d7801 | train | Although you should really switch to PDO / mysqli and prepared statements with bound parameters to avoid sql injection and breaking sql statements if your variables contain quotation marks, you will probably run into problems with PDO / mysqli as well: Your password (change it!) contains a $.

d7803 | train | In my opinion, your approach can be improved altogether
*
*Firstly, animating the margin property of an element is not a good way to move it left and right. Making the element fixed and animating the left and right properties would work much better.
*Secondly, you could greatly simplify the code by using an attribute on the button to determine direction instead of writing duplicated code with just a few words different for moving left vs right.
*Also, your calling your variable delay but using that variable to set the animation's duration which is misleading. You should re-name that duration

d7804 | train | Is it size or execution time?
I'm going to assume that self is a UI object. If it is, the block should be:
Controller* __weak weakSelf = self;
dispatch_async(queue, ^{
Controller* strongSelf = weakSelf;

d7805 | train | That topic comes up every once in a while, but the conclusion always has been that this isn't something that the core wants to support: https://github.com/cakephp/cakephp/issues/9197
So you're on your own here, and there's many ways how you could solve this in a more DRY manner, but that depends to a non-negligible degree on your application's specific needs. It's hard to give any proper generic advice on this, as doing things wrong can have dire consequences.
Like if you'd blindly apply a specific connection to all read operations, you'd very likely end up very sad when your application will issue a read on a different connection while you're in a transaction that writes something based on the read data.
All that being sad, you could split your models into read/write ones, going down the CQRS-ish route, you could use behaviors that provide a more straightforward and reusable API for your tables, you could move your operations into the model layer and hide the possibly a bit dirty implementation that way, you could configure the default connection based on the requested endpoint, eg whether it's a read or a write one, etc.
There's many ways to "solve" the problem, but I'm afraid it's not something anyone here could definitively answer.
A: I needed this too, and solved it by extending the Table class to an "AppTable." I overrode the find() method to use a different version of query(), which I called readQuery(). Within my readQuery(), I modified the $_connection member variable to use my read-only connection before generating the query with $this->query(). Then when the query was generated, I switched it back to the write connection. I included checks to make sure I didn't do this if there was an active transaction or if anything had been written previously in the request lifecycle (because the replication might not have finished yet, and I'd get old data).
It wasn't terribly difficult to set up; you just need to be willing to extend Cake's base Table class a bit to switch between the two connections when generating the Query object in find(). | unknown | |

A: Just add notifyDataSetChanged() to your Activity as below:
aQuery.ajax(URL, JSONObject.class,new AjaxCallback<JSONObject>(){
@Override
public void callback(String url, JSONObject object, AjaxStatus status) {
try {
bean = new Bean();
list = new ArrayList<Bean>();
String string = object.getString("data");
JSONArray jsonArray = new JSONArray(string);
for (int i=0;i<jsonArray.length();i++) {
jsonObject = jsonArray.getJSONObject(i);
bean.setPropertyName("property_name");
bean.setPropertyDescription("property_desc");
list.add(bean);
}
//here notify your adapter
//is to Notify any registered observers that the data set has changed.
mAdapter.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
});
A: Because on your callback you have created new instance of list
list = new ArrayList<Bean>();
then in fact, the new created list and DataList in your adapter are pointing to 2 difference objects => calling notifyDataSetChanged here won't work. Try writing method updateData on MyAdapter and call it from your callback method
public void updateData(List<Bean> List){
DataList = List;
notifyDataSetChanged();
}
On your callback:
aQuery.ajax(URL, JSONObject.class,new AjaxCallback<JSONObject>(){
@Override
public void callback(String url, JSONObject object, AjaxStatus status) {
try {
bean = new Bean();
list = new ArrayList<Bean>();
String string = object.getString("data");
JSONArray jsonArray = new JSONArray(string);
for (int i=0;i<jsonArray.length();i++) {
jsonObject = jsonArray.getJSONObject(i);
bean.setPropertyName("property_name");
bean.setPropertyDescription("property_desc");
list.add(bean);
}
// update data
mAdapter.updateData(list);
} catch (JSONException e) {
e.printStackTrace();

With the cursor on `ifdef (or `ifndef), you want to jump to `endif with % then back to `ifdef if you press % again. I'm also assuming you're using the matchit plugin.

While it feels warm and fuzzy to be able to support all browsers, IE6 is not a warm and fuzzy kind of browser. You will keep running into problems if you want to fully support IE6, I'm afraid. | unknown | |
d7811 | train | It isn't clear in this example. But you can not have inline scripts containing <script> or </script> inside of a string, or the browser will try and process it like a script tag.
Escaping and unescaping html avoids this problem. A better solution is to put the script in a separate file from the html document.
A: For xhtml compliance you cannot have any HTML tag (<div></div> or <img />) inside a script block so either you use unescape or concatenation '<' + 'div...' or you add //<![CDATA[ ... //]]> inside the script block to pass validation.
A: Line breaks and similar quotes to the JavaScript's break the parser.
var test = "This "string", for example.";
Backslash escapes are built-in, so this works:
var test = "This \"string\", for example.";
But then you'd have to find a function to escape ", ', \n, \r, and from the other answers, < and > as well.
escape() already encodes strings to remove most non-alphanumeric characters, and unescape() undoes escape().
escape("It's > 20% less complicated this way.")
"It%27s%20%3E%2020%25%20less%20complicated%20this%20way."
If the escaped spaces bother you, try:

Have a look at the form fields' clean methods that you can override on django docs http://docs.djangoproject.com/en/dev/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other
A: Thank you for your code, I've just tested it. But it's not exactly what I'm looking for, I will explain what I want to do.
Let's say that we have Category and Article classes in our model, each one has a title. To make this title reusable, I created another application that will manage fields, I created the class Title and I added it as foreignkey to Category and Article forms.
I switched the select box to an input field using raw_id_fields.
Now, when I create a category or an article, I have to select or write a title, when this title exists, it works perfectly but when it doesn't exist I want to create it before creating the category so it can use it.
I tried to do that in the save method, in the pre_save signal and in the clean method but I always get the error "Select a valid choice. That choice is not one of the available choices."
I'm using a hard coded solution to create the title now, I want just to see if it will work, these are the lines that I inserted in the different methods to create the title before creating the category :
t = Title(title = "MyTitle")
t.save()
I tried to create a Category with MyTitle as title but I get the same error, when I try to create another one using an existing title, it works and the title "MyTitle" is created. That's mean that the creation of the object happens after the form verification. What I want is just doing this before. The title object should be created before the verification.
Thank you very much for your help
A: You should probably consider putting the code to create Category entries in the model's manager:
class CategoryManager(Manager):
def create_category(category, title):
t = Title.objects.get_or_create(title=title)
return self.create(title=t)
class Category(models.Model):
title = models.ForeignKey(Title, verbose_name="Title")
objects = CategoryManager()
Then use create_category every time you want to create a Category. | unknown | |

You have ports D and Q declared as input and output ports of module dff which is ok, but you are trying to use D and Q in firfilter module which doesn't know anything about D and Q from module dff.

module firfilter(
input din,
input clock,
output dout
);
parameter b0 = 1'd1;
parameter b1 = 1'd1;

endmodule
module dff (

input clock,

d7821 | train | There are quite a few ways of doing this, but the easiest way, given the code you have supplied, is just to input the current $_GET['dl'] value. Like so:
<a href="index.php?dc=downloads&sort=id&dl=<?=$_GET['dl']?>" >id</a>
<?=$_GET['dl']?>: This will take the dl value that is currently in the get parameters and place it into your link.
A better method would probably be to check if there is already a dl value in the GET parameters first:
<? if(isset($_GET['dl']) && $_GET['dl'] != ''): ?>
<a href="index.php?dc=downloads&sort=id&dl=<?=$_GET['dl']?>">id</a>
<? else: ?>
<a href="index.php?dc=downloads&sort=id">id</a>

d7822 | train | A for loop has the following structure:
for (initialization; condition; update)
The update is executed after every execution of the loop.
Therefore the following two loops are identical:
for (int i = 0; i < 10; i++) {
and
for (int i = 0; i < 10; ++i) {
A:
my question is should k not be 1 because its been pre-incremented?
The ++k happens at the end of the loop iteration, i.e. after the if statement.
It makes no difference whether it's ++k or k++; in either case the first value of k is zero.
So the answer they give is "Hello-1"
This is clearly incorrect, since counter is never incremented and stays at zero throughout the program.
A: k cannot be 1.
This is because when a for loop runs, it only updates after it has executed all the code within the loop. Since the loop breaks even before the first iteration is completed, k remains 0. | unknown | |
d7823 | train | When you do this:
this.$el.html( this.subView.render().el );
You're effectively saying this:
this.$el.empty();
this.$el.append( this.subView.render().el );
and empty kills the events on everything inside this.$el:
To avoid memory leaks, jQuery removes other constructs such as data and event handlers from the child elements before removing the elements themselves.
So you lose the delegate call that binds events on this.subView and the SubView#render won't rebind them.
You need to slip a this.subView.delegateEvents() call into this.$el.html() but you need it to happen after the empty(). You could do it like this:
render: function(){
console.log( "Composer.render" );
this.$el.empty();
this.subView.delegateEvents();
this.$el.append( this.subView.render().el );
return this;
}
Demo: http://jsfiddle.net/ambiguous/57maA/1/
Or like this:
render: function(){
console.log( "Composer.render" );
this.$el.html( this.subView.render().el );
this.subView.delegateEvents();
return this;
}
Demo: http://jsfiddle.net/ambiguous/4qrRa/
Or you could remove and re-create the this.subView when rendering and sidestep the problem that way (but this might cause other problems...).
A: There's a simpler solution here that doesn't blow away the event registrations in the first place: jQuery.detach().
http://jsfiddle.net/ypG8U/1/
this.subView.render().$el.detach().appendTo( this.$el );
This variation is probably preferable for performance reasons though:
http://jsfiddle.net/ypG8U/2/
this.subView.$el.detach();
this.subView.render().$el.appendTo( this.$el );
// or
this.$el.append( this.subView.render().el );
Obviously this is a simplification that matches the example, where the sub view is the only content of the parent. If that was really the case, you could just re-render the sub view. If there were other content you could do something like:
var children = array[];
this.$el.children().detach();
children.push( subView.render().el );
// ...
this.$el.append( children );
or
_( this.subViews ).each( function ( subView ) {
subView.$el.detach();
} );
// ...
Also, in your original code, and repeated in @mu's answer, a DOM object is passed to jQuery.html(), but that method is only documented as accepting strings of HTML:
this.$el.html( this.subView.render().el );
Documented signature for jQuery.html():
.html( htmlString )
http://api.jquery.com/html/#html2
A: When using $(el).empty() it removes all the child elements in the selected element AND removes ALL the events (and data) that are bound to any (child) elements inside of the selected element (el).
To keep the events bound to the child elements, but still remove the child elements, use:
$(el).children().detach(); instead of $(.el).empty();
This will allow your view to rerender successfully with the events still bound and working. | unknown | |

Because I was using a generic repository pattern and unit of work, I wasn't able to specifically disable it just for that call so I ended up using the context directly and everything behaved properly without disabling needed -- this breaks my pattern, but I now have the benefit of being able to use projection and save my application from eagerly loading unnecessary data columns.
If anyone can point me down the right path for implementing projection in a generic repository, I'd be greatful, but I can live with this alternative solution for now.

d7832 | train | The short answer is, SSO-inside-an-installed-PWA is broken on Chrome for Desktop as of Chrome 70 (November 2018).
The good news is, the W3C web.manifest standard has changed, and will no longer require browsers to open out-of-scope navigation in a separate window. This will fix the case of installed PWAs with single-sign-on authentication. This will be fixed in Chrome 71 on the desktop (due December 2018), and is already fixed on Chrome for Android.
Here's the update to the W3C web.manifest spec that details the change. In short, the spec says browsers must not block out-of-scope navigation inside an installed PWA. Instead, the spec encourages browsers to show some prominent UI (perhaps a bar at the top) notifying the user that the navigation is out-of-scope.
"Unlike previous versions of this specification, user agents are no
longer required or allowed to block off-scope navigations, or open
them in a new top-level browsing context. This practice broke a lot of
sites that navigate to a URL on another origin..." | unknown | |

d7837 | train | In my experience, VS2008 can open VS2010 project files if there aren't VS2010-specific bits in it - so simple class libraries or console apps are fine, for example. There will be a warning that the tools version is unknown, but it will basically work. (You'll still need to target .NET 3.5, I believe - I haven't tried opening a .NET 4 project in VS2008, but I wouldn't really expect it to work, at least not if it uses new language features.)
Where I've used this approach, I've had two different solution files - one for VS2008 and one for VS2010, both including the same projects. That way both can open without any problems, and without any conversion prompts. So far it's worked fine.
As I say, that's my experience - YMMV.
A: I was able to open a project file created in VS2010 by simply opening it in VS2008. I was then able to go into Project Properties and set the target framework - just be sure to check the Build settings too, as 2010 is version 4, which isn't supported in 2008.
In my particular case, I targeted Framework v2.0, which involved removing unused LINQ references. The project compiled happily, and I was able to run the app.
A: No, the project file format has been extended. | unknown | |

d7841 | train | You can't do that for security reasons. Just imagine the possibilities. I enter a file by JavaScript in a hidden field. You press submit. I get your file. Any file. Terrifying, right?
A:
You can not select file in file uploader because of Browser security .
User can only do this not the script .
A: this script already upload the files to the server.. what you need is a way to get back the files name/id from the server and attach them to hidden form.. than when someone submit the form you will know which files he uploaded..
youd do this by listen to the onSuccess event..
A: For security reasons you can not dynamically change the value an input field of type file. If that were possible, a malicious user could set the value to say: "c:\maliciousfile" and harm your system
A: Looks like your question is two-part:
*
*How to dynamically add files to a form using JavaScript
1a. (I'll throw in a bonus - previewing images)
*How to perform an Ajax file upload
1 Dynamically adding files to a form
What you want to do here create an <input type="file"> field and change the form value by Javascript. You can hide the input using CSS display: none;.
As far as I know, this can only be done using the FileReader API and drag and drop, and the API is limited.
You can replace and remove all files from an input but you can't append or remove individual files.
The basic drag/drop file upload looks like this:
const dropZone = document.getElementById('dropzone');
const fileInput = document.getElementById('file-input');
dropzone.addEventListener('dragover', event => {
// we must preventDefault() to let the drop event fire
event.preventDefault();
});
dropzone.addEventListener('drop', event => {
event.preventDefault();
// drag/drop files are in event.dataTransfer
let files = event.dataTransfer.files;
fileInput.files = files;
console.log(`added ${files.length} files`);
});
.upload {
border: 1px solid #eee;
border-radius: 10px;
padding: 20px
}
.hidden {
opacity: 0.5;
}
<div id="dropzone" class="upload">Drop images here</div>
<input type="file" id="file-input" class="hidden" />
1a Previewing files
Working with Javascript opens up some fun options for form interactions, such as previewing uploaded files. Take for example an image uploader which can preview multiple drag-and-dropped images.
const imageTypeFilter = /image.*/;
const dropZone = document.getElementById('dropzone');
const fileInput = document.getElementById('file-input');
const previewContainer = document.getElementById('preview-container');
function generateImagePreview(file) {
const fileReader = new FileReader();
fileReader.addEventListener('load', event => {
// generate an image preview
let image = document.createElement('img');
image.classList.add('preview-image');
srcAttr = document.createAttribute('src');
srcAttr.value = fileReader.result;
image.setAttributeNode(srcAttr);
previewContainer.append(image);
}, false);
// open and read the file
fileReader.readAsDataURL(file);
}
function processFiles(files) {
previewContainer.innerHTML = "";
([...files]).forEach((file, index) => {
if (!file.type.match(imageTypeFilter)) {
console.error("Incorrect file type:");
console.log(file);
} else {
generateImagePreview(file);
}
});
}
dropZone.addEventListener('dragover', event => {
// required to fire the drop event
event.preventDefault();
});
dropZone.addEventListener('drop', event => {
event.preventDefault();
const files = event.dataTransfer.files;
fileInput.files = files;
processFiles(files);
});
fileInput.addEventListener('change', event => {
processFiles(event.target.files);
});
.upload {
border: 1px solid #eee;
border-radius: 10px;
padding: 20px
}
.preview-image {
max-width: 100px;
max-height: 100px;
}
.hidden {
opacity: 0.5;
}
<div id="dropzone" class="upload">
Drag images here
</div>
<input id="file-input" type="file" multiple accept="image/jpeg,image/png,image/gif" class="hidden" />
<div id="preview-container"></div>
2 Perform an AJAX upload when the user clicks the submit button.
In this case, you want to override the default the form submit event which I believe would look something like this:
const submitUrl = 'https://httpbin.org/post';
const form = document.getElementById('ajax-form');
form.addEventListener('submit', event => {
// this line prevents the default submit
event.preventDefault();
// convert the form into POST data
const serializedFormData = new FormData(event.target);
// use your favorite AJAX library
axios.post(
submitUrl,
serializedFormData
).then(response => {
console.log("success!");
}).catch(error => {
console.log("falied");
console.log(error.response);
});
});
<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
<form id="ajax-form" method="post" enctype="multipart/form-data">
<input type="text" name="name"/>
<input name="file" type="file" />

Now, the trick is to get hands on the schema used for generating this, which is perhaps proprietary for microsoft and may not be given out. So, the workaround is, if your excel file is failrly simple, you can save it as the Workbook and see the XML and generate an XSD based on it.
Now, map your incoming XML to this Workbook XSD and the resultant XML will open directly in Excel, when you double-click on it.

d7850 | train | You should return false from your .click() handler. But looking at your code there is something conceptually wrong with it. You call the .load method immediately after firing off your AJAX request without even waiting for this AJAX request to finish.

Write it down, break it down into steps, look at what you've done, roll up the loops. Then write the code.

d7867 | train | As per your query filter and columns needed, please make index on respected columns.
By default SQL will create clustered index on your primary key, but you may create some other unclustered index on your table to make your execution faster.
You may find this link for your reference or Google it there are hundreds of article available on Internet for same.

Just adding the connection properties and pool properties in yaml file or properties file under src/main/resources. It will inject the data source for you. | unknown | |

d7872 | train | If you have associated your application with a particular file extension, it will be launched automatically when you double-click such a file (as you have said).
When this happens, your application is launched with the file name (actually the full path) supplied as a command line argument to your application.
In SDI MFC applications, this is handled automatically by the framework as long as you haven't overridden the default File/Open handling mechanism, but if you have a dialog-based application you will need to add code for this yourself.
A: Your dialog COpenImageDlg is created and displayed inside the call to DoModal before the command line has a chance to be processed. When the DoModal returns, the dialog is already destroyed, so there is no dialog for the code to draw upon.
A: I understand that when you double click the file to choose a image on file dialog, the image doesn't show. I just tried your code of function OnBnClickedButton1 and OpenImage1. And it turns out that the image is displayed when double click to choose a image. I use VS2010 on win7. I hope this will help you though i donot find the error of your code.
A: I found the answer to my question.
It was actually a very stupid mistake.
When I read the file address using Commandline, the address has single slash, whereas I need to pass the address using double slash.
Such a silly bug. Sorry to waste your time. | unknown | |
d7873 | train | Use caution, as you may need to further qualify the WHEN NOT MATCHED BY SOURCE.
For example, if the TARGET table has a column that the SOURCE does not .. and you are setting that target column during the aforementioned insert .. then you'll likely want to define that constraint:
WHEN NOT MATCHED BY SOURCE AND (TARGET.SomeColumn = yada)
A: WHEN NOT MATCHED BY TARGET - You should use this clause to insert new rows into the target table. The rows you insert into the table are those rows in the source table for which there are no matching rows in the target.
WHEN NOT MATCHED BY SOURCE - If you want to delete a row from the target table that does not match a row in the source table
A: Yow want to match target table with source table.at end your target table should be similar to source table
WHEN NOT MATCHED BY SOURCE : focus on SOURCE : there is some rows in target that you don't have any equivalent for it in source table. so you should delete it.
WHEN NOT MATCHED BY Target: focus on Target : there is some rows in Source that you don't have any equivalent for it in Target table. so you can insert them | unknown | |
d7874 | train | Yes, you need a different way, because of event-driven nature of Tkinter GUI programming. When some event lead you to your wait() function there it is: you're stuck in infinite loop, and you can't get outside with events anymore!
As @Bryan Oakley pointed - GUI is constantly in a waiting state by default, since you reached a mainloop(). And I think, that you trying just suppress all other events (or just navigate keys) when user navigating through a tree , except this two (Left and Right clicks).
So here is a small example:
import tkinter as tk
# Main - application
class App(tk.Tk):
# init of our application
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.minsize(width=450, height=100)
self.wm_title('Just another example from SO')
self.wait_state = False
self.init_events()
# switch state
def switch_wait_state(self, event):
self.wait_state = not self.wait_state
print('Wait state switched to: %s ' % self.wait_state)
# init events
def init_events(self):
self.bind('<Key>', self.wait)
self.bind('<Control-s>', self.switch_wait_state)
# waiter(listener) for keypress
def wait(self, event):
if self.wait_state and any(key == event.keysym for key in ['Left', 'Right']):
print('I have successfully waited until %s keypress!' % event.keysym)
self.do_smth(event.keysym)
else:
print('Wait state: %s , KeyPress: %s' % (self.wait_state, event.keysym))
self.do_nhth()

d7875 | train | For anyone who might find this question later on: the problem was about having the right absolute path to your DB in your SQLALCHEMY_DATABASE_URI config value.
Also (this wasnt the case here, but it might possibly gotcha with the same symptoms) - if you omit __tablename__ on Model declaration, SQLAlchemy might autogenerate something you wont expect. Just a thing to keep in mind, if you're working with an existing DB with some schema already in place. | unknown | |

The Stored proc begin called 5 times makes for less code and may be less error prone, the cursor only iterates through your people once, but does not filter. I suspect the stored proc solution below will be faster but it will depend on your data.

A: Tried using ABAddressBookCopyLocalizedLabel?
Something like:
ABAddressBookRef ab = ABAddressBookCreate();
ABRecordID personID = <someid>;
CFIndex phoneNumberIndex = <anIndexFromSomewhere>;
ABRecordRef person = ABAddressBookGetPersonWithRecordID(ab, personID);
CFStringRef name = ABRecordCopyCompositeName(person);
ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
CFStringRef number = ABMultiValueCopyValueAtIndex(phoneNumbers, phoneNumberIndex);
CFStringRef label = ABMultiValueCopyLabelAtIndex(phoneNumbers, phoneNumberIndex);
CFStringRef localizedLabel = ABAddressBookCopyLocalizedLabel(label);
NSLog(@"Person: %@", name);
NSLog(@"%@ : %@", localizedLabel, number);
CFRelease(label);
CFRelease(localizedLabel);
CFRelease(number);
CFRelease(phoneNumbers);
CFRelease(name);
CFRelease(ab);
A: You'll have to detect labels with the suffix and prefix. Then do a substring to get the label.
The values you're getting are the correct label of the strings in the address book database. They're just polished up a bit before presentation to the user. That's all.
A: In the newer Contacts framework, you have a class function
Here is the example in swift 4
let emailValue: CNLabeledValue<NSString> = ...
let label = emailValue.label ?? ""
let prettyLabel = type(of: emailValue).localizedString(forLabel: label)
This changes "_$!<Work>!$_" to "work"
Even better you can make an extension
extension CNLabeledValue {
@objc func prettyLabel() -> String? {
if let label = label {
return type(of: self).localizedString(forLabel: label)
}
return nil
}
}
And now you have even more simple call
let emailValue: CNLabeledValue<NSString> = ...
let prettyLabel = emailValue.prettyLabel() | unknown | |
d7885 | train | The problem is the flexbox, it breaks because your div doesnt have the properties it needs.
.MuiGrid-grid-xs-12 {
flex-grow: 0;
max-width: 100%;
flex-basis: 100%;
}
Adding this to the div will have the same result like giving the Grid the style property directly.
But the left,right and top border will be outside of the view, because of the .MuiGrid-spacing-xs-3 class.
.MuiGrid-spacing-xs-3 {
width: calc(100% + 24px);
margin: -12px;
}
Depending on your needs use a different spacing like 0 for normal 100% width without margin and at it yourself.
A: I don't know what you expect as result, but you can do is add width:100% to your div.
Another option would be to add the same classes a Grid has, that would be MuiGrid-root MuiGrid-item MuiGrid-grid-xs-12
Result:
option 1 <div style={{ border: "4px double black", width: '100%' }}>
options 2 <div className="MuiGrid-root MuiGrid-item MuiGrid-grid-xs-12" style={{ border: "4px double black" }}>
A: Just add your border styles to classes.paper
It seems from your example that you can just add the border to the paper inside the grid element to get the desired style.
paper: {
padding: theme.spacing(2),
textAlign: "center",
color: theme.palette.text.secondary,
border: "4px double black"
}
If you want multiple classes on an element, use string interpolation:
<Paper className={`${classes.paper1} ${classes.paper2}`}> | unknown | |

d7887 | train | getItems is a redux action, you need to call it in dispatch
dispatch(getItems()) | unknown | |
d7888 | train | I guess your start_date column has the DATETIME or the TIMESTAMP data type. If that isn't true, please update your question.
There's a common trap in date-range processing in all kinds of SQL, due to the fact that when you compare a pure DATE with a DATETIME, they hardly ever come out equal. That's because, for example, DATE('2011-07-1') means the same thing as 2011-07-01 00:00:00.
So you need
start_date >= '$start_date_start'
AND start_date < '$start_date_end' + INTERVAL 1 DAY
instead of what you have, which is
start_date BETWEEN '$start_date_start%' AND '$start_date_end%' /*wrong!*/
The second clause with the < ... + INTERVAL 1 DAY picks up all possible times on the last day of your interval.
Edit Now that you've disclosed that you have two DATETIME columns, called start_date and end_date, it sounds like you're looking for items which start on or before a specific date, and end on or after that same date. Try something like this:
WHERE DATE(start_date) <= DATE('$specific_date')
AND DATE(end_date) >= DATE('$specific_date')
The trick on queries like this is to spend the majority of your time thinking through and specifying the results you want. If you do this, the SQL is often perfectly obvious. | unknown | |
d7889 | train | You can use splice and join like:
function customSplit(str, splitter, max) {
let res = str.split(splitter);
if(max < res.length)
res.push(res.splice(max - 1).join(splitter));
return res;
}
console.log(customSplit('Billy Bob Joe', ' ', 2));
console.log(customSplit('a b c d e f g h', ' ', 4));
A: Try something like this (run code snippet to see result):
var base_str = 'Billy Bob Joe whatever';
//try here limit 1 , 2, 3 and see console.log result
var base_split = base_str.split(' ',2);
var second_str = base_split.join(' ');
var second_split = base_str.split(second_str);
base_split.push(second_split[1].trim());
console.log(base_split);
A: Here is what I came up with, but it's not super optimized
function explode(del, str, limit) {
let items = str.split(del), r = []
for(let i = 0; i < limit - 1; i++){ r.push(items.shift()) }
r.push(items.join(' '))
return r
}
console.log(explode(' ', 'Billy Bob Joe', 2));
console.log(explode(' ', 'a b c d e f g h', 4));
A: You can create a function that will create a regex string matching the number of words passed as an argument.
const buildRegexString = function(numWords) {
let regexStr = '^'
for (let i = 1; i < numWords; i++) {
regexStr += '(\\S+)\\s';
}
regexStr += '(.*)';
return regexStr;
}
const input = 'Billy Bob Joe Ringo George';
const regex = new RegExp(buildRegexString(3));
const match = input.match(regex);
const result = match.slice(1);
console.log(result);
A: I think you can't do that using split function
you can use
var str = "Billy Bob Joe";
var res = str.split(" ",1);
str=str.replace(res,'');
Now str have Bob Joe | unknown | |
d7890 | train | When you get an exception and you don't understand what's causing it, a good first step is to isolate exactly where it is happening. There are a lot of things happening in that one line of code, so it's difficult to know exactly what operation is causing the error.
Seeing the full stack trace of the exception might help, since it would give an idea of where you are in the execution path when the exception occurs.
However, a simple debugging technique is to break that one line with many operations into many lines with fewer operations, and see which line actually generates the exception. In your case this might be something like:
Object o = request.getAttribute("testVal");
String s = (String) o;
boolean b = Util.parseBoolean( s, false )
If the cause suggested by Shivan Dragon is correct, then the exception would occur on the second of these three lines.
A: Most likely this code: request.getAttribute("testVal") returns a Boolean, which cannot be cast to String, hence the (runtime) exception.
Either:
*
*check for code that populates the request attribute "testVal" with the boolean value (something like request.setAttribute("testVal", Boolean.FALSE)) and replace the value with a String
or
*
*Don't cast the value to String in your code, and don't use what seems to be a utility class for building a boolean value out of a String (*)
(*) which, btw, the Boolean class can do all by its lonesome self, no need to make your own library for that:

d7891 | train | Why not just write the code for it?
var listOfA = new List<A>();
var listOfB = new List<A>();
... // Code for adding values
listOfA.ToC(listOfB);
public static class OuterJoinExtension

public static List<C> ToC(this List<A> listOfA, List<B> listOfB)
{
var listOfC = new List<C>();
listOfA.ForEach(a => listOfB.ForEach(b =>
{
if (b.JoinId == a.JoinId)
{
listOfC.Add(new C { Id = a.Id, JoinId = b.JoinId, Name = b.Name });
}
}));
return listOfC;
}
}
A: For simplicity I'll assume these are contained within another class:
class Original
{
List<ClassA> ClassAs { get; set; }
List<ClassB> ClassBs { get; set; }
}
class Result
{
List<ClassC> ClassCs { get; set; }
}
You can map the former to the latter using
Mapper.CreateMap<Original, Result>().ForMember(x => x.ClassCs,
x => x.MapFrom(x.ClassAs.Join(
y.ClassBs,
xEntry => xEntry.JoinId,
yEntry => yEntry.JoinId,
(xEntry, yEntry) => new ClassC {
Id = xEntry.Id,
Name = yEntry.Name,
JoinId = xEntry.JoinId}); | unknown | |
d7892 | train | If you have some patience (about 50s worth), you'll see that you do get one line of output and that line will be "1\n". You have two problems:
*
*count is using buffered output. This means that nothing will show up in your stdin until count's output buffer is full; given the small number of bytes that you're printing, the buffer won't be flushed until count finishes.
*Your popen block is only looking for one line.
You can solve the first one by using STDOUT.sync = true to turn off the output buffering in count:
STDOUT.sync = true
for i in 1..50 do
STDOUT.puts i
sleep 1
end
Then in your popen, you can iterate over the lines using each:
IO.popen("count","r+") { |fp| fp.each { |line| puts line } }
Then you should one line of output showing up each second. | unknown | |
d7893 | train | I'm happy to say that I've forgotten how SourceSafe works, but Subversion has an export feature that will copy the current version of all files. You can also set up commit hooks that will perform tasks whenever someone commits changes. | unknown | |
d7894 | train | You could use @keyframes animation and nested styles in SCSS to achieve something like this without javascript. Not sure if you're wanting to go this route, but it seems the most straightforward to me.
Particularly you're looking to set the animation-iteration-count to infinite on the elements that you want to rotate.
The below code is just some rough concept stuff, not sure the animation you're looking to set, or the full context of your elements, etc.
.logoSvg {
&:hover {
&:first-child {
animation-name: someAnimation;
animation-iteration-count: infinite;
}
&:last-child {
animation-name: someAnimation;
animation-iteration-count: infinite;
}
}
}
@keyframes someAnimation {
0%: {transform: some transformation};
100%: {transform: some transformation};
}
I hope this is helpful Chris, or at least gets you going in the right direction.
A: The rollover code itself looks ok (assuming missing code is, if you still get stuck I would put up a jsfiddle or jsbin), it's just applying to the wrong type of elements.
I'm guessing you are using jquery for the selections? If so, I'm not sure that will work..rather than doing..
var logo = $("#logoSvg");
try
var logo = Snap("#logoSvg");
That way you will get the Snap element (which links to the DOM element) to operate on, not a DOM or jquery object.
You can't transform the 'svg' element itself typically (as it doesn't technically support the transform attribute as far as I'm aware).
So, I would put the two svgs you want to transform inside a g/group element and transform that g element. You could look into css, but css transforms on svg don't always play nice regarding browser support, so whilst Davids answer may be good for normal elements, I'm not sure it would play nice for svg elements (especially rotations), do test different browsers very early if you do try that method. | unknown | |
d7895 | train | (Gathered from the now removed comments)
I have tried myself to build myself v4.14.78 followed by the latest available v4.14.214. I have found that former fails while the latter builds. So, I have bisected down to v4.14.116 that first builds correctly. Then I simple looked into the changes and found commit 760f8522ce08 ("selinux: use kernel linux/socket.h for genheaders and mdp") in the Linux stable tree which fixes the issue.
You may try to cherry-pick it to your branch and compile again. | unknown | |

foreach($cat_items AS $item)

d7898 | train | You should definitely not use single variables for each country. Instead use an array.
This can be done in multiple flavors:
*
*Use a VLA matching your list of names:
...
int lencountry = sizeof(countrylist)/sizeof(countrylist[0]);
int countrycounts[lencountry]; // VLA cannot be initialized
for (int i = 0; i<lencountry; i++)
{
countrycounts[i] = 0;
}
Then you can simply increment the corresponding index in that array:
if(!strcmp(countrylist[i], s[j]))
{
countrycounts[i]++;
}
*Use a struct and store counter together with names.
typedef struct {
const char *name;
int count;
} country_t;
country_t countrylist[] = {
{ .name = "Laotian / Lao"},
{ .name = "Afghanistan"},
{ .name = "Albania"},
...
{ .name = "Zambia"},
{ .name = "Zimbabwe"}
};
The remaining fields (here: count) in the struct are automatically initialized to 0 if not all fields are specified.
Then you can compare like this:
if(!strcmp(countrylist[i].name, s[j]))
{
countrylist[i].count++;
} | unknown | |
