d9902 | train | You can use NSStrings size for string in the heightForRow: delegate method e.g.
CGSize maxSize = CGSizeMake(300, 800); //max x width and y height
NSString *cellTitle = @"Lorem ipsum";
UIFont *stringFont = [UIFont systemFontOfSize:14]; // use the same font your using on the cell
CGSize cellStringSize = [myString sizeWithFont:stringFont constrainedToSize:maximumSize lineBreakMode: UILineBreakModeWordWrap];
This will give you a CGSize you can then use the height from here and add a little padding. You can find more information here: http://developer.apple.com/library/ios/#documentation/UIKit/Reference/NSString_UIKit_Additions/Reference/Reference.html

A: Use – sizeWithFont:constrainedToSize:lineBreakMode: of NSString (you can find more on this on this portal) or use an array containing height for every indexPath as shown in this example (SectionInfo class) http://developer.apple.com/library/ios/#samplecode/TableViewUpdates/Introduction/Intro.html. | unknown | |
d9903 | train | The smoothing attribute only affects how the video is scaled - that is, whether or not the video is smoothed if you play it at double size or the like. If your Video component is scaled the same size as the source video, this attribute won't do anything.
With that said, please understand that there's no such thing as anti-aliasing going on at the player end of things. Assuming that everything is the right size (so your video isn't being scaled up to 103% or anything), what you see in the Flash player is exactly the data in the source FLV. So any aliasing you see happened when the video was encoded, not at runtime.
So assuming your sizes are right, my guess would be that you should look at the encoding end of things to solve the problem. Is your FLV of a comparable size as the lossless quicktime? If it's a lot smaller, then you're probably compressing it a lot, and increasing the quality settings might help. Likewise, what codec did you use? If you're using the newest codec (H264), the quality ought to be very similar to a quicktime movie of similar size. But the older codecs can have significantly less quality. Especially the old Sorenson Sparc codecs (the ones that require player 6/7 or better to view) are pretty sad by today's standards. And especially the Sorenson codec was heavily customized for low-bandwidths, so even if you encode with very high quality settings you tend to get big increases in file size but very little increase in quality. For these reasons it's highly recommended to make sure you're using the newest codec available for the player version you're targeting.
If none of that helps, please update with some details about what codecs and encode settings you're using. | unknown | |
d9904 | train | Check your IPN history in PayPal. If it shows anything other than 200 response code you know something is wrong with your IPN listener.
You can check your web server logs to see exactly what error is happening when the script is hit.
Alternatively, you could setup a simple HTML form with hidden fields that match what you'd expect to get from PayPal. Then you can submit this in a browser so you can see the result on screen.
Keep in mind that testing this way will result in an INVALID response back from PayPal because the IPN data did not come from their server, but you can adjust for that accordingly for testing purposes, get your issues fixed, and then you'll be good to go.
A: Debugging tips: check your IPN configuration at the PayPal backend. Replace your script by a simple script that just shows you when it's called and with what input. | unknown | |

d9910 | train | One way would be to add a submit button to your form (it could be hidden) and invoke the click action so that it will trigger an asynchronous form postback:

<%=Html.Hidden("productid", shoppingCartItem.Product.ProductID.ToString())%>
<%=Html.TextBox("Quantity", shoppingCartItem.Quantity.ToString(), new { size = 2,
maxlength = 2, onchange = "document.getElementById('button').click();" })%>
<input type="submit" id="button" style="display: none" />

d9911 | train | You will want to create a server mapping of users to connection id's. See: SignalR 1.0 beta connection factory.
You will want to let your users persist past an OnDisconnected event and when they connect with a different connection Id you can continue pumping data down to them.
So the thought process could be as follows:
*
*Page loads, SignalR connection is instantiated
*Once connection is fully started call => TryCreateUser (returns a user, whether it existed or it was created).
*Long Running process Starts
*Client changes pages -> SignalR connection stops
*New Page loads, new SignalR connection is instantiated
*Once connection is fully started see if you have a cookie, session, or some type of data representing who you are => TryCreateUser(userData) (returns the user you created on the last page).
*Data continues pumping down to user.
Note: if you take an authentication approach you will have to be authenticated prior to starting a connection and that data cannot change during the lifetime of a SignalR connection, it can only be created/modified while the connection is in the disconnected state. | unknown | |

d9913 | train | You can with the help of the extension Command Variable it allows you to use the content of a file as a command in the terminal. The file can also contain Key-Value pairs or be a JSON file.
Say you store this userTask.txt or userTask.json file in the .vscode folder and add the file to the .gitignore file.
With the current version of the extension the file userTask.txt has to exist, I will add an option to supply alternative text in case the file does not exist. You can fill the file with a dummy command like echo No User Task

ActiveWorkbook.SaveAs filePath & counter & ".xlsx", FileFormat:=51
counter = counter + 1
Next ws

This is mostly taken from here.
The counter is a bit of a hack to make sure that the files aren't all being saved as the same name and overwriting each other. Maybe there's a more appropriate way that you can get around this. | unknown | |
d9915 | train | Check the account / IIS -> Application Pool -> Advanced Settings -> Process Model -> Identity under which your pool is running. I had my password changed, and didn't get a log on invalid password, but rather assemlby load failure, which in turn caused the app pool to be shut off, and the "503 Service Unavailable" was given to the user.
A: I figured it out. It was due to SQL Reporting services having reserved the http://+:80/Reports url in http.sys.
I didn't actually have reporting services installed, but it apparently still reserved the url.
I fixed it with the following command:
netsh http delete urlacl url=http://+:80/Reports
A: Another solution is, I had the same problem with my http://ApplicationURL/Reports
And yes the SSRS was the issue.
A better solution for this one is
*
*OpenReporting Services Configuration Manager.
*Connect to your local service usually COMPUTERNAME\MSSQLSERVER
*Go to "Report Manager URL" Option
*Modify your virtual directory with another name instead of Reports.
Just remember with this change you reports for SSRS will be in the name that you defined.

A: Are you using any ODBC or other components in this area that you are not anywhere else? I have experienced this error (or one similar, can't remember off the top of my head) when running the app pool in 64bit mode and the underlying calls are referencing at 32bit 'something'. You could try enabling 32bit applications in the application pool settings to see if it affects the outcome.
A: As mentioned before it is related to SQL Reporting services
You can follow this approach to fix this problem:
Log on to the server that hosts SSRS.
Go to Start > Programs > SQL Server 2008 R2 > Configuration Tools > Reporting Services Configuration Manager
Connect to the server in question (usually your local server)
Go to the Web Service URL section
Change the TCP port to an open port other than port 80 (81 happened to work on my server) and hit Apply
Go to the Report Manager URL section
Click Advanced
Click the entry with a TCP port of 80 and then click the Edit button.
Change the TCP Port entry to the same thing you changed it to in the Web Service URL section previously and Click OK.
Click OK again. | unknown | |
d9916 | train | You have already set functionAppScaleLimit to 1, another thing you should do is setting the batch size to 1 in host.json file according to this document :
If you want to minimize parallel execution for queue-triggered
functions in a function app, you can set the batch size to 1. This
setting eliminates concurrency only so long as your function app runs
on a single virtual machine (VM). | unknown | |
d9917 | train | You need to skip the first few lines, which you don't need.
Then split the lines to get the various numbers. Index 0 contains the serial no., 1 and 2 contain the coordinates. Then parse them to int. eg:
in.nextLine();// multiple times.
//...
String cs = in.nextLine(); // get the line
City city = new City(Integer.parseInt(cs.split(" ")[1]), Integer.parseInt(cs.split(" ")[2]));
TourManager.addCity(city);
String cs2 = in.nextLine();
City city2 = new City(Integer.parseInt(cs2.split(" ")[1]), Integer.parseInt(cs2.split(" ")[2]));
TourManager.addCity(city2);
String cs3 = in.nextLine();
City city3 = new City(Integer.parseInt(cs3.split(" ")[1]), Integer.parseInt(cs3.split(" ")[2]));
TourManager.addCity(city3);
A: Whenever you use in.nextLine(), actually it takes the string that you entered. So try to assign it to some string variable. For example:
String s =in.nextLine();
Also, just using in.nextLine(); which you did in 2nd,3rd 4th,8th and 9th line is not needed. | unknown | |
d9918 | train | Hi Finally i got the solution.
Here i am using getResponse = (HttpWebResponse)getRequest.GetResponse();
The problem is we can use only one HttpWebResponse at a time. In my case i am using the same object in two times without any disposing and closing. That's make me the error.
So I updated my code like this.
byteArray = Encoding.ASCII.GetBytes(postData);
getRequest.ContentLength = byteArray.Length;
newStream = getRequest.GetRequestStream(); //open connection
newStream.Write(byteArray, 0, byteArray.Length); // Send the data.
getResponse = (HttpWebResponse)getRequest.GetResponse();
getresponse.Close();
This solved my error. Thanks | unknown | |
d9919 | train | I'm getting a SOAP request as string, from which I want to extract a
Java object. Is it possible?
Yes.
If yes, then how?
You need to convert the String into something that JAXB can unmarshal. Examples include a StringReader or XMLStreamReader.
What API can be used for this?
Since a SOAP message contains more information than what corresponds to the domain model I would recommend using JAXB with a StAX XMLStreamReader. You use StAX to parser the String. Then you advance the XMLStreamReader to the element that contains the content you wish to unmarshal. Then you unmarshal the XMLStreamReader at that point.

d9920 | train | You could try something like:
Cells(i, 2).Value = IE.document.getelementbyid("dtgGeneral_ctl02_lblLeftColumnEntName").getelementsbytagname("b").innerText
Cells(i, 3).Value = IE.document.getelementbyid("dtgGeneral_ctl02_lblLeftColumnPracAddr").innerText
Since address1, address2 and phone would all be in Cells(i, 3) you might want to use to use text to column to split them into their appropriate columns.
Additionally you could create an array to store these data in if you're doing a bigger search. Then you could paste the array values into their cells after you've finished scraping, like:
searchInfo(i, 1) = IE.document.getelementbyid("dtgGeneral_ctl02_lblLeftColumnEntName").getelementsbytagname("b").innerText
searchInfo(i, 2) = IE.document.getelementbyid("dtgGeneral_ctl02_lblLeftColumnPracAddr").innerText
Then after looping:
For i = 1 to last row
Cells(i,2).Value = searchInfo(i, 1)
Cells(i,3).Value = searchInfo(i, 2)
Next i
You'd still have the text to column issue but that can be solved pretty easily with some code in the loop. Specifics just depend on how the third column's values come out.
EDIT: Based on your comments below, this worked for me. It might take a little customizing, but this is the idea.

MyDataGrid.IsKeyboardFocusWithinChanged += (sender, e) => {

I thought the only difference between Invoke and BeginInvoke is that the first one waits for the task to be finished while the latter retuns instantly. Since the Dispatcher call is the only thing that happens in the EventHandler, I assumed that using Invoke would have the exact same effect as using BeginInvoke in this case. However I have a working example where this is clearly not the case. Take a look for yourself:

What we have here is a DataGrid which rows include a CheckBox. It implements two specific behaviors:
*
*When the DataGrid gets keyboard focus it will focus it's selected row (which for some reason is not the default behavior).
*You can change the state of a CheckBox with a single click even when the DataGrid is not focused.
This works already. With the assumption at the top of the post, I thought that it would not matter whether I use Invoke or BeginInvoke. If you change the code to BeginInvoke however, for some reason the 2cnd behavior (one-click-checkbox-selection) does not work anymore.
I don't look for a solution (the solution is just using Invoke) but rather want to know why Invoke and BeginInvoke behave so differently in this case. | unknown | |
d9923 | train | Since you're using componentWillReceiveProps to keep a local state in sync with props you have two alternatives:
Declare your initial state based on props and use componentDidUpdate to ensure props synchronicity
class Component extends React.Component{
state = { foo : this.props.foo }
componentDidUpdate(prevProps){
if(this.props.foo !== prevProps.foo)
this.setState({ foo : prevProps.foo })
}
}
This is actually triggering an extra render everytime, if you have some local state that is always equal to some prop you can use the prop directly instead.
Use getDerivedStateFromProps to update the state based on a prop change, but keep in mind that you probably don't need to use it
class Component extends React.Component{
static getDerivedStateFromProps(props){
return { foo : props.foo }
}
}
A: The answer to the question you asked is probably not going to be satisfactory. :-) The answer is that if you really need to derive state from props (you probably don't, just use props.errors directly in render), you do it with the newer getDerivedStateFromProps static method that accepts props and state and (potentially) returns a state update to apply:
static getDerivedStateFromProps(props, state) {
return props.errors ? {errors: props.errors} : null;
}
or with destructuring and without the unused state parameter:
static getDerivedStateFromProps(({errors})) {
return errors ? {errors} : null;
}
But, you're saying "But that doesn't do the authentication thing...?" That's right, it doesn't, because that componentWillReceiveProps shouldn't have, either, it violates the rule props are read-only. So that part shouldn't be there. Instead, if that entry in props.history is supposed to be there, it should be put there by the parent component. | unknown | |
d9924 | train | At the end of the day it's the docker container running on a machine and in docker container you can run services that listen to the data that is posted on those services. Some solutions can be:-
*
*A http server running on your edge module container and producers posting data to the RESTful api exposed by the container. Once data received, push it to IoT Hub using routes in edgeHub.
*You can also run a consumer on docker container that listens to a message broker and passes that data to IoT hub using edgeHub routes. | unknown | |
d9925 | train | If you look at the help for strings:
Usage: strings [option(s)] [file(s)]
Display printable strings in [file(s)] (stdin by default)
You see that stdin is the default behavior if there are no arguments. By adding - the behavior seems to change, which is strange, but I was able to reproduce that result too.
So it seems the correct way to do what you want is:
data-source | strings | grep needle
In a comment, you asked why not strings datasource |grep -o needle ?
If you could arrange that command so datasource is a stream, it might work, but it's usually easier to arrange that using |.
For example, the below are roughly equivalent in zsh. You'd have to figure out a way to do it in your shell of choice if that's not zsh.

d9927 | train | There is no "best" - everything is contextual, and only you have most of the context.
However! Some minor thoughts on performance:
*
*a nested approach requires more objects; usually this is fine, unless your volumes are huge
*a nested approach may make it easier to understand the object model and the relationships between certain parts of the data
*a flat approach requires larger field numbers; field numbers 1-15 take a single byte header; field numbers 16-2047 require 2 bytes header (and so on); in reality this extra byte for a few fields is unlikely to hurt you much, and is offset by the overhead of the alternative (nested) approach:
*a nested approach requires a length-prefix per sub-object, or a start/end token ("group" in the protocol); this isn't much in terms of extra size, but:
*
*length-prefixe requires the serializer to know the length in advance, which means either double-processing (a "compute length" sweep), or buffering; in most cases this isn't a big issue, but it may be problematic for very large sub-graphs
*start/end tokens are something that google has been trying to kill, and is not well supported in all libraries (and IIRC it doesn't exist in "proto3" schemas); I still really like it though, in some cases :) protobuf-net (from the tags) supports the ability to encode arbitrary sub-data as groups, but it might be awkward if you need to x-plat later
Out of all of these things, the one that I would focus on if it was me is the second one.
Perhaps start with something that looks usable, and measure it for realistic data volumes; does it perform acceptably? | unknown | |
d9928 | train | I added some code to your Directory class. If you run it(I also added a Main method for testing purposes), you see it creates a list of directories and serializes this list as JSON.

markup += dirList[i].folderName + "<br />";

d9929 | train | //first, check number through GET

$text = $_GET['number'];
}else{
//second, check REQUEST_URI
$urlparts = parse_url( $_SERVER['REQUEST_URI']);
$text = $urlparts['query'];
}
echo $text;
A: Take a look at the parse_url() function. It takes a URL as the input and returns an array containing all of the separate parts.
A slightly altered example from the documentation:
$url = 'http://username:[email protected]/path?arg=value#anchor';
print_r( parse_url( $url ) );
Outputs:
Array
(
[scheme] => http
[host] => example.com
[user] => username
[pass] => password
[path] => /path
[query] => arg=value
[fragment] => anchor
)
I believe you are looking for the query part of the URL. From there you could possibly use the parse_str() function to split that string into variables. | unknown | |
d9930 | train | What helped me was checking every few seconds if my transactiopn finished, and if yes hiding the loader.
if (latestTx != null) {
window.web3.eth.getTransactionReceipt(latestTx, function (error, result) {

$(".Loading").hide();
console.error ('Error1::::', error);
}
console.log(result);
if(result != null){
latestTx = null;
$(".Loading").hide();
}
});

A: You don't need jquery to do this. React state can manage the status of the progress automatically. All you have to do is to call setState function.
class EthereumFrom1 extends React.Component {
state = {
loading: false
};
constructor(props) {
super(props);
this.doPause = this.doPause.bind(this);
}
doPause() {
const {pause} = this.state.ContractInstance;
pause(

gas: 30000,
gasPrice: 32000000000,
value: window.web3.toWei(0, 'ether')

(err) => {
if (err) console.error('Error1::::', err);
this.setState({loading: true});

d9932 | train | Insight can be gained by looking at how Microsoft does this for the SQL Server service. In the Services control panel, we see:
Service name: MSSQLServer
Path to executable: "C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn\sqlservr.exe" -sMSSQLSERVER
Notice that the name of the service is included as a command line argument. This is how it is made available to the service at run time. With some work, we can accomplish the same thing in .NET.
Basic steps:
*
*Have the installer take the service name as an installer parameter.
*Make API calls to set the command line for the service to include the service name.
*Modify the Main method to examine the command line and set the ServiceBase.ServiceName property. The Main method is typically in a file called Program.cs.
Install/uninstall commands
To install the service (can omit /Name to use DEFAULT_SERVICE_NAME):
installutil.exe /Name=YourServiceName YourService.exe
To uninstall the service (/Name is never required since it is stored in the stateSaver):
installutil.exe /u YourService.exe

<app-button (clickFunctionCalled)="callCustomClickFunction($event)"></app-button>
Add this in login.component.ts
callCustomClickFunction() {
console.log("custom click called in login");
this.login();
}
Basically, emit the click event from the child component. Catch the event in the parent component and call the desired function of the parent component.
You can also directly call the parent component's function like this
<app-button (clickFunctionCalled)="login($event)"></app-button>
As you are using dynamic component creator for creating the button component, you need to do something like this, for binding output event
loginButton.instance.clickFunctionCalled.subscribe(data => {
console.log(data);

String b = splits[1];
String c = splits[2];

a, b, c, d, e = name.split()
print(b)

A: str.replace(" ","");
or
String name = yourString.replace(" ","");

str.split();
A: For PHP/Java/JavaScript AND C# the explode() function may be what you're looking for.

$strings[] = explode(" ", $name);

You can add this functions to ReflectionOnClass:

this.number = num;
label.setText("X: " + this.number);

public int getNumber(){
return this.number;
}
and just call them from ExecReflection:

rF.setNumber(4);
System.out.println("Value number: " + rF.getNumber());
A: Nothing is changing because you are not actually changing value that is displayed
private int number = 2;
private JLabel jLabel = new JLabel("X: " + number);
You need to access jLabel field, as this is your displayed value, and change text to something else, if number is used in other places, then you probably need to change both of them, so number to this example 100 value, and jLabel text to X: 100 | unknown | |

d9954 | train | I seems that your object doesn't get transparent, but rather that it is being covered by the other object even though it should be in front of it.
Sorting is a common problem with objects that use some sort of blending:
In this case this is probably due to the other object being in a ui element. You could try to enforce the draw order by modifying the render queue in the material, or force it to use depth testing by using an alpha cutout shader instead (but its edges will not look as nicely anti-aliased without an extra MSAA or FXAA) | unknown | |
d9955 | train | I think you've got the solution space right: Either disambiguate the call by passing in only explicitly size_t-typed ns, or use SFINAE to only apply the range constructor to actual iterators. I'll note, however, that there's nothing "magic" (that is, nothing based on implementation-specific extensions) about MSVC's _Is_iterator. The source is available, and it's basically just a static test that the type isn't an integral type. There's a whole lot of boilerplate code backing it up, but it's all standard C++.
A third option, of course, would be to add another fill constructor overload which takes a signed size. | unknown | |

d9958 | train | Quick guess - Try (untested):
$write = '
<?php
include "/home/history/public_html/issue1.php";
echo \'<a class="prev" href="' . $data[16] . '">\';
?>
';
It's just a bit tricky with the multiple quotes... think you might have lost track of which ones need escaping...
Hmmmm... so that didn't work... the next thing I would try is to construct the $write variable over several lines (hopefully making the job a bit easier, so perhaps easier to avoid error) - note that I also threw in a repeating filewrite to see what the output is:
$hF = fopen('__debug.log', "a"); //outside your loop
//inside loop
$hrf = $data[16];
$write = '<?php' + "\n";
$write .= 'include "/home/history/public_html/issue1.php";' + "\n";
$write .= "echo '<a class=\"prev\" href=\"";
$write .= $hrf;
$write .= "\">';" + "\n";
$write .= '?>';
fwrite($hF, $write);
and make sure to close the file before your script ends:
//outside the loop
fclose($hF);
A: Using a variable inside a write statement didn't work while inside a fopen statement. I ended up having to use ob_start to get it to work. Hat tip to gibberish for getting me on the right path.
<?php
ob_start();
include 'issue1.php';
$issueone = ob_get_contents();
ob_end_clean();
$row = 1;
if (($handle = fopen("issue-heads-1.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle)) !== FALSE) {
$csv[] = $data;
}
fclose($handle);
}
$file = fopen($csv[$row][14], "w") or die("Unable to open file!");
fwrite($file, $issueone);
fwrite($file, "<a class=\"prev\" href=\"" . $csv[$row][16] . "\">");
fclose($file);
print "ok";
?>
A: If you have unique headers in your CSV
$headers = [];
while (false !== ($data = fgetcsv($handle))) {
if(empty($headers)){
$headers = $data; //["foo", "bar"] (for example)
continue; //skip to next iteration
}
//$data [1,2] (for example)
$row = array_combine($headers, $data);
//$row = ["foo"=>1,"bar"=>2] (for example)
}
Now you can use the text headers instead of 16 etc...
One thing to be careful of is array combine is very sensitive to the length of the arrays. That said if it errors you either have duplicate keys (array keys are unique) or you have either an extra , or a missing one for that line.
Array combine takes the first argument as the keys, and the second as the values and combines them into an associative array. This has the added benefit that the order of your CSV columns will not be important (which can be a big deal).
PS as I have no idea what your headers are, I will leave that part up to you. But lets say #16 is issues. Now you can simply do $row['issues'] just like a DB source etc...

d9962 | train | Late answer, but maybe it will help someone. For me the key to getting unique fb comments to render on a single page application was FB.XFBML.parse();
Each time I want to render unique comments:
*
*Change the url, each fb comments thread is assigned to the specific url
So I might have www.someurl.com/#123, www.someurl.com/#456, www.someurl.com/#789, each with its own fb comment thread. In AngularJs this can be done with $location.hash('123');
*Create a new fb-comments div, where 'number' equals '123', '456' or '789'
<div class="fb-comments" data-href="http://someurl.com/#{{number}}" data-numposts="5" data-width="100%" data-colorscheme="light">

d9966 | train | So, I think you have a few issues here.
1. QWidget
The big one is that QWidget (which QQUickWidget inherits from) does not have a signal called "clicked", so the message QObject::connect: No such signal QQuickWidget::clicked() is quite right ;)
What you need to do is create your own object that inherits from QQuickWidget and then re-implement/overload the function void QWidget::mousePressEvent(QMouseEvent * event) and/or void QWidget::mouseReleaseEvent(QMouseEvent * event)
These are the functions that are called in the widget that you can then emit your signal. Which means you also need to add a new signal into you your widget. So your new class header may look a bit like (just including the main elements):
class MyQQuickWidget: public QQuickWidget
{
Q_OBJECT
public:
MyQQuickWidget(QWidget *parent = 0);
signals:
void clicked();
protected:
void mousePressEvent(QMouseEvent *event) Q_DECL_OVERRIDE;
void mouseReleaseEvent(QMouseEvent *event) Q_DECL_OVERRIDE;
};
And then in your implementation:
void MyQQuickWidget::mouseReleaseEvent(QMouseEvent *event)
{
if (event->button() == Qt::LeftButton) {
emit clicked();
}
}
Then when you connect your MyQQuickWidget signal clicked() to MyClass slot slot() it will connect ok.
2. QTimer
It looks like your timer should fire... but there appears to be no debug in the slot slot() so how would you know if this is working or not? | unknown | |

d9968 | train | There is nothing like a Physical Class Diagram, just class diagrams (you may consult Superstructures if you like). What you probably mean is the difference between class model and physical model. The latter focuses on the concrete implementation of a class model. It shows libs, hardware and things you'd need to implement your more abstract class model on some real hardware. With the MDA this part is called PSM (platform specific model) in contrast to the PIM (platform independent model). | unknown | |
d9969 | train | Your example is pretty flawed for any use case in which alerting the developers would be needed. This would need to alert the user not to input a negative number.
def times_two(x):
if x < 0:
raise BrokenException("Attn user. Don't give me negitive numbers.")
return x * 2
Although, I think if your example more accurately described an actual error needing developer attention then you should just fix that and not put it into production knowing there is an error in it.
sentry.io on the other hand can help find errors and help developers fix errors while in production. You may want to look into that if warnings isn't for you. From their README.me:
Sentry fundamentally is a service that helps you monitor and fix
crashes in realtime. The server is in Python, but it contains a full
API for sending events from any language, in any application.
A: Builtin Exception 'ValueError' is the one that should be used.
def times_two(x):
if x < 0:
raise ValueError('{} is not a positive number.'.format(x))
return x * 2
A: This seems like an XY problem. The original problem is that you have some code which is incomplete or otherwise known to not work. If it is something you are currently working on, then the correct tool to use here is your version control. With Git, you would create a new branch which only be merged into master and prepared for release to production after you have completed the work. You shouldn't release a partial implementation.
A: Do you want to stop execution when the function is called? If so, then some sort of exception, like the BrokenException in your example is a good way of doing this.
But if you want to warn the caller, and then continue on anyway, then you want a Warning instead of an exception. You can still create your own:
class BrokenCodeWarning(Warning)
pass
When you raise BrokenCodeWarning, execution will not be halted by default, but a warning will be printed to stderr.
The warnings filter controls whether warnings are ignored, displayed, or turned into errors (raising an exception).

d9970 | train | I did a lot of digging and I was able to find something that worked.
There is a helper that comes with rails called options_for_select(). What this does is it will take something like this
<%= select_tag(:destination, '<option value="1">SLC</option>...') %>
And it will auto-generate the options using a multidimensional array
Since I already had a multidimensional array by using the select_options method, I was able to use them both in conjunction with each other like so:
<td><%= select_tag(:destination, options_for_select(Location.select_options)) %></td>
This pulls up exactly what I needed, and appends the correct value to the database when selected.
Another method is without the options_for_select helper, but it would need to have a parameter for which row is selected available.
@pallet = Pallet.find(2)
<td><%= select(:pallet, :destination, Location.select_options) %></td>
The advantage of this one is that it automatically defaults to what was already there. This makes it easier for when you update something that isn't the location. | unknown | |

val it : Series<System.Int64,float> =
2 -> 2
>
val it : Series<System.Int64,float> =
2 -> 2
3 -> 3
4 -> 4
5 -> 5
Depending on what you're trying to do Selecting Specific Rows in Deedle might also work.
Edit
From your comment you appear to be working with some large table. Depending on how much memory you have and how large the table you still might be able to load it. If not these are some of things you can do in increasing complexity:
*
*Use a query { } expression like above to narrow the dataset on the database server and convert just part of the result into a dataframe. You can do quite complex transformations so you might not even need the dataframe in the end. This is basically Linq2Sql.
*Use lazy loading in Deedle. This works with series so you can get a few series and reassemble a dataframe.
*Use Big Deedle which is designed for this sort of thing. | unknown | |
d9974 | train | Having this same issue, last time I resolved it by back-switching to Python 3.8.7 perhaps. But now I installed 3.11 and now again pysha3 is not installing. (Window 10) | unknown | |
d9975 | train | The solution:
You will need to browse to this installation path:
C:\SQLServer2017Media\<YOUR_SQL_ENU>\1033_ENU_LP\x64\Setup
Then while the setup is stuck at “Install_SQLSupport_CPU64_Action” run
SQLSUPPORT.msi
And follow the installation procedure.
Once installed, run the following command in cmd:
taskkill /F /FI "SERVICES eq msiserver"
The SQL Server setup will continue and succeed.
Edit:
according to @snomsnomsnom, it seems that SQL Server 2019 unpacks to C:\SQL2019...
if the error code is 0x851a001a, then you need to change the sector size of the hard drives. Here is the guideline for that.
https://learn.microsoft.com/en-us/troubleshoot/sql/admin/troubleshoot-os-4kb-disk-sector-size
A: I had this issue when installing sql server 2016, the taskkill solution not work for me. Therefore, I tried do uninstallation for SQL Server 2012 Native Client, and install the one in the setup\x64\sqlncli.msi and reinstall the sql server again, and no more issue anymore. | unknown | |
d9976 | train | Most of your ActionScript code must go inside a method; and you have code that must be put in a method. Variable definitions are okay. Import statements are okay. I think some directives, such as include are okay. But, other code must be in a method.
This is your annotated code:
<fx:Script>
<![CDATA[
// this is a variable definition so it is good
var xmlLoader:URLLoader = new URLLoader();
// these two lines are code that executes; so they must be put inside a method; something you did not do. Comment them out
//xmlLoader.addEventListener(Event.COMPLETE, loadXML); // 1st error here
//xmlLoader.load(new URLRequest("books.xml")); // 2nd error here
// this is a variable definition so it is okay
var xmlData:XML = new XML();
// this is a function definition so it is okay
function loadXML(e:Event):void{
xmlData = new XML (e.target.data);
}
// move your executing code into a method
public function load():void{
xmlLoader.addEventListener(Event.COMPLETE, loadXML);
xmlLoader.load(new URLRequest("books.xml"));
}
]]>
</fx:Script>
I bet that removes your errors. However, you'll also want to / need to do something to execute that load method. When you do this depends on how the data is used in your app and the current component. But, I'd probably add a preinitialize event listener:
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
preinitialize="load()">
If preinitialize doesn't work; I'd move the code to the initialize event. If that doesn't work; I'd go to the creationComplete event. | unknown | |

d9979 | train | Fortran allocatables may imply dynamic memory allocation (whether or not that is then actually done on the offloading device), and that is implemented via support routines in libgfortran. I suppose _gfortran_os_error would be called in case of a memory allocation error. Per https://gcc.gnu.org/PR90386 "Offloading: libgfortran, libm dependencies" you currently have to manually specify -foffload=-lgfortran to resolve such errors. | unknown | |
d9980 | train | The general mental model is that unstaged changes are left alone, and everything else in the working copy is updated when checking out a different commit. Or as the docs put it:
git checkout <branch>
To prepare for working on <branch>, switch to it by updating the index and the files in the working tree, and by pointing HEAD at the branch. Local modifications to the files in the working tree are kept, so that they can be committed to the <branch>.
This is consistent with both cases that you've observed. | unknown | |
d9981 | train | If your input in prompt( either cmd or powershell) is causing problems due to incompatibility of using differents encodings just try to encode it via methods in script.encode "UTF-8" #in case of Ruby language If you dont know what methods do that just google your_language_name encoding | unknown | |
d9982 | train | First of all, your loop should start at viewlist.Items.Count - 1 and end at 0. This is because the right side of To is only evaluated prior to the first iteration. Due to this the loop will go to whatever viewlist.Items.Count - 1 was before the loop was run, instead of what it actually is after removing items (hence why you got the ArgumentOutOfRangeException from my previous code).
By starting from the end and going towards 0 i will always represent a valid index as long as you remove at most one item per iteration. This can be illustrated by the following:
First iteration Second iteration Third iteration (and so on)
Item 0 Item 0 Item 0
Item 1 Item 1 (i) Item 1
Item 2 (i) Item 2 [Removed]
(i) Item 3 [Removed] [Removed]
Now, to get a sub-column of an item you can use the ListViewItem.SubItems property. Your Gender column is currently at index 1 - the first sub-item (index 0) is apparently the owner of all sub-items, that is, the original ListViewItem.
For i = viewlist.Items.Count - 1 To 0 Step -1
Dim CurrentSubItems As ListViewItem.ListViewSubItemCollection = viewlist.Items(i).SubItems
If CurrentSubItems.Count >= 2 AndAlso CurrentSubItems(1).Text = ComboBox4.Text Then
viewlist.Items.RemoveAt(i)
End If
Next
ComboBox4.Items.Remove(ComboBox4.Text)
If you want to use case-insensitive string comparison you can change the If-statement in the loop to:
If CurrentSubItems.Count >= 2 AndAlso String.Equals(CurrentSubItems(1).Text, ComboBox4.Text, StringComparison.OrdinalIgnoreCase) Then | unknown | |

d9984 | train | PDO solution
Assuming you're using PDO(not specified by you), if you want to save it as blob then following steps should be done
try
{
$fp = fopen($_FILES['fic']['tmp_name'], 'rb'); // read the file as binary
$stmt = $conn->prepare("INSERT INTO image (titre, selogon, description, img_blob) VALUES (?, ?, ?, ?)"); // prepare statement
// bind params
$stmt->bindParam(1, $img_titre);
$stmt->bindParam(2, $selogon);
$stmt->bindParam(3, $description);
// this is important I will explain it below after the code
$stmt->bindParam(4, $fp, PDO::PARAM_LOB);
$stmt->execute();
// if you want to check if it was inserted use affected rows from PDO
}
catch(PDOException $e)
{
'Error : ' .$e->getMessage();
}
The most important thing is bind the file pointer ($fp) to PDO param called LOB which stands for Large Object
PDO::PARAM_LOB tells PDO to map the data as a stream, so that you can manipulate it using the PHP Streams API.
http://php.net/manual/en/pdo.lobs.php
After that you can use power of PHP streams and save it as binary safe stream. Reading the from streams make more sense but if I were you I'd really think if you want to save pictures directly in db, this doesn't seem to be a good idea.
MYSQLI solution:
If you don't use PDO but for example mysqli then streams are good idea as well but the solution is different.
The best option is to check SHOW VARIABLES LIKE 'max_allowed_packet'; this will print what is max allowed package size, if your image is bigger the blob will be corrupted.
To make it work you'll need to send data in smaller chunks using fread() + loop + feof() and mysqli function send_long_data
Example from php.net site: you can adjust it to your needs quite similar as I did above, the difference is that params are bound in different way.
$stmt = $mysqli->prepare("INSERT INTO messages (message) VALUES (?)");
$null = NULL;
$stmt->bind_param("b", $null);
$fp = fopen($_FILES['fic']['tmp_name'], "r");
while (!feof($fp)) {
$stmt->send_long_data(0, fread($fp, 8192));
}
fclose($fp);
$stmt->execute();

d9989 | train | Short answer you can't. Why?
Simply because 500 - Internal Server Error is exactly what it says Internal Server Error, it has nothing to do with Laravel. Server software (Apache in your case) causes error 500. Most likely permissions problem. (server software can not read / write to certain files etc.)
From Laravel documentation:
After installing Laravel, you may need to configure some permissions. Directories within the storage and the bootstrap/cache directories should be writable by your web server or Laravel will not run.
You have to check Apache logs
Default on OSX machine /private/var/log/apache2
You want to see more errors? Follow up this SO thread.

d9991 | train | You didn't post your entire grammar, so I cannot tell you what exactly is wrong with your grammar. You can however do something like this to parse your input:
file

translation : '<' ( text | var_def )* '>' ;
text
: TEXT+
;
var_def
: VAR_DEF_START text VAR_DEF_END

d9992 | train | If proportions of document is known, you can draw appropriate inner (for min document size) and outer (for max document size) bounding rectangles on preview (as shown on pict) and control that user positioned document within outer and over inner bounding rect. That is also helps to control right document angle. Also You can control tilt and orientation of smartphone as described in answers for this questions.
Then process preview image (or even its small copy) on-the-fly with lightweight quality estimation algorithms and inform user about low quality and its reason (e.g. low brightness, you can estimate brightness of outer rectangle region, for example, as described in this question) and, may be, block "take snapshot" control.

d9993 | train | template<class T> void f(T,
typename size_map<sizeof(&U::foo)>::type* = 0);
This doesn't work, because U does not participate in deduction. While U is a dependent type, during deduction for f it's treated like a fixed type spelled with a nondependent name. You need to add it to the parameter list of f
/* fortunately, default arguments are allowed for
* function templates by C++0x */
template<class T, class U1 = U> void f(T,
typename size_map<sizeof(&U1::foo)>::type* = 0);
So in your case because U::foo does not depend on parameters of f itself, you receive an error while implicitly instantiating S<X> (try to comment out the call, and it should still fail). The FCD says at 14.7.1/1
The implicit instantiation of a class template specialization causes the implicit instantiation of the declarations, but not of the definitions or default arguments, of the class member functions, member classes, static data members and member templates;
That is, if you implicitly instantiate S<X> the following function template declaration will be instantiated
template<class T> void S<X>::f(T,
typename size_map<sizeof(&X::foo)>::type* = 0);
Analysis on that template declaration will then find that it can't resolve the reference to X::foo and error out. If you add U1, the template declaration will not yet try to resolve the reference to U1::foo (since U1 is a parameter of f), and will thus remain valid and SFINAE when f is tried to be called. | unknown | |

If you log into Mongo and do a db.stats(), how much space are you using? That should tell you how close you are to the limit.
A: What size is the /data/db? This error is most likely from Mongo trying to allocate a new database file and that new file would push the size of the db past 2GB. MongoDB allocates database files in fairly large chunks so if you are anywhere near 2GB this could be the problem. | unknown | |
d9995 | train | When you map a folder from the host to the container, the host files become available in the container. This means that if your host has file a.txt and the container has b.txt, when you run the container the file a.txt becomes available in the container and the file b.txt is no longer visible or accessible.
Additionally file b.txt is not available in the host at anytime.
In your case, since your host does not have sample.sh, the moment you mount the directory, sample.sh is no longer available in the container (which causes the error).
What you want to do is copy the sample.sh file to the correct directory in the host and then start the container.

d9998 | train | It doesn't look to me like you need the model to be posted to your controller for what you're doing. In addition, yes, you absolutely can do this with jquery! On a side note, you could also do it with an Ajax.BeginForm() helper method, but lets deal with your jquery example.
Rather than complexify your jquery with your @Url.Action, you can simply call the path itself.
$("#btnrefresh").click(function () {
var ref = 'ControllerName/RefreshDepartments';
$.each(result, function (index, val) {
$('#whateverYourRenderedDropdownListHtmlObjectis')
.append($("<option></option>")
.attr("value", val.Text)
.text(val.Text));
});
});
Now, for your controller...
public JsonResult RefreshDepartments()
{
return Json(GetDepartments, JsonRequestBehavior.AllowGet);
}
private SelectList GetDepartments
{
var deparments = GetDepartments;
SelectList list = new SelectList(departments);
return list;
}
This is an alternative to returning the model. It allows you to manipulate the raw JSON instead. Hope it helps!
A: You almost did it all! Why don't you send the data, I mean list, by RefreshDepartments action? You sent a message to view, so you can send the list similarly and instead of alerting the result you can fill the dropdownlist. something like this:

{
return Json(new { departments = GetDepartments()}, JsonRequestBehavior.AllowGet);
}
$.getJSON(ref, data, function (result) {
$("#Department").html("");
