-shadow
on the visual edges of the element.
<div class="col-md-4">
<div id="wrapper-div" style="box-shadow: 0px 2px 25px rgba(0, 0, 0, .25);">
<div class="thumbnail">
{!! HTML::image('images/sampleImage.png') !!}
</div>

There are a lot of sources for selenium - here is good one for simple use Selenium, and here is a example snippet too Selenium Examples
You can find a lot of good sources to use selenium, it's not too hard to get it set up and start using it.
You can try this. :) simple solution!
=IF(ISNUMBER(MATCH(I1,E:E,0)),"TRUE","")
The array you created by Dim s(0) As String
IS NOT EMPTY
In VB.Net, the subscript you use in the array is index of the last element. VB.Net by default starts indexing at 0, so you have an array that already has one element.
You should instead try using System.Collections.Specialized.StringCollection
or (even better) System.Collections.Generic.List(Of String)
. They amount to pretty much the same thing as an array of string, except they're loads better for adding and removing items. And let's be honest: you'll rarely create an empty string array without wanting to add at least one element to it.
If you really want an empty string array, declare it like this:
Dim s As String()
or
Dim t() As String
Yes that is valid syntax but it may well not do what you want.
Execution will continue after your RAISERROR
except if you add a RETURN
. So you will need to add a block with BEGIN ... END
to hold the two statements.
Also I'm not sure why you plumped for severity 15. That usually indicates a syntax error.
Finally I'd simplify the conditions using IN
CREATE PROCEDURE [dbo].[AddApplicationUser] (@TenantId BIGINT,
@UserType TINYINT,
@UserName NVARCHAR(100),
@Password NVARCHAR(100))
AS
BEGIN
IF ( @TenantId IS NULL
AND @UserType IN ( 0, 1 ) )
BEGIN
RAISERROR('The value for @TenantID should not be null',15,1);
RETURN;
END
END
Use the built in function zip

Just looking at the new features of 2.7. There is now a function in the itertools module which is similar to the above code.

itertools.compress('ABCDEF', [1,0,1,0,1,1]) =>
A, C, E, F
An alternative to MERGE (the "old fashioned way"):
begin
insert into t (mykey, mystuff)
values ('X', 123);
exception
when dup_val_on_index then
update t
set mystuff = 123
where mykey = 'X';
end;
In Stored Procedures statements are written only once and reduces network traffic between clients and servers. We can also avoid Sql Injection Attacks.
You may want to try changing the environment variable "PYTHONIOENCODING" to "utf_8". I have written a page on my ordeal with this problem.
Tl;dr of the blog post:
import sys, locale, os
print(sys.stdout.encoding)
print(sys.stdout.isatty())
print(locale.getpreferredencoding())
print(sys.getfilesystemencoding())
print(os.environ["PYTHONIOENCODING"])
print(chr(246), chr(9786), chr(9787))
gives you
utf_8
False
ANSI_X3.4-1968
ascii
utf_8

I thought about adding something new to this answer, so I don't feel as bad... Here is a Swift answer:
import Cocoa
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.lineSpacing = 40
let attrString = NSMutableAttributedString(string: "Swift Answer")
attrString.addAttribute(.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attrString.length))
var tableViewCell = NSTableCellView()
tableViewCell.textField.attributedStringValue = attrString
"Short answer: you can't. To change the spacing between lines of text, you will have to subclass UILabel and roll your own drawTextInRect, or create multiple labels."
This is a really old answer, and other have already addded the new and better way to handle this.. Please see the up to date answers provided below.
Use ROUND
but with num_digits
= -1
=ROUND(A1,-1)
Also applies to ROUNDUP
and ROUNDDOWN
From Excel help:
EDIT:
To get the numbers to always round up use =ROUNDUP(A1,-1)
You can use this code(Recommended)
MemoryStream objMS = new MemoryStream();
DataTable oDT = new DataTable();//Your DataTable which you want to convert
oDT.WriteXml(objMS);
objMS.Position = 0;
XPathDocument result = new XPathDocument(objMS);
This is another way but first ex. is recommended
StringWriter objSW = new StringWriter();
DataTable oDt = new DataTable();//Your DataTable which you want to convert
oDt.WriteXml(objSW);
string result = objSW.ToString();
Another way that could be used in some situations is to set the link color in the properties of the view that is taking the Spannable.
If your Spannable is going to be used in a TextView, for example, you can set the link color in the XML like this:
<TextView
android:id="@+id/myTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColorLink="@color/your_color"
</TextView>
You can also set it in the code with:
TextView tv = (TextView) findViewById(R.id.myTextView);
tv.setLinkTextColor(your_color);
You can use Perl style regular expressions as well. A digit is just \d
then.
grep -Po "\\d+" filename
-P Interpret PATTERNS as Perl-compatible regular expressions (PCREs).
-o Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.
SQL Developer 4.1, released in May of 2015, added a Model tab which shows table foreign keys which refer to your table in an Entity Relationship Diagram format.
Here it is: http://jsfiddle.net/tQyvp/
Here's the code if you don't like going to jsfiddle:
html
<input id="myinputfield" value="This is some text" type="button">?
Javascript:
$('body').on('click', '#myinputfield', function(){
var textField = $('#myinputfield');
textField.val(textField.val()+' after clicking')
});?
You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):
dataGridView1.Columns[1].Width = 108; // or whatever width works well for abbrev
dataGridView1.Columns[2].Width =
dataGridView1.Width
- dataGridView1.Columns[0].Width
- dataGridView1.Columns[1].Width
- 72; // this is an extra "margin" number of pixels
If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize
event handler of the DataGridView.
It's quite simple, use
Long.valueOf(String s);
For example:
String s;
long l;
Scanner sc=new Scanner(System.in);
s=sc.next();
l=Long.valueOf(s);
System.out.print(l);
You're done!!!
in devices which has Android 4.3 and above you should follow these steps:
How to enable Developer Options:
Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.
In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.
add \ before special characters:
s/\?page=one&/page\/one\//g
etc.
Based on some (minimal) benchmarks using the timeit
module it seems that the following has similar if not better performance than the accepted answer
new_lst = [a, *lst]
As with [a] + list
this will create a new list and not mutate lst
.
If your intention is to mutate the list then use lst.insert(0, a)
.
Reselecting key file in a combobox and entering password helps on this for us.

If You want make json object from yor model do like this :
foreach (var item in Persons)
{
var jsonObj=["FirstName":"@item.FirstName"]
}
Or Use Json.Net to make json from your model :
string json = JsonConvert.SerializeObject(person);
The extension of the file does not matter to most C compilers, so it will work.
However, depending on your makefile or project settings the included c file might generate a separate object file. When linking that might lead to double defined symbols.
Path.GetDirectoryName(Context.Parameters["assemblypath"])
I think I would use eval()
, but would first check to make sure the string is a valid mathematical expression, as opposed to something malicious. You could use a regex for the validation.
eval()
also takes additional arguments which you can use to restrict the namespace it operates in for greater security.
Using Linux Top
command
top -H -p (process id)
you could get process id of one program by this method :
ps aux | grep (your program name)
for example :
ps aux | grep user.py

Others here have given quite elaborate code for this. Perhaps more elaborate code was needed at that time, I don't know. Anyway, I upvoted one of them, but here is a very much simplified version that works the same:

document.getElementById('inp').click();
}
function readFile(e) {
var file = e.target.files[0];
if (!file) return;
var reader = new FileReader();
reader.onload = function(e) {
document.getElementById('contents').innerHTML = e.target.result;
}
reader.readAsText(file)
}

Remove static
keyword in method definition. Keep it just in your class definition.
static
keyword placed in .cpp file means that a certain function has a static linkage, ie. it is accessible only from other functions in the same file.
Simple example of how to use it
<?php
if(!isset($_POST) || empty($_POST)) {
?>
<form name="form1" method="post" action="">
<input type="text" name="textfield"><br />
<input type="submit" name="Submit" value="submit">
</form>
<?php
} else {
$example = file_get_contents("php://input");
echo $example; }
?>
This solution works in Windows 7 using Workbench. You will need Administrator privileges to do this. It creates a junction (like a shortcut) to wherever you really want to store your data
Open Workbench and select INSTANCE - Startup / Shutdown Stop the server
Install Junction Master from https://bitsum.com/junctionmaster.php
Navigate to C:\ProgramData\MySQL\MySQL Server 5.6
Right click on Data and select "MOVE and then LINK folder to ..." Accept the warning Point destination to "Your new data directory here without the quotes" Click MOVE AND LINK
Now go to "Your new data directory here without the quotes"
Right click on Data Go to the security tab Click Edit Click Add Type NETWORK SERVICE then Check Names Click OK Click the Allow Full Control checkbox and then OK
Go back to Workbench and Start the server
This method worked for me using MySQL Workbench 6.2 on Windows 7 Enterprise.
All the model fields which have definite types, those should be validated when returned to Controller. If any of the model fields are not matching with their defined type, then ModelState.IsValid will return false. Because, These errors will be added in ModelState.
Converting the date without specifying the current format can bring this error to you easily.
sdate <- "2015.10.10"
date <- as.Date(sdate4) # ==> This will generate the same error"""Error in charToDate(x): character string is not in a standard unambiguous format""".
date <- as.Date(sdate4, format = "%Y.%m.%d") # ==> Error Free Date Conversion.
You can use getAllThreadIds that Returns all live thread IDs. Some threads included in the returned array may have been terminated when this method returns.
ManagementFactory.getThreadMXBean().getAllThreadIds()
If you only want to return a blank when B2 is blank you can use an additional IF function for that scenario specifically, i.e.
=IF(B2="","",VLOOKUP(B2,Index!A1:B12,2,FALSE))
or to return a blank with any error from the VLOOKUP (e.g. including if B2 is populated but that value isn't found by the VLOOKUP) you can use IFERROR function if you have Excel 2007 or later, i.e.
=IFERROR(VLOOKUP(B2,Index!A1:B12,2,FALSE),"")
in earlier versions you need to repeat the VLOOKUP, e.g.
=IF(ISNA(VLOOKUP(B2,Index!A1:B12,2,FALSE)),"",VLOOKUP(B2,Index!A1:B12,2,FALSE))

All the below answers would return you the list.Your need to convert it to matrix
def MATMUL(X, Y):
rows_A = len(X)
cols_A = len(X[0])
rows_B = len(Y)
cols_B = len(Y[0])
if cols_A != rows_B:
print "Matrices are not compatible to Multiply. Check condition C1==R2"
return
# Create the result matrix
# Dimensions would be rows_A x cols_B
C = [[0 for row in range(cols_B)] for col in range(rows_A)]
print C
for i in range(rows_A):
for j in range(cols_B):
for k in range(cols_A):
C[i][j] += A[i][k] * B[k][j]
C = numpy.matrix(C).reshape(len(A),len(B[0]))
return C
Code will be as below:
public class A{
public static void main(String args[]){
String str="hello";
for(int i=str.length()-1;i>=0;i--){
String str1=str.charAt(i);
system.out.print(str1);
}
}
}
The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.
When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.
The correct answer is: There is no such thing as kernel space and user space. The processor instruction set has special permissions to set destructive things like the root of the page table map, or access hardware device memory, etc.
Kernel code has the highest level privileges, and user code the lowest. This prevents user code from crashing the system, modifying other programs, etc.
Generally kernel code is kept under a different memory map than user code (just as user spaces are kept in different memory maps than each other). This is where the "kernel space" and "user space" terms come from. But that is not a hard and fast rule. For example, since the x86 indirectly requires its interrupt/trap handlers to be mapped at all times, part (or some OSes all) of the kernel must be mapped into user space. Again, this does not mean that such code has user privileges.
Why is the kernel/user divide necessary? Some designers disagree that it is, in fact, necessary. Microkernel architecture is based on the idea that the highest privileged sections of code should be as small as possible, with all significant operations done in user privileged code. You would need to study why this might be a good idea, it is not a simple concept (and is famous for both having advantages and drawbacks).

Avoid raw types
Raw types refer to using a generic type without specifying a type parameter.
For example,
A list is a raw type, while List<String>
is a parameterized type.
When generics were introduced in JDK 1.5, raw types were retained only to maintain backwards compatibility with older versions of Java. Although using raw types is still possible,
They should be avoided:
They are less expressive, and don't self-document in the same way as parameterized types Example
import java.util.*;
public final class AvoidRawTypes {
void withRawType() {
//Raw List doesn't self-document,
//doesn't state explicitly what it can contain
List stars = Arrays.asList("Arcturus", "Vega", "Altair");
Iterator iter = stars.iterator();
while (iter.hasNext()) {
String star = (String) iter.next(); //cast needed
log(star);
}
}
void withParameterizedType() {
List < String > stars = Arrays.asList("Spica", "Regulus", "Antares");
for (String star: stars) {
log(star);
}
}
private void log(Object message) {
System.out.println(Objects.toString(message));
}
}
For reference: https://docs.oracle.com/javase/tutorial/java/generics/rawTypes.html

The other answers so far have a lot of technical information. I will try to answer, as requested, in simple terms.
Serialization is what you do to an instance of an object if you want to dump it to a raw buffer, save it to disk, transport it in a binary stream (e.g., sending an object over a network socket), or otherwise create a serialized binary representation of an object. (For more info on serialization see Java Serialization on Wikipedia).
If you have no intention of serializing your class, you can add the annotation just above your class @SuppressWarnings("serial")
.
If you are going to serialize, then you have a host of things to worry about all centered around the proper use of UUID. Basically, the UUID is a way to "version" an object you would serialize so that whatever process is de-serializing knows that it's de-serializing properly. I would look at Ensure proper version control for serialized objects for more information.
A)
Object* o;
o = new Object();
`` B)
Object* o = new Object();
I think A and B has no difference. In both the cases o is a pointer to class Object. statement new Object() creates an object of class Object from heap memory. Assignment statement assigns the address of allocated memory to pointer o.
One thing I would like to mention that size of allocated memory from heap is always the sizeof(Object) not sizeof(Object) + sizeof(void *).
element.innerHTML = ""
(or .textContent) is by far the fastest solution
For example:
https://jsperf.com/innerhtml-vs-removechild/15
This test does not add new children to the element between each iteration. The first iteration will remove the element's contents, and every other iteration will then do nothing.
In this case, while (box.lastChild) box.removeChild(box.lastChild)
was faster because box.lastChild was null
99% of the time
Here is a proper test: https://jsperf.com/innerhtml-conspiracy
Finally, do not use node.parentNode.replaceChild(node.cloneNode(false), node)
. This will replace the node with a copy of itself without its children. However, this does not preserve event listeners and breaks any other references to the node.
If you're supporting API 11 or higher, you can just use the following XML attribute:
android:rotation="90"
It might not display correctly in Android Studio xml preview, but it works as expected.
I know it's a little off-topic, but following up with the solution presented by Jonas Bøhmer, actually I think that MOD is the best solution to your example.
If your intention was to limit the result to one digit, MOD is the best approach to achieve it.
ie. Let's suppose that VLOOKUP(A1, B:B, 1, 0) returns 23. Your IF formula would simply make this calculation: 23 - 10 and return 13 as the result.
On the other hand, MOD(VLOOKUP(A1, B:B, 1, 0), 10) would divide 23 by 10 and show the remainder: 3.
Back to the main topic, when I need to use a formula that repeats some part, I usually put it on another cell and then hide it as some people already suggested.
Java 8 supports default methods in interfaces. And in JDK 8 a lot of old interfaces now have new default methods. For example, now in CharSequence we have chars and codePoints methods.
If source level of your project is lower than 1.8, then compiler doesn't allow you to use default methods in interfaces. So it cannot compile classes that directly on indirectly depend on this interfaces.
If I get your problem right, then you have two solutions. First solution is to rollback to JDK 7, then you will use old CharSequence interface without default methods. Second solution is to set source level of your project to 1.8, then your compiler will not complain about default methods in interfaces.
Read /usr/src/linux/Documentation/sysctl/kernel.txt.
[/proc/sys/kernel/]core_pattern is used to specify a core dumpfile pattern name.
- If the first character of the pattern is a '|', the kernel will treat the rest of the pattern as a command to run. The core dump will be written to the standard input of that program instead of to a file.
Instead of writing the core dump to disk, your system is configured to send it to the abrt
program instead. Automated Bug Reporting Tool is possibly not as documented as it should be...
In any case, the quick answer is that you should be able to find your core file in /var/cache/abrt
, where abrt
stores it after being invoked. Similarly, other systems using Apport may squirrel away cores in /var/crash
, and so on.

Using bash string manipulation http://www.tldp.org/LDP/abs/html/string-manipulation.html

I found http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2005-11/0118.html. But it's ugly as hell...
My 2¢! Really, part of the reason I'm throwing this up here, despite the long list of answers, is to provide a little more all in one
type solution and get some feed back in the future on how to expand it to include more real types
.
With the following solution, as aforementioned, I combined a couple of solutions found here, as well as incorporate a fix for returning a value of jQuery on jQuery defined object if available. I also append the method to the native Object prototype. I know that is often taboo, as it could interfere with other such extensions, but I leave that to user beware
. If you don't like this way of doing it, simply copy the base function anywhere you like and replace all variables of this
with an argument parameter to pass in (such as arguments[0]).
;(function() { // Object.realType
function realType(toLower) {
var r = typeof this;
try {
if (window.hasOwnProperty('jQuery') && this.constructor && this.constructor == jQuery) r = 'jQuery';
else r = this.constructor && this.constructor.name ? this.constructor.name : Object.prototype.toString.call(this).slice(8, -1);
}
catch(e) { if (this['toString']) r = this.toString().slice(8, -1); }
return !toLower ? r : r.toLowerCase();
}
Object['defineProperty'] && !Object.prototype.hasOwnProperty('realType')
? Object.defineProperty(Object.prototype, 'realType', { value: realType }) : Object.prototype['realType'] = realType;
})();
Then simply use with ease, like so:
obj.realType() // would return 'Object'
obj.realType(true) // would return 'object'
Note: There is 1 argument passable. If is bool of
true
, then the return will always be in lowercase.
More Examples:
true.realType(); // "Boolean"
var a = 4; a.realType(); // "Number"
$('div:first').realType(); // "jQuery"
document.createElement('div').realType() // "HTMLDivElement"
If you have anything to add that maybe helpful, such as defining when an object was created with another library (Moo, Proto, Yui, Dojo, etc...) please feel free to comment or edit this and keep it going to be more accurate and precise. OR roll on over to the GitHub I made for it and let me know. You'll also find a quick link to a cdn min file there.

This will work for general reading a String

If you would like to read longer text (large size of text), then use the method that other people here were mentioned such as buffered (reserve the size of the text in memory space).
NSString* filePath = @""//file path...
NSString* fileRoot = [[NSBundle mainBundle]
pathForResource:filePath ofType:@"txt"];
// read everything from text
NSString* fileContents =
[NSString stringWithContentsOfFile:fileRoot
encoding:NSUTF8StringEncoding error:nil];
// first, separate by new line
NSArray* allLinedStrings =
[fileContents componentsSeparatedByCharactersInSet:
[NSCharacterSet newlineCharacterSet]];
// then break down even further
NSString* strsInOneLine =
[allLinedStrings objectAtIndex:0];
// choose whatever input identity you have decided. in this case ;
NSArray* singleStrs =
[currentPointString componentsSeparatedByCharactersInSet:

There you have it.

For SQL Server, if using a newer version, you can use
select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='tableName'
There are different ways to get the schema. Using ADO.NET, you can use the schema methods. Use the DbConnection
's GetSchema
method or the DataReader
'sGetSchemaTable
method.
Provided that you have a reader for the for the query, you can do something like this:
using(DbCommand cmd = ...)
using(var reader = cmd.ExecuteReader())
{
var schema = reader.GetSchemaTable();
foreach(DataRow row in schema.Rows)
{
Debug.WriteLine(row["ColumnName"] + " - " + row["DataTypeName"])
}
}

Try using open()/write()/close() API calls and experiment with the output buffer size. I mean do not pass the whole "many-many-bytes" buffer at once, do a couple of writes (i.e., TotalNumBytes / OutBufferSize). OutBufferSize can be from 4096 bytes to megabyte.
Another try - use WinAPI OpenFile/CreateFile and use this MSDN article to turn off buffering (FILE_FLAG_NO_BUFFERING). And this MSDN article on WriteFile() shows how to get the block size for the drive to know the optimal buffer size.
Anyway, std::ofstream is a wrapper and there might be blocking on I/O operations. Keep in mind that traversing the entire N-gigabyte array also takes some time. While you are writing a small buffer, it gets to the cache and works faster.
Much has changed with hooks, e.g. componentWillReceiveProps
turned into useEffect
+useRef
(as shown in this other SO answer), but Props are still Read-Only, so only the caller method should update it.
The JDK does not install a JVM in the default path.
Unless you need external tools to run like ant, the non-JDK is enough for Eclipse to run. The easiest way to install such a JVM is to go to http://java.com and let it install whatever it want to install.
Then double-click the Eclipse binary again.
To add ANDROID_HOME value permanently,
gedit ~/.bashrc
and add the following lines
export ANDROID_HOME=/root/Android/Sdk

Save the file and you need not update ANDROID_HOME value everytime.
While CMS is correct that passing strings into the parse method is generally unsafe, the new ECMA-262 5th Edition (aka ES5) specification in section 15.9.4.2 suggests that Date.parse()
actually should handle ISO-formatted dates. The old specification made no such claim. Of course, old browsers and some current browsers still do not provide this ES5 functionality.
Your second example isn't wrong. It is the specified date in UTC, as implied by Date.prototype.toISOString()
, but is represented in your local timezone.

What you're talking about is becoming a payment service provider. I have been there and done that. It was a lot easier about 10 years ago than it is now, but if you have a phenomenal amount of time, money and patience available, it is still possible.
You will need to contact an acquiring bank. You didnt say what region of the world you are in, but by this I dont mean a local bank branch. Each major bank will generally have a separate card acquiring arm. So here in the UK we have (eg) Natwest bank, which uses Streamline (or Worldpay) as its acquiring arm. In total even though we have scores of major banks, they all end up using one of five or so card acquirers.
Happily, all UK card acquirers use a standard protocol for communication of authorisation requests, and end of day settlement. You will find minor quirks where some acquiring banks support some features and have slightly different syntax, but the differences are fairly minor. The UK standards are published by the Association for Payment Clearing Services (APACS) (which is now known as the UKPA). The standards are still commonly referred to as APACS 30 (authorization) and APACS 29 (settlement), but are now formally known as APACS 70 (books 1 through 7).
Although the APACS standard is widely supported across the UK (Amex and Discover accept messages in this format too) it is not used in other countries - each country has it's own - for example: Carte Bancaire in France, CartaSi in Italy, Sistema 4B in Spain, Dankort in Denmark etc. An effort is under way to unify the protocols across Europe - see EPAS.org
Communicating with the acquiring bank can be done a number of ways. Again though, it will depend on your region. In the UK (and most of Europe) we have one communications gateway that provides connectivity to all the major acquirers, they are called TNS and there are dozens of ways of communicating through them to the acquiring bank, from dialup 9600 baud modems, ISDN, HTTPS, VPN or dedicated line. Ultimately the authorisation request will be converted to X25 protocol, which is the protocol used by these acquiring banks when communicating with each other.
In summary then: it all depends on your region.
Once you are registered and accredited you'll then be able to accept customers and set up merchant accounts on behalf of the bank/s you're accredited against (bearing in mind that each acquirer will generally support multiple banks). Rinse and repeat with other acquirers as you see necessary.
Beyond that you have lots of other issues, mainly dealing with PCI-DSS. Thats a whole other topic and there are already some q&a's on this site regarding that. Like I say, its a phenomenal undertaking - most likely a multi-year project even for a reasonably sized team, but its certainly possible.
$protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https'?'https':'http';

These should both work
HashMap<String, ArrayList<Item>> items = new HashMap<String, ArrayList<Item>>();
public synchronized void addToList(String mapKey, Item myItem) {
List<Item> itemsList = items.get(mapKey);
// if list does not exist create it
if(itemsList == null) {
itemsList = new ArrayList<Item>();
itemsList.add(myItem);
items.put(mapKey, itemsList);
} else {
// add if item is not already in list
if(!itemsList.contains(myItem)) itemsList.add(myItem);
}
}
I know its already accepted, but for thoses like me who look for "remove ALL whitespaces" (not just at the begining and endingof the string):
select SUBSTRING_INDEX('1234 243', ' ', 1);
// returns '1234'
EDIT 2019/6/20 : Yeah, that's not good. The function returns the part of the string since "when the character space occured for the first time". So, I guess that saying this remove the leading and trailling whitespaces and returns the first word :
select SUBSTRING_INDEX(TRIM(' 1234 243'), ' ', 1);
First of all, be sure that you have downloaded it or not. Open up your terminal application, and enter $ gcc
if you have not installed it you will get an alert. You can verify that you have installed it by
$ xcode-select -p
/Library/Developer/CommandLineTools
And to be sure then enter $ gcc --version
You can read more about the process here: Xcode command line tools for Mavericks
From the CLI the best way is to use grep
like:
php -i | grep libxml
(MyColours)Enum.Parse(typeof(MyColours), "red", true); // MyColours.Red
(int)((MyColours)Enum.Parse(typeof(MyColours), "red", true)); // 0
How to reproduce this error in PHP:
Create an empty array and ask for the value given a key like this:
php> $foobar = array();
php> echo gettype($foobar);
array
php> echo $foobar[0];
PHP Notice: Undefined offset: 0 in
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(578) :
eval()'d code on line 1
What happened?
You asked an array to give you the value given a key that it does not contain. It will give you the value NULL then put the above error in the errorlog.
It looked for your key in the array, and found undefined
.
How to make the error not happen?
Ask if the key exists first before you go asking for its value.
php> echo array_key_exists(0, $foobar) == false;
1
If the key exists, then get the value, if it doesn't exist, no need to query for its value.
In C99(ISO/IEC 9899:TC3)
which seems absent from this discussion thus far the following steteents are made regarding order of evaluaiton.
[...]the order of evaluation of subexpressions and the order in which side effects take place are both unspecified. (Section 6.5 pp 67)
The order of evaluation of the operands is unspecified. If an attempt is made to modify the result of an assignment operator or to access it after the next sequence point, the behavior[sic] is undefined.(Section 6.5.16 pp 91)
I see the most voted answer doesn't solve this question, which is in the context of rebasing.
The only way to synchronize the two diverged branches is to merge them back together, resulting in an extra merge commit and two sets of commits that contain the same changes (the original ones, and the ones from your rebased branch). Needless to say, this is a very confusing situation.
So, before you run git rebase
, always ask yourself, “Is anyone else looking at this branch?” If the answer is yes, take your hands off the keyboard and start thinking about a non-destructive way to make your changes (e.g., the git revert
command). Otherwise, you’re safe to re-write history as much as you like.

Okay I had the same issue and solved it. For some reason the mysql_secure_installation script doesn't work out of the box when using Homebrew to install mysql, so I did it manually. On the CLI enter:
mysql -u root
That should get you into mysql. Now do the following (taken from mysql_secure_installation):
UPDATE mysql.user SET Password=PASSWORD('your_new_pass') WHERE User='root';
DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');
DELETE FROM mysql.user WHERE User='';
DELETE FROM mysql.db WHERE Db='test' OR Db='test\\_%'
DROP DATABASE test;
FLUSH PRIVILEGES;
Now exit and get back into mysql with: mysql -u root -p
If you are on a 64bit build of ubuntu or debian (see e.g. 'cat /proc/version') you should simply use the 64bit cross compilers, if you cloned
git clone https://github.com/raspberrypi/tools
then the 64bit tools are in
tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64
use that directory for the gcc-toolchain. A useful tutorial for compiling that I followed is available here Building and compiling Raspberry PI Kernel (use the -x64 path from above as ${CCPREFIX})
I think all you need to display the data on an HTML page is JSON.stringify
.
For example, if your JSON is stored like this:
var jsonVar = {
text: "example",
number: 1
};
Then you need only do this to convert it to a string:
var jsonStr = JSON.stringify(jsonVar);
And then you can insert into your HTML directly, for example:
document.body.innerHTML = jsonStr;
Of course you will probably want to replace body
with some other element via getElementById
.
As for the CSS part of your question, you could use RegExp to manipulate the stringified object before you put it into the DOM. For example, this code (also on JSFiddle for demonstration purposes) should take care of indenting of curly braces.
var jsonVar = {
text: "example",
number: 1,
obj: {
"more text": "another example"
},
obj2: {
"yet more text": "yet another example"
}
}, // THE RAW OBJECT
jsonStr = JSON.stringify(jsonVar), // THE OBJECT STRINGIFIED
regeStr = '', // A EMPTY STRING TO EVENTUALLY HOLD THE FORMATTED STRINGIFIED OBJECT
f = {
brace: 0
}; // AN OBJECT FOR TRACKING INCREMENTS/DECREMENTS,
// IN PARTICULAR CURLY BRACES (OTHER PROPERTIES COULD BE ADDED)
regeStr = jsonStr.replace(/({|}[,]*|[^{}:]+:[^{}:,]*[,{]*)/g, function (m, p1) {
var rtnFn = function() {
return '<div style="text-indent: ' + (f['brace'] * 20) + 'px;">' + p1 + '</div>';
},
rtnStr = 0;

This code simply looks for sections of the object within the string and separates them into divs (though you could change the HTML part of that). Every time it encounters a curly brace, however, it increments or decrements the indentation depending on whether it's an opening brace or a closing (behaviour similar to the space argument of 'JSON.stringify'). But you could this as a basis for different types of formatting.
My variant on printing the parent process:
ps -p $$ | awk '$1 == PP {print $4}' PP=$$
Don't run unnecessary applications when AWK can do it for you.
I discovered the following, which prints out which lines, if any, have null characters:
perl -ne '/\000/ and print;' file-with-nulls
Also, an octal dump can tell you if there are nulls:
od file-with-nulls | grep ' 000'

Did you try showing your window using the ShowDialog method?
Don't forget to set the Owner property on the dialog window to the main window. This will avoid weird behavior when Alt+Tabbing, etc.
Here 2 ways to do it:
set.seed(1)
tt <- sample(letters,100,rep=TRUE)
## using table
table(tt)
tt
a b c d e f g h i j k l m n o p q r s t u v w x y z
2 3 3 3 2 4 6 1 6 5 6 4 7 2 2 2 5 4 5 3 8 4 5 4 3 1
## using tapply
tapply(tt,tt,length)
a b c d e f g h i j k l m n o p q r s t u v w x y z
2 3 3 3 2 4 6 1 6 5 6 4 7 2 2 2 5 4 5 3 8 4 5 4 3 1
If we do it just like this:
Dim myArr as Variant
myArr = Range("A1:A10")
the new array will be with two dimensions. Which is not always somehow comfortable to work with:
To get away of the two dimensions, when getting a single column to array, we may use the built-in Excel function “Transpose”. With it, the data becomes in one dimension:
If we have the data in a row, a single transpose will not do the job. We need to use the Transpose function twice:
Note: As you see from the screenshots, when generated this way, arrays start with 1, not with 0. Just be a bit careful.
My Java version was the 1.6 and I found that was using 1.7 with CDI however after that I changed the Java version to 1.7 and import the package javax.faces.bean.ManagedBean and everything worked.

At first glance one really wants to use New-PSDrive
supplying it credentials.
> New-PSDrive -Name P -PSProvider FileSystem -Root \\server\share -Credential domain\user
New-PSDrive : Cannot retrieve the dynamic parameters for the cmdlet. Dynamic parameters for NewDrive cannot be retrieved for the 'FileSystem' provider. The provider does not support the use of credentials. Please perform the operation again without specifying credentials.
The documentation states that you can provide a PSCredential
object but if you look closer the cmdlet does not support this yet. Maybe in the next version I guess.
Therefore you can either use net use
or the WScript.Network
object, calling the MapNetworkDrive
function:
$net = new-object -ComObject WScript.Network
$net.MapNetworkDrive("u:", "\\server\share", $false, "domain\user", "password")
Apparently with newer versions of PowerShell, the New-PSDrive
cmdlet works to map network shares with credentials!
New-PSDrive -Name P -PSProvider FileSystem -Root \\Server01\Public -Credential user\domain -Persist
The (^) XOR operator generates 1 when it is applied on two different bits (0 and 1). It generates 0 when it is applied on two same bits (0 and 0 or 1 and 1).
Ran into this exact problem.
What I ended up doing:
# starting with date string
sdt = "20190901"
std_format = '%Y%m%d'
# create naive datetime object
from datetime import datetime
dt = datetime.strptime(sdt, sdt_format)
# extract the relevant date time items
dt_formatters = ['%Y','%m','%d']
dt_vals = tuple(map(lambda formatter: int(datetime.strftime(dt,formatter)), dt_formatters))
# set timezone
import pendulum
tz = pendulum.timezone('utc')
dt_tz = datetime(*dt_vals,tzinfo=tz)
If you have downloaded Github Desktop Client 1.0.9

Just add the attribute disabled
to the element (or use jQuery to do it for you). Disabled prevents the input from being focused or selected at all.
indeed, all of these datetime types can be difficult, and potentially problematic (must keep careful track of timezone information). here's what i have done, though i admit that i am concerned that at least part of it is "not by design". also, this can be made a bit more compact as needed. starting with a numpy.datetime64 dt_a:
dt_a
numpy.datetime64('2015-04-24T23:11:26.270000-0700')
dt_a1 = dt_a.tolist() # yields a datetime object in UTC, but without tzinfo
dt_a1
datetime.datetime(2015, 4, 25, 6, 11, 26, 270000)
# now, make your "aware" datetime:
dt_a2=datetime.datetime(*list(dt_a1.timetuple()[:6]) + [dt_a1.microsecond], tzinfo=pytz.timezone('UTC'))
... and of course, that can be compressed into one line as needed.
Use localStorage to store the fact that you opened the page :
$(document).ready(function() {
var yetVisited = localStorage['visited'];
if (!yetVisited) {
// open popup
localStorage['visited'] = "yes";
}
});
There is no way for the system to tell you if a String
represent a file
or directory
, if it does not exist in the file system. For example:
Path path = Paths.get("/some/path/to/dir");
System.out.println(Files.isDirectory(path)); // return false
System.out.println(Files.isRegularFile(path)); // return false
And for the following example:
Path path = Paths.get("/some/path/to/dir/file.txt");
System.out.println(Files.isDirectory(path)); //return false
System.out.println(Files.isRegularFile(path)); // return false
So we see that in both case system return false. This is true for both java.io.File
and java.nio.file.Path
GetAwaiter()
, that is used by await
, is implemented as an extension method in the Async CTP. I'm not sure what exactly are you using (you mention both the Async CTP and VS 2012 RC in your question), but it's possible the Async targeting pack uses the same technique.
The problem then is that extension methods don't work with dynamic
. What you can do is to explicitly specify that you're working with a Task
, which means the extension method will work, and then switch back to dynamic
:
private async void MyButtonClick(object sender, RoutedEventArgs e)
{
dynamic request = new SerializableDynamicObject();
request.Operation = "test";
Task<SerializableDynamicObject> task = Client(request);
dynamic result = await task;
// use result here
}
Or, since the Client()
method is actually not dynamic, you could call it with SerializableDynamicObject
, not dynamic
, and so limit using dynamic
as much as possible:
private async void MyButtonClick(object sender, RoutedEventArgs e)
{
var request = new SerializableDynamicObject();
dynamic dynamicRequest = request;
dynamicRequest.Operation = "test";
var task = Client(request);
dynamic result = await task;
// use result here
}

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.
Discord supports Markdown and uses highlight.js to highlight code-blocks.
Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.
To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).
```language
message
```
Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).
Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

No import is necessary as long as you declare both a.go

to be in the same package. Then, you can use go run
to recognize multiple files with:
$ go run a.go b.go
A simpler version of your code would be:
dict(zip(names, d.values()))
If you want to keep the same structure, you can change it to:
vlst = list(d.values())
{names[i]: vlst[i] for i in range(len(names))}
(You can just as easily put list(d.values())
inside the comprehension instead of vlst
; it's just wasteful to do so since it would be re-generating the list every time).

Have you tried:
SELECT Cast( 2.555 as decimal(53,8))
This would return 2.55500000
. Is that what you want?
UPDATE:
Apparently you can also use SQL_VARIANT_PROPERTY to find the precision and scale of a value. Example:
SELECT SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Precision'),
SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Scale')
returns 8|7
You may be able to use this in your conversion process...
Use for of loop instead which is part of ES2015 release. Unlike forEach, we can use return, break and continue. See https://hacks.mozilla.org/2015/04/es6-in-depth-iterators-and-the-for-of-loop/

This option was introduced in order to remove the need to deploy very large PIAs (Primary Interop Assemblies) for interop.
It simply embeds the managed bridging code used that allows you to talk to unmanaged assemblies, but instead of embedding it all it only creates the stuff you actually use in code.
Read more in Scott Hanselman's blog post about it and other VS improvements here.
As for whether it is advised or not, I'm not sure as I don't need to use this feature. A quick web search yields a few leads:
The only risk of turning them all to false is more deployment concerns with PIA files and a larger deployment if some of those files are large.
You can change the port while you open your XAMP control panel, follow the steps:
httpd.conf
, a text file will openlisten:80

replace with listen:8080
andOnce done that, you will be able to start your local server.
You can try the enable/disable methods instead of using the option method:
$("#txtSearch").datepicker("enable");
$("#txtSearch").datepicker("disable");
This disables the entire textbox. So may be you can use datepicker.destroy()
instead:
$(document).ready(function() {
$("#ddlSearchType").change(function() {
if ($(this).val() == "Required Date" || $(this).val() == "Submitted Date") {
$("#txtSearch").datepicker();
}
else {
$("#txtSearch").datepicker("destroy");
}
}).change();
});
Here is a pure Java
solution actually:
public static long getFreePhysicalMemory()
{
com.sun.management.OperatingSystemMXBean bean =
(com.sun.management.OperatingSystemMXBean)
java.lang.management.ManagementFactory.getOperatingSystemMXBean();
return bean.getFreePhysicalMemorySize();
}
first, extract ids from the collection where condition
List<int> indexes_Yes = this.Contenido.Where(x => x.key == 'TEST').Select(x => x.Id).ToList();
second, use "compare" estament to select ids diffent to the selection
List<int> indexes_No = this.Contenido.Where(x => !indexes_Yes.Contains(x.Id)).Select(x => x.Id).ToList();
Obviously you can use x.key != "TEST", but is only a example
Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express
(%PROGRAMFILES(x86)%\IIS Express
on x64 architectures) and its called iisexpress.exe
.
To see all the possible command-line options, just run:
iisexpress /?
and the program detailed help will show up.
If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.
There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config
): the /site
and /siteId
.
With the first one, you can launch a specific site by name:
iisexpress /site:SiteName
And with the latter, you can launch by specifying the ID:
iisexpress /siteId:SiteId
With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.
Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):
iisexpress /path:FullSitePath
This covers the basic IISExpress usage from the command line.
if you want to escape double quote in JSON use \\ to escape it.
example if you want to create json of following javascript object
{time: '7 "o" clock'}
then you must write in following way
'{"time":"7 \\"o\\" clock"}'
if we parse it using JSON.parse()
JSON.parse('{"time":"7 \\"o\\" clock"}')
result will be
{time: "7 "o" clock"}

After searching around I found a way to create a temp table dynamically for any stored procedure without using OPENROWSET
or OPENQUERY
using a generic schema of Stored Procedure's result definition especially when you are not database Administrator.
Sql server has a buit-in proc sp_describe_first_result_set
that can provide you with schema of any procedures resultset. I created a schema table from results of this procedure and manually set all the field to NULLABLE.
declare @procname varchar(100) = 'PROCEDURENAME' -- your procedure name
declare @param varchar(max) = '''2019-06-06''' -- your parameters
declare @execstr nvarchar(max) = N'exec ' + @procname
declare @qry nvarchar(max)
-- Schema table to store the result from sp_describe_first_result_set.

Some of the webservices require you to place request data and metadata separately. For example a remote function may expect that the signed metadata string is included in a URI, while the data is posted in a HTTP-body.
The POST request may semantically look like this:

The correct answer is:
_.omitBy({ a: null, b: 1, c: undefined, d: false }, _.isNil)
That results in:
{b: 1, d: false}
The alternative given here by other people:
_.pickBy({ a: null, b: 1, c: undefined, d: false }, _.identity);
Will remove also false
values which is not desired here.

while this one doesn't:

Not sure about the number of daily visits but here are a few examples of large Django sites:
Here is a link to list of high traffic Django sites on Quora.
Here is a very simple solution that worked well for me.
First declare a variable to hold your number.
var number;
Now convert the number to a string and hold it in another variable;
var numberStr = number.toString();
Now you can test the length of this string , if it is less than desired you can append a 'zero' at the beginning.
if(numberStr.length < 2){
number = '0' + number;
}
Now use the number as desired
console.log(number);
Try the following code :
$username='ABC';
$password='XYZ';
$URL='<URL>';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$URL);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //timeout after 30 seconds
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
$result=curl_exec ($ch);
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); //get status code
curl_close ($ch);
The typical use is
void* ret = NULL;
pthread_t tid = something; /// change it suitably
if (pthread_join (tid, &ret))
handle_error();
// do something with the return value ret
In this bit of code:
getRadioButtonValue(this["whichThing"]))
you're not actually getting a reference to anything. Therefore, your radiobutton in the getradiobuttonvalue function is undefined and throwing an error.
EDIT To get the value out of the radio buttons, grab the JQuery library, and then use this:
$('input[name=whichThing]:checked').val()
Edit 2 Due to the desire to reinvent the wheel, here's non-Jquery code:
var t = '';
for (i=0; i<document.myform.whichThing.length; i++) {
if (document.myform.whichThing[i].checked==true) {
t = t + document.myform.whichThing[i].value;
}
}
or, basically, modify the original line of code to read thusly:
getRadioButtonValue(document.myform.whichThing))
Edit 3 Here's your homework:
function handleClick() {
alert("Favorite weird creature: " + getRadioButtonValue(document.aye.whichThing));
//event.preventDefault(); // disable normal form submit behavior
return false; // prevent further bubbling of event
}
</script>
</head>
<body>
<form name="aye" onSubmit="return handleClick()">
<input name="Submit" type="submit" value="Update" />
Which of the following do you like best?
<p><input type="radio" name="whichThing" value="slithy toves" />Slithy toves</p>
<p><input type="radio" name="whichThing" value="borogoves" />Borogoves</p>
<p><input type="radio" name="whichThing" value="mome raths" />Mome raths</p>
</form>
Notice the following, I've moved the function call to the Form's "onSubmit" event. An alternative would be to change your SUBMIT button to a standard button, and put it in the OnClick event for the button. I also removed the unneeded "JavaScript" in front of the function name, and added an explicit RETURN on the value coming out of the function.
In the function itself, I modified the how the form was being accessed. The structure is: document.[THE FORM NAME].[THE CONTROL NAME] to get at things. Since you renamed your from aye, you had to change the document.myform. to document.aye. Additionally, the document.aye["whichThing"] is just wrong in this context, as it needed to be document.aye.whichThing.
The final bit, was I commented out the event.preventDefault();. that line was not needed for this sample.
EDIT 4 Just to be clear. document.aye["whichThing"] will provide you direct access to the selected value, but document.aye.whichThing gets you access to the collection of radio buttons which you then need to check. Since you're using the "getRadioButtonValue(object)" function to iterate through the collection, you need to use document.aye.whichThing.
See the difference in this method:
function handleClick() {
alert("Direct Access: " + document.aye["whichThing"]);
alert("Favorite weird creature: " + getRadioButtonValue(document.aye.whichThing));
return false; // prevent further bubbling of event
}
You have not provided enough code to help You likely submit the form and reload the page OR you have an object on the page like an embedded PDF that steals the focus.
Here is the canonical plain javascript method of validating a form It can be improved with onubtrusive JS which will remove the inline script, but this is the starting point DEMO
function validate(formObj) {
document.getElementById("errorMsg").innerHTML = "";
var quantity = formObj.quantity;
if (isNaN(quantity)) {
quantity.value="";
quantity.focus();
document.getElementById("errorMsg").innerHTML = "Only numeric value is allowed";
return false;
}
return true; // allow submit
}
Here is the HTML
<form onsubmit="return validate(this)">
<input type="text" name="quantity" value="" />
<input type="submit" />
</form>
<span id="errorMsg"></span>
See if your script is running GPU in Task manager. If not, suspect your CUDA version is right one for the tensorflow version you are using, as the other answers suggested already.
Additionally, a proper CUDA DNN library for the CUDA version is required to run GPU with tensorflow. Download/extract it from here and put the DLL (e.g., cudnn64_7.dll) into CUDA bin folder (e.g., C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin).

No need to use a macro. Supposing your first string is in A1.
=RIGHT(A1, 4)
Drag this down and you will get your four last characters.
Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()
=RIGHT(TRIMSPACES(A1), 4)
Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:
=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))
I try to explain it more understandably than the referred PostgreSQL documentation.
Neither TIMESTAMP
variants store a time zone (or an offset), despite what the names suggest. The difference is in the interpretation of the stored data (and in the intended application), not in the storage format itself:
TIMESTAMP WITHOUT TIME ZONE
stores local date-time (aka. wall calendar date and wall clock time). Its time zone is unspecified as far as PostgreSQL can tell (though your application may knows what it is). Hence, PostgreSQL does no time zone related conversion on input or output. If the value was entered into the database as '2011-07-01 06:30:30'
, then no mater in what time zone you display it later, it will still say year 2011, month 07, day 01, 06 hours, 30 minutes, and 30 seconds (in some format). Also, any offset or time zone you specify in the input is ignored by PostgreSQL, so '2011-07-01 06:30:30+00'
and '2011-07-01 06:30:30+05'
are the same as just '2011-07-01 06:30:30'
.
For Java developers: it's analogous to java.time.LocalDateTime
.
TIMESTAMP WITH TIME ZONE
stores a point on the UTC time line. How it looks (how many hours, minutes, etc.) depends on your time zone, but it always refers to the same "physical" instant (like the moment of an actual physical event). The
input is internally converted to UTC, and that's how it's stored. For that, the offset of the input must be known, so when the input contains no explicit offset or time zone (like '2011-07-01 06:30:30'
) it's assumed to be in the current time zone of the PostgreSQL session, otherwise the explicitly specified offset or time zone is used (as in '2011-07-01 06:30:30+05'
). The output is displayed converted to the current time zone of the PostgreSQL session.
For Java developers: It's analogous to java.time.Instant
(with lower resolution though), but with JDBC and JPA 2.2 you are supposed to map it to java.time.OffsetDateTime
(or to java.util.Date
or java.sql.Timestamp
of course).
Some say that both TIMESTAMP
variations store UTC date-time. Kind of, but it's confusing to put it that way in my opinion. TIMESTAMP WITHOUT TIME ZONE
is stored like a TIMESTAMP WITH TIME ZONE
, which rendered with UTC time zone happens to give the same year, month, day, hours, minutes, seconds, and microseconds as they are in the local date-time. But it's not meant to represent the point on the time line that the UTC interpretation says, it's just the way the local date-time fields are encoded. (It's some cluster of dots on the time line, as the real time zone is not UTC; we don't know what it is.)
Open SQL Developer. Go to Tools -> Preferences -> Databases -> Advanced Then explicitly set the Tnsnames Directory
My TNSNAMES was set up correctly and I could connect to Toad, SQL*Plus etc. but I needed to do this to get SQL Developer to work. Perhaps it was a Win 7 issue as it was a pain to install too.
Caveat Emptor - Destructive commands ahead.
Mitigation - git reflog
can save you if you need it.
1) UNDO local file changes and KEEP your last commit
git reset --hard
2) UNDO local file changes and REMOVE your last commit
git reset --hard HEAD^
3) KEEP local file changes and REMOVE your last commit
git reset --soft HEAD^
As said in the documentation:
Must: The clause (query) must appear in matching documents.
Should: The clause (query) should appear in the matching document. In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.
In other words, results will have to be matched by all the queries present in the must clause ( or match at least one of the should clauses if there is no must clause.
Since you want your results to satisfy all the queries, you should use must.
You can indeed use filters inside a boolean query.

This is a warning for usual. You can either disable it by

or simply use fopen_s like Microsoft has intended.
But be sure to use the pragma before other headers.
CURL is the simplest way to go. Here is a simple call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "THE URL TO THE SERVICE");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, POST DATA);
$result = curl_exec($ch);

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:
launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"
To directly answer your question, you can add launchctl line in your ~/.bash_profile
As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.
If you dont have an entry point defined in your manifest invoking java -jar foo.jar
will not work.
Use this command if you dont have a manifest or to run a different main class than the one specified in the manifest:
java -cp foo.jar full.package.name.ClassName
See also instructions on how to create a manifest with an entry point: https://docs.oracle.com/javase/tutorial/deployment/jar/appman.html
From MYSQL I solved the problem like this:
SUM(CASE WHEN used = 1 THEN 1 ELSE 0 END) as amount_one,
Hope this helps :D
Others have answered in terms of how to handle the specific escaping in this case.
A broader answer is not to try to do it yourself. Use an XML API - there are plenty available for just about every modern programming platform in existence.
XML APIs will handle things like this for you automatically, making it a lot harder to go wrong. Unless you're writing an XML API yourself, you should rarely need to worry about the details like this.
With querySelectorAll you can select the elements you want without the same id using css selector:
var elems = document.querySelectorAll("#id1, #id1, #id3");
Pipe the result to wc
using the -l
(line count) switch:
grep -Rl "curl" ./ | wc -l
Like you, I'm building a chat app and want the most recent message to scroll into view. This ultimately worked well for me:
//get the div that contains all the messages
let div = document.getElementById('message-container');
//make the last element (a message) to scroll into view, smoothly!
div.lastElementChild.scrollIntoView({ behavior: 'smooth' });
Use time.sleep()
from time import sleep
sleep(0.05)
Apparently, org.json.simple.JSONArray
implements a raw Iterator. This means that each element is considered to be an Object
. You can try to cast:
for(Object o: arr){
if ( o instanceof JSONObject ) {
parse((JSONObject)o);
}
}
This is how things were done back in Java 1.4 and earlier.
Why to annoy the user with three different Dialog Boxes to enter things, why not do all this in one go in a single Dialog and save time, instead of testing the patience of the USER ?

To create a jupyter_notebook_config.py file, with all the defaults commented out, you can use the following command line:
$ jupyter notebook --generate-config
Open the file and search for c.NotebookApp.iopub_data_rate_limit
Comment out the line c.NotebookApp.iopub_data_rate_limit = 1000000
and change it to a higher default rate. l used c.NotebookApp.iopub_data_rate_limit = 10000000
This unforgiving default config is popping up in a lot of places. See git issues:
It looks like it might get resolved with the 5.1 release
Jupyter notebook is now on release 5.2.2

Is the image file ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg in your static
directory? If you move it to your static directory and update your HTML as such:
<img src="/static/ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg">
It should work.
Also, it is worth noting, there is a better way to structure this.
File structure:
app.py
static
|----ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg
templates
|----index.html
app.py
from flask import Flask, render_template, url_for
app = Flask(__name__)
@app.route('/index', methods=['GET', 'POST'])
def lionel():
return render_template('index.html')
if __name__ == '__main__':
app.run()
templates/index.html
<html>
<head>
</head>
<body>
<h1>Hi Lionel Messi</h1>
<img src="{{url_for('static', filename='ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg')}}" />
</body>
</html>
Doing it this way ensures that you are not hard-coding a URL path for your static assets.

In all schemas:

In a particular schema:

It is possible to use regular expressions with some restrictions
\dt (public|s).(s|t)

public | t | table | cpn
s | t | table | cpn
Advanced users can use regular-expression notations such as character classes, for example [0-9] to match any digit. All regular expression special characters work as specified in Section 9.7.3, except for
.
which is taken as a separator as mentioned above,*
which is translated to the regular-expression notation.*
,?
which is translated to.
, and$
which is matched literally. You can emulate these pattern characters at need by writing?
for.
,(R+|)
forR*
, or(R|)
forR?
.$
is not needed as a regular-expression character since the pattern must match the whole name, unlike the usual interpretation of regular expressions (in other words,$
is automatically appended to your pattern). Write*
at the beginning and/or end if you don't wish the pattern to be anchored. Note that within double quotes, all regular expression special characters lose their special meanings and are matched literally. Also, the regular expression special characters are matched literally in operator name patterns (i.e., the argument of\do
).
Had the same problem with base64. For anyone in the future with the same problem:
url = "data:image/png;base64,iVBORw0KGgoAAAAAAAAyCAYAAAAUYybjAAAgAElE...";
This would work executed from console, but not from within a script:
$img.css("background-image", "url('" + url + "')");
But after playing with it a bit, I came up with this:
var img = new Image();
img.src = url;
$img.css("background-image", "url('" + img.src + "')");
No idea why it works with a proxy image, but it does. Tested on Firefox Dev 37 and Chrome 40.
Hope it helps someone.
EDIT
Investigated a little bit further. It appears that sometimes base64 encoding (at least in my case) breaks with CSS because of line breaks present in the encoded value (in my case value was generated dynamically by ActionScript).
Simply using e.g.:
$img.css("background-image", "url('" + url.replace(/(\r\n|\n|\r)/gm, "") + "')");
works too, and even seems to be faster by a few ms than using a proxy image.

This fixed it for me:
export DISPLAY="localhost:10.0"
You can use this too:
export DISPLAY="127.0.0.1:10.0"
The probable reason why you get this error is likely because you've added the /build folder to your .gitignore file or generally haven't checked it into Git.
So when you Git push Heroku master, the build folder you're referencing don't get pushed to Heroku. And that's why it shows this error.
That's the reason it works properly locally, but not when you deployed to Heroku.

None of the above answers is currently working for me. It turns out that .scrollTo
is not as widely compatible as .scrollIntoView
.
In our App.js, in componentWillMount()
we added
this.props.history.listen((location, action) => {
setTimeout(() => { document.getElementById('root').scrollIntoView({ behavior: "smooth" }) }, 777)
})
This is the only solution that is working universally for us. root is the ID of our App. The "smooth" behavior doesn't work on every browser / device. The 777 timeout is a bit conservative, but we load a lot of data on every page, so through testing this was necessary. A shorter 237 might work for most applications.

I'm not sure whether this would be a requirement, but may help!
How are you doing the compiling and linking? You'll need to specify both files, something like:
gcc testpoint.c point.c
...so that it knows to link the functions from both together. With the code as it's written right now, however, you'll then run into the opposite problem: multiple definitions of main
. You'll need/want to eliminate one (undoubtedly the one in point.c).
In a larger program, you typically compile and link separately to avoid re-compiling anything that hasn't changed. You normally specify what needs to be done via a makefile, and use make
to do the work. In this case you'd have something like this:
OBJS=testpoint.o point.o
testpoint.exe: $(OBJS)
gcc $(OJBS)
The first is just a macro for the names of the object files. You get it expanded with $(OBJS)
. The second is a rule to tell make 1) that the executable depends on the object files, and 2) telling it how to create the executable when/if it's out of date compared to an object file.
Most versions of make (including the one in MinGW I'm pretty sure) have a built-in "implicit rule" to tell them how to create an object file from a C source file. It normally looks roughly like this:
.c.o:
$(CC) -c $(CFLAGS) $<
This assumes the name of the C compiler is in a macro named CC (implicitly defined like CC=gcc
) and allows you to specify any flags you care about in a macro named CFLAGS
(e.g., CFLAGS=-O3
to turn on optimization) and $<
is a special macro that expands to the name of the source file.
You typically store this in a file named Makefile
, and to build your program, you just type make
at the command line. It implicitly looks for a file named Makefile
, and runs whatever rules it contains.
The good point of this is that make
automatically looks at the timestamps on the files, so it will only re-compile the files that have changed since the last time you compiled them (i.e., files where the ".c" file has a more recent time-stamp than the matching ".o" file).
Also note that 1) there are lots of variations in how to use make when it comes to large projects, and 2) there are also lots of alternatives to make. I've only hit on the bare minimum of high points here.
Doing type('')
is effectively equivalent to str
and types.StringType
so type('') == str == types.StringType
will evaluate to "True
"
Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode)
or assert isinstance(obj, basestring)
, the latter of which was suggested in the comments by 007Brendan and is probably preferred.
isinstance()
is useful if you want to ask whether an object is an instance of a class, e.g:
class MyClass: pass
print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception
But for basic types, e.g. str
, unicode
, int
, float
, long
etc asking type(var) == TYPE
will work OK.
Just use notepad ++ with encoding UTF-8 without BOM.
In short, always prefer initialization lists when possible. 2 reasons:
If you do not mention a variable in a class's initialization list, the constructor will default initialize it before entering the body of the constructor you've written. This means that option 2 will lead to each variable being written to twice, once for the default initialization and once for the assignment in the constructor body.
Also, as mentioned by mwigdahl and avada in other answers, const members and reference members can only be initialized in an initialization list.
Also note that variables are always initialized on the order they are declared in the class declaration, not in the order they are listed in an initialization list (with proper warnings enabled a compiler will warn you if a list is written out of order). Similarly, destructors will call member destructors in the opposite order, last to first in the class declaration, after the code in your class's destructor has executed.
