If the emulator is running and is not being detected by the flutter
and adb devices
then try connecting it manually by using the following command
abd connect 127.0.0.1:62001
If it fails to connect, try again. The following message should appear
connected to 127.0.0.1:62001
Then try flutter doctor
or adb devices
to make sure it has been connected successfully.
I ported the C# sample to Objective-c and didn't see it in the responses:
//Usage
NSMutableArray* numberList = [[NSMutableArray alloc] init];
NSMutableArray* partial = [[NSMutableArray alloc] init];
int target = 16;
for( int i = 1; i<target; i++ )
{ [numberList addObject:@(i)]; }
[self findSums:numberList target:target part:partial];
//*******************************************************************

int s = 0;
for (NSNumber* x in partial)
{ s += [x intValue]; }
if (s == target)
{ NSLog(@"Sum[%@]", partial); }
if (s >= target)
{ return; }
for (int i = 0;i < [numbers count];i++ )
{
int n = [numbers[i] intValue];

NSMutableArray* partRec = [[NSMutableArray alloc] initWithArray:partial];
[partRec addObject:@(n)];

Here is another way to use SQL SELECT
statement in VBA:
sSQL = "SELECT Variable FROM GroupTable WHERE VariableCode = '" & Me.comboBox & "'"
Set rs = CurrentDb.OpenRecordset(sSQL)
On Error GoTo resultsetError
dbValue = rs!Variable
MsgBox dbValue, vbOKOnly, "RS VALUE"
resultsetError:
MsgBox "Error Retrieving value from database",VbOkOnly,"Database Error"
<!--something like this-->
<html>
<body>
<!-- i've used for loop...this pointer takes current element to apply a
particular change on it ...other elements take change by else condition
-->
<div class="classname" onclick="myFunction(this);">first</div>
<div class="classname" onclick="myFunction(this);">second</div>
<script>
function myFunction(p) {
var x = document.getElementsByClassName("classname");
var i;
for (i = 0; i < x.length; i++) {
if(x[i] == p)
{
x[i].style.background="blue";
}
else{
x[i].style.background="red";
}
}
}
</script>
<!--this script will only work for a class with onclick event but if u want
to use all class of same name then u can use querySelectorAll() ...-->
var variable_name=document.querySelectorAll('.classname');
for(var i=0;i<variable_name.length;i++){

It's more generic and will fit for any array!!
In my case the version of the dll referenced was actually newer than the one that I had before.
I just needed to roll back to the previous release and that fixed it.
For Chrome, for instance:
a. To do so, by opening the 'Elements' panel of the browser, press CTRL+F, paste the XPath.
b. Make changes as describes in the following example.
Absolute xpath = //*[@id="app"]/div[1]/header/nav/div[2]/ul/li[2]/div/button
Related xpath = //div//nav/div[2]/ul/li[2]/div/button
When you make changes:
Maybe something changed since 2011 but this worked for me:
$ date +"%Y%m%d"
20150330
No need for the -d
to get the same appearing result.

request.send(null);
var jsonData = JSON.parse(request.responseText);
console.log(jsonData);
For me below solution worked.
Jenkins --> Manage Jenkins --> Manage Nodes --> master -> configure --> Node properties --> Restrict Jobs execution at node - is enabled and given access to specific users. I have given access myself and then job started to run.
If Restrict Jobs execution at node is enabled scheduled tasks cannot run.
Looks like the solution as.numeric(levels(f))[f] no longer work with R 4.0.
Alternative solution:
factor2number <- function(x){
data.frame(levels(x), 1:length(levels(x)), row.names = 1)[x, 1]
}
factor2number(yourFactor)
I think this solution is the shortest :
df= df[df['ColName'] != 0]
You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:
https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899
In this example, question 1, "Name", has an ID of 726721210
, while question 2, "Birthday" is 787184751
. Questions 3 and 4 are blank.
You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:
function buildUrls() {
var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1"); // Email, Name, Birthday
var data = ss.getDataRange().getValues();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
var url = template.replace('##Name##',escape(data[i][1]))
.replace('##Birthday##',data[i][2].yyyymmdd()); // see yyyymmdd below
Logger.log(url); // You could do something more useful here.
}
};
This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.
Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.
Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0]
is "Name", [1]
is "Birthday", and so on.
We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.
(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)
/**
* Use Form API to generate pre-filled form URLs
*/
function betterBuildUrls() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Sheet1");
var data = ss.getDataRange().getValues(); // Data for pre-fill
var formUrl = ss.getFormUrl(); // Use form attached to sheet
var form = FormApp.openByUrl(formUrl);
var items = form.getItems();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
// Create a form response object, and prefill it
var formResponse = form.createResponse();
// Prefill Name
var formItem = items[0].asTextItem();
var response = formItem.createResponse(data[i][1]);
formResponse.withItemResponse(response);
// Prefill Birthday
formItem = items[1].asDateItem();
response = formItem.createResponse(data[i][2]);
formResponse.withItemResponse(response);
// Get prefilled form URL
var url = formResponse.toPrefilledUrl();
Logger.log(url); // You could do something more useful here.
}
};
Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd
. This helper function extends the Date object with a new method to handle the conversion.
When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975
you could use 5/9/1975
.)
// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

New approach to old question. A solution that works from java 9+
ObjectNode agencyNode = new ObjectMapper().valueToTree(Map.of("key", "value"));
is more readable and maintainable for complex objects. Ej
Map<String, Object> agencyMap = Map.of(
"name", "Agencia Prueba",
"phone1", "1198788373",
"address", "Larrea 45 e/ calligaris y paris",
"number", 267,
"enable", true,
"location", Map.of("id", 54),
"responsible", Set.of(Map.of("id", 405)),
"sellers", List.of(Map.of("id", 605))
);
ObjectNode agencyNode = new ObjectMapper().valueToTree(agencyMap);
Try this:
SELECT user.userID, edge.TailUser, edge.Weight
FROM user
LEFT JOIN edge ON edge.HeadUser = User.UserID
WHERE edge.HeadUser=5043
OR
AND edge.HeadUser=5043
instead of WHERE clausule.
Your line:
img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.
Try
cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
You can serialize the object to derive a measure that is closely related to the size of the object:
import pickle
## let o be the object whose size you want to measure
size_estimate = len(pickle.dumps(o))
If you want to measure objects that cannot be pickled (e.g. because of lambda expressions) dill or cloudpickle can be a solution.
Indexing in python starting from 0. You wrote [1:] this would not return you a first char in any case - this will return you a rest(except first char) of string.
If you have the following structure:
mylist = ['base', 'sample', 'test']
And want to get fist char for the first one string(item):
myList[0][0]
>>> b
If all first chars:
[x[0] for x in myList]
>>> ['b', 's', 't']
If you have a text:
text = 'base sample test'
text.split()[0][0]
>>> b
Going off of what Derloopkat said, which still can fail on conversion (no offense Derloopkat) because Excel is terrible at this:
It will open, check it to make sure it's accurate and then save as an excel file.
Destroy the datepicker's instance when you don't want it and create new instance whenever necessary.
I know this is ugly but only this seems to be working...
$("#ddlSearchType").change(function () {
if ($(this).val() == "Required Date" || $(this).val() == "Submitted Date") {
$("#txtSearch").datepicker();
}
else {
$("#txtSearch").datepicker("destroy");
}
});
I'm pretty sure you can completely delete the <stuff> , which will generate a warning and you can use an, @ suppress warnings. If you really want it to be generic, but to use any of its elements you will have to do type casting. For instance, I made a simple bubble sort function and it uses a generic type when sorting the list, which is actually an array of Comparable in this case. If you wish to use an item, do something like: System.out.println((Double)arrayOfDoubles[0] + (Double)arrayOfDoubles[1]); because I stuffed Double(s) into Comparable(s) which is polymorphism since all Double(s) inherit from Comparable to allow easy sorting through Collections.sort()
//INDENT TO DISPLAY CODE ON STACK-OVERFLOW

if you use fragment u should use
getActivity().onBackPressed();
if you use single activity u can use
finish();
Or
help(list.append)
if you're generally poking around.
From the help file about $
(See ?"$"
) you can read:
$ is only valid for recursive objects, and is only discussed in the section below on recursive objects.
Now, let's check whether x
is recursive
> is.recursive(x)
[1] FALSE
A recursive object has a list-like structure. A vector is not recursive, it is an atomic object instead, let's check
> is.atomic(x)
[1] TRUE
Therefore you get an error when applying $
to a vector (non-recursive object), use [
instead:
> x["ed"]
ed
2
You can also use getElement
> getElement(x, "ed")
[1] 2
Just the thread.
developer.android.com has nice example code for this: https://developer.android.com/guide/topics/providers/document-provider.html
A condensed version to just extract the file name (assuming "this" is an Activity):
public String getFileName(Uri uri) {
String result = null;
if (uri.getScheme().equals("content")) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
try {
if (cursor != null && cursor.moveToFirst()) {
result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}
} finally {
cursor.close();
}
}
if (result == null) {
result = uri.getPath();
int cut = result.lastIndexOf('/');
if (cut != -1) {
result = result.substring(cut + 1);
}
}
return result;
}
let's me give a more detail example:
import numpy as np
import matplotlib.pyplot as plt
def draw_result(lst_iter, lst_loss, lst_acc, title):
plt.plot(lst_iter, lst_loss, '-b', label='loss')
plt.plot(lst_iter, lst_acc, '-r', label='accuracy')
plt.xlabel("n iteration")
plt.legend(loc='upper left')
plt.title(title)
plt.savefig(title+".png") # should before plt.show method
plt.show()
def test_draw():
lst_iter = range(100)
lst_loss = [0.01 * i + 0.01 * i ** 2 for i in xrange(100)]
# lst_loss = np.random.randn(1, 100).reshape((100, ))
lst_acc = [0.01 * i - 0.01 * i ** 2 for i in xrange(100)]
# lst_acc = np.random.randn(1, 100).reshape((100, ))
draw_result(lst_iter, lst_loss, lst_acc, "sgd_method")
if __name__ == '__main__':
test_draw()
here is a sample of code using the CopyMemory
function to do the job.
It is supposedly "much faster" (depending of the size and type of the array...).
i am not the author, but i tested it :
Sub RemoveArrayElement_Str(ByRef AryVar() As String, ByVal RemoveWhich As Long)
'// The size of the array elements
'// In the case of string arrays, they are
'// simply 32 bit pointers to BSTR's.
Dim byteLen As Byte
'// String pointers are 4 bytes
byteLen = 4
'// The copymemory operation is not necessary unless
'// we are working with an array element that is not
'// at the end of the array
If RemoveWhich < UBound(AryVar) Then
'// Copy the block of string pointers starting at
' the position after the
'// removed item back one spot.
CopyMemory ByVal VarPtr(AryVar(RemoveWhich)), ByVal _
VarPtr(AryVar(RemoveWhich + 1)), (byteLen) * _
(UBound(AryVar) - RemoveWhich)
End If
'// If we are removing the last array element
'// just deinitialize the array
'// otherwise chop the array down by one.
If UBound(AryVar) = LBound(AryVar) Then
Erase AryVar
Else
ReDim Preserve AryVar(LBound(AryVar) To UBound(AryVar) - 1)
End If
End Sub
If you want to split only by newlines, you can use str.splitlines():
Example:
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data
'a,b,c\nd,e,f\ng,h,i\nj,k,l'
>>> data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
With str.split() your case also works:
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data
'a,b,c\nd,e,f\ng,h,i\nj,k,l'
>>> data.split()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
However if you have spaces (or tabs) it will fail:
>>> data = """
... a, eqw, qwe
... v, ewr, err
... """
>>> data
'\na, eqw, qwe\nv, ewr, err\n'
>>> data.split()
['a,', 'eqw,', 'qwe', 'v,', 'ewr,', 'err']
VAR=value
sets VAR to value.
After that export VAR
will give it to child processes too.
export VAR=value
is a shorthand doing both.
Over on this duplicate question @arcticdev posted some code that will get rid of individual entries (as opposed to all entries being delete the bin file). I have wrapped it in a very ugly UI and put it here: http://ssmsmru.codeplex.com/
The OP is asking about whether it is possible to add an Attribute to an Entity class for a Unique Key. The short answer is that it IS possible, but not an out-of-the-box feature from the EF Core Team. If you'd like to use an Attribute to add Unique Keys to your Entity Framework Core entity classes, you can do what I've posted here
public class Company
{
[Required]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public Guid CompanyId { get; set; }
[Required]
[UniqueKey(groupId: "1", order: 0)]
[StringLength(100, MinimumLength = 1)]
public string CompanyName { get; set; }
[Required]
[UniqueKey(groupId: "1", order: 1)]
[StringLength(100, MinimumLength = 1)]
public string CompanyLocation { get; set; }
}
<link rel="shortcut icon" type="image/x-icon" href="~/favicon.ico" />

This worked for me. If anyone is troubleshooting while reading this - I found issues when my favicon.ico was not nested in the root folder. I had mine in the Resources folder and was struggling at that point.
We dont need redux-persist we can simply use redux for persistance.
react-redux + AsyncStorage = redux-persist
so inside createsotre file simply add these lines
store.subscribe(async()=> await AsyncStorage.setItem("store", JSON.stringify(store.getState())))
this will update the AsyncStorage whenever there are some changes in the redux store.
Then load the json converted store. when ever the app loads. and set the store again.
Because redux-persist creates issues when using wix react-native-navigation. If that's the case then I prefer to use simple redux with above subscriber function
Don't use an array if you want named keys, use a plain object.
var a = {};
a["key1"] = "value1";
a["key2"] = "value2";
Then:
if ("key1" in a) {
// something
} else {
// something else
}
The only way that i know of is to test for it, you can do a combined if though to make it easy.
If NOT IsDbNull(myItem("sID")) AndAlso myItem("sID") = sId Then
'Do success
ELSE
'Failure
End If
I wrote in VB as that is what it looks like you need, even though you mixed languages.
Edit
Cleaned up to use IsDbNull to make it more readable
This is probably system-dependent, but this is the simplest way I've found.

That's the best solution for scripting.
You'll need to join twice:

INNER JOIN team AS home
ON home.importid = g.home
INNER JOIN team AS away
ON away.importid = g.away
ORDER BY g.date_start DESC

I accidentally deleted a whole bunch of data in the wrong environment and this post was one of the first ones I found.
Because I was simultaneously panicking and searching for a solution, I went for the first thing I saw - ApexSQL Logs, which was $2000 which was an acceptable cost.
However, I've since found out that Toad for Sql Server can generate undo scripts from transaction logs and it is only $655.
Lastly, found an even cheaper option SysToolsGroup Log Analyzer and it is only $300.
I just found out that the following works:

Working with Git 2.3.2 ...
git branch --set-upstream-to myfork/master
Now status
, push
and pull
are pointed to myfork
remote
To install only from local you need 2 options:
--find-links
: where to look for dependencies. There is no need for the file://
prefix mentioned by others.--no-index
: do not look in pypi indexes for missing dependencies (dependencies not installed and not in the --find-links
path). So you could run from any folder the following:
pip install --no-index --find-links /srv/pkg /path/to/mypackage-0.1.0.tar.gz
If your mypackage is setup properly, it will list all its dependencies, and if you used pip download to download the cascade of dependencies (ie dependencies of depencies etc), everything will work.
If you want to use the pypi index if it is accessible, but fallback to local wheels if not, you can remove --no-index
and add --retries 0
. You will see pip pause for a bit while it is try to check pypi for a missing dependency (one not installed) and when it finds it cannot reach it, will fall back to local. There does not seem to be a way to tell pip to "look for local ones first, then the index".
Git does not have the same concept of revision numbers as subversion. Instead each given snapshot made with a commit is tagged by a SHA1 checksum. Why? There are several problems with a running revno in a distributed version control system:
First, since development is not linear at all, the attachment of a number is rather hard as a problem to solve in a way which will satisfy your need as a programmer. Trying to fix this by adding a number might quickly become problematic when the number does not behave as you expect.
Second, revision numbers may be generated on different machines. This makes synchronization of numbers much harder - especially since connectivity is one-way; you may not even have access to all machines that has the repository.
Third, in git, somewhat pioneered by the now defunct OpenCM system, the identity of a commit (what the commit is) is equivalent to its name (the SHA id). This naming = identity concept is very strong. When you sit with a commit name in hand it also identifies the commit in an unforgeable way. This in turn lets you check all of your commits back to the first initial one for corruption with the git fsck
command.
Now, since we have a DAG (Directed Acyclic Graph) of revisions and these constitute the current tree, we need some tools to solve your problem: How do we discriminate different versions. First, you can omit part of the hash if a given prefix, 1516bd say, uniquely identifies your commit. But this is also rather contrived. Instead, the trick is to use tags and or branches. A tag or branch is akin to a "yellow stick it note" you attach to a given commit SHA1-id. Tags are, in essence, meant to be non-moving whereas a branch will move when new commits are made to its HEAD. There are ways to refer to a commit around a tag or branch, see the man page of git-rev-parse.
Usually, if you need to work on a specific piece of code, that piece is undergoing changes and should as such be a branch with a saying topic name. Creating lots of branches (20-30 per programmer is not unheard of, with some 4-5 published for others to work on) is the trick for effective git. Every piece of work should start as its own branch and then be merged in when it is tested. Unpublished branches can be rewritten entirely and this part of destroying history is a force of git.
When the change is accepted into master it somewhat freezes and becomes archeology. At that point, you can tag it, but more often a reference to the particular commit is made in a bug tracker or issue tracker via the sha1 sum. Tags tend to be reserved for version bumps and branch points for maintenance branches (for old versions).
You can try following way

@Html.TextBoxFor(x => x.FileName, new { @id = "doc", @type = "file", @accept = "application/pdf,.csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" })

You can use an API call and Sleep:
Put this at the top of your module:
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Then you can call it in a procedure like this:
Sub test()
Dim i As Long
For i = 1 To 10
Debug.Print Now()
Sleep 500 'wait 0.5 seconds
Next i
End Sub
BigDecimal
isn't a primitive, so you cannot use the <
, >
operators. However, since it's a Comparable
, you can use the compareTo(BigDecimal)
to the same effect. E.g.:
public class Domain {
private BigDecimal unitPrice;
public boolean isCheaperThan(BigDecimal other) {
return unitPirce.compareTo(other.unitPrice) < 0;
}
// etc...
}
Find end position of file:
f = open("file.txt","r")
f.seek(0,2) #Jumps to the end
f.tell() #Give you the end location (characters from start)
f.seek(0) #Jump to the beginning of the file again
Then you can to:
if line == '' and f.tell() == endLocation:
break

it is possible in linked list.
you have to make toString() in song class. if you don't it will print out reference of the song.
probably irrelevant for you by now. ^_^
I found a more straight forward solution from @DK comment in this question, the solution is written by Alex and described here with source, To make customized window:
I ended up figuring out a (pretty good) solution for this problem!
You can use a TransitionDrawable to accomplish this. For example, in an XML file in the drawable folder you could write something like:
<?xml version="1.0" encoding="UTF-8"?>
<transition xmlns:android="http://schemas.android.com/apk/res/android">
<!-- The drawables used here can be solid colors, gradients, shapes, images, etc. -->
<item android:drawable="@drawable/original_state" />
<item android:drawable="@drawable/new_state" />
</transition>
Then, in your XML for the actual View you would reference this TransitionDrawable in the android:background
attribute.
At this point you can initiate the transition in your code on-command by doing:
TransitionDrawable transition = (TransitionDrawable) viewObj.getBackground();
transition.startTransition(transitionTime);
Or run the transition in reverse by calling:
transition.reverseTransition(transitionTime);
See Roman's answer for another solution using the Property Animation API, which wasn't available at the time this answer was originally posted.
First of all it is unclear what type name has. If it has the type std::string
then instead of
string nametext;
nametext = "Your name is" << name;
you should write
std::string nametext = "Your name is " + name;
where operator + serves to concatenate strings.
If name
is a character array then you may not use operator + for two character arrays (the string literal is also a character array), because character arrays in expressions are implicitly converted to pointers by the compiler. In this case you could write
std::string nametext( "Your name is " );
nametext.append( name );
or
std::string nametext( "Your name is " );
nametext += name;
you can add a condition to the after_update
like so:
class SomeModel < ActiveRecord::Base
after_update :send_notification, if: :published_changed?
...
end
there's no need to add a condition within the send_notification
method itself.
Try this:
$comments_collection = $post->comments()->get()->toArray();
see this can help you

There are a variety of accurate answers here, but here is the most concise code for several different variations. For each variation, the top line shows the full syntax and the bottom shows terse syntax.
Item (2) is a more concise form of the answers from Jon Z and manojlds, while item (1) is equivalent to the answers from vikas368 and buygrush.
List FileInfo objects for all files containing pattern:
Get-ChildItem -Recurse filespec | Where-Object { Select-String pattern $_ -Quiet }
ls -r filespec | ? { sls pattern $_ -q }
List file names for all files containing pattern:
Get-ChildItem -Recurse filespec | Select-String pattern | Select-Object -Unique Path
ls -r filespec | sls pattern | select -u Path
List FileInfo objects for all files not containing pattern:
Get-ChildItem -Recurse filespec | Where-Object { !(Select-String pattern $_ -Quiet) }
ls -r filespec | ? { !(sls pattern $_ -q) }
List file names for all files not containing pattern:
(Get-ChildItem -Recurse filespec | Where-Object { !(Select-String pattern $_ -Quiet) }).FullName
(ls -r filespec | ? { !(sls pattern $_ -q) }).FullName

}
you also can add this inline instead of config, just add it to the same file before you add your own disable stuff

my case was disable a file and eslint-disable were not working for me alone

If you want an interactive heatmap from a Pandas DataFrame and you are running a Jupyter notebook, you can try the interactive Widget Clustergrammer-Widget, see interactive notebook on NBViewer here, documentation here
And for larger datasets you can try the in-development Clustergrammer2 WebGL widget (example notebook here)
I would recommend checking out Gabor Grothendieck's sqldf package, which allows you to express these operations in SQL.
library(sqldf)
## inner join
df3 <- sqldf("SELECT CustomerId, Product, State
FROM df1
JOIN df2 USING(CustomerID)")
## left join (substitute 'right' for right join)
df4 <- sqldf("SELECT CustomerId, Product, State
FROM df1
LEFT JOIN df2 USING(CustomerID)")
I find the SQL syntax to be simpler and more natural than its R equivalent (but this may just reflect my RDBMS bias).
See Gabor's sqldf GitHub for more information on joins.
Your Window is not implementing the necessary data binding notifications that the grid requires to use it as a data source, namely the INotifyPropertyChanged interface.
Your "Name2" string needs also to be a property and not a public variable, as data binding is for use with properties.
Implementing the necessary interfaces for using an object as a data source can be found here.
And in 2016.....I do this (which works in all browsers and does not create "illegal" html).
For the drop-down select that is to show/hide different values add that value as a data attribute.
<select id="animal">
<option value="1" selected="selected">Dog</option>
<option value="2">Cat</option>
</select>
<select id="name">
<option value=""></option>
<option value="1" data-attribute="1">Rover</option>
<option value="2" selected="selected" data-attribute="1">Lassie</option>
<option value="3" data-attribute="1">Spot</option>
<option value="4" data-attribute="2">Tiger</option>
<option value="5" data-attribute="2">Fluffy</option>
</select>
Then in your jQuery add a change event to the first drop-down select to filter the second drop-down.
$("#animal").change( function() {
filterSelectOptions($("#name"), "data-attribute", $(this).val());
});
And the magic part is this little jQuery utility.
function filterSelectOptions(selectElement, attributeName, attributeValue) {
if (selectElement.data("currentFilter") != attributeValue) {
selectElement.data("currentFilter", attributeValue);
var originalHTML = selectElement.data("originalHTML");
if (originalHTML)
selectElement.html(originalHTML)
else {
var clone = selectElement.clone();
clone.children("option[selected]").removeAttr("selected");
selectElement.data("originalHTML", clone.html());
}
if (attributeValue) {
selectElement.children("option:not([" + attributeName + "='" + attributeValue + "'],:not([" + attributeName + "]))").remove();
}
}
}
This little gem tracks the current filter, if different it restores the original select (all items) and then removes the filtered items. If the filter item is empty we see all items.
You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to
table.Variable2 LIKE '%' || :VarB || '%'
and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.
You could also change the Sql to
table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'
You might also find it useful to know generally what these data types are used for:
:string
- is for small data types such as a title. (Should you choose string or text?):text
- is for longer pieces of textual data, such as a paragraph of information:binary
- is for storing data such as images, audio, or movies.:boolean
- is for storing true or false values.:date
- store only the date:datetime
- store the date and time into a column. :time
- is for time only:timestamp
- for storing date and time into a column.(What's the difference between datetime and timestamp?):decimal
- is for decimals (example of how to use decimals).:float
- is for decimals. (What's the difference between decimal and float?):integer
- is for whole numbers.:primary_key
- unique key that can uniquely identify each row in a tableThere's also references used to create associations. But, I'm not sure this is an actual data type.
New Rails 4 datatypes available in PostgreSQL:
:hstore
- storing key/value pairs within a single value (learn more about this new data type):array
- an arrangement of numbers or strings in a particular row (learn more about it and see examples):cidr_address
- used for IPv4 or IPv6 host addresses:inet_address
- used for IPv4 or IPv6 host addresses, same as cidr_address but it also accepts values with nonzero bits to the right of the netmask:mac_address
- used for MAC host addressesLearn more about the address datatypes here and here.
Also, here's the official guide on migrations: http://edgeguides.rubyonrails.org/migrations.html
You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.
You should be doing something more like this:
class MyClassTest
{
[TestMethod]
public void MyMethodTest()
{
string action = "test";
Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();
mockSomeClass.Setup(mock => mock.DoSomething());
MyClass myClass = new MyClass(mockSomeClass.Object);
myClass.MyMethod(action);
// Explicitly verify each expectation...
mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());
// ...or verify everything.
// mockSomeClass.VerifyAll();
}
}
In other words, you are verifying that calling MyClass#MyMethod
, your class will definitely call SomeClass#DoSomething
once in that process. Note that you don't need the Times
argument; I was just demonstrating its value.
Think like this:
class Animal { /* Some virtual members */ };
class Dog: public Animal {};
class Cat: public Animal {};
Dog dog;
Cat cat;
Animal& AnimalRef1 = dog; // Notice no cast required. (Dogs and cats are animals).
Animal& AnimalRef2 = cat;
Animal* AnimalPtr1 = &dog;
Animal* AnimlaPtr2 = &cat;
Cat& catRef1 = dynamic_cast<Cat&>(AnimalRef1); // Throws an exception AnimalRef1 is a dog
Cat* catPtr1 = dynamic_cast<Cat*>(AnimalPtr1); // Returns NULL AnimalPtr1 is a dog
Cat& catRef2 = dynamic_cast<Cat&>(AnimalRef2); // Works
Cat* catPtr2 = dynamic_cast<Cat*>(AnimalPtr2); // Works
// This on the other hand makes no sense
// An animal object is not a cat. Therefore it can not be treated like a Cat.
Animal a;
Cat& catRef1 = dynamic_cast<Cat&>(a); // Throws an exception Its not a CAT
Cat* catPtr1 = dynamic_cast<Cat*>(&a); // Returns NULL Its not a CAT.
Now looking back at your first statement:
Animal animal = cat; // This works. But it slices the cat part out and just
// assigns the animal part of the object.
Cat bigCat = animal; // Makes no sense.
// An animal is not a cat!!!!!
Dog bigDog = bigCat; // A cat is not a dog !!!!
You should very rarely ever need to use dynamic cast.
This is why we have virtual methods:
void makeNoise(Animal& animal)
{
animal.DoNoiseMake();
}
Dog dog;
Cat cat;
Duck duck;
Chicken chicken;
makeNoise(dog);
makeNoise(cat);
makeNoise(duck);
makeNoise(chicken);
The only reason I can think of is if you stored your object in a base class container:
std::vector<Animal*> barnYard;
barnYard.push_back(&dog);
barnYard.push_back(&cat);
barnYard.push_back(&duck);
barnYard.push_back(&chicken);
Dog* dog = dynamic_cast<Dog*>(barnYard[1]); // Note: NULL as this was the cat.
But if you need to cast particular objects back to Dogs then there is a fundamental problem in your design. You should be accessing properties via the virtual methods.
barnYard[1]->DoNoiseMake();
You can simply use fetch with the cache option set to 'reload'
to update the cache:
fetch("my-image-url.jpg", {cache: 'reload', mode: 'no-cors'})
These days the fetch API is available almost everywhere (except on IE, of course).
As always you will find detailed information on how to use the fetch API on MDN.
It's possible to use a udev rule to let the system decide on the scheduler based on some characteristics of the hw.
An example udev rule for SSDs and other non-rotational drives might look like
# set noop scheduler for non-rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="noop"
inside a new udev rules file (e.g., /etc/udev/rules.d/60-ssd-scheduler.rules
). This answer is based on the debian wiki
To check whether ssd disks would use the rule, it's possible to check for the trigger attribute in advance:
for f in /sys/block/sd?/queue/rotational; do printf "$f "; cat $f; done
By using CHMOD yes:
For Recursive file:
chmod -R 777 foldername or pathname
For non recursive:

There are many ways of solving this problem, and the ones listed above are the most commonly used ways of achieving the solution. I want to add two more ways, just in case someone is looking for an alternative.
index_list = [1,3]

df.query('index in @index_list')
I guess ssh
is the best secured way for this, for example :
ssh -OPTIONS -p SSH_PORT user@remote_server "remote_command1; remote_command2; remote_script.sh"
where the OPTIONS have to be deployed according to your specific needs (for example, binding to ipv4 only) and your remote command could be starting your tomcat daemon.
Note:
If you do not want to be prompt at every ssh run, please also have a look to ssh-agent, and optionally to keychain
if your system allows it. Key is... to understand the ssh keys exchange process. Please take a careful look to ssh_config (i.e. the ssh client config file) and sshd_config (i.e. the ssh server config file). Configuration filenames depend on your system, anyway you'll find them somewhere like /etc/sshd_config
. Ideally, pls do not run ssh as root obviously but as a specific user on both sides, servers and client.

Try using
git reset --hard <commit id>
Please Note : Here commit id will the id of the commit you want to go to but not the id you want to reset. this was the only point where i also got stucked.
then push
git push -f <remote> <branch>
Hope this Helps:
public String getSystemTimeInBelowFormat() {
String timestamp = new SimpleDateFormat("yyyy-mm-dd 'T' HH:MM:SS.mmm-HH:SS").format(new Date());
return timestamp;
}
Another interesting approach would be to use when
:
when(a) {
true -> b
false -> c
}
Can be quite handy in some more complex scenarios. And honestly, it's more readable for me than if ... else ...
DateTime values should be inserted as if they are strings surrounded by single quotes
'20201231'
but in many cases they need to be casted explicitly to datetime CAST(N'20201231' AS DATETIME)
to avoid bad execution plans with CONVERSION_IMPLICIT warnings that affect negatively the performance. Hier is an example:
CREATE TABLE dbo.T(D DATETIME)
--wrong way
INSERT INTO dbo.T (D) VALUES ('20201231'), ('20201231')
--better way
INSERT INTO dbo.T (D) VALUES (CAST(N'20201231' AS DATETIME)), (CAST(N'20201231' AS DATETIME))

python setup.py install
is used to install (typically third party) packages that you're not going to develop/modify/debug yourself.
For your own stuff, you want to first install your package and then be able to frequently edit the code without having to re-install the package every time — and that is exactly what python setup.py develop
does: it installs the package (typically just a source folder) in a way that allows you to conveniently edit your code after it’s installed to the (virtual) environment, and have the changes take effect immediately.
Note that it is highly recommended to use pip install .
(install) and pip install -e .
(developer install) to install packages, as invoking setup.py
directly will do the wrong things for many dependencies, such as pull prereleases and incompatible package versions, or make the package hard to uninstall with pip
.
In my case, I have to run some more steps to build it on RedHat or Centos.
# get system libraries
sudo yum install -y gcc wget
# get stable version and untar it
wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
# build dependencies too!
cd deps
make hiredis jemalloc linenoise lua geohash-int
cd ..
# compile it

# make it globally accesible
sudo cp src/redis-cli /usr/bin/
Close iis express and all the browsers (if the url was opened in any of the browser). Also open the visual studio IDE in admin mode. This has resolved my issue.

All answers are great, but they are talking about adding extension method to a specific type of enum.
What if you want to add a method to all enums like returning an int of current value instead of explicit casting?
public static class EnumExtensions
{
public static int ToInt<T>(this T soure) where T : IConvertible//enum
{
if (!typeof(T).IsEnum)
throw new ArgumentException("T must be an enumerated type");
return (int) (IConvertible) soure;
}
//ShawnFeatherly funtion (above answer) but as extention method
public static int Count<T>(this T soure) where T : IConvertible//enum
{
if (!typeof(T).IsEnum)
throw new ArgumentException("T must be an enumerated type");
return Enum.GetNames(typeof(T)).Length;
}
}
The trick behind IConvertible
is its Inheritance Hierarchy see MDSN

Once you declare the type of a variable, you don't need to cast it to that same type. So you can write a=&b;
. Finally, you declared c
incorrectly. Since you assign it to be the address of a
, where a
is a pointer to int
, you must declare it to be a pointer to a pointer to int
.
#include <stdio.h>
int main(void)
{
int b=10;
int *a=&b;
int **c=&a;
printf("%d", **c);
return 0;
}

If you are using implicit Authentication must have the problem of not being able to find the user_id
I found a way for example:
Access Token = 1506417331.18b98f6.8a00c0d293624ded801d5c723a25d3ec
the User id is 1506417331
would you do a split single seperated by . obtenies to acces token and the first element
Try closing and reopening the file, then press Ctrl+F11
.
Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.
Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.
What's the difference between an RDD's map and mapPartitions method?
The method map converts each element of the source RDD into a single element of the result RDD by applying a function. mapPartitions converts each partition of the source RDD into multiple elements of the result (possibly none).
And does flatMap behave like map or like mapPartitions?
Neither, flatMap works on a single element (as map
) and produces multiple elements of the result (as mapPartitions
).
From the docs:
public Form createNamed(string|FormTypeInterface $type, string $name, mixed $data = null, array $options = array())
mixed $data = null is the default options. So for example I have a field called status and I implemented it as so:
$default = array('Status' => 'pending');
$filter_form = $this->get('form.factory')->createNamedBuilder('filter', 'form', $default)
->add('Status', 'choice', array(
'choices' => array(
'' => 'Please Select...',
'rejected' => 'Rejected',
'incomplete' => 'Incomplete',
'pending' => 'Pending',
'approved' => 'Approved',
'validated' => 'Validated',
'processed' => 'Processed'
)
))->getForm();
When converting datetime to integers one must keep in mind the tens, hundreds and thousands.... like "2018-11-03" must be like 20181103 in int for that you have to 2018*10000 + 100* 11 + 3
Similarly another example, "2018-11-03 10:02:05" must be like 20181103100205 in int
dt = datetime(2018,11,3,10,2,5)
print (dt)
#print (dt.timestamp()) # unix representation ... not useful when converting to int
print (dt.strftime("%Y-%m-%d"))
print (dt.year*10000 + dt.month* 100 + dt.day)
print (int(dt.strftime("%Y%m%d")))
print (dt.strftime("%Y-%m-%d %H:%M:%S"))
print (dt.year*10000000000 + dt.month* 100000000 +dt.day * 1000000 + dt.hour*10000 + dt.minute*100 + dt.second)
print (int(dt.strftime("%Y%m%d%H%M%S")))
To avoid that doing manually use below function
def datetime_to_int(dt):
return int(dt.strftime("%Y%m%d%H%M%S"))
This worked for me. Each month on X axis
str_month_list = ['January','February','March','April','May','June','July','August','September','October','November','December']
ax.set_xticks(range(0,12))
ax.set_xticklabels(str_month_list)
find -execdir rename
This renames files and directories with a regular expression affecting only basenames.
So for a prefix you could do:
PATH=/usr/bin find . -depth -execdir rename 's/^/Unix_/' '{}' \;
or to affect files only:
PATH=/usr/bin find . -type f -execdir rename 's/^/Unix_/' '{}' \;
-execdir
first cd
s into the directory before executing only on the basename.
I have explained it in more detail at: Find multiple files and rename them in Linux
TLDR:
CREATE TABLE MyTable(
a int NOT NULL
,b smallint NOT NULL index IX_indexName nonclustered
,c smallint NOT NULL
,d smallint NOT NULL
,e smallint NOT NULL
)
Details
As per T-SQL CREATE TABLE documentation, in 2014 the column definition supports defining an index:
<column_definition> ::=
column_name <data_type>
...
[ <column_index> ]
and <column_index> grammar is defined as:
<column_index> ::=
INDEX index_name [ CLUSTERED | NONCLUSTERED ]
[ WITH ( <index_option> [ ,... n ] ) ]
[ ON { partition_scheme_name (column_name )
| filegroup_name
| default
}
]
[ FILESTREAM_ON { filestream_filegroup_name | partition_scheme_name | "NULL" } ]
So a lot of what you can do as a separate statement can be done inline. I noticed include
is not an option in this grammar so some things are not possible.
CREATE TABLE MyTable(
a int NOT NULL
,b smallint NOT NULL index IX_indexName nonclustered
,c smallint NOT NULL
,d smallint NOT NULL
,e smallint NOT NULL
)
You can also have inline indexes defined as another line after columns, but within the create table statement, and this allows multiple columns in the index, but still no include
clause:
< table_index > ::=
{
{
INDEX index_name [ CLUSTERED | NONCLUSTERED ]
(column_name [ ASC | DESC ] [ ,... n ] )
| INDEX index_name CLUSTERED COLUMNSTORE
| INDEX index_name [ NONCLUSTERED ] COLUMNSTORE (column_name [ ,... n ] )
}
[ WITH ( <index_option> [ ,... n ] ) ]
[ ON { partition_scheme_name (column_name )
| filegroup_name
| default
}
]
[ FILESTREAM_ON { filestream_filegroup_name | partition_scheme_name | "NULL" } ]
}
For example here we add an index on both columns c and d:
CREATE TABLE MyTable(
a int NOT NULL
,b smallint NOT NULL index IX_MyTable_b nonclustered
,c smallint NOT NULL
,d smallint NOT NULL
,e smallint NOT NULL
,index IX_MyTable_c_d nonclustered (c,d)
)
I found the easiest way is using str(timedelta)
. It will return a sting formatted like 3 days, 21:06:40.001000
, and you can parse hours and minutes using simple string operations or regular expression.

If your Rails version is between > 3.1.0
and < 4
, place your fonts in any of the these folders:
app/assets/fonts
lib/assets/fonts
vendor/assets/fonts
For Rails versions > 4
, you must place your fonts in the app/assets/fonts
folder.
Note: To place fonts outside of these designated folders, use the following configuration:
config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/
For Rails versions > 4.2
, it is recommended to add this configuration to config/initializers/assets.rb
.
However, you can also add it to either config/application.rb
, or to config/production.rb
Declare your font in your CSS file:
@font-face {
font-family: 'Icomoon';
src:url('icomoon.eot');
src:url('icomoon.eot?#iefix') format('embedded-opentype'),
url('icomoon.svg#icomoon') format('svg'),
url('icomoon.woff') format('woff'),
url('icomoon.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
Make sure your font is named exactly the same as in the URL portion of the declaration. Capital letters and punctuation marks matter. In this case, the font should have the name icomoon
.
If you are using Sass or Less with Rails > 3.1.0
(your CSS file has .scss
or .less
extension), then change the url(...)
in the font declaration to font-url(...)
.
Otherwise, your CSS file should have the extension .css.erb
, and the font declaration should be url('<%= asset_path(...) %>')
.
If you are using Rails > 3.2.1
, you can use font_path(...)
instead of asset_path(...)
. This helper does exactly the same thing but it's more clear.
Finally, use your font in your CSS like you declared it in the font-family
part. If it was declared capitalized, you can use it like this:
font-family: 'Icomoon';
You can echo
a string, but catch it by piping (|
) the function to something else.
You can do it with expr
, though ShellCheck reports this usage as deprecated.
what's the problem with:
field like "*AA*" and field not like "*BB*"
it should be working.
Could you post some example of your data?
I was getting this error while was presenting controller after the user opens the deeplink.
I know this isn't the best solution, but if you are in short time frame here is a quick fix - just wrap your code in asyncAfter
:
DispatchQueue.main.asyncAfter(deadline: .now() + 0.7, execute: { [weak self] in
navigationController.present(signInCoordinator.baseController, animated: animated, completion: completion)
})
It will give time for your presenting controller to call viewDidAppear
.
One possible cause of the error is the inexistence of the setting of the value of the parent entity ; for example for a department-employees relationship you have to write this in order to fix the error :
Department dept = (Department)session.load(Department.class, dept_code); // dept_code is from the jsp form which you get in the controller with @RequestParam String department
employee.setDepartment(dept);
You didn't tell us what particular problem do you have with the WinSCP, so I can really only repeat what's in WinSCP documentation.
Download WinSCP .NET assembly.
The latest package as of now is WinSCP-5.17.10-Automation.zip
;
Extract the .zip
archive along your script;
Use a code like this (based on the official PowerShell upload example):
# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"
# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
Protocol = [WinSCP.Protocol]::Sftp
HostName = "example.com"
UserName = "user"
Password = "mypassword"
SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
}
$session = New-Object WinSCP.Session
try
{
# Connect
$session.Open($sessionOptions)
# Upload
$session.PutFiles("C:\FileDump\export.txt", "/Outbox/").Check()
}
finally
{
# Disconnect, clean up
$session.Dispose()
}
You can have WinSCP generate the PowerShell script for the upload for you:
You will get a code like above with all session and transfer settings filled in.

TLDR: do not append items to a series one by one, better extend with an ordered collection
I think the question in its current form is a bit tricky. And the accepted answer does answer the question. But the more I use pandas, the more I understand that it's a bad idea to append items to a Series one by one. I'll try to explain why for pandas beginners.
You might think that appending data to a given Series might allow you to reuse some resources, but in reality a Series is just a container that stores a relation between an index and a values array. Each is a numpy.array under the hood, and the index is immutable. When you add to Series an item with a label that is missing in the index, a new index with size n+1 is created, and a new values values array of the same size. That means that when you append items one by one, you create two more arrays of the n+1 size on each step.
By the way, you can not append a new item by position (you will get an IndexError) and the label in an index does not have to be unique, that is when you assign a value with a label, you assign the value to all existing items with the the label, and a new row is not appended in this case. This might lead to subtle bugs.
The moral of the story is that you should not append data one by one, you should better extend with an ordered collection. The problem is that you can not extend a Series inplace. That is why it is better to organize your code so that you don't need to update a specific instance of a Series by reference.
If you create labels yourself and they are increasing, the easiest way is to add new items to a dictionary, then create a new Series from the dictionary (it sorts the keys) and append the Series to an old one. If the keys are not increasing, then you will need to create two separate lists for the new labels and the new values.
Below are some code samples:
In [1]: import pandas as pd
In [2]: import numpy as np
In [3]: s = pd.Series(np.arange(4)**2, index=np.arange(4))
In [4]: s
Out[4]:
0 0
1 1
2 4
3 9
dtype: int64
In [6]: id(s.index), id(s.values)
Out[6]: (4470549648, 4470593296)
When we update an existing item, the index and the values array stay the same (if you do not change the type of the value)
In [7]: s[2] = 14
In [8]: id(s.index), id(s.values)
Out[8]: (4470549648, 4470593296)
But when you add a new item, a new index and a new values array is generated:
In [9]: s[4] = 16
In [10]: s
Out[10]:
0 0
1 1
2 14
3 9
4 16
dtype: int64
In [11]: id(s.index), id(s.values)
Out[11]: (4470548560, 4470595056)
That is if you are going to append several items, collect them in a dictionary, create a Series, append it to the old one and save the result:
In [13]: new_items = {item: item**2 for item in range(5, 7)}
In [14]: s2 = pd.Series(new_items)
In [15]: s2 # keys are guaranteed to be sorted!
Out[15]:
5 25
6 36
dtype: int64
In [16]: s = s.append(s2); s
Out[16]:
0 0
1 1
2 14
3 9
4 16

On MacOS: add source ~/.bash_profile

.
Then this profile will be in effect when you open zsh.
All you have to do is this
list = ["a", "b", "c"]
try:
list.remove("a")
except:
print("meow")
but that method has an issue. You have to put something in the except place so i found this:
list = ["a", "b", "c"]
if "a" in str(list):
list.remove("a")
You can use vh
in this case which is relative to 1% of the height of the viewport...
That means if you want to cover off the height, just simply use 100vh
.
Look at the image below I draw for you here:
Try the snippet I created for you as below:
.left {_x000D_
height: 100vh;_x000D_
width: 50%;_x000D_
background-color: grey;_x000D_
float: left;_x000D_
}_x000D_
_x000D_
.right {_x000D_
height: 100vh;_x000D_
width: 50%;_x000D_
background-color: red;_x000D_
float: right;_x000D_
}
_x000D_
<div class="left"></div>_x000D_
<div class="right"></div>
_x000D_
The simplest solution is to use a derived table:
Select Count(*)
From (
Select ...
From TempTable
Group By column_1, column_2, column_3, column_4
) As Z
Another solution is to use a Count Distinct:
Select ...
, ( Select Count( Distinct column_1, column_2, column_3, column_4 )
From TempTable ) As CountOfItems
From TempTable
Group By column_1, column_2, column_3, column_4
In Kotlin you can create extension property:
inline var TextView.underline: Boolean
set(visible) {
paintFlags = if (visible) paintFlags or Paint.UNDERLINE_TEXT_FLAG
else paintFlags and Paint.UNDERLINE_TEXT_FLAG.inv()
}
get() = paintFlags and Paint.UNDERLINE_TEXT_FLAG == Paint.UNDERLINE_TEXT_FLAG
And use:
textView.underline = true
I had the same issue and found a unique solution. This is not best practice, but it may prove simple/helpful for someone. Just use jquery on the id or class or your select tag and you then have access to both the text and the value in the change function. In my case I'm passing in option values via sails/ejs:
<select id="projectSelector" class="form-control" ng-model="ticket.project.id" ng-change="projectChange(ticket)">
<% _.each(projects, function(project) { %>
<option value="<%= project.id %>"><%= project.title %></option>
<% }) %>
</select>
Then in my Angular controller my ng-change function looks like this:
$scope.projectChange = function($scope) {
$scope.project.title=$("#projectSelector option:selected").text();
};
Path.GetFileName( Request.Url.AbsolutePath )
It's simple, use $.getJSON()
function and in your URL just include
callback=?
as a parameter. That will convert the call to JSONP which is necessary to make cross-domain calls. More info: http://api.jquery.com/jQuery.getJSON/
I prefer to return the identity value as an output parameter. The result of the SP should indicate whether it succeeded or not. A value of 0 indicates the SP successfully completed, a non-zero value indicates an error. Also, if you ever need to make a change and return an additional value from the SP you don't need to make any changes other than adding an additional output parameter.

I am trying to parse JSON data returned from an ajax call, and the following is working for me:
Sample PHP code
$portfolio_array= Array('desc'=>'This is test description1','item1'=>'1.jpg','item2'=>'2.jpg');
echo json_encode($portfolio_array);
And in the .js, i am parsing like this:
var req=$.post("json.php", { id: "" + id + ""},
function(data) {
data=$.parseJSON(data);
alert(data.desc);
$.each(data, function(i,item){
alert(item);
});
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});
If you have multidimensional array like below
$portfolio_array= Array('desc'=>'This is test description 1','items'=> array('item1'=>'1.jpg','item2'=>'2.jpg'));
echo json_encode($portfolio_array);
Then the code below should work:
var req=$.post("json.php", { id: "" + id +
function(data) {
data=$.parseJSON(data);
alert(data.desc);
$.each(data.items, function(i,item){
alert(item);
});
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});
Please note the sub array key here is items, and suppose if you have xyz
then in place of data.items
use data.xyz
I had almost the same example as you in this notebook where I wanted to illustrate the usage of an adjacent module's function in a DRY manner.
My solution was to tell Python of that additional module import path by adding a snippet like this one to the notebook:
import os
import sys
module_path = os.path.abspath(os.path.join('..'))
if module_path not in sys.path:
sys.path.append(module_path)
This allows you to import the desired function from the module hierarchy:
from project1.lib.module import function
# use the function normally
function(...)
Note that it is necessary to add empty __init__.py
files to project1/ and lib/ folders if you don't have them already.
It seems as though gradle was not installed for me. Going to Android/Sdk/tools/templates/gradle/wrapper
and running ./gradlew tasks --debug
has resulted in it downloading.
This will capture requests for files like version
,
release
, and README.md
, etc. which should be
treated either as endpoints, if defined (as in the
case of /release), or as "not found."
From perlfaq8:
How do I add the directory my program lives in to the module/library search path?
(contributed by brian d foy)
If you know the directory already, you can add it to @INC as you would for any other directory. You might use lib if you know the directory at compile time:
use lib $directory;
The trick in this task is to find the directory. Before your script does anything else (such as a chdir), you can get the current working directory with the Cwd module, which comes with Perl:
BEGIN {
use Cwd;
our $directory = cwd;
}
use lib $directory;
You can do a similar thing with the value of $0, which holds the script name. That might hold a relative path, but rel2abs can turn it into an absolute path. Once you have the
BEGIN {
use File::Spec::Functions qw(rel2abs);
use File::Basename qw(dirname);
my $path = rel2abs( $0 );
our $directory = dirname( $path );
}
use lib $directory;
The FindBin module, which comes with Perl, might work. It finds the directory of the currently running script and puts it in $Bin, which you can then use to construct the right library path:
use FindBin qw($Bin);
request.getParameter("accountID")
is what you're looking for. This is part of the Java Servlet API. See http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletRequest.html for more information.
I was having alot of trouble with this because I was using:
if($.cookie('token') === null || $.cookie('token') === "")
{
//no cookie
}
else
{
//have cookie
}
The above was ALWAYS returning false, no matter what I did in terms of setting the cookie or not. From my tests it seems that the object is therefore undefined before it's set so adding the following to my code fixed it.
if($.cookie('token') === null || $.cookie('token') === ""
|| $.(cookie('token') === "null" || $.cookie('token') === undefined)
{
//no cookie
}
else
{
//have cookie
}
This combination of the above answers solved the problem for me:
performed the Java update:
sudo apt-get install default-jdk
then killed the Arduino IDE and restarted it
my correct board now showed up (Arduino Mega 2560, where before Mega 1280 was only option)
for the drivers, I did this:
sudo chmod a+rw /dev/serial/by-id/usb-Arduino__www.arduino.cc__(a bunch of numbers)
After that, my Arduino IDE shows /dev/ttyACM0
in the tools/serial port menu.
Now, everything works great!
A PIL only solution for creating a bi-level (black and white) image with a custom threshold:
from PIL import Image
img = Image.open('mB96s.png')
thresh = 200
fn = lambda x : 255 if x > thresh else 0
r = img.convert('L').point(fn, mode='1')
r.save('foo.png')
With just
r = img.convert('1')
r.save('foo.png')
you get a dithered image.
From left to right the input image, the black and white conversion result and the dithered result:
You can click on the images to view the unscaled versions.
You can directly plot the lines you want by feeding the plot
command with the corresponding data (boundaries of the segments):
plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)
(of course you can choose the color, line width, line style, etc.)
From your example:
import numpy as np
import matplotlib.pyplot as plt
np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")
# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)
# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')
plt.show()
Syntax is as same as of class in C++. If you aware of creating constructor in c++ then it is same in struct.
struct Date
{
int day;
Date(int d)
{
day = d;
}
void printDay()
{
cout << "day " << day << endl;
}
};
Struct can have all things as class in c++. As earlier said difference is only that by default C++ member have private access but in struct it is public.But as per programming consideration Use the struct keyword for data-only structures. Use the class keyword for objects that have both data and functions.
I think your issue may be in the url pattern. Changing
<servlet-mapping>
<servlet-name>Register</servlet-name>
<url-pattern>/Register</url-pattern>
</servlet-mapping>
and
<form action="/Register" method="post">
may fix your problem
You can use the following below with document.title = 'Home Page'
import React from 'react'
import { Component } from 'react-dom'
class App extends Component{
componentDidMount(){
document.title = "Home Page"
}
render(){
return(
<p> Title is now equal to Home Page </p>
)
}
}
ReactDOM.render(
<App />,
document.getElementById('root')
);
or You can use this npm package npm i react-document-title
import React from 'react'
import { Component } from 'react-dom'
import DocumentTitle from 'react-document-title';
class App extends Component{
render(){
return(
<DocumentTitle title='Home'>
<h1>Home, sweet home.</h1>
</DocumentTitle>
)
}
}
ReactDOM.render(
<App />,
document.getElementById('root')
);
Happy Coding!!!
if your are using ES5 syntax then you need to bind it properly
this.delta = this.delta.bind(this)
and if you are using ES6 and above you can use arrow function, then you don't need to use bind() it
delta = () => {
// do something
}
The basic distinction, though, is that functional tests test the application from the outside, from the point of view of the user. Unit tests test the application from the inside, from the point of view of the programmer. Functional tests should help you build an application with the right functionality, and guarantee you never accidentally break it. Unit tests should help you to write code that’s clean and bug free.
Taken from "Python TDD" book by Harry Percival
var now = DateTime.Now;
var first = new DateTime(now.Year, now.Month, 1);
var last = first.AddMonths(1).AddDays(-1);
You could also use DateTime.DaysInMonth
method:
var last = new DateTime(now.Year, now.Month, DateTime.DaysInMonth(now.Year, now.Month));
You can display it like this:
var strOriginal = richTextBox1.Text;
byte[] byt = System.Text.Encoding.ASCII.GetBytes(strOriginal);
// convert the byte array to a Base64 string
string strModified = Convert.ToBase64String(byt);
richTextBox1.Text = "" + strModified;
Now, converting it back.
var base64EncodedBytes = System.Convert.FromBase64String(richTextBox1.Text);
richTextBox1.Text = "" + System.Text.Encoding.ASCII.GetString(base64EncodedBytes);
MessageBox.Show("Done Converting! (ASCII from base64)");
I hope this helps!
I have done with below single git command:
git clone [url] -b [branch-name] --single-branch
You might wanna use include method in JS.
var sentence = "This is my line";
console.log(sentence.includes("my"));
//returns true if substring is present.
PS: includes is case sensitive.
For pandas 0.17 and above, use this :
test = df.sort_values('one', ascending=False)
Since 'one' is a series in the pandas data frame, hence pandas will not accept the arguments in the form of a list.
Solution :
1). Delete the C:\Users\username.gradle folder
2). Download http://downloads.gradle.org/distributions/gradle-2.2.1-all.zip
3). Create a new project in android studio.
4). When this time it stucks at gradle building, Force close the android studio.
5) Now go to C:\Users\username.gradle\wrapper\dists\gradle-2.2.1-all\c64ydeuardnfqctvr1gm30w53 (the end directory name may be different)
6) Delete gradle-2.2.1-all.zip.lck and other files from this directory.
7) Paste the new downloaded gradle-2.2.1-all.zip here.
8) Run the android studio. :)

I ported this plugin to GWT recently since I didn't want to add jquery as a dependency just for using the plugin. Here's my (simple) port (just including the functionality that I need for my use case):
public static boolean isVisible(Element e)
{
//vp = viewPort, b = bottom, l = left, t = top, r = right
int vpWidth = Window.getClientWidth();
int vpHeight = Window.getClientHeight();
boolean tViz = ( e.getAbsoluteTop() >= 0 && e.getAbsoluteTop()< vpHeight);
boolean bViz = (e.getAbsoluteBottom() > 0 && e.getAbsoluteBottom() <= vpHeight);
boolean lViz = (e.getAbsoluteLeft() >= 0 && e.getAbsoluteLeft() < vpWidth);
boolean rViz = (e.getAbsoluteRight() > 0 && e.getAbsoluteRight() <= vpWidth);
boolean vVisible = tViz && bViz;
boolean hVisible = lViz && rViz;
return hVisible && vVisible;
}
Make sure to target x86 on your project in Visual Studio. This should fix your trouble.
I usually use information_Schema.columns
and information_schema.tables
, although like @yuck said, sys.tables
and sys.columns
are shorter to type.
In a loop, concatenate these
@sql = @sql + 'select' + column_name +
' from ' + table_name +
' where ' + column_name ' like ''%''+value+''%' UNION
Then execute the resulting sql.
SELECT o.OrderID
CASE WHEN o.NegotiatedPrice > o.SuggestedPrice THEN
o.NegotiatedPrice
ELSE
o.SuggestedPrice
END AS Price
That is the function that I used for my project, and it works as expected.
function array_csv_download( $array, $filename = "export.csv", $delimiter=";" )
{
header( 'Content-Type: application/csv' );
header( 'Content-Disposition: attachment; filename="' . $filename . '";' );
// clean output buffer
ob_end_clean();
$handle = fopen( 'php://output', 'w' );
// use keys as column titles
fputcsv( $handle, array_keys( $array['0'] ) );
foreach ( $array as $value ) {
fputcsv( $handle, $value , $delimiter );
}
fclose( $handle );
// flush buffer
ob_flush();
// use exit to get rid of unexpected output afterward
exit();
}
Exceptions in the finally block supersede exceptions in the catch block.
If the catch block completes abruptly for reason R, then the finally block is executed. Then there is a choice:
If the finally block completes normally, then the try statement completes abruptly for reason R.
If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S (and reason R is discarded).
Try this one
String str = "This is String";
String[] splited = str.split("\\s+");
String split_one=splited[0];
String split_second=splited[1];
String split_three=splited[2];
Log.d("Splited String ", "Splited String" + split_one+split_second+split_three);
Finally I could successfully compile a program with C++ connector in Ubuntu 12.04 I have installed the connector using this command
'apt-get install libmysqlcppconn-dev'
Initially I faced the same problem with "undefined reference to `get_driver_instance' " to solve this I declare my driver instance variable of MySQL_Driver type. For ready reference this type is defined in mysql_driver.h file. Here is the code snippet I used in my program.
sql::mysql::MySQL_Driver *driver;
try {
driver = sql::mysql::get_driver_instance();
}
and I compiled the program with -l mysqlcppconn linker option
and don't forget to include this header
#include "mysql_driver.h"
sudo vim /etc/apache2/httpd.conf
ServerName localhost
sudo /etc/init.d/apache2 restart
The main use of -f
is to force the removal of files that would
not be removed using rm
by itself (as a special case, it "removes"
non-existent files, thus suppressing the error message).
You can also just redirect the error message using
$ rm file.txt 2> /dev/null
(or your operating system's equivalent). You can check the value of $?
immediately after calling rm
to see if a file was actually removed or not.
You can return a List
instead of an array and things gets much simpler.
public static List<File> listf(String directoryName) {
File directory = new File(directoryName);
List<File> resultList = new ArrayList<File>();
// get all the files from a directory
File[] fList = directory.listFiles();
resultList.addAll(Arrays.asList(fList));
for (File file : fList) {
if (file.isFile()) {
System.out.println(file.getAbsolutePath());
} else if (file.isDirectory()) {
resultList.addAll(listf(file.getAbsolutePath()));
}
}
//System.out.println(fList);
return resultList;
}
The code:
public class Test {
public static void main(String args[]) {
String string = args[0];
System.out.println("last character: " +
string.substring(string.length() - 1));
}
}
The output of java Test abcdef
:
last character: f
This function supports:

I know that is a old question, but...
You can also use this in your class:
@Autowired
private HttpServletRequest context;
And this will provide the current instance of HttpServletRequest
for you use on your method.
You have to call close()
on the GZIPOutputStream
before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush()
probably won't help ... though calling finish()
instead of close()
should work. Look at the javadocs.)
Here's the correct code (in Java);
package test;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class GZipTest {
public static void main(String[] args) throws
FileNotFoundException, IOException {
String name = "/tmp/test";
GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
gz.write(10);
gz.close(); // Remove this to reproduce the reported bug
System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
}
}
(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)
$("#ValuationName").bind("keypress", function (event) {
if (event.charCode!=0) {
var regex = new RegExp("^[a-zA-Z ]+$");
var key = String.fromCharCode(!event.charCode ? event.which : event.charCode);
if (!regex.test(key)) {
event.preventDefault();
return false;
}
}
});
The latest PowerShell version as of Sept 2015 is PowerShell 4.0. It's bundled with Windows Management Framework 4.0.
Here's the download page for PowerShelll 4.0 for all versions of Windows. For Windows 7, there are 2 links on that page, 1 for x64 and 1 for x86.
Often used with/as a part of OOAD and business modeling. The definition by Neil is correct, but it is basically identical to MVC, but just abstracted for the business. The "Good summary" is well done so I will not copy it here as it is not my work, more detailed but inline with Neil's bullet points.
You can also use this function,
function optionDisable(selectId, optionIndices)
{
for (var idxCount=0; idxCount<optionIndices.length;idxCount++)
{
document.getElementById(selectId).children[optionIndices[idxCount]].disabled="disabled";
document.getElementById(selectId).children[optionIndices[idxCount]].style.backgroundColor = '#ccc';
document.getElementById(selectId).children[optionIndices[idxCount]].style.color = '#f00';
}
}
-XX:PermSize
specifies the initial size that will be allocated during startup of the JVM. If necessary, the JVM will allocate up to -XX:MaxPermSize
.
I think the java.lang.UnsupportedOperationException
is what you are looking for.
Use an object (key/value pairs, the nearest JavaScript has to an associative array) for this and not the array object. Other than that, I believe that is the most elegant way
var foo = {};
foo['alfa'] = "first item";
foo['beta'] = "second item";
for (var key in foo) {
console.log(key);
}
Note: JavaScript doesn't guarantee any particular order for the properties. So you cannot expect the property that was defined first to appear first, it might come last.
EDIT:
In response to your comment, I believe that this article best sums up the cases for why arrays in JavaScript should not be used in this fashion -
You could use a pass
statement:
if condition:
pass
However I doubt you want to do this, unless you just need to put something in as a placeholder until you come back and write the actual code for the if
statement.
If you have something like this:
if condition: # condition in your case being `num2 == num5`
pass
else:
do_something()
You can in general change it to this:
if not condition:
do_something()
But in this specific case you could (and should) do this:
if num2 != num5: # != is the not-equal-to operator
do_something()
Delete the files from your Explorer view. You see them crossed-out in your Branch view. Then commit and Sync.
Be aware: If files are on your .gitignore list, then the delete "update" will not be pushed and therefore not be visible. VS Code will warn you if this is the case, though. -> Exclude the files/folder from gitignore temporarily.
Using the type="email"
or type="url"
will give you a keyboard on some phones at least, such as iPhone. For phone numbers, you can use type="tel"
.
private void fillTextView (int id, String text) {
TextView tv = (TextView) findViewById(id);
tv.setText(text);
}
If this is where you're getting the null pointer exception, there was no view found for the id that you passed into findViewById()
, and the actual exception is thrown when you try to call a function setText()
on null
. You should post your XML for R.layout.activity_main
, as it's hard to tell where things went wrong just by looking at your code.
More reading on null pointers: What is a NullPointerException, and how do I fix it?
If you want to fake a $_GET (or a $_POST) when including a file, you can use it like you would use any other var, like that:
$_GET['key'] = 'any get value you want';
include('your_other_file.php');
change the port may help as 80 port is already using somewhere
vi /etc/nginx/sites-available/default
Change the port:
listen 8080 default_server;
listen [::]:8080 default_server;
And then restart the nginx server
nginx -t
service nginx restart
The problem with your solution is that it does not work well when tied down to other directives that creates a new scope, e.g. ng-repeat
. A better solution would be to simply create a service function that enables you to focus elements imperatively within your controllers or to focus elements declaratively in the html.
JAVASCRIPT
Service
.factory('focus', function($timeout, $window) {
return function(id) {
// timeout makes sure that it is invoked after any other event has been triggered.
// e.g. click events that need to run before the focus or
// inputs elements that are in a disabled state but are enabled when those events
// are triggered.
$timeout(function() {
var element = $window.document.getElementById(id);
if(element)
element.focus();
});
};
});
Directive
.directive('eventFocus', function(focus) {
return function(scope, elem, attr) {
elem.on(attr.eventFocus, function() {
focus(attr.eventFocusId);
});
// Removes bound events in the element itself
// when the scope is destroyed
scope.$on('$destroy', function() {
elem.off(attr.eventFocus);
});
};
});
Controller
.controller('Ctrl', function($scope, focus) {
$scope.doSomething = function() {
// do something awesome
focus('email');
};
});
HTML
<input type="email" id="email" class="form-control">
<button event-focus="click" event-focus-id="email">Declarative Focus</button>
<button ng-click="doSomething()">Imperative Focus</button>
Not clear where My_ConnectionString
is coming from in your example, but try this
System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString
like this
Dim DBConnection As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString)
When you use append
, jQuery expects it to be well-formed HTML (plain text counts). append
is not like doing +=
.
You need to make the table first, then append it.
var $table = $('<table/>');
for(var i=0; i<3; i++){
$table.append( '<tr><td>' + 'result' + i + '</td></tr>' );
}
$('#here_table').append($table);
React-Router 5.1.0+ Answer (using hooks and React >16.8)
You can use the new useHistory
hook on Functional Components and Programmatically navigate:
import { useHistory } from "react-router-dom";
function HomeButton() {
let history = useHistory();
// use history.push('/some/path') here
};
React-Router 4.0.0+ Answer
In 4.0 and above, use the history as a prop of your component.
class Example extends React.Component {
// use `this.props.history.push('/some/path')` here
};
NOTE: this.props.history does not exist in the case your component was not rendered by <Route>
. You should use <Route path="..." component={YourComponent}/>
to have this.props.history in YourComponent
React-Router 3.0.0+ Answer
In 3.0 and above, use the router as a prop of your component.
class Example extends React.Component {
// use `this.props.router.push('/some/path')` here
};
React-Router 2.4.0+ Answer
In 2.4 and above, use a higher order component to get the router as a prop of your component.
import { withRouter } from 'react-router';
class Example extends React.Component {
// use `this.props.router.push('/some/path')` here
};
// Export the decorated class
var DecoratedExample = withRouter(Example);
// PropTypes
Example.propTypes = {
router: React.PropTypes.shape({
push: React.PropTypes.func.isRequired
}).isRequired
};
React-Router 2.0.0+ Answer
This version is backwards compatible with 1.x so there's no need to an Upgrade Guide. Just going through the examples should be good enough.
That said, if you wish to switch to the new pattern, there's a browserHistory module inside the router that you can access with
import { browserHistory } from 'react-router'
Now you have access to your browser history, so you can do things like push, replace, etc... Like:
browserHistory.push('/some/path')
Further reading: Histories and Navigation
React-Router 1.x.x Answer
I will not go into upgrading details. You can read about that in the Upgrade Guide
The main change about the question here is the change from Navigation mixin to History. Now it's using the browser historyAPI to change route so we will use pushState()
from now on.
Here's an exemple using Mixin:
var Example = React.createClass({
mixins: [ History ],
navigateToHelpPage () {
this.history.pushState(null, `/help`);
}
})
Note that this History
comes from rackt/history project. Not from React-Router itself.
If you don't want to use Mixin for some reason (maybe because of ES6 class), then you can access the history that you get from the router from this.props.history
. It will be only accessible for the components rendered by your Router. So, if you want to use it in any child components it needs to be passed down as an attribute via props
.
You can read more about the new release at their 1.0.x documentation
Here is a help page specifically about navigating outside your component
It recommends grabbing a reference history = createHistory()
and calling replaceState
on that.
React-Router 0.13.x Answer
I got into the same problem and could only find the solution with the Navigation mixin that comes with react-router.
Here's how I did it
import React from 'react';
import {Navigation} from 'react-router';
let Authentication = React.createClass({
mixins: [Navigation],
handleClick(e) {
e.preventDefault();
this.transitionTo('/');
},
render(){
return (<div onClick={this.handleClick}>Click me!</div>);
}
});
I was able to call transitionTo()
without the need to access .context
Or you could try the fancy ES6 class
import React from 'react';
export default class Authentication extends React.Component {
constructor(props) {
super(props);
this.handleClick = this.handleClick.bind(this);
}
handleClick(e) {
e.preventDefault();
this.context.router.transitionTo('/');
}
render(){
return (<div onClick={this.handleClick}>Click me!</div>);
}
}
Authentication.contextTypes = {
router: React.PropTypes.func.isRequired
};
React-Router-Redux
Note: if you're using Redux, there is another project called React-Router-Redux that gives you redux bindings for ReactRouter, using somewhat the same approach that React-Redux does
React-Router-Redux has a few methods available that allow for simple navigating from inside action creators. These can be particularly useful for people that have existing architecture in React Native, and they wish to utilize the same patterns in React Web with minimal boilerplate overhead.
Explore the following methods:
push(location)
replace(location)
go(number)
goBack()
goForward()
Here is an example usage, with Redux-Thunk:
./actioncreators.js
import { goBack } from 'react-router-redux'
export const onBackPress = () => (dispatch) => dispatch(goBack())
./viewcomponent.js
<button
disabled={submitting}
className="cancel_button"
onClick={(e) => {
e.preventDefault()
this.props.onBackPress()
}}
>
CANCEL
</button>
theharshest answered the question but here is another way to do the same thing. Also, In your example you have NAME in caps and in your code you have name in lowercase.
s = '<div class="question" id="get attrs" name="python" x="something">Hello World</div>'
soup = BeautifulSoup(s)
attributes_dictionary = soup.find('div').attrs
print attributes_dictionary
# prints: {'id': 'get attrs', 'x': 'something', 'class': ['question'], 'name': 'python'}
print attributes_dictionary['class'][0]
# prints: question
print soup.find('div').get_text()
# prints: Hello World
If you want force this behaviour on all of your figures try
...
\usepackage{float}
\floatplacement{figure}{H}
...
Sleep() causes the currently executing thread to sleep (temporarily cease execution).
Yield() causes the currently executing thread object to temporarily pause and allow other threads to execute.

In the .NET framework, there are two species of types--value types and reference types. This is relatively common in OO languages.
One of the important features of object oriented languages is the ability to handle instances in a type-agnostic manner. This is referred to as polymorphism. Since we want to take advantage of polymorphism, but we have two different species of types, there has to be some way to bring them together so we can handle one or the other the same way.
Now, back in the olden days (1.0 of Microsoft.NET), there weren't this newfangled generics hullabaloo. You couldn't write a method that had a single argument that could service a value type and a reference type. That's a violation of polymorphism. So boxing was adopted as a means to coerce a value type into an object.
If this wasn't possible, the framework would be littered with methods and classes whose only purpose was to accept the other species of type. Not only that, but since value types don't truly share a common type ancestor, you'd have to have a different method overload for each value type (bit, byte, int16, int32, etc etc etc).
Boxing prevented this from happening. And that's why the British celebrate Boxing Day.

None of the above worked for me because my devices are in a balance-rr bond. Querying either would say the same MAC address with ip l l
, ifconfig
, or /sys/class/net/${device}/address
, so one of them is correct, and one is unknown.
But this works if you haven't renamed the device (any tips on what I missed?):
udevadm info -q all --path "/sys/class/net/${device}"
And this works even if you rename it (eg. ip l set name x0 dev p4p1
):
cat /proc/net/bonding/bond0
or my ugly script that makes it more parsable (untested driver/os/whatever compatibility):
awk -F ': ' '
$0 == "" && interface != "" {
printf "%s %s %s\n", interface, mac, status;
interface="";
mac=""
};
$1 == "Slave Interface" {
interface=$2
};
$1 == "Permanent HW addr" {
mac=$2
};
$1 == "MII Status" {
status=$2
};
END {
printf "%s %s %s\n", interface, mac, status
}' /proc/net/bonding/bond0
Open another terminal window and execute the following commands,
mongodb
use mydb
db.dropDatabase()
Output of that operation shall look like the following
MAC:FOLDER USER$ mongodb
> show databases
local 0.78125GB
mydb 0.23012GB
test 0.23012GB
> use mydb
switched to db mydb
>db.dropDatabase()
{ "dropped" : "mydb", "ok" : 1 }
>
Please note that mydb
is still in use, hence inserting any input at that time will initialize the database again.
return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".
If you are using Toolbar try below code:
toolbar.setTitle("");
You can simply do this in one line solution!
string s = "welcome to london";
s.Replace(" ", "()").Replace(")(", "").Replace("()", " ");
You can choose other brackets (or even other characters) if you like.
item=sp.getItemAtPosition(i).toString();
list.add(item);
adapter.notifyDataSetChanged () ;
I fixed this on my PC, on my environment iReport was iReport-5.1.0 , both jdk 7 and jdk 8 had been installed.
but iReport did not load
fix:- 1. Find the iReport.conf //C:\Program Files (x86)\Jaspersoft\iReport-5.1.0\etc
Open it on text editor
copy your jdk installation path //C:\Program Files (x86)\Java\jdk1.8.0_60
add jdkhome= into the ireport.conf file jdkhome="C:/Program Files (x86)/Java/jdk1.8.0_60"
Now iReport will work
Just updating google-service version did not work for me.
compile
are replaced with implementation
.compile
then your project will show this error. So update all dependencies version.I used a quick work around so I could keep the DropDownList style.

If you use databinding you'll have to create a dummy version of the type you're bound to - just make sure you remove it before any persistence logic.

<div onclick="test('child1')">
Test
<div id="child1">child</div>
</div>
then you just need the test() function to look up the element by id that you passed in.
For RHEL-mysql 5.5:
/etc/init.d/mysql stop
/etc/init.d/mysql start --skip-grant-tables
mysql> UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> exit;
mysql -uroot -pnewpwd
mysql>
It is working form me. Here I am geeting the table created datetime and adding 10 minutes on the datetime. later depending on the current time, Expiry Operations are done.
from datetime import datetime, time, timedelta
import pytz
Added 10 minutes on database datetime
table_datetime = '2019-06-13 07:49:02.832969' (example)
# Added 10 minutes on database datetime
# table_datetime = '2019-06-13 07:49:02.832969' (example)
table_expire_datetime = table_datetime + timedelta(minutes=10 )
# Current datetime
current_datetime = datetime.now()
# replace the timezone in both time
expired_on = table_expire_datetime.replace(tzinfo=utc)
checked_on = current_datetime.replace(tzinfo=utc)
if expired_on < checked_on:
print("Time Crossed)
else:
print("Time not crossed ")
It worked for me.
Escaping a double quote can absolutely be necessary in sed: for instance, if you are using double quotes in the entire sed expression (as you need to do when you want to use a shell variable).
Here's an example that touches on escaping in sed but also captures some other quoting issues in bash:
# cat inventory
PURCHASED="2014-09-01"
SITE="Atlanta"
LOCATION="Room 154"
Let's say you wanted to change the room using a sed script that you can use over and over, so you variablize the input as follows:
# i="Room 101" (these quotes are there so the variable can contains spaces)
This script will add the whole line if it isn't there, or it will simply replace (using sed) the line that is there with the text plus the value of $i.
if grep -q LOCATION inventory; then
## The sed expression is double quoted to allow for variable expansion;
## the literal quotes are both escaped with \
sed -i "/^LOCATION/c\LOCATION=\"$i\"" inventory
## Note the three layers of quotes to get echo to expand the variable
## AND insert the literal quotes
else
echo LOCATION='"'$i'"' >> inventory
fi
P.S. I wrote out the script above on multiple lines to make the comments parsable but I use it as a one-liner on the command line that looks like this:
i="your location"; if grep -q LOCATION inventory; then sed -i "/^LOCATION/c\LOCATION=\"$i\"" inventory; else echo LOCATION='"'$i'"' >> inventory; fi
The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).
WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.
For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:
ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.
Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.
In the scenarios listed below you should go for WCF:
WEB API is a framework for developing RESTful/HTTP services.
There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.
HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.
Following work for me:
Keep following setting blank if you have made in build.gradle.
signingConfigs {
release {
storePassword ""
keyAlias ""
keyPassword ""
}
}
and choose Gradle Task from your Editor window. It will show list of all flavor if you have created.
Here's a way to print progress while cloning a repo with GitPython
import time
import git
from git import RemoteProgress
class CloneProgress(RemoteProgress):
def update(self, op_code, cur_count, max_count=None, message=''):
if message:
print(message)
print('Cloning into %s' % git_root)
git.Repo.clone_from('https://github.com/your-repo', '/your/repo/dir',
branch='master', progress=CloneProgress())
For Laravel, If you insert a new record and call $data->save()
this function executes an INSERT query and returns the primary key value (i.e. id by default).
You can use following code:
if($data->save()) {
return Response::json(array('status' => 1, 'primary_id'=>$data->id), 200);
}
